15N uptake fom manure and fertilizer sources by three consecutive crops under controlled conditions
Provedor de dados: 90
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...

Autores: Cholango, Humberto.
Los círculos políticos y académicos, todos, señalan que la malhadada alianza del Movimiento Pachakutik PK con Lucio Gutiérrez PSP, es el inicio del fin de la CONAIE, por lo tanto ahora ya no es un sujeto político activo. Todos estos intelectuales se olvidan que la realidad es más amplia que sus oficinas, para ellos la derrota del TLC por parte del movimiento indígena y otras organizaciones populares, marcó el real inicio de la descalabro del neoliberalismo, que permitiera abrir el actual periodo que estamos viviendo. También se olvidan mencionar que todos los mentalizadores y usufructuarios de la alianza PK-PSP ahora son prominentes funcionarios del gobierno. Mientras no se tomen en cuenta todos los hechos ocurridos, no podremos superar prejuicios que...

20 Jahre ‚Gäa e.V. - Vereinigung ökologischer Landbau’
Provedor de dados: 21
Autores: Wolf, Dipl.-Ing. agr. D.; Hirte, Dr. K.; Schüler, Dr. C.; Heß, Prof. Dr. J.
For the understanding of ecological agriculture, knowledge of its roots is essential.  Actual literature about this topic does not cover the history of ecological agriculture in  East Germany especially if chronological development and individual motivation are  seen as mutual dependent. The ecological organisation Gäa e.V. was founded in the  GDR in 1989. Its origins were oppositional environmental groups working within the  East German church. It developed own principles based on individual experience with  unique aspects. It has established and integrated well in the German ecological agriculture  structure after the reunification and the changed political background as an  authentic representative of and for the East German ecological agriculture scene.

2009 Michigan Land Values and Leasing Rates
Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value.

Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.; Swenson,   Andrew L.
Net farm income for all representative farms in 2018 is projected to be lower than in 2008. Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income. Commodity prices are expected to fall from current levels however the final level is unknown. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates after 2009. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit farms are expected to increase to about 0.50.

2009 Outlook of the U.S. and World Sugar Markets, 2008-2018
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2008-2018 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 remain stable over the next ten years in spite of the 2007-08 surge in world oil prices. That increase in price caused an increase in the conversion of sugar into ethanol in Brazil, while other exporting countries increased their production in response to those higher prices. Sugar prices returned to normal levels in 2008. World demand for sugar is expected to grow at a similar rate to world supply, resulting in Carribean...

This report evaluates the U.S. and world wheat markets for the 2008-2018 period 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 remain relatively healthy for the next ten years. World demand for both common and durum wheat are expected to remain strong. The price levels in 2007 and 2008 will not be maintained in 2009 and future because increased wheat and corn production in 2008 and reduced demand for corn for ethanol production will lower demand and increase supply. World trade volumes of both classes of wheat are expected to expand, but trade...

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...

30 años después : una reflexión sobre los estudios rurales y agrarios en Ecuador (Debate Agrario-Rural)
Provedor de dados: 122
Autores: Chiriboga V., Manuel.
En la primera década del siglo XXI se está produciendo un nuevo impulso a los estudios rurales y agrarios en el Ecuador. Esta revitalización tiene como protagonistas a diversos núcleos académicos situados en universidades y ONGS (sic) con marcos conceptuales y enfoques analíticos, así como especializaciones disciplinarias que los aglutinan. Algunos enfoques son sociológicos, otros provenientes de la economía política y ciencia política; economía agraria y ecología. Los  temas abordados incluyen ecosistemas y manejo de recursos naturales, tenencia de la tierra, género, trabajo rural, comercio internacional. Es evidente un nuevo dinamismo,  todavía débil, pero sin embargo prometedor. Aunque hace falta mayor interdisciplinareidad y construir espacios de...

3D model of amphioxus steroid receptor complexed with estradiol
Provedor de dados: 17
Autores: Michael E. Baker; David J. Chang.
The origins of signaling by vertebrate steroids are not fully understood.  An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates.  To investigate the evolution of estrogen binding to steroid receptors, we constructed a 3D model of amphioxus SR complexed with estradiol.  This 3D model indicates that although the SR is activated by estradiol, some interactions between estradiol and human ER[alpha] are not conserved in the SR, which can explain the low affinity of estradiol for the SR.

3D model of lamprey estrogen receptor with estradiol and 15[alpha]-hydroxy-estradiol
Provedor de dados: 17
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...

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 Bayesian approach to estimate the accuracy of "in-house" ELISA assay to measure rabies antibodies from compulsory vaccinated dogs and cattle
Provedor de dados: 80
Autores: Nogueira,AHC; Silva,C; Gomes,DE; Rosa,ACG; Luvizotto,MCR; Cardoso,TC.
Rabies is a vaccine-preventable disease that causes acute encephalitis in mammals, and it is still a significant public health problem in numerous countries. Infected dogs represent the main vectors involved in human rabies. Additionally, cattle rearing close to geographic areas where vampire bats are found presents an important connection with rural epidemiology. We applied two "in-house" enzyme-linked immunosorbent assay (ELISA) methodologies, considered alternatives to measure antibodies from vaccinated dogs and cattle, without employing the gold standard approach. The ELISA assays were performed on individual serum samples taken from domestic adult dogs and cows compulsory vaccinated against rabies (147 urban dogs and 64 cows; n = 211). The sandwich...

Mathematical models in Biology are powerful tools for the study and exploration of complex dynamics. Nevertheless, bringing theoretical results to an agreement with experimental observations involves acknowledging a great deal of uncertainty intrinsic to our theoretical representation of a real system.&amp;#xd;&amp;#xa;Proper handling of such uncertainties, is key to the successful usage of models to predict experimental or &amp;#xfb01;eld observations.

Autores: Tingting Qin; Lam Tsoi; Andrew Lawson; Jim Zheng.
We developed a Bayesian hierarchical model to identify gene networks based on the similarity score generated from comparing the gene ontology fingerprints of gene pairs. Genes in this network were assumed to have similar biological functions that can be indicated by their ontology fingerprints. Our results indicate that different pathways show consistent score threshold that allow us to distinguish biological relevant gene&amp;#x2014;gene connections in the network.

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: 5
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...

Autores: Bustabad, E. A.; Garcia, G; Rodriguez-pardo, L.; Farina, J.; Perrot, H.; Gabrielli, C.; Bucur, B.; Lazerges, M.; Rose, D.; Compere, Chantal; Arnau, A.
This work deals with the development of a high sensibility DNA biosensor based on a 50MHz Quartz Crystal Microbalance (QCM) Oscillator Electronic Circuit. The designed QCM oscillator sensor is able to detect the presence of complementary DNAs in a solution that match the sequence on a given strand in function of the changes in the output frequency of the oscillator. The design is adapted so that the Barkhausen condition is satisfied even when the quartz is immerged in liquid media. Also a comparative study of the developed 50MHz biosensor in front of a QCM oscillator with smaller frequency is carried out, with object of checking if the sensibility of the oscillator increases, allowing to detect smaller concentrations of the complementary DNA.

As the Doha negotiations are at a dead end, this paper takes a step back to address the future direction of WTO disciplines in agriculture. It puts members’ negotiating positions and the draft modalities with their ever growing list of exceptions aside to focus on three fundamental questions. First, which agricultural policy instruments should be permitted or prohibited by WTO disciplines so as to best account for the manifold effects of agriculture on societies’ welfare? Second, how should inefficient agricultural policies be treated as long as their removal is politically infeasible? And third, how can the WTO facilitate agricultural policy reform beyond establishing maximum thresholds for distorting policies? The paper argues for moving from the current...

The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. The skin wart was obtained from a cow belonging to a Brazilian beef herd. A PCR assay was carried out with the FAP primer pair, which amplifies a partial segment of the L1 gene (approximately 478 bp), and the amplicon was submitted to direct sequencing. Because nucleotide sequences with satisfactory quality scores were not obtained, the amplicon was cloned and...

Autores: Medellín-Azuara,Josué; Howitt,Richard E.; Waller-Barrera,Cynthia; Mendoza-Espinosa,Leopoldo G.; Lund,Jay R.; Taylor,Joseph E.
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...

A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals
Provedor de dados: 77
Autores: Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da.
Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.

Autores: Paull, John.
This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most  of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's...

A choice experiment method to assess vegetables producers’ preferences for crop insurance
Provedor de dados: 31
Autores: Mercade,   Lluc; Gil,   Jose Maria; Kallas,   Zein; Serra,   Jordi.
Agricultural producers face many risks in their economic activity due to weather conditions, plant or animal diseases, price volatility, policy changes and so on. One of the management tools to deal with some of these risks is the crop insurance system. In Catalonia (North-East of Spain) farmers’ participation in crop insurance for vegetables is low. Only 5 percent of the vegetables area is insured, when in Spain, as a whole, this percentage is around 20 percent. Different reasons have been suggested to explain this low participation ratio such as low risk perception, risk diversification, insurance cost or crop damage assessment rules, among others. However, no systematic research has been undertaken to assess farmers’ preferences for crop insurance in...

A cognitive psychological approach of analyzing preference uncertainty in contingent valuation
Provedor de dados: 31
Autores: Akter,   Sonia; Bennett,   Jeffrey W.
The sources of preference uncertainty in contingent valuation (CV) studies have rarely been investigated from a theoretical standpoint. This paper proposes a holistic theoretical framework of preference uncertainty that combines microeconomic theory with the theories of cognitive psychology. Empirical testing of the proposed theoretical model was carried out in Australia in the context of a national ‘Carbon Pollution Reduction Scheme (CPRS)’ to be introduced in 2010. Two separate ordered probit models for a certainty score associated with CV ‘Yes’ and ‘No’ responses were estimated. The results of the estimated regression models provide evidence supporting the hypotheses drawn from the theoretical model.

Autores: Sierra Rayne; Kaya Forest.
New experimental data is available in the literature regarding the octanol-water distribution behavior of representative straight chain perfluoroalkyl carboxylate (PFCA) and sulfonate (PFSA) congeners. The current study provides the first investigation into the predictive ability of various software programs for estimating the corresponding octanol-water partitioning (log P) and distribution (log D) constants of PFCAs and PFSAs. Wide predictive variation was found within and between the various methods. Several programs were able to accurately estimate the log P/D fragmental contributions of a -CF~2~- group for PFCAs, as well as the associated Gibbs free energies for partitioning into octanol from water due to the hydrophobic character of the...

The current study provides the first investigation into the predictive ability of various software programs for estimating the corresponding octanol-water partitioning (log P) and distribution (log D) constants of PFCAs and PFSAs. Wide predictive variation was found within and between the various methods. Several programs were able to accurately estimate the log P/D fragmental contributions of a -CF~2~- group for PFCAs, as well as the associated Gibbs free energies for partitioning into octanol from water due to the hydrophobic character of the...

A comparative efficiency analysis of wheat farms using parametric and nonparametric methods
Provedor de dados: 31
Autores: Mo,   Lijia.
This study examined whether the efficiency measures were invariant to choice of parametric and nonparametric methods for a sample of 183 wheat farms. The efficiency measures from the deterministic parametric method were smaller than those from the deterministic method. There was a trade-off between scale efficiency and economic efficiency. In the deterministic nonparametric method, the economic efficiency, scale efficiency and overall efficiency results were invariant to the number of inputs or the dimensionality. Only allocative and pure technical efficiency measures depended on the dimensionality. This work illustrated the importance of holding curvature for the cost function in stochastic frontier results.

This study assessed the micro anatomical differences in the tongue of rat, bat and pangolin with a view to establishing the functional anatomical differences of these mammalian tongues on their dietary pattern. Ten rats, ten bats and ten pangolins were used for this study. The animals were sacrificed and the tongue excised and processed for light microscopical study adopting the following stains: Haematoxylin Eosin, Verhoeff Gieson and Masson trichrome. The results showed non papillation of the keratinized stratified epithelium of pangolin tongue unlike the papillation seen in the tongue of the rat and bat. While the filiform papillation seen in the rat was bristle like, the filiform papillae in the bat were crown-like. There was also an unusual dense...

A comparative review of the fisheries resource management systems in New Zealand and in the European Union
Provedor de dados: 5
Autores: Marchal, Paul; Lallemand, Philippe; Stokes, Kevin; Thebaud, Olivier.
This review aims at comparing the fisheries management systems existing in New Zealand and in the European Union. The involvement of stakeholders at all stages of the management process is generally more transparent and better established in New Zealand than in the EU. Both systems aim at achieving an adequate balance between sustainability and utilisation and consider the precautionary approach as a founding principle. The social objectives are probably more explicit in the EU management system. In New Zealand, B-MSY is a legal management target for all stocks in the quota management system (QMS), but management strategies were poorly explicit until most recently. In the EU, there have not been any legal management targets or strategies until 1999. Since...

A Comparative Study of China's and Australia's Cotton Production
Provedor de dados: 31
Autores: Zhao,   Xufu; Tisdell,   Clement A.
After providing information about the global importance of cotton as a textile and China’s and Australia’s contribution to global cotton production, this paper examines and compares trends in the time-series of cotton production of China and Australia for the period 1980-2007. In doing so, it takes account of changes in the area planted with cotton and its yield. Correlation estimates and decomposition analysis are used to determine the relative contribution to variations in the total output of cotton of changes in the total area planted with cotton and its yield in both countries. These relative contributions are found to be quite different for Australia and China. In addition, there is a comparative analysis of fluctuations in the production of cotton,...

Autores: B. Junior,Walter; Di Chiacchio,Nilton G.; Di Chiacchio,Nilton; Romiti,Ricardo; Criado,Paulo R.; Velho,Paulo Eduardo N. Ferreira.
A study was conducted in São Paulo, Brazil, to compare azithromycin with thiamphenicol for the single-dose treatment of chancroid. In all, 54 men with chancroid were tested. The etiology was determined by clinical characterization and direct bacterioscopy with Gram staining. None of the patients had positive serology or dark-field examination indicating active infection with Treponema pallidum. Genital infections due to Neisseria gonorrhoeae and herpes simplex virus were excluded by polymerase chain reaction testing. For 54 patients with chancroid, cure rates with single-dose treatment were 73% with azithromycin and 89% with thiamphenicol. HIV seropositivity was found to be associated with treatment failure (p=0.001). The treatment failed in all HIV...

Provedor de dados: 21
Autores: Nielsen, Thorkild; Nölting, Benjamin; Kristensen, Niels Heine; Løes, Anne-Kristin.
Based on national reports from Denmark, Finland, Italy and Norway, describing the school meal systems and to which extent organic food is integrated there, this report identifies differences between the four countries and experiences made with organic food procurement and the dissemination of organic ingredients in school meals. Such knowledge will help to understand the possibilities and restrictions for increasing organic food in school meal systems, and to reveal the room of manoeuvre for public organic food procurement for youth in each country.  In the report, similarities and differences of the national school meal systems in general are first discussed, because this context determines the scope of organic food procurement.

Autores: John C. Rodda; Max A. Little; Harvey J. E. Rodda; Patrick E. McSharry.
During the 1960s, a study was made of the magnitude, frequency and distribution of intense rainfall over the UK, employing data from more than 120 daily-read rain gauges covering the period 1911 to 1960. Using the same methodology, that study was recently updated utilizing data for the period 1961 to 2006 for the same gauges, or from those nearby. This paper describes the techniques applied to ensure consistency of data and statistical modelling. It presents a comparison of patterns of extreme rainfalls for the two periods and discusses the changes that have taken place. Most noticeably, increases up to 20% have occurred in the north west of the country and in parts of East Anglia. There have also been changes in other areas, including decreases of the...

A Comparative Study of Variation of the Pterion of Human Skulls from 13th and 20th Century Anatolia
Provedor de dados: 77
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.

A Comparison between Perception of Risk and Willingness to Serve Genetically Modified Foods
Provedor de dados: 31
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.

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: 31
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.

A Comparison of Approaches to Mitigate Hypothetical Bias
Provedor de dados: 31
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....

We investigated the influence of Pinus afforestation on the structure of leaf-litter ant communities in the southeastern Brazilian Atlantic Forest, studying an old secondary forest and a nearly 30 year-old never managed Pinus elliottii reforested area. A total of 12,826 individual ants distributed among 95 species and 32 genera were obtained from 50 1 m² samples/ habitat. Of these, 60 species were recorded in the pine plantation and 82 in the area of Atlantic forest; almost 50% of the species found in the secondary forest area were also present in the pine plantation. The number of species per sample was significantly higher in the secondary forest than in the pine plantation. Forest-adapted taxa are the most responsible for ant species richness...

A comparison of three methods to estimate variations in the relative abundance of moutain vizcachas (Lagidium viscacia) in the High Andes ecosystems
Provedor de dados: 81
Autores: Lucherini,Mauro; Reppucci,Juan I.; Luengos Vidal,Estela.
Mountain vizcachas are large rodents that constitute the main prey of the High Andes meso-carnivores. We compared the line transect pellet count, observation rate and photographic rate methods to estimate the relative abundance of Mountain vizcachas in the High Andes ecosystems. Although a more formal validation based on the comparison with true abundances is desirable, our results suggested that these simple and affordable indices are promising methods, especially if protocols and sampling efforts are carefully standardized. We recommend the use of photographic rates, which are likely to provide the most reliable estimates, especially where Mountain vizcachas are active at night.

A conceptual framework for the evolutionary selection of biologically &amp;#x27;essential&amp;#x27; elements
Provedor de dados: 17
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...

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...

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: 21
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...

A contribution to the phytogeography of Brazilian campos: an analysis based on Poaceae
Provedor de dados: 88
Autores: Garcia,Ricardo José Francischetti; Longhi-Wagner,Hilda Maria; Pirani,José Rubens; Meirelles,Sérgio Tadeu.
Twenty areas from eight Brazilian states were compared according to a list of 224 species of Poaceae. In order to determinate affinity patterns between the areas, a binary matrix was submitted to cluster and ordination analysis. The patterns found were then faced to climate and geographic position. The scores corresponding to the areas obtained from the cluster analysis showed a strong correlation to temperature. The scores corresponding to the species suggest a gradient that associates distribution patterns to the photosynthetic pathway (C3 or C4). The current results suggest that the traditional classification of the Southern American grasslands might require some modification in order to be broadly applicable in the Brazilian context.

This work shows that the political and legal resources available to citrus farmers have become as strategic as financial, technological and organizational resources. The study presents an analysis of the Brazilian citrus business governance, which is defined by the use of different strategies among citrus farmers and processing plants: the citrus farmers and their main association use political resources, while some big juice processing plants resort to legal resources. This opposition represents a new obstacle to the achievement of positive results by citrus farmers in the current power network. Court orders demonstrate that orange supply contracts have become a fundamental empowering instrument in the sector, leading to strategic gains for the juice...

It was the objective of this study to take a first cut at understanding the cost structure of coastal restoration technologies and to obtain some preliminary measures of cost-effectiveness of these technologies.  This analysis focused on restoration projects funded by the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA, also known as the Breaux Act), the primary funding source for restoration projects in Louisiana.  Projects chosen were those that included a component of dredging sediment with the explicit objective of increasing acreage in the project area, i.e., of building land.

Autores: Liang,   Yan; Coble,   Keith H.
This paper employs a cost function analysis method to investigate the existence of moral hazard in cotton buy-up insurance. The trans-log cost function estimates of the own-price elasticity of fertilizer, herbicide, and insecticide is -0.222, -0.143, and -0.121, respectively for Mississippi cotton production. Our results found statistically significant relationship between per acre direct cost and cotton buy-up insurance for year 2001 and 2005 in Mississippi. Our results also indicate that moral hazard can either decrease or increase agricultural input usage depending specific production condition in an individual year.  But in general the results support effects smaller than anecdotal evidence would suggest.

Provedor de dados: 31
Autores: Hennessy,   David A.
The modeling of price risk in the theory and practice of commodity risk management has been developed far beyond that of crop yield risk. This is in large part due to the use of plausible stochastic price processes. We use the Pólya urn to identify and develop a model of the crop yield expectation stochastic process over a growing season. The process allows a role for agronomic events, such as growing degree days. The model is internally consistent in adhering to the martingale property. The limiting distribution is the beta, commonly used in yield modeling. By applying binomial tree analysis, we show how to use the framework to study hedging decisions and crop valuation.

A Cultura da goiabeira irrigada no Nordeste brasileiro.
Provedor de dados: 14
Autores: FLORI, J. E.; CASTRO, J. M. da C. e.
A cultura da goiabeira no Nordeste é explorada principalmente por pequenos agricultores. O amplo uso popular e a redução de oferta desta fruta por vários fatores, principalmente de ordem fitossanitária, vêm contribuindo para a boa rentabilidade da cultura. Outra vantagem desta cultura é o custo de produção equivalente a outras culturas, como bananeira e coqueiro, e valor da produção bem superior às mesmas. Esta relação de custo/benefício é favorável à cultura da goiabeira. Outra vantagem da cultura é a facilidade de programar sua colheita em função de expectativa de melhores preços. O Vale do São Francisco vem-se destacando cada vez mais no cenário internacional como um polo produtor e exportador de frutas frescas, com ênfase para manga e uva.

A DECOMPOSITION APPROACH TO ANALYZING RACIAL AND GENDER BIASES
Provedor de dados: 31
Autores: Wu,   Ya; Escalante,   Cesar L.; Gunter,   Lewell F.; Epperson,   James E.
This study provides a different perspective in revisiting the racial and gender discrimination issue regarding FSA loans. The Oaxaca-Blinder decomposition method, commonly used in wage discrimination analysis, is employed to determine whether there exist unwarranted differences between the loan amounts approved among racial and gender classes. The findings of this study are inconclusive. As with previous studies, no clear and convincing evidence was found to signal racial or gender discrimination with respect to approved loan amounts to farmer borrowers.

Autores: Paiva,Jacqueline Boldrin de; Penha Filho,Rafael Antonio Casarin; Arguello,Yuli Melisa Sierra; Berchieri Junior,Ângelo; Lemos,Manuel Victor Franco; Barrow,Paul A.
Salmonella enterica serovar Gallinarum (SG) is a fowl typhoid agent in chickens and is a severe disease with worldwide economic impact as its mortality may reach up to 80%. It is one of a small group of serovars that typically produces typhoid-like infections in a narrow range of host species and which therefore represents a good model for human typhoid. The survival mechanisms are not considered to be virulent mechanisms but are essential for the life of the bacterium. Mutants of Salmonella Gallinarum containing defective genes, related to cobalamin biosynthesis and which Salmonella spp. has to be produced to survive when it is in an anaerobic environment, were produced in this study. Salmonella Gallinarum is an intracellular parasite. Therefore, this...

A Drosophila systems model of withdrawal from chronic pentylenetetrazole relevant in post-epileptogenesis
Provedor de dados: 17
Autores: Priyanka Singh; Farhan Mohammad; Abhay Sharma.
Rodent kindling induced by pentylenetetrazole (PTZ) is an established model of epileptogenesis and antiepileptic drug (AED) testing. Recently, a Drosophila systems model has been described in which chronic PTZ causes a decreased climbing speed in adult males on 7th day. Some AEDs ameliorate development of this locomotor deficit. Time-series of microarray expression profiles of heads of flies treated with PTZ has been found to resemble transcriptomic alterations associated with epileptogenesis. In the fly model, withdrawal from seven day long PTZ treatment causes an increased climbing speed on 7th consequent day. Here, we present a systems model of the post-PTZ withdrawal regime. Unlike AED-untreated individuals, flies treated with any of the five AEDs...

A dual sensor device to estimate fluid flow velocity at diffuse hydrothermal vents
Provedor de dados: 5
Autores: Sarrazin, Jozee; Rodier, Philippe; Tivey, M. K.; Singh, H.; Schultz, A.; Sarradin, Pierre-marie.
Numerous attempts have been made over the last thirty years to estimate fluid flow rates at hydrothermal vents, either at the exit of black smoker chimneys or within diffuse flow areas. In this study, we combine two methods to accurately estimate fluid flow velocities at diffuse flow areas. While the first method uses a hot film anemometer that performs high-frequency measurements, the second allows a relatively rapid assessment of fluid flow velocity through video imagery and provides in situ data to calibrate the sensor. Measurements of flow velocities on hydrothermal diffuse flow areas were obtained on the Mid-Atlantic Ridge (MAR). They range from 1.1 to 4.9 mm/s at the substratum level, in low-temperature (4.5-16.4 degrees C) diffuse flow areas from...

A dynamic and mechanistic model of PCB bioaccumulation in the European hake (Merluccius merluccius)
Provedor de dados: 5
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 Characterization of Efficiency
Provedor de dados: 31
Autores: Stefanou,   Spiro E.
The definition and measurement of dynamic economic performance has been addressed obliquely in the literature with the notions of scope economies and capacity utilization measures, but little work has focused on develop the static theory analogs of efficiency measures into the dynamic context. This paper is an attempt to identify some of the conceptual and methodological issues to be addressed. A model allowing for dynamic production decisions in the face of inefficiency is presented to illustrate some of the issues and the extensions necessary to identify truly dynamic performance measures.

A emergência dos "agricultores familiares" como sujeitos de direitos na trajetória do sindicalismo rural brasileiro
Provedor de dados: 125
Autores: Lazzaretti Picolotto,Everton.
O processo de reconhecimento dos agricultores familiares como sujeitos de direitos apesar de ser recente quando pensado a partir da trajetória do sindicalismo rural brasileiro demonstra ter suas primeiras raízes ainda na constituição da legislação trabalhista-sindical dos anos de 1930. Visando explorar esse processo o artigo tem por objetivo analisar a emergência dos agricultores familiares como sujeitos de direitos na sociedade brasileira contemporânea. Analisa-se os processos de formação do sindicalismo rural e de expansão da legislação trabalhista para os trabalhadores rurais como forma de realização de uma "cidadania regulada" até a década de 1970; o questionamento do sindicalismo oficial, a estruturação de um "novo sindicalismo" e a emergência de...

A experiência norte-americana com o seguro agrícola: lições ao Brasil?
Provedor de dados: 31
Autores: Guimaraes,   Marcelo Fernandes; Nogueira,   Jorge Madeira.
Agricultural insurance is considered to be an effective to manage rural risks. Surprisingly, its adoption by farmers is very limited all over the world. An outstanding exception is the United States of America, country in which this instrument has achieved remarkable success. Nevertheless, the process of diffusion of agricultural insurance in the USA was slow and expensive. It has also required significant government intervention through a variety of complementary actions. In this context, countries willing to introduce this instrument among other agricultural policy tools, as it seems the case of Brazil, should proceed with caution. Agricultural insurance success has important pre-requisites and its general diffusion may amplify its problems. The analysis...

A experiência norte-americana com o seguro agrícola: lições ao Brasil?
Provedor de dados: 123
Autores: Guimarães,Marcelo Fernandes; Nogueira,Jorge Madeira.
O seguro agrícola é um instrumento eficaz de gestão de riscos rurais. Paradoxalmente, sua utilização pelos agricultores é relativamente reduzida em quase todo o mundo. Uma notória exceção é os Estados Unidos da América, país onde essa modalidade alcançou reconhecido sucesso. O processo, porém, foi lento, muito dispendioso e envolveu a participação determinante do Estado em diversas ações complementares. Dessa forma, países que desejam incluir esse instrumento dentre as prioridades de sua política agrícola, como parece ser o caso brasileiro, devem estar atentos aos requisitos para o seu sucesso e aos resultados e problemas gerados ou ampliados por sua massificação. O estudo da experiência norte-americana fornece lições relevantes.

A kutatás célja a fenntarthatóság lokális, helyi (kistérségi, települési) megvalósítási lehetőségeinek, megoldási módjainak, ellentmondásainak és akadályainak feltárása. A kérdőíves vizsgálat az önkormányzatoknál és a lakosságnál is ismerethiányt és gyenge kezdeményezőkészséget jelzett. Igaz, napjainkban Magyarországon a fenntarthatóságot kormányzati és helyi szinten sem kezelik jelentőségének megfelelő helyen, s a nemzeti stratégia is csak 2007-re készült el. Útmutatók és esettanulmányok híján az önkormányzatok is csak tapogatóznak, és a lakosság sincsen tisztában a nemzetközi kezdeményezés jelentőségével. A törvényi háttér csak azt rögzíti, hogy a helyi hatóságok részt vehetnek ilyen stratégiák készítésében, de nem fogalmaz meg kötelezettségeket,...

A fenntarthatóság mérése, de definiálása is nehézkes a jövőre vonatkozó feltételezések bizonytalansága miatt. Korlátozott következtetések vonhatók le pl. a „kereslet és kínálat” összehasonlításának elvén alapuló, egyre közismertebb ökológiai lábnyomból, vagy más, a fenntarthatóság bizonyos aspektusait részletesebben jellemző indikátorok tényleges értékeinek és az előre elvárt értékek összevetéséből. Ilyen, fejlődő, korlátozott lehetőségeket nyújtó indikátorrendszer jött létre az erdőgazdálkodásban. A rendszer használatát nagymértékben korlátozza, hogy megalapozatlan az, hogy hány, illetve mennyire specifikus vagy mennyire aggregált indikátorokat alkalmaznak, és hogy az indikátorok mért értékeit hogyan értelmezik. Emiatt az indikátorértékek értelmezésében...

Prevalence of bovine trypanosomosis was determined from a total of 203 blood samples collected from Butaleja district, eastern Uganda. All samples were examined by microhematocrit centrifuge test (MHC), PCR and ELISA. ELISA was performed in accordance with the OIE standard procedures using Trypanosoma brucei gambiense procyclic form crude antigens. PCR were utilized to identify the species and the subspecies of trypanosome. The overall prevalence of bovine African trypanosomosis was 8.9% by MHC, and 45.3% by the ELISA. Since substantial number (12 out of 18) of MHC positive samples were negative in the PCR tests, we could not conclude the most epidemic trypanosome species in the studied area. Nevertheless, the PCR results suggests that the most prevalent...

A financial analysis of the effect of the mix of crop and sheep enterprises on the risk profile of dryland farms in south-eastern Australia – Part 1
Provedor de dados: 31
Autores: Hutchings,   Timothy R.
This study presents a method of simulating longer-term cash flows that reflect the cumulative effects of variation in seasons, prices, enterprise sequences and mixes and other management decisions. It can be used to develop full risk profiles on a whole-farm or individual-component enterprise basis for most dryland farms in southern Australia, at gross margin, profit or cash flow levels. This analysis concentrates on the cash flow implications of these various scenarios because cash flow is the indicator which includes all costs, and therefore demonstrates affordability and the long-term viability of the farm business entity.

A first evaluation on the use of Ardea albus feathers as bioindicators of mercury burden in Amazonian ecosystems
Provedor de dados: 36
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.

A Framework for Assessing of the Impact of Capacity Building
Provedor de dados: 31
Autores: Templeton,   Deborah J.
Capacity building is widely recognised as an important component of most research-for-development activities. However despite the fact that around $15 billion is spent annually on capacity building activities, there has been limited assessment of the economic returns to that investment. In recent years, the Impact Assessment Program of the Australian Centre for International Agricultural Research has turned its attention to quantifying the benefits from capacity-building. This paper sets out a framework for assessing of the impact of capacity building and presents four case studies. It does not purport to be a definitive paper by any means. Rather, it is an account of just one organisations experience. It is hoped that as work on this important area...

A framework for the design and analysis of incentive systems for food safety control in supply chains
Provedor de dados: 31
Autores: van Wagenberg,   Coen P.A.; Backus,   Ge B.C.; van der Vorst,   Jack G.A.J.; Urlings,   Bert A.P.
Since 2005 the EU food industry has primary legal responsibility for food safety control. This requires new responsibilities and relationships between government and industry, and between companies. This research presents a framework for incentive systems for food safety control in supply chains. It emphasizes key elements of food safety control from multiple perspectives and provides insights for the design and analysis of incentive systems for food safety control. An incentive system combines inter-company incentive mechanisms with intra-company decision making processes to control a hazard within the legal environment. Incentive mechanisms, which consist of a performance measure and a performance reward, induce companies to use control measures. The...

A general-purpose method for two-group randomization tests
Provedor de dados: 31
Autores: Kaiser,   Johannes; Lacy,   Michael G.
We outline a novel approach to calculate exact p-levels for two-sample randomization tests. The approach closely resembles permute in its applications, with the main difference being that the results are approximated only if the execution time needed to calculate exact p-levels would exceed a specified maximum. We demonstrate its use by deriving p-levels for the significance of Somers’ D, the coefficient of variation, the difference in means and in medians, and the difference in two multinomials.

A glimpse on biological activities of tellurium compounds
Provedor de dados: 42
Autores: Cunha,Rodrigo L. O. R.; Gouvea,Iuri E.; Juliano,Luiz.
Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic derivatives have been studied, leading to a set of interesting and promising applications. As an example, it can be highlighted the uses of alkali-metal tellurites and tellurates in microbiology, the antioxidant effects of organotellurides and diorganoditellurides and the immunomodulatory effects of the non-toxic inorganic tellurane, named AS-101, and the plethora of its uses. Inasmuch, the nascent applications of organic telluranes (organotelluranes) as protease inhibitors and its applications in disease...

A Global Model for Agriculture and Bioenergy: Application to Biofuel and Food Security in Peru and Tanzania
Provedor de dados: 31
Autores: Elbehri,   Aziz; McDougall,   Robert; Horridge,   Mark.
This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail...

A globalizáció és a konszolidációs számvitel alkalmazása a magyar élelmiszer-gazdaságban
Provedor de dados: 31
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. Így az egyedi éves beszámolók alapján a társaságok vagyoni, pénzügyi és jövedelmi helyzetének bemutatása nem biztosítható. Az információhiány megszüntethető, ha a...

A gravity model approach to forecasting tuberculosis transmission in cattle
Provedor de dados: 31
Autores: Xie,   Fang; Horan,   Richard D.; Wolf,   Christopher A.
Bovine tuberculosis (bTB) in cattle has caused significant economic losses to livestock producers and has proven difficult to eradicate.  It is suspected that cattle movement across different farms and regions is one of the key factors of bTB transmission in the United States. Prior attempts to model the epidemiology of bTB infection within cattle to predict disease transmission have not adequately captured the behavioral aspects of trade.  A better understanding of livestock trade patterns would help in predicting disease transmission and the associated economic effects. In this paper, we develop a gravity model of livestock trade and link it to an epidemiological model of bTB transmission, with the goal being that this information could lead to improved...

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: 21
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...

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 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 produção de citros no Brasil tem sido orientada para o mercado de suco concentrado congelado, embora no Nordeste esteja dividido entre o mercado de frutas frescas e indústria de suco. A limeira ácida 'Tahiti' é uma importante variedade comercial de citros no Brasil e o limoeiro 'Cravo', seu principal porta-enxerto, apresenta suscetibilidade à gomose de Phytophthora, reduzindo a longevidade das plantas. O 'Tahiti CNPMF 2001' apresenta caneluras acentuadas de tristeza, não apresenta sintomas de descamamento eruptivo, está livre do viróide da exocorte e é considerado resistente à bactéria Xylella fastidiosa, causadora da CVC.

A Limited Information Bayesian Forecasting Model of the Cattle SubSector
Provedor de dados: 31
Autores: Abidoye,   Babatunde O.; Lawrence,   John D.
The first step towards forecasting the price and output of the cattle industry is understanding the dynamics of the livestock production process. This study follows up on the Weimar and Stillman (1990) paper by using data from 1970 to 2005 to estimate the parameters that characterizes the cattle output supply. The model is then used to estimate forecast values for the periods 2006 and 2007. Bayesian limited information likelihood method is used to estimate the parameters when endogeneity exists between these variables. The forecasting ability of the model for a two-step ahead forecast for majority of the variables are relatively good and test statistic of the forecast are reported.

A Linguistic Approach to Aligning Representations of Human Anatomy and Radiology
Provedor de dados: 17
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.

Provedor de dados: 5
Autores: Reverdin, Gilles; Gascard, Jean-claude; Le Cann, Bernard; Prieur, Loic; Assenbaum, Michel; Lherminier, Pascale.
An anticyclonic mode water vortex and its environment were investigated from November 2000 to September 2001 in the northeast Atlantic (near 43.5 degrees N, 15 degrees-19 degrees W) with neutrally buoyant drifting floats, moored current meters, satellite altimetric sea surface height, and several hydrological surveys and sections. These observations reveal a coherent inner core (similar to 0 km in diameter) made of very oxygenated northeast Atlantic central waters (11 degrees-12.7 degrees C and 35.5-35.7 on the 1978 practical salinity scale) from 150 m down to about 750-m depth. The core presents high relative vorticity (up to approximately -0.5 times the Coriolis frequency f) within at least 10 km of its center, near 400-700 m. Peak velocity along the...

Autores: FOLGUERA,GUILLERMO; BOZINOVIC,FRANCISCO.
A los 150 años de la publicación de "El origen de las especies" de Charles Darwin, numerosos homenajes se han realizado en diferentes ciudades del mundo. Sin embargo, es importante preguntarse hacia el seno de la comunidad científica acerca del alcance efectivo del darwinisimo dentro de la biología. En este trabajo analizamos este supuesto intentando responder, al menos de una manera aproximativa, la pregunta: ¿es darwinista la biología en la actualidad? A estos fines, consideramos algunos de los principales aportes que suelen asignarse al darwinismo en las ciencias de los sistemas vivos: el análisis y centro en la diversidad, un origen único de los sistemas vivos, la incorporación del azar y el reconocimiento de las causas proximales.

A low delta7 Li lower crustal component: Evidence from an alkalic intraplate volcanic series (Chaine des Puys, French Massif Central)
Provedor de dados: 5
Autores: Hamelin, Cedric; Seitz, Hans-michael; Barrat, Jean-alix; Dosso, Laure; Maury, Rene; Chaussidon, Marc.
The intraplate volcanic suite of the Chaine des Puys (French Massif Central) shows a complete petrologic range, from alkali basalts to trachytes. The significant variations of trace elements and radiogenic isotopes along the series strongly support the occurrence of crustal assimilation associated with fractional crystallization (AFC). The least contaminated basalts are clearly related to a HIMU-type reservoir (Pb-206/Pb-204&gt;19.6; Sr-87/Sr-86&lt;0.7037; epsilon(Nd)&gt;+4). The behavior of radiogenic isotopes suggests that the most likely crustal contaminants are meta-sediments located in the lower crust. The Li isotopic compositions of the lavas range from high delta Li-7 (&gt; + 7 parts per thousand) in basalts to lighter values in more evolved lavas...

A Machine Vision Algorithm Combining Adaptive Segmentation and Shape Analysis for Orange Fruit Detection
Provedor de dados: 111
Autores: M. W. Hannan; University of Florida; T. F. Burks; University of Florida; Duke M Bulanon; University of Florida.
 Over the last several years there has been a renewed interest in the automation of harvesting of fruits and vegetables. The two major challenges in the automation of harvesting are the recognition of the fruit and its detachment from the tree. This paper deals with fruit recognition and it presents the development of a machine vision algorithm for the recognition of orange fruits. The algorithm consists of segmentation, region labeling, size filtering, perimeter extraction and perimeter-based detection. In the segmentation of the fruit, the orange was enhanced by using the red chromaticity coefficient which enabled adaptive segmentation under variable outdoor illumination. The algorithm also included detection of fruits which are in clusters by using...

A magyar agrárgazdaság helyzete
Provedor de dados: 31
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 magyar agrárgazdaság versenyesélyei és stratégiai dilemmái

Autores: Udovecz,   Gabor; Popp,   Jozsef; Potori,   Norbert.
Szerzői kollektívánk az AKI 2007/7. számú tanulmányában (Alkalmazkodási kényszerben a magyar mezőgazdaság) megállapította, hogy a magyar agrárgazdaság viszonylag nagy kilengésekkel ugyan, de kényszerpályán sodródik, és kibocsátásának volumenét 2013-ig csak 6%-kal képes növelni, azt is torz szerkezetben. A behatárolt mozgástérben a mezőgazdaságból származó jövedelmek reálértéke – szintén túlzott ágazati aránytalanságokkal – legfeljebb a 2006. évi szinten marad. Rámutattunk azonban arra is, hogy ez a kedvezőtlen prognózis nem fátum, még módosítható, hiszen az adottságok alapján kínálkozik egy dinamikusabb fejlődési pálya is, amelyen a termelés volumene mintegy 25%-kal, a vállalkozói jövedelmek reálértéke pedig akár 50%-kal bővülhet. Egy évvel később az...

Autores: Nagy,   Zsuzsanna.
A szerző a magyar élelmiszer-gazdaság külkereskedelmi teljesítményét vizsgálja az EU-15 piacain a csatlakozást követően. A versenyképesség mérésére különböző modellek és mutatószámok ismertek. A hazai élelmiszer-gazdaság külkereskedelmi teljesítményét cserearány-index, koncentrációs mutató, klasszikus Grubel-Lloyd index, egyszerű RCA mutató indikátorokkal vizsgálva megállapítható, hogy a cserearány-index a 2006-2008 közötti években kedvezőbben alakult az előző három évinél. Az élelmiszer-gazdaság export- és import-koncentrációja (H-index) csökkent 2004-től, de az agrárimport továbbra is koncentráltabb; az ágazaton belüli kereskedelem szerepe (GL-index) többnyire nőtt az EU-15 piacain, azonban az értékek jelentősen szóródnak tagállamonként és...

A multinacionális láncoknál a közvetlen kisárutermelői beszállítóknak a speciális „réspiaci” termékeknél, illetve a nagy termelők között szabadon hagyott piaci réseken van mozgáslehetőségük. E termékek kivételével a közvetlen kisárutermelői beszállításoknak nincs jövője, mert elaprózott kínálattal nagy számban nem léphetnek be a beszállítói körbe.  Hatékonysági követelmények miatt előbb-utóbb a hazai láncoknál is erősödik a beszerzés koncentrációja, és ez itt is csökkenti a közvetlenül beszállító kisárutermelők ma még lényegesen nagyobb lehetőségeit. A nagy üzletláncok üzletpolitikája olyan követelményeket támaszt, amelyeket a kisárutermelők a réspiaci termékek kivételével külön-külön nem tudnak teljesíteni. Ezért közös termeltető és értékesítő...

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...

A Market Experiment on Trade Promotion Budget and Allocation
Provedor de dados: 31
Autores: Gomez,   Miguel I.; Rao,   Vithala R.; Yuan,   Hong.
We design a market experiment to examine how firm size and ability to choose trade promotion types influence trade promotion budget, its allocation and channel profits. Our experimental results show that larger manufacturers offer smaller trade promotion budgets. Manufacturers with ability to influence the allocation decision favor scan-backs while retailers favor off-invoices. Trade promotion decisions affect profit sharing within the channel but not total channel profit. We validate these findings with an econometric analysis of survey data from supermarket executives. Overall, our results suggest that market experiments can shed light on trade promotion outcomes for which industry data are sparse.

The strengthening of social organizations that made it possible for dairy production to become a market-driven activity has brought about deep changes in the sexual division of labour. The sociological analysis of the changes in family-farming intra-household roles shows that cultural traditions, gender-related power gaps, and social contexts that further deepen differences in market access between men and women are the social and cultural foundations of a hierarchy structured according to sex and generation, where women, especially the youngest, occupy greatly disadvantageous positions. With the strengthening of cooperatives, dairy production began to occupy a rather important role in providing resources to the household, yet the control over the activity...

Autores: Júlio Júnior,Horácio Ferreira; Tós,Claudenice Dei; Agostinho,Ângelo Antonio; Pavanelli,Carla Simone.
Based on long-term studies in the upper rio Paraná basin, in addition to a broad review of literature and other information, we were able to identify 33 species of native fishes in the lower rio Paraná basin that successfully colonized the upper rio Paraná after Itaipu impoundment, that flooded the natural geographic barrier constituted by the Sete Quedas Falls. These species belong to six Orders, encompassing two of Myliobatiformes, six of Characiformes, 17 of Siluriformes, six of Gymnotiformes, one of Perciformes, and one of Pleuronectiformes. Extensive remarks regarding each species, including their influence upon the native assemblage, in addition to comments on other non-indigenous species, are also provided. We conclude that, in spite of its...

A memoryless, stochastic mechanism of timing of phases of behavior by a neural network controller
Provedor de dados: 17
Autores: Saaniya Contractor; Nataliya Kozlova; Vladimir Brezina.
For a sensorimotor network to generate adaptive behavior in the environment, the phases of the behavior must be appropriately timed.  When the behavior is driven simply by the sensory stimuli from the environment, these can supply the timing.  But when the behavior is driven by an internal &amp;#x22;goal&amp;#x22; that ignores and perhaps even opposes the immediate sensory stimuli, the timing must be generated internally by the network.  We have modeled a realistic behavioral scenario that requires such internal timing.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;When the sea slug Aplysia feeds, it incrementally ingests long strips of seaweed, driven by ingestive stimuli emanating from the seaweed.

Autores: Ogundari,   Kolawole.
This study sheds light on how study specific-characteristics impact mean technical efficiency (MTE) in Nigerian agriculture.  Also the paper extracts consensus message about MTE and its drivers in Nigerian agriculture based on studies covering the period 1999-2008. A meta-analysis using truncated regression was employed on a total of sixty four studies which yield eighty six observations for the econometric analysis. The regression results show that MTE in Nigerian agriculture increased significantly over the years. Study specific-characteristics such as sample size, number of inputs used as well as studies with focus on crop and livestock production were found to significantly impact MTE. Further analyses show that studies in the Northcentral, Southwest,...

A method for reducing uncertainty in estimates of fish-school frequency response using data from multifrequency and multibeam echosounders
Provedor de dados: 5
Autores: Berger, Laurent; Poncelet, Cyrille; Trenkel, Verena.
Fish schools can be insonified simultaneously with multifrequency echosounders (e.g. Simrad EK60s) and a multibeam echosounder (e.g. Simrad ME70). This paper presents a method for combining these data to improve estimates of the relative frequency response r(f) of fish schools. Values of r(f) are now commonly used to classify echoes in fishery surveys. The data from the roll- and pitch-stabilized, high-resolution ME70 are used to correct beam-width effects in the multifrequency EK60 data. First, knowing the exact position and orientation of the transducers and the position of the vessel, the echoes are placed into a common geographic coordinate system. Then, the EK60 data are rejected if they do not include a significant percentage of the fish school...

A gazdálkodás ökonómiai kérdéseivel foglalkozók számára a piaci csere híján fontos feladat az externáliák minél szélesebb körű számszerűsítése, mivel csak a társadalom számára jelentkező összes költség és haszon figyelembevételével lehet megítélni a mindenkori agrárpolitikát. Egyre fontosabb az, hogy milyen agrárpolitikai eszközökkel oldhatók meg a liberalizált kereskedelemmel szembeni elvárások és a nem-termék jellegű javak társadalmilag optimális kibocsátása. Ebben a kettős elvárásban a földtulajdon és földhasználat szétválása előnytelen.   -------------------------------------------    In the absence of exchange in the market, researchers into economic aspects of farming place a high emphasis on quantifying externalities to the maximum extent possible....

A globális hőmérséklet-növekedés környezeti változásokhoz, a tengerszint emelkedéséhez, a csapadék mennyiségének és térbeli eloszlásának megváltozásához, szélsőséges időjárási viszonyokhoz vezet. Állat- és növényfajok kipusztulásának sebessége jelentősen nő. Bizonyos betegségek könnyebben elterjedhetnek. E fel¬sorolt hatásokból látható, hogy a mezőgazdaságot közvetlenül érinti a klímaváltozás. Fontos tehát, hogy a mezőgazdasági üzemek maguk is tegyenek a káros hatások enyhítéséért.  Lehetséges megoldás a biomassza tüzelése, amely a mezőgazdasági rendeltetésű épületek és háztartások energiaköltségeit jelentősen mérsékli.

A mezőgazdasági termelők motivációi az állati termékek előállításában
Provedor de dados: 31
Autores: Beladi,   Katalin; Kertesz,   Robert; Dudas,   Gyula.
A magyar állattenyésztés helyzete 2004 óta is folyamatosan romlik. A mezőgaz¬dasági kibocsátásból való részesedése több év óta 37-38 százalék körül stagnál, az állatállomány csökken. Mindez szorosan összefügg azzal, hogy a fontosabb ágazatok jövedelemhelyzete bizonytalan, és az évek közötti hullámzása is jelentős. A felvásárlási árak gyakran nem fedezik a termékek költségeit, és csak az állami támogatásokkal jutnak minimális nyereséghez a gazdaságok. Az átlagos értékek hátterében eltérő termelési színvonalon gazdálkodó vállalkozások húzódnak meg: versenyképesen és jövedelmezően termelők, és az eseményekkel sodródó, többnyire veszteségesen ter¬melők. Főleg ez utóbbiakkal kapcsolatban jogosan merül fel a kérdés, hogy vajon mi motiválja tevékenységüket? Az...

Autores: Farkas-Fekete,   Maria.
A tanulmány alapvető célja az, hogy hozzájáruljon az érzékenység, sérülékenység és adaptációs képesség vizsgálatának módszertanához. A kutatások eredményei felhívják a figyelmet arra, hogy bár az európai vidék összessége egyre sérülékenyebbé válik a különböző globális kihívásokra, a veszélyeztetettség mértéke régiónként eltérő. A kutatások eredményei megerősítették az IPCC 3. jelentésében megfogalmazott hipotéziseket, melyek szerint a gazdag országok ugyanolyan veszélyeztetettség mellett is kevésbé sérülékenyek, mivel nagyobb az alkalmazkodóképességük. A klímaváltozás, amely pozitív és negatív hatást is gyakorol Európa mezőgazdaságára, módosítja az eddigi komparatív előnyöket, illetve hátrányokat. Gazdasági szempontból Dél- és Közép-Kelet-Európa minden...

A mezőgazdasági vállalkozások felszámolásának kedvezőtlen káros hatásai a társadalom széles rétegeit érintik. A kutatás célja az agrárvállalkozások felszámolásához vezető okok elemzése 17 felszámolásra került mezőgazdasági gazdálkodó szervezetben, hogy a tanulságok előmozdítsák a fizetésképtelenség megelőzését és kezelését.  A vizsgált vállalkozásokban a likviditási gyorsráta, a saját tőke aránya és az eladósodottság mutatószámainak figyelemmel kísérése a fizetésképtelenség elkerülését segíthette volna. Megállapítható továbbá, hogy alacsony saját tőkével a mezőgazdasági termelés hosszú távon nem folytatható, ezért szükséges, hogy a befektetők a termelés jellegének megfelelő jegyzett tőkével alapítsanak vállalkozást, mert a hitelek felvétele nem pótolja,...

Autores: Lopes,J.B.; Moreira,J.A.; Kebreab,E.; Vitti,D.M.S.S.; Abdalla,A.L.; Crompton,L.A.; France,J.
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-based evaluation of Marine Protected Areas: the example of eastern Baltic cod (Gadus morhua callarias L.)
Provedor de dados: 5
Autores: Kraus, Gerd; Pelletier, Dominique; Dubreuil, Julien; Moellmann, Christian; Hinrichsen, Hans-harald; Bastardie, Francois; Vermard, Youen; Mahevas, Stephanie.
The eastern Baltic cod stock collapsed as a consequence of climate-driven adverse hydrographic conditions and over fishing and has remained at historically low levels. Spatio-temporal fishing closures [Marine Protected Areas (MPAs)] have been implemented since 1995, to protect and restore the spawning stock. However, no signs of recovery have been observed yet, either suggesting that MPAs are an inappropriate management measure or pointing towards suboptimal closure design. We used the spatially explicit fishery simulation model ISIS-Fish to evaluate proposed and implemented fishery closures, combining an age-structured population module with a multifleet exploitation module and a management module in a single model environment. The model is parameterized...

A model-based study of ice and freshwater transport variability along both sides of Greenland
Provedor de dados: 5
Autores: Lique, Camille; Treguier, Anne-marie; Scheinert, Markus; Penduff, Thierry.
We investigate some aspects of the variability of the Arctic freshwater content during the 1965-2002 period using the DRAKKAR eddy admitting global ocean/sea-ice model (12 km resolution in the Arctic). A comparison with recent mooring sections shows that the model realistically represents the major advective exchanges with the Arctic basin, through Bering, Fram and Davis Straits, and the Barents Sea. This allows the separate contributions of the inflows and outflows across each section to be quantified. In the model, the Arctic freshwater content variability is explained by the sea-ice flux at Fram and the combined variations of ocean freshwater inflow (at Bering) and outflow (at Fram and Davis). At all routes, except trough Fram Strait, the freshwater...

Agrifood systems need to adapt to cope with the risks and opportunities related to global changes in  climate, markets and policies. The impacts of these changes on food production, the environment and  farmer livelihoods, as well as those of changes to technology and management practices, are not  clearly understood. There is a need for improved assessment methods and tools that consider multiple  factor and scale interactions (Van Ittersum et al., 2008). In recent years, European-wide consortia,  such as SEAMLESS, have worked for creating flexible and widely applicable frameworks for  integrated assessment and and modelling of agrifood systems That work has been valuable in  developing common concepts, methods and more flexible frameworks (Ewert et al.,...

A multiple-instance scoring method to predict tissue-specific cis-regulatory motifs and regions
Provedor de dados: 17
Autores: Jin Gu.
Transcription is the central process of gene regulation. In higher eukaryotes, the transcription of a gene is usually regulated by multiple cis-regulatory regions (CRRs). In different tissues, different transcription factors bind to their cis-regulatory motifs in these CRRs to drive tissue-specific expression patterns of their target genes. By combining the genome-wide gene expression data with the genomic sequence data, we proposed multiple-instance scoring (MIS) method to predict the tissue-specific motifs and the corresponding CRRs. The method is mainly based on the assumption that only a subset of CRRs of the expressed gene should function in the studied tissue. By testing on the simulated datasets and the fly muscle dataset, MIS can identify true...

A multivariate indicator to monitor changes in spatial patterns of age-structured fish populations
Provedor de dados: 5
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: 5
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...

Provedor de dados: 16
Autores: Dance, S.P.
Since 1758, with the publication of Systema Naturae by Linnaeus, thousands of scientific names have been proposed for molluscs. The derivation and uses of many of them are here examined from various viewpoints, beginning with names based on appearance, size, vertical distribution, and location. There follow names that are amusing, inventive, ingenious, cryptic, ideal, names supposedly blasphemous, and names honouring persons and pets. Pseudo-names, difficult names and names that are long or short, over-used, or have sexual connotations are also examined. Pertinent quotations, taken from the non-scientific writings of Gertrude Stein, Lord Byron and William Shakespeare, have been incorporated for the benefit of those who may be inclined to take scientific...

Autores: Rodrigues,Cristine; Vandenberghe,Luciana Porto de Souza; Teodoro,Juliana; Oss,Juliana Fraron; Pandey,Ashok; Soccol,Carlos Ricardo.
Gibberellic acid (GA3) is an important hormone, which controls plant's growth and development. Solid State Fermentation (SSF) allows the use of agro-industrial residues reducing the production costs. The screening of strains (four of Gibberella fujikuoroi and one of Fusarium moniliforme) and substrates (citric pulp, soy bran, sugarcane bagasse, soy husk, cassava bagasse and coffee husk) and inoculum preparation study were conducted in order to evaluate the best conditions to produce GA3 by SSF. Fermentation assays were carried out in erlenmeyers flasks at 29°C, with initial moisture of 75-80%. Different medium for inoculum production were tested in relation to cells viability and GA3 production by SSF. F. moniliforme LPB 03 and citric pulp were chosen for...

A new angiosperm leaf morphotype from the Early Cretaceous (Late Aptian) of San Luis Basin, Argentina
Provedor de dados: 41
Autores: Puebla,Gabriela G.
A new fossil angiosperm leaf morphotype, "LC-Microphyll trifoliate", from the Late Aptian La Cantera Formation, central western Argentina, is described. The leaf remains occurred at the type section of the formation within a low diversity macrofloral association. Fossils are found mainly as isolated small size leaflets (0.3-1.5 cm long). The leaves are pinnately compound (imparipinnate, trifoliate), the leaflets have pinnately lobed margin, first vein category pinnate, secondary veins craspedodromous opposite to subopposite ending at the apex of lobes and an intramarginal vein. "LC-Microphyll trifoliate" is among the earliest record of leaf remains possibly allied to the eudicots and one of the first evidence of angiosperm with compound leaves.

Phenology is one of the most sensitive biological responses to climate change, and recent changes in phenology have the potential to shake up ecosystems. In some cases, it appears they already are. Thus, for ecological reasons it is critical that we improve our understanding of species&amp;#x2019; phenologies and how these phenologies are responding to recent, rapid climate change. Phenological events like flowering and bird migrations are easy to observe, culturally important, and, at a fundamental level, naturally inspire human curiosity&amp;#x2014; thus providing an excellent opportunity to engage citizen scientists.

A new assessment of the error budget of global mean sea level rate estimated by satellite altimetry over 1993-2008
Provedor de dados: 5
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...

A New Capital Regulation For Large Financial Institutions
Provedor de dados: 31
Autores: Hart,   Oliver; Zingales,   Luigi.
We design a new, implementable capital requirement for large financial institutions (LFIs) that are too big to fail. Our mechanism mimics the operation of margin accounts. To ensure that LFIs do not default on either their deposits or their derivative contracts, we require that they maintain an equity cushion sufficiently great that their own credit default swap price stays below a threshold level, and a cushion of long term bonds sufficiently large that, even if the equity is wiped out, the systemically relevant obligations are safe. If the CDS price goes above the threshold, the LFI regulator forces the LFI to issue equity until the CDS price moves back down. If this does not happen within a predetermined period of time, the regulator intervenes. We show...

We studied the reproductive system of Capparis jacobinae Moric ex Eichler (Brassicaceae), based on controlled hand-pollination and observation of pollen tube growth made in a fluorescence microscope. Of 105 self-pollinated flowers only one produced fruits (success = 0.95%), all the other flowers abscised at the same time, between the eighth and tenth day after anthesis. Nevertheless, self- and cross-pollinated pollen tubes reached the micropyle. The rate of penetrated ovules in self-pollinated flowers was lower during the first 24 h after pollination; thereafter this rate was similar between self- and cross-pollinated flowers for treatments of 48 h, 72 h and 96 h after pollination. In addition, we carried out two indirect estimates of the reproductive...

A new engineering method for understanding extrusion cooking process
Provedor de dados: 21
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 genus and two new species of mesobenthic octopuses from Australia and New Caledonia
Provedor de dados: 5
Autores: Norman, Mark D.; Boucher-rodoni, Renata; Hochberg, F. G.
Trawl surveys off Western Australia and seamounts south of New Caledonia at depths between 375 and 545 m have yielded two species of a previously unknown genus of benthic octopus (Family: Octopodidae). Histoctopus n. gen. is described here and contains two new species, Histoctopus discus and Histoctopus zipkasae n. spp. The most distinctive morphological feature of this new genus is extreme web margin development along the length of the arms, widening towards the distal tips. Of all benthic octopuses, such web margin development only occurs in this new genus and three other distinct genera, Graneledone, Pteroctopus and Velodona (from comparable depths, typically &gt;200 m). Due to significant morphological differences between these two genera and...

A new mathematical model for radiation cell killing mechanism: Target cumulating model
Provedor de dados: 17
Autores: Zhao Liang; Wu Shixiu; Xie Congyin; Zhang Li.
There are numerous mathematical or statistical models have been given out for radiation cell killing mechanism. Unfortunately, none of the model could explain the mechanism perfectly. The more advanced model for it is still necessary to be researched. Following common assumption, a new theoretical model named &amp;#x22;target cumulating&amp;#x22; model is induced from the molecular and particle physics level. The result of theoretical calculation gives the equation of cell survival rate corresponding to delivered dose and other sensitivity parameters. In addition to fit the cell survival curve well, the new model showed advantages with comparing to previous models. Also, the new model predicts or explains some phenomenon that had been observed in...

A new method to simulate the hydrological state of soil under natural conditions
Provedor de dados: 86
Autores: Wild,Anna-Katharina; Marx,Michael Thomas; Eisenbeis,Gerhard.
Micro, macro and mesofauna in the soil often respond to fluctuating environmental conditions, resulting in changes of abundance and community structure. Effects of changing soil parameters are normally determined with samples taken in the field and brought to the laboratory, i.e. where natural environmental conditions may not apply. We devised a method (STAFD - soil tubes for artificial flood and drought), which simulates the hydrological state of soil in situ using implanted cores. Control tubes were compared with treatment tubes in which floods of 15, 30, 60 and 90 days, and droughts of 60, 90 and 120 days were simulated in the field. Flooding and drought were found to reduce number of individuals in all soil faunal groups, but the response to drought...

A new mini box corer for sampling muddy bottoms in antarctic shallow waters
Provedor de dados: 52
Autores: Echeverría,Carlos Alejandro; Lavrado,Helena Passeri; Campos,Lúcia; Paiva,Paulo Cesar de.
A new Mini Box Corer (MBC-GEAMB) was developed for bottom sampling in Antarctic shallow waters down to 100 m depth from a small vessel. It consists of a detachable stainless steel box with a total sampling area of 0.0625 m², and a closing arm with a detachable blade without an external frame. MBC allowed stratified bottom sampling and good quality samples comparable to those obtained through diving. A comparison between the MBC-GEAMB and a 0.056 m²van Veen grab (VV) was undertaken for the benthic macrofaunal composition in Admiralty Bay, King George Island (Antarctica). MBC and VV samples were taken from three depths (20, 30 and 60m) in two sites. Total densities sampled with the MBC were up to 10 times higher than those obtained with van Veen grab. VV...

Carioca Lake is located within the limits of the Rio Doce State Park, in the eastern part of the state of Minas Gerais. 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 multicompartmental reaction-diffusion modeling method links transient membrane attachment of E. coli MinE to E-ring formation
Provedor de dados: 17
Autores: Satya N. V. Arjunan; Masaru Tomita.
Many important cellular processes are regulated by reaction-diffusion (RD) of molecules that takes place both in the cytoplasm and on the membrane. To model and analyze such multicompartmental processes, we developed a lattice-based Monte Carlo method, Spatiocyte that supports RD in volume and surface compartments at single molecule resolution. Stochasticity in RD and the excluded volume effect brought by intracellular molecular crowding, both of which can significantly affect RD and thus, cellular processes, are also supported. We verified the method by comparing simulation results of diffusion, irreversible and reversible reactions with the predicted analytical and best available numerical solutions. Moreover, to directly compare the localization...

A New Photobioreactor for Continuous Microalgal Production in Hatcheries Based on External-Loop Airlift and Swirling Flow
Provedor de dados: 5
Autores: Loubiere, K; Olivo, Erell; Bougaran, Gael; Pruvost, J; Robert, Rene; Legrand, J.
This study deals with the scale of a new photobioreactor for continuous microalgal production in hatcheries. The combination of the state-of-art with the constraints inherent to hatcheries has turned the design into a closed, artificially illuminated and external-loop airlift configuration based on a succession of elementary modules, each one being composed of two transparent vertical interconnected columns. The liquid circulation is ensured pneumatically (air injections) with respect to a swirling motion (tangential inlets). A single module of the whole photobioreactor was built-up to scale its geometry (diameter and length) and to optimize its design (air sparger, tangential inlets). The volumetric productivities were predicted by modeling radiative...

A new record of giant squid Architeuthis sp. (Cephalopoda: Oegopsida) in Brazilian waters
Provedor de dados: 103
Autores: Martins,Rodrigo Silvestre; Perez,José Angel Alvarez.
A carcass of a giant squid Architeuthis sp. was found afloat off Southern Brazil (28°05'S, 45°35'W) on 29 August 1999. The specimen was a mature female of 116 cm mantle length and had arms incomplete and tentacles missing. The specimen was morphologically similar to those previously described for the Southwest Atlantic, but a few peculiarities were found on the shape of the fins, head and the cross-section and length of ventral arms. Spermatophores were found embedded within the skin of the left ventral arm, at around 60 cm from the mouth, and could be traced to the core of the arm, radiating nearly four centimeters from the point of entry. This was the third record of Architeuthis in Brazilian waters and the eighth in Southwest Atlantic when the specimen...

A new snapping shrimp (Crustacea Decapoda, Alpheidae, Alpheus) from the estuarine mudflats of Kuwait
Provedor de dados: 16
Autores: Anker, A.; Grave, S. De.
A new snapping shrimp, Alpheus lutosus spec. nov., is described from the intertidal mudflats of Bubiyan Island, northern Kuwait, south of the vast Shatt-Al-Arab delta. The new species appears to be closely related to Alpheus hoplocheles Coutière, 1897 from similar estuarine habitats in China and Japan, differing mainly in the absence of a sharp distolateral tooth on the palm of the major chela, the less marked rostral carina, and the number of spines on the propodus of the third pereiopod. Both A. lutosus spec. nov. and A. hoplocheles are unique within the A. edwardsii species group in having a strong sharp distomesial tooth on the palm of the otherwise typical edwardsii-type major chela. At the type locality, A. lutosus spec. nov. is often associated with...

A new species of Albugo parasitic to Arabidopsis thaliana reveals new evolutionary patterns in white blister rusts (Albuginaceae)
Provedor de dados: 16
Autores: Thines, M.; Choi, Y.-J.; Kemen, E.; Ploch, S.; Holub, E.B.; Shin, H.-D.; Jones, J.D.G.
The obligate biotrophic lineages of the white blister rusts (Albuginales, Oomycota) are of ancient origin compared to the rather recently evolved downy mildews, and sophisticated mechanisms of biotrophy and a high degree of adaptation diversity are to be expected in these organisms. Speciation in the biotrophic Oomycetes is usually thought to be the consequence of host adaptation or geographic isolation. Here we report the presence of two distinct species of Albugo on the model plant Arabidopsis thaliana, Albugo candida and Albugo laibachii, the latter being formally described in this manuscript. Both species may occupy the same host within the same environment, but are nevertheless phylogenetically distinct, as inferred from analyses of both mitochondrial...

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.

A new species of Gymnotus (Gymnotiformes: Gymnotidae) from the Fitzcarrald Arch of southeastern Peru
Provedor de dados: 83
Autores: Maxime,Emmanuel L.; Albert,James S.
Herein Gymnotus chaviro is described from the Alto Yuruá (upper rio Juruá) of southeastern Peru, where it is locally abundant in terra firme streams and floodplain oxbow lakes, and occurs sympatrically and syntopically with the type species of the genus G. carapo. The new species is diagnosed by a unique combination of morphometric, meristic, and osteological traits, and a characteristic color pattern in which the dark band-pairs are unbranched and incompletely separated, and the pale inter-bands rarely reach to the dorsal mid-line on the anterior half of the body, being crescent-shaped in abdominal area. Gymnotus chaviro is a member of the G. carapo species group, with which it shares the presence of two pores in the dorsolateral portion of the...

A New Statistical Method for Comparative Anatomy
Provedor de dados: 77
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 sterile technique effective on capturing tramp ants for microbiological investigations
Provedor de dados: 82
Autores: Schuller,Lucia; Matté,Glavur R; Matté,Maria H.
Tramp ants are an outstanding group of organisms that have a definitive and important role in carrying pathogens. The purpose of this study was to develop a microbiological sterile technique of collecting ants from contaminated areas. The traps were composed of Petri dishes containing culture media, and were tested to verify the applicability of the system. A positive correlation between the microorganism growth and the presence of ants inside or around traps was observed. The technique described demonstrated to be useful to collect ants from different environments, helping the surveillance of pathogenic microorganisms that are of public health concern.

Provedor de dados: 16
Autores: Becking, L.E.; Lim, S.C.
In this paper we describe Suberites diversicolor spec. nov. (Porifera: Demospongiae: Hadromerida: Suberitidae) from four enclosed anchialine lakes located in Indonesia and from a confined system in Singapore. Initially this species was thought to be specific to anchialine lakes, but further comparison to coastal areas indicated that it is more widespread in inshore systems. We have used morphological characters to distinguish this species and a molecular marker to confirm that all types are the same species. Suberites diversicolor spec. nov. is encrusting or massive with small protrusions or larger globular branches. The external colour can be olive-green, blue, purple, red-orange, or orange-yellow. Suberites diversicolor spec. nov. differs from known...

A new technique for inventory of permanent plots in tropical forests: a case study from lowland dipterocarp forest in Kuala Belalong, Brunei Darussalam
Provedor de dados: 16
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...

A non-compensatory choice modeling analysis of Japanese consumers’ preferences for beef: A choice experiment approach
Provedor de dados: 31
Autores: Aizaki,   Hideo; Sawada,   Manabu; Sato,   Kazuo; Kikkawa,   Toshiko.
The purpose of this paper is to examine, using choice experiments, the Japanese consumers’ valuation of domestic Wagyu beef, domestic dairy beef, Australian beef, and US beef when considering their bovine spongiform encephalopathy (BSE) test status. Some Japanese consumers give high priority to food safety while purchasing beef; this is expected to cause a non-compensatory valuation of food safety. As compared to the results derived from a compensatory utility model, a random parameters logit (RPL) with a non-compensatory utility model provides estimation results that are fitter for the respondents’ decision-making rules and also provides more valid willingness to pay (WTP) for each type of beef. The results suggest that the RPL with the non-compensatory...

A Nonparametric Efficiency Analysis of Bean Producers from North and South Kivu
Provedor de dados: 31
Autores: Ross,   Kara L.; Dalton,   Timothy J.; Featherstone,   Allen M.
The purpose of this research is to determine how technically efficient small-scale producers are in two provinces (North and South Kivu) in the Democratic of Republic (DR) of Congo at producing two different varieties of beans: bush and climbing beans.   In addition to calculating the efficiency scores, this research attempts to identify what producer and field characteristics affect these scores.  We hypothesize that bean producers will be more productive than producers in South Kivu and that climbing bean producers will be more productive than bush bean producers.   Technical efficiency is estimated using a nonparametric approach.  A tobit model is used to examine the effect of producer and field characteristic on the efficiency score. On average, farms...

A Nonparametric Kernel Representation of the Agricultural Production Function: Implications for Economic Measures of Technology
Provedor de dados: 31
Autores: Livanis,   Grigorios T.; Salois,   Matthew J.; Moss,   Charles B.
The issue of production function estimation has received recent attention, particularly in agricultural economics with the advent of precision farming. Yet, the evidence to date is far from unanimous on the proper form of the production function. This paper reexamines the use of the primal production function framework using nonparametric regression techniques.  Specifically, the paper demonstrates how a nonparametric regression based on a kernel density estimator can be used to estimate a production function using data on corn production from Illinois and Indiana. Nonparametric results are compared to common parametric specifications using the Nadaraya-Watson kernel regression estimator. The parametric and nonparametric forms are also compared in terms of...

A Novel Adoption Index of Selected Agricultural Technologies: Linkages with Infrastructure and Productivity
Provedor de dados: 31
Autores: Jain,   Rajni; Arora,   Alka; Raju,   S.S.
Variations in agricultural productivity in different states across the country are mainly due to large differences in the level of adoption of selected agricultural technologies and the underlying determinants of adoption of these technologies. Agricultural technologies selected in this paper include high-yielding varieties of seeds, chemical fertilizers, pesticides, use of machinery, etc. The pattern of adoption has been examined across the country based on the 54th round of NSSO dataset. The quantification of adoption has been carried out for each state in the form of a novel ‘adoption index’. The relation between adoption index and status of the infrastructure in the corresponding state has been examined. The strong correlation between adoption index...

A novel _Drosophila_ post-genomic CNS drug discovery model detects tetraethylammonium chloride with therapeutic potential
Provedor de dados: 17
Autores: Priyanka Singh; Farhan Mohammad*; Abhay Sharma.
A _Drosophila_ behavioral and transcriptomic model of locomotor plasticity induced by chronic pentylenetetrazole (PTZ) has recently been developed. In this model, two of the five antiepileptic drugs (AEDs) tested, sodium valproate (NaVP) and levetiracetam (LEV), not ethosuximide (ETH), gabapentin (GBP) and vigabatrin (VGB), ameliorate development of chronic PTZ induced locomotor alteration. Transcriptomic effect of the AEDs and PTZ in fly head has been described. Here, we analyze microarray expression profile of heads of flies treated with the convulsants tetraethylammonium chloride (TEA) and pilocarpine hydrochloride (PILO). Strikingly, microarray clustering placed TEA, not PILO, with LEV and NaVP in one group that was distinct from the other one...

In a newly described _Drosophila_ model, two of the five antiepileptic drugs (AEDs) tested, sodium valproate (NaVP) and levetiracetam (LEV), not ethosuximide (ETH), gabapentin (GBP) and vigabatrin (VGB), ameliorate development of chronic pentylenetetrazole (PTZ) induced locomotor alteration. To further characterize the model, we analyze here the microarray expression profile of heads of flies treated with depolarizing compound potassium chloride (KCl). Surprisingly, microarray clustering showed unexpected similarity among KCl, LEV and NaVP. Further, like the two effective AEDs in the fly model, KCl regulated genes overrepresented ribosomal pathway. Interestingly, KCl also ameliorated development of locomotor deficit in the chronic PTZ model. Both...

A novel missense mutation p.L76P in the GJB2 gene causing nonsyndromic recessive deafness in a Brazilian family
Provedor de dados: 56
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...

A novel polar-based human face recognition computational model
Provedor de dados: 56
Autores: Zana,Y.; Mena-Chalco,J.P.; Cesar Jr.,R.M.
Motivated by a recently proposed biologically inspired face recognition approach, we investigated the relation between human behavior and a computational model based on Fourier-Bessel (FB) spatial patterns. We measured human recognition performance of FB filtered face images using an 8-alternative forced-choice method. Test stimuli were generated by converting the images from the spatial to the FB domain, filtering the resulting coefficients with a band-pass filter, and finally taking the inverse FB transformation of the filtered coefficients. The performance of the computational models was tested using a simulation of the psychophysical experiment. In the FB model, face images were first filtered by simulated V1- type neurons and later analyzed globally...

Autores: Nicholas A. Williamson; Charles Reilly; Chor-Teck Tan; Sri-Harsha Ramarathinam; Alun Jones; Christie L. Hunter; Francis R. Rooney; Anthony W. Purcell.
The detection and quantitation of exogenously administered biological macromolecules (e.g. vaccines, peptide and protein therapeutics) and their metabolites is frequently complicated by the presence of a complex endogenous mixture of closely related compounds. We describe a method that incorporates stable isotope labeling of the compound of interest allowing the selective screening of the intact molecule and all metabolites using a modified precursor ion scan. This method involves monitoring the low molecular weight fragment ions produced during MS/MS that distinguish isotopically labelled material from related endogenous compounds. All isotopically labelled substances can be selected using this scanning technique for further analysis whilst other...

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 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: 5
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 Paradox for Agro-Environmental Land Policy
Provedor de dados: 31
Autores: Hennessy,   David A.; Feng,   Hongli.
A regulator with a fixed budget to spend on securing environmental benefits from farmed land has to choose between how many acres to enroll and the extent of benefits to require of each enrolled acre. Here we consider, given heterogeneous land, what properties of the environmental benefit-to-cost ratio imply for the choice of optimal program as the available budget varies. Conditions are found such that a program of high benefits on few acres is preferred for any budget level. It is also possible that a program delivering low benefits per acre at low cost is preferred on each land type, and yet a high benefit program is optimal policy, a variant of Simpson’s paradox.

A partial analysis of the fruit and vegetable sector in Austria
Provedor de dados: 31
Autores: Hambrusch,   Josef; Quendler,   Erika.
With respect to the new Common Market Organisation (CMO) for fruit and vegetables, the present paper focuses on societal developments that influence the demand for fruits and vegetables, provides some basic information on fruit and vegetable production in Austria and, finally, describes the roles of Producer Organisations (PO) and retailers in Austria. The study is based on a literature review as well as on interviews with representatives of the POs. The results reveal that six Austrian POs face an increasing concentration process in the Austrian retail industry, which is important since roughly 90% of all fruits and vegetables are distributed in retail and discount outlets. Furthermore, during the last ten years the overall consumption of fruits and...

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...

Provedor de dados: 101
Autores: Pérez,L.J.; Díaz de Arce,Heidy; Barrera,Maritza; Castell,Sara; Frías,María T.
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 porcine gene, PBK, differentially expressed in the longissimus muscle from Meishan and Large White pig
Provedor de dados: 74
Autores: Yonggang,Liu; Sumei,Zhao; Hongbin,Pan; Shizheng,Gao.
An investigation of differences in gene expression in the longissimus muscle of Meishan and Large White pigs was undertaken, using the mRNA display technique. A fragment of one differentially expressed gene was isolated and sequenced, whereupon the complete cDNA sequence was then obtained by using the rapid amplification of cDNA ends (RACE). The nucleotide sequence of the gene is not related to any known porcine gene. Sequence analysis revealed that the open reading frame of this gene encodes a protein with 322 amino acids, thus displaying high sequence identity with the PDZ binding kinase (PBK) of eleven other animal species - dog, horse, cattle, human, chimpanzee, crab-eating macaque, rhesus monkey, rat, mouse, gray short-tailed opossum and platypus, so...

A Practical Algorithm for Multiple-Phase Control Systems in Agricultural and Natural Resource Economics
Provedor de dados: 31
Autores: Doole,   Graeme J.
Many important problems in agricultural and natural resource economics concern an intertemporal choice between alternate dynamic systems. This significance has motivated a theoretical literature generalizing the necessary conditions of Optimal Control Theory to multiple-phase problems. However, gaining detailed insight into their practical management is difficult because general numerical solution methods are not available. This paper resolves this deficiency through the development of a flexible and efficient computational algorithm based on a set of necessary conditions derived for finite-time, multiple-phase systems. Its effectiveness is demonstrated in an application to a nontrivial crop rotation problem.

A precíziós gazdálkodás – 90-es évek közepétől kezdődő – alkalmazását követően napjainkban is megválaszolásra vár a beruházás megtérülési idejének és a területnagyságnak az összefüggése. Megállapítható, hogy a beruházás az eszközök gyors avulását figyelembe véve, 3 éves megtérülés esetén, 3 millió Ft (áfával együtt) értékű eszközberuházás, 21 140 Ft/ha inputfelhasználás és 5%-os megtakarítási szint mellett 946 ha-on térülhet meg az inputanyag-megtakarításból. Természetesen több végeredmény is lehetséges a változók függvényében.  --------------------------------------  Ever since precision farming was introduced in the mid-nineties, correlations between payback period and area size have been unexplored.

Autores: Sinka,   Anett.
A hagyományos mezőgazdasági termelés negatív hatásainak kiküszöbölése ér¬dekében az Európai Unió országaiban az utóbbi évtizedben egyre fontosabbá vált a multifunkcionális mezőgazdaság. Ahhoz, hogy a vidékfejlesztés, a környezetgazdálkodás az agrárgazdaság integrált részévé váljék, a gazdasági gyakorlatnak szá¬mos területen szükséges változtatni: merőben új módszerek alkalmazása, a koráb¬ban használt vagy meglévő technológiák megújítása, mások által már kipróbált eljá¬rások adaptálása, mind-mind egy-egy lehetőséget kínál a jól működő, többfunkciós mezőgazdasághoz. Mindezen okok mérlegelése után döntött úgy az Agárdi Farm Kft., hogy átáll a ha¬gyományos gazdálkodásról a precíziós növénytermelésre. A precíziós növényterme¬lési technológia nem más, mint a...

A predictive distribution model for Andinomys edax (Rodentia: Cricetidae) in Argentina
Provedor de dados: 81
Autores: Jayat,Pablo; Pacheco,Silvia; Ortiz,E.
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...

Autores: Moreira,Lorena A.; Fenolio,Danté B.; Silva,Hélder Lúcio Rodrigues; Silva Jr,Nelson Jorge da.
Termite mounds are known to offer refuge and microhabitats to a great variety of invertebrates and vertebrates. In the valley of the upper Tocantins River, within areas of influence of hydroelectric power plants 4,000 termite mounds were surveyed to evaluate the diversity of amphibians and reptiles using these environments. Surveys in termite mounds from two other areas (Corumbá River and Araguaia River basins) were used for comparative purposes. The results for termitaria in the upper Tocantins river valley revealed nine families, 13 genera, and 25 species of amphibians, and 16 families, 32 genera, and 47 species of squamate reptiles. Compared to a general herpetofaunal list of the region, the data indicate that between 30.6% and 56.8% of the species use...

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.

We document an increasing prevalence of the term ―collective entrepreneurship‖ in scholarly research. By examining the context in which the term is utilized, we present a framework through which to understand motivations for research in collective entrepreneurship and the variety of entrepreneurial endeavors described as collective entrepreneurship. We identify five primary motivations for research: advancement of theory, intra-organizational efficiency, inter-organizational gains, economic growth and development, and socio-political change. We find preliminary evidence collective entrepreneurs may be able to generate rents inaccessible to the sole entrepreneur. In addition, we propose mechanisms which foster entrepreneurship may differ for sole and...

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 Profile of the Western Cape Province: Demographics, Poverty, Income, Inequality, and Unemployment from 2000 till 2007
Provedor de dados: 31
Autores: Jacobs,   Elne; Punt,   Cecilia.
The Western Cape agricultural sector is a dynamic and livelihood sustainable sector. Approximately 3.9% of the Western Cape value added gross domestic product comes through agriculture and 3% of the population in the Western Cape is working in this sector. There is thus a need for macro-economic research in order to investigate potential and current challenges and opportunities.  This paper examines several of these challenges namely demographic compositions, unemployment, income distribution, poverty and inequality. It will provide results from the Labour Force Surveys from 2000 until 2007 with a more in-depth look into 2007. Population and labour force statistics provide the foundation for further analysis. This paper indicates that unemployment is being...

A Quality Evaluation Framework for Bio-Ontologies
Provedor de dados: 17
Autores: Jesualdo Tomas Fernandez-Breis; Mikel  Ega&amp;#xf1;a Aranguren; Robert Stevens.
Over the past few years the number of bio-ontologies  has rapidly increased. The evaluation of ontologies has long been a problematic issue. The growing number of ontologies makes the need for a strategy for evaluating quality more urgent. We propose a framework for evaluating the quality of bio-ontologies. This framework is inspired by a well-known software quality standard, which has been adapted to the needs of ontology evaluation. An example of how to use the framework, comparing two versions of the Open Biomedical Ontologies&amp;#x27; Cell Type Ontology, is included as an illustration.

A quantitative estimation of the energetic cost of brown ring disease in the Manila clam using Dynamic Energy Budget theory
Provedor de dados: 5
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 randomised controlled trial of an intervention to promote early presentation of breast cancer in older women: effect on breast cancer awareness
Provedor de dados: 17
Autores: Louise Linsell; Lindsay  J. L. Forbes; Marcia  Kapari; Caroline  Burgess; Lynne  Omar; Lorraine  Tucker; Amanda J. Ramirez.
There is virtually no evidence for the effectiveness of interventions to promote early presentation in breast cancer. We tested the efficacy of an intervention to equip older women with the knowledge, skills, confidence and motivation to detect symptoms and seek help promptly, with the aim of promoting early presentation with breast cancer symptoms. We randomised 867 women aged 67 to 70 attending for their final routine appointment on the UK NHS Breast Screening Programme to receive: a scripted ten-minute interaction with a radiographer plus a booklet; a booklet alone; or usual care. The primary outcome was whether or not a woman was breast cancer aware based on knowledge of breast cancer symptoms and age-related risk; and reported breast checking. At one...

A Reaction Route Approach to Flux Balance Analysis
Provedor de dados: 17
Autores: Ilie  Fishtik.
Background: Flux balance and network-based pathway analyses are theoretical tools aimed to find optimal steady state flux distributions in a metabolic network subject to additional constraints on the rates of the reaction steps. Although these methods are mathematically accurate, there are several physicochemical and computational aspects that are questionable and misleading. In particular, it is well known that the flux balance analysis may result in multiple flux distributions for the same objective function.  &amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Results: The flux balance and network-based pathway analyses are reformulated in terms of reaction routes (RRs), a theoretical framework that has been developed by Horiuti over 50 years ago. Not only does the...

A redescription of Astyanax gymnodontus (Eigenmann, 1911), new combination, a polymorphic characid fish from the rio Iguaçu basin, Brazil
Provedor de dados: 83
Autores: Pavanelli,Carla Simone; Oliveira,Carlos Alexandre Miranda.
Astyanax gymnodontus (Eigenmann, 1911), new combination, a polymorphic characid fish endemic to the Rio Iguaçu basin in Southern Brazil, is redescribed. The species was originally described as belonging to the monotypic genus Psalidodon, distinguished from Astyanax by the possession of a single series of teeth on the premaxilla (vs. two series), by the presence of relatively compressed teeth on the premaxillary and dentary bones (vs. relatively bulky teeth), and by the absence of lips (vs. lips present). Examination of a large number of specimens from the rio Iguaçu basin that present dental and lip features that were intermediate between Psalidodon and Astyanax indicated that specimens attributed to Psalidodon show extreme characters observed within a...

A retrospective analysis of the effects of adopting individual transferable quotas in the Tasmanian red rock lobster, Jasus edwardsii, fishery
Provedor de dados: 5
Autores: Hamon, Katell; Thebaud, Olivier; Frusher, Stewart; Little, L. Richard.
Individual transferable quotas (ITQ) were implemented in the Tasmanian red rock lobster fishery in 1998 and ten years later we assessed the impacts on the fishery. Particular attention was devoted to investigating the performances of the fishery with regard to three features identified as major impacts in the literature: rationalization of the fishing fleet, change in fishing strategy in order to maximise the fisher's profit and concentration of fishing rights and activity. On average, the fishery reacted as expected and reached its objective in terms of reconstruction of the biomass, but the overall assessment in terms of resulting profitability is not very conclusive. There is no evidence of decrease of the profitability over the period of the study but...

Autores: Ommati,L.V.M.; Rodrigues,C.A.; Silva,A.R.; Silva,L.P.; Chaufaille,M.L.L.F.; Oliveira,J.S.R.
Allogeneic hematopoietic stem cell transplantation (AHSCT) is the treatment of choice for young patients with severe aplastic anemia (SAA). The association of antithymocyte globulin (ATG) and cyclophosphamide (CY) is the most frequently used conditioning regimen for this disease. We performed this retrospective study in order to compare the outcomes of HLA-matched sibling donor AHSCT in 41 patients with SAA receiving cyclophosphamide plus ATG (ATG-CY, N = 17) or cyclophosphamide plus busulfan (BU-CY, N = 24). The substitution of BU for ATG was motivated by the high cost of ATG. There were no differences in the clinical features between the two groups, including age, gender, cytomegalovirus status, ABO match, interval between diagnosis and transplant, and...

A review of Chorthippus species with angled pronotal lateral keels from Greece with special reference to transitional populations between some Peloponnesean taxa (Orthoptera, Acrididae)
Provedor de dados: 16
Autores: Willemse, F.; Helversen, O. von; Odé, B.
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.

A review of fishery-independent assessment models, and initial evaluation based on simulated data
Provedor de dados: 5
Autores: Mesnil, Benoit; Cotter, John; Fryer, Rob J.; Needle, Coby L.; Trenkel, Verena.
Large uncertainties in catch data (officially-reported landings and discards) are undermining the ability of scientific organisations to provide valid management advice based on the conventional approach of analytical stock assessments. There is thus an urgent need to consider alternative tools that do not depend on long series of precise age-structured catch data. This paper presents four fishery-independent assessment models developed under the EU project FISBOAT (Fishery Independent Survey Based Operational Assessment Tools). It also reports on rudimentary tests based on simulated data, using the same data sets and protocol as an evaluation study conducted by the US National Research Council in 1997. The survey-based assessment models at hand are able...

Autores: Kaye-Blake,   William; Li,   Frank Y.; Martin,   A. McLeish; McDermott,   Alan; Neil,   Hayley; Rains,   Scott.
Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in New Zealand agriculture. One part of the paper focuses on options for modelling land and other resources such as water, labour and capital in this model, as well as markets for exchanging resources and commodities. A second part considers options for modelling agent heterogeneity, especially risk preferences of farmers, and the impacts on decision-making. The final section outlines the MAS that the authors will be constructing over the next few years and the types of...

A review of techniques for spatial modeling in geographical, conservation and landscape genetics
Provedor de dados: 74
Autores: Diniz-Filho,José Alexandre Felizola; Nabout,João Carlos; Telles,Mariana Pires de Campos; Soares,Thannya Nascimento; Rangel,Thiago Fernando L.V.B.
Most evolutionary processes occur in a spatial context and several spatial analysis techniques have been employed in an exploratory context. However, the existence of autocorrelation can also perturb significance tests when data is analyzed using standard correlation and regression techniques on modeling genetic data as a function of explanatory variables. In this case, more complex models incorporating the effects of autocorrelation must be used. Here we review those models and compared their relative performances in a simple simulation, in which spatial patterns in allele frequencies were generated by a balance between random variation within populations and spatially-structured gene flow. Notwithstanding the somewhat idiosyncratic behavior of the...

A review of the role of submarine canyons in deep-ocean exchange with the shelf
Provedor de dados: 5
Autores: Allen, S. E.; Durrieu De Madron, X.
Cross shelf-break exchange is limited by the tendency of geostrophic flow to follow bathymetric contours, not cross them. However, small scale topography, such as canyons, can reduce the local lengthscale of the flow and increase the local Rossby number. These higher Rossby numbers mean the flow is no longer purely geostrophic and significant cross-isobath flow can occur. This cross-isobath flow includes both upwelling and downwelling due to wind-driven shelf currents and the strong cascading flows of dense shelf-water into the ocean. Tidal currents usually run primarily parallel to the shelf-break topography. Canyons cut across these flows and thus are often regions of generation of strong baroclinic tides and internal waves. Canyons can also focus...

Over the past decade, &amp;#8220;Payments for Environmental Services&amp;#8221; (PES) have received a great deal of attention as a natural-resource management approach. We propose a revised definition and framework for PES implementation that focuses on the use of positive incentives as the philosophy behind PES and conditionality as the method for influencing behaviors. We note the importance of additionality of PES interventions to justify their value in a wider context. Finally, we highlight the need to understand the local institutional context in terms of the characteristics of buyers, sellers, and their relationship for implementation to be effective. Our framework acts as a platform to begin examining how the variety of options for structuring PES...

In the first paper of this series (Albuquerque &amp;amp; Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii group species and revise the other Oxyepoecus species-group (Rastratus). We describe two species (Oxyepoecus myops n. sp. and O. rosai n. sp.) and redescribe previously known species of the group [O. daguerrei (Santschi, 1933), O. mandibularis (Emery, 1913), O. plaumanni Kempf, 1974, O. rastratus Mayr, 1887, and O. reticulatus Kempf, 1974], adding locality records and comments on the meagre biological data of these species. We also present an identification key to Oxyepoecus species based on workers.

A robust, multisite Holocene history of drift ice off northern Iceland: implications for North Atlantic climate
Provedor de dados: 5
Autores: Andrews, John T.; Darby, Dennis; Eberle, Dennis; Jennings, Anne E.; Moros, Matthias; Ogilvie, Astrid.
An important indicator of Holocene climate change is provided by evidence for variations in the extent of drift ice. A proxy for drift ice in Iceland waters is provided by the presence of quartz. Quantitative x-ray diffraction analysis of the &lt; 2 mm sediment fraction was undertaken on 16 cores from around Iceland. The quartz weight (wt.)% estimates from each core were integrated into 250-yr intervals between -0.05 and 11.7 cal. ka BP. Median quartz wt.% varied between 0.2 and 3.4 and maximum values ranged between 2.8 and 11.8 wt.%. High values were attained in the early Holocene and minimum values were reached 6 7 cal. ka BP. Quartz wt.% then rose steadily during the late Holocene. Our data exhibit no correlation with counts on haematite-stained quartz...

A RT-PCR assay for the detection of encephalomycarditis virus infections in pigs
Provedor de dados: 58
Autores: Pérez,Lester J.; Díaz de Arce,Heidy.
Encephalomyocarditis virus (EMCV) infections can cause losses in pig farms all over the world. Rapid, sensitive and unequivocal detection of this virus is therefore essential for the diagnosis and control of the disease. An RT-PCR assay was developed, optimized and evaluated for encephalomyocarditis virus detection in organ based on a pair of primers that amplifies a 165 bp DNA fragment from a highly conserved nucleotide region of the viral 3D glycoprotein. PCR products of the expected size were obtained from Cuban EMCV 744/03 strain. Non-specific reactions were not observed when other porcine RNA genome viruses and uninfected cells were used. The analytical sensitivity of the test was estimated to be 2 TCID50/50 mL. The analysis of tissue homogenate...

A Safety Valve for Emissions Trading
Provedor de dados: 31
Autores: Stranlund,   John K.
This paper considers the optimal design of an emissions trading program that includes a safety valve tax that allows pollution sources to escape the emissions cap imposed by the aggregate supply of emissions permits. I demonstrate that an optimal hybrid emissions trading/emissions tax policy involves a permit supply that is strictly less than under a pure emissions trading scheme and a safety valve tax that exceeds the optimal pure emissions tax as long as expected marginal damage is an increasing function. While the expected level of emissions under a hybrid policy may be more or less than under pure emissions trading or a pure emissions tax, under the assumption that uncertainty about aggregate marginal abatement costs is symmetric the most likely...

A Scientific Review of the Impact of UK Ruminant Livestock on Greenhouse Gas Emissions
Provedor de dados: 31
Autores: Hopkins,   Alan; Lobley,   Matt.
Climate change is a subject of global environmental concern. The UK has seen a progressive strengthening of political resolve to address the problems associated with emissions of greenhouse gases (GHGs), principally carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Although agriculture globally, and ruminant livestock production in particular, is a net contributor to GHG emissions, generalizations about impacts on climate change often fail to distinguish between different systems of production, advances in technology, and the role of extensive grazing lands in contributing to ecological services and food production in situations where other forms of farming are impractical. Against this background, the overall aim of this review was therefore to...

A Search Model for Joint Implementation
Provedor de dados: 31
Autores: Bella,   Giovanni.
The aim of this paper is to present a search model in the field of environmental economics, where so-called clean and dirty producers enter the trading market, both looking for a partner with whom to exchange the goods they are endowed with. The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights, and is conveniently used here as a framework to explain the functioning of Joint Implementation programmes for polluting emissions’ reduction.

A semi-quantitative assay to screen for angiogenic compounds and compounds with angiogenic potential using the EA.hy926 endothelial cell line
Provedor de dados: 48
Autores: ARANDA,EVELYN; OWEN,GARETH I.
Angiogenesis, the development of new capillary vessels, has a host of clinical manifestations. The identification of agents that increase or decrease angiogenesis is of great pharmaceutical interest. Classically, in vitro angiogenesis utilizes human umbilical vein endothelial cells (HUVEC) grown in matrigel. This valid and simple method has the drawbacks that each cell population is distinct and the constraint of obtaining primary source material. Herein we utilize the established EA.hy926 endothelial cell line as our model for in vitro angiogenesis and present a novel formula to quantify endothelial cell remodeling to identify pro- and anti-angiogenic agents. Furthermore, our technique details the procedures to identify and quantify compounds that have...

A sequential approach for improving AZODYN crop model under conventional and low-input conditions
Provedor de dados: 21
Autores: David, Christophe; Jeuffroy, Marie-Hélène.
Advances in scientific understanding of the plant and soil behaviour in a cultivated field led to the design of numerous soil-crop models simulating crop growth. The frequent low predictive quality of these models is linked to uncertainties in inputs, parameters and equations. The AZODYN crop model predicting wheat grain yield and grain protein content was previously developed to support decision for N management of conventional and organic wheat crops. This paper outlines a sequential approach to improve the predictions of the AZODYN model by testing various formalisms. This study is based on the comparison of 38 versions of the model assessed in multi-environment trials carried out under conventional or low-input conditions. This paper describes and...

Autores: Pantelis Topalis; Emmanuel Dialynas; Elvira Mitraka; Elena Deliyanni; Inga Siden-Kiamos; Christos Louis.
We are developing a set of ontologies that deal with vector-borne diseases and the arthropod vectors that transmit them. For practical reasons (application priorities), we initiated this project with an ontology of insecticide resistance followed by a series of ontologies that describe malaria as well as physiological processes of mosquitoes that are relevant to, and involved in, disease transmission. These will be expanded to encompass other vector-borne diseases as well as non-mosquito vectors. The aim of the whole undertaking, which is worked out in the frame of the international IDO (Infectious Disease Ontology) project, is to provide the community with a set of ontological tools that can be used both in the development of specific databases and, most...

Autores: Cesar,Augusto; Abessa,Denis Moledo de Souza; Pereira,Camilo Dias Seabra; Santos,Aldo Ramos; Fernández,Nuria; Choueri,Rodrigo Brasil; DelValls,Tomas Angel.
In this work, multivariate and numeric methods were used to integrate the chemical and ecotoxicological data obtained for the sediments from the Santos Estuarine System, and for the vicinity of the discharges of the Submarine Sewage Outfall of Santos, in order to establish more accurately the environmental risks, identify the priority areas and thus provide guidance to control the programs and public policies. For both the datasets, the concentrations which exceeded numeric sediment guidelines tended to be associated to toxicity. For the estuary, this trend was corroborated by the correlations between the toxicity and Cu and PAHs levels, whereas for the sewage outfall region, this was observed through the correlation between the toxicity and Hg contents....

A simple clustering of the BioModels database using semanticSBML
Provedor de dados: 17
Autores: Falko Krause; Wolfram Liebermeister.
The BioModels database contains biochemical network models in SBML format, in which the biochemical meaning of elements is specified by MIRIAM-compliant RDF annotations. We used these annotations to define a similarity measure for models, scoring the overlap of the biochemical systems described. Based on this score, we used two-way clustering to detect groups of similar models and groups of co-occuring model elements. To recognize and compare biochemical elements, we used routines from the software semanticSBML. A Python script extracts all MIRIAM annotations (regardless of their qualifiers) using the semanticSBML annotation classes. The result is a matrix in which the rows represent the models (e.g. BioModel 001), while the columns represent specific...

A simple model for circadian timing by mammals
Provedor de dados: 56
Autores: Cardoso,F.R.G.; de O. Cruz,F.A.; Silva,D.; Cortez,C.M.
Circadian timing is structured in such a way as to receive information from the external and internal environments, and its function is the timing organization of the physiological and behavioral processes in a circadian pattern. In mammals, the circadian timing system consists of a group of structures, which includes the suprachiasmatic nucleus (SCN), the intergeniculate leaflet and the pineal gland. Neuron groups working as a biological pacemaker are found in the SCN, forming a biological master clock. We present here a simple model for the circadian timing system of mammals, which is able to reproduce two fundamental characteristics of biological rhythms: the endogenous generation of pulses and synchronization with the light-dark cycle. In this model,...

A simplified model for A. Niger FS3 growth during phytase formation in solid State fermentation
Provedor de dados: 52
Autores: Spier,Michele Rigon; Letti,Luiz Alberto Junior; Woiciechowski,Adenise Lorenci; Soccol,Carlos Ricardo.
A simplified model to describe fungal growth during citric pulp fermentation for phytase production was described for the first time. Experimental data for biomass growth were adjusted to classical mathematical growth models (Monod and Logistic). The Monod model predictions showed good agreement with the experimental results for biomass concentration during 96 hours of fermentation. Parameters such as yield of biomass from oxygen (Y X/O), maintenance coefficient (m) and specific growth rate (µ) were compared showing a good correlation between the data and the model. An alternative method for biomass determination in this process was developed since a great correlation was found between biomass growth and enzyme formation.

Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Thomsen, Mette Hedegaard; Thomsen, Anne Belinda; Schmidt, Jens Ejbye.
In order to evaluate new strategies for the production of  renewable energy within sustainable organic agriculture, a process-simulation model for a 100 ha organic farm was developed. Data used for the model was obtained from laboratory trials, literature data, consultancy with experts, and results from the BioConcens project (http://www.bioconcens.elr.dk). Different design approaches were evaluated in order to establish the most suitable configuration. Rye grains, clover grass silage, maize silage, whey and cattle manure were selected as raw materials for co-production of fuels, feed and fertilizer at the organic farm, based on the fact that crops grown in organic agriculture act as key carbon sources whereas manure and whey were applied primarily as the...

A six-rhabdomere, open rhabdom arrangement in the eye of the chrysanthemum beetle Phytoecia rufiventris: some ecophysiological predictions based on eye anatomy
Provedor de dados: 47
Autores: Meyer-Rochow,Victor Benno; Mishra,Monalisa.
We are describing a rhabdom organization of the eye of the chrysanthemum beetle Phytoecia rufiventris that to date has not been described from any other insect. In cerambycid beetles free rhabdomeres, forming a circular, open rhabdom, surround a central rhabdom made up of the rhabdomeres of one or two cells. In Phytoecia rufiventris the central rhabdomeres are missing throughout the eye and the microvilli of the outer 6 rhabdomeres are regularly oriented in three directions. Following the classification of rhabdom types suggested by Wachmann (1979), we suggest to name the rhabdom arrangement seen in the retina of Phytoecia rufiventris "Grundmuster 3". This pattern ought to facilitate polarization sensitivity and movement perception, features that agree...

A Spatial Analysis of Conservation Reserve Program Participants: The Impact of Absenteeism on Participation Decisions
Provedor de dados: 31
Autores: Brady,   Michael P.; Nickerson,   Cynthia J.
Given that approximately half of all U.S. farmland is leased, absentee (non-operator) landowners have a significant role in agriculture. Because decisions about how to use farmland can be affected by ownership status, tenure can have far reaching implications for the production of food and fiber, as well as the extent to which environmentally sensitive farmland is cropped or is put into a conservation use.  In order to better understand whether conservation participation decisions, and potential responses to factors such as commodity prices, may vary by tenure status, we exploit a unique dataset that identifies where participants associated with Conservation Reserve Program contracts live relative to the land enrolled. These data provide improved spatial...

A spatial bio-economic modelling approach on the trade-offs between global bioenergy demand, agricultural intensification, expansion, and trade
Provedor de dados: 31
Autores: Lotze-Campen,   Hermann; Popp,   Alexander; Beringer,   Tim; Muller,   Christoph; Lucht,   Wolfgang.
Increased future demands for food, fibre and fuels from biomass can only be met if the available land and water resources on a global scale are used and managed as efficiently as possible. The main routes for making the global agricultural system more productive are through intensification and technological change on currently used agricultural land, land expansion into currently non-agricultural areas, and international trade in agricultural commodities and processed goods. In order to analyse the trade-offs and synergies between these options, we present a global bio-economic modelling approach with a special focus on spatially explicit land and water constraints as well as technological change in agricultural production. For a given bioenergy demand...

Spatial regression models incorporating non-stationarity in the regression coefficients are popular. We propose a spatial variant of the Smooth Transition AutoRegressive (STAR) model that is more parsimonious than commonly used approaches and endogenously determines the extent of spatial parameter variation. Uncomplicated estimation and inference procedures are demonstrated using a neoclassical convergence model for United States counties.

A Speculative Bubble in Commodity Futures Prices? Cross-Sectional Evidence
Provedor de dados: 31
Autores: Sanders,   Dwight R.; Irwin,   Scott H.; Merrin,   Robert P.
Recent accusations against speculators in general and long-only commodity index funds in particular, include: increasing market volatility, distorting historical price relationships, and fueling a rapid increase and decrease in commodity inflation. Some researchers have argued that these market participants—through their impact on market prices—may inadvertently prevented the efficient distribution of food aid to deserving groups. Certainly, this result—if substantiated— would counter the classical argument that speculators make prices more efficient and thus improve the economic efficiency of the agricultural and food marketing system. Given the very important policy implications, it is crucial to develop a more thorough understanding of long-only index...

Fungi are abundant in the biosphere. They have fascinated mankind as far as written history goes and have considerably influenced our culture. In biotechnology, cell biology, genetics, and life sciences in general fungi constitute relevant model organisms. Once the phylogenetic relationships of fungi are stably resolved individual results from fungal research can be combined into a holistic picture of biology. However, and despite recent progress, the backbone of the fungal phylogeny is not yet fully resolved. Especially the early evolutionary history of fungi and the order or below-order relationships within the ascomycetes remain uncertain. Here we present the first phylogenomic study for a eukaryotic kingdom that merges all publicly available fungal...

A straightforward multiallelic significance test for the Hardy-Weinberg equilibrium law
Provedor de dados: 74
Autores: Lauretto,Marcelo S.; Nakano,Fabio; Faria Jr,Silvio R.; Pereira,Carlos A.B.; Stern,Julio M.
Much forensic inference based upon DNA evidence is made assuming Hardy-Weinberg Equilibrium (HWE) for the genetic loci being used. Several statistical tests to detect and measure deviation from HWE have been devised, and their limitations become more obvious when testing for deviation within multiallelic DNA loci. The most popular methods-Chi-square and Likelihood-ratio tests-are based on asymptotic results and cannot guarantee a good performance in the presence of low frequency genotypes. Since the parameter space dimension increases at a quadratic rate on the number of alleles, some authors suggest applying sequential methods, where the multiallelic case is reformulated as a sequence of "biallelic" tests. However, in this approach it is not obvious how...

A Structural Analysis of Contractual Innovations within the CIS Milk Industry
Provedor de dados: 31
Autores: Jackson,   Elizabeth; Gorton,   Matthew; White,   John.
Utilising primary survey data, this paper evaluates the relationships between a set of supplier development strategies and performance within the milk industry in Armenia and Ukraine. Improving supplier performance is a critical task for the dairy industry in the Former Soviet Union as, during the 1990s both the quantity and quality of agricultural output deteriorated sharply. Fragmented supply chains led to high transaction costs and, in some cases, market failure. Drawing on the work of Krause et al. (2000) and Doney and Cannon (1997), a theoretical framework is presented that proposes that, either directly or indirectly, supplier assessment strategies, supplier incentives, competitive pressure, direct involvement, and trust between buyers and sellers,...

A Structural Equation Model of the Factors Influencing British Consumers’ Behaviour towards Animal Welfare
Provedor de dados: 31
Autores: Toma,   Luiza; McVittie,   Alistair; Hubbard,   Carmen; Stott,   Alistair W.
Results of national and pan-European consumer surveys and the growth in the demand for so-called “animal friendly” food products suggest that consumers within the European Union show a high level of concern for the welfare of farm animals. This paper analyses the determinants of British consumers’ behaviour towards animal welfare using structural equation models (SEM) with observed and latent variables. SEM is a statistical technique for testing and estimating relationships amongst variables, using a combination of statistical data and qualitative causal assumptions. We used a data set collected in 2005 through face-to-face interviews of 654 consumers in England. We analysed the range of statements in existing literature on consumers’ behaviour towards...

This case study on the former Rice Growers Association (RGA) analyzes the effects of a variety of business decisions and market changes, relative to the ongoing Farmers’ Rice Cooperative (FRC). Interview and survey findings reveal that many respondents felt RGA’s Board of Directors was passive and, despite its large size, lacked the necessary expertise to direct management and represent the best interest of the broader cooperative membership. In the midst of challenging market conditions, RGA’s management teams were accused of making a number of poor business decisions that led to significant financial stress and the eventual dissolution of the firm.

We evaluated the performance of the ELISA technique in the detection of IgA antibodies against different Mycobacterium tuberculosis antigenic preparations in serum samples from 49 patients with pulmonary tuberculosis collected before and after the start of specific treatment. The controls consisted of serum samples from healthy patients without any prior contact with the bacteria and serum samples from patients with other pneumopathies. Glycolipid antigen gave the best diagnostic performance, with a sensitivity of 88% and specificities varying from 88 to 100% in the control groups. These antigens constitute a powerful tool for the diagnosis and monitoring of patients with pulmonary tuberculosis.

In the present work, the effect of bed expansion on BSA adsorption on Amberlite IRA 410 ion-exchange resin was studied. The hydrodynamic behavior of an expanded bed adsorption column on effects of the biomolecules and salt addition and temperature were studied to optimize the conditions for BSA recovery on ion-exchange resin. Residence time distribution showed that HEPT, axial dispersion and the Pecletl number increased with temperature and bed height, bed voidage and linear velocity. The binding capacity of the resin increased with bed height. The Amberlite IRA 410 ion-exchange showed an affinity for BSA with a recovery yield of 78.36 % of total protein.

This paper contributes empirical evidence to the on-going debate on short sales. Our examination of how market-wide short-sale restrictions affect aggregate market returns focuses on two main questions: What is the effect of short-sale restrictions on skewness, volatility, the probability of market crashes, and liquidity? What is the effect on the market expected return or cost of capital? We report new data on the history of short-selling and put option trading regulations and practices from 111 countries, and create a short-selling feasibility indicator for the analysis of stock market indices around the world. We find that when short-selling is possible, aggregate stock returns are less volatile and there is greater liquidity. When countries start to...

The viability of agricultural enterprises is of paramount importance. Their liquidation has harmful effects on broad strata of society. The aim of my research is therefore to analyze the leading causes of liquidation of agricultural enterprises. The research was led on 17 agricultural enterprises. This may help in the prevention and treatment of their insolvency. The research results show that a long-term agricultural production is not sustainable with a low equity capital. For the long-term maintenance it is necessary that the investors establish the enterprise with a capital according to the type of the production. The loan can not replace the entrepreneurs own resources, it is only complementary to it. The owners of agricultural businesses should strive...

Using Rotterdam demand system this study examines the demand relationships among four random-weight (FW) and fixed-weight citrus (RW). Results indicated that FW and RW grapefruit (and FW and RW oranges) are not substitutes; however, RW tangerine is a substitute of FW tangerines. In addition, promoting FW grapefruit would not influence the demand for RW grapefruit and vice versa. Promoting FW oranges (or FW tangerines) would decrease the demand for RW oranges (or RW tangerines) and vice versa.

A study of the distribution of phylogenetically conserved blocks within clusters of mammalian homeobox genes
Provedor de dados: 74
Autores: Stojanovic,Nikola.
Genome sequencing efforts of the last decade have produced a large amount of data, which has enabled whole-genome comparative analyses in order to locate potentially functional elements and study the overall patterns of phylogenetic conservation. In this paper we present a statistically based method for the characterization of these patterns in mammalian DNA sequences. We have applied this approach to the study of exceptionally well conserved homeobox gene clusters (Hox), based on an alignment of six species, and we have constructed a map of Hox cataloguing the conserved fragments, along with their locations in relation to the genes and other landmarks, sometimes showing unexpected layouts.

Tropicana introduced a new package design as part of its advertising and branding campaign, with the theme “Squeeze it’s a Natural in January 2009.  Sales of the Tropicana Pure Premium line plummeted 20% between the January and February from the same period a year ago.  Tropicana had changed its mind and went back to the earlier packaging at the end of February.  This study examined the impact of Tropicana’s package redesign on the sales of Tropicana orange juice and on the sales of all orange juice.  Study results show that the package redesign cost Tropicana an estimated $27 million.

A Study of the Mechanism of Action of Zervamicin IIB Peptide Antibiotic by Molecular Dynamics Simulation
Provedor de dados: 17
Autores: Konstantin Shaitan; Olga V. Levtsova; Vladimir Makarov; Mikhail P. Kirpichnikov.
We model mechanism of action of a channel-forming peptide antibiotic, zervamicin IIB, by molecular dynamics (MD) simulation. Interaction of this peptide with neutral and negatively charged lipid bilayers is investigated. It is found that charge of membrane surface influences the orientation of zervamicin IIB molecule, that may in turn effect its permeation into the membrane. On this basis we propose modifications to ZrvIIB structure that may increase its affinity towards the prokaryotic cellular membrane. Zervamicin IIB transmembrane channels are modeled as bundles consisting of 4, 5 and 6 individual peptide monomers. Our results suggest that four monomers don&amp;#x2019;t form a stable water-filled ion channel. Thus the channel with the least number of...

A study of tourist’ attitudes and preferences for local products in Crete and changes induced by the current economic crisis
Provedor de dados: 31
Autores: Proust,   Remi; Angelakis,   George; Drakos,   Periklis.
The Cretan tourism sector has been characterised by a large and rapid growth from 1970 to 2000 and has gone on the primary industry of the island. Despite the fact that this growth has seemed stagnant over the last few years, tourism is still of vital importance for the local economy. Agricultural industries are strongly linked with tourism activities and usually derive numerous benefits from them. Understanding tourists’ opinions and demands plays a crucial role in implementing appropriate and sustainable future agricultural offer strategies on the island in the future. As several studies have previously indicated, the current global economic and financial crisis has deeply cut household expenditure and 2009 has been predicted to be a difficult year for...

A Study on the Extent of Adoption of Various Recommended Technologies in Wheat Cultivation in Punjab
Provedor de dados: 31
Autores: Singh,   Mandeep; Chahal,   S.S.
The extent of adoption of various recommended production technologies and returns from wheat crop in Punjab have been studied for the years 2006-07, 2007-08 and 2008-09. The results reveal that the area under recommended varieties of wheat has decreased from 95.29 per cent in 2006-07 to 90.63 per cent in 2008-09. At the same time, it has been observed that a majority of the sample farmers grow wheat at recommended time by using recommended quantity of seed per acre. Although the percentage of farmers who treat the seed before sowing wheat crop has increased from 27.81 per cent in 2006-07 to 39.00 per cent in 2008-09, still a majority of the farmers do not follow this technology. It has been advocated by the PAU that zero tillage of wheat can save up to Rs...

A Supply-Chain Analysis of Food Safety Standards Related to the Use of Wastewater for Irrigation of Crops
Provedor de dados: 31
Autores: Lagerkvist,   Carl Johan; Johansson,   Helena; Birol,   Ekin; Roy,   Devesh; Narrod,   Clare A.
Irrigation with raw or diluted wastewater is a widespread phenomenon, occurring on 20 million hectares across the developing world, especially in Asian countries, but also in peri-urban areas around almost every city of sub-Saharan Africa and in many Latin American cities. Growing urban populations and consequent increases in demand for food and water has spurred the use of sewage to water crops as this is, in many cases, the only form of irrigation for farmers who either lack clean water or for whom clean water is too expensive. Wastewater has high nutrient value and constitutes a reliable source (Scott et al., 2004). It is mostly used to produce cash crops (e.g. vegetables and cereals). For example, it has been estimated that in most parts of Sub-...

Autores: Abreu,Heber S.; Latorraca,João V.F.; Pereira,Regina P.W.; Monteiro,Maria Beatriz O.; Abreu,Fábio A.; Amparado,Kelysson F.
In spite of the great importance of cellulose the lignin is considered the second most abundant substance of the wood. However, little attention has been given it, mainly to wood properties. The lignin as well as other structural compounds (cellulose and hemicelluloses), has obviously an important role on the wood properties, probably due its composition and existent bonds. In general lignins have β-O-4 (Alkyl Aril Ether) as majoritary bond. This bond in a continued structure form big molecules with spiral conformation as virtual model. Based on this idea, lignins that have high/low β-O-4 content may have differentiated spiraled structures,suggesting different behaviors on the wood properties,which shows that the lignins (Guaicyl:Syringyl (GS)) of...

Autores: Manouselis,   Nikos; Konstantas,   A.; Palavitsinis,   N.; Costopoulou,   Constantina; Sideridis,   Alexander B.
The role that information technology plays in today’s business activities has led to an  increase in firms using and/or deploying e-markets online. This development undoubtedly affects the agri-food sector, since a large number of agricultural firms are demonstrating or are expected to demonstrate e-commerce activities. This paper aims to provide an overview of the current status of agricultural e-markets in Greece, by presenting results from an analysis of 100 cases. Results indicate that Greek e-markets may  still have a rather low degree of sophistication, but they demonstrate a strong B2B orientation, as well as an outreach for international customer bases.

Despite the prevalence of syphilis worldwide, little is known about its manifestations when associated with other Sexually Transmitted Infections (STI), specifically the Human Papilloma Virus (HPV). Current epidemiological studies show that there is a high incidence of both diseases in ambulatory clinics all over Brazil. This study aims to estimate the incidence of syphilis - HPV co-infections, among patients from the STI ambulatory clinic at the Santa Casa da Misericórdia Hospital, Rio de Janeiro, Brazil. Two-hundred and seven patients were seen in the clinic between March and December 2005, of which 113 (54.6%) sought care for an HPV infection. Blood samples were taken from all patients to check syphilis serology using the flocculation and the...

Magyarországon is teret hódít a biomassza villamos energia termelésére történő felhasználása. A tanulmány Magyarországon képződő szőlővenyige és fanyesedék biomassza-erőművi beszállításának lehetőségeivel foglalkozik. 2009-ben már öt hazai nagyerőműben tüzelnek a környező erdőgazdaságokból származó alapanyagot. Magyarországon rendkívül sok az energetikai célra hasznosítható szőlővenyige és fanyesedék, ami nem kerül hasznosításra, holott ezek erőművi beszállítása – számításaink alapján – 45 km-es szállítási távolság alatt már gazdaságos lehet. A tanulmány hangsúlyozza, hogy az említett melléktermékek erőművi eltüzelése – csekély jövedelemtermelő képessége miatt – jövedelemszerzés helyett inkább a „felesleges” melléktermékektől való megszabadulást, az...

A támogatások szerepe a magyar mezőgazdaságban
Provedor de dados: 31
Autores: Kovacs,   Gabor.
Az agrár- és vidékfejlesztési támogatások a világ számos országában igen jelentősek. Magyarországon a 2008-ban kifizetett támogatások a szektor által előállított bruttó hozzáadott érték közel 44 százalékát tették ki. Ezt a juttatást – egyfajta közvetett adóként – a fogyasztók, illetve a többi ágazat finanszírozza (jórészt az EU szintjén). Ezért folyamatosan célszerű vizsgálni, hogy az agrártámogatások által okozott torzulások (pl. a termelés fennmaradása versenyképtelen üzemekben, a termelési struktúra nemkívánatos változásai) kellően indokolhatók-e ökonómiai vagy más előnyökkel, illetve hogy ezek a célok hatékonyabb módon is elérhetők-e? Hazánkban a támogatások az elmúlt öt év átlagában elérték a gazdaságok adózás előtti eredményének másfélszeresét...

Autores: Lencses,   Eniko.
A Szent István Egyetem Józsefmajori tangazdaságának relatív jó talajadottságokkal rendelkező tábláiban a precíziós tápanyagpótlás alkalmazásával akár hektáronként 60 kg nitrogénhatóanyag-megtakarítás is elvárható a konvencionális technológiához képest. A precíziós tápanyagpótlási technológiával, a vizsgált táblák 50%-ánál tapasztalható anyagköltség-megtakarítás. Az anyagmegtakarítás mellett célszerű számolni a működési költségek növekedésével. A Szegedi Gabonakutató Kft. segítségével végzett szántóföldi kísérletek adatai alapján megállapítható, hogy kukoricatermelésnél 48,85% őszi gyomborítottság felett ökonómiailag indokolt a precíziós gyomirtás.   -----------------------------------   By applying precision nutrient supplementation rather instead of...

A mezőgazdasági termelést meghatározó tényezők – környezeti, gazdasági, tár¬sadalmi és politikai szempontból – jelentősen változtak az elmúlt öt évtizedben. Földrajzi elemzésünk eredményeként látható, hogy napjainkban átmeneti időszakban vagyunk, melyet jól definiálható trendek, a mezőgazdasági területek csökkenése és az élelmiszerek iránti kereslet növekedése határoznak meg, ezért hazánkban fontos feladat, hogy e körülmények között a KAP 2014 utáni reformjára felkészüljenek. Fontos, hogy olyan támogatási rendszer érvényesüljön, amely a környezetre ható és a területhasználatban jelentkező negatív folyamatokat új pályára állítja, vagyis fenntartható legyen.

A Theory of Migration as a Response to Occupational Stigma
Provedor de dados: 31
Autores: Stark,   Oded; Fan,   C. Simon.
Drawing on the literature of occupational status and social distance, a theory is developed of labor migration that is prompted by a desire to avoid “social humiliation.” A closed-economy general equilibrium model that incorporates occupational status and examines the interaction between the goods market and the labor market is constructed. This framework is then extended from a closed, single economy to an open economy setting in a world that consists of two countries or two regions. It is shown that as long as migration can reduce humiliation sufficiently, migration will occur even between two identical economies. Hence, a new model of migration is presented in which migration arises from a wish to reap social exposure gains. The model shows that...

Autores: Swinnen,   Johan F.M.; Rozelle,   Scott; Xiang,   Tao; Vandemoortele,   Thijs.
Consumers have increasing demands for product standards. This has important implications for development. This paper develops a formal theory of the process of the introduction of high product standards in developing countries. The model endogenizes the introduction of high standards. Initial differences in income, the nature of capital constraints and transaction costs, the initial production structure and policies and institutions are shown to affect the likelihood of and the size of the high standards economy. Initial differences in some of these same factors—as well as inter-country differences in the distribution of the sizes of farmers—are also shown to determine which producers are included, and which not.

Abnormal self-renewal and differentiation are defining features of acute myeloid leukemia (AML).  Using models of hematopoiesis, we show that persistent self-renewal that ignores differentiation signals can be produced through two distinct pathways.  One pathway prevents repression of stem cell genes, producing daughter cells that resemble parental stem cells despite differentiation inducing lineage-specifying factor or cytokines.  Runx1 deficiency, a frequent abnormality in AML, demonstrates the second pathway, which allows cytokine/lineage-specifying factor mediated repression of stem cell genes but impairs subsequent activation of differentiation genes that terminate transit-amplification, producing self-renewal in daughter cells that do not resemble...

Autores: Gusmão,Isabel C. P.; Moraes,Peterson B.; Bidoia,Ederio D.
A thin layer electrochemical cell was tested and developed for disinfection treatment of water artificially contaminated with Staphylococcus aureus. Electrolysis was performed with a low-voltage DC power source applying current densities of 75 mA cm-2(3 A) or 25 mA cm-2 (1 A). A dimensionally stable anode (DSA) of titanium coated with an oxide layer of 70%TiO2 plus 30%RuO2 (w/w) and a 3 mm from a stainless-steel 304 cathode was used in the thin layer cell. The experiments were carried out using a bacteria suspension containing 0.08 M sodium sulphate with chloridefree to determine the bacterial inactivation efficacy of the thin layer cell without the generation of chlorine. The chlorine can promote the formation of trihalomethanes (THM) that are...

A turizmus szerepe a Mátravidéken

Autores: David,   Lorant; Toth,   Geza.
A Mátra településeinek jó része társadalmi-gazdasági problémákkal küzd, melyeket jól jellemez az elvándorlás, a magas munkanélküliség, alacsony vállalkozássűrűség, illetve jövedelem. Az Észak-magyarországi Régióban végzett kutatásainkban már korábban megállapítottuk ezeket a tényeket. A Mátravidék fejlődésének egyik alapja lehetne az idegenforgalom/turizmus, de megállapítható, hogy kereskedelmi szálláshely-ellátottság tekintetében lakosságarányosan jelentősen elmarad a vidéki átlagtól, tehát fejlesztésekre van szükség. Véleményünk szerint elsősorban a meglévő 3 és 4 csillagos szállodák minőségi fejlesztését szükséges végrehajtani. Ha a Mátravidék turizmusa dinamikus fejlődésnek indul, a minőségi szálláshelyek férőhely-kapacitásának növelése is indokolt...

A two-stage productivity analysis using bootstrapped Malmquist index and quantile regression
Provedor de dados: 31
Autores: Kaditi,   Eleni A.; Nitsi,   Elisavet I.
This paper examines the effects of farm characteristics and government policies in enhancing productivity growth for a sample of Greek farms, using a two-stage procedure. In the 1st-stage, non-parametric estimates of Malmquist index and its decompositions are computed, while a bootstrapping procedure is applied to provide their statistical precision. In the 2nd-stage, the productivity growth estimates are regressed on various covariates using a bootstrapped quantile regression approach. The effect that the covariates exert on productivity growth of the average producer is analyzed, as well as the marginal effect of a given covariate for individuals at different points in the conditional productivity distribution. The results indicate that there exists...

A Two-Step Auction in the Presence of Negative Values: An Application to “Farm-Raised” Pre-Cooked Roast Beef
Provedor de dados: 31
Autores: Nalley,   Lawton Lanier; Hudson,   Darren.
Uniform auctions are commonly used to elicit willingness to pay for new or novel products, product attributes, or non-market goods. However, most auctions or other contingent-valuation techniques do not allow for negative values, despite the fact that many consumers hold negative values for these products or product attributes. We conducted a WTP auction for a new product along with a within-sample WTA second auction allowing for negative responses. We find that failing to allow for negative values significantly inflates willingness to pay estimates and estimates of expected market share. This paper provides a method of incorporating negative values into auctions and willingness to pay elicitation.

A Typical Scene: Five Exposures to Poverty
Provedor de dados: 31
Autores: Kanbur,   Ravi.
Over the past decade, I have been involved with an “Exposure and Dialogue Program” (EDP), which literally exposes analysts and policy makers to the lived reality of poor women’s lives by getting them to spend a few days experiencing that life. After each EDP, participants are encouraged to write up their experiences in the form of “personal” and “technical” notes. This compendium brings together the personal notes I did for my five exposures.

A Typology of Food Security in Developing Countries under High Food Prices
Provedor de dados: 31
Autores: Yu,   Bingxin; You,   Liangzhi; Fan,   Shenggen.
The recent surge in food prices around the world may reverse the gains of reducing hunger and poverty in the recent years. This paper employs factor and sequential typology analysis using data for 175 countries to identify groups of countries categorized according to four measures of food security: utilization, availability, accessibility and stability. Nine indicators are used for this study: calories intake, protein intake, fat intake, food production, the ratio of total exports to food imports, soil fertility, length of growing period, coefficient of variation of length of growing period and urbanization. The analysis first identifies 5 distinct food security groups characterized by food intake then further split these groups based on similarities and...

A tőkeszerkezet és a jövedelmezőség kapcsolata mezőgazdasági vállalkozásokban

Autores: Herczeg,   Adrienn.
A versenyképes termelés, a jövedelmező gazdálkodás érdekében a megfelelő tőkeszerkezet, a tevékenység számára „optimális” tőkestruktúra kialakítása elengedhetetlen része a pénzügyi vezetők feladatainak, amit a vállalatok értékmaximalizálása során számításba kell venniük. A vizsgált jövedelmezőségi mutatók regressziós analízise révén igazolódott, hogy a forrásszerkezeti arányok jelentősen hatnak a jövedelmezőségre. Meghatározásra került továbbá egy olyan tőkeáttételi arány – tevékenységi irány és méretspecifi kusan –, melyről elmondható, hogy az azt meghaladó érték veszteséges gazdálkodással párosul. Megállapítható, hogy az optimális tőkestruktúra megteremtése érdekében első lépésben a saját források szerepének erősítésére szükséges törekedni, mindenekelőtt...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains
Provedor de dados: 17
Autores: Claudiu I. Bandea.
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology. This article presents a broad, unifying scenario on the origin and evolution of cellular and viral domains that challenges the conventional views about the history of life and supports a TOL that includes viruses. Co-evolution of viruses and their host cells has led to some of the most remarkable developments and transitions in the evolution of life, including the origin of non-coding DNA as a genomic protective device against viral insertion damage. However, one of the major fundamental evolutionary...

A utilização de mapas temáticos no diagnóstico de áreas suscetíveis à contaminação por percolado de aterro sanitário
Provedor de dados: 70
Autores: Rowe,Elmo J.; Cardoso,Décio L.
Atualmente, a preocupação com a proteção de áreas destinadas ao abastecimento público é eminente, pois a disponibilidade de água é cada vez menor. Entre as prováveis fontes de poluição das águas estão os aterros sanitários mal operados, aterros controlados e lixões. Os processos de contaminação no solo ocorrem lentamente e, frequentemente, sem consequências imediatas, porém, em longo prazo, podem ter efeitos sérios e possivelmente irreversíveis. O diagnóstico e a visualização da possível pluma de contaminação, em áreas destinadas à disposição de resíduos, podem ser realizados pela utilização de softwares que utilizam técnicas de interpolação, que transformam dados X, Y, Z, criando mapas temáticos. Com esse objetivo, foram coletadas amostras de solo a 1 e 2...

A value chain and cluster perspective on competitiveness of European fresh vegetable production – Case studies from Germany, Italy, and Spain
Provedor de dados: 31
Autores: Riedel,   Bettina.
In the present study we combine cluster theory with a value chain approach, with the aim of discovering elements of the European fresh vegetable business that could enable local producers to gain competitive advantages in a global market.  European producers of fresh vegetables are under pressure to improve their performance and increase their competitiveness. Competitive advantage can be gained through innovation and by using unique resources stemming from cooperation between producers and complementary actors in local clusters. However, locally clustered producers do not sell to open markets but need access to value chains governed by lead firms, the large European retail chains, which set the rules and conditions of participation.  The study presents...

The examination of competitiveness – thanks to its many definitions and the applied research methods – is a complex task, and this is especially true in the case of agricultural products. The competitiveness of Hungarian agricultural product has to this day been examined by several foreign and Hungarian experts and the results of their examinations have been made public. At the same time very little special literature deals with the different explanations and interpretations of the concept of competitiveness, and the analysis of the suitability of the measurement methods. In my essay I attempt to show the locatable definitions of competitiveness, and to show without aiming for completeness, the measurement methods which are deemed acceptable in special...

A vision of the future of the Common Agricultural Policy
Provedor de dados: 31
Autores: Elkes,   Andrea; Halmai,   Peter; Papp,   Gergely; Udovecz,   Gabor; Vasary,   Viktoria.
The reforms proposed by the authors intend to ensure the economic, social and environmental sustainability of rural regions and place agricultural policy on a fundamentally different basis. The scope of community and state intervention will change. Payments linked to production will be cancelled and the provision of public goods will be rewarded instead. At the same time, measures aimed at enhancing the viability of the rural economy and society will become more significant. The depth of the changes calls for a new name expressing better the new approach, so instead of CAP the use of a more justified name is suggested: Common Agricultural and Rural Policy (CARP). This paper outlines the vision and the major proposals we suggest to meet the above mentioned...

Autores: Knight,   Brad; Malcolm,   Bill.
This study used information about a farm in the Victorian Mallee during the period 1998 – 2005 to analyse the profitability of investing in Precision Agriculture and Site-Specific Crop Management technology and farming systems. Two equipment guidance systems were evaluated. Both guidance systems earned more than 8 percent real return p.a. on the extra capital invested. A Real-Time Kinetic (RTK) guidance system with a precision of 2 cm and a capital cost of $50,000 was less profitable than a Sub-Metre guidance system with 20 cm accuracy and costing $20,000. Producers investing in RTK guidance technology would be well-paid to also adopt supporting management practices that enhance crop gross margins or provide other benefits. The capital cost of GPS...

A wine market and marketing analysis of Wine Specialities from the Tokaj-Hegyalja Wine District
Provedor de dados: 31
Autores: Szakal,   Zoltan.
Tokaj Wine Specialities have few competitors and enjoy a rare niche among natural dessert wines since traditions surrounding their preparation, their specific microclimate, and unique taste enable one to utilise marketing tools for branding and market placement. To elaborate the marketing strategy, one needs market information that adequately shows the current situation and trends. During my research, I carried out segmentation for Tokaj Wine Specialities consumers and illustrated the correlations with statistical methods. My research covered the North-Alföld Region and Budapest. I performed a reliability test on the research databases and demonstrated that the areal data set can be integrated. My hypotheses findings also constitute new research.

A year-class curve analysis to estimate mortality of Atlantic bluefin tuna caught by the Norwegian fishery from 1956 to 1979
Provedor de dados: 5
Autores: Fromentin, Jean-marc; Restrepo, Victor.
At the ICCAT symposium on bluefin tuna that held in Santander in April 2008, Tangen et al.(2009) presented a first quantification of the fishing effort deployed by the Norwegian fishery targeting bluefin tuna in the North Sea and Norwegian Sea. Using a year-class curve analysis on the Norwegian CPUE, this document presents the first estimates of mortality rates of Atlantic bluefin tuna that migrated north from the mid-1950s to the late 1970s. The results indicate that bluefin tuna would have experienced a total mortality rate (Z) of 0.2 to 0.4 yr-1 (i.e. F at around 0.3 yr-1) during the late 1950s, 0.2 yr-1 during the 1960s and 0.1 yr-1 afterwards (assuming M=0.1 yr-1). These results appear to be rather robust and consistent with the VPA estimates from the...

Abatement and Allocation in the Pilot Phase of the EU ETS
Provedor de dados: 31
Autores: Anderson,   Barry; Di Maria,   Corrado; Convery,   Frank J.
We use historical industrial emissions data to assess the level of abatement and overallocation that took place across European countries during the pilot phase (2005-2007)of the European Union Emission Trading Scheme. Using a dynamic panel data model, we estimate the counterfactual (business-as-usual) emissions scenario for EU member states. Comparing this baseline to allocated and verified emissions, we conclude that both overallocation and abatement occurred, along with under-allocation and emissions inflation. Over the three trading years of the pilot phase we find over-allocation of approximately 376 million EUAs (6%) and total abatement at the member state level of 107 Mt CO2 (1.8%). However, due to over-allocation and possible uncertainty about...

Abiotic alterations caused by forest fragmentation affect tree regeneration: a shade and drought tolerance gradient in the remnants of Coastal Maulino Forest
Provedor de dados: 97
Autores: GUERRERO,PABLO C; BUSTAMANTE,RAMIRO O.
Plant regeneration is strongly determined by light and soil moisture differences between habitáis; both variables are modified by large-scale forest fragmentation. Several studies have indicated this alteration as the mechanism involved in tropical forest community change. The effects of fragmentation may be much more severe in Mediterranean and deciduous forests, because plant species in these forests show a stress tolerance tradeoff between shade and drought. Our study was performed in the deciduous fragmented Coastal Maulino Forest: Reserva Nacional Los Queules (RNLQ) and surrounding small fragments. We hypothesised that Aristotelia chilensis (shade intolerant but drought tolerant) should increase its regeneration in small patches as a consequence of...

Autores: Ferreira,Kátia; Torres,Giovana Augusta; Carvalho,Isabelle Vilela de; Davide,Lisete Chamma.
The objective of this work was to compare the meiotic behavior and pollen grain viability of three species of Crotalaria. Slides for meiotic analysis were prepared by the air-drying technique. Pollen grain viability was measured by three staining procedures (Alexander's solution, tetrazolium chloride and fluorescein diacetate) and in vitro germination in a sucrose solution. Eight bivalents were observed, confirming previous reports on populations from other regions of Brazil, as well as from other countries. All species showed abnormal meiotic behavior as follows: in Crotalaria micans, cytomixis and abnormal chromosome pairing in diakinesis; in C. spectabilis, abnormal chromosome pairing in diplotene; in C. zanzibarica, shrunk nuclei in leptotene and...

Autores: Maldonado Posso, Viviana.
Uno de los temas que ha estado ausente o escasamente abordado en la agenda del movimiento de mujeres del Ecuador, desde la d??cada de los 70??s ha sido el derecho al aborto. En el plano de la defensa y tratamiento de los derechos y salud sexual y reproductiva, el derecho al aborto no se ha constituido en una bandera principal de lucha del movimiento. Sin embargo, no se puede desconocer que algunas integrantes del movimiento y feministas han sostenido la defensa del derecho a decidir sobre su sexualidad y cuerpo.

Aboveground Net Primary Productivity in Grazed and Ungrazed pastures: Grazing Optimisation Hypothesis or Local Extinction of Vegetation Species
Provedor de dados: 17
Autores: Silvanus G. Otieno; Jesse T. Njoka; Truman P. Young; Stephen M. Mureithi; Robinson K. Ngugi.
The controversy that has surrounded herbivory studies in the last few decades prompted our investigation to establish the extent to which herbivore optimisation hypothesis or compensatory growth evidence is real. We used the traditional movable cage method to collect primary productivity data on herbage, functional groups and key individual grass species in various controlled large herbivore treatments in an east African savanna. The herbivore treatments in triplicate blocks included cattle, wild herbivores with and without mega herbivores and combinations of cattle and wild herbivores also with and without mega herbivores. The findings revealed that at herbage level, most grazed treatments (four out of five) had higher productivity than the ungrazed...

Abrupt climate variability during the last glacial and the late Holocene from the western tropical Pacific perspective
Provedor de dados: 5
Autores: Saikku, Reetta Maaria.
In Project I, Western tropical Pacific sea surface temperatures and Pacific Deep Water temperatures during Marine Isotope Stage 3 have been reconstructed from the δ18O and Mg/Ca of planktonic and benthic foraminifera from Marion Dufresne core MD98-2181. This 36m marine core was collected at 6.3°N from a water depth of 2114m. With sediment accumulation rates of up to 80cm/ky, it provides a decadally-resolved history of ocean variability during the last glacial period. Surface temperatures and salinities at this site varied in close association with millennial-scale atmospheric temperature swings at high northern latitudes as reflected in the GISP2 ice core. At times of colder atmospheric temperatures over Greenland, the western Pacific was more saline and...

Autores: Trevisan,André; Hepp,Luiz Ubiratan; Santos,Sandro.
This study investigated the influence of land use and occupation on the density and distribution of aeglids in the hydrographic basin of the Jacutinga river (northern state of Rio Grande do Sul, Brazil). Sampling was carried out during the summer and winter of 2004, at 12 sites distributed in river spring, agriculture, grazing, and urban areas. Animals were collected using a Surber sampler. An analysis of variance (ANOVA) was conducted to evaluate differences in the density of species in each land use and sampling period. Biological data were classified using cluster analysis (Euclidian distance; UPGMA). A total of 226 aeglids were captured, including 167 (78.89%) specimens of Aegla platensis Schmitt, 1942 and 59 (26.11%) specimens of A. singularis...

Com o objetivo de analisar a distribuição temporal de larvas de Pachyurus bonariensis e sua relação com algumas variáveis ambientais, foram feitas coletas na baía Sinhá Mariana, Mato Grosso, entre março/2000 e março/2004, às 16 e 22h. Simultaneamente, amostras de água foram obtidas para determinar temperatura da água, oxigênio dissolvido, pH e condutividade elétrica. As maiores densidades foram verificadas entre os meses de outubro e janeiro, sugerindo ser este o principal período de reprodução da espécie. No entanto, larvas em estágio de pré-flexão e flexão também foram encontradas no inverno, possivelmente associadas às condições favoráveis para a reprodução. Indivíduos de todos os estágios estiveram presentes, ou seja, é provável que todo o ciclo de...

Acanthotylotra alvarengai (Porifera, Demospongiae) new genus and species of sponge from Tocantins river, Pará State, Brazil
Provedor de dados: 76
Autores: Volkmer-Ribeiro,Cecilia; Tavares,Maria da Conceição M; Oliveira,Karina Fürstenau de.
Acanthotylotra a new monotypic genus of freshwater sponge is defined. Its sole species A. alvarengai sp. nov. is described based upon microscopic specimens recovered from the Tocantins river, Pará State, Brazil, when the deep rocky substrate was temporarily exposed downstream from the dam at the time it was closed for lake formation. A unique set of megascleres, allied to the paucity of spongin, the renieroid skeleton and the fact that gemmules or new specimens remain undetected, call for the proposition of a new monospecific genus to be retained as incertae sedis until new larger and probably gemmuliferous specimens come to be found.

Access to Land and Poverty Reduction in Rural Zambia: Connecting the Policy Issues
Provedor de dados: 31
Autores: Jayne,   Thomas S.; Zulu,   Ballard; Kajoba,   Gear; Weber,   Michael T.
Key Policy Message: - Despite having relatively low population densities, inadequate access to land is one of the major causes of rural poverty in Zambia. - The apparent paradox of inadequate access to land for many rural households in a country of low population density is partially reconciled when taking into account that economically viable arable land requires at least some degree of access to basic services, water, road infrastructure, and markets. The basic public investments to make settlement economically viable have yet been made in many areas of Zambia. - Depending of future land allocation policy, access to good quality land with a market potential may become increasingly beyond the reach of many small-scale farm households, making it more...

Accommodating covariates in receiver operating characteristic analysis
Provedor de dados: 31
Autores: Janes,   Holly; Longton,   Gary M.; Pepe,   Margaret S.
Classification accuracy is the ability of a marker or diagnostic test to discriminate between two groups of individuals, cases and controls, and is commonly summarized by using the receiver operating characteristic (ROC) curve. In studies of classification accuracy, there are often covariates that should be incorporated into the ROC analysis. We describe three ways of using covariate information. For factors that affect marker observations among controls, we present a method for covariate adjustment. For factors that affect discrimination (i.e., the ROC curve), we describe methods for modeling the ROC curve as a function of covariates. Finally, for factors that contribute to discrimination, we propose combining the marker and covariate information, and we...

Autores: Steenstra,   Alex.
This paper examines how cultural values are accommodated in natural resource management and compares and contrast the approaches used in the Waikato River in New Zealand, the Murray-Darling Basin in Australia, and the Colorado River in the USA. Economics plays an integral part in the management of rivers in these case studies and two distinct approaches are used; privatization and co-management. The paper reviews these approaches and proffers suggestions on how indigenous knowledge, cultural and social relationships, and social, cultural, and economic wellbeing may be integrated in a multi-cultural approach.

Accounting for molecular stochasticity in systematic revisions: species limits and phylogeny of Paroaria
Provedor de dados: 17
Autores: Liliana M. D&amp;#xe1;valos; Ana L. Porzecanski.
Different frameworks have been proposed for using molecular data in systematic revisions, but there is ongoing debate on their applicability, merits and shortcomings. In this paper we examine the fit between morphological and molecular data in the systematic revision of Paroaria, a group of conspicuous songbirds endemic to South America. We delimited species based on examination of &amp;#x3e; 600 specimens, and developed distance-gap, and distance- and character-based coalescent simulations to test species limits with molecular data. The morphological and molecular data collected were then analyzed using parsimony, maximum likelihood, and Bayesian phylogenetics. The simulations were better at evaluating the new species limits than using genetic distances....

Accounting for Respondent Uncertainty to Improve Willingness-to-Pay Estimates
Provedor de dados: 31
Autores: Moore,   Rebecca; Bishop,   Richard C.; Provencher,   Bill; Champ,   Patricia A.
In this paper we develop an econometric model of willingness to pay that integrates data on respondent uncertainty regarding their own willingness to pay. The integration is utility consistent and does not involve calibrating the contingent responses to actual payment data, and so the approach can “stand alone”. In an application to a valuation study related to whooping crane restoration, we find that this model generates a statistically lower expected WTP than the standard CV model. Moreover, the WTP function estimated with this model is not statistically different from that estimated using actual payment data, suggesting that when properly analyzed using data on respondent uncertainty, contingent valuation decisions can simulate actual payment decisions....

Accumulation and fragmentation of plastic debris in global environments
Provedor de dados: 5
Autores: Barnes, David K. A.; Galgani, Francois; Thompson, Richard C.; Barlaz, Morton.
One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up operations, costing millions of pounds sterling, are now organized in many countries and on every continent. Here we document global plastics production and the accumulation of plastic waste. While plastics typically constitute approximately 10 per cent of discarded waste, they represent a much greater proportion of the debris accumulating on shorelines. Mega- and...

Accurate telemonitoring of Parkinson&amp;#x2019;s disease progression by non-invasive speech tests
Provedor de dados: 17
Autores: Athanasios Tsanas; Max A. Little; Patrick E. McSharry; Lorraine O. Ramig.
Tracking Parkinson&amp;#x27;s disease (PD) symptom progression often uses the Unified Parkinson&amp;#x2019;s Disease Rating Scale (UPDRS), which requires the patient&amp;#x27;s presence in clinic, and time-consuming physical examinations by trained medical staff. Thus, symptom monitoring is costly and logistically inconvenient for patient and clinical staff alike, also hindering recruitment for future large-scale clinical trials. Here, for the first time, we demonstrate rapid, remote replication of UPDRS assessment with clinically useful accuracy (about 7.5 UPDRS points difference from the clinicians&amp;#x2019; estimates), using only simple, self-administered, and non-invasive speech tests. We characterize speech with signal processing algorithms,...

ACIAR’s 25 year investment in fruit-fly research
Provedor de dados: 31
Autores: Lindner,   Robert K.; McLeod,   Paul.
Fruit flies are recognised as one of the major pests of fruit and vegetable crops worldwide. Potential benefits from fruit fly research include biosecurity benefits from better quarantine surveillance that reduces the costs of an incursion by a damaging exotic pest fruit fly; market access benefits by enabling new fruit exports; and field control benefits from better crop management. The Australian Centre for International Agricultural Research (ACIAR)’s investment in fruitfly research goes back some 25 years to an initial project in Malaysia. Since that time, ACIAR’s continued investment has funded a total of 18 projects ranging across several areas of fruit-fly research, and covering Malaysia, Thailand, Philippines, Fiji Islands, Samoa, Tonga, Cook...

Acidic polysaccharides from Psidium cattleianum (Araçá)
Provedor de dados: 52
Autores: Vriesmann,Lúcia Cristina; Petkowicz,Carmen Lúcia de Oliveira; Carneiro,Paulo Irajara Borba; Costa,Maria Eugênia; Beleski-Carneiro,Eliana.
The aim of this work was to study the acidic polysaccharides of Psidium cattleianum. Pectic fractions were obtained by successive extractions with water, EDTA and sodium carbonate (4 and 25ºC). Monosaccharide composition, total carbohydrates, uronic acids and protein contents were determined for each fraction. The yield of water and EDTA-soluble fractions and high content of uronic acid were consistent with the presence of pectins probably arising from the middle lamellae. On the other hand, sodium carbonate-soluble pectins had a higher neutral sugar content, indicating highly branched polysaccharides in these fractions, consistent with pectins from cell wall.

Are flower-strips composed of arable field plants a tool to integrate rare species into  organic fields? In the surrounding of the Hessian State Domain Frankenhausen seeds  of rare annual field plants were collected and reproduced. The autochthonous seeds  and also the corn-cockle have been integrated into a mixture that has been tested to  which extent the flower-strips are able to suppress soil-borne weed species. The  vegetation of the arable field plant strips has been monitored by phytosociological  relevees. A certain amount of seeds is needed to reach satisfactory results. The corncockle  affords special management because of its biology and its possible toxicity.

Porpoise echolocation has been studied previously, mainly in target detection experiments using stationed animals and steel sphere targets, but little is known about the acoustic behaviour of free-swimming porpoises echolocating for prey. Here, we used small onboard sound and orientation recording tags to study the echolocation behaviour of free-swimming trained porpoises as they caught dead, freely drifting fish. We analysed porpoise echolocation behaviour leading up to and following prey capture events, including variability in echolocation in response to vision restriction, prey species, and individual porpoise tested. The porpoises produced echolocation clicks as they searched for the fish, followed by fast-repetition-rate clicks (echolocation buzzes)...

ACRE: A Revenue-Based Alternative to Price-Based Commodity Payment Programs
Provedor de dados: 31
Autores: Cooper,   Joseph C.
This paper develops a stochastic model for estimating the probability density function of the Average Crop Revenue Election (ACRE), a revenue-based commodity support payment that is offered under the 2008 Farm Act as an alternative to the traditional suite of price-based commodity payments, that is, marketing loan benefits and counter-cyclical payments.  We minimize the potential for miss-specification bias in the model by using nonparametric and semi-nonparametric approaches as specification checks in the model. Our simulation results show that adding ACRE revenue payments to gross revenue reduced the downside risk in revenue for corn, wheat, and soybean farmers in 2009 in the four locations examined, with reductions ranging from 4% to 25%.   Integrating...

Estimated ACRE revenue payments increase 78 percent when calculated by applying the annual 1996-2006 percentage variations to USDA forecast average 2009-2012 acres, prices, and yields. Traditional marketing loan and counter-cyclical payments are estimated near zero. Policy design issues concern the merit of revenue versus price protection, fixed support targets versus support adjusting with lagged market revenue, and the economic dislocation and WTO compliance from alternative policy instruments.

Acrylamid-Bildungspotenzial ökologisch erzeugter Getreidearten  und Sorten
Provedor de dados: 21
Autores: Stockmann, Falko; Mast, Benjamin; Graeff, Dr. Simone; Claupein, Prof. Dr. Wilhelm.
By heating up carbohydrate-rich food, like cereals and potatoes, Acrylamide (AA), a  probably carcinogen food ingredient, will be created due to a reaction of free Asparagine  (Asn) and reducing sugar within the Maillard-Reaction. Up to now two opportunities  to decrease AA are discussed. Firstly by changing technological food processing  steps e.g. receipt modifications and secondly by plant production e.g. finding species  and cultivars low in the content of precursors of AA. For cereals, free Asn is the limiting  factor for formation of AA. By investigations of conventionally produced wheat-,  spelt- and rye samples differences were found in the amount of Asn both in species  and cultivars. It was assumed that these differences could also be found in...

Act to Save Groundwater in Punjab: Its Impact on Water Table, Electricity Subsidy and Environment
Provedor de dados: 31
Autores: Singh,   Karam.
The fall in water table in Punjab has been a serious issue. One of the main reasons for it has been the early transplanting of rice (before mid-June), which means severe withdrawal of groundwater, as the monsoon is still far away, temperatures are very high and evapo-transpiration rate (ETR) is maximum. On the initiative of the Punjab State Farmers Commission, “The Punjab Preservation of Sub Soil Water Act” (not to sow paddy nursery before May 10 and not to transplant paddy before June 10) was promulgated as an Ordinance in 2008 and encouraged by the response, it has been changed into an Act in March 2009. The time series and experimental data on transplanting pattern, water requirements rice, rainfall, monsoon recharge, groundwater behaviour and rice area...

Actin-interacting and flagellar proteins in Leishmania spp.: bioinformatics predictions to functional assignments in phagosome formation
Provedor de dados: 74
Autores: Diniz,Michely C.; Costa,Marcília P.; Pacheco,Ana C.L.; Kamimura,Michel T.; Silva,Samara C.; Carneiro,Laura D.G.; Sousa,Ana P.L.; Soares,Carlos E.A.; Souza,Celeste S.F.; Oliveira,Diana Magalhães de.
Several motile processes are responsible for the movement of proteins into and within the flagellar membrane, but little is known about the process by which specific proteins (either actin-associated or not) are targeted to protozoan flagellar membranes. Actin is a major cytoskeleton protein, while polymerization and depolymerization of parasite actin and actin-interacting proteins (AIPs) during both processes of motility and host cell entry might be key events for successful infection. For a better understanding the eukaryotic flagellar dynamics, we have surveyed genomes, transcriptomes and proteomes of pathogenic Leishmania spp. to identify pertinent genes/proteins and to build in silico models to properly address their putative roles in trypanosomatid...

Action of plant proteinase inhibitors on enzymes of physiopathological importance
Provedor de dados: 42
Autores: Oliva,Maria Luiza V.; Sampaio,Misako U.
Obtained from leguminous seeds, various plant proteins inhibit animal proteinases, including human, and can be considered for the development of compounds with biological activity. Inhibitors from the Bowman-Birk and plant Kunitz-type family have been characterized by proteinase specificity, primary structure and reactive site. Our group mostly studies the genus Bauhinia, mainly the species bauhinioides, rufa, ungulata and variegata. In some species, more than one inhibitor was characterized, exhibiting different properties. Although proteins from this group share high structural similarity, they present differences in proteinase inhibition, explored in studies using diverse biological models.

Breast cancer is known to be a hormone-dependent disease, and estrogens through an interaction with estrogen receptor (ER) enhance the proliferative and metastatic activity of breast tumor cells. Here we show a critical role of transactivation of BIG3, brefeldin A-inhibited guanine nucleotide-exchange protein 3, in activation of the estrogen/ER signaling in breast cancer cells. Knocking-down of BIG3 expression with small-interfering RNA (siRNA) drastically suppressed the growth of breast cancer cells. Subsequent co-immunoprecipitation and immunoblotting assays revealed an interaction of BIG3 with prohibitin 2/repressor of estrogen receptor activity (PHB2/REA). When BIG3 was absent, stimulation of estradiol caused the translocation of PHB2/REA to the...

The dimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human granulomatous disease. Recently the first case of natural disease in dogs was reported. The complement system is an important effector component of humoral immunity against infectious agents. Therefore, the aim of this study was to evaluate the activation of the dog alternative complement pathway by P. brasiliensis. Initially, the ability of erythrocytes of guinea pig, rabbit, sheep, chicken and swine to activate the dog alternative pathway was evaluated. The guinea pig erythrocytes showed the greatest capacity to activate dog alternative pathway. The alternative (AH50) hemolytic activity was evaluated in 27 serum samples from healthy dogs and the...

Activity of cellulase from Thermoactinomycetes and Bacillus spp. isolated from Brassica waste compost
Provedor de dados: 63
Autores: Chang,Chen-Chin; Ng,Chang-Chai; Wang,Chung-Yi; Shyu,Yuan-Tay.
Plant wastes present a high cellulose content, which is an ideal organic material for composting. Five strains of thermophiles from processed Brassica waste were isolated, and the hydrolytic activity on various cellulosic biomass substrata and their temperature profiles were determined. 16S rRNA sequencing identified these strains as Thermoactinomyces and Bacillus spp. Maximal cellulase activity corresponded to 2.3 U mL-1 of enzyme. The application of these strains on Brassica rapa residues demonstrates increased total nitrogen content). TA-3, a Thermoactinomycetes sp. strain, performs best among all inoculants, increasing the nitrogen content from 0.74 to 0.91%, and decreasing the carbon content from 15.4 to 12.2%, showing its high efficiency and...

Actores y ambientalismos : conflictos socio-ambientales en Perú (Temas) = Actors and environmentalism : socio-environmental conflicts in Peru
Provedor de dados: 122
Autores: Bebbington, Anthony; Humphreys Bebbington, Denise.
Este artículo identifica cinco tipos de ambientalismos que están presentes en los conflictos mineros en el Perú: el conservacionista, el nacionalista-populista, el de defensa de las formas de vida, el de justicia socio-ambiental y el ecologismo profundo. Se sugiere que cada ambientalismo conlleva diferentes salidas a los conflictos ambientales: la compensación en unos casos o el debate público abierto y franco ean otros. Es esta segunda salida la que promovería un fortalecimiento de la democracia.

El trabajo infantil es una de las problemáticas en torno a la cual se pueden observar en plena acción los tres grandes tipos de políticas que históricamente ha asumido la asistencia, como objeto de prácticas especializadas, desde principios distintos: la caridad, la filantropía y la intervención estatal. Pero al mismo tiempo que estas políticas se contraponen entre ellas, se enfrentan a la resistencia de actores que tradicionalmente no conciben las actividades de los niños/as como un problema sino como parte de su socialización, lo que constituye una nueva fuente de asimetrías entre la modernidad occidental y las demás culturas (B.Latour, 1991).

Objetivou-se comparar a dinâmica do acúmulo de forragem em pastos de capim-xaraés [Brachiaria brizantha (A. Rich.) Stapf. cv. Xaraés] submetidos a três estratégias de desfolhação intermitente, uma baseada no calendário (pastejo a cada 28 dias) e duas na interceptação luminosa (IL), aos 95 ou 100% de interceptação luminosa. A massa de forragem (MF) pré-pastejo foi maior na estratégia de desfolhação aos 100% de interceptação de luz. Os piquetes pastejados aos 95% de interceptação de luz e a cada 28 dias apresentaram menores massas de forragem e não diferiram entre si na primavera. O pastejo aos 95% de interceptação de luz aumentou a proporção de folhas, apesar das menores massas pré-pastejo. O pastejo aos 100% de interceptação de luz resultou na menor...

Acupuntura e analgesia: aplicações clínicas e principais acupontos
Provedor de dados: 65
Autores: Taffarel,Marilda Onghero; Freitas,Patricia Maria Coletto.
A dor é uma resposta protetora do organismo a estímulos nocivos, que resulta em efeitos indesejáveis quando não controlada. A analgesia pode ser promovida mediante a utilização de vários tipos de fármacos. No entanto, estes podem causar efeitos adversos de acordo com a espécie e condição física do paciente. A acupuntura tem se mostrado eficaz como coanalgésico pela capacidade de diminuir a quantidade de fármacos utilizados para o controle da dor e raramente ser contraindicada. Objetivou-se com este trabalho fazer uma breve revisão sobre as aplicações clínicas e os efeitos fisiológicos da acupuntura nos mecanismos da dor, bem como demonstrar os principais pontos de acupuntura utilizados para analgesia em animais.

Acute and chronic electrical activation of baroreceptor afferents in awake and anesthetized subjects
Provedor de dados: 56
Autores: Durand,M.T.; Fazan Jr.,R.; Salgado,M.C.O.; Salgado,H.C.
Electrical stimulation of baroreceptor afferents was used in the 1960's in several species, including human beings, for the treatment of refractory hypertension. This approach bypasses the site of baroreceptor mechanosensory transduction. Chronic electrical stimulation of arterial baroreceptors, particularly of the carotid sinus nerve (Hering's nerve), was proposed as an ultimate effort to treat refractory hypertension and angina pectoris due to the limited nature of pharmacological therapy available at that time. Nevertheless, this approach was abandoned in the early 1970's due to technical limitations of implantable devices and to the development of better-tolerated antihypertensive medications. More recently, our laboratory developed the technique of...

Venom of the South American rattlesnake, Crotalus durissus terrificus (Cdt), presents myotoxic and neurotoxic outcomes, but reports on its effects on the liver are scarce. This study examined the hepatotoxicity resulting from Cdt venom administration (100, 200 and 300 µg/kg) in male Wistar rats. Animals were studies at 3, 6, 9 and 12 hours after venom injection. The hepatotoxicity was assessed through serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), gamma glutamyl transferase (GGT), bilirrubin and also by histopathological evaluation. All the different concentrations of Cdt venom resulted in increased levels of hepatic enzymes, when compared with the control group, except for the 100 µg/kg dose,...

Autores: Porto,Willyam Stern; Carvalho,Claudio Guilherme Portela de; Pinto,Ronald José Bart; Oliveira,Marcelo Fernandes de; Oliveira,Ana Cláudia Barneche de.
O sucesso da cultura do girassol (Helianthus annuus L.) no Brasil está associado à escolha adequada de cultivares com adaptação a diferentes ambientes. Quando há respostas diferenciadas dos genótipos testados nos diferentes ambientes, a decisão de lançamento de novas cultivares pode ser facilitada com estudos de adaptabilidade e estabilidade desses genótipos para reduzir os efeitos da interação genótipos x ambientes. No país, essas informações tornam-se mais importantes, pois a maioria das cultivares utilizadas, ou em lançamento, foram desenvolvidas em outros países, com características de solo e clima diferentes. Este trabalho teve como objetivo estudar a adaptabilidade e estabilidade de genótipos de girassol na região subtropical do Brasil, uma das...

Autores: Bdioui, M.; M'Rabet, R.
Le présent travail concerne l’adaptation et l’essai d’un chalut pélagique japonais de très grandes mailles et à quatre faces égales dans les pêcheries tunisiennes. Le fil élémentaire composant les alèzes de filets est en Dyneema. Les essais de ce modèle de chalut, conçu pour un bateau d’une puissance motrice de 650 C.V, ont montré qu’il est adapté aux pêcheries de la région nord de la Tunisie et qu’il est efficace pour la capture des petits poissons pélagiques de grande profondeur notamment la sardine et l’anchois. Par ailleurs, les rendements de ce modèle de chalut sont importants grâce à ses ouvertures, horizontale et verticale, d’environ 35mètres. Les captures sont composées à plus de 99% d’espèces pélagiques.

The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic...

Adaptations of lichens to conditions in tropical forests of South-East Asia and their taxonomic implications
Provedor de dados: 16
Autores: Wolseley, P.A.; Hawksworth, D.L.
Lichens are fungi with a specialized nutritional mode involving algae, or cyanobacteria, or both. Classification is based on the fungal partner, and around 13 500 species are known. The association is ancient, and the first ascomycete fungi with fruit bodies may have been lichenized. Adaptations to tropical habitats include extensive utilization of trentepohlioid algae, the production of large multi-celled spores capable of forming numerous germ tubes, and water-repellant hydophobins coating internal cell walls. Many tropical groups lack modern monographs and numerous new species are discovered in detailed studies. Lichens merit more attention in the tropics as bioindicators of habitat disturbance.

ADAPTING MORE CLEVERLY TO CLIMATE CHANGE BY USING ‘REAL OPTIONS’ TO ADDRESS THE UNCERTAINTIES
Provedor de dados: 31
Autores: Dobes,   Leo.
Scientists consider that some climate change is already inevitable, even if anthropogenic greenhouse emissions are stabilised immediately. Adaptation measures are therefore needed, irrespective of any mitigation action. But policy discussion is focussed on deterministic responses, generally risk-based "worst case‟ scenarios. An example is the development of more stringent standards for buildings and for coastal development. Such "climate proofing‟ is misconceived in the face of the huge uncertainties involved. Economists need to promote more rational policy frameworks that draw on cost-benefit analysis, including the use of "real options‟ to minimise the cost to society of adapting to climate change.

Adaptive and cross-protective responses against cadmium and zinc toxicity in cadmium-resistant bacterium isolated from a zinc mine
Provedor de dados: 58
Autores: Prapagdee,Benjaphorn; Watcharamusik,Anchulee.
Cadmium (Cd) is a major environmental hazard, which usually is detected in its ionic form of Cd2+. It also causes adverse toxic effects on human health and other living organisms. Cd-resistant bacteria were isolated from Cd-contaminated soils. One isolate, TAK1, was highly resistance level to Cd toxicity. TAK1 was isolated from soil contaminated with a high Cd concentration (204.1 mg.kg-1). The result of 16S rDNA sequence analysis found that the TAK1 showed the similarity to Ralstonia sp. Physiological adaptive and cross-protective responses to Cd and Zn killing were investigated in Ralstonia sp.TAK1. Exposure to a low concentration of Cd induced adaptive resistance to higher concentrations of Cd. In addition, pretreatment of Ralstonia sp.TAK1 with an...

Adaptive Experimental Design Using the Propensity Score
Provedor de dados: 31
Autores: Hahn,   Jinyong; Hirano,   Keisuke; Karlan,   Dean S.
Many social experiments are run in multiple waves, or are replications of earlier social experiments. In principle, the sampling design can be modified in later stages or replications to allow for more efficient estimation of causal effects. We consider the design of a two-stage experiment for estimating an average treatment effect, when covariate information is available for experimental subjects. We use data from the first stage to choose a conditional treatment assignment rule for units in the second stage of the experiment. This amounts to choosing the propensity score, the conditional probability of treatment given covariates. We propose to select the propensity score to minimize the asymptotic variance bound for estimating the average treatment...

This article assesses the institutional prescriptions of adaptive (co-)management based on a literature review of the (water) governance literature. The adaptive (co-)management literature contains four institutional prescriptions: collaboration in a polycentric governance system, public participation, an experimental approach to resource management, and management at the bioregional scale. These prescriptions largely resonate with the theoretical and empirical insights embedded in the (water) governance literature. However, this literature also predicts various problems. In particular, attention is called to the complexities associated with participation and collaboration, the difficulty of experimenting in a real-world setting, and the politicized nature...

Autores: Napitupulu,   Togar Alam; Natawidjaja,   Ronnie S.
The current trend in world trade of agro-food, and the change in consumer demand patterns for food and agricultural products, has led to a fast growth of multi-national chains of retail stores in major cities in developing countries and growth in domestic retail store chains. Their presence opens a new market for high quality agro-food. While many products come from overseas, many can also be supplied locally by farmers or farmers’ co-operatives or associations provided that they meet the quality and supply standards required by the store. To study and identify specific benefits from this global economic trend that can be tapped by secondary crops farmers, specifically those living in medium altitude areas, two studies were conducted in two member...

Present-day conservation policies generally include the aim to integrate biodiversity conservation and local development, and describe this as a win&amp;#8211;win solution that can satisfy all interests. This is challenged by research claiming that many efforts fail to match practice to rhetoric. South Africa has made strong commitments to fulfill the dual goals of conservation and development, and the iSimangaliso Wetland Park is promoted as an example of this. We explore present and potential outcomes of conservation and development interventions in a community bordering the Wetland Park through the perspective of different stakeholders, with the aim of uncovering opportunities and risks.

In this study we investigated the phenotypic slime production of Vibrio alginolyticus and Vibrio parahaemolyticus strains, food-borne pathogens, using a Congo red agar plate assay. Furthermore, we studied their ability to adhere to abiotic surfaces and Vero cells line. Our results showed that only V. alginolyticus ATCC 17749 was a slime-producer developing almost black colonies on Congo red agar plate. Adherence to glace tube showed that all V. alginolyticus strains were more adherent than V. parahaemolyticus. Only V. alginolyticus ATCC 17749 was found to be able to form biofilm on polystyrene microplate wells (OD570 = 0.532). Adherence to Vero cells showed that all tested strains were non adherent after 30 min, however after 60 min all the studied strains...

ADME/Tox WEB in silico predictions of longer chain perfluoroalkyl carboxylic acid pKa values are more accurate than other computational methods
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
Perfluoroalkyl carboxylates are contaminants whose environmental fate and toxicological effects are of broad interest within the academic, industrial, and governmental science and regulatory communities. In addition, coupled perfluoroalkyl and carboxylate moieties are often used in medicinal chemistry as part of the drug design process. However, to date there has been a notable absence of reliable acidity constant estimation programs for these compounds. Here we report that the ADME/Tox WEB method for in silico pKa value predictions is more accurate than the PM6, SPARC, and COSMOtherm methods for the longer chain perfluoroalkyl carboxylic acids, suggesting this may be a good general acidity constant estimation approach for these compounds.

Adoption and Abandonment of Organic Farming: An Empirical Investigation of the Irish Drystock Sector
Provedor de dados: 31
Autores: Lapple,   Doris; Donnellan,   Trevor.
The adoption and possible abandonment of organic farming has yet received little attention in the literature. As time plays an important role in explaining farming decisions, a dynamic econometric framework, namely duration analysis, is used. The probability of entry to and exit of the organic drystock sector is modeled considering a wide range of economic and non‐economic factors. Organic support payments emerge as important driving factor of adoption over time. The empirical results also highlight the importance of environmental and risk attitudes, farming experience as well as influence of other organic farmers on the probability to adopt organic farming; whereas decisions to abandon organic farming appear to be mainly driven by economic and structural...

Adoption and impact of an award winning post-harvest technology: The ASI rice thresher in the Senegal River Valley
Provedor de dados: 31
Autores: Diagne,   Mandiaye; Demont,   Matty; Diagne,   Aliou.
In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved technologies like the ASI thresher-cleaner. The causal or treatment effect framework (ATE and LATE) is used to estimate the ASI adoption rate and impact. The results show that the true ASI adoption rate would be 86 % if all the population of irrigated rice farmers were exposed to it. The socioeconomic characteristics that increase the probability to adopt the ASI thresher are farmer experience, farm size, and participation to ASI field experiments and/or contact...

Autores: Frisvold,   George B.; Hurley,   Terrance M.; Mitchell,   Paul D.
This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit regressions were used to explain the frequency of individual BMP adoption. Growers practicing a greater number of BMPs frequently (a) had more education, but less farming experience; (b) grew cotton, (c) expected higher yields relative to the county average; and (d) farmed in counties with a lower coefficient of variation (CV) for yield of their primary crop. Yield expectations and variability were significant predictors of the frequency of adoption of individual...

Rising concerns about the environmental costs of dairy production have resulted in an increasing use of farm practices that diminish negative production externalities. Yet, little empirical evidence exists regarding the factors influencing the adoption of pollution-reducing strategies by dairy farmers. In this study, we estímate a logit probability model to explain first-stage adoption of capital-intensive cleaner production (CP) practices, using a sample of 100 médium and large-size dairy farms located in southern Chile. Voluntary approaches to pollution control in agriculture are relatively recent in Chile and diffusion has been slow and uneven among farmers. Only 43% of the farmers surveyed were using some CP practices at the time of the interview. The...

China has experienced frequently food safety scares due to pesticide residue issues in recent years. This excessive of illegal use is often tied to numerous small-scale farmers. As it is a great challenge for Chinese government to monitor production practices of small-scale farmers directly, encouraging the adoption of food safety and quality standards by China’s agricultural cooperatives serves as an alternative approach to monitor the production practices of the small-scale farmers, and thus ensure improved quality of foods they produce. Based on the survey data from 124 vegetable cooperatives in Zhejiang Province, this study is designed to analyze the factors that affect adoption of food safety and quality standards by agricultural cooperatives in...

Adoption of simultaneous different strategies against different  opponents enhances cooperation
Provedor de dados: 17
Autores: Lucas Wardil; Jafferson  K. L. da Silva.
The emergence of cooperation has been widely studied in the context of game theory on  structured populations. Usually the individuals adopt one strategy against all their neighbors. The structure can provide reproductive success for the cooperative strategy, at least for low values of defection tendency. Other mechanisms, such punishment, can also be responsible for  cooperation emergence. But what happens if the players adopt simultaneously different strategies against each one of their opponents, not just a single one? Here we study this question in the prisoner dilemma scenario structured on a square lattice and on a ring. We show that if an update rule is defined in which the players replace the  strategy that furnishes the smallest payoff,  a...

A capacidade de adsorção de cobre pelo solo é um dado importante em estudos de movimentação de solutos uma vez que, se a capacidade adsortiva de um solo for ultrapassada, o metal ficará potencialmente disponível para ser lixiviado. Neste trabalho se analisam o comportamento da adsorção de cobre face às diferentes características de amostras de Plintossolo e a influência da variação de pH na adsorção do cobre, verificando-se a adequação das equações de Langmuir e Freundlich para descrever a adsorção deste elemento. Soluções de cloreto de cobre foram utilizadas nas concentrações 6, 10, 20, 40, 60 e 80 mg L-1 ajustadas a pH 4,0, 5,0 e 6,0. Os teores de matéria orgânica e a capacidade de troca catiônica das amostras de solo compõem as propriedades que mais...

This work was carried out to study the effects of adult feeding and mating on the biological potential and parasitism of Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae) to improve their use in biological control programs. Both species presented higher parasitism and longevity whenever adults were fed. Fed and unmated T. pretiosum females led to low parasitism whereas T. acacioi females did not present parasitism whatsoever. Egg viability of T. pretiosum was similar for fed and mated individuals, but T acacioi showed lower values for this parameter when unfed and without mating. Unmated females produced only males while mated ones had more than 60% female descendents for both Trichogramma species. Therefore, mated and fed female...

Autores: Kidd,Michael T.
Nutritional advances as discussed in these proceedings embrace historical perspective as well as futuristic perspectives. Indeed, we must have a clear understanding of the past to identify key "advances" that will mold the future of poultry nutrition. Early nutrition research is discussed with reference to in ovo nutrition and nutritional needs up to day seven post-hatch. In addition, the nutrition of the hen is key in early nutrition of chicks. Key advances that have impacted diet formulation are energy and nutrient liberating enzymes, and the use of L-threonine. Key nutritional mechanisms that have been elucidated the past two decades include nutrition in immunity and gut health. Advances in nutritional specifications for specific genetic strains of...

Adventitious shoots from nodule cluster cultures of Vriesea reitzii: an endemic and endangered bromeliad from atlantic forest
Provedor de dados: 65
Autores: Rech Filho,Arlindo; Vesco,Lírio Luiz Dal; Guerra,Miguel Pedro.
The Atlantic Forest is a biome with megadiversity and a number of bromeliads take part of it. This is the case of Vriesea reitzii, an endemic bromeliad threatened with extinction. Tissue culture techniques are valuable tools for the mass propagation of bromeliads, thus reducing pressure in the natural habitat. The aim of the present work was to establish an in vitro protocol based on the induction and proliferation of nodule cluster cultures of this species. Plantlets maintained in MS liquid culture medium plus NAA (2µM) and BAP (4µM) had the basal regions of leaves excised and then inoculated in gelled with agar (7g L-1) MS culture medium plus with Dicamba (2.5; 5; 10; 20 e 30µM) and Kin (2µM) or free of plant growth regulators. Nodule cluster cultures...

Adverse Effects of Trichothiodystrophy DNA Repair and Transcription Gene Abnormalities on Human Fetal Development
Provedor de dados: 17
Autores: Roxana  Moslehi; Caroline Signore; James Troendle; Amiran Dzutsev; James L. Mills.
The effects of DNA repair and transcription genes in human prenatal life have never been studied. Trichothiodystrophy (TTD) is a rare (affected frequency of 10^-6^) recessive disorder caused by mutations in genes involved in the nucleotide excision repair (NER) pathway and in transcription. Based on our clinical observations, we conducted a genetic epidemiologic study to investigate gestational outcomes associated with TTD. We compared pregnancies resulting in TTD-affected offspring (N=24) with respect to abnormalities in their antenatal and neonatal periods to pregnancies resulting in their unaffected siblings (N=18), accounting for correlation, and to population reference values. Significantly higher incidence of several severe gestational complications...

Adverse Selection in the Environmental Stewardship Scheme: Does the Higher Level Entry Scheme Design Reduce Adverse Selection?
Provedor de dados: 31
Autores: Quillerou,   Emmanuelle; Fraser,   Rob W.
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on agricultural foregone income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the scheme. However, the Higher Level Scheme (HLS) design includes some features that potentially reduce adverse selection. This paper studies the adverse selection problem of the HLS using a principal agent framework at the regional level. It is found that, at the regional level, the enrolment of more land from lower payment regions for a given budget constraint has led to a greater overall contracted area (and thus potential...

Adversity and the Propensity to Fail: The Impact of Disaster Payments and Multiple Peril Crop Insurance on U.S. Farm Exit Rates
Provedor de dados: 31
Autores: Kirwan,   Barrett E.
This paper investigates the effect of government-provided crop insurance on farm failure rates. By exploiting random variation in weather and the Federal Crop Insurance Reform Act of 1994, which mandated crop insurance coverage for the first time, I employ two natural experiments that identify the causal effect of disaster relief on farm failure rates. I examine the survival smoothing contribution of crop insurance by looking at the relative effect of disaster relief across two regimes, pre- and post-1994. Prior to 1994 ad hoc, ex post disaster payments were the primary form of disaster relief. Shortly after the 1994 Act virtually all disaster relief came through crop insurance indemnities. I find that disaster relief in the form of ad hoc disaster...

Aerial Spray Deposition on Corn Silks Applied at High and Low Spray Rates
Provedor de dados: 111
Autores: Bradley K Fritz; USDA-ARS.
 Corn earworm is a major pest of sweet corn, especially when grown organically. Aerial application of insecticides is important for both conventionally- and organically-grown sweet corn production as sweet corn is frequently irrigated to assure return on investment given the high production costs. Aerial insecticide application costs can be minimized through use of reduced spray rates if insecticide efficacy can be maintained at the lower spray rates. The objectives of the study were to characterize deposition on field corn silks when applied at 47.9 L/ha (with VMDs at 230 and 400 μm) and 86.2 L/ha (with VMD at 400 μm) spray rates. Applications of the bioinsecticide, Gemstar®, and the insecticide, Entrust®, which are both approved for use in organic...

The objective of this study was to isolate and identify the aerobic bacterial microflora from the oral cavity mucosa and cloaca's samples, collected from Broad-snouted caiman (Caiman latirostris), born and bred in captivity at Parque Zoológico Arruda Câmara, João Pessoa, Paraíba, Brazil. The most common bacteria were Staphylococcus sp. (14.74%), Corynebacterium sp. (13.68%), Escherichia coli (13.68%) and Shigella sp. (11.58%), and the less common were Citrobacter sp. (1.05%), Klebsiella pneumoniae (1.05%) and Salmonella sp. (1.05%).This emphasizes the importance of these microorganisms' participation in infectious processes (sepsis) and injuries caused by crocodilians.

Aerobic removal of stigmasterol contained in kraft mill effluents
Provedor de dados: 69
Autores: Chamorro,Soledad; Xavier,Claudia Regina; Hernández,Victor; Becerra,José; Vidal,Gladys.
Kraft mill effluent, due to its organic matter content and acute toxicity, must be treated. A primary treatment followed by a secondary treatment is the most common system. Aerated lagoon is also considered an effective biological treatment, although this technology has some drawbacks related with operation parameters and land extension space. Moreover, the recovery efficiency for micropollutants contained in kraft mill effluent is questioned due to the anoxic zone in the system. The goal of this work is to evaluate the performance of the aerated lagoon to remove stigmasterol contained in kraft mill effluents. Kraft mill effluent was treated by an aerated lagoon (AL), which was operated with three different stigmasterol load rates (SLR = 0.2, 0.6 and 1.1...

Aerobic Rice: Benefits without going to the Gym?
Provedor de dados: 31
Autores: Bayot,   Ruvicyn; Templeton,   Deborah J.
Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2‐3 times more water per unit of grain produced than crops such as wheat and maize. With growing populations, increased urbanisation and environmental degradation, the supply of fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to develop water‐efficient aerobic rice technologies. This paper highlights the success of that project.

African hunt for investment: any chance for success?
Provedor de dados: 31
Autores: Dyakov,   Ignaty.
During recent two decades the world has witnessed a drastic increase in global FDI inflows. Gradually more and more investment has been directed to the developing countries in the attempt to diversify portfolios and use finance in the most efficient way. Not all developing regions of the world perfectly succeeded in attracting FDI. Large by labor force and territory, abundant in natural resources Sub-Saharan Africa could perform much better in this aspect. This paper once again reviews the opportunities for FDI in Africa and suggests possible ways for authorities of African states to overcome the existing situation.

African monsoon enhancement during the penultimate glacial period (MIS 6.5 similar to 170 ka) and its atmospheric impact
Provedor de dados: 5
Autores: Tisserand, Amandine; Malaize, Bruno; Jullien, Elsa; Zaragosi, Sebastien; Charlier, Karine; Grousset, Francis.
A reconstruction of northwest African summer monsoon strength during the cold marine isotopic stage (MIS) 6 indicates a link to the seasonal migration of the Intertropical Convergence Zone (ITCZ). High-resolution studies of eolian dust supply and sea surface temperature recorded in marine core MD03-2705, on the Mauritanian margin, provide a better understanding about the penultimate glacial history of northwestern African aridity/humidity and upwelling coastal activity. Today, site MD03-2705 experiences increased upwelling and dust flux during the winter months, when the ITCZ is in a southerly position. Analyses of foraminifera isotopic composition suggest that during MIS 6.5 (180 - 168 ka) the average position of the ITCZ migrated north, marked by an...

Africa's Food Crisis: Conditioning Trends and Global Development Policy
Provedor de dados: 31
Autores: Adesina,   Akinwumi A.
African countries continue to face deepening food crises which have been accentuated by the global food, energy and financial crises. This situation is part of a long term structural problem: decades of under-investments in agricultural sector and poor policies of support for smallholder farmers who form the bulk of the farming population. The inability of these farmers to achieve a supply response when commodity prices were high and market access was less of a problem suggests that there are multiple sets of binding constraints that continue to limit the potential of agricultural growth to reduce food security and poverty on the continent. What the continent needs is a smallholder-based green revolution that can help raise agricultural productivity and...

In Nederland komen steeds meer exotische insecten voor. Vooral soorten die als larve in planten leven hebben een goede kans om geïmporteerd te worden. De larven van boorvliegen leven in stengels, bladeren en vruchten en worden dan ook veel met plantenmateriaal verplaatst. Ze vormen een economisch belangrijke groep omdat sommige soorten schade aanrichten in de fruit- en sierteelt. In dit artikel worden enkele Afrikaanse boorvliegen gemeld die recent in Nederland ingevoerd zijn.

Age and growth of Spanish mackerel (Scomberomorus brasiliensis) off the northeastern coast of Brazil
Provedor de dados: 83
Autores: Nóbrega,Marcelo Francisco de; Lessa,Rosangela Paula.
Age and growth of the Spanish mackerel (Scomberomorus brasiliensis) caught off northeastern Brazil were determined. A total of 831 otoliths were examined - 296 from males (12 - 75 cm FL), 212 from females (11.5 - 72 cm FL) and 323 from specimens of undetermined sex (12.4 - 75 cm FL). There was a high percentage of juveniles in the catches, resulting mainly from the use of gillnets. Marginal increment analysis of the otoliths indicated that the shortest distances from the last ring to the edge occurred from November to May, laying down just one ring annually. One to eight rings were found, with specimen lengths ranging from 11.5 to 75.8 cm. The Schunute model was used to determine what model was best fit the data, demonstrating that the specialized von...

Aflatoxins are known to alter the pathogenesis of many infectious diseases, but such effects have not been evaluated in trypanosome infections. The aim of the present work was to assess the effects of aflatoxin B1 on the pathogenesis of Trypanosoma brucei rhodesiense infection using a murine model. Mice fed on 0.50 mg/kg aflatoxin b. wt. were infected with T. b. rhodesiense and compared to trypanosome infected and uninfected aflatoxin-fed controls. The clinical and pathological changes were determined and the quantitative data statistically analysed using standard methods. The results showed that infected aflatoxin-fed mice had pronounced dyspnoea, significantly (P&lt;0.05) reduced survival, extreme emaciation, pronounced macrocytic normochromic anaemia...

Aggregate stability as affected by short and long-term tillage systems and nutrient sources of a hapludox in southern Brazil
Provedor de dados: 90
Autores: Veiga,Milton da; Reinert,Dalvan José; Reichert,José Miguel.
The ability of a soil to keep its structure under the erosive action of water is usually high in natural conditions and decreases under frequent and intensive cultivation. The effect of five tillage systems (NT = no-till; CP = chisel plowing and one secondary disking; CT = primary and two secondary distings; CTb = CT with crop residue burning; and CTr = CT with removal of crop residues from the field), combined with five nutrient sources (C = control, no nutrient application; MF = mineral fertilizers according to technical recommendations for each crop; PL = 5 Mg ha-1 y-1 fresh matter of poultry litter; CM = 60 m³ ha-1 y-1 slurry cattle manure; and SM = 40 m³ ha-1 y-1 slurry swine manure) on wet-aggregate stability was determined after nine years (four...

Aggregatibacter actinomycetemcomitansarcB influences hydrophobic properties, biofilm formation and adhesion to hydroxyapatite
Provedor de dados: 58
Autores: Longo,PL; Ota-Tsuzuki,C; Nunes,ACR; Fernandes,BL; Mintz,K; Fives-Taylor,P; Mayer,MPA.
The regulation of gene expression in the oral pathogen Aggregatibacter actinomycetemcomitans is still not fully elucidated. ArcAB is a two-component system which allows facultative anaerobic bacteria to sense various respiratory growth conditions and adapt their gene expression accordingly. This study investigated in A. actinomycetemcomitans the role of arcB on the regulation of biofilm formation, adhesion to saliva coated hydroxyapatite (SHA) and the hydrophobic properties of the cell. These phenotypic traits were determined for an A. actinomycetemcomitansarcB deficient type and a wild type strain. Differences in hydrophobic properties were shown at early and late exponential growth phases under microaerobic incubation and at late exponential phase under...

AGGREGATION ISSUES IN THE ESTIMATION OF MALMQUIST PRODUCTIVITY MEASURES
Provedor de dados: 31
Autores: Shaik,   Saleem.
The paper contributes by demonstrating the sensitivity of nonparametric programming productivity measures to the choice of model –time series versus panel models of Malmquist productivity, and to various levels of commodity aggregation compared to the traditional Tornqvist-Theil index approach employing U.S. state-level data from 1960-96.  To illustrate the sensitive of nonparametric programming productivity measures, we compare the implicit shadow shares recovered from the dual values of the Malmquist productivity and total factor productivity methods to the observed shares of the Tornqvist-Theil index for U.S level data from 1948-1994.

Aging as a consequence of misrepair -- A novel theory of aging
Provedor de dados: 17

It is now increasingly realized that the underlying mechanisms which govern aging is a complex interplay of genetic regulation and damage accumulation. Aging as a result of accumulation of &amp;#x2018;faults&amp;#x2019; on cellular and molecular levels, has been proposed in the damage (fault)-accumulation theory by Kirkwood 2006.

AgNO3: a potential regulator of ethylene activity and plant growth modulator
Provedor de dados: 69
Autores: Kumar,Vinod; Parvatam,Giridhar; Ravishankar,Gokare Aswathanarayana.
The aim of this review is to critically analyze the role of silver nitrate (AgNO3) in modulating plant growth and development. In recent years, basic studies on ethylene regulation opened new vistas for applied research in the area of micro-propagation, somatic embryogenesis, in vitro flowering, growth promotion, fruit ripening, and sex expression. Silver nitrate has proved to be a very potent inhibitor of ethylene action and is widely used in plant tissue culture. Few properties of silver nitrate such as easy availability, solubility in water, specificity and stability make it very useful for various applications in exploiting plant growth regulation and morphogenesis in vivo and in vitro. Silver ion mediated responses seem to be involved in polyamines,...

Autores: Simonovic,   Zoran; Simonovic,   Dragoljub; Gligic,   Perica.
Process of transition movements in Republic of Sebia is in progress. Transition movements have not bypassed agrarian sector. Market agriculture should gain significance along this process. On this occasion we would like to emphasis two elements which affect development of Market Agriculture. Those are regionalization and specialization of agriculture. In study about agrarian regions in conditions of transition two charts are given, that pinpoint the essence of natural foundation and market opportunities in transition circumstances. Study of agro-identities starts with introspection of each reagion in respect of its natural values: plain (Vojvodina), hilly ( Sumadija), mountain-hilly (Pester). Therefore, plain region is specialized for production of stable...

Agribusiness Firm Reactions to Regulations: The Case of Investments in Traceability Systems
Provedor de dados: 31
Autores: Heyder,   Matthias; Hollmann-Hespos,   Thorsten; Theuvsen,   Ludwig.
Markets for agricultural and food products are characterized by high information asymmetries since producers, processors and retailers are in most cases much better informed about the quality of their products than consumers (Henson/Traill 1993). Often consumers are only at (prohibitively) high costs or not at all able to control important quality criterions such as food safety, nutritional value or region of origin. Such credence attributes can result in market failure due to a lack of credible information in the market (Akerlof 1970). As a result, attempts to protect consumers against food hazards, product adulteration and deception have gained much relevance in food supply chains (Deimel et al. 2008). Besides the more or less voluntary private...

Agricultura, população e dinâmica macroeconômica de municípios rurais: um estudo em Lagoa dos Três Cantos (RS)
Provedor de dados: 123
Autores: Silva Neto,Benedito; Figueiredo,José Wnilson.
Os municípios com menos de 20.000 habitantes do Rio Grande do Sul abrigam mais de um terço da população total do estado. A partir da hipótese de que a distribuição de renda, a população e a dinâmica da agricultura podem desempenhar um papel importante no desenvolvimento desses municípios, foi elaborado um modelo macroeconômico que permitisse analisar a influência desses fatores sobre economias locais. Simulações efetuadas com esse modelo, aplicado a um pequeno município agrícola do norte do estado (Lagoa dos Três Cantos), indicaram que uma distribuição de renda mais equânime associada a uma diversificação da produção provocariam um aumento significativo da demanda de bens e serviços destinados ao consumo interno, com efeitos benéficos sobre o...

Agricultural Decision Analysis: The Causal Challenge
Provedor de dados: 31
Autores: Parton,   Kevin A.
The paper sets out the agenda for reviewing models of decision making in the context of farmers’ use of seasonal climate forecasting. Such forecasts have been framed in terms of shifts in cumulative distribution functions of yields or gross margins. Typically they have been applied to choices about crop variety, crop type, time of planting or level of fertiliser application. Fundamental questions are: how do farmers conceptualise and make use of the information contained in seasonal climate forecasts? Do our models of decision making represent well the way in which these decisions are made?

Autores: Anderson,   Kym; Croser,   Johanna L.; Sandri,   Damiano; Valenzuela,   Ernesto.
This paper summarizes a new database that sheds light on the impact of trade-related policy developments over the past half century on distortions to agricultural incentives and thus also to consumer prices for food in 75 countries spanning the per capita income spectrum. Price-support policies of advanced economies hurt not only domestic consumers and exporters of other products but also foreign producers and traders of farm products, and they reduce national and global economic welfare. On the other hand, the governments of many developing countries have directly taxed their farmers over the past half-century, both directly (e.g., export taxes) and also indirectly via overvaluing their currency and restricting imports of manufactures. Thus the price...

Agricultural Distortions, Poverty and Inequality in South Africa
Provedor de dados: 31
Autores: Herault,   Nicolas; Thurlow,   James.
South Africa has rapidly reduced trade barriers since the end of Apartheid, yet agricultural production and exports have remained sluggish. Also, poverty and unemployment have risen and become increasingly concentrated in rural areas. This paper examines the extent to which remaining price distortions, both domestic and foreign, are contributing to the underperformance of the agricultural sector vis-à-vis the rest of the economy. We draw on a computable general equilibrium (CGE) and micro-simulation model of South Africa that are linked to the results of a global trade model. This framework is used to examine the effects of eliminating global and domestic price distortions. Model results indicate that South Africa’s agricultural sector currently benefits...

Provedor de dados: 31
Autores: Saunders,   Caroline M.; Kaye-Blake,   William; Campbell,   Rachel; Benge,   J.
Agri-environmental indicators (AEIs) developed by the OECD have been used to assess the environmental performance of the agricultural sector in developed countries. The Agricultural Research Group on Sustainability (ARGOS) in New Zealand has investigated using these AEIs to assess the performance of individual kiwifruit orchards. ARGOS is following panels of orchards to investigate the impacts of organic and conventional management systems on economic, sociological, and environmental dimensions of farming. The environmental monitoring of these orchards has provided data for calculating AEIs. The paper discusses the performance of ARGOS orchards, the impact of management systems, and the implications for future research.

Agricultural Policy: High Commodity and Input Prices
Provedor de dados: 31
Autores: Schmitz,   Andrew; Furtan,   William Hartley; Schmitz,   Troy G.
Because of high commodity prices, beginning in 2006, subsidies to farmers in the United States, the European Union, and Canada have been reduced significantly. However, significant losses have been experienced by the red meat sector, along with escalating food prices. Because of rising input costs, the “farm boom” may not be as great as first thought. Ethanol made from corn and country-of-origin labeling cloud the U.S. policy scene. Higher commodity prices have caused some countries to lower tariff and non-tariff barriers, resulting in freer commodity trade worldwide.

Agricultural Price Distortion and Stabilization: Stylized facts and Hypothesis Tests
Provedor de dados: 31
Autores: Masters,   William A.; Garcia,   Andres F.
This paper describes agricultural policy choices and tests some predictions of political economy theories. It begins with three broad stylized facts: governments tend to tax agriculture in poorer countries, and subsidize it in richer ones, tax both imports and exports more than nontradables, and tax more and subsidize less where there is more land per capita. We test a variety of political-economy explanations, finding results consistent with hypothesized effects of rural and urban constituents’ rational ignorance about small per-person effects, governance institutions’ control of rent-seeking by political leaders, governments’ revenue motive for taxation, and the role of time consistency in policy-making. We also find that larger groups obtain more...

Agricultural Price Distortions, Poverty and Inequality in the Philippines
Provedor de dados: 31
Autores: Cororaton,   Caesar B.; Corong,   Erwin L.; Cockburn,   John.
This paper analyzes the poverty and inequality implications of removing agricultural and non-agricultural price distortions in the domestic market of the Philippines and abroad. Liberalization in the rest of the world is poverty and inequality reducing, whereas full domestic liberalization increases national poverty and inequality. Poverty declines while inequality increases marginally in the combined scenario of both global and domestic agriculture reform. Although the reduction in the national poverty headcount is small in the latter scenario, the poorest of the poor – particularly those living in the rural areas – emerge as “winners”, given their strong reliance on agricultural production and unskilled labor wages.

Agricultural Prices and Income Distribution among Farmers: A Whole-Household, Multi-Country, Multi-Year Analysis
Provedor de dados: 31
Autores: Rios,   Ana R.; Shively,   Gerald E.; Masters,   William A.
Recent studies have emphasized that the poorest farmers are often net buyers of key commodities and therefore harmed by rising prices. We use LSMS data from Tanzania, Vietnam and Guatemala to test the degree of net purchases or sales by income level. We find that poorer farmers may be net buyers of individual crops, but only the poorest are net buyers of all crops. More generally, net sales among poor farmers are low. We conclude that agricultural price changes have a diverse but limited influence on poor farmers’ welfare, because their farm sales tend to be offset by food purchases.

Autores: Yazdani,   Saeed; Vaezi,   L.
Agricultural policies in Iran have aimed at achieving self-sufficiency in food productions through the government various policies. The aim of this paper is to examine the current  level  of  protection  which  may  exist  in   agricultural  sector  in  Iran  and  other  countries. The results indicate that the PSE in Iran is much higher than the OECD and  is close to Japanese and Korean PSE percentage (i.e. 58 and 64 percent). The broadest indicator of support representing the sum of transfers to agricultural producers (PSE), expenditure for general services (GSSE), and direct budgetary transfers to consumers, reached  83  billion  Dollars  per  year  in  2001-2005  which  is  almost  equivalent  to 13.4 percent of Iran’s GDP in this period.

Agricultural production in Greater Sekhukhune: the future for food security in a poverty node of South Africa?
Provedor de dados: 31
Autores: Drimie,   Scott; Germishuyse,   T.; Rademeyer,   L.; Schwabe,   Craig.
This paper argues that within the range of complementary activities necessary to secure the food security of marginalised groups in South Africa in places such as Greater Sekhukhune, the aspect of agricultural production is often neglected. A comprehensive approach to food security should focus on exploiting opportunities around increasing local food availability through production, as well as stimulating food accessibility by, for example, supporting small enterprises through micro-credit, and supporting food utilisation through education. In this way a range of options is created that vulnerable people can adopt to promote their livelihoods beyond survivalist strategies. This paper explores the issue of agricultural production within Greater Sekhukhune...

Agricultural Profits and Farm Household Wealth: A Farm-level Analysis Using Repeated Cross Sections
Provedor de dados: 31
Autores: Blank,   Steven C.; Erickson,   Kenneth W.; Nehring,   Richard F.; Hallahan,   Charles B.
This study examines the relationship between agricultural profits and farm household wealth across locations and farm sizes in U.S. agriculture. A multiperiod household model is used to develop hypotheses for testing. Results indicate that farmland has out-performed nonfarm investments over the past decade. Thus, households may want to keep their farmland to build wealth, even if it requires them to earn off-farm income. The analysis implies that decision will be made based on farm household wealth factors having little to do with agriculture.

Agricultural Protection and Poverty in Indonesia: A General Equilibrium Analysis
Provedor de dados: 31
Autores: Warr,   Peter G.
A general equilibrium modeling approach is used to estimate the effects within Indonesia of unilateral and global trade liberalization, including effects on poverty incidence. It is concluded that global reform of trade policy in all commodities is a significant potential source of poverty reduction for Indonesia. The poor – rural and urban – have a strong interest in global trade policy reform. If Indonesia were to liberalize unilaterally, poverty incidence also would decline but the effect is small. If liberalization is confined to agricultural products, the effects are similar but the declines in poverty incidence within Indonesia are much smaller.

Agricultural Protection Growth in Europe, 1870-1969
Provedor de dados: 31
Autores: Swinnen,   Johan F.M.
Dramatic changes took place in agricultural policies in Europe in the 19th and 20th century. In the 1860s European nations agreed on a series of trade agreements which spread free trade across the continent. In the 1960s European nations concluded an international agreement which spread heavy government intervention and protection against imports across the continent. This paper offers hypotheses as to the causes of these dramatic changes in agricultural protection.

Agricultural Risk Management in the European Union and in the USA
Provedor de dados: 31
Autores: Szekely,   Csaba; Palinkas,   Peter.
Risk management has become increasingly important in virtually all aspects of the economy, including agriculture. Every country that considers agriculture a strategically important economic sector strives for effective risk management in agriculture. In our study American and European Union farmers’ risk management practices were, based on various surveys, compared. In terms of agricultural risk management, major differences between the USA and the EU were evident, and these derive from different farming cultures, differences in historical evolution, and economic philosophy. This study provides an overview regarding the important similarities and dissimilarities.

Agricultural Sustainability and the Introduction of Genetically Modified Organisms (GMOs)
Provedor de dados: 31
Autores: Tisdell,   Clement A.
In order to cater for the predicted growth in global population and aspirations for increased living standards, the world needs to increase substantially its level of agricultural production and sustain agriculture’s increased productivity. New technologies may enable this to occur but they also bring with them increased sustainability problems. There are many complex dimensions to achieving agricultural sustainability such as deciding on what agricultural attributes are worth sustaining and considering what trade-offs in objectives are required. These issues are discussed from a conceptual point of view. It is also shown using economic theory that market-based agriculture limits the opportunity for individual farmers to adopt sustainable agricultural...

Agricultural Trade Flows among Developing Countries: Do Regional Preferential Trade Agreements make a Difference?
Provedor de dados: 31
Autores: Tembo,   Gelson; Jayne,   Thomas S.
Regional integration through trade is recognized as one way to foster economic growth and poverty reduction. This paper uses the gravity model and 11-year panel data (1996-2006) on Southern African Development Community (SADC) member countries to study Zambia’s regional agricultural trade flows and the impact of the SADC Trade Protocol (SADC-TP). Zambia’s volume of trade is significantly related to most of the standard gravity variables. The results indicate that Zambia has been largely trading below potential, especially with respect to exports. There have been improvements in Zambia’s trade flows during the SADC-TP period but only with a few countries. Further improvements will require re-examining protocol implementation and individual countries’...

Agricultural Trade Reform and Poverty in Thailand: A General Equilibrium Analysis
Provedor de dados: 31
Autores: Warr,   Peter G.
A general equilibrium modeling approach is used to estimate the effects within Thailand of unilateral and global trade liberalization, including effects on poverty incidence. It is concluded that across the board trade liberalization is poverty-reducing within Thailand, whether other countries participate in the liberalization or not. This poverty reduction occurs among both farm and non-farm households and this qualitative outcome is not dependent on the particular poverty line used in the analysis. Liberalization in agricultural products alone raises poverty incidence among farm households, while reducing it slightly among non-farm households.

Agriculture biologique et verrouillage des systèmes de connaissances: Conventionalisation des filières agroalimentaire bio

Autores: STASSART, P.M.; JAMAR, D.
La question de la co-existence entre deux systèmes bio, l’un porté par les acteurs historiques, l’autre par les nouveaux acteurs agroindustriels, selon un modèle de bifurcation, est traitée à travers l’hypothèse de conventionalisation. Nous utilisons le cas du système Blanc Bleu Belge et de l’élevage bovin bio belge pour montrer que le problème de la co-existence de ces deux systèmes est à la fois une question empirique et une question théorique. Notre argument est que le concept de « référentiel » (au sens de Jobert et Muller, 1987) est non seulement supérieur d’un point de vue théorique mais qu’il ouvre d’intéressantes perspectives pratiques et ceci pour deux raisons. D’abord parce qu’il permet de comprendre la question et l’enjeu de la co-existence de...

Agriculture for development: New paradigm and options for success
Provedor de dados: 31
Autores: de Janvry,   Alain.
In the classical paradigm of development economics that prevailed in the 1960s, agricultural growth was held to be the key pillar for industrial growth, itself seen to be synonymous with economic development. The paradigm was anchored in telling success stories, from the long history of the “Western Experience” to the then-recent “Asian miracles”. And it was supported by rigorous modeling exercises. But, in spite of success stories, implementation of this paradigm was running into increasing difficulty in the 1970s and early 1980s as policy favored import substitution industrialization with strong anti-agriculture price policy biases. Integrated rural development strategies, designed to meet the broadened development objectives introduced in the 1970s that...

The Cerrado biome, the second largest biome in Neotropical region, consists of a mosaic of different habitat types, ranging from open grasslands to dense woodlands and dry forests. An intensive recent occupation process has transformed it into the most important region for cattle ranching and intensive commodity crops in Brazil. In this study, a macroecological approach was used to evaluate broad-scale spatial patterns of habitat loss in the Brazilian Cerrado, applying a series of spatial autocorrelation and partial regression analyses to understand how the proportion of remaining natural habitats is correlated with socio-economic variables, expressing different dimensions of human occupation and climatic variation. On average, 59% of the area is occupied...

The need for adequate systems to guarantee the quality of food products has become more and more obvious in recent years. As a consequence, not only in Germany but throughout the world, the number of certification schemes has been increasing for nearly a decade. Due to the implementation of these standards in various countries, a considerable number of contingency factors exist that may influence the effectiveness and efficiency of such schemes. These factors include the diverse political, economic and social conditions in the different countries. Numerous studies attribute a decisive role in the successful implementation of management instruments to cultural influences. Cultural conditions may differ considerably from region to region around the world....

Autores: Gutiérrez,Talía Violeta.
En los años sesenta del siglo XX la región pampeana vivía una etapa de modernización y expansión productiva que fue acompañada de una mayor urbanización de la población. Esta situación no significó que desapareciera el interés en definir el lugar de las familias en la explotación agrícola antes bien pensamos que se intensificó y complejizó. El objetivo del presente artículo es analizar el papel atribuido a la familia del productor pequeño o mediano y los roles asignados a sus distintos miembros, en su participación en el desarrollo rural pampeano, desde el Estado y la sociedad civil, a través del análisis de publicaciones periódicas provenientes de esos sectores.

Agrochemical-free, direct-sowing culture of a paddy with non-woven fabric mulch - Timing of puddling and leveling and basal fertilizer application
Provedor de dados: 21
Autores: Hossain, Shaikh Tanveer; Sugimoto, Hideki; Yamashita, Jun; Alcaraz, Joel M.
In direct-sowing rice culture using cloth mulch, puddling and leveling (P &amp; L) is usually done 2 days before the mulching (sowing). However, the mulching is very difficult, due to the muddy condition of the soil. Comparative studies were made to observe the effects of the timing of P &amp; L, that is, P &amp; L 10 days before mulching (P10) vs. P &amp; L 2 days before the mulching (P2), on the operator's physical stress, the rice growth, and grain yield. Basal fertilizer was applied 2 days before the mulching in the P2 treatment (P2-B2), and topdressing was applied at 29 days before heading in all treatments. For the P10 treatment, timing of the basal fertilization was set at 14 (P10-B14) or 3 (P10-B3) days before the mulching.  Results revealed that...

Agro-environmental evaluation of vineyard management using organic farming and integrated plant production systems
Provedor de dados: 21
Autores: FORGET, D.; LACOMBE, J.; DURAND, A.
Organic farming is often considered to be the most environmentally-friendly crop management system, even if integrated production also aims at decreasing the impact of agriculture on the natural environment. In order to establish references for the agro-environmental evaluation of these two production systems in relation to grape growing, INRA carried out an initial study from 2001 to 2004 at the plot scale. This study focused on two grape varieties (Merlot N and Cabernet Sauvignon) in its Couhins vineyard (Graves cru classé), located on two organically-farmed plots and two plots using integrated production, a system based on the implementation of decision rules aimed at limiting the number of pest control treatments. Production means only differed in...

AGROHOLDINGS AND CLUSTERS IN KAZAKHSTAN’S AGRO-FOOD SECTOR
Provedor de dados: 31
Autores: Wandel,   Jurgen.
The paper provides an overview of the institutional arrangements on the micro level that have evolved in the agro-food sector of Kazakhstan in the course of transition. Emphasis is laid on more complex arrangements like "agroholdings" and "clusters", hitherto mostly unknown in the agro-food sectors of established market economies. It is shown that "agroholdings" are concentrated mainly in the northern part of Kazakhstan and to a large extent in the grain sector, while in the south a scattered small scale (individual) farm structure has emerged. Parallel to this market-driven development, the Kazakhstani government tries to promote other institutional arrangements that it deems to be of superior competitiveness, especially agro-food clusters. Refering to...

Agroindústria familiar: um mecanismo de estímulo à especialização das atividades na propriedade rural?
Provedor de dados: 125
Autores: Wesz Junior,Valdemar João.
A agroindústria familiar vem sendo considerada por vários autores como uma importante alternativa de reprodução para a agricultura de base familiar. No entanto, esse processo de produção, que congrega atividades primárias (produção de matéria-prima) e secundárias (industrialização da produção), acaba por criar a preocupação de que a agroindústria, enquanto promotora de geração de renda não-agrícola para os agricultores, pode trazer uma redução ou, em casos mais extremos, a extinção da produção agropecuária nas propriedades em que se encontra a industrialização para venda (agroindústria familiar).

Aid allocation effects on growth and poverty: A CGE framework
Provedor de dados: 31
Autores: Twimukye,   Evarist P.; Nabiddo,   Winnie; Matovu,   John Mary.
It has been argues that increased aid causes Dutch disease as a result of appreciation of the exchange rate which reduces the competitiveness of the country's exports. In this paper, we argue that if the aid is used productively, there are both short and long term gains. Applying a recursive dynamic general equilibrium model on Uganda, we find that while the currency appreciates and some exports decline, the overall impact on growth outweighs the losses in competitiveness. In addition, it aid is used productively, poverty would be substantially reduced as long as the aid increase is sustained.

Aggressive non-Hodgkin's lymphoma (NHL), including primary central nervous system (CNS) lymphoma, lymphoblastic lymphoma and non-endemic Burkitt's lymphoma have been recognized as AIDS-defining cancers in most developed countries. However, HIV/AIDS epidemics appear not to have been associated with higher incidence of lymphomas in Africa. We therefore carried out this study to highlight the significance or otherwise of HIV/AIDS epidemics in the pathogenesis of lymphomas in a population of Nigerians with the disease. Since January 1993 to the present, all patients with haematologic cancers are routinely screened (following appropriate counseling) for HIV infection. Patients with a histological diagnosis of malignant chronic lymphoproliferative diseases...

Autores: Dungan, R.S.; Leytem, A.B.
Endotoxins are derived from gram-negative bacteria and are  a potential respiratory health risk for animals and humans. To  determine the potential for endotoxin transport from a large  open-lot dairy, total airborne endotoxin concentrations were  determined at an upwind location (background) and five  downwind locations on three separate days. The downwind  locations were situated at of the edge of the lot, 200 and 1390  m downwind from the lot, and downwind from a manure  composting area and wastewater holding pond. When the  wind was predominantly from the west, the average endotoxin  concentration at the upwind location was 24 endotoxin units  (EU) m?3, whereas at the edge of the lot on the downwind side  it was 259 EU m?3. At 200 and 1390 m downwind...

Within the EU funded project ORGAP a toolbox was developed for the evaluation of  the European as well as national action plans fror Organics food and farming. Recommendations  and a resource manual for policy makers and stakeholders were  published, based on the analysis of national Organic Action Plans as well as stakeholder  and expert consultation. The analysis showed that several EU member states  have emphasised the need to balance supply-push policies with more market-focused  demand-pull policies. An integrated approach is required through the formulation of  multi-functional Organic Action Plans (OAPs), which also adress the dual roles of  organic farming to provide public goods and satisfy consumer demand.

Autores: Tabaku,   Irma.
According to the World Trade Organization agreements frameworks, individual countries can agree to lower customs tariffs and other trade barriers, in order to open and keep service markets open. In this context, Albania has already concluded free trade agreements with nine countries of the region: Macedonia, Croatia, Bosnia &amp; Herzegovina, Yugoslavia, Moldova, Turkey, Kosovo, Romania, Bulgaria (the last two are EU members now) and by January 2009 the ratification process from the European members’ countries finished. What this means is free exchange of goods and services between these countries by better exploiting their competitive advantages. To better exploit the advantages from free trade at first we need to find out which the Albanian sectors that...

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS
Provedor de dados: 31
Autores: Rosario,   Joe A.
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

ALBERTA’S EXPORT EXPERIENCE UNDER FREE TRADE AGREEMENTS, 1989-2008: TWENTY YEARS OF FREE TRADE
Provedor de dados: 31
Autores: Mirus,   Rolf; Emter,   Nicholas A.
The period of free trade from 1989 to 2008 coincided with a strong expansion of Alberta’s exports. Our review shows that several factors contributed to this success. In addition to favorable trends in energy and commodity prices, the improved access to the US and Mexican markets that resulted from the CUSFTA and NAFTA are shown to be major causes of the positive development of Alberta’s exports. In particular, the significant increase in manufacturing exports can be attributed to the free trade agreements because manufacturing products face higher tariffs in export markets than do raw materials and energy products. Alberta’s manufacturing sector, therefore, emerges as a major beneficiary of freer trade. As a result, Alberta’s economy has become more...

Las encuestas de victimización se han convertido en uno de los instrumentos más utilizados en el diagnóstico de la inseguridad ciudadana, por cuanto permite conocer en mejor medida la “cifra negra” producida por los bajos niveles de denuncia de hechos delictivos en países como Ecuador. Sin embargo, como todo instrumento de diagnóstico, no son neutrales ni objetivos en su totalidad ya que parten de una serie de supuestos sobre la comprensión de la realidad. Como señalan los especialistas en el tema, la forma que adopta el fenómeno del delito a través de este instrumento depende de la manera en que esté diseñado el cuestionario de la encuesta.

Alcohol dehydrogenase activities and ethanol tolerance in Anastrepha (Diptera, Tephritidae) fruit-fly species and their hybrids
Provedor de dados: 74
Autores: Carvalho,Eneas; Solferini,Vera Nisaka; Matioli,Sergio Russo.
The ADH (alcohol dehydrogenase) system is one of the earliest known models of molecular evolution, and is still the most studied in Drosophila. Herein, we studied this model in the genus Anastrepha (Diptera, Tephritidae). Due to the remarkable advantages it presents, it is possible to cross species with different Adh genotypes and with different phenotype traits related to ethanol tolerance. The two species studied here each have a different number of Adh gene copies, whereby crosses generate polymorphisms in gene number and in composition of the genetic background. We measured certain traits related to ethanol metabolism and tolerance. ADH specific enzyme activity presented gene by environment interactions, and the larval protein content showed an...

ALERT:  FARMERS NEED TO SIGN UP FOR ACRE!
Provedor de dados: 31
Autores: Hilker,   James H.; Betz,   Roger; Black,   J. Roy.
Corn, soybean and wheat producers are facing serious financial challenges. And it is even worse for livestock producers, most of who are also crop producers and are therefore eligible for ACRE.  Crops are behind in maturity, some areas of the state need rain, product prices have fallen substantially, and USDA Counter Cyclical payments do not start until $2.35 on corn, $5.36 soybeans and $3.40 on wheat. Chances of prices that low are around 10-15%, but at that point ACRE payments would be much, much bigger.  Many producers do not understand ACRE and the benefits available; most of the reasons given for not participating are invalid.

Alfred Russel Wallace and the Darwinian Species Concept: His Paper on the Swallowtail Butterflies (Papilionidae) of 1865
Provedor de dados: 72
Autores: Mallet,James.
Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most signifcant papers. The paper used butterfies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the description of some 20 new species. Wallace argued that the Papilionidae were the most advanced butterfies, against some of his colleagues such as Bates and Trimen who had claimed that the Nymphalidae were more advanced because of their possession of vestigial forelegs. In a very important section, Wallace laid out what is perhaps the clearest Darwinist defnition of the differences between species, geographic subspecies, and local ‘varieties.’ He also discussed...

Este trabalho objetivou analisar a riqueza e a abundância de algas perifíticas nos rios do Corvo e Guairacá, tributários do reservatório de Rosana, quando da instalação de tanques-rede. Acreditava-se que o ponto logo à frente dos tanques-rede apresentaria menor riqueza e abundância de algas e que o reservatório influenciaria as estações a jusante dos tanques. Para isso, coletas foram realizadas a montante, em frente e a jusante da instalação de tanques-rede. Independentemente do ambiente, a estação que apresentou maior riqueza foi 1.000 m a montante. Diminuição na riqueza foi verificada nas estações 500 m a montante e 500 m a jusante. Quanto à densidade, em frente aos tanques, observou-se maior abundância, seguida pela estação a 1.000 m a jusante. Já, nas...

A cultura algodoeira é uma atividade agrícola de reconhecida importância socioeconômica, principalmente para o Nordeste brasileiro, onde ela é executada por pequenos agricultores, que representam uma maioria na região, constituindo-se numa importante fonte de geração de emprego e de renda no campo. É uma atividade secular, altamente importante para a agricultura familiar, uma vez que, pelas condições climáticas da região, o algodão é a principal opção fitotécnica, em razão de sua tolerância à seca e pelo fato de possuir mercado potencialmente garantido, já que o Nordeste é o segundo polo de consumo industrial de pluma do Brasil, com quase 300 mil toneladas de pluma por ano. Portanto, os agricultores têm tradição no que diz respeito à cultura. Além disso,...

Alien species alert: Crassostrea gigas (Pacific oyster)
Provedor de dados: 5
Autores: Miossec, Laurence; Le Deuff, Rose-marie; Goulletquer, Philippe.
The Pacific oyster (Crassostrea gigas, Thunberg, 1793) is one of 20 species in the genus Crassostrea. Although native to the Japan/Korea region, C. gigas is a hardy species that has been introduced to a number of countries worldwide, including the US, Canada, the UK, France, Korea, China, New Zealand, Australia, South Africa, and South America, mainly for aquaculture purposes (Mann et al., 1991; Orensanz et al., 2002). As a result, C. gigas has become the leading species in world shellfish culture, with an estimated production of 4.6 million t in 2006 (FAO, 2008). Because C. gigas does not require additional food to sustain its growth, this species is relatively inexpensive and easy to produce. Its capacity to adapt to various environmental conditions and...

Allelopathic effects of Eucalyptus citriodora on amaryllis and associated grassy weed
Provedor de dados: 87
Autores: El-Rokiek,K.G; Eid,R.A.
A Petri dish assay was carried out for screening different concentrations of aqueous extracts of fresh and dry leaves of Eucalyptus citriodora on germination and seedling growth of wild oat weed (Avena fatua). Seed germination, root and shoot length of wild oat exhibited different degrees of inhibition according to the concentration of the aqueous extract. Maximum inhibitions of germination percentage, root and shoot length were recorded when using 25% fresh leaf extract. Based on this preliminary work (Petri dish assay), studies were conducted under greenhouse conditions at the National Research Center, Egypt, in the two winter seasons of 2006/2007 and 2007/2008 to evaluate the effects of foliar and soil treatments of aqueous extracts of Eucalyptus...

Environmental degradation caused by the excessive use of pesticides has motivated studies aimed at the discovery of new formulations for pest control. The bioassays carried out under laboratory conditions for the present study involved the germination and seedling growth of Lactuca sativa cv. Grand Rapids and Allium cepa cv. Baia Periforme treated with lecanoric acid or one of seven esters obtained from the alcoholysis of the acid. Each substance was tested at concentrations of 10-3, 10-5, 10-7 M, and 10-9 M. The results revealed that, except for lecanoric acid and methyl orsellinate, all other compounds exhibited significant differences in their action when compared with the controls. Also, A. cepa was more sensitive to the compounds assayed, at the...

Allergies, Asthma, and Eczema: Response to Disturbance of the Microbiota of the Newborn Gut
Provedor de dados: 17
Autores: Debra L. Wohl; William J. Curry.
*Background/Question/Methods*&amp;#xd;&amp;#xa;The birth of a child may include routine use of antibiotics or a delivery by cesarean section.  We applaud these medical advances for their direct benefits.  However, birthing practices have been shown to disrupt the colonization of the microbial gut in newborns, which may have long term consequences on the development of a child&amp;#x2019;s immune system resulting in atopies (i.e., asthma, allergies, and eczema).  Animal models and other research have been used to demonstrate that not only the presence, but also the community composition of the gut microbiota, is essential for normal immune development.  Furthermore, it has been established that there are differences in the intestinal microbiota of children...

Allergiezusammenhänge im Überblick: Milchfettqualität als  schützende Maßnahme gegen Allergien
Provedor de dados: 21
Autores: Baars, Prof Dr Ton; Jahreis, Prof Dr Gerhard.
Allergy in human populations is increasing due to modern lifestyle. Farm children and  children with an anthroposophic lifestyle showed less allergic symptoms. This article  describes the modern insights about nowadays nutrition and lifestyle factors impacting  on the development of allergies and the research done in the 1920s about the health  status of indigenous people and their eating behaviour. Many epidemiological studies  mention the quality of farm milk, raw milk and milk fat as important factors to reduce  the risk of allergies. It is explained why and how a high-quality milk fat in terms of  conjugated linolenic acid and omega-3 long-chain fatty acids are influencing the cell  physiology. These new insights will affect future strategies of...

Allocation of Advertising and Research Dollars In the Florida Orange-Juice Industry
Provedor de dados: 31
Autores: Brown,   Mark G.
In this study, an OJ model was developed to examine the optimal advertising-research mix to maximize Florida grower revenue net of the costs of these activities.  The model is based on assumed coefficients reflecting the impacts of prices, advertising and research.  The effects of prices on demand and supply, as well as the effect of advertising on demand, were set based on findings of prior studies.  The effect of research on supply is less certain, and a range of research effects was considered.  A range of advertising effects was also considered given the study’s focus.   The model solutions for the various advertising and research assumptions considered indicate that optimal advertising expenditures are significant

Allocation of Authority in Agricultural Production Contracts
Provedor de dados: 31
Autores: Cakir,   Metin; Balagtas,   Joseph Valdes; Wu,   Steven Y.
The objective of this paper is to develop a model that explains the involvement of first level handlers in farm level decisions. In particular, the research attempts to explain observed differences among levels of farmer's autonomy in production contracts of different agricultural commodities. We show that the trade off that a contractor faces for holding the decision rights for controlling production inputs varies for different production environments. In particular, the contractor prefers controlling inputs in production of commodities that have relatively uniform production environments, whereas it is more efficient to delegate the control to the producer for commodities that have diverse production environments.

Allozyme comparison of two populations of Rineloricaria (Siluriformes, Loricariidae) from the Ivaí River, upper Paraná River basin, Brazil
Provedor de dados: 74
Autores: Limeira,Daniel M.; Renesto,Erasmo; Zawadzki,Cláudio H.
Two allopatric morphotypes of the genus Rinelocaria were compared through the allozyme electrophoresis technique: one morphotype, R. pentamaculata, from the Keller River in the middle stretch of the Ivaí River basin and the other, R. aff. pentamaculata, from the São João River in the upper portion of the Ivaí River basin. The morphotype from the São João River was collected upstream from the São João waterfall, which is about 80 m deep. Twelve enzymatic systems (AAT, ADH, EST, GCDH, G3PDH, GPI, IDH, LDH, MDH, ME, PGM and SOD) were analyzed, which allowed to score 22 loci. Only loci Aat-2, Est-3 and Mdh-C showed polymorphism. The two samples differed in allele frequencies at the three polymorphic loci. The average expected heterozygosity for all loci was...

Provedor de dados: 80
Autores: Mesquita-Ferrari,RA; Moraes,CK de; Micocci,KC; Selistre-de-Araújo,HS.
ALT-C, an ECD motif (glutamic acid, cysteine, aspartic acid) disintegrin from Bothrops alternatus snake venom, induces α2β1 integrin-mediated signaling and neutrophil chemotaxis. In vitro, in human umbilical vein endothelial cells (HUVEC), ALT-C induces cell proliferation, thus showing an interesting potential for tissue regeneration studies. This work aimed to evaluate the influence of ALT-C in myoblast viability and differentiation. Myoblasts were obtained from hind limb muscles of 3 to 4-day old Wistar rats. The cells were incubated with ALT-C at different concentrations and incubation periods were followed by total RNA isolation. cDNA synthesis and real time polymerase chain reaction (PCR) were performed with primers of myoD as well as of both (slow...

Autores: ALATZAS,ANASTASIOS; FOUNDOULI,ATHINA.
Although several histone variants have been studied in both animal and plant organisms, little is known about their distribution during processes that involve alterations in chromatin function, such as differentiation, dedifferentiation and hormone treatment. In this study we evaluated the ratio of each histone variant in each of the four core histone classes in the three developmental zones of maize (Zea mays L.) root and in callus cultures derived from them, in order to define possible alterations either during plant cell differentiation or dedifferentiation. We also evaluated core histone variant ratios in the developmental zones of roots treated with auxin and gibberellin in order to examine the effects of exogenously applied plant hormones to histone...

The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasing the movement of people, materials, and energy into and within the basin.  We argue that this expansion of ecological commerce requires new science, monitoring, and management strategies focused on large rivers and suggest that traditional geopolitical and economic boundaries for environmental decision making be appropriately revised. Effective mitigation of the...

Altered expression of the caffeine synthase gene in a naturally caffeine-free mutant of Coffea arabica
Provedor de dados: 74
Autores: Maluf,Mirian Perez; Silva,Carla Cristina da; Oliveira,Michelle de Paula Abreu de; Tavares,Aline Gomes; Silvarolla,Maria Bernadete; Guerreiro Filho,Oliveiro.
In this work, we studied the biosynthesis of caffeine by examining the expression of genes involved in this biosynthetic pathway in coffee fruits containing normal or low levels of this substance. The amplification of gene-specific transcripts during fruit development revealed that low-caffeine fruits had a lower expression of the theobromine synthase and caffeine synthase genes and also contained an extra transcript of the caffeine synthase gene. This extra transcript contained only part of exon 1 and all of exon 3. The sequence of the mutant caffeine synthase gene revealed the substitution of isoleucine for valine in the enzyme active site that probably interfered with enzymatic activity. These findings indicate that the absence of caffeine in these...

Autores: KNUPP, A. M.
No procedimento convencional para quantificação do carbono da biomassa microbiana, que vem sendo adotado no laboratório de Biologia do Solo, o teor de carbono microbiano das amostras de solo é quantificado a partir de sua digestão com uma solução ácida de dicromato de potássio. Essa solução é tóxica, além de gerar um resíduo ácido contendo um metal pesado (cromo), após o processo de digestão. Uma adaptação para esse método foi testada visando à redução do volume da solução ácida de dicromato de potássio utilizada, o que acarretaria menor risco na manipulação e menor passivo ambiental.

Alternativas para o manejo da mosca-das-frutas.
Provedor de dados: 14
Autores: KOVALESKI, A.; RIBEIRO, L. G.
Ao longo de vários anos de cultivo de maçã e outras fruteiras temperadas a mosca-das-frutas tem sido considerada como a mais importante praga e uma das mais difíceis de serem controladas. O grande número de hospedeiros alternativos distribuídos principalmente em áreas nativas oferecendo condições para a multiplicação da praga e a pouca disponibilidade de ferramentas para o seu controle colocam a mosca-das-frutas nesse patamar de importância econômica. Na região produtora de maçã dois hospedeiros são muito importantes: cereja-do-riogrande, guabiroba e goiaba serrana. A cereja-do-riogrande é a primeira fruta da primavera e a produção depende muito das condições climáticas da primavera. A guabiroba é uma fruta que começa a amadurece no início de dezembro e...

ALTERNATIVE FUTURES OF RURAL AREAS IN THE EU: A COMPARATIVE ANALYSIS OF SCENARIO STUDIES
Provedor de dados: 31
Autores: Jansson,   Kristina M.; Terluin,   Ida J.
What does rural Europe look like in 2030? Is agriculture still the main land user? In recent years, studies such as ESPON, Eururalis, SCENAR2020, SENSOR, SEAMLESS and PRELUDE have tried to address these questions. These studies resulted in a number of alternative futures of rural areas in the EU. In this paper a comparative analysis of these scenario studies is made in order to explore differences and similarities in the scenarios and alternative futures of rural areas in the EU. For this purpose, we designed a scheme for assessing the properties of the various scenarios and a scheme for a systematic description of the rural futures according to the scenarios. It appears that most scenario studies use a baseline scenario and a set of alternative scenarios...

Alternative Housing Development Strategies in Georgia's Coastal Marshlands
Provedor de dados: 31
Autores: Kriesel,   Warren; Mullen,   Jeffrey D.
Coastal Georgia continues to experience extremely high population growth rates. People are attracted by coastal amenities, including pleasant views of the saltwater marshes. The real estate market has responded to population growth with a pattern of development that exhibits varying degrees of compatibility with the nearby marshland ecosystem. Among community leaders there is a need for information on development alternatives. Information has been generated from a hedonic price analysis that contains proximity to amenities and development design variables. We conclude that real estate developers have, under certain circumstances, an economic incentive to incorporate more open space in their design of residential subdivisions in marshland environments.

Alternative Model Selection Using Forecast Error Variance Decompositions in Wholesale Chicken Markets
Provedor de dados: 31
Autores: McKenzie,   Andrew M.; Goodwin,   Harold L., Jr.; Carreira,   Rita I.
Although Vector Autoregressive models are commonly used to forecast prices, specification of these models remains an issue. Questions that arise include choice of variables and lag length. This article examines the use of Forecast Error Variance Decompositions to guide the econometrician’s model specification. Forecasting performance of Variance Autoregressive models, generated from Forecast Error Variance Decompositions, is analyzed within wholesale chicken markets. Results show that the Forecast Error Variance Decomposition approach has the potential to provide superior model selections to traditional Granger Causality tests.

There were tested water extracts from Syringa vulgaris and Pyrethrum parthenium. They did not prove signincant differences ofdecrease of the air attack ofColorado potato beetle (Leptinotarsa decemlineata), the activity ofeggs -laying and the occurrence oflarvae in comparison to the control. Interesting trends oflower-eggs lying and a lower larvae occurrence were discovered. The liquid spray against the late blight (Phytophthora infestans) did not signincantly decrease neither occurrence oflate blight or the yield.  The production of the bio-potatoes is only 0,2% of all potatoes production in the Czech Republic. The aim of this experiment was to try alternative methods of regulation of Colorado potato beetle and late blight (the biggest harmful! organisms...

Alternativen zur betäubungslosen Ferkelkastration - Stand der Forschung zur Verbraucherakzeptanz der Alternativen
Provedor de dados: 21
Autores: Heid, Astrid; Hamm, Ulrich.
In Europa werden fast alle männlichen Ferkel routinemäßig kastriert, um die Entstehung von Ebergeruch zu verhindern. In der Regel erfolgt dieser Eingriff ohne Betäubung. Aktuell findet eine Diskussion über die Tierschutzrelevanz der betäubungslosen Ferkelkastration statt und ein Verbot dieser Praxis wird angestrebt. Daher müssen Alternativen zur betäubungslosen Kastration gefunden werden.   Ein wichtiger Faktor bei der Bewertung der Umsetzbarkeit der diskutierten Alternativen zur betäubungslosen Ferkelkastration ist die Bereitschaft der Verbraucher das so produzierte Fleisch auch zu kaufen. Der Beitrag gibt einen Überblick über den aktuellen Stand der Forschung zur Verbraucherakzeptanz der Alternativen zur betäubungslosen Ferkelkastration.

Autores: Tomasek, Jaroslav; Dvorak, Petr.
Cílem pokusu bylo zvýšit vitalitu rostlin a produkci kvalitních hlíz. Pokus byl zaměřen na regulaci mandelinky bramborové (Leptinotarsa decemlineata) a plísně bramboru (Phytophthora infestans), což jsou faktory působící největší obtíže při ekologickém pěstování brambor. Přípravek Neem-Azal vykazoval trend nižšího kladení larev mandelinky. Kombinace mědnatého fungicidu s přípravkem PRB-EBV a vermikompostem snižovaly napadení natě plísní bramboru. Výnos byl statisticky nejnižší při použití sítě (jako mechanické zábrany). Nebyly zjištěny významné rozdíly ve výnosu při použití přípravků posilujících vitalitu rostlin.

Ambiguous jointness and multifunctionality
Provedor de dados: 31
Autores: Romstad,   Eirik.
Many previous analyses of multifunctionality in agriculture claim there is positive jointness between the production commodities and nonmarket goods and services. Those analyses have not treated acreage as an endogenous variable. This leads to several errors in terms of the analysis of policy impacts, and hence also the policy advice. The main contribution of this paper is the development of an analytical framework where acreage is endogenously determined.  This framework is then used to demonstrate that any policy that influences resource allocation also affects agricultural commodity production. Hence, there is no such thing as a fully decoupled support. The impacts on commodity markets from direct payments to environmental goods and services are,...

Amenity benefits and public policy: An application to the Georgia Pecan Industry
Provedor de dados: 31
Autores: Sande,   Doris N.; Mullen,   Jeffrey D.; Nzaku,   Kilungu.
Most agricultural production results in both marketable and non-marketable products. Most policy decisions however, tend to be made based only on the market value, which ignores the non-marketable value or amenity benefits. One type of amenity benefits is farmland amenities which are attributes of farmland that are uniquely provided by actively farmed land. Examples include the scenic beauty of rolling pasture, orchards and the cultural value of farming as a way of life. Farmland also produces non-farm amenities, such as open space, wildlife habitats, and groundwater recharge. Most amenity benefits are classified as public goods in that they are non-excludable and non-rival in terms of use. Thus, most amenities do not have a market value associated with...

American marsupials chromosomes: why study them?
Provedor de dados: 74
Autores: Svartman,Marta.
Marsupials, one of the three main groups of mammals, are only found in Australia and in the American continent. Studies performed in Australian marsupials have demonstrated the great potential provided by the group for the understanding of basic genetic mechanisms and chromosome evolution in mammals. Genetic studies in American marsupials are relatively scarce and cytogenetic data of most species are restricted to karyotype descriptions, usually without banding patterns. Nevertheless, the first marsupial genome sequenced was that of Monodelphis domestica, a South American species. The knowledge about mammalian genome evolution and function that resulted from studies on M. domestica is in sharp contrast with the lack of genetic data on most American...

Autores: Kenkel,   Philip L.; Holcomb,   Rodney B.
The American Native Beef project involved a failed attempt to establish cow and bull slaughter operation in Southeast Oklahoma. The effort was initially organized as a new generation cooperative and raised over US$2.5M from area producers who retained their funds in escrow for over 5 years despite numerous opportunities to withdraw their investment. The business model was restructured several times to attract equity capital from outside investors. The case provides insights into the linkages between business strategy and business structure. It also raises the question as to whether the project could have been successful under the original business model.

Esta análise avalia a acidez (pH), a disponibilidade de nutrientes (P, K, Ca e Mg) ou a presença de alumínio (Al) no solo, em nível tóxico para as culturas, de forma rápida e a baixo custo. A primeira e mais crítica etapa da análise química refere-se ao processo de amostragem do solo. Alguns passos devem ser observados nessa fase, pois um erro na amostragem poderá comprometer as etapas seguintes na definição das quantidades de calcário e fertilizantes a serem aplicadas na cultura. A época de amostragem varia com o manejo do solo, a cultura e outros fatores. Para culturas anuais, recomenda-se que a...

Visou-se, neste trabalho, avaliar a variabilidade de características químicas do solo, definir o número de amostras simples para formar uma amostra composta e avaliar se a média aritmética das amostras simples é igual ao resultado da análise química da amostra composta. Realizaram-se três séries de amostragens constituídas de 36 amostras simples por série, em um Latossolo Amarelo. Os locais de retirada das amostras da primeira série se distanciaram 15 m um do outro, os da segunda série, 2,5 m, e os da terceira série, 0,42 m. Com as amostras de solo da primeira série, foram formuladas amostras compostas mediante a mistura homogênea de 4, 8, 14, 20, 28 e 36 amostras simples, utilizando-se três repetições. A variabilidade das características químicas do solo...

A necessidade de ampliação da densidade de coleta em escala nacional, tanto para subsidiar a identificação de áreas prioritárias para conservação como para ampliar o conhecimento sobre a biota do país, tem sido enfatizada em diversas análises recentes sobre a biodiversidade brasileira. No caso das plantas, a densidade de coleta em escala nacional (0,44 exsicatas/km²) está bem abaixo do considerado adequado para um conhecimento completo da flora (3 exsicatas/km²) ou mesmo para a avaliação da riqueza de uma determinada região (1 exsicata/km²). Análises recentes têm revelado que mesmo nas regiões Sul e Sudeste, dotadas de mais infra-estrutura e maior número de botânicos, a densidade de coletas é insatisfatória. No estado de São Paulo algumas regiões têm sido...

An agro-economic model to analyse climate change impacts on farmers' income
Provedor de dados: 31
Autores: Jiang,   Qiang.
The increasing interests in climate change heighten the need for an agro-economic model to analyse climate change impacts on farmers’ incomes. Many researchers have turned to crop yield response models to estimate farmers’ yield and income loss. A classic method used by economists to establish yield response models is to build up the statistic relationship between historical yield changes and climate change through regression models. However, without comprehensive experimental data from each region such as crop yields response to CO2 concentration, these crop-yield response models may provide misleading predications. An alternative approach is the use of crop biophysical simulation models.   Based one biophysical model Agricultural production systems...

An Analysis of Bundle Pricing in Horizontal and Vertical Markets: The Case of the U.S. Cottonseed Market
Provedor de dados: 31
Autores: Shi,   Guanming; Stiegert,   Kyle W.; Chavas,   Jean-Paul.
In this paper, we investigate substitution/complementarity relationships among products sold with different bundled characteristics and under different vertical arrangements. Our conceptual model demonstrates the interactive price impacts emanating from product differentiation, market concentration and market size. The model is applied to the U.S. cottonseed market using transaction level data from 2002 to 2007. This market has been impacted structurally in numerous ways due to the advances and the rapid adoption of seeds with differing bundles of biotechnology traits and vertical penetration emanating from the biotechnology seed industry. Several interesting findings are reported. The econometric investigation finds evidence of sub-additive pricing in the...

An Analysis of Demand Elasticities for Fluid Milk Products in the U.S.
Provedor de dados: 31
Autores: Davis,   Christopher G.; Blayney,   Donald P.; Cooper,   Joseph C.; Yen,   Steven T.
This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products.  Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities.  To derive the demand elasticities, a censored translog demand system is used.  The results reveal that price and income are the main determinants of demand for fluid milk products...

After outlining environmental problems regarding food-economy2 companies and clarifying the concept of environmental behaviour, I will present the results of my questionnaire survey which focussed on food-economy companies in the Northern Great Plain region (Region). Based on solid data, the survey was designed to evaluate the companies’ commitment toward environmental protection. Sometimes the observed value systems conformed with the results of other national surveys (e.g. environmental behaviour factors; environmental protection’s rank among business aims), but at times I observed that in certain areas they truly lagged behind: for example, this held true for . the number of companies with a certified environmental-management system (EMS) and also for...

Autores: Özbilge, Zeynep.
This article gives information about the current situation of Turkish organic agriculture, especially by comparing the official recognition for organic farming in the European Union with that of Turkey and summarizes the existing constraints. The analysis indicates that the further development of Turkish organic agriculture depends upon the development of the domestic organic market and Turkey has to fulfil a number of conditions to provide it. It is needed that the Turkish state both encourages organic production for the domestic market and supports organic agriculture by all means.

Autores: Shi,   Guanming; Stiegert,   Kyle W.; Chavas,   Jean-Paul.
The purpose of the research in this paper is to investigate the impact of differentiated vertical strategies by agricultural biotechnology firms in the U.S. cottonseed market. The model advances the measurement of industry concentration to consider substitution/complementarity relationships among differentiated products delivered under different vertical structures. We find evidence of sub-additive pricing in the stacking of bundled biotech traits. Prices paid by farmers for cottonseed sold under vertical integration are found to be higher than under licensing. The model is flexible and allows for evaluation of the effects of changing market structures. The parameters on traditional measures of concentration indicate that higher concentration leads to...

Autores: Boland,   Michael A.; Crespi,   John M.; Oswald,   Dustin.
Our objective is to identify the determinants for success among USDA’s Value- Added Producer Grants (VAPG) program recipients. Business development has become an important program in departments of agricultural economics. Market share was found to be an important determinant of VAPG success. Size variables including greater sales and increased grant dollars, as well as a lower number of producers, were also determinants of business success. Departments of agricultural economics are likely best able to assist VAPG recipients by providing information on price discovery, explaining their relationship to potential plant location, and providing education on best management practices to help producers avoid costly mistakes.

The liberalization and restructuring of the seed sector in eastern and southern Africa (ESA) during the past two decades have witnessed a proliferation of private seed companies in the maize seed industry (Hassan et al., 2001; Lemonius, 2005). Although the total number of registered maize seed companies increased from 8 and 11, respectively, in 1997 to 40 each, the quantities of seed marketed barely doubled, increasing from 23,000 and 27,000 tons to 53,000 and 51,000 tons, respectively; an indication that the reforms are insufficient in ensuring efficient functioning of the sector in the two regions. A study involving 117 seed providers, representing 92 percent of all registered maize seed companies in ESA in 2007 identified bottlenecks that have...

An Analysis of the Pricing of Traits in the U.S. Corn Seed Market
Provedor de dados: 31
Autores: Shi,   Guanming; Chavas,   Jean-Paul; Stiegert,   Kyle W.
This paper investigates the pricing of patented traits in the U.S. hybrid corn seed market under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschman index (GHHI) capturing cross-market effects of imperfect competition on bundle pricing. The GHHI model is applied to pricing of conventional and patented biotech seeds in the US from 2000-2007. One major finding is that standard component pricing in biotech traits is soundly rejected in favor of subadditive bundle pricing. The econometric estimates show how changes in market structures (as measured by both own- and cross-Herfindahl...

An analysis of the spatial and temporal patterns of greenhouse gas emissions by agriculture in Western Australia and the opportunities for agroforestry offsets
Provedor de dados: 31
Autores: Kingwell,   Ross S.; Harris-Adams,   Keely.
If agriculture is included in an Australian emissions trading scheme then it may face from 2015 at the earliest, a price for its greenhouse gas emissions; and thereby have incentives to offset and lessen its emissions. Yet because there is currently little understanding of the spatial pattern of emissions in agricultural regions of Australia, the extent of the challenge the sector faces in reducing its emissions is not fully recognised. To improve our understanding, this study uses the National Greenhouse Accounts methodology to estimate the spatial and temporal patterns of agricultural emissions since 1990 in the key agricultural region in Australia’s southwest. This region generates almost 40 percent of the nation’s winter crop production and supports...

An application of Data Envelopment Analysis (DEA) to Evaluate Economic Efficiency of Poultry Farms in Bangladesh
Provedor de dados: 31
Autores: Begum,   Ismat Ara; Buysse,   Jeroen; Alam,   Mohammad Jahangir; Van Huylenbroeck,   Guido.
This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the...

Autores: Fabien Alibart; Stephane Pleutin; David Guerin; Christian Gamrat; Dominique Vuillaume.
Molecule-based devices are envisioned to complement silicon devices by providing new functions or already existing functions at a simpler process level and at a lower cost by virtue of their self-organization capabilities, moreover, they are not bound to von Neuman architecture and this may open the way to other architectural paradigms. Here we demonstrate a device made of conjugated molecules and metal nanoparticles (NPs) which behaves as a spiking synapse suitable for integration in neural network architectures. We demonstrate that this device exhibits the main behavior of a biological synapse. These results open the way to rate coding utilization of the NOMFET in perceptron and Hopfield networks. We can also envision the NOMFET as a building block of...

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

An assessment of farmer’s risk exposures and policy impacts on farmer’s risk management strategy
Provedor de dados: 31
Autores: Anton,   Jesus; Kimura,   Shingo.
This paper describes farmer’s exposures to risks at the individual farm level and develops a model representing the decisions of an individual risk averse farmer facing variability in both prices and yields. A set of stylised risk market instruments is represented. The model is calibrated using farm level data from Germany. Monte-Carlo simulations of the random variables are run, and the corresponding optimal responses are obtained. The main focus of this paper is the interactions between government payments and the farmers’ use of risk market instruments in terms of the potential crowding out of such instruments and impacts on farm return and welfare. Unlike other studies this paper models farming response to payments in terms of production and the use of...

An Economic Analysis of Modern Rice Production Technology and its Adoption Behaviour in Tamil Nadu
Provedor de dados: 31
Autores: Devi,   K. Sita; Ponnarasi,   T.
Rice is the staple food in Tamil Nadu and is grown in an area of 2.6 Mha with a production of 8.19 Mt and productivity of 3.2 t/ha. In the context of high water demand by rice farmers, any strategy that would produce higher rice yield with less water is the need of the day. One such system is “System of Rice Intensification” (SRI), which was developed by Fr. Henri de Laulanie in Madagascar in 1980. The general objective of the study is to find the economics and the farmer’s adoption behaviour of the system of rice intensification. The study has revealed that the per hectare cost of cultivation is about 10 per cent lower in SRI than the conventional method. The logit framework has indicated that age, farm size, income of the farm, number of earners in the...

An Economic Evaluation of the Hass Avocado Promotion Order’s First Five Years
Provedor de dados: 31
Autores: Carman,   Hoy F.; Li,   Lan; Sexton,   Richard J.
The U.S. avocado industry has evolved from an emphasis on seasonal domestic production of a mix of avocado varieties to year-round availability of domestic and imported Hass avocados. California avocado producers, who account for approximately 90% of U.S. avocado production and essentially all U.S. Hass avocado production, have funded promotional programs for avocados since 1961. With few imports of avocados prior to the early 1990s, the benefits from these demand-enhancing programs flowed directly to California producers.   Imports of avocados into the United States have increased steadily since then, resulting in a free-rider problem that led ultimately to creation of the Hass Avocado Promotion, Research, and Information Act of 2000. This act established...

An Economic Framework for Forecasting Land-Use and Ecosystem Change
Provedor de dados: 31
Autores: Lewis,   David J.
This paper develops a joint econometric-simulation framework to forecast detailed empirical distributions of the spatial pattern of land-use and ecosystem change. In-sample and out-of-sample forecasting tests are used to examine the performance of the parcel-scale econometric and simulation models, and the importance of multiple forecasting challenges is assessed. The econometric-simulation method is integrated with an ecological model to generate forecasts of the probability of localized extinctions of an amphibian species. The paper demonstrates the potential of integrating economic and ecological models to generate ecological forecasts in the presence of alternative market conditions and land-use policy constraints.

An Economy-wide Analysis of Impacts on Taiwan of Reducing Tariff Escalation on Agriculture-Related Products in WTO Doha Round Negotiations
Provedor de dados: 31
Autores: Lee,   Huey-Lin; Chang,   Ching-Cheng; Weng,   Yung-Ho; Hsu,   Sheng-Ming; Hsu,   Shih-Hsun.
Tariff escalation becomes one of the major issues in the new Doha Round negotiation because it is viewed as a stumbling block to the industrialization development for the developing countries.  When tariffs on products escalate with the stage of processing, the effective rate of protection, or the tariff expressed as fractions of value-added after deducting intermediate inputs from product value, also increases. Thus, tariff escalation potentially signals high rates of protection for value-added or processed products, and can inhibit international trade in these goods.  The major purpose of this study is to examine the degrees of tariff escalations in Taiwan’s agriculture-related commodities and the economic consequences to reduce them.  A simplified...

An efficient and rapid DNA minipreparation procedure suitable for PCR/SSR and RAPD analyses in tropical forest tree species
Provedor de dados: 52
Autores: Alzate-Marin,Ana Lilia; Guidugli,Marcela Corbo; Soriani,Hilda Hildebrand; Martinez,Carlos Alberto; Mestriner,Moacyr Antônio.
An efficient and rapid DNA minipreparation modified method for frozen samples was developed for five tropical tree species: Copaifera langsdorffii, Hymenaea courbaril, Eugenia uniflora, Tabebuia roseo alba and Cariniana estrellensis. This procedure that dispenses the use of liquid nitrogen, phenol and the addition of proteinase K, is an adaptation of the CTAB-based DNA extraction method. The modifications included the use of PVP to eliminate the polyphenols, only one chloroform-isoamyl alcohol step and the addition of RNase immediately after extraction with chloroform. The yields of the DNA samples ranged from 25.7 to 42.1 µg from 100 mg leaf tissue. The DNA samples extracted by this method were successfully used for PCR (SSR and RAPD) analyses in these...

China prioritized a New Socialist Countryside reform policy in 2005 to address the growing disparities in incomes and living standards between rural and urban populations. These policies are evaluated to provide a base line index of reform concerning farmer, agricultural, and rural economic development. Aggregate index scores are computed to rank provincial progress. Rankings indicate the progression of rural economic reform is moderate, at best, and mostly isolated to well-developed eastern provinces. Reform growth is also uneven across similarly, rural provinces indicating a need for continued attention in these poorer areas. More importantly, as reform efforts continue, the empirical framework established can be used to track relative performance over...

An Empirical Evaluation of Poverty Mapping Methodology: Explicitly Spatial versus Implicitly Spatial Approach
Provedor de dados: 31
Autores: Olivia,   Susan; Gibson,   John; Smith,   Aaron D.; Rozelle,   Scott; Deng,   Xiangzheng.
Poverty maps provide information on the spatial distribution of welfare and can predict poverty levels for small geographic units like counties and townships. Typically regression methods are used to estimate coefficients from the detailed information in household surveys, which are then applied to the more extensive coverage of a census. One problem with standard regression techniques is that they do not take into account the ‗spatial dependencies‘ that often exist in the data. Ignoring spatial autocorrelation in the regression providing the coefficient estimates could lead to misleading predictions of poverty, and estimates of standard errors. Household survey data usually lack exact measures of location so it is not possible to fully account for this...

Aedes aegypti is a very efficient disseminator of human pathogens. This condition is the result of evolutionary adaptations to frequent haematophagy, as well as to the colonization of countless types of habitats associated with environmental and cultural factors that favor the proliferation of this mosquito in urban ecosystems. Studies using sensitive methods of monitoring demonstrate that the methods of surveillance used in the Brazilian program do not show the high degrees of the infestation of cities by this vector. To increase the capacity of the health sector, new tools are needed to the practice of surveillance, which incorporate aspects of the vector, place and human population. We describe here the SMCP-Aedes - Monitoring System and Population...

An evaluation of fibrous structure and physical characteristics of Cutia nut (Couepia edulis Prance) shell
Provedor de dados: 36
Autores: Assis,Odílio Benedito Garrido; Pessoa,José Dalton Cruz.
The Cutia-nut (Couepia edulis Prance), a species originally from the Amazon region, has a kernel with reasonable nutritional value and a hard and thick woody shell that constitute most of the fruit. After the kernel removal, the shells are regarded as waste. The possibility of using such shells, as raw material for burning or charcoal production, as well as milled residue for structural reinforcement materials is quite feasible, considering environmental and economical aspects. There is, however, a complete lack of characterization of the Cutia-nut shell and other similar species which can aggregate desirable qualities for application as engineering material. In this study some analyses are presented aiming at providing information for potential uses of...

Autores: TOGNELLI,MARCELO F; ROIG-JUÑENT,SERGIO A; MARVALDI,ADRIANA E; FLORES,GUSTAVO E; LOBO,JORGE M.
Various studies have shown that model performance may vary depending on the species being modelled, the study área, or the number of sampled localities, and suggest that it is necessary to assess which model is better for a particular situation. Thus, in this study we evalúate the performance of different techniques for modelling the distribution of Patagonian insects. We applied eight of the most widely used modelling methods (artificial neural networks, BIOCLIM, classification and regression trees, DOMAIN, generalized additive models, GARP, generalized linear models, and Maxent) to the distribution of ten Patagonian insect species. We compared model performance with five accuracy measures. To overeóme the problem of not having reliable absence data with...

An Evaluation of the Economic Impacts of Oklahoma Farmers Markets
Provedor de dados: 31
Autores: Henneberry,   Shida Rastegari; Whitacre,   Brian E.; Agustini,   Haerani N.
The contribution of farmers markets to the U.S. economy has become more significant due to the increased demand for fresh, locally produced products. However, compared to other marketing outlets, the economic contribution of farmers markets often goes unrecognized. This study focuses on farmers markets in Oklahoma and uses the IMPLAN model to estimate the impacts of farmers markets to Oklahoma’s economy. The results from this study show that farmers market activities are a vital part of Oklahoma’s economy, generating total direct sales of $3.3 million, with a total economic impact of almost $6 million.

Autores: Kandpal,   Eeshani.
The Indian Integrated Child Development Services (ICDS) aims to improve the physical and psychological well-being of children younger than five. However, previous evaluations find that ICDS fails to significantly impact child stunting and that program placement is faulty. My results contradict the lack of a significant treatment effect, but are consistent with problematic program placement. Previous analyses of ICDS used probit to study placement, but the distribution of state-wise ICDS coverage is negatively skewed violating the normality assumption of probit. To address this, I use beta regression to study placement and compare results with probit analysis. In addition, using Propensity Score Matching (PSM) I find evidence of a significant, positive...

An evolutionary approach to Function
Provedor de dados: 17
Autores: Phillip Lord.
The distinction between function and role is a vexed and difficult one. While the distinction appears to be useful, in practice it is hard to apply; this can be even worse when applying this distinction to biology. In this paper, I take an evolutionary approach, considering a series of examples, to develop and generate definitions for these concepts. I test them in practice against work performed on the Ontology for Biomedical Investigations (OBI). Finally, I give an axiomatisation and discuss methods for applying these definitions in practice.

An Evolutionary Edge of Knowing Less (or: On the "Curse" of Global Information)
Provedor de dados: 31
Autores: Stark,   Oded; Behrens,   Doris A.
Consider a population of farmers who live around a lake. Each farmer engages in trade with his two adjacent neighbors. The trade is governed by a prisoner’s dilemma “rule of engagement.” A farmer’s payoff is the sum of the payoffs from the two prisoner’s dilemma games played with his two neighbors. When a farmer dies, his son takes over. The son decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous members of the group comprising his own father and a set of his father’s neighbors. The size of this set, which can vary, is termed the “span of information.” It is shown that a larger span of information can be detrimental to the stable coexistence of cooperation and defection, and that in...

Recent literature, largely from the U.S. Department of Agriculture, Economic Research Service, indicates that substantial changes have occurred in the produce industry in recent years. With the rise of retail mass merchandisers and increased concentration in the retail food industry, the procurement power of these large firms reportedly has also increased. With direct buying and contracting, market intermediaries such as brokers and wholesalers allegedly are being bypassed. As a result, these market intermediaries ostensibly are also consolidating becoming fewer and larger with increased emphasis on servicing the food service industry. However, the findings of this study indicate that there is no convincing evidence that the market structure of the U.S....

The term traceability refers to recording of flow of products along the food chain from production to consumption with inclusion of all intermediate applications involved in processing/packaging stages. The aim for establishing traceability in the food chain is to provide the timely identification and recall of batches of product from the market when a risk threatens the health of consumers. Since compound feed products are basic inputs in livestock and poultry production, ICT-based feed traceability systems can be considered as a initial step in food traceability management. These systems are simply information recording systems that are designed to trace and track the flow and characteristics of animal feed along the feed supply chain. This paper...

An illusion induced by an illusion -perceptual filling-in of coloured negative afterimages
Provedor de dados: 17
Autores: Adam Geremek; Kai Hamburger; Lothar Spillmann.
Visual filling-in relates to a perceptual phenomenon in which a stimulus pattern apparently undergoes dynamic changes assuming an attribute such as colour, texture, or brightness from the surround. This perceptual completion effect has up to now been shown only for real images. Here, we present filling-in in negative afterimages, a phenomenon not yet reported. Using coloured disk-ring patterns for stimuli, we demonstrate that afterimage filling-in arises independently, and is not simply a replica of filling-in observed in real images. Such filling-in does not occur when the afterimage is elicited dichoptically, suggesting its emergence within the monocular visual pathway. In this way, our findings indicate that filling-in under certain conditions may...

Provedor de dados: 82
Autores: Noll,Fernando B; Gomes,Bruno.
In this work, an alternative method for the capture of neotropical social wasps is described, which may supplement or replace the procedures commonly used in wasp surveys. The method was tested in a seasonal semideciduous forest in the northwest of São Paulo State, collecting a larger number of species and a greater abundance of social wasps and of other Hymenoptera than other methods also used in the same area, namely Malaise traps, bottle traps and meat baits. The proposed method was adapted from Wille (1962) who used an attractive solution based on water and honey for bee attraction. In here, the attractive solution was based on water, salt and crystal sugar, and was effective in attracting bees and solitary wasps, but mainly social wasps, which is the...

An improved method for characterization of the mutation associated to porcine stress syndrome by PCR amplification followed by restriction analysis
Provedor de dados: 65
Autores: Luerce,Tessália Diniz; Galli,Vanessa; Cerqueira,Gustavo Maia; Simionatto,Simone; Dellagostin,Odir Antônio.
A mutation in the gene coding for the ryanodine receptor 1 (RYR1), also known as halothane (hal) gene or swine stress gene, is associated to the porcine stress syndrome (PSS). Detection of the mutation is normally accomplished by PCR amplification of an 81bp fragment of the hal gene, followed by digestion with the HhaI restriction endonuclease. Wild-type allele (N) is cut in two fragments, whereas the mutant allele (n) is not digested by the restriction enzyme. Electrophoresis of the digested DNA on agarose gel and ethidium bromide staining allows the reading of the result. The correct interpretation is difficult due to the small size of the DNA fragments. In this study we designed a new set of primers for amplification of a 144bp fragment that facilitates...

An improvement of calcium determination technique in the shell of molluscs
Provedor de dados: 52
Autores: Soído,Cristiane; Vasconcellos,Maurício Carvalho; Diniz,Antônia Gonçalves; Pinheiro,Jairo.
The complexometric method is usually applied to quantitative calcium determination in different materials; however the application of this method to calcium determination in molluscs shells infers significant interferences to the results. The snail Bradybaena similaris, a terrestrial gastropod, was used as experimental model to the improvement of this method.

An Integrated Assessment of Climate Change, Air Pollution, and Energy Security Policy
Provedor de dados: 31
Autores: Bollen,   Johannes; Hers,   Sebastiaan; van der Zwaan,   Bob.
This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE with expressions that quantify damages incurred to regional economies as a result of air pollution and lack of energy security. One of the main findings of our cost-benefit analysis is that energy security policy alone does not decrease the use of oil: global oil consumption is only delayed by several decades and oil reserves are still practically depleted before the end of the 21st century. If, on the other hand, energy security policy is integrated with optimal...

This study introduces a prototype model for evaluating policies to abate agricultural nutrients in the Baltic Sea from a Finnish national point of view. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient loads from land and other sources, benefits from nutrient abatement (in the form of recreation and other ecosystem services) and the costs of agricultural abatement activities. The aim of this study is to present the overall structure of the model and to demonstrate its potential using preliminary parameters.

An integrative approach to species delimitation in Benthomangelia (Mollusca: Conoidea)
Provedor de dados: 5
Autores: Puillandre, Nicolas; Baylac, Michel; Boisselier, Marie-catherine; Cruaud, Corinne; Samadi, Sarah.
DNA sequences are currently used to propose primary hypotheses of species delimitation, especially when morphological variability is difficult to assess. In an integrative taxonomy framework, these hypotheses are then compared with other characters, such as morphology or geography, to produce robust species delimitations. For this purpose, the cytochrome oxidase subunit I (COI) gene has been sequenced for almost 50 specimens of the genus Benthomangelia, a deep-sea marine gastropod genus, collected in the South-West Pacific. Five genetic groups, displaying low and high genetic distances respectively within and between groups, were defined. COI hypotheses were compared with both the results obtained with the independent nuclear 28S gene and with an elliptic...

An introduction to the flora of the Milne Bay Archipelago
Provedor de dados: 16
Autores: Johns, R.; Gideon, O.; Simaga, J.; Kuria, T.; Bagoera, G.
The term Milne Bay Archipelago is used to include Goodenough, Fergusson and Normanby Islands – collectively the d’Entrecasteau Islands, the islands of the Louisiade Archipelago, Missima, Rossel and Sudest Islands and the two northern islands, the Trobriands and Woodlark. All are very complex with many small islands, often unnamed. Due to their geographic isolation the islands have many endemic species. So far 139 have been described. Of particular interest is the genus Rosselia, collected only twice from Rossel Island. This monotypic genus was placed, with many questions, in the Burseraceae and its current position is uncertain. Another neoendemic genus in Milne Bay is Lamiodendendron. It is a coastal tree scattered on several islands and also coastally on...

The present study provides an empirical investigation of the supply chain of fisheries products in Greece, through the implementation of the Structure – Conduct and Performance (SCP) methodological approach. The determinants of market performance have been analyzed considering the causal relationship of industry structure and firm conduct, and consecutively the causal relationship of firm conduct and market performance. Primary data were collected from Greek fisheries products stakeholders through personal interviews. The findings reveal that firm conduct is affected by industry structure and sequentially both have a bearing upon market performance. As concerns the impact of firm conduct on market performance, quality assurance has the most significant...

An offside position in football cannot be detected in zero milliseconds
Provedor de dados: 17
Autores: Francisco Belda Maruenda.
Errors when judging an offside position in football are very frequent. In the last years, several scientific papers have tried to explain the causes for human errors. When a referee or an assistant referee misjudges an offside position, it is thought to be caused by a human error. A human error means to carry out incorrectly an action we are physiologically qualified for. The hypothesis to be studied in this paper is if when judging an offside position it is possible to attribute errors to humans or to the fact that human physiology and the technical media are not capable of detecting an offside position. The offside rule has to be applied in real time, in zero milliseconds, in the precise moment when the ball is being passed, never 1 millisecond or even 1...

Autores: Thomas W&amp;#xe4;chter; Ursula G. Sauer; Andreas Doms; Barbara Grune; Michael R. Alvers; Horst Spielmann; Michael Schroeder.
EU Directive 86/609/EEC for the protection of laboratory animals obliges scientists to consider whether a planned animal experiment can be replaced, reduced or refined (3Rs principle). To meet this regulatory obligation, scientists must consult the relevant scientific literature prior to any experimental study using laboratory animals. More than 50 million potentially 3Rs relevant documents are spread over the World Wide Web, biomedical literature and patent databases. In April 2008, the beta version of Go3R (&amp;#x22;www.Go3R.org&amp;#x22;:http://www.Go3R.org), the first knowledge-based semantic search engine for alternative methods to animal experiments, was released.

An Ontology-Based Framework for Clinical Research Databases
Provedor de dados: 17
Autores: Richard H. Scheuermann; Megan Kong; Carl Dahlke; David Karp.
The Ontology-Based eXtensible data model (OBX) was developed to serve as a framework for the development of a clinical research database in the Immunology Database and Analysis Portal (ImmPort) system.  OBX was designed around the logical structure provided by the Basic Formal Ontology (BFO) and the Ontology for Biomedical Investigations (OBI).  By using the logical structure provided by these two well-formulated ontologies, we have found that a relatively simple, extensible data model could be developed to represent the relatively complex domain of clinical research.  In addition, the common framework provided by the BFO should make it straightforward to utilize OBX database data dictionaries based on reference and application ontologies from the OBO...

Autores: VEYSSET, P.; GLOUTON, J.; BEBIN, D.; BECHEREL, F.
in the Massif Central. An organic suckler cattle farm network was set up in order to establish technical and economic references. In 2004, 22 farms were monitored (13 of which had been monitored since 2001). All of these farms are located in economically-depressed areas. One hundred percent of the fodder area is under grassland. Annual crops (cereals and a cereal/pulse mix) take up 13% of the farm area and are used as livestock feed. The stocking rate (1 Livestock Unit/ha of fodder area) is 20% lower on organic farms than on conventional farms. Organic farms use 33% less concentrates per LU, and the meat production/LU is 16% lower than for conventional farms. The poorly structured organic beef market forces organic farmers to sell most of their animals...

An outbreak of winter dysentery caused by bovine coronavirus in a high-production dairy cattle herd from a tropical country
Provedor de dados: 52
Autores: Takiuchi,Elisabete; Barry,Aline Fernandes; Alfieri,Alice Fernandes; Filippsen,Patrícia; Alfieri,Amauri Alcindo.
Bovine coronavirus (BCoV) is a known cause of winter dysentery (WD) in adult cattle. The morbidity of the disease is high, that results in a significant decrease in milk production and consequently, economic losses. In the present study, we report on a classical outbreak of WD that affected a high-production Holstein dairy herd raised in a tropical country. The lactating batch included 154 cows, and 138 (90%) presented diarrhea in a short (nine days) period of time. Three (2%) cows died. The other batches of animals did not become ill. The evolution of the disease in the herd, including the clinical signs and epidemiological features, strongly suggested a WD case. Semi-nested PCR and RFLP confirmed that BCoV was the cause of the infection. Samples tested...

Mammals are among the most charismatic and well-studied organisms, and Brazil harbors the largest mammal diversity of the world. The Brazilian Society of Mammalogy was established in 1985, and since 2001 it organizes the Brazilian Congress of Mammalogy. We used the proceedings of all three editions of this congress together with papers indexed in Web of Science and Scielo to evaluate trends in Brazilian mammalogy. All contributions were categorized according to mammalian order, biome, topic of research and state of authors' affiliation. Our results show that mammalian orders with higher species richness receive more attention, but the ranking is different between abstracts and papers. Higher species richness did not translate into more attention for more...

The 2008 farm bill involved 16 months of debate. The end product is similar to the 2002 farm bill in the crops arena, continuing counter-cyclical payments, direct payments, and marketing assistance loans. In addition, however, the 2008 bill adds a new, optional counter-cyclical revenue program (Average Crop Revenue Election, or ACRE), authorizes a new permanent disaster program, and contains various other changes. The new ACRE program provides an entirely new set of dimensions for producers to consider in deciding whether to opt into the program, including the multi-year trade-off between the loss of potential “traditional” payments and the revenue protection provided by ACRE, as well as the producer’s own expectations about yield and price trends and...

An overview on molecular markers for detection of ochratoxigenic fungi in coffee neans
Provedor de dados: 52
Autores: Fungaro,Maria Helena Pelegrinelli; Sartori,Daniele.
Ochratoxin A (OTA) is one of the most abundant food-contaminating mycotoxins. Its occurrence in several agricultural commodities has been considered a worldwide problem. This toxin is mainly produced by Aspergillus species. OTA has nephrotoxic, immunosuppressive, and carcinogenic effects and consequently the contamination with this toxin represents a high risk for human and animal health. In the last 5 years, several investigators have applied molecular methods in order to develop PCR assays for identifying and quantifying OTA-producing fungi in coffee beans samples. The main objective is to allow the detection of microorganisms capable of producing OTA, preferentially prior to ochratoxin production and accumulation. In this contribution several of these...

Lipids can be systematically classified according to functional properties, structural features, biochemical origin or biological system. However Lipid nomenclature has yet to become a robust research tool since no rigorous definitions exist for membership of specific lipid classes. Lipids need to be defined in a manner that is systematic yet at the same time semantically explicit. We report on the reuse of existing lipid nomenclature, ontology describing chemical structure and the extension of the OWL-DL Lipid Ontology to support the classification of lipid molecules. We applied definitions, DL-axioms, to describe lipids classes and illustrate suitability of the ontology for the classification of Fatty Acyl lipids and Mycolic acids.

Following the notification of nine hepatitis A cases clustered in the Cotes d'Armor district in northwestern France, epidemiological, environmental and microbiological investigations were set up in order to identify the source and vehicle of contamination and implement control measures. In total, 111 cases were identified in the outbreak, all of whom lived or had stayed as tourists in the Cotes d'Armor district. Of the cases, 87% had eaten raw shellfish, and 81% specifically oysters. Traceback investigations carried out on raw shellfish consumed by the cases showed that the raw shellfish originated from a single shellfish farm. The shellfish were probably contaminated either in the submersible tanks or in a depuration land-based tank where they were...

In addition to its characteristics as a DNA binding transcription factor, HMGA1a is known to bind RNA, sequence specifically and regulate aberrant splicing of the _Presenilin-2_ gene in sporadic Alzheimer&amp;#x2019;s disease^1,2^. We show here that an RNA _cis_-element, immediately upstream the HMGA1a binding site, induces exon inclusion upon mutating a GU sequence to CA. Psoralen mediated UV crosslinking showed U1 snRNP did not bind this sequence but oligonucleotide-mediated RNase H digestion showed it important for U1 snRNP to recognize the authentic 5&amp;#x2019; splice site.

An Unusual Termination of Seven Veins in the Jugulo-Subclavian Junction
Provedor de dados: 77
Autores: Panagouli,Eleni; Tsaraklis,Athanasios; Gazouli,Ioanna; Venieratos,Dionyssios.
During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

An Updated Look at the Recovery of Agricultural Productivity in Sub-Saharan Africa
Provedor de dados: 31
Autores: Nin Pratt,   Alejandro; Yu,   Bingxin.
We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 40 years, looking for evidence of recent changes in growth patterns using a nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture during between 1984 and 2003 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs, including an overall net reduction in fertilizer use but increased fertilizer use in most of the best-performing countries. Policy changes implemented by African countries between the mid-1980s and the second...

Provedor de dados: 52
Autores: Del-Vechio-Vieira,Glauciemar; Sousa,Orlando Vieira de; Miranda,Mariza Abreu; Senna-Valle,Luci; Kaplan,Maria Auxiliadora Coelho.
The chemical composition, analgesic and anti-inflammatory properties of essential oil from Ageratum fastigiatum were investigated. The main compounds found in the essential oil were germacrene D, α-humulene and β-cedrene. The oil, with LD50 of 2.50 g/kg, inhibited the acetic acid-induced writhing at the dose of 200 mg/kg. In the formalin test, the oil inhibited the first phase (200 mg/kg) and the second phase (100 mg/kg and 200 mg/kg). In the hot plate test, after 30 and 60 min of treatment the doses of 100 and 200 mg/kg increased the reaction time. The antiedematogenic effect, reduction on the exudate volume and leukocyte mobilization were observed at the doses of 100 and 200 mg/kg. The results indicated that A. fastigiatum possessed the analgesic and...

Análise agroecológica de dois paradigmas modernos.
Provedor de dados: 21
Autores: Goulart, Fernando; Vandermeer, John; Perfecto, Ivette; Matta-Machado, Rodrigo P.
O presente estudo é uma revisão sobre a contribuição da agroecologia para o debate conservacionista e desenvolvimentista. O discurso tradicional da biologia da conservação traz um enfoque exclusivo nas unidades de conservação (UCs), prejudicando os esforços de preservação da matriz paisagística como todo. Por outro lado, o discurso pautado por alguns desenvolvimentistas é levado por uma diferente, mas não menos equivocada, corrente de pensamento que acredita na superioridade da produção agrícola intensiva frente à agricultura familiar. No Brasil, essa modernização precoce da agricultura teve consequências catastróficas para o pequeno produtor bem como levou o aumento da pobreza no campo e nas cidades. Através da crítica agroecológica, ambas as correntes, a...

Análise bayesiana do modelo de herança monogênica no melhoramento vegetal: um exemplo com abobrinha
Provedor de dados: 64
Autores: Silva,Maria Imaculada de Sousa; Bearzoti,Eduardo; Bueno Filho,Júlio Sílvio de Sousa.
Uma estratégia comum em programas de melhoramento é conduzir estudos básicos de herança para investigar a hipótese de controle do caráter por um ou poucos genes de efeito principal, associados ou não a genes modificadores de pequeno efeito. Neste trabalho, foi utilizada a inferência bayesiana para ajustar modelos de herança genética aditiva-dominante a experimentos de genética vegetal com várias gerações. Densidades normais com médias associadas aos efeitos genéticos das gerações foram consideradas em um modelo linear em que a matriz de delineamento dos efeitos genéticos tinha coeficientes indeterminados (precisando ser estimada para cada indivíduo). A metodologia foi ilustrada com um conjunto de dados de um estudo de herança da partenocarpia em abobrinha...

Provedor de dados: 45
Autores: Faria,C.U.; Magnabosco,C.U.; Albuquerque,L.G.; de los Reyes,A.; Bezerra,L.A.F.; Lôbo,R.B.
Estimaram-se as correlações genéticas entre os escores visuais e as características reprodutivas, utilizando a estatística bayesiana sob modelo animal linear-limiar, em bovinos da raça Nelore. Foram estudadas características categóricas morfológicas, avaliadas visualmente aos oito, 15 e 22 meses de idade; e características contínuas de perímetro escrotal padronizado aos 365 e 450 dias de idade, além da idade ao primeiro parto. As estimativas de correlações genéticas foram de sentido favorável à seleção, apresentando magnitudes moderadas, sugerindo que a seleção de animais para um biótipo desejável pode levar a animais com maior fertilidade e precocidade sexual. As estimativas de correlação genética para o perímetro escrotal padronizado aos 450 dias e a...

Análise Bayesiana no estudo do tempo de retorno das precipitações pluviais máximas em Jaboticabal (SP)
Provedor de dados: 64
Autores: Beijo,Luiz Alberto; Vivanco,Mário Javier Ferrua; Muniz,Joel Augusto.
Dados históricos de precipitação máxima são utilizados para realizar previsões de chuvas extremas, cujo conhecimento é de grande importância na elaboração de projetos agrícolas e de engenharia hidráulica. A distribuição generalizada de valores extremos (GEV) tem sido aplicada com freqüência nesses tipos de estudos, porém, algumas dificuldades na obtenção de estimativas confiáveis sobre alguma medida dos dados têm ocorrido devido ao fato de que, na maioria das situações, tem-se uma quantidade escassa de dados. Uma alternativa para obter melhorias na qualidade das estimativas seria utilizar informações dos especialistas de determinada área em estudo. Sendo assim, objetiva-se neste trabalho analisar a aplicação da Inferência Bayesiana com uma distribuição a...

Análise comparativa do ambiente de aviários de postura com diferentes sistemas de acondicionamento
Provedor de dados: 91
Autores: Vitorasso,Guilherme; Pereira,Danilo F.
As tipologias dos galpões de galinhas poedeiras e os materiais utilizados principalmente na cobertura são determinantes para uma condição térmica apropriada com vistas à produção. Neste contexto, o objetivo deste trabalho foi identificar diferenças no ambiente interno de dois galpões de poedeiras, utilizando monitoramento e posterior comparação estatística das variáveis do ambiente. A análise dos dados não evidenciou maior conforto térmico no galpão recoberto com telhas de barro, em razão da ausência de lanternim que dificultou a renovação do ar por "efeito chaminé". A concentração de amônia medida no interior de ambas as instalações ficou dentro do limite de conforto. O índice de temperatura e umidade do galpão recoberto com telhas de cerâmica apresentou...

Provedor de dados: 87
Autores: Souza Filho,A.P.S.; Guilhon,G.M.S.P.; Zoghbi,M.G.B.; Cunha,R.L.
A alelopatia é um importante mecanismo que influencia a estabilidade de agroecossistemas. A identificação desse caráter, em muitos casos, realiza-se via análise dos efeitos de extratos brutos polares. No presente trabalho, caracterizou-se a atividade alelopática do cipó-d'alho (Mansoa standleyi - Bignoniaceae), analisando-se, comparativamente, o extrato hidroalcoólico e o óleo essencial das folhas da planta, procurando-se estabelecer a necessidade de se considerar, em estudos dessa natureza, a abordagem envolvendo extratos apolares. Realizaram-se bioensaios de germinação e desenvolvimento da radícula e do hipocótilo de malícia (Mimosa pudica), em períodos de dez dias, empregando-se concentrações de 0,5%, 1,0% e 2,0%.

Análise comparativa dos custos de produção de duas propriedades leiteiras, no município de Unaí-MG, no período de 2003 e 2004
Provedor de dados: 64
Autores: Carvalho,Francisval de Melo; Ramos,Érika Oliveira; Lopes,Marcos Aurélio.
Objetivou-se, neste estudo comparar os custos de produção do leite de duas propriedades localizadas no município de Unaí - Minas Gerais, e a influência deles na lucratividade. Trata-se de um estudo de dois casos, cujos dados foram extraídos de planilhas de análise técnico-gerencial das propriedades, nos anos de 2003 e 2004. Observou-se uma diferença entre os custos apurados, principalmente em função do nível tecnológico adotado. Pôde-se concluir que o aumento de escala de produção diluiu os custos fixos da atividade, diminuindo o custo total e aumentando as margens; que o uso de tecnologias viáveis possibilita uma melhor resposta do sistema a diversos fatores de produção, permitindo uma adaptação mais rápida, o que influenciará no retorno financeiro....

Autores: Grunow,   Aloisio; Gallon,   Alessandra Vasconcelos; Beuren,   Ilse Maria.
In a competitive environment, it is not enough to simply coordinate and promote the efficiency of a company’s internal activities. It is also necessary to ensure that the activities which form part of the company’s “value chain” are organized in a competitive way. From this perspective, the objective of this article is to analyze the “value chain” of poultry production and the cost of animal feed in every phase of the Seara Alimentos S.A chain. The methodology consisted of exploratory research in a case study using a predominantly qualitative approach. The results of the study are the stages of the productive cycle and the costs of the animal feed throughout the “value chain” in a poultry agribusiness. It was concluded that estimating the production’s...

Autores: Costa,Thomaz C. e C. da; Oliveira,Maria A. J. de; Accioly,Luciano J. de O.; Silva,Flávio H. B. B. da.
A condição de aridez associada à pressão antrópica resulta em áreas de degradação extrema, conhecidas como núcleos de desertificação. No núcleo do Seridó a antropização é caracterizada por queimadas, cultivo do algodão no passado, pastoreio e exploração de lenha, que alteraram a composição florística e a estrutura da vegetação potencial. Com este estudo se objetivou identificar níveis de degradação na caatinga arbóreo-arbustiva do Seridó, por meio de técnicas multivariadas que envolveram variáveis do ambiente físico, da florística, fitofisionomia e diversidade da vegetação. O inventário florístico e fitossociológico foi realizado em 16 fragmentos, pelo método Ponto-Quadrante, com a inclusão de plantas com diâmetros no nível do solo 1 cm e altura ≥ 1 m,...

Análise da eficiência do mercado futuro brasileiro de boi gordo usando co-integração
Provedor de dados: 123
Autores: Moraes,André Steffens; Lima,Ricardo Chaves; Melo,André de Souza.
A hipótese de que os preços futuros são preditores não viesados dos preços à vista é uma hipótese conjunta de que os mercados são eficientes e que não existe prêmio ao risco. Entretanto, na presença de prêmio ao risco, a hipótese de não viés pode ser rejeitada mesmo quando o mercado é eficiente. Este artigo testa a eficiência do mercado futuro brasileiro do boi gordo na presença de prêmio ao risco, usando técnicas de co-integração. Os resultados mostram que o mercado futuro do boi gordo é eficiente e não viesado no longo prazo, independente da presença de prêmio ao risco.

Autores: CARDOSO, E. L.; FERNANDES, A. H. B. M.; FERNANDES, F. A.
A análise de solos é o único método que permite, antes do plantio, conhecer a capacidade de um determinado solo suprir nutrientes para as plantas. É a forma mais simples, econômica e eficiente de diagnose da fertilidade das terras e constitui base imprescindível para a recomendação de quantidades adequadas de corretivos e fertilizantes para aumentar a produtividade das culturas e, como consequência a produção e a lucratividade das lavouras.

Análise de trilha dos componentes do rendimento de sementes de trevo-branco
Provedor de dados: 96
Autores: Lopes,Rodrigo Ramos; Franke,Lúcia Brandão.
Objetivou-se, por meio de uma análise de trilha para rendimento de sementes em trevo-branco, obter informações básicas para utilização em estratégias de manejo para maior produção de sementes e maior ressemeadura natural, proporcionando assim condições para maior persistência da espécie na pastagem. Foram analisadas as seguintes variáveis: botões florais, número de inflorescências, número de inflorescências maduras, número de legumes/inflorescência, peso de 100 sementes e rendimento de sementes. A variável que mais se correlacionou com o rendimento de sementes foi o número de inflorescências maduras (r = 0,91) e essa correlação ocorreu praticamente apenas pelo seu efeito direto. Nas demais variáveis, destacou-se o número de botões florais, com coeficiente...

Análise do segmento de vinhos finos em função do surgimento de novos empreendimentos vitivinícolas.
Provedor de dados: 14
Autores: GUERRA, C. C.
Pela evolução apresentada nos últimos anos, o segmento dos vinhos finos da vitivinicultura brasileira constitui-se em um caso particular e interessante. De fato, no final da última década do século passado, o cenário vitivinícola internacional era de expansão e otimismo. Nesse contexto, vários empresários brasileiros iniciaram empreendimentos, a maioria localizada fora das tradicionais regiões produtoras. Como resultado dos investimentos efetuados, novos pólos de produção surgiram e se consolidaram; o número de estabelecimentos vinificadores aumentou, assim como o número de marcas comerciais. Também a tecnologia empregada na produção vitivinícola melhorou, especialmente a enológica.

Análise e quantificação do risco para a gestão eficiente do portfólio agrícola das seguradoras
Provedor de dados: 123
Autores: Ozaki,Vitor Augusto; Dias,Carlos Tadeu dos Santos.
A presença de eventos considerados catastróficos pode comprometer o balanço financeiro da carteira agrícola das seguradoras. Por exemplo, a estiagem pode afetar não somente um produtor, mas milhares de produtores em uma vasta extensão territorial. Para contornar esse problema, as seguradoras podem diversificar geograficamente suas operações. Nesse sentido este estudo aplica a análise de agrupamentos em um conjunto de dados de produtividade municipal de milho, no período de 1990 a 2005, para o estado do Paraná. Ao todo, 39 grupos foram formados conforme características similares de produtividade esperada e risco relativo. Para que as perdas sejam minimizadas, o estudo exclui alguns municípios de alto risco e sugere a classificação dos grupos, de acordo com...

Provedor de dados: 65
Autores: Braga,Celso de Oliveira; Abrahão,Roberto Funnes; Tereso,Mauro José Andrade.
O beneficiamento pós-colheita é uma atividade em grande expansão no Brasil. Neste estudo adotou-se a abordagem ergonômica para analisar as exigências laborais em unidades de beneficiamento de tomate de mesa (UB). Aplicou-se o método da Análise Ergonômica do Trabalho para identificar os postos de trabalho de maiores exigências laborais. Na pesquisa de campo envolvendo 61 operadores, foram utilizados o Método NASA TLX e o Questionário de Avaliação Visual. A exigência mental foi elevada nos postos de trabalho de bicas e seleção. A exigência visual foi elevada nas UB de baixos níveis de iluminância, e a exigência física foi alta nos postos de alimentação de todas UB e nas bicas das UB que não contavam com auxílio mecânico para movimentação de caixas.

Objetivos e pressões econômicas, políticas e ambientais serão, de modo crescente, importantes drivers para a adoção de tecnologia. Os sistemas de integração lavoura-pecuária têm sido propostos como solução tecnolíogica para atender critérios de sustentabilidade, mas tal assertiva tem se baseado fortemente em indicadores agronômicos e ambientais. Nesta publicação, explorou-se o desempenho econômico e do investimento nesses sistemas mistos. O risco foi preliminarmente acessado por meio de variações no rendimento da lavoura e nas taxas de lotação. Considerando coeficientes técnicos gerados pela pesquisa e observações de campo, a preços de mercado do último trimestre de 2008, os sistemas de integração lavoura-pecuária com elevado uso de insumos apresentaram...

Análise morfométrica em Thoracocharax stellatus (Kner, 1858) (Characiformes, Gasteropelecidae) proveniente de diferentes bacias hidrográficas Sul-americanas
Provedor de dados: 49
Autores: Silva,Edson Lourenço da; Centofante,Liano; Miyazawa,Carlos Suetoshi.
Foram utilizadas análises de variáveis canônicas livres de tamanho com o objetivo de investigar os padrões de variação morfológica entre populações de Thoracocharax stellatus em bacias hidrográficas Sul-Americanas: rios das bacias Araguaia-Tocantins e Paraguai do Brasil e Orinoco na Venezuela. Distinções entre as amostras do Araguaia-Tocantins e Orinoco foram observadas, com leve sobreposição dessas populações com as amostras da bacia do Paraguai. Os caracteres morfométricos que são os principais responsáveis por esta diversificação são comprimento da cabeça e comprimento da nadadeira dorsal. Os mecanismos que podem estar atuando nesta variação geográfica entre populações de T. stellatus são discutidos.

Análises estatísticas das tendências de elevação nas séries anuais de temperatura mínima do ar no Estado de São Paulo
Provedor de dados: 53
Autores: Blain,Gabriel Constantino; Picoli,Michelle Cristina Araujo; Lulu,Jorge.
Considerando que algumas investigações sobre o tema aquecimento global utilizam longas séries temporais de temperatura uma questão que deve ser levantada é relativa a influência de possíveis concentrações de fontes de calor urbano a que os postos meteorológicos possam estar submetidos. O primeiro passo para responder a essa questão é verificar se, em uma mesma região, ocorrem tendências concomitantes de elevação nos dados de temperatura em diversas localidades, possivelmente ligadas a fenômenos de escala global. Entretanto, se essa elevação tiver seu início em períodos bastante distintos entre as diversas localidades, o descarte de forçantes radioativas locais como principais responsáveis por esse aumento, dificilmente poderá ser realizado.

Autores: Dominguez,   Juan M.; Espinel,   Ramon L.
Increases in petroleum prices have affected the prices of its derived products. In addition, the interest in issues related to the environment and energy security at world-wide level has been increased. All of these factors have contributed to the development of alternative fuel such as the ethanol, biodiesel and natural gas. This study analyzes the main agricultural products used to produce biodiesel, their production costs and the utilization of those inputs in other industries. This study will also include a brief summary of different legislations in those countries under analysis. On the other hand, we will find break-even points and apply a sensibility analysis associated with distinct scenarios in terms of input-output prices.

Análisis de la Expresión de Receptores de Estrógenos y Progesterona en el Endometrio de Ovejas de las Razas Romney Marsh y Araucana
Provedor de dados: 77
Autores: Vasconcellos C,Adriana; Paredes H,Marco; Carrasco R,Johanna; Núñez R,Daniela.
El estado morfo funcional del tracto genital de las ovejas hembra es determinado por las hormonas sexuales, las que actúan a través de receptores específicos. Éstos regulan la expresión de numerosas proteínas comprometidas en el desarrollo del endometrio. Posiblemente, el desempeño reproductivo de diferentes razas de ovejas podría estar determinado por la expresión diferencial de los receptores. El objetivo del presente estudio fue analizar la presencia de receptores de estrógenos (RE) y progesterona (RP) en el endometrio de ovejas prepúberes y en ciclo, de las razas Romney Mash y Araucana. La histología del endometrio se realizó en cortes de 5 um teñidos con hematoxilina y eosina. La presencia de ambos receptores se detectó mediante inmunohistoquímica,...

Los efectos de la nutrición en reproducción ovina han sido estudiados por numerosos autores. Principalmente, el interés se ha centrado en los efectos de la calidad de la dieta ya que en ovinos sometidos a planos nutricionales bajos se ha observado anormalidades del embrión, fase lutea inadecuada, deficiencia en el aporte de progesterona al útero y falla en los mecanismos que comprenden el reconocimiento materno a la preñez. Existen trabajos sobre la relación alimentación-hormonas sin embargo la información existente sobre los receptores de hormonas esteroidales endometriales, indispensables para que ellas actúen, es muy escasa. El objetivo del presente estudio fue analizar comparativamente la expresión del receptor de estrógenos (RE) en el endometrio de...

Análisis de la metodología de los puntos de corte para la identificación de las respuestas “inconsistentes” en los modelos de elección discreta
Provedor de dados: 31
Autores: Colombo,   Sergio; Hanley,   Nick; Bush,   Glenn.
En el método del experimento de elección se supone que el entrevistado es perfectamente racional, está informado y maximiza su utilidad siguiendo una regla de elección perfectamente compensatoria. Sin embargo, es posible que los individuos empleen otras reglas de decisión en sus elecciones para simplificar el esfuerzo cognitivo del ejercicio propuesto. En este trabajo se emplea la metodología de los valores de corte para incorporar en el experimento de elección reglas de decisión no compensatorias, y se amplia esta metodología para identificar respuestas inconsistentes. Los resultados indican que el empleo de los valores de corte mejora la capacidad descriptiva de los modelos de elección, y puede ser muy útil para la identificación de inconsistencias en la...

Autores: Mesa, Pablo Edgardo.
Como resultado de la recesión hacia fines del 2001 vivir de lo que la sociedad descartaba comenzó a constituir para miles de habitantes la única actividad posible. Este grupo de nuevos cartoneros o cirujas, gran parte de desocupados que iba dejando la crisis, ha sido el objeto de estudio. Su abordaje ha estado en la intersección conflictiva entre una antropología social preocupada por describir las prácticas y un análisis politológico capaz de reflexionar sobre las intervenciones estatales hacia este grupo al que se lo ha dividido en dos: recuperadores tendientes a la integración social y recuperadores tendientes a la mera supervivencia. Como objetivos centrales se han analizado las diferentes historias de vida para explicar el qué hacen y comprender el...

Análisis de la utilización de la captura por unidad de esfuerzo de pescadilla de red (Cynoscion guatucupa) como índice de abundancia anual. Período 1992-2004
Provedor de dados: 20
Autores: Perrotta, R.G.; Ruarte, C.O.
The stripped weakfish (Cynoscion guatucupa)  caught in Brazil, Uruguay and Argentina (SW Atlantic) has a wide latitudinal distribution (22° S-43° S). In Argentina there are two main fishing areas, the Argentine-Uruguayan Common Fishing Zone and 'El Rincón', southern zone of the Buenos Aires littoral. The importance of the species makes it necessary to define an annual abundance index that would allow to diagnose the state of the stock. The model adjusted to calculate the index is the General Linear Model. The factors used were Year, Quarter, Length, Stratum (4 categories) and sub-areas (5 categories), all statistically significant. The problem generated by the presence in the model of first order interactions that include the Year factor is discussed. The...

Análisis de la variabilidad craneométrica en Ctenomys talarum (Rodentia, Ctenomyidae)
Provedor de dados: 81
Autores: García Esponda,César M.; Moreira,Germán J.; Justo,Enrique R.; De Santis,Luciano J. M.
Se llevó a cabo un análisis morfométrico craneano en cinco poblaciones de Ctenomys talarum, las cuales representan a las tres subespecies nominales reconocidas para esta especie de tuco-tuco (i.e., C. t. talarum, C. t. recesus y C. t. occidentalis). Se analizaron la variación geográfica craneana y el dimorfismo sexual. Para el estudio de variación geográfica, se llevaron a cabo dos análisis discriminantes, uno a partir de los datos originales y otro a partir de datos a los que se les eliminó previamente el efecto del tamaño, es decir, los cambios en las proporciones del cráneo debidos a la variación en el tamaño de los especímenes. Los resultados obtenidos indicaron que en esta especie existe un dimorfismo sexual significativo, por lo que los análisis de...

Análisis de las políticas agrícolas aplicadas en el Ecuador en los noventas desde la perspectiva de la soberanía alimentaria
Provedor de dados: 122
Autores: Bravo Robles, Ana Lucía.
La soberanía alimentaria desde un enfoque teórico, es un concepto formulado por la Vía Campesina, en 1996,  que  busca situar como actores centrales de la agricultura a las comunidades y pueblos: campesinos, indígenas, pescadores y recolectores; quienes para recuperar el control de la producción de alimentos deben tener el control de los recursos productivos: tierra, agua, semillas. La soberanía alimentaria surge como una respuesta alternativa a las políticas agrícolas de tendencia neoliberal aplicadas en los países del sur.

La recopilación de información histórica, tales como mediciones de corrientes, oleaje y viento no ha sido suficiente para describir la dinámica del seno Reloncaví. Sin embargo, a pesar de la información parcelada, las altas magnitudes de corrientes en las zonas de Chaica, Quillaipe y El Paso Nao nos permiten inducir que las corrientes baroclínicas modulan fuertemente la dinámica de la cuenca. Por otro lado, los vientos mostraron una alta variabilidad estacional y son modulados por la línea de costa, siendo estos en parte responsables de la circulación y el oleaje superficial. Además, la circulación superficial en los primeros 10 m esta fuertemente modulada por el ingreso de aguas dulce del estuario de Reloncaví. Además, la máxima amplitud del nivel del mar...

Autores: Ramirez,   Juan Andres; Rosales Alvarez,   Ramon.
Las altas concentraciones de gases de efecto invernadero, específicamente CO2, han sido señaladas como la principal causa del cambio climático. La adopción de prácticas agrícolas capaces de incrementar el contenido de carbono en el suelo, ha sido propuesta como una estrategia de bajo costo y disponibilidad inmediata para enfrentar este fenómeno. La Bio-carbonización es una de estas prácticas agrícolas, la cual implica la aplicación de carbón vegetal al suelo, de modo que el carbono queda capturado en una forma altamente recalcitrante al tiempo que se mejora la calidad del suelo.

Los procedimientos quirúrgicos que envuelven la rehabilitación de la región maxilofacial requieren frecuentemente el uso de injertos para la reconstrucción de de deformidades congénitas o adquiridas. De esta forma, defectos óseos pueden clasificarse como críticos o no críticos. En esta investigación fueron utilizados 6 canes machos realizando 2 defectos bicorticales de 8mm de diámetro en la calota craneal de cada animal; el relleno de las cavidades se realizo como grupo 1 con coagulo sanguíneo y grupo 2 con hueso autógeno en partículas. A través de un an análisis histológico descriptivo se observo en el periodo de tres semanas de sacrificio que el grupo 2 fue el único en presentar regiones de aposición de nuevo tejido óseo.

Autores: George, Alexandra.
L'augmentation croissante de la demande en eau, liée à la croissance et aux besoins accrus de la population fait peser sur cette ressource, qualifiée de «pétrole bleu», une pression de plus en plus grande, notamment sur son utilisation comme bien commun. C'est ce qui ressort du nouveau rapport des Nations Unies intitulé « L'eau dans un monde qui change», présenté à New York au siège des Nations Unies le 12 mars 2009. Parmi les objectifs énoncés dans ce rapport, il est préconisé une meilleure gestion de l'eau, pour remédier aux pénuries auxquelles nous sommes confrontés. En effet, la question de la gestion quantitative de l'eau est tout aussi fondamentale que la question de sa qualité. Cette problématique fait l'objet d'une étude qui s'inscrit dans le cadre...

The aim of this study is to analyze alternative options of a Common Agricultural Policy  (CAP) after 2013 and their consequences for farms in Austria. Projections about the  development of agricultural markets are based on OECD-FAO forecasts. Using these  price projections, three alternative policy scenarios have been developed for a period  beyond 2013, which are compared with a baseline scenario. The three policy scenarios  encompass different assumptions on specific measures in the dairy sector and  higher modulation (13% versus the existing rate of 5%) as well as budget cuts in the  first pillar of CAP of 30% and 50%, respectively. All the scenarios have been analyzed  with the farm optimization system FAMOS, which differentiates among 5.796 typical...

Analysing the South African table grape industry within a partial equilibrium framework
Provedor de dados: 31
Autores: Reynolds,   Sanri.
This paper presents a partial equilibrium model for the South African table grape industry, focussing on the fresh market segments. The model is a dynamic recursive model solving various equations simultaneously, reaching a state of equilibrium once total production equals total demand and equilibrium is established in the export- and domestic market for fresh grapes. Results over the next eight years are presented in the form of a baseline outlook and two “what if” questions. Answering these questions quantifies the sensitivity of the export price to changes in demand and supply. The model is housed and maintained in the Bureau for Food and Agricultural Policy at the Western Cape Department of Agriculture and Universities of Pretoria and Stellenbosch.

Analysis and optimization regarding the activity of a Hungarian Pig Sales and Purchase Cooperation
Provedor de dados: 31
Autores: Balogh,   Peter; Ertsey,   Imre; Fenyves,   Veronika; Nagy,   Lajos.
In many ways, the Hungarian pork chain faces considerable disadvantages when compared to the situation in competing countries. In countries endowed with a modern meat chain, heavy concentration is the rule, but in Hungary decentralization still prevails, although thankfully the chain is not disintegrating even further. In our research we used the operation of co-operatives as a model in terms of a generalized network problem. The model allows the quantification of the number of pigs from given farms to slaughterhouses, the maximum sales revenue, the delivery threshold prices, and an analysis of the impact co-operative members exert on sales revenues.

Analysis and visualization of the glass eel behavior (Anguilla anguilla) in the Adour estuary and estimate of its upstream migration speed
Provedor de dados: 5
Autores: Prouzet, Patrick; Odunlami, Marc; Duquesne, Elise; Boussouar, Ahmed.
The studies carried out on the Adour estuary on the migration of glass eels lead to the characterisation of their swimming behavior. Individuals migrate passively with the flood tide current behind the dynamic tide front, and their movements into the water column are linked to the surrounding luminosity and water turbidity. A numerical model was built from observations gathered on glass eel densities during scientific surveys. It uses the outputs of a hydrodynamic model accounting for the variations in the river flow and tide coefficient. It allows the simulation of the displacement of a particle in the longitudinal axis of the estuary. The variation of the vertical movements through the water column takes into account the cloud cover, the moon phases, the...

Autores: Robledo,Renato; Piras,Ignazio; Beggs,William; Calò,Carla.
The genotypes of 31 autosomal short tandem repeat loci in the population of Carloforte were analyzed, these representing a linguistic and genetic isolate located on the island of Sardinia (Italy). The markers span the entire length of chromosomes 19, 20, 21 and 22. Allele frequencies and statistical parameters were presented for all loci. Observed heterozygosity ranged from 0.279 to 0.884, and polymorphism information content from 0.552 to 0.886. All but two loci showed Hardy-Weinberg equilibrium after Bonferroni correction. The 31 short tandem repeat loci examined in the present work provide additional data on the genetic structure of the Carloforte population.

Evolution of Earth&amp;#x2019;s climate system over the past 800,000 years represents a complex process with successions of uneven glacial and interglacial periods. The length, amplitudes, and development of each climate cycle depend on a number of different factors, including the orbital parameters attributed to insolation and the complex responses of the Earth system to solar radiation primarily through the amplification by Earth&amp;#x2019;s albedo and greenhouse gas and secondarily through a system of heat reservoirs, such as ice sheet and deep ocean, distributed throughout our planet.

Autores: Díaz-Matallana,Marcela; Schuler-García,Ingrid; Ruiz-García,Manuel; Hodson de Jaramillo,Elizabeth.
Currently in Colombia, there are only records of morph-agronomic characterizations of Mangifera indica cvar. Hilacha; molecular studies on this mango variety have not been carried out. The aim of this work was to identify the genetic diversity of six populations of mango Hilacha by RAPDs markers, as a fundamental base for breeding programs, conservation and selection of promissory materials for the fruit industry at the national level. From 60 primers evaluated in the populations, five primers were selected and were launched in the six populations. Polymorphic bands of RAPDs were transformed into binary matrices, which were then processed with NTSYS-PC, POPGENE and TFPGA softwares. The overall genetic diversity, H T = 0.468 ± 0.0016, is very similar to the...

BACKGROUND:  Endocrine disruptors include plasticizers, pesticides, detergents and pharmaceuticals.  Turbot and other flatfish are used to characterize the presence of chemicals in the marine environment.  Unfortunately, there are relatively few genes of turbot and other flatfish in GenBank, which limits the use of molecular tools such as microarrays and qRT-PCR to study disruption of endocrine responses in sentinel fish captured by regulatory agencies.&amp;#xd;&amp;#xa;OBJECTIVES:  A multi-gene cross species microarray was fabricated as a diagnostic tool to screen the effects of environmental chemicals in fish, for which there is minimal genomic information.  The array included genes that are involved in the actions of adrenal and sex steroids, thyroid...

Analysis of Environmental and Economic Efficiency: Application of the Overseer model and simulated data
Provedor de dados: 31
Autores: Ramilan,   Thiagarajah; Scrimgeour,   Frank G.; Marsh,   Dan.
New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

Analysis of feral pig (Sus scrofa) movement in a Hawaiian forest ecosystem using GPS satellite collars
Provedor de dados: 17
Autores: Lasha-Lynn  H. Salbosa; Dr. Christopher A. Lepczyk.
The ecosystem altering impacts of feral pigs have been widely documented around the world.  However, a general framework for their control and management has been lacking, especially in island ecosystems.  One reason for this lack of management is that we have little knowledge of how pigs move through different island ecosystems, especially ones that are topographically challenging such as Hawai&amp;#x201b;i.  With recent advances in telemetry and movement modeling, it is now becoming practical to understand where these large introduced animals are moving and how they are using habitat.  Hence, the primary goal of this study is to understand feral pig movement in terms of terrain, slope restrictions, and distance traveled beyond a natal site, within an...

Analysis of Marketing Margins under Food Recalls and BSE Outbreaks in the U.S. Beef  Industry
Provedor de dados: 31
Autores: Dhoubhadel,   Sunil P.; Castillo,   Sergio C.; Capps,   Oral, Jr.
It is generally observed that whenever there are cases of disease outbreaks or food recalls, there is a concomitant decline in commodity prices.  However, it is still not clear what happens to price spreads among affected agents in the marketing chain.  To shed light on this issue, we estimate the collective impact of Bovine Spongiform Encephalopathy (BSE) and food recalls on marketing margins associated with the U.S. beef industry over time.  In previous research, the effects of these variables on the market demand of meat were estimated separately.  By including these variables together in the same model specification we avoid the possibility of confounding their effects, and we are in position to obtain more precise estimates of elasticities of price...

Analysis of Mercury-Rich plants and mine tailings using the Hydride-Generation AAS method
Provedor de dados: 52
Autores: Moreno,Fábio Netto; Anderson,Christopher; Stewart,Robert; Robinson,Brett.
A hydride-generation atomic absorption spectroscopy (AAS) method was developed for the analysis of total Hg in liquid matrices of mercury-rich plants and mine tailings samples. The detection limit for this method was as low as 11.4 ng/mL. The reproducibility of the mercury signals (in terms of relative standard deviation) was 4.6%. Accuracy of the method was verified by analyses of deionised water samples spiked with HgCl2 and HgNO3. Recovery values for total mercury ranged from 88.5 to 94.3% for both mercury species added. An external certified laboratory validated the analytical method with a maximum discrepancy of 15 %. Optimal analytical response of the equipment for Hg analysis of plant samples was achieved when the sample volume added to the reaction...

Analysis of poverty and its covariates among smallholder farmers in the eastern Hararghe highlands of Ethiopia
Provedor de dados: 31
Autores: Bogale,   Ayalneh; Korf,   Benedikt.
This paper analyses the extent and determinants of rural household poverty in the eastern highlands of Ethiopia. We study 216 households using a household consumption expenditure approach. We are particularly interested in the effects of location-specific and institutional factors (networks) in determining the probability of being poor. Our findings suggest that poverty is location-specific, depends on access to irrigated land (not land per se) and access to non-farm income. Results also indicate that household wellbeing is negatively affected by household size, and positively affected by age of household head. Involvement in governance, social and production related networks is also found to be strongly associated with the probability of a household be...

Analysis of profitability and risk in new agriculture in a Himalayan watershed by using dynamic non-linear programming model
Provedor de dados: 31
Autores: Sharma,   Rakesh Kumar; Sankhayan,   Prem Lall; Singh,   Ranveer.
Cropping pattern in the Himalayan region of India has undergone a significant change in the recent past. Introduction of horticultural crops of vegetables, fruits and flowers have led to more intensive agriculture. Such a change, resulting in higher incomes and improvements of the overall living conditions has, however, been accompanied with increased income risk. This emphasises a need for proper analysis of the cropping pattern, at an appropriate scale, such as, a micro watershed. This was achieved by constructing a dynamic non-linear programming model incorporating appropriate objective function, constraints and crop and livestock activity budgets along with risk component present in the gross returns. The model was then solved under alternate policy...

Because wines (of grapes) were excluded from the scope of EC Regulation 2092/91 (annex 6, concerning processing organic food, does not apply to wine) concerning organic farming, up till now there is no legal definition for organic wines at European level, but only rules for organic grapes production. This project: ORWINE, is aiming to help the UE commission to develop a legislative framework for the transformation of organic grapes into organic wine. This would allow replacing the current definition “wine made from organically grown grapes” by “organic wines”. One of the first tasks of this project is a description of the regulatory framework applied to EU organic wine-making. Legal public and private standards for wine processing are taken in...

The CC chemokine receptor 5 (CCR5) molecule is an important co-receptor for HIV. The effect of the CCR5*D32 allele in susceptibility to HIV infection and AIDS disease is well known. Other alleles than CCR5*D32 have not been analysed before, neither in Amerindians nor in the majority of the populations all over the world. We investigated the distribution of the CCR5 coding region alleles in South Brazil and noticed a high CCR5*D32 frequency in the Euro-Brazilian population of the Paraná State (9.3%), which is the highest thus far reported for Latin America. The D32 frequency is even higher among the Euro-Brazilian Mennonites (14.2%). This allele is uncommon in Afro-Brazilians (2.0%), rare in the Guarani Amerindians (0.4%) and absent in the Kaingang...

In colonies of Melipona scutellaris Latreille, 1811 workers can be found with four ganglion nerve cells, a morphological characteristic of the queen. It is hypothesized that these workers, called intercastes, or phenocopies, are phenotypically-like workers, but genotypically identical to queens due to this specific trait. Workers with the same number of ganglion as queens seem to be intercastes between queens and workers. Our objective was to analyze the mRNA pro files of workers, queens, and intercastes of M. scutellaris through DDRT-PCR. Three hundred (300) pupae with white eyes were collected and externally identified according to the number of abdominal nerve ganglions: workers (5 ganglions), queens (4 ganglions) and intercastes (4 ganglions).

Several studies revealed a similar down-regulation of telomeric repeat binding factor 1 (TRF1) in tumors. We have previously reported the TRFl expression levels were down-regulation in non-small cell lung cancer (NSCLC). The regulation of TRFl localization is proposed to be important for the function and expression. The nuclear localization signal (NLS) and nuclear export signal (NES) are often important clues to localization of protein. The objective of the present study was to investigate the NLS and NES of TRFl in NSCLC patients. Thirty (30) patients with NSCLCs had undergone radical operations in The First Affiliated Hospital, College of Medicine, Zhejiang University. DNA sequences of NLSs and NESs were amplified by PCR.

After great improvements in energy efficiency in the 1970’s, Japan has made little progress in reducing energy consumption since 1990, the base year for the Kyoto Protocol.  This study is motivated by the recent growing demands among policy makers to find all possibilities for saving energy.  To make informed decisions on how to save energy, policy makers need detailed information on energy consumption structures within each jurisdiction. First, in this article, I decompose national level energy intensity into efficiency and activity effects with the Fisher Ideal index, and then estimate regressions on prefecture level residential electricity demand between 1990 and 2003.  It is found that national level energy intensity declined by seventy three percent...

Analysis of the distribution of organic farming and its determinants is a major challenge for the construction of scenarios related to the evolution of organic farming that take the set of factors that limit or facilitate conversions and their sustainability into account. In order to support different development scenarios for organic farming in view of environmental and marketing challenges, an econometric and geostatistic study was initiated in the PACA region. The approach consists of three stages. The first stage involves the construction, over a 20-year period, of a longitudinal spatial database concerning certified organic producers and distributors. This database is georeferenced at the plot level. It will then be necessary to statistically analyse...

We use Sperber's intermediairies and the firm theory to analyze the rural socialized service organizations. By studying the case of the melon association in Beihe Village of Uqiao Township in Beijing, we find that the basic existing objective of this association is to save transaction cost. The theoretical research and case analysis results show that the dispersed peasants are unable to solve the contradiction between small-scale production and large-scale market. However, the rural socialized service organizations, the purpose of which is to serve the benefit of the peasants, can save the transaction cost of peasants and safeguard the economic interests of the peasants.

Provedor de dados: 21
Autores: LAMINE, C.; MEYNARD, J.-M.; PERROT, N.; BELLON, S.
Interdisciplinary approaches developed concerning the conversion to organic farming show that the types of conversion trajectories can be differentiated on the basis of the progression of crop protection changes within a larger framework where relationships to other “objects” are transformed – the soil, products, rotations, work organisation, marketing, social networks and knowledge acquisition. In the case of integrated plant production, the extent of changes depends on the degree of recomposition of agronomic practices. This transition implies major knowledge acquisition that relies on the support and contribution of advisors and on the group dynamics that develop within a group of farmers. Transitions towards integrated crop protection are, by their...

Autores: Montenegro,G; Gómez,M; Casaubon,G; Belancic,A; Mujica,AM; Peña,RC.
Three unifloral honeys were identified by the pronounced presence of specific compounds by means of sensorial analysis and SPME-GC-MS. Smoky and resinous (&amp;#8216;propolis') odors characterized unifloral "quillay" (Quillaja saponaria) honey. "Corontillo" (Escallonia pulverulenta) honey was characterized by caramel and vanillin aromas, and "ulmo" (Eucryphia cordifolia) honey by having an anise scent with a floral jasmine note. Safranal was a useful marker for "corontillo" honey. Isophorone and cetoisophorone were the distinctive compounds of unifloral "ulmo" honey. In "quillay" honeys, megastigmatrienone, 2-p-hydroxyphenylalcohol and minor quantities of &amp;#946;-pinene and linalool oxide were correlated with their sensory properties such as resinous.

Analyzing Drivers of World Food Prices: Weather, Growth, and Biofuels
Provedor de dados: 31
Autores: Saunders,   Caroline M.; Kaye-Blake,   William; Cagatay,   Selim.
The recent rise of food cost in world markets has accelerated the research examining the underlying factors for this rise. The present research investigated the separate and combined impacts of three factors thought to contribute to the price rise: adverse weather events, strong and sustained growth in high populated countries, and increased biofuels production. The research further analysed the effects of these price rises on consumption expenditures in Brazil, China and India. Analyses were carried out using a partial equilibrium trade model with a focus on the 2004 to 2007 period. The modelling suggests that the most important factor behind the price rise depends on the commodity, with maize/corn, oilseeds, and sugar most affected by biofuels, while...

Analyzing Effects of the U.S. Duties on Canadian Hard Red Spring Wheat
Provedor de dados: 31
Autores: Baek,   Jungho; Mattson,   Jeremy W.; Koo,   Won W.
Since the United States imposed antidumping and countervailing duties totaling 14.16 percent on imports of Canadian hard red spring (HRS) wheat, Canadian exports to the United States have nearly stopped. This study examines the impact of the decreased HRS wheat imports from Canada on U.S. wheat prices and producer income. To measure the impacts of the U.S. duties accurately, special attention is paid to issues related to substitutability between HRS and hard red winter (HRW) wheat and third-country effects. Results suggest that the substantial decline in Canadian HRS wheat exports to the United States has increased U.S. HRS and HRW wheat prices and thus farm income.

Analyzing Factors Affecting U.S. Food Price Inflation.
Provedor de dados: 31
Autores: Baek,   Jungho; Koo,   Won W.
Since the summer of 2007, U.S. food price has increased dramatically. Given public anxiety over fast-rising food prices in recent years, this paper attempts to analyze the effects of market factors ─ prices of energy and agricultural commodities and exchange rate ─ on U.S. food prices using a co-integration analysis. Results show that the agricultural commodity price and exchange rate play key roles in determining the short- and long-run movement of U.S. food prices. It is also found that in recent years, the energy price has been a significant factor affecting U.S. food prices in the long-run, but has little effect in the short-run. This implies the strong long-run linkage between energy and agricultural markets has emerged through production of...

Analyzing FSA Direct Loan Borrower Payback Histories:  Predictors of Financial Improvement and Loan Servicing Actions
Provedor de dados: 31
Autores: Landerito,   Aiko O.; Dixon,   Bruce L.; Ahrendsen,   Bruce L.; Hamm,   Sandra J.; Danforth,   Diana M.
Classical and count data regression models are estimated to predict improvement in three key financial indicators—net worth, debt-to-asset ratio and current ratio—as well as the number of loan restructurings and delinquencies.  Data consist of Farm Service Agency direct loans originated in fiscal years 1994-1996.  Models to predict outcomes vary by loan type.  Models explaining variation in the financial measures have modest explanatory power but initial levels of debt-to-asset ratio and current ratio are significant in explaining changes in debt-to-asset ratios and current ratios, respectively.  Models explaining number of restructurings and delinquencies for operating loans have satisfactory explanatory power.  Increasing crop revenues to total farm...

Analyzing one-way experiments: a piece of cake of a pain in the neck?
Provedor de dados: 63
Autores: Kozak,Marcin.
Statistics may be intricate. In practical data analysis many researchers stick to the most common methods, not even trying to find out whether these methods are appropriate for their data and whether other methods might be more useful. In this paper I attempt to show that when analyzing even simple one-way factorial experiments, a lot of issues need to be considered. A classical method to analyze such data is the analysis of variance, quite likely the most often used statistical method in agricultural, biological, ecological and environmental studies. I suspect this is why this method is quite often applied inappropriately: since the method is that common, it does not require too much consideration-this is how some may think. An incorrect analysis may...

Analyzing supply response of fruit tree products in Tunisia: The case of peaches
Provedor de dados: 31
Autores: Laajimi,   Abderraouf; Guesmi,   Anis; Mahfoudhi,   A.; Dhehibi,   Boubaker.
In Tunisia, peaches have a significant place in the fruit tree sector. Planted areas have  been expanding ever since the eighties as a result of irrigation water extension and the  use of better yielding varieties. These factors resulted in high production levels and fruit exports  thereof.  However,  important  seasonal  and  annual  variation  of  fruit  supplies continues to characterize prices at both wholesale and consumption levels. To study the  response  of  peach  production  an  econometric  model  was  developed. Modelling  was carried out in two stages. First area variation was explained through new plantings and removals and second yield variation was analyzed. The methodological approach followed takes into account the characteristics and...

Autores: Fernandez-Solari,J.; Prestifilippo,J.P.; Vissio,P.; Ehrhart-Bornstein,M.; Bornstein,S.R.; Rettori,V.; Elverdin,J.C.
Our objective was to determine the effect of arachidonylethanolamide (anandamide, AEA) injected intracerebroventricularly (icv) into the lateral ventricle of the rat brain on submandibular gland (SMG) salivary secretion. Parasympathetic decentralization (PSD) produced by cutting the chorda tympani nerve strongly inhibited methacholine (MC)-induced salivary secretion while sympathetic denervation (SD) produced by removing the superior cervical ganglia reduced it slightly. Also, AEA (50 ng/5 µL, icv) significantly decreased MC-induced salivary secretion in intact rats (MC 1 µg/kg: control (C), 5.3 ± 0.6 vs AEA, 2.7 ± 0.6 mg; MC 3 µg/kg: C, 17.6 ± 1.0 vs AEA, 8.7 ± 0.9 mg; MC 10 µg/kg: C, 37.4 ± 1.2 vs AEA, 22.9 ± 2.6 mg). However, AEA did not alter the...

Anatomical and Clinical Considerations of the Pectoralis Tertius Muscle in Man
Provedor de dados: 77
Autores: del Sol,Mariano; Vásquez,Bélgica.
The anatomical variation of the major pectoral muscles is infrequent, namely the agenesis of the pectoralis major muscle due to the morpho-functional alterations it causes. On the other hand, he presence of -supernumerary - pectoral muscles is not common and its physiological, clinical or surgical importance will depend on the stage of its development. The important aspect is that these muscles, while crossing the anterior wall of the axila and inserting in the humerus, may confuse or difficult surgical access to the content of the axillary fossa. Pectoralis tertius muscles were found in two dissected cadavers at the Topographic Anatomy of the Faculty of Medicine of the Universidad de La Frontera, Chile. These muscles were bilateral and independent of the...

Anatomical and developmental aspects of leaf galls induced by Schizomyia macrocapillata Maia (Diptera: Cecidomyiidae) on Bauhinia brevipes Vogel (Fabaceae)
Provedor de dados: 88
Autores: Sá,Camila Emiliane Mendes de; Silveira,Fernando A. O.; Santos,Jean C.; Isaias,Rosy Mary dos Santos; Fernandes,G. Wilson.
Samples of healthy leaves and galls induced by Schizomyia macrocapillata Maia on Bauhinia brevipes Vogel were submitted to routine techniques to investigate gall anatomy and development. Pouch galls are induced on the abaxial surface of unfolded immature leaves, and become spheroid with long reddish hairs covering their external surface. Galls occur isolated or coalesce when in larger numbers. Gall development was divided into six phases: 1) initiation; 2) tissue re-arrangement; 3) tissue differentiation; 4) maturation; 5) growth phase; and 6) dehiscence. This last phase corresponds to gall senescence, which takes place just after the larva exits the chamber to pupate. An important developmental phase of tissue reorientation was recorded after the...

Autores: Méndez Rebolledo,Guillermo; Coronado Gallardo,Roberto; Suazo Galdames,Iván.
The fibularis longus muscle (FLM) has an important role in the movement of eversion of the foot and in maintaining the plantar arch. The electrostimulation procedures seek to maintain muscle trophism, increase strength and endurance, and are frequently used in physiotherapy, for which the clinician needs to know the location of the motor points of the FLM. Therefore, the purpose of this study was to determine the number and distribution of motor points of the FLM and relate them to observable parameters in the surface anatomy. Ten formalin-preserved limbs were used, and the lateral regions of the leg were dissected in detail. In all the cases, the muscle presented three fascicular patterns, the superior and anteroinferior fascicles presented two motor...

Variations in the trajectory of the brachiocephalic trunk and the common carotid artery predispose to disorders which might be critical in a tracheotomy and/or surgeries. Dissection of 110 formol fixed adult cadavers, both sexes, were performed to increase the anatomic knowledge of the neck vessels and its variations. Cadavers were from the Laboratory of Descriptive and Topographic Anatomy of the Federal University of São Paulo- Paulista Medical School- UNIFESP-EPM. In 109 of these cadavers no variations were found while in one (0.9 %) it was possible to observe a variation in the trajectory of the brachiocephalic trunk and in the right common carotid artery.

Autores: Coriolano,M. G. W. S; Lins,O. G; Amorim,M. J. A. A. L; Amorim,A. A. Jr.
The anconeus is a small muscle situated at the elbow. Although the anconeus is active during elbow extension its importance for the movement is probably small. It could work as an elbow stabilizer. The object of this study was to investigate some anatomic and architectural characteristics of the anconeus, in the hope of shedding light on its function. We studied twenty adult cadaveric specimens. The anconeus originates by the lateral epicondyle of the humerus and inserts along the proximal ulna. The superficial shape of the anconeus is triangular. Tridimensionally the anconeus resembles a hemisected rectangular-based pyramid, with the base at the ulna and apex at the lateral epicondyle. The muscle fibers arise obliquely from the tendinous expansion and...

Provedor de dados: 77
Autores: Malashetty,Vijaykumar B; Sonar,A; Patil,Saraswati B.
Calotes versicolor, collected during peak breeding and nonbreeding season were used for the study of anatomy and histophysiology of pituitary gland. In C. versicolor the pituitary gland is small compact mass attached to the hypothalamus by a delicate stalk. It is of two basic units, adenohypophysis and neurohypophysis. The adenohypophysis includes pars distalis (PD) and pars intermedia (PI). The pars tuberalis (PT) which is usually reduced in reptiles, is absent in C. versicolor. The neurohypophysis is composed of median eminence (MI) and neural lobe or pars nervosa (PN). The anterior PD is rich acidophils than the posterior PD during breeding season. These cells are differentiated as A1 and A2 cells. The A1 cells are erythrosinophilic and stained purple...

Autores: Rodrigues,Antonio de Castro; Andreo,Jesus Carlos; Menezes,Laura de Freitas; Chinellato,Tatiana Pimentel; Rosa Júnior,Geraldo Marco.
Facial palsy, parotid diseases and others are a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. Parotid gland diseases also are very common occurrence. In this particular case, the knowledge of surgical anatomy of the facial nerve and its correlations with the parotid gland is very important for an adequate preservation in the cases of surgery of benign and malignant diseases of the parotid gland. Although the surgical anatomy of the facial nerve has been well documented, the concept of surgical treatment for parotid tumors, facial palsy (neurorraphy techniques) and submandibular surgical approach are rarely challenged now.

Anatomy, ultrastructure and secretion of Hibiscus pernambucensis Arruda (Malvaceae) extrafloral nectary
Provedor de dados: 88
Autores: Rocha,Joecildo Francisco; Machado,Silvia Rodrigues.
This paper reports on the extrafloral nectary (EFN) of Hibiscus pernambucensis, a native shrub species occurring in mangrove and restinga along Brazil's coastline. EFNs occur as furrows with a protuberant border on the abaxial surface veins of the leaf blade. Each nectary consists of numerous secretory multicellular trichomes, epidermal cells in palisade-like arrangements and non-vascularized parenchyma tissue. Nectar secretion is prolonged, since secretion starts in very young leaves and remains up to completely expanded leaves. Reduced sugars, lipids, and proteins were histochemically detected in all the nectary cells; phenolic substances were detected in the vacuoles of the epidermal palisade cells and in some secretory trichome cells. The secretory...

Anbau der Blauen Lupine (Lupinus angustifolius) mit  unterschiedlichen Reihenabständen und Bewertung der  Futterqualität mittels NIRS
Provedor de dados: 21
Autores: Böhm, Herwart; Aulrich, Karen.
Blue lupins have become more important in animal feeding due to increasing organic  animal husbandry. They have a low starch content, a high protein content and the best  protein quality of the home-grown grain legumes. The feed quality of blue lupins can  be analysed by NIRS very quickly and cost-efficiently. Weed infestation in pure stands  of blue lupin is often a problem. Mixed cropping systems are a good alternative for  weed suppression, but the yield percentage of blue lupins in mixed cultivation is low.  Weed infestation can be reduced by hoeing. Therefore the cultivation of blue lupins  with the possibility of hoeing in the wider row distances (25.0 cm, 37.5 cm), were  compared to 12.5 cm row distance (only currying). Field experiments were...

Autores: Böhm, Herwart.
Der Beitrag gibt einen Überblick über den Anbauumfang von Körnerleguminosen in Deutschland und speziell im Ökologischen Landbau. Hierbei wird deutlich, dass der Körnerleguminosenanbau seit Jahren stark rückläufig ist. Der Anteil der ökologisch angebauten Körnerleguminosen an der Gesamtfläche steigt dabei kontinuierlich an und betrug im Jahr 2007 bei Ackerbohnen 47 % bzw. bei Lupinen 35 %. Deutlich wird jedoch, dass der Körnerleguminosenanbau im Ökologischen Landbau hinsichtlich des prozentualen Anteils an der ökologisch bewirtschafteten Ackerfläche seit Jahren ebenfalls stark rückläufig ist und in 2007 nur noch 6,2 % der Öko-Ackerfläche einnahm.

Androgen Receptor and Vasopressin Receptor (AVPR1a) Genetic Polymorphisms are not associated with Marital Status or Fertility among Ariaal Men of Northern Kenya
Provedor de dados: 17
Autores: Peter B. Gray; Dan T. A. Eisenberg; Benjamin C. Campbell.
A growing body of scholarship implicates testosterone and vasopressin in male reproductive behavior, including in humans. Since hormones exert their effects through their respective receptors, an open question has been whether genetic polymorphisms in the androgen receptor and vasopressin 1a receptor (AVPR1a) impact human male social behavior. Here, we sought to test for associations between polymorphisms in the coding region of the androgen receptor and promoter region of AVPR1a in relation to marital status and fertility among pastoralist Ariaal men of northern Kenya. None of the three polymorphisms were related to marital status (single, monogamously married, polygynously married) or fertility (number of current living children). We discuss these null...

Os cágados apresentam fisiologia e morfologia únicas, que se diferenciam em muitos aspectos dos mamíferos. Por isso, a monitoração do paciente durante um processo anestésico ou sedativo deve ser realizada, porque dosagens e drogas com resultados benéficos em mamíferos têm-se mostrado inadequados para estas espécies. Foram utilizados dez exemplares de Phrynops geoffroanus, provenientes do rio Uberabinha, no município de Uberlândia, Estado de Minas Gerais (licença RAN/IBAMA nº 035/2006), os quais foram anestesiados com o protocolo midazolan 2 mg kg-1 IM-1 e propofol 10 mg kg-1 IV-1. Os batimentos cardíacos dos exemplares foram monitorados com o aparelho Doppler Vascular Eletrônico nos tempos 0’, 10’, 30’, 60’, 120’ e 180’ pós-anestésico e, durante o período...

Anestesia do pirarucu por aspersão direta nas brânquias do eugenol em solução aquosa
Provedor de dados: 65
Autores: Honczaryk,Alexandre; Inoue,Luís Antonio Kioshi Aoki.
O pirarucu (Arapaima gigas) é um peixe que vem ganhando importância cada vez maior na piscicultura comercial na Amazônia. No entanto, por ser um animal de grande porte, no campo, é comum o relato de acidentes envolvendo pancadas violentas em técnicos durante o manejo. Desse modo, é imperativa a anestesia desses animais. Todavia, para a espécie em discussão, a realização de banhos anestésicos, muitas vezes, não é possível devido ao tamanho do animal e ao risco de afogamento do peixe pulmonado. O presente trabalho avaliou de maneira prática a viabilidade do eugenol como anestésico para o pirarucu por aspersão direta nas brânquias. Para tanto, três animais jovens foram submetidos à aspersão de eugenol nas brânquias em concentração de 30mg L-1 e dois na...

Anesthesia in Pacific oyster, Crassostrea gigas
Provedor de dados: 5
Autores: Suquet, Marc; De Kermoysan, Goulwen; Araya, Ricardo Gonzalez; Queau, Isabelle; Lebrun, Luc; Le Souchu, Pierrick; Mingant, Christian.
A reliable anaesthesia and sampling protocol for Pacific oysters will enable experiments to be conducted without sacrificing animals and will facilitate successive sampling of individuals for gametogenesis studies. As no such techniques were available for Crassostrea gigas, the present study aimed to define suitable anaesthetic conditions for use with this species. Three groups of ten oysters (mean weight +/- SD, 32.1 +/- 9.0 g) were anaesthetised in 5 L containers. Among different chemicals: benzocaine, eugenol and three different types of magnesium chloride (a laboratory one Flucka (R) - and two designed for agriculture - DEUSA International (R) and Dead SeaWorks (R)) and concentrations tested, one laboratory (concentration: 72 g L-1) and one...

Anfälligkeit neuer Kartoffelsorten gegenüber Kraut- und Knollenfäule (Phytophthora infestans) und Rhizoctonia (Rhizoctonia solani) – entscheidend für Ertrags- und Qualitätssicherung im biologischen Anbau
Provedor de dados: 21
Autores: Dupuis, B; Reust, W; Schwärzel, R; Hebeisen, Th; Ballmer, Th; Musa, T.
Potato is affected by numerous diseases. Among those diseases, late blight (Phytophthora infestans) and rhizoctonia (Rhizoctonia solani) have a strong economic impact. Organic farming doesn’t have efficient protection products to control those diseases and to guarantee yield and production quality. Furthermore, we observe that organic food chain propose the same cultivars as the traditional food chain and those cultivars are generally susceptible to late blight. Regarding to the trials managed to propose new cultivars to Swiss cultivars recommendation list, there are numerous new cultivars with interesting resistance profile. Among 141 cultivars tested, 30 could be proposed to the organic food chain. Indeed, those cultivars are less susceptible to late...

Anfälligkeit von Leguminosen gegenüber Meloidogyne hapla
Provedor de dados: 21
Autores: Reents, Dr. H. J.; Egerer, Johanna; Hermann, A.
Green manure legumes are a necessary element of organic crop rotations. However,  they are able to propagate nematodes especially Meloidogyne and Paratylenchus  species. The results of a pot experiment showed that plant species of the genera  Pisum, Vicia, Trifolium had a higher propagation rate of Meloidogyne hapla than salad  Latuca sativa while plant species of the genera Medicago and Melilotus were less  susceptible to infestation of nematodes. It is concluded that crop rotation management  especially in vegetable production has to consider the different susceptibility of the  legumes and further research has to test more species and varieties.

Autores: Zeller, Dr. Heiko; Häring, Prof. Dr. Anna Maria; Utke, Norman.
Although the demand for organic products in Germany continues to increase, there is  still a gap in supplied quantities. This issue is also valid for organic potatoes. The  paper presents an estimate of the price elasticity of supply for organic potatoes in  Germany using a Nerlovian model, where the output is a function of expected price,  output in terms of area adjustment and further exogenous variables. The results indicate  a short-run elasticity of 0.22, suggesting that organic potato farmers are highly  unresponsive to price changes on a temporary basis. However, in the long-run farmers  react highly responsive to price changes with an elasticity of 1.86. It shows that  price incentives can be effective in promoting organic potato production,...

Angiotensin II stimulates MCP-1 production in rat glomerular endothelial cells via NAD(P)H oxidase-dependent nuclear factor-kappa B signaling
Provedor de dados: 56
Autores: Pan,Q.; Yang,X.-H.; Cheng,Y.-X.
Angiotensin II (Ang II) plays a crucial role in the pathogenesis of renal diseases. The objective of the present study was to investigate the possible inflammatory effect of Ang II on glomerular endothelial cells and the underlying mechanism. We isolated and characterized primary cultures of rat glomerular endothelial cells (GECs) and observed that Ang II induced the synthesis of monocyte chemoattractant protein-1 (MCP-1) in GECs as demonstrated by Western blot. Ang II stimulation, at concentrations ranging from 0.1 to 10 µm, of rat GECs induced a rapid increase in the generation of reactive oxygen species as indicated by laser fluoroscopy. The level of p47phox protein, an NAD(P)H oxidase subunit, was also increased by Ang II treatment. These effects of...

Quantitative and qualitative relation between beach characteristic and number of observed nests of Green turtle Chelonia mydas at Cayo Largo is shown. The nest quantification was carried out by patrolling and direct count in reproduction season for this species (June-September) in period 2002-2006. A total of 7 beaches were identified with sands strips between 5 and 50 m of wide and between 70 and 4 060 m of length. Annual nesting between 1 114 and 1 866 nests was registered. Maximum number of nests per beaches was 837 nests at Mal Tiempo which also was the maximum value of density (360 nest/km). A positive trend to increase for all key was observed. Results indicate Cayo Largo as main site of nesting of green turtle in Cuba and one of the most important...

Animal emergence during Snowball Earths by thermosynthesis in submarine hydrothermal vents
Provedor de dados: 17
Autores: Anthonie W. J. Muller.
Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^. This emergence of the animals (metazoans: multicellular animals) has therefore attracted much attention^2-5^. Two decades ago it was reported that extensive global glaciations (Snowball Earths) preceded the emergence^6-7^. Here we causally relate the emergence and the glaciations by invoking benthic sessile^8-11^ thermosynthesizing^12-13^ protists that gained free energy as ATP while oscillating in the thermal gradient between a submarine hydrothermal vent^14^ and the ice-covered ocean. During a global glaciation their size increased from microscopic to macroscopic due to the selective advantage of a...

Provedor de dados: 17
Autores: Anthonie W. J. Muller.
Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^. This emergence of the animals (metazoans: multicellular animals) has therefore attracted much attention^2-5^. Two decades ago it was reported that extensive global glaciations (Snowball Earths) preceded the emergence^6-7^. Here we causally relate the emergence and the glaciations by invoking benthic sessile^8-11^ thermosynthesizing^12-13^ protists that gained free energy as ATP while oscillating in the thermal gradient between a submarine hydrothermal vent^14^ and the ice-covered ocean. During a global glaciation their size increased from microscopic to macroscopic due to the selective advantage of a...

Animal health strategies in organic and conventional meat sheep production
Provedor de dados: 21
Autores: NICOURT, C.; BENOIT, M.; LAIGNEL, G.; CABARET, J.
Sixteen meat sheep farms (nine conventional and seven organic) in the centre of France were surveyed to evaluate their economic and production performances (previous interviews) and their strategies related to animal health with particular attention to internal parasites (present interview on health strategies). The organic farms were surveyed in mid-September 2006 and the conventional ones in October 2007. Each interview (1½ or 2 h) included a visit of the farm (with the collection of faeces for evaluation of internal parasites), followed by an open discussion on sheep production and health problems, and parasitic infections, in particular. The discussion was recorded and then transcribed into a word processor file and analysed. The farmers agreed on the...

Autores: Fučić,A.; Stojkovic,R.; Katić,J.; Markovic,D.; Ferencic,Z.; Koršić,M.; Jazbec,A.M.; Gamulin,M.
Environmental xenoestrogens pose a significant health risk for all living organisms. There is growing evidence concerning the different susceptibility to xenoestrogens of developing and adult organisms, but little is known about their genotoxicity in pre-pubertal mammals. In the present study, we developed an animal model to test the sex- and age-specific genotoxicity of the synthetic estrogen diethylstilbestrol (DES) on the reticulocytes of 3-week-old pre-pubertal and 12-week-old adult BALB/CJ mice using the in vivo micronucleus (MN) assay. DES was administered intraperitoneally at doses of 0.05, 0.5, and 5 µg/kg for 3 days and animals were sampled 48, 72 and 96 h, and 2 weeks after exposure. Five animals were analyzed for each dose, sex, and age group....

Animal performance and carcass characteristics of growing Hereford bulls under insulated, uninsulated and outdoor housing conditions in Northern Finland
Provedor de dados: 21
Autores: Huuskonen, Arto; Tuomisto, Leena; Joki-Tokola, Erkki; Kauppinen, Risto.
The objective of the present study was to compare the performance of Hereford bulls in an insulated tie-stall, an uninsulated barn and a forest paddock in Northern Finland (Ruukki: 64°44’N, 25°15’E). In November 1999, thirty Hereford bulls (age 6.8±0.5 (mean±SD) months; live weight (LW) 285±35 kg) were divided into six groups of five animals according to their LW and the groups were randomly allotted to one of three treatments: tie-stall in an insulated barn (IB bulls, ten animals in individual stalls), pen in an uninsulated barn (UB bulls, 5 animals per pen, two pens) and forest paddock (PAD bulls, 5 animals per paddock, two paddocks). The experiment ended in October 2000, when the bulls were 18.3±0.5 months of age and 772±51 kg LW. During the entire...

Autores: Canto,Marcos Weber do; Bona Filho,Amadeu; Moraes,Aníbal de; Hoeschl,André Ricardo; Gasparino,Eliane.
Nitrogen (N) at 100, 200, 300, and 400 kg ha-1 was applied to Tanzania grass swards to evaluate the animal response and relationships between sward characteristics and the performance of young Nellore bulls (Bos indicus) under continuous stocking. A completely randomized experimental design was used with two replications between 11 November 2001 and 15 April 2002 when the sward heights were maintained at 60 cm by using different stocking rates. The average daily gain (ADG) (0.73 kg d-1) was not affected by N doses while the number of animal days ha-1 increased linearly from 515 to 1267. On the other hand, the linear increase in the animal yield was 399, 653, 755, and 895 kg ha-1 for N at 100, 200, 300, and 400 kg ha-1, respectively, while the ratio between...

“Animal Welfare” Practices along the Food Chain: How Does Negative and Positive Information Affect Consumers?
Provedor de dados: 31
Autores: Dentoni,   Domenico; Tonsor,   Glynn T.; Calantone,   Roger J.; Peterson,   H. Christopher.
Managing a global brand means developing its equity but also protecting it from global challenges (Shocker et al., 1994) and from the risk of negative shocks that may affect a brand (Okada and Rubstein, 1998), a multi-national company (Klein and Dawar, 2004) or a whole industry (Roehm and Tybout, 2006). Negative information shocks may arise because of sudden product-harm crises or scandals (Klein and Dawar, 2004; Roehm and Tybout, 2006), such as food-borne disease outbreaks or environmental violation practices. In these situations, providing positive brand information can mitigate the effect of negative information shocks on consumers’ brand evaluations and buying intentions (Smith and Vogt, 1995; Okada and Rubstein, 1998; Klein and Dawar, 2004; Roehm and...

Animals’ Health Control Efficiency in Northwest Portugal: A Two-stage DEA Approach
Provedor de dados: 31
Autores: Costa,   Leonardo; Oude Lansink,   Alfons G.J.M.; Silva,   Elvira.
A two-stage approach is employed to analyze the efficiency of cooperatives responsible for ruminants’ disease control (OPP) at the farm level in Northwest Portugal. In the first stage, Data Envelopment Analysis (DEA) is used to estimate and decompose input-based overall inefficiency for each OPP. The input-based inefficiency measures are generated using the directional input distance function. In the second stage, the inefficiency estimates are regressed on environmental and organizational factors in order to explain efficiency differentials. Despite substantial environmental differences, the empirical results indicate that most cooperatives can reduce costs by improving scale efficiency and pure technical efficiency.

Annotation of SBML Models Through Rule-Based Semantic Integration
Provedor de dados: 17
Autores: Allyson L. Lister; Phillip Lord; Matthew  Pocock; Anil Wipat.
*Motivation:* The creation of accurate quantitative Systems Biology Markup Language (SBML) models is a time-intensive, manual process often complicated by the many data sources and formats required to annotate even a small and well-scoped model. Ideally, the retrieval and integration of biological knowledge for model annotation should be performed quickly, precisely, and with a minimum of manual effort. Here, we present a method using off-the-shelf semantic web technology which enables this process: the heterogeneous data sources are first syntactically converted into ontologies; these are then aligned to a small domain ontology by applying a rule base. Integrating resources in this way can accommodate multiple formats with different semantics; it provides...

We are developing software applications to perform meta-analysis of microarray experiments based on standardized experiment annotations aiming to identify similar experiments and cluster experiments. The applications were tested on files obtained from the ArrayExpress public repository. Annotation terms were used to compute experiment dissimilarities to find experiments related to a query experiment. These applications may motivate efforts of bench biologists to better annotate experiments.

Anpassung bestehender Methoden zur Abschätzung der Bodenerosion an die Bedingungen des Ökologischen Landbaus
Provedor de dados: 21
Autores: Siebrecht, Norman; Kainz, Maximilian; Hülsbergen, Kurt-Jürgen.
Dem ökologischen Landbau werden im Vergleich zu konventionellen Systemen häufig geringere Umweltbelastungen zugesprochen. Ein bedeutender Aspekt sind Wirkungen auf Böden und deren Eigenschaften: Untersuchungen belegen höhere Gehalte organischer Substanz, eine verbesserte Struktur und ein vielfältigeres Bodenleben. Auch Hinweise zu reduzierten Bodenabträgen bestehen. Analysen zum Ausmaß der Wirkungen und den Prozessen sind jedoch kaum verfügbar.  Bei der Modellierung von Bodenabträgen und der Ableitung von Maßnahmen sind entsprechende Informationen unabdingbar.  Auf Basis umfangreicher Recherche wurden im Projekt Ursachen-Wirkungs-Beziehungen zwischen ökologischer Bewirtschaftungsweise und Bodenerosion erarbeitet. Es zeigt sich, dass die Wirkungen nicht auf...

Anpassung der regionalisierten Versuchsauswertung mit überlappenden Anbaugebieten für Sortenversuche im ökologischen Landbau
Provedor de dados: 21
Autores: Gruber, Harriet; Zenk, Andrea.
Der in den meisten Bundesländern eingeschränkte Umfang an Sortenversuchen im ökologi-schen Landbau erschwert eine regionale Sortenempfehlung. Die vielfach geringere Ver-suchspräzision in diesen Anbausystemen verschärft das Problem, welches in häufig hohen Standardfehlern und großen Grenzdifferenzen seinen Ausdruck findet. Daher war es erforderlich auch für die Auswertung der Sortenversuche im ökologischen Landbau Anbaugebiete zu bilden und eine überregionale Auswertung unter Einbeziehung der Ergebnisse benachbarter Anbaugebiete vorzunehmen. Ein weiterer Schritt war die Einführung der Hohenheim-Gülzower Serienauswertung. Mit Hilfe der Regionalisierung und gegebenenfalls gewichteten Einbeziehung von Versuchsergebnissen angrenzender Gebiete (Überlappung) kann...

Answer to the challenges of the 21st century in the Hungarian pig sector
Provedor de dados: 31
Autores: Balogh,   Peter; Ertsey,   Imre; Szucs,   Istvan.
Whether particular countries, regions within countries, and particular societies gain or lose in the process of globalization depends on where they are in the process of agricultural transformation and to what extent they can adjust? The Hungarian pork chain faces considerable disadvantages in several aspects as opposed to competing countries. In countries with developed meat chain a powerful concentration could be observed, whereas in Hungary, although disintegration has not increased, decentralization still prevails. In our research the operation of the co-operative was modelled as a generalized network problem in 2008. The model allows the quantification of the number of pigs from given farms to slaughterhouses, the maximum revenue from sales, the...

Ant colony algorithm for analysis of gene interaction in high-dimensional association data
Provedor de dados: 96
Autores: Rekaya,Romdhane; Robbins,Kelly.
In recent years there has been much focus on the use of single nucleotide polymorphism (SNP) fine genome mapping to identify causative mutations for traits of interest; however, many studies focus only on the marginal effects of markers, ignoring potential gene interactions. Simulation studies have show that this approach may not be powerful enough to detect important loci when gene interactions are present. While several studies have examined potential gene interaction, they tend to focus on a small number of SNP markers. Given the prohibitive computation cost of modeling interactions in studies involving a large number SNP, methods need to be develop that can account for potential gene interactions in a computationally efficient manner. This study adopts...

Autores: Oliveira,Pollyana Yvonica de; Souza,Jorge Luiz Pereira de; Baccaro,Fabricio Beggiato; Franklin,Elizabeth.
In Amazonia, topographical variations in soil and forest structure within "terra-firme" ecosystems are important factors correlated with terrestrial invertebrates' distribution. The objective of this work was to assess the effects of soil clay content and slope on ant species distribution over a 25 km² grid covering the natural topographic continuum. Using three complementary sampling methods (sardine baits, pitfall traps and litter samples extracted in Winkler sacks), 300 subsamples of each method were taken in 30 plots distributed over a wet tropical forest in the Ducke Reserve (Manaus, AM, Brazil). An amount of 26,814 individuals from 11 subfamilies, 54 genera, 85 species and 152 morphospecies was recorded (Pheidole represented 37% of all...

The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere companion to the Arctic Climate Impact Assessment.

Antecedents Factors that Influence Soy Consumption: A Structural Equation Modeling Approach

Autores: Balasubramanian,   Siva K.; Moon,   Wanki; Rimal,   Arbindra; Coker,   Kesha.
We propose a structural model of antecedent factors that affect the frequency of soy consumption. This model, suggests that soy-general knowledge influences perceptions about nutrition concern, health benefits of soy, soy related personal beliefs and personal attitudes toward soy. Health benefits of soy, in turn, impacts soy-related personal beliefs and personal attitudes toward soy. Additionally, soy-related personal beliefs influence personal attitudes toward soy. Finally, both nutrition concern and personal attitudes toward soy drive the frequency of soy consumption. Elaborate tests with calibration and validation samples (derived from a large and nationally representative survey) provide robust empirical support for the proposed model. Implications for...

Autores: Terasawa,José Maurício; Panobianco,Maristela; Possamai,Edilberto; Koehler,Henrique Soares.
O retardamento da colheita a partir da maturidade fisiológica pode influenciar negativamente a qualidade da semente devido a sua exposição a condições menos favoráveis do ambiente. Normalmente, o produtor aguarda a redução de umidade das sementes e inicia a colheita tão logo seja possível efetuá-la. A pesquisa teve por objetivo avaliar a influência da colheita da soja, com diferentes teores de água, sobre a qualidade fisiológica das sementes produzidas, procurando-se determinar o melhor momento de colheita antecipada para a cultura. Para tanto foram realizados experimentos na safra 2006/2007 com duas cultivares: FTS Campo Mourão RR e FTS Cascavel RR, de ciclo precoce e semiprecoce, respectivamente, sendo as sementes de cada cultivar colhidas no estádio R8,...

Anterior caudal transverse processes in sauropod dinosaurs: morphological, phylogenetic and functional aspects
Provedor de dados: 41
Autores: Gallina,Pablo Ariel; Otero,Alejandro.
A great amount of the sauropod record is based on caudal vertebrae. Morphological analyses of tail bones until recently were essentially focused on centrum shape, with other anatomical features being poorly studied. A detailed description of anterior caudal transverse processes (ACTP) is presented here in order to improve the scarce knowledge of this tail part. Within Sauropoda there are four different ACTP morphological types; one simple (single element projected on the vertebral side) and three complex (lateral bony laminar plates supported by bony bars). The identity of the ACTP elements includes a rib, a synapophysis and laminar components, which are renamed here. The ventral laminae include the anterior centroparapophyseal lamina (acpl) and the...

Antes de criar abelhas, confira a flora de sua região.
Provedor de dados: 14
Autores: LOPES, M. T. do R.
O Piauí tem apresentado um crescimento expressivo no setor apícola devido ao seu elevado potencial para a atividade, traduzindo-se em altos níveis de produção e exportação de mel. Além do crescimento da apicultura, nos últimos anos também tem sido verificado um interesse crescente de produtores em trabalhar com meliponicultura, a criação de abelhas nativas sem ferrão. Essa atividade tem atraído pessoas que já trabalham com abelhas ou mesmo que nunca trabalharam, mas que se sentem atraídas pelo manejo relativamente fácil dessas espécies e pelo alto valor agregado de seus produtos. Entretanto, um dos primeiros conselhos às pessoas que querem investir na criação de abelhas, é a observação da flora no local onde serão instalados os apiários ou meliponários.

Anthropogenic carbon distributions in the Atlantic Ocean: data-based estimates from the Arctic to the Antarctic
Provedor de dados: 5
Autores: Vazquez-rodriguez, Marcos; Touratier, Franck; Lo Monaco, Claire; Waugh, D. W.; Padin, X. A.; Bellerby, R. G. J.; Goyet, Catherine; Metzl, Nicolas; Rios, Aida F.; Perez, Fiz F.
Five of the most recent observational methods to estimate anthropogenic CO2 (C-ant) are applied to a high-quality dataset from five representative sections of the Atlantic Ocean extending from the Arctic to the Antarctic. Between latitudes 60 degrees N-40 degrees S all methods give similar spatial distributions and magnitude of C-ant. However, discrepancies are found in some regions, in particular in the Southern Ocean and Nordic Seas. The differences in the Southern Ocean have a significant impact on the anthropogenic carbon inventories. The calculated total inventories of C-ant for the Atlantic referred to 1994 vary from 48 to 67 Pg (10(15) g) of carbon, with an average of 54 +/- 8 Pg C, which is higher than previous estimates. These results, both the...

Anthropogenic disturbance on nursery function of estuarine areas for marine species
Provedor de dados: 5
Autores: Courrat, A.; Lobry, Jeremy; Nicolas, D.; Laffargue, Pascal; Amara, R.; Lepage, M.; Girardin, M.; Le Pape, O.
Estuaries serve as nursery grounds for many marine fish species. However increasing human activities within estuaries and surrounding areas lead to significant habitat loss for the juveniles and decrease the quality of the remaining habitats. This study is based on the data of 470 beam trawls from surveys that were conducted in 13 French estuaries for the purpose of the European Water Framework Directive. It aimed at testing the effects of anthropogenic disturbances on the nursery function of estuaries. With a multispecific approach based on ecological guilds, two fish metrics, abundance and species richness of Marine juvenile migrant fishes, were used as proxies for the estuarine nursery function. Indices of heavy metal and organic contaminations were...

Cryptosporidium parvum is a zoonotic apicomplexa-protozoan pathogen that causes gastroenteritis and diarrhoea in mammals worldwide. The organism is transmitted by ingestion of oocysts, which are shed in faeces, and completes its lifecycle in a single host.^1^ C. parvum is ubiquitous on dairy operations worldwide and is one of the leading causes of diarrhoea in calves on these farms.^2,3^ Here, for the first time, we describe the antibody response in a large group of cows to a recombinant C. parvum oocyst surface protein (rCP15/60) vaccine and the antibody response in calves fed rCP15/60-immune colostrum produced by these vaccinated cows. Results of recent genotype surveys indicate that calves are the only major reservoir for C. parvum infections in...

Autores: Kaushik,Darpan; Tripathi,Ashish; Tripathi,Rashmi; Ganachari,Madiwalayya; Khan,Suroor Ahmad.
Bacopa monnieri (L), belonging to the Scrophulariaceae family and commonly known as Brahmi, is well known in India for its CNS activity but its neuropharmacological effect has not yet been explored. In the present study, the antiepileptic effects of the plant were investigated. The ethanolic extract of Bacopa monniera was tested for anticonvulsant activity in albino rats, using different convulsive models. The ethanolic extract of leaves produced significant anticonvulsant activity for all the different models studied. The present study shows a probable mechanism of action similar to that of benzodiazepines (GABA agonist). Thus, these results emphasize the need to diversify by using alternative therapeutic approaches pertaining to herbal medicine, where a...

Provedor de dados: 56
Autores: de Faria,D.R.G.; Santana,J.S.; Menani,J.V.; de Paula,P.M.
Besides other physiological functions, adenosine-5'-triphosphate (ATP) is also a neurotransmitter that acts on purinergic receptors. In spite of the presence of purinergic receptors in forebrain areas involved with fluid-electrolyte balance, the effect of ATP on water intake has not been investigated. Therefore, we studied the effects of intracerebroventricular (icv) injections of ATP (100, 200 and 300 nmol/µL) alone or combined with DPCPX or PPADS (P1 and P2 purinergic antagonists, respectively, 25 nmol/µL) on water intake induced by water deprivation. In addition, the effect of icv ATP was also tested on water intake induced by intragastric load of 12% NaCl (2 mL/rat), acute treatment with the diuretic/natriuretic furosemide (20 mg/kg), icv angiotensin...

Antifungal and antitumor models of bioactive protective peptides
Provedor de dados: 42
Autores: Rodrigues,Elaine G.; Dobroff,Andrey S.; Taborda,Carlos P.; Travassos,Luiz R.
Peptides are remarkably reactive molecules produced by a great variety of species and able to display a number of functions in uni-and multicellular organisms as mediators, agonists and regulating substances. Some of them exert cytotoxic effects on cells other than those that produced them, and may have a role in controlling subpopulations and protecting certain species or cell types. Presently, we focus on antifungal and antitumor peptides and discuss a few models in which specific sequences and structures exerted direct inhibitory effects or stimulated a protective immune response. The killer peptide, deduced from an antiidiotypic antibody, with several antimicrobial activities and other Ig-derived peptides with cytotoxic activities including antitumor...

Clostridium perfringens is a normal inhabitant of the intestinal tract of chickens as well as a potential pathogen that causes necrotic enteritis and colangio hepatitis. The minimum inhibitory concentration (MIC) of seven different compounds used for therapy, growth promotion or prevention of coccidiosis was determined by agar dilution method for 55 C. perfringens strains isolated from the intestines of broiler chickens. All strains showed high susceptibility to penicillin, avilamycin, monensin and narasin. Only 7.3% of the strains showed an intermediated sensitivity to lincomycin, and 49 (89.1%) were considered susceptible. For tetracycline and bacitracin, 41.8% and 47.3% of strains, respectively, were considered resistant.

Anting behaviour with millipedes by the dendrocolaptid bird Xiphocolaptes albicollis in southeastern Brazil
Provedor de dados: 49
Autores: Sazima,Ivan.
Several bird species practice anting. While anting a bird holds an ant or other arthropod that produces toxic or irritating secretions and rubs it on the plumage. Here I describe the White-collared Woodcreeper (Xiphocolaptes albicollis) rubbing its body with millipedes of the orders Spirostreptida and Polydesmida while foraging among banana stumps or at bromeliad clumps in southeastern Brazil. On three occasions I recorded the bird holding a millipede in the bill and rubbing it against its chest, belly, and wings. From time to time the millipede was "chewed", and hammered against the substratum and then rubbed on the plumage again. After a while the millipede was ingested or dropped. Bromeliads harbour a rich fauna that includes mosquitoes, ticks, spiders,...

Antinociception synergy between the peripheral and spinal sites of the heme oxygenase-carbon monoxide pathway
Provedor de dados: 56
Autores: Nascimento,C.G.O.; Branco,L.G.S.
We have shown that the peripheral and spinal cord heme oxygenase (HO)-carbon monoxide (CO)-soluble guanylate cyclase-cGMP pathways play an important role in antinociception in the rat experimental formalin model. Our objective was to determine if there is synergism between peripheral (paw) and spinal HO-CO pathways in nociception. Rats were handled and adapted to the experimental environment for a few days before the formalin test, in which 50 µL of a 1% formalin was injected subcutaneously into the dorsal surface of the right hind paw. The animals were then observed for 1 h and the frequency of flinching behavior was taken to represent the nociceptive response. Thirty minutes before the test, rats were pretreated with intrathecal injections of the HO...

Mentha x villosa Huds (Labiatae) is an aromatic herb widely used in folk medicine. Since the essential oil of the herb has many pharmacological activities, including antispasmodic effects, we determined whether the oil and its major constituent, piperitenone oxide (PO), have antinociceptive activity. The essential oil of M. x villosa (EOMV) and PO administered orally at 200 mg/kg (vehicle: 0.1% Tween 80 in water) significantly reduced the writhings induced by acetic acid from control values of 59.5 ± 3.1 s (N = 10) to 31.9 ± 2.8 s (N = 10) and 23.8 ± 3.4 s (N = 10), respectively. When administered at 100 and 200 mg/kg, EOMV reduced the paw licking time for the second phase of the formalin test from the control value of 20.6 ± 2.1 s (N = 13) to 5.3 ± 2.2 s...

The aim of this work is to review the most important topics about the antiophidic sera sterility, including obtaining methods, sterilization procedures and clean room control using Vital Brazil Institute (VBI) as an example. Bibliographical research was performed through Medline, Lilacs, PubMed, ISI and the Fundação Oswaldo Cruz - RJ and VBI Libraries, from 1960 to 2009. The antiophidic sera for human use are immunobiologic products produced in Brazil by three national laboratories, including VBI. Due to the parenteral use, these products should be sterile and pyrogen-free, which demands the microbiological control during the whole fabrication process. The sterility and pyrogen tests are important steps to ensure the quality and safety of these...

Antioxidant activity and physical-chemical properties of spray and spouted bed dried extracts of Bauhinia forficata
Provedor de dados: 60
Autores: Souza,Claudia Regina Fernandes; Georgetti,Sandra Regina; Salvador,Marcos José; Fonseca,Maria José Vieira; Oliveira,Wanderley Pereira.
Two distinct drying methods (spouted bed and spray drying) were used for production of dried extracts of Bauhinia forficata Link (Leguminosae, Caesalpinoideae). High-quality powder products in terms of physical and chemical properties were obtained. HPLC fingerprints revealed that the chromatographic profiles of flavonoid compounds present in the dried extract did not change significantly, due to drying. In general, the spouted bed drying caused a degradation of total flavonoids than was lower than that of the spray drying. Antioxidant properties of the dried extract, examined by their radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) and inhibition of lipid peroxidation induced by Fe+2 assays (LPO), confirmed their...

Abstract &lt;img border=0 id="_x0000_i1034" src="../img/back.gif"&gt; The present study describes the in vitro antimicrobial and antioxidant activity of methanol and water extracts of sweet and bitter apricot (Prunus armeniaca L.) kernels. The antioxidant properties of apricot kernels were evaluated by determining radical scavenging power, lipid peroxidation inhibition activity and total phenol content measured with a DPPH test, the thiocyanate method and the Folin method, respectively. In contrast to extracts of the bitter kernels, both the water and methanol extracts of sweet kernels have antioxidant potential. The highest percent inhibition of lipid peroxidation (69%) and total phenolic content (7.9 ± 0.2 µg/mL) were detected in the methanol extract of...

Food industry generates a significant amount of seed wastes from the juice production, frozen pulps and jams. Considering that the characterization of wastes is the first step to determine their potential use, the aim of the present study was to determine the composition and the antioxidant capacity of seeds from pitanga fruits with different flesh colors (purple, red and orange). Chemical composition results revealed that pitanga seeds are a good source of insoluble dietary fiber, with low protein and fat levels, and no relevant differences were found among pitanga seeds from different flesh colors. Pitanga seed extracts had powerful antioxidant capacity that was partially correlated to their high phenolic content and showed some variation according to...

Schisandra propinqua (Wall.) Baill.(Schisandraceae) is widely used as a Chinese folk medicine. In this study, activity-guided fractionation of the ethanol extract from the stem of Schisandra propinqua led to the isolation of four extracts. Subsequently, a neolignan 4,4-di(4-hydroxy-3-methoxyphenly)-2,3-dimethylbutanol was isolated from the EtOAc part of the stem of Schisandra propinqua, the free radical scavenging activities of which were researched in vitro. The present work demonstrated that extracts and pure compound possessed scavenging activities to DPPH, superoxide anions and hydroxy radical, and could depress lipid peroxidation reaction induced by oxygen radical produced by the Fe2+/cysteine system in vitro. This suggests that the traditional...

Antioxidants and dairy production: the example of flax
Provedor de dados: 96
Autores: Petit,Hélène V.
This manuscript reports on the main problems decreasing productivity of dairy cows (e.g. fatty liver syndrome and poor fertility) and how antioxidants could enhance it. High producing dairy cows are prone to oxidative stress, and the situation can be exacerbated under certain environmental, physiological, and dietary conditions. Antioxidants have important effects on the expression of genes involved in the antioxidant status, which may enhance animal health and reproduction. Moreover, antioxidants may contribute to decrease the incidence of spontaneous oxidized flavour in milk enriched in polyunsaturated fatty acids. Plant lignans are strong antioxidants and flax is the richest source of plant lignans. Flax lignans are converted in the mammalian lignans...

Two leaf-miner species occur in European vineyards, i.e. Holocacista rivillei (Stainton) (Lepidoptera Heliozelidae) and Phyllocnistis vitegenella Clemens (Lepidoptera Phyllocnistidae).  In the summer of 2007, leaf mines similar to those caused by H. rivillei were observed in a vineyard located in north-eastern Italy. However, the first portion of mines (linear tortuous) was lacking and thus the occurrence of a different species was suspected. Larvae were reared in controlled conditions to obtain adults and the latter differed from those of H. rivillei because of their size and wing patterns. Adults belonged to the genus Antispila Hübner, but not to the species of this genus currently known for Italy and Europe. Antispila sp. was detected for the first time...

Thalassophryne nattereri (niquim) is a venomous fish responsible for numerous accidents involving fishermen in northern and northeastern Brazil. The aim of the present investigation was to evaluate the action of antivenom on renal effects caused by Thalassophryne nattereri venom. Isolated kidneys of Wistar rats were perfused with a previously dialyzed Krebs-Henseleit solution containing 6 g% bovine serum albumin. The antivenom action was studied through perfusion pressure (PP), renal vascular resistance (RVR), urinary flow (UF) and glomerular filtration rate (GFR). The niquim venom (1 µg/mL), the antivenom alone (1 µg/mL) or the venom incubated with antivenom were added to the system 30 minutes after the beginning of each perfusion. Previous works have...

Ant-plant associations in different forests in Venezuela
Provedor de dados: 82
Autores: Goitía,William; Jaffé,Klaus.
We evaluated the hypothesis that the abundance and species distribution of two different kinds of myrmecophilous plants is influenced differently by the ant diversity and abundance. In eight different natural forests in Venezuela we estimated the species richness and abundance of plants, ants on the soil and on the canopy, the leaf damage of plants and soil nutrients. The main results of the study show that plants with domatia (PD) and plants with extrafloral nectaries (PEFN) have different relationships with ants and suffer from different ecological constraints. PD attract a more specific group of ants than PEFN. Our results are consistent with the hypothesis that domatia are adaptations that help plants to increase rare nutrient uptake rather than for...

Autores: Silva,Fernando Rodrigues da; Santos,Rodrigo Souza; Nunes,Maria Andréia; Rossa-Feres,Denise de Cerqueira.
Although it is generally assumed that agriculture negatively influences amphibian populations, few studies on the effects of agricultural cultivations on neotropical anuran have been conducted. As a contribution to the knowledge about anuran in agriculture, the present study sought to identify the anuran species present in three different agrossystems. We used data from anurans captured in pitfall traps initially proposed for a survey of harvestmen fauna in three agrossystems (corn, soybean, and rubber tree). Four anuran species found in the pitfall traps belong to two Families: Leptodactylidae: Leptodactulus fuscus and L. mystacinus; and Leiuperidae: Eupemphix nattereri and Physalaemus cuvieri. In corn plantation, four species and 30 individuals were...

Higher prevalence rates of anxiety and depression have been reported in parents of children with attention-deficit/hyperactivity disorder (ADHD). The interaction between the burden of ADHD in offspring, a higher prevalence rate of this highly inherited disorder in parents, and comorbidities may explain this finding. Our objective was to investigate levels of ADHD, anxious and depressive symptomatology, and their relationship in parents of ADHD children from a non-clinical sample using a dimensional approach. The sample included 396 students enrolled in all eight grades of a public school who were screened for ADHD using the SNAP IV rating scale. Positive cases were confirmed through a semi-structured interview. Parents of all 26 ADHD students and 31 paired...

This article describes the occurrence of aortic body tumors in four dogs from Southern Brazil. All dogs were males, more than 9 year of age; most of these were from the Boxer breed of dogs. The animals had large neoplastic growths at the base of the heart, which demonstrated histologic characteristics consistent with that of aortic body tumor. By immunohistochemistry, tissue sections from all dogs reacted positively to neuron specific enolase. These cases might represent the first description of this tumor in dogs from Brazil, as confirmed by immunohistochemistry.

Autores: PEREIRA, F. de M.
Matéria prima para a produção apícola, a cera de abelha foi muito utilizada e valorizada no passado, porém passou por um período de desvalorização, sendo substituída por ceras sintéticas, que possuem um custo menor. Contudo, recentemente a cera de abelha voltou a ter destaque no mercado mundial devido a suas características peculiares de aroma e plasticidade, seus efeitos medicinais e a tendência mundial em se consumir produtos naturais. Atualmente existe uma escassez total ou sazonal desse produto nos países industrializados.

This aim of this article is to analyze the relation of size and operational efficiency of sugar and ethanol plants in the northeastern region of São Paulo state. In order to achieve this goal, a survey was conducted to identify the consumption of the main resources (inputs) and product creation (outputs) in a random sample of twenty six units, which allowed for their classification according to size. This enabled the creation of an efficiency ranking, using Data Envelopment Analysis (DEA), whose variables were chosen by the stepwise method. The results suggest that, for the plants studied, there is no direct relation between size and operational efficiency, which can be explained by technical aspects associated to the inputs. The results provide subsides...

O teste de raios X vem sendo empregado em programas de qualidade e como auxiliar nos estudos morfológicos e fisiológicos de sementes de diversas espécies. A arnica (Lychnophora pinaster Mart.) é uma espécie medicinal que apresenta um número elevado de aquênios cheios ou mal formados por ocasião da frutificação, o que dificulta a produção de sementes necessária para o suprimento de uma demanda cada vez maior, pela indústria farmacêutica. Para verificar o efeito do estádio de maturação de aquênios de arnica na qualidade fisiológica das sementes e a eficiência do teste de raios X na separação de sementes mal formadas, foram coletados, no mês de dezembro de 2003, aquênios provenientes de uma população de plantas do município de Itumirim, MG.

To determine whether fibroblasts from Blanco Orejinegro cattle, exhibit any level of resistance to infection against vesicular stomatitis virus (VSV) serotypes Indiana (VSV-I) or New Jersey (VSVNJ), 30 fibroblast cultures were phenotyped to evaluate their resistance/susceptibility. Thirty three % of Blanco Orejinegro fibroblast cultures were classified as very resistant, 50% as resistant, and 17% as susceptible to VSV-I infection, whereas 20% were classified as very resistant, 50% as resistant and 30% as susceptible to VSV-NJ infection. Therefore, there appears to be a large variation in phenotypic polymorphism among the fibroblasts to infection by VSV. To elucidate the mechanisms responsible for this diversity, we searched for a possible relationship...

The question of how the human brain combines disparate sensory inputs to construct a unified body image is of longstanding interest^1,2,3^ . We approached this subject by studying the unusual medical condition of apotemnophilia, in which otherwise mentally normal individuals express the strong and persistent desire for the amputation of a specific healthy limb^4,5,6^ . Here we show using functional brain imaging - magnetoencephalography (MEG) - that the condition is characterised by an absence of activity in the right superior parietal lobule (SPL) when the affected limb is touched. When this discovery is combined with our earlier finding of a simultaneous increase in skin conductance response (SCR) on touching the affected limb^7^ , which reflects...

This is a case study that aimed at proposing a management method based on macroprocesses to determine and achieve strategic goals for a beef cattle enterprise in order to maintain or to increase the company's competitiveness. The method suggests using a series of tools mentioned in the literature that were organized providing logical reasons for the managers to build the management system. When mapping the processes of the studied enterprise, four macroprocesses were identified, which were sustained by 21 support processes, in addition to three management processes. The strategic aims were determined by the internal and external environmental analysis, resulting in five priority items, and the processes considered critical to achieve them were described by...

Application of a periodic table for the genetic code of the influenza A/H3N2 virus
Provedor de dados: 17
Autores: Susumu Morimoto.
The progress of life sciences would be greatly enhanced if biological data were available in a manner similar to the periodic table of the elements. Currently, the mutation rules for influenza viruses remain ambiguous. In light of the threat of Avian Influenza there is an urgent need to understand the governing principles behind influenza virus mutations. Here, the applicability of a periodic table for the genetic code of influenza A/H3N2 virus is explored. In addition, two rules regarding single point mutations of the hemagglutinin gene are presented. The first rule states that non-synonymous single point mutations are intimately associated with the first or second base replacements between two congener codons of four groups (5, 6, 9, and 10) in the...

Autores: Otieno,   David Jakinda; Omiti,   John M.; Nyanamba,   Timothy O.; McCullough,   Ellen B.
Involvement of farmers especially those at the smallholder level, in commercial agriculture is an important pathway towards economic development.  There is a growing literature on the extent and determinants of market participation by farmers in different areas of the world. However, many studies fail to statistically account for the choice of either pooled models or disaggregated analysis of data from multiple sites. The consequence is that the scope and relevance of policy inferences on the basis of those results are limited. This study contributes to knowledge in filling the analytical void through application of the Chow test. Primary data from seventy seven vegetable farmers is analysed to understand factors that influence the level of market...

Application of Internal Control Systems in Organic Export  Companies: Two Case Studies from Uganda
Provedor de dados: 21
Autores: Reckling, Moritz; Preißel, Sara.
The organic agricultural sector of Uganda is considered the most developed in Africa with a total of 296,203 ha organic certified land and the most certified organic producers worldwide (206,800), 90% of whom are small scale farmers. They are certified organic under contract production by export and processing companies, using an Internal Control System (ICS) as a group certification scheme defined by IFOAM (2004). The ICS is a viable and well accepted tool to certify small scale producers in developing countries all over the world. In Uganda however, certification difficulties are stated among the main constraints for the organic sector development.  Therefore, a qualitative study was conducted from June to August 2008 that aimed at better understanding...

Application of Modified Internal Rate of Return Method for Watershed Evaluation
Provedor de dados: 31
Autores: Satyasai,   K.J.S.
The use of modified IRR in developmental projects has been demonstrated by using data pertaining to four watersheds — two from Tamil Nadu and two from Maharashtra. The conventional internal rate of return (IRR) widely used in project evaluation, suffers from certain problems, most important one being the assumption of reinvestment at the rate of IRR, which has been often contested in project evaluation literature. The ranking of projects based on IRR and NPV may also come into conflict due to this assumption. Scale and time span differences across projects often make it difficult to compare. In India, the use of conventional IRR still prevails even though improvements have been suggested in literature long ago, perhaps for the reasons of ease in handling....

Polycyclic aromatic hydrocarbons (PAHs) constitute a group of priority pollutants which are present at high concentrations in the soils of many industrial contaminated sites. Pollution by these compounds may stimulate growth of organisms able to live in these environments causing changes in the structure of the microbial community due to some cooperative process of metabolization of toxic compounds. A long-term PAH-contaminated soil was stored for several years and used to analyze the native microbiota regarding their ability to grow on pyrene, benzo[a]pyrene, as well as in mixtures of LMW- and HMW-PAHs. Molecular profiles of the microbial community was assessed by PCR-DGGE of 16S rRNA gene, and the number of bands observed in DGGE analyses was interpreted...

Application of POCIS for the monitoring of pesticides, pharmaceuticals and alkylphenols in marine water
Provedor de dados: 5
Autores: Tapie, Nathalie; Munaron, Dominique; Gonzalez, Jean-louis; Budzinski, Helene.
With the new European legislation (the Water Framework Directive, 2000/60/EC), the decision makers responsible for the assessment of the environmental contamination require simple monitoring tools. Passive sampling methods seem to be promising tools for the sampling of polar organic compounds in water, especially in marine waters where important dilutions and low concentrations are usual. They are taking into account the temporal variability and integrating the contamination over period of time. This work presents a study, on a large scale, of the contamination of French Mediterranean coastal waters realized in partnership with the Water Agency Rhône Méditerranée Corse (AERMC), and Coastal Water Quality Offices (CQEL).

Autores: Yakubu,A; Ayoade,J. A.
Body weight and four morphostructural traits namely body length, heart girth, thigh circumference and ear length of 103 New Zealand White x Chinchilla crossbred rabbits were measured. The investigation aimed at describing objectively the interdependence among conformation traits and to predict body weight from their independent factor scores using principal component analysis. Phenotypic correlations between body weight and body dimensions were highly significant (r=0.61 ­ 0.91; P&lt;0.01). Pairwise correlations of the body shape characters ranged from moderate to high values. From the factor analysis with varimax rotation of the intercorrelated traits, two principal components which accounted for 90.27% of the total variance were extracted. The first...

A logical starting point for climate change adaptation in the forest sector is to proactively identify management practices and policies that have a higher likelihood of achieving management objectives across a wide range of potential climate futures. This should be followed by implementation of these options and monitoring their success in achieving management objectives within an adaptive management context. Here, we implement an approach to identify locally appropriate adaptation options by tapping into the experiential knowledge base of local forest practitioners while at the same time, building capacity within this community to implement the results. We engaged 30 forest practitioners who are involved with the implementation of a regional forest...

Application of the comet assay in erythrocytes of Oreochromis niloticus (Pisces): a methodological comparison
Provedor de dados: 74
Autores: Christofoletti,Cintya A.; David,José Augusto O.; Fontanetti,Carmem S.
The present study applied the comet assay to erythrocytes of Oreochromis niloticus with the aim of improving protocols to detect DNA damage in these cells, by using two distinct pHs (pH = 12.1 and pH &gt; 13) and evaluating whether there is a correspondence between silver and ethidium bromide staining. Comets were visually examined and, the frequency of cells with and without damage was obtained, as well as the distribution of classes and scores. By using the Kruskal-Wallis test, our results revealed that pH 12.1 is more effective, although both pHs can be used. Our findings also suggest that silver staining can substitute ethidium bromide, an expensive and highly toxic stain that requires specific equipment for examination.

Provedor de dados: 101
Autores: de la Vega,R; Díaz,G; Camejo,A; García,I.
In this paper, a tick sampling method developed by authors was employed with the purpose of saving acaricides and decreasing environmental pollution by the use of acaricidal dip control bathing bovines in relation to a critical number of estimated ticks. Twenty-six Jersey cows in production were sampled. The selected sampling regions were: rear leg, udder, perinea and tail. Samplings were done from 7 to 8 am, and female tick standard size pattern was 6 mm or longer. Every two weeks approximately, samplings and acaricidal baths were done (13 samplings in total). Only cows with 10 or more ticks received acaricidal baths. Results showed that the procedure allows saving 50% of acaricides.

Applying precision feeding techniques in growing-finishing pig operations
Provedor de dados: 96
Autores: Pomar,Cândido; Hauschild,Luciano; Zhang,Guo-Hua; Pomar,Jesus; Lovatto,Paolo Alberto.
The high cost of feed ingredients, the use of non-renewable sources of phosphate and the dramatic increase in the environmental load resulting from the excessive land application of manure are major challenges for the livestock industry. Precision feeding is proposed as an essential approach to improve the utilization of dietary nitrogen, phosphorus and other nutrients and thus reduce feeding costs and nutrient excretion. Precision feeding requires accurate knowledge of the nutritional value of feedstuffs and animal nutrient requirements, the formulation of diets in accordance with environmental constraints, and the gradual adjustment of the dietary nutrient supply to match the requirements of the animals. After the nutritional potential of feed...

Autores: Fleck, M.
Since 1998 RODELIKA is officially registered as a newly bred carrot variety. It had been developed by positive mass-selection over a 13 year period, based on an old-established variety within a farm based biodynamic system. The goal was a fine root with good health and a focus on taste and ability of maturation. Thus a selection-scheme in organoleptic characteristics sweetness and aroma was created. Numerous investigations demonstrate the very high inner quality of RODELIKA. Property rights of this open-pollinated variety are held by the charitable association Kultursaat eV as a common heritage.

Approaches and frameworks for management and research in small-scale fisheries in the developing world
Provedor de dados: 31
Autores: Andrew,   Neil; Evans,   Louisa.
Commonly adopted approaches to managing small-scale fisheries (SSFs) in developing countries do not ensure sustainability. Progress is impeded by a gap between innovative SSF research and slower-moving SSF management. The paper aims to bridge the gap by showing that the three primary bases of SSF management--ecosystem, stakeholders’ rights and resilience--are mutually consistent and complementary. It nominates the ecosystem approach as an appropriate starting point because it is established in national and international law and policy. Within this approach, the emerging resilience perspective and associated concepts of adaptive management and institutional learning can move management beyond traditional control and resource-use optimization, which largely...

Approximating optimal numerical solutions to bio-economic systems: How useful is simulation-optimization?
Provedor de dados: 31
Autores: Börner,   Jan; Higgins,   Steven Ian; Scheiter,   Simon; Kantelhardt,   Jochen.
For applications in agricultural economics, complex ecological systems are often oversimplified to the extent that ecologists rarely consider model results valid. Recursive optimization of complex systems represents an alternative, but requires strong assumptions regarding time preference and uncertainty. In this paper we explore the implications of merely approximating “true” optima of complex dynamic optimization problems using a technique called simulation-optimization. We develop a standard discrete renewable resource use problem and solve it numerically using both simulation-optimization and non-linear mathematical programming. We subsequently introduce non-linearity and uncertainty and graphically compare the performance of simulation-optimization...

Aprovechamiento tradicional de cactáceas y agaváceas en los municipios de Tepeyahualco de Cuauhtémoc y Huitziltepec, Puebla
Provedor de dados: 32
Autores: Martínez Vásquez, Esteban.
Las cactáceas y agaváceas son dos familias botánicas de gran importancia por el número de especies que presentan, y por los múltiples usos que han tenido entre la población de México. En los municipios de  Tepeyahualco de Cuauhtémoc y Huitziltepec, diversas especies de cactáceas y agaváceas se han utilizado desde tiempos inmemoriales, con lo que se han generado importantes conocimientos sobre su manejo, producción y reproducción, aunque en la actualidad existen factores que están interfiriendo en el proceso de transmisión de éstos, lo cual amenaza la reproducción de los agroecosistemas y vulnera la diversidad de distintas especies de estas plantas. Este trabajo tuvo como objetivos registrar y sistematizar el conocimiento tradicional que aún mantienen los...

Aproveitamento da manipueira ou tucupi como adubo e outros usos na agricultura familiar no Maranhão.
Provedor de dados: 14
Autores: SOUZA, L. da S.; SANTOS, V. da S.; DINIZ, M. de S.
O cultivo de mandioca no Maranhão ocorre em terras bastantes frágeis, a maioria delas arenosas ou médias, com baixa capacidade para fornecer nutrientes exigidos em maiores quantidades pela mandioca ( fósforo, cálcio, magnésio e potássio). Além disso, a prática da derrubada e queima da vegetação nativa, e não utilização de adubos na mandioca contribuem para enfraquecer ainda mais a terra, fazendo com que, geralmente, seja feito apenas um cultivo de mandioca em cada área, e depois ela é deixada em pousio (descansando).

Aproveitamento do Óleo das Amêndoas de Tucumã do Amazonas na Produção de Biodiesel
Provedor de dados: 36
Autores: Barbosa,Banny Silva; Koolen,Hector Henrique Ferreira; Barreto,Andreza Cruz; Silva,João Domingos da; Figliuolo,Roberto; Nunomura,Sergio Massayoshi.
A falta de disponibilidade de energia elétrica é um dos principais motivos pelo baixo Índice de Desenvolvimento Humano das comunidades isoladas localizadas na Amazônia. O biodiesel produzido a partir de óleos vegetais extraídos de espécies oleaginosas nativas de forma sustentada é uma das melhores alternativas energéticas para a região. O tucumã do amazonas, Astrocaryum aculeatum, é uma espécie de palmeira que produz um fruto muito apreciado na região, a partir do qual se obtém uma amêndoa com alto teor de óleo. Nesse estudo, foi avaliada a produção de biodiesel etílico, a partir de diferentes lotes de óleos de tucumã do amazonas, com índices de acidez baixos e elevados, pela transesterificação por catálise básica e ácida homogêneas, respectivamente.

Autores: LIMA, W. A. A. de.
Embrapa Amazônia Ocidental tem atuado em diferentes linhas de pesquisa com a cultura do dendê, desde a produção de sementes até a produção de biodiesel. Tem uma usina-piloto no Campo Experimental do Rio Urubu (município de Rio Preto da Eva), distante 154 quilômetros de Manaus, onde existe a produção de biodiesel pelo método de transesterificação etílica. Em outras palavras, misturamos o óleo de dendê com etanol e soda, tendo como resultado biodiesel e glicerina. O aproveitamento econômico dessa cultura andou esquecido, mas ganhou força com o Plano Nacional de Produção e Uso de Biodiesel. Esse combustível renovável é um fato concreto e hoje os postos de gasolina abastecem com até 3% de biodiesel. É algo compulsório, que já está na matriz energética...

Autores: Giacomini,Sandro José; Aita,Celso; Jantalia,Claudia Pozzi; Urquiaga,Segundo.
O objetivo deste trabalho foi avaliar o aproveitamento do N amoniacal de dejetos líquidos de suínos (DLS) pela cultura do milho (Zea mays). O experimento foi conduzido em Argissolo Vermelho distrófico arênico. Os tratamentos avaliados consistiram da aplicação ou não de DLS sobre resíduos culturais de aveia, em plantio direto e preparo reduzido do solo. Para quantificar o destino do N amoniacal aplicado, a fração amoniacal dos DLS foi enriquecida com (15NH4)2SO4 . O aproveitamento do N amoniacal dos DLS pelo milho foi de apenas 15,3% e não diferiu com o uso do DLS em plantio direto ou em preparo reduzido do solo. Na maturação fisiológica do milho, a quantidade de 15N dos DLS recuperada no solo, até a profundidade de 120 cm, e na planta (parte...

Aproveitamento pelo trigo do nitrogênio residual da crotalária (Crotalaria juncea) e da uréia aplicado ao solo em cultivo precedente
Provedor de dados: 65
Autores: Lange,Anderson; Bologna,Isabela Rodrigues; Faroni,Carlos Eduardo; Trivelin,Paulo Cesar Ocheuze.
O cultivo de adubos verdes no sistema produtivo tem por objetivo o fornecimento de nitrogênio ao solo. Porém, muitas vezes os benefícios não são a curto prazo. Nesse sentido, acompanhar a taxa de fornecimento de nitrogênio proveniente dos resíduos ao longo dos anos se faz necessário. O objetivo do trabalho foi avaliar o aproveitamento do nitrogênio residual no solo do adubo verde (Crotalaria juncea L.)-15N e da uréia-15N, em fertilização conjugada e separada, no segundo ano de cultivo pelo trigo (Triticum aestivum L.). O experimento foi desenvolvido em vasos com 4kg de solo (Latossolo Vermelho distrófico típico), em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições. As quantidades de 15N residual do primeiro cultivo eram:...

Aqueous synthesis of CdTe quantum dot as biological fluorescent probe for monitoring methyl parathion by fluoro-immunosensor
Provedor de dados: 17
Autores: Raghuraj Chouhan; Aaydha Vinayaka; Munna Thakur.
Bioconjugation of quantum dots (QDs) provide high resolution in biological fluorescent labelling as a result of physical and optical properties of QDs. This intrinsic property of QDs can be made use of for sensitive detection of target analytes including food and environmental monitoring. In this investigation, we report the bioconjugation of thiol stabilized CdTe QD for the sensitive detection of methyl parathion (MP) at picogram level. The specificity in the analysis was attributed by highly specific competitive immunological reactions between free MP and CdTe QD bioconjugated MP (MP-BSA-CdTe) for immobilized anti-MP IgY antibodies in a simple flow injection system. We also report the possible resonance energy transfer phenomenon as a result of...

Aquicultura e pesca: a mudança do modelo exploratório.
Provedor de dados: 14
Autores: SANTOS, C.
A pesca é uma das atividades mais antigas da história humana. Sua arte tem sido praticada desde os tempos pré-históricos. Embora não tão antiga quanto a pesca, a aquicultura também é uma arte milenar, os registros apontam essa prática com surgimento entre 4 a 5 mil anos atrás. A pesca e a aquicultura tem relevante papel social, seja de maneira direta ou indireta, pois ambas são meios de subsistência fundamentais de diversas comunidades no mundo todo. Atualmente, com a sobreexploração de diversos estoques pesqueiros e o aumento da população mundial, a demanda por alimentos tornou-se ainda maior. Nesse contexto, a aquicultura surge como o sistema produtivo que poderá repor as perdas da atividade pesqueira, garantido assim a seguridade alimentar do planeta.

There was a lack of up-to-date statistics on the working time requirements in suckler  cattle farming under Swiss production conditions. A combination of final and causal  methods for recording working time was used to determine working-time input and  working-time requirements, to survey influence variables and draw up working-time  models using a model calculation system. The total working time spent on suckler  cattle farming varied between 28 and 120 hours per cow per year, with an average of  66 hours per cow per year. Over half of this time was spent on routine work, 20 % on  management work, 19 % on other non-daily work and 3 % on direct marketing, animal  care and animal handling, respectively. The larger the herd size, the lower the time  spent on...

Up-to-date information on the working-time requirement in pig husbandry and in ecological  pig husbandry in particular which reflects the changed basic conditions in  agricultural practice is extremely rare in the literature. In the Agroscope Reckenholz-  Tänikon ART project Working-Time Requirement in Pig Husbandry according to the  EU Eco-Regulation carried out within the framework of the “Calculation Documents”  work programme of the Association for Technology and Structures in Agriculture  (KTBL), current key figures were provided.  Housing systems and work processes used in pig husbandry vary substantially. For  this reason, two examples commonly used in practice are compared in this article:  outdoor climate housing with two-space pens, and a Pig...

Autores: Moreira,Milene; Baretta,Dilmar; Tsai,Siu Mui; Cardoso,Elke Jurandy Bran Nogueira.
Araucaria angustifolia is an important Brazilian conifer, but it is endangered of extinction due to excessive logging. The objective of the present case study was to survey data on the diversity of AMF in Araucaria angustifolia forests, and to learn whether it is possible to discriminate between the AMF communities associated with natural, introduced, and impacted-by-anthropogenic-action ecosystems. Three ecosystems representative of the Campos do Jordão (São Paulo State, Brazil) region were selected, as follows: (i) a native climax forest, with predominance of Araucaria trees, without anthropogenic interference (NF), (ii) Araucaria forest introduced in 1959 (RE), and (iii) Araucaria forest introduced in 1958, submitted to accidental fire in July 2001...

Autores: Roussel, Erwan; Sauvadet, Anne-laure; Chaduteau, Carine; Fouquet, Yves; Charlou, Jean-luc; Prieur, Daniel; Cambon, Marie-anne.
P&gt;The distribution of the archaeal communities in deep subseafloor sediments [0-36 m below the seafloor (mbsf)] from the New Caledonia and Fairway Basins was investigated using DNA- and RNA-derived 16S rRNA clone libraries, functional genes and denaturing gradient gel electrophoresis (DGGE). A new method, Co-Migration DGGE (CM-DGGE), was developed to access selectively the active archaeal diversity. Prokaryotic cell abundances at the open-ocean sites were on average similar to 3.5 times lower than at a site under terrestrial influence. The sediment surface archaeal community (0-1.5 mbsf) was characterized by active Marine Group 1 (MG-1) Archaea that co-occurred with ammonia monooxygenase gene (amoA) sequences affiliated to a group of uncultured...

Autores: Roussel, Erwan; Sauvadet, Anne Laure; Allard, Jonathan; Chaduteau, Carine; Richard, Pierre; Cambon Bonavita, Marie-anne; Chaumillon, Eric.
In Marennes-Oleron Bay, a macro-tidal bay located on the French Atlantic coast, kilometer-scale acoustic turbidity reveals an accumulation of free gas in the sediment. Large concentrations of organic matter and rapid sedimentation rates provide ideal settings for biogenic methane cycling. We integrate seismic, sedimentologic, biogeochemical and molecular genetic approaches to determine whether microbial methane cycling is involved in this process. Here we show that the acoustic turbidity upper boundary matched with X-ray facies displaying fissures with the highest methane concentrations, demonstrating the existence of methane bubbles in the sediment. 16S rRNA and mcrA gene clone libraries were dominated by sequences affiliated to the three known ANME...

Archeological and mtDNA evidence for Tropical Lowland migrations during the Late Archaic / Formative in northern Chile
Provedor de dados: 97
Autores: ROTHHAMMER,FRANCISCO; SANTORO,CALOGERO M; POULIN,ELIE; ARRIAZA,BERNARDO T; MORAGA,MAURICIO; STANDEN,VIVIEN J.
The influence of tropical lowland migrations on the emergence of cultural change in the Central Andes has been postulated in general terms since the beginning of last century (Tello 1929). Archeological and molecular genetic evidence, particularly agriculture of tropical cultigens and ancient mtDNA haplogroup typing in northern Chile, suggest a chronologically more precise relationship between both regions. We test in this article the hypothesis that the process of cultural transformation of prehistoric populations living on the coast and the desert valleys of northern Chile can be partially linked to gene flow from the eastern slopes of the Andes and/or from the tropical lowlands during the Late Archaic / Formative periods (ca. 3,500-2,000 B.P.).

Are Australian wholesale vegetable markets LOOPy?
Provedor de dados: 31
Autores: Nicols,   Panos; Ahmadi-Esfahani,   Fredoun Z.
Literature regarding the pricing efficiency of Australian wholesale vegetable markets is very limited. The objective of this paper is to test whether or not vegetable products traded in these markets are priced efficiently and satisfy the law of one price (LOOP). To that end, the price relationships between Adelaide and Melbourne markets are tested, using the Johansen cointegration approach, Granger causality and impulse response functions. The empirical findings do not appear to satisfy the LOOP. Policy implications of the analysis are explored.

Are Brazilian corn farmers overconfident about prices?
Provedor de dados: 31
Autores: Cruz Junior,   Jose Cesar.
This paper aims to identify signs of overconfidence among corn producers in south and central-west Brazil. Over the period from October to November 2008, farmers were chosen to answer questions regarding their knowledge of futures markets and price expectations. A large part of subjects responded they do not trade futures contracts because they do not have enough information on the subject. The results show respondents were miscalibrated when estimating directly-stated and the indirectly-stated expected prices. In addition, for certain respondents, subjective variance for corn proves to be significantly less than the market variance. Finally, the paper concludes that the overconfidence effect can partially explain the low use of futures markets by...

Are Consumers Color Blind?: an empirical investigation of a traffic light advisory for sustainable seafood
Provedor de dados: 31
Autores: Hallstein,   Eric; Villas-Boas,   Sofia Berto.
This paper empirically investigates consumer response to a traffic light advisory for environmentally sustainable seafood, which was implemented in the seafood department of a regional supermarket chain in the United States. Green meant 'best choice'; yellow meant 'proceed with caution'; red meant 'worst choice'. Using a unique product-level panel scanner data set capturing sales information for 2 treatment stores and 8 nearby control stores, we apply a difference-in-differences identification strategy to estimate the impact of color-coded labels on consumers' purchases. We find that the advisory leads to no significant difference in total seafood sales. Green sales significantly increase an average of 29% per week; yellow sales significantly decrease an...

Are Consumers in Developing Countries Willing-to-Pay More for Micronutrient-Dense Biofortified Foods? Evidence from a Field Experiment in Uganda
Provedor de dados: 31
Autores: Chowdhury,   Shyamal K.; Meenakshi,   J.V.; Tomlins,   Keith; Owori,   Constance.
Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in pro vitamins A and adapted to local growing environment have the potential to reduce the prevalence of vitamin A deficiency. One such example is the orange-fleshed sweetpotato. However because of its distinctive orange color, which is in contrast to the white varieties that are typically consumed in Africa, it is important to assess whether consumers will accept it.  It is this question that this paper attempts to address, using a choice experiment with the real product to quantify the magnitude of the premium or discount  in consumers’ willingness to pay that may be associated with it.  In addition, it also considers...

Are Corn and Soybean Trend Yields Changing in Illinois?
Provedor de dados: 31
Autores: Sheppard,   Jessica.
Crop yields are influenced by a complex combination of factors, including weather, seed genetics, soil quality, and production management. Regardless, yields still tend to show a general trend over time, which is referred to as the “trend yield.” There has been much debate over whether improved technology has caused trend yields to change in recent years. Many experts believe recent corn yield increases were caused by advancements in biotechnology for seed genetics. It has been suggested that a lack of research on soybean genetics has led to a plateau in the soybean trend yield. It has been widely accepted that these new trends began in the mid-1990s and that they should be used for estimating future yields. However, weather should be taken into...

The role of epiphytes in an intertidal Zostera noltii seagrass bed in Marennes-Oleron Bay was assessed in comparison with the other main benthic primary producers (Z. noltii, microphytobenthos) at two bathymetric levels and on a seasonal basis. Assemblage and biomass of epiphytes were studied using scanning electron microscopy (SEM). Z noltii and its detrital matter followed a typical seasonal pattern: microphytobenthos was present in large quantities throughout the year representing 21% of the total biomass while detrital matter, above-ground parts and below-ground parts accounted for 65, 9 and 5%, respectively. Only two species of epiphytic diatoms, Cocconeis scutellum and Cocconeis placentula, were observed on seagrass leaves. Epiphyte biomass was very...

Provedor de dados: 31
Autores: James,   Harvey S., Jr.; Hendrickson,   Mary K.
In this paper we consider the question of whether middle-scale farmers, which we define as producers generating between $100,000 and $250,000 in sales annually, are better agricultural stewards than small and large-scale producers. Our study is motivated by the argument of some commentators that farmers of this class ought to be protected in part because of the unique attitudes and values they possess regarding what constitutes a “good farmer”. We present results of a survey of Missouri farmers designed to assess farmer attitudes and values regarding a variety of indicators of farmer stewardship, such as the most important issues in agriculture, environment and treatment of farm animals, perspectives on the past and future of agriculture, and ethical...

Despite the speciose fauna of gall-inducing insects in the Neotropical region, little is known about their taxonomy. On the other hand, gall morphotypes associated with host species have been extensively used as a surrogate of the inducer species worldwide. This study reviewed the described gall midges and their galls to test the generalization on the use of gall morphotypes as surrogates of gall midge species in the Brazilian fauna. We compiled taxonomic and biological data for 196 gall midge species recorded on 128 host plant species. Ninety two percent of those species were monophagous, inducing galls on a single host plant species, whereas only 5.6% species were oligophagous, inducing galls on more than one congeneric host plant species.

Autores: Labarta,   Ricardo A.
This paper evaluates farmers’ willingness to pay (WTP) for the vegetative propagated orange fleshed sweetpotato (OFSP) planting material that is many times considered as a public good. Famers’ WTP for OFSP vines was elicited by conducting a real choice experiment (RCE) among 121 small sweetpotato growers in central Mozambique with prior experience growing OFSP but with no participation in OFSP vine distributions in the previous 3 years of the experiment. Results reveals a higher farmers’ willingness to pay for OFSP varieties (US$0.07-0.12) compared to the non-orange planting material (US$ 0.03) and compared to the traditional subsidized price of clean sweetpotato vines (US$ 0.06) used in Mozambique.

Are Staple Foods Becoming More Expensive For Urban Consumers In Eastern And Southern Africa? Trends in Food Prices, Marketing Margins, and Wage Rates in Kenya, Malawi, Mozambique, and Zambia
Provedor de dados: 31
Autores: Mason,   Nicole M.; Jayne,   Thomas S.; Donovan,   Cynthia; Chapoto,   Antony.
The world food and financial crises threaten to undermine the real incomes of urban consumers in eastern and southern Africa. This study investigates patterns in staple food prices, wage rates, and marketing margins for urban consumers in Kenya, Malawi, Mozambique, and Zambia between 1993 and 2009. There is high correlation among wage rate series for various government and private sector categories. We find that average formal sector wages rose at a faster rate than retail maize meal and bread prices in urban Kenya and Zambia between the mid-1990s and 2007. Although the 2007/08 food price crisis partially reversed this trend, the quantities of staple foods affordable per daily wage in urban Kenya and Zambia during the 2008/09 marketing season were still...

Are Traditional Cooperatives an Endangered species? About Shrinking Satisfaction, Involvement and Trust
Provedor de dados: 31
Autores: Nilsson,   Jerker; Kihlen,   Anna; Norell,   Lennart.
Several researchers, who have observed that traditional cooperatives have difficulties in modern markets, mention a number of behavioral concepts characterizing the members. This study attempts to empirically test these concepts. It is based on a survey among members of a large traditional Swedish cooperative. The members perceive the cooperative to be so large and complex that they have difficulties understanding the operations. Hence, they become dissatisfied and uninvolved, and they mistrust the leadership. Moreover, they do not believe that the cooperative can be remodeled to strengthen member control. The findings support the behavioral explanations presented in prior studies.

Are U.S. Corn and Soybeans Becoming More Drought Tolerant?
Provedor de dados: 31
Autores: Yu,   Tian; Babcock,   Bruce A.
An objective drought index that measures the dry and hot conditions adversely affecting crop yields is used in a regression analysis to test whether corn and soybeans have become more drought tolerant. Results indicate that corn yield losses, whether measured in quantity terms or as a percentage of mean yield, have decreased. The null hypothesis that the absolute level of soybean yield losses due to drought has not changed cannot be rejected. But yield losses in percentage terms have decreased over time. Because drought is the primary cause of yield loss in the U.S. crop insurance program and because U.S. crop insurance rates assume that percentage of yield losses are constant over time, these results indicate that U.S. crop insurance rates in the Corn...

The rising obesity during the past three decades poses a severe public health challenge and spurred enormous research interests. This paper contributes to the growing literature on how obesity spreads by empirically investigating whether social norms affect soft drink consumption choices. Combining market level soft drink scanner data and survey data with consumer level characteristics, we employ reduced form regressions to test whether social norms of body weight affects per capita consumption of total or caloric soft drink consumption, on a market level. We also utilize a random-coefficient logit model to examine whether social norms of body weight affect consumer choices on a brand level. Our results from the market level analyses support that a heavier...

Esta pesquisa teve como objetivo obter uma equação, por meio de medidas lineares dimensionais das folhas, que permitisse a estimativa da área foliar de Momordica charantia e Pyrostegia venusta. Entre maio e dezembro de 2007, foram estudadas as correlações entre a área folia real (Sf) e as medidas dimensionais do limbo foliar, como o comprimento ao longo da nervura principal (C) e a largura máxima (L) perpendicular à nervura principal. Todas as equações, exponenciais geométricas ou lineares simples, permitiram boas estimativas da área foliar. Do ponto de vista prático, sugere-se optar pela equação linear simples envolvendo o produto C x L, considerando-se o coeficiente linear igual a zero.

Provedor de dados: 90
Autores: Cessa,Raphael Maia Aveiro; Celi,Luisella; Vitorino,Antonio Carlos Tadeu; Novelino,José Oscar; Barberis,Elisabetta.
A porosidade da fração argila é muito importante para entendimento dos fenômenos físico-químicos que estão relacionados com a área superficial específica das partículas sólidas. Por meio de isotermas de adsorção e dessorção com N2, avaliaram-se a área superficial específica (S BET) e a porosidade das frações argila de Latossolos Vermelhos do Estado de Mato Grosso do Sul, sendo um distroférrico (LVdf) e outro distrófico (LVd), além de caulinita natural (KGa2), goethita (Gt) e hematita (Hm) sintéticas. Resultados referentes à S BET e à porosidade das partículas foram relacionados à adsorção máxima de P (Pmáx) determinada pela isoterma de Langmuir. A classe de poros predominante nas frações argila avaliadas foi de mesoporos. As frações argila extraídas dos...

Armazenamento de sementes de ipê-branco: teor de água e temperatura do ambiente
Provedor de dados: 53
Autores: Martins,Leila; Lago,Antonio Augusto do; Andrade,Antônio Carlos Silva de.
O ipê-branco (Tabebuia roseo-alba) é espécie amplamente utilizada em reflorestamentos mistos destinados à recomposição de áreas degradadas e de preservação permanente, no paisagismo em geral e na construção civil. Suas sementes passam por forte variação na qualidade durante o armazenamento, possuindo período de viabilidade curto, o que representa dificuldades no estabelecimento de técnicas de cultivo e dispersão natural. O objetivo desta pesquisa foi estudar o comportamento fisiológico das sementes de ipê-branco durante o armazenamento. Frutos colhidos manualmente de plantas-matrizes foram colocados em ambiente sombreado para posterior extração das sementes. Após esse processo, foi determinado o teor de água das sementes, removendo-se então, uma amostra...

Provedor de dados: 74
Autores: Lôbo,Ana Maria Bezerra Oliveira; Lôbo,Raimundo Nonato Braga; Paiva,Samuel Rezende.
We determined the polymorphism C242T of the aromatase gene (Cyp19) and its allelic frequency, as well as the effect of the variants on productive and reproductive traits in 71 purebred Santa Inês sheep, 13 purebred Brazilian Somali sheep, nine purebred Poll Dorset sheep, and 18 crossbred 1/2 Dorper sheep. The animals were genotyped using the PCR-RFLP technique. The influence of the animal's genotype on its performance or on the performance of its lambs was analyzed by the least square method. Another factor assessed was the importance of the animal's genotype in analysis models for quantitative breeding value estimates, and whether there were differences among the averages of breeding values of animals with different genotypes for this gene.

Provedor de dados: 87
Autores: Menezes,V.G; Mariot,C.H.P; Kalsing,A; Goulart,I.C.G.R.
O desenvolvimento de genótipos comerciais de arroz resistentes a herbicidas do grupo químico das imidazolinonas proporcionou uma ferramenta eficaz para o controle seletivo do arroz-vermelho (Oryza sativa) em cultivo de arroz irrigado. Contudo, o uso contínuo dessa tecnologia pode favorecer o desenvolvimento de populações de arroz-vermelho resistentes aos herbicidas utilizados para o seu controle. Objetivou-se com este trabalho avaliar a ocorrência de populações de arroz-vermelho resistentes aos herbicidas imidazolinonas, por meio de curvas de dose-resposta, através do fator de resistência (FR). Populações de arroz-vermelho não controladas (escapes) advindas de lavouras de arroz cultivado no sistema Clearfield® no Estado do Rio Grande do Sul foram avaliadas...

Autores: Navone,Graciela T.; Notarnicola,Juliana; Nava,Santiago; Robles,M. del Rosario; Galliari,Carlos; Lareschi,Marcela.
The assemblage of arthropods and helminths, present in sigmodontine rodents (Cricetidae) from a broad wetland area of the Río de la Plata, Argentina, was studied. A total of 250 sigmodontines were captured during a two-year sampling period: Scapteromys aquaticus and Oxymycterus rufus were the most abundant hosts, followed by Oligoryzomys nigripes, Akodon azarae, Oligoryzomys flavescens, and Deltamys kempi. There were 33102 parasites collected, corresponding with Rhopalopsyllidae fleas (Siphonaptera), Hoplopleuridae lice (Phtiraptera), Laelapidae and Macronyssidae mites, Ixodidae ticks, and Trombiculidae chiggers (Acari), the trematodes Echinostomidae, Microphallidae, and Dicrocoelidae, the flatworm Ciclophyllidea, the nematods Trichuridae, Spiruridae,...

Article 82 EC – The Problems and The Solution
Provedor de dados: 31
Autores: Lang,   John T.
The Commission's Guidance paper on exclusionary abuse under Article 82 EC is open to three fundamental criticisms.  First, it leads to less legal certainty, because the rules suggested are vague and imprecise, because dominant companies will not have the information needed to apply them, and because the Commission is trying to change the law, which it has no power to do. Second, it would lead to some anticompetitive effects, because in practice it discourages price competition, by discouraging individualised price negotiations and retroactive rebates, and by suggesting that the Commission will protect not-yet-as-efficient competitors from price competition. Third, it leads to too many "false positives", i.e., findings of exclusionary abuse that are not...

Autores: Kantanen, Juha.
Siberia's last remaining indigenous breed of domestic cattle, the Sakha Ynaga (in Yakutian language), or Yakutan Cattle, inhabit the lands surrounding the Lena River in Russia's remote Sakha Republic (Yakutia). A Finnish multidisciplinary team of researchers from MTT Agrifood Research Finland and the University of Helsinki's Aleksanteri Institute explored the genetic uniqueness of the Yakutian cattle and the effect of social and cultural factors on the survival of the breed through periods of major upheaval in Russia's history. The findings of this study have now been published in the book Sakha Ynaga - Cattle of the Yakuts.

Autores: Borges,Luiz Felipe Kruel; Ferreira,Rogério; Siqueira,Lucas Carvalho; Bohrer,Rodrigo Camponogara; Borstmann,Jacson William; Oliveira,João Francisco Coelho de; Gonçalves,Paulo Bayard Dias.
The aim was to develop a timed artificial insemination (TAI) system in suckled beef cows. Cows (n=227), 60-80 days postpartum, received estradiol benzoate (5mg) and a vaginal device containing 250µg of medroxyprogesterone acetate (MPA; day 0). On day six, cloprostenol (125µg) and eCG (400IU) were administrated and calves were weaned for 88h. The devices were removed on day seven (BioRep group) or on day eight (TAI group). All cows of TAI group and cows of BioRep group that did not exhibit standing estrus received GnRH (100µg) on day 9. In experiment I, the follicular growth was monitored daily by transrectal ultrasound exams, from day 6 to day 9. The average size of the dominant follicle on day nine was 11.1±0.99mm (BioRep, n=7) and 11.5±0.65mm (TAI, n=7)...

A artrografia com duplo contraste é uma técnica de diagnóstico, que prevê a injeção de um meio de contraste positivo (MCP) no espaço articular, seguido de um meio de contraste negativo, a fim de evidenciar lesões nas superfícies articulares e demais estruturas que as compõem. Essa técnica é um procedimento eficaz e minimamente invasivo, já consolidado na medicina humana e na espécie eqüina, com resultados melhores que os obtidos com métodos usuais de diagnóstico. Este trabalho teve como objetivo descrever e avaliar a técnica de artrografia com duplo contraste, aplicada à articulação do úmero de cães, a qual não consta na literatura. O trabalho apresenta a comparação dessa técnica em relação à artrografia com MCP, na avaliação da superfície articular da...

Autores: MEIRA, C. A. A.; RODRIGUES, L. H. A.
A ferrugem do cafeeiro é a principal doença da cultura do café. O conhecimento dos fatores que condicionam as epidemias de ferrugem e a sua previsão são importantes. Uma instância do processo de descoberta de conhecimento em bases de dados foi realizada para avaliar a aplicação de árvores de decisão na análise e no alerta da ferrugem. As classes do atributo meta foram definidas por intervalos da taxa de progresso da doença. Dados meteorológicos, a carga pendente de frutos e o espaçamento entre plantas serviram de atributos preditivos. As árvores de decisão obtidas auxiliaram na compreensão de quais variáveis, e como as interações dessas variáveis, conduziram a ferrugem no campo. O modelo de alerta para lavouras com alta carga pendente de frutos apresentou...

ASCAT/MetOp scatterometer data : first results for sea ice study
Provedor de dados: 5
Autores: Ardhuin, Fanny; Ezraty, Robert; Croize-fillon, Denis.
Backscatter values from scatterometers are commonly  used to estimate wind field over oceans, their ability to  monitor sea ice coverage, age and drift has been also  demonstrated. Here, ASCAT backscatter coefficient has  been processed for sea ice geophysical interpretation in  order to increase the long time series of ice parameters  already available. It has been shown that incidence- adjustment is mandatory for geophysical meaning, the  backscatter maps enable the discrimination between  multi year ice and first year ice, these maps can also be  used as a basic product for sea ice drift estimation.

In order to sustain the growing interest in the consumption of pitaya cactus (Stenocereus stellatus Riccobono) fruit as potential neutraceutical food, the total phenolics and ascorbic acid contents were determined in four pitaya cactus fruit types (red, cherry, yellow and white). Total phenol and ascorbic acid concentrations were correlated to the antioxidant capacity (fimol Trolox eq g-1 fresh sample). The results showed that the white and yellow types contained a higher amount of phenol compounds and ascorbic acid than the cherry and red types. A linear relationship was found between the fruit antioxidant capacity and the total phenol content (R²=0.97) and ascorbic acid content (R²=0.79), indicating that both of them contribute together to its...

Autores: Sapoznikow,Alexandra; Quintana,Flavio.
Durante las temporadas reproductivas 2001 y 2002 se estudió la biología reproductiva del Cormorán Cuello Negro (Phalacrocorax magellanicus) en Punta Loma, Chubut, Argentina. Los cormoranes presentaron un periodo de puesta prolongado (3-4 meses) con una alta asincronía de puesta y un bajo éxito de volantones (cercano al 50%). En la primera temporada, el número de pichones independizados por nido fue independiente de la fecha de puesta, mientras que en la segunda se observó una disminución del número de pichones independizados cuando las puestas se realizaron hacia el final del período reproductivo. Un alto porcentaje de parejas repuso su nidada en ambos años (16-22%). El número de pichones independizados por nido en la segunda puesta fue similar al de la...

Asociación entre indicadores de estabilidad estructural y la materia orgánica en suelos agrícolas de Venezuela
Provedor de dados: 115
Autores: Pulido-Moncada,Mansonia A.; Lobo-Luján,Deyanira; Lozano-Pérez,Zenaida.
La estabilidad estructural de los suelos depende de varios factores y su evaluación se hace con diversos métodos e índices de predicción. Uno de los indicadores es la materia orgánica del suelo (MOS), ya que ayuda a mantener las partículas minerales unidas frente a las fuerzas desestabilizadoras como el humedecimiento e impacto de gotas de lluvia. Sin embargo, los estudios realizados han enfatizado la relación entre estabilidad de agregados y el contenido de MOS, sin considerar su tipo o calidad. Por tanto, en el presente estudio se evaluó la asociación entre la calidad y contenido de MOS y la estabilidad estructural de la capa superficial en cinco suelos agrícolas de Venezuela. Con un muestreo dirigido aleatorio simple se seleccionaron nueve puntos de...

Asociaciones de productores y su contribución al desarrollo económico local : el sector de plantas ornamentales en el Estado de Morelos
Provedor de dados: 122
Autores: Tapia Téllez, Gabriela.
El logro de bienestar a través de un empleo estable y bien remunerado, se ha convertido para muchos, en una utopía al pasar los años como consecuencia de la situación económica en la que se desenvuelven actualmente los países. En respuesta a ello, desde la década de los ochenta, el desarrollo económico local se ha perfilado como una de las áreas con mayores aportes en este sentido, con investigaciones sobre el fomento del empleo a través de iniciativas locales, como lo son las asociaciones de productores, objeto de estudio de esta investigación.

Aspectos ecológicos da determinação sexual em tartarugas
Provedor de dados: 36
Autores: Ferreira Júnior,Paulo Dias.
Os aspectos ecológicos relacionados à reprodução das tartarugas e de outros répteis que apresentam determinação sexual dependente da temperatura de incubação desempenham um papel crucial no equilíbrio das populações. Nestas espécies a razão sexual dos filhotes é controlada pela temperatura a que os ovos são submetidos durante a incubação. Entender como as características do local da desova afetam a temperatura da incubação é essencial para que se possa argüir sobre os fatores que controlam a ecologia, a reprodução e a distribuição geográfica das tartarugas. Este trabalho de revisão aborda o modo de reprodução das tartarugas e a maneira como a reprodução é afetada pelo meio físico.

A porosidade do solo é de extrema importância à produtividade agrícola, uma vez que, em condições adversas, pode dificultar a penetração das raízes e, consequentemente, limitar o adequado aproveitamento dos nutrientes e da água disponível. Na Fazenda Bonança, em Pereira Barreto - SP, em 2005, foi analisada a produtividade de forragem do milho (MSF), a macroporosidade (MA), a microporosidade (MI) e a porosidade total (PT) de um Latossolo Vermelho distrófico (Acrustox Háplico), sob plantio direto, em três profundidades. O objetivo foi estudar as correlações lineares e espaciais entre os atributos da planta e do solo, na tentativa de selecionar, entre os do solo, um indicador da sua qualidade física de boa representatividade para a produtividade da forragem....

Autores: Freitas,S.H.; Evêncio Neto,J.; Dória,R.G.S.; Mendonça,F.S.; Simões,M.J.; Camargo,L.M.; Sebe,A.A.
Avaliaram-se as alterações morfológicas, morfométricas e ultraestruturais que ocorreram no baço devido à isquemia produzida pelo clampeamento total do pedículo hepático. Para tanto, foram utilizados 40 ratos machos, distribuídos em quatro grupos de 10 animais. O grupo-controle (C) não foi submetido à isquemia, e os grupos tratados (E1, E2e E3) foram submetidos ao clampeamento por 10, 20 e 30 minutos, respectivamente. Fragmentos do baço foram retirados e analisados histologicamente pela microscopia de luz (hematoxilina-eosina, ferrocianeto-férrico) e pela microscopia eletrônica de transmissão. Os resultados demonstraram que 10 minutos de clampeamento do pedículo hepático são suficientes para apresentar sinais de congestão esplênica e 20 e 30 minutos...

Aspectos relacionados à presença de fungos toxigênicos em uvas e ocratoxina A em vinhos
Provedor de dados: 65
Autores: Welke,Juliane Elisa; Hoeltz,Michele; Noll,Isa Beatriz.
A colonização dos Aspergillus da secção Nigri nas uvas durante o cultivo é a principal fonte de ocratoxina A (OTA) nos vinhos. A. carbonarius e A. niger são os principais produtores desta micotoxina em uvas e são fungos oportunistas que, se desenvolvem, principalmente, nas bagas danificadas durante seu amadurecimento. A produção de OTA em uvas é influenciada pelas condições climáticas e áreas geográficas, bem como pela variedade de uva, pelo sistema de cultivo e pelos danos causados nas uvas por insetos, infecção fúngica ou excesso de irrigação e chuva. As medidas para o controle de fungos toxigênicos devem considerar esses pontos críticos de controle. A OTA presente nas uvas é transferida para o vinho durante o processo de vinificação, sendo que um...

Assemblage-structuring force of species interactions varies spatially and temporally: Co-occurrence analysis of canopy arthropod distributions
Provedor de dados: 17
Autores: Matthew K. Lau; Laura E. Hagenauer; Thomas G. Whitham.
*Background/Question/Methods* Understanding how interactions amongst species contribute to their distribution is central to community ecology. However, it is not understood how these processes may change under different environmental conditions. In this study, we present evidence that suggests interactions amongst canopy arthropods contribute to assemblage structure, depending on both the sampling time and location. We sampled canopy arthropod species abundances on individual trees in three adjacent, monospecific stands of Populus fremontii (Fremont cottonwood), which differ in planting year (2000, 2002, 2005). We then conducted null-model based co-occurrence analysis using the freely available software EcoSim (Kesey-Bear and Acquired Intelligence, Inc.)...

Assessing a treatment on the basis of an individual or a group. An example: the homeopathic treatment of digestive-tract strongyles in sheep
Provedor de dados: 21
Autores: TABEL, J.; SAUVE, C.; CORTET, J.; TOURNADRE, H.; THOMAS, Y.; CABARET, J.
Homeopathic treatments, widely used in organic farming, remain unevaluated. Assessment is difficult since the individuals that respond to treatment are not identified, although it is central to the concept of homeopathic treatment. Classifying lambs into those to be treated (since they have high parasitic infection rate or poor production performances) or that should remain untreated (in other words, even when treated, they will not benefit from treatment) is not simple. The identification of lambs to be treated can be based on parasitological examinations (eggs per gram of faeces), clinical (anaemia or diarrhoea)or production-related (weight gain) results. The classification of lambs was a posteriori and based on dendrograms using UPGMA (unweighted...

Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.; Hansen,   James M.; Matthey,   Holger; Pan,   Suwen; Tuan,   Francis C.
A team of U.S. analysts visited China to assess the potential for use of distillers dried grain plus solubles (DDGS) in China’s livestock sector. They examined the economics of the use of DDGS in feeds, the policy issues surrounding the use of the product, and transportation-logistic constraints in the expansion of DDGS imports. The team collected actual and secondary data to conduct a micro-economic analysis of the impact of DDGS on feed cost, solicited official and expert opinions through interviews, and conducted site visits. They found the development of the DDGS import market in China to be very promising. The microeconomic analysis showed a clear economic incentive for feed millers and livestock producers to use DDGS in their feed ration, with a...

Provedor de dados: 16
Autores: Chua, L.S.L.; Kiew, R.; Chan, Y.M.
Following the revision of Peninsular Malaysian Begonia, a project that involved extensive fieldwork, we now have sufficient data to assess their conservation status. Out of 54 taxa, 48 are endemic to Peninsular Malaysia. No fewer than 30 taxa are known from fewer than five localities; 24 taxa are Critically Endangered (CR), 3 are Endangered (EN) while 4 are Vulnerable (VU). One taxon is Extinct (EX), the 22 remaining are Near Threatened (NT), Least Concern (LC) and Data Deficient (DD). We discuss how the assessment was carried out and the implications for the long-term conservation of Begonia. The most significant conservation measure proposed here is the gazettement of limestone hills as totally protected areas.

Assessing Consumer Preferences and Attitudes toward Imported Pork in Urban China
Provedor de dados: 31
Autores: Ortega,   David L.; Wang,   H. Holly; Wu,   Laping.
China’s transition into a developed economy is driving changes in consumer preferences and demand for foods. To evaluate consumer preferences for imported pork in urban China, primary data were collected in two metropolitan areas- Beijing and Shanghai. Estimated logit models revealed that an individual’s age, shopping location and food safety concerns significantly influenced their willingness-to-pay for U.S. pork. A proportional linear model was developed to evaluate factors affecting purchasing behavior of western-style pork cuts vs. traditional Chinese cuts. Food safety concerns were linked to a previous lean-meat additive scare and a lack of consumer confidence on the Chinese food inspection system.

Provedor de dados: 31
Autores: Jabbar,   Mohammad A.; Admassu,   Samuel A.
Conjoint analysis was applied to asses the part worth of beef quality and safety attributes using a cross sectional data from a stratified sample of 300 households in Addis Ababa city collected in June 2007. Due to the absence of official standards for quality and safety in the domestic market for beef, information on consumer perception on quality and safety attributes were derived from a rapid appraisal. These were then used for defining product profiles in the detailed survey. Results show that, freshness, abattoir stamp, fat content, hygiene of meat shop and staff, and price are significant quality and safety attributes that consumers use, in the order mentioned, in their beef purchase decisions. There are differences in the relative importance of...

Assessing potential efficiency gains in irrigated water use in New Zealand.
Provedor de dados: 31
Autores: Ford,   Stuart; Harris,   Simon; Doak,   Murray.
This paper reports a research project carried out on behalf of the Ministry of Agriculture and Forestry New Zealand designed to scope the issue of water efficiency in New Zealand and demonstrate where the most significant gains in efficiency can occur. The paper describes the efficiency framework developed based on the key areas of allocative, technical and dynamic efficiency. The areas of significant gains based on the theoretical analysis are tested against three community irrigation schemes. Although the case study findings support the theoretical conclusions there is a significant range of potential areas of improvement according to the nature of each case study.

Assessing programmes for the provision of agri-environmental services               – An efficiency analysis realized in Southern Germany
Provedor de dados: 31
Autores: Kantelhardt,   Jochen; Eckstein,   Karin; Hoffmann,   Helmut.
Agricultural land use does not only concern farmers, but is of high relevance for the environment. Agri-environmental programmes aim to foster the environmental soundness of agricultural production. The aim of this study is to analyse the impact of agri-environmental programmes on the economic and the environmental performance of farms. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the environmental efficiencies of farms and examined whether farms are able to succeed in combining environmental and economic efficiency. As study object serves a South German agri-environmental programme, the Bavarian KULAP. A farm survey was conducted covering a total of 102 farmers. The results show that farmers who...

Autores: Moon,   Wanki; Griffith,   Wayne.
This study used the contingent valuation method to shed light on public preferences on the multifunctional roles of the U.S. agriculture and to present a holistic estimate of the economic value of the nonmarket goods and services of the U.S. agriculture.  Fishbein’s model of reasoned behavior and mediation hypothesis were combined to model the relationship between WTP (behavioral intentions) and sets of explanatory variables including attitudes, perceived attributes (about family farms, farmland preservation programs, government involvement in agricultural markets, and ecological state of our world), and socio-demographic profiles.  The estimated mean WTP was $515 per taxpayer annually.  Aggregating individual WTPs across the U.S. taxpayers above 20 years...

Assessing the Demand for a Functional Food Product: Is There Cannibalization in the Orange Juice Category?
Provedor de dados: 31
Autores: Yuan,   Yan; Capps,   Oral, Jr.; Nayga,   Rodolfo M., Jr.
The demand for functional foods has increased notably in recent years due to growing consumer interest in diet and health issues. Currently, the food industry is introducing many types of new food products with functional attributes. Consequently, cannibalization is a critical issue for firms that offer multiple products within a certain product category. The identification and assessment of cannibalization are integral factors when making strategic decisions about new product introductions. Using scanner data from Information Resources, Inc. (IRI), pertaining to a particular functional food, namely a phytosterol-enriched product for orange juice, we find that no cannibalization effects exist with respect to its introduction. We also provide estimates of...

Assessing the ecological soundness of organic and conventional agriculture by means of life cycle assessment (LCA) - a case study of leek production
Provedor de dados: 21
Autores: de Backer, Eline; Aertsens, Joris; Vergucht, Sofie; Steurbaut, Walter.
Purpose – Sustainable agriculture implies the ability of agro-ecosystems to remain productive in the long-term. It is not easy to point out unambiguously whether or not current production systems meet this sustainability demand. A priori thinking would suggest that organic crops are environmentally favourable, but may ignore the effect of reduced productivity, which shifts the potential impact to other parts of the food provision system. The purpose of this paper is to assess the ecological sustainability of conventional and organic leek production by means of life cycle assessment (LCA).     Design/methodology/approach – A cradle-to-farm gate LCA is applied, based on real farm data from two research centres. For a consistent comparison, two functional...

Assessing the economic impact of redistributing water within a catchment: A case study of the Musi Catchment in the Krishna Basin in India
Provedor de dados: 31
Autores: Davidson,   Brian; Hellegers,   Petra J.G.J.; Samad,   Madar.
The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be...

This paper demonstrates a comprehensive methodology to assess the viability of an environmental management plan which has long-run economic and ecological impacts. The case study under consideration is the implementation of a water resource management plan in a water scarce region of the world, namely Cyprus. Specifically this plan proposes to replenish a depleting aquifer with treated wastewater. The methodology proposed first identifies the key stakeholder groups, namely farmers and the general public, who are hypothesized to derive economic values (benefits) from the implementation of this plan, and then implements stated preference methods to capture the total economic value of these benefits. Benefits are aggregated over the relevant populations of...

Assessing the environmental externalities from biofuels in Australia
Provedor de dados: 31
Autores: Cuevas-Cubria,   Clara.
In Australia, as in other countries, the environmental costs and benefits of biofuel production and use have been found to vary greatly according to the production method and feedstocks used. In general, the use of biodiesel produced in Australia has been found to provide greater environmental benefits than ethanol, both in terms of reduced greenhouse gas (GHG) emissions and reduced air pollutant emissions. In this paper, estimates of GHG and air pollutant emissions arising from biofuels and petroleum fuels production and use are employed to calculate the change in environmental externalities when substituting biofuels for petroleum fuels in Australia. These estimates of externalities highlight the need to better understand the environmental implications...

Assessing the Genotypic Differences for Seed Set and Seed Abortion in Tomato Genotypes
Provedor de dados: 17
Autores: Chalapathy  K. Reddy; Ganeshaiah Narayana; Uma  Shaanker.
Tomato (_Lycopersicon esculentum_ Mill.) is one of the most popular fruit vegetable around the world. Seed abortion where in only a small proportion of ovules in an ovary develops into matured seeds, is a wide spread phenomenon in multi-ovulated species. In agriculturally important crops such as chickpea, groundnut, Brassica, pigeon pea and field bean seed abortion substantially reduces their productivity. Tomato genotypes exhibited seed abortion where in only some proportion of ovules developed into matured seeds. Seed abortion in tomato cultivars would increase the cost of hybrid seed production. In this study, we have analyzed 19 genotypes for number of ovules, seed set and seed abortion. Tomato genotypes differed significantly for number of ovules per...

Provedor de dados: 31
Autores: Liebenehm,   Sabine; Affognon,   Hippolyte; Waibel,   Hermann.
Ex-post evaluation of agricultural research is aimed to empirically provide evidence of past investments’ effectiveness. This paper is intended to measure the immediate impact of livestock research activities on cattle farmers’ knowledge about trypanosomosis and its therapeutic and preventive control strategies. According to the quasi-experimental design of the intervention, it is shown that its impact will be adequately estimated by propensity score matching (PSM). Based on data collected according to a knowledge, attitude and practice (KAP) questionnaire in the region of Kénédougou that is common to Mali and Burkina Faso, results indicate a significant gain in farmers’ know-how due to participation in livestock research activities.

Provedor de dados: 31
Autores: Macagno,   Giulia; Loureiro,   Maria L.; Nunes,   Paulo A.L.D.; Tol,   Richard S.J.
This analysis provides an example of how biodiversity can be measured by means of different indicators, and how the latter can be used to assess the influence of the biodiversity profile of a region on the tourism flows towards it. Previous studies have considered environmental amenities as one of the determinants of tourism destination choice. The central hypothesis of this paper is that the destination’s biodiversity profile can be considered as a key component of environmental amenities. The main objective of this study is to propose a different perspective on this topic, considering the role of biodiversity on tourists’ choice of destination and duration of stay. Domestic Irish tourist flows have been chosen as a case study. The first step of the...

Payment for environmental services (PES) is a promising mechanism for conservation. It also has the potential to contribute to social objectives such as poverty reduction. To promote synergy in the implementation of PES, however, a number of conditions on spatial, economic, ecological, and institutional feasibilities are essential. This study discusses factors affecting the synergy prospect of PES and provides a simple framework for assessing the potential for synergy in the implementation of PES, focusing on spatial correlation of thematic areas and funding availability for payments. We apply the framework to an empirical analysis of the “water funding” in Costa Rica, a new conservation financing source generated by water tariff revenue and will be...

Assessing the Returns from Organic Marketing Channels
Provedor de dados: 31
Autores: Park,   Timothy A.
Organic farmers face heightened pressure in developing a portfolio of different marketing channels and in bargaining competitively with increasingly sophisticated marketing participants in the supply chain for organic products. This research assists producers by identifying specific farm and demographic factors that enhance earnings given the choice of marketing outlet. The two significant selectivity coefficients confirm that organic earnings when marketing through a single outlet are biased upward since farmers who are better suited to market through multiple outlets have already moved away from this marketing strategy. An accurate evaluation of the projected earnings from any marketing strategy must account for selectivity effects.

Assessing the Uncertainty of Land Based Carbon Sequestration: A Parameter Uncertainty Analysis with a Global Land Use Model
Provedor de dados: 31
Autores: Kim,   Yoon Hyung; Sohngen,   Brent.
This paper analyzes the effect of uncertainty in several key parameters on the marginal costs of carbon sequestration in forests. These parameters include the land supply elasticity, which governs the conversion of land from agriculture to forests and vice versa; parameters of the forest biomass yield function; parameters of the forest carbon density function; and parameters of the costs functions for accessing inaccessible land. Monte Carlo techniques are thus used to turn the global forest model with no probability (e.g., Sohngen &amp; Mendelsohn, 2003; 2007) into a proper probability model through Latin hypercube sampling.       For this paper, we have restricted our analysis to consideration of probability distributions for only two of the parameters...

Assessing varietal resistances to control common wheat bunt under organic cereal production and soft wheat, in particular
Provedor de dados: 21
Autores: FONTAINE, L.; du CHEYRON, P.; MORAND, P.; SKIKERS, S.
Common wheat bunt (caused by the fungus Tilletia caries or Tilletia foetida) is a disease whose incidence is clearly on the rise in organic farming, jeopardising the balance of the French organic cereal sector. Control methods adapted to organic farming must be found, especially since we know that no seed treatment is 100% effective. The use of varietal resistance appears particularly promising for limiting the spread of the disease. Since 2000, an experiment whose purpose is to assess the resistance of soft wheat varieties to Tilletia caries is conducted each year by the French plant institute, ARVALIS. These experiments make it possible to identify the existence of a wide behavioural variability with respect to this pathogen among the different varieties...

Spain is the most arid country in Europe and water use as well as water depletion and environmental degradation have slowly become a matter of social concern. Balancing the two objectives of “water for rural livelihoods” and “water for nature” constitutes a difficult challenge for the water Administration. The aim of this paper is to analyze the impact of water conservation policies in the Upper Guadiana River basin (Spain), where intensive irrigated agriculture resulted in the overexploitation of the Western La Mancha aquifer and the subsequent degradation of the highly valuable wetlands. Focus is made on farmers’ vulnerability to these policies. The methodology combines qualitative and quantitative aspects by the integration of an economic model and a...

Autores: Rigouin, Coraline; Delbarre Ladrat, Christine; Sinquin, Corinne; Colliec-jouault, Sylvia; Dion, M.
To find biocatalyst allowing depolymerization of new polysaccharides, one needs to get a sensitive and well adapted method to a screening program. This led us to compare biochemical methods of detection of the depolymerization. Currently used methods such as reducing sugars assays, double bond monitoring or molecular weight determination were tested to follow the kinetic of depolymerization with different enzyme / polysaccharide couples. The range of concentrations of assorted enzymes allowed us to identify the most sensitive and appropriate method to detect polysaccharide degradation. Reducing sugars assays are quantitative, sensitive and almost usable with all kind of polysaccharide but some compounds may interfere with them. When polysaccharide is...

Autores: Baigún,Claudio R. M.; Colautti,Darío C.; Grosman,Fabian.
The pejerrey Odontesthes bonariensis is the most important target species in temperate freshwater fisheries of Argentina, and assessment of condition has been a regular practice and common diagnostic tool. Most pejerrey fishery studies have used Fulton's (K) index, without testing whether underlying assumptions or requirements were met. We analyzed and contrasted the applicability of K, Kn and Wr indices to assess condition status in several pejerrey populations inhabiting Pampean lakes. Our results showed that whereas Wr and Kn displayed significant condition changes across length at some study lakes, Kn portrayed a small range of variation. We also noted that pejerrey maximum length and size structure strongly varied among populations probably due to the...

Assessment of ecological risk to populations of aquatic invertebrates
Provedor de dados: 13
Autores: Tsytsugina, V. G.
On the base of experimental data and cytogenetic studies of marine and freshwater invertebrates natural populations it was shown that different species had approximately equal part (%) of full value posterity at the same average level of chromosome mutagenesis for populations, independing on deleterious factors and females fecundity. This phenomenon made it possible to calculate specimens reproductive contribution for species with different females fecundity and to assess expected reduction of population adaptive potential and the increase of ecological risk at different levels of population damage. It is suggested that the adaptation to pollution will be more effective in populations with high female fecundity.

EST-SSR markers were used to investigate the genetic diversity among and within coffee populations, to explore the possibility of their use for fingerprinting of cultivars and to assist breeding programs. Seventeen markers, developed from ESTs (Expressed Sequence Tags) from the Brazilian Coffee Genome Project, were used. All markers showed polymorphism among the genotypes assessed. The average number of allele per primer was 5.1. The highest polymorphisms were found within C. canephora (88.2%) and rust-resistant varieties (35.3%). About 29.4% of the markers differentiated C. arabica from Híbrido de Timor; it was also possible to identify those closest and farthest from C. arabica .

Since recent decades, nutrient-related eutrophication, originating from agricultural use of fertilizer and population enhancement, can be considered worldwide as the main disturbance for coastal lagoons. Since coastal lagoons are very shallow and enclosed, their functioning is tightly linked to meteorological conditions. The aim of this study is to compare different rainfall levels and eutrophication response on coastal lagoons of the Languedoc-Roussillon (Western Mediterranean coast), subject to different nutrient loads from their watershed, in order to check the possibility to distinguish the effects of watershed management or rainfall conditions on water quality (waste water treatment plant improvement, decrease of fertilizer spreading).

Assessment of impacts from human activities on ecosystem components in the Bay of Biscay in the early 1990s
Provedor de dados: 5
Autores: Lorance, Pascal; Bertrand, Jacques; Brind'Amour, Anik; Rochet, Marie-joelle; Trenkel, Verena.
The ecosystem-based approach to fisheries management and, more specifically, the European Marine Strategy Framework Directive require the assessment of the state and dynamics of an ecosystem in order to determine suitable management strategies. This paper takes an analytical approach to assess the state of the Bay of Biscay ecosystem in the early 1990s, chosen as a period of reference because key monitoring data series have been collected since then. To assess the state of the ecosystem, the pressures exerted by six broad categories of human activities were examined. A literature review of the ecosystem components was made and a component tree was tailored according to data availability. Data rich components were subdivided into subcomponents for their...

Provedor de dados: 60
Autores: Vicentini,Fabiana Testa Moura de Carvalho; Georgetti,Sandra Regina; Bentley,Maria Vitória Lopes Badra; Fonseca,Maria José Vieira.
To be effective against the oxidative damages induced by UVB irradiation in the skin, the drug needs to release from the formulation in which it was incorporated and reach the skin layers where the ROS are generated. Thus, it is very important the development of a robust and sensitive methodology to extract and quantify in different skin layers the antioxidant agent delivered from topical formulations. Therefore, in the present work suitable methods to extract and quantify quercetin in skin samples and receptor phase after in vitro penetration studies were developed. The results demonstrated that the recovery from two different layers of skin, the SC and [E+D], using two different methods of quantification (DPPH• assay and HPLC, respectively), was 93.8 %...

Assessment of the ecological status of coastal areas and estuaries in France, using multiple fish-based indicators: a comparative analysis on the Vilaine estuary
Provedor de dados: 5
Autores: Brind'Amour, Anik; Lobry, Jeremy.
When reviewing the various fish-based community indicators aiming at assessing the ecological status of marine communities and/or ecosystems, a typology consisting of three major components emerges. The first component highlights the choice of relevant metrics associated with a level of organization (e. g. population or community). The second relies on the method used to combine the metrics (an aggregated indicator or a synoptic table). The third refers to the type of analysis (direct or indirect) that is used to establish the link between the metrics and a given pressure. In this paper we use the Vilaine coastal-estuarine fish communities as a case study to discuss and relate two different approaches to the suggested typology. The first approach...

Assessment of the origin of microbiological contamination of groundwater at a rural watershed in Chile
Provedor de dados: 115
Autores: Valenzuela,Mariela; Mondaca,María A.; Claret,Marcelino; Pérez,Claudio; Lagos,Bernardo; Parra,Oscar.
In a rural watershed in Chile, the scarce groundwater available represents almost the only water source both for agriculture and domestic use. This water has microbiological quality problems, which result in an agricultural and local economic development constraint. Contamination can come from punctual or diffuse sources. Characterizing the microbiological quality of groundwater allows both to identify sources from the point of view of whether they are point or non point -thus facilitating their reduction or elimination- and to determine health hazards likely to affect the population in the area under study. This study aimed to improve the state of knowledge on the microbiological quality of groundwater at a rural watershed. Forty two wells were seasonally...

Autores: Faria,Danielle Assis de; Peixoto,Jane de Oliveira; Lopes,Paulo Sávio; Paiva,Samuel Rezende; Silva,Priscila Vendramini; Guimarães,Simone Eliza Facioni.
This study investigated the association between IGF-I microsatellite marker in an F2 population (N=459) generated by mating of native boars to Brazilian commercial sows with performance, carcass cut, and meat quality traits. Association analyses were carried out using a statistical model that included genotype, sex, and group as fixed effects and sire as random effect. The IGF-I genotypes were significantly associated with different quantitative traits and these results corroborate with previous QTL analyses obtained for this chromosome region in swine. Additive and dominance effects, as well as a genotype-sex interaction, were estimated and discussed in the text. According to the results obtained, this marker is suitable for QTL search in the genotyped...

Autores: Peixoto,Jane de Oliveira; Faria,Danielle Assis de; Silva,Priscila Vendramini; Fonseca,Isabela; Lopes,Paulo Sávio; Guimarães,Simone Eliza Facioni.
It was investigated the association between leptin gene single nucleotide polymorphisms (SNPs) T2411C and T3266G with carcass traits in F2 pigs obtained by crossing native Brazilian Piau with commercial sows composed of Landrace, Large White and Pietrain breeds. Association analyses were performed using a statistical model that included genotype, sex, and batch as fixed effects, sire and error as random effects. The T2411C SNP was associated with skinless and fatless boston shoulder weight (BSW), backfat thickness at last rib, 6.5 cm from the midline (P2), skinless and fatless picnic shoulder weight, and sirloin weight (SLW). The T3266G mutation was associated with slaughter age, bacon weight, BSW, midline backfat thickness between last and last but one...

Angiotensin-converting enzyme (ACE) activity and polymorphism contribute significantly to the prognosis of patients with cardiomyopathy. The aim of this study was to determine the activity and type of ACE polymorphism in patients with familial and nonfamilial hypertrophic cardiomyopathy (HCM) and to correlate these with echocardiographic measurements (echo-Doppler). We studied 136 patients (76 males) with HCM (69 familial and 67 nonfamilial cases). Mean age was 41 ± 17 years. DNA was extracted from blood samples for the polymerase chain reaction and the determination of plasma ACE levels. Left ventricular mass, interventricular septum, and wall thickness were measured. Mean left ventricular mass index, interventricular septum and wall thickness in familial...

We investigated the effect of the -278A&gt;C polymorphism in the CYP7A1 gene on the response of plasma lipids to a reduced-fat diet for 6 to 8 weeks in a group of 82 dyslipidemic males with a mean age of 46.0 ± 11.7 years. Individuals who presented at least one high alteration in total cholesterol, low-density lipoprotein cholesterol or triglyceride values were considered to be dyslipidemic. Exclusion criteria were secondary dyslipidemia due to diabetes mellitus, renal, liver, or thyroid disease. None of the subjects were using lipid-lowering medication. Baseline and follow-up lipid concentrations were measured. The genotypes were determined by the digestion of PCR products with the BsaI restriction endonuclease. There were statistically significant...

Autores: Freitas,H.F.G.; Barbosa,E.A.; Rosa,F.H.F.P.; Lima,A.C.P.; Mansur,A.J.
It has been demonstrated that there is an association between serum lipoproteins and survival rate in patients with ischemic cardiomyopathy, as well as in patients with non-ischemic causes of heart failure. We tested the hypothesis of an association between serum lipoprotein levels and prognosis in a cohort of outpatients with heart failure, including Chagas' heart disease. The lipid profile of 833 outpatients with heart failure in functional classes III and IV of the New York Heart Association, with a mean age of 46.9 ± 10.6 years, 655 (78.6%) men and 178 (21.4%) women, was studied from April 1991 to June 2003. The survival rate was estimated by the Kaplan-Meyer's method and the Cox proportional hazards models. Etiology of heart failure was ischemic...

Asteraceae visited by honeybees in Argentina: a record from entomopalynological studies
Provedor de dados: 51
Autores: Telleria,María C.
Entomopalynological studies of Asteraceae in Argentina revealed that 64 taxa occurred in food stored by honeybees. The most visited plant tribes were classified according to both the type of reward provided by the different taxa and the intensity that such reward is collected by honeybees. Exotic plant taxa were intensely visited inside the disturbed areas (e.g. Cardueae and Cichorieae tribes), whereas native taxa (e.g. Barnadesioideae, Mutisieae, Astereae and Eupatorieae) were intensely visited in less disturbed areas. A large number of identified taxa of Asteraceae and the evaluation of its importance to honeybee nutrition were presented. The present study contributes to the knowledge of relationship between Asteraceae and honeybees.

Astyanax ajuricaba: a new species from the Amazon basin in Brazil (Characiformes: Characidae)
Provedor de dados: 83
Autores: Marinho,Manoela M. F.; Lima,Flávio C. T.
A new Astyanax species is described from several localities in the rio Negro, rio Solimões and lower rio Tapajós basins, Amazon basin, Brazil. The new species is distinguished from all remaining characids by its unique color pattern consisting of the combination of presence of a conspicuous, narrow dark midlateral stripe, a well-developed vertically-elongated dark humeral spot, and upper caudal-fin lobe and middle caudal-fin rays dark, with a rounded clear ocellated spot present at anterior third of caudal-fin lobe.

Astyanax hastatus Myers, 1928 (Teleostei, Characidae): a new species complex within the genus Astyanax?
Provedor de dados: 74
Autores: Kavalco,Karine Frehner; Brandão,Karina de Oliveira; Pazza,Rubens; Almeida-Toledo,Lurdes Foresti de.
Four populations of Astyanax hastatus Myers 1928 from the Guapimirim River basin (Rio de Janeiro State) were analyzed and three distinct cytotypes identified. These cytotypes presented 2n = 50 chromosomes, with 4M+8SM+10ST+28A (Cytotype A), 8M+10SM+14ST+18A (Cytotype B), 6M+8SM+4ST+32A (Cytotype C) and scanty heterochromatin, mainly located throughout pericentromeric regions of several chromosomal pairs. No homologies with the As-51 satellite DNA were observed in the three cytotypes, although all of them presented multiple 18S rDNA sites, as detected by both silver nitrate staining and FISH (fluorescent in situ hybridization). The application of the term "species complex" in Astyanax is discussed from a cytotaxonomic viewpoint.

Provedor de dados: 83
Autores: Alcaraz,Héctor S. Vera; Pavanelli,Carla S.; Bertaco,Vinicius A.
Astyanax jordanensis, new species, is described from the rio Jacu and rio das Torres, both tributaries to the lower rio Jordão, in the rio Iguaçu basin, Paraná, Brazil. The new species is a member of the A. scabripinnis species complex. Astyanax jordanensis differs from its congeners by several meristic and morphometric characters. Mature males possess bony hooks in the dorsal, pectoral, pelvic, and anal fins, and mature females have a few small bony hooks on the first rays of the anal fin. The presence of these bony hooks in females and the endemism of the ichthyofauna in the rio Jordão are discussed.

Asymmetric development of Cotyledons of Tomato Embryo:  Testing the prediction of Self-Organization
Provedor de dados: 17
Autores: Chalapathy  Reddy.
Developmental biologists have long strived to understand how organisms acquire shape and form. The architecture of the mature plant is established during embryogenesis. They have learned much about how gene expression controls the specification of cell type and about how cells interact with one another to coordinate such specific decisions. Far less is known about autocatalytic feedback flow of resource molecules regulating a plant and its parts, shape and form. Indeed, it has even been proposed that the development of shape is not under genetic control but rather is determined by physical forces. Asymmetric development of sinks that depend on common resource pool has been viewed as a consequence of autocatalytic feedback process of flow of resource units...

Asymmetric Intra-household Allocation of Calories in China: Implication for Demographic Bias and the Need for Demographic Targeting
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
This article questions the assumption of symmetric consumption behavior in the conventional analysis of intra-household calorie allocation. It proposes a framework that takes into account asymmetric consumption behavior due to liquidity constraints or loss aversion. Using panel data from China, we find that intra-household calorie allocation responds asymmetrically to expected declines and increases in household food availability, which is qualitatively consistent with the liquidity constraint model. Clarifying such asymmetric responses enables us to relate calorie elasticity estimates to the status of demographic groups within a household without requiring a full interpretation of the ordering of the estimates across demographic groups. Results also show...

Asymmetric Response of Nutrient Intakes to Cereal Price Changes among the Poor in China: Implications for the Effect of Cereal Price Subsidies on the Poor’s Nutrient Intakes
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
Previous studies commonly assume that the effects of introducing and ending cereal price subsidies on the poor’s nutrient intakes are symmetric. We question the assumption of symmetry and show that the poor’s nutrient intakes respond asymmetrically to declines and increases in the price of cereal in China. Our results imply that introducing cereal price subsidies can increase the poor’s total energy intake by increasing their calorie intakes from fat and protein, and that ending such subsidies would insignificantly affect the poor’s total energy intake; however, it may further increase their calorie intakes from fat and protein.

Autores: Verdolini,   Elena; Galeotti,   Marzio.
This paper contributes to the induced innovation literature by extending the analysis of supply and demand determinants of innovation in energy-efficient technologies to account for international knowledge flows and spillovers. In the first part of the paper we select a sample of 38 innovating countries and we study how knowledge related to energy-efficient technologies flows across geographical and technological space. We demonstrate that higher geographical and technological distances are associated with a lower probability of knowledge flow. In the second part of the paper, we use our previous estimates to construct stocks of internal and external knowledge for a panel of 17 countries and present an econometric analysis of the supply and demand...

Athalia longifoliae sp. rev., stat. nov., new for the Netherlands and Germany (Hymenoptera: Tenthredinidae)
Provedor de dados: 16
Autores: Mol, A.W.M.
Athalia longifoliae is removed from synonymy with A. circularis and is upgraded to the species level from A. circularis ssp. longifoliae. The species is recorded for the first time for the Netherlands (19 localities) and for Germany (one locality). Differences between A. longifoliae and A. circularis are described and some notes on the ecology of A. longifoliae are given. In the Netherlands A. longifoliae  was found only in a few limited areas where its host, Veronica longifolia grows, whereas A. circularis is common throughout the Netherlands. As both taxa occur within the same geographical area,  do not interbreed and occupy their own ecological niche, these is no reason to treat A. longifoliae as a subspecies of A. circularis.

Compostos polares foram extraídos da semente de uva desengordurada, em solução contendo acetona, água e ácido acético, resultando em 10,3% de rendimento de extrato de semente de uva desengordurada (ESUD). O ESUD apresentou alta atividade antibacteriana in vitro contra cepas de S. aureus e E. coli, mas não contra cepas de Salmonella sp. A atividade antioxidante do ESUD foi comparável ao ácido ascórbico. A atividade tanante foi considerada baixa para a semente de uva e alta para o ESUD.

Atividade da rubisco e das enzimas de síntese de hidrólise de sacarose, associada à produtividade de látex , em clones de seringueira [ Havea brasiliensis (Willd ex. Adr. de Juss.) Muell.-Arg] cultivados em Lavras, MG
Provedor de dados: 64
Autores: Cairo,Paulo Araquém Ramos; Oliveira,Luiz Edson Mota de; Mesquita,Alessandro Carlos.
Estudos já realizados sobre clones de seringueira cultivados no estado de Minas Gerais têm fornecido indícios que permitem supor a existência de uma possível associação entre a variabilidade fotossintética e a produção de látex. Contudo, ainda é escasso o conhecimento acerca da assimilação de CO2 e o transporte de carbono das folhas até a casca, onde a biossíntese de látex ocorre de forma mais intensa. Em todas as etapas desses metabolismos, as reações são reguladas por algumas enzimas-chave. Este trabalho propôsse a avaliar a atividade da Rubisco e das principais enzimas de síntese e hidrólise de sacarose, em plantas de um jardim clonal de seringueira pertencentes aos clones RRIM 600, GT 1 e FX 2261, e sua relação com o desempenho produtivo de plantas...

Autores: Girón-Pérez,Katherine; Nakano,Octávio; Silva,Amanda C; Oda-Souza,Melissa.
A ocorrência do besouro da cana-de-açúcar, Sphenophorus levis Vaurie, é importante em algumas regiões do Brasil. O dano é causado pelas larvas que perfuram os colmos, ocasionando perdas de até 30 ton /ha/ano. Várias alternativas de controle têm sido utilizadas, embora nenhuma delas com resultados satisfatórios, à exceção do uso de iscas tóxicas. Sendo assim, há necessidade de otimizar sua eficiência ou propor novas técnicas. O objetivo do presente estudo foi avaliar a atratividade dos adultos de S. levis a toletes de cana e casca de abacaxi por meio de olfatômetro em "Y". Os entrenós foram tratados com melaço a 10% e foram testados depois de diferentes tempos de fermentação (24, 48 e 72h), em diferentes horários (diurno e noturno) para ambos os sexos. Os...

Autores: Caetano,Abadio Gonçalves; Ribeiro,Tiago Coelho; Filho,Omar Andrade Rodrigues; Fazan,Valéria Paula Sassoli.
The coronary sinus has lately assumed an important role in the cardiologic clinic once it has been widely used in invasive procedures of the heart. Commonly, it is used during the electrodes implants for the epimiocardic monitoring of the cardiac rhythm, through a biventricular pace maker. These invasive procedures are not possible in hearts with an atresic coronary sinus ostium. In the presence of this anomaly, another may occur: the development of the "Marchal" vein which is a remaining of the left superior vena cava (LSVC). This happens so that the venous blood from the heart can drain into the right atrium, by a communication between the LSVC and the left brachiocephalic vein. The presence of a LSVC brings difficulties when performing an invasive...

RESUMEN Se evaluaron en invernadero en un suelo de Matazul, Meta, Colombia durante 6 semanas, 2 genotipos de Brachiaria (uno mejor adaptado a bajo P, B. decumbens y otro menos adaptado, B. ruziziensis) y 8 progenies del cruzamiento entre ellos ( mejores adaptados: H-7, H-40, H-28, H-58; menos adaptados: H-190, H-94, H-82, H-179). Los genotipos mejor adaptados presentaron mayor biomasa aérea, explicada por mayor área foliar, mayor absorción de P en el tallo y mayor volumen de raíz. Las características morfológicas de las raíces, principalmente longitud, peso seco y contenido de P, permiteron mejor adaptación a bajo P disponible en el suelo. El periodo de evaluación fue suficiente para observar diferencias entre progenies.

Solos desenvolvidos em ambiente de clima semi-árido podem apresentar, naturalmente, acúmulo de sais que comprometem seu uso agrícola, o que pode ser incrementado pelo manejo inadequado da irrigação. Dependendo do uso, a degradação destes solos pode ocorrer com maior ou menor intensidade. Este trabalho teve como objetivo avaliar usos do solo utilizando atributos químicos em um perímetro irrigado na região semiárida do Nordeste do Brasil. Os usos do solo foram separados em áreas com culturas de ciclo curto (C), com fruticultura (F), com pastagem (P), áreas descartadas (D) e áreas com vegetação nativa (V). Coletaram-se amostras de solo deformadas nas camadas de 0-10, 10-30 e 30-60 cm, e indeformadas nas duas primeiras camadas para as determinações químicas e...

Atributos químicos de um latossolo bruno sob sistema plantio direto em função da estratégia de adubação e do método de amostragem de solo
Provedor de dados: 90
Autores: Pauletti,Volnei; Motta,Antonio Carlos Vargas; Serrat,Beatriz Monte; Favaretto,Nerilde; Anjos,Adilson dos.
Adubo em sulco de semeadura nem sempre aumenta a produtividade de culturas anuais, contudo aumenta a variabilidade química das áreas agrícolas, especialmente dos nutrientes P e K. Essa variabilidade é maior no sistema plantio direto por não haver homogeneização da camada superficial pelo preparo mecânico. Neste trabalho, avaliou-se, em um Latossolo Bruno, por longo período sob plantio direto, o efeito de estratégias de aplicação de adubo sobre a distribuição de alguns atributos químicos do solo em profundidade após três e seis anos do início do experimento e sobre a variação desses atributos em função de dois métodos de coleta de amostras de solo, com e sem inclusão da linha de semeadura.

Atributos químicos e físicos de latossolos e sua relação com os rendimentos de milho e feijão irrigados
Provedor de dados: 90
Autores: Amado,Telmo Jorge Carneiro; Pes,Luciano Zucuni; Lemainski,Claudio Luiz; Schenato,Ricardo Bergamo.
Em sistemas de produção agrícola que utilizam a irrigação, uma das principais causas da variabilidade dos rendimentos, a disponibilidade de água para as culturas, é controlada. Nesse caso, outros fatores limitantes ao rendimento, relacionados a atributos de solo, passam a ter sua importância aumentada. Com o objetivo de investigar a variabilidade espacial dos principais atributos químicos e do rendimento de culturas, além de determinar os atributos químicos e físico-hídricos do solo em diferentes zonas de rendimento, foram analisadas duas áreas comerciais irrigadas por pivô central, com 51,8 e 58,2 ha, localizadas, respectivamente, em Trindade do Sul (TS) e Palmeira das Missões (PM), no Rio Grande do Sul (RS). As amostragens para caracterização dos...

Atributos químicos e físicos de um Nitossolo Vermelho Eutrófico léptico argiloso foram avaliados em Passo Fundo (RS) em um experimento sobre o desempenho agronômico de três gramíneas perenes de verão (capim quicuio, capim elefante e capim Tifton 68) para a produção de leite após duas estações de crescimento. O delineamento experimental foi em blocos ao acaso com quatro repetições. Avaliou-se também o solo sob floresta subtropical em área adjacente ao experimento. Os valores de pH, Al, Ca e Mg trocáveis, e P extraível diferiram, em algumas camadas, entre as pastagens estudadas. Algumas pastagens, em relação à floresta nativa favoreceram a elevação do teor de P, em todas as camadas avaliadas. Entre as pastagens, não houve diferença significativa para o teor...

Effects of protein and B-complex vitamin deficiency were assessed with respect to the morphometry of myenteric neurons in the descending colon of adult rats. Sixteen animals were divided into two groups: Control Group (CG, n=8) and Experimental Group (EG, n=8). The CG received 22% protein chow and the EG received 4% protein chow for 120 days. The descending colon was submitted to NADH- and NADPH-diaphorase technique in order to evidence nervous cells in the whole mounts preparations. In the EG, NADH-d positive neurons presented reduced nuclei, while NADPH-d positive neurons showed atrophy of the soma area (~41.7%) inducing an increase of the proportion occupied by the nucleus inside in the soma of these cells.

Provedor de dados: 31
Autores: Springer,   Job D.; Biermacher,   Jon T.; Childs,   M. Dan; Alkire,   Deke O.; Grooms,   Brandon.
A growing number of beef cattle producers in the US are using limited information to determine whether or not it would be economical for them to grow naturally produced cattle.  The objective was to discover the attributes that marketing companies prefer for the naturally produced cattle they purchase, and to elicit the price premiums being offered for cattle that possess these attributes.  Results of a phone survey of companies that purchase natural cattle show that 27 out of 32 companies report their willingness to pay a premium of $5.95/cwt for cattle that have never received antibiotics, ionophores, hormones or animal by-products.

Attributes related to seasonal herbage growth in white clover
Provedor de dados: 63
Autores: Scheneiter,Omar; Rosso,Beatriz; Corletto,Mauro.
When breeding temperate forage species is investigated, some attributes such as herbage accumulation and seasonal growth patterns have to be considered. To modify some of these traits, knowledge of the detailed process might be useful. In order to evaluate seasonal growth of contrasting white clover populations an experiment was carried out. Treatments were five cultivars and three local populations collected in Argentina. Weekly measures were taken during each season to calculate leaf appearance and flower appearance rates, stolon growing rate and dry matter (DM) net accumulation. Different germplasm of this species have different mechanisms for DM accumulation. Leaf size, more than leaf appearance rate, was the variable with most differences among...

Auctioning Greenhouse Gas Emissions Permits in Australia
Provedor de dados: 31
Autores: Betz,   Regina; Seifert,   Stefan; Cramton,   Peter; Kerr,   Suzi.
Allocating permits based on individual historical emissions (‘grandfathering’), or industry benchmark data, is an important design aspect of an emissions trading scheme. Free permit allocation has proven complex and inefficient (particularly in the European Union) with distribution implications also politically difficult to justify. For these reasons, auctioning emissions permits has become more popular than allocating permits.   The European Union is now moving towards auctioning more than 50 per cent of all permits in 2013. In the US, the Regional Greenhouse Gas Initiative (RGGI) has started with auctioning 100 per cent of permits. The Australian proposal for a Carbon Pollution Reduction Scheme (CPRS) also provides for auctioning a significant share of...

Auctioning Monopoly Franchises: Award Criteria and Service Launch Requirements
Provedor de dados: 31
Autores: Dosi,   Cesare; Moretto,   Michele.
We study the competition to acquire the exclusive right to operate an infrastructure service, by comparing two different specifications for the financial proposals - "lowest price to consumers" vs "highest concession fee", and two alternative contractual arrangements: a contract which imposes the obligation to immediately undertake the investment required to operate the concessioned service and a contract which simply assigns to the winning bidder the right to supply the market at a date of her choosing. By comparing the returns of these alternative award criteria and concessioning conditions, we show that concessioning without imposing rollout time limits may or may not provide a higher expected social value, depending on the bidding rule used to allocate...

Organic fruit and wine producers have to use organically produced plant material if  available on the market. To support and enhance this difficult production sector a  project was started in 2003 funded by the Coop Naturaplan Fonds. The improvement  or development of better methods for fertilization, soil management, growth regulation  and plant protection are the main objectives of this project. In our trials with apple  trees we found that an intensification of the nitrogen fertilization including application  of foliar fertilizers did not result in a better quality of young trees. The use of the  bacterial bio-fertilizer BactoFil® Professional-2 without any nitrogen fertilization  increased the tree quality under our conditions. In another experiment...

Shading with nets of 2 m and 3 m width respectively, which reduce the photosynthetic  active radiation by 74%, lead to successful fruit thinning of apple trees. In field trials,  three days of shading reduced fruits per 100 flower clusters to a satisfactory extent for  Golden Delicious (if shading occurred after 19, 26 and 33 days after full bloom  (DAFB)) and Topaz (if shading occurred after 19 and 26 DAFB). For Elstar, seven  days shading at 25 DAFB resulted in a good thinning effect. However, practicability of  the method in commercial orchards has to be improved.

From 2002 to 2006, 7 % of the certified organic farmers in Norway opted out. A  combination of a qualitative and quantitative approach was used to explore how many  farmers consider to opt out, their reasons for this, and how close to or far from the  organic principles they plan to manage the farm afterwards. 24 % of the certified  organic farms consider to opt out in the next 5 to 10 years. The main reasons were  frustration about certification, too low subsidies and premium prices, and unpredictable  political frame conditions. Most plan to change to conventional farming, but  more than 25 % plan to practice close to organic standards, with no or little use of  pesticides and artificial fertilizers.

These programs fell a long way short of achieving their stated goals. It is proposed that to be able to spend their considerable public funds in cost effective ways, they would have needed a number of particular characteristics. Among other things, they needed to prioritise investments well, consistent with an appropriate role of government, and based on analyses that integrated good quality bio-physical and socio-economic information. They needed to select policy mechanisms that would be appropriate for the circumstances. The incentives created by program rules and...

Auswirkungen der Entkopplung der Direktzahlungen auf den  ökologischen Landbau in Deutschland
Provedor de dados: 21
Autores: Offermann, Dr. Frank; Sanders, Dr. Jürn; Nieberg, Dr. Hiltrud.
The 2003 CAP reform has a strong influence on the financial performance of organic  and conventional farming by decoupling direct payments and reducing price support.  This paper aims to identify and assess the impact of the CAP reform on the relative  profitability and production structure of organic farms in Germany. The statistical  analysis of FADN data from the years 2003/04 and 2006/07 suggests that differences  in payments from the first pillar decreased as a result of the reform, affecting positively  the relative profitability of organic farms. A survey among German organic farmers  revealed however that only a minority attributes changes in profits to the CAP reform  and decoupling, respectively. This suggests that organic farmers still require...

Autores: Barth, Dr. Kerstin; Schneider, Regula; Roth, Béatrice; Hillmann, Dr. Edna.
The introduction of mother-bonded calf rearing into organic dairy farming faces some  problems. Regarding the cow, the disturbed milk ejection seems to be the most important  one. We compared two groups of cows, which had permanent (Kp, n=11) or temporarily  (Kt,n=13) contact to their calves until the 90th day p.p. with cows separated  from their offspring within 24 h after calving (Ko, n=24). Since suckling following the  machine milking strongly influences milk ejection, the Kt-cows were allowed to meet  their calves 15 minutes before the usual milking times (milking interval 10:14 hours) in  a separated area. Milk flow curves were recorded at the 6th day after calving and  afterwards every fortnight at least until the 90th day of lactation. At the same...

Auswirkungen der Novellierung des EEG auf die Wettbewerbskraft der Biogasproduktion
Provedor de dados: 31
Autores: Rauh,   Stefan.
Im Zuge des Ausbaus der Biomasseproduktion für energetische Zwecke wurden zuerst insbe-sondere stillgelegte Flächen herangezogen. Doch mittlerweile sind quasi keine freien Flächen mehr verfügbar und besonders regional kommt es zu Konkurrenzen zwischen der Nahrungs-mittel- und der Energieproduktion. Welcher Bereich die notwendigen Agrarrohstoffe für sich beanspruchen darf, entscheidet der Markt. Die Fläche als Ursprung der Agrarrohstoffe ge-winnt demnach an Wert, was die Entwicklung auf dem Pachtmarkt zeigt. Zur Abschätzung welches Produktionsverfahren die höchste Entlohnung dieser knappen Ressource verspricht, dient die Bodenrente, also der Betrag, der nach Abzug aller Kosten noch zur Verfügung steht. Die erneute Novellierung des EEG im Jahr 2008 hat zu...

Auswirkungen eines EU-Agrarfreihandelsabkommens auf den Biolandbau in der Schweiz
Provedor de dados: 21
Autores: Sanders, Jürn.
Das aktuell in der Schweiz diskutierte EU-Agrarfreihandelsabkommen stellt die Schweizer Landwirtschaft vor grosse Herausforderungen. Angesichts der bestehenden Unterschiede in den Produzentenpreisen zwischen der Schweiz und der EU ist davon auszugehen, dass sich als Folge eines solchen Abkommens deutliche Einkommenseinbussen für die Schweizer Landwirtschaft ergeben würden. Vor diesem Hintergrund geht dieser Beitrag der Frage nach, welche Auswirkungen eine solche Liberalisierung auf den Biolandbau in der Schweiz hätte.     Mit Hilfe des Agrarsektormodells FARMIS wurden hierzu verschiedene Liberalisierungsszenarien untersucht, die jeweils unterschiedliche Preis- und Direktzahlungsniveaus unterstellen. Die Ergebnisse der Modellanalyse zeigen auf, dass eine...

It is the aim of the present study with 93 organic fattening pigs of varying Duroc gene portion (0 %, 25 %, 50 %, and 75 %) to deduce the optimal Duroc gene percentage.  Increasing Duroc gene portions resulted in an impaired feed conversion ratio, decreasing lean meat content, and increasing intramuscular fat content. It is concluded that in a carcass quality based marketing system Duroc gene percentage should not exceed 50 %, whereas already 25 % Duroc gene portion significantly promotes meat quality. Only for marketing systems very strictly based on meat quality Duroc gene portion should have 75 % due to a significant promotion of intramuscular fat content.

Auswirkungen von Komposten und von Gärgut auf die  Umwelt, Bodenfruchtbarkeit, sowie die Pflanzengesundheit: Ökologische Bewertung der organischen Substanz
Provedor de dados: 21
Autores: Fuchs, Jacques G.; Schleiss, Konrad.
Bisher war es für Kompost und Gärgut in Ökobilanzen üblich, die Nährstoffe als Substitute von Mineraldüngern und die Schwermetalle als Belastungen einzusetzen. Im Vergleich zur Verbrennung, wo die organische Substanz vollständig mineralisiert und energetisch genutzt wird, gibt es bei Kompost und Gärgut eine Lücke: wie soll die organische Substanz bewertet werden?  Zur Bewertung der organischen Substanz in Ökobilanzen gibt es zwei grundlegend verschiedene Vorgehensweisen:  1. Einsetzen der einzelnen Effekte wie Erosionsreduktion, weniger Zugkraftbedarf, bessere Wasserhaltekapazität, weniger Krankheitsanfälligkeit etc. mit jeweils entsprechenden LCA-Modulen  2. Globales Einsetzen von Substituten, welche die Effekte möglichst gut abbilden.   Gegen die erste...

Authentication of Organic Milk Using δ13C and the  alpha-Linolenic Acid Content of Milk Fat
Provedor de dados: 21
Autores: Molkentin, Joachim.
The carbon stable isotope ratio (δ13C) and the alpha-linolenic acid (C18:3ω3) content of milk fat were analyzed to examine their applicability as general markers for the authentication of organic retail milk in Germany. To record the variable effect of feeding, including the seasonal influence on milk composition, three conventionally and three organically produced brands of retail milk were collected biweekly during a period of 18 months. Altogether 286 milk samples were analyzed. Threshold values for the identification of German organic milk were established and allowed to delimit almost all conventional samples. Organic retail milk was always above a minimum C18:3ω3 content of 0.50% and below a maximum δ13C of -26.5‰. The universal and strongly negative...

Consumer demand for healthy, safe and high quality food is increasing. Against this  background, the demand for organically grown food has been growing rapidly. Organic  farming contains the whole food chain from field to fork. An analyse system to optimise  the process needs to be established (QualityAnalysisCriticalControlPoint). The aim  of the transnational CORE-Organic QACCP project is a chain analysis which addresses  the link between farm and fork and backwards from fork to farm. The objective is  to improve product related quality management in farming and processing. The results  presented here are dealing with food authenticity on farm level through biocrystallization  measurements and food safety through pesticide residue and nitrate...

Autoimmune diseases in the TH17 era
Provedor de dados: 56
Autores: Mesquita Jr.,D.; Cruvinel,W.M.; Câmara,N.O.S.; Kállas,E.G.; Andrade,L.E.C.
A new subtype of CD4+ T lymphocytes characterized by the production of interleukin 17, i.e., TH17 cells, has been recently described. This novel T cell subset is distinct from type 1 and type 2 T helper cells. The major feature of this subpopulation is to generate significant amounts of pro-inflammatory cytokines, therefore appearing to be critically involved in protection against infection caused by extracellular microorganisms, and in the pathogenesis of autoimmune diseases and allergy. The dynamic balance among subsets of T cells is important for the modulation of several steps of the immune response. Disturbances in this balance may cause a shift from normal immunologic physiology to the development of immune-mediated disorders. In autoimmune diseases,...

The objective of this study is to provide the first report of bone marrow transplantation (BMT) in dogs in Brazil. A Rottweiler with cutaneous lymphoma was submitted to a twelve-week Madison-Wisconsin chemotherapy protocol followed by autologous bone marrow transplantation. For this, 10mL kg-1 of bone marrow was collected simultaneously from both iliac crests and cryopreserved in a freezer at -80°C. The conditioning step was performed by administering cyclophosphamide by intravenous route at 400mg m-2. Bone marrow was reinfused after defrosting in a water bath at 37°C. Bone marrow nucleated cell counts before and after freezing, showed a small relative loss of nucleated cells (35.10 and 31.80x10³µL-1 , respectively). Cyclophosphamide induced neutropenia...

Most of the fish stocks are assessed using age-based models, however age estimations using otoliths costs several million euros annually. In this context, Automatic Fish Ageing (EU Project) would provide means to standardize ageing among laboratories and build interpreted image databases ensuring the information conservation. Automation improves growth studies while reducing the cost of the acquisition of age data. The whole processing chain from the acquisition of otolith data to the actual ageing issue using pattern recognition or statistical inference has been realised for three case studies : a) Cod (Gadus morhua ; Faeroes, North Sea, North East Arctic) b) Anchovy (Engraulis encrasicolus ; Bay of Biscay) c) Plaice (Pleuronectes platessa, Eastern...

Autores: The HAPMAP Team; The PROSITE Team; Edouard de Castro; Alan Bridge; UniProt Consortium.
The development of next generation sequencing technologies promises a massive increase in the rate of submission of new protein sequences to sequence databases such as the Universal Protein Resource Knowledge Base, UniProtKB. At UniProtKB/Swiss-Prot we propose to meet this challenge by continuing to expand and develop systems for the automatic propagation of existing annotation to newly submitted protein sequences. These developments will promote the standardization of ortholog annotation both across and within kingdoms and significantly enhance our ability to accurately annotate new protein sequences which are being produced at an ever increasing rate.&amp;#xd;&amp;#xa;

Autores: van den Heuvel, Saskia; Vermeer, Loes.
Het gelijktijdig beweiden van geiten is een situatie waar Skal naar toe wil werken. Met Groene Geit is afgesproken dat er een overgangstermijn is tot 2013. Meerdere productiegroepen is het grootste knelpunt bij gelijktijdig beweiden. De voornaamste reden waarom gebruik wordt gemaakt van productiegroepen is het rantsoen. Daarom wordt momenteel door veel biologische ondernemers gekozen voor flat feeding. Naast flat feeding is automatisering een mogelijkheid om het aantal productiegroepen te verminderen. Dit rapport is geschreven om te inventariseren of automatisering een bijdrage kan leveren om geiten gelijktijdig te beweiden.

Available potential energy diagnosis in a direct numerical simulation of rotating stratified turbulence
Provedor de dados: 5
Autores: Roullet, Guillaume; Klein, Patrice.
Review of three studies devoted to the available potential energy (APE) leads to the proposal of a diagnosis for APE, well-suited for rotating stratified flows within the primitive equations (PE) framework in which anharmonic effects (due to large vertical displacements of isopycnals) are permitted. The chosen diagnosis is based on the APE definition of Holliday &amp; McIntyre (J. Fluid Mech., vol. 107, 1981, pp. 221-225) and uses the background stratification of Winters et al. (J. Fluid Mech., vol. 289, 1995, pp. 115-128). Subsequent evaluation of the APE in a PE direct simulation (1/100 degrees, 200 levels) of oceanic mesoscale turbulence indicates that anharmonic effects are significant. These effects are due to large vertical displacements of the...

Avaliação com Doppler colorido e espectral da veia porta de cães
Provedor de dados: 65
Autores: Sartor,Raquel; Mamprim,Maria Jaqueline.
A perfusão total do fígado e suas contribuições relativas, pelo sistema portal e pela artéria hepática, podem estar alteradas por vários processos hepáticos, como doença hepato-celular difusa, neoplasia e shunts intra-hepáticos. O estudo do comportamento do fluxo sangüíneo nos vasos do fígado por meio da ultra-sonografia Doppler tem demonstrado que este é um método viável não-invasivo e de grande auxílio, principalmente na avaliação da hemodinâmica portal. São duas as modalidades de ultra-sonografia Doppler com maior aplicação na rotina para avaliação de fluxo nos vasos abdominais, o Doppler espectral e o Doppler colorido. Na doença hepática crônica, ocorre alteração da complacência hepática devido à fibrose ou à cirrose, as quais acarretam alterações...

Avaliação comparativa das perdas de água por evapotranspiração em mesocosmos colonizados por diferentes macrófitas aquáticas
Provedor de dados: 87
Autores: Rosa,C.S.; Antunes,R.D.; Pitelli,R.A.; Pitelli,R.L.C.M.
Uma das mais importantes formas de interferência das macrófitas aquáticas em corpos hídricos é o aumento das perdas d'água para a atmosfera pela evapotranspiração. Em alguns corpos hídricos esse aumento pode ser considerado uma interferência negativa e indesejável, especialmente em reservatórios para armazenamento de água e reservatórios de acúmulo para geração de energia elétrica. Assim, este trabalho foi realizado com o objetivo de comparar as perdas d'água em mesocosmos colonizados com macrófitas aquáticas importantes em corpos hídricos no Brasil, mais especificamente Myriophyllum aquaticum, Brachiaria subquadripara, Echinochloa polystachya, Typha latifolia e Pontederia lanceolata. As avaliações foram conduzidas no mês de julho de 2004, em três períodos...

Autores: Lange,Marcela Kist; Heberlé,Graziela; Milão,Denise.
Vários são os fatores que podem ocasionar a instabilidade de uma emulsão, destacando-se a oxidação, reação prevenida pelo emprego de antioxidantes. O butil-hidróxi-tolueno (BHT) tem sido um dos antioxidantes sintéticos mais utilizados em formulações cosméticas, porém, a busca da indústria farmacêutica e cosmética pelo emprego de produtos de origem natural tem sido cada vez maior. Visto isso, o objetivo do presente trabalho foi a incorporação do resveratrol, um composto fenólico encontrado principalmente em uvas bem como em vinhos tintos, em uma emulsão base não-iônica para avaliação do perfil de estabilidade e atividade antioxidante em comparação a uma emulsão base não-iônica contendo o BHT. O perfil de estabilidade foi analisado pela observação das...

Avaliação da incidência de Grapholita molesta (Lepidoptera: Tortricidae) em burrknots de macieira.
Provedor de dados: 14
Autores: SANTOS, R. S. S. dos; VIEIRA, C.
A exploração econômica da maçã tem sofrido prejuízos devido ao ataque de inúmeros insetos, entre os quais o da mariposa oriental Grapholita molesta (Busck, 1916) (Lepidoptera: Tortricidae). Este inseto tem ocorrência em quase todos os países e, possivelmente, seu centro de origem seja a Ásia (Salles, 1984). Ao longo dos anos a mariposa oriental se tomou uma das mais importantes pragas da fruticultura temperada do sul do Brasil, principalmente sobre espécies de rosáceas, como o pessegueiro (Botton et aI., 2001); ameixeira (Hickel et aI., 2003) e macieira (Kovaleski e Ribeiro, 2002), entre outras. Kovaleski e Ribeiro (2002) apontam que as perdas ocasionadas por este inseto, em macieira, vêm aumentando nas últimas safras, chegando a 5% em algumas situações....

Autores: Botega,Juliana V. L.; Braga Júnior,Roberto A.; Machado,Maurício P. P.; Lima,Luiz A.; Faria,Rafael O.
Algumas das características especiais do laser associadas a fenômenos ópticos, permitem uma série de aplicações na área biológica, baseadas no fenômeno conhecido como "biospeckle". A técnica do biospeckle tem sido desenvolvida como uma ferramenta para análise da atividade de materiais biológicos, monitoramento de umidade, nível de atividade e presença de parasitos, dentre outros atributos. Apesar do monitoramento ocorrer através da iluminação do material por uma fonte de laser de baixa potência, a influência da luz na atividade biológica do espécime passa a ser sempre uma variável a ser investigada. Com este trabalho se objetivou avaliar a influência do laser na análise da atividade biológica medida pelo biospeckle de um tecido vegetal, caso em que uma...

Avaliação da predação de Podocnemis expansa e Podocnemis unifilis (Testudines, Podocnemididae) no rio Javaés, Tocantins
Provedor de dados: 36
Autores: Salera Junior,Giovanni; Malvasio,Adriana; Portelinha,Thiago Costa Gonçalves.
Podocnemis expansa e P. unifilis são animais de vida longa, com uma demorada maturação sexual, o que influencia uma baixa taxa de substituição de indivíduos. Suas populações são caracterizadas por uma pequena mortalidade dos animais adultos, mas alta taxa de mortalidade de filhotes e embriões. Sendo a predação natural de ninhos e filhotes um dos fatores mais importantes do baixo sucesso de eclosão dessas espécies. No rio Javaés, os ovos e recém-eclodidos podem ser predados por uma grande diversidade de animais: dentre as aves, urubus (Coragyps atratus e Cathartes aura), carcará (Polyborus plancus), jaburu (Jabiru mycteria); lagartos (Tupinambis teguixin) e mamíferos de pequeno porte, coati (Nasua nasua) e cachorro-do-mato (Cerdocyon thous).

A microbiota é um fator de grande importância na qualidade e conservação de vegetais minimamente processados. Muitos microrganismos podem afetar adversamente a qualidade e a segurança desses produtos, considerando que microrganismos patogênicos, que normalmente não estariam presentes, passam a compor a microbiota contaminante decorrente do manuseio a que são submetidos. Objetivou-se, neste trabalho, determinar a qualidade microbiológica de hortaliças, anterior e posteriormente ao processo de sanitização, como também o período final da vida-de-prateleira dos produtos sanitizados, avaliando-se a presença de Listeria sp., Listeria monocytogenes e Salmonella sp.

Provedor de dados: 70
Autores: Assis,Renato L. de; Lazarini,Gilmar D.; Lanças,Kléber P.; Cargnelutti Filho,Alberto.
Com os crescimentos da população e da demanda por alimentos, novas tecnologias têm surgido visando ao aumento da produtividade e à redução nos custos de produção. Se por um lado essas tecnologias elevam a produção e reduzem os custos, por outro o tráfego intenso de máquinas e tratores alteram a estrutura do solo, tornando-o compactado, comprometendo, assim, a produtividade agrícola. Neste trabalho, relacionou-se o teor de água do solo com a sua resistência à penetração, para quatro tipos de solo e quatro condições de umidade, utilizando penetrômetro hidráulico-eletrônico com sistema de navegação DGPS. Os resultados mostraram que ocorreram modificações nas condições de atrito entre o cone e o solo com o aumento do teor de água, facilitando a penetração da...

Autores: BRANDAO, E. S.; COSTA, J. R. P. F. da; ZARONI, M. J.; LAFORET, M. R. C.
O zoneamento da área de risco climático do sorgo no Estado de Pernambuco veio atender a uma demanda do setor avícola que estava crescendo mas seus custos eram altos pela dependência do milho para a produção da ração das aves. O milho é muito sensível à estiagem enquanto o sorgo é cultivado em áreas muito secas e/ou muito quentes próprias da região do Semi-árido e Sertão, onde a produtividade de outros cereais é antieconômica. Este trabalho fez uma avaliação dos impactos da tecnologia do zoneamento do risco climático da cultura do sorgo nas áreas do semi-árido de Pernambuco, sob os aspectos econômicos, sociais e ambientais. O estudo abrangeu um período de três anos, empregando a Metodologia de Referência da Embrapa. Sob o ponto de vista econômico, o...

Avaliação da utilização de Nim (Azadirachta indica) para o controle parasitário em bovinos de produção leiteira em sistema orgânico.
Provedor de dados: 21
Autores: Silva, Claudia Bezerra da; Brito, Guilherme Rodrigues; Sanavria, Argemiro; Soares, João Paulo Guimarães.
As infestações parasitárias são responsáveis por sérios prejuízos econômicos na pecuária leiteira por causarem danos para a saúde animal. O controle de ectoparasitos com produtos químicos convencionais tem sido realizado de forma indiscriminada, ocasionando o desenvolvimento acelerado de resistência aos princípios ativos, contaminação do ambiente e dos produtos de origem animal, provocando preocupação na sociedade e órgãos governamentais. Desta forma, o uso de métodos alternativos, como o de plantas de potencial fitoterápico (ação repelente e larvicida) surge como um tratamento simples e de baixo custo, resultando no resgate da medicina popular, principalmente para atender o sistema orgânico de produção leiteira. Tais substâncias naturais são consideradas...

Autores: CORDEIRO, A. C. C.; RANGEL, P. H. N.; MEDEIROS, R. D. de.
É provável que a reduzida base genética das populações utilizadas nos programas de melhoramento de arroz no Brasil represente um dos fatores que contribuem para o estabelecimento de patamares de produtividade. Uma das opções para aumentar a variabilidade genética é a utilização de espécies silvestres que ocorrem no Brasil, como é o caso da O. glumaepatula que é entre as espécies conhecidas, a mais promissora para uso em hibridações interespecíficas, por ser autógama, diplóide e possuir genoma semelhante ao da espécie cultivada. O objetivo deste trabalho foi avaliar genótipos oriundos de hibridação interespecífica entre O. sativa x O. glumaepatula, nas condições de Roraima, visando indicar as de melhor performance para participar na formação de novas...

Autores: Monteiro,Adriano L. N.; Montenegro,Abelardo A. de A.; Montenegro,Suzana M. G.; Santos,Francisco X. dos.
Este trabalho foi realizado em um vale aluvial irrigado do semiárido do Brasil (Estado de Pernambuco). O objetivo foi investigar o efeito de lâminas de lixiviação e de precipitação no controle da salinidade do solo em lisímetros de drenagem. Com base em simulações numéricas, utilizando-se do modelo HYDRUS-1D, avaliaram-se o fluxo e o transporte de sais na zona não saturada. Mediante medidas de campo de evapotranspiração real e precipitação, foi possível inferir que o modelo se apresentou como ferramenta adequada nas simulações realizadas, para diferentes cenários de lâminas de lixiviação. Verificou-se, experimental e numericamente, que a lixiviação parcial pode ser utilizada como alternativa de manejo para a redução da salinidade na zona radicular, desde...

Avaliação de linhagens de arroz irrigado em Roraima com tipo de grão para a culinária japonesa.
Provedor de dados: 14
Autores: CORDEIRO, A. C. C.; RANGEL, P. H. N.; MEDEIROS, R. D. de.
Em Roraima, o cultivo do arroz representa uma das poucas cadeias produtivas efetivamente estabilizadas, com produção suficiente para abastecer o mercado interno e permitir exportação para outros Estados. No entanto, as agroindústrias locais que comercializam, basicamente, o arroz branco de classe longo-fino, podem ter na diversificação de tipos de grãos, como os demandados para a culinária japonesa, uma oportunidade de verticalização da produção e aumento de renda, já que o preço desse produto chega a ser,em média, duas a três vezes superior ao tipo local. Assim, o objetivo deste trabalho foi avaliar o desempenho produtivo de linhagens de arroz irrigado com tipo de grãos para a culinária japonesa, nas condições de cultivo de Roraima. Foram avaliadas,no...

AVALIAÇÃO DE METODOLOGIAS DE REGIONALIZAÇÃO DE VAZÕES MÍNIMAS DE REFERÊNCIA PARA BACIA DO RIO SÃO FRANCISCO
Provedor de dados: 107
Autores: Demétrius David da Silva; UFV; Felipe de Azevedo Marques; Alysson Feliciano Lemos.
No presente estudo foram avaliadas três metodologias de regionalização de vazões mínimas de referência (Q7,10, Q90 e Q95) aplicadas à bacia hidrográfica do rio São Francisco a montante do reservatório de Três Marias, sendo estas: a) Eletrobrás (1985), que utiliza equações de regressão regionais; b) Chaves et al. (2002), que utiliza técnicas de interpolação e extrapolação; e c) vazão específica. Os valores das vazões mínimas de referência estimados pelas três metodologias foram comparados com os valores observados em cada uma das 28 estações fluviométricas usadas na regionalização. O método que apresentou maior precisão foi o proposto pela Eletrobrás (1985), resultando em três equações de regionalização de vazões, com erro relativo médio de 26,8 %. Entre as...

Avaliação de seleções mutantes de figueira cv. Roxo-de-Valinhos
Provedor de dados: 94
Autores: Rodrigues,Maria Gabriela Fontanetti; Correa,Luiz de Souza; Boliani,Aparecida Conceição.
A figueira (Ficus carica L.), pertencente à família das Moráceas, constitui-se numa das mais importantes frutíferas cultivadas, elevando o Brasil à condição de décimo maior produtor e exportador de figos do mundo. Porém, a ficicultura apresenta alguns problemas fitossanitários, além de, no Brasil, estar toda implantada com uma única cultivar, a Roxo-de-Valinhos, que produz frutos sem sementes, inviabilizando o melhoramento convencional. Nesse sentido, o melhoramento genético, com o uso de mutagênicos, passa a ser uma linha de pesquisa altamente importante, podendo contribuir enormemente para o desenvolvimento da cultura. Diante disto, o objetivo do presente trabalho foi avaliar seleções mutantes de figueira originadas de plantas formadas por estacas...

Avaliação de vidro reciclado granulado como meio filtrante de herbicidas em meio aquoso
Provedor de dados: 91
Autores: Assis,Odilio B. G.; Vieira,Delia do C.
Neste trabalho resultados e considerações sobre o uso de vidro reciclado na forma de material granulado, como potencial meio filtrante para remoção de agrotóxicos diluídos em água são apresentados. Para esta avaliação garrafas e vasilhames de vidro transparente foram fragmentados e moídos até partículas com tamanhos inferiores a 1 mm e ensaios de filtração gravitacional realizados em colunas, em escala laboratorial. O herbicida atrazina foi escolhido como contaminante em virtude de ser um composto altamente tóxico e amplamente empregado no Brasil. Análises por cromatografia gasosa indicam a retenção de agrotóxicos pelo meio poroso, em todo o intervalo de concentrações avaliadas (0,5; 1,0; 3,0; 10 e 15 mg L-1). O vidro apresentou-se como material de fácil...

Autores: Lima,Antonio Luís dos Santos; Lima,Keila dos Santos Cople; Coelho,Maysa Joppert; Silva,Jaqueline Michele; Godoy,Ronoel Luiz de Oliveira; Pacheco,Sidney.
Buriti do Brejo (Mauritia flexuosa L.) é um típico fruto da Amazônia, Nordeste e Centro-Oeste brasileiro, muito utilizado na culinária para produção de sucos, doces e vinhos. É considerado uma excelente fonte de carotenóides precursores da vitamina A, apresentando maior concentração de β-caroteno. Além dos carotenóides também encontramos ácido ascórbico e açúcares. O ácido ascórbico administrado em quantidades suficientes pode prevenir os sinais clínicos de deficiência conhecida como escorbuto. O emprego da radiação ionizante gama tem mostrado um potencial efeito na redução de perdas pós-colheita, mantendo a qualidade nutricional dos alimentos. O presente trabalho teve como objetivo avaliar os efeitos da radiação gama, nas doses de 0,5 kGy e 1,0 kGy, na...

Provedor de dados: 123
Autores: Fragoso,Rui; Marques,Carlos.
Este artigo avalia os efeitos de políticas de tarifas da água no uso agrícola, em termos do consumo de água, do aproveitamento das áreas beneficiadas com regadio, do rendimento do produtor agrícola, da recuperação dos custos com a água e do desenvolvimento agrícola. A metodologia utilizada baseia-se na elaboração de um modelo de programação matemática multiperíodo, adaptado às características específicas de uma empresa agrícola do Sul de Portugal. Foram analisadas a tarifa fixa por área beneficiada, a tarifa volumétrica por metro cúbico de água consumida, a tarifa binómica e a tarifa progressiva. Para as simulações, foram considerados um cenário produtivo tradicional e um cenário produtivo alternativo, em que são introduzidas culturas de valor acrescentado.

O objetivo do presente trabalho foi avaliar se a seleção para conversão alimentar (CA) e ganho de peso (GP), com base no desempenho individual e ou coletivo dos láparos, pode produzir ganhos genéticos em progênies criadas coletivamente, e animais submetidos à avaliação no período de 50 a 70 dias de idade, utilizando inferência Bayesiana. Realizaram-se seis análises bicaráter. No teste de desempenho foi observado que as características ganho de peso e conversão alimentar em ambos os ambientes tiveram valores para herdabilidade que variam de 0,42 a 0,60. Tanto a correlação genética 0,44 a 0,68 (GP) e 0,23 a 0,56 (CA) como a fenotípica 0,30 (GP) e 0,17 (CA) foram positivas para a mesma característica quando avaliada nos dois ambientes, coletivo ou individual,...

Autores: Pieniz,Simone; Colpo,Elisângela; Oliveira,Viviani Ruffo de; Estefanel,Valduíno; Andreazza,Robson.
O efeito protetor exercido por frutas e hortaliças tem sido atribuído à presença de compostos antioxidantes. Objetivou-se, neste estudo, avaliar in vitro a capacidade antioxidante de um grupo de frutas e hortaliças, cruas e cozidas, através da diminuição da peroxidação lipídica, induzida por ferro em fígado de ratos. Foram utilizados fígados de ratos homogeneizados, que foram submetidos à oxidação pelo ferro. As frutas e hortaliças foram utilizadas como antioxidantes, a fim de combater o estresse oxidativo induzido pelo ferro. O método utilizado neste trabalho foi a Reação ao Ácido Tiobarbitúrico (TBARS), tendo como marcador para avaliar o estresse oxidativo o Malonaldeído (MDA). De acordo com os resultados obtidos, observou-se que houve uma diminuição...

Três experimentos foram conduzidos com o objetivo de avaliar o efeito da adição de complexo enzimático (CE) sobre o valor nutritivo da casca de soja utilizada na alimentação de suínos na fase inicial. O complexo enzimático utilizado continha α-galactosidase, β-glucanase, galactomananase e xilanase. No experimento 1, determinou-se a digestibilidade da casca de soja com complexo enzimático (0, 200 e 300 mg/kg) em leitões com peso inicial de 22,49 ± 1,73 kg. Nenhum dos níveis de complexo enzimático afetou a digestibilidade da casca de soja. Assim, realizou-se outro ensaio de digestibilidade (experimento 2) com dois níveis (0 e 600 mg/kg) de complexo enzimático e, novamente, a adição de complexo enzimático (600 mg de CE/kg de ração) não melhorou a...

Autores: Oliveira,Flávia Camargo de; Albuquerque,Ulysses Paulino de; Fonseca-Kruel,Viviane Stern da; Hanazaki,Natalia.
A Etnobotânica moderna é produto de mudanças históricas ocorridas dentro e fora da academia. O trabalho buscou traçar a trajetória dessa disciplina e suas tendências no Brasil. Para tal foi realizado um levantamento dos trabalhos, no período de 1968-2007, desenvolvidos por pesquisadores brasileiros no país e publicados nas revistas científicas de circulação nacional, internacional e em eventos nacionais. O artigo discute sobre o desenvolvimento da Etnobotânica e sobre a crescente valorização do conhecimento construído por populações não-industrializadas. Neste contexto destaca-se a influência das mudanças de interesses científicos e econômicos ao longo dos períodos avaliados e, especialmente, da implementação da Convenção sobre Diversidade Biológica.

Autores: Magda Assem; Thorraya Abedel- ALhameid; Gihan A-Basset; Amany M. Hilal; Mahmoud Kamel; Iman Khalil; Nahla Alsharkawey; Ayman Metwally.
Background: Several anti apoptotic signals have been recently identified. Aven and Survivin are broadly expressed and are conserved in mammalian species. Patients and Methods: 39 AML and 25 ALL were tested. Aven and Survivin expression were detected by RT-PCR. DNA fragmentation was carried out daily after treatment..Results: Survivin was expressed (P=0.06) more in AML (74%) than in ALL (52%). While, Aven was equally expressed in both leukemias. Patients were categorized into 3 groups based on DNA fragmentation. Absence of Aven significantly (p&amp;#x2039;0.001) contributed to DNA fragmentation,but Survivin did not contribute as much. None of the concordant both positive Survivin and Aven were in group III (the good 5 day fragmentation, (P&amp;#x3c; 0.001)....

Averaging Transformations of Synaptic Potentials on Networks
Provedor de dados: 17
Autores: Hamid Reza Noori.
The problem of the transformation of microscopic information to the macroscopic level is an intriguing challenge in computational neuroscience, but also of general mathematical importance. Here, a phenomenological mathematical model is introduced that simulates the internal information processing of brain compartments. Synaptic potentials are integrated over small number of realistically coupled neurons to obtain macroscopic quantities. The striatal complex, an important part of the basal ganglia circuit in the brain for regulating motor activity, has been investigated as an example for the validation of the model.

É apresentada uma revisão histórica dos inventários ornitológicos conduzidos na Chapada dos Guimarães, centro-oeste do Brasil. A avifauna da região é caracterizada a partir de uma revisão crítica de todas as listas de espécies produzidas por várias gerações de ornitólogos, espécimes depositados em museus e meticulosos trabalhos de campo. Especial atenção foi dada às publicações de J.A. Allen, baseadas na monumental coleção preparada por H.H. Smith e sua esposa no final do século XIX. A avifauna da região é típica do Cerrado, abrigando também espécies amazônicas. Um total de 393 espécies de aves é listado para a região, sendo outras 52 espécies citadas pela literatura consideradas de ocorrência improvável baseado nos critérios restritivos adotados. Vinte e...

Aves da fazenda Nhumirim e seus arredores: lista 2008.
Provedor de dados: 14
Autores: NUNES, A. P.; TIZIANEL, F. A. T.; TOMAS, W. M.; LUPINETTI, C.
A avifauna da fazenda Nhumirim e arredores representam a diversidade de aves na planície do Pantanal, pois aproximadamente 54% do total das espécies pantaneiras ocorrem na região. Esta elevada diversidade de aves é um reflexo da heterogeneidade de ambientes na paisagem regional que, salvo algumas áreas vizinhas, ainda mantém os padrões ecológicos típicos do Pantanal da Nhecolândia. Foram acrescidas 31 espécies na nova listagem de aves da fazenda Nhumirim e seus arredores. Ressalta-se, no entanto, que novos registros de aves são esperados para a região, uma vez que o Pantanal da Nhecolândia é uma das principais rotas de aves migratórias de várias espécies setentrionais e austrais no Centro Oeste do Brasil.

Avian blood parasites in the National Natural Park Chingaza: high Andes of Colombia
Provedor de dados: 68
Autores: Rodríguez,Oscar A.; Moya,Helena; Matta,Nubia E.
Birds from the high Andes in the National Natural Park Chingaza, Colombia, were surveyed for blood parasites in April 2002 and March 2003. Of 136 birds examined, representing 40 species of 14 families, 38 were infected with blood parasites. Parasites of the genera Leucocytozoon (21.3% prevalence), Plasmodium (8.1%), Hepatozoon (2.9%), Microfilariae (2.9%) and Haemoproteus (1.5%) were recorded. Twenty five avian species in this survey were examined for blood parasites for the first time and 49 new parasite-host associations were identified. The most striking observation of this study was the high prevalence of Leucocytozoon spp. In the Neotropics, the prevalence of Leucocytozoon spp. has not been reported to be greater than 0.2% and is closely associated...

Autores: Sipos,   Nikoletta.
A közúti közlekedés káros hatásának csökkentése érdekében Magyarországon is bevezethető lenne az ún. „biciklipénz”, melyet a biciklivel, illetve gyalog munkába járó dolgozók adómentes juttatásként kapnának. Pozitív externális hatás a környezetszennyezés elkerülésén túl, az egészségi állapot javulásán keresztül a TB-kiadások csökkenése, a közlekedés ezen módja hely- és energiatakarékos is. A városi útdíj bevezetésével az önkormányzatok bevételi forrása nőne, a versenyképesség, a település élhetősége, környezete és közlekedése javulna. A gépjármű-biztosításra kivetett biztosítási adóval belföldön tarthatóvá válna az országban keletkezett jövedelem, valamint a gépjárműbalesetek miatt jelentkező egészségügyi költségeket (a munkába járás esetén is) a TB helyett...

Megállapítható, hogy a tanácskozáson résztvevők véleménye a fundamentális kérdésekben közel esik egymáshoz, bár vannak még különbségek, főleg a javasolt megoldásokban. Ez – az elmúlt két évtizedet figyelembe véve – mindenképpen haladásnak tekinthető. Elmondható, hogy a komoly gondok és problémák összefogásra serkentik a közösségeket. Mindenki érzi, hogy a jelentős agrártradíciókkal rendelke¬ző hazai élelmiszer-gazdaság a jelenlegi pályán maradva alapanyag-termelő agrár¬bérmunkás országgá válhat, elvesztve versenyképességének maradékát is, teljesen kiszolgáltatva, míg az ágazat jövedelemtermelése – jó esetben is – csak a túlélésre elegendő.

Az eredetmegjelölés koncepcionális kérdései a Balatoni Borrégióban
Provedor de dados: 31
Autores: Brazsil,   David; Sidlovits,   Diana.
A magyar szőlő-bor ágazat fejlődését alapvetően befolyásolja a Közösségi Borpiaci Reform kapcsán megváltozó új jogi szabályozás, mely három új, egységes borkategóriát vezet be az Európai Unióban. A Balatoni Borrégió termelési szerkezetéből megállapítható, hogy borainak 99%-a földrajzi árujelzőkkel kerül forgalomba. Ezen árujelzők jövőbeli használatához termékleírás elkészítése kötelező. A termékleírás elkészítése felveti a jelenleg használt földrajzi árujelzők régiós elvek szerinti újragondolását. A „Balatoni” kategóriát oltalom alatt álló földrajzi jelzős termékkategóriává alakítva biztosítható lenne a – termelők nagy részének nagyfokú önállósága melletti – régiós borkategória. Erre építve a jelenlegi m.t. minőségi és védett eredetű kategóriákat, szigorú...

Autores: Beresne,   Martha Bernadett.
A globális pénzügyi és a kibontakozó gazdasági válság időszakában a munkanélküliség jelenti a legsúlyosabb társadalmi és szociális problémát az Európai Unióban és hazánkban is. A tanulmány az országos adatok és folyamatok tükrében az Észak-alföldi Régió munkanélküliséggel kapcsolatos problémáit tárja fel, különös tekintettel az agrárfoglalkoztatás helyzetére. A kutatás egyik legfontosabb következtetése, hogy minél nagyobb a munkanélküliség az adott térségben, annál nagyobb a munkanélküliek között a mezőgazdasági tevékenységgel foglalkozók aránya, azaz a mezőgazdaság szociális ellátó funkciója ezen körzetekben különösen fontos szerepet játszik. A másik fontos megállapítás, hogy a mezőgazdasági munkanélküliség mérséklése érdekében az eddiginél jóval nagyobb...

Az EU-s támogatások és a tagállamok közigazgatásának kapcsolata

Az Európai Unió regionális politikájának intézményi háttere jogszabályokban került lefektetésre. Az intézményrendszer felállítása és működtetése az EU-tárgyalásoknak is kiemelt témája volt. A megkövetelt végrehajtási rendszer minden tagállamban – akár régi, akár újonnan csatlakozott – a meglévő közigazgatási rendszerre épült. Ugyanakkor nem lényegtelen, hogy míg az ún. régi tagállamok, és ezért maga az EU-szabályozás is már az elmúlt 25-35 évben a „New Public Management” eszméjében élt és fejlődött, addig az újonnan csatlakozók még az ezredfordulón is inkább egy bürokratikus közigazgatást működtettek, és kevésbé volt jelen a szolgáltatói szemlélet, illetve eredményorientáció. Annak ellenére, hogy az új tagállamok jelentős időnyomásra állították fel...

Jelen tanulmány elsődleges célja egy szekunder kutatás eredményeinek bemutatása, melyben összefoglalásra került, hogy milyen jellemzőkkel rendelkezik egy információs korszakbeli, az intellektuális tőkére koncentráló teljesítményértékelő metódus. Elmondható, hogy alapvető elvárás egy ilyen módszertől, hogy a múlt információi mellett képes legyen a jelen és a jövő lehetőségeit is számba venni, és a pénzügyi nézőpont mellett további perspektívákat is megjeleníteni. A tanulmány másik fontosabb célja annak a kérdéskörnek a felvázolása, melyben a környezet mint tőkeelem vonásai és értékelésének tulajdonságai vizsgálhatók az intellektuális tőkével párhuzamosan. A cél teljesítésekor kérdések merültek fel, melyek megválaszolása további kutatást igényel. Azonban...

Az ökológiai gazdálkodás hatékonysági kérdései
Provedor de dados: 31
Autores: Alvincz,   Jozsef; Koltai,   Judit Petra.
Az életszínvonal emelkedésével egyre nagyobb hangsúlyt kap az egészséges táplálkozás, és ugyanakkor a mezőgazdasági termelésben jelentkező árutöbbletek kitörési pontok keresésére ösztönzik a gazdálkodókat, így az ökológiai gazdálkodás a mezőgazdaságban tevékenykedők egy csoportjának teljes, illetve részbeni megélhetési alapul szolgálhat. 2005-től azonban jelentős visszaesés tapasztalható mind az ökológiai termelésbe vont terület nagyságát, mind az ökológiai gazdaságok számát tekintve, a gazdálkodók egy része ugyanis különféle más integrált programokba kapcsoló¬dott a kedvezőbb feltételek és a magasabb támogatási összegek miatt.  Az egyes gazdaságtípusok esetében a birtokméret tekintetében szignifikáns különbség alapvetően nem állapítható meg. Mindez...

Az őszi árpa klimatikus igényei és az éghajlatváltozás

Autores: Novak,   Aliz; Erdelyi,   Eva.
Munkánkban összehasonlító vizsgálatokat végeztünk az őszi árpa fejlődési szakasza¬inak klimatikus igényeiről. A becsült meteorológiai jellemzők átlagosan nem mutatnak nagy változást a közeljövőre – jóllehet a század végére már igen –, de eloszlásuk alakulása a mezőgazdaságban komoly következményekkel járhat. A növény szempontjából azonban az éves és havi átlaghőmérséklet, illetve csapadékösszegek elemzése helyett sokkal több információhoz juthatunk, ha a növény fejlődési szakaszait külön-külön vizsgáljuk. Végigkövetve a növény fejlődési szakaszait megállapítható, hogy az őszi árpa klimatikus igényei várhatóan a jövőben is teljesülnek, jóllehet a termésbiztonság ezzel együtt romlani fog.    ----------------------------------------    This paper covers...

Autores: Erdelyi,   Eva; Novak,   Aliz; Ladanyi,   Marta.
Az éghajlatváltozás folyamata már elkezdődött, ezért a magyar agrárkutatóknak és szakembereknek is jól működő leíró-előrejelző rendszereket szükséges alkotniuk. Munkánk célja a hozamok elemzése, az időbeni változások megfigyelése volt 1951-től napjainkig. Az árpa termésmennyiségi adatait a trendhatások kiszűrésével összehasonlíthatóvá tettük. A vizsgálat helyszíne Hajdú-Bihar megye volt. Az ún. E,V hatásossági kritérium alapján vizsgáltuk az árpa terméskockázatának alakulását az 1951-90-es időszakban, továbbá azóta. A kimutatott terméskockázat-növekedés azt a nézetet támasztja alá, hogy az éghajlat „láthatóan” változik, aminek jeleivel szinte naponta találkozunk. Megfigyelt meteorológiai változókból olyan indikátorokat ké¬pezhetünk, amelyek vélhetően...

Azufre, nitratos, nutrición de cultivos forrajeros y fertilidad de un suelo salido-sódico
Provedor de dados: 32
Autores: López Blancas, Sergio.
En la recuperación de suelos salino-sódicos con aplicación de S y establecimiento de cultivos tolerantes, los nitratos pueden lixiviarse en el perfil del suelo o acumularse en el tejido vegetal. Esto podría reducirse mediante la promoción de la oxidación del S aplicado, ya que con ello se favorece la desnitrificación y la absorción de sulfatos por los cultivos, limitando la acumulación de nitratos en el suelo y en las plantas, respectivamente. El objetivo del presente trabajo fue determinar el efecto del S en: la lixiviación de nitratos en el perfil del suelo, la concentración de S, nitratos y micronutrimentos del tejido vegetal, la fertilidad del suelo y el rendimiento de especies forrajeras en un suelo salino-sódico. Se establecieron parcelas con...

B-1 cell: the precursor of a novel mononuclear phagocyte with immuno-regulatory properties
Provedor de dados: 42
Autores: Lopes,José Daniel; Mariano,Mario.
Characterization of the origin, properties, functions and fate of cells is a fundamental task for the understanding of physiological and pathological phenomena. Despite the bulk of knowledge concerning the diverse characteristics of mammalian cells, some of them, such as B-1 cells, are still poorly understood. Here we report the results obtained in our laboratory on these cells in the last 10 years. After showing that B-1 cells could be cultured and amplified in vitro, a series of experiments were performed with these cells. They showed that B1 cells reside mostly in the peritoneal and pleural cavities, migrate to distant inflammatory foci, coalesce to form giant cells and participate in granuloma formation, both in vitro and in vivo. They are also able to...

B6 deficient feeding or homocysteic acid induces the earlier Alzheimer&amp;#x27;s pathological change in normal C57BL male mice
Provedor de dados: 17
Autores: Tohru Hasegawa; Nobuyuki Mikoda; Masashi Kitazawa; Frank LaFerla.
It is the first report that the earlier Alzheimer&amp;#x27;s pathological changes can be induced in normal C57BL mice, by B6 deficient feeding for 3 month, and this pathological changes were completely inhibited by anti-homocysteic acid antibody. According to Koch&amp;#x27;s postulate, if a pathogen of Alzheimer&amp;#x27;s disease is administrated to the normal animal, we would observe the Alzheimer&amp;#x27;s pathology in the normal animal. We actually have observed this pathology in normal C57BL male mice.

Baby Boom Migration and Its Impact on Rural America
Provedor de dados: 31
Autores: Cromartie,   John; Nelson,   Peter.
Members of the baby boom cohort, now 45-63 years old, are approaching a period in their lives when moves to rural and small-town destinations increase. An analysis of age-specific, net migration during the 1990s reveals extensive shifts in migration patterns as Americans move through different life-cycle stages. Assuming similar age patterns of migration, this report identifies the types of nonmetropolitan counties that are likely to experience the greatest surge in baby boom migration during 2000-20 and projects the likely impact on the size and distribution of retirement-age populations in destination counties. The analysis finds a significant increase in the propensity to migrate to nonmetro counties as people reach their fifties and sixties and...

Back to the future: investigating historical data of bluefin tuna fisheries
Provedor de dados: 5
Autores: Fromentin, Jean-marc.
The exploitation of Atlantic bluefin tuna in the Mediterranean Sea goes back to the first millennium before Christ and the Romans already took benefits of the bluefin tuna reproductive migration to catch them. Bluefin tuna catch did not remain stable along its millennium exploitation history but displayed conspicuous long-term fluctuations that could result from environmentally-driven changes in the bluefin tuna migration routes. The Nordic fisheries that took place in the Norwegian and North Sea in the early 1920s were the most spectacular example of Atlantic bluefin tuna fisheries collapse. During the 1950s, the Nordic fisheries were the most productive ones, catching up to 18,000 tons/year, but they suddenly crashed down without any warning in 1963....

Backqualität von Winterweizen in Bio- und Extenso Prüfungen
Provedor de dados: 21
Autores: Kleijer, Dr. G.
Winter wheat trials have been carried out from 2002 to 2007 under extensive or organic  conditions. The results of baking quality analyses have been compared for the  same varieties, cultivated under both conditions during the same year. Rheological  analyses generally show lower results for the varieties cultivated under organic conditions  when baking tests result nearly identical in both networks. Wet gluten is an  important baking quality parameter for the users. The percentage of wet gluten is not  correlated with the gluten index, the extensographe energy or the points obtained by  the baking tests. This parameter alone cannot be used for determination of the baking  quality.

Bacteria diversity and microbial biomass in forest, pasture and fallow soils in the southwestern Amazon basin
Provedor de dados: 90
Autores: Cenciani,Karina; Lambais,Marcio Rodrigues; Cerri,Carlos Clemente; Azevedo,Lucas Carvalho Basílio de; Feigl,Brigitte Josefine.
It is well-known that Amazon tropical forest soils contain high microbial biodiversity. However, anthropogenic actions of slash and burn, mainly for pasture establishment, induce profound changes in the well-balanced biogeochemical cycles. After a few years the grass yield usually declines, the pasture is abandoned and is transformed into a secondary vegetation called "capoeira" or fallow. The aim of this study was to examine how the clearing of Amazon rainforest for pasture affects: (1) the diversity of the Bacteria domain evaluated by Polymerase Chain Reaction and Denaturing Gradient Gel Electrophoresis (PCR-DGGE), (2) microbial biomass and some soil chemical properties (pH, moisture, P, K, Ca, Mg, Al, H + Al, and BS), and (3) the influence of...

Brazil has a unique position in the world. It is one of the few countries that can be one of the most important producers of food, fiber and biofuel and at the same time maintain its mega biodiversity endowment and vital ecosystems services properly running. This is a challenge that only can be achieved by recognizing the importance of agribusiness sector to the Brazilian economy, but also that ecosystems have limits and we should not endless expand agriculture in the name of "development". Ecosystem services have to be recognized also as a "development" to be kept for the next generations. Agriculture only exists where ecosystems are able to maintain its basic functioning. Therefore, a well preserved nature it is the most precious asset of agriculture.

Este último sector presentó en promedio una densidad de 70.000 sem m-2 contra 36.720 sem m-2 en el primero. La representación de semillas de especies nativas se redujo notablemente en el ambiente agrícola. Stipa caudata con 31360 sem m-2 resultó la especie más abundante en el pastizal. En el ambiente de cultivo, su densidad se redujo a 9940 sem m-2 y...

O melhoramento genético do cafeeiro por meio de métodos convencionais é um processo demorado para se obter uma nova cultivar. A redução desse tempo é possível através da produção de linhagens homozigóticas, oriundas de dihaplóides obtidas através da cultura de anteras. Objetivou-se aplicar a técnica da cultura de anteras em diferentes cvs. de Coffea arabica L. para induzir a formação de calos e regenerar plântulas di-haplóides, com uso de reguladores vegetais. Os experimentos foram conduzidos no laboratório de Biotecnologia Vegetal da Universidade Federal de Uberlândia (UFU).

Barcoding lepidoptera: current situation and perspectives on the usefulness of a contentious technique
Provedor de dados: 82
Autores: Silva-Brandão,Karina L; Lyra,Mariana L; Freitas,André V L.
Faced by a growing need of identification and delimitation of new and established cryptic species that are being lost at an increasing rate, taxonomists can now more than ever take advantage of an enormous variety of new molecular and computational tools. At this moment they should be open to all new available technologies in the so called "technology-driven revolution" in systematics. The use of the "DNA barcode" has been discussed by those applying successfully this approach to identify and diagnose species and by those who believe that the flaws in the use of this molecular marker are as many as to negate the worth of its employment. For insects of the order Lepidoptera neither side seems totally correct orwrong, and although many groups of...

Barium extraction potential by mustard, sunflower and castor bean
Provedor de dados: 63
Autores: Coscione,Aline Renée; Berton,Ronaldo Severiano.
Barium salts are used extensively for industrial purposes, generating residues that, if not appropriately disposed, can increase soil Ba content. The aim of the present work was to evaluate Ba extraction potential of mustard (Brassica juncea Czern.), sunflower (Helianthus annuus L.), and castor bean (Ricinus communis L.), grown in a soil artificially contaminated with increasing Ba additions. A greenhouse experiment was carried out by adding BaSO4 to a Rhodic Hapludox sample, at the 0, 150 and 300 mg kg-1 rates. After harvesting, the pot soil material was also analyzed for exchangeable Ba by CaCl2 extraction and by an ion exchange resin method. None of the plant species tested presented toxicity symptoms, decreased nutrient accumulation or decreased dry...

Barraginhas: água de chuva para todos.
Provedor de dados: 14
Autores: BARROS, L. C. de; RIBEIRO, P. E. de A.
Nas últimas quatro décadas, com o desmatamento acelerado em nosso País, foram introduzidas lavouras e pastagens, sem os devidos cuidados de conservação de solo e sem a preocupação com reposição de nutrientes.Essas pastagens introduzidas cresceram vigorosas, o que motivou os produtores a adotarem maior densidade de gado por área, acelerando a compactação dos solos, a qual reduziu as taxas de infiltração da água das chuvas, provocando escorrimento superficial em forma de enxurrada. Assim, terra e nutrientes foram arrastados pela erosão (laminar e sulcada), um processo que acelerou a degradação do solo e afetou a sustentabilidade agrícola. Para reverter esse quadro, a Embrapa Milho e Sorgo, sediada no Município de Sete Lagoas, em Minas Gerais, desenvolveu o...

Barriopsis iraniana and Phaeobotryon cupressi: two new species of the Botryosphaeriaceae from trees in Iran
Provedor de dados: 16
Autores: Abdollahzadeh, J.; Mohammadi Goltapeh, E.; Javadi, A.; Shams-bakhsh, M.; Zare, R.; Phillips:, A.J.L.
Species in the Botryosphaeriaceae are well known as pathogens and saprobes of woody hosts, but little is known about the species that occur in Iran. In a recent survey of this family in Iran two fungi with diplodia-like anamorphs were isolated from various tree hosts. These two fungi were fully characterised in terms of morphology of the anamorphs in culture, and sequences of the ITS1/ITS2 regions of the ribosomal DNA operon and partial sequences of the translation elongation factor 1-α. Phylogenetic analyses placed them within a clade consisting of Barriopsis and Phaeobotryon species, but they were clearly distinct from known species in these genera. Therefore, they are described here as two new species, namely Barriopsis iraniana on Citrus, Mangifera and...

Qualquer programa de melhoramento genético de uma espécie vegetal pode ser dividido em etapas, tais como, seleção de genitores, cruzamentos, desenvolvimento e avaliação das linhagens, ensaios de rendimento e recomendação. As fases de seleção de genitores, avaliação de linhagens e ensaios de rendimento são aquelas em que a estatística pode desempenhar um papel importante como um instrumental de auxílio ao melhorista na tomada de decisão. O número de tratamentos (linhagens ou cultivares), a disponibilidade de sementes e o grau de precisão requerido naquela etapa são os fatores mais importantes na definição dos delineamentos e dos testes estatísticos a serem empregados, quando necessários.

Basis Volatilities of Corn and Soybean in Spatially Separated Markets: The Effect of Ethanol Demand
Provedor de dados: 31
Autores: Bekkerman,   Anton; Pelletier,   Denis.
The 2006 spike in corn-based ethanol demand has contributed to the increase in basis volatility in corn and soybean markets across the United States, which has, to a significant degree, led to the observed large jumps in the prices of the two commodities. Despite the overall rise in basis volatility, there remain differences in the degree of volatility that exists across spatially separated markets, which might be caused by factors such as transportation costs, seasonality, and time-to-delivery. The focus of this study is threefold first, this work models basis data for six corn and soybean markets by using a multivariate GARCH model that incorporates the spatial linkages of these markets; next, the model is used to investigate whether the increase in...

Beginning Farmers and Ranchers
Provedor de dados: 31
Autores: Ahearn,   Mary Clare; Newton,   Doris J.
USDA defines beginning farmers and ranchers as those who have operated a farm or ranch for 10 years or less either as a sole operator or with others who have operated a farm or ranch for 10 years or less. Beginning farmers tend to be younger than established farmers and to operate smaller farms or ranches, some of which may provide no annual production. Beginning farmers often face obstacles getting started, including high startup costs and limited availability of land. USDA—through the Farm Service Agency and the Natural Resources Conservation Service—provides loans and conservation assistance to beginning farmers and ranchers. This report draws on data from annual surveys and the Census of Agriculture to provide policymakers with a better understanding...

Pelagic and demersal guilds of piscivorous fishes are linked by a variety of biological and physical processes that mediate interactions with common prey species. Understanding the behaviors of predators and prey can provide insight into the conditions that make such linkages possible. Here we report on the behaviors of mid-water piscivorous fishes and the responses of prey that produce feeding opportunities for demersal piscivorous fishes associated with "live bottom" ledge habitats off the coast of Georgia (northwest Atlantic Ocean). Prey taxa reduced nearest neighbor distances and retreated towards the seafloor during predatory attacks by mid-water fishes. Demersal fishes subsequently attacked and consumed prey in these ephemeral high density patches....

Behavior of tamarins, tanagers and manakins foraging in a strangler fig (Ficus sp.) in Suriname, South America: implications for seed dispersal
Provedor de dados: 49
Autores: Vanderhoff,Elizabeth Natasha; Grafton,Brian.
The behavior of foragers can directly affect the dispersal of seeds. Strangler figs are keystone resources throughout the tropics and are important resources for both primates and birds. We examined the foraging behavior of golden-handed tamarins and four bird species in a strangler fig to see how these behaviors might affect the dispersal of fig seeds. Tamarins removed fruit at a faster rate than did any of the bird species examined. Additionally, tamarins tended to swallow figs whole whereas birds tended to drop figs once they were processed. Tamarins visiting fig trees ingest large quantities of fig seeds that may be deposited throughout the forest. Birds on the other hand tended to slowly process fruits near the fig tree and drop processed fruit...

Behavior of the vegetable crops section in three types of food retail stores in Campo Grande, Brazil
Provedor de dados: 75
Autores: Lima-Filho,Dario de O; Hokama,Anderson S; Spanhol,Caroline P.
The behavior of the fresh fruits and vegetable produce section was evaluated, under the point of view of the consumer, in three types of food retail stores in Campo Grande, Brazilian southeast: a grocery store ("quitanda"), a supermarket, and an open-air market. A quantitative-descriptive survey was conducted with 120 individuals, responsible for purchasing fresh fruit and vegetable produce for their homes. To accomplish that, twelve variables were investigated and adapted from the parameters used in the SERVQUAL model, in which the attributes of the retail outlet are pointed out, such as store hygiene and cleanliness and manner by which produce is displayed; employee training traits, such as courtesy and helpfulness; and quality, price range, and variety...

Behavior patterns of rural government in product structure adjustment of planting industry - A of Case Cangshan County in Shandong Province, China
Provedor de dados: 31
Autores: Gao,   Ren; Xing,   Angang.
This paper introduces the three behavior relationship patterns between rural government and peasant household in the product structure adjustment of planting industry in China. Based on the investigation on the government behavior in product structure adjustment of Cangshan County of China, we summarize and evaluate the 5 representative types of rural government behavior. Analysis results show that the optimization of rural government behavior pattern in China is beneficial to the optimization of household behavior and the product structure of planting industry. Finally, we put forward related countermeasures for optimizing the rural government behavior.

Behavioral experiments in a wild passerine cause short-term reductions in parental provisioning and nestling mass
Provedor de dados: 97
Autores: VAN DONGEN,WOUTER F.D; LAZZONI,ILENIA; VÁSQUEZ,RODRIGO A.
Research on wild animals often involves the capture and temporary removal of individuals from their territory. Although the acute effects of such procedures are well understood in terms of stress hormone profiles, their effect on the behaviour of captured individuals after release is poorly known. Additionally, for socially-monogamous individuals captured whilst breeding, little is known regarding whether the remaining individual compensates for the temporary loss of its partner and whether offspring condition or survival ultimately decreases due to any reductions in parental provisioning. We investigated the influence of field-based experiments requiring temporary adult removal on adult provisioning behaviour and nestling mass in the thorn-tailed rayadito...

Behavioral repertory of Trichodactylus panoplus (Crustacea: Trichodactylidae) under laboratory conditions
Provedor de dados: 103
Autores: Zimmermann,Bianca L.; Aued,Anaide W.; Machado,Stela; Manfio,Daiara; Scarton,Laura P.; Santos,Sandro.
This work describes the behavioral repertory of Trichodactylus panoplus von Martens, 1869, based on the animals' diel activity and the possible substrate preference under laboratory experiments. Three experimental replicates were carried out, each using six animals (three males and three females). There were four periods of observation a day, with a total of 864 observation sessions and 144 hours of experiments. A total of 15 behavioral acts divided into five categories were recorded: feeding, exploration of the environment, immobility, social interaction, and self-grooming. The obtained results suggest that T. panoplus has greater activity during the night (p &lt; 0.05), yet without showing an activity peak. In addition, the acceptance of food does not...

Due to etching effects on broad leafed weeds, fine ground kainite was used for weed  control before synthetic herbicides have become common practice in conventional  farming. According to the organic standards kainite can be used as potassium  fertiliser. The present study investigates optimal growing stages for application in  organic winter wheat and the range of effectiveness. Kainite was applied at a rate of  800 kg per hectare alternatively at EC 29 and EC 30 under the conditions of morning  dew on days with high sunshine duration. At both growing stages kainite application  reduced the population of hairy vetch, chamomile, cornflower, field pansy, winter rape,  common chickweed and persian speedwell. Application at early growing stages led to  a...

Das Forschungsprojekt „Bekämpfung der Blutlaus (Eriosoma lanigerum Hausm.) in ökologischen Obstanlagen durch Etablierung von Ohrwürmern (Forficula auricularia L.) und Bewertung unterstützender Bekämpfungsverfahren“ lief in Zusammenarbeit verschiedener Forschungs- und Beratungseinrichtungen von April 2007 bis Dezember 2009. Ziel des Projektes war es, auf Basis von Versuchsergebnissen eine betriebliche Behandlungsstrategie zur Bekämpfung der Blutlaus durch den gezielten Ohrwurmeinsatz und Ölbehandlungen zu entwickeln.  Der Einfluss der Ohrwürmer erwies sich als schwer nachweisbar. Dies kann mehrere Gründe haben. Zum einen verteilen sich die Ohrwürmer über die Anlage, so dass ein Effekt in den einzelnen Varianten dadurch ausgeglichen wird, dass die Ohrwürmer...

Fusarium graminearum (FG) is the most prevalent Fusarium Head Blight (FHB)  fungus in Switzerland. In conventional agriculture, fungicides are used to reduce the  risk of FHB infection and mycotoxin contamination of wheat. As an alternative for  organic wheat production, we examined plant-based products that showed antifungal  effects from our previous late blight field trials. In bioassays, the effect of these  antifungal plant preparations (APP) was screened against FG. In 2006 and 2008, the  most active APP, Rheum palmatum, Frangula alnus and preparations of Galla  chinensis as well as a plant substance (PSX), were used as FHB control agents in  field trials with artificial FG infections. In both years, FG incidence and deoxynivalenol  content were...

Snow mold, caused by the fungal pathogen Microdochium nivale, is an important  seed-borne disease of various cereals and fodder plants, leading to reduced stands  after emergence. No agricultural measures are known to prevent snow mold, hence,  direct control measures are needed. For organic agriculture, seed dressing with plantbased  products could be an alternative. In contrast to spray treatments onto the crop,  the formulation and application of plant preparations onto seeds represents a greater  challenge in terms of adhesion, persistence, and lasting efficacy. In the current study,  three plant-based powders applied with two different seed coating materials were  tested for their efficacy against MN of wheat. Both adjuvants demonstrated equally...

Below Cost Legislation – Did it matter and would it really matter today?
Provedor de dados: 31
Autores: Collins,   Alan Michael.
This paper traces the emergence, evolution, and demise of below cost legislation in the grocery industry in Ireland. The paper explores retail buyers’ views of the Grocery Order (1987) and the effect, if any, it had on grocery buyer behaviour, competition among retailers, and vertical competition along the food chain until it was repealed in 2006. It addresses the matter of buyers’ likely response to the Order, had it remained in effect, in the current depressed market environment. Views of independent retailers are also provided on the Order. The paper finds that grocery buyer behaviour was determined by the buoyant consumer market and that the Groceries Order acted to depress competitive forces and direct supplier-buyer negotiations to off-invoice...

Mudanças no conceito de visão do mundo das pessoas estão mudando devido à limitação dos recursos naturais, questões de origem ética sobre o bem-estar de animais, emergência e re-emergência de enfermidades e qualidade dos alimentos. A sociedade começou a se interessar mais em saber como seu alimento é produzido e exigir produtos que sejam ?limpos, verdes e éticos?, em que se preconiza o uso de práticas que minimizem ou evitem completamente tratamentos químicos ou hormonais nos animais e preservem, dessa forma, a saúde humana. Bem-estar é um termo amplo que inclui uma somatória de elementos que contribuem para a qualidade de vida do animal, levando-o a um bom estado de harmonia com o seu ambiente, caracterizado por condições físicas e fisiológicas adequadas....

Since 2004, the Queensland Department of Primary Industries and Fisheries has embarked on a rigorous evaluation of its R&amp;D Programs, with Benefit Cost Analysis being a cornerstone of this work. The analyses conducted to date have proved to be powerful tools in internal resource re-allocation. However, the process used has been time consuming, partly because there needs to be adequate time allowed for consultation both with scientists and with senior staff. Experience has highlighted the need for strong organisational support to the analysts carrying out the work.

Benefits from ecological study methods to taxonomy of enchytraeids in southern Mata Atlântica
Provedor de dados: 86
Autores: Schmelz,Rüdiger Maria; Peña,Rut Maria Collado de la; Römbke,Jörg.
The objective of this work was to determine how taxonomy benefited from the ecological quantitative and site-based sampling methods in enchytraeids studies. Enchytraeids (small relatives of earthworms) were sampled in different phases of rain forest regeneration in the southern Mata Atlântica in Paraná, Brazil. The research combined ecological and taxonomic work, because enchytraeids are poorly studied and difficult to identify, and many new species were expected. The provision of large numbers of specimens enabled the test of species diagnoses by investigating the ranges of character variations in a larger series of specimens. Simplified species diagnoses adapted to the local conditions that allowed the identification of all specimens, juveniles included,...

Benefits of Improved Groundnut Technologies to Resource-poor Farmers: A Participatory Approach
Provedor de dados: 31
Autores: Govindaraj,   G.; Kumar,   G.D. Satish; Basu,   M.S.
Considering that non-adoption of improved groundnut technologies by the small and resource-poor farmers is due to non-availability of quality seeds, poor knowledge, inappropriateness of technologies, etc., in the current study, improved groundnut technologies have been implemented through participatory mode so as to generate awareness about improved technologies among them. The participatory approach could make the farmers to learn, adopt and spread new technologies. The economic indicators have shown that a net return of Rs 7104 per ha was realized by adopting improved varieties and integrated crop management (ICM) package during kharif season, and it is higher than the returns realized by growing local variety (AK-12-24) with local practice (Rs 2010/ha)....

Benefits of Organic Agriculture as a Climate Change Adaptation and Mitigation Strategy in Developing Countries
Provedor de dados: 21
Autores: Müller, Adrian.
Organic agriculture, as an adaptation strategy to climate change and variability, is a concrete and  promising option for rural communities and has additional potential as a mitigation strategy. This article  is a short review of this topic. Adaptation and mitigation based on organic agriculture can build on wellestablished  practice because organic agriculture is a sustainable livelihood strategy with decades of use in  several climate zones and under a wide range of specific local conditions. The financial requirements of  organic agriculture as an adaptation or mitigation strategy are low. Further research is needed on yields in  organic agriculture and its mitigation and sequestration potential. Other critical points are information  provision and...

BENTAZON-MCPA EFFECT ON Fusarium oxysporum ROOT ROT ON Trifolium pratense IN GREENHOUSE CONDITIONS
Provedor de dados: 127
Autores: Ceballos,Ricardo; Cofre,Ximena; Quiroz,Andrés; Espinoza,Nelson; Palma,Graciela.
In Chile, the main factor in red clover {Trifolium pretense L.) stand decline is fusarium-root rot, which results in a reduction in yield. Fusarium oxysporum (Schlect.) is the most prevalent pathogen recovered from diseased red clover roots plants. Agronomical management of red clover includes application of broadleaf herbicides such as MCPA and bentazon. This study was conducted to evaluate the effects of bentazon and bentazon/MCPA mixture on phytotoxicity and root rot as caused by F. oxysporum on red clover, under greenhouse conditions. In addition, in vitro mycelial growth and conidial germination of F. oxysporum was studied. A reduction of 40% in crown diameter and 57% shoot dry weight was observed 30 days after treatment with a high rate of...

Best Management Practices: How Economical is it in Southern Agricultural Systems?
Provedor de dados: 31
Autores: Matekole,   Augustus N.; Westra,   John V.; Appelboom,   Timothy W.
Conventional drainage systems tend to aggravate runoff and nutrient leaching problems on farms especially during the off-season. This study uses a biophysical economic model to identify, evaluate and determine multifunctional benefits of implementing and establishing nitrogen rate fertilizer application and conservation tillage practices as best management practices (BMPs) in the lower Mississippi River Basin (MRB). Simulation results showed that agricultural producers generally preferred no tillage to conventional tillage in reducing nutrient runoffs from fields because of higher net revenue per acre. Finally, given nitrogen runoff restrictions, farmers reduced crop acreage and nitrogen fertilizer application rates to help minimize losses.

Best Management Practices to Enhance Water Quality: Who is Adopting Them?
Provedor de dados: 31
Autores: Ghazalian,   Pascal L.; Larue,   Bruno; West,   Gale E.
This study investigates the determinants affecting producers’ adoption of some Best Management Practices (BMPs). Priors about the signs of certain variables are explicitly accounted for by testing for inequality restrictions through importance sampling. Education, gender, age, and on-farm residence are found to have significant effects on the adoption of some BMPs. Farms with larger animal production are more apt to implement manure management practices, crop rotation, and riparian buffer strips. Also, farms with larger cultivated acres are more inclined to implement herbicide control practices, crop rotation, and riparian buffer strips. Belonging to an agro-environment club has a positive impact for most BMPs.

Bestimmung der Determinanten der Rapspreisentwicklung in der Hochpreisphase auf Basis von Markovzeitreihenmodellen

Autores: Busse,   Stefan; Brümmer,   Bernhard.
Der Einfluss der Entwicklungen auf verschiedenen Agrarmärkten auf den deutschen Rapsmarkt wird im vorliegenden Beitrag anhand von multivariaten Zeitreihenmodellen für die Produktpreise untersucht. Da sich in Hochpreisphasen die Preisanpassungsprozesse möglicherweise im Vergleich zu Phasen niedriger Preise ändern, wird auf ein nichtlineares Vektor-Fehlerkorrektur-Modell (VFKM) zurückgegriffen, das regimeabhängige Anpassungen zulässt. Die Spezifikation des Modells als Markovsprung-VFKM (MS-VFKM) erweist sich hier als vorteilhaft, da es keiner a priori Regimespezifizierung und -abgrenzung bedarf. Die Analyse zeigt, dass in den Jahren 2007/08 signifikante Änderungen in den Anpassungsprozessen der Rapspreise im Verhältnis zu anderen Agrargütern auftraten, wobei...

In organic farming the cultivation of leguminous crops is one of the most important  sources of nitrogen (N). However, regarding the amount of N fixed, there are hardly  any published data for winter peas. Therefore, the N fixation of five regular leafed  winter peas types and one semi-leafless spring pea cultivar in single and mixed  cropping (with winter rye spring cereals respectively) was measured in four successive  growing seasons (2003/04 – 2006/07) at the experimental farm of the University of  Kassel and in two consecutive vegetation periods (2005/06 - 2006/07) at the  experimental farm of the University of Applied Science in Osnabrueck.

Food quality has become an important topic in the food market. Thus, suppliers have  started offering conventional products including additional quality attributes, such as  “free from GMO” or “free from additives”. We analysed the preferences and buying  behaviour regarding such conventional “low-input” products in competition with conventional  and organic product alternatives in consumer choice experiments in Germany  and Switzerland. In the experiments, we tested milk, yogurt and apples. The choice  experiments were combined with face-to-face interviews in order to collect information  about the participating consumers, which might explain the buying behaviour observed  in the choice experiment.

Autores: Vormann, M.; von Borstel, U.; Leisen, E.
In order to produce high quality forages, the species composition of the grass sward is of special importance. A good measure for estimating the quality of grass swards is  the so-called mean Futterwertzahl of the sward by Klapp (1965) which is further referred to as Sward Quality Index (SQI). On 56 organic farms the average SQI of the farm has been calculated and the yield proportion of different species of the sward has been calculated for different regions of Northwest Germany. Within 22 organic farms  with grassland farming exclusively, a comparison of the milk yields (kg ECM/cow and year) and the mean SQI of the grassland has been calculated with special regard to  the concentrate rates fed to the cows. In tendency the results show lower SQI in farms...

In 1995, Daniel Pauly identified a "shifting baselines syndrome" (SBS). Pauly was concerned that scientists measure ecosystem change against their personal recollections of the past and, based on this decidedly short-term view, mismanage fish stocks because they tolerate gradual and incremental elimination of species and set inappropriate recovery goals. As a concept, SBS is simple to grasp and its logic is compelling. Much current work in marine historical ecology is rationalized in part as a means of combating SBS, and the term has also resonated outside of the academy with environmental advocacy groups. Although we recognize both conceptual and operational merit in SBS, we believe that the ultimate impact of SBS on ocean management will be limited by...

Beyond Darwin: On the role of niche construction and self-organization in evolution
Provedor de dados: 97
Autores: MARQUET,PABLO A.
In this essay I point out to two processes that can potentially complement the classical view of evolution by natural selection as outlined by Darwin, which captures only part of the processes driving adaptive evolution. This classical view should be complemented with sources of order generated within the biological system itself in response to its own structure and dynamics (i.e. self-organization) and by considering the existence of a fundamental circularity in the interaction between the organism and its environment, such that the action of the organisms modify their selective environment thereby affecting their own evolution. The formalization and inclusión of these two processes (and their interaction) represent major challenges and opportunities for...

Among the strategies to promote sustainable tropical forest development around the world, the Federal Extractive Reserve System of Brazil is widely cited as an exemplary model. It is designed to protect rubber tapper communities, their forests, and their livelihoods while preventing deforestation and conserving biodiversity. In response to changing markets and policies, rubber tappers in the Chico Mendes Extractive Reserve have recently diversified production to include market agriculture and cattle production, precipitating deforestation in the reserve, with the implication of increased ecological degradation compared to the extraction of nontimber forest products (NTFPs). Our remote sensing and forest inventory analyses yield different insights about the...

Computational models are becoming more and more the central scientific paradigm for understanding the complexity of living systems. With the increasing number and size of these models there is a growing need for model reuse and exchange. Furthermore, detailed models are not manageable without computer support. There are efforts to formalise the mathematical structure of models (e.g. SBML) and to standardise the kinetic and biological meaning of model components (e.g. SBO, GO, UniProt). However, formalising only the structure of computational models is not sufficient to easily exchange and reuse models and to achieve full computer support for modelling. We also need to formalise the pragmatical and dynamical aspects of...

Autores: Behrens,   Kristian; Lamorgese,   Andrea R.; Ottaviano,   Gianmarco I.P.; Tabuchi,   Takatoshi.
The standard two-country model of international trade with monopolistic competition predicts a more-than-proportional relationship between a country’s share of world production of a good and its share of world demand for that same good, a result known as the “home market effect”. We first show that this prediction does not generally carry through to the multi-country case, as production patterns are crucially affected by third country effects. We then derive an alternative prediction that holds whatever the number of countries considered. This new prediction takes into account important features of the real world such as comparative advantage due to cross-country technological differences and lack of factor price equalization.

By many estimates, the world has just crossed the point where more than half the world’s population is urban, a trend driven by rapid urbanization in developing countries. Urban centers offer economies of scale in terms of productive enterprise and public investment. Cities are social melting pots, centers of innovation and drivers of social change. However, cities are also marked by social differentiation, poverty, conflict and environmental degradation. These are all issues that not only matter to cities but also lie at the heart of development. As such the time is right to consider afresh the relationship between cities and development. This paper introduces a significant new collection of multidisciplinary papers focused on urbanization and its...

Bias in culture-independent assessments of microbial biodiversity in the global ocean
Provedor de dados: 17
Autores: Ben B. Temperton; Anna Oliver; Dawn Field; Bela Tiwari; Martin Muhling; Ian Joint; Jack Gilbert.
On the basis of 16S rRNA gene sequencing, the SAR11 clade of marine bacteria has almost universal distribution, being detected as abundant sequences in all marine provinces. Yet SAR11 sequences are rarely detected in fosmid libraries, suggesting that the widespread abundance may be an artefact of PCR cloning and that SAR 11 has a relatively low abundance. Here the relative abundance of SAR11 is explored in both a fosmid library and a metagenomic sequence data set from the same biological community taken from fjord surface water from Bergen, Norway. Pyrosequenced data and 16S clone data confirmed an 11-15% relative abundance of SAR11 within the community. In contrast not a single SAR11 fosmid was identified in a pooled shotgun sequenced data set of 100...

Bias in the prediction of genetic gain due to mass and half-sib selection in random mating populations
Provedor de dados: 74
Autores: Viana,José Marcelo Soriano; Faria,Vinícius Ribeiro; Silva,Admilson da Costa e.
The prediction of gains from selection allows the comparison of breeding methods and selection strategies, although these estimates may be biased. The objective of this study was to investigate the extent of such bias in predicting genetic gain. For this, we simulated 10 cycles of a hypothetical breeding program that involved seven traits, three population classes, three experimental conditions and two breeding methods (mass and half-sib selection). Each combination of trait, population, heritability, method and cycle was repeated 10 times. The predicted gains were biased, even when the genetic parameters were estimated without error. Gain from selection in both genders is twice the gain from selection in a single gender only in the absence of dominance....

Biased amino acid composition in warm-blooded animals
Provedor de dados: 17
Autores: Guang-Zhong Wang; Martin  J. Lercher.
Among eubacteria and archeabacteria, amino acid composition is correlated with habitat temperatures. In particular, species living at high temperatures have proteins enriched in the amino acids E-R-K and depleted in D-N-Q-T-S-H-A. Here, we show that this bias is a proteome-wide effect in prokaryotes, and that the same trend is observed in fully sequenced mammals and chicken compared to cold-blooded vertebrates (Reptilia, Amphibia and fish). Thus, warm-blooded vertebrates likely experienced genome-wide weak positive selection on amino acid composition to increase protein thermostability.

Biased estimates in discrete choice models: the appropriate inclusion of psychometric data into the valuation of recycled wastewater
Provedor de dados: 31
Autores: Gibson,   Fiona L.; Burton,   Michael P.
The introduction of measurement bias in parameter estimates into non-linear discrete choice models, as a result of using factor analysis, was identified by Train et al. (1987). They found that the inclusion of factor scores, used to represent relationships amongst like variables, into a subsequent discrete choice models introduced measurement bias as the measurement error associated with each factor score is excluded. This is an issue for non-market valuation given the increase in popularity of including psychometric data, such as primitive beliefs, attitudes and motivations, in willingness to pay estimates. This study explores the relationship between willingness to pay and primitive beliefs through a case study eliciting Perth community values for...

Autores: Bachinger, Dr. Johann; Fischer, Holger.
Bicropping systems based on forage legumes undersown in winter cereals can  achieve yield and quality improvements with sufficient water supply during the main  growth phase, but fail under dry site conditions (continental climate, sandy soil). To  improve the N-supply without the risk of interspecific water and nutrient competition,  bicropping systems were developed with simultaneously or parallel intercropped nonhardy  grain legumes at in early sown winter cereals or oil seed rape. They were tested  in practice with on-farm experiments carried out in Brandenburg and Bavaria. Besides  a sufficient erosion protection, a significant N-input can be achieved with grain  legumes in autumn especially within rape and early sown winter cereals. But only  cereals...

Bid-Ask Spreads, Volume, and Volatility: Evidence from Livestock Markets
Provedor de dados: 31
Autores: Frank,   Julieta; Garcia,   Philip.
Understanding the determinants of liquidity costs in agricultural futures markets is hampered by a need to use proxies for the bid-ask spread which are often biased, and by a failure to account for a jointly determined micro-market structure. We estimate liquidity costs and its determinants for the live cattle and hog futures markets using alternative liquidity cost estimators, intraday prices and micro-market information. Volume and volatility are simultaneously determined and significantly related to the bid-ask spread. Daily volume is negatively related to the spread while volatility and volume per transaction display positive relationships. Electronic trading has a significant competitive effect on liquidity costs, particularly in the live cattle...

The bifid condylar process is a rare anomaly. Most of the known cases are radiographic findings, mainly in ortopantomography and nuclear magnetic resonance. The condition is usually asymptomatic, while in some cases are associated with ankylosis of the temporomandibular joint. It is reported that the presence of bifid condylar process is not determined by age and gender, but the findings are among the ages of 3 to 67 years, with the average age of 35 years. The present report presents two cases of patients with abnormalities of condylar process detectable through radiographic examination.

Bilateral facial palsy associated with leptospirosis
Provedor de dados: 55
Autores: Silva,Andressa Alves da; Ducroquet,Marcelo; Pedrozo Junior,Jeff Chandler.
Leptospirosis is a zoonosis of worldwide occurrence caused by the spirochete Leptospira interrogans. It is an acute feverish disease with a broad clinical spectrum and follows a characteristic biphasic course. Bilateral facial palsy is a rare clinical condition and the differential diagnosis of its causes is extensive. The objective of this exploratory study, presented as a case report, is to describe the occurrence of bilateral facial palsy as an unusual manifestation of leptospirosis. This suggestion should not be overlooked when analyzing the causes for bilateral facial palsy, and should be considered with other possible differential diagnoses, some of which are potentially fatal.

Bilateral Presence of Axillary Arch Muscle Passing Through the Posterior Cord of the Brachial Plexus
Provedor de dados: 77
Autores: Pillay,Minnie; Jacob,Suja Mary.
The axillary arch can be described as an anomalous muscular slip of latissimus dorsi muscle. In this paper, a rare case of bilateral axillary arch is reported during routine dissection of the axillary region of a 57-year old male cadaver. On both sides, the axillary arch muscle took origin from latissimus dorsi and teres major, and passed upwards through the posterior cord of the brachial plexus, but posterior to the bulk of axillary neurovascular bundle. It then split into two slips: the medial slip was inserted into the root of the coracoid process, while the lateral slip which was intracapsular, was attached to the lesser tubercle, above the attachment of subscapularis. The presence of the muscle has important clinical implications, and the position,...

Bilateral Trade and Economic Growth: The Empirical Evidence Between U.S. and South Korea
Provedor de dados: 31
Autores: Kang,   Hyunsoo; Kennedy,   P. Lynn.
This paper analyzes the relationships between bilateral trade and economic growth in the U.S. and Korean economies. Using quarterly data from 1990 to 2008, the theoretical procedures utilize Ordinary Least Square (OLS) and Seemingly Unrelated Regression (SUR) models under the static model assumption, an Impulse Response Function (IRF) and Forecast Error Variation Decomposition (FEVD) under the Vector Autoregressive (VAR) model, and Granger causality tests. Empirical results indicate a causal relationship between bilateral export growth and economic growth for the U.S. and Korean economies. The export-led growth (ELG) hypothesis is strongly supported by the results of Granger causality tests on Korean exports.

Foetal anatomy seems to be highly promising developing speciality in the recent past. Maxilla is the key to facial skeleton. Its anatomy in general and bilateral variations along with sexual dimorphism in particular are of great surgical and forensic importance.Thirty two maxillae of sixteen human foetuses (21 wks to 34 wks) were considered to measure lengths of infraorbital groove and canal, widths of ends of infraorbital groove, diameters of infraorbital foramen and the distances of latter from infraorbital margin and nasal notch. Groups I (21-25 wks) and II (26-30 wks) foetuses were crucial for bilateral variations for most of the parameters. Distance between infraorbital foramen and nasal notch showed variations on two sides in maximum foetal groups....

Binding to PCNA in Euryarchaeal DNA Replication Requires Two PIP Motifs for DNA Polymerase D and One PIP Motif for DNA Polymerase B
Provedor de dados: 5
Autores: Castrec, Benoit; Rouillon, Christophe; Henneke, Ghislaine; Flament, Didier; Querellou, Joel; Raffin, Jean-paul.
Replicative DNA polymerases possess a canonical C-terminal proliferating cell nuclear antigen (PCNA)-binding motif termed the PCNA-interacting protein (PIP) box. We investigated the role of the PIP box on the functional interactions of the two DNA polymerases, PabPol B (family B) and PabPol D (family D), from the hyperthermophilic euryarchaeon Pyrococcus abyssi, with its cognate PCNA. The PIP box was essential for interactions of PabPol B with PCNA, as shown by surface plasmon resonance and primer extension studies. In contrast, binding of PabPol D to PCNA was affected only partially by removing the PIP motif. We identified a second palindromic PIP box motif at the N-terminus of the large subunit of PabPol D that was required for the interactions of PabPol...

Bacterial biofilms, frequently in association with algae, protozoa and fungi, are found on all submerged structures in the marine environment. Biofilms are responsible for a range of surface‐associated and diffusible signals, which may moderate the settling behaviour of cells, spores and larvae. Thus, marine microorganisms are a new source of bioactive compounds, which enhance or inhibit the settlement of organisms.

In the present study, we screened the biological activity of extracts from the marine sponge Halichondria panicea collected in the Arabian Sea. Crude toxin was obtained by methanol, chloroform-methanol (2:1) and aqueous extraction. Subsequently, the protein concentration of each crude extract was determined. The impact of both sponge methanolic and aqueous extracts was found to increase activities of Na+-K+ ATP-ase and Mg++ ATP-ase. In the case of chloroform-methanol extract, higher concentrations increased acetylcholine esterase (AchE) activity. The methanolic and chloroform-methanol extracts exhibited hemolytic activity on chicken and human erythrocytes, whereas the aqueous extract failed to do so. Methanol and aqueous extracts produced an...

Biochemical and pharmacological study of venom of the wolf spider Lycosa singoriensis
Provedor de dados: 80
Autores: Liu,ZH; Qian,W; Li,J; Zhang,Y; Liang,S.
The wolf spider Lycosa singoriensis is a large and venomous spider distributed throughout northwestern China. Like other spider venoms, the wolf spider venom is a chemical cocktail. Its protein content is 0.659 mg protein/mg crude venom as determined by the Lowry method. MALDI-TOF analysis revealed that the venom peptides are highly diverse and may be divided into three groups characterized by three independent molecular ranges: 2,000 to 2,500 Da, 4,800 to 5,500 Da and 7,000 to 8,000 Da, respectively. This molecular distribution differs substantially from those of most spider venoms studied so far. This wolf spider venom has low neurotoxic action on mice, but it can induce hemolysis of human erythrocytes. Furthermore, the venom shows antimicrobial activity...

Several enzymes that contribute to immune system responses require zinc and copper as trace elements for their activity. We examined zinc and copper levels in two susceptible Balb/c mouse lines and resistant C57bl/6 mice infected with Leishmania major MRHO/IR/75/ER, a prevalent strain that causes cutaneous leishmaniasis in Iran. Serum Zn and Cu were determined by flame atomic absorption spectrophotometry. Higher Cu levels were found in infected C57bl/6 mice and higher Zn levels were found in infected Balb/c mice. Also, Cu/Zn ratios were increased in both the Balb/c and the C57bl/6 mice. We conclude that concentrations of essential trace elements vary during cutaneous leishmaniasis infection and that this variation is associated with...

Autores: Assis,Helena Cristina da Silva de; Nicareta,Lilian; Salvo,Ligia Maria; Klemz,Claudio; Truppel,Jessé Henrique; Calegari,Rossana.
This study aimed to determine the effect of sublethal doses of deltamethrin, using biochemical biomarkers as activities of cholinesterase (ChE), ethoxyresorufin-O-deethylase (EROD) and the Na+K+- ATPase and levels of total cytochrome P450 (CYP450). Fishes received sublethal doses of deltamethrin and were sacrificed after 96 h of exposure. Samples of gills, heart, brain, liver and muscle were collected for enzymatic analyses. Deltamethrin inhibited the activity of the gills and heart Na+ K+-ATPase, induced the liver total CYP450, as well as the liver EROD activity. The activity of the ChE was not inhibited by deltamethrin. Deltamethrin altered the hepatic metabolism and the normal ionic flux in Ancistrus multispinis.

Two syntopic morphotypes of the genus Hypostomus - H. nigromaculatus and H. cf. nigromaculatus (Atlântico Stream, Paraná State) - were compared through the allozyme electrophoresis technique. Twelve enzymatic systems (AAT, ADH, EST, GCDH, G3PDH, GPI, IDH, LDH, MDH, ME, PGM and SOD) were analyzed, attributing the score of 20 loci, with a total of 30 alleles. Six loci were diagnostic (Aat-2, Gcdh-1, Gpi-A, Idh-1, Ldh-A and Mdh-A), indicating the presence of interjacent reproductive isolation. The occurrence of few polymorphic loci acknowledge two morphotypes, with heterozygosity values He = 0.0291 for H. nigromaculatus and He = 0.0346 for H. cf. nigromaculatus. F IS statistics demonstrated fixation of the alleles in the two morphotypes. Genetic identity (I)...

Provedor de dados: 69
Autores: Montealegre,Jaime; Valderrama,Luis; Herrera,Rodrigo; Besoaín,Ximena; Pérez,Luz M.
Wild (Th11, Th12 and Th650) and mutant (Th11A80.1, Th12A40.1, Th12C40.1 and Th650-NG7) Trichoderma harzianum strains were stored for 180 days at 5ºC or at 22ºC, in two types of soils. Strains recovered at 90, 120 and 180 days from the two types of soils, retained their full capacity to biocontrol Rhizoctonia solani 618, that produces crown and root rot of tomatoes. Recovery, estimated as colony forming units (cfu) of the wild and mutant strains, showed that all increased their cfu after storage independently of the type of soil and temperature, although kinetic behavior differed among strains. Ratios of recovery after storage in type B soil/ type A soil or at 22ºC/5ºC, higher or lower than one respectively, allowed to establish that Th11 and Th12 were the...

Bioconversion of apple pomace into a multienzyme bio-feed by two mixed strains of Aspergillus niger in solid state fermentation
Provedor de dados: 69
Autores: Zhong-Tao,Sun; Lin-Mao,Tian; Cheng,Liu; Jin-Hua,Du.
Apple pomace is a wasted resource produced in large quantities and its deposit has caused serious environmental problems, so it is significance to make the full utilization of the residues. The objectives of this work were to produce multienzyme bio-feed, biodegrade the anti-nutritional factors such as pectin and tannins in apple pomace, and obtain the nutritional enrichment of the fermented substrate. The mixture of apple pomace and cottonseed powder (1:1, w/w), supplemented with 1% (w/w) (NH4)2SO4 and 0.1% (w/w) KH2PO4, was proved to be the optimum medium for the mixed strains of Aspergillus niger M2 and M3 (2:1, w/w). The activities of pectinase, proteinase and cellulase achieved 21168 u/g, 3585 u/g and 1208u/g, and the biodegradation rates of pectin...

As the first phase of a knowledge engineering study of biocuration workflows, we performed a preliminary task-modeling exercise on seven separate bioinformatics systems. This involved constructing UML activity diagrams from detailed interviews with curators in order to understand the organization of the process the biocurators used to populate their system. The objective of this work was to identify common patterns within the workflows where we might apply text mining methods to accelerate curation. We compiled a number of workflows in a common format but were largely unable to consolidate these structures into a formal structure that facilitated comparison across workflows.

Los contaminantes orgánicos persistentes poseen propiedades tóxicas, son resistentes a la degradación, se bioacumulan y son transportados por el aire, el agua y las especies migratorias a través de las fronteras internacionales; en consecuencia se depositan lejos del lugar de su liberación, acumulándose en ecosistemas terrestres y acuáticos. Para atender a esta problemática a nivel mundial se firmó el 23 de mayo de 2001 el Convenio de Estocolmo. Aunque por ahora los COP estan prohibidos en la mayoria de los países, todavía existen en el mundo muchos sitios contaminados con estas sustancias. La remediación de sitios que presentan contaminantes orgánicos persistentes requiere consideraciones distintas a las contempladas en la recupe-ración por contaminación...

Biodegradation of 2,4 dichlorophenol by Pleurotus ostreatus DSM 1833
Provedor de dados: 52
Autores: Silva,Heloisa Helena Batista da; Schneider,Andréa Lima dos Santos; Wisbeck,Elisabeth; Furlan,Sandra Aparecida.
This work aimed to investigate the capacity of Pleurotus ostreatus DSM 1833 to degrade 2,4-dichlorophenol, important pollutant found in the wastewaters of the paper and cellulose industry. Using a factorial design 2², the concentrations of glucose and 2,4-dichlorophenol varied between 0 and 10g.L-1 and 5 and 30mg.L-1, respectively. The best global biodegradation rate was obtained using 30 mg.L-1 of 2,4- dichlorophenol in the absence of glucose. This culture medium was used for scaling up the process, resulting in a global biodegradation rate of 0.47mg.L-1.h-1. A comparative test between an inoculated medium and an abiotic control demonstrated that 54.1% of 2,4- dichlorophenol degradation could be attributed to the presence of P. ostreatus.

In this study, the potential for using an inoculum composed of a mixed-culture of bacteria and fungi, isolated from a landfarming at the Paulínia Oil Refinery, Brazil, to degrade oil residues generated in the process of petroleum refinement was investigated. The isolation of these microorganisms was carried out beforehand, assuming that they would be better adapted to petroleum hydrocarbons, as the landfarming consisted of an area impacted by the deposit of such compounds. The Bartha and Pramer respirometric test was used to measure the rate of biodegradation of the hydrocarbons by the mixed-culture of microorganisms via the evolution of CO2. The results obtained with respect to the efficiency of biodegradation showed no significant differences...

During the European Commission's Framework Six Programme, HERMES, we investigated three main areas along the European margin, each characterized by the presence of seep-related structures exhibiting different intensity of activity and biological diversity. These areas are: (1) the Nordic margin with the Hakon Mosby mud volcano and many pockmarks, (2) the Gulf of Cadiz, and (3) the eastern Mediterranean with its hundreds of mud volcanoes and brine pool structures. One of the main goals of the HERMES project was to unravel the biodiversity associated with these seep-associated ecosystems, and to understand their driving forces and functions, using an integrated approach. Several multidisciplinary research cruises to these three areas provided evidence of...

Biodiversity Quality: a paradigm for biodiversity
Provedor de dados: 17
Autores: Alan Feest; Timothy Aldred; Katrin Jedamzik.
The internationally accepted definition of biodiversity creates difficulty in measuring difference and change. The authors suggest that well-sampled data can be used to generate a range of numerical indices reflecting species group characteristics/functionality (Species Richness, Simposons Index, Population Density, Biomass and Species Conservation Value) that can be viewed in combination to create a picture of biodiversity quality. This overall approach has considerable advantages over the currently accepted Convention on biological Diversity definition based on the &amp;#x22;variability&amp;#x22; of genes, species and ecosystems, since the numerical expression of the indices allows the probability of difference between biodiversity quality trends and...

Provedor de dados: 80
Autores: Nikbakhtzadeh,MR; Akbarzadeh,K; Tirgari,S.
The genus Pachycondyla is a large group of ants in the Ponerini tribe, known mostly from tropical and subtropical regions. Pachycondyla sennaarensis, the so-called Samsum ant in the Middle East, is distributed throughout the African tropics, Arabian Peninsula and Iran, where it is responsible for many cases of insect-induced dermal lesions and systemic reactions in humans. Populations of P. sennaarensis were studied in two regions of Iran and some aspects of their biology, ecology and medical importance are herein presented. Colonies of P. sennaarensis contain less than 850 workers that live in complicated underground galleries approximately one meter deep. Because of the harsh weather conditions of southern Iran, they can survive only in human disturbed...

Bioeconomic model of the dynamics of fisheries facing global economic and environment changes: the French Guyana shrimp fishery
Provedor de dados: 5
Autores: Chaboud, Christian; Thebaud, Olivier.
In the past two decades, the French Guyana shrimp fishery has known dramatic evolutions, largely driven by global changes. On the economic side, two major driving factors are the globalization of the shrimp market, with a decreasing trend in real prices, an d the long-term increase in fuel prices worldwide. On the environmental side, recruitment of the two main species of shrimp targeted in the fishery seems to have decreased over the last decade. This decrease is probably related to hydroclimatic modifications linked to global change. It is important to assess the adaptive capacity of the fishery facing such changes, as well as the relevance of past and future public policies to improve this capacity.  A key component of this adaptive capacity is the way...

BIO-ENERGY FROM WINERY BY-PRODUCTS: A NEW MULTIFUNCTIONAL TOOL FOR THE ITALIAN WINE DISTRICTS
Provedor de dados: 31
Autores: Begalli,   Diego; Codurri,   Stefano; Gaeta,   Davide.
This paper aims to investigate if the legislation will allow the production of energy from winery by-products and how this can contribute to multifunctionality of the wine makers’ income. A medium size winery was selected and an anaerobic digestor process was simulated using the company’s data. The main methods of financial evaluation were studied to create information to see if the project concepts were valid. The results highlight the positive level of earnings that the project will generate due to the high level of methane included in the pressings that could be transformed in energy, the short period needed for obtaining methane and the recent substantial level of government support both in Green Certificates and financing of the initial cost of the...

Bio-energy production in the sugar industry: an integrated modeling approach
Provedor de dados: 31
Autores: Haque,   Imdadul; Rozakis,   Stelios; Ganko,   Ewa; Kallivroussis,   Leonidas.
Recent reforms in the Common Agricultural Policy and the sugar regime caused serious concerns for the future of the European sugar industry. At the same time, the European Commission considers transportation bio-fuels as a key factor for reducing reliance on imported fuels, emission levels of greenhouse gases and to meet rural development goals. Matching the sugar sector with bio-ethanol production may create opportunities for sustainable management of the existing sugar industry infrastructure and also serve bio-fuel policy targets. A partial equilibrium economic model is used in order to evaluate the shift from sugar to bio-ethanol production in Thessaly, Greece. In the agricultural feedstock supply and industrial processing sub-models are articulated...

Bioethanol production from germinated grain by inherent  enzymes
Provedor de dados: 21
Autores: Kádár, Zsófia; Christensen, Anne Deen; Thomsen, Mette Hedegaard; Thomsen, Anne Belinda.
The malting in brewing process develops enzymes that are required to hydrolyze the complex starch in grain into simple fermentable sugars. These proceed the three following steps: Steeping encourages germination to start, germination prepares the conversion of the starch to sugars, and kilning stops the germination.  In this study, a method for bioethanol production from rye grain was developed by utilizing the inherent amylase activity from germination of the seed. Grain germination was performed in two steps (steeping, germination) under different conditions, where the effect of temperature, duration and humidity was examined on amylase activity and final ethanol yield. Commercial enzymes were used for reference experiments.  Simultaneous...

The objective of this study was to detect the presence of acyl homoserine lactones (AHLs), signal molecules of the quorum sensing system in biofilm formed by Hafnia alvei strains. It also evaluated the effect of synthetic quorum sensing inhibitors in biofilm formation. AHLs were assayed using well diffusion techniques, thin layer chromatography (TLC) and detection directly in biofilm with biomonitors. The extracts obtained from planktonic and sessile cell of H. alvei induced at least two of three monitor strains evaluated. The presence of AHLs with up to six carbon atoms was confirmed by TLC. Biofilm formation by H. alvei was inhibited by furanone, as demonstrated by 96-well assay of crystal violet in microtitre plates and by scanning electron microscopy....

Biofouling protection for marine underwater observatories sensors
Provedor de dados: 5
Autores: Delauney, Laurent; Compere, Chantal; Lehaitre, Michel.
These days, many marine autonomous environment monitoring networks are set up in the world. Such systems take advantage of existing superstructures such as offshore platforms, lightships, piers, breakwaters or are placed on specially designed buoys or deep sea fix stations. The major goal for these equipments is to provide in real time reliable measurements without costly frequent maintenance. These autonomous monitoring systems are affected by a well known phenomena in seawater condition which is biofouling. Consequently, such system without efficient biofouling protection is hopeless. This protection must be applied to the sensors and to the underwater acoustic communication equipments.

Biofuel policies and the environment: the effects of biofuel feedstock production on climate, water quality and biodiversity
Provedor de dados: 31
Autores: Lankoski,   Jussi E.; Ollikainen,   Markku.
In this paper we examine the multiple environmental effects of policies promoting biofuel production from agricultural crops. We develop theoretical and empirical frameworks and provide an integrated economic and ecological modelling approach: an economic model of farmers’ decision making is combined with a biophysical model predicting the effects of farming practices on crop yields and multiple environmental effects. The analysed environmental effects include GHG emissions over the life cycle, nitrogen and phosphorus runoff, herbicide runoff and the quality of wildlife habitats. Model is applied to crop production in Finland. We found that the overall environmental performance of alternative land use types is mainly driven by the value of CO2-eq emissions...

Biofuels, Growth and Agricultural Development
Provedor de dados: 31
Autores: Msangi,   Siwa.
Global projections for increasing food demand combined with increasing demand for energy from all sources – including crop-based biofuels – point towards greater stress on food systems and their supporting ecosystems. In many parts of the world, increasing household incomes has translated into increasing demands for energy, of which transportation fuel comprises a fast-growing share. Accompanying the world’s steady population growth is an increasing demand for food and the necessary feedstuffs to fuel the requisite increases in livestock production. The combination of these two trends will inevitably lead to greater stresses and demands on the natural resource base and eco-systems that underlie the world’s food and energy production systems – such as land...

Biofuels: Political/Economic Boondoggle or Energy Salvation for Western States?
Provedor de dados: 31
Autores: Young,   Douglas L.
Nearly all western states lack comparative advantages for producing corn for ethanol and oilseeds for biodiesel. Despite this disadvantage, most western states have legislated incentives for production of biofuels. Unfavorable changes in price relationships, high transportation costs for imported feedstocks, and tight credit markets in 2008 and 2009 led to bankruptcies and plant closures at a disproportionate rate in the western biofuel industry. Policy makers in western states are advised to fund research and development for bioenergy and biofuel feedstocks in which they have a comparative advantage. These include forestry by-products, food processing and crop residues, and livestock wastes.

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where...

Biofumigation auch gegen pflanzenparasitische Nematoden?
Provedor de dados: 21
Autores: Eder, Reinhard; Roth, Irma; Zinsstag, Christof; Koch, Walter.
Biofumigation refers to a biological method to reduce diseases, pests and weeds in  the soil which is suitable for organic production systems. Cruciferous plants with a  high level of Glucosinolates are grown for about two months in the field. To achieve  the biofumigation effect, the intercrop is mulched during full bloom and rapidly  incorporated into the soil. The Gluconisolates are converted during biological  degradation into volatile substances toxic for certain diseases or pests. Nematodes  are also sensitive to these substances and are reduced thereby. Besides using the  incorporation of fresh plant material, pellets made of dried cruciferous plants and sold  as fertilizer might be an alternative approach for nematode control. The pellets are...

Biofumigation zur Bekämpfung von Verticillium dahliae
Provedor de dados: 21
Autores: Michel, Dr Vincent.
Cruciferous plants with high contents of glucosinolates can be used to control soilborne  diseases. During the degradation of such plants, the glucosinolates are  transformed into isothio- and thiocyanates. These molecules are volatile and toxic,  therefore, this method is called biofumigation. In this context, the efficacy of two brown  mustard (Brassica juncea) and one canola (Brassica napus) cultivars to reduce the  number of Verticillium dahliae microsclerotia was tested in pot trials. Verticillium  dahliae is the causal agent of verticillium wilt of a large number of important crops.  Microsclerotia are the surviving structures of V. dahliae in the soil. A strong decrease  of the number of microsclerotia was observed using the high...

Während zwei Jahren wurden Versuche, zusammen mit der ACW Wädenswil durchgeführt, um die Chalara- Erregerdichte im Boden vor einer Karottenkultur, mit Biofumigation zu reduzieren. Dabei wurde im Frühjahr vor einer Karottenkultur Brauner Senf angebaut und zur Blüte gemulcht und eingearbeitet. Weder im Boden noch an den Karotten konnte dabei eine Reduktion des Schaderregers beobachtet werden. Die fehlende Wirkung hatte wahrscheinlich folgende Gründe: Die Grünmasseentwicklung des Senfes war zu gering, und die Einarbeitung zu wenig tief.

Biogeochemical controls on productivity and particle flux in the coastal Antarctic Sea Ice Environment
Provedor de dados: 5
Autores: Carson, Damien Stuart.
In order to trace modern processes in the ocean and reconstruct past oceanic conditions, reliable tracers of oceanic processes such as productivity, nutrient utilisation and export production need to be developed. This study therefore assessed a suite of geochemical proxies in the coastal Antarctic sea ice environment over two growing seasons (2004-2006). Time series measurements of productivity and export production were carried out over two contrasting growing seasons in Ryder Bay, a coastal embayment on the Western Antarctic Peninsula with a heavy sea ice influence. Ryder bay exhibits intense primary production during the short ice-free spring and summer months and particle export occurs as an intense period of sedimentation following surface water...

Autores: Bachraty, Charleyne; Legendre, P.; Desbruyeres, Daniel.
The discovery of deep-sea hydrothermal vent fauna, kilometres deep in the oceans, is a great achievement of 20th-century marine biology. The deep-sea hydrothermal food web does not directly depend on the sun's energy. Vent communities rely primarily on trophic associations between chemoautotrophic bacteria and consumers A small. number of endemic taxa are adapted to the inhospitable vent environments that are distributed along ridge crests. Where these vent communities originated and how they dispersed are among the important questions ecologists must answer. Here, by statistical analysis of the most comprehensive database ever assembled about deep-sea hydrothermal fauna, we delineate six major hydrothermal provinces in the world ocean and identify seven...

Biogeography and comparative cytogenetics between two populations of Hoplias malabaricus (Bloch, 1794) (Ostariophysi: Erythrinidae) from coastal basins in the State of Bahia, Brazil
Provedor de dados: 83
Autores: Jacobina,Uedson Pereira; Affonso,Paulo Roberto Antunes de Mello; Carneiro,Paulo Luiz Souza; Dergam,Jorge Abdala.
The species Hoplias malabaricus is a predator fish found in nearly all cis-Andean basins. From a cytogenetic point of view, this species comprises, at least, seven differentiated karyomorphs. Several localities have been formerly analyzed in Brazil, however, some regions, such as Bahia State, remain underrepresented. Recently, the Brazilian Environment Ministry classified both Itapicuru and Contas river basins (entirely located within Bahia territory) as priority conservation areas, whose biodiversity status lacks enough information. Therefore, the goal of the present work was to characterize, cytogenetically, populations of H. malabaricus from both basins, by using conventional staining, Ag-NOR and C-banding techniques. All specimens presented a diploid...

Biogeography of Mindoro mosses
Provedor de dados: 16
Autores: Linis, V.C.
The moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum...

Der biologische Landbau steht für Vielfalt. Dass dem so ist, zeigen viele wissenschaftliche Studien. Biobauern erbringen im Vergleich zu ihren konventionellen Kollegen deutliche Mehrleistungen zugunsten der Biodiversität. Biobetriebe haben je nach Höhenlage zwischen 46 und 72 Prozent mehr naturnahe Flächen und beherbergen 30 Prozent mehr Arten sowie 50 Prozent mehr Individuen als nicht-biologisch bewirtschaftete Betriebe. Die geringere Anbauintensität und der höhere Anteil an naturnahen Flächen führen dazu, dass viele seltene und gefährdete Pflanzen- und Tierarten auf Biobetrieben vorkommen.

Biological activity and persistence of pirimiphos-methyl applied to maize grain at different temperatures
Provedor de dados: 91
Autores: Silveira,Rodrigo D.; Faroni,Lêda R. A.; Guedes,Raul N. C.; Queiroz,Maria E. L. R.; Pimentel,Marco A. G.
The expansion of dryeration may impose a further problem for insect control with protectants - the high grain temperatures during insecticide spraying. To assess the impact of this procedure on insecticide activity, maize grains at different temperatures (25, 30, 35, 40 and 45 °C) were sprayed with pirimiphos-methyl. Residue analyses were carried out every 30 days and insecticide biological activity towards Sitophilus zeamais and Tribolium castaneum was assessed every 15 days throughout the experimental period of 90 days. Insect mortality was evaluated after 48 h. Pirimiphos-methyl residue decreased with increased storage time and grain temperature during spraying. Similar trends were also observed for mortality of S. zeamais and T. castaneum, which...

Biological Activity of Essential Oils from Leaves and Fruits of Pepper Tree (Schinus molle L.) to Control Rice Weevil (Sitophilus oryzae L.)
Provedor de dados: 117
Autores: Benzi,Verónica; Stefanazzi,Natalia; Ferrero,Adriana A.
Rice weevil (Sitophilus oryzae L.) is a primary insect pest of stored grain. The development of resistance resulted in the application of synthetic insecticides. In recent years many plant essential oils have provided potential alternatives to currently used insect control agents. The Brazilian pepper tree (Schinus molle L. var. areira (L.) DC.) (Anacardiaceae) has different biological properties such as insecticidal activity. In this study, repellent, fumigant activity, nutritional indices, and feeding deterrent action were evaluated on S. oryzae adults. Filter paper impregnation was used to test fumigant toxicity, whereas treated whole wheat was used to evaluate repellent activity and a flour disk bioassay was done to evaluate feeding deterrent action...

Biological control of invasive plant species: stochastic economic analysis
Provedor de dados: 31
Autores: Chalak-Haghighi,   Morteza; Ruijs,   Arjan; van Ierland,   Ekko C.
We analysed to what extent the stochastic effects of two biological control agents (i.e. weevils and mycoherbicides) affect the optimal choice of Californian thistle control. A stochastic, dynamic optimisation model was set up to analyse strategies that maximise the expected net present values. We analysed the cost-effective strategies to control the thistle for deterministic and stochastic cases. Results show that the stochasticity of the efficacy of weevils does not affect the optimal strategy. Compared to the deterministic case, however, mycoherbicides will be introduced at a higher level of weed density if we take the stochastic effect of mycoherbicides into account.

The Laser used correctly in the medical practice offers clear advantages compared with traditional therapies. The improvement and even the elimination of many significant skin lesions can be achieved with reduced risks to patients. However, it is important to keep security measures and understand the possible effects on an experimental model. The chick embryo is a good model to evaluate the direct effects of non-ionizing radiation for its easy handling and availability. The purpose of this communication is to show our histological findings in organs of the chick embryo with and without protective barrier to be subjected to radiation excimer. We used the following issuers: intense pulsed light (excimer Xe-Cl laser of 308 nm wavelength). It was irradiated...

The dynamic of plant communities is strongly influenced by biological interactions. We studied the effects of Eichhornia azurea on the growth of the free-floating macrophytes Eichhornia crassipes, Salvinia minima, Salvinia auriculata and Limnobium laevigatum. The experiments were carried out in three lakes of the upper Paraná river floodplain. We used 0.5 m side squares where these species grew for 11 days (S. auriculata and L. laevigatum) and 17 days (E. crassipes and S. minima), in the presence and absence of E. azurea. There were no significant differences between the relative growth rates of macrophytes growing in the absence and presence of E. azurea. The relative interaction index showed the existence of competition between E. azurea and L....

Farming is in the midst of a major transformation—not only in technology and production practices, but also in size of business, resource control and operation, business model and linkages with buyers and suppliers. Both the livestock and grain sectors are changing from an industry dominated by family-based, small and modest size, relatively independent firms to one of generally larger businesses following an industrial business model that are more tightly aligned across the value chain. We describe some of the fundamental concepts and characteristics of biological manufacturing and then illustrate these characteristics with a brief description of three modern farming businesses. The characteristics include: attribute driven or differentiated products, a...

Biomass equations for forest regrowth in the eastern Amazon using randomized branch sampling
Provedor de dados: 36
Autores: Ducey,Mark Jonathan; Zarin,Daniel Jacob; Vasconcelos,Steel Silva; Araújo,Maristela Machado.
Forest regrowth occupies an extensive and increasing area in the Amazon basin, but accurate assessment of the impact of regrowth on carbon and nutrient cycles has been hampered by a paucity of available allometric equations. We develop pooled and species-specific equations for total aboveground biomass for a study site in the eastern Amazon that had been abandoned for 15 years. Field work was conducted using randomized branch sampling, a rapid technique that has seen little use in tropical forests. High consistency of sample paths in randomized branch sampling, as measured by the standard error of individual paths (14%), suggests the method may provide substantial efficiencies when compared to traditional procedures. The best fitting equations in this...

Biomass production and phosphorus use of forage grasses fertilized with two phosphorus sources
Provedor de dados: 90
Autores: Ramos,Sílvio Júnio; Faquin,Valdemar; Rodrigues,Carlos Ribeiro; Silva,Carlos Alberto; Boldrin,Paulo Fernandes.
A major constraint to agricultural production in acid soils of tropical regions is the low soil P availability, due to the high adsorption capacity, low P level in the source material and low efficiency of P uptake and use by most of the modern varieties grown commercially. This study was carried out to evaluate the biomass production and P use by forage grasses on two soils fertilized with two P sources of different solubility. Two experiments were carried out, one for each soil (Cambisol and Latosol), using pots filled with 4 dm³ soil in a completely randomized design and a 4 x 2 factorial scheme. The treatments consisted of a combination of four forage plants (Brachiaria decumbens, Brachiaria brizantha, Pennisetum glaucum and Sorghum bicolor) with two P...

Female Wistar rats were randomly divided into five groups containing 12-14 rats: control I (118 days old), control II (139 days old), suspended (tail suspension for 28 days), suspended-released (released for 21 days after 28 days of suspension), and suspended-trained (trained for 21 days after 28 days of suspension). We measured bone resistance by bending-compression mechanical tests of the entire proximal half of the femur and three-point bending tests of diaphyseal cortical bone. We determined bone microstructure by tetracycline labeling of trabecular and cortical bone. We found that tail suspension weakened...

Provedor de dados: 45
Autores: Martins,L.G.A.; Raiser,A.G.; Richter,R.K.; Braga,F.V.A.; Rappeti,J.C.; Oliveira,A.N.C.
Realizou-se uma série de biópsias cardíacas em cães para testar o acesso toracoscópico, utilizando-se oito cães sem raça definida, sob condições de manejo e alimentação adequados. A abordagem à cavidade torácica foi feita por meio de cirurgia torácica videoassistida e o instrumental utilizado para remoção do fragmento de miocárdio foi o convencional em lugar das pinças de videocirurgia. A eficácia do procedimento foi confirmada pelo tempo decorrido entre as incisões, a execução da biópsia e a sutura do tórax, com duração média de 15 minutos. A cirurgia torácica videoassistida para biópsias cardíacas foi considerada segura e adequada, minimizando o desconforto pós-operatório dos pacientes submetidos ao acesso torácico.

Autores: Kádár, Zsófia; Oleskowicz-Popiel, Piotr; Schmidt, Jens Ejbye; Thomsen, Anne Belinda.
Organic agriculture is one sustainable alternative to avoid the negative environmental effects often caused by conventional agriculture. BioConcens is an interdisciplinary project aims at developing new biorefinery concept and processes for co-production of bioethanol, biogas and animal feed based on resources from organic agriculture (clover grass, straw) and associated food processing (whey). Bioenergy produced in organic agriculture can reduce its dependency of fossil fuels and decrease greenhouse-gas emission, and at the same time it is important that carbon and nutrients cycle are not influenced negatively. Biogas can be produced from any carbon rich waste/by-product, which can be further utilized in combined heat and power plant to produce heat and...

Bio-Richtlinien für die Zukunft – Wegweiser statt Vorschriften

Autores: Schmid, Otto.
Im Hinblick auf die Richtlinien besteht heute ein doppeltes Dilemma: Zum einen geben immer öfter staatliche Stellen – anstatt engagierter Bio-Bauern – die Inhalte der Regeln vor. Einst suchte der ökologische Landbau die staatliche Anerkennung, nun wird sie von manchen Akteuren kritisch gesehen. Gewünscht werden hingegen Konzepte, die den Bauern wieder mehr Eigenverantwortung geben. Wie soll das geschehen? Zum anderen ist die Gesellschaft zwar bereit, den Bio-Landwirten ihre positiven gesellschaftlichen Leistungen zu bezahlen, allerdings sind diese in den Richtlinien nicht immer auf den ersten Blick erkenn- und messbar.

Biosecurity Economics: Conflicting results in evaluation criteria
Provedor de dados: 31
Autores: Goswami,   Sarah L.
Determining the optimal policy response to a species invasion is a multidimensional problem. The choice between eradication or containment has social, environmental, political and economic dimensions. Often, economic evaluation is used as a basis to underpin policy decisions. However, under certain conditions economic evaluation criteria may provide conflicting results. Deterministic factors, such as rate of spread, degree of damage and the time until detection, are derived for identifying when caution must be taken with the results of economic evaluation criteria. The conditions under which conflicting results may be obtained between NPV and BCR are identified and linked to policy implications.

Biosecurity, Terrorism, and Food Consumption Behavior: Using Experimental Psychology to Analyze Choices Involving Fear
Provedor de dados: 31
Autores: Just,   David R.; Wansink,   Brian; Turvey,   Calum G.
How would a possible food safety scare influence food consumption? Using techniques from experimental psychology, a study of 103 lunchtime participants suggests that a food scare--avian influenza--would decrease consumption of the affected food by 17% if the subjects believed it was naturally occurring, and by 26% if they believed it was the result of terrorism. While individual consumption decreased, very few eliminated all consumption of the affected food. We argue that experimental psychology is essential when attempting to study behavior in food safety where hypothetical scenarios and surveys would not capture the emotional nature of the response.

The study of planktonic foraminifera of the Gurpi formations at Lar area (Kuh-e-kurdeh section) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Five biozones were determined. Biozones I (Globotruncanita elevata zone) and II (Globotruncana ventricosa zone) and III (Radotruncana calcarata zone) indicate the Early Campanian and Middle and Late Campanian, respectively. Biozones IV (Globotruncanita stuarti zone) and V (Gansserina gansseri zone) suggest the Early and Middle Maastrichtian, respectively. In the Late Maastrichtian, due to decreasing in water depth at the study area, Abathomphalus mayaroensis zone defined in Tethysian domain was not recognised.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;

Biotechnological approaches for plant viruses resistance: from general to the modern RNA silencing pathway
Provedor de dados: 52
Autores: Rodrigues,Silas Pessini; Lindsey,George G.; Fernandes,Patricia Machado Bueno.
Virus diseases are significant threats to modern agriculture and their control remains a challenge to the management of cultivation. The main virus resistance strategies are based on either natural resistance or engineered virus-resistant plants. Recent progress in understanding the molecular mechanisms underlying the roles of resistance genes has promoted the development of new anti-virus strategies. Engineered plants, in particular plants expressing RNA-silencing nucleotides, are becoming increasingly important and are likely to provide more effective strategies in future. A general discussion on the biotechnology of plant responses to virus infection is followed by recent advances in engineered plant resistance.

Biotin-avidin sandwich elisa with specific human isotypes IgG1 and IgG4 for Culicidae mosquito blood meal identification from an epizootic yellow fever area in Brazil
Provedor de dados: 80
Autores: Marassá,AM; Paula,MB; Gomes,AC; Consales,CA.
With a view toward investigating the feeding behavior of Culicidae mosquitoes from an area of epizootic yellow fever transmission in the municipalities of Garruchos and Santo Antônio das Missões, Rio Grande do Sul State, Brazil, specimens were collected by aspiration from September 2005 to April 2007. The engorged females were submitted to blood meal identification by enzyme-linked immunosorbent assay (ELISA). A total of 142 blood-engorged samples were examined for human or monkey blood through species-specific IgG. Additional tests for specificity utilizing isotypes IgG1 and IgG4 of human monoclonal antibodies showed that only anti-human IgG1 was effective in recognizing blood meals of human origin. The results indicated a significant difference (p =...

Bio-Weizenqualität 2009
Provedor de dados: 21
Autores: Dierauer, Hansueli; Böhler, Daniel.
Die Bio-Weizenqualität gibt immer wieder Anlass zu regen Diskussionen. Die untersuchten Bioweizen der letzten drei Jahre erreichten eine gute Backqualität. Sie ist vergleichbar mit der Qualität von Weizen aus Nicht-Bio-Anbau. Dies obwohl Bioweizen bei den Laboruntersuchungen in der Regel tiefere Werte erreicht, als Weizen aus intensiver Produktion. Auch in den Exaktversuchen liegen die Proteinwerte der verschiedenen Winterweizensorten aus biologischer Produktion im Durchschnitt ein Prozent unter denjenigen aus konventioneller Produktion.  Die Nachfrage nach Mehl mit einem hohen Feuchtglutengehalt nimmt zu, weil sich die Verarbeitung verändert (lange Triebführung, industrielle Verarbeitung, Kühl- oder Tiefkühllagerung der Teiglinge). 2/3 der gesamten...

Autores: Dierauer, Hansueli; Böhler, Daniel.
Wie im Jahr 2008 wurden auch 2009 im Rahmen des Versuchsnetzes mit acht kantonalen Fachstellen aus der ganzen Schweiz acht Bioweizensorten in Streifen geprüft. Die Koordination der Versuche und die Auswertungen erfolgten durch das FiBL. Die Sorten wurden mit Hilfe der ART (Jürg Hiltbrunner), welche die Exaktversuche durchführt, ausgelesen und mit der Fachkommission Ackerkulturen der Bio Suisse abgesprochen. Die Streifenversuche dienen als Vorstufe zur Einführung neuer Sorten in die Praxis und haben auch einen wichtigen Democharakter. Sie sind eine Ergänzung zur Biosortenprüfung des Reckenholzes. Bevor eine Sorte in die empfohlene Sortenliste der Bio Suisse aufgenommen wird, sollte sie mindestens ein Jahr im FiBL-Versuchsnetz geprüft sein. Insgesamt wurden...

Zuckerrüben gelten als Bodenverbesserer, sind Nährstoffzehrer und nutzen als Tiefwurzler die Vorräte im Unterboden. Zuckerrüben sind eine Bereicherung für getreidebetonte Fruchtfolgen, sind aber arbeitsaufwändig im Anbau. Dank den Erfahrung und Auswertungen aus einigen Jahren Biozuckerrübenanbau in der Schweiz sowie Versuchen der Agroscope ART ist es heute möglich, mit einiger Sicherheit erfolgreich Zuckerrüben biologisch zu kultivieren.

We examined bird diversity in relation to land use and socioeconomic indicators in Leipzig, Germany. We used neighborhood diversity (ND) and bivariate correlation to show that the potential to experience biodiversity in a city is associated with population density, household income, unemployment, and urban green space. People living in urban districts with high socioeconomic status experience the highest species richness around their homes, whereas lower social status increases the chance of living in species-poor neighborhoods. High-status districts are located along forests, parks, and rivers that have a high quantity and quality of green space. However, green space in general does not guarantee high bird diversity. We conclude that bird diversity...

El impulso inicial de este extraño proyecto, viene de un interés que compartimos sobre ciertas formas híbridas de la cultura que se escenifican de manera contundente en fiestas populares como la de la Mama Negra, en Latacunga, en la Sierra del Ecuador. Si bien esta fiesta, -con antecedentes en tradiciones del Norte de África y Sur de España,- fue traída a América por los conquistadores, aquí se ha ido transformando a través de los siglos y ha incorporado a su visualidad y ritualidad, un bagaje de contenidos simbólicos locales -y actuales- que se superponen sobre los anteriores, creando así una madeja insondable de significados.

Ved at blande to forskellige afgrøder på samme mark vil der i teorien være visse fordele især mhp. at minimere angreb af svampesygdomme. Fx viste en økologisk landmand i år, at vintertriticale i blanding med rug medførte forsinkede gulrustangreb på triticalen, hvormed kernerne kunne nå at  udvikle sig. Udover en forebyggende effekt mod svampesygdomme kan blandingsafgrøder også være med til at holde ukrudtstrykket nede.

Estima-se que, atualmente, 25% da produção de grãos produzidos no Brasil são perdidos nas fases de colheita e pós-colheita, mas esta realidade pode ser minimizada caso o País estimule a estocagem da produção. Com o intuito de promover, de forma economicamente viável, a armazenagem da produção nas fazendas, objetivou-se estudar blocos de concreto para utilizá-los na construção de silos cilíndricos de alvenaria. Desenvolveram-se blocos com geometria especial, moldados nos traços (cimento: areia) de 1:3, 1:4 e 1:6, os quais foram analisados pelos testes de absorção de água, resistência á compressão e ao cisalhamento, submetidos a dois tipos de cura: natural e submersa.

Autores: Serefhanoglu,Kivanc; Turan,Hale; Timurkaynak,Funda Ergin; Arslan,Hande.
This prospective case-control study was conducted from October 2003 to June 2007 to evaluate risk factors for multidrug resistance among extended-spectrum-b-lactamase-producing Escherichia coli and Klebsiella spp. (ESBL-EK) isolates in blood cultures. All adult patients (&gt;18 years old) whose blood cultures grew ESBL-EK during the study period were included. An ESBL-EK isolate was defined as MDR if it was resistant to at least one member of following two classes of antibiotics: aminoglycosides (amikacin, gentamicin, or netilmycin) and fluoroquinolones (ofloxacin, or ciprofloxacin). Case patients were those with a MDR ESBL-EK isolate, and control patients were those with a non-MDR ESBL-EK isolate. A total of 94 bloodstream infections, including 37 (39,4%)...

Vanaja Ramprasad  was one of the members newly elected to the ten-member World Board of the International Federation of Organic Agriculture Movements. She is the director of India's Green Foundation and she has a passionate interest in “the real reasons for third world poverty and hunger”. In this interview she explains: "My interest in the work was inspired by the deep desire to understand the reasons for the disconnect I saw between the food system and the distancing of the very people who produced it". She declares that organics offers "the only future if the planet is to survive".

This experimentwas carried out with the objective of determining the energy and protein requirements of grazing Nellore steers. Twenty four Nellore steers (average 371 ± 14 kg of BW and 26 months old) were used. Four steers were slaughtered at the beginning of the experiment (reference group), serving as a reference for the subsequent study. The remaining 20 animals were weighed and distributed in a randomized complete block design with four levels of supplementation offers: 0.0 (mineral mixture - control), 0.3, 0.6 and 0.9% BW, with five replications. The supplements, based on ground corn, soybean meal and/or urea, were previously balanced to achieve an average daily gain of 350, 650 and 850g, respectively, for the different levels of supplementation...

Body composition and net and dietary macrominerals requirements of Nellore steers under grazing
Provedor de dados: 96
Autores: Almeida,Vitor Visintin Silva de; Queiroz,Augusto César de; Silva,Robério Rodrigues; Silva,Fabiano Ferreira da; Oliveira,Aline Cardoso; Santana Júnior,Hermógenes Almeida de.
This experiment was carried out with the objective of determining the macrominerals (Ca, P, Mg, K and Na) requirements of Nellore steers under grazing. Twenty four Nellore steers (371 ± 14 kg of BW and 26 mo old) were used. Four steers were slaughtered at the beginning of the experiment (reference group), serving as a reference in subsequent study. The remaining 20 animals were weighed and distributed into a completely randomized design with four supplementation levels offer: 0.0 (mineral mixture - control), 0.3, 0.6 and 0.9% of BW, with five replications. The supplements, based on ground corn, soybean meal and/or urea, were previously balanced to achieve an average daily gain of 350, 650 and 850g, respectively, for the different supplementation levels...

Body composition and net protein and energy requirements for weight gain of crossbred dairy cattle in grazing
Provedor de dados: 96
Autores: Andrade,Dulciene Karla Bezerra de; Véras,Antonia Sherlânea Chaves; Ferreira,Marcelo de Andrade; Santos,Mércia Virginia Ferreira dos; Melo,Wellington Samay de; Pereira,Kedes Paulo.
The body composition and net protein and energy requirements for weight gain of 5/8 Hostein-Zebu crossbred cattle raised in Brachiaria decumbens Spaft pasture were evaluated. In total, 16 bulls with 10 months of age and body weight (BW) of 180 ± 19.95 kg were used. The animals were kept with free access to pasture or with restricted grazing (from 6 to 10 h). Four animals were slaughtered at the beginning of the experimental period to estimate the empty body weight (EBW) and the initial body composition of the remaining animals. The other animals were slaughtered at the end of the 84-day trial period. The logarithm equations of the protein and energy body content were adjusted according to the logarithm of the empty body weight EBW. From these equations,...

Body size and extinction risk in Brazilian carnivores
Provedor de dados: 49
Autores: Forero-Medina,German; Vieira,Marcus Vinícius; Grelle,Carlos Eduardo de Viveiros; Almeida,Paulo Jose.
Because extinctions are not random across taxa, it is important for conservation biologists to identify the traits that make some species more vulnerable. Factors associated with vulnerability include small geographical ranges, low densities, high trophic level, "slow" life histories, body size, and tolerance to altered habitats. In this study we examined the relationship of body size, reproductive output, longevity, and extinction risk for carnivores occurring in Brazil. We used generalized linear models analyses on phylogenetically independent contrasts to test the effect of body size alone, and the combined effect of body size, litter size and longevity on extinction risk. Body size appeared in the two best models according to the selection criteria...

Body Weight Outcomes and Food Expenditures Among Older Europeans: A simultaneous equation approach
Provedor de dados: 31
Autores: Drichoutis,   Andreas C.; Lazaridis,   Panagiotis; Nayga,   Rodolfo M., Jr.
We analyze the inter-relationships between body weight outcomes and food expenditures among older Europeans using a simultaneous equation model. Several statistical tests were conducted to assess endogeneity of selected variables, the exogeneity, relevance, and validity of instruments used, and the identification of the model. Our results generally suggest, contrary to normative views, that food-away-from-home expenditure is negatively related to body mass index (BMI). BMI is negatively related to the percentage of food spent away from home.

Body weight-length relationships in giant otters (Pteronura brasiliensis) (Carnivora, Mustelidae)
Provedor de dados: 52
Autores: Rosas,Fernando César Weber; Rocha,Carla Soares da; Mattos,Gália Ely de; Lazzarini,Stella Maris.
Few giant otters (Pteronura brasiliensis) have been measured and weighed and its actual size is controversial in the literature. This study presents the weight-length relationship of Amazonian giant otters using 15 captive individuals. The maximum length and weight were 163cm and 22.5kg, and 162cm and 28.8kg, for the males and females, respectively. The weight-length relationships were not significantly different between the sexes (t = 0.658, d.f.=11, P&gt;0.05) and can be expressed by the equation: W=1.48x10-5 L2.81. Considering that some of the giant otters used in this study were old individuals (more than 10 years old), and that all the animals analyzed were healthy, it is possible to assume that the weight-length relationships obtained are probably a...

Bolivia : entre las encrucijadas del narcotráfico en la Región Andina
Provedor de dados: 122
Autores: Ruiz Labrador, Elena.
La llegada al poder de Evo Morales en Bolivia y de Hugo Chávez en Venezuela ha traído consigo cambios sustanciales en la relación de algunos países andinos con Estados Unidos. Los motivos recaen en que el discurso de ambos está plagado de ataques contra este país amparándose en la necesidad de tomar posiciones anti imperialistas y en recuperar la soberanía perdida por la intervención del gobierno estadounidense en los andes.  Es probable que una de las áreas que más influencia ha tenido en la relación entre Estados Unidos y los cinco países que forman la región andina, Venezuela, Bolivia, Ecuador, Perú y Colombia haya sido la de la lucha antinarcóticos.  Desde los años 80 en que Ronald Reagan declaró la guerra contra las drogas y la asumió como un problema...

Boosting smallholder production for food security: some approaches and evidence from studies in sub-Saharan Africa
Provedor de dados: 31
Autores: Matshe,   Innocent.
This paper uses the sustainable livelihoods framework to explore the contribution of smallholder production to food security in some sub-Saharan African countries and relates it to the South African case. Noting that many of the world’s hungry are smallholder farmers, it is clear that food insecurity is closely linked to the livelihood strategies of these farm households. As previous studies have shown, food insecurity is linked to livelihood assets, strong institutional support and a favourable external environment. In particular, the paper finds that food security depends on cereal output, budgetary support to agriculture, agricultural value added and poverty – all variables strongly linked to the sustainable livelihoods framework. Since most poor rural...

A incidência de hastes ocas em brócolis (Brassica oleracea L. var. italica Plenck) depende de vários fatores que afetam a absorção e o transporte de B, elemento responsável pelo aparecimento dessa desordem fisiológica. O trabalho avaliou os efeitos de quatro níveis de nitrogênio e dois níveis de boro e da interação entre eles na incidência de hastes ocas e na produção de brócolis. As doses de N (100, 150, 200 e 250 kg ha-1) foram divididas em quatro aplicações iguais aos 15, 30, 45 e 60 dias após o transplante. O boro (0, 4 e 8 kg ha-1) foi aplicado metade no plantio e a outra metade em cobertura aos 45 dias após o transplante. A massa média das inflorescências e a produção total foram diminuídas com a aplicação de B em função do crescimento mais lento das...

Boron extraction and vertical mobility in Paraná State oxisol, Brazil
Provedor de dados: 90
Autores: Oliveira Neto,Waldemar de; Muniz,Antonio Saraiva; Silva,Maria Anita Gonçalves da; Castro,Cesar de; Borkert,Clovis Manuel.
The deficiency or excess of micronutrients has been determined by analyses of soil and plant tissue. In Brazil, the lack of studies that would define and standardize extraction and determination methods, as well as lack of correlation and calibration studies, makes it difficult to establish limits of concentration classes for analysis interpretation and fertilizer recommendations for crops. A specific extractor for soil analysis is sometimes chosen due to the ease of use in the laboratory and not in view of its efficiency in determining a bioavailable nutrient. The objectives of this study were to: (a) evaluate B concentrations in the soil as related to the fertilizer rate, soil depth and extractor; (b) verify the nutrient movement in the soil profile; (c)...

Understanding the magnitude of B mobility in eucalyptus may help to select clones that are more efficient for B use and to design new practices of B fertilization. This study consisted of five experiments with three eucalyptus clones (129, 57 and 58) where the response to and mobility of B were evaluated. Results indicated that clone 129 was less sensitive to B deficiency than clones 68 and 57, apparently due to its ability to translocate B previously absorbed via root systems to younger tissues when B in solution became limiting. Translocation also occurred when B was applied as boric acid only once to a single mature leaf, resulting in higher B concentration in roots, stems and younger leaves. The growth of B-deficient plants was also recovere by a...

Bottom-up and top-down effects on algal community dynamics in an aridland river:  the Middle Rio Grande, New Mexico&amp;#xb;
Provedor de dados: 17
Autores: Ayesha S. Burdett; Rebecca J. Bixby.
Background/Question/Methods&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;In this study, we examined interactive effects of nutrient availability, river flow and food web structure on algal growth and species composition in the Middle Rio Grande, New Mexico. Algal community dynamics can be affected by both bottom-up and top-down factors. Algal production may be limited by low levels of nutrients or low light availability. Conversely, production is expected to increase when nutrient levels are high and light availability is not limited.  Top-down factors such as grazing by invertebrates can also alter periphyton growth and community composition. Generally, a reduction in grazers results in periphyton biomass increases and shifts in growth forms (to more upright...

Boty-II, a novel LTR retrotransposon in Botrytis cinerea B05.10 revealed by genomic sequence
Provedor de dados: 69
Autores: Zhao,Ming; Zhou,Jin yan; Li,Zhi dong; Song,Wei wei; Tan,You jiu; Tan,Hong.
Botrytis cinerea is a necrotrophic pathogen causing pre- and post-harvest diseases in at least 235 plant species. It manifests extraordinary genotype and phenotype variation. One of the causes of this variation is transposable elements. Two transposable elements have been discovered in this fungus, the retrotransposon (Boty), and the transposon (Flipper). In this work, two complete (Boty-II-76 and Boty-II-103) and two partial (Boty-II-95 and Boty-II-141) long terminal repeat (LTR) retrotransposons were identified by an in silico genomic sequence analysis. Boty-II-76 and Boty-II-103 contain 6439 bp nucleotides with a pair of LTRs at both ends, and an internal deduced pol gene encoding a polyprotein with reverse transcriptase and DDE integrase domains. They...

Boundary layer development and shear stresses measurements around an oyster table
Provedor de dados: 5
Autores: Kervella, Youen; Germain, Gregory; Gaurier, Benoit; Facq, Jean-valery; Cayocca, Florence; Lesueur, Patrick.
Oyster tables are artificial obstacles which are laid over muddy or sandy-muddy floors in intertidal areas. This study aims to show the current modifications related to the presence of the oyster table thanks to LDV measurement in a flume tank. Boundary layer development in different geometric configuration is underlined and suggests some important areas of velocity decrease and sediment transport modification. Shear stresses are also calculated near the bottom and around the table. The total shear stress in the water column exhibits an important increase when the flow passes through the oyster table, hence a flow energy decrease through dissipation. This study helps to understand the reasons for the increased sedimentation observed in some natural sites.

BOUNDARY ORGANIZATIONS: AN EFFICIENT STRUCTURE FOR MANAGING KNOWLEDGE IN DECISION-MAKING UNDER UNCERTAINTY
Provedor de dados: 31
Autores: Boissin,   Denis.
Modern environmental issues imply that decision-makers take into account opinions from experts of different spheres. Boundary organizations are institutions able to cross the gap between different areas of expertise and to act beyond the boundaries while remaining accountable to each side: by encouraging a flow of useful information, they permit an exchange to take place while maintaining the authority of each side, in order to provide a better knowledge and understanding of a situation characterized by uncertainty. Though never formally proved, this hypothesis is widely accepted based on the observation of existing boundary organizations. Through a multi-agent simulation, it is possible to assess their impact on the diffusion of opinions among experts....

Bovine coronavirus detection in a collection of diarrheic stool samples positive for group a bovine rotavirus
Provedor de dados: 52
Autores: Barry,Aline Fernandes; Alfieri,Alice Fernandes; Stipp,Danilo Tancler; Alfieri,Amauri Alcindo.
Neonatal diarrhea is an important cause of economic losses for cattle farmers. The main viral etiologies of enteric diseases are group A rotaviruses (GARV) and the bovine coronavirus (BCoV). Although both viruses infect calves of the same age, the occurrence of mixed infections is still under studied. The present study describes the co-infection of BCoV and GARV in stool samples. Forty-four diarrheic fecal samples from calves up to 60 days old that had previously tested positive for GARV by SS-PAGE were analyzed using semi-nested PCR for BCoV. A product with 251 bp of the BCoV nucleoprotein gene was amplified in 15.9% (7/44) of the samples, demonstrating that co-infection is not an unusual event. These results reinforce the need for testing for both GARV...

Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality and consumers' choice. The aim of this study was to determine allele and genotype frequencies of polymorphisms of the bovine genes, which encode leptin (LEP), thyroglobulin (TG) and diacylglycerol O-acyltransferase (DGAT1). A further objective was to establish the effects of these polymorphisms on meat characteristics. We genotyped 147 animals belonging to the Nelore (Bos indicus), Canchim (5/8 Bos taurus + 3/8 Bos indicus), Rubia Gallega X Nelore (1/2 Bos taurus + 1/2 Bos indicus), Brangus Three-way cross (9/16 Bos taurus + 7/16 Bos indicus) and Braunvieh Three-way cross (3/4 Bos taurus + 1/4 Bos indicus)...

Bovine Oocytes and Early Embryos Express mRNA Encoding Glycerol Kinase but Addition of Glycerol to the Culture Media Interferes with Oocyte Maturation
Provedor de dados: 19
Autores: OKAWARA, Sumika; HAMANO, Seizo; TETSUKA, Masafumi; 手塚, 雅文.
Glycerol plays multi-functional roles in cellular physiology. Other than forming the backbone molecule for glycerophospholipid and triglyceride (TG), glycerol acts as an energy substrate for glycolysis. Spermatozoa are known to utilize glycerol for energy production, but there are no reports of this in oocytes. In this study, the value of glycerol as an energy substrate for bovine oocyte maturation (Exp. 1) and the gene expression of glycerol kinase (GK), an enzyme crucial for cellular glycerol utilization, in bovine oocytes and early embryos (Exp. 2) were examined. In Exp. 1, in vitro maturation (IVM) was conducted using synthetic oviduct fluid supplemented with/without glucose (1.5 mM) and/or glycerol (1.0 mM), and maturation rate, degree of cumulus...

Currently, Brachiaria brizantha Stapf is the tropical grass with the largest cultivated area in Brazil, being responsible for a major part of the seed market and for the increase in animal production. There are several superior genotypes available in germplasm banks, collected from the African continent and in need of evaluation. The selection of these genotypes must be based on predicted genotype values of the individuals in function of being perennial plants and of unsexed propagation. The standard procedure for the prediction of genetic values is the individual BLUP (Best Linear Unbiased Predictor), using estimates of variance components achieved by the restricted maximum likelihood (REML) on an individual model. With the aim of selecting B. brizantha...

Autores: Martínez Chacón, M.L.; Winkler Prins, C.P.
After a short introduction on the lower Pennsylvanian (Bashkirian to lowermost Moscovian)Valdeteja Formation in its stratigraphical context, an overview of its brachiopod faunas is presented and their palaeoecological and palaeogeographic importance discussed. Two new genera of the Strophalosiidina, showing adaptations to a reef environment, are described. The genus Ovetina (type species O. truyolsi gen. et sp. nov.) is an aulostegid with a well developed ventral flange. Miroproductus (type species M. posadai gen. et sp. nov.) is an early richthofenioid, probably derived from an aulostegid such as Institina MUIR-WOOD &amp; COOPER, 1960.

Braga cigarra comb. nov. for Philostomella cigarra (Crustacea: Isopoda: Cymothoidae) with a redescription of the species based on specimens from Galeocharax kneri, a freshwater fish of Minas Gerais State, Brazil
Provedor de dados: 103
Autores: Thatcher,Vernon E.; Oliveira,Antonio A. N. de; Garcia,Adriana M.
Specimens of a cymothoid isopod from a freshwater fish of Minas Gerais State were studied. These were found to be morphologically comparable to Philostomella cigarra Szidat &amp;amp; Schubart, 1960, except for having multilaminate pleopods which is the distinguishing characteristic of the genus Braga Schiödte &amp;amp; Meinert, 1881. The first pleopod is bilaminate while the second is quadrilaminate. Pleopods three to five are trilaminate. It is herein proposed that the generic name Philostomella Szidat &amp;amp; Schubart, 1960, should be considered invalid and that the species P. cigarra should be transferred to Braga. Braga now contains eight species, including B. cigarra comb. nov., all from South American freshwater fishes. The principal difference...

Analyzing of sequences similarities is the first and most important method used to find out the function of unknown nucleotides. Searching of homologs should be done carefully not to loose any important ones. Having thousands of results from various long-read sequencing projects (ie. differentially expressed tags, genomic polymorphons or BAC ends), the by-hand ability to retrieve interesting (to our goal) similarities in hundreds of Blast results decreases rapidly. Decreasing the number of retrieved sequences by giving more stringency in e-value threshold or displaying less results could lead to false deductions. Functional genomics, proteomics and metabolomics could give us answers to the role of nucleotide sequences. It makes the need to annotate as much...

BrainGrab: Capturing Curator Expertise as Reusable Annotation Rules
Provedor de dados: 17
Autores: Daniel H. Haft; Malay K. Basu; Roland A. Richter.
Experienced biocurators can outperform automated systems on specific genes once they determine which pieces of evidence should drive annotation, and which annotations should be spread. The annotation logic may weigh both homology evidence (BLAST matches or HMM hits) and non-homology evidence (neighboring genes, metabolic context, taxonomic group). Unfortunately, the expertise developed to annotate each gene is short-lived, and is mostly lost if the logic driving the annotation is not captured. We report the development of BrainGrab, an interface added to the MANATEE manual annotation tool for prokaryotic genomes. The curator can specify evidence scenarios that should always lead to equivalent annotation for similar genes in similar contexts, and thus...

BRANDING REGIONAL IDENTITY AS A DRIVER FOR RURAL DEVELOPMENT
Provedor de dados: 31
Autores: Messely,   Lies; Dessein,   Joost; Lauwers,   Ludwig H.
Within the globalizing world, regions and their identities are subjected to great pressure. At present, places are engaged in a process of “territorial competition” in an integrated world economy. The identity of the region can be used as a starting point to brand a region and differentiate it from others. In the regional branding process, the region as a whole becomes a product or brand and offers a “basket” of regional products and services. This paper discusses the possibility of regional identity as a mobilizing force for rural development, by studying best practice examples of regional branding. Using the grounded theory approach, we conducted interviews in three case regions: West Cork (Ireland), Groene Woud (the Netherlands) and Pajottenland...

Brazilian greenhouse gas emissions: the importance of agriculture and livestock
Provedor de dados: 63
Autores: Cerri,Carlos Clemente; Maia,Stoecio Malta Ferreira; Galdos,Marcelo Valadares; Cerri,Carlos Eduardo Pellegrino; Feigl,Brigitte Josefine; Bernoux,Martial.
Data from the 1990-1994 period presented in the "Brazil's Initial National Communication" document indicated that the country is one of the top world greenhouse gas (GHG) emitters. A large majority of Brazil's GHG emissions come from deforestation mainly of the Amazon biome for agriculture and livestock land uses. This unique inventory is now out of date. Thus, the aims of this review were (i) to update estimates of the GHG emissions for the Brazilian territory, (ii) to estimate the sinks to provide calculations of the GHG net emissions for the 1990-2005 period, (iii) to calculate the actual and estimate shares of agricultural and livestock activities, and (iv) to discuss in light of the new figures and patterns the best mitigation options for Brazil....

Brazilian maize genotypes sensitivity to water deficit estimated through a simple crop yield model
Provedor de dados: 86
Autores: Andrioli,Kleber Gustavo; Sentelhas,Paulo Cesar.
The objective of this work was to determine the sensitivity of maize (Zea mays) genotypes to water deficit, using a simple agrometeorological crop yield model. Crop actual yield and agronomic data of 26 genotypes were obtained from the Maize National Assays carried out in ten locations, in four Brazilian states, from 1998 to 2006. Weather information for each experimental location and period were obtained from the closest weather station. Water deficit sensitivity index (Ky) was determined using the crop yield depletion model. Genotypes can be divided into two groups according to their resistance to water deficit. Normal resistance genotypes had Ky ranging from 0.4 to 0.5 in vegetative period, 1.4 to 1.5 in flowering, 0.3 to 0.6 in fruiting, and 0.1 to 0.3...

Brazilian species of Onychophora with notes on their taxonomy and distribution
Provedor de dados: 103
Autores: Sampaio-Costa,Cristiano; Chagas-Junior,Amazonas; Baptista,Renner L. C.
A revision of the currently known distribution of Onychophora (velvet worms) in Brazil is presented. Twenty-four morphospecies (half of them undescribed) belonging to four genera of the Peripatidae (Peripatus Guilding, 1826, Epiperipatus Clark, 1913, Macroperipatus Clark, 1913 and Oroperipatus Cockerell, 1908) are recorded. This high number of "unidentified" morphospecies is due to three major reasons: the poor quality of the characters used in species-level identification, the inadequate specimen conservation in ethanol, and, in most cases, the lack of additional specimens for analysis of intra- and inter-specific variation. The morphological characters currently used to separate Peripatidae species present a large degree of variation and may not be...

Brazil's Rising Agricultural Productivity and World Competitiveness
Provedor de dados: 31
Autores: Rada,   Nicholas E.; Buccola,   Steven T.; Fuglie,   Keith O.
Brazil now is the largest coffee, sugar, and fruit juice producer, second-largest soybean and beef producer, and third-largest corn and broiler producer.  It has overtaken the U.S. in poultry exports, nearly matches the U.S. in soybean exports, and dominates global trade in frozen orange juice.  To test and better understand these advances, we draw on decennial farm censuses to examine technical change and efficiency in Brazilian agriculture.  Our approach is to estimate a stochastic, multi-product, output distance frontier, using a translog functional form and data disaggregated to the micro-region (sub-state) level.  Using two consecutive decennial farm censuses, we combine state-level Fisher productivity-change indexes with state-level translog distance...

The recent rise in food prices has increased the concern about the choice of a healthy food basket, especially in the context of the discussion around the formulation of a National Food Policy for Scotland. This concern has brought back the interest in the price and expenditure demand systems as they provide information about consumers’ food decisions. The paper focuses on the consumption of brown and white bread, as they are the most typical ways of cereals use in the UK and nutritionists recommend the consumption of wholemeal or brown bread in contraposition to white bread as part of an appropriate diet due to its health benefits. This paper aims to answer whether changes in bread prices affect the quantity and composition of the Scottish demand for...

Plants of Capsicum annuum cv. Magali R, resistant to Pepper yellow mosaic virus (PepYMV), which showed severe yellow mosaic, leaf malformation and stunting were observed during the 2003/04 growing season in Lins, São Paulo State, Brazil. Potyvirus-like particles observed in leaf sap from infected plants under the electron microscope reacted with an antiserum against PepYMV in PTA-ELISA. In addition to C. annuum cv. Magali R, this potyvirus also infected systemically the resistant C. annuum cv. Rubia R. The nucleotide sequence of part of the CP gene of this potyvirus shared 96-98% identity with that of other PepYMV isolates. The partial nucleotide sequence of the 3' NTR showed 94-96% identity with that of PepYMV. These data indicate that this potyvirus is a...
