10-year interdisciplinary monitoring of organic stocklass, vegetable rotations at Warwick-HRI, Kirton, South Lincolnshire, UK
Provedor de dados: Organic Eprints
Autores: Schmutz, U; Rayns, F; Sumpton, P.
Interdisciplinary monitoring of an organic stockless farming system has been carried out over ten years on a fertile silty clay loam in the main vegetable production area of the UK. The results draw together economic outcomes with agronomy, soil science and agro-ecology. Organic management has been used at the Kirton research site since conversion of a 3.2 ha unit in 1997. There is great variability in crop yields and marketing results but overall a successful ongoing vegetable production system has been established. Soil fertility, weeds, pests and diseases have been managed successfully without imports of animal manures or green waste compost. Production costs are well controlled and marketable yields are good. However, because the site is a research...

11[beta]-hydroxysteroid dehydrogenase-type 2 evolved from an ancestral 17[beta]-hydroxysteroid dehydrogenase-type 2
Provedor de dados: Nature Precedings
Autores: Michael E. Baker.
11[beta]-hydroxysteroid dehydrogenase type-2 (11[beta]-HSD2) regulates the local concentration of cortisol that can activate the glucocorticoid receptor and mineralocorticoid receptor, as well as the concentration of 11-keto-testosterone, the active androgen in fish.  Similarly, 17[beta]-HSD2 regulates the levels of testosterone and estradiol that activate the androgen receptor and estrogen receptor, respectively.  Interestingly, although human 11[beta]-HSD2 and 17[beta]-HSD2 act at different positions on different steroids, these enzymes are paralogs.  Despite the physiological importance of 11[beta]-HSD2 and 17[beta]-HSD2, details of their origins and divergence from a common ancestor are not known.  An opportunity to understand their evolution is...

120,000 year record of sea ice in the North Atlantic

Autores: Maffezzoli, Niccolò; Vallelonga, Paul; Edwards, Ross; Saiz-lopez, Alfonso; Turetta, Clara; Kjær, Helle Astrid; Barbante, Carlo; Vinther, Bo; Spolaor, Andrea.
Although it has been demonstrated that the speed and magnitude of recent Arctic sea ice decline is unprecedented for the past 1,450 years, few records are available to provide a paleoclimate context for Arctic sea ice extent. Here we present a 120 kyr record of bromine enrichment from the RECAP ice core, coastal East Greenland, and reconstruct past sea ice conditions in the North Atlantic as far north as the entrance of the Arctic Ocean (50–85° N). Bromine enrichment has been previously employed to reconstruct first-year sea ice (FYSI) in the Canadian Arctic over the last glacial cycle. We find that during the last deglaciation, the transition from multi-year sea ice (MYSI) to FYSI started at ∼ 17.6 kyr, synchronous with sea ice reductions observed in the...

Therapeutic doses of 131I administered to thyrotoxic patients may cause thyroid failure. The present study used a rat model to determine thyroid function after the administration of different doses of 131I (64-277 µCi). Thirty male Fisher rats in the experimental group and 30 in the control group (untreated) were followed for 6 months. The animals were 4 months old at the beginning of the experiment and were sacrificed at an age of 9 months. Hormone concentration was determined before 131I administration (4-month-old animals) and three times following 131I administration, when the animals were 7, 8, and 9 months old. The thyroid glands were removed and weighed, their volume was determined and histopathological examination was performed at the end of the...

Tissue damage due to oxidative stress is directly linked to development of many, if not all, human morbidity factors and chronic diseases. In this context, the search for dietary natural occurring molecules with antioxidant activity, such as flavonoids, has become essential. In this study, we investigated a set of 41 flavonoids (23 flavones and 18 flavonols) analyzing their structures and biological antioxidant activity. The experimental data were submitted to a QSAR (quantitative structure-activity relationships) study. NMR 13C data were used to perform a Kohonen self-organizing map study, analyzing the weight that each carbon has in the activity. Additionally, we performed MLR (multilinear regression) using GA (genetic algorithms) and molecular...

13C Photoassimilate partitioning in sweet cherry (Prunus avium) during early spring
Provedor de dados: Ciencia e Investigación Agraria, Revista Latinoamericana en Ciencias de la Agricultura
Autores: Ayala,Marlene; Lang,Gregory A.
Stored reserves are critical for the early spring growth of reproductive and vegetative sinks in sweet cherry (Prunus avium L.). To study the distribution of carbon storage reserves on new, highly productive hybrid rootstocks in sweet cherry, an experiment was established using 5-yr-old cv. 'Regina' on the semi-vigorous rootstock 'Gisela®6' ('GI®6'). Using whole-canopy enclosure chambers, five trees were pulse-labeled three times with high levels of 13CO2 during the fall. At leaf drop, leaves, buds, wood, bark and roots were sampled for gas chromatography-mass spectrometry (GC-MS) analysis. The storage organs with the highest percentages of excess 13C atoms were the roots and the older wood in the trunks, branches and buds. During the spring, newly...

Autores: Martins,M.A.; Coletto,F.A.; Martins-Filho,O.A.; Marchini,J.S.; Basile-Filho,A.
The continuous intravenous administration of isotopic bicarbonate (NaH13CO2) has been used for the determination of the retention of the 13CO2 fraction or the 13CO2 recovered in expired air. This determination is important for the calculation of substrate oxidation. The aim of the present study was to evaluate, in critically ill patients with sepsis under mechanical ventilation, the 13CO2 recovery fraction in expired air after continuous intravenous infusion of NaH13CO2 (3.8 µmol/kg diluted in 0.9% saline in ddH2O). A prospective study was conducted on 10 patients with septic shock between the second and fifth day of sepsis evolution (APACHE II, 25.9 ± 7.4). Initially, baseline CO2 was collected and indirect calorimetry was also performed. A primer of 5 mL...

Provedor de dados: Electronic Journal of Biotechnology
Autores: Szymanowska-Powalowska,Daria.
Background The production of biofuels from renewable energy sources is one of the most important issues in industrial biotechnology today. The process is known to generate various by-products, for example crude glycerol, which is obtained in the making of biodiesel from rapeseed oil. Crude glycerol may be utilized in many ways, including microbial conversion to 1,3-propanediol (1,3-PD), a raw material for the synthesis of polyesters and polyurethanes. Results The paper presents results of a study on the synthesis of 1,3-propanediol from crude glycerol by a repeated batch method with the use of Clostridium butyricum DSP1. Three cycles of fermentation medium replacement were carried out. The final concentration of 1,3-PD was 62 g/L and the maximum...

14-3-3 proteins in apoptosis
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Rosenquist,M.
The once obscure members of the 14-3-3 protein family play significant roles in the determination of cell fate. By inhibiting the pro-apoptotic BAD (Bcl-2-antagonist of cell death) and the transcription factor FKHRL-1, 14-3-3 displays important anti-apoptotic characteristics. To date, five points of interaction of 14-3-3 with the apoptotic machinery have been identified. How these interactions are regulated still remains a mystery.

The Australian marine research, industry, and stakeholder community has recently undertaken an extensive collaborative process to identify the highest national priorities for wind-waves research. This was undertaken under the auspices of the Forum for Operational Oceanography Surface Waves Working Group. The main steps in the process were first, soliciting possible research questions from the community via an online survey; second, reviewing the questions at a face-to-face workshop; and third, online ranking of the research questions by individuals. This process resulted in 15 identified priorities, covering research activities and the development of infrastructure. The top five priorities are 1) enhanced and updated nearshore and coastal bathymetry; 2)...

15N uptake fom manure and fertilizer sources by three consecutive crops under controlled conditions
Provedor de dados: Revista Brasileira de Ciência do Solo
Autores: Garza,Héctor Mario Quiroga; Delgado,Jorge A.; Wong,José Antonio Cueto; Lindemann,William C.
There are several regions of the world where soil N analysis and/or N budgets are not used to determine how much N to apply, resulting in higher than needed N inputs, especially when manure is used. One such region is the North Central "La Comarca Lagunera", one of the most important dairy production areas of Mexico. We conducted a unique controlled greenhouse study using 15N fertilizer and 15N isotopic-labeled manure that was labeled under local conditions to monitor N cycling and recovery under higher N inputs. The manure-N treatment was applied only once and was incorporated in the soil before planting the first forage crop at an equivalent rate of 30, 60 and 120 Mg ha-1 dry manure. The 15N treatments were equivalent to 120 and 240 kg ha-1 (NH4)2SO4-N...

15Nitrogen transfer from legumes to neighbouring plants in multi-species grassland
Provedor de dados: Organic Eprints
Autores: Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J.
This study investigates the N transfer from legumes to  neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover  (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut.

15N-labed glycine synthesis
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Tavares,Claudinéia R.O.; Bendassolli,José A.; Coelho,Fernando; Sant'ana Filho,Carlos R.; Prestes,Clelber V.
This work describes a method for 15N-isotope-labeled glycine synthesis, as well as details about a recovery line for nitrogen residues. To that effect, amination of alpha-haloacids was performed, using carboxylic chloroacetic acid and labeled aqueous ammonia (15NH3). Special care was taken to avoid possible 15NH3 losses, since its production cost is high. In that respect, although the purchase cost of the 13N-labeled compound (radioactive) is lower, the stable tracer produced constitutes an important tool for N cycling studies in living organisms, also minimizing labor and environmental hazards, as well as time limitation problems in field studies. The tests were carried out with three replications, and variable 15NH3(aq) volumes in the reaction were used...

16S rRNA gene-based molecular analysis of mat-forming and accompanying bacteria covering organically-enriched marine sediments underlying a salmon farm in Southern Chile (Calbuco Island)
Provedor de dados: Gayana
Autores: Aranda,Carlos; Paredes,Javier; Valenzuela,Cristian; Lam,Phyllis; Guillou,Laure.
The mat forming bacteria covering organic matter-enriched and anoxic marine sediments underlying a salmon farm in Southern Chile, were examined using 16S rRNA gene phylogenies. This mat was absent in the sea bed outside the direct influence of the farm (360 m outside fish cages). Based on nearly complete 16S rRNA gene sequences (-1500 bp), mat-forming filamentous cells were settled as the sulphur-oxidizing and putatively dissimilative nitrate-reducing Beggiatoa spp., being closely related (up to 97% sequence identity) to Beggiatoa spp. identified in eutrophic shallow sediments in northern Europe (Danish Limfjorden and German Dangast inlets). Their phylogenetic affiliation was consistent with their morphology as vacuolated and sulphur-containing cells...

Autores: Richard Evans.
Delaware Water Gap National Recreation Area (&amp;#x201c;the park&amp;#x201d;) covers 28,000 ha along the Delaware River in Pennsylvania and New Jersey. Eastern hemlock forests cover 2,200 ha (8%) of the park, and are often associated with trout streams and scenic waterfalls. Activities like trout fishing, bird watching, and hiking are concentrated in hemlock forests, and many of these areas are officially designated as &amp;#x201c;Outstanding Natural Features&amp;#x201d; having &amp;#x201c;high intrinsic or unique values.&amp;#x201d; In 1989 hemlock woolly adelgid (HWA) was detected in the park, and since 1993 the park has conducted a program to address the threats that hemlock woolly adelgid and hemlock decline poses to park resources.

180 years of Botanical Investigations in Antarctica and the Role of Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Câmara,Paulo E.A.S.; Carvalho-Silva,Micheline.
ABSTRACT  Botany is one of the oldest sciences done above the 60oS parallel with more than 180 years passing since the first professional botanist collected plants in Antarctica. Far from being a barren place, plants constitute an important part of polar ecosystems. Brazil is one of only 29 countries in the world with consultative status and to currently develop botanical studies in Antarctica. We discuss the importance of polar science to Brazil and the role that Brazil has in the international austral-polar scientific community, as well as the importance of its newly inaugurated scientific station.

1978 OATS SURVEY REPORT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Welsch,   Delane E.; Stuthman,   Deon; Showman,   Alan.
A mail survey was conducted in 1977 of farmers who were thought to be oats producers, using names obtained from several lists. The purpose of the 1977 mail survey was to obtain answers to the following questions: (1) What kind of farmer grows oats, (2) Where does he grow them, (3)Why does he grow them, (4) How does he produce them? Answers to these questions should enable the breeding program and the Extension Program at the University of Minnesota to better address the problems of oat production and thus maintain, or hopefully improve the relative competitive ability of oats as a crop in Minnesota.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jackson,   Thomas E.; Irwin,   Scott H.; Good,   Darrel L.
The purpose of this research report is to present an evaluation of advisory service pricing performance in 1995 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1995. The average net advisory price across all 25 corn programs is $3.04 per bushel. The range of net advisory prices for corn is quite large, with a minimum of $2.34 per bushel and a maximum of $3.81 per bushel.  The average net advisory price across all 25 soybean programs is $6.61 per bushel.  As with corn, the range of net advisory prices for soybeans is substantial, with a minimum of $5.75 per bushel and a maximum of $7.92 per bushel.

1996 ANNUAL REPORT OF THE SOUTHEASTERN MINNESOTA FARM BUSINESS MANAGEMENT ASSOCIATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olson,   Kent D.; Westman,   Lorin L.; Nordquist,   Dale W.
In the Southeastern Association the average accrual net farm income in 1996 was $67,579 for the 61 farms included in this report. The decrease is due to lower inventory levels since the increase in gross cash income was higher than the increase in total cash farm expenses.  Even though this is a decrease of 8% from the 1995 average, the 1996 net farm income is still one of the highest on record.  Only in 1978, 1990, 1991, 1994 and 1995 was average nominal profit also greater than $50,000.  When adjusted by the Consumer Price Index (to provide a constant dollar or buying power comparison), the average 1996 profit is exceeded only in 1990 and 1995.  The 20% of these 61 farms with the highest net farm income had an average net farm income of $196,161 in 1996;...

Autores: Olson,   Kent D.; Talley,   Dary E.; Christensen,   James L.; Weness,   Erlin J.; Fales,   Perry A.; Nordquist,   Dale W.
For the Southwestern Association, average accrual net farm income was $62,699 in 1996 for the 203 farms included in this report. This is an increase of 9% from 1995 making 1996 another high income year in a job with large swings in income.  This volatility can be seen whether income is measured in nominal terms or constant dollars. The 20% of these 203 farms with the highest net farm income had an average profit of $157,052--an increase from 1995.  The low 20% of the farms had an average loss of -$6,010 in 1996, which was a smaller loss than in 1995. Average gross cash farm income in 1995 was $382,502--a 10% increase from 1995.  Four sources of sales made up 83% of total income in 1996: corn, beef finishing, hogs, and soybeans.  Corn sales increased 12%...

1997 ANNUAL REPORT OF THE SOUTHEASTERN MINNESOTA FARM BUSINESS MANAGEMENT ASSOCIATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olson,   Kent D.; Westman,   Lorin L.; Nordquist,   Dale W.
In the Southeastern Association the average net farm income in 1997 was $73,311 for the 64 farms included in this report.  This was an increase of 8.5% from 1996.  The increase is due to replenishment of inventories which had been depleted in 1996.  Total cash farm expenses increased 7%.  The 1997 net farm income is the highest on record.  When adjusted by the Consumer Price Index (to provide a constant dollar or buying power comparison), the average 1997 profit is exceeded only in 1990 and 1995.  (This accrual net farm income measure is calculated by subtracting cash farm expenses and depreciation from total cash farm income and adjusting the difference for changes in other capital and inventory items.)

Autores: Olson,   Kent D.; Weness,   Erlin J.; Christensen,   James L.; Anderson,   Robert D.; Fales,   Perry A.; Nordquist,   Dale W.
For the Southwestern Association, average net farm income was $40,598 in 1997 for the 208 farms included in this report.  This is a decrease of 35% from 1996 continuing the pattern of large swings in income.  Since costs changed very little, almost all of the decrease can be attributed to a decrease in gross income, specifically to decreases in the sales of corn and finished beef.  (Net farm income is calculated by subtracting total cash farm expense and depreciation from gross cash farm income and adjusting for changes in inventory items.)  After subtracting an opportunity cost for equity capital, labor and management earnings follow a similar but lower pattern.   As in previous years, the actual profit levels experienced by individual farms vary greatly...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

The average net farm income is $65,739 for the 60 farms included in the 1998 annual report of the Southeastern Minnesota Farm Business Management Association.  This is a decrease of 12% from 1997.  Even though gross cash farm income increased, cash expenses also increased and inventory values changed little (instead of increasing as in 1997).  Thus, 1998 net farm income is lower.  However, income is still at a high level compared to the early 1990s and the 1980s.

During the last 20 years, net farm income has been lower than  the 1998 level only in 1981 and 1985.  Since costs changed very little, almost all of the decrease can be attributed to decreases in hog sales, especially, to decreases in corn and soybean sales and substantial decreases in the value of inventories.

1a,25(OH)2D3 induces capacitative calcium entry involving a trpc3 protein in skeletal muscle and osteoblastic cells
Provedor de dados: Biological Research
Autores: SANTILLÁN,G; KATZ,S; BUITRAGO,C; BOLAND,R.
This work describes the involvement of TRPC proteins in capacitative calcium entry (CCE) induced by 1a,25-dihydroxy-vitamin-D3 [1a,25(OH)2D3] in chick skeletal muscle and in rat osteoblast-like cells (ROS 17/2.8) and the role of the vitamin D receptor (VDR) in this non-genomic rapid response mediated by the hormone. We propose that an endogenous TRPC3 protein mediates 1a,25(OH)2D3 modulation of CCE in these cells, which seems to implicate VDR-TRPC3 association and the participation of an INAD-like scaffold protein.

Provedor de dados: Horticultura Brasileira
Autores: Moretti,Celso Luiz; Araújo,Alessandra L.; Marouelli,Waldir Aparecido; Silva,Washington Luiz C.
Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity,...

Autores: Thewes,Fabio Rodrigo; Both,Vanderlei; Brackmann,Auri; Ferreira,Daniele de Freitas; Wagner,Roger.
ABSTRACT: Apple volatile aroma depends of complex interaction among organic compounds. The aim of the present study was to evaluate the effect of 1-methylcyclopropene (1-MCP) application on volatile profile and quality on 'Royal Gala' apples produced in Southern Brazil and stored under controlled atmosphere condition (CA; 1.0kPa O2+1.2kPa CO2; 0.5±0.1°C; 94±1% relative humidity). Volatile profile was determined after eight month of CA storage plus 7 days of shelf life via solid-phase microextraction (HS-SPME) and analyzed by gas chromatography coupled to mass spectrometer. In the volatile profile were identified 8 esters, 11 alcohols, 6 aldehydes, 6 acids, 2 ketones, 1 ether and 1 terpene. 1-MCP application reduced significantly the main volatile compounds...

Abstract Deletion-induced hemizygosity may unmask deleterious autosomal recessive variants and be a cause of the phenotypic variability observed in microdeletion syndromes. We performed complete exome sequencing (WES) analysis to examine this possibility in a patient with 1p13.2 microdeletion. Since the patient displayed clinical features suggestive of Noonan Syndrome (NS), we also used WES to rule out the presence of pathogenic variants in any of the genes associated with the different types of NS. We concluded that the clinical findings could be attributed solely to the 1p13.2 haploinsufficiency. Retrospective analysis of other nine reported patients with 1p13.2 microdeletions showed that six of them also presented some characteristics of NS. In all...

Autores: Bayer, Ch.
In continuation of the "Catalogue of the Bursidae" (cf. „Zoologische Mededeelingen", vol. 14, p. 224, 1932), I now publish a list of the Cymatiidae in the collection of our Museum, after having revised that family. We are indebted to the work of KESTEVEN, DALL, PILSBRY &amp; VANATTA, IREDALE, and others, for a more rational classification of the Cymatiidae. This family was formerly composed of two genera, viz. "Ranella" and "Triton" of older authors. In this century, however, as a result of researches on the dentition and the characters of the shell, these two genera have been placed into two separated families: the Cymatiidae and the Bursidae; moreover, according to the above-mentioned characteristics, the tritonoid "Ranellae", belonging to the sections...

2- Isopentenyladenine in the induction of direct somatic embryogenesis capacity of Coffea arabica L.
Provedor de dados: Ciência Rural
Autores: Alves,Ivanilda dos Santos; Carmazini,Valéria Cristina Barbosa; Santos,Cosme Damião dos; Almeida,Julieta Andrea Silva de.
ABSTRACT:  This study evaluated the effect of different concentrations of 2-isopentenyladenine (2-iP) on the direct somatic embryogenesis capacity of the Mundo Novo cultivar of Coffea arabica. Leaf explants were cultivated with half the MS salt concentration and the addition of sucrose (20gL-1) and 2-iP (0; 2.5; 5; 7.5 and 10µM). The 2-iP doses of 7.5 and 10µM produced the greatest responses with respect to the percentage of explants with embryogenic structures and the size of the embryogenic structures. However, the greatest production of somatic embryos occurred on the explants treated with 10µM of 2-iP, followed by 7.5µM, whereas their production was absent or reduced with 0 and 5µM, respectively.

2 øko-planter sviner mindre end én
Provedor de dados: Organic Eprints
Autores: Kokkedal, Hanne.
Samdyrkning kan bruges til at reducere kvælstofudvaskning. På ESOF konferencen om uddannelser i København viste lektor Hanne L. Kristensen og Ph.D. studerende Yue Xie fra Institut for Fødevarer Aarhus Universitet hvorledes rødder fra porrer, blomkål og farvevajd vokser når de vokser hver for sig eller sammen i lange jordfyldte rør. Samdyrkning af fx. porre der har et overfladisk rodsystem med farvevajd der har et dybt rodsystem øger planternes evne til at optage kvælstof fra jorden og nedsætter dermed risikoen for kvælstofudvaskning  end når porre vokser alene. Demonstrationen var en del af projektet InterVeg under CORE organic II programmet (GUDP).

In his review of the palaeozoology of Java, K. Martin could in 1919, record 49 foraminifera from tertiary strata of Java, on the strength of a critical study of the existant literature, and especially on the strength of his own studies and knowledge of the above mentioned fossils (Bibl. 49). In composing the following list of the Foraminifera I have only been able to perform such a critical study for a few families. For the greater part, however, I have had to restrict myself to recording the results obtained by others, and even therein I have been obliged to restrict myself.

Provedor de dados: Organic Eprints
Autores: Bachinger, Johann; Bloch, Ralf; Reckling, Moritz; Stein-Bachinger, Karin.
Acht Felder der Versuchsstation des ZALF in Müncheberg in Nordostdeutschland wurden 1993 als Modellbetrieb mit einer Leguminosen-betonten Fruchtfolge auf Ökologischen Landbau umgestellt. Je Feld wurde 1995 ein Monitoringversuch mit je  5 Ernte- bzw. Beprobungsparzellen angelegt. Neben Ernteerhebungen erfolgte eine jährliche Krumenbeprobung zur Untersuchung der Entwicklung der Gehalte an organischem Kohlenstoff (Corg) und Stickstoff (Norg) sowie der P- und K-Verfügbarkeit. Eine deutliche Zunahme der Corg-Gehalte zeigte sich nur auf den Flächen mit Texturklasse Sand. Dagegen stiegen die Norg-Gehalte auch auf den besseren Böden, allerdings in geringerem Maße, an. Die P-Verfügbarkeit pegelte sich nach einem anfänglichen Rückgang auf Werte der Versorgungsstufe...

Provedor de dados: Organic Eprints
Autores: Reckling, Moritz; Döring, Thomas F.; Bloch, Ralf; Stein-Bachinger, Karin; Bachinger, Johann.
Auf dem Modellbetrieb für Ökolandbau in Müncheberg wurden von 1993 bis 2013 Feldversuche zur Ermittlung der Ertragsstabilität von zwei Körnerleguminosen (Schmalblättrige Lupine und Futtererbse), Wintergetreide (Roggen und Weizen), Hafer und Silomais durchgeführt. Zwei orthogonale Datensätze wurden genutzt um die temporären Ertragsschwankungen der Einzelkulturen zu vergleichen. Beide Körnerleguminosen zeigten die geringste Ertragsstabilität von allen untersuchten Kulturen. Dies war sowohl für varianzbasierte als auch für regressionsbasierte Stabilitätsparameter der Fall. Gründe für die geringe Ertragsstabilität sind unzureichend bekannt. Es müssen Strategien für das Management entwickelt werden, um mit den großen Schwankungen umzugehen.

2000 ANNUAL REPORT OF THE SOUTHEASTERN MINNESOTA FARM BUSINESS MANAGEMENT ASSOCIATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olson,   Kent D.; Westman,   Lorin L.; Nordquist,   Dale W.
The average net farm income is $77,672 for the 58 farms included in the 2000 annual report of the Southeastern Minnesota Farm Business Management Association.  This is an increase of 17% from 1999.  The median or middle income was $39,675, considerably lower than the average.  Even though gross cash farm income decreased more than the decrease in cash expenses, net farm income increased because  depreciation decreased and inventory values increased.  Income is still at a high level compared to the early 1990s and the 1980s.    As in previous years, the income levels experienced by individual farms vary greatly from the overall average.  When the net farm incomes for the 58 farms in the report were ranked from lowest to highest, the resulting graph shows...

Average net farm income was $81,750 in 2000 for the 212 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  The median or middle income was $69,414.  This is the second annual increase from the extremely low levels of 1998.  Almost all of the increase can be attributed to the increase in the value of inventories, government payment, and the decrease in depreciation charge.     However, the change in depreciation was almost entirely due to a change in the accounting procedures, not a change in purchasing behavior by farmers.  Using the "new" depreciation rules, net farm income (NFI) in the previous 5 years was estimated to be higher than when the "old" rules were used.  For example, the "new" NFI was...

2000 OUTLOOK OF THE U.S. AND WORLD WHEAT INDUSTRIES, 1999-2001
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world wheat markets for the 1999-2009 period by using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.  Both the U.S. and world wheat economies are predicted to be improving for the next ten years.  World demands for both common and durum wheat are expected to grow faster than world production of the two wheat classes, resulting in gradual increases in prices of the wheats, which are predicted to increase 36% for durum wheat and 23% for common wheat for the 1999-2009 period.  However, the prices are expected to recover slowly for the next 2-3 years.  World trade volumes of...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Olson,   Kent D.; Westman,   Lorin L.; Nordquist,   Dale W.
The average net farm income was $60,978 for the 59 farms included in the 2001 annual report of the Southeastern Minnesota Farm Business Management Association.  This was a decrease of 21% from 2000 (Figure 1).   Even though gross cash farm income increased more than cash expenses, the decrease in net farm income is due in large part to a large decrease in the inventory value of crops and feed.    As in previous years, the income levels experienced by individual farms vary greatly from the overall average.  When the net farm incomes for the 59 farms in the report were ranked from lowest to highest, the resulting graph shows how much the incomes do vary (Figure 2).  Several farms experienced negative incomes, and several experienced very high incomes.  Most...

Average net farm income was $36,614 in 2001 for the 207 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  This is a sharp drop (55%) from the average net farm income of $81,750 in 2000 (Figure 1).

Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2001-2011 by using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes.  Both the U.S. and world sugar economies are predicted to improve over the next 10 years after the current over supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in gradually increasing Caribbean sugar prices from 7.81 cents/lb in 2001 to 12.05 cents/lb in 2011. The U.S. wholesale price of sugar is projected to increase from 21.7 cents/lb in 2001 to 25.2 cents/lb in 2011, if the United States maintains its sugar programs. World...

2004 update of overview supply and demand of organic concentrated feed in the EU
Provedor de dados: Organic Eprints
Autores: Padel, Susanne; Lowman, Steve.
Summary of key trends and changes in 2004  The total organic flock in the EU 25 appears to have increased by between 6 and 9 per cent, depending on stock category. Greatest increases occurred for sheep in France, Italy, Spain and the UK. In the other livestock categories, increases in some countries were balanced by decline in others, leading to overall small increases (see Table 3 update1).    The production area of organic cereals increased between 2003 and 2004 by approximately 6 %. Significant reduction (9%) in the cereals area seems to have occurred in Italy, Spain and Hungary, whereas the area increased in Austria, Greece and Portugal (see Table 4 update).    The area for pulses appears to have declined by a further 14% in the EU 25. Reductions...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Whipker,   Linda D.; Akridge,   Jay T.
Precision technologies are now well-integrated into the agricultural industry – both at the farm level and at the crop input dealer level.  No longer are crop input dealers only using the technologies to bring new services to their customers, they are also utilizing the technology in their own businesses to improve the efficiency and effectiveness of their operations.  In early 2008, Crop Life magazine and Purdue University’s Center for Food and Agricultural Business conducted a survey for the 13th consecutive year to assess the adoption of precision agriculture practices in the U.S. from the perspective of the retail crop input dealer.  The questionnaire was mailed to 2500 retail crop input dealerships across the U.S.  A total of 298 questionnaires were...

2009 Annual Report of the Southwestern Minnesota Farm Business Management Association
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nordquist,   Dale W.; Kurtz,   James N.; Nitchie,   Donald L.; Paulson,   Garen J.; Froslan,   Janet M.; Christensen,   James L.
Average net farm income was $69,787 in 2009 for the 95 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  Average earnings decreased by 63%  from $190,901 in 2008.   This continues the downward trend that began in 2008 after six years of steady increases.  As expected, low incomes for virtually all types of livestock operations pulled the average down, and some livestock farms sustained large losses.  Crop farms, on average, were profitable but also earned much lower incomes compared to recent years. Median net farm income, or the income earned by the middle farm, was $96,130, substantially higher than the average.  This indicates that the average was pulled down or skewed by large losses sustained by...

2009 PRECISION AGRICULTURAL SERVICES DEALERSHIP SURVEY RESULTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Whipker,   Linda D.; Akridge,   Jay T.
In the spring of 2009, Crop Life magazine and Purdue University’s Center for Food and Agricultural Business conducted a survey of crop input dealers for the 14th consecutive year. In February, a questionnaire was mailed to 2500 Crop Life retail crop input dealership readers across the US. (See Appendix I to this report for a copy of the questionnaire.) A total of 258 questionnaires were returned, with 241 being usable. This provided an effective response rate of 9.6 percent, the lowest response rate in the 14 year history of the project. (In prior years, response rates have ranged from a high of 38 percent in 1996 to a low of 11 percent in 2001 and 2008.) Consistent with previous surveys, dealerships were asked questions about the types of precision...

Autores: Nordquist,   Dale W.; Kurtz,   James N.; Nitchie,   Donald L.; Paulson,   Garen J.; Froslan,   Janet M.; Woodford,   John L.
Average net farm income was $322,165 in 2010 for the 97 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  Average earnings increased by 362%  from $69,787 in 2009 (Figure 1).  Inflations adjusted profits rebounded after a downturn in 2009 that was caused primarily by low profits in the livestock sectors.  Strong yields, substantially higher crop inventory values, and rebounding profitability of the livestock sectors led the way to much higher profits in 2010.   Highlights of association financial results for 2010:  Entire report is available at: http://www.cffm.umn.edu/Publications/Pubs/FBMA/SW_MN_FBMA_2010.pdf• Median net farm income, or the income earned by the middle farm, was $234,879,...

2011 German Escherichia coli O104:H4 outbreak: Alignment-free whole-genome phylogeny by feature frequency profiles
Provedor de dados: Nature Precedings
Autores: Man Kit Cheung; Lei Li; Wenyan Nong; Hoi Shan Kwan.
Accuracy of SNP-based whole-genome phylogeny reconstruction relies heavily on quality of sequence alignment which is particularly hindered by poorly assembled genomes. Alignment-free methods might provide additional insights. Here, we constructed a whole-genome phylogeny of 10 isolates from the current German E. coli outbreak against 30 existing E. coli genomes as well as that of a historical EHEC isolate using the alignment-free feature frequency profile method. Our results revealed a high similarity among E. coli isolates from the current outbreak and the historical EHEC being the most closely related isolate sequenced thus far.

2011 Updated Arkansas Global Rice Model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wailes,   Eric J.; Chavez,   Eddie C.
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework.  The model is disaggregated by five world regions: Africa, the Americas, Asia, Europe, and Oceania.  Each region includes country models which have a supply sector, a demand sector, a trade, stocks and price linkage equations.  All equations used in this model are estimated using econometric procedures or identities.  Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy.  Individual country...

20th century fluctuations in the abundance of siliceous microorganisms preserved in the sediments of the Puyuhuapi Channel (44° S), Chile
Provedor de dados: Revista Chilena de Historia Natural
Autores: REBOLLEDO,LORENA; LANGE,CARINA B.; FIGUEROA,DANTE; PANTOJA,SILVIO; MUÑOZ,PRÁXEDES; CASTRO,RODRIGO.
We present a 100-year reconstruction of siliceous export production from sediments of the Puyuhuapi Channel (44° S, 70° W) in the Chilean fjords. We use accumulation rates and concentrations of diatoms and silicoflagellates, organic carbon (Corg) and biogenic opal (SiOPAL) as proxies of export production, and fluctuations in the contribution of freshwater diatoms as proxies of rainfall in the hinterland and river runoff. Box core sediments collected at two sites within the Puyuhuapi Channel were analyzed: Station 35 (at the head of the fjord; 56 m water depth) and Station 40 (in the middle of the Channel; 270 m water depth). Surface sedimentation rates were 0.75 cm yr-1 at Station 35 and 0.25 cm yr-1 at Station 40. SiOPAL content averaged ~ 4 % at both...

We determined the frequency of large rearrangements and point mutations in 130 Brazilian patients with 21-hydroxylase deficiency and correlated genotype with phenotype. The frequency of CYP21 deletions was lower (4.4%) than in most of the previous series described, whereas the frequency of large gene conversions was similar to the frequency reported in the literature (6.6%). The most frequent point mutations were I2 splice (41.8% in salt wasting - SW), I172N (32.6% in simple virilizing - SV) and V281L (40.2% in the late onset form - LO). The frequency of the nine most common point mutations was similar to that reported for other countries. The 93 fully genotyped patients were classified into 3 mutation groups based on the degree of enzymatic activity...

2,3,8-Trisubstituted Quinolines with Antimalarial Activity
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: MARTINEZ,PABLO D.G.; KRAKE,SUSANN H.; POGGI,MAITIA L.; CAMPBELL,SIMON F.; WILLIS,PAUL A.; DIAS,LUIZ C.
ABSTRACT Combination therapy drugs are considered a fundamental way to control malaria as it mimimizes the risk of emergence of resistance to the individual partner drugs. Consequently, this type of therapy constitutes a driving force for the discovery of new drugs with different modes of action, since this will provide options for combining different drugs to achieve the optimum antimalarial treatment. In this context, a 2,3,8-trisubstitued quinoline compound was found in a high throughput screen (HTS) to show an excellent inhibition of P. falciparum NF54 (IC50 = 22 nM) and low cytotoxicity. We performed a detailed evaluation of the substituents to improve the metabolic stability and solubility liabilities of the original hit and identified derivatives...

Provedor de dados: Planta Daninha
Autores: SILVA,J.R.O.; MARQUES,J.N.R.; GODOY,C.V.C.; BATISTA,L.B.; SILVA,A.A.; RONCHI,C.P.
ABSTRACT: The hormesis effect of 2,4-D, applied at two stages of soybean development, on the physiological components of crop yield, was investigated. Soybean seeds of the cultivar ‘AG 3680 IPRO’ were sown in pots containing 7 L of a substrate and kept in a greenhouse. A randomized complete block design with four replicates was used. Eighteen treatments were tested, arranged in a split-plot scheme. The plots consisted of two stages of herbicide application (V4 and V6), and the split-plots were arranged by nine 2,4-D doses (0, 5, 10, 15, 20, 25, 30, 40, and 50 g ha-1). At the time of harvest, 100 days after sowing, significant interactions between crop development stages and 2,4-D doses were observed for the number of nodes in the main stem (NNMS) and the...

2(5H)-Furanone: a prospective strategy for biofouling-control in membrane biofilm bacteria by quorum sensing inhibition
Provedor de dados: Brazilian Journal of Microbiology
Autores: Ponnusamy,Kannan; Paul,Diby; Kim,Young Sam; Kweon,Ji Hyang.
Biofouling of membranes demands costly periodic cleaning and membrane replacement. A sustainable and environmentally friendly solution for maintenance is not available and would be of great interest for many purposes including economical. As complex biofilm formation by environmental strains is the major cause of biofouling and biofilm formation in most cases are controlled by N-Acylhomoserine lactone (AHL)mediated Quorum Sensing (QS). An effort was made to understand the appropriateness of 2(5H)-furanone, to use against biofouling of membranes. QS inhibition activity by 2(5H)-furanone was studied using bioindicator strains and known AHLs of different acyl chain lengths. The biofilm inhibition was studied by growth analysis on polystyrene plate of...

Trench-parallel thrust faults verging both landward and seaward were mapped in the portion of wedge located between northern Sumatra and the Indian-Indonesian boundary. The spatial aftershocks distribution of the 26th December 2004 earthquake shows that the post-seismic motion is partitioned along two thrust faults, the Lower and Median Thrust Faults, the latter being right-laterally offset by a N-S lower plate fracture zone located along the 93.6 degrees N meridian. Between February 2005 and August 2005, the upper plate aftershock activity shifted from southeast of this fracture zone to northwest of it, suggesting that the lower plate left-lateral motion along the fracture zone may have induced a shift of the upper plate post-seismic activity along the...

2-Bromo-1,4-naphthoquinone: a potentially improved substitute of menadione in Apatone™ therapy
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Graciani,F.S.; Ximenes,V.F.
Apatone™, a combination of menadione (2-methyl-1,4-naphthoquinone, VK3) and ascorbic acid (vitamin C, VC) is a new strategy for cancer treatment. Part of its effect on tumor cells is related to the cellular pro-oxidative imbalance provoked by the generation of hydrogen peroxide (H2O2) through naphthoquinone redox cycling. In this study, we attempted to find new naphthoquinone derivatives that would increase the efficiency of H2O2 production, thereby potentially increasing its efficacy for cancer treatment. The presence of an electron-withdrawing group in the naphthoquinone moiety had a direct effect on the efficiency of H2O2 production. The compound 2-bromo-1,4-naphthoquinone (BrQ), in which the bromine atom substituted the methyl group in VK3, was...

Political attention has increasingly focused on limiting warming to 2°C. However, to date the only mitigation commitments accompanying this target are the so-called Copenhagen pledges, and these pledges appear to be inconsistent with the 2°C objective. Diverging opinions on whether this inconsistency can or should be resolved have been expressed. This paper clarifies the alternative assumptions underlying these diverging view points and explicits their implications. It first gives simple visualizations of the challenge posed by the 2°C target. It then proposes a “decision tree”, linking different beliefs on climate change, the achievability of different policies, and current international policy dynamics to various options to move forward on climate change.

This study presents the modelling of 2-D and 3-D wide-angle seismic data acquired on the complex, volcanic passive margin of the Voring Plateau, off Norway. Three wide-angle seismic profiles were shot and recorded simultaneously by 21 Ocean Bottom Seismometers, yielding a comprehensive 3-D data set, in addition to the three in-line profiles. Coincident multi-channel seismic profiles are used to better constrain the modelling, but the Mesozoic and deeper structures are poorly imaged due to the presence of flood basalts and sills. Velocity modelling reveals an unexpectedly large 30 km basement high hidden below the flood basalt. When interpreted as a 2-D structure, this basement high produces a modelled gravity anomaly in disagreement with the observed...

2D and 3D seismic simulation for fault modeling: exploratory revision from the Gullfaks field
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Siddiqui, Numair A.; Mathew, Manoj. J.; Menier, David; Hassaan, M.
2D and 3D seismic data have emerged as a key tool in the oil and gas industry to visualize and understand subsurface morphology and boundaries. In addition to providing excellent structural images, the dense sampling of 2D and 3D survey can sometimes make it possible to map reservoir quality and the distribution of hydrocarbon with well-marked limitations. Here we use 2D and 3D seismic data to map and interpret basic structures and fault lines to construct 2D and 3D base fault models of the Gullfaks field, while avoiding common pitfalls. This work also highlights important concepts and principles that allow selection, interpretation and simulation of particular areas containing hydrocarbon traps through the comparison of different maps such as time...

Autores: Mouche, Alexis; He, W.; Husson, R.; Guitton, Gilles; Chapron, Bertrand; Li, Huimin.
Sentinel-1 A now routinely acquires data over the ocean since 2014. Data are processed by ESA through the Payload Data Ground Segment up to Level-2 for Copernicus users. Level-2 products consist of geo-located geophysical parameters related to wind, waves and ocean current. In particular, Sentinel-1A wave measurements provide 2D ocean swell spectra (2D wave energy distribution as a function of wavelength and direction) as well as integrated parameters such as significant wave height, dominant wavelength and direction for each partition. In 2016, Sentinel-1 B will be launched by ESA and GF-3 by CNSA. Then in 2018, CFOSAT (China France Oceanography Satellite project), a joint mission from the Chinese and French Space Agencies, will be launched. They will...

2D vortex interaction in a non-uniform flow
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Perrot, Xavier; Carton, Xavier.
In a two-dimensional incompressible fluid, we study the interaction of two like-signed Rankine vortices embedded in a steady shear/strain flow. The numerical results of vortex evolutions are compared with the analytical results for point vortices. We show the existence of vortex equilibria, and of merger for initial distances larger than those without external flow. The evolutions depend on the initial orientation of the vortices in the external flow.

2-Methyl 2-butanol suppresses human retinoblastoma cells through cell cycle arrest and autophagy
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Li,Xiangyun; Zhu,Xiangxiang; Xu,Chong; Wu,Jianhua.
2-Methyl-2-butanol (MBT) is a chemical compound from the group of alcohols more specifically pentanols, which has shown an excellent anti-cancer activity in our previous study. However, its mechanism of action remains unclear. The present study was designed to investigate the anti-cancer effect of MBT on human retinoblastoma cells. The results showed that the use of MBT leads to HXO-RB44 cell death but is cytotoxic to normal cells at higher concentrations. It showed a dose- as well as a time-dependent inhibition of HXO-RB44 cells. P27 is a cell cycle inhibitory protein, which plays an important role in cell cycle regulation whereas cyclin-B1 is a regulatory protein involved in mitosis. MBT increased the cell cycle arrest in a dose-dependent manner by...

Autores: Abbasi,Muhammad Athar; Aziz-ur-Rehman,; Qureshi,Muhammad Zahid; Khan,Farhan Mehmood; Khan,Khalid Mohmmed; Ashraf,Muhammad; Afzal,Iftikhar.
This manuscript reports the synthesis of a series of N-substituted derivatives of 2-phenitidine. First, the reaction of 2-phenitidine (1) with benzene sulfonyl chloride (2) yielded N-(2-ethoxyphenyl) benzenesulfonamide (3), which further on treatment with sodium hydride and alkyl halides (4a-g) furnished into new sulfonamides (5a-g). Second, the phenitidine reacted with benzoyl chloride (6) and acetyl chloride (8) to yield the reported N-benzoyl phenitidine (7) and N-acetyl phenitidine (9), respectively. These derivatives were characterized by infrared spectroscopy, ¹H-NMR, and EI-MS, and then screened against acetylcholinesterase, butylcholinesterase, and lipoxygenase enzyme, and were found to be potent inhibitors of butyrylcholinesterase alone.

トラクタのけん引性能を評価するための一つの方法として, 2輪駆動トラクタのけん引効率の予測を行なった。予測精度を検討するために, トラクタの機体条件ならびに平均円すい指数からけん引効率等を予測すると共に, 土壌密度を変えた圃場でけん引性能試験を行ない実測データを収集した。けん引力およびけん引効率の実測値の予測値に対する偏差と予測最大値との比を偏差率として定義し求め, 予測精度を検討した。その結果, 全データの偏差率の平均値は, けん引力で0.07%, けん引効率で-0.29%となり, 提案モデルは高い精度で予測できることを示した。 A prediction of the tractive efficiency of a two-wheel drive tractor was conducted with tractor dimensions and average cone indexes. Experimental data in a field for the discussion of the prediction accuracy were obtained through tractor drawbar pull tests. The deviations of the measured data to the predicted one of drawbar pull and tractive efficiency were calculated，and the deviation rates which were defined as the ratio of the deviation to the predicted maximums of the drawbar pull and the...

Notwithstanding the fact that representants of this group were already known to Prof. C. G. Ehrenberg, the great micropaleontologist of the first half of the 19th century and subsequent authors have mentioned them from various localities, they have remained almost unknown. Their organic nature too has not always been recognised. In 1843 Prof. Ehrenberg referred them to his group „Polygastern” with the name Actiniscus; in his „Microgeologie”, however, they were considered as inorganic bodies and mentioned as „Crystalldrusen"", „Seheibensternchen"" or „Crystalloids"" (Bibl. 2, p. 115, p. 156, etc.). Very accurate descriptions of these forms are given by Mr. Hill from Barbados, where they are found in the calciferous oceanic deposits lying under the famous...

Productivity of tropical lowland moist forests is often limited by availability and functional allocation of phosphorus (P) that drives competition among tree species and becomes a key factor in determining forestall community diversity. We used non-target 31P-NMR metabolic profiling to study the foliar P-metabolism of trees of a French Guiana rainforest. The objective was to test the hypotheses that P-use is species-specific, and that species diversity relates to species P-use and concentrations of P-containing compounds, including inorganic phosphates, orthophosphate monoesters and diesters, phosphonates and organic polyphosphates. We found that tree species explained the 59% of variance in 31P-NMR metabolite profiling of leaves. A principal component...

ABSTRACT: The 'Montenegrina' mandarin ( Citrus deliciosa Tenore) is widely cultivated in southern Brazil. This cultivar has a great tendency for alternate bearing, requiring thining of the fruit. However, the chemical thinners studied until now in this cultivar have not been successful. The objective of this research was to evaluate the effect of 3,5,6-trichloro-2-pyridinyloxyacetic acid (3,5,6-TPA) on the production and fruit quality of the 'Montenegrina' mandarin, in comparison with hand thinning and the options of chemical thinning previously studied. Hand thinning and no thinning were used as controls. Ethephon was applied in three doses: 200mg L-1, 300mg L-1 or 200mg L-1 + 3% urea; or 3,5,6-TPA, in four doses: 10, 20, 30 or 40mg L-1.

3D Dense Reconstruction of Plant or Tree Canopy Based on Stereo Vision
Provedor de dados: Agricultural Engineering International : The CIGR e-journal
Autores: Ni, Zhijiang; Burks, Thomas F.
Three dimensional (3D) reconstruction of the plant or tree canopy is an important step in order to measure canopy geometry, such as, height, width, volume, and leaf cover area. In this research, binocular stereo vision was used to recover the 3D information of the canopy. A revised camera calibration method was provided to calibrate the cameras in world coordinate system. Only two images were used to realize a dense reconstruction. These two images were firstly rectified to make sure the corresponding feature points in the left and right images were on the same horizontal line. An efficient large scale stereo matching (ELAS) algorithm was used to find the disparity map. The plant or tree canopy was finally reconstructed based on these calibrated camera...

3D model of lamprey estrogen receptor with estradiol and 15[alpha]-hydroxy-estradiol
Provedor de dados: Nature Precedings
Autores: Michael E. Baker; David J. Chang; Charlie Chandsawangbhuwana.
Lamprey, a basal vertebrate, contains orthologs of the estrogen receptor (ER), progesterone receptor and corticoid receptor.  A perplexing property of lamprey is that 15[alpha]-hydroxy-steroids are active steroids.  For example, 15[alpha]-hydroxy-estradiol [15[alpha]-OH-E2] is the estrogen, instead of estradiol (E2).  To investigate how 15[alpha]-OH-E2 binds lamprey ER, we constructed a 3D model of the lamprey ER with E2 and 15[alpha]-OH-E2.  Our 3D model shows that S[delta] on Met-409 can form a hydrogen bond with the 15[alpha]-hydroxyl on 15[alpha]-OH-E2.  In human ER[alpha], the corresponding residue Ile-424 has a van der Waals contact with 15[alpha]-OH-E2.  BLAST analysis of GenBank indicates that among vertebrate ERs, only lamprey ER contains a...

3D modelling of seasonal evolution of Loire and Gironde plumes on Biscay Bay continental shelf
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lazure, Pascal; Jegou, Anne-marie.
A 3D model of the Atlantic shelf has been developed and applied to study shelf dynamics and evolution of hydrology. The model takes the combined effects of tide, wind, river discharges and surface heat flux into account. Time scales vary from 1 day to several years. Following a brief description of the model and forcing variables, the behaviour of the Loire and Gironde plumes is described, first for winter and spring, then over a period of several years, under realistic forcing. The results show that plume evolution depends on the high Variability of river runoff and winds. Model simulations performed over 7 years (1990 to 1996) have highlighted several features of these plumes: 1) In early winter and periods of high river runoff, plumes usually spread...

3D Print of the Maxillary Sinus for Morphological Study
Provedor de dados: International Journal of Morphology
Autores: Araneda,Nadia; Parra,Marcelo; Valdivia Osorio,José; Olate,Sergio.
The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of...

3-D sediment-basement tomography of the Northern Marmara trough by a dense OBS network at the nodes of a grid of controlled source profiles along the North Anatolian fault
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bayrakci, Gaye; Laigle, Mireille; Becel, A.; Hirn, A.; Taymaz, T.; Yolsal-cevikbilen, S.
A 3-D tomographic inversion of first arrival times of shot profiles recorded by a dense 2-D OBS network provides an unprecedented constraint on the P-wave velocities heterogeneity of the upper-crustal part of the North Marmara Trough (NMT), over a region of 180 km long by 50 km wide. One of the specific aims of this controlled source tomography is to provide a 3-D initial model for the local earthquake tomography (LET). Hence, in an original way, the controlled source inversion has been performed by using a code dedicated to LET. After several tests to check the results trade-off with the inversion parameters, we build up a 3-D a priori velocity model, in which the sea-bottom topography, the acoustic and the crystalline basements and the Moho interfaces...

The development of 3D printing in recent years opens up a vast array of possibilities in the field of flow analysis. In the present study, a new 3D-printed flow system has been developed for the selective spectrophotometric determination of lead in natural waters. This system was composed of three 3D-printed units (sample treatment, mixing coil and detection) that might have been assembled without any tubing to form a complete flow system. Lead was determined in a two-step procedure. A preconcentration of lead was first carried out on TrisKem Pb Resin located in a 3D-printed column reservoir closed by a tapped screw. This resin showed a high extraction selectivity for lead over many tested potential interfering metals. In a second step, lead was eluted by...

Autores: Mattio, Elodie; Robert-peillard, Fabien; Vassalo, Laurent; Branger, Catherine; Margaillan, Andre; Brach-papa, Christophe; Knoery, Joel; Boudenne, Jean-luc; Coulomb, Bruno.
In recent years, the development of 3D printing in flow analysis has allowed the creation of new systems with various applications. Up to now, 3D printing was mainly used for the manufacture of small units such as flow detection cells, preconcentration units or mixing systems. In the present study, a new 3D printed lab-on-valve system was developed to selectively quantify lead and cadmium in water. Different technologies were compared for lab-on-valve 3D printing. Printed test units have shown that stereolithography or digital light processing are satisfactory techniques for creating complex lab-on-valve units. The lab-on-valve system was composed of two columns, eight peripheral ports and a central port, and a coil integrating baffles to increase mixing...

4-Aminopyridine inhibits the neuromuscular effects of nitric oxide and 8-Br-cGMP
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Queiroz,R.N.; Ramos,E.R.P.; Alves-Do-Prado,W.
The effects induced by nitric oxide (NO) in different tissues depend on direct and/or indirect interactions with K+ channels. The indirect interaction of NO is produced by activation of guanylyl cyclase which increases the intracellular cGMP. Since NO, cGMP and 4-aminopyridine alone induce tetanic fade and increase amplitude of muscular contractions in isolated rat neuromuscular preparations, the present study was undertaken to determine whether or not the neuromuscular effects of NO and 8-Br-cGMP can be modified by 4-aminopyridine. Using the phrenic nerve and diaphragm muscle isolated from male Wistar rats (200-250 g), we observed that L-arginine (4.7 mM) and 8-Br-cGMP (18 µM), in contrast to D-arginine, induced an increase in the amplitude of muscle...

Abstract  Background: There is still a need for new alternatives in pharmacological therapy for neglected diseases, as the drugs available show high toxicity and parenteral administration. That is the case for the treatment of leishmaniasis, particularly to the cutaneous clinical form of the disease. In this study, we present the synthesis and biological screening of eight 4-phenyl-1,3-thiazol-2-amines assayed against Leishmania amazonensis. Herein we propose that these compounds are good starting points for the search of new antileishmanial drugs by demonstrating some of the structural aspects which could interfere with the observed activity, as well as suggesting potential macromolecular targets.  Methods: The compounds were easily synthesized by the...

50 anos de pesquisas em limnologia na Amazônia
Provedor de dados: Acta Amazonica
Autores: Sioli,Harald.
Constitui-se o presente trabalho da transcrição integral da palestra realizada pelo Dr. Harald Sioli (1910-2004) no Seminário da Amazônia, em 10 de agosto de 1990, quando numa última viagem ao Amazonas, ao completar 80 anos de idade, foi homenageado pelos colegas e a convite do INPA falou sobre "50 anos de pesquisas em limnologia na Amazônia" que, segundo suas próprias palavras, foram "os dias mais decisivos de minha vida". O texto pode ser dividido em duas partes: a primeira se refere à história pessoal - da chegada ao Brasil, de como descobriu a Amazônia e sobreviveu, no interior do Amazonas e Pará, à 2.ª Guerra Mundial, até se tornar pesquisador do INPA e firmar o Convênio INPA/Max Planck. A segunda parte fala da sua pesquisa em limnologia, fazendo...

5-Bromo-2’-deoxyuridine induces visible morphological alteration in the DNA puffs of the anterior salivary gland region of Bradysia hygida (Diptera, Sciaridae)
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: de Almeida,J.C.; Sauaia,H.; Viana,J.C.
5-Bromo-2’-deoxyuridine (BrdUrd) has long been known to interfere with cell differentiation. We found that treatment ofBradysia hygida larvae with BrdUrd during DNA puff anlage formation in the polytene chromosomes of the salivary gland S1 region noticeably affects anlage morphology. However, it does not affect subsequent metamorphosis to the adult stage. The chromatin of the chromosomal sites that would normally form DNA puffs remains very compact and DNA puff expansion does not occur with administration of 4 to 8 mM BrdUrd. Injection of BrdUrd at different ages provoked a gradient of compaction of the DNA puff chromatin, leading to the formation of very small to almost normal puffs. By immunodetection, we show that the analogue is preferentially...

5-HT1A autoreceptor modulation of locomotor activity induced by nitric oxide in the rat dorsal raphe nucleus
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Gualda,L.B.; Martins,G.G.; Müller,B.; Guimarães,F.S.; Oliveira,R.M.W.
The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhibitors produces anxiolytic- and antidepressant-like effects in rats and also induces nonspecific interference with locomotor activity. We investigated the involvement of the 5-HT1A autoreceptor in the locomotor effects induced by NO in the DRN of male Wistar rats (280-310 g, N = 9-10 per group). The NO donor 3-morpholinosylnomine hydrochloride (SIN-1, 150, and 300 nmol) and the NO scavenger...

6 weeks consumption of pure fresh coconut milk caused up-regulation of eNOS and CSE protein expression in middle-aged male rats
Provedor de dados: Brazilian Journal of Pharmaceutical Sciences
Autores: Jansakul,Chaweewan; Naphatthalung,Jomkarn; Pradab,Sakda; Yorsin,Somruedee; Kanokwiroon,Kanyanatt.
Coconut milk (CCM) has been an important cooking ingredient in the Asia-Pacific region since ancient time. Due to its high content of saturated fatty acids, it has been considered atherogenic. We have tested if chronic consumption of fresh coconut milk by middle-aged male rat affects vascular function, plasma glucose and lipid profiles. Compared to control, CCM caused lower maximal contraction to phenylephrine of thoracic aortic rings and increased relaxation to acetylcholine that was abolished by N G-nitro-L-arginine (L-NA) or disruption of the endothelium. DL-propargylglycine caused slight increase in baseline tension of L-NA treated aortic rings of CCM-treated rats and produced higher contractile response of the aortic rings to low concentrations of...

﻿﻿This﻿﻿ study aimed to investigate how 6-bromoindirubin-3’-oxime (BIO) increases the osteogenic differentiation of canine bone mesenchymal stem cells (BMSCs) and the role of the Wnt/β-catenin signaling pathway in this process. We mimicked the effect of Wnt by adding BIO to the culture medium of BMSCs and examined whether canonical Wnt signaling positively affects the differentiation of these cells into osteoblasts. Canine BMSCs were cultured with 0.5 and 1.0 μM BIO under osteogenic conditions and then differentiation markers were investigated. It was found that BIO significantly increased the activity of alkaline phosphatase (ALP), the number of ALP-positive cells, the mineralization level and calcium deposits. Moreover, cells cultured with 0.5 and 1.0 μM...

ABSTRACT 6-Gingerol is the major active constituent of ginger. In the current study, we aimed to investigate the mechanisms underlying the effects of 6-Gingerol on hair growth. Mice were randomly divided into five groups; after hair depilation (day 0), mice were treated with saline, or different concentrations of 6-Gingerol for 11 days. The histomorphological characteristics of the growing hair follicles were examined after hematoxylin and eosin staining. The results indicated that 6-Gingerol significantly suppressed hair growth compared with that in the control group. And choose the concentration of 6-Gingerol at 1 mg/mL to treated with mice. Moreover, 6-Gingerol (1 mg/mL) significantly reduced hair re-growth ratio, hair follicle number, and hair follicle...

-866G/A and Ins/Del polymorphisms in the UCP2 gene and diabetic kidney disease: case-control study and meta-analysis

Abstract Uncoupling protein 2 (UCP2) decreases reactive oxygen species (ROS). ROS overproduction is a key contributor to the pathogenesis of diabetic kidney disease (DKD). Thus, UCP2 polymorphisms are candidate risk factors for DKD; however, their associations with this complication are still inconclusive. Here, we describe a case-control study and a meta-analysis conducted to investigate the association between UCP2 -866G/A and Ins/Del polymorphisms and DKD. The case-control study comprised 385 patients with type 1 diabetes mellitus (T1DM): 223 patients without DKD and 162 with DKD. UCP2 -866G/A (rs659366) and Ins/Del polymorphisms were genotyped by real-time PCR and conventional PCR, respectively. For the meta-analysis, a literature search was conducted...

Parkinson’s disease is a common neurodegenerative disorder. In this study, the monoamine oxidase inhibitory activity and potential anti-parkinsonian effects of 8-propyl-6H-[1,3]dioxolo[4,5-g]chromen-6-one (FCS303), a new synthetic coumarin, were evaluated. To do this, we used the reserpine model of Parkinson’s disease, an assay of levodopa/carbidopa potentiation, the catalepsy model of haloperidol, and an in vitro assay against monoamine oxidase (MAO) activity. Additionally, lipid peroxidation and protein carbonyl group quantification was performed in mice brain homogenates previously treated with haloperidol. FCS303 inhibited monoamine oxidase B (MAO-B) with an IC50 of 5.46 ± 0.36 µM; however, there was no effect on monoamine oxidase A (MAO-A). The oral...

8種類の食用豆類に含まれるポリフェノールと抗酸化活性を比較した。豆類からの連続的な3段階の抽出法は，実験室で次のようにして行った。豆類に温水(50℃)を加え，5時間浸漬(抽出液１)し，その後種皮のみを採取して水を加え，1時間，加熱抽出した(抽出液2)。最後に，加熱抽出後の種皮に5％トリフルオロ酢酸含有のエタノールを加えてさらに1時間，種皮に強く結合しているポリフェノールを加熱抽出した（抽出液３）。全ての抽出液にポリフェノールを含んでいたが，含まれるポリフェノール量は，豆類種実の大小や種皮色との間で相関関係は認められなかった｡アズキおよび赤インゲンマメの抽出液1には，ポリフェノールが多く溶出され，特にアズキの抗酸化活性が最も高かった｡抽出液2にポリフェノールが多く溶出された豆類は，コクリョクトウ，リョクトウ，ソラマメ，赤インゲンマメであり，エンドウやダイズのそれはごく微量であった｡また，抽出液3にポリフェノールを多く含んでいたのは，コクリョクトウ，リョクトウ，クロダイズ，赤インゲンマメ，ソラマメで，種皮に強く結合したポリフェノールを多く含有する豆類といえる｡抽出液1に含まれるポリフェノールの熱安定性とｐH安定性を検討したところ，4時間の加熱を続けても，豆類抽出液の活性低下はほとんど認められなかった。また，ダイズ，エンドウ，アズキ，コクリョクトウ抽出液１（ｐH6.5）の抗酸化活性は，ｐH2.0では同じ～若干上昇したが，ｐH10.0では低下した｡塩基性条件でのアズキとエンドウの活性低下は，特に顕著であった。また，ダイズ，クロダイズおよびリョクトウ抽出液１のβ-カロチン退色抑制能は低かったが，赤インゲンマメ，コクリョクトウ，エンドウ，アズキのそれは高かった。 The antioxidative activities...

(948) Proposal to conserve 4662a Tontelea (Celastraceae) with a conserved type
Provedor de dados: Naturalis Digital Academic Repository
Autores: Mennega, Alberta M.W.
Aublet based Tontelea and its only named species, T. scandens, on material he collected in French Guiana, illustrated as pl. 10 in the original publication. Aublet’s specimens are incorporated in the herbarium of J. J. Rousseau (now located in the Paris Herbarium in herbier Denaiffe) and also in the Herbarium of the British Museum. The sheet in herbier Denaiffe was identified by Lanjouw and Uittien (1940) as the original for Aublet’s pl. 10, which shows a flowering twig, analysis of a flower, and a detached leaf much larger than the leaves on the twig. From a photograph of this sheet it appears that the inflorescence is reproduced only in fragmentary form in the drawing. In the latter the inflorescence is represented as a rather short, few-branched,...

A 1.2 Ma record of glaciation and fluvial discharge from the West European Atlantic margin
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

The correlation of continental sedimentary records with the marine isotope stratigraphy is a challenge of central importance in Quaternary stratigraphy, particularly in Western Europe where long records of glaciation on land areas are particularly rare. Here we demonstrate for the first time the interrelationship of events during the last 1.2 Ma in an ocean-sediment core from the Bay of Biscay (NE Atlantic), SW of the Channel. The identification of discharge variations from tributary river systems to the 'Fleuve Manche' palaeoriver during glacio-eustatic sea-level lowstands demonstrates the correlation of the marine sediment stratigraphy to the expansion and recession of the European ice-sheets. The amplitude and chronology of European ice-sheet...

A 2.14-Myr astronomically tuned record of relative geomagnetic paleointensity from the western Philippine Sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Horng, Cs; Roberts, Ap; Liang, Wt.
We present a 2.14-Myr astronomically tuned relative geomagnetic paleointensity record from the western Philippine Sea. Pseudosingle-domain titanomagnetite is the only magnetic mineral identified and variations in titanomagnetite concentration fall well within the accepted limits for relative paleointensity variations. No significant temporally persistent periodicities are observed in wavelet analyses of the paleointensity time series or in the rock magnetic parameters used for relative paleointensity normalization. This suggests that our paleointensity record is largely free of rock magnetic or lithological artefacts and that it represents a reliable record of geomagnetic behavior with no evidence for modulation of the field at Earth orbital periods. The...

A 2700-year record of ENSO and PDO variability from the Californian margin based on coccolithophore assemblages and calcification
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Beaufort, Luc; Grelaud, Michael.
The El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) account for a large part of modern climate variability. Over the last decades, understanding of these modes of climate variability has increased but prediction in the context of global warming has proven difficult because of the lack of pertinent and reproducible paleodata. Here, we infer the dynamics of these oscillations from fossil assemblage and calcification state of coccolithophore in the Californian margin because El Niño has a strong impact on phytoplankton ecology and PDO on the upwelling intensity and hence on the ocean chemistry. Intense Californian upwelling brings water rich in CO2 and poor in carbonate ions and coccolithophores secrete lower calcified...

A 28-fold increase in secretory protein synthesis is associated with DNA puff activity in the salivary gland of Bradysia hygida (Diptera, Sciaridae)
Provedor de dados: Brazilian Journal of Medical and Biological Research
When the first group of DNA puffs is active in the salivary gland regions S1 and S3 of Bradysia hygida larvae, there is a large increase in the production and secretion of new salivary proteins demonstrable by [3H]-Leu incorporation. The present study shows that protein separation by SDS-PAGE and detection by fluorography demonstrated that these polypeptides range in molecular mass from about 23 to 100 kDa. Furthermore, these proteins were synthesized mainly in the S1 and S3 salivary gland regions where the DNA puffs C7, C5, C4 and B10 are conspicuous, while in the S2 region protein synthesis was very low. Others have shown that the extent of amplification for DNA sequences that code for mRNA in the DNA puffs C4 and B10 was about 22 and 10 times,...

A 2-D section of Ra-228 and Ra-226 in the Northeast Pacific
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Huh, Ca; Ku, Tl.
Seawater samples collected in the northeast Pacific from 112 degrees 50'W to 126 degrees 36'W along a latitudinal band (21-25 degrees N) have been analysed for Ra-228 and Ra-226. Both nuclides exhibit their characteristic distributions. In the surface water, the exponential-like decrease of Ra-228 away from Baja California can be interpreted by horizontal water mixing with eddy diffusion coefficients (K-x) of 1 x 10(6) cm(2) s(-1) and 5 x 10(7) cm(2) s(-1) for scale lengths of 200 km and 1000 km, respectively. In the bottom waters, the decrease of Ra-228 away from bottom sediments can be modeled by vertical eddy diffusivities (K-z) of 15-30 cm(2) s(-1) except at one station (24 degrees 16.9' N, 115 degrees 8.9' W) where a value of 120 cm(2) s(-1) is...

A 2D-QSPR approach to predict blood-brain barrier penetration of drugs acting on the central nervous system
Provedor de dados: Brazilian Journal of Pharmaceutical Sciences
Autores: Sá,Matheus Malta de; Pasqualoto,Kerly Fernanda Mesquita; Rangel-Yagui,Carlota de Oliveira.
Drugs acting on the central nervous system (CNS) have to cross the blood-brain barrier (BBB) in order to perform their pharmacological actions. Passive BBB diffusion can be partially expressed by the blood/brain partition coefficient (logBB). As the experimental evaluation of logBB is time and cost consuming, theoretical methods such as quantitative structure-property relationships (QSPR) can be useful to predict logBB values. In this study, a 2D-QSPR approach was applied to a set of 28 drugs acting on the CNS, using the logBB property as biological data. The best QSPR model [n = 21, r = 0.94 (r² = 0.88), s = 0.28, and Q² = 0.82] presented three molecular descriptors: calculated n-octanol/water partition coefficient (ClogP), polar surface area (PSA), and...

A 37-kb restriction map of the human immunoglobulin lambda variable locus, VB cluster, harboring four functional genes and two non-coding Vl sequences
Provedor de dados: Brazilian Journal of Genetics
Autores: Passos Jr.,Geraldo A.S.; Lefranc,Marie-Paule.
The human immunoglobulin lambda variable locus (IGLV) is mapped at chromosome 22 band q11.1-q11.2. The 30 functional germline v-lambda genes sequenced untill now have been subgrouped into 10 families (V&lt;FONT FACE="Symbol"&gt;l&lt;/font&gt;1 to V&lt;FONT FACE="Symbol"&gt;l&lt;/font&gt;10). The number of V&lt;FONT FACE="Symbol"&gt;l&lt;/font&gt; genes has been estimated at approximately 70. This locus is formed by three gene clusters (VA, VB and VC) that encompass the variable coding genes (V) responsible for the synthesis of lambda-type Ig light chains, and the J&lt;FONT FACE="Symbol"&gt;l&lt;/font&gt;-C&lt;FONT FACE="Symbol"&gt;l&lt;/font&gt; cluster with the joining segments and the constant genes.

A 3D study of the bubble sweep-down phenomenon around a 1/30 scale ship model
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mallat, Bachar; Germain, Gregory; Billard, Jean-yves; Gaurier, Benoit.
The bubble sweep-down phenomenon around oceanographic research vessels generates acoustic disturbances. A specific experimental protocol in a wave and current circulating tank is used to study this phenomenon around a 1/30 scale ship model in a configuration with current, waves and ship motions. 3D visualizations of the bubble clouds and Stereo-PIV (Particle Image Velocimetry) measurements results, both obtained in the bow vicinity of the ship model, are presented in this paper. The behaviour of the breaking wave with bubble generation is studied and the spatial evolution of the bubble clouds is investigated. It is demonstrated that the bubble cloud generation is mainly conditioned by the ascending vertical velocity of the flow near the bow. It is observed...

Cien. Inv. Agr. 41(2):187-196. The Chilean fruit leaf roller Proeulia auraria is a pest of economically important fruit species. Two compounds attractive to males have been identified as (E)-11-tetradecenyl acetate (E11-14:OAc) and (E)-11-tetradecenol (E11-14:OH) and are currently being used in Chile to monitor this species. Preliminary experiments carried out by our group suggested that the 2-compound mixture might not be optimal for the attraction of males, which prompted us to reinvestigate the sex pheromone of P. auraria in the present study. The pheromone...

A 4-years' analysis of the meiofauna community of a dumping site for TiO&lt;sub&gt;2&lt;/sub&gt;-waste off the Dutch coast
Provedor de dados: Open Marine Archive
Autores: Smol, N.; Huys, R.; Vincx, M.
Sublittoral meiofauna of 24 stations was monitored over 4 years (1984-1987) in and around a dumping site for TiO&lt;sup&gt;2-&lt;/sup&gt; acid waste in the Southern Bight of the North Sea off the Dutch coast. The meiofauna was examined quantitatively and qualitatively with special reference to the nematode and the copepod community structure down to species level and to the trophic structure of the nematodes. Biological, sedimentological, geographical parameters and the concentration of several heavy metals were subject to multivariate statistical analysis and classification techniques to evaluate the impact of the TiO&lt;sup&gt;2-&lt;/sup&gt; dumping activities. The meiofauna is dominated by nematodes, copepods, gastrotrichs and turbellarians. There is a...

A 5.3‐million‐year history of monsoonal precipitation in northwestern Australia
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Stuut, Jan‐berend W.; De Deckker, Patrick; Saavedra‐pellitero, Mariem; Bassinot, Franck; Drury, Anna‐joy; Walczak, Maureen H.; Nagashima, Kana; Murayama, Masafumi.
New proxy records from deep‐sea sediment cores from the northwestern continental margin of Western Australian reveal a 5.3 million‐year (Ma) history of aridity and tropical‐monsoon activity in northwestern Australia. Following the warm and dry early Pliocene (~5.3 Ma), the northwestern Australian continent experienced a gradual increase in humidity peaking at about 3.8 Ma with higher than present‐day rainfall. Between 3.8 and about 2.8 Ma, climate became progressively more arid with more rainfall variability. Coinciding with the onset of the northern hemisphere glaciations and the intensification of the northern hemisphere monsoon, aridity continued to increase overall from 2.8 Ma until today, with greater variance in precipitation and an increased...

A 6 year record of baroclinic transport variability of the Antarctic Circumpolar Current at 140 degrees E derived from expendable bathythermograph and altimeter measurements
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rintoul, Sr; Sokolov, S; Church, J.
Repeat hydrographic sections across the Antarctic Circumpolar Current are used to derive an empirical relationship between upper ocean temperature and the baroclinic transport stream function. Cross validation shows this relationship can be used to infer baroclinic transport (above and relative to 2500 dbar) from temperature measurements with an error of a few per cent. The mean transport distribution derived from 31 austral summer expendable bathythermograph (XBT) sections over a 6 year period consists of westward flow immediately south of Tasmania, a broad band of strong eastward flow between 50degrees and 55degreesS, and three cores of eastward flow south of 55degreesS. By defining a second empirical relationship between surface dynamic height and...

A 60 000 year Greenland stratigraphic ice core chronology
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Svensson, A.; Andersen, K. K.; Bigler, M.; Clausen, H. B.; Dahl-jensen, D.; Davies, S. M.; Johnsen, S. J.; Muscheler, R.; Parrenin, F.; Rasmussen, S. O.; Roethlisberger, R.; Seierstad, I.; Steffensen, J. P.; Vinther, B. M.
The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time scale is based on various records from the DYE-3, the GRIP, and the NorthGRIP ice cores, the glacial part is solely based on NorthGRIP records. Here we present an 18 ka extension of the time scale such that GICC05 continuously covers the past 60 ka. The new section of the time scale places the onset of Greenland Interstadial 12 (GI-12) at 46.9 +/- 1.0 ka b2k (before year AD 2000), the North Atlantic Ash Zone II layer in GI-15 at 55.4 +/- 1.2 ka b2k, and the onset of GI-17 at 59.4 +/- 1.3 ka b2k. The error estimates are derived from the accumulated number of uncertain annual...

In order to investigate the possibility of a long-term paleoseismic history from offshore sedimentary records in Sumatra, we collected 144 deep-sea sedi-ment cores in the trench and in lower slope piggyback basins of the Sumatra accretionary prism. We used multibeam bathymetry and seismic reflection data to develop an understanding of catchment basins, turbidity current pathways, and depositional styles, as well as to precisely locate our gravity cores, piston cores, Kasten cores, and multicores. We use detailed physical property data, including computed tomographic X-ray, gamma density, magnetic susceptibility, grain-size analysis, faunal analysis, and smear slides, to evaluate the turbidite stratigraphy and sedimentology at each site. We use radiocarbon...

A 66-kDa protein of bovine hypophyseal Pars tuberalis induces luteinizing hormone release from rat Pars distalis
Provedor de dados: Biocell
Autores: Lafarque,Martha; Oliveros,Liliana.
In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total cell populations, added at a dose of 6 &amp;#956;g per tube, induced the greater LH release from pars distalis cells, without effect on follicle stimulating hormone (FSH) release. After pars tuberalis cells separation on a discontinuos Percoll gradient, only the culture medium of cells from 50 and 60% strength Percoll were able to release LH from rat pars distalis...

A ação dos gens gametofíticos com referência especial ao milho
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Brieger,F. G.
1) The first part deals with the different processes which may complicate Mendelian segregation and which may be classified into three groups, according to BRIEGER (1937b) : a) Instability of genes, b) Abnormal segregation due to distur- bances during the meiotic divisions, c) obscured segregation, after a perfectly normal meiosis, caused by elimination or during the gonophase (gametophyte in higher plants), or during zygophase (sporophyte). Without entering into detail, it is emphasized that all the above mentioned complications in the segregation of some genes may be caused by the action of other genes. Thus in maize, the instability of the Al factor is observed only when the gene dt is presente in the homozygous conditions (RHOADES 1938). In another...

A adição de superfosfato triplo e a percolação de nitrogênio no solo
Provedor de dados: Revista Brasileira de Ciência do Solo
Autores: Mantovani,Analu; Ernani,Paulo Roberto; Sangoi,Luis.
A percolação do N adicionado ao solo na forma amoniacal ou em formas que resultem em NH4+ depende parcialmente da nitrificação porque o NH4+ é adsorvido pelas cargas negativas do solo, enquanto o NO3- permanece na solução do solo. Como a diminuição do pH na zona de aplicação dos fertilizantes pode prejudicar a nitrificação, o presente trabalho objetivou avaliar o efeito da adição de fosfato acidificante junto com adubos nitrogenados na diminuição da percolação de N num solo ácido. O experimento foi realizado em colunas de lixiviação, em 2003, usando-se amostra de um Nitossolo Vermelho com 760 g kg-1 de argila, 40 g kg-1 de matéria orgânica e pH-H2O 4,8. Uréia, sulfato de amônio e nitrato de Ca (150 mg kg-1 N), além de um tratamento sem N, foram combinados...

A adubação do milho em Lavras
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Gomes,F. Pimentel.
O estudo de 38 ensaios de adubação de milho, espalhados em fazendas da Seccional de Lavras, Minas Gerais, Brasil, conduziu às seguintes conclusões: 1. Em experimentos com produção da testemunha abaixo de 2000 Kg/ha houve respostas significativas para N, R, K e calcário. Se tomarmos o preço de 100 kg de milho como equivalente ao de 10 kg de N, 12 de P2O5 ou 30 de K2O, as doses recomendáveis de adubação são: 38 kg/ha de N, zero de P2O5 e 88 kg/ha de K2O. 2. Em experimentos com produção da testemunha não inferior a 2000 kg/ha somente os efeitos de N e de R foram significativos, mas parece preferível usar fertilização completa, que, com os preços adotados, seria recomendável aos níveis de 44kg/ha de N, 75 de P2O5 e 51 de K2O. 3.

Autores: GRISE, M. M.; ALCÂNTARA, P. H. R. de; FREITAS, A. A. de.
Nos últimos anos, houve muita discussão sobre como definir ?agricultura sustentável?. Entretanto, entendeu-se finalmente que agricultura produtiva e sustentável engloba três dimensões da produção: ambiental, econômica e social. No passado, sustentabilidade foi definida principalmente com base em critérios ambientais. Se o solo fosse ruim ou se a água não fosse bem administrada, uma propriedade poderia ser considerada insustentável. Percebeu-se que ser sustentável vai muito além: é indispensável embutir as dimensões econômica e social no conceito, e colocar os produtores no centro do processo. Se uma propriedade não é economicamente sólida ou não é resiliente quando ocorrem choques externos, ou se o bem-estar dos que nela trabalham não é considerado, então...

A Agroecologia como um campo científico.
Provedor de dados: Organic Eprints
Autores: Borsatto, Ricardo Serra; Carmo, Maristela Simões do.
Este texto teórico aborda os desafios de a Agroecologia se consolidar como um campo científico, visto que muitos pesquisadores envolvidos em sua temática requerem para ela o status de Ciência, ao mesmo tempo em que a sua postura epistemológica questiona severamente os paradigmas vigentes no campo científico. Aqui se defende que a Agroecologia pertence também ao campo científico, não negando que ela possa pertencer a outros campos, e que esse pertencimento é estratégico para evitar o seu desvirtuamento. A partir disso remete ao funcionamento dos campos científicos na busca de elementos que auxiliem a Agroecologia a superar as críticas, marginalizações e preconceitos de uma nova ciência que deseja estabelecer os seus novos paradigmas.

Deve-se enfatizar o fato de as empresas paranaenses que compõem o setor agroindustrial canavieiro estarem, desde a desregulamentação setorial, ocorrida em 1990, inseridas no paradigma tecnológico vigente no setor, em que importa estar atento a atributos importantes para a maior competitividade setorial, tais como: maior apuração de custos; introdução de inovação em produtos e processos; e aquisição e construção de competências e habilidades no desenvolvimento de capacitações produtivas, tecnológicas e organizacionais. Como resultados a serem ressaltados pode-se...

A economia brasileira permanece em cenário de recessão, com juros elevados, aceleração da inflação e alta do dólar. Para 2015, a expectativa é o que Índice de Preços ao Consumidor feche o ano em 9,85%, que, se confirmado, representará o maior índice da última década. Os setores de indústria e serviços têm sido os mais afetados, responsáveis pela retração de 2,1% no Produto Interno Bruto (PIB) do segundo trimestre de 2015 em relação ao mesmo período de 2014. Para este ano, o mercado financeiro prevê uma retração de 3,02% no PIB. Se confirmada, será o pior resultado dos últimos 25 anos.

o ambiente semi-árido do Nordeste brasileiro é diversificado nos seus recursos naturais e, complexo na convivência do homem com o seu clima seco e quente. Estudos realizados pela Embrapa Semi-Árido, na década de 70, demonstraram que as prioridades das famílias sertanejas dispersas nesta região, é a garantia de água para beber, água para dessedentação dos animais domésticos e, finalmente; para produção de alimentos. Daí a proposta Pl +2, da Sociedade Civil organizada por' meio da Articulação do Semi-Árido (ASA), a qual congrega mais de mil ONGs. Neste Programa a unidade significa a necessidade de terra para quem ainda não tem, e o "2" se manifesta como duas fontes de água, sendo uma para atender as necessidade de água para consumo humano e a outra para...

Autores: Leite,Rosseval Galdino.
Estudou-se a dieta de 44 exemplares de juvenis de Brycon amazonicum (de 15 a 50mm de C.P), em áreas inundadas da Ilha de Marchantaria, no rio Solimões. Os peixes foram capturados com rede-de-mão com 30cm de diâmetro e cabo de 2 metros de comprimento. As análises foram baseadas em Freqüência de Ocorrência (%) e no número de presas. A dieta foi analisada pelo tamanho (C.P. (mm)) e por data de captura usando uma ANOVA com dois fatores. A data de captura explicou a oscilação no número de presas ingeridas pelos juvenis. A análise qualitativa mostrou poucas mudanças na dieta nesta fase de desenvolvimento. Verificou-se que B. amazonicum apresenta amplo espectro alimentar e que regula o número de presas na dieta de acordo com a disponibilidade dessas presas no...

Diversos parâmetros fornecidos pela análise de solo têm sido usados no Estado de São Paulo para discriminar as respostas à adubação de culturas. Neste trabalho foi avaliada a eficiência desses parâmetros como critério de interpretação, através de estudos de correlação entre resultados de análise de solo e respostas de milho à adubação com nitrogênio, fósforo e potássio em 25 ensaios. Nenhum critério se revelou eficaz para nitrogênio. O teor de fósforo solúvel em H2SO, 0,05N foi eficiente, não tendo havido melhora apreciável das correlações pela consideração dos teores de matéria orgânica, argila ou pH. O teor de potássio trocável revelou-se eficaz, não tendo sido observada melhoria da correlação pela consideração de cálcio e magnésio ou saturação de...

A análise foliar na nutrição do milho: I - Correlação entre analise de fôlhas e produção
Provedor de dados: Bragantia
Autores: Gallo,J. Romano; Hiroce,Rúter; Miranda,Luiz T. de.
Análises de folhas de milho (híbrido H-6999B) foram correlacionadas com as produções em 31 ensaios de adubação em diferentes localidades e solos do Estado de São Paulo. Num total de 24 ensaios para nitrogênio e 26 para o fósforo foram encontradas as correlações: nitrogênio, r = 0,51++, y = - 4,26 + 28,66 x; e fósforo, r =0,47++, y = 43,21 + 160,83 x. As correlações para nitrato não foram consistentes. A omissão de enxofre na presença de NPK resultou em decréscimo variável na produção e no teor de S-S0(4) nas folhas. Com base nos resultados foram estabelecidos os seguintes níveis limiares nas folhas: nitrogênio (N) = 2,90%; fósforo (P) = 0,230%; potássio (K), latossolo roxo = 1,70%; solos podzolizados com cascalho = 2,80%; outros solos = 2,10 a 2,70%.

Provedor de dados: Ciência Rural
Autores: Ernani,Paulo Roberto; Dias,Jaques; Borges,Mário.
Tanto o excesso quanto a deficiência de N causam efeitos negativos na produtividade e na qualidade dos frutos de macieira. Como a taxa de absorção de N pelas árvores de macieira é afetada pela demanda das mesmas, dentro da estação de crescimento, e pelo N disponível no solo, é importante conhecer a necessidade da adição suplementar desse nutriente e a melhor época para aplicá-lo. O presente trabalho objetivou avaliar o efeito da época de aplicação de N ao solo na produtividade de frutos de duas cultivares de macieira. Os experimentos, um para a Gala e outro para a Fuji, foram conduzidos de 1990 a 1996, em Vacaria, RS, num pomar plantado em 1988, na densidade de1481 árvores ha-1, sobre um Latossolo bruno com 4,0% de matéria orgânica, 60% de argila e pH 6,9....

Various ketoreductases exclusively participate in all common biological events, and they are a class of important biocatalysts for the production of chiral alcohols. While many types of ketoreductase have been extensively studied and their functions, properties and utilities have been well known, the capability of stereoselectively reducing two carbonyl groups in the same diketohexanoate ester molecule to form a dihydroxy product by a single ketoreductase has not been evidently characterized. Here we show that a unique and novel enzyme, diketoreductase, was cloned from Acinetobacter baylyi, heterogeneously expressed in _Escherichia coli_ and purified to homogeneity. The diketoreductase is up to 78% homologous to bacterial 3-hydroxyacyl coenzyme-A...

Autores: Barros,   Geraldo Sant'Ana de Camargo; Silva,   Simone Fioritti.
This study aims to analyze the agribusiness contribution to Brazil’s trade balance. A new classification of the agribusiness trade balance was proposed and used to analyze the aspects of the exported products –agricultural products, products of animal origin, industrialized foods and imported inputs – represented by fertilizers. Imports and exports vector autoregression models were used to explain the behavior of these variables. An increase of 1% in the attractiveness – product of the exchange rate by the international prices – boosts immediately the exports of non processed agricultural products by 1.71%, stabilizing at 2% after some trimesters. The attractiveness explains 60 to 74% of the forecast error variances of these exportats. It is noted that an...

A Balaton vízminőségének, a tó állapotának romlása több tényezőre visszave-zethető, hosszú folyamat eredménye. Az egyes tényezők szerepének meghatáro-zása a rendszeres és teljes körű, minden szennyező faktorra kiterjedő mérések hiánya miatt napjainkban is gondot okoz, részben becslésen alapul. Mégis vissza-térő kérdés, hogy a leromlásért melyik ágazat az első számú felelős. A 80-as évek elején a feladatok meghatározásakor a tó vizének tápanyag feldúsulásáért a me-zőgazdaságot kiáltották ki fő felelősnek. Ugyanakkor szakértői vizsgálatok egy-értelműen bizonyították, hogy a Balatonba kerülő hatóanyag maximum 3-5%-a lehet műtrágya eredetű, ami önmagában a vízminőség gyorsütemű romlását nem idézhette elő.

A BAYESIAN ALTERNATIVE TO GENERALIZED CROSS ENTROPY SOLUTIONS FOR UNDERDETERMINED ECONOMETRIC MODELS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Heckelei,   Thomas; Mittelhammer,   Ronald C.; Jansson,   Torbjorn.
This paper presents a Bayesian alternative to Generalized Maximum Entropy (GME) and Generalized Cross Entropy (GCE) methods for deriving solutions to econometric models represented by underdetermined systems of equations. For certain types of econometric model specifications, the Bayesian approach provides fully equivalent results to GME-GCE techniques. However, in its general form, the proposed Bayesian methodology allows a more direct and straightforwardly interpretable formulation of available prior information and can reduce significantly the computational effort involved in finding solutions. The technique can be adapted to provide solutions in situations characterized by either informative or uninformative prior information.

A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
Provedor de dados: Iheringia Série Zoologia
Autores: Montes,Martin M.; Martorelli,Sergio R.
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been studied about the parasite community ecology. From early 2009 to ends of 2010 specimens of J. multidentata were collected from two places, the Salado Relief Channel (S.R.C.) on Samborombón Bay and the Sauce Chico River near to the city of Bahia Blanca (B.B.). All fish were sexed, measured and grouped into sizes/age classes. The fishes from both sites harbored 16 parasitic species: nine digenean, one...

A Bayesian Approach to the Estimation of Environmental Kuznets Curves for CO2 Emissions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mazzanti,   Massimiliano; Musolesi,   Antonio; Zoboli,   Roberto.
This paper investigates the EKC curves for CO2 emissions in a panel of 109 countries during the period 1959-2001. The length of the series makes the application of a heterogeneous estimator suitable from an econometric point of view. The results, based on the hierarchical Bayes estimator, show that different EKC dynamics are associated with the different sub samples of countries considered. On average, more industrialized countries show an EKC evidence in quadratic specifications, which are nevertheless probably evolving into an N shape, emerging from cubic specifications. Less developed countries consistently show that CO2 emissions still rise positively with income, though some signals of an EKC path arise.

A Bayesian approach towards facilitating climate change adaptation research on the South African agricultural sector
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musango,   J.K.; Peter,   C.
Evaluating the range of proposed adaptation measures to combat the sensitivity of agriculture to climate change effects involves evaluating complex interactions between human and natural systems. Integrated strategy-making and implementation in the agricultural sector to reduce the risks posed by climate change requires the consideration of multiple, interdisciplinary factors and the sensitivities of their inter-relationships. Lack of information on the sensitivity of agricultural activities to climate change in Africa hampers climate change adaptation research on the region. In water scarce South Africa, the growth of the agricultural sector is threatened by projected decreases in water availability due to climate change. This paper shows how Bayesian...

Understanding the specific relationships between ecological and socioeconomic conditions and marine tenure is likely to contribute to successful functioning of self-governance institutions for common-pool resources. Complex interrelationships of factors influencing fishing activities of coastal communities and implementation of customary marine tenure over their waters can be represented in a Bayesian belief network model. We developed a Bayesian belief network model that includes the links between factors for fishing communities in the Kei Islands in Indonesia, based on indepth local surveys. Our results showed that the cumulative impacts of multiple factors on key social, economic, and environmental outcomes can be much larger than the impact from a...

A Bayesian Belief Network to Infer Incentive Mechanisms to Reduce Antibiotic Use in Livestock Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ge,   Lan; Van Asseldonk,   Marcel A.P.M.; Valeeva,   Natasha I.; Hennen,   Wil; Bergevoet,   Ron H.M.
Efficient policy intervention to reduce antibiotic use in livestock production requires knowledge about the rationale underlying antibiotic usage. Animal health status and management quality are considered the two most important factors that influence farmers’ decision-making concerning antibiotic use. Information on these two factors is therefore crucial in designing incentive mechanisms. In this paper, a Bayesian belief network (BBN) is built to represent the knowledge on how these factors can directly and indirectly determine antibiotic use and the possible impact on economic incentives. Since both factors are not directly observable (i.e. latent), they are inferred from measurable variables (i.e. manifest variables) which are influenced by these...

A Bayesian state-space model to estimate population biomass with catch and limited survey data: application to the thornback ray (Raja clavata) in the Bay of Biscay
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Marandel, Florianne; Lorance, Pascal; Trenkel, Verena M.
The thornback ray (Raja clavata) in the Bay of Biscay is presumed to have declined during the 20th Century. To evaluate this decline and estimate biomass trajectories, a hypothetical catch time series was created for the period 1903-2013. A Bayesian state-space biomass production model with a Schaefer production function was fitted to the hypothetical catch time series and to a shorter research vessel Catch Per Unit Eeffort (CPUE) time series (1973-2013, with missing years). A censored likelihood made it possible to obtain biomass estimates without a CPUE time series or only with an estimate of biomass depletion. A simulation-estimation approach showed a high sensitivity of results to the prior for the intrinsic growth rate. The model provided biomass...

A Bayesian Total Factor Productivity Analysis of Tropical Agricultural Systems in Central-Western Africa And South-East Asia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tonini,   Axel; Matus,   Silvia Saravia; Gomez y Paloma,   Sergio.
This paper computes and analyses total factor productivity (TFP) growth rates for tropical agricultural systems in Central-Western Africa and South-East Asia. Two regions that despite sharing common agro-ecological conditions, have pursued different adoption rates of green revolution technology and have reported dissimilar yields per hectare. A panel data set is constructed for the period 1987-2007 from the FAOSTAT database. A Bayesian stochastic frontier model with country specific temporal variation in technical efficiency is estimated. Technical efficiency estimates reveal that there is substantial room for improvement in both continental sub-sets and that TFP estimates show on average larger rates of growth for South-East Asian countries as compared to...

A BEHAVIORAL APPROACH TOWARDS FUTURES CONTRACT USAGE.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pennings,   Joost M.E.; Leuthold,   Raymond M.
We propose a behavioral decision-making model to investigate what factors, observable as well as unobservable, owner-managers consider regarding futures contract usage. The conceptual model consists of two phases, reflecting the two-stage decision structure of manager’s use of futures. In the first phase owner-managers consider whether futures are within the market choice set for the enterprise. In the second phase the owner-manager decides whether or not to initiate a futures position when confronted with a concrete choice situation. In both phases owner-manager’s beliefs and perceptions play an important role. The proposed model is tested on a data set of Dutch farmers, based on computer-assisted personal interviews. Because we incorporate latent...

A benthic Si mass balance on the Congo margin: Origin of the 4000 m DSi anomaly and implications for the transfer of Si from land to ocean
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ragueneau, O.; Regaudie-de-gioux, A.; Moriceau, B.; Gallinari, M.; Vangriesheim, Annick; Baurand, F.; Khripounoff, Alexis.
To elucidate the origin of the silicic acid (DSi) anomaly observed along the 4000 isobath on the Congo margin, we have established a benthic Si mass balance and performed direct measurements of biogenic silica (bSiO(2)) dissolution in the deep waters and in the sediments. Results strongly suggest that the anomaly originates from the sediments; the intensity of DSi recycling is consistent with the degradation of organic matter, as observed from Si:O-2 ratios in the benthic fluxes compared to that ratio observed in the anomalies. Strong imbalances, observed in both the Si and C mass balances, suggest that the biogenic matter that degrades and dissolves in these sediments near 4000 m does not come from pelagic sedimentation. It is probably not coming also...

A Better Approach to Resolving Variable Selection Uncertainty in Meta Analysis for Benefits Transfer
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Randall,   Alan; Chen,   Ding-Rong.
Because original high-quality non-market valuation studies can be expensive, perhaps prohibitively so, benefits transfer (BT) approaches are often used for valuing, e.g., the outputs of multifunctional agriculture. Here we focus on the use of BT functions, a preferred method, and address an under-appreciated problem – variable selection uncertainty – and demonstrate a conceptually superior method of resolving it. We show that the standard method of value-function BT, using the full estimated model, may generate BT values that are too sensitive to insignificant variables, whereas models reduced by backward elimination of insignificant variables pay no attention to insignificant variables that may in fact have some influence on values. Rather than searching...

A Bibliography of Pelagic Tunicates
Provedor de dados: Naturalis Digital Academic Repository
Autores: Waard-Pouw, G. van; Soest, R.W.M. van.
The present bibliography on pelagic Tunicates has been compiled over a period of 4 years, mainly by the first author. It is meant, not as an official publication, but as a working aid for students of pelagic Tunicates. It comprises about 1300-1400 different titles of books and articles. For obvious reasons the mere listing of all those titles in alphabetical order would be impractical for specialized demands. Splitting this list in as many subheadings as possible in a way like the Zoological Record would be ideal. However, many articles and books are difficult to place under one heading; the same titles would have to be mentioned under a number of different headings. With as many headings as possible this would mean a multiplication of the 1300-1400 titles...

A Binary Logit Analysis of Factors Impacting Adoption of Genetically Modified Cotton
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Banerjee,   Swagata (Ban); Martin,   Steven W.
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.

Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

A Binomial Tree Approach to Valuing Fixed Rotation Forests and Flexible Rotation Forests Under a Mean Reverting Timber Price Process
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tee,   James; Scarpa,   Riccardo; Marsh,   Dan; Guthrie,   Graeme.
NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age. Under a stochastic timber price process, it has been shown that the valuation of a flexible rotation forest is equal or higher than that of a fixed rotation forest, because a flexible harvest regime delays the harvest if the timber price is not favourable, whereas a fixed harvest regime would proceed to harvest regardless of the price. Often, valuation of fixed and flexible rotation ages are compared using 2 different methods – NPV (or LEV) and Real Options. The...

A biodegradation study of forest biomass by Aspergillus niger F7: correlation between enzymatic activity, hydrolytic percentage and biodegradation index
Provedor de dados: Brazilian Journal of Microbiology
Autores: Sharma,Nivedita; Kaushal,Richa; Gupta,Rakesh; Kumar,Sanjeev.
Aspergillus niger F7 isolated from soil was found to be the potent producer of cellulase and xylanase. The residue of forest species Toona ciliata, Celtris australis, Cedrus deodara and Pinus roxburghii was selected as substrate for biodegradation study due to its easy availability and wide use in industry. It was subjected to alkali (sodium hydroxide) treatment for enhancing its degradation. Biodegradation of forest waste by hydrolytic enzymes (cellulase and xylanase) secreted by A. niger under solid state fermentation (SSF) was explored. SSF of pretreated forest biomass was found to be superior over untreated forest biomass. Highest extracellular enzyme activity of 2201±23.91 U/g by A. niger was shown in pretreated C. australis wood resulting in...

The purpose of the present study was to investigate the biodistribution profile of the venom of Hemiscorpius lepturus, the most dangerous scorpion in Iran. Blood and tissue samples were taken at various predetermined intervals during a 400-minute period for the venom and a 360-minute period for the antivenom in rats. The radio-iodination was carried out using the chloramine-T method. The results showed that the descending order of venom uptake was skin, kidneys and intestine, respectively. The descending order of polyclonal antivenom uptake was kidneys, intestine, heart and lungs. The calculated pharmacokinetic parameters of the venom were Telimination half-life = 521.5 ± 12.6 minutes; Vd/F (apparent volume of distribution) = 14.9 ± 3.3 mL; clearance...

A bioeconomic analysis of the impact of decommissioning programs: Application to a limited-entry french scallop fishery
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guyader, Olivier; Daures, Fabienne; Fifas, Spyros.
The objective of this paper is to assess the benefits and costs of decommissioning policies aimed at reducing fleet capacity through premiums offered by the public authority to fishermen to scrap their vessels. A case study, the limited entry scallop fishery of the Saint Brieuc Bay, France, is used to con- sider the problem of excess capacity and to model the bioeconomic consequences of disinvestment behavior. Special attention is paid to the assessment of fishermen's willingness to leave the fishery and to the implementation of public policy in terms of budget level and premiums offered to the fishermen. Spreadsheet simulations show that the impact of decommissioning programs is positive in terms of net surplus, even in the case of increasing technical...

A Bio-Economic Assessment of the West Coast Deep-Sea Hake Fishery with Referede to the Optimal Utitlization and Management of the Resource.
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Hutton, T.; Sumaila, U.R.
The cooperative versus non-cooperative management of the South African west coast hake stock is explored using game theoretic modelling in conjunction with an age-structured model. The age-structured model is used to produce a physical flow account for input into national resource accounts. Between 1989 and 1998, the average catch of hake on the west coast was 92000 tons, most of which was harvested by the demersal trawl sector. The physical flow account indicates that the conservative re-building management strategy pursued for the fishery over the same time period mentioned above, has resulted in a 29% increase in the demersal trawl catch over the last decade. We simulated the effects of alternative quota restrictions on two fishing sectors (the...

Autores: Olson,   Kent D.; Badibanga,   Thaddee Mutumba.
Since its first detection in the North Central region in July 2000, the soybean aphid (Aphis glycines Matsamura) has caused considerable loss in soybean (Glycine max L.) yield, bean quality, and producer income.  Discovered first in Wisconsin and then in adjoining states, it is currently distributed in 21 US states and parts of Canada. In 2003, over 42 million acres of soybean in the North Central US were infested and over 7 million acres were treated with insecticides to control soybean aphid (Landis et al. 2003). Populations exceeding 24,000 aphids per plant and 40% losses in seed yield have been reported (DiFonzo &amp; Hines 2002).

Autores: Overnell, J; Harvey, Sm; Parkes, Rj.
The sediments of the upper basins of Lochs Goil, Fyne and Etive were high in both solid phase extractable manganese (up to 3.7% w/w), and high in pore water manganese (up to 600 mu M), while Loch Linnhe sediments were low in manganese. Solid phase manganese from the surface sediments at the deepest stations was highest in those lochs where the mean residence time of the bottom water is longest, indicating the importance of manganese cycling through the water column. Porewater iron concentrations in the top 2 cm of sediment were highest near the heads of the lochs, i.e. near the main freshwater inputs. Within sediments of Lochs Goil, Fyne and Etive high rates of total sulphate reduction were associated with high relative rates of formation of acid volatile...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Zhu,Wen-Yi; Zang,Lei; Li,Jian; Guan,Li; Hai,Yong.
Posterior long-segment spinal fusion may lead to proximal junctional kyphosis (PJK). The present study sought to identify the appropriate fusion levels required in order to prevent PJK using finite element analysis. A finite element model was constructed based on the whole-spine computed tomography findings of a healthy adult. Nine commonly used posterior spinal fusion methods were selected. Stress on the annulus fibrosis fibers, the posterior ligamentous complex, and the vertebrae after various spinal fusions in the upright position were compared. This study was divided into two groups: non-fusion and fusion. In the former, the stress between the T10 and the upper thoracic vertebrae was higher. Comparing thoracic and lumbar segments in the fusion group,...

A biomolecular proportional integral controller based on feedback regulations of protein level and activity
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mairet, Francis.
Homeostasis is the capacity of living organisms to keep internal conditions regulated at a constant level, despite environmental fluctuations. Integral feedback control is known to play a key role in this behaviour. Here, I show that a feedback system involving transcriptional and post-translational regulations of the same executor protein acts as a proportional integral (PI) controller, leading to enhanced transient performances in comparison with a classical integral loop. Such a biomolecular controller-which I call a level and activity-PI controller (LA-PI)-is involved in the regulation of ammonium uptake by Escherichia coli through the transporter AmtB. The P-II molecules, which reflect the nitrogen status of the cell, inhibit both the production of...

The properties of poly(4-aminophenol) modified graphite electrode as material for the immobilization of acetylcholinesterase were investigated by the Cyclic Voltammetry, Electrochemical Impedance Spectroscopy and Atomic Force Microscopy. The polymer was deposited on graphite electrode surface by the oxidation of 4-aminophenol and then acetylcholinesterase was immobilized on the surface of the electrode. The biosensor coupled in the continuous flow system was employed for the detection of dichlorvos. The detection and quantification limits were 0.8 and 2.4 μmol L-1 dichlorvos, respectively. Graphite electrodes modified with the poly(4-aminophenol) showed to be an efficient and promising material for immobilization of acetylcholinesterase enzyme. The...

A Biosystematic Study of Nipponolejeunea Hatt. (Hepaticae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Inoue, Hiroshi; Asakawa, Yoshinori; Gradstein, S. Rob.
The genus Nipponolejeunea Hattori was established by Hattori (1944) based on Pycnolejemea pilifera Steph. from Japan. Its primary important generic characters include 1) the two gynoecial innovations, 2) the triplicate perianth, and 3) the long cilia on leaf- and underleaf-margin. Hattori (1944) also assigned Pycnolejeunea subalpina Horik. to Nipponolejeunea, thus admitting two Japanese species in that genus. Since then, the genus Nipponolejeunea has been repeatedly discussed, especially by Mizutani (1961) and Schuster (1963) from taxonomic points of view.

Proteases hydrolyze the peptide bonds of proteins into peptides and amino acids, being found in all living organisms, and are essential for cell growth and differentiation. Proteolytic enzymes have potential application in a wide number of industrial processes such as food, laundry detergent and pharmaceutical. Proteases from microbial sources have dominated applications in industrial sectors. Fungal proteases are used for hydrolyzing protein and other components of soy beans and wheat in soy sauce production. Proteases can be produced in large quantities in a short time by established methods of fermentation. The parameters such as variation in C/N ratio, presence of some sugars, besides several other physical factors are important in the development of...

A BIOTIC CONTROL PERSPECTIVE ON NITRATE CONTAMINATION OF GROUNDWATER FROM AGRICULTURAL PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erickson,   Jon D.; Schlapfer,   Felix.
Agronomists consider the continuity and nutrient capturing properties of cover crops as important determinants of nutrient cycling in agricultural systems.  Managing for these biotic control functions can help limit nutrient loss and groundwater contamination between main crop harvests.  This simulation study highlights the potential role of cover crop management in a welfare economics framework.  The objective is to find the optimal combination of nutrient input to the main crop, the extent of off-season cover crops, and crop functional diversity to maximize the sum of benefits from agricultural production and groundwater protection.

A transferência de embriões (TE) já vem sendo utilizada em eqüinos há pelo menos duas décadas, sempre a partir de ovulação simples. Para aumentar a eficiência reprodutiva, este estudo avaliou a bipartição embrionária como uma alternativa para melhorar os índices de gestação na transferência de embriões em eqüinos. Foram utilizadas 21 éguas de diferentes padrões raciais, com idade variando entre 4 e 15 anos de idade, pesando entre 270 a 480kg. A partir da identificação do cio (rufiação), os animais foram monitorados através de exames ultra-sonográficos trans-retais até o momento da ovulação, sendo as receptoras, uma vez ao dia e as doadoras três vezes ao dia. As receptoras utilizadas ovularam um dia antes ou até três dias depois das doadoras. As doadoras...

A bovine herpesvirus 5 recombinant defective in the thymidine kinase (TK) gene and a double mutant lacking TK and the glycoprotein E gene are fully attenuated for rabbits
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Silva,S.C.; Brum,M.C.S.; Weiblen,R.; Flores,E.F.; Chowdhury,S.I.
Bovine herpesvirus 5 (BoHV-5), the agent of herpetic meningoencephalitis in cattle, is an important pathogen of cattle in South America and several efforts have been made to produce safer and more effective vaccines. In the present study, we investigated in rabbits the virulence of three recombinant viruses constructed from a neurovirulent Brazilian BoHV-5 strain (SV507/99). The recombinants are defective in glycoprotein E (BoHV-5gEΔ), thymidine kinase (BoHV-5TKΔ) and both proteins (BoHV-5gEΔTKΔ). Rabbits inoculated with the parental virus (N = 8) developed neurological disease and died or were euthanized in extremis between days 7 and 13 post-infection (pi). Infectivity was detected in several areas of their brains. Three of 8 rabbits inoculated with the...

Provedor de dados: Open Marine Archive
Autores: Baeyens, W.F.J.; Monteny, F.; Van Ryssen, R.; Leermakers, M.
The behaviour of Cu, Zn, Cd, and Pb in the Scheldt estuary was investigated in the periods 1981 to 1993 and 1995. The Hg behaviour was studied between 1992 and 1994. A box model was used to establish the relationship between the trace metal inputs and the fate of these pollutants in the Scheldt estuary. Annual budgets were calculated for particulate and dissolved trace metals. For Hg, seasonal budgets of the various species (inorganic Hg, methylmercury, Hg°) could also be calculated. These budgets allow an evaluation of the consistency of each individual flux or process, such as the inputs of the various metals into the North Sea, the sedimentation flux of particulate metals in the area of high turbidity, the evasional fluxes and the formation rates of...

A brain microdialysis study on 5-HT release in freely moving rat lines selectively bred for differential 5-HT1A receptor function
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Gonzalez,L.E.; Parada,M.A.; Tucci,S.; Teneud,L.; Overstreet,D.H.; Hernandez,L.
Breeding for high and low hypothermic responses to systemic administration of a serotonin1A (5-HT1A) receptor agonist (8-hydroxy-2-(di-n-propylamino)tetralin, 8-OH-DPAT) has resulted in high DPAT-sensitive (HDS) and low DPAT-sensitive (LDS) lines of rats, respectively. These lines also differ in several behavioral measures associated with stress. In the present microdialysis study we observed that basal 5-HT concentrations in the prefrontal cortex and dorsal hippocampus did not differ significantly between HDS and LDS rats. Thus, behavioral differences between the HDS and LDS lines might not be attributed to differences in basal 5-HT release. However, both lines had lower basal levels of 5-HT release than their randomly bred control group (random...

The control of the major sugarcane pest, Diatraea saccharalis, is limited by the stem location of the caterpillar. As part of a long-term project towards the development of an alternative and efficient delivery system of Cry proteins to control the sugarcane borer, the current work describes the selection and characterization of a Brazilian B. thuringiensis strain with prominent activity towards D. saccharalis. Strain S76 was eleven-fold more active than the HD-1 Lepidoptera-standard strain, as estimated by the LC50 of 13.06 µg/L and 143.88 µg/L, respectively. We observed bipiramidal and cuboidal crystals similar to those found in other B. thuringiensis strains with entomopathogenic activity against Lepidoptera and Diptera. In addition, smaller and...

A Brief Summary of U.S. Farm Program Provisions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Richardson,   James W.; Anderson,   David P.; Outlaw,   Joe L.; Campiche,   Jody L.
This publication began as a need for a short summary of farm programs and farm bills for two agricultural economics courses focusing on agricultural policy -- ag. economics 429, and ag. economics 614. Over time, it became clear that many students taking these courses had less and less background in agriculture and less (even cursory) knowledge of policies than those of the recent past. After this list was developed, a number of other professional agricultural economists found copies and began to use it, hence its publication in a more structured form. The list of Farm Program Provisions is not all-inclusive. It certainly does not contain all the laws and provisions that have affected agriculture over the years. However, it is an easy reference to farm...

A budget of carbon cycling in the Belgian coastal zone: relative roles of zooplankton, bacterioplankton and benthos in the utilization of primary production
Provedor de dados: Open Marine Archive
Autores: Joiris, C.R.; Billen, G.; Lancelot, MH.; Daro, M.H.; Mommaerts, J.-P.; Bertels, A.; Bossicart, M.; Nijs, J.; Hecq, J.H.
The various biological compartments of the Belgian coastal zone of the North Sea were studied since 1971. The synthesis of available data on carbon cycling includes phytoplankton biomass and activities (particulate and dissolved primary production, respiration) , zooplankton biomass and activities (grazing, respiration) and planktonic and benthic microbial heterotrophic activities. These various carbon flux estimates allow the development of an overall budget of carbon cycling. This budget shows the importance of microbial (planktonic and benthic) heterotrophs versus zooplankton in the utilization of primary production. Comparison with literature data suggests that this could be a general feature of coastal, as opposed to open sea ecosystems.

Autores: Sefton,   Clive A.; Cox,   Rodney J.
This paper presents an evaluation of a farm-business assessment model that uses financial performance measures and tracks ‘wealth change’ to evaluate performance trends over time, and ranks the relative business performance of commercial participants. Its core component involves the use of comparative analysis, which is structured as an introductory rapid-assessment model, together with a ranking system that has been designed to differentiate the relative performance levels of farm businesses. The system has been labelled as the Business Performance Index (BPI) model to reflect its performance-ranking role that explores the relationships, if any, between farmer attitudes and business performance. The BPI model is discussed within the context of the debate...

Autores: Mengel,Alex Alexandre; Aquino,Silvia Lima de.
O artigo analisa os conflitos existentes na cadeia produtiva do tabaco no Brasil e as estratégias historicamente estabelecidas por cada agente. Para tanto, interpretamos a cadeia produtiva do tabaco como um campo de disputas. Como ferramentas metodológicas realizamos revisão bibliográfica e entrevistas semiestruturadas. Dentre os resultados, constatamos que, em geral, os agentes do campo tabagista assumem três tipos de estratégias: 1) a defesa do campo; 2) posições estratégicas intermediárias ponderando disputas históricas que consideram posições conflituosas no campo; 3) posições contrárias ao próprio campo do tabaco

A Calibrate Auction-conjoint Experiment to Elicit Consumer Valuation of Sustainable Farming: Is Agro-systems Preservation Relevant?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Avitia,   Jessica; Costa-Font,   Montserrat; Gil,   Jose Maria; Lusk,   Jayson L.
This paper analyses the role of agro-systems preservation on making food choices. It employs the “Calibrate Auction-Conjoint Valuation method” (CACM), which relates hypothetical conjoint valuation of product attributes with real market behavior using real economic incentives. The paper also allows comparing the hypothetical and nonhypothetical valuations in order to value the difference between the theoretic and the incentive-compatible WTP for a same respondent and within a single experiment. Thus the paper aims at testing for: 1) the internal consistency on people’s behavior towards sustainable agriculture, and 2) the relevance of the price attribute versus agro-ecosystems preservation for a fresh product. Results suggest that Spanish respondents’...

Irrigated agriculture is the largest water user in many regions, and agricultural water use efficiency and consumption has been studied by several authors. This paper provides a framework and application of economic valuation of water for agriculture in three regions in northern Baja California, Mexico, namely Guadalupe, Maneadero and Mexicali Valleys. Positive mathematical programming (PMP), a deductive valuation technique, was the framework used for this estimation using water delivery data reported by the National Water Commission in Mexicali, production costs and cultivated area, production factors use from the Agriculture Ministry (SAGARPA); and other data from previous studies. Analysis of the results shows that marginal economic water value in...

Autores: Whitby, Hannah; Planquette, Helene; Cassar, Nicolas; Bucciarelli, Eva; Osburn, Christopher L.; Janssen, David J.; Cullen, Jay T.; González, Aridane G.; Völker, Christoph; Sarthou, Geraldine.
Primary production by phytoplankton represents a major pathway whereby atmospheric CO2 is sequestered in the ocean, but this requires iron, which is in scarce supply. As over 99% of iron is complexed to organic ligands, which increase iron solubility and microbial availability, understanding the processes governing ligand dynamics is of fundamental importance. Ligands within humic-like substances have long been considered important for iron complexation, but their role has never been explained in an oceanographically consistent manner. Here we show iron co-varying with electroactive humic substances at multiple open ocean sites, with the ratio of iron to humics increasing with depth. Our results agree with humic ligands composing a large fraction of the...

Autores: KADOHIRA, Mutsuyo; TAJIMA, Motoshi; 門平, 睦代.
The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not...

A Case of Anomalous Horizontal Fissure and Hypoplastic Middle Lobe of the Right Lung
Provedor de dados: International Journal of Morphology
Autores: Okamoto,Keishi; Wakebe,Tetsuaki; Saiki,Kazunobu; Manabe,Yoshitaka; Tsurumoto,Toshiyuki.
During dissection practice for medical students at Nagasaki University, a horizontal fissure and hypoplastic middle lobe were encountered in the right lung of an 81-year-old Japanese female. In a normal right lung, the horizontal fissure is situated anterior to the oblique fissure. On the contrary, in the present case, the horizontal fissure was situated posterior to the oblique fissure. We identified a small, additional lobe on the medial surface of this lung. It was situated in the medial part of the oblique fissure, and was determined to be a small hypoplastic middle lobe. As a result of the hypoplasia of the middle lobe, the original horizontal fissure may have disappeared from the anterior surface. The horizontal fissure, in this case, may be a...

A case of intersex occurrence in Steindachneridion parahybae (Steindachner, 1877) (Siluriformes: Pimelodidae) under captivity condition: a cytogenetic and morphological study
Provedor de dados: Neotropical Ichthyology
Autores: Honji,Renato M.; Caneppele,Danilo; Pandolfi,Matias; Nostro,Fabiana L. Lo; Moreira,Renata G.
ABSTRACT Little is known about reproductive biology of endangered Steindachneridion parahybae , a gonochoristic teleost species inhabiting the Paraíba do Sul River Basin, and herein is the first description of intersex in S. parahybae juvenile. The normal appearance of ovaries and testes in juvenile from the same lot of breeding were also described for comparison, even as cytogenetic analysis was performed in these juveniles. One specimen was a priori classified as female due to the macroscopic characteristic of ovaries, with small yellow oocytes, without fringes (a main characteristic of catfish male), and larger than testes; however the microscopic analysis revealed the presence of ovotestes, including the complete spermatogenesis. S. parahybae had...

A case of prenatal diagnosis of fetal hydantoin syndrome by ultrasound
Provedor de dados: Genetics and Molecular Biology
Autores: Gollop,Thomaz Rafael; Salzo,Ivan.
Fetal hydantoin syndrome (FHS) is a set of disruptions occasionally present in fetuses exposed in utero to phenytoin or other anticonvulsants. Administration of phenytoin in early pregnancy may impair proper psychomotor performance expected for children's development. Several combined phenotypic markers delineate the syndrome, but the presence of single clinical signs is more common. There is controversy about the etiology of FHS. Associated disruptions may be related to a deficiency in a detoxifying enzyme (epoxide hydrolase), vascular problems, and/or factors not yet known. Genetic causes are believed to influence susceptibility to the drug. This text reports an unusual pattern of malformations detected in an ultrasound scan (gastroschisis, sacral...

A case of urinary tract infection caused by Raoultella planticola after a urodynamic study
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Tuğcu,Murat; Ruhi,Caglar; Gokce,Ali M.; Kara,Melih; Aksaray,Sebahat.
Abstract Here we report the case of a patient who developed urinary tract infection after a urodynamic study. The causative agent was Raoultella planticola, a rare opportunistic pathogen that usually invades immunocompromised patients. While a urinary tract infection with R. planticola has been previously described, this is the first report in which an R. planticola infection developed after a urodynamic study. We postulate that the mechanism of infection was direct invasion of the urinary tract from contaminated urodynamic study equipment. Here, we discuss the role played by isotonic solutions in facilitating bacterial reproduction.

A Case Study of an NGOs Ecotourism Efforts: Findings Based on a Survey of Visitors to its Tropical Nature Reserve
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tisdell,   Clement A.
This article outlines the efforts of a small NGO, the Mareeba Wetland Foundation, to conserve nature and conduct tourism at its Mareeba Tropical Savanna Wetland Reserve in northern Queensland. It provides background about the establishment of the reserve and its nature and draws on the results from a survey of visitors to this reserve. It provides a socio-economic profile of visitors, their frequency of visits to it and their knowledge of it prior to visiting. This knowledge is found, on the whole, to be poor. The way in which visitors decided to visit the reserve is also considered as are indicators of the economic surplus obtained from visits. Because for most visitors their visit was an experiential good, doubts are raised about the traditional method...

Autores: Jong, C. de.
After Mr. F. T. Valck Lucassen's decease in september 1939 his collections have been transported to the Leiden Museum for better preservation. In 1941 the Rijksmuseum van Natuurlijke Historie, Leiden, could acquire these considerable collections which also included those of Janson (London) and Girard (Geneva). These collections contain a great number of species, often represented by the types or series of types, many of which described by Valck Lucassen himself. In an obituary Uyttenboogaart (1940: 1-2) gave an enumeration of all papers by Valck Lucassen, most of which are on Cetonids. The monograph on the genus Lomaptera, announced by Uyttenboogaart, had to be translated, illustrated and to be made ready for printing; it was published in 1961 by the...

A C-Band Geophysical Model Function for Determining Coastal Wind Speed Using Synthetic Aperture Radar
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lu, Yiru; Zhang, Biao; Perrie, William; Mouche, Alexis; Li, Xiaofeng; Wang, He.
A new geophysical model function (GMF), called C_SARMOD2, has been developed to relate high-resolution C-band normalized radar cross section (NRCS), acquired in VV polarization over the ocean, to the 10-m height wind speed. A total of 3078 RADARSAT-2 and Sentinel-1A VV-polarized synthetic aperture radar (SAR) images, acquired under different wind speed conditions, were collocated with in situ buoy measurements. The paired dataset was used to derive transfer functions and coefficients of C_SARMOD2, and then to validate the wind speed retrievals. The comparison between SAR-retrieved wind speeds and buoy measurements show almost no bias and a root mean square error of 1.84 m/s. Two representative quad-and dual-polarization SAR images, acquired from coastal...

I am the first to agree with Alston in this statement. I am much indebted to Mr. Alston for his minute description of the Mus in question, s. n. Mus terrae-reginae. If I had known that Gray’s leucopus has the tail shorter than head and body and the fur above dark reddishand not greyish-brown, I should certainly not have made a mistake in confounding these two distinct species. But I believe it quite impossible to recognize species if they are described so incompletely and inexactly as is the case with the greater part of Gray’s...

A census of Meddies in a long-term high-resolution simulation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Barbosa Aguiar, Ana Claudia; Peliz, Alvaro; Carton, Xavier.
The output from a high-resolution two-decade long Mediterranean Outflow simulation is analysed here to provide a census of Mediterranean Water eddies (aka Meddies), both anticyclones and cyclones. The formation rate of Meddies that survive for at least 90 days is of 12 Meddies yr(-1) of which similar to 12% are cyclones. The rate of formation reaches 40 Meddies yr(-1) (30% cyclones) when considering all the Meddies living over 15 days. About 70% of the population is born along the southwestern Iberian slope, but several robust Meddles also originate in points of convergence of the main pathways into the open ocean. The longest-lived Meddies propagate northwestwards, but most of the anticyclones veer southwestwards after a while. As the Meddies drift away...

A characterization of Chilean farmers based on their market-production orientation
Provedor de dados: Ciencia e Investigación Agraria, Revista Latinoamericana en Ciencias de la Agricultura
Autores: Echeverría,Rodrigo; Moreira,Víctor; Barrena,José; Gopinath,Munisamy.
Chile's open trade policy, implemented during the last few decades, has greatly transformed Chilean farmers and their production systems. As a result, farmers can be grouped into three categories based on their market-production orientation: domestic, transitional or export producers. The objective of this paper is to analyze the factors underlying the decision to produce for a particular market and compare the three groups of farmers based on data from the 2007 agricultural census. A generalized ordered logit model was used to analyze different methods of production, and non-parametric methods were used to compare the groups. Results show that some farmers change categories in sequence; farmers that produce for the domestic market can later produce for...

Immunoglobulin G (IgG) of excellent quality for intravenous use was obtained from the cryosupernatant of human plasma by a chromatographic method based on a mixture of ion-exchange, DEAE-Sepharose FF and arginine Sepharose 4B affinity chromatography and a final purification step by Sephacryl S-300 HR gel filtration. The yield of 10 experimental batches produced was 3.5 g IgG per liter of plasma. A solvent/detergent combination of 1% Tri (n-butyl) phosphate and 1% Triton X-100 was used to inactivate lipid-coated viruses. Analysis of the final product (5% liquid IgG) based on the mean for 10 batches showed 94% monomers, 5.5% dimers and 0.5% polymers and aggregates. Anticomplementary activity was 0.3 CH50/mg IgG and prekallikrein activator levels were less...

A cidade vista pelos habitantes do campo de Araponga/MG: uma análise das representações sociais por meio do software Alceste
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Gomes,Nayhara Freitas Martins; Fiúza,Ana Louise Carvalho; Pinto,Neide Maria Almeida.
Resumo: A relação entre campo e cidade vem se modificando de forma acentuada, especialmente, a partir das últimas duas décadas do século XX. O presente artigo fez uma análise da forma como a população rural de um pequeno município de economia cafeeira, localizado na Zona da Mata mineira, manifesta, por meio das suas representações de “campo” e “cidade”, a percepção de aproximações e diferenças quanto ao modo de vida rural e urbano na atualidade. O estudo teve um caráter cross-sectional, tendo sido realizado por intermédio de um questionário semiestruturado, com uma amostra representativa da população composta de 94 rurais. Na aplicação do questionário, utilizou-se da técnica de mesclagem de perguntas, que estimulavam respostas rápidas e espontâneas, com...

A cladistic re-assessment of the &lt;i&gt;Polycystis&lt;/i&gt; species complex (Polycystididae, Eukalyptorhynchia)
Provedor de dados: Open Marine Archive
Autores: Artois, T.J.; Schockaert, E.R.
The taxonomy of the genus &lt;i&gt;Polycystis&lt;/i&gt; Koelliker, 1845 &lt;i&gt;sensu&lt;/i&gt; Schockaert &amp; Karling, 1975 is discussed. Character analysis reveals the monophyletic state of the three species groups these authors defined within it. As no synapomorphies for the three groups can be found, the genus is split in three genera: &lt;i&gt;Polycystis&lt;/i&gt; Koelliker, 1845, &lt;i&gt;Macrorhynchus&lt;/i&gt; Graff, 1882 and &lt;i&gt;Paulodora Marcus&lt;/i&gt;, 1948. The systematic position of &lt;i&gt;Macrorhynchus yaganus&lt;/i&gt; (Marcus, 1954) Evdonin, 1977 is also discussed, resulting in the erection of the new genus &lt;i&gt;Marcusia&lt;/i&gt; gen. n.

A Clarification of the Status of Four Taxa in the Ectoedemia Angulifasciella Group (Nepticulidae: Lepidoptera)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wilkinson, C.; Bryan, G.; Menken, S.B.J.; Nieukerken, E.J. van.
The status of the four taxa Ectoedemia angulifasciella, E. atricollis, E. rubivora and E. arcuatella, has always been in debate. They have now been studied using several different systematic methods, relating to morphology, gel electrophoresis, host plant differentiation, life histories and distribution. Evidence is given here which demonstrates that they should be regarded as two pairs of sibling species.

A Classic Case of Annular Pancreas and its Clinical Implications
Provedor de dados: International Journal of Morphology
Autores: Nayak B,Satheesha; Mun Yooi,Ooi.
Annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. This may cause the duodenal constriction, obstruction, peptic ulcers and other complications. We saw a classic case of annular pancreas. The head of pancreas surrounded the second part of duodenum completely. However there was no narrowing of the duodenum. The case may be of importance for gastroenterologists, surgeons and radiologists.

Autores: Blumenthal, Dana M; University of Minnesota; dblumenthal@npa.ars.usda.gov; Jannink, Jean-Luc; University of Minnesota; jjannink@iastate.edu.
Collaboration among multiple stakeholders can be crucial to the success of natural resource management. In recent years, a wide variety of methods have been developed to facilitate such collaboration. Because these methods are relatively new and come from different disciplines, little attention has been paid to drawing comparisons among them. Thus, it is very difficult for potential users to sort through the increasingly large literature regarding such methods. We suggest the use of a consistent framework for comparing collaborative management methods, and develop such a framework based on five criteria: participation, institutional analysis, simplification of the natural resource, spatial scale, and stages in the process of natural resource management. We...

A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and ‘Candidatus Mycoplasma haemovis’ were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6 of 12 (50.0%) sheep imported from Australia with the infected ewe at the same time, 1 of 5 (20.0%) sheep introduced from a domestic farm in Hokkaido, and in 1 of 16 (6.3%) sheep from an epidemiologically unrelated ranch. It is the first clinical case of sheep to confirm coinfection of these pathogens in Japan.

Autores: Mejia,J.; Galvis-Alonso,O.Y.; Castro,A.A.de; Braga,J.; Leite,J.P.; Simões,M.V.
The main objective of the present study was to upgrade a clinical gamma camera to obtain high resolution tomographic images of small animal organs. The system is based on a clinical gamma camera to which we have adapted a special-purpose pinhole collimator and a device for positioning and rotating the target based on a computer-controlled step motor. We developed a software tool to reconstruct the target’s three-dimensional distribution of emission from a set of planar projections, based on the maximum likelihood algorithm. We present details on the hardware and software implementation. We imaged phantoms and heart and kidneys of rats. When using pinhole collimators, the spatial resolution and sensitivity of the imaging system depend on parameters such as...

Abstract  Background  Envenomation caused by multiple stings from Africanized honeybees Apis mellifera constitutes a public health problem in the Americas. In 2015, the Brazilian Ministry of Health reported 13,597 accidents (incidence of seven cases per 100,000 inhabitants) with 39 deaths (lethality of 0.25%). The toxins present in the venom, which include melittin and phospholipase A2, cause lesions in diverse organs and systems that may be fatal. As there has been no specific treatment to date, management has been symptomatic and supportive only.  Methods  In order to evaluate the safety and neutralizing capacity of a new apilic antivenom, as well as to confirm its lowest effective dose, a clinical protocol was developed to be applied in a multicenter,...

Autores: CASTANHO,ANDREA D.A.; COE,MICHAEL; ANDRADE,EUNICE M.; WALKER,WAYNE; BACCINI,ALESSANDRO; CAMPOS,DIEGO A.; FARINA,MARY.
Abstract  This work is focused on characterizing and understanding the aboveground biomass of Caatinga in a semiarid region in northeastern Brazil. The quantification of Caatinga biomass is limited by the small number of field plots, which are inadequate for addressing the biome’s extreme heterogeneity. Satellite-derived biomass products can address spatial and temporal changes but they have not been validated for seasonally dry tropical forests. Here we combine a compilation of published field phytosociological observations with a new 30m spatial resolution satellite biomass product. Both data were significantly correlated, satellite estimates consistently captured the wide variability of the biomass across the different physiognomies (2-272 Mg/ha). Based...

Autores: Mews,Carina M.; Cabette,Helena S.R.; Albino,Jeyson L.D.
The aim of our study was to characterize Cerataphis brasiliensis Hempel, an aphid of native palm tree of tropical savannas (cerrado), and to record intraspecific variation. We found two parthenogenetic forms of apterous viviparae females of C. brasiliensis. We differentiate the two forms through measurable and qualitative characters: (i) length of cephalic horns, (ii) number of antennal segments, (iii) presence or absence of wax glands, (iv) location of siphunculi.

A Coasian Approach to Efficient Water Allocation of a Transboundary River
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Willis,   David B.; Baker,   Justin Scott.
The United States and Mexico recently resolved a decade-old water dispute that required Mexico to repay the accumulated water debt within one year. A Coasian analysis estimates the social welfare gains attainable to each country under an alternative debt repayment scheme that allows repayment over a longer time horizon and in a combination of dollars and water, instead of solely in water. Assuming average water supply conditions, under the agreed 1-year repayment contract, U.S. compensation value is 534% greater and Mexico’s compensation cost is 60% less relative to when compensation is paid exclusively in water.

A coastal coccolithophore maintains pH homeostasis and switches carbon sources in response to ocean acidification
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Liu, Yi-wei; Eagle, Robert A.; Aciego, Sarah M.; Gilmore, Rosaleen E.; Ries, Justin B.
Ocean acidification will potentially inhibit calcification by marine organisms; however, the response of the most prolific ocean calcifiers, coccolithophores, to this perturbation remains under characterized. Here we report novel chemical constraints on the response of the widespread coccolithophore species Ochrosphaera neapolitana (O. neapolitana) to changing-CO2 conditions. We cultured this algae under three pCO(2)-controlled seawater pH conditions (8.05, 8.22, and 8.33). Boron isotopes within the algae's extracellular calcite plates show that this species maintains a constant pH at the calcification site, regardless of CO2-induced changes in pH of the surrounding seawater. Carbon and oxygen isotopes in the algae's calcite plates and carbon isotopes in...

Autores: Brandenburg, Alfio.
Este texto tem por objetivo problematizar a noção de mundo rural e analisar as condições de emergência de novos atores. A partir da ideia de colonização do rural, os personagens que reagem ao processo de racionalização unilateral da vida social e biológica são definidos como novos atores, na medida em que reconstroem relações com o ambiente social e natural. A ação de novos atores inscreve-se no contexto de um campo de disputa de linguagens ecossociais e de distintas ruralidades, construindo-se uma racionalidade que se contrapõe ao domínio da racionalidade instrumental: a racionalidade ambiental ou ecológica.

ABSTRACT This article explores decision analysis regarding Drop and Hook (D&amp;H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&amp;H systems. A D&amp;H strategy maximises truck utilisation, as semi-trailers can be handled independently of the traction unit of the trucks, which makes the transport system more agile. For internal D&amp;H systems the semi-trailer detaching/attaching point is located inside the mill site while for external D&amp;H systems it is located outside, before the trucks’ weighbridge. Each configuration requires...

A combination of STI571 and BCR-ABL1 siRNA with overexpressed p15INK4B induced enhanced proliferation inhibition and apoptosis in chronic myeloid leukemia
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Xia,D.Y.; Liu,L.; Hao,M.W.; Liu,Q.; Chen,R.A.; Liang,Y.M.
p15INK4B, a cyclin-dependent kinase inhibitor, has been recognized as a tumor suppressor. Loss of or methylation of the p15INK4B gene in chronic myeloid leukemia (CML) cells enhances myeloid progenitor formation from common myeloid progenitors. Therefore, we examined the effects of overexpressed p15INK4B on proliferation and apoptosis of CML cells. Overexpression of p15INK4B inhibited the growth of K562 cells by downregulation of cyclin-dependent kinase 4 (CDK4) and cyclin D1 expression. Overexpression of p15INK4B also induced apoptosis of K562 cells by upregulating Bax expression and downregulating Bcl-2 expression. Overexpression of p15INK4B together with STI571 (imatinib) or BCR-ABL1 small interfering RNA (siRNA) also enhanced growth inhibition and...

Autores: Rouan, Mathias; Kerbiriou, Christian; Levrel, Harold; Etienne, M.
An interdisciplinary team has applied the multi-agent system formalism to study shrub encroachment in the Biosphere Reserve on the isle of Ouessant. The main goals were (1) to understand vegetation dynamics, and (2) to represent how main agents, or actors view the dynamics of natural resources in relation to their own living practices. The management strategies established for each type of stakeholders were formalised and the impact of these strategies on biodiversity was analyzed at various temporal and spatial scales. Following a short description of the model, three aspects of the modelling process are discussed in more detail: the use of the chough (Pyrrhocorax pyrrhocorax) population as a representative variable for the interactions between...

A comparative analysis of Alexandrium catenella/tamarense blooms in Annaba Bay (Algeria) and Thau lagoon (France); phosphorus limitation as a trigger
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hadjadji, Imene; Frehi, Hocine; Ayada, Lembarek; Abadie, Eric; Collos, Yves.
Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely...

A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil
Provedor de dados: Biota Neotropica
Autores: Gonçalves,Fábio Bertolini; Menezes,Márcia Santos de.
Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average...

A Comparative Analysis of Organic and Conventional Farming trough the Italian FADN
Provedor de dados: Organic Eprints
Autores: Cisilino, Federica; Madau, Fabio A.
This paper presents some results from a wider research on economic and environmental sustainability of organic farming. It aims to compare organic and conventional farming in order to identify some of the main differences between those groups of farms that participated in the official Farm Accountancy Data Network (FADN)-2003. The study is organized in two sections. The first part, after a brief literature review of the most recent statistical methodologies applied to identify the two similar groups of farms, presents some key economic variables (production, costs and revenues) and the most widely-used structural, economic and balance sheet indexes.  The second part describes findings from a case study on the Italian fruit-growing sector.  A non-parametric...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Visawadia,   H.R.; Fadadu,   A.M.; Tarpara,   V.D.
The study has revealed that the total cost per hectare is higher in Bt cotton than hybrid cotton. The cost of seeds has been found higher in Bt cotton, whereas hybrid cotton growers incur more cost on insecticides/ pesticides. This shows the effectiveness of the new technology (Bt cotton) for insect resistance. The average total cost of production as well as the bulk line cost have been found lower in Bt cotton. This depicts a reduction in the unit cost of Bt cotton, which is the distinct advantage of the new technology. A higher yield of 29 per cent has been obtained by the Bt cotton farmers over the hybrid cotton growers. The study has identified the constraints in production, and marketing of Bt cotton in the area. Bt cotton has been found a superior...

A comparative assessment of the uncertainties of global surface ocean CO2 estimates using a machine-learning ensemble (CSIR-ML6 version 2019a) - have we hit the wall?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gregor, Luke; Lebehot, Alice D.; Kok, Schalk; Monteiro, Pedro M. Scheel.
Over the last decade, advanced statistical inference and machine learning have been used to fill the gaps in sparse surface ocean CO2 measurements (Rodenbeck et al., 2015). The estimates from these methods have been used to constrain seasonal, interannual and decadal variability in sea-air CO2 fluxes and the drivers of these changes (Landschutzer et al., 2015, 2016; Gregor et al., 2018). However, it is also becoming clear that these methods are converging towards a common bias and root mean square error (RMSE) boundary: "the wall", which suggests that pCO(2) estimates are now limited by both data gaps and scale-sensitive observations. Here, we analyse this problem by introducing a new gap-filling method, an ensemble average of six machine-learning models...

A comparative expression analysis of gene transcripts in brain tissue of non-transgenic and GH-transgenic zebrafish (Danio rerio) using a DDRT-PCR approach
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Alves-Costa,Fernanda A.; Figueiredo,Márcio A.; Lanes,Carlos F.C.; Almeida,Daniela V.; Marins,Luis F.; Wasko,Adriane P.
The presence of higher level of exogenous growth hormone (GH) in transgenic animals could lead to several physiological alterations. A GH transgenic zebrafish (Danio rerio) line was compared to nontransgenic (NT) samples of the species through a DDRT-PCR approach, with the goal of identifying candidate differentially expressed transcripts in brain tissues that could be involved in GH overexpression. Densitometric analyses of two selected amplification products, p300 and ADCY2, pointed to a significant lower gene expression in the transgenic zebrafish (104.02 ± 57.71; 224.10 ± 91.73) when compared to NT samples (249.75 ± 30.08; 342.95 ± 65.19). The present data indicate that p300 and ADCY2 are involved in a regulation system for GH when high circulating...

A comparative profitability analysis of organic and conventional farms in Emilia-Romagna and in Minnesota
Provedor de dados: Organic Eprints
Autores: Canavari, Maurizio; Ghelfi, Rino; Olson, Kent D.; Rivaroli, Sergio.
Recent discussion surrounding organic agriculture (also referred to as organic farming) has turned from just whether it represents a viable alternative to conventional agriculture to whether it would be adopted by a significant percentage of farmers. After a beginning phase in which the adoption was mainly due to an ethically based choice of the farmer, the success in the market and the increasing demand for organic products are increasing the number of farmers converting their farming system. Despite the continuing importance of non-economic factors and the uncertainty given by short-term and mid-term fluctuations of prices, a decisive point is whether the conversion to organic farming may be worthwhile from an economic perspective. The aim of the paper...

Intact natural gas hydrates recovered on the West Aftican margin in the South Atlantic Ocean (ZaiAngo and Neris IIrojects) and from the Norwegian Sea (Hakon Mosby Mud Volcano) are investigated by micro-Raman spectroscopy at ambient pressure and low temperature. The gas hydrates collected at different geological sites contain a high methane concentration relative to other minor components that are slightly dispersed in the samples. They crystallize in a type I cubic lattice structure as also confirmed by our preliminary synchrotron diffraction results obtained on the ZaiAngo specimen. However, detailed analysis of selected microscopic areas reveals a variation in the gas distribution among the different specimens. Trace amounts of CO2 and H2S can be...

Provedor de dados: International Journal of Morphology
Autores: Ilknur,Ari; Mustafa,Kafa Ilker; Sinan,Bakirci.
The pterion is a commonly used anthropologic and neurosurgical landmark defined as the junction of the sphenoid, temporal, parietal and frontal bones. It is commonly classified into four types based on sutural pattern: sphenoparietal, in which the sphenoid and parietal bones are in direct contact; frontotemporal, in which the frontal and temporal bones are in direct contact; stellate, in which all four bones come into contact at a point; and epipteric, in which a small sutural bone is found between the parietal bone and the greater wing of the sphenoid bone. In the present study, 44 Anatolian skulls from two different eras, Byzantine (13th century) and contemporary (20th century), were investigated for morphology and location of the pterion.

Gut content analysis of Oreochromis niloticus from the Nyanza Gulf,     Lake Victoria showed that the bulk of the food items ingested     constituted bottom deposits and blue green algae. Among the live food     items ingested, blue green algae (Cyanophyceae) constituted 53.6%, the     diatoms (Bacillariophyaceae) 19.7%, aquatic invertebrates (mainly     Copepoda, Cladocera, and Rotifera) 12.9%, desmids (Desmidaceae) 7.7%     and lastly the green algae (Chlorophyceae) 6.2%. The most preferred     food items were: Spirulina laxisma and Nitzschia accicularis. The     least preferred food items were: Lyngbya circumcreta, Microcystis     aeruginosa and Pediastrum simplex. The quantity of food eaten by O.     niloticus to satiation ranged from 0.016-4.5% body...

African catfish (&lt;i&gt;Clarias gariepinus&lt;/i&gt;) larvae were fed on five preparations of decapsulated Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; cysts: 1) dried (35°C, 6 h) and UV-irradiated cysts; 2) heated cysts (80°C, 10 min); 3) brine dehydrated and UV irradiated cysts; 4) micro-bound diet 1(with intact decapsulated cysts used in diet preparation 1); and 5) micro-bound diet 2 (with crushed and shifted decapsulated diet used in diet preparation 1). The larvae were fed from the first day after yolk-sac resorption (fourth day after hatching). After a 14-d rearing period, larvae fed on dried or heated decapsulated cysts or micro-bound diet 1. Feeding micro-bound diet 2 resulted in a significantly lower average gain in weight as compared to the other...

A COMPARATIVE THEORETICAL ANALYSIS OF THE IMPACT OF THE FOOD STAMP PROGRAM AS OPPOSED TO CASH TRANSFERS ON THE DEMAND FOR FOOD
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Phillips,   Kathryn S.; Price,   David W.
Comparative analysis of food demand expansion of a cash program, as compared to the food stamp program, is important for measuring trade-offs between goals of raising farm income and increasing food expenditures of the poor.  A theoretical basis for assessing food demand impacts under each program is presented.  Two effects are analyzed: 1) The effect on food demand of the individual household and 2) The effect of food demand at the aggregate level.  Both indifference curve analysis and psychological need level theory are used.

An indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) for ochratoxin A (OTA) detection in green, roasted and instant coffees was developed using anti-OTA monoclonal antibody. Immunological reagents prepared were OTA-BSA (4.76 mg/mL), anti-OTA.7 MAb (2x10³-fold dilution) and HRP-anti IgG (10³-fold dilution). The detection limit was 3.73 ng OTA/g and correlation coefficients (r) between this immunoassay and high performance liquid chromatography were 0.98 for green coffee, 0.98 for roasted and 0.86 for instant. OTA levels detected by ic-ELISA were higher than by HPLC, with ELISA/HPLC ratio of 0.66 - 1.46 (green coffee), 0.96 - 1.11 (roasted) and 0.93 - 1.82 (instant). ELISA recoveries for OTA added to coffee (5 - 70 ng/g) were 81.53 % for...

A comparison between models describing the influence of temperature on the development rate of copepods
Provedor de dados: Open Marine Archive
Autores: Heip, C.H.R.
Four mathematical expressions relating development time to temperature are compared. All four yield good predictions of the development rate of the copepod &lt;i&gt;Tachidius discipes&lt;/i&gt;. The use of the equation of Belehradek is criticized. It is concluded that the power equation D= aT&lt;sup&gt;b&lt;/sup&gt; gives the best approximation in this case.

A Comparison between Perception of Risk and Willingness to Serve Genetically Modified Foods
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nganje,   William E.; Wachenheim,   Cheryl J.; Lesch,   William C.
The dichotomy between perceptions of the acceptability of risk associated with genetically modified (GM) foods and willingness to consume GM foods is investigated. Results indicate that some consumers are willing to consume GM foods even though they may perceive such foods as somewhat unsafe, with determinants such as self-perceived knowledge about the availability of GM foods and altruistic motives having positive and significant effects on their consumption decisions. Efforts toward decreasing perception of risk and ultimately increasing acceptance of and demand for GM foods should address issues related to their altruistic characteristics and outrage.

Abstract Next-generation sequencing (NGS) platforms allow the analysis of hundreds of millions of molecules in a single sequencing run, revolutionizing many research areas. NGS-based microRNA studies enable expression quantification in unprecedented scale without the limitations of closed-platforms. Yet, whereas a massive amount of data produced by these platforms is available, comparisons of quantification/discovery capabilities between platforms are still lacking. Here we compare two NGS-platforms: SOLiD and PGM, by evaluating their microRNA identification/quantification capabilities using two breast-derived cell-lines. A high expression correlation (R2 &gt; 0.9) was achieved, encompassing 97% of the miRNAs, and the few discrepancies in miRNA counts were...

The immobilization of Saccharomyces cerevisiae DSM 70424, Saccharomyces ludwigii DSM 3447 and Saccharomyces rouxii DSM 2531 on brewer's spent grain and then ethanol production and sugar consumption of these immobilized yeasts were investigated. The aim of this study was to investigate the abilities of these three immobilized yeasts for producing alcohol for brewing at two temperatures (7 and 12 °C) using two different sugar levels (one at original level supplied in the brewery and one with 2.5% (w/v), added glucose to the wort). Increasing both parameters resulted in higher alcohol production by all the yeasts studied. At 7 °C and with original wort density the ethanol content at the end of fermentation was 2.7% (v/v) for S. cerevisiae, 1.7% for S....

A comparison of abundance estimators for small mammal populations
Provedor de dados: Revista Brasileira de Zoologia
Autores: Pacheco,Marcelle; Kajin,Maja; Gentile,Rosana; Zangrandi,Priscilla L.; Vieira,Marcus V.; Cerqueira,Rui.
A major difficulty in the application of probabilistic models to estimations of mammal abundance is obtaining a data set that meets all of the assumptions of the model. In this paper, we evaluated the concordance correlation among three population size estimators, the minimum number alive (MNA), jackknife and the model suggested by the selection algorithm in CAPTURE (the best-fit model), using long-term data on three Brazilian small mammal species obtained from three different studies. The concordance correlation coefficients between the abundance estimates indicated that the probabilistic and enumeration estimators were highly correlated, giving concordant population estimates, except for one species in one of the studies. The results indicate the...

A Comparison of Actual and Hypothetical Willingness to Pay of Parents and Non-Parents for Protecting Infant Health: The Case of Nitrates in Drinking Water
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Loomis,   John B.; Bell, Paul; Cooney, Helen; Asmus, Cheryl.
We estimate adults’ willingness to pay (WTP) to reduce health risks to their own or other families’ infants to test for altruism. A conjoint analysis of adults paying for bottled water found marginal WTP for reduction in risk of shock, brain damage, and mortality in the cash treatment of $2, $3.70, and $9.43, respectively. In the hypothetical market these amounts were $14, $26, and $66, indicating substantial hypothetical bias, although not unexpected due to the topic of infant health. Statistical tests confirm a high degree of altruism in our WTP results, and altruism held even when real money was involved.

Autores: Loomis,   John B.; Asmus, Cheryl; Bell, Paul.
The objective of this research was to estimate adults' willingness to pay to reduce health risks to their or other families's infants, the latter to test for altruism. A choice experiment was conducted by having adults pay for bottled water for infants to reduce infants' exposure to nitrates in drinking water. Since nitrates only affect infants' health, we have isolated the adults' willingness to pay just for infants' health by buying bottled water to avoid infants' nitrate intake. Respondents were separated into two treatments, one with hypothetical choices, and the other where respondents were told that one of their four choices would be binding, and they would actually buy bottled water using money given to them at the beginning of the experiment....

A Comparison of Approaches to Mitigate Hypothetical Bias
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Champ,   Patricia A.; Moore,   Rebecca; Bishop,   Richard C.
We compare two approaches to mitigating hypothetical bias. The study design includes three treatments: an actual payment treatment, a contingent valuation (CV) treatment with a follow-up certainty question, and a CV treatment with a cheap talk script. Our results suggest that both the follow-up certainty treatment and the cheap talk treatment produce willingness-to-pay (WTP) estimates consistent with the actual payment treatment. However, the follow-up certainty treatment provides response distributions at all offer amounts that are statistically similar to the actual payment treatment, while the cheap talk treatment provides similar responses only at some offer amounts. Furthermore, the cheap talk treatment is effective only for inexperienced individuals....

A Comparison of Auction and Choice Experiment: An Application to Consumer Willingness to Pay for Rice with Improved Storage Management
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Su,   Lianfan; Adam,   Brian D.; Lusk,   Jayson L.; Arthur,   Frank.
Experimental auction and discrete choice experiment are two popular value elicitation methods. Theoretically they should yield the same results but empirical results have been mixed (e.g., Lusk and Schroeder 2004, 2006; Corrigan et al. 2010.) This study uses both methods to determine consumers’ willingness to pay (WTP) for rice with improved insect control and for rice stored using Integrated Pest Management (IPM). This study investigates two potential reasons – anchoring and information – for why some studies have found apparent inconsistencies between auction and choice experiment results. Results indicate that consumers’ WTP derived in the auction and choice experiments are significantly different. Consumers’ average bids in the auction are higher than...

Autores: Weinberg, Steven.
Seven coral reef survey methods were compared in an experimental plot of 100 m² on a Caribbean shelf reef off southwest Puerto Rico. This area was mapped in detail by means of underwater photography and in situ drawings, in order to provide an objective standard against which to test the results obtained by the different survey methods. Minimal survey area was determined, and minimal sampling time deduced for one of the most laborious methods. Two 45-minute periods (i.e. 1.6 X minimal time) were chosen arbitrarily as the standard time alotted to each method. Three survey criteria were chosen: number of species observed, relative coverage (in %) and population densities (in colonies m²). The results of the latter two methods were compared to real values (as...

A COMPARISON OF CRITERIA FOR EVALUATING RISK MANAGEMENT STRATEGIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baker,   Timothy G.; Gloy,   Brent A.
Several criteria that produce rankings of risk management alternatives are evaluated.  The criteria considered are Value at Risk, the Sharpe ratio, the necessary condition for first degree stochastic dominance with a risk free asset, and the necessary condition for second degree stochastic dominance with a risk free asset.  The effectiveness of the criteria increases as decision-makers are assumed to be more risk averse and have greater access to financial leverage.

A comparison of energy use in organic and conventional agriculture in Spain
Provedor de dados: Organic Eprints
Autores: Alonso, Antonio M.; González, Rodrigo; Foraster, Laia; Guzmán, Gloria I.; García, Roberto.
The current situation of worldwide concern over the emission of greenhouse gases and its effect on the climate demands an evaluation, from the perspective of energy efficiency and more specifically of non-renewable energy sources, of tendencies for change in the management of agricultural systems that have arisen in recent years. This article uses energy balances to evaluate the contribution of organic agriculture to the increase in the energy efficiency of Spanish agriculture. The results show the higher nonrenewable energy efficiency (NREE) and the lower use of nonrenewable energy (NRE) in organic systems compared with conventional ones. Nevertheless, agricultural systems in general could still improve their energy efficiency.

Autores: Luyten, S.; Smeyers-Verbeke, J.; Massart, D.L.
In clinical chemistry it can be very useful to have a rapid method for the determination of trace elements in biological material available. Because the classical wet digestion method which is generally used for the destruction of biological materials requires much attention, two procedures were tried which should be less time consuming or require less attention. The two new procedures which are the soluene (a quaternary ammonium hydroxide) method of Jackson (1) and the method of Adrian (2) utilizing pressure were applied to the determination of Cu and Zn in human brain tissue and in fish meal by atomic absorption spectroscopy.

The financial implications of manipulating nitrogen (N) inputs and management strategies for beef production systems were assessed. One-hectare grassland farmlets were grazed to a target sward height by beef steers; herbage surplus to grazing requirements was cut for silage. Three systems were compared: ‘CN’, conventional mineral N application to a grass monoculture and broadcast slurry; ‘TN’, tactical mineral N application at fortnightly intervals to a grass monoculture with slurry injection and the early housing of cattle; ‘GC’, a mixed grass/white clover sward with no mineral N addition and slurry injection. Comparisons were made on two contrasting soil types: a freely-draining sandy loam (site 1) and a poorly drained clay (site 2). Financial budgets...

Food security—consistent access to enough food for an active, healthy life—is essential for health and good nutrition. The extent to which a nation’s population achieves food security is an indication of its material and social well-being. Differences in the prevalence of household level food insecurity between Canada and the United States are described at the national level and for selected economic and demographic subpopulations. Associations of food security with economic and demographic characteristics are examined in multivariate analyses that hold other characteristics constant. Comparable measures of household food security were calculated from the nationally representative Canadian Community Health Survey Cycle 2.2 (2004) and the U.S. Current...

Thrce ditferent methodologies frequently employed to evaluate the indexes that report the antioxidant capabilities of pure compounds and/or complex mixtures of antioxidants are applied to a series of mono- and polyphenols, as well as to two wine (red and white) samples. These methodologies are based on the bleaching of a stable radical, the effect of the additive upon luminol chemiluminescence induced by peroxyl radicals, and the effect of the additive upon the bleaching of the fluorescence from a dye molecule. Widely ditferent responses are obtained from the different methodologies. These differences are interpreted in terms of the different factors (stoichiametric factors and/or reactivities) that determines the indexes evaluated by these different...

A COMPARISON OF MINNESOTA'S FARM BUSINESS MANAGEMENT ASSOCIATION MEMBERS AND THE USDA'S FARM COSTS AND RETURNS SURVEY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Andersson,   Hans; Olson,   Kent D.
Many states have farm record associations which collect individual farm data. This data are used for research, extension, and teaching purposes. However, since membership in the associations is voluntary, the question arises whether the members are representative of the population of all farmers in that area. This study compares farm record data collected through the Southeastern and Southwestern Minnesota Farm Business Management Associations (FBMA) and data obtained through the USDA's Farm Costs and Returns Survey (FCRS). Both data sets were for 1987. By design, the FCRS survey is not subject to the self-selection bias that may occur in the FBMA data. The objectives of this study are to: (1) determine which farm characteristics are statistically the same...

Provedor de dados: Organic Eprints
Autores: Kochakinezhad, Hamed; Peyvast, Gholam-Ali; Kashi, Abdol-Karim; Olfati, Jamal-Ali; Asadi, A.
Tomato (Lycopersicon esculentum Mill.) is one of the most popular and versatile vegetables in the world, and organic production with a high yield and desirable quality is a target of many producers. The effect of four different fertilizers (chemical, municipal solid waste compost, cattle manure, and spent mushroom compost) on four commercial tomato cultivars (Redstone, Flat, Peto Pride and Chief) was assessed in this research. The highest yield was obtained with the Chief cultivar when fertilized with chemical fertilizer and the lowest value was obtained with Peto Pride fertilized with 20 tonnes per hectare (t/ha) of cow manure. The difference between the two classes of fertilizers (organic and chemical) was not very high so that organic fertilizers are...

Autores: Tabaglio, Prof. Vincenzo; Gavazzi, Dott. Carolina; Nervo, Dott. Giuseppe.
A four-year field trial (2004-2007) was carried out to compare performances of organic and conventional farming systems in the Po Valley (Northern Italy). Four vegetable crops were grown in the sequence: 2004 – processing tomato; 2005 – bean followed by savoy cabbage; 2006 – processing tomato; and 2007 – zucchini. The experimental design was a split-plot with four replicates, the management system being the main factor (OF, organic farming vs. CF, conventional farming) with the rate of nitrogen fertilisation as the secondary factor. N efficiency of the organic fertilizers was assumed as being 50-75%). In all four of the years studied, the two farming systems did not show significant differences in marketable yields for any vegetable crops. The reduction in...

A comparison of paraffin and resin-based techniques used in bark anatomy
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hamann, T.; Smets, E.; Lens, F.
Bark anatomy is an unappreciated discipline in plant systematics, despite its great potential to reveal systematically informative features. In this paper, main reasons for the lack of detailed bark anatomical data in many plant families are identified, including problems with sectioning, terminological issues, and difficulties in observation of dilated stems. We deal with these problems by focusing on two aspects: (1) compare, discuss and improve existing sectioning and maceration techniques using two species with soft and hard bark tissues; and (2) discuss the best way to collect stem bark samples. We hope that this paper will stimulate inclusion of bark anatomical data in future systematic studies.

Provedor de dados: Organic Eprints
Autores: Koller, Martin; Alföldi, Thomas; Siegrist, S.; Weibel, Franco.
In Switzerland, transplants for organic vegetable growing have been fertilised traditionally with slaughterhouse by-products. In autumn 2000, the Swiss government restricted the use of such products because of the BSE crisis. To maintain the production of organic transplants, alternative fertilisers needed to be tested. Eleven alternatives to horn powder (standard fertiliser) were selected based on the organic standards of the European Union, including feather powder (as an animal based product without BSE risk). The products were mixed with a standard growing media for organic transplants in a concentration of 300 mg nitrogen L-1 growing media. Different experiments where set up with head lettuce (Lactuca sativa), Chinese cabbage (Brassica rapa var....

Small farmers have played an important role in maintaining genetic resources of traditional varieties. Collecting and characterizing germplasm, especially landraces and heirloom varieties, are strategic activities that would create a knowledge base describing the traditional varieties of a given region and reduce the risk of genetic erosion. The objectives of this work were as follows: collect sweet potato roots from rural properties and local markets in Rio de Janeiro State, Brazil; characterize the accessions using RAPD and ISSR molecular markers, comparing the efficiency in discrimination of these two types of molecular markers; and estimate the genetic variability of the population. Fifty-nine samples from rural properties and 19 from local markets...

A Comparison of Risk and Return Characteristics of Efficient Crop Portfolios for the Brown Soil Zones Saskatchewan and Mecklenburg, Germany
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schoney,   Richard A.; Moeller,   Christof.
Two efficient farms are constructed for the brown soils of Saskatchewan, Canada and for Mecklenburg, Germany based on producer panels. Both farms feature highly integrated cropping systems which take advantage of cropping synergies. However, farm risk is inherently different between the two because differences in 1) climate that gives rise to very different yield risk and cost structure, and 2) EU programs which offer fixed cash payments and stable sugar beet prices. As expected, risk is much higher for the Saskatchewan case farm - it has a chance of a negative cash flow of approximately one year in five. In sharp contrast, the Mecklenburg has very little chance of generating a negative cash flow. Hence, it is easy to understand why crop insurance and...

Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average...

Provedor de dados: Organic Eprints
Autores: Hathaway-Jenkins, L. J.; Sakrabani, R; Pearce, Bruce; Whitmore, A. P; Godwin, R. J.
Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields. The physical soil properties varied...

A comparison of soil properties under organic and conventional farming in Australia
Provedor de dados: Organic Eprints
Autores: Nachimuthu, Gunasekhar; Kristiansen, Paul; Lockwood, Peter; Guppy, Chris.
Organic farming is an alternative to conventional farming for providing sustainable crops with high export demand. This review analyses research findings on organic farming in Australia, with an emphasis on soil health. Several reports have indicated that organic farm management generally improves soil physical properties in Australia and elsewhere. Although low nitrogen (N) availability can constrain yields, organic farmers can improve N supply through legume green manures. Plant available phosphorus (P) is a more serious limiting factor in organic farming, particularly in Australia with naturally low P levels. Phosphorus is less easily replaced in the soil than N, and there is a need for alternate sources of organic-certified P and methods to enhance P...

Autores: Sangakkara, U.R.; Amerasekera, P.; Bandaranayake, P.R.S.D.
Weeds are a major problem in organic or Nature Farming systems and mechanical methods are generally used for weed control. However either mulching or growing crop in-between rows of the principal crop offers scope as a means of protecting soil and suppressing weeds. Field studies thus evaluated the impact of either a mulch or growing two intercrops as possible management strategies for controlling weeds of vegetables grown in major and minor seasons of the tropics under a Nature Farming regime. All three strategies controlled weed numbers, their biomass and increased crop yields. However the least beneficial impact was from the dead leaf mulch, while the highest degree of weed control and increments in crop yields was with the green manure intercrop. The...

Analyses of surface eddy kinetic energy (EYE) inferred from 5 years of merged TOPEX/Poseidon and ERS-1/2 altimetric data are presented in the Gulf Stream (GS) and the Kuroshio (KS) Current systems, focusing on anisotropy and EKE seasonal, interannual, and long-term variations, as well as Reynolds stresses. For both GS and KS a descriptive analysis of the EKE field shows that it is anisotropic along the path of the currents and assesses the close relationship between the spatial distribution of EKE high levels and bottom topography. A striking ocean feature is found in the GS, shaped as a zonal "double-blade" structure in the EKE field, centered at 37 degrees N, 71.5 degrees W, that likely corresponds to a regular and permanent lateral displacement of the...

A comparison of the application of a biological and phenetic species concept in the Hebeloma crustuliniforme complex within a phylogenetic framework
Provedor de dados: Naturalis Digital Academic Repository
Autores: Aanen, Duur K.; Kuyper, Thomas W.
A method is presented to derive an operational phenetic species concept for the Hebeloma crustuliniforme complex in northwestern Europe. The complex was found to consist of at least 22 biological species (intercompatibility groups; ICGs). Almost none of these biological species could be recognised unambiguously by morphological criteria. It is therefore necessary to base a phenetic species concept on combinations of biological species. However, such species delimitation must be performed within an explicitly phylogenetic context. It is crucial therefore to have a reliable estimate of the phylogeny of 22 biological species in that complex. Based on two nuclear sequences, we present a best estimate of the phylogeny of biological species within the complex....

Many researchers have advocated in recent times that antiseptic use in healing wounds should be discouraged. Antiseptics have been found to retard healing of wounds. Innocuous solutions like normal saline and tap water are being considered as better alternatives to antiseptics. Chlorhexidine, a commonly used antiseptic, is known to be less toxic on granulation cells. We decided to compare the effect of chlorhexidine, normal saline and tap water on healing wounds. Three groups of wistar rats had 2 by 2cm full thickness wounds made on their right dorsolateral flanks. The wounds were dressed with either chlorhexidine, normal saline or tap water. Wounds were examined at three-day intervals and measurements of area covered were taken on the first day of study...

The M3 generation was used to identify the most effective mutagen and dose for induction of mutations. The average effectiveness of EMS was much higher than γ-rays. The lowest dose of γ-rays (200 Gy) and the lowest concentration of EMS (0.5%) showed the highest mutagenic efficiency in all genotypes. Analysis of the M3 generation data based on parameters such as the variance ratio and the difference in residual variances derived from the model of Montalván and Ando indicated that...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vergara,   Oscar.
The flooding situation in 2011 is similar in nature to the Great Mississippi Flood of 1993, but different in the particulars. First, the timing of the flood within the growing season is different. Second, the two floods occurred in different regions, with the 1993 flood affecting a portion of the Corn Belt and the 2011 flood affecting a region farther south. While floodwaters have inundated several million acres of cropland in 2011, yield losses from delayed planting are expected to be limited. Furthermore, the affected states from the current flood are primarily Group 2 states under the current SRA, which are provided with greater reinsurance protection by the government than the Group 1 states.

Most anesthetics have an immuno-suppressive effect on cellular and neurohumoral immunity, and research shows that total intravenous anesthesia (TIVA) with propofol has a greater immuno-protective effect than inhalational anesthesia in human medicine. However, in veterinary clinics, these effects remain ambiguous. To clarify the details, we focused on propofol and isoflurane, investigating clinical blood hematology and immunological profiles drawn from healthy dogs under and after two anesthesia techniques. Twelve healthy adult beagles were included in this study, randomly assigned to the propofol anesthesia group (group P: n=6) or the isoflurane anesthesia group (group I: n=6).

A comparison of the structure of ovules and seeds in Stemona (Stemonaceae) and Pentastemona (Pentastemonaceae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bouman, F.; Devente, N.
Stemona and Pentastemona differ clearly in the size and structure of their ovules and seeds. Especially the development, shape, and cell wall thickenings of the endotestal cells, and by consequence the origin of the seed ridges, show marked differences. The embryological and seed anatomical characters support the proposal to give Pentastemona a family status.

Provedor de dados: Acta Agronómica
Autores: Martínez-Márquez,Ascensión; Morante-Carriel,Jaime Alfredo; Bru-Martínez,Roque.
Abstract: Cocoa, Theobroma cacao L. is one of the main tropical industrial crops. Cocoa has a very high level of interfering substances, such as polysaccharides and phenolic compounds that could prevent the isolation of suitable protein. Efficient methods of protein extraction are a priority to successfully apply proteomic analyses. We compared and evaluated two methods (A and B) of tissue preparation for total protein extract by phenol/SDS extraction protocol. The difference in the application of the two methods was that extensively washed dry powder of pod tissue were made in Method A, whereas that crude extract were prepared Method B. Extracted proteins were examined using one-dimensional electrophoresis (1-D). Results show that each extraction method...

A Comparison of Traditional and Newly Emerging Forms of Cooperative Capitalization
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barton,   David G.
This paper compares the traditional forms of capitalization used by American co-ops to newly emerging forms. It is based on an in-depth review of several case co-ops. A broad framework is provided that may be beneficial in more extensive studies of capitalization practices of cooperatives and similar organizations. It is divided into three parts.  Part One outlines the alternative capitalization forms being used by cooperatives and their antecedents, where conversions to other structures and forms have occurred. Two basic capitalization forms have been used by cooperatives: traditional (open) and new generation (closed). Cooperatives using both forms have elected to add new capitalization features, such as use of publicly listed stock, or have elected to...

Estimating the current risk of coastal flooding requires adequate information on extreme sea levels. For over a decade, the only global data available was the DINAS-COAST Extreme Sea Levels (DCESL) dataset, which applies a static approximation to estimate extreme sea levels. Recently, a dynamically derived dataset was developed: the Global Tide and Surge Reanalysis (GTSR) dataset. Here, we compare the two datasets. The differences between DCESL and GTSR are generally larger than the confidence intervals of GTSR. Compared to observed extremes, DCESL generally overestimates extremes with a mean bias of 0.6m. With a mean bias of -0.2m GTSR generally underestimates extremes, particularly in the tropics. The Dynamic Interactive Vulnerability Assessment model is...

A comparison of two techniques to discriminate continental origin of Atlantic salmon (Salmo salar L.) off West Greenland
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Reddin, David; De Pontual, Helene; Prouzet, Patrick.
Two techniques of stock discrimination both utilizing scales, i. e. termed as classical technique and shape analysis, are compared for discriminating between North American and European Atlantic salmon (Salmo salar L.) caught off West Greenland. Three scales from each of 60 salmon were analyzed: 30 from North American and 30 from European-origin salmon collected from home rivers in 1982. The best results indicated misclassification and error rates of 0% for shape analysis and 5.0% and ± 1.7%, respectively, for the classical technique. A nested ANOVA indicated that variation was greater between scales of salmon of North American and European origin than from several scales from the same salmon. It was concluded that shape analysis with computer-aided...

The usage of natural products is becoming an increasingly common consumer phenomenon due to increasing health consciousness, and because of their naturalness, and medicinal qualities of the products. African countries are very rich with natural products resources and supplies. The continent’s rich botanical heritage offers an excellent opportunity to diversify away from other traditional exports. Europe and the USA are particularly promising markets for natural products. Thus, it is advantageous to examine development of natural products exporting as alternative or complimentary economic opportunities for many African people, especially those in the rural areas. This paper has explores both factors which promote and which act as obstacles to the natural...

A COMPETITIVENESS STUDY OF FOUR RICE PRODUCTION SYSTEMS IN TRINIDAD AND TOBAGO
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Seecharan,   Denny; Jacque,   Andrew Eliel.
Rice imports into Trinidad and Tobago in 2005 represented approximately 95% of domestic demand. Local production has been declining since reaching a peak of 21,000 tonnes in 1992.  Present production is 3,500 tonnes.  Rice is produced under a variety of production systems and on farms of varying sizes, productivity and quality of output.  This paper examines the competitiveness of four production systems used in Trinidad and Tobago, viz.: the transplanting system (ST), the broadcast seeded system (SB)(both being small farms and highly labour intensive), the partially mechanized system of medium sized farms (MM) and a fully mechanized large farm utilizing aerial technology in the production system (CRP).  The methodology involved the collection of data on...

A complementary method for production of tetraploid Crassostrea gigas using crosses between diploids and tetraploids with cytochalasin B treatments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mccombie, Helen; Ledu, Christophe; Phelipot, Pascal; Lapegue, Sylvie; Boudry, Pierre; Gerard, Andre.
We present a new method to produce tetraploid Crassostrea gigas by cytochalasin B inhibition of polar body 2 expulsion in diploid females crossed with tetraploid males. This offers a means of direct introgression of genetic characters from selected diploid to tetraploid lines, avoiding a triploid step. Offspring larval ploidy shifted over time and depended on size, with tetraploids more frequent among the smaller larvae and triploids among the large. Viable tetraploids were found at 4 and 6 months, indicating the technique was successful. The possibility that gynogenesis occurred was tested by microsatellite analysis to confirm the presence of paternally inherited alleles. These were present in all animals of the 2n x 4n + CB (female first) cross. However,...

Autores: Büttikofer, J.
When, in my » Review of the genus Rhipidura”, I was to decide what to make of the two specimens from Mount Arfak, described antea, p. 82, species 43, I believed them, on the authority of Dr. A. B. Meyer, to be specifically distinct from his R. cinnamomea. Our Arfak birds, as well as the specimens mentioned by Dr. Meyer as R. brachyrhyncha, , thus belonging neither to this latter species nor to the closely allied R. cinnamomea Meyer, nor being, in my mind, the females of R. atra Salvad., they were enregistered as a new species, which I named R. meyeri in honor of Dr. Meyer, who was the first to give a description of the bird and who only with some hesitation identified it with R. brachyrhyncha Schlegel.

The equatorial eastern Indian Ocean hosts a diffuse plate boundary, where widespread deformation accommodates the relative motion between the Indian, Australian and Capricorn sub-plates. We integrate IODP Expedition 362 borehole data, which for the first time provides an accurate, ground-truthed chronostratigraphy of the sedimentary sequence east of the Ninety East Ridge (NER), with 2D seismic reflection profiles and multibeam bathymetry to assess the styles of faulting between the NER and the Sunda subduction zone, timing of activity and comparison with physical and rheological properties. We identify four distinct fault sets east of the NER in the northern Wharton Basin. N-S (350-010°) orientated faults, associated with the N-S fracture zones formed at...

A Composite Fuzzy Indicator for Assessing Farm Household Potential for Non-farm Income Diversification
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fritzsch,   Jana.
European politicians encourage the income diversification of rural households through various measures. Although being aware of farm households’ potential for non-farm income diversification seems important for finely-targeting such policy measures, no attempt has thus far been made to summarise the various determinants of income diversification in a single figure. This contribution aims to close this gap. A composite fuzzy indicator that measures farm household potential for non-farm income diversification is developed and applied to 1,053 farm households in Bulgaria, Hungary, Poland, Romania, and Slovenia. The indicator summarises the incentives of and capacities for non-farm income diversification on the individual household member level, and on the...

Velocity measurements collected by an upward-looking acoustic Doppler current profiler were used to provide the first study of ambient turbulence in Alderney Race. Turbulence metrics were estimated at mid-depth during peak flooding and ebbing tidal conditions. The dissipation rate ε and the integral lengthscale (L) were estimated using two independent methods: the spectral method and the structure function method. The spectral method provided ε and (L) estimates with standard deviations twice lower than that obtained from the structure function method. Removal of wave and Doppler noise-induced bias when estimating the dissipation rate was shown to be a crucial step in turbulence characterization. It allowed for a significant refining in (L) estimates...

Autores: Donnet, Sebastien; Lazure, Pascal; Ratsimandresy, Andry; Han, Guoqi.
While the dynamics of narrow fjords, i.e. narrow with respect to their internal Rossby radius, have been widely studied, it is only recently that interest sparked in studying the physics of broad fjords due to their importance in glacial ice melting (in Greenland, especially). Here, we present a comprehensive set of data collected in Fortune Bay, a broad, mid-latitude fjord located on the Northwest Atlantic shores. Aside from being wide (15–25 km width) and deep (600 m at its deepest), Fortune Bay also has the characteristics of having steep slopes, weak tides and of being strongly stratified from spring to fall. Thus, and since strong along-shore winds also characterise the region, this system is prone to interesting dynamics, generally taking the form of...

Abstract Pork is the most popular meat in the world. Unfortunately, the selection pressure focused on high meat content led to a reduction in pork quality. The present study used RNA-seq technology to identify metabolic process genes related to pork quality traits and fat deposition. Differentially expressed genes (DEGs) were identified between pigs of Pulawska and Polish Landrace breeds for two the most important muscles (semimembranosus and longissimus dorsi). A total of 71 significant DEGs were reported: 15 for longissimus dorsi and 56 for semimembranosus muscles. The genes overexpressed in Pulawska pigs were involved in lipid metabolism (APOD, LXRA, LIPE, AP2B1, ENSSSCG00000028753 and OAS2) and proteolysis (CST6, CTSD, ISG15 and UCHL1). In Polish...

Laparoscopic surgeries were first introduced in the 1980s. More recently, similar techniques such as natural orifice transluminal endoscopic surgery and other advanced transumbilical surgeries have been developed. With all of these surgical advances, basic information about the umbilicus is lacking. This study evaluated the relationship between umbilical diameter and thickness, as well as the underlying vessels, in order to develop a simple means of assessing umbilical anatomy. We retroactively reviewed 842 computed tomography images that included the umbilicus. Umbilical thickness, diameter, type of vessel located beneath the umbilicus, depth to the vessel, and other parameters were measured. Age and sex were noted, and their relationship was analyzed as...

Autores: Resende,Isa Lucia de Morais; Araújo,Glein Monteiro de; Oliveira,Ana Paula de Assis; Oliveira,Ana Paula de; Ávila Júnior,Rubem Samuel de.
Murundu é um tipo de microrrelevo em forma de pequena elevação, geralmente arredondado, muitas vezes apresentando solo e vegetação diferentes da área circundante. Todos os morrotes encontrados em 1,08ha de um campo de murundu foram medidos (comprimento, largura e altura). Determinou-se a profundidade do lençol freático e as características do solo sobre os mesmos e na área plana adjacente. A vegetação lenhosa (cipós, arbustos e árvores) com diâmetro do caule ao nível do solo &gt; 5mm foi amostrada em 48 morrotes. Encontraram-se 434 elevações (31,4% da área) das quais 24,3% apresentaram vegetação lenhosa. A profundidade do lençol freático sob os murundus com vegetação lenhosa variou de 99,2 a 206,8cm. O solo estudado apresentou baixo teor de bases trocáveis...

A Conceptual Framework for Soil management and its effect on Soil Biodiversity in Organic and Low Input Farming
Provedor de dados: Organic Eprints
Autores: Koopmans, Dr. C.J.; Smeding, Dr. F.W.
Learning how to manage beneficial soil biological processes may be a key step towards developing sustainable agricultural systems. We designed a conceptual framework linking soil management practices to important soil-life groups and soil fertility services like nutrient cycling, soil structure and disease suppression. We selected a necessary parameter set to gain insight between management, soil life and soil support services. The findings help to develop management practices that optimise yields, soil fertility and  biodiversity in organic farming.

A conceptual framework for the evolutionary selection of biologically &amp;#x27;essential&amp;#x27; elements
Provedor de dados: Nature Precedings
Autores: Mark Conyers.
Standard texts dutifully list 16 essential elements for plant growth, yet the literature indicates that the boundary between essential and nonessential nutrients for plants is not always clear. When animals and &amp;#x27;lower&amp;#x27; organisms are considered, the team of 16 is considerably expanded and the notion of essentiality is blurred. Why are some elements more important than others to plants and to organisms in general? Here I propose three criteria by which elements might have been selected in the development of organisms: low atomic weight, at least modest abundance, and ease of assembly into complex structures. Assembly of the structural elements C, N, S, P, and O is based on valency and ionic potential. The selection of monovalent elements...

A condição das coxas anteriores, do meso-catepímero e do meso-catepisterno dos Tabanidae (Diptera) e sua possível importância na classificação
Provedor de dados: Zoologia
Autores: Bernardi,Nelson.
The condition of certain neglected structures and their possible importance to the classification of the family Tabanidae are studied. The front coxae are considered as belonging to two types: 1) short and robust; 2) long and slender. The posterior edge of the meso-katepimeron presents two conditions: 1) without projection, 2) with backward projection. Similar conditions are found in the meso-Katepisternum, but with intermediate conditions. These characters are discussed in relation to the system proposed for the family by Mackerras. Conditions 1 and 2 of the former two structures separate, respectively, the Pangoniinae and Scepsidinae from the Chrysopsinae and Tabaninae. Condition 2 of the third structure seems to be developing independently in different...

A condition of cooperation. Games on network
Provedor de dados: Nature Precedings
Autores: Tomohiko Konno.
Natural selection is often regarded as a result of severe competition. Defect seems beneficial for a single individual in many cases.However, cooperation is observed in many levels of biological systems ranging from single cells to animals, including human society. We have yet known that in unstructured populations, evolution favors defectors over cooperators. On the other hand, there have been much interest on evolutionary games^1,2^ on structured population and on graphs^3-16^. Structures of biological systems and societies of animals can be taken as networks. They discover that network structures determine results of the games. Together with the recent interest of complex networks^17,18^, many researchers investigate real network structures. Recently...

タイリクモモンガPteromys volansは，フィンランドやエストニア，韓国などでは森林分断化の影響による個体数の減少が危惧されている．北海道の十勝地方においても，過去の森林分断化によって生息地が減少した上に，現在でもさらに生息地の分断化・減少が進行している．本種に対する森林分断化の影響を評価するには，生息確認方法を確立し，生息状況をモニタリングする必要がある．本研究では，糞による簡便かつ効率的な生息確認方法を確立するために，糞が頻繁に発見される場所の特徴や糞の発見効率を検討した．11ヶ所の樹林地（面積0.42–13.69 ha）において，それぞれ10 mの調査ラインをランダムに12本引き，両側4 m（片側2 m）の範囲で糞の有無を確認した．全ての樹林地で本種の糞が発見され，1ヶ所の樹林地あたりの発見糞塊数は平均9.7個，発見ライン数は平均6.2本であった．糞は胸高直径が太い樹木の近くでよく発見され，胸高直径24 cm以上の樹木から20 cm以内の範囲で糞を探すことが効率的であることがわかった．一方で，樹林面積は糞の発見ライン数に影響しなかった．そのため，樹林面積の大きさによって，調査努力量を変える必要はないと考えられた．本調査の結果から，面積に関わらず1ヶ所の樹林地につき5本程度のラインを引いて糞を探すことで，簡便かつ効率的に本種の生息を確認できることがわかった．

A Conjoint Analysis of Public Preferences for Agricultural Land Preservation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duke,   Joshua M.; Ilvento,   Thomas W.
Public preferences for the nonmarket services of permanently preserved agricultural land are measured and compared using conjoint analysis. The results from a survey of 199 Delawareans suggest environmental and nonmarket-agricultural services are the most important preserved-land attributes. Results also suggest that open space associated with wetlands on farms is neither an amenity nor a disamenity. On the margin, preserved parcels with agricultural and environmental attributes provide net benefits, which may exceed $1,000,000 for a 1,000-acre parcel. Preserved forestland provides benefits per acre that are statistically equivalent to cropland, though forestland may be less expensive to preserve.

A conjugate of an anti-midkine single-chain variable fragment to doxorubicin inhibits tumor growth
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Zhao,Shuli; Zhao,Guangfeng; Xie,Hao; Huang,Yahong; Hou,Yayi.
Doxorubicin (DOX) was conjugated to a single-chain variable fragment (scFv) against human midkine (MK), and the conjugate (scFv-DOX) was used to target the chemotherapeutic agent to a mouse solid tumor model in which the tumor cells expressed high levels of human MK. The His-tagged recombinant scFv was expressed in bacteria, purified by metal affinity chromatography, and then conjugated to DOX using oxidative dextran (Dex) as a linker. The molecular formula of this immunoconjugate was scFv(Dex)1.3(DOX)20. In vitro apoptosis assays showed that the scFv-DOX conjugate was more cytotoxic against MK-transfected human adenocarcinoma cells (BGC823-MK) than untransfected cells (55.3 ± 2.4 vs 22.4 ± 3.8%) for three independent experiments. Nude mice bearing...

A conservationist approach on environmental diagnosis of ground use in the Iguatemi river basin, Mato Grosso do Sul State, Brazil - doi: 10.4025/actascibiolsci.v34i3.9001
Provedor de dados: Acta Scientiarum: Biological Sciences
Autores: Souto, Marco Antonio Gomes; Instituto Reserva Natural.
Landscape Ecology is a contemporary approach in conservation studies in which, coupled to the development and use of GIS-based tools, provides new methods for the analysis of forest fragments. Based on these new approaches, the environmental assessment of ground use in the Iguatemi river basin Mato Grosso do Sul State, Brazil is provided through conservation-based flora and ecology aspects. A regional map of ground use with field-collected data using Rapid Ecological Assessment methodology and digital satellite images was prepared. AER analysis showed a highly impacted region featuring intense transformation in ground use with a conversion of 87% of native forest into grazing and agriculture land. The general situation is inconsistent with APA guidelines,...

A Conservative Model for Nonlinear Dynamics in a Stratified, Rotating Fluid
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Filatoff, Nicolas; Carton, Xavier.
We present a set of equations describing the nonlinear dynamics of flows constrained by environmental rotation and stratification (Rossby numbers Ro∈[0.1,0.5] and Burger numbers of order unity). The fluid is assumed incompressible, adiabatic, inviscid and in hydrostatic balance. This set of equations is derived from the Navier Stokes equations (with the above properties), using a Rossby number expansion with second order truncation. The resulting model has the following properties: 1) it can represent motions with moderate Rossby numbers and a Burger number of order unity; 2) it filters inertia-gravity waves by assuming that the divergence of horizontal velocity remains small; 3) it is written in terms of a single function of space and time (pressure,...

A conservative region of the mercuric reductase gene (merA) as a molecular marker of bacterial mercury resistance
Provedor de dados: Brazilian Journal of Microbiology
Autores: Sotero-Martins,Adriana; Jesus,Michele Silva de; Lacerda,Michele; Moreira,Josino Costa; Filgueiras,Ana Luzia Lauria; Barrocas,Paulo Rubens Guimarães.
The most common bacterial mercury resistance mechanism is based on the reduction of Hg(II) to Hg0, which is dependent of the mercuric reductase enzyme (MerA) activity. The use of a 431 bp fragment of a conservative region of the mercuric reductase (merA) gene was applied as a molecular marker of this mechanism, allowing the identification of mercury resistant bacterial strains.

The author gives a recapitulation of the families of the Aphyllophorales. He is inclined to recognize 21: the families he is not (yet) prepared to uphold are discussed. The synonymy of the order and the families above the rank of genus is listed, but it is avowedly incomplete. The treatment of each family does not go further than the mention of the included genera, but through selected references cited for each genus in a special list, an introduction to the separate genera is provided. An introductory chapter contains some general remarks and discusses a number of terms used in connection with the treatment of the families. New taxa are, Brachybasidiales, Hericiaceae, Punctulariaceae, Asterostromatoideae, Pteruloideae, while the name Septobasidiales Couch...

A conspectus og the genus Allophylus (Sapindaceae). The problem of the complex species
Provedor de dados: Naturalis Digital Academic Repository
Autores: Leenhouts, P.W.
Allophylus, at present with c. 255 accepted species, is considered as one of the largest genera of the Sapindaceae. It is distributed throughout the tropics of the Old and the New World, and shows a wide ecological range. Although somewhat variable in vegetative characters, there is a striking homogeneity in fertile characters, by which the generic disposition is easily spotted all over the world. Specific delimitation is renowned difficult in this genus (chapter 2). An analysis of the revision given by Radlkofer in his monograph of the Sapindaceae in ‘Das Pflanzenreich’, Heft 98 (1931—34) reveals that the characters, accepted by him as diagnostic, are all extremely vague, and often grading or overlapping. Of course, the species defined by these characters...

Autores: Alves,M.F.; Araujo,M.C.; Juliano,M.A.; Oliveira,E.M.; Krieger,J.E.; Casarini,D.E.; Juliano,L.; Carmona,A.K.
A continuous assay using internally quenched fluorescent peptides with the general sequence Abz-peptidyl-(Dnp)P-OH (Abz = ortho-aminobenzoic acid; Dnp = 2,4-dinitrophenyl) was optimized for the measurement of angiotensin I-converting enzyme (ACE) in human plasma and rat tissues. Abz-FRK(Dnp)P-OH, which was cleaved at the Arg-Lys bond by ACE, was used for the enzyme evaluation in human plasma. Enzymatic activity was monitored by continuous recording of the fluorescence (lambdaex = 320 nm and lambdaem = 420 nm) at 37ºC, in 0.1 M Tris-HCl buffer, pH 7.0, with 50 mM NaCl and 10 µM ZnCl2. The assays can be performed directly in the cuvette of the fluorimeter and the hydrolysis followed for 5 to 10 min. ACE measurements in the plasma of 80 healthy patients with...

A continuous labelling approach to recover photosynthetically fixed carbon in plant tissue and rhizosphere organisms of young beech trees (Fagus sylvatica L.) using 13C depleted CO2
Provedor de dados: Organic Eprints
Autores: Esperschütz, J.; Gattinger, A.; Buegger, F.; Lang, H.; Munch, J.; Schloter, M.; Winkler, J.
A continuous labelling experiment using 13C-CO2 was set up in open-top chambers in order to follow fluxes of assimilates from the plant into the rhizosphere. Labelling was performed for one growing season by adding low amounts of CO2 depleted in 13C to the atmosphere of the open-top chambers, resulting in a difference of ∆ 13C 5‰ V-PDB compared to ambient conditions. The label was recovered in both plant parts and soil microbial communities, analysed via phospholipid fatty acid (PLFA) side chains. PLFA 18:2ω6,9 showed a significant incorporation of the 13C label in October, indicating that fungi utilized plant derived carbon. In bacterial PLFA no label incorporation was detected, probably due to a lower use of rhizodeposits or a preference to older carbon...

Volcanic ash preserved in marine sediment sequences is key for independent synchronization of palaeoclimate records within and across different climate archives. Here we present a continuous tephrostratigraphic record from the Labrador Sea, spanning the last 65.5 ka, an area and time period that has not been investigated in detail within the established North Atlantic tephra framework. We investigated marine sediment core GS16]204] 22CC for increased tephra occurrences and geochemically analysed the major element composition of tephra shards to identify their source volcano(es). In total we observed eight tephra zones, of which five concentration peaks show isochronous features that can be used as independent tie]points in future studies. The main...

The Brazilian Cerrado is the richest savanna in the world. It is also one of the biomes more threatened in the country and a hotspot for conservation priorities. The main causes of deforestation in Cerrado are agricultural practices, livestock and charcoal production. Although charcoal has a minor impact, its consumption represents the deforestation of 16.000 Km² of the Cerrado. To contribute for the biomes's conservation it is very important to improve forestry supervision. Thus, in this work we present the macroscopic characterization of charcoal from 25 Cerrado's species. We simulate the real conditions of forest controllers by using the magnifications of 10x, 25x and 65x. Likewise, the charcoals micrographs are all of transverse sections due to the...

A contribution to the phytogeography of the Angmagssalik area, East Greenland, with special reference to Chionophily
Provedor de dados: Naturalis Digital Academic Repository
Autores: Molenaar, J.G. de.
As delimited by Polunin (1951), the Arctic is situated on the Northern hemisphere North of (1) a line 50 miles North of the coniferous forest line, (2) the Northern limit of microphanerophytic growth, or (3) the Nordenskjöld line, according to the formula V = 9-0,1K. According to this delimination the whole of Greenland belongs to the arctic region. Within the Arctic a subdivision in low- and high-arctic regions is usually recognized. Larsen (1960) marks this transition on the East coast of Greenland near Cape Dalton. Low-arctic East Greenland thus stretches from 60° to 69°30' N. lat. The Angmagssalik area in Southeast Greenland ranges from circa 65° to 67°20' N. lat. Between the Sermilik and the Kangerdlugssuatsiak fjords to the West and East, Denmark...

2. Nereidae 1). Nereis (Platynereis) striata (Schm.). (Mastigonereis striata Schm.). Of this species several specimens were collected in Table bay, where they were found for the first time by Schmarda 2) and afterwards met with by Willey 3). Unfortunately the description of the species is rather short and incomplete and the synonimy somewhat dubious; therefore I think it not superfluous to give a detailed account of them, especially while an epitocous male was among them. The specimens are rather small, measuring about 30 mm. in length, whereas the number of segments amounts to 70. The specimens of Schmarda and of Willey were somewhat larger, measuring 50 mm. in length, with about 80 segments. Nereis striata is characterized by a conspicuous coloration,...

1. Amphinomidae and Aphroditidae. Professor Max Weber, during a short stay in South Africa in 1894, made a small collection of Annelids, which he kindly handed me over for examination. As I found among them some species, which for the first time are mentioned from this interesting region, where the fauna'sof the Atlantic and the Indo-Pacific meet each other, it will not be without interest to publish a short note about them. Euphrosyne capensis Kinb. 1). (— polybranchia Schm.) 2).

Autores: Leme,Paulo Henrique Montagnana Vicente; Aguiar,Bruno Henrique; Rezende,Daniel Carvalho de.
Resumo: O desenvolvimento de novos Arranjos Produtivos Locais (APLs) no Brasil é um tema de extrema importância no atual contexto econômico e social brasileiro. As Indicações Geográficas (IG) surgem com o objetivo de proteger e valorizar produtos e serviços típicos de uma região. O resultado é que estes APLs que buscam reconhecimento de origem necessitam desenvolver aspectos ligados à governança local e à coordenação de relacionamentos e interesses diversos. O objetivo deste trabalho foi estudar um APL consolidado na produção de café, o do Cerrado Mineiro, em busca de aspectos estratégicos que expliquem seu sucesso e, através de uma pesquisa-ação, reproduzir as categorias estratégicas encontradas na articulação estratégica da construção da IG da região...

Prostaglandin F-2 alpha (PGF(2 alpha)) is the primary luteolysin in the cow, and luteal endothelin-1 (ET-1) interacts with PGF(2 alpha) during the process of luteolysis. In contrast, a developing corpus luteum (CL) is refractory to exogenous administration of PGF(2 alpha). Thus, the present study was aimed to investigate the functional relationship between ET-1 and PGF(2 alpha) in the mid-CL (PGF(2 alpha)-sensitive) and early-CL (PGF(2 alpha)-refractory). In the mid-CL model, cows (n = 6/treatment) were assigned to receive one of five types of treatments on day 10 of the estrous cycle: (1) an injection of saline; control, (2) a 500 jig of PGF2. analogue (sufficient dose to induce luteolytis); full-PG, (3) an intraluteal injection of 0.25 mg ET-1; ET-1, (4)...

A cooperative and specific DNA-binding mode of HIV-1 integrase depends on the nature of the metallic cofactor and involves the zinc-containing N-terminal domain
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Carayon, Kevin; Leh, Herve; Henry, Etienne; Simon, Francoise; Mouscadet, Jean-francois; Deprez, Eric.
HIV-1 integrase catalyzes the insertion of the viral genome into chromosomal DNA. We characterized the structural determinants of the 3'-processing reaction specificity-the first reaction of the integration process-at the DNA-binding level. We found that the integrase N-terminal domain, containing a pseudo zinc-finger motif, plays a key role, at least indirectly, in the formation of specific integrase-DNA contacts. This motif mediates a cooperative DNA binding of integrase that occurs only with the cognate/viral DNA sequence and the physiologically relevant Mg(2+) cofactor. The DNA-binding was essentially non-cooperative with Mn(2+) or using non-specific/random sequences, regardless of the metallic cofactor. 2,2'-Dithiobisbenzamide-1 induced zinc ejection...

This study investigates the reasons which lead the companies to keep simultaneous vertical integrated, third part and hybrid distribution channels. Companies establish different coordination structures, the organizational arrangements, which determine how the agents involved cooperate to the development of distribution activities, according to Transaction Cost Economics and Dynamic Competence. Even choosing different distribution channels, why the company does not establish one single organizational arrangement? What factors may justify the establishment of different arrangements? Possible explanations to those questions have been pointed out in multiple distribution channels. The empirical research indicates that firms establish multiple efficient...

Realizaram-se comparações entre as sementes dos cultivares Mundo Novo de Coffea arabica, cujo endosperma é verde, com as do cultivar Cera, dessa espécie, de endosperma amarelo, com o objetivo de determinar os componentes responsáveis por aquela cor. Nas análises de clorofilas, flavonóides, diterpenos totais, ácido clorogênico e íons Mg, Ca, K, Fe e B, nenhuma diferença foi verificada entre os dois cultivares, sugerindo que a coloração verde se deva à presença de outros componentes ou que o 'Cera' apresente um componente que não ocorre no 'Mundo Novo' e que inibe o desenvolvimento da cor verde no seu endosperma.

A Correction for the Thermal Mass-Induced Errors of CTD Tags Mounted on Marine Mammals
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mensah, Vigan; Roquet, Fabien; Siegelman-charbit, Lia; Picard, Baptiste; Pauthenet, Etienne; Guinet, Christophe.
The effect of thermal mass on the salinity estimate from conductivity-temperature-depth (CTD) tags sensor mounted on marine mammals is documented, and a correction scheme is proposed to mitigate its impact. The algorithm developed here allows for a direct correction of the salinity data, rather than a correction of the sample's conductivity and temperature. The amplitude of the thermal mass-induced error on salinity and its correction are evaluated via comparison between data from CTD tags and from Sea-Bird Scientific CTD used as a reference. Thermal mass error on salinity appears to be generally O(10(-2)) g kg(-1), it may reach O(10(-1)) g kg(-1), and it tends to increase together with the magnitude of the cumulated temperature gradient (T-HP) within the...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Arraes,L.C.; de Souza,P.R.; Bruneska,D.; Castelo Filho,A.; de Souza Cavada,B.; de Lima Filho,J.L.; Crovella,S.
We report a fast (less than 3 h) and cost-effective melting temperature assay method for the detection of single-nucleotide polymorphisms in the MBL2 gene. The protocol, which is based on the Corbett Rotor Gene real time PCR platform and SYBR Green I chemistry, yielded, in the cohorts studied, sensitive (100%) and specific (100%) PCR amplification without the use of costly fluorophore-labeled probes or post-PCR manipulation. At the end of the PCR, the dissociation protocol included a slow heating from 60º to 95ºC in 0.2ºC steps, with an 8-s interval between steps. Melting curve profiles were obtained using the dissociation software of the Rotor Gene-3000 apparatus. Samples were analyzed in duplicate and in different PCR runs to test the reproducibility of...

Autores: Coady,   David P.; Parker,   Susan W.
This paper is concerned with the issue of the most cost-effective way of improving access to education for poor households in developing countries. We consider two alternatives: (1) extensive expansion of the school system (i.e., bringing education to the poor) and (2) subsidizing investment in education by the poor (i.e., bringing the poor to the education system). To this end, we evaluate the Programa Nacional de Educación, Salud y Alimentación (PROGRESA), a large poverty alleviation program recently introduced in Mexico that subsidizes education. Using double-difference regression estimators on data collected before and after the program for randomly selected control and treatment households, we estimate the relative impacts of the demand- and...

A coupled climate model simulation of Marine Isotope Stage 3 stadial climate
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brandefelt, J.; Kjellstrom, E.; Naslund, J. -o.; Strandberg, G.; Voelker, A. H. L.; Wohlfarth, B.
We present a coupled global climate model (CGCM) simulation, integrated for 1500 yr to quasi-equilibrium, of a stadial (cold period) within Marine Isotope Stage 3 (MIS 3). The simulated Greenland stadial 12 (GS12; similar to 44 ka BP) annual global mean surface temperature (T-s) is 5.5 degrees C lower than in the simulated recent past (RP) climate and 1.3 degrees C higher than in the simulated Last Glacial Maximum (LGM; 21 ka BP) climate. The simulated GS12 is evaluated against proxy data and previous modelling studies of MIS3 stadial climate. We show that the simulated MIS 3 climate, and hence conclusions drawn regarding the dynamics of this climate, is highly model-dependent. The main findings are: (i) Proxy sea surface temperatures (SSTs) are higher...

This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...

A "critical" climatic evaluation of last interglacial (MIS 5e) records from the Norwegian Sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bauch, Henning A.; Erlenkeuser, Helmut.
Sediment cores from the Norwegian Sea were studied to evaluate interglacial climate conditions of the marine isotope stage 5e (MIS 5e). Using planktic forminiferal assemblages as the core method, a detailed picture of the evolution of surface water conditions was derived. According to our age model, a step-like deglaciation of the Saalian ice sheets is noted between ca. 135 and 124.5 Kya, but the deglaciation shows little response with regard to surface ocean warming. From then on, the rapidly increasing abundance of subpolar forminifers, concomitant with decreasing iceberg indicators, provides evidence for the development of interglacial conditions sensu stricto (5e-ss), a period that lasted for about 9 Ky. As interpreted from the foraminiferal records,...

A critical evaluation of the effect of population size and phenotypic measurement on QTL detection and localization using a large F2 murine mapping population
Provedor de dados: Genetics and Molecular Biology
Autores: Li,Xinmin; Quigg,Richard J; Zhou,Jian; Xu,Shizhong; Masinde,Godfred; Mohan,Subburaman; Baylink,David J.
Population size and phenotypic measurement are two key factors determining the detection power of quantitative trait loci (QTL) mapping. We evaluated how these two controllable factors quantitatively affect the detection of QTL and their localization using a large F2 murine mapping population and found that three main points emerged from this study. One finding was that the sensitivity of QTL detection significantly decreased as the population size decreased. The decrease in the percentage logarithm of the odd score (LOD score, which is a statistical measure of the likelihood of two loci being lied near each other on a chromosome) can be estimated using the formula 1 - n/N, where n is the smaller and N the larger population size. This empirical formula has...

Food consumption patterns have received considerable attention lately, especially changes in red meat consumption. This article examines and analyzes changes in meat consumption patterns in a southern state. Differences are reported based on demographics and consumer expressed preferences. The results reaffirm the negative role of health concerns and fat on red meat consumption and the positive influence on poultry and seafood. The findings agree with related other studies and suggest that further research into the changing meat consumption patterns is warranted.

Cereal foods' production and use show substantial heterogeneity across Europe. For a category central in most EU diets, cereal foods' quality perception is, nevertheless, surprisingly understudied. With this in mind, 357 Danish, Lithuanian and Portuguese citizens were inquired about the importance of several cues and dimensions in their evaluation of the perceived quality of bread, cookies, breakfast cereals, pasta and vodka. Portuguese and Lithuanians consistently gave a significantly higher average importance to all the cues and quality dimensions considered, for all products, than their Danish counterparts. Nevertheless, respondents in all three samples found expected quality dimensions to be much more important than both extrinsic and intrinsic cues...

This paper analyzes the determinants of variation across industries in levels of intra-industry trade (IIT) for a sample of thirty-six U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focused on industry characteristics in the manufacturing sectors.  The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, economies of scope, and similarity of tariff barriers among trade partners, but negatively related to industry concentration.

ABSTRACT Meningococcal carriage is a prerequisite for invasive infection. This cross-sectional study assessed the pharyngeal carriage prevalence in healthy subjects aged 1-24 years in Embu das Artes city, São Paulo, Brazil. Pharyngeal swabs were examined for the presence of Neisseria meningitidis. The isolates were tested for different serogroups using agglutination and polymerase chain reaction. A logistic regression model assessed any independent association between Neisseria meningitidis carriage and various risk factors. A total of 87/967 subjects (9%, 95% Confidence Interval (CI): 7.3-11.0) tested positive for N. meningitidis: 6.2% (95% CI: 3.8-9.4) in 1-4 years, 8.5% (95% CI: 5.1-13.0) in 5-9 years, 12.5% (95% CI: 7.8-18.6) in 10-14 years, 12.6% (95%...

Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Nagalingam,Nabeetha A.; Adesiyun,Abiodun A.; Swanston,William H.; Bartholomew,Maria.
We determined the frequency of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, and Gram-negative enteric bacteria (GNEB) in pneumonia patients, determined the antibiograms of these pathogens, and investigated the relationship between pneumonia and selected risk factors. Sputum and demographic data were collected from 124 pneumonia patients. Sputum was cultured for S. aureus, GNEB, H. influenzae and S. pneumoniae. The disc diffusion method was used to determine resistance to eight antimicrobial agents. Among the 124 sputum samples, eight (6.5%) were positive for S. aureus, 15 (12.1%) for GNEB, two (1.6%) for S. pneumoniae and one (0.8%) for H. influenzae. Hospitals, gender, ethnicity, co-morbidities and symptoms did not...

A CssA, CssB and LTB chimeric protein induces protection against Enterotoxigenic Escherichia coli
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Bagheri,Samane; Gargari,Seyed Latif Mousavi; Rasooli,Iraj; Nazarian,Shahram; Alerasol,Masoome.
OBJECTIVES: Enterotoxigenic Escherichia coli (ETEC), a major cause of diarrhea in children under 5, is an important agent for traveler's diarrhea. Heat-labile enterotoxin (LT) and colonization factors (CFs) are two main virulence mechanisms in ETEC. CS6 is one of the most prevalent CFs consisting of two structural subunits viz., CssA, CssB, necessary for attachment to the intestinal cells.METHODS: In the present research, a chimeric trivalent protein composed of CssB, CssA and LTB was constructed. The chimeric gene was synthesized with codon bias of E. coli for enhanced expression of the protein. Recombinant proteins were expressed and purified. Mice were immunized with the recombinant protein. The antibody titer and specificity of the immune sera were...

Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: SAMPAIO, J. M. M.; RODRIGUES, J. A. S.
As áreas de melhor adaptação para mangueira são aquelas onde as estações secas e chuvosas são bem defini das. O período seco deve ocorrer bem antes do florescimento, a fim de permitir um período de repouso vegetativo á planta, e prolongar-se até a frutificação para evitar os danos causados pelo ataque da antracnose e do oídio. Após frutificação, é benéfica a ocorrência de chuva afim desestimular o desenvolvimento e impedir a queda dos frutos. A quantidade de chuva pode variar entre 500 e 2.500mn anuais, desde que atendidas as condições referidas acima.

A cytosolic class II small heat shock protein, PfHSP17.2, confers resistance to heat, cold, and salt stresses in transgenic Arabidopsis
Provedor de dados: Genetics and Molecular Biology
Autores: Zhang,Lu; Hu,Weijuan; Gao,Yike; Pan,Huitang; Zhang,Qixiang.
Abstract We cloned and characterized the full-length coding sequence of a small heat shock (sHSP) gene, PfHSP17.2, from Primula forrestii leaves following heat stress treatment. Homology and phylogenetic analysis suggested that PfHSP17.2 is a cytosolic class II sHSP, which was further supported by the cytosolic localization of transient expression of PfHSP17.2 fused with green fluorescent protein reporter. Expression analysis showed that PfHSP17.2 was highly inducible by heat stress in almost all the vegetative and generative tissues and was expressed under salt, cold, and oxidative stress conditions as well. Moreover, the expression of PfHSP17.2 in P. forrestii was detected in certain developmental growth stages. Transgenic Arabidopsis thaliana...

A Cytotaxonomic study of Viola in the Netherlands
Provedor de dados: Naturalis Digital Academic Repository
Autores: Gadella, T.W.J.
1. The chromosome numbers of 10 species of the genus Viola in the Netherlands were determined. 2. Viola riviniana has various chromosome numbers: 2n = 35, 40, 45, 46, 47 (most often 2n = 40). 3. It was not possible to find a correlation between the external morphology and the various chromosome numbers in V. riviniana. 4. Despite the variability of V. riviniana it proved impossible to divide the Dutch material into subspecies. 5. Some differential characters of V. riviniana and V. reichenbachiana are described. 6. V. canina is not variable in cytological respect in the Netherlands. 7. V. calaminaria is not related to V. lutea but to the V. tricolor complex.

A data assimilating model for estimating Southern Ocean biogeochemistry
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Verdy, A.; Mazloff, M. R.
A Biogeochemical Southern Ocean State Estimate (B-SOSE) is introduced that includes carbon and oxygen fields as well as nutrient cycles. The state estimate is constrained with observations while maintaining closed budgets and obeying dynamical and thermodynamic balances. Observations from profiling floats, shipboard data, underway measurements, and satellites are used for assimilation. The years 2008-2012 are chosen due to the relative abundance of oxygen observations from Argo floats during this time. The skill of the state estimate at fitting the data is assessed. The agreement is best for fields that are constrained with the most observations, such as surface pCO(2) in Drake Passage (44% of the variance captured) and oxygen profiles (over 60% of the...

A data set of sea surface stereo images to resolve space-time wave fields
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guimarães, Pedro Veras; Ardhuin, Fabrice; Bergamasco, Filippo; Leckler, Fabien; Filipot, Jean-francois; Shim, Jae-seol; Dulov, Vladimir; Benetazzo, Alvise.
Stereo imaging of the sea surface elevation provides unique field data to investigate the geometry and dynamics of oceanic waves. Typically, this technique allows retrieving the 4-D ocean topography (3-D space + time) at high frequency (up to 15–20 Hz) over a sea surface region of area ~104 m2. Stereo data fill the existing wide gap between sea surface elevation time-measurements, like the local observation provided by wave-buoys, and large-scale ocean observations by satellites. The analysis of stereo images provides a direct measurement of the wavefield without the need of any linear-wave theory assumption, so it is particularly interesting to investigate the nonlinearities of the surface, wave-current interaction, rogue waves, wave breaking, air-sea...

A decadal-scale Holocene sea surface temperature record from the subpolar North Atlantic constructed using diatoms and statistics and its relation to other climate parameters
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Berner, K. S.; Koc, N.; Divine, D.; Godtliebsen, F.; Moros, M.
A sediment core from Reykjanes Ridge has been studied at 10- to 50-year time resolution to document variability of Holocene surface water conditions in the western North Atlantic and to evaluate effects of Holocene ice-rafting episodes. Diatom assemblages are converted to quantitative sea surface temperatures (SST) using three different transfer functions. Spectral and scale-space methods are also applied on the records to explore variability at different timescales. Diatom assemblage and SST records clearly show that decaying remnants of the Laurentide ice sheet strongly influenced early Holocene climate in the western North Atlantic. This overrode the predominance of Milankovitch forcing, which played a key role in the development of Holocene climate in...

Traditional break-even/fed cattle price projections do not provide adequate risk information to feeders, investors, lenders, and other stakeholders interested in cattle feeding decisions. The objectives of this study were two-fold: 1) develop a spreadsheet model that could estimate the net income distribution surrounding a cattle placement decision based on historical errors of futures based price forecasts, and 2) determine whether information generated from the model can be used to improve placement and marketing decisions. To accomplish objective 1, model was developed that could estimate the income distribution around a pen of cattle under a cash speculating and short hedge pricing strategy. Distribution estimates were based on 7 alternative forecast...

A decoding method of an n length binary BCH code through (n + 1)n length binary cyclic code
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: SHAH,TARIQ; KHAN,MUBASHAR; ANDRADE,ANTONIO A. DE.
For a given binary BCH code Cn of length n = 2s - 1 generated by a polynomial  of degree r there is no binary BCH code of length (n + 1)n generated by a generalized polynomial  of degree 2r. However, it does exist a binary cyclic code C(n+1)n of length (n + 1)n such that the binary BCH code Cn is embedded in C(n+1)n. Accordingly a high code rate is attained through a binary cyclic code C(n+1)n for a binary BCH code Cn. Furthermore, an algorithm proposed facilitates in a decoding of a binary BCH code Cn through the decoding of a binary cyclic code C(n+1)n, while the codes Cn and C(n+1)n have the same minimum hamming distance.

A deductive approach to animal health planning in organic dairy farming: Method description
Provedor de dados: Organic Eprints
Autores: Selle, Margret; Hoischen-Taubner, Susanne; Sundrum, Albert.
Organic farming is often directly associated with an enhanced level of animal health and welfare. However, in spite of ongoing efforts in the fields of animal science, the animal health status in organic dairy farming does not in all respect meet consumers’ expectations. Reasons are manifold and differ considerably between farms as do the multi-factorial production diseases. Success of animal health planning highly depends on a sound diagnostic procedure at farm level and farmers’ intrinsic motivation to improve the animal health status. Both aspects are essential preconditions for the identification and implementation of the most appropriate farm-specific management measures.  The aim of this paper is to introduce a participatory and farm-centric...

Autores: Zanin,Vanclei; Bacchi,Mirian Rumenos Piedade; Almeida,Aléssio Tony Cavalcanti de.
Resumo O arroz é um alimento básico na dieta do brasileiro; contudo, o lento crescimento de seu consumo tem impactos diretos na expansão do setor. Para compreender os fatores que afetam esse consumo e suas inter-relações com outros alimentos foram estimadas, neste estudo, as elasticidades da demanda por dez alimentos nos domicílios brasileiros, utilizando dados da Pesquisa de Orçamentos Familiares 2008-2009. Para tanto, foi aplicado o modelo Quadratic Almost Ideal Demand System (Quaids) ajustado para o problema do consumo censurado e da endogeneidade das despesas. Os resultados gerais indicam que o arroz apresenta elasticidade-dispêndio menor que a unidade. A elasticidade-renda da demanda reforça esse comportamento de bem necessário, sendo mais elevada em...

Autores: Bergmans, M.
The life-cycle of the harpacticoid copepod &lt;i&gt;Tisbe furcata&lt;/i&gt; (Baird, 1837) at 18°C was studied quantitatively. Stage durations were determined by two different methods, using synchronous cohorts. Combined nauplius stages last for 80.4h; the successive copepodite stages take 23.0, 23.2, 28.0 (females) to 23.2 (males), 33.4 (females) to 24.2 (males) and 48.8 (females) to 34.7 (males) h, respectively. Females develop more slowly but more synchronously than males. Age-specific survival and fertility rates were used to calculate the stable stage distribution in an exponentially growing population. From life-table data the following demographic parameters were computed: intrinsic rate of natural increase...

The importance of U.S. exports of dry milk products is suggested by figures in the paper showing that in 2000, 17% of U.S. nonfat dry milk, 35% of dry whey, 47% of lactose, and 11% of whey protein concentrates were exported. The Gould-Villarreal study documents the decline in world trade in nonfat dry milk and expansion of world trade in whole milk powder. The paper suggests that collective product mix decisions of the U.S. dairy industry are partially out-of-sync with world demand. Other implications for U.S. dairy exporters of changes in world demand for dry milk products are discussed.

A Design and Analysis Methodology for Component-Based Real-Time Architectures of Autonomous Systems
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gobillot, Nicolas; Lesire, Charles; Doose, David.
The integration of autonomous robots in real applications is a challenge. It needs that the behaviour of these robots is proved to be safe. In this paper, we focus on the real-time software embedded on the robot, and that supports the execution of safe and autonomous behaviours. We propose a methodology that goes from the design of component-based software architectures using a Domain Specific Language, to the analysis of the real-time constraints that arise when considering the safety of software applications. This methodology is supported by a code generation toolchain that ensures that the code eventually executed on the robot is consistent with the analysis performed. This methodology is applied on a ground robot exploring an area. Categories (2), (3)

A determinação da capacidade de troca de cátions do solo e de argilas por meio da troca isotópica com cálcio radioativo
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Catani,R. A.; Perez,J. T.
O presente trabalho descreve a determinação da capacidade de troca de cátions (CTC) do solo e de argilas, através da troca isotópica com cálcio radioativo, 20Ca45. Foi determinada a CTC de oito amostras de solo e de quatro de argilas, tendo sido feitas 5 pesagens de cada amostra de cada um dos materiais, a fim de se avaliar a precisão do método. O cálculo da CTC foi feito mediante a expressão: X = a1/a2 c - c a1 = atividade específica do cálcio da solução de equilíbrio antes de entrar em contato com o solo. a2 = atividade específica do cálcio da solução de equilíbrio após o contato com o solo. c = número de e.mg de cálcio da solução de equilíbrio e calculado para 100g de solo. X = capacidade de troca de cations em e.mg por 100g de solo.

O presente trabalho relata os métodos e técnicas de determinação do teor total e do teor solúvel, em diversas soluções, do molibdênio do solo. O extrato do solo para a determinação do teor total de molibdênio foi preparado atacando-se as amostras com água régia, ácido sulfúrico (1 + 1) e ácido perclórico (1 + 1), Em seguida o molibdênio foi determinado pelo método colorimétrico do tiocianato. A extração do teor solúvel de molibdênio do solo, com diversas soluções extratoras, mostrou que talvez uma solução 0,03 N de NH4F em H2SO4 0,1 N, possa ser usada em análises de rotina para extração do molibdênio do solo, em substituição aos extratores e às técnicas mais morosas, utilizadas para se avaliar o teor de molibdenio solúvel.

The main object of the present paper consists in giving formulas and methods which enable us to determine the minimum number of repetitions or of individuals necessary to garantee some extent the success of an experiment. The theoretical basis of all processes consists essentially in the following. Knowing the frequency of the desired p and of the non desired ovents q we may calculate the frequency of all possi- ble combinations, to be expected in n repetitions, by expanding the binomium (p-+q)n. Determining which of these combinations we want to avoid we calculate their total frequency, selecting the value of the exponent n of the binomium in such a way that this total frequency is equal or smaller than the accepted limit of precision n/pª{ 1/n1 (q/p)n +...

A deterministic population dynamics model to study the distribution of a benthic bivalve with planktonic larvae (Paphia rhomboides) in the English Channel (NW Europe)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Savina, Marie; Menesguen, Alain.
This paper describes the development of a modelling framework to study the distribution in the English Channel of a benthic bivalve with planktonic larvae, Paphia rhomboides. Age-structured population dynamics and growth models are linked together to a compartmental transport and NPZ (Nutrients-Phytoplankton-Zooplankton) model. Used in a spin-up mode, i.e. with identical environmental forcing from a year to the next, this deterministic model converges to the same steady state whatever the initial conditions, after 15-30 years of simulation. Important features of the P. rhomboides distribution are reproduced, particularly its high abundance in the GNB (Golfe Normand-Breton) and its almost complete absence in the Western Channel. The results are discussed in...

Autores: Rosa,Artur J.M.; Bijma,Piter; Oliveira,Henrique N.; Lôbo,Raysildo B.; van Arendonk,Johan A.M.
We used deterministic simulation of four alternative multiple ovulation and embryo manipulation (MOET) closed nucleus schemes to investigate the benefits of using marker-assisted selection (MAS) of Nellore (Bos indicus) beef cattle embryos prior to transplantation to reduce the age at first calving (AFC). We found that MAS resulted in increased genetic gain as compared to selection without AFC quantitative trait loci (AFC-QTL) information. With single-stage selection the genetic response (GR) increased as follows: GR = 0.68% when the AFC-QTL explained 0.02 of the AFC additive genetic variance (sigma2A); GR = 1.76% for AFC-QTL explaining 0.05 sigma2A; GR = 3.7% for AFC-QTL explaining 0.1 sigma2A; and GR = 55.76% for AFC-QTL explaining 0.95 sigma2A.

As part of developing an international network of community-based ecosystem approaches to health, a project was undertaken in a densely populated and socio-economically diverse area of Kathmandu, Nepal.  Drawing on hundreds of pages of narrative reports based on surveys, interviews, secondary data, and focus groups by trained Nepalese facilitators, the authors created systemic depictions of relationships between multiple stakeholder groups, ecosystem health, and human health. These were then combined to examine interactions among stakeholders, activities, concerns, perceived needs, and resource states (ecosystem health indicators). These qualitative models have provided useful heuristics for both community members and research scholars to understand the...

Provedor de dados: Revista Chilena de Historia Natural
Autores: GONZÁLEZ,ALEJANDRA; SANTELICES,BERNABÉ.
In late 2001 and early 2002, a dichotomous species of Codium appeared colonizing the low intertidal and shallow subtidal bottoms of Caldera Bay, northern Chile (27° 03’ S, 70° 51’ W). Due to the ecological and economic impact the species is having in Caldera Bay and its potential spread along the Chilean coastline, we studied the taxonomic identity of the species and examined its relationships with other dichotomous species of Codium reported for temperate Pacific South America. Morphological analyses suggest that the seaweeds from Caldera Bay belong to Codium fragile (Suringar) Hariot. Not only is there strong agreement in internal and external morphological characters, but among all the species reported for Peru and Chile, this is the only one exhibiting...

A 'DIFFERENTIAL' DIFFERENTIAL DEMAND SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mancuso,   Anthony J.
Traditionally, estimation of demand systems is predicated on the validity of several axioms of consumer behavior. While such abstractions make empirical work easier, they can also overlook important economic behavior. Because the price of a good does not reflect the total cost of purchase, there is reason to believe that consumer responses to changes in price are not continuous. Utilizing a regime switching model, we show that there are indeed important threshold effects, and that these effects bias elasticity estimates toward zero.

A diminuição do desmatamento na Amazônia brasileira: apoiar o manejo florestal familiar.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: SIST, P.; MAZZEI, L.; SABLAYROLLES, P.
Na Amazônia brasileira, o desmatamento anual vem diminuindo desde 2004, passando de 27.000 km², ele passou para 4.650 km2 em 2011-2012, uma cifra que está próxima da meta do plano nacional de luta contra a mudança climática para 2020, fixada em 3.900 km2. Até 2008, esta diminuição podia ser explicada pela redução das cotações mundiais /dos produtos agrícolas, na medida em que havia menos incentivo para desmatar. Mas, desde então, essa redução vem se mantendo apesar das cotações, o que mostra o impacto do Programa de Prevenção e Controle do Desmatamento na Amazônia, lançado em 2004.

No contexto do histórico de uso e ocupação das terras do Estado de São Paulo, que resultou na perda quase total de suas florestas originais e degradação dos remanescentes, as atividades agropecuárias são identificadas como potenciais condicionantes pela crescente expansão ocorrida nas últimas décadas. Por outro lado, levantamentos atuais, como o realizado pelo Instituto Florestal de São Paulo, demonstram um incremento na área mapeada como vegetação nativa do Estado (ZORZETTO, 2010), com curva ascendente similar às formulações recentes da Teoria da Transição Florestal (RUDEL, 1998; RUDEL et al., 2005). De acordo com essa Teoria, os estoques florestais mudam de modo previsível, com o decréscimo da taxa de desflorestamento e aumento da taxa de regeneração...

Autores: GARCIA,MAURÍCIO S.; PRETTO,FLÁVIO A.; DIAS-DA-SILVA,SÉRGIO; MÜLLER,RODRIGO T.
Abstract: Discoveries in Carnian-aged rocks are establishing a rich and diverse dinosaurian fauna at the so-called ‘dawn of the age of dinosaurs’ in the Late Triassic of Western Gondwana. Accordingly, Brazilian strata from the Candelária Sequence have contributed extensively to this trend. Here, we present a new dinosaurian specimen (CAPPA/UFSM 0200) from this geological unit. The material was collected at a fossiliferous site that had no previous record of dinosaurs. Our specimen comprises a single ilium, which we describe in detail. Its anatomy is consistent with Carnian sauropodomorph dinosaurs, but differs from coeval specimens by several features, although we do not discard the possibility of these features being the result of intraspecific variation....

A di-O-dihydrogeranylgeranyl glycerol from Thermococus S 557, a novel ether lipid, and likely intermediate in the biosynthesis of diethers in Archaea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gonthier, Isabelle; Rager, Marie-noëlle; Metzger, Pierre; Guezennec, Jean; Largeau, Claude.
The lipids of a deep-sea hydrothermal vent arch ae on, Thermococcus S 557, were isolated, purified and structurally determined. Based on acid methanolysis and spectroscopic studies, the polar lipids were shown to comprise diphytanyl glycerol and dibiphytanyl diglycerol, typical membrane lipids of Arch aea. From the neutral lipids, 2,3-di-O-dihydro-14,15-geranylgeranyl glycerol was isolated. This novel ether lipid is, very likely, a close intermediate in the biosynthesis of diphytanyl glycerol diether in Arch aea.

A Direct Anatomical Study of the Morphology and Functionality of Disco-malleolar and Anterior Malleolar Ligaments
Provedor de dados: International Journal of Morphology
Autores: Ramírez Aristeguieta,Luis Miguel; Ballesteros Acuña,Luis Ernesto; Sandoval Ortiz,German Pablo.
The disco-malleolar and anterior malleolar ligaments are common to the middle ear, the temporomandibular joint and the jaw, all of them sharing a common embryological origin; these ligaments' morphometric and functional aspects were studied in 23 temporal bones. Experimental design: The epitympanum roof and the temporomandibular joint roof were elevated by micro-dissection of the middle cranial fossa, exposing both disco-malleolar and anterior malleolar ligaments and their association with the malleus, the temporomandibular joint disc and the mandibular lingula. Principal observations: Both ligaments start in the malleus and take anterior and divergent routes towards the temporomandibular joint and lingula, passing through Huguier's canal. The...

A direct contact between astrocyte and vitreous body is possible in the rabbit eye due to discontinuities in the basement membrane of the retinal inner limiting membrane
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Haddad,A.; Salazar,J.J.; Laicine,E.M.; Ramírez,A.I.; Ramírez,J.M.; Triviño,A.
Different from most mammalian species, the optic nerve of the rabbit eye is initially formed inside the retina where myelination of the axons of the ganglion cells starts and vascularization occurs. Astrocytes are confined to these regions. The aforementioned nerve fibers known as medullated nerve fibers form two bundles that may be identified with the naked eye. The blood vessels run on the inner surface of these nerve fiber bundles (epivascularization) and, accordingly, the accompanying astrocytes lie mostly facing the vitreous body from which they are separated only by the inner limiting membrane of the retina. The arrangement of the astrocytes around blood vessels leads to the formation of structures known as glial tufts. Fragments (N = 3) or whole...

A direct determination of the World Ocean barotropic circulation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Verdiere, Alain Colin; Ollitrault, Michel.
The time-mean Argo float displacements and the World Ocean Atlas 2009 temperature–salinity climatology are used to obtain the total, top to bottom, mass transports. Outside of an equatorial band, the total transports are the sum of the vertical integrals of geostrophic- and wind-driven Ekman currents. However, these transports are generally divergent, and to obtain a mass conserving circulation, a Poisson equation is solved for the streamfunction with Dirichlet boundary conditions at solid boundaries. The value of the streamfunction on islands is also part of the unknowns. This study presents and discusses an energetic circulation in three basins: the North Atlantic, the North Pacific, and the Southern Ocean. This global method leads to new estimations of...

A Discriminant Analysis of Factors Associated with The Adoption Of Certified Organic Farming By Smallholder Farmers in Kwazulu-Natal, South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kisaka-Lwayo,   Maggie.
Discriminant analysis was used to identify the characteristics that distinguish between fully-certified organic, partially-certified organic and non-organic farmers in Umbumbulu district, KwaZulu-Natal (KZN), South Africa (SA) during October- November 2004. 200 farmers interviewed were drawn by purposively selecting the 151 members of the Ezemvelo Farmers’ Organisation (EFO), and by random sampling 49 non-organic farmers in wards neighbouring EFO. Results from the two estimated discriminant functions suggested that farmers with higher household sizes, incomes, input costs per hectare and number of chickens owned, locations further from innovators and less risk aversion were more likely to be certified as organic. Household location should be considered in...

A discussion of norms for S supply in organic farming based on content in forage and ruminant performance in Norway
Provedor de dados: Organic Eprints
Autores: Hansen, Sissel; Bakken, Anne Kjersti.
The content of sulphur (S) in grassland on 27 Norwegian organic farms with dairy or sheep production was investigated in 2001 and 2002. The forage content of S was below the norms (2 g S kg DM-1) for both plants and animals in a large proportion of the samples. The average S content in forage at dairy farms was 1.4 g S kg DM-1 and at sheep farms 1.5 g. Even on grasslands with low plant S content (&lt;1 g S kg DM-1), S-fertilization did not increase yields and increased the plants’ S content only very slightly. No indications of S deficiency were observed on the dairy farms. For one sheep farm with a forage S content of 1.1 ± 0.1g S kg DM-1, brittle and short winter wool was reported.

A discussion of the size of recent red deer (Cervus elaphus L.) compared with prehistoric specimens
Provedor de dados: Naturalis Digital Academic Repository
Autores: Walvius, M.R.
Red deer ( Cervus elaphus L.) are known from many prehistoric sites in Western Europe; a number of these are usually of great size as compared with contemporary animals. This essay is an attempt to summarize the literature concerning the size of the prehistoric red deer in comparison with the recent species and to discuss the different influences of the habitat (extent and character of the biotope, food, climate) on the dimensions of red deer. It is the intention that it should attribute to a better understanding of the factors that may have caused the great size of many prehistoric red deer and to try and find out if a similarity between the variation during the course of postglacial times and the local variation in relation to the habitat exists.

A Discussion on Armington Trade Substitution Elasticities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McDaniel,   Christine A.; Balistreri,   Edward J.
Applied partial and general equilibrium models used to examine trade policy are almost universally sensitive to trade elasticities. Indeed, the Armington elasticity, the degree of substitution between domestic and imported goods, is a key behavioral parameter that drives the quantitative, and sometimes the qualitative, results that policymakers use. While standard transparent approaches to econometric estimation of these elasticities have been offered for the last 30 years, the estimates are viewed as too small by many trade economists. A few robust findings emerge from the econometric literature: (1) more disaggregate analyses find higher elasticities, (2) long-run estimates are higher than short-run estimates, and (3) time series analyses generally find...

A distal 140 kyr sediment record of Nile discharge and East African monsoon variability
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ehrmann, Werner; Schmiedl, Gerhard; Seidel, Martin; Krueger, Stefan; Schulz, Hartmut.
Clay mineral assemblages in a sediment core from the distal Nile discharge plume off Israel have been used to reconstruct the late Quaternary Nile sediment discharge into the eastern Mediterranean Sea (EMS). The record spans the last ca. 140 kyr. Smectite abundances indicate the influence of the Blue Nile and the Atbara River that have their headwaters in the volcanic rocks of the Ethiopian Highlands. Kaolinite abundances indicate the influence of wadis, which contribute periodically to the suspension load of the Nile. Due to the geographical position, the climate and the sedimentary framework of the EMS is controlled by two climate systems. The long-term climate regime was governed by the African monsoon that caused major African humid periods (AHPs) with...

A distinctive new cloud-forest rodent (Hystricognathi: Echimyidae) from the Manu Biosphere Reserve, Peru
Provedor de dados: Mastozoología Neotropical
Autores: Patterson,Bruce D.; Velazco,Paul M.
Recent surveys in Peru 's Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of "brush-tailed tree rats" previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. While the inclusion of the new taxon does not resolve the "star phylogeny" which underlies the echimyid radiation, it identifies the Andes as a possible theatre for the evolution of some soft-haired members of the group. The new species is described and a revised diagnosis of the...

A diversified organic pork production – presentation of a concept based on seasonal outdoor rearing of very small entire males
Provedor de dados: Organic Eprints
Autores: Kongsted, A.G.; Hermansen, J.E.; Claudi-Magnussen, C.; Andersen, B.H.
The risk of boar taint in entire males is supposed to increase with increased age and weight. Thus, a method to reduce this risk may be to slaughter the pigs at a low age and weight. This strategy is investigated as part of a new concept for organic pig production. It is hypothesised that organic pork has to differ markedly from conventional in order to overcome the heavy price competition. A seasonal outdoor rearing system based on production of small entire males, large female pigs and sows slaughtered after their first litter is believed to be a feasible strategy for producing organic pork with high credibility and superior eating quality. The study included a traditional breed, the Danish Black-Spotted. 17 gilts farrowed in April. Within the first week...

A DOUBLE HURDLE APPROACH TO EVALUATING NON-RESIDENTIAL WILDLIFE WATCHING IN THE UNITED STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diagne,   Assane; Lavergne,   David R.; Olatubi,   Williams O.
In 1996, over 62 million U.S. residents participated in wildlife watching and spent in excess of 29 billion dollars in this recreational activity. Wildlife watching can be defined as the observation, study, and enjoyment of natural areas and its wild fauna and flora. Residential wildlife watching takes place within one mile of the participant's residence and is often an incidental or secondary activity. Non-residential wildlife watching refers to recreation taking place at a distance of at least one mile from the participant's residence. In recent years, a sharp decline in the number of wildlife watchers has been noted.  Between 1991 and 1996, the number of wildlife watchers decreased by 17 percent. During this time interval, the largest decline in...

A double-hurdle model of Irish households' foodservice expenditure patterns
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Keelan,   Conor D.; Henchion,   Maeve M.; Newman,   Carol F.
The aim of this paper is to analyse the various factors fuelling demand for Food- Away - From- Home (FAFH) in Ireland. The two largest components of this industry, the quick- service sector (fast food and takeaway) and the full- service sector (hotel and restaurant meals), are analysed using the most recently available Household Budget Survey data for Ireland. The results from a Box- Cox double hurdle model indicate that different variables affect expenditure in the different sectors in different ways. Income has a greater effect on full- service expenditure than on quick- service. Similarly households that are healthconscious indicate a greater preference for full- service meals while households with higher time values indicate a greater preference for...

A Dual Response Choice Experiments (DRCE) design to assess rabbit meat preference in Catalonia: A Heteroescedatistic Extreme-Value Model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kallas,   Zein; Maria Gil,   Jose.
Our paper analyzes consumer preferences toward fresh rabbit meat and alternative marketing formats for rabbit meat. The empirical analysis uses consumer-level questionnaires to elicit information regarding consumer attitudes toward rabbit meat in Catalonia (Spain). We use the Dual Response Choice Experiment (DRCE) design which allows for analyzing forced and unforced options in choice experiments using the same sample. The Heteroscedastic Extreme- Value (HEV) model is used due to its relaxation of the restrictive assumption made in the Multinomial Logit Model regarding the identically distributed error term across alternatives. Our results demonstrate a higher preference for rabbit meat from “Catalan” origin followed by higher quality certification...

A dual-frequency approach for retrieving sea surface wind speed from TOPEX altimetry
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chen, G; Chapron, Bertrand; Ezraty, Robert; Vandemark, D.
More than a dozen of wind speed (U) algorithms have been proposed during the past 2 decades, as a result of a continuing effort to improve altimeter wind measurement. The progress in terms of accuracy, however, is seen to be rather slow. The reported root mean square (RMS) error of prevailing algorithms varies mostly between 1.6 and 2.0 m/s for the dominant wind regime. As far as the TOPEX altimeter is concerned, three measured quantities, namely, the radar cross sections from Ku and C band (sigma(Ku) and sigma(C)), as well as the significant wave height (H-s), have been used in previous algorithm developments, resulting in a variety of single-, dual-, and three-parameter model functions. On the basis of the finding of a banded dependency of the...

A duality result between the minimal surface equation and the maximal surface equation
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: ALÍAS,LUIS J.; PALMER,BENNETT.
In this note we show how classical Bernstein's theorem on minimal surfaces in the Euclidean space can be seen as a consequence of Calabi-Bernstein's theorem on maximal surfaces in the Lorentz-Minkowski space (and viceversa). This follows from a simple but nice duality between solutions to their corresponding differential equations.

A Dual-mode model interpretation of CO2/CH4 permeability in polysulfone membranes at low pressures
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: BIONDO,LUCAS D.; DUARTE,JOCELEI; ZENI,MARA; GODINHO,MARCELO.
ABSTRACT An asymmetric membrane of polysulfone (PSf) was synthesized by phase inversion method. Permeation experiments were carried out between 2 to 5 bar pressure, and at temperatures 20 to 45°C. The dense-selective layer of PSf membrane presents regular thickness (about 5 µm), and was not possible to observe the formation of macrovoids in porous layer. The CO2 permeability through membrane was 18.8 Barrer at 35°C and 2 bar pressure, and this relationship between the pressure and the CO2 permeability was described adequately by Dual-mode model. The absence of CH4 permeability at 2 and 3 bar pressure, qualifies the PSf membrane for gases separation with high selectivity in this range.

A ‘during-infection’ spray strategy using sulphur compounds, copper, silicon and a new formulation of potassium bicarbonate for primary scab control in organic apple production.
Provedor de dados: Organic Eprints
Autores: Jamar, Laurent; Lefrancq, Bruno; Fassotte, Christianne; Lateur, Marc.
In a field experiment conducted over two growing seasons, the effectiveness and phytotoxicity of inorganic fungicides such as sulphur, lime sulphur, copper, silicon and Armicarb (a new formulation of potassium bicarbonate) was compared with water for the control of primary apple scab infections in Belgium on high, medium and low scab-susceptible cultivars (cvs. ‘Pinova’, ‘Pirouette’ and ‘Reinette des Capucins’, respectively). In order to drastically reduce the amount of fungicide applied in the orchard, two approaches were used: (i) a strategy involving spraying during the infection process, just before  conditions for infection had been fulfilled according to the RIMpro software warning system; and (ii) a tunnel sprayer machine for treatment applications....

A dynamic and mechanistic model of PCB bioaccumulation in the European hake (Merluccius merluccius)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bodiguel, Xavier; Maury, Olivier; Mellon-duval, Capucine; Roupsard, Francois; Le Guellec, Anne-marie; Loizeau, Veronique.
Bioaccumulation is difficult to document because responses differ among chemical compounds, with environmental conditions, and physiological processes characteristic of each species. We use a mechanistic model, based on the Dynamic Energy Budget (DEB) theory, to take into account this complexity and study factors impacting accumulation of organic pollutants in fish through ontogeny. The bioaccumulation model proposed is a comprehensive approach that relates evolution of hake PCB contamination to physiological information about the fish, such as diet, metabolism, reserve and reproduction status. The species studied is the European hake (Merluccius merluccius, L. 1758). The model is applied to study the total concentration and the lipid normalised...

A Dynamic Decision Support System for Farm Water Management in Surface Irrigation: Model Development and Application
Provedor de dados: Chilean Journal of Agricultural Research
Autores: Flores,Carlos I.; Holzapfel,Eduardo A.; Lagos,Octavio.
An online dynamic decision support system (DDSS) was developed, to support the farm water management in surface irrigation. The online DDSS was based on the formulation and integration of three components: a dynamic-relational data base, an administrator model, and a graphical user interface. The DDSS allows routines of actualization, edition and addition of online data, providing information in real time. The online DDSS was applied in an orange orchard (Citrus sinensis L. Osbeck) cv. Valencia Late under furrow irrigation. The results pointed out that the time irrigation cutoff was the main significant management factor, to decrease the hazard of leaching, superficial runoff and percolation. Applying the results obtained with the DDSS, furrow irrigation...

A Dynamic Energy Budget (DEB) Model for the Keystone Predator Pisaster ochraceus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Monaco, Cristian; Wethey, David S.; Helmuth, Brian.
We present a Dynamic Energy Budget (DEB) model for the quintessential keystone predator, the rocky-intertidal sea star Pisaster ochraceus. Based on first principles, DEB theory is used to illuminate underlying physiological processes (maintenance, growth, development, and reproduction), thus providing a framework to predict individual-level responses to environmental change. We parameterized the model for P. ochraceus using both data from the literature and experiments conducted specifically for the DEB framework. We devoted special attention to the model's capacity to (1) describe growth trajectories at different life-stages, including pelagic larval and post-metamorphic phases, (2) simulate shrinkage when prey availability is insufficient to meet...

A dynamic model for generating small-scale heterogeneities in ocean floor basalts
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bideau, Daniel; Hekinian, Roger.
Small-scale distribution of basaltic compositions along the mid-ocean ridge crests suggests that the magmatic processes are sensitive to spatial and temporal fluctuations related to proximity of ridge hot spots, changes in spreading rate, thermal boundary effects associated with ridge offsets, off-axis volcanoes and ridge propagators, and variations in magma supply through time. A detailed sampling of the East Pacific Rise (EPR) axis, near 13 degrees N, revealed that complex basalt compositional variations unrelated to morphology and structure occur both on the ridge axis and on nearby off-axis seamounts. This small-scale heterogeneity is attributed to successive magmatic cycles separated by periods of quiescence (amagmatic phases) where each cycle...

A obesidade atingiu proporções alarmantes em muitas partes do mundo e é um fardo para os sistemas de saúde tanto nos países desenvolvidos como nos países em desenvolvimento. Modificações no estilo de vida, como redução na atividade física e mudanças na dieta podem levar ao sobrepeso e à obesidade, que afetam quase 50% da população adulta e quase 30% da população infantil. Por essas razões, a Organização Mundial da Saúde considera a obesidade uma epidemia global e (KRISHNA et al., 2017; WHO, 2017), da mesma forma, a obesidade em cães está cada vez mais presente na prática clínica, sendo relacionada ao hábito de vida dos proprietários, que promovem o sedentarismo e fornecem ração ad libitum aos animais.

A Eficiência das Explorações Leiteiras Micaelenses (Açores)
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Almeida,Bruno Aires da Silva; Silva,Emiliana Leonilde Dinis Gil Soares da.
A discussão no âmbito da Política Agrícola Comum marca a atualidade açoriana. Um cenário possível é o decréscimo de apoios, subsídios à quota leiteira, aos produtores açorianos. Para compensar esta quebra de rendimento urge que os produtores leiteiros melhorem a eficiências das suas empresas agrícolas. Este trabalho tem como objetivo conhecer os valores de eficiência e estimar o número de explorações eficientes em S. Miguel, ilha que contribui com 75% da produção regional. A produção de leite dos Açores representa 30% da portuguesa. Neste trabalho utilizaram-se 91 explorações micaelenses. Estimam-se a eficiência usando o Deap. Utilizam-se dois modelos de eficiência não paramétrica alternativos: considerando, ou não, os subsídios como output. No Modelo I...

Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Ferrari,Magela Cavalleri; Braga,Marcelo José.
Resumo: O objetivo deste trabalho foi analisar a eficiência técnica dos produtores de leite no Uruguai, com base nos dados do Censo Geral Agropecuário, correspondente ao exercício produtivo 2010/2011. Empregou-se a abordagem da análise de fronteiras estocásticas, obtendo-se a medida da eficiência técnica média, assim como de cada estabelecimento. Os resultados mostraram que os produtores leiteiros do Uruguai operam, em média, aos 79,9% da sua capacidade, o que mostra que muitos deles poderiam ainda melhorar seus rendimentos com a tecnologia disponível. Além disso, os resultados mostram que a assistência técnica e a utilização de silos reduzem possíveis ineficiências.

Autores: EMBRAPA ARROZ E FEIJÃO.
O arroz, muito mais que simples comida, é um alimento de singular importância nutritiva e cultura. Um dos alimentos mais antigos de que se tem notícia, o arroz é também o que representa o maior potencial para combater a fome do mundo, já que é considerado um dos mais bem balanceados nutricionalmente. O arroz é responsável por 18% das calorias da dieta básica dos brasileiros. Considerando crianças na faixa etária de 1 a 5 anos, se estas comerem 100g de arroz cozido (4 colheres de sopa), elas já supriram 14% das necessidades diárias em proteínas, 6% de cálcio, 2 a 5% de ferro e 8 a 12% de zinco. O arroz não "engorda"! É um alimento rico em nutrientes, fibras e vitaminas, além de fornecer energia.

A erosividade das chuvas em Fortaleza (CE): II - correlação com o coeficiente de chuva e atualização do fator R no período de 1962 a 2000
Provedor de dados: Revista Brasileira de Ciência do Solo
Autores: Silva,J. R. C.; Dias,A. S.
A correlação entre o índice de erosividade EI30 e o coeficiente de chuva (Rc) no período de 1962 a 1981, em Fortaleza (CE), foi avaliada com o objetivo não só de analisar a viabilidade de utilização do Rc na atualização dos valores da erosividade no período de 1982 a 2000 nesse município, mas também de identificar uma equação que pudesse ser empregada para estimar a erosividade em outras localidades da zona litorânea do estado do Ceará onde não existem diagramas de pluviógrafos. Um alto coeficiente de correlação (r = 0,99**) foi encontrado entre os valores mensais do índice EI30 e o Rc. O melhor ajuste na regressão entre essas variáveis foi encontrado na equação EI30 = 73,989Rc0,7387. O emprego dessa equação permitiu atualizar o fator R em Fortaleza no...

A Estimação das importações brasileiras de leite, 1991 a 2003
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Santos,Dione Fraga dos; Barros,Geraldo Sant'Ana de Camargo.
Com o intuito de avaliar o efeito das importações de lácteos sobre algumas variáveis macroeconômicas: quantidade importada, preço de importação, preço interno, PIB (Produto Interno Bruto) real e taxa de câmbio real foi especificado um modelo econométrico para a demanda de importação para o período de janeiro de 1991 a dezembro de 2003. A metodologia empregada para medir os impactos das importações de leite nas variáveis macroeconômicas foi a de séries temporais. Incorporou-se uma análise gráfica a partir do diagrama back to back analisado por Barros (2003). E, ainda, utilizou-se a equação de excesso de demanda para definir a demanda por importação de leite.

A estimação do efeito residual de fertilizantes por meio da Lei de Mitscherlich
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Gomes,Frederico Pimentel.
This paper deals with the estimation of the residual effect of fertilizers through the use of Mitscherlich's law. The formulas and reasonings now presented are a further development of those introduced previously by PIMENTEL GOMES (2). The new formulas allow the estimation of the residual effect h in cases where the experiments are carried out in the same plots for two or three subsequent years (or crops). In an experiment analysed as an example, the residual effect of calcium hydroxide was estimated to be h = 0.423, that is, about 42%, so that one should advise the use of frequent application of small amounts of lime instead of heavy quantities used at long intervals.

The Vibrio splendidus clade has previously been associated with epidemic outbreaks of various aquatic animals, as in the case of the cupped oyster, Crassostrea gigas. To investigate whether involved strains could present a clonal origin and to identify possible alternative background carriage animals or zooplankton, a large epidemiological survey was conducted on isolates of the splendidus clade. For this purpose, Vibrio strains were isolated from various samples including oysters, mussels, sediments, zooplankton, and sea water on the basis of a North/South gradient of the European sea water zone (Ireland, The Netherlands, France, Italy, and Spain). A total of 435 isolates were successfully associated to the V. splendidus clade using real time polymerase...

A evaluation and interpretation of czcs-derived patterns on the adriatic shelf
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sturm, B; Kuzmic, M; Orlic, M.
The aim of the present paper is to investigate further the previously observed dichotomy in the Adriatic waters influenced by the Po river. To that end, an existing algorithm for pigment concentration retrieval has been improved and applied to the reprocessing of selected summer 1981 and winter 1981/1982 images of the Adriatic Sea. The sensitivity loss correction procedure has been included in the retrieval algorithm and rendered coherent with the atmospheric correction model. The model was also updated to allow for multiple Rayleigh scattering, and site-specific calibrated for case 2 waters of the Northern Adriatic. Our analysis of the images reinforces the previous finding (Clement et al., 1987) that two types of CZCS-derived patterns can be observed on...

Os equinos estabeleceram desde a antiguidade uma relação muito próxima ao homem, assumindo importância fundamental no desenvolvimento dos povos em todo o planeta. Embora tenham grande importância nas atividades esportivas e possam ser considerados animais de companhia, nas regiões metropolitanas das grandes cidades, equinos de tração são frequentemente utilizados como principal fonte de renda ou como forma de complementação desta para muitas famílias, realizando o transporte de entulhos, lixos recicláveis e móveis, entre outros. O grau de exclusão social pode ser representado por zonas homogêneas, conforme indicadores socioeconômicos e ambientais.

Introdução: já se sabe que a maternidade torna as mães mais agressivas que seus limiares de dor parecem alcançar níveis muito altos, já podem se submeter a frio, calor e fome intensos desde que seus filhos nada sofram. Dessa maneira supõe-se que a mulher/fêmea tenha um imput para ser maternal, particularmente quando há a presença do filho/prole e que exista um mecanismo analgésico endógeno ativado quando a fêmea encontra-se nessa situação. O surgimento e a manutenção do Comportamento Maternal são controlados pela interação de fatores ambientais, bioquímicos, hormonais e neurais. Os opióides estão intimamente ligados ao processo modulatório nociceptivo e quando ativados atuam por meio de receptores de subunidades mu, kappa e delta distribuídos pelo SNC,...

A experimentação do sisal: parte I - experiências de espaçamento
Provedor de dados: Bragantia
Autores: Medina,J. C.
Sisal (Agave sisalana Perrine) accounts for about one half of the world's production of hard fibers. In spite os its economic importance pratically no research work has been carried out on this plant. Very little is known about the agronomic problems of its cultivation, while the physiological and genetic problems are nearly unknown. This is perhaps due to the fact that A. sisalana is a perennial plant with a life cycle of 5-8 years and the carrying out of field research work requires a great deal of time and is very expensive. This paper, the first of a series to be published on the agronomic problems of sisal cultivation, presents the data obtained from field trials on distance of planting and its relation to weight and number of leaves produced.

A exploração da fauna silvestre no Brasil: Jacarés, sistemas e recursos humanos
Provedor de dados: Biota Neotropica
Autores: Verdade,Luciano M.
A conservação da vida silvestre normalmente necessita de estudos caso a caso porque a população - e não a espécie - deve ser na maioria das vezes a unidade do manejo. No Brasil, a falta de uma categoria profissional específica, como a dos wildlife biologists norte-americanos, dificulta a implantação de programas de conservação e manejo de vida silvestre. O preconceito contra o uso da fauna como recurso natural renovável, o abuso da criação em cativeiro e a noção de que o país não é capaz de implantar com sucesso um programa de fiscalização eficaz impedem a implantação de sistemas biologicamente sustentáveis, economicamente viáveis e socialmente justificáveis de uso da fauna silvestre. Isto só poderá mudar através da formação adequada de recursos humanos,...

Introdução: A droga de rua comercializada como crack, é constituída principalmente por cocaína (alcaloide tropânico com notável ação neuroestimulante) na sua forma de base livre, e atualmente vem se destacando como um problema social e de saúde pública, uma vez que a dependência química por esta forma de cocaína se dá com maior facilidade devido a seu alto potencial de abuso e baixo custo [1]. Apesar de existirem diversos estudos em modelos animais com outras formas de cocaína, raros são os relatos científicos que investigaram o efeito da fumaça do crack em roedores, devido à dificuldade de ser realizada a exposição à droga pela via pulmonar. Assim, o presente foi delineado para avaliar as possíveis alterações comportamentais em campo aberto e em labirinto...

A recreational fishery that use ghost-shrimp as bait was evaluated along 11 km of a sandy beach of Paraná State. The beach was divided in five sectors and samples were obtained along a transect extended on the middle of each sector, after and before months of major extractive activity. The highest densities were found in beaches with well select very fine sands and gentle slope. The density decreased only at the sector that presented greater extractive activity. In this sector, the smallest mean modal size was detected too. The total standing stock of the whole area was 2,486,250 individuals before summer's months, with a mean density of de 4.48 ind.m-2. Annual fishing effort represented nearly 10 % of total standing stock.

The solution of the problem whether the ultrabasic inclusions in lavas are accumulation products of early crystallized minerals of the lavas in which they occur, or fragments of the earth’s peridotite shell carried to the surface by the eruptive force of the lavas, largely depends on the answer to the question whether these inclusions are tectonites or not. The structure of the specimens from Auvergne (France), which formed the main subject of this study, has been proved conclusively to be of a tectonic nature, from the macroscopically visible intersecting slip planes which are definitely younger than the banding of the specimen, as well as from microscopic evidence that suggests that both the olivine and enstatite crystals are concentrated in the...

Based on the findings of this study, the following actions are proposed for consideration by the Government of Kenya: 1. Raise public investment in maize seed breeding and agronomic research to make it possible for improvements in smallholder crop productivity. Based on research evaluating the returns to alternative investments in agriculture, public expenditures in maize seed breeding and agronomy may constitute the single most important investment to promote broad-based productivity growth and poverty reduction in Kenya. 2. Explore options for improving public and private extension programs to enable farmers to adopt improved farm technologies generated from point 1. 3. Examine options for bringing more land in Kenya under potential cultivation by...

Previous studies analyzing the U.S. food industry have used national data and/or have focused on a particular sector of the industry.  However, regional differences in resource endowments, income opportunities and population distribution imply that the impact of changing economic environment will not be the same for all regions.  A farm to retail multiproduct sectoral model for the Northeast food industry is developed and estimated.  This regional approach is used to analyze the effects of changes in exogenous variables on the Northeast region's food production and consumption.  Empirical results are presented in terms of intrasectoral flexibilities and elasticities. Selected results from other regions are also presented and compared with the Northeast...

A FARM-LEVEL ANALYSIS OF SOIL LOSS CONTROL: MODELING THE PROBABILISTIC NATURE OF ANNUAL SOIL LOSS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McSweeny,   William T.
The Conservation Compliance provision of the Food Security Act of 1985 requires all farmers who farmed highly erodible land prior to the passage of the Act to have a locally approved conservation plan fully implemented by 1995 or lose eligibility for numerous farm programs.  Soil loss estimates of various crop, tillage practices, and conservation practices, however, are stochastic in nature.  A farm planning model is suggested that allows for stochastic soil loss estimates.  The model is compared to other models used in farm level soil conservation studies.  The model shows promise as a more acceptable tool in that the farm plans are more likely to be acceptable to the farmer.

Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Ocarino,N.M.; Serakides,R.; Nunes,V.A.
The effect of the estrogenic phase in the bone and in the mineral metabolism was studied in Wistar adult female rats kept under euthyroidism or hyperthyroidism for 60 days. The rats were divided, according to the stage of the estrous cycle, into four groups: 1) euthyroid (proestrus-estrus), 2) euthyroid (metaestrus-diestrus), 3) hyperthyroid (proestrus-estrus), and 4) hyperthyroid (metaestrus-diestrus). After 60 days the blood plasma was collected and the concentrations of free T4, estradiol, progesterone, calcium, phosphorus, and of alkaline phosphatase were determined. The bones (femur and tibia) were analysed microscopically. Despite of the functional state of the thyroid, the levels of estrogen were significantly higher in the proestrus-estrus. The...

A feeding association between Wilson's Storm-petrels Oceanites oceanicus (Kuhl, 1820) and Rough-toothed Dolphins Steno bredanensis (G. Cuvier in Lesson, 1828)
Provedor de dados: Biota Neotropica
Autores: Olmos,Fábio; Rotenberg,Elsie; Muscat,Edelcio.
On 06 October 2012 a pod of Rough-toothed Dolphins Steno bredanensis (Delphinidae) was observed catching and tearing apart several Castin Leatherjacks Oligoplites saliens (Carangidae) near Montão de Trigo Island, northern coast of São Paulo, Brazil. The resulting floating masses of viscera attracted a feeding aggregation of 120-150 Wilson's Storm-petrels Oceanites oceanicus (Hydrobatidae), a transequatorial migrant passing through the area during October. This interspecific association has not been recorded before, although it could be expected given that S. bredanensis feeds on large fish and O. oceanicus is a known scavenger of kills made by cetaceans such as Killer Whales.

A Kárpát-medence páratlan természeti kincseit számos veszély fenyegeti. E veszély elhárítására adhat megoldást a fenntartható fejlődés, melynek ugyan az elmúlt négy évtizedben széles körű szakirodalma jött létre, de világszerte gyengék a gyakorlati eredményei. A jelen tanulmány a gyakorlati megvalósítás, a fenntarthatóság felé való átmenet magyar útját vizsgálja a következő feltételek megvalósításával: 1. Illeszkedés egy hosszabb távú nemzetstratégiai tervhez az átmenet alap-feltételeként. 2. A társadalom fenntarthatóság iránti igényének felkeltése.  3. A magyar gazdaság szuverenitását több, egymással is összefüggő függőségi helyzet gyengíti.

1 - The present paper deals with the results of studies on pollen fertility, number of seeds per fruit and frequency of polyembryony in Citrus. 2 - The pollen may be divided into four groups of which the first consists of the living and functional grains, colouring deeply with carmín acetic, germinating in sugar solutions fairly well. The remainny three types : half filled grains, empty grains, and small deformed grains are all inviable. 3 - The grains are generally spherical, 15 to 40ix in diameter. The smallest grains were found in Citrus hystrix and Citrus mitis (fig. 3 and 4), while citron and the grape-fruits have the largest grains (fig. 1, 2 and 5). 4 - Size and form are reasonably constant, except the hybrid "Citran-gequat", "limão galego" without...

A field impression of the lichen and bryophyte zonation on Mount Kinabalu
Provedor de dados: Naturalis Digital Academic Repository
Autores: Sipman, H.J.M.; Tan, B.C.
Vegetation descriptions of Mount Kinabalu (4101 m), the highest mountain in tropical Asia between the Himalayas and New Guinea, have resulted in different, conflicting zonations. Some stress more on floristic affinities, others more on physiognomy. A lowland zone reaching to about 1000 m is usually distinguished. The next 2000 m comprising the mountain forests are treated in many different ways. A summit zone (above 3800 m) is recognized rather often (cf. Stapf, 1895; Gibbs, 1914; Meijer, 1963; Van Steenis, 1964; Menzel, 1988). In our opinion the most convincing is the zonation proposed by Van Steenis, who stressed the floristic composition. This comprises three zones: 1. the foothill zone below 1000 m; 2. the montane zone from 1000 to 2500 m; 3. the...

A field trial on the effects of pure sodium propionate and a combination with herbal extracts on short term development of subclinical ketosis
Provedor de dados: Organic Eprints
Autores: Dorn, Katharina; Leiber, Florian; Sundrum, Albert; Holinger, Mirjam; Mayer, Philipp; Walkenhorst, Michael.
While glucogenic substances in ketosis prevention are commonly used, there is a lack of clinical studies about the effectiveness of ketosis therapy in particular by means of sodium propionate and herbal extracts. Fresh cows between 5 and 50 days in milk of 25 Swiss and German dairy farms were tested weekly for ketone bodies in blood. From 283 cows, 121 (42.8%) exceeded the threshold of 1.0 mmol/l blood-β-hydroxybutyrate (BBHB). Thereof 84 cows were randomly assigned to three treatments on each farm. Treatment SP-H was composed of sodium propionate (120 g per application) and an aqueous extract of seven herbs (13.5 g drug equivalent per application), treatment SP comprised pure sodium propionate (120 g per application) and treatment PL was a placebo.

A financial analysis of the impact of sheep on the risks and returns associated with mixed enterprise dryland farming in south-eastern Australia: Part II
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hutchings,   Timothy R.
This paper extends the long-term cash-flow simulations reported in Part I (Hutchings 2009) to include a range of seasonal scenarios at four representative dryland sites in south-eastern Australia. The effect of varying the proportion of sheep and cropping in the enterprise mix at each site on cash surpluses is discussed. The analysis shows that, for most sites, the cropping enterprises require better than average seasons, prices and water-use efficiencies to generate a positive cash flow and are subject to substantial variability and risk of loss. In contrast, the sheep enterprises show small but stable cash flows in all but extreme drought conditions. This paper emphasises the need to include site-specific, long-term variability and whole-farm costs in...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parsons,   Robert L.; Hanson,   Gregory D.; Musser,   Wesley N.; Freund,   Roland; Power,   Lehan.
A financial training program designed by Cooperative Extension specialists was provided to over 2,000 USDA/FSA borrowers from the Northeast during the period 1994-1999. Key to the success of the workshops was an in-depth, user friendly curriculum that evolved over time, eventually replacing satellite-feed instruction with pre-taped videos. Cluster analysis classified nearly 70% of workshop participants as "Low Finance Priority" or "Low Finance Knowledge." Farmers in these clusters received a relatively greater educational benefit from the program than those not in these clusters. Impact analysis indicated that perceived annual gain in farm net worth from application of workshop tools ranged from approximately $5,000 to $10,000. The training addressed the...

Provedor de dados: Acta Amazonica
Autores: Gomes,Andreza Lourdes; Vieira,José Luiz Fernandes; Pinheiro,Maria da Conceição Nascimento; Marceliano,Maria Luiza Videira.
We evaluated in this study the total mercury concentration in feathers of Ardea albus collected in a colony located in the city of Belem-PA, Brazil in a prospective trial for its use as bioindicators of mercury burden in Amazonia ecosystems. An Atomic absorption spectrophotometry with gold amalgamation was used for the metal determination. The total mercury average concentration in body feathers was 2.2 ± 1.5 µg.g-1 and 1.3 ± 0.9 µg.g-1 in wing feathers. No correlation was observed between total mercury concentration and the length of body or wing feathers. Total mercury concentration was above 5 µg.g-1 dry weight in only one body feather sample.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lallias, Delphine; Beaumont, A.r.; Haley, C.s.; Boudry, Pierre; Heurtebise, Serge; Lapegue, Sylvie.
This study presents the first genetic linkage map for the European flat oyster Ostrea edulis. AFLP and 20 microsatellite markers were genotyped in a three-generation pedigree comprised of 2 grand-parents, 2 parents and 92 progeny. Chi-square goodness of fit tests revealed high segregation distortion, which was significant for 32.8% of markers. Sixteen microsatellites and 235 AFLPs (170 AFLPs type 1:1 and 65 AFLPs type 3:1) were used to build sex-specific linkage maps using CriMap software. The first parental map (P1) consisted of 104 markers grouped in nine linkage groups, spanning 471.2 cM with an average spacing of 4.86 cM. The second parental map (P2) consisted of 117 markers grouped in ten linkage groups (which equals the haploid chromosome number),...

A first genetic linkage map of the European flat oyster, Ostrea edulis : towards the identification of Bonamia resistance QTLs
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lallias, Delphine; Lapegue, Sylvie; Haley, Chris; Heurtebise, Serge; Boudry, Pierre; Beaumont, Andy.
The flat oyster Ostrea edulis is an endemic European oyster species, found on both Atlantic and Mediterranean coasts. Its aquacultural production has dramatically decreased due to two successive diseases caused by the intracellular parasites Marteilia refringens and Bonamia ostreae. Since 1985, Ifremer has undertaken a breeding program to produce oyster families which are tolerant to Bonamia. In this context, the next step is to identify QTLs for resistance to this parasite. A genetic map is therefore being established as a basis for QTL work. The reference family is an F2 family produced by single pair mating of two oysters from the same F1 family. The F1 family was itself produced from a bi-parental cross between a wild oyster and an individual from the...

A First Look at Dissolved Ge Isotopes in Marine Sediments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Baronas, J. Jotautas; Hammond, Douglas E.; Rouxel, Olivier; Monteverde, Danielle R.
The removal of chemical species from seawater during the precipitation of authigenic minerals is difficult to constrain but may play a major role in the global biogeochemical cycles of some elements, including silicon (Si) and germanium (Ge). Here, we present Ge/Si, δ74Ge, and supporting chemical data of pore waters and core incubations at three continental margin sites in California and the Gulf of Mexico. We used these data to partition Ge release and uptake by the various allogenic (delivered via sedimentation) and authigenic (formed in situ) phases in these sediments. About half of the pore water Ge (δ74Gepw = 1.3–2.4‰) is supplied by biogenic silica dissolution (δ74Ge ~ 3‰), with the other half contributed by lithogenic particulates (δ74Ge ~ 0.6‰)....

A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Saraswat, R; Nigam, R; Weldeab, S; Mackensen, A; Naidu, Pd.
Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last similar to 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record the equatorial Indian Ocean SST was similar to 2.1 degrees C colder during the last glacial maximum as compared to present times. The data further shows that the surface equatorial Indian Ocean was comparatively warmer during isotopic stage 5e than at present (similar to 29.9 vs similar to 28.5 degrees C). Comparison of the equatorial Indian Ocean SST with the Antarctic delta D and Greenland delta(18)O records, shows that the major high-latitude cooling/warming events are also present in the equatorial Indian Ocean SST variation...

A recent focusing event involving the death of a moose in the Dome open-pit mine in the community of Timmins, in northern Ontario, Canada has triggered the opening of a policy window related to the governance of resource extraction by indigenous peoples. This event, combined with several other factors, including: (1) the high price of gold; (2) a mining company seeking to demonstrate corporate social responsibility to repair its international reputation with indigenous peoples by supporting an innovative, local Indigenous-led initiative; and (3) a new policy context, including Supreme Court of Canada decisions and provisions in the updated Ontario Mining Act, that require meaningful consultation with indigenous peoples has led to the emergence of a...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Madhupratap, M; Sawant, S; Gauns, M.
A thick bloom of the marine prymnesiophycean, Phaeocystis globosa was observed in the central Arabian Sea during the summer monsoon period (July-August, 1996). The cells were mostly in colonial form, embedded in gelatinous matrices. The cell diameter was approximately 7 mu m and showed a distinct double feature form. The intensity of the bloom was as high as 3750 x 10(6) cells m(-2) and the carbon content ranged between 33 and 550 mu g L(-1). Almost 90% of the phytoplankton population was composed of P. globosa in the bloom area. Other common forms were chain-forming diatoms like Rhizosolenia spp., Nitzschia spp. and Chaetoreros spp. The photosynthetic pigment chlorophyll a, however did not show any concomitant rise with the bloom intensity probably...

Seafloor long-term, multiparameter, single-frame observatories have been developed within the framework of European Commission and Italian projects since 1995. A fleet of five seafloor observatories, built-up starting from 1995 within the framework of an effective synergy among research institutes and industries, have carried out a series of long-term sea experiments. The observatories are able to operate from shallow waters to deep-sea, down to 4000 m w.d., and to simultaneously monitor a broad spectrum of geophysical and environmental processes, including seismicity, geomagnetic field variations, water temperature, pressure, salinity, chemistry, currents, and gas occurrence. Moreover, they can transmit data in (near)-real-time that can be integrated with...

A Flexible Inventory Model for MSW Recycling
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Louis,   Garrick; Shih,   Jhih-Shyang.
Most of the United States have laws mandating the recycling of municipal solid waste (MSW). In order to comply, municipalities recycle quotas of materials, without regard to fluctuating prices. An inventory system is proposed that allows municipalities to be sensitive to materials prices as they recycle in accordance with state mandates. A dynamic model is developed; it uses historical secondary material prices as exogenous inputs to minimize the net present value of MSW recycling system cost. The model provides a cost-effective method for municipalities to achieve their MSW recycling targets. The savings is approximately $1.43 per ton of MSW generated based on total MSW management costs of $13.5 per ton. The model also allows one to investigate the...

A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea
Provedor de dados: Genetics and Molecular Biology
Autores: Dornelas,Marcelo Carnier; Rodriguez,Adriana Pinheiro Martinelli.
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene has a large C-terminal region of high similarity to angiosperm FLO/LFY orthologs and shorter regions of local similarity. In contrast to angiosperms, conifers have two divergent genes resembling LFY. Gymnosperm FLO/LFY proteins constitute a separate clade, that can be divided into two divergent groups. Phylogenetic analysis of deduced protein sequences has shown that PcLFY belongs to the LFY-like clade....

A flow cytometric approach to study intracellular-free Ca2+ in Crassostrea gigas haemocytes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Aton, Emilie; Renault, Tristan; Gagnaire, Beatrice; Thomas Guyon, Hélène; Cognard, C; Imbert, N.
Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium.   Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Aminot, Alain; Kerouel, Roger; Birot, Dominique.
A version of the orthophthaldialdehyde-fluorescence ammonium determination for flow injection analysis (FIA) is presented here, with a view to its use for in situ, low-power consumption systems, Thus, the reaction temperature was limited to 30 degreesC and FIA was used in stop-Bow mode (3 min stop). The calibration is linear up to 50 mu mol l(-1), but concentrations up to 100 mu mol l(-1) can be measured. Repeatability is around 1% in the range of 0.5-4 mu mol l(-1) and the detection limit is about 0.03 mu mol l(-1) Over the salinity range of 5-35 (seawater practical salinity scale) the salt effect is almost negligible (within +/- 2%); and below salinity of 5 it increases to a maximum of -9% in fresh water compared to seawater.

While literature is relatively abundant on adult shellfish, ecophysiological studies at the larval stage are scarce because of both technical difficulties and inadequate methodology. A tool dedicated to provide basic information for larval ecophysiology was accordingly developed. Two steps were followed: first a flow-through method of Crassostrea gigas larval culture was perfected during a set of experiments in which rearing systems and larval density were assessed. Then a continuous hydrobiological data recorder was adapted with modifications to comply with our experimental aim. SILO (Système d'Instrumentation des Larves en flux Ouvert) allowed the successive acquisition of hydrobiological parameters in ten 150 l larval tanks in which larvae were reared...

This research reports the findings of focus group interviews which explored potato buying motives and preferences for russet, red skinned and round white potatoes among selected Northeastern consumers.  The results indicate that the group members perceived all russets as "Idaho" potatoes, associated the red potatoes with gourmet meals, and viewed the round whites as generic potatoes, unsuitable for company meals.  However, participants identified round whites as their personal favorite and as the kind they purchased most often.

A Gyöngyösi Kistérségben végzett felmérés tapasztalatai azt mutatták, hogy élénkült a kistérség földpiaca. A földbérleti díjak és árak egyaránt emelkedő tendenciát mutattak, szélsőséges ingadozások mellett. A vizsgált időszakban ér-tékesítettek termőföldet hektáronként 80 ezer forintért és 4,5 millió forintért is. Egyszerre van jelen a földtől való mindenáron való szabadulás és a vétel szándé-ka. A jövőre nézve a földár és a haszonbérleti díj növekedése várható, de ez az EU átlag alatt alakul hosszabb távon is. A föld birtoklása – helyzetétől függően – a jövőben kimagasló hozamot biztosíthat, és várhatóan meghaladja a lekötött bankbetétek hozamát, sőt esetenként extraprofit is elérhető.

A „Gazdálkodás” 2010. évi 2. számában vitacikkem jelent meg „A földbirtok-politikaválaszt igénylő kérdései” címen. Ezzel az volt a célom, hogy a témakörrel kapcsolatban felvessek kérdéseket, leírjak megállapításokat, és ezzel egy olyan vitát generáljak, ami fórumot ad a tudományos közélet szereplőinek a megszólalásra, a vélemények ütköztetésére, egymás nézeteinek jobb megértésére, a politika számára javaslatok megfogalmazására. A vitában az agrárgazdaságtan, üzemtan képviselői és mások kifejthették a véleményüket olyan fontos birtokpolitikai kérdésekkel kapcsolatban, mint a földtulajdon, a földhasználat, a földbérlet, a földpiac, a mezőgazdasági üzemszabályozás, a tagosítás, a föld öröklése, a külföldiek földhöz jutása, az állam szerepvállalása és ennek...

A földbirtok-politika választ igénylő kérdései
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kapronczai,   Istvan.
A kérdések széles területet ölelnek fel, ami folytatható a földvédelemmel, a kör-nyezetvédelemmel, a földadó kérdésével stb. A politikának – kompromisszumokkal és megegyezéssel – mielőbb lépnie kell, mert a rendezett birtokviszonyok növelik a földárat, élénkítik a termőföld iránti keresletet. Az emelkedő árak ugyanakkor bővítik a földkínálatot, végeredményben élénkül az egész földpiac. Ez a leghatékonyabb eszköz a termőfölddel kapcsolatos spekulációk visszaszorítására. Van-e azonban esély a megegyezésre? Politikai síkon aligha! Sőt az agrárközgazdász szakma is meglehetősen megosztott a birtok, a föld kérdésében, hisz körein¬ken belül is hatnak az érdekek, a megcsontosodott előítéletek. Mégis szükség van egy szakmai vitára, egy őszinte véleménycserére,...

A fossil gazelle (Gazelle schreuderae nov. spec.) from the Netherlands
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hooijer, D.A.
In 1944 Miss Dr. A. Schreuder sent me for identification a fossil horncore, which according to the accompanying letter came from a well-boring near Grubbenvorst (province of Limburg). It was found in a coarse sandy layer with gravel at a depth of 61.50 m below the surface; the topographic height of the latter is given as 24.53 m + N.A.P. (N.A.P. = sea-level at Amsterdam). Dr. J. F. Steenhuis, geologist to the Government Geological Foundation, informed me that deep borings for the water-supply of Central-Limburg have been made in the years 1918, 1919, and 1922 S. and S.E. of Grubbenvorst. Evidently we have to do with boring no. I of October 1918, which reached a depth of 83 m, the top being at 24.50 m + N.A.P. (Geological Foundation Index no. 695/4). The...

A Fractal Landscape Realizer for Generating Synthetic Maps
Provedor de dados: Ecology and Society
Autores: Hargrove, William; Oak Ridge National Laboratory; hnw@fire.esd.ornl.gov; Hoffman, Forrest M; Oak Ridge National Laboratory;; Schwartz, Paul M; ;.
A fractal landscape realizer has been developed that generates synthetic landscape maps to user specifications. The alternative landscape realizations are not identical to the actual maps after which they are patterned, but are similar statistically (i.e., the areas and fractal character of each category are replicated). A fractal or self-affine pattern generator is used to provide a spatial probability surface for each category in the synthetic map. The Fractal Realizer arbitrates contentions among categories in a way that makes it possible to preserve the fractal patterns of all the categories in the resulting synthetic landscape. Each synthetic landscape is one equally likely realization from among an infinite ensemble of possible fractal landscape...

A framework for assessing impacts of community-based enterprises on poverty reduction: a case study in northern Thailand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Terrakul,   Nuttamon; Villano,   Renato A.; Wood,   Fiona; Mounter,   Stuart W.
Poverty alleviation remains a challenge for Thailand’s socio-economic development. A key strategy of the Thai government to help meet this challenge at the ‘grass roots’ level has been the promotion of Community-Based Enterprises (CBEs). And national statistics and descriptive studies have shown that CBEs have led to both income improvement and employment creation. However, poverty is a multi-dimensional concept and also some groups are more adversely affected (such a women) than others. By investigating poverty from a number of different angles, this research aims to assess whether CBES are a genuine tool for poverty reduction at the individual household level. This paper provides an outline of the framework developed for assessing CBE impact on poverty...

Participatory research relies on stakeholder inputs to obtain its acclaimed benefits of improved social relevance, validity, and actionability of research outcomes. We focus here on participatory research in the context of natural resource management. Participants&amp;#8217; acceptance of participatory research processes is key to their implementation. Our first assumption is that this positive view and acceptance of participation in research processes is a public good for the whole participatory research community. We also assume that the diversity of participatory forms of research is rarely considered by potential participants when they make their decisions about whether or not to participate in a proposed process. We specifically address how to avoid...

Autores: Lyford,   Conrad P.; Ricks,   Donald J.; Peterson,   H. Christopher; Sterns,   James A.
As agricultural commodity industries strategically plan for their future, they need to consider the systemic and synergistic effects of such factors as changing government regulations, demand expansion or contraction, globalized markets, increased competitive pressures, and greater customer quality requirements. This article discusses a framework developed to help industries strategically plan within the context of these dynamic factors. This framework, based upon relevant theory and an accumulation of experiences with this type of strategic planning, provides one possible approach for addressing the strategic needs of an entire industry. In this way, a commodity industry as a whole can identify and address key industrywide strategic issues to maintain and...

A framework for evaluating management plans comprehensively
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Trenkel, Verena; Rochet, Marie-joelle; Rice, Jake C.
We present a framework for evaluating fisheries management plans comprehensively, both rebuilding plans and others. The framework includes a first rapid appraisal of the likelihood that the plan will result in management meeting its objectives, and guides subsequent quantitative analyses of potential weaknesses in the proposed plan. The framework includes four steps: (i) evaluating if a set of management objectives, if achieved, would result in a sustainable fishery, (ii) using qualitative analysis of a bio-economic model to evaluate whether the set of stock management tactics might be capable of achieving the specified fisheries objectives, (iii) using empirical criteria derived from the literature to evaluate if other management measures in the plan...

A framework for selecting a suite of indicators for fisheries management
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rice, Jake; Rochet, Marie-joelle.
We develop a framework for the objective selection of a suite of indicators for use in fisheries management. The framework encompasses eight steps, and provides guidance on pitfalls to be avoided at each step. Step I identifies user groups and their needs, featuring the setting of operational objectives, and Step 2 identifies a corresponding list of candidate indicators. Step 3 assigns weights to nine screening criteria for the candidate indicators: concreteness, theoretical basis, public awareness, cost, measurement, historic data, sensitivity, responsiveness, and specificity. Step 4 scores the indicators against the criteria, and Step 5 summarizes the results. Steps 3-5 offer technical aspects on which guidance is provided, including scoring standards...

A framework to quantify uncertainties of seafloor backscatter from swath mapping echosounders
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Malik, Mashkoor; Lurton, Xavier; Mayer, Larry.
Multibeam echosounders (MBES) have become a widely used acoustic remote sensing tool to map and study the seafloor, providing co-located bathymetry and seafloor backscatter. Although the uncertainty associated with MBES-derived bathymetric data has been studied extensively, the question of backscatter uncertainty has been addressed only minimally and hinders the quantitative use of MBES seafloor backscatter. This paper explores approaches to identifying uncertainty sources associated with MBES-derived backscatter measurements. The major sources of uncertainty are catalogued and the magnitudes of their relative contributions to the backscatter uncertainty budget are evaluated. These major uncertainty sources include seafloor insonified area (1–3 dB),...

Although cross-disciplinary research collaboration is necessary to achieve a better understanding of how human and natural systems are dynamically linked, it often turns out to be very difficult in practice. We outline a framing approach to cross-disciplinary research that focuses on the different perspectives that researchers from different backgrounds use to make sense of the issues they want to research jointly. Based on interviews, participants&amp;#8217; evaluations, and our own observations during meetings, we analyze three aspects of frame diversity in a large-scale research project. First, we identify dimensions of difference in the way project members frame the central concept of adaptive water management. Second, we analyze the challenges...

Autores: Nekhay,   Olexandr; Gay,   Stephan Hubertus; Fellmann,   Thomas.
The negotiations on a deep and comprehensive free trade agreement (FTA) between Ukraine and the EU are currently in process. Such a FTA can be expected to imply opportunities as well as challenges for agricultural markets. This paper provides a model-based quantitative assessment of the potential impacts of a FTA on agricultural commodity markets in the EU and Ukraine. For the quantitative analysis the dynamic, partial equilibrium model AGLINK-COSIMO has been adapted and applied. The modules for the EU and Ukraine have been extracted from the global model and prepared to run together. Thus, the focus is on the bilateral trade positions and not on the effect on other countries. The simulation of a FTA between the EU and Ukraine was done through the...

Fucans, a family of sulfated polysaccharides present in brown seaweed, have several biological activities. Their use as drugs would offer the advantage of no potential risk of contamination with viruses or particles such as prions. A fucan prepared from Spatoglossum schröederi was tested as a possible inhibitor of cell-matrix interactions using wild-type Chinese hamster ovary cells (CHO-K1) and the mutant type deficient in xylosyltransferase (CHO-745). The effect of this polymer on adhesion properties with specific extracellular matrix components was studied using several matrix proteins as substrates for cell attachment. Treatment with the polymer inhibited the adhesion of fibronectin to both CHO-K1 (2 x 10(5))()and CHO-745 (2 x 10(5) and 5 x 10(5))...

abstract Daptomycin (DPT) was the first lipopeptide antibiotic available for commercialization. It is active against gram-positive bacteria, including resistant strains. This work aimed to develop and validate a turbidimetric microbiologic assay to determine daptomycin in an injectable form. A 3x3 design was employed, at concentrations of 1, 2 and 4.0 µg/mL. The microorganism test used was Staphylococcus aureus ATCC 6538p, and Antibiotic Medium 3 was used as the culture medium. Method validation demonstrated that the bioassay was linear (r=0.9995), precise (RSD=2.58%), accurate (recovery 100.48± 2.11%), and robust. Degradation kinetics was also performed in an alkaline medium, indicating that daptomycin degradation follows first order kinetics under these...

Autores: Manfio,Maria Luisa; Agarrayua,Danielle Araújo; Machado,Jaison Carlosso; Schmidt,Cleber Alberto.
Ceftriaxone (CFTX) sodium is a third-generation, broad-spectrum cephalosporin that is resistant to beta-lactamases. An alternative bioassay for the assessment of the potency of this drug in pharmaceutical formulations has not been previously reported. Thus, this paper reports the development and full validation of a 3 x 3 agar diffusion bioassay using a cylinder-plate method to quantify CFTX sodium in pharmaceutical samples. The strain Staphylococcus aureus ATCC 6538P was used as the test microorganism, and the results of the proposed bioassay displayed high linearity, precision, accuracy, specificity and robustness. All potency results were statistically analyzed using an analysis of variance (ANOVA) and were found to be linear (r=0.99999) in the range of...

Autores: BALIEIRO, F. C.; DIAS, L. E.; FRANCO, A. A.; POLIDORO, J. C.
1. Introdução Os estudos com S na agricultura brasileira se intensificaram a partir da década de oitenta, quando o Cerrado passou a ser a nova fronteira agrícola nacional. Por possuir solos predominantemente oxídicos, com cargas positivas em condições naturais (pH abaixo do ponto de carga zero), observa-se que são solos com elevada capacidade de adsorção de fosfato e sulfato (FONTES et al., 1982; ALVAREZ VIEGAS, 1988; ALVAREZ VIEGAS, 2000; RIBEIRO JÚNIOR et al., 2001). Assim, vários autores relatam que a adição de formulações concentradas em macronutrientes primários (N-P2O5-K2O) e exportações consideráveis de nutrientes via colheita levam à deficiência induzida de S e, consequentemente a respostas positivas à adubação sulfatada a diversas culturas...

The objective of the present study was to assess esophageal motor function in 21 children (7.5 ± 2.9 years) with caustic strictures. Esophageal manometry was performed using a water-infusion system interfaced with a polygraph and displayed on a computer screen. The data were compared with those obtained from 9 healthy children. Radionuclide transit was determined by studying deglutition of a single bolus of 99mTc pertechnetate in 10 ml of water. Non-peristaltic low-amplitude and long-duration waves were the most common findings detected in patients with strictures longer than 20% of esophageal length (N = 11). Compared with the control group, these patients presented lower mean amplitude and longer mean duration of waves (24.4 ± 11.2 vs 97.9 ± 23.7 mmHg, P...

A kutatás célja az, hogy megállapítsuk, milyen habitussal rendelkeznek a gazdák, és melyikkel képesek eredményesen alkalmazkodni a piacgazdasághoz. A teljes munkaidőben dolgozó egyéni gazdákra az a jellemző, hogy nagyon szeretnek dolgozni, amit a szüleiktől örököltek. Valamennyien nagyon erős egyéniségek, ezért is építették ki a saját gazdasági autonómiájukat, amivel létrejött autonóm személyiségük is. A mezőgazdaságban az egyéni gazdák a gazdálkodás kialakításához a „készen talált” mintákat először is a háztájiból vették, továbbá a teljes kollektivizálás előtti családi gazdaságokból és csak harmadsorban a korábbi munkahelyi kapcsolatokból, tapasztalatokból.

Gas phase enthalpies of formation at 298.15 and 1 atm (&amp;#x394;~f~H~(g),298K~) were calculated using the atomization approach at the G4MP2 composite method level of theory for 86 polyaromatic hydrocarbons (PAHs) and other C~10~ through C~20~ unsaturated hydrocarbons. Where available, good agreement with prior experimental data and/or high level theoretical estimates was obtained. Linear regressions between semiempirical MNDO, MNDO-d, AM1, PM3, RM1, and PM6 estimated &amp;#x394;~f~H~(g),298K~ and the corresponding G4MP2 values were employed to obtain G4MP2 corrected semiempirical &amp;#x394;~f~H~(g),298K~ for a suite of 156 C~11~ through C~42~ unsaturated hydrocarbons and PAHs.

A GABONAPIACI KERESLET SZEREPLŐINEK ÁTALAKULÁSA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kemenyne Horvath,   Zsuzsanna.
A tanulmány bemutatja a hazai gabona keresletében bekövetkezett vertikális és horizontális átrendeződést és annak hatásait. A kérdőíves megkeresés és a mélyinterjúkból született válaszokat felhasználva, klaszteranalízis segítségével lehetővé vált a felvásárlói oldalon álló szereplők tipizálása, továbbá az áralku döntéseik modellezése. Megállapítható, hogy a gabonapiacon elsősorban a nagy kereskedelmi cégek és holdingok az árvezetők, ami méretükkel, tároló kapacitá-saikkal, logisztikai adottságaikkal és stratégiájukkal magyarázható. A feldolgo-zók (malom, takarmánykeverő, vetőmagos cégek), az integrátorok, kiskereskedők és egyéb cégek árelfogadók a gabonapiacon. Az intervenciós árszint a keresleti oldalon álló szereplők áralkuit, gabonapiaci stratégiáját...

A GAME THEORETIC ANALYSIS OF TURKISH ACCESSION TO A EUROPEAN CUSTOMS UNION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kennedy,   P. Lynn; Atici,   Cemal.
The entrance of additional countries into a European customs union, in this case Turkey, and its impact on agriculture are examined. Results from a trade simulation model are used as components of a Political Preference Function and utilized within a game theoretic framework to identify the optimal strategies for Turkey, the EU, and the U.S. Turkey's best interest, from an agricultural perspective, involves adoption of agreements made in the Uruguay round of GATT as a developing country rather than applying EU protection. Although free trade is not the optimal solution, simulations indicate that the solution does involve the reduction of agricultural protection levels.

A Game Theoretic Approach to Analyse Cooperation between Rural Households in Northern Nigeria
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gerichhausen,   M.; Berkhout,   Ezra D.; Hamers,   H.J.M; Manyong,   Victor M.
To improve the livelihood of the poor in Sub-Saharan Africa (SSA) much attention has been paid to the development of new agricultural technologies. We hypothesize that farmers can also improve their livelihood through cooperation. Partial cooperation, in which knowledge is shared or bargaining power improved, is relatively common in SSA, while cooperation where all resources are fully shared, which we address, has rarely been investigated. An important pre-requisite to establish such cooperation, is the need for a fair division rule for the gains of the cooperation. This paper combines linear programming and cooperative game theory to model the effects of cooperation of (individual) households on income and farm plans. Linear programming establishes...

A Gardener's Influence on Urban Soil Quality
Provedor de dados: Organic Eprints
Autores: Tresch, Simon; Moretti, Marco; Le Bayon, Renée-Claire; Mäder, Paul; Zanetta, Andrea; Frey, David; Fliessbach, Andreas.
Gardens are hot spots for urban biodiversity and provide habitats for many plant and animal species, both above- and below-ground. Furthermore, gardens provide a wide range of ecosystem services, including carbon (C) storage and nutrient cycling. Although the soil is the foundation of sustainable gardens providing those ecosystem services, very little is known about the consequences of garden management on soil quality. Here we present a comprehensive assessment of urban garden soil quality, including biotic and abiotic site characteristics combined with land-use history and garden management information in a multivariate evaluation. A set of 44 soil quality indicators was measured at 170 sites of 85 gardens in the city of Zurich, Switzerland, comprising...

A gasometric method to determine erythrocyte catalase activity
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Siqueira,A.J.S.; Remião,J.O.; Azevedo,A.M.P.; Azambuja,C.R.J.
We describe a new gasometric method to determine erythrocyte catalase activity by the measurement of the volume of oxygen produced as a result of hydrogen peroxide decomposition in a system where enzyme and substrate are separated in a special reaction test tube connected to a manometer and the reagents are mixed with a motor-driven stirrer. The position of the reagents in the test tube permits the continuous measurement of oxygen evolution from the time of mixing, without the need to stop the reaction by the addition of acid after each incubation time. The enzyme activity is reported as KHb, i.e., mg hydrogen peroxide decomposed per second per gram of hemoglobin (s-1 g Hb-1). The value obtained for catalase activity in 28 samples of hemolyzed human blood...

A gender performance indicator for irrigation:  Concepts, tools and applications
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: van Koppen,   Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

A General Conceptual Approach to Modeling the Livestock Sector: Application to the Japanese Swine-Pork Sector Model with Analysis of the "No Gate Price Policy Scenario"
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fabiosa,   Jacinto F.
This study develops a generic conceptual approach to modeling the livestock sector that provides better coverage of variables to ensure the consistency in the underlying biologics of the model and also provides consistent rules of specification. This approach is applied to modeling the swine-pork sector of Japan and then used to analyze the impact of removing Japan's gate price policy and variable levy for pork imports. The new approach departs significantly from existing models. For consistency in the biologics of the model both live animals and meat components of the sector are fully covered.  The structure clearly differentiates stock and flow variables and investment and production decisions. A standard rule of specification is established that only...

A general extrudate bulk density model for both twin-screw and single-screw extruder extrusion cooking processes
Provedor de dados: Organic Eprints
Autores: Cheng, Hongyuan; Friis, Alan; Høeg Hansen, Jonas; Tolderlund Rasmussen, Hanne.
Effects of extrusion parameters and raw materials on extrudate expansion are respectively investigated in a twin-screw extruder and a single-screw extruder extrusion cooking experiments for fish feed, wheat, and oat &amp; wheat mixture processing. A new phenomenological model is proposed to correlated extrudate bulk density, extrusion parameters and raw material changes based on the experimental results. The average absolute deviation (AAD) of the correlation is 2.2% for fish feed extrusion in the twin-screw extrusion process. For the single-screw extrusion process, the correlation AAD is respectively 3.03%, 5.14% for wheat and oat &amp; wheat mixture extrusion; and the correlation AAD is 6.6% for raw material change effects.

A GENERAL FRAMEWORK FOR GRAIN BLENDING AND SEGREGATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sivaraman,   Eswar; Lyford,   Conrad P.; Brorsen,   B. Wade.
The Hennessy and Wahl model of optimal grain blending and segregation (GBS) is extended to the case where it is not possible to separate components within a load. Analytical solutions are not available when segregation is the optimal strategy, and so solutions are obtained with nonlinear optimization. The model is then used to determine the optimal sorting of hard red winter wheat by protein content.  Most of the benefits from sorting can be obtained with only two bins.

A generalized nonlinear tempeature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang &amp;amp; A. R. Ferguson)
Provedor de dados: Ciência Rural
Autores: Streck,Nereu Augusto.
Temperature is a major factor that affects metabolic processes in living organisms. Thermal time has been widely used to account for the effects of temperature on crop growth and development. However, the thermal time approach has been criticized because it assumes a linear relationship between the rate of crop growth or development and temperature. The response of the rate of crop growth and development to temperature is nonlinear. The objective of this study was to develop a generalized nonlinear temperature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang &amp;amp; A. R. Ferguson). The nonlinear function has three coefficients (the cardinal temperatures), which were 0ºC, 25ºC, and...

A generic approach for representing complex structures in biological models
Provedor de dados: Nature Precedings
Autores: Robert I. Muetzelfeldt.
Increasingly, the biological modelling community is looking for ways of handling complex and possibly dynamic structures in their models.   On the one hand, the pathway-modelling groups (SBML and CellML) seek to move up levels of organisation, while on the other hand the &amp;#x22;Virtual X&amp;#x22; communities (where X is some organism or organ) need to represent the organisational structure within their object of study.   To date, various approaches have been proposed, such as  the SBML Level 3 &amp;#x27;comp&amp;#x27;, &amp;#x27;spatial&amp;#x27;, &amp;#x27;array&amp;#x27; and &amp;#x27;dyn&amp;#x27; extension packages, and domain-specific elements in languages such as NeuroML, but there is no generic approach intended to be adopted by the various...

A Generic, Computer-assisted Method for Rapid Vegetation Classification and Survey: Tropical and Temperate Case Studies
Provedor de dados: Ecology and Society
Autores: Gillison, Andrew N; Center for Biodiversity Management; andy.gillison@austarnet.com.au.
Standard methods of vegetation classification and survey tend to be either too broad for management purposes or too reliant on local species to support inter-regional comparisons. A new approach to this problem uses species-independent plant functional types with a wide spectrum of environmental sensitivity. By means of a rule set, plant functional types can be constructed according to specific combinations from within a generic set of 35 adaptive, morphological plant functional attributes. Each combination assumes that a vascular plant individual can be described as a "coherent" functional unit. When used together with vegetation structure, plant functional types facilitate rapid vegetation assessment that complements species-based data and makes possible...

A genetic comparison of Atlantic and Mediterranean populations of a saltmarsh beetle

Autores: Desender, K.; Serrano, J.
Enzyme and dispersal polymorphism in the saltmarsh carabid beetle &lt;i&gt;Pogonus chalceus&lt;/i&gt; Marsham were compared between 30 Atlantic and nine Mediterranean European populations. Allozyme results showed that Mediterranean beetles (France, Spain) are genetically distinct from Atlantic populations. All Mediterranean beetles screened showed complete fixation at one locus (IDH1), which in Atlantic populations nearly always varied, whereas some unique Mediterranean alleles were observed for another locus (MPI). Genetic differentiation (allozymes) between Mediterranean populations, although highly significant, appeared to be much lower (F&lt;sub&gt;st&lt;/sub&gt; = 0.098) than between Atlantic populations (F&lt;sub&gt;st&lt;/sub&gt; = 0.178).

A genomic analysis of disease-resistance genes encoding nucleotide binding sites in Sorghum bicolor
Provedor de dados: Genetics and Molecular Biology
Autores: Cheng,Xiao; Jiang,Haiyang; Zhao,Yang; Qian,Yexiong; Zhu,Suwen; Cheng,Beijiu.
A large set of candidate nucleotide-binding site (NBS)-encoding genes related to disease resistance was identified in the sorghum (Sorghum bicolor) genome. These resistance (R) genes were characterized based on their structural diversity, physical chromosomal location and phylogenetic relationships. Based on their N-terminal motifs and leucine-rich repeats (LRR), 50 non-regular NBS genes and 224 regular NBS genes were identified in 274 candidate NBS genes. The regular NBS genes were classified into ten types: CNL, CN, CNLX, CNX, CNXL, CXN, NX, N, NL and NLX. The vast majority (97%) of NBS genes occurred in gene clusters, indicating extensive gene duplication in the evolution of S. bicolor NBS genes. Analysis of the S. bicolor NBS phylogenetic tree revealed...

A genomic approach to elucidating grass flower development
Provedor de dados: Genetics and Molecular Biology
Autores: Dornelas,Marcelo C.; Rodriguez,Adriana P.M.
In sugarcane (Saccharum sp) as with other species of grass, at a certain moment of its life cycle the vegetative meristem is converted into an inflorescence meristem which has at least two distinct inflorescence branching steps before the spikelet meristem terminates in the production of a flower (floret). In model dicotyledonous species such successive conversions of meristem identities and the concentric arrangement of floral organs in specific whorls have both been shown to be genetically controlled. Using data from the Sugarcane Expressed Sequence Tag (EST) Project (SUCEST) database, we have identified all sugarcane proteins and genes putatively involved in reproductive meristem and flower development. Sequence comparisons of known flower-related genes...

When natural resources are exploited, environmental costs and economic benefits are often asymmetric. An example is apparent in the environmental impacts from fossil fuel extraction by hydraulic fracturing. So far, most scrutiny has been focused on water quality in affected aquifers, with less attention paid to broader ecological impacts beyond individual drilling operations. Marcellus Shale methane exploitation in New York State, USA, has been delayed because of a regulatory moratorium, pending evaluation that has been directed primarily at localized impacts. We developed a GIS-based model, built on a hexagonal grid underlay nested within the U.S. Environmental Protection Agency&amp;#8217;s EMAP system, to examine potential cumulative ecological impacts....

During the Equanaute survey (June 1992), fourteen submersible dives were performed between 4950 and 2250 m water depths across the southern slope of the Cote d'Ivoire-Ghana Marginal Ridge (CIGMR), in the eastern Equatorial Atlantic. The CIGMR, a high-standing topographic marginal ridge along the Cote d'Ivoire-Ghana transform margin, is believed to result from a complex structural evolution due to the specific wrench-related rifting between Western Equatorial Africa and Northeastern Brazil, in Early Cretaceous times. In this paper we report and discuss geological observations made during dives, and sample analyses to resolve the lithology, paleoenvironmental conditions, age and origin of the CIGMR. The data help in better characterizing the different...

A geomagnetic paleointensity stack between 0.8 and 3.0 Ma from equatorial Pacific sediment cores
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Yamazaki, T; Oda, H.
We have conducted a paleomagnetic study of six sediment cores taken from the equatorial Pacific, three from the West Caroline Basin and three from the Manihiki Plateau, in order to make a relative paleointensity stack during the Matuyama and late Gauss Chrons. The age of the bottom of the cores ranges from 1.2 to 3.0 Ma. The sediments show little downcore changes in the proxies of magnetic grain size and mineralogy and are hence suitable for estimating relative paleointensity. The age of the cores is controlled by correlating variations in magnetic concentration ( magnetic susceptibility and/or anhysteretic remanent magnetization (ARM)) to target oxygen-isotope (delta(18)O) curves. All cores from the Manihiki Plateau show an upward decrease of the natural...

Autores: Sultan, Nabil; Cattaneo, Antonio; Urgeles, R; Lee, H; Locat, J; Trincardi, F; Berne, Serge; Canals, M; Lafuerza, S.
This study is among the first to examine the genesis of the seafloor and subsurface undulations on the Adriatic continental shelf by integrating stratigraphic information and in situ and laboratory geotechnical measurements. Interpretation of sediment behavior is based on a 32-m-long borehole crossing ( 1) a possible shear plane and ( 2) a silty clay layer at about 20 m below seafloor (mbsf) on which sediment undulations are rooted and could be interpreted as a potential weak layer succession. Our main results in terms of triggering mechanism for the observed undulations show that under an earthquake, liquefaction and/or failure of the silty-clay sediments ( weak layer) leading to deformation of the upper more cohesive sediments is possible only when such...

ABSTRACT Sexual differences in some of the components of the pectoral girdle and forelimb of Chaetophractus villosus (Desmarest, 1804) were investigated by means of geometric morphometrics. A total of 15 scapulae (7 males, 8 females) and 50 humeri-ulnae complexes (24 males, 26 females) were examined. No size differences were detected between sexes for any of the bones, but shape differences were found for the humerus and the ulna that enhance the in-forces or the related in-levers. Females had a more robust humerus, with an enlarged deltoid tuberosity, a more spherical head, higher tubercular and epicondylar widths, and more developed supracondylar crests. The ulna of the females was characterised by a more pronounced curvature along its main axis, a...

ABSTRACT Despite tremendous advancements in the livestock sector, additional opportunities exist to improve even further livestock production around the globe. Forecasting is not an exact science and it relies heavily on past and current knowledge. Improvements in the nutritional sciences (both human and animal) include a better understanding of agents that cause deterioration of human health, improving the quality of animal products, applying effective fetal programming, developing new feeds and feeding strategies, and revisiting longstanding technologies. Improvements in the understanding of the rumen microbiome will enable scientists to increase the fermentation efficiency and, hopefully, select microbial species of greater interest.

In recent years, the debate over the most effective means to stabilize greenhouse gas concentrations in the atmosphere has endorsed multiple approaches and a variety of technologies. Assuring secure storage of anthropogenic carbon dioxide is one of our most pressing global scientific challenges that may contribute to achieving a stable solution over the next several decades. Geological sequestration by injection into deep-sea basalt formations provides unique and significant advantages over other potential storage options, including: (a) vast reservoir capacities with high porosity and permeability, sufficient to accommodate centuries-long U.S. production of fossil fuel CO~2~ at locations within a few hundreds of kilometers of populated areas; (b) chemical...

A global comparison of Argo and satellite altimetry observations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dhomps, A. -l.; Guinehut, S.; Le Traon, Pierre-yves; Larnicol, Gilles.
Differences, similarities and complementarities between Sea Level Anomalies (SLA) deduced from altimeter measurements and dynamic height anomalies (DHA) calculated from Argo in situ temperature (T) and salinity (S) profiles are globally analyzed. SLA and DHA agree remarkably well and, compared to previous studies, Argo dataset allows an improvement in the coherence between SLA and DHA. Indeed, Argo data provides a much better spatial coverage of all oceans and particularly the Southern Ocean, the use of an Argo mean dynamic height, the use of measured salinity profiles (versus climatological salinity), and the use of a deeper reference level (1000 m versus 700 m). The large influence of Argo salinity observations on the consistency between altimetry and...

A database of 15,617 point measurements of dimethylsulfide (DMS) in surface waters along with lesser amounts of data for aqueous and particulate dimethylsulfoniopropionate concentration, chlorophyll concentration, sea surface salinity and temperature, and wind speed has been assembled. The database was processed to create a series of climatological annual and monthly 1 degrees x1 degrees latitude-longitude squares of data. The results were compared to published fields of geophysical and biological parameters. No significant correlation was found between DMS and these parameters, and no simple algorithm could be found to create monthly fields of sea surface DMS concentration based on these parameters. Instead, an annual map of sea surface DMS was produced...

A Global Land Use and Biomass Approach to Reduce Greenhouse Gas Emissions, Fossil Fuel Use and to Preserve Biodiversity
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Riedacker,   Arthur.
As average growth consumptions per capita and world population will continue to grow, the promotion of sustainable developments during the next half a century implies to take into account environmental aspects, local potentialities and futures changes in population as well climatic, economic and social factors. At the global level, land and fossil fuel availability per capita, capacity of absorption of greenhouse gas emissions are considered the most important environmental factors. Whereas at local levels are to be considered preservation or improvement of soil fertility, of water regimes, of quality of air, soil and water. Biodiversity must be taken into account at both levels to cope also with climate change. But as underlined by IPCC lead authors, up...

Autores: Turney, Chris S. M.; Jones, Richard T.; Mckay, Nicholas P.; Van Sebille, Erik; Thomas, Zoë A.; Hillenbrand, Claus-dieter; Fogwill, Christopher J.
A valuable analogue for assessing Earth's sensitivity to warming is the Last Interglacial (LIG; 129–116 ka), when global temperatures (0 to +2 ∘C) and mean sea level (+6 to 11 m) were higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) is uncertain. We report here a global network of LIG sea surface temperatures (SST) obtained from various published temperature proxies (e.g. faunal and floral plankton assemblages, Mg ∕ Ca ratios of calcareous organisms, and alkenone UK′37). We summarize the current limitations of SST reconstructions for the LIG and the spatial temperature features of a naturally warmer world. Because of local δ18O seawater changes, uncertainty in the age models of marine cores, and differences...

A GLOBAL MODEL OF CLIMATE CHANGE IMPACTS ON TIMBER MARKETS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sohngen,   Brent; Mendelsohn,   Robert; Sedjo,   Roger A.
Several papers have now estimated the impact of climate change on national timber markets, but few studies have measured impacts globally.  Further, the literature on impacts has focused heavily on changes in productivity and has not integrated movements of biomes as well.  Here, a dynamic model of ecological change and economic change is developed to capture the impact of climate change on world timber markets.  Climate change is predicted to increase global timber production as producers in low-mid latitude forests react quickly with more productive short-rotation plantations, driving down timber prices.  Producers in mid-high latitude forests, in contrast, are likely to be hurt by the lower prices, dieback, and slower productivity increases because of...

A global monthly climatology of oceanic total dissolved inorganic carbon: a neural network approach

Autores: Broullon, Daniel; Perez, Iz F; Velo, Anton; Hoppema, Mario; Olsen, Are; Takahashi, Taro; Key, Robert M.; Tanhua, Toste; Magdalena Santana-casiano, J.; Kozyr, Alex.
Anthropogenic emissions of CO2 to the atmosphere have modified the carbon cycle for more than 2 centuries. As the ocean stores most of the carbon on our planet, there is an important task in unraveling the natural and anthropogenic processes that drive the carbon cycle at different spatial and temporal scales. We contribute to this by designing a global monthly climatology of total dissolved inorganic carbon (TCO2), which offers a robust basis in carbon cycle modeling but also for other studies related to this cycle. A feedforward neural network (dubbed NNGv2LDEO) was configured to extract from the Global Ocean Data Analysis Project version 2.2019 (GLODAPv2.2019) and the Lamont-Doherty Earth Observatory (LDEO) datasets the relations between TCO2 and a set...

Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits in trophic interactions between sharks found in different habitats. We show that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional pelagic sources, but contain individuals that forage within additional...

Organic agriculture world-wide offers the promise of a future to produce and distribute food and other farm products in a healthy, ecologically sound, truly sustainable and fair way. The full benefits of organic agriculture are just now being realized—from ecosystem services to the provision of healthier food - yet, to reach its full potential organic farming needs to address many challenges. While organic agriculture has grown in strength and is in the most favorable position it has ever been in with respect to market conditions, government policies and international institutional support, it still does not have adequate resources to continue its expansion.  The Technology Innovation Platform of IFOAM (TIPI) has developed a vision and an agenda to advance...

A globalizáció és a konszolidációs számvitel alkalmazása a magyar élelmiszer-gazdaságban
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Simon,   Szilvia.
Aglobális pénzügyi és gazdasági válság kialakulása, a válság világméretű elterjedése számos okra vezethető vissza. Ezek között az okok között elsőként a globalizációt lehet kiemelni. Aglobalizáció folyamatában megfigyelhető a tőke, a szellemi erőforrások, az anyagi javak világméretű koncentrációja. Aglobalizáció egyik kísérőjelenségeként megfigyelhető az a tendencia, hogy a jogilag önálló agrár-, élel¬miszer-ipari és élelmiszer-kereskedelmi vállalkozások egymással érdekeltségi, részesedési viszonyba kerülnek, amelynek hatásaként a vállalkozások között a piaci viszonyok korlátozottá válnak.

A glycoprotein E gene-deleted bovine herpesvirus 1 as a candidate vaccine strain
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Weiss,M.; Brum,M.C.S.; Anziliero,D.; Weiblen,R.; Flores,E.F.
A bovine herpesvirus 1 (BoHV-1) defective in glycoprotein E (gE) was constructed from a Brazilian genital BoHV-1 isolate, by replacing the full gE coding region with the green fluorescent protein (GFP) gene for selection. Upon co-transfection of MDBK cells with genomic viral DNA plus the GFP-bearing gE-deletion plasmid, three fluorescent recombinant clones were obtained out of approximately 5000 viral plaques. Deletion of the gE gene and the presence of the GFP marker in the genome of recombinant viruses were confirmed by PCR. Despite forming smaller plaques, the BoHV-1△gE recombinants replicated in MDBK cells with similar kinetics and to similar titers to that of the parental virus (SV56/90), demonstrating that the gE deletion had no deleterious effects...

Total RNA from lipopolysaccharide (LPS)-stimulated rat macrophages used to treat protoplasts from an Aspergillus nidulans strain originated the RT2 regenerated strain, whose culture supernatant showed anti-inflammatory activity in Wistar rats. The protein fraction presenting such anti-inflammatory activity was purified and biochemically identified. The screening of the fraction responsible for such anti-inflammatory property was performed by evaluating the inhibition of carrageenan-induced paw edema in male Swiss mice. Biochemical analyses of the anti-inflammatory protein used chromatography, carbohydrates quantification of the protein sample, amino acids content analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Total sugar...

The authors found that food retailers would incur sizeable incremental costs depending on the mix of labor and capital utilized if a dual tax structure was imposed.  Thus, the tax savings to consumers then would be offset not only by the recoupment of the lost revenue by government, but also by the incremental costs incurred by the food retailers.

A grazing height target to minimize tiller stem elongation rate in annual ryegrass swards
Provedor de dados: Ciência Rural
Autores: Santos,Gabriela Trevisan; Zanini,Guilherme Doneda; Padilha,Deisy Andrade; Sbrissia,André Fischer.
ABSTRACT: Italian ryegrass (Lolium multiflorum Lam) is one of the most cultivated temperate annual forage crop around the world. Despite that, there is little information about the process of stem elongation during its vegetative growth. This information would be useful for grazing management purposes. Thus, the aim of this study was to assess the herbage accumulation and stem elongation rates in annual ryegrass pastures submitted to intermittent stocking. The experimental design used was a completely randomized 2x2 factorial with three replications. The treatments were defined by the combination of two pre-grazing heights (15 and 25cm) associated with two post-grazing heights (4 and 8cm). The herbage accumulation rates were higher in pastures with 25cm...

A growing oceanic carbon uptake: Results from an inversion study of surface pCO(2) data
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Majkut, Joseph D.; Sarmiento, J. L.; Rodgers, K. B.
Concerted community efforts have been devoted to producing an authoritative climatology of air-sea CO2 fluxes, but identifying decadal trends in CO2 fluxes has proven to be more challenging. The available surface pCO(2) estimates are too sparse to separate long-term trends from decadal and seasonal variability using simple linear models. We introduce Markov Chain Monte Carlo sampling as a novel technique for estimating the historical pCO(2) at the ocean surface. The result is a plausible history of surface pCO(2) based on available measurements and variability inferred from model simulations. Applying the method to a modern database of pCO(2) data, we find that two thirds of the ocean surface is trending toward increasing uptake of CO2, with a mean (year...

Ennek a tartás-1 és üzemeltetés-technológiai2 korszerűségi követelménynek csak a színszerű istállóban, almozott kötetlen tartás és a színszerű istállókban almozatlan kötetlen tartás tudnak eleget tenni. Közülük az alommentes változat – amellyel elsősorban a prognosztizált klímaváltozás miatt kell foglalkozni – még további vizsgálatokat is kíván.

A hazai zöldség- és gyümölcságazat fejlődési kilátásai
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erdesz,   Ferencne.
A magyarországi zöldség- és gyümölcságazat felkészülése az uniós csatlakozásra nem volt igazán eredményes, uniós tagságunk eddigi tapasztalatai, eredményei is felemásak. A csatlakozásnak eddig több a negatív, az ágazat jövőjét veszélyeztető következménye, mint a pozitív hozadéka. A korábbi gyengeségek – alacsony szervezettség, elavult műszaki színvonal, hiányos logisztikai rendszerek, elaprózott birtokstruktúra, szélsőségesen differenciált termelési (gazdálkodási) színvonal – következtében itthon piacvesztés, strukturális feszültségek jöttek létre. Későn és lassan indult meg a gazdák összefogása, együttműködése, értékesítő tevékenységük megszervezése. A termelők gyenge piaci alkuereje kedvezőtlenül befolyásolta mind az értékesítést, mind a...

A HEALTHY SCHOOL MEAL ENVIRONMENT:  FOOD ASSISTANCE RESEARCH BRIEF
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ralston,   Katherine L.; Buzby,   Jean C.; Guthrie,   Joanne F.
A "healthy school meal environment" not only gives students opportunities to make healthy meal choices but also encourages them to do so. The extent to which a healthy school meal environment affects the success of USDA's school meals programs is currently a subject of debate. The policy strategies that can be used to encourage such an environment for the National School Lunch Program (NSLP) and the School Breakfast Program (SBP)also are subjects of debate.  Environmental factors considered to be important include: (1) the nutritional quality, variety, and acceptability of program meals; (2) meal scheduling; (3) nutrition education; and (4) sales of non-USDA ("competitive") foods. Other factors contributing to an overall healthy nutrition environment in...

A HEDONIC APPROACH TO ESTIMATING OPERATION AND MAINTENANCE COSTS FOR NEW YORK MUNICIPAL WATER SYSTEMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schmit,   Todd M.; Boisvert,   Richard N.
A hedonic cost function is used to isolate the operation and maintenance costs for water treatments.  For small systems, costs are substantial for some technologies, but not for others.  When regional differences in input costs are accounted for, small systems located in rural areas may have a cost advantage over similar systems closer to urban centers; however, costs of water treatment to meet Safe Drinking Water Act amendments may still be substantial.

A Hedonic Price Analysis of Corn and Soybean Herbicides
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vassalos,   Michael; Dillon,   Carl R.
Herbicides account for approximately 2.2% of total farm expenses and are applied to more than 80% of farmland in the USA. The widespread adoption of herbicides contributed to the increased and relatively cheaper productivity of modern intensively managed agricultural systems in developed countries. The present study uses a hedonic framework to analyze the effect of selected attributes on the price of corn and soybean herbicides. Two different empirical models were estimated separately for the two crops. The data include information on 51 herbicides, 27 for corn and 24 for soybean crops used in Kentucky. Findings indicate that efficacy against weeds and crop response (illustrates the potential of an herbicide to injure a crop) of herbicides are significant...

Autores: Mendes,A. J. Teixeira.
The cultivation of coffee in the American coffee producing countries is not faced with any serious handicap. The future can not be far distant, however, when it will be necessary to establish new plantations back on the high-priced old exploited lands. Need will be felt for improved varieties. At the same time, it is not known if in a near future the American coffee growers will not be in trouble with diseases as terrible as Hemileia, which the present age of transport cannot restrict to non-American areas. In the program of coffee improvement, interspecific crosses are expected to take a very important place. The introducing of desired characteristics of other species into Coffea arabica by hybridization is made difficult by the fact that, while C....

A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rochette, Sebastien; Le Pape, Olivier; Vigneau, Joel; Rivot, Etienne.
This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated framework for life-cycle modeling: (1) outputs of an individual-based model for larval drift and survival that provided yearly estimates of the dispersion and mortality of eggs and larvae, from spawning grounds to settlement in several coastal nurseries; (2) a habitat suitability model, based on juvenile trawl surveys coupled with a geographic information system, to...

Pequenas propriedades leiteiras no sul do Brasil freqüentemente oferecem água para as vacas em um único bebedouro na sala de ordenha, o que pode limitar o consumo de água, com conseqüências negativas na produção e bem-estar animal. Para testar a influencia da restrição de água e dominância social na ingestão de água e no comportamento, 14 animais (novilhas, vacas em lactação e secas) foram submetidos a dois tratamentos num delineamento do tipo cross-over: acesso à água permanente (APer) ou restrito a uma vez ao dia (ARest) durante 17 dias em cada fase. A ingestão de água foi medida diariamente através de um relógio medidor de vazão acoplado à saída de água e o comportamento foi observado entre os dias 13 e 17 de cada fase, por observação visual direta, das...

A high load of non-neutral amino-acid polymorphisms explains high protein diversity despite moderate effective population size in a marine bivalve with sweepstakes reproduction
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Harrang, Estelle; Lapegue, Sylvie; Morga, Benjamin; Bierne, Nicolas.
Marine bivalves show among the greatest allozyme diversity ever reported in Eukaryotes, putting them historically at the heart of the neutralist-selectionist controversy on the maintenance of genetic variation. Although it is now acknowledged that this high diversity is most probably a simple consequence of a large population size, convincing support for this explanation would require a rigorous assessment of the silent nucleotide diversity in natural populations of marine bivalves, which has not yet been done. This study investigated DNA sequence polymorphism in a set of 37 nuclear loci in wild samples of the flat oyster Ostrea edulis. Silent diversity was found to be only moderate (0.7%), and there was no departure from demographic equilibrium under the...

A high-carbohydrate diet enhances the adverse effect of the S2 allele of APOC3 SstI polymorphism on the TG/HDL-C ratio only in young Chinese females
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Song,Yong Yan; Gong,Ren Rong; Zhang,Zhen; Li,Yuan Hao; Xiao,Li Ying; Zhou,Xue Dong; Fang,Ding Zhi.
Both genetic background and diet have profound effects on plasma lipid profiles. We hypothesized that a high-carbohydrate (high-CHO) diet may affect the ratios of serum lipids and apolipoproteins (apo) differently in subjects with different genotypes of the SstI polymorphism in the apoCIII gene (APOC3). Fifty-six healthy university students (27 males and 29 females, 22.89 ± 1.80 years) were given a washout diet of 54% carbohydrate for 7 days, followed by a high-CHO diet of 70% carbohydrate for 6 days without total energy restriction. Serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apoB100, apoAI, and the APOC3 SstI polymorphism were analyzed. The ratios of serum...

We previously reported that both the high-carbohydrate diet (HCD) and high-fat diet (HFD) given for two months promote lipid deposition and inflammation in the liver and brain of mice. The results obtained indicate a tissue-specific response to both diets. Herein, we compared the effects of HCD and HFD on fatty acid (FA) composition and inflammation in the gastrocnemius muscle. Male Swiss mice were fed with HCD or HFD for 1 or 2 months. Saturated FA (SFA), monounsaturated FA (MUFA), n-3 polyunsaturated FA (n-3 PUFA), and n-6 PUFA were quantified. The activities of stearoyl-CoA desaturase 1 (SCD-1), Δ-6 desaturase (D6D), elongase 6, and de novo lipogenesis (DNL) were estimated. As for indicators of the inflammatory tissue state, we measured myeloperoxidase...

A high-copy T7 Escherichia coli expression vector for the production of recombinant proteins with a minimal N-terminal His-tagged fusion peptide
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Ramos,C.R.R.; Abreu,P.A.E.; Nascimento,A.L.T.O.; Ho,P.L.
We report here the construction of a vector derived from pET3-His and pRSET plasmids for the expression and purification of recombinant proteins in Escherichia coli based on T7 phage RNA polymerase. The resulting pAE plasmid combined the advantages of both vectors: small size (pRSET), expression of a short 6XHis tag at N-terminus (pET3-His) and a high copy number of plasmid (pRSET). The small size of the vector (2.8 kb) and the high copy number/cell (200-250 copies) facilitate the subcloning and sequencing procedures when compared to the pET system (pET3-His, 4.6 kb and 40-50 copies) and also result in high level expression of recombinant proteins (20 mg purified protein/liter of culture). In addition, the vector pAE enables the expression of a fusion...

A high-fructose diet induces changes in pp185 phosphorylation in muscle and liver of rats
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Ueno,M.; Bezerra,R.M.N.; Silva,M.S.; Tavares,D.Q.; Carvalho,C.R.; Saad,M.J.A.
Insulin stimulates the tyrosine kinase activity of its receptor resulting in the tyrosine phosphorylation of pp185, which contains insulin receptor substrates IRS-1 and IRS-2. These early steps in insulin action are essential for the metabolic effects of insulin. Feeding animals a high-fructose diet results in insulin resistance. However, the exact molecular mechanism underlying this effect is unknown. In the present study, we determined the levels and phosphorylation status of the insulin receptor and pp185 (IRS-1/2) in liver and muscle of rats submitted to a high-fructose diet evaluated by immunoblotting with specific antibodies. Feeding fructose (28 days) induced a discrete insulin resistance, as demonstrated by the insulin tolerance test. Plasma...

Rats fed a high-fructose diet represent an animal model for insulin resistance and hypertension. We recently showed that a high-fructose diet containing vegetable oil but a normal sodium/potassium ratio induced mild insulin resistance with decreased insulin receptor substrate-1 tyrosine phosphorylation in the liver and muscle of normal rats. In the present study, we examined the mean blood pressure, serum lipid levels and insulin sensitivity by estimating in vivo insulin activity using the 15-min intravenous insulin tolerance test (ITT, 0.5 ml of 6 µg insulin, iv) followed by calculation of the rate constant for plasma glucose disappearance (Kitt) in male Wistar-Hannover rats (110-130 g) randomly divided into four diet groups: control, 1:3 sodium/potassium...

A highly unstable Holocene climate in the subpolar North Atlantic: evidence from diatoms
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Andersen, C; Koc, N; Moros, M.
A composite record (LO09-14) of three sediment cores from the subpolar North Atlantic (Reykjanes Ridge) was investigated in order to assess surface ocean variability during the last 11 kyr. The core site is today partly under the influence of the Irminger Current (IC), a branch of the North Atlantic Drift continuing northwestward around Iceland. However, it is also proximal to the Sub-Arctic Front (SAF) that may cause extra dynamic hydrographic conditions. We used statistical methods applied to the fossil assemblages of diatoms to reconstruct quantitative sea surface temperatures (SSTs). Our investigations give evidence for different regional signatures of Holocene surface oceanographic changes in the North Atlantic. Core LO09-14 reveal relatively low and...

A 44-year (1958-2001) high-resolution atmospheric hindcast for the whole Mediterranean Basin was performed within the EU-funded Hindcast of Dynamic Processes of the Ocean and Coastal Areas of Europe (HIPOCAS) Project. The long-term hindcasted data set, which comprises several atmospheric parameters at different levels, was produced by means of dynamical downscaling from the NCEP/NCAR global reanalysis using the atmospheric limited area model REMO. The REMO hindcast has been exhaustively validated. On that score, various hindcasted surface parameters, such as 10-m wind field, 2-m temperature and mean sea level pressure, have been compared to satellite data (ERS-1/2 scatterometer) and in-situ measurements from offshore stations.

A high-resolution modeling study of the Western Iberian Margin mean and seasonal upper ocean circulation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Nolasco, Rita; Pires, Ana; Cordeiro, Nuno; Le Cann, Bernard; Dubert, Jesus.
The mean seasonal hydrography and circulation of the Western Iberian Margin (WIM) are studied by means of a high-resolution configuration of the Regional Oceanic Modeling System. A comparison of 5-year model averages for January and July with climatological datasets shows a general good agreement in the reproduction of the mean water mass properties and hydrographic distribution. We find that there is a prevailing tendency for slope poleward flow at about 80-100 km offshore at all latitudes from the surface to 1,500 m with strong vertical coupling. This northward flow, which is mainly along slope and amounts up to 8-10 cm s(-1), exhibits several mean flow recirculation regions on its way and evidences of an offshore pathway of poleward flow.

A high-resolution radiolarian-derived paleotemperature record for the Late Pleistocene-Holocene in the Norwegian Sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dolven, Jk; Cortese, G; Bjorklund, Kr.
Polycystine radiolarians are used to reconstruct summer sea surface temperatures (SSSTs) for the Late Pleistocene-Holocene (600-13,400 C-14 years BP) in the Norwegian Sea. At 13,200 C-14 years BP, the SSST was close to the average Holocene SSST (similar to12degreesC). It then gradually dropped to 7.1degreesC in the Younger Dryas. Near the Younger Dryas-Holocene transition (similar to10,000 C-14 years BP), the SSST increased 5degreesC in about 530 years. Four abrupt cooling events, with temperature drops of up to 2.1degreesC, are recognized during the Holocene: at 9340, 7100 ("8200 calendar years event''), 6400 and 1650 C-14 years BP. Radiolarian SSSTs and the isotopic signal from the GISP2 ice core are strongly coupled, stressing the importance of the...

A high-resolution reconstruction of palaeoceanographic conditions in the glacial Southern Ocean (Scotia Sea and Adelie Land Coast)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Collins, Lewis G.
Antarctic sea-ice is a critical component of the climate system, an enhancer of glacial climate and, as recently hypothesised by modelling studies, a potential driver of the millennial scale climate variability that dominated the last glacial cycle (LGC). Unfortunately a severe lack of glacial sea-ice records from the Southern Ocean has so far prevented the testing of this hypothesis with field data. In this thesis, I present detailed reconstructions of Antarctic sea-ice and ocean conditions derived from diatom assemblages and the first application of highly branched isoprenoid biomarkers to glacial sediments. These sea-ice sensitive proxies were measured in high-resolution, glacial sediment cores from the Scotia Sea (Southwest Atlantic, West Antarctica)...

A high-resolution record of Southern Ocean intermediate water radiocarbon over the past 30,000 years
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hines, Sophia K. V.; Southon, John R.; Adkins, Jess F.
The circulation of intermediate waters plays an important role in global heat and carbon transport in the ocean and changes in their distribution are closely tied to glacial-interglacial climate change. Coupled radiocarbon and U/Th measurements on deep-sea Desmophyllum dianthus corals allow for the reconstruction of past intermediate water ventilation. We present a high-resolution time series of Antarctic Intermediate Water radiocarbon from 44 corals spanning 30 ka through the start of the Holocene, encompassing the transition into the Last Glacial Maximum (LGM) and the last deglaciation. Corals were collected south of Tasmania from water depths between 1430 and 1950 m with 80% of them between 1500 and 1700 m, giving us a continuous record from a narrow...

Neuroleptic drugs such as haloperidol has side effects on extrapyramidal pathways. Tardive Dyskinesia is the most important complication. The most characteristic feature of this Tardive Dyskinesia is involuntary movements of mouth and face. In regard to this problem, the induction of gliosis and cell death in the nervous tissue are considered. In this study, adult Sprague-Dawley rats were used as experimental models. Rats were divided into control and experimental groups. The rats were kept in the animal house under standard conditions during experiments. The control rats were intraperitoneally treated with normal saline for 6 days. The experimental samples were treated for the same time with 2, 5 and 10 mg haloperidol.

At 3 dph (mean +/- S.D., 4.1 +/- 0.1 mm total length, L-T), coinciding with the buccopharynx opening, larvae started to feed exogenously, and the gut consisted of a well-developed buccopharynx, a partially-differentiated oesophagus and an intestine divided in three regions (anterior intestine, intermediate intestine and rectum). Yolk reserves were not completely depleted at the onset of exogenous feeding, and a period of mixed nutrition was observed up to 6 dph (4.3 +/- 0.1 mm L-T) when yolk was definitively exhausted. Important morphological...

A Histopathological, Immunohistochemical and Biochemical Investigation on the in vitro Antioxidant, Myeloprotective, Hematoprotective and Hepatoprotective Effects of Hypericum triquetrifolium Seed Extract Against Cyclophosphamide-Induced Toxicity
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Yildiz,Songul Cetik; Keskin,Cumali; Sahintürk,Varol; Ayhanci,Adnan.
Abstract  The aim of this study was to investigate in vitro antioxidant properties and in vivo protective effects of the methanol extract of the Hypericum triquetrifolium Turra (HT) seed against acute hepatotoxicity, myelotoxicity and hematotoxicity in rats induced by cyclophosphamide (CP). In order to investigate in vivo protective effects of the HT extract on rat tissues, the rats were divided into nine groups. The toxic effects of CP and the protective effects of HT extract on nucleated cells that are produced by bone marrow, serum alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and oxidative stress index (OSI) levels were investigated biochemically. Additionally, liver tissue samples were examined for...

A history of demands: philosophy and agrobiology. The significance of the founding principles of organic farming within the framework of contemporary development
Provedor de dados: Organic Eprints
Autores: BESSON, Y.
Organic farming originally deals with the problematic nature/technique within a holistic view. The order of things inspires organic agronomy and social thoughts on agriculture. The link between what is and what has to be socially is not thinkable within modern right and ethic, but it is in accordance with the ancient philosophy. A. Howard, R. Steiner, H.P. Rusch, M. Fukuoka, found their biology according to this fundamental way of behaving. The biology of those founders stands between various philosophical speculations, esoteric speculations, empirical observations, and scientific approaches. According to the ancient philosophy, these authors are suggesting an imitation of nature based on a cyclic understanding. Human intrusion in nature, although founding...

A Holocene pollen record of savanna establishment in coastal Amapá
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Toledo,Mauro B. de; Bush,Mark B.
The main goal of this study was to investigate how climate and human activities may have influenced ecotonal areas of disjoint savannas within Brazilian Amazonia. The fossil pollen and charcoal records of Lake Márcio (Amapá) were used to provide a Holocene palaeoecological history of this region. Detrended correspondence analysis (DCA) was used to enhance the patterns of sample distribution along the sediment core. A marked vegetation change from closed forests with swamp elements to open flooded savanna at c. 5000 yrs BP was evident from the pollen record. Charcoal analysis revealed a pattern of increased accumulation of particles coincident with the establishment of savannas, suggesting higher fire frequency and human impacts near the lake. A 550-year...

A homage to homology: patterns of copepod evolution
Provedor de dados: Open Marine Archive
Autores: Boxshall, G.; Huys, R.
Lack of attention to determining the homology of character states is recognized as being responsible for the ever increasing numbers of phylogenetic schemes for the Crustacea that appear and disappear so rapidly. Detailed study of musculature. segmentation and setation of the limbs of all 10 orders of copepods revealed numerous phylogenetically informative characters. based on segmental fusion patterns and the presence of individually identified setation elements. Simple counts of limb segments (or of setae) were found to be virtually useless for constructing phylogenies in the copepods. This conclusion can probably be extended to other crustacean groups.

A homolog of the RPS2 disease resistance gene is constitutively expressed in Brassica oleracea
Provedor de dados: Genetics and Molecular Biology
Autores: Malvas,Celia C.; Melotto,Maeli; Truffi,Daniela; Camargo,Luis E.A.
In this study, we identified disease resistance gene homologs in Brassica oleracea and assessed their expression in lines resistant and susceptible to Xanthomonas campestris pv. campestris (Xcc). Two DNA fragments of approximately 2.5 kb (BI-16/RPS2 and Lc201/RPS2) were amplified by PCR from two Brassica lines using primers based on an RPS2 homologous sequence previously described in the Brassica oleracea ecotype B117. The sequences of these fragments shared high similarity (95-98%) with RPS2 homologs from various Brassica species. The digestion of these fragments with restriction enzymes revealed polymorphisms at the Xba I restriction sites. The length polymorphisms were used as a co-dominant marker in an F2 population developed to segregate for...

A Hybrid Approach to the Valuation of Climate Change Effects on Ecosystem Services: Evidence from the European Forests
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ding,   Helen; Silvestri,   Silvia; Chiabai,   Aline; Nunes,   Paulo A.L.D.
In this paper we present a systematic attempt to assess economic value of climate change impact on forest ecosystems and human welfare. In the present study, climate change impacts are downscaled to the different European countries, which in turn constitute the elements of our analysis. First, we anchor the valuation exercise in the Millennium Ecosystem Assessment (MEA) Approach and therefore the link between the different forest ecosystem goods and services, including provisioning, regulating and cultural services, human well-being and climate change. Second, climate change is operationalized by exploring the different storylines developed by the International Panel on Climate Change (IPCC) and applied, downscaled, for each of the European countries under...

A hybrid zone between Bathymodiolus mussel lineages from eastern Pacific hydrothermal vents
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Johnson, Shannon B.; Won, Yong-jin; Harvey, Julio B. J.; Vrijenhoek, Robert C.
Background: The inhabitants of deep-sea hydrothermal vents occupy ephemeral island-like habitats distributed sporadically along tectonic spreading-centers, back-arc basins, and volcanically active seamounts. The majority of vent taxa undergo a pelagic larval phase, and thus varying degrees of geographical subdivision, ranging from no impedance of dispersal to complete isolation, often exist among taxa that span common geomorphological boundaries. Two lineages of Bathymodiolus mussels segregate on either side of the Easter Microplate, a boundary that separates the East Pacific Rise from spreading centers connected to the Pacific-Antarctic Ridge.  Results: A recent sample from the northwest flank of the Easter Microplate contained an admixture of northern...

Autores: Castilho,Camila S.; Gava,Adriana; Freitas,Thales R.O. de.
We describe variation at microsatellite loci and the chromosomal polymorphisms of a hybrid population, and hybridizing populations of Ctenomys minutus (the minor tuco-tuco) from the coastal plain of Rio Grande do Sul, southern Brazil. Cytogenetic analysis and a survey of six microsatellite loci included 101 specimens of C. minutus from the parental populations (2n/AN = 42/74 and 48a/76) and their contact zone. Cytogenetic analysis recorded 26 different karyotypes exhibited by 50 individuals from the hybrid population. Of the 26 karyotypes, only 14% presented a parental-like configuration, and none had the combinations of 2n and AN expected for an F1 hybrid. The remaining karyotypes were alternative hybrid forms, with 2n varying from 42 to 46 and AN from 68...

A hybrid zone of two toad sister species, Rhinella atacamensis and R. arunco (Anura: Bufonidae), defined by a consistent altitudinal segregation in watersheds
Provedor de dados: Revista Chilena de Historia Natural
Autores: CORREA,CLAUDIO; MÉNDEZ,MARCO A; ARAYA,SERGIO; LOBOS,GABRIEL; PALMA,R. EDUARDO.
Delimiting the spatial extension of a hybrid zone is essential to understand its historical origin and to identify the geographical and/or environmental factors which delimit it. Rhinella atacamensis and R. arunco are two sister species which together inhabit Chile between 25° and 38° S. Their distribution limits coincide at about 32° S, where recently it was reported that they hybridize in a small watershed (Pupío creek). Although the genetic evidence suggests that these two species form a hybrid swarm, they are not mixed homogeneously in the entire watershed, but rather are spatially segregated: R. arunco is found in the lower part of the creek and R. atacamensis in the higher part. An extensive exploration north and south of 32° S revealed other...

Provedor de dados: Organic Eprints
Autores: Attanasio, Cláudia Mira; Gandolfi, Sergius; Zakia, Maria José B.; Veniziani Junior, José Carlos Toledo; Lima, Walter de Paula.
Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a...

Autores: ALVES, E. R. de A.
O censo brasileiro de 1980 mostrou implicações em relação a agricultura nacional e, particularmente, em relação a cultura do milho. O ponto fundamental que se encontra nesse censo diz respeito a população nacional que continua a crescer à elevada taxa de 2.48% ao ano. Outro ponto importante é que hoje existe no Brad uma população de 119 milhões de habitantes, cabendo a agricultura brasileira prover easa população de fibras e de alimentos. Esta população, em grande parte, está localizada no meio urbano; cerca de 70% dela vive hoje nas cidades e, pela primeira vez se verifica que o meio rural perdeu população de forma absoluta. Em 1980, cerca de três miihões de pessoas deixaram o meio rural, em relação a 1970. Isto é importante porque o meio rural. em termos...

RESUMO As lesões vertebrais cervicais são relativamente comuns nos equinos. No entanto, são poucas as descrições a respeito desse tema na literatura. Acredita-se que esse fato se deva, em parte, às limitações relacionadas ao diagnóstico. Em virtude de um traumatismo cervical, o animal pode apresentar sinais clínicos de paresia e paraplegia até tetraparesia ou tetraplegia, que podem culminar em estado comatoso e, eventualmente, em morte. Esses sinais clínicos podem ser detectados no exame físico, porém, quando associado à imaginologia (avaliação radiográfica), permite a obtenção de diagnóstico mais preciso da lesão. Consequentemente, um prognóstico mais adequado pode ser estabelecido para o paciente. Em face do exposto, apresenta-se o caso de uma égua...

Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Moreira,José Mauro Magalhães Ávila Paz; Rodriguez,Luiz Carlos Estraviz.
Modelos de planejamento florestal com restrições espaciais resultam em problemas matemáticos combinatoriais de difícil resolução. O procedimento mais apropriado, neste caso, é desenvolver métodos heurísticos, em vez das técnicas tradicionais de programação linear. O objetivo deste trabalho é aplicar, aprimorar e avaliar o desempenho da heurística denominada RazaoR (NOBRE e RODRIGUEZ, 2005), desenvolvido para a solução de problemas de planejamento florestal formulados integralmente com variáveis binárias e de acordo com o modelo Tipo I (JOHNSON e SCHEURMAN, 1977 apud CLUTTER et al., 1992, p. 281). O método incorpora restrições espaciais de conectividade entre os fragmentos de vegetação nativa adjacentes às florestas de produção. O déficit de conectividade...

Autores: Bertonha,C.M.; Valadão,C.A.A.; Cruz,M.H.; Takeda,M.; Cholfe,B.F.
RESUMO Os opioides são utilizados na medicina veterinária na analgesia dos animais, porém há restrição quanto ao uso desses fármacos em equinos, pois podem desencadear alterações gastrintestinais, mas a administração pela via epidural minimiza os efeitos adversos. Assim, oito equinos hígidos foram utilizados em três grupos experimentais, objetivando-se avaliar a influência no trânsito gastrintestinal da injeção epidural de morfina (0,2mg/kg), tramadol (1,0mg/kg) ou NaCl 0,9%. Para a avaliação do trânsito gastrintestinal, foi administrada a lignina purificada e enriquecida (Lipe®), pela via oral, a qual posteriormente foi analisada nas fezes. As fezes foram coletadas para investigação desse marcador, antes da epidural e em intervalos até totalizar 48 horas...

A influência da sazonalidade na manutenção da leptospirose bovina no Rio de Janeiro, Brasil
Provedor de dados: Revista de Educação Continuada em Medicina Veterinária e Zootecnia do CRMV-SP
Autores: Correia, L.; Loureiro, A. P.; Lilenbaum, W.
A leptospirose bovina é uma doença crônica que se manifesta principalmente por problemas reprodutivos, responsáveis por importantes prejuízos econômicos. O status de carreador renal e a eliminação de leptospiras na urina são pontoschave na epidemiologia da leptospirose e a manutenção desse status depende da interação sorovar-hospedeiro. Além disso, a taxa de animais soropositivos aumenta durante os períodos chuvosos, mas o papel da sazonalidade na manutenção da leptospirose bovina ainda não é bem definido. A fim de compreender um pouco mais sobre o papel da sazonalidade na ocorrência da leptospirose bovina, 582 amostras de soro e urina de bovinos de diferentes rebanhos do Estado do Rio de Janeiro foram obtidas em um matadouro regional durante o período de...

Os autores estudam a influência de grãos pretos em ligas com cafés brasileiros de bebida Mole. Foram ensaiadas porcentagens crescentes de grãos pretos: 0, 1, 2, 5, 10, 15, 20, 30, 40 e 50%. Realizaram-se dois ensaios de degustação em blocos incompletos equilibrados, com t = 10 tratamentos, k = 4 parcelas por bloco, r = 6 repetições, b = 15 blocos, X = 2. Cada parcela era formada por 3 xícaras de tipo padrão e foi provada por 3 degustadores, que davam sua opinião xícara por xícara. Os dados coletados são, pois, 1080, isto é, 540 para cada um dos dois ensaios. Mas cada ensaio tinha realmente apenas 60 parcelas, a cada uma das quais correspondia a média das 9 opiniões sôbre ela emitidas (3 degustadores x 3 xícaras). As bases deste método experimental são as...

A influência do espaçamento sôbre o ciclo vegetativo do sisal
Provedor de dados: Bragantia
Autores: Medina,J. C.
The present paper deals with the influence of different rates of spacing on the poling of sisal plants (Agave sisalana Perrine). The results were obtained from spacing trials (four randomized blocks of nine treatments) carried out at the Ribeirão Preto and Pindorama Experimental Stations. The percentages of poling plants, up to the 5th leaf cutting, were 20,0% and 91,7% for the narrowest (1,2 x 2,0 m) and widest (2,0 x 3,0 m) spacings tried in Pindorama, while in Ribeirão Preto they were 12,5% and 02,5%, respectivelly. According to these results it may be concluded that the narrow spaced plants were less liable to early poling than the wide spacing ones. The trial at Ribeirão Preto also indicated that among the plants, grown under the same conditions,...

Autores: Silveira,João Paulo Generoso; Amarante,Cassandro Vidal Talamini do; Steffens,Cristiano André; Miqueloto,Aquidauana; Katsurayama,José Masanori.
O "bitter pit" é um distúrbio fisiológico ocasionado pela deficiência de cálcio (Ca) em maçãs. No entanto, trabalhos recentes mostram que o "bitter pit" pode estar relacionado com aumento na atividade de giberelinas nas plantas. Este trabalho teve como objetivo avaliar os efeitos da pulverização de macieiras com um inibidor da síntese de giberelinas, o prohexadiona-cálcio (ProCa), e com giberelina GA3, no crescimento vegetativo das plantas e na ocorrência de "bitter pit". O experimento foi conduzido em um pomar localizado no município de São Joaquim-SC, na safra de 2009/2010. Macieiras 'Catarina' e 'Fuji' foram pulverizadas com água (tratamento-controle), ProCa e GA3 (ambos os produtos na dose de 319 mg L-1), na queda das pétalas (15-10-2009), quando as...

Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Coleti,Jamile de Campos; Oliveira,Andrea Leda Ramos de.
Resumo: A busca por fontes de energia renováveis tem aumentado a demanda mundial de etanol. O Brasil é o segundo maior produtor; porém, os custos para transportar a produção são cada vez mais altos. O objetivo do presente artigo é analisar as alternativas de transporte para o etanol frente às condições da logística vigentes no Brasil. Para tanto, propõe-se a aplicação de um modelo de equilíbrio parcial na forma de um Problema de Complementaridade Mista (PCM). Foram avaliados três cenários: o primeiro representa uma perspectiva atual e vigente, em que são praticadas rotas rodoviárias e rodoferroviárias. No Cenário 2 estimou-se uma redução de 15% no valor do frete ferroviário e, no Cenário 3, são incluídos novos projetos dutoviários em curso no País. O...

A Joint Characterization of German Monetary Policy and the Dynamics of the German Term Structure of Interest Rates
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fendel,   Ralf.
The paper develops an empirical no-arbitrage Gaussian affine term structure model to explain the dynamics of the German term structure of interest rates.  In contrast to most affine term structure models two risk factors are linked to observable macroeconomics factors: output and inflation.  The results indicate that the dynamics of the German term structure of interest rates can be sufficiently explained by expected variations in those macroeconomic factors plus an additional unobservable factor.  Furthermore, we are able to extract a monetary policy reaction function within this no-arbitrage model that closely resembles empirical reaction functions that are based on the dynamics of the short rate only.

Autores: Goswami, Bedanta K.; Weitemeyer, Karen A.; Minshull, Timothy A.; Sinha, Martin C.; Westbrook, Graham; Chabert, Anne; Henstock, Timothy J.; Ker, Stephan.
We acquired coincident marine controlled-source electromagnetic (CSEM), high-resolution seismic reflection and ocean-bottom seismometer (OBS) data over an active pockmark in the crest of the southern part of the Vestnesa Ridge, to estimate fluid composition within an underlying fluid-migration chimney. Synthetic model studies suggest resistivity obtained from CSEM data can resolve gas or hydrate saturation greater than 5% within the chimney. Acoustic chimneys imaged by seismic reflection data beneath the pockmark and on the ridge flanks, were found to be associated with high-resistivity anomalies (+2-4 m). High-velocity anomalies (+0.3 km/s), within the gas hydrate stability zone (GHSZ) and low-velocity anomalies (-0.2 km/s) underlying the GHSZ, were also...

The Asteraceae, one of the largest families of flowering plants, contains about 1,100 genera and 20,000 species, and is well known for its extensive karyotypic variation. In this study, conventional Feulgen staining, C-CMA3 banding, and fluorescence in situ hybridization with a 45S rDNA probe were used to determine the chromosome number and the number and physical position of GC-rich heterochromatin and 45S rDNA sites in three Asteraceae weed species (Crepis japonica, Galinsoga parviflora and Chaptalia nutans). The three species exhibited karyotype differences in the chromosome number and shape, as a commom feature of Asteraceae. However, the 45S rDNA sites always occurred on the short chromosomal arms, associated with GC-heterochromatin. Althought of...

Autores: Giachini,F.R.C.; Carneiro,F.S.; Lima,V.V.; Carneiro,Z.N.; Brands,M.W.; Webb,R.C.; Tostes,R.C.
Oscillatory contractile activity is an inherent property of blood vessels. Various cellular mechanisms have been proposed to contribute to oscillatory activity. Mouse small mesenteric arteries display a unique low frequency contractile oscillatory activity (1 cycle every 10-12 min) upon phenylephrine stimulation. Our objective was to identify mechanisms involved in this peculiar oscillatory activity. First-order mesenteric arteries were mounted in tissue baths for isometric force measurement. The oscillatory activity was observed only in vessels with endothelium, but it was not blocked by L-NAME (100 µM) or indomethacin (10 µM), ruling out the participation of nitric oxide and prostacyclin, respectively, in this phenomenon. Oscillatory activity was not...

A kinetic energy budget and internal instabilities in the Fine Resolution Antarctic Model
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ivchenko, Vladimir O; Treguier, Anne-marie; Best, Se.
An energy analysis of the Fine Resolution Antarctic Model (FRAM) reveals the instability processes in the model. The main source of time-mean kinetic energy is the wind stress and the main sink is transfer to mean potential energy. The wind forcing thus helps maintain the density structure. Transient motions result from internal instabilities of the Bow rather than seasonal variations of the forcing. Baroclinic instability is found to be an important mechanism in FRAM. The highest values of available potential energy are found in the western boundary regions as well as in the Antarctic Circumpolar Current (ACC) region. All subregions with predominantly zonal flow are found to be baroclinically unstable. The observed deficit of eddy kinetic energy in FRAM...

A növénynemesítés fokozatosan romló működési körülményei, a hatékony marketing és a vetőmagkereskedelem hiányosságai, a külföldi fajták nyomása következtében több növényfajban a hazai nemesítés jelentősége csökkent az utóbbi 20 évben, sőt néhány növényfaj nemesítése Magyarországon meg is szűnt. A Kompolton folyó őszi árpa nemesítés eredményesen állt helyt a külföldi fajtaelőállítók nyomásának.

A 2013 utáni időszakra szóló KAP-reform keretében egyes tagállamok máris felvetették a közvetlen termelői támogatások jelentős csökkentését. Acikk 2006. évi támogatási és jövedelmi adatok alapján azt vizsgálja, hogy egy drasztikus, 50 százalékos támogatáscsökkenésnek milyen hatásai valószínűsíthetők, ha a termelés egyéb feltételei nem változnának. Az elemzés szerint egy ilyen lépésnek Magyarországon sokrétű és rendkívül hátrányos következményei lennének, nemcsak a mezőgazdaságra, hanem az egész nemzetgazdaságra, különösképpen pedig a vidéki foglalkoztatási viszonyokra és a természeti környezetre nézve.

A KÜLFÖLDI TŐKE SZEREPE A MEZŐGAZDASÁGBAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Antal,   Katalin; Guba,   Maria.
A külföldi tőke érdeklődése a magyar mezőgazdaság iránt 87,2 milliárd forint sajáttőke-résszel 2002-ben érte el a csúcsot a KSH adatai szerint. Forintárfolya-mon számolva 1993 és 2001 között 6,3-szeresére nőtt a jegyzett tőkében a külföl-di tőke összege, euróban számolva 2,6-szeres volt a növekedés. A mezőgazdasági termelésben kettős könyvelést vezető gazdaságoknál a kül-földi tőke a jegyzett tőkéből 7,3 milliárd forintról (1993. évi adat) 2000-re 31,5 milliárd forintra emelkedett, majd 2003-ra 24,5 milliárdra csökkent. A két év alatti több mint 20 százalékos visszaesés a külföldi tőke érdekvesztését jelzi. A legnagyobb csökkenés a gabonafélék, egyéb máshova nem sorolt növények szak-ágazatban volt a legnagyobb.

Autores: Wang, Chen; Mouche, Alexis; Tandeo, Pierre; Stopa, Justin; Longépé, Nicolas; Erhard, Guillaume; Foster, Ralph C.; Vandemark, Douglas; Chapron, Bertrand.
The Sentinel‐1 mission is part of the European Copernicus program aiming at providing observations for Land, Marine and Atmosphere Monitoring, Emergency Management, Security and Climate Change. It is a constellation of two (Sentinel‐1 A and B) Synthetic Aperture Radar (SAR) satellites. The SAR wave mode (WV) routinely collects high‐resolution SAR images of the ocean surface during day and night and through clouds. In this study, a subset of more than 37,000 SAR images is labelled corresponding to ten geophysical phenomena, including both oceanic and meteorologic features. These images cover the entire open ocean and are manually selected from Sentinel‐1A WV acquisitions in 2016. For each image, only one prevalent geophysical phenomenon with its prescribed...

A laboratory method to estimate the efficiency of plant extract to neutralize soil acidity
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Cassiolato,Marcelo E.; Miyazawa,Mário; Meda,Anderson R.; Pavan,Marcos A.
Water-soluble plant organic compounds have been proposed to be efficient in alleviating soil acidity. Laboratory methods were evaluated to estimate the efficiency of plant extracts to neutralize soil acidity. Plant samples were dried at 65ºC for 48 h and ground to pass 1 mm sieve. Plant extraction procedure was: transfer 3.0 g of plant sample to a becker, add 150 ml of deionized water, shake for 8 h at 175 rpm and filter. Three laboratory methods were evaluated: sigma (Ca+Mg+K) of the plant extracts; electrical conductivity of the plant extracts and titration of plant extracts with NaOH solution between pH 3 to 7. These methods were compared with the effect of the plant extracts on acid soil chemistry. All laboratory methods were related with soil...

A laboratory model system for analysing microbial interactions occurring in anoxic estuarine sediments.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Herbert, R; Keith, S.
Defined mixed populations of Clostridium butyricum, Desulfovibrio desulfuricans and Chromatium vinosum co-existed for long periods when grown in a single stage chemostat with glucose as sole carbon source. The nature and availability of the inorganic nitrogen source exerted a major effect on carbon flow in the experimental system. The data show that both the C. butyricum and D. desulfuricans isolates can utilise NO sub(3) as an e super(-)acceptor with an increase in cell yield. Under these growth conditions the free S super(2-) levels were lower resulting in more stable mixed populations. In addition the data show that the C. butyricum produces more oxidised fermentation end-products (acetate) when NO sub(3) super(-) was available and more reduced products...

Autores: Zhong,Chen; Zhen,Ding; Qian,Qi; Genshan,Ma.
We investigated the association between two single nucleotide polymorphisms (SNPs) in the adiponectin gene (rs822395 and rs266729) and coronary artery disease (CAD) in a case-control study of 198 unrelated Chinese CAD patients (with ; 70% coronary stenosis or previous myocardial infarction) and 237 non-CAD controls. The ligase reaction was used to detect SNPs rs822395 and rs266729, and the allelic association of these SNPs with the occurrence and severity of CAD was assessed. There were no significant differences in the genotypic or allelic frequencies of the two SNPs between control and CAD individuals. In addition, there was no association between the two SNPs and the severity of CAD based on the number of diseased vessels. The frequencies of alleles C...

A large waterborne outbreak of infection that occurred during August 2000 in a local community in France was investigated initially via a rapid survey of visits to local physicians. A retrospective cohort study was then conducted on a random cluster sample of residents. Of 709 residents interviewed, 202 (28.5%) were definite cases (at least three liquid stools/day or vomiting) and 62 (8.7%) were probable cases (less than three liquid stools/day or abdominal pain). Those who had drunk tap water had a three-fold increased risk for illness (95% CI 2.4-4.0). The risk increased with the amount of water consumed (chi-square trend: p &lt; 0.0001). Bacteriological analyses of stools were performed for 35 patients and virological analyses for 24 patients....

A late Quaternary planktonic foraminiferal oxygen isotope record of the Banda Sea: Chronostratigraphy, orbital forcing, and paleoceanographic implications
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chen, Chih-wei; Wei, Kuo-yen; Mii, Horng-sheng; Yang, Tien-nan.
A detailed oxygen isotope time-scale based on planktonic foraminifera Globigerinoides sacculifer at site MD012380 in the Banda Sea was established for the past 820 kyrs by correlating the record to the astronomically tuned benthic oxygen isotope chronology of MD972143. Ages for marine isotope stratigraphic (MIS) events from 2.0 back to 21.1 were designated for this western tropical Pacific record. Spectral analysis of the 6180 time-series reveals distinct periodicities of 100, 41, and 23 kyrs, indicating strong orbital forcing, yet the power of each band varies through time. The time-series of three other paleo-proxies, namely, coarse fraction (CF), lightness of sediments and delta C-13 of Globigerinoides saccidifer, were subjected to cross-spectral...

Autores: Counts, John; Jorry, Stephan; Vazquez Riveiros, Natalia; Jouet, Gwenael; Giraudeau, Jacques; Cheron, Sandrine; Boissier, Audrey; Miramontes, Elda.
A 27 m core collected on the seafloor near Juan de Nova island at 1909 m depth in the SW Indian Ocean preserves a high‐resolution record of carbonate sediment export to the deep sea over the past 1 Myr. Core chronology was established using calcareous nannofossil biostratigraphy and benthic foraminiferal δ18O. Throughout the core, preserved highstand intervals (MIS 1, 5, 7, 9, 11, 13, 15, 23 and 25) are marked by an increase in the aragonite content within the sediment. Aragonite is likely sourced from the nearby Juan de Nova carbonate platform ~10 km to the south, and is interpreted to result from flooding of the platform top. Platform inundation allows carbonate muds to be winnowed from their original shallow‐water environment of deposition, suspended in...

Autores: Lartaud, Franck; Emmanuel, Laurent; De Rafelis, Marc; Ropert, Michel; Labourdette, Nathalie; Richardson, Christopher A.; Renard, Maurice.
Cathodoluminescence (CL) microscopy of the foliated calcite shell hinge sections of live-collected oyster Crassostrea gigas collected at seven locations along a latitudinal gradient from the Netherlands in the North Sea to the Atlantic coast of France, revealed variations in luminescence that were attributable to seasonal variations in calcification of the hinge. Photomicrographs of hinge sections and luminescence profiles were analyzed to define a micro-sampling strategy that was adopted to drill the hinge samples to determine their isotopic composition. Reconstructed seasonal seawater temperatures determined from the stable oxygen isotope (delta O-18) composition along growth profiles from 32 oyster shell hinges showed distinct seasonal isotopic cycles...

A latitudinal productivity band in the central North Atlantic over the last 270 kyr: An alkenone perspective
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Villanueva, J; Calvo, E; Pelejero, C; Grimalt, Jo; Boelaert, A; Labeyrie, L.
Productivity changes in the central North Atlantic Ocean have been traced by means of the total C-37 alkenone contents along two sediment cores located at 43 degreesN and 37 degreesN. Both alkenone signals revealed the occurrence of discrete productivity events every 23 kyr. Spectral analyses highlight the presence of a dominant 23-kyr periodicity in the alkenone signal, which is highly coherent to the precession index. However, a close comparison revealed small but relevant differences in the timing of several of the productivity events recorded at both locations. These asynchronies suggest that the alkenone maxima do not necessarily reflect a general increase of productivity over the North Atlantic. We propose that the events are related to a latitudinal...

A leaf anatomical contribution to the classification of the Linaceae complex
Provedor de dados: Naturalis Digital Academic Repository
Autores: Welzen, P.C. van; Baas, P.
The leaf anatomy of the Linaceae complex (Linaceae s.s., Hugoniaceae, Ixonanthaceae, Humiriaceae and Erythroxylaceae) and putative allies ( Ctenolophon, Lepidobotrys, Irvingiaceae) is surveyed, mostly on the basis of original observations (72 specimens, 27 genera), partly from data in the literature. Diversity in stomatal type, midrib and petiole vascularisation, sclerenchyma support, foliar sclereids, mucilage cells, secretory cavities, and cristarque cells provide evidence in favour of a separate family status of the members of the Linaceae complex. Allantospermum and Cyrillopsis are best accommodated in the Ixonanthaceae. Irvingiaceae (often treated in or near Simaroubaceae) show similarities with the Linaceae complex, albeit more closely to the...

Autores: Neves,Reizaluamar de Jesus; Souza,Leonardo Silva; Oliveira,Eder Jorge de.
ABSTRACT The slow rate of multiplication is one of the main constraints on the production of cassava (Manihot esculenta Crantz). This work aimed to evaluate the use of leaf buds for rapid propagation of cassava varieties. Leaf buds were excised from three cassava varieties (BRS Kiriris, 98150-06 and 9624-09) for plantlet generation. The experiment was completely randomized with a 5 (age of mother plant) × 3 (position of the leaf buds on the stems) × 2 (agrochemical treatments) factorial design. Data were collected on leaf sprouting percentage (Spro.Per), plantlet height (Plant.Hei) and total dry mass of plantlets (Dry.Mass.Plant). There was a difference between the three traits for most of the varieties, demonstrating significant effects on the agronomic...

A legume genomics resource: The Chickpea Root Expressed Sequence Tag Database
Provedor de dados: Electronic Journal of Biotechnology
Autores: Jayashree,B; Buhariwalla,Hutokshi K; Shinde,Sanjeev; Crouch,Jonathan H.
Chickpea, a lesser-studied grain legume, is being investigated due to its taxonomic proximity with the model legume genome Medicago truncatula and its ability to endure and grow in relatively low soil water contents making it a model legume crop for the study of agronomic response to drought stress. Public databases currently contain very few sequences from chickpea associated with expression in root tissues. However, root traits are likely to be one of the most important components of drought tolerance in chickpea. Thus, we have generated a set of over 2800 chickpea expressed sequence tags (ESTs) from a library constructed after subtractive suppressive hybridization (SSH) of root tissue from two closely related chickpea genotypes possessing different...

Autores: Porto-Foresti,Fábio; Oliveira,Claudio; Gomes,Eduardo A.; Tabata,Yara A.; Rigolino,Marcos G.; Foresti,Fausto.
Cytogenetic analysis of a rainbow trout stock showed that the nucleolar organizing regions were located subterminally on the long arm of a submetacentric chromosome pair and occurred as a single chromosomal segment (phenotype N1) or as two chromosomal segments separated by a short euchromatic segment (phenotype N2). Cytogenetic analysis also showed that there were N1N1 and N1N2 individuals but no N2N2 individuals. Analysis of the different includedphenotypes incluted that the population was not in Hardy-Weinberg equilibrium (chi² = 19.333; p &lt; 0.01), and that a higher frequency of individuals had the N1N2 phenotype. Experimental crosses involving four males (two N1N1 and two N1N2) and four females (one N1N1 and three N1N2) yielded eight broods. There...

A LIGHT AIRCRAFT AS A LOW-FREQUENCY SOUND SOURCE FOR ACOUSTICAL OCEANOGRAPHY
Provedor de dados: Gayana
Autores: Buckingham,Michael J; Giddens,Eric M.
The sound from a propeller-driven aircraft is largely generated by the propeller itself. Its acoustic signature consists of a series of harmonics, the lowest of which, the fundamental, is typically in the region of 100 Hz, with the higher harmonics appearing at multiples of the fundamental. Experiments have recently been conducted off the coast of southern California, using several different types of single-engine, light aircraft, which show that the first 10 or so propeller harmonics are detectable not in the atmosphere, in the water column and also on sensors buried to a depth of about 1 m in the seabed. The Doppler-shifted comb of frequencies produced by an aircraft propeller is the basis of a recently developed technique for making point measurements...

A likely role for a novel PH-domain containing protein, PEPP2, in connecting membrane and cytoskeleton
Provedor de dados: Biocell
Autores: Zou,Yi; Zhong,Wenping.
PH domains (pleckstrin homology) are well known to bind membrane phosphoinositides with different specificities and direct PH domain-containing proteins to discrete subcellular apartments with assistances of alternative binding partners. PH domain-containing proteins are found to be involved in a wide range of cellular events, including signalling, cytoskeleton rearrangement and vesicular trafficking. Here we showed that a novel PH domain-containing protein, PEPP2, displayed moderate phosphoinositide binding specificity. Full length PEPP2 associated with both plasma membrane and microtubules. The membrane-associated PEPP2 nucleated at cell-cell contacts and the leading edge of migrating cells. Overexpression of PEPP2 increased membrane microviscosity,...

ABSTRACT Some germplasm collections have a high number of accessions, which makes it difficult to explore the genetic variability present in the germplasm bank due to the redundancy and the difficulty of detailed analysis of all conserved accessions. Therefore, our study aimed to analyze the genetic diversity of 153 lima bean (Phaseolus lunatus) accessions for the purpose of constructing a core collection. Eleven SSRs were used for this purpose. The 153 lima bean accessions can be represented by low redundancy using a minimum of 34 accessions, thus representing 22 % of the size of the entire germplasm bank. The core collection had a higher Shannon diversity index and expected heterozygosity (1.906 and 0.811, respectively) than those presented by the entire...

A Limit for Antler Length in Captive Marals
Provedor de dados: International Journal of Morphology
Autores: Korzhikenova,N; Sambetbaev,A; Iglikov,O; Parés-Casanova,P. M.
The main aim of this study was to estimate phenotypic correlations among live weight, withers height, rump height, chest depth, chest width, thoracic girth, body length, hip widths (between iliac tuberosities and between ischial tuberosities) and forelimb cannon perimeter with antler length measured during the growth of marals on a Kazakh farm. The data comprised 18 animals studied during their growth (at 18 months and at 24 months). In maral, the first period of antler productivity takes place at the age of 24 months. This fact should be taken into account in order to select the best animals for antler production, which is the main purpose for farming this species.

A Linearized Almost Ideal Demand System (LA/AIDS) Estimation of the Demand for Meat in South Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Taljaard,   Pieter R.; Alemu,   Zerihun Gudeta; van Schalkwyk,   Herman D.
A linear approximated Almost Ideal Demand System (LA/AIDS), estimated in first differences, were used to estimate the demand relations for meat (beef, chicken, pork and mutton) in South Africa from 1970 –2000.  Two tests for weak separability, including an F and Likelihood ratio version, failed to reject the null hypothesis of weak seperability, confirming that the four meat products are separable, and should be modelled together.  According to the Hausman exogeneity test, the expenditure term in the South African meat demand model is exogenous.  As a result, a Restricted Seemingly Unrelated Regression (RSUR) was used to estimate the model, whereafter the estimated parameters were used to estimate compensated, uncompensated and expenditure elasticities.

A Linguistic Approach to Aligning Representations of Human Anatomy and Radiology
Provedor de dados: Nature Precedings
Autores: Pinar Wennerberg; Manuel M&amp;#xf6;ller; Sonja Zillner.
To realize applications such as semantic medical image search different domain ontologies are necessary that provide complementary knowledge about human anatomy and radiology. Consequently, integration of these different but nevertheless related types of medical knowledge from disparate domain ontologies becomes necessary. Ontology alignment is one way to achieve this objective. Our approach for aligning medical ontologies has three aspects: (a) linguistic-based, (b) corpus-based, and (c) dialogue-based. We briefly report on the linguistic alignment (i.e. the first aspect) using an ontology on human anatomy and a terminology on radiology.

Autores: Padilha,H.G.; Crispim,C.A.; Zimberg,I.Z.; De-Souza,D.A.; Waterhouse,J.; Tufik,S.; de-Mello,M.T.
The present review evaluates the role of sleep and its alteration in triggering problems of glucose metabolism and the possible involvement of adipokines in this process. A reduction in the amount of time spent sleeping has become an endemic condition in modern society, and a search of the current literature has found important associations between sleep loss and alterations of nutritional and metabolic contexts. Studies suggest that sleep loss is associated with problems in glucose metabolism and a higher risk for the development of insulin resistance and type 2 diabetes mellitus. The mechanism involved may be associated with the decreased efficacy of regulation of the hypothalamus-pituitary-adrenal axis by negative feedback mechanisms in...

Autores: Rossato,Janine I.; Zinn,Carolina G.; Furini,Cristiane; Bevilaqua,Lia R.M.; Medina,Jorge H.; Cammarota,Martín; Izquierdo,Iván.
Two major memory systems have been recognized over the years (Squire 1987): the declarative memory system, which is under the control of the hippocampus and related temporal lobe structures, and the procedural or habit memory system, which is under the control of the striatum and its connections. Most if not all learning tasks studied in animals, however, involve either the performance or the suppression of movement; this, if learned well, may be viewed as having become a habit. It is agreed that memory rules change from their first association to those that take place when the task is mastered. Does this change of rules involve a switch from one memory system to another? Here we will comment on: 1) reversal learning in the Morris water maze (MWM), in...

 The effects of microcapsule diet as co-feeding for early weaning phase of gourami larvae where evaluated in terms of ingestion rate of microcapsule, growth, and survival rate. The availability of tubifex worms as natural food is uncertain and can introduce pathogens to fish culture from outside environment. Therefore, the attempt to replace or substitute this natural food continues in order to reduce the level of dependence. This research used Complete Randomized Designed (CRD) with four treatments based on a different protocol feeding management. Gourami larvae should be started with the co-feeding on day 12 until day 17 and they are more receptive to microcapsule diets after day 17. The ingestion rate of microcapsule which consumed by the larvae during...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Cardoso,T.C.; Mouro-Sousa,R.L.; Oliveira,C.; Stringhini,G.; Augusto-Pinto,A.
A liquid phase blocking ELISA (LPB-ELISA) was developed for the detection and measurement of antibodies against infectious bronchitis virus (IBV). The purified and nonpurified virus used as antigen, the capture and detector antibodies, and the chicken hyperimmune sera were prepared and standardized for this purpose. A total of 156 sera from vaccinated and 100 from specific pathogen-free chickens with no recorded contact with the virus were tested. The respective serum titers obtained in the serum neutralization test (SNT) were compared with those obtained in the LPB-ELISA. There was a high correlation (r2 = 0.8926) between the two tests. The LPB-ELISA represents a single test suitable for the rapid detection of antibodies against bronchitis virus in...

A literature review of the pollination strategies and breeding systems in Oncidiinae orchids
Provedor de dados: Acta Botanica Brasilica
Autores: Castro,Jonas B.; Singer,Rodrigo B.
ABSTRACT Oncidiinae is an exclusively Neotropical orchid subtribe with about 1600 described species and an impressive array of vegetative and floral morphological adaptations. We present the results of a literature survey on the pollination strategies and breeding systems of this orchid subtribe. The flowers are pollinated by a wide range of insects (mostly bees) and, sometimes, hummingbirds. Several genera reward their pollinators with floral resources such as oils, nectar or perfumes. Whereas pollination by oil-gathering bees likely evolved several times within Oncidiinae, exclusive pollination by perfume-gathering male Euglossine bees is likely restricted to a set of closely-related genera. Pollination by food or sexual deception is also present within...

A Long Memory Conditional Variance Model for International Grain Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jin,   Hyun Joung.
The study explores a long memory conditional volatility model on international grain markets, demonstrating importance of modeling both temporal effects of volatility and long memory process. This study adopts six different volatility models, nested in an ARMA(p,q)- FIGARCH(P,D,Q), to capture dependence of grain cash price volatility and compares the performance of the six models. It also visits a related question about non-normal behaviors of grain prices and adopts the student-t density intended to account for fat-tailed properties of the data. We find suitability of the FIGARCH type models under the student-t distribution and competitiveness of the parsimonious FIGARCH(1,d,0) for modeling long memory volatility.

Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Berthe, Franck.
Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the...

A  Longitudinal Study of Mastitis on an Experimental Farm with Two Herds, One Managed Organically, the other Conventionally
Provedor de dados: Organic Eprints
Autores: Thatcher, A; Petrovski, K; Holmes, C; Dowson, K; Kelly, T; McLeod, K.
Mastitis in two herds managed as a comparison between organic and conventional dairy farming systems was monitored for 4 years utilising regular bacterial culture of milk samples, individual and bulk somatic cell counts and observation by farm staff. The objective was to develop strategies for the control of mastitis in organic cows without the use of antibiotics. The herds showed differences in clinical mastitis incidence, subclinical mastitis prevalence and bulk milk somatic cell count. Despite these differences, the level of mastitis in the organic herd remained manageable.

A Lux-like Quorum Sensing System in the Extreme Acidophile Acidithiobacillus ferrooxidans
Provedor de dados: Biological Research
Autores: RIVAS,MARIELLA; SEEGER,MICHAEL; HOLMES,DAVID S; JEDLICKI,EUGENIA.
The genome of the acidophilic, proteobacterium Acidithiobacillus ferrooxidans, contains linked but divergently oriented genes, termed afeI and afeR, whose predicted protein products are significantly similar to the LuxI and LuxR families of proteins. A possible promoter and Lux box are predicted upstream of afeI. A cloned copy of afeI, expressed in E. coli, encodes an enzyme that catalyzes the production of a diffusible compound identified by gas chromatography and mass spectrometry as an unsubstituted N-acyl homoserine lactone (AHL) of chain length C14. This AHL can be detected by a reporter strain of Sinorhizobium meliloti Rm41 suggesting that it is biologically active. The reporter strain also responds to extracts of the supernatant of A. ferrooxidans...

ABSTRACT This study proposes eight stages according to the main discernible changes recorded throughout the embryonic development of Jenynsia multidentata. The development of morphological embryo structures, pigmentation, and changes in tissues connecting mother and embryo were included in the stage characterization. From the fertilized egg (Stage 1), an embryo reaches the intermediary stages when presenting yolk syncytial layer (Stage 2), initial pigmentation of the outer layers of the retina and dorsal region of the head (Stage 3), and the sprouting of the caudal (Stage 4), dorsal and anal fins (Stage 5). During the later stages, the ovarian folds enter the gills, and the body pigmentation becomes more intense (Stage 6), the body becomes elongated (Stage...

A magyar agrárgazdaság helyzete

Autores: Kapronczai,   Istvan; Udovecz,   Gabor.
A 2008. év második felében kirobbant és fokozatosan elmélyülő pénzügyi-gazdasági válság súlyos piacvesztést eredményezett a magyar nemzetgazdaságban. Az ipari termékek külpiaca beszűkült, az építőipar pedig a fizetőképes kereslet csökkenése folytán került válságba. Ezekben az ágazatokban drasztikusan emelkedett a munkanélküliség. A válság kisebb mértékben érintette az élelmiszer-gazdaságot, amely elsősorban annak tulajdonítható, hogy keresletcsökkenés legkevésbé az élelmiszer-gazdaság termékeinél jelentkezett. Levonható az a következtetés, hogy a válságkezelésben stabilizáló tényező lehet az élelmiszer-gazdaság. Ezt igazolja, hogy az agrárgazdaság termékkibocsátása 2008-ban is jelentősen növekedett, s lényegében ez tette lehetővé a 2008-ban bekövetkezett –...

A szántóföldi növények nemzeti kiegészítő támogatása ugyan 2008-tól a termeléstől függetlenedik, de a gazdálkodók a rendelkezésre álló szántóterületet a jövőben is hasznosítják, mert a gabonafélék magas ára ösztönzi a termelést. A kidolgozott különböző modellváltozataink szerint a hazai búzatermelés 4,6-6,1 millió tonna, míg a kukoricatermelés 9-10,9 millió tonna között alakulhat 2013-ban. A hazai abrakfogyasztó...

A dinamikusan fejlődő gazdaságú vagy a feltörekvő országokban, elsősorban Indiában, Kínában és Oroszországban mind több az állati eredetű termékek iránti igény. Termelésük azonban nem képes lépést tartani a fizetőképes kereslet növekedésével, ezért mind mezőgazdasági alapanyagokból, mind magas feldolgozottságú termékekből importra szorulnak. Az állati eredetű termékek előállításának növeléséhez azonban egyre több takarmány szükséges, nő a gabonafélék és olajnövények iránti globális igény is.

Különböző modellváltozataink szerint a szarvasmarha-állomány 680-731 ezer egyed, a tejelőtehén-állomány 266-269 ezer egyed között alakulhat 2013-ban. Továbbra is elsősorban a húshasznú egyedek számának növekedésére lehet számítani. A tejtermelés 2010-ben várhatóan kitölti a nemzeti kvótát. Tej- és tejtermék-kivitelben főként a...

Autores: Louzada-Júnior,P.; Freitas,M.V.C.; Oliveira,R.D.R.; Deghaide,N.H.S.; Conde,R.A.; Bertolo,M.B.; Donadi,E.A.
The objective of the present study was to evaluate the contribution of the shared epitope (SE), the rheumatoid arthritis (RA) protection model, and the occurrence of anti-cyclic citrullinated peptide (anti-CCP) antibodies in RA patients from a genetically diverse population. One hundred and forty Brazilian RA patients and 161 matched controls were typed for HLA-DRB1 alleles using amplified DNA hybridized with sequence-specific oligonucleotide probes or primers. Patients were stratified according to the presence or absence of SE (DRB1*0401, *0404, *0405, *0101, *1001, and *1402), of the DERAA alleles (DRB1*0103, *0402, *1102, *1103, *1301, *1302, and *1304), and X (all other alleles). Anti-CCP antibodies were measured by ELISA. The combined frequency of...

A male-sterile mutation in soybean (Glycine max) affecting chromosome arrangement in metaphase plate and cytokinesis
Provedor de dados: Biocell
Autores: Pires Bione,Nilton Cesar; Suely Pagliarini,Maria; Alves de Almeida,Leones.
A spontaneous male-sterile, female-fertile mutation affecting bivalent arrangement at the metaphase plate and cytokinesis was detected in line BR98-197 of the soybean breeding program developed by Embrapa - National Soybean Research Centre. Untill diakinesis, meiosis was normal with chromosome pairing as bivalents. From this phase, in several meiocytes, bivalents were not able to organize a single metaphase plate and remained scattered in the cytoplasm in a few or several groups. In these meiocytes, chromosomes segregated in both divisions giving rise to several micronuclei. However, the main cause of male sterility was the absence of cytokinesis after telophase II. Instead of the typical tetrads of microspores, four nucleate coenocytic microspores were...

A management strategy evaluation framework for Mediterranean Atlantic bluefin tuna
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kell, L. T.; Fromentin, Jean-marc.
This paper presents an example of Management Strategy Evaluation (MSE) for Mediterranean and East Atlantic bluefin tuna using the FLR open source framework. Scenarios corresponding to alternative plausible hypotheses about the stock dynamics were used to evaluate alternative management strategies and to test their robustness to implementation error e.g. catch mis-reporting. The strategies evaluated correspond to i) harvest control rule (HCR) based upon F0.1 (a proxy for FMSY ) with an objective of restoring the stock to a level that would “ permit the maximum sustainable catch” and ii) a reduction of fishing mortality on immature fish. The main conclusions were that the F0.1 HCR alone would not result in the recovery of the stock in the next 15 years and...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Leroy, Celine; Delbarre Ladrat, Christine; Ghillebaert, F; Rochet, Marie-joelle; Compere, Chantal; Combes, D.
Aims: To develop a method to screen antifouling agents against marine bacterial adhesion as a sensitive, rapid, quantitative microplate fluorescent test.  Methods and Results: Our experimental method is based on a natural biofilm formed by mono-incubation of the marine bacterium Pseudoalteromonas sp. D41 in sterile natural sea water in a 96 wells polystyrene microplate. The 4'6-diamidino-2-phenylindole (DAPI) dye was used to quantify adhered bacteria in each well. Total measured fluorescence in wells was correlated with the amount of bacteria showing a detection limit of one bacterium per 5 µm2 and quantifying 2 x 107 to 2 x 108 bacteria adhered per cm2. The antifouling properties of three commercial surface active agents and chlorine were tested by this...

A marketing-finance approach linking contracts in agricultural channels to shareholder value
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pennings,   Joost M.E.; Wansink,   Brian; Hoffmann,   Arvid O.I.
A conceptual marketing-finance framework is proposed which links channel contracting in agriculture and the use of financial facilitating services (e.g., financial derivatives) to (shareholder) value creation. The framework complements existing literature by explicitly including channel contract relationships as market-based assets that can be managed to reduce cash flow volatility and hence increase shareholder value. We show how financial facilitating services (e.g., derivatives) can be used to complement the cash flows components of channel contract relationships thereby further reducing the risk adjusted cost of capital and improving shareholder value. In a field study of producers, wholesalers, and processors, in the potato and meat industry the...

Autores: Van, Mai Viet; Phuong, Nguyen Thanh; Dinh, Tran Dac; Villanueva, Ching-maria; Moreau, Jacques.
A mass-balance Ecopath model of coastal areas in the Mekong Delta has been constructed for a quantitative description of the trophic structure of the ecosystem. The model is used to estimate the important biological parameters and relationships among the different ecologically important groups. The model is based on the data collected from bottom trawling. There are 14 functional groups based on 58 species from coastal areas in the Mekong Delta survey such as shrimps, squids, crabs, mackerel, small pelagics, demersal fishes, benthic feeders, predator fishes and trash fish. The biomass value was estimated from catch production and bottom trawling surveys. Results show that the estimated total biomass of exploited resources was 3.99 ton.km-2. The values of...

A Mata Geweke–Hajivassiliou–Keane multivariate normal simulator
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gates,   Richard.
An accurate and efficient numerical approximation of the multivariate normal (MVN) distribution function is necessary for obtaining maximum likelihood estimates for models involving the MVN distribution. Numerical integration through simulation (Monte Carlo) or number-theoretic (quasi–Monte Carlo) techniques is one way to accomplish this task. One popular simulation technique is the Geweke–Hajivassiliou–Keane MVN simulator. This paper reviews this technique and introduces a Mata function that implements it. It also computes analytical first-order derivatives of the simulated probability with respect to the variables and the variance–covariance parameters.

RESUMO Poças temporárias são importantes ampliadores da biodiversidade local, sobretudo em áreas florestadas estacionais. Alterações na cobertura vegetal ao longo das margens desses corpos hídricos podem alterar a composição e estrutura da sua comunidade zooplanctônica. Nesse sentindo, testamos a hipótese de que a presença de mata ripária altera a estrutura da comunidade zooplanctônica encontrada em poças temporárias. Foram filtrados até 10 litros de água, em malha de 20 µm, em poças com (CM) e sem mata ripária (SM), e coletados dados de clorofila-α e as variáveis limnológicas. Todos os espécimes foram identificados com microscópio óptico em câmara de Sedgewick-Rafter. Os dados foram tratados quanto à composição e estrutura da comunidade (riqueza,...

Provedor de dados: Revista de Protección Vegetal
Autores: Miranda,Ileana; Gómez,Lucila; Benítez,Hugo L.; Castillo,Yoannia; Hernández-Ochandía,Dainé; Rodríguez,Mayra G.
Some aspects of Meloidogyne spp. (root-knot nematode) growth regulation by the gram-negative bacterium Pasteuria penetrans were reviewed. The study allowed the construction of a mathematical model to predict the dynamics of both organisms. The model includes 11 differential equations and 31biological constants describing the life-cycle of the nematode and its relationship with the bacterium. To simulate the real behavior of the populations, the constants, which represent biological parameters, have to be evaluated under controlled conditions similar to those of soil microcosm.

Provedor de dados: Revista Ciência Agronômica (RCA)
Autores: Meneghetti,Carlos Renato; Tizzei,Alexandre; Cappelli,Nelson Luis; Umezu,Claudio Kiyoshi; Bezzon,Guilherme.
Studies of control strategies for refrigeration systems observe, among other variables, the dynamic behavior of temperature and the consumption of electrical energy. Aiming to contribute to these studies, this work presents the proposal and validation of a mathematical model for the cooling system of a cold-storage unit. The model approximates the dynamics and interdependence of the variables, to first-order systems with time delay and the summation of effects. The input variables available are the frequency of compressor activation and the thermal load imposed on the unit, and as output variables, the air temperature both at the evaporator inlet and at the centre of the chamber, as well as the electrical power consumed by the compressor. The results...

A mechanistic view of mitochondrial death decision pores
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Belizário,J.E.; Alves,J.; Occhiucci,J.M.; Garay-Malpartida,M.; Sesso,A.
Mitochondria increase their outer and inner membrane permeability to solutes, protons and metabolites in response to a variety of extrinsic and intrinsic signaling events. The maintenance of cellular and intraorganelle ionic homeostasis, particularly for Ca2+, can determine cell survival or death. Mitochondrial death decision is centered on two processes: inner membrane permeabilization, such as that promoted by the mitochondrial permeability transition pore, formed across inner membranes when Ca2+ reaches a critical threshold, and mitochondrial outer membrane permeabilization, in which the pro-apoptotic proteins BID, BAX, and BAK play active roles. Membrane permeabilization leads to the release of apoptogenic proteins: cytochrome c, apoptosis-inducing...

A magyar gazdaság energiaszükségletében meghatározóak a fosszilis eredetű tüzelőanyagok – kőolaj, földgáz, kőszén, illetve ezek származékai –, amelyek kimerülőben vannak, így növelik függőségünket, károsítják környezetünket. Ezért fokozott figyelmet kell fordítani az alternatív energiaforrásokra, amelyekről ma még az a véleményünk, hogy kimeríthetetlenek, kevésbé károsítják Földünket. A kutatók számára ma az jelent feladatot, hogy ezen erőforrások felhasználásának korlátait felkutassák, feltárják.

A memory like a female Fur Seal: long-lasting recognition of pup's voice by mothers
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Mathevon,Nicolas; Charrier,Isabelle; Aubin,Thierry.
In colonial mammals like fur seals, mutual vocal recognition between mothers and their pup is of primary importance for breeding success. Females alternate feeding sea-trips with suckling periods on land, and when coming back from the ocean, they have to vocally find their offspring among numerous similar-looking pups. Young fur seals emit a 'mother-attraction call' that presents individual characteristics. In this paper, we review the perceptual process of pup's call recognition by Subantarctic Fur Seal Arctocephalus tropicalis mothers. To identify their progeny, females rely on the frequency modulation pattern and spectral features of this call. As the acoustic characteristics of a pup's call change throughout the lactation period due to the growing...

Scientific discoveries rely on creative thinking, and several authors have explored similarities in and differences between creativity in the sciences and that in the arts. Here we explore possible ways in which science can learn from the arts, focusing specifically on experiences derived from the art of magic and on the limitations of human cognition. Generations of stage magicians or &amp;#8220;illusionists&amp;#8221; have made sophisticated use of the weaknesses in human systems of perception and interpretation. We highlight three important principles of magic tricks, including: (1) the audience see what it expects, (2) it is blind to all but the focus of attention, and (3) ideas spring predictably from a primed mind.

Abstract We aimed to analyze the correlation between ABCG2 gene polymorphisms of 34 GG/(GA + AA) loci, 421 CC/(AC + AA) loci, and non-small cell lung cancer (NSCLC) therapeutic effects via meta-analysis. With key words, the databases PubMed and EMBASE were searched for clinical studies on ABCG2 polymorphism and NSCLC. RR and 95% CIs were used to compute combined effects, followed by heterogeneity testing. Publication bias was examined using the funnel plot method. Review Manager 5.3 software was used for the meta-analysis. Ten studies were included. No evidence of heterogeneity exists in these studies. The results indicate that two polymorphic loci of ABCG2 gene (34 G&gt;A, and 421 C&gt;A) had no relationship with the curative effect of chemotherapy for...

The study was carried out to develop and to evaluate new equations to predict dry matter intake (DMI) of Nellore and Zebu-crosses cattle using meta-analysis procedure. The data used to estimate the parameters were collected from independent performance experiments using growing and fattening Nellore and Zebu-crosses cattle, and they were compiled from 561 experimental units. Before proposing an equation to predict DMI, it was observed that the genetic group was a source of statisticaly significant variation. Therefore, equations to predict dry matter intake in the Zebu-Crosses and Nellore cattle were independently developed. The regression equations for Zebu-crosses cattle were: DMI = -2.6098 + 0.08844BW0.75 + 4.4672ADG - 1.3579ADG2 and DMI = -1.0094 +...

A meta-analysis of probiotics for preventing necrotizing enterocolitis in preterm neonates
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Yang,Y.; Guo,Y.; Kan,Q.; Zhou,X.G.; Zhou,X.Y.; Li,Y.
Necrotizing enterocolitis (NEC) is one of the most common acquired diseases of the gastrointestinal tract in preterm infants. Some randomized, controlled trials (RCTs) have indicated that probiotics may potentially lower the incidence of NEC and mortality. However, debate still remains about the safety of probiotics and their influence on normal infant growth. We performed this meta-analysis to assess the safety and benefits of probiotic supplementation in preterm infants. We searched in PubMed, Embase, and Cochrane databases for English references, and in Wanfang, VIP, and CNKI databases for Chinese references. Ultimately, 27 RCTs (including 9 Chinese articles) were incorporated into this meta-analysis. Relative risk (RR) and weighted mean difference...

A Metafrontier Analysis of Technical Efficiency of Selected European Agricultures
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barnes,   Andrew Peter; Revoredo-Giha,   Cesar.
Technical efficiency refers to the situation where it is impossible for a firm to produce, with the given know-how, (1) a larger output from the same inputs or (2) the same output with less of one or more inputs without increasing the amount of other inputs. In practice, the interest is on the relative position in terms of efficiency of a particular firm with respect to others. Therefore, technical efficiency is characterised by the relationship between observed production and some ideal or potential production (Greene, 1993). Although the beginning of the efficiency work can be traced to the 1950s (Farrell, 1957), there have been a growing interest on its use in benchmarking performance, predominantly as a means of identifying best practice and improving...

A Method for Detection of Trace Concentrations of Underivatized Amino Acid in Hydrothermal Fluids by Ion-Pairing Reversed-Phase UPLC-ESI-QTOF-MS
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Konn, Cecile; Magner, Jörgen; Charlou, Jean-luc; Holm, Nils G; Alsberg, Tomas.
Investigation of amino acids in hydrothermal systems is of prime importance for the understanding of geochemistry and microbiology of hydrothermal vents and plumes, for carbon and metals global cycles, for metabolism of some hydrothermal microorganisms and for the origin of life issue. Extensive theoretical and experimental work on amino acids behaviour in hydrothermal fluids has been done, conversely only few data exist on natural samples. Because each hydrothermal vent is unique, the more data we collect the better we will be able to address each of these questions. Usually amino acids in hydrothermal fluids have been measured by HPLC-FLD. The chromatographic separation was at least 26 min and up to 135 min and the required derivatization step may be...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cassar, Nicolas; Tang, Weiyi; Gabathuler, Hans; Huang, Kuan.
Because of the difficulty in resolving the large variability of N2 fixation with current methods which rely on discrete sampling, the development of new methods for high resolution measurements is highly desirable. We present a new method for high-frequency measurements of aquatic N2 fixation by continuous flow-through incubations and spectral monitoring of the acetylene (C2H2, a substrate analog for N2) reduction to ethylene (C2H4). In this method, named “Flow-through incubation Acetylene Reduction Assays by Cavity ring-down laser Absorption Spectros-copy” (FARACAS), dissolved C2H2 is continuously admixed with seawater upstream of a continuous-flow stirred-tank reactor (CFSR) in which C2H2 reduction takes place. Downstream of the flow-through incubator,...

A method for multiple sequential analyses of macrophage functions using a small single cell sample
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Nascimento,F.R.F.; Rodríguez,D.; Gomes,E.; Fernvik,E.C.; Russo,M.
Microbial pathogens such as bacillus Calmette-Guérin (BCG) induce the activation of macrophages. Activated macrophages can be characterized by the increased production of reactive oxygen and nitrogen metabolites, generated via NADPH oxidase and inducible nitric oxide synthase, respectively, and by the increased expression of major histocompatibility complex class II molecules (MHC II). Multiple microassays have been developed to measure these parameters. Usually each assay requires 2-5 x 10(5) cells per well. In some experimental conditions the number of cells is the limiting factor for the phenotypic characterization of macrophages. Here we describe a method whereby this limitation can be circumvented. Using a single 96-well microassay and a very small...

A method for the determination of two Alternaria toxins, alternariol and alternariol monomethyl ether, in tomato products
Provedor de dados: Brazilian Journal of Microbiology
Autores: Motta,Silvana da; Soares,Lucia M. Valente.
Tomatoes, as any soft skinned fruit, are easily susceptible to fungal rot. Alternaria is the genus most frequently encountered in tomatoes. A. alternata and other spp. have been shown to produce the toxins alternariol monomethyl ether (AME) and alternariol (AOH) in tomatoes. A method for determining AME and AOH in tomato products was developed and evaluated. The method involves extraction with methanol, clarification with ammonium sulfate, and partition to chloroform. Quantification was conducted by high performance liquid chromatography with diode array detector (DAD). Average recoveries were 98.7% and 84.1% for AME and AOH, respectively. The quantification limits of the method, defined as the minimum amount that allowed quantification and confirmation by...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fourquez, Marion; Obernosterer, Ingrid; Blain, Stephane.
Heterotrophic bacteria are key players in the biogeochemical cycle of iron (Fe) in the ocean, but the capability of different bacterial groups to access this micronutrient is ignored thus far. The aim of our study was to develop a protocol for the combined application of microautoradiography (MICRO) and catalyzed reporter depositionfluorescence in situ hybridization (CARD-FISH) using the radioisotope 55Fe. Among the different washing solutions tested, Ti-citrate-EDTA was the most efficient for the removal of extracellular 55Fe providing sufficiently low background values. We further demonstrate that the washing of cells with Ti-citrate-EDTA and the fixation with paraformaldehyde or formaldehyde do not induce leakage of intracellular 55Fe. Incubating...

Autores: Kapfer,   Martin; Kantelhardt,   Jochen.
The aim of land consolidation projects is to improve the competitiveness of agriculture. Since land consolidation is subsidised by national and European means, the effectiveness of such measures must be determined. The following paper presents a method which makes it possible to calculate the direct economic effects of land consolidation. The calculations, considering labour demand, machinery costs and headland effects, compare the economic situation before and after land consolidation. The method was applied to four land consolidation projects in Bavaria. It can be shown that, to a varying degree, land consolidation in the studied areas leads to a substantial decrease in labour demand and machinery costs.

A method to estimate the biomass of Spirulina platensis cultivated on a solid medium
Provedor de dados: Brazilian Journal of Microbiology
Autores: Pelizer,Lúcia Helena; Moraes,Iracema de Oliveira.
This paper presents a method to estimate the biomass of Spirulina cultivated on solid medium with sugarcane bagasse as a support, in view of the difficulty in determining biomass concentrations in bioprocesses, particularly those conducted in semi-solid or solid media. The genus Spirulina of the family Oscillatoriaceae comprises the group of multicellular filamentous cyanobacteria (blue-green microalgae). Spirulina is used as fish feed in aquaculture, as a food supplement, a source of vitamins, pigments, antioxidants and fatty acids. Therefore, its growth parameters are extremely important in studies of the development and optimization of bioprocesses. For studies of biomass growth, Spirulina platensis was cultured on solid medium using sugarcane bagasse...

Autores: De Donato,M.; Brenneman,R.A.; Stelly,D.M.; Womack,J.E.; Taylor,J.F.
A bovine 5,000 rad WG-RH panel was used to construct an RH map of bovine chromosome 5 (BTA5). Twenty-one microsatellites and thirteen genes were scored in the panel using PAGE and radioactive labeling. Marker retention ranged from 8.9%-25.8% and averaged 17.8%. Pairwise locus analysis placed all markers in a single syntenic group with a LOD support of 4.0. At a LOD support of 8.0, a centromeric group of 23 syntenic markers was formed. Telomeric groups of 11 and 9 markers were assembled with a LOD support of 6.0 and 8.0, respectively. All markers were ordered by maximum likelihood methods using the program RHMAP. Only 13 markers were ordered with a LOD support of at least 3.0, while 25 and 29 markers were ordered with a support of at least 2.0 and 1.0,...

A METHODOLOGICAL BASIS FOR THE EVALUATION OF MARKETING LOSSES OF FOODS IN DEVELOPING COUNTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Silva,   Carlos Arthur Barbosa da.
The shortage of food for a substantial proportion of the world's population is a problem which has been challenging our society for a long time.  In the 1972-1974 period an estimated 1.3 billion people subsisted in less developed countries with dietary energy supplies under the minimum nutritional requirements, and the current outlook is for a widening gap between needs and food supplies.  Although progress has been made in production oriented research, such as the development of high yielding crop varieties and of better way to control pests and diseases, there is still a need for additional means to increase the world food supply.  The objectives of this paper are as follows: 1) to define the problems and its relevance for developing countries; 2) to...

A methodological framework for analysing landscape dynamics in relation to organic farming
Provedor de dados: Organic Eprints
Autores: Levin, Gregor.
Since the mid-1980’ies Danish agriculture has been subject to a growing conversion into organic farming. Today roughly 6% of the cultivated land is farmed organically. Consequently, organic farming has a growing impact on the Danish agricultural landscape.  It is generally expected that conversion to organic farming leads to landscapes with a rich and diverse nature. However, for organic farming in Denmark there exist no specific rules or guidelines concerning conservation and/or improvement of nature values at landscape scale. A positive effect of organic farming techniques on nature content within cultivated fields is relatively well documented. Yet, information about the relation between organic farming and nature values outside or surrounding...

Despite the large number of species distribution modelling (SDM) applications driven by tracking data, individual information is most of the time neglected and traditional SDM approaches commonly focus on predicting the potential distribution at the species or population‐level. By running classical SDMs (population approach) with mixed models including a random factor to account for the variability attributable to individual (individual approach), we propose an innovative five‐steps framework to predict the potential and individual‐level distributions of mobile species using GPS data collected from green turtles. Pseudo‐absences were randomly generated following an environmentally‐stratified procedure. A negative exponential dispersal kernel was...

For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and...

A methodology for definition of rural spaces: an implementation in Brazil
Provedor de dados: Ciência Rural
Autores: Braga,Gustavo Bastos; Remoaldo,Paula Cristina; Fiúza,Ana Louise de Carvalho.
ABSTRACT: Rural spaces definitions are differentiated in several countries. The Organization for Economic Co-operation and Development (OECD) has standardized a rural definition by regional typology. The OECD regional typology set areas as Predominantly Urban, Intermediate, or Predominantly Rural. This paper analyses the application of OECD regional typology in Brazilian territory. The research used the OECD methodology, with support of GIS software, to define the rural areas in Brazil. The mostly segmented data from Brazilian Census of 2010 are used in contrast to others studies. The paper concludes that Brazil is more urban than official estimates and OECD reports. According to paper results, 87.48% of Brazilian population is urban and only one...

The growth in agricultural productivity and significance of science and technology in contributing to this growth has been well documented by Bredahl, Cline, Evenson (1967), Griliches (1964), and Peterson. The results of these studies generally indicate that over the past several decades, investment in agricultural research has paid off with relatively high rates of return. Most of this previous work, however, has been directed at estimating returns to aggregate agricultural research in an ex post sense at the national level and does not address the question of potential future returns to research at a state or regional level (Norton). Thus, a particular need exists to develop a methodology for evaluating the potential returns to specific types of...

An assessment of the reared stocks of the Pacific oyster (Crassostrea gigas ) has been recently conducted on the major French areas of molluscs culture. The methodology proposed included both estimates of densities obtained by subsampling in the field, and aerial photographs which covered the cultivated, intertidal area. The size and the number of samples were designed to reach a precision of 10% on the final assessment in each area. The field work consisted in weighing and counting the oyster in unit areas of 0.5 m2 for the bottom culture or in trays or bags, for the off bottom technique. These results give a better knowledge of the technique evolution and of the general structures in the cultivated areas.

Hazánk Európai Uniós csatlakozása után várható, hogy a kedvezőtlen adott-ságú mezőgazdaságilag művelt területek jelentős része kikerül a mezőgazdasági művelésből. Ezek a földterületek apróvad-gazdálkodás céljaira rendkívül jól hasznosíthatók. Ezeknek a létrehozásához ki kell dolgozni a megfelelő támogatási rendszert. (Az eddig ismert programok között a vadgazdálkodás csupán csak széljegyzetként szerepelt.) A vadgazdálkodási alap élőhely-fejlesztési támogatásait hosszú távra célszerű megtervezni.

A számítások rendkívül pozitív képet mutatnak a mezőgazdaság jövedelme-zőségéről 2004-ben, az újonnan csatlakozó országok mindegyikében. A jövede-lemnövekedés hátterében egyrészt a nagyobb átlaghozamok állnak – melyek a rendkívül kedvező időjárási feltételeknek köszönhetők –, másrészt az előző évihez képest mintegy 73%-kal megemelkedett uniós támogatások. - Calculations present an extremely positive picture of agricultural profitability in 2004 in each of the new accession states. In the background to income growth lies greater average yields on the one hand – the result of exceptionally favourable weather conditions – and on the other, the ca. 73% increase in EU subsidies in comparison to the previous year.

A köznyelvben üzemnek nevezik azt a helyet, épületet, melyben valamilyen gazdasági egység tevékenykedik, illetve valamilyen termelő tevékenységet folytatnak. Az EU tanácsi és bizottsági jogrendszere viszont az üzemet az üzemtulajdonosok által igazgatott termelőegységként definiálja. Az angolszász országokban a farm elnevezést használják, amely bármilyen típusú mezőgazdasági üzem, vállalat lehet (family farm: családi gazdaság, cooperative farm: mezőgazdasági szövetkezet, large-scale farm: nagyüzem, small-scale farm: kisüzem stb.). Véleményünk szerint az üzem fogalma alatt magát a gazdálkodó egységet célszerű érteni, függetlenül annak jogi formájától, méretétől.

Methylation of mercury (Hg) is the crucial process that controls Hg biomagnification along the aquatic food chains. Aquatic sediments are of particular interest because they constitute an essential reservoir where inorganic divalent Hg (HgII) is methylated. Methylmercury (MeHg) concentrations in sediments mainly result from the balance between methylation and demethylation reactions, two opposite natural processes primarily mediated by aquatic microorganisms. Thus, Hg availability and the activity of methylating microbial communities control the MeHg abundance in sediments. Consistently, some studies have reported a significant positive correlation between MeHg and HgII or total Hg (HgT), taken as a proxy for HgII, in aquatic sediments using...

The European clam, Ruditapes decussatus is a species with a high commercial importance in Portugal and other Southern European countries. Its production is almost exclusively based on natural recruitment, which is subject to high annual fluctuations. Increased knowledge of the natural reproductive cycle of R. decussatus and its molecular mechanisms would be particularly important in providing new highly valuable genomic information for better understanding the regulation of reproduction in this economically important aquaculture species. In this study, the transcriptomic bases of R. decussatus reproduction have been analysed using a custom oligonucleotide microarray representing 51,678 assembled contigs.

Autores: Israr  Khan; Muhammad Shuaib; Sikandar Khan; Muhammad Amir Zia; Haji Akbar.
Canola is important for its oil, anticarcinogenic phytochemicals and low saturated fat content and has wide scope for further improvement through genetic transformations. Micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of disease free progeny plants, using modern asceptic plant tissue culture methods and also to conserve germ plasm. A combination of auxin and cytikinin and a shock on growth regulator free medium is used for micropropagation. Molecular and physiochemical analysis done to know variation in seeds protein content and electric conductivity.

A mid-Holocene transition in the nitrogen dynamics of the western equatorial Pacific: Evidence of a deepening thermocline?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kienast, M.; Lehmann, M. F.; Timmermann, A.; Galbraith, E.; Bolliet, T.; Holboum, A.; Normandeau, C.; Laj, C.
Sedimentary delta(15)N records from the oligotrophic western equatorial Pacific (WEP) off Mindanao show that late Holocene sedimentary delta(15)N is substantially lower than that of the early Holocene, following a gradual &gt;3 parts per thousand decrease that occurred between 7 and 3 kyrs ago. Analyses of modem day nitrate isotope profiles from the same region indicate the sensitivity of the WEP N pools towards (1) the advection of (15)N-enriched nitrate from the Eastern Equatorial Pacific (EEP) by the North Equatorial Current (NEC) and the Mindanao Current in subsurface waters and, (2) at shallow depths, the input of new and (15)N-depleted nitrate through N, fixation. We suggest that the Holocene decrease in sedimentary delta(15)N reflects a diminished...

A MINŐSÉGMENEDZSMENT A HAZAI BAROMFI-FELDOLGOZÁSBAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mikaczo,   Andrea.
A vizsgálatok alapján megállapítható, hogy a magyar baromfi-feldolgozó iparág megfelelően teljesíti mind a hazai, mind az EU-s előírásokat, követelményeket. Az élelmiszerbiztonsági előírásoknak való megfelelés valamennyi érintett vállalkozásban elsődleges szempont. A magas minőségi színvonal elérésére és teljesítésére irányuló további módszereket, mint pl. az integrált menedzsment irányítási rendszereket is alkalmazzák a vállalkozások, de az ezekre való törekvést nem a vállalat belső igénye, hanem a piac indukálja. Remélhetőleg a jövőben egyre több élelmiszeripari vállalkozás ismeri fel az ISO 22000 szabvány alkalmazásának előnyeit, ami ötvözi a HACCP és az ISO 9001 alkalmazását, és kifejezetten az élelmiszeripari termelésre specializált szabványként...

A misrepresentation through a misleading diagnosis in Winberg’s Florula Javanica
Provedor de dados: Naturalis Digital Academic Repository
Autores: Vuijk, J.
Spiranthes sinensis (Pers.) Ames, also known under the synonym S. australis (R. Br.) Lindl., is a terrestrial orchid widely spread in Asia, which is rather well known in Western Europe, because it has repeatedly been found growing spontaneously in pots in orchidhouses. In Blumea 6(2): 361 (1950) the plant described as Ophrys lancea Thunb. ex Sw. was considered to be identical with the first and it was thought that the recombination Spiranthes lancea (Thunb. ex Sw.) B. B. S. was necessary. The reasons given for this transfer were: (1) the short diagnosis of Ophrys lancea given by Winberg in Florula Javanica, p. 8 (1825); (2) the original diagnosis of O. lancea in Swartz’s well-known dissertation on the classification of orchids in Kongl.

A Mixed Geographically Weighted Approach to Decoupling and Rural Development in the EU-15
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pecci,   Francesco; Sassi,   Maria.
The CAP reform and the recent EC communication aimed at preparing its Health Check emphasise the need for interventions locally based where agricultural policy integrates with a broader policy for rural areas growth. In this context, the paper investigates the possible different sets policy indicators affecting agricultural productivity at the regional level considering spatial heterogeneity by means of a Mixed Geographically Weighted Regression approach. The analysis is based on a set of policy sensitive indicators selected according to the key component of the CAP reform and referred to a sample of 164 EU-15 regions at NUTS2 level. The methodology adopted, new for the empirical literature on the topic, allows for a more accurate understanding of spatial...

A mixed-method approach for determining the risk and complexity farmers associate with using forward contracts
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jackson,   Elizabeth; Quaddus,   Mohammed; Islam,   Nazrul; Stanton,   John.
This paper reports on a model that was developed to understand the behavioural determinants surrounding farmers’ adoption of forward contracts for agricultural commodities.  Based on the Theory of Planned Behaviour and Diffusion of Innovations, 28 hypotheses within the model were written and then tested via a telephone survey that gathered 305 responses from Western Australian wool producers.  The data from the telephone survey were analysed using SPSS 14 and the Partial Least Squares approach to Structural Equation Modelling.  Most relationships within the model could be explained after rigorous quantitative analysis, however, further explanation was required to understand two final aspects of adoption behaviour: firstly, the sources of risk wool...

To address increasing conflicts between surface water and groundwater users, the state of Nebraska has adopted a more localized and integrated approach in managing water resources. Integrated approaches offer promise in better managing connected water resources within the state; however, little review of the potential benefits and/or challenges of these actions has been conducted. This case study uses both qualitative and quantitative data collection efforts to take an in-depth look at how this new and innovative management system is working through the eyes of stakeholders living and working in the basin. Data collection reveals that overall the current water management system is working relatively well, even though it is still in its infancy. However,...

Autores: MENDOZA,URSULA; CANDELLA,ROGÉRIO N.; ASSAD,LUIZ P.F.; CASTILLO,FEDERICO V.; AZEVEDO,LAURA; KNOPPERS,BASTIAAN A.; ALBUQUERQUE,ANA LUIZA S.
This work addresses the design and configuration of a Eulerian sediment trap mooring array, which was deployed at the shelf edge (zm ≈ 140 m) 80 km off Cabo Frio, SE- Brazil (23° S). The site was subject to interplay between the Tropical Waters (TW) of the Brazil Current (BC), intrusions from the South Atlantic Central Waters (SACW), which are the source of upwelling in the region, and other oceanographic processes. Detailed computations were used to optimize the total weight, buoyancy balance, and maximum acceptable tilt to avoid hydrodynamic bias in the trapping efficiency and array adaptation to the local oceanographic conditions with the assistance of Matlab and Muringa programs and Modular Ocean Model 4.0 (MOM; i.e., to assert the vertical...

A model based on data from echosounder buoys to estimate biomass of fish species associated with fish aggregating devices
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lopezi, Jon; Moreno, Gala; Boyra, Guillermo; Dagorn, Laurent.
Most of the drifting fish aggregating devices (DFADs) used in industrial tropical tuna purse seine fisheries are equipped with satellite linked echosounder buoys, which provide fishing crews with remote, accurate geolocation information and rough estimates of FAD-associated tuna biomass. One of the most common brands of echosounder buoys (SATLINK, Madrid, Spain) is currently calibrated for the target strength of skipjack tuna (Katsuwonus pelamis) and provides biomass data on. that species. Using that brand of echosounder buoy, we developed a new behavior-based approach to provide relative biomass estimates and a remote target classification of fish aggregations at FADs. The model is based on current knowledge of the vertical distribution of the main fish...

A model for eel growth in aquaculture
Provedor de dados: Open Marine Archive
Autores: Houvenaghel, T.; Huet, T.
Growth in eel populations is not centered around the mean. The model described here is designed to take the growth rate variability into account by classifying the population, step by step in time, into size boxes on which grading and grouping occurs. By selecting options, this model allows the fit to other growth conditions and therefore can be adapted to other species. This growth model is the backbone of a predictive model for aquaculture, built up by adding allometric functions related to basic physiological properties.

A model for predicting the quantities of dissolved inorganic nitrogen released in effluents from a sea bass (Dicentrarchus labrax) recirculating water system
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pagand, Pascal; Blancheton, Jean-paul; Casellas, Claude.
Fish excretions and the transformation of nitrogen by bacteria in the nitrifying biofilter are two of the main sources of dissolved inorganic nitrogen (DIN) in fish farms that use recirculating water systems. In this study, the DIN concentration in an experimental Dicentrarchus labrax aquaculture system was calculated using empirical sub-models for fish growth, ingested food and water replacement. The specific growth rate (SGR) (% day(-1)) and the daily feeding rate (DFR) (% day(-1)) both depend on the average weight, W (g), of the fish: Y = aW(b), where Y may be SGR or DFR, and a and b are empirical constants. The DIN discharge rate, Gamma(N) (% of ingested nitrogen), in the experimental aquaculture system was expressed as a function of increasing...

A model for prediction of spatial farm structure
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoveid,   Oyvind; Stokstad,   Grete.
Spatial micro structure and its change over time is recorded for Norwegian farm firms. Relative strong correlations between geographically close neighbors are expected, either because growing farms swallow the smaller ones, or because they are affected by some spatially related unobserved factors. Strong correlations over time are also expected because of prevalent family farming. The paper proposes a state-of-the-art Markov chain model in order to predict the spatial and temporal micro structure taking account of both non-stationarity and spatio/temporal correlations by means of techniques from non-linear state space modeling and Gaussian Markov random fields. The model and the complete data set is then a device with which one can investigate the...

A MODEL FOR THE ECONOMIC EVALUATION OF PLANTATION BIOMASS PRODUCTION FOR CO-FIRING WITH COAL IN ELECTRICITY PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nienow,   Sara; McNamara,   Kevin T.; Gillespie,   Andrew R.; Preckel,   Paul V.
Public and private electric utilities are considering co-firing biomass with coal as a strategy to reduce the levels of CO2, SO2 and NO, in stack emissions, as well as a response to state legislative mandates requiring the use of renewable fuels. This analysis examines the conditions under which biomass co-firing is economically feasible for utilities and woody biomass producers and describes additional environmental and community benefits associated with biomass use. This paper presents a case study of woody biomass production and co-firing at the Northern Indiana Public Service Company (NIPSCO) Michigan City Unit No.12 power plant. A Salix (willow) production budget was created to assess the feasibility of plantation tree production to supply biomass to...

A model for the importance of large arborescent palms in the dynamics of seasonally-dry amazonian forests
Provedor de dados: Biota Neotropica
Autores: Salm,Rodolfo; Jalles-Filho,Euphly; Schuck-Paim,Cynthia.
In this study we propose a model that represents the importance of large arborescent palms in the dynamics of seasonally-dry Amazonian forests. Specifically, the model is aimed at guiding the investigation of the role of large arborescent palms on forest regeneration and succession. Following disturbance, the high level of luminosity reaching recently formed forest gaps favors the quick proliferation of shade-intolerant lianas that, by casting shade on the crowns of mature forest trees and increasing tree-fall probability, suppress forest succession. Due to their columnar architecture palm trees are, however, not severely affected by vines. As the palms grow, the canopy at the gaps becomes gradually higher and denser, progressively obstructing the passage...

Autores: Fonseca,Marbella Maria; Alarcon,Frank J.B.; Vasconcelos,Ana Tereza de; Agnez-Lima,Lucymara Fassarela.
In this work, we predict a structural model for the RecA protein from M. synoviae (MsRecA) by theoretical homology modeling and evaluate the occurrence of polymorphisms in this protein within several isolates of this species. The structural model suggested for MsRecA conserves the main domains present in MtRecA and EcRecA. The L1 and L2 regions showed six and three amino acid substitutions, respectively, which apparently do not affect the conformation and function of MsRecA. The C-terminal domain is shorter than that found in EcRecA and MtRecA, which may increase its capacity to bind dsDNA and displace SSB, compensating the absence of recombination initiation enzymes. The MS59 isolate RecA sequence showed one polymorphism which does not affect its...

A model of early diagenetic processes from the shelf to abyssal depths
Provedor de dados: Open Marine Archive
Autores: Soetaert, K.; Herman, P.M.J.; Middelburg, J.J.
We present a numerical model of sedimentary early diagenetic processes that includes oxic and anoxic mineralization. The model belongs to the new wave of early diagenesis models that account for depth-dependent bioturbation and porosity profiles; it can be used both for calculating steady-state conditions and transient simulation. It was developed to reproduce the cycling of carbon, oxygen, and nitrogen along the ocean margin; it resolves the sediment-depth profiles of carbon, oxygen, nitrate, ammonium, and other reduced substances. Organic carbon is modeled as two degradable fractions with different first-order degradation rates and nitrogen:carbon ratios, to account for the decreasing reactivity and N/C ratio of the organic matter with depth into the...

A MODEL OF ENVIRONMENTAL COMPROMISE BETWEEN REGULATORS AND REGULATED PARTIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hsu,   Shi-Ling.
Environmental regulations implemented by administrative agencies have often been met with fierce political resistance from regulated parties.  In some instances, regulated parties have turned to legislative and judicial bodies for relief from environmental regulation.  As these political and legal battles have escalated, several forms of compromises have evolved.  The U.S. Fish and Wildlife Service, in its administration of the Endangered Species Act, has often utilized the tool of "Habitat Conservation Planning" as a means by which some regulatory relief is granted in exchange for an agreement by the regulated party to undertake mitigation measures to aid endangered or threatened species.  As a further inducement for regulated parties to enter into the...

A model of fluff layer erosion and subsequent bed erosion in the presence of the bioturbator, Hydrobia ulvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Orvain, Francis; Le Hir, Pierre; Sauriau, Pierre-guy.
Previous studies have shown that the gastropod Hydrobia ulvae destabilizes the top layers of fine-grained sediments. This process is mediated by the formation of a "biogenic" fluff layer that includes tracks, faecal pellets and mucus. This fluff layer has been shown to be easily resuspended before general bed erosion. In order to examine how fluff layer and bed. erosion interact, flume experiments were performed with fluid sediments of varying water contents. Ten thousand snails were placed and allowed to crawl for 5 h on the sediment surface, and then the resuspended sediment mass was measured in response to step-wise shear stress increases. Two distinct erosion phases were observed: (1) initial resuspension of the fluff layer and (2) the subsequent bed...

Acrolein is a urinary metabolite of cyclophosphamide and ifosfamide, which has been reported to be the causative agent of hemorrhagic cystitis induced by these compounds. A direct cytotoxic effect of acrolein, however, has not yet been demonstrated. In the present study, the effects of intravesical injection of acrolein and mesna, the classical acrolein chemical inhibitor, were evaluated. Male Swiss mice weighing 25 to 35 g (N = 6 per group) received saline or acrolein (25, 75, 225 µg) intravesically 3, 6, 12, and 24 h before sacrifice for evaluation of bladder wet weight, macroscopic and histopathological changes by Gray's criteria, and 3 and 24 h for assessment of increase in vascular permeability.

A MODEL OF MINIMUM SIZE LIMIT REGULATIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Homans,   Frances R.; Ruliffson,   Jane A.
Minimum size limits have become an increasingly popular management tool in recreational fisheries.  This popularity stems from the potential of minimum size limits to accomplish the twin goals of limiting overfishing and improving fishing quality through increasing the average size of fish caught.  The success of minimum size limits in achieving these objectives depends in a complicated way on both the behavior of anglers and the biological mechanisms that guide the growth of the fish population.  This paper examines these relationships and also considers the welfare implications of size regulations.

A model of nematode dynamics in the Westerschelde Estuary
Provedor de dados: Open Marine Archive
Autores: Li, J.; Vincx, M.; Herman, P.M.J.
We developed a time dynamic model to investigate the temporal dynamics of nematode community in the brackish zone of the Westerschelde Estuary. The biomass of four nematode feeding groups observed from March 1991 to February 1992 is used to calibrate the model. Using environmental data as the input, the model predicts the temporal modification and interrelation of four nematode feeding groups. Nematodes achieve a dominant position in the community because of their lower loss rate (in respiration, excretion and natural death). Predators which are deposit-feeding macrobenthos control the variations of dominant nematodes, such as omnivores and non-selective deposit feeders. Food availability causes modification only for rare nematodes such as epigrowth...

A MODEL OF OPTIMAL PUBLIC INVESTMENT IN U.S. AGRICULTURAL RESEARCH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fox,   Glenn.
This paper examines three claims of inefficient allocation of public expenditure in publicly funded agricultural research in the United States.  It has been argued by analysts of research policy that: 1. The overall level of public investment in agricultural research is less than what would be socially optimal. 2. The present composition of public research investment is excessively myopic in that too little basic research is performed relative to the level of applied research. 3. The allocation of research resources among commodities is inconsistent with economic efficiency. A nonlinear optimal growth model of the U.S. economy was employed to test these propositions.  Strong support was found for the claim that the overall level of investment has been...

A model of sea-foam thickness distribution for passive microwave remote sensing applications
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Reul, Nicolas; Chapron, Bertrand.
[1] Foam formations at the sea surface significantly contribute to microwave brightness temperature signatures over the ocean for moderate to high wind speeds. The thickness of foam layers generated by breaking waves follows a specific distribution due to unsteadiness of breaking and the large range of wave scales involved in the phenomenon. Although the effect of a distributed thickness-parameter on the foam-induced microwave brightness temperature may be comparable to or larger than the fractional whitecap coverage, it is not yet included in brightness models. To fill this gap, we develop a dynamical model for the conditional fraction of sea-surface covered by whitecaps with given thickness, as a function of wind speed. It is an integrated function of...

A model of sediment transport under the influence of surface bioturbation: generalisation to the facultative suspension-feeder Scrobicularia plana
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Orvain, Francis.
Flume experiments were designed to study how sediment erodibility was modified by the facultative suspension-feeder Scrobicularia plana living at different densities in sediment beds of various degrees of compaction. Two separate erosion phases were identified from the resuspension kinetics: (1) erosion of an unconsolidated surficial layer (i.e. fluff layer) and (2) the subsequent bed erosion. S. plana were found to influence both erosion phases: (1) erosion rates of the fluff layer were controlled by bioturbation activities, the extents of which were influenced by bivalve density and the degree of compaction of the sediments, and (2) critical thresholds of the subsequent bed erosion decreased as clam density increased, likely due to depressions in the...

A MODEL OF THE IMPLEMENTATION OF QUALITY MANAGEMENT SYSTEMS FOR CREDENCE ATTRIBUTES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Noelke,   Corinna M.; Caswell,   Julie A.
We develop a model of the impact of food quality management systems (QMS) on competitiveness and markets.  QMS seek to control the quality of a product as determined by the array of individual attributes it possesses.  To date only a few studies have attempted to better understand the effect of the introduction of quality management systems.  No model has been introduced which captures the interactions within the supply chain and at the interface with consumers when these systems are introduced.

Ten crossbred barrows weighting 20kg were allocated in five groups fed and on diets consisted of different total phosphorus (P) levels: 0.30%, 0.40%, 0.51%, 0.65%, and 0.73%. The animals were intravenously injected 7.4MBq of radioactive P (32P) and after seven days they were slaughtered for further analysis. The evaluated parameters were intake, excretion, specific activities, and flow of P in compartments (1-gut, 2-blood, 3-bone, and 4-soft tissue). Besides fecal losses, the kidneys played an import role in P regulation. The flows of P from tissue and gut to the blood were affected by P intake.

A model simulation analyses of nitrate leaching – does soil organic matter pool structure or catch crop growth parameters matter most?
Provedor de dados: Organic Eprints
Autores: Pedersen, Anders; Petersen, Bjørn Molt; Eriksen, Jørgen; Hansen, Søren; Jensen, Lars Stoumann.
Modelling of soil organic matter (SOM) turnover has often been developed in order to or to predict crop fertilser demand or to analyse environmental impact of different agriculture management practices. Mechanistic simulation models can be used to predict the mineralization of nitrogen (N) in added organic matter, e.g. from animal manure or incorporated crop residues, and the timing of N availability to the succeeding crops. In this way, mechanistic models may be used to avoid excessive fertilisation and hence to minimise nitrate leaching. The objective of this work was therefore to analyse the consequences of applying different SOM and crop modules (differing in pool structure or parameterisation) in the soil-plant-atmosphere model Daisy on the simulated...

A model study of the seasonal and long-term North Atlantic surface pCO(2) variability
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Tjiputra, J. F.; Olsen, A.; Assmann, K.; Pfeil, Benjamin; Heinze, C.
A coupled biogeochemical-physical ocean model is used to study the seasonal and long-term variations of surface pCO(2) in the North Atlantic Ocean. The model agrees well with recent underway pCO(2) observations from the Surface Ocean CO2 Atlas (SOCAT) in various locations in the North Atlantic. Some of the distinct seasonal cycles observed in different parts of the North Atlantic are well reproduced by the model. In most regions except the subpolar domain, recent observed trends in pCO(2) and air-sea carbon fluxes are also simulated by the model. Over the longer period between 1960-2008, the primary mode of surface pCO(2) variability is dominated by the increasing trend associated with the invasion of anthropogenic CO2 into the ocean. We show that the...

A model to explain high values of pH in an alkali sodic soil
Provedor de dados: Scientia Agricola
Autores: Guerrero-Alves,José; Pla-Sentís,Ildefonso; Camacho,Rafael.
For alkali sodic soils (pH&gt;8.5), the "hydrolysis of exchangeable sodium" has been used as a possible explanation for the alkalinity production and rise in pH of these soils. As an alternative to this hypothesis, a model was developed to simulate and to explain that the alkalinity production and rise in pH is possible in a soil that accumulates alkaline sodium salts and CaCO3. Several simulations were performed by using different combinations of CO2 partial pressures (P), presence or absence of MgCO3, along with experimental values of exchangeable sodium percentage (ESP) and ion concentrations in saturation extracts from an alkali sodic soil (named Pantanal). A hypothetical system with similar conditions to the Pantanal soil but with a Gapon selectivity...

A MODEL TO EXPLAIN PARTICIPATION IN NEW YORK'S AGRICULTURAL DISTRICTS AND USE-VALUE ASSESSMENT PROGRAMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Boisvert,   Richard N.; Bills,   Nelson L.; Bailey,   Elizabeth.
Logit regression models are estimated to identify factors affecting decisions to enroll farmland in New York's agricultural districts program and participate in the use-value assessment program.  The results suggest that the districts law is consistent with preserving the best farmland at the rural-urban fringe and that the decision to enroll in agricultural districts affects in a recursive fashion the decision to participate in the use-value assessment program.  Short-term monetary gains are the overriding considerations in applying for use-value exemptions.  This may lead to additional erosion of the tax base via tax preferences for agricultural land.

A Modelling Approach for Evaluating Agri-Environmental Policies at Sector Level
Provedor de dados: Organic Eprints
Autores: Schader, C.; Sanders, J.; Nemecek, T; Lampkin, N. H.; Stolze, M.
This paper presents a new approach to evaluate the cost effectiveness of agri-environmental policies at sector level. Policy uptake, cumulative environmental effects and public expenditure are identified as the main determinants of cost-effectiveness. On the basis of the sector-consistent, comparative-static, farm group model FARMIS, the determinants of policy cost-effectiveness at sector level are addressed. Firstly, intensity levels for the FARMIS activities are defined in order to model uptake of agri-environmental policies with FARMIS, secondly, life-cycle assessment data is attached to these intensity levels to determine environmental effects of the policies and thirdly, public expenditure is calculated under consideration of transaction costs. This...

A modelling study of the respective role of hydrodynamic processes and larval mortality on larval dispersal and recruitment of benthic invertebrates: example of Pectinaria koreni (Annelida : Polychaeta) in the Bay of Seine (English Channel)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ellien, C; Thiebaut, E; Dumas, Franck; Salomon, Jean-claude; Nival, Paul.
The dispersal of Pectinaria koreni larvae released from the eastern Bay of Seine (English Channel) was studied using a two-dimensional hydrodynamic model which integrates tides, wind-driven currents and eddy diffusion, in order to examine the influence of environmental forcing and mortality on larval population dynamics. A broad agreement between predicted larval dispersal for two spawning events observed in 1987 and field data suggests that numerical modelling may be useful to analyse processes involved in the transport and the dynamics of larval populations. Larval mortality may be as important as hydrodynamic processes on larval losses for the adult population. Tides and eddy diffusion had some effects on larval dispersal, but wind forcing and the...

A moderate decrease in temperature inhibits the calcium signaling mechanism(s) of the regulatory volume decrease in chick embryo cardiomyocytes
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Souza,M.M.; Boyle,R.T.
Chick cardiomyocytes, when submitted to hyposmotic swelling, exhibit a partial regulatory volume decrease (RVD). A Ca2+ influx by stretch-activated channels signals a taurine efflux and the RVD at 37°C. We evaluated the cell's performance at room temperature. Cardiomyocytes isolated and cultured from 11-day-old chick embryos were submitted to a hyposmotic solution (180 mOsm/kg H2O) at 37°C and at room temperature (26°C). Under these conditions we measured the changes in cell volume as well as the intracellular free Ca2+ (using fura-2). During hyposmotic swelling, cells at 37°C displayed a peak relative volume of 1.61 ± 0.03 and recovery to 1.22 ± 0.04 (N = 14), while cells at 26°C presented a peak swell relative volume of 1.74 ± 0.06 and did not recover...

A moderate melting model for the Voring margin (Norway) based on structural observations and a thermo-kinematical modelling: Implication for the meaning of the lower crustal bodies
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gernigon, Laurent; Lucazeau, Francis; Brigaud, Frederic; Ringenbach, Jean-claude; Planke, Sverre; Le Gall, Bernard.
High P-wave velocities (7.1-7.8 km/s) lower crustal bodies (LCBs) imaged along volcanic margins are commonly interpreted as plume and break-up-related thick mafic underplating. This interpretation is partly challenged in this paper based on new seismic observations and modelling of the outer Voring Basin (Norway). An exceptional strong amplitude reflection, the T Reflection, is particularly well defined below the North Gjallar Ridge (NGR) between 7 and 8 s TWT. The T Reflection is located near the volcanic lava flows emplaced during the NE Atlantic breakup (similar to 55-54 Ma ago) and coincides with the top of the LCB, forming a mid-crustal dome. Based on structural and temporal relationships, we show that the dome clearly influences the structural...

A moderate threonine deficiency affects gene expression profile, paracellular permeability and glucose absorption capacity in the ileum of piglets
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hamard, Alice; Mazurais, David; Boudry, Gaelle; Le Huerou-luron, Isabelle; Seve, Bernard; Le Floc'H, Nathalie.
High dietary threonine extraction by the digestive tract suggests that threonine contributes to maintain gut physiology. In the present study, we evaluated the impact of a low (6.5 g of threonine/kg diet; LT group) or a control well-balanced threonine diet (9.3 g of threonine/kg diet; C group) given to piglets for 2 weeks on ileal permeability and Na+-dependant glucose absorption capacity in Ussing chambers. The paracellular permeability was significantly increased in the ileum of LT compared to C piglets (P=.017). The Na+-dependent glucose absorption capacity showed a nonsignificant increase in the LT piglets. In addition, we analysed ileal gene expression profiles in the LT and C groups using porcine multitissue cDNA microarrays. Compared to the C...

A Modified Environmental Kuznets Curve for Sustainable Development Assessment Using Panel Data
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Costantini,   Valeria; Martini,   Chiara.
Sustainable development is a concept strictly connected with basic needs of the individuals. During the last years a number of empirical studies have tried to discover and quantify the causal relations between economic growth and environmental consumption and degradation. The most widely used empirical model is the so-called Environmental Kuznets Curve (EKC), nowadays applied to different polluting elements. Despite the huge diffusion of EKC studies, this model has been criticised for incompleteness of a sustainable development analysis. The aim of this paper is to build a Modified EKC (MEKC) in order to consider a wider concept of development rather than pure economic growth, including well-being aspects and sustainability of the development process....

A Modified phosphate-carrier protein theory is proposed as a non-target site mechanism For glyphosate resistance in weeds
Provedor de dados: Planta Daninha
Autores: Roso,A.C.; Vidal,R.A.
Glyphosate is an herbicide that inhibits the enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPs) (EC 2.5.1.19). EPSPs is the sixth enzyme of the shikimate pathway, by which plants synthesize the aromatic amino acids phenylalanine, tyrosine, and tryptophan and many compounds used in secondary metabolism pathways. About fifteen years ago it was hypothesized that it was unlikely weeds would evolve resistance to this herbicide because of the limited degree of glyphosate metabolism observed in plants, the low resistance level attained to EPSPs gene overexpression, and because of the lower fitness in plants with an altered EPSPs enzyme. However, today 20 weed species have been described with glyphosate resistant biotypes that are found in all five...

A Molecular Perspective On The Diversification Of Short-Tailed Opossums (Monodelphis: Didelphidae)
Provedor de dados: Mastozoología Neotropical
Autores: Solari,Sergio.
As currently understood Monodelphis includes more than 22 species and is the most diverse genus of opossums (Didelphimorphia). No complete evaluation of the systematic relationships of its species has been attempted, despite the fact that several species groups and even genus-level groups have been proposed based on morphology, and that some of them are limited to recognized biogeographic regions. Here, genealogic relationships among 17 species were assessed based on phylogenetic analyses of 60 individual sequences (801 base pairs of the mitochondrial cytochrome b gene). The analyses cast doubts on the monophyly of Monodelphis, but species were consistently discriminated into eight species groups: (a) brevicaudata group, with five species, (b) adusta...

Autores: Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W.
The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I &amp; II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

A monograph of the fern genus Bolbitis (Lomariopsidaceae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hennipman, E.
The present study deals with systematic and taxonomic problems in the acrostichoid fern genus Bolbitis (Lomariopsidaceae). The idea came from Prof. Holttum, Kew, in view of his intended revision of the lomariopsidoid ferns for Flora Malesiana. Originally the study was confined to the Asian representatives. However, various problems remained unsolved after the study of these taxa alone, and it was decided to monograph the genus. The taxonomy of the genus Bolbitis was seriously misunderstood in the past—parallel evolution obscuring true relationships—and a rather intricate synonymy has resulted. A brief historical sketch of its taxonomic adventures is worked out. The gross-morphological criteria used for the discrimination of the species by Copeland (who...

The Phylactolaemata are to be considered as a group that have completed their evolution with the development of giant species with giant and specialized forms of statoblasts; this has been accompanied by a reduction in the number of tentacles. 4. The distribution of the species was assessed from the available data. The main concentration is found to occur in the southern hemisphere. 5. The distribution supports the conclusion that...

We find the interpretation of the genus Aristida by BEAUVOIS in his work Essai d’une nouvelle Agrostographie on pag. 33. Aristida lanata is the only species mentioned by him and the genus is figured on Pl. VIII. fig. X. This figure is a rather rough sketch and represents Aristida ciliata DESF.. In the figures b and c there is a well-developed column and the central awn is plumose, the articulation between lemma and column is omitted or overlooked. Aristida lanata, as mentioned by BEAUVOIS, is quite different from the A. lanata, described by FORSKÅL, where all the awns are plumose and the glumes are quite different.

Autores: Payens, J.P.D.W.
A brief history is given on the circumscription and subdivision of Lecythidaceae and the position of Barringtonia. All aspects, also of auxiliary disciplines point to affinity with Myrtaceae but warrant separate family status. The conviction is that only one family is concerned, not two, or even three, as Knuth proposed. The subdivision of Lecythidaceae appears to meet with great difficulty. It does not seem to be possible to divide the family in tribes which would be restricted to the New and Old Worlds respectively, affinities running transoceanic. In the present revision of the genus Barringtonia 39 species are distinguished, 3 of which have one or a few new subspecies, varieties, or forms; three species are newly described.

Autores: Jentink, F.A.
A rare constancy in color of the fur in some species, a nearly endless variety in other species and a very peculiar geographical distribution render the study of this beautiful group of Marsupials very difficult but at the same time highly interesting and attractive. A thourough study based upon large and well selected series from the most different and distant localities is the only way to surmount the very difficulties. No wonder therefore that so many naturalists have failed in their efforts to recognize and circumscribe the species composing this group. The Cuscus-species have half or more than half the prehensile tail destitute of hair and the second and third toes of the hind feet united in a common integument very nearly to the extremity.

Autores: Bremekamp, C.E.B.
The name Pleiocarpidia was coined by K. SCHUMANN (ENGLER und PRANTL, Natürliche Pflanzenfamilien, Nachträge I, p. 314, 1897) for a genus described in 1873 by HOOKER f.

A proposal made by O.

A morphometric analysis of Eunice Cuvier (Annelida, Polychaeta) species
Provedor de dados: Zoologia
Autores: Costa-Paiva,Elisa M.; Paiva,Paulo C.
Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E.fucata, E.insularis, E. cf. ornata, E.rubra, and Eunice sp. was compared using traditional morphometric analysis of 16 measured variables. After removing the size-effect, a Canonical Variates Analysis applied to morphometric variables was able to discriminate all species. In CV1 two major groups of species were discriminated: E.fucata/E.insularis and E. cf. ornata/E.rubra/Eunice sp. CV2 strongly discriminated all species, with E....

Provedor de dados: Electronic Journal of Biotechnology
Autores: Revelo Romo,Dolly Margot; Grosso,María Victoria; Moreno Solano,Nubia Carmenza; Montoya Castaño,Dolly.
A molecular approach was used for selecting polyhydroxyalcanoate (PHA)-accumulating potential Gram-negative bacteria from different genera by colony polymerase chain reaction (PCR). Three degenerate primers were designed for amplifying a fragment from PHA synthase gene (phaC) (Class I), phaC1 and phaC2 (Class II) genes for detecting PHA-producing bacteria. Thirty-four out of 55 bacterial strains from the old collection selected using Sudan black B staining were phaC+. PCR was used for directly selecting 35 new collection bacterial strains; these strains were phaC+ and their ability to produce PHA was confirmed by Sudan black B staining. Four specific primers were designed on genes of Class II PHA biosynthesis operon. These primers were used for evaluating...

Autores: Dupuy, Celie; Couillard, Catherine M.; Laroche, Jean; Nellis, Pierre; Brousseau, Pauline; Fournier, Michel.
A multibiomarker approach was developed on juvenile Atlantic tomcod (Microgadus tomcod) to evaluate the pertinence of this approach for low-cost screening assessment of the environmental quality of various coastal sites within estuaries. Several biometric indices and biomarkers (ethoxyresorufin-O-deethylase (EROD) activity, metallothionein concentration, and immune responses) were investigated on immature and maturing tomcods (a parts per thousand currency sign31 months) collected in four environmentally contrasted sites in the St. Lawrence Estuary (SLE). Simultaneous examination of various age classes provides the opportunity to detect short-term responses in sensitive young-of-the-year fish (e.g., EROD induction) and longer-time effects associated with...

Australian wool producers have been slow to adopt price risk management strategies to stabilise the income from their wool sales.  The highly volatile auction system accounts for 85% of raw wool sales while the remainder is sold by forward contract, futures and other hedging methods.  Qualitative analysis was used to find behavioural factors associated with the adoption of price risk management strategies (specifically futures and forward contracts) for selling raw wool.  Consideration was given to Diffusion of Innovations and the Theory of Planned Behaviour as theoretical frameworks in order to answer the research question: Are there any non-traditional behavioural factors that need to be incorporated into existing frameworks to determine adoption of...

A multidisciplinary approach to improve the quality of organic wheat-bread chain
Provedor de dados: Organic Eprints
Autores: Abecassis, Joël; David, Christophe; Fontaine, Laurence; Taupier-Létage, Bruno; Viaux, P.
The main challenge for organic farmers, millers and bakers is to fulfill consumers’ expectations of providing healthy and safe products. The quality of organic grain can be modulated by agronomic modifications on genotypes, crop management, crop rotation and soil fertility, but the milling process and finally the baking process are also key factors in producing bread of high baking quality, nutritional value, taste and flavour. Nitrogen (N) is a key nutrient in achieving acceptable yield levels of sufficient bread-making quality, but previous results have shown that organic wheat tends to have lower protein content, dough mixing tolerance and loaf volume. The selection of genotypes with high N use efficiency, weed competitiveness and disease resistance...

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parra-Lopez,   Carlos; Calatrava-Requena,   Javier.
Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

Infrageneric relations of the genetically diverse milkcap genus Lactifluus (Russulales, Basidiomycota) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision. For this study, we assembled an extensive dataset of the genus Lactifluus, comprising 80 % of all known species and 30 % of the type collections. To unravel the infrageneric relationships within this genus, we combined a multi-gene molecular phylogeny, based on nuclear ITS, LSU, RPB2 and RPB1, with a morphological study, focussing on five important...

Sustainability theory can help achieve desirable social-ecological states by generalizing lessons across contexts and improving the design of sustainability interventions. To accomplish these goals, we argue that theory in sustainability science must (1) explain the emergence and persistence of social-ecological states, (2) account for endogenous cultural change, (3) incorporate cooperation dynamics, and (4) address the complexities of multilevel social-ecological interactions. We suggest that cultural evolutionary theory broadly, and cultural multilevel selection in particular, can improve on these fronts. We outline a multilevel evolutionary framework for describing social-ecological change and detail how multilevel cooperative dynamics can determine...

This study examines the effects of increasing salinity on fish assemblage structure in the Casamance Estuary, Senegal. using a series of indices. The study data were derived from commercial fishery surveys conducted between April and July 2005. Analysis of within-trophic-group diversity in the Casamance Estuary shows a significant drop in the diversity of apex predators in the upper. more saline reaches of the estuary. By contrast. primary consumers adapted well to salinity changes and exhibited higher taxonomic diversity in the upper reaches of the estuary than in the lower reaches. The findings also indicate decreases in average sizes of the landed species and the trophic levels among fish catches in the direction of the upper reaches. However, the catch...

A multi-model assessment of the impact of currents, waves and wind in modelling surface drifters and oil spill

Validation of oil spill forecasting systems suffers from a lack of data due to the scarcity of oil slick in-situ and satellite observations. Drifters (surface drifting buoys) are often considered as proxy for oil spill to overcome this problem. However, they can have different designs and consequently behave in a different way at sea, making it not straightforward to use them for oil spill model validation purposes and to account for surface currents, waves and wind when modelling them. Stemming from the need to validate the MEDESS4MS (Mediterranean Decision Support System for Marine Safety) multi-model oil spill prediction system, which allows access to several ocean, wave and meteorological operational model forecasts, an exercise at sea was carried out...

A Multiparametric Nonlinear Regression Approach for the Estimation of Global Surface Ocean pCO(2) Using Satellite Oceanographic Data
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Krishna, Kande Vamsi; Shanmugam, Palanisamy; Nagamani, Pullaiahgari Venkata.
Estimation of the partial pressure of carbon dioxide (pCO(2)) and its space-time variability in global surface ocean waters is essential for understanding the carbon cycle and predicting the future atmospheric CO2 concentration. Until recently, only basin-scale distribution of pCO(2) has been reported by using satellite-derived climatological data due to the lack of models for global-scale applications. In the present work, a multiparametric nonlinear regression (MPNR) for the estimation of global-scale distribution of pCO(2) on the ocean surface is developed using continuous in-situ measurements of pCO(2), chlorophyll-a (Chla) concentration, sea surface temperature (SST), and sea surface salinity (SSS) obtained on a number of cruise programs in various...

Michigan ranks among the top five asparagus producing states in the United States; ranking forth in production, and second in its seasonal group.  As of 1970, the five leading states in asparagus were: (1) California, (2) New Jersey, (3) Washington, (4) Michigan, and (5) Illinois.  Although the total acreages employed for asparagus production has been decreasing -3,800 acres between 1969 and 1970 -Michigan's has been increasing - 900 acres for the same period.  The marked decrease in asparagus production over the past decade may be explained by strong foreign competition, especially from Taiwan since 1964; and from competing enterprises in certain areas and from asparagus farms sharing in the natural attrition of all farms in the U.S.  The objective of...

Autores: Fraga,Aline Padilha; Vargas,Tatiana de; Ikuta,Nilo; Fonseca,André Salvador Kazantzi; Celmer,Álvaro José; Marques,Edmundo Kanan; Lunge,Vagner Ricardo.
Mycoplasma gallisepticum (MS) and Mycoplasma synoviae (MS) are important avian pathogens and cause economic losses to the poultry industry. Molecular biology techniques are currently used for a rapid detection of these pathogens and the adoption of control measures of the diseases. The aim of this study was to develop and validate a technique for simultaneous detection of MG and MS by multiplex real time polymerase chain reaction (PCR). The complete assay (Multiplex MGMS) was designed with primers and probes specific for each pathogen and developed to be carried out in a single tube reaction. Vaccines, MG and MS isolates and DNA from other Mycoplasma species were used for the development and validation of the method. Further, 78 pooled clinical samples...

A MULTI-SECTOR EXPORT BASE MODEL OF LONG-RUN REGIONAL EMPLOYMENT GROWTH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lego,   Brian; Gebremedhin,   Tesfa G.; Cushing,   Brian.
The relationships between intersectoral export and local employment and regional economic growth are analyzed in a long-run equilibrium framework. Dynamic location quotients decompose regional employment into export and local components for multiple sectors. Johansen's Full-Information Maximum Likelihood (FIML) approach is used to identify the existence and resultant rank of the co-integrating relationship between sectoral export and local employment in West Virginia's four metropolitan areas. Empirical results indicate inter-sectoral basic and non-basic employment form a co-integrating system of equations. Furthermore, this analysis shows that inter-sector shocks to local and export employment may cause multipliers to be positive or negative in magnitude.

A MULTIVARIATE ANALYSIS OF Boophilus microplus (ACARI: IXODIDAE): NON-PARASITIC PHASE
Provedor de dados: Revista de Salud Animal
Autores: de la Vega,R; Díaz,G; da Fonseca,A.H.
Multivariate statistical methods are relatively new tools for data analysis. They have a lot of applications in biological researches: nevertheless, for several reasons, they have not been widely employed in this subject yet. Recently, present authors published a paper applying multivariate statistics on non-parasitic phase of Anocentor nitens. In the present article Boophilus microplus has received a very similar statistic treatment. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 27, 30, 32, 34 and 36ºC and four relative humidity values, 100, 80, 75.5 and 70% over the cycle variables of B. microplus. According to the results, the best...

A multivariate analysis of taxonomic limits in Diplolaemus Bell 1843
Provedor de dados: Gayana
Autores: Victoriano,Pedro F; Coronado,Tanía M; Ortiz,Juan Carlos.
The gemís Diplolaemus Bell, 1843 is a common squamate component of the Patagonian región of South América. Considerable taxonomic confusión exists within this gemís, particularly about the status of Chilean-Andean populations and the actual distribution of D. leopardinas (Werner, 1898). In an attempt to clarify the taxonomic status and distribution of Diplolaemus species, we performed a principal component analysis (PCA) and discriminant function analysis (DFA) using both standard morphometric and meristic data. Multivariate summaries of morphometric data show that most species are poorly discriminated, with the exception of D. darwinii. In contrast, a PCA analyses performed on the meristic data clearly distinguish three discrete groups: 1. D. darwinii, 2....

A multivariate approach to explore the genetic variability in the F2 segregating population of a tomato second cycle hybrid
Provedor de dados: Journal of Basic and Applied Genetics (BAG)
Autores: Cabodevila,V.G; Picardi,L.A; Pratta,G.R.
Segregating progeny from the tomato Second Cycle Hybrids (SCH) that were obtained from crossing RIL (Recombinant Inbred Lines) allows the detection of new genetic combinations that could increase genetic variability in F2 populations. The objectives of the present study were to evaluate eleven tomato quality traits in a segregating F2 population obtained from a SCH and, then, to characterize the molecular diversity by six AFLP (Amplified Fragment Length Polymorphism) primer combinations. Different multivariate analyses were used to assess the degree of concordance among these two approaches to detect genetic variability. Sixty-nine F2 plants were obtained by selfing the SCH (ToUNR18xToUNR1). The parental RIL were derived from an interspecific cross between...

A multivariate indicator to monitor changes in spatial patterns of age-structured fish populations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Petitgas, Pierre; Poulard, Jean-charles.
Quantitative analysis of the spatial patterns in age-structured fish populations provides a useful complement to stock assessment methods. The spatial distribution of an age-structured population is characterized by indicators for location, dispersion and aggregation, which are estimated from survey data. The times series of spatial indicators are organised in a 3D data structure with dimensions along indicators, age classes and years. Multi factor analysis (MFA) is applied to quantify the reproducibility in time of the multivariate structure between age classes and indicators. MFA computes the mean annual pattern over the age classes. The deviation around that pattern in each year is also quantified. A multivariate indicator that characterise the spatial...

A Multivariate Regression Approach to Adjust AATSR Sea Surface Temperature to In Situ Measurements
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Tandeo, Pierre; Autret, Emmanuelle; Piolle, Jean-francois; Tournadre, Jean; Ailliot, Pierre.
The Advanced Along-Track Scanning Radiometer (AATSR) onboard Envisat is designed to provide very accurate measurements of sea surface temperature (SST). Using colocated in situ drifting buoys, a dynamical matchup database (MDB) is used to assess the AATSR-derived SST products more precisely. SST biases are then computed. Currently, Medspiration AATSR SST biases are discrete values and can introduce artificial discontinuities in AATSR level-2 SST fields. The new AATSR SST biases presented in this letter are continuous. They are computed, for nighttime and best proximity confidence data, by linear regression with different MDB covariables (wind speed, latitude, aerosol optical depth, etc.). As found, the difference between dual-view and nadir-only SST...

The aim of this work is to contribute to the definition of an analytical approach for evaluating the dynamics in progress in the agricultural and rural development at a territorial level. For this purpose principal components analysis and cluster analysis were applied and the different methodological approaches reviewed. A two-stage method is also proposed. This could provide the analytical tools to simplify and interpret the results of the territorial analyses, also in order to supply a flexible instrument to policy-makers. A case-study on the Emilia-Romagna region, in Italy, is presented.

Multivariate statistical methods are useful tools complementary to classic univariate methods. In biology, they are used in several scenarios where data structure, classification and grouping are necessary. Nevertheless, it seems they have not been employed in the study of non-parasitic phase of ticks or any other arthropod. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 26, 28, 30, 32, and 34ºC and four relative humidities 100, 80, 75.5 and 70% over the cycle variables of Anocentor nitens looking for establishing the most suitable environmental conditions to increase or decrease ticks performance and to apply these knowledges to zoogeography....

A mussel (Mytilus edulis) tissue certified reference material for the marine biotoxins azaspiracids
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mccarron, Pearse; Giddings, Sabrina D.; Reeves, Kelley L.; Hess, Philipp; Quilliam, Michael A.
Azaspiracids (AZAs) are lipophilic biotoxins produced by marine algae that can contaminate shellfish and cause human illness. The European Union (EU) regulates the level of AZAs in shellfish destined for the commercial market, with liquid chromatography-mass spectrometry (LC-MS) being used as the official reference method for regulatory analysis. Certified reference materials (CRMs) are essential tools for the development, validation, and quality control of LC-MS methods. This paper describes the work that went into the planning, preparation, characterization, and certification of CRM-AZA-Mus, a tissue matrix CRM, which was prepared as a wet homogenate from mussels (Mytilus edulis) naturally contaminated with AZAs. The homogeneity and stability of...

The development of multi-analyte methods for lipophilic shellfish toxins based on liquid chromatography-mass spectrometry permits rapid screening and analysis of samples for a wide variety of toxins in a single run. Validated methods and appropriate certified reference materials (CRMs) are required to ensure accuracy of results. CRMs are essential for accurate instrument calibration, for assessing the complete analytical method from sample extraction to data analysis and for verifying trueness. However, CRMs have hitherto only been available for single toxin groups. Production of a CRM containing six major toxin groups was achieved through an international collaboration. Preparation of this material, CRM-FDMT1, drew on information from earlier studies as...

A mutant cell line partially responsive to both IFN-a and IFN-g
Provedor de dados: Brazilian Journal of Medical and Biological Research
A recessive mutant cell line, B7, which is partially responsive to both interferon (IFN)-&lt;FONT FACE="Symbol"&gt; a&lt;/font&gt; and IFN-&lt;FONT FACE="Symbol"&gt;g&lt;/font&gt; is described. B7 was FACS sorted from a cellular pool, which was obtained from the parental cell line 2C4, after several rounds of mutagenesis. The partial responsiveness to IFN was observed both in terms of expression of cell surface markers (CD2, class I and II HLAs) and mRNA expression of IFN-stimulated genes (9-27; 6-16; 2'-5' OAS; GBP and HLA-DRa). A genetic cross with the U4 mutant (JAK1-, a member of the Janus family of nonreceptor tyrosine kinase) did not restore full IFN-responsiveness to B7, and JAK1 cDNA transfection into B7 restored the wild phenotype of the cell...

Autores: Karimi,Maryam; Karimian,Khashayar; Heli,Hossein.
A self-nanoemulsifying drug delivery system (SNEDDS) composed of ethyl oleate, Tween 80 and polyethylene glycol 600 was prepared as a new route to improve the efficacy of imatinib. The drug-loaded SNEDDS formed nanodroplets of ethyl oleate stabilized by Tween 80 and polyethylene glycol 600 with a diameter of 81.0±9.5 nm. The nanoemulsion-based delivery system was stable for at least two months, with entrapment efficiency and loading capacity of 16.4±0.1 and 48.3±0.2%, respectively. Imatinib-loaded SNEDDS was evaluated for the drug release profiles, and its effectiveness against MCF-7 cell line was investigated. IC50 values for the imatinib-loaded SNEDDS and an imatinib aqueous solution were 3.1 and 6.5 µg mL-1, respectively.

Autores: Davies, A.M.R.; Maxted, N.; Maesen, L.J.G. van der.
A comprehensive morphological survey and analysis of all taxonomically recognised wild species of Cicer L. (Leguminosae, Cicereae) is presented. The data (104 characters from 152 herbarium specimens representing 34 of the 44 recognised taxa in the genus Cicer with supplementary data for the remaining taxa taken from the literature) were analysed using multivariate statistics (cluster analysis, factor analysis and ordination techniques). The results are discussed in the context of extant classifications and the re-organisation of a novel infrageneric classification also incorporating information from published genetic data. A revised classification with 3 subgenera, 5 sections and 2 series is proposed.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Joyce, Terrence M.; Toole, John M.; Klein, Patrice; Thomas, Leif N.
Layering of ocean velocity fine structure has been coherently observed across the entire extent of a Gulf Stream warm-core ring using a shipboard acoustic Doppler current profiler system in September 2009 and independently sampled as the ring transited a moored array. Lines of constant velocity phase generally followed isopycnals as they deepened within the ring center. We also observed a clear separation of the vertical structure of the flows associated with the ring (of order 0.5m/s) with the shorter (200m) and less energetic (similar to 0.2m/s) flows of the velocity fine structure, which was further observed to rotate clockwise with increasing depth, consistent with downward propagating near-inertial waves (NIWs). Observations are consistent with a...

Autores: Goodwin,   Harold L., Jr.; Djunaidi,   Harjanto.
Most studies on price relationships in spatial markets assume that perfect information is a public good.  However, during the last two decades, the food industry in the U.S. has experienced a dramatic structural change, as have the structures of commodity markets; this is especially the case in the broiler industry. Tests for the presence of market integration are conducted within the framework of Neo-classical theory of the firm.  Grower costs and transportation in five southern U.S. broiler states (AL, AR, GA, MS, NC) are considered in deriving necessary conditions before any conclusion on market integration is reached. Using both parametric and nonparametric tests, this study found that all price pairs have a long-run price relationship and markets are...

A neural model for the visual tuning properties of action-selective neurons
Provedor de dados: Nature Precedings
Autores: Martin A. Giese; Vittorio Caggiano; Falk Fleischer.
SUMMARY: The recognition of actions of conspecifics is crucial for survival and social interaction. Most current models on the recognition of transitive (goal-directed) actions rely on the hypothesized role of internal motor simulations for action recognition. However, these models do not specify how visual information can be processed by cortical mechanisms in order to be compared with such motor representations. This raises the question how such visual processing might be accomplished, and in how far motor processing is critical in order to account for the visual properties of action-selective neurons.&amp;#xd;&amp;#xa;We present a neural model for the visual processing of transient actions that is consistent with physiological data and that accomplishes...

The Atlantic Ocean is one of the most important sinks for atmospheric carbon dioxide (CO2), but this sink has been shown to vary substantially in time. Here we use surface ocean CO2 observations to estimate this sink and the temporal variability from 1998 through 2007 in the Atlantic Ocean. We benefit from (i) a continuous improvement of the observations, i. e. the Surface Ocean CO2 Atlas (SOCAT) v1.5 database and (ii) a newly developed technique to interpolate the observations in space and time. In particular, we use a two-step neural network approach to reconstruct basin-wide monthly maps of the sea surface partial pressure of CO2 (pCO(2)) at a resolution of 1 degrees x 1 degrees From those, we compute the air-sea CO2 flux maps using a standard gas...

A never-ending story: the steadily growing family of the FA and FA-like genes
Provedor de dados: Genetics and Molecular Biology
Autores: Gueiderikh,Anna; Rosselli,Filippo; Neto,Januario B.C.
Abstract Among the chromosome fragility-associated human syndromes that present cancer predisposition, Fanconi anemia (FA) is unique due to its large genetic heterogeneity. To date, mutations in 21 genes have been associated with an FA or an FA-like clinical and cellular phenotype, whose hallmarks are bone marrow failure, predisposition to acute myeloid leukemia and a cellular and chromosomal hypersensitivity to DNA crosslinking agents exposure. The goal of this review is to trace the history of the identification of FA genes, a history that started in the eighties and is not yet over, as indicated by the cloning of a twenty-first FA gene in 2016.

Provedor de dados: Brazilian Journal of Microbiology
Autores: Coelho,Sheila Lorena de Araújo; Magalhães,Valter Cruz; Marbach,Phellippe Arthur Santos; Cazetta,Marcia Luciana.
Abstract Cyclodextrin glycosyltransferase (CGTase) catalyzes the conversion of starch into non-reducing cyclic sugars, cyclodextrins, which have several industrial applications. This study aimed to establish optimal culture conditions for β-CGTase production by Bacillus sp. SM-02, isolated from soil of cassava industries waste water lake. The optimization was performed by Central Composite Design (CCD) 2, using cassava flour and corn steep liquor as substrates. The maximum production of 1087.9 U mL−1 was obtained with 25.0 g L−1 of cassava flour and 3.5 g L−1 of corn steep after 72 h by submerged fermentation. The enzyme showed optimum activity at pH 5.0 and temperature 55 °C, and maintained thermal stability at 55 °C for 3 h. The enzymatic activity was...

A new allele of peptidase-B in cattle
Provedor de dados: Brazilian Journal of Genetics
Electrophoretic analyses of peptidase-B were carried out on red cell hemolysates from Holstein, Mantiqueira and Gyr cattle, using cornstarch, known in Brazil as Penetrose-30. We describe a new peptidase-B allele, denoted Pep-B1, in Mantiqueira cattle, belonging to the Bos taurus group, which are the result of a cross of native cattle of Portuguese origin introduced in Brazil during colonial times (16th century) with Holstein and Caracu cattle. The genetic control of peptidase-B was determined by typing parents and progeny segregating for all three alleles, confirming that peptidase B is controlled by a single autosomal locus with three codominant alleles, denoted Pep-B1, Pep-B2 and Pep-B3 The use of the citrate-phosphate buffer system, at pH 5.9, on 14%...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Kochummen, K.M.; Wong, K.M.
A new species, Alstonia undulifolia Kochummen &amp; Wong, is described from the Malay Peninsula. Two sections of the genus occur in the Malay Peninsula, Alstonia sect. Monuraspermum Mon. and Alstonia sect. Alstonia, the latter being the correct name for what was previously known as sect. Pala (Adr. Juss.) Benth. Various characteristics, including growth architecture, are examined for their usefulness in distinguishing these two sections of the genus. In comparing A. angustiloba Miq. and A. pneumatophora Berger, both of which have not been properly differentiated by characteristics of the reproductive organs, A. pneumatophora var. petiolata Mon. is reduced to synonymy under A. angustiloba.

A new and primitive retrobursal planarian from Australian fresh waters (Platyhelminthes, Turbellaria, Tricladida)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ball, Ian R.
A primitive freshwater planarian, Eviella hynesae gen. et sp. nov. is described from Australia. It is characterized by its lack of eyes and pigment, possession of caudally branched oviducts, and fully fused testes. Although a primary bursa is absent, its function being taken over by the modified female genital canal, the female copulatory system is posterior to the male system. Despite this maricolan feature, and other similarities with primitive southern hemisphere freshwater planarians that have been classified in the Maricola, the present species is placed in the family Dugesiidae of the Paludicola. Evidence from its sensory organs suggests that it belongs on the main evolutionary line from which the majority of Australasian freshwater planarians have...

Autores: Flood, Per R.
A new appendicularian, Oikopleura gorskyi n. sp., recovered from numerous plankton samples taken at depths between 1200 and 400 m in Sognefjorden, western Norway, as well as in more shallow water in this and other western Norwegian fjords, is described. The species is easily identified by the limited extension of its oikoblastic epithelium, the small size of its right stomach lobe and the disposition of its subchordal cells in two segments of an antero-posterior line with some 13 and 8 plateshaped cells respectively. The unique pattern of its house rudiment inclusion body and the unique cell nuclear pattern in its oikoblastic epithelium are additional, although less easily observable, characters of this species.

A new application of principal response curves for summarizing abrupt and cyclic shifts of communities over space
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Auber, Arnaud; Travers-trolet, Morgane; Villanueva, Ching-maria; Ernande, Bruno.
There is a growing need to easily describe and synthesize the dynamics of ecosystems’ components in space and time. Most multivariate analyses provide ordination diagrams or biplots that are too cluttered to allow simple reading and are unfamiliar to most users. To overcome such difficulties, a novel application of principal response curves (PRCs) is proposed. Principal response curves are traditionally used to assess treatment effects on community structure measured repeatedly over time. In this new application, the tested factor and the repeated-observation axis are replaced by time and space, respectively. The georeferencing of sampling sites permits to produce an easy-to-read map that summarizes both the temporal dynamics of the community and the...

A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
Provedor de dados: Genetics and Molecular Biology
Autores: Xing,Shaochen; Cai,Yuhong; Zhou,Kaida.
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2 population had a stable agronomical performance in field trials, as confirmed by the F-test. The stability of the F2 population was further substantiated by molecular analysis with simple sequence repeat markers. Specifically, of 160 markers assayed, 37 (covering all 12 chromosomes) were polymorphic between the parental lines. Testing the F1 hybrid individually with these markers showed that each PCR...

ABSTRACT This study aimed to investigate pirarucu's (Arapaima gigas) ability to trigger a self-feeding system to regulate protein intake between two standard diets that contained 39% and 49% of crude protein. The same system allowed the evaluation of daily feeding and locomotor activity rhythms. Eighteen fish (654.44±26.85g) were distributed into six 250 L tanks (3 fish/tank). Fish had free access to both diets (39% vs. 49% protein) by feeders (2 per tank), adapted to be activated by fish themselves. This system was connected to a computer system. After an adaptation period, fish learned to activate feeders and the mean food intake recorded was 2.14% of their body weight on a daily basis. Fish showed feeding (72.48%) and locomotor (72.49%) activity...

A New Approach to Humus Balancing in Organic Farming
Provedor de dados: Organic Eprints
Autores: Brock, Christopher; Hoyer, Uta; Leithold, Günther; Hülsbergen, Kurt-Jürgen.
Humus balances provide a profitable approach for humus dynamics assessment in farming practice. Nevertheless, there is a clear demand for methodological adaptation.     This article presents a new approach to humus balancing using reproducible algorithms for the estimation of balance coefficients. Humus balance coefficients for crops and organic fertilizers are estimated according to a bipartite algorithm. Humus demand  is calculated on the basis of crop yields referring to the nitrogen household in the plant-soil system. Humus supply is derived from organic matter input with plant material and fertilizers. The new approach facilitates the adaptation of the method to new situations.

A new approach to soil tillage for organic vegetable production: permanent beds
Provedor de dados: Organic Eprints
Autores: Vedie, Hélène; Berry, Dominique; Leclerc, Blaise; Grébert, David; Lhôte, Jean-Michel.
The effect of controlled traffic with permanent crop beds was compared to mouldboard ploughing in France for organic vegetable production. Four trials were carried out over a period of three to seven years at four sites with different pedo-climatic conditions. Variable results were obtained, depending on soil type (susceptibility to compaction), tillage machinery type, vegetable type (root or not, grown from seed or transplant) and weed development. However, permanent crop beds with controlled traffic generally improved biological activity and reduced labour demand.

A lot of methods were created in last decade for the spatio-temporal analysis of multi-electrode array (MEA) neuronal data sets. All these methods were implemented starting from a channel to channel analysis, with a great computational effort and  onerous spatial pattern recognition task. &amp;#xd;&amp;#xa;Our idea is to approach the MEA data collection from a different point of view, i.e. considering all channels simultaneously. We transform the 2D plus time MEA signal in a mono-dimensional plus time signal and elaborate it as a normal 1D signal, using the Space-Amplitude Transform method. &amp;#xd;&amp;#xa;This geometrical transformation is completely invertible and allows to employ very fast processing algorithms. &amp;#xd;&amp;#xa;

Provedor de dados: Open Marine Archive
Autores: Devresse, B.; Candreva, P.; Léger, P.; Sorgeloos, P.
The weaning of marine fish larvae is a critical step in larval rearing. The successful transition from live food to an artificial feed depends among others on the quality of the dry feed used (e.g. freshness of ingredients, digestibility, quality of the formulation) and the larvae themselves (e.g. age, behaviour towards artificial diets, development of the digestive tract, efficiency of certain metabolic pathways). The present study shows the results obtained with a new artificial diet formulated for the weaning phase of marine fish larvae (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) in commercial hatcheries.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ablain, M.; Cazenave, A.; Valladeau, G.; Guinehut, S.
A new error budget assessment of the global Mean Sea Level (MSL) determined by TOPEX/Poseidon and Jason-1 altimeter satellites between January 1993 and June 2008 is presented using last altimeter standards. We discuss all potential errors affecting the calculation of the global MSL rate. We also compare altimetry-based sea level with tide gauge measurements over the altimetric period. Applying a statistical approach, this allows us to provide a realistic error budget of the MSL rise measured by satellite altimetry. These new calculations highlight a reduction in the rate of sea level rise since 2005, by similar to 2 mm/yr. This represents a 60% reduction compared to the 3.3 mm/yr sea level rise (glacial isostatic adjustment correction applied) measured...

Autores: Duval, David; Pichon, Rémi; Lassalle, Damien; Laffitte, Maud; Gourbal, Benjamain; Galinier, Richard.
Thioester-containing proteins (TEPs) superfamily is known to play important innate immune functions in a wide range of animal phyla. TEPs are involved in recognition, and in the direct or mediated killing of several invading organisms or pathogens. While several TEPs have been identified in many invertebrates, only one TEP (named BgTEP) has been previously characterized in the freshwater snail, Biomphalaria glabrata. As the presence of a single member of that family is particularly intriguing, transcriptomic data and the recently published genome were used to explore the presence of other BgTEP related genes in B. glabrata. Ten other TEP members have been reported and classified into different subfamilies: Three complement-like factors (BgC3-1 to BgC3-3),...

A new cave species of Rhamdia (Siluriformes: Heptapteridae) from Serra do Ramalho, northeastern Brazil, with notes on ecology and behavior
Provedor de dados: Neotropical Ichthyology
Autores: Bichuette,Maria Elina; Trajano,Eleonora.
Rhamdia enfurnada, a new troglobitic (exclusively subterranean) catfish, is described from the Gruna do Enfurnado, Serra do Ramalho, southwestern Bahia State, middle São Francisco River basin. It differs from epigean congeners from the São Francisco River basin by the variable eye size, ranging from reduced to externally invisible (bilateral asymmetry in development of eyes is frequently observed), with a conspicuous orbital concavity (orbital diameter varying from 6.4 to 13.6% of head length in R. enfurnada and from 14.5 to 24.4% in the epigean species); by the dark pigmentation reduced due to a decrease in density of melanophores, and also variable. In comparison to other cave species, R. enfurnada presents a low degree of troglomorphism regarding...

Autores: Jurriaanse, J.H.; Lindemans, J.
Prof. J. F. van Bemmelen in Groningen has presented for the collection Jurriaanse a beautiful male Cethosia, captured on the isle of Boeton in Nov. '16, by Mr. N. H. Krans, medical officer of the Royal Dutch Navy. Comparing this Cethosia with specimen in the collection of the Leyden Museum of Natural History, we found there a female, captured on the same isle by Mr. T. Elbert in 1909. As it happened that this specimen was also quite different from all others and no descriptions or figures could be traced in the present litterature, we suppose that we have to do here with a new sub-species, closely allied to the species myrina Feldr. Dr. van Oort the director of said Museum has been kind enough to lend this female specimen for description. The following...

A new chemical strain of Cladonia furcata (Huds.) Schrad. (Lichenes)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Barendregt, A.; Dries, P.J.L. van den; Sipman, H.J.M.
The well-known and widespread lichen species Cladonia furcata (Huds.) Schrad. is usually very constant in its chemistry: fumarprotocetraric acid is its main secondary metabolite, sometimes accompanied by atranorin. Recently a new chemical strain, characterised by the presence of psoromic acid instead of fumarprotocetraric acid or atranorin, was found in Portugal by the first two authors during phytosociological investigations of heath vegetations. The plants are preserved in the herbarium of the Institute of Systematic Botany, University of Utrecht (U), leg. Barendregt &amp; v.d. Dries nr. 1-2 (U). Morphologically the plants with psoromic acid represent the slender form of C. furcata. which is the predominant form in lowland western Europe (fig. 1). The...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Karasawa, H.; Schweitzer, C.E.
A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds.

Cold-water coral (CWC) habitats can form complex structures which provide refuge, nursery grounds and physical support for a diversity of other living organisms, but despite their ecological significance, CWCs are still vulnerable to human pressures such as fishing, pollution, ocean acidification and global warming Providing coherent and representative conservation of vulnerable marine ecosystems including CWCs is one of the aims of the Marine Protected Areas networks being implemented across European seas and oceans under the EC Habitats Directive, the Marine Strategy Framework Directive and the OSPAR Convention. In order to adequately represent ecosystem diversity these initiatives require a standardised habitat classification that organises the variety...

A new combination and a new species in Saraca L. (Caesalpiniaceae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wilde, W.J.J.O. de.
During a precursory study in the genus Saraca it became evident that the number of fertile stamens and the size and degree of persistency of the bracteoles are major characters in the delimitation of the species. The genus extends from India and Ceylon to S.W. China and Tonkin, and as far east as to Celebes. The Celebes material (4 collections) was found to represent a species new to science. In the group with 6—8(—10) stamens, and with small (2—8 mm long) bracteoles, of which the Indian material was hitherto mostly referred to Saraca indica L., it appeared that two species are concerned, viz.: I. Bracteoles erect, clasping the pedicel, persistent. India, Ceylon, E. Pakistan, Burma west of the Irrawaddy River; otherwise cultivated. Fig. 1A Saraca asoca...

A new combination in Peristethium (Loranthaceae) expands the genus' range into the Amazon-Cerrado ecotone
Provedor de dados: Acta Amazonica
Autores: Caires,Claudenir Simões; Gomes-Bezerra,Kadja Milena; Proença,Carolyn Elinore Barnes.
The genus Peristethium, characterized by determinate inflorescences protected by deciduous bracts, occurs in the northwest of South America, as well as Costa Rica and Panama. The main objective of this paper was to transfer one species to what we believe is its correct generic placement in Peristethium, that likewise implies in a shift of the genus' distribution beyond the Amazon. A new combination, Peristethium reticulatum, is proposed, based on Struthanthus reticulatus, described from Tocantins in 1980. The sexual dimorphism of the inflorescences of P. reticulatum (sessile male flowers and pedicellate female flowers) associated with male inflorescences that are inserted at leafless nodes are unique within the genus. The male flowers have dimorphic...

The objective of this study was to determine the damage levels caused by Orthezia praelonga Douglas, 1891 and Leucoptera coffeella (Guérin-Mèneville 1842), on rangpur lime and Obatã coffee leaves, respectively. Measurements were based on a new concept for the evaluation of the following plant physiological parameters: photosynthesis, stomatal conductance, leaf temperature and transpiration, and internal concentration of CO2 (by infrared analyzer). A negative correlation between infestation level and photosynthesis was found, where the negative inflexion point of the curve was considered as a reference for damage levels. The control level for O. praelonga is below the 7-13% limit for damaged leaf area (40 to 70 scales per leaf), while for L. coffeella it is...

A new contribution to the Late Quaternary tephrostratigraphy of the Mediterranean: Aegean Sea core LC21
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

Tephra layers preserved in marine sediments can contribute to the reconstruction of volcanic histories and potentially act as stratigraphic isochrons to link together environmental records. Recent developments in the detection of volcanic ash (tephra) at levels where none is macroscopically visible (so-called ‘crypto-tephra’) have greatly enhanced the potential of tephrostratigraphy for synchronising environmental and archaeological records by expanding the areas over which tephras are found. In this paper, crypto-tephra extraction techniques allow the recovery of 8 non-visible tephra layers to add to the 9 visible layers in a marine sediment core (LC21) from the SE Aegean Sea to form the longest, single core record of volcanic activity in the Aegean Sea....

ABSTRACT A new species of Corydoras is described from the rio Araguaia basin, Goiás, Brazil. The new species can be distinguished from its congeners by presenting the following features: infraorbital 1 with very large ventral laminar expansion; infraorbital 2 contacting compound pterotic; flanks densely covered by irregular black spots; and ventral surface of trunk densely covered by coalescent relatively well-developed platelets. It is also discussed the possibility that C. araguaiaensis comprehends a complex of species.

A new species of Corydoras is described from the rio São Francisco basin in northeastern Brazil, Minas Gerais and Bahia States. The new species is distinguished from most of its congeners by the anterior portion of the infraorbital 1 very large, conspicuously expanded towards the anteroventral margin of the snout and almost entirely covering its lateral margin. Other characters that distinguish the new species are the infraorbital 2 slender on its dorsal tip, contacting only sphenotic and not compound pterotic; and the presence of two laterosensory canals on trunk.

A new Costa Rican species of Drosophila visiting inflorescences of the hemi-epiphytic climber Monstera lentii (Araceae)
Provedor de dados: Revista Brasileira de Entomologia
Autores: Vilela,Carlos R.; Prieto,Danyi.
ABSTRACT Drosophila monsterae sp. nov. is described from 11 males and 13 females collected from the inside of closed inflorescences of Monstera lentii (Araceae) at 1810 m altitude in the Forest Reserve of Cerro de La Carpintera, Canton La Unión, Province of Cartago, Costa Rica. Although flies have been seen wandering and copulating inside the floral chambers of closed inflorescences during the floral female phase, eggs or larvae have not yet been found either in the spathe or in the fleshy spadix. The new species is related to Drosophila tristani Sturtevant, 1921, from San José, Costa Rica, from which it differs mainly by having smaller slightly circular compound eyes, distinctly broader genae (cheek index ca. 2.4 vs 5 in D. tristani), and the inner...

Abstract Fungal infections have become a concern for health professionals, and the emergence of resistant strains has been reported for all known classes of antifungal drugs. Among the fungi causing disease, we highlight those that belong to the genus Aspergillus. For these reasons, the search for new antifungals is important. This study examines the effects of a coumarin derivative, 4-acetatecoumarin (Cou-UMB16) both alone and together with antifungal drugs, and its mode of action against Aspergillus spp. Cou-UMB16 was tested to evaluate its effects on mycelia growth, and germination of Aspergillus spp. fungal conidia. We investigated its possible action on cell walls, on the cell membrane, and also the capacity of this coumarin derivative to enhance the...

Ocean-Waves-Atmosphere (OWA) exchanges are not well represented in current Numerical Weather Prediction (NWP) systems, which can lead to large uncertainties in tropical cyclone track and intensity forecasts. In order to explore and better understand the impact of OWA interactions on tropical cyclone modelling, a fully coupled OWA system based on the atmospheric model Meso-NH, the oceanic model CROCO and the wave model WW3 and called MSWC was designed and applied to the case of tropical cyclone Bejisa (2013-2014). The fully coupled OWA simulation shows good agreement with the literature and available observations.

Provedor de dados: Neotropical Ichthyology
Autores: Zanata,Angela M.; Sardeiro,Byanca; Zawadzki,Cláudio H.
A new species of Hypostomus Lacépède is described from the rio Paraguaçu basin, Bahia State, Brazil. The new species is distinguished from its congeners by having black and conspicuous dots on a pale background, which are similar in size on the head, trunk, and fins, along with ventral surface of head and abdomen naked or the latter plated exclusively on its anterior portion, absence of ridges on head and trunk, and caudal-fin lobes relatively similar in length. The new species further differs from the sympatric H. chrysostiktos by having seven branched dorsal-fin rays instead of 10-11 and represents the eleventh siluriform species endemic to the rio Paraguaçu basin.

A new Echinogammarus of the berilloni – group E. Aquilifer nov.sp., from the Pyrenees (Crustacea, Amphipoda)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Pinkster, S.
During a short trip in the western part of the Pyrenees in August 1968 many samples of Gammaridae were collected both on the French and Spanish slopes of this mountain chain. Most of the specimens collected appeared to belong to the species Echinogammarus berilloni (Catta, 1878), or to closely related forms, but likewise it became clear that there exists a great morphological diversity in this group ofE. berilloni. This diversity, often called variability, was noticed already by Spandl ( 1926 ) and Margalef ( 1956 ) and made a more detailed study desirable. A great difficulty is the absence of a good and detailed description and trustworthy figures ofE. berilloni. The following published figures may serve as a basis for recognition of this species : Catta,...

A new econometric test for asymmetric price adjustment by cointegration vector restrictions with an application to the U.S. and Dutch pork chains
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kuiper,   W. Erno; Pennings,   Joost M.E.; Verhees,   Frans J.H.M.
A new test of asymmetric price adjustment is proposed on the basis of the super-consistent cointegrating vector estimator in the Johansen (1995) cointegrating procedure. The super-consistency makes the test robust to misspecifications in the short-run model. Application of the test to the price spreads in the Dutch and U.S. pork chains reveals that in the Netherlands wholesalers might obtain extra price margin as a consequence of asymmetric price adjustment vis-à-vis the farmers.

A new engineering method for understanding extrusion cooking process
Provedor de dados: Organic Eprints
Autores: Cheng, Hongyuan; Friis, Alan.
A new engineering method is proposed to understand extrudate expansion and extrusion operation parameters for starch based food extrusion cooking process through dimensional analysis principle, i.e. Buckingham pi theorem. Three dimensionless groups, i.e. pump efficiency, water content and temperature, are suggested to describe the extrudate expansion. Using the three dimensionless groups, an equation is derived to express the extrudate expansion. The model has been used to correlate the experimental data for whole wheat flour and fish feed extrusion cooking. The average deviations of the correlation are respectively 5.9% and 9% for the whole wheat flour and the fish feed extrusion. An alternative 4-coefficient equation is also suggested from the 3...

A new enzymatic process for the treatment of phenolic pollutants
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Palma,Mauri Sergio Alves; Horn,Harald; Zilli,Mario; Pigatto,Gisele; Converti,Attilio.
This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o) and enzyme (C T) concentrations as independent variables. Experimental data of the residual phenol concentration (C P) were used to calculate the oxidation efficiency (η), initial oxidation rate (-r o) and time required to reach the end of reaction (t) that were selected as the responses. Under the optimal conditions (T = 45°C, pH 6.6, N = 400 rpm, C P,o = 100 ppm and C T = 50 U/mL), η was 88.1%, -r o = 10.2 mg L-1 min-1, t = 40 min. These results suggested that tyrosinase-rich crude extracts from vegetable byproducts could be quite promising.

A new arbuscular mycorrhizal, Paraglomus-like, fungal species (Glomeromycotina) was found and propagated in single-species cultures established from spores coming from Oman, Greece, Tunisia, and New Caledonia. The hyaline spores of the fungus are small, 17–67 μm diam. when globose. Their spore wall consists of an evanescent, 1.0–2.3 μm thick, short-lived outer layer and a laminate, smooth, 3.8–7.3 μm thick inner layer, of which none shows amyloid or dextrinoid reaction in Melzer's reagent. Mycorrhizal structures (arbuscules and hyphae without vesicles) of the fungus stained slightly in Trypan blue, thus like those of the formerly described Paraglomus spp., in which the histochemical feature has been recognized.

Autores: Meij, S.E.T. van der.
A new species of gall crab is described from the free-living stony coral Trachyphyllia geoffroyi. Specimens were collected during field work in Lembeh Strait (Indonesia) and of Kudat (Malaysian Borneo). This new species, here named Lithoscaptus semperi sp. n., is the ninth species assigned to the genus. It can be separated from its congeners by not having the internal orbital angle extending beyond the external orbital angle, and by the stout female P2 merus with prominent distomesial projection. In addition, the carapace surface appears smooth, despite having small tubercles on the anterior half, and is without noticeable spines, other than those on the frontal margin. The distinctive carapace pattern in life is a diagnostic character in male specimens.

A NEW GENERAL CONCEPTUAL APPROACH TO MODELING THE LIVESTOCK SECTOR: AN APPLICATION TO THE JAPANESE SWINE-PORK SECTOR
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fabiosa,   Jacinto F.; Qi,   Xiaoting.
Many livestock sector models have limited coverage of relevant variables, and are somewhat ad hoc in their choice of what should be specified as behavioral equations.  This study develops a generic conceptual approach to modeling the livestock sector that provides consistent rules of specification and better coverage of variables.  This approach is then applied to the swine-pork sector of Japan.  The new approach departs significantly from existing models.  The structure clearly differentiates stock and flow variables; only flow variables have behavioral specifications and stock variables are accounting identities; flow variables are expressed in rates rather than levels; logistic functions are used in most flow variables to automatically impose...

In the following lines a very interesting new genus of the group Rhynchophoridae will be established. A single male specimen, from the Upper Mahakam (Borneo), has been found in a small collection of natural history objects, presented to the Leyden Museum in December of last year by Mr. Kampmeinert. The species is dedicated to the donor. The nearest ally of this new genus, for which I propose the name Mahakamia, is Macrocheirus Schönh. The characters by which the two genera are differentiated in the male sex (the female sex of my insect is as yet unknown) are very conspicuous, as will be seen from the following table.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Doesburg Jr., P.H. van.
Dedicated to Dr. H. C. Blöte on the occasion of his 70th birthday. In the collection of the Rijksmuseum van Natuurlijke Historie at Leiden, the author found a peculiar and most interesting specimen belonging to the Heteropterous family Velocipedidae. It appears to be quite different from the representatives of Scotomedes Stål, 1873, the only genus hitherto known is this family. The specimen is not in a very good state of preservation, but complete enough to serve as the basis for the following description. Bloeteomedes nov. gen. Typus: Β. borneensis nov. spec. Distinguishable from Scotomedes by the following characters: head longer, more cylindrical, underside without a median keel; first antennal segment extending far beyond apex of head, its length more...

A new genus and species of Euptychiina (Lepidoptera: Nymphalidae: Satyrinae) from southern Brazil
Provedor de dados: Neotropical Entomology
Autores: Freitas,AVL; Mielke,OHH; Moser,A; Silva-Brandão,KL; Iserhard,CA.
This paper describes a new genus and a new species of Euptychiina from open grassland habitats (campos de cima da serra) in southern Brazil. The systematic position of this new taxon is discussed based on morphological and molecular data, and it is considered sister to Taydebis Freitas. Since the campos vegetation is considered endangered due to anthropogenic activities, this butterfly species deserves attention and should be included in future conservation plans for this biome.

Autores: Ferreira,Katiane M.; Menezes,Naércio A.; Quagio-Grassioto,Irani.
Lepidocharax, new genus, and Lepidocharax diamantina and L. burnsi new species from eastern Brazil are described herein. Lepidocharax is considered a monophyletic genus of the Stevardiinae and can be distinguished from the other members of this subfamily except Planaltina, Pseudocorynopoma, and Xenurobrycon by having the dorsal-fin origin vertically aligned with the anal-fin origin, vs. dorsal fin origin anterior or posterior to anal-fin origin. Additionally the new genus can be distinguished from those three genera by not having the scales extending over the ventral caudal-fin lobe modified to form the dorsal border of the pheromone pouch organ or to represent a pouch scale in sexually mature males. In this paper, we describe these two recently discovered...

A new genus of Neotropical rheophilic catfishes, with four new species (Teleostei: Siluriformes: Pseudopimelodidae)
Provedor de dados: Neotropical Ichthyology
Autores: Shibatta,Oscar Akio; Vari,Richard P.
ABSTRACT Rhyacoglanis, a new genus of the South American freshwater catfish family Pseudopimelodidae is described from cis-Andean portions of the continent. Rhyacoglanis is distinguished from other genera of the family by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. Species of Rhyacoglanis are rheophilic and strongly associated with rapids and other swift-flowing waters. A phylogenetic analysis based on 41 morphological characters yields a hypothesis of monophyly of the Pseudopimelodidae and Rhyacoglanis. Pimelodus pulcher Boulenger, 1887, from the western Amazon basin is designated as type-species of the new...

A new pontocypridid genus, &lt;i&gt;Peripontocypris&lt;/i&gt; gen. nov. and two new species are described from the Maldive Islands, Papua New Guinea and from Easter Island. The new genus has a remarkable set of characters, which are unknown in other members of the family: six adductor muscle scars, a Y-shaped Zenker's organ and a large furca. Some other characters of the valves and the soft parts are reminiscent of different pontocypridid genera, and suggest a mosaic type of evolution. The affinities of &lt;i&gt;Peripontocypris&lt;/i&gt; with other genera, and its taxonomic position are discussed.

A new, harmless, high-throughput endosperm-based DNA extraction method for wheat
Provedor de dados: Ciência Rural
Autores: Ma,Zhihui; Wang,Yuquan; Wei,Wenhui; Ru,Zhengang.
ABSTRACT:  In this study, a non-destructive, high-throughput, endosperm-based DNA extraction method was developed. To verify the non-destructive nature of this method, a germination test was performed on 288 seeds after sampling their endosperm, which gave a seedling emergence rate that was higher (97.6%) than that of the control group (92%). To confirm the feasibility of the new method, DNA was extracted from plants of a BC1F2 population by two different methods, namely, from endosperm using our rapid, high-throughput method (ER-DNA) and from young leaves emerging from the same sampled seed using the CTAB method (LC-DNA). The ER-DNA was undetectable by agarose gel electrophoresis, but was found to be an adequate replacement for LC-DNA for the...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Dessein, S.; Robbrecht, E.; Smets, E.
Spermacoce heteromorpha Dessein (Rubiaceae, Spermacoceae) is newly described and illustrated. It grows on the Marungu highlands of the Democratic Republic of the Congo (D.R. Congo) at altitudes of 1800 to 1900 m. The species resembles the Tanzanian Spermacoce taylorii Verdcourt, from which it mainly differs in having terminal inflorescences, only slightly exserted anthers, and densely pubescent stems. Moreover, Spermacoce heteromorpha features marked heterophylly, with long leaves at the plant’s base and much shorter cauline leaves, a type of heterophylly rarely observed in Spermacoce or in the Rubiaceae as a whole. The finding of this species exemplifies the unique floristic richness of this underexplored part of D.R. Congo.

When arranging a part of the Carabidae collection of the Leiden Museum, I noted that the specimens labelled Hexagonia lucassenii Van de Poll (1889: 249-250) did not constitute a homogeneous material.

A new innovated and cheep model in building artificial reefs
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Mahmoud, M.A.; Ammar, M.S.A.
A novel and cheep approach for building artificial reefs was designed in such a way that sediments in an area of high sedimentation rate will be utilized in building the artificial substrate with no further sediment accumulation afterwards. The model consists of several steel cylinders which are soldered together in such a way to form a reef flat, a gentle slope and a steep slope, with two layers of narrow opening meshes (a lower plastic and an upper metallic one). Within a short periode (3 months), a substrate layer of a total of ~ 1 cm was formed between the two meshes, this layer increased to ~2 cm after 9 months. Transplants of the three species Stylophora pistillata, Echinopora gemmacea and Montipora spongiosa grow better when the attaching surface is...

A new karyotype for the genus Cavia from a southern island of Brazil (Rodentia - Caviidae)
Provedor de dados: Genetics and Molecular Biology
Autores: Gava,A.; Freitas,T.R.O.; Olimpio,J.
Intraspecific karyotype variation in mammal species is very common and often caused by centromeric fusion of acrocentric chromosomes. We describe here a new karyotype 2n = 62 (FN = 112) for the genus Cavia from the Moleques do Sul Islands, of the southern coast of Brazil. We analyzed two male and four female karyotypes that had twenty-four biarmed pairs and six pairs of acrocentric chromosomes. The sexual pair consisted of a metacentric X-chromosome and a large acrocentric Y. C-bands were found in the centromeric and pericentromeric regions of almost all chromosomes, except for some small biarmed and acrocentric ones. Nucleolus organizer regions appeared in two biarmed chromosomes, and G-banding patterns were also seen.

A new karyotype of Calomys (Rodentia, Sigmodontinae)
Provedor de dados: Iheringia Série Zoologia
Autores: Lima,J. Fernando de S.; Kasahara,Sanae.
The genus Calomys Waterhouse, 1837 is widely distributed within South America, being found in Venezuela, Colombia, Peru, Bolivia, Brazil, Paraguay, Uruguay and Argentina. Specimens of Calomys were collected in Formoso do Araguaia, Tocantins, Brazil. For chromosome characterization standard staining techniques and as G-banding and nucleolar organizer region were used. The karyotype was 2n=46 and AN=66. The X chromosome is a medium metacentric and the Y chromosome a small acrocentric chromosome. Chromosome homologies with other species were observed. Probably, karyotype differences were basically due to Robertsonian rearrangements.

A new karyotype of Wiedomys pyrrhorhinus (Rodentia: Sigmodontinae) from Chapada Diamantina, northeastern Brazil
Provedor de dados: Revista Brasileira de Zoologia
Autores: Souza,Ana L. G; Corrêa,Margaret M. de O; Aguilar,Cecília T. de; Pessôa,Leila M.
A new karyotype of Wiedomys pyrrhorhinus (Wied, 1821) is described, including G- and C-banding and Ag-NOR sites from specimens collected in the municipality of Morro do Chapéu, situated in the northern region of the Chapada Diamantina, state of Bahia. Karyological studies of W. pyrrhorhinus have shown a constant diploid number (2n) of 62 with two different numbers of autosomal arms (FNa): 86 and 90, respectively. The new karyotype revealed 2n = 62 and FNa = 104, being the higher autosomal number found so far for this genus. The X chromosome is a large acrocentric and the Y chromosome is a small acrocentric. The analysis of the karyotype morphology suggests that this new karyotype is more closely related to the previous karyotype with 2n = 62 and FNa = 90,...

A New Lease on Life for Marginal Farmland: Convergence of Prairie Restoration with Biofuel Production
Provedor de dados: Organic Eprints
Autores: Borsari, Bruno; Onwueme, Inno.
The prairie ecosystem that occupied most of the North American continent has been mostly converted into agricultural farmland.  The looming global scarcity of fossil fuels has spurred interest in producing ethanol from corn (Zea mays) but legitimate objections remain to the idea of supporting this vision.  The purpose of this study was to initiate a prairie restoration on marginal soil of a 16.2 ha. farm in southeastern Minnesota and to determine which restoration procedure (only native grass species versus a mixture of grasses and forbes) was most effective for the establishment of prairie on the land that may yield biomass for biofuels.  We planted 11.4Kg./ha. of grasses on 4.7 ha. and 0.70Kg./ha. of forbs on 3.2 ha., in June 2007.  An evaluation of...

A new lineage of Conoidea (Gastropoda: Neogastropoda) revealed by morphological and molecular data
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kantor, Yuri I.; Strong, Ellen E.; Puillandre, Nicolas.
The hyperdiverse group of venomous Conoidea has eluded attempts to construct a robust and stable classification owing to the absence of a robust and stable phylogenetic framework. New molecular data have greatly enhanced our understanding of conoidean evolution, allowing the construction of a new family-level classification. This expanding framework has also allowed the discovery of several independent lineages that merit recognition at familial rank. One of these, based on seven specimens collected over more than 20 years from deep waters off New Caledonia, represents a unique, monotypic lineage closely related to Mitromorphidae, which we here name as the new family Bouchetispiridae. This new lineage bears a unique combination of teleoconch, protoconch...

A new long-finned Corydoras Lacépède, 1803 (Siluriformes: Callichthyidae) from the lower rio Paraná basin, Brazil
Provedor de dados: Neotropical Ichthyology
Autores: Tencatt,Luiz F. C.; Britto,Marcelo R.; Pavanelli,Carla S.
A new species of Corydoras is described from the lower rio Paraná basin, just downstream from Itaipu Dam, Brazil, close to Paraguay boundary. The new species can be distinguished from most of its congeners by the infraorbital 2 with a posterior laminar expansion conspicuously reduced, first and second dorsal-fin branched rays conspicuously elongated in males, mesethmoid entirely covered by skin, and by the presence of four to six irregular black or brownish blotches on the midline of the flank. The probable occurrence of the new species in the floodplain of the upper portion of the rio Paraná drainage is discussed.

A new look into the small-scale dispersal of free-living marine nematodes
Provedor de dados: Revista Brasileira de Zoologia
Autores: Thomas,Micheli C; Lana,Paulo C.
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m and 1 m from the stained cores, sampling nets were suspended 5 and 10 cm above the sediment-water interface. Dispersion behaviors were defined as a function of a) the numbers of stained recaptured nematodes in comparison to their mean densities in the sediment, b) movement in the sediment or swimming in the water column, and c) body morphology. Tidal currents with average velocities of 9 cm/s resuspended...

A new low molecular mass alkaline cyclodextrin glucanotransferase from Amphibacillus sp. NRC-WN isolated from an Egyptian soda lake
Provedor de dados: Electronic Journal of Biotechnology
Autores: Al-Sharawi,Samar Z.R.; Ibrahim,Abdelnasser S.S.; El-Shatoury,Einas H; Gebreel,Hassan M; Eldiwany,Ahmad.
Background: Cyclodextrin glucanotransferase (CGTase) is one of the most industrially important enzymes used in the commercial production of cyclodextrins (CDs). Alkaliphilic bacteria have attracted much interest in the last few decades because of their ability to produce extracellular enzymes that are active and stable at high pH values. Here, we report the isolation of a new CGTase from alkaliphilic bacteria collected from Egyptian soda lakes and describe the purification and biochemical characterization of this CGTase. Results: Screening for CGTase-producing alkaliphilic bacteria from sediment and water samples collected from Egyptian soda lakes located in the Wadi Natrun valley resulted in the isolation of a potent CGTase-producing alkaliphilic...

A new Lucanoid beetle from Java
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ritsema Cz., C.
In a consignment of beetles, lately received from Mr. J. D. Pasteur and brought together by himself in Western Java (Mt. Poentjak, on the frontier between the districts of Buitenzorg and Preanger), I found among a fine series of Cladognathus giraffa Oliv. a specimen which was at once distinguished from the others by its more slender mandibles which were regularly curved downwards, and by the rounded, not obliquely truncate anterior angles of the prothorax. A more careful examination of this specimen showed me clearly that it had nothing to do with Cl. giraffa but that it was a very close ally of the interesting Prosopocoelus decipiens Parry ¹) from Malabar. The Javanese species is certainly undescribed and I propose to call it after its discoverer:

Autores: Sluys, Ronald.
A new species of marine triclad, Ectoplana undata n. sp., ectoparasitic on the horseshoe crab Tachypleus gigas, is described. Cocoons of triclads were found on T. gigas as well as on the horseshoe crab Carcinoscorpius rotundicauda; since from the latter species no triclads were collected, it remains unknown whether these cocoons are those of E. undata or of another species. The genus Ectoplana, though poorly defined, is here retained, for stated reasons, pending a revision of the Procerodidae.

Sequences from the sugarcane expressed sequence tag (SUCEST) database were analyzed based on their identities to genes encoding chalcone-synthase-like enzymes. The sorghum (Sorghum bicolor) chalcone-synthase (CHS, EC 2.3.1.74) protein sequence (gi|12229613) was used to search the SUCEST database for clusters of sequencing reads that were most similar to chalcone synthase. We found 121 reads with homology to sorghum chalcone synthase, which we were then able to sort into 14 clusters which themselves were divided into two groups (group 1 and group 2) based on the similarity of their deduced amino acid sequences. Clusters in group 1 were more similar to the sorghum enzyme than those in group 2, having the consensus sequence of the active site of chalcone and...

A new member of the crustacean suborder Ingolfiellidea from Bonaire, with a review of the entire suborder
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stock, Jan H.
A single specimen of an ingolfiellid was found in a slightly brackish well (locally called a “pos”) on the Bacuna estate in the island of Bonaire (Netherlands Antilles). The specimen differs from all other 21 ingolfiellid taxa, and is described as a new species, Ingolfiella (Gevgeliella) putealis. The two classification systems in use for the Ingolfiellidea, that of KARAMAN (1959) and that of RUFFO (1970), are compared and both are found not entirely satisfactory in the light of recent discoveries. A new system is devised, in which the suborder is divided into 2 families, together with 3 genera and 5 subgenera. The genera and subgenera do not only represent morphological unities, but also combine species with similar habitat requirements. Within the...

A New Method of De-Aliasing Large-Scale High-Frequency Barotropic Signals in the Mediterranean Sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hu, Denghui; Xu, Yongsheng.
With the development of satellite observation technology, higher resolution and shorter return cycle have also placed higher demands on satellite data processing. The non-tide high-frequency barotropic oscillation in the marginal sea produces large aliasing errors in satellite altimeter observations. In previous studies, the satellite altimeter aliasing correction generally relied on a few bottom pressure data or the model data. Here, we employed the high-frequency tide gauge data to extract the altimeter non-tide aliasing correction in the west Mediterranean Sea. The spatial average method and EOF analysis method were adopted to track the high-frequency oscillation signals from 15 tide gauge records (TGs), and then were used to correct the aliasing errors...

A new method to control error rates in automated species identification with deep learning algorithms
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Villon, Sébastien; Mouillot, David; Chaumont, Marc; Subsol, Gérard; Claverie, Thomas; Villéger, Sébastien.
Processing data from surveys using photos or videos remains a major bottleneck in ecology. Deep Learning Algorithms (DLAs) have been increasingly used to automatically identify organisms on images. However, despite recent advances, it remains difficult to control the error rate of such methods. Here, we proposed a new framework to control the error rate of DLAs. More precisely, for each species, a confidence threshold was automatically computed using a training dataset independent from the one used to train the DLAs. These species-specific thresholds were then used to post-process the outputs of the DLAs, assigning classification scores to each class for a given image including a new class called “unsure”. We applied this framework to a study case...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Coutinho,E.L.; Gomes,A.R.S.; França,C.N.; Salvini,T.F.
An alternative device for the immobilization of the hind limb of the rat was developed to study the effects of chronic disuse on the soleus and tibialis anterior muscles, maintained for 3 weeks in the shortening and the stretching positions, respectively. The proposed device is made of steel mesh and cotton materials, and has some advantages when compared to cast or plaster cast: it is cheaper, lighter (12 g or 4% of the body weight of the rat) and the same unit can be easily adjusted and used several times in the same animal or in animals of similar size. Immobilization is also useful to restrain the movements of the hip, knee, and ankle joints. Male rats (291 ± 35 g and aged 14 ± 2 weeks) were used to develop and test the model.

A new model for the population pharmacokinetics of didanosine in healthy subjects
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Velasque,L.S.; Estrela,R.C.E.; Suarez-Kurtz,G.; Struchiner,C.J.
Didanosine (ddI) is a component of highly active antiretroviral therapy drug combinations, used especially in resource-limited settings and in zidovudine-resistant patients. The population pharmacokinetics of ddI was evaluated in 48 healthy volunteers enrolled in two bioequivalence studies. These data, along with a set of co-variates, were the subject of a nonlinear mixed-effect modeling analysis using the NONMEM program. A two-compartment model with first order absorption (ADVAN3 TRANS3) was fitted to the serum ddI concentration data. Final pharmacokinetic parameters, expressed as functions of the co-variates gender and creatinine clearance (CL CR), were: oral clearance (CL = 55.1 + 240 x CL CR + 16.6 L/h for males and CL = 55.1 + 240 x CL CR for...

Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each...

This park, one of the largest natural reserves of the Atlantic Rain Forest in Brazil, is a hotspot of tropical biodiversity. The purpose of this study was to update existing information on the bathymetry and morphometric features of the lake, using differential GPS (DGPS) technology for data collection, coupled to a digital echo sounder. The bathymetry was based on the acquisition of 1106 points, where the depths as well as the geographic coordinates were obtained. The new study allowed the refinement of existing primary and secondary morphometric data for this lake.

A new name, and notes on extra-floral nectaries, in Lagunaria (Malvaceae, Malvoideae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Craven, L.A.; Miller, C.; White, R.G.
The Australian taxon Lagunaria patersonius subsp. bracteata is raised to specific rank as L. queenslandica, based upon morphological and ecological dissimilarities between it and the autonymic taxon, L. patersonius subsp. patersonius. The latter taxon occurs on the southwest Pacific Ocean islands, Lord Howe and Norfolk Islands. Extra-floral nectaries are reported in Lagunaria, apparently for the first time, and contrasted with those occurring in species of Hibiscus sections Bombicella and Furcaria.

A new name for the foraminiferal genus Heterospira
Provedor de dados: Naturalis Digital Academic Repository
Autores: Umbgrove, J.H.F.
A short time ago I described a new foraminiferal genus from the Tertiary of Borneo 1). I gave this genus the name of Heterospira. Mr. P. H. Oehser of Washington drew my attention to the fact that E. Koken as early as 1896²) had used the name Heterospira for a genus of triassic gastropoda from Hallstatt. Therefore according to the international rules of zoölogical nomenclature, the name Heterospira for a foraminiferal genus being a homonym has to be rejected.

Autores: Bouchet, P.; Kantor, Yu. I.; Sysoev, A.; Puillandre, N.
A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s....

A NEW PERSPECTIVE ON UNDERINVESTMENT IN AGRICULTURAL R&amp;D
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roseboom,   Johannes.
During the past 40 years, the returns to agricultural R&amp;D have been on average in the range of 40-60% (Alston, et al 2000, Evenson 2001). Many agricultural economists see this high average as convincing evidence that there is significant underinvestment in public agricultural R&amp;D (Ruttan 1980, Pinstrup-Andersen 2001).   This paper sheds new light on the underinvestment hypothesis by introducing a simple model of the selection of R&amp;D projects and confronting it with the rate-of-return evidence accumulated over the years worldwide. The model assumes that the distribution of all possible R&amp;D projects on an expected rate-of-return (ERR) scale declines asymptotically. Under the neoclassical conditions of full information and profit maximization,...

A new photosynthetic planktonic marine dinoflagellate, Azadinium dexteroporum sp. nov., is described from the Gulf of Naples (South Tyrrhenian Sea, Mediterranean Sea). The plate formula of the species, Po, cp, X, 4, 3a, 6, 6C, 5?S, 6'" and 2, is typical for this recently described genus. Azadinium dexteroporum is the smallest rep-resentative of the genus (8.5m average length, 6.2m average width) and shares the presence of a small antapical spine with the type species A.spinosum and with A.polongum. However, it differs from all other Azadinium species for the markedly asymmetrical Po plate and the position of the ventral pore, which is located at the right posterior end of the Po plate. Another peculiarity of A.dexteroporum is the pronounced concavity of...

A new preparatory approach of decapod and thoracican crustaceans from the Middle Danian at Fakse, Denmark
Provedor de dados: Naturalis Digital Academic Repository
Autores: Jakobsen, Sten Lennart.
Many papers on the taxonomy of fossil crustaceans are often based upon poorly preserved material and/or specimens that have been insufficiently prepared. The purpose of the present note is to outline some preparation methods that are applied in our (J.S.H. Collins and S.L.J.) ongoing studies of anomuran and brachyuran decapods from the Middle Danian limestones at Fakse quarry (Denmark), which have greatly enhanced the quality of our material. The techniques briefly outlined here involve: 1 – staining method; 2 – water blasting (as a cleaning tool in preparation of fossils); and 3 – negative preparation (with acid). Some of these techniques will have wide applications in other fields of paleontological research.

A New Process for Extracting Alginates from Laminaria digitata: Reactive Extrusion
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Vauchel, Peggy; Kaas, Raymond; Arhaliass, Abdellah; Baron, Regis; Legrand, Julien.
Alginates are natural polysaccharides that are extracted from brown seaweeds and widely used for their rheological properties. The main step in the extraction protocol used in the alginate industry is that of alkaline extraction. A batch process is used for this step, which is time-, water-, and reactant-consuming. The possibility of extracting by reactive extrusion was investigated. The reactive extrusion process appeared to be more efficient than the batch process for the alkaline extraction of alginates from Laminaria digitata in several key ways: Time demand is reduced from about an hour to only few minutes, water and reactant requirements are divided by more than a factor 2, extraction yield is 15% higher (relative enhancement), and the rheological...

A new protodidelphid (Mammalia, Marsupialia, Didelphimorphia) from the Itaboraí Basin and its implications for the evolution of the Protodidelphidae
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: CARNEIRO,LEONARDO M.
Abstract The Protodidelphidae was a group of marsupials that lived in Gondwana from the early to middle Eocene. Among South American faunas, the Itaboraí Basin calls attention by the presence of four genera and six species. Herein is described Bergqvistherium primigenia gen. et sp. nov., a new protodidelphid from the Itaboraí Basin - lower Eocene. This taxon differs from other protodidelphids in the smaller size, developed entocristid, less brachyo-bunoid adaptations, and entoconid more mesial than the hypoconid. These characters are recovered as plesiomorphies of the Protodidelphidae, supporting Bergqvistherium as an early-divergent lineage of this group. The Protodidelphidae fauna of the Itaboraí Basin is represented by less specialized “basal” taxa,...

A New Quantitative Method for Predicting Forensic Racial Identity Based on Dental Morphological Trait Analysis
Provedor de dados: International Journal of Morphology
Autores: Alsoleihat,Firas.
Few previous studies have demonstrated the likelihood of using the worldwide patterns of dental morphological variation in prediction of ancestry in the context of forensic dental anthropology. This paper introduces a new quantitative method for predicting forensic racial identity of individual specimens based on dental morphological trait analysis. In this study, the inter-population variation in the expression frequency of 16 non-metric tooth crown traits, manifested on the permanent dentition, was used for analysis. The method was developed from the notion that dental morphological characteristics, when viewed as sets of traits rather than isolated variables, can be utilized to calculate the relative probability that an individual belongs to a...

A NEW RECORD FOR THE MILK FROG Trachycephalus coriaceus (ANURA: HYLIDAE) FROM TELES PIRES RIVER, SOUTH AMAZONIA, BRAZIL
Provedor de dados: Acta Biológica Colombiana
Autores: FERREIRA,Vanessa Gonçalves; THALER,Rafaela; FOLLY,Henrique; DA SILVA,Leandro Alves.
ABSTRACT Herein, we report a new record of the milk frog Trachycephalus coriaceus for the Brazilian southern Amazonia and provide an updated geographic distribution map. We collected one specimen of T. coriaceus on 8 november 2016, during a nocturnal survey inside a dense ombrophilous forest in the right bank of the Teles Pires River, municipality ofJacareacanga, southern of Pará State. The record of T. coriaceus to Jacareacanga is the first to the State. The disjoint geographic distribution of this species along de Amazonia may just reflect the paucity of amphibian knowledge throughout this biome and the difficulty to detect this species in the field, given its explosive reproductive behavior.

A NEW REGIONAL HOUSEHOLD DEMAND SYSTEM FOR GTAP
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McDougall,   Robert.
The GTAP model, versions 4.1 and lower, suffers from some defects in the implementation of the regional household demand system. Most seriously, the upper level of the demand system assumes that each regional household faces a fixed price for utility from private consumption. But with a private consumption demand system of the CDE form, the price of utility from private consumption depends on the level of private consumption expenditure. With no fixed price for utility from private consumption, the familiar Cobb-Douglas demand system does not apply. Accordingly, the upper-level demand equations are in error. Furthermore, utility and equivalent variation are wrongly computed in simulations with non-standard settings for the CDE expansion parameters. Even...

A new Rhizopode of the genus Hyalosphenia Stein, 1857 (Protozoa; Sarcodina; Amoebina)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Graaf, Fr. de.
While studying the plankton community of the “Loenerveense Polder”, one of the lakes along the eastern bank of the river Vecht, I came across an unusually large form of the genus Hyalosphenia. The species occurred in a qualitative net sample taken from the open water. Only one living specimen and two empty thecae were then observed. Though numerous net samples were taken from the same locality throughout the year, I did not meet with the animal again, only empty thecae sometimes being found. However when for the purpose of recovering more specimens, samples of bottom mud were taken, the living animal was seen again, though only once, and in one living specimen. After that I did not succeed in catching the animal again. Describing a new species from such...

Abstract The present paper describes a new species of Actinote (Nymphalidae, Heliconiinae, Acraeini) from southeastern Brazil, and describes the morphology of the adults and immature stages of this species. Actinote mantiqueira sp. nov. occurs in the Serra da Mantiqueira and Serra do Mar in the Atlantic Forest. Adults from this population are very similar to other species of the “orangish red mimicry complex”, including Actinote alalia (C. Felder &amp; R. Felder, 1860), its sister species, restricted to the mountains of southern Brazil. Actinote mantiqueira sp. nov. and A. alalia are distinguishable by wing pattern, male genitalia and larval morphology, and have strongly allopatric distributions. A redescription of Actinote alalia is also provided.

Autores: Önder, F.
Introduction Recently I had the occasion to examine a collection of 230 unidentified specimens of the family Miridae kindly loaned to me for examination by the Rijksmuseum van Natuurlijke Historie, Leiden, Netherlands. All these were collected in Cyprus. Three specimens belong to the genus Alloeotomus Fieber and represent a new species which is described here. Until now the southernmost limits of the distribution of Alloeotomus were Sicily (Wagner, 1954) in the west and Peking (China) (Reuter, 1903) in the east. The discovery of the new species from Cyprus has extended this limit further to the south. There are now five species in the genus Alloeotomus including the new one. A key to facilitate their identification is given in this paper. Alloeotomus...

ABSTRACT During the Mosaico do Apuí expedition in 2006, a new species of Ancistrus was found in the rio Sucunduri, a large tributary of the rio Madeira basin in south Amazonas State. The new species has a unique color pattern for the genus and is distinguished by the presence of alternate light and dark vertical bars on the trunk. Other Ancistrini genera have species with a similar color pattern, but the new species is clearly distinguished by a lack of plates on the snout and presence of fleshy tentacles on the snout as in all Ancistrus representatives. We also provide comments on the taxonomic status of the A. bolivianus, A. heterorhynchus and A. marcapatae.

Among some fishes, forwarded by the late Dr. Bleeker to the Leyden Museum, I came across four specimens evidently belonging to the genus Arius, differing however from all known species of that genus. They therefore represent a new species, which I now describe under the name of Arius Bleekeri in honour of the great Ichthyologist, who collected them. The systematic position of this new species is between the two East Indian Arius macronotacanthus Blkr. and Arius coelatus Val. After having described it, I will compare my Arius Bleekeri with these two well-known forms.

A new species, Asplenium riswanii (sect. Thamnopteris), is described from Central Java and West Papua, Indonesia. It is distinct from any known species by having thick and rigid fronds, abaxially keeled midribs, broadly lanceolate scales, and distantly spaced sori. Morphologically, A. riswanii is not similar to any species from Malesia but somewhat close to A. antrophyoides from mainland Southeast Asia. Molecular data reveal it has an isolated position in the phylogeny. The micromorphology of spores and leaf epidermis of A. riswanii is also documented and a key to the species of Asplenium sect.

A new species of Austrolebias Costa (Cyprinodontiformes: Rivulidae) from northeastern Uruguay, with comments on distribution patterns
Provedor de dados: Neotropical Ichthyology
Autores: Loureiro,Marcelo; Duarte,Alejandro; Zarucki,Matías.
A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin) and río Yaguarón (Patos-Merín system). The new species can be differentiated from all other species of the genus by the unique presence in males of uniform bluish gray pigmentation on flanks (without vertical bands) and unpaired fins. The new species is also distinguished by the combination of characters associated with a reduction of the squamation of the abdominal, preopercular, and opercular regions. The new species presents some morphological characteristics similar to A. gymnoventris and A. luteoflammulatus. The distribution of the new species is concordant with three other species of Austrolebias and may represent a case of drainage...

Autores: Sokolowicz,Carolina C.; Araujo,Paula B.; Boelter,Juliana F.
A new species of Benthana Budde-Lund, 1908 is described from southern Brazil. Benthana cairensis sp. nov. is distinguished from the other species in the genus by having 17 aesthetascs on the antennula and the elongated male pleopod 1 exopod with a lobe on the inner lateral margin and up to six setae on the outer lateral margin. The new species most resembles B. olfersii (Brandt, 1833), but may be distinguished by lacking the lobe with six setae on the internal margin of the proximal extremity of the merus of pereiopod 7. Furthermore, we include B. olfersii in the subgenus Benthanoscia based on the examined material as described herein.

A new species of Biemna (Porifera, Poecilosclerida) from the Sultanate of Oman
Provedor de dados: Naturalis Digital Academic Repository
Autores: Soest, R.W.M. van; Beglinger, E.J.
Recent (1998) collecting off the coasts of Oman in the course of the EC-MAS3 funded ‘Symbiosponge’ project yielded three species of the genus Biemna Gray, 1867 (Demospongiae, Poecilosclerida, Mycalina, Desmacellidae) not previously known from the area. One of these appeared to be new to science and is described as Biemna omanensis n.sp.. Its distinguishing features comprise the possession of oxea megascleres, which is of rare occurrence in Biemna, and a full complement of microscleres including microxeas, sigmas, commata, all of which are divisible in two non-overlapping size categories, and raphides. One of the other two species conformed to an earlier described species Biemna ciocalyptoides Burton, 1959, which was discovered to be a junior synonym of...

A second inseminating species bearing club cells organized into an anal-fin gland in sexually active males belonging to the genus Bryconadenos was recently discovered in the rio Xingu drainage and is described as new. It is distinguished from B. tanaothoros by the presence of a conspicuous dark blotch at the humeral region, and fewer scale rows between dorsal-fin origin and anal-fin origin. Males of B. weitzmani have longer pelvic fins at sizes beyond 30 mm SL. Bryconadenos weitzmani is further distinguished from B. tanaothoros by the cup shape of the anal-fin gland, its lower part much more developed than the upper, whereas in B. tanaothoros there is just a slit separating the almost equally developed upper and lower parts.

ABSTRACT A new species of the genus Bryconops , subgenus Bryconops , is described from the rio Conceição, a tributary to the rio Palma, upper rio Tocantins drainage, Tocantins State, Brazil. The new species is distinguished from all its congeners, except B. humeralis and B. vibex by the color pattern in vivo (dorsal, adipose, and caudal fins entirely orange). The new species is easily distinguished from B. humeralis and B. vibex by the absence of a humeral spot and by the lack of maxillary teeth (vs . presence of a single humeral spot and presence of 1-3 maxillary teeth on both sides). Furthermore, the new species is distinguished from B. vibex by the number of perforated lateral line scales (38-41 vs. 44-46).

A new Brazilian Calomys Waterhouse, 1837 species is described based on morphologic and karyologic data. This species is endemic to the Cerrado of Central Brazil and allopatric with all other species of the genus Calomys. Its chromosome complement (2n = 46, AN = 66) is different from those described in other Calomys species. Morphometric analysis significantly distinguished this new species from other Calomys of the Brazilian fauna like C. callosus (Renger, 1830), C. expulsus (Lund, 1841) and C. tener (Winge, 1887) and placed it among the large-sized Calomys.

A new species of Copionodon lacking a free orbital rim (Siluriformes: Trichomycteridae)
Provedor de dados: Neotropical Ichthyology
Autores: Pinna,Mario de; Burger,Rafael; Zanata,Angela Maria.
ABSTRACT A new species of the copionodontine genus Copionodon is described from the upper reaches of a tributary to the rio Paraguaçu in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known. The new species can be readily recognized by its large eye without a free orbital rim. Other characters such as the entirely cartilaginous second hypobranchial, and the uniformly broad irregular midlateral dark band further diagnose the new taxon. Its particular combination of characters is superficially intermediate between Copionodon and Glaphyropoma. Detailed analysis, however, indicates that it forms a monophyletic group with species of Copionodon and therefore it should be included...

A new species of Corynespora
Provedor de dados: Naturalis Digital Academic Repository
Autores: Loerakker, W.M.
In the course of investigations on fungi occurring on bark of deciduous trees, an unknown dematiaceous fungus was encountered. Because of its long, septate conidia, arising from the apex of dark conidiophores, the specimen was thought to represent an undescribed species of the genus Corynespora Güssow. This identification was kindly confirmed by Dr. M. B. Ellis, C. M. I., Kew.

A new species of Curculionichthys (Siluriformes: Loricariidae) from the north edge of the Brazilian Shield, lower Amazon basin
Provedor de dados: Neotropical Ichthyology
Autores: Gamarra,Suelen P.; Calegari,Bárbara B.; Reis,Roberto E.
ABSTRACT A new species of Curculionichthys is described from the rio Curuá-Una basin, in the northern edge of the Brazilian Shield, State of Pará, Brazil. The new species is diagnosed from congeners by possessing a single rostral plate, by having darkened tooth-crowns, and by a series of morphometric and meristic data. A close examination of the species of Curculionichthys revealed the presence of hyperthrophied odontodes on both dorsal and ventral margins of the snout tip, which are illustrated by electronic microscopy. A discussion is provided on possible phylogenetic relationships of the new taxon. The new species is provisionally accessed as Least Concern (not threatened).

A new species of Demidospermus Suriano, 1983 is described from the gills of Auchenipterus osteomystax Miranda-Ribeiro, 1918 (Auchenipteridae), collected in the upper Paraná river floodplain, Brazil. The gills were removed and preserved in 5% formalin. Later the parasites were removed from the gills with the aid of a stereomicroscope and conserved in 70% alcohol. Some specimens were stained with Gomori’s trichrome, dehydrated in absolute alcohol and cleared with faia creosote to observe the internal organs. Other specimens were mounted in Hoyer’s medium for the study of the sclerotized structures. The present study describes a new monogenetic species, Demidospermus osteomystax n. sp., characterized by: tandem gonads; V-shaped haptoral bars with...

Hemiancistrus cerrado has external similarities with H. megalopteryx and H. punctulatus from coastal streams of southern Brazil, and can be distinguished by having a larger internarial width, 15.9-21.1% of head length (vs. 11.2-14.0% in H. megalopteryx and 11.2-13.9% in H. punctulatus) and, with little overlap, by the larger adipose-fin spine length, 9.4-13.6% of standard length (vs. 7.1-8.7% in H. megalopteryx and 7.4-10.0% in H. punctulatus). Hemiancistrus cerrado further differs from H. megalopteryx by having the pectoral-fin spine reaching maximally to the middle of the pelvic-fin spine when adpressed in adult males (vs. reaching tip). Hemiancistrus cerrado...

A new species of Hemigrammus Gill, 1858 (Characiformes: Characidae) from the rio Madeira and rio Paraguai basins, with a redescription of H. lunatus
Provedor de dados: Neotropical Ichthyology
Autores: Ota,Rafaela P.; Lima,Flávio C. T.; Pavanelli,Carla S.
A new Hemigrammusis described from the rio Paraguai and rio Madeira basins, Mato Grosso and Rondônia States, Brazil. The new species is characterized by possessing a wide dark horizontal stripe across the eye, a vertically elongated humeral blotch, and 4-5 gill-rakers on upper branch and 9-10 on lower. The new species can be easily diagnosed from H. lunatus, the sympatric and morphologically most similar congener, by the shape of humeral blotch and the number of gill rakers. Data of the type material of both Hemigrammus lunatus and H. maxillaris, as well as extensive examination of specimens, allowed us to conclude that H. maxillarisis a junior subjective synonym of H. lunatus. A redescription of H. lunatus, as well as a formal restriction of its type...

A new species of Hyphessobrycon Durbin (Characiformes: Characidae) from the middle rio São Francisco and upper and middle rio Tocantins basins, Brazil, with comments on its biogeographic history
Provedor de dados: Neotropical Ichthyology
Autores: Dagosta,Fernando C. P.; Marinho,Manoela M. F.; Camelier,Priscila.
A new species of Hyphessobrycon Durbin is described from tributaries of the rio Grande (rio São Francisco basin) draining east to the Serra Geral de Goiás, of the rio São Domingos (upper rio Tocantins basin) and rio do Sono basins (middle rio Tocantins basin). Hyphessobrycondiastatos can be diagnosed from its congeners by the absence of humeral spot, 15-18 branched anal-fin rays, 1-3 maxillary conical to tricuspid teeth, a relatively well-defined dark caudal-peduncle spot, and elongation of dorsal- and anal-fin rays in mature males. The biogeographical significance of the distribution of the new species is evaluated and discussed.

In the last few years, however, members of both the Rijksherbarium and the Netherlands’ Mycological Society (N.M.V.) have been collecting more frequently on these islands. The results of their fieldtrips are promising for the future as many interesting and rare fungi have been found. In a previous paper (Noordeloos, 1975) I described a rare species of the genus Marasmiellus Murr., viz. M. caespitosus (Pat.) Sing. from the Island of Texel¹.

Autores: Calegari,Bárbara B.; Reis,Roberto E.
Microlepidogaster longicolla, new species, is described from the rio São João of the upper rio Paraná basin near Brasília, in central Brazil. The new species differs from M. perforatus, the only other species in this genus, by having a continuous lateral line, median lateral plate series reaching, rather than falling short of, the end of the caudal peduncle, a shorter pectoral-fin spine (13.4-16.2 vs. 18.2-21.0% standard length), a smaller interorbital distance (38.9-43.1 vs. 47.7-53.3% head length), and more numerous dentary teeth (16-29 vs. 12-15), in addition to several osteological features. Microlepidogaster longicolla shows a remarkable suite of secondary sexually dimorphic characters, involving the presence of a conical urogenital papilla in males,...

Autores: Dagosta,Fernando C. P.; Marinho,Manoela M. F.
ABSTRACT A new species of Moenkhausia is described from the rio Arinos drainage, rio Tapajós basin, Mato Grosso, Brazil. The new species is diagnosed from all congeners, except M . hemigrammoides , M . nigromarginata , and Moenkhausia rubra by having intense diffuse dark pigmentation on the dorsal and anal fin-rays. The new species can be distinguished from the above mentioned species by the combination of 20-23 branched anal-fin rays, presence of a vertically elongate roughly rectangular humeral spot surpassing the lateral line ventrally, absence of a well-defined black spot on the distal portion of the dorsal fin and lack of a series of longitudinal dark zigzag stripes on body. The new species is herein described along with a report and discussion of a...

Provedor de dados: Revista Brasileira de Zoologia
Autores: Mendonça,Maria Cleide de; Queiroz,Gabriel Costa.
A new species of Collembola, Mucrosomia alticola sp. nov., is described and illustrated based on material from "Parque Nacional da Serra dos Órgãos" (State of Rio de Janeiro) and from "Parque Nacional da Serra do Caparaó" (State of Minas Gerais). This is the first record of a species of Mucrosomia for Brazil. The genus has, up to date, only three species and can be diagnosed by the absence of eyes and pigmentation, PAO present, tenent hair pointed, Abd V and VI fused, manubrium with 1+1 chaetae on anterior side, long dens and a remarkable mucro with five teeth. The presence of chaetae on ventral thorax, between segments II-III, supports the new species.

INTRODUCTION Hitherto only one species of Nevskyella Ossiannilsson, 1954, was known, viz., the type, Nevskya fungifera Ossiannilsson, 1953. This has only been found near Uppsala, Sweden on Carex caryophyllea Latour ( = C. verna Chaix = C. praecox Jacq.). A very similar species found in three departments of southern France is described hereafter. Nevskyella meridionalis nov. spec. Apterous viviparous female. Morphological characters. — Body about 1.35 to 1.80 mm long, elongated oval, often quite slender, not depressed. Pigmentation of body very nearly like that figured by Ossiannilsson (1935, p. 235, fig. 1) for the type species, but usually the meso-metathoracic blotches extended more cephalad and often connected with the blotches of the pronotum; the...

Autores: Garcia-Ayala,James R.; Benine,Ricardo C.
ABSTRACT A new species of Poptella is described from the Rio Juma, a tributary of the lower Rio Aripuanã, Rio Madeira basin, Amazonas, Brazil. The new species is distinguished from all congeners, except P. brevispina, by having a lower number of scale rows between the lateral line and dorsal-fin origin (7 vs. 8-10). The new species can be readily distinguished from P. brevispina by the lower number of branched dorsal-fin rays (9 vs. 10). This is the first description of a new species of Poptella since the revisionary study of the Stethaprioninae, published 30 years ago.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Matos Nogueira, João Miguel de; Garraffoni, André Rinaldo Senna; Montrezoro Alves, Tarsila.
A new species of Streblosoma is described and the diagnosis of S. oligobranchiatum is emended, based on material collected on intertidal rocky shores along the State of São Paulo, Brazil, associated with algae, sponges, ascidians and other sedentary polychaetes. Streblosoma porchatensis n. sp. is characterised by the C-shaped arrangement of uncini from posterior thorax, numerous branchial filaments, some inserted laterally from the level of notopodia on segment 2, and by the morphology of uncini. The diagnosis of S. oligobranchiatum is emended to allow for variation in the number of branchial filaments and dental formula of uncini. Both species are compared with the closest congeners and some comments are made on the relationships within the group.

During soil fauna investigations performed in 1959 by Dr. J. van der Drift (see his study, 1963), three specimens were collected of a small coleopteroid heteropteron, representing a new species belonging to the genus Thaumamannia Drake &amp; Davis, 1960. Up till now, only one other species in this genus was known, viz., T. manni, collected in an ants' nest by Mr. W. H. Mann in Bolivia. The other three known species in the subfamily Vianaidinae1) belong to the genus Anommatocoris China, 1945, and are also found with ants (Drake &amp; Ruhoff, 1965). The new species described here is closely related to the Bolivian species, and in all likelihood is also myrmecophilous.

A new armored catfish species of the genus Pareiorhaphis is described from the middle and upper portions of rio Paraguaçu basin, coastal drainage of Bahia State, northeastern Brazil. The new species is readily distinguished from all its congeners by having two putative autapomorphies: (1) skin fold just posterior to each emergent tooth series of dentary formed by a single enlarged, flattened papilla, and (2) the midline of lower lip immediately behind the dentaries with small patch of distinct papillae arranged in a short median bump. In addition, the shallow caudal peduncle and comparatively lower number of teeth in each dentary also distinguishes the new species from all congeners. The new species is also compared to Pareiorhaphis bahianus, the...

The new species Roscidotoga lamingtonia is described, a leafminer on Sloanea woollsii (Elaeocarpaceae) from the subtropical rainforests of Lamington National Park, southern Queensland, and Border Ranges National Park, New South Wales. R. callicomae Hoare, 2000 is recorded for the first time from Queensland, and from Lamington National Park. These records fall within the genus’ limited range in the rainforests in eastern Australia. R. lamingtonia is the second species of the  genus feeding on Elaeocarpaceae. On the basis of a few possible apomorphies we hypothesize one host-shift from Cunoniaceae to Elaeocarpaceae. DNA barcodes for R. lamingtonia and R. callicomae are given.

A new species of the genus Linuparus (Crustacea, Palinuridae) from South-East Africa
Provedor de dados: Naturalis Digital Academic Repository
Autores: Berry, P.F.; George, R.W.
INTRODUCTION The genus Linuparus White was recently reviewed by Bruce (1965) who gave an excellent account of two species, the type species L. trigonus (Von Siebold) and a previously undescribed species L. sordidus Bruce from the South China Sea. George &amp; Main (1967) reviewed the family Palinuridae and suspected that "four geographically isolated species are probably represented within the recorded distribution of Linuparus; one in Japan (trigonus), one in South China sea (sordidus), one off Portuguese East Africa. .. and one off east Australia...". During 1970, when one of us (R.W.G.) visited the Oceanographic Research Institute at Durban, the opportunity was taken by us to assemble relevant specimens of Linuparus for comparison and review of that...

A new species of the genus Linuparus White, from the South China Sea (Crustacea Decapoda)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bruce, A.J.
The palinurid genus Linuparus White, 1847, has been represented by a single recent species, Linuparus trigonus (Von Siebold). The trawl survey of the northern shelf region of the South China Sea at present being carried out by the R.V. "Cape St. Mary" of the Fisheries Research Station, Hong Kong, has produced numerous examples of this species. Amongst old collections of Crustacea at the Fisheries Research Station, a single example of a specimen of Linuparus was found early in 1963, which showed numerous differences from the specimens obtained on the trawl survey. This specimen lacked data and was badly damaged, making a full comparison with Linuparus trigonus impossible. In January 1964, a second specimen was obtained which confirmed the constancy of the...

&lt;i&gt;Pontocypria coriocellae&lt;/i&gt; sp. n. is described from Papua New Guinea. The species was found inside the oral tube near the radula, of &lt;i&gt;Coriocella nigra&lt;/i&gt; Blainville, 1824 (Gastropoda, Prosobranchia, Lamellariidae). Because of its morphology and its mode of life, the new species may be considered as an occasional commensal of its gastropod hosts. It is the first &lt;i&gt;Pontocypria&lt;/i&gt; species to be found inside its host. The distribution of the genus &lt;i&gt;Pontocypria&lt;/i&gt; is discussed.

Autores: Jentink, F.A.
This beautiful greenish tinged Squirrel has been procured by Mr. G. J. A. Pool at the Stanley-falls, Congostate, in August 1905; Professor Dr. A. A. W. Hubrecht (Utrecht) had the kindness as to present it to our National Museum. It apparently is an animal belonging to a hitherto undescribed species; I describe it here under the specific title of the collector: Sciurus Poolii, n. sp. It is a wood-squirrel, known by the indigenes under the name Pania ya mti (Kiswahili-dialect), rather frequent, eaten by the Negros (observations made by Mr. Pool).

A new starting point for the South and Equatorial Atlantic Ocean
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Moulin, Maryline; Aslanian, Daniel; Unternehr, Patrick.
The opening of the Equatorial and South Atlantic Oceans is still a matter of debate, particularly as concerns the locations of the intraplate deformation. We propose here a critical review of the kinematic models published since Bullard et al., 1965, based on a series of constraints: new interpretation of the magnetic anomalies, seafloor isochrons, flow lines, fracture zones, continental and oceanic homologous structures and radiometric dating of igneous rocks. All of these models present numerous unexplained misfits (gaps, overlaps and misalignments). We present here a new evolution of the Equatorial and South Atlantic Ocean from the tightest reconstruction to Chron C34. This new model confirms the hypothesis of a northward propagation of the South...

A New Statistical Method for Comparative Anatomy
Provedor de dados: International Journal of Morphology
Autores: Aversi-Ferreira,Tales Alexandre.
Rules, formulas and statistical tests have been widely used in studies that use continuous variables in the normal or Gaussian distribution or other tests whose data fit this type of distribution (t and z distributions) and whose parameters can be defined. However, there are cases in which the model and goal of the scientific work allow only the use of discrete or nominal variables. The absence or presence of a structure or organ (muscles, nerves, blood vessels, bones, and ligaments), characteristics associated with these organs, such as the source of nerves, vessels and muscles and the distribution of nerves and vessels are discrete and / or nominal variables that do not fit the Gaussian distribution, nor of z or t, unless the measures of these structures...

A new stem fossil characid (Teleostei: Ostariophysi) from the Eocene-Oligocene of southeastern Brazil
Provedor de dados: Neotropical Ichthyology
Autores: Weiss,Fernanda E.; Malabarba,Maria Claudia; Malabarba,Luiz R.
A new characiform is herein described from the Eocene-Oligocene sediments exposed in the Aiuruoca basin, in southern Minas Gerais State, Brazil. Recently, two other characid species were described for this same fossil level: †Paleotetra aiuruoca and †Paleotetra entrecorregos. The holotype of this new characiform is represented by an articulated specimen preserved as part and counterpart, in which the most anterior part of the head is missing, including the jaws. Despite the lack of the diagnostic characters from the snout, a unique combination of characters allows its differentiation from other Neotropical characiforms, raising a new genus and species: †Bryconetes enigmaticus. Among these characters are: the presence of a supraorbital, dentary with...

A new study method of microhabitat structure of small mammals
Provedor de dados: Brazilian Journal of Biology
Autores: CERQUEIRA,R.; FREITAS,S. R.
The variables in habitat studies are usually transformed in such a way that they become abstractions and intuition is lost. We tested a new method for the analysis of habitat using data collected in a grid laid at the "restinga de Maricá", in Rio de Janeiro State, Brazil. Thirty-seven microhabitat variables were measured at each trap station. We assume that these variables characterize the microhabitat structure at the moment when measurements were taken. The data are transformed in 3 ways: (1) the averages of the measured variables were calculated, as usual in habitat studies; (2) the data are transformed in densities per area in square meters without reduction in the number of variables; and (3) we calculated the natural logarithms of the data thus...

In his paper on “Scorpions” from Curaçao, Aruba, Bonaire and the Venezuelan Islands, WAGENAAR HUMMELINCK (Stud. fauna Cur. 2, 1940, p. 141) drew attention to the fact that specimens of Rhopalurus hasethi from the island of Aruba possess, on the average, four pectinal teeth less than specimens from Curaçao, the island from which the species was originally described. Lack of time and material prevented this author from paying full attention to other differences. He confined himself to giving a small table, in which the following numbers of pectinal teeth were reported, without a distinction being made between males and females.

Autores: Hédl, R.; Svátek, M.; Dančák, M.; Rodzay, A.W.; Salleh, M.A.B.; Kamariah, A.S.
This paper describes a new technique for inventory of permanent plots in tropical forests and presents the results of its application in a 1 ha permanent plot in a lowland dipterocarp forest at Kuala Belalong, Ulu Temburong National Park, Brunei Darussalam. The technique is based on mapping of positions of tree individuals in three-dimensional space with a high accuracy. Measuring set consists of a distance measuring device (laser rangefinder) and a electronic compass supplying data to a field computer with specialized software (Field-Map®). This method is faster and more exact than methods based on Cartesian grids established in the field. As an example, inventories from 2000 and 2007 of the plot mentioned are compared concerning presence, taxonomical...

Autores: KELLNER,ALEXANDER W.A.; WEINSCHÜTZ,LUIZ C.; HOLGADO,BORJA; BANTIM,RENAN A.M.; SAYÃO,JULIANA M.
Abstract Abstract: The first pterosaur bone bed from Brazil was reported in 2014 at the outskirts of the town Cruzeiro do Oeste, Paraná State, in the Southern region of the country. Here named 'cemitério dos pterossauros' site, these outcrops were referred to the Goio-Erê Formation (Turonian-Campanian) of the Caiuá Group (Bauru Basin) and revealed the presence of hundreds of isolated or partially articulated elements of the tapejarine pterosaur Caiuajara and fewer amounts of a theropod dinosaur. Here we present a new tapejaromorph flying reptile from this site, Keresdrakon vilsoni gen. et sp. nov., which shows a unique blunt ridge on the dorsal surface of the posterior end of the dentary. Morphological and osteohistological features indicate that all...

In September 1981, seeds of Arisaema were harvested by Carla Teune, Hortus Botanicus Leiden, near Liuba, area of Mt Minya Konka (Gonga Shan), Szechuan (Sichuan) Province, China, at 3600 m altitude. During the trip, with Roy Lancaster and others, no pressed herbarium specimen was collected. Michael Hoog, who runned a well known Dutch Nursery, was given five lots of seed numbered CT 368 to CT 372, all provisionally labeled A. consanguineum Schott. All numbers were collected the same day along the same path. After the seedlings flowered, it appeared there was no reason to keep them separate; they were merged and distributed in the trade as Arisaema CT 369 (Antoine Hoog, 1998, private communication).

A new variety of Sarcotheca Laxa (Oxalidaceae) from Sumatra
Provedor de dados: Naturalis Digital Academic Repository
Autores: Veldkamp, J.F.
In 1985 during the Fourth Expedition to S Aceh, Sumatra, in the neighbourhood of the G. Leuser National Park a representative of Sarcotheca (Oxalidaceae) was collected. It clearly is a member of the S. laxa complex previously known only from Malaya and the Riouw Archipelago. It differs from all by the golden puberulous, soon glabrescent innovations, the thicker, broader, more ovate leaflets, and the structure of the inflorescences (short, slender, subequally branched). In the technical characters it seems closest to var. sericea (Ridley) Veldk., but it differs by the leafblades with fewer pairs of nerves, the sparsely white puberulous inflorescence axes and branches (the hairs can easily be distinguished separately and seem longer), the pedicels with the...

A new Vitex from Malaysia
Provedor de dados: Naturalis Digital Academic Repository
Autores: Lam, H.J.; Meeuse, A.D.J.
In 1919 Dr C. A. BACKER collected a plant in the Kangean Archipelago which had the appearance of a Cymaria so that the collector provisionally called it ”Cymaria triphylla BACKER“ (MS.). The same species was also collected by KARTA on the Island of Bawean in 1928. Some other sheets already extant in the Herbarium at Buitenzorg for a long time among the indeterminate specimens were recognized as identical with this ”Cymaria“ (TEYSMANN nr. 1750, Madoera and nr. 1768, Bawean). In 1937 Dr BACKER, when working up Javanese plants, had a closer examination of this plant and concluded that it could not be inserted in Cymaria, and even not in the Labiatae, but that it had rather to be put into the Verbenaceae. However, he found himself unable to identify the...

A new world natural vegetation map for global change studies
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Lapola,David M.; Oyama,Marcos D.; Nobre,Carlos A.; Sampaio,Gilvan.
We developed a new world natural vegetation map at 1 degree horizontal resolution for use in global climate models. We used the Dorman and Sellers vegetation classification with inclusion of a new biome: tropical seasonal forest, which refers to both deciduous and semi-deciduous tropical forests. SSiB biogeophysical parameters values for this new biome type are presented. Under this new vegetation classification we obtained a consensus map between two global natural vegetation maps widely used in climate studies. We found that these two maps assign different biomes in ca. 1/3 of the continental grid points. To obtain a new global natural vegetation map, non-consensus areas were filled according to regional consensus based on more than 100 regional maps...

In his paper on the peat swamp forests of Sarawak and Brunei (Gard. Bull. 20, 1963, 152) Dr. J. A. R. Anderson made notice of a distinctive Xanthophyllum species which he was not able to identify. In 1968, Mr. F. S. P. Ng, revising the genus for the Manual of Malayan Timber Trees, recognized it as a new species, but did not describe it. Working now on a monograph of the genus, and having examined all collections Dr. Anderson kindly sent on loan to me, I am able to describe it here as a new species. I am much indebted to Dr. H. Sleumer for rendering the diagnosis in Latin.

Autores: McAdams,   Callie P.; Palma,   Marco A.; Ishdorj,   Ariun; Hall,   Charles R.
A preference and valuation mechanism that compared results of an experimental auction and nonhypothetical preference rankings was developed and used to elicit preferences for pomegranate products from a representative sample of shoppers in Texas.  Familiarity with pomegranate products increased willingness-to-pay (WTP) for pomegranates, as did tasting and providing additional information on the health benefits of the products.  Ready-to-eat and juice products were preferred to whole fruit products.  Subjects did not indicate an increased WTP for Texas varieties over California Wonderful pomegranate based on auction bids but indicated a preference for one Texas variety in the nonhypothetical ranking procedure; thus, the auction results and nonhypothetical...

A Nonlinear Offset Program to Reduce Nitrous Oxide Emissions Induced by Excessive Nitrogen Application
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rosas,   Francisco; Babcock,   Bruce A.; Hayes,   Dermot J.
On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative environmental consequences because the nitrogen that is not taken up by the plant will typically volatilize causing N2O emissions, or leach causing water pollution. We present a nonlinear offset program that induces farmers to reduce their nitrogen applications to the level that will be consumed by the plant in a typical year and, as a result, reduce N2O emissions from agriculture. The offset program is nonlinear because of the nonlinear relationship between N2O...

A non-linear viscoelastic viscoplastic model for the behaviour of polyester fibres
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chailleux, Emmanuel; Davies, Peter.
In this study the macroscopic analysis proposed by Schapery has been applied to model the non-linear viscoelastic and viscoplastic behaviour of polyester fibres. First, a special non-contact extensometry method has been developed in order to measure the fibre response without affecting the behaviour of these extremely anisotropic fibres. An accelerated identification method has then been developed. This enables a unique and independent set of parameters to be determined, which separate the reversible and non-reversible mechanisms responsible for measured strains. The model prediction for an arbitrary loading sequence corresponds closely to the measured strains. The model has been applied here at the yarn level but can equally well be used to predict rope...

Autores: Moen,   Daniel S.; Capps,   Oral, Jr.
Nonparametric statistical methods (the Kruskal-Wallis test and Dunn's multiple comparison procedure) were used to analyze consumer preferences for fresh meat products (chicken, beef steak, beef roast, fish, ground beef, pork, turkey, and lamb) in a retail food chain in Houston. On a pairwise basis, significant differences in ratings were evident for the majority of the fresh meat products in terms of frequency of purchase as well as taste and quality. In particular, chicken was not only the most frequently purchased fresh meat product but also compared favorably to all meat items in terms of taste and quality.

A non-randomized comparative study using different doses of acyclovir to prevent herpes simplex reactivation in patients submitted to autologous stem cell transplantation
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Atalla,Angelo; Maiolino,Angelo; Guimarães,Maria Angélica; Guimarães,Antonio Carlos; Nucci,Marcio.
The reactivation of Herpes Simplex virus (HSV) occurs in 70% to 80% of patients submitted to autologous stem cell transplantation (ASCT); it increases the severity of chemotherapy-induced mucositis. Therefore, the use of acyclovir in ASCT patients is considered standard practice. However, the minimum dose needed to prevent reactivation is a matter of debate. We compared two doses of acyclovir in a non-randomized fashion in 59 patients submitted to ASCT: 32 patients received a dose of 125 mg/m² IV every six hours and the subsequent 27 patients received a dose of 60 mg/m² IV every six hours. Viral excretion was evaluated through weekly viral culture of oral swabs. Grade 4 mucositis was more frequent in Group 1 (p= 0.03). The reactivation rates in Groups 1...

A normalization technique for next generation sequencing experiments

Autores: G&amp;#xfc;nter Klambauer; Karin Schwarzbauer; Andreas Mayr; Sepp Hochreiter.
Next generation sequencing (NGS) are these days one of the key technologies in biology. NGS&amp;#x27; cost effectiveness and capability of finding the smallest variations in the genome makes them increasingly popular. For studies aiming at genome assembly, differences in read count statistics do not affect the outcome. However, these differences bias the outcome if the goal is to identify structural DNA characteristics like copy number variations (CNVs). Thus a normalization step must removed such random read count variations subsequently read counts from different experiments are comparable. Especially after normalization the commonly used assumption of Poisson read count distribution in windows on the chromosomes is more justified. Strong deviations of...

Building chronological frameworks for proxy sequences spanning 130-60 ka b2k is plagued by difficulties and uncertainties. Recent developments in the North Atlantic region, however, affirm the potential offered by tephrochronology and specifically the search for cryptotephra. Here we review the potential offered by tephrostratigraphy for sequences spanning 130-60 ka b2k. We combine newly identified cryptotephra deposits from the NGRIP ice-core and a marine core from the Iceland Basin with previously published data from the ice and marine realms to construct the first tephrostratigraphical framework for this time-interval. Forty-three tephra or cryptotephra deposits are incorporated into this framework; twenty three tephra deposits are found in the...

Autores: Parsons,   Robert L.; Hanson,   Gregory D.
A financial training program designed by Cooperative Extension specialists was provided to over 2,000 USDA/FSA borrowers from the Northeast during the period 1994-1999.  Key to the success of the workshops was an in-depth, user-friendly curriculum that evolved over time, eventually replacing satellite-feed instruction with pre-taped videos.  Cluster analysis classified nearly 70 percent of workshop participants as "Low Finance Priority" or "Low Finance Knowledge."  Farmers in these clusters received a relatively greater educational benefit from the program than those not in these clusters..   Impact analysis indicated that perceived annual gain in farm net worth from application of workshop tools ranged from approximately $5,000 to $10,000.  The training...

Autores: Sluiman, H.J.
From 1936 on E. Post has published a series of studies concerning the taxonomy, the ecology, and the geographical distribution of the algae of the so-called Bostrychia-Caloglossa association or Bostrychietum. In this association species of Bostrychia, Caloglossa, Catenella, Murrayella (all Rhodophyta) and other algal genera are involved. Though the Bostrychietum is usually found on aerial roots of mangroves in the upper part of the littoral belt in the tropics, the association is represented also by reduced numbers of species in sheltered habitats in temperate regions. In Post’s monograph on the Bostrychia-Caloglossa association (1936) the number of known species of the genus Bostrychia Montagne in De la Sagra 1842 was reduced from about 50 to 13. In later...

Autores: Cook,   Steven.
The recently examined durability-asymmetry hypothesis of Cook (1999) is re-evaluated using the diagnostic tests of time deformation proposed by Stock (1987, 1988). An application of these tests to disaggregated data on U.S. consumers’ expenditure provides further support for this hypothesis, with the findings given an economic interpretation in terms of variables evolving at differing speeds over different phases of the business cycle. Additionally, building upon the studies of Cover (1992), Karras (1996) and Rhee and Rich (1995), recent research by Arden et al. (2000) has shown the relaxation of the assumptions of linearity and symmetry typically employed in macroeconometric models to result in monetary policy having clear asymmetric effects on the...

A NOTE ON FORECASTING WITH ECONOMETRIC MODELS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Allen,   P. Geoffrey.
Forecasts made by econometricians are typically conditioned on actual values of explanatory variables, even when at the time of the forecast, such variables might not be available.  As a first step, one might test the adequacy of econometric specification by comparing conditional post sample forecasts with those of a univariate ARIMA model.  Second, when explanatory variables must themselves be forecast, those for which this can be done only badly, should be omitted from the final model.  A better forecast will result.  An example of screening out badly forecasted explanatory variables is presented.

For tomatoes, potatoes, carrots and onions in the Sydney market, the degree of variability of the retail price is substantially lower than the degree of variability of the wholesale price. The objective here is to investigate whether fresh vegetable retailers in the Sydney market practice price levelling and price averaging. 2SLS and 3SLS procedures were used to estimate a system of price spread equations for the four vegetables using quarterly data from 1980 to 1990. In the preferred 3SLS estimates price levelling was confirmed for potatoes and carrots. Price levelling was not evident in the tomatoes and onions equations, with price transmission influenced more by markup pricing policies for these vegetables. No evidence of price-averaging behaviour was...

A series of measures of temperature and salinity was made in different brackish waters along the Atlantic coast of Morocco. All waters examined were polyhaline, except for a series of hyperhaline salt mines. The importance of temperature in the sediment is discussed: temperature in the top layer may rise considerably (7° C) above air temperature. However, in the deeper layers, temperature is lower than in the air and the water.

A note on stomatal types and crystals in the leaves of Melastomataceae
Provedor de dados: Naturalis Digital Academic Repository
Autores: Baas, P.
Original data on leaf crystals and stomatal types in 25 genera of Melastomataceae are presented, and discussed with reference to the classification of the family as modified by Van Vliet et al. (1981, this issue). The heterogeneity of the abolished subfamily Astronioideae is confirmed and a separation of Pternandra from the Astronieae is also justified on the basis of leaf anatomical data. The Astronieae are characterized by large styloids and predominantly anomocytic stomata; this combination of characters also occurs in part of the Melastomatoideae (especially the Miconieae). Most other Melastomatoideae are characterized by polocytic to diacytic stomata and druses. The subfamilies Memecyloideae and Crypteronioideae remain rather heterogeneous leaf...

A Note on the Appropriate Measure of Tax Burden on Foreign Direct Investment to the CEECs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bellak,   Christian; Leibrecht,   Markus; Romisch,   Roman.
In this note we show that tax-rate elasticities of Foreign Direct Investment (FDI) to Central and East European Countries (CEECs) derived from statutory corporate income tax rates (STRs) are likely to be flawed. From a conceptual point of view STRs are problematic as they neither capture tax base effects, nor effects of the home country, the international or the supranational tax laws on the corporate tax burden. Concerning FDI, from an empirical point of view STRs are questionable as their behavior over time and between country-pairs may be very different from that of the conceptually superior bilateral corporate effective average tax rates (BCEATRs). We compare the variability of STRs and BCEATRs of seven major home countries of FDI in eight major CEEC...

Program concord implements L. I. Lin’s concordance correlation coefficient (Lin 1989), as well as the limits-of-agreement procedure (Bland and Altman 1986). Recently, Lin (2000) issued an erratum reporting a number of typographical errors in his seminal 1989 paper. Further, changes in Stata Version 7 required modification of concord. This note reports the effect of the errors and provides a corrected and updated program.

A Note On The Denisova Cave mtDNA Sequence
Provedor de dados: Nature Precedings
Autores: Niccolo Caldararo; Michael Guthrie.
The recently published Altai fossil sequence from Denisova Cave was purported to be so different from anatomically modern humans, yet have the physiological landmarks of that species designation. When the published sequence was examined it was found that segments in the mtDNA hypervariable regions could be found to align with that of anatomically modern humans if one introduced an insertion at a position found in Neanderthals. Some other points of interest arise from a reconsideration of the sequences for other published samples and Neanderthals from the same perspective.

Bats of the genus Artibeus are among the most important seed dispersers in early successional forests. We report observations on the foraging behavior of Artibeus lituratus in Pedra da Cebola Municipal Park, an urban park in the city of Vitória, Espírito Santo, southeastern Brazil. Observations were made during six consecutive days (April 1st to April 6th, 2006). Three mist-nets were opened each night close to a Maclura tinctoria tree (Moraceae), remaining open from 18:00 to 22:00, totaling four hours per night, and 24 hours of sampling effort. We observed two peaks of feeding activity at the tree, one between 18:20 and 19:30, and a second one at 21:00. This is the first observation of Artibeus lituratus feeding on M. tinctoria fruits, therefore adding a...

A NOTE ON THE EFFICIENCY OF INCOME REDISTRIBUTION WITH SIMPLE AND COMBINED POLICIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bullock,   David S.; Salhofer,   Klaus.
Recent studies have investigated the efficiencies of policies that use several policy instruments simultaneously (for example, a policy that uses a production subsidy combined with a production quota).  Several studies of very specific cases find that optimal combination of two policy instruments is more efficient than optimal independent use of either.  In this note we demonstrate using set theory and maximization theory, that all such specific results are examples of a more general result, which is that by combining m instruments efficiently, a government can always be at least as efficient as when using a subset of those m instruments.  This result holds for any of the several definitions of "efficiency" in the literature.

A Note on the Equilibrium Properties of Locational Sorting Models
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bayer,   Patrick; Timmins,   Christopher.
A central feature of many models of location choice – whether of firms or households, within or across cities – is the role of local interactions or spillovers, whereby the payoffs from choosing a location depend in part on the number or attributes of other individuals or firms that choose the same or nearby locations in equilibrium. The main goal of this paper is to develop the equilibrium properties of a broadly applicable and readily estimable class of sorting models that allow the location decision to depend on both fixed local attributes (including unobserved attributes) and such local interactions. In particular, we prove uniqueness in the case of congestion effects and use a series of simulations to demonstrate that a unique equilibrium is more...

A note on the genus Liocranium Ogilby (Pisces, Scorpaenidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Mees, G.F.
The genus Liocranium was established by Ogilby (1903) to contain a new species of scorpion-fish from the east coast of Queensland: L. praepositum. The genus remained monotypic until McCulloch (1921) placed Paracentropogan scorpio Ogilby in it, a species also described from the Queensland coast. Whitley (1933) did not agree, and transferred P. scorpio to a separate new genus Vadesuma. In the meantime Weber (1913) described as Paracentropogon pleurostigma and Paracentropogon cynocephalus two scorpion-fishes from the East Indies. These two species, however, were not well placed in Paracentropogon, and therefore De Beaufort (1949) created the genus Sibogapistus for them. Apart from McCulloch's (1921) remark that: "Paracentropogon cynocephalus Weber is perhaps...

A Note on the Reliability Tests of Estimates from ARMS Data

Autores: Kim,   C.S.; Hallahan,   Charles B.; Lindamood,   W.A.; Schaible,   Glenn D.; Payne,   James.
USDA uses the concept of "publish-ability" rather than statistical reliability of an estimate for quality validation of USDA estimates, which is solely based on the sample size and the coefficient of variation (CV). We demonstrate conceptually how the reliability of the sample mean can be tested by estimating the upper and lower bounds of the confidence interval for an unknown population mean using the CV. However, the reliability test for the sample mean can be made only under the normality assumption. USDA multiple-way Agricultural Resource Management Survey (ARMS) estimates are used to illustrate the relative measure of precision for sample-based estimators.

Autores: Schwassmann,H.O; Barthem,R.B; Carvalho,M.L.
To understand the hydrological and limnological conditions during the annual regime of high and low river flow, as well as the action of the tides, a series of 18 collecting trips were conducted in monthly and bimonthly intervals across the Bay of Marajó during the years 1983-1985. The Tocantins River provides more than 80% of the inflow into this bay and shows a much greater difference in water volume flow between high and low water season than the Amazon. The annual displacement of brackish water influence is thus more extensive Marajó Bay than in the Amazon estuary. During the dry season of low river discharge (September-December), traces of seawater are found to penetrate up to 90 km upriver in the Guamá River. The high degree of turbidity of inner...

As Capparis corymbosa Roxb. [Hort. Beng. (1814) 93 nom. nud. et Fl. Ind. 2 (1832) 569 ed. Carey] was a later homonym of Capparis corymbosa Lamk. (1785), an African plant, Decandolle in Prod. I (1824) 247—248 had proposed the new name of C. roxburghii for the former basing it on Roxburgh’s specimen in the Banks herbarium under the manuscript name of ‘C. aguba’. Incidentally, ‘aguba’ is also the vernacular name used by Roxburgh in his Flora Indica and this manuscript name was used only by Roxburgh before he described the species as Capparis corymbosa. De Candolle mentions of having seen a type specimen in the Banks Herbarium, now in the British Museum, but this specimen could not be traced.

Acute intermittent porphyria (AIP, OMIM 176000) is an autosomal dominant metabolic disease caused by mutations in the gene encoding hydroxymethylbilane synthase (HMBS; EC 4.3.1.8; formely named porphobilinogen deaminase, PBGD), mapped to chromosome 11q23.3. We describe a novel mutation of the HMBS gene, a de novo 3-base deletion in the splicing donor site of intron 3 (IVS3+2_4delTGG) in a woman affected by AIP. RT-PCR analysis revealed an abnormal HMBS mRNA, compatible with exon 3 skipping.

A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected in Yunnan, China. Cells were irregular cocci, about 0.9-1.02 µm×1.0-1.31 µm in the medium containing elemental sulfur and 1.5-2.22 µm×1.8-2.54 µm in ferrous sulfate medium. The ranges of growth and pH were 50-85 (optimum 65) and pH 1.0-6.0 (optimum 1.5-2.5). The acidophile was able to grow heterotrophically on several organic substrates, including various monosaccharides, alcohols and amino acids, though the growth on single substrate required yeast extract as growth factor. Growth occurred under aerobic conditions or via anaerobic respiration using elemental sulfur as terminal electron acceptor. Results of...

A novel alveolar Krebs cycle-triggered CO2 sensing mechanism regulates regional pulmonary ventilation.
Provedor de dados: Nature Precedings
Autores: Rainer Kiefmann; Paula Keller; Oliver Tritt; Kai Heckel; Sascha Tank; Martina Kiefmann; Leoni Schulte-Uentrop; Alwin Goetz.
Pulmonary perfusion disorders provoke atelectasis in order to minimize ventilation/perfusion mismatch. However, the underlying mechanisms remain unknown. Because intraalveolar CO2 concentration ([CO2]iA) declines as a consequence of poor pulmonary perfusion we postulated the existence a novel alveolar CO2-sensing mechanism which adapts the ventilation to perfusion. Real-time fluorescence imaging of rat lungs revealed that low [CO2]iA decreased cytosolic and increased mitochondrial Ca2+ in alveolar epithelial cells (AEC), leading to reduction of surfactant secretion and alveolar ventilation. Mitochondrial inhibition by ruthenium red or rotenone blocked the hypocapnia-induced responses. In cultured Type 2 AEC hypocapnia decreased cytosolic Ca2+ independently...

Background Schistosomiasis is the second-most widespread tropical parasitic disease after malaria. Various research strategies and treatment programs for achieving the objective of eradicating schistosomiasis within a decade have been recommended and supported by the World Health Organization. One of these approaches is based on the control of snail vectors in endemic areas. Previous field studies have shown that competitor or predator introduction can reduce snail numbers, but no systematic investigation has ever been conducted to identify snail microbial pathogens and evaluate their molluscicidal effects.

Abstract Osteogenesis imperfecta (OI) is genetically heterogeneous. Mutations in COL1A1 and COL1A2 are responsible for at least 90% of the cases, which are transmitted in an autosomal dominant manner or are de novo events. We identified a Thai boy with OI whose parents were first cousins. Because the proband was the product of a consanguineous marriage, we hypothesized that he might be homozygous for a mutation in a known gene causing a recessive form of OI. Using whole exome sequencing (WES), we did not find any pathogenic mutations in any known gene responsible for an autosomal recessive form of OI. Instead, we identified a COL1A1 frameshift mutation, c.1290delG (p.Gly431Valfs*110) in heterozygosis. By Sanger sequencing, the mutation was confirmed in the...

Bupropion is an antidepressant used in the treatment of smoking. The purpose of this study was to prepare controlled-release hydrogel films for buccal administration of bupropion and investigate its physicochemical and cytotoxic properties. The films were prepared from ultrapure sodium carboxymethylcellulose, hydroxypropylmethylcellulose K4M, and medium-viscosity chitosan. Evaluation of film physicochemical characteristics was based on scanning electron microscopy, bupropion content, mechanical strength (burst strength, relaxation, resilience, and traction), and cytotoxicity. Bupropion content in bilayer films was 121 mg per 9 cm2. The presence of bupropion modified film mechanical strength, but did not compromise the use of this pharmaceutical form. As...

A novel G21R mutation of the GJB2 gene causes autosomal dominant non-syndromic congenital deafness in a Cuban family
Provedor de dados: Genetics and Molecular Biology
Autores: Rabionet,Raquel; Morales-Peralta,Estela; López-Bigas,Núria; Arbonés,Maria Lourdes; Estivill,Xavier.
Deafness is a complex disorder affecting 1/1000 infants. In developed countries, more than 50% of deafness cases are thought to have a genetic cause. At least 40 loci for dominant non-syndromic deafness and another 30 for recessive non-syndromic deafness have been described. Mutations in the GJB2 gene are the cause of an important number of cases of non-syndromic recessive deafness but are not as common in non-syndromic dominant deafness cases. We describe here a new dominant mutation (G21R) in the GJB2 gene which causes deafness and has been identified in a three generation Cuban family with dominant non-syndromic congenital sensorineural profound deafness.

A NOVEL GREEN BIOREFINERY CONCEPT: Protein refining by lactic acid fermentation and biogas production from green biomass
Provedor de dados: Organic Eprints
Autores: Fernandez, Maria Santamaria.
The extraction of proteins from leaves, integrated in a green biorefinery, may represent an attractive solution to the increasing demand for protein-rich animal feeds while decreasing the dependency on soybean imports. Thereby such green biorefineries could contribute to the development of more self-sufficient and sustainable agricultural systems in Europe. The framework of this PhD study is a green biorefinery concept for the production of protein concentrate, biogas and fertilizer from organic and locally grown green crops like alfalfa, clover or grass. After the screw pressing of the fresh crops, lactic acid fermentation of the green juice with Lactobacillus salivarius BC 1001 was assessed as the key method for the recovery of proteins.

It is widely accepted that the classical constant-temperature hot-plate test is insensitive to cyclooxygenase inhibitors. In the current study, we developed a variant of the hot-plate test procedure (modified hot-plate (MHP) test) to measure inflammatory nociception in freely moving rats and mice. Following left and right hind paw stimulation with a phlogogen and vehicle, respectively, the animals were placed individually on a hot-plate surface at 51ºC and the withdrawal latency for each paw was determined simultaneously in measurements performed at 15, 60, 180, and 360 min post-challenge. Plantar stimulation of rats (250 and 500 µg/paw) and mice (125-500 µg/paw) with carrageenan led to a rapid hyperalgesic response of the ipsilateral paw that reached a...

Autores: Hussain, Mohamed Bakr; Laabir, Mohamed; Yahia, Mohamed Nejib Daly.
Copepods are excellent bioindicators of climate change and ecosystem pollution in anthropized coastal waters. This work reviewed the results of previous studies examining changes in egg production rate (EPR), hatching success (HS), and nauplius survival rate (NSR) in natural conditions and in the presence of pollutants, including heavy metals and organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs). At high concentrations, cadmium and silver induce an increase in EPR in the copepods Acartia tonsa and Acartia hudsonica, while exposure to mercury decreases EPR in adults by 50%. All three metals affect HS, with mercury inducing a stronger effect than cadmium and silver. Cadmium affects reproductive...

Autores: Sanchez, Wilfried; Burgeot, Thierry; Porcher, Jean-marc.
Multi-biomarker approaches are used to assess ecosystem health and identify impacts of environmental stress on organisms. However, exploration of large datasets by environmental managers represents a major challenge for regulatory application of this tool. Several integrative tools were developed to summarize biomarker responses. The aim of the present paper is to update calculation of the "Integrated Biological Response" (IBR) described by Beliaeff and Burgeot (Environ Toxicol Chem 21:1316-1322, 2002) to avoid weaknesses of this integrative tool. In the present paper, a novel index named "Integrated Biological Responses version 2" based on the reference deviation concept is presented.

A novel Kv1.1 potassium channel blocking toxin from the venom of Palamneus gravimanus (Indian black scorpion)
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: More,S. S.; Mirajkar,K. K.; Gadag,J. R.; Menon,K. S.; Mathew,M. K.
A peptide toxin was isolated from the venom of Palamneus gravimanus, the Indian black scorpion, to block human Kv1.1 channels expressed in Xenopus laevis oocytes. A 4.5 kD peptide (toxin), as confirmed by SDS-PAGE, was purified to homogeneity by ion exchange chromatography using CM-Sephadex C-25 followed by Sephadex G-50 gel filtration. Palamneus gravimanus toxin (PGT) selectively blocks the human cloned voltage-gated potassium channel hKv1.1 in a two-electrode voltage-clamp (TEVC) technique. The results obtained indicate that the toxin blocks the hKv1.1 channel at a nanomolar concentration range (Ki value of 10 nM) of the peptide to the external side of the cell.

Autores: Simon-colin, Christelle; Raguenes, Gerard; Crassous, Philippe; Moppert, X; Guezennec, Jean.
Pseudomonasguezennei biovar. tikehau was isolated from a microbial mat on the atoll of Tikehau in French Polynesia, and is able to synthesize medium chain length poly-beta-hydroxyalkanaote copolymers when grown on coprah oil. A two-step cultivation process was used and the biosynthesis of PHAs was followed along 52 h by regular culture sampling. The polyester was purified from freeze-dried cells and analysed by nuclear magnetic resonance (NMR), Fourier transform infra red (FTIR), and gas chromatography mass spectrometries. The copolyester produced by P. guezennei biovar. tikehau from coprah oil mainly consisted of saturated monomers, i.e. 3-hydroxyoctanoate (3HO) and 3-hydroxydecanoate (3HD), and the monomeric composition of the polyester did not change...

A novel method for diagnosing seasonal to inter-annual surface ocean carbon dynamics from bottle data using neural networks
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sasse, T. P.; Mcneil, B. I.; Abramowitz, Ag.
The ocean's role in modulating the observed 1–7 Pg C yr−1 inter-annual variability in atmospheric CO2 growth rate is an important, but poorly constrained process due to current spatio-temporal limitations in ocean carbon measurements. Here, we investigate and develop a non-linear empirical approach to predict inorganic CO2 concentrations (total carbon dioxide (CT) and total alkalinity (AT)) in the global ocean mixed layer from hydrographic properties (temperature, salinity, dissolved oxygen and nutrients). The benefit of this approach is that once the empirical relationship is established, it can be applied to hydrographic datasets that have better spatio-temporal coverage, and therefore provide an additional constraint to diagnose ocean carbon dynamics...

Provedor de dados: International Journal of Morphology
Autores: Yang,Shengbo; Hu,Shuangjiang; Tian,Xufeng; Hu,Shuaiyu.
The nerve entry points (NEPs) cannot be accurately localized for the treatment of muscle spasticity in neurolysis. The aim of this study was to develop a new method of accurately localizing nerve entry points in relation to bony landmarks. NEPs in human cadavers were coated with barium sulfate. Method 1 consisted of horizontal and longitudinal reference lines being designated based on bony landmarks, followed by radiography and measurements using picture archiving and communication system software. Method 2 involved sewing the barium sulfate-soaked suture thread into the skin to designate the horizontal and longitudinal reference lines, followed by computed tomography (CT) scanning to determine the skin surface location and puncture depth for the NEPs....

A novel missense mutation p.L76P in the GJB2 gene causing nonsyndromic recessive deafness in a Brazilian family
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Batissoco,A.C.; Auricchio,M.T.B.M.; Kimura,L.; Tabith-Junior,A.; Mingroni-Netto,R.C.
Mutations in the GJB2 gene, encoding connexin 26 (Cx26), are a major cause of nonsyndromic recessive hearing loss in many countries. We report here on a novel point mutation in GJB2, p.L76P (c.227C&gt;T), in compound heterozygosity with a c.35delG mutation, in two Brazilian sibs, one presenting mild and the other profound nonsyndromic neurosensorial hearing impairment. Their father, who carried a wild-type allele and a p.L76P mutation, had normal hearing. The mutation leads to the substitution of leucine (L) by proline (P) at residue 76, an evolutionarily conserved position in Cx26 as well as in other connexins. This mutation is predicted to affect the first extracellular domain (EC1) or the second transmembrane domain (TM2). EC1 is important for...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Hu,Jun; Xie,Xin; Li,Yuan; Wang,Shuang; Feng,Qing; Wang,Xin; Liang,Daoyan.
Prompt and accurate detection of rejection prior to pathological changes after organ transplantation is vital for monitoring rejections. Although biopsy remains the current gold standard for rejection diagnosis, it is an invasive method and cannot be repeated daily. Thus, noninvasive monitoring methods are needed. In this study, by introducing an IL-2 neutralizing monoclonal antibody (IL-2 N-mAb) and immunosuppressants into the culture with the presence of specific stimulators and activated lymphocytes, an activated lymphocyte-specific assay (ALSA) system was established to detect the specific activated lymphocytes. This assay demonstrated that the suppression in the ALSA test was closely related to the existence of specific activated lymphocytes. The ALSA...

Provedor de dados: Genetics and Molecular Biology
Autores: Shotelersuk,Vorasuk; Jaruratanasirikul,Somchit; Sinthuwiwat,Thivaratana; Janjindamai,Waricha.
Campomelic dysplasia (CD) is an autosomal dominant skeletal malformation syndrome with features including bowed lower limbs with pretibial skin dimpling, hypoplastic scapulae and pelvic bones, and 11 pairs of ribs. Mutations in the SOX9 gene have been identified to cause CD. The gene encodes a transcription factor containing a dimerization, a high mobility group, and a C-terminal transactivation (TA) domain. Up to now, 35 SOX9 mutations have been published. In the present study, we describe a Thai girl with clinically and radiologically typical CD. Direct sequencing analysis of the PCR products for the entire coding region of SOX9 revealed that she was heterozygous for a novel 448G &gt; T in exon 2 of SOX9. The DNA change was expected to result in E150X...

A novel polymorphism in the coding region of the vasopressin type 2 receptor gene
Provedor de dados: Brazilian Journal of Medical and Biological Research
Nephrogenic diabetes insipidus (NDI) is a rare disease characterized by renal inability to respond properly to arginine vasopressin due to mutations in the vasopressin type 2 receptor (V2(R)) gene in affected kindreds. In most kindreds thus far reported, the mode of inheritance follows an X chromosome-linked recessive pattern although autosomal-dominant and autosomal-recessive modes of inheritance have also been described. Studies demonstrating mutations in the V2(R) gene in affected kindreds that modify the receptor structure, resulting in a dys- or nonfunctional receptor have been described, but phenotypically indistinguishable NDI patients with a structurally normal V2(R) gene have also been reported. In the present study, we analyzed exon 3 of the...

Autores: Ming-liang,C; Cong,W; Xuan,D; Lu,L; Tang-jie,Z.
ABSTRACT The VLDLR gene plays important roles in the growth and adiposity in humans and mice. The purpose of this study was to investigate the relationship between VLDLR gene genetic polymorphisms and growth and abdominal fat traits of the Gaoyou domestic duck. A total of 267 Gaoyou ducks were employed for testing. A 18bp deletion was identified in VLDLR signal peptide coding region. The results of c2 test suggested that the genotype frequencies of VLDLR signal peptide coding region were not in Hardy-Weinberg equilibrium. Least squares analysis showed that body weight (BW) of -18bp/-18bp genotype ducks was significantly higher than those of other genotypes from six (BW6) (p&lt;0.05) to ten weeks of age (BW10) (p&lt;0.01).

ABSTRACT With the aim of introducing permanent prostheses with main properties equivalent to cortical human bone, Ti-diamond composites were processed through powder metallurgy. Grade 1 titanium and mixtures of Ti powder with 2%, 5% and 10 wt% diamond were compacted at 100MPa, and then sintered at 1250°C/2hr/10-6mbar. Sintered samples were studied in the point of view of their microstructures, structures, yield strength and elastic modulus. The results showed that the best addition of diamonds was 2 wt%, which led to a uniform porosity, yield strength of 370MPa and elastic modulus of 13.9 GPa. Samples of Ti and Ti-2% diamond were subjected to in vitro cytotoxicity test, using cultures of VERO cells, and it resulted in a biocompatible and nontoxic composite...

Provedor de dados: Nature Precedings
Autores: Ma&amp;#x142;gorzata Dudkiewicz; Anna Lenart; Krzysztof Paw&amp;#x142;owski.
Protein kinases are essential effectors of cellular signaling. Surprisingly, using bioinformatics tools, we predicted protein kinase structure and function for proteins of unknown function (FAM69 family) coded by five related human genes and their Metazoan homologues. Analysis of three-dimensional structure models and conservation of the classic catalytic motifs of protein kinases in four of human FAM69 proteins suggests they might have retained catalytic phosphotransferase activity. The FAM69 genes, FAM69A, FAM69B, FAM69C, C3ORF58 and CXORF36, are by large uncharacterized molecularly, yet linked to several neurological disorders in genetics studies. An EF-hand Ca2+-binding domain in FAM69A and FAM69B proteins, inserted within the structure of the kinase...

Autores: Liu,Zhi-Peng; Liu,Gong-She; Yang,Qing-Chuan.
The level of variation of simple sequence repeat (SSR) markers in cultivated alfalfa from American, Australian and Chinese sources was evaluated using a novel autotetraploid statistical method to calculate the effective number of alleles, the allele frequencies and heterozygosity. We used 19 SSR primers to screen seven polymorphic SSR loci in 320 plants from eight populations. The genetic distance and phylogenetic analysis (DISPAN) program was used to calculate the inter- and intra-population genetic relationships using the conventional binary absence/presence (0/1) method and our novel autotetraploid method. The autotetraploid method resulted in significantly higher heterozygosity (p &lt; 0.01), average effective number (p &lt; 0.01) and lower standard...

Synthesis of storage starch and protein accumulation is the main action of endosperm organogenesis in term of the economic importance of rice. This event is strongly disturbed by abiotic stresses such as high temperature; thus, the upcoming global warming will cause a crisis with a great impact on food production^1,2^. The enzymes for the protein storage and starch synthesis pathway should work in concert to carry out the organogenesis of rice endosperm^3-5^, but the regulatory mechanism is largely unknown. Here we show that a novel regulatory factor, named OsCEO1, acts as the conductor of endosperm organogenesis during the rice grain filling stage. The physiological properties of _floury-endosperm-2_ (_flo2_) mutants showed many similarities to symptoms...

A novel tracer technique to quantify the atmospheric flux of trace elements to remote ocean regions
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kadko, David; Landing, William M.; Shelley, Rachel.
Atmospheric input into the global ocean constitutes an important budgetary component of numerous chemical species and plays a key role in controlling biogeochemical processes in the ocean. Assessment of this input is difficult, however, because measurements of deposition rates to the ocean, particularly in remote areas, are rare and susceptible to problems of temporal and spatial variability. While the collection and analysis of aerosol samples is somewhat routine, the chemical concentration data collected from ship board or land-based aerosol samplers in and of themselves cannot yield the deposition flux of trace elements; a method is required to transform concentration measurements into flux. The ability to derive the atmospheric flux of Be-7 from its...

A numerical model for free infragravity waves: Definition and validation at regional and global scales
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ardhuin, Fabrice; Rawat, Arshad; Aucan, Jerome.
The spectral wave model WAVEWATCH III is extended from the windsea and swell band to lower frequencies, in order to represent free waves in the infragravity (IG) wave band. This extension is based on an empirical source of IG energy, which is defined along shorelines from the significant wave height and a mean period. The empirical proportionality factor is found to reproduce accurately the variations of free IG wave energy in coastal areas, where it was calibrated, and also has a good skill at global scales. In the open ocean, the model is particularly verified for frequencies in the range 5 to 14 mHz for which ocean bottom records are sensitive to the IG signal. The model captures between 30% and 80% of the variance in IG wave heights, depending on...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ndoye, S; Capet, Xavier; Estrade, Philippe; Machu, Eric; Kounta, L; Sow, B; Diakhate, M; Gayet, At.
The regional ocean circulation along the Southern Senegal shelf is studied using a numerical model for varying forcing fields during the upwelling season (November-May). The main objective is to study the shelf circulation of the marine environment in the Southern Senegal Upwelling Shelf (SSUS), the Lagrangian pathways by which waters are transported to the surface in the upwelling tongue and the fate of these waters. Model results are compared with hydrographic measurements during UPSEN2-ECOAO survey and satellite images datasets. The upwelling source waters and also the warm nearshore waters are analyzed, from a Lagrangian point of view, by computing the paths of particles that are passively advected by the regional ocean model velocity field (ROMS). It...

A numerical study of baroclinic instability at large supercriticality
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Klein, Patrice; Pedlosky, J.
A series of numerical integrations of the two-layer quasi-geostrophic model were carried out to investigate the nonlinear dynamics of baroclinically unstable waves at supercriticalities of O(1). The results extend and are contrasted with the results of weakly nonlinear theory valid only for small supercriticality. Particular attention is paid to that sector of parameter space in which the transition from regular to aperiodic behavior is observed for weakly nonlinear waves. It is found that aperiodic, chaotic behavior extends to parameter domains of higher dissipation as a consequence of finite amplitude effects as the supercriticality increases. Sensitive dependence on parameters remains a hallmark of the system as intervals of chaotic, periodic and steady...

A numerical study of the generation and propagation of internal solitary waves in the Luzon Strait
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cai, Sq; Long, Xm; Gan, Zj.
A new composite model, which consists of a generation model of the internal tides and a regularized long wave propagation model, is presented to study the generation and evolution of internal solitary waves in the sill strait. Internal bores in the sill strait are first simulated by the generation model. and then the internal tidal field outside of the sill region is given as input for the propagation model. Numerical experiments are carried out to Study the imposing tide, depth profile. channel width and shoaling effect, etc., on the generation and evolution of internal solitary waves. It is shown that only when the amplitude of internal tide at the forcing boundary of the propagation model is large enough that a train of internal solitary waves would be...

A numerical study of the nonlinear-interaction of hurricane-camille with the gulf-of-mexico loop current
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ly, Ln; Kantha, Lh.
A three-dimensional, primitive equation, ocean general circulation model is used to study the response of the Gulf of Mexico to Hurricane Camille (1969). The free-surface dynamics and the mixed-layer features are included in the model. The numerical model incorporates the realistic coastline and bottom topography. The sigma coordinate model has eighteen levels in the vertical and 0.2-degrees x 0.2-degrees horizontal resolution for the entire gulf. The study focuses on nonlinear interaction between hurricane induced currents and the Loop Current. The numerical simulations show that there is a strong nonlinear interaction between the hurricane and the Loop Current in the southern and central parts of the eastern gulf. The surface currents due to nonlinear...

A numerical study of turbulent processes in the marine upper layers
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Klein, Patrice; Coantic, Michel.
A second-order turbulence closure model, similar to Mellor and Yamada's (1974) level-3 model, is implemented. This is used to investigate the role of the different turbulent processes and the resulting dynamical and thermal structures, for oceanic upper layers subjected to a variety of unsteady atmospheric forcings. From the distributions obtained for current and temperature, turbulence levels, the production, transfer and dissipation terms in the turbulent kinetic energy and temperature variance budgets, the physics of the oceanic mixed layer and thermocline can be discussed and comparisons made with the models of Mellor and Durbin (1975), Warn-Varnas and Piacsek (1979) and Kundu (1980) and some experimental data. Most often, shear production and viscous...

A nutrition mathematical model to account for dietary supply and requirements of energy and nutrients for domesticated small ruminants: the development and evaluation of the Small Ruminant Nutrition System
Provedor de dados: Revista Brasileira de Zootecnia
Autores: Tedeschi,Luis Orlindo; Cannas,Antonello; Fox,Danny Gene.
A mechanistic model that predicts nutrient requirements and biological values of feeds for sheep (Cornell Net Carbohydrate and Protein System; CNCPS-S) was expanded to include goats and the name was changed to the Small Ruminant Nutrition System (SRNS). The SRNS uses animal and environmental factors to predict metabolizable energy (ME) and protein, and Ca and P requirements. Requirements for goats in the SRNS are predicted based on the equations developed for CNCPS-S, modified to account for specific requirements of goats, including maintenance, lactation, and pregnancy requirements, and body reserves. Feed biological values are predicted based on carbohydrate and protein fractions and their ruminal fermentation rates, forage, concentrate and liquid...

A one-month study of the zooplankton community at a fixed station in the Ligurian Sea: the potential impact of the species composition on the mineralization of organic matter
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mousseau, L.; Lefevre, D.; Narcy, F.; Nival, P.; Andersen, V.
The cruise project was designed to study temporal variations of the ecosystem during the summer-autumn transition and focused on the part played by zooplankton as top-down controllers, and the relative importance of top-down versus bottom-up controls. Zooplankton should play a key role both in the vertical transfer of particulate organic matter and in the mineralisation of organic matter. Although the importance of species diversity is well recognized, the impact of diversity on carbon fluxes is rarely considered. Trophic roles of zooplankton range from strict herbivory to strict carnivory, with all possible combinations (i.e. omnivory) between these two extremes. Feeding strategies are also very diverse, for example, active predators, passive filter...

A Palynological investigation of the Lower peat in the Province of Friesland, the Netherlands
Provedor de dados: Naturalis Digital Academic Repository
Autores: Donselaar, J. van; Jonker, F.P.
Up till now the lower deposits of peat (in Dutch: veen-op-groterediepte = peat at greater depth) have been investigated in the Netherlands mainly in the Western part of the country, viz. in the provinces of Noord-Holland, Zuid-Holland and Zeeland. The analyses have shown that the development of this, now comparatively well known peat layer must have begun either in the second half of the boreal period or else in the beginning of the atlantic one, and that it must have come to an end in the first half of the latter. Among the earlier investigators the botanist Mrs VERNEER-LOUMAN and some geologists had arrived at the conclusion that the sudden transgression of the North sea which made an end to the formation of peat, took place in the boreal period, and hat...

Pollen diagrams have been prepared of eight sections of Quaternary sediments from different localities on the coastal plain of British Guiana, and partly dated with the C 14 method. A Riss-Würm interglacial transgression, a Würm-glacial regression and a Holocene transgression have been established. The Würm-glacial vegetation on the place of the present coastal plain area was a poor grass-savanna type. The Holocene transgression at about 9500 B.P. is represented at 23 m. below present sea level and the maximum attained around 6500 B.P. when the relative sealevel was at least 2½ m. above that at present.

Globally, vibrios represent an important and well-established group of bacterial foodborne pathogens. The European Commission (EC) mandated the Comite de European Normalisation (CEN) to undertake work to provide validation data for 15 methods in microbiology to support EC legislation. As part of this mandated work programme, merging of ISO/TS 21872–1:2007, which specifies a horizontal method for the detection of V. parahaemolyticus and V. cholerae, and ISO/TS 21872–2:2007, a similar horizontal method for the detection of potentially pathogenic vibrios other than V. cholerae and V. parahaemolyticus) was proposed. Both parts of ISO/TS 21872 utilized classical culture-based isolation techniques coupled with biochemical confirmation steps. The work also...

This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates the effects of animal welfare changes on the pig production systems (pig meat) and further on trade flows (trade in pig meat) and environment (water and air pollution). We consider two animal welfare simulation scenarios, namely the status quo – no animal welfare change as regards pig neonatal mortality (baseline scenario) and the case of improving pig neonatal survival (alternative scenario) and compare the impacts on trade and environment between the two...

Identification of relevant social impact indicators for a Social Life Cycle Assessment (SLCA) is still difficult and poorly documented (Jorgensen, et al, 2009). In aquaculture systems, the studies based on social aspects are essentially focused on manpower or on conflicts with other activities . In the PISCEnLit project**, we aim to broaden the vision of social impacts of fish farming systems using a new approach of SLCA. We studied fish farming pond systems in France (Lorraine and Brenne) and Indonesia (Tangkit Baru and Kumpeh Ulu in Sumatra island). In this study, we focused on the choice of the impact categories using the participation of stakeholders (James et al., 2002) by the identification and selection of the relevant social impacts to be assessed....

A participatory research methodology was used to compare the performance of UK wheat varieties under organic conditions. Plots of three breadmaking winter wheat varieties (Hereward, Solstice and Xi19) and a mixture (1:1:1) of the varieties were grown at 19 UK farms in two seasons (2003/04 and 2004/05). Meas-urements were taken of growth habit, yield and grain quality. Grain yields in both seasons showed significant site by variety interactions, although the variation among sites was greater than among varieties in both instances. Wheat grown at Western sites was significantly shorter and higher-yielding than that grown at Eastern sites in 2003/04 but significantly taller in 2004/05. As with grain yield, greater variation among site than variety was found...

Farmer participation was essential in developing a uniquely useful set of wheat variety trials data on a wide range of organic farms over two years. Although the trials were successful, it became clear that some of the participating farmers felt there were some limitations in the process. These included a lack of ownership in the project and a concern for more researcher help. It was clear that a greater time in-vestment was needed at the start of the project to help with farmer understanding and ownership. De-spite the negative comments, farmers appreciated their involvement, particularly in contrasting their own views and information with that from the wider scene.  Farmer participation is essential for systems-level research and this project helped to...

A 10-year-old speechless, mentally deficient male, with low arylsulfatase A (ARSA) activity, and presumably, methachromatic leukodystrophy, underwent genetic evaluation. As the clinical picture was not compatible with this diagnosisan ARSA gene and chromosome analysis were performed, showing the presence of a pseudodeficiency ARSA allele and a de novo apparently balanced t(16;22)(p11.2;q13) translocation. A deletion on the long arm of chromosome 22 encompassing the ARSA gene, as shown by FISH and array-CGH, indicated a 22q13 deletion syndrome. This case illustrates the importance of detailed cytogenetic investigation in patients presenting low arylsulfatase A activity and atypical/unspecific clinical features.

A PBL MODEL WITH ORGANIZED LARGE EDDIES FOR MESOSCALE-SYNOPTIC-GLOBAL WINDS
Provedor de dados: Gayana
Autores: Brown,Robert A.
The University of Washington PBL model is a nonlinear similarity model (with organized large eddies in an equilibrium mean flow) suitable for km-scale to General Circulation Model or Climate numerical models. The theory and verification for this solution are now well established. Researchers who work with winds in the boundary layer with scales from point to 20-km regimes must be aware of this horizontal inhomogenuity in the PBL flow to avoid significant errors. Since the OLE contribute advectively to the mean flow there can be 10-20% (or more) increase in surface winds and fluxes over K-theory models. The model is described and several applications have been made

Babesia ovata is a tick-transmitted hemoprotozoan parasite that infects cattle. In our study, bovine blood samples (n=2,034) were collected from 10 different countries (Brazil, China, Ghana, Japan, Mongolia, the Philippines, South Africa, Sri Lanka, Thailand and Vietnam) and DNA extracted. The DNA samples were screened using an established and specific polymerase chain reaction (PCR) assay targeting the Apical membrane antigen 1 (AMA-1) gene. Parasite DNA was detected among samples collected from Japan, Mongolia and Thailand. Sequence analyses confirmed that the PCR assay detected only B. ovata AMA-1, and that amplicons from different geographical locations were conserved. Our findings highlight the importance of designing adequate strategies to control B....

A Performance Analysis of the Supply of Public Goods in Rural Communities Based on the System Implementation Costs - Taking Chongren county Bailu village, Taihe County Yongchang village as examples
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zheng,   Shuang-sheng.
Based on the survey of Chongren county Bailu village, Taihe county Yongchang village and by focusing on the system implementation costs, the public goods is divided into tangible products and intangible products these 2 parts to carry out a perfomance analysis of the supply of public goods in rural communities. It points out that in both the well-acquainted and rare-acquainted communities in rural areas there are some long-existing informal systems, such as religions. Because of their born nature, the system implementation costs are relatively lower. However, the implementation costs of the embedded foreign systems are relatively higher because of their weaker lasting features and the rare social basis. Therefore, proposing putting the efficient supply of...

A PERFORMANCE EVALUATION OF FIVE SWEETPOTATO SHIPPING CONTAINERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Estes,   Edmund A.; Wilson,   L. George; Bandele,   Owusu.
Using a six x six latin square experimental design, five box types in two different markets were evaluated over a six-week period in 1986 to determine if sweetpotato arrival damage could be reduced through use of alternative shipping containers. Findings indicated that skinning, cut and break damage, and bruising could be reduced through use of either a 40-pound container or the 45-pound MUM box rather than using the current 50-pound box. Economic considerations, receiver preferences, and the actions of shippers resulted in the selection of a 40-pound shipping carton as the new standard for the North Carolina sweetpotato industry.

Provedor de dados: Entomología y Vectores
Autores: Ahmed,A. B.
The present article considers some aspects of a peridomestic population of the tsetse fly Glossina palpalis palpalis Robineau-Desvoidy, 1830 in Kontagora, Nigeria. This situation characterizes an abnormal behaviour of the vector, and it is of significant epidemiological importance. Data on the ecology of this species were collected in 1995 and 1999. The results indicated that the species exists during both dry and wet seasons; approximately 30.0% of the catches were gorged with blood giving a MHS of 2.4, indicating a well-nourished population. Dissection of inseminated pars indicated pregnancy rates of approximately 30.0% and 70.0% in the dry and wet seasons and the presence of all 4 stages of pregnancy, suggesting that breeding occurs at both seasons....

A periodic pattern of SNPs in the human genome
Provedor de dados: Nature Precedings
Autores: Bo Eskerod Madsen; Palle Villesen; Carsten Wiuf.
By surveying all validated SNPs in the human genome we have found that SNPs positioned 1, 2, 4, 6 or 8 bp apart are more frequent than SNPs 3, 5, 7 or 9 bp apart. This holds even when we correct for nucleotide frequencies and site dependencies in nucleotide usage in the genome. The observed pattern is not restricted to any of the genomic regions that might give sequencing or alignment errors; i.e. transposable elements (SINE, LINE and LTR), tandem repeats and large duplicated regions. However we can define periodic DNA, which virtually capture the entire pattern. Periodic DNA is defined as small DNA sequences (16.9 bp average length) with a high degree of periodicity in nucleotide usage. Periodic DNA is widely distributed in the genome, underrepresented in...

Provedor de dados: Organic Eprints
Autores: Zhang, Fusuo; Qiao, Yuhui; Wang, Fanghao; Zhang, Weifeng.
With the rapid development of international production and trade in organic food, organic agriculture is also boosting in China. The milestone of Chinese organic agri-culture was set in 1990 with the first export of a certified organic product (tea) from Lin’an county of Zhejiang Province, China, which marked the launch of organic pro-duction in China. By the end of 2005, there had been about 4.384 million ha organic land, including 1.694 million ha organic, 0.61 million ha conversion as well as 2.08 million ha collection area, about half of which is certified area. About 4.93 million tons organic products and nearly 1600 projects had been certified with 300~400 varieties. According to the above data, now China ranks the 3rd largest country of organic...

Autores: SANTOS,Geraldo Mendes dos; OLIVEIRA Jr,Arnaldo Braga de.
A hidrelétrica de Balbina localiza-se no rio Uatumã, a 170 km de Manaus, pela BR/174. O enchimento do reservatório iniciou-se em outubro/87 e a usina começou a funcionar em fevereiro de 1989, com apenas uma das suas cinco turbinas. Apesar da redução da diversidade da ictiofauna e dos danos ambientais e sociais decorrentes do represamento, algumas espécies de peixes proliferaram no reservatório, resultando no incremento da atividade pesqueira, praticada basicamente sobre os estoques de tucunaré (Cichla spp). A explotação desta espécie, iniciada logo após a formação do reservatório, vem sendo feita até os dias atuais, com uma produção média em torno de 500 toneladas/ano e da qual participam 100 a 160 pescadores profissionais, além de dezenas de amadores.

Autores: Kiffer,Carlos R.V.; Kuti,Joseph L.; Mendes,Caio M.F.; Oplustil,Carmen P.; Amarante,Jorge B.; Biancalana,Maria L.; Xavier,Nelson; Nicolau,David P.
Pharmacodynamic analyses were proposed to determine optimal empirical antibiotic therapy against Gram-negative bacteria isolated in a Brazilian ICU. Due to high resistance rates, standard regimens of cefepime, ciprofloxacin, meropenem, and piperacillin/tazobactam were not able to attain significant bactericidal CFR. Prolonged infusion of meropenem achieved 88% CFR, making it a possible empirical regimen in this ICU until susceptibilities become available. Still, even through administration of high dose prolonged infusions, 12.0% of simulated subjects did not achieve bactericidal exposure, suggesting that combination therapy would frequently be required in this setting. In conclusion, we recommend that in the presence of identified resistance problems among...

During the 1973 cruise of the BIOGAS deep-sea program, a series of 83 frames showing a high population density of the isocrinid stalked crinoid Diplocrinus (Annacrinus) wyvillethomsoni was obtained from a depth of 1246 m on the bathyal slope of the Bay of Biscay. The spatial distribution of D. wyvillethomsoni appears to be highly aggregated. Mean density is 0.61 m-² with confidence limits determined as 0.53 and 0.69 m-², ranging up to 8 or 10 specimens m-² on a sea floor with pebbles and rocks. D. wyvillethomsoni forms a parabolic filtration fan with its arms strongly recurved into the current.  The distal group of cirri grips pebbles or the sharp upper edges of rocks. This active mode of anchorage contrasts with the passive mode in other genera of...

ABSTRACT Interpolyelectrolyte complexes, which constitute a type of polymeric material obtained through the self-assembly of oppositely charged polymers, exhibit interesting properties for use in the design of smart matrices for drug delivery. In the present study, a stoichiometric interpolyelectrolyte complex (SIPEC) composed of Eudragit E® and Eudragit® L100 was obtained at pH 6.0 and characterized and evaluated as a hydrophilic matrix for dexibuprofen. The formation of a SIPEC was monitored by ζ-potential measurements and characterized using infrared spectroscopy, thermal analysis, and scanning electron microscopy. The results indicated that a SIPEC obtained under these conditions can be used as a matrix for controlling the release of dexibuprofen and...

A phylogenetic study of Boletus section Boletus in Europe
Provedor de dados: Naturalis Digital Academic Repository
Autores: Beugelsdijk, D.C.M.; Linde, S. van der; Zuccarello, G.C.; Bakker, H.C. den.
A phylogenetic study of the species in Boletus sect. Boletus was undertaken using the molecular markers ITS1-5.8S-ITS2 and Gap dh. Four well-supported lineages, one comprising Boletus edulis s.l., the others referring to B. aereus, B. reticulatus and B. pinophilus have been distinguished. The ML and MP trees of ITS showed remarkably low resolution within the B. edulis clade, and confirmed earlier published results, despite the use of samples from a wider geographical area and different hosts. The results of Gap dh demonstrate clearly that this low resolution must be ascribed to a low genetic variability with the B. edulis clade, and make clear that morphological and ecological characters have been overestimated within this species complex.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gonzalez-araya, Ricardo; Queau, Isabelle; Quere, Claudie; Moal, Jeanne; Robert, Rene.
To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T-ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica&lt;C. gracilis&lt;S. marinoï. When oysters were fed either...

A Physiological Role for Amyloid Beta Protein: Enhancement of Learning and Memory
Provedor de dados: Nature Precedings
Autores: John Morley; Susan Farr; William Banks; Steven N. Johnson; Kelvin A. Yamada; Lin Xu.
Amyloid beta protein (A[beta]) is well recognized as having a significant role in the pathogenesis of Alzheimer&amp;#x27;s disease (AD). The reason for the presence of A[beta] and its physiological role in non-disease states is not clear. In these studies, low doses of A[beta] enhanced memory retention in two memory tasks and enhanced acetylcholine production in the hippocampus _in vivo_. We then tested whether endogenous A[beta] has a role in learning and memory in young, cognitively intact mice by blocking endogenous A[beta] in healthy 2-month-old CD-1 mice. Blocking A[beta] with antibody to A[beta] or DFFVG (which blocks A[beta] binding) or decreasing A[beta] expression with an antisense directed at the A[beta] precursor APP all resulted in impaired...

Autores: Nicholas, Dr. Phillipa; Lampkin, Dr. Nicolas; Leifert, Prof. Carlo; Butler, Dr. Gillian; Klocke, Peter; Wagenaar, J.P.T.M.
A pilot socio-economic impact assessment was carried out on three dairy projects within QLIF to identify the business, consumer and policy issues likely to influence the adoption of the innovations resulting from QLIF.  A socio-economic analysis is pre-sented related to the key outcomes from the three projects which include: manage-ment systems to reduce mastitis and antibiotic use in organic dairy farms and how milk quality can be enhanced through high forage organic feeding systems.  Due to a lack financial data costs had to be assumed based on other studies. The socio-economic analysis identified a significant number of potential economic and social implications of implementing strategies developed in the QLIF project that aim at increasing animal...

Diabetic nephropathy (DN) is one of the major complications of type 2 diabetes and is associated with coronary disease. Nephrin, a protein mainly expressed in glomeruli, is decreased in DN and other kidney diseases. Since insulin levels are misregulated in type 2 diabetes, a possible connection between DN and its decreased nephrin expression could be the presence of regulatory elements responsive to insulin in the nephrin gene (NPHS1) promoter region. In this work, using bioinformatic tools, we identified a purine-rich GAGA element in the nephrin gene promoter and conducted a genomic study in search of the presence of polymorphisms in this element and its possible association with DN in type 2 diabetic patients. We amplified and sequenced a 514 bp promoter...

A plate method for rapid screening of Ketogulonicigenium vulgare mutants for enhanced 2-keto-l-gulonic acid production
Provedor de dados: Brazilian Journal of Microbiology
Autores: Yang,Weichao; Han,Litao; Mandlaa,Mandlaa; Zhang,Haihong; Zhang,Zhongze; Xu,Hui.
Abstract A new plate method was developed for rapid screening of Ketogulonicigenium vulgare mutants overproducing 2-keto-l-gulonic acid (2-KLG). The screening methodology took the advantage of the acidity caused by 2-KLG, which changes the color of bromothymol blue (pH indicator) from blue to yellow. Using the proposed method, a mutant, K. vulgare 65, was selected from 20,000 colonies produced by a strain subjected to spaceflight mutagenesis. When co-cultured with Bacillus megaterium 2980 in 20-L fermenters, K. vulgare 65 showed a high conversion rate (94.45%) of l-sorbose to 2-KLG. In contrast to the traditional screening method, this one significantly improved the frequency of obtaining positive mutants. The proposed plate screening method is...

A Pliocene-Pleistocene stack of 57 globally distributed benthic delta O-18 records
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lisiecki, Le; Raymo, Me.
We present a 5.3- Myr stack ( the " LR04'' stack) of benthic delta(18)O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic delta(18)O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the early Pliocene. We also present a new LR04 age model for the Pliocene- Pleistocene derived from tuning the delta(18)O stack to a simple ice model based on 21 June insolation at 65degreesN. Stacked sedimentation rates provide additional age model constraints to prevent overtuning. Despite a conservative tuning strategy, the LR04 benthic stack exhibits significant coherency with insolation in the...

A Pliocene–Quaternary analogue for ancient epeiric carbonate settings: The Malita intrashelf basin (Bonaparte Basin, northwest Australia)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Courgeon, Simon; Bourget, Julien; Jorry, Stephan.
During the Plio-Quaternary, the Bonaparte Basin is characterized by a very wide (&gt; 600 km, &gt; 370 mi) carbonate platform and 200 km-wide (125 mi-wide) intra-shelf basin (the Malita ISB). Using 3D and 2D seismic data combined with exploration well data, this study characterizes the stratigraphic evolution of the Malita ISB during the last 3.5 million years. Two third-order transgressive sequences can be distinguished. A late Pliocene transgression occurred over an irregular topography resulting from the flexural reactivation of the Malita graben. In the centre of the intra-shelf basin, carbonate aggradation resulted in the formation of isolated carbonate platforms separated by deeper water seaways and inter-platform areas. Wider and more numerous...

A Policy Analysis Perspective on Ecological Restoration
Provedor de dados: Ecology and Society
Autores: Baker, Susan; Cardiff School of Social Sciences/Sustainable Places Institute, Cardiff University; BakerSCM@cardiff.ac.uk.
Using a simple stages model of the policy process, we explore the politics of ecological restoration using an array of examples drawn across sector, different size and scale, and from different countries. A policy analysis perspective reveals how, at both the program and project levels, ecological restoration operates within a complex and dynamic interplay between technical decision making, ideologies, and interest politics. Viewed through the stages model, restoration policy involves negotiating nature across stages in the policy making process, including agenda setting, policy formulation, implementation, and evaluation. The stages model is a useful heuristic devise; however, this linear model assumes that policy makers approach the issue rationally. In...

A Policy Impact Model for Organic Farming in Switzerland
Provedor de dados: Organic Eprints
Autores: Sanders, Juern; Lampkin, Nicolas; Midmore, Peter; Stolze, Matthias.
Although organic farming has expanded significantly in Europe in the last decade, a sectoral policy model is still missing that is able to analyse the impact of policy measures on organic farming. The use of programming models in the form of a sector-consistent farm group model seems to be a promising model approach, whereas applied general equilibrium models are regarded as less promising. An example is given for a policy impact model for organic farming. The bottom-up structure of this type of model makes it possible to analyse the impact of policy measures on farm incomes and volumes of production of organic and conventional farms at farm, regional and sectoral level.

This brief is divided into four parts.  Part one provides a basic description of the agricultural production process as a dynamic flow, producing not only commodities but environmental goods and "bads"(damages).  Part two discusses the research agendas that have influenced this production process, and the conflicts between traditional commodity oriented research and the newer environmental research agenda.  Part three takes up the common ground uniting these two agendas:  a concern for the uses of land and the effects of this use on both commodity and environmental flows.  Part four offers some specific recommendations for reforms in land policy and targeting at the national level, the farm level, and the implications of these reforms for agricultural...

A policy relevant assessment of the environmental impacts of organic farming
Provedor de dados: Organic Eprints
Autores: Dabbert, S.; Stolze, M.; Häring, A.M.; Piorr, A.
Organic farming has become an important aspect of European agri-environmental policy. Since the implementation of EC Reg. 2078/92, the EU promotes organic farming based explicitly on its positive effects on the environment. The objective of this paper is to contribute to a better understanding of organic farming's effects on the environment in comparison to conventional farming and to discuss the policy relevance of these issues.  For this purpose the OECD set of environmental indicators for the agricultural sector has been adapted, taking into consideration only those indicators that are directly affected by the system of organic farming, as are the indicator categories ecosystem, natural resources, farm input and output, and health and welfare. Based on...

A pollen diagram from “Laguna de la Herrera” (Sabana de Bogota)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hammen, T. van der; Gonzalez, E.
The Laguna de La Herrera (alt. ca 2550 m) is a lake situated on the western border of the Sabana de Bogotá, near Mosquera (dept. of Cundinamarca, Colombia) (fig. 2). This part of the Sabana has a relatively dry climate (appr. 600—700 mm rainfall), as it lies in the rain-shadow of the hills that border the Sabana on its western edge, and it bears therefore a xerophytic vegetation. The western slopes of the bordering mountains, that fall steeply to warmer valleys, have a much higher rainfall and are almost continuously clouded. They bear therefore a cloud-forest, of the Quercetum type, that reaches partly the very top of these mountains. Fig. 1 shows this in an idealized section. For further details on the mentioned vegetation-types, we may refer to van der...

Porcine circovirus 2 is nowadays accepted as the essential infectious agent of postweaning multisystemic wasting syndrome which causes severe economic losses in porcine production worldwide. The diagnosis of PMWS is a difficult task and must follow three criteria: (i) the presence of compatible clinical signs, (ii) the presence of characteristic microscopic histopathological lesions, and (iii) the presence of PCV2 within these lesions in moderate or high. The presence of PCV2 in lymphoid tissues must be demonstrated by in situ hybridization or immunohistochemical methods. The in situ hybridization is a more complex and expense compared to other diagnostic tools, on the other hand, one problem concerning the immunohistochemical methods for PMWS diagnostic...

A polygenic hypothesis for sex determination in the European sea bass - Dicentrarchus labrax
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Vandeputte, Marc; Dupont Nivet, M; Chavanne, H; Chatain, Beatrice.
Polygenic sex determination, although suspected in several species, is thought to be evolutionarily unstable and has been proven in very few cases. In the European sea bass, temperature is known to influence the sex ratio. We set up a factorial mating, producing 5.893 individuals from 253 full-sib families, all reared in a single batch to avoid any between-families environmental effects. The proportion of females in the offspring was 18.3%, with a large variation between families. Interpreting sex as a threshold trait, the heritability estimate was 0.62 +/- 0.12. The observed distribution of family sex ratios was in accordance with a polygenic model or with a four-sex-factors system with environmental variance and could not be explained by any genetic...

A polyocular framework for research on multifunctional farming and rural development
Provedor de dados: Organic Eprints
Autores: Noe, Egon; Alrøe, Hugo F.; Langvad, Anne Mette S.
The paradox of multifunctionality is that, on the one hand, the specialized functionalities of agriculture only arise because of the functional differentiation of social systems and scientific disciplines and, on the other hand, multifunctionality can only enter as a way to mediate between conflicts, interests and fragmented knowledge when different functions and observations of functions combine. The aim of this paper is to contribute to a theoretical and methodological platform for multidisciplinary research on multifunctional farming. With the notions of polyocular cognition and polyocular communication we introduce a second order, interdisciplinary communication process that can meet the challenge of creating a shared view on multifunctional farming....

A portable bio-amplifier for electric fish research: design and construction
Provedor de dados: Neotropical Ichthyology
Autores: Wells,Jonathan K.; Crampton,William G. R.
The weak electric organ discharges (EODs) of gymnotiform knife fishes can be readily amplified with a wideband amplifier connected to submerged electrodes. The output from such an amplifier can then be monitored with audio speakers or digitized for subsequent analysis. Commercially available devices are expensive and usually require mains electrical power. Here we provide design notes and instructions for the construction and calibration of a cheap, portable, battery-powered, AC-coupled wideband bio-amplifier. This device was designed to allow electric fishes to be located in the field, and also to permit the relatively noise-free acquisition of EOD waveforms from specimens held in temporary captivity. This contribution is intended to encourage students of...

The challenge confronting those seeking to understand the institutional dimensions of global environmental change and patterns of land-use and land-cover change is to find effective methods for analyzing the dynamics of socio-ecological systems. Such systems exhibit a number of characteristics that pose problems for the most commonly used statistical techniques and may require additional and innovative analytic tools. This article explores options available to researchers working in this field and recommends a strategy for achieving scientific progress. Statistical procedures developed in other fields of study are often helpful in addressing challenges arising in research into global change. Accordingly, we start with an assessment of some of the enhanced...

A possible chelonian egg from the Brazilian late cretaceous
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: AZEVEDO,SERGIO ALEX; GALLO,VALÉRIA; FERIGOLO,JORGE.
This paper describes a possible fossil egg proceeding from the Bauru Group, Late Cretaceous of Paraná Basin, Brazil. External morphology, dimensions, texture and shell ornamentation examined under electron microscopy show close resemblance to the Recent podocnemidid chelonian eggs. Association with bony material in the outcrop suggests that it is related to a species of Podocnemis. Computerized tomography reveals a high density outer region corresponding to the shell component layers, and successive layers with decreasing density towards the nucleus. An area of high density in the central region may represent remains of an embryo.

A possible synsedimentary origin for the Cala Magnetic Iron Ores (Western Sierra Morena). A thermodynamical model
Provedor de dados: Naturalis Digital Academic Repository
Autores: Pérez, Benjamín Calvo.
The Magnetic Metallogenic Province of southwestern Spain has a large number of iron mines, in which magnetite and pyrite are the main ores. The largest of these mines, the Cala Mine, is placed in a Lower Cambrian environment, in the contact between a granitic apophysis and limestones. As a result, an important zone of skarn rocks (bearing pyroxene, amphiboles, garnet, epidote, etc.) is formed, and dealing with these rocks are the main stratiform orebodies. There is an old discussion about the origin of the mineral deposits. Some authors believe in a sedimentary genetic type, while others propose a contact-pneumatolitic process, related with the granitic stock. In this paper we try to prove that a primary sedimentary origin is possible for the magnetite....

The north-western Black Sea shelf is the widest continental shelf of the Black Sea, where the Danube delta/prodelta system includes important records on the Black Sea water level fluctuations. This study integrates newly acquired high-resolution single channel seismic reflection profiles and Calypso piston cores recovered along a transect extending from the Danube delta deep into its deep sea fan. The correlated results provide information on the Late Quaternary architecture of the Danube Black Sea shelf and on the role of global glacio-eustatic fluctuations on the building of the Danube delta/prodelta. The sedimentary sequences in the Black Sea are strongly affected by water level changes. For the whole duration of Late Glacial-Holocene period, the level...

A Potential Composite Material for Possible Applications in Earth Reinforcement
Provedor de dados: Agricultural Engineering International : The CIGR e-journal
Autores: M. Z. Hossain.
It is evident that the inadequate frictional resistance and meager cohesion of conventional reinforcements in reinforced earth structures such as geogrids, geosynthetics and wire meshes are serious shortcomings that not only impose constraints in structural designs, but also affect the stability of reinforced earth structures. In this regard, the benefits of earth reinforcing materials in improving the interaction resistances are eminent. For the reinforcement to be effective, two conditions need to be satisfied i.e. it must possess enough strength to withstand tension failure and adhesion failure. This paper highlights some experimental results on the performance behavior of thin cementitious composite elements reinforced by wire meshes under shear tests...

Autores: Wriddhiman Ghosh; Prabir Haldar; Sabyasachi Bhattacharya; Jaideb Chatterjee; Prosenjit Pyne; Masrure Alam.
The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups. It is widely believed that primordial endosymbiosis occurred in the last common ancestor of all algae^1^, which then diverged into the three primary photosynthetic eukaryotic lineages, viz. the Rhodophyta (red algae), Glaucocystophyta (cyanelle-containing algae) and Viridiplantae (green algae plus all land plants)^2^. Members of these three groups invariably have double membrane-bound plastids^3^, a property that endorses the primary endosymbiotic origin of the organelles. On the other hand, the three or four membrane-bound plastids of the evolutionary...

A potential diagnostic biomarker: Proteasome LMP2/b1i-differential expression in human uterus neoplasm
Provedor de dados: Nature Precedings

Uterine leiomyosarcoma (ULMS) develops more often in the muscle tissue layer of the uterine body than in the uterine cervix. The development of gynecologic tumors is often correlated with female hormone secretion; however, the development of uterine ULMS is not substantially correlated with hormonal conditions, and the risk factors are not yet known. Importantly, a diagnostic-biomarker which distinguishes malignant ULMS from benign tumor leiomyoma (LMA) is yet to be established. Accordingly, it is necessary to analyze risk factors associated with uterine ULMS, to establish a treatment method. Proteasome low-molecular mass polypeptide 2(LMP2)/b1i-deficient mice spontaneously develop uterine LMS, with a disease prevalence of ~40% by 14 months of age. We...

The 3-PG (Physiological Principles in Predicting Growth) radiation-use efficiency model has been widely used and tested for predicting the primary productivity of forests all over the world. This radiation-use efficiency model accounts for plant nutrition through a user-defined dimensionless fertility parameter (fN) that determines the effects a unit of radiation. Currently, this fertility parameter has to be entered by the user based on intuition or experience. The goal of this study was to propose a fertility...

Ultrasonography (US) has been applied to the ovary and the uterus of domestic animals from the late 1980s, and established in 1990s as a practical tool for animal production. US made it possible to detect pregnancy at a very early stage and, most importantly, to observe the real-time dynamics of follicular development and hence the discovery of follicular waves. This has greatly contributed to our understanding of ovarian physiology and helped us to develop several "pin-point" protocols for hormonal treatment. While US may not seem to fit preconceived ideas of a "green" technology, it does not contravene environmental priorities, and it is non-invasive ("ethical") and non-hormonal ("clean"). Using the US technology that is now commercially available at a...

A practical approach for assessing the efficiency of coated urea on controlling nitrogen availability
Provedor de dados: Bragantia
Autores: Mesquita,Geisa Lima; Zambrosi,Fernando César Bachiega; Cantarella,Heitor.
ABSTRACT We propose an approach for assessing the efficiency of coating materials on controlling nitrogen (N) availability to plants. It is based on the use of coated and soluble urea (UR) applied to corn over 3 growing cycles, as follows: coated UR with longevity of 2 (UR-2m) or 4 months (UR-4m) with application of 900 mg N∙pot−1 at the beginning of the experiment, soluble UR with a split application of 900 mg N∙pot−1 (300 mg N∙pot−1 per growing cycle, UR-3x), soluble UR with a sole application of 900 mg N∙pot−1 at the beginning of the experiment (UR-1x), and a control treatment. At the end of each growing cycle, shoots were harvested to estimate N provision by the UR by quantifying dry matter (DM) and N uptake. In the first cycle, UR-2m and UR-4m...

A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Barroco,A.C.; Sperandio,P.A.; Reis,M.; Almeida,D.R.; Neder,J.A.
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (deoxi-Hb) as measured by near-infrared spectroscopy (NIRS). We aimed to establish a simplified approach to extract deoxi-Hb-based indices of impaired muscle O2 delivery during rapidly-incrementing exercise in heart failure. We continuously probed the right vastus lateralis muscle with continuous-wave NIRS during a ramp-incremental cardiopulmonary exercise test in 10 patients (left ventricular ejection fraction &lt;35%) and 10 age-matched healthy males....

A practical approach to the understanding and teaching of RNA silencing in plants
Provedor de dados: Electronic Journal of Biotechnology
Autores: Bazzini,Ariel A; Mongelli,Vanesa C; Hopp,H. Esteban; del Vas,Mariana; Asurmendi,Sebastián.
Gene silencing, also called RNA interference (RNAi) is a specific mechanism of RNA degradation involved in gene regulation, development and defense in eukaryotic organisms. It became an important subject in the teaching programs of molecular biology, genetics and biotechnology courses in the last years. The aim of this work is to provide simple and inexpensive assays to understand and teach gene silencing using plants as model systems. The use of transient and permanent transgenic plants for expressing reporter genes, like those derived from jellyfish green fluorescent protein (gfp) encoding gene, provides a nice, colorful and conclusive image of gene silencing. Three experimental approaches to evidence RNA silencing are depicted. In the first approach...

In this study, different growth conditions of Anthracophyllum discolor Sp4 including the effect of agitation, additions of lignocellulosic support, inducer and surfactant were evaluated on the MnP production in Kirk medium using a culture system made up of the tubes containing the glass bead . The highest MnP production (1,354 U/L on day 13) was obtained when the medium was supplemented with wheat grain and 0.25 mM MnSO4 as inducer, under static conditions at 30°C. Two isoenzymes were purified (35 and 38 kDa respectively). MnP presented a maximal activity in the pH range between 4.5 and 5.5, a relatively high temperature tolerance (50ºC) and a high catalytic activity for 2,6-dimethoxyphenol and hydrogen peroxide.

A PRACTICE APPLICABLE MODEL FOR THE ASSESSMENT OF MANAGEMENT IMPACT ON ORGANIC MATTER IN ARABLE SOILS
Provedor de dados: Organic Eprints
Autores: Brock, Christopher; Leithold, Günter.
We present the HU-MOD-2 model for the assessment of management impact on organic matter levels in arable soils. The model aims at optimal applicability as a management support tool in framing practice and therefore requires only easily available input data. In validation, the tool proved to be capable of giving a rough estimate on soil organic matter changes in arable soils. Taking into account the low demand for input data, the modeling error seems tolerable for a practice applicable decision support tool.

A precariedade do transporte rodoviário brasileiro para o escoamento da produção de soja do Centro-Oeste: situação e perspectivas
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Correa,Vivian Helena Capacle; Ramos,Pedro.
O Centro-Oeste do Brasil se destaca como um pólo produtor de soja. Pela crise fiscal do Estado, a partir dos anos 80, a malha rodoviária brasileira perde investimentos públicos para sua ampliação, conservação e restauração, refletindo na competitividade internacional da oleaginosa dos cerrados. Isso porque o principal modal utilizado para o escoamento da produção do grão aos portos das regiões Sul e Sudeste é o rodoviário, com destaque para as rodovias BR 163 e 364. Por conta da inadequação desse modal às características do produto e às longas distâncias percorridas, aliada ao estado precário de conservação da malha rodoviária do País, 25% da receita de vendas da produção de soja está comprometida com os custos internos de transportes.

A precise search for drastic temperature shifts of the past 40,000 years in southeastern Europe
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Menot, Guillemette; Bard, Edouard.
Climatic models simulate abrupt oscillations that are associated, in the North Atlantic, with Dansgaard-Oeschger and Heinrich events. However, the geographic extension of temperature anomalies is largely uncontrolled due to the scarcity of quantitative records of sufficient time resolution on the European continent. Here, we propose, based on a recently developed temperature proxy (TEX86), a reconstruction of millennial-scale temperature variations in a Black Sea sediment archive for the last 40,000 years. Prior to any paleoclimatological interpretations the effects of potential bias, such as seasonality and depth of maximum export production on temperature reconstructions, are considered for the Black Sea. Based on previous work, a tentative method for...

Autores: Jin, Chunsheng; Liu, Qingsong; Cruz Larrasoana, Juan.
We report high-resolution palaeomagnetic results across the lower part of S8 in the Luochuan area, northwest of China using parallel subsets samples. A palaeomagnetic anomaly with low palaeointensity and disordered magnetic direction was identified similar to 21 ka prior to the MatuyamaBrunhes (MB) polarity reversal, and is consistent with the MB precursor observed from marine sediments and lava flows. This is the first convincing report of the MB precursor in terrestrial material (Chinese loess), which attests the global feature of the MB precursor. Constrained by the stratigraphic position of both the MB polarity reversal and the MB precursor, the loess unit L8 and palaeosol unit S8 of the Chinese loess sequence are undoubtedly tied to the marine isotope...

Autores: Mohd. Raih,Mohd. Firdaus; Sailan,Ahmad Tarmidi; Zamrod,Zulkeflie; Embi,Mohd. Noor; Mohamed,Rahmah.
Cytochrome c oxidase, the terminal enzyme of the respiratory chains of mitochondria and aerobic bacteria, catalyzes electron transfer from cytochrome c to molecular oxygen. The enzyme belongs to the haem-copper-containing oxidases superfamily. A recombinant plasmid carrying a 2.0 kb insert from a Burkholderia pseudomallei genomic library was subjected to automated DNA sequencing utilizing a primer walking strategy. Analysis of the 2002 bp insert revealed a 1536 bp open reading frame predicted to encode a putative cytochrome c oxidase. Further analysis using sequence alignments and tertiary structure analysis tools demonstrated that the hypothetical B. pseudomallei cytochrome c oxidase is similar to cytochrome c oxidases from other organisms such as Thermus...

We studied the distribution of Andinomys edax (Rodentia, Cricetidae, Sigmodontinae) in northwestern Argentina. Presence data obtained from field records, museum specimens and literature were used to model the potential distribution of this species. Andinomys edax was known in Argentina from only 41 occurrence localities, most of them restricted to Jujuy province. Here we add new localities from Catamarca, Jujuy, Salta and Tucumán provinces. We used the maximum entropy method (Maxent) and seven environmental variables to produce a potential distribution map of the species. The 7.015 cumulative threshold (corresponding to the equal test of sensitivity and specificity) was the most efficient hypothetical distribution according to the omission rate. The area...

A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil
Provedor de dados: Biota Neotropica
Autores: Souza,Natália Freitas de; Baptista,Darcílio Fernandes; Buss,Daniel Forsin.
Abstract: Biological assessments that use the reference condition approach are based on the concept of comparing a site's observed biology to sites where disturbance is minimal or absent. However, in many regions of the world, such areas are scarce or nonexistent. In this study, an alternative approach proposed by Chessman and Royal for bioassessment without reference areas based on environmental filters was tested in Brazil. This approach assumes that key environmental features act in the selection of potential colonists, from a regional pool of taxa, based on the ecological traits (tolerances) possessed by each taxon. We developed the approach by: 1) determining the regional pool, based on a large Atlantic Forest biome database; 2) selecting...

Abstract: Multimetric Indices (MMIs) have been widely applied for ecological assessment in freshwater ecosystems. Most MMIs face difficulties when scaling up from small spatial scales because larger scales usually encompass great environmental variability. Covariance of anthropogenic pressures with natural environmental gradients can be a confounding factor in assessing biologic responses to anthropogenic pressures. This study presents the development and validation of a predictive multimetric index to assess the ecological condition of Atlantic Forest wadeable streams using benthic macroinvertebrates. To do so, we sampled 158 sites for the index development. We adjusted each biological metric to natural variation through multiple regression analyses...

A preliminary account on the geology of the Selbu-Tydal area, the Trondheim region, Central Norwegian Caledonides
Provedor de dados: Naturalis Digital Academic Repository
Autores: Olesen, N.Ø.; Hansen, E.S.; Kristensen, L.H.; Thyrsted, T.
Sediments and volcanic rocks (ophiolites) all of early Palaeozoic age were metamorphosed, multiply deformed, and intruded by igneous rocks during the Caledonian orogeny. At least six deformation phases including late faults are recognized. There is no simple correlation between deformation phases and tectonic style. The second deformation phase (D2) is accompanied by Barrovian type metamorphism, ranging from biotite to sillimanite grade, and transposes earlier surfaces into a new foliation, which is itself folded on a regional scale. The transposition foliation varies from crenulation cleavage to schistosity. Basic intrusives are rimmed by contact metamorphic aureoles also of syn-D2 age. Acid intrusives are of syn- to post-D2 age. Structural and...

The currently recommended by WHO for prevention individuals exposed to rabies virus (RV) is pre-exposure prophylaxis (PEP) through the administration of three doses of rabies vaccine by intradermal (ID) or intramuscular (IM) route. The previous study showed that the persistence of protective antibodies titer in the IM schedule is more long-lived, suggesting a different clearance mechanism of antibody. It known that carbohydrate modification of antibodies could induce accelerated clearance or modulate of antibody effector functions. All endogenous IgG antibodies contain an N-linked glycan in the Fc region and about 20% contain glycans elsewhere on the molecule to maintain the two heavy chains of the Fc in an open conformation required for interactions with...

A PRELIMINARY ANALYSIS OF THE PROPOSED 1998 TAXPAYERS' RIGHTS AMENDMENTS TO THE IOWA CONSTITUTION AND FISCAL CONSEQUENCES ASSUMING IMPLEMENTATION FROM FY1984 TO PRESENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Edelman,   Mark A.
This staff paper reviews the Senate (SSB2072) and House (HSB688) versions of a proposed 1998 Amendment to the Iowa Constitution and provides a preliminary analysis of the fiscal impacts on the state general fund receipts, general fund appropriations, and local property taxes assuming each proposal was implemented in FY 1984. While the year-to-year reductions in spending are relatively small, the cumulative fiscal impact of the SSB2072 would likely have resulted in (1) a FY1997 state general fund limit that allows 32 percent less spending than actual FY1997, (2) a $710 million reduction in the growth of state aid to local government, and (3) a 29.7 percent increase in property taxes, if property taxes were used to fully replace the reduction in growth of...

A preliminary assessment of coral bleaching in Mozambique
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Schleyer, M.; Obura, D.; Motta, H.; Rodrigues, M.J.
The 1997-1998 El Niño southern oscillation caused elevated sea temperatures that resulted in global coral bleaching. Coral reefs constitute an important biological resource in terms of their complex biodiversity and are the basis for tropical fisheries and marine ecotourism. They represent one of Mozambique’s main coastal assets, and coastal communities and the growing tourism industry rely mainly on reef-based resources. Today, about 6.6 million people live within Mozambique’s 48 coastal administrative districts. This represents 42% of the current population (15.7 million), which is expected to grow at 3% p.a. (INE, 1998). In 1994, the population density in coastal districts was 28 persons/km2. In 1996, much higher densities were recorded in the coastal...

The number of small commodity livestock slaughter plants in the Upper Northern Plains region continues to decline.  Significant factors contributing to this decline include:  1) pressure to consolidate, thereby capturing economies of scale; 2) relatively stringent federal inspection specifications, along with; 3) HACCP (Hazardous Analysis Critical Control Points) requirements. At the same time, consumer demand (markets) for specialty, selected, and exotic meats appears to be growing.  For example, the recent market successes in Europe evidenced by the North American Bison Cooperative based in New Rockford, North Dakota. Several alternative livestock producer groups have emerged which include lamb, ratite, elk, deer, goat, poultry, rabbit, specialty beef,...

Autores: Gonçalves, P.M.B.; Pereira, M.A.M.
The effects of human trampling on the population parameters of the soldier crab Dotilla fenestrata at Praia da Costa do Sol, Maputo were studied in two areas subjected to two different levels of human disturbance: (1) a low disturbance area; and (2) a high disturbance area. Sampling was carried out 1 day before and 1 day after disturbance took place and crab abundance and biomass data were compared between the two periods at each area. No significant differences (P &gt; 0.05) were found between abundance and biomass values before and after the disturbance. These results suggest that human trampling has an insignificant effect on D. fenestrata and that behavioral and habitat structure aspects might play more important roles on the population ecology of the...

The differences between the most recent complete treatment of this genus by Clausen (1938) and the present revision are, I think, of a rather fundamental nature. For, though Dr Clausen and myself agree that in the troublesome taxa, ‘the small number of characters .... has forced workers .... to base conclusions concerning species often on trivial details such as leaf cutting and size, characters which would not ordinarily be considered of fundamental importance in other groups’ (l.c. p. 5), from there on we have followed a different train of thought. Clausen stated (l.c. p. 6) that ‘If these characters were not adopted as criteria for species, it would be necessary to reduce the species to a very small number and thereby remove the opportunity to keep...

This study aimed to establish a standard dose and sample collection time for 13C phenylalanine and 13C-Dipeptide breath test in horses. To evaluate dose-dependent effects, healthy horses received 2.5 mg/kg, 5 mg/kg, and 10 mg/kg 13C phenylalanine dissolved in 1 ml/kg distilled water and 1.25 mg/kg, 2.5 mg/kg, and 5 mg/kg 13C dipeptide dissolved in 2 ml/kg distilled water. Tmax was observed during the sample collection time. For 13C phenylalanine, the standard deviation of Cmax at 5 mg/kg was lower than that of 10 mg/kg. For 13C dipeptide, the standard deviation of Tmax was the lowest at 5 mg/kg. This study revealed that an optimal dose for breath tests with 13C phenylalanine and 13C dipeptide may be 5 mg/kg in horses.

A preliminary study of communal nesting of Siberian flying squirrels Pteromys volans in Japan
Provedor de dados: Obihiro University of Agriculture and Veterinary Medicine Academic Repository (OAK)
Autores: Asari, Yushin; Yanagawa, Hisashi.
To maintain local populations of the Siberian flying squirrel Pteromys volans in restricted small habitats, it is necessary to understand their nesting and food biology. Communal nesting of P. volans is well documented in the Eurasian continent, but the details of this behavior have been poorly investigated in Japan. We investigated a group composition of P. volans in Hokkaido, Japan. The mean numbers of individuals using each nest box and tree cavity were 2.17 and 2.44, respectively. Although each female had its own exclusive home range, communal nesting composed by two females was observed in nest boxes. This result suggested that females frequently used nest boxes and formed same-sex groups in urban areas where nest resources might be scarce. Communal...

Autores: Fleury, Pierre-gildas; Mingant, Christian; Castillo, A.
In order to have a better understanding of recessing in great scallop, Pecten maximus and consequently the causes of mortality at reseeding, this study has monitored, at different seasons, the dispersion and recessing of different sizes of juveniles (about 15, 30 and 45 mm, called small, medium and large) after seeding. Moreover, the aim was to see when small spat (15 mm) could be seeded, and thus reduce the costs of intermediate culture. Three monitoring approaches were used together: (1) continual observations by remote video camera, of a defined area (less than 1 m2) containing 10 scallops from each size group; (2) daily monitoring of behaviour with divers along three bottom lines, with 20 × 1 m2 plots each and nine marked scallops per plot; and (3) the...

Autores: Coppejans, E.
This marine-phytosociological study of the two islands of Milos (1971) and Sikinos (1972), both belonging to the Cyclades, gives a general idea of the algal vegetation of the Aegean Sea. Comparative observations in the field as well as the analysis of many transects and the identification of collected material contributed to the recognition of some algal communities. The existence of other seasonal communities (especially winter ones) was indicated by the occurrence of a poor summer-aspect. Ecological requirements (such as light, exposure and slope) of the different algal communities were recorded and their vertical distribution was obtained from the transect data. Comparisons between these observations and conclusions were made with those of other authors...

To examine the origin of Callosciurus erythraeus introduced to Japan, we compared mitochondrial DNA control region sequences of eight haplotypes from Japan with those of 42 haplotypes from Taiwan. There were two distinct phylogroups in Japan. Six haplotypes from Japan were included in the Taiwan population, suggesting that they could have been introduced from Taiwan. Two haplotypes, however, were distantly related to the cluster consisting of all Taiwanese haplotypes and six Japanese haplotypes. The uncorrected genetic distances (5.2-5.7%) between these two haplotypes and the out-group (Callosciurus finlaysonii from Laos) were less than those (8.3-9.8%) between these two haplotypes and the cluster consisting of the other six Japanese haplotypes and all...

A preliminary survey of foliar sclerenchyma in neotropical Loranthaceae
Provedor de dados: Naturalis Digital Academic Repository
Autores: Kuijt, J.; Lye, D.
The foliar sclerenchyma of all genera of neotropical Loranthaceae is surveyed by means of cleared leaves, using selected species. Three general categories of sclerenchyma are recognized. Fibers may form discontinuous or continuous bundles associated with veins or, more rarely, occur as individual cells. Sclereids, often of the astrosclereid type, are present in varying concentrations, or may be absent. Cristarque cells are very common, and occasionally extremely abundant, but are lacking in several genera. The survey includes information on terminal tracheids which are almost invariably present. Attention is drawn to the systematic significance of sclerenchyma where warranted.

Autores: Puneet  K. Singh; Pratyoosh Shukla.
Saponins are extensively known for many biological activities e.g. antimicrobial, anti-palatability, anti-cancer and hemolytic. As cancer cells have a more cholesterol-like compound in their membrane structure the saponins bind cholesterol due to their natural affinity to bind cancer cell membrane. This prevents them from entering the body through the intestinal tract, where they have the ability to attach themselves to vital organs and grow. This study reports the effective use of lower dose saponins like immunotoxin so that they can inhibit the proliferation of cancerous pancreatic cells.

We used Markov chains to assess residence time, first passage time, rare of transfers between compartments, recycling index with a general mathematical formalism. Such a description applies to any flow-balanced system that can be modelled as a series of discrete stages or compartments through which matter flows. We derived a general set of equations from a probabilistic approach and applied them to a food web and a physical system derived from the literature. We therefore analysed preferential pathways of matter and behaviour of these systems and showed how it was possible to build up and exploit indices on the basis of a transition probability matrix describing the network, and to characterize with a generic algorithm: (1) the total indirect relationships...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pous, Stephane; Carton, Xavier; Lazure, Pascal.
A homogeneous shallow-water model with free surface is used to model the tidal circulation in the Persian Gulf. The numerical finite-difference model includes harmonic diffusion of horizontal momentum and quadratic bottom friction, it has a 9 km mesh size and it is forced by 7 tidal components at its southern boundary. High precision bathymetric data are used to obtain the bottom topography. The numerical model is run for more than a year. The results are the following: 1) The model accurately reproduces the tidal phase and amplitude observed at 42 tidal gauges in the region. This accuracy is attributed to the presence of the 7 components which are able to interact nonlinearly; 2) The amphidromic points are also well positioned by the model due to a proper...

A Process Study of the Wind-Induced Circulation in the Persian Gulf
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pous, Stephane; Carton, Xavier; Lazure, Pascal.
A shallow-water model, coupled with a three dimensional, hydrostatic ocean model, is used to study the wind induced circulation, and the Shatt-al-Arab river plume expansion, in the Persian Gulf. The models are used in an idealized configuration. The following results are obtained: 1) with northwesterly winds, a double gyre is formed: this gyre is cyclonic in the south and anticyclonic in the north. Southeastward currents flow along the Iranian and Arabian coast where the wind stress at the surface dominates the pressure gradient related to the free surface slope, and conversely in the deeper region of the Gulf; 2) In the eastern part of the Gulf, the cyclonic gyre intensifies, as observed and reported in the literature; 3) For northwesterly winds, the...

Provedor de dados: Ciência Rural
Autores: Ozelame,Odimar; Andreatta,Tanice.
O presente artigo aborda uma análise da produção de cereais em uma propriedade rural no município de Chapecó-SC. A coleta dos dados foi realizada considerando o cultivo da soja, do trigo e do milho, durante as safras 2008/2009, 2009/2010 e 2010/2011. Foram analisados os indicadores referentes aos custos de produção, indicadores técnicos e indicadores econômicos. Como resultado, identificou-se que os insumos são responsáveis pela maior parte dos custos nos três cultivos analisados, o cultivo da soja apresentou maior lucratividade, já o trigo apresentou prejuízo em duas safras agrícolas, das três consideradas. A lucratividade média no período foi significativa, mas o retorno do investimento pode ser considerado baixo (6,8% ao ano). Considerando o capital...

A production function analysis of commercial dairy farms in the Highlands of Eritrea using ridge regression
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ghebremariam,   W.K.; Ortmann,   Gerald F.; Nsahlai,   I.V.
This study presents a production function analysis of fresh milk production in the Highlands of Eritrea, where most dairy farmers in Eritrea are located. To ensure representative production functions, this region was divided into three relatively homogenous study areas, namely Central Zone, Mendefera and Dekemhare. Most data for the study were collected in a survey of 120 respondents using a structured questionnaire. To obviate the problem of multicollinearity among explainatory variables, ridge regression was used to estimate milk production functions for each study area. Production elasticities of variable inputs, marginal products (MPx), values of marginal products (VMPx), marginal rates of input substitution (MRS) and least-cost combinations of...

Autores: Scarano,Fabio Rubio; De Toni,Karen; Amarante,Cristiana Vasconcellos Goulart.
We have estimated the ISI-impact factor of Acta Botanica Brasilica for the past six years, calculated the journal's h-index, calculated the journal's self-citation, examined country and institutions of origin of the papers that cite Acta papers, and examined scope and profile of the most-cited papers published by the journal. Results demonstrated a steep rise in impact factor and citation frequency in 2008, which is most encouraging, but also revealed that the journal is below the level of maturity expected of a 20-year old journal. Visibility of the journal is mostly national although, surprisingly, journal's self-citation of 12% is fairly low. We use Acta as an example to discuss possible strategies to enhance the international visibility of botanical...

A PROFITABILITY ANALYSIS OF DAIRY FEEDING SYSTEMS IN THE NORTHEAST
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Winsten,   Jonathan R.; Parsons,   Robert L.; Hanson,   Gregory D.
This study analyzes the use and profitability of three distinct feeding systems; confinement feeding, traditional grazing, and management-intensive grazing from a randomly selected sample of northeastern dairy farms. The confinement feeding farms were significantly larger and produced more milk per cow, while the farms using management-intensive grazing incurred the lowest production costs.  Both confinement feeding and management-intensive grazing generated significantly higher rates of return to farm assets relative to farms using a mixed system. Multiple regression analysis confirms the critical importance of herd size, milk production per cow, debt level and veterinary expenses to farm profitability in all production systems.

ABSTRACT Reverse osmosis is the technology commonly used to produce fresh water from brackish groundwater. Due to the reject brine generated in desalination plants by reverse osmosis, vulnerability assessment to define critical areas to monitor waters from desalination has been an important tool for delineating the monitoring networks required for surveillance of potential salinization sites. The objective of this study was to assess the quality of waters sampled in desalination plants by a quality index, which provides a relative assessment of water vulnerability to potential salinization. The present study proposes an index to assess the quality of waters from desalination plants initially using the chemical parameters electrical conductivity, sodium...

This paper provides a methodology for the estimation of recreational demand functions and values using an ecoregional approach.  Ten ecoregions in the continental US were defined based on similarly functioning ecosystem characters. The individual travel cost method was employed to estimate the recreational demand functions for activities such as motorboating and waterskiing, developed and primative camping, coldwater fishing, sightseeing and pleasure driving, and big game hunting for each ecoregions.  Estimates of per trip net income value range from $12.93 to $218.38 while per day estimates range from $4.31 to $109.19.  While our ecoregional approach differs conceptually from previous work, our results appear consistent with the previous travel cost...

Autores: Dantas,Giordanni C.; Martins,Paula M.M.; Martins,Daniela A.B.; Gomes,Eleni; Ferreira,Henrique.
Abstract Citrus canker, caused by the Gram-negative bacterium Xanthomonas citri subsp. citri (Xac), is one of the most devastating diseases to affect citrus crops. There is no treatment for citrus canker; effective control against the spread of Xac is usually achieved by the elimination of affected plants along with that of asymptomatic neighbors. An in depth understanding of the pathogen is the keystone for understanding of the disease; to this effect we are committed to the development of strategies to ease the study of Xac. Genome sequencing and annotation of Xac revealed that ∼37% of the genome is composed of hypothetical ORFs. To start a systematic characterization of novel factors encoded by Xac, we constructed integrative-vectors for protein...

Autores: Brenha-Nunes,Marina R.; Contente,Riguel F.; Rossi-Wongtschowski,Carmen L.D.B.
ABSTRACT We present a protocol for measuring spatial variables in large (&gt;50 m2) soft-sediment tide pool. Secondarily, we present the fish capture efficiency of a sampling protocol that based on such spatial variables to calculate relative abundances. The area of the pool is estimated by summing areas of basic geometric forms; the depth, by taken representative measurements of the depth variability of each pool's sector, previously determined according to its perimeter; and the volume, by considering the pool as a prism. These procedures were a trade-off between the acquisition of reliable estimates and the minimization of both the cost of operating and the time spent in field. The fish sampling protocol is based on two con secutive stages: 1) two...

A proudman-function expansion of the m2 tide in the mediterranean-sea from satellite altimetry and coastal gauges
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sanchez, Bv; Ray, Rd; Cartwright, De.
An empirical model has been derived for the semidiurnal principal lunar tide M2 in the Mediterranean Sea, excluding the Aegean Sea. The work is primarily an exercise in combining satellite altimeter data with tide-gauge data, through the use of specially constructed spatial basis functions. The tide-gauge data consist of M2 harmonic constants previously derived at 43 chosen coastal locations. The altimeter data consist of approximately two years of Geosat data in the form of collinear differences of sea-surface heights, corrected for orbit error by adjusting long sequences of global data. The tide is expressed as an expansion in Proudman functions - numerically constructed, orthogonal eigenfunctions of the velocity potential. The most important mode is...

A putative resistant DNA marker for wool yellowing susceptibility in sheep
Provedor de dados: Genetics and Molecular Biology
Autores: Benavides,M.V.; Damak,S.; Maher,A.P.
An Australian Merino flock was screened for low (resistant) and high (susceptible) yellow predictive colour (YPC) breeding values in order to compare extreme individuals using the differential display of mRNA technique. One differentially expressed cDNA band was visualised only in the resistant group. This band showed no identity with the DNA sequences of public databases; however, they showed short homologies with three database sequences related to transmembrane signalling functions. The use of these candidate genes as DNA markers needs to be confirmed against sheep with a wide range of susceptibility to wool yellowing to verify the results.

A Pyranine based Procedure for Evaluation of the Total Antioxidant Potential (TRAP) of Polyphenols: A Comparison with closely related Methodologies
Provedor de dados: Biological Research
Autores: CAMPOS,ANA MARÍA; SOTOMAYOR,CARLOS PATRICIO; PINO,EDUARDO; LISSI,EDUARDO.
A novel procedure for the evaluation of total reactive antioxidant potentials (TRAP) is described. The method is based on the measurement of the bleaching of pyranine by peroxyl radicals. The addition of the antioxidants produces a clear induction time whose magnitude is directly related to the antioxidant concentration. A comparison of the values obtained with those reported employing closely related methodologies shows that the results are significantly affected by the substrate employed to monitor the steady state free radical concentration. Possible sources of this dependence are discussed

Autores: Cavalcanti,Silvana Maria de Morais; França,Emmanuel Rodrigues de; Magalhães,Marcelo; Lins,Ana Kelly; Brandão,Laura Costa; Magalhães,Vera.
Little is known about the etiology of progressive macular hypomelanosis, although it has been suggested that Propionibacterium acnes plays an important role. While microbiological culture is commonly employed to identify Propionibacterium acnes, new identification methods have been under investigation, amongst them polymerase chain reaction. To determine the cut-off point for the number of genome copies of Propionibacterium acnes in the lesional skin of patients with progressive macular hypomelanosis as a positive marker, employing quantitative real-time polymerase chain reaction and anaerobic culture, considered gold standard. An observational study with a comparison group, included 35 patients with dermatosis, attended at the Oswaldo Cruz University...

A Quantitative Assessment of the Morphological Characteristics of BeWo Cells as an in vitro Model of Human Trophoblast Cells
Provedor de dados: International Journal of Morphology
Autores: Abaidoo,C.S; Warren,M. A; Andrews,P. W; Boateng,K. A.
In order to study the detailed morphology of trophoblast cells during human implantation, BeWo cells were cultured as spheroids in suspension culture. These cultures were then processed for light and electron microscopical examination. The present study showed that the BeWo spheroids consist of two cell types which are cytotrophoblast-like and syncytiotrophoblast-like. The cells with larger nuclear diameter made up only about 1% of the cell population and appear to be those of syncytiotrophoblast. Therefore the predominant cell type of the BeWo spheroids appeared to be relatively undifferentiated and cytotrophoblast-like. About 10% of the BeWo cells in the present study were mitotic, indicating a highly proliferative population. Total cell number increased...

A quantitative estimation of the energetic cost of brown ring disease in the Manila clam using Dynamic Energy Budget theory
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Flye Sainte Marie, Jonathan; Jean, Fred; Paillard, Christine; Kooijman, Sebastiaan.
Brown ring disease (BRD) in the Manila clam, Ruditapes philippinarum, is a bacterial disease caused by the pathogen Vibrio tapetis. This disease induces the formation of a characteristic brown conchiolin deposit on the inner shell and is associated with a decrease in condition index indicating that the development of the disease affects the energy balance of the clam. A previous study showed that the energy budget of the host was affected by a decrease in filtration activity, and hypothesized that a second way to degrade the energy balance was the increase in maintenance costs associated to the cost of immune response and lesion repair. This paper focusses on this second way of degradation of the energy balance.  A starvation experiment confirmed that the...

A quantitative evaluation of the impact of beam trawling on benthic fauna in the southern North Sea
Provedor de dados: Open Marine Archive
Autores: Piet, G.J.; Rijnsdorp, A.D.; Bergman, M.J.N.; van Santbrink, J.W.; Craeymeersch, J.A.; Buijs, J.
Data on density of benthos species and on direct mortality caused by the passing of a beam trawl, together with fishing effort data for the Dutch beam-trawl fleet, were used to evaluate the annual population mortality caused by beam trawling in the Dutch sector of the North Sea. The effects of using environmental strata, instead of ICES rectangles for density distributions, and of using higher-resolution fishing-effort data on the population mortality estimates of 21 infauna and epifauna species were investigated. Variation in species abundance was markedly smaller based on sediment-depth strata than based on ICES rectangles, and the resulting population mortality estimates differed significantly among species (ratio ranged from 0.3 to 1.6) depending on...

A quantitative model for efficient construction of lentiviral vectors with a unique clone site
Provedor de dados: Nature Precedings
Autores: Gang Zhang; Anurag  Tandon.
Lentiviral vectors (LVs) were a powerful tool for transgene expression in vivo and in vitro. However, the construction of LVs is of low efficiency, due to the large sizes and lack of proper clone sites. Therefore, it is critical to develop efficient strategies for cloning LVs. Here, we reported a combinatorial strategy to efficiently construct LVs using EGFP, hPlk2 wild type (WT) and mutant genes as inserts. Firstly, site-directed mutagenesis (SDM) was performed to create BamH I site for the inserts; secondly, pWPI LV was dephosphorylated after BamH I digestion; finally, the amounts and ratios of the insert and vector DNA were optimized to increase monomeric ligation. Our results showed that the total percentage of positive clones was approximately...

A Quantitative Model for Human Olfactory Receptors
Provedor de dados: Nature Precedings
Autores: Sk. Sarif  Hassan; Pabitra  Pal Choudhury; Aritra Bose.
A wide variety of chemicals having distinct odors are smelled by humans. Odor perception initiates in the nose, where it is detected by a large family of olfactory receptors (ORs). Based on divergence of evolutionary model, a sequence of human ORs database has been proposed by D. Lancet et al (2000, 2006).  It is quite impossible to infer whether a given sequence of nucleotides is a human OR or not, without any biological experimental validation. In our perspective, a proper quantitative understanding of these ORs is required to justify or nullify whether a given sequence is a human OR or not. In this paper, all human OR sequences have been quantified, and a set of clusters have been made using the quantitative results based on two different metrics. Using...

A quantitative PCR approach for determining the ribosomal DNA copy number in the genome of Agave tequila Weber
Provedor de dados: Electronic Journal of Biotechnology
Autores: Rubio-Piña,Jorge; Quiroz-Moreno,Adriana; Sánchez-Teyer,L. Felipe.
Background: Agave tequilana has a great economic importance in Mexico in order to produce alcoholic beverages and bioenergy. However, in this species the structure and organization of the rDNAs in the genome are limited, and it represents an obstacle both in their genetic research and improvement as well. rDNA copy number variations per eukaryotic genome have been considered as a source of genetic rearrangements. In this study, the copy number of 18S and 5S rDNAs in the A. tequilana genome was estimated, and an absolute quantitative qPCR assay and genome size was used. In addition, an association between the rDNAs copy number and physical mapping was performed to confirm our results. Results: The analysis were successfully applied to determine copy number...

A quantitative study of the influence of coprocessing of binders on the mechanical properties of paracetamol tablets
Provedor de dados: Brazilian Journal of Pharmaceutical Sciences
Autores: Ogunjimi,Abayomi Tolulope; Alebiowu,Gbenga.
A 2³ factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing of binders on the mechanical properties. The results obtained from this study suggest that the nature (i.e. plastic/elastic) and ratio of binders coprocessed together alter the influence of C and P on TS and BFI.

A quantitative x-ray diffraction inventory of volcaniclastic inputs into the marine sediment archives off Iceland: a contribution to the Volcanoes in the Arctic System programme
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Andrews, John T.; Kristjansdottir, Greta B.; Eberl, Dennis D.; Jennings, Anne E.
This paper re-evaluates how well quantitative x-ray diffraction (qXRD) can be used as an exploratory method of the weight percentage (wt%) of volcaniclastic sediment, and to identify tephra events in marine cores. In the widely used RockJock v6 software programme, qXRD tephra and glass standards include the rhyodacite White River tephra (Alaska), a rhyolitic tephra (Hekla-4) and the basaltic Saksunarvatn tephra. Experiments of adding known wt% of tephra to felsic bedrock samples indicated that additions &gt;= 10 wt% are accurately detected, but reliable estimates of lesser amounts are masked by amorphous material produced by milling. Volcaniclastic inputs range between 20 and 50 wt%. Primary tephra events are identified as peaks in residual qXRD glass wt%...

A quarter of a century of Australian agricultural economics -  some personal reflections
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gruen,   Fred H.G.
The late Fred Gruen (1921–1997) was asked to write these previously unpublished reflections for the twenty‐eighth Annual Conference of the Australian Agricultural Economics Society in 1984; they were circulated in working paper format as Gruen (1986). In this paper, Fred, who made the transition from agricultural to general economics later in his career, offers a modest perspective on his contributions to agricultural analysis and policy. The unifying theme in this outstandingly productive life was his focus on public policy issues whose resolution would impact importantly on the lives of many — that is, his intellectual curiosity was driven ultimately by his philanthropy.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Throsby,   C.D.; Rutledge,   David J.S.
Several farm sector econometric models are reviewed initially and the aggregation problem highlighted. A thirty-equation model of the Australian agricultural sector is specified in which farm output, stocks and exports and the domestic demand for farm products are endogenous, as well as farm, export and retail prices. Disaggregation is into food and non-food components of unprocessed output, and the processing of food is traced through to final demand. The model is estimated by a modified 2SLS procedure using quarterly data covering the period 1960-1970.

A questão ambiental na origem do problema agrário brasileiro e o caso da região Sul.
Provedor de dados: Organic Eprints
Autores: Nascimento, Humberto Miranda do.
A especificidade do processo de apropriação privada de terras públicas no Brasil, após 1850, é o ponto de origem dos problemas ambientais atuais no espaço rural, isso porque foi desse período em diante que a ausência de limites ambientais se tornou a regra principal da aliança entre a concentração fundiária e o progresso técnico aplicado à agricultura, comprometendo dramaticamente outras formas de acesso, bem como o uso produtivo ou não produtivo das terras e seus recursos naturais. O estudo de caso realizado na região sudoeste do Paraná, no Sul do Brasil, no entanto, demonstra que, apesar de uma estrutura agrária mais democrática, a regra de ausência de limites ambientais também é reiterada. Naquela região, o impulso básico à degradação ambiental deve-se...

A question of rank: DNA sequences and radula characters reveal a new genus of cone snails (Gastropoda: Conidae)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Puillandre, Nicolas; Tenorio, Manuel J.
Molecular phylogenies of cone snails have revealed that the c. 350 sequenced species are divided into four main lineages, Conus, Conasprella, Californiconus and Profundiconus. In a recent study, minute species (less than 8 mm) were for the first time included in a molecular phylogenetic tree and were shown to correspond to deep lineages, of similar status to the four previously recognized, and sister group to Californiconus. They were attributed to the available generic names Lilliconus and Pseudolilliconus. In this article, we analyse, using morphological (shell and radula) and molecular characters (cox1 gene), several species of minute cone snails, and we conclude that the species considered as Pseudolilliconus in the previous study should actually be...

Autores: Moraes Junior,Edsel Amorim; Chiarello,Adriano Garcia.
From August 2001 to July 2002 the home range and movements of seven Micoureus demerarae (Thomas, 1905) (three males and four females) were investigated using radio tracking in the União Biological Reserve, state of Rio de Janeiro, south-eastern Brazil. A total of 436 locations was obtained and home range estimated with fixed Kernel (95% of data points), and minimum convex polygon (MCP) methods, with 100 and 95% of data points. Male home ranges estimated by MCP (100%) ranged from 5.4-24.2 ha and females from 0.3-10.7 ha. Corresponding figures calculated with Kernel (95%) were 4-10.9 ha for males and 1.3-5.9 ha for females. Animals travelled on average 423 m/night, with males travelling significantly further (582.8 m/night) than females (335.1 m/night) (t...

A radiographic method to estimate lung volume and its use in small mammals
Provedor de dados: Biological Research
Autores: CANALS,MAURICIO; OLIVARES,RICARDO; ROSENMANN,Mario.
In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V*L = 0.496 · V RX &amp;#8776; 1/2·V RX , where V RX is a measurement obtained from the x-ray that represents the volume of a rectangular box containing the lungs and mediastinum organs. The proposed formula may be interpreted as the volume of an ellipsoid formed by both lungs joined at their bases. When that relationship was used to estimate lung volume, values similar to those expected from allometric relationship were found in four rodents. In two others, M. musculus and R. norvegicus, lung volume was similar to reported data, although...

A rainfall simulation study on the relationships between soil test P versus dissolved and potentially bioavailable particulate phosphorus forms in runoff
Provedor de dados: Organic Eprints
Autores: Uusitalo, Risto; Aura, Erkki.
Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, calling for other ways to predict them. Such predictions could be based on soil loss and available soil P indices, e.g., agronomic P status. To study correlations between P pools in runoff versus soil P saturation (by Mehlich 3 extraction; DPSM3) and acetate soil test P (PAc), 15 clayey soils of south Finland were subjected to laboratory rainfall simulation. Runoff from these simulations was analyzed for concentrations of suspended soil (TSS), dissolved molybdate-reactive P (DRP), total P (TP), and, as normalized to soil loss, potentially bioavailable forms of...

A serosurvey was conducted to estimate the prevalence of bovine brucellosis in the State of Paraíba, Brazil. A random sample of six municipalities was selected from each of three ecoregions of the State: the Agreste/Litoral region (1), the Cariri/Curimatau region (2) and the Sertão region (3). These 18 municipalities were divided in quadrants and one herd was selected at random from each quadrant. The sampling scheme included herds with more than 50 bovines, which excludes small-holder subsistence livestock production. At least 32 animals were sampled within each herd, stratified in four age categories, as follows: (1) at least 8 animals under 6 months of age, (2) at least 8 animals of 7 to 18 months of age, (3) at least 8 animals of 19 to 30 months of age...

A randomized controlled trial to compare the use of homeopathy and internal Teat Sealers for the prevention of mastitis in organically farmed dairy cows during the dry period and 100 days post-calving.
Provedor de dados: Organic Eprints
Autores: Klocke, P.; Ivemeyer, S.; Butler, G.; Maeschli, A.; Heil, F.
Introduction: Routine use of antibiotics to prevent mastitis in dairy cows is prohibited by organic farming regulations. Internal Teat Sealers have been proposed as an alternative. We compared two drying-off (DO) supporting measures (Internal Teat Sealer and Homeopathy) to an untreated control group to assess their protective effects against clinical mastitis and intra-mammary infections during dry period of dairy cows.  Methods: A field trial with 102 dairy cows from 13 Swiss organic dairy farms was conducted. Cows were randomly assigned to one of three groups within a herd. In the Internal Teat Sealer group (ITS; 36 cows) cows were treated with the commercial ORBESEAL (Pfizer) in all four quarters immediately after the last milking. In the Homeopathy...

Autores: Tahan,S.; Morais,M.B.; Wehba,J.; Scaletsky,I.C.A.; Machado,A.M.O.; Silva,L.Q.C.D.; Fagundes Neto,U.
The present study evaluated the effect of non-absorbable oral polymyxin on the duodenal microflora and clinical outcome of infants with severe infectious diarrhea. Polymyxin was chosen because classic enteropathogenic Escherichia coli was more sensitive to this antibiotic. Twenty-five infants were randomly assigned to a 7-day treatment with oral polymyxin (2.5 mg/kg in 4 daily doses) or placebo. Duodenal and stool cultures were performed before and after the treatment. Five patients were excluded during the study because of introduction of parental antibiotic therapy due to clinical sepsis (N = 3) or rapid clinical improvement (N = 2). In the polymyxin group, small bowel bacterial overgrowth occurred in 61.5% of the cases (8/13) before treatment and in...

A rapid alternative technique for obtaining silver-positive patterns in chromosomes
Provedor de dados: Genetics and Molecular Biology
Autores: Kavalco,Karine Frehner; Pazza,Rubens.
Silver nitrate chromosome staining to evidence nucleolar organizer regions (NORs) is a widely adopted methodology. The aim of the present work was to improve this technique, reducing the preparation time without decreasing the quality of the results. Microwave irradiation proved to be quite efficient and reliable for this purpose, as it allowed to identify Ag-NORs equivalent to those obtained by the conventional procedure and also to reduce the concentration of the employed reagents, as well as the precipitation of debris on the preparation.

A rapid method for measuring soil water content in the field with a areometer
Provedor de dados: Scientia Agricola
Autores: Calbo,Adonai Gimenez.
The availability of a rapid method to evaluate the soil water content (U) can be an important tool to determine the moment to irrigate. The soil areometer consists of an elongated hydrostatic balance with a weighing pan, a graduated neck, a float and a pynometric flask. In this work an areometer was adapted to rapidly measure soil water content without the need of drying the soil. The expression U = (M A - M AD)/(M M -M A) was used to calculate the soil water content. In this equation M M is the mass to level the areometer with the pycnometric flask filled with water, M A the mass to level the areometer with a mass M M of soil in the pycnometer, the volume being completed with water, and similarly M AD the mass added to the pan to level the areometer with...

A rapid method of extracting meiobenthic nematodes and copepods from mud and detritus
Provedor de dados: Open Marine Archive
Autores: Heip, C.H.R.; Smol, N.; Hautekiet, W.
The extraction of nematodes and harpacticoid copepods from muddy sediments or sediments containing a large amount of organic detritus can be achieved through a series of centrifugations of the material in a sacharose solution of at least 900 g/l. The number of individuals appearing in the supernatant after each centrifugation forms a geometric series, with a ratio which is dependent on the amount of material, the concentration of the saccharose solution, and the acceleration of the centrifuge. Knowledge of this ratio allows an estimation of density after only one centrifugation. More than 90 % of the animals present in the sample can be extracted after only two centrifugations.

Autores: Long, Marc; Tallec, Kevin; Soudant, Philippe; Lambert, Christophe; Le Grand, Fabienne; Sarthou, Geraldine; Jolley, Dianne; Hegaret, Helene.
Harmful microalgal blooms are a threat to aquatic organisms, ecosystems and human health. Toxic dinoflagellates of the genus Alexandrium are known to produce paralytic shellfish toxins and to release bioactive extracellular compounds (BECs) with potent cytotoxic, hemolytic, ichtyotoxic and allelopathic activity. Negative allelochemical interactions refer to the chemicals that are released by the genus Alexandrium and that induce adverse effects on the physiology of co-occurring protists and predators. Releasing BECs gives the donor a competitive advantage that may help to form dense toxic blooms of phytoplankton. However BECs released by Alexandrium minutum are uncharacterized and it is impossible to quantify them using classical chemical methods....

Autores: Campos,Mireille Guimarães Vaz de; Chauffaille,Maria de Lourdes L. Ferrari; Rodrigues,Celso Arrais; Krum,Everson A.; Yamamoto,Mihoko.
The Philadelphia chromosome is observed in 5% of pediatric acute lymphocytic leukemia (ALL) and in 25% to 50% of adult ALL cases, and is associated with poor prognosis. Double Ph in a hyperdiploid karyotype is common in chronic myeloid leukemia (CML), but rarely found in ALL. We report here the case of a girl diagnosed with ALL at 7 years of age. After treatment with the pediatric protocol BFM 83 for ALL, she stayed in continuous complete remission for nine years. At age 19, she was re-admitted with a white blood cell count of 6.8 x 10(9)/L with 3% blasts, and a platelet count of 65 x 109/L. Bone marrow aspirate showed 92.6% lymphoid blast cells, and chromosome analysis after G-banding revealed the karyotype...

Autores: Martins,Fábio Tadeu Arrojo; Ramos,Berenice Dias; Sartorato,Edi Lúcia.
Abstract HDR syndrome is a rare autosomal dominant disorder caused by mutations in the GATA3 gene and characterized by hypoparathyroidism, sensorineural deafness and renal abnormalities. Here we report a Brazilian family, from which the proband, his mother and his grandfather were diagnosed with bilateral sensorineural hearing loss. Molecular screening of the GJB2, GJB6 and MTRNR1 genes in the proband showed no alterations; however, whole exome sequencing detected a heterozygous mutation, c.1099C &gt; T (p.Arg367*), in the GATA3 gene. Segregation analyses showed that the mother also had the mutation, but not the grandparents, hence indicating a different hearing impairment type for the grandfather. Paternity test of the mother of the proband confirmed that...

Autores: Anu,Vinod Ranade; Rajalakshmi,Rai; Latha,Venkatraya Prabhu; Mangala,Kumaran.
An unusual presentation of the duplication of thoracic duct with a rare lymphatico- venous communication was found during the routine dissection for undergraduate students. The thoracic duct duplicated at the level of T12 vertebra. Normally thoracic duct opens into the junction of left internal jugular vein and subclavian vein. On the right side of the neck, the right lymphatic duct conveys the lymph from the head and neck, the upper extremity and the right side of the thorax to the right innominate vein. Here, the duplicated thoracic duct on the left side opened directly into the inferior vena cava. The above case is discussed with regard to its development, incidence, and clinical significance

A Rare Pattern of Brachial Artery Variation: Case Report
Provedor de dados: International Journal of Morphology
Autores: Jacomo,A. L; Martinez,C. A. R; Saleh,S. O; Andrade,M; Akamatsu,F. E.
Unlike the venous system, variations in arterial anatomy are less frequent and most of them affect visceral arteries. In limbs, variations of the brachial artery are the most reported and at least six different patterns have been described so far. The commonest is the superficial brachial artery which lies superficially to the median nerve. Much less prevalent are the high origin of the radial artery (brachioradial artery) or the existence of a doubled brachial artery (accessory brachial artery). We present a previously undescribed pattern of brachial artery variation. During dissection of the right upper limb of a 60 year-old male embalmed cadaver, we found the bifurcation of the brachial artery in the proximal portion of the middle third of the arm. Its...

Autores: Bernd-Souza,R.B.; Sa,M.F. Grossi de; Ellis,D.D.; McCown,B.H.
The effects of an animal RNase fused to the late cotton pollen-specific promoter G9 in a plant system were investigated. Expression of the chimeric genes G9-uidA and G9-RNase in tobacco plants showed that the 1.2-kb promoter fragment of the G9 gene was sufficient to maintain tissue and temporal specificity in a heterologous system. GUS (beta-glucuronidase) expression was detected only in pollen from anther stage 6 through anthesis, with maximal GUS activity in pollen from stage 10 anthers. Investigating the effects of the rat RNase on pollen viability at stage 10, we found that pollen viability was reduced from 79 to 8% and from 89 to 40%, in pollen germination and fluoresceine diacetate assays, respectively, in one G9-RNase transgenic line, suggesting a...

A Rate Distortion approach to protein symmetry

A spontaneous symmetry breaking argument is applied to the problem of protein folding, via a Rate Distortion analysis of the relation between genome coding and the final condensation of the protein molten globule. In the &amp;#x27;energy&amp;#x27; picture, the average distortion between codon message and protein structure, under constraints driven by evolutionary selection, serves as a temperature analog, so that low values limit the possible distribution of protein forms, producing the canonical folding funnel. A dual &amp;#x27;developmental&amp;#x27; perspective sees the rate distortion function itself as the temperature analog, and permits incorporation of chaperons or toxic exposures as catalysts, driving the system to different possible outcomes or...

A Real Options Analysis of Automatic Milking Systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Engel,   Phoebe D.; Hyde,   Jeffrey.
Automatic, or robotic, milking systems have the potential to significantly change the way milk is produced on U.S. dairy farms. However, there is a high degree of uncertainty associated with adoption of this new technology. A real options approach is used to analyze the decision to replace an operational milking system with an automatic milking system. The most important source of uncertainty is shown to be the length of the technology's useful life. Under our assumptions, the automatic system is always an optimal investment if it is certain that it will last longer than the operational system being replaced.

A realizable force feedback-feedforward control loop for a piston wave absorber
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Maisondieu, Christophe; Clément, Alain.
We consider the problem of the absorption of 2D water waves by the horizontal motions of a vertical plane in response to the hydrodynamical force it experiences. The solution of this problem is straightforward in the frequency domain. Unfortunately, the transposition of the frequency domain solution to the time domain by inverse Fourier transforming leads to a non-causal impulse response function. Thus it cannot be used just as it is, neither as a control loop for physical absorbing devices nor as a non radiating boundary condition (NRBC) in numerical modeling. In this paper, we propose a method to derive causal approximations of this ideal controller. Two time-domain absorbing relations are proposed, differing in whether or not one knows a dominant...

A real-time PCR genotyping assay to detect FAD2A SNPs in peanuts (Arachis hypogaea L.)
Provedor de dados: Electronic Journal of Biotechnology
Autores: Barkley,Noelle A; Wang,Ming Li; Pittman,Roy N.
The high oleic (C18:1) phenotype in peanuts has been previously demonstrated to result from a homozygous recessive genotype (ol1ol1ol2ol2) in two homeologous fatty acid desaturase genes (FAD2A and FAD2B) with two key SNPs. These mutant SNPs, specifically G448A in FAD2A and 442insA in FAD2B, significantly limit the normal function of the desaturase enzyme activity which converts oleic acid into linoleic acid by the addition of a second double bond in the hydrocarbon chain. Previously, a genotyping assay was developed to detect wild type and mutant alleles in FAD2B. A real-time PCR assay has now been developed to detect wild type and mutant alleles (G448A) in FAD2A using either seed or leaf tissue. This assay was demonstrated to be applicable for the...

A reappraisal of the systematics of the Monocelididae (Platyhelminthes, Proseriata): inferences from rDNA sequences
Provedor de dados: Open Marine Archive
Autores: Litvaitis, M.K.; Curini-Galletti, M.C.; Martens, P.M.; Kocher, T.D.
The current classification system for the Monocelididae which is based on the character "presence or absence of an accessory prostatoid organ" divides the family into two subfamilies, namely the Minoninae and the Monocelididinae. However, other characters relating to the structure of the male copulatory bulb and to karyotypes do not support this division. Monocelidid male copulatory bulbs can be either of the simplex or the duplex-type, and if this character is mapped onto the current classification, then both subfamilies contain species with either type of copulatory bulb. We therefore decided to construct an independent phylogeny for the Monocelididae using nucleotide-sequence data of the gene coding for the 26/28S rDNA. Distance and parsimony-based...

A reappraisal of the vital effect in cultured benthic foraminifer Bulimina marginata on Mg/Ca values: assessing temperature uncertainty relationships
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Wit, J. C.; De Nooijer, L. J.; Barras, C.; Jorissen, F. J.; Reichart, G. J.
The reconstruction of past temperatures is often achieved through measuring the Mg/Ca value of foraminiferal test carbonate. The diversity in foraminiferal Mg/Ca-temperature calibrations suggests that there is also a biological control on this proxy. This study presents a new Mg/Ca-temperature calibration for the benthic foraminifer Bulimina marginata, based on cultures under a range of temperatures (4-14 degrees C). Measured Mg/Ca values for B. marginata correlate with temperature (Mg/Ca = (1.10+/-0.10) e((0.045+/-0.009)) T, R-2 = 0.28 p &lt; 0.01). The inter-individual variability is, however, also significant (standard deviation is 10-35% of the average). Before applying this or any calibration, the effect of the inter-individual variability on the...

Autores: Dennis, R.W.G.
A study of the sole original species of Belonidium Mont. &amp; Dur. revealed that this generic name has been misapplied by subsequent authors. The taxon is redefined as a subgenus of Dasyscyphus S. F. Gray. A brief account is given of the latter genus and its subdivisions and of other genera assigned to the Hyaloscyphaceae trib. Lachneae ( Psilachnum Höhn., Diplocarpa Massee) and subfam. Trichocyphelloideae ( Lachnellula P. Karst., Perrotia Boud.) transferred from the Helotiaceae to the Hyaloscyphaceae, as well as of some other genera, Trichodiscus Kirschst., Lasiobelonium (Sacc.) Sacc. and Zoellneria Vel. The taxonomic significance of lanceolate paraphyses, characteristic in the Hyaloscyphaceae of the Lachneae, and in other families of Helotiales is...

The Recent and Fossil species of &lt;i&gt;Paralimnocythere&lt;/i&gt; are reassessed and the genus is characterized using both soft part and valve morphology. Seventeen species, of which eleven have living representatives, are here retained. &lt;i&gt;Relictocytherina&lt;/i&gt; Negadaev-Nikonov, 1968 is confirmed as a synonym of &lt;i&gt;Paralimnocythere; R. orginalis&lt;/i&gt; (Negadaev-Nikonov, 1965), the type species is furthermore synonymous with &lt;i&gt;P. relicta&lt;/i&gt; (Lilljeborg, 1863). &lt;i&gt;Paralimnocythere psammmophila&lt;/i&gt; (Flössner, 1965) and &lt;i&gt;P. compressa&lt;/i&gt; (Brady &amp; Norman, 1889) are both reinstated as valid species, quite different from &lt;i&gt;P. relicta&lt;/i&gt;.

A recombination point is conserved in the mitochondrial genome of higher plant species and located downstream from the cox2 pseudogene in Solanum tuberosum L.
Provedor de dados: Genetics and Molecular Biology
Autores: Tada,Susely F.S.; Souza,Anete P.
The potato (Solanum tuberosum L.) mitochondrial cox3/sdh4/pseudo-cox2 gene cluster has previously been identified by heterologous hybridization using a Marchantia polymorpha sdh4 probe. In our present study we used Southern blotting using sdh4 and cox2 probes to show that the sdh4 and cox2 genes are clustered in the mitochondria of potato, soybean and pea. Northern blotting revealed cotranscription of sdh4 and cox2 in potato but not in cauliflower, indicating that these genes are not clustered in cauliflower. A putative recombination point was detected downstream of the cox2 pseudogene (pseudo-cox2) in potato mitochondrial DNA (mtDNA). This sequence corresponds to a 32 bp sequence which appears to be well-conserved and is adjacent to the terminals of some...

A reconnaissance of the genus Pseudobaeospora in Europe II
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bas, C.
In the second and last part of this paper the genus Pseudobaeospora is redefined, its taxonomic position is discussed, and the possibilities of a formal infrageneric classification are considered. Because of the recent discovery of another new species, viz. P. mutabilis Adamčík &amp; Bas, emendations of the key published in the first part of this paper (Bas, 2002), are proposed. Descriptions and drawings of all European taxa known are presented. Extralimital species are discussed and compared with European species. With the rapid increase in the number of species of the genus Pseudobaeospora in Europe from one or two ‘classical’ ones before 1995 to 14 to 16 species at present, also the morphological diversity of the genus has increased considerably....

A Reconsideration of Environmental Federalism
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Oates,   Wallace E.
This paper provides a review and assessment of the debate over environmental federalism-the issue of the roles of different levels of government in environmental management. The paper begins with the presentation of three benchmark cases that provide a framework for thinking about the issue. It then offers a review, first of the theoretical literature and second of some new, provocative empirical literature on the race to the bottom. The paper contends that there remains, under certain circumstances, an important role for decentralized government in the setting of environmental standards and the design of regulatory programs. The central government, in addition to setting standards for "national" pollutants, has a fundamental contribution to make in...

A record from Surinam of the bat Chiroderma trinitatum Goodwin, 1958 (Mammalia, Chiroptera)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bergmans, W.
Re-examination of a collection of bats from Surinam in the Zoölogisch Museum, Amsterdam, uncovered a specimen representing the Phyllostomatid bat Chiroderma trinitatum Goodwin, 1958. This species does not appear in the monograph of the Chiroptera of Surinam by Husson (1962), nor in his more recent works on the mammals of that country (1973; 1978). The present specimen therefore seems to be the first record from Surinam. It is a young adult female, captured after it had flown into a house at night on 1-II-1967, by H. Nijssen at Ligorio, a village on the river Gran Rio about 16 km southwest of Djoemoe in the Brokopondo District. It has been preserved in alcohol, with extracted skull, and is registered as ZMA 10.136.  IDENTIFICATION In a recent paper dealing...

Autores: Gaxiola, Gabriela; Gallardo, Pedro; Simoes, Nuno; Cuzon, Gerard.
Red shrimp, Farfantepenaeus brasiliensis, larvae's response to different concentrations of live foods (diatoms Chaetoceros gracilis: 20-100 x 103 cells/mL; flagellate Tetraselmis chuii: 2-10 x 103 cells/mL and Artemia nauplii [NA]: 1-5 NA/mL) was investigated in three experiments. Experimental assessments were based on four variables: survival rate, weight gain, development index (DI), and resistance to salinity stress. A combination of C. gracilis 80 x 103 cells/mL, T. chuii 2 x 103 cells/mL, and Artemia 4 NA/mL provided the best experimental response. Specifically, F. brasiliensis larvae fed with the above-mentioned optimal concentrations of microalgae and Artemia grew faster and reached the postlarval stage in less time (168 h) than larvae in other...

A redefinition of Gastonia and related genera (Araliaceae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Philipson, W.R.
The six genera Gastonia, Tetraplasandra, Reynoldsia, Munroidendron, Peekeliopanax, and Indokingia form a natural complex distributed from East Africa to the Marquesas and the Hawaiian Islands. The characters which have been thought useful in distinguishing these genera are re-examined. The distinction between Gastonia and Tetraplasandra is redefined, emphasis being placed on the radiating stigmatic arms in the fruit rather than on pleiomery of the stamens. On this basis Tetraplasandra is confined to the Hawaiian group. The monotypic genera Peekeliopanax and Indokingia are reduced to synonymy under Gastonia, which thus comprises all species of the complex west of Samoa.

Abstract Antispastis Meyrick, 1926 is a poorly known genus of leaf-mining micromoths endemic to the Neotropics, with still uncertain taxonomic position within the Yponomeutoidea. In the present study, the egg, larva and pupa of A. clarkei Pastrana, previously known only from Argentina, are described and illustrated with the aid of optical and scanning electron microscopy. Data on life history, including histology of the mine, are also provided. Family placement of the genus is reassessed based on comparison of morphology and DNA sequences with closely related lineages. The larvae form blotch mines on the upper surface of Solanum L. (Solanaceae) leaves, feeding on palisade parenchyma in all instars. Pupation occurs outside the mine, in an inverted...

Autores: Huys, R.
&lt;i&gt;Caligopsyllus primus&lt;/i&gt; Kunz, 1975, reported from tidal pools near East London (South Africa), is redescribed and figured on the basis of type material. An amended diagnosis of the genus &lt;i&gt;Caligopsyllus&lt;/i&gt; Kunz, 1975 is presented. Cladistic analysis falsified the hypothesis of a close relationship between &lt;i&gt;Caligopsyllus&lt;/i&gt; and &lt;i&gt;Kliopsyllus&lt;/i&gt; Kunz, 1962, favouring instead a link with &lt;i&gt;Apodopsyllus&lt;/i&gt; Kunz, 1962. The morphological modifications are discussed within the context of a possible ecto-associated life-style. Finally, a standard format of abbreviations and terminology is proposed for the paramesochrid caudal ramus.

A re-evaluation of evidence raises questions about the fasting migration hypothesis for Swainson's Hawk (Buteo swainsoni)
Provedor de dados: El Hornero
Autores: Bechard,Marc J.; Sarasola,Jose H.; Woodbridge,Brian.
We examined the fasting migration hypothesis for Swainson's Hawks (Buteo swainsoni) by estimating the length, duration, and speed of the migration between North and South America and measuring changes in their body masses at various times throughout the year. We instrumented 34 adult Swainson's Hawks with satellite radios on their breeding grounds in western North America to determine the duration, length, and speed of the migration. Migrating south at 188 km/day, it took Swainson's Hawks 51 days to complete their 13504 km migration to their austral summer grounds. Averaging only 150 km/day on their return migration, it took them 60 days to complete the shorter 11952 km migration back to North America. Adult male and female Swainson's Hawks had average...

A re-evaluation of marine nematode productivity
Provedor de dados: Open Marine Archive
Autores: Vranken, G.; Herman, P.M.J.; Vincx, M.; Heip, C.H.R.
Nematodes are the most abundant multicellular animals in marine sediments but their role in the benthos has not been properly quantified yet. In nearly all energy-flow budgets of marine systems their annual production P is given as about nine times their biomass B and their part in the total energy-flow is consequently estimated as anywhere between 3 and 30% of the total (carbon) input in the benthic system. Our laboratory experiments demonstrate that nematode productivity is much higher than P/B ~ 9 per year and may reach values of over 60 for bacterial grazers. To obtain more reliable estimates for field populations we propose a regression equation relating egg-to-egg development time T&lt;sub&gt;min&lt;/sub&gt; to temperature (t) and adult female weight...

Three main drainage basins debouch into the bay, providing a mean freshwater discharge of 200 m³/s (prior to 1985), or less than 1% of the spring tidal discharge through the bay mouth. Based on the result of several sedimentological studies performed in the 1970's, five surface sedimentary facies were identified inside the bay, namely i) transgressive siliciclastic marine sand facies; ii) transgressive bay sand-mud facies; iii) a transgressive carbonate marine sand facies; iv) regressive bay-mud facies, and v) regressive fluvial sand facies.

A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Uri,   Noel D.; Hyberg,   Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

Autores: Martins , José de Souza.
Já no primeiro mandato do presidente Fernando Henrique Cardoso, a política agrária sofreu reorientações significativas, que marcariam seu segundo mandato, a partir da nomeação de Raul Jungmann como ministro do Desenvolvimento Agrário. A reforma agrária finalmente encontrou o seu sujeito, a agricultura familiar, e o Estado encontrou a sua missão agrária como gestor do território. Foram assim estabelecidas as bases concretas para o exercício da função social da propriedade, recuperando o Estado, na prática, o domínio eminente do território do país. Importante providência nesse sentido foi a anulação dos títulos irregulares de propriedade de sessenta milhões de hectares de terra. O governo firmou a prerrogativa do Estado de "rotinizar" a redistribuição da...

O corte e queima são um dos tipos de perturbação predominante na floresta Atlântica montana no Sudeste do Brasil. A análise de uma cronosseqüência de regeneração (10, 18, 40 anos e floresta madura) corrobora a hipótese de que as características da floresta se transformam em diferentes velocidades em direção aos valores observados na floresta madura. Em ordem decrescente de velocidade, a floresta, após corte e queima, restaura a riqueza e a diversidade de espécies arbóreo-arbustivas, a composição de guildas, a composição florística (importância relativa das famílias) e, por último, os atributos da estrutura física, com exceção da densidade de indivíduos.

A regional analysis of CAP expenditure in Austria
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Strahl,   Wibke; Dax,   Thomas; Hovorka,   Gerhard.
This paper reflects the demand for taking account of the territorial dimension in the application of Common Agricultural Policy (CAP) more comprehensively. While this has been addressed in rural development discourse to a wide extent over the last two decades and consensus for regionalized strategies is emerging, programme evaluation is in general still limited to the analysis of policy interventions at the national level. This implies that conclusions on the territorial effects of CAP are largely missing. Therefore the intention of this paper is to provide a regional analysis of CAP expenditures for pillar 1 and pillar 2, and to demonstrate and assess their actual territorial impacts, represented on the basis of the NUTS 3 region ‘Obersteiermark West’:...

These programs seek to adjust production to utilization on a year-to-year basis by offering incentives to producers to expand or contract their crop planting.  As a result, accurate estimates of producer response to changing market prices and government programs are very important for policy makers as they attempt to adjust programs to balance demand and supply.  Good forecasts of future crop acreages can also help economists provide producers and agribusinesses with better guides for strategies and planning, marketing, and production decisions.  The objective of this study is to forecast acreage planted for a specific...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dong,   Fengxia; Lu,   Jing; Du,   Xiaodong.
CHINA is currently the world largest emitter of energy-related carbon dioxide (CO2). Understanding the driving forces governing CO2 emission levels and their evolutions in China can provide useful information for policy makers who aim to reduce green house gas emissions. Because of policy and historical reasons, considerable regional growth and income disparities exist in China. The regional disparities may influence energy use and CO2 emissions. Therefore, this study is to investigate the driving forces governing CO2 emission levels and their evolutions at regional level in China.

A REGIONAL EQUILIBRIUM ANALYSIS OF THE WELFARE IMPACT OF CASH TRANSFERS: AN ANALYSIS OF PROGRESA IN MEXICO
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Coady,   David P.; Harris,   Rebecca Lee.
Using a regionally disaggregated computable general equilibrium model, we analyze the differential welfare impacts of a cash transfer program targeted at rural areas. The direct effect of the transfers decreases regional income differentials, but the indirect effects depend on how the program is financed. Financing the program with a more efficient tax system is also less regressive and has favorable urban impacts. The less efficient instruments result in relatively higher incomes in all rural regions, but are more regressive. The increasing share of urban poverty highlights the shortcomings of rural targeting and raises the issue of horizontal equity.

Autores: Silva,Elisângela Benedet; Giasson,Élvio; Dotto,André Carnieletto; Caten,Alexandre ten; Demattê,José Alexandre Melo; Bacic,Ivan Luiz Zilli; Veiga,Milton da.
ABSTRACT The success of soil prediction by VIS-NIR-SWIR spectroscopy has led to considerable investment in large soil spectral libraries. The aims of this study were 1) to develop a soil VIS-NIR-SWIR spectroscopy approach using legacy soil samples to improve spectral soil information in a regional scale; (2) to compare six spectral preprocessing techniques; and (3) to compare the performance of linear and non-linear multivariate models for prediction of sand and clay content. A total of 1,534 legacy soil samples, stored by Epagri, were collected from agricultural areas in 2009 on a regional scale, covering 260 municipalities of Santa Catarina. Six spectral preprocessing techniques were applied and compared with reflectance spectra (control treatment) in...

A regionally scalable habitat typology for assessing benthic habitats and fish communities: Application to New Caledonia reefs and lagoons
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pelletier, Dominique; Selmaoui‐folcher, Nazha; Bockel, Thomas; Schohn, Thomas.
Scalable assessments of biodiversity are required to successfully and adaptively manage coastal ecosystems. Assessments must account for habitat variations at multiple spatial scales, including the small scales (&lt;100 m) at which biotic and abiotic habitat components structure the distribution of fauna, including fishes. Associated challenges include achieving consistent habitat descriptions and upscaling from in situ‐monitored stations to larger scales. We developed a methodology for (a) determining habitat types consistent across scales within large management units, (b) characterizing heterogeneities within each habitat, and (c) predicting habitat from new survey data. It relies on clustering techniques and supervised classification rules and was...

A implementação, em nível nacional, da Convenção sobre Diversidade Biológica, especialmente dos artigos 8j e 15, que tratam respectivamente do conhecimento tradicional e do acesso aos recursos genéticos e da repartição dos benefícios provenientes da sua utilização, tem gerado intenso debate quanto ao seu impacto sobre a pesquisa. No Brasil vigora atualmente a Medida Provisória 2.186-16/01 (MP) que instituiu as regras para o acesso a e a remessa de componentes do patrimônio genético e o acesso a conhecimentos tradicionais associados. Essa norma previu a criação da autoridade nacional competente o Conselho de Gestão do Patrimônio Genético (CGEN) no âmbito do Ministério do Meio Ambiente, o qual iniciou suas atividades em abril de 2002.

Understanding of antimicrobial defence mechanisms of penaeid shrimp should help in the design of efficient strategies for the management and disease control in aquaculture. In this study, we have specifically analysed the expression in circulating hemocytes of antimicrobial peptides (AMPs) encoding genes, such as PEN2 and PEN3, ALF, crustin, lysozyme and a putative cysteine-rich peptide. We evidenced a relationship between the level of expression of some AMPs and the successful response of the shrimp, Litopenaeus stylirostris, to circumvent a pathogenic Vibrio penaeicida infection. Additionally, significant differences in some AMP transcript amounts are evidenced between control, non-selected shrimp line and the third generation breeding of shrimp selected...

A relationship between deep-sea benthic oxygen demand and oceanic primary productivity
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Christensen, Jp.
A diagenetic model of porewater O-2 was used to examine the relationship between organic carbon flux to the sediments and benthic oxygen demand (BOD). The model predicted that the organic carbon influx to sediments balances BOD as long as sediments are oxygenated. The critical rate occurs when O-2 at infinite depth disappears. With influxes exceeding the critical rate, the O-2 flux into the sediments via molecular diffusion can not consume all incoming organic matter, and anaerobic conditions result in BOD underestimating the carbon influx. Given that low rates of deep-sea BOD approximate the carbon influx below 9 g.C.m(-2).y(-1), a significant multilinear regression was found between published BOD, primary productivity (P-p, both in g.C.m(-2).y(-1))(,)...

O fenômeno da pluriatividade passou a ser mais estudado no Brasil na década de 1990, quando foram publicados trabalhos em todas as regiões do país. Um dos elementos centrais desta discussão diz respeito à unidade de análise relevante para se analisar a complexidade desse fenômeno. Em consonância com a literatura internacional, este artigo defende a idéia de que a família, e não a unidade de produção, deve ser o elemento balizador de estudos sobre a pluriatividade na agricultura familiar brasileira.

A remarkable autosomal heteromorphism in Pseudoryzomys simplex 2n = 56; FN = 54-55 (Rodentia, Sigmodontinae)
Provedor de dados: Genetics and Molecular Biology
Autores: Moreira,Camila Nascimento; Di-Nizo,Camilla Bruno; Silva,Maria José de Jesus; Yonenaga-Yassuda,Yatiyo; Ventura,Karen.
Pseudoryzomys simplex, the false rice rat, is a monotypic genus of the Oryzomyini tribe (Sigmodontinae) distributed in part of Bolivia, Paraguay, Argentina and Brazil. Its diploid number has been described as 56 acrocentric chromosomes decreasing in size and no karyotype figure has been depicted. Herein, we present karyotypic data on P. simplex, including chromosome banding and molecular fluorescent in situ hybridization using telomeric sequences and the whole X-chromosome of its sister clade Holochilus brasiliensis (HBR) as probes. A case of remarkable autosomal heteromorphism due to the presence of a whole heterochromatic arm leading to the variability of FN is reported, as well as the occurrence of regions of homology between the X and Y chromosomes...

A Remarkable New Species of Anastrophyllum (Spruce) Steph. (Hepaticae) from Mt. Roraima, Guyana
Provedor de dados: Naturalis Digital Academic Repository
Autores: Inoue, Hiroshi; Gradstein, S. Rob.
Anastrophyllum plagiochiloides INOUE &amp; GRADST. is newly described and illustrated. This species is characterized by 1) the flat or more or less convex leaves, 2) the strongly oblique leaf-insertion line on the dorsal side, and 3) the narrowly oblong leaf-shape with a narrowly rounded or subtruncate and sometimes bidentate apex. As these characters sharply isolate the species from any other known species of Anastrophyllum, the new subgenus Vanaea INOUE &amp; GRADST. is established for this remarkable species.

We describe the new liverwort species Cheilolejeunea schiavoneana M.E.Reiner &amp;amp; Gradst. from submontane rainforest in the Western Cordillera of Colombia. The new species is related to C. adnata (C. sect. Cheilolejeunea) but differs by larger plant, leaf and underleaf size, robust stems, a 5-6 cells wide ventral merophyte, abundance of microphyllous branches, and vegetative reproduction by caducous leaf lobes produced on flagelliform shoots. The latter feature is characteristic of the genus Rectolejeunea and its presence in Cheilolejeunea is apparently a case of parallel evolution. The discovery of C. schiavoneana adds a further endemic taxon to the rich flora of the Colombian Western Cordillera.

A remarkable sand-dwelling fish assemblage from central Amazonia, with comments on the evolution of psammophily in South American freshwater fishes
Provedor de dados: Neotropical Ichthyology
Autores: Zuanon,Jansen; Bockmann,Flávio A.; Sazima,Ivan.
We studied a specialised assemblage of sand-dwelling fish species from a streamlet in central Amazonia. The five sanddwelling species comprised 15.2 % of the total number in the streamlet (33 species). Two of the sand-dwellers are daytime foragers, Characidium cf. pteroides (Crenuchidae) and Stauroglanis gouldingi (Trichomycteridae), whereas three ones are night-time foragers, Gymnorhamphichthys rondoni (Rhamphichthyidae), "Imparfinis" pristos and Mastiglanis asopos (Heptapteridae). With the exception of C. cf. pteroides, the remainder species bury in the sand during their resting period. All five species bear a cryptic, sand-colour pattern, and some are translucent, traits which we regard as advantageous both for evasion from predators and for approaching...

Nossa pesquisa parte do principio de que os produtos orgânicos são bens de qualidade diferenciada. Para se evitar o oportunismo, torna-se necessária a criação de um ambiente institucional sólido: a normatização dos parâmetros técnicos de produção e a construção de uma legislação clara. A nova legislação brasileira do setor estabeleceu que as certificadoras devem adotar os procedimentos da norma internacional ISO 65. Com isso, ABIO (Associação de Agricultores Biológicos do Estado do Rio de Janeiro), entidade que congrega a maior parte dos produtores orgânicos fluminenses, não mais conseguiria certificar seus membros a baixos preços. A manutenção da produção orgânica no estado foi ameaçada, uma vez que a maior parte dos membros da associação é de pequenos...

Autores: Janssen, Annika; Kaiser, Stefanie; Meissner, Karin; Brenke, Nils; Menot, Lenaick; Martinez Arbizu, Pedro.
Heightened interest in the exploitation of deep seafloor minerals is raising questions on the consequences for the resident fauna. Assessing species ranges and determination of processes underlying current species distributions are prerequisites to conservation planning and predicting faunal responses to changing environmental conditions. The abyssal central Pacific nodule belt, located between the Clarion and Clipperton Fracture Zones (CCZ), is an area prospected for mining of polymetallic nodules. We examined variations in genetic diversity and broad-scale connectivity of isopods and polychaetes across the CCZ.

Price expectations play a critical role in commodity markets where producers must make input decisions well before output is realized.  This paper brings together alternative expectations regimes, their estimation, and hypothesis tests for use in structural commodity models to determine their use by commodity producers.  Extrapolative mechanisms and rational expectations are considered under risk neutrality and risk aversion.  The assumptions implicit in the use of aggregate data in these models are made explicit.  Structural models using individual survey data are discussed.  While Muth's rational expectations hypothesis has found widespread acceptance in the macroeconomic literature, empirical results from industry studies indicate that commodity...

This paper presents a summary of the current knowledge on the systematics of the Greek taxa of Chorthippus, morphologically characterised by angled lateral pronotal keels (usually grouped as Glyptobothrus). Prior to this paper, based on traditional morphology, ten taxa of Chorthippus with angled lateral pronotal keels were recognized from Greece. Based on morphology as well as (and more importantly so) bioacoustics thirteen Greek taxa are now recognised. With addition of a few additional related taxa that occur only outside Greece, all are treated in this paper: Chorthippus apricarius apricarius (Linnaeus, 1758), C. vagans vagans (Eversmann, 1848) (not in Greece), C. v. cypriotus (Uvarov, 1936) stat. nov. [Cyprus], C. v. africanus Nadig, 1981 [N. Africa],...

On organic farms, where the importation of materials to build/maintain soil fertility is restricted, it is important that a balance between inputs and outputs of nutrients is achieved to ensure both short-term productivity and long-term sustainability. This paper considers different approaches to nutrient budgeting on organic farms and evaluates the sources of bias in the measurements and/or estimates of the nutrient inputs and outputs. The paper collates 88 nutrient budgets compiled at the farm scale in 9 temperate countries. All the nitrogen (N) budgets showed an N surplus (average 83.2 kg N ha-1 year-1). The efficiency of N use, defined as outputs/inputs, was highest (0.9) and lowest (0.2) in arable and beef systems respectively. The phosphorus (P) and...
