10 Jahre differenzierte Grundbodenbearbeitung im Ökologischen Landbau. Auswirkungen auf die Besiedlung mit Collembolen
Provedor de dados: 21
Autores: Bassemir, Ursula K.
During 10 years a crop rotation schedule consisting of different crops (green fallow; intercrop: winter wheat; peas; intercrop: winter rye; summer barley) was combined with three different tillage techniques (plough, inverting to 30 cm depth, intensive; two-layer plough, inverting to 15 cm depth and loosening to 30 cm depth, reduced inverting; layer cultivator, loosening to 30 cm depth, conservation tillage). First results show a significant effect of crop on springtails. There is no significant effect of tillage techniques, although there is a tendency in slightly increased population density of springtails by using plough and layer cultivator. Further detailed results will be reported elsewhere.

100 % organic ration works for organic table birds
Provedor de dados: 21
Autores: Woodward, Lawrence; O'Brien, Josie.
Poultry researcher Josie O’Brien and Lawrence Woodward present some results from a series of EFRC trials that are questioning the need for the conventional feed derogation in organic poultry production.  Currently the use of up to twenty percent of non-organic components is allowed in the feed ration of organically certified table birds.  Although this derogation is supposed to be removed in August 2005, there is mounting pressure to allow it to continue in some form. The derogation was introduced due to concerns that without it the bird’s nutritional needs could not be met by certified organic sources alone and therefore their health, welfare and growth would be compromised.  The primary concern relates to amino acid levels and in particular methionine....

2004 Cereals reveal an intriguing surprise: the performance of cereals on organic farms
Provedor de dados: 21
Autores: Wolfe, Martin; Hinchsliffe, Kay.
The great variability in the performance of cereals on organic farms that we have highlighted from past research trials has been confirmed in a new and more widely based trial. Participation from 20 producers gives the results a robust character and has enabled us to spot something we had not previously noted. EFRC researchers Prof Martin Wolfe AND Kay Hinchsliffe set out the results.    Introduction  EFRC is currently working on a Defra-funded project designed to use participatory research and development methodology, and is conducted on sites across the country with the participation of 20 farmers, seed producers and more than 10 researchers (EFRC, NIAB, Middlesex University, University of Kingston &amp; HDRA). The idea is to integrate the contributions...

2005 NORTH DAKOTA AGRICULTURAL OUTLOOK: REPRESENTATIVE FARMS, 2005-2014
Provedor de dados: 31
Autores: Swenson,   Andrew L.; Koo,   Won W.; Taylor,   Richard D.
Net farm income for all representative farms in 2014 is projected to be lower than in 2004.  Low-profit farms, which comprise 25% of the farms in the study, may not have financial resiliency to survive without off-farm income.  Costs are projected to increase faster than yields, which will pressure net farm income downward.  Cropland prices and cash rental rates are projected to increase slightly in all regions.  Debt-to-asset ratios for most farms will decrease slightly throughout the forecast period.  Debt-to-asset ratios for the low-profit and small-size farms are higher than those for large and high-profit farms.

2005 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS, 2004-2013
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2004-2013 using the Global Sugar Policy Simulation Model.  This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to improve slightly over the next nine years after the current over-supply is reduced.  World demand for sugar is expected to grow faster than world supply, resulting in Caribbean sugar prices gradually increasing from 8.40 cents/lb in 2004 to 8.70 cents/lb in 2013.  The U.S. wholesale price of sugar is projected to decrease from 26.15 cents/lb in 2004 to 24.89 cents/lb in 2013, if the United States maintains its sugar programs....

This report evaluates the U.S. and world wheat markets for the 2004-2013 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 improve for the next nine years.  World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties.  However, the higher price levels experienced in 2002 and 2003 due to weather conditions will not be maintained in the short term.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum...

20th century fluctuations in the abundance of siliceous microorganisms preserved in the sediments of the Puyuhuapi Channel (44° S), Chile
Provedor de dados: 97
Autores: REBOLLEDO,LORENA; LANGE,CARINA B.; FIGUEROA,DANTE; PANTOJA,SILVIO; MUÑOZ,PRÁXEDES; CASTRO,RODRIGO.
We present a 100-year reconstruction of siliceous export production from sediments of the Puyuhuapi Channel (44° S, 70° W) in the Chilean fjords. We use accumulation rates and concentrations of diatoms and silicoflagellates, organic carbon (Corg) and biogenic opal (SiOPAL) as proxies of export production, and fluctuations in the contribution of freshwater diatoms as proxies of rainfall in the hinterland and river runoff. Box core sediments collected at two sites within the Puyuhuapi Channel were analyzed: Station 35 (at the head of the fjord; 56 m water depth) and Station 40 (in the middle of the Channel; 270 m water depth). Surface sedimentation rates were 0.75 cm yr-1 at Station 35 and 0.25 cm yr-1 at Station 40. SiOPAL content averaged ~ 4 % at both...

É comum o clínico veterinário submeter animais à quimioterapia para controle de neoplasias e observar depressão medular, com presença de anemia, leucopenia e trombocitopenia como efeitos colaterais. Nesses casos, podem-se adotar duas condutas: supressão da quimioterapia e/ou utilização de estimulantes de medula óssea. Dentre os medicamentos estimulantes mais utilizados, podemos citar o decanoato de nandrolona (Deca-durabolin®), cuja eficácia para os animais domésticos é pouco estudada, com poucos relatos na literatura nacional e internacional. Este trabalho visou estudar a ação do decanoato de nandrolona (DN), na dose de 1,5mg/kg, por via intramuscular, como estimulante de medula óssea em ratos (Rattus rattus) com supressão medular induzida pelo sulfato de...

A BALATON VÍZGYŰJTŐJÉN FOLYÓ MEZŐGAZADSÁGI TERMELÉS HATÁSA A TÓ KÖRNYEZETI ÁLLAPOTÁRA
Provedor de dados: 31
Autores: Marton,   Istvan.
A Balaton vízminőségének, a tó állapotának romlása több tényezőre visszave-zethető, hosszú folyamat eredménye. Az egyes tényezők szerepének meghatáro-zása a rendszeres és teljes körű, minden szennyező faktorra kiterjedő mérések hiánya miatt napjainkban is gondot okoz, részben becslésen alapul. Mégis vissza-térő kérdés, hogy a leromlásért melyik ágazat az első számú felelős. A 80-as évek elején a feladatok meghatározásakor a tó vizének tápanyag feldúsulásáért a me-zőgazdaságot kiáltották ki fő felelősnek. Ugyanakkor szakértői vizsgálatok egy-értelműen bizonyították, hogy a Balatonba kerülő hatóanyag maximum 3-5%-a lehet műtrágya eredetű, ami önmagában a vízminőség gyorsütemű romlását nem idézhette elő. Akik kizárólag a mezőgazdaságot okolták a Balaton...

A Bayesian Examination of Anchoring Bias and Cheap Talks in Constructed Markets
Provedor de dados: 31
Autores: Aadland,   David; Caplan,   Arthur J.
We present a theoretical framework for understanding the relationship between anchoring bias, hypothetical bias, and cheap talk in constructed markets.  In our theory, interviewers provide agents with signals such as cheap talk and bid values while eliciting the value for nonmarket goods.  In response to these signals, agents revise their prior distributions over the value of the good.  Previous empirical studies have failed to account for the interaction between cheap talk and anchoring during this updating process, leading researchers to incorrectly assess the effects of cheap talk in reducing hypothetical bias.  In particular, we predict that cheap talk will appear to be more effective for relatively large bids.  We test our theory in an experimental...

A Bilateral Comparison of Fruit and Vegetable Consumption: United States and Canada
Provedor de dados: 31
Autores: Richards,   Timothy J.; Patterson,   Paul M.
Many public programs promote diets rich in fruits and vegetables based on evidence of the derived health benefits. Still, produce consumption in the United States lags behind other nations, even its most culturally similar neighbor--Canada. This study uses a structural latent variable model to test the role played by quality and health information in explaining observed differences in produce consumption. The Alchian-Allen effect predicts that higher quality, higher absolute margin produce will be exported, suggesting quality may be an important demand factor in importing nations such as Canada. The results show that dietary health information is significant in expanding demands. Quality also promotes fruit consumption in Canada.

A Bioeconomic Model of the Soybean Aphid Treatment Decision in Soybeans
Provedor de dados: 31
Autores: Olson,   Kent D.; Badibanga,   Thaddee Mutumba.
Since its first detection in the North Central region in July 2000, the soybean aphid (Aphis glycines Matsamura) has caused considerable loss in soybean (Glycine max L.) yield, bean quality, and producer income.  Discovered first in Wisconsin and then in adjoining states, it is currently distributed in 21 US states and parts of Canada. In 2003, over 42 million acres of soybean in the North Central US were infested and over 7 million acres were treated with insecticides to control soybean aphid (Landis et al. 2003). Populations exceeding 24,000 aphids per plant and 40% losses in seed yield have been reported (DiFonzo &amp; Hines 2002). Even prior to the outbreak of 2003, the Soybean Strategic Pest Management Plan identified soybean aphid as one of the key...

A Brief Summary of U.S. Farm Program Provisions
Provedor de dados: 31
Autores: Richardson,   James W.; Anderson,   David P.; Outlaw,   Joe L.; Campiche,   Jody L.
This publication began as a need for a short summary of farm programs and farm bills for two agricultural economics courses focusing on agricultural policy -- ag. economics 429, and ag. economics 614. Over time, it became clear that many students taking these courses had less and less background in agriculture and less (even cursory) knowledge of policies than those of the recent past. After this list was developed, a number of other professional agricultural economists found copies and began to use it, hence its publication in a more structured form. The list of Farm Program Provisions is not all-inclusive. It certainly does not contain all the laws and provisions that have affected agriculture over the years. However, it is an easy reference to farm...

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

A case of homonymy in fossil verrucid barnacles: Verruca withersi (Crustacea, Thoracica)
Provedor de dados: 16
Autores: Jagt, J.W.M.; Buckeridge, J.S.
For fossil verrucid barnacles, the name Verruca withersi appears to have been used twice; Schram &amp; Newman described material from the Albian-Cenomanian (Cretaceous) of Colombia, while Kruizinga had previously recorded a new species from the Pleistocene(?) or perhaps younger strata of Sumba (Indonesia). We do not consider V. withersi Schram &amp; Newman to be a cirripede, therefore no replacement name is needed for this junior synonym. Verruca withersi Kruizinga is a valid species related to the extant V. cookei.

A Case Study of China's Commercial Pork Value Chain

Autores: Fabiosa,   Jacinto F.; Hu,   Dinghuan; Fang,   Cheng.
In China, with the cost of improved technology rising, surplus labor shrinking, and demand for food quality and safety increasing, it will be just a matter of time before the country’'s hog production sector will be commercialized like that of developed countries. However, even if China'’s cost of production converges to international levels, as shown in this case study, China may continue to retain some competitive advantage because of the labor-intensive nature of the marketing services involved in hog processing and meat distribution. The supply of variety meats offers the most promising market opportunity for foreign suppliers in China. The market may open further if the tariff rate for variety meats is reduced from 20% and harmonized with the pork...

A combined microsatellite multiplexing and boiling DNA extraction method for high-throughput parentage analyses in the Pacific oyster (Crassostrea gigas)
Provedor de dados: 5
Autores: Taris, Nicolas; Baron, S; Sharbel, Tim; Sauvage, Christopher; Boudry, Pierre.
The analysis of parentage using microsatellite markers is of increasing importance, notably in aquaculture genetic research where communal rearing of mixed families can be used to reduce unwanted environmental variance. We present here an optimization of parental genotype assessment for larvae or adults of the Pacific oyster, Crassostrea gigas, using a multiplex system of three microsatellite loci. In conjunction with a simple DNA extraction protocol, this method enables high throughput analyses of parentage in C. gigas. Using this method, we successfully determined the parentage of 93% (1224 out of 1318) of the progeny in a factorial cross between 3 females and 10 males. The inability to genotype the remaining 7% was due to DNA degradation of larvae...

A comparison of fitness between horses with different exercise history

Autores: Barker,   Anna B.E.; Warren-Smith,   A.K.
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from...

A Comparison of Risk and Return Characteristics of Efficient Crop Portfolios for the Brown Soil Zones Saskatchewan and Mecklenburg, Germany
Provedor de dados: 31
Autores: Schoney,   Richard A.; Moeller,   Christof.
Two efficient farms are constructed for the brown soils of Saskatchewan, Canada and for Mecklenburg, Germany based on producer panels. Both farms feature highly integrated cropping systems which take advantage of cropping synergies. However, farm risk is inherently different between the two because differences in 1) climate that gives rise to very different yield risk and cost structure, and 2) EU programs which offer fixed cash payments and stable sugar beet prices. As expected, risk is much higher for the Saskatchewan case farm - it has a chance of a negative cash flow of approximately one year in five. In sharp contrast, the Mecklenburg has very little chance of generating a negative cash flow. Hence, it is easy to understand why crop insurance and...

A comparison of soil properties under organic and conventional farming in Australia
Provedor de dados: 21
Autores: Nachimuthu, Gunasekhar; Kristiansen, Paul; Lockwood, Peter; Guppy, Chris.
Organic farming is an alternative to conventional farming for providing sustainable crops with high export demand. This review analyses research findings on organic farming in Australia, with an emphasis on soil health. Several reports have indicated that organic farm management generally improves soil physical properties in Australia and elsewhere. Although low nitrogen (N) availability can constrain yields, organic farmers can improve N supply through legume green manures. Plant available phosphorus (P) is a more serious limiting factor in organic farming, particularly in Australia with naturally low P levels. Phosphorus is less easily replaced in the soil than N, and there is a need for alternate sources of organic-certified P and methods to enhance P...

Autores: Wolf,   Marianne McGarry; Carpenter,   Scott; Qenani-Petrela,   Eivis.
This research shows that the wine market in the California is segmented by age. The wine-consumption behavior of the California wine consumer differs between the Generation X consumer and those in Generation Y and Baby Boomers. There are differences in demographics, purchasing attitudes, and purchasing behaviors among wine consumers from different generations. The findings from this research demonstrate that it is increasingly important to develop marketing strategies that are segmented for the target wine consumer. Generation Y are young wine consumers who are especially important for the industry because they offer an opportunity for growth–these younger generations are developing tastes now that are likely to last as they age.

This paper describes a comparison on farmers’ participation in farmers’ organisations and attempts to explain why they prefer to carry out production and marketing activities by themselves. It also examines the implications of the findings for rural extension and related services. A total of 122 interviews were conducted with different categories of farmers and with the extension workers. The comparative analysis of two case studies (Cruz Alta and Pantano) showed that socio-economic characteristics were not very significant in determining the level of farmers’ participation in farmers’ organizations in Minas Gerais. The ability of managers emerged as one of the most important factors in the success or failure of farmers’ organizations. The presence of...

A complementary method for production of tetraploid Crassostrea gigas using crosses between diploids and tetraploids with cytochalasin B treatments
Provedor de dados: 5
Autores: Mccombie, Helen; Ledu, Christophe; Phelipot, Pascal; Lapegue, Sylvie; Boudry, Pierre; Gerard, Andre.
We present a new method to produce tetraploid Crassostrea gigas by cytochalasin B inhibition of polar body 2 expulsion in diploid females crossed with tetraploid males. This offers a means of direct introgression of genetic characters from selected diploid to tetraploid lines, avoiding a triploid step. Offspring larval ploidy shifted over time and depended on size, with tetraploids more frequent among the smaller larvae and triploids among the large. Viable tetraploids were found at 4 and 6 months, indicating the technique was successful. The possibility that gynogenesis occurred was tested by microsatellite analysis to confirm the presence of paternally inherited alleles. These were present in all animals of the 2n x 4n + CB (female first) cross. However,...

A Computable General Equilibrium (CGE) Analysis of the Impact of an Oil Price Increase in South Africa
Provedor de dados: 31
Autores: McDonald,   Scott; van Schoor,   Melt.
Following recent international oil price increases, there has been considerable interest in how this external factor can affect the South African economy. This paper reports results from a computable general equilibrium (CGE) analysis of an increase (up to 30 per cent) in international oil prices. Background information is provided, which puts the magnitude of the price variations in historical context. We describe the procedure used to adjust the social accounting matrix (SAM), which is used to calibrate the model, to account explicitly for crude oil. Then, the effects of the crude oil price increase are traced through the economy, from markets, industries through to factors, households and the government. Predictably, the shock hurts the economy: a 20...

A connection between extracellular matrix and hormonal signals during the development of the human fetal adrenal gland
Provedor de dados: 56
Autores: Chamoux,E.; Otis,M.; Gallo-Payet,N.
The human adrenal cortex, involved in adaptive responses to stress, body homeostasis and secondary sexual characters, emerges from a tightly regulated development of a zone-specific secretion pattern during fetal life. Its development during fetal life is critical for the well being of pregnancy, the initiation of delivery, and even for an adequate adaptation to extra-uterine life. As early as from the sixth week of pregnancy, the fetal adrenal gland is characterized by a highly proliferative zone at the periphery, a concentric migration accompanied by cell differentiation (cortisol secretion) and apoptosis in the central androgen-secreting fetal zone. After birth, a strong reorganization occurs in the adrenal gland so that it better fulfills the newborn's...

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

The study presents an analysis of the coordination between the cassava's producers and the cassava's processors industry located in the west of State of Parana (Brazil). In a few years this chain became dynamics because of many factors, such as the institutional that is the most important one. In the last years it was verified a large volatility in cassava's production and price, that compromised the chain performance, mainly the cassava's starch modified production and price, which has high aggregate value. One of this oscillations cause, among other reasons was the lack of coordination between agents. To find evidences and solutions to the studies answers, the new institutional economy approach was studied. Three cassava's starch industries were analyzed...

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

The point of interest in this work is the dynamics of the small property through a filière analysis, identifying the internal and external relationships by the aggregation of value in each chain, besides calculating its contribution to the total value aggregation. Seeking to obtaining results, a case study was carried out and an input-product matrix was structured, using production values of a small property (12 ha). As a result, the property was found to be inserted in three filières (soy, milk and swine production), demonstrating the characteristic change of self-sufficiency for the integration in production chains. In the value aggregation (of total production) originating from the property (R$ 3.044.570), resulting in a final product of R$ 1.278.925,...

A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice
Provedor de dados: 31
Autores: Annou,   Mamane Malam; Wailes,   Eric J.; Thomsen,   Michael R.
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production.  Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty.  The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans.  The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

This paper presents an integrated ecological and economic model of aquatic plant species invasions in which resource users are the primary vector of species colonization. A random utility model of boater behavior is combined with ecological information about the invader and the landscape to form a dynamic principal-agent model in which the principal is a manager concerned with the interseasonal spread of invasive species across lakes, and agents are recreational boaters making a series of intraseasonal trip decisions to maximize random utility during the course of the season. Agent behavior is sensitive to both the degradation of environmental quality on colonized lakes and the actions taken by resource managers to control the spread of the invasive...

Os anestésicos são importantes na piscicultura para reduzir o estresse e a mortalidade no manejo. Este trabalho tem como objetivo determinar a eficácia do mentol para tambaqui durante o manejo. Na primeira série de testes, foi examinado o efeito da concentração de anestésico sobre indução à anestesia e o estresse de tambaqui. Na segunda série de testes, foi avaliada a recuperação dos peixes após a exposição a uma concentração de 150 mg/L de mentol por diferentes tempos. Na terceira série, foi avaliada se a melhor concentração encontrada para juvenil (150 mg/L) também era adequada para peixes maiores. A melhor concentração para uma anestesia cirúrgica foi 150 mg/L, pois o tempo de indução é rápido, porém a recuperação é significativamente mais demorada do...

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

A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea
Provedor de dados: 74
Autores: Dornelas,Marcelo Carnier; Rodriguez,Adriana Pinheiro Martinelli.
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene has a large C-terminal region of high similarity to angiosperm FLO/LFY orthologs and shorter regions of local similarity. In contrast to angiosperms, conifers have two divergent genes resembling LFY. Gymnosperm FLO/LFY proteins constitute a separate clade, that can be divided into two divergent groups. Phylogenetic analysis of deduced protein sequences has shown that PcLFY belongs to the LFY-like clade....

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

A Generic  Four-step Methodology For Institutional Analysis
Provedor de dados: 31
Autores: Herrera,   Paul A.; Van Huylenbroeck,   Guido; Espinel,   Ramon L.
The central hypothesis of this paper is that there may be situations in which the traditional approach to institutional analysis is of limited applicability. Such an approach, which has been called 'comparative institutional analysis', consists of comparing institutional environments and institutional arrangements in terms of specific economic or other efficiency criteria to see which one performs better. However, because of limitations to accurately predict the future performance of alternative institutional settings, comparisons are not always possible. Furthermore, in most cases the only information available is the performance of the current institutional setting. To account for this methodological deficiency, a generic methodology for institutional...

A geomagnetic paleointensity stack between 0.8 and 3.0 Ma from equatorial Pacific sediment cores
Provedor de dados: 5
Autores: Yamazaki, T; Oda, H.
We have conducted a paleomagnetic study of six sediment cores taken from the equatorial Pacific, three from the West Caroline Basin and three from the Manihiki Plateau, in order to make a relative paleointensity stack during the Matuyama and late Gauss Chrons. The age of the bottom of the cores ranges from 1.2 to 3.0 Ma. The sediments show little downcore changes in the proxies of magnetic grain size and mineralogy and are hence suitable for estimating relative paleointensity. The age of the cores is controlled by correlating variations in magnetic concentration ( magnetic susceptibility and/or anhysteretic remanent magnetization (ARM)) to target oxygen-isotope (delta(18)O) curves. All cores from the Manihiki Plateau show an upward decrease of the natural...

A GIS-based inventory of sediment pollution for watershed restoration planning
Provedor de dados: 31
Autores: Logan,   Joanne; Walker,   Forbes R.; Jolly,   Brooke A.; Foster,   Tiffany.
Under the Clean Water Act, U.S. states are required to establish water quality standards, list impaired waterbodies and create Total Maximum Daily Loads (TMDL) for impaired waters. Sediment contributes greatly to the water impairment in Tennessee, with agriculture often cited as the primary source. The watershed (catchment) in our study, Pond Creek, is listed as impaired for sediment and will require a TMDL and watershed restoration plan in the near future. The Tennessee Valley Authority (TVA) has developed an Integrated Pollutant Source Identification tool, consisting of aerial photographs, GIS database, and set of analysis spreadsheets to help plan watershed restoration efforts. We used this tool to assess sediment delivery from pastures, soil loss from...

Autores: Deblitz,   Claus; Hemme,   Torsten; Isermeyer,   Folkhard; Plessmann,   Frank.
Before IFCN was founded, existing farm-level data sets for international comparisons - if there were any - were not comparable. Differences from country to country regarding methodology applied, extent of data sets (physical and financial figures), and availability of up-to-date figures caused the incomparability. The IFCN is a world-wide association of agricultural scientists, advisors and farmers. Within the framework of this co-operation, farms and agricultural production systems are defined that are typical for their regions. Their economic situation is analysed, and the farms can be projected into the future. At present, the network, which is coordinated by the IFCN-centre in Braunschweig, Germany, operates for three branches: dairy (&gt; 30...

A Hedonic Analysis of Sheep and Goat Prices in a Changing Environment: The Role of Consumers and Implications for Management
Provedor de dados: 31
Autores: Singh-Knights,   Doolarie; Smith,   Dennis K.; Knights,   Marlon.
This paper examines whether buyers of live lambs and goats in the Northeast region have systematic preferences for specific live product attributes (age, weight, market class, sales lot size, market location and timing of sale) and whether they pay significantly different prices for these attributes consistent with their preferences.  Non-linear hedonic models are estimated using auction price and quality data for live lambs and goats in specific Northeast markets.  The results indicate that both lamb and goat buyers have systematic preferences for specific weight, market class and timing of sale, and that these preferences are implicitly reflected in prices offered in traditional auction markets.  Producers can capitalize on price differences based on...

A Hedonic Perspective to Estimating a Marginal Value Function for a Subsistence Crop
Provedor de dados: 31
Autores: Edmeades,   Svetlana.
A hedonic price model is used to estimate the marginal value function for output characteristics of a subsistence crop in a developing economy.  Within the framework of the agricultural household, with non-separable consumption and production decisions, prices reflect the implicit marginal valuation of both consumption and production attributes jointly.  Variety-specific crop product farm-gate prices are used in the hedonic analysis.  The findings provide guidance for future crop improvement efforts, while revealing those attributes most likely to capture premiums at the market place.  Implicit premiums for attribute scarcity are also revealed.  Improvements in infrastructure could partially reduce the implicit costs of transportation, leading to higher...

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

A histological study of microsporogenesis in Tarenna gracilipes (Rubiaceae)
Provedor de dados: 16
Autores: Vinckier, S.; Smets, E.
We studied the microsporogenesis in Tarenna gracilipes (Hayata) Ohwi, with special attention to the mode of exine deposition and tapetum development. We based this research on light (LM), scanning electron (SEM) and transmission electron microscopic (TEM) observations of developing anthers of T. gracilipes, from the microspore mother cell stage towards anther dehiscence. Evidence is supplied that the microsporogenesis in T. gracilipes can be considered as simultaneous. Columellae, foot layer and tectum develop in a fibrillar matrix. Similar with earlier studies in Rubiaceae species, a single white line formed near the plasmalemma in the extra-apertural region. The developing endexine dilated into several white line centered lamellae at the apertures. An...

The ontogenetic development of the gut and accessory organs in large yellow croaker Pseudosciaena crocea was investigated using light microscopy from hatching up to the juvenile stage (40 days post hatch, dph). At 3 dph (mean +/- S.D., 4.1 +/- 0.1 mm total length, L-T), coinciding with the buccopharynx opening, larvae started to feed exogenously, and the gut consisted of a well-developed buccopharynx, a partially-differentiated oesophagus and an intestine divided in three regions (anterior intestine, intermediate intestine and rectum). Yolk reserves were not completely depleted at the onset of exogenous feeding, and a period of mixed nutrition was observed up to 6 dph (4.3 +/- 0.1 mm L-T) when yolk was definitively exhausted.

The aim of this paper was to analyze the relative importance of the steel industry to the state of Espírito Santo, Brazil. The 1990 and 1999 Brazilian input-output matrices and Brazil’s regional accounts - state of Espírito Santo were used to build input-output matrices (1990 and 1999) to this state. Increases in final demand were simulated to analyze the effects on the production of each sector as well as on employment creation in this state. Backward and forward linkage indexes were also computed to twelve sectors with the same purpose. The results show that the steel industry is very important to the capixaba economy especially due to the high multiplier effects in response to increases in final demand. The results show also that the relative importance...

A JAPÁN GAZDASÁG NÉHÁNY JELLEGZETESSÉGE A XXI. SZÁZAD FORDULÓJÁN
Provedor de dados: 31
Autores: Tompe,   Ferenc.
Japán és a Távol-Kelet évtizedeken keresztül a világ egyéb térségeinek csodá-latát vívta ki elsősorban az átlagot meghaladó, gyors gazdasági növekedésével. Az 1990-es években a korábbi „keleti motor”-ként tekintett Japán gazdasága kü-lönleges helyzetbe került: a növekedés nagy mértékben lecsökkent, sőt hosszú időn keresztül alapvetően stagnált, az általánosan jellemző inflációt defláció váltotta fel. Ezek a jelenségek újból felkeltették a szakemberek érdeklődését a japán gazdaság iránt, egyfelől az előállt helyzet okainak feltárására, másfelől a megol-dások keresésére. A japán gazdaság megújulásának feltételeit döntően azok a té-nyezők határozzák meg, amelyek az elmúlt tíz évben a gyengélkedés okaiként je-lölhetők meg, mint pl. a hosszú ideig tartó...

Autores: Letenyei,   Krisztina.
A kávé kereskedelme a nemzetközi tőzsdéken folyik. Amikor a kínálat meg-haladja a keresletet, túlkínálat van. Ekkor alacsony a kávé ára, a túltermelési válság jelei mutatkoznak: elégetik a kávét. A kistermelők a tönk szélére kerül-nek. Ebben az időszakban a termelők kiirtják, illetve elhanyagolják a kávécser-jéket. A kávéexportáló országok csökkentik a termelést, az exportot is visszafog-ják, a raktárkészlet növekszik. Az elmaradt invesztíció és a rossz időjárási kö-rülmények hatására a kínálat csökken, majd a kereslet meghaladja a kínálatot, ami még ellensúlyozható a raktárkészletek piacra dobásával. Mivel a kávécser-jék csak öt év után fordulnak termőre, a kereslet tartósan meghaladja a kínála-tot. Ekkor a kávéárak a magasba szöknek. Ebben az időszakban...

A növénynemesítés fokozatosan romló működési körülményei, a hatékony marketing és a vetőmagkereskedelem hiányosságai, a külföldi fajták nyomása következtében több növényfajban a hazai nemesítés jelentősége csökkent az utóbbi 20 évben, sőt néhány növényfaj nemesítése Magyarországon meg is szűnt. A Kompolton folyó őszi árpa nemesítés eredményesen állt helyt a külföldi fajtaelőállítók nyomásának. Fajtáink kiváló termőképessége mellett, kiemelkedő télállósággal, igen jó szárszilárdsággal, megbízható állóképességgel, összességé-ben kiváló alkalmazkodóképességgel rendelkeznek.

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

A KÜLFÖLDI TŐKE SZEREPE ÉS A GAZDÁLKODÁS EREDMÉNYESSÉ-GÉRE GYAKOROLT HATÁSA AZ ÉLELMISZERIPARBAN
Provedor de dados: 31
Autores: Hodina,   Peter; Lamfalusi,   Ibolya.
A kilencvenes évtized első éveiben a külföldi tőkebefektetés egyik kiemelt cél-pontja az élelmiszeripar volt. A rendkívül gyors vállalat-felvásárlás és a megva-lósított tőkeemelés hatására 1993-ban a (vizsgált) élelmiszeripar összes jegyzett tőkéjének már 43 százaléka volt külföldi tulajdonban. Ez a részesedés 2000-re meghaladta a 60 százalékot. A dinamikusan növekvő tőkebefektetési tendencia 2000 után megtört, s azóta minden évben, kisebb-nagyobb mértékben mind a jegyzett tőke, mind pedig a külföldi tőke csökken az élelmiszeriparban.  A 2000. évet megelőző időszakban az élelmiszeriparban jelentkező többletki-bocsátás teljes egészében a külföldi tőkét is működtető vállalkozásokhoz kapcso-lódott.

A Laboratory Investigation of Compliance Behavior under Tradable Emissions Rights: Implications for Targeted Enforcement
Provedor de dados: 31
Autores: Murphy,   James J.; Stranlund,   John K.
This paper uses laboratory experiments to test the theoretical observations that both the violations of competitive risk-neutral firms and the marginal effectiveness of increased enforcement across firms are independent of differences in their abatement costs and their initial allocations of permits. This conclusion has important implications for enforcing emissions trading programs because it suggests that regulators have no justification for targeting their enforcement effort based on firm-level characteristics. Consistent with the theory, we find that subjects' violations were independent of parametric differences in their abatement costs. However, those subjects that were predicted to buy permits tended to have higher violation levels than those who...

A Latent-Variable Approach to Modelling Multiple and Resurgent Meat Scares in Italy
Provedor de dados: 31
Autores: Mazzocchi,   Mario; Lobb,   Alexandra E.
This paper aims to measure the time pattern of multiple and resurgent food scares and their direct and cross-product impacts on consumer response. The Almost Ideal Demand System (AIDS) is augmented by a flexible stochastic framework which has no need for additional explanatory variables such as a media index. Italian aggregate household data on meat demand is used to assess the time-varying impact of a resurgent BSE crisis (1996 and 2000) and the 1999 Dioxin crisis. The impact of the first BSE crisis on preferences seems to be reabsorbed after a few months. The second wave of the scare at the end of 2000 had a much stronger effect on preferences and the positive shift in chicken demand continued to persist after the onset of the crisis. Empirical results...

A legume genomics resource: The Chickpea Root Expressed Sequence Tag Database
Provedor de dados: 69
Autores: Jayashree,B; Buhariwalla,Hutokshi K; Shinde,Sanjeev; Crouch,Jonathan H.
Chickpea, a lesser-studied grain legume, is being investigated due to its taxonomic proximity with the model legume genome Medicago truncatula and its ability to endure and grow in relatively low soil water contents making it a model legume crop for the study of agronomic response to drought stress. Public databases currently contain very few sequences from chickpea associated with expression in root tissues. However, root traits are likely to be one of the most important components of drought tolerance in chickpea. Thus, we have generated a set of over 2800 chickpea expressed sequence tags (ESTs) from a library constructed after subtractive suppressive hybridization (SSH) of root tissue from two closely related chickpea genotypes possessing different...

A long term study of bonamiosis in Quiberon bay, France
Provedor de dados: 5
Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Berthe, Franck.
Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the...

A Lux-like Quorum Sensing System in the Extreme Acidophile Acidithiobacillus ferrooxidans
Provedor de dados: 48
Autores: RIVAS,MARIELLA; SEEGER,MICHAEL; HOLMES,DAVID S; JEDLICKI,EUGENIA.
The genome of the acidophilic, proteobacterium Acidithiobacillus ferrooxidans, contains linked but divergently oriented genes, termed afeI and afeR, whose predicted protein products are significantly similar to the LuxI and LuxR families of proteins. A possible promoter and Lux box are predicted upstream of afeI. A cloned copy of afeI, expressed in E. coli, encodes an enzyme that catalyzes the production of a diffusible compound identified by gas chromatography and mass spectrometry as an unsubstituted N-acyl homoserine lactone (AHL) of chain length C14. This AHL can be detected by a reporter strain of Sinorhizobium meliloti Rm41 suggesting that it is biologically active. The reporter strain also responds to extracts of the supernatant of A. ferrooxidans...

A kivitel zömét jelentő fehér asztali, táj hordós kategória megnyilvánuló komparatív előnye egyáltalán nem szerencsés az ágazat szempontjából, mivel az alacsony hozzáadott értéket adó hordós bor magas export részarányát sejteti, holott éppen a magas hozzáadott értéket generáló palackos borok esetében lenne ez kedvező az ágazat számára.

A tanulmány vizsgálja az agrárgazdaság 2004. évi jövedelmeinek alakulását, illetve azt, hogy ebben milyen szerepet játszottak az EU-csatlakozás mérlegének pozitív és negatív serpenyőjébe helyezhető tényezők. Az előbbiek sorában megemlíthetők a következők: a támogatási keretek növekedése, új pályázati lehetőségek, a spontán piaci ingadozások mérséklése, a várhatóan állandóbb szabályozási környezet, valamint a nagyobb termelői jövedelmek. A negatívumok sorában kiemelhetők: az intézményrendszer felkészületlenségéből eredő támogatás-kifizetési problémák s az...

A MAGYAR TEJTERMELÉS TŐKE TERMELÉKENYSÉGÉNEK PARCIÁLIS ELEMZÉSE

Autores: Geszti,   Szilard; Borbely,   Csaba.
A tőkeértékelés egyik lehetséges, de nem az egyetlen módja a tőketermelé-kenység vizsgálata. A tőke fogalmának összetettségéből adódóan – a termelési tényezők közül – a tőke termelékenységének a meghatározása és nemzetközi ösz-szehasonlítása a legbonyolultabb folyamat. Ennek ellenére az EDF módszertana megteremti a lehetőséget a tőketermelékenység egy speciális (kg FCM tej/1000 euró) értelmezésére. A tőketermelékenység, mint mutató nemzetközileg összeha-sonlítható, de részletes elemzés nélkül egzakt következtetés egy adott telep tőke-gazdálkodásáról nem vonható le. Ebből következően a termelékenység elemzését ki kellett egészíteni a tőke-költség, és a tőketényezők termelékenységének az elemzésével, amely számos információt nyújtott a telep...

A MAGYARORSZÁGI TEJPIAC VÁRHATÓ ALAKULÁSA
Provedor de dados: 31
Autores: Vago,   Szabolcs.
Az EU csatlakozás drasztikus hatással volt a hazai tejszektorra, ilyen környe-zetben különösen fontos, hogy a jövőbeni tendenciákról megbízható információk álljanak rendelkezésre. E cikk keretében a hazai, az uniós és a világpiaci helyzet áttekintését, valamint a rendelkezésre álló prognózisok alapján a magyarországi tejpiac várható alakulását mutatom be. Az erősödő kereslet következtében a tejtermékek világpiaci árának emelke-dése valószínűsíthető. A legnagyobb áremelkedés a sajtnál és vajnál várható, a tejporok ára kisebb mértékben nő. Az OECD prognózisa szerint a világtermelés 2013-ig jelentősen emelkedik, az EU-25 termelése pedig stagnál. Elsősorban az intervenciós árak csökkentése miatt az Európai Unióban a prognózisok szerint a tej piaci ára 15-20...

A male-sterile mutation in soybean (Glycine max) affecting chromosome arrangement in metaphase plate and cytokinesis
Provedor de dados: 47
Autores: Pires Bione,Nilton Cesar; Suely Pagliarini,Maria; Alves de Almeida,Leones.
A spontaneous male-sterile, female-fertile mutation affecting bivalent arrangement at the metaphase plate and cytokinesis was detected in line BR98-197 of the soybean breeding program developed by Embrapa - National Soybean Research Centre. Untill diakinesis, meiosis was normal with chromosome pairing as bivalents. From this phase, in several meiocytes, bivalents were not able to organize a single metaphase plate and remained scattered in the cytoplasm in a few or several groups. In these meiocytes, chromosomes segregated in both divisions giving rise to several micronuclei. However, the main cause of male sterility was the absence of cytokinesis after telophase II. Instead of the typical tetrads of microspores, four nucleate coenocytic microspores were...

A MARHAHIZLALÁS GAZDASÁGOSSÁGÁNAK VIZSGÁLATA EGY SOMOGY MEGYEI VÁLLALKOZÁSBAN
Provedor de dados: 31
Autores: Csonka,   Arnold; Kemeny,   Gabor.
Az anyatehén állomány fajtaátalakítására irányuló döntés két évjáraton elvégzett mérések tapasztalata alapján a hizlalási tevékenység szempontjából is indokoltnak bizonyult. A takarmányozás költségeinek elemzése alapján leszögezhetjük, hogy a marhahizlalásban nem engedhető meg a gyenge minőségű, irreálisan alacsony hozamú és ezáltal rendkívül drága tömegtakarmány etetése. Igaz ez akkor is, ha a magas önköltség elismerése által hozzájárul más ágazatok eredményéhez. Ezt a speciális természeti adottságú termőterület sem indokolja, hiszen megfelelő technológiával és odafigyeléssel a gyenge termőképességű táblákon is meg tudták duplázni a hozamot. A nyereséges termelés alapvető feltétele a tudatos, szakszerű tömegtakarmány-termesztés. A tevékenység eredményének...

A MERGE Model with Endogenous Technological Change and the Cost of Carbon Stabilization
Provedor de dados: 31
Autores: Kypreos,   Socrates.
Two stylized backstop systems with endogenous technological learning formulations (ETL) are introduced in MERGE: one for the electric and the other for the non-electric markets. Then the model is applied to analyze the impacts of ETL on carbon-mitigation policy, contrasting the resulting impacts with the situation without learning. As the model considers endogenous technological change in the energy sector only some exogenous key parameters defining the production function are varied together with the assumed learning rates to check the robustness of our results. Based on model estimations and the sensitivity analyses we conclude that increased commitments for the development of new technologies to advance along their learning curves has a potential for...

A Meta-Analysis of Genetically Modified Food Valuation Studies
Provedor de dados: 31
Autores: Lusk,   Jayson L.; Jamal,   Mustafa; Kurlander,   Lauren; Roucan,   Maud; Taulman,   Lesley.
A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. To examine this body of work, a meta-analysis was conducted of 25 studies that, in aggregate, report 57 valuations for GM food. Findings indicate as much as 89% of the variation in existing value estimates for genetically modified food can be explained by an econometric model that controls for (a) the characteristics of the sample of consumers studied, (b) the method for eliciting consumers' valuation, and (c) characteristics of the food being valued. Each of these factors has a statistically significant effect on estimated premiums for non-GM food.  Results of...

A Meta-Analysis of the Willingness to Pay for Reductions in Pesticide Risk Exposure
Provedor de dados: 31
Autores: Florax,   Raymond J.G.M.; Travisi,   Chiara M.; Nijkamp,   Peter.
The use of environmental policy instruments such as eco-labelling and pesticide taxes should preferably be based on disaggregate estimates of the individuals’' willingness to pay (WTP) for pesticide risk reductions. We review the empirical valuation literature dealing with pesticide risk exposure and develop a taxonomy of environmental and human health risks associated with pesticide usage. Subsequently, we use meta-analysis to investigate the variation in WTP estimates for reduced pesticide risk exposure. Our findings show that the WTP for reduced risk exposure is approximately 15% greater for medium, and 80% greater for high risk-levels, as compared to low risk levels. The income elasticity of pesticide risk exposure is generally positive, although not...

Hazánk Európai Uniós csatlakozása után várható, hogy a kedvezőtlen adott-ságú mezőgazdaságilag művelt területek jelentős része kikerül a mezőgazdasági művelésből. Ezek a földterületek apróvad-gazdálkodás céljaira rendkívül jól hasznosíthatók. Ezeknek a létrehozásához ki kell dolgozni a megfelelő támogatási rendszert. (Az eddig ismert programok között a vadgazdálkodás csupán csak széljegyzetként szerepelt.) A vadgazdálkodási alap élőhely-fejlesztési támogatásait hosszú távra célszerű megtervezni. A hatékonyság mérése érdekében korszerű létszámbecslést és az ezekből származtatott hasznosítás-tervezést indokolt alkalmazni. A jelenleg folytatott folyamatos hasznosítási gyakorlattal szemben az állo-mány létszámváltozásait követő hasznosítás szükséges. Ehhez meg...

A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops
Provedor de dados: 21
Autores: Pedersen, Anders; Stoumann Jensen, Lars; Thorup-Kristensen, Kristian.
The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment. But will it always be an advantage for the farmer to  grow a catch crop? This will depend on factors such as soil mineral nitrogen level, soil water holding capacity, winter precipitation, rooting depth and N demand of the scceeding crop. These factors interact, and it can be very difficult for farmers or advisors to use this information to decide whether growing a catch crop will be beneficial. To analyse the effect of catch crops under different Danish soil and precipitation conditions, we used the soil, plant and atmosphere model Daisy.

A model for the importance of large arborescent palms in the dynamics of seasonally-dry amazonian forests
Provedor de dados: 49
Autores: Salm,Rodolfo; Jalles-Filho,Euphly; Schuck-Paim,Cynthia.
In this study we propose a model that represents the importance of large arborescent palms in the dynamics of seasonally-dry Amazonian forests. Specifically, the model is aimed at guiding the investigation of the role of large arborescent palms on forest regeneration and succession. Following disturbance, the high level of luminosity reaching recently formed forest gaps favors the quick proliferation of shade-intolerant lianas that, by casting shade on the crowns of mature forest trees and increasing tree-fall probability, suppress forest succession. Due to their columnar architecture palm trees are, however, not severely affected by vines. As the palms grow, the canopy at the gaps becomes gradually higher and denser, progressively obstructing the passage...

Autores: Gramig,   Benjamin M.; Horan,   Richard D.; Wolf,   Christopher A.
This paper uses a principal-agent model to examine incentive compatibility in the presence of information asymmetry between the government and individual producers. Prior models of livestock disease have not incorporated information asymmetry between livestock managers and social planners. By incorporating the asymmetry, we investigate the role of incentives in producer behavior that influences the duration and magnitude of a disease epidemic.

A model of sediment transport under the influence of surface bioturbation: generalisation to the facultative suspension-feeder Scrobicularia plana
Provedor de dados: 5
Autores: Orvain, Francis.
Flume experiments were designed to study how sediment erodibility was modified by the facultative suspension-feeder Scrobicularia plana living at different densities in sediment beds of various degrees of compaction. Two separate erosion phases were identified from the resuspension kinetics: (1) erosion of an unconsolidated surficial layer (i.e. fluff layer) and (2) the subsequent bed erosion. S. plana were found to influence both erosion phases: (1) erosion rates of the fluff layer were controlled by bioturbation activities, the extents of which were influenced by bivalve density and the degree of compaction of the sediments, and (2) critical thresholds of the subsequent bed erosion decreased as clam density increased, likely due to depressions in the...

A model structure for estimating malaria risk
Provedor de dados: 26
Autores: Hoshen, M.B.; Morse, A.P.
Malaria is one of the leading causes of death in the developing world today. While prevention and treatment methods are available, their large-scale usage is a major drain on governmental budgets, and not applied whenever necessary. For this reason, understanding the endemicity of a region will allow the efficient implementation of suitable prevention methods. More importantly, the prediction of extraordinary malaria outbreaks will allow the recruitment of emergency facilities before transmission becomes widespread. In addition, climate change may influence the endemicity pattern of a region, causing malaria incidence to rise in areas in which it was non-existent or controlled. For all these purposes, a seasonal to decadal malaria forecast is needed. A...

A Modified, Implicit, Directly Additive Demand System
Provedor de dados: 31
Autores: Cranfield,   John A.L.; Preckel,   Paul V.; Hertel,   Thomas W.
A recently developed demand system, nicknamed AIDADS, offers a more general approach to capturing consumption preferences.  AIDADS generalizes the LES by assuming marginal budget shares vary indirectly with expenditure.  AIDADS is limited by the fact that the subsistence parameters are constant across expenditure.  We modify AIDADS by replacing the constant subsistence parameters with a function which varies with utility, and hence expenditure.  The modified AIDADS (MAIDADS) allows subsistence levels to vary with expenditure.  This model is applied to the 1996 International Consumption Project data.  As these data span a wide range of expenditure levels, MAIDADS offers a viable alternative when estimating "global demand systems." Results suggest...

Previous work in experimental economics reveals specific differences in economic behavior, especially reciprocity and free-riding behavior, across cultures.  We expand the possible pallet of cross-cultural behavioral differences that may exist. We hypothesize that different kinds of strategic interaction and individual decision-making behaviors differ across locations. The variety of experiments we use allow us to report multidimensional rather than just single dimensional differences in behavior across locations. In order to build a broad Homo Economicus we conducted economic experiments in four dissimilar locations: Hangzhou, China; Niamey, Niger; Grenoble, France; Manhattan, Kansas; and West Lafayette, Indiana.

A multiplex PCR assay able to simultaneously detect Torque teno virus isolates from phylogenetic groups 1 to 5
Provedor de dados: 56
Autores: Devalle,S.; Niel,C.
Torque teno virus (TTV) is a circular, single-stranded DNA virus that chronically infects healthy individuals of all ages worldwide. TTV has an extreme genetic heterogeneity which is reflected in its current classification into five main phylogenetic groups (1-5). Using specific PCR assays, it has been shown that many individuals are co-infected with TTV isolates belonging to different phylogenetic groups. Here, a multiplex PCR assay was developed, using five recombinant plasmids. Each plasmid carried an insert of different size issued from a TTV isolate belonging to a different group. The assay was able to simultaneously amplify DNAs of TTV isolates belonging to all five phylogenetic groups. Multiplex PCR was then tested satisfactorily on DNAs extracted...

A Nested Logit Model of Strategic Promotion
Provedor de dados: 31
Autores: Richards,   Timothy J.
Retailers use sales "price promotions" for a number of potential reasons.  There is relatively little research, however, on their strategic role among frequently consumed perishable products.  Using a two-stage, nested logit model of retail equilibrium, we show that promotion will be most effective (ie. increase store-level sales) if products are highly differentiated, but stores are relatively similar.  To test this hypothesis, we an oligopolistic model of promotion rivalry with category-level scanner data from the four largest supermarket retailers in a major U.S. metropolitan market.  The results show that promotion has a greater impact on store share than product share, because the elasticity of substitution among stores is larger than the elasticity...

A new video-microscope has been developed for in situ investigation on marine particles. A field of view is produced by a laser beam at 473 nm. Individual cells or particles that entered this field of view appear as individual diffraction-limited spots of light, which are resolved from the dark background. A mobile high-pass optical filter (610 nm) can be controlled and displaced in front of the CCD camera, allowing simultaneously imaging and discrimination between fluorescing and non-fluorescing particles.

A new innovated and cheep model in building artificial reefs
Provedor de dados: 20
Autores: Mahmoud, M.A.; Ammar, M.S.A.
A novel and cheep approach for building artificial reefs was designed in such a way that sediments in an area of high sedimentation rate will be utilized in building the artificial substrate with no further sediment accumulation afterwards. The model consists of several steel cylinders which are soldered together in such a way to form a reef flat, a gentle slope and a steep slope, with two layers of narrow opening meshes (a lower plastic and an upper metallic one). Within a short periode (3 months), a substrate layer of a total of ~ 1 cm was formed between the two meshes, this layer increased to ~2 cm after 9 months. Transplants of the three species Stylophora pistillata, Echinopora gemmacea and Montipora spongiosa grow better when the attaching surface is...

A new Scleromystax species (Siluriformes: Callichthyidae) from coastal rivers of southern Brazil
Provedor de dados: 83
Autores: Britto,Marcelo R.; Reis,Roberto E.
The recently resurrected callichthyid catfish genus Scleromystax includes species occurring in several Brazilian coastal river basins from southern Bahia to southern Santa Catarina. Several character states, especially those related to sexual dimorphism, demonstrate the monophyly of Scleromystax. Examination of Scleromystax specimens sampled from streams in the Ilha de Santa Catarina and Nova Veneza, and the rio Mampituba basin, Santa Catarina and Rio Grande do Sul States, revealed that they constitute a new taxon, and thus the southernmost record for the genus. Scleromystax salmacis, new species, has coloration similar to that of S. macropterus, differing from that species mainly by the absence of a black spot on the base of the median caudal-fin rays,...

Here we describe a new species of Echimyidae Amazonian rodent, Echimys vieirai sp. nov., based on two individuals from the south bank of Amazon river between the lower Madeira river to the right bank of the Tapajós, respectively in the Brazilian states of Amazonas and Pará, Brazil. The main diagnostic characteristic of this new species is the presence of a dorsal median dark maroon stripe on the head, running from the rostrum to the nape. Skull morphology is quite similar to that of Echimys chrysurus (Zimmermann, 1780), but our new species differ from other species in the genus by the development of the alisphenoid canal and dp4 morphology. Additionally, we offer a refinement of the diagnosis of the genera Echimys and Makalata.

Autores: Ortega, A.; Esteve-Raventós, F.
The new species Gymnopilus arenophilus A. Ortega &amp; Esteve-Rav. is described. It is characterized by its particular habitat in sandy, sometimes burned, soils of thermophilous Pinus forests. Macroscopically G. arenophilus resembles G. penetrans, from which it differs in the larger spores and the scarcely bitter taste. Microscopically G. arenophilus reminds of G. fulgens, with which it has probably been mistaken in the past. The latter species has very different macroscopical features, spore ornamentation and a paludicolous habitat. A discussion of European and some non-European related species is also given.

Measuring fish on a market or on board a vessel is the most common action taken by biologists all around the world to gather data for stock assessment. The samples coming from this kind of survey are of vector type and are not straightforward to analyse and compare. This paper proposes a generic tool that enables to investigate in any multinomial like sampling scheme. The use of this tool will be discussed based on examples from two different sampling designs. One is a sampling of commercial market categories and the other is a métier based sampling. The research of outliers, misallocated samples or potential bias, the stratification and the analysis of within and between strata variance will be discussed with the objective of constructing the best...

The flying gurnard Dactylopterus volitans preys on benthic animals, mostly crustaceans and small fishes, scratching and probing the bottom with the inner rays of its pectoral fins. We recorded the flying gurnard being followed by two opportunistic predators, the yellow jack Caranx bartholomaei and the coney Cephalopholis fulva at Fernando de Noronha, off northeast Brazil. Albeit not actually digging the substrate, the flying gurnard acts as a nuclear species by exploring algae tufts and by its wandering near the boulders and ledges, disturbing and flushing out hidden animals which thus...

A non-linear viscoelastic viscoplastic model for the behaviour of polyester fibres
Provedor de dados: 5
Autores: Chailleux, Emmanuel; Davies, Peter.
In this study the macroscopic analysis proposed by Schapery has been applied to model the non-linear viscoelastic and viscoplastic behaviour of polyester fibres. First, a special non-contact extensometry method has been developed in order to measure the fibre response without affecting the behaviour of these extremely anisotropic fibres. An accelerated identification method has then been developed. This enables a unique and independent set of parameters to be determined, which separate the reversible and non-reversible mechanisms responsible for measured strains. The model prediction for an arbitrary loading sequence corresponds closely to the measured strains. The model has been applied here at the yarn level but can equally well be used to predict rope...

A nonparametric characteristics model of the demand for milk
Provedor de dados: 21
Autores: Andersen, Laura M.; Blow, Laura; Browning, Martin; Crawford, Ian.
Characteristics models in demand analysis capture the idea that people value goods not For the commodity itself but for the characteristics (or attributes) or embodied in the good. For example, agents may care about the fat content and the taste of different sorts of milk but not the actual type of milk. When we have fewer characteristics than types of good the theory imposes restrictions on observables. We present a revealed preference characteristics model analysis of the demand for milk in Denmark.

A non-randomized comparative study using different doses of acyclovir to prevent herpes simplex reactivation in patients submitted to autologous stem cell transplantation
Provedor de dados: 55
Autores: Atalla,Angelo; Maiolino,Angelo; Guimarães,Maria Angélica; Guimarães,Antonio Carlos; Nucci,Marcio.
The reactivation of Herpes Simplex virus (HSV) occurs in 70% to 80% of patients submitted to autologous stem cell transplantation (ASCT); it increases the severity of chemotherapy-induced mucositis. Therefore, the use of acyclovir in ASCT patients is considered standard practice. However, the minimum dose needed to prevent reactivation is a matter of debate. We compared two doses of acyclovir in a non-randomized fashion in 59 patients submitted to ASCT: 32 patients received a dose of 125 mg/m² IV every six hours and the subsequent 27 patients received a dose of 60 mg/m² IV every six hours. Viral excretion was evaluated through weekly viral culture of oral swabs. Grade 4 mucositis was more frequent in Group 1 (p= 0.03). The reactivation rates in Groups 1...

A Note on the Appropriate Measure of Tax Burden on Foreign Direct Investment to the CEECs
Provedor de dados: 31
Autores: Bellak,   Christian; Leibrecht,   Markus; Romisch,   Roman.
In this note we show that tax-rate elasticities of Foreign Direct Investment (FDI) to Central and East European Countries (CEECs) derived from statutory corporate income tax rates (STRs) are likely to be flawed. From a conceptual point of view STRs are problematic as they neither capture tax base effects, nor effects of the home country, the international or the supranational tax laws on the corporate tax burden. Concerning FDI, from an empirical point of view STRs are questionable as their behavior over time and between country-pairs may be very different from that of the conceptually superior bilateral corporate effective average tax rates (BCEATRs). We compare the variability of STRs and BCEATRs of seven major home countries of FDI in eight major CEEC...

A note on the environmental costs of aggregates
Provedor de dados: 31
Autores: Berck,   Peter.
The opening of a new site for the production of aggregates has both direct and indirect impacts on the environment. The indirect impacts include changes in the environmental costs of hauling aggregates and possible changes in the level of construction activity. In this note, we show that the most likely effect of a new aggregate site is to reduce the truck miles used for aggregate hauling, which is an environmental benefit. We also show that the change in construction activity induced by a new site is likely to be extremely small.

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

A novel Kv1.1 potassium channel blocking toxin from the venom of Palamneus gravimanus (Indian black scorpion)
Provedor de dados: 80
Autores: More,S. S.; Mirajkar,K. K.; Gadag,J. R.; Menon,K. S.; Mathew,M. K.
A peptide toxin was isolated from the venom of Palamneus gravimanus, the Indian black scorpion, to block human Kv1.1 channels expressed in Xenopus laevis oocytes. A 4.5 kD peptide (toxin), as confirmed by SDS-PAGE, was purified to homogeneity by ion exchange chromatography using CM-Sephadex C-25 followed by Sephadex G-50 gel filtration. Palamneus gravimanus toxin (PGT) selectively blocks the human cloned voltage-gated potassium channel hKv1.1 in a two-electrode voltage-clamp (TEVC) technique. The results obtained indicate that the toxin blocks the hKv1.1 channel at a nanomolar concentration range (Ki value of 10 nM) of the peptide to the external side of the cell. The blockage seems to be voltage-dependent. Comparative structure of PGT (a 4.5 kD peptide)...

A Panel Data Analysis of the Determinants of Farmland Price: An Application to the Effects of the 1992 Cap Reform in Belgium
Provedor de dados: 31
Autores: Duvivier,   Romain; Gaspart,   Frederic; Frahan,   Bruno Henry de.
This study identifies the effects of the 1992 and subsequent CAP reforms on arable farmland price in Belgium. We first propose a brief literature review of studies identifying the determinants of farmland price. Afterwards, we use a panel data set to estimate a capitalization model of farmland price. We first show that the compensatory payments introduce by the 1992 CAP reform exert a positive effect on the arable farmland price in Belgium. We also identify a structural break in the land price equation after the adoption of the new support instruments as well as a regional break between Wallonia and Flanders.

A Partial Equilibrium Approach of Modeling Vertical Linkages in the U.S. Flat Rolled Steel Market
Provedor de dados: 31
Autores: Fetzer,   James J.
This paper models linkages between upstream and downstream goods in the U.S. market for flat-rolled steel. These vertical linkages are important to account for when estimating the impact of trade restrictions on imports of flat rolled steel because some types of flat rolled steel are predominately used to produce other types of flat rolled steel and in some cases also make up a large share of their production costs. Previous research has modeled the linkages between upstream and downstream goods with CGE models and vertically linked partial equilibrium models. Drawing upon this literature, this paper builds a vertically linked version of the CES COMPAS model that incorporates vertical linkages as constant cross price elasticities in both downstream supply...

A Perspective on the Evolution of e-Dialogues Concerning Interdisciplinary Research on Sustainable Development in Canada
Provedor de dados: 7
Autores: Dale, Ann; Royal Roads University; ann.dale@royalroads.ca.
Sustainable development research is inherently interdisciplinary; it requires the conscious search for unifying concepts that foster and reinforce understanding across disciplines. In addition, the number of sectors and actors involved in potential solutions requires a multistakeholder approach to decision making. The challenge of sustainable development research increasingly presents itself as a problem-solving activity. It involves producing useful knowledge through applied research. It is normative and not value-free. It involves complex issues of polity and culture. Thus, sustainable development research needs novel methods for research, for bringing together expertise that crosses disciplines and sectors, and for informing policy development. It also...

This paper describes preliminary work on establishing a pilot project for carbon sequestration. The project is intended to simulate the structure of the Permanent Forest Sinks Initiative, a program that may extend to the national level under the supervision of the Ministry of Agriculture and Forestry. In the process of establishing the project, we will identify opportunities and barriers for landowners to engage in the management system of “carbon farming”. We will also use the results of the process to inform policymakers of potential improvements to the Permanent Forest Sinks Initiative and to demonstrate to landowners the benefits of this management system.

Following recent phylogenetic studies of the families and genera of Dioscoreales, the identification of monophyletic infrageneric taxa in the pantropical genus Dioscorea is a priority. A phylogenetic analysis based on sequence data from the plastid genes rbcL and matK is presented, using 67 species of Dioscorea and covering all the main Old World and selected New World lineages. The analysis used 14 outgroup taxa, including Trichopus Gaertn., Tacca J.R. &amp; G. Forster, Stenomeris Planch., Burmannia L. and Thismia Griff. The main findings are: a) that a clade of rhizomatous taxa is sister to the rest of Dioscorea; b) the main Old World groups (such as the right-twining D. sect. Enantiophyllum) are monophyletic and c) there are two distinct lineages among...

We present a 5.3- Myr stack ( the " LR04'' stack) of benthic delta(18)O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic delta(18)O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the early Pliocene. We also present a new LR04 age model for the Pliocene- Pleistocene derived from tuning the delta(18)O stack to a simple ice model based on 21 June insolation at 65degreesN. Stacked sedimentation rates provide additional age model constraints to prevent overtuning. Despite a conservative tuning strategy, the LR04 benthic stack exhibits significant coherency with insolation in the...

A Policy Impact Model for Organic Farming in Switzerland
Provedor de dados: 21
Autores: Sanders, Juern; Lampkin, Nicolas; Midmore, Peter; Stolze, Matthias.
Although organic farming has expanded significantly in Europe in the last decade, a sectoral policy model is still missing that is able to analyse the impact of policy measures on organic farming. The use of programming models in the form of a sector-consistent farm group model seems to be a promising model approach, whereas applied general equilibrium models are regarded as less promising. An example is given for a policy impact model for organic farming. The bottom-up structure of this type of model makes it possible to analyse the impact of policy measures on farm incomes and volumes of production of organic and conventional farms at farm, regional and sectoral level.

A poorly known case of watershed transposition between the São Francisco and upper Paraná river basins
Provedor de dados: 83
Autores: Moreira Filho,Orlando; Buckup,Paulo Andreas.
During construction of the Furnas hydroelectric power dam in the upper rio Paraná basin in the early 1960s, the rio Piumhi drainage outflow was diverted into the headwaters of the São Francisco river basin. The rio Piumhi was a right bank tributary of the rio Grande, which unites with the rio Paranaíba to form the rio Paraná. The transposition allowed the entire fish fauna of the rio Piumhi and associated swamps, lakes, and tributaries to intermingle with the fish fauna of the São Francisco basin via the ribeirão Sujo, a right bank tributary of the São Francisco. The transposition of the watershed may have had a major impact on the current composition of the fish fauna of the upper rio São Francisco watershed.

Autores: Taylor,   Roy Justin; Sterns,   James A.
The authors address the fundamental question, "How does one analyze the potential of a given product for a given market?" A review of the literature suggests that numerous authors have proposed a relatively consistent set of questions that need to be addressed, information sought and key issues to consider when conducting market assessments.  The goal of this paper is to review this literature and assemble a set of references that provide insights on how to analyze the market potential of agricultural and food products. This process is of growing importance as U.S. agricultural producers and processors seek to market differentiated products, seek out direct marketing opportunities and focus on meeting consumer preferences for food product attributes.

A preliminary analysis of death cause, capture-related mortality, and survival of adult red deer in northwestern Patagonia
Provedor de dados: 67
Autores: Flueck,Werner T; Smith-Flueck,Joanne M; Bonino,Never A.
The red deer (Cervus elaphus), among the world´s 14 most invasive exotic mammals, has recently arrived in Patagonia. Forty-seven deer were captured, marked with radio collars, and monitored in order to determine survival rates and identify causes of death. Net gunning from a helicopter allowed captures to be evenly distributed through the study area and in a timely manner. The absence of capture related mortality in our study agrees with previously reported low rates for this method. Animals were monitored for periods ranging from 5 to 2611 days. Ten animals provided censored values due to radio failures or being shot: they survived on average 811 days (SE = 221) after capture. Ten animals experienced natural deaths with an average time alive after capture...

Autores: Frisvold,   George B.; Bicknell,   Kathryn; Bicknell,   Ross.
The objective of this research is to undertake an ex ante economic analysis of basic scientific research that aims to identify the gene(s) that control apomictic reproduction, with the ultimate aim of transferring the characteristic into commercially important crops. This paper reports very preliminary results, using the introduction of apomixis into rice as a case study. Apomixis is a natural, asexual method of plant reproduction resulting in offspring that are genetically identical to the mother plant. Apomixis promises to revolutionize plant breeding by providing a system for crop improvement that allows any desired variety, including hybrids, to breed true. This ability will make both breeding and seed production more efficient. It offers the...

Autores: Fennessy, S.T.; Brash, J.M.
This study investigated age and growth of Otolithes ruber, found in KwaZulu-Natal, South Africa. The specimens were collected from prawn trawlers that operate off the shallow water Tugela Bank and from a recreational boat fishery in Durban. Estimates of age and growth parameters were based on the examination of sectioned sagittal otoliths. There was difficulty in estimating growth parameters for separate sexes because the small fish were not sexed and the numbers of males was low. Periodicity of growth zone formation was assumed to be annual although periodicity of growth zone deposition could not be established by marginal zone analysis. The von Bertalanffy growth curve was used to describe the combined male and female growth of O. ruber: Lt = 419mm TL...

Autores: Castellini,   Alessandra; Ragazzoni,   Alessandro; Valentini,   T.
This paper aims to supply a comprehensive account of a particular sector of the fisheries industry.  TH increase of demand for fish products has involved an uncontrolled exploitation of marine reserves and fishing has reached its threshold of biological sustainability.  For these reasons, aquaculture has grown in a corresponding manner in the recent past.  The present survey starts from these considerations and aims to describe the general situation of world-wide, European and Italian aquaculture and then to examine the farming and marketing of a particular kind of product, Penaeus spp., which significantly affects global production in terms of value but not of quantity.

The objective of the study is to determine cost-effective interventions that will reach the critical mass of players within the Philippine organic rice value chain, with the requirements of the market as the starting point of the research. To design strategies and programs necessary for the organic rice industry to flourish, the requirements of the target customers were cross-matched against the competencies, capabilities and resources of both the Philippine Rice Research Institute (PhilRice) and the existing players.     The subsector analysis involved the determination of functions, participants, markets and market channels for the current organic rice produced in the Philippine Archipelago. Benchmarking with progressive and organic produce-exporting...

A preliminary survey of foliar sclerenchyma in neotropical Loranthaceae
Provedor de dados: 16
Autores: Kuijt, J.; Lye, D.
The foliar sclerenchyma of all genera of neotropical Loranthaceae is surveyed by means of cleared leaves, using selected species. Three general categories of sclerenchyma are recognized. Fibers may form discontinuous or continuous bundles associated with veins or, more rarely, occur as individual cells. Sclereids, often of the astrosclereid type, are present in varying concentrations, or may be absent. Cristarque cells are very common, and occasionally extremely abundant, but are lacking in several genera. The survey includes information on terminal tracheids which are almost invariably present. Attention is drawn to the systematic significance of sclerenchyma where warranted.

A Profile of Farmers' Market Consumers and the Perceived Advantages of Produce Sold at Farmers' Markets
Provedor de dados: 31
Autores: Wolf,   Marianne McGarry; Spittler,   Arianne; Ahern,   James.
This study examines responses of 336 produce consumers in San Luis Obispo County, California, to compare the profile of farmers’' market shoppers to those who do not shop at farmers'’ markets. The characteristics of produce sold in farmers’' markets are compared to those sold at supermarkets to determine why consumers shop in farmers’' markets. This examination of the demographic profile of farmers’' market produce consumers indicates that they are more likely to be female, married, and have completed post graduate work. The age levels, income levels, and employment status are similar between farmers'’ market shoppers and farmers'’ market non-shoppers. Farmers'’ market shoppers indicate that cooking and family meals are important to them. Consumers...

A Pseudo-Sequential Choice Model for Valuing Multiple Environmental Policy or Program Components in Contingent Valuation Applications
Provedor de dados: 31
Autores: Volinskiy,   Dmitriy; Bergstrom,   John C.; Cornwell,   Christopher M.
The study proposes a discrete-choice model for environmental policy/program valuation, to be used in cases when several policies are valued sequentially. The stochastic specification of the model is consistent with the transitivity and continuity axioms of utility analysis. An empirical methodology for the model is suggested. An application of this model to WTP estimation for Little Tennessee River watershed ecosystem restoration is provided. Findings from the application agree with the hypothesized agent's behavior.

A quantitative analysis of forest fragmentation in Los Tuxtlas, southeast Mexico: patterns and implications for conservation
Provedor de dados: 97
Autores: MENDOZA,EDUARDO; FAY,JOHN; DIRZO,RODOLFO.
Habitat loss is a critical threat to tropical biodiversity and its quantification constitutes a central conservation issue. Typically, assessments have been based on deforestation rates statistics. However, this overlooks the effects brought about by the spatial reconfiguration of the remaining habitat: fragmentation. We present an analysis of fragmentation in a Neotropical site aimed at: (a) devising a protocol for its quantification, (b) using such protocol to provide insights on the ecological consequences of fragmentation, (c) exploring its applicability to address the hypothesis that forest size-inequality decreases with elevation, an indicator of habitat accessibility. We applied the Gini coefficient (G) and the Lorenz curve to analyze fragment-size...

A radiographic method to estimate lung volume and its use in small mammals
Provedor de dados: 48
Autores: CANALS,MAURICIO; OLIVARES,RICARDO; ROSENMANN,Mario.
In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V*L = 0.496 · V RX &amp;#8776; 1/2·V RX , where V RX is a measurement obtained from the x-ray that represents the volume of a rectangular box containing the lungs and mediastinum organs. The proposed formula may be interpreted as the volume of an ellipsoid formed by both lungs joined at their bases. When that relationship was used to estimate lung volume, values similar to those expected from allometric relationship were found in four rodents. In two others, M. musculus and R. norvegicus, lung volume was similar to reported data, although...

A rainfall simulation study on the relationships between soil test P versus dissolved and potentially bioavailable particulate phosphorus forms in runoff
Provedor de dados: 21
Autores: Uusitalo, Risto; Aura, Erkki.
Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, calling for other ways to predict them. Such predictions could be based on soil loss and available soil P indices, e.g., agronomic P status. To study correlations between P pools in runoff versus soil P saturation (by Mehlich 3 extraction; DPSM3) and acetate soil test P (PAc), 15 clayey soils of south Finland were subjected to laboratory rainfall simulation. Runoff from these simulations was analyzed for concentrations of suspended soil (TSS), dissolved molybdate-reactive P (DRP), total P (TP), and, as normalized to soil loss, potentially bioavailable forms of...

A Rapid and Efficient Method for Purifying High Quality Total RNA from Peaches (Prunus persica) for Functional Genomics Analyses

Prunus persica has been proposed as a genomic model for deciduous trees and the Rosaceae family. Optimized protocols for RNA isolation are necessary to further advance studies in this model species such that functional genomics analyses may be performed. Here we present an optimized protocol to rapidly and efficiently purify high quality total RNA from peach fruits (Prunus persica). Isolating high-quality RNA from fruit tissue is often difficult due to large quantities of polysaccharides and polyphenolic compounds that accumulate in this tissue and co-purify with the RNA. Here we demonstrate that a modified version of the method used to isolate RNA from pine trees and the woody plant Cinnamomun tenuipilum is ideal for isolating high quality RNA from the...

A rapid screening method for cutinase producing microorganisms
Provedor de dados: 58
Autores: Macedo,Gabriela Alves; Pio,Tatiana Fontes.
Both cutinase and lipase belong to the esterase group of enzymes (EC 3.1.1.X), which are capable of catalyzing the hydrolysis of ester bonds. Cutinase catalyzes the hydrolysis of cutin, an insoluble biopolyester which is the structural component of plant cuticles. As cutinase is an efficient catalyst in watery or organic media, it is potentially appropriate for the detergent, food and cosmetic industries. The objective of this work was to isolate microorganisms from plants and perform a pre-selection of molds showing esterase producing ability. The selected strains were then submitted to fermentation in media containing cutin. The lipolytic and cutinolytic activities of the supernatant were determined in order to differentiate lipase producers from...

This paper investigates the profitability of technical trading rules in US futures markets over the 1985-2004 period.  To account for data snooping biases, we evaluate statistical significance of performance across technical trading rules using White's Bootstrap Reality Check test and Hansen's Superior Predictive Ability test.  These methods directly quantify the effect of data snooping by testing the performance of the best rule in the context of the full universe of technical trading rules.  Results show that the best rules generate statistically significant economic profits only for two of 17 futures contracts traded in the US.  This evidence indicates that technical trading rules generally have not been profitable in US futures markets after correcting...

A reassessment of the role of serotonergic system in the control of feeding behavior
Provedor de dados: 42
Autores: Medeiros,Magda A.; Costa-e-Sousa,Ricardo H.; Olivares,Emerson L.; Côrtes,Wellington S.; Reis,Luís C.
The role of serotonergic system in the feeding behaviorwas appraised by electrolytic lesions in the dorsal raphe nucleus (DRN) and administration of para-chlorophenylalanine (PCPA, 3 mg/5 mul, icv). Chronic evaluations were accomplished through 120 and 360 days in PCPA-injected and DRN-lesioned rats, respectively. Acute food intake was evaluated in fasted rats and submitted to injection of PCPA and hydroxytryptophan (LHTP, 30 mg/kg, ip). DRN-lesioned rats exhibited 22-80% increase in food intake up to sixth month, whereas the obesity was evident and sustained by whole period. In PCPA-injected rats was observed an initial increase in the food intake followed by hypophagy from 25th to 30th day and a transitory increase of body weight from 5th to 60th day. In...

Autores: Azevedo,Cristina Maria do Amaral.
A implementação, em nível nacional, da Convenção sobre Diversidade Biológica, especialmente dos artigos 8j e 15, que tratam respectivamente do conhecimento tradicional e do acesso aos recursos genéticos e da repartição dos benefícios provenientes da sua utilização, tem gerado intenso debate quanto ao seu impacto sobre a pesquisa. No Brasil vigora atualmente a Medida Provisória 2.186-16/01 (MP) que instituiu as regras para o acesso a e a remessa de componentes do patrimônio genético e o acesso a conhecimentos tradicionais associados. Essa norma previu a criação da autoridade nacional competente o Conselho de Gestão do Patrimônio Genético (CGEN) no âmbito do Ministério do Meio Ambiente, o qual iniciou suas atividades em abril de 2002.

A Report on the Management of Saltwater Crocodiles (Crocodylus porosus) in the Northern Territory: Results of a Survey of Pastoralists
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
The management of saltwater crocodiles (Crocodylus porosus) in the Northern Territory is an important component of the State’s wildlife management policy. It encompasses saltwater crocodile control (the removal of problem crocodiles dangerous to humans and livestock), and the regulation of harvesting, farming and ranching of saltwater crocodiles for the production of commercial products. The distribution of saltwater crocodiles and their habitats often extend onto private and communal lands along the coastal belt of the Northern Territory,  and therefore are a concern of landholders both Aboriginal and pastoral. This report presents the findings of a study of managers of Northern Territory cattle properties (pastoralists). Their attitudes are surveyed...

A revision of European species of Leccinum Gray and notes on extralimital species
Provedor de dados: 16
Autores: Bakker, Henk C. den; Noordeloos, Machiel E.
This paper deals with the generic delimitation of Leccinum and the taxonomic and nomenclatural implications of the phylogenetic results presented in previous papers by Den Bakker et al. (2004a, 2004b). 28S nrDNA data, used in the past to answer questions concerning genus delimitation of Leccinum, are reanalysed. The phylogenetic inferences based on 28S nrDNA largely coincide with Leccinum sensu Singer. The only species that is excluded from Leccinum is L. eximium. At least one truffle-like genus, Chamonixia, should be included in Leccinum. Morphological characters proposed in the past to delimit the genus are discussed in the light of the phylogenetic results. It is concluded that there is no single diagnostic morphological character that unites species of...

A revision of the deep-water octopus genus Scaeurgus (Cephalopoda : Octopodidae) with description of three new species from the southwest Pacific Ocean
Provedor de dados: 5
Autores: Norman, Md; Hochberg, Fg; Boucher-rodoni, R.
Deep-water trawl surveys on seamounts around New Caledonia yielded 62 specimens of the little-known genus, Scaeurgus. Members of this genus of octopuses typically occur at depths of 200-500 m in temperate and tropical latitudes worldwide. Prior to this study, Scaeurgus was considered to contain one to two species. The new material from New Caledonia contained a surprising diversity of Scaeurgus species from a small area: three distinct new species are described and limited material of a further two taxa is reported. A pygmy member of this genus is reported for the first time. Distributions of these new taxa are consistent with reports of high endemism on the seamount systems in this region. Fifty-eight of the 62 specimens were collected from seamounts,...

A risk infection simulation model for fusarium head blight of wheat
Provedor de dados: 102
Autores: Del Ponte,Emerson M.; Fernandes,José Maurício C.; Pavan,Willingthon.
Fusarium Head Blight (FHB) is a disease of great concern in wheat (Triticum aestivum). Due to its relatively narrow susceptible phase and environmental dependence, the pathosystem is suitable for modeling. In the present work, a mechanistic model for estimating an infection index of FHB was developed. The model is process-based driven by rates, rules and coefficients for estimating the dynamics of flowering, airborne inoculum density and infection frequency. The latter is a function of temperature during an infection event (IE), which is defined based on a combination of daily records of precipitation and mean relative humidity. The daily infection index is the product of the daily proportion of susceptible tissue available, infection frequency and spore...

Autores: Bonilha,A.M.M.; Saraiva,R.M.; Kanashiro,R.M.; Portes,L.A.; Antonio,E.L.; Tucci,P.J.F.
Nine lead electrocardiograms of non-infarcted (N = 61) and infarcted (N = 71) female Wistar rats (200-250 g) were analyzed in order to distinguish left ventricle myocardial infarction (MI) larger than 40% (LMI) from MI smaller than 40% (SMI). MI larger than 40% clearly caused a deviation of ÂQRS and ÂT from normal values of 270-360 degrees to 90-270 degrees. Infarcted rats showed Q wave in D1 larger than 1 mm with 94% sensitivity and 100% specificity. The sum of QRS positivity in V1, V2 and V6 lower than 10 mm identified MI with 82% sensitivity and 100% specificity. The data showed that MI can be easily and reliably diagnosed by electrocardiogram in the rat. However, contradicting what is frequently believed, when specificity and sensitivity were analyzed...

A Sectoral Model for Analyzing Alternative Technologies in Pig Farming
Provedor de dados: 31
Autores: Helming,   John F.M.; Surry,   Yves R.
This paper develops a demand-augmented positive mathematical programming model to analyze the relationship between environmental pollution from animal manure, manure policies and different pork production systems in the Netherlands. The model features substitution of conventional and alternative pork from the demand side and endogenous manure prices. It is found that policies that put restrictions on environmental pollution from manure decreases the conventional pork production systems, but increases organic pork production systems. The latter is considered an improved system from both an animal welfare and environmental point of view.

A semi-automatic computerized method to measure baroreflex-mediated heart rate responses that reduces interobserver variability
Provedor de dados: 56
Autores: Soares,P.P.S.; Ushizima,M.R.; Krieger,E.M.; Irigoyen,M.C.C.
Arterial baroreflex sensitivity estimated by pharmacological impulse stimuli depends on intrinsic signal variability and usually a subjective choice of blood pressure (BP) and heart rate (HR) values. We propose a semi-automatic method to estimate cardiovascular reflex sensitivity to bolus infusions of phenylephrine and nitroprusside. Beat-to-beat BP and HR time series for male Wistar rats (N = 13) were obtained from the digitized signal (sample frequency = 2 kHz) and analyzed by the proposed method (PRM) developed in Matlab language. In the PRM, time series were low-pass filtered with zero-phase distortion (3rd order Butterworth used in the forward and reverse direction) and presented graphically, and parameters were selected interactively. Differences...

A semiotic polyocular framework for multidisciplinary research in relation to multifunctional farming and rural development
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted; Langvad, Anne Mette Sørensen.
The concept of multifunctional farming rises out of a problematization of the role of agriculture in society and, in particular, in relation to rural development. Hitherto multifunctional farming has primarily been used as a notion on the relationship between agriculture and society concerning the range of commodity and non-commodity goods that farms provide for society. But the agro-economic achievements together with societal development have led to a point where praxis is questioned and discourse potentially reopened. In an indirect way, the notion of multifunctionality reflects, that aspects not captured by the distinction between commodity and non-commodity need to be reintroduced.  This paper offers a new framework (theoretical and methodical)...

A Semi-Selective agar medium to detect the presence of Xanthomonas axonopodis pv. malvacearum in naturally infected cotton seed
Provedor de dados: 102
Autores: Mehta,Yeshwant R; Bomfeti,Cleide; Bolognini,Viviani.
A semi-selective agar medium was developed for detection of Xanthomonas axonopodis pv. malvacearum (Xam) in cotton (Gossypium hirsutum) seed. The basic medium was peptone-sucrose-agar (PSA). Criteria for the semi-selective medium were the typical colony characters of Xam and its pathogenicity on cotton. Several systemic fungicides and antibiotics in different concentrations were tested alone or in combination with others. The final composition of the semi-selective agar medium was established after several attempts in order to inhibit most of the fungal and bacterial saprophytes and favour the development of Xam. It contained PSA + cyclohexamide, cephalexin, pencycuron, triadimenol and tolylfluanid. The bacteria were recovered from naturally infected seeds...

The objective of this study was to develop a rapid and effective method of sexing juvenile sea bass with minimum labour and material. To this end, the gonad squash mount technique was applied along with macroscopic techniques for sexing a large number of experimental fish at the age of 215-275 days post fertilization (p.f.). At this age, 90% of the 3894 fish could be unambiguously sexed by macroscopic examination of their gonads, whereas the remaining proportion was identified using squash mount preparations (10%). The accuracy of the observations was measured up to classical histology procedures. Undifferentiated fish accounted for 0.1% of the total population only. The application of the squash mount technique holds out the prospect of considerable...

A state-space model to derive bluefin tuna movement and habitat from archival tags
Provedor de dados: 5
Autores: Royer, Francois; Fromentin, Jean-marc; Gaspar, P.
Archival tagging provides a unique way to study the spatial dynamics and habitat of pelagic fish. This technique generates lagrangian data of a particular type in marine ecology: although highly informative about processes at different scales (e.g. horizontal movements versus diving behaviour), such data are impaired by location errors and the lack of combination with actual environmental variability. The present paper introduces a framework for modelling bluefin tuna movement in relation to its habitat, using records of light, depth and temperature from archival tags. Based on data assimilation concepts and methods, we show how an explicit formulation of the observation process and the statistics of external variables (e.g. ambient temperature) can...

A Stochastic-Dynamic Model of Costly Reversible Technology Adoption
Provedor de dados: 31
Autores: Baerenklau,   Kenneth A.; Knapp,   Keith C.
We develop a stochastic-dynamic model of technology adoption that imposes fewer restrictions on behavior than do previous studies of similar decision problems.  Like these previous studies, our model is forward-looking and can be used to demonstrate the additional "hurdle rate" that must be met before adoption will take place when the future state of the world is uncertain.  Unlike these previous studies, our approach does not impose the untenable assumptions that investment in a new technology is irreversible or that technologies have unlimited useful lifetimes.  Rather, we address the more reasonable situation of costly reversibility and limited lifetimes.  Our solution method utilizes Bellman's equation and standard dynamic programming techniques....

A strategy to identify genomic expression at single-cell level or a small number of cells

Recent advances in functional genomics allow us to estimate the expression of several thousands of genes in the mammalian genome. Techniques such as microarrays, expressed tag sequencing (EST), serial analysis of gene expression (SAGE), subtractive cloning and differential display (DD), and two-dimensional electrophoresis gel have been extensively used to screen and analyze parallel gene expression. Some pathological processes, for example, tumorigenesis and solid tumour growth, in which the former is derived from a single-cell and the latter has a mixed-cell problem, present new challenges to the limit of these functional genomic techniques. To fully understand the functions of cells in tumorigenesis or in heterogeneous solid tumour masses, it is...

We analyzed the performance of 162 normal subjects, subdivided into groups according to age and schooling, in the oral comprehension tasks of the Boston Diagnostic Aphasia Examination translated and adapted to Brazilian Portuguese to obtain a profile of performance for the Brazilian population, as well as cut-off scores for each task, and to determine the best combination of tasks that distinguish normal from aphasic subjects, as a guide for clinicians. The normal subjects were compared to 69 aphasics. Age alone influenced the performance in the designation of actions (subjects above 70 years showing the worst performance); schooling alone influenced the comprehension of forms, colors and numbers (subjects with less than four years of education showing a...

A study of the constitutive heterochromatin and nucleolus organizer regions of Isocopris inhiata and Diabroctis mimas (Coleoptera: Scarabaeidae, Scarabaeinae) using C-banding, AgNO3 staining and FISH techniques
Provedor de dados: 74
Autores: Bione,Edgar; Camparoto,Marjori Leiva; Simões,Zilá Luz Paulino.
Meiotic and mitotic chromosomes of Isocopris inhiata and Diabroctis mimas were studied by standard staining procedures, C-banding, silver nitrate staining and FISH using Apis mellifera 28S rDNA as probe. Isocopris inhiata presented a 2n = 18 (8II+ Xy p) karyotype, composed of meta-submetacentric chromosomes with gradual reduction in size. The karyotype of D. mimas was 2n = 20 (9II+ Xy p), composed of meta-submetacentric (pairs 1, 2, 3, 4 and 7) and acrocentric (pairs 5, 6, 8 and 9) chromosomes, with gradual reduction in size. Analysis of constitutive heterochromatin revealed similar C-banding patterns for both species, showing pericentromeric and telomeric bands and diphasic chromosomes. In addition, the X chromosomes of these species were found to be...

A Study on Economic Analysis of Elephant Foot Yam Production in India
Provedor de dados: 31
Autores: Srinivas,   T.; Ramanathan,   S.
Elephant foot yam is traditionally cultivated on commercial scales in the states of Andhra Pradesh, Tamil Nadu, Kerala and West Bengal. The statistics on area, production and yield of this crop are not available in the literature and this paper has estimated the cost of cultivation, farm income measures and resource-use efficiency of the crop in these states, except West Bengal. The study has indicated the gross cost of cultivation as Rs 1,73,105, Rs 93,450 and Rs 1,68,032 per ha and the benefit-cost ratios as 1.38, 1.38 and 1.50 for elephant foot yam cultivation in Kerala, Andhra Pradesh and Tamil Nadu, respectively. The study has revealed excessive use of all NPK fertilizers in Kerala, indicating the need for rationalization in use of these inputs, while...

A Supermarket-Level Analysis of Demand for Breakfast Cereals: A Random Coefficients Approach
Provedor de dados: 31
Autores: Chidmi,   Benaissa; Lopez,   Rigoberto A.; Cotterill,   Ronald W.
This paper applies the BLP approach to the demand for ready-to-eat cereals (RTECs) at the supermarket-chain level in Boston using IRI monthly data. The Random Coefficient Model is used to estimate the demand for 37 brands of RTECs at the leading supermarkets in the Boston area. The empirical results provide a wealth of consumer behavior information, including own- and cross-price elasticites for 37 brands of RTECs at four leading supermarkets in Boston. The demand for RTECs is generally price elastic (ranging between -3 and -8). Consumers respond positively and strongly to promotion, negatively and strongly to price, calories and fiber, and weakly to sugar content. Income has a strong interactive effect with product characteristics and thus is a useful...

A revision of Mallotus section Philippinenses (former section Rottlera) in Malesia and Thailand is given. Descriptions, distribution maps, habit drawings, and a key to the species are provided. The diagnostic characters for the section are briefly discussed. Five species (M. kongkandae, M. leptostachyus, M. pallidus, M. philippensis, and M. repandus) are recognised. Mallotus chromocarpus is excluded from the section because it has more shared characters with the monospecific genus Octospermum, like the presence of indehiscent fruits, absence of stipules, marginal extrafloral nectaries on the upper side of the leaf blade, broad connectives (shaped umbrella-like), and its occurrence in New Guinea, and is therefore probably closely related to it.

Autores: Weers, D.J. van.
Measurements of many hundreds of the high-crowned cheek teeth of Hystrix specimens from the Euro-Asiatic Pleistocene in the collections of European and Asiatic institutions have been compared with extant species for a revision of the genus. A review is given about the extant genera and species of the family. The number of recognisable Euro-Asiatic species in the fossil record is reduced from eight to five. The European H. (A.) vinogradovi Argyropulo, 1941 is here considered to be a synonym of H. (A.) brachyura Linnaeus, 1758, and the three Asiatic species H. (H.) crassidens Lydekker, 1886, H.

A taxonomic survey of seaweeds from Eritrea
Provedor de dados: 16
Autores: Ateweberhan, M.; Prud’homme van Reine, W.F.
A survey of seaweeds was made in Eritrea in December 1995 and January 1996 on some islands of the Dahlak Archipelago and the surroundings of the port town of Massawa. During our study 101 specific and infraspecific taxa were identified, including 26 Chlorophyta, 20 Phaeophyta and 55 Rhodophyta. The survey resulted in 36 new records for Eritrea (11 Chlorophyta, 7 Phaeophyta and 18 Rhodophyta). Of these Eritrean records, 26 are new for the Red Sea (5 Chlorophyta, 4 Phaeophyta and 17 Rhodophyta). Comparison of records of seaweeds from localities in Eritrea to those from other localities in Eritrea as well as from other coasts of the western Indian Ocean have revealed that the regional distribution of seaweeds in the Red Sea is very patchy and that generally...

Az első hipotézis beigazolódott, valóban van összefüggés a termékek külső szállítási és a raktározási költségei között. Ez minden bizonnyal a logisztikai költségek termékfeldolgozottságtól való függésének tudható be.  A második feltevés – a csoportosíthatóság – csak részben igazolódott be. A mi-relit- és tejtermékek például valóban egyfajta tulajdonságaik miatt kerültek egy csoportba, de az üdítő, péksütemény egységekkel, vagyis a másik két csoportalko-tóval már nehezen indokolható az összetartozásuk. Termékfeldolgozottságuk nem egyezik az előző két egységével, igaz elég távol is helyezkedtek el azoktól.  A harmadik hipotézis nem igazolódott be.

A Test of Forecast Consistency Using USDA Livestock Price Forecasts
Provedor de dados: 31
Autores: Sanders,   Dwight R.; Manfredo,   Mark R.
In traditional tests of forecast rationality, price forecasts are usually differenced to obtain stationarity. However, this data transformation may ignore important long-run information contained in forecasted price levels. Here, the concept of forecast consistency is paired with rationality concepts used in the market efficiency literature to develop a sequential testing procedure for forecast consistency and rationality. USDA quarterly livestock price forecasts do not demonstrate long-run consistency.

A Theoretical and Empirical Analysis of Conservation Reserve Program Participation under Uncertainty
Provedor de dados: 31
Autores: Isik,   Murat.
This paper develops theoretical and empirical models to understand how farmers formulate their participation strategies when deciding to enroll in the Conservation Reserve Program (CRP) under uncertainty.  A theoretical model is employed to obtain the impacts of various factors on the optimal bidding strategies.  A selectivity-based econometric model is then used to estimate the probability of enrollment and determinants of rental payments.  The theoretical results indicate that the optimal bid is positively related to the expected farming income and environmental benefit scores, and it is negatively related to the degree of risk aversion and the variability of returns.  The econometric model shows that land benefits, land attributes, farmer...

A Theory of Natural Addiction
Provedor de dados: 31
Autores: Smith,   Trenton G.; Tasnadi,   Attila.
Economic theories of rational addiction aim to describe consumer behavior in the presence of habit-forming goods. We provide a biological foundation for this body of work by formally specifying conditions under which it is optimal to form a habit. We demonstrate the empirical validity of our thesis with an in-depth review and synthesis of the biomedical literature concerning the action of opiates in the mammalian brain and their effects on behavior. Our results lend credence to many of the unconventional behavioral assumptions employed by theories of rational addiction, including adjacent complementarity and the importance of cues, attention, and self-control in determining the behavior of addicts. Our approach suggests, however, that addiction is...

A Trait Specific Model of GM Crop Adoption among U.S. Corn Farmers in the Upper Midwest
Provedor de dados: 31
Autores: Useche,   Pilar; Barham,   Bradford L.; Foltz,   Jeremy D.
This work offers a new approach to the adoption of GM crop varieties by adopting the econometric methodology of the characteristics-based demand literature. A random utility framework was implemented through different specifications of a conditional (CL) and a mixed multinomial logit (MMNL) model of crop-variety choice. Willingness-to-pay and price elasticity estimates for traits were calculated. The MMNL approach demonstrates that individuals' tastes for some traits significantly vary across the population. Results further suggest that labor saving technologies have a much wider potential to be adopted. Overall, the use of a trait-based model to examine the adoption patterns of GM crop varieties among corn farmers in Minnesota and Wisconsin reveals a new...

A PCR assay was designed for amplification of the highly conserved VP3 gene and a 5' region of the VP1 gene, for the diagnosis of CAV in organ samples of broiler flocks suspected of chicken infectious anemia. A comparison of the VP3/VP1 PCR with in vivo virus isolation revealed 100% agreement of the results, with 13 positive and 3 negative samples in both assays, indicating that the VP3/VP1 PCR is a specific diagnostic method. Tissues from additional 24 broiler chicken flocks, with CAV-like lesions and clinical history were then tested only by the VP3/VP1 PCR and a reference PCR with published primers for the VP1 gene. Nineteen samples resulted positive and one negative in both PCR, while another 4 samples were positive only in the VP3/VP1 PCR. These...

A zöldségfélék fogyasztása a vizsgált időszakban, 1993 és 2002 között 56 és 64 kg/fő/év között ingadozott, de míg a legalacsonyabb jövedelműek csoportjában ez 42,3 kg/fő/év volt csupán, addig a legnagyobb jövedelműek csoportjában ez 83,7 kg/fő/év-et tett ki. Fontos megemlíteni, hogy 2002-ben minden jövedelmi csoportban kevesebb zöldséget fogyasztottak, mint 1993-ban! A tartósított zöld-ségek fogyasztása minden jövedelmi csoportban emelkedett, különösen a legna-gyobb jövedelműek körében.

Abate humanitário de crocodilianos.
Provedor de dados: 14
Autores: CAMPOS, Z.; COUTINHO, M. E.; OLIVEIRA, T. M. de.
Para a implantação da prática de abate humanitário para os jacarés foi desenvolvida pela Gil Equipamentos e a Embrapa Pantanal, a pistola ZILKA (Fig.1). A pistola foi desenvolvida para atender uma solicitação de pesquisa da Embrapa Pantanal a durante a execução do projeto de manejo experimental do jacaré-do-pantanal, Caiman crocodilus yacare, no Pantanal Sul. A pistola causa respostas de sensibilidade nos jacarés com um rápido estado de inconsciência e a incapacidade de respostas a estímulos externos. Essa etapa é fundamental para garantir o abate dentro dos princípios humanitários, uma vez que garantirá a inconsciência dos jacarés até a sangria. A pistola ZILKA também pode ser usada para abate de outros animais criados em cativeiro (ovinos e caprinos) ou...

Abelhas africanizadas Apis mellifera scutellata Lepeletier, 1836 (Hymenoptera: Apidae: Apinae) exploram recursos na floresta amazônica?
Provedor de dados: 36
Autores: Oliveira,Marcio Luiz de; Cunha,Jorge Alcântra.
As abelhas africanas (Apis mellifera scutellata) foram trazidas para o Brasil na década de 1950 e, por acidente, cruzaram-se com outras subespécies de abelhas melíferas européias introduzidas no século XIX. Isso proporcionou o surgimento de híbridos com características predominantes das abelhas africanas, tais como rusticidade e maior capacidade de enxamear, o que lhes permitiu uma rápida adaptação e expansão por quase todo continente americano. Até hoje existem controvérsias se essas abelhas, denominadas africanizadas, causam algum impacto sobre a fauna de abelhas nativas. Nas Américas, as africanizadas estão restritas a regiões de baixas altitudes e de invernos amenos; no Brasil, ocorrem principalmente em áreas urbanas e formações vegetacionais abertas...

Ability of taxonomic diversity indices to discriminate coastal lagoon environments based on macrophyte communities
Provedor de dados: 5
Autores: Mouillot, David; Gaillard, Sylvain; Aliaume, Catherine; Verlaque, Marc; Belsher, Thomas; Troussellier, Marc; Chi, Thang.
Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the "average taxonomic distinctness" (Delta(+)) and the "variation in taxonomic distinctness" (Lambda(+))) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p &lt; 0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p &lt;...

Provedor de dados: 86
Autores: Silva,Fabyano Fonseca e; Muniz,Joel Augusto; Aquino,Luiz Henrique de; Sáfadi,Thelma.
O objetivo deste trabalho foi utilizar o método Bayesiano no ajuste do modelo de Wood a dados de produção de leite de cabras da raça Saanen. Dois grupos de animais da primeira e segunda lactação foram considerados. Amostras das distribuições marginais a posteriori dos parâmetros do modelo de Wood e das funções de produção derivadas desses parâmetros - pico de produção, tempo do pico de produção, persistência e produção total de leite - foram obtidas pelo algoritmo Gibbs Sampler. As inferências foram feitas em cada população e os resultados mostraram diferenças na taxa de decréscimo da produção após o pico e na persistência, indicando maior produção nos animais de segunda lactação. Realizou-se um estudo de simulação de dados para avaliar o método Bayesiano...

Autores: CAMPOLIN, A. I.
O desenvolvimento rural entendido como a somatória de conquistas não apenas no campo econômico, mas também social, político, ambiental e cultural, tem-se constituído preocupação constante dos órgãos de pesquisa e extensão, ONGs e poder público, comprometidos com a melhoria das condições de vida da população do campo. Por outro lado, estas instituições têm sido constantemente criticadas pela ineficácia dos projetos implementados neste sendido. Uma das críticas mais contundentes diz respeito às metodologias que ignoram o protagonismo dos agricultores nos programas de pesquisa e desenvolvimento. O texto a seguir discute a viabilidade de se adotar abordagens qualitativas a na pesquisa em agricultura familiar, explicitando as vantagens deste paradigma para o...

Absence of the A4 peptide in the G4 glycinin subunit of soybean cultivar Enrei is caused by a point mutation in the Gy4 gene
Provedor de dados: 74
Autores: Yu,Kangfu; Poysa,Vaino; Haffner,Margaret; Zhang,Bailing; Woodrow,Lorna.
Functional properties of soy proteins for food are closely related to the composition of their storage protein subunits. Using base excision sequence scanning (BESS), we show that the absence of the A4 peptide in the G4 glycinin subunit of the soybean (Glycine max L.) cultivar Enrei was caused by the same point mutation in the Gy4 gene as previously reported in the soybean cultivar Raiden. Although the genetic relationship between Raiden and Enrei is not known, the same point mutation in their Gy4 genes may indicate that they probably share a related origin. The application of BESS to identify single nucleotide polymorphisms (SNPs) as co-dominant markers for marker-assisted selection (MAS) of a recessive null allele is also discussed.

Absorção de água e proliferação de fungos em madeira de Pinus usada como embalagem para hortaliças
Provedor de dados: 75
Autores: Henz,Gilmar P.; Cardoso,Flávio B.
A madeira é o material mais utilizado para embalagens de hortaliças no Brasil, principalmente por conta de seu baixo custo e alta resistência mecânica. Neste trabalho estimou-se a absorção e a perda progressiva de água de ripas de madeira de Pinus utilizadas na montagem de caixas do tipo "K" em três condições de umidade relativa e o crescimento de fungos em sua superfície. Trinta ripas novas de madeira de Pinus (52 x 6 x 0,6 cm) foram pesadas individualmente, imersas em água durante 1 h e pesadas novamente para avaliar a absorção de água. Em outro experimento, dez ripas foram incubadas ao acaso em cada uma das três câmaras úmidas (61%, 86% e 94% UR) mantidas a 25ºC (±2ºC). A perda progressiva de água foi avaliada por pesagens diárias das ripas...

Absorção de água pelas raízes do limoeiro sob distintas freqüências de irrigação
Provedor de dados: 91
Autores: Santos,Delfran B. dos; Coelho,Eugênio F.; Azevedo,Carlos A. V. de.
Objetivou-se, nesse trabalho, caracterizar a absorção de água pelas raízes do limoeiro 'Taiti' (Citrus latifolia Tanaka) no perfil de solo sob diferentes intervalos de irrigação por microaspersão. O estudo foi realizado em condições semi-áridas, em solo franco arenoso, cuja absorção de água pelas raízes das plantas foi determinada a partir da umidade em diversas posições no perfil do solo entre duas irrigações, por meio de sondas de TDR. A distribuição radicular foi avaliada a partir de dados de comprimento e diâmetro das raízes nas mesmas posições das sondas de TDR. Conforme os resultados, verificou-se que: (i) à medida que as raízes se afastam do microaspersor, a extração de água pelas raízes do limoeiro é reduzida; (ii) o limoeiro extrai mais água do...

Autores: Primavesi,Ana Cândida; Primavesi,Odo; Corrêa,Luciano Almeida; Cantarella,Heitor; Silva,Aliomar Gabriel da.
Os processos fisiológicos das plantas são afetados pelo balanço de cátions e ânions absorvidos. O objetivo deste trabalho foi determinar a absorção de cátions e ânions quando plantas de capim-coastcross receberam doses elevadas de nitrogênio. O delineamento experimental foi o de blocos casualizados com quatro repetições, num esquema fatorial 2x5 - duas fontes de N: uréia e nitrato de amônio, e cinco doses de N: 0, 25, 50, 100, 200 kg ha-1 corte-1 . As doses de N foram aplicadas após cada corte num total de cinco cortes, durante a época das chuvas. A absorção de cátions e de ânions pelo capim-coastcross aumentou com o acréscimo das doses de N dos dois fertilizantes, sendo maior com o nitrato de amônio. Com doses crescentes de N, verificou-se entre os...

Absorção de N, P, K, Ca, Mg e S pelo arroz irrigado influenciada pela adubação nitrogenada
Provedor de dados: 64
Autores: Reis,Moizés de Sousa; Soares,Antônio Alves; Soares,Plínio César; Cornélio,Vanda Maria de Oliveira.
Considerando que ainda não existe um método capaz de avaliar satisfatoriamente a disponibilidade de nitrogênio no solo para as plantas, não sendo possível traçar uma curva de calibração para esse elemento, torna-se necessário trabalhos de pesquisa para estabelecer curvas de resposta em relação a várias doses de nitrogênio, bem como avaliar a resposta de diferentes cultivares. Dessa forma, foi conduzido um experimento em casa-de-vegetação, no Departamento de Ciência do Solo, da Universidade Federal de Lavras, com o objetivo de avaliar o efeito de doses de nitrogênio sobre a produtividade de grãos e a quantidade absorvida e exportada de macronutrientes (N, P, K, Ca, Mg e S) por três cultivares de arroz irrigado.

Absorção e redistribuição do nitrogênio aplicado via foliar em videiras jovens
Provedor de dados: 94
Autores: Brunetto,Gustavo; Kaminski,João; Melo,George Wellington Bastos de; Gatiboni,Luciano Colpo; Urquiaga,Segundo.
A aplicação de nitrogênio via foliar antes da senescência das folhas da videira pode ser uma estratégia para aumentar as reservas deste nutriente nas partes perenes, uma vez que as mesmas são disponibilizadas no início do crescimento vegetativo dos órgãos anuais. O objetivo deste trabalho foi de estimar a absorção e a redistribuição do N adicionado via foliar em videiras jovens. O experimento foi instalado em casa de vegetação na EMBRAPA-Uva e Vinho, no município de Bento Gonçalves (RS). Foram utilizadas as variedades Chardonnay e Riesling Itálico com porta-enxerto 101-14 Mgt. Foi cultivada uma planta por vaso contendo 10kg de solo Neossolo Litólico. A aplicação do N via foliar foi parcelada em três vezes, durante três dias sucessivos. Foram aplicados...

Abundance and distribution of Lithophaga (Mytilidae) in extant and fossil oysters: taphonomic and paleobiological implications
Provedor de dados: 41
Autores: Mauna,Cecilia; Casadío,Silvio; Parras,Ana; Pascual,Marcela.
In this study we analyze the abundance and distribution patterns of Lithophaga patagonica in valves of Ostrea puelchana and compare them to those of Lithophaga sp. observed on the fossil species " Ostrea " patagonica and " Ostrea " alvarezii from the late Miocene Puerto Madryn Formation. No specimen of the fossil oysters showed borings of Lithophaga sp. on the interior surface of the valves. This suggests that they were produced while the oysters were still living and, at the same time, that the oyster beds were buried rapidly after death. In Ostrea puelchana the boring abundance was significantly higher for the left valve and, within it, the areas more heavily bored were the umbones and the platform. The same results were obtained for valves of " Ostrea "...

Abundance of naturally occurring entomopathogenic nematodes and establishment of inoculated Steinernema feltiae in an organic cropping system
Provedor de dados: 21
Autores: Nielsen, Otto; Philipsen, Holger.
The abundance of entomopathogenic nematodes and soil dwelling stages of plant specific insects was studied in an organic cropping system for two years. In addition was the survival of an inoculated strain of Steinernema feltiae studied. The abundance of naturally occurring entomopathogenic nematodes was in general at a low level throughout the observation period (0-26 % positive samples). Inoculated S. feltiae established well when pea was grown in the same or in the following year whereas the nematodes were less able or unable to establish in the other crops (cabbage, carrots, barley, alfalfa/clover). The successful establishment of nematodes, and the abundance in general, correlated well with the presence of plant specific insects.

Acceptable Reforms of Agri-Environmental Policies
Provedor de dados: 31
Autores: Bontems,   Philippe; Rotillon,   Gilles; Turpin,   Nadine.
We consider a model of regulation for nonpoint source water pollution through non linear taxation/subsidization of agricultural production. Farmers are heterogenous along two dimensions, their ability to transform inputs into final production and the available area they possess. Asymmetric information and participation of farmers to the regulation scheme put constraints on the optimal policy that we characterize. We show that a positive relationship between size of land and ability may exacerbate adverse selection effects. We then introduce acceptability constraints and show that the intervention under acceptability amounts to reallocate production towards inefficient farmers who benefit from the reform at the expense of efficient producers. Last, we...

Access to OECD Agricultural Market: A Gravity Border Effect Approach
Provedor de dados: 31
Autores: Olper,   Alessandro; Raimondi,   Valentina.
This paper uses the border effect estimate from a gravity model to assess the level of trade integration in agricultural markets between 22 OECD countries, over the 1995-2002 period. The empirical analysis shows that using a gravity equation derived from theory, in the estimation of the border effect, matters. A representative estimate of the border effect shows that crossing a national border into the OECD countries induces a trade-reduction effect by a factor of 8. This average value masks substantial differences in market access across the country groups considered, with higher value in trade between EU countries and lower in trade between CEEC countries. However, the trade integration between CEECs and others OECDs increases substantially in the...

Accession to the World Trade Organisation: Challenges and Prospects for the Least-developed Countries (LDCs)
Provedor de dados: 31
Autores: Delelegn,   Mussie.
A significant number of countries - many of which are least-developed countries (LDCs) - are not members of the multilateral trading system (MTS) as yet, and for many the accession process has taken an undesirably long period of time to complete. This lack of participation has important implications for national and global policy making in the field of international trade. However, there is a growing tendency to disregard accession challenges and difficulties facing the weakest members of the international community - the LDCs. The main purposes of this article are to a) discuss the substantive, normative and institutional complexities and requirements surrounding the WTO accession process from the perspective of LDCs, b) assess the possible costs and...

Autores: Rodrigues,Paulo Hercílio Viegas; Lima,Ana Maria Liner Pereira; Ambrosano,Gláucia Maria B.; Dutra,Maria de Fátima Batista.
To evaluate the behavior of micropropagated heliconia seedlings during the acclimatization process using different substrates and shade levels, seedlings of H. bihai (Lobster Claw I) were planted in plastic trays using the substrates: washed sand, vermiculite (medium texture), and PlantMax® Horticultura, and shade cloths with percentages of 0% (full sun), 30%, 40%, 50%, 60%, 70%, and 80% of shade in relation to full sun. Best results were obtained for washed sand and PlantMax substrates at shade conditions starting from 50%, especially at 70% and 80%. Pre-existing roots from in vitro rootings were not functional, not presenting secondary roots, and showing root tissue necrosis. Acclimatized seedlings developed new roots. This finding suggests that this...

Accommodating Imperfect Competition in A Model of World Peanut Trade
Provedor de dados: 31
Autores: Fletcher,   Stanley M.; Nadolnyak,   Denis A.
In this paper, we make an attempt to rationalize the strategic behavior of major peanut exporting and importing countries in the framework of imperfectly competitive markets with the focus on the global and inter-American peanut trade. This study is motivated by the fact that liberalizing imperfectly competitive and often distorted markets can have unorthodox effects, in particular increase the incentives to overuse certain trade policies. The results suggest that the South American peanut producers stand to benefit from the reductions in the U.S. peanut production supports but, paradoxically, preservation of a tariff may still be mutually welfare enhancing. In the broader context of global peanut trade, multi-lateral tariff reduction increases the...

Accounting for Neighborhood Influence in Estimating Factors Determining the Adoption of Improved Agricultural Technologies
Provedor de dados: 31
Autores: Langyintuo,   Augustine S.; Mekuria,   Mulugetta.
Researchers have traditionally applied censored regression models to estimate factors influencing farmers'’ decisions to adopt improved technologies for the design of appropriate intervention strategies. The standard Tobit model, commonly used, assumes spatial homogeneity implicitly but the potential for the presence of spatial heterogeneity (spatial autocorrelation or dependence) is high due to neighborhood influence among farmers. Ignoring spatial autocorrelation (if it exists) would result in biased estimates and all inferences based on the model will be incorrect. On the other hand, if spatial dependence is ignored the regression estimates would be inefficient and inferences based on t and F statistics misleading. To account for neighborhood influence,...

Accounting for Uncertainty Affecting Technical Change in an Economic-Climate Model
Provedor de dados: 31
Autores: Bosetti,   Valentina; Drouet,   Laurent.
The key role of technological change in the decline of energy and carbon intensities of aggregate economic activities is widely recognized. This has focused attention on the issue of developing endogenous models for the evolution of technological change. With a few exceptions this is done using a deterministic framework, even though technological change is a dynamic process which is uncertain by nature. Indeed, the two main vectors through which technological change may be conceptualized, learning through R&amp;D investments and learning-by-doing, both evolve and cumulate in a stochastic manner. How misleading are climate strategies designed without accounting for such uncertainty? The main idea underlying the present piece of research is to assess and...

Accumulation of trace metals in some benthic invertebrate and fish species revelant to their concentration in water and sediment of lake qarun, Egypt
Provedor de dados: 20
Autores: Fishar, M.R.A.; Ali, M.H.H.
Concentrations of major metals (Na, K, Ca, Mg) and some trace metals (Fe, Zn, Mn, Ni, Cu, Co, Pb, Cr, Cd) were determined in water, sediment, benthos and some common fish species from Lake Qarun. Water and sediment samples were collected from seven stations where, the benthos and fish species were collected from three sites representing east, middle and west of the lake. Distribution of studied metals showed that, east part generally had higher contamination than west one which may be attributed to the impact of pollution sources in this area which coming from El-Batts Drain and pumping station in the east part. Mollusca and Crustacea especially Barnacles have the highest concentrations of most heavy metals measured more than Polychaeta which make them...

Accuracy assessment of ocean tide models around Antarctica
Provedor de dados: 5
Autores: King, Ma; Padman, L.
Accurate ocean tide models for the circum-Antarctic seas are required to remove unwanted signals from floating ice elevation and space-borne, time-variable gravity measurements ( e. g., GRACE). We present accuracy assessments for several global ( CSR4, FES2004, FES99, GOT00.2, NAO. 99b, TPXO6.2) and Antarctic (CADA00.10 and CATS02.01) ocean tide models using coastal and pelagic tide gauges, gravimetric data and GPS records of ice shelf surface elevation. The accuracies of CSR4 and NAO. 99b are poor in the ice shelf regions. The optimum model for the entire circum-Antarctic seas is TPXO6.2, with a root-mean-square deviation of similar to 5 - 7 cm, similar to 40% lower than the next best model, FES2004. The main exception is the Filchner-Ronne Ice Shelf...

Acephate and methamidophos residues in greenhouse and in field grown tomatoes
Provedor de dados: 75
Autores: Trevizan,Luiz Roberto P.; Baptista,Gilberto C. de; Papa,Geraldo.
Increasing horticultural production under protected cultivation requires more detailed studies about the occurence of pesticide residues, due to the special and peculiar environment under controlled conditions, in which some pests, that are of little concern in the field, become important. The insecticide acephate and its methamidophos metabolite residues were evaluated in greenhouse-grown tomatoes and compared to an open-field tomato crop. The treatments: (a) check; (b) one application of 75 g a.i. acephate.100 L-1 water; (c) one application of 150 g a.i.100 L-1 water; (d) four applications of 75 g a.i.100 L-1 water were evaluated. Fruit, leaf and soil samples were taken at (-1), zero, 1, 3, 7, 14, 21 days after the last or only application. The...

A escassez de dados acerca do comportamento alimentar do camarão marinho Litopenaeus vannamei (Boone, 1931) com relação ao alimento artificial ofertado em bandejas poderá induzir a uma alimentação inadequada, resultando no desperdício da ração, no aporte desnecessário de nutrientes, e conseqüente aumento dos custos com a alimentação e da poluição ambiental potencial desta atividade. Objetivando fornecer subsídios para a melhoria do manejo alimentar praticado nas fazendas, foram realizados estudos comportamentais utilizando 64 juvenis de Litopenaeus vannamei (7,57 ± 1,01g), mantidos em densidade populacional de 33 m², submetidos a fotoperíodo artificial, em ciclo invertido, para observação durante as fases clara e escura.

Utilizando-se dados da Pesquisa Nacional por Amostra de Domicílios (PNAD), de 1998, analisou-se os determinantes da procura por atendimento à saúde devido à doença, nas áreas urbana e rural do Brasil. A variável estado de saúde do indivíduo foi estimada em função de variáveis de infra-estrutura do domicílio, características individuais, renda familiar, etc., e sua estimativa foi utilizada como variável explanatória na equação de procura por atendimento à saúde, para evitar endogeneidade. O fator mais importante na determinação da procura por atendimento à saúde foi o estado de saúde do indivíduo, tanto na área urbana quanto no meio rural. Na área urbana, o nível de escolaridade também teve grande impacto em reduzir a procura por serviços de saúde.

Acetylcholine and bradykinin enhance hypotension and affect the function of remodeled conduit arteries in SHR and SHR treated with nitric oxide donors
Provedor de dados: 56
Autores: Gerová,M.; Kristek,F.; Cacányiová,S.; Cebová,M.
Discrepancy was found between enhanced hypotension and attenuated relaxation of conduit arteries in response to acetylcholine (ACh) and bradykinin (BK) in nitric oxide (NO)-deficient hypertension. The question is whether a similar phenomenon occurs in spontaneously hypertensive rats (SHR) with a different pathogenesis. Wistar rats, SHR, and SHR treated with NO donors [molsidomine (50 mg/kg) or pentaerythritol tetranitrate (100 mg/kg), twice a day, by gavage] were studied. After 6 weeks of treatment systolic blood pressure (BP) was increased significantly in experimental groups. Under anesthesia, the carotid artery was cannulated for BP recording and the jugular vein for drug administration. The iliac artery was used for in vitro studies and determination...

Autores: Fonseca,Adenilson de Souza da; Frydman,Jacques Natan Grinapel; Rocha,Vanessa Câmara da; Bernardo-Filho,Mario.
Acetylsalicylic acid is the drug most used an anti-inflammatory agent and for secondary prevention of thrombotic phenomenon. Drugs can modify the labeling of blood constituents with technetium-99m (99mTc). The aim of this work was to evaluate the effect of in vitro or in vivo assays with acetylsalicylic acid on the labeling of the blood constituents with 99mTc. In vitro assay was performed with samples of whole blood from Wistar rats incubated with acetylsalicylic acid (1.0 mg/ml) for one hour before the 99mTc-labeling process. For in vivo assay, Wistar rats were treated with acetylsalicylic acid (1.5 mg/kg) during one hour, and the whole blood was withdrawn for the 99mTc-labeling process. Saline was used in control groups. Data showed that the fixation of...

Achieving Environmental Objectives Under Reduced Domestic Agricultural Support and Trade Liberalization: An Empirical Application to Taiwan
Provedor de dados: 31
Autores: Chang,   Hung-Hao; Boisvert,   Richard N.; Blandford,   David.
We focus on rice policy reform required for Taiwan's admission to the WTO, and examine the effects, theoretically and empirically, of the re-instrumentation of domestic policy needed to achieve environmental objectives when both positive and negative environmental externalities exist. Policies that treat non-commodity attributes in agriculture as secondary to existing aims, such as income support, are unlikely to result in the desired supplies of environmental goods. Those supplies can be achieved at lower government and social costs using policy instruments to achieve environmental goals directly. Results are relatively insensitive to the social values assigned to environmental goods.

This study focuses on public investments and policy reforms for leveraging growth spillovers at the African regional level. A conceptual framework that is built on the endogenous growth theory and the new economic geography is presented first to gain a better understanding of the underlying theory and empirical evidence on regional integration and growth spillovers. In order to demonstrate the potential benefits from greater cross-border technology spillovers in Africa, as well as from trade liberalization and investment in infrastructure, results from ex-ante simulations using partial and general equilibrium models are then presented and discussed. Results indicate that sizeable regional spillover benefits can be obtained by permitting greater crossborder...

Acoustical estimation of the Antarctic krill swarms spatial distribution and biomass
Provedor de dados: 13
Autores: Tokarev, Yu. N.; Vasilenko, V. I.; Zhuk, V. F.; Sokolov, V. G.; Slipetsky, D. Ya.
The method of acoustic express-evaluation of the krill (Euphausia superba Dana) population spatial structure and determination of its accumulations biomass, with 80 kHz echosounding frequencies has been worked out during the 7-th Ukrainian Antarctic expedition. The method error does not exceed 10 %, which permits to recommend it for usage under the Antarctic krill fishery conditions. The principal possibility to acoustically express-evaluate chorological structure of the Antarctic krill population has been shown. Formation by krill of dense accumulations of different form, elongated for 6 miles, appeared to be an expressed feature of krill behaviour during observations. The school type in krill distribution was observed as well. Parallel to this the...

Acquisition of the neodymium isotopic composition of the North Atlantic Deep Water
Provedor de dados: 5
Autores: Lacan, F; Jeandel, C.
The North Atlantic Deep Water (NADW) neodymium isotopic composition (Nd IC) is increasingly used in oceanography and paleoceanography to trace large-scale circulation and weathering processes, notably to investigate past variations of the global thermohaline circulation. Although the present-day NADW Nd IC is well characterized at epsilon(Nd) = - 13.5, the acquisition of this isotopic signature ( in other words, the causes of this value) has so far been very sparsely documented. Such an understanding is, however, fundamental to the interpretation of paleo records. Nd IC and rare earth element concentrations were measured at 9 stations within the North Atlantic Subpolar Gyre ( SIGNATURE cruise, summer 1999). The comparison of this data set with our...

Acreage Abandonment, Moral Hazard and Crop Insurance
Provedor de dados: 31
Autores: Chen,   Shu-Ling.
Empirical evidence for the existence of moral hazard in the U.S. crop insurance program has been inconclusive.  Here we use a nested-dynamic programming framework to estimate an intra-seasonal dynamic model that explicitly incorporates a farmer's crop abandonment decision.  The estimation is implemented for selected Texas counties where actuarial performances of the crop insurance program are poor and high incidences of acreage abandonment are frequently observed.

Infection by unusual microorganisms can be one of the clinical manifestations of primary immunodeficiency (PID). We report on a four-month-old child with pneumonia caused by the fungus Acremonium kiliense as the first clinical manifestation of chronic granulomatous disease. We emphasize the importance of an active search for unusual organisms in immunodeficient patients, and a precise diagnosis and early institution of specific treatment against such microorganisms for the reduction of the morbidity and mortality of these patients.

Provedor de dados: 58
Autores: Grisi,Teresa Cristina S. de Lima; Gorlach-Lira,Krystyna.
The aim of this study was to evaluate the potential of nisin and high pH to inhibit the growth of Staphylococcus aureus and Salmonella sp. in broth culture and when inoculated into meat of land crab. In pure cultures, the growth of S. aureus was bly inhibited by nisin and the growth of Salmonella sp. was inhibited by nisin-EDTA (20 mM). The inhibition of S. aureus lasted for eight hours and Salmonella sp. growth was inhibited throughout the experiment (24 h). The high pH (pH 10.0 and 11.0 with NaHCO3-NaOH buffer) was very effective for in vitro inhibition of S. aureus and Salmonella sp. Nisin and high pH, when applied to the contaminated meat, did not yield the same effect. Nisin was not effective in preventing growth of both pathogens in the crab meat,...

Activation of a P2Y4-like purinoceptor triggers an increase in cytosolic [Ca2+] in the red blood cells of the lizard Ameiva ameiva (Squamata, Teiidae)
Provedor de dados: 56
Autores: Sartorello,R.; Garcia,C.R.S.
An increasing number of pathophysiological roles for purinoceptors are emerging, some of which have therapeutic potential. Erythrocytes are an important source of purines, which can be released under physiological and physiopathological conditions, acting on purinergic receptors associated with the same cell or with neighboring cells. Few studies have been conducted on lizards, and have been limited to ATP agonist itself. We have previously shown that the red blood cells (RBCs) of the lizard Ameiva ameiva store Ca2+ in the endoplasmic reticulum (ER) and that the purinergic agonist ATP triggers a rapid and transient increase of [Ca2+]c by mobilization of the cation from internal stores. We also reported the ability of the second messenger IP3 to discharge...

Active thrust faulting offshore Boumerdes, Algeria, and its relations to the 2003 Mw 6.9 earthquake - art. no. L043111
Provedor de dados: 5

[1] We investigate the active seismogenic fault system in the area of the 2003 Mw 6.9 Boumerdes earthquake, Algeria, from a high-resolution swath bathymetry and seismic survey. A series of 5 main fault-propagation folds similar to20-35 km long leave prominent cumulative escarpments on the steep slope and in the deep basin. Fault activity creates Plio-Quaternary growth strata within uplifted areas such as a rollover basin on the slope and piggyback basins in the deep ocean. Most thrusts turn to fault-propagation folds at the sub-surface and depict ramp-flat trajectories. We find that the two main slip patches of the 2003 Mw 6.9 Boumerdes earthquake are spatially correlated to two segmented cumulative scarps recognized on the slope and at the foot of the...

Acute effects of selective serotonin reuptake inhibitors on neuroleptic-induced catalepsy in mice
Provedor de dados: 56
Autores: Pires,J.G.P.; Bonikovski,V.; Futuro-Neto,H.A.
Depression found in Parkinson disease (PD) usually responds to selective serotonin reuptake inhibitors (SSRIs). Drugs that modify experimental neuroleptic catalepsy (NC) might affect extrapyramidal symptoms in PD. Therefore, the effects of SSRIs on NC were tested in mice, 26-36 g, separated by sex. Catalepsy was induced with haloperidol (H; 1 mg/kg, ip) and measured at 30-min intervals using a bar test. An SSRI (sertraline, ST; paroxetine, PX; fluoxetine) or vehicle (C) was injected ip 30 min before H. Dunnett's test was used for comparison of means. ST (1-5 mg/kg) or PX (1-5 mg/kg) attenuated NC, with a similar inhibition found in both sexes (5 mg/kg, 180 min: ST - males: 124 ± 10 vs 714 ± 15 s in C; females: 116 ± 10 vs 718 ± 6 s in C; PX - males: 106 ±...

Acute respiratory distress syndrome due to vivax malaria: case report and literature review
Provedor de dados: 55
Autores: Lomar,André V.; Vidal,José E.; Lomar,Frederico P.; Barbas,Carmen Valente; Matos,Gustavo Janot de; Boulos,Marcos.
Severe pulmonary involvement in malaria has been frequently reported in cases of Plasmodium falciparum infection, but rarely in vivax malaria. Among the 11 previous cases of vivax-related severe respiratory involvement described in the literature, all except one developed it after the beginning of anti-malarial treatment; these appear to correspond to an exacerbation of the inflammatory response. We report the case of a 43-year-old Brazilian woman living in a malaria-endemic area, who presented acute respiratory distress syndrome (ARDS) caused by P. vivax before starting anti-malarial treatment. The diagnosis was made based on microscopic methods. A negative rapid immunochromatographic assay, based on the detection of Histidine Rich Protein-2 (HRP-2) of P....

Adjusting Monetary Measures of Poverty to Non-Monetary Aspects: An Analysis Based on Sri Lankan Data
Provedor de dados: 31
Autores: Weerahewa,   Jeevika; Wickramasinghe,   Kanchana.
This paper reassesses the status of poverty in Sri Lanka using a monetary measure which was adjusted for people's perceptions about the social climate.  Data collected by the Sri Lanka Integrated Survey was used to obtain incidences of poverty using cost of basic need (CBN) poverty lines and poverty lines adjusted for people's perceptions.  The results reveal that the poverty measurements significantly differ with the two approaches though poverty ranking remains more or less consistent.

Effekten av tre ulike konserveringsmetoder for bygg på fôropptak og melkekvalitet i økologisk landbruk ble testet i et fôringsforsøk med cross over design med tre perioder á en uke. Kyrne ble tildelt 6,0 kg TS (førstekalvskyr 5,0 kg TS) av enten tørket bygg (Arve), valset bygg ensilert med melasse, eller valset bygg ensilert med syrer. I tillegg til bygg ble kyrne tildelt grassurfôr ad libitum og en mineral/vitamin-blanding. Forsøket ble gjennomført i Bodø i mars 2004.  Alle de tre metodene konserverte bygget godt. Konserveringsmetoden hadde ingen innvirkning på det totale fôropptaket. Kyrne var i sen laktasjon og melkeproduksjonen var lav, men det var ingen forskjell i ytelse mellom konserveringsmetodene for bygg. Innholdet av råprotein var lavt i...

Adopting New Zealand Dairy Farm Principles and Practices in Argentina
Provedor de dados: 31
Autores: Peluffo,   Matias; Shadbolt,   Nicola M.
The dairy sector is important to Argentina because it creates genuine wealth and employment. Milk production at competitive costs is crucial for the endurance of the Argentine dairy sector; therefore the development of competitive dairy farm systems is important for Argentina. New Zealand (hereafter NZ) dairy farm systems are internationally known for their competitiveness without the presence of subsidies. Though Argentine dairy farmers have been attracted to NZ systems for more than 40 years and despite the fact that the NZ knowledge appears to be beneficial to Argentine farms, NZ practices have been rarely adopted. This seemingly fruitless effort in extending this technology shapes the research question of the present study: Can Argentine dairy farmers...

Adoption Behavior in Food Retailers' Decision to Offer Fresh Irradiated Ground Beef
Provedor de dados: 31
Autores: Jaenicke,   Edward C.; Harrison,   R. Wes; Jensen,   Kimberly L.; Jakus,   Paul M.
During the 14-month period from May 2002 to June 2003, approximately 10 percent of U.S. supermarkets began to offer fresh irradiated ground beef under the stores' own labels. Using a survey of supermarket store managers from this time period, this paper investigates the factors that influenced stores' adoption of irradiated ground beef. Results from the adoption model show that factors associated with competition, merchandising philosophy, and structure in the food retailing industry play a strong role in the decision. Among other results, we find that variables relating to a competitor's adoption status and proximity can increase the likelihood of a store's adoption decision.

Adoption of Certified Organic Production: Evidence from Mexico
Provedor de dados: 21
Autores: Hattam, Caroline E.; Holloway, Garth J.
Adoption of organic production and subsequent entry into the organic market is examined using Mexican avocado producers as a case study. Probit analysis of a sample of 183 small-scale (&lt;15ha) producers from Michoacán suggests that adoption is positively influenced by management and economic factors (e.g. production costs per hectare and making inputs), but also by social factors (e.g. membership of a producers’ association). Experience in agriculture has a significant but negative effect. Effective policy design must be therefore be aware of both the economic and social complexities surrounding adoption decisions.

Adoption of Clean Leather-Tanning Technologies in Mexico
Provedor de dados: 31
Autores: Blackman,   Allen.
In many developing countries, a host of financial, institutional, and political factors hamstring conventional environmental regulation. Given these constraints, a promising strategy for controlling pollution is to promote the voluntary adoption of clean technologies. Although this strategy has received considerable attention in policy circles, empirical research on the adoption of clean technologies in developing countries is limited. This paper presents historical background and original survey data on the adoption of five clean tanning technologies by a sample of 137 leather tanneries in Leon, Guanajuato, Mexico, a city where tanneries have serious environmental impacts and conventional environmental regulation has repeatedly failed to mitigate the...

Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related.  Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis.  Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

The adoption of environmental management practices is addressed in this paper. The use of consumer behaviour theory and a market research approach is discussed by describing how it was used in the study. Qualitative methods were used to gather data from dairy farmers in four New Zealand catchments. The environmental practices explored were; excluding stock from waterways, reducing phosphorus use, improving soil macroporosity, managing effluent and improving the efficiency of border-dyke irrigation. The findings are discussed, highlighting that farm contextual factors influenced farmers’ decision making in terms of adopting environmental management practices. The results suggest that environmental practices need to be linked to farm context. This should...

Adoption of Integrated Pest Management Technologies: A Case Study of Potato Farmers in Carchi, Ecuador
Provedor de dados: 31
Autores: Barrera,   Victor; Norton,   George W.; Alwang,   Jeffrey Roger; Mauceri,   Maria.
Agricultural development is essential for improved well-being in rural Ecuador.  As much as 40% of the population relies on agriculture as its primary source of income and agricultural exports account for a significant proportion of foreign exchange revenue.  In the highlands, potatoes are a major staple, and more than 90,000 producers grow them on about 60,000 hectares of land.  Potato production is associated with heavy use of chemical inputs--pesticides and fertilizers--to manage pests and optimize profits. Concerns have emerged about the sustainability of Ecuador's potato crop as rising input costs have created a cost squeeze and public health officials are increasingly concerned about health consequences of pesticide over use.  Producers need...

Autores: Henderson,   Jason R.; Dooley,   Frank J.; Akridge,   Jay T.; Carerre,   Antonio.
This paper explores the factors guiding Internet adoption by agribusiness firms. The relationship between Internet strategies and manager perceptions on the barriers to and catalysts for Internet adoption are analyzed in a supply-chain management framework. Using factor analysis and an ordered Probit model, results indicate that Internet strategies are more likely to be adopted in larger firms with a global scope. Also, manager perceptions regarding the impact of Internet adoption on transaction costs are just as likely to influence adoption as the perceived impacts on more traditional production costs.

Adoption of Soil Conservation Practices in Olive Groves: The Case of Spanish Mountainous Areas
Provedor de dados: 31
Autores: Calatrava-Leyva,   Javier; Franco,   Juan Agustin; Gonzalez-Roa,   Maria del Carmen.
This paper presents some results from a survey carried out in 2004 among 223 olive tree farmers from mountainous areas in the Spanish Southern provinces of Granada and Jaen regarding the adoption of soil conservation and management practices. Olive tree groves in mountainous areas are subject to a high risk of soil erosion and have to incur in higher costs of soil conservation. This results in greater difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil...

Provedor de dados: 64
Autores: Rezende,Pedro Milanez de; Gris,Cristiane Fortes; Carvalho,Janice Guedes; Gomes,Leonardo Lino; Bottino,Luiz.
A busca de novas alternativas para o aumento da produtividade da soja tem sido constante objetivo de pesquisadores e produtores. As respostas da cultura à aplicação do fósforo via solo são bem definidas, sendo esse nutriente de grande importância no desenvolvimento da mesma, implicando seu uso em aumento do rendimento. A adubação foliar nessa cultura vem sendo muito difundida por empresas deste ramo, surgindo como uma opção viável de fornecimento suplementar de nutrientes, principalmente quando constatados níveis baixos na planta em caso de deficiências. Visando dar maiores subsídios aos produtores, objetivou-se com este trabalho estudar o efeito da adubação foliar de fósforo aplicado em diferentes estádios da planta compreendendo: V5, R1, R4, V5+R1,...

Nuclear medicine is a powerful diagnostic technique able to detect inflammatory foci in human disease. A wide range of agents have been evaluated for their ability to distinguish lesions due to microbial infection from those due to sterile inflammation. Advances continue to be made on the use of radiolabelled antibiotics which as well as being highly specific in the diagnosis of infection may be useful in monitoring the treatment and course of disease. Here we provide an update on in-vitro and clinical studies with a number of established and novel radiopharmaceuticals

Advances in the artificial feeding of Ornithodoros moubata (Acari: Ixodidae) and the follow up of its life cycle after feeding on fetal bovine serum
Provedor de dados: 19
Autores: Ruheta, Martin R.; Inoue, Noboru; Fujisaki, Kozo.
Ornithodoros moubata was fed artificially through a parafilm membrane with two types of artificial meals. The first type was composed of bovine and horse red blood cells suspended in phosphate buffered saline or fetal bovine serum (FBS). The second type was composed of FBS alone. Engorgement and post engorgement survival rates of the ticks after feeding on the two types of meals were compared and analysed statistically. FBS was found to be superior to red blood cell meals. Eventually two batches of FBS from different manufacturers were used to feed the ticks through artificial membrane. Engorgement and post engorgement survival rates were again compared and analysed statistically. There was no significant difference between the two lots. Finally O. moubata...

Advances in weed management for organic cereal production in southeast Australia
Provedor de dados: 21
Autores: Burnett, Viv; Enshaw, Tim; Sutherland, Steve.
Organic cereal production in southeast Australia is challenging for producers due to a range of e of influences such as weeds and low soil available phosphorus. Two experiments were conducted on a certified organic property at Berrigan NSW during 2001-2003 to investigate ‘within crop’ weed management and forage crop management for weed control. Sowing later using a short season wheat cultivar did not affect yield and reduced (P&lt;0.05) levels of annual ryegrass (Lolium rigidum Gaud.). Incorporating a forage crop into the rotation prior to sowing a cereal resulted in improved (P&lt;0.05) weed management for the cereal crop, in comparison to retaining annual pasture. There were no differences between forage treatments in weed management in the following...

Aerial and snorkelling census techniques for estimating green turtle abundance on foraging areas: A pilot study in Mayotte Island (Indian Ocean)
Provedor de dados: 5
Autores: Roos, David; Pelletier, Dominique; Ciccione, Stéphane; Taquet, Marc; Hughes, George.
Monitoring the abundance of green turtles (Chelonia mydas) is necessary to assess population trends and risks of collapse. This note presents a study aimed at comparing three techniques for the direct estimation of green turtle numbers in their foraging habitats (seagrass beds and reef flats). The experiment was carried out at Mayotte Island, Western Indian Ocean. The techniques involved were surveys by snorkel, and aerial surveys using a microlight aircraft and a paramotor. Each technique had shortcomings and advantages. While each technique provided estimations of turtle numbers only surveys by snorkel permitted identification of species and sex, whenever visibility and turtle behaviour permitted. Along the shorelines, and over foraging areas, the...

Ærter som kvælstofsamler i vinterafgrøder
Provedor de dados: 21
Autores: Vinther, F.P.
I markforsøg blev det undersøgt hvorvidt samtidig såning af ærter og vinterkorn kunne øge kerneudbytter i kornet. Princippet i dyrkningsmetoden  er at ærterne i løbet af efteråret via biologisk N-binding optager luftens kvælstof, som efter ærternes udvintring friggives til kornafgrøden i det tidlige forår. Sammenfattende kunne det konkluderes, at såfremt der ikke er større udgifter forbundet med anskaffelse af ærteudsæd (evt. ærter af egen avl), kan dyrkningssystemet med fordel anvendes. Specielt i år hvor de klimatiske forhold gør det vanskeligt at udbringe gødning tidligt, vil ”ærte-kvælstof” kunne sikre at kornafgrøden kommer godt i gang.

AFLP markers differentiate isolates of Colletotrichum gossypii from C. gossypii var. cephalosporioides
Provedor de dados: 102
Autores: Silva-Mann,Renata; Vieira,Maria G. G. Carvalho; Machado,José C.; Bernardino Filho,José Roberto; Salgado,Kalinka C. C.; Stevens,Mikel R.
Fungal diseases in cotton (Gossypium hirsutum), such as anthracnose caused by Colletotrichum gossypii and ramulose caused by C. gossypii var. cephalosporioides, are responsible for large yield losses. These pathogens are seed borne and morphologically similar although they induce different symptoms, which can lead to misdiagnosis using the blotter testing method. The present study was carried out to assess the viability of using Amplified Fragment Length Polymorphism (AFLP) markers to differentiate these pathogens. Five isolates, for each pathogen, were classified according to pathogenicity on cotton plants, and mycelial growth morphology. Conidial suspensions were sprayed on 30-day-old cotton plants and the symptoms assessed ten and 40 days after...

Africa Without borders: Building Blocks For Regional Growth
Provedor de dados: 31
Heavy investment in many aspects of development is needed to bring Africa into the world economy. With a large share of their populations living and working in the rural economy, many African governments are emphasizing the agricultural sector in their strategies for economic growth, poverty reduction, and food security. A growing commitment to market-oriented agricultural growth is reflected in numerous high-level government statements as well as in the Comprehensive Africa Agriculture Development Programme (CAADP) of the New Partnership for Africa’s Development (NEPAD). Although many investments in agricultural growth are necessarily country-focused, there are economic reasons for African countries to coordinate and cofinance some of these efforts. The...

After the Bubble: The Survival and Ownership of Internet Marketplaces for Farmers and Agribusiness
Provedor de dados: 31
Autores: Wheatley,   W. Parker; Buhr,   Brian L.
This paper presents a theory of how industry structure and beliefs about Internet marketplace use have driven choice and ownership of marketplaces. The theory's predictions suggest that surviving Internet marketplaces will be those with strong historical linkages in an industry and those owned by or affiliated with major commodity buyers. Comparisons of these predictions with actual outcomes provide validation of the theory. Where predictions differ from results, observations are made as to the nature of the deviations.

The anatomical characteristics observed allowed us to classify this specimen as a new member of the genus Agathoxylon : A . matildense n. sp. Distinct growth rings are observed in transversal sections while radial views show uniseriate tracheid pitting, contiguous and predominantly circular in shape, cross-fields are cupressoid with 4-5 pits irregularly arranged. Rays are homogeneous and very low (1-4 cells hight). Wood characters, its relationships with living related taxa and the associated fossil flora allow us to consider this wood as an Araucariaceae member. Agathoxylon matildense n. sp. probably grew under...

Age, Health, and the Willingness to Pay for Mortality Risk Reductions: A Contingent Valuation Survey in Japan
Provedor de dados: 31
Autores: Itaoka,   Kenshi; Krupnick,   Alan J.; Akai,   Makoto; Alberini,   Anna; Cropper,   Maureen L.; Simon,   Nathalie B.
A contingent valuation survey was conducted in Sizuoka, Japan, to estimate the willingness to pay (WTP) for reductions in the risk of dying and calculate the value of statistical life (VSL) for use in environmental policy in Japan. Special attention was devoted to the effects of age and health characteristics on WTP. We find that the VSLs are somewhat lower (103 to 344 million yen) than those found in the virtually identical survey applied in some developed countries. These values were subject to a variety of validity tests, which they generally passed. We find that the WTP for those over age 70 is lower than that for younger adults, but that this effect is eliminated in multiple regression. Rather, when accounting for other covariates, we find that WTP...

Autores: Gonçalves,Paulo de Souza; Bortoletto,Nelson; Cardinal,Átila Bento Beleti; Gouvêa,Lígia Regina Lima; Costa,Reginaldo Brito da; Moraes,Mário Luiz Teixeira de.
In a field trial involving 68 rubber tree (Hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth A and for age 7 to 12 (mature period) for girth B and for age 7 to 12 (production of latex) for yield. Rank correlation coefficients between all immature ages of girth (girth A), all ages of mature girth (girth B) and all annual rubber production (yield) were significant for the three traits, with the coefficients decreasing with increasing age. Selection of the sets of best 30, 15, 10 and 5 clones from the available 68 clones at a given age was generally accompanied by a descending order of percentage success. It was suggested: (a) to have the best 30 clones of...

Agent-Based Modelling and Sensitivity Analysis by Experimental Design and Metamodelling: An Application to Modelling Regional Structural Change
Provedor de dados: 31
Autores: Happe,   Kathrin.
This paper presents the application of the sensitivity analysis techniques Design of Experiments (DOE) and metamodelling to the agent-based model AgriPoliS, which is a spatial and dynamic simulation model of regional structural change. DOE and metamodelling provide a more systematic analysis of results of complex simulation models. When summarising the results, it becomes clear that interest rates, technical change and managerial ability influence average economic land rent the most.

Autores: Akram Al-Motabagani,Mohamed.
Disturbances of the urinary bladder functions are common in the elderly people particularly women. So, it was the aim of the present work to detect the age-associated changes in the urinary bladder that might play a role in the bladder dysfunctions. Twenty albino rats were used in the present work. They were divided into two equal groups, each consisted of ten rats. The first group included the adult rats (aged 3 months) and served as control group, while the second group was the senile rats (aged 24 months). Specimens of the urinary bladder were taken, processed and examined using the light microscope (LM) and the scanning electron microscope (SEM). Light microscopic examination of the urinary bladder of the aged rats showed marked mucosal damage, ranging...

Agglomeration, Spatial Interaction and Convergence in the EU
Provedor de dados: 31
Autores: Brauninger,   Michael; Niebuhr,   Annekatrin.
We investigate the convergence process among EU regions between 1980-2002 taking into account the effects of spatial heterogeneity and spatial spillover effects. The spatial regimes model allows for different steady-state growth paths. In contrast to previous analyses, the regimes in this paper refer to spatial categories, i.e. we assume that agglomerations, urbanised and rural regions are characterised by group-specific steadystates. Moreover, the regression analysis considers the effects of interaction among neighbouring regions, possibly leading to a spatial dependence of regional growth rates. We check whether spatial dependence is caused by spatial spillovers or based on country effects.

Autores: Feleke,   Shiferaw T.; Liu,   Hongyan.
We provide estimates of expenditure and price elasticities of the demand for imported milk in Spain using a dynamic Linear Approximate of the Almost Ideal Demand System (LA-AIDS).  We also provide evidence of structural change in the demand for imported milk in Spain due to the dairy program established in 1966 and Spain's accession into the EU in 1986.  Results have important implications for the EU in terms of demand forecasting, welfare analysis, and resource allocation to design an effective production and supply plan.

Aggregation and Calibration of Agricultural Sector Models Through Crop Mix Restrictions and Marginal Profit Adjustments
Provedor de dados: 31
Autores: Wiborg,   Torben; McCarl,   Bruce A.; Rasmussen,   Svend; Schneider,   Uwe A.
All agricultural sector models must deal with aggregation and calibration somehow. The aggregation problem involves treating a group of producers as if they all responded in the same way as a single representative unit. The calibration problem concerns making a model reproduce as closely as possible an empirically observed set of decision maker actions. This paper shows how both calibration and aggregation are addressed through crop mix restrictions combined with marginal profit adjust-ments.

Aggregation Theory for Incomplete Systems
Provedor de dados: 31
Autores: LaFrance,   Jeffrey T.; Beatty,   Timothy K.M.; Pope,   Rulon D.
Gorman's theory of demand is extended comprehensively to incomplete systems. The incomplete systems approach dramatically increases this class of models. The separate roles of symmetry and adding up are identified in the rank and the functional form of this class of models. We show that symmetry determines rank and the maximum rank is three. We show that adding up and 0o homogeneity determines the functional form and there is no functional form restriction for an incomplete system. We prove that every full rank system and reduced rank systems with a minimal level of degeneracy can be written as a polynomial in a single function of income. A complete set of closed form solutions for the indirect objective functions of this class of models is derived. A...

The recent CAP reform introduced new income support instruments much more related on agricultural agents land-use and land-ownership conditions than before.  In this perspective the behavioural analysis of land-use and land-ownership decision process seems to be a basic condition to evaluate the efficiency, effectiveness and equity of those instruments, and to understand and to forecast the agents response to these stimuli.  The land-use and land-ownership behaviour differs according to various land managers, not only on the base of "economic-productive" conditions, but also on the base of exogenous and endogenous "institutional" conditions, such as the presence of formal or informal contracts, cultural values, intergenerational linkages, family-farm...

We examine some characteristics of agricultural and rural cooperatives and their management challenges, in order to illustrate possible applications of Jim Collin’s management concept, catalytic mechanisms, in the cooperative context. Agricultural cooperatives are experiencing complex governance issues, particularly in light of increased heterogeneity of member interests, and increased market and regulatory pressures. Member commitment is often recognized to be a necessary ingredient in the cooperative success, and while primary agricultural cooperatives are built on that commitment, new generation cooperatives need not be. In this article we argue that some of the governance issues may be alleviated by the application of creating catalytic mechanisms, a...

Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to the existence of a hypoxic, or "dead", zone in the Gulf of Mexico.  Focusing on two small agricultural watersheds in southwestern Minnesota, simulation results from the Agricultural Drainage And Pesticide Management (ADAPT) model were combined with a linear-optimization model to evaluate the environmental and economic impact of alternative land-use policies for reducing nitrogen losses.  Of particular importance was the study's explicit focus on agricultural subsurface (tile) drainage, which has been identified as the major pathway for agricultural nitrogen losses in the upper Midwest, and the use of drainage-focused abatement policies....

Agricultural Economics Education in Ukrainian Agricultural Universities: An Efficiency Analysis Using Data Envelopment Analysis
Provedor de dados: 31
Autores: Lissitsa,   Alexej; Coelli,   Tim J.; Rao,   D.S. Prasada.
Ukraine's transition from a centrally-planned to a market economy has had a profound effect upon its agricultural sector and agricultural universities. A substantial reduction in state financing has forced universities to adopt a range of survival strategies, with varying degrees of success. In this paper we use data envelopment analysis to examine the technical efficiency of 44 agricultural economics programs from 19 Ukrainian universities during the 2002/03 academic year. Our empirical results indicate wide disparities in performance, ranging from 36% to 100% technical efficiency. A second-stage analysis suggests that factors such as student demand, commercial activities and staff quality help explain a portion of this variation.

Agricultural Extension for the Invisible Actors in Hunger Drama in Rural Nigeria
Provedor de dados: 31
Autores: Egbuna,   Ngozi.
It is now an undisputable fact that rural women farmers produce more than half of all the food grown in Nigeria. They are mainly responsibility for providing food for their families as they plant, harvest and fish, gather fuel wood, fetch water, cook as well as process and sell foodstuffs. This paper describes them as invisible actors in the hunger drama because though they feed the nation, they have little or no access to factors of production that boost productivity such as extension services. Indeed, while the dominance of women in rural areas are evident, policy makers, planners and extension officials often behave as if women did not exist, as if the situation and needs of all farmers were the same, whether men or women. Agricultural extension is one...

From production to retail, information systems have become increasingly important in the agrifood system.  Retailers use information systems to improve inventory management and increase efficiency in production and logistics.  Innovations in agribiotechnology and food safety issues highlighted by incidences related to Starlink corn and “mad cow disease” have raised consumer concerns about their food products.  In addition to food safety concerns, consumers are increasingly willing to pay premiums for nonobservable quality characteristics in their food products.

Since the early 1990s, India has undergone substantial economic policy reform and economic growth. Though reforms in agricultural policy have lagged those in other sectors, they have nonetheless created a somewhat more open economic orientation. In this study, we evaluate the protection and support versus disprotection of agriculture in India. Our methodology involves examining market price support (MPS) for eleven crops, the expenditures on input subsidies benefiting farmers (for fertilizer, electricity and irrigation), and product-specific and total producer support estimates (PSEs) over the period 1985-2002. We draw on the extensive price-comparison and subsidy-measurement data sets and analysis developed earlier by Gulati and his co-authors, often...

Agricultural Production with Change and Uncertainty: A Temporal Case Study Simulation of Colorado Potato Beetle
Provedor de dados: 31
Autores: Heikkila,   Jaakko; Peltola,   Jukka.
Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive agricultural pest, Colorado potato beetle, and agricultural production in Finland. Invasions are modelled as temporally random events and stochasticity in key variables is built into the analysis. The viability of two specific policy options is evaluated given uncertainty and local change.

Mathematical programming methods are widely used for modelling farmers' decision-making and for economic analysis in agriculture.  In this study, a MOTAD risk-programming model is applied to study the effects of risk on cropping pattern and farmers' income in Ramjerd and Sarpaniran districts near Marvdasht in the Fars Province of Iran.  Primary data from 194 farmers randomly selected from 31 villages are used in this study.  The results indicate that variability of crops gross margins or outcomes has a significant effect on cropping pattern but it varies over different farmers and regions with various conditions.  Moreover, it was found that farm plans with more number of crops have a lower return but high degree of certainty.  Based on this research,...

Agricultural Risk Management - Experiences from an Action Research Approach
Provedor de dados: 31
Autores: Lund,   Mogens; Oksen,   Arne; Larsen,   Torben Ulf; Andersen,   Henning.
A new model for risk management in agriculture is described in the paper. The risk model is constructed as a context dependent process, which includes four main phases. The model is aimed at agricultural advisors, who wish to facilitate and disseminate risk management to farmers. It is developed and tested by an action research approach in an attempt to make risk management more applicable on family farms. Our obtained experiences indicate that farmers don't apply probabilistic thinking and other concepts according to formal decision theory.

Agricultural science and technology policy for growth and poverty reduction
Provedor de dados: 31
Autores: Omamo,   Steven Were; Naseem,   Anwar.
This paper argues that the largely unrealized potential of agricultural science and technology (S&amp;T) in promoting growth and poverty reduction in developing countries results from deeply rooted incompatibility among policy environments, institutional arrangements, and micro conditions and behavior in agricultural research and development (R&amp;D). Achieving growth and poverty reduction based on greater agricultural productivity therefore means achieving greater compatibility among these three dimensions of agricultural innovation systems. Research is sorely needed to build understanding of (1) the “big picture” influencing agricultural S&amp;T policy design and implementation in developing countries, (2) strategies for sustainable funding and delivery...

Agricultural Tariff Rate Quotas: Impacts on Market Access
Provedor de dados: 31
Autores: Li,   Xianghong; Carter,   Colin A.
We study the impacts of the implementation of agricultural tariff rate quotas on market access. A doble-censored Tobit model is specified to examine factors that affect the performance of tariff rate quotas. The results show that both in-quota tariff rates and administrative methods restrict market access and lower quota fill rate. The effect of over-quota tariff, however, is insignificant during the study period.

Agricultural technology, productivity and employment: Policies for poverty reduction
Provedor de dados: 31
Autores: Thirtle,   Colin G.; Piesse,   Jenifer; Gouse,   Marnus.
This paper begins by arguing that agricultural economics has an important contribution to make to the economic transition of the new democratic South Africa. Policies are required to reduce unemployment, poverty and inequality, but does the work of agricultural economists provide the policy makers with the information necessary to make the correct choices?  In this context, we update our recent work on technology, efficiency and productivity in South African agriculture, for both the commercial and smallholder sub-sectors. For the commercial sector, this means extending the total factor productivity index and estimates of the demand for labour. For the smallholder sector, there are new results on the impacts of GM cotton and white maize on output and...

Agricultural Trade Liberalisation and Strategic Environmental Policy
Provedor de dados: 31
Autores: Glebe,   Thilo W.; Latacz-Lohmann,   Uwe.
We use an extended partial equilibrium trade model to derive optimal environmental policy responses to tariff reduction requirements and assess the impact of such policies on the welfare of trading partners. We find that countries which attribute preferential political weights to farmers' welfare have an incentive to implement environmental policies that deviate from the Pigouvian solution - even if production is not de facto linked to environmental externalities. We clarify the conditions under which trading partners do not gain from unilateral trade liberalisation if trade concessions are accompanied by strategic environmental policy changes. We postulate a role for the WTO in overseeing the process of domestic policy formulation.

Agricultural trade liberalisation in the Doha Round: impacts on Spain
Provedor de dados: 31
Autores: Philippidis,   George.
Whilst there is a growing literature of computable general equilibrium (CGE) studies examining the impacts of the current Doha Proposals, estimates for the EU are highly aggregated (i.e., EU15). Employing a detailed baseline scenario and a plausible Doha outcome, we examine the long run costs for the European Union, in particular focusing on Spain. Moreover, we implement recent CAP reforms through explicitly modelling of CAP mechanisms to provide greater credibility in assessing the long run asymmetric budgetary and welfare impacts on EU member states. Our estimates forecast resource substitution effects between Spanish agro-food sectors and resource shifts from agro-food activities into manufacturing and services production. In Spain, the impacts of...

Agricultural Trade Liberalization and Greenhouse Gas Emissions: Modeling the Linkages Using a Partial Equilibrium Trade Model
Provedor de dados: 31
Autores: Saunders,   Caroline M.; Wreford,   Anita.
Global attempts to limit greenhouse gas (GHG) emissions may impact on agricultural trade and producer returns, particularly in countries such as New Zealand, where a relatively large proportion of GHG emissions originate from the agricultural sector. This study uses an extended partial equilibrium agricultural trade model to analyze the effects of trade policy liberalization on agricultural production and trade, as well as on GHG emissions. Further analysis combines trade liberalization with GHG mitigation policy in the New Zealand and European dairy sectors, and the effects on producer returns and GHG emissions are predicted. As expected, full trade liberalization in the OECD (Organization for Economic Cooperation and Development) countries enhances...

Agricultural Trade Liberalization: Assessing the Consequences for Developing Countries
Provedor de dados: 31
Autores: Bureau,   Jean-Christophe; Jean,   Sebastien; Matthews,   Alan.
Recent analyses suggest that the impact of agricultural trade liberalization on developing countries will be very uneven. Simulations suggest that the effects of agricultural trade liberalization will be small, overall, and are likely to be negative for a significant number of developing countries. The Doha Round focuses on tariff issues, but these countries currently have practically duty-free access to European and North American markets under preferential regimes. Multilateral liberalization will erode the benefits of these preferences, which are presently rather well utilized in the agricultural sector. The main obstacles to the exports of the poorest countries appear to be in the non-tariff area (sanitary, phytosanitary standards) which increasingly...

Agricultural Trade Preferences and the Developing Countries
Provedor de dados: 31
Autores: Wainio,   John; Shapouri,   Shahla; Trueblood,   Michael A.; Gibson,   Paul R.
Nonreciprocal trade preference programs originated in the 1970s under the Generalized System of Preferences (GSP) as an effort by high-income developed countries to provide tariff concessions for low-income countries. The goal of the programs was to increase export earnings, promote industrialization, and stimulate economic growth in the lower income countries. This study analyzes detailed trade and tariff data for the United States and the European Union (the two largest nonreciprocal preference donors) to determine the extent to which the programs have increased exports from beneficiary countries. For those products where the margins of preference are large and where beneficiaries have a comparative advantage and the capacity to expand production, these...

Agricultural transformation: Lessons from experience
Provedor de dados: 31
Autores: Swinnen,   Johan F.M.
It is now fifteen years ago that the Berlin Wall fell, the start of a vast set of changes throughout the countries of Eastern Europe and the former Soviet Union. Reforms in the Communist world had started earlier further east: first in China in the late 1970s and in Vietnam in the mid 1980s. The changes affected society in a multitude of ways. They affected the way the political and economic system operated but also the social organization of society, the psychology of the people living in the countries, and the culture of day-to-day life.   In this essay I focus on how these changes affected the rural economy and the agricultural and food sector. I will discuss developments and performances of the countries during transition, the causes behind them, and...

Agricultural water markets: exploring limits and opportunities in Italy and Spain
Provedor de dados: 31
Autores: Pujol,   Joan; Raggi,   Meri; Viaggi,   Davide.
Agriculture is the main water-using sector in Southern European Countries, such as Spain and Italy. Innovative institutional solutions for reducing water use or increasing its efficiency are pursued by recent legislation concerning water, in particular by the Water Framework Directive (WFD). Even if not explicitly considered by the directive, water markets may be seen as a kind of instrument responding to the guiding principles of the upcoming water regulation.  The issue of water markets is very much debated in the water economics literature and particularly in the agricultural water literature. Water markets refer to a mechanism of water allocation based on the exchange of rights on water use. Water markets are proposed and supported by economic theory...

L’île de la Martinique vit aujourd’hui principalement du tourisme, de la banane et un peu de la canne à sucre (pour le rhum). L’agriculture,qui occupe plus de 14 % de la population active (4 % en France métropolitaine), perd de son poids économique, l’industrie se développe faiblement, seule la part de l’emploi dans l’administration progresse. Les ressources de l’île dépendent en partie des transferts publics et des aides européennes. Malgré une précarité et un chômage élevés, dans les vingt dernières années ces transferts ont permis un accroissement sensible du niveau de vie, qui dépasse aujourd'hui largement celui des pays voisins et concurrents de la Caraïbe. Aussi, la production agricole de masse de la Martinique ne pourrait-elle être compétitive sans...

Autores: Bojnec,   Stefan.
This paper draws attention to the specific post-civil-war situation in agriculture and the food sector in Bosnia and Herzegovina (B&amp;H). These developments are presented in an association with the overall situation in the country. Due to economic and non-economic reasons, B&amp;H faces a general problem of a lack of international competitiveness. In a current situation, there are rare products to be internationally competitive and the country relies on imports of food and other products. During the post-civil-war emergency and reconstruction stage, the bulk of food and agricultural inputs, were donated or granted by different governments, humanitarian organizations, and donors to mitigate the effects of widespread poverty caused by the war destructions...

In this study we evaluate the effect of annual productivity growth in agriculture over the 1991-2001 period on poverty in eleven developing countries. We compare this with the optimal pattern of productivity growth of comparable cost with the sole goal of maximizing poverty reduction. This comparison reveals that regional agricultural development is a viable option in the fight for poverty reduction.

Agriculture's Contribution to Swiss Climate Policy: Results of an Economic Analysis
Provedor de dados: 31
Autores: Hartmann,   Michael.
Greenhouse gas emissions from Swiss agriculture have been reduced by about 8 % since 1990. Hence, Swiss agriculture has already contributed 13 % to the national Kyoto target, although it is not legally bound to reduce greenhouse gas emissions. Since the reductions are a result of changes of agricultural policy and relative prices, related income losses can not be attributed to climate policy. In other words, the agricultural sector did not have to bear effective emission abatement costs.  If the current agricultural policy is continued, further reductions of agricultural GHG emissions by 3 to 10 % can be expected until 2010. These expectations are based on economic calculations made with the integrated agricultural allocation model S_INTAGRAL. Accordingly,...

Autores: Eggers,   Jorg; Laschewski,   Lutz; Schleyer,   Christian.
With regard to agri-environmental schemes (AES) under Regulation (EC) 1257/99, we suggest that their ineffectiveness, inefficiency, and divers uptake is inherent to the way they are institutionalised in the European CAP framework. Based on experiences of the GRANO research project that initiated two Agri-Environmental Forums in Brandenburg (Germany) to integrate local actors directly into designing and implementing local AES we argue that the process of designing AES can be conceptualised as a complex negotiation process at Laender level. The related institutional settings shape possible outcomes and scheme designs. With only "passive support" for decentralised and participatory approaches yet compulsory complex bureaucratic procedures on part of the EU,...

Agroholdings in Russia: Breaking the Vicious Circle?
Provedor de dados: 31
Autores: Hockmann,   Heinrich; Wandel,   Jurgen; Nedoborovskyy,   Andriy.
The paper discusses the accelerated emergence of agroholdings in the Russian Federation.  It is argued that the foundation of these highly integrated structures I due to the special (macro-) economic and institutional condition of the transition process in Russia. Moreover, it is shown that agricultural enterprises which are part of an agroholding were lacking behind other organisational forms in terms of economic efficiency. One reason for this finding is the highly centralized decision structures which, as experiences in Western Europe shows, are only suitable for very special agricultural value chains, but not for agriculture in general.

Twenty six breeding lines, selected from individual plant progenies of hybrids among varieties Amarilla de Marangani, Blanca de Junín, Chewecca, Faro 4, Improved Baer, Kancolla, Real, and Salares-Roja, had their agronomic characters evaluated, in Planaltina, DF, Brazil (15º36'S and 47º12'W), 1,000 masl, in randomized complete blocks, on a Ferralsol, previously limed and fertilized. Grain yield was positively associated with plant height, inflorescence length and diameter, and plant cycle. Genetic gain can be attained by selection based in these characters for commercial production of quinoa in tropical regions.

The general ecological mechanisms that determine the interactions between availability of re-sources (nutrients, water) and synthesis of defence related secondary metabolites in the plants will be presented. In short, under normal conditions in nature, where growth is limited by a relatively constant availability of nitrogen at a moderate level, plants strike a balance between defence and growth. They use a fraction of resources such as carbohydrate, N and S to reach a genetically determined normal level of defence mechanisms, which will prevent or quickly overcome most types of infections. If the local availability of nitrogen happens to increase (e.g. from decomposition of animal faeces), the growth rate increases, and the balance shifts. The...

Aire marine protégée, gestion halieutique, diversification et développement local: le cas de la reserve de biosphère du Delta du Saloum (Sénégal)
Provedor de dados: 20
Autores: Sarr, O.
Cette thèse étudie le problème de la gestion des pêches au sein d’une AMP, en tenant compte du système économique global ainsi que des transformations structurelles qui affectent celui ci, et en diversifiant les critères de gestion. Le cas d’étude est la RBDS (Sénégal). Une enquête de terrain montre que la population de cette localité diversifie ses activités essentiellement entre l’agriculture, la pêche et le tourisme. Une analyse économétrique indique que la démographie, la sécheresse et la baisse du prix de l’arachide sur le marché mondial sont les principales causes de la crise agricole dans la région. Cette crise favorise la diversification vers la pêche. Un modèle théorique étudiant ce processus montre qu’il conduit la pêche à l’équilibre de libre...

Autores: Recondo,Eduardo Francisco; Calabrese,Graciela Cristina; Alberto,María Fabiana; Lazzari,María; del Valle Fernández de Recondo,Marta Elena.
El descubrimiento del cofactor II de la heparina (HCoII), desplazó el enfoque de las investigaciones sobre el mecanismo de la coagulación desde la heparina, que se encuentra fundamentalmente en los mastocitos, hacia el dermatán sulfato (DS) que posee una distribución mucho más amplia en los tejidos y en las paredes de los vasos sanguíneos. El nuevo cofactor de la heparina es el único cuya actividad anticoagulante es estimulada por el DS, en concentraciones diez veces menores que la heparina y el heparán sulfato (HS). Se ha descripto el aislamiento de fracciones de la heparina con muy alta actividad anticoagulante a través de la interacción con la Concanavalina A y con la primera proteína del sistema del complemento (C1). En ambos casos fueron...

Ajuste osmótico em milho cultivado em diferentes sistemas de manejo de solo e disponibilidade hídrica
Provedor de dados: 86
Autores: Bianchi,Cleusa Adriane Menegassi; Bergonci,João Ito; Bergamaschi,Homero; Dalmago,Genei Antonio.
A cultura do milho é sensível ao déficit hídrico, e esta é uma causa freqüente de redução na produção de grãos. O objetivo deste trabalho foi verificar a ocorrência de ajuste osmótico em milho, cultivado em dois sistemas de manejo do solo, com diferentes disponibilidades hídricas. Os tratamentos consistiram do cultivo do milho em semeadura direta (SD) e convencional (SC), com irrigação de forma a manter a umidade do solo próxima à capacidade de campo, e sem irrigação. O ajuste osmótico foi obtido pela diferença do potencial osmótico hidratado entre as plantas irrigadas e sem irrigação. Os maiores valores de potencial mínimo de água na folha ocorreram em plantas cultivadas sob SD, em razão do maior potencial matricial da água no solo nesse sistema. O...

Aktiv jordforbedrer med krås
Provedor de dados: 21
Autores: Pommeresche, Reidun.
En god bestand meitemark spiser seg gjennom 25 % av matjordlaget hvert år. De har krås, og mikroorganismer i tarmen. Dermed går omdanningen av organisk materiale mye raskere med meitemark i jorda enn uten. Meitemarken bygger opp humus (mold), og ekskrementene er langt mer næringsrike og tilgjengelige for planterøtter enn jorda rundt.

Foi estudada a alimentação natural do peixe-rei (Odontesthes bonariensis Cuvier &amp;amp; Valenciennes, 1835) nas lagoas Mirim e Mangueira, Estado do Rio Grande do Sul, Brasil. O conteúdo estomacal de 60 indivíduos de peixe-rei (Odontesthes bonariensis) provenientes dessas lagoas mostraram que esta espécie tem amplo espectro alimentar. Uma grande variedade de alimentos é consumida, sem afetar o crescimento, pois os peixes dos dois ambientes apresentaram condição corporal semelhante. Na lagoa Mangueira, crustáceos (Isopoda) representaram 65% da dieta dos peixes e na lagoa Mirim, moluscos (Bivalvia e Gastropoda) perfizeram 70% dos conteúdos de estômago identificados.

Autores: Vergani, M.
The yellowtail kingfish, Seriola lalandi, Carangidae (Valenciennes, in Cuvier y Valenciennes, 1833) is a pelagic, schooling fish, with gregarious behaviour. It is a circumglobal species from tropical and temperate waters. Adult S. lalandi migrate to Argentine waters (SW Atlantic) during summer months (January-April). They have been reported from Argentine waters in depths of 20-36 m between 36°S and 38° and, as reported elsewhere in the world, are often associated with rocky reefs. Samples of S. lalandi were caught using trolling lines during daytime around rocky reefs at 35° 52'-35° 58'S and 54° 45'-54° 48'W, on February 15-22, 2002. Sixty-six adult S. lalandi were analyzed, with specimens measured (LT) and weighted (WT). The length-weight relationship...

Widespread concern over transmission capacity requires theoretical support to infer inadequacy from observed trends indicating reductions in the ratio of transmission to generation capacity over time. If integrated utilities had been regulated with allowed returns exceeding capital costs, transmission generation ratios would have been excessive, and observed trends might be a correction. However, numerous commentators claim that post-restructuring transmission rates have been too low, with NIMBY also discouraging investment. We model the possibility that inadequate separation between generation and transmission may result in reduced investment, in order to preserve incumbent market power in generation. However, consideration of transmission price caps and...

Allergy between the ears?
Provedor de dados: 26
Autores: Shepherd, R.
Estimates of the true prevalence of food allergies tend to be around 2-3% in adults, whereas the perceptions of food allergies by the public tend to be much higher. There are many potential reasons for these differences, including the tendency by the public to include all forms of intolerances and adverse food reactions rather than just true allergies. But even taking this into account, the prevalence of food intolerances is higher than that measured in controlled studies. While there has been relatively little work on how the public thinks about allergies, there has been more extensive work on perceptions of other risks. Here one of the reasons for differences between lay and expert estimates of risk lies in the public considering many other...

Allergy prevention: consumer perspectives
Provedor de dados: 26
Autores: Reading, D.
Consumer concerns about allergy have increased considerably in the last decade. Peanut allergy in particular has generated panic among many families, and there is often a misconception that children affected are unlikely to reach adulthood. Patientsupport organizations offer essential advice and guidance to these people, with a great deal of effort directed towards allergen avoidance. The Anaphylaxis Campaign receives approximately 20,000 enquiries annually - the vast majority being people seeking information about food allergy - and every year sends out 140,000 information sheets. Its website (www.anaphylaxis.org.uk) attracts 4,000 visits per day. Allergen avoidance is difficult enough for the person with access to high-quality information, but much...

Allocation of CO2 Emissions Allowances in the Regional Greenhouse Gas Cap-and-Trade Program
Provedor de dados: 31
Autores: Burtraw,   Dallas; Palmer,   Karen L.; Kahn,   Danny.
Cap-and-trade programs for air emissions have become the widely accepted, preferred approach to cost-effective pollution reduction. One of the important design questions in a trading program is how to initially distribute the emissions allowances. Under the Acid Rain program created by Title IV of the Clean Air Act, most emissions allowances were distributed to current emitters on the basis of a historic measure of electricity generation in an approach known as grandfathering. Recent proposals have suggested two alternative approaches: allocation according to a formula that is updated over time according to some performance metric in a recent year (the share of electricity generation or something else) and auctioning allowances to the highest bidders....

Allocation of Land at the Rural-Urban Fringe Using a Spatially-Realistic Ecosystem Constraint
Provedor de dados: 31
Autores: Bauer,   Dana Marie; Swallow,   Stephen K.
Development in rural-urban fringe communities is increasing with the potential to damage healthy ecosystems and endanger the long-term persistence of resident flora and fauna.  The environmental impacts of development include loss, degradation, and fragmentation of wildlife habitat, increased air and water pollution, increased soil erosion, and decreased aesthetic appeal of the landscape.  Current land use policies rarely incorporate features of landscape-scale ecosystem health.  This paper develops a model that combines ecological and economic constructs to determine the optimal allocation of development across a spatially-realistic landscape.  The land allocation model establishes links between long-term metapopulation persistence and development through...

Allocative and Technical Efficiency of Corporate Farms in Russia
Provedor de dados: 31
Autores: Grazhdaninova,   Margarita; Lerman,   Zvi.
This study is aimed to analyze Russian corporate farms technical efficiency using DEA and allocative efficiency basing upon VMP calculations. The estimations are carried out on three aggregation levels: total farm, sectors (livestock and crops production) and selected commodities (grain, sunflower, beef, milk and pork), using survey data. The results of analyses suggest that there is no substantial misallocation of resources given current input and output prices. High technical efficiency scores speak for production technologies being homogeneous and mean that simple extension of "best practice" production will not eliminate the large productivity gap between Russia and the developed market economies.

Allometric scaling of biological rhythms in mammals
Provedor de dados: 48
Autores: Günther,Bruno; Morgado,Enrique.
A wide spectrum of cyclic functions in terrestrial mammals of different size, from the 3-gram shrew to the 3-ton elephant, yields an allometric exponent around 0.25, which is correlated _ as a kind of common denominator _ with the specific metabolic rate. Furthermore, the applicability of these empirical findings could be extrapolated to chronological events in the sub-cellular realm. On the other hand, the succession of growth periods (T98%) until sexual maturity is reached also follows the 1/4 power rule. By means of Verhulst's logistic equation, it has been possible to simulate three different biological conditions, which means that by modifying the numerical value of only one parameter, revertible physiological and pathological states can be obtained,...

Alterações na qualidade de raízes de mandioca(Manihot esculenta Crantz) minimamente processadas
Provedor de dados: 64
Autores: Alves,Andreia; Cansian,Rogério Luis; Stuart,Giane; Valduga,Eunice.
A conservação pós-colheita das raízes de mandioca tem sido uma preocupação das indústrias e produtores, devido ao curto tempo de estocagem e a alta perecibilidade das raízes. Dois fenômenos são apontados como responsáveis pela deterioração das raízes, um de ordem fisiológica, provocando a perda inicial da qualidade por meio do desenvolvimento da descoloração vascular do tecido parenquimatoso, e o outro, de ordem microbiana, que se segue à fisiologia, responsável pela decomposição do produto. Dessa forma, com o presente trabalho, objetivou-se estudar a conservação das raízes de mandioca (Manihot esculenta Crantz), submetidas à higienização em água clorada e armazenadas em três tipos de embalagens, bandeja de isopor envolta em filme de policloreto de vinila...

ALTERATION OF NITROGEN CYCLING BY AGRICULTURAL ACTIVITIES, AND ITS ENVIRONMENTAL AND HEALTH CONSEQUENCES
Provedor de dados: 73
Autores: Cleemput,Oswald van; Boeckx,Pascal.
The food demands of the increasing world population puts pressure on land use and N availability. In this paper an overview is given of the different N cycling processes affected by agricultural activities. Of the amount of N added to the soil, about half is removed from the field as harvested crop, while the remainder of the N is incorporated into soil organic matter or is lost to other parts of the environment. During the last decades there has been much research on environmental consequences of agricultural activities, mainly on emission of gaseous N compounds (NH3, NO, N2O and N2), but also on N leaching, runoff and erosion. Study of the factors controlling loss of N is complex because of their multiplicity and mutual interactions. More recently...

Altered dopamine levels induced by the parasite Profilicollis antarcticus on its intermediate host, the crab Hemigrapsus crenulatus
Provedor de dados: 48
Autores: ROJAS,JOSÉ MIGUEL; OJEDA,F. PATRICIO.
A serotonergic pathway is apparently involved in parasite-host interactions. Previous studies conducted in our laboratory showed increased rates in oxygen consumption and alterations in body posture in the crab Hemigrapsus crenulatus parasitized by the acanthocephalan, Profilicollis antarcticus. Such changes may be related to the functions described for biogenic amines in crustaceans. During the infective stage the acanthocephalans live freely in the hemocelomic cavity, suggesting that the possible alteration induced by biogenic amines may be related to their neurohormonal function in crustaceans. To test whether the presence of P. antarcticus produced neurohormonal changes in its intermediate host, H. crenulatus, we analyzed serotonin and dopamine levels...

Alternagin-C, a disintegrin-like protein from the venom of Bothrops alternatus, modulates alpha2ß1 integrin-mediated cell adhesion, migration and proliferation
Provedor de dados: 56
Autores: Selistre-de-Araujo,H.S.; Cominetti,M.R.; Terruggi,C.H.B.; Mariano-Oliveira,A.; De Freitas,M.S.; Crepin,M.; Figueiredo,C.C.; Morandi,V.
The alpha2ß1 integrin is a major collagen receptor that plays an essential role in the adhesion of normal and tumor cells to the extracellular matrix. Alternagin-C (ALT-C), a disintegrin-like protein purified from the venom of the Brazilian snake Bothrops alternatus, competitively interacts with the alpha2ß1 integrin, thereby inhibiting collagen binding. When immobilized in plate wells, ALT-C supports the adhesion of fibroblasts as well as of human vein endothelial cells (HUVEC) and does not detach cells previously bound to collagen I. ALT-C is a strong inducer of HUVEC proliferation in vitro. Gene expression analysis was done using an Affimetrix HU-95A probe array with probe sets of ~10,000 human genes. In human fibroblasts growing on collagen-coated...

Alternative Approaches for Promoting Fertilizer Use in Africa, with Particular Reference to the Role of Fertilizer Subsidies
Provedor de dados: 31
Autores: Crawford,   Eric W.; Jayne,   Thomas S.; Kelly,   Valerie A.
This paper outlines the role of improved soil fertility in the process of structural transformation, and examines specific financial, economic, social, and political arguments in favor of promoting increased fertilizer use, particularly in smallholder farming systems. This paper draws experiences and insights from the literature on which policies and programs appear to work best and which least well in providing a consistent and growing supply of fertilizer to smallholders. Particular attention is given to addressing the question of fertilizer subsidies: Under what circumstances are they warranted and what form should they take, if and when they are implemented?

Autores: Aina,   O.M.; Adetogun,   A.C.; Adedokun,   M.O.; Onilude,   M.A.
In a conversion efficiency study, 10 sawmills were selected out of the existing 44 in Abeokuta metropolis. For 5 days per week in each of the 10 sampled sawmills, the volumes of all the round logs to be converted each day were determined using Newton’s formula. At the end of the days work, the volumes of all lumbers converted were determined and were subtracted from those obtained in the morning, whatever is obtained was the volumes of wood wastes generated in each of the sampled sawmills. This study revealed that the mean conversion efficiency of the 10 selected mills was 56.05%. As a result, the total volume of wood waste generated per day by the 10 mills was approximately 52.00m3. In the entire Abeokuta metropolis 2288m3 of wood wastes will be generated...

Alternative Co-operative Structures for the Agri-food Sector: An Exploratory Study
Provedor de dados: 31
Autores: Doyon,   Maurice.
In a context of internationalisation and concentration, bio-foods co-operatives often face problems of capital access and governance. According to Spear (2001), limited access to capital, management structure, governance conflicts, and the local, regional or national focus of co-operatives limit their expansion. Recent events in Canada, such as Agricore going public and Dairyworld being absorbed by a corporation, have reinforced this perception (Thibault and Dupuis, 2003). In this evolving competitive environment, the traditional co-operative model cannot thrive and succeed if static. New hybrid co-operative models are emerging, and an analysis of these models should contribute to an understanding of the trade-off between co-operative values and other...

Alternative Market Access Scenarios in the Agricultural Trade Negotiations of the Doha Round
Provedor de dados: 31
Autores: Antimiani,   Alessandro; Conforti,   Piero; Salvatici,   Luca.
The paper explores an important issue in multilateral agricultural trade negotiations, namely the approach taken to reduce tariffs, simulating possible liberalization scenarios.  The analysis is based on the model of the Global Trade Analysis Project (GTAP), and on the related version 6.0 database.  Scenarios are run on a 2013 baseline, built by taking into account a number of events that have affected (and will further affect) world agricultural markets up to that period, focusing on the effects that are specifically attributable to further trade liberalization in the Doha Round.  The policy strategies analyzed are two hypothetical liberalization scenarios in terms of market access and export competition, plus a free agricultural trade benchmark scenario....

Alternative Market Access Scenarios in the Agriculture Trade Negotiations of the Doha Round

Autores: Antimiani,   Alessandro; Conforti,   Piero; Salvatici,   Luca.
The article explores possible outcomes of the Doha Development Agenda by simulating agricultural liberalization scenarios with a modified version of the Global Trade Analysis Project (GTAP) model and the related version 6.0 database. A 2013 baseline is employed to analyze two hypotheses in the areas of market access and export competition. Proportional cuts in tariffs are compared with a Swiss-formula approach. Welfare gains arise both in developed and developing countries, and, at least in principle, both groups should support deep reforms. Results suggest that the choice of the nature of the formula is not crucial in determining an effective increase in market access.

Autores: Lima,Herdjania Veras de; Silva,Álvaro Pires da; Imhoff,Sílvia; Neves Junior,Afrânio Ferreira.
Due to the narrow window of ideal moisture conditions required for collecting undisturbed soil samples from hardsetting horizons in the field, this study compared the efficiency of an alternative method of soil core removal in the laboratory with that of the traditional field method by using measurements of soil bulk density data (Db). In a first sampling, cylinders were removed with a soil sampler in the field. In a second sampling, large soil blocks were removed with Kubiena-type zinc (brass) boxes in the field. Volumetric core cylinder samples were removed from these blocks in the laboratory with a manual hydraulic pump. There were no differences between the Db values determined from the laboratory and the field coring method. The laboratory method was...

Alternative Territorial Breakdowns of Statistics for Supporting Rural Policies
Provedor de dados: 31
Autores: Lauwers,   Ludwig H.; Kerselaers,   Eva; Lenders,   Sonia; Vervaet,   Mieke; Vervloet,   Dirk.
In order to support rural policy making with appropriate information, alternative territorial breakdowns of statistics are necessary. This paper shows how the widely used criterion of 150 inhabitants per km² can be fine tuned to better account for local specific conditions, in particular high population densities. Alternative population density thresholds are confronted with local perceptions of rurality, aggregated in a rurality index. The method is illustrated for two regions that differ in urbanisation level. The rurality index not only increases the discriminatory power, but also helps to find a less erroneous and more robust proxy for international comparable breakdowns of statistics.

Selective breeding of shrimp for viral resistance is established for species like L. vannamei and L. stylirostris. However, selection for bacterial infection resistance is not documented. In New Caledonia, "Syndrome 93" is a vibriosis that affects cultured shrimps during the cool season with survival from 15 to 30%. Current practises for breeders rearing at low densities do not improve the resistance of the offsprings mainly because selection pressures for "Syndrome 93" are low. Even after the fifth generation, survival improvement is not significant.

Visceral leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus. Dog is the major source of infection to man, especially in urban areas. The authors report a case of visceral leishmaniasis in a pit bull female dog from Bocaina, São Paulo, Brazil. The animal presented clinical signs compatible with leishmaniasis, including skin lesions in the body and partial damage of the external ears. The indirect fluorescent antibody test (IFAT) demonstrated a titer of 1280, and promastigote forms of Leishmania sp were isolated by the culture of bone marrow puncture. Cytological analysis of the lymph node and smear of the bone marrow puncture revealed macrophages containing amastigote forms of Leishmania sp in their inner region. The test of...

Amido resistente: características físico-químicas, propriedades fisiológicas e metodologias de quantificação
Provedor de dados: 65
Autores: Walter,Melissa; Silva,Leila Picolli da; Emanuelli,Tatiana.
Encontrado em diversos alimentos, o amido é a mais importante fonte de carboidratos da dieta. Potencialmente digerível pelas enzimas no trato gastrintestinal, é absorvido na forma de glicose no intestino delgado. Apesar disso, quantidade significativa de amido pode escapar a esta digestão, alcançando o cólon, onde é fermentado pela flora bacteriana. Esta fração, conhecida como amido resistente, tem sido intensamente estudada nos últimos anos devido aos potenciais benefícios à saúde humana. Vários métodos são utilizados para a determinação do amido resistente. Porém, nenhum é de aceitação unânime, uma vez que apresentam diferenças importantes nos protocolos e nos resultados obtidos. Neste contexto, o presente trabalho visa fornecer subsídios para um melhor...

Amino acid and soil organic matter content of topsoil in a long term trial with farmyard manure and mineral fertilizers
Provedor de dados: 21
Autores: Scheller, Edwin; Raupp, Joachim.
Commencing in 1980, a long-term experiment is carried out to compare mineral fertilizers (MIN), composted manure (CM) and composted manure with application of biodynamic preparations (CMBD) at three different fertilizer application rates. With mineral fertilizer the lowest contents of 0.80% C and 0.069% N, with manure 0.90% C and 0.080% N, and with manure and biodynamic preparations 1.08% C and 0.094% N were achieved in the topsoil. 42.9 to 53.7% of Nt was bound in 18 protein amino acids including asparagine and glutamine. Amino acid contents in the hydrolysates of the topsoil were significantly different according to fertilizer type: MIN &lt; CM &lt; CMBD. The higher contents in manure fertilized plots were observed even at the lowest rate of fertilizer...

AMMONIA ABATEMENT STRATEGIES IN LIVESTOCK PRODUCTION: A CASE STUDY OF A POULTRY INSTALLATION
Provedor de dados: 31
Autores: Angus,   Andrew J.; Hodge,   Ian D.; Sutton,   M.A.
This study uses a linear programming approach to compare the potential effectiveness of uniform rules (under the Integrated Pollution Prevention and Control Directive) and a landscape-scale based policy for reducing ammonia (NH3) emissions and their related impacts from a case study poultry installation.  The model incorporates a variety of potential NH3 abatement techniques. It also incorporates the first application of a spatial model of the diffusion of environmental impacts from NH3 emissions. This models N deposition at a nearby nature reserve. The model finds that the uniform rules proposed under the Integrated Pollution Prevention and Control Directive are likely to be ineffective in certain contexts and that a landscape-scale approach is more...

Amount and Spatial Distribution of Public Open Space to Maximize the Net Benefits from Urban Recreation
Provedor de dados: 31
Autores: Kovacs,   Kent F.
The spatial arrangement of public open spaces in communities has an important influence on the recreational net benefits from those public open spaces.  A prime example of a public open space in communities where spatial arrangement is important is parks.  From the perspective of maximizing the net benefits of recreation, there is a tradeoff between placing all the land for parks in a single park and making several parks to reduce the travel costs of households to the parks.  If several parks are made, then the amount of land in each park is reduced, and the recreational net benefit of a trip to any of the parks is less.  Since recreation is an important source of value from parks, an examination of an optimal spatial arrangement of parks for recreation in...

AMP-deaminase in elasmobranch fish: A comparative histochemical and enzymatic study
Provedor de dados: 5
Autores: Thebault, Marie-t; Izem, Lahoucine; Leroy, Jean Paul; Gobin, Eric; Charrier, Gregory; Raffin, Jean-paul.
AMP-deaminase activity was measured in white muscle from a wide range of fish, including one cyclostome, 13 chondrosteans, and one teleost to elucidate the pattern of the AMP-deaminase activity in white muscle of fish. Compared to a mammalian (rat) muscle extract, low enzyme activities are found in the cyclostome and two elasmobranchs from two families (Scyliorhinidae, Hexanchidae). In contrast, higher AMP-deaminase activities, similar to mammals, are expressed in Squalidae, all families of skates, Chimaeridae and in the teleostean fish. We then compared AMP-deaminase activities in red and white muscles from two representative elasmobranch fish, the dogfish (Scyliorhinus canicula) and the thornback ray (Raja clavata). The fibre type composition and...

Amphibians of an open cerrado fragment in southeastern Brazil
Provedor de dados: 49
Autores: Brasileiro,Cínthia Aguirre; Sawaya,Ricardo J.; Kiefer,Mara C.; Martins,Marcio.
The Cerrado encompasses ca. 2 million km² in Brazil. Most Cerrado areas have been greatly disturbed in the past decades. Only 20% of this biome remain undisturbed, and only 1.2% is protected. Knowledge on the biology and diversity of Cerrado amphibian assemblages is still incipient. Here we present natural history information (habitat use and reproductive activity) of 28 species of frogs from the Estação Ecológica de Itirapina (EEI), and compare the composition of this assemblage with those of other Cerrado areas, other open areas, and a few forest areas throughout Brazil. We demonstrate that the Itirapina assemblage is more similar to those of other open areas than to those of forests, even when the latter are geographically closer. Six species occurred...

Amylase polymorphism affects growth in the cupped oyster Crassostrea gigas
Provedor de dados: 5
Autores: Huvet, Arnaud; Samain, Jean-francois; Boudry, Pierre; Bedier, Edouard; Ropert, Michel; Van Wormhoudt, A.
The better understanding of physiological and environmental factors that determine optimal food conversion efficiencies is of major interest for the cupped oyster Crassostrea gigas for which the strong increase of aquaculture has been correlated in France with a decrease in productivity due to competition between aquatic species for limited food supplies at grow-out sites. To investigate the non-neutrality of the polymorphism of amylase, a key enzyme for carbohydrate assimilation, in oyster physiology, we report in the present paper the growth and survival measurement of amylase genotypes within five bi-parental C. gigas families, bred to be polymorph at the two PCR-RFLP amylase markers, and reared over one year under standard culture conditions in two...

We examined the effects of Amylomyces rouxii, which is a mold found in some fermented foods in Indonesia, on serum cholesterol and hepatic LDL receptor mRNA in rats. Rats were fed a 0.5% cholesterol-enriched diet with (A. rouxii group) or without (control group) 30g/kg A. rouxii for 4 wk. There were no significant differences in the body weight, food intake or liver weight among the groups. However, the weight of the cecum in the A. rouxii-fed group was significantly higher than that in the control group. The cecal pH in the A. rouxii-fed group was significantly lower than that in the control group. Cecal acetic acid, propionic acid and total SCFA concentrations in the A. rouxii-fed group were significantly higher than those in the control group. The serum...

An acid-sensing ion channel that detects ischemic pain
Provedor de dados: 56
Autores: Naves,L.A.; McCleskey,E.W.
Ischemic pain occurs when there is insufficient blood flow for the metabolic needs of an organ. The pain of a heart attack is the prototypical example. Multiple compounds released from ischemic muscle likely contribute to this pain by acting on sensory neurons that innervate muscle. One such compound is lactic acid. Here, we show that ASIC3 (acid-sensing ion channel #3) has the appropriate expression pattern and physical properties to be the detector of this lactic acid. In rats, it is expressed only in sensory neurons and then only on a minority (~40%) of these. Nevertheless, it is expressed at extremely high levels on virtually all dorsal root ganglion sensory neurons that innervate the heart. It is extraordinarily sensitive to protons (Hill slope 4,...

An additional record of Oichnus excavatus Donovan &amp; Jagt from the Maastrichtian (Upper Cretaceous) of southern Limburg, The Netherlands
Provedor de dados: 16
Autores: Donovan, S.K.; Jagt, J.W.M.
A single example of Oichnus excavatus Donovan &amp; Jagt, infesting the holasteroid echinoid Hemipneustes striatoradiatus (Leske), is reported from the upper Meerssen Member, Maastricht Formation (uppermost Maastrichtian), of the former Blom quarry, Berg en Terblijt, southern Limburg, The Netherlands. This is the first evidence that O. excavatus may be more widely distributed in the type area of the Maastrichtian than previously assumed. The embedment structure occurs just below the ambitus and close to the peristome, suggesting that the producing organism may have been ingesting detritus from the sea floor rather than filter feeding, the more usual interpretation of its behaviour.

An American BSE Crisis: Has it affected the Value of Traceability and Country-of-Origin Certifications for US and Canadian Beef?
Provedor de dados: 31
Autores: Ward,   Ruby A.; Bailey,   DeeVon; Jensen,   Robert T.
With a BSE incident in the United States (US) in December of 2003, questions arose about the effect of the incident on consumers in the US. The purpose of this paper is to determine if traceability systems for beef can help preserve consumer demand following the discovery of BSE. Auctions were conducted approximately 3 weeks before and after the December 2003 BSE incident in the U.S It was found that overall there was no effect on the size of the bribes needed by the BSE incidence. However, for some groups there were important changes. The results indicate that information about traceability and country of origin is valuable to consumers. They also suggest that greater uncertainty about certifications and assurances for beef existed among the participants...

As a consequence of global changes to trade policy, there are likely to be significant impacts on international agricultural trade. Clearly producers in the European Union (EU) will experience considerable changes to the structure of their industry, and for a country such as New Zealand, heavily dependent on agricultural exports, changes to policy and markets have the potential to significantly affect the economy. The potential competition from China in terms of agricultural commodities as well as its potential as an export destination for NZ are also important considerations.

In this paper we examine some of the economic forces that underlie economic growth at the county level. In an effort to describe a much more comprehensive regional economic growth model, we address a variety of different growth hypotheses by introducing a large number of growth related variables. When formulating our hypotheses and specifying our growth model we make liberal use of GIS (geographical information systems) mapping software to "paint" a picture of where growth spots exist. Our empirical estimation indicates that amenities, state and local tax burdens, population, amount of primary agriculture activity, and demographics have important impacts on economic growth.

Autores: Onianwa,   Okwudili O.; Wheelock,   Gerald; Mojica,   Maribel N.
This study examines factors affecting users of farmer-to-consumer direct markets. Data for the study were generated by telephone survey administered to 400 random sample consumers in Alabama. The sample was stratified to ensure adequate representation of both metro and non-metropolitan areas. A binary logit model was employed to analyze the data. Results revealed that education was the most significant variable with regard to shopping at farmer-to-consumer direct markets. Although income by itself was not significant, families with children were more likely to shop at a farmer-to-consumer direct market as their income increases.

Autores: Lozano,   Javier; Gomez Gomez,   Carlos Mario; Rey-Maquieira,   Javier.
In this paper we try to build a bridge between the traditional analysis of the evolution of tourism destinations and economic growth theory. With such an aim we develop an environmental growth model for an economy specialized in tourism and we derive the pattern of tourism development with numerical calculations. The results of our simulations do not contradict the general pattern of evolution implied in the Tourism Area Life Cycle Hypothesis, being environmental deterioration and public goods congestion the main reasons for the stagnation of the tourism destination. We also show the importance of the quality of private tourism services in the evolution of the tourism destination.

Autores: Cravero,Vanina Pamela; Picardi,Liliana Amelia; Cointry,Enrique Luis.
The inheritance of head color and tightness in globe artichoke was studied utilizing crosses between inbreed lines and between clones and self-pollinated clones from different genetic origins. These genetic materials were sowed in a completely randomized design with 20 plants per plot and genotype. Globe artichoke heads were classified into three colors (purple-green, purple and green) and three head tightness types (compact, fairly compact and soft) and the segregating ratios for these traits tested in each offspring using the chi-square test. Crosses between green and purple inbreed lines produced only purple-green heads but F2 generation segregated at a purple-green:purple:green ratio of 9:3:4. The self-pollinated compact head clones produced a compact...

An appropriate level of risk: Balancing the need for safe livestock products with fair market access for the poor
Provedor de dados: 31
Autores: Stevens,   Christopher; Sones,   Keith; Nin Pratt,   Alejandro; Perry,   Brian D.
This paper examines the role of livestock products as commodities of trade, responding to the demand and higher prices that many external markets offer, and at the same time providing important contributions to the development process in poorer countries.  It highlights that this opportunity is not without its threats: much of the Western world has, over the last half century in particular, invested substantial amounts of money in controlling and eradicating many infectious diseases of livestock, and in building up healthy and highly productive animals, the products derived from which earn them very large sums of money on world markets.  Such countries are not willing to take risks that could threaten their livestock industries, and their domestic and...

An assessment of five different theoretical frameworks to study the uptake of innovations
Provedor de dados: 31
Autores: Botha,   Neels; Atkins,   Kris.
There are several theoretical frameworks one can draw upon to study the adoption process. Extension Theory, Bounded Rationality, Diffusion Theory, the Theory of Reasoned Action and Consumer Behaviour Theory were of particular interest to us. In assessing the frameworks we looked for contradictions, and how and whether these frameworks could be used to study the adoption process. The assessment was done by using our own conceptual framework of the adoption process and we discuss the results in this paper. We found that the different frameworks don‘t contradict each other and when combined into our conceptual framework they offer very useful constructs for studying the adoption process.

An Assessment of Future Markets for Crops Grown Along the Columbia River: Economic Implications of Increases in Production Resulting from New Agricultural Water Rights Under the Columbia River Initiative
Provedor de dados: 31
Autores: Capps,   Oral, Jr.; Williams,   Gary W.
This report examines the likely effects of additional agricultural water rights under the Columbia River Initiative (CRI) on net crop revenues (hay, orchards, vegetables, potatoes, wheat, and other crops) in the state of Washington over the next 20 years. This study corrects for four potentially serious methodological flaws made in two previous studies associated with the CRI and concludes that those studies substantially overestimated the net revenues accruing to producers in the Columbia River area from new irrigated acreage under the CRI. In fact, the net revenues are more likely to be negative than positive. Methodological errors made in the two previous studies lead to results that support a policy prescription that is just the opposite of what would...

An Assessment of the Economic, Environmental and Social Impacts of the Ricecheck Program
Provedor de dados: 31
Autores: Singh,   Rajinder Pal; Brennan,   John P.; Lacy,   John; Steel,   Felicity.
Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.

Autores: Ulmer,   Ann; Holcomb,   Rodney B.; Woods,   Michael D.; Willoughby,   Charles V.; Tilley,   Daniel S.
The evolution of value-added centers at land-grant universities, along with the recent development of numerous Ag Innovation Centers, has been viewed as a sign of a shifting emphasis to value-added agriculture research and technical assistance efforts. The entities that fund these centers, be they state or federal government, have a vested interest in the economic impacts of these centers. However, evaluating the efforts of a public good is not always an easy task. An economic-impact study of the Oklahoma Food and Agricultural Products Center (FAPC) was conducted to assess the total economic impacts of the firms assisted by the FAPC on Oklahoma's economy. A telephone survey was used to collect the necessary data and IMPLAN was used to estimate direct,...

An Assessment of the Potential Consumption Impacts of WHO Dietary Norms in OECD Countries
Provedor de dados: 31
Autores: Srinivasan,   Chittur S.; Shankar,   Bhavani; Irz,   Xavier T.
The member countries of the World Health Organization (WHO) have recently endorsed its Global Strategy on Diet, Physical Activity and Health. The strategy emphasizes the need to limit the consumption of saturated fats and trans fatty acids, salt and sugars, and to increase consumption of fruits and vegetables in order to combat the growing burden of non communicable diseases. Adherence to the norms recommended by the WHO would call for major changes in the consumption, production and trade of several key food products and several sectors of the food industry have expectedly raised serious concerns about the potential impact of these norms on their future growth prospects. This paper attempts a broad quantitative assessment of the consumption impacts of...

An early seal (Mammalia, Pinnipedia) from the Middle Miocene (Langhian) of Miste (The Netherlands)
Provedor de dados: 16
Autores: Schneider, S.; Heissig, K.
A single, upper premolar tooth of a seal from the Miste mollusc bed (Miocene, middle Langhian: The Netherlands) is determined as an upper P3 of Miophoca cf. vetusta Zapfe. Fossils of this species and genus have to date only been reported from the Late Badenian (uppermost Langhian) of the Central Paratethys, at “Neudorf-Sandberg” (Devínská Nová Ves, Slovakia). This latter locality, however, is some two million years younger than the Miste Bed. The tooth from Miste represents the first evidence for the presence of the genus Miophoca in the North Sea Basin.

An Econometric Analysis of Price Dynamics in the Presence of a Price Floor:  The Case of American Cheese
Provedor de dados: 31
Autores: Chavas,   Jean-Paul; Kim,   Kwansoo.
In this paper, we present an econometric analysis for the effects of a price floor on price dynamics and price volatility. A price floor (implemented as a part of government pricing policy) provides a censoring mechanism for price determination. We specify and estimate a dynamic Tobit model under time-varying volatility.  The model is applied to analyze the effects of a price support program on price dynamics and price volatility in the U.S. American cheese market.  The econometric analysis provides useful insights on price dynamics in the presence of a government-determined price floor.

An Econometric Model of CGE Simulations
Provedor de dados: 31
Autores: Hess,   Sebastian.
CGE models are widely used tools for economic assessments of trade policy changes. However, overall confidence in their results tends to be low. We employ the methodological framework of meta-analysis in order to approach a quantitative comparison of CGE-based simulation results. Therefore, we compile a dataset of twelve recent Doha simulations and fit a linear regression model that explains the variance between simulation results on the regional level as a function of various modeling characteristics. The estimates are broadly in range with documented qualitative knowledge about modeling assumptions. The size of the sample limits general conclusions; however, an ongoing research project will extend the approach to a larger sample.

An Economic Analysis of Consumer Expenditures for Safe Drinking Water: Addressing Nitrogen Risk with an Averting Cost Approach
Provedor de dados: 31
Autores: Tenwalde,   Tracy; Jones,   Eugene; Hitzhusen,   Frederick J.
This article presents a procedure for estimating averting expenditures through the analyses of two data sources: (1) packaged water sales from 18 national supermarket chain stores in the Columbus, Ohio Metropolitan Area (COMA); and (2) treatment expenditures for both high and low service water from a local drinking water treatment facility owned and operated by the Columbus, Ohio municipality.  The averting behavior results from a nitrogen advisory for drinking water for 1/3 of the COMA.  The study concentrates on estimating these averting expenditures as representative of averting behavior for a market and non-market good trade-off.  This article concentrates on the economic consequences of the nitrogen pollution problem as it affects households through...

Autores: Chinnappa,   B.
The economic feasibility of land reclamation technologies adopted by the farmers of Tungbhadra Command Area in Karnatka for amelioraion of irrigation-induced soil degradation has been studied. The data have been analysed using tabular method and partial budgeting method. It has been found that the available technologies are not being spread effectively among the affected farm households. Amongst different technologies followed by the farmers, adoption of leaching has been found least costly and could result in an incremental output of 14 quintals per hectare on saline soils of both head- and mid-regions. Green manuring has been observed to be another effective technology and could enhance crop yields on saline as well as waterlogged soils. Partial...

The objective of this paper is to develop an economic analysis of the impacts of further trade liberalization on Asian dairy markets. In order to achieve this, we first make a review of Asian dairy policies from the perspective of domestic support, market access and export subsidy. Then a world dairy model is employed, which reflects both vertical and spatial characteristics of the world dairy sector. We analyze the separate and combined impacts of eliminating Japan's domestic dairy subsidy, removing other Asian countries dairy trade policies excluding Japan, eliminating all Asian countries domestic dairy and trade policies, and multilateral dairy trade liberalization around the world. We find that Japan and Korea's producers will suffer much bigger losses...

An Economic Evaluation of a Pest Management Control Program: "Outfox the Fox"
Provedor de dados: 31
Autores: Jones,   Randall E.; Saunders,   Glen; Balogh,   Suzy.
Foxes are regarded as a serious pest of environmental and grazing systems in Australia. The fox is a recognised predator of native wildlife and has been a significant contributor to the population decline of many native mammal, bird and reptile species. There are also claims that foxes may account for up to 30% of lamb mortalities in some areas, while mortality due to predation of 2 to 5% is more likely in most regions. The ‘Outfox the Fox’ program was established by NSW Agriculture in conjunction with a number of Rural Land Protection Boards to achieve a more strategic and coordinated fox baiting program. This program relies on a community driven and integrated management approach to the problem. The main features are to synchronise baiting across...

An Economic Impact Assessment of Bovine Tuberculosis in South West England
Provedor de dados: 31
Autores: Sheppard,   Andrew; Turner,   Martin M.
In England, over the last decade the rising incidence of bovine TB has resulted in recognised economic impacts on the agricultural and ancillary industries. Nowhere has the dramatic increase in bovine TB been more evident than in Southwest England, a region which is characterised by smaller, family-run farms often specialising in relatively extensive bovine livestock systems, whether dairying or beef production. The economic impacts result from the nature of the disease, the government's control measures (restrictions on movement of cattle on and off the farm, repeat testing and compulsory cleaning) and the impact of test 'failures' on the normal marketing of livestock and product.   Moreover, this worsening of the disease situation - and hence increasing...

AN ECONOMIC MODEL OF U.S. IMPORTS OF BUTTER AND MILK FAT PRODUCTS
Provedor de dados: 31
Autores: Bailey,   Kenneth W.; Wu,   Zhen.
This study developed a model to explain monthly imports of butter and butter substitutes. The U.S. imports butter and other high milk fat products that can substitute for a strict definition of butter. These products include dairy spreads, butter substitutes, anhydrous milk fat, and food preparations. The U.S. imports these high milk fat products under a tariff-rate quota system (TRQ) implemented by the World Trade Organization (WTO). This study quantified all the milk fat contained in U.S. butter and butter substitute imports. A conceptual model was developed to explain imports of these products under a TRQ system. And an econometric model was estimated to analyze the economic factors that drive over-quota imports. The model found that the wedge between...

An Emerging Agricultural Problem in High-Performing Asian Economies
Provedor de dados: 31
Autores: Hayami,   Yujiro.
Policies to tax farmers in low-income countries and policies to subsidize them in high-income countries have been identified as a major source of the disequilibrium of world agriculture. Recently, as many high-performing economies in Asia advanced from the low-income to the middle-income stage through successful industrialization, they are confronted with the problem of a widening income gap between farm and non-farm workers corresponding to rapid shifts in comparative advantage from agriculture to manufacturing. In order to prevent this disparity from culminating in serious social and political instability, policies have been reoriented toward supporting the income of farmers. At the same time, governments in middle-income countries must continue to...

Autores: Mahabile,   M.; Lyne,   Michael C.; Panin,   A.
This study attempts to identify factors responsible for differences in the productivity of cattle managed by private and communal livestock farmers in the southern region of Botswana during 1999/2000. Sample survey data are used to estimate the parameters of a block recursive regression model. Some of the equations postulated in the model are estimated with two-stage least squares (2SLS) to account for likely correlation between endogenous explanatory variables and the error term. The results show that (a) respondents with secure land tenure (private farms) and larger herds use more agricultural credit than do those who rely on open access communal grazing to raise cattle; (b) secure tenure and higher levels of liquidity from long-term credit and off-farm...

The Internet may reduce constraints on a farmer’s ability to receive and manage information, regardless of where the farm is located or when the information is used. Using a count data estimation procedure, this study attempts to examine the key farm, operator, regional, and household characteristics that influence the number of Internet applications used by farm households. Findings indicate that educational level of the farm operator, farm size, farm diversification, off-farm income, off-farm investments, and regional location of the farm have a significant impact on the number of Internet applications used.

For a representative sample of U.S. consumers, we rank, correlate and explain ratings of concern toward eight food production and processing technologies (antibiotics, pesticides, artificial growth hormones, genetic modification, irradiation, artificial colors/flavors, pasteurization, and preservatives).  Concern is highest for pesticides and hormones, followed by concern toward antibiotics, genetic modification and irradiation.  We document standard relationships between many demographic, economic and attitude variables and the average concern level.  Our main contribution is modeling relative levels of concern across technologies, where we find that key personal and household characteristics that yield little explanatory power for average ratings have...

The International Classification of Diseases, 10th edition (ICD-10) defines atypical bulimia nervosa (ABN) as an eating disorder that encompasses several different syndromes, including the DSM-IV binge eating disorder (BED). We investigated whether patients with BED can be differentiated clinically from patients with ABN who do not meet criteria for BED. Fifty-three obese patients were examined using the Structured Clinical Interview for DSM-IV and the ICD-10 criteria for eating disorders. All volunteers completed the Binge Eating Scale (BES), the Beck Depression Inventory, and the Symptom Checklist-90 (SCL-90). Individuals fulfilling criteria for both ABN and BED (N = 18), ABN without BED (N = 16), and obese controls (N = 19) were compared and contrasted....

An Empirical Examination of Real Options and the Timing of Land Conversions
Provedor de dados: 31
Autores: Towe,   Charles A.; Nickerson,   Cynthia J.; Bockstael,   Nancy E.
Many studies have examined the effects of land use regulations on land prices and urban spatial form.  Increasingly, jurisdictions have adopted incentive based mechanisms, such as purchase of development rights (PDR) programs, to manage the pace and pattern of urban growth and the conversion of agricultural land.  PDR programs provide a third option to landowners in urbanizing areas:  in addition to deciding whether to develop or not, landowners can decide whether to preserve their land.  To our knowledge no studies have explored how the existence of an option to participate in a PDR program affects landowners' development decisions.  This research provides empirical evidence of a previously untested prediction of real options theory:  that additional...

Autores: Ngwenya,   P.; Hassan,   Rashid M.
Economists and statisticians constructing the national income accounts usually overlook the many benefits derived by communities from natural forests and woodlands. This study attempted to impute a value for the ecosystem services of these resources in Swaziland employing an environmental accounting framework. The current measure of national income was found to underestimate GDP by 2% and under value national savings by 10% by not accounting for the flow and asset values of natural forests and woodlands. The study also revealed a very high dependence of the rural communities in Swaziland on natural forests and woodlands for their livelihoods as they derive more than 50% of the value of total household consumption expenditure from these resources.

Autores: REZENDE,ENRICO L.; GOMES,FERNANDO R.; GHALAMBOR,CAMERON K.; RUSSELL,GREGORY A.; CHAPPELLl,MARK A.
How complex physiological systems evolve is one of the major questions in evolutionary physiology. For example, how traits interact at the physiological and genetic level, what are the roles of development and plasticity in Darwinian evolution, and eventually how physiological traits will evolve, remains poorly understood. In this article we summarize the current frame of work evolutionary physiologists are employing to study the evolution of physiological adaptations, as well as the role of developmental and reversible phenotypic plasticity in this context. We also highlight representative examples of how the integration of evolutionary and developmental physiology, concomitantly with the mechanistic understanding of physiological systems, can provide a...

An Ex post Evaluation of Economic Impacts of Foot-and-Mouth Disease on Taiwan Using a Dynamic Computable General Equilibrium Model
Provedor de dados: 31
Autores: Hsu,   Shih-Hsun; Lee,   Duu-Hwa; Chang,   Ching-Cheng; Lin,   Hsing-Chun; Yang,   Tzu-Chiang.
The outbreak of foot-and-mouth disease (FMD) in 1997 has resulted in significant losses to Taiwan's hog industry which was the most important industry in Taiwan's agricultural sector at that time.  Hog farmers have suffered great losses due to the cost of slaughtering infected hogs and reduced revenues in the hog market.  Furthermore, all pork exports are prohibited according to the Office International des Epizooties (OIE) regulation.  There have been a number of ex ante studies that have quantified the potential impacts of FMD on Taiwan's economy (e.g., Tsai 1999, Lin and Hsu 1999).  That is, the potential impact assessment was done when the event of FMD just broke out. This article provides an ex post economy-wide assessment of the FMD impacts on...

AN EXPERIMENTAL INVESTIGATION OF ALTERNATIVE INCENTIVE SCHEMES WITH HETEROGENEOUS AGENTS
Provedor de dados: 31
Autores: Wu,   Steven Y.; Roe,   Brian E.; Sporleder,   Thomas L.; Nazaryan,   Natalie.
Experimental economics is used to compare tournaments (T) and fixed performance contracts (F) when agents have heterogeneous costs. Results suggest that: (1) There is no difference in average pooled effort across contracts, (2) high ability agents exert higher effort than low ability agents under both types of contracts, (3) average pooled earnings are affected by contract type, (4) high ability agents benefit from T whereas low ability agents are harmed by T, and (5) the difference in average pay between high and low ability agents is larger under T.  Thus, T implement greater inequality.

An Experimental Investigation of Willingness to Pay for Non-GM and Organic Food Products
Provedor de dados: 31
Autores: Gifford,   Katie; Bernard,   John C.; Toensmeyer,   Ulrich C.; Bacon,   J. Richard.
The appearance and rapid adoption of genetically modified (GM) foods and the strong growth in organic foods are two of the major trends that have influenced the food system over the past several years.  The purpose of this research was to determine consumer willingness to pay (WTP) for non-GM and organic foods relative to conventional foods and to see if WTP differences between the three categories vary between fresh and processed food products.  Experimental auctions with 133 subjects from three states (Delaware, Maryland, and Pennsylvania) were conducted.  Tobit models were run with the bids as functions of demographic and knowledge and attitude variables.  Results suggest an untapped market exists for non-GM products at a substantial premium over...

An Exploration of Factors Influencing Ethical and Unethical Behavior in Negotiations
Provedor de dados: 31
Autores: Perry,   Gregory M.; Duffy,   Patricia A.; Nixon,   Clair J.; Robison,   Lindon J.
The issue of ethics has received little notice in agricultural economics journals.  This study utilized a survey technique to reveal the ethical attitudes among some 500 students at four Land Grant Universities. The data were analyzed using multiple regression techniques. Individuals negotiating with strangers were more willing to use questionable ethical tactics. Women, individuals who were cooperative rather than competitive in negotiation situations, and those who regularly attended religious services wer consistantly less willing to use questionable ethics in negotiation. The size of the individual's hometown and family income had no clear impact on ethical attidutes in regotiations.

An Exploration of Market Pricing Efficiency: The Dairy Options Pilot Program
Provedor de dados: 31
Autores: Buschena,   David E.; McNew,   Kevin.
Put options have been recommended as a substitute for price support programs (Gardner, 1977), and subsidized option purchases have received some support in lieu of subsidized insurance programs.  Put options are an interesting alternative to price supports because their market-determined price levels allow for flexibility and adjustments to relevant current and expected market conditions.   One difficulty with the use of put options as a substitute for commodity price supports is the relative thinness of these options markets for some commodities.  Market thinness is defined here as the absence of traders willing to take the necessary opposite position in the market in lieu of a relatively large price premium, particularly for a large number of contracts....

An hydrodynamic shear instability in stratified disks
Provedor de dados: 5
Autores: Dubrulle, B; Marie, Louis; Normand, C; Richard, D; Hersant, F; Zahn, Jp.
We discuss the possibility that astrophysical accretion disks are dynamically unstable to non-axisymmetric disturbances with characteristic scales much smaller than the vertical scale height. The instability is studied using three methods: one based on the energy integral, which allows the determination of a sufficient condition of stability, one using a WKB approach, which allows the determination of the necessary and sufficient condition for instability and a last one by numerical solution. This linear instability occurs in any inviscid stably stratified differential rotating fluid for rigid, stress-free or periodic boundary conditions, provided the angular velocity Omega decreases outwards with radius r. At not too small stratification, its growth rate...

This paper describes an efficient bacterial transformation system that was established for the preparation of competent cells, plasmid preparation, and for the storage in bacterial stocks in our laboratory. Using this method, a number of different plasmids have been amplified for further experiments. Competent cells for bacterial transformation were prepared by the calcium chloride method with an optimum concentration of 75 mM. Three different strains of Escherichia coli that were tested are DH5&amp;#945;, TG1 and XL1 blue, and the most efficient strain being XL1 blue. The optimal optical density (OD600) range for competent cell preparation varied for each of the strains investigated, and for XL1 blue it was 0.15-0.45; for TG1 it was 0.2-0.5; and for...

An Information Economic Rationale for Cooperatives
Provedor de dados: 31
Autores: Boetoft,   Peter.
We consider how to organize the processing and marketing of an agricultural product when farming costs are known only by the individual farmers. We show that when marginal costs are un-correlated, the market for …nal goods is competitive, and the market for processing is non-competitive, the socially optimal production levels are sustained by a cooperative and a cooperative only. We show also that the cooperative form is particularly useful when the cost uncertainty is large and the net average revenue product is small.

This paper analyses the networks of production, marketing, and consumption of organics products understood as specific quality products, using an interdisciplinary approach to understand how institutions are constructed, how standards and rules are established and implemented, and which values and habits are negotiated, enforced, and regulated. Governments and Civil Society are both important for coordinating the organic agrifood systems, given the diversity of cultures, ideas, policies, territories, habits and regulatory systems. Transaction Costs Theory, French Convention Theory, Social Network Analyses, and Actor-Network Theory are all approaches that help to analyse the diversity of relations established between actors in agrifood systems designed to...

An Inverse Almost Ideal Demand System of Fresh Tomatoes in the U.S.
Provedor de dados: 31
Autores: Grant,   Jason H.; Foster,   Kenneth A.
Previous studies of fresh market tomatoes in the U.S. have focused on the supply side and welfare effects of NAFTA. Very few studies have focused on the demand side, however, because fresh tomatoes do not have any close substitutes. In this study we draw on the fact that Mexican and Canadian fresh tomatoes may be close substitutes to U.S. fresh tomatoes. An Inverse Almost Ideal Demand System of the NAFTA fresh tomato market is estimated where fresh tomatoes differ by country of origin.  The results indicate that NAFTA tomatoes are substitutable but the degree of substitutability varies widely depending on the season. Quantity changes in the U.S. fresh tomato market can result in significant retail price changes. This study has specific policy implications...

An Investigation of Production Risk, Risk Preferences and Technical Efficiency: Evidence From Rainfed Lowland Rice Farms in the Philippines
Provedor de dados: 31
Autores: Villano,   Renato A.; O'Donnell,   Christopher J.; Battese,   George E.
Risk plays a vital role in farmers' decisions on input allocations and, therefore, output supply.  This paper provides empirical evidence on the estimation of production risk, risk preferences and technical inefficiency.  An eight-year panel data set is used for 46 rice farmers from a representative rainfed lowland environment in Central Luzon, Philippines.  The heteroskedastic and stochastic frontier frameworks are reconciled and extended to accommodate the risk preferences of farmers in an analysis of production risk.  Results show that technical inefficiency is overstated in risky production environments where farmers are risk-averse.

An Investigation of Voluntary Discovery and Disclosure of Environmental Violations Using Laboratory Experiments
Provedor de dados: 31
Autores: Murphy,   James J.; Stranlund,   John K.
This paper uses laboratory experiments to test individual responses to policies that seek to encourage firms to voluntarily discover and disclose violations of environmental standards. We find that while it is possible to motivate a significant number of voluntary disclosures without adversely affecting environmental quality, this result is sensitive to both the fine for disclosed violations and the assumption that firms know their compliance status without cost.  When firms have to expend resources to determine their compliance status, motivating a significant number of violation disclosures yields worse environmental quality. Finally, relative to conventional enforcement, disclosure polices will result in more violations being sanctioned, but fewer of...

An Investment Analysis Approach to Examining Bio-Control of Invasive Weeds
Provedor de dados: 31
Autores: Smith,   Elwin G.; Young,   Douglas L.
Invasive weeds are a large problem on large tracts of rangeland in North America. Biological methods of control have been instituted, but many information gaps remain. An investment model approach is used to demonstrate some of the potentially key pieces of biological data that are required for an analysis. This model is applied to the control of leafy spurge on rangeland. The results of control are very dependent on the rate of spread and control by the biological control agent, the initial density of the weed, and the recovery of the forage (grass) after the weed has been controlled. Benefits of control are relatively low, as is the cost of the biological control practice. It takes several years before net benefits of the control practice are positive.

The bacteriological and clinical efficacy and the safety of gatifloxacin for the treatment of non-complicated acute rhinosinusitis was evaluated in 49 adult patients in an open-label multicenter study in Brazil. Patients under age 18, or with associated systemic diseases, were excluded. Diagnosis was based on symptoms, otorhinolaryngological examination, and X-rays of the sinus. At the first visit, all patients were treated with a single daily dose of 400 mg gatifloxacin for 10 days. Middle nasal meatus secretion was collected and sent for culture before and after treatment. Patients were all reevaluated at days 3 to 5; days + 1 to + 5 and 18 to 25 days + 7 to + 14 . Ninety three percent of the patients were considered clinically cured at the end of the...

An Operational Approach for Evaluating Investment Risk: An Application to the No-Till Transition
Provedor de dados: 31
Autores: Upadhyay,   Bharat Mani; Young,   Douglas L.
Roy's safety-first rule is used to provide measures popular with farmers of short and long term business risk associated with various no-till transition strategies over an investment horizon. The short run rule provided more sensitivity to inter-year financial risk than other commonly used criteria. Results revealed that speed of adoption influenced the probability of successful transition more than did the sequence of drill acquisition methods. Higher equity and larger farms had a greater chance of transition success. Slow acreage expansion with a custom or rental drill reduces risk until a no-till yield penalty is eliminated.

An Ordered Tobit Model of Market Participation: Evidence from Kenya and Ethiopia
Provedor de dados: 31
Autores: Bellemare,   Marc F.; Barrett,   Christopher B.
Do rural households in developing countries make market participation and volume decisions simultaneously or sequentially? This article develops a two-stage econometric model that allows testing between these two competing hypotheses regarding household-level market behavior. The first stage models the household's choice of whether to be a net buyer, autarkic, or a net seller in the market. The second stage models the quantity bought (sold) for net buyers (sellers) based on observable household characteristics. Using household data from Kenya and Ethiopia on livestock markets, we find evidence in favor of sequential decision-making, the welfare implications of which we discuss.

Autores: Zacks,Michele A.; Wen,Jian-Jun; Vyatkina,Galina; Bhatia,Vandanajay; Garg,Nisha.
There is growing evidence to suggest that chagasic myocardia are exposed to sustained oxidative stress-induced injuries that may contribute to disease progression. Pathogen invasion- and replication-mediated cellular injuries and immune-mediated cytotoxic reactions are the common source of reactive oxygen species (ROS) in infectious etiologies. However, our understanding of the source and role of oxidative stress in chagasic cardiomyopathy (CCM) remains incomplete. In this review, we discuss the evidence for increased oxidative stress in chagasic disease, with emphasis on mitochondrial abnormalities, electron transport chain dysfunction and its role in sustaining oxidative stress in myocardium. We discuss the literature reporting the consequences of...

An Overview of Phytosanitary Risk Aspects of Composting by Organic Farmers
Provedor de dados: 21
Autores: Termorshuizen, Aad J.; Blok, Wim J.
Usage of compost in agriculture always brings about the risk of introducing plant pathogens. By proper composting, resulting in high temperatures during the thermophilic phase, compost can be applied safely. Organic farmers often prefer to compost organic residues themselves. The advantage of such an approach is that no material of foreign origin is introduced, but a drawback is the smaller scale of composting, which brings about greater phytosanitary risks. These risks can be dealt with by increasing the composting duration and by proper turning of the compost heap. If only organic residues from farms are composted, this usually results in low-quality composts because of the low lignin contents. Therefore, addition of materials that are high in lignin,...

During the spring and summer of 2002, an outbreak of low-pathogenic H7N2 avian influenza virus (AIV) infected 210 flocks of chickens and turkeys in Virginia, West Virginia and North Carolina, and caused the destruction of more than 4.7 million birds. Although no epidemiologic link was established, the virus was related to the H7N2 virus circulating in the live-bird market system (LBMs) since 1994. An avianinfluenza Task Force (TF), comprised of industry, state and federal personnel, was utilized in the control programme. The use of good safety and biosecurity practices was emphasized by TF commanders. Carcass-disposal options, which included burial in sanitary landfills, incineration and composting, proved to be problematic and caused delays in...

Autores: Dallabrida,Ademar Luiz; Schossler,João Eduardo; Aguiar,Eduardo Santiago Ventura de; Amendola,Gustavo Frassetto; Silva,José Henrique Souza da; Soares,José Mario Doleys.
O presente trabalho teve como objetivo comparar ex vivo, em 12 pares de ossos, a ação das forças de compressão axial e de flexão em dois métodos de fixação de fratura diafisária transversal em fêmur de cães com peso entre 5 e 10kg. Um com a utilização de dois pinos intramedulares de Steinmann de 2,0mm de diâmetro e outro com a utilização de um método de transfixação cortical interna com pinos de Steinmann de 2,0mm de diâmetro, de forma que os mesmos formem uma tala ao redor do osso e fixando-os com fios de aço inoxidável de 0,6mm de diâmetro em cerclagem. Os ossos fraturados e estabilizados após redução dos fragmentos, foram submetidos às forças em uma prensa Soloteste®, sendo que os do grupo G2 (transfixação esquelética interna) apresentaram superioridade...

Análise clínica, radiológica, macroscópica e histológica do úmero de codornas domésticas (Coturnix japonica), submetido ao implante da poliuretana derivada do polímero de mamona (Ricinnus communis)
Provedor de dados: 65
Autores: Bolson,Juliano; Schossler,João Eduardo; Ornes,Roberta Caroline; Mottin,Vanessa; Alberti,Thiago.
Na cirurgia ortopédica, são freqüentes as situações em que o cirurgião se depara com grandes perdas ósseas, provocadas especialmente por traumatismos de alta energia, tumores ou infecções. A reparação dessas fraturas requer grande conhecimento a respeito de materiais que possam ser utilizados para preencher essas falhas. Esses materiais podem ser derivados biológicos, sintéticos ou metálicos. Dentre eles, destacam-se os enxertos ósseos e os implantes de biomateriais. Com o aumento dos animais exóticos, utilizados como animais de estimação, a casuística clínica e cirúrgica dessa especialidade vem crescendo, tanto em clínicas quanto em hospitais veterinários. Particularmente, as aves constituem a maioria desses animais, e entre seus problemas cirúrgicos as...

Análise comparativa da variabilidade patogênica de Uromyces appendiculatus em algumas regiões brasileiras
Provedor de dados: 102
Autores: Souza,Thiago Lívio P. O. de; Alzate-Marin,Ana Lília; Moreira,Maurilio A.; Barros,Everaldo G. de.
A ferrugem do feijoeiro comum (Phaseolus vulgaris), incitada pelo fungo Uromyces appendiculatus, é uma das mais importantes doenças que afetam essa cultura. Trabalhos anteriores demonstraram a ampla variabilidade patogênica de U. appendiculatus no Brasil. No entanto, o uso de distintos grupos de cultivares diferenciadoras em tais trabalhos dificulta a análise comparativa e a identificação de fontes de resistência de amplo espectro. Assim, os objetivos deste trabalho foram: 1) caracterizar sete isolados de U. appendiculatus, coletados em diferentes regiões do estado de Minas Gerais, frente às 19 cultivares diferenciadoras para ferrugem, adotadas no "The Bean Rust Workshop", realizado em 1983, em Porto Rico, e 2) comparar os padrões de...

Análise comparativa do meio físico e socioeconômico de três municípios com parques florestais: Araponga, Caparaó e São Roque de Minas - MG.
Provedor de dados: 14
Autores: COSTA, T. C. e C. da; COSTA, L. M. da.
O meio físico, a localização geográfica, e a história de ocupação de um município contribuem na sua socioeconomia. Do mesmo modo, limitações físicas naturais resultam em pouca alteração antrópica, protegendo áreas que podem vir a ser transformadas em unidades de conservação, sob leis de proteção ambiental. Estas áreas, como por exemplo, parques florestais, apresentam potencial turístico, como uma alternativa socioeconômica. Este trabalho é uma análise comparativa de informações municipais socioeconômicas, históricas e do meio físico, com o objetivo de investigar uma possível influência de parques florestais na socioeconomia de municípios do Estado de Minas Gerais que contém grande parte de suas áreas com topografia acidentada e altitude elevada.

Análise de dados de produção em um pomar jovem de laranjeiras Hamlin: I. Relações com a resposta espectral
Provedor de dados: 94
Autores: Parise,Francisco José de Oliveira; Vettorazzi,Carlos Alberto.
Em um pomar jovem de laranjeiras Hamlin, não-irrigado, foi realizado um estudo que procurou investigar a potencialidade do uso de dados espectrais de árvores, visando ao gerenciamento localizado da produção de 52 árvores, distribuídas ao longo de duas transeções cruzadas, selecionadas para o levantamento da produção em dois ciclos sucessivos, 2000-2001 e 2001-2002. Imagens aéreas multiespectrais de alta resolução espacial foram tomadas de um pomar, em duas fases fenológicas distintas: antes e após a fase de desenvolvimento vegetativo. Os índices de vegetação NDVI e SAVI e os níveis de cinza nas faixas espectrais do vermelho e do infravermelho foram relacionados com a produção por meio de regressões. Os resultados mostraram que a resposta espectral...

Análise de dados de produção em um pomar jovem de laranjeiras Hamlin: II. classificação de dados espaço-temporais
Provedor de dados: 94
Autores: Parise,Francisco José de Oliveira; Vettorazzi,Carlos Alberto.
Em um pomar jovem de laranjeiras Hamlin, não-irrigado, foi realizado um estudo que procurou investigar a potencialidade da utilização de dados espaço-temporais de produção por árvore para o gerenciamento localizado. A produção de 1.471 árvores georreferenciadas foi levantada em dois ciclos sucessivos, 2000-2001 e 2001-2002, e classificada por meio de uma análise de agrupamentos via lógica fuzzy. Ainda, foi realizada uma análise de correlação intraclasse com dados de resposta espectral de 52 árvores, extraída de imagens aéreas multiespectrais de alta resolução espacial. Os resultados mostraram que foi possível a formação de classes distintas de comportamento produtivo, em função dos padrões de variabilidade espacial e temporal da produção. No entanto, as...

Análise de diferentes sistemas de iluminação para aviários de produção de ovos férteis
Provedor de dados: 91
Autores: Jordan,Rodrigo A.; Tavares,Maria H. F.
Excluindo-se a ração, o insumo mais utilizado na cadeia produtiva da avicultura é a energia elétrica, principalmente na produção de pintinhos de um dia, ocorrendo consumo em todas as fases, desde a obtenção do ovo até a incubação. Para a produção do ovo consome-se grande quantidade de energia elétrica nos sistemas de iluminação dos aviários, devido à necessidade de exposição da poedeira à luz no comprimento de cor amarela. A redução dos gastos com energia elétrica está ligada à melhoria dos sistemas de iluminação, já que o sistema usual é formado por lâmpadas incandescentes de grande potência, baixa eficiência e vida útil curta. Assim, através deste trabalho, desenvolvido em uma granja do Sudoeste do Paraná, objetivou-se desenvolver um sistema de...

Análise de imagens na avaliação da qualidade de sementes de milho localizadas em diferentes posições na espiga
Provedor de dados: 95
Autores: Mondo,Vitor Henrique Vaz; Cicero,Silvio Moure.
A análise de imagens, para avaliar a qualidade de sementes, é um método de precisão que possibilita examinar, com detalhes, a região danificada ou alterada, sua localização e extensão. Por ser um método não destrutivo, as sementes em análise podem ser submetidas a testes fisiológicos e, desta forma, é possível estabelecer as relações de causa e efeito. Assim, a pesquisa teve o objetivo de estudar os efeitos de diferentes posições da semente de milho na espiga, sobre a qualidade, utilizando-se a técnica de análise de imagens. Para tanto, as espigas do cultivar DKB 212 foram debulhadas de maneira que pudessem ser isoladas as sementes das posições proximal, intermediária e distal. As sementes foram caracterizadas fisicamente e avaliadas quanto ao vigor e...

Análise de métodos de estimativa de evapotranspiração na otimização de sistemas de drenagem
Provedor de dados: 91
Autores: Silva,Késia O. da; Miranda,Jarbas H. de; Duarte,Sergio N.; Folegatti,Marcos V.
Inúmeros são os métodos para se estimar a evapotranspiração potencial (ETP) em que os mais simplificados apresentam limitações quanto à precisão dos resultados obtidos e os mais complexos apontam a dificuldade de se dispor de todos os dados necessários ao cálculo. No presente trabalho, compararam-se os métodos de Thornthwaite e Camargo com o de Penman-Monteith, tomado como padrão, com o objetivo de se verificar qual a influência da utilização de cada método na estimativa da ETP diária sobre o dimensionamento econômico de um sistema de drenagem, utilizando-se o modelo SISDRENA. Pelos resultados obtidos concluiu-se que as diferenças entre os métodos não afetaram significativamente a obtenção do espaçamento econômico entre drenos.

Três formas de análise espacial foram comparadas à análise do modelo linear Gauss-Markov normal em experimentos de Genética, tendo-se suposto os efeitos de progênies como aleatórios: médias móveis nos dados brutos (MM), médias móveis nos dados residuais (Papadakis - PPD) e análise espacial por meio de modelagem de covariâncias residuais (AE). Inicialmente, ignorou-se a informação do controle local, para testar a efetividade da análise espacial. Posteriormente, foi verificado se haveria melhoras com as diferentes formas de análise espacial aplicadas ao modelo completo, considerando-se o controle local do delineamento em látice. Os valores médios de razões, entre estimativas de componentes de variância e de herdabilidade, foram usados como guia de discussão...

O mel de abelhas é um produto muito apreciado, no entanto, de fácil adulteração com açúcares ou xaropes. Desta forma, é necessário que haja algumas análises para a determinação da sua qualidade para que seja comercializado. Este trabalho teve como objetivo fazer a análise físico-química dos méis de abelha Apis mellifera. e Melipona scutellaris para a comparação entre as espécies e entre as localidades do Brejo e do Cariri (regiões do Estado da Paraíba). Observou-se que o mel de abelha nativa apresenta um maior teor de água (umidade de 25,25%) quando comparado com o mel de abelha africanizada (18,76%), dificultando o seu armazenamento, pois o alto teor de água do produto diminui a sua vida útil de prateleira. Para as análises de hidroximetilfurfural, o...

Análise micro-histológica da composição botânica de misturas preestabelecidas, submetidas ao processo de digestão in vitro
Provedor de dados: 96
Autores: Bauer,Maristela de Oliveira; Gomide,José Alberto; Silva,Eldo Antônio Monteiro da; Regazzi,Adair José; Chichorro,José Franklim.
A composição botânica de misturas preestabelecidas de seis espécies forrageiras foi estimada após diferentes tempos de digestão in vitro e comparadas com a composição real. Três misturas de seis espécies, com participações conhecidas, foram constituídas nos períodos chuvoso e seco e examinadas pela técnica micro-histológica. O período de amostragem interferiu na estimativa de apenas uma das misturas. Apesar das diferenças estatísticas entre a composição real das misturas e suas estimativas, nos períodos, seus índices de similaridade foram superiores a 85%. O tempo de digestão influenciou nas estima­tivas das misturas, dependendo da porcentagem de participação das espécies. As estimativas foram idênticas para as três misturas após 48 e 72 horas de digestão....

Análise quantitativa e distribuição de populações de espécies de Anastrepha (Diptera: Tephritidae) no campus Luiz de Queiroz, Piracicaba, SP
Provedor de dados: 82
Autores: Uramoto,Keiko; Walder,Julio M.M.; Zucchi,Roberto A.
A distribuição das fêmeas das espécies de Anastrepha por armadilha foi fortemente agregada, com cinco armadilhas (6%) capturando 50% do total de fêmeas. Apenas Anastrepha fraterculus (Wied.) e A. obliqua (Macquart) foram dominantes. A. fraterculus foi a espécie mais freqüente (80,2% das fêmeas) e a mais constante, ocorrendo em 98,0% das amostras. Em ordem decrescente de freqüência, seguiram-se A. obliqua (12,6%), A. pseudoparallela (Loew) (3,1%) e A. bistrigata Bezzi (2,1%). As demais espécies apresentaram freqüência menor que 1%. O valor elevado do índice de Simpson (0,660) e os valores baixos do índice de Shannon (0,7518) e de eqüitatividade (0,4597) resultaram da alta freqüência de A. fraterculus.

Analisis de convergencia en productividad agraria en las regiones europeas
Provedor de dados: 31
Autores: Valero,   Juan Sebastian Castillo; Cuerva Narro,   Maria Carmen.
RESUMEN: En este artículo se estudia la convergencia regional desde un punto de vista sectorial, centrada en el sector agrario. En el desarrollo del mismo se hace eco de la relevancia del sector agrario para una explicación histórica de las desigualdades territoriales en la Unión Europea y se analiza la evolución de la desigualdad y la convergencia de las agriculturas en las regiones europeas durante el periodo 1985-1997 a través del valor añadido agrario por ocupado. La existencia de un proceso de convergencia a niveles absolutos entre las economías regionales agrarias es un hecho constatado en el análisis. Sin embargo, las peculiaridades específicas de cada territorio hacen que no podamos hablar de una posición de equilibrio común, sino que las...

Analisis de escenarios de políticas para la gestion publica en la agricultura de regadio
Provedor de dados: 31
Autores: Riesgo,   Laura; Gomez-Limon,   Jose Antonio.
En este trabajo se presenta un enfoque metodológico para el análisis de presiones e impactos de la aplicación conjunta de diferentes escenarios de política agraria y de tarifación del agua de riego. Para alcanzar dicho objetivo se asume que los agricultores consideran distintos criterios en la gestión de su actividad productiva. En este contexto decisional se utilizan modelos de programación matemática basados en la Teoría de la Utilidad Multiatributo (MAUT), de modo que pueda simularse el comportamiento de los agricultores en el futuro. Como resultado de dicha simulación no sólo se obtienen las variables de decisión de los agricultores (planes de cultivos), sino también un conjunto de indicadores económicos, sociales y ambientales que serán de utilidad...

Análisis del Voltinismo y la Diapausa en Poblaciones de Apagomerella versicolor (Coleoptera: Cerambycidae) en el Gradiente Latitudinal de su Distribución en la Argentina
Provedor de dados: 99
Autores: Logarzo,Guillermo; Gandolfo,Daniel E.
RESUMEN. Apagomerella versicolor es un cerambícido cuyas larvas barrenan los tallos de plantas compuestas de los géneros Xanthium, Ambrosia y Pluchea (Asteraceae). En la Argentina se distribuye entre los 25º y 39º de LS. Estudios sobre la biología de este insecto realizados con poblaciones de los alrededores de Buenos Aires (35º S), indicaban que era una especie univoltina con diapausa larval durante el invierno y que se podía inducir la salida del estado de diapausa exponiendo las larvas a bajas temperaturas. Sin embargo algunas observaciones sugerían que poblaciones del norte del país podían ser bi o multivoltinas sin diapausa larval. En este trabajo estudiamos el voltinismo y la diapausa en una clina latitudinal entre los 25 y los 32º de LS. Se realizó...

SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

An optimal supply of dairy cows with energy and nutritive substances is just as important for the organic as it is for the conventional milk production. The current project examined if in organic rural economy the feeding meets the required demand. In the trial period from 10 Nov. 2001 till 17 Oct.2003 data of the milk performance test were gathered for 11 capacity control days. The energy and nutritive substance made a silage food capacity of 17 -24 kg milk per cow and day possible, so a milk capacity of 8157 kg milk per cow and year could be realized. A suspected shortage of nitrogen based on the low milk urea concentration caused by the normal milk protein concentration could not be confirmed. The result of the capacity control showed that only     76 %...

Analysing drought impacts and recovery options by adapting a dairy farming systems modelling approach
Provedor de dados: 31
Autores: Armstrong,   Dan P.; Ho,   Christie K.M.; Doyle,   Peter T.; Malcolm,   Bill; Gibb,   I.; Brown,   Stuart.
The dairy industry in northern Victoria faced dramatic changes between 2001/02 and 2002/03. Drought resulted in a substantial decrease in availability, and subsequent increase in price, of irrigation water and supplementary feed. Most farms recorded substantial net cash flow deficits. Prior to 2002/03, a project had been established using case studies and a spreadsheet model to examine potential futures for different farm types. This approach was successfully adapted to examine drought impacts and recovery options under the vastly different prevailing circumstances. Several factors appear to have contributed to the adaptability of the approach, as follows: • The approach considered many aspects of farm management systems, but was simple enough to allow...

Analysing Family Farm Succession: A Probit and a Competing Risk Approach
Provedor de dados: 31
Autores: Glauben,   Thomas; Tietje,   Hendrik; Weiss,   Christoph R.
The present study examines family and farm characteristics affecting the choice and the timing of intergenerational farm transfers. Using survey data which are linked to accounting data for 272 farms in Northern Germany, we use a probit approach to examine whether specific farm and family characteristics are related to the likelihood of succession within a given period. We go beyond the existing literature by applying a competing risk approach to study the process and thus the timing, respectively of the two competing events – succession or exit from farming. We find that farm characteristics significantly influence succession considerations to the extent that they affect the value of the farm for the potential successor.

Analysing Farmers' Decision-Making Process Face to the Mid-Term Review of the Common Agricultural Policy in the Alentejo region of Portugal
Provedor de dados: 31
Autores: Serrao,   Amilcar; Coelho,   Luis.
This paper describes an experiment that was carried out in order to examine the decision making process of farmers in the Alentejo dryland region of Portugal.  Cumulative  Prospect Theory allows modeling the Alentejo dryland farmers' decision process, because when they decide what crops and livestock activities will produce the different results are appraised relatively to the initial wealth, which permits its appraisal in terms of gains and of losses. An inquiry is developed to study the Alentejo dryland farmers' preferences, which intend to determine risk preferences through a set of games. A discrete sequential stochastic programming model is developed to examine farmers' decision-making process face to the mid-term review of the Common Agricultural...

Russian dairy enterprises underwent dramatic changes during 1990-2001. Not much is known about the position of these enterprises under the new conditions. This study examined a sample group of dairy enterprises in the Moscow region to try to identify similarities and divergences in historical background, performance, managerial and structural characteristics.  A unique farm-level data set from 1990-2001 was used. Assessment of historical characteristics revealed that the currently most successful enterprises were those which in pre-reform years had already shown better economic performance. These farms also had, for the period studied, smaller percentages of reduced resources, no severe debt problems, and better overall management.

In this paper we analyse wine demand in Italy using microdata. Instead of estimating a traditional parametric model (like AIDS) we employed artificial neural networks (ANN) and evaluate the elasticities using two different methods, specific for the non parametric framework. We compared the performances of the two methods to estimate elasticities and put in evidence the relevance of some demographic variables together with the usual economic ones, explaining the consumer's behaviour.

Meeting the food needs of the world’s growing population while reducing poverty and protecting the environment is a major global challenge. Genetically modified crops appear to provide a promising option to deal with this challenge. However there is a need to make strategic decisions on how to spend limited agricultural research funds in order to achieve a maximum impact with regard to finding sustainable solutions to end hunger and poverty. In international development institutions, there is growing interest in the potential use of Strategic Environmental Assessment (SEA) as part of a research based Environmental Management System (EMS) to promote mainstreaming of environmental considerations in policy development. SEA was developed as an approach to...

Analysis of a herpetofaunal community from an altered marshy area in Sicily; with special remarks on habitat use (niche breadth and overlap), relative abundance of lizards and snakes, and the correlation between predator abundance and tail loss in lizards
Provedor de dados: 16
Autores: Luiselli, L.; Angelici, F.M.; Di Vittorio, M.; Spinnato, A.; Politano, E.
A field survey was conducted in a highly degraded barren environment in Sicily in order to investigate herpetofaunal community composition and structure, habitat use (niche breadth and overlap) and relative abundance of a snake predator and two species of lizard prey. The site was chosen because it has a simple community structure and thus there is potentially less ecological complexity to cloud any patterns observed. We found an unexpectedly high overlap in habitat use between the two closely related lizards that might be explained either by a high competition for space or through predator-mediated co-existence i.e. the prevention of the competitive exclusion of one lizard over the other. We also found a strong positive correlation between predator...

Analysis of Cardinal and Ordinal Assumptions in Conjoint Analysis
Provedor de dados: 31
Autores: Harrison,   R. Wes; Gillespie,   Jeffrey M.; Fields,   Deacue.
Of twenty-three agricultural economics conjoint analyses conducted between 1990 and 2001, seventeen used interval-rating scales, with estimation procedures varying widely. This study tests cardinality assumptions in conjoint analysis when interval-rating scales are used, and tests whether the ordered probit or two-limit tobit model is the most valid. Results indicate that cardinality assumptions are invalid, but estimates of the underlying utility scale for the two models do not differ. Thus, while the ordered probit model is theoretically more appealing, the two-limit tobit model may be more useful in practice, especially in cases with limited degrees of freedom, such as with individual-level conjoint models.

Analysis of Consumer Food-Handling Practices from Grocer to Home Including Transport and Storage of Selected Foods
Provedor de dados: 31
Autores: Godwin,   Sandria L.; Coppings,   R.J.
Consumers were interviewed about how they purchase, transport, store, and otherwise handle food. Emphasis was placed on handling of cold foods and home refrigeration. More than 70% of consumers took steps to protect cold foods during purchase and transport and more than 90% claimed to put away cold foods first. Only 7% of consumers used coolers to protect cold foods during transport. How consumers stored a variety of foods was determined and evaluated. Few consumers knew their own or correct refrigerator temperature and few had refrigerator thermometers. A second interview and refrigerator checklist were completed in 200 of the consumers'’ homes at least a year later. Researchers judged that circumstances that might allow for cross-contamination existed in...

Autores: B,Jayashree; Ferguson,Morag; Ilut,Dan; Doyle,Jeff; Crouch,Jonathan H.
Peanut is an important legume crop across the world. However, in contrast to most legume crops, groundnut lacks taxonomic proximity to any major model genome. A relatively large number of genomic sequences were generated from groundnut as part of a microsatellite marker development project. In the current study, a total of 1312 sequences were analyzed of which 448 contained microsatellite motifs. All sequences (GenBank Accessions: BZ999351-CC000573) were analyzed after clustering for possible similarity with publicly available sequences from Arabidopsis, Lotus, soybean and Medicago. At least 39% of the sequences analyzed had significant BLAST similarities with sequences from the four databases searched, of which nearly half (47%) found significant...

On the basis of the micro-economic data of the Hungarian FADN system we analysed the role of subsidies in the profitability of farms, we aimed to reveal which types of farming and economic sizes are effected more by subsidies related to efficiency and profitability. The agricultural enterprises' balance of taxes and subsidies counted from the micro-economic data of FADN enterprises was also analysed in the different type of farming categories and economic size classes. Our aim was to find out what types of farms are subsidized and what types are net payers to the central budget. Examining the pre-tax profit we made the conclusion that with the increase of economic size not only the proportion of profitable farms rises, but the profit per size unit...

This article aims to explain the marketing margins in the eco-labeled products market in Thailand and the Philippines. It focuses on labeled organic agricultural commodities that are commonly exported especially in Europe, which has demand for this type of products. Understanding the interplay of economic variables influencing marketing margins in the eco-labeled market as compared to its conventional counterpart is relevant in understanding how this growing niche market works. The analytical framework developed by Gardner (1975) was used in the analysis to provide a basic understanding of how marketing margins behave. Econometric results show that changes in demand rather than the changes in supply explain most of the variations in margins particularly in...

Analysis of Multiple Structural Breaks in Relative Farm Prices in the United States, 1913-2003
Provedor de dados: 31
Autores: Jin,   Hyun Joung; Miljkovic,   Dragan.
We analyze the movement of farm prices relative to other commodity prices in the period 1913:1-2003:12, investigating the number and time of structural breaks and discussing likely causes of structural breaks in the relative farm prices.  Bai and Perron's (1998, 2003) multiple structural change test with a dynamic programming algorithm is used.  This test makes it possible to have an efficient computation of the estimates of the break points as global minimizers of the sum of squared residuals.  We find 6 structural breaks when we consider only the mean process and 2 breaks when we consider the mean and autoregressive processes.  Possible causes for these breaks are discussed.

Autores: Cardenas,   Gabriela; Vedenov,   Dmitry V.; Houston,   Jack E.
Despite the decline of coffee prices during the 1990s, coffee production remains a main economic activity for producers in Southeastern Mexico. This paper analyzes the coffee production system for 24 municipios, or districts, in Veracruz, Mexico during a five-year cropping period (1997-–2002). A stochastic frontier approach is used in order to estimate an input distance function and evaluate production efficiency during the period. Factors such as coffee quality and access to markets are tested in terms of their effect on efficiency. The results show the production process in these municipios, as measured by technical efficiency, seems to be stable over time despite of price fluctuations in the global market. Production of staple crops (corn) along with...

Autores: Biase,Fernando H.; Garnero,Analia Del V.; Bezerra,Luiz A.F.; Rosa,Arthur J.M.; Lôbo,Raysildo B.; Martelli,Lúcia.
Restriction fragment length polymorphism (RFLP) has been detected at the bovine kappa-casein locus. The polymorphism has been analyzed for its effects in cattle production, mostly for milk traits and even for maternal effect on pre-weaning weights. We used polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) to genotype 408 Nellore animals for the non-silent mutation (Thr/Ile136 and Asp/Ala148) that characterizes the A and B variants of the polymorphism and compared expected progeny difference (EPD) for a maternal effect on 120 and 210 days weights and direct EPD for 120, 210, 450 and 550 day weight between AA and AB animals. The EPD values were obtained from the University of São Paulo (Brazil) Nellore Cattle Breeding Program,...

In this study, cost-effective technological options to stabilize CO2 concentrations at 550, 500, and 450 ppmv are evaluated using a world energy systems model of linear programming with a high regional resolution. This model treats technological change endogenously for wind power, photovoltaics, and fuel-cell vehicles, which are technologies of mass production and are considered to follow the “learning by doing” process. Technological changes induced by climate policies are evaluated by maintaining the technological changes at the levels of the base case wherein there is no climate policy. The results achieved through model analyses include 1) cost-effective technological portfolios, including carbon capture and storage, marginal CO2 reduction costs, and...

Potassium-40 was determined in soil in an area with 40,000 m² situated in the western State of Pernambuco, Brazil. For radiometric measurements, the gamma spectrometry method with a high purity germanium (HPGe) detector was used. Sampling of 78 soil samples has been performed at intervals of 25 m. The specific activities of 40K were calculated based on the photopeak of 1.46 MeV. Values from 541 to 3,572 Bq kg-1 were obtained (mean of 1,827 Bq kg-1). These values allowed the determination of the elemental concentrations as well as the absorbed dose rates in air, 1 m above the ground. The values varied from 1.7 to 11.5% (mean of 6%) and from 23.4 to 154.3 nGy h-1 (mean of 79 nGy h-1), respectively.

Analysis of the Adoption of Irrigation Technologies Under Uncertain Water Availability
Provedor de dados: 31
Autores: Escribano,   Maria Jesus; Calatrava-Leyva,   Javier.
This paper analyses the adoption process of water-conserving irrigation technologies by a risk averse farmer in a context of uncertain water availability. Firstly, it is analytically shown that the increase in water efficiency that the new technology allows results in a decrease in the cost of the effective irrigation water applied, as well as in an increase in both effective water applied and crop production. It is also concluded that the optimal amount of irrigation water applied depends on individual risk preferences of the producer, on the variance and asymmetry of the cost of water applied, and on the elasticity of the marginal productivity of the effective water applied. Lastly, it is theoretically shown that an increase in the level of uncertainty...

Now days in the pig industry as well as in other agro food sectors is the competitiveness that declare the success or failure on the global market. In the case of the pig industry, to be competitive it means to be able to offer a product of higher quality than rivals, but at similar price. The Danish pig industry has reached this level of competitiveness mainly thanks to its forward vertical integrated production chain. This specific coordination, besides than to reduce the transaction costs, push toward a production of excellent quality, that can be promptly adjusted according to the consumers demand.

Provedor de dados: 31
Autores: Renwick,   Alan W.; Revoredo-Giha,   Cesar.
The purpose of the paper is examining the potential implications for the UK sugar beet sector of the EU sugar regime reform. Although the reform has yet to be formalised, the initial proposals centre on price and quota cuts. Using panel data from the Farm Business Survey for England, the paper estimates two cost functions: one for the sugar enterprise and another for the cropping part of the farm (i.e., excludes any livestock enterprise) and use them to analyse the impacts on profitability and costs of three possible reform scenarios: a 25 per cent cut in UK quota, a 25 per cent cut in price, a 40 per cent cut in price. The results show that the largest gains in terms of economic efficiency would be achieved under the 40 per cent price cut; however, the...

There is no universally accepted definition of the category of "rural area" in Hungary and this issue is the subject of controversy. The EU or OECD standards cannot be fully applied due to unique national characteristics. As a) the role of agriculture in the national economy has drastically decreased in the last 15 years in Hungary - due to the political transition and globalisation, and as b) this decreasing importance causes heavy and pressing problems, especially in agricultural and ex-agricultural areas and regions, job loss is a characteristic sign of the underprivileged areas, and that affects mainly the villages and rural people who have lost their jobs in the agricultural sector.

A anatomia do Cebus apella é a lacuna que falta entre prossímios e os macacos do novo mundo. Comparações entre Cebus e humanos são relatadas, dentre outras considerações comparativas em relação a chimpanzés, babuínos, gatos e cães. Oito espécimes de Cebus apella foram doados pelo Instituto Brasileiro de Meio Ambiente e Recursos Naturais Renováveis (Ibama), de Sete Lagoas, Estado de Minas Gerais, Brasil, e sacrificados segundo as recomendações do Colégio Brasileiro de Experimentação Animal (Cobea). Houve equivalência na distribuição e inervação dos nervos do braço de Cebus e humanos, embora se tenha encontrado divergência no trajeto dos nervos mediano e ulnar, que apresentaram maior similaridade com cães e gatos. Estruturas anatômicas inexistentes no homem,...

Anatomia foliar de Maytenus Mol. emend Mol. (Celastraceae), ocorrente no Estado do Rio de Janeiro, Brasil
Provedor de dados: 39
Autores: Joffily,Ana; Vieira,Ricardo Cardoso.
Este trabalho aborda o estudo anatômico de cinco espécies do gênero Maytenus Mol. emend. Mol. (Celastraceae). O gênero é o maior da família, e está representado no Brasil por aproximadamente 80 espécies. Maytenus é um gênero polifilético, necessitando de trabalhos adicionais para nova circunscrição. Maytenus ardisiaefolia Reiss., M. brasiliensis Mart., M. cestrifolia Reiss., M. communis Reiss. e M. obtusifolia Mart. são de difícil identificação, devido à semelhança dos verticilos reprodutivos, e pela variação na forma e no tamanho das folhas. As estruturas anatômicas observadas nas diversas partes da folha mostraram-se muito semelhantes nas espécies estudadas, sendo de valor taxonômico e de provável importância filogenética para o gênero Maytenus.

Autores: Carmello-Guerreiro,Sandra Maria; Paoli,Adelita Aparecida Sartori.
The aim of the present work was to record anatomical data for the fruit and seed of Lithraea molleoides (Vell.) Engl, and compare the results with those for L. brasiliensis and the genera Schinus and Rhus. The L. molleoides fruit was a drupe with a friable and lignified exocarp. The mesocarp was parenchymatous with large secretory canals associated with vascular bundles. The endocarp consisted of four layers: an outer layer of polyhedral cells with prismatic crystals of calcium oxalate, and three inner layers of sclereids in a palisade arrangement. The ovule was anatropous, unitegmic, and crassinucelate. In the chalazal region, a cup-like zone of tanniniferous parenchymal cells formed the hypostase. The developing seed had a circinotropous-like shape, that...

Anbau transgener Pflanzen – Räumliche Aspekte der Koexistenz
Provedor de dados: 21
Autores: Schlatter, Christian; Oehen, Bernadette.
Most of the farmers in Switzerland won’t apply GMO farming. Their organisations support a five-year ban for the marketing of transgenic plants. However, in Switzerland there is no political discussion on co-existence as in the European community and their member states. In this study, the spatial aspects of coexistence of transgenic, conventional and organic farming in Switzerland are investigated. It shows that there are only 28 communities of 2848 where all farmers are bound by different labels to produce GMO-free. Most of these communities are situated in high altitude regions. In contrast, in arable regions of Switzerland, few farmers produce organic crops. In most of the communities in Switzerland, the simultaneous production with and without...

Anelamento e incisão anelar em fruteiras de caroço
Provedor de dados: 65
Autores: Sartori,Ivar Antonio; Ilha,Luciano Larruscahim Hamilton.
O cultivo de pessegueiros é uma atividade de grande importância econômica no Sul do Brasil, e o Estado do Rio Grande do Sul se destaca como o maior produtor brasileiro. Grande parte dos pomares se encontram na Metade Sul do Estado. Um dos principais problemas da cultura para o consumo de frutas in natura é o tamanho reduzido das mesmas e a produção concentrada, que dificultam a comercialização. O anelamento e/ou a incisão anelar de ramos pode ser usada, com o intuito de aumentar a massa média das frutas e antecipar o período de colheita. Esta revisão busca encontrar dados referentes à época de execução, cuidados necessários, problemas associados e aspectos fisiológicos do anelamento e incisão anelar de ramos em fruteiras de caroço, principalmente pêssegos,...

The distinction between Anetholea and Syzygium is lessened due to the occurrence of epigeal germination and dry fruitedness in the latter genus also and it is concluded that Anetholea is better placed within Syzygium. Analysis of sequence data from nuclear ribosomal DNA and the chloroplast genome support this conclusion. The sole species of Anetholea, A. anisata, is transferred to Syzygium and the new combination, S. anisatum (Vickery) Craven &amp; Biffin, made. Syzygium wilsonii subsp. cryptophlebium is reinstated at species rank, necessitating the new combination, S. cryptophlebium (F. Muell.) Craven &amp; Biffin. Two new taxa of Syzygium are described from Australia, S. wilsonii subsp. epigaeum Craven &amp; Biffin and S. maraca Craven &amp; Biffin.

Animal Disease Economic Impacts: A Survey of Literature and Typology of Research Approaches
Provedor de dados: 31
Autores: Pritchett,   James G.; Thilmany,   Dawn D.; Johnson,   Kamina K.
Animal diseases such as bovine spongiform encephalopathy (BSE) are a threat to the animal product marketing sector and the broader economy. Policy makers and industry stakeholders seek a means of assessing a disease threat's economic impacts when evaluating prevention and mitigation measures. But, differences in the focus of the impact analysis (production level, market prices, welfare), level of analysis (geographically, marketing phase) and proposed policy alternatives all influence the analytical approach. This paper surveys previous research, focusing on methodological approaches and results. Drawing from past research and future economic data needs, a typology is developed to guide researchers when defining the scope and policy alternatives of various...

Animal Efficiency in an Intensive Beef Production System
Provedor de dados: 31
Autores: Fleming,   Euan M.; Fleming,   Pauline; Rodgers,   Heidi; Griffith,   Garry R.; Johnston,   David.
A stochastic input distance function is estimated to analyse the efficiency with which physical characteristics of individual lot-fed beef cattle in Australia are combined with conventional inputs to produce a final product possessing defined quality attributes. High mean technical efficiency estimates are reported for all animals and by breed. All partial output elasticities with respect to inputs are of expected sign. Of four outputs included in the analysis, carcass weight and moisture retention in meat after cooking have highly significant coefficients of expected sign, but two meat quality variables have coefficients of unexpected sign indicating that they decline as inputs increase. Some evidence is detected of scope economies between moisture...

Animal Health Policy and Practice: Scaling-up Community-based Animal Health Systems, Lessons from Human Health
Provedor de dados: 31
Autores: Riviere-Cinnamond,   Ana.
In an extensive literature review, the author develops policy recommendations to facilitate scaling up community-based animal health systems to the national level. Noting that human and animal health services in rural areas have much in common, and that an extensive literature studies policy regarding primary healthcare for humans exists, she surveys that literature for observations and conclusions applicable to policy analysis of primary animal healthcare. She notes differences in the history and development of the two delivery systems. The push for human health services came with a worldwide initiative agreed at a high level in 1978. Health for All was set out as a moral imperative, and programmes have been strongly top-down. Delivery of animal health...

Animal-based medicines: biological prospection and the sustainable use of zootherapeutic resources
Provedor de dados: 42
Autores: Costa-Neto,Eraldo M.
Animals have been used as medicinal resources for the treatment and relieve of a myriad of illnesses and diseases in practically every human culture. Although considered by many as superstition, the pertinence of traditional medicine based on animals cannot be denied since they have been methodically tested by pharmaceutical companies as sources of drugs to the modern medical science. The phenomenon of zootherapy represents a strong evidence of the medicinal use of animal resources. Indeed, drug companies and agribusiness firms have been evaluating animals for decades without paying anything to the countries from where these genetic resources are found. The use of animals' body parts as folk medicines is relevant because it implies additional pressure over...

Animal-borne sensors successfully capture the real-time thermal properties of ocean basins
Provedor de dados: 5
Autores: Mcmahon, Cr; Autret, Emmanuelle; Houghton, Jdr; Lovell, P; Myers, Ae; Hays, Gc.
Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to predict and quantify the consequences of this change is severely limited by the paucity of in situ oceanographic measurements. Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem because marine animals range widely across the world's ocean basins and visit remote and often inaccessible locations. However, unlike the information being collected from conventional oceanographic sensing equipment, which has been validated, the data collected from instruments deployed on marine animals over long periods has not. This is the first long-term study to validate in situ...

Anomalous Branching Pattern of Lateral Cord of Brachial Plexus
Provedor de dados: 77
Autores: Das,Srijit; Paul,Shipra.
During routine dissection, an unusual formation of median nerve was detected in the right upper limb of a 55 year old male cadaver. The median nerve had an additional contribution from lateral cord. The two branches of the lateral cord designated as upper and the lower branches were observed at different levels. The upper branch was in close contact with the third part of the axillary artery and it crossed the vessel anteriorly to unite with a branch of the medial cord to form the median nerve. The median nerve thus formed was related medially to the axillary artery (instead of the normal position of being anterolateral). The median nerve descended below and was joined by an additional lower branch from the lateral cord. Interestingly, the ulnar nerve...

For various reasons fruits and vegetables are particularly susceptible to quality losses after harvest and do not satisfy the quality demands of the consumers at purchase. The aim of the project is the optimisation of freshness-preserving provisions along the supply chain such that organic vegetables of regional cultivation reach for the consumer a surplus value through the perceived freshness. Therefore, measurement series were planned which enables the examination of the temperature of selected products along the distribution chain considering spatial and time aspects of the processing steps. Investigation of the overall temperature load allows the estimation of respiration losses by what the degree of quality reduction can be described. This analysis of...

Antagonism of Bacillus spp. against Xanthomonas campestris pv. campestris
Provedor de dados: 52
Autores: Monteiro,Leila; Mariano,Rosa de Lima Ramos; Souto-Maior,Ana Maria.
The antagonism of eight Bacillus isolates was investigated against nine strains of Xanthomonas campestris pv. campestris (causal agent of crucifers black rot) to assess the role of lipopeptides in this process. Antimicrobial and hemolytic (surfactant) activity tests were performed in vitro using agar diffusion methods. Antibiosis and hemolysis were positive for four Bacillus isolates against all X. campestris pv. campestris strains. The correlation observed between antimicrobial and hemolytic activities indicated that lipopeptides were involved in the antibiosis mechanism of the studied antagonists. Fermentation studies were carried out with the isolates that showed highest antimicrobial and hemolytic activities, to follow up growth and production of...

Anthropogenic CO(2) in the Southern Ocean: Distribution and inventory at the Indian-Atlantic boundary (World Ocean Circulation Experiment line I6)
Provedor de dados: 5
Autores: Lo Monaco, C; Metzl, N; Poisson, A; Brunet, C; Schauer, B.
The Southern Ocean, where various water masses are formed ( mode, intermediate, deep, and bottom waters), has a high potential to absorb anthropogenic CO(2) ( C ant). However, most data-based and model estimates indicate low C(ant) inventories south of 50 degrees S. In order to investigate this paradox, the distribution of C(ant) is estimated between South Africa and Antarctica ( World Ocean Circulation Experiment ( WOCE) line I6) based on a back-calculation technique previously used in the North Atlantic ( Kortzinger et al., 1998) and adapted here for application in the Southern Ocean. At midlatitudes (30 degrees-50 degrees S), formation and spreading of mode and intermediate waters results in a deep penetration of C(ant) ( down to 2000 m). South of 50...

Antibiotic prophylaxis in orthopedic surgeries: the results of an implemented protocol
Provedor de dados: 55
Autores: Queiroz,Raquel; Grinbaum,Renato S.; Galvão,Luciana L.; Tavares,Fernando G.; Bergsten-Mendes,Gun.
Though the basic principles of antibiotic prophylaxis have been well established, there is still considerable incorrect usage, including how much is prescribed and especially in the duration of treatment, which is generally superior to what is indicated. The adequate use of these drugs contributes towards decreasing the time of internment of the patient, prevents surgical site infection (SSI), decreasing the development of resistant microorganisms, and towards reduced costs for the hospital pharmacy. A protocol for the use of antibiotic prophylaxis in the Orthopedics and Traumatology Service of the Hospital do Servidor Público Estadual de São Paulo was developed. The objectives of the study were to promote rational antibiotic surgical prophylaxis, through...

Antifungal activity of phenolic compounds extracted from dried olive pomace
Provedor de dados: 21
Autores: Winkelhausen, Eleonora; Pospiech, Robert; Laufenberg, Günther.
The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0,1 and 0,2 %(w/v) and tested for their antifungal activity against the three fungi. In addition, the fungi were cultivated in a medium containing a commercial fungicide in the concentration of 0,2 % (w/v). Both of the phenolic concentrations inhibited the growth of all three fungi with the higher being more effective. It resulted in a four-fold reduction of the mycelial growth rate of A. solani and F. culmorum. The present...

Carpotroche brasiliensis is a native Brazilian tree belonging to the Oncobeae tribe of Flacourtiaceae. The oil extracted from its seeds contains as major constituents the same cyclopentenyl fatty acids hydnocarpic (40.5%), chaulmoogric (14.0%) and gorlic (16.1%) acids found in the better known chaulmoogra oil prepared from the seeds of various species of Hydnocarpus (Flacourtiaceae). These acids are known to be related to the pharmacological activities of these plants and to their use as anti-leprotic agents. Although C. brasiliensis oil has been used in the treatment of leprosy, a disease that elicits inflammatory responses, the anti-inflammatory and analgesic activities of the oil and its constituents have never been characterized.

Autores: Costa,Paulo Henrique Alves da; Neto,André Dias de Azevedo; Bezerra,Marlos Alves; Prisco,José Tarquinio; Gomes-Filho,Enéas.
Two forage sorghum genotypes were studied: CSF18 (salt-sensitive) and CSF20 (salt-tolerant). Shoot growth reduction as a result of salt stress was stronger in the salt sensitive genotype compared to the salt tolerant one. When the two genotypes were subjected to salt stress (75 mM NaCl) no significant change in lipid peroxidation was observed. However, salt stress induced increases in superoxide dismutase and catalase activities in both genotypes. These salt-induced increases were higher in the salt-tolerant genotype. Peroxidase activity was differentially affected by salt stress in the two genotypes. The activities of these peroxidases were decreased by salt stress in the salt-sensitive genotype and increased in the salt-tolerant genotype. In addition,...

Ants and their effects on an insect herbivore community associated with the inflorescences of Byrsonima crassifolia (Linnaeus) H.B.K. (Malpighiaceae)
Provedor de dados: 92
Autores: Fernandes,G. Wilson; Fagundes,Marcílio; Greco,Magda K. Barcelos; Barbeitos,Marcos Soares; Santos,Jean Carlos.
The effects of ants on the insect community on inflorescences of Byrsonima crassifolia (Malpighiaceae) were tested in an ant exclusion experiment in a cerrado vegetation in southeastern Brazil. Forty-four species of insects (23 families) and nine species of ants (6 genera and 3 subfamilies) were found on the inflorescences of B. crassifolia. The exclusion of ants, primarily Camponotus sericeiventris and Camponotus spp., reduced the treehopper population to 20% of the original abundance. Ant exclusion and time influenced the abundance of chewing (Exclusion, P&lt;0.001; Time, P&lt;0.002), and sucking insects (Exclusion, P&lt;0.02; Time, P&lt;0.01). Twice as many chewing and sucking insects were found on ant-excluded inflorescences as compared to control...

Apfeltrester im Schweinefutter reduziert die durch das Mykotoxin Deoxynivalenol verursachte Wachtumsreduktion
Provedor de dados: 21
Autores: Gutzwiller, Andreas; Stoll, Peter.
Fusarium head blight and the contamination of cereals with the Fusarium toxins deoxynivalenol (DON) and zearalenone is more prevalent when fields are not tilled in order to conserve the soil structure. DON impairs the feed intake and the growth rate of young pigs, whereas both, DON and zearalenone affect the fertility of sows. In two feeding trials using a total of 220 weaner pigs the hypothesis was tested that apple pomace alleviates the negative effects of Fusarium toxins. The two experiments had a 2 x 2 factorial design: Fusarium contaminated and uncontaminated wheat, and 8 % apple pomace and no pomace in the diet. In both trials, the animals receiving the mycotoxin contaminated diets without pomace gained less weight than the pigs receiving either...

APOA1/C3/A4 gene cluster variability and lipid levels in Brazilian children
Provedor de dados: 56
Autores: França,E. de; Alves,J.G.B.; Hutz,M.H.
Genetic studies have suggested that polymorphisms of genes coding for apolipoproteins are significant determinants of serum lipoprotein and lipid levels in adults. However, only a few studies have investigated the association of these polymorphisms in children. Therefore, in the present investigation we studied the distribution of APOA1 -75 G&gt;A, +83 C&gt;T, APOC3 -482 C&gt;T, -455 T&gt;C and 3238 C&gt;G, and APOA4 Q360H and T347S polymorphisms and their influence on plasma lipoprotein levels in children from a Brazilian northeastern admixed population. The seven polymorphic sites were genotyped in 414 children aged 5 to 15 years (mean 8.9 ± 2.9). The genotypes of the seven polymorphic sites were assessed by PCR-RFLP methods. The frequencies of the less...

Apoptotic mimicry: an altruistic behavior in host/Leishmania interplay

Autores: Wanderley,J.L.M.; Benjamin,A.; Real,F.; Bonomo,A.; Moreira,M.E.C.; Barcinski,M.A.
Apoptosis is the most common phenotype observed when cells die through programmed cell death. The morphologic and biochemical changes that characterize apoptotic cells depend on the activation of a diverse set of genes. Apoptosis is essential for multicellular organisms since their development and homeostasis are dependent on extensive cell renewal. In fact, there is strong evidence for the correlation between the emergence of multicellular organisms and apoptosis during evolution. On the other hand, no obvious advantages can be envisaged for unicellular organisms to carry the complex machinery required for programmed cell death. However, accumulating evidence shows that free-living and parasitic protozoa as well as yeasts display apoptotic markers. This...

A broad-range bacterial PCR target to conserved regions of the 23S rDNA was applied to 306 blood culture samples from 295 infants (up to one year of age) admitted to a neonatal intensive care unit. Classic blood culture results were compared to DNA sequencing analysis of the PCR amplification products. Culture results were in agreement to DNA sequencing in 90.5% (277) of 306 samples tested, including 263 PCR and culture negative samples and 29 culture and PCR positive samples. The sensitivity of the PCR method combined with sequencing was 88%, and the specificity was 96.3%, with positive and negative predictive values of 74.3 e 98.5%, respectively. The PCR-based approach directly applied to blood culture samples, correlated well with blood culture results...

Application of genetically modified mosquitoes in national vector control programmes: thoughts on integrated control
Provedor de dados: 26
Autores: Mnzava, A.; Curtis, C.F.; Manga, L.; Touré, Y.T.
Advances in transgenic technology have allowed the development of genetically transformed insects that have reduced ability to support the development of disease pathogens. The integration of this new method within national vector control programmes is indeed the biggest challenge, notwithstanding the current weak health systems in most disease-endemic countries (DECs) to efficiently apply vector control interventions. Moreover, where integration is considered, it is essential that reliable data are available on the multiple effects of the interventions. This should be done in parallel to the general strengthening of both human, technical, financial and physical resources at all levels of the national health system

Application of geographic information systems to the study of the ecology of mosquitoes and mosquito-borne diseases
Provedor de dados: 26
Autores: Gimnig, J.E.; Hightower, A.W.; Hawley, W.A.
Geographic information systems (GIS) are powerful computer mapping and analysis systems for studying spatial patterns and processes; they are applicable to numerous disciplines, including the study of mosquito ecology. The distribution of mosquitoes is largely dependent upon the spatial distribution of their larval breeding sites, their flight range and the spatial distribution of their preferred hosts. These are all heterogeneous in space and time and GIS therefore has many potential applications to the study of mosquitoes and the diseases they transmit. GIS may be used to map and analyse the spatial distribution of mosquitoes and to assess the ecological factors that contribute to observed distributions. A detailed understanding of what drives...

Application of Stochastic Dynamic Programming (SDP) for the optimal allocation of irrigation water under capacity sharing arrangements
Provedor de dados: 31
Autores: Gakpo,   E.F.Y.; Tsephe,   J.; Nwonwu,   F.; Viljoen,   Machiel F.
This study attempts to arrive at an optimal allocation of irrigation water using capacity sharing (CS) as an institutional arrangement, and stochastic dynamic programming (SDP) as an optimisation model. It determines the value of an additional unit of water under a crop enterprise mix of lucerne-maize-wheat (LMW). SDP is an improvement on linear programming (LP) under stochastic conditions. The SIM-DY-SIM Model was used to simulate optimal returns, decision and policy variables under varying conditions of capacity share. LP results show that wheat has the highest MVP of R0.39/m3, with maize exhibiting the lowest value of R0.09/m3. The MVPs generated with SDP range between R0.06/m3 and R0.35/m3 on the whole farm basis, with revenue to the farmer increasing...

The objective of this work was to evaluate the inter treatment discrimination according to feed conversion efficiency in several animal performance experiments. The variables investigated were: feed conversion ratio (FCR = intake: production ratio), feed efficiency index (FEI = production: intake ratio) and bio-nutritional index (BNI). The BNI was constructed from the first canonical variable obtained based on the multivariate analysis of variance of the intake and animal production (weight gain or milk production) variables. The results indicated that FCR and FEI reciprocated each other at experimental plot level but did not reciprocate at animal group or treatment level. This fact implicates distortions on the descriptive levels of probability of type I...

Applied aspects of pineapple flowering
Provedor de dados: 53
Autores: Cunha,Getúlio Augusto Pinto da.
Flowering is an amazing, integrated and complex process of multifatorial control, which due to its great importance for agriculture has been extensively studied worldwide. Pineapple is one of the main crops on which many research works about this subject have been carried out, and it was the first one to have artificially induced flowering. However, even with all those studies, pineapple flowering is not yet characterized in many aspects. The main point for the comprehension of the physiologic aspects of flowering initiation is the identification of the factors involved in the differentiation of the apical meristem into floral primordium, as well as how these factors exert their action. This work aimed to describe the flowering process of pineapple plants,...

Applied research as interplay between farm and group level: What attracts laying hens to the hen run?
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
On farm research is well established in organic farming. The holistic approach considers the complexity of a farm and the findings will be implemented immediately. As the experiments are often performed on single farms the results are difficult to transfer to others. Controlled experiments on group level with representative samples investigate single factors and lead to reliable and well-founded results. However, they are often far away from implementation. Applied research requires interplay of on farm research and controlled experiments. A series of ethological research work should show how this interplay may take place.

Applying Retrospective Demographic Models to Assess Sustainable Use: the Maya Management of Xa&amp;#8217;an Palms
Provedor de dados: 7
Xa&amp;#8217;an palm (Sabal yapa) has been used to thatch traditional Maya houses for over 3000 years. In the Yucatan Peninsula, this palm has been introduced to pasturelands, maize fields (milpas), and homegardens. These and other traditional management systems are usually believed to be sustainable, but there is as yet little evidence to support this hypothesis. Demographic models have been used for this purpose, mainly focusing on population growth rate (&amp;#955;). So far, retrospective analysis has not been applied, even though it examines how changes in the  the life cycle of a species, caused by different management regimes, affect its &amp;#955;. In this study, we assess whether ecologically sustainable use of xa&amp;#8217;an occurs in...

Many very different approaches to landscape patterns are used all over the world in landscape ecology, landscape planning and management. Intensive development of geographical information systems in the last decade has meant increasing interest in analysing landscape changes. GIS has enabled quantification of the spatial changes in large areas, and the provision of much more representative results. However, implementation of the results into landscape planning and management is still not satisfactory. Proposals for analysing changes in land use and the attributes of landscape patterns have been developed and tested in four study areas representing different landscape types. Changes in landscape patterns based on land use are monitored between 1845 and...

Applying the Miceli Model to Explain Cooperation in Municipal Solid Waste Management
Provedor de dados: 31
Autores: Tiller,   Kelly; Jakus,   Paul M.
As traditional methods of municipal solid waste management (MSWM) become increasingly expensive due to increased regulation, many local governments are considering cooperation as a waste management strategy. A theoretical model is used to specify a partial observability probability model to analyze the decision Tennessee counties made to form either a single-county solid waste region or a multi-county region. We find that, while economies of scale may be a factor in the consolidation decision, similarities and differences between counties in current individual provision levels of solid waste services, ability to pay for services, and expectations for future solid waste service demands are statistically more important.

Continental margins play a crucial role in biogeochemical fluxes between the continents and the open ocean. They are also highly sensitive to human perturbations. Primary production is highly dependent on the complex dynamics of these coastal zones, and on the river supply in nutrients, as well as in Suspended Particulate Matter (SPM) which limit light availability. The quantification of the production is a prerequisite in many applications, from the understanding of the role of the coastal ocean in climate change, to eutrophication and fisheries resources issues within the frame of the integrated management of the coastal zone.  Coupled physical-biogeochemical models are useful in studying and monitoring primary production. Because of the numerous complex...

Although the European organic agriculture movement was founded by Rudolf Steiner and Hans Mueller in the years between 1924 and 1940, it was not until the 1980s that pest management researchers began to develop strategies to control pests in organic systems. Today, insect pest management in organic agriculture involves the adoption of scientificallybased and ecologically sound strategies as specified by international and national organic production standards. These include a ban on synthetic insecticides and, more recently, on genetically modified organisms (GMOs). The first phase of an insect pest management program for organic systems is the adoption of cultural practices including diverse crop rotation, enhancement of soil quality by incorporation of...

O aproveitamento como adubo orgânico foi comparado com o de esterco, em plantio de milho, irrigado, a campo. Foram comparadas as doses de 20 e 40 t ha-1 de matéria seca com testemunha, sem adubo. Paralelamente, foi acompanhada a decomposição do material incorporado ao solo. A massa de E. densa decompôs-se rapidamente, restando menos de um terço após um mês e menos de 1% após dois meses. As adubações com E. densa e esterco incorporaram grande quantidade de nutrientes ao solo e resultaram em produção de grãos de milho (3,5 a 8,5 t ha-1) e palha (4,3 a 8,8 t ha-1) muito maior que a da testemunha (0,3 e 1,2 t ha-1). Em média, as...

Aproveitamento de bagaço de maçã para a produção de álcool e obtenção de fibras alimentares
Provedor de dados: 64
Autores: Paganini,Cícero; Nogueira,Alessandro; Silva,Nelci Chiquetto; Wosiacki,Gilvan.
A produção brasileira de maçã, cerca de 850 mil toneladas, supre o mercado interno para consumo in natura e o rigor do beneficiamento fez com que as "maçãs industriais" se tornassem expressivas, pois podem atingir 200.000 toneladas na safra 2005/2006. Além de sidra e vinagre, é produzido suco clarificado concentrado, o que abre as portas de exportação tanto para outros estados quanto para outros países. O bagaço residual também pode ser aproveitado. Com este trabalho, objetivou-se determinar os parâmetros da extração de açúcar para processos fermentativos e para produção de um resíduo sólido com elevados teores de fibras alimentares. Foram utilizadas maçãs das variedades Fuji, Gala e Golden delicious, as comerciais mais expressivas economicamente,...

Aquaculture and Fisheries Interactions: Implications for the Global Supply of Fish
Provedor de dados: 31
Autores: Arnason,   Ragnar.
Aquaculture, or more generally fish farming, and fisheries interact in several different ways.  First, many types of fish farming require fish products as inputs, mostly for feeding purposes.  Second, farmed fish and wild fish products compete in fish markets with consequences for both the industry and, of course, consumers.  Third, fish farming generates various types of polluting agents that may affect wild fish stocks and their habitat.  Several other interactions exist.  This paper is primarily concerned with the implications of the first of these interactions, namely the input relationships, for the overall supply of fish products in the future.  To the extent that the fish farming industry demands wild fish products such as fish meal, fish oil, etc....

ARBUSCULAR MYCORRHIZA OF WINTER WHEAT UNDER DIFFERENT DURATION OF ORGANIC FARMING
Provedor de dados: 21
Autores: Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard.
The effect of continuous organic farming (OF) on the arbuscular mycorrhizal fungi (AMF) of winter wheat (Triticum aestivum) was investigated in a greenhouse pot trial. Representative soil samples were taken from 5 farms in the “Weinviertel” region, northeast of Vienna, Austria. On each farm three sites with a different duration of OF were selected for soil sampling; wheat was used as test plant. The mycorrhizal colonization (MC), root length density (RD) and the mycorrhizal colonized root length density (MD) were evaluated for the wheat roots. The majority of the wheat plants indicated an increasing MC and MD with increasing duration of OF. Based on our results we assume that a conversion period from conventional to OF of approximately 15 years is needed...

Arbuscular mycorrhizal fungi and the occurrence of flavonoids in roots of passion fruit seedlings
Provedor de dados: 63
Autores: Soares,Ana Cristina Fermino; Martins,Marco Antônio; Mathias,Lêda; Freitas,Marta Simone Mendonça.
Composition and the role of root flavonoids in the regulation of mycorrhizal symbiosis are still poorly understood. Several flavonoids stimulate spore germination, mycelia growth and root colonization by arbuscular mycorrhizal fungi (AMF), and both root colonization and flavonoid composition are affected by plant nutritional status. Effects of AMF on the occurrence and content of aromatic secondary metabolites in the roots of passion fruit seedlings grown under two levels of phosphorus (P) fertilization (10 and 50 mg kg-1 of phosphorus) was studied. Seedlings were inoculated with Glomus clarum and a population of native fungi from a passion fruit plantation. Methanolic extracts of passion fruit seedlings roots were analyzed by high performance liquid...

Archaeocidaris M’Coy (Echinoidea) from the Carboniferous of Egypt
Provedor de dados: 16
Autores: Lewis, D.N.; Donovan, S.K.
Collections in museums usually have boxes of specimens which remain ‘undiscovered’ and yet which may be of importance or interest. The recent rediscovery of specimens of Archaeocidaris in the Nationaal Natuurhistorisch Museum, Leiden, from the Carboniferous of Egypt illustrates this point. These specimens were collected in 1938 by Dr. H.M.E. Schürmann (1891-1979), who had been a student of Professor J. Wanner (1878-1956), the noted expert on fossil echinoderms. The Egyptian Archaeocidaris plates include interambulacrals and radioles. These are closest to Archaeocidaris rossica (von Buch) from the Moscow area of Russia, although there are sufficient differences in radiole morphology to suggest that they are not necessarily conspecific.

Are Agricultural Measures for Groundwater Protection Beneficial When Compared to Purification of Polluted Groundwater?
Provedor de dados: 31
Autores: Hasler,   Berit; Lundhede,   Thomas.
The groundwater resource, the drinking water areas and the surface water quality can be protected by measures, e.g. by reductions of pesticide and nutrient applications, conversion of arable land to grasslands or forests etc. The objective of the paper is to estimate the benefits of groundwater protection by the valuation method choice experiments. This method allows for separate estimation and comparison of the different attributes connected to groundwater protection i.e. the effects on drinking water and surface water quality as compared to the benefits from cleaning and treatment of polluted drinking water to make it suitable for drinking water consumption. The results indicate that the benefits are significant, and that the willingness to pay for...

Are Agricultural Values a Reliable Guide in Determining Landowners’ Decisions to Create Carbon Forest Sinks?
Provedor de dados: 31
Autores: Shaikh,   Sabina L.; Sun,   Lili; van Kooten,   G. Cornelis.
This research examines the effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes, and potential costs of sequestering carbon through afforestation in western Canada. Using data from a survey of landowners, a discrete choice random utility model is used to determine the probability of landowners’ participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative benefits to landowners from planting trees, benefits not captured by foregone returns from agricultural activities on marginal land. Estimates of WTA are less than foregone returns, but even so average costs of creating carbon credits...

This paper examines the hypothesis that social capital at the individual level affects environmentally friendly practices. Social capital represents the social connectedness of the individual. An individual with higher social capital is more likely to have better exposure and access to information about the importance of environmentally friendly practices. We study sustainable agricultural practices among Georgia farmers and examine whether their social capital levels have any effect on, (1) their adoption of sustainable agricultural practices, and (2) the extent to which they engage in these practices. Using the Georgia Social Capital Survey our measure of social capital is associational activities. We address a number of econometric issues: potential...

Are fungivorous Scarabaeidae less specialist?
Provedor de dados: 67
Autores: Falqueto,Silvia A; Vaz-De-Mello,Fernando Z; Schoereder,José H.
In a tropical forest patch of Southeastern Brazil, adult Scarabaeidae beetles were used to test the hypothesis that fungivorous guilds have a higher proportion of generalist species than either frugivorous, necrophagous or coprophagous ones. No significant differences were found between guilds in relation to either the proportion of generalists or niche breadths of the component species. Only two fungivorous specialist species were sampled. These results indicate that sporocarps eaten by Scarabaeidae are not as rare as literature suggests. Fungi may help maintain high species diversity of Scarabaeidae in tropical forests.

Are high-lysine cereal crops still a challenge?
Provedor de dados: 56
Autores: Ferreira,R.R.; Varisi,V.A.; Meinhardt,L.W.; Lea,P.J.; Azevedo,R.A.
The essential amino acids lysine and threonine are synthesized in higher plants via a pathway starting with aspartate that also leads to the formation of methionine and isoleucine. Lysine is one of most limiting amino acids in plants consumed by humans and livestock. Recent genetic, molecular, and biochemical evidence suggests that lysine synthesis and catabolism are regulated by complex mechanisms. Early kinetic studies utilizing mutants and transgenic plants that over-accumulate lysine have indicated that the major step for the regulation of lysine biosynthesis is at the enzyme dihydrodipicolinate synthase. Despite this tight regulation, recent strong evidence indicates that lysine catabolism is also subject to control, particularly in cereal seeds. The...

Are Household Production Decisions Cooperative? Evidence on Pastoral Migration and Milk Sales from Northern Kenya
Provedor de dados: 31
Autores: Doss,   Cheryl R.; McPeak,   John G.
Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives’ ability to market milk.

Are Japanese bureaucrats politically stronger than farmers?: The political economy of Japan's rice set-aside program
Provedor de dados: 31
Autores: Arahata,   Katsumi.
The purpose of this paper is to examine the political process of bureaucrats' seemingly discretionary allocations among prefectures in Japan's rice set-aside program. Some hypotheses and a model are proposed and then these are empirically tested. Two major findings of this study are as follows:     Firstly, it is suggested that the bureaucrats' discretionary allocation tends to be revised in response to political pressure. Consequently, allocations among prefectures tend to be inversely proportionate to the degree of political pressures. Moreover, such pressures can be explained by the expected income from rice-production and the share of part-time farmers, who are the majority in Japanese rural society and politically powerful.     Secondly, among various...

Are poor, remote areas left behind in agricultural development: the case of Tanzania
Provedor de dados: 31
Autores: Minot,   Nicholas.
In Tanzania, as in many other developing countries, the conventional wisdom is that economic reforms may have stimulated economic growth, but that the benefits of this growth have been uneven, favoring urban households and farmers with good market access. This idea, although quite plausible, has rarely been tested empirically. In this paper, we develop a new approach to measuring trends in poverty and apply it to Tanzania in order to explore the distributional aspects of economic growth and the relationship between rural poverty and market access. We find that, between 1991 and 2003, a period of extensive economic reforms, the overall rate of poverty fell about 9 percentage points. The degree of poverty reduction was similar between rural and urban areas,...

Are standards and regulations of organic farming moving away from small farmers' knowledge?
Provedor de dados: 21
Autores: Vogl, Christian R.; Kilcher, Lukas; Schmidt, Hanspeter.
Organic farming is a promising agricultural method with positive effects on the human ecological and social environment. Governments have taken over a major role in defining organic farming by creating legal standards. Many countries all over the world have established a certification and accreditation system in order to protect the justified expectations of consumers with regard to processing and controlling the product quality of organic goods and to protecting producers from fraudulent trade practices. As they are relevant to international trade, these standards do not only influence the organic farming movement on the national level but also have a converse impact across national borders. Organic farming was established in a bottom-up process as...

ARE THE EFFECTS OF THE MACROECONOMY AND SOCIAL POLICIES ON POVERTY DIFFERENT IN RURAL AMERICA?
Provedor de dados: 31
Autores: Gundersen,   Craig.
The macroeconomy and social policies can have substantial influences on poverty in the United States. In this paper, I investigate whether these influences differ across metro and nonmetro areas. To do so, using a 16-year panel of state-level data, I estimate state and year fixed effects models separately for metro and nonmetro areas to see if the effects of the macroeconomy and social policies differ between these two areas. These models are estimated using two measures– the poverty rate and the squared poverty gap – and by family type. I find that cyclical forces have a much stronger effect on the poverty rate in nonmetro areas in comparison to metro areas but the effects are similar for the squared poverty gap; wage growth has a pronounced effect on...

Are there customary rights to plants? An inquiry among the Baganda (Uganda), with special attention to gender
Provedor de dados: 31
Autores: Howard,   Patricia L.; Nabanoga,   Gorettie.
Debates around Common Property Resources and Intellectual Property Rights fail to consider traditional and indigenous rights regimes that regulate plant resource exploitation, establish bundles of powers and obligations for heterogeneous groups of users, and create differential entitlements to benefits that are related to social structures. Such rights regimes are important to maintaining biodiversity and to human welfare; failing to recognize them presents dangers. The case study investigates the gendered nature of informal rights to selected tree and plant species that are distinct from, but related to, customary rights to land and trees, and are embedded in cosmology and social norms.

Áreas de acción en un ensamble de roedores del Desierto del Monte (Mendoza, Argentina)
Provedor de dados: 81
Autores: Corbalán,Valeria E.; Ojeda,Ricardo A.
In the central portion of the Monte desert four small rodent species coexist: Graomys griseoflavus, Akodon molinae, Eligmodontia typus, and Calomys musculinus . Using the Convex Polygon Method, we assessed the home range of these species at different habitats and made comparisons among species, and between sexes and different seasons of the year. We found that home range did not differ among species, but there is a tendency to increase range size as the species corporal size increases. Overlapping of home range was different at different seasons of the year, probably due to different population densities, but home range size was constant along the year. Habitat type and sex affect home range only for G. griseoflavus and A. molinae, respectively.

Arkansas Landlord Selection of Land-Leasing Contract Type and Terms
Provedor de dados: 31
Autores: Rainey,   Ronald L.; Dixon,   Bruce L.; Ahrendsen,   Bruce L.; Parsch,   Lucas D.; Bierlen,   Ralph W.
Land leasing is a major source of the land input to production agriculture. Responses from a survey of landlords leasing crop land in Arkansas are analyzed to better understand those factors motivating landlords in the type of lease they select and the terms of those leases. Probit models are estimated to determine the relative importance of variables representing credit constraint, agency problem, and risk aversion factors. Regression models then estimate the impact of site, landlord, and tenant characteristics on contract terms – the percentage of crop and cost sharing arrangements between landlord and tenant. Probit results suggest credit constraint factors influence lease-type selection. Risk aversion, managerial ability, and social capital factors are...

Armazenamento refrigerado da uva de mesa 'Romana' (A1105) cultivada sob cobertura plástica
Provedor de dados: 70
Autores: Lulu,Jorge; Castro,Josalba V.; Pedro Júnior,Mário J.
A videira é uma das principais fruteiras cultivadas em todo o mundo e atualmente a preferência por uvas do tipo "sem sementes" ou "apirênicas" vem aumentando gradativamente no mercado interno brasileiro. A cultivar 'Romana' (A1105) tem mostrado grande potencial como nova alternativa de uva de mesa apirênica na região de Jundiaí - SP. No entanto, a qualidade dos cachos tem sido afetada pela ocorrência de chuvas na época da colheita, propiciando a incidência de rachaduras nas bagas ("cracking") e podridões. Visando a solucionar essa dificuldade, foram conduzidos experimentos de campo em vinhedo cultivado em cortina dupla e sob cobertura plástica. Após a colheita, foram coletadas oito amostras com seis cachos cada, que foram armazenadas a 3 ºC e submetidas a...

ARPA Subsidies, Unit Choice, and Reform of the U.S. Crop Insurance Program
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Hart,   Chad E.
The Agricultural Risk Protection Act (ARPA) has largely met its objectives of inducing farmers to increase their use of the crop insurance program. Both insured acreage and coverage levels have increased dramatically in response to ARPA's large increase in premium subsidies. An unintended consequence of the larger subsidies is a dramatic increase in the incentive for farmers to insure their crops under optional units, that is, insurance at the field level rather than at the farm or crop level. The expected rate of return to farmers who choose to invest additional premium dollars to move to optional unit coverage ranges from a low of 61 percent at the 85 percent coverage level to 144 percent at the 65 percent coverage level. This explains why the majority...

Palavras-chave: En pequeños países en desarrollo como Uruguay; Los beneficios económicos potenciales que se obtendrían por la adopción de nuevas tecnologías agrícolas basadas en biotecnología están limitados por una base productiva reducida. En este trabajo se evalúa ex - ante el impacto económico de una variedad de arroz transgénico resistente a herbicidas donde el poder de mercado de la multinacional propietaria de la variedad afecta las tasas de adopción a través del margen monopólico en el precio de la semilla. Se emplean métodos de simulación estocástica para estudiar la variación de los resultados a cambios en los parámetros tecnológicos y en las tasas de adopción. La media del excedente económico de los productores es de US$1; 82 millones; Mientras que la ganancia monopólica es de US$0; 55 millones. Estos beneficios económicos relativamente escasos sugieren que; Sin estrategias de política pública que incrementen los beneficios potenciales y reduzcan los costos de investigación; Las multinacionales no invertirían recursos significativos en el desarrollo de una variedad transgénica adaptada a las condiciones locales.

Artenreiches Rauhfutter als Alleinfutter und Fettsäurenmuster der Milch

Autores: Leiber, Florian; Kreuzer, Michael; Scheeder, Martin R.L.; Wettstein, Hans-Ruedi.
In two experiments it was investigated which factors to what extent determine the fatty acid composition milk when cows are grazing high alpine pastures. The influences of altitude per se, of alpine forage quality, of concentrate-free diet type and of the overall grazing effect were separated by the experimental design. The most important factor which significantly elevated the concentrations of CLA, α-linolenic acid (ALA) and n-3 PUFA in milk fat was found to be the alpine diet type, i.e. the feeding of roughage-only (as well hay as pasture of as well lowland as alpine origin) with omission of concentrates and maize. Additionally a clear positive effect of the forage quality of alpine pastures on ALA concentration in milk fat was found. The latter effect...

Autores: Streit,Nivia Maria; Canterle,Liana Pedrolo; Canto,Marta Weber do; Hecktheuer,Luísa Helena Hychecki.
As clorofilas são pigmentos verdes, comuns em todas as células fotossintéticas. Por sua estrutura química ser instável, são facilmente degradadas, resultando em produtos de decomposição que modificam a percepção e qualidade dos alimentos. Esta revisão trata dos vários fatores que interferem na degradação das clorofilas, como a luz, radiação, calor, ácidos, oxigênio, alteração enzimática e interação com outros pigmentos. Também, outro aspecto a ser abordado é a utilização das clorofilas como corantes, através da formação de complexos que tornam esses pigmentos mais estáveis à decomposição.

Autores: Mielitz Netto, Carlos Guilherme Adalberto.
A conclusão da Rodada Uruguai do GATT em 1994 não trouxe o fim das disputas comerciais no mercado agrícola mundial, como se propagava. As formas de intervenção das políticas agrícolas norte-americana e européia passaram a atuar de forma mais indireta, mas ainda guardando um elevado grau de proteção às suas respectivas agriculturas e provocando expressivas distorções nos mercados internacionais. O discurso liberalizante que se fazia presente desde então muda crescentemente de direção após 2001, quando ambas políticas passam por revisão ou novas proposições. A contínua troca de acusações entre os dois maiores contendores sobre a quem caberia a maior responsabilidade nas distorções no mercado, a resistência à revisão das posições, o conturbado cenário...

Existem muitas preocupações ecológicas do impacto que a construção de grandes lagos na Amazônia podem provocar, principalmente relacionadas ao microclima. Este estudo visa aumentar o conhecimento científico sobre a distribuição de chuvas antes e depois da formação do lago artificial da UHE Tucuruí-PA. Foram utilizados dados diários de precipitação dos períodos de 1972 a 1983 (pré-enchimento) e de 1984 a 1996 (pós-enchimento) para as cidades de Tucuruí e Marabá-PA. Comparando-se os totais mensais (pré e pós-enchimento), não se observam diferenças estatisticamente significantes (foram aplicados os testes de Fisher e Man-Whitney). Analisando-se a ocorrência de dias com precipitação superior a 5 e 25 mm.dia-1, também não se observam diferenças estatisticamente...

Ascidians at Currais islands, Paraná, Brazil: taxonomy and distribution
Provedor de dados: 49
Autores: Rocha,Rosana Moreira da; Faria,Suzana Barros de.
The Currais Islands is a group of a few small rocky islands in the state of Paraná, in southern Brazil, which provides an interesting location for the study of ascidians. Subtidal diversity is very high and the islands have recently been proposed as a Conservation Unit. A field study was established on the largest island to understand ascidian distributions on spatial and temporal scales. Transects, sampled three times during 2002 and 2003, were established on northern and southern locations of the island as well as at three depths. Twenty species were recorded; the most common were Didemnum rodriguesi, Didemnum speciosum and Didemnum granulatum. Three species are possibly new and will be described elsewhere. An additional nine are new records for the...

De las distintas formas de la asimetría bilateral, la asimetría direccional (AD) ha recibido considerablemente menos atención en la literatura que la asimetría fluctuante (AF). Si bien existen buenos ejemplos de AD conspicua en algunos grupos de moluscos (e.g., Ostreidae y Pectinidae), para otros como los mitílidos la AD no ha sido reportada. En matrices del chorito Perumytilus purpuratus de tres localidades del intermareal rocoso de Chile norte y central, comparando individuos de los estratos superior e inferior, y usando dos índices de forma de la valva, reportamos evidencia de AD en relación con la forma de las valvas, tendiendo la derecha a ser consistentemente más elongada que la valva izquierda.

Provedor de dados: 20
Autores: Schejter, L.
The different aspects of the benthic assemblages at the Patagonian scallop beds in the Argentine Sea (SW Atlantic) were studied. The Patagonian scallop (Zygochlamys patagonica) is a commercial species distributed in the Magellanic Biogeographic Province, and has been commercially exploited since 1996. Temporal and spatial studies were performed in the community composition between 39°50'S and 36°15'S, and between 1998 and 2003, concluding that the species association was persistent after more than 7 years of trawling activities. Species composition in an exclusion area (closed to scallop fishing) did not differ from surrounding fished areas during the studied period, showing only a higher scallop biomass. ABC curves showed a pattern coincident with a non...

O guaco (Mikania glomerata Sprengel) é espécie de uso medicinal conhecida pela atividade broncodilatadora. Muitos estudos têm evidenciado mudanças nas características anatômicas e fisiológicas de plantas medicinais sob influência de condições de radiação. Neste trabalho analisou-se a influência de fotoperíodos (8; 12; 16 e 20 h) na anatomia foliar, nos teores de clorofila e condutância estomática em três regiões da planta. Após 90 dias de tratamento, plantas adultas e com diferentes tamanhos influenciados pelos fotoperíodos foram submetidas às avaliações anatômicas e fisiológicas. Os teores de clorofila foram maiores nos fotoperíodos de 8 e 12 h nas regiões superior e mediana da planta e menores no fotoperíodo de 8 h na região basal. A condutância e...

Aspectos atuais da distribuição geográfica de Anopheles (Kerteszia) cruzii Dyar &amp;amp; Knab, 1908 no estado do Espírito Santo, Brasil
Provedor de dados: 71
Autores: Rezende,Helder Ricas; Cerutti Junior,Crispim; Santos,Claudiney Biral dos.
Anopheles cruzii was registered in Espírito Santo state both in 1957 and 1968. Our study provides additional evidence of its presence, including municipalities that were non mentioned before. Anopheles captures undertaken between 1998 and 2003 pointed out a distribution restricted to the forested outskirts of the mountains in the highland area of the state. Its epidemiological role is suggested by the simultaneous presence of malaria cases in the same municipalities.

ABSTRACT: Insects commonly well-known as white grubs are the larval phase of beetles that belong to the Melolonthidae (Coleoptera). This family contains an expressive number of insect species that have different bioecological functions in the agroecosystems in the adult and immature phases. In four of five trophic levels, they are primary and secondary consumers, secondary producers and decomposers. In Brazil there are registred about 1008 species of Melolonthidae whose larvae live in the soil. Some of them are considered important pests; normally the larval phase feed the crop roots causing damages. The symptoms occur in patches with smaller plants, yellow leaves, and drastic reduction in the plant population. The occurence of those insects in the...

Aspectos da fenologia e ecologia de Hedychium coronarium (Zingiberaceae) na estação ecológica do Tripuí, Ouro Preto-MG
Provedor de dados: 87
Autores: Santos,S.B.; Pedralli,G.; Meyer,S.T.
Hedychium coronarium é uma macrófita aquática considerada exótica e invasora fora da região do Himalaia, seu centro dispersor. Introduzida nas Américas, ocorre em diversas regiões do Brasil, inclusive na Estação Ecológica do Tripuí (EET), Ouro Preto-MG. As macrófitas invasoras ocasionam efeitos negativos sobre a biodiversidade regional e, portanto, requerem estudos sobre sua fenologia e ecologia como subsídio para medidas de controle e manejo. Aspectos relacionados a crescimento em altura, floração, frutificação e duração das hastes foram avaliados entre agosto de 2002 e julho de 2003 em diferentes áreas da EET. Áreas com sombreamento entre 60 e 80% apresentam maior crescimento em altura e melhor frutificação, merecendo, por isso, maior atenção para o...

Aspectos do controle da mosca-dos-chifres e manejo de resistência.
Provedor de dados: 14
Autores: BARROS, A. T. M. de.
A mosca-dos-chifres é uma praga relativamente recente na bovinocultura brasileira, introduzida na região Centro-Oeste há pouco mais de uma década. Desde então, seu controle tem sido dependente do uso de produtos inseticidas, o que tem sido realizado, de modo geral, de forma abusiva e indiscriminada em todo o país. Ao longo dos anos, o controle químico deste e de outros ectoparasitas tem levado à seleção de populações resistentes, reduzindo a eficácia dos produtos, mantendo perdas na produtividade e encarecendo os custos do manejo sanitário e, em última análise, da produção.

Aspectos Moleculares en la Formación de la Cara y del Paladar
Provedor de dados: 77
Autores: Montenegro,María Angélica; Rojas,Mariana.
En mamíferos, la adhesión y fusión de los procesos faciales y palatinos, son mecanismos esenciales en el desarrollo del paladar primario y secundario. La falla de cualquiera de estos procesos trae como consecuencia la formación de labio leporino o fisura palatina. En ambos casos, los procesos opuestos adhieren a través de desmosomas para formar una lámina epitelial media la cual desaparece por transformación epitelio-mesenquimática. La apoptosis ocurre sólo en las células del periderma. En el paladar secundario, estos procesos están regulados por TGFß-3, pero este factor no está presente en los procesos maxilares o nasales que forman el paladar primario, por lo cual en la formación del labio actuarían otros factores tales como Shh (sonic hedgehog) y BMP...

Aspects of the Definition and Classification of Farms
Provedor de dados: 31
Autores: Lund,   Philip J.
This paper examines what, precisely, is meant by a 'farm' and considers various attributes of farms relevant to an assessment of the structure of European agriculture. A measure of average farm size is proposed to cope with the uncertain count of the population of farms. The issue of tenure may also be complex, with some farms consisting of separate parcels of land, each with different tenure situations. Finally, although many European farmers are often described as being 'part-time', there are a number of different criteria on the basis of which farmers, and also farms, may be classified as being part-time.

Presprouting of seed tubers is a measure that is often recommended for organic potato growing. In on-farm field experiments the effect of presprouting was evaluated with respect to virus infection, yield and weed infestation. The effect of presprouting on yield was largely dependent on the year and on the late blight severity. Weeds were not affected significantly by presprouting. In most experiments virus incidence was higher in presprouted potatoes. Presprouting also had a suppressive effect on undesired regrowth after haulm destruction.

Aspergillus niveus Blochwitz 4128 URM isolated from sunflower rhizosphere demonstrated a new source of inulinase. The enzyme was produced in culture medium containing inulin as substrate in the concentrations: 10, 15 and 20g L-1. Maximum enzyme activity was obtained in medium containing 20g L-1 inulin. The enzyme was partially purified using ammonium sulphate precipitation, followed by ion charge (DE-32) and molecular exclusion (Sephadex) chromatography. The results showed the optimal pH and temperature of inulinase from crude extract were 4.0 and 4.8 and 45ºC, respectively. The enzyme was purified 34.65 fold with yield of 53.63%. A. niveus 4128URM can be used in the inulinase production with use in the food industries.

Autores: Loureiro,   Maria L.; Umberger,   Wendy J.
In this paper, we assess consumer willingness to pay for a mandatory country-of-origin labeling (COOL) program applied to beef ribeye steaks, chicken breasts, and pork chops, all labeled as “Certified U.S.” products. A consumer survey was mailed in spring and early summer 2003 to households in the continental United States.  Results indicate that consumers are in general very concerned about food safety issues, viewing U.S. meats as the safest among the selection of countries considered.  Nevertheless, consumer willingness to pay for Certified U.S. products is relatively small, although above the expected implementation costs associated with a mandatory labeling program.  This finding coincides with the fact that only 36% of the sample favored consumers...

Assessing Ecological Risks at the Landscape Scale: Opportunities and Technical Limitations
Provedor de dados: 7
Autores: Kapustka, Lawrence A; ecological planning and toxicology, inc.; Larry_Kapustka@golder.com.
There is a growing awareness that ecological risk assessments (ERAs) could be improved if they made better use of ecological information. In particular, landscape features that determine the quality of wildlife habitat can have a profound influence on the estimated exposure to stressors incurred by animals when they occupy a particular area. Various approaches to characterizing the quality of habitat for a given species have existed for some time. These approaches fall into three generalized categories: (1) entirely qualitative as in suitable or unsuitable, (2) semiquantitative as in formalized habitat suitability index models, or (3) highly quantitative site-specific characterization of population demographic data such as matrix population models or...

Assessing farmers' risk attitudes based on economic, social, personal, and environmental sources of risk: evidence from Sweden
Provedor de dados: 31
Autores: Lagerkvist,   Carl Johan.
This paper examines farmers'’ risk attitudes, obtained by responses to sources of risk, using an attitudinal scale approach. Economic, social, personal, and environmental sources of risk are considered in the measurement of risk attitudes. In addition, use of various types of expertise and information sources are included as risk management tools. Inferences are drawn from results of a survey mailed to a representative random sample of 500 farmers drawn from the population of medium to large farms (by acreage) in southern Sweden. Regarding the adequacy of the results it was found that a mail survey produces results similar to earlier results obtained by personal interview. Farmers'’ responses to the attitudinal scales showed levels of communal variation...

Though the two endpoints of the channel remain the manufacturer and grower, many more options are evolving for transferring products, services, and information through the channel.  Traditionally, the retail dealer was the pivot point in moving products, services, and information through the channel but as changes have occurred in the industry, and with technology, that role is evolving.   Some of the factors driving change in the distribution channel for crop inputs include: • Competition, as new intermediaries enter the marketplace (consultants, brokers, wholesalers, large growers);   • Consolidation, at all levels of the distribution...

Assessing Price Forecasting Models for Organic Commodities
Provedor de dados: 21
Autores: Gubanova, Tatiana; Escalante, Cesar; Lohr, Luanne; Park, Timothy.
This project develops price forecasting models to guide organic commodity marketing decisions.  Forecasting models for organic commodity prices at the farm level are specified and tested using a comprehensive national farm price series data set collected for organic commodities in the United States.  A framework for testing the predictive ability of competing models using conditional predictive ability is developed.  Forecast performance is evaluated using the root mean squared error (RMSE) and mean absolute error (MAE) for point forecast comparison along with tests for market timing ability of the forecasting model.

Assessing the effectiveness of sales promotion on organic products
Provedor de dados: 21
Autores: Hamm, Ulrich; Wild, Sandra.
This paper presents and comments on basis data for point of sale marketing on organic products. The research on promotions to date has been directed only towards conventional products. Therefore, the main issue of the study is to offer an overview of sales promotion instruments as well as evaluating different kinds of sales promotions and improving their effectiveness for organic products. The research addresses the optimal design of a series of promotions, which especially approach non-customers and occasional customers of organic products. This study is based on a quantitative empirical method which allows the comparison of sales promotion effectiveness for organic food in food retailing and specialised organic food retailing. Besides that, the study...

ASSESSING THE EFFECTS OF NAFTA ON CANADA/US AGRICULTURAL TRADE
Provedor de dados: 31
Autores: Deng,   Hugh; Nzuma,   Jonathan M.
While there seems to be an agreement that Canada-US Free Trade Agreement (CUSTA)/North American Free Trade Agreement (NAFTA) have benefited member countries, some analysts have argued that the agreements had little effect on the bilateral Canada/US agricultural trade as many other factors have contributed to the increased trade flows. Results from this study reveal that the aggregate bilateral agricultural trade flows have generally experienced a steady growth since the implementation of NAFTA with trade flows seemingly favoring Canada more than the US since 1992. At the industry level, the impacts of NAFTA on Canada/US agricultural trade were varied with the sub-sectors analyzed responding differently to the bilateral trade liberalization.

Assessing the environmental impact of changes in pesticide use on transgenic crops
Provedor de dados: 26
Autores: Kleter, G.A.; Kuiper, H.A.
Two main traits that have been introduced into genetically modified crops that are currently on the market, viz., herbicide and insect resistance, likely affect pesticide use on these crops. Various surveys have been carried out, such as those of the USDAERS and NCFAP, comparing the pesticide use on genetically modified versus conventional crops. Environmental indicators for pesticides may aid in comparing the outcomes of such assays in terms of environmental impact. Previously we applied one indicator, the Environmental Impact Quotient, to pesticide-use data for commercial biotech crops from a recent survey by NCFAP and found that, by this method, the impact paralleled the decreased use of pesticides. The output of many environmental indicators, while...

Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia
Provedor de dados: 5
Autores: Ferraris, Jocelyne; Pelletier, Dominique; Kulbicki, M; Chauvet, C.
We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish density were examined at the level of fish assemblage, accounting for habitat. Fish counts and habitat-related information were collected before and after the removal of reserve status, both inside and outside the reserve. Species groups were constructed on the basis of additional information on behavioural characteristics and taxonomy. The impact of the removal of reserve status was assessed by using 2 habitat proxies corresponding to 2 spatial scales and by considering several criteria for grouping species. Habitat...

This article compares how eliminating the U.S. cotton subsidy program and the Chinese cotton tariff-rate quota (TRQ) would affect the world cotton market. The results show China's TRQ has a greater negative impact on the world cotton market than do U.S. subsidies. Compared to a base-level estimate, the elimination of China's TRQ increases the world cotton price and increases the quantity of world cotton traded, whereas the elimination of U.S. cotton subsidies increases the cotton price (but less than under TRQ elimination) and decreases the world cotton trade. The combined effect of eliminating both programs is also shown.

Assessing the performance of auctions for the allocation of conservation contracts: Theoretical and computational approaches
Provedor de dados: 31
Autores: Hailu,   Atakelty; Schilizzi,   Steven; Thoyer,   Sophie.
There is a growing interest in using auctions for purchasing public goods from private agents. Auctions are being trialed in Australia and elsewhere to allocate conservation contracts. The expectation is that competitive bidding will reduce information rents and increase cost-effectiveness. This paper examines how auctions would perform under different assumptions regarding the rationality of bidders. A theoretical model requires bidders to be rational and use Nash equilibrium strategies, while an agent-based model assumes boundedly rational bidders learning from experience. The study illustrates the synergies between economic theory and agent-based modelling. Our findings provide a cautionary message regarding the performance of conservation auctions.

Assessing the Relationship Between Crop Choice and Land Use Change Using A Markov Model
Provedor de dados: 31
Autores: Hua,   Wei; Sohngen,   Brent; Hite,   Diane.
There is widespread concern among environmental and agricultural interest that land use change will affect the future productivity of the agricultural industry by utilizing highly productive land for development.  This paper considers the links between land use change and crop choices in order to analyze whether land use change is influencing crop choices.  In order to account for potential endogeneity between crop choices and land use choices, we develop a Markov Model that allows us to capture potential endogeneity between these two choices (land use and crop choice).  The Markov model is developed for the 12 Midwestern U.S. States using USDA NRI data at the county level.

Assessing the risk from mycotoxins for the organic food chain: results from Organic HACCP-project and other research
Provedor de dados: 21
Autores: Wyss, Gabriela.
Introduction:  Mycotoxins are toxic compounds produced by the secondary metabolism of toxic moulds in the Aspergillus, Penicillium and Fusarium genera occurring in food commodities and foodstuffs. The range and potency of mycotoxins make this group of naturally occurring toxins an ongoing animal health hazard and a constant risk for contamination of the food supply.    Mycotoxicoses are diseases caused by exposure to foods or feeds contaminated with mycotoxins. Mycotoxins exhibit a variety of biological effects in animals, such as liver and kidney toxicity, central nervous system effects or estrogenic effects. There are differences between animals with regard to the susceptibility towards different mycotoxins. Poultry secrete mycotoxins relatively fast...

Assessing the sustainability of a stockless arable rotation (OF0318)
Provedor de dados: 21
Autores: Cormack, William.
The majority of organic conversions have been on upland grass-based livestock farms resulting in a shortage of UK-grown cereals and pulses. Across northern Europe, conventional agriculture has developed a specialised structure with many areas having no livestock, or knowledge or facilities to support livestock. Sustainable organic production on these farms has particular challenges for nutrient supply, for the management of weeds, pests and diseases and for economically viability.    This report covers a three and a half year period (four crop harvests) of a longer-term programme of work, which began in 1990. The overall objective was to identify and overcome factors limiting the sustainability of a stockless arable rotation. Specific objectives were to 1)...

Disease assessment is the basis for describing disease resistance characteristics of commercial varieties in national variety lists for all crops where disease is considered a problem. It is well known that ‘disease’ in a specific situation depends on a whole range of interacting hosts, pathogens and environmental conditions. However, the biological complexity conflicts with the wish to express disease resistance characteristics of a variety as a single score per disease. This problem will be illustrated by basic dynamics of growth and senescence of both host and pathogen over time. Disease expressed in terms of absolute diseased leaf area, disease relative to total leaf area or green leaf area will be discussed in general. Two particular problems in...

The urgent need to improve livestock productivity in  sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important...

The economy of Zimbabwe has been in shambles since 1991. Output has declined in most of the production sectors, leading to many job losses. Current debates on the problems facing the economy have focused on poor government's incentives and excessive interventions as major constraints of economic development. The government of Zimbabwe, on the other hand has emphasized an agriculturally led economic recovery programme. Specifically, the government has undertaken land reform and investment policies aimed at promoting small-holder agriculture in Zimbabwe. Is this a justifiable action taken by the government? The answer to this question necessitated the use of the 1991 micro SAM for Zimbabwe to empirically analyze the impact of small-holder agriculture on the...

Autores: Touratier, Franck; Goyet, C; Coatanoan, Christine; Andrie, C.
With a limited number of properties (salinity, temperature, total dissolved inorganic carbon, total alkalinity, and oxygen) from a recent cruise in the tropical Atlantic Ocean, We use the simple and recent approach TrOCA (Tracer combining Oxygen, inorganic Carbon, and total Alkalinity) to estimate the distribution of anthropogenic CO2 along three latitudinal sections. In order to assess the quality of the anthropogenic CO2 distribution, results from the method are compared to the CFC-11 measurements. We discuss the large-scale distribution of the main water masses of the tropical Atlantic Ocean in the light of the anthropogenic CO2 and the CFC-11 distributions. Keeping in mind that the anthropogenic CO2 emission began similar to 60 years earlier than that...

We investigate the applicability of the present-value asset pricing model to fishing quota markets by applying instrumental variable panel data estimation techniques to 15 years of market transactions from New Zealand's individual fishing quota market. In addition to the influence of current fishing rents (as measured by lease prices), we explore the effect of market interest rates, risk, and expected changes in future rents on quota asset prices. Controlling for these other factors, the results support a fairly simple relationship between quota asset and contemporaneous lease prices. Consistent with theoretical expectations, the results indicate that quota asset prices are positively related to declines in interest rates, lower levels of risk, expected...

Autores: BENAVIDES,A. GONZALO; VELOSO,ALBERTO; JIMÉNEZ,PAULINA; MÉNDEZ,MARCO A.
The assimilation efficiency of Bufo spinulosus tadpoles from four localities in Chile was evaluated for two different temperatures (15 and 25 ºC) and two different diets (low nutritional quality diet (LQD): 22.28 mg g N-1; high nutritional quality diet (HQD): 47.53 mg g N-1) using ash as a marker of digestion. Results showed that geographic origin did not affect assimilation efficiency, while the relationship observed between temperature and diet quality was significant. Assimilation efficiency was greater for the HQD when tadpoles were maintained at 15 °C, instead significant differences were not found between diets for tadpoles maintained at 25 °C. Our results suggest that the effect of temperature on digestive processes is more relevant than its effect...

Associação entre El Niño Oscilação Sul e a produtividade do milho no Estado do Rio Grande do Sul
Provedor de dados: 86
Autores: Berlato,Moacir Antonio; Farenzena,Homero; Fontana,Denise Cybis.
A alta variabilidade interanual da produtividade de milho, no Rio Grande do Sul, é determinada, principalmente, pela variabilidade da precipitação pluvial, e esta, em grande parte está associada ao fenômeno El Niño Oscilação Sul (ENOS). A disponibilidade, hoje, de previsões sazonais do ENOS faz vislumbrar a possibilidade de uso dessas informações para minimizar prejuízos e maximizar a produtividade. Há necessidade, porém, de se avaliar a vulnerabilidade da produtividade do milho a esse fenômeno. O objetivo deste trabalho foi quantificar a associação entre a produtividade de milho e a variabilidade da precipitação pluvial, causada pelo ENOS. Para a análise, foram tomadas séries históricas de produtividade, de precipitação pluvial mensal, de ocorrência das...

Association of a PIT1 gene polymorphism with growth hormone mRNA levels in pig pituitary glands
Provedor de dados: 74
Autores: Franco,Maurício Machaim; Antunes,Robson Carlos; Oliveira,Katiana Mello de; Pereira,Cícero Donizete; Biase,Fernando Henrique; Nunes,Francis de Morais Franco; Goulart,Luiz Ricardo.
Fourty-six non-castrated, halothane-free, male Landrace pigs were genotyped by PCR-RFLP for the Rsa I polymorphism in the PIT1 gene and classified into AA and AB genotypes. Total RNA was extracted from the pituitaries and the relative quantities of growth hormone (GH) mRNA were determined by semi-quantitative RT-PCR. Pigs with the AB genotype had higher levels of GH mRNA than those with the AA genotype (p = 0.034; Kruskal-Wallis test). This result suggests that the Rsa I polymorphism may be involved in Pit-1 protein expression or function, which in turn may influence GH transcription and expression. Thus, the Rsa I PIT1 gene polymorphism in this pig line may be used as a molecular marker to identify higher GH expression and possibly select for carcass and...

Autores: Pereira,Andréa Pozzi; Alencar,Maurício Mello de; Oliveira,Henrique Nunes de; Regitano,Luciana Correia de Almeida.
The Canchim beef cattle (5/8 Charolais + 3/8 Zebu) has been selected for meat production in Brazil since late 1950. In the present work the effects of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) polymorphisms were investigated in 688 animals born between 1998 and 2000. These animals belonged to two genetic groups, i.e., traditional and new lineages. Genotype effects on expected breeding values for birth weight (BW), weaning weight (WW) and yearling weight (YW) were investigated by the least square method. Significant effects were found for GH genotype on YW (p &lt; 0.05), with positive effects associated with the LV (leucine/valine) genotype. For IGF-1 genotypes, significant effects were found on BW (p &lt; 0.01) and YW (p &lt; 0.01)....

We studied the phenotypic effects of polymorphisms at the MYF5 gene in a divergent F2 swine population and found that one polymorphism was due to an insertion and another to a deletion. The genotypes of 359 F2 animals were obtained and the Normal/Normal (NN) and Normal/Insertion (NI) genotypes analyzed to determine associations with phenotypic data for performance, carcass and meat quality traits. Significant differences were observed (p &lt; 0.05) between NN and NI animals for drip (NN = 3.14 ± 1.56; NI = 3.69 ± 2.78%), cooking (NN = 32.26 ± 2.41; NI = 33.21 ± 2.31%) and total loss (NN = 34.16 ± 2.63 and NI = 34.97 ± 2.08%). The Deletion marker was not statistically tested. The results indicate that the allelic variant Insertion is associated with a...

Asymetric Price Transmission in the Spanish Lamb Sector
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria.
This paper aims to investigate the non-linear adjustments of prices between farm and retail prices in the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a three-regime Threshold Autoregressive Model. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted along the marketing chain. In the short-run, price adjustments between the farm and the retail levels are asymmetric and are representative of a demand-pull transmission mechanism. On the other hand, retailers benefit from any shock, whether positive or negative, that affects supply or demand conditions.

Asymmetric Willingness-to-Pay Distributions for Livestock Manure
Provedor de dados: 31
Autores: Norwood,   F. Bailey; Luter,   Ryan L.; Massey,   Raymond E.
The Environmental Protection Agency's new Concentrated Animal Feeding Operations (CAFO) regulations are forcing some farms to export livestock manure to off-farm acres. The regulation compliance cost depends on the willingness of neighboring crop producers to accept or pay for the manure. This study estimates a manure willingness-to-pay distribution for crop producers using a contingent valuation mail survey. A flexible parametric distribution is borrowed from the crop yield literature, which shows that manure willingness to pay is left-skewed. Most crop producers in our sample will pay a positive price close to the savings in commercial fertilizer, but approximately 25% require a payment before accepting manure.

Asymmetrical leaves induced by water deficit show asymmetric photosynthesis in common bean
Provedor de dados: 61
Autores: Souza,Gustavo Maia; Viana,Juliana de Oliveira Fernandes; Oliveira,Ricardo Ferraz de.
In this study we tested the hypothesis that leaf asymmetric growth induced by water deficit in common bean (Phaseolus vulgaris L.) might be correlated with different net photosynthesis rates between the two opposed leaflets (right and left) considering a bilateral symmetric plane. In order to induce developmental instability, the drought-sensitive common bean genotype "Jalo Precoce" was subjected to periods of suspended irrigation during its vegetative growth. Developmental instability was evaluated by measurements of leaflets asymmetry, and the effects of drought on gas exchanges were taken in both symmetrical leaflets (right and left) in relation to the central leaflet. Water deficit induced an increase of 80 % in leaf asymmetry. Net photosynthesis of P....

This study looked at the dynamics of conditional correlations and hedging strategies in the US main cotton producing regions. A two-step procedure was utilized to model, estimate, and analyze volatility, conditional correlations, and the optimal hedge ratios using spot prices in the Delta, Southeast, Southern Plains, and the Southwest regions and the New York commodity exchanges December futures contracts.  The results indicate that volatilities in most of the regions are asymmetric and persistent. The derived conditional correlations and the optimal hedging ratios are dynamic although they do not have unit root. Moreover, the changes in agricultural policies altered the dynamics of correlations and producers' hedging strategies in the Delta, Southeast,...

At What Rate Do Farmers Substitute Manure For Commercial Fertilizers?
Provedor de dados: 31
Autores: O'Donoghue,   Erik J.; MacDonald,   James M.; Nehring,   Richard F.
Water quality has implications for the health of our ecosystem and the welfare of our population.  Agriculture is one of the major contributors of non-point source pollution that contaminates our nation's water supplies.  Understanding how farmers substitute manure for commercial fertilizers allows us to better understand the level of nitrogen that enters the soil and can seep into our waterways.  In this paper, we explore the factors that help determine farmers' substitution rates between the two types of fertilizers.  Location, crop type, and time all could play important roles.  We analyze USDA farm level survey data for both crop and livestock farms covering the years 1996 to 2002 to create substitution rate estimates used on corn, soybean, and wheat...

Cardiovascular disease is the primary cause of death in Brazil. Recent studies have shown that low birth weight and preterm birth are linked to a higher prevalence of cardiovascular disease. The aim of the present study was to compare the levels of lipids and apolipoproteins and atherogenic indexes between term and near-term newborn infants. A sample of umbilical cord blood was obtained from 135 newborns (66 males) divided into two groups: 25 near-term neonates (35-36.6 weeks of gestational age) and 110 term neonates (37-42 weeks of gestational age).

Atherosclerosis in aged mice over-expressing the reverse cholesterol transport genes
Provedor de dados: 56
Autores: Berti,J.A.; de Faria,E.C.; Oliveira,H.C.F.
We determined whether over-expression of one of the three genes involved in reverse cholesterol transport, apolipoprotein (apo) AI, lecithin-cholesterol acyl transferase (LCAT) and cholesteryl ester transfer protein (CETP), or of their combinations influenced the development of diet-induced atherosclerosis. Eight genotypic groups of mice were studied (AI, LCAT, CETP, LCAT/AI, CETP/AI, LCAT/CETP, LCAT/AI/CETP, and non-transgenic) after four months on an atherogenic diet. The extent of atherosclerosis was assessed by morphometric analysis of lipid-stained areas in the aortic roots. The relative influence (R²) of genotype, sex, total cholesterol, and its main sub-fraction levels on atherosclerotic lesion size was determined by multiple linear regression...

Atlantic bluefin tuna: population dynamics, ecology, fisheries and management
Provedor de dados: 5
Autores: Fromentin, Jean-marc; Powers, Joseph.
Both old and new information on the biology and ecology of Atlantic bluefin tuna have confronted scientists with research challenges: research needs to be connected to current stock-assessment and management issues. We review recent studies on habitat, migrations and population structure, stressing the importance of electronic tagging results in the modification of our perception of bluefin tuna population dynamics and behaviour. Additionally, we question, from both scientific and management perspectives, the usefulness of the classical stock concept and suggest other approaches, such as Clark's contingent and metapopulation theories. Current biological information confirms that a substantial amount of uncertainty still exists in the understanding of...

A adsorção de metais pesados no solo, tais como o cádmio e o cobre, é controlada por reações químicas e por processos físicos e biológicos. A retenção de metais pesados no solo pode diminuir a biodisponibilidade desses elementos no sistema solo-solução. Avaliou-se a adsorção de cádmio e de cobre em amostras de horizontes superficiais e subsuperficiais de oito solos, sendo cinco Latossolos, dois Nitossolos e um Argissolo. Correlacionou-se a adsorção máxima estimada pela equação linearizada de Langmuir com vários atributos dos solos. No horizonte A, a adsorção máxima de Cd foi correlacionada positivamente com a CTC total, com a superfície específica e com os teores de teores de argila, de silte, de óxidos de ferro bem cristalizados e de alumínio total,...

The somatic cloning by transfer of the nuclei of differentiated adult cells to previously enucleated oocytes is a promising technique for the production of embryos of high genetic value. The better mastering of somatic cloning gives us the possibility to produce embryos from endangered species. The huemul is an Andean native deer, that has been declared an endangered species, it holds a great patrimonial value and it is a Chilean national emblem. In Chile the huemul has the status of protected animal on thirteen Parks and National Reserves managed by Corporacion Nacional Forestal (CONAF). This protection, however, is considered insufficient due to the few geographical connections between the different protected areas. Furthermore, a great proportion of...

A chimeric yellow fever (YF)-dengue serotype 2 (dengue 2) virus was constructed by replacing the premembrane and envelope genes of the YF 17D virus with those from dengue 2 virus strains of Southeast Asian genotype. The virus grew to high titers in Vero cells and, after passage 2, was used for immunogenicity and attenuation studies in rhesus monkeys. Subcutaneous immunization of naive rhesus monkeys with the 17D-D2 chimeric virus induced a neutralizing antibody response associated with the protection of 6 of 7 monkeys against viremia by wild-type dengue 2 virus. Neutralizing antibody titers to dengue 2 were significantly lower in YF-immune animals than in YF-naive monkeys and protection against challenge with wild-type dengue 2 virus was observed in only 2...

Attitude of Flemish Farmers Towards Alternative Business Governance Structures
Provedor de dados: 31
Autores: Calus,   Mieke; Van Huylenbroeck,   Guido.
The Flemish agriculture is characterised by family farms in sole ownership.  Alternative business governance structures occur in only 7 % of the cases, although they have advantages on fiscal, family and property grounds. The reason why partnerships don't work in Flemish agriculture are mainly situated at the knowledge and perception level of the farmers.  The knowledge of the different structures exists only in a limited group of farmers. The subjective perception of governance structures enhances the limitation of transition to alternative business governance structures. Partnerships will be adapted by farmers who have a higher knowledge of alternative business governance structures and accept that the higher administration is compensated by a lower risk.

Autores: Vermeulen,   Hester; Kirsten,   Johann F.; Doyer,   Ockert T.; Schonfeldt,   H.C.
The introduction of genetically modified (GM) food products to food markets around the world, has led to considerable controversy. In many cases consumer attitudes and perceptions of GM food products were revealed as fears, concern for, and avoidance of the new technology. The importance of GM foods in South Africa is increasing, even though the GM Food debate lags behind many other (often more developed) parts of the world. This paper investigates the knowledge, attitudes and acceptance of urban South African white-grain maize consumers regarding GM maize. Conjoint- and cluster analysis were used to develop clusters/market segments among the urban consumers of white maize. A range of additional questions was used to develop profiles of the identified...

Auctioning Payment Entitlements
Provedor de dados: 31
Autores: Nielsen,   Kurt.
Payment entitlements is a new commodity that arises from the new European common agricultural policy. The agricultural subsidies are decoupled from the actual production and replaced by the so-called payment entitlements. A payment entitlement has a farm specific value and may be freely traded. This paper discusses the complexity of this new market and suggests an auction that simplifies the complexity. The suggested auction allows a buyer to simultaneously bid on all payment entitlements. The prices are found by a tatonnement that monotonically approximates the equilibrium prices for the different types of payment entitlements for sale. The auction enhances the competition and efficiency of the market, which is essential for the individual members of the...

While sufficient statistical data in the conventional food market enables decision-makers to opt for investments or policies on a well-founded basis, this data is lacking in the organic food market. A European Concerted Action project in co-operation with the EU statistical office, EUROSTAT, and funded by the European Union aims there-fore at developing a framework for collection and processing reliable and comprehen-sive data on organic markets. The first phase of the project with the aim of analysing the current situation and developing proposals is accomplished. The results are a number of detailed and specific suggestions to improve the data situation on the national and international level.

Durch regelmäßige und risikoorientierte Probenziehung von Obst und Gemüse im Naturkosthandel konnten mögliche Pestizid-Belastungen aufgespürt, Ursachen recherchiert und abgestellt werden. Im Vordergrund stand die Analyse auf Pflanzenschutz-, Schädlingsbekämpfungs- und Lagerschutzmittel. Mit Abschluss des Projekts liegt erstmals eine umfangreiche Datensammlung zur Pestizidbelastung von ökologisch erzeugtem Obst und Gemüse vor.    Während der Projektlaufzeit wurden 677 Obst- und Gemüseproben auf jeweils mindestens 250 Pestizide untersucht. Die Ergebnisse belegen deutlich, dass ökologisch produziertes Obst und Gemüse signifikant weniger...

Autores: Mäder, Paul; Fliessbach, Andreas; Berner, Alfred.
Die Aufbereitung von Festmist durch Rotte oder Kompostierung führt zwar zu erheblich höheren Verlusten an Stickstoff und organischer Substanz. Trotzdem schneidet aufbereiteter Mist in Versuchen besser ab als Stapelmist. Er versorgt die Pflanzen besser mit Stickstoff und bringt den Humushaushalt langfristig ins Lot.

Ausência de Trichinella spiralis em suínos adultos abatidos em Palmas, Estado do Paraná, Brasil
Provedor de dados: 65
Autores: Daguer,Heitor; Geniz,Pedro Valdir; Santos,Adriano Vaz dos.
Foram examinadas amostras de 3.774 suínos adultos, abatidos sob inspeção federal entre os anos de 2002 e 2004 na cidade de Palmas, Estado do Paraná, Brasil, utilizando-se a técnica da digestão artificial de amostras coletivas com agitador magnético para pesquisa de larvas de Trichinella spiralis. Os animais eram provenientes de 68 municípios dos três estados da região Sul do Brasil. A técnica utilizada seguiu as recomendações européias e as amostras examinadas consistiam de fragmentos musculares do masseter, base da língua e diafragma de cada animal. Não foram detectadas larvas do parasita nos animais examinados, sugerindo que a infecção por T. spiralis não ocorre nas criações de suínos examinadas.

Aussichten des Einsatzes von Migrationsbarrieren zur Abwehr von Wühlmausschäden im ökologischen Obstbau
Provedor de dados: 21
Autores: Walther, Bernd; Pelz, Dr. Hans-Joachim.
Cyclic vole species, particularly the Water vole (Arvicola terrestris), cause substantial agricultural damage throughout their wide geographical range. In organic pomiculture synthetic pesticides are not allowed. Trapping and fumigation remain the only applicable measures for managing voles but require a lot of time and personal skills. The success of using these methods is reduced by the fast recolonisation of the empty areas. To stop the permanent overground immigration of voles a mechanical barrier system was developed and tested in enclosures and at two study sites in Baden-Wuerttemberg and Rhineland-Palatinate between October 2002 and October 2003. The barrier, consisting of a low fence of whire mesh or polyolefin foil, reached 20 cm below and 30 cm...

Ausstieg aus der ÖPUL-Maßnahme biologische Wirtschaftsweise
Provedor de dados: 21
Autores: Darnhofer, Ika; Eder, Michael; Schmid, Johann; Schneeberger, Walter.
The end of the first five-year contract period of the Austrian Agri-environmental Program (ÖPUL) caused a number of farmers to opt out of the measure organic farming at the end of 1999 and in the following years. A survey was made in 2003 to explore the reasons for reverting to conventional farming. The three most important reasons were the high cost of organic grain for feed, the lack of price premia for organic products (mostly beef and milk) and the frequency of changes in organic standards. Most respondents operate grassland-based dairy farms in Alpine regions. The average size of the farms opting out was 12,0 ha.

Austria established an environmental program (ÖPUL) for agriculture in 1995, including direct payments for organic farming. To participate in this measure farmers have to commit themselves to a five year period. In 1999 a survey was conducted to find out, to which extent organic farmers intended to drop out of the measure organic farming and to collect information about their reasons for this intention. In 2002 a new survey was carried out to compare the intentions with the actual developments. In 2004 additional information was collected through telephone interviews. The aim of this study was a) to compare the intended with the actual behaviour, b) to compare the ex ante and ex post expressed reasons for leaving the measure organic farming and c) to find...

Australasian environmental economics: contributions, conflicts and ‘cop-outs’
Provedor de dados: 31
Autores: Bennett,   Jeffrey W.
Australian and New Zealand environmental economists have played a significant role in the development of concepts and their application across three fields within their subdiscipline: non-market valuation, institutional economics and bioeconomic modelling. These contributions have been spurred on by debates within and outside the discipline. Much of the controversy has centred on the validity of valuations generated through the application of stated preference methods such as contingent valuation. Suggestions to overcome some shortcomings in the work of environmental economists include the commissioning of a sequence of non-market valuation studies to fill existing gaps to improve the potential for benefit transfer.

Farms in the EU receive considerable support via the Common Agricultural Policy. Support to organic and conventional farms are analysed covering a wide range of different support measures of the Common Agricultural Policy. Results show that the design of the Common Market Organisations can pose a disadvantage to organic farming systems, even though developments of the last two CAP Reforms (year 1992 and 2000) and the latest reform (2003) have reduced the discrimination of extensive farming systems and provide an opportunity to design suited measures to meet part of the needs of organic farms.

Auswirkungen der Beregnung von Kartoffeln in Abhängigkeit der Stallmistdüngung auf den Ertrag, die Qualität sowie die Verarbeitungseignung zu Pommes frites und Chips
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Taube, Friedrich; Haase, Norbert U.
Ökologisch erzeugte Kartoffeln, die zur Verarbeitung zu Pommes frites oder Chips genutzt werden sollen, müssen besondere Qualitätseigenschaften aufweisen. So wird beispielsweise ein mittlerer bis hoher Stärkegehalt bei gleichzeitig niedrigen Gehalten an reduzierenden Zuckern gefordert. Um den von der verarbeitenden Industrie geforderten Qualitätsansprüchen gerecht zu werden, ist neben einer ausgewogenen Düngung gerade auf leichten Böden auch eine ausreichende Wasserversorgung entscheidend, die oft nur über Beregnung sichergestellt werden kann. Unter den Fragestellungen, ob organischer Dünger (Stallmist) durch die Beregnung besser von den Verarbeitungskartoffeln ausgenutzt werden kann und inwiefern Ertragsstruktur und die Qualitätsparameter von...

Der Versuch wurde durchgeführt, um den Effekt der Fütterung von unterschiedlichen Körnerleguminosenanteilen ohne die Verwendung von Ölkuchen oder konventionellen Komponenten im Endmastfutter zu quantifizieren. Es traten keine signifikanten Unterschiede in der Mast- und Schlachtleistung sowie der Fleischqualität auf zwischen den drei Futtergruppen, deren Endmastrationen 40 % Erbsen, 50 % Erbsen und 33 % Erbsen + 15 % blaue Süßlupinen enthielten. Alle Tiere zeigten gute Leistungen, die jedoch bei einem späteren Beginn des Einsatzes des Endmastfutters bei 70 kg LG anstelle von 50 kg LG noch besser gewesen wären. Die Verwendung von 15 % blauen Süßlupinen hatte keine negativen Einflüsse auf die Leistung und die Fleischqualität zur Folge.

Organic farming has expanded rapidly in Europe during the last decade. In view of the agricultural policy trends, the current socio-political climate and a continuously growing demand for organic products, a further expansion of organic farming seems likely. In view of these prospects, the objective of this study is to provide a quantitative assessment of the impacts of a significant expansion of organic farming in the European Union on agricultural production, markets and the environment. Using and extending the EU-wide agricultural sector model CAPRI, different policy scenarios for a conversion of organic farming to 20 % of the agricultural area in the EU are analysed. The results indicate that such an expansion has a significant effect on several...

The reduction of soil tillage intensity is of special interest for organic farmers. To study the influence of reduced tillage on soil properties and weed vegetation field plots were set up in 1992 on the FAM Research farm in southern Germany. From 1999 till 2002 weed vegetation was recorded including soil seed bank, plant density, number of flowering plants and biomass. Reduced tillage intensity did not influence the weed population dymamics but did influence the species composition. Elymus repens, Apera spica-venti and Poa annua were promoted by a tillage regime that omitted deep ploughing in four of seven years. The cultivation of grass/ley mixtures plays an important role in crop rotations of organic farming systems e.g. as part of the weed management....

Autoimmunity and molecular mimicry in tropical spastic paraparesis/human T-lymphotropic virus-associated myelopathy
Provedor de dados: 56
Autores: García-Vallejo,F.; Domínguez,M.C.; Tamayo,O.
Viruses share antigenic sites with normal host cell components, a phenomenon known as molecular mimicry. It has long been suggested that viral infections might trigger an autoimmune response by several mechanisms including molecular mimicry. More than 600 antiviral monoclonal antibodies generated against 11 different viruses have been reported to react with 3.5% of cells specific for uninfected mouse organs. The main pathological feature of tropical spastic paraparesis/human T-lymphotropic virus type I (HTLV-I)-associated myelopathy (TSP/HAM) is a chronic inflammation of the spinal cord characterized by perivascular cuffing of mononuclear cells accompanied by parenchymal lymphocytic infiltration. We detected the presence of autoantibodies against a 98- to...

Automatic extraction of road seeds from high-resolution aerial images
Provedor de dados: 42
Autores: Dal-Poz,Aluir P.; Do Vale,Giovane M.; Zanin,Rodrigo B.
This article presents an automatic methodology for extraction of road seeds from high-resolution aerial images. The method is based on a set of four road objects and another set of connection rules among road objects. Each road object is a local representation of an approximately straight road fragment and its construction is based on a combination of polygons describing all relevant image edges, according to some rules embodying road knowledge. Each one of the road seeds is composed by a sequence of connected road objects, in which each sequence of this type can be geometrically structured as a chain of contiguous quadrilaterals. Experiments carried out with high-resolution aerial images showed that the proposed methodology is very promising in extracting...

En enero del 2002 asumió el poder el Coronel Lucio Gutiérrez, triunfador en las elecciones  presidenciales en las que se presentó como candidato de la alianza del recientemente fundado Partido Sociedad Patriótica, integrado básicamente por elementos militares que participaron en las acciones que concluyeron con el derrocamiento de Jamil Mahuad, con fuerzas sociales emergentes como Pachacutik y la extrema izquierda encarnada en el MPD.  Su plataforma electoral se basó en el ofrecimiento de luchar contra la corrupción y hacer las cosas de manera diferente a lo que se había hecho en la vieja política, a la que se presentó como culpable, ante los electores, de todos los males. Sin duda caló su discurso, ya que el terreno abonado durante años, desprestigiando a...

Avaliação da DL50 e edema pulmonar induzido pelo veneno de Tityus serrulatus (Scorpiones; Buthidae) procedente da Bahia, Brasil
Provedor de dados: 49
Autores: Silva,Tiago F.; Casais-e-Silva,Luciana L.; Lira-da-Silva,Rejâne M.
O escorpião Tityus serrulatus é conhecido como a espécie mais importante, do ponto de vista médico, pois é o que causa os acidentes mais graves registrados para o território brasileiro. Este trabalho trata da caracterização do veneno do escorpião T. serrulatus, através da obtenção da DL50 e determinação da capacidade em induzir edema pulmonar, em ratos. O veneno foi obtido através de estímulo elétrico. A toxicidade foi determinada através da avaliação da DL50, pelo método de Finney (1971). Os valores demonstraram a baixa toxicidade do veneno (96,16 mg/camundongo), que corresponde a 3 - 7 vezes menos tóxico que venenos de espécimes de outras regiões do Brasil. O veneno testado também não induziu edema pulmonar, avaliado através da diferença entre o peso do...

Avaliação da interferência in vitro do extrato seco de berinjela (Solanum melongena L.) em testes laboratoriais
Provedor de dados: 38
Autores: Brietzig,E. G.; Falkenberg,M. B.; Freitas,S. F. T.
Cápsulas com berinjela têm sido usadas para reduzir colesterol. Estudos em animais apontaram significativa redução do colesterol total ou do LDL-colesterol, contudo em humanos os resultados não são conclusivos. Dada a presença na berinjela de antocianinas, de comprovada atividade antioxidante, seria possível que estes interferirem em determinações laboratoriais. Avaliou-se a interferência in vitro nas determinações de glicose, colesterol, triglicerídeos e ácido úrico. Os testes foram realizados com extrato seco de berinjela comercial, adicionado a soro calibrador comercial, em concentrações supraterapêuticas, e depois em concentrações terapêuticas para os analitos que apresentaram interferência significativa na concentração supraterapêutica. Como controles...

Provedor de dados: 94
Autores: Osipi,Elisete Aparecida Fernandes; Nakagawa,João.
Averiguou-se a influência de três condições ambientais na capacidade de armazenamento da semente do maracujá-doce (Passiflora alata Dryander): ambiente não controlado (embaladas em saco de papel), câmara seca (embaladas em saco de papel) e câmara fria (embaladas em saco de polietileno). Nesses tratamentos, avaliaram-se o teor de água e as porcentagens de germinação, de plântulas anormais, de sementes dormentes e a de mortas, no decorrer de seis meses e após um ano. A germinação não diferiu entre os ambientes de conservação durante os seis meses iniciais de armazenamento. Após doze meses, contudo, a conservação favoreceu as sementes com grau de umidade próximo a 10%, embaladas em sacos de polietileno e mantidas a 10 º C.

Avaliação da qualidade do abacaxi "Pérola" minimamente processado armazenado sob atmosfera modificada
Provedor de dados: 64
Autores: Santos,Juliana Costa Bueno; Vilas Boas,Eduardo Valério de Barros; Prado,Mônica Elisabeth Torres; Pinheiro,Ana Carla Marques.
Objetivou-se com este trabalho verificar o efeito da atmosfera modificada ativa sobre a qualidade do abacaxi minimamente processado. Assim, foram avaliadas as modificações físico-químicas, sensorial e microbiológica do abacaxi 'Pérola' minimamente processado submetido a diferentes atmosferas modificadas passiva e ativamente (controle - atmosfera modificada passiva; 5%O2 + 5%CO2 , 2%O2 + 10%CO2). A atmosfera com 2% O2 + 10% CO2 determinou menor perda de líquido drenado, embora tal perda tenha sido desprezível. A atmosfera modificada ativa preveniu o amaciamento do abacaxi minimamente processado, reduzindo a atividade da poligalacturonase e solubilização péctica. As variáveis pH e vitamina C não foram significativamente afetadas pela atmosfera modificada...

Autores: Pinheiro,Neuma Maria de Souza; Figueiredo,Evânia Altina Teixeira de; Figueiredo,Raimundo Wilane de; Maia,Geraldo Arraes; Souza,Paulo Henrique Machado de.
O processamento mínimo tem sido descrito como a manipulação, o preparo, embalagem e a distribuição de produtos agrícolas, através de procedimentos como seleção, limpeza, lavagem, descascamento e corte, que não afetem suas características organolépticas, agregando valor aos mesmos. Vários fatores limitam o consumo destes produtos, os quais estão envolvidos na sua vida útil, tais como: aumento da respiração e da produção de etileno, escurecimento enzimático, descoloração da superfície, perda de água e, sobretudo, alterações microbiológicas. No presente trabalho, o enfoque foi dado a este ultimo fator. Foram analisadas 20 amostras de goiaba, manga, melão japonês, mamão formosa e abacaxi minimamente processados e comercializados em supermercados da cidade de...

Provedor de dados: 53
Autores: Queiroz-Voltan,Rachel Benetti; Cabral,Luciane Perosin; Fazuoli,Luiz Carlos; Paradela Filho,Osvaldo.
A bactéria Xylella fastidiosa Wells et al. foi detectada pela primeira vez em cafeeiro no Brasil, em 1995, entretanto acredita-se que a cultura foi infectada por essa bactéria há muitos anos, embora os sintomas fossem atribuídos a um estresse nutricional. Até o momento têm sido realizados estudos principalmente com espécies de C. arabica e C. canephora, porém, em outras espécies do gênero, somente foi detectada sua presença. Neste trabalho, objetivou-se avaliar a proporção de elementos de vaso do xilema obstruídos, total e parcialmente, pela X. fastidiosa, naturalmente infectadas, em diferentes espécies de cafeeiro do Banco de Germoplasma do IAC, visando identificar material resistente a essa bactéria para ser utilizado no programa de melhoramento...

Autores: Jesus,Sandra Cerqueira de; Matsuura,Fernando Cesar Akira Urbano; Folegatti,Marília Ieda da Silveira; Cardoso,Ricardo Luis.
A industrialização pode ser uma opção para o aproveitamento de excedentes de produção e de frutos com aparência comprometida para consumo in natura, ao proporcionar aumento da vida-de-prateleira e agregação de valor ao produto. Frutos de diferentes variedades de bananeira (Musa spp.), obtidas em programas de melhoramento genético, podem apresentar características diferenciadas no que se refere à adequação à determinada forma de processamento. O objetivo deste trabalho foi avaliar o produto banana-passa, obtido a partir de frutos de diferentes genótipos de bananeira. Os genótipos avaliados foram: Caipira; Nanica; Pacovan e seus híbridos PV03-44 e PV03-76; Prata Anã e seus híbridos FHIA-18, Pioneira e Prata Graúda. O processamento da banana-passa incluiu a...

Autores: Barbosa,Leandro; Lopes,Paulo Sávio; Regazzi,Adair José; Guimarães,Simone Eliza Facioni; Torres,Robledo de Almeida.
Dados de 367 animais de uma população F2 de suínos foram utilizados na análise estatística, utilizando-se os componentes principais, para avaliação da possibilidade de redução da dimensionalidade do espaço multivariado em 33 características de carcaça. Dos 33 componentes principais, 17 apresentaram variância inferior a 0,7 (autovalor inferior a 0,7), que sugere 17 variáveis para descarte e correlação linear simples significativa com as demais, ou seja, foram redundantes. Com base nos resultados, recomenda-se que as seguintes variáveis sejam mantidas em experimentos futuros: idade ao abate; peso da meia-carcaça direita; comprimento da carcaça pelo Método Brasileiro de Classificação de Carcaça; maior espessura de toucinho na região da copa, na linha...

Autores: Blumer,Silvia; Pompeu Junior,Jorgino.
Laranjeiras Valência enxertadas em citrandarins e outros híbridos de trifoliata foram plantadas em 1988, em Itirapina (SP), num Latossolo Vermelho-Amarelo textura arenosa e conduzidas sem irrigação. O citrandarin Sunki x English (1.628), sem diferir estatisticamente de Cleópatra x Rubidoux (1.660), Cleópatra x English (710), Cleópatra x Swingle (715) e do trangpur Cravo x Carrizo (717), induziu a maior produção de frutos nas cinco primeiras colheitas do experimento (1991-1995), sendo que os três primeiros foram os mais produtivos nas três últimas colheitas. Os citranges Troyer e Carrizo foram significativamente inferiores aos citrandarins Sunki x English (1.628), Cleópatra x Rubidoux (1.660) e Cleópatra x English (710) em todos os anos, exceto 1994....

Avaliação de doenças da mangueira.
Provedor de dados: 14
Autores: LOPES, D. B.; MOREIRA, W. A.
A região semi-árida do Vale do Submédio São Francisco é responsável por mais de 90% do volume de manga exportado pelo Brasil. esta região a produtividade é elevada devido a características climáticas favoráveis e ao manejo fitotécnico intenso. No entanto, a intensificação do cultivo e algumas práticas de manejo vêm gerando ou agravando problemas fitossanitários, com conseqüente aumento de perdas de produção. As doenças que ocorrem na mangueira resultam em perdas quantitativas, ou seja, menor número de frutos formado, mas principalmente perdas qualitativas (redução no tamanho e apodrecimento de frutos). Este tipo de perda pode prejudicar o trânsito internacional da manga desta região.

As temperaturas baixas e geadas que ocorrem na Região Sul, durante a estação fria, determinam uma diminuição em quantidade e qualidade das pastagens. Para suprir as necessidades dos animais nos períodos de escassez de forragem, a silagem de milho tem sido muito utilizada. Tem sido apontada a existência de diferenças entre genótipos de milho quanto à produção e qualidade da silagem obtida. O objetivo deste trabalho foi identificar o potencial de híbridos comerciais de milho para produção de silagem na Região Sul do Brasil. Vinte e um híbridos foram testados em sete locais (Cascavel, Chapecó, Ijuí, Lages, Ponta Grossa, Teutônia e Urussanga), em delineamento de blocos casualizados com três repetições. Foram avaliados a produção de matéria seca e o potencial...

Avaliação de matrizes bovinas no Pantanal.
Provedor de dados: 14
Autores: ABREU, U. G. P. de; SERENO, J. R. B.
No início do século XX inicou-sse a introdução de gado zebu, de origem indiana (Bos taurus indicus) no Pantanal. A partir de então, por meio de cruzamentos contínuos, as raças zebuínas absorveram praticamente toda a população do Tucura (Bos taurus taurus) que era o tipo predominante na região, introduzido no Século XVI (Mazza et al., 1994). Atualmente, o rebanho existente no Pantanal é zebuíno com predominância da raça Nelore, embora, recentemente, foram registradas algumas iniciativas com relação ao uso de raças compostas e de cruzamentos entre raças européias e zebuínas (Rosa, 1997). A população total é de aproximadamente 3,8 milhões de cabeças, sendo 2,8 milhões no Pantanal Sul Mato-Grossense e 1 milhão no Pantanal do Estado de Mato Grosso.

Autores: Feres,Fabíola; Souza,Anete P. de; Amaral,Maria do Carmo E. do; Bittrich,Volker.
Foram comparadas metodologias para preservação de amostras de folhas de plantas de savanas neotropicais, visando a posterior obtenção de DNA de alta qualidade para estudos moleculares. Foram também testadas diferentes metodologias para extração de DNA das amostras investigadas. A qualidade do DNA extraído foi avaliada através de dois métodos: por digestão, utilizando-se três enzimas de restrição e através da amplificação do gene mitocondrial cox3 (subunidade III da citocromo oxidase) por PCR. Os resultados revelaram que, para as plantas de savanas investigadas, a metodologia de preservação de amostras mais comumente empregada pelos botânicos (desidratação rápida usando sílica-gel) não é a mais eficiente. Os resultados obtidos demonstram a importância de...

No processamento de conservas de palmito (Bactris gasipaes), a acidificação deve ser aplicada com eficiência, principalmente, para prevenir o desenvolvimento da bactéria Clostridium botulinum. Considerando este importante preceito, a pesquisa avaliou a eficiência de três procedimentos de acidificação no processamento, os quais foram estimados em pH 4,3, 4,2 e 3,9, para abaixar o pH do palmito fresco até o pH de equilíbrio nas conservas, que deve ser igual ou abaixo de 4,5. Apenas a acidificação que teve o pH 4,3 por estimativa produziu, em algumas conservas, valores de pH superiores, à 4,5. A conserva processada com salmoura de 4% foi a preferida, seguida pela de 3%. Foi marcante o paladar adocicado, característico do palmito fresco, apenas nas conservas...

Autores: QUEZADO-DUVAL, A. M.; LOPES, C. A.; JUNQUEIRA, N. T. V.
O pôrometro de pós-colheita é um instrumento para medir transpiração, resistência difusiva e déficit de pressão de vapor por manometria a volume constante e por volumetria a pressão constante. É constituído de uma câmara de transpiração com fechamento hermético contendo um suporte de amostras sobre um ventilador e externamente um manômetro de coluna de água com pipeta graduada móvel. Sob temperatura constante, o déficit de pressão de vapor (.P), e o volume de vapor de água (.V) foram proporcionais aos volumes de água vaporizados. Com o uso de um excesso de água este aumento da pressão de vapor iguala-se, em módulo, ao déficit de pressão de vapor do ar na câmara de transpiração. Para amostras do ar atmosférico no laboratório, o déficit de pressão de vapor...

Avaliação de resistência ao oídio em genótipos de videira
Provedor de dados: 64
Autores: Ribeiro,Valtemir Gonçalves; Camargo,Umberto Almeida; Maia,João Dimas Garcia.
Nos municípios de Bento Gonçalves, RS, e Jales, SP, sob condições de casa-de- vegetação e campo, respectivamente, foram avaliados para resistência ao Oídio, acessos do Banco Ativo de Germoplasma (BAG) pertencentes à Embrapa Uva e Vinho. Os critérios para avaliação foram de acordo com as escalas de notas propostas pelos IPGRI/UPOV/OIV (1997). Comparações com as testemunhas Vitis vinifera 'Thompson Seedless' e 'Itália' demonstraram a existência de vários acessos resistentes, possuindo como base genealógica cultivares híbridas nativas americanas, e, a avaliação dos acessos sob ambiente de casa-de-vegetação foi a mais eficiente para expressar o grau de suscetibilidade ao patógeno.

Avaliação do módulo de elasticidade da madeira com uso de método não-destrutivo de vibração transversal
Provedor de dados: 70
Autores: Targa,Luiz A.; Ballarin,Adriano W.; Biaggioni,Marco A. M.
Numerosas pesquisas têm estudado os métodos não-destrutivos de avaliação de materiais e sua aplicação àqueles de matrizes complexas, como é o caso da madeira. Um dos primeiros métodos não-destrutivos investigados para aplicação nesses casos foi o da vibração transversal. Apesar de sua concepção simples, e a despeito dos grandes avanços obtidos nessa área com outros métodos, como, por exemplo, o ultra-som, o método de vibração transversal para a determinação do módulo de elasticidade da madeira revela-se como de grande potencial de aplicação, sobretudo pela precisão do modelo matemático a ele associado e pela possibilidade de sua aplicação a peças de dimensões estruturais (in-grade testing). Neste trabalho, apresenta-se o uso desse método na determinação do...

Avaliação e adaptação do Índice de Severidade de Seca de Palmer (PDSI) e do Índice Padronizado de Precipitação (SPI) às condições climáticas do Estado de São Paulo
Provedor de dados: 53
Autores: Blain,Gabriel Constantino; Brunini,Orivaldo.
O Índice de Severidade de Seca de Palmer (PDSI) acusa o início de uma seca quando a precipitação pluvial de uma região diminui consideravelmente em relação a que seria climatologicamente esperada. Tal déficit é ponderado por um fator K de caracterização climática. Com base no ajuste de séries de precipitação à distribuição gama, o Índice Padronizado de Precipitação (SPI) quantifica o excesso ou o déficit de chuva, acumulados em diferentes escalas de tempo, em um determinado local. O presente trabalho avaliou e adaptou a metodologia do PDSI e do SPI às condições climáticas do Estado de São Paulo e comparou seus valores a parâmetros do balanço hídrico climático de treze localidades. De maneira geral, essa comparação foi realizada entre os quantificadores e o...

Avaliação econômica de alternativas de investimentos no agronegócio da uva no meio oeste Catarinense
Provedor de dados: 94
Autores: Kreuz,Carlos Leomar; Souza,Alceu; Schuck,Ênio; Petri,José Luiz.
Este artigo analisa as expectativas de retorno associadas ao agronegócio uva para vinho e para suco, no Meio Oeste Catarinense. Detalham-se os investimentos, os custos de produção e a rentabilidade financeira inerentes a esta atividade, tendo-se por base a produção de uva para vinho e para suco, em três sistemas de sustentação: latada, manjedoura e espaldeira. A metodologia utilizada, baseada no fluxo de caixa descontado, consistiu na geração de indicadores de retorno e risco. Apesar da leve supremacia da produção de uva destinada para vinho, os indicadores calculados sinalizam para uma rentabilidade baixa tanto para o caso do vinho como para o suco.

Avaliação in vitro da eficácia de acaricidas sobre Boophilus microplus (Canestrini, 1887) (Acari: Ixodidae) de bovinos no município de Ilhéus, Bahia, Brasil
Provedor de dados: 65
Autores: Campos Júnior,Dunezeu Alves; Oliveira,Paulo Roberto de.
O carrapato Boophilus microplus é a espécie de maior distribuição geográfica e importância econômica para os países produtores de bovinos em áreas tropicais e sub-tropicais do planeta. No Brasil, a Região Nordeste apresenta algumas áreas mais favoráveis para as infestações do gado. O controle químico ainda é a forma mais eficaz de combate deste ectoparasita, mas o manejo inadequado dos acaricidas tem contribuído com o aparecimento de resistência de populações aos produtos disponíveis no mercado. O município de Ilhéus, na Região Cacaueira da Bahia, vem incrementando sua atividade pecuária em substituição à lavoura cacaueira devastada. Foram realizados 30 testes de imersão in vitro (biocarrapaticidogramas) com fêmeas ingurgitadas de B. microplus colhidas em...

Provedor de dados: 70
Autores: Rossi,Luiz A.; Cardoso,Paulo E. dos R.; Beraldo,Antonio L.
Neste trabalho, apresenta-se uma proposta alternativa para o sistema de aquecimento de piso por resistência elétrica em granjas de aves e suínos. Após o dimensionamento do sistema, foram confeccionadas placas com argamassa de cimento, areia e casca de arroz, com diferentes traços, a fim de avaliar esse material alternativo de construção, sendo construído um controlador eletrônico de temperatura para dar mais autonomia ao sistema de aquecimento. O sistema mostrou-se eficiente no controle da temperatura da placa. Dentre os traços analisados, aquele com a placa mista de argamassa convencional e casca de arroz demonstrou melhor desempenho.

Aves de la parte baja del Río Sinú, Caribe colombiano; inventario y ampliaciones de distribución
Provedor de dados: 20
Autores: Estela, F.A.; López-Victoria, M.
Knowledge of the geographical distribution of the birds in the Colombian Caribbean is still meager. Coastal wetlands are among the less studied environments in the area and one of the most important for their high bird richness. Since 1998, inventories and monitoring of the bird populations of the lower part of the Sinú river have been made. Until July 2005, 296 bird species have been recorded for the area, 41 of which are new for this part of the Caribbean; in addition, new wintering localities were noted for eight migratory species. Breeding records were obtained for 98 species. Three species are threatened at some level and six have a restricted geographic distribution. New records for the area are explained in terms of the limited previous knowledge of...

Autores: Rodrigues,Marcos; Carrara,Lucas A.; Faria,Luciene P.; Gomes,Henrique B.
Foi conduzido um levantamento de espécies de aves do Vale do alto Rio Cipó durante o período de maio de 1998 a novembro de 2002. A região está totalmente inserida em uma das unidades de conservação mais importantes do sudeste do Brasil, o Parque Nacional da Serra do Cipó, em Minas Gerais. O método utilizado foi o de observação direta ao longo de 'transectos', captura com redes e identificação a partir do uso de vocalizações. A riqueza de espécies foi estimada usando-se o método de 'jackknife'. Foram registradas 226 espécies de aves pertencentes a 43 famílias. Isso corresponde cerca de 27% das 837 espécies já registradas para o bioma do Cerrado. Foram capturados 2.249 indivíduos num total de 4.486,82 horas-rede, onde foram amostradas 119 espécies...

Aves em oito áreas de Caatinga no Sul do Ceará e Oeste de Pernambuco, nordeste do Brasil: composição, riqueza e similaridade
Provedor de dados: 84
Autores: Olmos,Fábio; Silva,Weber Andrade de Girão e; Albano,Ciro Ginez.
Inventários rápidos realizados em diferentes pontos no sul do Ceará e oeste de Pernambuco em julho e setembro de 2004 encontraram um total de 209 espécies de aves. A maior riqueza foi de espécies características das várias formações da Caatinga (99 espécies), seguidas por espécies de áreas abertas ou generalistas (65) e aves aquáticas (45). Não foi encontrado um padrão que associasse a similaridade entre áreas a um padrão geográfico. As espécies numericamente dominantes tendem a ser pequenos insetívoros que se alimentam em meio à vegetação baixa e granívoros como Columbidae e Coryphospingus pileatus. Generalistas como Cyanocorax cyanopogon também foram dominantes em alguns pontos. As caatingas muito alteradas ao redor de lagoas temporárias de Petrolina...

Avian influenza control strategies in the United States of America
Provedor de dados: 26
Autores: Swayne, D.E.; Akey, B.L.
Prevention, control and eradication are three different goals or outcomes for dealing with avian influenza (AI) outbreaks in commercial poultry of the USA. These goals are achieved through various strategies developed using components of biosecurity (prevention or reduction in exposure), surveillance and diagnostics, elimination of infected poultry, decreasing host susceptibility to the virus (vaccination or host genetics) and education. However, the success of any developed strategy has depended on industry-government trust, co-operation and interaction. The preferred outcome for HPAI has been stamping out, for which the federal government has regulatory authority to declare an emergency and do immediate eradication of HPAI, and pay indemnities. For H5and...

Avian influenza viruses and influenza in humans
Provedor de dados: 26
Autores: Alexander, D.J.; Capua, I.; Brown, I.H.
Influenza-A viruses cause natural infections of humans, some other mammals and birds. Few of the 15 haemagglutinin and 9 neuraminidase subtype combinations have been isolated from mammals, but all subtypes have been isolated from birds. There are enormous pools of influenza-A viruses in wild birds, especially migratory waterfowl. In the 20th century there were 4 pandemics of influenza due to the emergence of antigenically different strains in humans: 1918 (H1N1), 1957 (H2N2), 1968 (H3N2) and 1977 (H1N1). The RNA of influenza-A viruses is segmented into 8 distinct genes and as a result genetic reassortment can occur in mixed infections with different viruses. The 1957 and 1968 pandemic viruses differed from the preceding viruses in humans by the...

Avian influenza viruses in Hong Kong: zoonotic considerations
Provedor de dados: 26
Autores: Shortridge, K.F.
Since the mid-1970s, Hong Kong has functioned as an influenza sentinel post for southern China, a region identified as a hypothetical epicentre for the emergence of pandemic influenza viruses. Nineteen ninety-seven marked the coming-of-age of animal-influenza studies with the recognition in Hong Kong of an incipient pandemic situation brought about by the infection of chicken and humans with an avian influenza H5N1 (H5N1/97) virus. Slaughter of all poultry across the Hong Kong SAR possibly averted a pandemic. Tracking down the source of the H5N1/97 virus to geese and quail and precursor avian H5N1, H9N2 and H6N1 viruses revealed that it was a triple reassortant. This provided a framework for influenza-pandemic preparedness at the baseline avian level,...

Avian mycoplasmosis update
Provedor de dados: 89
Autores: Nascimento,ER; Pereira,VLA; Nascimento,MGF; Barreto,ML.
Avian mycoplasmas occur in a variety of bird species. The most important mycoplasmas for chickens and turkeys are Mycoplasma gallisepticum (MG), M. synoviae (MS), and M. meleagridis. Besides, M. iowe (MI) is an emerging pathogen in turkeys, but of little concern for chickens. Mycoplasmas are bacteria that lack cell wall and belong to the class Mollicutes. Although they have been considered extracellular agents, scientists admit nowadays that some of them are obligatory intracellular microorganisms, whereas all other mycoplasmas are considered facultative intracellular organisms. Their pathogenic mechanism for disease include adherence to host target cells, mediation of apoptosis, innocent bystander damage to host cell due to intimate membrane contact,...

Axial incision: The key to understand submarine canyon evolution (in the western Gulf of Lion)
Provedor de dados: 5
Autores: Baztan, Juan; Berne, Serge; Olivet, Jean-louis; Rabineau, Marina; Aslanian, Daniel; Gaudin, Mathieu; Rehault, Jean Pierre; Canals, M.
A detailed morphological analysis of the outer shelf and continental slope of the Western Gulf of Lion is presented, based on swath bathymetry data together with sub-bottom profiles and high resolution seismic reflection profiles. These data reveal two main erosive features, of very different dimensions: the axial incision and the canyon's major valley. The height of axial incisions' flanks with respect to the canyon deepest point (the thalweg) ranges from 40 to 150 m. It creates a small axial erosive path within the canyon's major valley, which is typically bounded by flanks of more than 700 m in height. We interpret the axial incision observed in the sea floor as the imprint of turbidity currents that eroded the floor of canyons during phases of...

Az egyes tagállamokban érvényesülő súlyosabb adóterheket és az ezek által oko-zott verseny torzulásokat ellensúlyozhatja a hatósági tevékenység és/vagy a ked-vezőbb deviza/valutaárfolyam. A távlati célként megjelölt, teljesen egységes adózási környezetet egyelőre nem sikerült megteremteni.

Ez még inkább igaz a rendszerváltozás átalakulási, átmeneti gondjainak következményeivel vesződő hazai agrárgazdaságra és vidékre.  A fenntarthatóság és a vidékfejlesztés kibontakozása az Európai Unióban egymástól függetlenül párhuzamosan halad, s nem sokkal jobb a helyzet az ag-rárpolitikában és vidékpolitikában, miközben a fenntarthatóság középpontba ál-lítása, az agrár- és vidékfejlesztés tudatos összekapcsolása a kölcsönhatások és összefüggések előnyeinek kamatoztatása érdekében egyre sürgetőbb....

Az Európai Unió Közös Agrárpolitikára fordított kiadásainak szabálytalanul és jogtalanul kifizetett (4000 euró feletti) tételeit a tagállamok kötelesek jelenteni az EU Bizottságának.

Az ökomarketing az elmúlt évek alatt jelentősen megváltozott. Kezdetben a környezetbarát termékek marketingjét értették alatta, majd a vállalati stratégia elemévé vált.  Az utóbbi évek eredménye az „integratív” ökomarketing, amely a vállalat olyan magatartását jelenti, amikor a vállalat a vevők jólétének, egészségének biz-tosításán túl alkalmazottaival, a társadalommal szemben is felelősséget vállal. A „fenntartható marketing” a fenntartható fejlődési stratégiák vállalati meg-valósítására koncentrál. Egyes ágazatok, vállalatok környezeti érintettsége eltérő. A minősítéshez az adott tevékenység környezeti hatásainak mérésére, és annak ismeretére van szükség, hogy a jelentkező környezeti problémák megoldását ki vállalja föl, és milyen erős az...

Az öntözés egyik alapvető célja, hogy javítsa az egyre növekvő népesség élel-miszerrel való ellátását. A világon jelenleg a szántóterület 17%-át öntözik, vi-szont ez a felület adja az évenként betakarítható össztermés valamivel több mint 40%-át. Hazánkban a vízjogi engedéllyel rendelkező öntözésre berendezett terü-letünk 210 ezer hektár, ami a szántóterület közel 5%-a, de a ténylegesen öntözött terület évjárattól függően ennek kb. a fele. Az Európai Unióban átlagosan a szántóterület 13,5%-a tekinthető öntözöttnek. Az elkövetkező évek alapvető fejlesztési feladata a már meglévő öntözőrend-szerek felújítása és bővítése. A szántóföldi növények közül a kukorica, a napra-forgó, a cukorrépa és a burgonya öntözése indokolt. Az öntözött területek ará-nyának...

Babesiose cerebral em bovinos: 20 casos
Provedor de dados: 65
Autores: Rodrigues,Aline; Rech,Raquel Rubia; Barros,Ricardo Rocha de; Fighera,Rafael Almeida; Barros,Claudio Severo Lombardo de.
Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja.

Baby corn, green ear, and grain yield of corn cultivars
Provedor de dados: 75
Autores: Almeida,Itala Paula de C.; Silva,Paulo Sérgio L. e; Negreiros,Maria Z. de; Barbosa,Zenaide.
Most maize cultivars have been developed for grain production. Because superior cultivars may differ in their exploiting purposes, interest has been demonstrated for the evaluation of corn cultivars with regard to their baby corn, green ear, and grain yields production ability. In the present work ten corn cultivars (AG 405, AG 1051, AG 2060, AG 6690, AG 7575, AG 8080, DKB 333 B, DKB 435, DKB 350 and DKB 747) were evaluated in the yield of baby corn, green ears and dry grains. Two experiments were carried out in the same season, in neighboring areas and managed in a similar way, in Mossoró, Rio Grande do Norte State, Brazil, in a randomized blocks design with five replicates. Baby corn yield (178,571 plants ha-1) was evaluated in one of the experiments....

Bacillus subtilis as a tool for vaccine development: from antigen factories to delivery vectors
Provedor de dados: 42
Autores: Ferreira,Luís C.S.; Ferreira,Rita C.C.; Schumann,Wolfgang.
Bacillus subtilis and some of its close relatives have a long history of industrial and biotechnological applications. Search for antigen expression systems based on recombinant B. subtilis strains sounds attractive both by the extensive genetic knowledge and the lack of an outer membrane, which simplify the secretion and purification of heterologous proteins. More recently, genetically modified B. subtilis spores have been described as indestructible delivery vehicles for vaccine antigens. Nonetheless both production and delivery of antigens by B. subtilis strains face some inherent obstacles, as unstable gene expression and reduced immunogenicity that, otherwise, can be overcome by already available gene technology approaches. In the present review we...

Bacillus thuringiensis resistance management: experiences from the USA
Provedor de dados: 26
Autores: Hurley, T.M.
The role of the US Environmental Protection Agency (EPA) in the regulation of Bt crops is discussed with an emphasis on resistance management. A stochastic bioeconomic simulation model is presented to show how previous analyses of insectresistance management (IRM) policy can be improved by including the effect of farmer adoption and compliance behaviour on the evolution of Bt resistance. An example shows that the traditional assumptions of full adoption and compliance overestimate the risk of Bt resistance. However, since adoption and compliance behaviour have countervailing effects on the evolution of resistance, the result should be interpreted with caution until better information is available on farmer adoption and compliance behaviour

Bacteria and phytoplankton production rates in eight river stretches of the middle Rio Doce hidrographic basin (southeast Brazil)
Provedor de dados: 52
Autores: Petrucio,Mauricio Mello; Barbosa,Francisco Antônio R.; Thomaz,Sidinei Magela.
Measurements of bacterial secondary production (BSP), together with primary phytoplanktonic production (PPP) were conducted during dry and rainy seasons, in eight rivers of different orders submitted to different degrees of human impacts (different trophic degree). We aimed to determine and compare the importance of BSP and PPP in carbon fixation in these different lotic ecosystems. Our results showed that the Ipanema River was the most modified system by anthropogenic effluents inputs. These inputs altered the trophic degree and BSP rates of these streams and rivers.

Bacterial exopolysaccharides from extreme marine environments with special consideration of the southern ocean, sea ice, and deep-sea hydrothermal vents: A review
Provedor de dados: 5
Autores: Mancuso Nichols, Carol; Guezennec, Jean; Bowman, John.
Exopolysaccharides (EPSs) are high molecular weight carbohydrate polymers that make up a substantial component of the extracellular polymers surrounding most microbial cells in the marine environment. EPSs constitute a large fraction of the reduced carbon reservoir in the ocean and enhance the survival of marine bacteria by influencing the physicochemical environment around the bacterial cell. Microbial EPSs are abundant in the Antarctic marine environment, for example, in sea ice and ocean particles, where they may assist microbial communities to endure extremes of temperature, salinity, and nutrient availability. The microbial biodiversity of Antarctic ecosystems is relatively unexplored. Deep-sea hydrothermal vent environments are characterized by high...

Provedor de dados: 52
Autores: Souza,Evandro Leite de; Silva,Clemilson Antonio da; Sousa,Cristina Paiva de.
Bacteriocins are proteic molecules synthesized for various lineages of Gram-positive and Gram-negative bacteria when exposed to stressful conditions. Bacteriocins have been characterized as molecules of high antimicrobial property even at low concentrations, provoking the microbial survival inhibition by antibiosis. These substances have their synthesis mediated for genetic mechanisms and develop their lethal action on the microbial cell by multiples mechanisms that can act of isolated or concomitant way culminating with microbial cell killing. This molecules class presents characteristic of stability to heat, low pH, refrigeration and freezing, and resistance to weak organics solvents, salts and enzymes. On the other hand, they are very sensitive to...

Autores: Mendonça de Araujo,K.; Mourão,P.A.S.; Leta,J.
We analyzed the trends of scientific output of the University Hospital, Federal University of Rio de Janeiro. A total of 1420 publications were classified according to pattern and visibility. Most were non-research publications with domestic visibility. With time, there was a tendency to shift from non-research (or education-oriented) publications with domestic visibility to research publications with international visibility. This change may reflect new academic attitudes within the institution concerning the objectives of the hospital and the establishment of scientific research activities. The emphasis of this University Hospital had been on the training of new physicians. However, more recently, the production of new knowledge has been incorporated as...

Balancing fertilization strategy with crop requirements in organic greenhouse cultivation of sweet pepper
Provedor de dados: 21
Autores: Cuijpers, W.J.M.; Voogt, W.; Koopmans, C.J.
An on-farm field trial was set up in an organic greenhouse in order to balance the N-uptake by a sweet pepper crop and the mineralization of the organic fertilizers was applied. The effects of six fertilizer treatments were compared regarding yield, nutrient availability and mineral balance. Application of high levels of compost turned out to be favourable in order to reduce surplusses of available-N on the short term. On the long term, such high levels of compost are unfavourable as a high pool of mineralizable-N in the soil organic matter restricts the possiblities for precise fertilization adapted to plant uptake. Application of lower levels of farm yard manure in combination with additional fertilization with feathermeal turned out to be a good...

Autores: Teixeira,Carlos A.; Lacerda Filho,Adílio F. de; Pereira,Sidney; Souza,Luís H. de; Russo,José R.
É importante destacar que o consumo de energia envolvido ao longo do cultivo de tomate depende de fatores que tornam complexa a sua estimativa. Neste trabalho considerou-se, basicamente, a energia contida na mão-de-obra, no combustível necessário à produção e aplicação de fertilizantes, inseticidas, fungicidas e na produção e operação de tratores e equipamentos, durante o desenvolvimento da cultura. A metodologia utilizada para se obter o balanço energético da cultura foi proposta por Serra et al. (1979). O consumo de energia total observado foi igual a 2.661.945 MJ ha-1, enquanto a planta do tomateiro produziu 26.013 MJ ha-1. A energia solar global média disponível foi igual a 2.515.303 MJ ha-1 e a produtividade média de tomate foi igual a 23,94 t ha-1.

Banco de sementes de plantas daninhas e herbicidas como fator de seleção
Provedor de dados: 53
Autores: Monquero,Patrícia Andréa; Christoffoleti,Pedro Jacob.
O banco de sementes representa um papel ecológico importante no suprimento de novos indivíduos para as comunidades vegetais. Nos agroecossistemas, o banco de sementes, normalmente constitui um sério problema à atividade agrícola, pois garante infestações de plantas daninhas por longo tempo, mesmo quando é impedida a entrada de novas sementes na área. O solo agrícola é um grande depósito de sementes, entretanto, a composição florística de um solo, em determinado momento, não representa o potencial real de infestação, já que certas espécies necessitam de condições especiais para a quebra de dormência e posterior germinação. Além disso, as sementes que estão na superfície do solo também estão sujeitas à predação, parasitismo e dispersão. Os diferentes...

Banking Sector Reform and Financial Regulation: It's Effects on Access to Financial Services by Low Income Households in Zambia
Provedor de dados: 31
Autores: Chiumya,   Chiara.
The change in government in 1991 brought about radical economic reform, from state control to an economy led by private sector development. The reforms included decentralisation, privatisation and liberalisation of the financial sector. Liberalisation initially led to the proliferation of financial institutions in the financial sector. However, it also led to a number of bank failures, resulting in the closure of nine commercial banks since 1995. Access to financial services by the majority of Zambian's was further constrained by the closure of unprofitable rural branches by commercial banks, the raising of minimum account balances and the introduction of bank charges, as well as the closure of a number of Government owned financial institutions...

Bargaining Coalitions in the Agricultural Negotiations of the Doha Round: Similarity of Interests or Strategic Choices? An Empirical Assessment
Provedor de dados: 31
Autores: Costantini,   Valeria; Crescenzi,   Riccardo; de Filippis,   Fabrizio; Salvatici,   Luca.
The paper aims at understanding the structural features of the bargaining coalitions in the Doha Round of the WTO. We provide an empirical assessment of the preferences of each negotiating actor looking at general economics indicators, development levels, structure of the agricultural sectors, and trade policies for agricultural products. Bargaining coalitions are analyzed by grouping countries through a cluster analysis procedure. The clusters are compared with existing coalitions, in order to assess their degree of internal homogeneity as well as their common interests. Such a comparison allows the detection of possible “defectors”, i.e. countries that according to their economic conditions and policies seem to be relatively less committed to the...

Autores: Cardoso,L.M.; Pedrosa,M.L.; Silva,M.E.; Moraes,M.F.D.; Colombari,E.; Chianca-Jr.,D.A.
Our hypothesis is that iron accumulated in tissue, rather than in serum, may compromise cardiovascular control. Male Fischer 344 rats weighing 180 to 220 g were divided into 2 groups. In the serum iron overload group (SIO, N = 12), 20 mg elemental iron was injected ip daily for 7 days. In the tissue iron overload group (TIO, N = 19), a smaller amount of elemental iron was injected (10 mg, daily) for 5 days followed by a resting period of 7 days. Reflex heart rate responses were elicited by iv injections of either phenylephrine (0.5 to 5.0 µg/kg) or sodium nitroprusside (1.0 to 10.0 µg/kg). Baroreflex curves were determined and fitted to sigmoidal equations and the baroreflex gain coefficient was evaluated. To evaluate the role of other than a direct effect...

Baryancistrus demantoides and Hemiancistrus subviridis, two new uniquely colored species of catfishes from Venezuela (Siluriformes: Loricariidae)
Provedor de dados: 83
Autores: Werneke,David C.; Sabaj,Mark H.; Lujan,Nathan K.; Armbruster,Jonathan W.
Baryancistrus demantoides and Hemiancistrus subviridis are two new species of loricariids from southern Venezuela with an olive ground coloration and white to cream-colored or golden-yellow spots. Baryancistrus demantoides is known only from the upper río Orinoco drainage while H. subviridis is also known from the río Casiquiare drainage. In addition to its coloration, B. demantoides can be distinguished from all other ancistrins by having the dorsal and adipose fins connected by an expanded posterior section of the dorsal-fin membrane, golden-yellow spots confined to the anterior portion of the body, and greater than 30 teeth per jaw ramus. Hemiancistrus subviridis can be separated from all other ancistrins by coloration, lacking a connection between the...

Bases biologiques de la production de deux Mollusques d'intérêt économique: reproduction chez Megathura crenulata, reproduction et développement chez Crassostrea gigas
Provedor de dados: 5
Autores: Cannuel, Rozenn.
The reproductive cycle of Megathura crenulata was documented and quantification of oocyte lipid reserves with lipo-specific stains was explored in both this species and in Crassostrea gigas.  The necessity of providing food to female broodstock C. gigas in spring was re-evaluated, because subsequent larval and post-larval rearing performance was not affected by broodstock starvation during conditioning.  Developmental study of the organs responsible of particle processing in C. gigas allowed the identification of critical stages related to the ontogenesis of each organ, as well as a better understanding of the evolution of these organs, highly-modified in the Ostreidae. Ciliary type identification and mucocyte mapping from post-larval to adult stage showed...

Basidiome development of Xeromphalina campanella (Tricholomatales, Basidiomycetes)
Provedor de dados: 16
Autores: Clémençon, H.
The agaricoid Hymenomycete Xeromphalina campanella is exocarpic, apertopileate and amphiblemate. Metablemas develop separately on the pileus and on the stipe, but they do not form any kind of veil. The pileoblema becomes a gelatinous pileipellis, and the cauloblema forms a hairy coating on the lower part of the stipe of the mature basidiomes. The hymenophoral trama is bidirectional in the gill rudiments, but becomes more physalo-irregular at maturity and contains many narrow hyphae with smooth or incrusted walls. The context of the stipe resembles a sarcodimitic structure, but the thin-walled inflated cells are rarely fusiform, although they are frequently gradually narrowed at one end. Between the physalohyphae, narrow, incrusted hyphae and ramified...

Fresh basil (Ocimum basilicum L.) is used in food, phytotherapic industry, and in traditional therapeutic, due to its essential oil content and composition. Nevertheless basil can not be kept for long periods after harvest and its quality can be reduced. This work aimed to assess the influence of the season and harvest time in the postharvest conservation of basil stored for different periods. Basil was harvested at 8 am and 4 pm both in August/1999 and January/2000. Cuttings were conditioned in PVC packages and stored for 3, 6, and 9 days. During storage, chlorophyll content, essential oil content and composition were determined as well as microbiological analyses were carried out. Harvest season and the days of storage influenced the final content of...

Bathroom practices today
Provedor de dados: 21
Autores: Quitzau, Maj-Britt.
The present study aims at understanding some of the dynamics of social change that are underlying the present waves of interest related to the bathroom by taking a practice-oriented hold of ‘what is going on’ with the way bathrooms are used and arranged today in a specific Danish context. Through this approach, typical bathroom practices are laid out, hereby pointing out important contemporary aspects of the way bathrooms are used and arranged. Following this, dynamics connected to the shaping process of these practices are studied by analysing how practitioners and producers of bathrooms form part of this shaping process and how this is related to the overall development of the bathroom.

Bathymetric trends of northeastern Brazilian snappers (Pisces, Lutjanidae): implications for the reef fishery dynamic
Provedor de dados: 52
Autores: Frédou,Thierry; Ferreira,Beatrice Padovani.
The investigation of bathymetric distribution of five snappers caught along the Brazilian Northeastern coast by artisanal fleets through the analysis of the catch composition and relative abundance (CPUE) showed that, on the overall, fished mean size increased along depth and that particular species dominated the catch according to the depth strata. Mutton snapper, L. analis, yellowtail snapper, L. chrysurus, and dog snapper, L. jocu were mainly caught at intermediate depth (20-80m) whereas lane snapper, L. synagris, and silk snapper, L. vivanus, inhabit respectively shallow (&lt;20m) and deep (&gt;80 m) waters. Each fleet category exploited preferentially a particular combination of species and their size range. The fleet dynamic of the Northeast Brazil...

Bayesian Analysis of Consumer Choices with Taste, Context, Reference Point and Individual Scale Effects
Provedor de dados: 31
Autores: Hu,   Wuyang; Adamowicz,   Wiktor L.; Veeman,   Michele M.
This paper adopts an approach based on the concepts of random utility maximization and builds on the general theoretical framework of Lancaster and on the conceptual and econometric innovations of McFadden.  Recent research in this area explores models that account for context effects, as well as methods for characterizing heterogeneity, response variability and decision strategy selection by consumers.  This makes it possible to construct much richer empirical models of individual consumer behavior.  A Bayesian approach provides a useful way to estimate and interpret models that are difficult to accomplish by conventional maximization/minimization algorithms.  The application reported in the paper involves analysis of reference dependence and product...

Bayesian Inferences on Fourier Flexible Functional Form in Agricultural Production
Provedor de dados: 31
Autores: Featherstone,   Allen M.; Cader,   Hanas A.
Flexible functional forms are used to examine the characteristics of production technologies.  The Fourier functional form is capable of approximating any function globally, with the specified expansion. Unfortunately the exact form of the expansion is not known. The regularity conditions are likely to be violated without the exact form of expansion. In this paper we use a Bayesian approach to impose regularity conditions locally on a Fourier flexible functional from using agricultural production data.  Monotonicity, concavity, convexity and elasticities are compared.

Beach ridges, foredunes or transgressive dunefields? Definitions and an examination of the Torres to Tramandaí barrier system, Southern Brazil
Provedor de dados: 42

Many prograded barriers and some dunefields in theworld have been termed 'beach ridge' plains, but the actual genesis of the 'ridges' is often unknown. Use of the terms, berms, beach ridges and foredunes is also confusing in the literature because their definitions are highly variable and are commonly used interchangeably. Thus, the formation and definition of sand berms, beach ridges and foredunes is briefly reviewed. Beach ridges are re-defined as entirely wave formed deposits which are most commonly formed during high wave conditions and/or elevated water levels (e.g. storm surges). Foredunes are formed by aeolian sand deposition in vegetation on the backshore. Some dunefields in Brazil have been called beach ridge plains when they are, in fact,...

Autores: Pekrun, Carola; Claupein, Wilhelm.
In a field experiment at the Experimental Station for Organic Farming Kleinhohenheim the effect of stubble tillage has been assessed over a period of five years. Perennial weeds were effectively controlled by stubble tillage. Annual weeds were not affected when considering the above ground populations. Shallow ploughing revealed no better effect than the other implements tested. The results show that stubble tillage is very important for the control of perennial weeds in Organic Farming. A renaissance of the shallow plough appears not to be necessary.

Organic farming has rapidly grown in Switzerland in the past years. It is now well established in agriculture and accepted by consumers. However, recent developments show declining growth rates. This raises the question of the future that can be expected for organic farming in Switzerland.  Future trends and potentials of organic farming in Switzerland made subject of two diploma theses in which prospects of the dairy and livestock sector and the fruit and vegetable sector were analysed. With a linear optimization model (farm level), taking into account probable future conditions, the development of supply was estimated. The future evolution of consumer demand was assessed by the means of a qualitative analysis. The analysis of supply and demand showed...

One consequence of the BSE-crisis is, that animal residue derived N-fertilisers used in organic horticulture are to be replaced. As an alternative plant derived N-fertilisers have been investigated. In an incubation experiment these fertilisers mineralised 40 to 60  % of the total N applied. Net N-mineralisation in the incubation experiment as well as plant N-utilisation in a pot experiment were closely related to the N-content of the fertilisers. Fertilisers increased the N-uptake of plants in any soil. Neither texture nor the content of Corg explained the observed differences in fertiliser use efficiency .

Beeinflussung der generativen Vermehrung von Rumex obtusifolius durch produktionstechnische Maßnahmen
Provedor de dados: 21
Autores: Pekrun, Carola; Hofrichter, Veit; Link, Johanna; Thymian, Frank; Thumm, Ulrich; Claupein, Wilhelm.
Rumex obtusifolius produces a large number of long living seeds. Therefore, all means to reduce seed production or establishment of seedlings from seeds are impor-tant. The data of this paper show that in grassland a high soil seed bank not necessar-ily leads to a high infestation with dock. There are options to interfere seed production and establishment of seedlings. The cutting regime may have an impact on seed production. Establishment of seedlings can be minimized by avoiding gaps in the vegetation canopy.

Provedor de dados: 31
Autores: Balagtas,   Joseph Valdes; Kim,   Sounghun.
We develop a multi-market equilibrium displacement model that allows for demand linkages (substitutes or complements) across downstream product markets, and supply linkages through the common use of a raw commodity as the key input.  Applying the model to the dairy sector, we find that the effectiveness of producer-funded advertising, and thus optimal advertising intensities, depends on the demand relationships across dairy product markets (cross-price and cross-advertising elasticities), as well as the re-allocation of raw milk towards the advertised market.  We argue that the previous literature, which ignores the horizontal linkages highlighted here, tends to overstate the effectiveness of generic commodity promotion for dairy, and thus results in too...

Behavior and performance of broiler strains reared under semi-intensive system with shaded areas
Provedor de dados: 89
Autores: Barbosa Filho,JAD; Silva,MAN; Silva,IJO; Coelho,AAD; Savino,VJM.
The matter of animal welfare has led to studies in order to evaluate alternative rearing systems for livestock in order to improve well-being. The semi-intensive system is an alternative method of rearing broilers in which the birds are kept in a poultry house and have free access to a pasture area during the day. It is known that ambient conditions may directly affect the behavior of birds reared in the semi-intensive system. Therefore, this research evaluated the behavior of four broiler strains reared under a semi-intensive system with a shaded area (provided by a black plastic screen - 50%) and the bioclimatic characteristics of this environment when compared with the non-shaded pasture. Thirty-five birds were reared in pens with 4.5 m² and 35 m² of...

Behavioral Incentives, Equilibrium Endemic Disease, and Health Management Policy for Farmed Animals
Provedor de dados: 31
Autores: Hennessy,   David A.
We develop a dynamic capital valuation model in which each farm can take an action with farm-varying cost to increase the probability of not contracting a disease. In the presence of infection externalities, circumstances are identified under which multiple equilibria exist and where the one involving the most extensive set of action takers is socially optimal. It is suggested that costly capital markets are one factor in determining the extent of endemic disease in a region. The introduction of frictions, such as dealing with a cumbersome veterinary public health bureaucracy, can enhance social welfare by encouraging precautionary biosecurity actions. Some technical innovations can reduce social welfare. The model is also extended to study a voluntary...

Behaviour of pre-parturient sows housed in intensive outdoor or indoor systems
Provedor de dados: 86
Autores: Hötzel,Maria José; Machado Filho,Luiz Carlos Pinheiro; Dalla Costa,Osmar Antônio.
This work compared the behaviour of pre-parturient sows housed in intensive confined and outdoor systems, during the morning and afternoon prior to delivery. Eight sows were kept individually in farrowing crates or in paddocks with access to fresh pasture from 8 to 10 days before expected parturition. All outdoor sows built a nest within 24 hours before farrowing. On the morning and afternoon before farrowing they spent 6.5% of the time collecting grass and 7.5% of the time organizing the nest. Outdoor sows were observed more often than confined sows rooting (4.60% vs. 0.25%), feeding (10.2% vs. 3.0%), standing (51% vs. 13%) and walking (8% vs. 0%). Indoor sows redirected the nesting behaviour to other behaviours like attempts to dig the ground, nosing,...

Autores: Mendonça,Luciana Baza; Anjos,Luiz dos.
A assembléia de flores visitadas por beija-flores e a partilha de recursos entre estas aves foram estudadas em uma área urbana do sul do Brasil. Vinte e duas espécies de plantas, em sua maioria exóticas e/ou não-ornitófilas, receberam visitas dos beija-flores. As espécies de beija-flores registradas apresentaram diferentes combinações de características morfológicas (massa, comprimento do bico, comprimento da asa e relação bico/asa), que refletiram no conjunto de flores exploradas e no papel comunitário desempenhado por cada espécie. De um modo geral, beija-flores com nichos tróficos mais amplos foram também os mais freqüentes na área de estudo, indicando que o ambiente urbano pode ser mais favorável às espécies generalistas.

Beisaat von Zwischenfrüchten als Möglichkeit zur Reduzierung der N-Auswaschung in Wintergetreide?
Provedor de dados: 21
Autores: Loges, Dr. Ralf; Mauscherning, Inken; Taube, Prof. Dr. Friedhelm.
In a field experiment the potential of mixtures of winter cereals and catch crops to reduce nitrate leaching was investigated. Pure winter wheat showed the highest N-losses (56 kg N ha-1). Compared to a control without a catch crop, winter rye and oilseed radish grown in pure stand or in mixture with a winter cereal reduced nitrate-leaching by 30 to 80 %. However, common vetch had a significant lower potential compared to the tested non-legume catch crops. Further investigations are needed to optimize the system with special regards to the concurrence between cereal and catch crop in autumn and in early spring.

Bekämpfungsstrategien für pflanzenparasitäre Nematoden im ökologischen Landbau
Provedor de dados: 21
Autores: Hallmann, Johannes; Klinger, Sonja; Rau, Florian.
Plant parasitic nematodes are an increasing threat to organic farming in Germany. Especially taxa with broad host spectra and high multiplication rates such as Meloidogyne hapla and Pratylenchus spp. can cause severe damage up to total loss of the crop. The control of these nematodes is extremely difficult. Resistant cultivars are not available and only few non-host crops are known. Weed control is another important issue as most weeds are excellent hosts. In 2003 and 2004 two on-farm trials aimed at controlling M. hapla and Pratylenchus spp. were conducted in Niedersachsen, Germany. Results from these trials can be summarized as follows. For M. hapla, best control was achieved with black fallow and maize in combination with weed control. Fodder radish...

Below-harvest biomass and N2 fixation in grass-clover at different cutting frequencies
Provedor de dados: 21
Autores: Vinther, F.P.
The below-harvest nitrogen accumulating in stubble, stolons and roots is an important com-ponent in the N balance and the potential N losses in grass-clover cropping systems. The effects of cutting frequency on the total dry matter, total nitrogen and N2 fixation, including contributions from below-harvest production, were studied. In a greenhouse experiment with red and white clover plants, cutting reduced the above-ground dry matter production by 56-62% and the below-ground by 68-73%, compared to uncut plants. Similarly, in a two-year field study with ryegrass-white clover, simulated grazing reduced the harvested dry matter production by 6-19% and the below-harvest, i.e., stubble, stolons and roots, by 20-35% com-pared to normally mowed grass-clover....

Kale Brassica oleracea var. acephala is attacked by whitefly Bemisia tabaci, aphid Brevicoryne brassicae and Thrips tabaci. One of the main reasons for extensive insecticide application is the lack of information about factors that control insect population. The objectives of this study were to investigate the relationships between predators and parasitoids, organic compound leaves, levels of leaf nitrogen and potassium, total rainfall, relative humidity, sunlight and median temperature on the abundance of whitefly, aphid, and thrips in kale genotype "Talo Roxo". The beating tray method, direct counting and magnifying lens were used to estimate the number of these pests, predators and parasitoids. Median temperature, sunlight and relative humidity...

Provedor de dados: 58
Autores: Otenio,Marcelo Henrique; Silva,Maria Teresa Lopes da; Marques,Maria Luiza Oliveira; Roseiro,José Carlos; Bidoia,Ederio Dino.
A minimal liquid medium containing benzene (B), toluene (T) and xylene (X) and mixtures thereof, was used to evaluate degradation activity of Pseudomonas putida CCMI 852 containing a TOL plasmid. Experiments were developed with B, T and X (100 mg L-1), with mixtures of BT, BX, and TX (50 + 50 mg L-1 each) and BTX (33.3 + 33.3 + 33.3 mg L-1 each), added to 500 mL of medium. After 18 to 24 hours, the inoculum was added and solvent disappearance was determined after 24 to 25 hours by GC. Results showed that P. putida CCMI 852 was able to metabolize T and X, but B was not metabolized. In a BTX mixture, B was not metabolized and T and X degradation rate decreased 50%.

Bernoulli Regression Models: Re-examining Statistical Models with Binary Dependent Variables
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Spanos,   Aris.
The classical approach for specifying statistical models with binary dependent variables in econometrics using latent variables or threshold models can leave the model misspecified, resulting in biased and inconsistent estimates as well as erroneous inferences. Furthermore, methods for trying to alleviate such problems, such as univariate generalized linear models, have not provided an adequate alternative for ensuring the statistical adequacy of such models. The purpose of this paper is to re-examine the underlying probabilistic foundations of statistical models with binary dependent variables using the probabilistic reduction approach to provide an alternative approach for model specification. This re-examination leads to the development of the Bernoulli...

The present paper analyzes the role of discourse in conflicts concerning nature conservation in tropical countries. We focus on the contested question as to whether and to which extent local communities should be allowed to live and use resources inside protected areas. Applying the concepts of belief-systems, story-lines and discourse coalitions, we analyze two empirical case studies dealing with this conflict: The first case study is concerned with a policy process at the national level that aimed at passing a community forestry law in Thailand to make the establishment of community forests in protected areas possible. The second case study deals with the proposed resettlement of a village from the Lore Lindu National Park in Sulawesi, Indonesia. In both...

BEYOND GATEWAY CITIES: ECONOMIC RESTRUCTURING AND POVERTY AMONG MEXICAN IMMIGRANT FAMILIES AND CHILDREN

Autores: Crowley,   Martha L.; Lichter,   Daniel T.; Qian,   Zhenchao.
Our main objective is to better understand how new residential patterns have reshaped patterns of poverty among America's growing Mexican-origin population. We use data from the Integrated Public Use Microdata Samples (IPUMS) to document recent changes in poverty rates among native-born and foreign-born Mexicans living in the Southwest and in new regions where many Mexican families have resettled. Our analysis focuses on how changing patterns of employment (e.g., in construction and food processing industries) have altered the risk of poverty among Mexican families and children.

Beyond Goods and Services: Competition Policy, Investment, Mutual Recognition, Movement of Persons, and Broader Cooperation Provisions of Recent FTAs Involving ASEAN Countries
Provedor de dados: 31
Autores: Dayaratna,   Banda O.G.; Whalley,   John.
We discuss recent bilateral, regional, and country trade, partnership, and economic agreements involving both ASEAN as a single entity and individual ASEAN countries (Singapore, Thailand, Malaysia) focusing on their reach beyond conventional trade in goods and services issues. These agreements are recent, but they are numerous and more are under negotiation. We separately synthesize and evaluate provisions in five areas; competition policy, investment, mutual recognition, movement of persons, and broader cooperation. What emerges is of a picture of ill defined general commitments and precise undertaking, which vary from element to element and country pair to country pair, but there can be little doubt as to the presence of substance, which in turn,...

Beyond Optimal Linear Tax Mechanisms: An Experimental Examination of Damage-Based Ambient Taxes for Nonpoint Polluters
Provedor de dados: 31
Autores: Suter,   Jordan F.; Poe,   Gregory L.; Vossler,   Christian A.
The regulation of nonpoint source water pollution from agriculture is a complex problem characterized by a multiplicity of polluters, informational asymmetries, complex fate and transport processes, and stochastic environmental factors.  Taken together, these characteristics make regulatory policy based on individual firm emissions prohibitively costly.  To circumvent this issue, economists, beginning with the seminal work of Segerson (1988), have devised economic incentive instruments that assign liabilities based on deviations between the observed ambient water quality level and a specified pollution threshold (Xepapadeas 1991; Horan, Shortle and Abler 1998, 2002; Hansen 1998, 2002).     In the special case of a linear damage function, the regulator can...

Beyond Rural: Urban: Keeping Up With Changing Realities
Provedor de dados: 31
Autores: Garrett,   James L.
Policies built on presumptions of separateness or on traditional notions of urban and rural livelihoods diminish the possibilities for economic growth and poverty reduction. More effective policies will take the diversity of livelihoods along the continuum into account and also appreciate the differences among urban and rural areas and the links between them. Focusing on the connections between urban and rural areas can help to reframe our understanding of development in these areas. We can see that rural and urban lives and livelihood strategies span rural and urban geographies in integrated and interdependent ways. With better understanding of the current reality of urban and rural areas and the connections between them, policies will better reflect the...

Beyond selection
Provedor de dados: 97
Autores: VARGAS,ALEXANDER O.
It has been argued that the study of natural selection and quantitative genetics should have a central role in evolutionary thinking and undergraduate teaching in Chile. Extensive operational use of the concept of natural selection may seem consistent with this argument. However, advances of evolutionary knowledge in independent fields such as phylogenetic analysis, developmental evolution, and paleontology cannot be ignored. I argue here that the role of natural selection in contemporary evolutionary biology can be compared to that of Newtonian mechanics in contemporary physics: it can describe a given domain of observations, but it is insufficient to handle the different sources of evolutionary knowledge. Overemphasis on natural selection as the...

Beyond Water-Quality Regulations for CAFOs? Manure Management Costs to Meet Air-Quality Objectives
Provedor de dados: 31
Autores: Aillery,   Marcel P.; Gollehon,   Noel R.
Federal policy on manure management has focused on water-quality protection.  However, animal agriculture is an important source of ammonia-nitrogen and other air emissions, increasing attention on air-quality concerns.  Policies to address air emissions would influence both the costs of meeting water-quality objectives and environmental tradeoffs.  We consider hypothetical policies at a regional level.

Bi-Directional Links Between Population Growth and the Environment: Evidence From India
Provedor de dados: 31
Autores: Bhattacharya,   Haimanti; Innes,   Robert.
This paper presents an empirical study of population growth and environmental change using cross-sectional district-level data from South, Central and West India.  Environmental change is measured using a satellite-based "greenness" index.  Unlike prior work, the analysis treats population and environmental change as jointly determined, distinguishes between rural and urban populations, and identifies distinct roles of fertility and migration.  Among key findings are that population and "greenness" are jointly endogenous; increased rural fertility leads to environmental decline, which in turn prompts increased fertility; environmental scarcity spurs out-migration and environmental improvement; and increased urban fertility may lead to increased...

Created in 1986, the REPAMO network (Network of mollusc pathology), is a national zoosanitary surveillance network of shellfish health status along the French coasts. Its activities are in keeping with two European Directives, 91 /67/EEC and 95/70/EC and are a patt of the institutional tasks ofIfremer. The aims of the network are to prevent the introduction and spread of exotic pathogens and to survey the evolution of notifiable pathogens already present in France. The network focused on the survey of listed diseases (bonamiosis and marteiliosis of flat oyster) in two areas under agreement process (Banc de Granville and zone X). In 2004, no sample couId be analysed to these two areas because of the difficulty to obtain flat oysters (sparse oyster beds,...

Hybrid varieties are increasingly and widely used in organic farming, although there has  never been a conscious decision to do so. This is especially true for vegetables and maize. For bread cereals, especially rye, the decision can still be taken in Switzerland. Organic rye is grown on only 250 ha, about 20% of which are hybrid varieties. About 60% of the total organic demand is imported.

Bioactive amines in Brazilian wines: types, levels and correlation with physico-chemical parameters
Provedor de dados: 52
Autores: Souza,Solange C.; Theodoro,Karine H.; Souza,Élson R.; Motta,Silvana da; Glória,Maria Beatriz Abreu.
The levels of ten bioactive amines and the physico-chemical characteristics of Cabernet Sauvignon, Cabernet Franc and Merlot wines from Bento Gonçalves, RS, Brazil, vintage of 1999 were investigated. The physico-chemical characteristics varied significantly: pH from 3.80 to 4.07, total acidity from 67.7 to 85.3 meq/L, alcohol content from 11.45 to 12.46 mL/100 mL and total SO2 from 9.6 to 102 mg/L. Six amines were detected in every sample - spermidine, putrescine, histamine, tyramine, serotonine and phenylethylamine. Total amine levels ranged from 2.03 to 7.60 mg/L. Putrescine was the prevalent amine, contributing with 20 to 66% of total levels. The amine profile and total levels were affected to a greater extent by vinification practices compared to grape...

Many compounds affect the bioavailability of radiobiocomplexes as radiopharmaceuticals. Ginkgo Biloba extract (EGb) has several effects. The influence of an EGb on the bioavailability of the radiobiocomplex sodium pertechnetate (Na99mTcO4) and on the morphometry of the organs was evaluated. Rats were treated with EGb and Na99mTcO4 was injected. The animals were sacrificed; the radioactivity in the organs was counted. The results showed that EGb altered the Na99mTcO4 bioavailability in the kidneys, liver and duodenum. Morphometric analysis of the organs showed significant alterations (P&lt;0.05), probably caused by metabolites generated by EGb and capable of altering the bioavailability of the Na99mTcO4.

There has been considerable interest focused on the further development and expansion of a domestic bio-fuels industry. While most early attention from the commercial sector focused on ethanol, interest is now growing in the area of biodiesel production. Reasons for growing interest in biodiesel include its potential for reducing noxious emissions, potential contributions to rural economic development, as an additional demand center for agricultural commodities, and as a way to reduce reliance on foreign oil. Despite interest over the past decade or so, however, experience with biodiesel production in the US is limited.

This paper examines the use the use of economic incentives for knowledge generation through biodiscovery, in the particular case of the use of a highly valuable biogenetic resource stock from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from institutional and ecological economics. Two important conclusions come out of this analysis. First, it highlights the necessity to go beyond standard market approaches to economic valuation in order to address the issues of future possibilities of use and innovation and the integration of the different stages in the process of value creation. Second, it shows the necessity of developing alternatives to the current intellectual...

The oral administration of proteic antigens, like ovalbumin, may result in the induction of oral tolerance or immunization. The aim of this work was to label a protein antigen with 99mTechnetium, encapsulate it in liposomes and investigate its absorption and tissue distribution after oral administration in mice. Ovalbumin was labeled with 99mTechnetium and encapsulated in small unilamellar vesicles. 99mTc-OVA encapsulated or not in liposomes was administrated to mice that were sacrificed after different times. The radioactivity was measured in various organs of the animals. Differences concerning the biodistribution of 99mTc-OVA were noticed. The technique may represent alternatives for the induction of immunization or oral tolerance.

The use of radiotracers allows the understanding of the bioavailability process, biodistribution, and kinetics of any molecule labelled with an isotope, which does not alter the molecule's biological properties. In this work, technetium-99m and iodine-125 were chosen as radiotracers for biodistribution studies in mice using bee (Apis mellifera) venom and a toxin (PnTX2-6) from the Brazilian "armed" spider (Phoneutria nigriventer) venom. Incorporated radioactivity was measured in the blood, brain, heart, lung, liver, kidney, adrenal gland, spleen, stomach, testicle, intestine, muscle, and thyroid gland. Results provided the blood kinetic parameter, and different organs distribution rates.

Biodiversity and economic incentives in agriculture : integrating bird fauna values into decision-making
Provedor de dados: 21
Autores: Miettinen, Antti; Huhtala, Anni.
Our optimal control model identifies economic reasons as to why several farmland bird populations have dramatically declined in modern agricultural landscapes. By integrating bird fauna values into decision-making on cereal crop choice, herbicide use and hunting bag size, we derive those economic instruments needed for enhancing biodiversity on farmland and reversing the decline of grey partridge (Perdix perdix) populations. Based on the Finnish data available, we illustrate how the optimal acreage subsidy for organically-grown rye areas, the herbicide tax rate and the grey partridge hunting licence fee could be estimated in monetary terms. The procedure to derive and value the first-best policy instruments is applicable for various components of...

Biodiversity and Sustainable Management of a Tropical Wetland Lake Ecosystem: a case study of Lake Kanyaboli, Kenya
Provedor de dados: 20
Autores: Abila, R.
Lake Kanyaboli and the surrounding Yala Swamp wetland have been recognized as an important biodiversity hotspot. Recent population, genetic and phylogenetic studies confirm the evolutionary importance of Lake Kanyaboli in preserving the cichlid fish fauna of Lake Victoria. The adjoining Yala Swamp harbours the endangered swamp antelope Sitatunga (Tragecephalus spekii) and several papyrus endemic birds. The lake and adjoining swamp play a critical role in the livelihood of the local communities who heavily depend on the wetland resources. Current ongoing large scale land use and changes within the swamp threaten the ecological integrity and functioning of this highly dynamic wetland ecosystem. It is therefore imperative that proper management and...

Biodiversity Conservation Under an Imperfect Seed System: The Role of Community Seed Banking Scheme
Provedor de dados: 31
Autores: Bezabih,   Mintewab.
The study is an empirical investigation of agrobiodivestiy conservation decisions of small farmers in the central highlands of Ethiopia.  The primary objective is to measure the effectiveness of Community Seed Banking (CSB) in enhancing diversity while providing production incentives.  We employed Amemiya's GLS estimator to investigate simultaneity between participation and the level of diversity.  Our results indicate a significant impact of participation in CSB on farm-level agrobiodiversity.  However, farmer knowledge and experience associated with biodiversity conservation were not found to hae the expected reinforcing impact on the degree of biodiversity. CSB participation also led to a moderate productivity increase consistent with the need for such...

Bioeconomic Evaluation of Substitution of Balanced Feed with Chaya (Cnidoscolus Chayamansa) Leaves in Tilapia Production
Provedor de dados: 31
Autores: Poot-Lope,   Gaspar Roman; Gasca-Leyva,   Eucario.
In Mexico, the culture of tilapia has developed in rural areas, where the main problem is low producer income.  The state of Yucatan also experiences this situation, and scarcity of money needed to purchase inputs results in complementary feeding with chaya (Cnidoscolus chayamansa), whose leaves are edible for humans and animals.  In this situation, CINVESTAV conducted experiments to determine the optimal level of substitution of balanced feed with ray chaya leaves.  The test with 25% and 50% reduced balanced feed complemented with chaya (ad libitum) did not show significant differences (P&gt;0.05) in growth compared to fishes fed with a complete ration of balanced feed (100% feed table).  A bioeconomic model was developed, including a submodel of growth...

Bioeconomic Model of Community Incentives for Wildlife Management Before and After CAMPFIRE
Provedor de dados: 31
Autores: Fischer,   Carolyn; Muchapondwa,   Edwin; Sterner,   Thomas.
This paper formulates a bioeconomic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe. Two agents influence the wildlife stock: a parks agency determines hunting quotas, and a local community chooses to either aid or discourage outside poachers. Wildlife generates revenues from hunting licenses and tourism; it also intrudes on local agriculture. We consider two benefit-sharing regimes: shares of wildlife tourism rents and shares of hunting licenses. Resource sharing does not necessarily improve community welfare or incentives for wildlife conservation. Results depend on the exact design of the benefit shares, the size of...

Bioeconomic Modeling of the Invasive Aquatic Plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) and their impacts on angler effort on Florida lakes
Provedor de dados: 31
Autores: Adams,   Damian C.; Lee,   Donna J.
The invasive aquatic plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) have the potential to negatively impact recreational use of Florida lakes if consistent, adequate control expenditures are not made. In the mid-1990's, Florida significantly reduced its spending on invasive aquatic plant control measures, which resulted in a significant increase in needed control expenditures in subsequent years. This paper attempts to formalize a relationship between coverage of these invasive aquatic plants and angler effort on Florida lakes using data on 38 lakes over 20 years. Estimated regression coefficients are used to simulate control alternatives, and expenditure cost-benefit comparisons are...

Biogaserzeugung im viehlosen Betrieb: Effekte auf Stickstoffmanagement, Erträge und Qualität
Provedor de dados: 21
Autores: Stinner, Walter; Möller, Dr. Kurt; Leithold, Prof. Dr. Günter.
In organic farming systems without livestock some problems arise concerning the nitrogen management: On the one hand, there is a lack of transportable nitrogen fertilisers, on the other hand there is a potential for high losses with the usual management. The biological N2 fixation is decreased, when clover grass is mulched. If the biomass of intercrops and clover grass gets mineralised in autumn, it can be leached in winter.   In the trial referred to here, the impact of fermentation of biomass on some agricultural parameters like yield etc. are investigated within a crop-rotation of clover grass, potatoes, winter wheat, peas, winter wheat and summer wheat with undersown clover grass. Intercrops are sown after winter wheat and peas.   In the control...

O endocruzamento em populações naturais resulta em uma perda na variabilidade genética que pode influenciar, a mortalidade juvenil e adulta, o tamanho, a viabilidade e fertilidade da prole, bem como a morfologia dos indivíduos. Apanteles piceotrichosus (Blanchard, 1943) (Hymenoptera, Braconidae) é um parasitóide de Plutella xylostella Linnaeus,1758 (Lepidoptera, Yponomeutidae) que tem atraído muita atenção com o propósito de biocontrole, pois pode ser utilizado como agente de controle biológico. Para a criação e liberação destes indivíduos são necessários estudos sobre a sua biologia.

Provedor de dados: 82
Autores: Santos,Karen B. dos; Meneguim,Ana M.; Neves,Pedro M.O.J.
Spodoptera eridania (Cramer) é uma praga em expansão nas culturas de algodão e de soja no cerrado, necessitando de estudos de biologia em diferentes hospedeiros. Com o objetivo de conhecer a biologia e o consumo foliar de S. eridania em algodoeiro, soja e corda-de-viola (Ipomoea grandifolia), este inseto foi criado em laboratório (27± 2ºC, UR 60± 10%, fotofase de 14h), a partir de lagartas recém-eclodidas e individualizadas. Foram observados parâmetros relacionados à biologia, ao consumo foliar e à reprodução quando alimentadas nos três hospedeiros. O período de desenvolvimento larval foi menor nos insetos alimentados com algodoeiro e corda-de-viola do que em soja, embora a sobrevivência em soja tenha sido satisfatória (80%). Lagartas alimentadas com...

Provedor de dados: 97
Autores: ALONSO VEGA,J.M.; VÁSQUEZ,JULIO A.; BUSCHMANN,ALEJANDRO H.
This paper describes the population biology of Lessonia trabeculata and Macrocystis integrifolia during and after the 1997-1998 El Niño in an area of permanent coastal upwelling in northern Chile. Spatial and temporal patterns of distribution were evaluated seasonally for adult and juvenile sporophytes of both species between 1996 and 2003. These two kelp form an assemblage distributed between 2 and 15 m depth, with disjunct patterns along a bathymetric gradient, including two morphs of L. trabeculata, the occurrence of which depends on the presence or absence of M. integrifolia. During the 1997-1998 El Niño the spatial-temporal patterns of abundance of the kelp assemblage were maintained by the continuity of coastal upwelling, which buffered and moderated...

Autores: Alves,Fátima Q.; Argolo,Antônio J.S.; Jim,Jorge.
A biologia reprodutiva de Dipsas neivai Amaral, 1923 e Dipsas catesbyi (Sentezen, 1796) foi estudada através da dissecção de 261 espécimes de D. neivai e 222 de D. catesbyi. Em D. neivai o macho amadurece com menor tamanho do que a fêmea, ocorrendo o oposto em D. catesbyi. Em ambas as espécies a fêmea atinge maior tamanho corporal que o macho. O tamanho da ninhada variou de um a oito ovos em D. neivai e de um a seis em D. catesbyi, não estando correlacionado com o tamanho da fêmea na última. O ciclo reprodutivo em ambos machos e fêmeas é contínuo, com vitelogênese e espermatogênese ocorrendo ao longo do ano todo. Em Dipsas neivai, a cópula nas fêmeas é dissociado da vitelogênese. D. neivai e D. catesbyi são sintópicas, e reproduzem no mesmo período do ano,...

The objective of this investigation was to study Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae), parasitoids of the avocado defoliator Nipteria panacea (Lepidoptera: Geometridae) on the eggs of the alternative host Anagasta kuehniella (Lepidoptera: Pyralidae) aiming to use them for biological control of this pest in avocado orchards. The cubic model presented better adjustment for duration of the life cycle of T. pretiosum and T. acacioi with the host A. kuehniella which shows that development rate of these species increases with temperature within the range tested. The number of individuals of both Trichogramma species emerged per egg from this host was higher than one. The quadratic model was significant for viability of T....

Biological limits on agricultural intensification: an example from resistance management
Provedor de dados: 26
Autores: Laxminarayan, R.; Simpson, D.
Agricultural intensification could reduce pressures on natural habitats, but biological constraints may mitigate the long-term benefits of improved agricultural technologies. We consider one such constraint: that imposed by resistance to pesticides. The application of pesticides places selective evolutionary pressure on pest populations. Those organisms that survive show resistance. Resistance can be managed by planting ‘refuge areas’ in which susceptible pests breed. We use a simple model to characterize the optimal refuge strategy when a social planner values both agricultural output and natural habitat. We also examine land use consequences. The amount of land devoted to agriculture is an increasing function of the discount rate. A related finding is...

In 1978 the DOK long-term field experiment was installed at Therwil close to Basel comparing the farming systems „bio-Dynamic“, „bio-Organic“ and „(K)conventional“. In the first years of the trial, crop yield and feasibility of organic farming were investigated. Soils were analysed with respect to long-term effects on fertility and were evaluated in the view of farming effects on the environment. Today the interrelation of diversity and efficiency and the quality of organic products is the research focus. Long-term trials like the DOK-trial offer unique opportunities for this kind of research.  The DOK-trial compares the three systems mentioned above on the basis of the same intensity of organic fertilization (i.e. the same number of animals per area), the...

In het verleden is al aangetoond dat de biologische productiemethode maatschappelijke voordelen heeft op terreinen als milieu, biodiversiteit, bodemkwaliteit, dierenwelzijn en pesticidenresidu.   Indirect dragen deze kwaliteiten bij aan de gezondheid van de mens.   Nu beginnen ook steeds meer onderzoeksresultaten beschikbaar te komen waaruit blijkt dat de biologische productiemethode ook leidt tot voedsel dat meer gezonde stoffen bevat. Biologische producten blijken gemiddeld gelijk of hoger te scoren op gezonde stoffen o.a. vitamine C gehaltes, mineralen, anti-oxidanten en eiwitkwaliteit dan reguliere producten. En biologische producten blijken gelijk of lager te scoren op ongezonde stoffen zoals nitraat, residuen van bestrijdingsmiddelen en...

In vorliegendem Beitrag wird der Frage nachgegangen, was der Biologische Landbau für eine nachhaltige Entwicklung der Landwirtschaft leisten kann. Aus theoretischer Sicht zeigt sich, dass die Prinzipien der Biologischen Landwirtschaft eine hohe Kompatibilität mit den Zielen einer nachhaltigen Entwicklung aufweisen. Die empirische Überprüfung der festgestellten theoretischen Übereinstimmung kommt zu differenzierten Ergebnissen: Zahlreiche Forschungsergebnisse bestätigen die Vorzüglichkeit des Ökologischen Landbaus in den Nachhaltigkeitsdimensionen Natur, Wirtschaft und Gesellschaft. Allerdings trägt die aktuelle Dynamik in Agrarpolitik, Markt und Produktionstechnik zu einer vermehrt kurzfristig ökonomischen Orientierung der landwirtschaftlichen Produktion...

Biology of Anticarsia gemmatalis on soybean genotypes with different degrees of resistance to insects
Provedor de dados: 63
Autores: Fugi,Cristina Gomes Quevedo; Lourenção,André Luiz; Parra,José Roberto Postali.
A knowledge of the mechanisms of resistance present in genetic materials should help breeding programs in developing cultivars resistant to insects. The biology of Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) was studied on leaves of four soybean genotypes with different degrees of resistance to insects. The genotypes evaluated were cultivars IAC 17 and IAC 24, resistant to defoliators and stink bugs, line PI 229358, a source of multiple resistance to insects and used as parent in various lines selected for resistance to A. gemmatalis, and 'IAC PL-1', the susceptible control. The experiments were carried out in the laboratory, under controlled conditions of temperature (25 ± 2ºC), relative humidity (60 ± 10%) and photoperiod (14h). First instar...

This study provides information on the biology of C. bleekerianus from Paraná State coast, Brazil, assembling data about its abundance, size structure, diet and reproduction. Monthly collections were accomplished in 1999 and 2000 in the internal continental shelf, with trawl net. The catch-per-unit-effort did not vary significantly among the seasons. In the summer, the individuals were larger, followed by autumn, spring and winter. C. bleekerianus was predominantly planktivorous and the most frequent items in its diet were copepods followed by diatomaceous algae. Seasonal variation in the frequency values of the gonad maturation stages, gonadossomatic index and gonadal condition factor indicated that the reproductive period encompassed spring and summer....

Biomass energy in organic farming - the potential role of short rotattion coppice
Provedor de dados: 21
Autores: Jørgensen, Uffe; Dalgaard, Tommy; Kristensen, Erik Steen.
One of the aims of organic farming is to “reduce the use of non-renewable resources (e.g. fossil fuels) to a minimum”. So far, however, only very little progress has been made to introduce renewable energy in organic farming. This paper presents energy balances of Danish organic farming compared with energy balances of conventional farming. In general, the conversion to organic farming leads to a lower energy use (approximately 10% per unit of product). But the production of energy in organic farming is very low compared with the extensive utilisation of straw from conventional farming in Denmark (energy content of straw used for energy production was equivalent to 18% of total energy input in Danish agriculture in 1996).    Biomass is a key energy carrier...

Autores: Sampaio,Everardo V.S.B.; Silva,Grécia C.
Allometric equations to estimate total aboveground alive biomass (B) or crown projection area (C) of ten caatinga species based on plant height (H) and/or stem diameter at ground level (DGL) or at breast height (DBH) were developed. Thirty plants of each species, covering the common range of stem diameters (3 to 50 cm), were measured (C, H, DGL, DBH), cut at the base, separated into parts, weighted and subsampled to determine dry biomass. Wood density (p) of the stem and the largest branches was determined. B, C, H and p ranged from 1 to 500 kg, 0.2 to 112 m², 1.3 to 11.8 m, and 0.45 to 1.03 g cm-3. Biomass of all 10 species, separately or together (excluding one cactus species), could be estimated with high coefficients of determination (R²) using the...

Autores: Sampaio,Paulo de Tarso Barbosa; Barbosa,Antenor Pereira; Vieira,Gil; Spironello,Wilson Roberto; Bruno,Flávio Mauro Souza.
Este estudo propõe uma nova metodologia de exploração do pau-rosa (Aniba rosaeodora Ducke) em substituição ao método tradicional, predatório, de corte raso. Avaliando-se a biomassa da rebrota de copas (galhos e folhas) e de cepas cortadas a 1 m de altura do solo, será possível inferir sobre o manejo de plantios visando maximizar a produção de óleo essencial desta espécie. Os plantios estão localizados na Reserva Florestal Adolph Ducke, Manaus, Brasil. Treze anos após a poda das copas e do corte das árvores a 1 m do solo, o peso seco da rebrota da copa (39,5 kg) foi significativamente superior ao peso seco de galhos e folhas das árvores testemunha (23 kg) e da rebrota das cepas (13,7 kg), revelando que a poda da copa estimulou maior produtividade de galhos...

Autores: CANALS,MAURICIO; GROSSI,BRUNO; IRIARTE-DÍAZ,JOSE; VELOSO,CLAUDIO.
In this study we compared the wing morphology of eight species of bats inhabiting Chile, including two previous studied species. We correlated the results with ecological information. Aspect ratio, wing span, wing area, wing loading and the second moment of area of humerus midshaft were estimated for the molossid Mormopterus kalinowskii, the phyllostomidae Desmodus rotundus and the vespertilionids Histiotus montanus, Histiotus macrotus, Lasiurus borealis, and Lasiurus cinereus. The free-tailed bats T. brasiliensis and M.kalinowskii and D. rotundus, without uropatagyum, showed a low wing area, but whilst the molossids showed large aspect ratios, that of D. rotundus was only moderate. Desmodus rotundus showed the lowest wing span (relative to the expected...

Biophysical isopycnic-coordinate modelling of plankton dynamics in the Arabian Sea
Provedor de dados: 20
Autores: Idrisi, N.; Romanou, A.; Olascoaga, M.J.
A Nutrients-Phytoplankton-Zooplankton-Detritus (NPZD) ecosystem model is coupled to the Miami Isopycnic-Coordinate Ocean Model (MICOM) to study planktondynamics in the Arabian Sea. Experiments oriented to testing the NPZD-MICOM coupled model sensitivity to variations in several parameters are performed. Particular attention is paid to the rates of detritus sinking and maximum phytoplankton growth rate. The coarse features of the blooms are captured by all the experiments considered, and agree with earlier models for the biological activity of the region. Intensity, duration, and peaks of the blooms are found to be quite sensitive to the parameter choices. The existence of an offshore deep chlorophyll maximum in the model is found to be closely related to...

Autores: Musa-Steenblock, Tomke; Forrer, Hans-Rudolf.
In organic potato production, copper fungicides are the only mean for an effective direct control of late blight. To avoid negative impacts of copper accumulation in the environment, intensive research is done to develop efficient copper free agents (CFA) and new strategies for disease prevention. However, the search for such CFA and strategies proves to be more difficult than expected. Therefore an abdication of copper products is not yet possible. To approach a copper free organic potato production, the Agroscope FAL Reckenholz is developing the Bio-PhytoPRE decision support system to assist Swiss organic potato producers to control late blight with reduced amounts of copper or CFA.

Biopigments from Monascus: strains selection, citrinin production and color stability
Provedor de dados: 52
Autores: Carvalho,Júlio Cesar de; Oishi,Bruno Oliva; Pandey,Ashok; Soccol,Carlos Ricardo.
Fungi form the genus Monascus are a promising source for natural color additives. However, before effectively applying Monascus to foods, it is important to select strains which produce large amounts of biopigments but little or no citrinin, a mycotoxin usually also produced by these fungi. Also, color stability of these pigments should be properly investigated. In order to compare Monascus strains for biopigment production in solid substrate fermentation (SSF), 4 strains (NRRL 1991, NRRL 2897, CCT 3802 and LPB 31) were cultivated over PDA in Petri dishes, and compared for radial growth velocity. Also, these strains were cultivated over cooked rice, and compared in relation to their capacity to produce biopigments and citrinin. The results showed that the...

Land patterns are beautiful, fascinating, dynamic, and significant to so many life processes. Capacity to understand landscape patterns can arise from very different paradigms; i) through the fine arts, an ability to see patterns; ii) from language arts, the gift to read and describe the landscape; iii) from the geographic sciences, the ability to map, measure, and interpret patterns; and iv) from environmental design, the drive to integrate the above capacities. Under many circumstances, landscape studies or conservation could be enhanced using multiple approaches to capture the complex dynamics of people and land in a holistic framework. Long-held paradigms about how knowledge is acquired and applied in the ecological sciences may be trespassed. Linking...

Biosecurity and Infectious Animal Disease

Autores: Hennessy,   David A.
The spatial dimension of agricultural production is important when a communicable disease enters a region. This paper considers two sorts of biosecurity risk that producers can seek to protect against. One concerns the risk of spread: that neighboring producers do not take due care in protecting against being infected by a disease already in the region. In this case, producer efforts substitute with those of near neighbors. For representative spatial production structures, we characterize Nash equilibrium protection levels and show how spatial production structure matters. The other sort of risk concerns entry: that producers do not take due care in preventing the disease from entering the region. In this case, producer heterogeneity has subtle effects on...

Autores: Corrêa,Rodrigo Studart; White,Robert E.; Weatherley,Anthony J.
Biosolids have been reported to increase yields and supply plant nutrients. However, complying with health and environmental standards is necessary before applying biosolids to land. Thus, sludge stabilization is required to make biosolids safe enough for their agricultural use. Side effects of stabilization processes on agronomic features of sewage sludge are not quite known, although their understanding is essential for biosolids management. Based on a model equivalent to the Mitscherlich equation, effects of the most common processes for sludge stabilization were evaluated (composting, liming, heat-drying and solar irradiation) in relation to the agronomic effectiveness of biosolids to yield Lolium perenne L. on two tropical soils, with NH4H2PO4 as a...

Autores: Ahalya,N; Kanamadi,R.D; Ramachandra,T.V.
The potential to remove Cr (VI) from aqueous solutions through biosorption using the husk of Bengal gram (Cicer arientinum), was investigated in batch experiments. The results showed removal of 99.9% of chromium in the 10 mgl-1 chromium solution, the biomass required at saturation was 1 g mg-1. Kinetic experiments revealed that the dilute chromium solutions reached equilibrium within 180 min. The biosorptive capacity of the (bgh) was dependent on the pH of the chromium solution, with pH 2 being optimal. The adsorption data fit well with the Langmuir and Freundlich isotherm models. The adsorption capacity calculated from the Langmuir isotherm was 91.64 mg Cr (VI)/g at pH 2. The adsorption capacity increased with increase in agitation speed and an optimum...

Biosystematic and chemosystematic studies in five South American species of Conyza (Asteraceae)
Provedor de dados: 51
Autores: Urdampilleta,Juan D.; Amat,Aníbal G.; Bidau,Claudio J.; Kolb Koslobsky,Nicolás.
The composition of the essentials oils of five species of Conyza Less from Argentina was determined by Gas Chromatography-Mass Spectrometer. This composition is associated to morphological and cytogenetic characters. The monoterpenes constitute more than 60% of the essential oils in C. blakei, C glandulitecta, C. sumatrensis var. sumatrensis and C. sumatrensis var. floribunda, in which limonene is the predominant compound. In C. bonariensis and C. primulaefolia the monoterpene content constitute less than the 40%. C. bonariensis presents only 13% limonene, while in C. primulaefolia it is absent. The similarity analysis of monoterpenes showed a relationship between the morphological and cytogenetic analysis, and the monoterpene content character seems to be...

Biotechnology, the US-EU dispute and the Precautionary Principle
Provedor de dados: 26
Autores: Van den Belt, H.
The international debate on biotechnology is extremely polarized. Opponents such as Greenpeace International, Friends of the Earth and other NGOs often invoke the Precautionary Principle to advance their cause. The principle is also at issue in trade disputes between the USA and the European Union. There are several versions of the Precautionary Principle in circulation. The strong version adopted by many environmentalist organizations is logically untenable, while the weaker versions espoused by the European Commission and enshrined in international treaties are rather vague and ill-defined. The contested role of the Precautionary Principle bears testimony to public ambivalence towards scientific expertise in modern risk societies. A more open and...

Birnenpockenmilbe: Nacherntebehandlung mit Schwefel
Provedor de dados: 21
Autores: Höhn, Heinrich; Linder, Christian; Daniel, Claudia; Wyss, Eric.
Die verschiedenen Exakt- und Praxisversuche sowie die ersten Erfahrungen von Praxisanwendungen zeigen, dass mit einer Nacherntebehandlung mit 2% Schwefel (entspricht 32 kg/ha bei einem Baumvolumen von 10 000 m3/ha) eine erfolgreiche Bekämpfungsmöglichkeit gegen Birnpockenmilben vorliegt. Raubmilben werden nach unserer Erfahrung kaum beeinflusst, da sie zu diesem Zeitpunkt bereits weitgehend die Winterquartiere bezogen haben. Auch andere negative Auswirkungen konnten wir bis jetzt nicht feststellen. Unter Berücksichtigung aller bisher bekannten Fakten muss in Zukunft für die Birnpockenmilbenbekämpfung bevorzugt die neu bewilligte Herbstbehandlung mit Schwefel empfohlen werden.

Biweekly current oscillations on the continental slope of the Gulf of Guinea
Provedor de dados: 5
Autores: Vangriesheim, Annick; Treguier, Anne-marie; Andre, Gael.
Current meter measurements have been carried out for 3 years on the continental slope of the Gulf of Guinea, near 7.5 degrees S off the Angola coast. Currents in a water depth of 1300 m over the continental slope show a remarkable biweekly oscillation, bottom intensified, and with currents oriented nearly parallel to the isobaths. With a peak-to-peak amplitude reaching 20-30 cm s(-1) at 30 in above the bottom, this signal is the most energetic at sub-inertial frequencies. Simultaneous measurements deeper on the continental rise (in a water depth of 4000 m) show a more complex signal dominated by lower frequencies, and with less clear polarization. Simple linear topographic wave theories are compared to the observations. A combination of coastal trapped...

Bladsygdomme på byg afhænger af sort, placering i sædskiftet og gødningstype
Provedor de dados: 21
Autores: Hovmøller, M.S.; Berntsen, J.; Thomsen, I.
Plantesygdomme i økologisk planteproduktion har stor indflydelse på produktkvalitet og udbytte. Specielt i korn er der gode muligheder for at forebygge svampesygdomme ved hjælp af sortsresistens, idet mange års planteforædling har bidraget til at øge niveauet af resistens mod de mest betydende svampesygdomme. Dette gælder bl.a. resistens mod bladsvampe som meldug, bygrust, skoldplet og forskellige bladpletsvampe.    En sorts resistensniveau mod en given svampesygdom er imidlertid ikke konstant, men kan ændre sig over tid og have forskellig effekt i forskellige dele af landet. Det skyldes primært forskelle og dynamik i de patogenpopulationer, som forårsager de pågældende sygdomme. Derudover er sygdomsniveauet i den enkelte mark afhængig af det lokale...

Blight-MOP: Development of a systems approach for the management of late blight (caused by Phytophthora infestans) in EU organic potato production
Provedor de dados: 21
Autores: Leifert, C.; Wilcockson, S.J.
Blight-MOP  Late blight (caused by Phytophthora infestans) is the most devastating fungal disease affecting organic (and conventional) potato production in the EU. It kills the foliage and usually results in losses of yield which can be very large when infection is severe and occurs early in the season. The disease may be transmitted to the tubers which become unmarketable and these can lead to complete deterioration of the stored crop if put into storage with healthy tubers. To a great extent, conventional production systems rely upon frequent applications of synthetic fungicides with different modes of action for late blight control, but this is seldom completely successful. However, in organic systems, the availability of chemical fungicides is...

Blood flow measurements in rats using four color microspheres during blockade of different vasopressor systems
Provedor de dados: 56
Autores: De Angelis,K.; Gama,V.M.; Farah,V.A.M.; Irigoyen,M.C.
The use of colored microspheres to adequately evaluate blood flow changes under different circumstances in the same rat has been validated with a maximum of three different colors due to methodological limitations. The aim of the present study was to validate the use of four different colors measuring four repeated blood flow changes in the same rat to assess the role of vasopressor systems in controlling arterial pressure (AP). Red (150,000), white (200,000), yellow (150,000), and blue (200,000) colored microspheres were infused into the left ventricle of 6 male Wistar rats 1) at rest and 2) after vasopressin (aAVP, 10 µg/kg, iv), 3) renin-angiotensin (losartan, 10 mg/kg, iv), and 4) sympathetic system blockade (hexamethonium, 20 mg/kg, iv) to determine...

Bluetongue in the Mediterranean: prediction of risk in space and time
Provedor de dados: 26
Autores: Purse, B.V.; Mellor, P.S.; Baylis, M.
Bluetongue virus (BTV) causes an infectious, non-contagious disease of ruminants and is transmitted by Culicoides biting midges. Currently an unprecedented epidemic of bluetongue (BT) is sweeping the Mediterranean Basin and a large number of countries are now involved in managing the disease. Therefore the development of new methods for accurate prediction of BT risk in space and time is essential. The life-history parameters of Culicoides and other parameters of the BTV transmission cycle are highly sensitive to climatic conditions. Thus the potential exists to define the limiting conditions and likelihood of spread of BTV, using geographical information systems (GIS) to combine vector, virus and environmental information. This paper reviews the progress...

Bodenerosion und Oberflächenabfluss auf einer ökologisch bewirtschafteten Ackerfläche im Sächsischen Lößhügelland
Provedor de dados: 21
Autores: Michel, Jana; Nitzsche, Dr. Olaf; Hänsel, Martin.
A rainfall simulator was used to describe soil erosion and surface flow on a long-term organically cultivated field. Both parameters did not show differences to conventionally managed and ploughed fields in the same region. These results indicate that soil erosion is fairly independent from the farming system (organic or conventional) but mainly depends on the tillage method.

Los moluscos bivalvos son organismos sedentarios que establecen una relación íntima no sólo entre ellos, sino también con el espacio que ocupan y con sus condiciones fisicoquímicas. Sus poblaciones pueden ser hospedadoras de múltiples organismos patógenos (virus,bacterias, hongos, protistas y metazoos), cuya presencia es regulada eficazmente a niveles  infra, meta y suprapoblacionales en ambientes silvestres, no provocando, salvo  excepcionalmente, impactos severos. Los cultivos a escala comercial producen concentraciones de individuos, con la consiguiente alteración del medio y del equilibrio natural en la relación parásito-hospedador, generándose condiciones apropiadas para el desarrollo de enfermedades. Entre los años 1995 y 1996 se instala, en la zona...

Autores: Castro,T.C.M. de; Terreri,M.T.R.A.; Szejnfeld,V.L.; Len,C.; Fonseca,A.S.M. da; Hilário,M.O.E.
We measured bone mineral density (BMD) in girls with juvenile dermatomyositis (JDM) considering multiple factors in order to determine if it could be used as a predictor of reduction in bone mass. A cross-sectional study of lumbar spine BMD (L2-L4) was conducted on 10 girls aged 7-16 years with JDM. A group of 20 age-matched healthy girls was used as control. Lumbar spine BMD was measured by dual-energy X-ray absorptiometry. Weight, height and pubertal Tanner stage were determined in all patients and controls. Duration of disease and mean daily and cumulative steroid doses were calculated for all patients on the basis of their medical charts. JDM activity was determined on the basis of the presence of muscle weakness, cutaneous vasculitis and/or elevation...

Bone morphogenetic proteins: from structure to clinical use
Provedor de dados: 56
Autores: Granjeiro,J.M.; Oliveira,R.C.; Bustos-Valenzuela,J.C.; Sogayar,M.C.; Taga,R.
Bone morphogenetic proteins (BMPs) are multi-functional growth factors belonging to the transforming growth factor ß superfamily. Family members are expressed during limb development, endochondral ossification, early fracture, and cartilage repair. The activity of BMPs was first identified in the 1960s but the proteins responsible for bone induction were unknown until the purification and cloning of human BMPs in the 1980s. To date, about 15 BMP family members have been identified and characterized. The signal triggered by BMPs is transduced through serine/threonine kinase receptors, type I and II subtypes. Three type I receptors have been shown to bind BMP ligands, namely: type IA and IB BMP receptors and type IA activin receptors. BMPs seem to be...

Bony fish bycatch in the southern Brazil pink shrimp (Farfantepenaeus brasiliensis and F. paulensis) fishery
Provedor de dados: 52
Autores: Vianna,Marcelo; Almeida,Tabajara.
Trawling for pink shrimp (Farfantepenaeus brasiliensis and F. paulensis) catches also large quantities of fish, mostly bony fish, which are discarded, as they have no commercial value. Their composition and abundance were studied in an area that corresponded to the southeastern coastline of Brazil. Ninety one species were registered. Incidental fishing affected mainly small individuals and occured throughout the year. The year round rate of bony fish to shrimp catches was 10,5:1,0. Three assemblages of bony fishes could be identified, influenced by the seasonal variation of the water masses, the predominant group being associated with the Coastal Water, another with the penetration of colder waters onto the platform (SACW) and a third group of a more...

This long awaited manual gives cultural descriptions of 223 specific and infra-specific taxa of Phoma (Coelomycetes). Fungi of this genus are common, but have always been difficult to identify. But now this book will make identification easier. It provides line drawings and keys for the identification of common pathogenic and saprotrophic species of Phoma in vitro, with references to additional diagnostic literature, representative cultures and documentation of the numerous synonyms (1,146 in total) formerly used in the mycological and phytopathological literature. Part of the book has been published before in the series ‘Contributions towards a monograph of Phoma’, also partly in Persoonia. Most of the Phoma-species in this book are widespread in western...

Surprisingly little is known about New Zealand’s fungi, of which many are believed to be unique to New Zealand. The authors estimate that about 2/3 of the expected 22,000 species are unrecorded. This first volume seeks to provide a foundation for understanding New Zealand’s fungi, including taxonomic, ecological, historical and cultural knowledge, along with inventories of recorded species. It is a cooperative initiative by several New Zealand mycologists and a Swiss mycologist (Horak). The next volumes will provide monographic treatments of selected taxonomic or ecological groups of fungi. The book starts with an abstract in English and Maori, and 16 coloured plates which illustrate some of the more conspicuous, colourful and distinctive species found in...

Boosted regression (boosting): An introductory tutorial and a Stata plugin
Provedor de dados: 31
Autores: Schonlau,   Matthias.
Boosting, or boosted regression, is a recent data-mining technique that has shown considerable success in predictive accuracy. This article gives an overview of boosting and introduces a new Stata command, boost, that implements the boosting algorithm described in Hastie, Tibshirani, and Friedman (2001, 322). The plugin is illustrated with a Gaussian and a logistic regression example. In the Gaussian regression example, the R2 value computed on a test dataset is R2 = 21.3% for linear regression and R2 = 93.8% for boosting. In the logistic regression example, stepwise logistic regression correctly classifies 54.1% of the observations in a test dataset versus 76.0% for boosted logistic regression. Currently, boost accommodates Gaussian (normal), logistic,...

BORÉRTÉKESÍTÉSI KIHÍVÁSOK ELEMZÉSE
Provedor de dados: 31
Autores: Doman,   Szilvia.
Klaszterelemzés segítségével a vizsgálatban szereplő üzemek jellemzői alap-ján három eltérő kategória különböztethető meg: a befutott kisüzemek, a prob-lematikus középüzemek és a piacvezető nagyüzemek. Megállapítható, hogy a bo-rászati üzemek három kategóriájának jelenlegi helyzete, piaci viselkedése, kilá-tásai erősen eltérők, következésképpen stratégiájuk is csak eltérő lehet. Kritikus helyzetűek a középüzemek, amelyek túl nagyok ahhoz, hogy a kis-üzemek által használt (és várhatóan még tartósan megmaradó) értékesítési csa-tornákban gondolkodjanak, ahhoz viszont kicsik, hogy a valódi nagyvállalatok-hoz hasonlóan a nagy üzletláncokban is megjelenjenek.

"Born out of Crisis": an analysis of moorland management agreements on Exmoor; final report
Provedor de dados: 31
Autores: Lobley,   Matt; Turner,   Martin M.; MacQueen,   Greg; Wakefield,   Dawn.
The designation of Exmoor National Park in 1954 recognised the importance of the open character of much of the area and, in particular, its moorland to that natural heritage of the UK. However, the moorland that the park was charged with maintaining and enhancing was soon under threat and the following years saw extensive moorland loss and the fragmentation of remaining moorland (Lowe et al, 1986). The ensuing moorland conflict and debate eventually lead Exmoor NPA, in collaboration with farmers, land owners, the CLA and NFU to pioneer a new system of moorland management agreements. Indeed, for a short time, Exmoor was the only location operating wholly voluntary management agreements (Brotherton, 1990). Only two agreements now remain and in the...

Autores: Corrêa,Juliano Corulli; Esteves,José Antônio de Fátima; Grassi Filho,Helio; Alves,Elza; Ceccon,Gessi.
No reports are registered on responses to boron fertilization nutrient deficiency and toxicity in triticale crops. The aim of this study was to evaluate triticale response to different rates of boron in comparison to wheat in an hapludox with initial boron level at 0.08 mg dm-3 4 &lt;FONT FACE=Symbol&gt;´&lt;/FONT&gt; 4 factorial design trial completely randomized blocks design (n = 4). Boron rates were 0; 0.62; 1.24 and 1.86 mg dm-3; triticale cultivars were IAC 3, BR 4 and BR 53 and IAPAR 38 wheat crop was used for comparison. The wheat (IAPAR 38) crop presented the highest boron absorption level of all. Among triticale cultivars, the most responsive was IAC 53, presenting similar characteristics to wheat, followed by BR 4; these two crops are considered...

Boron transport in Eucalyptus. 2. Identification in silico of a putative boron transporter for xylem loading in eucalypt

Boron (B) is a low mobility plant micronutrient whose molecular mechanisms of absorption and translocation are still controversial. Many factors are involved in tolerance to Boron excess or deficiency. Recently, the first protein linked to boron transport in biological systems, BOR1, was characterized in Arabidopsis thaliana. This protein is involved in boron xylem loading and is similar to bicarbonate transporters found in animals. There are indications that BOR1 is a member of a conserved protein family in plants. In this work, FORESTS database was used to identify sequences similar to this protein family, looking for a probable BOR1 homolog in eucalypt. We found five consensus sequences similar to BOR1; three of them were then used in multiple alignment...

Borreria santacruciana y Mitracarpus bicrucis (Rubiaceae - Spermacoceae), nuevas especies de Bolivia
Provedor de dados: 66
Autores: Bacigalupo,Nélida M.; Cabral,Elsa L.
Dos especies nuevas de Bolivia, Borreria santacruciana y Mitracarpus bicrucis, se describen e ilustran. B. santacruciana es afín a B. wunschmanii, pero difiere por tener una pubescencia inconspicua de pelos adpresos, hojas de 7-17 mm long., y glomérulos con 2-4 brácteas de 7-13 mm long. Mitracarpus bicrucis es enteramente glabro, notable por su vaina estipular con una sola lacinia y por el surco en forma de cruz en ambas caras de la semilla.

Børsterensning kan reducere stinkbrand i hvede
Provedor de dados: 21
Autores: Borgen, Anders.
Stinkbrand i hvede (Tilletia tritici) er tilstede i såsæden som frie svampesporer. De enkelte kerner er ikke inficerede ved høst, men efter såning spirer sporerne samtidig med kornet, og de fremspirende planter bliver så inficeret af svampen. Stinkbranden kan derudover også være til stede i såsæden som brandbutter, det vil sige de kornlignende sporefyldte sori, som sygdommen danner i hvedeakset.

Bovine spongiform encephalopathy in Japan: consumers’ food safety perceptions and willingness to pay for tested beef
Provedor de dados: 31
Autores: McCluskey,   Jill J.; Grimsrud,   Kristine M.; Ouchi,   Hiromi; Wahl,   Thomas I.
The discovery of bovine spongiform encephalopathy (BSE), commonly known as ‘mad cow disease’, in Japan caused anxiety about consuming beef and beef products. As a result, there was a sudden fall in sales of beef that hurt the Japanese beef industry as well as major beef exporters to Japan. We analyse factors that affect Japanese consumers’ willingness to pay (WTP) price premiums for BSE-tested beef and estimate the mean WTP for BSE-tested beef using data obtained from a consumer survey in Japan. A single-bounded dichotomous choice contingent valuation model is used to recover the premium amount. We find that attitudes to food safety, reduction in beef consumption following the BSE outbreak, and being female all have a statistically significant positive...

Bovine viral diarrhea diagnostic: immunohistochemistry standardization for routine
Provedor de dados: 45
Autores: Andrade,G.I.; Serra,C.V.; Barbosa-Stancioli,E.F.; Serakides,R.; Lobato,Z.I.P.
The immunohistochemistry standardization for bovine viral diarrhea virus (BVDV) diagnostic was described. The formalin-fixed tissue samples from a heifer with mucosal disease were used as positive control. The validation of the first phase results was performed using samples from an aborted fetus and a calf infected with reference strains of BVDV. The best results were seen using monoclonal antibodies and a commercial kit consisting of labelled streptavidin biotin (LSAB) reagents and the diaminobenzidine (DAB) substrate-chromogen reagent. The immunohistochemistry demonstrated to be an useful method for routine diagnosis for the controll and detection of BVDV infection.

The article’s aim is to conduct a comparative cross-section analysis of the innovative behaviour of the German manufacturing industry. The peculiarities of the food industry are tested in a combined analysis based on both input and output indicators. Linear and logistic regressions are used to investigate the differences between the food industry and other branches of the manufacturing industry. In comparison to other branches, the food industry has lower research &amp; development (R&amp;D) expenditures whereas the import of research from more technology intensive sectors is high. Most of the released new products are improvements and imitations. Market novelties are rare. The development time for new products is relatively short compared to other...

Brassica cover crops for weed control in organic vegetable production
Provedor de dados: 21
Autores: Kristiansen, P.; Sindel, B.M.; Jessop, R.; Cerrai, D.
Cover crops (or green manures) are commonly used by organic vegetable growers for soil fertility building and other benefits including weed control. Brassica crops have been reported to control weeds in subsequent crops, usually attributed to the allelopathic effects of glucosinolates (GSL) in the brassica residues, although the effects are inconsistent. New brassica varieties with high GSL levels (Brassica juncea cv. Fumus and Raphanus sativus cv. Weedcheck) were tested in combination with mechanical weed control and another locally grown forage crop (Lolium multiflorum cv. Conquest) for their effects on weed growth during the pre-crop phase and subsequent weed and lettuce growth during the in-crop phase. The cover crops and bare fallow controlled weeds...

Brazilian Agricultural Credit Interest Rate Equalization Policy: A Growth Subsidy?
Provedor de dados: 31
Autores: Castro,   Eduardo Rodrigues de; Teixeira,   Erly Cardoso.
The Brazilian Interest Rate Equalization System (IRES) subsidizes farmers by providing them with credit at lower than market interest rates. The objective of this research is to evaluate the IRES by comparing its monetary cost with its benefits as measured by Brazilian GDP growth. Estimates are carried out using input-output matrix. The results suggest that each Brazilian real spent by IRES to assist Brazilian family farms increases Brazilian GDP by R$ 1.75 and that each real spent to assist commercial farms increases GDP by R$ 3.57. The IRES is a subsidy that generates economic growth greater than its cost to society.

“Bright spots” in Uzbekistan, reversing land and water degradation while improving livelihoods: Key developments and sustaining ingredients for transition economies of the former Soviet Union
Provedor de dados: 31
Autores: Noble,   Andrew D.; Ul Hassan,   Mehmood; Kazbekov,   Jusipbek.
Following the dissolution of the former Soviet Union and the collapse of existing trade arrangements, the newly independent states of Central Asia were left with the task of developing their own independent market economies. The region has undergone tremendous economic and social changes including significant agricultural reform mainly targeted at privatizing large collective farms that were established during the Soviet era. These reforms include the establishment of smaller private and cooperative farms in order to improve the efficiency and equity of existing production systems. Within Uzbekistan, this move to privatize farms has, in the majority of cases, led to declining productivity and net incomes. However, there have been instances where privatized...

Brochosomes-for-eggs of the Proconiini (Hemiptera: Cicadellidae, Cicadellinae) species associated with orchards of Citrus sinensis (L.) Osbeck in Rio Grande do Sul, Brazil
Provedor de dados: 82
Autores: Azevedo-Filho,Wilson S. de; Carvalho,Gervásio S.
Brochosomes are ultramicroscopic reticulate bodies produced by the Malpighian tubules of leafhoppers. Brochosomes are usually either spherical (brochosomes-for-integument) or elongated (brochosomes-for-eggs). In this study, the Proconiini species were diagnosed according to their brochosomes-for-eggs. Brochosome-for-eggs traits and dichotomous key were also discussed. The specimens were collected in nine orchards of Citrus sinensis (Valencia orange), using yellow sticky traps. The orchards are located in seven counties in the state of Rio Grande do Sul: Tenente Portela, Ijuí, Jaguari, Harmonia, Taquari, Montenegro, and Pelotas.

With the aim of investigating the presence of latent inflammatory process in the lungs of patients with Crohn's disease, 15 patients with Crohn's disease were evaluated by spirometry, the methacholine challenge test, induced sputum, and skin tests for inhaled antigens. Serum IgE, erythrocyte sedimentation rate and hematocrit were also determined. The patients were compared with 20 healthy controls by the Mann-Whitney and Fisher exact tests. Their respiratory physical examination was normal. None had a personal or family history of clinical atopy. None had a previous history of pulmonary disease, smoking or toxic bronchopulmonary exposure. None had sinusitis, migraine, diabetes mellitus, or cardiac failure. Four (26.6%) of the patients with Crohn's disease...

Provedor de dados: 14
O Estado do Pará é o maior produtor de açaí. Só em Belém, estima-se que haja cerca de três mil pontos de venda de açaí já processado e um consumo diário em torno de 440 mil quilos. Embora a predominância dessa produção seja oriunda de açaizais nativos, o Pará deve ter hoje 3.500 hectares de açaizais cultivados em condições de terra firme, só que originários de sementes que não passam por nenhum critério de seleção e trazem consigo variações de produtividade e de rendimento da polpa. Com o desenvolvimento da BRS-Pará, o país conta com um material genético adaptado às condições idéias para o êxito da cultura. A BRS-Pará apresenta como principais características: alta produtividade, precocidade no início da produção (aos 3 anos, ou seja, um ano a menos do que...

Danish farmers are required to grow around 300.000 hektares of catch crops each year, as part of the Danish regulations of N use and losses from agriculture. The rules set some minimum requirements about how to grow catch crops, but do not attempt to optimize the effects of the catch crops. In the paper it is discussed how farmers can improve the effects of catch crops, both the environmental effects and the effects on nitrogen supply for succeeding agricultural crops. It is shown that it is highly important which plant species are grown, as there are large differences in their root growth and winter hardines. It is also shown that the species choice may have suprising large effects on the N supply for the succeeding crop.

Brush cleaning to remove fungal spores from seed lots
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt is infecting wheat seedling just after sowing, in the heterotrophic phase before seedling emergence. The seed per se is healthy at the time of sowing, but gets infected from spores resting on the seed surface.  Bechel et al. 1998 has shown that only a minor fraction of the spores of the the closely related bunt species T.contraversa in a seed lot end up in the flour, while the majority are removed during the cleaning of the seed before or during milling. However, little is known about the destiny of the spores during the cleaning process of seed intented for sowing.  Seed lots contaminated with bunt spores during threshing was cleaned in a brush cleaner (ø=400mm) (http://www.westrup.com/HAsideeng.htm) with and without precleaning. Airstream...

BSE, U.S. Beef Trade and Cattle Feeding Industry

Autores: Almas,   Lal K.; Colette,   W. Arden; Amosson,   Stephen H.
A brief review of the beef and cattle market following the diagnosis of Bovine Spongiform Encephalopathy (BSE) in Canada and U.S. in 2003 is conducted.   The focus is on the recent changes in the beef market experienced by major exporting and importing countries with special emphasis on the beef trade and cattle industry in the U.S. A single case of BSE in the U.S. has significantly disrupted global beef trade.  Many countries banned beef imports from the U.S. and Canada.  Continuation of these bans through 2004, particularly for the U.S., resulted in reduced beef exports.  Brazil has become the number one beef exporter with estimated exports of 1.47 million tons in 2004 and is forecast to export 1.62 million tons in 2005.  U.S. is the largest beef...

Bt Corn Farmer Compliance with Insect Resistance Management Requirements: Results from the 2002 Minnesota and Wisconsin Farm Polls
Provedor de dados: 31
Autores: Buttel,   Frederick H.; Merrill,   Jeanne; Chen,   Lucy; Goldberger,   Jessica; Hurley,   Terrance M.
The U.S. Environmental Protection Agency (EPA) reregistered Bt corn in 2001 with mandatory Insect Resistance Management (IRM) requirements in order to promote sustainable use by farmers.  Since then studies report IRM compliance rates ranging from 80 to 90 percent.  Using survey data from Minnesota and Wisconsin, we show that previous compliance rate estimates are likely too high because they do not use a comprehensive measure for compliance.  With a more comprehensive measure, we find compliance rates ranging between 60 to 75 percent.

Buckley–James method for analyzing censored data, with an application to a cardiovascular disease and an HIV/AIDS study
Provedor de dados: 31
Autores: Cui,   James.
The Buckley–James method and the Cox proportional hazards model were proposed in the 1970s. Both methods can be used to analyze survival-type data, although the former focuses on calculation of the expected value of the survival time and the latter on the relative risk of explanatory variables on the failure event. In cardiovascular disease epidemiological studies, it is essential to correct the effect of taking antihypertensive medicine, which means we need to calculate the expected blood pressure for people who take the medicine. I developed a Stata program to calculate the Buckley–James estimate. I will describe how to use this program to calculate the expected value of a censored outcome and illustrate the method through an example from a...

Die Forschungsanstalt RAC Changins will auf die Weiterführung der offiziellen biologischen Getreidesortenprüfung verzichten. Für die biologische Getreidezüchtung bedeutet dies einen schweren Rückschlag, denn die Aufnahme in den nationalen Sortenkatalog ist zwingende Voraussetzung für die Handelbarkeit einer neuen Getreidesorte. Künftig soll die offizielle Sortenprüfung an neun Extensostandorten sowie, als Feigenblatt, auf einem Biobetrieb durchgeführt werden. Der Entscheid des Bundes sorgt für erstauntes Kopfschütteln unter den Fachleuten.

This paper investigates the relationship between a bureaucracy and mass media industry, and its implications to corruption. We develop a bureaucratic model of corruption with mass media. A representative profit maximizing media firm seeks for corruption news to be printed and sold. Channels through which competition in media industry and press freedom affect equilibrium corruption in a bureaucracy are modeled.  Different degrees of media freedom and competition affect production and employment decisions of media firms, and this in turn affects the effectiveness of media in monitoring corruption. Competition and freedom in media sector also have an influence on bureaucratic structure and consequently on equilibrium corruption. We find that the degree of...

BUSINESS GROWTH STRATEGIES OF ILLINOIS FARMS: A QUANTILE REGRESSION APPROACH
Provedor de dados: 31
Autores: Hennings,   Enrique; Katchova,   Ani L.
This study examines the business strategies employed by Illinois farms to maintain equity growth using quantile regression analysis. Using data from the Farm Business Farm Management system, this study finds that the effect of different business strategies on equity growth rates differs between quantiles. Financial management strategies have a positive effect for farms situated in the highest quantile of equity growth, while for farms in the lowest quantile the effect on equity growth is negative.  Cost reduction, asset management and revenue enhancement strategies all proved to have important effects on the determination of growth equity rates.

Autores: Hueth,   Brent; Ibarburu,   Maro A.; Kliebenstein,   James B.
We study business organization and coordination of specialty-market hog production using a comparative analysis of two Iowa pork niche-marketing firms. We describe and analyze each firm's management of five key organizational challenges: planning and logistics, quality assurance, process verification and management of "credence attributes," business structure, and profit sharing. Although each firm is engaged in essentially the same activity, there are substantial differences across the two firms in the way production and marketing are coordinated. These differences are partly explained by the relative size and age of each firm, thus highlighting the importance of organizational evolution in agricultural markets, but are also partly the result of a formal...

Business Partnerships in a Globalising World: Economic Considerations
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Begins by considering how neoclassical and mainstream economists have modelled the business firm and outlines briefly the evolution of economic thought and that of managerial science about institutional structures involving firms, hierarchies, markets and interfirm cooperation. Subsequently, taking into account this thought, it considers whether growing economic globalisation is likely to result in more frequent business cooperation between firms, what types of alliances may be favoured, and why. Both factors favouring increased business cooperation as globalisation proceeds, as well as those that may retard it, are discussed.

Business and financial records for 2004 from 200 New York dairy farm businesses are summarized and analyzed. This analysis demonstrates the use of cash accounting with accrual adjustments to measure farm profitability, financial performance, and costs of producing milk. Traditional methods of analyzing dairy farm businesses are combined with evaluation techniques that show the relationship between good management performance and financial success. The farms in the project averaged 334 cows per farm and 22,070 pounds of milk sold per cow, which represent above average size and management level for New York dairy farms. Net farm income excluding appreciation, which is the return to the operator's labor, management, capital, and other unpaid family labor,...

In this paper we attempt to compare the responses of consumers and professionals to questions related to organic food retailing, in order to highlight the differences and the similarities of viewpoints between them and to understand the links between consumer perception of organic food and the sales channel. In order to do this, we analyse the results of three studies, two of them conducted with consumers, the third one with professionals. The first study deals with the links between consumer trust orientations and the frequentation of the different sales channels where organic food can be found. The results of this study conducted in France and Germany show that consumers in organic food stores put trust in their store but are neither the heaviest nor the...

C- and Sr-isotope stratigraphy of the São Caetano complex, Northeastern Brazil: a contribution to the study of the Meso-Neoproterozoic seawater geochemistry
Provedor de dados: 42
Autores: Silva,Juan C.; Sial,Alcides N.; Ferreira,Valderez P.; Pimentel,Márcio M.
C-isotope and 87Sr/86Sr values for five carbonate successions from the São Caetano Complex, northeastern Brazil, were used to constrain their depositional age and to determine large variations in the C- and Sr-isotopic composition of seawater under the framework of global tectonic events. Three C-isotope stages were identified from base to top in a composed chemostratigraphic section: (1) stage in which delta13C values vary from +2 to +3.7‰ PDB and average 3‰ PDB, (2) stage with delta13C values displaying stronger oscillations (from -2‰ to +‰ PDB), and (3) stage with an isotopic plateau with values around +3.7‰ PDB. Constant 87Sr/86Sr values (~ 0.70600) characterize C-isotope stage 1, whereas slightly fluctuating values (from 0.70600 to 0.70700)...

Caciques, autoridades fronterizas y lenguaraces: intermediarios culturales e interlocutores válidos en Buenos Aires (primera mitad del siglo XIX)
Provedor de dados: 125
Autores: Ratto,Silvia.
El objetivo de este trabajo es acercarnos al conocimiento de los intermediarios culturales que habitaron el espacio fronterizo bonaerense en la primera mitad del siglo XIX. La elección de este período se fundamenta en que a lo largo del mismo se transitó por una compleja relación interétnica que derivó, a fines de la década de 1820, en la aplicación de una política indígena muy particular por parte del gobierno de Buenos Aires. Esta llevó, por un lado, al asentamiento de grupos nativos dentro del espacio provincial y, por otro, al establecimiento de alianzas con otras agrupaciones. Las cotidianas y constantes relaciones interétnicas que debieron llevarse a cabo a raíz de este proceso, produjeron la aparición de un gran número de personajes "intermediarios".

Cadmium effect on the association of jackbean (Canavalia ensiformis) and arbuscular mycorrhizal fungi
Provedor de dados: 63
Autores: Andrade,Sara Adrián López de; Jorge,Renato Atílio; Silveira,Adriana Parada Dias da.
The effect of cadmium (Cd) on mycorrhizal association and on shoot and root Cd concentration was investigated in jackbean plants under hydroponic conditions. The treatments consisted of the inoculation of three different species of arbuscular mycorrhizal fungi (AMF), Glomus etunicatum, G. intraradices and G. macrocarpum, and a non-inoculated control, two Cd (0 and 5 µmol L-1) and two P (1 and 10 mg L-1) levels in the nutrient solution. Mycorrhizal colonization, length of AMF extraradical mycelium, guaiacol peroxidase activity in roots, plant growth and root and shoot Cd and P concentrations were determined. Mycorrhizal status did not promote jackbean growth but in most of the cases mycorrhization increased root and shoot Cd concentrations. Cd ions were...

Cadmium toxicity in plants
Provedor de dados: 61
Autores: Benavides,María P.; Gallego,Susana M.; Tomaro,María L.
Heavy metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, evolutionary, nutritional, and environmental reasons. Plants posses homeostatic cellular mechanisms to regulate the concentration of metal ions inside the cell to minimize the potential damage that could result from the exposure to nonessential metal ions. This paper summarizes present knowledge in the field of higher plant responses to cadmium, an important environmental pollutant. Knowledge concerning metal toxicity, including mechanisms of cadmium homeostasis, uptake, transport and accumulation are evaluated. The role of the cell wall, the plasma membrane and the mycorrhizas, as the main barriers against cadmium entrance to the...

Cadmium-Zinc interactions in a hydroponic system using Ceratophyllum demersum L.: adaptive ecophysiology, biochemistry and molecular toxicology
Provedor de dados: 61
Autores: Aravind,Parameswaran; Prasad,Majeti Narasimba Vara.
The interaction between an essential micronutrient, Zn and a toxic non-essential element, Cd has been comprehensively reviewed based on our experiments conducted with Ceratophyllum demersum L. in a hydroponic system. Since Cd and Zn belong to the group IIB transition elements and show similarities in chemistry, geochemistry and environmental properties, it would be one of the elemental pairs of choice to investigate metal-metal interactions. Evidence in support of the protective role of Zn against Cd toxicity in Ceratophyllum demersum L. is presented in this review. Based on our experimental results, we conclude that the antioxidant properties of Zn play an important role in counteracting Cd toxicity.

CAIS Program Structure and Performance: Evidence from Ontario
Provedor de dados: 31
Autores: Mussell,   Al; Martin,   Larry J.
The Canadian Agricultural Income Stabilization (CAIS) program was approved in late 2003. It now serves as Canada’s sole farm safety net program, having replaced the Net Income Stabilization Account (NISA), Canadian Farm Income Program (CFIP), and provincial companion programs. However, the mechanisms of operation and actual performance of CAIS in providing stability to farm incomes are relatively unknown. In particular, to develop expectations of future farm costs and returns and to determine their support for CAIS as the sole safety net under the federal-provincial Agricultural Policy Framework (APF), farmers and their representatives need a concrete understanding of how CAIS can be expected to work relative to its predecessors.

ABSTRACT: The sweet passion fruits is a native species of Brazil. It is very well adapted to tropical regions, and can be found growing in wild conditions or cultivated by small farmers in many regions. It is consumed mainly as a fresh fruit, splitting with a knife in two parts and using a spoon to collect the pulp with the seeds. The concentrated juice, easily extracted from the pulp, can be used to make juice, ice-cream and deserts. Many small farmers grow sweet passion fruit as an ornamental plant, particularly because of the beauty flowers and colored fruits. In additon it is considered as a medicinal species to treat stress, anxiety and sleeplessness. The ofter of fresh sweet passion fruit in most fruit and grocery stores is still very limited, and...

Calagem em solos de várzea e a disponibilidade de nutrientes na solução do solo após o alagamento
Provedor de dados: 65
Autores: Silva,Leandro Souza da; Ranno,Sidnei Küster.
A calagem do solo altera o pH e, conseqüentemente, influencia no processo de redução dos solos submetidos ao alagamento para o cultivo do arroz irrigado, alterando a disponibilidade de nutrientes na solução do solo. Entretanto, a recomendação de calcário para o arroz irrigado é variável, implicando em diferentes quantidades a aplicar, dependendo da situação. Assim, o objetivo deste trabalho foi avaliar a liberação de nutrientes para a solução do solo após o alagamento, em três solos de várzea com diferentes valores de pH, resultantes da aplicação de diferentes quantidades de calcário. Amostras de solos de várzea foram coletadas da camada de 0 a 20 cm em áreas de produção de arroz nos municípios de Cachoeirinha/RS (Gleissolo), Faxinal do Soturno (Planossolo...

Autores: Kanwar,   Ramesh S.; Reungsang,   Pipat; Jha,   Manoj K.; Gassman,   Philip W.; Ahmad,   Khalil; Saleh,   Ali.
A validation study has been performed using the Soil and Water Assessment Tool (SWAT) model with data collected for the Upper Maquoketa River Watershed (UMRW), which drains over 16,000 ha in northeast Iowa. This validation assessment builds on a previous study with nested modeling for the UMRW that required both the Agricultural Policy EXtender (APEX) model and SWAT. In the nested modeling approach, edge-of-field flows and pollutant load estimates were generated for manure application fields with APEX and were then subsequently routed to the watershed outlet in SWAT, along with flows and pollutant loadings estimated for the rest of the watershed routed to the watershed outlet. In the current study, the entire UMRW cropland area was simulated in SWAT, which...

Calor específico e densidade da polpa de cajá (Spondias lutea L.) com diferentes concentrações de sólidos solúveis sob baixas temperaturas
Provedor de dados: 70
Autores: Mata,Mario E. R. M. Cavalcanti; Duarte,; Zanini,Helen L. H. T.
A polpa de cajá tem sido exportada da região Nordeste para todo o Brasil, e uma das maneiras de conservá-la é processando-a e armazenado-a na forma congelada. Durante o processamento, existem dois fatores que favorecem a qualidade do produto a ser armazenado: a rapidez com que o produto é congelado e a adição de açúcar como forma de dificultar a ação microbiológica. Na linha de processo, algumas propriedades termofísicas, como o calor específico e a densidade, se alteram com as temperaturas negativas e com o teor de sólidos solúveis totais; dessa forma, para o dimensionamento adequado de máquinas e equipamentos, torna-se necessário conhecer essas propriedades, principalmente quando se operam equipamentos criogênicos, onde as temperaturas podem chegar a...

Autores: Martínez, S.; Acosta, A.
Several predictions have been made, about magnitude and direction of temporal changes in the coral community structure, during the last decade. However, few studies have demonstrated it quantitatively. In order to document such changes, the coral community structure was studied in four continental reefs in the Colombian Caribbean, two in the Santa Marta region: Punta Betín (PB) and Morro Grande Island (MO), and two in the Tayrona National Natural Park (PNNT): Granate cove (GR) and Gayraca bay (GA). Coral composition and cover were quantified in 2002 and compared to base line studies from 1989 (PB, MO &amp; GR) and from 1992 (GA). These variables were quantified by 20 m linear transects between 1.5 m and 29 m depth. After a decade, all reefs lost in average...

CaMKIIdelta overexpression in hypertrophy and heart failure: cellular consequences for excitation-contraction coupling
Provedor de dados: 56
Autores: Maier,L.S.
Ca/calmodulin-dependent protein kinase IIdelta (CaMKIIdelta) is the predominant isoform in the heart. During excitation-contraction coupling (ECC) CaMKII phosphorylates several Ca-handling proteins including ryanodine receptors (RyR), phospholamban, and L-type Ca channels. CaMKII expression and activity have been shown to correlate positively with impaired ejection fraction in the myocardium of patients with heart failure and CaMKII has been proposed to be a possible compensatory mechanism to keep hearts from complete failure. However, in addition to these acute effects on ECC, CaMKII was shown to be involved in hypertrophic signaling, termed excitation-transcription coupling (ETC). Thus, animal models have shown that overexpression of nuclear isoform...

Can a peach production in organic farming be requalified with polyphenols ?   A comparative case study in Rhone-Alpes Region (France)
Provedor de dados: 21
Autores: Fauriel, Joël; Bellon, Stéphane; Plénet, Daniel; Amiot, Marie-Jo.
Peach production in the Rhône-Alps region is increasingly challenged by mediterranean European regions. A possible regional strategy would consist in the development of qualification signs. A significant part of the peach production is already labelled (CCP, Red Label, Organic). How such labels relate with quality attributes at field level ? Can polyphenols be considered as an asset in a re-qualification process of peach production?     To contribute to these issues, we present preliminary results derived from field work in Rhône-Alps. The study was conducted on 12 orchards of yellow peach (cv Spring Lady) in farms. 10 orchards were managed according to the above mentioned specifications while 2 were cultivated without specifications.

Can a Warmer Climate Save Northern Agriculture?
Provedor de dados: 31
Autores: Gaasland,   Ivar.
Agriculture at high latitudes is expected to be a main beneficiary of a man-made climate change. A numerical model, using Norway as a case, is employed to analyze the impacts of a warmer climate on northern agriculture. The computations indicate that the current degree of self-sufficiency can be achieved with less budget support and higher economic welfare. However, it may be argued that environmental goods, such as landscape and biodiversity preservation, and rural settlement, are more important than self-sufficiency for northern agriculture. It is demonstrated that, in that case, welfare gains are substantially lower, and can even be negative.

Can Calibration Reconcile Stated and Observed Preferences?
Provedor de dados: 31
Autores: Norwood,   F. Bailey.
Hypothetical bias is a pervasive problem in stated-preference experiments.  Recent research has developed two empirically successful calibrations to remove hypothetical bias, though the calibrations have not been tested using the same data or in a conjoint analysis.  This study compares the two calibrations in a conjoint analysis involving donations to a public good.  Results find the calibrations are biased predictors of true donations but that calibrated and uncalibrated models together provide upper and lower bounds to true donations.

Can cross-reactivity studies enable generic allergy prevention?
Provedor de dados: 26
Autores: Sánchez-Monge, R.; Salcedo, G.
The occurrence of homologous proteins in foods, pollen and latex is the molecular basis of the plant sources’ allergenic cross-reactivity. However, there is not a generic cross-reactivity. Each allergic patient is sensitized to particular allergens and even to particular IgE-binding epitopes. Molecular studies on the main panallergens may explain the major plant-food, pollen and latex syndromes. Some examples of the bestcharacterized plant panallergens are presented. Novel technologies on recombinant proteins and microarrayed allergens will provide allergen-sensitization profiles, associated to food allergies and cross-reactivity, that will enable the diagnosis and prediction of cross-reactions as well as individual treatment of these pathologies.

Can Forest Management Strategies Sustain The Development Needs Of The Little Red River Cree First Nation?
Provedor de dados: 31
Autores: Krcmar,   Emina; Nelson,   Harry; van Kooten,   G. Cornelis; Vertinsky,   Ilan; Webb,   Jim.
In this study, we explore whether projected socio-economic needs of the Little Red River Cree Nation (LRRCN) can be met using the natural resources to which they have access. To answer this question, we employ a dynamic optimization model to assess the capacity of the available forest base to provide for anticipated future needs of the LRRCN. Results for alternative management strategies indicate that decision-makers face significant tradeoffs in deciding an appropriate management strategy for the forestlands they control.

Can Local Ecological Knowledge Contribute to Wildlife Management? Case Studies of Migratory Birds
Provedor de dados: 7
Autores: Gilchrist, Grant; ; grant.gilchrist@ec.gc.ca; Mallory, Mark; ; mark.mallory@ec.gc.ca; Merkel, Flemming; ;.
Sound management of wildlife species, particularly those that are harvested, requires extensive information on their natural history and demography. For many global wildlife populations, however, insufficient scientific information exists, and alternative data sources may need to be considered in management decisions. In some circumstances, local ecological knowledge (LEK) can serve as a useful, complementary data source, and may be particularly valuable when managing wildlife populations that occur in remote locations inhabited by indigenous peoples. Although several published papers discuss the general benefits of LEK, few attempt to examine the reliability of information generated through this approach. We review four case studies of marine birds in...

Tropical deforestation can cause fundamental regional-scale shifts in vegetation structure and diversity. This is particularly true in Africa. Although national parks are being established to protect areas from deforestation and to conserve biodiversity, these parks are not immune to disturbances outside their boundaries. We used regional-scale atmospheric simulation experiments to investigate how deforestation in timber concessions might affect precipitation inside adjacent, undisturbed national parks in the equatorial African countries of Gabon and the Republic of Congo. The experiments revealed a complex response. Some parks showed rainfall reduced as much as 15%, while others showed slight increases. Rainfall inside parks was particularly sensitive to...

Can Multiyear Rollover Hedging Increase Mean Returns?
Provedor de dados: 31
Autores: Yoon,   Byung-Sam; Brorsen,   B. Wade.
Both market advisors and researchers have often suggested multiyear rollover hedging as a way to increase producer returns.  This study determines whether rollover hedging can increase expected returns for producers.  For rollover hedging to increase expected returns, futures prices must follow a mean-reverting process.  To test for the existence of mean reversion in agricultural commodity prices, this study uses a longer set of price data and a wider range of test procedures than past research.  With the use of both the return predictability test from long-horizon regression and the variance ratio test, we find that mean reversion does not exist in futures prices for corn, wheat, soybean, soybean oil, and soybean meal.  The findings are consistent with...

Can organic and transgenic soy be used as a substitute for animal protein by rats?
Provedor de dados: 56
Autores: Soares,L.L.; Lucas,A.M.M.; Boaventura,G.T.
We evaluated the protein quality of organic and transgenic soy fed to rats throughout life. Thirty female Wistar rats were divided into three groups (N = 10): organic soy group (OSG) receiving organic soy-based diet, genetically modified soy group (GMSG) receiving transgenic soy-based diet, and a control group (CG) receiving casein-based diet. All animals received water and isocaloric diet (10% protein), ad libitum for 291 days. After this, the weight of GMSG animals (290.9 ± 9.1 g) was significantly lower (P &lt;= 0.04) than CG (323.2 ± 7.9 g). The weight of OSG (302.2 ± 8.7 g) was between that of the GMSG and the CG. Protein intake was similar for OSG (308.4 ± 6.8 g) and GMSG (301.5 ± 2.5 g), and significantly lower (P &lt;= 0.0005) than the CG (358.4 ±...

Can Rank-Order Tournaments Improve Efficiency of Quality Differentiated Crop Markets Under Marketing Loan Program Operation?  The Case of U.S. Peanuts.
Provedor de dados: 31
Autores: Nadolnyak,   Denis A.; Fletcher,   Stanley M.; Revoredo-Giha,   Cesar.
In the paper, alternative contractual arrangements between crop producers and processors are evaluated with a view of addressing the major issues present in peanut markets in the U.S., the major EU supplier of high quality peanuts. The issues are the thinness of the spot markets and the absence of quality premiums, both of which impair market efficiency. Results indicate that introducing contracts with a system of quality differentials creates incentives for producer self-selection to participate in the post harvest cash market. Moreover, in the presence of  sufficiently high common production risk, tournament contracts are more efficient and preferred by the producers than the standard fixed premium schedules.

Can Risk Reducing Policies Reduce Farmer's Risk and Improve Their Welfare?
Provedor de dados: 31
Autores: Anton,   Jesus; Giner,   Celine.
This paper develops an analytical model able to represent the decisions of an individual risk averse farmer facing variability in both prices and yields. A comprehensive set of stylised risk reducing policy measures is represented. A calibration of the model is used to run Monte-Carlo simulations and to obtain optimal responses. The main focus is the interaction between policy measures and market strategies in terms of impacts on production, welfare and risk. Risk reducing strategies that cover different sources of risk, such as price and yield variability, may be complementary for the farmers. Counter-cyclical area payments create incentives to bring land into production and their capacity to reduce farming risk is mitigated by the potential crowding out...

Can the Value of Ecosystem Services Pay for the Conservation of the World’s Remaining Tropical Rainforests?
Provedor de dados: 31
Autores: Brand,   David.
Deforestation continues at a significant rate, especially in developing tropical countries. The process is a consequence of pressures to realise the commercial value of the timber and/or the land, the latter typically for either agriculture or settlement. Forests are integral to a variety of increasingly valuable environmental systems — carbon, water and biodiversity. Measures such as stopping illegal logging, and labelling logs from sustainablymanaged forests, are important palliatives. However, the real need is to develop price signals that reflect the substantial value of environmental services, and to integrate these into the international commodity economy.

Can U.S. Farm Subsidies Be Bought Out?
Provedor de dados: 31
Autores: Orden,   David.
Achieving substantial agricultural trade liberalization has proven elusive in the Doha Round. This paper examines policy reforms the United States might adopt to facilitate progress. The focus is on whether decoupling can be made more convincing through a long-term buyout that would end farm subsidies. Buyouts have not been feasible in the past but recent reforms for several specialty crops provide evidence of what might be done and the conditions under which it occurs. Although the political-economy conditions may not be conducive to such a buyout yet, estimates are provided of the potential cost of a buyout of the main U.S. farm support subsidies of direct fixed and counter-cyclical payments.

Can we detect the effects of environmental variations on fish populations through VPA outputs? the North Atlantic albacore case
Provedor de dados: 5
Autores: Kell, Laurence T; Fromentin, Jean-marc; Ortiz De Zarate, Victoria; Arrizabalaga, Haritz.
Past studies have indicated that numbers-at-age 1 of albacore may be correlated with the winter NAO index in the previous year. Two main hypotheses have been stressed to explain such observation, i.e. an impact of the NAO on the recruitment or on migration patterns and consequently in the availability and catchability of specific age classes to the surface fishery. The objective of the present paper is to test whether such processes can be distinguished using VPA outputs. We first computed simple cross-correlations between the NAO at various lags, catches-at-age, Numbers-atage and F-at-age estimated in the last assessment. Since results were inconclusive, simulations were undertaken. The results showed that the probability of detecting spurious...

Canada-US Softwood Lumber Trade Revisited: Examining the Role of Substitution Bias in the Context of a Spatial Price Equilibrium Framework
Provedor de dados: 31
Autores: Mogus,   Anthony; Stennes,   Brad; van Kooten,   G. Cornelis.
In the last two decades, softwood lumber trade between Canada and the United States has been characterized by numerous trade restrictions. Many studies have attempted to quantify the effects of such sanctions, and in doing so, softwood lumber was modeled as a single, homogenous commodity. However, recent research has suggested that this may be a misleading assumption, since not all softwood lumber products are equivalent substitutes. We refer to this problem as the substitution bias, and uniquely address this issue in estimating the effects of trade restricting policies. Using a spatial price equilibrium (spe) model, impacts of the post-sla import duties are estimated and compared to estimates of two alternative policy regimes – an export tax and quota. By...

Canadian Farmers' Adaptation to Declining Commodity Prices
Provedor de dados: 31
Autores: Painter,   Marvin J.
The five major agricultural producing provinces are compared in terms of farm labour and management incomes, return on investment to farm capital, total farm family income, and farm family net worth. In each province, comparisons are made with non-farm incomes, investment returns and net worth levels. The results show that farm family incomes in Canada are much better today than 30 years ago, returns on farmland investment are very comparable to average stock market returns, and average farm family net worth is significantly higher than the average for all families. The conclusion is that Canadian farmers have adapted well to declining commodity prices mainly by being adapters of and investors in new technologies, allowing them to increase farm size...

Autores: Borresch,   Rene; Kavallari,   Aikaterini; Schmitz,   P. Michael.
In the previous years the Mediterranean Member States of the EU came across the Reform of the CAP and especially last year faced the second wave of the Reform for three typical Mediterranean products, namely cotton, olive oil and tobacco. In this paper a partial equilibrium model is used to simulate the impacts of decoupling, as a key point of the decided CAP Reform. The second wave of the Reform appears to be of crucial importance for the southern EU countries and although the producer's income is reduced, there are positive welfare effects.

CAP Reform in the Light of the WTO Doha Round Negotiations
Provedor de dados: 31
Autores: Halmai,   Peter; Elekes,   Andrea.
Our paper focuses on the question: how the measures of June 2003 agreement can help the EU to meet the new WTO commitments. As decoupling of direct payments and WTO classification of the new payments seem to be one of the most important questions from the point of view of WTO negotiations, our analysis focuses mainly on the Single Farm Payment (SFP). We assesses the decoupled nature of the single farm payment (SFP) based on WTO and OECD criteria. We conclude that the SFP meets not only the current WTO (design based) criteria of decoupling, but can also be qualified as effective fully decoupled system using the OECD terminology.

Capacity and scale inefficiency: Application of data envelopment analysis in the case of the french seaweed fleet
Provedor de dados: 5
Autores: Guyader, Olivier; Daures, Fabienne.
Data Envelopment Analysis (DEA) models are applied to the main French seaweed fleet to examine capacity output, capacity utilization, and scale inefficiency. Coastal seaweed vessels target only one output - kelp - with the same gear but with different input level combinations. The fishery is seasonal and subject mainly to input regulations, especially a one trip per day regulation implemented in 1987. The consequence was a decline in total observed output and a fall in capacity output and efficient output. Only the largest vessels and a few small vessels harvesting without this regulatory constraint operate at the optimal scale. The question of a change in regulation, especially a shift to an individual quota system, is raised.

Captura de enxames de abelhas sem ferrão (Hymenoptera, Apidae, Meliponinae) sem destruição de árvores
Provedor de dados: 36
Autores: Coletto-Silva,Alexandre.
No Brasil a criação racional de abelhas sem ferrão é denominada meliponicultura. As abelhas sem ferrão possuem diferentes comportamentos de nidificação, com ninhos internos (cavidades naturais ou não) e externos. Um dos principais problemas apresentados na meliponicultura é a captura de uma colônia com o objetivo de iniciar um meliponário sem "destruir as árvores" ou mesmo as próprias colônias durante a captura. O presente trabalho apresenta um método alternativo para captura de colônias de abelhas sem ferrão, especialmente, do gênero Melipona Illiger, 1806, que são as espécies mais utilizadas para produção de mel e pólen, na região Amazônica. O método consiste em abrir uma janela na árvore, coletar o material e fechar a abertura utilizando a resina...

Carabid beetles (Carabidae) in agroecosystems - case study on the effects of conversion to organic farming and land structure
Provedor de dados: 21
Autores: Sarapatka, Bořivoj; Vesely, Milan.
Our research compared the effects of farming systems (conventional, conversion to organic farming, resp. organic farming) and land structures (ecotones) on carabid beetles in four experimental plots during a five-year crop rotation cycle. An important factor affecting the composition of carabid communities was the type of land fragmentation contributing to a faster colonization of fields from ecotones. The factor of agricultural management, organic farming, was also significant. In the final years of the experiment we noted changes in the species composition of the carabid communities compared with the first years of the experiment, with an increase in the preference of bigger carabid species. The abundance of large carabid species was much lower in...

Autores: Silva,Andréia Cristina; Ferreira,Lino Roberto; Silva,Antônio Alberto da; Belo,Alessandra Ferreira; Sediyama,Carlos Sigueyuki.
A degradação das pastagens é um dos maiores problemas da pecuária, afetando diretamente a sustentabilidade do setor. Como alternativas de recuperação, tem sido proposta a utilização de culturas anuais em consórcio com forrageiras. No entanto, para a viabilização do consórcio, é necessário o manejo adequado da forrageira minimizando a competição com a cultura. Objetivou-se, neste trabalho, avaliar os efeitos da aplicação do fluazifop-p-butil em caracteres morfológicos de Brachiaria brizantha e soja, cultivadas em consórcio. O experimento foi realizado em Coimbra-MG. Foram avaliadas seis doses de fluazifop-p-butil (0, 18, 36, 54, 72 e 90g ha-1) aplicadas em duas épocas (21 e 28 dias após a emergência da soja - DAE) e 2 testemunhas (soja e braquiária em...

Características fisiológicas e ecológicas de isolados de rizóbios oriundos de solos ácidos de Iranduba, Amazonas
Provedor de dados: 86
Autores: Hara,Francisco Adilson dos Santos; Oliveira,Luiz Antonio de.
O alumínio e a acidez dos solos da Amazônia podem diminuir a população de rizóbios que fixam o nitrogênio, solubilizam fosfatos pouco solúveis e aumentam a disponibilidade do fósforo em sistemas produtivos. O objetivo deste trabalho foi avaliar a capacidade nodulífera, tolerância à acidez e ao alumínio, bem como a capacidade de solubilizar fosfatos insolúveis de isolados de rizóbios, obtidos de amostras de solos agrícolas do Município de Iranduba, AM. As amostras de solos apresentavam isolados de rizóbios com potencialidades para serem utilizados como fonte de inóculos para o caupi, de cujos nódulos foram extraídos para testes de tolerância e solubilização. O inóculo INPA-M10 tendeu a superar todos os demais quanto ao rendimento da biomassa seca da parte...

Um dos requisitos básicos para obtenção de sucesso no controle dessa doença é o conhecimento do patógeno, especialmente de fatores relacionados à fisiologia e biologia. O presente trabalho teve como objetivo caracterizar cinco isolados de S. rolfsii, obtidos de pimentão, quanto ao crescimento micelial, produção de escleródios em diferentes regimes de luminosidade e em seis substratos naturais e a compatibilidade vegetativa entre os isolados. O efeito do substrato variou com o isolado na produção de escleródios. Os isolados SR3 e SR5 apresentaram maior produção de escleródios nos substratos aveia-ágar...

Caracterização de estirpes de Ralstonia solanacearum isoladas de plantas de batata com murcha bacteriana, por PCR-Rep e RAPD
Provedor de dados: 102
Autores: Silveira,José R. P.; Duarte,Valmir; Moraes,Marcelo G.; Oliveira,Andréia M. R.; Barni,Valmor; Maciel,João L. N.
Considerado como um dos mais sérios patógenos da batata (Solanum tuberosum), em regiões de clima tropical, subtropical, assim como em zonas mais quentes de clima temperado, Ralstonia solanacearum é uma espécie com significativa diversidade genética. Ela é caracterizada em um sistema binário de raças e biovares, com base nas espécies hospedeiras e na capacidade de utilizar diferentes fontes de carbono. A tentativa de utilizar a resistência genética como forma de controle de R. solanacearum não tem demonstrado estabilidade, devido a alterações climáticas nas diferentes regiões e a variabilidade das estirpes do patógeno. Devido às características epidemiológicas diferentes para essas biovares, estirpes da biovar 2 são mais factíveis de serem erradicadas em um...

Autores: Meletti,Laura Maria Molina; Soares-Scott,Marta Dias; Bernacci,Luís Carlos.
O interesse pelo cultivo do maracujazeiro-roxo vem crescendo no centro-sul do País, visando à exportação. Observa-se um número significativo de formas selvagens, nativas, compatíveis entre si, propagadas por sementes de polinização aberta, ampliando a variabilidade natural da fruteira. Com o objetivo de identificar cruzamentos com características comerciais desejáveis e disponibilizar sementes de matrizes selecionadas aos produtores, foram realizados estudos de caracterização agronômica, morfológica e citogenética, envolvendo seleções do Banco de Germoplasma de Passifloras do IAC, denominadas 'Roxinho-Miúdo', 'Paulista' e 'Maracujá-Maçã'. Durante duas safras consecutivas, foram analisados cerca de 350 flores e 150 frutos de cada seleção. A maior amplitude...

Caracterización del gobierno de Gutiérrez y perfil del gobierno de Palacio (Actualidad: Perspectivas)
Provedor de dados: 122
Autores: Borja, Raúl.
Desde su génesis, el gobierno de Gutiérrez fue un ensayo “a la criolla” de instauración de un régimen de tipo “bonapartista”. El bonapartismo es una categoría de análisis político construida por Marx en su obra “El 18 Brumario de Luis Bonaparte” (1852), útil para interpretar el carácter de ciertos regímenes de transición que encarnan una alianza de clases emergentes. El bonapartismo es una forma de gobierno que deviene régimen totalitario gracias a la deslegitimación al poder legislativo. Generalmente los gobiernos bonapartistas son liderados por un individuo “que se coloca como el representante directo de la Nación, el garante del orden público, el árbitro imparcial frente a los intereses contrapuestos de las clases”.

Carbon Dioxide Capture and Storage (CCS) - Liability for Non-Permanence under the UNFCCC
Provedor de dados: 31
Autores: Bode,   Sven; Jung,   Martina.
Prior to CoP 10, our discussion paper "On the Integration of Carbon Capture and Storage into the International Climate Regime" argued that carbon capture and storage (CCS) was similar to carbon sequestration in the area of Land Use, Land-Use Change and Forestry (LULUCF). This was criticized by several readers who observed that treating CCS as a removal activity (sink) would not be compatible with the UNFCCC sink definition, what we already had mentioned in the paper. The present paper is based on the UNFCCC definition and analyses how CCS could be integrated into the climate regime. As CO2 may re-enter the atmosphere after injection into geological reservoirs, the question of long-term liability has to be considered. Apart from this aspect, additional...

Leaves of Artemisia annua L. are a plentiful source of artemisinin, a drug with proven effectiveness against malaria. The aim of this study was to classify the photosynthetic mechanism of A. annua through studies of the carbon isotope composition (delta 13C) and the leaf anatomy. A. annua presented a delta 13C value of - 31.76 ± 0.07, which characterizes the plants as a typical species of the C3 photosynthethic mechanism, considering that the average delta 13C values for C3 and C4 species are -28 and -14, respectively. The leaf anatomy studies were consistent with the delta 13C results, where, in spite of the existence of parenchymatic cells forming a sheath surrounding the vascular tissue, the cells do not contain chloroplasts or starch. This...

Carbon Mitigation Costs for the Commercial Sector: Discrete-Continuous Choice Analysis of Multifuel Energy Demand
Provedor de dados: 31
Autores: Newell,   Richard G.; Pizer,   William A.
We estimate a carbon mitigation cost curve for the U.S. commercial sector based on econometric estimation of the responsiveness of fuel demand and equipment choices to energy price changes. The model econometrically estimates fuel demand conditional on fuel choice, which is characterized by a multinomial logit model. Separate estimation of end uses (e.g., heating, cooking) using the 1995 Commercial Buildings Energy Consumption Survey allows for exceptionally detailed estimation of price responsiveness disaggregated by end use and fuel type. We then construct aggregate long-run elasticities, by fuel type, through a series of simulations; own-price elasticities range from -0.9 for district heat services to -2.9 for fuel oil. The simulations form the basis of...

Carbon Sequestration in Agricultural Soils: Discounting for Uncertainty
Provedor de dados: 31
Autores: Kurkalova,   Lyubov A.
The study presents a conceptual model of an aggregator who selectively pays farmers for altering farming practices in exchange for carbon offsets that the change in practices generates. Under the assumption that the offsets are stochastic and that the aggregator maximizes the sum of the offsets from the purchase that he/she can rightfully claim with a specified level of confidence subject to a budget constraint, we investigate the optimal discounting of expected carbon offsets. We use the model to estimate empirically the optimal discounting levels and costs for a hypothetical carbon purchasing project in the Upper Iowa River Basin.

In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government run conservation programs that are designed to promote a broad array of environmental attributes (both carbon sequestration and its co-benefits) for the supply of carbon. Finally, policy design and efficiency issues associated with the potential interplay between a private carbon market and a government conservation program are studied. Empirical analyses for an area that represents a significant potential source of carbon sequestration and...

Carbon sequestration potential for irrigated grazing lands is significant. We measured organic and  inorganic C stored in southern Idaho soils having long-term land use histories that supported native sagebrush  vegetation (NSB), irrigated pasture systems (IP), irrigated conservation tillage sites (ICT), and irrigated  moldboard plowing systems (IMP). This study estimates the amount of possible organic, inorganic and total C  sequestration if irrigated pasture land was expanded by 10%.

Carbon Sinks and Reservoirs: The Value of Permanence and Role of Discounting
Provedor de dados: 31
Autores: Benitez,   Pablo C.; van Kooten,   G. Cornelis.
Scientists are enthusiastic about storing carbon in terrestrial sinks and geological reservoirs in order to obviate the need for lifestyle-changing reductions in fossil-fuel use. Estimating relative costs of various options depends on how permanence is assessed and whether physical carbon is discounted. We demonstrate that, in carbon markets, terrestrial sinks credits cannot be traded one-for-one for emission reduction credits and the conversion factor would depend on how long sinks keep CO2 out of the atmosphere as compared with emission reductions and, discounting physical carbon. As a result, the authority could not determine a conversion factor and the market would be required to do so.

Carbon sources and polyethylene glycol on soybean somatic embryo conversion
Provedor de dados: 86
Autores: Körbes,Ana Paula; Droste,Annette.
Somatic embryogenesis is an efficient method for the production of target cells for soybean genetic transformation. However, this method still offers low percentages of plant regeneration, and perhaps is related to the maturation process and high morphological abnormalities of the matured embryos. This study aimed to identify a maturation medium that could contribute to the outcome of more efficient plant regeneration results. Embryogenic clusters, derived from cotyledons of immature seeds of the soybean cultivars Bragg and IAS5, were used as starting material for embryos development. Different maturation media were tested by using 6% maltose, 3% sucrose or 6% sucrose, combined with or without 25 g L-1 of the osmotic regulator polyethylene glycol...

Carbonate cements in contemporaneous beachrocks, Jaguaribe beach, Itamaracá island, northeastern Brazil: petrographic, geochemical and isotopic aspects
Provedor de dados: 42
Autores: Guerra,Núbia C.; Kiang,Chang H.; Sial,Alcides N.
Holocene beachrocks of the Jaguaribe beach, State of Pernambuco, northeastern Brazil, consist of horizontal, cemented layers approximately 40 cm thick. The cement shows three textural varieties: (a) calciferous, surrounding siliciclastic grains, (b) micritic, with an acicular fringe; and (c) cryptocrystalline calcite in pores. Early cementation took place at the water table below beach ridges, where geochemical, hydrodynamic and, perhaps, also microbiological conditions favored rapid precipitation of aragonite and/or high-Mg calcite. delta13C values range from -1.8 to +1.5‰ for dissolved carbonate in interstitial water and from +0.2 to +2.1‰ for bioclastic components. delta18O values range from -2.8 to +0.5‰ for seawater, freshwater and interstitial water....

This study evaluated the use of different probiotics, prebiotics and symbiotics on the quality of carcasses and meat of broiler chickens. One hundred and eight day-old Cobb male broilers were used (n=108) in a completely randomized design according to a 3x3 factorial, with 3 probiotics in the diet (no probiotics, probiotics 1, probiotics 2) and 3 prebiotics in the diet (no prebiotics, prebiotics 1, prebiotics 2). There were nine treatments with 4 replicates and 3 birds per replicate. The results showed that the carcass and cut yields, color (L* - lightness, a* - redness, and b* - yellowness), pH, cooking losses, shearing force and sensory analysis were not affected by the use of different growth promoters at 42 days of age. It was concluded that growth...

Cardiac preload and venous return in swimming sea bass (Dicentrarchus labrax L.)
Provedor de dados: 5
Autores: Sandblom, Erik; Farrell, Anthony; Altimiras, Jordi; Axelsson, Michael; Claireaux, Guy.
Cardiac preload (central venous; pressure, Pcv), mean circulatory filling pressure (MCFP), dorsal aortic blood pressure (P-DA) and relative cardiac output (Q) were measured in sea bass (Dicentrarchus labrax) at rest and while swimming at 1 and 2 BL s(-1). MCFP, an index of venous capacitance and the upstream venous pressure driving the return of venous blood to the heart, was measured as the plateau in Pcv during ventral aortic occlusion. Compared with resting values, swimming at 1 and 2BL s(-1) increased Q (by 15 +/- 1.5 and 38 +/- 6.5%, respectively), Pcv (from 0.11 +/- 0.01 kPa to 0.12 +/- 0.01 and 0.16 +/- 0.02 kPa, respectively), MCFP (from 0.27 +/- 0.02 kPa to 0.31 +/- 0.02 and 0.40 +/- 0.04 kPa, respectively) and the calculated pressure gradient for...

The pharmacokinetics of propranolol may be altered by hypothermic cardiopulmonary bypass (CPB), resulting in unpredictable postoperative hemodynamic responses to usual doses. The objective of the present study was to investigate the pharmacokinetics of propranolol in patients undergoing coronary artery bypass grafting (CABG) by CPB under moderate hypothermia. We evaluated 11 patients, 4 women and 7 men (mean age 57 ± 8 years, mean weight 75.4 ± 11.9 kg and mean body surface area 1.83 ± 0.19 m²), receiving propranolol before surgery (80-240 mg a day) and postoperatively (10 mg a day). Plasma propranolol levels were measured before and after CPB by high-performance liquid chromatography. Pharmacokinetic Solutions 2.0 software was used to estimate the...

Cardiovascular actions of angiotensin-(1-7)
Provedor de dados: 56
Autores: Ferreira,A.J.; Santos,R.A.S.
Angiotensin-(1-7) (Ang-(1-7)) is now considered to be a biologically active member of the renin-angiotensin system. The functions of Ang-(1-7) are often opposite to those attributed to the main effector component of the renin-angiotensin system, Ang II. Chronic administration of angiotensin-converting enzyme inhibitors (ACEI) increases 10- to 25-fold the plasma levels of this peptide, suggesting that part of the beneficial effects of ACEI could be mediated by Ang-(1-7). Ang-(1-7) can be formed from Ang II or directly from Ang I. Other enzymatic pathways for Ang-(1-7) generation have been recently described involving the novel ACE homologue ACE2. This enzyme can form Ang-(1-7) from Ang II or less efficiently by the hydrolysis of Ang I to Ang-(1-9) with...

Cardiovascular and ventilatory acclimatization induced by chronic intermittent hypoxia: A role for the carotid body in the pathophysiology of sleep apnea
Provedor de dados: 48
Autores: ITURRIAGA,RODRIGO; REY,SERGIO; DEL RÍO,RODRIGO.
Patients with obstructive sleep apnea (OSA) show augmented ventilatory, sympathetic and cardiovascular responses to hypoxia. The facilitatory effect of chronic intermittent hypoxia (CIH) on the hypoxic ventilatory response has been attributed to a potentiation of the carotid body (CB) chemosensory response to hypoxia. However, it is a matter of debate whether the effects induced by CIH on ventilatory responses to hypoxia are due to an enhanced CB activity. Recently, we studied the effects of short cyclic hypoxic episodes on cat cardiorespiratory reflexes, heart rate variability, and CB chemosensory activity. Cats were exposed to cyclic hypoxic episodes repeated during 8 hours for 4 days. Our results showed that CIH selectively enhanced ventilatory and...

Autores: Weber,Oscarlina Lucia dos Santos; Chitolina,José Carlos; Camargo,Otávio Antonio de; Alleoni,Luis Reynaldo Ferracciu.
Os solos tropicais altamente intemperizados apresentam teor significativo de colóides com carga elétrica variável. Entretanto, são poucas as referências em relação à quantificação destas cargas, principalmente em solos ácricos, que representam o extremo na escala de intemperismo. Neste estudo, foram determinadas as cargas permanentes e as variáveis de dois Latossolos Vermelhos acriférricos, um Latossolo Amarelo ácrico e um Latossolo Amarelo acriférrico, que foram comparados a um Nitossolo Vermelho eutroférrico, com carga predominantemente permanente. As amostras foram investigadas pelo método da adsorção do íon césio (Cs+), que mede a carga estrutural permanente (sigmao) e baseia-se na preferência do Cs+ sobre o Li+ na superfície da siloxana de grupos de...

Caring Dairy: A Sustainable Dairy Farming Initiative in Europe
Provedor de dados: 31
Autores: van Calker,   Klaas Jan; Antink,   Rudi H.J. Hooch; Beldman,   Alfons C.G.; Mauser,   Anniek.
Interest in the concept of sustainability in dairy farming has grown as a result of the continuous pressure on farm incomes, occurrence of animal diseases with a major impact on the image of dairy farming, concerns about animal welfare, and environmental problems caused by agriculture. There are, however, still many gaps in the knowledge regarding sustainable dairy farming. Respecting the earth and the environment and "giving back to community" is a fully integrated part of the Mission Statement of ice cream maker Ben &amp; Jerry's. Following this mission, they have initiated a sustainable dairy farming project, "Caring Dairy", for the European production based in the Netherlands. The aim of Caring Dairy is to secure dairy production in a more sustainable...

Cartel Pricing with Entry: the Experience of the Far West Marketing Order for Spearmint
Provedor de dados: 31
Autores: Balagtas,   Joseph Valdes; Masters,   William J.; Zimmer,   Timothy.
This paper documents the remarkable experience of the Far West mint producers in the operation of their marketing order.  From 1993 to 2002, the marketing order witnessed a dramatic reduction its share of the Scotch spearmint market, as well as a reduction in both its price.   We apply a model of a cartel facing a competitive fringe to describe the fall in the marketing order price as a logical consequence of increased world production of spearmint oil.  We estimate an econometric model of the marketing order price and find that a 1-percent change in the marketing order's market share corresponds to a 0.8 percent change in the marketing order price.

Cashew (Anacardium occidentale) is a medicinal plant native to Brazil and also yields a nutritious fruit juice. Its large pulpy pseudo-fruit, referred to as the cashew apple, contains high concentrations of vitamin C, carotenoids, phenolic compounds and minerals. Natural and processed cashew apple juice (CAJ/cajuina) are amongst the most popular juices in Brazil, especially in the north-east. Both juices have antioxidant potential and suppress mutagenicity of hydrogen peroxide. In the present study we evaluated the inhibitory effects of CAJ/cajuina on Aflatoxin B1(AFB1)-induced mutation, using the Salmonella/microsome assay with the experimental approaches of pre-, co- and post-treatments. Both CAJ/cajuina suppress AFB1-induced mutagenesis in strain TA102...

Provedor de dados: 104
Autores: Arzua,Márcia; Onofrio,Valeria C.; Barros-Battesti,Darci M.
The tick collection of the Museu de Historia Natural Capão da Imbuia was first sorted in the end of the 80's, and a list of specimens was published in 1992. During the last ten years, the collection has grown substantially and became the depository collection for type-specimens. The collection is the most regional representative depository of ticks from the State of Paraná, and it is one of the four largest Brazilian collections in number of specimens. All material was revised, and the data were computerized and catalogued in cards. To date, the collection includes 504 vials, with 2,073 specimens, belonging to 25 species and six genera of the families Argasidae and Ixodidae. The ticks were collected in regional and state parks and in green areas from 60...

Catch crops have little effect on P and K availability of depleted soils
Provedor de dados: 21
Autores: Jensen, Lars Stoumann; Pedersen, Anders; Magid, Jakob; Nielsen, Niels Erik.
It is a well-known fact that catch crops have a significant effect on availability and loss of soil inorganic nitrogen (Thorup-Kristensen et al., 2003) and recently marked effects on soil inorganic sulphur dynamics have also been shown (Eriksen and Thorup-Kristensen 2002; Eriksen et al., 2004).    However, we know much less about the effect of catch crops on phosphorous (P) and potassium (K) mobilisation and availability for the next crop. After several years of organic cash crop production, e.g. vegetables and cereals, yield levels may gradually be limited by soil P and K availability, depending on the initial status at conversion to organic production principles. This is particularly the case during the establishment phase of certain vegetable cultures...

Catch-Quota Balancing in Multispecies Individual Fishing Quotas
Provedor de dados: 31
Autores: Sanchirico,   James N.; Holland,   Daniel S.; Quigley,   Kathryn; Fina,   Mark.
Individual fishery quotas (IFQs) are an increasingly prevalent form of fishery management around the world, with more than 170 species currently managed with IFQs. Yet, because of the difficulties in matching quota holdings with catches, many argue that IFQs are not appropriate for multispecies fisheries. Using on-the-ground-experience with multispecies IFQ fisheries in Iceland, New Zealand, Australia, and Canada, we assess the design and use of catch-quota balancing mechanisms. Our methodology includes a mix of interviews with fishery managers, industry representatives, and brokers, literature review, and data analysis. We find that a combination of incentives and limits on use rates for the mechanisms provide sufficient flexibility to the quota owner...

Catfishes of the genus Auchenipterichthys (Osteichthyes: Siluriformes: Auchenipteridae): a revisionary study
Provedor de dados: 83
Autores: Ferraris Jr.,Carl J.; Vari,Richard P.; Raredon,Sandra J.
The Neotropical auchenipterid catfish genus Auchenipterichthys is reviewed and found to include four species. Auchenipterichthys thoracatus, formerly considered to be widely distributed throughout the Amazon River basin, is found to be restricted to the upper Madeira River basin. The widespread Amazonian species that had been misidentified as A. thoracatus is, instead, A. coracoideus; a species that also occurs in the upper Essequibo River. Auchenipterichthys longimanus, the most widely distributed species of the genus, is found through much of the Amazon and Orinoco River basins. The fourth species of the genus, A. punctatus (and its junior synonym A. dantei), is found in the upper portions of the Orinoco and Negro River basins in Venezuela and the...

Autores: Fonseca,Adriel Ferreira da; Alleoni,Luís Reynaldo Ferracciú; Melfi,Adolpho José; Montes,Célia Regina.
The addition of Na-rich anthropogenic residues to tropical soils has stimulated the scientific community to study the role of sodium in both the soil solution and the exchange complex. In this study, several different methods were used to calculate the concentration of exchangeable and soluble cations and this data was then used to establish correlations between the level of these cations and both the accumulation of various elements and the dry weight of maize grown in a greenhouse under different conditions. In the closed environments of the pots, the most suitable method for calculating the effective cation exchange capacity (ECEC) was the cation exchange capacity calculated by cations removed with barium chloride solution (CEC S). Then again, the...

Cattle Accumulation and Land Use Intensification by Households in the Brazilian Amazon
Provedor de dados: 31
Autores: Caviglia-Harris,   Jill L.
In developing countries across the globe the impact of livestock on deforestation levels has been profound. This paper explores the role of the cattle industry in household decision making for small landholders in the Brazilian Amazon. Important inquiries raised in the literature are addressed, including the determinants of the co-evolution of deforestation and cattle herds, the possibility of production specialization, and the role of cattle in household livelihoods. Panel data suggest that households have changed focus from crop  introduction to cattle. Empirical models reveal that location, wealth, and education are among the important determinants of production decisions and cattle accumulation. Policy recommendations include a focus on the cattle...

Cattle Trade and the Risk of Importing Animal Diseases into the Netherlands
Provedor de dados: 31
Autores: Achterbosch,   Thom J.; Dopfer,   Dorte D.V.; Tabeau,   Andrzej A.
Projections of live cattle trade in the EU-25 assist to reduce the uncertainty on the risk of importing animal diseases in the Netherlands. The accession of 10 member states to the European Union has a potentially large impact on livestock trade in the EU as it liberalized in one stroke a trade that was administered by the Management Committee for Beef until May 1, 2004. The approach combines AG-Memod partial equilibrium with GTAP general equilibrium modelling in order to estimate the impact of quota liberalization. Quota removal will substantially alter the regional structure of livestock imports, as the share of new EU member states in the east triples to 25%. The risk outlook indicates a need for enhanced animal health services in the new member states.

Causes of Diversification in Agriculture Over Time: Evidence From Norwegian Farming Sector
Provedor de dados: 31
Autores: Culas,   Richard J.; Mahendrarajah,   Mahen.
Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread...

CAUSES OF HOUSEHOLD FOOD INSECURITY IN KOREDEGAGA PEASANT ASSOCIATION, OROMIYA ZONE, ETHIOPIA
Provedor de dados: 31
Autores: Haile,   H.K.; Alemu,   Zerihun Gudeta; Kudhlande,   G.
The main objective of the study was to examine the determinants of households' food security using a logistic regression procedure. The model was initially fitted with eleven factors, of which six were found to be significant, and all exhibited the expected signs. These include farmland size, ox ownership, fertilizer application, education level of household heads, household size, and per capita production. The result was analyzed further to compute partial effects and to conduct simulation studies on significant determinant factors. Analysis of partial effects revealed that an introduction to fertilizer use and an improvement in the educational levels of household heads lead to relatively greater probability of food security. On the other hand,...

CAUSES OF INSTABILITY IN CEREAL PRODUCTION IN ETHIOPIA
Provedor de dados: 31
Autores: Alemu,   Zerihun Gudeta.
In Ethiopia, average cereal production between the period 1990 and 2000 did not change significantly compared to the period between 1974 and 1990. However, cereal production between the period 1990 and 2000 was characterized by significant instability. This study reviews literature on factors with potential impact on instability in cereal production in Ethiopia and applies descriptive and variance decomposition procedures to determine the sources of increased instability in cereal production. It was found that production instability was caused more by increased yield instability than instability in an area. Yield instability could be the result of changes in technology, changes in policy and changes in weather conditions. It was concluded by this study...

Causes of Multifunctionality: Externalities or Political Pressure?
Provedor de dados: 31
Autores: Baylis,   Katherine R.; Casamatta,   Georges; Peplow,   Stephen; Rausser,   Gordon C.; Simon,   Leo K.
The EU has argued that some agricultural subsidies are needed to provide the optimal amount of externalities (both positive and negative) produced by agriculture.  The argument is that agriculture is "multifunctional" and externalities such as rural development and landscape would be underproduced, while some forms of pollution (such as nitrogen runoff) would be overproduced without government intervention.  Meanwhile, the United States has raised the concern that multifunctionality is primarily an argument to transfer income to producers.  In this paper, we discuss the motivation for the EU agri-environmental measures and empirically test for those underlying causes.  We find that the programs are not targeted at those regions with the highest...

Cell size and basal metabolic rate in hummingbirds
Provedor de dados: 97
Autores: Opazo,Juan C.; Soto-Gamboa,Mauricio; Fernández,Maria José.
Nucleotypic theory suggests that genome size play indirect roles in determining organismal fitness. Among endotherms this theory has been demonstrated by an inverse correlation between basal metabolic rate (BMR) and genome size. Nonetheless, accumulation of variables, especially for some key groups of endotherms, involved in C-value enigma (e.g., cell size) will fortify this theory. In this sense, hummingbird species are of particular interest because they are an energetic extreme in avian and endotherm evolution. Knowing that cell size is proportional to C-value, in this study we tested for a relationship between mean corpuscular volume of red blood cells and BMR in four species of hummingbirds ranging from 4 to 20 g. In comparison with other birds, our...

Cell surface and gene expression regulation molecules in dystrophinopathy: mdx vs. Duchenne
Provedor de dados: 48
Autores: FADIC,RICARDO.
Duchenne muscular dystrophy (DMD) is secondary to loss-of-function mutations in the dystrophin gene. The causes underlying the progression of DMD, differential muscle involvement, and the discrepancies in phenotypes among species with the same genetic defect are not understood. The mdx mouse, an animal model with dystrophin mutation, has a milder phenotype. This article reviews the available information on expression of signaling-related molecules in DMD and mdx. Extracellular matrix proteoglycans, growth factors, integrins, caveolin-3, and neuronal nitric oxide synthase expression do not show significant differences. Calcineurin is inconsistently activated in mdx, which is associated with lack of cardiomyopathy, compared to the permanent calcineurin...

Cells of yeasts adhered in corn grains and the storage perspective for use as probiotic
Provedor de dados: 52
Autores: Baptista,Antonio Sampaio; Horii,Jorge; Piedade,Sonia Maria de Stefano.
Yeasts were applied to corn grains, containing 16 or 20% moisture, at concentrations of 1 and 2%. The cellular viability was assayed at 0, 15, 30, 90 and 110 days. The cellular viability did not differ statistically among the treatments up to 30 days of storage, with the median viability of 89.10%. The average viability found at 90 days (72.20%) was lower than in the first three storage periods. After 110 days, the average viability was 61.14%. In conclusion, since yeast cells were viable up to 110 days in storage on corn grains, these can be used as a vehicle for the application of yeast as a probiotic.

We examined the detailed cellular localization of the rhoptry-associated protein-1 (RAP-1) of Babesia bovis merozoites by the post-embedding method of immuno-electron microscopy (IEM) using the anti-RAP-1 monoclonal antibody (mAb) 1C1 in order to substantiate the result in our previous report by an indirect immunofluorescent antibody test and the pre-embedding method of IEM. RAP-1 slightly distributed only in cytoplasm of merozoites, especially around the nucleus, but not in the rhoptry organelle at an early stage after invasion into a red blood cell. Then, the RAP-1 was accumulated in the rhoptry organelle and was also found in the iRBC cytoplasm, which suggests that synthesis and release of RAP-1 may occur in the iRBC. Finally, the RAP-1 was found within...

Censored catch data in fisheries stock assessment
Provedor de dados: 5
Autores: Hammond, T; Trenkel, Verena.
Landings statistics can be lower than true catches because many fish are discarded or landed illegally. Since many discards do not survive, treating landings as true catches can lead to biased stock assessments. This paper proposes treating catch as censored by bounding it below by the landings, L, and above by cL (for scalar c &gt; 1), We demonstrate the approach with a simulation study, using a Schaefer surplus production model. Parameters were estimated in a Bayesian framework with BUGS software using two sets of priors. Both the traditional true-catch method and a survey-and-effort method (which was landings free) performed worse on average than the censored approach, as measured by the Bayes risk associated with estimates of maximum sustainable yield...

Central actions of somatostatin in the generation and control of breathing
Provedor de dados: 48
Autores: Llona,Isabel; Eugenín,Jaime.
The neuropeptide somatostatin is involved in many functions in the central nervous system as well as in the periphery. When it is centrally injected, an irreversible apnea is often developed. In the present review, we discuss the effects of somatostatin as the result of its actions at three levels of the respiratory neural network: a) by modulating the output of cranial or spinal motoneurons; b) by altering the genesis of the respiratory rhythm in the brainstem; and c) by regulating the chemosensory drive input into the respiratory pattern generator

Establishment of long-term central venous access is a sine qua non step for bone marrow transplantation in children. Most frequently, long-term central venous access has been obtained via blind percutaneous cannulation of subclavian and internal jugular veins or via internal jugular vein cutdown. In order to avoid some potential minor and major complications associated with the subclavian or internal jugular approaches, the authors describe an easy, simple and safe method for central venous access through an external jugular vein cutdown that should be of interest to readers involved in the field of bone marrow transplantation. It should be also considered for children as well as adults needing central venous access via an external catheter - or totally...

Cerebral edema associated to scorpion sting: a two-case sting report
Provedor de dados: 80
Autores: Romero,N. O.; Hernández,T. J. M.
Scorpionism is a public health problem in some places in Mexico. The clinical symptoms of envenomation by scorpion sting are by sympathetic and parasympathetic stimulation, developing systemic and local symptoms. The Central Nervous System (CNS) is one of the organs that are affected. In some cases, cerebral edema develops. In this report we present two pediatric cases with the association of envenomation by scorpion sting and cerebral edema. The first case developed severe cerebral edema, which progressed to a fatal outcome; and the other case developed mild cerebral edema with a satisfactory evolution. The pathophysiology of this complication is not well known and probably is the consequence of hypoxia, secondary to respiratory failure, laryngospasm and...

Certification of Pork Products
Provedor de dados: 31
Autores: Nilsson,   Tomas K.H.; Foster,   Kenneth A.
The objective of this paper is to provide insights on the welfare distributional impact on consumer and producer welfare resulting from the development and implementation of a credence certification program in the U.S. pork sector. The certification program can provide various levels of tracking and tracing in the marketing chain. The modeling framework follows that of Nilsson (2005), which encompasses product differentiation and substitution across meat products at the consumer level and across live animal types at the farm level. Processors and retailers have potentially bilateral market power and can supply either or both certified and conventional meat products. One of the key findings is that while as the conventional market contracts and the...

Challenges for dengue control in Brazil: overview of socioeconomic and environmental factors associated with virus circulation
Provedor de dados: 26
Autores: De Tarso R.Vilarinhos, P.
Successive epidemics of dengue have been occurring in Brazil since 1986 and more than three million cases of dengue fever (DF) had already been recorded by November 2003. The introduction of the three serotypes in circulation (DEN-1, DEN- 2 and DEN-3) has always started in Rio de Janeiro. During the nineteen nineties, the incidence of dengue increased greatly as a consequence of the dissemination of Aedes aegypti in the country, beginning mainly in 1994. Between 1990 and 2000, several epidemics occurred, principally in the major urban centres of the southeast and the northeast of Brazil, where the majority of reported cases were concentrated. The first great incidence of the disease was observed in 1998, with 528,000 DF cases. Circulation of serotype 3 of...

Challenges of interdisciplinarity for forest management and landscape perception research
Provedor de dados: 26
Autores: Lewis, J.L.
Forest managers and academics seeking to forge an interdisciplinary blend of natural and social scientific research confront a formidable challenge. In addition to the daunting array of conceptual and methodological frameworks, there are fundamental questions and methodological issues regarding the respective roles of biology, social context and culture as influential factors in environmental perception. The purpose of this chapter is to present a conceptual roadmap for land managers and researchers attempting to achieve some form of disciplinary integration. I critically evaluate the theoretical postulates used in current landscape-perception research, examine the role of aesthetics and culture in landscape perception, and speculate on the potential...

Autores: Chaves,A.C.; Pinto,R.N.; Lourenço,M.T.; Mari,J.J.
The prevalent rate of psychiatry morbidity amongst patients with cancer reported in various studies ranges from 5 to 50%, a variation that can be attributed to differences in sample size, the disease itself and treatment factors. The objectives of the present study were to determine the frequency of psychiatric morbidity amongst recently diagnosed cancer outpatients and try to identify which factors might be related to further psychological distress. Two hundred and eleven (70.9%) female patients and 87 (29.1%) male patients from the chemotherapy unit of the Cancer Hospital A.C.

Changes in cell shape and desmin intermediate filament distribution are associated with down-regulation of desmin expression in C2C12 myoblasts grown in the absence of extracellular Ca2+
Provedor de dados: 56
Autores: Mermelstein,C.S.; Amaral,L.M.; Rebello,M.I.L.; Reis,J.S.N.; Borojevic,R.; Costa,M.L.
Desmin is the main intermediate filament (IF) protein of muscle cells. In skeletal muscle, desmin IFs form a scaffold that interconnects the entire contractile apparatus with the subsarcolemmal cytoskeleton and cytoplasmic organelles. The interaction between desmin and the sarcolemma is mediated by a number of membrane proteins, many of which are Ca2+-sensitive. In the present study, we analyzed the effects of the Ca2+ chelator EGTA (1.75 mM) on the expression and distribution of desmin in C2C12 myoblasts grown in culture. We used indirect immunofluorescence microscopy and reverse transcription polymerase chain reaction (RT-PCR) to analyze desmin distribution and expression in C2C12 cells grown in the presence or absence of EGTA. Control C2C12 myoblasts...

In contrast to most developed countries, most patients with primary hyperparathyroidism in Brazil are still symptomatic at diagnosis. However, we have been observing a change in this pattern, especially in the last few years. We evaluated 104 patients, 77 females and 27 males aged 11-79 years (mean: 54.4 years), diagnosed between 1985 and 2002 at a University Hospital. Diagnosis was made on the basis of clinical findings and of high total and/or ionized calcium levels, high or inappropriate levels of intact parathyroid hormone and of surgical findings in 80 patients. Patients were divided into three groups, i.e., patients diagnosed from 1985 to 1989, patients diagnosed from 1990 to 1994, and patients diagnosed from 1995 to 2002. The number of new cases...

Changes in Competitiveness of Farm Sector in Candidate Countries Prior to the EU Accession: The Case of Poland
Provedor de dados: 31
Autores: Zawalinska,   Katarzyna.
Prior to the EU accession Polish agricultural sector was experiencing serious structural problems. Not surprisingly Polish agricultural negotiations with EU were the toughest. Polish officials wanted to convince domestic rural electorate that the farms will operate on the competitive basis in enlarged EU. This paper investigates, however, how the competitiveness has been evolving yet prior to the accession, given the strong pressures within which it had to operate. We asked if Polish farms were responsive to this pressure - that is whether they were able to increase their productivity sufficiently to counter negative forces at work and maintain their competitiveness. The research showed a gloomy picture of declining farm productivity together with...

Changes in crossover distribution along a quadrivalent in a man carrier of a reciprocal translocation t(11;14)
Provedor de dados: 47
Autores: Pigozzi,M.I.; Sciurano,R.B.; Solari,A.J.
A testicular biopsy from an infertile man carrying a heterozygous chromosome translocation t(11;14) was studied with synaptonemal complex analysis and immunolocalization of the protein MLH1 for crossover detection. A full blockage of spermatogenesis at the spermatocyte stage was related to the presence of the translocation quadrivalents at pachytene. Only 2% of the quadrivalents showed full synapsis. Most of the spermatocytes showed asynaptic free ends that frequently mingled with the XY pair. The average number of crossovers per cell was diminished from a mean of 52.7 in controls to a mean of 48 in the patient. The difference between the number of crossovers in the quadrivalent and the normal bivalents was highly significant. The distribution of...

Autores: ACOSTA, Tomas J.; HAYASHI, Ken-Go; MATSUI, Motozumi; MIYAMOTO, Akio; 松井, 基純; 宮本, 明夫.
Increase in the blood supply to individual follicles appears to be associated with follicular growth rates and the ability to become the dominant follicle, while reduced thecal vascularity appears to be closely associated with follicular atresia. Therefore, this study aimed to determine the real-time changes in the vascularity of the follicle wall during the first follicular wave in cycling Holstein cows. Normally cycling and lactating cows (n=5) were examined by transrectal color Doppler ultrasonography (the sensitivity for velocity: &gt; 2 mm/sec) to determine the changes in the vasculature of the follicle wall (presence or absence of blood flow) and the diameter of follicles. A new follicular wave and ovulation were induced by GnRH injection at 48 h...

Autores: Yalcintepe,L.; Turker-Sener,L.; Sener,A.; Yetkin,G.; Tiryaki,D.; Bermek,E.
The extent of ADP-ribosylation in rectal cancer was compared to that of the corresponding normal rectal tissue. Twenty rectal tissue fragments were collected during surgery from patients diagnosed as having rectal cancer on the basis of pathology results. The levels of ADP-ribosylation in rectum cancer tissue samples (95.9 ± 22.1 nmol/ml) was significantly higher than in normal tissues (11.4 ± 4 nmol/ml). The level of NAD+ glycohydrolase and ADP-ribosyl cyclase activities in rectal cancer and normal tissue samples were measured. Cancer tissues had significantly higher NAD+ glycohydrolase and ADP-ribosyl cyclase activities than the control tissues (43.3 ± 9.1 vs 29.2 ± 5.2 and 6.2 ± 1.6 vs 1.6 ± 0.4 nmol mg-1 min-1).

Changes in nitrate reductase activity and oxidative stress response in the moss Polytrichum commune subjected to chromium, copper and zinc phytotoxicity
Provedor de dados: 61
Autores: Panda,Sanjib Kumar; Choudhury,Shuvasish.
The main aim of this paper was to investigate the effect of chromium (Cr), copper (Cu) and zinc (Zn) on nitrate reductase (NR) activity and oxidative stress responses in the moss Polytrichum commune. Cr, Cu and Zn resulted in the inhibition of NR activity. A decline in total chlorophyll content was observed after 24 and 48 h of metal treatment. Accumulation of the metals showed a dose and time dependent increase. High accumulation of Cu, Cr and Zn were seen in moss shoots after 24 and 48 h of treatment. Treatment of Cr, Cu and Zn for 24 or 48 h resulted in the increase of malondialdehyde (MDA) content in moss shoots. The highest increase was observed in shoots under Cu treatment followed by Cr and Zn. The MDA content was significantly higher after 48h....

It has been demonstrated that exposure to a variety of stressful experiences enhances fearful reactions when behavior is tested in current animal models of anxiety. Until now, no study has examined the neurochemical changes during the test and retest sessions of rats submitted to the elevated plus maze (EPM). The present study uses a new approach (HPLC) by looking at the changes in dopamine and serotonin levels in the prefrontal cortex, amygdala, dorsal hippocampus, and nucleus accumbens in animals upon single or double exposure to the EPM (one-trial tolerance).

Changes in the flora of the Netherlands in the 20th century Throughout the world, biodiversity is under major threat from human activity. As the gravity of the situation unfolds, critical analysis shows that our knowledge and understanding of these developments is still very incomplete, both globally and in individual countries. This study is concerned specifically with changes in abundance of the approximately 1,500 species of vascular plant growing wild in the Netherlands. Using species checklists, in the course of the 20th century no less than 10 million individual distribution records have been obtained for these plants at a scale level of about 1 km². These data are stored in two large databases: pre-1950 data in FLORIVON (in ‘quarter cells’), and...

Autores: Dadon, J.R.
After a massive mortality of the dominant species (the clam Mesodesma mactroides) occurred in 1995, changes in the intertidal community in sandy beaches of Argentina were monitored. Eight sampling stations were established in a 40 km open stretch and samples were taken every October each year up to 2001. Biomass, density, size frequency distribution and mean growth rates for the most abundant species were analyzed. During the mortality event, only the benthic stages of M. mactroides were affected, their total mean biomass diminishing from 1,399 g to 2 g per running meter beach. Post-mortality recruitment was normal and the growth rates for the youngest cohorts were similar to those previously reported. After a two years’ lag, the wedge clam Donax...

Changes of ongoing activity in Cebus monkey perirhinal cortex correlate with behavioral performance
Provedor de dados: 56
Autores: Lima,B.; Fiorani,M.; Gattass,R.
A Cebus apella monkey weighing 4 kg was trained in a saccadic eye movement task and while the animal performed the task we recorded the extracellular activity of perirhinal cortical neurons. Although the task was very simple and maintained at a constant level of difficulty, we observed considerable changes in the performance of the monkey within each experimental session. The behavioral states responsible for such variation may be related to arousal, motivation or attention of the animal while engaged in the task. In approximately 20% (16/82) of the units recorded, long-term direct or inverse correlations could be demonstrated between the monkey's behavioral state and the cells' ongoing activity (independent of the visual stimulation or of the specific...

Autores: Franken,   Jason R.V.; Pennings,   Joost M.E.
We propose a conceptual model that integrates transaction cost and risk behavior theories in an interdependence framework. Hypotheses are offered that relate the concepts that are central to the proposed model to the three dimensions of channel structures: the allocations of uncertainty, decision rights, and gains. An empirical research design is proposed to test the validity of the conceptual model within the context of the broiler and grain industries. The conceptual model will be validated in a structural equation modeling framework.

Landscape Character Assessment is a method that has gained prominence in England within the last 10 years. It has developed from earlier methods of landscape evaluation and Landscape Assessment. This chapter analyses the changing conceptualization of landscape between those methods, all, in some way or another, related to the government agency concerned with the countryside in England, the Countryside Commission/Agency. It illustrates how the methods, although following wider conservation debates, have strong links with the changing institutional remit of the Countryside Commission/Agency and it shows how the recent focus on landscape as being about ‘people and place’ brings socio-economic aspects into the heart of landscape assessment.

Autores: Oduor-Odote, P.M.; Struszczyk, M.H.; Peter, M.G.
Isolation of chitosan from cuticles of blue bottlefly larvae Calliphora erythrocephala, and shells of crab Sylla cerrata, lobster Panulirus ornatus, prawn Paeneaus indicus was carried out. The yield of chitin was 12.0%, 23.0%, 15.7% and 28.0% respectively. In the same order the yield of chitosan was 66.0%, 74.6% 74.3% and 75.0% from chitin. Ash in the crab and lobster chitosan demineralised with 0.5M HCl was 30.2 and 22.4% respectively. This was reduced to 0.2 % for lobster and 0.4% for crab using 2M HCl for demineralisation and 0.5M HCL was adequate for demineralisation of prawns to bring the ash content to &lt; 1%. The ash content in the blowfly larvae was negligible. The conditions used for chitosan isolation in blowfly larvae were milder requiring no...

Characteristics of Individuals Afflicted by AIDS-related Mortality in Zambia
Provedor de dados: 31
Autores: Chapoto,   Antony; Jayne,   Thomas S.
Studies conducted in Sub-Saharan Africa during the 1980s generally found a positive  correlation between socioeconomic characteristics such as education, income, and wealth and  subsequent contraction of HIV. However, as the disease has progressed, the relationship between  socioeconomic status and HIV contraction may have changed in many areas of Sub Saharan Africa,  although there is little hard evidence to support this. This paper seeks to determine the ex ante  socioeconomic characteristics of individuals who die between the ages of 15 to 59 years of age,  using nationally representative panel data on 18,821 individuals surveyed in 2001 and 2004 in  rural Zambia. The findings from this study will help policy-makers and development agencies  better...

Characteristics of spring barley varieties and crop diversity for  organic farming and variety testing
Provedor de dados: 21
Autores: Østergård, H.; Jensen, J.W.
Results from Danish spring barley variety trials including about 50-120 varieties and variety mixtures on three locations over three years under organic as well as conventional farming systems demonstrate the importance of genotype-environment interactions. This has implications for potential future organic VCU-testing; here results are shown for grain yield. Further, grain yield results from of six variety mixtures and their 14 component varieties indicate that variety mixtures may be less influenced by genotype-environment interactions compared to pure line varieties.

CHARACTERISTICS OF THE DECLINING U.S. AGRICULTURAL TRADE SURPLUS
Provedor de dados: 31
Autores: Mattson,   Jeremy W.; Koo,   Won W.
The U.S. agricultural trade surplus has fallen from $26.9 billion in 1996 to $7.3 billion in 2004, and it is shrinking even further in 2005.  The objective of this paper is to examine the characteristics of the decreasing agricultural trade surplus and determine the factors causing this decline.  U.S. imports from Canada and Mexico have more than doubled under NAFTA, and imports from non-NAFTA countries have also increased considerably.  Most increases in imports are consumer-ready and horticultural products.  U.S. exports to Canada and Mexico have also been increasing steadily, but exports to other important markets have been stagnant or declining.  Much of the declining trade surplus can be accounted for by trade with the European Union.  Results from an...

Characterization and copy number of the S27 ribosomal protein gene from amphioxus Branchiostoma belcheri tsingtauense
Provedor de dados: 74
Autores: Ma,Lifang; Zhang,Shicui; Liu,Zhenhui; Li,Hongyan; Xia,Jianjun.
A cDNA clone encoding ribosomal protein S27 (AmphiS27) was identified in the gut cDNA library of amphioxus Branchiostoma belcheri tsingtauense. This cDNA consists of 607 bp and contains a 255 bp open reading frame (ORF) corresponding to a deduced protein of 84 amino acids with a calculated molecular mass of 9,488 Da and an isoelectric point (pI) of 9.500. Alignment of the deduced AmphiS27 amino acid sequence with 12 known S27 protein sequences indicates that AmphiS27 shares 94-99% homology with its vertebrate homologue, 84-94% with invertebrate homologues and 69-72% with homologues from other eukaryotes, suggesting that AmphiS27 is more closely related to the vertebrate S27 protein than to its invertebrate counterpart. Southern blot analysis showed a...

Characterization of a laser-nitrided titanium alloy by electron backscattered diffraction and electron probe microanalysis
Provedor de dados: 5
Autores: Gordin, D; Gloriant, T; Bohn, Marcel; Guillou, A; Thibon, I; Ansel, D.
After a laser gas nitriding treatment of the Ti-7.5Al (atom %) titanium-based alloy, we used a combination of electron backscattered diffraction (EBSD) in scanning electron microscope and electron probe microanalysis (EPMA) techniques in order to efficiently characterize the different phases in the resolidified layer. Representative measurements of chemical composition and reliable determination of crystal structure were possible for each phase of the complex microstructure. The reaction zone is formed by a mixture of isostructural TiN phases with dendritic and/or 'coarse' needles morphology, fixed into a alpha'-Ti matrix (martensite) with a thin needle aspect. The nitrogen solubility was found to remain very low in the alpha'-Ti matrix (up to 2-3 atom %),...

Autores: Bruder,Juliana; Godry,Renata Cristina; Takei,Kioko; Cunha,Regina Ayr Florio da.
Mycoplasmas are a heterogeneous group of the smallest organisms capable of self replication and are known to cause many detrimental diseases in both animals and humans. These wall-less prokaryotes are enveloped by a lipoprotein membrane and their small genomes are sufficient to synthesize molecules required for growth and self-replication. Among sixteen species isolated from humans, Mycoplasma pneumoniae, an agent of primary atypical pneumonia, and the urogenital tract species Mycoplasma hominis,Ureaplasma urealyticum and Ureaplasma parvum have been confirmed to be pathogenic. Mycoplasma penetrans and Mycoplasma fermentans, which are species associated with HIV, have been investigated mainly in research laboratories. In this study we have characterized...

Characterization of new recombinant noroviruses
Provedor de dados: 5
Autores: Ambert Balay, K; Bon, F; Le Guyader, Soizick; Pothier, P; Kohli, E.
Noroviruses are important etiologic agents of acute gastroenteritis and show great genetic diversity. To characterize more fully previously detected strains that could not be assigned unequivocally to one particular genotype based on the RNA polymerase, we have sequenced a region in the capsid gene and, in some cases, in the junction between open reading frame 1 (ORF1) and ORF2. The results allowed us to identify several recombinant noroviruses: GGHb viruses were detected for the first time in France in August 2000 and then spread through France and to Europe during the following winter. Here we present the characterization of three other probable GII recombinants which showed different phylogenetic positions depending on their ORF1 and ORF2 sequences....

Carbohydrates were extracted from a sample of milk from a mink, Mustela vison (Family Mustelidae). Free neutral and acidic oligosaccharides were isolated from the carbohydrate fraction and their chemical structures were compared with those of white-nosed coati (Nasua narica, Procyonidae) and harbour seal (Phoca vitulina, Phocidae) that we had studied previously. The ratio of free lactose to milk oligosaccharides was similar to that in milk of the white-nosed coati; in both species, this ratio was much lower than that in the milk of most eutherians. The neutral oligosaccharides of mink milk had alpha(1-3)-linked Gal or alpha(1-2)-linked Fuc residues at their non-reducing ends, as in the neutral oligosaccharides of white-nosed coati milk. Some of the neutral...

Characterization of the penicillin G acylase from Bacillus megaterium ATCC 14945
Provedor de dados: 52
Autores: Souza,Vanessa Ribeiro de; Silva,Ana C. G.; Pinotti,Laura Marina; Araújo,Heloísa Sobreiro Selistre; Giordano,Raquel de Lima Camargo.
The purpose of this work was to characterize the enzyme penicillin G acylase (PGA) produced by Bacillus megaterium. Purification of the enzyme by ultra/diafiltration did not allow the detection of the PGA band by SDS-PAGE electrophoresis due to the high content of remaining proteins. However, using the DNA of the microorganism, it was possible to replicate the genes of the two B. megaterium PGA reported in literature, showing that the enzyme consisted of two sub-units, having 245 and 537 amino acids each and an average molecular mass of 26950 and 59070 Da, respectively. The parameters studied were: 1) the influence of temperature in the 25-60(0)C range, 2) pH in the 5-10 range and 3) substrate concentration, this was tested to obtain results on the...

Characterization of two new genes implicated in mineralization process of Pinctada margaritifera
Provedor de dados: 5
Autores: Cochennec-laureau, Nathalie; Fleury, Elodie; Belliard, Corinne; Levy, Peva.
A transplant is a complex surgical procedure performed to obtain a pearl after about 12 to 18 months. One of the key steps in this procedure is the transfer of the graft (piece of mantle) from the donor oyster. A functional relationship exists between the coating nature of the pearl and the cellular structure of the pearl bag portion of the graft. We have identified two genetic markers of biomineralisation in Pinctada margaritifera, the pearl oyster: Perline and Calcine, responsible for secretion of aragonite and calcite, respectively. After isolating and sequencing a portion of each of these genes, we verified the specificity of these sequences using molecular methods (RT-PCR, in situ hybridisation) and biocomputing methods (alignments, phylogenetic...

Characterizing Distributions of Class III Milk Prices: Implications for Risk Management
Provedor de dados: 31
Autores: Wang,   Dabin; Tomek,   William G.
Descriptive statistics and time-series econometric models are used to characterize the behavior of monthly fluid milk prices.  Prices in April, May and June appear to be more variable than those in subsequent months, and the spring-time prices are perhaps skewed.  Econometric models can capture the historical behavior of spot prices, but forecasts converge to the marginal distribution of the sample prices in about six months.  Futures prices for Class III milk have the expected time-to-maturity effect and converge to the respective monthly distributions of the cash prices at contract maturity (as they must, since the contracts are cash settled).  Thus, econometric models and futures quotes provide similar information about price behavior at contract...

INTRODUCTION:  The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as leisure and tourism, international ports and shipping, plus the exploitation of living or abiotic marine resources. This area is a significant resource for fisheries because many commercial fish species are abundant there, but also because of the presence of nursery and spawning areas and migratory routes linked to specific environmental characteristics. The vulnerability of these resources, which are subjected to strong anthropogenic pressures, has brought together...

Neste trabalho é apresentada uma chave dicotômica de identificação de pupas de Simuliidae com registro de ocorrência para o Sudeste do Brasil. Nós incluímos as 49 espécies que apresentam a pupa descrita. Na chave, além de caracteres comumente usados (e.g. número dos filamentos branquiais, forma do ápice e forma do casulo), foram usados caracteres não usuais (largura e comprimento relativos dos filamentos branquiais; disposição espacial das brânquias; proporção entre comprimento da brânquia e comprimento do casulo; presença e posição do assoalho do casulo). É possível diferenciar 70% das espécies de Simuliidae do Sudeste do Brasil usando apenas caracteres da pupa. Este estágio, muitas vezes, é o único do qual se obtém uma identificação precisa.

Cheap Food Policy: Fact or Rhetoric?
Provedor de dados: 31
Autores: Miller,   James C.; Coble,   Keith H.
The term “"cheap food policy"” has frequently been used as a descriptor for U.S. commodity programs by those who contend these payments to farmers ultimately result in lower food costs for consumers.  More recently, farm policy has been criticized for contributing to the obesity problem in the U.S. by making large quantities of fattening foods widely available and relatively inexpensive.  This paper econometrically evaluates the impact of direct government payments to farmers from 1960-1999 on the proportion of disposable income consumers spend on food.  The model finds the payments do not significantly affect the affordability of food.

Chemical and electric transmission in the carotid body chemoreceptor complex
Provedor de dados: 48
Autores: EYZAGUIRRE,CARLOS.
Carotid body chemoreceptors are complex secondary receptors. There are chemical and electric connections between glomus cells (GC/GC) and between glomus cells and carotid nerve endings (GC/NE). Chemical secretion of glomus cells is accompanied by GC/GC uncoupling. Chemical GC/NE transmission is facilitated by concomitant electric coupling. Chronic hypoxia reduces GC/GC coupling but increases G/NE coupling. Therefore, carotid body chemoreceptors use chemical and electric transmission mechanisms to trigger and change the sensory discharge in the carotid nerve.

Autores: Nichols, Carol; Lardiere, Sandrine; Bowman, John; Nichols, Peter; Gibson, John; Guezennec, Jean.
Exopolysaccharides (EPS) may have an important role in the Antarctic marine environment, possibly acting as ligands for trace metal nutrients such as iron or providing cryoprotection for growth at low temperature and high salinity. Ten bacterial strains, isolated from Southern Ocean particulate material or from sea ice, were characterized. Whole cell fatty acid profiles and 16S rRNA gene sequences showed that the isolates included representatives of the genera Pseudoalteromonas, Shewanella, Polaribacter, and Flavobacterium as well as one strain, which constituted a new bacterial genus in the family Flavobacteriaceae. The isolates are, therefore, members of the "Gammaproteobacteria" and Cytophaga-Flexibacter-Bacteroides, the taxonomic groups that have been...

Chemoprotective effect of cysteamine against the induction of micronuclei by methyl methanesulfonate and cyclophosphamide
Provedor de dados: 74
Autores: Santos-Mello,Renato; Deimling,Luiz Irineu; Lauer Júnior,Claudio; Carvalho,Thaís Rieger de.
Cysteamine or 2-mercaptoethylamine (MEA) is an aminothiol with a well-known radioprotective action. No specific information is available in the literature about the possible chemoprotective action of MEA against genotoxic chemical agents. This paper presents the results of studies on the ability of MEA to protect mouse bone marrow polychromatic erythrocytes against the induction of micronuclei by alkylating agents such as methyl methanesulfonate (MMS) and cyclophosphamide (CP). We observed that MEA administered intraperitoneally 30 min before or 30 min after the administration of MMS or CP significantly reduced the frequency of micronucleated polychromatic erythrocytes (MNPCEs) induced by the alkylating agents. When MEA was administered in combination with...

Chicory roots improves the taste and odour of organic pork
Provedor de dados: 21
Autores: Roepstorff, Allan; Mejer, Helena; Thomsen, Lisbeth E.; Thamsborg, Stig M.; Byrne, Derek V.; Hansen, Laurits L.; Bach Knudsen, Knud Erik; Møller, Kristian.
The carbohydrate inulin is known to reduce the production of skatole in pigs. This is caused by inulin changing the intestinal flora, so that the bacteria that produce skatole are held in check. This change in intestinal flora also reduces the number of intestinal parasites in the pigs. However the high cost of inulin makes its use in pig feed impractical.    Chicory root contains inulin and a series of other carbohydrates and secondary metabolites. Therefore we have examined whether chicory root can replace pure inulin and thereby reduce boar taint, improve the taste of pork and reduce the infection of pigs with pathogenic parasites and bacteria.

Childhood Malnutrition In China: Change Of Inequality In A Decade
Provedor de dados: 31
Autores: Chen,   Zhuo; Eastwood,   David B.; Yen,   Steven T.
A concentration index methodology to analyze the inequality in childhood malnutrition in China is outlined. Height-for-age z score is used as a measure of childhood malnutrition. Using household survey data from nine Chinese provinces, it is found that per-capita household income, household head's education, urban residence and access to a bus stop reduced malnutrition. Child's age had a nonlinear effect on the malnutrition status. Income growth and access to public transportation reduced the inequality, while rural-urban gap, provincial differentiation, and unequal distribution of household head's education increased inequality in childhood malnutrition. Gender is not a factor in either malnutrition status or inequality. Investments in infrastructure and...

Autores: Oliveira,   Victor; Chandran,   Ram.
The WIC program offers supplemental foods to low-income women, infants, and children. This study compared consumption patterns of WIC children with those of three different comparison groups: eligible nonparticipating children living in non-WIC households, eligible nonparticipating children living in WIC households, and children living in households whose income is too high to be eligible for WIC. The study provides strong evidence that participation in the WIC program increases consumption of at least some types of WIC-approved foods. Although WIC-participating children consumed significantly more calories from WIC-approved foods than children in the two comparison groups of eligible nonparticipants, there was no significant difference in total calories...

Autores: Peng,   Xuehua; Marchant,   Mary A.; Qin,   Xiang Dong; Zhuang,   Jun.
This research surveyed over 784 Chinese consumers in Shanghai and Nanjing in 2001 and 2002, evaluating their preferences for livestock product attributes using ordered-probit models and factor analyses. Empirical results confirm the heterogeneity of Chinese livestock retail markets and suggest that livestock distributors should focus on Chinese female consumers and young consumers considering cooking convenience as a key attribute. Chinese consumers with higher incomes placed less importance on product price and shopping environment and more importance on product quality and brand name. Highly-educated Chinese consumers placed more importance on the brand name attribute. Our findings also indicate that it is crucial for U.S. livestock exporters to create...

Autores: Szirmai,   Adam; Ren,   Ruoen; Bai,   Manyin.
This paper uses the detailed information in the 1995 Census of Industrial Production as a benchmark for analysing the coverage, concepts and consistency of published statistical series. On the basis of the analysis, the paper proposes a series of adjustments which result in more consistent long-run series of labour productivity for 21 manufacturing sectors from 1980-2002. For purposes of international comparisons with the USA, the paper subsequently presents industry of origin unit value ratios for the benchmark year 1995. These are used to convert Chinese value added into US dollars. In 2002, value added for the statistically well-covered sectors of Chinese manufacturing was 43 per cent of US value added, against 12 per cent in 1980. The comparative...

Cholesterol-dependent hemolytic activity of Passiflora quadrangularis leaves
Provedor de dados: 56
Autores: Yuldasheva,L.N.; Carvalho,E.B.; Catanho,M.-T.J.A.; Krasilnikov,O.V.
Plants used in traditional medicine are rich sources of hemolysins and cytolysins, which are potential bactericidal and anticancer drugs. The present study demonstrates for the first time the presence of a hemolysin in the leaves of Passiflora quadrangularis L. This hemolysin is heat stable, resistant to trypsin treatment, has the capacity to froth, and acts very rapidly. The hemolysin activity is dose-dependent, with a slope greater than 1 in a double-logarithmic plot. Polyethylene glycols of high molecular weight were able to reduce the rate of hemolysis, while liposomes containing cholesterol completely inhibited it. In contrast, liposomes containing phosphatidylcholine were ineffective. The Passiflora hemolysin markedly increased the conductance of...

Choosing and Using Indicators for Effective Social Performance Management
Provedor de dados: 31
Indicators are criteria or measures against which changes can be assessed.  Microfinance institutions (MFIs) need to use a variety of financial and social indicators, to track both their financial and social performance and the impacts they are having on their intended beneficiaries.  There is a set of standardized financial indicators that allow financial performance measurement, but indicators of social performance are usually more complicated.  This is because an almost infinite number of changes can be brought about by a programme, and each possible change can be measured by a number of different indicators.  However, as this Practice Note shows, it is possible for MFIs to develop and apply a set of useful indicators, if they follow some simple steps...

This study presents a framework to analyze how uncertainty about product attributes affects consumers' WTP for brand name products over generic ones, incorporating key elements of a random utility model and product attribute models. We found that in comparison to electronics, clothing, and processed food, consumers buy brand name vegetables and fruits mainly because of quality uncertainty, and they can easily reduce uncertainty of product quality of fresh vegetables and fruits by seeing, touching, smelling, and tasting. Hence, consumers are less willing to pay for brands of fresh vegetables and fruits. However, simulation results show that brands of fresh fruits and vegetables may have a similar price premium as other products, but they lack the market...

Chromium stress in plants
Provedor de dados: 61
Autores: Panda,S.K.; Choudhury,S.
The article presents an overview of the mechanism of chromium stress in plants. Chromium is known to be a toxic metal that can cause severe damage to plants and animals. Chromium-induced oxidative stress involves induction of lipid peroxidation in plants that causes severe damage to cell membranes. Oxidative stress induced by chromium initiates the degradation of photosynthetic pigments causing decline in growth. High chromium concentration can disturb the chloroplast ultrastructure thereby disturbing the photosynthetic process. Like copper and iron, chromium is also a redox metal and its redox behaviour exceeds that of other metals like Co, Fe, Zn, Ni, etc. The redox behaviour can thus be attributed to the direct involvement of chromium in inducing...

The association of cytogenetic and molecular techniques has contributed to the analysis of chromosome organization and phylogeny in plants. The fluorochrome GC-specific CMA3, fluorescent in situ hybridization (FISH) and RAPD (Random Amplified Polymorphic DNA) markers were used to investigate chromosome structure and genetic relationships in Hypochaeris (Asteraceae). Seven species native to South America, and two species introduced from Europe (H. glabra and Hypochaeris sp) were studied. FISH with rDNA probes identified one or two loci of 18S-5.8S-25S rDNA in the South American Hypochaeris species and one locus in the European species. Only one 5S rDNA locus was seen in all species studied. Blocks of GC-rich heterochromatin (CMA-positive bands) associated...

chronic myeloid leukemia (CML) have been described. This chromosomal region contains the tumor suppressor gene TP53 that may be an important factor in the evolution of this disease. In this study, we used flow cytometry and western blotting to assess p53 protein expression and single stranded conformational polymorphism to examine TP53 gene alterations in three patients with CML who showed alterations in 17p. Only the case with del(17)(p11) had p53 expression positive by flow cytometry and an abnormal migration pattern by SSCP analysis. The importance of the correlation between the results obtained with these techniques, as well as the clinical course of the patients, are discussed.

Chromosome evolution in tiger beetles: Karyotypes and localization of 18S rDNA loci in Neotropical Megacephalini (Coleoptera, Cicindelidae)
Provedor de dados: 74
Autores: Proença,Sónia J.R.; Collares-Pereira,Maria João; Serrano,Artur R.M.
Four Neotropical tiger beetle species, three from the genus Megacephala and one from the genus Oxycheila, currently assigned to the tribe Megacephalini were examined cytogenetically. All three Megacephala species showed simple sex chromosome systems of the X0/XX type but different numbers of autosomal pairs (15 in M. cruciata, 14 in M. sobrina and 12 in M. rutilans), while Oxycheila tristis was inferred to have a multiple sex chromosome system with four X chromosomes (2n = 24 + X1X2X3X4Y/X1X1X2X2X3X3X4X4). Fluorescence in situ hybridization (FISH) using a PCR-amplified 18S rDNA fragment as a probe revealed the presence of rDNA clusters located exclusively on the autosomes in all the Megacephala species (five clusters in M. cruciata, eight in M. sobrina and...

Chromosome loss in bi-parental progenies of tetraploid Pacific oyster Crassostrea gigas
Provedor de dados: 5
Autores: Mccombie, Helen; Lapegue, Sylvie; Cornette, Florence; Ledu, Christophe; Boudry, Pierre.
Alterations of chromosome number have been observed in the somatic tissue of Crassostrea gigas diploids and artificial polyploids. Tetraploid oysters with abnormal chromosome numbers in some or all of their tissue are considered undesirable as parents either for triploids (produced via a cross with diploids and of aquacultural interest) or for tetraploid breeding. Aneuploid tetraploid oysters may confer the tendency to lose chromosomes and to revert to lower ploidy levels to their offspring. More directly, their offspring could have a lower ploidy because of potential links between somatic and gametic chromosome loss. The present study evaluated the phenomenon in six bi-parental tetraploid families bred from parents of differing somatic ploidy quality. The...

Chromosome numbers and meiotic behavior of some Paspalum accessions
Provedor de dados: 74
Autores: Adamowski,Eleniza de Victor; Pagliarini,Maria Suely; Bonato,Andréa Beatriz Mendes; Batista,Luiz Alberto Rocha; Valls,José Francisco Montenegro.
Chromosome number and meiotic behavior were evaluated in 36 Brazilian accessions of the grass Paspalum (which had never previously been analyzed) to determinate which accessions might be useful in interspecific hybridizations. The analysis showed that one accession of Paspalum coryphaeum was diploid (2n = 2x = 20) and one accession of Paspalum conspersum hexaploid (2n = 6x = 60), the remaining 34 accessions being tetraploid (2n = 4x = 40). The pairing configuration was typical for the ploidy level i.e. in the diploid, chromosomes paired as 10 bivalents, in tetraploids as bi-, tri- and quadrivalents, and in hexaploid as 30 bivalents. A low frequency of meiotic abnormalities (less than 10%) was observed in the diploid, hexaploid and some tetraploid...

We determined if the dorsal raphe nucleus (DRN) exerts tonic control of basal and stimulated sodium and water intake. Male Wistar rats weighing 300-350 g were microinjected with phosphate buffer (PB-DRN, N = 11) or 1 µg/0.2 µl, in a single dose, ibotenic acid (IBO-DRN, N = 9 to 10) through a guide cannula into the DRN and were observed for 21 days in order to measure basal sodium appetite and water intake and in the following situations: furosemide-induced sodium depletion (20 mg/kg, sc, 24 h before the experiment) and a low dose of dietary captopril (1 mg/g chow). From the 6th day after ibotenic acid injection IBO-DRN rats showed an increase in sodium appetite (12.0 ± 2.3 to 22.3 ± 4.6 ml 0.3 M NaCl intake) whereas PB-DRN did not exceed 2 ml (P &lt;...

Autores: Soares,E.C.; Larsson,M.H.M.A.; Yamato,R.J.
Echocardiographic aspects of chronic mitral valvular disease were studied and compared to physical, radiographic and electrocardiographic aspects. Seventy dogs were used, and clinical examination, thoracic radiography, electrocardiogram and echocardiogram were performed. Correlations between regurgitation severity with cardiac failure functional class and murmur intensity were observed. The electrocardiogram showed a low sensibility in detecting cardiac chamber enlargement, caused by mitral regurgitation. All the dogs with severe mitral regurgitation showed cardiomegaly according to thoracic radiographies.

Provedor de dados: 71
Autores: Aldana,Elis; Zamora,Ezequiel; Lizano,Eliécer.
El propósito del presente trabajo es el estudio del ciclo biológico de R. robustus alimentado con sangre humana. Los triatominos procedían de una colonia fundada con ejemplares capturados en Caño Tigre, estado Mérida, Venezuela. Los insectos fueron alimentados a través de membrana de látex en un alimentador artificial a 37ºC con sangre humana con citrato de sodio como anticoagulante. Se observó una fecundidad de 13,9 huevos/hembra/semana, fertilidad 78,32 %, el ciclo biológico desde huevo a adulto se completó en aproximadamente 70 días. Los resultados muestran que R. robustus es capaz de reproducirse exitosamente al ser alimentada con sangre humana, lo cual contribuye a su potencialidad como especie domiciliaria y transmisora de la Enfermedad de Chagas.

Sukkerstoffet inulin er kendt for at kunne nedsætte dannelsen af skatol hos svin. Det skyldes at inulin ændrer tarmfloraen, så bakterier der danner skatol bliver holdt i skak. Samtidig bevirker den ændrede tarmflora at grisene får færre indvoldsorm. Inulin er imidlertid for dyrt til, at det kan betale sig at bruge det i svinefoder.    Cikorierødder indeholder inulin og en række andre kulhydrater plus sekundære metabolitter. Derfor har vi undersøgt om cikorierødder kan erstatte ren inulin og derigennem mindske ornelugten, forbedre smagen og nedsætte grisenes smitte med sygdomsfremkaldende parasitter og bakterier.

Autores: Inda Junior,Alberto Vasconcellos; Kämpf,Nestor; Giasson,Élvio; Silva,Jacques Aveline Loureiro da.
A cinética da dissolução redutiva da goethita e da hematita em solos poligenéticos foi avaliada por dois modelos matemáticos. O modelo Kabai descreveu a dissolução em um único segmento linear, não discriminando fases de um mesmo óxido ou de diferentes óxidos em cada amostra. A análise comparativa da estabilidade de cristais por este modelo somente pode ser realizada entre amostras distintas. O modelo Avrami-Erofejev descreveu a dissolução em mais de um segmento linear na maioria das amostras. Este modelo discriminou fases de um mesmo óxido e ofereceu condições para classificar o grau de estabilidade destes minerais dentro de cada amostra. Os modelos indicaram menor estabilidade da hematita em relação à goethita frente à dissolução redutiva, principalmente...

Modelos mecanísticos baseados em princípios de transporte de solutos pode ser de grande utilidade para prever os impactos do cultivo de florestas plantadas, por exemplo, com eucalipto sobre o capital e fluxo de nutrientes no solo. Dentre as variáveis de entrada demandadas por tais modelos, tem-se os valores das constantes Vmax, Km e Cmin da cinética de absorção iônica. Assim, os objetivos do presente trabalho foram determinar os valores de Vmax, Km e Cmin para K, Ca e Mg, bem como avaliar as respectivas eficiências nutricionais de clones de eucalipto. O estudo consistiu de três ensaios em solução nutritiva (um para cada cátion), sendo utilizadas mudas propagadas vegetativamente de um híbrido de E. grandis x E. urophylla (clone 1213) e de três híbridos de...

Cinética de inativação de inibidores de tripsina e de insolubilização de proteínas de diferentes cultivares de soja
Provedor de dados: 96
Autores: Miura,Edna Mayumi Yuahasi; Silva,Rui Sérgio dos Santos Ferreira da; Mizubuti,Ivone Yurika; Ida,Elza Iouko.
A soja (Glycine max (L.) Merrill) é uma das leguminosas mais estudadas, em virtude de sua intensa utilização como fonte de óleo comestível e proteína para alimentação humana e animal. A presença de inibidores de tripsina na soja limita sua utilização, tornando necessário o processamento térmico para melhorar sua qualidade nutricional. Entretanto, o processamento térmico excessivo ou inadequado pode reduzir a qualidade da proteína. Neste trabalho, foram utilizados cultivares de soja BR-36, com atividade normal de inibidores de tripsina, e cultivares BRM 95-5297 e BRM 95-5262, com baixas atividades de inibidores de tripsina. As farinhas com 10 e 16% de umidade foram aquecidas em banho a 95°C, com cinco intervalos (15, 25, 50, 75 e 100 minutos) de retenção;...

Cell population growth is gated to occur in particular circadian phases, which has been known for over four decades in various organisms including cyanobacteria and human. However, little is known as to which cell cycle phases from G(1) to M are primarily regulated by the circadian rhythm or when in a circadian cycle this primary regulation takes place. We report here that in the flagellate alga Euglena gracilis grown photoautotrophically, the circadian rhythm primarily prevented developmentally matured G(2) cells from progressing to mitosis, such that cell population growth occurred only during subjective night. In addition, we found that the circadian rhythm also arrests G(1)-to-S and S-to-G(2) transitions at particular circadian phases.

Circadian rhythms of resistance to UV-C and UV-B radiation in Euglena as related to 'escape from light' and 'resistance to light'
Provedor de dados: 19
Autores: Bolige, Aoen; Kiyota, Maki; Goto, Ken; 後藤, 健.
Radiation-induced stress, either from visible or UV light, is strongest at midday. We found that, in the absence of stress or time cues, Euglena gracilis Z was the most resistant to UV-C and UV-B at subjective midday, whether judged from immediate or reproductive survival. The circadian UV-resistance rhythms were free-running in stationary cultures under 1-h light/1-h dark cycles or continuous darkness, indicating that cell-cycle dependent DNA susceptibility to UV was not involved. We moreover examined what was the primary cause of the circadian U-V resistance, estimated as the immediate cell survival. The half-maximal lethal dose (LD50) of UV-C at subjective midday (the most resistant phase) was 156 J/m(2), which is similar to 3-fold that at subjective...

Citizens' Attitudes Towards Multifunctional Agriculture
Provedor de dados: 31
Autores: Hyytia,   Nina; Kola,   Jukka.
This paper examines Finnish citizens' attitudes towards multifunctional agriculture and further, the connections among these attitudes, consumers' willingness to pay, and some socio economic factors. Attitudinal dimensions were executed by using factor analysis. The respondents (N=1300) were distributed into clusters based on their attitudes. It would be expected that people who have positive attitudes, would also state high values of WTP. Instead, this study suggests that attitudes and WTP do not have a positive relation. People are willing to support domestic agriculture as a provider of safe and high-quality food. However, a remarkable proportion of Finnish citizens have a positive attitude towards externalities and joint products of agriculture.

Provedor de dados: 21
Autores: Nielsen, Tina Skau; Straarup, Ellen Marie; Sejrsen, Kristen.
Mælkens indhold af CLA er interessant ud fra en human ernæringssynsvinklen, idet flere undersøgelser har vist en positiv sammenhæng mellem indtag af CLA og risikoen for cancer. Der blev fundet en betydelig variation mellem bedrifter i mælkens indhold af CLA, og ikke noget entydigt billede af niveauet i konventionel og økologisk mælk. Resultater viser desuden at foderrationens sammensætning påvirker niveauet, men også at der synes at være en forskel mellem de enkelte køer.

Classical Horizontal Inequities in the Provision of Agricultural Income Support
Provedor de dados: 31
Autores: Allanson,   Paul.
This paper explores the redistributive effect of classical horizontal inequities induced by agricultural support policy. Within farm type horizontal inequity (HI) is associated with differences in the level of support received by farms of a given type and level of pre-support income, whereas between farm type HI arises from systematic differences in support levels between commodity regimes. The overall redistributive effect of HI in Scottish agriculture is shown to be substantial, though systematic discrimination between farm types proves not to be the major cause. The imperfect targeting of support revealed by the empirical findings has implications for the design of policy.

RESUMO: O objetivo deste trabalho foi utilizar o método de classificação não-supervisionada (fuzzy K-means) em dados de produtividade para delineamento de zonas de manejo. O estudo foi conduzido a partir de dados georregerenciados de produtividade de grãos coletados por sensores e DGPS. Foram mapeadas três safras (milho-soja-arroz) em área de plantio direto irrigada por pivô central. Os dados de produtividade foram interpolados pelo inverso da distância resultando em um mapa de resolução espacial de 5 x 5 m. Os valores relativizados em relação à média de produtividade foram comparados ao longo do tempo nos mesmos locais. Como referência, foram escolhidas três classes de produtividade para delinear as zonas de manejo segundo os seguintes critérios:...

Classification of Agri-Tourism / Rural Tourism SMEs in Poland (on the Example of the Wielkopolska Region)
Provedor de dados: 31
Autores: Przezborska,   Lucyna.
The paper is based on data from a questionnaire survey (interviews) conducted in the western part of Poland on 183 rural tourism and agri-tourism small and medium enterprises. The classification of enterprises was based on the methodology proposed by Wysocki (1996) and included the k-means clustering algorithm. As the result of the research three types of SMEs were separated, including the top resilient enterprises aimed mainly at tourism activity and usually connected with horse recreation, a cluster of mixed SMEs for which tourism activity was an additional and less important source of income, and a group of SMEs for which tourism activity was an additional but important source of income. The classification may be used as a hint for rural development...

Poucos trabalhos, no entanto, consideram o perfil correspondente a essas precipitações.

Climate change and agroecosystems: the effect of elevated atmospheric CO2 and temperature on crop growth, development, and yield
Provedor de dados: 65
Autores: Streck,Nereu Augusto.
The amount of carbon dioxide (CO2) of the Earth´s atmosphere is increasing, which has the potential of increasing greenhouse effect and air temperature in the future. Plants respond to environment CO2 and temperature. Therefore, climate change may affect agriculture. The purpose of this paper was to review the literature about the impact of a possible increase in atmospheric CO2 concentration and temperature on crop growth, development, and yield. Increasing CO2 concentration increases crop yield once the substrate for photosynthesis and the gradient of CO2 concentration between atmosphere and leaf increase. C3 plants will benefit more than C4 plants at elevated CO2. However, if global warming will take place, an increase in temperature may offset the...

More rapid than normal global climate change as represented by rising temperatures and more erratic and severe weather events have heightened the interest in how farmers use weather information. The greenhouse influence through driving climate change will likely be affecting agricultural efforts for some years to come.  It behooves us to pay attention to this phenomenon, and especially put effort into understanding how farmers will respond to information about climate generally and forecasts in particular. This research is being funded by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration.

Climate Policy Design under Uncertainty
Provedor de dados: 31
Autores: Pizer,   William A.
The uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decision-makers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time path of mitigation efforts as well as whether those efforts, by design, focus on effort or outcome. This paper considers two choices-price versus quantity controls and absolute versus relative/intensity emissions limits-demonstrating that price controls and intensity emissions limits favor certainty about cost over climate benefits and future emissions reductions. The paper then argues that in the near term, this favoritism is desired.

Climate Variability Reveals Complex Events for Tularemia Dynamics in Man and Mammals
Provedor de dados: 7
Autores: Palo, Thomas R; Mid-Sweden University; Thomas.palo@miun.se.
Tularemia is caused by the bacterium Francisella tularensis, but the natural reservoir is unknown and environmental conditions for outbreaks in mammals and man are poorly understood. The present study analyzed the synchrony between the North Atlantic Oscillation (NAO) index, the number of human cases of tularemia reported in Sweden, and the density of hares. Climate variation at a lag of 2 yr explained as a single factor ~ 27% of the variation in the number of tularemia cases over time. A low NAO index, indicating cold winters, and low water flow in rivers during the coming summer were associated with high numbers of human cases of tularemia 2 yr later. The number of mountain hares was not related to NAO or to the number of cases of tularemia. The change...

Infrastructure systems and services (ISS) are vulnerable to changes in climate.  This paper reports on a study of the impact of gradual climate changes on ISS in Hamilton City, New Zealand.  This study is unique in that it is the first of its kind to be applied to New Zealand ISS.  This study also considers a broader range of ISS than most other climate change studies recently conducted.   Using historical climate data and four climate change scenarios, we modelled the impact of climate change on water supply and quality, transport, energy demand, public health and air quality.  Our analysis reveals that many of Hamilton City's infrastructure sectors demonstrated greater responsiveness to population changes than changes in gradual climate change. Any...

The tropical north region of Minas Gerais State is one of the least developed of Brazil and viticulture could be an alternative to develop its agriculture zone. The objective of this work was to evaluate the climatic potential of that region for wine grape production. The evaluations were carried out applying the Multicriteria Climatic Classification System (Geoviticulture MCC System), that utilizes three reference climatic indexes (Dryness Index - DI, Heliothermal Index - HI and Cool Night Index - CI). Three locations - Pirapora (17º 21'S, 44º56'W, 489m), Montes Claros (16º43'S, 43º52'W, 647m) and Diamantina (18º15'S, 43º36'W, 1297m) - and two potential production cycles along the year - October to March (spring-summer period) and April to September...

Abiotic stresses observed in the village Kaudikol , district Cuttack, Orissa have been recorded for 8 years and analysed. Survey data collected for four years (1996-97 to 1999-2000) from the farmers of this village have been analysed to find out their livelihood system, importance of rice in this system and the coping mechanisms followed by them in case of loss to the kharif rice crop. The abiotic stresses have been found to cause flood / submergence to different degrees in 5 years, drought in 3 years and cyclone in one year out of the total 8 years, causing production losses to rice. The maximum losses to rice crop have been observed during 1999 kharif season due to cyclone. It has been found that rice is the major crop during the kharif season, covering...

Little is known about the epidemiology of severe rotavirus-associated gastroenteritis in Brazil. Given the morbidity associated with this condition and the importance of having detailed knowledge about the impact of rotavirus infection on the epidemiology of acute diarrhea in children, especially those with the most severe diarrheal conditions, we retrospectively reviewed the medical records of all pediatric patients admitted to a tertiary hospital in Salvador, Brazil, due to rotavirus-associated gastroenteritis during one year. It was observed that rotavirus was responsible for 15.6% of the hospitalizations caused by diarrhea and/or vomiting during the period of the study and that 87 of 218 (39.1%) patients seen at the emergency room with...

Clinical and molecular aspects of severe malaria
Provedor de dados: 42
Autores: Kirchgatter,Karin; Del Portillo,Hernando A.
The erythrocytic cycle of Plasmodium falciparum presents a particularity in relation to other Plasmodium species that infect man. Mature trophozoites and schizonts are sequestered from the peripheral circulation due to adhesion of infected erythrocytes to host endothelial cells. Modifications in the surface of infected erythrocytes, termed knobs, seem to facilitate adhesion to endothelium and other erythrocytes. Adhesion provides better maturation in the microaerophilic venous atmosphere and allows the parasite to escape clearance by the spleen which recognizes the erythrocytes loss of deformability. Adhesion to the endothelium, or cytoadherence, has an important role in the pathogenicity of the disease, causing occlusion of small vessels and contributing...

Autores: Ferraro,G. C.; Moraes,J. R. E.; Pereira,G. T.; Moraes,F. R.; Bueno de Camargo,M. H.
The aim of this study was to evaluate the effect of snake venom derived fibrin glue on the healing of the deep digital flexor tendon, during three periods. The tendon of the 2nd digit of 30 thoracic limbs of dogs was partially sectioned for glue application. Biopsies were performed 7, 15, and 30 days post surgery for the clinical and morphological study of tendons. Analysis of the results showed that 73.3% of the tendons showed stump retraction and 16.6% moderate to excessive adherence, which affected sliding. There was a significant difference in the number of inflammatory cells among the three studied periods, being the highest on day 15. The morphological analysis revealed a typical tendon healing process with a lower level of inflammation in the acute...

Clinical application of pet
Provedor de dados: 52
Autores: Lomeña,Francisco; Soler,Marina.
Positron emission tomography (PET) is an imaging modality that gives information on tissue metabolism and functionalism, different from other imaging techniques like computed tomography (CT) and magnetic resonance imaging (MRI), which provide anatomical or structural information. PET has reached its development in biomedical research because of its capacity to use analogous compounds of many endogenous substance as tracers, and to measure, in vivo and in a non-invasive way, their consumption by the different organs and tissues of the mammalian body. Fluordeoxyglucose-F18 (FDG) PET has been proven to be a tracer adequate for clinical use in oncology and in many neurological diseases, with an excellent cost-efficiency ratio. The current PET-CT scanners can...

Autores: Akeredolu,I. A.; Addo,A. A.; Akeredolu,O. A.
The purpose of this study was to formulate a weaning diet from pearl millet-conophor nut flour that would promote growth. For PER, BV, NPU and TD values, casein diet was the most superior while millet-conophor diet and soy-ogi diet compared favourably with each other. For the clinical measurements of the experimental rats on the soy -ogi diet and millet-conophor diet, apart from the urinary urea level of the group on millet conophor diet which was much higher than soy-ogi, there was no difference in any of the other parameters measured. It was therefore, concluded that the millet-conophor, diet was favourably well with the soy-ogi.

The density of Clinostomum complanatum metacercariae by the body regions and among the size classes of Rhamdia quelen was compared. The host size classes were defined by cluster analysis, using weight and total length as attributes. These values were related with environmental characteristics and host biological data. In all the host size classes H and PeF, CF and PF, and P and AF regions pairs, showed similar density (tested by X² test). The hosts with 30-36 cm showed largest parasite density in all the regions, except in CAV. Fishes smaller than 11 cm did not show significant differences of parasite density in all body regions. In the other classes, H was the most infected region, followed by PeF. The results suggested that the environmental conditions...

Cloning and sequence analysis of tomato cpDNA fragments: towards developing homologous chloroplast transformation vectors
Provedor de dados: 61
Autores: Berger,Irving Joseph; Carraro,Dirce Maria; Bock,Ralph; Azevedo,Ricardo Antunes; Carrer,Helaine.
With the view of developing chloroplast transformation vectors based on homologous targeting regions for tomato (Lycopersicon esculentum L.), plastid DNA fragments of tomato cv. IAC-Santa Clara were cloned and analyzed. Isolation and cloning of PstI/SalI chloroplast fragments into the pBlueScript vectors yielded the plasmids pIJB1 and pIJB2 with cpDNA fragments of 8.6 kb and 6.4 kb, respectively. DNA sequencing and computer analyses revealed that the tomato sequences cloned display from 93 to 100 % of identity to the respective fragments in tobacco, which is more pronounced in coding regions. The intergenic spacers are somewhat less conserved suggesting that evolutionary divergences occurred mainly in these putative non-coding regions. The most remarkable...

Chitinase plays a positive role in the pathogenicity of Bacillus thuringiensis to insect pests. We used touchdown PCR to clone the chitinase (Schi) gene from Bacillus thuringiensis serovar sotto (Bt sotto) chromosomal DNA. Our DNA sequencing analysis revealed that the Bt sotto Schi gene consists of an open reading frame (ORF) of 2067 nucleotides with codes for the chitinase precursor. We also found that the putative promoter consensus sequences (the -35 and -10 regions) of the Bt soto Schi gene are identical to those of the chiA71 gene from Bt Pakistani, the chiA74 gene from Bt kenyae and the ichi gene from Bt israelensis. The Schi chitinase precursor is 688 amino acids long with an estimated molecular mass of 75.75 kDa and a theoretical isoelectric point...

Closing nutrient cycles in Dutch organic farming: an explorative scenario study of agronomic consequences
Provedor de dados: 21
Autores: van de Ven, Gerrie; Bos, Jules.
Given the principles of organic agriculture, nutrient cycling in Dutch organic farming can be characterised as imperfect, mainly because of large imports of nutrients from conventional agriculture and from abroad. Recently, research has been initiated into the perspectives for better closing nutrient cycles by intensifying the exchange of (by-)products between organic farming sectors. The linear programming model was developed to quantify under different scenarios the agronomic consequences of further closing nutrient cycles in terms of changes in land use and exchange of (by-)products.   Better closing of nutrient cycles requires an increase in the proportion of Dutch feed ingredients in animal diets, an increase in the proportion of feed and leguminous...

Autores: Baldassi,L.
Clostridium is an anaerobic bacterial genus. The clostridia produce more protein toxins than any other bacterial genus and are a rich reservoir of toxins for research and medicinal uses. Clostridia are widely spread in the environment: soil, dust and water, presenting more than 120 described species, although few can cause diseases. Diseases can grossly be divided into neurotropic disorders (nervous system is primarily affected), enterotoxemias (affecting intestinal tract and parenchymatous organs), and gas gangrene (myonecrosis with toxemia). Undoubtedly the most widely recognized infection due to anaerobes was clostridial myonecrosis, but recently interest has arisen for the role of clostridia in intestinal diseases.

CN-SIM - a model for the turnover of soil organic matter. I: Long term carbon development
Provedor de dados: 21
Autores: Petersen, B.M.; Berntsen, J.; Hansen, S.; Jensen, L.S.
A computer model is presented that describes the flow of C and N in the soil. It employs a structure with conceptual compartments. Organic matter is represented by seven different compartments, two for added matter, two for soil microbial biomass, one for microbial residues, one for native organic matter, and one for inert organic matter. The latter pool probably represents both truly inert matter, and matter with a very slow turnover. This paper describes the parameterisation and performance of this model on selected long-term field data from United Kingdom, Sweden and Denmark. Statistical methods were employed to optimise parameters, and obtain proximate confidence intervals for these parameters. Very satisfactory simulations could be acquired, using the...

A computer model is presented, which describes the transformations of C and N in the soil. The development has been divided into two interdependent tasks, the first being development of long-term SOC simulation capabilities, and the second being short-term simulations of C and N, as described in this paper. A number of existing, independent laboratory experiments, covering a range of amendments, have been used for this task. The amendments includes a variety of different crop residues and animal manure. These experiments have included measurements of 13C, 14C and 15N in various pools, and the model facilitates the simulation of these isotopes. Non-linear, automated optimisation procedures were utilised wherever feasible. The model generally yielded good...

CO2 Allowance Allocation in the Regional Greenhouse Gas Initiative and the Effect on Electricity Investors
Provedor de dados: 31
Autores: Burtraw,   Dallas; Kahn,   Danny; Palmer,   Karen L.
The Regional Greenhouse Gas Initiative (RGGI) is an effort by nine Northeast and Mid-Atlantic states to develop a regional, mandatory, market-based cap-and-trade program to reduce greenhouse gas (GHG) emissions from the electricity sector. The initiative is expected to lead to an increase in the price of electricity in the RGGI region and beyond. The implications of these changes for the value of electricity-generating assets and the market value of the firms that own them depends on the initial allocation of carbon dioxide allowances, the composition of generating assets owned by the firm, and the locations of those assets. Changes in asset values inside the RGGI region may be positive or negative, whereas changes outside of the RGGI region are almost...

Coaliciones fantasmas, esencialismos políticos y corrupción (Temas)
Provedor de dados: 122
Autores: Burbano de Lara, Felipe.
Este artículo reflexiona sobre la inclinación de los partidos políticos ecuatorianos a ocultar sus pactos y acuerdos. Sostiene que el funcionamiento de “coaliciones fantasmas” -como las ha definido el politólogo Andrés Mejía- hay que explicarlas en la necesidad de los partidos y de sus líderes de sostener -en el espacio público- identidades ligadas a principios de legitimación política y valores éticos irreductibles. La negociación política y los pactos con el gobierno, inevitables en democracia, son entendidos como daños irreversibles a la identidad política, un mestizaje inaceptable desde el punto de vista de la imagen pública. De allí que los acuerdos deban ser ocultados, negados, aún cuando la práctica cotidiana les empuje a buscarlos constantemente.

Autores: Kriesel,   Warren; Landry,   Craig E.; Keeler,   Andrew G.
Coastal communities cannot depend on funding from the state or federal government to maintain high-quality beaches that benefit the public and attract tourist revenues.  This article investigates the feasibility and efficiency of beach improvement projects at two Georgia barrier islands through the alternative funding mechanisms of general-revenue financing and user fees.  Benefits are calculated from observable sources.  The analyses presented support beach improvement as an effective policy on both islands under all scenarios considered.

Coastal Impacts of Water Abstraction and Impoundment in Africa: the Case of Rufiji River
Provedor de dados: 20
Autores: Shaghude, Y.W.
Construction of large dams with reservoir type storage impound water behind them for seasonal annual, and in some cases for multi-annual storage and regulation of a river. Similarly, tubewells abstract surface and ground water bodies from their natural flow. The impoundment of water by damming and its abstraction through tubewells are common practices in the world and even within the Africa region (WCD, 2000). Globally, the number of large dams has grown at a tremendous pace during the last 50 years (Fig. 1.1) The fast growth in dam construction is driven by an increasing demand of water from urban and rural communities for reliable freshwater supply, agricultural irrigation and hydro-electric power. As these practices become more widespread, they are...

Cobertura del riesgo precios en los mercados de futuros para carne bovina en el marco de la experiencia uruguaya de 1993.
Provedor de dados: 31
Autores: Lanfranco,   Bruno A.
En la pasada década, Uruguay tuvo su primera experiencia con el mercado de futuros de novillos para faena (MFN), el que funcionó durante los últimos meses de 1993 y hasta comienzos de 1994.  El hecho que el MFN no sobreviviera más que unos pocos meses no implica necesariamente que los mercados de futuros para ganado en pie sean inviables en nuestro país.  En este trabajo se examinaron algunas de las posibles razones que pueden explicar su fracaso.  Es posible que al momento de su implementación no estuvieran dadas todas las condiciones necesarias para su desarrollo.

Cobertura morta do solo no cultivo de alface cv. Regina 2000, em Ji-Paraná/RO
Provedor de dados: 64
Autores: Carvalho,Jimmy Elizio de; Zanella,Fabio; Mota,José Hortêncio; Lima,Ana Lúcia da Silva.
Conduziu-se este estudo com o objetivo de avaliar o efeito de diferentes materiais de cobertura do solo na produtividade da alface (Lactuca sativa L. cv. Regina 2000). O delineamento experimental utilizado foi o de blocos casualizados, utilizando-se cinco tratamentos (palha de arroz, palha de café, Brachiaria brizantha L., serragem, testemunha sem cobertura morta) e quatro repetições. A produtividade foi avaliada pelo número de folhas por planta, acúmulo de massa fresca e massa seca. Verificou-se que todos os materiais empregados como cobertura, controlaram a infestação de plantas invasoras. Entretanto, verificou-se uma grande infestação na testemunha promovendo redução de produtividade.

Autores: Boelt, B.; Deleuran, L.C.
To maintain the integrity of organic farming systems guidelines to ensure coexistence between genetically modified (GM), conventional and organic crops should be implied. Since seed is moved cross borders a regulatory system is need to allow for organically produced seed of varieties adapted to organic production systems being available to organic farmers both in developed and developing countries.

Co-existence with GMOs and organic seed production
Provedor de dados: 21
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards.  Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds.   Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed. With the increasing area of GM-crop production as well as in the number of crops in which GM-varieties are available the need for guidelines to ensure coexistence are becoming increasingly essential....

Co-financing Implications for Regional Policy-Making: A Case Study for the Agri-environmental Programme in Saxony-Anhalt
Provedor de dados: 31
Autores: Kirschke,   Dieter; Hager,   Astrid; Jechlitschka,   Kurt; Wegener,   Stefan.
Financing agri-environmental programmes in the European Union (EU) takes place in a multi-level system with mixed co-financing and shared financial responsibilities. In this paper we analyse how co-financing influences policy-making in regions taking the case of the agri-environmental programme in Saxony-Anhalt. Using an interactive linear programming approach the implications of several co-financing scenarios are analysed. EU co-financing certainly enhances the financial volume for the agri-environmental programme in Saxony-Anhalt; but as regional policy-making is distorted by the scheme of mixed co-financing as compared to unconditional financial transfers, the priorities for measures vary depending on different EU co-financing scenarios.

Cointegrated Vector Autoregression Methods: An Application to Non-Normally Behaving Data on Selected U.S. Sugar-Related Markets
Provedor de dados: 31
Autores: Babula,   Ronald A.; Newman,   Douglas.
The methods of the cointegrated vector autoregression/error correction (VAR/VEC) model are applied to monthly U.S. markets for sugar and for sugar-using markets for confectionary, soft drink, and bakery products. Primarily a methods paper, Johansen and Juselius' methods are applied, with a special focus on addressing well-known issues that preclude statistically normal behavior, and that confront the modelled sugar-based data. In so doing, we illustrate the effectiveness and the benefits of modelling this sugar-related set of markets as a cointegrated system. Perhaps for the first time, cointegrated VEC model results are used to estimate crucial policy-relevant market parameters that drive the markets, as well as to illuminate the dynamic nature of the...

Collaboration in ICT Regulation in the Southern Africa Development Community: A Regional Approach to Capacity Building
Provedor de dados: 31
Autores: Goulden,   Brian; Msimang,   Mandla.
Capacity building is a key activity in ensuring regulatory agencies can fulfil their mandate effectively. Without adequate institutional structures, processes and professional human resources, regulatory agencies are unlikely to be able to act in a credible manner. Lack of credibility impacts adversely on overall effectiveness by diminishing the relationships between the regulator and stakeholders in the regulated sector. This paper provides an overview of the collaboration that has taken place between ICT regulators in the 14 Member States of the Southern Africa Development Community. It indicates the initial approach used and the results that have been achieved through collaboration.

Partnerships can be an extremely effective way to harness additional skills and resources and minimize costs. Collaboration allows scientists (and other partners) to access a broad range of expertise and fosters a multi-disciplinary approach, both of which are often required when tackling complex research issues. However, it may be difficult to make the most of collaborative agreements, since different partners may have different objectives and approaches and misunderstandings can occur.

Collection, Characterization and Use of Genetic Bariation in Chilean Bean Germplasm (Phaseolus vulgaris L.)
Provedor de dados: 113
Autores: Bascur B.,Gabriel; Tay U.,Juan.
Recently performed studies on the type of seed protein present from several origins and their morphological traits have shown that the common bean (Phaseolus vulgaris L.) is native to America, being a species without a specific center of origin and with two areas of domestication: Central America and South America. In this last center, three strains were determined, one of them is called "the Chilean strain", which as noted is a sub-center of genetic diversity for this species. With the purpose of collecting and preserving the genetic diversity present in the Chilean ecotypes, a germplasm collection was made, from Arica to Chiloe, visiting 207 locations in 28 expeditions and collecting 1239 accessions.

This project explored the possible role of collective action among small-scale farmers in managing and maintaining genetic resources in a center of crop diversity. It focused on the local institutions that ensure the supply of seed of diverse maize landraces to small-scale farmers in the Central Valleys of Oaxaca, Mexico. The key hypothesis was that the medium-to-long-term supply of a diverse set of varieties to any individual smallscale maize farmer depends on an agreement among a group of farmers to manage and supply the seed of these landraces to each other, if the need arises, and that this constitutes a form of collective action. Six communities were studied, three of them indepth. Methodologies used included in-depth semi-structured interviews with...

Olson (1965) formulated a "Logic of Collective Action".  We investigate whether a logic of collective action in plant breeding - and research and development generally - can be constructed. Using a case study on the Latin American Fund for Irrigated Rice (FLAR) as well as other real-world institutions of collective action in R&amp;D, we construct an expanded logic of collective action, which revolves around two core features: Impure public goods and the tragedy of the anticommons. Provisions of FLAR and other institutions are related to game theory and contract theory, and theoretical, methodological and policy implications are outlined.

Collective Action in the Management of Common-Pool Resources: Is There an Alternative to the Rational Choice Model?
Provedor de dados: 31
Autores: Gopalakrishnan,   Sathya.
The literature on community based natural resource management largely focuses on developing conditions that enable self-organized groups of resource users to collectively manage common pool resources. The analytical approach in most economic analyses is that of methodological individualism, where hypotheses are based on the representative, rational and self-interested individual who maximizes utility and on the basis of observed attributes of several successful case studies, the theory focuses on creating incentives for collective action through institutional design. This paper argues that an incentive based approach following the rational-choice model of human behavior is not sufficient to explain the success of voluntary groups in overcoming the free...

Autores: Blackman,   Allen.
Colombia's discharge fee system for water effluents is often held up as a model of a well-functioning, economic-incentive pollution control program in a developing country. Yet few objective, up-to-date evaluations of the program have appeared. Based on a variety of primary and secondary evaluative data, this paper finds that that the program has been beset by a number of serious problems including limited implementation in many regions, widespread noncompliance by municipal sewage authorities, and a confused relationship between discharge fees and discharge standards. Nevertheless, in several watersheds, pollution loads dropped significantly after the program was introduced. While proponents claim the incentives that discharge fees created for polluters...

Colonization by Streptococcus agalactiae during pregnancy: maternal and perinatal prognosis
Provedor de dados: 55
Autores: El Beitune,Patrícia; Duarte,Geraldo; Maffei,Cláudia Maria Leite.
We reviewed colonization by group B Streptococcus beta-haemolyticus of Lancefield (SGB), or Streptococcus agalactiae, in pregnant women, and the consequences of infection for the mother and newborn infant, including factors that influence the risk for anogenital colonization by SGB. We also examined the methods for diagnosis and prophylaxis of SGB to prevent early-onset invasive neonatal bacterial disease. At present, it is justifiable to adopt anal and vaginal SGB culture as part of differentiated obstetrical care in order to reduce early neonatal infection. The rates, risk factors of maternal and neonatal SGB colonization, as well as the incidence of neonatal disease, may vary in different communities and need to be thoroughly evaluated in each country...

Colonization of the Corumbá Reservoir (Corumbá River, Paraná River Basin, Goiás State, Brazil) by the "lambari" Astyanax altiparanae (Tetragonopterinae; Characidae)
Provedor de dados: 52
Autores: Dias,Rosa Maria; Bailly,Dayani; Antônio,Rosimeire Ribeiro; Suzuki,Harumi Irene; Agostinho,Angelo Antonio.
This work aimed to determine which population features were important to the colonization process of Astyanax altiparanae in the Corumbá Reservoir. The species presented wide spatial-temporal distribution, caught in all months and sites. Higher CPE values were recorded upstream from the reservoir during the filling phase. In this phase, reproductive activity was intense upstream and moderate in the tributaries. However, a fall in abundance of juveniles was observed after the formation of the reservoir. Among the most relevant population features to grant a successful colonization were wide geographic distribution, ability to occupy and spawn in lentic habitats and feeding flexibility.

COMBATE da vassoura-de-bruxa do cupuaçuzeiro - programa 09. Programa Prosa Rural.
Provedor de dados: 14
O cupuaçuzeiro é uma fruteira típica da região amazônica, cujo fruto tem grande aceitabilidade no mercado regional. O cupuaçu pode ser utilizado na forma de suco, sorvete, doce, compota, geleia e licor. Atualmente são produzidas cerca de 30.000 toneladas do fruto por ano somente no Estado do Pará, que é um dos maiores produtores de cupuaçu do País. Os plantios dessa fruteira na região têm sido atacados pela vassoura-de-bruxa, causada pelo fungo Crinipellis perniciosa. Para combater esta doença, a Embrapa Amazônia Oriental (Belém-PA) lançou quatro clones de cupuaçuzeiros tolerantes à vassoura-de-bruxa: Belém, Codajás, Coari e Manacupuru. Eles garantem uma plantação com elevada produtividade, apresentando maior número de frutos por planta e maior rendimento...

Combination of diatomaceous earth and powder deltamethrin for insect control in stored corn
Provedor de dados: 92
Autores: Ceruti,Fabiane Cristina; Lazzari,Sonia Maria Noemberg.
The use of diatomaceous earth (DE) is a very efficient insect control measure in stored grain IPM due to its low cost, easy application, reduction of active ingredient residues, lower environmental contamination and operator safety. The objective of this research was to evaluate the efficacy of different dosages of DE mixed with powder deltamethrin for controlling Sitophilus zeamais in stored corn. Samples of 100 g of clean and dry corn, in three replicates, were submitted to the following treatments: DE (Keepdry®), at the dosages of 500, 750 and 1000 g/t; powder deltamethrin (K-Obiol®) at 0,5 g a.i. /t and 1,0 g a.i. /t; and combinations of the lowest and highest DE dosages with the two dosages of deltamethrin.

Combination of different methods for direct control of Vicia hirsuta in winter wheat
Provedor de dados: 21
Autores: Lukashyk, Pavel; Koepke, Ulrich.
Combinations of three different direct methods for controlling Vicia hirsuta (kainite application, flame weeding and harrowing) were investigated in field experiments. They were based on different strategies at early growth stages of V. hirsuta and standardised harrowing at late growth stages. The highest efficacy of kainite application and flame weeding was achieved at the one leaf stage of V. hirsuta. Winter wheat regeneration from damage caused by both kainite and thermal control was satisfactory when treatments were applied at early growth stages (GS 23). Vicia hirsuta plants that survived kainite application or flame weeding were successfully controlled by repeated harrowing at later crop growth stages; crop growth was not affected. Seed production of...

Provedor de dados: 55
Autores: Beck,S. T.; Leite,O. M.; Arruda,R. S.; Ferreira,A. W.
Two recombinant antigens and a crude bacterial antigen of a wild M. tuberculosis strain were used to detect specific IgG antibodies in sera from 52 patients with pulmonary tuberculosis, confirmed by an acid-fast smear and serum culture of these patients and that of 25 contacts. The patients were not infected with HIV. We evaluated the sensitivity and specificity of ELISA, based on the recombinant TbF6® and TbF6/DPEP antigen and a search for reactivity patterns in the Western blot technique, using whole mycobacterium antigen. Serum samples from 22 healthy individuals and from 30 patients with lung diseases other than tuberculosis were used as controls. The best ELISA results were obtained with the TbF6/DPEP antigen combination, which gave 85% sensitivity...

Combining indicator trends to assess ongoing changes in exploited fish communities: diagnostic of communities off the coasts of France
Provedor de dados: 5

We present a method for combining individual indicator results into a comprehensive diagnostic of fishing impacts on fish populations and communities. A conceptual framework for interpreting combined trends in a set of simple indicators is proposed, relying beforehand on qualitative expectations anchored in ecological theory. The initial state of the community is first assessed using published information. Which combinations of trends are acceptable or undesirable is decided, depending on the initial status. The indicators are then calculated from a time-series and their time trends are estimated as the slopes of linear models. Finally, the test results are combined within the predefined framework, providing a diagnostic on the dynamics of fishing impacts...

Combining on-farm, participatory research methodologies with modelling in order to create a regionally based organic agriculture in Holland
Provedor de dados: 21
Autores: Prins, Udo; de Wit, Jan; Nauta, Wytze.
Like conventional farming, organic agriculture in the Netherlands is highly specialized. Both livestock and arable farmers have optimised production independent of each other which has led to a high use of external inputs from conventional agriculture (manure and other fertilisers and straw) and feedstuffs (mainly concentrate feed) from abroad. This situation conflicts with important principles of organic agriculture such as a balance between livestock and arable farming, closing nutrient cycles and regionally based production. In an attempt to find solutions for this dilemma, the Louis Bolk Institute (LBI) started with a series of projects called “Partner Farms” in which the LBI cooperated closely with leading edge farmers (Wit et al, 2003). In these...

Comet assay comparison of different Corbicula fluminea (Mollusca) tissues for the detection of genotoxicity
Provedor de dados: 74
Autores: Rigonato,Janaina; Mantovani,Mário Sérgio; Jordão,Berenice Quinzani.
The comet assay was used to study the sensitivity of the widely distributed freshwater bivalve mollusk Corbicula fluminea to the DNA-damaging alkylating-agent methylmethane sulfonate (MMS). This study was undertaken to ascertain if C. fluminea is a good bioindicator of pollutants in aquatic environments and identify which C. fluminea tissue is most effective and practical for genotoxicity studies. The mollusks were exposed to 0.6, 1.2 or 2.4 X 10-4 M MMS for 40 min and their hemolymph, gill tissue and digestive gland tissue assessed for the level of DNA damage and the time needed for the tissues to recovery. Regression analysis showed a direct linear dose-response relationship between MMS concentration and the number of damaged cells for hemolymph and...
