10-year interdisciplinary monitoring of organic stocklass, vegetable rotations at Warwick-HRI, Kirton, South Lincolnshire, UK
Provedor de dados: 21
Autores: Schmutz, U; Rayns, F; Sumpton, P.
Interdisciplinary monitoring of an organic stockless farming system has been carried out over ten years on a fertile silty clay loam in the main vegetable production area of the UK. The results draw together economic outcomes with agronomy, soil science and agro-ecology. Organic management has been used at the Kirton research site since conversion of a 3.2 ha unit in 1997. There is great variability in crop yields and marketing results but overall a successful ongoing vegetable production system has been established. Soil fertility, weeds, pests and diseases have been managed successfully without imports of animal manures or green waste compost. Production costs are well controlled and marketable yields are good. However, because the site is a research...

15N-labed glycine synthesis
Provedor de dados: 42
Autores: Tavares,Claudinéia R.O.; Bendassolli,José A.; Coelho,Fernando; Sant'ana Filho,Carlos R.; Prestes,Clelber V.
This work describes a method for 15N-isotope-labeled glycine synthesis, as well as details about a recovery line for nitrogen residues. To that effect, amination of alpha-haloacids was performed, using carboxylic chloroacetic acid and labeled aqueous ammonia (15NH3). Special care was taken to avoid possible 15NH3 losses, since its production cost is high. In that respect, although the purchase cost of the 13N-labeled compound (radioactive) is lower, the stable tracer produced constitutes an important tool for N cycling studies in living organisms, also minimizing labor and environmental hazards, as well as time limitation problems in field studies. The tests were carried out with three replications, and variable 15NH3(aq) volumes in the reaction were used...

2006 Global Hunger Index: A Basis for Cross-Country Comparisons
Provedor de dados: 31
Autores: Wiesmann,   Doris M.
Indices can be powerful tools for international monitoring and advocacy, and if used in international rankings, can help foster a sense of healthy competition among countries. With this in mind, IFPRI's Global Hunger Index (GHI) was designed to help mobilize political will and promote good policies by ranking countries and illustrating trends. It captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality, which is to a large extent attributable to undernutrition. Accordingly, the index includes the following three equally weighted indicators: the proportion of people who are food energy deficient as estimated by the Food and Agriculture Organization of the United Nations,...

2006 NORTH DAKOTA AGRICULTURAL OUTLOOK: REPRESENTATIVE FARMS, 2006-2015
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.; Swenson,   Andrew L.
Net farm income for nearly all representative farms in 2015 is projected to be higher than in 2005.  Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income.  Commodity prices and yields are projected to increase slightly faster than costs, which will increase net farm income.  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 farms are expected to increase throughout the forecast period.

2006 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS, 2005-2015
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2005-2015 using the Global Sugar Policy Simulation Model.  This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to improve over the next 10 years, mainly because higher world oil prices have increased the conversion of sugar into ethanol by Brazil. Brazil is the largest exporter of sugar, and it is expected that Brazilian sugar exports may be reduced due to high oil prices.  World demand for sugar is expected to grow faster than world supply, resulting in Caribbean sugar prices increasing from 11.35 cents/lb in 2005 to 18.05 cents/lb in...

2006 OUTLOOK OF THE U.S. AND WORLD WHEAT INDUSTRIES, 2005-2015

Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world wheat markets for the 2005-2015 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 current higher price levels in 2006 are due to weather conditions and will not be maintained, as production is expected to return to normal levels in 2007.  World trade volumes of both classes of wheat are expected...

2006 PRECISION AGRICULTURAL SERVICES DEALERSHIP SURVEY RESULTS
Provedor de dados: 31
Autores: Whipker,   Linda D.; Akridge,   Jay T.
Precision technologies are now well-integrated into the agricultural industry - both at the farm level and at the crop input dealer level.  No longer are crop input dealers only using the technologies to bring new services to their customers, they are also utilizing the technology in their own businesses to improve the efficiency and effectiveness of their business operations.  In early 2006, Crop Life magazine and Purdue University's Center for Food and Agricultural Business conducted a survey for the 11th consecutive year to assess the adoption of precision agriculture practices in the U.S. from the perspective of the retail crop input dealer.  The questionnaire was sent to 2500 retail crop input dealerships across the U.S.  A total of 368 questionnaires...

2-D and 3-D modelling of wide-angle seismic data: an example from the Voring volcanic passive margin
Provedor de dados: 5
Autores: Rouzo, Stephane; Klingelhoefer, Frauke; Jonquet Kolsto, Hélène; Karpuz, Ridvan; Kravik, Karl; Mjelde, Rolf; Murai, Yoshio; Raum, Thomas; Shimamura, Hideki; Williamson, Paul; Geli, Louis.
This study presents the modelling of 2-D and 3-D wide-angle seismic data acquired on the complex, volcanic passive margin of the Voring Plateau, off Norway. Three wide-angle seismic profiles were shot and recorded simultaneously by 21 Ocean Bottom Seismometers, yielding a comprehensive 3-D data set, in addition to the three in-line profiles. Coincident multi-channel seismic profiles are used to better constrain the modelling, but the Mesozoic and deeper structures are poorly imaged due to the presence of flood basalts and sills. Velocity modelling reveals an unexpectedly large 30 km basement high hidden below the flood basalt. When interpreted as a 2-D structure, this basement high produces a modelled gravity anomaly in disagreement with the observed...

A 27 kyr terrestrial biomarker record in the southern Indian Ocean
Provedor de dados: 5
Autores: Sicre, Marie-alexandrine; Labeyrie, Laurent; Ezat, Ullah; Mazaud, Alain; Turon, Jean-louis.
Terrestrial inputs were reconstructed using high molecular weight n-alkane concentrations recorded in the sub-Antarctic Indian Ocean core MD94-103 (45 degrees 35'S, 86 degrees 31'E, 3560 m) to examine regional changes in the atmospheric circulation over the last 27 kyr. This record was compared to the dust content of EPICA-Dome C ice and continental data from South Africa ( e. g., pollen sequences and isotope records in speleothems) to get a comprehensive understanding of atmospheric links between low and midlatitudes of the Indian Ocean. Terrestrial n-alkanes indicate higher glacial than Holocene inputs and marked glacial oscillations. Minimum values during the Last Glacial Maximum (LGM) are consistent with colder and drier climate and presumably caused...

A Battle of Taste and Environmental Convictions for Ecolabeled Seafood: A Contingent Ranking Experiment
Provedor de dados: 31
Autores: Johnston,   Robert J.; Roheim,   Cathy A.
Consumers face pressure from environmental groups to modify their seafood purchase decisions based on concerns about fisheries' production practices. Existing research provides little information indicating whether seafood consumers are willing to change purchasing behavior based on a product's environmental attributes, to the exclusion of other attributes. We describe a contingent ranking experiment addressing preferences for fresh seafood, allowing for choices among different species, some displaying an ecolabel. Results suggest consumers consider overfishing sufficiently important to contemplate changing the species of fish they buy; however, they are unwilling to choose a less-favored species based solely on the presence of an ecolabel.

A Bayesian Approach to the Estimation of Environmental Kuznets Curves for CO2 Emissions
Provedor de dados: 31
Autores: Mazzanti,   Massimiliano; Musolesi,   Antonio; Zoboli,   Roberto.
This paper investigates the EKC curves for CO2 emissions in a panel of 109 countries during the period 1959-2001. The length of the series makes the application of a heterogeneous estimator suitable from an econometric point of view. The results, based on the hierarchical Bayes estimator, show that different EKC dynamics are associated with the different sub samples of countries considered. On average, more industrialized countries show an EKC evidence in quadratic specifications, which are nevertheless probably evolving into an N shape, emerging from cubic specifications. Less developed countries consistently show that CO2 emissions still rise positively with income, though some signals of an EKC path arise.

A Bioeconomic Analysis of Protected Area use in Fisheries Management
Provedor de dados: 31
Autores: Greenville,   Jared W.; MacAulay,   T. Gordon.
The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between environments within the fishery. Differing levels of management control over fishery resource extraction are analysed. The model is applied to Manning Bioregion in NSW. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery.

A Brief Agrarian History of the Cottonwood River Watershed in Southwestern Minnesota
Provedor de dados: 31
Autores: Petrolia,   Daniel R.
The Cottonwood River Watershed is located in southwestern Minnesota, draining 1,310 square miles of land within the Minnesota River Basin.  The watershed is comprised of parts of Brown, Cottonwood, Lyon, Murray, and Redwood Counties.  This essay gives a brief account of the initial European settlement of the area and the establishment of the current political boundaries.  It then focuses on the major developments in agricultural production during the past 150 years, touching on the changes in landscape and wildlife due to drainage and restructuring of water bodies and the clearing of forest land.

A case study of changes in economic performance of an irrigated dairy farm in northern Victoria
Provedor de dados: 31
Autores: Ho,   Christie K.M.; Malcolm,   Bill; Armstrong,   Dan P.; Doyle,   Peter T.
Average total factor productivity measures for the dairy industry provide an insight into how the industry is performing as a whole, but reveal little about what may be happening on individual farms. A case study of an irrigated dairy farm in northern Victoria, over a 37-year period, found that total milk production and some measures of partial productivity increased substantially. The economic performance of this case study farm over the 37-year period is described and analysed. From records of income and expenses, operating profit, returns to capital, labour and management and total productivity measures were calculated. Between 1980 and 2000, the business achieved productivity gains at higher than the rate estimated for the whole industry. This...

A century of research on the classical locality of Tegelen (province of Limburg, The Netherlands)
Provedor de dados: 16
Autores: Hoek Ostende, L.W. van den; Vos, J. de.
In 1904 Eugène Dubois published the first report on fossil mammals from the vicinity of Tegelen. After a century of research the clay-pits from the area are known as a classical locality for Villafranchian mammals. Antje Schreuder's work was particularly important for making the fossils from Tegelen known. Her papers, however, also indicate some problems. The large mammal fossils were gathered by clay-workers in the local ceramic industry, and the fragmentary nature of the fossils is partly caused by injudicious handling while extracting the bones from the clay. Because the Tegelen fossils are chance finds rather than the results of careful excavations, their exact provenance is not established. The only exception is the collection of micromammals, which...

In this study, we employ the Harbinson proposal and July Framework to compare a ‘likely’ Doha scenario with an ‘inclusive’ baseline. The key aim is to assess the impacts across EU member states. More specifically, we (i) employ the latest version 6 of the GTAP database, (ii) explicitly model CAP mechanisms (e.g., quotas, decoupled payments, set-aside, CAP budget etc.) to more accurately assess the asymmetric trade led welfare effects on selected EU member states, and (iii) introduce binding overhangs into domestic support, export subsidies and more importantly market access commitments. Whilst the EU regions benefit from the multilateral reform proposals, the gains are weakened considerably by the tariff binding overhangs, where the EU25 only gain ten per...

A Comparative Analysis of Production and Marketing of Bt Cotton and Hybrid Cotton in Saurashtra Region of Gujarat State
Provedor de dados: 31
Autores: Visawadia,   H.R.; Fadadu,   A.M.; Tarpara,   V.D.
The study has revealed that the total cost per hectare is higher in Bt cotton than hybrid cotton. The cost of seeds has been found higher in Bt cotton, whereas hybrid cotton growers incur more cost on insecticides/ pesticides. This shows the effectiveness of the new technology (Bt cotton) for insect resistance. The average total cost of production as well as the bulk line cost have been found lower in Bt cotton. This depicts a reduction in the unit cost of Bt cotton, which is the distinct advantage of the new technology. A higher yield of 29 per cent has been obtained by the Bt cotton farmers over the hybrid cotton growers. The study has identified the constraints in production, and marketing of Bt cotton in the area. Bt cotton has been found a superior...

A Comparative Evaluation of Cash Flow and Batch Profit Hedging Effectiveness in Commodity Processing
Provedor de dados: 31
Autores: Dahlgran,   Roger A.
Agribusinesses make long-term plant-investment decisions based on discounted cash flow.  It is therefore incongruous for an agribusiness firm to use cash flow as a plant-investment criterion and then to completely discard cash flow in favor of batch profits as an operating objective.  This paper assumes that cash flow and its stability are important to commodity processors and examines methods for hedging cash flows under continuous processing.  Its objectives are (a) to determine how standard hedging models should be modified to hedge cash flows, (b) to outline the differences between cash flow hedging and profit hedging, and (c) to determine the effectiveness of hedging in reducing cash flow variability.  A cash flow hedging methodology is developed....

Organic Animal Farming (OAF) systems hold a major part in Organic Agriculture (OA). Alternative protein crops are essential in the development of OAF in order to substitute technically and economically non-acceptable protein sources in Organic Animal feeding.   A study, aiming to compare white lupine (Lupinus albus cv Multitalia) and fava bean (Vicia faba cv Vesuvio) crops, was undertaken in Central Greece. The study compared the two plant species under organic or conventional management regimes in terms of quantity and quality produced. There were no productivity or quality differences between the regimes.

A comparison of cultivation and wild collection of medicinal and aromatic plants under sustainability aspects
Provedor de dados: 26
Autores: Schippmann, U.; Leaman, D.; Cunningham, A.B.
With the increased realization that many wild medicinal and aromatic plant (MAP) species are being over-exploited, a number of agencies are recommending that wild species be brought into cultivation systems. Others argue sustainable harvest to be the most important conservation strategy for most wild-harvested species, given their contributions to local economies and their greater value to harvesters over the long term. Besides poverty and the breakdown of traditional controls, the major challenges for sustainable wildcollection include: lack of knowledge about sustainable harvest rates and practices, undefined land use rights and lack of legislative and policy guidance.

A Comparison of the Effect of Chlorhexidine, Tap Water and Normal Saline on Healing Wounds
Provedor de dados: 77
Autores: Salami,Ayodeji A; Imosemi,Innocent O; Owoeye,Olatunde O.
Many researchers have advocated in recent times that antiseptic use in healing wounds should be discouraged. Antiseptics have been found to retard healing of wounds. Innocuous solutions like normal saline and tap water are being considered as better alternatives to antiseptics. Chlorhexidine, a commonly used antiseptic, is known to be less toxic on granulation cells. We decided to compare the effect of chlorhexidine, normal saline and tap water on healing wounds. Three groups of wistar rats had 2 by 2cm full thickness wounds made on their right dorsolateral flanks. The wounds were dressed with either chlorhexidine, normal saline or tap water. Wounds were examined at three-day intervals and measurements of area covered were taken on the first day of study...

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

A Continuous Multi-dimensional Measure of Rurality: Moving Beyond Threshold Measures
Provedor de dados: 31
Autores: Waldorf,   Brigitte S.
This paper introduces the Index of Relative Rurality, a continuous measure of rurality.  The index is based on four dimensions: population size, density, percentage of urban residents, and distance to the closest metropolitan area. The index varies from 0 (most urban) to 1 (most rural). Compared to existing means of measuring rurality, the index is continuous and thus does not suffer from problems that arise when using arbitrary thresholds to separate discrete categories.  This shift away from often ill-defined categories of rural and urban, to measuring the degree of rurality will shed new light on a wide array of rural issues ranging from rural poverty to economic growth. This paper shows that the Index of Relative Rurality makes an invaluable...

Autores: Ganiere,   Pierre; Chern,   Wen S.; Hahn,   David E.
A national telephone survey was conducted in the United States in April 2002 to study the consumer acceptance of genetically modified (GM) foods. Attitudes toward GM foods were examined through the use of a multiple correspondence analysis (MCA), analyzing the interrelationships among many categorical variables. This method was combined with a cluster analysis to construct a typology of consumers' attitudes. Four distinct classes of attitudes were finally extracted, denoted as: Proponents, Non-Opponents, Moderate Opponents, and Extreme Opponents. It was estimated that only 35% of the surveyed population was opposed to GM foods.

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

First, the paper develops a methodology to specify and estimate cost-minimizing input decisions under a state-contingent technology. Second, the analysis is applied to time series data on US agriculture. It finds strong empirical evidence that, in the analysis of input choices, expected output alone does not provide an appropriate representation of production uncertainty. The results provide empirical support for an output-cubical technology. This indicates that an ex post analysis of stochastic technology (as commonly found in previous research) appears appropriate. The analysis also provides...

A cost-effective melting temperature assay for the detection of single-nucleotide polymorphism in the MBL2 gene of HIV-1-infected children
Provedor de dados: 56
Autores: Arraes,L.C.; de Souza,P.R.; Bruneska,D.; Castelo Filho,A.; de Souza Cavada,B.; de Lima Filho,J.L.; Crovella,S.
We report a fast (less than 3 h) and cost-effective melting temperature assay method for the detection of single-nucleotide polymorphisms in the MBL2 gene. The protocol, which is based on the Corbett Rotor Gene real time PCR platform and SYBR Green I chemistry, yielded, in the cohorts studied, sensitive (100%) and specific (100%) PCR amplification without the use of costly fluorophore-labeled probes or post-PCR manipulation. At the end of the PCR, the dissociation protocol included a slow heating from 60º to 95ºC in 0.2ºC steps, with an 8-s interval between steps. Melting curve profiles were obtained using the dissociation software of the Rotor Gene-3000 apparatus. Samples were analyzed in duplicate and in different PCR runs to test the reproducibility of...

A Cost-Effectiveness Study of Animal Disease Eradication Strategies: Foot-and-Mouth Disease in Ireland
Provedor de dados: 31
Autores: Dillon,   Emma J.
The primary focus of this poster paper is to evaluate the cost-effectiveness of alternative control strategies for a number of simulated outbreaks of Foot-and-Mouth disease (FMD) in four agriculturally diverse Irish regions, examining for the first time, the potential role of emergency vaccination in the country. With the increasing threat of transboundary animal diseases due to globalisation, wider market integration and increased animal movement it is important that such an evaluation of control and eradication strategies be undertaken and contingency plans be put in place. The new EU Directive (2003/85/EC) on FMD control permits the use of emergency vaccination as part of an FMD control strategy. The slaughter of infected animals and "dangerous...

A Critical Account of the Relationship between Institutional Trust, Risk Perception, and Technology Acceptance with an Application to Genetically  Modified Foods
Provedor de dados: 31
Autores: Boecker,   Andreas; Nocella,   Giuseppe.
This article critically reflects on the widely held view of a causal chain with trust in public authorities impacting technology acceptance via perceived risk. It first puts forward conceptual reason against this view, as the presence of risk is a precondition for trust playing a role in decision making. Second, results from consumer surveys in Italy and Germany are presented that support the associationist model as counter hypothesis. In that view, trust and risk judgments are driven by and thus simply indicators of higher order attitudes toward a certain technology which determine acceptance instead. The implications of these findings are discussed.

A critical evaluation of the effect of population size and phenotypic measurement on QTL detection and localization using a large F2 murine mapping population
Provedor de dados: 74
Autores: Li,Xinmin; Quigg,Richard J; Zhou,Jian; Xu,Shizhong; Masinde,Godfred; Mohan,Subburaman; Baylink,David J.
Population size and phenotypic measurement are two key factors determining the detection power of quantitative trait loci (QTL) mapping. We evaluated how these two controllable factors quantitatively affect the detection of QTL and their localization using a large F2 murine mapping population and found that three main points emerged from this study. One finding was that the sensitivity of QTL detection significantly decreased as the population size decreased. The decrease in the percentage logarithm of the odd score (LOD score, which is a statistical measure of the likelihood of two loci being lied near each other on a chromosome) can be estimated using the formula 1 - n/N, where n is the smaller and N the larger population size. This empirical formula has...

A cross-cultural study of cereal foods' quality perception
Provedor de dados: 31
Autores: Krutulyte,   Rasa; Costa,   Ana I.; Grunert,   Klaus G.
Cereal foods' production and use show substantial heterogeneity across Europe. For a category central in most EU diets, cereal foods' quality perception is, nevertheless, surprisingly understudied. With this in mind, 357 Danish, Lithuanian and Portuguese citizens were inquired about the importance of several cues and dimensions in their evaluation of the perceived quality of bread, cookies, breakfast cereals, pasta and vodka. Portuguese and Lithuanians consistently gave a significantly higher average importance to all the cues and quality dimensions considered, for all products, than their Danish counterparts. Nevertheless, respondents in all three samples found expected quality dimensions to be much more important than both extrinsic and intrinsic cues...

A Determination of the Trade Creation and Diversion Effects of Regional Trade Agreements in the Western Hemisphere
Provedor de dados: 31
Autores: Hilbun,   Brian M.; Kennedy,   P. Lynn; Dufour,   Elizabeth Anne.
With the recent proliferation of Regional Trade Agreements (RTAs) the tendency world-wide has been seemingly toward trade liberalization.  This thesis is primarily concerned with the impacts RTAs have had in the Western Hemisphere regarding agricultural trade flows.  Utilizing the framework of the Gravity Model, agricultural trade flows for 24 Western Hemisphere Nations were examined. In the course of the study it was expected that if RTAs were to have an effect it would be a positive Trade Creation Effect and a negative Trade Diversion Effect with positive effects for GDP of importer/exporter and population size of importer/exporter and a negative effect for that of distance.  Of the five agreements examined (NAFTA, AC, MERCO, LAIA, and CACM), NAFTA and...

A distinctive new cloud-forest rodent (Hystricognathi: Echimyidae) from the Manu Biosphere Reserve, Peru
Provedor de dados: 81
Autores: Patterson,Bruce D.; Velazco,Paul M.
Recent surveys in Peru 's Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of "brush-tailed tree rats" previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. While the inclusion of the new taxon does not resolve the "star phylogeny" which underlies the echimyid radiation, it identifies the Andes as a possible theatre for the evolution of some soft-haired members of the group. The new species is described and a revised diagnosis of the...

A Double Hurdle Model of Preferences for a Proposed Capacity Reduction Program in the Atlantic Shark Fishery
Provedor de dados: 31
Autores: Musengezi,   Jessica D.; Rossi,   Frederick J.; Larkin,   Sherry L.
The Atlantic shark fishery is considered to be overcapitalized. One approach to capacity management is the purchase and permanent retirement of fishing vessels, fishing permits, or both under voluntary buyback programs. Representatives of the commercial shark fishery have proposed such an approach to manage the overcapacity in their fishery in the Gulf of Mexico and Atlantic regions. This program would allow owners to submit willingness-to-accept (WTA) bids for their permits and vessels. This study uses econometric modeling to explain the potential participation and bid amounts from a survey of permit owners.

A double-hurdle model of Irish households' foodservice expenditure patterns
Provedor de dados: 31
Autores: Keelan,   Conor D.; Henchion,   Maeve M.; Newman,   Carol F.
The aim of this paper is to analyse the various factors fuelling demand for Food- Away - From- Home (FAFH) in Ireland. The two largest components of this industry, the quick- service sector (fast food and takeaway) and the full- service sector (hotel and restaurant meals), are analysed using the most recently available Household Budget Survey data for Ireland. The results from a Box- Cox double hurdle model indicate that different variables affect expenditure in the different sectors in different ways. Income has a greater effect on full- service expenditure than on quick- service. Similarly households that are healthconscious indicate a greater preference for full- service meals while households with higher time values indicate a greater preference for...

Bathymodiolus azoricus and Bathymodiolus puteoserpentis are symbiont-bearing mussels that dominate hydrothermal vent sites along the northern Mid-Atlantic Ridge (MAR). Both species live in symbiosis with two physiologically and phylogenetically distinct Gammaproteobacteria: a sulfur-oxidizing chemoautotroph and a methane-oxidizer. A detailed analysis of mussels collected from four MAR vent sites (Menez Gwen, Lucky Strike, Rainbow, and Logatchev) using comparative 16S rRNA sequence analysis and fluorescence in situ hybridization (FISH) showed that the two mussel species share highly similar to identical symbiont phylotypes. FISH observations of symbiont distribution and relative abundances showed no obvious differences between the two host species. In...

A DYNAMIC ANALYSIS OF SUSTAINABLE FARMING SYSTEMS IN CALIFORNIA AGRICULTURE
Provedor de dados: 31
Autores: Wicks,   Santhi; Howitt,   Richard E.; Klonsky,   Karen.
The economic viability of alternative and more sustainable agriculture farming systems depend on the value of farm profits. These values may be estimated through short or long-run of profit maximization, but there is a difference in these methods. In short-run profit maximization the instantaneous marginal benefits are equated to the marginal costs of production. Where as in the long-run maximization of profits the capital value of soil resources are quantify in addition to the direct revenues and costs of each system over time. A long-run approach is fundamental to capture the value of capital improvements in soil resources. In this study we use short-run experimental data from SAFS's rotations to calibrate the crop simulation model EPIC, and obtain a...

A Dynamic Bioeconomic Model of Ivory Trade: Details and Extended Results
Provedor de dados: 31
Autores: van Kooten,   G. Cornelis.
Trade in ivory is banned under CITES in an effort to protect the African elephant. The trade ban is supported by some range states, most notably Kenya, because they see the ban as an effective means for protecting a ‘flagship’ species, one that attracts tourists and foreign aid. It is opposed by some states, mainly in southern Africa, because their elephant populations are exceeding the capacity of local ecosystems with culling and other sources have resulted in the accumulation of large stocks of ivory. They argue that ivory trade will benefit elephant populations. The question of whether an ivory trade ban will protect elephant populations is addressed in this paper using a dynamic partial-equilibrium model that consists of four ivory exporting regions...

A Dynamic Model of U.S. Sugar-Related Markets: A Cointegrated Vector Autoregression Approach
Provedor de dados: 31
Autores: Babula,   Ronald A.; Newman,   Douglas; Rogowsky,   Robert A.
The methods of the cointegrated vector autoregression (VAR) 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, we apply Johansen and Juselius' advanced procedures to these markets for perhaps the first time, with focus on achievement of a statistically adequate model through analysis of a battery of advanced statistical diagnostic tests and on exploitation of the system's cointegration properties through rank restrictions, statistically supported hypotheses test restrictions, and inference. The VEC model results illuminate the estimates of crucial policy-relevant market parameters that drive these markets, as well as the dynamic nature of the...

A Dynamic Principal-Agent Model of Human-Mediated Aquatic Species Invasions
Provedor de dados: 31
Autores: MacPherson,   Alexander J.; Moore,   Rebecca; Provencher,   Bill.
This paper presents a dynamic principal-agent model of aquatic species invasions in which a manager, concerned about the spread of invasive species across lakes by boaters, sets interseasonal management controls on a lake-by-lake basis, and boaters make a series of intraseasonal trip decisions to maximize random utility during the course of the season, conditional on the controls imposed by the manager. The results of a simulated invasion of Eurasian watermilfoil (Myriophyllum spicatum) highlight interesting aspects of the optimal management policies under two different management objectives: maximizing boater welfare and minimizing milfoil spread.

A Dynamic Risk Optimization Model for Evaluating Profitable and Feasible Water Management Plans
Provedor de dados: 31
Autores: Grove,   Bennie; Oosthuizen,   L.K.; Backeberg,   G.R.
Currently the South African government is advocating the cultivation of high valued crops and more efficient use of available water resources through the adoption o f more efficient irrigation technology and irrigation scheduling. A requirement of the National Water Act (Act 36 of 1998) is the compilation of water management plans. The main objective of this paper is to develop a multiperiod mathematical risk programming model able of assisting water user associations with the compilation of water management plans that are both profitable and feasible. Special care was taken to represent canal capacities and irrigation system application rates in the model. Risk simulation procedures are used to generate an appropriately correlated inter- and...

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

A flow cytometric approach to study intracellular-free Ca2+ in Crassostrea gigas haemocytes
Provedor de dados: 5
Autores: Aton, Emilie; Renault, Tristan; Gagnaire, Beatrice; Thomas Guyon, Hélène; Cognard, C; Imbert, N.
Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium.   Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were...

A formação da ALCA e os prováveis efeitos sobre as exportações agrícolas brasileiras
Provedor de dados: 123
Autores: Fonsêca,Márcia Batista da; Hidalgo,Álvaro Barrantes.
Na última década do século XX, os principais empreendimentos de integração com que o Brasil se envolveu foram o Mercado Comum do Sul (MERCOSUL) e as negociações em torno da formação da Área de Livre Comércio das Américas (ALCA). A integração regional junto com a liberalização comercial beneficiou profundamente o setor agrícola brasileiro e hoje o país apresenta-se no cenário da ALCA como o segundo maior exportador de produtos agrícolas do bloco. Os efeitos provocados sobre o comércio estão relacionados diretamente às restrições comerciais antes impostas aos parceiros e ao volume de comércio inicialmente verificado entre esses países. Tendo em vista esse aspecto, o objetivo deste estudo é o de conhecer os prováveis efeitos da participação do Brasil na ALCA...

A four-year comparison of two organic dairy systems
Provedor de dados: 21
Autores: Weller, Mr Richard.
Two organic systems were studied, the first based on self-sufficiency (SS) and the feeding of high-forage diets, and the second on purchased concentrates (PC) and maximising milk output. The growing of both concentrate and forage feeds in the SS system reduced the stocking density. Feeding high-forage diets increased the proportion of milk produced from forage but decreased the energy concentration of the ration, leading to lower milk persistency, reduced milk protein in early lactation and reduced pregnancy rates. In the PC system importing feed increased the stocking density but also increased the ‘farm-gate’ nutrient surpluses.

The framework allows comprehensive and consistent measurement and classification of U.S. domestic support to 2015 under different assumptions. Projections of future U.S. domestic support patterns are made with estimates published in the USDA Agricultural Baseline Projections. We also use information from the OECD, FAPRI, NASS, and our own estimates. We present key elements and an overview of our analytical framework, assumptions of a baseline scenario, and some analytical results and observations arising from our analysis. The baseline scenario extends the classification of programs in WTO notifications to 2015. The framework consists of 65 spreadsheets, which are grouped into 4 analytical stages: calculation of program estimates by commodity; calculation...

Many populations of wild animals and plants are declining and face increasing threats from habitat fragmentation and loss as well as exposure to stressors ranging from toxicants to diseases to invasive nonindigenous species. We describe and demonstrate a spatially explicit ecological risk assessment that allows for the incorporation of a broad array of information that may influence the distribution of an invasive species, toxicants, or other stressors, and the incorporation of landscape variables that may influence the spread of a species or substances. The first step in our analyses is to develop species models and quantify spatial overlap between stressor and target organisms. Risk is assessed as the product of spatial overlap and a hazard index based...

Autores: Cortes-Jimenez,   Isabel; Pulina,   Manuela.
Nowadays many developing countries focus on economic policies for promoting international tourism and exports expansion as a potential source of economic growth of the country. However, the understanding of the relationship between exports and economic growth is still ongoing. When treating the relationship between tourism and economic growth, considering tourism as a non-traditional export few studies have been published to date. This paper has the objective to assess if exports and tourism have really promoted growth by means of the export-led growth hypothesis (ELGH) and the tourism-led growth hypothesis (TLGH). The cases under analysis are Spain and Italy, two of the most important countries worldwide regarding the expansion of tourism. Cointegration...

A Future for the Dead Sea Basin: Water Culture among Israelis, Palestinians and Jordanians
Provedor de dados: 31
Autores: Lipchin,   Clive.
The Dead Sea basin plays a major role for regional economic development (industry, tourism and agriculture) in the Middle East. This potential is threatened by the steady disappearance of the Dead Sea. Since around 1930 the water level of the Dead Sea has fallen by about 25 m, about half of this alone in the last 20 years. The Dead Sea is a transboundary resource shared by Israel, the Palestinian Authority and Jordan. The Dead Sea is the terminal point of the Jordan River watershed and as such, it serves as a barometer for the health of the overall system. Its rapid decline reflects the present water management strategies of the riparian and upstream countries. This includes the different water cultures of the three countries.  Throughout history, the Dead...

A gap analysis of confined field trial application forms for genetically modified crops in East Africa: evaluating the potential for harmonization
Provedor de dados: 31
Autores: Linacre,   Nicholas A.; Cohen,   Joel I.
The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo...

A General Equilibrium Analysis of Foreign and Domestic Demand Shocks Arising from Mad Cow Disease in the United States
Provedor de dados: 31
Autores: Devadoss,   Stephen; Holland,   David W.; Stodick,   Leroy; Ghosh,   Joydeep.
The discovery of the first case of mad cow disease in the United States in 2003 reverberated across the beef and cattle industry. This study employs a general equilibrium model to analyze the potential economic effects of mad cow disease on the beef, cattle, and other meat industries under three scenarios, ranging form most favorable to most pessimistic. The scenario with 90% foreign demand decline and 10% domestic demand reduction generates results consistent with the actual outcomes after the mad cow disease outbreak. Only if domestic demand declines significantly will the economic hardship in the U.S. beef and cattle industry be very large.

A Global Hunger Index: Measurement Concept, Ranking of Countries, and Trends
Provedor de dados: 31
Autores: Wiesmann,   Doris M.
Progress in combating hunger and undernutrition has been lagging for decades. Best practices to fight hunger and undernutrition have been available for a long while, but lack of political will among leaders and a lack of political power among the poor have hampered their implementation. Since indices have proven to be powerful tools for advocacy and are able to capture multifaceted phenomena, the Global Hunger Index (GHI) was developed to increase attention to the hunger problem and mobilize the political will to speed up urgently needed progress in the fight against hunger. The GHI captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality, which is to a large extent...

This paper is a work-in-progress account of ideas and propositions about resilience in social-ecological systems. It articulates our understanding of how these complex systems change and what determines their ability to absorb disturbances in either their ecological or their social domains. We call them &amp;#8220;propositions&amp;#8221; because, although they are useful in helping us understand and compare different social-ecological systems,  they are not sufficiently well defined to be considered formal hypotheses.  These propositions were developed in two workshops, in 2003 and 2004, in which participants compared the dynamics of 15 case studies in a wide range of regions around the world. The propositions raise many questions, and we present a list of...

A Hedonic Analysis of Cattle Prices in the Central Corridor of West Africa: Implications for Production and Marketing Decisions
Provedor de dados: 31
Autores: Williams,   Timothy O.; Okike,   Iheanacho; Spycher,   Ben.
Detailed weekly sales transactions data for the period January 2000-June 2001 from three frontier markets in the central corridor of West Africa were analyzed to identify the factors influencing short-run, intra-year cattle prices. The empirical results indicate that in addition to market location and seasonality of supply and sales, market participants show systemic preferences for specific cattle attributes (sex, weight, condition and finish) and are willing to pay premium prices consistent with their preferences. Communicating this information to producers can assist them to tailor their production and marketing decisions to meet market expectations and thereby improve their competitiveness, profitability and intra-regional livestock trade. Innovative...

The objectives of the study are to analyze household purchase of fresh tomatoes and to determine the magnitudes of the price premium paid for the organic tomatoes by estimating a hedonic price model. The study uses the 2003 ACNielsen Homescan panel data. The data set represents a nationally representative panel of U.S. households, which provide food purchase data for at-home consumption. For empirical implementation, parameters of the hedonic model were estimated using the Box-Cox transformation procedure. The results indicated that consumers value the...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop
Provedor de dados: 31
Autores: Edmeades,   Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

A importância do agronegócio familiar no Brasil
Provedor de dados: 123
Autores: Guilhoto,Joaquim J. M.; Silveira,Fernando G.; Ichihara,Silvio M.; Azzoni,Carlos R.
Este trabalho teve por objetivo avaliar o nível de atividade do agronegócio da agricultura familiar no Brasil, para o período de 1995 a 2003. Através dos Modelos de Insumo-Produto foi possível estimar a importância do Produto Interno Bruto do agronegócio familiar no contexto nacional. Concretamente, os resultados demonstram que cerca de 1/3 do agronegócio brasileiro advém da produção agropecuária realizada pelos agricultores familiares, cabendo observar, também, que o desempenho recente da agropecuária familiar e de todo o complexo a ela articulada vem sendo bastante positivo, superando, inclusive, as taxas de crescimento relativas ao segmento patronal.

A Lagrangian analysis of the Indian-Atlantic interocean exchange in a regional model - art. no. L14611
Provedor de dados: 5
Autores: Doglioli, Andrea; Veneziani, M; Blanke, Bruno; Speich, Sabrina; Griffa, A.
We present a new numerical Lagrangian technique based on the coupling of transport computation with spin analysis of trajectories. This method was applied to results from a high-resolution numerical model of the oceanic region around South Africa. We estimated an Indian-Atlantic leakage of about 14 Sv. In the western Cape Basin, approximately 30% of this transport is due to trapping eddies with a ratio between cyclones and anticyclones transport of 1.3. These findings are briefly discussed with respect to recent observations of the highly nonlinear regime found in this area of the Cape Basin.

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

Autores: Kasenge,   Valentine; Taylor,   Daniel B.; Bonabana-Wabbi,   Jackline.
In Uganda overall crop loss due to pests exceeds that caused by drought, soil infertility, or poor planting material. Integrated Pest Management (IPM) technologies can reduce pest damage to crops by emphasizing non-chemical control methods thereby reducing potential negative effects of chemicals on the environment while preserving profitability. This study investigates the adoption of eight IPM practices including intercropping, crop rotation, two improved varieties, incorporating an '‘exotic weed chaser'’, optimal planting dates, optimal planting density and fertilizer use. Variables include market forces, social factors, management factors, and technology delivery mechanisms. Results were consistent across the multivariate logit and ordered logit...

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

Autores: Huang,   Kuo S.
The matrices of food price elasticities and flexibilities derived from a complete food demand system approach are theoretical consistent and reciprocal with each other. The statistical estimates, however, show that by using the inverted elasticities to represent flexibilities or vice versa, cause sizable measurement errors. For agricultural policy and program analyses, directly estimated food price elasticities and flexibilities should be used.

This research determines the profitability for farmers of marketing film-wrapped Crown-Cut broccoli in Southwest Virginia. Historical price data was collected in three eastern terminal markets (Atlanta, Baltimore, and Philadelphia) for Crown-Cut and bunched broccoli from October 1998 to January 2005. Cost-of-production budgets were estimated for Crown-Cut broccoli. The economic data was entered into a market window analysis and the profitability of each market was evaluated. The profitability of Crown-Cut broccoli was illustrated by market-window graphics. Market windows were generated using an analysis platform developed by Kalo (1998). The profitability estimates were calculated by posting historical market prices by week in a Microsoft Excel spreadsheet...

A Mata Geweke–Hajivassiliou–Keane multivariate normal simulator
Provedor de dados: 31
Autores: Gates,   Richard.
An accurate and efficient numerical approximation of the multivariate normal (MVN) distribution function is necessary for obtaining maximum likelihood estimates for models involving the MVN distribution. Numerical integration through simulation (Monte Carlo) or number-theoretic (quasi–Monte Carlo) techniques is one way to accomplish this task. One popular simulation technique is the Geweke–Hajivassiliou–Keane MVN simulator. This paper reviews this technique and introduces a Mata function that implements it. It also computes analytical first-order derivatives of the simulated probability with respect to the variables and the variance–covariance parameters.

A mathematical model for growth in weight of silver catfish (Rhamdia quelen) (Heptapteridae, Siluriformes, Teleostei)
Provedor de dados: 65
Autores: Benaduce,Ana Paula da Silva; Rodrigues,Luiz Alberto Díaz; Mistro,Diomar Cristina; Baldisserotto,Bernardo.
The use of a mathematical model applied to biological science helps to predict the specific data. Based on biological data (weight and age) of silver catfish, Rhamdia quelen, a mathematical model was elaborated based on a nonlinear difference equation to demonstrate the relationship between age and growth in weight. Silver catfish growth was described following the Beverton-Holt model Pt+1 = (r Pt) / (1+ a Pt ), where r &gt; 0 is the maximum growth rate and a &gt; 0 is a constant of growth inhibition. The solution of this equation is Pt= 1 /{[1/P0 - a / (r-1)] 1/r t + a/ (r-1)}, were P0 is the initial weight of the fish. Through this model it was observed that the female reaches the theoretical maximum weight approximately at the age of 18 years and the...

A microeconomic model of discarding behaviour
Provedor de dados: 5
Autores: Macher, Claire; Guyader, Olivier; Boncoeur, Jean.
This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not explicitly take into account the sorting activity and mainly focus on quota and catch constraints. The discarding model described in the paper includes sorting as a factor explaining discards. The costs of sorting landings and the time to sort them are included in the approach. The model is developed for one species studied at a tow scale with the assumption that catches are exogenous. It is shown that taking sorting costs into account, discarding...

Bovine tuberculosis, caused by Mycobacterium bovis, is a disease of socio-economic and public health importance and of significance to international trade regulation. Allelic variants of several genes have been implicated in the genetic susceptibility to tuberculosis in some human populations, but little is known in cattle. We surveyed 34 European, 18 Asian, 20 Creole and 23 hybrid bovines for polymorphisms of the bovine solute carrier family 11 a1(Slc11a1) gene, formerly known as natural resistance associated macrophage protein (Nramp1), gene by typing the cattle using two microsatellite loci closely linked to this gene. The microsatellites used were 311-22, located at the 3' untranslated region (3' UTR) of the Slc11a1 gene, and ARO28 situated about 0.6...

Autores: Wesselingh, F.P.; Salo, J.A.
Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

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

A moderate melting model for the Voring margin (Norway) based on structural observations and a thermo-kinematical modelling: Implication for the meaning of the lower crustal bodies
Provedor de dados: 5
Autores: Gernigon, Laurent; Lucazeau, Francis; Brigaud, Frederic; Ringenbach, Jean-claude; Planke, Sverre; Le Gall, Bernard.
High P-wave velocities (7.1-7.8 km/s) lower crustal bodies (LCBs) imaged along volcanic margins are commonly interpreted as plume and break-up-related thick mafic underplating. This interpretation is partly challenged in this paper based on new seismic observations and modelling of the outer Voring Basin (Norway). An exceptional strong amplitude reflection, the T Reflection, is particularly well defined below the North Gjallar Ridge (NGR) between 7 and 8 s TWT. The T Reflection is located near the volcanic lava flows emplaced during the NE Atlantic breakup (similar to 55-54 Ma ago) and coincides with the top of the LCB, forming a mid-crustal dome. Based on structural and temporal relationships, we show that the dome clearly influences the structural...

A Modified Environmental Kuznets Curve for Sustainable Development Assessment Using Panel Data
Provedor de dados: 31
Autores: Costantini,   Valeria; Martini,   Chiara.
Sustainable development is a concept strictly connected with basic needs of the individuals. During the last years a number of empirical studies have tried to discover and quantify the causal relations between economic growth and environmental consumption and degradation. The most widely used empirical model is the so-called Environmental Kuznets Curve (EKC), nowadays applied to different polluting elements. Despite the huge diffusion of EKC studies, this model has been criticised for incompleteness of a sustainable development analysis. The aim of this paper is to build a Modified EKC (MEKC) in order to consider a wider concept of development rather than pure economic growth, including well-being aspects and sustainability of the development process....

A modified simple RFLP-PCR method for single nucleotide polymorphism (SNP) typing
Provedor de dados: 74
Autores: Xiao,Junhua; Xin,Xiujuan; Luan,Xiaohui; Dongzhi,Wei; Shengli,Yang.
We describe a modified single nucleotide polymorphism (SNP) typing method based on the restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR). This is a simple, economical method without the need for special equipment. For most SNP loci, a common restriction endonuclease (Hind III, EcoR I or BamH I) recognizing site (RER) can be introduced into one allelic form, but not the other by two rounds of mismatched PCR. The flanking regions can be changed by as many as five bases after PCR amplification with specially designed mismatching primers so the genotypes can be distinguished after digestion of the PCR products with corresponding endonucleases.

Autores: Brasili,   Cristina; Fanfani,   Roberto.
The Italian Industrial Districts (IDs) are now considered in the national and international literature as one of the main factors of the successful and rapid industrial development of Italy after the Second World War. In this paper we outline the general characteristics of the IDs approach and then the distinctive figures of the agrifood districts. A mosaic type of development characterised the geographical distribution of the different agrifood districts in the Italian experience. The different origins of agrifood districts often determines their production and structural characteristics of firms, with a relevant role of SMEs. In many cases, these districts originated from handcraft traditions and specific local demand. Their specialized production is...

The purpose of this paper is to evaluate the impact of the change on the Brazilian exchange rate policy implemented in January 1999, and to analyze agricultural sector transformations. Specifically, the paper is an attempt to identify the economic relations of the aggregate performance of the Brazilian commercial trade balance and total GDP or agricultural GDP, world income, and real exchange rate as of in the 1980-2006 (up to first quarter) period. The main conclusion of the study is that the exchange rate policy bands of Plano Real exerted a negative effect on exports and favored imports. With the liberation of the Brazilian exchange rate, from 1999 on, the estimated relations appear to have a positive net effect on the commercial trade balance of the...

Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

Autores: Fan,   Shenggen; Al-Riffai,   Perrihan; El-Said,   Moataz; Yu,   Bingxin; Kamaly,   Ahmed.
The overarching objective of this report is to use a multi-level analysis approach to assess the effects of various government spending on growth and poverty reduction and their trade-offs between these two goals and to offer future policy options to achieve the Millennium Development Goals (MDGs). The study involves analyses and simulations at the different levels: household, sector/region as well as macro levels. Different analytical tools are used at the different levels. Analyses at the different levels are initially executed independently, but final synergy is drawn through an integrated macro-micro framework. This new approach has enabled us to gain new knowledge as well as new policy insights. The study confirmed previous studies that universal...

A Need for Speed?  Rural Internet Connectivity and the No access / Dial-up / High-speed Decision
Provedor de dados: 31
Autores: Whitacre,   Brian E.; Mills,   Bradford F.
As residential high-speed Internet access has become more prevalent, the composition of the “"digital divide"” between rural and urban households has shifted.  In 2000, dial-up access rates in rural household lagged behind their urban counterparts by eleven percent.  By 2003, however, dial-up access rates were equal between rural and urban households, due in part to soaring high-speed rates in urban areas.  This paper explores the household decision between no Internet access, dial-up access, and high-speed access.  In particular, nested logit and multinomial logit specifications are compared.  The paper also uses a decomposition technique to estimate the contributions of various factors (including education, income, and infrastructure levels) to each of...

A new approach to chemical modification protocols of Aspergillus niger and sorption of lead ion by fungal species
Provedor de dados: 69
Autores: Rafiu Awofolu,Omotayo; Okechukwu Okonkwo,Jonathan; Roux-Van Der Merwe,Renate; Badenhorst,Jackie; Jordaan,Erika.
Biomasses of five fungi species (Aspergillus niger, Penicillium austurianum, Saccharomyces cerevisiae, Mucor arcindloides and Trichoderma reesi were evaluated for their uptake of lead ion from aqueous solution using batch systems. Both dead and live fungal biomasses were comparatively studied for their adsorption efficiencies. The effect of pH as one of the primary factors that influences sorption efficiency of metal ions in solution was also studied. Modification of the fungal biomass with the least sorption capacity was carried out using a four-step procedure. Three different modifying agents under the optimised experimental conditions were used. The percentage uptake of lead ion by fungi species ranged from: Aspergillus niger: 6.71-64.95% and...

A New Approach to Correct for Hypothetical Bias in Stated Preference Models
Provedor de dados: 31
Autores: Davies,   Stephen P.; Loomis,   John B.
Many times economists are asked to estimate the demand for new consumer goods or services for which no market data exists. Typically market researchers and economists answer this challenge using surveys that ask about intended purchases (Louviere, et al. 2000) or what has become known as stated preference (SP) data.  Tying this data to revealed preference (RP), or actual behavior, has been a target in a number of studies.  Simplistic calibrations have been investigated in past RP-SP studies, such as Loomis, et al. 2001. This paper offers an alternative solution that allows the magnitude of the calibration correction to vary based on Klein and Sherman's (1997) Orbit procedure.  This paper extends the original Orbit procedure of Klein and Sherman by...

A new concept for insect damage evaluation based on plant physiological variables
Provedor de dados: 42
Autores: Neves,Ademir D.; Oliveira,Ricardo F.; Parra,José R.P.
The objective of this study was to determine the damage levels caused by Orthezia praelonga Douglas, 1891 and Leucoptera coffeella (Guérin-Mèneville 1842), on rangpur lime and Obatã coffee leaves, respectively. Measurements were based on a new concept for the evaluation of the following plant physiological parameters: photosynthesis, stomatal conductance, leaf temperature and transpiration, and internal concentration of CO2 (by infrared analyzer). A negative correlation between infestation level and photosynthesis was found, where the negative inflexion point of the curve was considered as a reference for damage levels. The control level for O. praelonga is below the 7-13% limit for damaged leaf area (40 to 70 scales per leaf), while for L. coffeella it is...

A New Heterophyllous Spermacoce Species (Rubiaceae) from the Marungu Highlands, Democratic Republic of the Congo
Provedor de dados: 16
Autores: Dessein, S.; Robbrecht, E.; Smets, E.
Spermacoce heteromorpha Dessein (Rubiaceae, Spermacoceae) is newly described and illustrated. It grows on the Marungu highlands of the Democratic Republic of the Congo (D.R. Congo) at altitudes of 1800 to 1900 m. The species resembles the Tanzanian Spermacoce taylorii Verdcourt, from which it mainly differs in having terminal inflorescences, only slightly exserted anthers, and densely pubescent stems. Moreover, Spermacoce heteromorpha features marked heterophylly, with long leaves at the plant’s base and much shorter cauline leaves, a type of heterophylly rarely observed in Spermacoce or in the Rubiaceae as a whole. The finding of this species exemplifies the unique floristic richness of this underexplored part of D.R. Congo.

A new species of Andracantha Schmidt (Acanthocephala, Polymorphidae) parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin) (Aves, Phalacrocoracidae) from southern Brazil
Provedor de dados: 104
Autores: Monteiro,Cassandra M.; Amato,José F. R.; Amato,Suzana B.
A new species of the genus Andracantha Schmidt, 1975, parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin, 1789), is described and compared to the other six species currently placed in the genus. The new species differs from the previously known species of Andracantha by having two inflations in the anterior region of the trunk and by having the testes in tandem in the central region of the body. These differences were also responsible for the diagnosis emendation of the genus now proposed. The orange pigmentation of the acanthocephalans recently collected from the intestine is documented for the first time in a species of this genus. This is the first record of adult specimens of any species of Andracantha in South America.

A New U.S. Farm Household Typology: Implications for Agricultural Subsidies
Provedor de dados: 31
Autores: Briggeman,   Brian C.
Changes in American agriculture have yielded a diversity of farm types. These changes have extended beyond the farm business and into the farm household. The objective of this research is to motivate, develop, and discuss the policy implications of a new typology of U.S. farm households that is based on household economic theory. Using the 2003 Agricultural Resource Management Survey and statistical analysis, six mutually exclusive groups of U.S. farm households are identified as the U.S. Farm Household Typology. This typology is then compared to the current Economic Research Service Farm Typology and used to investigate the distribution of government payments.

Deafness is a complex disorder affecting 1/1000 infants. In developed countries, more than 50% of deafness cases are thought to have a genetic cause. At least 40 loci for dominant non-syndromic deafness and another 30 for recessive non-syndromic deafness have been described. Mutations in the GJB2 gene are the cause of an important number of cases of non-syndromic recessive deafness but are not as common in non-syndromic dominant deafness cases. We describe here a new dominant mutation (G21R) in the GJB2 gene which causes deafness and has been identified in a three generation Cuban family with dominant non-syndromic congenital sensorineural profound deafness.

A novel nonsense mutation, E150X, in the SOX9 gene underlying campomelic dysplasia
Provedor de dados: 74
Autores: Shotelersuk,Vorasuk; Jaruratanasirikul,Somchit; Sinthuwiwat,Thivaratana; Janjindamai,Waricha.
Campomelic dysplasia (CD) is an autosomal dominant skeletal malformation syndrome with features including bowed lower limbs with pretibial skin dimpling, hypoplastic scapulae and pelvic bones, and 11 pairs of ribs. Mutations in the SOX9 gene have been identified to cause CD. The gene encodes a transcription factor containing a dimerization, a high mobility group, and a C-terminal transactivation (TA) domain. Up to now, 35 SOX9 mutations have been published. In the present study, we describe a Thai girl with clinically and radiologically typical CD. Direct sequencing analysis of the PCR products for the entire coding region of SOX9 revealed that she was heterozygous for a novel 448G &gt; T in exon 2 of SOX9. The DNA change was expected to result in E150X...

A Panel Data Study of the Determinants of Micronutrient Intake in China
Provedor de dados: 31
Autores: Liu,   Yi; Shankar,   Bhavani.
Rapid economic growth in China has resulted in substantially improved household incomes. Diets have also changed, with a movement away from traditional foods and towards animal products and processed foods. Yet micronutrient deficiencies, particularly for calcium and vitamin A, are still widespread in China. In this research we model the determinants of the intakes of these two micronutrients using household panel data, asking particularly whether continuing income increases are likely to cause the deficiencies to be overcome. Nonparametric kernel regressions and random effects panel regression models are employed. The results show a statistically significant but relatively small positive income effect on both nutrient intakes. The local availability of...

A Panel Unit Root and Panel Cointegration Test of the Complementarity Hypothesis in the Mexican Case, 1960-2001
Provedor de dados: 31
Autores: Ramirez,   Miguel D.
Using panel data, this paper tests whether public and private capital have a positive and significant effect on aggregate output and labor productivity for Mexico during the 1960-2001 period.  The richer information set made possible by the sectorial data enables this study to utilize the methodologically sound “group-mean” Fully Modified Ordinary Least Squares (FMOLS) procedure developed by Pedroni  to generate consistent estimates of the relevant panel variables in the cointegrated production (labor productivity) function. The results suggest that, in the long run, changes in the stocks of  public and private capital and the economically active population (EAP) have a positive and economically significant effect on output ( and labor productivity).

Autores: Clarke, Dr Sarah M.; Hinchsliffe, Miss Kay E.; Haigh, Miss Zoe; Jones, Dr Hannah; Pearce, Dr Bruce; Wolfe, Prof Martin S; Thomas, Dr Jane.
A participatory research methodology was used to compare the performance of UK wheat varieties under organic conditions. Plots of three breadmaking winter wheat varieties (Hereward, Solstice and Xi19) and a mixture (1:1:1) of the varieties were grown at 19 UK farms in two seasons (2003/04 and 2004/05). Meas-urements were taken of growth habit, yield and grain quality. Grain yields in both seasons showed significant site by variety interactions, although the variation among sites was greater than among varieties in both instances. Wheat grown at Western sites was significantly shorter and higher-yielding than that grown at Eastern sites in 2003/04 but significantly taller in 2004/05. As with grain yield, greater variation among site than variety was found...

Farmer participation was essential in developing a uniquely useful set of wheat variety trials data on a wide range of organic farms over two years. Although the trials were successful, it became clear that some of the participating farmers felt there were some limitations in the process. These included a lack of ownership in the project and a concern for more researcher help. It was clear that a greater time in-vestment was needed at the start of the project to help with farmer understanding and ownership. De-spite the negative comments, farmers appreciated their involvement, particularly in contrasting their own views and information with that from the wider scene.  Farmer participation is essential for systems-level research and this project helped to...

Zebra mussel (Dreissena polymorpha) is an invasive species that has proliferated in European and North American rivers and lakes during the last century. In this study, D. polymorpha has been used to provide information on contamination levels and biological effects in the Seine Estuary (France). The bivalves accumulated polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) to a high degree with values reaching 800 ng/g dry weight for PCBs (sum of 20 congeners), and 1,000 ng/g dry weight of PAHs (sum of 14 compounds) in the whole body. These values are among the highest reported of PCBs and, to a lesser extent, of PAHs in other contaminated areas in the world. Toxic equivalent quantities of PCBs and PAHs detected in zebra mussels...

A portable bio-amplifier for electric fish research: design and construction
Provedor de dados: 83
Autores: Wells,Jonathan K.; Crampton,William G. R.
The weak electric organ discharges (EODs) of gymnotiform knife fishes can be readily amplified with a wideband amplifier connected to submerged electrodes. The output from such an amplifier can then be monitored with audio speakers or digitized for subsequent analysis. Commercially available devices are expensive and usually require mains electrical power. Here we provide design notes and instructions for the construction and calibration of a cheap, portable, battery-powered, AC-coupled wideband bio-amplifier. This device was designed to allow electric fishes to be located in the field, and also to permit the relatively noise-free acquisition of EOD waveforms from specimens held in temporary captivity. This contribution is intended to encourage students of...

The challenge confronting those seeking to understand the institutional dimensions of global environmental change and patterns of land-use and land-cover change is to find effective methods for analyzing the dynamics of socio-ecological systems. Such systems exhibit a number of characteristics that pose problems for the most commonly used statistical techniques and may require additional and innovative analytic tools. This article explores options available to researchers working in this field and recommends a strategy for achieving scientific progress. Statistical procedures developed in other fields of study are often helpful in addressing challenges arising in research into global change. Accordingly, we start with an assessment of some of the enhanced...

Ultrasonography (US) has been applied to the ovary and the uterus of domestic animals from the late 1980s, and established in 1990s as a practical tool for animal production. US made it possible to detect pregnancy at a very early stage and, most importantly, to observe the real-time dynamics of follicular development and hence the discovery of follicular waves. This has greatly contributed to our understanding of ovarian physiology and helped us to develop several "pin-point" protocols for hormonal treatment. While US may not seem to fit preconceived ideas of a "green" technology, it does not contravene environmental priorities, and it is non-invasive ("ethical") and non-hormonal ("clean"). Using the US technology that is now commercially available at a...

A preliminary genetic linkage map for the European flat oyster Ostrea eduli
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Halley, Chris; Boudry, Pierre; Beaumont, Andy.
The European flat oyster, Ostrea edulis, occurs naturally from Norway to Morocco in the North-Eastern Atlantic and throughout the Mediterranean. The oyster has been a harvested species for at least 6000 years. However, it successively suffered from over harvesting and then from two protozoan diseases during the 1960s and its production has drastically decreased in Europe from that time. Following two generations of selection for tolerance to one of these diseases (bonamiosis), our aim is to optimize this selection with the assistance of molecular markers, that is to say to implement marker-assisted selection. This will enhance the efficiency of selection by reducing the generation time, as the selection on sites cannot be made before the oysters are...

Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Harley, Crhis; Boudry, Pierre; Heurtebise, Serge; Beaumont, Andy.
The flat oyster Ostrea edulis is the species endemic to European coasts, both Atlantic and Mediterranean. It has been exploited since Roman times, but its aquaculture production decreased from around 20000 tons in the 1950's to 1500 tons today because of two successive diseases due to the intracellular parasites Marteilia refringens and Bonamia ostreae. Since 1985, Ifremer has been undertaking a breeding program to produce families of oysters tolerant to Bonamia. In this context, a further step would be to identify QTLs for resistance to this parasite. Therefore, as a first step a genetic map is now being built. The establishment of a genetic linkage map will provide a foundation for the mapping of QTLs, with the ultimate objective to implement...

We used Markov chains to assess residence time, first passage time, rare of transfers between compartments, recycling index with a general mathematical formalism. Such a description applies to any flow-balanced system that can be modelled as a series of discrete stages or compartments through which matter flows. We derived a general set of equations from a probabilistic approach and applied them to a food web and a physical system derived from the literature. We therefore analysed preferential pathways of matter and behaviour of these systems and showed how it was possible to build up and exploit indices on the basis of a transition probability matrix describing the network, and to characterize with a generic algorithm: (1) the total indirect relationships...

Autores: Eigenraam,   Mark; Doering,   Otto C., III; Spinelli,   Felix.
Increasing recognition of the environmental impact of agriculture has led to increasing public activity around the world encouraging public conservation programs. Different countries have taken different program approaches to accomplish this. The comparison and contrast here is between Australia and the United States, examining the CREP program in the U.S. and the Eco Tender program in Australia. A different historical experience in the U.S. sets certain parameters that are expected in their conservation programs. To some extent, the Australian program could take more of a clean slate approach. The Australian program is able to take a broader landscape approach, specifically considering multiple benefits with knowledge about off-site benefits as well. This...

A production function analysis of commercial dairy farms in the Highlands of Eritrea using ridge regression
Provedor de dados: 31
Autores: Ghebremariam,   W.K.; Ortmann,   Gerald F.; Nsahlai,   I.V.
This study presents a production function analysis of fresh milk production in the Highlands of Eritrea, where most dairy farmers in Eritrea are located. To ensure representative production functions, this region was divided into three relatively homogenous study areas, namely Central Zone, Mendefera and Dekemhare. Most data for the study were collected in a survey of 120 respondents using a structured questionnaire. To obviate the problem of multicollinearity among explainatory variables, ridge regression was used to estimate milk production functions for each study area.

A proposal of a standardised nomenclature for terminal minute sister chromatid exchanges
Provedor de dados: 74
Autores: Drets,Máximo E.; Santiñaque,Federico F.; Obe,Günter.
We described spontaneous minute sister chromatid exchanges (SCE) in telomeric regions of human and Chinese hamster ovary (CHO) chromosomes more than 10 years ago. These structures, which we called t-SCE, were detected by means of highly precise quantitative microphotometrical scanning and computer graphic image analysis. Recently, several authors using the CO-FISH method also found small SCEs in telomeric regions and called them T-SCE. The use of different terms for designating the same phenomenon should be avoided. We propose ter SCE as a uniform nomenclature for minute telomeric SCEs.

A new demand system, the QGAITL model, nesting the quadratic almost ideal, translog and LES models as its special cases, is introduced and estimated in this paper. Employing urban household data of four major food items from Jiangsu China in 2001, empirical evidence from both in-sample evaluations and out-of-sample forecasting comparisons shows that the QGAITL is superior to its nested models, whether or not demographic effects are incorporated.

This series of six reports entitled: "On-Farm Food Safety and Environmental Farm Plans: Identifying and Classifying Benefits and Costs" was initiated soon after the launch of the Agricultural Policy Framework (APF) in 2002. The APF recognized the importance of food safety and environmental concerns for the future growth of the agriculture and Agri-food sector. For this reason, Agriculture and Agri-Food Canada (AAFC) commissioned this series of reports to develop a conceptual framework to strengthen our understanding of the potential benefit and cost implications of On-farm Food Safety (OFFS) and Environmental Farm Plans (EFP) that were key components of the APF. The reports were prepared by a group of academics with extensive knowledge of the agriculture...

A quantitative analysis of Zimbabwe's land reform policy: An application of Zimbabwe SAM multipliers
Provedor de dados: 31
Autores: Juana,   James S.
This study was designed to quantitatively investigate the economy-wide impact of land reform policies in Zimbabwe. Land reforms came with the realm of independence in Zimbabwe. Four models were used to implement the reform policies. The paper uses the updated 1991 Social Accounting Matrix for Zimbabwe and the Central Statistics Office's household data on resettled families in Zimbabwe. The paper computes the sectoral SAM multipliers and then uses household data on resettled families to simulate the impact of specific land reform models on the economy. The simulated results show that land reform, if well planned and systematically and carefully implemented, could generate economy-wide benefits for Zimbabwe and could lead to income redistribution in favour...

A randomized, double-blind, and placebo-controlled study with tranexamic acid of bleeding and fibrinolytic activity after primary coronary artery bypass grafting
Provedor de dados: 56
Autores: Santos,A.T.L.; Kalil,R.A.K.; Bauemann,C.; Pereira,J.B.; Nesralla,I.A.
Cardiopulmonary bypass is frequently associated with excessive blood loss. Platelet dysfunction is the main cause of non-surgical bleeding after open-heart surgery. We randomized 65 patients in a double-blind fashion to receive tranexamic acid or placebo in order to determine whether antifibrinolytic therapy reduces chest tube drainage. The tranexamic acid group received an intravenous loading dose of 10 mg/kg, before the skin incision, followed by a continuous infusion of 1 mg kg-1 h-1 for 5 h. The placebo group received a bolus of normal saline solution and continuous infusion of normal saline for 5 h. Postoperative bleeding and fibrinolytic activity were assessed. Hematologic data, convulsive seizures, allogeneic transfusion, occurrence of myocardial...

Autores: Anu,Vinod Ranade; Rajalakshmi,Rai; Latha,Venkatraya Prabhu; Mangala,Kumaran.
An unusual presentation of the duplication of thoracic duct with a rare lymphatico- venous communication was found during the routine dissection for undergraduate students. The thoracic duct duplicated at the level of T12 vertebra. Normally thoracic duct opens into the junction of left internal jugular vein and subclavian vein. On the right side of the neck, the right lymphatic duct conveys the lymph from the head and neck, the upper extremity and the right side of the thorax to the right innominate vein. Here, the duplicated thoracic duct on the left side opened directly into the inferior vena cava. The above case is discussed with regard to its development, incidence, and clinical significance

A Reappraisal of the Role of Agriculture in Economic Growth in Melanesian Countries
Provedor de dados: 31
Autores: Fleming,   Euan M.; Fleming,   Pauline.
Fortunes in the agricultural sectors of four of the largest South Pacific countries are traced in recent decades by estimating the single factoral terms of trade index. The single factoral terms of trade are measured for agriculture in four Melanesian countries-Fiji, Papua New Guinea, Solomon Islands and Vanuatu-over the period, 1970 to 2002. This index provides a useful method to assess changes in returns to factors employed in agricultural production in these countries. Except in Solomon Islands, farmers experienced a deteriorating index, indicating that they have reaped progressively lower returns to their resources. In Solomon Islands, returns to resources are shown to have increased slightly. A sustained contribution by the agricultural sector to...

A recombination point is conserved in the mitochondrial genome of higher plant species and located downstream from the cox2 pseudogene in Solanum tuberosum L.
Provedor de dados: 74
Autores: Tada,Susely F.S.; Souza,Anete P.
The potato (Solanum tuberosum L.) mitochondrial cox3/sdh4/pseudo-cox2 gene cluster has previously been identified by heterologous hybridization using a Marchantia polymorpha sdh4 probe. In our present study we used Southern blotting using sdh4 and cox2 probes to show that the sdh4 and cox2 genes are clustered in the mitochondria of potato, soybean and pea. Northern blotting revealed cotranscription of sdh4 and cox2 in potato but not in cauliflower, indicating that these genes are not clustered in cauliflower. A putative recombination point was detected downstream of the cox2 pseudogene (pseudo-cox2) in potato mitochondrial DNA (mtDNA). This sequence corresponds to a 32 bp sequence which appears to be well-conserved and is adjacent to the terminals of some...

A re-evaluation of evidence raises questions about the fasting migration hypothesis for Swainson's Hawk (Buteo swainsoni)
Provedor de dados: 68
Autores: Bechard,Marc J.; Sarasola,Jose H.; Woodbridge,Brian.
We examined the fasting migration hypothesis for Swainson's Hawks (Buteo swainsoni) by estimating the length, duration, and speed of the migration between North and South America and measuring changes in their body masses at various times throughout the year. We instrumented 34 adult Swainson's Hawks with satellite radios on their breeding grounds in western North America to determine the duration, length, and speed of the migration. Migrating south at 188 km/day, it took Swainson's Hawks 51 days to complete their 13504 km migration to their austral summer grounds. Averaging only 150 km/day on their return migration, it took them 60 days to complete the shorter 11952 km migration back to North America. Adult male and female Swainson's Hawks had average...

A Reluctance to Assimilate
Provedor de dados: 31
Autores: Stark,   Oded; Fan,   C. Simon.
Quite often, migrants appear to exert little effort to absorb the mainstream culture and to learn the language of their host society, even though the economic returns (increased productivity and enhanced earnings) to assimilation are high. We show that when interpersonal comparisons affect individuals' wellbeing and when a more intensive assimilation results in migrants' comparing themselves more with the richer natives and less with fellow migrants, then the effort extended to assimilate will be muted.

Autores: Zuanon,Jansen; Bockmann,Flávio A.; Sazima,Ivan.
We studied a specialised assemblage of sand-dwelling fish species from a streamlet in central Amazonia. The five sanddwelling species comprised 15.2 % of the total number in the streamlet (33 species). Two of the sand-dwellers are daytime foragers, Characidium cf. pteroides (Crenuchidae) and Stauroglanis gouldingi (Trichomycteridae), whereas three ones are night-time foragers, Gymnorhamphichthys rondoni (Rhamphichthyidae), "Imparfinis" pristos and Mastiglanis asopos (Heptapteridae). With the exception of C. cf. pteroides, the remainder species bury in the sand during their resting period. All five species bear a cryptic, sand-colour pattern, and some are translucent, traits which we regard as advantageous both for evasion from predators and for approaching...

A review of the chemistries of redox sensitive elements within suboxic zones of oxygen minimun regions
Provedor de dados: 72
Autores: Kenneth W,Bruland.
This presentation is a review of the chemistries of redox sensitive elements within suboxic regions of extreme oxygen minimum zones. Suboxic regions are defined as extreme oxygen minimum zones with dissolved oxygen &lt; 10 µmol kg-1 (and likely &lt;5 µmol kg-1), and with clear evidence of nitrate reduction, but not sulfate reduction. These are regions with nitrate deficits &gt; 10 µmol kg-1 or N* values of _10 µmol kg-1. Suboxic regions predictably occur in the tropical and subtropical eastern Pacific and the Arabian Sea. These suboxic zones are important in the global biogeochemistry of nitrogen and act as an important sink for fixed nitrogen. Minor and trace element redox couples such as iodate/iodide and leachable particulate Mn/dissolved Mn undergo...

A satellite altimeter model for ocean slick detection - art. no. C04004
Provedor de dados: 5
Autores: Tournadre, Jean; Chapron, Bertrand; Reul, Nicolas; Vandemark, D.
[1] About 5% of Ku-band altimeter ocean data are degraded by the occurrence of high radar return cross sections (sigma(0)), usually called sigma(0) blooms. During blooms, which occur during no or low wind conditions, the mean altimeter waveform can significantly depart from the expected shape. In about 60% of the cases the waveforms are distorted to such an extent that either the range tracker loses lock or the off-nadir angle estimate becomes unrealistic. The analysis of high data rate altimeter waveforms during bloom events reveals the presence of V-shaped patterns similar to the ones observed during rain events. These patterns trace small-scale (i.e., smaller than the altimeter footprint) changes in surface backscatter. Such variations of surface...

Autores: Quadros,V.L.; Mayer,S.V.; Vogel,F.S.F.; Weiblen,R.; Brum,M.C.S.; Arenhart,S.; Flores,E.F.
Calves born persistently infected with non-cytopathic bovine viral diarrhea virus (ncpBVDV) frequently develop a fatal gastroenteric illness called mucosal disease. Both the original virus (ncpBVDV) and an antigenically identical but cytopathic virus (cpBVDV) can be isolated from animals affected by mucosal disease. Cytopathic BVDVs originate from their ncp counterparts by diverse genetic mechanisms, all leading to the expression of the non-structural polypeptide NS3 as a discrete protein. In contrast, ncpBVDVs express only the large precursor polypeptide, NS2-3, which contains the NS3 sequence within its carboxy-terminal half. We report here the investigation of the mechanism leading to NS3 expression in 41 cpBVDV isolates. An RT-PCR strategy was employed...

In the light of lessons learned from recent disasters (The London Subway Bombings, and Hurricane Katrina), it has become clear that government and private organizations need to be prepared to communicate effectively with consumers before, during and after a disaster in order to minimize harm to consumers and to the nation.  Findings from a national survey of attitudes of U.S. Residents about terrorism provides information for the development of such communications.  Using "Predictive Segmentation" this study demonstrates that consumers can be grouped based on their general attitudes and values in such a way that their diversity can be captured in a simple framework of six segments reflecting striking differences with respect to their level of concern over...

In this paper the results of a situation analysis of the Australian venison industry are presented from a study commissioned as part of the development process of an endorsed strategic plan for the Australian farmed venison industry. An extensive literature review, combined with in depth interviews with industry participants, revealed that the Australian venison industry is currently in an extended slump, characterised by a lack of viability within the industry. This lack of viability is due to many factors including, a decline in the number of large scale producers, reduced slaughter and production levels, historically low farm gate returns and very low demand for venison in the domestic market. A significant decline in export demand for venison has also...

A soft technology to improve survival and reproductive performance of Litopenaeus stylirostris by counterbalancing physiological disturbances associated with handling stress
Provedor de dados: 5
Autores: Wabete, Nelly; Chim, Liet; Pham, Dominique; Lemaire, Pierrette; Massabuau, J.
The consequences of handling stress (fishing, transfer, eyestalk ablation) on shrimp broodstock are poorly documented. The weakness of farmed shrimp, Litopenaeus stylirostris, during winter is a major problem in New Caledonia, because of seasonal climate (tropical-sub-temperate). The transfer of broodstock in winter from earthen outdoor ponds to indoor maturation tanks in the hatchery (T=20 degrees C, Salinity=35 parts per thousand, fed shrimp) usually leads, after 48 h, to high mortality (up to 70%). Eyestalk ablation to induce ovarian maturation in females leads to further mortality.   Starting from a background analysis of physiological disturbances (initial osmoregulatory imbalance) associated with handling stress (Wabete, N., Chim, L., Lernaire, P.,...

A Spatial Model of Dolphin Avoidance in the Eastern Tropical Pacific Ocean
Provedor de dados: 31
Autores: Hicks,   Robert L.; Schnier,   Kurt E.
This paper examines the impact of dolphin-safe eco-labeling and how it fundamentally altered the spatial distribution of fishing effort and fishermen's willingness to pay to avoid dolphins.  To do this, a dynamic discrete choice econometric model is applied to the Eastern Tropical Pacific tuna fishery. This econometric approach combines a dynamic programming component with the static discrete site choice model.  This estimator couples the current period projected profits associated with fishing a specific site with the value of all future location choices on the cruise, assuming choices are made optimally.  The key feature of this model is that it recovers behavioral parameters and solves the dynamic programming problem recursively.  The dynamic site...

A Spatial Simultaneous Growth Equilibrium Modeling of Agricultural Land Development in the Northeast United States
Provedor de dados: 31
Autores: Hailu,   Yohannes G.; Brown,   Cheryl.
This study aims to understand the relationship between regional growth in population, employment, and per capita income, and agricultural land values and development in the Northeast United States. A system of spatial simultaneous equations is estimated using three-stage-least squares on county level data. Results indicate that regional growth positively influences agricultural land values and negatively affects the stock of agricultural lands. Farm performance and some farmland protection policies were not effective in preserving farmland. The study recommends that agricultural land protection policies could be better coordinated at a regional level and more effective if integrated within state economic development programs.

A standard weight equation to assess the body condition of pejerrey Odontesthes bonariensis
Provedor de dados: 47
Autores: Colautti,Darío C.; Remes Lenicov,Mauricio; Berasain,Gustavo E.
We developed a standard weight equation Ws to aid in the analysis of pejerrey Odonthestes bonariensis body condition over time and across populations using the relative weight index Wr. Weight - length data were compiled from 73 populations of pejerrey (N=16.022) from the Argentine pampas region. We used the regression-line-percentile technique, which provides a 75th-percentile standard by length intervals of 10 mm, to develop the Ws equation. The proposed equation is log10 Ws=-5,267+3,163 log10 Lst; Ws is weight in grams and Lst is standard length in millimeters. This equation is proposed for use with pejerrey between 120 and 520 mm of Lst. Values for Wr calculated with the Ws equation did not consistently increase or decrease as function of fish length,...

A standardized protocol for genomic DNA isolation from Terminalia arjuna for genetic diversity analysis
Provedor de dados: 69
Autores: Sarwat,Maryam; Singh Negi,Madan; Lakshmikumaran,Malathi; Kumar Tyagi,Akhilesh; Das,Sandip; Shankar Srivastava,Prem.
For studying genetic diversity in natural populations of Terminalia, a medicinal plant, our attempts to isolate high quality DNA using several previously reported protocols and even modifications were unsuccessful. We therefore combined CTAB based isolation, and column based purification step, to isolate DNA from Terminalia arjuna. The DNA isolated using this standardized protocol was high in quality and suitable for restriction digestion and generation of random amplification of polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP).

A statistical basis for selecting parameters for the evaluation of soil penetration resistance
Provedor de dados: 63
Autores: Leão,Tairone Paiva; Silva,Álvaro Pires da.
Measurements of soil penetration resistance (SR) have been frequently used for the evaluation of soil structural quality for plant growth. However, different data analysis approaches have been used, without a previous evaluation of their statistical quality. In this study we tested the hypothesis that the mean is the parameter with best statistical properties to evaluate alterations in soil penetration resistance in response to soil use and management, as compared to other SR statistical parameters. Undisturbed (5 × 5 cm) soil cores were collected from three sampling sites with different degrees of compaction: an undisturbed site under native scierophylous forest (NC); a site under short-duration grazing with post-grazing residue maintained at 2.0 to 2.5...

A Stochastic Frontier Approach for Measuring Technical Efficiencies of Date Farms in Southern Tunisia
Provedor de dados: 31
Autores: Belloumi,   Mounir; Matoussi,   Mohamed Salah.
The main objective of this research is to compare estimates of technical efficiency obtained from the stochastic frontier approach for two samples of farmers of private and water user associations in the Nefzaoua Oases region (Tunisia), which are characterized by a severe scarcity of water and especially a high degree of salinity. Technical inefficiency effects are modeled as a function of farm-specific socioeconomic factors. Results suggest that both systems are technically inefficient. On average, the private system is found to be slightly more efficient than the associative one. Date yield could be explained mainly by four variables: water quantity applied per palm tree, labor per palm tree, phosphate per palm tree, and water salinity. Output...

A Strategic Perspective on the Impact of Food Safety Standards on Developing Countries
Provedor de dados: 31
Autores: Henson,   Spencer J.; Jaffee,   Steven.
This paper explores the competing concepts of 'standards as barriers' and standards as catalysts' in the context of food safety standards in international trade in agricultural and food products.  It is suggested that food safety standards can act as both a barrier to trade and the basis of competitive positioning for developing countries in international markets.  This suggests that the application of a strategic framework to analyze and assess alternative responses to evolving food safety standards can throw some light on the circumstances under which standards act to prohibit trade or, alternatively, create competitive trade opportunities.  The use of such a framework is illustrated through a brief case study of fish and fishery product exports from...

A Structural Econometric Model of Consumer Demand at Pick-Your-Own Fruit Operations
Provedor de dados: 31
Autores: Carpio,   Carlos E.; Wohlgenant,   Michael K.
This paper develops a fully structural econometric consumer demand model for goods which have time and monetary costs, and where time spent obtaining the goods also enters into the utility function. The model is used to analyze customers'’ decision to buy pick-your-own versus pre-harvested fruit at North Carolina pick-your-own fruit operations.  The empirical application distinguishes the double effect of time as a resource constraint and also providing utility. Elasticity estimates show that strawberries sold at pick-your-own operations are price elastic, with pick-your-own fruit being less price elastic than pre-harvested fruit.

Autores: Cognard, Jean Yves; Davies, Peter; Sohier, S; Creac' Hcadec, R.
The objective of this study is to define a reliable tool for dimensioning of adhesively bonded assemblies, particularly for marine and underwater applications. This paper presents experimental and numerical results, which describe the non-linear behaviour of an adhesive in a bonded assembly for various loadings. A modified Arcan fixture, well-suited for the study of the behaviour of bonded metal-metal assemblies, was developed in order to focus on the analysis of the behaviour of the adhesive in thin films. The edge effects are minimised by using an appropriate design of the substrates so that experimental results give reliable data. To analyze the kinematics of the deformation of the adhesive joint non-contact extensometry techniques were employed. Thus,...

In Taiwan, the traceability system (TS) of whole food chain is in infantile time. Yin Chuan Organic Farm, constituted by the team of rice production and marketing (TRPM), is the first brand in Taiwan rice market. The leader of TRPM is not only to produce the premising rice quality, but also to implement the (TS) that was introduced by Taiwan government with a great result and could be a successful experience passed to other proprietors. The findings of this paper are listed as following: 1. The TS executed by the case is only emphasized on the production side that needs to build more detailed marketing side. 2. The key successful factor to get sound TS model is to have obvious purposes and system harmony.

The purpose of this survey is to review the available empirical evidence on the impacts of agricultural trade liberalization on poverty – considering both the impact of domestic and international liberalization. Since trade liberalization is generally an economywide phenomenon, with tariff cuts occurring across a wide range of commodities, we do not restrict ourselves to episodes where only agricultural trade was liberalized, although emphasis in this survey is given to agricultural trade policies. Furthermore, given the difficulty of isolating the effects of trade policies alone, we will also consider the impact of other types of external shocks which have the effect of changing the relative prices of tradeable and non-tradeable goods.

A Synthesis of Theoretical Concepts for Analysing Non-Farm Rural Employment
Provedor de dados: 31
Autores: Buchenrieder,   Gertrud; Mollers,   Judith.
Employment diversification is a major livelihood strategy in rural areas and is thus a focal point of the ongoing rural development debate. The issue of non-farm diversification is undoubtedly complex and its determinants are difficult to identify. Increasingly, there is a need to address, clarify and bring together theoretical concepts for analysing non-farm rural employment (NFRE). With this in mind, the objective of this paper is to summarize and link existing theories and to introduce some new aspects with regard to modelling NFRE and employment diversification. NFRE dynamics are closely interrelated with the institutional framework and its incentives and constraints. The behaviour of rural decision-makers also depends on fundamental determinants such...

A Term Structure Model for Commodity Prices: Does Storability Matter?
Provedor de dados: 31
Autores: Lin,   Chuanyi; Roberts,   Matthew C.
Econometric models of commodity prices have been estimated for more than 80 years, but both structural and time series models require ad hoc assumptions to capture all the features of commodity price series. Commodities can be broadly divided into two categories: storable and non-storable. The purpose of this study is to investigate the effects of storability on commodity futures pricing, especially whether meats can be reasonably approximated by storable commodity term structure models. From the empirical analysis of seven commodity futures prices, the two-factor Schwartz model is found to perform well for less storable commodities.

A territorial approach to organic farming: the case of eco-regions in Austria
Provedor de dados: 21
Autores: Schermer, Markus.
The ongoing changes from an agricultural to a rural society require from farmers to define their position new. Organic agriculture provides a value system which is well accepted by non-agricultural rural stakeholders and can therefore be a potential starting point for territorial sustainable development. In Aus-tria the approach of eco-regions (Bioregioen) provides such an approach. The paper gives some preliminary results on the preconditions necessary for the establishment of such an approach building on the results of an ongoing national project. Furthermore different strategies how to position the organic agenda within the framework of various regional development strategies are discussed.

This paper developed an economic framework to analyze the economic impacts of an ECP on trade flows within the context of a partial equilibrium approach which assumes that non-payment risks are distinct between selling at home and abroad based on difficulties and expense in recovering non-payments are different in the two markets.  A two-country partial equilibrium trade model is developed to analyze the economic impact of the export credit insurance and/or guarantees on trade flows.  The results also show that to minimize or recover the efficiency loss, an export credit program can be employed to increase the exported quantity and reduce the excessively high equilibrium price as a result of non-payment risk.

A Theoretically-Consistent Empirical Non-Expected Utility Model of Ambiguity: Nuclear Waste Mortality Risk and Yucca Mountain
Provedor de dados: 31
Autores: Riddel,   Mary C.; Shaw,   W. Douglass.
Risk aversion is well established in the health and safety literature, and ambiguity is addressed in theoretical and experimental economics literature, but few theoretically-consistent empirical models addressing the relationship between ambiguity, risk, and preferences exist. Even fewer address ambiguity about health or mortality risks.  To fill this gap, we propose a theoretical non-expected-utility model (NEUM) that is relatively easy to estimate.  The NEUM we develop hinges upon two sources of variability, one over risk and the other over uncertainty about the risk. The model, like the second-order probability models of Segal (1987) and Quiggin (1982), grounds ambiguity in the compound lottery context. However, our model differs from previous...

Thirtle et al (2003) have provided a Total Factor Productivity (TFP) index for UK agriculture. This note follows a similar methodology to construct a TFP index for Scottish agriculture beginning in 1973 and ending in 2004. Essentially, Scottish agricultural growth grew strongly during the 1970s but then fell to negative levels over the period 1984-2004. In comparison to the UK Index, Scotland has performed poorly and is only showing signs of a positive recovery from 2000 onwards.

A Total Social Factor Productivity Index for the UK Food Chain Post-Farm Gate
Provedor de dados: 31
Autores: Barnes,   Andrew Peter; McVittie,   Alistair.
The UK post-farm gate food chain comprises manufacturing, wholesaling , retailing and catering. Current turnover is around £250 billion per annum. Total factor productivity measures the ratio of inputs to outputs. However, most studies have only included the marketable inputs and outputs within the system. Following criticisms of the negative effects of the food chain this paper adopts a n index based approach to measuring Total Social Factor Productivity, which includes the major externalities within the food chain. Generally, whilst TFP growth rates are low over the period 1998-2002, these have reduced even further when negative externalities are included.

Regulations relating to disease management have traditionally been an important component of the overall environment in which international trade in agriculture products occurs. The World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) allows members to restrict or prohibit imports from a country when imported products present a risk to human, animal or plant health or life. As the Bovine Spongiform Encephalopathy (BSE, also commonly called Mad Cow disease in the media) outbreak in Canada showed, the disease status of a country is a major competitive advantage and losing disease-free status can impose significant costs on an industry.

A transcriptomic approach of salinity response in the euryhaline teleost, Dicentrarchus labrax
Provedor de dados: 5
Autores: Boutet, Isabelle; Ky, Chin Long; Bonhomme, Francois.
Euryhaline teleosts possess the capacity to osmoregulate under various environmental conditions (freshwater to hypersaline water). This physiological capacity is generally monitored using enzyme activity assays (Na+/K+-ATPase...), hormones quantification (prolactine, growth hormone) or their mRNAs expression. To date, few studies addressed the genetic correlates of adaptation to varying salinity at a molecular level in such fish. In the sea bass Dicentrarchus labrax, genetic differentiation was observed at specific allozyme loci between lagoon- and open-sea populations. In the present study, we investigated transcriptomic response of D. labrax to salt- and freshwater acclimation in two organs involved in osmoregulation, gill and intestine. By using...

A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture
Provedor de dados: 31
Autores: Langyintuo,   Augustine S.; Hamazakaza,   Petan; Nawale,   Edah; Mekuria,   Mulugetta.
This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area.

A Unified Methodology for Estimating the Demand for Improved Seed at the Farm Level in Developing Agriculture
Provedor de dados: 31
Autores: Langyintuo,   Augustine S.; Mazuze,   Feliciano M.; Chaguala,   P.A.; Buque,   I.A.
This paper proposes a novel approach for estimating farm level seed demand in developing countries. In principle, a farmer views an improved seed as a derived input embodying production attributes and a technology embodying consumption characteristics and jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated improved seed adoption and demand models simultaneously using data collected from 300 randomly selected farm households in the Manica, Sussundenga and Chockwé districts of Mozambique in the 2003/04 crop season. The demand model results suggest that adoption rate, household...

Consuming market increasingly requires that companies assure higher quality products. These companies in turn are in search of solutions to meet such requirements, and thus consolidate their image and credibility with consumers. Such initiatives lead to gains and make these companies more competitive so as to figure prominently in the markets they operate. This article aims to understand how Netuno Pescados uses HACCP - HAZARD ANALYSIS AND CRITICAL CONTROL POINT system, in order to assure a high safety level to products delivered to markets it serves. This system is based on the principle that biological, chemical and physical dangers may exist in several points of the industry. However, preventive measures can be taken to control them and remove potential...

A Value Chain Task Force Approach for Managing Private-Public Partnerships:  Zamiba’s Task Force on Acceleration of Cassava Utilization.
Provedor de dados: 31
Autores: Chitundu,   Maureen; Droppelmann,   Klaus; Haggblade,   Steven.
Smallholder farmers operate in vertical supply chains. Therefore, an understanding of key opportunities and constraints up through the value chain becomes necessary for sustaining smallholder growth. Yet market analysis is of little value unless key private and public sector stakeholders agree to implement necessary reforms. This paper advocates an approach which marries together value chain analysis with a stakeholder taskforce to ensure that analysis of opportunities and constraints gets translated into actions that will facilitate commercial growth. Using Zambia’s cassava task force as an example, the paper describes the value chain task force method and identifies elements critical to its effective implementation.

A variabilidade espacial das famílias de Coleoptera (Insecta) entre fragmentos de Floresta Ombrófila Mista Montana (Bioma Araucária) e plantação de Pinus elliottii Engelmann, no Parque Ecológico Vivat Floresta, Tijucas do Sul, Paraná, Brasil
Provedor de dados: 104
Autores: Ganho,Norma G.; Marinoni,Renato C.
Várias questões sobre a biodiversidade vêm sendo levantadas nas últimas décadas. Uma delas é o papel que as plantações florestais exóticas monoculturais desempenham na manutenção da fauna nativa, principalmente de insetos. Estudos têm demonstrado que os Coleoptera são sensíveis a variações florísticas e estruturais, em pequena escala espacial. Para analisar as possíveis diferenças na diversidade de Coleoptera entre um ambiente de floresta natural e uma plantação florestal exótica monocultural foi desenvolvido um inventário no Parque Ecológico Vivat Floresta, Tijucas do Sul, Paraná. Para tanto, durante 52 semanas (agosto de 2004 a julho de 2005), seis armadilhas malaise foram dispostas ao longo de um transecto através de dois ambientes adjacentes, com...

A Variation of Phrenic Nerve: Case Report and Review
Provedor de dados: 77
Autores: Prakash,; Prabhu,Latha V; Kumar,Jwalaram; Madhyastha,Sampath; Singh,Gajendra.
During routine dissection in the Department of Anatomy following anatomical variations of phrenic nerve were observed on right side in the neck region of a middle aged cadaver. The phrenic nerve in its early course close to its origin was giving a communicating branch to C5 root of brachial plexus and at the level of the root of neck just before entering the thorax, the phrenic nerve was placed anterior to the subclavian vein. This unique case of phrenic nerve variation gains tremendous importance in context of subclavian vein cannulation, implanted venous access portals, and supraclavicular nerve block for regional anesthesia

A vitivinicultura brasileira e sua dependência de uma política setorial adequada.
Provedor de dados: 14
Autores: PROTAS, J. F. da S.
o setor vitivinícola brasileiro, a despeito das dificuldades impostas pela forte concorrência dos produtos importados no mercado interno e reagindo a este cenário, vêm nos últimos anos, num processo crescente de articulação interinstitucional, envolvendo todos os elos da cadeia produtiva nos seus diferentes segmentos (vinhos e espumantes finos, vinhos de mesa, suco de uva e uva de mesa), com vistas a adequação organizacional do setor. Exemplo emblemático deste processo foi a elaboração, por parte do Instituto Brasileiro do Vinho - IBRA VIN e SEBRAERS, no período entre 2004 e 2005, do Programa de Desenvolvimento Estratégico da Vitivinicultura do Rio Grande do Sul, estado maior produtor de uvas e vinhos do Brasil.

A Weak Bargaining Set for Contract Choice Problems
Provedor de dados: 31
Autores: Lahiri,   Somdeb.
In this paper, we consider the problem of choosing a set of multi-party contracts, where each coalition of agents has a non-empty finite set of feasible contracts to choose from. We call such problems, contract choice problems. The main result of this paper states that every contract choice problem has a non-empty weak bargaining set. The need for  such a solution concept which is considerably weaker than the core arises, since it is well known that even for very simple contract choice problems, the core may be empty. We also show by means of an example that the bargaining set due to Mas-Colell (1989), as well as a weaker version of it, may be empty for contract choice problems, thereby implying that the weakening we suggest is in some ways “tight”

Abatement Cost Heterogeneity and its Impact on Tradable Nitrogen Discharge Permits
Provedor de dados: 31
Autores: Ramilan,   Thiagarajah; Scrimgeour,   Frank G.
Nitrogen discharge into the Waikato River has been identified as the primary source of potential water quality degradation. Rising nitrogen levels in water are attributed to non point source pollution from agricultural activities. Pastoral farming is the predominant agricultural land use in the catchment. Increased nitrogen fertilizer use and higher stocking rates have the potential to increase the nitrogen loading into water. There is a range of best management practices and policies proposed to reduce nitrogen discharge from farming systems. Water quality trading is a policy tool that could improve the cost effectiveness of achieving environmental goals. Economic theory suggests that tradable pollution permit systems encourage polluters to reallocate...

Abatement costs for agricultural nitrogen and phosphorus loads: a case study of crop farming in south-western Finland
Provedor de dados: 21
Autores: Helin, Janne; Laukkanen, Marita; Koikkalainen, Kauko.
Designing efficient agri-environmental policies for agricultural nutrient load reductions calls for information on the costs of emission reduction measures. This study develops an empirical framework for estimating abatement costs for nutrient loading from agricultural land. Nitrogen abatement costs and the phosphorus load reductions associated with nitrogen abatement are derived for crop farming in south-western Finland. The model is used to evaluate the effect of the Common Agricultural Policy reform currently underway on nutrient abatement costs. Results indicate that an efficiently designed policy aimed at a 50% reduction in agricultural nitrogen load would cost € 48 to € 35 million, or € 3756 to € 2752 per farm.

Abnormal spindle orientation during microsporogenesis in an interspecific Brachiaria (Gramineae) hybrid
Provedor de dados: 74
Autores: Mendes-Bonato,Andréa Beatriz; Pagliarini,Maria Suely; Valle,Cacilda Borges do.
This paper reports a case of abnormal spindle orientation during microsporogenesis in an interspecific hybrid of the tropical grass Brachiaria. In the affected plant, prophase I was normal. In metaphase I, bivalents were regularly co-oriented but distantly positioned and spread over the equatorial plate. In anaphase I, chromosomes failed to converge into focused poles due to parallel spindle fibers. As a consequence, in telophase I, an elongated nucleus or several micronuclei were observed in each pole. In the second division, the behavior was the same, leading to polyads with several micronuclei. A total of 40% of meiotic products were affected. The use of this hybrid in production systems needing good-quality seeds is discussed.

About the Efficiency of Input vs. Output Quotas
Provedor de dados: 31
Autores: Merel,   Pierre R.
Output quotas are known to be more efficient than input quotas in transferring surplus from consumers to producers. Input quotas, by distorting the shadow prices of inputs, lead to inefficient production and generate larger deadweight losses, for a given amount of surplus transferred. Yet, input quotas have been a ubiquitous tool in agricultural policy. Practicality considerations, as well as the difficulty to control outputs that heavily depend on stochastic weather conditions, are arguments that help understand why policy makers may favor input quotas over output quotas. In this paper, we offer an additional explanation that rests on efficiency considerations. Assuming that the regulator only has limited knowledge about the market fundamentals (supply...

Absence of both glutathione perioxidase activity and glutathione in bovine milk
Provedor de dados: 21
Autores: Stagsted, J.
Glutathione peroxidases are selenium-dependent, antioxidant enzymes that catalyse the removal of hydroperoxides using the tripeptide glutathione as reducing substrate. The presence and importance of glutathione peroxidase for the oxidative stability of bovine milk is unclear. We failed to detect any specific activity in bovine milk using careful and comprehensive assay conditions. The apparent activity in milk that has been ascribed previously to glutathione peroxidase was shown to be independent of added hydroperoxide, completely inhibited by &gt;6 mM EDTA, and could not be immunoprecipitated with a specific antiserum against the extracellular form of glutathione peroxidase. These results are incompatible with activity of glutathione peroxidase in bovine...

The plant Croton cajucara Benth. (Euphorbiaceae) is a medicinal plant from the Brazilian Amazon where it is commonly known as sacaca. The principal compound isolated from C. cajucara stem-bark extracts is the clerodane-type diterpene trans-dehydrocrotonin (DCTN) which presents several biological activities, including antiulcerogenic, anti-inflammatory, hypoglycemic, antimutagenic and antitumoral activity. However, few studies have been carried out to evaluate the therapeutic potential of raw C. cajucara extracts. We studied mutagenicity and antimutagenicity effects of C. cajucara methanol extract using the micronucleus assay in bone marrow cells and the dominant lethal assay in mice submitted to subchronic treatments. The blood testosterone levels of the...

Absorbed dose measurements using TLDS in biological samples from beta radiation
Provedor de dados: 52
Autores: Manzoli,José Eduardo; Carvalho,Valdir de Souza; Cerqueira,Eliomar Jacinto Gomes de.
Irradiation of samples in peculiar experimental apparatus, subject to radiation spread, requires a special evaluation of absorbed dose implanted to the sample. Indirect calibration of the irradiation source, obtained in a different apparatus, and the spread, usually of very difficult theoretical evaluation, can cause very serious measurement errors, sometimes reaching 50%. In this work, the procedure for dose evaluation in an apparatus for beta irradiation of samples, usually biological ones,is presented, making use of calibration curves, obtained by irradiation in advance of thermoluminescent detectors in air, and so irradiating them in the same position of the sample. An application in blood sample irradiation is also presented.

O objetivo do experimento foi avaliar o desempenho de dezoito genótipos de arroz quanto a absorção de P, Mg, Ca e K e identificar genótipos com bom desempenho quando submetidos ao estresse por Al3+ em sistema hidropônico. Foram utilizados quatro níveis de Al3+ (0, 10, 20 e 30mg L-1) e o delineamento experimental foi blocos casualizados com três repetições. As plântulas permaneceram em sistema hidropônico por 20 dias sob efeito dos tratamentos, e após foram avaliadas quanto ao comprimento de raízes (CR) e teores de P, Mg, Ca e K. Todas as variáveis apresentaram reduções significativas nos seus valores, e os genótipos...

Provedor de dados: 86
Autores: Justino,Gilberto Costa; Cambraia,José; Oliva,Marco Antonio; Oliveira,Juraci Alves de.
O objetivo deste trabalho foi estudar os efeitos do alumínio (Al) sobre a absorção e a redução de nitrato, em duas cultivares de arroz: Fernandes (tolerante) e Maravilha (sensível), expostas a 0 e 500 µM de Al. Depois de 21 dias de crescimento, foram determinados o comprimento, a produção de matéria seca, os teores de Al e de nitrato e a atividade in vitro da redutase do nitrato (RN), nas raízes e na parte aérea, bem como as constantes cinéticas de absorção de nitrato pelas raízes. O Al reduziu o crescimento em comprimento e a produção de matéria seca, nas duas partes das plantas, apenas da cultivar Maravilha. Os teores de Al aumentaram nas raízes e parte aérea das plantas nas duas cultivares, enquanto o teor de nitrato sofreu redução apenas nas raízes da...

Abundance, feeding and reproduction of Salminus sp. (Pisces: Characidae) from mountain streams of the Andean piedmont in Venezuela
Provedor de dados: 83
Autores: Rodríguez-Olarte,Douglas; Taphorn B.,Donald C.
To obtain basic information for management, aspects of the ecology of Salminus sp. (Pisces: Characidae), were studied in piedmont rivers of the southwestern flank of the Andes in Venezuela. Collections were made with seines of various lengths and mesh sizes, and both underwater and terrestrial observations were recorded to estimate abundance and feeding events. Interviews with local fishermen and inhabitants were made to obtain data on use. The species is present along the entire length of the Andean piedmont in Venezuela, although in some rivers it is now scarce. Small individuals form mixed schools with Brycon whitei, but larger Salminus sp. usually only school with others of the same species. Average abundance was greater in larger rivers, and didn't...

Abundância, sobrevivência e crescimento de plântulas de Ipomoea pes-caprae (L.) R. Br. (Convolvulaceae) na Ilha de Santa Catarina, SC, Brasil
Provedor de dados: 39
Autores: Castellani,Tânia Tarabini; Santos,Flávio Antonio Maës dos.
Plântulas de Ipomoea pes-caprae ocorreram em nove das dez praias estudadas na Ilha de Santa Catarina, SC, e em 21 das 30 manchas monitoradas, não ocorrendo na praia de menor extensão. Suas densidades variaram de 0 a 5,2 plântulas m², sendo estas diferenças em parte explicadas pela densidade de sementes viáveis no solo. A sobrevivência de plântulas foi baixa, 0,6%, se considerarmos as 2.823 plântulas acompanhadas em três anos. Os principais fatores de morte foram a erosão e o soterramento marinhos. Nenhuma plântula sobreviveu no setor de alta praia (n = 2684). Houve sobrevivência em duna frontal, sob mancha estabelecida (0,8%, n = 119), em área em recolonização, onde os indivíduos foram parcialmente removidos (80,0%, n = 20) e em áreas recentes,...

Wühlmausschäden sind weit verbreitet und gehören zu den nur schwer lösbaren Pflanzenschutzproblemen im ökologischen Landbau. Nach einer Umfrage des Institutes für  Nematologie und Wirbeltierkunde der Biologischen Bundesanstalt für Land- und Forstwirtschaft (BBA), im Jahre 2002 waren 90 % der befragten Obstbaubetriebe von Wühlmausschäden betroffen. Als Hauptschadensverursacher treten vor allem die Schermaus  (Arvicola terrestris ), auch große Wühlmaus genannt, und die Feldmaus ( Microtus arvalis) auf. Mit den wenigen zur Verfügung stehenden Mitteln erreicht aber nur ein Bruchteil der ökologisch wirtschaftenden Betriebe einen akzeptablen Bekämpfungserfolg.

Acaciapollenites acaciae sp. nov., a new mimosoid polyad species from the Neogene of Colorado Basin, Argentina
Provedor de dados: 41
Autores: Caccavari,Marta A.; Guler,M. Verónica.
Fossil mimosoid polyads have been recently recovered from Neogene deposits in the Colorado Basin, Argentina, and the new species Acaciapollenites acaciae sp. nov. is described, which is closely similar to polyads of species included in Acacia Miller subgenus Acacia Vassal. It is characterized by colporate apertures on the distal face of the pollen grains, a typical polyad of the subgenus Acacia. The new polyad species is very similar to those of the extant Acacia curvifructa Burkart. Comparing the habitat of subgenus Acacia extant species, the Acaciapollenites acaciae occurrence suggests drier and warmer paleoclimatic conditions than today for the Late Miocene-Early Pliocene in the Colorado Basin. Paleogeographic data of Acacia pollen diversity are...

Resilience is a vital attribute that characterizes a system&amp;#8217;s capacity to cope with stress. Researchers have examined the measurement of resilience in ecosystems and in social&amp;#8211;ecological systems, and the comparative vulnerability of social groups. Our paper refocuses attention on the processes and relations that create social resilience. Our central proposition is that the creation of social resilience is linked to a community&amp;#8217;s ability to access critical resources. We explore this proposition through an analysis of how community resilience to the stress of water scarcity is influenced by historically contingent mechanisms to gain, control, and maintain access to water.  Access is defined broadly as the ability of a community...

Access of Eastern African Farmers to Domestic and International Markets: Opportunities and Constraints
Provedor de dados: 31
Autores: Bahiigwa,   Godfrey.
This paper reviews the opportunities and challenges that Eastern African farmers face in accessing domestic, regional and international markets. With rising population and incomes, domestic markets offer great opportunities for farmers. However, because of structural, institutional and organizational constraints, small scale rural farmers may not benefit much from domestic urban markets unless they are organized and trained to meet the high quality product standards demanded by urban consumers and supermarkets. ECA countries stand to gain more by investing in commodities that are consumed within the region, than from traditional cash crops destined for international markets. Regional integration offers opportunities for larger markets and efficiency gains...

Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes
Provedor de dados: 31
Autores: Escobal D'Angelo,   Javier; Torero,   Maximo.
The purpose of this study is twofold. On one hand, the objective is to assess the impact of new and more complex contracting schemes, as opposed to traditional marketing channels, on small farmers’ welfare. On the other hand, the study explores which may be the critical factors that determine the small farmers’ participation in these institutional arrangements. In this context, two critical factors are stressed. The first one has to do with access to credit and the second one is the size of the agricultural plot. In order to examine the decision of farmers to access the dynamic markets, the paper follows the study of Lapar et al (2003). The paper also follows impact evaluation techniques to identify the differences in the performance of farmers with access...

Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes
Provedor de dados: 31
Autores: Escobal D'Angelo,   Javier; Torero,   Maximo.
The study has evaluated which are the most relevant factors that determine that a small farmer switch marketing channels in order to enter into a "dynamic" market; that is, into a market signed by more complex contractual relationships that can absorb increasing amounts of its output. The results show that there are a number of producers that currently are not selling to those markets but they may well do so. Restrictions associated to the degree of organization of the producers, their perception of risk and credit market restrictions may prevent these farmers to gain access to the additional benefits that these new market opportunities have to offer.

Access to Land, Income Diversification and Poverty Reduction in Rural Kenya
Provedor de dados: 31
Autores: Karugia,   Joseph Thuo; Oluoch-Kosura,   Willis; Nyikal,   Rose Adhiambo; Odumbe,   Michael; Marenya,   Paswel Phiri.
The increasing land scarcity and the worsening trend of poverty in Kenya in recent years have raised concerns about the focus on land-based agriculture as the basis of growth in the rural areas. This paper combines two complementary data sets obtained from two locations in Kenya, drawn against distinctively different land availability patterns, to examine the diverse rural asset base and key sources of livelihood in the rural areas. The analysis reveals that while access to productive land is still an important determinant of livelihoods in the rural areas, even where land holdings are very small, growth in farm productivity alone may not guarantee households sufficient incomes to escape poverty. We find evidence to suggest that growth of non-farm sector...

Accounting for Impact of Environmental Degradation in Agriculture of Indian Punjab
Provedor de dados: 31
Autores: Singh,   Joginder; Sidhu,   R.S.
Having witnessed a fast growth, the agriculture in Punjab has reached a plateau. To sustain even the existing level, the costs are increasing and natural resources are being depleted due to overuse. This study has examined the use of certain resources and its impact on the cost of production. The data have been collected from different primary and secondary sources. The fast increase in area under rice and wheat appears to be unsustainable due to the fast decline in water table. Therefore, the cost of pumping out water with electricity has been going up, shortage of electric power has resulted in increase in the number of electric and diesel tubewells, further escalating the cost of production. The replenishment of soil health due to depleting macro and...

Accounting standards for supply chains
Provedor de dados: 26
Autores: Bremmers, H.
In this paper principles for accounting in supply chains will be developed. The three principles we introduce are: the reciprocity in information access, asset investment and retrieval, and matching risks and returns. The principles provide guidance in managerial and stakeholder decision making, monitoring and control. The information that management and other stakeholders need is based on these standards. The use of the supply-chain accounting principles increases transparency. Transparency is one of the main elements of what Fowler et al (2004) call ‘virtually embedded ties’. We argue that transparency should replace, or at least supplement, relational trust in supply channels. We argue also that technological innovation, such as electronic chain-wide...

Autores: Richards,   Christine L.; Morgan,   Christopher K.; Baldwin,   Basil J.
The practices products and resource management of Australia’s farm managers and their environmental consequences are being closely scrutinised by the community. Accreditation is an approach increasingly being used to monitor these matters across agricultural industries. Quality Assurance and Environmental Management Systems have gained prevalence as a means of validating activity and providing evidence of meeting stewardship responsibilities. This paper reviews the range of programs and systems available to primary producers across Australia. In this review it is argued that the growth of these accreditation systems has given rise to confusion, duplication, and increased management and industry costs, with limited assurances to customers and the community...

Accruals, Free Cash Flows, and EBITDA for Agribusiness Firms
Provedor de dados: 31
Autores: Trejo-Pech,   Carlos Omar; Weldon,   Richard N.; House,   Lisa; Salas-Gutierrez,   Tomas.
This study explores the relationships between the accrual and cash flow components of earnings for agribusiness. Three accrual models with their respective cash flows, free cash flows, and free cash flows to equity are analyzed. Results for the agribusiness industry are compared with results from previous studies of all firms. Earnings Before Interests, Taxes, Depreciation, and Amortization (EBITDA), a measure frequently recommended as a proxy for cash flow is tested using these models. Empirical results show that both the magnitude and the behavior of EBITDA differ from cash flows and should not be used as a proxy.

Rice germ contains protein, vitamins, minerals, dietary fiber and gamma-aminobutyric acid (GABA). GABA has been proved to be effective for lowering the blood pressure of human being. It has neurotransmission functions and tranquilizer effects. determination of GABA in rice germ and brown rice were investigated by using low-amylose, high-amylose and waxy rice cultivars. Percentage of germ weight showed no relation to the GABA content. The amount and patterns of the GABA accumulation varied depending on the cultivar. GABA content in most of rice varieties increased during incubation.

Accuracy of Numerical Solution to Dynamic Programming Models
Provedor de dados: 31
Autores: King,   Robert P.; Lohano,   Heman D.
Dynamic programming models with continuous state and control variables are solved approximately using numerical methods in most applications. We develop a method for measuring the accuracy of numerical solution of stochastic dynamic programming models. Using this method, we compare the accuracy of various interpolation schemes. As expected, the results show that the accuracy improves as number of nodes is increased. Comparison of Chebyshev and linear spline indicates that the linear spline may give higher maximum absolute error than Chebyshev, however, the overall performance of spline interpolation is better than Chebyshev interpolation for non-smooth functions. Two-stage grid search method of optimization is developed and examined with accuracy analysis....

Achieving fat score targets: the costs and benefits
Provedor de dados: 31
Autores: Graham,   Phillip; Hatcher,   Sue.
The national Lifetime Wool project has quantified the production benefits that accrue to a breeding flock of Merino ewes from actively managing their fat score at critical stages of the reproductive cycle. The GrassGro™ model was used to simulate the profitability of achieving three fat score targets (i.e. FS2.5, FS3-4% lambing and FS3-10% lambing) for a predominately grazing region (Yass) of NSW and a sheep/cereal region (Parkes). In both regions the FS3-10% flock had the highest gross margin but was also the riskiest option in terms of the variation in gross margin during the simulation period. In all cases the key driver of gross margin was the amount (and therefore cost) of supplement required to meet the fat score targets which highlights the...

Acidification of the parasitophorous vacuole containing Toxoplasma gondii in the presence of hydroxyurea
Provedor de dados: 42
Autores: Carvalho,Cristiane S.; Melo,Edésio J.T.
Toxoplasma gondii multiplies within parasitophorous vacuole that is not recognized by the primary no oxidative defense of host cells, mainly represented by the fusion with acidic organelles. Recent studies have already shown that hydroxyurea arrested the intracellular parasites leading to its destruction. In the present work we investigated the cellular mechanism involved in the destruction of intracellular Toxoplasma gondii. Fluorescent vital stains were used in order to observe possible acidification of parasitophorous vacuole-containing Toxoplasma gondii in presence of hydroxyurea. Vero cells infected with tachyzoites were treated with hydroxyurea for 12, 24 or 48 hours. Fluorescence, indicative of acidification, was observed in the parasitophorous...

O objetivo deste trabalho foi avaliar o efeito da inclusão do farelo de coco (FC) na ração e do tempo de alimentação de poedeiras comerciais, sobre os ácidos graxos da gema e os componentes do ovo. O delineamento foi em esquema fatorial 5x2, com cinco níveis de inclusão do FC (0, 5, 10, 15 e 20%) e dois tempos de alimentação (14 e 28 dias). Foram avaliados o peso e as porcentagens de albúmen, gema e casca dos ovos, bem como os sólidos e lipídios totais e o perfil de ácidos graxos das gemas. A inclusão do FC e o tempo de alimentação influenciaram apenas a proporção de ácido mirístico na gema, que aumentou com a inclusão do FC aos 28 dias de alimentação. Os ácidos esteárico e oléico variaram somente com o tempo de alimentação, e as maiores concentrações...

Ackerbohnenschrot im Vergleich zu Rottemist: Effekte auf Ertrag und Qualitätsparameter von Kartoffeln
Provedor de dados: 21
Autores: Oltmanns, Meike; Raupp, Joachim.
Ökologische Betriebe ohne eigene Viehhaltung müssen eine Düngungsalternative für Stallmist finden. Im Gemüse- oder Feldgemüseanbau sind dies meist geschrotete, großkörnige Leguminosensamen. Während die Wirkungen des Stallmistes in vielen Feldversuchen bereits belegt worden sind, stehen entsprechende Untersuchungen mit Leguminosenschroten noch aus. Daher werden seit 1996 in einem Feldversuch die Langzeit-Effekte von pflanzlichen organischen Düngern und Stallmist sowie Mineraldüngung (bei gleicher Stickstoff-Aufwandmenge, 100 kg ha-1 N) verglichen.    Ergebnisse in 2005: Der Ertrag der marktfähigen Kartoffeln lag bei den Düngungsarten Stallmist und Ackerbohnenschrot mit ca. 230 dt ha-1 gleich hoch.

Ackerwildkräuter als „ökologische Leistung“ – Entwicklung einer Methode zur Feststellung förderwürdiger, artenreicher Ackerflächen
Provedor de dados: 21
Autores: Braband, D.; van Elsen, T.
Die floristische Diversität wird immer häufiger als Indikator für eine naturgerechte Bewirtschaftung genutzt. Während sie in Grünlandsystemen bereits Grundlage zur Honorierung besonderer ökologischer Leistungen (z.B. in der Schweiz und in Baden-Württemberg) ist, wird die Wildkraut-Artenvielfalt auf Äckern erst anfänglich als honorierbare ökologische Leistung diskutiert. Im Rahmen eines Forschungsprojektes  zur Erfassung biotischer Leistungen auf landwirtschaftlicher Betriebsebene wurde u.a. auch eine Methode erarbeitet, welche die pflanzliche Biodiversität von Ackerflächen berücksichtigt. In dem Beitrag werden die Entwicklung der Methode und ihre Anwendung dargestellt. Dabei beruht die Einstufung als artenreiche Ackerfläche auf dem Vorhandensein...

Autores: Hotze, C.; van Elsen, T.
Das östliche Meißnervorland in Nordhessen ist als besonders artenreiches Refugium selten gewordener Ackerwildkräuter bekannt. Auf den bereits 1975 und 1990 floristisch gut untersuchten Ackerflächen wurden mit 348 Vegetationsaufnahmen im Jahre 2002 erneut Daten zur aktuellen Segetalvegetation erhoben. Die pflanzensoziologische Vergesellschaftung der Arten und deren Entwicklung wird, differenziert für die Rand- und Innenbereiche der Felder, vorgestellt.  Seltene Pflanzengemeinschaften, wie z.B. die Haftdolden-Adonisröschen-Gesellschaft, sind nach wie vor im Gebiet vorhanden, jedoch zunehmend floristisch verarmt und beschränkt auf die Randbereiche von Feldern. Gut zwei Drittel der Aufnahmen im Innenbereich der Flächen lassen sich heute aus Mangel an Arten...

AÇÕES COLETIVAS ENVOLVENDO PEQUENOS PRODUTORES: DA EXCLUSÃO À INCLUSÃO NOS MERCADOS
Provedor de dados: 194
Autores: Lourenzani, Ana Elisa Bressan Smith; Silva, Andrea Lago da.
De forma a oferecer produtos em conformidade com os novos padrões competitivos, os produtores rurais de pequeno porte tiveram que se adaptar às novas demandas de mercado como exigências relacionadas,principalmente, à qualidade, regularidade no fornecimento, escala mínima de fornecimento, preço e agilidade logística. No entanto, observa-se que essas mudanças refletiram fortemente sobre pequenos produtores rurais. Muitos se mostraram incapazes de atender às novas demandas do mercado devido às características intrínsecas à pequena unidade de produção. Essa situação aumentou o risco de ocorrência de processos de exclusão de pequenos produtores da atividade agrícola. Uma possibilidade que se apresenta é a adoção de ações coletivas, buscando possibilitar a...

Acordos comerciais e o setor produtivo de carne bovina: estimativas de ganhos para o Mercosul
Provedor de dados: 31
Autores: Waquil,   Paulo Dabdab; Alvim,   Augusto Mussi.
This study identifies the effects of free trade agreements at the multilateral (WTO) and regional (FTAA and MERCOSUR-EU) levels on the bovine meat markets in several regions. In order to evaluate these effects, we used a spatial allocation model, presented as a mixed complementarity problem (MCP). The study identifies the changes in production and consumption levels, as well as the changes in producer and consumer surplus, in four possible scenarios. In general, gains to bovine meat producers in the MERCOSUR countries are expected in all scenarios. Although, these gains are greater when we simulate a multilateral trade liberalization, with or without the elimination of subsidies.

Acoustic characterisation of pelagic fish aggregations around moored fish aggregating devices in Martinique (Lesser Antilles)
Provedor de dados: 5
Autores: Doray, Mathieu; Josse, Erwan; Gervain, Paul; Reynal, Lionel; Chantrel, Josselin.
Sea cruises were conducted for 57 days over 16 months to characterise pelagic fish aggregations around 2 moored fish aggregating devices (FADs) in Martinique (Lesser Antilles). Echosounder surveys run in a star pattern were used in conjunction with obliquely beamed sonar observations. An echo-integration-by-shoal algorithm was implemented to isolate pelagic fish shoals from sound scattering layers and to compute mean morphometric, positional and density parameters. Tree regressions were used to select and classify pelagic fish Target Strengths (TS), with reference to their spatial and temporal characteristics. The main type of pelagic fish aggregation was a large sub-surface aggregation. It was observed during all daytime periods within a radius of 400 m...

Acoustical monitoring of fish density, behavior, and growth rate in a tank
Provedor de dados: 5
Autores: Conti, Stéphane; Roux, Philippe; Fauvel, Christian; Maurer, Benjamin; Demer, David.
A challenge for the aquaculture community has long been the development of harmless techniques for monitoring fish in a tank. Acoustic telemetry has been used to monitor fish swimming behavior, and passive acoustics have been used to monitor fish feeding, but new techniques are needed to monitor non-invasively their numbers and growth rates. Recently, it has been demonstrated that the acoustical total scattering cross section of fish swimming in a tank can be measured from multiple reverberation time series. These measurements have been used successfully to estimate the number of fish in a tank in laboratory conditions, and to characterize their acoustical signatures. Here, we introduce a novel method for acoustically monitoring fish numerical density and...

Action of calcium binders.: Formation of calcium salts in the intestinal tract and the blood circulatory system
Provedor de dados: 38
Autores: Martínez Yaquelo,César.
Calcium binders are water- soluble substances whose anionic part can possibly react with calcium cations present in any part of the human body. Some examples of calcium binders are phosphoric, oxalic and phytic acids and their alkaline salts present in many natural foods, in some foods containing additives, and in some medicines. There are also uric and lactic acids that are the result of normal metabolism. The first negative action of calcium binders takes place in the intestinal tract when they react with calcium of dairy food. The latter produces a combination of calcium binder anions with calcium cations, and then an insoluble salt that precipitates as small solid particles that cannot be assimilated and which are eliminated in the faeces. The second...

Activation of neural cholecystokinin-1 receptors induces relaxation of the isolated rat duodenum which is reduced by nitric oxide synthase inhibitors
Provedor de dados: 56
Autores: Martins,S.R.; de Oliveira,R.B.; Ballejo,G.
Cholecystokinin (CCK) influences gastrointestinal motility, by acting on central and peripheral receptors. The aim of the present study was to determine whether CCK has any effect on isolated duodenum longitudinal muscle activity and to characterize the mechanisms involved. Isolated segments of the rat proximal duodenum were mounted for the recording of isometric contractions of longitudinal muscle in the presence of atropine and guanethidine. CCK-8S (EC50: 39; 95% CI: 4.1-152 nM) and cerulein (EC50: 58; 95% CI: 18-281 nM) induced a concentration-dependent and tetrodotoxin-sensitive relaxation. Nomeganitro-L-arginine (L-NOARG) reduced CCK-8S- and cerulein-induced relaxation (IC50: 5.2; 95% CI: 2.5-18 µM) in a concentration-dependent manner. The magnitude...

Activity of phosphorus of synthetic Fe-K-P compounds in superphosphate fertilizers as affected by pH and ionic strength
Provedor de dados: 90
Autores: Prochnow,Luís Ignácio; Biasioli,Gustavo Marques; Rodella,Arnaldo Antonio; Jesus,Sérgio Luís de; Montes,Célia Regina; Alleoni,Luís Reynaldo Ferracciú.
The concentration of orthophosphate ions released from Fe-K-P compounds (Fe3KH8(PO4)6 .6H2O and Fe3KH14(PO4)8 .4H2O) present in superphosphates increases with pH, which initially suggests that the agronomic effectiveness of P fertilizers containing high amounts of these compounds would also increase with soil pH but studies considering activity, instead of concentration, are necessary. With this purpose, both compounds were synthesized under laboratory conditions, characterized by elemental chemical analysis, optical microscopy, X ray diffractometry, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), and used in a solubility study. Solutions of 0.01, 0.05 and 0.1 mol L-1 NaCl with pH adjusted to 3.0, 4.0, 5.0, 5.5, 6.0, 6.5, 7.0...

Actual Media Reports on GM Foods and Chinese Consumers' Willingness to Pay for GM Soybean Oil
Provedor de dados: 31
Autores: Hu,   Wuyang; Zhong,   Funing; Ding,   Yulian.
Information has been proven to have significant impacts on consumers' behavior and willingness to pay (WTP). In this study, information on GM soybean oil is given in the form of real-life cases involving GM food. These cases recorded from actual media reports. Using a hybrid of the double-bounded and payment care elicitation approaches, Chinese consumers' WTP for soybean oil is examined both before and after these cases are presented to them. Results indicate that media reports on positive cases do not increase consumers' WTP significantly, while reports on negative cases drastically lower their WTP.

Acumulación de aminoácidos tipo micosporina (MAAs): biosíntesis, fotocontrol y funciones ecofisiológicas
Provedor de dados: 97
Autores: KORBEE,NATHALIE; FIGUEROA,FÉLIX L; AGUILERA,JOSÉ.
Los efectos nocivos que inducen la radiación UV en organismos acuáticos pueden ser aminorados a través de varios mecanismos de fotoprotección entre los que se encuentran la acumulación de sustancias que absorben radiación UV (fotoprotectores) y activación de sistemas antioxidantes. Entre los fotoprotectores descritos se encuentran los aminoácidos tipo micosporina (MAAs). En esta revisión se enfatiza sobre la capacidad fotoprotectora y antioxidante de estas sustancias. La función fotoprotectora de los MAAs puede deducirse de las características fotofísicas de estos compuestos. Es sabido que actúan como pantalla pasiva disipando térmicamente la energía UV absorbida. La acumulación de MAAs se induce tanto por radiación UV (UV-A y UV-B) como por luz azul...

Acúmulo de macro e micronutrientes nas folhas e caules do ramo produtivo da lichieira 'Bengal' durante um ano
Provedor de dados: 64
Autores: Salomão,Luiz Carlos Chamhum; Siqueira,Dalmo Lopes de; Pereira,Márcio Eduardo Canto.
Estudou-se a composição de macro e micronutrientes em folhas e caule do ramo produtivo da lichieira 'Bengal' no período de julho de 1997 a setembro de 1998. Foram amostrados, quinzenal ou semanalmente, ramos do último surto de crescimento anterior a julho de 1997. A composição mineral de folhas e caule variou com o avanço da idade ocorrendo tendências de redução das quantidades de N, P, K, S, Fe, Cu, Zn e Mn nas folhas do início da amostragem até o final do florescimento. Do mesmo modo, o conteúdo foliar de todos os nutrientes, à exceção de Ca, Mg, Fe e Mn, reduziu-se nas folhas no período de emissão de novo surto de crescimento ocorrido a partir de fevereiro de 1998, após a colheita dos frutos. Isso indica a translocação daqueles nutrientes para os novos...

Acute pancreatitis and acute renal failure following multiple hornet stings
Provedor de dados: 80
Autores: Sharma,N.; Balamurugeshan,P. K.; Sharma,A.
Hymenoptera is a class of insects that sting in order to subdue their prey. Humans coming into accidental contact with these insects results in stings that may cause from mild local reaction like weal formation around the sting site to severe systemic reactions such as intravascular hemolysis, acute renal failure, pulmonary edema, cerebral edema, and rarely pancreatitis. We report here the clinical course of a patient who developed concurrent acute pancreatitis and pigment-induced acute renal failure after multiple hornet stings.

Acylsugars present in the accession 'LA716' of Lycopersicon pennellii play an important role in the resistance to Tuta absoluta. This paper investigates the possible association between the resistance to T. absoluta and the acylsugar contents in F2 and F2BC1 tomato plants derived from the interspecific crossing between L. esculentum 'TOM-584' and L. pennellii 'LA716'. From the F2 population, four high acylsugars and one low acylsugars plants were selected and tested for Tuta absoluta resistance along with parental lines TOM-584 and LA-716, and with the checks TOM-600 (high 2-tridecanone line with resistance to T. absoluta) and TOM-556 (low acylsugar line). The genotypes were tested under natural field infestation and were evaluated for overall plant...

Autores: Elmnasser, Noura; Ritz Bricaud, Magali; Guillou, Sandrine; Leroi, Francoise; Orange, Nicole; Bakhrouf, Amira; Federighi, Michel.
Listeria monocytogenes is it psychrotrophic food-borne pathogen. This organism is problematic for food production industry due to its ubiquitous distribution ill nature and its tolerance to condition of osmotic and chill stress. One common strategy employed by many bacteria and by L. monocytogenes for adaptation to osmotic stress is by the intracellular accumulation of compatible solutes. Two different types of adaptative reponses to low temperature have undertaken by L. monocytogenes. One of the responses is accomplished by adjusting membrane fluidity through alteration of the membrane fatty acid composition. A second response consists ill the accumulation of osmolytes. In this brief review we will focus on these general systems Which are Of particular...

Adaptive Management Planning Projects as Conflict Resolution Processes
Provedor de dados: 7
Autores: Walkerden, Greg; Macquarie University; gmw@bwassociates.com.au.
Adaptive management planning projects use multiparty, multidisciplinary workshops and simulation modeling to facilitate dialogue, negotiation, and planning. However, they have been criticized as a poor medium for conflict resolution. Alternative processes from the conflict resolution tradition, e.g., principled negotiation and sequenced negotiation, address uncertainty and biophysical constraints much less skillfully than does adaptive management. When we evaluate adaptive management planning using conflict resolution practice as a benchmark, we can design better planning procedures. Adaptive management planning procedures emerge that explore system structure, dynamics, and uncertainty, and that also provide a strong negotiation process, grounded in...

Addressing the specific needs of organic farming in the New EU Member States by the Rural Development Programmes 2007-2013
Provedor de dados: 21
Autores: Slabe, Anamarija; Häring, Anna Maria; Hrabalova, Andrea.
In all New EU Member States (NMS) and Candidate Countries (CCs) there is a lack of support measures for organic farming, other than area pay-ments, and there is no coherent policy for organic farming in general. The most significant problem areas are the general policy environment, underde-veloped marketing and processing, an almost total lack of information measures, insufficient and inap-propriate organic production capacity, and a lack of training and advisory services. The latest EU regula-tion on support for rural development provides a framework for a variety of measures to assist the development of organic farming and is therefore an important instrument for policy-makers, together with national action plans for organic farming. The problem issues...

Adenosine A1 receptor-mediated inhibition of in vitro prolactin secretion from the rat anterior pituitary
Provedor de dados: 56
Autores: Picanço-Diniz,D.L.W.; Valença,M.M.; Antunes-Rodrigues,J.
In previous studies, we demonstrated biphasic purinergic effects on prolactin (PRL) secretion stimulated by an adenosine A2 agonist. In the present study, we investigated the role of the activation of adenosine A1 receptors by (R)-N6-(2-phenylisopropyl)adenosine (R-PIA) at the pituitary level in in vitro PRL secretion. Hemipituitaries (one per cuvette in five replicates) from adult male rats were incubated. Administration of R-PIA (0.001, 0.01, 0.1, 1, and 10 µM) induced a reduction of PRL secretion into the medium in a U-shaped dose-response curve. The maximal reduction was obtained with 0.1 µM R-PIA (mean ± SEM, 36.01 ± 5.53 ng/mg tissue weight (t.w.)) treatment compared to control (264.56 ± 15.46 ng/mg t.w.).

The dynamics in stock returns and the market return for 21 food and agribusiness firms are estimated in a threshold switching-regression framework.  Threshold adjustment levels and capital asset pricing model risk parameters are estimated and tested.  Results indicate risk parameters differ for alternative regimes and are not constant over time.  Accounting for periods of temporary disequilibrium leads to notably more stable risk measurement estimates.

Adopting Organic Agriculture: An Investigation Using the Theory of Planned Behaviour
Provedor de dados: 31
Autores: Hattam,   Caroline.
Certified organic production by small-scale farmers in developing countries is increasingly promoted as an opportunity to access a growing and dynamic market, while at the same time, enhance productivity and improve incomes. Nevertheless, adoption has been limited. The economics literature suggests profitability is the main constraint, however, the sustainable agriculture literature is inconclusive and considers attitudes of significant importance. Using the Theory of Planned Behaviour, this study investigates the psychological barriers to adoption using small-scale avocado producers from Michoacan, Mexico as a case study. The data is obtained from a household study carried out during 2004 and is modelled using an ordered probit model. Despite positive...

Adoption and Impact of Hybrid Wheat in India
Provedor de dados: 31
Autores: Matuschke,   Ira; Qaim,   Matin.
In the light of ongoing debates about the suitability of hybrid seeds for smallholder farmers, this paper analyzes the adoption and impact of hybrid wheat in India. Based on survey data we show that farmers can benefit significantly from the proprietary technology. Neither farm size nor the subsistence level influence the adoption decision, but access to information and credit matters. Moreover, willingness-to-pay analysis reveals that adoption levels would be higher if seed prices were reduced. Given decreasing public support to agricultural research, policies should be targeted at reducing institutional constraints, to ensure that resource-poor farmers are not bypassed by private sector innovations.

Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same...

Adoption of No-Tillage Practices, Other Conservation-Tillage Practices and Herbicide-Resistant Cotton Seed, and Their Synergistic Environmental Impacts
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Gao,   Qi; Larson,   James A.
If adoption of herbicide-resistant seed and adoption of conservation-tillage practices are determined simultaneously, adoption of herbicide-resistant seed could indirectly reduce soil erosion and adoption of conservation-tillage practices could indirectly reduce residual herbicide use and increase farm profits.  Our objective was to evaluate the relationship between these technologies for Tennessee cotton production.  Evidence from simultaneous estimation of a trinomial logit model for adoption of no-tillage, other conservation-tillage, and conventional-tillage practices and a binomial logit model for adoption of herbicide-resistant and conventional cotton seed suggests a simultaneous relationship.  The elasticity for acreage in herbicide-resistant seed...

Adoption of Soil Erosion Control Practices in Southern Spain Olive Groves
Provedor de dados: 31
Autores: Franco,   Juan Agustin; Calatrava-Leyva,   Javier.
This paper presents results from a survey carried out in 2005 among 147 olive tree farmers from the Alto Genil River Basin in Southern Spain regarding the adoption of soil conservation and management practices. Olive tree groves in South-eastern Spain's mountainous areas are subject to a high risk of soil erosion and have to incur in high costs of soil conservation. This results in great 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 conservation...

Adubação verde na produção orgânica de alface americana e repolho
Provedor de dados: 75
Autores: Fontanétti,Anastácia; Carvalho,Gabriel José de; Gomes,Luiz Antonio Augusto; Almeida,Karina de; Moraes,Sylvia Raquel G de; Teixeira,Cícero Monti.
Na produção de hortaliças orgânicas a utilização exclusiva de composto orgânico tem se mostrado uma prática onerosa, em função do grande volume exigido para se obter produções comerciais. Uma das alternativas para a adubação complementar das hortaliças é a utilização da adubação verde. O objetivo deste trabalho foi avaliar três espécies de adubos verdes, utilizadas em complementação ao composto orgânico, quanto ao aporte de nutrientes ao solo, a produtividade e às características agronômicas de alface americana e repolho.

Advantages and pitfalls of different types of studies for investigations of the impact of food on health
Provedor de dados: 21
Autores: Brandt, Dr Kirsten; Seal, Dr Chris.
Several types of studies can be used to elucidate various aspects of the effect of food on human health. The main categories are:  • Epidemiological (observational) studies with humans. These can be prospective, where the diet is recorded and health indicators are moni-tored after the first recording, or retrospective, where people who have a disease are identified and it is then investigated if their diet has been different from those who did not get the same disease.   • Intervention studies with animals or humans, where the outcome is differences in indicators of health between groups eating different controlled diets.   • In vitro studies, where specific aspects of the mechanisms of the effects of food or food com-ponents are studied in cell cultures,...

This report presents marketing profiles and loan deficiency payment/marketing loan gain profiles for the advisory services followed by the AgMAS Project for the 2002, 2003 and 2004 corn crops. Marketing profiles are constructed by plotting the cumulative net amount priced under each program’s set of recommendations throughout the crop year. Loan deficiency payment/marketing loan gain (LDP/MLG) profiles are constructed by plotting the cumulative percentage of the crop on which the LDP/MLG was claimed during the crop year.  Marketing profiles provide information to evaluate the style of advisory services in several ways. The percentage of crop priced is a measure of within-crop year price risk. The higher the proportion of a crop priced, the lower the...

Aedeagus morphology as a discriminant marker in two closely related Cactophilic species of Drosophila (Diptera; Drosophilidae) in South America
Provedor de dados: 42
Autores: Franco,Fernando F.; Prado,Pedro R.R.; Sene,Fábio M.; Costa,Luciano F.; Manfrin,Maura H.
Drosophila serido and D. antonietae are sibling species belonging to the Drosophila buzzatii cluster. Morphologically, they can only be discriminated by quantitative traits. In this paper we analyze the length and equalized average curvature of four regions of the aedeagus of D. antonietae and D. serido. Specimens of D. serido and D. antonietae were classified correctly 96.74% of the time. Based only on the variable that most contributed to the discrimination of the groups (equalized average curvature of the arch IV of the aedeagus), we observed significant intraspecific morphological divergence in D. serido in relation to the D. antonietae, in agreement with other markers. The high morphological divergence in equalized average curvature of the arch IV of...

Autores: Soest, R.W.M. van; Hooper, J.N.A.; Beglinger, E.; Erpenbeck, D.
Comparison of Sollasella digitata Lendenfeld, 1888, up until the present assigned to its own family Sollasellidae Lendenfeld, 1887 in the order Hadromerida, and Raspailopsis cervicornis Burton, 1959, assigned to Raspailiidae Nardo, 1833 in the order Poecilosclerida, leads to the conclusion that both should be considered congeneric and are best assigned to a single genus Sollasella. This conclusion is based on examination of habit and skeletal characters of the type material of S. digitata and both type and freshly collected material of S. cervicornis. The conclusion is strengthened by the discovery of a new species, Sollasella moretonensis n.sp. collected in North Australia (primarily in the northeastern coast, but also an isolated record from the...

Autores: Shundo,Luzia; Sabino,Myrna.
During 2002 and 2003, a total of 107 samples of raw, pasteurized and ultrahigh treated temperature (UHT) milk commercialized in the cities of São Paulo and Marília (SP) were analyzed for the presence of aflatoxin M1 (AFM1). AFM1 was detected in 79 (73.8%) of milk samples, ranging from &lt;0.02 to 0.26 mug/L.The samples were analyzed using an immunoaffinity column for cleanup and a thin layer chromatography for determining AFM1. The parameters, such as recovery, repeatibility, detection and quantification limit were evaluated to optimize this method (in-house). Based on spiked samples, the recovery values ranged from 85.83 to 73.86% at levels of 0.010-0.50 mug/L, respectively, and the relative standard deviation for repeatibility ranged from 7.73 to 2.08%....

Age et croîssance du chinchard à quelque jaune (trachurus méditerraneus) dans la région nord de la Tunisie
Provedor de dados: 20
Autores: Fezzani Serbaji, S.; Chemmam-A, B.; Ben Salem, M.
Le chinchard à queue jaune est un Carangidae qui fait l’objet d’une exploitation par les différents types de pêche le long des côtes tunisiennes. Dans le présent travail on se propose d’étudier l’âge et la croissance sur la base de la distribution des fréquences de taille dans la région Nord de la Tunisie. La décomposition de ces fréquences de taille est réalisée suivant la méthode de Battacharya (1967). Deux périodes sont considérées, la première correspond à l’année 1998 et la seconde s’étale entre Novembre -1999 et Décembre -2000. Pour la première période, 6 classes d’âges ont pu être identifiées alors que pour la seconde cette valeur est de 7. Les équations de croissance linéaire annuelle suivant le modèle Von Bertalanffy (1938) ont été établies.

This paper combines agent-based modeling of structural change with agricultural policy analysis. Using the agent-based model AgriPoliS, we investigate the impact of a regime switch in agricultural policy on structural change under various framework conditions. Instead of first doing a sensitivity analysis to analyze the properties of our model and then examining the introduced policy in an isolated manner, we use a meta-modeling approach in combination with the statistical technique of Design of Experiments to systematically analyze the relationship between policy change and model assumptions regarding key determinants of structural change such as interest rates, managerial abilities, and technical change. As a result, we observe that the effects of...

Agglomeration Effects and Japanese Food Industry Investment in China: Evidence from the Cities
Provedor de dados: 31
Autores: Jin,   Shaosheng; Tokunaga,   Suminori; Akune,   Yuko; Kageyama,   Masahiro.
This paper uses the data from Chugoku Shinshutsu Kigyou Ichiran 2003-2004 (A View of Japanese Enterprises Investments in China 2003-2004) to study 1ocation choice of Japanese food industry investment in 231 Chinese cities from 1992 to 2001, paying a particular attention to agglomeration effects. A negative binominal model indicates that labor cost (WAGE) is the most important factor that deters Japanese food industry investment. Market size (GDP), raw material (MATER), port (PORT) and policy incentives (POLICY), however, have positive effects in Japanese food industry investment location choice in China. As for the three-tier agglomeration effects' test, the agglomeration effects of Japanese manufactures agglomeration (AG2) and Japanese food manufactures...

Aggressive behavior in the genus Gallus sp
Provedor de dados: 89
Autores: Queiroz,SA; Cromberg,VU.
The intensification of the production system in the poultry industry and the vertical integration of the poultry agribusiness have brought profound changes in the physical and social environment of domestic fowls in comparison to their ancestors and have modified the expression of aggression and submission. The present review has covered the studies focusing on the different aspects linked to aggressiveness in the genus Gallus. The evaluated studies have shown that aggressiveness and subordination are complex behavioral expressions that involve genetic differences between breeds, strains and individuals, and differences in the cerebral development during growth, in the hormonal metabolism, in the rearing conditions of individuals, including feed...

Aggressiveness between genetic groups I and II of isolates of Cercospora zeae-maydis
Provedor de dados: 63
Autores: Mathioni,Sandra Marisa; Carvalho,; Brunelli,Kátia Regiane; Beló,André; Camargo,Luis Eduardo Aranha.
For many years, the gray leaf spot disease (GLS) caused by the fungus Cercospora zeae-maydis Tehon &amp;amp; Daniels, was not considered an important pathogen of maize (Zea mays, L.) in Brazil. However, the recent adoption of agronomical practices such as no-tillage and cultivation under central pivot irrigation systems increased the incidence and severity to the extent that GLS is now one of the most important diseases of maize. Isolates of C. zeae-maydis can be distinguished by two genetic groups (I and II) based on AFLP markers and on polymorphisms of the ITS and 5.8S rDNA regions. Until now, however, the biological implications of this distinction remain unclear. This study investigated whether isolates from the two genetic groups differ in...

Agicultural development and trade liberalization
Provedor de dados: 26
Autores: Rodriguez, R.
Agriculture represents in Brazil roughly one third of GDP; a quarter of employment and 42% of exports. During the last 15 years, the cultivated area increased with 24%, but production more than doubled. Much attention is given to innovation in new technologies, fertilizers and agrochemicals for enhancing productivity. Supply in the agribusiness sector is continuously increasing, and Brazil has become a major exporter of coffee, sugar, soybeans and meat to the EU, US and Asian markets. Even while there is still some room for expansion, it is recognized that most of future agricultural growth must come from productivity improvement. Open markets are in the benefit of their consumers, but countries are entitled to maintain some subsidies for environmental and...

Agonistic-like responses from the torus semicircularis dorsalis elicited by GABA A blockade in the weakly electric fish Gymnotus carapo
Provedor de dados: 56
Autores: Duarte,T.T.; Corrêa,S.A.L.; Santana,U.J.; Pereira,A.S.F.; Hoffmann,A.
Findings by our group have shown that the dorsolateral telencephalon of Gymnotus carapo sends efferents to the mesencephalic torus semicircularis dorsalis (TSd) and that presumably this connection is involved in the changes in electric organ discharge (EOD) and in skeletomotor responses observed following microinjections of GABA A antagonist bicuculline into this telencephalic region. Other studies have implicated the TSd or its mammalian homologue, the inferior colliculus, in defensive responses. In the present study, we explore the possible involvement of the TSd and of the GABA-ergic system in the modulation of the electric and skeletomotor displays. For this purpose, different doses of bicuculline (0.98, 0.49, 0.245, and 0.015 mM) and muscimol (15.35...

Agricultural Change and Population Growth: District-Level Evidence From India
Provedor de dados: 31
Autores: Witcover,   Julie; Vosti,   Stephen A.; Lipton,   Michael.
Green Revolution technologies were developed and promoted in the 1960s in response to alarm about impending famine in Asia. By boosting food supplies and fostering development, the technologies were expected to create "breathing space" for completing demographic transitions there. This paper uses District-level data from rural India on agricultural transformation (from 1961 to 1981) and on changes in human fertility (from 1971 to 1981) to examine whether they did so. In a reduced form model, female literacy and marriage rates emerged as strong fertility change determinants; effects varied by age cohort. Growth in real wages in rural areas, in part brought about by HYV technologies, accelerated fertility declines. With real wage growth effects of Green...

Agricultural Contracting Update:  Contracts in 2003
Provedor de dados: 31
Autores: MacDonald,   James M.; Korb,   Penelope J.
Marketing and production contracts covered 39 percent of the value of U.S. agricultural production in 2003, up from 36 percent in 2001 and a substantial increase over estimated values of 28 percent for 1991 and 11 percent in 1969. Large farms are far more likely to contract than small farms; in fact, contracts cover over half of the value of production from farms with at least $1 million in sales. Although use of both production and marketing contracts has grown over time, growth is more rapid for production contracts, which are largely used for livestock.

On the basis of the stochastic kernel approach, the paper verifies the agricultural convergence process from 1994-2003 across a sample of 170 EU-15 regions at Nuts2 level classified according to their initial competitive profile through the Kohonen Self-Organizing Maps technique. The results achieved have, first, underlined the complexity of the competitive scenario summarized in four different profiles: non competitive regions; strongly competitive and innovative regions; competitive regions with diversification and production sustainability; and strongly dependent on the CAP direct support. They affect in a different way convergence. The process seems to be determined by the specific factors at the basis of agricultural competitiveness within which...

AGRICULTURAL COOPERATIVE ENTERPRISE IN THE TRANSITION FROM SOCIALIST COLLECTIVE FARMING

Autores: Gardner,   Bruce L.; Lerman,   Zvi.
Cooperative enterprise has appeal as a means of filling gaps in the economic institutions of the rural sectors of the transition economies of Central and Eastern Europe and the former Soviet Union. But in addition to problems that have faced cooperatives in the West because of their inherent characteristics, the Soviet-era legacy created cultural burdens that cooperatives will have to overcome. A review of countries’ experiences since 1989 indicates some commonalities in attempts to create “new cooperatives,” but also instructive differences across countries. The evidence so far is unfavorable for cooperatives in agricultural production. In marketing and input supply the current situation is more promising.

Agricultural cooperatives and quality-enhancing R&amp;D in the agri-food system
Provedor de dados: 31
Autores: Drivas,   Kyriakos; Giannakas,   Konstantinos.
This paper develops a game - theoretic model of heterogeneous consumers to analyze the effect of cooperative involvement on quality- enhancing product innovation activity, the pricing of food products, and the welfare of the groups involved in the context of a mixed duopoly where an openmembership consumer co- op competes with an IOF. Analytical results show that the involvement of the member welfare- maximizing co- op in R&amp;D can be quality and welfare enhancing by increasing the arrival rate of product innovations and reducing the prices of food products. The effectiveness of the co- op is shown to depend on the nature of product differentiation and the relative quality of its products, the degree of consumer heterogeneity, and the size of innovation...

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.

Agricultural Economics: A Brief Intellectual History
Provedor de dados: 31
Autores: Runge,   C. Ford.
Agricultural economics arose in the late 19th century, combined the theory of the firm with marketing and organization theory, and developed throughout the 20th century largely as an empirical branch of general economics. The discipline was closely linked to empirical applications of mathematical statistics and made early and significant contributions to econometric methods. In the 1960’s and afterward, as agricultural sectors in the OECD countries contracted, agricultural economists were drawn to the development problems of poor countries, to the trade and macroeconomic policy implications of agriculture in richer countries, and to a variety of issues in production, consumption, environmental and resource economics.

In the course of economic development there is a general downward trend of agricultural employment. In the EU-15, agricultural employment decreased by  2.3% p.a. (measured in regular persons) and  3.0% p.a. (measured in annual working units) between 1995 and 2000. In some of the new EU Member States, employment in agriculture plummeted in the early 1990s, whereas in others it increased during the first years of transition and has served as a social buffer in times of economic hardship. The most important determinants of agricultural employment changes are labor saving technical progress, the macroeconomic environment, the farm structure, socio-economic characteristics of the farmer and agricultural support policies.

Agricultural Extension in Kenya: Practice and Policy Lessons
Provedor de dados: 31
Autores: Muyanga,   Milu; Jayne,   Thomas S.
A consensus exists that extension services, if functioning effectively, improve agricultural productivity through providing farmers with information that helps them to optimize their use of limited resources. Variations in management practices and husbandry skills among small farmers in Kenya are very great. Tremendous poverty-reducing benefits could be reaped by bringing the production costs of the most inefficient farmers to mean productivity levels. Achieving these gains in maize production efficiency will depend on many factors, but extension is likely to be among the most important. Therefore, the costs to the nation of having an underperforming extension service – in terms of smallholder productivity, incomes, and poverty reduction, and the ability...

Agricultural Growth and Economic Development: A View through the Globalization Lens

Autores: Pingali,   Prabhu L.
This paper re-visits the age old proposition that agriculture growth contributes to overall economic development, and asks whether the relationship still holds in an increasingly globalized world. There is overwhelming empirical support for the above proposition, indeed, it is hard to find exceptions, barring a few city states, where sustained economic development has not been preceded by robust agricultural growth. However, there are a large number of countries that have witnessed neither agricultural growth nor economic development. Even in countries where agricultural growth has been significant, dramatic inter-regional differences persist. This paper examines the factors that contribute to or constrain the process of agricultural transformation. Does...

Agricultural Growth and Poverty Reduction: The Case of Mexico
Provedor de dados: 31
Autores: Soloaga,   Isidro.
Poverty levels have been diminishing in Mexico since the late 90's, although several regions still show high levels of poverty, and they are extremely high in some rural areas. This paper have addressed the issue of the linkages between sectoral growth (urban/rural) and poverty levels. It was found that although both types of growth impacted negatively on poverty levels in Mexico, rural growth seems to have a higher power in improving consumption per capita of the poorest among the poor people. Moreover, the only inter-sector linkage found was the one that connects rural growth with urban poverty for those people above the food -poverty line but below the moderate poverty line. Exploring plausible channels, we have found that rural growth enhances equality...

Agricultural Market Access: A Moving Target in the WTO Negotiations?
Provedor de dados: 31
Autores: Brockmeier,   Martina; Pelikan,   Janine.
This paper analyses the economic effects of different magnitudes of tariff cuts, different tariff cutting formulas, the implications of tariff capping as well as different numbers and width of tariff bands in the market access pillar of the Doha Round agricultural negotiations. The simulations are conducted with an extended version of the GTAP model and an extended version of the GTAP data base (6.0) including bound and applied rates. The results reveal that the EU-27 experiences a negative change of its trade balance in the highly protected beef and sugar sectors. The relative increase of EU beef and sugar imports is mainly evoked by the magnitude of tariff cuts and, to a lesser extent, by the kind of formula used to implement the tariff cuts. In...

Agricultural Marketing and Agribusiness Supply Chain Issues in Developing Economies:  The Case of Fresh Produce in Papua New Guinea
Provedor de dados: 31
Autores: Martin,   Sandra; Jagadish,   Ayyamani.
Large quantities of fresh produce can be grown in the Highlands provinces of Papua New Guinea, and this produce is then marketed to a range of markets, including the coastal cities of Port Moresby and Lae. However, it is often argued that the marketing system performs poorly, and various reasons for this are cited. In this paper, the results of a study on the marketing of smallholder produce originating in the Highlands provinces and destined for a range of markets, including the coastal cities, are presented. A defensible supply chain framework is used to evaluate a range of marketing issues and to evaluate the performance of the marketing system. The results of the study are refreshingly positive. It was found that the marketing system was remarkably...

Agricultural markets in Benin and Malawi
Provedor de dados: 31
Autores: Fafchamps,   Marcel; Gabre-Madhin,   Eleni Z.
Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs.

Agricultural Policy as a Social Engineering Tool
Provedor de dados: 31
Autores: Tavernier,   Edmund M.; Onyango,   Benjamin M.
This study uses logistic regression to estimate survey data on social engineering policies in the agricultural sector.  The study finds that farm operators are unlikely to support a policy allowing countries to restrict trade to pursue domestic economic and social policy goals if the policies affect international trade.  In particular the findings suggest that farm operators with annual gross sales including government payments between $500,000 and $999,999 are 80 percent less likely to indicate such a preference.  Farm operators with advanced degrees, some college education and a high school diploma are also unlikely to indicate such a preference.  In contrast farm operators who receive no income from farming or ranching and farm operators who receive a...

In this paper we examine the linkages between four bodies of business-to-business relationship theory (transaction cost analysis, the resource-based theory of the firm (RBV), social network theory and theories of trust and cooperation) to the design and governance of agricultural cooperatives. Defining a cooperative broadly as any type of alliance formed by producers for their mutual benefit, we base the discussion on three types of cooperative; traditional, "new generation" and learning networks. Our main focus is on cooperatives as an alliance between members, but we also discuss alliances between cooperatives We find that there is a gap in the literature relating to the analysis of alliances with more than two members (such as cooperatives), so the...

Agricultural Production Clubs: Viability and Welfare Implications
Provedor de dados: 31
Autores: Langinier,   Corinne; Babcock,   Bruce A.
Consumers are in general less informed than producers about the quality of agricultural goods. To reduce he information gap, consumers can rely on standards (e.g., certification) that ensure quality and origin of the goods. These costly standards can be adopted by a group of producers of high-quality goods. We study the formation of such a group that we model as a club. We first investigate under what circumstances a club of a given size is desirable for producers, and for society. We then analyze the optimal size of the club when there exists a direct barrier to entry, and when there is no barrier.  We find that for intermediate values of certification costs, the industry and a club of a given size of certified producers have divergent incentives....

Agricultural Productivity Trends in India: Sustainability Issues
Provedor de dados: 31
Autores: Kumar,   Praduman; Mittal,   Surabhi.
The sustainability issue of the crop productivity is fast emerging. The post-Green Revolution phase is characterized by high input-use and decelerating total factor productivity growth (TFPG). The agricultural productivity attained during the 1980s has not been sustained during the 1990s and has posed a challenge for the researchers to shift the production function upward by improving the technology index. It calls for an examination of issues related to the trends in the agricultural productivity, particularly with reference to individual crops grown in the major states of India. Temporal and spatial variations of TFPG for major crops of India have also been examined.

Autores: Pinstrup-Andersen,   Per.
This paper is about the two-way causal relationships between the global food system and health and nutrition. It argues that the global food system begins and ends with health and that the prioritization and implementation of agricultural research and policy should consider health and nutrition effects. An integrated health and food policy approach is likely to be more effective in achieving both health and economic development goals that the current practice of separate sectorial policies. The paper identifies a large number of health and nutrition factors affecting and affected by the food system and suggests research and policies to enhance positive effects and reduce negative ones.

Agricultural Sciences in Upland Northern Vietnam: Situating Research in a Dynamic Environment
Provedor de dados: 31
Autores: Friedrichsen,   Rupert.
This paper aims to provide an introductory overview over the socio-cultural context of Northern Vietnam to agricultural researchers. The paper focuses on the interplay between Vietnam's lowlands and the uplands to specify what makes the Northern uplands a distinct region; as an object of empirical agricultural research and as a context of application of research results.  The paper reviews the developments of selected social institutions from pre-colonial times to the current era of "renovation". First, developments in Vietnam's legal and administrative structures are outlined. Second, education and higher education, particularly the agricultural  sciences, are discussed. The third and main part elaborates on social, political, and economic specifics of...

Agricultural situation report of Cyprus and the market and trade policies for fruit/vegetable and olive oil
Provedor de dados: 31
Autores: Markou,   Marinos; Kavazis,   Andreas.
During the last decade the Cypriot agricultural sector has been declining in terms of most indices in the economy, mainly due to the spiraling growth of tourism, as crucial investment outlays were diverted from agriculture to tourism; the most important factors of production being land and labor due to substantially higher yields accruing to both. The Domestic Resource Cost (DRC) revealed that the three products studied for the period 1997 to 2000, i.e. tomatoes, oranges and olive oil had a comparative advantage. However, the opening of the European market with EU accession led to the substantive undermining of competitiveness of agricultural products and to the reduction of the value of exports. It is believed that DRC ratios would be higher today that...

Agricultural subsidies in the United States and their effect on two annual Chilean crops: corn and wheat
Provedor de dados: 123
Autores: Osorio,José Díaz; Rojas,Roberto Jara.
The development strategies for Chile have been oriented toward a greater commercial openness. Chile and the United States signed a Free Trade Agreement (FTA) that has triggered controversies between producers directed to the internal market due to the production and export subsidies that this country carries out. This study analyzed the effect of subsidies granted by the United States to wheat (Tritricum aestivum) and corn (Zea mays) growers (Farm Bill 2002). For the study, Technical Standard sheet were drawn up, from which were determined the direct production costs and the gross margins. The variables used (market prices, subsidies, freight costs and tariffs) and determining the average variable costs allowed us to do a sensitivity analysis, thus...

Agricultural Trade Liberalization Under Doha: The Risks Facing African Countries
Provedor de dados: 31
Autores: Badiane,   Ousmane.
African countries tend to be affected by global agricultural policies in the same way as other economies but with much more severe economy-wide repercussions. Most African countries find themselves at the lower end of the economic growth process, which implies a much greater dependence of overall economic growth on domestic demand, agricultural incomes, and agricultural trade. They tend to be characterized by a higher degree of trade openness, increasing dependency on food imports, heavy reliance on agricultural exports for foreign exchange earnings, and lower absorption capacities of global market shocks. These features do not only make African economies more vulnerable to distortions and changes in global trading policies in the agricultural sector. They...

Agriculturally Related Environmental Issues in Free Trade Agreements
Provedor de dados: 31
Autores: Colyer,   Dale.
The consideration of environmental matters in trade liberalization agreements has become an issue since they were included in NAFTA and recognized Uruguay round agreement that created the WTO. Many WTO members, especially the less developed countries, remain opposed to including environmental issues in trade agreements. However, Canada, the U.S. and a few other countries now include environmental provisions in their bilateral and regional trade agreements; the U.S. is required to do so under its 2002 Trade Promotion Act (PL 107-210). Furthermore, the declaration establishing the Doha Round of multilateral negotiations recognizes a role, albeit a limited one, for the environment in negotiating the next multilateral trade liberalization agreement....

Agriculture and Co-operativism, a Persistent Duality: The Case of Denmark
Provedor de dados: 31
Autores: Jakobsen,   Gurli.
The paper argues that co-operativism in Danish agriculture represents both continuity and strong changes from the start of the movement as the economic branch of a comprehensive social and political movement to the large agro-industrial enterprises of today, and that co-operativism still is a necessary tool for both large scale production and for innovation within the agro-industrial sector. After a short description of the role of co-operative thinking and organising in the Danish context historically, the paper presents a statistical overview of the current position of co-operative societies in Danish agriculture on the background of the structural changes that have occurred in primary agriculture and agro-industry during the last generation and a half....

Agriculture in the Age of Globalization
Provedor de dados: 31
Autores: Romano,   Donato.
This paper aims at analyzing the asymmetries in the process of globalization and its differentiated outcomes on (i) developed and less developed countries, and (ii) on LDC agriculture. The consequences of these asymmetries are reflected in the dramatic changes in world agricultural trade – an unprecedented growth of agricultural trade in real terms and a dramatic change in its composition which is increasingly moving away from bulk commodities towards high-value, processed consumer-ready agricultural goods. The impacts of these changes on LDC agriculture have been quite differentiated, with most countries experiencing a worsening of their agricultural trade balance. This change of the LDC trade position is counterintuitive if we still think of agricultural...

Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration into the European Union and the world market. Reduced subsidies, increased environmental and food quality demands, as well as structural changes in the supply, processing and food retailing sector call for major structural adjustments and the improvement of farmers’ managerial abilities. Though such changes always carry significant threats to farms, they also offer new opportunities for the farms' entrepreneurial engagement. Upcoming changes in the agricultural...

Agriculture, Income Risks and Rural Poverty Dynamics: Strategies of Smallholder Producers in Kenya
Provedor de dados: 31
Autores: Kuyiah,   Joanne Wasswa; Obare,   Gideon A.; Herrero,   Mario; Waithaka,   Michael M.
Poverty in Kenya has been on the increase over the last decade. It is estimated that 56% of the total population live in absolute poverty. Most of the poor reside in rural areas where agriculture is the main livelihood activity. Majority of Kenya's farmers are smallholders. They account for 75% of the total agricultural output and about 70% of marketed agricultural produce. The fate of smallholder agriculture in this country is therefore central to poverty reduction. A collapse in output and incomes from smallholder agriculture is likely to have damaging welfare effects and retard pro-poor economic growth. Smallholders often operate in a risky environment, which affects the level and variability of household resource endowments and income. The importance...

Agri-environmental Policy in the European Union:  Who's in Charge?
Provedor de dados: 31
Autores: Baylis,   Katherine R.; 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.   One way to try and determine how much of these non-commodity payments are directed to externalities and how much is intended to distribute income to producers is to analyze the variation of the programs among the...

Agri-environmental Policy in the European Union:  Who's in Charge?
Provedor de dados: 31
Autores: Baylis,   Katherine R.; Peplow,   Stephen; Rausser,   Gordon C.; Simon,   Leo K.
European Union (EU) agri-environmental programmes (AEPs) represent a significant step in the region's efforts to decouple agricultural output from production and export subsidies. While AEPs comprise only a small share of EU agricultural support, they have two possible external impacts: 1) the composition of the EU's imports and exports may change as their producers become more market responsive; and 2) the WTO's Green Box (subsides considered minimally trade distorting and hence not disciplined) may become increasingly contentious. Our concern is with the drivers of AEPs in the EU and their implications for Canada.

The phytopathogenic bacteria Agrobacterium rhizogenes genetically transforms plants by transferring a portion of the resident Ri plasmid, the T-DNA to the plant. Plant species differ in their temporal competence for transformation. But various physical and chemical methods are found to enhance transformation frequency. Agrobacterium rhizogenes mediated transformation efficiency was assessed under the influence of sonication, calcium treatment, acetosyringone and macerating enzymes in suitable combinations in Nicotiana tabacum as a model system. Manual wounding resulted in 21% transformation frequency. Where as sonication resulted in 2.2 fold increase, followed by sonication with CaCl2 treatment resulted in 2.5 fold increase and sonication with...

Agroecology education and research programs are gaining prominence in universities. This emerging field provides an appropriate and convenient platform for bringing organic farming into academia. Agroecology deals with complex systems, uncertainty, and the future. Examples from organic farming and local food systems often provide valuable examples of applications of the principles of ecology in designing a sustainable agriculture. The agroecology MSc program in the NOVA network is a successful example of how organic farming can be brought into university programs, and how interdisciplinary education and research can tap into a regional faculty in agriculture.

Agro-food chains and networks for development: issues, approaches and strategies
Provedor de dados: 26
Autores: Ruben, R.; Slingerland, M.; Nijhoff, H.
Agro-food chains and networks play an increasingly important role in providing access to markets for producers in developing countries. Globalization of trade and integration of supply chains lead to new demands regarding food quality and safety. Analytical approaches for addressing the role of trade for development involve a mixture of disciplines that focus on issues of efficiency, organization and innovation as key dimensions of competitiveness. Smallholder participation in global supply chains is critically determined by three processes: market access, network governance and chain upgrading. Public and voluntary agencies may provide important contributions for reinforcing the supply-chain environment.

Agro-food chains and sustainable livelihood: a case study of cassava marketing in Nigeria
Provedor de dados: 26
Autores: Oyewole, O.B.; Phillip, B.
Cassava is a good example of problems that local producers encounter in developing agro-food chains aiming at added value and fair rewards for labour inputs. Low production at many small-scale farms lead to high transaction costs. Cassava spoils easily and is costly to transport in its raw form as it consists mainly of water. Therefore much processing takes place on-farm. Processing results in Gari, Lafun and Fufu products with longer shelf life than cassava roots. These products are consumed in the household or sold in the local market. Middlemen buy these products to sell them to urban or international consumers. The products can also serve as basis for further industrial processing but this option is under-exploited so far. It is a highly competitive...

Autores: Taamalli,Wael; Geuna,Filippo; Banfi,Riccardo; Bassi,Daniele; Daoud,Douja; Zarrouk,Mokhtar.
In this study, a total of 14 agronomic traits, five AFLP primer combinations and ten SSR loci were used to describe and to classify a group of Tunisian olive genotypes into groups based on molecular profiles and agronomic traits. The analysis of variance of the agronomical data revealed significant differences among accessions for all measured traits. The mean phenotypic dissimilarity (0.34 with a range of 0.08-0.6) was low in comparison to dissimilarity calculated using AFLP (0.50 with a range of 0.16-0.70) and SSR markers (0.76 with a range 0.35-0.94). The correlation between the agronomical dissimilarity matrix and the matrices of genetic dissimilarity based on SSR and AFLP markers was very weak: 0.156 (p = 0.05) and 0.185 (p = 0.05), respectively.

Provedor de dados: 21
Autores: Böhm, Herwart; Krause, Tanja; Haase, Thorsten; Haase, Norbert U.; Loges, Ralf; Heß, Jürgen.
In order to achieve the successful cultivation of potato raw material to be processed into French fries and crisps, the high quality standards set by the processing industry have to be fulfilled and high tuber yields attained. In a cooperative research project, different strategies for the cultivation of high quality potato raw material for processing were examined under the conditions of organic farming.   The choice of variety was found to be the most important agronomic instrument for the organic farmer to secure high tuber yields and quality. Varieties Agria and Marena can be recommended as they gave high tuber yields of the required size grade and also high French fry quality both at harvest and after storage. With regard to processing into crisps,...

Água disponível em um Latossolo Vermelho argiloso e murcha fisiológica de culturas
Provedor de dados: 91
Autores: Klein,Vilson A.; Reichert,José M.; Reinert,Dalvan J.
Para a determinação do volume de água retido no solo e disponível às plantas, é imprescindível quantificar o teor de água do solo (TAS) na capacidade de campo (CC) e no ponto de murcha permanente (PMP). O objetivo deste trabalho foi comparar os valores do TAS na CC e no PMP determinados por distintos métodos. Utilizaram-se amostras de um Latossolo Vermelho. A CC foi obtida no campo com o método do perfil instantâneo e, no laboratório, com funis de placa porosa. O PMP foi determinado, em laboratório, como sendo o teor de água residual retida no potencial matricial de -1,5 MPa, em câmara de Richards e com medidor de potencial de ponto de orvalho WP4 PotentiaMeter. Para murcha das plantas, o TAS foi significativamente menor no método fisiológico que o...

Água no solo e rendimento do trigo, soja e milho associados ao El Niño Oscilação Sul
Provedor de dados: 86
Autores: Alberto,Cleber Maus; Streck,Nereu Augusto; Heldwein,Arno Bernardo; Buriol,Galileo Adeli; Medeiros,Sandro Luis Petter.
O objetivo deste trabalho foi simular o conteúdo de água disponível no solo e o rendimento das culturas de trigo, soja e milho, em Santa Maria, RS, e associá-los ao fenômeno El Niño Oscilação Sul (ENOS). O período estudado foi de 1969 a 2003. A água disponível no solo e o rendimento das culturas foram calculados com modelos matemáticos disponíveis na literatura. A água disponível no solo foi representada pela fração de água transpirável no solo pelas plantas. Foi constatado que a menor disponibilidade hídrica no solo está associada a anos neutros, e a maior disponibilidade hídrica está relacionada a eventos do El Niño. Os anos de La Niña foram os mais favoráveis ao rendimento de grãos da cultura de trigo, enquanto os anos de El Niño foram os mais...

"Aids" do marandu tem raízes na umidade do solo.
Provedor de dados: 14
Autores: VALENTIM, J. F.
Quando gostam de um capim, os pecuaristas costumam lhe conferir falsa "universalidade", plantando-o até mesmo em regiões inadequadas a seu cultivo. Foi o que aconteceu com a Brachiaria brizantha cultivar Marandu, lançada pela Embrapa em 1984 e batizada popularmente de braquiarão. Produtiva, rústica e de fácil manejo, ela tornou-se uma das "coqueluches" da pecuária nas últimas décadas e hoje constitui verdadeira monocultura, ocupando cerca de 60 milhões de hectares no Centro-Oeste e Norte do País. Mas como qualquer outro capim, o Marandu possui suas limitações; aliás, uma especialmente importante: ela não tolera excesso de umidade.

Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options
Provedor de dados: 31
Autores: Shih,   Jhih-Shyang; Burtraw,   Dallas; Palmer,   Karen L.; Siikamaki,   Juha.
The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to...

Autores: Strukova,   Elena; Golub,   Alexander; Markandya,   Anil.
The paper presents estimation of the health losses from urban air pollution in Ukraine.  The methodology developed by US EPA and adjusted in Russia for Eastern European transition countries was applied for health risk assessment. PM2.5 was identified as the major source of human health risk, based on experience from the Russian studies. In the absence of reliable computed concentrations of PM2.5, the study was based on monitoring data of total suspended particle (TSP) emissions in Ukraine. Additional cases of mortality and morbidity were calculated based on reporting data on TSP concentration that was recalculated into PM2.5. Then the concentration–response function was applied to estimate individual risk. Next, individual risk was applied to the...

Autores: Claudet, Joachim.
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers.  It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Ajustamentos nas agroindústrias de biscoitos e massas alimentícias no Brasil, 1995 a 2001
Provedor de dados: 123
Autores: Ferreira Júnior,Sílvio; Gomes,Marília Fernandes Maciel.
Este trabalho objetivou avaliar os ajustamentos ocorridos nos segmentos de biscoitos e massas alimentícias no Brasil, no período de 1995 a 2001, utilizando-se o modelo Estrutura-Conduta-Desempenho, da teoria da Organização Industrial. Os resultados mostram que o novo ambiente competitivo, deflagrado pela desregulamentação setorial e pela abertura comercial, permitiu a intensificação da concorrência e restringiu o poder de mercado das maiores empresas. Os dois segmentos foram obrigados a seguir o processo de adequação às exigências do consumidor, como a melhoria da qualidade, o aumento da variedade e a redução nos preços dos produtos. Todo esse processo foi liderado pelas maiores empresas, que realizaram investimentos em tecnologia e em capacidade produtiva...

Ajuste do método de Priestley-Taylor às condições climáticas locais
Provedor de dados: 70
Autores: Villa Nova,Nilson A.; Pereira,André B.
A sustentabilidade da agricultura irrigada depende primariamente do manejo eficiente da irrigação, de modo a aumentar a produtividade primária de uma cultura em determinada localidade. A eficiência no uso de água pode ser melhorada pelo próprio esquema de irrigação adotado, sendo essencialmente governado pelas condições climáticas. O planejamento da irrigação e a tomada de decisão são funções do conhecimento da demanda evaporativa da atmosfera, sendo expressa pela demanda potencial (ETo). Em geral, quase todos os métodos de estimativa de ETo reportados na literatura referem-se a valores diários, incluindo-se nessa situação as perdas noturnas de evaporação, as quais serão expressivas apenas em alguns dias após a chuva ou irrigação.

Alberta's Water for Life Strategy: Some early indications of its acceptance by the irrigation industry in Southern Alberta
Provedor de dados: 31
Autores: Bjornlund,   Henning; Nicol,   Lorraine A.; Klein,   Kurt K.
Water is essential for sustainable agricultural development - for irrigation of crops, livestock watering, processing, and sustaining farm families. Agriculture uses 71 percent of all water diverted for consumptive use in Canada (Environment Canada, 2004), and is by far the greatest water consumer in Canada. In the absence of a Canadian national water strategy, Alberta has developed a long-term water management plan called the Water for Life Strategy. Its successful implementation will depend largely on the participation of irrigators. This study explores the reaction of irrigators to one of the strategy's main goals - a 30 percent increase in water use efficiency and productivity by 2015 over 2005 levels. The study reveals that irrigators vary...

Não há dúvidas de que as necessidades de óleos vegetais para a produção de energia (biodiesel) aumentarão muito nos próximos anos, tanto no Brasil como no mundo, uma vez que a proteção do meio ambiente é uma exigência inevitável, que não pode esperar mais, em especial no que tange à substituição do petróleo e seus derivados, que respondem por mais de 60% da emissão dos gases, sobretudo o dióxido de carbono, que promove o efeito estufa e cuja principal conseqüência é o aquecimento da atmosfera e incremento do nível do mar, devido ao degelo, principalmente das calotas polares. Uma das alternativas fitotécnicas para a produção de óleo com vistas à síntese de biodiesel e que tem sido evidenciado, é o pinhão manso, também conhecido por purgulina do inferno ou...

Provedor de dados: 97
Autores: JARAMILLO,EDUARDO; HUZ,ROSARIO DE LA; DUARTE,CRISTIAN; CONTRERAS,HERALDO.
Four Chilean sandy beaches were sampled during the summer of 2000, to study the role of stranded algal wrack deposits on the population abundances of three detritus feeder species of the macroinfauna that inhabit the upper shore levels of that beaches: the talitrid amphipod Orchestoidea tuberculata Nicolet, the tylid isopod Tylos spinulosus Dana and the tenebrionid insect Phalerisida maculata Kulzer. The beaches were Apolillado (ca. 29° S), Quidico (ca. 38° S), Guabún and Mar Brava (ca. 42° S). Replicated samples were collected with a plastic cylinder (25 cm in diameter) from algal wrack deposits including the sediments beneath the wrack and nearby bare sand areas. Samples were collected at two beach levels, one closer to the sea with fresh deposits and...

Autores: LAMAS, F. M.; STAUT, L. A.
Tradicionalmente, para o cultivo do algodoeiro, o solo é preparado utilizando-se vários implementos e operações. Os implementos mais utilizados para o preparo do solo são: grade pesada (uma vez), grade leve (duas a três vezes) e, em muitos casos, ainda é utilizada uma grade intermediária. Este sistema de manejo leva à degradação das propriedades físicas, químicas e biológicas do solo e, paulatinamente, diminui o potencial produtivo do mesmo

Allelopathic effects of Rumex obtusifolius leaf extracts against native grassland species
Provedor de dados: 21
Autores: Zaller, Johann G.
In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions. To test this hypothesis, in a series of laboratory and field experiments aqueous extracts of green R. obtusifolius leaves were sprayed on seeds of 14 herbaceous plant species (graminoids, non-leguminuous forbs and leguminuous forbs) commonly native to perennial grasslands and its effects on seed germination compared with those with tap water spraying. An allelopathic effect was defined as inhibitory influence of Rumex extracts on seed germination relative to tap water. Generally, results of the laboratory experiments...

Allocating Nutrient Load Reduction across a Watershed: Implications of Different Principles
Provedor de dados: 31
Autores: Feng,   Hongli; Jha,   Manoj K.; Gassman,   Philip W.
A watershed based model, the Soil and Water Assessment Tool (SWAT), along with transfer coefficients is used to assess alternative principles of allocating nutrient load reduction in the Raccoon River watershed in central Iowa. Four principles are examined for their cost-effectiveness and impacts on water quality: absolute equity, equity based on ability, critical area targeting, and geographic proximity. Based on SWAT simulation results, transfer coefficients are calculated for the effects of nitrogen application reduction. We find both critical area targeting and downstream focus (an example of geographic proximity) can be more expensive than equal allocation, a manifestation of absolute equity. Unless abatement costs are quite heterogeneous across the...

Allocating Vote: Biosecurity - Towards an "Economics-Based" Approach for Setting Priorities for the Importation of Risk Goods
Provedor de dados: 31
Autores: Ryan,   Michael.
The New Zealand government (through its agency the Ministry of Agriculture and Forestry, MAF) seeks to mitigate the potential negative impacts of importation through requiring commodities that may pose a risk to New Zealand's primary production systems, human health, indigenous flora, fauna or biodiversity to have an import health standard. Given, potential import opportunities exist in a wide variety of commodities from many different countries, the demand for import health standards far outweighs MAF's available resources to develop them. Therefore MAF must have a framework that prioritises which import health standards will be developed. This paper briefly presents the framework MAF is currently using to undertake the prioritisation of import health...

Allozymic variation and differentiation in the chilean blue mussel, Mytilus chilensis, along its natural distribution
Provedor de dados: 74
Autores: Toro,Jorge E.; Castro,Grace C.; Ojeda,Johana A.; Vergara,Ana M.
Genetic differentiation in the Chilean blue mussel Mytilus chilensis (Hupé 1854) was investigated based on the variation in the allozyme frequencies of Pgm, Gpi, Icd, Me, Gsr, Lap and Pep in eight samples collected along 1800 km from Arauco (VIII Region) to Punta Arenas (XII Region). Despite the large geographic separations, values of Neis unbiased genetic distance, D (0.004-0.048) and standardised genetic variation among populations, Fst (0.011-0.055) were small. The levels of gene flow (Nm = 8) found in this study prevent the effect of differentiation among populations by genetic drift. This findings indicate that its long-lived planktotrophic larvae provides this species with considerable dispersal ability throughout its range which is favoured by the...

Hemoglobinopathies are the most common monogenic disorders worldwide; however, they have never been systematically studied from a genetic perspective in Uruguay. In this study, we determined the frequencies of hemoglobin variants in Afro-Uruguayans. A sample of 52 healthy unrelated Afro-Uruguayans from the northern (N = 28) and southern (N = 24) regions of the country was analyzed. Eight individuals (15.4%) were heterozygous for -alpha3,7thalassemia; seven of them (29.2%) were originally from the southern region, whereas one of them (3.6%) was from the northern region; the differences between both regions were statistically significant (p = 0.016 +/-0.003). The only structural mutation detected was betaS, which is typical of African populations. Four...

Autores: Watanabe,M.J.; Thomassian,A.; Teixeira Neto,F.J.; Alves,A.L.G.; Hussni,C.A.; Nicoletti,J.L.M.
Avaliaram-se as alterações do pH, da P O2 e da P CO2 do sangue arterial e da concentração de lactato sangüíneo de 11 cavalos adultos da raça Árabe, submetidos a exercício progressivo em esteira de alta velocidade. Antes do exercício, no intervalo dos 15 segundos finais de cada mudança de velocidade e aos 1, 3 e 5 minutos após o término do exercício foram coletadas amostras de sangue arterial e venoso para a mensuração dos gases sangüíneos e da concentração de lactato. O exercício resultou em diminuição do pH, da pressão parcial de O2 (P O2) e da pressão parcial de CO2 (P CO2). A concentração de lactato sangüíneo elevou-se exponencialmente a partir da velocidade de 8,0m/s até os momentos após término do exercício.

Alterações em atributos do solo decorrentes da aplicação de nitrogênio e palha em sistema semeadura direta na cultura do milho
Provedor de dados: 65
Autores: Lange,Anderson; Carvalho,João Luis Nunes de; Damin,Virgínia; Cruz,José Carlos; Marques,João José.
Nos últimos anos, tem-se procurado elevar os teores de C orgânico do solo e, ao mesmo tempo, aumentar a produtividade das culturas. Neste contexto, o sistema semeadura direta (SSD) tem importante participação, principalmente na região dos Cerrados. Entretanto, para se alcançar altas produtividades, as gramíneas requerem a adição de doses elevadas de adubos nitrogenados. Este trabalho teve por objetivo avaliar as alterações no solo decorrentes da aplicação de palha e de N em solo cultivado com milho por 10 anos (1991-2001) em SSD. O experimento foi desenvolvido na Embrapa-Milho e Sorgo, em Sete Lagoas-MG, em um Latossolo Vermelho distrófico típico sob cerrado. Os tratamentos constaram da combinação de palha sobre o solo (0, 3, 6, 9 e 12Mg ha-1 de matéria...

As plantas lenhosas, de maneira geral, possuem alto teor de lignina, podendo alcançar valores entre 25 a 35% em relação a massa seca. Valores normalmente encontrados nas plantas arbóreas. Algumas plantas jovens ou de hábitos de crescimentos inferiores aos arbustivos possuem baixo teor de lignina, neste sentido, buscando superar os atuais níveis de lignificação, foram testados em plantas fatores exógenos de estimulação. Um sistema enzimático complexo é responsável pela formação biossintética dos precursores intermediários da lignina, entretanto as peroxidases são responsáveis pela fase determinante da polimerização na parede celular, cuja atividade foi pressupostamente modificada através da aplicação de cálcio e boro, visando aumentar a resistência da...

Autores: Colodro, Gilberto; UNICAMP; Espíndola, Carlos Roberto; UNICAMP.
A extração mineral e a retirada de espessas camadas de solo para obras diversas (áreas de empréstimos) costumam gerar superfícies de solos degradados, com fertilidade inferior à de um solo produtivo. O lodo de esgoto, por apresentar elevados teores de macronutrientes e de matéria orgânica, constitui uma alternativa na recuperação desses solos. Com a finalidade de se estudar os efeitos do lodo de esgoto na recuperação de um Latossolo Vermelho degradado, foi avaliada a sua fertilidade, como indicador de sua qualidade. O delineamento experimental foi definido como blocos casualizados, com 4 tratamentos e 4 repetições, sendo: testemunha, fertilizante mineral e doses de 30 e 60 Mg ha1 de lodo à base seca.

Alterações na rugosidade superficial do solo pelo preparo e pela chuva e sua relação com a erosão hídrica
Provedor de dados: 90
Autores: Castro,Luciana Gomes; Cogo,Neroli Pedro; Volk,Leandro Bocchi da Silva.
Apesar de efêmera, a rugosidade superficial no solo induzida por métodos de seu preparo é requerimento importante nos sistemas de manejo de caráter conservacionista. Isto se deve ao fato de que ela aumenta a retenção e a infiltração superficiais de água no solo, reduz a velocidade e o volume do escoamento superficial e aprisiona os sedimentos da erosão, diminuindo os danos causados pela erosão hídrica. Considerando tais aspectos, realizou-se esta pesquisa com o objetivo de avaliar as alterações ocorridas na rugosidade superficial do solo pelas ações do preparo e da chuva, na ausência e na presença de cobertura morta, em relação à erosão hídrica. O estudo foi realizado em campo, na EEA/UFRGS, em Eldorado do Sul (RS), em 1996 e 1997, aplicando-se chuva...

Altered calcium currents in cultured sensory neurons of normal and trisomy 16 mouse fetuses, an animal model for human trisomy 21 (Down Syndrome)
Provedor de dados: 48
Autores: CAVIEDES,PABLO; CAVIEDES,RAÚL; RAPOPORT,STANLEY I.
Down syndrome is determined by the presence of an extra copy of autosome 21 and is expressed by multiple abnormalities, with mental retardation being the most striking feature. The condition results in altered electrical membrane properties of fetal dorsal root ganglia (DRG) neurons, as in the trisomy 16 fetal mouse, an animal model of the human condition. Cultured trisomic DRG neurons from human and mouse fetuses present faster rates of depolarization and repolarization in the action potential compared to normal controls and a shorter spike duration. Also, trisomy 16 brain and spinal cord tissue exhibit reduced acetylcholine secretion. Therefore, we decided to study Ca2+ currents in cultured DRG neurons from trisomy 16 and age-matched control mice, using...

Alternative Soil Fertility Management Options in Malawi - An Economic Analysis
Provedor de dados: 31
Autores: Sauer,   Johannes; Tchale,   Hardwick.
In this paper, we analyze the factors that influence the productivity of maize among smallholder farmers, given that unfavourable output and input market conditions throughout the 1990s have compelled smallholder farmers into unsustainable agricultural intensification. We use farm-household survey data in order to compare the productivity of smallholder maize production under integrated (ISFM) and chemical-based soil fertility management using a normalized translog yield response model. The results indicate higher maize yield responses for integrated soil fertility management options after controlling for the intensity of fertilizer application, labour intensity, seed rate, land husbandry practices as well as selected policy factors. The estimated model is...

The aim of the investigation is the provision of home-grown high-protein feed for cattle, pigs and poultry. Field trials with special attention to mixed cropping of lupines with spring cereals and of other legumes for grain production as well as for ensiling as whole crop were carried out in 2004 at two sites in northern Germany: At Braunschweig (conventional farming) and at Trenthorst, close to the Baltic Sea (organic farming). At Braunschweig, with blue lupine varieties grain yields between 29 and 44 dt DM/ha were achieved by sole cropping. In mixed cropping with field peas and spring cereals blue lupines revealed poor competitiveness with yield rates just between 20% and 32% of total grain yield. The only exception was the mixed cropping with rye, were...

Autores: Mouillot, D; Spatharis, S; Reizopoulou, S; Laugier, Thierry; Sabetta, L; Basset, A; Chi, T.
1. Transitional waters, described as critical transition zones because of their position at terrestrial, freshwater and marine interfaces, provide essential goods and services to the biosphere including human populations. These ecotones face increasing human influence mainly due to population density increase in coastal areas.   2. Transitional water bodies have, to date, received little attention in the development of ecological status indicators, this is a critical deficiency when trying to meet the Water Framework Directive objective of all significant water bodies achieving good ecological status by the year 2015.   3. In order to assess changes in transitional water communities many taxonomic-based indicators have already been proposed but there are a...

[1] Extreme weather events such as tropical cyclones are difficult to observe with conventional means. Satellite-based observations provide essential measurements of key parameters governing tropical cyclones. They are critical for short-term forecasting. Radiometers onboard the Defense Meteorological Satellite Program satellite series, WindSat and Tropical Rainfall Measuring Mission satellites, scatterometers onboard the ERS, ADEOS, and QuikScat satellites offer unprecedented synoptic observations of surface wind and atmospheric liquid water content, revealing the storm structures with good accuracy. However, satellite estimates do not provide direct measurements of geophysical parameters and can suffer from limitations linked to the sensors...

America's Diverse Family Farms:  Structure and Finances
Provedor de dados: 31
Autores: Hoppe,   Robert A.; MacDonald,   James M.; Banker,   David E.
American farms vary widely in size and other characteristics, but farming is still an industry of family businesses. Ninety-eight percent of farms are family farms, and they account for 86 percent of farm production. Very small farms are growing in number, and small family farms continue to own most farmland. But production is shifting toward very large family farms. Because small-farm households receive most of their income from off-farm work, general economic policies—such as tax policy or economic development policy—can be as important to them as traditional farm policy.

Amidst peril and progress: conservation of diversity and patent law
Provedor de dados: 26
Autores: Koopman, J.
Medicinal and aromatic plants are biological, cultural and industrial resources. The diversity from which they stem is in peril, though. The manner in which they are patented and exploited by the bioindustry upon their modification is controversial. It disregards interests of countries and communities that provide them. This is affected by the global regulative framework, devised pursuant to the neo-liberal policies that steer globalization. Patent law is part of that framework. Reformulation of ethical principles, policies and laws should lead to integrative protection of ecological, cultural and commercial interests. The Convention on Biodiversity should do just that. Its implementation is hampered by conflicts with said framework, and particularly...

Amino acid and ureide transport in the xylem of symbiotic soybean plants during short-term flooding of the root system in the presence of different sources of nitrogen
Provedor de dados: 61
Autores: Thomas,André Luís; Sodek,Ladaslav.
The transport of organic N compounds to the shoot in the xylem sap of nodulated soybean plants was investigated in an attempt to better understand the changes in N metabolism under root hypoxia (first 5 days of flooding), with different sources of N in the medium. NO3- is beneficial for tolerance of plants to waterlogging, whereas other N sources such as NH4+ and NH4NO3, are not. Nevertheless, in the presence of NH4+ high levels of amino acids were transported in the xylem, consistent with its assimilation. Some increase in the transport of amino acids was also seen with NO3- nutrition during waterlogging, but not with N-free medium. Ureide transport in the xylem was severely reduced during waterlogging, consistent with impaired N2 fixation under these...

Amino acid content of soybean samples collected in different Brazilian states: harvest 2003/2004
Provedor de dados: 89
Autores: Goldflus,F; Ceccantini,M; Santos,W.
Soybean is the most important protein source in animal nutrition and is widely used in poultry diets. Several factors influence the concentration of amino acids present in soybean grains cultivated in Brazil, such as climatic changes, genetics, topography, and soil fertility. Many technologies of soybean processing are used in order to eliminate or inactivate both heat-labile and heat-stable anti-nutritional factors. During processing, soybean by-products with different nutritional values are also produced. Processing conditions may as well affect the coefficients of digestibility of nutrients that are present in soybean protein sources. Furthermore, positive and negative effects of the environment may be masked by changes in processing conditions. This...

Ammonia emissions from pig and cattle slurry in the field and utilization of slurry nitrogen in crop production
Provedor de dados: 21
Autores: Mattila, Pasi K.
Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in the field and N uptake by ley or cereals was studied. The effect of a mixture of slurry and peat on soil properties was also investigated. The aim of this study was to find ways to improve the utilization of manure N and reduce its release to the environment. Injection into the soil or incorporation by harrowing clearly reduced NH3 volatilization from slurry more than...

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry
Provedor de dados: 21
Autores: Mattila, Pasi K.
Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was volatilized as NH3 from peat manure and pig slurry within 8 h of surface application on clay loam soil according to JTI method. Incorporated manures showed even smaller N loss. The low volatilization was due to the adsorption of manure ammoniacal N by peat, and the infiltration of slurry into harrowed, moist clay soil. In another experiment, peat manure was applied on polypropylene fabric without soil contact. Within the first 3 days there was only 9% reduction in the ammoniacal N of peat manure, but the...

Amphotericin B-related nephrotoxicity in low-risk patients
Provedor de dados: 55
Autores: Berdichevski,Roberto Herz; Luis,Luciano Billodre; Crestana,Letícia; Manfro,Roberto Ceratti.
INTRODUCTION: Amphotericin B (AmphoB) is the drug of choice for treatment of severe fungal illnesses; however, it is very nephrotoxic. Modified (less toxic) amphotericins are very expensive. In low-risk patients, saline loading would be enough to prevent significant loss of renal function. MATERIAL AND METHODS: Patients with normal renal function and within the first 24 hours of treatment with AmphoB were prospectively enrolled in the study. Patients in intensive care units or who were using vasoactive drugs were excluded. Saline loads were infused before and after the AmphoB treatment. Blood and urine analyses were made at the beginning and at the end of the treatment. Serum creatinine was repeated 30 days after the end of the AmphoB treatment. RESULTS:...

An Accidental Oil Spill Along the Belgian Coast: Results from a CV Study
Provedor de dados: 31
Autores: Van Biervliet,   Karl; Le Roy,   Dirk; Nunes,   Paulo A.L.D.
This paper offers an economic assessment of the loss of non-use values resulting from different oil spill scenarios along the Belgian Coast. Estimation results show that if no oil spill prevention policy action is undertaken, a significant welfare loss may result. As a matter of fact, contingent valuation estimation results show such a welfare loss ranges from 120 million Euro to 606 million Euro, depending on the size and the frequency of the oil spill under consideration. Therefore, any investment program targeted at the prevention of oil spills, and its damage on the marine environment, can be clearly defended from a cost-benefit perspective as long as its cost is no higher than 120 million Euro.

An Alternative Model for Analyzing the Physician-Hospital Relationship in Rural Areas
Provedor de dados: 31
Autores: Fannin,   James Matthew; Barnes,   James N.
We introduce a modeling framework called Transaction Cost Economics to help decision makers in rural health care markets choose among alternative organizational relationships in order to more cost-effectively deliver healthcare services.  In particular, the hospital-physician relationship is analyzed and the transactional attributes, institutional environment, and market characteristics are identified as key variables influencing the organizational relationship between hospital and physician.  As asset specfic investments are made by either the hospital or physician, vertically integrated relationships are more likely to occur.  The degree of remoteness of rural areas is also considered to affect the impact of these asset-specific investments.

An alternative pathway for plant in vitro regeneration of chinaberry -tree Melia azedarach L. derived from the induction of somatic embryogenesis
Provedor de dados: 69
Autores: Sharry,Sandra; Cabrera Ponce,José Luis; Herrera Estrella,Luis; Rangel Cano,Rosa María; Lede,Silvia; Abedini,Walter.
A highly efficient somatic embryogenesis system and subsequent plant regeneration of chinaberry (Melia azedarach L.) was developed. Plants were regenerated from indirect somatic embryogenesis induction. Novel features of this improved protocol, include: a) Embryogenic callus induction with no addition of 2, 4-D in the culture media; b) Somatic embryos differentiation was achieved by using high concentration of cytokinins (BAP 10 mg/L) and adenine; c) 100% conversion of somatic embryos to plants was practically obtained and 100% of plants survived under greenhouse conditions; d) Addition of putrescine improved somatic embryos germination. The amount of somatic embryos produced by the pathway of indirect somatic embryogenesis was 447 per gram of fresh weight...

This study investigated the non-neutrality of genetic polymorphism in two alpha-amylase genes (AMYA and AMYB) in the oyster Crassostrea gigas. Bi-parental oyster families, bred to be polymorphic for markers in these genes, were monitored for growth and survival for 1 year under standard culture conditions in two French production sites. Within-family genotype frequencies indicated that the two amylase genes were closely linked (c. 1.7 cM). Within two of three families, significant differences in growth were observed between genotypes at one of the two production sites, suggesting that this polymorphism is not neutral and might be under selection because of its role in digestive function. Estimated daily yields were different between amylase genotypes,...

This paper uses Federal LandBank Data to examine loan characteristics and farm financial characteristics. Given that farm financial characteristics and loan interest rates can change, this paper examines if current farm financial characteristics can predict the current loan interest rate. In addition, this paper tests to see if farm profitability can be predicted using two debt financial characteristics. Results indicate that interest rates and profitability are not very predicatable based on current farm financials information once the loan progresses.

Growing consumer interest in functional foods and nutraceuticals has been seen as a significant business opportunity for the agri-food sector.  Many of the new firms in this sector are small and medium sized enterprises (SMEs).  These SMEs often face difficulties in obtaining financing for their functional food and nutraceutical innovation activities.  We develop and implement two models to show what factors affect a firm's decision to seek external financing and the level of financing obtained.  Firm size, being privately held and engaging in contractual arrangements, have negative impacts on the likelihood of a firm seeking external funding, while firms which are intensively involved in the functional food and nutraceutical sector, with greater prospects...

The U.S. export share in the world peanut market has decreased due to heavy competition.  In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR).  Based on these estimations, a scenario analysis was conducted.  The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks.  The effects of price changes on net trade are noticeable.  However, the world price does not significantly affect the Latin American peanut supply.  The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

The objective of this applied research project is to use Wisconsin county sales tax data to identify the strengths and weaknesses of selected retail and service sectors. Using “count” data on the number of businesses that report taxable sales we apply regression analysis to develop an estimate of the expected number of firms in the county. By comparing the observed and expected number of firms we can identify strengths and weaknesses. Through the regression analysis we can also identify which socioeconomic characteristics are associated with which types of retail and service firms. The method that we offer we refer to as Firm Count Analysis (FCA) and can be viewed as a complement to Trade Area Analysis (TAA) and the analysis of sales data.

The livelihood systems of farm households in coastal Orissa have been analysed based on a sample of 193 farmers. It is found that the incomes of these households were quite diversified. As against the general impression that crop income dominates household income, it is observed that the non-farm income has emerged important in the coastal Orissa. Rice, which has been traditionally the main source of income in this area, has slipped to the third position, next to remittances and income from non-farm activities. The income from non-farm works and rice has accounted for 71 per cent and 20 per cent of the total income, respectively. The non-farm sources have contributed more than 90 per cent towards income inequality. The source-wise income share has also...

This paper describes the relationship between supply-chain management practices and new product development over time in the North American confectionery manufacturing industry. Using data from a survey of new product development managers, results indicate that buyer involvement and supplier involvement do not have a statistically significant impact on development time. Outsourcing of activities, however, does significantly impact new product development time. Findings of this study have important implications for supply-chain management practices of the food-manufacturing industry.

An Analysis of the Role of Tile-Drained Farmland Under Alternative Nitrogen Abatement Policies
Provedor de dados: 31
Autores: Petrolia,   Daniel R.; Gowda,   Prasanna H.
Agricultural nitrogen is a major contributor to Gulf of Mexico hypoxia, and research has shown that agricultural subsurface tile drainage is a major carrier of nitrogen from croplands to streams and rivers. This study compares the results of abating nitrogen under a retired-land minimization policy with those of a new revenue-maximizing policy, paying particular attention to the role of tile-drained land. Findings reveal the retirement-minimizing policy resulted in more tile-drained land being retired and less being fertilizer-managed than was optimal under the net-return maximizing policy. Also, it led to a greater economic burden being shouldered by tile-drained land. Under both cases, tile drainage dominated the abatement process.

An analysis of trade related international regulations of genetically modified food and their effects on developing countries
Provedor de dados: 31
Autores: Gruere,   Guillaume P.
This paper reviews current trade-related regulations of genetically modified (GM) food and discusses their effects on developing countries. There is a large heterogeneity in current import approval and marketing policies of GM food worldwide. At the international level, the harmonization efforts are led by the Codex Alimentarius Commission, the Cartagena Protocol on Biosafety and the World Trade Organization. While internationally harmonized guidelines for safety approval have been finalized, we show that there is no clear consensus on labeling regulations for GM food, and there is an increasing risk of conflicts among international agreements. We analyze the GM food regulations of two large rich importers, Japan and the European Union (EU) and discuss...

An Application of Spatial Poisson Models to Manufacturing Investment Location Analysis
Provedor de dados: 31
Autores: Lambert,   Dayton M.; McNamara,   Kevin T.; Garrett,   Megan I.
The influence product markets, agglomeration, labor, infrastructure, and government fiscal attributes had on manufacturing investment flows in Indiana between 2000 and 2004 were estimated using Poisson regression, geographically weighted regression, and a spatial general linear model.  Counties with access to urbanization economies, product markets, available labor, a high-quality workforce, and transport infrastructure were more likely to attract manufacturing investment.  These effects were magnified to some extent when inter-county spatial effects were modeled.  The distributional assumptions of the spatial models are different, but both methods are useful for understanding the spatial context of the factors influencing manufacturing investment flows.

Autores: Thürig, Barbara; Binder, Andres; Boller, Thomas; Guyer, Urs; Jiménez, Sonia; Rentsch, Christina; Tamm, Lucius.
We have examined the effect of Pen, an aqueous extract of the dry mycelium of Penicillium chrysogenum, on plant–pathogen interactions. Pen controlled a broad range of pathogens on several crop plants under greenhouse and ﬁeld conditions. Pen protected grapevine from downy and powdery mildew (caused by Plasmopara viticola and Uncinula necator), tomato from early blight (caused by Phytophthora infestans), onion from downy mildew (Peronospora destructor) and apple trees from apple scab (caused by Venturia inaequalis) to a similar extent as fungicides such as copper and sulphur or well-known inducers such as benzothiadiazole or b-aminobutyric acid. Pen had no major direct fungicidal eﬀect and is thus supposed to protect plants by activating their defense...

An assessment of nitrogen fixation in 'organically managed' spring-sown lupins and leaching under a following winter cereal
Provedor de dados: 21
Autores: Joynes, A; Hatch, D; Stone, A.
Three spring-sown species of lupins (Bora, Prima and Wodjil) and peas were compared in terms of N fixation and subsequent leaching under a following winter cereal crop. Although peas out-yielded lupins (5.4 t compared with ca 3.5 t grain, respectively), the yellow lupin (Wodjil) fixed more N than peas (180 compared with 120 kg N ha-1) and all three lupins contained more protein (&gt; 30%) than the peas (22%). Wodjil was the most effective at suppressing weeds, carrying only 12% of the weed burden found in fallow plots, followed by peas (19%). Winter leaching amounted to &gt; 50 kg nitrate-N ha-1 from under the winter cereal, regardless of whether the previous treatment was a legume crop or was left fallow. There were no significant differences in leaching...

An Assessment of the Livestock Mandatory Reporting Act
Provedor de dados: 31
Autores: Ward,   Clement E.
Federal government funding for public price reporting began in 1914. Since then, most public market reporting for livestock and meat has relied on voluntary participation by market participants.  Populist support in 1999 led to passage of the Livestock Mandatory Reporting Act which replaced the decades old voluntary reporting system with a mandatory system for livestock and meat.  Questions were raised by policymakers and others in discussions of the Act's renewal as to effectiveness of the mandatory reporting system.  This paper draws from available information to assess the Act's effectiveness since its initial implementation.  Satisfaction or dissatisfaction with the Act depends on one's expectations for what the Act was to accomplish or problems the...

An autoregressive model with time-varying coefficients for wind fields
Provedor de dados: 5
Autores: Ailliot, Pierre; Monbet, Valérie; Prevosto, Marc.
In this article, an original Markov-switching autoregressive model is proposed to describe the space-time evolution of wind fields. At first, a non-observable process is introduced in order to model the motion of the meteorological structures. Then, conditionally to this process, the evolution of the wind fields is described using autoregressive models with time-varying coefficients. The proposed model is calibrated and validated on data ill the North Atlantic.

An Economic Analysis of a Dairy Anaerobic Digestion (A.D.) System: Will Dairy Producers Invest in A.D. Technology to Reduce Potential Litigation Suits?
Provedor de dados: 31
Autores: Davis,   Brandon L.
In many areas of the United States, dairy and livestock farmers are facing lawsuits due to a variety of externalities, such as odor and other forms of non-point source pollution, caused by Confined animal feeding operations (CAFO's). Complaints include: general illness, unpleasant odor, headaches, and property devaluation. However, state and national law requires all CAFO's to have some form of waste storage facility. These facilities, mainly lagoons, increase the potential of pollution and run-off into streams and other water sources. As a result, large producers are beginning to install anaerobic digestive (A.D.) systems, which are a new form of waste management practices that reduces negative environmental effects.      Therefore, the purpose of this...

An Economic Analysis of Bushfires Management Programs
Provedor de dados: 31
Autores: Ganewatta,   Gaminda; Grahlmann,   Linda; Handmer,   John.
Allocating scare resources for fire management strategies requires information on the extent of economic losses from bushfires and the efficiency of alternatives. Despite the severity of bushfires, there is no agreed approach in Australia for estimating economic losses from fires nor for evaluating the economic efficiency of alternative suppression strategies. The poster proposes approaches to assess the economic effects of bushfires on local and state economies and sets out models to evaluate the economic efficiency of two key bushfire management strategies: presuppression and suppression. The first model arises from questions concerning the value of pre-suppression (before the fire) fuel reduction activities, and the estimation of an economically optimal...

An Economic Analysis of Control of the Western Corn Rootworm Variant across Indiana
Provedor de dados: 31
Autores: van Mellor,   Thuy; Alexander,   Corinne E.; Bledsoe,   Larry; Krupke,   Christian.
A variant of the western corn rootworm (CRW) has adapted to the widely used cultural practice of crop rotation. This study analyzed the economic value of control options controlling the western CRW variant across Indiana. The options analyzed are soil insecticides, seed-applied insecticides, the recently commercialized genetically modified corn to resist CRW (CRW corn), or not controlling the western CRW variant. The results suggest that the economic value of CRW corn may exceed that of the alternative options for corn producers with high western CRW variant pressure, irrespective of producers'’ risk aversion levels and have the highest economic value for risk-averse producers in the moderate western CRW variant pressure region of Indiana.

Provedor de dados: 31
Autores: Bullinger,   Jared R.; DeVuyst,   Eric A.; Bauer,   Marc L.; Berg,   Paul T.; Larson,   Daniel M.
The use of genetic knowledge is widespread in crop production but is just recently being utilized in livestock production. This study investigates the economic value to feedlots of a polymorphism in the bovine leptin gene. Previous studies indicate that this polymorphism is associated with fat deposition. Since fed cattle are often priced on a grid that considers both yield and quality grades, fat deposition is an important factor in the value and profitability of fed cattle. Using data from 590 crossbred steers and heifers, we estimate growth curves for relevant biological traits, both with and without genotypic information. Using the resulting functions, we then simulate carcass traits to various days-on-feed and compute the associated profit under three...

An Economic Analysis of Quarantine:  The Economies of Australia's Ban on New Zealand Apple Imports
Provedor de dados: 31
Autores: Arthur,   Matthew.
The quarantine policy decision-making process in Australia is subject to the principles of the World Trade Organisation's SPS Agreement. It is primarily based on the risks and associated economic costs accruing to producers in the event of disease entry. The costs of a quarantine measure in terms of forgone trade benefits are not considered. The impact associated with this asymmetric approach is identified by demonstrating the gains to consumers which may arise through liberalised markets using a case study of the Australian apple industry. A partial equilibrium analysis is used to show the impacts of apple market liberalisation, which can be expected to yield gains to consumers which are greater than the economic costs to on producers.

An Economic Assessment of the Amenity Benefits Associated with Alternative Coastal Protection Options
Provedor de dados: 31
Autores: Christie,   Mike; Colman,   Oliver.
Current government guidelines for the appraisal of coastal defence projects in the UK do not require that non-market amenity benefits to be considered . However, a new option in coastal defence, namely multi-purpose reefs, provides an opportunity to integrate coastal defence with significant amenity provision. This paper reports the findings of a choice experiment study that evaluated the amenity benefits of four alternative coastal defence systems currently being considered for Borth in west Wales. The results indicate that traditional coastal defence options such as timber and rock groynes do not generate amenity benefits, while a multipurpose reef would generate significant benefits in terms of improvements in the visual appeal of the beach, safer...

Economics is an evolving and emerging field of study, so is the management of ecosystems. As such, this paper delineates the co-evolution of economic evaluation that reflects the various recognized ecosystem management approaches of anticipative, adaptive and capacitive ecosystem management. Each management approach is critiqued and from this theoretical analysis an emergent approach for the management of ecosystem is put forward, which accordingly suggests an alternative methodological approach for economic evaluations.

In this paper, we examine the existence of agglomeration effect on production in the Japanese food industry from 1985 to 2000 using plant-level 4-digit subclassification, panel dataset and new agglomeration index in Akune and Tokunaga (2005), and Tokunaga, Kageyama, and Akune (2005), based on Ellison and Glaeser (1997). This is an improvement on the the conventional indices such as Location Quotient (LQ) or Location Gini Coefficient (L).When we apply a flexible translog production function and cost share equation as suggested by Kim (1992), we find that around 2% of positive agglomeration effect exists in absence of any restriction on homotheticity in the the case of employment based agglomeration (Gamma EG ).

This paper presents an empirical model of optimal budget allocation for import inspection of imported commodities. In this model, the budget constrained inspecting Agency wants to minimize the expected pest costs related to import trade pathways. The model is applied to the problem of budget allocation for inspection of chrysanthemum cuttings imported to the Netherlands. The numerical results imply that under a budget constraint, resources should be first allocated for inspection of pathways with the greatest expected pest costs. Pathways with lower expected pest costs should receive less or no resources. The inspecting Agency has to trade off risks between inspected and non-inspected pathways.

Current scientific management objectives for ICES roundfish stocks are to ensure conservation of the biological resource and do not explicitly consider economic or social objectives. For example, there are currently no objectives to maximize the sustainable yield or to reduce variability in total allowable catches (TACs). This is despite the fact that the current system can result in wide annual fluctuations in TAC, limiting the ability of the fishing industry to plan for the future. Therefore, this study evaluated management strategies that stabilized catches by setting bounds on the interannual variability in TACs. An integrated modelling framework was used, which simulated both the real and observed systems and the interactions between system...

Abstract - In our research we have evaluated a series of soil indicators to determine the correlation between individual soil properties in organic farming. Regression analysis has proven that the biological activity of the soil on organically farmed areas (grasslands) as expressed by respiration is mainly influenced by the bulk density, moisture, porosity, humus content, the proportion of cation exchange capacity and total nitrogen content. The multiple regressions have proven the important dependency of basal respiration to the moisture, bulk density and total nitrogen. The supply of organic matter to the soil environment, thus greatly influences the studied soil biological activity. Similar dependences were visible in the results of both conventional...

An estimated 58.3% of US households own pets (AVMA, 2002), and most people consume livestock products in the form of meat, dairy products, wool, or leather.  The health and well being of all these animals depend heavily on relationships with veterinarians.  Veterinarians also contribute to public health through the FDA, CDC, USDA, and numerous other government agencies at the federal, state, and local levels.  Issues of primary concern include food safety, biosecurity, and the numerous emerging (and re-emerging) infectious diseases that are zoonotic in nature.  Finally, veterinarians have an additional impact through their research contributions.  Virtually...

An Experimental Exploration of a Voluntary Mechanism to Reduce Nonpoint Source Water Pollution with a Background Threat of Regulation
Provedor de dados: 31
Autores: Suter,   Jordan F.; Vossler,   Christian A.; Poe,   Gregory L.; Schulze,   William D.; Segerson,   Kathleen.
In this paper we build on a voluntary mechanism introduced by Segerson and Wu (2006) that uses the threat of an ambient tax to induce nonpoint source polluters to reduce emissions.  In addition to reviewing Segerson and Wu's policy, we propose a new voluntary/threat policy that offers some theoretical advantages over that put forward by Segerson and Wu.  We then test various forms of voluntary/threat policies in the experimental economics laboratory and compare the outcomes to a policy that administers strictly a per unit ambient tax.

An Experimental Investigation of Consumer Willingness to Pay for Non-GM Foods When an Organic Option Is Present
Provedor de dados: 31
Autores: Bernard,   John C.; Zhang,   Chao; Gifford,   Katie.
This research compared bids that consumers placed on non genetically modified (GM), organic, and conventional versions of food products in order to determine if the organic market well serves those seeking to avoid GM foods. Auction  experiments using potato chips, tortilla chips, and milk chocolate were conducted with 79 subjects. Bids were modeled as a function of consumer demographics using a heteroskedastic tobit regression model. Results with the non-GM attribute nested into the organic characteristic showed that the latter's marginal effects were insignificant. This suggested the potential to further develop non-GM products for consumers not willing to pay extra for the remaining organic attributes.

An exploration of language for biodiversity and regeneration in Australian agriculture
Provedor de dados: 31
Autores: Scott,   Pennie; Watson,   Geoff K.
The language of words is the most commonly used tool in person to person communication and this in turn, profoundly reflects and creates an individual’s belief systems and behaviours. In the arena of sustainable production systems for food and fibre and the ‘management’ of natural resources, there is a plethora of information provided by organisations dedicated to researching and communicating new land use methods for farmers to implement. However to date, the uptake of new methods has been frustratingly low resulting in the on-going degradation of Australia’s fragile landscapes while exploitative farming practices continue. A key issue is whether the language of current policies is appropriate to influence the belief systems of decision makers in...

CORPOICA and IFPRI implemented a research project in Ventaquemada, Colombia. The project’s goal was to asses the benefits of Integrated Pest Management (IPM) practices and the potential of Genetically Modified insect resistant (Bt) potatoes to manage damage caused by the Guatemalan Tuber Moth (Tecia solanivora Povolny). The Guatemalan Tuber Moth is particularly destructive because field spraying on the adult stage is ineffective and there exists damage specificity to the tubers. Excessive pesticide sprays have resulted in resistance to several insecticides. Insect resistant (Bt) potatoes has been shown an effective means to control other members of the Tuber Moth complex. Thus a Bt potato may play a role in managing Tecia in Colombia. This is an ex ante...

An Exploratory Assessment of the Economic Impact of Forage Options for Beef Production on Smallholder Farms in the Red Soils Region of China
Provedor de dados: 31
Autores: MacLeod,   Neil D.; Wen,   Shilin; Hu,   Mingwen.
The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and...

An extract of Penicillium chrysogenum elicits early defense-related responses and induces resistance in Arabidopsis thaliana independently of known signalling pathways
Provedor de dados: 21
Autores: Thürig, Barbara; Felix, Georg; Binder, Andreas; Boller, Thomas; Tamm, Lucius.
An aqueous extract of the mycelium of Penicillium chrysogenum (further called ‘Pen’ induced early defense-related responses such as an extracellular alkalinisation in cell cultures and ethylene production in leaf slices of numerous mono- and dicotyledon plant species, including Arabidopsis thaliana, tomato, tobacco and rice. The Pen-elicitor was sensitive to protease digestion but insensitive to other enzymes, suggesting that the elicitor-active region is a protein or a peptide. Reversed phase, ion exchange and size exclusion chromatography revealed that the Penelicitor is heterogeneous. This prevented further identification of the elicitor. Pen protected A. thaliana from a broad range of pathogens, including an oomycete (Hyaloperonospora parasitica), two...

Over the last decades, the incidence of ultraviolet B (UVB)-related skin problems has been increasing. Damages induced by UVB radiation are related to mutations that occur as a result of direct DNA damage and/or the production of reactive oxygen species. We investigated the anti-oxidant effects of a Polygonum multiflorum thumb extract against skin damage induced by UVB irradiation. Female SKH-1 hairless mice were divided into three groups: control (N = 7), distilled water- (N = 10), and P. multiflorum extract-treated (PM, N = 10) groups. The PM (10 g) was extracted with 100 mL distilled water, cryo-dried and 9.8 g was obtained. The animals received a topical application of 500 µL distilled water or PM extract (1, 2, 4, 8, and 16%, w/v, dissolved in...

An illustrated key to male Actinote from Southeastern Brazil (Lepidoptera, Nymphalidae)
Provedor de dados: 49
Autores: Francini,Ronaldo Bastos; Penz,Carla M.
In certain times of the year, Actinote butterflies can be vastly abundant in Southeastern Brazil, thus representing conspicuous denizens of our fauna. Their wing coloration allows for the recognition of five major patterns, which probably resulted from mimicry. Furthermore, examination of series of field-collected and reared specimens clearly demonstrates a high intra-specific variation in wing color pattern. In concert, inter-specific resemblance (mimicry) and intra-specific variation make it difficult to discriminate Actinote species from each other. This key aims at providing a tool for identification of male Actinote. To that effect, we provide diagnostic characters and illustrations of wings and male genitalia for 22 species. We hope that the clear...

Provedor de dados: 55
Autores: Basano,S.A.; Bianco,A.; Taylor,W.R..J; Olliaro,P.; Camargo,L.M.A.
Drug-resistant Plasmodium falciparum is undermining malaria control efforts worldwide. In Brazil, mefloquine (MQ) at a dose of 15 mg/kg body weight is used to treat P. falciparum. At this dose, MQ resistance developed rapidly in Thailand. Use of a higher MQ dose may retard the development of resistance. We treated 50 patients aged one to 67 years who had acute, uncomplicated P falciparum malaria using MQ 25 mg/kg. There were no serious adverse events. Two patients complained of dizziness and insomnia. Assessing evaluable patients, the day 42 cure rate was 40/42 [95.2% (95% confidence interval 83.8 to 99.4%)]. Mefloquine was efficacious and well tolerated in this small cohort from the state of Rôndonia.

Autores: Axelsen, J.; Bruus-Pedersen, M.; Larsen, T.; Krogh, P.H.
Soil fauna diversity, as well as total mite and springtail numbers was correlated with soil type, tillage intensity and fertiliser use as well as crop and grazing history and duration of the current state of the field. 430 samples taken in 2002 on a wide range of organically farmed fields also showed that soil type interacted with crop type and grazing intensity. A higher number of mites and springtails were found in crops that included clover, almost independently of soil type. Higher numbers of mites were found at high grazing intensity compared to low grazing intensity on the same soil type.   In 2003, microarthropods were collected in spring, summer and autumn in Southern Jutland, Mid-Jutland and Sealand. In each region both cereal and vegetable fields...

The process of developing and successfully achieving endorsement of a strategic plan formulated for the Australian Venison Industry is presented in this paper, the first in a series of four papers on this theme. The endorsed strategic plan recommends that the industry should establish market focussed alliances with the aim of delivering a specified product to an identified target market. It also proposes generic industry policies and initiatives and suggests a stronger commercial focus for the RIRDC research model. The development process of the strategic plan relied on the integration of both analytical and relationship methodologies. This paper will detail the rationale underpinning this integrated approach together with its application to developing a...

An Innovative Approach for Modeling Crop Yield Response to Fertilizer Nutrients
Provedor de dados: 31
Autores: Upadhyay,   Bharat Mani; Smith,   Elwin G.; Favret,   M. Lucila.
Fertilizer recommendations seldom account for agro-climatic conditions, which are important factors that determine the response to fertilizer and the optimal rate of fertilizer. The nitrogen fertilizer response to open pollinated and hybrid canola types will also impact optimal nitrogen rates. This study used quantile regression to model canola yield response to nitrogen fertilizer. Quantile regression can apply different weights to the residuals, facilitating a response estimation where the agro-climatic conditions are not limiting and the yield response is due to the variable of interest. The economically optimal levels of fertilizers were calculated using the proposed and the conventional least squares procedures of the two canola types in western...

This article presents an integrated consumer acceptance and supply chain risk analysis of genetic modification in livestock production chains. In general, results provide insight into feasibility of certain GM applications to be incorporated into pork chain. Overall, livestock producers can expect a cost reduction. Moreover, with the heterogeneous nature of consumer preferences there are some segments that wholly respond on the integration of different GM applications in the chain. However, in some cases, it is difficult to say whether the chain can respond to consumers'’ requirements.

An Interactive Decision Model Integrating Broiler Production and Processing Responsiveness to Consumer and Producer Prices
Provedor de dados: 31
Autores: Costa,   Ecio de Farias; Houston,   Jack E.
In the vertically integrated poultry industry, profit maximization for broiler integrators must incorporate feed formulation, broiler production, and broiler processing operations to determine optimally sized birds for the most profitable market segments. Here, substituting cottonseed meal (CSM) for soybean meal (SBM) in broiler feed is evaluated under changing input and product market conditions, where there are two processing options – whole carcass vs. cut-up parts. For the prices analyzed, CSM-fed broilers earn higher profits for whole carcass processing, while SBM-fed broilers earn higher returns for cut-up parts processing. Optimal protein levels used in the feed processes exceed currently recommended levels.

The probability that buyers are deceived with regard to the quality or safety of purchased products (moral hazard) increases with the profits which suppliers can earn through opportunistic behaviour. It decreases with the probability and level of losses that result from disclosure of malpractice. It also decreases with protective factors rooted in the suppliers' social contexts - such as values, emotional bonds etc. - that shield them from yielding to economic temptations. This paper describes how a systematic analysis of economic incentives and social context factors can be provided through an interdisciplinary approach which combines the analytical powers of microeconomics (game theory) and criminology (control theories).

An inter-sectoral economic model for optimal sustainable mangrove use in the small island economy of Tonga
Provedor de dados: 31
Autores: Rohorua,   Halahingano; Lim,   Steven.
The dependency of small island economies on natural resources coupled with the pubic nature of these resources means that sustainability is a topical issue especially when development projects offer opportunities for "better living" for communities. For a mangrove dependent community of Pangaimotu in Vavau in Tonga tourism development offers better income from employment opportunities. Yet reclaiming mangrove areas for tourism development is likely to impact on fisheries resources that have traditionally been the main form of livelihood for the community. It is argued that for small island communities, whenever development activities ignore the critical role of mangroves on fisheries resources, the wider implications to the community are also overlooked....

Why Australian wool producers remained in the business despite the hardship they have experienced for much of the 1990s from low prices of wool? This question was raised frequently by research scientists and policymakers of the wool industry. A recent exploratory study gives a notion that Australian wool production could be a 'lifestyle' choice and/or a choice other than economic reasons. To validate this notion this paper investigates the factors that drive and motivate the Western Australian wool producers, as identified in the exploratory study, by applying a Structural Equation Modelling approach. An innovative mixed research method is adopted in this study. Telephone survey is conducted among a random selection of 290 wool producers in WA. The results...

Autores: Sørensen, Jørn Nygaard; Thorup-Kristensen, Kristian.
Tomato plants were grown in open beds, confined beds, or combined beds with compost based on clover grass hay, deep litter and peat. Plants grown in the confined and the combined beds produced the earliest tomatoes. During the first five weeks of harvest, approximately 18% of the fruits produced in confined beds developed blossom end rot. This disorder was hardly developed in the other growing systems. After five weeks of harvest, these differences in fruit production were unchanged or even increased. Plants grown in the confined beds produced significantly less fruit load compared with the other bed types, especially in 2003. Application of supplemental fertilizer did not significantly increase the fruit production in any year.

The effect of negative information on consumer product evaluations has been studied heavily in the context purchase intentions and other preference-related measures. In this study, we examine the context (negative health hazard information on meat commodities), direction (positive and negative), and intensity (low and high) of information on consumer choice processes. We draw from the literature on Bayesian updating, choice processes and heuristics, as well as cognitive and information processing to propose a set of hypotheses and empirically test them using survey data. Our results indicate that under low intensity, information consumers tend to employ a non-compensatory type choice process with the health aspects of the product being nonsalient. In the...

An outer-ramp brachiopod assemblage from the uppermost San Juan Formation (middle Arenig), northern Argentine Precordillera: paleoecologic and biogeographic implications
Provedor de dados: 41
Autores: Benedetto,Juan L.; Cech,Norma.
Rhynchonelliformean brachiopods from the Arenig outer-ramp carbonate facies exposed at the Guandacol-Gualcamayo depocenter (northern Precordillera basin) include the new species Orthidium guandacolensis , Taffia ( Chaloupskia ) minima and Leptella ( Petroria ) ventrocristata . Associated taxa are Archaeorthis sp., Ffynnonia sp. and Tritoechia ( Tritoechia ) sp. The overlying basinal black shales (Gualcamayo Formation) have yielded Pelonomia ? sp. On the basis of the age of Ffynnonia occurrences in western Gondwana it is suggested that this genus migrated from the Famatina back-arc basin to the open platform waters of the northern Precordillera basin and then to shallower water settings of the carbonate ramp located to the south (in present coordinates)....

An Outlook for the Biofuels Industry in the Southern United States
Provedor de dados: 31
Autores: Crooks,   Anthony C.; Dunn,   John R.
Two seemingly unrelated topics are discussed- an outlook for biofuels in the southern United States, along with an overview of the important role that information technology is playing in the fuel ethanol industry.  The outlook discussion is limited to issues involving the two principal biofuels, fuel ethanol and biodiesel, and their respective feed stocks, corn and soybean oil.  The two topics are linked with a description of how information technology (IT) has enabled the development of the fuel ethanol franchise and a discussion of how IT is changing the very nature of biofuel operations.

The study finds strong correlations between natural products business performance and the impeding factors. The impediments include access to finance and markets, lack of herbal market information especially relating to external markets. Additionally, there is lack of processing capacity, while at the same time most if not all the natural products business operators lack technical training relating to product handling. However, there is big potential for success, the top ten traded natural products, may be exploited initially, both domestically and for export market, given range of perceived use. The constraints identified require concerted efforts from all stakeholders to recognize the importance of this sub-sector in providing opportunities to successful...

An overview of proximate factors affecting the nesting behavior of solitary wasps and bees (Hymenoptera: Aculeata) in preexisting cavities in wood
Provedor de dados: 82
Autores: Morato,Elder F.; Martins,Rogério P.
Guilds of Aculeate solitary wasps and bees that nest in preexisting cavities in wood are important components of terrestrial ecosystems because they engage in several ecological interactions (e.g. predation and pollination) with other species of plants and animals. Spatial and temporal variations in richness and abundance of solitary wasps and bees can be related to changes in environmental structure and in the diversity of other groups of organisms. The nesting period of these Aculeata is their most critical life cycle stage. Females of solitary wasp and bee species invest relatively more time constructing and provisioning their nests than do females of social species. Differently from species that nest in the soil or construct exposed nests, the main...

Autores: Lunz,W.; Oliveira,E.C.; Neves,M.T.D.; Fontes,E.P.B.; Dias,C.M.G.C.; Natali,A.J.
The present study investigated the effects of exercise and anabolic-androgenic steroids on cardiac HSP72 expression. Male Wistar rats were divided into experimental groups: nandrolone exercise (NE, N = 6), control exercise (CE, N = 6), nandrolone sedentary (NS, N = 6), and control sedentary (CS, N = 6). Animals in the NE and NS groups received a weekly intramuscular injection (6.5 mg/kg of body weight) of nandrolone decanoate, while those in the CS and CE groups received mineral oil as vehicle. Animals in the NE and CE groups were submitted to a progressive running program on a treadmill, for 8 weeks. Fragments of the left ventricle were collected at sacrifice and the relative immunoblot contents of HSP72 were determined. Heart weight to body weight ratio...

Anaerobic digestion of Ulva sp 3. liquefaction juices extraction by pressing and a technico-economic budget
Provedor de dados: 5
Autores: Morand, Berenice; Briand, X; Charlier, R.
In many countries, the algae of "green tides" are harvested in the fight against pollution. Ulva often represents the main component of the tide, and intensive research has been conducted on the possibility to use the algae as a methanisation substrate. However, methanisation is hampered by various practical obstacles, which requires a compromise between productivity and biological yield.   The process described here calls upon a pre-digestion phase of Ulva which, besides the economy of time and volume of the digestion, makes it possible to obtain a biogas of good quality. The methanisation substrate is the hydrolysis juice collected by draining, followed by pressing. The cake resulting from the pressing process can be used as organic enriching or...

Análise cladística e biogeografia de Ochlerini (Heteroptera, Pentatomidae, Discocephalinae)
Provedor de dados: 76
Autores: Campos,Luiz A.; Grazia,Jocélia.
Neste trabalho foi realizada uma análise cladística, utilizando 63 caracteres, dos 30 gêneros da tribo Neotropical Ochlerini Rolston, no intuito de testar seu monofiletismo e estabelecer uma hipótese de parentesco. Janeirona Distant, 1911 (Pentatomini) e as tribos Discocephalini e Halyini foram incluídas no grupo-interno para testar seu relacionamento com Ochlerini; Marghita Ruckes, 1964 e Stictochilus Bergroth, 1918 (Pentatomini) foram utilizados como grupos-externos. Os cladogramas de consenso estrito obtidos indicam que Ochlerini e Discocephalinae são grupos monofiléticos, mas Pentatominae, Halyini+Ochlerini, Pentatomini+Ochlerini, Ochlerus Spinola, 1837, Stalius Rolston, 1992 e Alitocoris Sailer, 1950 são grupos merofiléticos.

Análise da produtividade de grãos de três cultivares de arroz de terras altas: características varietais e potenciais de produtividade.
Provedor de dados: 14
Autores: STONE, L. F.; GUIMARÃES, C. M.
Utilizaram-se dados de produtividade e de seus componentes, obtidos em experimentos conduzidos na Embrapa Arroz e Feijão, para comparar as características varietais e potenciais de produtividade das cultivares de arroz de terras altas Maravilha, Carisma e BRS Bonança. A produtividade foi decomposta em três componentes: número de panículas m-2 (NP), de grãos por panícula (NGP) e massa dos grãos (MG). O valor máximo de cada componente, sob condições locais, é definido pelos valores dos componentes antecedentes. Esses valores estabelecem o nível de competição pelos recursos a que um componente é submetido. A competição começa além de um valor crítico (L) de NP. Uma curva limite superior, formada por uma reta horizontal e uma hipérbole, foi definida para cada...

Análise da transição entre dias secos e chuvosos por meio da cadeia de Markov de terceira ordem
Provedor de dados: 86
Autores: Keller Filho,Thadeu; Zullo Junior,Jurandir; Lima,Paulo Roberto Schubnell de Rezende.
O objetivo deste trabalho foi verificar se as ocorrências de dias secos e chuvosos são condicionalmente dependentes da seqüência dos três dias secos e chuvosos anteriores, numa zona pluviometricamente homogênea, por meio da cadeia não-homogênea de Markov de terceira ordem. Os resultados mostraram que as probabilidades diárias de transição podem ser adequadamente estimadas, com base em dados agregados bimestralmente, seguidas de interpolação por meio de funções sinusoidais. Além disso, evidenciou-se que, naquela zona, as ocorrências diárias de chuva são condicionalmente dependentes da seqüência de dias secos e chuvosos nos três dias anteriores. A cadeia não-homogênea de Markov de terceira ordem é um importante instrumento para a análise da dependência entre...

Provedor de dados: 31
Autores: Lamounier,   Wagner Moura.
It was intended in this research to detect and to analyze the existence of conditional volatility in the time series of the prices of the spot market of the Brazilian coffee in the New York Board of Trade (NYBOT) in the period between January of 1946 and December of 2000. The results of the models of GARCH type, applied for the prices of the coffee, indicated that the conditional variance of the residues of the models possess unit roots and the same one will not present a behavior of reversion to its historical average with passing of the time, after a shock. This happens because, the coefficients of volatility persistence had been all bigger or next to one

Therefore, would be really important, and useful, to calculate the risk share of each player. Than, this article showed the risk amount absorbed by the players in the coffee market of Minas Gerais, based in the prices paid in the south of that state, the greatest region producer, trough two models of Value at Risk (VaR), the Normal Model and the Historic Simulation Model. The results shows a risk absorbed about 17,28%, with 95% of sure, and 24,60% with 99% of sure, both of them in a...

Análise do armazenamento de milho no Brasil em um mercado de economia aberta
Provedor de dados: 123
Autores: Guimarães,Vania Di Addario; Barros,Geraldo Sant'Ana de Camargo.
O estudo desenvolve um modelo dinâmico de expectativas racionais para analisar o mercado de milho no Brasil no final da década de 1990, no qual o governo intervém com uma política de subsídio ao produtor, através do Prêmio para Escoamento de Produto (PEP) e considerando ainda o comércio internacional. O modelo é estimado através de programação dinâmica estocástica. Os resultados mostram que a abertura do mercado transfere para o comércio exterior o papel de amortecedor de choques de oferta e demanda internos que, no caso de mercados fechados, é desempenhado pelos estoques entre anos safra. Os resultados sugerem que, dependendo dos valores relativos entre o preço mínimo e o preço de exportação, a política de subsídio pode levar o país à condição de...

Provedor de dados: 31
Autores: Machado,   Lenilma Vera Nunes; Amin,   Mario Miguel; Carvalho,   Fatima Marilia Andrade de; Santana,   Antonio Cordeiro de.
The study analyzes the behavior of the Brazilian’s beef exports, in natura, during the 1995 to 2003 period. It shows that the substantial increase in exports made the country one of the leading beef exporters and tries to identify the factors that contributed for this growth. The methodological procedures involve the application of the Constant-Market-Share model to identify the sources of growth of the exports through the world trade growth effect, origin of exports effect and competitive effect. The composition effect was not estimated given the fact that the model was applied to only one product. The results show that the competitive and structural effects gave a significant increase to the Brazilian’s exports. The study shows, also, that Brazil...

Análise do grau de restritividade de exigências técnicas às exportações brasileiras
Provedor de dados: 31
Autores: Faria,   Rosane Nunes de; Burnquist,   Heloisa Lee.
The objective of this investigation was to evaluate to what degree technical requirements restrict Brazilian exports, based on a survey applied to 77 firms. The variables represented six types of technical measures that are usually imposed upon exported products. To facilitate the interpretation of the results, factorial analysis was used to reduce the number of variables involved. This allowed the construction of two indicators of the degree of restrictiveness of the technical barriers focused by the study. These were an indicator of requirements of technical specification (ITS) and an indicator for information and label requirements (IIL). Descriptive statistics and paired t test showed that the firms surveyed considered the ITS more restrictive to their...

O presente artigo tem por objetivo verificar os impactos das mudanças no ambiente institucional, europeu e nacional, em virtude das exigências do consumidor europeu quanto à qualidade do produto, sobre o Sistema Agroindustrial Bovino nacional. Os resultados indicam que embora o aumento das exigências dos consumidores europeus tenha alterado o ambiente institucional do bloco, com conseqüentes alterações no ambiente institucional brasileiro, houve pouco impacto sobre a forma de governança das transações do SAG da carne bovina nacional. Na relação da indústria frigorífica exportadora com o fornecedor de boi, verificou-se que não há estabelecimentos de contratos nas transações, que pode ser explicado pela credibilidade entre as partes no que tange ao pagamento...

Análise matemática e biológica dos modelos de estimativa de perdas de rendimento na cultura devido à interferência de plantas daninhas
Provedor de dados: 87
Autores: Adati,C.; Oliveira,V.A.; Karam,D.
As plantas daninhas acarretam reduções no rendimento das culturas agrícolas. Os modelos matemáticos de estimativa de perda de rendimento na cultura devido à interferência dessas plantas podem ser instrumentos úteis à tomada de decisão de manejo. Se for possível prever as perdas de rendimento, será possível decidir se é viável ou não a aplicação de uma medida de controle. Há na literatura vários modelos matemáticos empíricos de regressão lineares, não-lineares e polinomiais usados para estimar as perdas de rendimento devido às plantas daninhas. O presente trabalho teve como objetivo apresentar uma análise dos modelos matemáticos presentes na literatura utilizados para estimar as perdas de rendimento que as plantas daninhas acarretam à cultura, considerando...

Provedor de dados: 86
Autores: Baretta,Dilmar; Mafra,Álvaro Luiz; Santos,Julio Cesar Pires; Amarante,Cassandro Vidal Talamini do; Bertol,Ildegardis.
O objetivo deste trabalho foi avaliar o efeito de sistemas de preparo e cultivo do solo sobre a diversidade de animais da fauna edáfica, por meio de técnicas de análise multivariada. Na análise canônica discriminante, os preparos conservacionistas com sucessão de culturas foram separados em relação aos tratamentos com rotação de culturas. Os grupos Acarina, Hymenoptera, Isopoda e Collembola, e o índice de Shannon (H) foram os atributos que mais contribuíram para separar os tratamentos. A análise de correspondência mostrou forte associação dos grupos Acarina e Hymenoptera com o tratamento semeadura direta com sucessão de culturas, e do grupo Collembola com o preparo convencional.

Análise multivariada da resistência do solo à penetração sob plantio direto
Provedor de dados: 65
Autores: Weirich Neto,Pedro Henrique; Borghi,Elaine; Sverzut,Claudio Bianor; Mantovani,Evandro Chartuni; Gomide,Reinaldo Lúcio; Newes,Walter Luiz de Castro.
Com vistas ao aumento da produção, optou-se, no Brasil, pelo acréscimo de área cultivada e pelo intenso uso da motomecanização, o que acarretou prejuízos aos solos agrícolas. Paralelamente, práticas conservacionistas têm sido adotadas, a exemplo do sistema plantio direto. Em ambos os casos, estudos do estado de compactação do solo se fazem necessários. Prática e controversa, a penetrometria é a metodologia mais utilizada para o dimensionamento desse parâmetro. Assim, realizou-se trabalho em um Latossolo Vermelho sob plantio direto visando a identificar a estratificação vertical da resistência do solo à penetração. Foram amostrados 40 pontos, em malha de 50mx50m. Em cada ponto, analisou-se o comportamento do solo em três posições: na linha de semeadura,...

Provedor de dados: 86
Autores: Amarante,Cassandro Vidal Talamini do; Chaves,Daniela Vieira; Ernani,Paulo Roberto.
O objetivo deste trabalho foi identificar atributos nutricionais, quantificados na polpa e na casca dos frutos, que melhor discriminam quanto à severidade de "bitter pit" em maçãs 'Gala'. Depois de quatro meses de armazenamento em atmosfera normal (0-1°C; 90-95% UR), os frutos foram separados em quatro lotes, de acordo com a severidade de incidência de "bitter pit": nula (nenhuma lesão por fruto), baixa (1-2 lesões por fruto), moderada (3-4 lesões por fruto) e alta (5-13 lesões por fruto). Foram determinados os teores de Ca, Mg, K e N na casca e na polpa em frutos individuais (doze frutos de cada lote). A análise univariada mostrou que os frutos com sintomas de "bitter pit" apresentaram menor teor de Ca na casca e na polpa, maior teor de K na casca e...

Análisis comparativo del gen P de Rinderpest Virus (RPV)
Provedor de dados: 78
Autores: Vagnozzi,A; Carrillo,C.
Rinderpest Virus (RPV) es el agente causal de una severa enfermedad del ganado doméstico. Es un virus envuelto, cuyo genoma RNA no segmentado, de cadena simple y negativa (-ssRNA), está organizado en seis genes no superpuestos. El gen P es el más complejo de dichos genes, codificando una proteína estructural (P) y dos no estructurales (C y V). La proteína P es esencial para la replicación viral y está involucrada en todos los aspectos del ciclo viral. En cambio, las proteínas C y V son consideradas no esenciales para la replicación, al menos in vitro. En este trabajo hemos secuenciado el gen P de 16 aislamientos diferentes de RPV, y realizado el análisis comparativo de las secuencias obtenidas, poniendo el énfasis en las regiones conservadas en relación a...

Análisis de la pesca del mero Epinephelus morio
Provedor de dados: 20
Autores: Giménez, E.
The red grouper fishery is in its decline phase presenting an average annual catch of 8191 t during the 1999 to 2003 period. Through these years Cuban fleet has reduced its fishing area toward the oriental region of the Campeche Bank while the artisanal fleet extended, increasing the overlap of sizes catched by the arisanal-industrial and artisanal-cuban fleets. The size composition of the catch shows that most of the fishes are captured before first maturation size. First catch age is 2 years, and complete fishery recruitment is at age 3 (age of first maturation), this being a factor against fishing sustainability and forcing adoption of management strategies. The natural mortality is calculated (M) for the each age in the fishery by the function Y =...

Autores: Brunel, Thomas.
Recruitment - the number of young fishes that integrate each year the exploitable stock¿ has a central importance for stock dynamics. The high temporal variability in recruitment is a result of the environmental influence on survival during early life stages. Understanding the determinism of the influence of environment on recruitment remains one of the most important question in fisheries ecology. The present work aimed at answering some general questions about the influence of environment on fish recruitment using a macroecological approach. The study focused on the exploited fish populations of the Northeastern Atlantic. The first chapter of the thesis makes a review of the different methods used to estimate recruitment, compares recruitment estimates...

Analyse des petits pelagiques, sardine et anchois, dans le golfe de Gascogne
Provedor de dados: 5
Autores: Coiffec, Gaelle; Duhamel, Erwan; Biseau, Alain; Danzart, Marc.
Since 1993 the yearly amounts of sardine landings for the Bay of Biscay fishing ports have experienced a constant increase (10,000 tonnes in 1993); on that account sardine is the first species landed in the fishing ports of the Bay of Biscay (15,000 tonnes in 2003). It is sold 0.54 € / kg (constant price over ten years) which means a 8,100 k€ turnover in 2003 and the 12th rank in value landed in the fishing ports of Bay of Biscay. Though anchovy landings have decreased over the last ten years, especially since 2001, this species occupies the 3rd rank of the highest landings (7,300 tonnes) of the Atlantic shoreline in 2003.The decrease of anchovy landings over the last ten years may account for the high increase of its constant sale price of 1.5 € / kg from...

Analyse des stratégies d'occupation du domaine maritime côtier : le cas des concessions conchylicoles. Rapport final du projet ASTRODOME
Provedor de dados: 5
Autores: Mongruel, Remi; Perez Agundez, José A.; Girard, Sophie; Bailly, Denis; Nassiri, Abdelhamid.
1. The ASTRODOME research project aims to study the economic aspects of the system of allocation and transmission of shellfish concessions, which is considered as an essential element in the understanding of the occupancy strategies of the coastal maritime space. Two series of questions are highlighted. The first series examines the system from a sectorial development point of view: what are the shellfish farmers' needs that the implementation of a quasi concession market satisfied, and to a larger extent, what is the contribution of the evolution of the system of allocation and transmission of concessions to the evolution of the sector's structure? The second series takes a look at the system from a collective interest point of view: to what extent does...

Analysing the Impact of Decoupling at a Regional Level in Ireland: A Farm Level Dynamic Linear Programming Approach
Provedor de dados: 31
Autores: Shrestha,   Shailesh; Hennessy,   Thia C.
This paper describes a methodology to assess the impact of the decoupling of payments on Irish farms at a regional level. The methodology is based on a farm level dynamic linear programming model which optimises regional gross margin under a set of constraints. Regionally representative farms are selected using cluster analysis. The model maximises aggregate gross margins from all the farm types in a region allowing land and milk quota to transfer between farms within the region. The model is estimated for a baseline scenario, assuming no policy change, and under a decoupled scenario where farm payments are fully decoupled from production. An example of an impact study at the Border region in Ireland is presented in this paper to demonstrate the methodology.

Analysing Wine Buying Behaviour in Hungarian Hypermarkets
Provedor de dados: 31
Autores: Szabo,   Zoltan; Szeles,   Zsuzsanna.
In Hungary the amount of money spent on wine marketing is much below the level as it should be and the amounts spent are largely to support direct selling. Choosing the right distribution channel is of key importance. My objective was to identify wine buying behavior of consumers in the hypermarket. I have chosen this type of distribution channel because it is the fastest growing one in Hungary and the largest in wine trade and compared to the international situation it plays a leading role. In the article I show the results of analyzing 578 questionnaires. According to the research fou r wine buyer segments were to identify the 'Drinking with friends', the 'Trendy guests', the 'Cognoscente', and the 'Average friends of wine'. These segments are clearly to...

Analysis and Evaluation of Ecosystem Resilience:  An Economic Perspective
Provedor de dados: 31
Autores: Vergano,   Lucia; Nunes,   Paulo A.L.D.
This paper focuses on the analyses and evaluation of resilience anchored in an economic perspective. Resilience, as well as most of the benefits provided by ecosystems, is not priced on current markets. However, this does not mean that resilience is of no value for humans. On the contrary, the interest of using an economic perspective, and the respective scientific methodology, will be put forward in terms of resilience relevance for ecosystems’ life and functioning, and its impact on human welfare. The economic perspective is anchored in an anthropocentric analysis meaning that resilience is evaluated in terms of provision of natural capital benefits. These, in turn, are interpreted as an insurance against the risk of ecosystem malfunctioning and the...

Autores: D`angelo,José Alejandro.
Spectroscopic information (functional groups and semi-quantitative data) of corystosperm cuticles and compressions from the Triassic of Cacheuta, Mendoza, Argentina, is reported for the first time. Fossil leaves of Johnstonia spp. (Corystospermales, Corystospermaceae) were analyzed by Fourier transform infrared spectroscopy (FT-IR) in an attempt to identify spectroscopic patterns that would characterize these taxa. Infrared spectra obtained from cuticles and compressions of Johnstonia spp. showed a relatively rich aliphatic structure as well as hydroxyl, carbonyl and some other oxygen-containing functional groups. Semi-quantitative data derived from FT-IR spectra were statistically analyzed using one-way analysis of variance test (ANOVA). In the three taxa...

Towards resolving the role of governance in economic development, a model of factualcounterfactual analysis was formulated to determine the relative preference of two different regimes for agriculture in the public expenditure budget of developing countries. The poster is in eight main slides: Introduction (1); Model presentation (2, 3); Application to Nigeria (4,5); Empirical Results (6, 7); Conclusion (8). The results indicate that (a) the military showed greater preference for capital allocations to agriculture in the budget while the civil regime showed greater preference for recurrent allocation, which reflects the presence of strong opposition during the civilian regime that tends to over blow the size of civil service workforce engaged in...

India is the largest producer, consumer, and exporter of spices in the world. The demand scenario for major spices in India has been comprehensively examined in the study. The shift in preferences of domestic consumers for food items, increasing urbanization and rising incomes, altered demographic and social factors and the changes in productivity of spices have brought about changes in the pattern of their consumption and demand. A two-stage budgeting framework, which is a recent development in the theory, of demand with quadratic terms of total expenditure / food expenditure and is an appropriate technique for computing the expenditure elasticities, has been employed to work out the expenditure elasticities for spices in India. The resultant expenditure...

The USDA's Farm Service Agency (FSA) serves as the nation's lender of last resort by providing direct loans to farmers unable to obtain credit at reasonable rates and terms. Annual loan losses have been substantial, averaging $576 million for fiscal 1994-2004. An econometric model using survey data from a sample of FSA loans originated in fiscal 1994-1996 is estimated to identify factors associated with loan losses. The results indicate previous debt settlement experience, loan type, farm type, farm size, and farm financial characteristics are important factors. This information may be used by FSA to adjust its underwriting standards in an effort to reduce loan losses and provide additional loans to farmers given its current funding.

Cladistic analyses were undertaken of Anacardiaceae using non-sequence data (30 genera and 81 characters from morphology, anatomy, palynology and chemotaxonomy), sequence data (26 genera – rbcL) and a combined dataset of 16 genera. All analyses supported a group of genera which can be recognised at the subfamily level: Anacardioideae. Sequence data and combined datasets supported the recognition of a second subfamily: Spondiadioideae Kunth emend. Wannan. Both datasets also suggested that Buchanania lies outside both subfamily groups.

Actinobacillus actinomycetemcomitans (Aa) is considered a major etiologic agent of aggressive periodontitis but this species has also been associated with other forms of periodontal disease. Further, highly leukotoxic strains are related to severity of disease. The purpose of this study was to determine the prevalence of Aa and the occurrence of the leukotoxin gene 530-bp deletion in patients with generalized aggressive periodontitis (GAP) from a Brazilian population. Thirty periodontally healthy and 29 GAP subjects participated in the study. Full-mouth periodontal examination including probing pocket depth (PPD), clinical attachment level (CAL), supragingival biofilm (SB) and bleeding on probing (BOP) was carried out at 6 sites/tooth for all subjects....

Through a survey of scientists from the International Maize and Wheat Improvement Center (CIMMYT) in 2004, this study assessed the extent to which participatory methods had been used by the center, how they were perceived by the scientists, and how participatory research could be applied more effectively by CIMMYT and partners. Results for 19 CIMMYT projects suggest among other things that participatory approaches at the center were largely “functional”—that is, aimed at improving the efficiency and relevance of research—and had in fact added value to the research efforts. The authors suggest that CIMMYT should (1) create a more conducive environment for scientists to share experiences on such approaches and (2) better document their impacts on farmers’...

Analysis of pig meat production with respect to different housing systems of pig
Provedor de dados: 31
Autores: Gajcevic,   Z.; Kralik,   G.; Tolusic,   Zoltan; Margeta,   V.; Kralik,   Igor.
The research focused on two production systems of fattening pigs: conventional system (housing on cross - barred floor) and ecological system (housing on deep litter). Favorable climatic conditions for pig meat production, possibilities to produce cheaper food of better quality and great amounts of litter, are a good basis for making ecological pig production widely accepted by family farms. Ecological aspect of such production of pigs, along with its economic analysis will be key factors, which will influence pig producers in their choice of the most suitable technological solution. In comparison to the conventional way of keeping pigs, main advantages of pig housing on deep litter are cheaper building and equipping of pens, better effect on health...

Analysis of preharvest sprouting in three Brazilian wheat populations
Provedor de dados: 86
Autores: Bassoi,Manoel Carlos; Flintham,John; Riede,Carlos Roberto.
The objective of this work was to evaluate the possibility of obtaining recombinant inbred wheat lines more resistant to preharvest sprouting, independently of colour genes, in three red-grained Brazilian wheat populations. The results showed statistical significance among lines within all populations, which presented a normal distribution and transgressive segregation for preharvest sprouting. The normal distribution of the lines from all red-grained populations suggests that sprouting, excluding the genes expressing seed coat pigmentation, is, probably, controlled by many genes. These findings also indicate that it may be possible to improve resistance to preharvest sprouting, independently of the colour genes.

Analysis of salinity measurements near islands on the French continental shelf of the Bay of Biscay
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie; Kerdreux, Michel.
The Bay of Biscay is characterised by large fresh water inputs from two major rivers, the Loire and the Gironde, with a mean discharge of about 900 m(3)/s. To describe the spatial and temporal variability of the Loire and Gironde plumes, continuous salinity measurements were made at 4 locations on French coastal islands over periods lasting at least two years. These islands are located at a distance from the large local gradients linked to local inputs. Whereas sea surface salinity in the centre of the Bay of Biscay is 35.6, salinities at the coast vary between about 35 in summer to occasionally less than 30 in late winter or in spring. Minimum salinities do not occur at the same time along the coast, indicating a strong spatial gradient. Near the Loire...

It is a fact that conventional agriculture whose distinctive property is the implementation of agricultural chemicals aims to increase economic productivity at the expense of creating serious side effects on health and environment.  Therefore, the spread of this system in time, has led not only to the probing of its sustainability by making the side effects visible, but also to the ascent of organic agriculture which shows a faster worlwide development since the 1990s. The development of organic agriculture in the EU has also been similar.  While the public recognition was realised in the 1990s, the official recognition could not come true before the 2000s.

This study relates the demand for quality foods in Hanoi in terms of its nutritional composition, diversity, price, processing stage, source, and extent eaten outside home with urbanization and enhanced incomes. The vast differences in these foods quality parameters across different socioeconomic groups and regions in and around Hanoi city suggest the changing nature of the food quality with increased income and urbanization. One lesson learned from this analysis is that urbanization and increased income may not necessarily bring all positive changes in food quality. While the diet becomes more balanced in terms of micronutrient, the increased demand for fat-based calories, processed and restaurant foods, and drift away from fresh sources of farm and...

Kidney anion exchanger adaptor protein (Kanadaptin) is a protein which interacts with the cytoplasmic N-terminal domain of kidney anion exchanger 1 (kAE1) and was first detected in mice using the yeast two-hybrid system and was also found to co-localize with kAE1 in rabbit a-intercalated cells. Impaired trafficking of human kAE1 can result in the kidney disease-distal renal tubular acidosis (dRTA), and defective interaction between human kAE1 and kanadaptin may cause this trafficking impairment and be the basis for dRTA pathogenesis. However, it is unknown whether kAE1 can really interact with kanadaptin in humans. We have thus investigated the interaction between human kAE1 and human kanadaptin by using both Gal4 and LexA yeast two-hybrid systems. It was...

Xanthomonas axonopodis pathovar citri (Xac) causes bacterial citrus canker, a serious disease of most citrus species. Xanthomonas campestris pv. campestris (Xcc) is the causal agent of black rot disease in cruciferous plants. In Xcc, cell-cell signaling is mediated by diffusible signal factor (DSF). Synthesis of DSF depends on RpfB and RpfF. DSF perception and signal transduction have been suggested to involve a two-component system comprising RpfC and RpfG. It has been proposed that these proteins participate in a signal transduction system linking changes in the environment to the synthesis of DSF and the expression of virulence genes. Although the cluster of the rpf genes in Xac has synteny with the corresponding cluster in Xcc, two genes (rpfH and...

The quadruple cauliflower mosaic virus (CaMV) 35S enhancer fragment is a strong enhancer, which is most commonly used for this purpose. However, the constitutive nature of this enhancer may generate lethal mutations or aberrations in different plant organs by the same overexpressed gene. A tissue-specific activation tagging approach may overcome these drawbacks and may also lead more efficiently to the desired phenotype. For this reason the SHATTERPROOF2 (SHP2) promoter fragment was analysed for enhancer activity. The SHP2 gene is involved in dehiscence zone development and expressed during silique...

Autores: Odhiambo,   Mark O.; Oluoch-Kosura,   Willis; Kibiego,   Michael B.
Beans are widely grown as a major food crop in Eastern and Southern Africa. It is the most important staple food crop after maize in Kenya (ECABREN, 2000). The beans industry in Kenya is faced with problems of shortages, seasonal supply and price fluctuations and inadequate information on production, marketing and consumption. These problems are more acute in urban areas. This paper analyzes the structure and performance of the beans marketing system in Nairobi metropolitan area, the single most important beans market in Kenya. Data from a sample of 102 traders augmented by secondary data were used to analyze the marketing system by applying descriptive statistics, concentration ratios and co-integration models. The results showed that the beans marketing...

Analysis of the technical efficiency of rice farms in Ijesha Land of Osun State, Nigeria
Provedor de dados: 31
Autores: Tijani,   A.A.
This study estimated technical efficiencies on rice farms in Osun State, Nigeria, and identified some socioeconomic factors, which influence productive efficiency. These technical efficiencies were estimated using the stochastic frontier production function approach applied to primary data. A translog production function was used to represent the production frontier of the rice farms. The study showed that the levels of technical efficiency ranged from 29.4% to 98.2% with a mean of 86.6%, which suggests that average rice output falls 13.4% short of the maximum possible level. Therefore in the short run there is scope to increase technical efficiencies on rice farms in the study area. The study also showed that these efficiencies are positively and...

Analysis of Vocational and Residential Preferences of Rural Population: Application of an Experimental Technique to Rural Slovenia
Provedor de dados: 31
Autores: Zanni,   Alberto M.; Davidova,   Sophia; Bailey,   Alastair.
This study represents the first application of Choice Experiments to the analysis of the monetary and non-pecuniary determinants of vocational choice and spatial labor supply. It identifies the determinants of individual’s choice of jobs and place of residence, and provides a better understanding of the process of rural labor adjustments in a country in transition, Slovenia. The results indicate that the effect of wages, as the main factor influencing employment choice, is counterbalanced by other determinants affecting working conditions and residence. A considerable degree of immobility in terms of migration and commuting has been revealed. As a result, a rapid urbanisation process is unlikely to happen in the near future, according to individuals’...

Wave observations taken during 1986 in Abu-Qir Bay were statistically analyzed to calculate the wave parameters describing the sea state (significant wave height, wave period and predominant direction). On both sides of Rosetta promontory, the transformed wave parameters at break line (breaker height, breaker depth and crest angle) were calculated in terms of the predominant values of the significant wave height, period and direction using ACES software package. Breaker type and closure depth along Rosetta coast were also predicted. Generally, the wave effect in the bay was varying in intensity and direction in accordance with the prevailing wind. The average annual wave height and period are about 0.94 m and 6.5 s, respectively. Throughout the year, the...

Autores: França,Elvis Joacir de; Fernandes,Elisabete A. De Nadai; Bacchi,Márcio Arruda; Saiki,Mitiko.
Instrumental neutron activation analysis (INAA) is a measurement technique of high metrological level for the determination of chemical elements. In the context of BIOTA/FAPESP Program, leaves of trees have been evaluated by INAA for biomonitoring purposes of the Atlantic Forest. To assure the comparability of results in environmental studies, a leaf sample of Marlierea tomentosa (Myrtaceae family) showing the lowest concentrations of chemical elements was selected for the evaluation of analytical quality of the determination under unfavorable conditions. Nevertheless, the homogeneity of chemical concentrations of sample at the 95% of confidence level has been achieved and INAA has presented repeatability of 2% for the determination of Br, Co, Cs, Fe, K,...

Analyzing the Impact of Structural Change in Iranian Agricultural Credit System
Provedor de dados: 31
Autores: Yazdani,   Saeed.
Replacement of the traditional interest based credit system with an Islamic credit system was one of the fundamental changes in Iran since 1979. The Islamic credit system, offers the prospect of risk sharing between the borrower and the lender. Small farmers are likely to be risk averse and they are reluctant to go heavily into debt in order to finance investments in new technology and capital intensive methods of production which they perceive to be risky. Farmer's decision making behaviour with regard to risk under the Islamic and interest based credit systems are explored with the aid of a simple conceptual model. Analysis of attitudinal data suggests that the majority of small farmers prefer credit provided under the Islamic credit system. Farmers'...

Anatomical study on Myoforceps aristatus, an invasive boring bivalve in S.E. Brazilian coast (Mytilidae)
Provedor de dados: 84
Autores: Simone,Luiz Ricardo L.; Gonçalves,Eric Pedro.
The bivalve Myoforceps aristatus (Dillwyn, 1817), also known as Lithophaga aristata, have been recently collected in the coasts of Rio de Janeiro and São Paulo, Brazil; a species that bores shells of other mollusks. This occurrence has been interpreted as an invasion of this species, originally from the Caribbean. The distinguishing character of the species is the posterior extensions of the shell crossing with each other. Because specimens with this character have also been collected in the Pacific Ocean, they all have been considered a single species. However, it is possible that more than one species may be involved in such worldwide distribution. With the objective of providing full information based on Atlantic specimens, a complete anatomical...

For adequate treatment of patients with breast cancer, mastologists should have a complete understanding of the anatomy of the thoracic wall, axilla and breast. However, the classical anatomical descriptions in textbooks make it difficult to gain full mastery of this subject, because the books usually deal with its elements separately. In an endeavor to resolve this difficulty, the present authors have conducted an extensive review, to describe the muscles, blood vessels and nerves of the thoracic wall and in the axilla that are of interest to mastologists. The axilla was described in detail, with emphasis on its limits, walls and contents, and highlighting the lymph nodes in this region. Finally, the anatomy of the breast and its topography, innervation,...

Autores: Böhler, Daniel; Dierauer, Hansueli.
Eiweißerbsen, Ackerbohnen, Sojabohnen und Lupinen werden zurzeit auf Bio-Betrieben nur vereinzelt angebaut. Die Nachfrage nach GVO-freien Futtermitteln wird jedoch immer größer, d.h. dass es in Zukunft immer schwieriger sein wird, genügend Eiweißkomponenten auf dem Markt zu beschaffen, weshalb der Preis eher ansteigen dürfte. Ein weiterer Aspekt ist die Stickstoffeigenversorgung auf dem Biobetrieb, welcher vorwiegend über den Anbau von Leguminosen erfolgt. Betriebe mit Tierhaltung bevorzugen Futterleguminosen, weil diese im Betrieb verwertbar sind, mehr Stickstoff fixieren, das Unkraut besser unterdrücken und mehr zum Aufbau der Bodenfruchtbarkeit beitragen als Körnerleguminosen. Viehlose oder viehschwache Betriebe sind bestrebt den Kunstfutterbau auf ein...

Ancient feeding, ecology and extinction of Pleistocene horses from the Pampean Region, Argentina
Provedor de dados: 41
Autores: Sánchez,Begoña; Prado,José Luis; Alberdi,María Teresa.
To reconstruct the diet and habitat preference of fossil horses, we measured the carbon and oxygen isotope composition of 35 bone and tooth samples of Equus (Amerhippus) neogeus Lund, Hippidion principale (Lund), and Hippidion devillei (Gervais) from 10 different Pleistocene localities in the Pampean region (Argentina). To compare the three species by stratigraphic age, we divided the samples into three groups: lower Pleistocene, middle-late Pleistocene and latest Pleistocene. Samples of Hippidion devillei from the lower Pleistocene were more homogeneous, with &amp;#948;13C values ranging between -11.73 to -9.79&amp;#8240;. These data indicate a diet exclusively dominated by C3 plants. In contrast, Hippidion principale and Equus (Amerhippus) neogeus from...

Andalusian Demand for Non-Market Goods from Mountain Olive Groves
Provedor de dados: 31
Autores: Arriaza Balmón,   Manuel; Gomez-Limon,   Jose Antonio; Kallas,   Zein; Nekhay,   Olexandr.
Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility. The main...

Andreae Vesalii: The Temporomandibular Joint
Provedor de dados: 77
Autores: Vasconcellos,Henrique Ayres de; Barros de Vasconcellos,Pedro Henrique.
The Temporomandibular Joint (TMJ) has been studied for many years since the finding of mummies and fossils. In Egypt of the pharaos, papyrus from the year 3000 B.C. remark the care in which a luxation of the TMJ should be undertaken. In India, at the beggining of the Christian age, in Hipocrates' Greece and in Pergamo of Galenus the TMJ has also been the focus of several studies. But it was Vesalius (Andreae Vesalli), with his particular teaching methodology and publication of his masterpiece De Humani Corporis Fabrica, who showed the way to study Human Anatomy as it is done today. The description of the face bones, of the articular disc and the muscles used for chewing are all a contribution from Vesalius to the anatomic-functional study of TMJ

Angiotensin II type 1 receptor A1166C GENE polymorphism and essential hypertension in San Luis
Provedor de dados: 47
Autores: Lapierre,Alicia Viviana; Arce,María Elena; Lopez,José Raúl; Ciuffo,Gladys María.
Essential hypertension is considered a multifactorial trait resulting from a combination of environmental and genetic factors. The angiotensin II type 1 receptor mediates the vasoconstrictor and growthpromoting effects of Ang II. The A1166C polymorphism of the AT1 receptor gene may be associated with cardiovascular phenotypes, such as high arterial blood pressure, aortic stiffness, and increased cardiovascular risk. We investigated the association between this A1166C polymorphism and hypertension in hypertense and normotense subjects from San Luis (Argentina) by mismatch PCR-RFLP analysis. Hypertense patients exhibited significant increases in lipid related values and body mass index. The frequency of occurrence of the C1166 allele was higher among...

Animal dietary intervention study of effect of organic vs conventional food production methods on health and well – being of rats
Provedor de dados: 21
Autores: Rembiałkowska, prof. Ewa.
According to the research studies conducted during last 20 years the wholesomeness and nutritive value of the organically produced crops is often higher than of conventional plant products. Organic crops contain less harmful substances (e.g. pesticide residues, nitrates) and more desirable compounds (e.g. vitamin C, flavonoids) than conventional ones.      However, the impact of the organic food consumption on animal and human health and well being still remains almost unknown. Small experimental mammals fed organically showed in some experiments better health and fertility parameters, but much more research studies are needed in order to broaden our knowledge.     Therefore a dietary intervention study on rats will be conducted at Warsaw Agricultural...

Animal Disease Pre-Event Preparedness versus Post-Event Response:  When is it Economic to Protect?
Provedor de dados: 31
Autores: Elbakidze,   Levan; McCarl,   Bruce A.
We examine the economic tradeoff between the costs of pre-event preparedness and post-event response to the potential introduction of an infectious animal disease.  In a simplified case study setting, we examine the conditions for optimality of an enhanced pre-event detection system considering various characteristics of a potential infectious cattle disease outbreak, costs of postevent response actions.  We show that the decision to invest in pre-event preparedness activities depends on such factors as probability of disease introduction, disease spread rate, relative costs, ancillary benefits, and effectiveness of mitigation strategies.

We employ a game-theoretic principal agent framework to analyze the individual farmer and governmental behavior pre- and post-animal disease outbreak. We examine the gap between the privately optimal and socially optimal levels of ex ante biosecurity investment and then investigate how a well-designed differentiated compensation scheme can close this gap. Our results also show that the privately optimal investment is generally lower than the first best socially optimal level, and a well-designed differentiated compensation scheme conditional on ex ante biosecurity investment can induce private preventive investment at least greater than the second best socially optimal level when the government face constraints, or even increase approaching the first best...

Animal health and nutrition in organic farming
Provedor de dados: 21
Autores: Vaarst, Mette; Weisbjerg, Martin Riis; Kristensen, Troels; Thamsborg, Stig Milan; White, Andrew; Roderick, Stephen; Lockeretz, Willie.
Animals are important in organic farming systems, both as a part of the concept and in practice, where there is great weight on forming an integrated system with harmony between the land, the animals and the people, involving local recirculation of feed and manure. Good animal health and welfare is an important goal for organic husbandry. In contrast to crops, animals are not just parts of the farming system, they are also sentient creatures and as such they deserve special moral consideration. They are individuals that need to be cared for, they can suffer, and they can interact with each other and with the humans and environment around them. Animal management is, therefore, very different from crop management. Humans have a moral obligation to treat...

Sixty organic pig producers from Denmark, UK, the Netherlands, Germany, and Sweden have completed a questionnaire concerning health and welfare problems in organic sow herds. Half the farmers perceived they had a problem with piglet mortality. The most common cause of death was crushing of piglets by the sow, but also piglets that were weak at birth and shortage of milk in the sow caused problems in many herds. Weaning diarrhoea concerned 25 % of the farmers, mainly in Denmark, Germany and the Netherlands; and respiratory diseases caused prob-lems in 43 % of the farms, especially in the Nether-lands. Diarrhoea was the major cause of death in Danish weaned pigs; in the Netherlands they were more likely to die from respiratory diseases, while insufficient...

Organic livestock production is a means of food production with a large number of rules directed towards a high status of animal welfare, care for the environment, restricted use of medical drugs and the production of a healthy product without residues (pesticides or medical drugs). The intentions of organic livestock production have been formulated by the International Federation of Organic Agriculture Movements (IFOAM) and were further implemented by EU regulation 2092/91 in the year 2000. The consequences of these rules for the health of the animals were not yet fully anticipated at the time these regulations were made and it has become clear that in some cases the rules are not clear enough thereby even hampering the development of the production...

Animal welfare concepts and strategy for poultry production: a review
Provedor de dados: 89
Autores: Moura,DJ; Nääs,IA; Pereira,DF; Silva,RBTR; Camargo,GA.
Well being of animals had been historically a public concern, since the beginning of human kind history. As world's population grows there is a need for food including meat. In the last decades there has been a great improvement in poultry production based on the careful control of several aspects, among which nutrition and management (environment, health and rearing systems). Nowadays, the search for good welfare conditions is a global tendency in animal production; however issues surrounding farm animal welfare or well-being, such as definitions, measurements, interpretation, and perception, continue to be controversial. It is known that the result of a broiler not adequately housed is a direct loss in production which leads towards a thought that...

Animal-based agriculture, phosphorus management and water quality in Brazil: options for the future
Provedor de dados: 63
Autores: Shigaki,Francirose; Sharpley,Andrew; Prochnow,Luís Ignácio.
Eutrophication has become a major threat to water quality in the U.S., Europe, and Australasia. In most cases, freshwater eutrophication is accelerated by increased inputs of phosphorus (P), of which agricultural runoff is now a major contributor, due to intensification of crop and animal production systems since the early 1990s'. Once little information is available on the impacts of Brazilian agriculture in water quality, recent changes in crop and animal production systems in Brazil were evaluated in the context of probable implications of the fate of P in agriculture. Between 1993 and 2003, there was 33% increase in the number of housed animals (i.e., beef, dairy cows, swine, and poultry), most in the South Region (i.e., Paraná, Rio Grande do Sul, and...

Provedor de dados: 102
Autores: Silveira,Silvaldo F.; Harrington,Thomas C.; Mussi-Dias,Vicente; Engelbrecht,Christine J. B.; Alfenas,Acelino C.; Silva,Carolina R.
Mango branch blight disease, caused by Ceratocystis fimbriata, is endemic to the municipality of São Fidelis in northern Rio de Janeiro State. In addition to mango, C. fimbriata was found associated with sugar apple trees (Annona squamosa) showing symptoms of branch blight in São Fidelis. Sugar apple and mango isolates from the same region had the same morphology and showed similar ITS-rDNA sequences. These sequences were also similar to other Brazilian isolates of C. fimbriata sensu stricto. Cross inoculation of such isolates obtained from diseased sugar apple and mango resulted in diseased symptoms on both plant species. This is the first record of A. squamosa as a host for C. fimbriata.

Ecological conditions in breeding and non-breeding areas of migrant birds have been linked to their annual survival and production of young, but the role of stopover sites is under-appreciated. Through banding studies and censuses along the flyway from Tierra del Fuego to the Canadian Arctic, the drastic decline in 2000-2001 of Red Knots (Calidris canutus rufa) population summering in southern South America in the northern winter was shown to be related to the overharvesting of horseshoe crabs (Limulus polyphemus) in Delaware Bay, USA, their last stopover site before reaching their breeding grounds, and to the late arrival of the birds at this site. In San Antonio Oeste, Argentina, where 25-50% of the Tierra del Fuego Red Knots population congregates every...

ANOMALIES IN VOTING: AN EXPERIMENTAL ANALYSIS USING A NEW, DEMAND REVEALING (RANDOM PRICE VOTING) MECHANISM
Provedor de dados: 31
Autores: Messer,   Kent D.; Poe,   Gregory L.; Rondeau,   Daniel; Schulze,   William D.; Vossler,   Christian A.
This study investigates the influence of social preferences on voting decisions using a new Random Price Voting Mechanism (RPVM), which is best thought of as a public goods voting extension of the Becker-DeGroot-Marshack mechanism for private goods. In particular, this mechanism is used to investigate experimentally whether voting decisions are affected by the distribution of net benefits associated with a proposed public program. Recent papers have shown that, in additional to selfishness, factors such as inequality aversion, maximin preferences, and efficiency may influence individual decisions. However, the effect of social preferences on voting, the predominant funding mechanism for public goods by legislatures and public referenda, has not been...

Anomalous Lobar Pattern of Right Lung: A Case Report
Provedor de dados: 77
Autores: Modgil,Vishal; Das,Srijit; Suri,Rajesh.
The right lung classically has two fissures, an oblique and a horizontal, dividing it into three lobes namely the superior, middle and lower. The anomaly of the lobar pattern has been described by many research workers on CT scans, where as, there are fewer studies on gross anatomical specimens. In the present case , which was incidentally detected, we report three fissures dividing the right lung into four lobes. Such abnormal fissures and lobes are clinically important for identifying broncho-pulmonary segments. Anatomical knowledge of anomalies of fissures and lobes of lungs may be important for surgeons performing lobectomies, radiologists interpreting X ray and CT scans and also of academic interest to all medical personnel

This paper provides an overview of what the Millennium Ecosystem Assessment (MA) calls &amp;#8220;indirect and direct drivers&amp;#8221; of change in ecosystem services at a global level. The MA definition of a driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely by altering one or more direct drivers. Global driving forces are categorized as demographic, economic, sociopolitical, cultural and religious, scientific and technological, and physical and biological. Drivers in all categories other than physical and biological are considered indirect. Important direct drivers include changes in climate,...

Autores: Suffredini,Ivana Barbosa; Paciencia,Mateus Luís Barradas; Varella,Antonio Drauzio; Younes,Riad Naim.
Infections caused by multiresistant bacteria are a widespread problem, especially in intensive care units. New antibiotics are necessary, and we need to search for alternatives, including natural products. Brazil is one of the hottest spots in the world in terms of biodiversity, but little is known about the chemical and pharmacological properties of most of the plants found in the Amazon rain forest and the Atlantic Forest. We screened 1,220 organic and aqueous extracts, obtained from Amazon and Atlantic rain forest plants, against Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa and E. coli. Seventeen organic and aqueous extracts obtained from 16 plants showed activity against both Gram-positive bacteria. None of the extracts showed...

We evaluated the antibacterial activities of the crude methanol extract, fractions (I-V) obtained after acid-base extraction and pure compounds from the stem bark of Aspidosperma ramiflorum. The minimum inhibitory concentration (MIC) was determined by the microdilution technique in Mueller-Hinton broth. Inoculates were prepared in this medium from 24-h broth cultures of bacteria (10(7) CFU/mL). Microtiter plates were incubated at 37ºC and the MICs were recorded after 24 h of incubation. Two susceptibility endpoints were recorded for each isolate. The crude methanol extract presented moderate activity against the Gram-positive bacteria B. subtilis (MIC = 250 µg/mL) and S. aureus (MIC = 500 µg/mL), and was inactive against the Gram-negative bacteria E. coli...

The aim of this study was to investigate the antibacterial activity of propolis samples from Goiás, Paraná and São Paulo States, Brazil, and their flavonoids content. Ethanolic extracts of propolis (EEP) were prepared (30g of propolis in 70% ethanol), and the microorganisms Staphylococcus aureus and Escherichia coli were tested. The methodology employed was agar diffusion using filter paper discs. Ampicillin and tetracycline were used as controls. Antibacterial activity was determined by the reading of inhibition zone diameters (mm) after 24 hours incubation at 37°C. Results demonstrated that EEP inhibited the growth of Staphylococcus aureus but not that of Escherichia coli. Tetracycline and ampicillin showed an efficient action against both bacteria....

One of the most important problems involving treatments with antibiotics against Aeromonas hydrophila isolated from fishes is that antibiotic resistance develops readily. The antimicrobial activity of chemotherapeutants in isolates from pacu Piaractus mesopotamicus (Holmberg, 1887) and tilapia Oreochromis niloticus (Linnaeus, 1758) was tested by the Kirby-Bauer disk method, over Mueller-Hinton surface agar previously inoculated with 100 µL of bacterial suspensions. After regular incubation, isolates from tilapia and pacu were uniformly resistant to amoxicillin, ampicillin, lincomycin, novobiocin, oxacillin, penicillin, and trimetoprim+sulfametoxazole. The A. hydrophila type strain presented resistance to the same antimicrobial substances and also against...

Antibiotics for the empirical treatment of acute infectious diarrhea in children
Provedor de dados: 55
Autores: Diniz-Santos,Daniel R.; Silva,Luciana R.; Silva,Nanci.
While the routine use of antibiotics for infectious diarrhea in children must be avoided, because it brings little benefit in most cases and is associated with the risk of increasing antimicrobial resistance, selected cases may require antimicrobial therapy, and the choice of the antimicrobial agent often has to be made empirically. Physicians prescribing antimicrobials in such a setting have not only to be aware of the most likely pathogens, but also of their characteristic antimicrobial susceptibility pattern and the safety profile of the various drugs. We reviewed the literature on the use of ampicillin, beta-lactamase inhibitors, trimethoprim-sulfamethoxazole, chloramphenicol, tetracyclines, nalidixic acid, fluoroquinolones, third-generation...

A lagarta da soja, Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae) é a principal desfolhadora da soja no Brasil, sendo encontrada em todos os locais de produção, representando um risco à produção e à qualidade dos cultivos brasileiros (GAZZONI e YORINIORI, 1995; MOSCARDI e SOUZA, 2002). Este inseto causa grandes danos à lavoura de soja, que vão desde o desfolhamento até a destruição completa da planta. A lagarta da soja é um inseto mastigador e se alimenta de folhas jovens. Quando a folhagem é removida, ataca outras partes da planta, como pecíolos e a haste. O desfolhamento compromete o enchimento das vagens, devido à diminuição da área foliar responsável pela fotossíntese, com conseqüente redução da produção de grãos. Quando se alimentam, além...

The prevalence of small ruminant lentivirus (SRL) infection was evaluated in goats and sheep in two counties of Pernambuco State, Brasil. Seriological examinations were performed from a total of 672 goats and 325 sheep, one year of age and older, at two abattoirs. Sera were analyzed by agar gel immunodiffusion using Maedi-Visna K-1514 antigens. There were 42 reactive samples (95% confidence interval 3.6% to 4.9%) in both slaughter houses. In São Lourenço da Mata county, 3.2% and 4.0% of goat and sheep sera were responsive, whereas in Paulista county, 5.1% of goat samples and 8.2% of sheep were reactive.

Provedor de dados: 45
Autores: Corradi,D.A.; Carvalho,V.M.; Coutinho,S.D.
The occurrence of serum antibodies to Borrelia burgdorferi in professionals in close contact with wild animals was determined. Seventy eight technicians workers coming from two São Paulo public institutions housing wild animals had their blood collected (serum samples). All samples were submitted to ELISA for IgM and IgG antibodies against Borrelia burgdorferi. The results showed five positive (6.4%), two suspect (2.6%) and 71 negatives (91%) samples. Based on positive results it is concluded that the infection level is higher to that detected in the general population and similar to values of endemic areas, concluding that this assessed population could be considered at risk for Lyme disease.

Antidumping Duties in the Agriculture Sector: Trade Restricting or Trade Deflecting
Provedor de dados: 31
Autores: Kassam,   Shinan; Malhotra,   Nisha.
The key issues on the negotiation table in the agriculture sector are the elimination of export subsidies, a progressive reduction of tariffs and reduction in domestic support. However, it is observed that trade liberalization often involves moving from one set of distortions to another rather than a movement to free trade.   More specifically, in the case of trade liberalization in manufacturing, countries have replaced lower tariffs with antidumping duties (ADD).  Feinberg and Olson (2005) empirically show that countries that agreed to larger tariff reductions under the Uruguay Round are more likely to use AD statutes to protect their domestic industries.  Thus if the use of ADD in agriculture are effective as a trade barrier (that is there is little...

Autores: Faria,Terezinha de Jesus; Ferreira,Rafael Sottero; Yassumoto,Lidiane; Souza,José Roberto Pinto de; Ishikawa,Noemia Kazue; Barbosa,Aneli de Melo.
An investigation of antifungal activity of the essential oil obtained by steam-distillation (1.1% w/w) of the aerial parts of Ocimum gratissimum and of an ethanolic extract from the steam-distillation residue was carried out using the agar diffusion method. The results revealed that the essential oil inhibited the growth of all fungi tested, including the phytopathogens, Botryosphaeria rhodina, Rhizoctonia sp. and two strains of Alternaria sp., while the extract from the residue was inactive. The essential oil was subjected to TLC bioautography used to detect fungitoxic constituents. The compound that showed antifungal activity was isolated and identified as eugenol. GC/MS analysis showed that eugenol was the main constituent of the essential oil studied....

Autores: Monteiro,Eduardo José Bellotto; Caron,Daiane; Balda,Carlos Alberto; Franco,Marcello; Pereira,Aparecido Bernardo; Kirsztajn,Gianna Mastroianni.
We report on a case of a patient with HIV infection, diagnosed 18 months prior to the development of an anti-glomerular basement membrane (anti-GBM) rapidly progressive glomerulonephritis; this is probably the first report of such an association. A 30-year-old white man presented with elevation of serum creatinine (1.3 - 13.5 mg/dL within one month). At admission, the urinalysis showed proteinuria of 7.2 g/L and 8,000,000 erythrocytes/mL. Renal biopsy corresponded to a crescentic diffuse proliferative glomerulonephritis mediated by anti-GBM, and serum testing for anti-GBM antibodies was positive; antinuclear antibodies (ANA) and anti-neutrophilic cytoplasmic antibodies (ANCA) were also positive. The patient underwent hemodyalisis and was treated with...

Autores: AGUIRRE,PABLA; MENA,NATALIA; TAPIA,VICTORIA; ROJAS,ALEJANDRO; ARREDONDO,MIGUEL; NÚÑEZ,MARCO TULIO.
Brain cells have a highly active oxidative metabolism, yet they contain only low to moderate superoxide dismutase and catalase activities. Thus, their antioxidant defenses rely mainly on cellular reduced glutathione levels. In this work, in cortical neurons we characterized viability and changes in reduced and oxidized glutathione levels in response to a protocol of iron accumulation. We found that massive death occurred after 2 days in culture with 10 mM Fe. Surviving cells developed an adaptative response that included increased synthesis of GSH and the maintenance of a glutathione-based reduction potential. These results highlight the fundamental role of glutathione homeostasis in the antioxidant response and provide novel insights into the adaptative...

Autores: Cotterill,   Ronald W.
This paper reviews the basic components of antitrust analysis for the supermarket industry, including definition of product and geographic markets and the measurement of market power. The analysis of prices and profits in a market structure context remains important, especially in countries such as Australia with very high supermarket concentration. Firm and brand level New Empirical Industrial Organisation models of demand and oligopoly pricing also provide insights for evaluating antitrust claims. Recent research on vertical pricing games and price transmission expand the analysis to market channel pricing issues, including coalescing power by supermarkets and food manufacturers. The issues and approaches explained in this paper are relevant for...

Apical Maxi-chloride channel from human placenta: 12 years after the first electrophysiological recordings
Provedor de dados: 48
Autores: RIQUELME,GLORIA.
The Maxi-chloride channel was the first ion channel described by electrophysiological methods in placenta. Because it is difficult to access a complex epithelium such as the placenta for electrophysiological procedures, the studies of ion channels from placental membranes have been performed only very recently. It was only in 1993 that a direct demonstration of a high-conductance chloride channel in apical membranes of intact trophoblastic epithelium was mentioned, and two years later, the description of this channel was reported from purified placental apical membranes reconstituted into artificial lipid membranes suitable for patch-clamp recordings. This brief review comments on the work done with regard to the electrophysiological characterization and...

Provedor de dados: 53
Autores: Crusciol,Carlos Alexandre Costa; Soratto,Rogério Peres; Silva,Laerte Marques da; Lemos,Leandro Borges.
Em lavouras de feijão, principalmente em cultivos com alta tecnologia, não tem sido dada a devida atenção ao fornecimento adequado de enxofre (S), utilizando doses subestimadas ou não aplicando o elemento via adubação, o que pode estar sendo um fator limitante ao incremento de produtividade. O objetivo deste trabalho foi avaliar a influência da aplicação de S em cobertura na nutrição, nos componentes da produção e na produtividade de grãos do feijoeiro, em sistema de plantio direto (SPD). O delineamento experimental utilizado foi o de blocos ao acaso, com cinco repetições. Os tratamentos foram constituídos por cinco doses de S (0, 20, 40, 60 e 80 kg ha-1) aplicados em cobertura no estádio V4, tendo como fonte o sulfato de amônio. Aplicação de S em...

Aplicação de hipoclorito de sódio para recuperação de gotejadores entupidos em irrigação com água ferruginosa
Provedor de dados: 91
Autores: Souza,José A. A. de; Cordeiro,Élio de A.; Costa,Édio L. da.
O entupimento dos emissores é o maior problema do sistema de irrigação localizada. Geralmente, esta obstrução causa tanto redução quanto aumento da sua vazão, porém sempre se dá diminuição da uniformidade de distribuição de água do sistema, fato que pode ser minimizado pela aplicação de produtos químicos. O objetivo com este trabalho foi avaliar a aplicação de doses de cloro (50, 100 e 150 mg de cloro livre L-1 de água, T1, T2 e T3, respectivamente) na recuperação da vazão nominal (QN) de gotejadores Netafin-Ram 17, que apresentavam vazão média (QM) superior à QN, em razão de entupimentos ocorridos em dois anos de irrigação com água contendo 1,7 mg L-1 de ferro total. Avaliou-se a recuperação da QN e a uniformidade de distribuição de água dos gotejadores....

O ar atmosférico é formado por uma composição de ar seco e vapor d'água, cujos valores da quantidade de vapor, em termos quantitativos, são variáveis em função dos elementos climáticos, tais como: temperatura e pressão. Portanto, para estimar os valores de umidade relativa do ar, são necessárias informações completas de séries de dados de temperatura do ar (Tar), pressão atual de vapor (e a) e temperatura de bulbo úmido (Tu). O trabalho apresenta como objetivo a elaboração de rotina computacional para encontrar valores da temperatura do termômetro de bulbo úmido (Tu) em função de outras variáveis, para uma série de dados obtidos, mediante a aplicação de métodos numéricos (Método de Newton-Raphson e Método da Secante), para fins de complementação de uma...

A avaliação de terras é o processo que permite estimar o uso potencial da terra com base em seus atributos. Grande variedade de modelos analíticos pode ser usada neste processo. No Brasil, os dois sistemas de avaliação das terras mais utilizados são o Sistema de Classificação da Capacidade de Uso da Terra e o Sistema FAO/Brasileiro de Aptidão Agrícola das Terras. Embora difiram em vários aspectos, ambos exigem o cruzamento de inúmeras variáveis ambientais. O ALES (Automated Land Evaluation System) é um programa de computador que permite construir sistemas especialistas para avaliação de terras. As entidades avaliadas pelo ALES são as unidades de mapeamento, as quais podem ser de caráter generalizado ou detalhado. A área objeto desta avaliação é composta...

Apoptosis and progression of hepatic fibrosis in hepatitis C patients
Provedor de dados: 55
Autores: Schinoni,Maria Isabel; Paraná,Raymundo; Cavalcante,Daniel.
Hepatitis C is a worldwide endemic disease, affecting roughly 200 million people. It has a variable prognosis, depending on the progression to fibrosis. During the last five years, the importance of apoptosis for the pathogenesis of various diseases, including hepatitis, has been recognized. It has been suggested that an increase in T cell-apoptosis during a hepatitis C virus infection is the cause of impaired regulation of the immune cellular response, helping to maintain infection. Thus, the interest in discovering the probable mechanisms by which the hepatitis C virus perpetuates in the liver, and to determine the conditions that predispose for progression of this disease, makes investigation of apoptosis in hepatic injury of great interest. We have...

Application of a Spatial Water Model in a Chinese Watershed
Provedor de dados: 31
Autores: Fang,   Lan; Nuppenau,   Ernst-August.
China’'s fast growing economy has brought some environmental problems, especially in water administration. Inefficiencies in irrigation activities have created severe negative effects to the environment of rural communities, and the more serious water shortages hamper food production, too. Major questions at hand are, how to improve water use efficiency, to reduce negative external effects, to optimize water allocation in agriculture, to invest in water saving technologies, and to assure more water for high value added agriculture. This paper investigates the impacts of irrigation technologies and investments in water saving on the rural economy and the environment. By taking into account individual farmers' inclination to adopt modern water-saving...

Application of Morphological Indices in the Assessment of Type and Function in Sheep
Provedor de dados: 77
Autores: Salako,A. E.
Live weight and eight body measurements records taken on 284 sheep comprising 226 West African Dwarf and 58 Yankasa sheep were analysed. The sheep were extensively managed within the south west Nigeria. The aim was to achieve a preliminary assessment of type and function from zoometrical indices produced from combinations of different morphometric scores. The indices used were weight, height slope, length index, width slope, depth index, foreleg length balance and cumulative index. The body measurements used were wither height, body length, hip length, hip width, rump height, foreleg length, chest width and heart girth. The body measurements showed that the Yankasa is bigger than the WAD sheep. The measured parts are highly correlated. Tested indices...

Autores: Chulaluck Charunuch; Plerncha Tangkanakul; Saovaluk Runggaeng.
Owing to creation of Thai rice snack with health benefits for higher potential in commercial scale, mulberry leaf was applied in the production of extruded snack product. Mulberry leaf in dried powder was mixed with rice, corn, soy, sugar, oil, vitamins and minerals to investigate the operating conditions with twin-screw extruder at varying mulberry content (5, 7.5 and 10%), screw speed (300 and 350 rpm) and feed moisture (13, 15 and 17%) in the 3 × 2 × 3 factorial experiment. The extrudates were examined of functional properties (antioxidant activity and phenolic compounds) and some physical characteristics (expansion ratio, bulk density, texture measurement and organoleptic test). The results had shown that at higher mulberry content (10%), the product...

Application of processed organic municipal solid waste on agricultural land - a scenario analysis
Provedor de dados: 21
Autores: Bruun, Sander; Hansen, Trine L.; Christensen, Thomas H.; Magid, Jakob; Jensen, Lars S.
Source separation, composting and anaerobic digestion, with associated land application, are increasingly being considered as alternative waste management strategies to landfilling and incineration of municipal solid waste (MSW). Environmental life cycle  assessments are a useful tool in political decision-making about waste management strategies. However, due to the diversity of processed organic MSW and the situations in which it can be applied, the environmental impacts of land application are very hard to determine by experimental means. In the current study, we used the agroecosystem model Daisy to simulate a range of different scenarios representing different geographical areas, farm and soil types under Danish conditions and legislation. Generally,...

Application of response surface methodology for glucosyltransferase production and conversion of sucrose into isomaltulose using free Erwinia sp. cells
Provedor de dados: 69
Autores: Yukio Kawaguti,Haroldo; Manrich,Eiric; Harumi Sato,Hélia.
Isomaltulose is a structural isomer of sucrose commercially used in food industries. Glucosyltransferase produced by Erwinia sp. D12 catalyses an intramolecular transglucosylation of sucrose giving isomaltulose. The Experimental design and response surface methodology were applied for the optimization of the nutrient concentration in the culture medium for the enzyme production in shaken flasks at 200 rpm and 30ºC. The three variables involved in this study were sugar cane molasses, bacteriological peptone and yeast extract Prodex Lac SD®. The statistical analysis of the results showed that, in the range studied, all the factors had a significant effect (p &lt; 0.05) on glucosyltransferase production and the highest enzyme activity was observed in culture...

Applications of Relations and Graphs to Coalition Formation

Autores: Berghammer,   Rudolf; Rusinowska,   Agnieszka; de Swart,   Harrie.
A stable government is by definition not dominated by any other government. However, it may happen that all governments are dominated. In graph-theoretic terms this means that the dominance graph does not possess a source. In this paper we are able to deal with this case by a clever combination of notions from different fields, such as relational algebra, graph theory, social choice and bargaining theory, and by using the computer support system RelView for computing solutions and visualizing the results. Using relational algorithms, in such a case we break all cycles in each initial strongly connected component by removing the vertices in an appropriate minimum feedback vertex set. So, we can choose an un-dominated government. To achieve unique solutions,...

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 can be imple-mented immediately. As the experiments are often performed on single farms the results are difficult to transfer to other locations. Controlled experiments with animals on group level with representative sam-ples investigate single factors and lead to reliable and well-founded results. However, they are often far away from implementation into agricultural practise. Applied research requires an interplay of on farm research and controlled experiments. A series of ethological research work at research institute of organic agriculture in Switzerland should show how this interplay may take place.

Approaches for field assessment of resistance to leaf pathogens in spring barley  varieties
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Hovmøller, M.S.; Østergård, H.
The resistance of spring barley varieties to powdery mildew, leaf rust, leaf scald and net blotch was characterized by using results from inoculated small-plot nurseries and larger survey plots subject to natural infection. The experiments were conducted in different environments. Both trial types often yielded complementary results with respect to the ranking of varieties suggesting that a recommended variety characterization should include both naturally infected survey-type trials and nursery trials in which the most relevant pathogen isolates and/or isolate mixtures or populations are used for inoculation. Average and median values of the diseased leaf area of a variety were highly correlated with each other and with the genotype main effect determined...

Coastal fish populations settle more or less frequently, at various stages, estuarine systems. Tidal marshes are one of the components of these mosaics of habitats. The first part of this work describes fish assemblages through the utilisation of these systems by fishes analysed in order to propose a revised functional classification of ecological guilds. T h i s new classification is used to compare fish communities of four estuarine systems in the western coast of France: the Mont Saint- Michel Bay, the Saint-Brieuc Bay, the Loire estuary and the Aiguillon Bay. The second part aims at characterizing the nursery function as defined by Beck et al. (2001). Acombinative approach based on gut content analysis, and stable isotope analysis shows that Yo Y s e a...

Aquaculture Productivity Convergence in India: A Spatial Econometric Perspective
Provedor de dados: 31
Autores: Paraguas,   Ferdinand J.; Dey,   Madan Mohan.
This paper provides an illustration of evaluating productivity convergence using spatial econometric modelling framework for the aquaculture sector in India. Productivity has been measured using Total Factor Productivity (TFP). The b- and s-convergence concepts that are used to test the convergence hypothesis have been extended to examine the possible presence of spatial autocorrelation and spatial heterogeneity. The results have confirmed the productivity convergence hypothesis, the presence of spillover effects on TFP growth and the presence of spatial regimes in the TFP convergence process which have policy implications. The paper concludes by providing recommendations for further research.

Autores: Wheeler,   Erin A.; Segarra,   Eduardo; Johnson,   Phillip N.; Willis,   David B.; Johnson,   Jeffrey W.
Irrigated agriculture has played a vital role in the development and growth of the Great Plains Region of the United States. The primary source of water for irrigation in this region is the Ogallala Aquifer. The Southern portion of the Ogallala Aquifer is considered exhaustible due to the low level of recharge relative to the quantities of water pumped. Analysis and evaluation of water conservation policies which could extend the economic life of the Ogallala Aquifer in the Southern High Plains of Texas and Eastern New Mexico, and which could contribute to maintaining the viability of the regional economy is important. This study evaluates the impacts of water conservation policies which limit drawdown of the Ogallala Aquifer. County level dynamic...

One of the fungal pathogens that causes more agriculture damage is Botrytis cinerea. Botrytis is a constant threat to crops because the fungus infects a wide range of host species, both native and cultivated. Furthermore, Botrytis persists on plant debris in and on the soil. Some of the most serious diseases caused by Botrytis include gray mold on vegetables and fruits, such as grapes and strawberries. Botrytis also causes secondary soft rot of fruits and vegetables during storage, transit and at the market. In many plant-pathogen interactions, resistance often is associated with the deposition of callose, accumulation of autofluorescent compounds, the synthesis and accumulation of salicylic acid as well as pathogenesis-related proteins.

Provedor de dados: 58
Autores: Trindade,Aldo Vilar; Siqueira,José Oswaldo; Stürmer,Sidney Luiz.
The aim of this study was to obtain knowledge on arbuscular mycorrhizal (AM) associations in papaya (Caricapapaya, L.) in field soils and nursery conditions. Sixty seven soil and root samples were taken in February and May of 1996, from 47 commercial plantations in the North of Espirito Santo State and the West and South of Bahia State, in Brazil. Samples were used for direct spore counts, root colonization assessment and for trap culture with Sorghumbicolor (L.) Moench and Crotalariajuncea L. Additional sampling was done in commercial nurseries to evaluate mycorrhizal colonization. Although papaya cropping systems are usually under high input of fertilizers and pesticides, papaya roots showed considerable arbuscular mycorrhizal (AM) colonization, ranging...

Are Agricultural Policies Making Us Fat? Likely Links Between Agricultural Policies and Human Nutrition and Obesity, and their Policy Implications
Provedor de dados: 31
Autores: Alston,   Julian M.; Sumner,   Daniel A.; Vosti,   Stephen A.
Rates of obesity among adults and children in the U.S. are soaring, with potentially huge private and social costs. Increasing attention is being paid to agricultural policies as both the culprits through their perceived roles in reducing the relative prices of energy-dense foods, and as the potential saviors through their perceived ability to do the opposite. However, the effects of agricultural policies on human nutrition and obesity are not well understood. This paper considers (1) trends in agricultural commodity prices, and the contributions of commodity policies and agricultural R&amp;D policies to those trends, (2) the links between changes in commodity prices and changes in food prices; and (3) the implications of price-induced changes in food...

Are Citizens Willing to Pay for Agricultural Multifunctionality?
Provedor de dados: 31
Autores: Kallas,   Zein; Gomez-Limon,   Jose Antonio; Arriaza Balmón,   Manuel.
Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of cereal steppes in Tierra de Campos (Spain) as a case study. The economic valuation technique used is the Choice Experiment. The results suggest the existence of a significant demand for the different functions, although this demand is heterogeneous, depending on the socio-economic characteristics of the individuals.

Are Cooperatives Efficient When Membership is Voluntary?
Provedor de dados: 31
Autores: Leathers,   Howard D.
If profit-maximizing farmers are free to join or not to join a cooperative, it may appear reasonable to assume that a cooperative will exist only when it has cost advantaged over non-cooperative marketing. This paper presents a model in which that result fails. Every individual farmer chooses either to join or not join a cooperative depending on whether transactions costs are lower from cooperative membership or nonmembership. As cooperative membership increases, transactions costs for members decline, but for nonmembers these costs increase. Results of this analysis reveal that an equilibrium exists in which all farmers voluntarily choose to join the cooperative, but more than half of the members wish the cooperative had not been formed, and transactions...

Are Corn and Soybean Options Too Expensive?
Provedor de dados: 31
Autores: Urcola,   Hernan A.; Irwin,   Scott H.
A growing body of recent evidence suggests that premiums for financial options might be too high. For agricultural options, market participants often make similar claims, however there is very limited scientific literature to prove or disprove such claims. This research investigates the efficiency of corn and soybean options markets by directly computing trading returns. Time effects on market efficiency are also investigated. When the sample period is considered as a whole, risk adjusted returns indicate that no profits can be made by taking either side of the corn or soybean options markets. However, when time effects are analyzed, corn calls appear to have provided excess returns during the 1998--2005 period. This result do not appear to be driven by...

Are Countries of Association of South East Asia Nations (ASEAN) Candidates of Optimum Currency Area for Monetary Union? A Structural VAR Approach
Provedor de dados: 31
Autores: Sin,   Lew Yuen; Asam Tuan Lorik,   Ku.
Intra-trade among ASEAN countries have remained around 20% over the period 1993 until 2001 (ASEAN Secretariat). With this significant amount of trade being conducted between members of ASEAN countries, businesses were faced with exchange rate exposure due to the volatility of the exchange rate within the regions as was experienced during the Asian Financial Crisis of 1997-98. Members of the European Union overcome this exchange rate exposure by agreeing to form a monetary union and adopting Euro as their common currency in 1999. This paper examines the feasibility of a Optimum Currency Area (OCA) for ASEAN 9 to adopt a common currency, especially after the 1997-98 Asian Financial Crisis. Using macro-economic data for 9 ASEAN countries over the 15 years...

Are Diets Converging Globally? A Comparison of Trends Across Selected Countries
Provedor de dados: 31
Autores: Regmi,   Anita; Unnevehr,   Laurian J.
Converging food demand is tested in two ways. First, the convergence of food expenditures among 18 high-income countries is examined from 1990 to 2004. Convergence is apparent in total expenditures, cereals, and meats, but not in other categories. Second, specific food-retailing and product-introduction patterns are examined for selected countries. These indicate increasing shares for retail outlets selling standardized products and increased preference for convenience, upscale, and natural product attributes across all the countries examined.

Are Direct Payments for Environmental Services Spelling Doom for Sustainable Forest Management in the Tropics?
Provedor de dados: 7
Autores: Wunder, Sven; Center for International Forestry Research; s.wunder@cgiar.org.
Over the past several decades, significant donor funding has been directed to sustainable forest management in the tropics, in the hope of combining forest conservation with economic gains through sustainable use. To date, this approach has produced only modest results in terms of changed silvicultural and land-use practices in this area. Direct payments for environmental services (PES) have been suggested as a promising alternative but still remain widely untested in the tropics. This paper first provides a conceptual assessment of PES, comparing the main features of this practice with those of other conservation instruments. Second, the paper discusses a series of critical questions that have been raised about both the environmental and livelihood...

Are growth and density quantitative indicators of essential fish habitat quality? An application to the common sole Solea solea nursery grounds
Provedor de dados: 5
Autores: Gilliers, Camille; Le Pape, Olivier; Desaunay, Yves; Morin, Jocelyne; Guerault, Daniel; Amara, Rachid.
Bio-indicators were measured on juvenile fish to assess the quality of eight coastal and estuarine nursery grounds in the Eastern English Channel and in the Bay of Biscay during 3 years. Growth (size and otolith daily increment width), body condition (morphometric index) and abundance of juvenile common soles were analysed together with xenobiotic concentrations (heavy metals and organic contaminants).   Condition indices displayed important variations and did not allow relevant estimation of environmental quality. On the contrary, growth and density indicators showed good steadiness above years but varied among sites. In spite of difficulties of interpreting these indicators on such a meso-scale approach, analyses highlighted the estuaries of Seine and...

Are Hospitals Seasonally Inefficient? Evidence from Washington State Hospitals
Provedor de dados: 31
Autores: Friesner,   Daniel L.; McPherson,   Matthew Q.; Rosenman,   Robert.
Efficiency measurement has been one of the most extensively explored areas of health services research over the past two decades. Despite this attention, few studies have examined whether a provider’s efficiency varies on a monthly, quarterly or other, sub-annual basis. This paper presents an empirical study that looks for evidence of seasonal inefficiency. Using a quarterly panel of general, acute-care hospitals from Washington State, we find that hospital efficiency does vary over time; however, the nature of this dynamic inefficiency depends on the type of efficiency being measured. Our results suggest that technical and cost efficiency vary by quarter. Allocative and scale efficiency also vary on a quarterly basis, but only if the data are jointly...

Are the Mediterranean countries competitive in fresh fruit and vegetable exports?
Provedor de dados: 31
Autores: Nilsson,   Fredrik O.L.; Lindberg,   Emma; Surry,   Yves R.
The Barcelona Agreement was signed in 1995, setting forth a structure with bilateral agreements between the EU and twelve Mediterranean countries. The agreement also foresaw the creation of a free trade area in the Euro-Mediterranean region by 2010. For many of the countries surrounding the Mediterranean sea, fruit and vegetables are very important products. In light of the increasing trade liberalization and thus increasing competition between countries, this paper aims to investigate further the competitiveness of Mediterranean countries with respect to fresh fruit and vegetables. The results generally show that the competitiveness of the investigated countries has deteriorated over the period. In only two cases, there is an increase in competitiveness.

Are the motives of recent adopters in line with the conventionalisation hypothesis?
Provedor de dados: 21
Autores: Best, Henning.
To contribute to the discussion on the con-ventionalisation hypothesis, empirical data on mo-tives for the conversion to organic farming by recent adopters is analysed. The results indicate that the preferences and attitudes of the new organic farmers contradict the conventionalisation scenario: (1) Com-pared to conventional farmers, the new adopters have lower preferences for high yields, market prices and easy control of weed and pests, but higher prefer-ences for receiving subsidies and not using chemicals. (2) Environmental concern has an effect on the odds of an adoption of organic farming. Thus, new organic farmers significantly differ in their preferences and attitudes from conventional farmers – they hold a less productivist, relatively alternative...

Based on a large-scale survey conducted in 11 large and small eastern cities in 2002, this study employs ordered probit models to estimate the effects of demographic and socio-economic variables on the likelihood of biotech food acceptance in China. This study also employs a dichotomous choice model to estimate consumers' mean willingness to pay (WTP) for biotech foods, including soybean oil and insect-resistant biotech rice. This survey reaffirms that Chinese urban consumers had a low awareness of biotechnology. Despite the low level of awareness, a great majority of respondents had favorable or neutral attitudes toward biotech foods. Only 5-15 percent was strongly or relatively opposed to biotech foods. Results from the models suggest that mid- and...

To improve the quality of the resource assessment it is necessary to estimate discards and quantify them applying an adequate methodology. The purpose of this work is to detect areas where the activity of the commercial fleet coincides with zones of high concentration of juveniles because they are potential discard areas. To establish possible seasonal and/or interannual variations, length distribution data derived from hake research surveys carried out on board of INIDEP vessels during the 1986-1993 period were analyzed. Samples were grouped per statistical rectangle on the basis of catch weighted average and mean, variance, skewness and kurtosis were calculated. The resulting parameters were subjected to a cluster analysis using the Euclidean distance...

Argentinean cultivars of Vitis vinifera grow better than European ones when cultured in vitro under salinity
Provedor de dados: 47
Autores: Cavagnaro,Juan B.; Ponce,María T.; Guzmán,Javier; Cirrincione,Miguel A.
Argentinean Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making. In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabernet Sauvignon and Chardonnay and four Argentinean cultivars, Cereza, Criolla Chica, Pedro Gimenez and Torrontes Riojano were tested by in vitro culture. Treatments included: 1) Control, 2) 60 mEq/L of a mixture of three parts of NaCl and one part of CaCl2 and 3) 90 mEq/L of the salt mixture. Results from two experiments (I and II) are reported. No differences were...

Provedor de dados: 95
Autores: Alvarez-Pardo,Veronica; Ferreira,Alfredo Gui.
Sementes de dezesseis espécies de orquídeas foram armazenadas a 5ºC por até 42 meses, sendo verificada a viabilidade pelo teste de tetrazólio e de germinação. Houve perda da viabilidade conforme incremento no período de armazenamento. Por doze meses, a maioria das espécies estocadas a 5ºC, em dessecador com umidade relativa de ± 6% de conteúdo de água, conservou a viabilidade próxima aos 100%, com exceção da Cattleya labiata que apresentou queda de cerca de 50% da viabilidade inicial. Cattleya intermedia, Encyclia pygmaea, E. odorantissima, Grobya sp., Oncidium flexuosum, Oncidium pumilum e um híbrido natural, Laeliocattleya conservaram, em geladeira, a viabilidade das sementes acima de 90%, por até 24 meses.

Arm's-Length Transactions as a Source of Incomplete Cross-Border Transmission: the Case of Autos
Provedor de dados: 31
Autores: Hellerstein,   Rebecca; Villas-Boas,   Sofia Berto.
A growing share of international trade occurs through intra-firm transactions, transactions between domestic and foreign subsidiaries of a multinational firm. The difficulties associated with writing and enforcing a vertical contract compound when a product must cross a national border, and may explain the high rate of multinational trade across such borders. We show that this common crossborder organization of the firm may have implications for the well-documented incomplete transmission of shocks across such borders. We present new evidence of a positive relationship between an industry's share of multinational trade and its rate of exchange-rate pass-through to prices. We then develop a structural econometric model with both manufacturers and retailers...

Aromas: parte essencial da qualidade dos vinhos.
Provedor de dados: 14
Autores: GUERRA, C. C.
Várias centenas de compostos aromáticos foram já identificados no vinho. As substâncias aromáticas da uva constituem o chamado aroma varietal, formado por substâncias não aromáticas, que podem tornar-se aromáticas (são os precursores de aromas) e por moléculas aromáticas, chamadas de aromas livres no jargão químico. Ao iniciar o processamento da uva, intervém os fenômenos ligados à tecnologia de vinificação (extração, maceração, hidrólise, oxidação, etc.). Nessa fase formam-se os chamados aromas pré-fermentativos. O conjunto de aromas varietais e pré- fermentativos constitui o chamado aroma primário do vinho. Na seqüência da vinificação, o mosto passa pelas fermentações alcoólica e malolática. Do conjunto de reações que ocorrem nessa fase, nasce o aroma...

Churchill County, Nevada had approximately 23,000 residents, with an estimated 13,500 who relied on private wells for water supply in 2002.  This study examined exposure to arsenic in water supplies among residents with private domestic wells and factors related to householder choice to consume tap water.  It compared opinions and concerns about water quality with consumption habits and observed concentrations from tap water samples. The results from 351 households indicated that a majority (75%) of respondents consumed tap water and that a minority (38%) applied treatment.  Approximately 66% of those who consumed tap water were exposed to concentrations of arsenic that exceeded 10 ppb.  Water consumption was related to application of treatment.  Among 98...

Arsenic phytoextraction and hyperaccumulation by fern species
Provedor de dados: 63
Autores: Gonzaga,Maria Isidoria Silva; Santos,Jorge Antonio Gonzaga; Ma,Lena Qiying.
Arsenic (As) is an ubiquitous trace metalloid found in all environmental media. Its presence at elevated concentrations in soils derives from both anthropogenic and natural inputs. Arsenic is a toxic and carcinogenic element, which has caused severe environmental and health problem worldwide. Technologies currently available for the remediation of arsenic-contaminated sites are expensive, environmentally disruptive, and potentially hazardous to workers. Phytoextraction, a strategy of phytoremediation, uses plants to clean up contaminated soils and has been successfully applied to arsenic contaminated soils. It has the advantage of being cost-effective and environmentally friendly. A major step towards the development of phytoextraction of arsenic-impacted...

Nasopharyngeal carcinoma (NPC) is notorious for the metastases, which are in close association with Epstein-Barr virus-encoded latent membrane protein 1 (LMP1). Arsenic trioxide (As2O3) has been shown to induce apoptosis and differentiation in NPC xenografts. Then, can it repress the cancer cells' metastasis potential? To elucidate this issue, the present study was performed. LMP1-negative cell line HNE1 and LMP1-positive cell line HNE1-LMP1 were used as in vitro model. Cells (1 x 10(5)/mL) were cultured with or without 3 µM As2O3 for 48 h. Then the survival cells were collected to investigate their potential of colony formation, attachment, invasion, and migration. Both confocal immunofluorescence staining and Western blot were used to detect the changes...

Los productos que de ella se obtienen juegan un importante papel en la dieta humana como fuente de proteína animal, minerales y ácidos grasos esenciales, entre otros. La inmensidad del océano y su biodiversidad, dio lugar por mucho tiempo a la creencia de que el mar era una fuente ilimitada de recursos, capaz de sustentar la población humana indefinidamente. Nada parecía alertar sobre la necesidad de usar métodos de pesca racionales, ni sobre las serias consecuencias ambientales que puede conllevar la actividad pesquera. El perfeccionamiento de buques pesqueros y de las técnicas de navegación determinó un explosivo crecimiento de la...

Arthropods associated with the crown of Mauritia flexuosa (Arecaceae) palm trees in three different environments from Brazilian Cerrado
Provedor de dados: 82
Autores: Gurgel-Gonçalves,Rodrigo; Palma,Alexandre R.T.; Motta,Paulo C.; Bar,Maria E.; Cuba,Cesar A.C.
Canopy arthropods, mainly from palm trees, are little known in the Brazilian Cerrado. In order to describe the arthropod community structure associated with the crown of Mauritia flexuosa (Arecaceae), we sampled 150 palm trees in six "veredas" of the Federal District, Brazil, in wild, rural and periurban areas in the rainy season. The arthropods within abandoned bird nests, mammal refuges, leaves and organic matter were manually collected, preserved in ethanol 70% and separated by order, family, morphospecies and feeding guilds. Stem height and diameter of the palm crowns were measured and leaves and bird nests were counted. We collected 3,862 arthropods, from 15 orders, 45 families and 135 morphospecies. The most abundant orders were Coleoptera (28.6%),...

O objetivo deste trabalho foi avaliar o efeito de três leguminosas arbóreas sobre a densidade e a diversidade de macrofauna de um Argissolo Vermelho-Amarelo, de baixa fertilidade natural. Duas espécies fixadoras de nitrogênio atmosférico, a orelha-de-negro (Enterolobium contortisiliquum) e o jacarandá-da-baía (Dalbergia nigra), e uma não-fixadora, o angico-canjiquinha (Peltophorum dubium), foram consorciadas em pastagem de capim survenola (híbrido interespecífico entre Digitaria setivalva e Digitaria valida), tendo por testemunha pasto a pleno sol. Formicidae foi o grupo mais abundante em todos os tratamentos, sendo seguido por Oligochaeta, com 47% nos tratamentos com leguminosas e 23% no pasto a pleno sol. Os maiores valores em diversidade de fauna foram...

As aves da Reserva Florestal do Morro Grande (Cotia, SP)
Provedor de dados: 49
Autores: Develey,Pedro F.; Martensen,Alexandre Camargo.
Um total de 198 espécies de aves foi registrado na Reserva Florestal do Morro Grande. O levantamento foi realizado entre os anos de 2001 e 2003, utilizando-se métodos de amostragem qualitativos e quantitativos (redes de neblina e pontos fixos). O número de espécies registrado através dos métodos quantitativos foi menor do que o número total de aves presentes na Reserva, sendo 98 espécies registradas nos pontos fixos e 46 nas redes de neblina. Apesar das diferenças, os dois métodos se mostraram eficientes na detecção de padrões de distribuição das aves. Existe uma grande heterogeneidade da avifauna na Reserva, sendo que as diferenças mais marcantes são entre os trechos de matas primárias e secundárias. As matas primárias são mais ricas e apresentam muitas...

As formigas como indicadores biológicos do impacto humano em manguezais da costa sudeste da Bahia
Provedor de dados: 82
Autores: Delabie,Jacques H.C.; Paim,Valéria R.L. de M.; Nascimento,Ivan C. do; Campiolo,Sofia; Mariano,Cléa dos S.F.
Os manguezais são comuns ao longo dos estuários da costa Atlântica do Brasil. Embora a diversidade de plantas seja baixa, esse ecossistema suporta uma fauna diversa, oferecendo diferentes tipos de recursos para numerosos organismos não aquáticos. Muitos insetos habitam as áreas de manguezal e, entre estes, numerosas espécies de formigas exclusivamente arbóreas. Na maior parte das áreas do mundo onde ocorrem, os manguezais vêm sofrendo altos níveis de impacto humano e isso é particularmente evidente no Sudeste da Bahia, onde ocorre o tradicional extrativismo de caranguejos e peixes, aterramento com fim de exploração imobiliária e corte de lenha. A comunidade de formigas de 13 manguezais com diferentes níveis de antropização foi estudada na costa sudeste da...

Ascaris suum infections in pigs born and raised on contaminated paddocks
Provedor de dados: 21
Autores: Mejer, Helena; Roepstorff, Allan.
The transmission of Ascaris suum was studied in outdoor reared pigs. From May to June, 2001 6 farrowing paddocks were naturally contaminated with A. suum using experimentally infected seeder pigs. Early July, 1 sow farrowed on each paddock. One piglet per litter was slaughtered every second week starting week 3 post partum (p.p.) for registration of liver white spots and recovery of A. suum from the lungs and the small intestine. The last pigs were slaughtered week 19 p.p. Faeces was examined for eggs and blood was analysed for A. suum specific antibodies. Weaning took place week 7 p.p. by removing the sow. Paddock infection levels were estimated by regular examination of soil samples and in late June and late November using parasite naïve tracer pigs....

Ascenso hidráulico en y entre isletas de vegetación en la zona árida de Argentina
Provedor de dados: 85
Autores: Bonvissuto,GL; Busso,CA.
Este estudio se llevó a cabo en el Monte Austral Neuquino (MAN), Provincia de Neuquén, Argentina (39o20' S; 69o19' O). La vegetación está distribuida sobre la superficie del suelo como isletas de vegetación. En el suelo de éstas isletas se pueden observar dos lugares superficiales muy contrastantes: ubicación1, debajo del follaje de las principales gramíneas perennes y arbustos más altos, y ubicación2, que incluye los corredores descubiertos de vegetación entre los parches vegetados. La hipótesis de éste trabajo fue que el fenómeno de ascenso hidráulico es de mayor magnitud debajo que entre isletas de vegetación en el MAN. Con este propósito, en cada una de dos isletas de vegetación se colocaron psicrómetros a termocupla debajo de los arbustos y en los...

Autores: Sampaio,R.L.; Ranzani,J.J.T.; Rodrigues Júnior,V.; Stacciarini,M.S.; Braga,E.M.; Borrezzi,C.
Avaliaram-se, por meio da análise clínica, histopatologia e imunoistoquímica, os efeitos da aplicação da membrana amniótica xenógena fresca e conservada em glicerina, sobre os mecanismos imunológicos da superfície ocular. Para tal, utilizaram-se 40 coelhos, distribuídos em dois grupos experimentais, os quais foram avaliados por 21 dias. A avaliação clínica revelou que a membrana amniótica xenógena conservada em glicerina estimulou uma resposta inflamatória aguda maior que a membrana aplicada fresca. A análise histopatológica indicou que ambas se comportaram de forma semelhante a partir da primeira semana de pós-operatório, apresentando as alterações clássicas da resposta inflamatória da córnea, com o predomínio de infiltrado do tipo polimorfonuclear.

Autores: Mazzoni,Rosana; Silva,Anna P. F. da.
Aspectos da história de vida de Bryconamericus microcephalus (Miranda Ribeiro, 1908) do córrego Andorinha (23º11'12"S, 44º12'02"W) foram analisados pela descrição da estrutura de tamanho, relação peso-comprimento e estratégia reprodutiva. Os exemplares estudados foram obtidos bimestralmente, por redes de espera e "picarés" (malhas entre 0,5 e 1,0 cm) entre novembro de 1999 e setembro de 2003. A estrutura de tamanho indicou que as fêmeas alcançaram maiores tamanhos que os machos e que ocorreram maior número de fêmeas nas classes de tamanho superiores a 5,3 cm. A relação peso-comprimento mostrou-se significativamente diferente entre os sexos e indicou que, para uma mesma classe de tamanho, as fêmeas foram mais pesadas que os machos. A proporção sexual foi de...

Aspectos fisiopatológicos da retenção de ovos em Jabutipiranga (Geochelone carbonaria Spix, 1824)
Provedor de dados: 65
Autores: Matias,Carlos Alexandre Rey; Romão,Mário Antônio Pinto; Tortelly,Rogério; Bruno,Sávio Freire.
Das enfermidades que acometem o sistema genital de répteis, a retenção de ovos tem grande prevalência em quelônios. Neste trabalho, são analisados quatorze casos de retenção de ovos na espécie jabutipiranga (Geochelone carbonaria Spix, 1824), mantidos como animais de companhia, os quais foram atendidos na Policlínica Veterinária da Universidade Federal Fluminense (UFF) entre os anos de 1999 e 2003. Dos fatores que provocam ou favorecem a ocorrência dessa distocia, foram avaliados: em relação aos ovos retidos, a presença de ovos com alterações de formato e de tamanho aumentado e hipercalcificação das cascas; em relação aos fatores predisponentes, foram analisados fatores ambientais, sinais nos pacientes relacionados à ocorrência de doença osteometabólica,...

Aspectos genético-quantitativos da qualidade da carne em frangos
Provedor de dados: 65
Autores: Gaya,Leila de Genova; Ferraz,José Bento Sterman.
O estudo dos parâmetros genéticos das características de qualidade de carne de aves permite à industria avícola se adequar às exigências da indústria processadora, aumentando sua eficiência, e melhorando a aceitação da carne de frango pelo mercado consumidor. Além disso, por meio do estudo destes parâmetros, valiosas informações sobre a caracterização do fenômeno denominado PSE, que representa a carne pálida, flácida e exsudativa, podem ser obtidas, uma vez que são escassos os estudos a esse respeito em frangos. O conhecimento do comportamento genético e da relação entre os atributos da carne e outras características de interesse em frangos de corte pode favorecer o estabelecimento mais preciso e adequado das estratégias utilizadas nos programas de seleção.

ABSTRACT: Despite of all modem communications tools, difficulties of dialogue still exist between technicians and local community members when dealing with natural resources. This is related to many factors, from the predominantly technical formation of the teachers and researches to the difficult of local population members to be understood about their relationship with the surrounding environment. In the case of Soil Science, this problem also occurs. Proposals for planning soil sustainable usage, usually, are compromised because the do not consider the local knowledge, especially in rural communities, where there is no basic material compatible to the work scale needed. The approach of observing the environment and how humans interact with it, from the...

Aspectos práticos da suplementação alimentar de bovinos de corte.
Provedor de dados: 14
Autores: THIAGO, L. R. L. de S.; SILVA, J. M. da.
Para ser competitiva, a bovinocultura de corte tropical precisa explorar melhor o pasto, corrigindo, quando necessário, possíveis deficiências nutricionais, isto com muito critério e dentro de uma meta de produção bem estabelecida. Nos trópicos, ao contrário dos países de clima temperado, é possível manter os bovinos em pastejo durante todo o ano, maximizando o conceito do ?boi verde? e preservando as características digestivas do animal ruminante. Tal conceito envolve inúmeros fatores: a energia solar (luz e calor), a planta forrageira (componente sintetizador das substâncias orgânicas via fotossíntese), os bovinos (componente transformador da matéria vegetal em carne/leite por fermentação ruminal), o solo (componente sustentador e fornecedor de elementos...

Aspects of phosphorous fertilisation in organic farming
Provedor de dados: 21
Autores: Schnug, E; Haneklaus, S; Kratz, S; Fan, X.
Balanced fertilisation is essential for a considerate use of limited phosphorus (P) resources and for sustainability in organic farming. Plant available soil P levels will decrease and soil fertility will diminish when using P sources with limited P availability such as rock phosphates, bone and bone meals. An in situ digestion with a combination product of elemental S and rock phosphate enhanced significantly the solubility of non water-soluble P sources. In addition to the problem of insufficient solubility, mineral P sources can be contaminated with toxic heavy metals such as Cd  0.1–92.3 mg kg-1) and U (&lt;LLD - 481 mg kg-1) from their source. Farmyard manure and slurry may contain up to 953/727 and 376/132 mg kg-1 Zn and Cu, respectively.

Provedor de dados: 21
Autores: Döring, Thomas F.; Heimbach, Udo; Thieme, Thomas; Saucke, Helmut.
In Praxisversuchen wurde über drei Jahre der Einfluss von Strohmulch auf das Auftreten von PVY (Potato virus Y), den Befall mit dem Kartoffelkäfer (Leptinotarsa decemlineata) und den Knollenertrag in ökologisch angebauten Kartoffeln untersucht. Strohmulch führte in drei von 17 Experimenten zu einer signifikanten Reduktion von PVY, und in weiteren sieben Versuchen gab es einen nicht-signifikanten Trend zur erminderung von PVY. Der Effekt von Strohmulch auf PVY scheint vom allgemeinen Infektionsniveau abzuhängen, welches je nach Jahr, Standort und Sorte unterschiedlich war. So gab es in den Jahren 2002 und 2004 bei allgemein hohem Infektionsdruck eine konsistente PVY-Verminderung. Im Gegensatz dazu konnte im Jahr 2003, bei nur sehr geringem Infektionsdruck,...

A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of São Paulo. Sixty-four endophagous species of Diptera and Lepidoptera were recorded from 49 asteracean host plants. Approximately half of the species were obtained from a single locality, with a large proportion emerging from a single sample (unicates). Thirty percent of the species were singletons (i.e. only one individual was recorded). The large proportion of rare species suggests a high species turnover among localities. Lepidopteran species were recorded on more host species than dipterans, confirming their more polyphagous food habit, also observed in other Brazilian biomes...

The objectives of this study are (i) to assess consumer perceptions on fresh milk that are stored in tetra-packs, and (ii) to determine the relationship between the perceptions and the socio-economic characteristics of the consumers. Using Caswell's four subsets of food quality (i.e. food safety, nutrition, value, and packaging) two indices, namely Mean Attribute Score (MAS) and a Food Quality Responsive Index (FQRI) were developed, which describe how important each of these four subsets and various attributes included in each subset for a consumer to be "loyal" with fresh milk in a tetra-pack instead of spending that part of money on close substitutes. A sample of 664 consumers were randomly selected and interviewed using a structured questionnaire at 10...

Within a context of global trade liberalisation and constrained national budgets, agriculture in many countries has proved incapable of sustaining household livelihoods an d socio-economic development in rural areas. The post-war industrial success of several Asian countries has suggested various alternatives for rural development, including tourism for domestic and possibly foreign visitors. After outlining the economic characteristics of rural tourism and its policies, this paper reviews the evolution of government policies in this area in East Asia, including the establishment of "tourist farms" and "pilot scheme" villages in Korea since the 1980s.

Assessing impacts of CAP reform in France and Germany
Provedor de dados: 31
Autores: Kupker,   Bernd; Huttel,   Silke; Kleinhanss,   Werner; Offermann,   Frank.
The 2003 CAP Reform left EU member states much room for national implementation. The farm group model EU-FARMIS is applied to quantify the effects of the reform and the impacts of the options for national implementation. The analysis is done for France and Germany because their implementation schemes adequately reflect the broad range of options. It is found that cereal and fodder maize production is reduced both in France and Germany. In contrast, the acreage of other arable fodder crops, of set-aside and of non-food crops is expanded. While bull fattening is substantially reduced in both countries, suckler cow production is extended in France due to partial decoupling, but reduced in Germany due to full decoupling. Sectoral income effects measured in...

The ecological status of lake Pyhäjärvi, located in south-western Finland, may be classified as moderate due to its elevated nutrient concentrations and algal biomass production. Thus, the Yläneenjoki river basin, accounting for &gt;50% of the total phosphorus loading to the lake, was chosen as the Finnish test catchment in the Benchmark models for the Water Framework Directive project. One aim of the project was to test the suitability of models like the catchment scale model SWAT for the assessment of nutrient and sediment transport and management options needed to meet the surface water quality requirements.

Assessing potential impact of avian influenza on poultry in West Africa: a spatial equilibrium model analysis
Provedor de dados: 31
Autores: You,   Liangzhi; Diao,   Xinshen.
In this paper, the authors analyze the potential economic impacts of avian influenza (AI) in West Africa, taking Nigeria as an example. They find that, depending on the size of the affected areas, the direct impact of the spread of AI along the two major migratory bird flyways would be the loss of about 4 percent of national chicken production. However, the indirect effect-consumers’ reluctance to consume poultry if AI is detected, causing a decline in chicken prices-is generally larger than the direct effect. The study estimates that Nigerian chicken production would fall by 21 percent and chicken farmers would lose US$250 million of revenue if the worst-case scenario occurred. The negative impact of AI would be unevenly distributed in the country, and...

Assessing Risks to Wildlife Populations from Multiple Stressors: Overview of the Problem and Research Needs.
Provedor de dados: 7
Autores: Munns, Jr., Wayne R.; U.S. Environmental Protection Agency; munns.wayne@epa.gov.
Wildlife populations are experiencing increasing pressure from human-induced changes in the landscape. Stressors including agricultural and urban land use, introduced invasive and exotic species, nutrient enrichment, direct human disturbance, and toxic chemicals directly or indirectly influence the quality and quantity of habitat used by terrestrial and aquatic wildlife. Governmental agencies such as the U.S. Environmental Protection Agency are required to assess risks to wildlife populations, in its broadest definition, that result from exposure to these stressors, yet considerable uncertainty exists with respect to how such assessments should be conducted. This uncertainty is compounded by questions concerning the interactive effects of co-occurring...

Assessing the 2003 CAP Reform: Sensitivity to the Decoupling of Agenda 2000 Direct Payments
Provedor de dados: 31
Autores: Gohin,   Alexandre.
The European Union decided in June 2003 a new reform of its farm policy with a new step toward the decoupling of farm income support instruments. Available impact studies find that this reform will reduce production incentives, substantially for beef and to a lesser extent for arable crops. All these studies assume that the Agenda 2000 arable crop direct payments are already mostly decoupled while beef premiums are much more linked to production. Our main objective in this paper is to test the sensitivity of these results to this questionable modelling of Agenda 2000 direct payments which neglects eligibility rules and land market imperfections. Our analysis reveals that the negative effects of the reform on both arable crop and beef production are not...

Assessing the Distributional Impacts of Transferable Pollution Permits: The Case of Phosphorus Pollution Management at a River Basin Scale
Provedor de dados: 31
Autores: Kampas,   Athanasios; Mamalis,   Spyridon.
Although the initial allocation of pollution permits is neutral in terms of efficiency, it does have a significant impact on distributive equity. In this paper, we examine the two main categories of permit allocation rules, the distributive and the reductive, for controlling phosphorus pollution in a small catchment in South West England. Based on the premise that the regulatory choice compromises efficiency and equity, the main result of this paper is that an allocation of permits in proportion to the intensity of environmental preferences is a “win-win” choice. The reason is that it simultaneously achieves two goals. First, it is efficient (or cost-effective) since a permit system achieves a prespecified target at a minimum abatement cost, while second,...

Assessing the effects of marine protected area (MPA) on a reef fish assemblage in a northwestern Mediterranean marine reserve: Identifying community-based indicators
Provedor de dados: 5
Autores: Claudet, Joachim; Pelletier, Dominique; Jouvenel, J.y; Bachet, F; Galzin, R.
Marine protected areas (MPAs) are increasingly envisaged as a tool to manage coastal ecosystems and fisheries. Assessment of their performance with respect to management objectives is therefore important. A number of WAS provided conservation benefits for fished species. Observed benefits do not apply to all species at all times, and responses to protection are also highly variable among fish taxa. Among the many empirical studies on marine reserves, only a few designs considered 'before and after data' and spatial variation. In this paper, we are interested in assessing the effect of a no-take reserve on the reef fish assemblage in a northwestern Mediterranean example. Data were obtained from a three-year survey using underwater visual censuses (UVC),...

In this paper, we present an approach to compare the impact of different management options oil the dynamics of a mixed fishery. We used ISIS-Fish, a simulation tool aimed at evaluating the impact of spatial and seasonal management measures on the dynamics of mixed fisheries. The French Nephrops norvegicus (Norway lobster) Merluccius merluccius (hake) mixed fishery of the Bay of Biscay was chosen as a Study case. First, we parameterised the Population and exploitation models. We then selected several management measures, including marine protected fishermen's reaction to each measure. Then, a sensitivity analysis (MPAs) and total allowable catches (TAC), and parameterised fish sensitivity analysis was performed according to a fractional factorial...

Assessing the Impact of International Natural Resource Management Research: The Case of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: 31
Autores: Laxmi,   Vijay; Erenstein,   Olaf.
A conservative ex-ante assessment of supply-shift gains alone (excluding social and environmental gains), shows that the investment in zero tillage (ZT) R&amp;D by the Rice-Wheat Consortium and CIMMYT was highly beneficial with a benefit-cost ratio of 39, a net present value of US$ 94 million and an internal rate of return 57%. Sensitivity analysis highlights the influential role of the yield gain, the contribution of reduced tillage (i.e. partial adoption) and the assumed time-lag. Significant positive spillovers of sunk ZT R&amp;D costs – both previous and from elsewhere - also contributed to the high returns. The case thereby highlights the potential gains from successful technology transfer and adaptation. The case however also underscores that...

Assessing the Impact of Stricter Food Safety Standards on Trade: HACCP in U.S. Seafood Trade with the Developing World
Provedor de dados: 31
Autores: Anders,   Sven M.; Caswell,   Julie A.
Health risks associated with seafood products prompted the introduction of mandatory HACCP in the seafood industry in the United States in 1997. This paper quantifies the trade impact of this introduction by analyzing patterns of seafood imports to the U.S. over the period 1990 to 2004. The results of a gravity model using panel data suggest that HACCP had a negative and significant impact on overall seafood imports from the top 33 developing and developed countries selling into the U.S. For developing countries, the results support the view of “"standards-as-barriers"” versus "”standards-as-catalysts"” as the negative HACCP effect was experienced by developing countries, while the effect for developed countries was positive.

Assessing the potential of organic farming for sustainable  livelihoods in developing countries - The case of cotton in India
Provedor de dados: 21
Autores: Eyhorn, Frank.
Based on the example of cotton farming in India, this research examines in how far conversion to organic management can be a viable option for improving the livelihoods of farmers in developing countries. While cotton cultivation provides livelihood for an estimated 10 million Indian households, stagnating cotton yields, high input costs and low cotton prices have led many of them into indebtedness. By substituting synthetic fertilizers and pesticides with farm-own resources and labour, organic farming not only could have the potential to improve natural resource management, but also to reduce production costs and obtain a better price for the produce. Development agencies and companies are increasingly trying to utilize this potential by organizing...

It is widely assumed that the scenic attractiveness and other public good aspects of agricultural land can be utilized as a source of livelihood in rural areas in the form of recreation and tourism. In this study we use two approaches to consider whether agricultural landscapes are preferred as a destination for recreation (day trips) and rural tourism (overnight trips). We first analyse the choice of recreation site type based on a model that aggregates sites using the presence of agricultural land as an aggregation variable. Population survey data on recreation trips reveal an association between the respondent’s living environment, recreational activities and visit characteristics and the probability of choosing a destination with agricultural land....

ASSESSING THE RESPONSE OF FARM HOUSEHOLDS TO DAIRY POLICY REFORM IN ISRAEL
Provedor de dados: 31
Autores: Kimhi,   Ayal; Rubin,   Ofir D.
After nearly fifty years of stability and stagnation of dairy market regulations in Israel, a dramatic policy reform has been enacted in 1999. The reform enabled farm households, for the first time, to trade production quotas. In addition, the reform signaled to farmers that milk prices will gradually go down in real terms, and therefore only producers who expand and become more efficient will prevail. The reform allowed for generous financial support for investment in expansion, but also required the adoption of environmental regulations which could be costly to many farm families. This paper uses data from a census of small family-operated dairy enterprises that was conducted in 2001, in order to analyze the response of farm households to the reform. The...

Assessing the Risk of Oil Spills in the Mediterranean: the Case of the Route from the Black Sea to Italy

Autores: Bigano,   Andrea; Sheehan,   Paul.
Recent major spills on European coasts have highlighted the primary policy relevance for the EU of oil spills. This paper assesses the risks related to carrying oil to the EU along the route from the Russian Black Sea coast to Sicily, Italy (one of the most congested and strategically relevant European import routes). We develop a methodology based on Fault Tree Analysis, and we apply it to the most likely causes of an oil spill. We couple the resulting probabilities with data on expected spill size, types of oil carried and cleanup costs, to estimate expected costs for cleanup and loss of cargo. The route analysed appears to be a risky one; there is a “high” to “very high” risk of a spill along this route. The Turkish Straits turn out to be the major...

We propose an information-theoretic approach to assess the performance of a discrete choice model used to analyze land use and land use change. We show that our disaggregated measure can be used to compare robustness of predictions across land use categories and across models. Furthermore, a proper reformulation of the problem shows that a disaggregated (observation by observation) log-likelihood lends itself to an information theoretic interpretation, which allows comparisons performance across models.

Assessment of nitrogen flows into the Cuban landscape
Provedor de dados: 20
Autores: Baisre, J. A.
The alteration of the nitrogen (N) cycle by human activities is widespread and has often resulted in increased flows of nitrogen to the marine environment. In this paper we have attempted to know the changes of N fluxes in Cuba by quantifying the N inputs to the landscape from (1) fertilizer applications, (2) atmospheric deposition, (3) biological nitrogen fixation and (4) net import of food and feeds. N-inputs to the country progressively increased until the end of the 20th century, reaching a peak during the 80s when low cost fertilizer imported from the former Soviet Union led to heavy rates of application. This rapid growth represented more than a 5-fold increase with respect to pristine values; higher than the two-fold global increase of anthropogenic...

Proso millet (Panicum miliaceum L.) is a serious weed in North America. A high number of wild proso millet biotypes are known but the genetic basis of its phenotypic variation is poorly understood. In the present study, a non-radioactive silver staining method for PCR-Amplified Fragment Length Polymorphism (AFLP) was evaluated for studying genetic polymorphism in American proso millet biotypes. Twelve biotypes and eight primer combinations with two/three and three/three selective nucleotides were used. Pair of primers with two/three selective nucleotides produced the highest number of amplified DNA fragments, while pair of primers with three/three selective nucleotides were more effective for revealing more polymorphic DNA fragments. The two better primer...

Assessment of the exposure pathway in the uptake and distribution of americium and cesium in cuttlefish (Sepia officinalis) at different stages of its life cycle
Provedor de dados: 5
Autores: Bustamante, Paco; Teissier, J.l; Warnau, M.
Laboratory radiotracer experiments were performed to study the uptake, assimilation and retention of americium (241Am) and cesium (134Cs) by the common cuttlefish Sepia officinalis. Uptake and loss kinetics of the radionuclides were measured following exposure through sediments, seawater and food at different stages of the animal's life cycle. Sediment was found to be a minor uptake pathway for both radionuclides in juveniles. Following a short seawater exposure, cuttlefish accumulated 241Am and 134Cs, but only to a limited extent (whole-body CF &lt; 2). Among the cuttlefish organs, branchial hearts and their appendages displayed the highest degree of uptake for 241Am (CF = 42 and 16, respectively), but these tissues contained low percentage of total 241Am...

Autores: Covolan,L.; Mello,L.E.
Pilocarpine-induced (320 mg/kg, ip) status epilepticus (SE) in adult (2-3 months) male Wistar rats results in extensive neuronal damage in limbic structures. Here we investigated whether the induction of a second SE (N = 6) would generate damage and cell loss similar to that seen after a first SE (N = 9). Counts of silver-stained (indicative of cell damage) cells, using the Gallyas argyrophil III method, revealed a markedly lower neuronal injury in animals submitted to re-induction of SE compared to rats exposed to a single episode of pilocarpine-induced SE. This effect could be explained as follows: 1) the first SE removes the vulnerable cells, leaving behind resistant cells that are not affected by the second SE; 2) the first SE confers increased...

Our study aims at making progress the estimate of herbicide and nutrient inputs to the Marennes-Oleron bay which could influence summer oysters mortalities, and to bring, a better understanding of the impact on coastal ecosystems by modelling the dynamics of these compounds in the shellfish-farming area. The development of a strategy adapted to the river Charente and its estuary reveals that agricultural activity on the watershed area is omnipresent, as well on the level of the nitrogen as on the one of herbicides contributions. It is thus necessary to specify Charente fluxes, which is the main tributary of the Marennes-Oleron bay, in order to better characterize its impact on shell fish-farming activity. Hydrodynamic modelling will constitute an...

The study presents assessment of an operational wave model (Wavewatch III), focusing upon the model sensitivity to wind-forcing products. Four wind fields are used to drive the model, including the NCEP/NCAR reanalysis and three other products that assimilate various satellite wind measurements having high spatial resolution, including the QuikSCAT scatterometer. Three wave field statistics: significant wave height, mean zero-crossing wave period, and mean square slope are compared with collocated TOPEX altimeter derivatives to gauge the relative skill of differing wind-forced model runs, as well as to demonstrate an extended use of the altimeter beyond simply supplying wave height for wave model validation and assimilation.

Asset Utilization and Bias in Measures of U.S. Agricultural Productivity
Provedor de dados: 31
Autores: Alston,   Julian M.; Andersen,   Matthew A.; Pardey,   Philip G.
A common observation is that measures of productivity growth are pro-cyclical, meaning they are higher (or grow faster) on average during periods of economic expansion than during periods of economic contraction. This study focuses on measurement errors related to capital inputs as an explanation for the existence of pro-cyclical patterns in measures of agricultural productivity.  Calculating a time series of capital inputs is difficult and prone to errors.  Myriad assumptions are required to construct a typical measure of the capital stock, and further, sometimes related, assumptions must be made about the utilization of the stock to derive a measure of capital service flows.  We test the hypothesis that unmeasured changes in the utilization of capital...

Nicotine exposure is a risk factor in several breathing disorders Nicotinic acetylcholine receptors (nAChRs) exist in the ventrolateral medulla, an important site for respiratory control. We examined the effects of nicotinic acetylcholine neurotransmission on central respiratory control by addition of a nAChR agonist or one of various antagonists into superfusion medium in the isolated brainstem-spinal cord from neonatal rats. Ventral C4 neuronal activity was monitored as central respiratory output, and activities of respiratory neurons in the ventrolateral medulla were recorded in whole-cell configuration. RJR-2403 (0.1-10mM), alpha4beta2 nAChR agonist induced dose-dependent increases in respiratory frequency. Non-selective nAChR antagonist mecamylamine...

The effect of the bovine major histocompatibility complex (BoLA) locus on animal health may be due to a direct action of its alleles on immune functions, whereas its indirect effect on production traits might be explained by the better general health conditions of more productive animals. In the present study, the BoLA-DRB3 gene was investigated in 1058 cows belonging to seven Brazilian Gyr Dairy herds (Bos indicus, Zebu cattle). A total of 37 alleles were identified, 15 of them described for the first time in a Zebu breed. A highly significant association (p &lt; 0.02) was observed between allele *54 and a decrease (-26.1 kg) in milk protein yield and there was a significant association (p &lt; 0.05) between this allele and lower (-26.07 kg) milk fat...

Provedor de dados: 74
Autores: Santana,Bárbara Amélia Aparecida; Biase,Fernando H.; Antunes,Robson Carlos; Borges,Mauricio; Franco,Mauricio Machaim; Goulart,Luiz Ricardo.
Estrogen has an important function in swine reproduction and growth. A Pvu II restriction enzyme polymorphism has been proven to be an important genetic variation in the estrogen receptor gene (ESR) and may be considered as a candidate gene for use in pig production but there is no data regarding the prevalence of this polymorphism in the Brazilian pig population. We used DNA samples from the following three purebred pig breeds: Large White (336 females and 26 males), Landrace (304 females and 27 males) and Pietrain (125 females and 11 males). The ESR genotyping was performed using PCR-RFLP. For each breed, genotypes for the ESR gene were compared independently for expected progeny differences (EPD) in litter size (LS), average daily weight gain (DWG)...

Autores: Chatelier, Aurelien; Mckenzie, David; Prinet, Aurelie; Galois, Robert; Robin, Jean; Zambonino, Jose-luis; Claireaux, Guy.
Seabass were fed for 4 months with diets where the lipid was provided as either canola oil (CO), palm oil ( PO) or fish oil (FO), to generate diversity in their tissue fatty acid (FA) composition and investigate how this influenced major traits of exercise performance, cardiac performance and respiratory metabolism. In particular, based upon previous observations, we investigated the hypothesis that enriching the fish tissues with oleic and linoleic acids (OA, 18:1n-9 and LA, 18:2n-6, respectively) from the CO and PO diets would improve maximum exercise and cardiac performance, and increase aerobic metabolic scope. This proved to be the case; exercise respirometry on bass fitted with cardiac flow probes revealed that those fed CO and PO diets had a...

Autores: Cresoni-Pereira,Carla; Zucoloto,Fernando S.
The aim of the present study was to determine whether wild adult Anastrepha obliqua (Macquart, 1835) females are able to associate a compound (quinine sulphate - QS) not related to their habitual diet with a protein-enriched food. Females were first fed on diets based on brewer yeast and sucrose containing or not QS. The groups were then allowed to choose between their original diets and a diet with or without QS, depending on the previous treatment, and between a diet based on agar and a diet containing agar and QS. When the nutritional value of the diets was adequate, the females did not show any preference for the diet with or without QS. With respect to the agar diet and the agar + QS diet, females previously fed on a nutritive diet containing QS...

Provedor de dados: 83
Autores: Artoni,Roberto Ferreira; Shibatta,Oscar Akio; Gross,Maria Claudia; Schneider,Carlos Henrique; Almeida,Mara Cristina de; Vicari,Marcelo Ricardo; Bertollo,Luiz Antonio Carlos.
Four populations of Astyanax aff. fasciatus of the upper rio Tibagi (municipal district of Ponta Grossa, Paraná State, Brazil), had their karyotypes and morphometry analyzed. The cytogenetic data show the occurrence of distinct karyotypes (cytotypes), here named cytotype A, with 2n=48 chromosomes (6m+18sm+14st+10a), cytotype B, with 2n=50 chromosomes (8m+18sm+14st+10a) and cytotype C, with 2n=50 chromosomes (8m+18sm+14st+10a). The distribution pattern of the constitutive heterochromatin was very similar between cytotypes A and B, but diverged in relation to cytotype C. Distinct cytotypes may occur in sympatry in the upper rio Tibagi region, with the exception of the Furna 2 sample, which presents cytotype A exclusively. In addition, a specimen with 2n=49...

Asymmetric property rights in China's economic growth
Provedor de dados: 31
Autores: Zhang,   Xiaobo.
This paper highlights the difference between secure investor property rights and loosely defined individual property rights. Globalization and fiscal decentralization have intensified this difference. On the one hand, in the presence of mobile foreign direct investments and under the arrangement of fiscal decentralization, local governments compete vigorously to offer various protections on the property rights of investors; on the other hand, local governments and developers attempt to acquire land at as low price as possible by taking advantage of the loopholes inherent in the Chinese law. Secure investor property rights together with weak protections on individuals’ land property rights is argued to be one of the major drivers of China’s rapid economic...

Autores: Jalonoja,   Kati; Liu,   Xing; Pietola,   Kyosti.
This paper estimates market integration between the Finnish and German pork and beef markets. An econometric error correction model that allows for threshold effects and asymmetric price response is estimated. The data are weekly price observations during the period of 1995-2004. Each price series have 520 observations. The results suggest that the Finnish beef prices are stationary and they are not co-integrated with the German price. Thus, the domestic and imported beef may be treated as different goods by consumers. The pork prices are integrated of the first order I(1) and they are also co-integrated. The threshold effects are significant and the price adjustment process is asymmetric, but slow in all regimes. The price transmission process has...

Acute promyelocytic leukemia (APL) is characterized by the expansion of blasts that resemble morphologically promyelocytes and harbor a chromosomal translocation involving the retinoic acid receptor a (RARa) and the promyelocytic leukemia (PML) genes on chromosomes 17 and 15, respectively. The expression of the PML/RARa fusion gene is essential for APL genesis. In fact, transgenic mice (TM) expressing PML/RARa develop a form of leukemia that mimics the hematological findings of human APL. Leukemia is diagnosed after a long latency (approximately 12 months) during which no hematological abnormality is detected in peripheral blood (pre-leukemic phase). In humans, immunophenotypic analysis of APL blasts revealed distinct features; however, the precise...

Avaliou-se a ativação de plaquetas em 20 eqüinos com laminite induzida, tratados com ketoprofeno, fenilbutazona e flunixin meglumina. As alterações de plaquetas incluíram mudança de forma, alteração da relação entre os eixos maior e menor, aumento de perímetro, emissão de pseudópodes, aumento no número dealfa-grânulos e de grânulos de glicogênio e redução no número degama-grânulos. As plaquetas de eqüinos, quando ativadas, apresentaram perfil de organela diferente de plaquetas normais, e as drogas antiinflamatórias, não-esteroidais, demonstraram atividade na ativação plaquetária de eqüinos in vivo. O flunixin meglumina apresentou melhor atividade em modular a ativação plaquetária de eqüinos in vivo do que a fenilbutazona e o ketoprofeno.

As propriedades biológicas da própolis de Apis mellifera são amplamente relatadas sendo comuns variações nas mesmas em função da região onde foram produzidas. A ação antimicrobiana de própolis obtidas em três regiões do Brasil (Botucatu-SP, Mossoró-RN e Urubici-SC) foi investigada sobre linhagens isoladas de infecções clínicas humanas (Staphylococcus aureus, Escherichia coli, Enterococcus sp, Pseudomonas aeruginosa e Candida albicans). Foram preparados extratos alcoólicos de própolis (EAP) e determinada a Concentração Inibitória Mínima (CIM) seguida do cálculo da CIM90%. A própolis de Botucatu foi a mais eficiente sobre S. aureus (0,3%v/v), Enterococcus sp (1,1%v/v) e C. albicans (2,1% v/v). Para E. coli, a própolis eficiente foi de Urubici (7,0%v/v) e...

Autores: Souza,Jaqueline Pérola de; Nogueira,Gustavo Milhomens; Mataqueiro,Maria Isabel; Queiroz-Neto,Antonio de.
O organofosforado diclorvós impregnado em coleiras plásticas é um recurso utilizado em medicina veterinária que visa ao controle de ectoparasitas de cães e gatos. O objetivo deste trabalho foi avaliar os efeitos do uso de coleiras plásticas impregnadas com diclorvós (8,37%) em ratas Wistar durante o período de gestação e lactação, como possível fonte de alterações comportamentais e da atividade colinesterásica cerebral dos filhotes. Na desmama, não houve diferença na atividade colinesterásica cerebral entre as mães tratadas com diclorvós e o grupo controle, bem como entre os respectivos filhotes. O tratamento com diclorvós também não influenciou no comportamento geral dos animais, avaliado no campo aberto, nem no nível de ansiedade testado no labirinto em...

Atividade e especiação química na solução afetadas pela adição de fósforo em latossolo sob plantio direto em diferentes condições de acidez
Provedor de dados: 90
Autores: Nolla,Antonio; Anghinoni,Ibanor.
No sistema plantio direto (SPD), ocorre acúmulo superficial de resíduos de culturas e de nutrientes, especialmente P e Ca, que contribuem para a inativação do Al3+ em solução. Assim, a presença desse elemento no solo não indica, necessariamente, que ocorre fitotoxidez, visto que ânions orgânicos e inorgânicos alteram a dinâmica do Al livre em solução, reduzindo sua atividade. Nestas condições, o conhecimento da atividade e da especiação iônica em solução pode ser útil para o entendimento da sua dinâmica no solo. No presente trabalho, determinaram-se a atividade e a especiação de íons na solução de um Latossolo, cultivado, há sete anos, no sistema plantio direto em diferentes condições de acidez provocadas pela adição anterior (1994) de doses de calcário....

Atmospheric forcing on the annual iron cycle in the western Mediterranean Sea: A 1-year survey
Provedor de dados: 5
Autores: Bonnet, Sophie; Guieu, Cecile.
A 1-year survey of simultaneous measurements of total atmospheric deposition and dissolved iron concentrations in surface waters (0-40 m) was performed in the northwestern Mediterranean Sea, an area with a marked seasonal hydrological regime. The total atmospheric iron flux was 1118 mg m(-2) (i.e., 20.4 mmol m(-2)). By using aluminium as a crustal marker the deposition was mainly attributed to Saharan dust deposition. Dissolved iron flux was estimated to be 42 mmol m(-2) yr(-1), of which 44% was anthropogenic in origin and 56% was of Saharan origin. Dissolved iron profiles revealed four typical situations throughout the year: (1) a winter situation with homogenous dissolved iron concentrations ranging from 0.8 to 0.9 nmol L(-1), (2) a spring situation with...

Atmospherically-promoted photosynthetic activity in a well-mixed ecosystem: Significance of wet deposition events of nitrogen compounds
Provedor de dados: 5
Autores: Boulart, C; Flament, Pierre; Gentilhomme, V; Deboudt, K; Migon, C; Lizon, F; Schapira, M; Lefebvre, Alain.
Wet atmospheric deposition of dissolved N, P and Si species is studied in well-mixed coastal ecosystem to evaluate its potential to stimulate photosynthetic activities in nutrient-depleted conditions. Our results show that, during spring, seawater is greatly depleted in major nutrients: Dissolved Inorganic Nitrogen (DIN), Dissolved Inorganic Phosphorus (DIP) and Silicic acid (Si), in parallel with an increase of phytoplanktonic biomass. In spring (March-May) and summer (June-September), wet atmospheric deposition is the predominant source (&gt; 60%, relative to riverine contribution) for nitrates and ammonium inputs to this N-limited coastal ecosystem. During winter (October-February), riverine inputs of DIN predominate (&gt; 80%) and are annually the most...

Provedor de dados: 91
Autores: Silva,Sérgio R.; Barros,Nairam F.; Costa,Liovando M.
Um experimento foi realizado para avaliar os efeitos da compactação sobre os atributos físicos de dois solos: um Latossolo Vermelho-Amarelo (LVA) oxídico-gibbsítico, e um Latossolo Amarelo (LA) caulinítico. O ensaio consistiu de oito pressões de compactação (0, 60, 120, 240, 360, 540, 720 e 900 kPa). Cada unidade experimental se compunha de anel de PVC com 6 cm de altura e 4,55 cm de diâmetro interno, na qual foram avaliadas: condutividade hidráulica, microporosidade, macroporosidade, porosidade total, resistência do solo à penetração e agregados estáveis em água. A retenção de água a 0,01 e 1,5 MPa, foi avaliada em amostras de solos compactados em anéis de PVC com 1,9 cm de altura e 4,55 cm de diâmetro interno. O solo caulinítico foi mais sensível à...

Atributos físicos de um argissolo e rendimento de culturas de acordo com o revolvimento do solo em plantio direto
Provedor de dados: 90
Autores: Marcolan,Alaerto Luiz; Anghinoni,Ibanor.
O sistema plantio direto melhora a qualidade estrutural do solo. Entretanto, o tráfego de máquinas pode levar à compactação superficial. Nessa situação, a mobilização para incorporar calcário, ao mesmo tempo que corrige a acidez na camada mobilizada do solo, reduz os possíveis efeitos negativos da compactação. Assim, avaliaram-se os efeitos de mobilizar ou não o solo por ocasião das reaplicações de calcário nos atributos físicos no perfil do solo e no rendimento de culturas em diferentes sistemas e tempos de manejo do solo. O experimento foi realizado na Estação Experimental Agronômica da UFRGS, em Eldorado do Sul (RS), em um Argissolo Vermelho distrófico típico. Os manejos foram: (a) sistema plantio direto 12 anos, (b) sistema plantio direto oito anos,...

Atributos físicos do solo e distribuição do sistema radicular de citros como indicadores de horizontes coesos em dois solos de tabuleiros costeiros do estado da Bahia
Provedor de dados: 90
Autores: Santana,Marlete Bastos; Souza,Luciano da Silva; Souza,Laercio Duarte; Fontes,Luiz Eduardo Ferreira.
Em 2001, foram realizadas a caracterização física e a avaliação do sistema radicular de citros em dois solos típicos de Tabuleiros Costeiros (Latossolo Amarelo-LA e Argissolo Acinzentado-PAC) do Estado da Bahia, visando estabelecer atributos que melhor identifiquem horizontes coesos. Em cada um dos solos, foram coletadas amostras nos primeiros quatro horizontes, para determinar granulometria, densidade do solo, porosidade total, macroporosidade, microporosidade e condutividade hidráulica saturada. Também foram determinadas a resistência do solo à penetração e a umidade crítica de resistência à penetração. Amostras de raízes de citros foram coletadas nos mesmos horizontes. Foi brusca a diminuição da densidade de raízes de citros nos horizontes AB, Bw1, BA e...

Attitudes and decision making amongst Scottish organic farmers
Provedor de dados: 21
Autores: Bayliss, Caroline; Clay, Tony.
The number of organic farmers in Scotland increased dramatically in the period between 1997 and 2000, from 120 in 1997 to approximately 600 at the end of 2000; a five fold increase. Currently the outlook for organic farming in Scotland appears positive, despite recent publicity about farmers leaving the sector. Market prospects for all organic commodities are buoyant and there are increased Scottish Executive Organic Aid Scheme (OAS) maintenance payments in the offing. But what do Scotland’s organic producers really think about the system, which has them, tied in for at least five years?  In June 2004, a representative group of Scottish organic farmers in the South of Scotland was surveyed to determine how many intended to continue farming organically once...

Autores: Staack,   Tosten; Schramm,   Matthias; Spiller,   Achim.
The Chinese consumer goods market is widely considered to be one of the economic hot spots of the world. China seems to be the market with the largest growth potential within the next decade. Multina - tional retail companies, for example, Wal-Mart, Metro and Carrefour have made large investments to open up this new market. However, parallel to the positive aspects of the market development, foreign retail companies entering the market encounter numerous risks and difficulties. Whereas questions concerned with logistical problems are being discussed more often, analyses focusing on the shopping behavior of Chinese consumers are rare. In this context, the following report provides information on store preferences based on a comprehensive survey of 800...

Auction Markets for Specialty Food Products with Geographical Indications
Provedor de dados: 31
Autores: Schamel,   Guenter.
We present a first analysis of auction markets for specialty food products. We identify auction prices, trade volume and value for domestic and foreign origin specialty ham with geographical indications (GIs) which were actually sold in online auctions in Germany within a one-month period. Applying hedonic modeling, we examine potential factors that may influence online bidding behavior and final auction prices. We estimate positive auction price effects for weight, bidding activity, and auction length, that the domestic product is sold at a discount, that higher shipping cost have a negative impact on final prices, and that auctions ending on Fridays and Saturdays yield lower prices. The model may be used to estimate the value of GIs. In our example, we...

Auctioning Conservation Payments using Environmental Indices
Provedor de dados: 31
Autores: Cattaneo,   Andrea.
A framework for analyzing conservation programs that rank applications using environmental indices is presented. We derive the optimal bid from the farmer's perspective for both land retirement and working lands agri-environmental payment programs and we analyze how these solutions depend on program design parameters. The distinction is made between environmental objectives based on whether the farmer exercises control or not over the level proposed in a bid to participate in a program. The optimization model is solved analytically for two cases - a land retirement and a working lands program - highlighting the differences in the results. For land retirement programs we conclude that, for the cases considered, the exogenous environmental performance does...

Audiological and electrophysiological evaluation of children with acquired immunodeficiency syndrome (AIDS)
Provedor de dados: 55
Autores: Matas,Carla Gentile; Leite,Renata Aparecida; Magliaro,Fernanda Cristina Leite; Gonçalves,Isabela Crivellaro.
We examined the peripheral auditory system and the auditory brainstem pathway of children with Acquired Immunodeficiency Syndrome (AIDS). One hundred and one children, 51 with AIDS diagnosis and 50 normal children were evaluated. Audiological assessment included immittance measures, pure tone and speech audiometry and auditory brainstem response (ABR). The children with AIDS more frequently had abnormal results than did their matched controls, presenting either peripheral or auditory brainstem impairment. We suggest that AIDS be considered a risk factor for peripheral and/or auditory brainstem disorders. Further research should be carried out to investigate the auditory effects of HIV infection along the auditory pathway.

Audit risk factors in certification: How can risk-oriented audits improve the quality of certification standards?
Provedor de dados: 31
Autores: Schulze,   Holger; Albersmeier,   Friederike; Spiller,   Achim; Jahn,   Gabriele.
Over the past few years, certification standards have become increasingly relevant for the agribusiness sector. Substantial parts of the value chain are already certified by standards such as QS, IFS or EurepGap. It is not known, however, whether these approaches can actually ensure a high quality control. This article is based on the analysis of the data base of the QSsystem with more than 72,000 companies involved. It tries to deduce some first empirically rich hypotheses about the connection between auditing quality and the institutional framing of the certification.

Autores: Clever, Michael.
Thinning trials with lime sulphur in comparison to other products were carried out for 4 years in an ‘Elstar orchard’ at the OVB Jork in Northern Germany. Beside the yield, the influence on fruit size, colour, russet-ting and return bloom of treated trees were observed. Mechanic thinning was too strong and had other negative effects. Thinning with potato meal and coconut soap had no effect. Organic oil (Telmion) reduced the yield between 0 and 20%. Lime sulphur reduced the yield 0 – 40% in comparison of the concentration and the number of applications. There were great fluctuations from year to year. In conclusion lime sulphur gives the best results, but the variation from year to year is not acceptable for a practical advising in the northern area of...

Autores: Mollers,   Judith.
Problem and objectives. Non-farm rural diversification is gaining prominence in the debate on rural development since the end of the 1990s. The expansion of non-farm employment and the diversification of incomes are important policy objectives because they offer a solution to the employment and structural problems of a shrinking agricultural sector. Development policies focusing on the rural non-farm sector aim at offering employment options and reducing urban migration. They can contribute to poverty reduction, economic growth and a more equal income distribution. This research is based on a household survey including 240 randomly selected rural households in the regions of Gorenjska and Pomurska in Slovenia as well as Gevgelija and Kumanovo in Macedonia....

Der ökologische Landbau in den neuen Mitgliedsländern der EU hat in den letzten Jahren eine sehr dynamische Entwicklung erfahren. Durch die verstärkte Förderung hat sich die Wirtschaftlichkeit des ökologischen Landbaus nach dem Beitritt zur EU deutlich erhöht. Westeuropäische Erzeuger fürchten die zunehmende Konkurrenz. Mittelfristig werden die östlichen Ökolandwirte ihre Kostenvorteile nur nutzen können, wenn sie Produktivitätsfortschritte erzielen. Auf der Absatzseite sind deutliche Investitionen in die Infrastruktur und in eine effektive Öko-verarbeitung und -Vermarktung erforderlich. Eine steigende inländische Nachfrage in Folge wirtschaftlicher Entwicklung kann den Exportdruck zusätzlich reduzieren, so dass mit einer „Schwemme“ mittel- und...

The present study describes an auxiliary tool in the diagnosis of left ventricular (LV) segmental wall motion (WM) abnormalities based on color-coded echocardiographic WM images. An artificial neural network (ANN) was developed and validated for grading LV segmental WM using data from color kinesis (CK) images, a technique developed to display the timing and magnitude of global and regional WM in real time. We evaluated 21 normal subjects and 20 patients with LVWM abnormalities revealed by two-dimensional echocardiography. CK images were obtained in two sets of viewing planes. A method was developed to analyze CK images, providing quantitation of fractional area change in each of the 16 LV segments. Two experienced observers analyzed LVWM from...

Automatic morphological detection of otolith nucleus
Provedor de dados: 5
Autores: Cao, Frédéric; Fablet, Ronan.
This paper deals with the automation of the acquisition of age and growth data from the analysis of otolith images. One of the key component of such it system is the automatic detection of the growth center, which serves as the basis for further processing (2D ring segmentation, age and growth estimation,...). To this end, we develop a new and well-founded approach combining a morphological analysis of image level sets to the a contrario, detection principle. This approach leads to a robust parameterless scheme, whose efficiency is demonstrated by an evaluation carried out for a set of several hundred of plaice otoliths. (c) 2005 Elsevier B.V.

Autumn applications of sulphur – a new approach to control the pear leaf blister  mite Eriophyes pyri
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite can cause severe damages to pear trees. By their hidden way of living inside  the leaf blisters, the mites are protected from plant protection agents. Until now, oil treatments  in early spring, when the mites leave their hibernation sites and invade the young leaves, are the  only possibility to control these mites. Because of the low temperatures during this period (February/  March) the efficacy of pesticides is often not reliable. The aim of this study was to assess the effects  of sulphur applied after harvest at the time, when mites are leaving the blisters and migrate to  the hibernation sites. The treatments were applied shortly after harvest to benefit from the mild temperatures  in September. Visual controls in...

Avaliação agronômica e econômica da aplicação de biossólido na produção de soja
Provedor de dados: 86
Autores: Lemainski,Jorge; Silva,José Eurípedes da.
O objetivo deste trabalho foi definir parâmetros técnicos e econômicos do uso de biossólido como fertilizante para a soja. A resposta da soja à aplicação de biossólido úmido, nas doses 0, 7,5, 15, 30 e 45 Mg ha-1 foi comparada à resposta ao fertilizante mineral, aplicado em quantidades equivalentes de NPK, por dois anos de cultivo, em um Latossolo Vermelho distrófico argiloso. Utilizou-se o delineamento experimental de blocos ao acaso, com nove tratamentos e três repetições. Biossólido e fertilizante mineral foram aplicados somente antes do primeiro cultivo. Na dose de 30 Mg ha-1 de biossólido úmido, as produções de 3.602 e 3.183 kg ha-1 de grãos, no primeiro e segundo cultivo, respectivamente, evidenciaram o efeito imediato e residual do material, o que...

Avaliação da eqüidade da Previdência no meio rural do Brasil
Provedor de dados: 123
Autores: Kreter,Ana Cecília; Bacha,Carlos José Caetano.
Este trabalho avalia a eqüidade do sistema brasileiro de aposentadorias pagas no meio rural, dando ênfase à década de 1990. Entende-se como eqüidade a distribuição de aposentadorias sem viés de cor (ou raça), sexo e nível de educação. Motivado pela Constituição Federal de 1988, as Leis nº 8.212 e nº 8.213, de 1991 permitiram que homens (com 60 anos de idade ou mais) e mulheres (com 55 anos de idade ou mais) que tivessem comprovado exercício da atividade rural pudessem obter aposentadoria de um salário mínimo, mesmo não tendo contribuído com o sistema previdenciário. Tais mudanças foram significativas, pois igualaram os direitos de mulheres e homens e fixaram um valor mínimo das aposentadorias. Usando a análise tabular de microdados da PNAD (para os anos de...

Avaliação da fixação biológica de nitrogênio na soja em áreas de primeiro cultivo no cerrado de Roraima.
Provedor de dados: 14
Autores: ZILLI, J. E.; MARSON, L. C.; CAMPO, R. J.; GIANLUPPI, V.; HUNGRIA, M.
Os trabalhos de pesquisa com soja têm desenvolvido novas tecnologias de cultivo e materiais genéticos que resultam em incremento sucessivo de produtividade e, por conseqüência, maior necessidade de nitrogênio (N). O N é o nutriente requerido em maior quantidade pela cultura, cerca de 80 kg a cada tonelada de grãos produzidos. As principais fontes de N disponíveis para a soja são os fertilizantes nitrogenados e a fixação biológica de nitrogênio (FBN) atmosférico. No Brasil, a FBN representa a fonte economicamente e ecologicamente mais viável para a cultura. A simbiose, que ocorre entre esta leguminosa e as bactérias do gênero Bradyrhizobium (bactérias do grupo rizóbio) resulta na formação de nódulos nas raízes da planta, possibilitando a obtenção de todo o...

Provedor de dados: 96
Autores: Abreu,Urbano Gomes Pinto de; Lopes,Paulo Sávio; Torres,Robledo de Almeida; Santos,Heleno do Nascimento.
O desempenho produtivo de 1.075 matrizes e a estrutura etária do rebanho foram monitorados durante cinco anos (maio de 1994 a maio de 1999) em uma fazenda com sistema extensivo de cria de bovinos de corte na região do Pantanal. Nesse período, tecnologias foram introduzidas com o objetivo de modificar o sistema tradicional de produção da região e, conseqüentemente, melhorar o desempenho produtivo do rebanho de cria como um todo. As vacas foram numeradas e monitoradas durante a realização dos trabalhos de gado (TG), sendo classificadas como solteira ou parida e, conforme avaliação do desempenho reprodutivo ao longo dos trabalhos de gado, eram mantidas no rebanho ou descartadas. Os resultados foram modelados por meio de equações de estimação generalizadas...

Autores: Freitas,Acyr Wanderley de Paula; Pereira,José Carlos; Rocha,Fernanda Cipriano; Costa,Marcone Geraldo; Leonel,Fernando de Paula; Ribeiro,Marinaldo Divino.
Objetivou-se avaliar as características fermentativas e a qualidade nutricional da silagem de cana-de-açúcar tratada com aditivos microbianos e enriquecida com 10% de resíduo da colheita de soja, com base no peso verde da cana. O experimento foi conduzido em delineamento inteiramente ao acaso, com três repetições, utilizando-se a variedade RB855536, colhida em soca aos 16 meses. Embora a adição do resíduo da colheita de soja tenha promovido aumento do pH final da silagem, os tratamentos com resíduo diminuíram em 33% as perdas de matéria seca das silagens e em 60% o teor de N-amoniacal em relação ao nitrogênio total. A adição dos inoculantes reduziu o pH da silagem quando em associação ao resíduo de soja, não exercendo efeito significativo sobre os outros...

Um subconjunto de animais foi também avaliado em quatro infestações artificiais. Os efeitos de grupo genético nas taxas de infecção por Babesia bigemina foram investigados no animal e no carrapato. Quando se consideraram as quatro infestações artificiais em conjunto, verificou-se que os animais dos grupos genéticos TA e TS apresentaram maior percentagem de recuperação, em comparação aos animais NI, enquanto os animais RC apresentaram taxa de recuperação intermediária, o que sugere maior resistência ao carrapato dos animais NI, resistência intermediária dos animais RC, e menor resistência dos bovinos dos grupos TA e TS. A estimativa de herdabilidade do número de carrapatos (0,15), apesar de baixa, indica que essa característica apresenta alguma variação...

Autores: Lima,   Lilian Maluf de; Oliveira,   Ana Maria Kefalas; Carletti,   Paulo de Tarso Filho; Ferrari,   Renata Cristina; Caixeta,   Jose Vicente Filho.
This study, conducted along the year 2003, was held in the environment of a cement company plant located in the São Paulo State. That industry has used carbon black as predominant energetic source which besides resulting a huge emission of gases (CO and CO2) into the atmosphere, has been more expensive than some other alternatives of biomass sources. Taking into consideration the location of that plant, there was a large supply of available biomass to be used as alternative fuel for industrial ovens. Several biomasses were analyzed and it was concluded that the sugar cane bagasse and residues of wood (sawdust and woodchips) were the most appropriate alternatives to such an industry.

Avaliação de características agronômicas e de produção de forragem e grãos de milho em diferentes densidades de semeadura e espaçamentos entre linhas
Provedor de dados: 64
Autores: Alvarez,Cláudio Garcia Durán; Von Pinho,Renzo Garcia; Borges,Iran Dias.
O milho Zea mays L. é muito utilizado para a produção de forragem e grãos em todo o mundo, devido ao seu grande potencial produtivo e adaptabilidade aos mais diferentes ambientes. Aspectos relacionados ao arranjo de plantas na área, como a densidade, o espaçamento e a arquitetura da cultivar, podem ser determinantes na produção de forragem e grãos. A redução do espaçamento e o aumento da densidade podem aumentar a produtividade e a eficiência operacional na cultura do milho. Visou-se com este trabalho, estudar o comportamento de híbridos de milho de diferentes arquiteturas foliares, submetidos a dois espaçamentos entre linhas e a duas densidades de plantas, em dois anos agrícolas. Em cada ano, foram conduzidos dois experimentos, sendo que no primeiro...

Avaliação de características bromatológicas da forragem de milho em diferentes densidades de semeadura e espaçamentos entre linhas
Provedor de dados: 64
Autores: Alvarez,Cláudio Garcia Durán; Von Pinho,Renzo Garcia; Borges,Iran Dias.
A grande utilização do milho Zea mays L. para a produção de forragem permitiu a maior intensificação da atividade pecuária. Além disso, por ter uma boa composição nutricional, possibilitou maiores ganhos na produção animal. O valor nutritivo do milho está diretamente relacionado ao arranjo de plantas, densidade de semeadura, espaçamento entre linhas e arquitetura da planta. Estes fatores podem interferir na composição nutricional da planta de milho. Em função disso, há uma tendência de redução no espaçamento e aumento na densidade de semeadura, privilegiando assim cultivares de arquitetura mais ereta. Buscou-se com este trabalho avaliar o comportamento de híbridos de milho de diferentes arquiteturas foliares, submetidos a dois espaçamentos entre linhas e...

Como alternativa de genótipos de bananeira para o semi-árido irrigado do norte de Minas Gerais, foram avaliados quatro ciclos de produção da variedade Caipira (AAA) e dos híbridos SH3640 (AAAB), FHIA 1 (AAAB), FHIA 18 (AAAB) e Pioneira (AAAB), além de três ciclos da variedade Prata-Anã (AAB), no espaçamento 3 m x 2,7 m, em delineamento inteiramente casualizado, com 25 repetições de uma planta. Foram avaliados caracteres da planta e da produção, levando à conclusão de que os genótipos 'SH3640', 'FHIA 1' e 'FHIA 18' são mais produtivos que a 'Pioneira', 'Caipira' e 'Prata-Anã'. A 'Pioneira' apresentou maior crescimento inicial, porém, na floração, a maior altura foi apresentada pela 'Caipira', sendo que todos os genótipos se igualaram no quarto ciclo. A...

Avaliação de métodos para estimativa de coeficientes da cultura de amendoim
Provedor de dados: 91
Autores: Silva,Luiz C.; Rao,Tantravahi V. R.
A cultura do amendoim é uma alternativa agrícola importante para os perímetros irrigados do Nordeste brasileiro, em especial aqueles localizados em áreas de solos de textura arenosa, por sua baixa exigência hídrica, ciclo curto e uma demanda não atendida no mercado regional. Realizou-se este trabalho buscando-se avaliar diferentes métodos que determinam as necessidades hídricas da cultura do amendoim. O consumo hídrico da cultura foi determinado através de medições em evapotranspirômetros de lençol freático constante. A evapotranspiração de referencia foi obtida através de diferentes métodos. Constatou-se que a demanda hídrica da cultura é da ordem de 650 mm e o coeficiente de cultura (kc) obtido pelos métodos do Tanque Classe A, Hargreaves e Thornthwaite,...

Avaliação de riscos ambientais de agrotóxicos em condições brasileiras.
Provedor de dados: 14
Autores: SPADOTTO, C. A.
O consumo anual de agrotóxicos no Brasil tem sido superior a 300 mil toneladas de produtos comerciais. Expresso em quantidade de ingrediente-ativo (i.a.), são consumidas anualmente no país cerca de 130 mil toneladas; representando um aumento no consumo de agrotóxicos de 700% nos últimos quarenta anos, enquanto a área agrícola aumentou 78% nesse período (SPADOTTO et al., 2004). Além dos perigos aos seres humanos, nos aspectos ocupacionais, alimentares e de saúde pública, sabe-se que a introdução de agrotóxicos no ambiente pode provocar efeitos indesejáveis, tendo como conseqüência mudanças no funcionamento do ecossistema afetado. De acordo com o Decreto 4.074/2002, é competência do Comitê Técnico de Assessoramento para Agrotóxicos (nele instituído) elaborar...

Avaliação de sementes de acerola por meio de raios-x
Provedor de dados: 94
Autores: Nassif,Daniel Silveira Pinto; Cícero,Silvio Moure.
O teste de raios-X tem sido utilizado por ser um método rápido, preciso e não-destrutivo. Neste contexto, o presente trabalho foi realizado com o objetivo de verificar a possibilidade de sua utilização na detecção de anormalidades em embriões de sementes de acerola. Sementes, dos clones Olivier e Waldy e de "pé-franco", foram radiografadas (radiação de 16 kv e tempo de exposição de 180 segundos) e classificadas em função das condições em que seus embriões se encontravam (morfologicamente normais, morfologicamente anormais ou ausentes). Após a radiografia, as sementes foram colocadas para germinar e, em seguida, as plântulas e as sementes mortas foram fotografadas e disponibilizadas em computador juntamente com as respectivas imagens de raios-X. A técnica...

Autores: Souza,Luís O. C. de; Mantovani,Everardo C.; Soares,Antonio A.; Ramos,Márcio M.; Freitas,Paulo S. L. de.
Este trabalho foi conduzido no período de agosto a outubro de 1999, com o objetivo de avaliar os sistemas de irrigação por gotejamento utilizados na cafeicultura irrigada do norte do Espírito Santo e nas áreas de cerrado de Minas Gerais e caracterizar a porcentagem de área molhada (PAM) nesses sistemas de irrigação. Foram realizadas medidas das dimensões do bulbo molhado para determinação da porcentagem de área molhada. Pelos resultados obtidos verificou-se que, dos valores de coeficiente de uniformidade de distribuição determinados, apenas um sistema apresentou valor abaixo de 70%, refletindo uma uniformidade ruim. No que se refere aos demais resultados, dez sistemas indicaram valores de uniformidade de distribuição entre 70 e 80%, oito sistemas mostraram...

Avaliação do desempenho do modelo CLIGEN em gerar dados climáticos para modelos hidrológicos e agronômicos
Provedor de dados: 91
Autores: Evangelista,Adão W. P.; Ferreira,Paulo A.; Pruski,Fernando F.; Sediyama,Gilberto C.
Tendo em vista o grande número de variáveis que envolvem e dificultam a avaliação de sistemas agronômicos e hidrológicos, a utilização de modelos torna-se desejável, pois proporciona rapidez para a análise dos resultados, além de permitir que um grande número de fatores e efeitos seja contabilizado. A utilização desses modelos requer, na maioria das vezes, uma base de dados climáticos onde alguns dos elementos não são registrados em muitas estações climáticas localizadas no território brasileiro e, normalmente, as séries históricas existentes são de curta duração sendo, portanto, pouco representativas. Desta forma, objetivou-se, com este trabalho, avaliar o desempenho do modelo CLIGEN, quanto a gerar os elementos climáticos normalmente utilizados como...

Avaliação do impacto da utilização de crédito, da educação e da escolha do canal de comercialização na horticultura: caso do núcleo rural do Distrito Federal
Provedor de dados: 123
Autores: Pereira,Sebastião Eustáquio; Figueiredo,Adelaide dos Santos; Loureiro,Paulo R. A.
O objetivo deste artigo consiste identificar a influência de diversos fatores relacionados com a renda do agricultor familiar, que podem reforçar ou não a idéia básica contida na política de fortalecimento da agricultura familiar implementada pelo Governo desde 1996. Os retornos foram estimados baseados em regressão linear (OLS) em dois estágios, com a equação do segundo momento sendo corrigida pela incorporação da razão inversa de Mills gerada com o resultado do modelo probit, onde é estimada a possibilidade do horticultor demandar ou não crédito. Ficou evidenciada a desvantagem da negociação através dos grandes supermercados, que tendem a comprimir, conforme constatado por Melo (2001), a remuneração dos fornecedores de hortaliças.

Autores: Brunetto,Gustavo; Melo,George Wellington; Kaminski,João; Furlanetto,Vaneila; Fialho,Flávio Bello.
A matéria orgânica do solo nos laboratórios de rotina de análise de solo, em geral, é determinada por métodos de combustão úmida. Entretanto, esses métodos contaminam com cromo os efluentes laboratoriais. Assim, surge a necessidade de avaliar métodos alternativos de determinação da matéria orgânica do solo. O presente trabalho teve como objetivo avaliar o desempenho do método de perda de peso por ignição como método alternativo e que não possui o contaminante cromo na análise de matéria orgânica do solo, tendo sido realizado no Laboratório de Análise de Solo e Tecido Vegetal da Embrapa Uva e Vinho, no município de Bento Gonçalves, RS.

Autores: Silva,Késia O. da; Nääs,Irenilza de A.
O mercado consumidor, atualmente, exige aumento gradativo do controle da qualidade dos produtos. Os métodos manuais de controle existentes, aplicáveis à produção animal, começam a se mostrar ineficientes para garantir percentual crescente dessa qualidade, pois essa garantia somente pode ser efetiva se houver rastreamento confiável do animal, desde o seu nascimento até o abate. A identificação individual apresenta grande importância nesse enfoque, pois possibilita a coleta de informações inerentes ao animal. A rastreabilidade eletrônica utiliza dispositivo eletrônico, que emite um sinal ativado por um leitor fixo, colocado onde for necessário registrar um determinado evento, ou um leitor manual que permite maior independência do operador.

Avaliação e aplicação de testes para a detecção da autocorrelação espacial usando marcadores genéticos
Provedor de dados: 64
Autores: Louzada,João Marcos; Bearzoti,Eduardo; Carvalho,Dulcinéia de.
O índice I de Moran é a ferramenta usual para se medir a intensidade da autocorrelação espacial em dados de marcadores genéticos. A estatística I é assintoticamente normalmente distribuída, podendo ser avaliada como desvios da normal padrão mediante o suposto-N (aproximação normal). Porém, para pequenos números de populações (m&lt;8), deve-se aplicar o teste de aleatorização de Mantel (suposto-R), desenvolvido por Mantel (1967). Assim, por meio do presente estudo, buscou-se avaliar o desempenho de ambos os testes no que tange às taxas de erro tipo I e o poder dos mesmos. Estes foram avaliados via simulação de Monte Carlo, em que analisaram-se, sob a H0, as situações {p=0,1, p=0,25 e p=0,5} de freqüências alélicas médias, para as quais consideraram-se os...

Avaliação econômica da poluição do ar na Amazônia Ocidental: um estudo de caso do Estado do Acre
Provedor de dados: 123
Autores: Silva,Rubicleis Gomes da; Lima,João Eustáquio de.
Os problemas ocasionados pela poluição do ar em razão das queimadas existentes dentro e fora do Estado do Acre têm causado sérios prejuízos à saúde da população. Como as queimadas provocam malefícios à sociedade, a mensuração da disposta a pagar (DAP) para diminuir esses impactos, constitui importante informação para avaliar se um projeto de despoluição é viável economicamente. De forma geral, objetivou-se analisar os impactos da poluição do ar pelas queimadas sobre a sociedade acreana. Especificamente: a) determinar quanto a sociedade está disposta a pagar pela diminuição dos malefícios ocasionados pelas queimadas; e b) comparar o valor da disposição a pagar agregada com o custo das morbidades respiratórias no ano de 2004. A teoria das externalidades é...

Provedor de dados: 45
Autores: Moura,C.S.; Guerra,M.M.P.; Silva Júnior,V.A.; Silva,C.G.C.; Caju,F.M.; Alves,L.C.
Avaliou-se o efeito da ivermectina sobre o parênquima testicular através da produção espermática diária e da eficiência da espermatogênese em ratos Wistar adultos tratados com diferentes dosagens (200, 400 e 600µg/kg). Pela avaliação histomorfométrica, o parênquima testicular e o processo espermatogênico dos ratos Wistar não sofreram qualquer efeito deletério da aplicação de ivermectina, o que foi confirmado pela manutenção da produção espermática diária por testículo, pelo rendimento intrínseco da espermatogênese (PED/g/t) e pela manutenção da estrutura do parênquima testicular. Com base nos resultados quantitativos e qualitativos da espermatogênese, é possível concluir que a ivermectina não tem efeito tóxico-degenerativo sobre o parênquima testicular de...

Avaliações químicas e bioquímicas dos grãos, extratos e tofus de soja comum e de soja livre de Lipoxigenase
Provedor de dados: 64
Autores: Ciabotti,Sueli; Barcellos,Maria de Fátima Píccolo; Mandarino,José Marcos Gontijo; Tarone,Adriana Gadioli.
Com este trabalho, objetivou-se avaliar a composição química e aspectos bioquímicos de soja comum, comum branqueada e livre de lipoxigenases e o efeito do processamento dos seus respectivos extratos de soja e tofus. A composição centesimal das cultivares de soja comum e livre de lipoxigenase não se diferenciaram (p&gt;0,05). Alterações na composição centesimal e de minerais dos extratos de soja e dos tofus foram atribuídas ao tratamento térmico (98 ºC/5 minutos) a que foi submetido o grão de soja comum e à etapa de maceração dos grãos, ficando evidente que algumas substâncias hidrossolúveis, foram migradas para a água de maceração dos grãos; o branqueamento na soja comum no início do processamento reduziu o teor de alguns minerais do extrato de soja (leite...

Aves ameaçadas ocorrentes no Pantanal.
Provedor de dados: 14
Autores: NUNES, A. P.; TICIANELI, F. A. T. TOMÁS, W. M.
O Pantanal é um ecossistema extraordinário e importante para muitas espécies de aves, principalmente as aquáticas, que ocorrem em abundância, e as migrantes em larga escala que utilizam a planície de inundação como sítio de forrageio e descanso, durante seus deslocamentos entre o Sul do continente Americano e o Hemisfério Norte (Sick, 1997; Nunes e Tomas, 2004b; Nunes e Tomas, no prelo). Brown Jr. (1986) relaciona cerca de 657 espécies de aves para a planície e áreas limítrofes e Mittermeier et al. (2003) 463 espécies. No entanto Tubelis e Tomas (2003), listam 465 espécies de aves na planície, e citam outras 50 que podem ocorrer. Publicações mais recentes revelam a ocorrência de 17 novas espécies para a planície do Pantanal (Antas e Palo Jr., 2004;...

Avoiding biases from data-dependent specification search: an application to a tillage choice model
Provedor de dados: 31
Autores: Sengupta,   Sanchita; Kurkalova,   Lyubov A.; Kling,   Catherine L.
The study evaluates the gains of avoiding data-dependent specification search on an estimation sample in an application to discrete choice models. We incorporate data splitting, the process by which the total available sample is randomly split in two or more sub-samples with the first (specification) sub-sample used for specification search, and the second (estimation) sub-sample used for obtaining clean estimates using the model chosen on the specification sub-sample according to a set criterion. We estimate 14 binary Logit models of the adoption of conservation tillage corresponding to the major sub-watersheds of the Upper Mississippi River Basin. For each of the sub-watershed models, we use the specification sub-sample to choose the explanatory...

Babesia gibsoni: An apical membrane antigen-1 homologue and its antibody response in the infected dogs
Provedor de dados: 19
Autores: Zhou, Jinlin; Yang, Jun; Zhang, Guohong; Nishikawa, Yoshifumi; Fujisaki, Kozo; Xuan, Xuenan.
A cDNA encoding the apical membrane antigen-1 (AMA-1) homologue was obtained by immunoscreening a cDNA expression library prepared from Babesia gibsoni merozoite mRNA. The complete nucleotide sequence of the gene was 2062 bp. Computer analysis suggested that the sequence contains an open reading frame of 1794 bp with a coding capacity of approximately 66 kDa. Based on the homology analysis, this putative protein was designated as B. gibsoni AMA-1 (BgAMA-1). The BgAMA-1 gene was expressed in the Escherichia coli BL21 strain and used as the antigen in Western blotting and the enzyme-linked immunosorbent assay (ELISA). The results indicated that BgAMA-1 was recognized as an immunodominant antigen by the host immune system and that it induced a strong antibody...

Studies on the impact of Eucalyptus spp. on Brazilian soils have focused on soil chemical properties and isolating interesting microbial organisms. Few studies have focused on microbial diversity and ecology in Brazil due to limited coverage of traditional cultivation and isolation methods. Molecular microbial ecology methods based on PCR amplified 16S rDNA have enriched the knowledge of soils microbial biodiversity. The objective of this work was to compare and estimate the bacterial diversity of sympatric communities within soils from two areas, a native forest (NFA) and an eucalyptus arboretum (EAA). PCR primers, whose target soil metagenomic 16S rDNA were used to amplify soil DNA, were cloned using pGEM-T and sequenced to determine bacterial diversity....

Provedor de dados: 58
Autores: Schöbitz,Renate P.; Bórquez,Pamela A.; Costa,Marcia E.; Ciampi,Luigi R.; Brito,Carmen S.
Three culture media were studied for the bacteriocin like substance (BLS) production from Carnobacterium piscicola L 103 in a batch and continuous culture system. The efficacy of the antagonistic substance against Listeria monocytogenes was tested on vacuum packaged salmon. BLS was produced in a 1.0 L bioreactor by batch and continuous culture using D-MRS, mod. D-MRS and APT as nutrient broths. Salmon fillets were inoculated with BLS (200 AU mL-1 and 800 AU mL-1) and 8.0 x 10¹ cfu cm-2 of L. monocytogenes and stored at 4ºC. The growth of L. monocytogenes was determined every 5 days during 15 days. After 12 h of batch culture the stationary growth phase of C. piscicola L 103 started, with a BLS activity of 800 AU mL-1 in D-MRS and mod. D-MRS broth, and of...

Provedor de dados: 21
Autores: Köppler, Kirsten; Storch, Volker; Vogt, Heidrun.
In 2005 initial experiments were carried out to control Rhagoletis cerasi with bait sprays. We used GF-120  fruit fly bait which contains Spinosad and NeemAzal®-T/S mixed in a sugar-yeast hydrolysate solution. 30 ml  of bait sprays were applied on single cherry trees in field cages, where we released a defined number of  cherry fruit flies. One experiment with GF-120 resulted in a reduction of fruit infestation of 96 % compared  with the control. In other trials with GF-120 and Neem bait the effect on the cherry fruit fly population was  monitored. After 24 hours GF-120 in a 5 % and 20 % solution led to a high reduction of flies (efficacy 85 %),  whereas NeemAzal®-T/S in a 5 %, 10 %, and 20 % solution only resulted in efficacies between 34 % and  42 %.

Autores: Herrero,M. A.; Gil,S. B.; Flores,M. C.; Sardi,G. M.; Orlando,A. A.
Los balances de nutrientes permiten conocer el potencial de riesgo ambiental de los sistemas productivos. Se evaluaron los balances de nitrógeno (N) y fósforo (P) y sus eficiencias de aprovechamiento a través de tres indicadores, a escala predial, en sistemas de producción primaria de leche bovina en Cuenca de Abasto de Buenos Aires. El cálculo de balances se realizó por diferencia entre ingresos y egresos para cada mineral en 17 establecimientos, en base anual, expresados en ton/año y en producto (N-P(gramos)/ leche producida (Litros)). La magnitud de ambos balances, en ton/año, mostró asociación al tamaño de explotación (p&lt;0,05), no así expresado por producto. Los principales ingresos para N fueron alimentos externos y fijación de nitrógeno, y para P,...

This article addresses the question, to what extent and under which conditions nontimber forest product (NTFP) trade leads to both livelihood improvement and forest conservation. We based the analysis on a standardized expert-judgment assessment of the livelihood and environmental outcomes of 55 cases of NTFP trade from Asia, Africa, and Latin America. The results show that NTFP trade benefits several components of peoples' livelihoods, but may increase inequality between households. Involvement of women in the production-to-consumption system (PCS) tends to have a positive impact on intrahousehold equity. In 80% of the cases, the commercial production of NTFPs does not enable people to make financial investments to increase quality and quantity of...

Balancing soil organic matter in organic agriculture - a theoretical approach
Provedor de dados: 21
Autores: Brock, Dipl.geogr. Christopher; Leithold, Prof.Dr. Günter.
Soil organic matter (SOM) balances can assist sustainable organic matter management. Still, existing methods need to be revised, especially when applied in organic farming. A basic problem is the linear concept which seemingly does not reflect the effective dynamic.  Furthermore the relevance of SOM is dependent on the cultivation system and cultivation intensity, respectively. The importance of SOM as a nutrient source increases with diminishment of cultivation intensity, i.e. synthetic fertilizer application. Here turnover of organic matter becomes the key factor for nutrient supply.  Correspondingly, a higher SOM reproduction level that promotes increased SOM content and/or turnover should be an objective in organic farming.  Soil organic matter...

Balancing the Multiple Objectives of Conservation Programs
Provedor de dados: 31
Autores: Cattaneo,   Andrea; Hellerstein,   Daniel; Nickerson,   Cynthia J.; Myers,   Christina.
Many of the Nation’s conservation programs seek to achieve multiple environmental objectives. Implementing a multi-objective program efficiently requires program managers to balance different environmental and cost objectives. A number of conservation programs use an index approach to prioritize objectives and rank program applications. This approach keeps program objectives distinct and enables program managers to use weights to determine the relative importance of each objective. This report provides empirical evidence on the environmental and cost tradeoffs of different index weighting schemes in USDA’s Conservation Reserve Program (CRP). The analyses take into account both land characteristics and how changes to an index affect producer decisions to...

Autores: Del Claro,Gustavo Ribeiro; Zanetti,Marcus Antonio; Correa,Lisia Bertonha; Netto,Arlindo Saran; Paiva,Fernanda Alves de; Salles,Marcia SaladineVieira.
O objetivo deste trabalho foi estudar o efeito do balanço cátion-aniônico da dieta (BCAD) no balanço e concentração sérica de cálcio em ovinos da raça Santa Inês. O delineamento experimental foi em blocos para controlar o efeito do peso inicial dos animais. Foram utilizados cinco tratamentos com níveis crescentes de BCAD (-160, -40, 140, 250 e 500mEq/kg de matéria seca) com cinco repetições em 25 animais. O BCAD influencia o metabolismo de cálcio em ovinos machos da raça Santa Inês. Com a diminuição do BCAD o cálcio sérico aumentou. Dietas aniônicas aumentaram a excreção urinária de cálcio, entretanto a retenção não foi afetada.

Autores: Rodrigues,Alexandre Couto; Herter,Flávio Gilberto; Veríssimo,Valtair; Campos,Ângela Diniz; Leite,Gabriel Berenhauser; Silva,João Baptista da.
As pereiras européias e asiáticas, cultivadas sob condições de inverno ameno, como na região Sul do Brasil, apresentam problemas de adaptação. Durante o inverno, as oscilações térmicas e o baixo acúmulo de frio têm sido referidos por alguns autores como causas do abortamento de gemas florais. O objetivo deste trabalho foi determinar o balanço de carboidratos em tecidos de gemas florais de duas cultivares de pereiras: Kieffer (P. communis x P. pyrifolia) e Housui (P. pyrifolia). Os tecidos de gemas florais e da base de gemas foram coletados mensalmente, de fevereiro a setembro de 2002, de plantas de pomar da Embrapa Clima Temperado, Pelotas-RS, coordenadas 32°51' S e 52°21'O, localizado a 230 metros de altitude.

Provedor de dados: 31
Autores: Baker,   Gregory A.; Zhang,   Fan.
Sonoma Foie Gras is one of three producers of foie gras in the U.S. and the sole producer in California. The company employs the practice of force-feeding ducks and geese to produce this culinary delicacy. The case describes the foie gras industry and pending legislation in California, which would ban the practice of force-feeding ducks and geese as well as the sale of the products of force-feeding birds. Readers are asked to conduct a stakeholder analysis to identify the primary stakeholders and their interests, and to identify alternatives and a course of action for Sonoma Foie Gras.

Bargaining and market power in a GIS-based hedonic pricing model of the agricultural land market
Provedor de dados: 31
Autores: Cotteleer,   Geerte; Gardebroek,   Cornelis.
Agricultural land markets differ greatly from the textbook-case of perfect competition. This is why standard hedonic pricing techniques should be revised before applying this technique to this market. The objective of this paper is to determine (a) the deviation from the competitive market price of agricultural land in the Netherlands due to market power and the existence of an excess surplus and (b) the effect of bargaining power on the division of excess surplus between the eventual seller and the buyer in the market for agricultural land.

Bargaining on Ecological Main Structures for Natural Pest Control: Modelling Land Use Regulations as Common Property Management
Provedor de dados: 31
Autores: Nuppenau,   Ernst-August.
In this paper we argue that the loss of bio-diversity hould be of concern for farmers, though it seems to be of little or no concern to them at the moment. As diversity is a component of nature that controls the growth of pests, a loss of bio-diversity means increased exposure to pests, danger of crop failures and, in the long run, lower average yields and profits. So far farmers buy costly pesticides for compensating the reduction of bio-diversity. We argue that institutional problems are the reason why farmers are not concerned with bio-diversity, and show that under pure private property rights farmers have interest in pesticides and not in bio-diversity as a measure of crop protect because they have perhaps to devote land to the natural eco-system. In...

Bark consumption of creosote bush (Larrea cuneifolia) by cuises (Microcavia australis): effect on branch survival and reproduction
Provedor de dados: 67
Autores: Campos,Claudia M; Borghi,Carlos E; Giannoni,Stella M; Mangeaud,Arnaldo; Tognelli,Marcelo F.
Locally, mammalian herbivores may have significant effects on the abundance and fitness of plant species. This study focuses on the interaction between cuises (Microcavia australis-Rodentia-) and creosote bush (Larrea cuneifolia -Zygophyllacea-), which is a widespread and ecologically dominant evergreen shrub in the Monte Desert of Argentina. Specifically, we examined the probability of plants being gnawed by cuises in relation to branch diameter and distance to cuis colonies. Additionally, we assessed the effect of gnawing by cuises on branch condition, production of flowers and fruits and branch survival. In general, gnawing by cuises negatively affects creosote bush plants. The likelihood of being gnawed is higher for branches of smaller diameter and in...

Barriers Facing New Entrants to Farming – an Emphasis on Policy
Provedor de dados: 31
Autores: Williams,   Fiona.
Recent UK studies highlight some of the challenges of adjustment facing the farming industry; an ageing farming population, a common absence of successor, and economic barriers combining to deter new entrants to the industry. Yet the future of farming is dependent on continued entry by new farm operators, either through the family farm business, new entrants from other sectors or via the ‘agricultural ladder’ i.e. from a farm worker to tenant to owner operator. Evidence suggests that new entrants in each situation encounter difficulties, some generic and some specific to individual cases. What is unclear is the role and influence of a range of policies on new entrant decisions. At a time when the farming industry is under pressure to compete and adjustment...

Barriers to the adoption of organic agriculture An investigation using the Theory of Planned Behaviour
Provedor de dados: 21
Autores: Hattam, Caroline.
Certified organic production by small-scale farmers in developing countries is increasingly promoted as an opportunity to access a growing and dynamic market while at the same time, enhance productivity and improve incomes. Nevertheless, adoption has been slow. The economics literature suggests profitability is the main constraint; however, the sustainable agriculture literature is inconclusive and considers attitudes of significant importance. As ecological behaviour is susceptible to a wide range of influences beyond an individual’s control, environmental attitude alone is often a poor predictor of behaviour (Kaiser et al., 1999). The Theory of Planned Behaviour (Ajzen, 1985) is therefore promoted for studies in the ecological domain as in addition to...

Bartonellosis: suggestive case reports in adult and pediatric patients and therapeutic issues
Provedor de dados: 55
Autores: Manfredi,Roberto; Sabbatani,Sergio.
Cat-scratch disease warrants extensive investigation, from an epidemiological, a diagnostic, but especially a therapeutic point of view. Two suggestive episodes of Bartonella henselae-caused cat-scratch disease are reported, and discussed in the light of the most recent literature evidence. The first case occurred in a 60-year-old man, thus suggesting that it is important to maintain an elevated level of suspicion for this disease in adults as well. Both episodes were characterized by a very prolonged and complicated disease course (with the involvement of three lymph node sets in the first case), a need for lymph-node drainage, and apparently negligible activity of many antimicrobial courses, with a very slow local cure. While specific culture and...

Population dynamics of European eels Anguilla anguilla was investigated within a small dammed catchment of Britanny (the Fremur) over a 8-years period (from 1996 to 2003). On this period, the migrant (recruitment and escapement) and sedentary (stock) fractions were quantified and characterized (stage, length and age). The mortality rate observed was important (53.2%) probably because of the high abundance (0.40 eels.m-2) and the habitatloss. Each year, the number of potentially emigrant eels, based on an analysis of the sedentary population fraction, was predicted. The observed number was strongly dependent on environmental conditions that were overruled by dam management. Finally, influence of growth site on production of both number and quality of...

Basin-wide estimates of the input of methane from seeps and clathrates to the Black Sea
Provedor de dados: 5
Autores: Kessler, Jd; Reeburgh, Ws; Southon, J; Seifert, R; Michaelis, W; Tyler, Sc.
Numerous methane-emitting bottom features, such as seeps, methane clathrate hydrates (clathrates), and mud volcanoes, have been identified recently in the Black Sea. The fluxes of methane from these sources averaged over large spatial scales are unknown. Here we take advantage of the fact that the Black Sea is a semi-enclosed basin with restricted deep water circulation to establish first-order estimates of basin-wide fluxes of methane from these sources to the water column and atmosphere. First, we measured tile natural radiocarbon content of methane (C-14-CH4) dissolved in the water column and emitted from seeps. The C-14-CH4 results showed that the dominant source of methane to the water column is emitted from seeps and a smaller source is...

Batch ethanol fermentation: the correlation between the fermentation efficiency and the biomass initial concentration depends on what is considered as produced ethanol
Provedor de dados: 58
Autores: Borzani,Walter.
Although numerous studies have examined many of the factors that affect the efficiency of batch ethanol fermentation, little attention has been paid to the influence of the biomass concentration on this efficiency. This paper shows that the influence of the biomass initial concentration on the fermentation efficiency depends on what is considered "produced ethanol". If only the ethanol present in the medium aqueous phase at fermentation completion is considered, the fermentation efficiency linearly decreases when the biomass initial concentration increases. If, however, the intracellular ethanol is also considered as produced ethanol, the fermentation efficiency is not affected by the biomass concentration.

Bathymetry is foundational data, providing basic infrastructure for scientific, economic, educational, managerial, and political work. Applications as diverse as tsunami hazard assessment, communications cable and pipeline route planning, resource exploration, habitat management, and territorial claims under the Law of the Sea all require reliable bathymetric maps to be available on demand. Fundamental Earth science questions, such as what controls seafloor shape and how seafloor shape influences global climate, also cannot be answered without bathymetric maps having globally uniform detail. Current bathymetric charts are inadequate for many of these applications because only a small fraction of the seafloor has been surveyed. Modern multibeam echosounders...

Bayesian analysis in Stata with WinBUGS
Provedor de dados: 31
Autores: Thompson,   John M.; Palmer,   Tom M.; Moreno,   Santiago G.
WinBUGS is a program for Bayesian model fitting by Gibbs sampling. WinBUGS has limited facilities for data handling, whereas Stata has no routines for Bayesian analysis; therefore, much can be gained by running Stata and WinBUGS together. We present a set of ado-files that enable data to be processed in Stata and then passed to WinBUGS for model fitting; finally, the results are read back into Stata for further processing.

Bayesian analysis of the linear reaction norm model with unknown covariate
Provedor de dados: 21
Autores: Su, G.; Madsen, P.; Lund, M.S.; Sørensen, D.; Korsgaard, I.R.; Jensen, J.
The reaction norm model is becoming a popular approach for the analysis of G x E interactions. In a classical reaction norm model, the expression of a genotype in different environments is described as a linear function (a reaction norm) of an environmental gradient or value. A common environmental value is defined as the mean performance of all genotypes in the environment, which is typically unknown. One approximation is to estimate the mean phenotypic performance in each environment, and then treat these estimates as known covariates in the model. However, a more satisfactory alternative is to infer environmental values simultaneously with the other parameters of the model. This study describes a method and its Bayesian MCMC implementation that makes...

B-chromosomes in two Brazilian populations of Dendropsophus nanus (Anura, Hylidae)
Provedor de dados: 74
Autores: Medeiros,Lilian R.; Rossa-Feres,Denise C.; Jim,Jorge; Recco-Pimentel,Shirlei M.
We report on the presence of B-chromosomes in two populations of Dendropsophus nanus (= Hyla nana Boulenger, 1889) from São Paulo State, Brazil. Such chromosomes were observed in 4 out of 43 specimens (9.3%) and in 9 out of 15 specimens (60%) from the municipalities of Nova Aliança and Botucatu, respectively. The karyotype 2n = 30 + 1B found in D. nanus was similar to that of other species with 2n = 30 chromosomes, except for the presence of an additional small telocentric chromosome. In one specimen from Botucatu, cells with one to three extra chromosomes were observed. These B-chromosomes appeared as univalent in meiosis I and did not bear a nucleolar organizer region or exhibit constitutive heterochromatin.

Beak-trimming methods and their effect on the performance of japanese quail pullets (Coturnix japonica)
Provedor de dados: 89
Autores: Pizzolante,CC; Garcia,EA; Saldanha,EAPB; Laganá,C; Batista,L; Deodato,Ap; Souza,ALP.
This study aimed at verifying if beak-trimming methods in Japanese quail pullets could optimize production by decreasing stress caused by cannibalism. A total number of 816 day-old Japanese quails was distributed in a completely randomized experimental design in a 2 x 3 factorial arrangement, with two beak-trimming ages (14 and 21 days of age) and three beak-trimming sizes (not trimmed, 1/3 trimmed, or 1/2 trimmed), and 4 replicates of 34 birds per replicate. Birds were submitted to the same management and feeding conditions. Weight gain, feed intake, feed conversion ratio, and mortality were evaluated. There was no significant effect of age at beak trimming on the evaluated parameters (P&gt;0.05), as well as no significant interaction between age at beak...

Beef Cattle Production and Management Practices and Implications for Educators
Provedor de dados: 31
Autores: Vestal,   Mallory K.; Ward,   Clement E.; Doye,   Damona G.; Lalman,   David L.
Beef producers need to continually incorporate new information and adopt new technology to effectively manage production costs.  Oklahoma State University began a Master Cattleman program with this need in mind.  Understanding technology adoption by producers requires identifying current management practices.  Data from a survey developed as part of the Master Cattleman program document current practices.  Management practices were examined for two groups; producers with smaller herds who are less dependent on the beef enterprise for family income, and producers with larger herds who are more dependent on beef.  Results clearly show that size and dependence on the beef enterprise matters when considering a broad spectrum of beef management practices.

Marmosets (Callithrix spp.) have been introduced widely in areas within Rio de Janeiro state assigned for the reintroduction of the endangered golden lion tamarin (Leontopithecus rosalia). The objetives of this study were to estimate the marmoset (CM) population in two fragments with reintroduced golden lion tamarin to quantify the association and characterize the interactions between species. The CM population density (0,09 ind/ha) was higher than that of the golden lion tamarin (0,06 ind/ha). The mean association index between tamarins and marmosets varied among groups and seasons (winter=62% and summer=35%). During the winter, competition resulted in increases in territorial and foraging behavior when associated with marmosets. Evidence of benefits...

The objective of the present study was to determine if the acute behavioral effects of cocaine acutely administered intraperitoneally (ip) at doses of 5, 10 and 20 mg/kg on white male CF1 mice, 90 days of age, would be influenced by leptin acutely administered ip (at doses of 5, 10 and 20 µg/kg) or by endogenous leptin production enhanced by a high-fat diet. The acute behavioral effects of cocaine were evaluated in open-field, elevated plus-maze and forced swimming tests. Results were compared between a group of 80 mice consuming a balanced diet and a high-fat diet, and a group of 80 mice fed a commercially available rodent chow formula (Ralston Purina) but receiving recombinant leptin (rLeptin) or saline ip. Both the high-fat-fed and rLeptin-treated mice...

Behavioral Economics, Food Assistance, and Obesity
Provedor de dados: 31
Autores: Just,   David R.
While there is mixed evidence of the impact of food assistance programs on obesity, there is general agreement that the food-insecure are at higher risk of obesity and obesity-related diseases. Food assistance programs, originally designed to overcome a lack of available food, now need to confront a very different problem: how to provide for the food-insecure while encouraging healthy lifestyles. This paper examines the potential to address these competing needs using traditional economic policies (manipulating information or prices) versus policies engaging behavioral economics and psychology.

Autores: Langford, F; Rutherford, K; Sherwood, L; Jack, M; Haskell, M.
There is an increasing number of organic dairy farms in the UK. The aim of this study is to compare behaviour of dairy cows on organic and non-organic farms. Twenty organic and 20 non-organic farms throughout the UK were visited over two winters (2004/05 and 2005/06). Organic and non-organic farms were paired for housing type, herd size, milk production traits and location. The number of cows feeding was counted every fifteen minutes for 4.5 h after new feed was available post morning milking. Behaviour at the feed-face was recorded for 60 minutes and aggressive interactions between cows were quantified. Farm type had no effect on numbers of cows feeding. There were more interactions between cows feeding at open feed-faces compared to head-bale barriers....

Behavioural responses of captive-born greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae) submitted to antipredator training
Provedor de dados: 104
Autores: Azevedo,Cristiano S. de; Young,Robert J.
Human activities have been diminishing greater rhea Rhea americana (Linnaeus, 1758) populations throughout their natural distribution. The reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintroduced were killed by predators. Captive-born animals that have been isolated from predators for many generations can lose their predator recognition abilities. To enhance the survival rates of the reintroduced animals, researchers are now using antipredator training techniques. We studied the response of 15 zoo-borne greater rheas to antipredator training. The animals were divided into three groups: two test groups and one control group. We ran 15 antipredator tests and four control testes with each group....

Ziel des Projektes war die Erarbeitung eines Verfahrens zur Regulierung der Blutlaus (Eriosoma lanigerum), eines wirtschaftlich bedeutenden Schädlings im ökologischen Obstbau, gegen den es momentan keinerlei wirksame Bekämpfungsmöglichkeiten gibt. Hierzu wurde versucht, aus der Erfahrung vorangegangener Versuchsergebnisse ein Verfahren zur Bekämpfung der Blutlaus durch den Einsatz von Blutlauszehrwespen (Aphelinus mali) aus einer Nützlingszucht zu entwickeln und zur Praxisreife zu bringen. Die Zehrwespe ist ein natürlich vorkommender Gegenspieler, dem es aufgrund mangelnder Synchronisation zwischen Schädling und Nützling nicht rechtzeitig gelingt, den Schaden durch die Blutlaus zu verhindern. 2004 konnten mit dem Einsatz von parasitierten Blutlausmumien...

Belostoma dilatatum (Dufour) (Hemiptera, Belostomatidae) hosting metacercariae of Stomylotrema vicarium Braun (Digenea, Stomylotrematidae) in southern Brazil
Provedor de dados: 104
Autores: Amato,Suzana B.; Amato,José F. R.
Giant water bugs (aquatic Heteroptera), Belostoma dilatatum (Dufour, 1863), were collected in rice plantation water canals, in the Municipality of Eldorado do Sul, outskirts of Porto Alegre, State of Rio Grande do Sul, southern Brazil. Five specimens were dissected with the objective of finding metacercariae of digenetic trematodes. Four of them (80%) were positive for metacercarial cysts of Stomylotrema vicarium Braun, 1901. The intensities of infection varied from 1 to 16 metacercariae per host (average 7.6). The cysts were whitish, translucent, and found loose among the viscera, in the abdominal and thoracic cavities. Belostoma dilatatum is a new host record for metacercarial cysts of stomylotrematid digenetic trematodes and this is the first time that...

Benchmarking in Tourism Destination, Keeping in Mind the Sustainable Paradigm
Provedor de dados: 31
Autores: Bosetti,   Valentina; Cassinelli,   Mariaester; Lanza,   Alessandro.
Tourism destination benchmarking and the assessment of tourism management performances are a crucial and challenging task in the direction of evaluating tourism sustainability and reshaping tourism activities. However, assessing tourism management efficiency per se may not provide enough information concerning long-term performances, which is what sustainability is about. Natural resources management should therefore be included in the analysis to provide a more exhaustive picture of long-run sustainable efficiency and tourism performances. Indeed, while the environmental endowment of a site is a key feature in tourism destination comparison, what really matters is its effective management. Therefore, in this paper we assess and compare tourism...

Provedor de dados: 14
Autores: MARTHA JUNIOR, G. B.; BARCELLOS, A. de O.; VILELA, L.; SOUSA, D. M. G. de.
Esses sistemas de integração lavoura-pecuária demandam recursos para investimentos e custeio, capacitação técnica e qualificação gerencial para a obtenção de benefícios da tecnologia. O processo de administração e de tomada de decisão em relação à incorporação de qualquer tecnologia no sistema depende do perfeito entendimento das inter-relações entre recursos, atividades e influências externas que compõem e determinam o sistema de produção. O presente trabalho contribui para o melhor entendimento e análise dos processos envolvidos na integração lavoura-pecuária, tornando-se referência importante para estudantes, produtores e técnicos que buscam uma introdução geral ao tema.

Benthic copepod communities associated with tubeworm and mussel aggregations on the East Pacific Rise
Provedor de dados: 5
Autores: Gollner, S; Zekely, J; Van Dover, C; Govenar, B; Le Bris, Nadine; Nemeschkal, H; Bright, M.
Variability in the structure of the meiobenthic copepod communities was studied among three vent sites on the East Pacific Rise. One of the sites was dominated by the mussel Bathymodiolus thermophilus, and the other two of the sites were dominated by the tubeworm Riftia pachyptila. In addition to the differences in the dominant megafauna, the maximum temperatures were much lower at the mussel-dominated sites, and the temperature to sulfide ratio was different between the tubeworm-dominated sites. A total of 22 vent endemic siphonostomatoid copepod species and 5 harpacticoid copepod species were identified among the three sites. Copepod abundance was low at all sites (&lt; 1 - 31 ind. 10 cm(-2)). Species richness ranged from 6 - 14, Shannon-Wiener diversity...

Autores: Mojtahid, Meryem; Jorissen, Frans; Durrieu, Josiane; Galgani, Francois; Howa, Helene; Redois, Fabrice; Camps, Roger.
We present a study of benthic foraminiferal. faunas from the outer continental shelf off Congo (tropical West Africa), with the aim to determine the impact of the discharge of oily drill cuttings on the sea floor environment, to judge the regenerating capacity of the benthic ecosystem, and to investigate the possibility to develop an environmental monitoring method for open marine continental shelf environments, based on benthic foraminifera. We studied the spatial distribution and microhabitats of living and dead foraminiferal faunas, sampled in April 2003, 4 years after the end of disposal activities, in the upper 3 cm of the sediment at 9 stations (about 180 m depth) offshore Congo, that were subject to various degrees of pollution by oily cuttings from...

Beschermingsplan moerassprinkhaan &amp; zompsprinkhaan in Gelderland

Beschermingsplan moerassprinkhaan &amp; zompsprinkhaan in Gelderland  Sprinkhanen en krekels horen tot de best bekende insecten van Nederland. Sommige soorten sprinkhanen breiden zich in rap tempo uit (sikkelsprinkhaan, zuidelijk spitskopje) en recent zijn zelfs weer nieuwe soorten voor de Nederlandse fauna gevonden (lichtgroene sabelsprinkhaan, boomkrekel). Het lijkt daarmee goed te gaan met de Nederlandse sprinkhanen, maar tegenover de nieuwkomers staan diverse soorten die bedreigd zijn of zelfs al uit Nederland zijn verdwenen. In tegenstelling tot de weinig kieskeurige nieuwkomers zijn de bedreigde soorten aangewezen op bijzondere habitats. Het voorliggende beschermingsplan voor de provincie Gelderland richt zich op twee van de bedreigde soorten van...

Best Response to GMOs in Developing Countries
Provedor de dados: 31
Autores: Luc,   Veyssiere.
This article examines the dilemma of a large exporting Country for an agricultural product having to determine its domestic agricultural policy as well as its level of IPRs enforcement. The analysis explicitly considers the possibility of two frauds by farmers: mislabeling of GM products as conventional and smuggling of illegal GM seeds. In doing so this paper makes two points: the approval decision of the products of the biotechnology is speci…c to the labeling regime and a large country has always an incentive to enforce its IPR regime.

The fixation and transformation of atmospheric dinitrogen into ammonia and hence into organic e compounds is a crucial part of the nitrogen cycle. Nitrogenase, the enzyme responsible, has a wide taxonomie distribution in the bacteria and archaea, but is confined to a limited number of species. Among these, rhizobia, whieh form nodules on the roots of legumes, are recognised as the main contributors of biologieally-fixed nitrogen. Until recently, it has been generally accepted that legumes are nodulated exelusively by members of the alfa-proteobaeteria belonging to a number of related genera in the family Rhizobiaceae. In this document we review some results from recent studies that presents the newly-discovered beta-rhizobia which challenge the accepted...

Autores: Francksen,   Tammo; Latacz-Lohmann,   Uwe.
This paper employs Data Envelopment Analysis and Stochastic Frontier Analysis to examine the technical efficiency of the agricultural sectors of the Central and Eastern European accession Countries (CEECs) during the period 1998-2001. The results indicate that the agricultural sectors of many accession countries are both technically inefficient and scale-inefficient. The analysis of changes in total factor productivity suggests slow rates of adoption of technical progress, declining technical efficiency of agricultural enterprises and, as a result, less efficient use of existing technologies and resources during the considered time period.

Beyond Organic: An Overview of Biodynamic Agriculture with Case Examples
Provedor de dados: 31
Autores: Phillips,   Jon C.; Rodgriguez,   L. Pilar.
A great deal of research has been done regarding economic and consumer aspects of organic agriculture. A different form of agriculture, called biodynamic agriculture, is emerging, with acreage located across the globe. Like organic agriculture, biodynamic agriculture has a certification process, but it has not received as much research attention from agricultural economists. This paper provides basic background information about biodynamic agriculture. In particular, it gives a count of certified biodynamic farms, by state, in the U.S., and it gives the most common products produced by those farms. Wine grapes are by far the most common biodynamic agricultural product. It also includes three case examples of firms employing this production system and...

Beyond retrovirus infection: HIV meets gene therapy
Provedor de dados: 74
Autores: Silva,Flávia Helena da; Dalberto,Tiago Pires; Nardi,Nance Beyer.
The human immunodeficiency virus (HIV) is classified as a retrovirus because of its RNA genome and the fact that it requires reverse transcriptase to convert it into DNA. This virus belongs to the lentivirinae subfamily and is able to infect quiescent cells but is better known for its association with acquired immunodeficiency syndrome (AIDS) and can be described as one of the most effective vectors for gene transfer. Biosafety concerns are present whenever viral vectors are employed but are particularly pertinent to the development of HIV-based vectors. Insertional mutagenesis and the production of new replication-competent viruses (RCV) have been pointed to as major problems, but experimental data have shown that safe protocols can be developed for their...

Beyond taxonomy: prospects for understanding morphological diversity in the grasses (Poaceae)
Provedor de dados: 66
Autores: Kellogg,Elizabeth A.
The grass family (Poaceae) is unusually well known taxonomically, with over 10,000 described species. These are characterized and classified according to a variety of morphological characters, particular those of the inflorescence and the spikelet but also a wealth of micromorphological and moleculary characters. Much data on the family is accessible electronically. Available phylogenies have identified 12 major lineages that are classified as subfamilies; within these subfamilies, especially for subfamily Panicoideae, the phylogeny is becoming increasingly clear. Developmental studies focus on the activity and fate of meristems throughout the plant, and illustrate how adult morphology arises. Analyses of quantitative trait loci (QTL) verify that some...

Bezafibrate for the treatment of hypertriglyceridemia in HIV1-infected patients on highly active antiretroviral therapy
Provedor de dados: 55
Autores: Geraix,Juliana; Souza,Micheli Evangelista de; Delatim,Francieli Cristina; Pereira,Paulo Câmara Marques.
The use of highly active antiretroviral therapy (HAART) in HIV-infected patients has been associated with the development of risk factors for cardiovascular diseases (CD) including dyslipidemia and insulin resistance, hypertriglyceridemia being the most frequent metabolic disturbance in these patients. Fibrates are indicated when hypertriglyceridemia is accentuated and persists for over six months. We evaluated the efficacy and safety of bezafibrate for the treatment of hypertriglyceridemia in HIV-infected individuals on HAART. All patients received 400mg/day of bezafibrate and were evaluated three times: Mo (pre-treatment), M1 (one month after treatment), and M2 (six months after treatment). Fifteen adult individuals, eight males and seven females with...

Bias and Efficiency of Uniform Bid Design in Contingent Valuation
Provedor de dados: 31
Autores: Kim,   Sooil.
While contingent valuation (CV) methods have experienced growing popularity for estimating the willingness to pay for nonmarket goods and services, optimal bid designs for CV that provide guidance in bid point placement often render themselves impractical by relying on pretest or prior information about the true distribution for willingness to pay.  We investigate the use of a practical alternative to existing optimal or robust bid designs called the uniform design. Uniform design randomly draws bid points from a predetermined uniform distribution. Analytics and simulations show that the uniform design has higher low-bound of relative efficiency at 84 percent of D-optimum than a robust design. Simulations also demonstrate that uniform design outperforms...

An analysis of peer reviews of 84 organic farming grant applications, submitted to The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS) in 2001 was carried out to investigate whether peer reviews were influenced by the peer reviewers’ affiliation to organic agriculture research and to what degree peer reviewers distinguish between scientific quality and societal relevance. Fifteen reviewers were grouped in three groups (1) scientists with affiliation to organic farming research, (2) scientists without affiliation to organic farming research and (3) users of the research. The scientist groups assessed societal relevance of the grant applications and scientific quality as a sum of three scientific criteria and the...

Bi-cropping fodder maize in an existing (grass)clover sward
Provedor de dados: 21
Autores: Prins, U.; Eekeren, N. van; Oomen, G.J.M.
Organic cultivation of fodder maize is still considered to be difficult. Weed pressure, soil structure degradation during harvest and low nutrient efficiency are some of the common problems. Directly sowing maize in a (grass)clover sward using special-ized drilling machines can solve these problems. In a bi-cropping experiment under organic conditions we found similar yields as the reference treatment (ploughing) when the maize was sown in a clover sward, the roots of the remaining sward were cut one week after sowing and an additional fertiliser was applied.

Bid Design and its Influence on the Stated Willingness to Pay in a Contingent Valuation Study
Provedor de dados: 31
Autores: Carmona-Torres,   Carmen; Calatrava-Requena,   Javier.
The CV method estimate the monetary value that specific changes in the provision of goods and services represent for society, which is asked for their Willingness To Pay (WTP) for it, according to their budget and individual preferences, in a survey. The applications of CV are a source of information to important public decision-making. Therefore, it seems to be a desirable objective for a CV study to strive to detect and reduce, as far as possible, the bias affecting the elicited values. In the present work, the starting point bias in an application to the case study of the conservation of the Iberian Lynx in Spain is analyzed. This bias is caused by the potential influence of the bid values offered to the interviewees on their stated preferences. Three...

Created in 1992, the REPAMO network (Network of mollusc pathology), is a national zoosanitary surveillance network of shellfish health status along the French coasts. Ils activities are in keeping with two European Directives, 91167/EEC and 95170/EC and are a part of the institutional tasks of Ifremer. The aims of the network are to prevent the introduction and spread of exotic pathogens and to sm'vey 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 (Granville bed and zone X). In 2005, only samples of the Granville bed could be analysed due to the difflculty to obtain flat oysters (sparse oyster beds, beds...

Bilan du suivi de l'exploitation industrielle de la crépidule en Bretagne Nord (baies de Saint-Brieuc et du Mont Saint-Michel) 2002-2005
Provedor de dados: 5
Autores: Blanchard, Michel; Hamon, Dominique.
The slipper-limpet (Crepidula fornicata) is a marine gastropod which causes serious perturbations in shellfish beds, because of spatial spreading and density rising. Along French coasts, in Northern Brittany, two bays are highly colonized : bay of Saint-Brieuc, centre for scallops fishery, and bay of Mont-Saint-Michel, a famous oyster-farming area, with a total limpet stock about 450 000 metric tons. The association AREVAL was founded in 2001 to manage there, an industrial collect of limpets by a succing-dredge, followed ashore by a treatment for calcareous soil improvement. The scientific survey, contracted to IFREMER, included measurements of long andshort-term dredge's effects on grounds and limpet population, and proposals to set up dredging...

Bilateral Commitment

Autores: Bade,   Sophie; Haeringer,   Guillaume; Renou,   Ludovic.
We consider non-cooperative environments in which two players have the power to commit but cannot sign binding agreements. We show that by committing to a set of actions rather than to a single action, players can implement a wide range of action profiles. We give a complete characterization of implementable profiles and provide a simple method to find them. Profiles implementable by bilateral commitments are shown to be generically inefficient. Surprisingly, allowing for gradualism (i.e., step by step commitment) does not change the set of implementable profiles.

Bio allein macht nicht gesünder. Aber Bioprodukte sind Bestandteil eines nachhaltigen und gesunden Ernährungsstils. Die meistgenannten Erwartungen von Konsumentinnen und  Konsumenten an Bioprodukte lassen sich wie folgt zusammenfassen: keine Pestizidrückstände, besserer Geschmack, besser für Gesundheit und Umwelt. Ein Überblick über die verfügbare Fachliteratur zeigt, dass Bioprodukte diese Erwartungen meist erfüllen. Die Frage, wie sich die gefundenen Unterschiede auf die menschliche Gesundheit auswirken, ist jedoch experimentell noch wenig erforscht.

Bio Suisse Bans Hybrid Cereals
Provedor de dados: 21
Autores: Arncken, Christine; Schmid, Otto.
On April 19th, 2006, the 100 delegates of Bio Suisse, the Swiss organic umbrella organization, voted to ban Hybrid varieties in organic cereals (except maize). This decision primarily concerns rye. Organic rye is grown on only 250 ha, about 20% of which is sown to hybrid varieties at present. About 60% of total organic demand is imported. Hybrid varieties of the other cereals are not yet being grown. The delegates decided that it is time to act now to send a signal to breeders and to the international organic community before the alternatives to hybrids vanish.

In this work, mercury (Hg), copper (Cu) and zinc (Zn) concentrations and tissue distribution are determined in seven benthic invertebrates species (the key species) from the Mid Atlantic Ridge (MAR) hydrothermal vent fields. The samples were collected from three hydrothermal vent fields - Menez Gwen, 840 m;, Lucky Strike, 1700 m and Rainbow, 2300 m - near the Azores Triple Junction. These fields are characterized by different depths, geological context and chemical composition of the hydrothermal fluid, particularly the metal content, which is reflected by the metal concentrations in the organisms. Indeed, our results show that organisms from Menez Gwen presented the highest Hg concentrations, while those from Lucky Strike and Rainbow were richer in Cu and...

The aim of this study was to evaluate the effects of the processing stages of yerba maté (Ilex paraguariensis) on the moisture content of the leaves and the efficiency of the aqueous extraction of some bioactive substances. Samples of yerba maté were analyzed for caffeine, phenolic acids (caffeic acid, 5-caffeoilquinic acid) and flavonoids (quercetin, kaempferol and myricetin) by HPLC equipped with a diode array detector. Processing widely influenced the caffeine and 5-caffeoilquinic acid content of the aqueous extract (p &lt; 0.05), which was related to the moisture content of the leaves. Caffeic acid was present in 45% of the in infusions from dried mate leaves. Quercetin, myricetin and kaempferol were not detected.

Phosphorus fertilizers are essential to obtain high productivity, however, they contain heavy metals that can contaminate the soil and threat the health of animals and humans. The present study focused the determination of Cd and Pb concentrations in different phosphorus fertilizers as well as the absorption of these heavy metals by velvet green bean grown on soil amended with such fertilizers. The experiment was set up as a completely randomized design in a factorial scheme. The factors were four phosphorus sources (triple superphosphate-TS, Yorin thermophosphate-YT, Araxa rock phosphate-AP, and Gafsa rock phosphate-GP) applied at five rates (0, 92, 183, 275, and 366 kg ha-1 of P2O5).

Biochemical and biological properties of Lonomia obliqua bristle extract
Provedor de dados: 80
Autores: Chudzinski-Tavassi,A. M.; Carrijo-Carvalho,L. C.
Lonomia obliqua caterpillar is frequently seen in accidents with humans especially in the south of Brazil. Patients develop a hemorrhagic syndrome that can be treated with specific antilonomic serum. A consumptive coagulopathy was found to be the main cause of bleeding complications observed in patients after contact with L. obliqua. Studies revealed that L. obliqua caterpillar bristle extract (LOCBE) displays a procoagulant activity that leads to intravascular thrombin formation, resulting in a special form of disseminated intravascular coagulation (DIC). Fibrinolysis seems to be secondary to the fibrin production, since no direct fibrinolytic activity was found in LOCBE. Two procoagulant toxins, a factor X activator (Losac) and a prothrombin activator...

Many toxins from scorpion venoms cause neurotransmitters release by activating the autonomic system. The aim of the present work was to determine osmotic fragility of red blood cells (RBCs) and serum biochemical changes produced by the venom of Odonthobuthus doriae (O. doriae), a dangerous species of scorpion in Iran. For this study we selected 2 groups, each one containing 10 New Zealand white rabbits weighing 2 ± 0.2 kg. In vivo and in vitro osmotic fragilities as well as packed cell volume (PCV) were determined. Serum was separated and used for determination of glucose, blood urea nitrogen (BUN), creatinine, uric acid (UA), triglycerides, cholesterol, aspartate aminotransferase (AST, EC 2.6.1.1), and alanine aminotransferase (ALT, EC 2.6.1.2).

The objective of this work was to evaluate biochemical parameters in Paracoccidioides brasiliensis infected mice and the effect of Canova medicine on these parameters. Mice infected with the isolate Paracoccidioides brasiliensis Pb18 and treated with Canova for 17 weeks were used. The biochemical parameters analysed were the levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and amylase, and the concentration of total proteins, albumin and globulins. The results suggested that the animals that were treated with Canova had less functional alterations in their internal organs.

Exposing a wild-type culture of Trichoderma harzianum to gamma irradiation induced two stable salt-tolerant mutants (Th50M6 and Th50M11). Under saline conditions, both mutants greatly surpassed their wild type strain in growth rate, sporulation and biological proficiency against Fusarium oxysporum, the causal agent of tomato wilt disease. Tolerant T. harzianum mutants detained a capability to grow and convinced sporulation in growth media containing up to 69 mM NaCl. In comparison with their parent strain, characterization of both mutants confirmed that they have reinforced contents of proline and hydroxyproline, relatively higher sodium content compared to potassium, calcium or magnesium contents, higher level of total phenols.

The increasing expansion of agro-industrial activity has led to the accumulation of a large quantity of lignocellulosic residues all over the world. In particular, large quantities of rice straw (300.000 t) and citric bagasse (50.000 t) are annually produced in Uruguay. In this work we present the study of the bioconversion of these substrates with the edible mushroom Pleurotus spp so as to increase nutritional values and digestibility for its use as animal feed. The SSF process was optimized and the products after different periods of mushroom growth were evaluated. The microbial counts (cfu/g) for the inoculated substrates 44 days after incubation were 15 x 10(4), &lt; 10 and &lt; 10 for aerobic microorganisms, coliforms and E. coli, respectively. After...

Biodegradation of reactive textile dyes by basidiomycetous fungi from brazilian ecosystems
Provedor de dados: 58
Autores: Machado,Kátia M.G.; Compart,Luciana C.A.; Morais,Rúbio O.; Rosa,Luiz H.; Santos,Mércia H.
The potential of Trametes villosa and Pycnoporus sanguineus to decolorize reactive textile dyes used for cotton manufacturing in the State of Minas Gerais, Brazil, was evaluated. Growth and decolorization halos were determined on malt extract agar containing 0.002g L-1 of the dye. T. villosa decolorized all 28 of the tested dyes while P. sanguineus decolorized only 9. The effect of culture conditions (shaking and dye and nitrogen concentration) on the degradation of Drimaren Brilliant Blue dye was evaluated during growth of the fungi in liquid synthetic medium. Shaking favored degradation and decolorization was not repressed by nitrogen. In pure culture, T. villosa and P. sanguineus decolorized synthetic effluent consisting of a mixture of 10 dyes. Higher...

Biodegradation of remazol brilliant blue R by ligninolytic enzymatic complex produced by Pleurotus ostreatus
Provedor de dados: 58
Autores: Machado,Kátia Maria Gomes; Matheus,Dácio Roberto.
Pleurotus ostreatus ("shimeji") is produced in Brazil on a commercial scale using various lignocellulosic residues. Efforts have been made to reuse the culture residue to obtain products of greater aggregate value such as enzymes or in processes of bioremediation. We evaluated the Remazol brilliant blue R (RBBR) degradation potential of extracts from solid substrate colonized by P. ostreatus and extracts from residue of the "shimeji" mushroom yield. Colonized substrates and residue were provided by Toyobo do Brasil Ltda. Extraction was performed with sodium acetate buffer (50 mM, pH 4.6). RBBR decolorization was monitored at 592 nm and peroxidase and laccase activities were measured by monitoring the oxidation of ABTS. Horseradish peroxidase was used as...

Biodiversity and sustainable management of a tropical wetland lake ecosystem: A case study of Lake Kanyaboli, Kenya
Provedor de dados: 20
Autores: Rasowo, J.O.; Abila, R.; Manyala, J.
Lake Kanyaboli and the surrounding Yala swamp wetland has been recognized as an important biodiversity hotspot. Recent population genetic and phylogenetic studies confirm the evolutionary importance of Lake Kanyaboli (Kenya) 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 changes within the swamp threaten the ecological integrity and functioning of this highly dynamic wetland ecosystem. It is therefore imperative that proper management and...

Autores: Biagi,Renata; Meireles,Andrea L.; Mantelatto,Fernando L.
In southern Atlantic studies on hermit crab biology are scanty considering the local biodiversity. In this way, some population features of Paguristes calliopsis Forest and Saint Laurent, 1968 such as size frequency distribution, sex ratio and shell occupation in the natural environment were studied. Specimens were collected by means of scuba methods in the infralittoral area of the Anchieta Island. A total of 116 individuals were analyzed. Size measurements (minimum; maximum; mean shield length ± sd, respectively) were 0.8; 4.5; 2.76 ± 0.79 mm for males and 2.28 ± 0.36 mm for females. The sex ratio was 1.47:1 in favor of males which prevailed in the largest size classes. The hermit crabs occupied shells from eleven gastropod species and Cerithium atratum...

Myocardial contrast echocardiography has been used for assessing myocardial perfusion. Some concerns regarding its safety still remain, mainly regarding the induction of microvascular alterations. We sought to determine the bioeffects of microbubbles and real-time myocardial contrast echocardiography (RTMCE) in a closed-chest canine model. Eighteen mongrel dogs were randomly assigned to two groups. Nine were submitted to continuous intravenous infusion of perfluorocarbon-exposed sonicated dextrose albumin (PESDA) plus continuous imaging using power pulse inversion RTMCE for 180 min, associated with manually deflagrated high-mechanical index impulses. The control group consisted of 3 dogs submitted to continuous imaging using RTMCE without PESDA, 3 dogs...

Biogas in organic agriculture: Effects on yields, nutrient uptake and environmental parameters of the cropping system
Provedor de dados: 21
Autores: Möller, Kurt; Stinner, Walter; Leithold, Günter.
System effects of biogas fermentation in organic cropping systems with and without livestock (dairy farming) were investigated from 2002-2005. In both systems no differences in yields and nutrient uptake were detected in the legume crops. In the livestock-system non legume crops of the slurry system had no higher yields but a higher nitrogen uptake (6 %) than the stable manure system. Slurry-fermentation had no effect on yields and nitrogen uptake. The inclusion of crop residues in the fermentation system increased the nitrogen uptake about by 10 % and reduced the nitrate leaching potential by ca. 10 %. The inclusion of external substrates lead to a further increase in nitrogen yield of 10 %, but to no significant increase in dry matter yields....

Autores: VÁSQUEZ-DEL CARPIÓ,RODRIGO; MORALES,JAIME L; BARRO,MARIO; RICARDO,ALBA; SPENCER,EUGENIO.
Rotaviruses are the major cause of acute gastroenteritis in infants world-wide. The genome consists of eleven double stranded RNA segments. The major segment encodes the structural protein VP1, the viral RNA-dependent RNA polymerase (RdRp), which is a minor component of the viral inner core. This study is a detailed bioinformatic assessment of the VP1 sequence. Using various methods we have identified canonical motifs within the VP1 sequence which correspond to motifs previously identified within RdRps of other positive strand, double-strand RNA viruses. The study also predicts an overall structural conservation in the middle region that may correspond to the palm subdomain and part of the fingers and thumb subdomains, which comprise the polymerase core of...

A biologia da tuvira, Gymnotus cf. carapo, por seu grande uso como isca viva para a pesca esportiva, foi estudada no baixo rio Negro, onde é coletada pelos isqueiros, pescadores especializados nesse tipo de pescaria. Foram estudados os aspectos relativos à reprodução, alimentação e crescimento, bem como as interrelações com os fatores abióticos. As metodologias utilizadas foram as usuais nesse tipo de pesquisa. É uma espécie que possui respiração aérea acessória, o que lhe permite viver em ambientes quase anóxicos, freqüentados por poucas espécies de peixes. A reprodução ocorre de dezembro a fevereiro/abril de cada ano, com a chegada da inundação na planície. Possui desova parcelada e de acordo com a literatura, os machos escavam o fundo, onde as fêmeas...

Autores: Aguiar,Cândida M. L.; Garófalo,Carlos A.; Almeida,Gesline F.
O comportamento de nidificação de Centris (Hemisiella) trigonoides Lepeletier, 1841, e o comportamento de seus cleptoparasitas foram estudados em Monte Santo, Bahia, Brasil. As abelhas construíram seus ninhos com uma mistura de solo e óleo, dentro de cavidades preexistentes na madeira de uma construção abandonada, assim como em gomos de bambu de 8 e 9 mm de diâmetro. Os ninhos completados tinham de uma a cinco células alongadas, arranjadas em uma série linear e orientadas horizontalmente. O tempo gasto para construir uma célula foi altamente variável, sendo em geral de 4,5 a 5,5 h. Após finalizar a construção da célula, as fêmeas fizeram uma ou duas viagens para coletar um líquido incolor, provavelmente óleo floral, usado para revestir as paredes internas...

Biological and molecular characterization of Streptococcus crista strains isolated from human dental biofilm by means of arbitrary primers - PCR (AP-PCR)
Provedor de dados: 58
Autores: Angelini,Michelle; Silveira,Wanderley Dias da; Campos,Tatiana Amabile de; Cai,Silvana; Castro,Antonio Fernando Pestana de.
Streptococcus ssp are important components of the dental biofilm and Streptococcus crista is considered to be an interesting model of bacterial interactions taking place in this biofilm. In the present work, S. crista strains were isolated from the dental biofilm of Brazilian individuals and studied with respect to their biological characteristics and their molecular profile by means of AP-PCR techniques, using the RR2, 434, OPR2, OPR8, and OPR13 primers. Results allowed us to build a similarity dendrogram. Analysis of the similarity dendrogram allowed the separation of the studied strains into similarity groups. All isolates presented fibril tufts by Transmission Electron Microscopy (TEM). These isolates were able to bind to salivary amylase and to adhere...

Biological Control in Organic Production: First choice or last option?
Provedor de dados: 21
Autores: Speiser, Bernhard; Wyss, Eric; Maurer, Veronika.
"Biological agriculture" is a synonym for organic farming, but the term was developed independently from ‘biological control’. Therefore, it cannot be taken for granted that all methods of biological control are acceptable or even a first choice in organic farming. In this chapter, we explore the attitude of organic farming towards methods of biological control. Although organic farming has become popular during the last decade, organic farms are still a minority in all countries.     Furthermore there is a lack of profound knowledge about the regulatory framework for organic farming (i.e. public regulations and private standards). Therefore, we will firstly give a brief introduction to organic farming.

Biological control of the cherry fruit fly, Rhagoletis cerasi L. (Diptera, Tephritidae)  by use of entomopathogenic nematodes: first experiences towards practical  implementation.
Provedor de dados: 21
Autores: Herz, Annette; Köppler, Kirsten; Vogt, Heidrun; Elias, Ellen; Peters, Arne; Katz, Peter.
The use of entomopathogenic nematodes (EPN) is a promising approach to control the cherry fruit  fly, Rhagoletis cerasi L.. We already demonstrated the high potential of EPN to infect larvae after  leaving the cherry for pupation in the soil in laboratory and field experiments. For practice, an application  technique is needed, that is both, grower- and EPN friendly. We tested a tractor mounted  spray boom for treatment under the canopy area. The achieved rate of EPN in the soil met the expectations.  The activity of EPN in soil samples was high after application, but dropped to 60% of the  initial activity within one week. Exact forecasting of larval drop from cherries is another major challenge.  To obtain basic data, we recorded the phenology of...

Bacillus species can form endospores and have broad-spectrum activity of their antibiotics. For that reason, they offer several advantages over other bacteria for protection against root pathogens. This work was intended to determine the ability of Bacillus spp. to inhibit Verticillium dahliae. First, antagonistic activities of Bacillus spp. were studied in greenhouse trials. These results suggest that the bacterium can control soil-borne diseases. Secondly, to investigate the situation in a culture environment, Bacillus spp. were examined for their activity to control Verticillium black spot of Japanese radish and plant-growth promotion rhizobacteria (PGPR) effects in a field. After 2 months, these bacteria reduced Verticillium black spot of Japanese...

Autores: Hetebrügge, K.; Fieger-Metag, N.; Kienzle, J.; Bathon, H.; Zebitz, C.P.W.; Zimmer, J.
The release of Aphelinus mali HALD. from artificial rearing for the control of Woolly Apple Aphid (Eriosoma  lanigerum HAUSM.) was tested in field trials. The release of adults proved to be more suitable than the release  of cards with parasitized mummies as practised in the first trial. Setting free adult A. mali at the beginning of  June reduced the aphid population, though its efficiency was not high enough to prevent damage of the trees  totally. The practical applications of A. mali in early spring (after blossom) were not effective because climatic  conditions were not suitable enough. The fertility of A. mali depends on temperature and light intensity.  The application of Micula (rape oil) and T-S forte reduced the growth of the aphid population...

Biological Invasions: The Case of Soybean Aphid Infestation
Provedor de dados: 31
Autores: Kim,   C.S.; Schaible,   Glenn D.; Garrett,   Lynn; Lubowski,   Ruben N.; Lee,   Donna J.
Soybeans, the second highest cash crop following corn in the U.S., have come under attack by invasive species, the soybean aphid from the North and soybean rust from the South.  We estimated the economic losses resulting from soybean aphid infestation by using a dynamic equilibrium model.  Results indicate that, first, the reduction of soybean production resulting from soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to the domestic demand.  Second, the economic losses to U.S. soybean producers would grow on average annually between $12.8 million and $23.4 million during the first five years of infestation.  In the longer-run, soybean producers would suffer greater...

Biological, nutritional, and histochemical basis for improving an artificial diet for Bracon hebetor Say (Hymenoptera: Braconidae)
Provedor de dados: 82
Autores: Magro,Sandra R.; Dias,Alcides B.; Terra,Walter R.; Parra,José R.P.
The biology of Bracon hebetor Say (Hymenoptera: Braconidae) reared on fifth instars of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) (natural diet) and in vitro (artificial diet) was evaluated. Data on the number of instars, development time and food intake were collected, and histochemical tests were conducted to detect proteins and lipids in the parasitoid's digestive tract. The data disclosed differences that can help to improve artificial rearing of B. hebetor. B. hebetor had three instars in both diets, but the developmental time on the artificial diets was prolonged due to the increase in larval and pupal development times. Larvae grew faster on the natural host and required a lower food intake (2.7 µl) as compared to that required by the...

Biologically fixed N2 as a source for the N2O production in a grass clover mixture, measured by 15N2
Provedor de dados: 21
Autores: Carter, Mette S.; Ambus, Per.
The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures of white clover and perennial ryegrass were incubated for 14 days in a growth cabinet with a 15N2-enriched atmosphere (0.4 atom% excess). Immediately after labelling, half of the grass-clover pots were sampled for N2 fixation determination, whereas the remaining half were examined for emission of 15N labelled N2O for another eight days using a static chamber method. Biological N2 fixation measured in grass-clover shoots and roots as well as in soil constituted 342, 38 and 67 mg N m-2 d-1 at 16, 26 and 36...

Autores: Brandt, Kirsten; Lück, Lorna; Schmidt, Christoph; Seal, Chris; Leifert, Carlo.
The greatly increased market share of organic food, has prompted increasing interest in investigating whether there are actual differences in the effects of organic and conventional food on health. Previous studies have focussed on composition analyses and have therefore not been able to provide definitive proof for differences between these two food production systems in terms of long-term impact on human health. Also the designs of some of these studies were inadequate to provide proof for definite composition differences. There are virtually no human dietary intervention and cohort studies, which can provide definite proof for potential health impacts.  When taking into account the present knowledge in nutrition, toxicology, physiology and ecological...

Biology and fertility life table of Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) in sugarcane
Provedor de dados: 63
Autores: Garcia,José Francisco; Botelho,Paulo Sérgio Machado; Parra,José Roberto Postali.
Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is the most important pest of sugarcane harvested without the use of fire to burn leaf trash. Its biology was studied for three generations in order to obtain basic information about its life cycle. A fertility life table was used to evaluate the quality of laboratory-reared insects. Data were obtained at a temperature of 25 ± 1ºC, RH of 70 ± 10%, and a 14-hour photophase. The incubation period lasted 21 days with a viability of 81%; the nymph stage had a duration of 37 days, with a 94% viability; the male and female longevities were 18 and 23 days, respectively, with a pre-oviposition period of 5 days and an oviposition period of 16 days, with a fecundity of 342 eggs, with a life-cycle (egg-adult) of 60...

Autores: El-Ganainy, A. A.; Sabrah, M. M.; Zaky, M. A.
Some biological aspects of the pufferfish Lagocephalus sceleratus were studied and correlated with the toxicity of the fish. A sample of 176 fish with total lengths ranging from 18.5 to 78.5 cm were collected from commercial catches at the Attaka fishing harbor between October 2002 and June 2003. Length weight regression parameters for males, females and all individuals were estimated. Modal progression analysis output indicates ten distinct age groups. The parameters of the von Bertalanffy's growth model were L∞ = 81.1 cm and K = 0.26 per year. The overall sex ratio of males to females was 1: 1.3. The spawning takes place during summer and the size at which 50% of fishes are mature is 42.1 cm for males and 43.3 cm for females. Analysis of the diet...

Autores: Sukkel, ir Wijnand; van Leeuwen Haagsma, ing Wiepie; van der Wel, ing Cees.
Farmers networks are a valuable instrument for research, development and innovation in organic agriculture. The last 15 years networks of pilot farms have been used in the Netherlands to improve farm performance for integrated and organic farming.  For organic agriculture the BIOM network was set up in 1998. Participating farmers improved their farm performance amongst others by a decrease of the hand labour for weed control and a reduction of the nutrient surpluses. The network also functioned as a facility for on-farm research on various topics. Additional effects of the close contacts between par-ticipants were a closer cooperation between farmers and an incentive for innovation

O monitoramento biológico da exposição a agroquímicos constitui-se em uma avaliação que qualifica e/ou quantifica a exposição de um indivíduo ou de uma amostra da população com o uso de amostras biológicas. Para a realização do monitoramento biológico é necessário o conhecimento de um biomarcador. Os agroquímicos em uso atualmente muitas vezes ocasionam sinais e sintomas que podem estar associados à exposição a mais de um princípio ativo. Nesse sentido, é importante estabelecer indicadores biológicos ou biomarcadores relacionados à exposição a esses produtos, indicadores esses mais específicos e baseados em critérios científicos bem estabelecidos.

Autores: Delitti,Welington Braz Carvalho; Meguro,Marico; Pausas,Juli Garcia.
This work aimed to develop allometric equations for tree biomass estimation, and to determine the site biomass in different "cerrado" ecosystems. Destructive sampling in a "campo cerrado" (open savanna) was carried out at the Biological Reserve of Moji-Guaçu, State of São Paulo, southeastern Brazil. This "campo cerrado" (open savanna) grows under a tropical climate and on acid, low nutrient soils. Sixty wood plants were cut to ground level and measurements of diameter, height and weight of leaves and stems were taken. We selected the best equations among the most commonly used mathematical relations according to R² values, significance, and standard error. Both diameter (D) and height (H) showed good relationship with plant biomass, but the use of these...

Provedor de dados: 77
Autores: Saviolo Moreira,Rafael; Alexandre Sgrott,Emerson; Seiji,Fernando; Luiz Smith,Ricardo.
The objective of this paper is to establish, validate and test the reproducibility and accuracy of a digital method to measure linear and angular distances in human hard palate of dry skulls. Digital photographs were made in 10 human adult skulls and measurements were made with the aid of AutoCAD software and with a digital caliper in the same skulls by one observer in a blind fashion to compare both methods. To validate the digital method, measurements was made in 20 skulls by 3 observers. The differences of the measurements were not statistically significant between both method and between the 3 observers. The use of digital cameras followed by image analysis with AutoCAD, a software initially developed for engineering and architecture, revealed to be an...

Autores: Röhrig, Peter; Mäder, Rolf.
Öko-Lebensmittel werden ohne Einsatz von Gentechnik hergestellt. Das erwarten die Verbraucher, es entspricht dem Selbstverständnis der Öko-Unternehmer und es ist gesetzlich vorgeschrieben. Dieser Erwartung nachzukommen, wird für Bio-Unternehmen allerdings immer schwieriger, denn durch den zunehmenden Einsatz von Gentechnik ist an immer mehr Stellen im Herstellungsprozess eine Kontamination möglich. Während sich bisher in erster Linie Importeure und Verarbeiter von Soja, Mais und Raps zu erheblichen Anstregungen genötigt sahen, um ihre Produkte frei von Gentechnik zu halten, werden künftig auch zunehmend mehr Landwirte Vorkehrungen treffen müssen. Für Bauern und Unternehmer gilt es zunächst, ihr Risiko im Hinblick auf Gentechnikeinträge abzuschätzen: Werden...

Bioprospection Beyond Intellectual Property Rights: The Kani Model of Access and Benefit Sharing
Provedor de dados: 31
Autores: Pascual,   Unai; Dedeurwaerdere,   Tom; Krishna,   Vijesh V.
This paper addresses the value of bioprospection for genetic resources (GR) and traditional knowledge (TK) from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from evolutionary institutional economics. Drawing on a unique 'access and benefit sharing' (ABS) bioprospecting contract from the Western Ghats, India, we show how the monetary value of plant genetic information from the traditional knowledge holders' perspective can be assessed using a contingent valuation modelling approach. While the study allows the identification of such values from one of the main stakeholder's (i.e, the Kani community) perspective, it also allows to point out some of the key gaps in the...

Bioreactors in coffee micropropagation
Provedor de dados: 61
Autores: Etienne,Hervé; Dechamp,E; Barry-Etienne,D; Bertrand,Bernóit.
In coffee, bioreactors are the most promising way for scaling-up micropropagation processes, particularly somatic embryogenesis. The availability of an efficient somatic embryogenesis process would allow the rapid mass production of heterozygous materials such as selected Coffea canephora clones and F1 Arabica hybrid varieties. For the last fifteen years, bioreactors (mechanically or pneumatically agitated bioreactors, temporary immersion bioreactors) have mostly been used on coffee to optimize the mass regeneration of somatic embryos from embryogenic tissues. This review presents the main results, obtained with several bioreactor models, concerning the different steps of the micropropagation process : i) the multiplication of embryogenic tissues, ii) the...

Biosorption of heavy metals by Talaromyces helicus: a trained fungus for copper and biphenyl detoxification
Provedor de dados: 69
Autores: Romero,M. Cristina; Reinoso,Enso H.; Urrutia,M. Inés; Moreno Kiernan,Alejandro.
At present, it is common to observe environments with organic and inorganic pollution, defined as co-contamination. Most industrial and urban effluents releases both pollutant types, leading to a complex environmental problem, as the biota must be tolerant to both xenobiotics. T. helicus, an efficient strain to degrade biphenyl, was trained with high copper levels, and became co tolerant to cobalt, lead and cadmium when was cultured in their presence. The copper adaptation was the result of physiological mechanisms, and the activated biochemical processes conferred resistance to Cu2+ as well as to other heavy metals. Furthermore, the Cu2+ adaptation of the mycelium was also transferred to the spores, that removed twice as much copper from solution than...

Autores: Hassan Khani,Mohammad; Reza Keshtkar,Ali; Meysami,Behrouz; Firouz Zarea,Mohammad; Jalali,Reza.
Biosorption of heavy metals can be an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this paper uranium biosorption by protonated, Ca-pretreated and non-pretreated Cystoseira indica algae biomass was investigated in a batch system. The results of the kinetic studies showed that the sorption of uranium on protonated and non-pretreated biomass followed pseudo-second order kinetics. The effect of pH on the equilibrium uranium sorption capacity of Cystoseira indica exhibited that highest uptake occurred at pH 4 at a solution with 350 mg/l uranium concentration. At various initial uranium concentrations from 50 to 1000 mg/l, batch sorption equilibrium at 30&amp;ordm;C was reached within 3 hrs and the sorption...

ABSTRACT: In 2005, there were 90 million hectares cultivated with GMOs by 8.5 million producers in 21 countries. In 2006, we commemorated 10 years of commercial production of GMOs. Currently there are 10 million farmers planting 100 million hectares. However, several points were raised concerning the environmental impact of GMOs: (1) risk of cultivated or wild hybrid become a harmful invasive species, (2) development of resistance by the massive use of technology, (3) possibility of vertical or horizontal gene flow, (4) adverse effect on non-target and beneficial species, (5) impacts on crop production systems. This article discusses the main results on those concerns. The data obtained so far show that the environmental impacts of GMOs ares similar to a...

Biotechnology and Economic Development:  The Economic Benefits of Maize Streak Virus Tolerant Maize in Kenya
Provedor de dados: 31
Autores: Andreu,   Monica Lopez; Peterson,   Hikaru Hanawa; Grunewald,   Orlen C.; Norman,   David W.
For countries that could not benefit from the Green Revolution due to heterogeneous and unfavorable biophysical environments, agricultural biotechnology potentially provides a means of improving the quality and quantity of agricultural production.  This paper analyses some of the major issues relating to the utilization of biotechnology in Kenya.  A partial equilibrium trade model is applied to Kenya's corn market to study the potential of genetically modified maize that is tolerant to the Maize Streak Virus. The model accounts for home production and consumption; the positive results of the welfare estimation are disaggregated between consumers, large and small Kenyan corn farms.

Autores: Varela,Liliana; Bisang,Roberto.
In the 1980s, the technical pattern of production in agriculture changed due to the increasing design of genetically modified plants. Modern biotechnology thrived on events requiring certain thresholds of scientific and technological skills as well as scale economies usually seen in developed countries. The mergers and acquisitions during the mid-1990s led to a world-wide oligopoly composed of very few agri-biotechnological mega-corporations and the literature discusses the impact of the mergers and acquisitions on the agriculture of developing countries with comparative advantages in agriculture. This paper analyzes the world-wide process of agri-biotechnological mega-corporation mergers and acquisitions as well as its impact and interrelationships with...

Biotransformation of 1,8-cineole, the main product of Eucalyptus oils
Provedor de dados: 69
Autores: Rodríguez,Paula; Sierra,Wilson; Rodríguez,Sonia; Menéndez,Pilar.
The forest industry in Uruguay has grown considerably during the last decade. Eucalyptus plantations account for 74% of the forested land, with Eucalyptus globulus being the most widely distributed species. This industry is dedicated exclusively to the production of wood without exploiting the by-products (leaves and small branches). Eucalyptus leaves are known to contain important amounts of essential oils composed primarily of 1,8-cineole (1,3,3-trymethyl-2-oxabicyclo[2.2.2]octane). In this work, the biotransformation of 1,8-cineole, is achieved using a native bacterium (Rhodococcus sp.) which was isolated from the soil of Eucalyptus forest. A 98% of bioconversion was achieved. Three different optically pure compounds were obtained, and they were...

A strain of Absidia fusca was isolated from a pesticide-contaminated soil (Annaba, Algeria). The biotransformation capability of this strain towards two polycyclic aromatic hydrocarbons (PAHs): anthracene and fluoranthene was compared to that exhibited by another strain of A. fusca isolated from a non-contaminated milieu and considered as a control. The results obtained were statistically analyzed and showed that the strain isolated from the contaminated soil was more efficient than the control to remove anthracene from the medium, during all the kinetics (90% removed versus 45% after 24 hrs). Concerning fluoranthene, the amount removed by both strains was very high during the first 24 hrs however the control strain was slightly more efficient (94% versus...

Biting the Bullet : How to Secure Access to Drylands Resources for Multiple Users
Provedor de dados: 31
Autores: Mwangi,   Esther; Dohrn,   Stephan.
Close to one billion people worldwide depend directly upon the drylands for their livelihoods. Because of their climatic conditions and political and economic marginalization drylands also have some of the highest incidents of poverty. Pastoral and sedentary production systems coexist in these areas and both very often use common property arrangements to manage access and use of natural resources. Despite their history of complementary interactions, pastoralists and sedentary farmers are increasingly faced with conflicting claims over land and other natural resources. Past policy interventions and existing regulatory frameworks have not been able to offer lasting solutions to the problems related to land tenure and resource access; problems between the...

Bivalve genomics
Provedor de dados: 5
Autores: Saavedra, Carlos; Bachere, Evelyne.
Interest in bivalve genomics has emerged during the last decade, owing to the importance of these organisms in aquaculture and fisheries and to their role in marine environmental science. Knowledge of bivalve genome structure, function and evolution resulting from 20th century "single gene" approaches is limited, but genomic technologies are called to dramatically increase it. Research based on linkage maps, transcriptomics and proteomics is being carried out to study the genetic and molecular bases of traits of interest in bivalve farming industry, mainly disease susceptibility, tolerance to environmental stress, and growth. The Pacific oyster (Crassostrea gigas) is now the focus of an international genome-sequencing consortium. The use of bivalves in...

For a long time, population geneticists have had to content themselves with analysing neutral markers to infer selection processes indirectly. The recent improvement of sequencing tools now enables them to analyse the variations of a large number of genes and therefore to spot the genes, or the amino acids, which are under the direct influence of the selection (Yang &amp; Bielawski, 2000). In order to analyse the selection processes acting on the mutations and discriminate the different factors acting on their evolution (genetic selection or drift), it is essential to compare polymorphism data between genomes of the same species/population and divergence data between species/populations (Kimura, 1983). Recently, polymorphism data has become available for a...

Black spot diseases in carrot
Provedor de dados: 21
Autores: Voorrips, Roeland E.; Zijlstra, Sierd; Köhl, Jürgen; Kastelein, Pieter.
An important problem in organic carrot production in the Netherlands is the occurrence of black spots during storage. Several different fungal pathogens cause similar symptoms, which are collectively known as black spot diseases. We identified Alternaria radicina, A. dauci and Rhexocercosporidium carotae (syn. Acrothecium carotae) as the most prevalent black spot pathogens. We developed laboratory test methods for resistance to A. radicina and R. carotae, and assessed resistance in a collection of cultivated varieties and more exotic material.

Black vine weevil and other wingless weevils: are there any effective conrol methods applicable in outdoor strawberry in Nordic countries?
Provedor de dados: 21
Autores: Lindqvist, Isa; Tuovinen, Tuomo.
The black vine weevil (Otiorhynchus sulcatus) is a common pest in Central Europe but rather new on outdoor crops in Finland. Spreading of enthomopathogenic nematodes against weevils by drip irrigation was tested at MTT during 2003-2004. The results proved that at least in small-scale use the nematodes were easily spread through the irrigation system into the field. We were not able to prove the efficiency of the nematodes against larvae because of too low level of both species populations in the experimental cages in the field.

blaGES carrying Pseudomonas aeruginosa isolates from a public hospital in Rio de Janeiro, Brazil
Provedor de dados: 55
Autores: Pellegrino,Flávia L. P. C.; Netto-dos Santos,Kátia R.; Riley,Lee W.; Moreira,Beatriz M.
Previous analysis of Pseudomonas aeruginosa class-1 integrons from Rio de Janeiro, Brazil, revealed the blaGES gene in one isolate. We screened isolates of two widespread PFGE genotypes, A and B, at a public hospital in Rio, for the presence of blaGES. The gene was detected in all seven P. aeruginosa isolates belonging to genotype B. Three of the seven genotype-B isolates were resistant to amikacin, aztreonam, ceftazidime, cefepime, ciprofloxacin, gentamicin, imipenem, meropenem, piperacillin-tazobactam and ticarcillin-clavulanic acid. The other four isolates were resistant to all these agents, except gentamicin, imipenem, meropenem and piperacillin-tazobactam. A synergistic effect between ceftazidime and imipenem or clavulanic acid suggested the...

Blastocyst-endometrium interaction: intertwining a cytokine network
Provedor de dados: 56
Autores: Castro-Rendón,W.A.; Castro-Álvarez,J.F.; Guzmán-Martinez,C.; Bueno-Sanchez,J.C.
The successful implantation of the blastocyst depends on adequate interactions between the embryo and the uterus. The development of the embryo begins with the fertilized ovum, a single totipotent cell which undergoes mitosis and gives rise to a multicellular structure named blastocyst. At the same time, increasing concentrations of ovarian steroid hormones initiate a complex signaling cascade that stimulates the differentiation of endometrial stromal cells to decidual cells, preparing the uterus to lodge the embryo. Studies in humans and in other mammals have shown that cytokines and growth factors are produced by the pre-implantation embryo and cells of the reproductive tract; however, the interactions between these factors that converge for successful...

Body fat and cholecalciferol supplementation in elderly homebound individuals
Provedor de dados: 56
Autores: Canto-Costa,M.H.S.; Kunii,I.; Hauache,O.M.
Vitamin D deficiency, observed mainly in the geriatric population, is responsible for loss of bone mass and increased risk of bone fractures. Currently, recommended doses of cholecalciferol are advised, but since there are few studies evaluating the factors that influence the serum levels of 25-hydroxyvitamin D (25(OH)D) following supplementation, we analyzed the relationship between the increase in serum 25(OH)D after supplementation and body fat. We studied a group of 42 homebound elderly subjects over 65 years old (31 women) in order to assess whether there is a need for adjustment of the doses of cholecalciferol administered to this group according to their adipose mass. Baseline measurements of 25(OH)D, intact parathyroid hormone and bone remodeling...

We report new data on the intersexual and geographical variation in body mass of the Geoffroy's cat (Oncifelis geoffroyi d'Orbigny and Gervais 1844), a little known small cat from South America, and combine them with the existing information to compare alternative hypotheses for variation in body mass. Most data on the body mass of O. geoffroyi have been obtained from previous research on this felid in four study areas of southern Brazil and central and southern Argentina. These data were added to those reported for other three additional locations. Our results set the body mass of O. geoffroyi to 4.26 ± 1.03 kg (mean ± SD, n = 56). We also show that males generally are heavier than females throughout most of this species' distributional range. Body mass...

Bofedales: high altitude peatlands of the central Andes
Provedor de dados: 97
Autores: SQUEO,FRANCISCO A; WARNER,BARRY G; ARAVENA,RAMÓN; ESPINOZA,DIANA.
There is an exceptional group of alpine peatlands in the world situated in the arid grasslands of the central Andes. The peatlands in northern Chile occur in the most arid part of their range. Members of the Juncaceae are the primary peat-forming plant species. Fresh and mildly saline groundwaters originate from glaciers, snowmelt and rain are the water sources for the northern Chile peatlands. Paleoecological investigations suggest that some peatlands are recent features of the landscape having developed within the last three thousand years or less. These peatlands are unique, extremely fragile water features sensitive to climate changes and human disturbances such as regional mining activity. Much more work is required to develop scientifically based...

Bonamia ostreae and Ostrea edulis : a stable host-parasite system in France?
Provedor de dados: 5
Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Francois, Cyrille; Joly, Jean-pierre.
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. After its first description in June 1979 in L'Ile Tudy, Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs. Bonamiosis and marteiliosis, another protozoan disease appeared in the seventies, drastically reduced the French flat oyster production from 20 000 tonnes in 1970 to less than 2000 tonnes after 1981. In 2001, about 1650 t of flat oysters were marketed in France. The production is restricted to several areas specialised in reproduction, growth and/or marketing, and depends on transfers of animals. Most important production...

Autores: Oliveira,Rafael Carvalho de; Costa,Luciano da Fontoura; Fernandes,Evandro Abreu; Alvarenga,Bauer Oliveira e; Matioli,Sérgio Russo; Beletti,Marcelo Emílio.
The objective of this work was to identify alterations in the histomorphology of the cortical bone tissue of broilers submitted to growing and finisher rations formulated with five different sources of phosphorus: dicalcium phosphate, simple superphosphate, triple superphosphate, monoammonium phosphate and Araxá rock phosphate. Histological images had their components segmented, and were called regions of interest (ROI). Images were analyzed through developed algorithms, using the SCILAB mathematical environment. Eleven features were considered in order to obtain a complete description of the bone images: percentage of bone by area, ROI area, ROI perimeters, ROI elongation, ROI angle and their respective standard deviations, besides entropy of ROI angles...

Boomvormig vertakte haarmossen in Nederland: een (her)ontdekking die vooral vragen oproept
Provedor de dados: 16
Autores: Kruijer, Hans J.D.; Buter, Chris; Hesse, Cris; Zanten, Ben O. van.
Sinds 2000 zijn in Nederland 9 populaties van Polytrichum commune Hedw. s.l. ontdekt waarin planten voorkomen waarvan de rechtopstaande stengels opvallend sterk, en vaak boomvormig, vertakt zijn. De planten van het Mastbosch (Noord-Brabant) behoren tot P. commune s. str., die van de andere populaties tot P. perigoniale Michx. Vanwege de ingewikkelde systematiek van het P. commune-complex en de hierdoor onstane onduidelijkheden omtrent de identiteit van de soorten in dit complex, is het nodig om in artikelen en rapporten waarin dit complex of zijn soorten worden behandeld, altijd een referentie te geven naar de gebruikte determinatiewerken. Voor dit artikel is het materiaal op naam gebracht met behulp van Schoepe’s bewerking van de Polytrichaceae.10 De 9...

Bounded Rationality and Repeated Network Formation
Provedor de dados: 31
Autores: Beal,   Sylvain; Querou,   Nicolas.
We define a finite-horizon repeated network formation game with consent, and study the differences induced by different levels of individual rationality. We prove that perfectly rational players will remain unconnected at the equilibrium, while nonempty equilibrium networks may form when, following Neyman (1985), players are assumed to behave as finite automata. We define two types of equilibria, namely the Repeated Nash Network (RNN), in which the same network forms at each period, and the Repeated Nash Equilibrium (RNE), in which different networks may form. We state a sufficient condition under which a given network may be implemented as a RNN. Then, we provide structural properties of RNE. For instance, players may form totally different networks at...

Bovine respiratory syncytial virus: immunohistochemichal detection in mouse and bovine tissues using a Mab against human respiratory syncytial virus
Provedor de dados: 45
Autores: Almeida,R.S.; Spilki,F.R.; Roehe,P.M.; Verinaud,L.M.C.; Arns,C.W.
An immunoistochemical (IHC) test was developed to detect bovine respiratory syncytial virus (BRSV) in cell cultures and tissues of experimentally infected mice and calves, using a commercial monoclonal antibody (Mab) against human respiratory syncytial virus (HRSV), as a less expensive alternative, instead of producing specific monoclonal antibodies to BRSV. Clinical samples from calves suffering respiratory disease were also submitted to this test. IHC detected BRSV antigens in mouse tracheas (3, 5 and 7 days post-infection) and lungs (5 and 7 days post-infection), and in one of three lungs from experimentally infected calves. Lungs samples from two naturally infected calves were tested and resulted positive for BRSV by the IHC test. These results suggest...

BpuAmI: a novel SacI neoschizomer from Bacillus pumilus discovered in an isolate from Amazon Basin, recognizing 5'-GAG¯CTC-3'
Provedor de dados: 58
Autores: Chies,Jocelei M.; Dias,Ana C. de O.; Maia,Hélio M.M.; Astolfi-Filho,Spartaco.
A strain of Bacillus pumilus was isolated and identified from water samples collected from a small affluent of the Amazon River. Type II restriction endonuclease activity was detected in these bacteria. The enzyme was purified and the molecular weight of the native protein estimated by gel filtration and SDS-PAGE. The optimum pH, temperature and salt requirements were determined. Quality control assays showed the complete absence of "nonspecific nucleases." Restriction cleavage analysis and DNA sequencing of restriction fragments allowed the unequivocal demonstration of 5´GAG&lt;FONT FACE=Symbol&gt;¯&lt;/FONT&gt;CTC3´ as the recognition sequence. This enzyme was named BpuAmI and is apparently a neoschizomer of the prototype restriction endonuclease SacI....

Brachidontes variabilis and Patella sp as quantitative biological indicators for cadmium, lead and mercury in the Lebanese coastal waters
Provedor de dados: 5
Autores: Nakhle, Khaled; Cossa, Daniel; Khalaf, Ghaby; Beliaeff, Benoit.
The mussel, Brachidontes variabilis, and the limpet, Patella sp., were used as indicators to monitor cadmium, lead and mercury concentrations along the Lebanese coast. Studies were carried out in order to define the best strategy for assessing and minimizing the effects of size and physiological condition on the metal contents of the molluscs, and corrective models were constructed. Metal concentrations in surface water were measured to estimate bioconcentration factors (BCFs). The BCFs varied from 8.3 x 10(3) to 3.4 x 10(4), from 7.5 x 10(3) to 8.0 X 10(3) and from 3.0 x 10(4) to 3.2 x 10(4), for Cd, Pb and Hg, respectively. For limpets, BCFs varied from 1.7 x 10(4) to 7.4 x 10(4) for Cd, from 2.5 x 10(3) to 6 x 103 for Pb and remained fairly constant at...

A tabular review of the Lower Carboniferous (Mississippian) brachiopods from Germany is given combined with data on their stratigraphic and palaeogeographic distribution. A complete revision proved impossible since too many groups are in need of an extensive reassessment, and many species are poorly known due to their inadequate preservation. Many species are accompanied by comments on their taxonomic status as an explanation of the current state of knowledge.

Branding in the red meat sector - A conjoint study from Germany
Provedor de dados: 31
Autores: Lueth,   Maren; Spiller,   Achim; Schramm,   Matthias.
During the last years, low price products (e.g., private label) gain increasing market shares in the German meat market. Compared to other countries the share of branded meat from integrated production chains is very low and most fresh meat is sold unlabelled. This study analyzes the advantages of brands from an information economic perspective and emphasizes branding as an important quality assurance and signaling tool. As brand exte nsions offer the opportunity to introduce brands to new markets at much lower costs we examine the brand transfer from the poultry to the red meat market taking Wiesenhof, the German brand leader for chicken and poultry, as an example. We use conjoint and cluster analysis to calculate willingness to pay and market shares for...

Provedor de dados: 26
Autores: Neves, M.F.; Scare, R.F.
Brazil is rapidly becoming a major player in the world beef market. The Brascan Company is trying to capture more value in the beef business in order to enhance its investments. Opportunities are available for extending agro-food chains and networks that could contribute to this development. Two major strategies are discussed: (1) to become a large and reliable supplier in a beef chain, Brascan needs to grow horizontally; (2) to capture added value, Brascan needs to improve coordination in the vertical direction of the supply chain. The company is currently identifying strategies that could be helpful to achieve these aims.

Coffee is one of the most valuable agricultural commodities and ranks second on international trade exchanges. The genus Coffea belongs to the Rubiaceae family which includes other important plants. The genus contains about 100 species but commercial production is based only on two species, Coffea arabica and Coffea canephora that represent about 70 % and 30 % of the total coffee market, respectively. The Brazilian Coffee Genome Project was designed with the objective of making modern genomics resources available to the coffee scientific community, working on different aspects of the coffee production chain. We have single-pass sequenced a total of 214,964 randomly picked clones from 37 cDNA libraries of C. arabica, C. canephora and C. racemosa,...

Brazilian consumers' perception of tenderness of beef steaks classified by shear force and taste
Provedor de dados: 63
Autores: Delgado,Eduardo Francisquine; Aguiar,Ana Paula; Ortega,Edwin Moisés Marcos; Spoto,Marta Helena Fillet; Castillo,Carmen Josefina Contreras.
The knowledge of consumer perception of meat tenderness and taste is essential to forecast a Brazilian quality value-based beef market. This study aimed to verify perception of tender (WBSF &lt; 4.1 kg) from tough (&gt; 4.8 kg) strip loin steak or uncharacteristic (calcium-treated/Ca-IM) and normal (non-calcium/NO-Ca) meat taste by consumers according to gender, age, education and income levels. Steaks were previously classified by shear force measurements as tender or tough. Each consumer was served a paired sample of one tender and of one tough steak, which were either Ca-IM or NO-Ca treated before tenderness classification. Three hundred and eight consumers answered a nine-point intensity (tenderness) and hedonic (taste) scales evaluation questionnaire....

Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature
Provedor de dados: 56
Autores: Cunha-Melo,J.R.; Santos,G.C.; Andrade,M.V.
Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and...

Provedor de dados: 31
Autores: Sauer,   Johannes; Graversen,   Jesper T.; Park,   Timothy A.
This paper attempts to quantitatively measure the change in the productivity of Danish organic farming in recent years by using panel data on 56 organic farms mainly engaged in milk production for the period 2002 to 2004.  Based on a translog production frontier framework the technical and scale efficiency on farm level is analyzed by considering also curvature consistency.  The total change in productivity for the reference period is measured by using the Malmquist total factor productivity index approach based on a time trends as well as a general index model specification.  Input specific bias in technical change as well as a general index model specification.  Input specific bias in technical change as well elasticities of input substitution are...

Breeding and Production of Organic seeds, The Rijk Zwaan view
Provedor de dados: 21
Autores: Driessen, Ir. Ronald G.
Rijk Zwaan Seed Company offers organic vegetable seeds to the market. Breeding of varieties especially for the organic market has started, but only on a basic level. More knowledge and a more important market are needed to justify a higher input. In organic seed production many problems are encountered, espe-cially in seed production of biennial crops. Therefore much effort is put on improving the organic seed production of these crops, in cooperation with other companies, universities and institutes. Advanced seed treatments are needed to avoid seed borne pathogens. For further growth of the market for organic vegetable seeds, more knowledge, commit-ment in the whole organic chain and unambiguous regulations are needed.

Breeding in organic farming: different strategies, different demands.
Provedor de dados: 21
Autores: Nauta, Msc. W.J.; Saatkamp, Dr. H.; Baars, Dr. T.; Roep, Dr. D.
Abstract – Due to regulations organic farming is sub-jected to a different regime then conventional farm-ing. This results in different environments for ani-mals. The question is whether one overall breeding goal is sufficient to cover all different demands of organic farmers. A survey among 132 Dutch organic dairy farmers revealed that 55% of the farmers are specialized in milk production and 45% is running a multi-functional farm. The specialized milk production farms were significantly more intensive in farming compared to the multifunctional farms. Farmers from both strategies were also asked to value different breeding aspects of animals. In general farmers val-ued different aspects more or less the same: they wanted a robust, long living cow, with...

Plant breeding systems are considered to reflect species' life history characteristics, selection due to biotic or abiotic factors, pollination conditions, or a combination of these. Reproductive systems may vary over ecological gradients. The breeding system of the ornithophilous Embothrium coccineum (Proteaceae) from temperate South America was studied by pollination treatments: manual self-pollination, manual cross-pollination, automatic self-pollination, and natural pollination. These treatments were conducted in a coastal western and an Andean eastern population. Embothrium coccineum was found to be self-incompatible and highly dependent on the pollinating agent at both sites. However, pollen limitations were greater in the coastal population, as...

Sustainable ecosystem management relies on a diverse and multi-faceted knowledge system in which techniques are continuously updated to reflect current understanding and needs.  The challenge is to minimize delay as ideas flow from intent through scientific capability, and finally to implementation to achieve desired outcomes.  The best way to do this is by setting the stage for the flow of knowledge between researchers, policy makers, and resource managers.  The cultural differences between these groups magnify the challenge.  This paper highlights the importance of the tacit dimension of knowledge, and how this renders the concept of knowledge transfer much less useful than the concepts of information transfer and technology transfer. Instead of...

Bringing Biophysical Models into the Economic Laboratory: An Experimental Analysis of Sediment Trading in Australia
Provedor de dados: 31
Autores: Tisdell,   John G.
Experimental economics has emerged and matured as a formal method for questioning and stress testing economic theory and assumptions concerning individual behavior. More recently, experimental methods have been used successfully in an economic laboratory to test alternative environmental policy options. The data underpinning these experiments is often stylized or hypothetical in nature. Ecologists and experimental economics have much to gain by exploring ways to underpin economic experiments with data generated from biophysical models in terms of external validity and salient features of the issue at hand. The study makes a contribution by demonstrating how underpinning experiments with regionally modeled biophysical data may give insights which would not...

Provedor de dados: 21
Autores: Vittersø, Researcher G.; Hegnes, Researcher A. W.; Jacobsen, Head of Research E.; Torjusen, Researcher H.
The point of departure for this paper is the observation that in spite of the public measures taken in order to increase the use of organic food in the out of home eating sector (the catering sector), there is little evidence that this sector has contributed to an overall increase in consumption of organic food. Our aim with this paper is not to discuss whether this is the case or not, but with an open mind we want to point at some factors or mechanisms that may explain the (lack of) connections between consumption of food within and outside of the home.

We investigate the role of broadband access on the probability of telecommuting and whether individuals who work from home receive greater compensation.  We also assess whether telecommuting differs between more- and less-densely populated areas.  Telecommuting responds positively to local average commuting time and to local access to High-Speed Internet service. Differences in broadband access explain three-fourths of the gap in telecommuting between urban and rural markets.  Telecommuters and other IT users do not earn significantly more than otherwise observationally comparable workers.  Already highly skilled and highly paid workers are the most likely to telecommute and so they do not earn more because they telecommute. As broadband access improves in...

In the latest years more attention has been given to mechanisms for bird adaptation at post-hatching period by management of environmental conditions and formulations of diets offered during this period when digestive, immune, and thermo-regulating systems suffer slight changes. In post-hatching period, digestive system is anatomically complete, but its functionality is still immature in relation to adult birds. The chick immunity depends on maternal antibodies transferred to egg just before laying. In addition, variations within thermal comfort zone might affect initial development of chick. For example, high temperatures may induce hyperthermia with dehydration, while low temperatures may lead to hypothermia responsible by pulmonary hypertension...

In three consecutive spawning seasons, the annual photothermal manipulation was not effective for the maturation and natural spawning of females although males were running. Females were HCG injected, releasing non fertilized eggs. Artificial fertilization was carried out after stripping the fish with a total production of 18,000 fertilized eggs in 2001 (egg diameter=800±10 µm), 55,300 in 2002 (egg diameter= 850±12 µm)and 1,635,000 fertilized eggs in 2003 (egg diameter 818.4 ±30.08 µm, oil drop 98.1 ±2.96 µm). For the study of the ovulationtime,...

Brotação e produção das videiras 'Cabernet Sauvignon' e 'Pinot Noir' submetidas a diferentes concentrações de cianamida hidrogenada
Provedor de dados: 94
Autores: Marodin,Gilmar Arduino Bettio; Guerra,Denis Salvati; Zanini,Claiton Luiz Dvoranovski; Argenta,Fabiano; Grasselli,Vinicius.
A ausência de frio invernal na videira produz efeitos adversos, como o atraso e desuniformidade de brotação das gemas, dificuldades de manejo fitossanitário, produção escalonada e de baixa qualidade. O trabalho foi realizado no município de Garibaldi, na região da Encosta Superior do Nordeste do Estado do Rio Grande do Sul, com 640 metros de altitude, com objetivo de testar concentrações de cianamida hidrogenada de 0; 0,5; 1,0; 1,5; 2,0 e 2,5% nas cultivares viníferas Cabernet Sauvignon e Pinot Noir. Os melhores resultados para brotação de gemas de vara foram de 1,75 e 2,0 % em 'Cabernet Sauvignon' e 'Pinot Noir', respectivamente. Concentrações superiores a 1,5 % ocasionaram uniformidade de brotação, independentemente do ano. A maior produtividade foi...

Bt and Ht Corn versus Conventional Pesticide and Herbicide Use. Do Environmental Impacts Differ?
Provedor de dados: 31
Autores: Nillesen,   Eleonora; Scatasta,   Sara; Wesseler,   Justus.
In this paper we empirically assess and compare the environmental impact of pesticide programs for Bt, Ht (glufosinate) and conventional corn in Europe, employing the Environmental Impact Quotient. We use field trial data from Narbons, France 2004 as well as secondary data. Our results show that management of Bt corn has a lower environmental impact than conventional corn programs. Herbicide treatment of the Ht variety also has a much lower environmental impact than that of the two conventional programs. Our empirical findings support the argument of lower environmental and health impacts with respect to pesticide use when growing Bt and Ht corn. The outcomes are relevant for environmental benefit-cost analysis of Bt and Ht corn.

Buffer zone water repellency: effects of the management practice
Provedor de dados: 21
Autores: Rasa, Kimmo; Räty, Mari; Nikolenko, Olga; Horn, Rainer; Yli-Halla, Markku; Uusi-Kämppä, Jaana; Pietola, Liisa.
Water repellency index R was measured in a heavy clay and a sandy loam, used as arable land or buffer zone (BZ). Further, effect of management practise and ageing of BZs were studied. Water repellency was proved to be a common phenomenon on these soils. Harvesting and grazing increased water repellency as does ageing.Low water repellency is supposed to prevent preferential flows and provide evenly distributed water infiltration pattern through large soil volume, which favours nutrient retention.

Building an Agricultural Research for Development System in Africa
Provedor de dados: 31
Autores: Mbabu,   Adiel N.; Ochieng,   Cosmas M.O.
This paper discusses how impact-oriented agricultural research for development systems in Africa can be better organized and managed. Specifically, the paper puts forth the argument that achieving the development targets set by African leaders and the international community, for example, through the Millennium Development Goals, will be extremely difficult without a satisfactory re-orientation of the organization and management of African research for development systems. Such a re-orientation involves carefully linking the agricultural research agenda with national development priorities; improving coordination, interaction, interlinkages, partnerships, and networks among system agents—that is, agricultural research institutes, extension systems, higher...

Provedor de dados: 31
Autores: Puspa,   Jofi; Kuhl,   Rainer.
This study has aims i.e. (1) to investigate the role of inherent personal knowledge in affecting trust, (2) to investigate whether mavens play a role in improving recipient’s knowledge level and trust. We have conducted a study, which involved a total of 134 students as respondents. Correlation between subjective knowledge and trust achieved a medium level, while objective knowledge related to trust at a very low level. Trust in the low-maven-group is the lowest in comparison with the medium- and high- mavens. This study indicates that there are different results in terms of effects of information provided by three different maven groups.

Building of an immunosensor: How can the composition and structure of the thiol attachment layer affect the immunosensor efficiency?
Provedor de dados: 5
Autores: Briand, Elisabeth; Salmain, Michèle; Henry, Jean-marie; Perrot, Hubert; Compere, Chantal; Pradier, Claire-marie.
Immunosensors, based on the immobilization of a model rabbit antibody on mixed self-assembled monolayers and Protein A as a linking agent on gold transducers, were elaborated and characterized at each step by modulated polarization-infrared spectroscopy (PM-IRRAS) and occasionally by atomic force microscopy (AFM) and quartz crystal microbalance (QCM). By testing two different mixed SAMs comprising 11-mercaptoundecanoic acid (MUA), together with either decanethiol (C9CH3) or mercaptohexanol (C6OH), the role of the chemical composition and structure of the antibody attachment layer upon the sensor performance was demonstrated.

Building partnerships for adding value: the role of agribusiness in developing trade
Provedor de dados: 26
Autores: Schmid, A.
As a major retailer with supermarkets in many parts of the world, Royal Ahold serves millions of consumers each day. These consumers become increasingly demanding, but spend less on food than ever before. Besides safe and high-quality food, consumers increasingly want their food to be responsibly produced. Most expect the retailers to ensure this and only very few are willing to accept higher prices to do so. Retailers therefore, also in developing countries, highly depend on large volumes and low prices. Economies of scale are more important than ever, and the focus is on good and short supply chains. The focus on safe and high-quality food brings retailers to implement worldwide food safety programmes, with a network of preferred suppliers. Retailers...

Human butyrylcholinesterase (BChE; EC 3.1.1.8) is a polymorphic enzyme coded by the BCHE gene (3q26.1-q26.2) while the CHE2 gene (2q33-q35) determines a still not characterized substance that forms a complex with BChE (C5), being the CHE2 C5+ and CHE2 C5- phenotypes detected in electrophoresis. The present study investigated BCHE and CHE2 variability and the BChE activity of Brazilian Guarani Amerindians from the Kaiowá and Ñandeva sub-groups living in several indigenous territories in the Brazilian state of Mato Grosso do Sul. The frequency of the BCHE exon 2 D70G (A) allele was 0.60% ± 0.35% while that of the BCHE exon 2 G390V (F-2) allele, never before screened in Amerindians, was 8.82% ± 1.35%. This is the first time that the BCHE gene exon 4 A539T (K)...

Cadeia produtiva da nêspera na região do alto Tietê: indicadores econômicos da produção e mercado atacadista
Provedor de dados: 94
Autores: Perosa,José Matheus; Vieira,Emerson Morais; Nitzsche,Thomas.
A região do Alto Tietê é responsável por 85% da produção de nêspera do Estado de São Paulo. Atividade rentável, nos últimos anos os produtores verificaram uma queda na sua lucratividade. Este trabalho teve como objetivos sistematizar informações econômicas sobre a cadeia produtiva e analisar a estrutura de mercado. A evolução dos preços da nêspera mostra crescimento até o ano 2000 e posterior queda. O mercado atacadista tem atuado como um "colchão" amortecedor. O maior desafio para os produtores de nêspera se encontra no âmbito organizacional. A estrutura de mercado e os resultados da pesquisa de campo indicam que os produtores do Alto Tietê encontram-se em posição vantajosa para um reposicionamento nesse aspecto, importante para uma participação...

Cadmium content of Finnish linseed and estimated consumer intake
Provedor de dados: 21
Autores: Kymäläinen, Hanna-Riitta; Sjöberg, Anna-Maija.
The aim of this study was to screen the cadmium (Cd) contents of seed and seed crush of Finnish linseed and to evaluate the acceptable daily dose. The Cd content of Finnish linseed is of interest, since some properties of linseed as the content of fatty acids are different in northern growth locations compared with other growing areas. Seed samples (N = 85) were collected from the experimental farm of Helsinki University and from commercial fields in different locations in southern Finland and Ostrobothnia. In addition, 15 samples of linseed crush were examined. The cadmium contents of the linseed samples, determined with atomic absorption spectroscopy, varied between 0.27 and 1.3 mg kg-1 (dry weight) (mean 0.61 mg kg-1). The Cd contents of the crush...

Cadmium pathways in an exploited intertidal ecosystem with chronic cadmium inputs (Marennes-Oleron, Atlantic coast, France)
Provedor de dados: 5
Autores: Pigeot, J; Miramand, P; Guyot, T; Sauriau, Pierre-guy; Fichet, D; Le Moine, Olivier; Huet, V.
The Marennes-Oleron Bay is subject to chronic pollution by cadmium (Cd) from the Gironde watershed. An ecosystem approach was used to study the fate of cadmium in the different biological compartments. The median Cd concentration was 0.4 mu g g(-1) dry weight for the 63 benthic species measured. When combined with the respective biomasses for the different species studied, we estimated that 7 kg of Cd is partitioned into the soft tissues of the benthic species in the bay. The majority of this cadmium was distributed between primary producers, mainly microphytobenthos (40 %), and suspension-feeders, mainly oysters (40 %). All other benthic species measured were associated with negligible masses of Cd. Two trophic levels contained 98 % of the Cd: 3 kg was...

cagA positive Helicobacter pylori in Brazilian children related to chronic gastritis
Provedor de dados: 55

Helicobacter pylori is a spiral-shaped Gram-negative bacterium. It colonizes the gastric mucosa of humans and persists for decades if not treated. Helicobacter pylori infection affects more than half of the world's population and invariably results in chronic gastritis. The cagA gene is present in about 60 to 70% of H. pylori strains; it encodes a high-molecular-weight protein (120 to 140 kDa) and several investigators have noted a correlation between strains that possess cagA and the severity of gastric mucosal inflammation. We examined the relation between cagA status in H. pylori strains and chronic gastritis with inflammatory processes in children from Marília, São Paulo, Brazil. One-hundred-twenty-one children were analyzed histopathologically and by...

Provedor de dados: 90
Autores: Souza,Renato Ferreira de; Faquin,Valdemar; Torres,Paulo Rogério Ferreira; Baliza,Danielle Pereira.
A calagem e a adubação orgânica podem reduzir a adsorção/precipitação de P no solo, aumentando sua disponibilidade para a absorção vegetal. Visando avaliar o efeito da calagem e do esterco bovino sobre a adsorção de fósforo no solo, foram realizados em casa de vegetação quatro experimentos no delineamento inteiramente ao acaso, em esquema fatorial 4 x 5, com quatro repetições. Os tratamentos foram constituídos por quatro doses de calcário (0; 0,5; 1 e 2 vezes a dose recomendada para atingir V = 60 %) e cinco doses de esterco bovino (0; 2,5; 5,0; 7,5 e 10 % do volume total de solo), aplicados em amostras de 4 dm³ de Neossolo Quartzarênico órtico (RQo), Latossolo Vermelho-Amarelo distrófico textura média (LVAd-1), Latossolo Vermelho-Amarelo distrófico...

Calagem superficial e cobertura de aveia preta antecedendo os cultivos de milho e soja em sistema plantio direto
Provedor de dados: 90
Autores: Caires,Eduardo Fávero; Garbuio,Fernando José; Alleoni,Luís Reynaldo Ferracciú; Cambri,Michel Alexandro.
Os resíduos de plantas de cobertura podem mobilizar cátions no solo e beneficiar a ação da calagem superficial, por meio da liberação de ácidos orgânicos de baixo peso molecular da fração solúvel dos resíduos. Entretanto, faltam estudos no campo que comprovem tais efeitos em sistema plantio direto. Para avaliar as alterações químicas do solo e a resposta do milho e da soja com a aplicação de doses de calcário dolomítico na superfície (0,0, 2,5, 5,0 e 7,5 t ha-1), na ausência e na presença de cobertura de aveia preta, foi realizado um experimento em um Latossolo Vermelho distrófico textura argilo-arenosa, há cinco anos no sistema plantio direto, em Ponta Grossa (PR). As doses de calcário foram aplicadas nas parcelas em novembro de 2000 e, nas subparcelas,...

Calculation of uncertainties in influence quantities in biological essays
Provedor de dados: 52
Autores: Morel,Pierre; Arruda,Tatiana Langbeck de; Bohrer-Morel,Maria Beatriz C.
Due to the need of showing the reliability of results from biological essays, such as in health and environmental areas, laboratories have been implementing quality systems, particularly ABNT NBR ISO/IEC 17025 (ABNT, 2001), which include as one of the requirements, the calculation of uncertainty in essays results. It is of common knowledge that estimating uncertainty in essays using organisms, such as animal and vegetal species, is difficult, preventing from meeting that requirement in the standard. The paper shows the calculation of uncertainties in influences quantities in these essays as a tool to allow validating the measuring process, by using the essays performed by Rhodia Environmental Impact Analysis Laboratory and IPEN Ecotoxicology Laboratory as...

Calibração da Reflectometria no Domínio do Tempo (TDR) para a estimativa da concentração da solução no solo
Provedor de dados: 70
Autores: Souza,Claudinei F.; Folegatti,Marcos V.; Matsura,Edson E.; Or,Dani.
A Reflectometria no Domínio do Tempo (TDR) é um método confiável para medidas in situ da umidade e da concentração da solução no mesmo volume de solo. Entretanto, a interpretação precisa da medida de condutividade elétrica do solo (e umidade do solo) pode requerer uma curva de calibração específica. O objetivo principal deste ensaio foi estabelecer um procedimento de calibração para usar a TDR no cálculo de concentrações de nitrato de potássio (KNO3) em solução do solo. Uma equação que relaciona a condutividade elétrica medida pela TDR e a concentração de KNO3 foram encontradas viabilizando o uso da técnica da TDR na estimativa da umidade e da concentração da solução do solo para o manejo eficiente da fertirrigação.

The anthropogenic affectation was evaluated on the coast N of the Gulf of Batabanó in May 2003 (corresponding to the provinces of Matanzas and Havana), in areas located in the line of the coast. The results were compared with the historical information of the sector. In the coast N and the Ensenada of the Broa, the parameters oxygen saturation, DBO5 and DQO showed characteristic high values of eutrofication. The biggest contribution in the Cianoficies was in the near coastal areas to sources of organic contamination. In the case of the nutrients they show specific data of mesothrofic waters with tendency to the eutrofization and the silts presented a high affectation for toxic metals. The area near to Guanímar is distinguished to present conditions of...

Cambiando de perspectiva: cautivos en el interior de la frontera
Provedor de dados: 125
Autores: Aguirre,Susana.
Este trabajo hace foco en los cautivos indios, personajes ignorados por la historia oficial, que también fueron víctimas acalladas, fruto de la ambivalente relación -pacífica y violenta- entre el mundo indígena y español. Se pone énfasis en la política oficial seguida a partir de su cautiverio, atendiendo de manera especial al reparto, a la modalidad de los depósitos, distinguiéndose aquellos emanados a partir de otras causales.

Cambios bioquímicos post-mortem en músculos de diferentes especies pesqueras. Determinación de la vida útil de las mismas en frío
Provedor de dados: 20
Autores: Massa, A.E.
Se investigaron los cambios bioquímicos post-mortem y se determinó la vida útil comercial de tres especies pesqueras, muy valoradas por el sector industrial pesquero de nuestro país, durante el almacenamiento en frío: lenguado (Paralichthys patagonicus), corvina rubia (Micropogonias furnieri) y la vieira patagónica (Zygochlamis patagónica). Los cambios bioquímicos relacionados con el ATP y sus productos de degradación, la actividad de las principales enzimas involucradas en el catabolismo del ATP y el pH fueron investigados. En base a los contenidos de los compuestos relacionados con la degradación del ATP se establecieron distintos índices químicos para evaluar la frescura y/o la calidad de estos productos. Por otro lado, se monitorearon los niveles de...

Campagne d'évaluation du stock de palourdes du bassin d'Arcachon - Année 2006
Provedor de dados: 5
Autores: Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles.
Between 1980 and 1986, some Arcachon oyster farmers took up breeding the Japanese clam on the foreshore (Robert et Deltreil, 1990). This production was short lived. The steep fall in prices due to economic competition from Spain, Portugal, Italy and Tunisia, predator action such as the trigger fish (Popovsky et al., 1999), added to the significant amount of mortality that occurred in the summer and autumn of 1992 that affected two-thirds of the total stock, led to clam farming being abandoned at the end of the 1980s.  In the Arcachon basin, the Japanese clam (Ruditapes philippinarum) population, now natural to the area, has found favourable conditions for development and is expanding rapidly there. This species has been supplanting the local species...

Campos nativos e matas adjacentes da região de Humaitá (AM): atributos diferenciais dos solos
Provedor de dados: 64
Autores: Martins,Gilvan Coimbra; Ferreira,Mozart Martins; Curi,Nilton; Vitorino,Antonio Carlos Tadeu; Silva,Marx Leandro Naves.
Existem no sul do Amazonas aproximadamente 560 mil hectares de campos de cerrados, distribuídos principalmente, nos municípios de Humaitá, Lábrea e Canutama. A região não é coberta por campos contínuos, mas por várias unidades isoladas entremeadas por matas. As formas de vegetação primitiva indicam ambientes peculiares, como o regime hídrico, fertilidade natural e aeração do solo. Assim, objetivou-se no presente trabalho estabelecer algumas razões da estratificação ambiental entre mata e campo nativo na região de Humaitá (AM). Para tanto, foram observados morfologicamente e amostrados 10 perfis de solos, sendo 5 perfis sob mata e 5 perfis sob campo cerrado nativo. As amostras foram coletadas nas profundidades de 0-20, 20-40 e 60-80 cm, em trincheiras. Os...

Campylobacter sp in eggs from cloacal swab positive breeder hens
Provedor de dados: 58
Autores: Fonseca,Belchiolina Beatriz; Soncini,Ricardo Alfredo; Gimarães,Adelia Rodrigues; Rossi,Daise Aparecida.
Campylobacter sp is a microaerophilic, thermotolerating Gram negative bacterium, known to be one of the main causes of food-borne human infections. Among the foods that carry these microorganisms, the chicken is outstanding. In Brazil, a large chicken exporting country, few researches are conducted about their prevalence in breeder hens and the transmission through eggs. The aim of this research was to verify the presence of Campylobacter sp in the shells and within the eggs from positive cloacal swab breeder hens. Microbiological analyses were made on cloacal swabs of 140 weighed breeder hens. The positive breeder hens were set aside and in a total of 244 of their eggs, Campylobacter sp was present in macerated shells and yolk contents during 7 weeks. Out...

Campylobacter sp in organs and meconium of day-old broiler chicks derived from naturally infected breeder hens
Provedor de dados: 89
Autores: Fonseca,BB; Soncini,RA; Vieira,FL; Siqueira,MS; Guimarães,AR; Beletti,ME; Rossi,DA.
Campylobacter sp is an important agent that causes foodborne infection, particularly in food of poultry origin. Therefore, the efficient control of the transmission routes in chicken farms is of outmost importance to prevent it from spreading. In chicken farms, the main transmission route of this microorganism is horizontal, as the vertical route continues to be the object of inconclusive researches. The objective of this study was to verify the presence of Campylobacter sp in breeder hens, meconium, and other organs of day-old chicks derived from these breeders in order to obtain information on vertical transmission. Microbiological analyses were performed, using cloacal swabs from 279 breeder hens. Positive breeders were segregated, and the presence of...

Can Climate Change Save Lives? A comment on “Economy-wide estimates of the implications of climate change: Human health"
Provedor de dados: 31
Autores: Ackerman,   Frank; Stanton,   Elizabeth A.
In a recent article in this journal, Francesco Bosello, Roberto Roson, and Richard Tol make the surprising prediction that the first stages of global warming will, on balance, save a large number of lives. Bosello et al. fail to substantiate this remarkable estimate, and they make multiple mistaken or misleading assumptions. They rely on research that identifies a simple empirical relationship between temperature and mortality, but ignores the countervailing effect of human adaptation to gradual changes in average temperature. While focusing on small changes in average temperatures, they ignore the important health impacts of extreme weather events such as heat waves, droughts, floods, and hurricanes. They extrapolate this pattern far beyond the level that...

Can Cocoa Farmer Organizations Countervail Buyer Market Power?
Provedor de dados: 31
Autores: Wilcox,   Michael D.; Abbott,   Philip C.
Structural adjustment in less developed countries has often mandated removal of state-run marketing boards to enhance efficiency in the marketing chain and to raise farm income. Concerns have been mounting about the negative side effects of cocoa market liberalization, including replacement of the parastatal by imperfectly competitive marketing institutions and the loss of public goods (e.g. research and extension). It is believed that the link of the supply chain closest to the farmgate may be the least competitive, as farmers in remote areas lack good market information and encounter relatively few buying agents. These concerns, especially related to domestic market competitiveness, have prompted governments, foreign donors and NGOs to promote farmer...

Can Entrepreneurship Be Taught?
Provedor de dados: 31
Autores: Klein,   Peter G.; Bullock,   J. Bruce.
Is entrepreneurship an innate ability or an acquired skill?  Can entrepreneurship acumen be achieved and enhanced through education and training, or are certain people “born” to be entrepreneurs or to act entrepreneurially?  Economists and management theorists give widely divergent answers to these questions.  This paper reviews the major approaches to teaching entrepreneurship, primarily at the undergraduate level, and relates them to economic theories of entrepreneurship.  Surprisingly, we find little connection between the leading approaches to entrepreneurship education and economists’ understanding of the entrepreneurial function.  We assess likely explanations for the lack of contact between these two groups of scholars and suggest possible...

Can genetic engineering for the poor pay off? An ex-ante evaluation of Golden Rice in India
Provedor de dados: 31
Autores: Stein,   Alexander J.; Sachdev,   H.P.S.; Qaim,   Matin.
Genetic engineering (GE) in agriculture is a controversial topic in science and society at large. While some oppose genetically modified crops as proxy of an agricultural system they consider unsustainable and inequitable, the question remains whether GE can benefit the poor within the existing system and what needs to be done to deliver these benefits? Golden Rice has been genetically engineered to produce provitamin A. The technology is still in the testing phase, but, once released, it is expected to address one consequence of poverty " vitamin A deficiency (VAD) " and its health implications. Current interventions to combat VAD rely mainly on pharmaceutical supplementation, which is costly in the long run and only partially successful.  We develop a...

Can Growth Compensate Inequality and Risk?---a welfare analysis for Chinese households
Provedor de dados: 31
Autores: Cao,   Heping; Ligon,   Ethan; Meng,   Xiangyi.
It has been widely observed that China’'s break-neck growth has not been equally shared between rural and urban areas, with urban households' enjoying a much larger proportion. To further test whether regional inequality exists within urban areas, we measure urban households’ vulnerability in a risky environment and decompose this measure to quantify China aggregate risks, province-level risks and idiosyncratic risks faced by households situated in 31 provinces. Besides, under this framework of analysis, we are able to make welfare comparisons between growth, inequality and different risks. We find that inequality has very big negative effect on households'’ welfare, while growth is able to compensate nearly half of it; households seem to be able to smooth...

Can higher legume diversity reduce clover soil fatigue?
Provedor de dados: 21
Autores: Søegaard, Karen; Møller, Kaare.
White clover soil fatigue is an increasing problem in Danish organic dairy farms. The clover cyst nematode (Heterodera trifolii) has been found to play a major role in the problem. Grassland legume species less readily attacked by H. trifolii and less favourable for its reproduction than white clover may offer possibilities for relieving the soil fatigue.    In 2005, screenings were made of nine grass-land legume species / varieties in a field with a rather high level of H. trifolii infestation, pre-cropped with grass/white clover, and in a field with a low infesta-tion level, pre-cropped with maize.    The species grouped in two: 1) White, red, alsike and kura clovers and lucerne had medium to high percentages of nematode attacks and numbers of nematodes...

Can organic farming deliver natural heritage goals in the UK uplands?
Provedor de dados: 21
Autores: Watson, C A; Chamberlain, D E; Norton, L R; Fuller, R J; Atkinson, C J; Fowler, S M; McCracken, D I; Wolfe, M S; Walker, R L.
Policy support for organic farming in the UK is based in part on the ability of organic farming systems to deliver natural heritage benefi ts. Most UK research on the natural heritage benefi ts of organic farming has addressed lowland arable systems. A reanalysis of a subset of data from a MAFF-funded study of biodiversity in England and Wales suggests that organic systems in predominantly pastoral landscapes may show similar biodiversity benefi ts to ones in predominantly arable landscapes. Future research needs to address organically managed pastoral, hill and upland systems across the UK.

Can R&amp;D-Inducing Green Tariffs Replace International Environmental Regulations?
Provedor de dados: 31
Autores: Naghavi,   Alireza.
This paper investigates the link between trade and environment by exploring the effects of green tariffs on the location of firms, innovation and the environment. It shows that tariffs levied on polluting goods could result in less global pollution than harmonization of environmental standards by inducing more pollution abatement R&amp;D, generating lower unit emissions from production, and reducing competition. Green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) strategically inducing abatement R&amp;D by the Northern firm by granting the latter a higher market share, (3) creating abatement R&amp;D by deterring delocation.

Can Resilience be Reconciled with Globalization and the Increasingly Complex Conditions of Resource Degradation in Asian Coastal Regions?
Provedor de dados: 7
Autores: Armitage, Derek; Wilfrid Laurier University; darmitag@wlu.ca; Johnson, Derek; Centre for Maritime Research; dsjohnson@marecentre.nl.
This paper explores the relationship between resilience and globalization. We are concerned, most importantly, with whether resilience is a suitable conceptual framework for natural resource management in the context of the rapid changes and disruptions that globalization causes in social-ecological systems. Although theoretical in scope, we ground this analysis using our experiences in two Asian coastal areas: Junagadh District in Gujarat State, India and Banawa Selatan, in Central Sulawesi, Indonesia. We present the histories of resource exploitation in the two areas, and we attempt to combine a resilience perspective with close attention to the impact of globalization. Our efforts serve as a basis from which to examine the conceptual and practical...

Autores: Lipton,   Michael.
The paper reviews the role of small farms in development and poverty reduction in countries (or regions within a country) with persistent mass poverty. It discusses the arguments supporting the importance of agricultural development for poverty and argues that initial success in reduction of mass poverty requires prior agricultural developments. It explores in particular the role of smallscale farming and policy requirements to ensure the competitive advantage of small farms.

Can the U.S. Ethanol Industry Compete in the Alternative Fuels' Market?
Provedor de dados: 31
Autores: Zhang,   Zibin; Vedenov,   Dmitry V.; Wetzstein,   Michael E.
The U.S. ethanol fuel industry has experienced preferential treatment from federal and state governments ever since the Energy Tax Act of 1978 exempted 10% ethanol/gasoline blend (gasohol) from the federal excise tax.  Combined with a 54¢/gal ethanol import tariff, this exemption was designed to provide incentives for the establishment and development of a U.S. ethanol industry.  Despite these tax exemptions, until recently, the U.S. ethanol fuel industry was unable to expand from a limited regional market.  Ethanol was dominated in the market by MTBE (methyl-tertiary-butyl ether).  Only after MTBE was found to contaminate groundwater and consequently banned in many states did the demand for ethanol expand nationally.  Limit pricing on the part of MTBE...

When Canada ratified the Kyoto Protocol in December 2002, the country committed to decrease its Greenhouse Gas (GHG) emissions by 6% below its 1990 level. It is estimated that this commitment will require Canada to decrease emissions by 270 megatonnes (Mt) per year during the first commitment period 2008 to 2012. Carbon emission trading institutions have been identified, both internationally and domestically, as being a cost effective mechanism for supplying carbon emission reductions. The paper investigates two alternative mechanisms that can be used to allocate carbon and the potential development of the carbon offset credit market. The offset market could be important for the agriculture and forestry sectors, since these sectors have the potential to...

Provedor de dados: 31
Autores: Rude,   James; Meilke,   Karl D.
The WTO Framework Agreement that negotiators accepted in July 2004, and built upon at the 2005 Hong Kong Ministerial meeting provides a guide to the commitments a Doha Development Agenda agreement may contain. These commitments will relate to direct and indirect export subsidies, domestic support and market access. Commitments in each of these areas will have implications for Canadian agriculture. This article explores these implications for supply management, the Canadian Wheat Board and domestic support programs.

Canadian Consumers' Preferences for Food Safety and Agricultural Environment Safety
Provedor de dados: 31
Autores: Veeman,   Michele M.; Li,   Yu.
This project applies statistical models to analyse the relative importance ratings for selected food risk issues given in January 2003 by a representative cross-Canada sample of consumers. Ratings for environmental risks that may be associated with agriculture are also assessed. Results of ordered probit econometric models that analyze the influence of respondent's socio-economic and demographic characteristics on food and environmental risk ratings indicate that these are influenced by gender, age, income, employment and location of residence. Males tended to choose lower risk ratings; residents of Quebec tended to give higher risk ratings to most of the queried food and environmental safety issues. The results suggest that measures of trust in...

Autores: Melo,Nadja Rodrigues de; Taguchi,Hideaki; Culhari,Vitoria V.P.; Sano,Ayako; Fukushima,Kazutaka; Miyaji,Makoto; Manning,Nigel; Kelly,Steven L.; Vilela,Marluce S.
This study investigated the prevalence of C. dubliniensis in a Brazilian family with an HIV - infected child. A total of 42 oral isolates were obtained from eight family members. The identification of C. dubliniensis was performed by polymerase chain reactions (PCR) using primers against a specific sequence of the C. dubliniensis cytochrome b gene. Only the HIV-infected child and his grandmother were colonized by C. dubliniensis. In this study C. dubliniensis isolated from the HIV-infected child exhibited high susceptibility for azoles tested with MICs of 0.125 and 0.5 µg/mL for voriconazole and fluconazole, respectively. Accumulation of [³H] fluconazole in C. dubliniensis isolated from the HIV-infected child was slightly reduced in comparison to the...

Autores: Xavier,S.C.; Chiarelli,I.M.; Lima,W.G.; Gonçalves,R.; Tafuri,W.L.
A remarkable histopathological picture of one asymptomatic dog naturally infected with Leishmania infantum (syn. chagasi) has been presented. Intracellular parasites were ease found in macrophages of all exanimated organs, especially in skin. Embedded paraffin tissues of liver, spleen, axillary and popliteal lymph nodes, and skin (ear, muzzle and abdomen) were stained by hematoxylin and eosin and by immunocytochemical reaction (streptoavidin-peroxidase method) to detect parasites. All organs showed an intense parasitism associated to severe pathological changes. All lymph nodes had conspicuous histological architecture alterations. Lymphocytes were replaced by macrophages stuffed with an intense number of amastigotes forms of Leishmania. The lymphoid...

Cannabidiol, a Cannabis sativa constituent, as an antipsychotic drug
Provedor de dados: 56
Autores: Zuardi,A.W.; Crippa,J.A.S.; Hallak,J.E.C.; Moreira,F.A.; Guimarães,F.S.
A high dose of delta9-tetrahydrocannabinol, the main Cannabis sativa (cannabis) component, induces anxiety and psychotic-like symptoms in healthy volunteers. These effects of delta9-tetrahydrocannabinol are significantly reduced by cannabidiol (CBD), a cannabis constituent which is devoid of the typical effects of the plant. This observation led us to suspect that CBD could have anxiolytic and/or antipsychotic actions. Studies in animal models and in healthy volunteers clearly suggest an anxiolytic-like effect of CBD. The antipsychotic-like properties of CBD have been investigated in animal models using behavioral and neurochemical techniques which suggested that CBD has a pharmacological profile similar to that of atypical antipsychotic drugs. The results...

Canopy gap colonization in the Atlantic Montane Rain Forest
Provedor de dados: 52
Autores: Lima,Renato A. Ferreira de; Moura,Leila Cunha de.
In the Atlantic Montane Rain Forest of South-eastern Brazil, a study was carried out to describe and evaluate canopy gap colonization. Gap composition by herb species was assessed through their soil coverage and woody species by measuring and identifying all individuals taller than one meter. Gap structure (gap size, number and diameter of treefalls), topographic position and surrounding vegetation were also measured. Two genera of Marantaceae were markedly frequent and abundant inside gaps. The more abundant and frequent woody species were shade tolerant. Species-rich families found inside gaps did not differ from the forest as a whole. Results revealed that direct and indirect influences of topography were important to determine gap composition of woody...

CAP Direct Payments and Distributional Conflicts Over Rented Land within Corporate Farms in the New Member States
Provedor de dados: 31
Autores: Latruffe,   Laure; Davidova,   Sophia.
This paper aims to investigate whether distributional issues within corporate farms in the New Member States will be exacerbated by the introduction of the CAP direct payments. The paper focuses on the specific impact of the payments on the land rented to the corporate farms by private landowners. If the latter are not satisfied with the level of rent they receive, they have the option to end their rental contract and withdraw their land from the farm. Before the accession to the EU the landowners did not have strong incentives to withdraw, as the other available opportunities were not associated with higher returns on land ownership. However, this situation might change as the landowners can now cash the direct payments themselves, providing they keep...

CAP Reforms and Total Factor Productivity Growth in Belgian Agriculture: A Malmquist Index Approach
Provedor de dados: 31
Autores: Coelli,   Tim J.; Perelman,   Sergio; Van Lierde,   Dirk.
Have the 1992 and 2000 CAP reforms had any discernable effect upon agricultural productivity? In this study we derive detailed information on the total factor productivity (TFP) growth of arable farms in Belgium over a 16-year period from 1987 to 2002. Calculations are based on a carefully constructed high-quality detailed farm-level data set containing 1728 observations, involving over 100 farms in most years. Three output variables (cereals, other crops, other outputs) and four input variables (land, labour, capital and other inputs) are constructed, using multilateral Fisher index numbers where crop aggregation is required. The TFP measures are calculated using a Malmquist TFP index relative to a series of data envelopment analysis (DEA) frontiers....

Family-based agriculture plays an important socio-economical role in Brazilian agribusiness. Its development is considered a precondition for an economically efficient and fair society. There are numerous variables influencing the performance of rural business. Several variables can not be controlled by the farmers, but, there are some variables which can be controlled, as farm management. Problems related to farm business sustainability revel inefficiencies in farm management in general, and more specifically in family based agriculture. Therefore the proposal of a rural extension course in management, acts over this deficiency, providing tools for family-based agriculture.

Capacity reduction, quota trading and productivity: the case of a fishery
Provedor de dados: 31
Autores: Fox,   Kevin J.; Grafton,   R. Quentin; Kompas,   Tom; Che,   Tuong Nhu.
We present the first ex post study that quantitatively analyses the effects of a licence buyback and enhanced quota trading on the profitability and productivity of individual vessels in a fishery. Using firm-level data and a profit index decomposition method, we find that small and large vessels and three different trawler fleets all experienced substantial productivity gains in the year immediately following a licence buy-back and the establishment of a quota brokerage service. The apparent ongoing benefits of the buy-back and increased quota trading over the sample period are in stark contrast to the generally unfavourable long-term outcomes commonly associated with vessel buy-backs in input-controlled fisheries.

Capital as a Factor of Production in OECD Agriculture: Measurement and Data
Provedor de dados: 31
Autores: Ball,   V. Eldon; Lindamood,   W.A.; Nehring,   Richard F.; Mesonada,   Carlos San Juan.
This paper provides a farm sector comparison of levels of capital input for fourteen OECD countries for the period 1973-2002. The starting point for construction of a measure of capital input is the measurement of capital stock. Estimates of depreciable capital are derived by representing capital stock at each point of time as a weighted sum of past investments. The weights correspond to the relative efficiencies of capital goods of different ages, so that the weighted components of capital stock have the same efficiency. Estimates of the stock of land are derived from balance sheet data. We convert estimates of capital stock into estimates of capital service flows by means of capital rental prices. Comparisons of levels of capital input among countries...

This paper presents an attempt to model the response of selected farms to decoupled direct payments and the associated impact on the provision of a defined set of non-commodity outputs (NCO’s) using a combined modelling approach consisting of the AgriPoliS and MODAM models. AgriPoliS focuses on the socio-economic dimension of multifunctionality at the individual farm and regional levels and explicitly models heterogeneous farms (in size, location and efficiency) within a competitive and dynamic environment. The linear-programming model MODAM allows a detailed representation of production processes and their impact on the environmental dimension of multifunctionality at the farm level. We simulate the impact of a uniform area payment and a fully decoupled...

Traps lured with semiochemical have been proposed to manage the coffee berry borer, coffee planting is however made under several environmental conditions that may affect the efficacy of traps. Several trap designs and variations were proposed and, therefore, a series of field experiments was carried out to capture coffee berry bores in traps disposed in a low density coffee plantations in the Northern part of the State of Paraná, Brazil. Traps were composed of plastic bottles (2 L) with a window (13 × 18 cm). Ethanol (E), Methanol (M) and coffee oil alone did not improve the capture when transparent traps with a 2 mm hole in the vial dispenser were used; traps lured with E : M mixtures (1:1, 1:2, 1:3) caught similar and higher number of insects than the...

Caractérisation de la virulence d'une souche de Vibrio aestuarianus, pathogène de l'huître Crassostrea gigas
Provedor de dados: 5
Autores: Labreuche, Yannick.
In France. shellfish production is a traditional. well-established industry. mainly based upon commercial farming of the Pacifie oyster. Crassostrea gigas. Since the 1980's, annual mass mortalities of C. gigas have been reported during summer. Several studies on this subject have demonstrated that these mortality outbreaks resulted from complex interactions between the physiologieal andJor genetic status of the oysters. environmental factors, and one or more infectious agents, among which are bacteria of the genus Vibrio.

Caractérisation de marqueurs génétiques fonctionnels de la nutrition et/ou de l'adaptation (les amylases) chez l'huître creuse Crassostrea gigas : intérêts pour la sélection
Provedor de dados: 5
Autores: Prudence, Marie.
Two amylase genes, A and B, from the oyster Crassostrea gigas were characterized. Using PCR-RFLP, 6 and 4 alleles, respectively, were described for the amylase genes A and B. The roles of A and B amylase genes were investigated experimentally. They are expressed during larval and adult stages, and A transcripts are more abundant than B. The A transcript increases significantly with temperature, in high trophic conditions. However, A and B transcript levels do not change when food quantity increases although amylase activity augments. The level of B is correlated with dietary starch quantities, whereas the amount of A appears to remain constant ; simultaneously amylase activity decreases and the KM increases. These results suggest that expression of B is...

Les mortalités d'huîtres observées sur les côtes françaises apparaissent principalement à proximité du sédiment et pendant la gamétogenèse. Les interactions de facteurs environnementaux sur les écosystèmes conchylicoles comme la température, les apports des bassins versants et le compartiment sédimentaire illustrent un risque de mortalité lié à différentes sources de stress (Thème 1). Les variations de la qualité de la ressource trophique pendant l'effort de gamétogenèse favorise une baisse de l'énergie disponible (Thème 2) et contraint l'organisme fragilisé à fournir un effort d'adaptation (Fent 2004). L'apparition d'un stress pendant cette période sensible des huîtres pourrait constituer un facteur aggravant de mortalité. L'objectif de cette étude est...

Caractérisation et dynamique des turbidités en zone côtière : L'exemple de la région marine Bretagne Sud
Provedor de dados: 5
Autores: Tessier, Caroline.
The space and time turbidity variability in Southern Brittany was studied, from the combination of results of hydrological campaigns, long-term instrumented moorings, satellite observations and 3D process-based numerical modelling.  Previous observations exhibit a cross-shore concentration gradient with values hardly exceeding 30 mg/l beyond the littoral zone. Acoustic profilers (ADCP) were moored to measure currents, waves and the associated dynamics of fine particles. Time series of mass concentration in the whole water column were estimated from the analysis of the backscattered signal. During wave episodes, values can reach 100 mg/l at 1.50 m above bottom, just outside the Bay of Vilaine. The empirical calibration of the signal with independent...

A produção de leite de vacas Hereford primíparas e multíparas manejadas sobre campo nativo foi estudada utilizando-se 144 lactações em um período de quatro anos (1995, 1998, 2000, 2001). A estimativa da produção de leite foi realizada em intervalos de 21 dias pela técnica da pesagem antes e após a mamada, do nascimento à desmama (189 dias). Foram considerados os fatores fixos ano, ordem de parto, prenhez, sexo do bezerro e raça do touro. As vacas multíparas produziram mais leite (8,27+0,26) que as primíparas (5,81+0,25 kg dia-1) no pico de lactação (42 dias). A produção total de leite em multíparas também foi superior (158,34+25,51) à das primíparas (915,44+24,47 kg). A produção de leite não foi influenciada pelos demais fatores.

Autores: Alberto Ruiz,Hugo; Arruda Sampaio,Regynaldo; Oliveira,Maurício de; Afonso Ferreira,Paulo.
O objetivo deste trabalho foi avaliar a influência do parcelamento da lâmina de lixiviação sobre as características físicas de solos salino-sódicos. Cilindros foram preenchidos com amostras de solos: NEOSSOLO FLÚVICO (Ae1); NEOSSOLO FLÚVICO, coletado a 0-20 cm (Ae2-s) e 20-50 cm (Ae2-i) de profundidade, e VERTISSOLO (V). O gesso foi incorporado até 15 cm de profundidade, numa quantidade equivalente a 100% da necessidade de gesso para substituição do sódio trocável. O manejo de água consistiu na aplicação de solução de lixiviação com CaCl2 e MgCl2 de uma única vez e do mesmo volume parcelado em duas, quatro e seis vezes, respectivamente, com intervalos de 22 dias entre cada aplicação. Verificou-se que o gesso e a lâmina de lixiviação diminuíram a dispersão...

O objetivo deste trabalho foi caracterizar bioquimicamente duas isolinhas de soja com alto teor de proteína. O aumento do teor de proteína nas isolinhas foi acompanhado por redução no teor de óleo e de carboidratos totais. Em relação à composição aminoacídica, o aumento do teor de proteína promoveu acréscimo em todos os aminoácidos, exceto glicina, alanina, metionina, cisteína e tirosina, mantendo a relação enxofre/nitrogênio. A quantificação dos polipeptídios mostrou que o aumento do teor de proteína manteve inalterado o teor das proteínas 7S, promoveu aumento no teor das proteínas 11S e, conseqüentemente, da relação 11S/7S. Pode haver melhoria na qualidade do farelo de soja das isolinhas, uma vez que as proteínas 11S têm melhor qualidade nutricional do...

ABSTRACT: Domestic cattle breeds are classified in two subspecies: Bos taurus taurus, which have an european origin and Bos taurus indicus, the zebuines, originated in India. The main phenotypic difference between them is the presence of the hump, observed in the zebuines and absent in taurines. In addition, the sexual Y chromosome has been considered as a marker for these subspecies. Animals that have a submetacentric or metacêntrico Y chromosome are considered as Bos taurus taurus and those with acrocentric Y chromosome are typically zebuine animals (Bos taurus indicus). On the other hand it is known that the Y-chromosome possesses genes related to spermatogenesis and consequently to reproductive fitness. The objective of this review was the Y-chromosome...

Foram caracterizados geneticamente, utilizando-se cinco locos de microssatélites, 235 indivíduos de seis plantéis de tilápia (Ceará, Chitralada, Israel, Nilótica, Taiwan e Vermelha) da região Sudeste do Brasil. Verificou-se diferença genética entre os seis plantéis, obtida pelo cálculo do índice de fixação de alelos (Fst=0,3263). De modo geral, está ocorrendo perda de heterozigose nos plantéis, segundo mostrou a estimativa do coeficiente de endogamia intrapopulacional (Fis=0,0486). Os plantéis Israel e Nilótica foram os mais semelhantes geneticamente (Ig=0,6663). Os plantéis Chitralada e Taiwan foram os que menos apresentaram genes em comum (Ig=0,2463). O plantel denominado Vermelha foi o mais distinto entre todos.

Autores: BRITO, L. G.; BORJA, G. E. M.
Dípteras hematófagos são importantes parasitas dentro de sistemas de produção de bovinos, especialmente em confinamento. Haematobia irritans, a mosca-dos-chifres, é uma das espécies que maiores problemas causa em sistemas de produção de bovinos, dado ao intenso estresse que impõe aos animais. Um importante aspecto quando se estuda a variabilidade genética dentro das espécies é o estudo da estrutura geográfica destas populações. Buscando-se estimar a similaridade genotípica das diferentes populações brasileiras e latinoamericanas da mosca-dos-chifre utilizou-se a técnica do DNA polimórfico amplificado ao acaso (RAPD-PCR), que mostrou-se eficiente para tal propósito.

Caracterización del Crecimiento en el Primer Año de Cultivares de Espárrago (Asparagus officinalis L.) en Maceta
Provedor de dados: 113
Autores: Pertierra,Rosa; Campos,Jorge; Carrasco,Francisco.
Para evaluar el crecimiento de cuatro cultivares de espárrago (Asparagus officinalis L.) durante el primer año desde siembra se estableció un ensayo en la Provincia de Ñuble (36°34’ lat. Sur, 72°06’ long. Oeste, 144 m.s.n.m). Los cultivares evaluados fueron: Atlas, UC157F1, JWC1 y UC157F2. Se observó una alta correlación positiva entre la acumulación de biomasa y el tiempo (días desde siembra) y también con la temperatura. El modelo lineal biomasa vs. tiempo obtuvo una alta correlación (r = 0,96), por lo que no sería necesario contar con datos climáticos para estimar el crecimiento del espárrago en esta etapa. La inclusión de la radiación fotosintéticamente activa al modelo termal lineal no contribuyó a mejorarlo. Los modelos lineales y por ende las tasas...

Aujeszky's disease virus (ADV) belongs to Herpesviridae family and is an important etiological agent which infects pigs causing economic losses in swine producing countries worldwide and international trade restrictions to products of swine origin. An eradication program for ADV was established in Santa Catarina State since 2001. The last outbreak was reported in July 2004 and since then none has been reported. The disease has been controlled with the use of a genetic modified vaccine and elimination of seropositives. Aiming the characterization of ADV isolated in the South of Brazil in the last twenty years (1983-2003), a retrospective study based on the genomic analysis of the isolates through a digestion of viral genomic DNA with restriction enzyme Bam...

Carbon Dioxide Emission Scenarios for the USA
Provedor de dados: 31
Autores: Tol,   Richard S.J.
A model of carbon dioxide emissions of the USA is presented. The model consists of population, income per capita, economic structure, final and primary energy intensity per sector, primary fuel mix, and emission coefficients. The model is simple enough to be calibrated to observations since 1850. The model is used to project emissions until 2100. Best guess carbon dioxide emissions are in the middle of the IPCC SRES scenarios, but incomes and energy intensities are on the high side, while carbon intensities are on the low side. The confidence interval suggests that the SRES scenarios do not span the range of not-implausible futures. Although the model can be calibrated to reflect structural changes in the economy, it cannot anticipate such changes. The...

Carbon Leakage Revisited: Unilateral Climate Policy with Directed Technical Change
Provedor de dados: 31
Autores: Di Maria,   Corrado; van der Werf,   Edwin.
A common critique to the Kyoto Protocol is that the reduction in emissions of CO2 by countries who comply with it will be (partly) offset by the increase in emissions on the part of other countries (carbon leakage). This paper analyzes the effect of technical change on carbon leakage in a two-country model where only one of the countries enforces an exogenous cap on emissions. Climate policy induces changes in relative prices, which cause carbon leakage through a terms-of-trade effect. However, these changes in relative prices in addition affect the incentives to innovate in different sectors. We allow entrepreneurs to choose the sector for which they innovate (directed technical change). This leads to a counterbalancing induced-technology effect, which...

O objetivo deste trabalho foi quantificar o carbono da biomassa microbiana (CBM) e do CO2 (CCO2) liberado, a micorrização, fertilidade e a produtividade do milho em razão do manejo do solo e da calagem aplicada à superfície. Para tanto, instalouse um experimento com quatro tratamentos constituídos de dois manejos do solo, plantio direto (PD) e cultivo mínimo (CM), com e sem calcário (0 e 2 t ha1), com quatro repetições. Os manejos afetaram os atributos químicos do solo na camada 00,10 m: o maior valor de P foi observado no CM e o menor de Al no PD. Uma vez que não foram observadas diferenças significativas entre tratamentos para as variáveis microbiológicas e produtividade de milho, isto permite afirmar que é possível evitar a interrupção do PD com...

Carcass and meat quality of different pig genotypes in an organic extensive outdoor fatting system
Provedor de dados: 21
Autores: Weissmann, Friedrich; Fischer, Klaus; Biedermann, Günter.
Carcass, meat, and fat quality were evaluated of 37 castrates of 4 different genotypes [Pi*Du*GLR (10), Pi*AS (7), Du (10), Du*GLR (10)] kept on grass clover and fed with coarse meal made up of farm grown cereal and grain legumes without optimising the amount of amino acids and their relation to the energy content. Due to the energy surplus in the diet and in relation to the diminishing muscularity of the genotypes (corresponding to the above-mentioned sequence) lean meat contents were on a low level whereas intramuscular fat contents increased distinctly. Sensory meat quality was only at a medium level and did not differ noticeably between the genotypes. It is concluded that adipose carcasses associated with increased intramuscular fat contents do not...

Cardiotoxic effects of venoms from Chironex fleckeri and Chiropsalmus sp. on an invertebrate model
Provedor de dados: 80
Autores: Carrette,T.; Seymour,J.
Extracted venoms from two species of cubozoan, Chironex fleckeri (C. fleckeri)and Chiropsalmus sp., were injected into the freshwater crayfish Cherax quadricarinatus (C. quadricarinatus). By means of a Vascular Doppler, the cardiac parameters heart rate and contraction amplitude were recorded, with the theoretical total heart output calculated from these two recordings. Cherax quadricarinatus reflects prey items utilized by these two species in the wild and so comparisons of venom action on this animal have greater ecological relevance than those of previous mammalian models used. While the results of this study reflect previous research showing that the overall potency of C. fleckeri venom is greater than that of Chiropsalmus sp. venom, the action of the...

Autores: Orsi,Antonio M.; Domeniconi,Raquel F.; Artoni,Silvana Martinez B.; Filho,Joffre G.
Light microscopy analysis of the mural structure of the common carotid artery, internal carotid artery and external carotid artery in mongrel dog revealed variability in the middle values of vascular diameter and thickness of the intimal plus medial coats and adventitial coat. The vascular diameter did not differ between the internal carotid artery and external carotid artery, but was significantly increased in the common carotid artery from which the other two arteries had origin. The increased thickness of the intimal plus medial coats of the common carotid artery revealed the constant mechanical adjustment of the arterial wall and local shearing stress that occurred among the arterial coats. The adventitial coat of the internal carotid artery was...

In 2003 and 2004, 3 cruises were organized using observations systems and sampling techniques to carry out cartography and stock assessment of the Slipper-limpet population (Crepidula fornicata) in the bay of Mont-Saint-Michel (Western Channel). This was done as part of the National Programme of Coastal Environment (Programme National d'Environnement Côtier - PNEC). The study helped to update previous data collected in 1995-96 with similar techniques : side-scan-sonar and submarine video for observation, and scuba diving and grabs for samples collection. Results show that during an eight years period, the limpet population spread in the southern part of the bay and that its stock rose about 50%, reaching about 150,000 metric tons, south of a...

CAS role in the brain apoptosis of Bufo arenarum induced by Cypermethrin
Provedor de dados: 47
Autores: Izaguirre,M. F.; Vergara,M. N.; Casco,V. H.
CAS might have a key role in the apoptosis induced by toxins, acting as anti-apoptotic factor, stimulating the cellular proliferation and the cell contact stabilization. To start to elucidate their role in the brain apoptosis of Bufo arenarum induced by cypermethrin (CY), the expression patterns of CAS and several cell adhesion molecules (CAMs) were established. Bufo arenarum tadpoles of the control and acute bioassay survival at different doses (39, 156, 625 and 2,500 µg CY/L) and times (24, 48, 72 and 96 h) of CY treatment were fixed in Carnoy, embedded in paraffin and sectioned. CAS and CAMs expression was determined by immunofluorescence and immunohistochemistry, respectively. When the bioassay starts, CAS increases suggesting a proliferative or...

Case Studies of Strategic Alliances in U.S. Beef Production
Provedor de dados: 31
Autores: Gillespie,   Jeffrey M.; Bu,   Angel; Boucher,   Robert W.; Choi,   Won-Jun.
Calf marketing, commercial beef carcass, and natural/implant-free beef strategic alliances were examined via case study to determine alliance structure and whether each addressed risk, transaction costs, capital availability, and other concerns. All alliances were structured differently through vertical or horizontal coordination, and each had been established within the past 12 years. Alliance administrators reported that an advantage to cow-calf producers was higher cattle prices received relative to producers outside the alliances. The alliances reduced transaction costs and increased information flow among segments. Alliances did not specifically address risk or increased access to capital for technology adoption or expansion purposes.

Case-study forty-year historical analysis of production and resource use on northern Victoria dairy farming
Provedor de dados: 31
Autores: Melsen,   Monique G.; Armstrong,   Dan P.; Ho,   Christie K.M.; Malcolm,   Bill; Doyle,   Peter T.
Recent analysis from surveys of dairy farms has shown that despite large increases in production, the productivity gains on these farms have been modest. Productivity gains are important for farm viability, farmers have made production gains through adoption of technologies and increases in scale. This long-term farm case study of an irrigated dairy farm over a 40-year period provides an in-depth analysis of system changes and management complexity. Detailed records of milk production, herd, farm area and infrastructure, water use, supplementary feed, and labour were collected and pasture consumption was estimated. Changes in milk production were analysed in relation to individual resources, particularly farm inputs. Increases in production were associated...

Cassava as drought insurance: Food security implications of cassava trials in Central Zambia
Provedor de dados: 31
Autores: Barratt,   N.; Chitundu,   D.; Dover,   O.; Elsinga,   J.; Eriksson,   S.; Guma,   L.; Haggblade,   M.; Haggblade,   Steven; Henn,   T.O.; Locke,   F.R.; O'Donnell,   C.; Smith,   C.; Stevens,   T.
Wide, weather-induced fluctuations in maize production lead to recurrent food shortages in Zambia's maize consuming regions, while the cassava-growing regions of the north enjoy stable food production, even in drought years.  Noting this striking correlation between drought vulnerability and the prevalence of maize as a staple food, a growing array of agencies in Zambia has begun introducing highly productive new cassava varieties, developed in the north, to more central and southerly regions in an effort to provide low-cost food security during drought years.  Yet agroecological conditions in these drought-prone regions differ significantly from the northern research stations where Zambian scientists developed the new cassava varieties.  So it is not...

Cat, cougar, and jaguar spermatogenesis: a comparative analysis
Provedor de dados: 52
Autores: Costa,Deiler Sampaio; Paula,Tarcízio Antônio Rêgo; Matta,Sérgio Luiz Pinto da.
This work presents a comparative review about the spermatogenic process in cats (Felis domestica), jaguars (Panthera onca) and cougars (Puma concolor), with emphasis on testicular biometry, gonadossomatic index, volumetric proportion of testicular parenchyma components, tubular diameter, seminiferous epithelial height and seminiferous tubule length. It was an approach of the differences among the cell proportions that allowed conclusions about the overall yield of spermatogenic process and Sertoli cell index in three feline species.

Catch Crops in Organic Farming Systems without Livestock Husbandry - Simulations with the DAISY model
Provedor de dados: 21
Autores: Müller, Torsten; Thorup-Kristensen, Kristian; Magid, Jakob; Jensen, Lars Stoumann; Hansen, Søren.
This paper presents simulations of the soil-plant-atmosphere model DAISY based on an organic crop rotation with incorporation of different catch crops following pea as a leguminous cash crop. Special emphasise was put on the simulation of N-mineralisation/-immobilisation and of soil microbial biomass N. The DAISY model was able to simulate soil mineral N and soil microbial biomass N after soil incorporation of catch crop plant residues to some extend. Several processes need further attention and may be integrated into the DAISY model: (1) soil tillage induced mobilisation of organic material including considerable amounts of organic N, (2) winter killing of sensitive plant species and varieties, (3) decomposition of plant residues at the soil surface as...

Cats and Goat Whey Associated with Toxoplasma gondii Infection in Pigs
Provedor de dados: 21
Autores: Meerburg, B.G.; Van Riel, J.W.; Cornelissen, J.B.; Kijlstra, A.; Mul, M.F.
In organic livestock production systems, farm-management factors are thought to play an important role in the on-farm prevalence of Toxoplasma gondii. Serological results and the results of an HACCP analysis were combined to determine important risk factors for the prevalence of this protozoan parasite. Mathematical analysis demonstrated that feeding goat whey to pigs and the presence of a high number of cats were positively correlated to T. gondii seroprevalence in pigs. Not covering roughage and the farmers' assumption that pigs can come into contact with cat feces also showed a positive relationship. In order to decrease the risk of T. gondii infecting their pigs, farmers should limit the access and number of cats on their farms and refrain from feeding...

Cattle trade and the risk of importing animal diseases into the Netherlands
Provedor de dados: 31
Autores: Achterbosch,   Thom J.; Dopfer,   Dorte D.V.
This study examines the risk of importing animal diseases into the Netherlands through livestock trade. It presents projections of Dutch cattle imports until 2010, and applies quantitative epidemiology to estimate the related probabilities of importing three animal diseases (foot and mouth disease, bovine tuberculosis, and leptospirosis). A key result is that trade flows involving large numbers of cattle from a large number of small-scale farms poses alarming risks to veterinary health in the Netherlands.

A comparative study of skull types was done using 65 skulls obtained from three different goat breeds in Nigeria namely; Red Sokoto, Sahel and West African Dwarf. A unique depression was consistently found at the cornual end of the temporal line of the skull medial to the middle portion of the caudal boundary of the orbit and dorsal to the lateral portion of the parietofrontal suture. The depression was found in all the breeds studied, and in both sexes on the lateral sides of both cornual processes of the frontal bones. The features (depth, height and width) of the depression were found to vary without regard to either sex or breed. A search of the literature did not yield any information on this depression in the skull of the goat. Consequently, we...

Causal Factors and Costs of Home Plumbing Corrosion: An Investigation of Sample Selection Bias
Provedor de dados: 31
Autores: Kleczyk,   Ewa J.; Bosch,   Darrell J.
High incidences of pinhole leaks, which occur in home plumbing due to pitting corrosion of water pipes, have been observed in parts of the U.S. such as the Maryland suburbs of Washington D.C.  This research evaluates factors associated with pinhole leak occurrences and assesses the costs incurred by consumers from corrosion.  Statistical analysis of Maryland survey responses suggests that the probability of pinhole leak occurrences is associated with the type of pipes installed and the distance of the dwelling from a water treatment plant.  The number of leaks and location of pinhole leaks in the dwelling drive the financial costs of pinhole leak damage.  Correcting for sample selection bias influences the estimated coefficients and statistical...

Caused Related Marketing: Between Solidarity and Competition within the Italian Agri-Food System
Provedor de dados: 31
Autores: Vastola,   Antonella P.
Today’s consumers demand products and services not only with proven intrinsic quality features but also endowed with non-material attributes such as respect for the environmental and ethical values. These concerns are central to recent marketing developments. Cause related marketing (CRM) is a good example of the new entrepreneurial strategies able to achieve on the one hand utilitarian aims and on the other hand to contribute to a social cause through different forms of company donation. From the analysis it emerges that in Italian agri-food system three types of agents are applying CRM: companies producing widely consumed brands, with high sales volume; small companies producing high quality goods but with brands known within a limited market area; mass...

Causes of farm diversification over time: an Australian perspective on an Eastern Norway model
Provedor de dados: 31
Autores: Culas,   Richard J.
Farm planning often focuses on optimal diversification with respect to risk, where the risk-management strategies combine production, marketing, financial and environmental aspects of the farm-firm. In this study an empirical examination of diversification has been carried out using a sample of farms in Eastern Norway. Four measures of diversification (indices) were defined to record the risks in relation to income from farm production. Using these alternative measures of diversification and panel-data, the results show that larger farms are more diversified, and for farms in more favourable locations and access to labour, the farmers have a greater incentive to spread risk. These results suggest that diversification and farm size are positively linked and...

Cellular and molecular hemocyte responses of the Pacific oyster, Crassostrea gigas, following bacterial infection with Vibrio aestuarianus strain 01/32
Provedor de dados: 5
Autores: Labreuche, Yannick; Lambert, Christophe; Soudant, Philippe; Boulo, Viviane; Huvet, Arnaud; Nicolas, Jean-louis.
The strategies used by bacterial pathogens to circumvent host defense mechanisms remain largely undefined in bivalve molluscs. In this study, we investigated experimentally the interactions between the Pacific oyster (Crassostrea gigas) immune system and Vibrio aestuarianus strain 01/32, a pathogenic bacterium originally isolated from moribund oysters. First, an antibiotic-resistant V. aestuarianus strain was used to demonstrate that only a limited number of bacterial cells was detected in the host circulatory system, suggesting that the bacteria may localize in some organs. Second, we examined the host defense responses to V. aestuarianus at the cellular and molecular levels, using flow-cytometry and real-time PCR techniques. We showed that hemocyte...

Censored Probit Estimation with Correlation near the Boundary: A Useful Reparameteriztion
Provedor de dados: 31
Autores: Terza,   Joseph V.; Tsai,   Wei-Der.
The conventional computational algorithms for full information maximum likelihood (FIML) estimation of the censored probit model (see Farber, 1983), will sometimes fail to converge when the estimated value of the correlation coefficient (ñ) approaches ±1; even when the true value of ñ is not at a boundary. We show that a simple reparametrization of the censored probit model may afford straightforward Newton-Raphson convergence to the true FIML estimate for cases in which likelihood maximization under the conventional censored probit parameterization would have failed. Moreover, our method avoids the computational and inferential complications that arise in alternative methods that, based on a specified criterion, suggest fixing the estimated value of ñ at...

Centennial-scale surface hydrology off Portugal during marine isotope stage 3: Insights from planktonic foraminiferal fauna variability
Provedor de dados: 5
Autores: Vautravers, Maryline J.; Shackleton, Nicholas J.
The marine isotopic stage 3 (MIS3) at Ocean Drilling Program (ODP) Site 1060 (Gulf Stream) shows both sharp onset and end of interstadials, the existence of very short lived warm events during stadials, and points to differences in detail between the sea surface temperature (SST) record from the western North Atlantic and the atmospheric temperature record inferred from delta O-18 in Greenland ice. Investigating MIS3 and obtaining comparable data from other locations appears crucial. The eastern Atlantic provides well-documented records of climate changes. We have selected a core from off Portugal and use it to examine Dansgaard/Oeschger events (D/O) at centennial-scale resolution (139 years on average between two data points). We have obtained a faunal...

Autores: Goulletquer, Philippe.
NOAA’s National Marine Fisheries Services (NMFS) received a petition to list the Eastern oyster (Crassostrea virginica) as either threatened or endangered under the Endangered Species Act (ESA). The Eastern oyster is an emblematic species in the US coastal states, playing a significant role at various levels: shaping coastal social communities, providing a commercial activity (public fishery &amp; aquaculture) and recreational - amenity benefits, and as a keystone species in highly diverse and sensitive ecosystems (estuaries). This petition is likely the result of concerns regarding the partial collapse of public fisheries in several states as well as from the resulting damages to this species induced by severe hurricanes.

Although central vascular catheters (CVC) are indispensable in modern medicine, they are an important risk factor for primary bacteremias. We examined the incidence and risk factors associated with catheter-related bloodstream infection (CR-BSI) caused by Staphylococcus aureus in surgical patients. A prospective study was carried out in the Hospital das Clínicas da Universidade Federal de Uberlândia (HC-UFU) from September 2000 to December 2002. The skin insertion site, catheter tip, and blood were microbiologically analyzed. Demographics and risk factors were recorded for each patient, and cultures were identified phenotypically. Staphylococcus aureus was the most frequent pathogen, with an incidence rate of 4.9 episodes of CR-BSIs per 1,000...

Centralized and Decentralized Management of Local Common Pool Resources in the Developing World: Experimental Evidence from Fishing Communities in Colombia
Provedor de dados: 31
Autores: Velez,   Maria Alejandra; Murphy,   James J.; Stranlund,   John K.
This paper uses experimental data to test for a complementary relationship between formal regulations imposed on a community to conserve a local natural resource and nonbinding verbal agreements to do the same. Our experiments were conducted in the field in three regions of Colombia. Each group of five subjects played 10 rounds of an open access common pool resource game, and 10 additional rounds under one of five institutions— communication alone, two external regulations that differed by the level of enforcement, and communication combined with each of the two regulations. Our results suggest that the hypothesis of a complementary relationship between communication and external regulation is supported for some combinations of regions and regulations, but...

Recent maakte T.

Herdeterminatie van de Leidse collecties leidde tot de conclusie dat C. pumilum slechts op twee spoorweglocaties verzameld is (tussen 1975 en 1983), terwijl alle andere collecties blijken te behoren tot C. glutinosum. Het is zelfs de vraag of C. pumilum wel tot de inheemse flora van Nederland gerekend kan worden. Overigens bleek het gemakkelijk te zijn om incompleet verzamelde planten van C. fontanum (Gewone hoornbloem) te herkennen, namelijk door het bezit van lange, min of meer aangedrukte klierloze haren op de kelk in plaats van afstaande...

Cereal breeding strategies for organic and low-external-input crop production systems
Provedor de dados: 21
Autores: Acikgoz, Prof. Dr. Nazimi; Ilker, Dr. Emre.
Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions.   Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars.  Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic...

This concept intends to build two bridges. One bridge between crop management and food quality and another bridge between food quality and possible health effects for the consumer. This paper focuses on requirements for validating a concept, presenting examples from the work in the Louis Bolk Institute.

Challenges for avoiding and handling disease problems in organic herds
Provedor de dados: 21
Autores: Kijlstra, Prof. Dr. Aize.
Disease prevention in organic farming is based on the principles that an animal that is allowed to exhibit natural behaviour, that is not subjected to stress and that is fed optimal (organic) feed, will have a higher ability to cope with infectious insults than animals reared in a conventional manner. Less treatments would thus be necessary and if an animal would become diseased, alternative treatments instead of conventional drugs should be preferred. Homeopathy or phytotherapy are recommended according to the prevailing regulations. The presumptions mentioned above have not yet been substantiated by scientific evidence. No data are available showing that disease prevalence of animals held under organic conditions is lower than under conventional...

Challenges to Producer Ownership of Ethanol and Biodiesel Production Facilities
Provedor de dados: 31
Autores: Kenkel,   Philip L.; Holcomb,   Rodney B.
This study examines the rapidly expanding biofuels industry and identifies challenges for producer-owned biofuel projects.  The U.S. ethanol industry has been growing rapidly, and biodiesel production is poised for similar growth.  Producer involvement is driven by the desire to add value to farm commodities and the impact of biofuel projects on local grain prices.  Local state and federal incentives have also stimulated producer interest.  The long-run profitability of biofuel projects is driven by feedstock availability, access to market centers for biofuels, access to markets for coproducts, and utility costs and availability.  The rapidly increasing size and scale of ethanol and biodiesel plants make it difficult for producers to fund these projects....

Changes and Actual State of Mongolian Meat Market and Distribution System: A Case Study of Ulaanbaatar City's "Khuchit Shonhor" Food Market
Provedor de dados: 31
Autores: Maytsetseg,   Baljinnyam; Riichiro,   Iizawa.
With changes in the consumption pattern of meat, increases in urban population and underdeveloped distribution system after the collapse of the planned economy, there are increasing problems in meat supply and distribution in Mongolia, particularly in the capital city Ulaanbaatar. This paper examines the stages of meat distribution focusing on Khuchit Shonhor food market. Two types of informal wholesalers are identified; wholesalers who buy meat from nomads and transport it to the market in Ulaanbaatar, and wholesalers in the market who buy this meat and sell it to retailers operating within the market. It is assumed that the later wholesaler type has a stronger influence in price setting.

Autores: Mishra,Sanjay; Tyagi,Abhishek; Singh,I.V.; Sangwan,R.S.
Various lipid classes and compounds were monitored during the period of leaf emergence to leaf drop of Catharanthus roseus. The expansion to early maturation phase was accompanied by cellular build-up of all major lipid classes, whilst aging and senescence were characterized by their substantial decline, except for the neutral lipids; the leaf monogalactosyl diglyceride/digalactosyl diglyceride ratio decreased from 4.3 (complete maturity) to 2.1 (abscised stage). The early maturation stage was the earliest stage when appreciable amounts of free sterols and fatty acids could be observed. Sterol/phospholipids ratios increased by 68-fold in the abscised leaf as compared to that at full maturity. The unsaturated/saturated fatty acid ratio was far lower in the...

Farming systems research for wet-season non-rice upland crops in Cambodia is being conducted with the overall aim of poverty reduction and food security for farmers in the Provinces of Battambang and Kampong Cham. Some of these cash crops exhibit low and variable incomes, especially when grown in the early wet season. Cambodian farmers may borrow money to buy crop inputs and often sell their produce to companies and traders from neighbouring countries, hence they are price takers. Some new crop technologies are evaluated which relate to soil and crop fertility management interacting with climatic factors. The DSSAT crop simulation model is used to predict outcomes from alternative management strategies. Bio-economic analyses are conducted to assess the...

Autores: Desaunay, Yves; Guerault, Daniel; Le Pape, Olivier; Poulard, Jean-charles.
Several works have demonstrated trends in the distribution of fish species relative to global warming. This study investigated whether similar trends have occurred for selected flatfish species on the continental shelf of the Bay of Biscay. These species were used as indicators and changes in their Populations were studied in a coastal nursery ground,where flatfish juveniles are concentrated as well as on the entire shelf. Previous studies analysing changes in sea surface temperature for the continental shelf indicate that winter warming occurred in the 1980s and 1990s. Sixteen autumn cruises conducted since 1981 in the Bay of Vilaine nursery area and I I autumn cruises since 1987 over the entire shelf provided data on a nearly annual basis for the...

Provedor de dados: 61
Autores: Braga,Márcia Regina; Carpita,Nicholas C.; Dietrich,Sonia M. C.; Figueiredo-Ribeiro,Rita de Cássia L.
The thickened underground organ of Ocimum nudicaule is a tuber-like structure (xylopodium) that is dormant in winter and sprouts at the beginning of the spring. Changes in content of cell wall polysaccharides were shown to occur from dormancy to sprouting. Pectic polysaccharides of O. nudicaule were analyzed in relation to composition, molecular mass, and linkage structure in these two phenological phases. The pectin content was 33 % lower during sprouting when compared to dormancy. Changes were also observed in the molecular mass of the pectin fraction from dormancy to sprouting. Galacturonic acid was the predominant sugar, suggesting the presence of a homogalacturonan as the main pectic polysaccharide. A decrease in the acidic polysaccharides,...

Changes in Public Sector Employment with a Focus on Wisconsin 1993 to 2004
Provedor de dados: 31
Autores: Deller,   Steven C.; Maher,   Craig.
This study examines patterns of total employment growth and growth in the public sector. We use data from the 50 states with a focus on the 1993 to 2004 time period. We define the public sector with respect to state government as well as local government with the latter including counties, municipalities, K-12 public schools and special districts. We maintain that given the labor intensive nature of the public sector we can assess the size of the government by monitoring public sector employment. The results clearly suggest that Wisconsin's public sector, as measured by employment, is not "out of control" and growth in the public sector is a natural by-product of growth in the overall economy.

Changes in the phytoplankton of Lake Planetario after a restoration process
Provedor de dados: 66
Autores: Ehrenhaus,Constanza; Vigna,María Susana.
Lake Planetario is an urban recreational lake that suffered a Microcystis aeruginosa bloom in March 1999. At the same time the birds and fishes that inhabited the lake died, probably affected by microcystin, hepatotoxin that some strains of Miycrocyistis produce. The City of Buenos Aires requested Aguas Argentinas to restore the lake. Restoration tasks included treatment of sediments and pumping of water from a brackish aquifer. For one year, monthly samples were taken with a phytoplankton net, the qualitative and quantitative composition of the phytoplankton were studied, and physicochemical data were collected. The structure and composition of the phytoplankton were studied and revealed that due to the turbulence caused by the pumping of water, the...

Changes in the vertical profile of the Indonesian Throughflow during Termination II: Evidence from the Timor Sea
Provedor de dados: 5
Autores: Xu, Jian; Kuhnt, Wolfgang; Holbourn, Ann; Andersen, Nils; Bartoli, Gretta.
We use a multiproxy approach to monitor changes in the vertical profile of the Indonesian Throughflow as well as monsoonal wind and precipitation patterns in the Timor Sea on glacial-interglacial, precessional, and suborbital timescales. We focus on an interval of extreme climate change and sea level variation: marine isotope (MIS) 6 to MIS 5e. Paleoproductivity fluctuations in the Timor Sea follow a precessional beat related to the intensity of the Australian (NW) monsoon. Paired Mg/Ca and delta(18)O measurements of surface- and thermocline-dwelling planktonic foraminifers ( G. ruber and P. obliquiloculata) indicate an increase of &gt; 4 degrees C in both surface and thermocline water temperatures during Termination II.

Changes in variety composition in spring barley mixtures over years
Provedor de dados: 21
Autores: Østergård, H.; Backes, G.
In a variety mixture, competition between component varieties as well as differences in performance of the components may lead to changes in the proportion of component varieties between seed sown and seed harvested. This will imply that farm saved seeds of variety mixtures will constitute an evolving population. How much changes are found over a short period of years and in different environments?  In 2002, six 3-component variety mixtures of spring barley were constructed based on altogether 14 mostly high-yielding varieties. The six mixtures and derivatives of these were included in the large Danish BAR-OF variety trials in the years 2002-2005 (Østergård et al. 2005). Here, a subset of this material is considered: only trials from 2003 and 2004 at the...

Changes in Yield Stability: Wheat and Maize in Developing Countries
Provedor de dados: 31
Autores: Gollin,   Douglas.
This study asks whether the diffusion of modern varieties has affected the yield stability of wheat and maize production in developing countries between 1960 and 2004. The data suggest strongly that, over the past forty-plus years, there has been a striking decline in the relative variability of grain yields in wheat and (to a lesser extent) maize. The declines are strongest when measured as the standard deviation of yield divided by the mean, but there have also been declines in other measures of variability, such as the percentage deviation from trend. Declines in yield variability do not appear to be driven by increases in intensification (e.g., irrigation), nor do they appear to extend to crops, such as oilseeds, in which there has been little...

Autores: Love,   Leigh Ann; Sterns,   James A.; Spreen,   Thomas H.; Wysocki,   Allen F.
From 2000 through 2004, per capita orange juice purchases decreased by 12.3 percent while the popularity and media coverage of low-carbohydrate dieting exploded.  Content analysis was used to count selected Southern region newspaper articles topically related to low-carbohydrate dieting, the Atkins diet, and the South Beach diet.  This data was included in a Southern region orange juice demand model, where purchase data served as the independent variable and proxy for consumer demand of orange juice.  Results indicated that media coverage of low-carbohydrate diets and dieting was negatively and significantly related to demand for orange juice in the Southern region.

Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, M&amp;#246;ja and Orn&amp;#246; parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners.

Corn production costs per bushel vary considerably among U.S. producers, depending on yields, farm location, tillage practices, irrigation, previous field usage, enterprise size, and weather. In 2001, the operating and ownership costs per bushel for corn ranged from an average of $1.08 for the 25 percent of U.S. producers with the lowest costs to an average of $2.98 for the 25 percent with the highest costs. Heartland corn producers had the lowest costs per bushel on average. Corn producers with small corn enterprises had the highest costs due to their lower-than-average corn yields. Operators of part-time and low-sales corn farms have higher production costs per bushel than operators of farms with higher sales. In 2001, 59 percent of corn producers earned...

The present study deals with the isolation and characterization of the moderately halophilic-alkaliphilic bacteria from a saline habitat in western India. Eight different bacterial strains were isolated using enrichment techniques at 20% (w/v) NaCl and pH 10. The isolates exhibited diversity towards gram's reaction, colony and cell morphology. They were able to grow and produce alkaline protease over a broad range of NaCl, 5-20% (w/v) and pH, 8-10. None of the isolates could grow at pH 7, and one could not grow even at pH 8. Crude and partially purified proteases from strain S5 were subjected to characterization with reference to pH, salt stability and protein folding. Optimum protease activity and stability was recorded at 10% salt and pH 9-9.5....

The aim of the present work was to examine the modifications of the organic composition of fish endolymph under environmental conditions (day-night cycle, starvation and Cl-2-Stress) known to modify otolith growth. Endolymph electrophoretic patterns were compared. An antibody raised against the trout otolith organic matrix allowed examining the variations of organic matrix precursors in the endolymph under the above conditions. Western blot analysis showed bands around 60-80 kDa. A 50% decrease of immunolabelling was observed during the night whereas increases were seen after starvation (factor 3) or stress (factor 2) suggesting that these variations could be related to the organic matrix deposit. A factor retarding in vitro CaCO3 crystallization (FRC) was...

In invertebrates, defensins were found in arthropods and in the mussels. Here, we report for the first time the identification and characterization of a defensin (Cg-Def) from an oyster. Cg-def mRNA was isolated from Crassostrea gigas mantle using an expressed sequence tag approach. To gain insight into potential roles of Cg-Def in oyster immunity, we produced the recombinant peptide in Escherichia coli, characterized its antimicrobial activities, determined its solution structure by NMR spectroscopy, and quantified its gene expression in vivo following bacterial challenge of oysters. Recombinant Cg-Def was active in vitro against Gram-positive bacteria but showed no or limited activities against Gram-negative bacteria and fungi. The activity of Cg-Def was...

Nowadays, there is a tendency of use of low temperature in laundry cleaning for both environmental and economical reasons, which makes the use of enzymes in detergent products indispensable. Since lipases are efficient catalyst both in solution and at the water-liquid interface, they are potentially suitable for lipid stain removal applications in industrial laundry and household detergents. The effect of different commercial detergents and surfactants on enzymatic activity of lipase from Fusarium oxysporum was observed through p-nitrophenylpalmitate (pNPP) assay. The enzyme was compatible with various ionic and non-ionic surfactants as well as commercial detergents. Lipase activity was strongly inhibited by Sodium Dodecyl Sulphate (SDS), but not by Triton...

Despite the possible influence of tannins on the nutritional value of the forages from Caatinga vegetation, there are few studies that evaluated their tannin concentration. This study was conducted to characterize condensed tannins present in the legumes species Mimosa hostilis (Jurema Preta), Mimosa caesalpinifolia (Sabiá) and Bauhinia cheilantha (Mororó), at three stages of their phenological cycle. The concentration of soluble tannin (ST), bound tannin (BT) and total tannin (TT) were determined using the butanol-HCL method; astringency was by the radial diffusion method, and the monomeric composition of purified tannins by a high-performance liquid chromatograph with delphinidin, cyanidin and pelargonidin as standards. Concentration and astringency of...

Characterization of different strains of common carp (Cyprinus carpio L.) (Cyprinidae, Cypriniformes) in Bangladesh using microsatellite DNA markers
Provedor de dados: 74
Autores: Mondol,Rashedul Kabir; Islam,Shahidul; Alam,Samsul.
Characterization of different strains of common carp (Cyprinus carpio L.) using molecular markers is essential for the management of this fish in respect to the evaluation of the potential genetic effects induced by hatchery operations and the genetic improvement of carp varieties. Five microsatellite loci (MFW1, MFW2, MFW11, MFW15 and MFW20) were analyzed for the molecular characterization of four common carp strains, i.e. scaled carp, mirror carp, red carp and koi carp. We observed differences in heterozygosities and the average numbers of alleles but not in polymorphic loci (P95) among the strains. Koi carp displayed the highest level of variability in terms of heterozygosity. The Nm values and the F ST values indicated a low level of gene flow and high...

Characterization of insecticidal peptides from venom Australian funnel-web spiders
Provedor de dados: 80
Autores: Vonorax,E. J.; Tyler,M. I.; Atkinson,R. K.; Howden,M. E. H.
Australian funnel-web spiders are relatively large primitive hunting spiders. Male Atrax robustus spiders have been responsible for a number of human deaths. Venom was collected from the species Hadronyche infensa (Hickman) [female], H. formidabilis [male and female], H. versuta [female], and A. robustus (Cambridge) [male] and was fractionated by high performance liquid chromatography. This resulted in the isolation and purification of a homologous series of 7 insecticidal peptides of relatively low molecular mass (approximately 4kDa). The amino acid sequences of these toxins consisted of 36 or 37 amino acids and were named atracotoxins. For the major bioassay of these toxins, we used the cotton bollworm, Helicoverpa armigera (Hubner), due to the great...

Characterization of mitochondrial iron uptake in HepG2 cells
Provedor de dados: 48
Autores: MAZARIEGOS,DORA INÉS; CABANTCHIK,Z. IOAV; CASSELS,BRUCE K; NÚÑEZ,MARCO TULIO.
There is increasing evidence that accumulation of redox-active iron in mitochondria leads to oxidative damage and contributes to various neurodegenerative diseases, such as Friedreich's ataxia and Parkinson's disease. In this work, we examined the existence of regulatory mechanisms for mitochondrial iron uptake and storage. To that end, we used rhodamine B- [(1,10-phenanthrolin-5-yl)amino carbonyl ] benzyl ester, a new fluorescent iron-sensitive probe that is targeted specifically to the mitochondrion. We found that extracellular iron was incorporated readily into mitochondria in an apparently saturable process. Moreover, the rate of iron incorporation responded to the Fe status of the cell, an indication that the mitochondrion actively regulates its iron...

Characterization of residual stresses in wound composite tubes
Provedor de dados: 5
Autores: Casari, Pascal; Jacquemin, Frederic; Davies, Peter.
This paper presents a method for the characterization of residual stresses in thick filament wound tubes. The three materials considered in the study are wet wound epoxy composite tubes based on E glass, R glass and T700 carbon fibres with three winding angles, [+/- 35], [+/- 55] and [+/- 851 with respect to the longitudinal axis. The aim of the present work is to measure internal stresses, based on strains liberated by cutting composite tubes, and to compare results with predictions from a residual stress model based on the classical equations of solid mechanics. This leads to a simple technique which allows the quick identification of the effects of manufacturing and moisture on the internal multi-axial stress level.

Characterizing Species at Risk I:  Modeling Rare Species Under the Northwest Forest Plan
Provedor de dados: 7
Autores: Marcot, Bruce G; USDA Forest Service; bmarcot@fs.fed.us.
The Northwest Forest Plan in the Pacific Northwest, United States includes directives for survey and site protection of hundreds of rare species across many taxonomic classes. To help direct survey activities, prioritize sites, and stand conditions for conservation of these species, I developed Bayesian belief network (BBN) models of habitat relationships and multiple stressors predicting presence of 12 rare species, and I present an example of predicting presence and absence of a rare fungus. The BBN models are developed along a rigorous process of expert judgment, peer review, reconciliation, accuracy testing, and incremental updating with known site data and validation data. Management implications of prediction errors are discussed.

We developed a set of decision-aiding models as Bayesian belief networks (BBNs) that represented a complex set of evaluation guidelines used to determine the appropriate conservation of hundreds of potentially rare species on federally-administered lands in the Pacific Northwest United States. The models were used in a structured assessment and paneling procedure as part of an adaptive management process that evaluated new scientific information under the Northwest Forest Plan. The models were not prescriptive but helped resource managers and specialists to evaluate complicated and at times conflicting conservation guidelines and to reduce bias and uncertainty in evaluating the scientific data. We concluded that applying the BBN modeling framework to...

Chasing Absolute Cost and Profit Savings in a World of Relative Inefficiency
Provedor de dados: 31
Autores: Atkinson,   Scott E.; Dorfman,   Jeffrey H.
Econometric models to estimate allocative and technical inefficiency include stochastic shadow distance frontiers, shadow  cost frontiers, and shadow profit frontiers. In these models, the cost savings from eliminating both sources of inefficiency is  often reported in total and then decomposed into the contribution of each source.  This paper shows that this calculation, as formalized in Kumbhakar (1997) and used extensively in empirical applications over the last 25 years, is non-unique without  additional information that is  typically not available. The same results are obtained for shadow profit and shadow distance systems. The decomposition of cost (profit) savings is underidentified, since it is conditional on the arbitrarily normalized value for...

Taim Hydrological System is a unique subtropical wetland in southern Brazil harboring an exceptional biological diversity. In 1978, an ecological reserve was established to protect part of this area from increasing anthropogenic impacts in its surroundings. Fishes have been poorly investigated in this system. Based on a multi-gear sampling study encompassing several years (2001-2005), and on comparisons with previous fish inventories, we provide an up-to-date species list of fishes occurring in the Taim Wetland. In addition, we made the first preliminary description of fish dominance patterns found in the main lakes of the system (Flores, Nicola, Jacaré and Mangueira). Checklist comparison resulted in 62 fish species distributed in 24 families, with...

Sugar cane silage has a potential for animal feeding, but uncontrolled growth of undesirable microorganisms may cause nutritional losses and affect the animal productivity and health. The objective of this work was to evaluate the microbiological quality and chemical composition of ensiled sugar cane with and without nutritional additives after 30 days of fermentation. Yeasts, filamentous fungi and distinct groups of bacteria were enumerated by plate count methods and the chemical analyzes comprised dry matter, crude protein, fiber content, lignin, and pH. Facultative aerobic bacteria and filamentous fungi were not detected during the fermentative process in any of the treatments. The number of yeasts in five varieties of sugar cane silage without...

Chemical communication between roots and shoots: towards an integration of aboveground and belowground induced responses in plants
Provedor de dados: 26
Autores: Van Dam, N.M.; Bezemer, T.M.
Induced responses in plants occur in response to both aboveground (AG) and belowground (BG) herbivores and pathogens. So far, the majority of studies have focused on AG induced responses. Possible interactions between AG and BG induced responses have only recently received scientific attention. On the one hand, induction in one plant part may result in systemically induced responses in other parts. On the other hand, simultaneously occurring AG and BG induced responses may interfere, for example, when the activities of root feeders alter the effectiveness of induced responses against leaf feeders. In both cases, AG–BG interactions between induced responses may affect the amount of damage to a plant and therefore constitute an important selection pressure...

Chemical communication: five major challenges in the post-genomic age
Provedor de dados: 26
Autores: Penn, D.J.
Chemical signals play an important role in the behaviour of most, if not all, organisms, but we still have much to learn about this mode of communication. Here I examine some of the major challenges to understanding chemical communication, especially for vertebrates, and consider how genomics, proteomics, metabolomics, and other ‘-omics’ sciences and technologies provide new opportunities to address many of these challenges. First, one of the major challenges of this field is to better understand the kinds of information chemical signals provide. A second challenge is to unravel the proximate mechanisms that control chemical communication (i.e., the production and composition of chemosignals and olfactory recognition). Progress has been advancing rapidly...

Chemical ecology: a multidisciplinary approach
Provedor de dados: 26
Autores: Takken, W.; Dicke, M.
Chemical information conveyance is an important phenomenon in the biology of plants and animals. This involves intraspecific chemical communication and its exploitation by heterospecific organisms. As a result food webs are overlaid with information webs that can have important consequences for community processes. A vast amount of research shows that both the emission of chemical information and the responses to it are often genetically controlled, and mediated by numerous interactions between an individual and its environment. Overall, it is argued that ecosystem functioning is much dependent on the responses of various community members to chemical cues, and that therefore knowledge on the chemical communication, from the genetic level to the ecosystem,...

Chemical ecology from genes to communities: integrating 'omics' with community ecology

Autores: Dicke, M.
Chemical cues that convey information are widely used by living organisms. The cues mediate interactions in food webs as well as non-trophic interactions such as interactions between conspecific organisms or between plants and natural enemies of herbivorous organisms. Communities are composed of food webs and each food web is overlaid with a reticulate infochemical web that is more complex than the underlying food web. Chemical ecology has addressed the role of information conveyance in intraspecific and interspecific interactions and has mostly concentrated on elucidating the identity of chemicals and their role in individual interactions of food webs. In addition, the role of infochemicals has been investigated in multitrophic interactions. Recently,...

Parasitic plants in the Orobanchaceae use chemicals released from host-plant roots to direct developmental processes crucial to their heterotrophic lifestyle. An illustrative example is the development of haustoria; parasite root organs that function in host attachment and penetration, and in the establishment of a physiological conduit through which host resources are robbed. The facultative parasite Triphysaria develops haustoria only in the presence of host roots or host root factors. An in vitro assay was used to identify several phenolic derivatives that induce haustorium formation; the activity of multiple signalling molecules is consistent with a redundancy of active molecules in the rhizosphere triggering haustorium development.

A Permian bentonite deposit at Melo, Uruguay is composed of a calcite-cemented sandstone containing clay pseudomorphs of glass shards (0-0.50 m) overlying a pink massive clay deposit (0.50-2.10m). The massive bed is composed of two layers containing quartz and smectite or pure smectite respectively. The smectite is remarkably homogeneous throughout the profile: it is a complex mixed layer composed of three layer types whose expandability with ethylene glycol (2EG 1EG or 0EG sheets in the interlayer zone which correspond to low-, medium- and high-charge layers respectively) varies with the cation saturating the interlayer zone. The smectite homogeneity through the profile is the signature of an early alteration process in a lagoonal water which was over...

The avoidance responses of aphid parasitoids with varying host ranges (Aphidius eadyi, Aphidius ervi, and Praon volucre) to chemical trails deposited by intraguild predatory ladybirds, Coccinella septempunctata and Adalia bipunctata, were investigated. Females of all three parasitoid species avoided leaves previously visited by C. septempunctata or A. bipunctata adults. The avoidance responses shown by the two Aphidius species were stronger to trails of C. septempunctata than to those of A. bipunctata. However, P. volucre avoided trails of both ladybird species to a similar degree. Dose responses of these three parasitoid species to the hydrocarbons n-tricosane (C23H48), n-pentacosane (C25H52), and n-heptacosane (C27H56), which are components of the trails...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the human central nervous system. Although its etiology is unknown, the accumulation and activation of mononuclear cells in the central nervous system are crucial to its pathogenesis. Chemokines have been proposed to play a major role in the recruitment and activation of leukocytes in inflammatory sites. They are divided into subfamilies on the basis of the location of conserved cysteine residues. We determined the levels of some CC and CXC chemokines in the cerebrospinal fluid (CSF) of 23 relapsing-remitting MS patients under interferon-ß-1a therapy and 16 control subjects using ELISA. MS patients were categorized as having active or stable disease. CXCL10 was significantly...

CH-FARMIS 2.0: A Sector-Model to Assess the Economic and Environmental Impacts of Swiss Direct Payment Schemes
Provedor de dados: 21
Autores: Schader, Christian; Sanders, Jürn; Lampkin, Nic; Stolze, Matthias.
Quantitative sector models are an essential tool to forecast the sector-wide economic effects of agricultural policies. However, to cover ecological effects with economic sector models is still a methodological challenge. This poster describes a promising approach, which is currently implemented at the Research Institute of Organic Agriculture (FiBL) to meet this challenge.  CH-FARMIS is a sector consistent farm group model, which is able to forecast economic impacts of policies on farm, regional and sector-level. In a flexible way, CH-FARMIS is able to split up the farm sector in farm groups according to various characteristics (region, farming system, farm type, etc.). CH-FARMIS is based on positive mathematical programming (PMP) to allow for a realistic...

CH-FARMIS - An agricultural sector model for Swiss agriculture
Provedor de dados: 21
Autores: Sanders, Jürn.
This working paper gives an overview of the farm group model CH-FARMIS - a comparative static, process analytical, non-linear programming model that allows a separate assessment of the impacts of policies on organic and non-organic farming in Switzerland. In CH-FARMIS, the agricultural sector is represented by thirty farm groups, which can be char-acterised by their farming system, farm type and geographic location. Book keeping data from the Swiss FADN was used as a primary source for the model. By applying farm-specific weight-ing factors, farm data were aggregated to sector accounts. The technical coefficients of the farm model were either taken directly from farm accounts or calculated on the basis of normative data. Agricultural production is...

Chicken serologic response to Salmonella enterica serotype Typhimurium assessed by Elisa
Provedor de dados: 89
Autores: Oliveira,GH; Berchieri Jr,A; Montassier,HJ.
This study evaluated two enzyme-linked immunosorbent assays (ELISA) in the detection of chicken serologic response against Salmonella enterica sorotype Typhimurium. The assays have used as detecting antigen the soluble bacterial proteins of a non-flagellated strain of Salmonella Typhimurium (AgTM), and antibody conjugated to peroxidase or alkaline phosphatase. According to the results, optimal dilutions of antigen (concentration 5.49 mg/mL) and serum samples in both assays were 1:20,000 and 1:1,000, respectively. In such conditions, the ELISA/AgTM was able to detect serological response to Salmonella Typhimurium. Cross-reactions to Salmonella serotypes Gallinarum and Pullorum were seen, but not with other serotypes such as Enteritidis.

Children's Educational Completion Rates and Dropouts in the Context of Ethiopia's National Poverty Reduction Strategy
Provedor de dados: 31
Autores: Woldehanna,   Tassew; Jones,   Nicola; Tefera,   Bekele.
A combination of quantitative and qualitative method was used to analyse the determinants of school completion/dropout of children from primary education. A Cox box proportional hazard model was used analyse the survival of children in primary education. The findings have important implications for the formulation and revising Ethiopian Poverty Reduction Strategy Paper. While the policy focus of the 1996-initiated ESDP and the SDPRP (2002-5) on increasing educational access for all has been broadly successful, children from poor and/or highly indebted families still face significant constraints because they have to contribute to household survival through paid and unpaid work. It is therefore imperative to increase efforts to improve the livelihood options...

China's Biotech Policies and Their Impacts on U.S. Agricultural Exports to China
Provedor de dados: 31
Autores: Song,   Baohui; Marchant,   Mary A.
China is a key player in global agricultural markets, and the number one importer of U.S. soybeans and cotton, whereby soybeans and cotton are two of the main biotech commodities commercialized in the United States. As of 2005, 87% of soybeans and 79% of cotton planted in the U.S. were biotech. Thus, changes in China's biotech policies may have a significant impact on U.S. biotech commodity exports to China. An understanding of the evolution of China's biotech regulations and factors that may influence China's future biotech policies is crucial for both U.S. producers and policymakers. This article introduces the development of China's biotech regulations in detail. Focusing on soybeans and cotton, the impact of China's biotech policy changes on U.S. trade...

China's Economic Performance and Transition in Relation to Globalisation: From Isolation to Centre-Stage?
Provedor de dados: 31
Autores: Tisdell,   Clement A.
This paper considers China’s global economic situation in relation to the general process of globalisation.  After discussing the general process of economic globalisation, it examines political change and transition of the former communist planned economies, especially China’s, and their impact on globalisation.  Then it provides measures of the recent expansion of economic globalisation and China’s involvement in this process.  Positive and negative socioeconomic impacts of globalisation are highlighted.  China’s progress in catching up with more developed economies and the dynamics of its economic growth and future prospects for this growth are examined in a global context.  The question is posed of whether globalisation is likely to result in...

China's Expanding Role in Global Horticultural Markets
Provedor de dados: 31
Autores: Rae,   Allan N.; Zhong,   Funing; Zhou,   Yingheng; Geng,   Xianhui.
China's horticultural exports have almost doubled in value over the past decade, her imports have increased by even more, and China is increasingly a net exporter of horticultural products. After adjusting trade data for irregularities in the reported trade between Hong Kong and mainland China, growth in China's exports and imports is discussed. Major traded products and markets will be identified. Case studies are China's trade in fresh apples, which have become the major fruit export, and in cut flowers which are a relatively new export product for China. China's competitive position and market shares relative to other suppliers of apples and cut flowers to foreign markets are examined.

China's New Rural Income Support Policy: Impact on Grain Production and Rural Income Inequality
Provedor de dados: 31
Autores: Heerink,   Nico; Kuiper,   Marijke H.; Xiaoping,   Shi.
The impact of China's new rural income support policy and recent price trends on grain production and rural income inequality is assessed for two villages with different degrees of market access in Northeast Jiangxi Province. Two village-level general equilibrium models are used to analyze household decision making and interactions between households within these villages. Parameter estimation and model calibration is based on data collected during an extensive survey held in these villages in the year 2000. The household classification used in these models allows us to draw conclusions that are relevant for many other villages and regions in China. Simulation results show that the income support policy does not reach its goal of promoting grain...

Chinese consumer’s perceptions of beef
Provedor de dados: 31
Autores: Liu,   Hongbo; Parton,   Kevin A.; Cox,   Rodney J.
China has experienced rapid economic growth over the last 26 years. As per capita income has increased, household consumption has become greatly diversified, and many food new products have entered the market. Beef is slowly gaining ground relative to the more traditional pork products. This research examined factors affecting beef purchasing decisions in China. The effect of socioeconomic and demographic characteristics, together with other influences on preferences, was analysed using probit regression analysis. Compared with other meats, the relatively high price of beef (34%) and consumers’ unfamiliarity with its cooking method (26%) are the main limitations for beef consumption. These are followed by ‘don’t like the taste and smell’ which shows that...

Autores: Silva,Francielle Gibson da; Freitas,Julio Cesar de; Müller,Ernst Eckehardt.
A Chlamydophila abortus (anteriormente classificada como Chlamydia psittaci sorotipo 1) tem sido descrita em muitos países, associada principalmente com distúrbios reprodutivos em ovinos, bovinos e caprinos. O aborto enzoótico dos ovinos e caprinos e o aborto epizoótico dos bovinos são as doenças mais importantes causadas por esta bactéria. No Brasil, as pesquisas com C. abortus são praticamente inexistentes. O objetivo desta revisão é apresentar informações sobre modificações taxonômicas, ciclo de vida, epidemiologia, patogenia, sinais clínicos e diagnóstico da infecção por C. abortus principalmente em ovinos, bovinos e caprinos.

Autores: Romero,M. Cristina; Reinoso,Enso Hugo; Moreno Kiernan,Alejandro; Urrutia,M. Inés.
Environmental biotechnology has developed as an offshoot from sanitary engineering, and only recently the biological component of the ecosystems had been recognized as relevant when bioremediation strategies must be chosen to solve environmental problems. Yeasts were isolated on 2,4-dichlorobiphenyl, 2,3',4- and 2,4',5-trichlorobiphenyl, poorly soluble compounds in water, as carbon sources. Debaryomyces castelli, Debaryomyces maramus and Dipodascus aggregatus composed the mixed culture and represented 72% of the isolates; their degradation potential were studied in biphasic and monophasic systems. The biphasic cultures were obtained with phenol as the organic phase and MSM as the aqueous ones, the monophasic medium only with MSM. Both cultures were...

Autores: Yermolova,   Olga; Kireyeva,   Natalia; Fisenko,   Natalja.
The paper presents the results of the sociological survey and expertise describing the factors of risk reduction and increase of the level of trust in contract relations in food networks. The level of contract discipline is analyzed. It is shown that the insufficient rate of development of the institution of trust restricts the liberty of action for companies operating in a food network, deprives them of the opportunity to achieve the local optima and provides no grounds for setting their economic behavior sure-footed standards.   Following the sociological survey the dynamics and structure of the transaction costs in food networks are displayed along with the specific features of their accounting in the company’s operations.   An expertise of the most...

Choosing between the AIDS and Rotterdam models: A meat demand analysis case study
Provedor de dados: 31
Autores: Taljaard,   Pieter R.; van Schalkwyk,   Herman D.; Alemu,   Zerihun Gudeta.
Due to the inability of economic theory to choose ex ante between the Almost Ideal Demand System (AIDS) and the Rotterdam model, a non-nested test was used. The results of the non-nested test points to the Linearized-AIDS model applied to 31 years of meat consumption data in South Africa. When comparing the estimated demand relations of the two models, the LA/AIDS model also proved to be better fit for South African meat demand.

Choosing components in the additive main effect and multiplicative interaction (AMMI) models
Provedor de dados: 63
Autores: Dias,Carlos Tadeu dos Santos; Krzanowski,Wojtek Janusz.
The additive main effect and multiplicative interaction (AMMI) models allows analysts to detect interactions between rows and columns in a two-way table. However, there are many methods proposed in the literature to determine the number of multiplicative components to include in the AMMI model. These methods typically give different results for any particular data set, so the user needs some guidance as to which methods to use. In this paper we compare four commonly used methods using simulated data based on real experiments, and provide some general recommendations.

Choosing to Have Less Choice
Provedor de dados: 31
Autores: Salgado,   Maria.
This paper investigates choice between opportunity sets. I argue that individuals may prefer to have fewer options for two reasons: First, smaller choice sets may provide information and reduce the need for the agent to contemplate the alternatives. Second, contemplation costs may be increasing in the size of the choice set, making smaller sets more desirable even when they do not provide any information to the agent. I identify which of these reasons drives individual behavior in a laboratory experiment. I find strong support for both the information and cognitive overload arguments. The effects do not disappear as participants gain experience with the task. Applications of these results include firms’ choices of product variety, as costs increase with...
