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

Legumes as green manure are alternative sources of nitrogen (N) for crops and can supplement or even replace mineral nitrogen fertilization due to their potential for biological nitrogen fixation (BNF). The utilization of nitrogen by sugarcane (Saccharum spp.) fertilized with sunn hemp (Crotalaria juncea L.) and ammonium sulfate (AS) was evaluated using the 15N tracer technique. N was added at the rate of 196 and 70 kg ha-1 as 15Nlabeled sunn hemp green manure (SH) and as ammonium sulfate (AS), respectively. Treatments were: (i) Control; (ii) AS15N; (iii) SH15N + AS; (iv) SH15N; and (v) AS15N + SH. Sugarcane was cultivated for five years and was harvested three times. 15N recovery was evaluated in the two first harvests. In the sum of the three harvests,...

Autores: Nordquist,   Dale W.; Kurtz,   James N.; Nitchie,   Donald L.; Paulson,   Garen J.; Froslan,   Janet M.; Woodford,   John L.
Average net farm income was $322,165 in 2010 for the 97 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  Average earnings increased by 362%  from $69,787 in 2009 (Figure 1).  Inflations adjusted profits rebounded after a downturn in 2009 that was caused primarily by low profits in the livestock sectors.  Strong yields, substantially higher crop inventory values, and rebounding profitability of the livestock sectors led the way to much higher profits in 2010.

2011 Approaches for organic food and feed authentication
Provedor de dados: 21
Autores: van Ruth, S.M.; Alewijn, M.; Tres, A.; van der Veer, G.
People’s growing awareness of health, environment and animal welfare has led to an increased public interest in the quality of foods and food production systems. This in turn boosted organic production. Due to higher production costs, organic produce tends to retail at a higher price than their conventional counterparts. As a consequence of the premium price, organic produce is susceptible to fraud. Fair competition between producers and sustained consumer confidence favour organic production, and it requires regular confirmatory assessments of the identity of organic produce in addition to administrative controls.     Traditional analytical strategies for guaranteeing quality and uncovering adulteration have relied on the determination of the amount of a...

2011 German Escherichia coli O104:H4 outbreak: Alignment-free whole-genome phylogeny by feature frequency profiles
Provedor de dados: 17
Autores: Man Kit Cheung; Lei Li; Wenyan Nong; Hoi Shan Kwan.
Accuracy of SNP-based whole-genome phylogeny reconstruction relies heavily on quality of sequence alignment which is particularly hindered by poorly assembled genomes. Alignment-free methods might provide additional insights. Here, we constructed a whole-genome phylogeny of 10 isolates from the current German E. coli outbreak against 30 existing E. coli genomes as well as that of a historical EHEC isolate using the alignment-free feature frequency profile method. Our results revealed a high similarity among E. coli isolates from the current outbreak and the historical EHEC being the most closely related isolate sequenced thus far.

Accuracy of SNP-based whole-genome phylogeny reconstruction relies heavily on quality of sequence alignment which is particularly hindered by poorly assembled genomes. Alignment-free methods might provide additional insights. Here, we constructed a whole-genome phylogeny of 9 E.coli isolates from the 2011 German outbreak against existing E. coli genomes using the alignment-free feature frequency profile method. In addition, we looked for gene elements that distinguish the outbreak group from the other E. coli strains and possibly accounted for the emergence of the outbreak isolates using the distinguishing feature analysis.

2011 Michigan Land Values and Leasing Rates
Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value.

Net farm income in North Dakota was at record levels for most representative farms in 2010. However income in 2020 is projected to be lower than in 2010. Commodity prices are expected to decrease slowly from current levels. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit farms are expected to increase slightly.

Autores: Taylor,   Richard D.; Koo,   Won W.
This report evaluates the United States and world corn and soybean markets for the 2010-2020 period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Corn-based ethanol production has influenced United States corn industry. As long as the production of corn-based ethanol remains strong, corn prices will likely remain at a level higher than the long term average. However, changes in the U.S. Federal government subsidies or mandates could significantly impact the world corn market. Under the current assumptions in the model, corn price is expected to remain in a range between $4.68 and $5.35 per...

2C or Not 2C?
Provedor de dados: 31
Autores: Guivarch,   Celine; Hallegatte,   Stephane.
Political attention has increasingly focused on limiting warming to 2°C. However, to date the only mitigation commitments accompanying this target are the so-called Copenhagen pledges, and these pledges appear to be inconsistent with the 2°C objective. Diverging opinions on whether this inconsistency can or should be resolved have been expressed. This paper clarifies the alternative assumptions underlying these diverging view points and explicits their implications. It first gives simple visualizations of the challenge posed by the 2°C target. It then proposes a “decision tree”, linking different beliefs on climate change, the achievability of different policies, and current international policy dynamics to various options to move forward on climate change.

30-S: La vulnerabilidad del liderazgo de la Revolución Ciudadana y de la Institucionalidad en Ecuador (Coyuntura)
Provedor de dados: 122
Autores: Ortiz, Santiago.
Los hechos del 30 de septiembre, que son descritos por el autor como un intento de golpe de Estado, se desenvuelven en un nuevo escenario, ya no de crisis, sino de ‘refundación’ del Estado y de reforma institucional. En el texto se repasan tanto las coincidencias como las diferencias en relación a tres golpes de Estado previos (Bucaram, 1997; Mahuad, 2000; Gutiérrez, 2005); destacando en el del 30-S tres elementos que se analizan: reivindicaciones de base corporativa, una sublevación armada sincronizada en todo el país y acciones dirigidas a desestabilizar el régimen democrático. Se discute finalmente, la paradójica relación entre la autoridad y liderazgo del presidente Rafael Correa y el deterioro de la institucionalidad en el país.

37 years of scientific activity in a Biochemistry Department in Brazil: patterns of growth and factors leading to increased productivity
Provedor de dados: 42
Autores: Gomes,Urubatã E.; Oliveira,Diogo L. de; Berti,Luciana C.; Amaral,Olavo; Souza,Diogo O.; Wofchuk,Susana T.
Scientific activity in Brazil has experienced an accelerated growth in the past decades, with an increase in productivity that greatly surpasses the international average. This growth has occurred mostly at the expense of centers of excellence in public universities, which account for the vast majority of the country's scientific output. The aim of this study was to evaluate the production of the Department of Biochemistry of a large public university in southern Brazil (Universidade Federal do Rio Grande do Sul), as well as to identify internal and external policies that have influenced this growing production profile. We have performed a historical analysis of the scientific output of this Department of Biochemistry, which accounts for a considerable...

3D models of lamprey corticoid receptor complexed with 11-deoxycortisol and deoxycorticosterone
Provedor de dados: 17
Autores: Michael E. Baker; Kayla Y. Uh; Paiyuam Asnaashari.
The serum of Atlantic sea lamprey, a basal vertebrate, contains two corticosteroids, 11-deoxycortisol and deoxycorticosterone.  Only 11-deoxycortisol has high affinity [Kd~3 nM] for the corticoid receptor [CR] in lamprey gill cytosol.  To investigate the binding of 11-deoxycortisol to the CR, we constructed 3D models of lamprey CR complexed with 11-deoxycortisol and deoxycorticosterone.  These 3D models reveal that Leu-220 and Met-299 in lamprey CR have contacts with the 17[alpha]-hydroxyl on 11-deoxycortisol.  Lamprey CR is the ancestor of the mineralocorticoid receptor [MR] and glucocorticoid receptor [GR].  Unlike human MR and human GR, the 3D model of lamprey CR finds a van der Waals contact between Cys-227 in helix 3 and Met-264 in helix 5.  Mutant...

5-HT1A autoreceptor modulation of locomotor activity induced by nitric oxide in the rat dorsal raphe nucleus
Provedor de dados: 56
Autores: Gualda,L.B.; Martins,G.G.; Müller,B.; Guimarães,F.S.; Oliveira,R.M.W.
The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhibitors produces anxiolytic- and antidepressant-like effects in rats and also induces nonspecific interference with locomotor activity. We investigated the involvement of the 5-HT1A autoreceptor in the locomotor effects induced by NO in the DRN of male Wistar rats (280-310 g, N = 9-10 per group). The NO donor 3-morpholinosylnomine hydrochloride (SIN-1, 150, and 300 nmol) and the NO scavenger...

A 4D-variational approach applied to an eddy-permitting North Atlantic configuration: Synthetic and real data assimilation of altimeter observations
Provedor de dados: 5
Autores: Ferron, Bruno.
The increasing number of oceanic observations calls for the use of synthetic methods to provide consistent analyses of the oceanic variability that will support a better understanding of the underlying mechanisms. In this study, a 1/3 degrees eddy-permitting model of the North Atlantic (from 20 degrees S to 70 degrees N) is combined with a 4D-variational method to estimate the oceanic state from altimeter observations. This resolution allows a better extraction of the physical content of altimeter data since the model spatial scales are more consistent with the data than coarser assimilation exercises because of a lower error in model representativity. Several strategies for the assimilation window are tested through twin experiments carried out under the...

A Bayesian Belief Network to Infer Incentive Mechanisms to Reduce Antibiotic Use in Livestock Production
Provedor de dados: 31
Autores: Ge,   Lan; Van Asseldonk,   Marcel A.P.M.; Valeeva,   Natasha I.; Hennen,   Wil; Bergevoet,   Ron H.M.
Efficient policy intervention to reduce antibiotic use in livestock production requires knowledge about the rationale underlying antibiotic usage. Animal health status and management quality are considered the two most important factors that influence farmers’ decision-making concerning antibiotic use. Information on these two factors is therefore crucial in designing incentive mechanisms. In this paper, a Bayesian belief network (BBN) is built to represent the knowledge on how these factors can directly and indirectly determine antibiotic use and the possible impact on economic incentives. Since both factors are not directly observable (i.e. latent), they are inferred from measurable variables (i.e. manifest variables) which are influenced by these...

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

A Better Approach to Resolving Variable Selection Uncertainty in Meta Analysis for Benefits Transfer
Provedor de dados: 31
Autores: Randall,   Alan; Chen,   Ding-Rong.
Because original high-quality non-market valuation studies can be expensive, perhaps prohibitively so, benefits transfer (BT) approaches are often used for valuing, e.g., the outputs of multifunctional agriculture. Here we focus on the use of BT functions, a preferred method, and address an under-appreciated problem – variable selection uncertainty – and demonstrate a conceptually superior method of resolving it. We show that the standard method of value-function BT, using the full estimated model, may generate BT values that are too sensitive to insignificant variables, whereas models reduced by backward elimination of insignificant variables pay no attention to insignificant variables that may in fact have some influence on values. Rather than searching...

A Biomimetic Model of the Outer Plexiform Layer by Incorporating Memristive Devices
Provedor de dados: 17
Autores: Andras Gelencser; Themistoklis Prodromakis; Christofer Toumazou; Tamas Roska.
In this paper we present a biorealistic model for the first part of the early vision processing by incorporating memristive nanodevices. The architecture of the proposed network is based on the organisation and functioning of the outer plexiform layer (OPL) in the vertebrate retina. We demonstrate that memristive devices are indeed a valuable building block for neuromorphic architectures, as their highly non-linear and adaptive response could be exploited for establishing ultra-dense networks with similar dynamics to their biological counterparts. We particularly show that hexagonal memristive grids can be employed for faithfully emulating the smoothing-effect occurring at the OPL for enhancing the dynamic range of the system. In addition, we employ a...

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

Autores: Fanganiello,R.D.; Kimonis,V.E.; Côrte,C.C.; Nitrini,R.; Passos-Bueno,M.R.
Inclusion body myopathy associated with Paget disease and frontotemporal dementia (IBMPFD) is a progressive and usually misdiagnosed autosomal dominant disorder. It is clinically characterized by a triad of features: proximal and distal myopathy, early onset Paget disease of bone (PDB), and frontotemporal dementia (FTD). It is caused by missense mutations in the valosin-containing protein (VCP) gene. We describe here the clinical and molecular findings of the first Brazilian family identified with IBMPFD. Progressive myopathy affecting the limb girdles was detected by clinical examination followed by muscle biopsy and creatine kinase measurement. PDB was suggested after anatomopathological bone examination and FTD was diagnosed by clinical,...

A Calibrate Auction-conjoint Experiment to Elicit Consumer Valuation of Sustainable Farming: Is Agro-systems Preservation Relevant?
Provedor de dados: 31
Autores: Avitia,   Jessica; Costa-Font,   Montserrat; Gil,   Jose Maria; Lusk,   Jayson L.
This paper analyses the role of agro-systems preservation on making food choices. It employs the “Calibrate Auction-Conjoint Valuation method” (CACM), which relates hypothetical conjoint valuation of product attributes with real market behavior using real economic incentives. The paper also allows comparing the hypothetical and nonhypothetical valuations in order to value the difference between the theoretic and the incentive-compatible WTP for a same respondent and within a single experiment. Thus the paper aims at testing for: 1) the internal consistency on people’s behavior towards sustainable agriculture, and 2) the relevance of the price attribute versus agro-ecosystems preservation for a fresh product. Results suggest that Spanish respondents’...

A canonical correlation analysis of the association between carcass and ham traits in pigs used to produce dry-cured ham
Provedor de dados: 74
Autores: Ventura,Henrique T.; Lopes,Paulo S.; Peloso,José V.; Guimarães,Simone E.F.; Carneiro,Antonio Policarpo S.; Carneiro,Paulo L.S.
The association between carcass and ham traits in a pig population used to produce dry-cured ham was studied using canonical correlation analysis. The carcass traits examined were hot carcass weight (HCW), backfat thickness (BT) and loin depth (LD), and the ham traits studied were gross ham weight (GHW), trimmed ham weight (THW), ham inner layer fat thickness (HIFT), ham outer layer fat thickness (HOFT), pH (pH) and the Göfo value. Carcass and ham traits are not independent.

A case of leucism in the burrowing owl Athene cunicularia (Aves: Strigiformes) with confirmation of species identity using cytogenetic analysis
Provedor de dados: 103
Autores: Nogueira,Denise M; Alves,Maria Alice S.
Leucism is an inherited disorder, characterized by the lack of pigments in part or all of the body, normal coloration of the eyes and, in birds, in naked parts such as the bill and legs. This kind of disorder is sometimes erroneously designated as albinism or partial albinism. In this study, we present a case of leucism in a wild owl. The studied individual presented completely white plumage, light-yellow coloration of legs and bill and normal coloration of eyes. According to morphological features, this owl is a specimen of burrowing owl, Athene cunicularia (Molina, 1782). To confirm the species identity, we used cytogenetic analyses for karyotypic determination, comparing it to the previously described one in the literature. We also studied a captive...

A Classic Case of Annular Pancreas and its Clinical Implications
Provedor de dados: 77
Autores: Nayak B,Satheesha; Mun Yooi,Ooi.
Annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. This may cause the duodenal constriction, obstruction, peptic ulcers and other complications. We saw a classic case of annular pancreas. The head of pancreas surrounded the second part of duodenum completely. However there was no narrowing of the duodenum. The case may be of importance for gastroenterologists, surgeons and radiologists.

A closer look at the role of the fruit and vegetable planting restriction provision on land use in the United States
Provedor de dados: 31
Autores: Lei,   Lei; Rickard,   Bradley J.; Balagtas,   Joseph Valdes; Krissoff,   Barry.
Current U.S. farm programs make payments to farmers based in part on historical base acres planted in particular program crops such as corn, soybeans, cotton, wheat and soybeans. Eligibility for payments includes regulations on the crops allowed to be grown on base acres, and there are restrictions on planting horticultural crops on such base acres. The fruits and planting restriction on base acres has potentially influenced the number of acres planted to fruits and vegetables over the past two decades. This research carefully examines the effects of planting restrictions applied to vegetables and program crops, using county-level data in the United States in 1982, 1987, 1992 and 1997. The paper employs the difference-indifference (DiD) approach to...

A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil
Provedor de dados: 49
Autores: Gonçalves,Fábio Bertolini; Menezes,Márcia Santos de.
Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average...

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

A comparative genetic diversity assessment of industrial and household Brazilian cassava varieties using SSR markers
Provedor de dados: 53
Autores: Siqueira,Marcos Vinicius Bohrer Monteiro; Borges,Aline; Valle,Teresa Losada; Veasey,Elizabeth Ann.
This study was carried out in order to assess the genetic diversity of 20 cassava (Manihot esculenta Crantz) genotypes with high phenotypic performance using microsatellite markers. Two groups were considered for this study: eleven varieties for industrial uses and nine for household consumption. By using nine microsatellite primers, high polymorphism was identified in all the loci analyzed, with values reaching 100%. On average, 3.4 alleles per locus were found, with 0.371 the value estimated for the observed heterozygosity and 0.555 for gene diversity for the entire set of varieties. The genetic variability found in both varieties, cultivated on a large-scale in the South Center region of Brazil, is wide enough to allow the choice of divergent parental...

A comparative study of clinical manifestations, haematological and serological responses after experimental infection with Anaplasma phagocytophilum in two Norwegian sheep breeds
Provedor de dados: 21
Autores: Stuen, Snorre; Grøva, Lise; Granquist, Erik G; Sandstedt, Karin; Olesen, Ingrid; Steinshamn, Håvard.
Background: It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called  Norwegian Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against  tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The  aim of the present study was to test this hypothesis in an experimental infection study.  Methods: Five-months-old lambs of two Norwegian sheep breeds, Norwegian White (NW) sheep and Old Norse  (ON) sheep, were experimentally infected with a 16S rRNA genetic variant of Anaplasma phagocytophilum (similar  to GenBank accession number M73220). The experiment was repeated for two subsequent years, 2008 and 2009,  with the use of 16...

A comparative study on the production of ethanol from lignocellulosic biomass by chemical and biological method
Provedor de dados: 17
Autores: Shaheed SM; Rohit JP; Madhan R; Selvakumar K.
Ethanol derived from non-edible biomass is renewable and a clean source of energy. It is independent of the food industry and it is economically feasible. The first generation biofuel or bioethanol is still not a very convenient source of energy as it prominently depends on the availability of grains. The main objective of this work is to develop an industrious efficient process to produce ethanol from lignocellulosic biomasses like wood and leaf in a lab scale. Two processes were compared. The first process involved an alkaline pre-treatment of the powdered biomass followed by dilute acid hydrolysis. The second process involved an alkaline treatment followed by direct hydrolysis of the biomass by use of a fungal species obtained from rotting wood....

A comparison between Joint Regression Analysis and the Additive Main and Multiplicative Interaction model: the robustness with increasing amounts of missing data
Provedor de dados: 63
Autores: Rodrigues,Paulo Canas; Pereira,Dulce Gamito Santinhos; Mexia,João Tiago.
This paper joins the main properties of joint regression analysis (JRA), a model based on the Finlay-Wilkinson regression to analyse multi-environment trials, and of the additive main effects and multiplicative interaction (AMMI) model. The study compares JRA and AMMI with particular focus on robustness with increasing amounts of randomly selected missing data. The application is made using a data set from a breeding program of durum wheat (Triticum turgidum L., Durum Group) conducted in Portugal. The results of the two models result in similar dominant cultivars (JRA) and winner of mega-environments (AMMI) for the same environments. However, JRA had more stable results with the increase in the incidence rates of missing values.

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

A Comparison of Auction and Choice Experiment: An Application to Consumer Willingness to Pay for Rice with Improved Storage Management
Provedor de dados: 31
Autores: Su,   Lianfan; Adam,   Brian D.; Lusk,   Jayson L.; Arthur,   Frank.
Experimental auction and discrete choice experiment are two popular value elicitation methods. Theoretically they should yield the same results but empirical results have been mixed (e.g., Lusk and Schroeder 2004, 2006; Corrigan et al. 2010.) This study uses both methods to determine consumers’ willingness to pay (WTP) for rice with improved insect control and for rice stored using Integrated Pest Management (IPM). This study investigates two potential reasons – anchoring and information – for why some studies have found apparent inconsistencies between auction and choice experiment results. Results indicate that consumers’ WTP derived in the auction and choice experiments are significantly different. Consumers’ average bids in the auction are higher than...

Both Indonesia and Vietnam, as members of ASEAN, have negotiated a free trade agreement with China (ACFTA). ASEAN Member States can independently negotiate their tariff reductions. Both countries are generally aware of the opportunities access to the large Chinese market may present, but both are concerned to differing degrees about being flooded with Chinese imports, including agricultural products. As the time for implementation approaches, Indonesia has expressed a desire to renegotiate its tariff reduction schedules to protect sensitive sectors, including agriculture. By contrast, Vietnam, just over the border from China and with a history of informal trade, seems more accepting of the prospects. A global general equilibrium model, GTAP, is used to...

A comparison of paraffin and resin-based techniques used in bark anatomy
Provedor de dados: 16
Autores: Hamann, T.; Smets, E.; Lens, F.
Bark anatomy is an unappreciated discipline in plant systematics, despite its great potential to reveal systematically informative features. In this paper, main reasons for the lack of detailed bark anatomical data in many plant families are identified, including problems with sectioning, terminological issues, and difficulties in observation of dilated stems. We deal with these problems by focusing on two aspects: (1) compare, discuss and improve existing sectioning and maceration techniques using two species with soft and hard bark tissues; and (2) discuss the best way to collect stem bark samples. We hope that this paper will stimulate inclusion of bark anatomical data in future systematic studies.

A comparison of soil and water properties in organic and conventional farming systems in England
Provedor de dados: 21
Autores: Hathaway-Jenkins, L. J.; Sakrabani, R; Pearce, Bruce; Whitmore, A. P; Godwin, R. J.
Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields. The physical soil properties varied...

A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements
Provedor de dados: 31
Autores: Argiles,   Josep M.; Brown,   Nestor Duch.
While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming...

A Comparison of the Great Mississippi River Floods of 1993 and 2011: Implications for Crop Insurance and Reinsurance
Provedor de dados: 31
Autores: Vergara,   Oscar.
The flooding situation in 2011 is similar in nature to the Great Mississippi Flood of 1993, but different in the particulars. First, the timing of the flood within the growing season is different. Second, the two floods occurred in different regions, with the 1993 flood affecting a portion of the Corn Belt and the 2011 flood affecting a region farther south. While floodwaters have inundated several million acres of cropland in 2011, yield losses from delayed planting are expected to be limited. Furthermore, the affected states from the current flood are primarily Group 2 states under the current SRA, which are provided with greater reinsurance protection by the government than the Group 1 states.

Variations in the branches of the abdominal aorta were determined during a routine abdominal region dissection of a 70-year-old male cadaver. Left gastric artery arose as the first root from antero-lateral of aorta. Coeliacomesenteric trunk occurred as a thick root. After 29.9mm, coeliacomesenteric trunk bifurcated as coeliac trunk and superior mesenteric artery. Coeliac trunk bifurcated as splenic artery and common hepatic artery. These multiple variations which change the normal anatomic structure of the abdominal aorta have to be kept in mind by surgeons, radiologists and anatomists.

A Composite Fuzzy Indicator for Assessing Farm Household Potential for Non-farm Income Diversification
Provedor de dados: 31
Autores: Fritzsch,   Jana.
European politicians encourage the income diversification of rural households through various measures. Although being aware of farm households’ potential for non-farm income diversification seems important for finely-targeting such policy measures, no attempt has thus far been made to summarise the various determinants of income diversification in a single figure. This contribution aims to close this gap. A composite fuzzy indicator that measures farm household potential for non-farm income diversification is developed and applied to 1,053 farm households in Bulgaria, Hungary, Poland, Romania, and Slovenia. The indicator summarises the incentives of and capacities for non-farm income diversification on the individual household member level, and on the...

Autores: Martinez Soto,   Moises E.; Monroy,   Carlos Rodriguez; Fuentes-Pila,   Joaquin; Morris Diaz,   Anne; Araujo,   M. Gil.
System dynamics is an appropriate tool to build management models due to its ease of application in solving unstructured problems. In the twenty-first century the sustainability of organizations is influenced by the way it manages its knowledge. In this sense, knowledge management (KM) represents a strategy that contributes to improving the production supply chain (SC) of the agri-food industry (AFI). The objective of this research is to develop a computer model to simulate the effect of KM on the production of AFI. The methodology applied was that of the system dynamics by using the Vensim PLE ® v. 5.10 software, whose determining indicators were selected through an empirical study of KM in the SC of precooked corn flour industry in Venezuela.

Autores: Sanches, Cinara Del´ Arco.
O Brasil, apesar dos avanços no que diz respeito à agricultura familiar, permanece sob a orientação de políticas governamentais que reforçam o apoio ao setor agroindustrial e ao agronegócio orientado à exportação com ênfase nas monoculturas dependentes de agroquímicos. No contexto atual de crise do modelo hegemônico de produção e consumo de alimentos, a Agroecologia emerge como proposta científica e delineia um conjunto de ações e estratégias que fundamentam o novo paradigma de desenvolvimento rural, demandado especialmente pelo segmento da agricultura familiar. Percebe-se que o enfrentamento desse modelo ocorre em um campo de disputa na sociedade que é antes de tudo político. Destarte, o adensamento territorial das experiências agroecológicas permite...

A coupled climate model simulation of Marine Isotope Stage 3 stadial climate
Provedor de dados: 5
Autores: Brandefelt, J.; Kjellstrom, E.; Naslund, J. -o.; Strandberg, G.; Voelker, A. H. L.; Wohlfarth, B.
We present a coupled global climate model (CGCM) simulation, integrated for 1500 yr to quasi-equilibrium, of a stadial (cold period) within Marine Isotope Stage 3 (MIS 3). The simulated Greenland stadial 12 (GS12; similar to 44 ka BP) annual global mean surface temperature (T-s) is 5.5 degrees C lower than in the simulated recent past (RP) climate and 1.3 degrees C higher than in the simulated Last Glacial Maximum (LGM; 21 ka BP) climate. The simulated GS12 is evaluated against proxy data and previous modelling studies of MIS3 stadial climate. We show that the simulated MIS 3 climate, and hence conclusions drawn regarding the dynamics of this climate, is highly model-dependent. The main findings are: (i) Proxy sea surface temperatures (SSTs) are higher...

A crise econômica mundial de 2007 a 2009 e o setor exportador de café no Brasil: análise das perdas
Provedor de dados: 31
Autores: Pereira,   Vanessa da Fonseca; Campos,   Antonio Carvalho; Braga,   Marcelo Jose; Mendonca,   Talles Girardi de.
This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...

This paper presents a conceptual tool, or heuristic, for describing the epistemological context for social learning within complex social&amp;#8211;ecological systems. The heuristic integrates several definitions of social learning that emphasize the importance of critical reflection and its collaborative nature and that it is rooted in and oriented toward practice through social interactions. The conceptual tool is useful in identifying and conceptually mapping different perspectives based on types of learning described along three dimensions: typology of knowledge; different levels of critical reflection; and scale. The heuristic was originally developed in the context of an environmental planning process in southern Ontario, Canada, and is applied to...

A Cultura do Taro - Inhame (Colocasia esculenta (L.) Schott): Alternativa para o Estado de Roraima.
Provedor de dados: 14
Autores: SILVA, E. E. da.
O taro, também conhecido como inhame no centro-sul do Brasil, ocorre de forma selvagem na Ásia tropical se estendendo até o leste da Nova Guiné e provavelmente norte da Austrália. Acredita-se que o Taro foi domesticado no norte da Índia e Nova Guiné antes mesmo do arroz. Foi disseminado para China, Arábia e o leste do Egito há cerca de 2000 anos atrás (CEAGESP, 2002), tornando-se a cultura mais importante economicamente e culturalmente. De lá o taro foi levado pelos árabes para a África Ocidental. Foi levado da Espanha ao Novo Mundo e pode ter sido novamente introduzido na África Ocidental advindo da América tropical (PLUCKNETT, 1983; PUIATTI, 2001). Agora, o taro é cultivado em muitas partes dos trópicos e subtrópicos. Na África, a importância do taro...

A decline in pollinator dependent vegetable crop productivity in India indicates pollination limitation and consequent agro-economic crises.
Provedor de dados: 17
Autores: Parthiba Basu; Ritam Bhattacharya; Pietro Ianetta.
Approximately 70% of the tropical crop species depend on pollinators for optimum yields (Roubik, 1995, Klein 2007). The economic value of such pollinated crops to India is $726 million and India is the world&amp;#x27;s second largest vegetable producer (Sidhu, 2005). This status has been underpinned by large-scale changes in land-use and pesticide dependency (Fazal, 2000; Shaw &amp;#x26; Satish, 2007). A method (c.f. Aizen et al. 2008) that partitions crops into categories depending on their relative pollinator dependence (Index of pollinator dependence, DI) was applied to analysis of vegetable yields for India over 45 years (1963-2008) using FAO data. This has revealed that since 1993, relative yields of crop production has either flattened or declined,...

Com o crescente desenvolvimento de tecnologias voltadas para a agricultura, são evidentes os incrementos na utilização de insumos, em especial de pesticidas. O uso de agroquímicos vem contribuindo para o aumento da produtividade agrícola, mas também tem sido responsável por efeitos adversos sobre o meio ambiente e a saúde humana. Atualmente, com o avanço da agricultura de base agroecológica, novas medidas de proteção de plantas vêm apresentando destaque, como a indução de resistência, que é ativação  de mecanismos de defesa vegetal para o controle de pragas e doenças. Um enorme volume de pesquisas dentro da fitopatologia se concentra no fenômeno da especificidade entre o patógeno e o hospedeiro, fenômeno de reconhecimento, do papel das fitotoxinas e...

A dinâmica florestal no pólo agropecuário do nordeste paulista
Provedor de dados: 14
Autores: ARAUJO, L. S. de; GREGO, C. R.; BOLFE, E. L.; OSHIRO, O. T.
No contexto do histórico de uso e ocupação das terras do Estado de São Paulo, que resultou na perda quase total de suas florestas originais e degradação dos remanescentes, as atividades agropecuárias são identificadas como potenciais condicionantes pela crescente expansão ocorrida nas últimas décadas. Por outro lado, levantamentos atuais, como o realizado pelo Instituto Florestal de São Paulo, demonstram um incremento na área mapeada como vegetação nativa do Estado (ZORZETTO, 2010), com curva ascendente similar às formulações recentes da Teoria da Transição Florestal (RUDEL, 1998; RUDEL et al., 2005). De acordo com essa Teoria, os estoques florestais mudam de modo previsível, com o decréscimo da taxa de desflorestamento e aumento da taxa de regeneração...

A Draft Sequence of the Puerto Rican Parrot Genome (Amazona vittata) &amp;#x2013; a Genome Project funded by a Local Community Effort
Provedor de dados: 17
Autores: Taras K. Oleksyk.
The genome of the Puerto Rican parrot (Amazona vittata) has been sequenced and assembled in an international collaboration supported by many individual donations from the people of Puerto Rico.  This is a critically endangered endemic bird, the only surviving native parrot species in the territory of the United States, and the first parrot belonging to the large genus Amazona to have its genome sequenced and assembled.  A genome of one A. vittata female was sequenced resulting in a total of almost 42.5 billion nucleotide bases equivalent to 26.89X average coverage depth. After filtering out the short fragments (&amp;#x3c;500bp), the assembly resulted in 259,423 short fragment library contigs, half of them (N50) of at least 6,983 bp in length, with a...

A Dual Response Choice Experiments (DRCE) design to assess rabbit meat preference in Catalonia: A Heteroescedatistic Extreme-Value Model
Provedor de dados: 31
Autores: Kallas,   Zein; Maria Gil,   Jose.
Our paper analyzes consumer preferences toward fresh rabbit meat and alternative marketing formats for rabbit meat. The empirical analysis uses consumer-level questionnaires to elicit information regarding consumer attitudes toward rabbit meat in Catalonia (Spain). We use the Dual Response Choice Experiment (DRCE) design which allows for analyzing forced and unforced options in choice experiments using the same sample. The Heteroscedastic Extreme- Value (HEV) model is used due to its relaxation of the restrictive assumption made in the Multinomial Logit Model regarding the identically distributed error term across alternatives. Our results demonstrate a higher preference for rabbit meat from “Catalan” origin followed by higher quality certification...

A Dynamic Adoption Model with Bayesian Learning: Application to the U.S. Soybean Market
Provedor de dados: 31
Autores: Ma,   Xingliang; Shi,   Guanming.
Agricultural technology adoption is often a sequential process. Farmers may adopt a new technology in part of their land first and then adjust in later years based on what they learn from the earlier partial adoption. This paper presents a dynamic adoption model with Bayesian learning, in which forward-looking farmers learn from their own experience and from their neighbors about the new technology. The model is compared to that of a myopic model, in which farmers only maximize their current benefits. We apply the analysis to a sample of U.S. soybean farmers from year 2000 to 2004 to examine their adoption pattern of a newly developed genetically modified (GM) seed technology. We show that the myopic model predicts lower adoption rates in early years than...

A DYNAMIC GENERAL EQUILIBRIUM ANALYSIS OF U.S. BIOFUELS PRODUCTION
Provedor de dados: 31
Autores: Beach,   Robert H.; Birur,   Dileep K.; Davis,   Lauren M.; Ross,   Martin T.
With the rising global interest in energy security and climate change mitigation, biofuels have gained the prominent attention of researchers and policy makers. The U.S. has emerged as the leading producer of biofuels and is aiming for achieving a target of 36 billion gallons of renewable fuels by 2022 under its updated renewable fuels standard (RFS2) policy. In this paper, we study the longer-term global implications of large-scale renewable fuels production in the U.S. We utilize the GTAP v7.1 data base and introduce a detailed breakdown of agricultural crops, first and second generation biofuels and by-products. We update this fully disaggregated data base to reflect the 2010 global economy, based on secondary data for the sectors and regions included....

A Dynamic Optimal Crop Rotation Model in Acreage Response
Provedor de dados: 31
Autores: Cai,   Ruohong; Bergstrom,   John C.; Mullen,   Jeffrey D.; Wetzstein,   Michael E.
This paper presents a dynamic crop rotation model that shows how crop yield and price volatility could impact crop mix and acreage response under crop rotation considerations. Specifically, a discrete Markov decision model is utilized to optimize producers’ crop rotation decision within a finite horizon. By maximizing net present value of expected current and future profits, a modified Bellman equation helps develop optimum planting decisions. This model is capable of simulating crop rotations with different lengths and structures. Specifically, the corn-soybeans rotations were simulated using the crop rotation model.

Autores: HOFFMANN, A.; NAVES, R. de L.
Quando falamos sobre a vitivinicultura nacional, é impossível não lembrar de regiões tradicionais de cultivo, como é o caso em especial da Serra Gaúcha. Esta ainda permanece como a principal região produtora de uvas para processamento no Brasil, onde também está localizada a sede da Embrapa Uva e Vinho. Mas a expansão deste "Brasil vitivinícola" requer que nossa atuação aconteça em todo o Brasil. Assim, para dinamizar a pesquisa desde 1993 a Unidade conta com uma estrutura física de apoio atualmente denominada Estação Experimental de Viticultura Tropical, em Jales, localizada no noroeste paulista. A Estação foi criada a partir da demanda do setor produtivo vitícola da região e viabilizada com o apoio da Prefeitura Municipal de Jales, o Ministério da...

Autores: Nemeth-T.,   Anett; Vincze-Tóth,   Judit; Trojan,   Szabolcs.
A magyar hűtőipar számára a külföldi piacokon való értékesítés nagy jelentőségű. A hűtőipar talán az egyetlen ágazat, melynek termelése minőségileg sosem különült el az értékesítés piacai szerint, köszönhetően annak, hogy a vertikumban a nemzetközi követelmények érvényesültek. A komplex vásárlói modellek elemzését követően megállapítható, hogy az ízesített termékeket leginkább az aktív szellemi foglalkozásúak részesítik előnyben, akik átlag feletti jövedelemmel rendelkeznek. Az ízesített termékek és a vegyes összetevőjű (mix) termékek tipikus vásárlója között nem tapasztalható jelentős eltérés. A vizsgálat eredményei alapján az a következtetés vonható le, hogy az egy összetevőjű termékek vásárlói között a legalacsonyabb a férfiak és a legmagasabb a nők,...

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

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

A few remarks on the relationship between visuo-spatial attention deficits and dyslexia
Provedor de dados: 17
Autores: John Skoyles; Bernt C. Skottun.
Dyslexia and attentional problems are often comorbid. This raises the question whether reading deficits might etiologically follow from attentional difficulties, a hypothesis that has been proposed in regard to visuo-spatial attention deficits. This visuo-spatial attention deficit hypothesis would  predict that attention deficits should be specific to dyslexia. However, it is here estimated that at the population level there are more non-dyslexic individuals than dyslexic individuals with visuo-spatial attention deficits. The reason for this is that in the overall population level there are far more individuals without dyslexia than with dyslexia. Thus, a relatively modest percentage presence of attention problems in the non-dyslexic population can result...

A financial analysis of the effect of the mix of crop and sheep enterprises on the risk profile of dryland farms in south-eastern Australia
Provedor de dados: 31
Autores: Hutchings,   Timothy R.; Nordblom,   Thomas L.
This study analyses the financial risk faced by representative mixed-enterprise farm businesses in four regions of south-eastern Australia. It uses discrete stochastic programming to optimise the ten-year cash flow margins produced by these farms operating three different farming systems. Monte Carlo analysis is used to produce a risk profile for each scenario, derived from multiple runs of this optimised model, randomised for commodity prices and decadal growing season rainfall since 1920. This analysis shows that the performance of the enterprise mixes at each site is characterised more by the level of variability of possible outcomes than by the mean values of financial outputs. It demonstrates that relying on mean values for climate and prices...

This preliminary study assessed genotype x diet interaction in late growth of European sea bass (Dicentrarchus labrax) fed with either a fish meal (FM)- or a fish oil (FO)-based diet (M) or an all-plant-based (PB) diet. A total of 550 fish from 224 families were reared together and tagged. DNA was sampled and microsatellites were used to assign parentage. When fish weight was 192 +/- 54 g, two tanks were fed with M (FM: 100%; FO: 100%) and two others with PB (FM: 0% and FO: 0%). Body weight (BW), fork length (FL) and fillet lipid content (CorrFat) were analysed with a linear model and with REML methodology. We observed no significant differences between groups, but a slightly lower (P=0.03) daily growth coefficient in sea bass fed PB than in those fed M....

A Free Trade between Ukraine and the European Union: Challenges and Opportunities for Agricultural Markets
Provedor de dados: 31
Autores: Nekhay,   Olexandr; Gay,   Stephan Hubertus; Fellmann,   Thomas.
The negotiations on a deep and comprehensive free trade agreement (FTA) between Ukraine and the EU are currently in process. Such a FTA can be expected to imply opportunities as well as challenges for agricultural markets. This paper provides a model-based quantitative assessment of the potential impacts of a FTA on agricultural commodity markets in the EU and Ukraine. For the quantitative analysis the dynamic, partial equilibrium model AGLINK-COSIMO has been adapted and applied. The modules for the EU and Ukraine have been extracted from the global model and prepared to run together. Thus, the focus is on the bilateral trade positions and not on the effect on other countries. The simulation of a FTA between the EU and Ukraine was done through the...

A Functional Study of Transforming Growth Factor-Beta from the Gonad of Pacific Oyster Crassostrea gigas
Provedor de dados: 5
Autores: Corporeau, Charlotte; Groisillier, Agnes; Jeudy, Alexandra; Barbeyron, Tristan; Fleury, Elodie; Fabioux, Caroline; Czjzek, Mirjam; Huvet, Arnaud.
The transforming growth factor (TGF)-beta superfamily is a group of important growth factors involved in multiple processes such as differentiation, cell proliferation, apoptosis and cellular growth. In the Pacific oyster Crassostrea gigas, the oyster gonadal (og) TGF-beta gene was recently characterized through genome-wide expression profiling of oyster lines selected to be resistant or susceptible to summer mortality. Og TGF-beta appeared specifically expressed in the gonad to reach a maximum when gonads are fully mature, which singularly contrasts with the pleiotropic roles commonly ascribed to most TGF-beta family members. The function of og TGF-beta protein in oysters is unknown, and defining its role remains challenging. In this study, we develop a...

The geophilomorph centipede Pectiniunguis minutus (Demange, 1968), a little known dwarf schendylid from Gabon (Western equatorial Africa), is redescribed and illustrated based on the type material and an additional non-type specimen preserved in the collections of the Muséum national d'Histoire naturelle, Paris. P. minutus can be easily differentiated from all the other species currently assigned to the genus Pectiniunguis, by the very low number of leg-bearing segments (35 in the males, 37 or 39 in the females) and very small body size (12-16 mm in length). P. minutus is also distinguished by having ventral pore-fields on the anterior region of the body only, this character being shared by a single species of the genus, i.e., P. ascendens Pereira, Minelli...

A future for marine fisheries in Europe (Manifesto of the Association Francaise d'Halieumetrie)
Provedor de dados: 5
Autores: Gascuel, D.; Bez, Nicolas; Forest, Andre; Guillotreau, P.; Laloe, F.; Lobry, Jeremy; Mahevas, Stephanie; Mesnil, Benoit; Rivot, Etienne; Rochette, S.; Trenkel, Verena.
We, members of the Association Francaise d'Halieumetrie, share the conviction that European fisheries have a future. It is time to get off the wrong track. Radical change is required to embark on the path of sustainable development and truly implement the ecosystem approach to fisheries. Today, high fishing pressure is deployed to catch a rare resource, which in return is responsible for the rarity. We must reverse the situation: an abundant resource that affords high catches applying moderate fishing pressure. All management tools and especially all actors must be mobilized. The transition is not simple, and European solidarity must accompany the changes. It is well worth the effort. By reducing fishing pressure, it will be possible in the medium term to...

A G4MP2 theoretical study on the gas phase enthalpies of formation for various polycyclic aromatic hydrocarbons (PAHs) and other C~10~ through C~20~ unsaturated hydrocarbons
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
Gas phase enthalpies of formation at 298.15 and 1 atm (&amp;#x394;~f~H~(g),298K~) were calculated using the atomization approach at the G4MP2 composite method level of theory for 86 polyaromatic hydrocarbons (PAHs) and other C~10~ through C~20~ unsaturated hydrocarbons. Where available, good agreement with prior experimental data and/or high level theoretical estimates was obtained. Linear regressions between semiempirical MNDO, MNDO-d, AM1, PM3, RM1, and PM6 estimated &amp;#x394;~f~H~(g),298K~ and the corresponding G4MP2 values were employed to obtain G4MP2 corrected semiempirical &amp;#x394;~f~H~(g),298K~ for a suite of 156 C~11~ through C~42~ unsaturated hydrocarbons and PAHs.

A G4/W1BD theoretical study into the gas phase enthalpies of formation for potential high energy materials
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
Enthalpies of formation (&amp;#x394;~f~H~(g)~) at 298.15 K and 0 K were calculated for various potential high energy materials (HEMs) using the high-level Gaussian-4 (G4) and W1BD methods with the atomization approach. Where prior high level estimates are available in the literature, the G4 and W1BD &amp;#x394;~f~H~(g)~ are in good agreement. The results presented herein represent the highest level calculations performed to date on this suite of HEMs. These G4/W1BD enthalpies of formation should provide utility among the research community as a benchmark set of values against which to assess future experimental and/or theoretical data.

Autores: Szekely,   Erika.
A magyarországi gazdálkodók az EU 27 tagállama közötti képzettségi rangsorban a 19. helyet foglalják el. Ezért rendkívül fontos a tanácsadás igénybevételének szorgalmazása. A gazdálkodók leginkább a falugazdász hálózat és az alapanyag forgalmazók képviselőivel tartanak kapcsolatot, jórészt az adminisztratív tennivalók miatt. A termelési-technológiai tanácsadást gyakorlatilag az inputanyag-forgalmazók látják el, ami erős konkurenciát jelent a névjegyzéki szaktanácsadásnak. A szaktanácsadási rendszer szereplőinek elsődleges feladata a tanácsadás piaci keresletének bővítése.------------------------------------------------------- By European comparison the professional expertise of Hungarian agricultural producers can be considered poor, although not among the...

A general framework for indicator design and use with application to the assessment of coastal water quality and marine protected area management
Provedor de dados: 5
Autores: Beliaeff, Benoit; Pelletier, Dominique.
Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of management-oriented indicators, integrating management questions and performance criteria. We first examined the desirable characteristics of indicators aimed at providing decision-support for marine environmental management. Ideally, one should select the indicator that guarantees a safe and unambiguous decision leading to the appropriate measures in terms of regulation, remediation or control. In the present study, indicators are assessed according to two criteria: relevance and effectiveness. Relevance...

A global comparison of Argo and satellite altimetry observations
Provedor de dados: 5
Autores: Dhomps, A. -l.; Guinehut, S.; Le Traon, Pierre-yves; Larnicol, Gilles.
Differences, similarities and complementarities between Sea Level Anomalies (SLA) deduced from altimeter measurements and dynamic height anomalies (DHA) calculated from Argo in situ temperature (T) and salinity (S) profiles are globally analyzed. SLA and DHA agree remarkably well and, compared to previous studies, Argo dataset allows an improvement in the coherence between SLA and DHA. Indeed, Argo data provides a much better spatial coverage of all oceans and particularly the Southern Ocean, the use of an Argo mean dynamic height, the use of measured salinity profiles (versus climatological salinity), and the use of a deeper reference level (1000 m versus 700 m). The large influence of Argo salinity observations on the consistency between altimetry and...

A Good Opening: The Key to Make the Most of Unilateral Climate Action
Provedor de dados: 31
Autores: Bosetti,   Valentina; De Cian,   Enrica.
In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the benefits of cooperation, the incentive to expand the demand of fossil fuels, and the incentive to adopt cleaner technologies introduced by the coalition. Using an Integrated Assessment Model with a game theoretic structure we find that cost-benefit considerations would lead OECD countries to undertake a moderate, but increasing abatement effort (in line with the pledges subscribed in Copenhagen). Even if emission reductions are moderate, OECD countries find it optimal to allocate part of their resources to energy...

A HAZARD ANALYSIS OF CONSUMERS’ SWITCHING BEHAVIOUR IN GERMAN FOOD RETAILING FOR DAIRY PRODUCTS
Provedor de dados: 31
Autores: Olearius,   Gotz; Roosen,   Jutta; Drescher,   Larissa S.
German food retailing is characterized by fierce competition among retail chains for consumer shopping. This paper considers the switching behaviour using data of white dairy product purchases. The empirical investigation uses a survival analysis approach, in particular hazard analysis. The results extend the knowledge of shopping behaviour by providing a new set of explaining variables and the importance of the first store, defined as store with the major share of household budget, becomes apparent. On average, households buy dairy products 42 times per year. Thereof 58 % are retail chain switches and in 41 % of all cases the households remain at the previously visited retail chain. Generally a low customer loyalty is visible in this investigation. It is...

A tanulmányban kérdőíves felmérésünk eredményeire támaszkodva bemutatjuk a 2007-ben megalakult LEADER HACS-ok fontosabb működési jellemzőit. Országos felmérésünkből kiderül, hogy nincsen hagyománya, gyakorlata a fejlesztésekben való együttműködésnek, holott a helyi program végrehajtása nagymértékben múlik a helyi társadalom felkészültségén, az emberek és szervezetek együttműködésén. A HACS-ok által lefedett térségek fejlődését több vonatkozásban a humán erőforrások, a vidéki emberek és közösségeik (az ún. szoft tényezők) hiányosságai gátolják, következésképpen sürgető a humán erőforrások fejlesztése is.

A heterogeneous-agent model with district-level constraints: an application to livestock development in Gansu, China
Provedor de dados: 31
Autores: Komarek,   Adam M.; Waldron,   Scott A.; Brown,   Colin G.
This paper develops a heterogeneous-agent model to assess the impacts of removing lucerne growing subsidies, increasing livestock numbers and including district-level equilibrium conditions on optimal farm plans in the Qingyang district of Gansu Province, China. The model is a five-year dynamic linear program that solves across 96 farm households whilst incorporating district-level constraints. The approach used allows us to observe seasonal variations in incomes, infer the distribution of a policy shock among households and highlight trade patterns at the district level. The results suggest that without lucerne growing subsidies the total area of lucerne grown by all modelled households falls by 18%. Increasing livestock numbers by 25% reduces net...

Both genetic background and diet have profound effects on plasma lipid profiles. We hypothesized that a high-carbohydrate (high-CHO) diet may affect the ratios of serum lipids and apolipoproteins (apo) differently in subjects with different genotypes of the SstI polymorphism in the apoCIII gene (APOC3). Fifty-six healthy university students (27 males and 29 females, 22.89 ± 1.80 years) were given a washout diet of 54% carbohydrate for 7 days, followed by a high-CHO diet of 70% carbohydrate for 6 days without total energy restriction. Serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apoB100, apoAI, and the APOC3 SstI polymorphism were analyzed. The ratios of serum...

Autores: Kozak,   Janos.
A világ májtermelésének növekedése azt jelzi, hogy e különleges termék fogyasztása iránti igény várhatóan hosszabb távon fennmarad. A termelés szerkezetében azonban átrendeződés várható az olcsóbb hízott kacsamáj javára. Ugyanakkor a libamáj a hízottmáj-termékcsoportban csúcsminőség marad. Magyarország, mivel Franciaország után a legnagyobb májtermelő ország, továbbra is mindkét termék előállításában érdekelt lesz. Hazánk már évtizedek óta a világ vezető libamájtermelő országa, de a jövőben új piaci versenytársak (pl. Kína) megjelenésére is számíthat a világ májkereskedelmében. Emellett más országok növekvő kacsamájtermelése is egyre nehezebbé teszi a magyarországi májtermékek külpiaci értékesítését. Mivel a jelenlegi gyakorlattól eltérő módon hízott májat...

A Hybrid Land Conversion Model Incorporating Multiple End Uses
Provedor de dados: 31
Autores: Kaza,   Nikhil; Towe,   Charles A.; Ye,   Xin.
The need for models that forecast land use change spans many disciplines and encompasses many approaches. Pattern-based models were the first in which projections of change at specific locations in actual landscapes could be predicted. In contrast, recent economic models have modeled the underlying behavioral process that produces land use change. This paper combines attributes from each approach into a hybrid model using a multiple discrete continuous extreme value formulation that allows for multiple conversion types, while also estimating the intensity of each type of conversion, which is an important but often overlooked dimension. We demonstrate the simulation routine, which successfully predicts a majority of growth by type, time, and location at a...

A hydrometric analysis of the Moose Jaw River near Burdick (05JE006): Temporal trends and frequency analyses for mean, minimum, and maximum flows
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
A hydrometric analysis over the available historical record (1973-2010) was conducted for the Moose Jaw River station near Burdick in south-central Saskatchewan, Canada. Frequency analyses on mean monthly, average annual, monthly minimum/maximum, and annual minimum flows generally yielded poor fits, and problems with negative flow predictions for mid- to long-term return periods regardless of distribution type. The annual maximum streamflow time series is reasonably well-described by linear and log Pearson Type III distributions, although both distribution types underestimate extreme maximum flows. Mann-Kendall linear time series analysis on mean monthly and annual streamflows reveals no trend in annual water yields, nor in mean monthly flows between March...

A impressionante agricultura irrigada no semiárido brasileiro.
Provedor de dados: 14
Autores: FREITAS, P. L. de.
São muitas as reflexões para explicar a natureza, ao colocar um rio caudaloso como o São Francisco em meio a uma região tão árida como a Caatinga. Certamente, um desafio para o ser humano mostrar a sua capacidade de aproveitar esta dádiva tão caudalosa e produzir alimentos e outros bens para o Brasil e o mundo. Essa provocação foi devidamente permeada entre os participantes do XXI Conird, tendo sido o Dia de Campo na ViniBrasil muito motivador.

A kereskedelmi márkák sikere a modern élelmiszer-ellátási lánc és a fogyasztói preferenciák formalizálódásának szimbóluma, ezen kívül a globális élelmiszer-kiskereskedelem egyre fontosabb hatalmi és versenyeszköze. A kereskedelmi márkás termékek részesedése ma már olyan jelentős a nemzetközi és hazai élelmiszerpiacon, hogy az ellátási lánc szinte minden szereplője számára érezhető és mélyreható változásokat hozott. Hatott a termékpályafázisok vertikális és horizontális piaci versenyére, a termékek árára és költségére, valamint jövedelmezőségére egyaránt. A választékot differenciáló, alacsonyabb fajlagos költséggel előállítható és alacsonyabb áron értékesíthető kereskedelmi márkák terjedésének elméleti előnye lehet, hogy az alacsonyabb fajlagos jövedelem...

Autores: Buday-Santha,   Attila.
A magyar mezőgazdaság és ezzel a magyar vidék elhúzódó válsága szinte kikényszeríti, hogy az egyes kormányprogramokban, nemzeti fejlesztési tervekben, területi gazdasági stratégiákban megváltó megoldásokat vonultassanak fel. Így kapott kiemelt figyelmet a vidéki turizmus, a kézműipar, a hungarikumok kérdése, jelenleg pedig a közvetlen termelői értékesítés lehetősége. Ezek közös jellemzője, hogy a kialakult állapotokat nem kérdőjelezik meg, csak annak életképességének javításához egy eddig is ismert megoldást tolnak előtérbe, elkerülve ezzel, hogy az alapvető gondokkal szembenézzenek. Nem esik szó a gazdasági versenyképességről, holott a folyamatosan végbemenő leépülési folyamat a versenyképesség elvesztésének egyenes következménye. Ez pedig az agrárágazat...

Autores: Hegedusne Baranyai,   Nora.
A vizsgálatok a rendszerváltozást követő időszakra vonatkozó piaci folyamatok – árak, felvásárolt mennyiségek – havi változásainak elemzésére irányultak. Célként fogalmazódott meg annak a hipotézisnek az igazolása, miszerint piacgazdasági körülmények között nem elhanyagolható rövid távú ciklikus ingadozásokkal szükséges számolni. A kukorica felvásárlási áránál öt teljes ciklus figyelhető meg az ár alakulásában 1992 januárja és 2011 januárja között. A ciklikus periódusok hossza 3-4 évre tehető. A vágósertésnél szintén öt ciklus rajzolódott ki a vizsgált időszakban. A hullámok hossza változó volt. A sertésáraknál a leghosszabbnak az utolsó előtti tekinthető, a maga három és fél évével.

A large scale study of trace metal contamination (Hg, Cd, Pb and Ni) by means of caged mussels Mytilus galloprovincialis was undertaken along the coastal waters of the Western Mediterranean Sea within the context of the MYTILOS project. Individual mussels from an homogeneous population (shell size 50 +/- 5 mm) obtained from an aquaculture farm were consecutively caged and deployed at 123 sites located in the Alboran, North-Western, South-Western and Tyrrhenian sub-basins for 12 weeks (April-July) in 2004, 2005 and 2006. After cage recoveries, both the metal content in the whole mussel tissue and the allometric parameters were measured. Statistical analysis of the datasets showed significant differences in concentrations between sub-basins for some metals...

A Lateralized Brain Network for Visuo-Spatial Attention
Provedor de dados: 17

Looking for a friend in the crowd, avoiding a sudden danger or contemplating a work of art are some examples of actions based on the efficiency of our visuo-spatial attention system. The specialization of the right brain hemisphere for visuo-spatial attention is a characteristic of most humans, but its anatomical basis remains largely unknown. Our study is the first to report in humans the existence of a bilateral parieto-frontal network whose hemispheric lateralization predicts the degree of specialization of the right hemisphere for visuo-spatial attention. Our results also suggest that this specialization is associated with an unbalanced speed of visuo-spatial processing between the two hemispheres. This lateralization may be predictive of visuo-spatial...

A link between sleep loss, glucose metabolism and adipokines
Provedor de dados: 56
Autores: Padilha,H.G.; Crispim,C.A.; Zimberg,I.Z.; De-Souza,D.A.; Waterhouse,J.; Tufik,S.; de-Mello,M.T.
The present review evaluates the role of sleep and its alteration in triggering problems of glucose metabolism and the possible involvement of adipokines in this process. A reduction in the amount of time spent sleeping has become an endemic condition in modern society, and a search of the current literature has found important associations between sleep loss and alterations of nutritional and metabolic contexts. Studies suggest that sleep loss is associated with problems in glucose metabolism and a higher risk for the development of insulin resistance and type 2 diabetes mellitus. The mechanism involved may be associated with the decreased efficacy of regulation of the hypothalamus-pituitary-adrenal axis by negative feedback mechanisms in...

A Macroanatomical and Histological Study of the Uropygial Gland in the White Stork (Ciconia cicionia)
Provedor de dados: 77
Autores: Kozlu,Tolunay; Bozkurt,Yesim Akaydin; Ates,Sevinc.
The present study was aimed at the macroanatomical and histological investigation and the demonstration of the structural characteristics of the uropygial gland in the white stork. The uropygial gland of two adult male white storks constituted the material of the study. It was determined that the gland was situated subcutaneously in between the caudal aspect of the lumbosacral bone and the first coccygeal vertebrae. The gland was composed of two lobes, which displayed an oval appearance when viewed from above and resembled a water drop when observed medially. Tuft of feathers were present on the caudal margin of each lobe. The present study revealed that the uropygial gland of the white stork is a simple tubular gland, which discharges its secretion into...

A magyar marhahús versenyesélyei az EU-ban
Provedor de dados: 31
Autores: Meszaros,   Kornelia; Beres,   Daniel.
A tanulmány a magyarországi vágásra szánt, élőszarvasmarha-külkereskedelem versenyképességét, komparatív előnyeit és hátrányait vizsgálja az 1999–2010 közötti időszakban. A marhahús jelentős része elsősorban exportra kerül. Vizsgálva ennek versenyképességét megállapítható, hogy jelenleg komparatív hátránya van az EU27-en belüli marhahúspiacon. A mutatók tendenciáját tekintve a hátrány mértéke évről évre csökkenő. Az RSCA-átlag mutatója a folyamatos emelkedést követően 2008-ban pozitív volt. A külkereskedelmi mérleg minden vizsgált évben aktív. A 2008-ban kibontakozott pénzügyi válság hatása ugyanakkor érződött, s jelentős visszaesést okozott, ami mindhárom mutató értékeiben megnyilvánult. A Gehlhar és Pick által kidolgozott kategóriák alapján pedig...

A magyarországi máktermelésről
Provedor de dados: 31
Autores: Karacsony,   Peter; Toth,   Kalman; Pinek,   Gyula; Pal,   Robert.
Hazánkban az utóbbi években egyre nagyobb területeken folyik alkaloida és étkezési mák termelése. Megállapítható, hogy nem igazolódtak be azok a várakozások, melyek az uniós csatlakozástól a máktermelés csökkenését várták, annak ellenére, hogy az unió korlátozta egyes hazai, magasabb alkaloidatartalmú fajták termelését. Vizsgálataink alapján megállapítható, hogy a máktermelés magas hektáronkénti termelési költsége ellenére jövedelmező. Ha a hazai máktermelést az 1960-as évek szintjére emelnék, akkor az hozzájárulhatna a napjainkban fennmaradásukért és mindennapi megélhetésükért küzdő – elsősorban a szegényebb kelet-magyarországi régiókban – gazdálkodók megélhetéséhez.   ------------------------------------- The area used for growing poppy seed for human...

A mezőgazdasági tanácsadás jelentős múltra tekint vissza hazánkban. Legfőbb célja, hogy a gazdáknak továbbított információk és ismeretek közvetítésével hozzájáruljon az eredményes gazdálkodáshoz, mert a gazdálkodók szakmai felkészültségében hiányosságok tapasztalhatók, jelentősek a különbségek az üzemméretekben, valamint az eredményekben. A hatékony szaktanácsadási rendszerrel szemben támasztott követelmények hazánkban csak részben teljesülnek, a jelenlegi struktúra számos területen beavatkozást igényel, így a szolgáltatók közötti feladatmegosztásban, a tanácsadók felkészültségében, a tanácsadási szolgáltatások iránti igényben, valamint a rendszer hatékonyságát illetően.

A marketing-finance approach linking contracts in agricultural channels to shareholder value
Provedor de dados: 31
Autores: Pennings,   Joost M.E.; Wansink,   Brian; Hoffmann,   Arvid O.I.
A conceptual marketing-finance framework is proposed which links channel contracting in agriculture and the use of financial facilitating services (e.g., financial derivatives) to (shareholder) value creation. The framework complements existing literature by explicitly including channel contract relationships as market-based assets that can be managed to reduce cash flow volatility and hence increase shareholder value. We show how financial facilitating services (e.g., derivatives) can be used to complement the cash flows components of channel contract relationships thereby further reducing the risk adjusted cost of capital and improving shareholder value. In a field study of producers, wholesalers, and processors, in the potato and meat industry the...

A Measure to Compare Matchings in Marriage Markets
Provedor de dados: 31
Autores: Biermann,   Florian M.
In matching markets the number of blocking pairs is often used as a criterion to compare matchings. We argue that this criterion is lacking an economic interpretation: In many circumstances it will neither reflect the expected extent of partner changes, nor will it capture the satisfaction of the players with the matching. As an alternative, we set up two principles which single out a particularly “disruptive” subcollection of blocking pairs. We propose to take the cardinality of that subset as a measure to compare matchings. This cardinality has an economic interpretation: the subset is a justified objection against the given matching according to a bargaining set characterization of the set of stable matchings. We prove multiple properties relevant for a...

To better understand the mechanism of excessive gas accumulation in the abomasum in bovine abomasal displacement, we performed gastric fluoroscopy in vagotomized cattle. Fifteen 6-month-old Holstein steers were divided into three groups: a non-vagotomized control group (Group C; n=5), a ventral thoraco-vagotomized group (Group V; n=5), and a dorsal and ventral thoraco-vagotomized group (Group DV; n=5). These groups were examined by fluoroscopy before and during a 5-week observation period after surgery. In Group C, no change was observed throughout the observation period. In Group DV, immediately after surgery, reticuloruminal motility was completely absent and ruminal distention was seen. Two weeks after surgery, abnormal reticulum motility and increased...

Ez arra készteti a jelen és a jövő kor társadalmát, hogy törekedjen a rendelkezésre álló megújuló energiaforrások felhasználásának előtérbe helyezésére, melyek használata a fenntarthatóság és a versenyképesség szempontjából sem elhanyagolható, hiszen ismert, hogy napjaink egyik kritikus költségtényezőjét adják az energiaköltségek. A megoldásban jelentős szerep hárul a vidéki társadalmakra, mert hiába történik az energiafelhasználás zöme az urbanizált területeken, az energia-előállítás, kitermelés a vidékre koncentrálódik. A fosszilis tüzelőanyagok korlátaiból adódóan új...

A megújuló és a fosszilis energiahordozók szerepe Magyarországon
Provedor de dados: 31
Autores: Magda,   Robert.
A magyar gazdaság energiaszükségletében meghatározóak a fosszilis eredetű tüzelőanyagok – kőolaj, földgáz, kőszén, illetve ezek származékai –, amelyek kimerülőben vannak, így növelik függőségünket, károsítják környezetünket. Ezért fokozott figyelmet kell fordítani az alternatív energiaforrásokra, amelyekről ma még az a véleményünk, hogy kimeríthetetlenek, kevésbé károsítják Földünket. A kutatók számára ma az jelent feladatot, hogy ezen erőforrások felhasználásának korlátait felkutassák, feltárják. Az előrelépés egyik tényezője a finanszírozásban keresendő, mert annak ellenére, hogy mintegy évtizede az aktuális kormányok folyamatosan hirdetik részarányuk növelésének szükségességét, a megfelelő – a társadalom nagy többsége számára elérhető – támogatási...

A metafrontier approach to measuring technical efficiencies across the UK dairy sector
Provedor de dados: 31
Autores: Barnes,   Andrew Peter; Revoredo-Giha,   Cesar; Sauer,   Johannes.
A regional approach is applied to measure technical efficiencies on dairy farms which employs the deterministic metafrontier approach. We construct six super regions for the UK, i.e. Eastern, Western, Northern England, Wales, Scotland and Northern Ireland. Data are collected through three different administrative systems, all be it under the same FADN guidance. We find for dairy farming comparative indicators of performance in all three data sets. The stochastic frontier approach is applied to construct 6 regional frontiers and a pooled (UK) dataset for comparison. A likelihood ratio test rejects the null hypothesis that these regions operate under a common frontier which may indicate bias in previous attempts to measure dairying efficiency at the country...

A minimum cross entropy model to generate disaggregated agricultural data at the local level
Provedor de dados: 31
Autores: Xavier,   Antonio; Martins,   Maria de Belem Costa Freitas; Fragoso,   Rui Manuel de Sousa.
This work presents an entropy approach to disaggregate agricultural data at a local level. It comprises two different steps. In a first one, an information prior at disaggregated level based on experts’ opinions, available cartography of land use and biophysical data is created. In a second step, it’s used a minimum cross entropy process in order to manage these information inputs and to guaranty a solution compatible with all the different restrictions. The model was applied to the region of Algarve in the year of 1999, in order to disaggregate the data at the pixel and county level. Results show that the model was able to provide some satisfactory results since the estimated values obtained for the different areas revealed a good approximation to the...

A Mixed Effects Model of Crop Yields for Purposes of Premium Determination
Provedor de dados: 31
Autores: Roberts,   Michael J.; Tack,   Jesse B.
Farm income is highly variable due to annual price and yield uncertainties. The federally subsidized crop insurance program is an important tool for managing this risk, and has grown from a relatively modest program to one that encompasses the majority of productive cropland in the country. The success of this program depends on identification of actuarially fair insurance premium rates, which in turn depends on accurate estimation of farm-level yield distributions. We use the confidential U.S. Department of Agriculture Risk Management Agency (RMA) panel dataset to estimate farm-specific distributions of yields and actually fair crop insurance premiums. Our ongoing work includes using the difference between our estimated actually fair premiums and RMA's to...

A model for evaluating beef cattle rations considering effects of ruminal fiber mass
Provedor de dados: 96
Autores: Henrique,Douglas Sampaio; Lana,Rogério de Paula; Vieira,Ricardo Augusto Mendonça; Fontes,Carlos Augusto de Alencar; Botelho,Mosar Faria.
A mathematical model based on Cornell Net Carbohydrate and Protein System (CNCPS) was developed and adapted in order to evaluate beef cattle rations at tropical climate conditions. The presented system differs from CNCPS in the modeling of insoluble particles' digestion and passage kinetics, which enabled the estimation of fiber mass in rumen and its effects on animal performance. The equations used to estimate metabolizable protein and net energy requirements for gain, net energy requirement for maintenance and total efficiency of metabolizable energy utilization were obtained from scientific articles published in Brazil. The parameters of the regression equations in these papers were estimated using data from Bos indicus purebred and crossbred animals...

A model for prediction of spatial farm structure
Provedor de dados: 31
Autores: Hoveid,   Oyvind; Stokstad,   Grete.
Spatial micro structure and its change over time is recorded for Norwegian farm firms. Relative strong correlations between geographically close neighbors are expected, either because growing farms swallow the smaller ones, or because they are affected by some spatially related unobserved factors. Strong correlations over time are also expected because of prevalent family farming. The paper proposes a state-of-the-art Markov chain model in order to predict the spatial and temporal micro structure taking account of both non-stationarity and spatio/temporal correlations by means of techniques from non-linear state space modeling and Gaussian Markov random fields. The model and the complete data set is then a device with which one can investigate the...

A Model of Labeling with Horizontal Differentiation and Cost Variability
Provedor de dados: 31
Autores: Saak,   Alexander E.
We study optimal disclosure of variety by a multi-product firm with random costs.  In our model there are two varieties that are horizontally differentiated and differ in overall quality, but buyers cannot distinguish between them without labels.  The equilibrium prices for labeled varieties are increasing functions of the absolute value of the cost differential and do not reveal which variety is cheaper to produce.  Nondisclosure is most common when there is moderate uncertainty about the relative input cost, not too much idiosyncrasy in consumer valuations, and not too much difference in quality across varieties.  Although mandatory disclosure of variety benefits consumers, it decreases expected welfare when relative input cost variability is large and...

A modelling study of beta-amyloid induced change in hippocampal theta rhythm
Provedor de dados: 17
Autores: Xin Zou; Damien Coyle; KongFatt Wong-Lin; Liam Maguire.
Many dementia cases, such as Alzheimer&amp;#x2019;s disease (AD), are characterized by an increase in low frequency field potential oscillations. However, a definitive understanding of the effects of the beta-Amyloid peptide, which is a main marker of AD, on the low frequency theta rhythm (4-7Hz) is still unavailable. In this work, we investigate the neural mechanisms associated with beta-Amyloid toxicity using a conductance-based neuronal network model of the hippocampus CA1 region. We simulate the effects of beta-Amyloid on the A-type fast inactivating K+ channel by modulating the maximum conductance of the current in pyramidal cells, denoted by gA. Our simulation results demonstrate that as gA decreases (through A[beta]&amp;#xd;&amp;#xa;blockage), the...

A modified Arcan test to analyze the behavior of composites and their assemblies under out-of-plane loadings
Provedor de dados: 5
Autores: Cognard, J. Y.; Sohier, L.; Davies, Peter.
Composite materials are a key element in weight reduction strategies, so the analysis of the mechanical behavior of assemblies of composite modules is of great importance. Failure initiation in bonded assemblies involving composites is often associated with crack initiation in the adhesive or delamination of the composite plies close to the adhesive joint, caused by interlaminar or through-thickness stresses. Thus, the analysis of the behavior of composites and their assemblies under out-of-plane loadings is necessary in order to optimize such structures. However, few experimental devices are proposed in the literature and they often require thick composite specimens which are not representative of most industrial applications. This paper describes the use...

A molecular method to detect and identify the native species of southwestern Atlantic Crassostrea (Mollusca: Ostreidae)
Provedor de dados: 103
Autores: Ludwig,Sandra; Patella,Raquel; Stoiev,Sérgio; Castilho-Westphal,Gisela; Girotto,Marcus V. F; Ostrensky,Antonio.
Among oysters, species of Crassostrea (Sacco, 1897) are the most attractive to aquaculture. In Brazil, the genus is represented by C. rhizophorae (Guilding, 1828) and C. brasiliana (Lamarck, 1819). Because the maturation and breeding technology is not well developed for these species, aquaculturists need a reliable method to decide the correct time to place spat collectors in the field, and to identify both species, which are morphologically similar. In this study a specific Multiplex PCR protocol was developed, using one pair of universal primers from 18S rDNA as a positive control and a pair of specific primers for each target species. The sensitivity and specificity of the protocol was evaluated. It detected C. rhizophorae DNA in low concentrations, and...

A molecularly based phylogeny reconstruction of mushroom corals (Scleractinia: Fungiidae) with taxonomic consequences and evolutionary implications for life history traits
Provedor de dados: 16
Autores: Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W.
The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I &amp; II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

Autores: Bomfim,ZV; Lima,KM; Silva,JG; Costa,MA; Zucchi,RA.
This study investigated the level of morphometric and genetic variability among populations of Anastrepha pickeli Lima from several localities in Brazil, one locality in Bolivia and one in Paraguay. Traditional and geometric morphometric analyses were used, as well as sequencing of a fragment of the cytochrome oxidase gene (COI). Six variables were measured from the aculeus for traditional morphometric analysis and 14 landmarks from the right wing were used for geometric analysis, using 10 specimes/population. The aculeus tip length, aculeus width at the end of the cloaca opening, and the serrate part length contributed with 62.7% for grouping. According to the results from traditional morphometry, there was no significant difference, but the multivariate...

The paper contribute to the assessment of PDO/PGI schemes by building an approach to measuring the actual performance of the PDO/PGI products in relation to the objectives of the European Regulation 510/2006. This is done through a multi-criteria ex-post analysis that compares the performance of different PDO/PGI products with respect to multiple criteria. The research presented, based on a small sample of Pdo cheese products in Italy, can be considered a pilot study that develops a comparative evaluation of the performance of PDO cheeses: i) relative to the different objectives of the schemes, ii) by using a set of suitable and informative indicators that can help to evaluate the effectiveness of a wide number of PDOs/PGIs with respect to the regulation’s...

This paper develops a multi-regional general equilibrium model (MEG-R) to compare the social desirability of the CAP reform in the three Italian macro-regions: North, Center and South. The model employs a mixed complementary framework that allows for the decision of not producing a particular crop in one or more regions and presents an attempt to model interregional trade flows. The model incorporates the links between production and consumption that characterize farm household’s behavior and allows for heterogeneous household responses across regions. Results show a general tendency to reallocations from cereal crops to forage that appear more severe in the South. In this region, the reduction in crops cannot be translated into an effective expansion of...

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

A Need for Caution in Applying the Volume-Based Special Safeguard Mechanism
Provedor de dados: 31
Autores: Ivanic,   Maros; Martin,   William J.
The proximate cause of the collapse of the Doha Agenda negotiations in 2008 was disagreement over the volume-based Special Safeguard Mechanism (SSM). This measure would provide a right, but not an obligation, for developing countries to impose a duty when imports increase. While many simulations of its impact on domestic prices are available, there appear to be no analyses of its potential impacts on the welfare of poor households. Whether such a safeguard will increase or reduce poverty can only be determined empirically—if there are enough small, poor farmers who are net sellers of the commodity when the duty is imposed, then imposition of a safeguard duty may reduce poverty. If, by contrast, most small, poor farmers are net buyers of the products...

A neural model for the visual tuning properties of action-selective neurons
Provedor de dados: 17
Autores: Martin A. Giese; Vittorio Caggiano; Falk Fleischer.
SUMMARY: The recognition of actions of conspecifics is crucial for survival and social interaction. Most current models on the recognition of transitive (goal-directed) actions rely on the hypothesized role of internal motor simulations for action recognition. However, these models do not specify how visual information can be processed by cortical mechanisms in order to be compared with such motor representations. This raises the question how such visual processing might be accomplished, and in how far motor processing is critical in order to account for the visual properties of action-selective neurons.&amp;#xd;&amp;#xa;We present a neural model for the visual processing of transient actions that is consistent with physiological data and that accomplishes...

A new analytical formulation of retention effects on particle diffusion processes
Provedor de dados: 42
Autores: Bevilacqua,Luiz; Galeão,Augusto C.N.R.; Costa,Flavio P.
The ultimate purpose of this paper is to present a new analytical formulation to simulate diffusion with retention in a reactive medium under stable thermodynamic conditions. The analysis of diffusion with retention in a continuum medium is developed after the solution of an equivalent problem using a discrete approach. The new law may be interpreted as the reduction of all diffusion processes with retention to a unifying phenomenon that can adequately simulate the retention effect namely a circulatory motion. It is remarkable that the governing equation requires a fourth order differential term as suggested by the discrete approach. The relative fraction of diffusion particles β is introduced as a control parameter in the diffusion-retention law as...

A new spinosaurid taxon, Oxalaia quilombensis gen. et sp. nov., is described based on the anterior part of a snout and a fragment of a maxilla. These specimens were collected at the Laje do Coringa site, Late Cretaceous (Cenomanian) of the São Luis Basin. Unlike Cristatusaurus and Suchomimus, Oxalaia quilombensis lacks serrations on the teeth. The new species differs from Angaturama limai by having the anterior part of the premaxillae more expanded and by lacking a sagittal premaxillary crest. It further differs from Spinosaurus cf. S. aegyptiacus and the Algerian spinosaurid by the rounder shape of the terminal expansion. Furthermore, xalaia quilobensis has one functional tooth followed by two replacement teeth, a feature not previously observed in...

A new econometric test for asymmetric price adjustment by cointegration vector restrictions with an application to the U.S. and Dutch pork chains
Provedor de dados: 31
Autores: Kuiper,   W. Erno; Pennings,   Joost M.E.; Verhees,   Frans J.H.M.
A new test of asymmetric price adjustment is proposed on the basis of the super-consistent cointegrating vector estimator in the Johansen (1995) cointegrating procedure. The super-consistency makes the test robust to misspecifications in the short-run model. Application of the test to the price spreads in the Dutch and U.S. pork chains reveals that in the Netherlands wholesalers might obtain extra price margin as a consequence of asymmetric price adjustment vis-à-vis the farmers.

A new functional role for lateral inhibition in the striatum: Pavlovian conditioning
Provedor de dados: 17
Autores: Patrick Connor; Thomas Trappenberg.
The striatum has long been implicated in reinforcement learning and has been suggested by several neurophysiological studies as the substrate for encoding the reward value of stimuli. Reward prediction error (RPE) has been used in several basal ganglia models as the underlying learning signal, which leads to Pavlovian conditioning abilities that can be simulated by the Rescorla-Wagner model.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Lateral inhibition between striatal projection neurons was once thought to have a winner-take-all function, useful in selecting between possible actions. However, it has been noted that the necessary reciprocal connections for this interpretation are too few, and the relative strength of these synaptic connections is weak. Still,...

A New General Allometric Biomass Model
Provedor de dados: 17
Autores: Wei Sheng Zeng; Shou Zheng Tang.
To implement monitoring and assessment of national forest biomass, it is becoming the trend to develop generalized single-tree biomass models suitable for large scale forest biomass estimation. Considering that the theoretical biomass allometric model developed by West et al. [1,2] was statistically different from the empirical one, the two parameters in the most commonly used biomass equation M=aDb were analyzed in this paper. Firstly, based on the knowledge of geometry, the theoretical value of parameter b was deduced, i.e., b=7/3(~2.33), and the comparison with many empirical studies conducted throughout the globe indicated that the theoretical parameter could describe soundly the average allometric relationship between aboveground biomass M and D...

A new genus and species of Euptychiina (Lepidoptera: Nymphalidae: Satyrinae) from southern Brazil
Provedor de dados: 82
Autores: Freitas,AVL; Mielke,OHH; Moser,A; Silva-Brandão,KL; Iserhard,CA.
This paper describes a new genus and a new species of Euptychiina from open grassland habitats (campos de cima da serra) in southern Brazil. The systematic position of this new taxon is discussed based on morphological and molecular data, and it is considered sister to Taydebis Freitas. Since the campos vegetation is considered endangered due to anthropogenic activities, this butterfly species deserves attention and should be included in future conservation plans for this biome.

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

A new genus of dipnoiformes from the Cretaceous of Brazil
Provedor de dados: 42
Autores: Toledo,Carlos E.V.; Sousa,Eliane P. de; Medeiros,Manuel A.A.; Bertini,Reinaldo J.
The Alcântara Formation, an important stratigraphic unit from the early Cenomanian of Brazil, was deposited under transitional (estuarine) conditions, and its fossil record includes fragmentary remains of plants, fishes, crocodylomorphs, pterosaurs and dinosaurs, with a noteworthy diversity of dipnoiformes tooth plates. The dipnoiformes material reported here comprises a new taxon, Equinoxiodus alcantarensis, gen. et sp. nov. Most of the identified morphotypes of continental vertebrates collected in the Alcântara Formation are similar to chronocorrelative faunas from Northern Africa, but this new genus of Dipnoiformes indicates some degree of paleogeographic isolation and endemism. This was probably caused by the widening of the equatorial Atlantic Ocean...

Provedor de dados: 103
Autores: Souza,Ana L. G; Corrêa,Margaret M. de O; Aguilar,Cecília T. de; Pessôa,Leila M.
A new karyotype of Wiedomys pyrrhorhinus (Wied, 1821) is described, including G- and C-banding and Ag-NOR sites from specimens collected in the municipality of Morro do Chapéu, situated in the northern region of the Chapada Diamantina, state of Bahia. Karyological studies of W. pyrrhorhinus have shown a constant diploid number (2n) of 62 with two different numbers of autosomal arms (FNa): 86 and 90, respectively. The new karyotype revealed 2n = 62 and FNa = 104, being the higher autosomal number found so far for this genus. The X chromosome is a large acrocentric and the Y chromosome is a small acrocentric. The analysis of the karyotype morphology suggests that this new karyotype is more closely related to the previous karyotype with 2n = 62 and FNa = 90,...

A new look into the small-scale dispersal of free-living marine nematodes
Provedor de dados: 103
Autores: Thomas,Micheli C; Lana,Paulo C.
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m and 1 m from the stained cores, sampling nets were suspended 5 and 10 cm above the sediment-water interface. Dispersion behaviors were defined as a function of a) the numbers of stained recaptured nematodes in comparison to their mean densities in the sediment, b) movement in the sediment or swimming in the water column, and c) body morphology. Tidal currents with average velocities of 9 cm/s resuspended...

A New Measure of the Producer Welfare Effects of Technological Change
Provedor de dados: 31
Autores: Bullock,   David S.
It is well recognized that the statistical reliability of the conventional method of estimating the effects of technological change on producer welfare is often quite poor.  I present a method that enhances the statistical reliability of such estimates.  I emphasize that when measuring the welfare effects of technological change, valuable information can be gleaned from data on input prices and quantities.  This type of data is often available, but the conventional measure typically does not take full advantage of its availability.  Letting T0 be some initial level of technology and T1 be a subsequent level, the conventional measure of producer welfare change due to a technology change is the change in the “triangle” area under the price and behind the...

A new northern distribution limit of Abrocoma bennettii (Rodentia, Abrocomidae) in the coastal Atacama desert, Paposo, north of Chile
Provedor de dados: 81
Autores: Guzmán,Jonathan A.; Sielfeld,Walter.
Abrocoma bennettii is a relatively robust abrocomid rodent endemic to Chile. It is distributed from approximately 27°18'S - 70°25'W in the north (Atacama) to 36°00'S - 73°7'W in the south (BíoBío). We report the finding of a cranium in excellent conditions, which is the first record of this species in the coastal shrubby Mediterranean desert of the Antofagasta Region. The record of A. bennettii in the locality of Paposo (25º00'S - 70º27'W; 648 m) represents an extension of about 280 km to the northeast of its previously known distribution in the Atacama Region of Chile.

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

A new record of Equus (Mammalia: Equidae) from the Late Pleistocene of central-south Chile
Provedor de dados: 97
Autores: RECABARREN,OMAR P; PINO,MARIO; CID,INÉS.
Fourteen dental and bone parts of a horse excavated from the Pilauco paleontological site, Osorno (40°39' S-73°07' W) are analysed and interpreted. This site was formed in association with a peat bog located on the banks of the old Damas River and has conserved abundant late Pleistocene mammalian fauna and flora materials. A date of 11457 ± 140 14C yrs B.P. was obtained from a molar and agrees with our stratigraphic age model. We have identified the fossils as pertaining to the species Equus (Amerhippus) andium, which confirms its presence in central-south Chile. Furthermore, the recorded geographic location indicate that the metapodial adaptations of the specimens previously described agree with the reconstructed late Pleistocene landscape of Pilauco,...

Here we report on a new small deinonychosaurian theropod, Pamparaptor micros gen. et sp. nov., from the Late Cretaceous of Patagônia, Argentina. Pamparaptor micros exhibits a pedal structure previously unknown among South Américan deinonychosaurians. The new material provides new evidence about the morphology and taxonomic diversity of Patagônian deinonychosaurs. Pamparaptor is the smaller non-avialae Patagônian deinonychosaur, probably with about 0.50-0.70 meters, long. The pedal construction resembles, that of Troodontid or basal Dromaeosaurids. Nevertheless, up to now, we considered Pamparaptor a peculiar Patagônian Dromaeosaurid with troodontid-like pes.

A new species of Bryconops (Teleostei: Characidae) from the rio Madeira basin, Northern Brazil
Provedor de dados: 83
Autores: Wingert,Juliana M.; Malabarba,Luiz R.
A new species of Bryconops is described from a tributary to the rio Madeira in the Amazon basin, State of Rondônia, Brazil. Bryconops piracolina belongs to the subgenus Bryconops by having no teeth or rarely one tooth in the maxilla, and a naked area on cheek between the second and third infraorbitals. The new species is distinguished from all species of this subgenus by the presence of a large black blotch on dorsal-fin base. Furthermore, it is distinguished from all congeners, except B. inpai, by possessing the adipose fin entirely black. It differs from B. inpai by the lack of humeral spots. It further differs from all species of the subgenus Bryconops, except B. caudomaculatus, by having the last scales of the longitudinal series of scales that bears...

A new species of sand-dwelling catfish, with a phylogenetic diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae)
Provedor de dados: 83
Autores: Pinna,Mário C. C. de; Kirovsky,Alexandre L.
A new species of sand-dwelling catfish genus Pygidianops, P. amphioxus, is described from the Negro and lower Amazon basins. The new species differs from its three congeners in the elongate eel-like body, the short barbels, and the small caudal fin, continuous with the body, among other traits of internal anatomy. The absence of anal fin further distinguishes P. amphioxus from all other Pygidianops species except P. magoi and the presence of eyes from all except P. cuao. The new Pygidianops seems to be the sister species to P. magoi, the two species sharing a unique mesethmoid with a dorsally-bent tip lacking cornua, and a produced articular process in the palatine for the articulation with the neurocranium. Pygidianops amphioxus is a permanent and...

Seira Lubbock, 1869 is the most speciose genus of Collembola in Brazil. Herein, we describe and illustrate a new species of Seira, Seira ritae sp. nov., collected in João Pessoa, state of Paraíba, Brazil, in an urban seaside area. The new species shows many similarities with S. mendoncea Bellini &amp;amp; Zeppelini, 2009 especially in what concerns the dorsal distribution of the macrochaetae of the head, the metathorax, and the first three abdominal segments. However, the two species can be distinguished by the chaetotaxy of the mesothorax and abdominal segment IV. The type locality of the species probably indicates some level of natural resistance to the impacts associated with human activities.

A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.

A new species of Tetragonopterus is described from the rio Jari, a tributary to the left margin of rio Amazonas, at the border between Amapá and Pará States, northern Brazil. It is morphologically diagnosed from the other species of the genus (T. argenteus, T. chalceus, and T. rarus new combination) by the lozenge-shaped spot on the caudal peduncle vs. rounded to square spot on the other species. Partial sequences of the mitochondrial gene Cytochrome Oxidase C subunit I, from representatives of all valid species of Tetragonopterus, including this new species, were analyzed. The obtained results revealed a significant genetic distance between the new species and its congeners. A discussion on the new combination, Tetragonopterus rarus, is also provided.

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

Autores: Kellner,Alexander W.A.; Rubilar-Rogers,David; Vargas,Alexander; Suárez,Mario.
Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and a new species, Atacamatitan chilensis gen. et sp. nov., is erected. The material consists mainly of dorsal and caudal vertebrae, part of a humerus and a femur. The presence of a titanosaur confirms the Cretaceous age for the outcrops of red sandstone of the Tolar Formation whose age was previously uncertain, ranging from the Upper Cretaceous to the Paleocene. The new specimen represents the most complete dinosaur reported for this region and one of the most complete titanosaur known from Chile and the pacific margin of South America so far.

Provedor de dados: 80
Autores: Ozkan,O; Yagmur,EA; Ark,M.
Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identified as L. quinquestriatus in Turkey) was classified as a new Leiurus species. This is the first report conducted on the lethality and biologic effects of L. abdullahbayrami scorpion venom in mice. In this study, the electrophoretic protein pattern of its venom was also determined. Two protein bands with molecular masses of 4 and 6 kDa were more strongly detected than other protein bands in the venom...

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

A Nonlinear Offset Program to Reduce Nitrous Oxide Emissions Induced by Excessive Nitrogen Application
Provedor de dados: 31
Autores: Rosas,   Francisco; Babcock,   Bruce A.; Hayes,   Dermot J.
On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative environmental consequences because the nitrogen that is not taken up by the plant will typically volatilize causing N2O emissions, or leach causing water pollution. We present a nonlinear offset program that induces farmers to reduce their nitrogen applications to the level that will be consumed by the plant in a typical year and, as a result, reduce N2O emissions from agriculture. The offset program is nonlinear because of the nonlinear relationship between N2O...

A nonspecific primer anchored PCR technique for chromosome walking
Provedor de dados: 52
Autores: Zhang,Yan; Liu,Daqun; Yang,Wenxiang; Li,Yaning; Yan,Hongfei.
A chromosome walking method was improved in this work. The new method was named as nonspecific primer anchored PCR (NPA-PCR). Nested gene specific primers were designed based on the known region and long random primer using degeneracy oligonucleotides for nonspecific anchoring. Annealing temperatures were varied to control the priming. Target sequences were obtained by PCR with random primer and gene-specific primer. Nonspecific sequence with long random primers at both ends formed stem loop structure due to inverted terminal repeats. The method was employed to isolate a gene with newly-isolated actinomycin producing strain Streptomyces setonii Z-L-22. A 0.77 kb fragment of actinomycin synthetase gene cluster was isolated from the strain. The fragments of...

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

A note on the performance measure of conservation auctions
Provedor de dados: 31
Autores: Latacz-Lohmann,   Uwe; Schilizzi,   Steven.
We argue that previous assessments of discriminatory-price conservation auctions may have systematically overestimated their performance relative to uniform-payment schemes due to an inappropriate counterfactual comparison. We demonstrate that the cost curve (and not the bid curve) is the relevant supply curve when a uniform payment is offered and provide a theoretically rigorous counterfactual based on that insight. We estimate that the performance of BushTender may have been overrated by more than 50%.

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

A novel alveolar Krebs cycle-triggered CO2 sensing mechanism regulates regional pulmonary ventilation.
Provedor de dados: 17
Autores: Rainer Kiefmann; Paula Keller; Oliver Tritt; Kai Heckel; Sascha Tank; Martina Kiefmann; Leoni Schulte-Uentrop; Alwin Goetz.
Pulmonary perfusion disorders provoke atelectasis in order to minimize ventilation/perfusion mismatch. However, the underlying mechanisms remain unknown. Because intraalveolar CO2 concentration ([CO2]iA) declines as a consequence of poor pulmonary perfusion we postulated the existence a novel alveolar CO2-sensing mechanism which adapts the ventilation to perfusion. Real-time fluorescence imaging of rat lungs revealed that low [CO2]iA decreased cytosolic and increased mitochondrial Ca2+ in alveolar epithelial cells (AEC), leading to reduction of surfactant secretion and alveolar ventilation. Mitochondrial inhibition by ruthenium red or rotenone blocked the hypocapnia-induced responses. In cultured Type 2 AEC hypocapnia decreased cytosolic Ca2+ independently...

A Novel Thermodynamic Method For Quantifying Ligand-Receptor Interactions: The IC (1/3) Standard Vs IC (50)
Provedor de dados: 17
Autores: Dr Sudarsan Prasad.
A method based on the Concentration Derivative Product (CDP) is proposed to analyze the thermodynamics of Drug-Receptor interactions. CDP is defined as the product of the fractional inhibition f and it&amp;#x2019;s concentration derivative. Assuming Michaelis-Menten kinetics, it is shown that for a number of drug-receptor systems (HIV protease, ACE, HMG-CoA, Opioid receptor inhibitors, etc.) f max  = 0.333, irrespective of the nature of bonding interactions and Ki.   The CDP max = [4 / ( 27 Ki ) ], and gives a measure of the drug potency directly. CDP also gives thermodynamic information about the ratio of the gradients of the inhibitor chemical potential in the free and bound states.

A Numerical Investigation for Underwater Fluid-Netting Interaction Problem

The present work investigates an application-oriented issue in the marine and fisheries researches domain. However much trawl structure codes that simulate dynamic behavior of submerged nets, in continuous interaction with surrounded ocean water, still need more accuracy and precision due to the fact that the sea water is mainly considered as a fluid with a uniform velocity and intensity, and so the effects of small turbulence rates were neglected. When this little inaccuracy occurs in the first step of the net displacement prediction, a large error could manifests in the form of the simulated net, and as consequence, drag forces wrongly estimated. In the purpose to overcome the lack of data information exchange during the fluid structure interaction, a co...

A palynological analysis of a marine sediment core in the southern Philippines, provides a detailed regional vegetation and climate history for the West Pacific Warm Pool (WPWP) since the Last Glacial Maximum (LGM). Chronology was determined by a detailed oxygen isotope record. A higher representation of pollen from tropical upper montane rainforest during the LGM indicate that this forest type moved down along elevation, probabaly due to the lowered temperature. During the last deglaciation and the early Holocene, mangroves were more expanded and tropical mid and upper montane rainforests were restricted, suggesting a rising sea-level and temperature increase. Herbaceous pollen and pteridophyte spore records indicate a much drier condition during the LGM...

A physiological and biochemical approach to selecting the ideal diet for Ostrea edulis (L.) broodstock conditioning (part A)
Provedor de dados: 5
Autores: Gonzalez-araya, Ricardo; Queau, Isabelle; Quere, Claudie; Moal, Jeanne; Robert, Rene.
To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T-ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica&lt;C. gracilis&lt;S. marinoï. When oysters were fed either...

The goal of watershed scale analysis is to assign to each field unit the best set of agricultural practices in order to achieve a maximum outcome from both environmental and economic perspectives. Watershed physically based models linked to multiobjective optimization models can overcome the high dimensionality of watershed pollution problem. Market based instruments such as permit trading settings which consider abatement measures’ cost heterogeneity have been regarded as being superior to command and control programs. Empirical analysis reveals that when local environmental authority and farmers have different cost information, a permit trading program has the potential to offer cost savings.

Provedor de dados: 74
Autores: Boto,Luis; Cunha,Carina; Doadrio,Ignacio.
A new microsatellite locus (SAS1) for Squalius alburnoides was obtained through cloning by serendipity. The possible usefulness of this new species-specific microsatellite in genetic studies of this hybrid-species complex, was explored. The polymorphism exhibited by SAS1 microsatellite is an important addition to the set of microsatellites previously used in genetic studies in S. alburnoides complex, that mostly relied in markers described for other species. Moreover, the SAS1 microsatellite could be used to identify the parental genomes of the complex, complementing other methods recently described for the same purpose.

A Possible Solution to the Etiological Paradox that Ties Anti-Social Personality Disorder to Major Depression
Provedor de dados: 17
Autores: Alvaro Machado Dias.
Abstract. Antisocial personality disorder (ASPD) is a pervasive condition among youngsters around the globe, which has particular pungency in countries where the socioeconomic context favors delinquency. Several behavioral genetics studies have linked the disorder to the presence of copies of a polymorphic variation of the MAO-A gene that leads to enzymatic hypofunction.  An emerging tendency in this literature is to also associate it to the presence of short variations of the 5-HTTLPR polymorphism, which is well-known for its possible role in the vulnerability to major depression of individuals that were exposed to early-life stress. The current paper argues that the association of these findings introduce a theoretical problem that is not trivial...

Autores: Paull, John.
It is easy to imagine that Rudolf Steiner (1861­‐1925) would be delighted with the new exhibition 'Kosmos Rudolf Steiner' at Stuttgart's modernistic Kunstmuseum. Kosmos is a major retrospective exhibition of Steiner's life and ideas. Kosmos appears 150 years after Steiner's birth, and this is a timely anniversary to present the manand his ideas, fresh to a new audience. Kosmos Rudolf Steiner is, first and foremost, a celebration of a life lived with intensity, purpose and zest. Visitors may be drawn by curiosity, and others will be drawn by familiarity. Whether it was art, agriculture, architecture or anthroposophy, whether education or eurythmy, furniture or well-­‐being, Steiner touched it, and his touch has endured. After Stuttgart, the exhibition moves...

A potential cyanobacterial ancestor of Viridiplantae chloroplasts
Provedor de dados: 17
Autores: Wriddhiman Ghosh; Prabir Haldar; Sabyasachi Bhattacharya; Jaideb Chatterjee; Prosenjit Pyne; Masrure Alam.
The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups. It is widely believed that primordial endosymbiosis occurred in the last common ancestor of all algae^1^, which then diverged into the three primary photosynthetic eukaryotic lineages, viz. the Rhodophyta (red algae), Glaucocystophyta (cyanelle-containing algae) and Viridiplantae (green algae plus all land plants)^2^. Members of these three groups invariably have double membrane-bound plastids^3^, a property that endorses the primary endosymbiotic origin of the organelles. On the other hand, the three or four membrane-bound plastids of the evolutionary...

Autores: Acevedo,Francisca; Pizzul,Leticia; Castillo,María del Pilar; Rubilar,Olga; Lienqueo,María Elena; Tortella,Gonzalo; Diez,María Cristina.
In this study, different growth conditions of Anthracophyllum discolor Sp4 including the effect of agitation, additions of lignocellulosic support, inducer and surfactant were evaluated on the MnP production in Kirk medium using a culture system made up of the tubes containing the glass bead . The highest MnP production (1,354 U/L on day 13) was obtained when the medium was supplemented with wheat grain and 0.25 mM MnSO4 as inducer, under static conditions at 30°C. Two isoenzymes were purified (35 and 38 kDa respectively). MnP presented a maximal activity in the pH range between 4.5 and 5.5, a relatively high temperature tolerance (50ºC) and a high catalytic activity for 2,6-dimethoxyphenol and hydrogen peroxide.

Autores: Cui,Yihong; Zhu,Guangqin; Chen,Qiuju; Wang,Yunfei; Yang,Mingming; Song,Yuxuan; Wang,Jiangang; Cao,Binyun.
Complementary DNA (cDNA) is valuable for investigating protein structure and function in the research of life science, but it is difficult to obtain by traditional reverse transcription. In this study, we employed a novel strategy to clone the human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA directly isolated from the mucous membrane of mouth. The hLIF sequence can be acquired within a few hours by means of amplification of each exon and splicing using overlap-PCR. Thus, the new approach developed in this study is simple, time- and cost-effective, and it is not limited to particular gene expression levels of each tissue.

A preliminary evaluation of matricaria maritimum fibres for polymer reinforcement
Provedor de dados: 5
Autores: Davies, Peter; Bourmaud, A.; Pajot, A.; Baley, C.
This short communication describes results from a preliminary characterization of the dimensions and mechanical properties of matricaria maritimum fibres. The aim is to develop a complementary industrial application of these plants, which are grown along the coast mainly for pharmaceutical use. The fibres are shown to be of small diameter, 5-10 mu m, and tubular in form. Nano-indentation on fibres and tensile tests on fibre bundles provide an indication of the mechanical behaviour of these fibres, which are similar to those of sisal (leaf fibre) and miscanthus (grass fibre), and may be interesting for reinforcement of polymer matrix composites.

Provedor de dados: 25
Autores: Lima, Flavio Jorge; Fortes Neto, Paulo; Batista, Getulio Teixeira.
A bibliografia estudada para discutir a sustentabilidade da produção mineral aponta para duas correntes que debatem o assunto, caracterizadas de acordo com o ponto central das teses: a dos recursos fixos e custos oportunidades. A primeira encara os recursos explorados pela mineração como não renováveis e passíveis de exaustão. A segunda indica que novas tecnologias suprirão as demandas futuras à medida que os recursos poderão ser extraídos de fontes com menor concentração de minérios. Ambas pressupõem que o Estado poderia interferir incisivamente na questão da internalização dos custos da produção e da recuperação dos impactos ambientais. Legalmente, o Estado instituiu o principio “poluidor-pagador”, que parece não atender efetivamente a demanda degradante...

A project-based system for including farmers in the EU ETS
Provedor de dados: 21
Autores: Svendsen, Gert Tinggaard; Brandt, Urs Steiner.
Farmers in the EU do not trade greenhouse gases under the  Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices as ‘the missing link’ in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either...

The German Escherichia coli O104:H4 outbreak causing Hemolytic Uremic Syndrome (HUS) started in early May 2011. Conventional typing methods including serotyping, multi-locus sequence typing (MLST) and pulse-field gel electrophoresis (PFGE) seemed to yield only limited information about the causative agent. The advantages of the Genome sequencing approach are apparent compared to conventional methods. Genome sequencing and analyses with an appropriate workflow would be the new paradigm in bacterial outbreak investigation.

A pterodactyloid pterosaur from the Upper Cretaceous Lapurr sandstone, West Turkana, Kenya
Provedor de dados: 42
Autores: O'Connor,Patrick M.; Sertich,Joseph J.W.; Manthi,Fredrick K.
An isolated pterosaurian caudal cervical (~ postcervical) vertebra was recovered from the Upper Cretaceous Lapurr sandstone ofWest Turkana, northwestern Kenya. The vertebral centrum is short, wide, and dorsoventrally compressed. Although the specimen is lightly built similar to most pterosaurs, it is here referred to Pterodactyloidea and tentatively to the Azhdarchidae in that it lacks pneumatic features on both the centrum and neural arch. This represents one of the few pterosaurs recovered from the entirety of Afro-Arabia, the first pterosaur recovered from the Cretaceous of East Africa, and, significantly, a specimen that was recovered from fluvial deposits rather than the near-shore marine setting typical of most pterosaur discoveries.

Little is known about the etiology of progressive macular hypomelanosis, although it has been suggested that Propionibacterium acnes plays an important role. While microbiological culture is commonly employed to identify Propionibacterium acnes, new identification methods have been under investigation, amongst them polymerase chain reaction. To determine the cut-off point for the number of genome copies of Propionibacterium acnes in the lesional skin of patients with progressive macular hypomelanosis as a positive marker, employing quantitative real-time polymerase chain reaction and anaerobic culture, considered gold standard.

A Quantitative Approach to Investigating the Hypothesis of Prokaryotic Intron Loss
Provedor de dados: 17
Autores: Robert M. Sinclair.
Using a novel method, we show that ordered triplets of motifs usually associated with spliceosomal intron recognition are underrepresented in the protein coding sequence of complete Thermotogae, archaeal and bacterial genomes. The underrepresentation observed does not extend to the noncoding strand, suggesting that the cause of the asymmetry is related to mRNA rather than DNA. Our data do not suggest that the underrepresentation is due to gene transfer from eukaryotes. We speculate that one possible explanation for these observations is that the protein coding sequence of Thermotogae, Archaea and Bacteria was at some time in the past subjected to selection against certain motifs appearing in an order which might initiate splicing in environments harboring...

A real-time PCR genotyping assay to detect FAD2A SNPs in peanuts (Arachis hypogaea L.)
Provedor de dados: 69
Autores: Barkley,Noelle A; Wang,Ming Li; Pittman,Roy N.
The high oleic (C18:1) phenotype in peanuts has been previously demonstrated to result from a homozygous recessive genotype (ol1ol1ol2ol2) in two homeologous fatty acid desaturase genes (FAD2A and FAD2B) with two key SNPs. These mutant SNPs, specifically G448A in FAD2A and 442insA in FAD2B, significantly limit the normal function of the desaturase enzyme activity which converts oleic acid into linoleic acid by the addition of a second double bond in the hydrocarbon chain. Previously, a genotyping assay was developed to detect wild type and mutant alleles in FAD2B. A real-time PCR assay has now been developed to detect wild type and mutant alleles (G448A) in FAD2A using either seed or leaf tissue. This assay was demonstrated to be applicable for the...

The aim of this work was to determine the correlation between results obtained from the Draize test and from the Total Protein Content Determination (TPC) to assess the ocular irritancy potential of 20 shampoos. For TPC, two established cell lines (SIRC and 3T3) were used. The concentration that induced 50% inhibition relative to controls (IC50) was calculated for each product. Among shampoos tested with SIRC, only one had a false positive result. However, for the 3T3, three false-negative results were found. Pearson coefficient related to the in vivo value of maximum average score (MAS) was -0.58 (p=0.007) with SIRC and -0.73 (p=0.007) with 3T3. These results showed that the TPC assay was capable to predict the ocular irritant potential of shampoos, and...

A regional analysis of CAP expenditure in Austria
Provedor de dados: 31
Autores: Strahl,   Wibke; Dax,   Thomas; Hovorka,   Gerhard.
This paper reflects the demand for taking account of the territorial dimension in the application of Common Agricultural Policy (CAP) more comprehensively. While this has been addressed in rural development discourse to a wide extent over the last two decades and consensus for regionalized strategies is emerging, programme evaluation is in general still limited to the analysis of policy interventions at the national level. This implies that conclusions on the territorial effects of CAP are largely missing. Therefore the intention of this paper is to provide a regional analysis of CAP expenditures for pillar 1 and pillar 2, and to demonstrate and assess their actual territorial impacts, represented on the basis of the NUTS 3 region ‘Obersteiermark West’:...

A remarkable new Middle Sandbian (Ordovician) hexactinellid sponge in Baltic erratics
Provedor de dados: 16
Autores: Botting, J.P.; Rhebergen, F.
A new species of complex hexactinellid sponge, Haljalaspongia inaudita, is described from fluvially transported blocks found in northwestern Germany, near the Dutch border, but which probably originated from the eastern Baltic region. The heavily folded wall is composed of multiple spicule layers, including dermal and gastral layers of acanthohexactines, and a central layer of sub-parallel monaxons. The monaxial layer is lined on one side by a reticulate array of smooth monaxons. The sponge is difficult to assign to any known fossil or recent group, but shares some features with the dictyospongioid family Docodermatidae.

A Review of FDA Imports Refusals - US Seafood Trade 2000-2010
Provedor de dados: 31
Autores: Anders,   Sven M.; Westra,   Sabrina.
The United States is the third largest consumer of seafood products in the world. The percentage of imported seafood consumed in the U.S. has steadily increased from 66% in 1999 to over 84% in 2009 (NOAA, 2010). Food safety, especially of imported foods and products from developing countries, has raised increasing concerns among American consumers and policy makers. Accordingly, the Food and Drug Administration’s (FDA) (Ababouch et al. 2000) border inspection system is considered critical for ensuring the safety of domestic seafood consumers. However, the potential non-tariff barrier to trade posed by FDA regulations, especially for many developing country exporters have been frequently cited in the literature.  This paper investigates trends and patterns...

A REVIEW OF FOOD SECURITY AND HUMAN NUTRITION ISSUES IN NEPAL
Provedor de dados: 31
Autores: Shively,   Gerald E.; Gars,   Jared; Sununtnasuk,   Celeste.
Nepal faces multiple development challenges, including chronic and widespread food insecurity and adult and child malnutrition. Due to population growth, agricultural stagnation and a range of institutional failures, the threat of a serious food crisis in Nepal is substantial. The recent scaling back of WFP assistance means that food security conditions in some parts of Nepal will undoubtedly worsen in the near future. This paper presents a brief review of topics and available evidence regarding food security, malnutrition and related subjects in Nepal. It is intended to document important source material and provide an overview of topics for non-specialists or those moving into new areas of concern.

A Review of Municipal Bond Issues in Michigan
Provedor de dados: 31
Autores: Scorsone,   Eric; Plerhoples,   Christina.
Municipal bonds have recently been of national interest and Michigan’s strained economy over the past decade has made bond issuance in the state of particular interest to a variety of stakeholders. Given the close connection between municipal bonds and property taxes, the fall-off in the housing market has placed significant strain on bonds within the state.  This paper reviews the Michigan municipal bond condition and develops a new debt assessment indicator system.  This system was tested using over 700 Michigan local governments. Based on this indicator system, a number of communities are experiencing significant fiscal stress.  However, further examination reveals that at least some of these communities have in place short term plans to address such...

A review of undulated sediment features on Mediterranean prodeltas: distinguishing sediment transport structures from sediment deformation
Provedor de dados: 5
Autores: Urgeles, Roger; Cattaneo, Antonio; Puig, Pere; Liquete, Camino; De Mol, Ben; Amblas, David; Sultan, Nabil; Trincardi, Fabio.
Most Mediterranean prodeltas show undulated sediment features on the foresets of their Holocene wedges. These features have been described all along the Mediterranean for the last 30 years and interpreted as either soft sediment deformation and incipient landsliding, and more recently, as sediment transport structures. We perform a review and detailed analysis of these undulated sediment features using ultrahigh-resolution seismic and bathymetric data as well as geotechnical information and hydrodynamic time series and hydrographic transects. In this study we show that the characteristics of the sediment undulations (configuration of the reflections down section and between adjacent undulations and overall morphologic characteristics) are incompatible with...

A revised calendar age for the last reconnection of the Black Sea to the global ocean
Provedor de dados: 5
Autores: Soulet, Guillaume; Menot, G.; Lericolais, Gilles; Bard, E.
During the last decade, a debate arose regarding the timing and pattern of the last reconnection of the Black Sea "Lake" with the global ocean. On a geochemical basis, the radiocarbon age of Black Sea "Lake" surface water, during the time of reconnection, was determined to be similar to 8400 C-14 a. BP. Despite the potential bias induced by the hard water effect in lakes, the reconnection age was calibrated without any reservoir age correction, which led to an estimate of similar to 9400 cal a. BR Since knowledge for the actual calendar age has important hydrologic implications that would provide new insights regarding the mechanism of reconnection, determining the actual calendar age for the last reconnection remains important. Based upon modeling...

Autores: Garcia Sanchez,E; Ramirez Lopez,CB; del Rio Torres,REN; Martinez Pacheco,MM.
An important study in species of the genus Eupatorium, that inhabits other parts of the world, was conducted in the search for new molecules with pharmacological activities, thus showing that it is a potential source of novel secondary metabolites. We reviewed the number of Eupatorium species that have been described in the State of Michoacan, and that can be available for harvesting, to make a phytochemical screening. It was found that 69 Eupatorium spp are growing in 69% of the Michoacan territory. Within this group there are ten species used in Mexican traditional medicine. It was evident the difficulty in taxonomic classifying these species since several Eupatorium spp have synonyms. It appeared that the number of native members should be reduced in...

Autores: Soliman,   T.; Hengeveld,   G.M.; Robinet,   C.; Mourits,   Monique; van der Werf,   Wopke; Oude Lansink,   Alfons G.J.M.
Pine wood nematode, B. xylophilus poses a serious threat for the European forest industry. This study applies a quantitative risk assessment to analyze the risk of pine wood nematode in the EU, by estimating the reduction expected within forestry stock available for wood supply and its downstream roundwood market. Spatial analysis is used to join information on climate suitability, host distribution, pest spread and value of assets. Economic impacts are presented spatially on a NUTS-2 scale based on partial budgeting technique and for the EU as a whole based on partial equilibrium modeling. Results highlight the Southern regions of Europe as high risk areas with a total impact on available forestry stock of 19,000 M € after 20 years of an outbreak and no...

A Robust Study of Regression Methods for Crop Yield Data
Provedor de dados: 31
Autores: Zhu,   Ying; Ghosh,   Sujit K.
The objective of this study is to evaluate the robust regression method when detrending the crop yield data. Using a Monte Carlo simulation method, the performance of the proposed Time-Varying Beta method is compared with the previous study of OLS, M-estimator and MM-estimator in an application of crop yield modeling. We analyze the properties of these estimators for outlier-contaminated data in both symmetric and skewed distribution case. The application of these estimation methods is illustrated in an agricultural insurance analysis. The consequence of obtaining more accurate detrending method will offer the potential to improve the accuracy of models used in rating crop insurance contracts.

A sensorimotor area (NIf) is required for the production of learned vocalizations
Provedor de dados: 17
Autores: Sharon M. H. Gobes; Bence P. &amp;#xd6;lveczky.
Sensory feedback is essential for the acquisition of complex motor behaviors, including birdsong. In zebra finches, auditory feedback is relayed to the descending motor pathway primarily through the nucleus interfacialis nidopalii (NIf). NIf projects to HVC - a premotor region essential for song, which projects to RA, a motor cortex analogue brain area that drives muscle activity required for vocalizations. NIf is also essential for &amp;#x2018;sleep replay&amp;#x2019;, a recapitulation of song-related neural dynamics in the motor pathway during sleep. Despite being one of the major inputs to the song control pathway, there is no known role for NIf in the production of zebra finch song. To address this, we reversibly inactivated NIf using TTX or Muscimol...

A similarity criterion for forest growth curves
Provedor de dados: 17
Autores: Georgii A. Alexandrov; Georgy S. Golitsyn.
Comparison of forest growth curves has led many to the conclusion that there is a similarity between forest stands growing in different conditions. Here we treat the same subject from the viewpoint of similarity theory. Our goal is to form a dimensionless ratio of biophysical entities that could parameterize the diversity of forest growth curves. (Such ratios are called similarity criteria.)  Pursuing this goal, we focus on the analogy between tree crown growth and atomic explosion. A blast wave is formed when the rate of energy release is much higher than the rate of energy dissipation. The difference between the rates of energy release and dissipation is the essence of this phenomenon. The essential feature of crown growth is the difference between the...

A simple miniprep based on early elimination of highly acidic and proteinaceous mucilages through ethanol washing of the tissue homogenates has been developed for the extraction of genomic DNA from mature leaves and seeds of Corchorus spp. As compared to high cetyltrimethylammonium bromide (CTAB)-NaCl DNA extraction followed by ethanol-based removal of remnant mucilages from the DNA pellet, this simple miniprep consistently and reproducibly recovers high amounts of DNA with good spectral qualities at A260/A280 and A260/A230. The purified DNA is efficiently digested by restriction endonucleases, and is suitable for PCR amplification of nuclear microsatellites with expected allele sizes.

A simulation study on different STDP models concerning localized gamma oscillations
Provedor de dados: 17
Autores: Florian Hauser; Andreas Knoblauch; G&amp;#xfc;nther Palm.
Gamma oscillations are a prominent feature in experimental as well as theoretical descriptions of brain activity. One of the network models which has the capability to generate such oscillations is what we call a local cell assembly (CA), i.e. a group of neighboring neurons which are strongly interconnected in an excitatory manner. Postulated by experimenters and extensively used in theoretical studies, these local networks seem to be a good candidate for investigating the impact of biological constraints given by models of spike-timing-dependent plasticity (STDP) on local gamma oscillating structures in the mammalian brain. Therefore we fi&amp;#xc;tted a two-compartment neuron model with AMPA- and NMDA-receptor mediated synaptic currents to desired...

A single bio-energetics growth and reproduction model for the oyster Crassostrea gigas in six Atlantic ecosystems
Provedor de dados: 5
Autores: Alunno-bruscia, Marianne; Bourles, Yves; Maurer, Daniele; Robert, Stephane; Mazurie, Joseph; Gangnery, Aline; Goulletquer, Philippe; Pouvreau, Stephane.
Many studies based on bioenergetics growth models have investigated the effects of environmental factors on oyster (Crassostrea gigas) growth and physiology. However, most of these models are site-specific and cannot be applied to other culture sites without the re-estimation of parameters or re-formulation of some processes. We aimed to develop a generic growth model suitable for application in contrasting environments, with a constant set of parameters. We tested the oyster-DEB model (Bourlès et al. 2009) for the stimulation of C. gigas growth in different cohorts (spats and adults) at major shellfish culture sites in France, in several years: Arcachon (1993–1994); Marennes-Oléron (2007); Quiberon (1999, 2000, 2001); Rade de Brest (2008); Baie du...

A snake of a different color: physiological color change in Arizona black rattlesnakes
Provedor de dados: 17
Autores: Melissa Amarello; Jeffrey J. Smith.
Coloration may serve a variety of behavioral (e.g., crypsis, communication) and physiological (e.g., thermoregulation, protection) functions for terrestrial ectotherms.  However, optimal coloration for a given function may vary over environments (spatial or temporal) or conflict with other functions.  Physiological color change (rapid change due to movement of pigment granules within chromatophores) may be an adaptation to resolve conflicting selective pressures on coloration.  The proximate factors related to physiological color change are well known in many animals, but few studies have investigated the ecological or evolutionary implications of this behavior.  Here, we present alternative hypotheses for physiological color change and discuss biotic and...

A Snapshot of the Population Structure of Branchiostoma lanceolatum in the Racou Beach, France, during Its Spawning Season
Provedor de dados: 5
Autores: Desdevises, Yves; Maillet, Vincent; Fuentes, Michael; Escriva, Hector.
A methodology for inducing spawning in captivity of the lancelet Branchiostoma lanceolatum has been developed recently with animals collected at the Racou beach, in the southern coast of France. An increasing amount of laboratories around the world are now working on the evolution of developmental mechanisms (Evo-Devo) using amphioxus collected in this site. Thus, today, the development of new aquaculture techniques for keeping amphioxus in captivity is needed and the study of the natural conditions at which amphioxus is exposed in the Racou beach during their spawning season becomes necessary. We have investigated the amphioxus distribution, size frequency, and population structure in the Racou beach during its natural spawning season using multivariate...

A sorites paradox in the conventional definition of amount of substance
Provedor de dados: 17
Autores: Nigel Wheatley.
The conventional definition of amount of substance _n_ is as a quantity proportional to number of entities _N_. This implies that n is discrete for small _N_ while _n_ is considered to be continuous at the macroscopic scale, leading to a sorites paradox. A practical criterion is proposed for distinguishing between amount of substance and number of entities, and the implications for the conventional definition of amount of substance are discussed.

A Spatial Mathematical Model Analysis of the Linkage between Agricultural Trade and Deforestation
Provedor de dados: 31
Autores: Schmitz,   Christoph; Lotze-Campen,   Hermann.
Like agricultural trade, deforestation has increased tremendously throughout the past five decades. We analyse the linkage between both factors by applying trade and forest policy scenarios to the global land-use model MAgPIE ("Model of Agricultural Production and its Impact on the Environment"). The model predicts global landuse patterns in a spatially explicit way and uses endogenously derived technological change and land expansion rates. Our study is the first which combines global trade analysis with a spatially explicit mapping of deforestation. By implementing self-sufficiency rates in the regional demand and supply equations, we are able to simulate different trade settings. Our baseline scenario fixes current trade patterns until the year 2045....

A Spatiotemporal Fixed Effects Estimation of U.S. State-Level Carbon Dioxide Emissions
Provedor de dados: 31
Autores: Burnett,   J. Wesley; Bergstrom,   John C.
One of the major shortcommings of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored.  By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors).  By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results.  By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics.  To address this potential...

A Stochastic Analysis of the Impact of Volatile World Agricultural Prices on European and UK Agriculture
Provedor de dados: 31
Autores: Moss,   Joan E.; Binfield,   Julian C.R.; Zhang,   Lichun; Patton,   Myles; Kim,   In Seck.
Successive Common Agricultural Policy (CAP) reforms and trade liberalisation have led to a more market-orientated European agricultural sector, with EU commodity prices now more closely linked to world prices. As a consequence EU prices have become more volatile. Greater price volatility increases uncertainty and raises fresh challenges for projections of policy impacts in the EU. To take account of world price volatility stochastic modelling has been applied to the FAPRI-EU partial equilibrium model, which includes a UK modelling system. Stochastic modelling provides a means to capture some of the inherent uncertainty associated with agricultural production systems. By varying assumptions about certain exogenous variables, stochastic models can be used to...

Autores: Onumah,   Edward E.; Acquah,   H. de-Graft.
This paper considers the stochastic production frontier approach to analyse the technical efficiency and its determinants of fish farms in Ghana using a cross-section data of 150 farms. It considers the explicit effects of family and hired labour on production by setting the log-value of the zero-observation of these two sources of labour to zero with dummy variables. Results demonstrate that expected elasticities of mean output with respect to all input variables are positive and significant. Findings also show that family and hired labour used for fish farming in Ghana may be equally productive. Fish farms in Ghana are revealed to be characterised by technology with increasing return to scale. The combined effects of operational and farm specific factors...

A Structural Land-Use Analysis of Agricultural Adaptation to Climate Change: A Proactive Approach
Provedor de dados: 31
Autores: Kaminski,   Jonathan; Kan,   Iddo; Fleischer,   Aliza.
This article proposes a proactive approach for analyzing agricultural adaptation to climate change based on a structural land-use model wherein farmers maximize profit by allocating their land between crop-technology bundles. The profitability of the bundles is a function of four technological attributes via which climate variables‟ effect is channeled: yield potential; input requirements; yields' sensitivity to input use; and farm-level management costs. Proactive adaptation measures are derived by identifying the technological attributes via which climate variables reduce overall agricultural profitability, despite adaptation by land reallocation among bundles. By applying the model to Israel, we find that long-term losses stem from yield potential...

Indian consumers have been buying fish from the unhygienic fish markets, but of late fish has become available at many of the multi-format retail outlets. Consumers’ behaviour at organized fish retail outlets in Mumbai has been studied. The majority of consumers are young (25-35 years) and belong to upper middle class. Fresh fish is the preferred choice and about 60 per cent consumers have emphasized on freshness rather than price of fish. About 97 per cent consumers have recently shifted to organized retail outlets from local markets for purchasing fish. The majority of consumers (84.3%) have been found to be species-specific while buying fish. Quality and convenience have been found to be the major factors responsible for shift from local markets....

Provedor de dados: 77
Autores: Shetty,Surekha D; Nayak B,Satheesha; Madahv,Venu; Braganza,Cilwyn Shalitha; Somayaji,S. N.
Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

A Study on the Variations of Size, Shape and External Features of the Spleen in South Indian Population
Provedor de dados: 77
Autores: Nayak B,Satheesha; Somayaji,S. N; Soumya,K. V.
The spleen is the largest lymphoid organ. It is wedge shaped and measures about 1 inch thick, 3 inches broad and 5 inches long. It presents characteristic notches on its superior margin and has a hilum on the visceral surface. The aim was to study the anomalies related to size, shape and external features of the spleen and discuss their clinical importance. As there are not many reports on variations in size shape and features of spleen in the South Indian population, we decided to do this study on cadaveric specimens. We observed 50 spleens fixed with 10% formalin. Among the 50 spleens observed, 25 spleens (50%) were normal and had all the features explained in the textbooks. 25 spleens (50%) did not have any notches on the superior margin, 2 spleens (4%)...

A System Approach on Organizational Innovations in the Agro-Food Sector: The Case of AFSCs in Flanders
Provedor de dados: 31
Autores: Vandermeulen,   Valerie; Vuylsteke,   Anne; Van Huylenbroeck,   Guido.
Together with the evolution from the agro-industrial model to the sustainable rural development model (Roep and Wiskerke 2004), a part of the agro-food market has evolved from an anonymous, mass food market to a quality-food market. This shift is driven by factors, such as the changing relations between supply chain actors due to concentration in retail and processing, the growing importance of quality standards, considerable changes in consumer habits and preferences, the increasing attention for the multifunctional dimensions of agriculture and the establishment of new markets for public goods and services (Kirwan, Slee et al. 2003; Jahn, Zerger et al. 2007). As a consequence, the contemporary agro-food markets are more and more characterised by...

A system-level neural model of the     brain mechanisms underlying     instrumental devaluation in rats
Provedor de dados: 17
Autores: Francesco Mannella; Marco Mirolli; Gianluca Baldassarre.
Goal-directed behaviours are defined by the presence of two kinds of effect on instrumental learning. First, degrading the contingencies between produced actions and desired outcomes diminishes the number of instrumental responses; second, devaluing a reward results in a lower production of instrumental actions to obtain it. We present a computational model of the neural processes underlying instrumental devaluation in rats. The model reproduces the interaction between the basolateral complex of the amygdala (BLA) and the limbic, associative and somatosensory striato-cortical loops. Firing-rate units are used to abstract the activity features of neural populations. Learning is reproduced through the use of dopamine-dependent simple and differential hebbian...

This Special Feature Volume examines the potential value of the Systems Approach Framework (SAF) as a methodological framework for the transition to sustainable development in coastal zones.  This article provides insight on the Systems Approach, the theory behind it, and how its practical application to coastal zone systems (CZSs) was developed.  The SAF is about information for management through a focus on how to generate a higher, dynamic level of information about complex CZSs and how to render this information more useful to end users through a participatory suite of communication methods. The SAF is an open research methodology that investigates the function of systems in order to simulate specific issues or questions concerning their function. The...

A Systems Biology Approach to the Evolution of Codon Use Pattern
Provedor de dados: 17
Autores: Ines Thiele; Ronan M. T. Fleming; Richard Que; Aarash Bordbar; Bernhard O. Palsson.
The genetic code is redundant as amino acids are encoded by synonymous codons that are unequally used.This codon usage bias (CUB) affects gene expression and cellular functions yet the underlying mechanisms have not been elucidated. We used a sequence-specific, stoichiometric model of metabolism and macromolecular synthesis for Escherichia coli K12 MG1655 to test the effect of randomly changed CUB on growth maximization under various environmental conditions. Amongst CUB mutant strains, we identified reduced growth phenotypes, which were caused by tRNA supply shortage. We propose, supported by computations and bibliomic data, that expansion of tRNA gene content or tRNA reading is a mechanism to respond to changes in CUB. Our systems biology modelling...

A Tale of Two Countries: Emissions Scenarios for China and India
Provedor de dados: 31
Autores: Massetti,   Emanuele.
The aim of the paper is to present evidence that China and India are, and will remain, two very different actors in international negotiations to control global warming. We base our conclusions on historical data and on scenarios until 2050. The Business-as-Usual scenario (BaU) is compared to four Emissions Tax scenarios to draw insights on major transformations in energy use and in energy supply and to assess the possible contribution of China and India to a future international climate architecture. We study whether or not the Copenhagen intensity targets require more action than the BaU scenario and we assess whether the emissions reductions induced by the four tax scenarios are compatible with the G8 and MEF pledge to reduce global emissions by 50% in...

A Tax Mix Change to Reduce Greenhouse Gas Emissions
Provedor de dados: 31
Autores: Freebairn,   John W.
Placing a price on greenhouse gas emissions using an emissions tax or auctioning tradable permits provide the least cost government intervention to reduce pollution. Initial effects of the charge on pollution include an increase in the relative prices of greenhouse gas intensive products and production processes to reduce pollution, and a net increase in indirect taxes with a windfall boost to government revenue. There are at least three overlapping sets of economic efficiency, equity and political acceptance reasons for returning most of the windfall revenue gains to households as compensating income tax reductions and increases in social security payments as a tax mix change package. Most of the indirect tax increases will be passed onto consumers as a...

Provedor de dados: 16
Autores: Maas, P.J.M.; Westra, L.Y.Th.
This paper deals with a group of species of the Neotropical genus Guatteria (Annonaceae) which are characterized by leaves with tiny warts (verruculae) on both surfaces and by elongate and short-stipitate monocarps (i.e., the length of the monocarp body surpassing the length of the stipe). These species were placed by Fries in Guatteria sect. Mecocarpus (Fries 1939) (the name derives from Ancient Greek μηκων = Poppy and καρπος = fruit: fruit resembling that of Papaver species). All occur in South America, none having been found elsewhere so far. Although there is much doubt nowadays about the taxonomic significance of Fries’s sections, we maintain sect. Mecocarpus at present for convenience’s sake. Additionally, the former genus Guatteriopsis, united with...

A Tisza-tó jelentős változásokat idézett elő a térség életében, módosult a települések térbeli kiterjedése. Ez a fajta térmódosulás a tanulmányban bemutatott ábrákon kiválóan végigkövethető. Sarud, Abádszalók és Tiszafüred esetében egyértelműen megállapítható, hogy a települések térszerkezetének eltolódása a Tisza-tó partján kínálkozó turisztikai lehetőségek hatására következett be. A településkép beépítettségében, új településrészek kialakításában, a település arculatának módosulásában szintén közrejátszott a Tisza-tó léte. A strandok településformáló hatása is jelentős a feléjük vezető lineáris infrastruktúrák fejlődésében, az út mentén lévő telkek árainak felértékelésében és a parton végbemenő változásokban (például Abádszalók).

Autores: Julia Hosp; Alexandra Ribarits; Katarzyna Szaszka; Yongfeng Jin; Alisher Tashpulatov; Marina Baumann; Tatiana Resch; Christina Friedmann; Elisabeth Ankele; Viktor Voronin; Klaus Palme; Alisher Touraev; Erwin Heberle-Bors.
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs). CRLs are activated through modification of the cullin subunit with the ubiquitin-like protein RUB/NEDD8 by an E3 ligase called defective in cullin neddylation 1 (DCN1). Here we show that tobacco DCN1 binds ubiquitin and RUB/NEDD8, and associates with cullin. When knocked down by RNAi, tobacco pollen formation stopped and zygotic embryogenesis was blocked around the globular stage. Additionally, we found that RNAi of DCN1 inhibited the stress-triggered reprogramming of cultured microspores from their intrinsic...

A Trade Area Analysis of Wisconsin Counties: Updated for 2010
Provedor de dados: 31
Autores: Deller,   Steven C.
For updated Trade Area Analysis (TAA) of Wisconsin counties we use the sales tax data as reported by the Wisconsin Department of Revenue for 2010. Only those counties that have elected to collect the optional county sales tax are included in the analysis. Because sales tax data are used one must keep in mind that the analysis focuses only on taxable sales and may not reflect the total level of activity in the county. Using Pull Factors and measures of Surplus and Leakage the relative strengths, and weaknesses, of local retail and service markets are identified. Changes in Pull Factors from 2005 to 2010 are provided to gain insights into growing and declining sectors. Finally, an update of simple Wisconsin retail market thresholds estimates (i.e., number of...

The identification of expressed genes involved in sexual precocity of the mitten crab (Eriocheir sinensis) is critical for a better understanding of its reproductive development. To this end, we constructed a cDNA library from the rapid developmental stage of testis of E. sinensis and sequenced 3,388 randomly picked clones. After processing, 2,990 high-quality expressed sequence tags (ESTs) were clustered into 2,415 unigenes including 307 contigs and 2,108 singlets, which were then compared to the NCBI non-redundant (nr) protein and nucleotide (nt) database for annotation with Blastx and Blastn, respectively. After further analysis, 922 unigenes were obtained with concrete annotations and 30 unigenes were found to have functions possibly related to the...

A transgenic rat model for reducing adult neurogenesis.
Provedor de dados: 17
Autores: Jason S. Snyder; Laura Grigereit; Michelle Brewer; Jim Pickel; Heather A. Cameron.
The function of adult neurogenesis remains unclear. While many tools for manipulating neurogenesis have been developed for mice, there are fewer tools for rats. Radiological and chemical strategies have been used to inhibit adult neurogenesis in rats but these methods may also have undesired side effects. Since rats have a larger brain and can perform complex behaviors, it would be useful to have additional rat models for studying neurogenesis. To address this gap we therefore developed a transgenic GFAP-TK rat in which adult neurogenesis can be specifically inhibited. Preliminary results suggest that, as in mice, reduced adult neurogenesis leads to anhedonia.

A Trend Deduction Model of Fluctuating Oil Prices
Provedor de dados: 31
Autores: Xu,   Haiyan; Zhang,   ZhongXiang.
Crude oil prices have been fluctuating over time and by a large range. It is the disorganization of oil price series that makes it difficult to deduce the changing trends of oil prices in the middle- and long-terms and predict their price levels in the short-term. Following a price-state classification and state transition analysis of changing oil prices from January 2004 to April 2010, this paper first verifies that the observed crude oil price series during the soaring period follow a Markov Chain. Next, the paper deduces the changing trends of oil prices by the limit probability of a Markov Chain. We then undertake a probability distribution analysis and find that the oil price series have a log-normality distribution. On this basis, we integrate the...

A two-step strategy for the complementation of M: tuberculosis mutants
Provedor de dados: 74
Autores: Movahedzadeh,Farahnaz; Frita,Rosangela; Gutka,Hiten J.
The sequence of Mycobacterium tuberculosis, completed in 1998, facilitated both the development of genomic tools, and the creation of a number of mycobacterial mutants. These mutants have a wide range of phenotypes, from attenuated to hypervirulent strains. These phenotypes must be confirmed, to rule out possible secondary mutations that may arise during the generation of mutant strains. This may occur during the amplification of target genes or during the generation of the mutation, thus constructing a complementation strain, which expresses the wild-type copy of the gene in the mutant strain, becomes necessary. In this study we have introduced a two-step strategy to construct complementation strains using the Ag85 promoter. We have constitutively...

Também nos leva a reconsiderar os princípios da governança neoliberal contemporânea, suas “racionalidades de governo”, tecnologias e aparatos, a maneira como estes trabalham para capturar tanto corações quanto mentes e ainda como promovem uma arte de governar “emocionalizada”, a ponto de podermos falar, apropriadamente, de “emocionalidades de governo”.

Magyarország csak a vidékgazdaság megfelelő működtetésével lehet eredményes. A vidék az átalakulás időszakában elvesztette népességmegtartó képességét. Ennek a folyamatnak a megállításához új irányok meghatározása aszükséges. A cikk az új fejlesztési irányok meghatározására tesz kísérletet. --------------------------------------------- Hungary can be sxuccesssfull only if the rural areas are viable. In the alst decades the rural areas have lost a grat part of their population. To stop this process new rural development strategy is needed. The paper focus on new potential development directions.

A Whole Farm Analysis of the Influence of Auto-Steer Navigation on Net Returns, Risk, and Production Practices
Provedor de dados: 31
Autores: Shockley,   Jordan M.; Dillon,   Carl R.; Stombaugh,   Timothy S.
A whole farm economic analysis was conducted to provide a detailed assessment into the economic, risk, and production implications due to the adoption of auto-steer navigation. It was determined that auto-steer navigation was profitable for a grain farmer in Kentucky with net returns increasing up to 0.90% ($3.35/acre). Additionally, the technology could be used in reducing production risk. Adoption of the technology also alters production practices for optimal use.

A whole farm comparison of irrigated cotton rotations in the Lower Namoi Valley, NSW
Provedor de dados: 31
Autores: Powell,   Janine; Scott,   J. Fiona.
A whole farm budget for a representative farm in the Lower Namoi Valley in northern NSW was used to analyse the financial implications of a comparative rotational experiment of four cotton-based rotations conducted in recent years at the Australian Cotton Research Institute, near Narrabri. The model was used to compare the rotations, which highlighted the importance of crop selection for the financial performance of the business. Apart from providing a broad brush picture of financial performance, the model also had a stochastic component which was used to analyse the effect of variable commodity prices on the whole farm profitability of each rotation. Mean results indicated a positive return for all rotations within the representative farm budgets for the...

Autores: Döring, Thomas F.; Crowley, Oliver; Pearce, Helen; Storkey, Jonathan; Brown, Rob; Jones, Hannah.
The inter-relationship between food production and biodiversity is now well established. The ecosystem services provided by the organisms within the environment include, for example, nutrient cycling, pest regulation and pollination, to name but a few. However, perhaps the greatest challenge now facing agricultural production is to find ways of enhancing these ecosystem services, while at the same time increasing food production – particularly in light of food security issues. A range of farm and landscape management options include ‘setting aside’ land for wildlife. However, some proponents argue that such land should be used for food production. While the debate continues, there is no doubt that a large body of scientific evidence from the last three...

Autores: Paull, John; Hennig, Benjamin.
This paper presents a world map of organic agriculture. A Gall-Peters projection map of the world is taken as the reference map (where map areas are proportional to territorial areas). Applying the area of organic agriculture to countries, the World Map of Organic Agriculture presents countries as proportional in size to their share of the total of world organic hectares (such a map can be referred to as an equal-area cartogram or a densityequalising  map). The World Map of Organic Agriculture accounts for 37.2 million hectares of organically managed agricultural land (certified organic and in-conversion organic) from 160 countries, and here distributed across the 200 territories of the reference map.

Aardbeien: uitdaging voor de  biologische teler
Provedor de dados: 21
Autores: van Hamont, Jos.
Biologische aardbeien worden nog maar weinig geteeld. De voornaamste reden hiervoor is dat de teelt niet zo gemakkelijk is en er nogal wat kan misgaan. Ook vraagt de aardbeienteelt een aanzienlijke hoeveelheid arbeid, waardoor het relatief duur is. Het aanbod biologische aardbeien is dus gering. Ook zijn  de groothandelsbedrijven voorzichtig met inkopen, hetgeen potentiële telers verder afremt. Een continu aanbod ontbreekt dus: hoog tijd om de cirkel te  doorbreken en de continuïteit te verbeteren. In dit BioKennisbericht meer over de biologische teelt van aardbeien.

Abatement Technology and the Environment-Growth Nexus with Education
Provedor de dados: 31
Autores: Pautrel,   Xavier.
This article challenges the conventional result that a tighter environmental tax has no long-run effect on human capital accumulation in the presence of pollution arising from final output production. It demonstrates that the technology used in the abatement sector determines the existence and the direction of the growth-effect. A tighter environmental tax rises (respectively reduces) human capital accumulation in the presence of pollution arising from final production, if the abatement sector is relatively more intensive in human (resp. physical) capital than final sector. That result always holds for finite lifetime but for infinite lifetime it only holds when labor supply is endogenous. The transitional impact of a tighter environmental policy is also...

ABC Methods for Bayesian Model Choice
Provedor de dados: 17
Autores: Christian P. Robert.
Approximate Bayesian computation (ABC), also known as likelihood-free  methods, have become a standard tool for the analysis of complex models, primarily in population genetics but also for complex financial models. The development of new ABC methodology is undergoing a rapid increase in the past years, as shown by multiple publications, conferences and even software. While one valid interpretation of ABC based estimation is connected with nonparametrics, the setting is quite different for model choice issues. We examined in Grelaud et al. (2009, Bayesian Analysis) the use of ABC for Bayesian model choice in the specific of Gaussian random fields (GRF), relying on a sufficient property only enjoyed by GRFs to show that the approach was legitimate. Despite...

Autores: Tina Toni.
Approximate Bayesian Computation (ABC) methods can be used in situations where the evaluation of the likelihood is computationally prohibitive. They are thus ideally suited for analyzing the complex dynamical models encountered in systems biology, where knowledge of the full (approximate) posterior is often essential.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;This talk gives an overview of an ABC algorithm based on Sequential Monte Carlo (ABC SMC). Different uses of the algorithm will be presented, depending on the application question of interest. The first is the general parameter estimation framework, where the interest lies in estimating the posterior parameter distribution from available experimental data. In the second context we ask whether the model can...

Previous studies have demonstrated that river-based surveys can provide an inexpensive source of information for neotropical zoologists, yet little information is available to inform the application of this technique for the long term monitoring of neotropical turtle species. We aimed to fill this gap by presenting an assessment of data collected during 333 river surveys over 50 months along rivers in a newly protected area in the Peruvian Amazon. A total of 14,138 basking Podocnemis unifilis Troschel, 1848 were recorded during 13,510 km of river-based surveys. We used generalized additive models (GAMs) to explore the influence of a series of abiotic and seasonal variables on the recorded abundances at two temporal scales: monthly and per trip. Our...

Las evidencias encontradas en Perú y México señalan que la oferta profesional se halla estratificada, lo que otorga a los sectores sociales mejor situados una mejor calidad disponible. Es por eso que quienes tienen mayor poder pueden reforzarlo con el concurso de mejores abogados, en tanto que quienes poseen menor poder se hallan desprotegidos en términos de defensa profesional.

Potential historical temporal trends in monthly, seasonal, and annual mean, minimum, and maximum streamflows and date of the spring freshet runoff peak were investigated for the Okanagan and Similkameen Rivers in south-central British Columbia, Canada. There appears to be no compelling evidence that streamflow patterns in the Okanagan and Similkameen Rivers have changed over the available hydrometric record, nor does there appear to be evidence that future changes in streamflow patterns are imminent or likely.

Absence of occult hepatitis B among blood donors in southern Brazil
Provedor de dados: 55
Autores: Wolff,Fernando Herz; Fuchs,Sandra Costa; Brandão,Ajacio BM.
BACKGROUND: Occult hepatitis B virus (HBV) infection is characterized by the detection of HBV DNA in serum and/or in liver in the absence of detectable hepatitis B surface antigen (HBsAg). The reported prevalence of occult hepatitis B varies markedly among populations and according to the sensitivity of the HBV DNA assay. The aim of the present study was to describe the prevalence of occult hepatitis B among HCV-infected and non-infected blood donors in Porto Alegre, Southern Brazil, using a highly sensitive real time polymerase chain reaction (PCR) method. METHODOLOGY: Between 1995 and 1997 a sample of 178 blood donors with two positive anti-HCV ELISA tests were consecutively selected as cases, and 356 anti-HCV negative donors were selected as controls....

Autores: Andrade,Gabriel José Massoni de; Rosolem,Ciro Antonio.
Foi levantada a hipótese de que o glifosate aplicado à soja resistente ao herbicida poderia alterar a eficiência de absorção e translocação do nutriente na planta. Com o objetivo de estudar o acúmulo e distribuição do Mn, assim como a cinética de absorção de Mn pela soja geneticamente modificada sob efeito da aplicação de glifosate, foram conduzidos dois experimentos. No primeiro, os tratamentos foram constituídos por duas cultivares de soja quase isogênicas cultivadas em solução nutritiva (Conquista e Valiosa RR com aplicação ou não do herbicida). As concentrações de Mn empregadas na solução nutritiva foram: 0; 0,085; 0,125; 0,250; e 0,500 mg L-1. Após 25 dias de cultivo, parte do total de plantas de soja transgênica foi pulverizada com o herbicida. No...

Absorção de nutrientes e crescimento do arroz com suprimento combinado de amônio e nitrato¹
Provedor de dados: 90
Autores: Holzschuh,Marquel Jonas; Bohnen,Humberto; Anghinoni,Ibanor; Pizzolato,Tânia Mara; Carmona,Felipe de Campos; Carlos,Filipe Selau.
O arroz é classificado como uma planta tolerante ao amônio (NH4+) devido à predominância desse íon nos solos alagados. Entretanto, nas regiões oxidadas do solo e da rizosfera do arroz pode haver a formação de nitrato (NO3-) e esta se tornar importante fonte de N para cultura. Este trabalho foi conduzido com o objetivo de avaliar o efeito de diferentes proporções entre os íons NH4+ e NO3- no desenvolvimento do arroz em solução nutritiva. O experimento foi realizado em casa de vegetação no período de janeiro a fevereiro de 2008, em solução nutritiva com as seguintes proporções entre NH4+ e NO3-: 100:0, 75:25, 50:50, 25:75 e 0:100 na concentração de 5,0 mmol L-1 de N.

Provedor de dados: 75
Autores: Souza,Rovilson José de; Macêdo,Fábio S; Carvalho,Janice G de; Santos,Bruno R; Leite,Leandra Vicentina dos R.
Nos últimos anos, verificou-se significativa elevação na produtividade e qualidade do alho cultivado no Brasil. Dentre os fatores que proporcionaram este resultado pode-se citar o uso de cultivares nobres, da vernalização e da utilização de alho-semente livres de vírus. Entretanto, poucos são os estudos realizados visando avaliar o crescimento e a absorção de nutrientes em cultivares de alho nobre vernalizadas, provenientes de cultura de meristemas, altamente produtivas em relação às cultivares de alho comum. O objetivo deste trabalho foi determinar a marcha de absorção de nutrientes em alho vernalizado proveniente de cultura de meristemas em função de diferentes doses de N aplicadas em cobertura. Os tratamentos consistiram de cinco doses de N aplicadas em...

Absorción de antígenos solubles ABH por larvas de Ascaris lumbricoides in vitro
Provedor de dados: 38
Autores: Ponce de León,Patricia; Di Vita,Santiago; Biondi,Claudia; Valverde,Juana.
En investigaciones previas se identificaron antígenos ABH en ejemplares adultos de Ascaris lumbricoides. Los parásitos sólo presentaron epitopes expresados en sus respectivos hospedadores, adquiridos por absorción. Como el parásito adulto vive en el intestino delgado, podría presentarlos debido a que la larva de cuarto estadio conserva los epitopes absorbidos en la migración y los mantiene durante el proceso madurativo a adulto o bien el ejemplar adulto los adquiriría de las secreciones intestinales. El objetivo fue estudiar la absorción de epitopes solubles ABH por larvas mantenidas en cultivo. Las larvas fueron obtenidas de la eclosión de huevos y se recolectaron y cultivaron en medio RPMI. Se adicionó antígeno soluble B en tres tubos que fueron...

Abundance and activity patterns of the margay (Leopardus wiedii) at a mid-elevation site in the Eastern Andes of Ecuador
Provedor de dados: 81
Autores: Vanderhoff,E. Natasha; Hodge,Anne-Marie; Arbogast,Brian S.; Nilsson,Jonas; Knowles,Travis W.
We investigated abundance and activity patterns of the margay (Leopardus wiedii) via remote camera-trapping at Wildsumaco Wildlife Sanctuary, a new preserve located near Sumaco National Park, in the eastern Andean foothills of Ecuador. We recorded 85 capture events and ten individuals, including one juvenile, over a total of 3220 camera-trap nights. Activity was mostly nocturnal and we found no difference in abundance between primary and secondary forest. Our capture rate (2.64 captures/100 camera-trap nights) indicates a high abundance of margays in the region. The site lies within a matrix of agricultural lands and the high abundance and seasonal occurrence data seem to suggest that while one or two females may occupy the area permanently, most margays...

Abundance and diversity of Planctomycetes in a Tyrrhenian coastal system of central Italy
Provedor de dados: 5
Autores: Pizzetti, Ilaria; Gobet, Angelique; Fuchs, Bernhard M.; Amann, Rudolf; Fazi, Stefano.
The phylum Planctomycetes is involved in important processes, such as the mineralization of algal biomass and the removal of nitrogen. Using a combination of 16S rRNA sequence analysis and in situ hybridization, we analyzed the diversity and dynamics of Planctomycetes in a shallow meso-eutrophic lake, Lago di Paola, Italy. Planctomycetes detected by the probe PLA46 accounted for 1 to 5% of prokaryotic picoplankton. Abundances were higher in the coastal lake than in the adjacent marine waters. In the surface waters of the lake, the numbers of Planctomycetes fluctuated greatly, reaching a maximum of 1.5 x 10(6) cells ml(-1) in July. The hypoxic bottom waters had less variable cell abundances. The Planctomycetes counts were positively correlated with...

Abundance and diversity patterns of the sessile macrobenthic community associated with environmental gradients in Vitória Harbor, southeastern Brazil
Provedor de dados: 103
Autores: Zalmon,Ilana Rosental; Krohling,Werther; Ferreira,Carlos Eduardo Leite.
Harbor terminals and urban sewage effluents affect the composition and distribution of epibenthic organisms. In this study, we hypothesized that the benthic community structure at the Vitoria Harbor changes spatially in a ~3 km scale, and that these changes are associated with environmental gradients resulting from point-source sewage and differences in the physical and chemical parameters of the water along the harbor access channel. Four sites, internal (PI), intermediate-internal (PMI), intermediate-external (PME) and external (PE), varying from 0.5 to 4.0 km off the harbor, were sampled on five quadrats at six sampling dates (N = 30 per site). The epibenthic community on the shallow sublitoral rocky shore was sampled fortnightly from December 2005 to...

Abundance of bottlenose dolphins, Tursiops truncatus (Cetacea: Delphinidae), inhabiting the Patos Lagoon estuary, southern Brazil: implications for conservation
Provedor de dados: 103
Autores: Fruet,Pedro F; Secchi,Eduardo R; Di Tullio,Juliana C; Kinas,Paul G.
A new mark-recapture abundance estimate and a photographic census were carried out to investigate the possible decline in the abundance of the bottlenose dolphins, Tursiops truncatus (Montagu, 1821), in the Patos Lagoon estuary due to the high levels of bycatch mortality which occurred between 2002 and 2006 in oceanic coastal areas close to the estuary. Fourteen systematic boat surveys were conducted between August and early December 2005 to photo-identify the bottlenose dolphins. The estimated number of animals, with long-lasting marks, in the population obtained from Chapman's and Mth models were 51 (95% CI = 49-53) and 52 (95% CI = 51-60), respectively. Taking into account the proportion of dolphins with long-lasting marks in the population, the total...

Abundância e diversidade de palmeiras no Distrito Florestal Sustentável da rodovia BR-163, Pará, Brasil
Provedor de dados: 49
Autores: Salm,Rodolfo; Jardim,Mário Augusto Gonçalves; Albernaz,Ana Luisa Kerti Mangabeira.
A abundância e a diversidade de espécies, bem como a relação com a estrutura da floresta foram investigadas no Distrito Florestal Sustentável (DFS) da rodovia BR-163. Foram estabelecidas 40 parcelas de 0,04 ha (20 × 20 m) em uma mata prístina no Parque Nacional (PARNA) da Amazônia e 40 parcelas semelhantes em uma área submetida à exploração madeireira na Floresta Nacional do Tapajós. Em cada parcela, as árvores com DAP ≥ 10 cm foram medidas e as palmeiras adultas identificadas e contadas. Foi verificado que, apesar da floresta explorada da FLONA do Tapajós ser estruturalmente mais aberta que a mata do PARNA, apresenta menor quantidade e menor diversidade de espécies, provavelmente devido às limitações da dispersão de frutos e sementes e pela recente...

Acanthifoliosides, minor steroidal saponins from the Caribbean marine sponge Pandaros acanthifolium
Provedor de dados: 20
Autores: Regalado, E.L.; Jiménez-Romero, C.; Genta-Jouve, G.; Tasdemir, D.; Amade, P.; Nogueiras, C.; Thomas, O.P.
Seven novel steroid glycosides, acanthifoliosides A-F (1-6) and the methyl ester of 6 (7), were isolated from the marine sponge Pandaros acanthifolium as minor components. Acanthifoliosides are characterized by a rare C-15 and C-16 oxidized D ring which was previously found in saponins produced by starfishes. Very uncommon is the presence of additional sugar residues at C-15 or C-16. Their structures were determined on the basis of extensive spectroscopic analyses, including two-dimensional NMR and HRESIMS data. The absolute configurations of the aglycones were assigned by comparison between experimental and TDDFT calculated CD spectra of 1, whereas the absolute configurations of the monosaccharide units were determined by chiral GC analyses of the acid...

Enzimas extracelulares de fungos são importantes para sua sobrevivência em ambientes inóspitos, sendo capazes de degradar compostos recalcitrantes. Fungos filamentosos secretam hidrolases e fenoloxidases capazes de degradar complexos de estruturas aromáticas, como de alguns xenobióticos. O propósito deste trabalho foi testar diferentes corantes (Azul de Metileno, Azure B, Verde Malaquita e Cristal Violeta), em substituição ao composto Poly R478, no método de seleção de microrganismos degradadores de fenóis em meio sólido, além de comparar tal atividade de Micoflora isolada de efluentes de indústria sucroalcooleira com a de outros fungos adquiridos em coleção oficial. Os corantes testados revelaram-se ótimos substitutos do Poly R478. O isolado que...

A ordem Isoptera é bastante conhecida pelo seu potencial como praga, apesar dos cupins-praga constituírem a minoria dentro do grupo. Os cupins (térmitas) são invertebrados dominantes em ambientes terrestres tropicais e estão espalhados desde as florestas úmidas até as savanas, sendo encontrados até mesmo em regiões áridas, nos mais variados habitats. Esses insetos têm um papel destacado e ainda pouco estudado nos ecossistemas tropicais. Ciclagem de nutrientes, aeração, infiltração de água do solo, bioturbação, formação de agregados e decomposição de material orgânico, são processos influenciados pela ação dos térmitas, que vão, direta ou indiretamente, influenciar a formação dos solos e da paisagem onde se encontram. Sugerimos que uma maior abordagem deva...

Parasite infections caused by Rhipicephalus (Boophilus) microplus are responsible for the most of economic losses in producing-cattle countries in tropical and subtropical areas. Indiscriminate uses of chemical acaricides have contributed with the appearance of tick resistance to many drugs available in the marketplace, and it is a serious problem in the tick control. Flowers of Sambucus australis (South America), called "sabugueiro-from-Brazil", are used on infusions or decoctions forms in the folk medicine with diuretic, antipyretic, anti-inflammatory, and laxative purpose, also employed for treating respiratory diseases in human. The main goal of this study was to evaluate in vitro potential of S. australis leaves extracts as an acaricide agent. Ethanol...

Autores: Romo Evaristo, Marisol.
En la actualidad la situación de degradación de los recursos naturales, en especial el recurso bosque, ocasiona la pérdida tanto de identidad de la población que dependen de estos recursos, como de la misma flora y fauna del lugar, además que la introducción de la tecnología moderna y las formas de producción añadidos con el consumismo, han favorecido la destrucción del ambiente natural, siendo la sociedad humana una de las principales causas de dicha degradación. Aunado a ello, desde los 80s, se enfatizó que las mujeres fueron las principales víctimas del deterioro ambiental, además de catalogarlas como adaptadas para soportar catástrofes como las sequias, y se consideraban víctimas del deterioro ambiental, de los procesos científicos y de desarrollo mal...

Access to Microfinance: Does it Matter for Profit Efficiency Among Small Scale Rice Farmers in Bangladesh?
Provedor de dados: 31
Autores: Sumelius,   John; Islam,   K.M. Zahidul; Sipilainen,   Timo.
This paper measures profit efficiency and examines the effect of access to microfinance on the performance of rice firms in Bangladesh. An extended Cobb-Douglas stochastic frontier profit function was used to assess profit efficiency and profit loss of rice farmers in Bangladesh in a survey data of 360 farms throughout the 2008-2009 growing seasons. Model diagnostics reveal that serious selection bias exists that justifies the uses of sample selection model in stochastic frontier models. After effectively correcting for selectivity bias, the mean profit efficiency of the microfinance borrowers and non-borrowers were estimated at 68% and 52% respectively, thereby suggesting that a considerable share of profits were lost due to profit inefficiencies in rice...

Accidents Happen: The Effect of Uncertainty on Environmental Policy Design
Provedor de dados: 31
Autores: Sproul,   Thomas W.; Zilberman,   David.
Major externality cases are random accidents which are not adequately addressed by the deterministic environmental policy literature -­‐ that of Pigouvian taxes, abatement subsidies and cap-­‐and-­‐trade. We consider a risk-­‐neutral industry where firms control the probability and Severity of accidents by preventive and responsive choices, but asymmetric information means Government only observes outcomes. We show that even without intervention, some care will be taken, however -­‐ we identify three policies that lead to the optimal solution: strict liability, a Stochastic subsidy, and a mandatory mutual insurance scheme. The subsidy policy may be very costly to taxpayers, especially when prevention affects the probability of accident occurrence, and...

Autores: Oliveira,João Ricardo Gonçalves de; Morais,Thiago Alberto de Lima; Melo,Natoniel Franklin de; Yano‑Melo,Adriana Mayumi.
The objective of this work was to assess the potential of three isolates of arbuscular mycorrhizal fungi to promote growth of micropropagated plantlets of Tapeinochilos ananassae during acclimatization. The experiment was carried out in greenhouse, in a completely randomized block design, with four inoculation treatments: non‑inoculated control and plants inoculated with Glomus etunicatum, Acaulospora longula or Gigaspora albida, with ten replicates. After 90 days, the following parameters were evaluated: survival rate, height, leaf and tiller number, leaf area, fresh and dry biomass, contents of macro‑ and micronutrients in the root and shoot, glomerospore number, and mycorrhizal colonization. The survival percentage was 100%, except for plants inoculated...

Autores: May, Bradley; Adaptation and Impacts Research Section, Environment Canada; Bradley.May@ec.gc.ca; Plummer, Ryan; Brock University, Canada; Stockholm Resilience Centre, Stockholm University; ryan.plummer@brocku.ca.
Risk management is a well established tool for climate change adaptation. It is facing new challenges with the end of climate stationarity and the need to meaningfully engage people in governance issues. The ways in which conventional approaches to risk management can respond to these challenges are explored. Conventional approaches to risk management are summarized, the manner in which they are being advanced as a tool for climate change adaptation is described, and emerging themes in risk management and climate change adaption are documented. It is argued that conventional risk management for climate change adaptation can benefit from the insights and experiences of adaptive co-management. A hybrid approach termed adaptive collaborative risk management...

Accounting for agronomic rotations in crop production: A theoretical investigation and an empirical modeling framework
Provedor de dados: 31
Autores: Carpentier,   Alain; Gohin,   Alexandre; Letort,   Elodie.
As far as crop acreage choices are concerned, a consensus seems to exist among agricultural scientists and extension agents: crop rotation effects and the related constraints are major determinants of farmers’ crop choices. Crop rotation effects are inherently dynamic. They are generally ignored in multicrop models with land as an allocable input found in the literature since most of these models are developed within a static framework. The aim of this paper is twofold (i) to propose a new approach and tools for investigating dynamic crop acreage choices accounting for crop rotation benefits and constraints and (ii) to illustrate the impacts of crop rotation effects and constraints on farmers’ acreage choices through simulation examples. The models...

Autores: Othman,   Jamal; Jafari,   Yaghoob.
This paper provides an assessment of the changes in the availability of oil and gas resources in Malaysia. The physical and monetary balance sheets for crude oil and natural gas for the period 2000- 2007 was constructed. The net present value of expected future incomes to reflect the value of resource change was calculated based on a physical extraction and a resource rent scenario. Resource rent is gross operating surplus less the estimated user cost of produced capital in the crude oil and natural gas extraction industry. We obtained the gross operating surplus by subtracting the value of consumption of employees and net taxes on production cost from the value added of petroleum domestic products. Our findings noted serious reduction of oil reserves from...

Accounting for Heterogeneity in Hedging Behavior: Comparing &amp; Evaluating Grouping Methods
Provedor de dados: 31
Autores: Pennings,   Joost M.E.; Garcia,   Philip; Irwin,   Scott H.
Heterogeneity, i.e., the notion that individuals respond differently to economic stimuli, can have profound consequences for the interpretation of behavior and the formulation of agricultural policy. This paper compares and evaluates three grouping techniques that can be used to account for heterogeneity in financial behavior. Two are well established: company-type grouping and cluster analysis. A third, the generalized mixture regression model, has recently been developed and is worth considering as market participants are grouped such that their response to the determinants of economic behavior is similar. We evaluate the grouping methods in a hedging framework by assessing their ability to reflect relationships consistent with theory. The empirical...

Autores: Viaggi,   Davide; Raggi,   Meri; Sardonini,   Laura.
In evaluating the potential effects of the reforms of the Common Agricultural Policy, a particularly challenging issue is the representation of the complexity of rural systems either in a static or dynamic framework. In this paper we use Bayesian networks, to the best knowledge of the authors, basically ignored by the literature on rural development. The objective of this paper is to discuss the potential use of Bayesian Networks tools to represent the multiple determinants and impacts of the Common Agricultural Policies in rural areas across Europe. The analysis shows the potential use of BNs in terms of representation of the multiple linkages between different components of rural areas and farming systems, though its use as a simulation tool still...

Accounting for Product Substitution in the Analysis of Food Taxes Targeting Obesity
Provedor de dados: 31
Autores: Miao,   Zhen; Beghin,   John C.; Jensen,   Helen H.
We extend the existing literature on food taxes targeting obesity. First, we incorporate the implicit substitution between sugar and fat nutrients implied by a complete food demand system and by conditioning on how food taxes affect total calorie intake. Second, we propose a methodology that accounts for the ability of consumers to substitute leaner low-fat and low-sugar items for rich food items within the same food group. This substitution is integrated into a demand system in addition to substitution among food groups. Simulations of a tax on added sugars show that the impact of the tax on consumption patterns is understated and the effect on welfare loss overstated when abstracting from this substitution within food groups.

Accounting for Social Spending Escalation in Rural China

Autores: Chen,   Xi.
It has been widely recognized that the poor spends a significant proportion of their  income on social spending even at the expense of basic consumption. What are the  motives behind the observed lavish social spending among the poor? We attempt to  test three competing explanations at the social link level, risk pooling, peer effect, and  status concern, via a uniform framework based on a unique primary dataset. The data  set include household information from a three wave census type household survey as  well as a long term gift record for all households in three villages in a poor region in  rural China.  Our dyadic estimations confirm the prevalence of peer influence and the  status seeking motive in shaping gift spending and its rapid growth, while...

Two apricot genotypes, 'Gonci magyarkajszi' and 'Preventa' were assayed at three ripening stages for flesh color indices (L*, a*, b*, C* and Hº), contents of total phenolics and vitamin C, and both water- and lipid-soluble antioxidant capacities (ferric reducing antioxidant power; 2,2'-diphenyl-1-picrylhydrazyl scavenging activity; total radical scavenging activity; and Photochem lipid-soluble antioxidant capacity) to compare their dynamics in the accumulation of antioxidant compounds and capacities through ripening. The increase in a*, b* and C* and decrease in Hº during ripening represented a color shift from green to yellow and orange due to carotenoid accumulation. Parallel to carotenoid accumulation, contents of total phenolics and vitamin C and...

Accumulation of DOC in Low Phosphate Low Chlorophyll (LPLC) area: is it related to higher production under high N:P ratio?
Provedor de dados: 5
Autores: Mauriac, R.; Moutin, T.; Baklouti, M.
The biogeochemistry of carbon and nutrients (N,P) in the surface layer of the ocean strongly depends on the complex interactions between primary producers (phytoplankton) and remineralizers (heterotrophic bacteria). To understand how these interactions impact the overall DOC dynamics in the surface layer of the Mediterranean Sea, we implemented, using Eco3M (Ecological Mechanistic Modular Modelling tool), a multi-element model with a mechanistic description of primary production. We studied the model steady state results under various nutrient conditions and fixed cell abundances. By doing so, we show how the bottom up control of osmotrophs growth can impact the overall DOC dynamics in the system. Based on our set of parameters, the biogeochemical...

Although it has been known that the seed's physiological potential affects its response to osmoconditioning and abiotic stresses, researches involving seed aging and priming associated to abiotic stresses are scarce. The aim of this work was to evaluate the role of seed priming on salt tolerance in sorghum seedlings from seeds with two vigor levels (aged or non-aged) and to verify the organic and inorganic solute contributions as osmoregulators in NaCl-stressed seedlings from aged and primed seeds. The combinations of two seed vigor levels (aged or not), two seed types (primed or not) and two salinity levels (exposed to NaCl at 100 mM or not) were evaluated. In low physiological quality seeds (aged seeds), priming provided an attenuation of salinity's...

Accurate estimation of homologue-specific DNA concentration-ratios in cancer samples allows long-range haplotyping
Provedor de dados: 17
Autores: Scott L. Carter; Matthew Meyerson; Gad Getz.
Interpretation of allelic copy measurements at polymorphic markers in cancer samples presents distinctive challenges and opportunities. Due to frequent gross chromosomal alterations occurring in cancer (aneuploidy), many genomic regions are present at homologous-allele imbalance. Within such regions, the unequal contribution of alleles at heterozygous markers allows for direct phasing of the haplotype derived from each individual parent. In addition, genome-wide estimates of homologue specific copy- ratios (HSCRs) are important for interpretation of the cancer genome in terms of fixed integral copy-numbers. We describe HAPSEG, a probabilistic method to interpret bi- allelic marker data in cancer samples. HAPSEG operates by partitioning the genome into...

Based on molecular clock hypothesis, and neutral theory of molecular evolution, molecular phylogenies have been widely used for inferring evolutionary history of organisms and individual genes. Traditionally, alignments and phylogeny trees of proteins and their coding DNA sequences are constructed separately, thus often different conclusions were drawn. Here we present a new strategy for sequence alignment and phylogenetic tree reconstruction, codon and amino acid unified sequence alignment (CAUSA), which aligns DNA and protein sequences and draw phylogenetic trees in a unified manner. We demonstrated that CAUSA improves both the accuracy of multiple sequence alignments and phylogenetic trees by solving a variety of molecular evolutionary problems in...

Autores: Surek,Diego; Maiorka,Alex; Oliveira,Simone Gisele de; Dahlke,Fabiano; Krabbe,Everton Luis.
O experimento foi conduzido com o objetivo de avaliar o efeito da inclusão de ácido linoléico conjugado (CLA) em dietas de suínos dos 65kg de peso vivo até a fase de abate (100kg) sobre desempenho zootécnico, rendimento de corte e características de carcaça. Foram utilizados 200 suínos provenientes do cruzamento industrial JSR x PIC, em igual proporção de sexo. Os tratamentos foram compostos por dietas com (+CLA) e sem (-CLA) adição de CLA. O delineamento experimental utilizado foi completamente casualizado, sendo as características de carcaça avaliadas em esquema fatorial 2x2 (dieta x sexo). Os animais que consumiram CLA apresentaram melhor ganho de peso diário, redução da espessura de toucinho e maior rendimento de carne magra. A retenção de líquidos da...

Provedor de dados: 91
Autores: Carvalho,Fabricio E. L.; Lobo,Ana K. M.; Bonifacio,Aurenivia; Martins,Marcio O.; Lima Neto,Milton C.; Silveira,Joaquim A. G.
Estudou-se o efeito da aplicação exógena de peróxido de hidrogênio (H2O2) na aclimatação ao estresse salino com base nas alterações fotossintéticas, indicadores de estresse oxidativo e atividade de enzimas antioxidativas em folhas de plantas de arroz. Utilizaram-se duas diferentes concentrações de H2O2 (1 e 10 μM) para o pré-tratamento, concentrações essas aplicadas na solução nutritiva dois dias antes da indução do estresse salino (100 μM de NaCl). A limitação fotossintética e estomática resultante da exposição ao NaCl foi amenizada quando as plantas foram pré-tratadas com 1 μM de H2O2. Plantas expostas ao pré-tratamento com H2O2 e expostas ao NaCl apresentaram dano de membrana menor quando comparadas com as plantas submetidas ao NaCl isoladamente. O...

Autores: BALBINO, L. C.; MARTINEZ, G. B.; GALERANI, P. R.
Na iLPF os sistemas agrossilvipastoris, ao associar o componente árboreo às pastagens e às lavouras, adquirem importância, principalmente em regiões agropastoris com grande fragmentação de remanescentes florestais naturais e/ou com pastagens degradadas. A inclusão do componente árboreo ao da lavoura e da pastagem representa um avanço inovador da Integração Lavoura-Pecuária (iLP), evoluindo para o conceito de integração-Lavoura-Pecuária-Floresta (iLPF), estratégia de produção sustentável que integra atividades agrícolas, pecuárias e florestais, realizadas na mesma área, num cultivo consorciado, em sucessão ou rotação, buscando efeitos sinérgicos entre os componentes do agroecossistema, em busca da adequação ambiental, da valorização do homem e da...

Some handling practices related to health about finfish culture are analyzed and  discussed in this paper. The wild caught broodstocks were cultivated for two years  under environment conditions in concrete pond where developed techniques  avoided  stressful conditions like high stocking densities which may result in  compromised fish health, disease and mortality. Marine fish species are also  susceptible to many infectious pathogens including parasites. As a result of that,  prophylactic bathes have been identified as method of control. Reproductive  parameters could have showed due to good managements.

An Acoustic Doppler Current Profiler (ADCP) was moored at the deep-sea site of the ANTARES neutrino telescope near Toulon, France, thus providing a unique opportunity to compare high-resolution acoustic and optical observations between 70 and 170 m above the sea bed at 2475 m. The ADCP measured downward vertical currents of magnitudes up to 0.03 m s(-1) in late winter and early spring 2006. In the same period, observations were made of enhanced levels of acoustic reflection, interpreted as suspended particles including zooplankton, by a factor of about 10 and of horizontal currents reaching 0.35 m s(-1). These observations coincided with high light levels detected by the telescope, interpreted as increased bioluminescence. During winter 2006 deep...

Acrosin release and acrosin activity during incubation in capacitating media using fresh and frozen-thawed dog sperm
Provedor de dados: 48
Autores: de los Reyes,Mónica; Palomino,Jaime; Martínez,Víctor; Aretio,Carolina; Gutiérrez,Michel.
We evaluated the effect of time and temperature on acrosin release from the acrosomal cap and the activity of this enzyme during in vitro capacitation in fresh and frozen/thawed dog sperm. Sperm-rich fractions of six ejaculates from three dogs were processed as fresh and frozen samples. Each sperm sample was incubated in canine capacitation medium (CCM) for 0, 1, 2 and 3 h at 20°C and at 37°C. After incubation, the samples were assessed by the indirect immunofluorescent staining technique. The probability of having unlabeled sperm (PUS), indicating acrosin loss, was modelled by a binomial distribution using logistic regression. There was a linear relationship between PUS and time at both temperatures (p&lt;0.001); however, a major percentage of unlabeled...

An integrated approach using biomarkers and contaminant levels in mussels Mytilus galloprovincialis L was employed to assess chemical contamination in Greek coastal waters within the framework of the MYTIMED program. Biomarkers (metallothioneins, glutathione S-transferase, catalase, acetylcholinesterase and RNA:DNA ratio) have been previously described in mussels caged at 14 sites in coastal areas influenced by different types of anthropogenic activities. This study applied a biomarker index, the Integrated Biomarker Response (IBR) to summarize biomarker responses and relate stress levels to concentrations of organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs), and metals (Cu, Ni, Fe, Zn) measured in the mussel tissues. The IBR...

Dentro de las 7 que exhibieron actividad, 2 se seleccionaron para estudios complementarios y se identificaron por métodos fenotípicos y genotípicos como Enterococcus mundtii Tw 56 y Lactococcus lactis subsp. lactis Tw 34. Después de la neutralización con NaOH y tratamiento térmico (100 ºC y 121 ºC durante 5 min) la actividad antagonista del sobrenadante libre de células se mantuvo activa. El tratamiento con lisozima, lipasa y catalasa no afectó la actividad antimicrobiana. Sin embargo, la actividad enzimática de la tripsina suprimió la acción inhibitoria del sobrenadante, confirmando...

Activity level, emission intensity, and optimal GHG abatement policy: An application to Norwegian agriculture
Provedor de dados: 31
Autores: Blandford,   David; Gaasland,   Ivar; Vardal,   Erling.
Despite the failure of the U.N. Copenhagen climate conference in December 2009 efforts are continuing to reach agreement on binding global commitments on greenhouse gas (GHG) emissions. At the same time, efforts are still underway to conclude the Doha Round of trade negotiations through the World Trade Organization (WTO). Both of these agreements could have a significant impact on the level of activity in agriculture and the GHG emissions that it generates. In this paper we explore strategies to comply with both trade liberalization and GHG emission reduction commitments. We examine the implications of trade liberalization and a carbon tax, both of which affect agricultural output, as means of achieving emission reductions. We emphasize two diametrically...

Activity of Exoenzymes in Treated Wastewater Irrigated Soils
Provedor de dados: 17
Autores: Elisabeth J&amp;#xfc;schke; Bernd Marschner.
The reuse of reclaimed wastewater for irrigation of agricultural fields greatly influences the activity of soil microorganisms through the input of organic compounds. Due to the production of exoenzymes by microorganisms for the decomposition of substrates it can be assumed that the irrigation with treated wastewater (TWW) has a strong influence on the soil enzyme pool. In this study the activity of ten exoenzymes, which catalyses processes in C, N and P nutrient cycles, were determined in 3 different soils in 0-10, 10-20, 20-30, 30-50, 50-70 and 70-100 cm soil depth. The soils were used for agriculture and irrigated with reclaimed wastewater reused after a secondary treatment step. Additionally a control after freshwater irrigation was studied. Due to the...

Activity pattern of Cuniculus paca (Rodentia: Cuniculidae) in relation to lunar illumination and other abiotic variables in the southern Brazilian Amazon
Provedor de dados: 103
Autores: Michalski,Fernanda; Norris,Darren.
Understanding what influences the activity of organisms is important for both ecological understanding and species conservation. Using data from 2,707 camera trap days distributed across 24 forest sites, we present quantitative analyses of the activity pattern of Cuniculus paca (Linnaeus, 1766) in southern Amazonia. We compared the activity pattern of this species across four designated subsets of the 24-hours diel cycle (dawn, dusk, day and night). Using linear regression models we tested the influence of season, temperature and rainfall on the activity patterns of C. paca (paca). We also evaluated the nocturnal photos of paca (N = 111) as a function of the degree of lunar illumination in order to test the prediction that pacas minimize their activity...

Autores: Perera,Carmen Laura; Díaz de Arce,Heidy; Pérez,L.J.
El virus de la influenza aviar provoca infección, enfermedad y muerte en diferentes especies de aves, además ha adquirido la capacidad de propagarse del hospedador aviar a humanos y otros mamíferos, provocando una enfermedad grave. Por ese motivo, existe una gran preocupación a nivel internacional en la detección del virus de la influenza aviar y las estrategias de diagnóstico. A pesar que los métodos de laboratorios convencionales son ampliamente usados para el aislamiento e identificación de los virus y para la detección de anticuerpos específicos en todo el mundo, nuevas tecnologías han sido rápidamente desarrolladas. Con el empleo de las herramientas moleculares se puede realizar en un mismo día de la detección, patotipificación y caracterización...

La política en educación primaria y media, siguiendo a M. Luna y A. Astorga se ha caracterizado en las últimas tres décadas por la ampliación de la oferta privada y por los intentos focalizados de reforma a través de proyectos del Banco Mundial y del Banco Interamericano de Desarrollo los cuales declaraban como objetivos la mejora de logros académicos, la formación docente, la autonomía administrativa de las escuelas y la focalización. En este número analizamos la situación de los esfuerzos por mejorar la calidad de la educación y constatamos que los resultados son más bien contrarios a lo que se esperaba. En la sección Actores, Patricio Rivas analiza las diversas acepciones de calidad en la educación que son elaboradas por actores del sector, lo que nos...

Actuarial Impacts of Loss Cost Ratio Ratemaking in U.S. Crop Insurance Programs
Provedor de dados: 31
Autores: Woodard,   Joshua D.; Sherrick,   Bruce J.; Schnitkey,   Gary D.
This study examines the actuarial implications of the loss cost ratio (LCR) ratemaking methodology employed by the Risk Management Agency as a component of base rates for U.S. crop insurance programs, and identifies specific conditions required for the LCR methodology to result in unbiased rates when liabilities trend. Specifically, constant relative yield risk resulting in growing absolute variance through time and other restrictive requirements are required for the LCR to result in unbiased rates. These requirements are tested against a large farm-level data set for Illinois corn. Our findings indicate that the conditions required for appropriate use of the LCR methodology are violated for this high premium volume market, resulting in large implied rate...

Adaptation approaches to climate change in China: An operational framework
Provedor de dados: 31
Autores: Jiahua,   Pan; Yan,   Zheng; Markandya,   Anil.
Climate change poses great risks for China, which makes adaptation an essential response. However, adaptation planning and implementation are still at a preliminary stage with respect to the theoretical framework and methodology. This article focuses on the status, problems and basic needs as regards adaptation to climate change, and outlines the operational framework that the government is seeking to pursue for China’s adapting to climate change. The conclusion is that, to satisfy the basic needs of development, it is necessary to clarify development-oriented and incremental adaptation. Furthermore measures to enhance adaptive capacity can be classified as infrastructure-based, technology-based and institutional. Lastly the authors stress the importance...

Adaptation Can Help Mitigation: An Integrated Approach to Post-2012 Climate Policy
Provedor de dados: 31
Autores: Bosello,   Francesco; Carraro,   Carlo; De Cian,   Enrica.
The latest round of international negotiations in Copenhagen led to a set of commitments on emission reductions which are unlikely to stabilise global warming below or around 2°C. As a consequence, in the absence of additional ambitious policy measures, adaptation will be needed to address climate-related damages. What is the role of adaptation in this setting? How is it optimally allocated across regions and time? To address these questions, this paper analyses the optimal mix of adaptation and mitigation expenditures in a cost-effective setting in which countries cooperate to achieve a long-term stabilisation target (550 CO2-eq). It uses an Integrated Assessment Model (AD-WITCH) that describes the relationships between different adaptation modes...

ADAPTATION OF MEDITERRANEAN CROPS TO WATER PRESSURE IN THE EBRO BASIN: A WATER EFFICIENCY INDEX
Provedor de dados: 31
Autores: Fernandez-Haddad,   Zaira; Quiroga,   Sonia.
In this paper, we assess the output-oriented technical efficiency of agricultural production functions in order to compare, over time, economic and environmental production processes in the different regions of the Spanish Ebro basin, in a climate change context. The measurement of technical efficiency in agriculture can provide useful information about the competitiveness of farms and their potential to increase its productivity moreover can help in the crops adaptation to water pressure by improving the management of scarce resources. Here, we generate an agricultural water efficiency index to evaluate the adaptation of some Mediterranean crops to the water pressures in this area. We estimate frontier production functions and technical efficiency...

Adapting agriculture to climate change
Provedor de dados: 31
Autores: Iglesias,   Ana; Quiroga,   Sonia; Diz,   Agustin; Garrote,   Luis.
We evaluate the potential impacts and measure the potential limits of adaptation of agriculture to climate change. Pressures on land and water resources are expected to intensify existing risks in low latitude areas – e.g., South-East Asia deltas – and in regions with current water scarcity – e.g. Mediterranean, and create new opportunities in some northern temperate areas – e.g., Northern Russia, Northern Europe. The need to respond to these risks and opportunities is addressed by evaluating the costs and benefits of a number of technical and policy actions. The discussion aims to assist stakeholders facing the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

Adaptive evolution of the vertebrate skeletal muscle sodium channel
Provedor de dados: 74
Autores: Lu,Jian; Zheng,Jianzhou; Xu,Qinggang; Chen,Keping; Zhang,Chiyu.
Tetrodotoxin (TTX) is a highly potent neurotoxin that blocks the action potential by selectively binding to voltage-gated sodium channels (Na v). The skeletal muscle Na v (Na v1.4) channels in most pufferfish species and certain North American garter snakes are resistant to TTX, whereas in most mammals they are TTX-sensitive. It still remains unclear as to whether the difference in this sensitivity among the various vertebrate species can be associated with adaptive evolution. In this study, we investigated the adaptive evolution of the vertebrate Na v1.4 channels. By means of the CODEML program of the PAML 4.3 package, the lineages of both garter snakes and pufferfishes were denoted to be under positive selection. The positively selected sites identified...

Adding automated data analysis and biological evaluation to affyanalysisQC
Provedor de dados: 17
Autores: Anwesha Dutta.
Almost every cell in the body contains a full set of chromosomes and identical genes. However, only a fraction of these genes are turned on, at any given time and it is this subset of genes that are expressed, which confers unique properties to each cell type.  Gene expression is the term used to describe the transcription of the information contained within the DNA into messenger RNA (mRNA) molecules that are then translated into proteins which perform most of the critical functions of cells. &amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Gene expression is a highly complex and tightly regulated process that allows a cell to respond dynamically both to environmental stimuli and to its own changing needs. This mechanism acts as both an on/off switch to control which...

Autores: Montero-Cortés,Mayra I.; Chan-Rodríguez,José L.; Cordova-Lara,Ivan; Oropeza-Salin,Carlos; Sáenz-Carbonell,Luis.
Coconut (Cocos nucífera L.) production has been declining in México and other countries due to deadly diseases; therefore, massive production of palms resistant to diseases is needed for replanting. Production of somatic embryos and micropropagation could be a very useful technique to produce free disease coconut population. Explants (embryogenic-structures) of Pacific Tall 2 ecotype were cultured in an induction medium defined as I (semisolid Y3 medium containing 0.65 mM 2,4-dichlorophenoxyacetic acid) and treated with the cytokinin benzyladenine (BA) at 0, 25, 100 or 200 ,µM to evaluate its effect on embryogenic callus formation. The BA treatments did not affect the percentage of embryogenic callus formation. In order to evaluate the effect of the BA...

Addition of green banana flour to instant noodles: rheological and technological properties
Provedor de dados: 64
Autores: Vernaza,Maria Gabriela; Gularte,Márcia Arocha; Chang,Yoon Kil.
Nowadays, there is considerable concern about the consumption of high fat and low fiber foods. The objective was to develop instant noodles (IN) with functional properties by adding 10% green banana flour (GBF), and determine the effect of this on the dough rheological properties. Noodles were obtained through sheeting, steaming and frying process. The IN were characterized for their moisture, fat, resistant starch (RS), texture and color. The proximate composition showed that GBF was rich in ash (3.16%), fiber (8.88%) and RS (45.70%), being an attractive raw material for the production of functional IN. When 10% GBF was added, rheological properties of dough changed because of dilution of gluten, making it weaker, but with enough extensibility and...

Adeno-associated virus for cystic fibrosis gene therapy
Provedor de dados: 56
Autores: Martini,S.V.; Rocco,P.R.M.; Morales,M.M.
Gene therapy is an alternative treatment for genetic lung disease, especially monogenic disorders such as cystic fibrosis. Cystic fibrosis is a severe autosomal recessive disease affecting one in 2500 live births in the white population, caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR). The disease is classically characterized by pancreatic enzyme insufficiency, an increased concentration of chloride in sweat, and varying severity of chronic obstructive lung disease. Currently, the greatest challenge for gene therapy is finding an ideal vector to deliver the transgene (CFTR) to the affected organ (lung). Adeno-associated virus is the most promising viral vector system for the treatment of respiratory disease because it...

O adensamento de novos plantios (600 a 1.500 plantas/há-1) é uma estratégica adotada para ampliação da produtividade. A cultura dos citros apresenta boa resposta de produção quando cultivada sob maiores densidades, e este sistema é um dos responsáveis pelo aumento de produtividade observado nos últimos oito anos em São Paulo (média de 400 para 600 caixas de 40,8 Kg/ha-1), além de prognóstico de maiores ganhos no futuro próximo á medida que se reduzem os espaçamentos. Tradicionalmente, o espaçamento recomendado até início da década de 90 ficava em torno de 7 a 9 m na entrelinha e 4 a 6 metros na linha de plantio, mas laranjeiras doces apresentaram excelentes produções em espaçamentos de 5 a 7 m na entrelinha e 2 a 4 m na linha de plantio.

ADOPT: a tool for predicting adoption of agricultural innovations
Provedor de dados: 31
Autores: Kuehne,   Geoff; Llewellyn,   Rick S.; Pannell,   David J.; Wilkinson,   Roger; Dolling,   P.; Ewing,   Michael A.
A wealth of evidence exists about the adoption of new practices and technologies in agriculture but there does not appear to have been any attempt to simplify this vast body of research knowledge into a model to make quantitative predictions across a broad range of contexts. This is despite increasing demand from research, development and extension agencies for estimates of likely extent of adoption and the likely timeframes for project impacts. This paper reports on the reasoning underpinning the development of ADOPT (Adoption and Diffusion Outcome Prediction Tool). The tool has been designed to: 1) predict an innovation‘s likely peak extent of adoption and likely time for reaching that peak; 2) encourage users to consider the influence of a structured...

Adopting Nrf2 and NF-&amp;#x3ba;B from cancer: Is there any role of the duo in diabetes?
Provedor de dados: 17
Autores: Geeta Negi; Ashutosh Kumar; Shyam S. Sharma.
Oxidative stress and inflammation are two well-recognized events occurring in normal cells during cancer chemotherapy. Several antioxidant and anti-inflammatory agents have therefore been tried as rational and effective strategies for chemoprotection. Elaborate studies on antioxidants and anti-inflammatory agents in various experimental models of cancer revealed that these agents act by modulating the expression and/or activity of the transcription factors nuclear factor erythroid 2-related factor 2 (Nrf2) and nuclear factor-kappa B (NF-&amp;#x3ba;B). Nrf2 is considered the main sentinel of antioxidant defense as it induces many antioxidant and phase 2 enzymes in response to stressful conditions. Likewise, NF-&amp;#x3ba;B is considered as a denominator of...

Adoption of organic farming: Are there differences between early and late adoption?
Provedor de dados: 21
Autores: Läpple, D.; Van Rensburg, T.
Based on the fact that not all farmers adopt a technology at the same time, it is argued in this paper that the distinction between groups is important because early, medium and late adopters respond differently to economic and non-economic factors when they consider whether to take up organic farming or not. The individual effects on adoption between the groups are identified by the use of multinomial logit analysis. The results provide evidence that there are significant differences in the characteristics between the adopter groups. The findings also reveal that the factors that affect adoption play a different role for early, medium and late adopters, particularly with regard to farming intensity, age, information gathering as well as attitudes of the...

Adoption of Pollution Prevention: The Role of Information Spillover, Mandatory Regulation, and Voluntary Program Participation
Provedor de dados: 31
Autores: Bi,   Xiang; Deltas,   George; Khanna,   Madhu.
Interest in promoting Pollution Prevention (P2) has been increasing since 1991, following the passage of the Pollution Prevention Act (PPA) of 1990. As part of the PPA, facilities that are subject to the Toxics Releases Inventory (TRI) are required to disclose the number of incremental P2 activities for each listed chemicals from 1991 onward. Though the disclosure is required by the PPA, the adoption of P2 remains a voluntary initiative by firms. To promote P2 ethic among firms, the U.S.EPA has established several voluntary programs and P2 information clearinghouse. P2 technologies were more likely to be facility- and operation- specific and involved considerable information costs and uncertainty. Firms might learn about P2 technologies from their peers...

This study has evaluated the superiority of resource conservation technologies (RCTs) over conventional methods of cultivation and has identified the factors influencing adoption of these technologies. It has provided succinct evidences from four states — Bihar, Haryana, Punjab and Uttar Pradesh — by comparing the adopters and non-adopters of RCTs in the rice-wheat cropping system of the Indo-Gangetic Plains of India. The study has highlighted superiority of RCTs over the conventional practices in terms of cost saving and efficient inputs-use. However, there is a need to internalize the RCTs in their totality by applying plans and strategies based on local dynamics. The study has suggested the need of policy formulations for dissemination and wider...

Autores: Nair,   Shyam; Wang,   Chenggang; Segarra,   Eduardo; Belasco,   Eric J.; Velandia,   Margarita M.; Reeves,   Jeanne M.
A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen.  The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs.  The farmers adopting both soil and plant based VDTs are more likely to adopt VRT.  The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted.  In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they...

Autores: Núñez,Cecilia I.; Amico,Guillermo C.
El color verde de los frutos maduros podría atribuirse a la capacidad de adquirir carbono mediante fotosíntesis, lo cual disminuye los costos reproductivos e incrementa la recompensa nutritiva para los dispersores de semillas. En el muérdago Tristerix corymbosus (Loranthaceae) el color de los frutos maduros varía según el bioma: en el matorral chileno los frutos son amarillos mientras que en el bosque templando son verdes. Nuestro objetivo fue determinar si el color de los frutos se relacionaba con la capacidad de ganar carbono vía fotosíntesis y si esta capacidad variaba con la madurez y el bioma. Realizamos mediciones fisiológicas en plantas provenientes de poblaciones de cada bioma. Los frutos, tanto inmaduros como maduros de cada bioma no mostraron...

Um experimento foi conduzido para estudar a adsorção de fósforo (P) em amostras de dez solos do Estado de Pernambuco, Nordeste do Brasil. As relações entre atributos físicos e químicos do solo e as isotermas de adsorção de P foram também avaliadas. Os resultados mostraram que a capacidade máxima de adsorção de fosfato (CMAP), o P-remanescente (P-rem) e a constante k de da equação Freundlich são variáveis confiáveis para se caracterizar a adsorção de P pelos solos. Pela sua praticidade de determinação, o P-rem é a variável mais indicada. Os parâmetros de adsorção de P CMAP, P-rem e constante k de Freundlich apresentaram correlação (p &lt; 0,01) com os atributos químicos acidez potencial (H+Al), alumínio trocável (Al), capacidade de troca catiônica (CTC) e...

Adubação antecipada no sistema plantio direto.
Provedor de dados: 14
Autores: KURIHARA, C. H.; HERNANI, L. C.
No Sistema Plantio Direto (SPD), o ambiente edáfico é profundamente alterado em relação ao sistema convencional de preparo do solo, que se caracteriza pelo uso intenso de implementos para o revolvimento deste. As condições encontradas em cultivos sob SPD são resultantes dos efeitos da manutenção dos resíduos sobre a superfície, do incremento do teor da matéria orgânica, da pequena movimentação ou perturbação do solo e da maior atividade de micro-organismos sobre os demais atributos físicos, químicos e biológicos. Trabalhos de pesquisa realizados em diferentes regiões do País têm demonstrado que essas alterações resultam em maior eficiência de aproveitamento dos nutrientes e da água no solo, permitindo a aplicação de fertilizantes a lanço, em superfície.

Adubação e calagem em vinhedos.
Provedor de dados: 14
Autores: BRUNETTO, G.; SCHMITT, D. E.; MELO, G. W. B. de.
A videira, como outras frutíferas, possui características de absorção e utilização de nutrientes diferentes das encontradas nas culturas anuais como, por exemplo, o milho. Por isso, as técnicas de adubação e de calagem usadas para as culturas anuais são distintas daquelas usadas, por exemplo, para a videira. O volume de solo explorado pelas raízes das videiras e o período de absorção de nutrientes do solo são maiores, comparativamente, às culturas anuais. Na videira, a maioria das raízes podem ser localizadas até a profundidade de 40 em, mas as raízes mais finas, que são responsáveis pela absorção da maior quantidade de nutrientes, são encontradas nas camadas mais superficiais do solo e, por isso, a aplicação da maioria das fontes de fertilizantes nas...

O baixo teor de fósforo nos solos tropicais torna essencial pesquisas sobre sua adubação em culturas pouco estudadas como o inhame. Assim, o objetivo foi avaliar a produtividade do inhame (cultivar Da Costa) em função de doses de fósforo e épocas de colheita. De fevereiro a dezembro de 2009 foi conduzido um experimento em delineamento experimental de blocos casualizados, em parcelas subdivididas, em quatro repetições. Nas parcelas foram avaliadas seis doses de fósforo (0, 100, 200, 300, 400 e 500 kg ha-1 de P2O5), e nas subparcelas duas épocas de colheitas (sete e nove meses após o plantio). Os pesos máximos de túberas colhidas aos sete e aos nove meses foram 1,94 e 2,20 kg com 245 e 240 kg ha-1 de P2O5, respectivamente. Não houve efeito das doses de...

Advances in apple culture worldwide
Provedor de dados: 94
Autores: Robinson,Terence.
Over the last 60 years, planting densities for apple have increased as improved management systems have been developed. Dwarfing rootstocks have been the key to the dramatic changes in tree size, spacing and early production. The Malling series of dwarfing rootstocks (M.9 and M.26) have been the most important dwarfing rootstocks in the world but are poorly adapted in some areas of the world and they are susceptible to the bacterial disease fire blight and the soil disease complex, apple replant disease which limits their uses in some areas. Rootstock breeding programs in several parts of the world are developing improved rootstocks with resistance to fire blight, and replant disease, and improved cold hardiness and yield efficiency. A second important...

Autores: Le Menn, Marc; De La Tocnaye, J. L. De Bougrenet; Grosso, P.; Delauney, Laurent; Podeur, Christian; Brault, P.; Guillerme, O.
Absolute salinity measurement of seawater has become a key issue in thermodynamic models of the oceans. One of the most direct ways is to measure the seawater refractive index which is related to density and can therefore be related to the absolute salinity. Recent advances in high resolution position sensitive devices enable us to take advantage of small beam deviation measurements using refractometers. This paper assesses the advantages of such technology with respect to the current state-of-the-art technology. In particular, we present the resolution dependence on refractive index variations and derive the limits of such a solution for designing seawater sensors well suited for coastal and deep-sea applications. Particular attention has been paid to...

Autores: Shuobo Shi.
During the last decade of years, remarkable technological innovations have emerged that allow the direct or indirect determination of the transcriptome at unprecedented scale and speed. Studies using these methods have already altered our view of the extent and complexity of transcript profiling, which has advanced from one-gene-at-a-time to a holistic view of the genome. Here, we outline the major technical advances in transcriptome characterization, including the most popular used hybridization-based platform, the well accepted tag-based sequencing platform, and the recently developed RNA-Seq (RNA sequencing) based platform. Importantly, these next-generation technologies revolutionize assessing the entire transcriptome via the recent RNA-Seq technology.

The objectives of this research were to analyse data on the international market of frozen boneless beef and to classify its participants into groups according to their trade relationships, identifying the main factors that influence the preference of a country to beef from a determined supplier country. International beef trade is composed of two markets: in one of them, the relationships between supplier and client depend on the lowest price, and Brazil is found in favorable conditions; and the other, the relationships are preferably based on the sanitary quality of the herd and traceability systems recognized by the purchaser, to which Brazilian participation is low.

Aedes aegypti survival in the presence of Toxorhynchites violaceus (Diptera: Culicidae) fourth instar larvae
Provedor de dados: 103
Autores: Albeny,Daniel S; Martins,Gustavo F; Andrade,Mateus R; Krüger,Rodrigo F; Vilela,Evaldo F.
The mosquito Aedes aegypti (Linnaeus, 1762) is the main vector of dengue and yellow fever viruses. Different methods have been used to control A. aegypti, including chemical and biological tools. However, chemical control can lead to a subsequent increase in the mosquitoes' insecticide resistance, and biological control represents an important method as an alternative to insecticide usage. Larvae from the Toxorhynchites genus (Diptera: Culicidae) are predators of other mosquitoes and represent a potential natural biocontrol agent of A. aegypti larvae. In the present work, A. aegypti larval survival was studied in the presence of the neotropical Toxorhynchites violaceus (Wiedemann, 1821) fourth instar larvae.

Autores: Wang,Ping; Nong,Xu-Hua; Ge,Jie-Hong.
Nonylphenol ethoxylates (NPEOs), which are widely used for industrial and domestic purposes, exert adverse effects on wildlife after being used and discharged into the environment. However, their ultimate biodegradability and biodegradation pathway remains unclear. In this study, the aerobic degradability of nonylphenol ethoxylates (NPEOs) by the acclimated microorganisms in active sludge was examined using shaking-flask tests. The degradation of benzene rings in NPEOs was determined using UV spectroscopy and high performance liquid chromatography (HPLC). Results showed that more than 80% of benzene rings were removed after 8-10 days of degradation, and the majority of NPEOs were also removed after 9 days of degradation, indicating NPEOs and the benzene...

Aerobic exercise training in heart failure: impact on sympathetic hyperactivity and cardiac and skeletal muscle function
Provedor de dados: 56
Autores: Brum,P.C.; Bacurau,A.V.N.; Medeiros,A.; Ferreira,J.C.B.; Vanzelli,A.S.; Negrão,C.E.
Heart failure is a common endpoint for many forms of cardiovascular disease and a significant cause of morbidity and mortality. Chronic neurohumoral excitation (i.e., sympathetic hyperactivity) has been considered to be a hallmark of heart failure and is associated with a poor prognosis, cardiac dysfunction and remodeling, and skeletal myopathy. Aerobic exercise training is efficient in counteracting sympathetic hyperactivity and its toxic effects on cardiac and skeletal muscles. In this review, we describe the effects of aerobic exercise training on sympathetic hyperactivity, skeletal myopathy, as well as cardiac function and remodeling in human and animal heart failure. We also discuss the mechanisms underlying the effects of aerobic exercise training.

El aclareo puede modificar la distribución y cantidad de biomasa aérea en función del tiempo de respuesta y de las condiciones de crecimiento. En este estudio se analizó el efecto de aclareos en la distribución y contenido de biomasa aérea acumulada de Pinus patula mediante muestreos destructivos de 30 árboles en 2009, después de estar sometidos a diferentes intensidades de aclareo desde el 2004, más un testigo intacto. La eliminación entre 40 y 69 % de la densidad inicial de plantación afectó significativamente (p ≤ 0.05) la cantidad y distribución de biomasa foliar y la cantidad de madera con corteza en el fuste a nivel de árbol individual (pero no por ha) en algunos componentes del árbol. Las intensidades altas de aclareo (65.3 y 68.7 %&gt;) y las...

Affordances of distractors and compatibility effects: a study with the computational model TRoPICALS
Provedor de dados: 17
Autores: Daniele Caligiore; Anna M. Borghi; Domenico Parisi; Rob Ellis; Angelo Cangelosi; Gianluca Baldassarre.
Seeing an object activates in the brain both visual and action codes. Crucial evidence supporting this view is offered by compatibility effect experiments (Ellis et al. (2007). J Exp Psychol: Hum Percept Perform): perception of an object can facilitate or interfere with the execution of an action (e.g. grasping) even when the viewer has no intention of interacting with the object. TRoPICALS (Caligiore et al. (2010). Psychol Rev) is a computational model developed to study compatibility effects. It provides a general hypothesis about the brain mechanisms underlying compatibility effects, suggesting that the top-down bias from prefrontal cortex (PFC), and its agreement or disagreement with the affordances of objects, plays a key role in such phenomena....

Afforestation and Timber Management Compliance Strategies in Climate Policy. A Computable General Equilibrium Analysis
Provedor de dados: 31
Autores: Michetti,   Melania; Nunes Rosa,   Renato.
This paper analyzes the role of afforestation-reforestation and timber management activities, and their major and secondary economic effects in stabilizing climate during the first commitment period of the Kyoto Protocol. In particular, with a Computable General Equilibrium framework, the ICES model, it is inferred how forest carbon sequestration fits within the European domestic portfolio of a 2020-20 and 2020-30 climate stabilization policy. Afforestation and land use are accounted for by introducing their effects in the model. This is done by relying on carbon sequestration curves provided by Sohngen (2005), which describe the average annual cost of sequestration for selected world regions. Results show that afforestation and timber management could...

Provedor de dados: 63
Autores: Devran,Zübeyir; Firat,Ahmet Fikret; Tör,Mahmut; Mutlu,Nedim; Elekçioğlu,Ibrahim Halil.
Root-knot nematodes (Meloidogyne spp.) are an important worldwide pest of cucumber (Cucumis sativus L.). Molecular markers linked to the Javanese root-knot nematode (M. javanica) resistance gene mj in cucumber may aid marker assisted selection. One-hundred AFLP (EcoRI-MseI) and 112 SRAP were used to screen resistant and susceptible parents for polymorphisms to develop molecular markers linked to the mj gene. Of the 100 AFLP primers, 92 produced bands and two yielded candidate markers (E-ATT/M-CAA and E-AAC/M-CTG). These two bands were cut off from polyacrylamide gel, cloned and sequenced. Primers designed from the sequences did not yield polymorphic bands between the parents. In addition, the sequences did not contain any restriction site or indel to be...

African Regional Integration: Implications for Food Security
Provedor de dados: 31
Autores: van Dijk,   Michiel.
This report looks at the African regional trade, regional integration agreements (RIAs) and the implications for food security. An overview is presented on the present state of African regional integration and the determinants of regional trade in agriculture and food commodities. In particular the study focuses on eight target countries, related RIAs and a set of strategic food commodities. The evidence presented in this study shows that African countries have made progress in opening up agriculture and food trade with partner countries. With, the exception of Ghana, Tanzania and Mozambique, the effective applied tariff rates for regional trade partners are substantially lower than the (MFN) rates applied to world trade partners. Nonetheless, regional...

De agrarische sector in Nigeria bloeide, totdat de olieindustrie opkwam. Van die industrie heeft slechts een klein deel van de bevolking geprofiteerd. Men komt nu tot het inzicht dat landbouw weer één van de pijlers van de economie zou moeten worden, en dat biologische land- bouw daarin een belangrijk aandeel moet hebben. Nigeria heeft nog veel te winnen.

Against the grain
Provedor de dados: 21
Autores: Döring, Thomas F.; Crowley, Oliver; Wolfe, Martin.
An Organic Research Centre project is examining how diversity-based tools can assist in the on-farm improvement of organic wheat.  Successful organic crop production requires varieties that are resistant to diseases, competitive against weeds, and effective at scavenging nutrients. Yet conventional plant breeding has largely neglected organic systems by breeding varieties exclusively for high input conditions. As a consequence, organic producers currently do not have enough choice of plant varieties for organic conditions.  One way to expand the choice is to create plant diversity anew and subject it to natural selection on organic farms.  After several generations the dominating plants would be better suited to organic systems. This idea is being tested...

Provedor de dados: 103
Autores: Souza-Conceição,José Maria; Schwingel,Paulo Ricardo.
Age and growth of Cetengraulis edentulus (Cuvier, 1828) in the Saco dos Limões bight (Southern Brazil) were studied. Sampling was carried out from August 2001 to July 2003. The study of age and growth was based on the interpretation of the periodicity of ring formation in the otoliths sagittae of 491 individuals, temporal variation of otolith edge, relative marginal increments (RMI), age-length key, and von Bertalanffy curve. Cetengraulis edentulus otoliths were adequate for the interpretation of age with 86% of legibility, in which a translucent zone and its adjacent opaque zone were deposited each year. The translucent zone is formed during the cold period and the opaque zone in the warm period. Fish aged 0 (&lt;12 months) - 4.0 year old were found and...

Autores: Previero,Marília; Minte-Vera,Carolina V.; Freitas,Matheus Oliveira; Moura,Rodrigo Leão de; Dei Tos,Claudenice.
We determined the age and growth of the dog snapper (Lutjanus jocu), caught in the region of Abrolhos Bank, Bahia State, by the fishermen from coastal communities of Prado, Alcobaça, Caravelas, and Nova Viçosa. We examined 205 sectioned otoliths of fish caught by harpoon, longline, hand line, and gill nets (14.5 to 79.5 cm fork length). The formation of each ring was considered annual. The sectioned otoliths showed between 0 and 29 rings. Nearly half of the analyzed specimens had between 0 and 7 rings (88 of 205). Fish caught with nets in the estuarine region were the juvenile, while fish caught with lines and harpoons were the oldest. Two von Bertalanffy growth models were fitted to length-at-age data: one assuming constant variance of length-at-age (SVB)...

Autores: Francisco,Talitha M.; Ambrósio,Angela Maria; Balbi,Thiago José; Zuliani,Marina S.; Okada,Edson K.; Gomes,Luiz C.
Age and growth parameters of cachara Pseudoplatystoma reticulatum (Eigenmann &amp;amp; Eigenmann, 1889) (Siluriformes, Pimelodidae) (males and females) were estimated through the analysis of growth rings in spines of pectoral fins. Fish were collected from January to December 2007, in the area directly influenced by the Aproveitamento Múltiplo de Manso (APM Manso) and in the Cuiabá River (upper parts of the Pantanal). The maximum number of growth rings was seven for males, and eight, for females. The analysis of temporal variations in mean marginal increment showed that rings found in the spines were formed annually, in December. Growth rings were associated to spawning (in the study region from November to March) of the species. The growth curve in length...

Autores: Healey, B.p; Mahe, Kelig; Cossitt, G.; Dufour, Jean-louis; Felix, Jerome; Hicks, H.f.; Hiscock, C.; Schwab, P.
Atlantic cod (Gadus morhua) in NAFO subDivision 3Ps are exploited and jointly managed by Canada and France. Assessments of stock status incorporate age determinations from both countries when dis-aggregating total catches into catch-at-age. An otolith exchange was initiated to evaluate the degree of consistency in the age determinations of Canadian and French personnel. Both graphical and statistical analysis clearly indicate differences in interpretation between Canadian and French readers, with ages assigned by Canadian personnel generally being one-year greater than those of participants from France. However, consistency in age determinations was relatively high within Canada and within France.

AGE DIFFERENCES AND MACROECONOMIC EFFECTS ON FOOD STAMP PROGRAM PARTICIPATION
Provedor de dados: 31
Autores: Lim,   So Yeong; Chen,   Susan E.; Waldorf,   Brigitte S.
Low income populations are more severely affected by economic downturns than their high income counterparts because they are at high risk of unemployment and face reduced earnings in recessions. The use of food stamp benefits and other types of welfare are one mechanism that families can use to buffer the economic shock brought about by income losses due to unemployment during a recession. As a result, during unfavorable economic conditions, low income households disproportionately rely on public assistance including food stamps.  What is less understood are the differential effects of macroeconomic conditions on the participation propensities of different population subgroups. Of particular importance are differential effects by age. Depending on their...

Autores: Lim,   So Yeong; Chen,   Susan E.; Waldorf,   Brigitte S.
This study examines Food Stamp Program (FSP) participation patterns with an emphasis on macroeconomic effects and age differences. Entry into and exit out of the program are examined with data from the Survey of Income and Program Participation 2004 panel using probit techniques. The results indicate that young adults easily enter the FSP but quickly move out. Older people are hesitant to enter the FSP but they stay on longer compared to their younger counterparts. The estimation results confirm the common belief that economic dynamics and FSP participation are negatively related. When the unemployment rates rise, the likelihood of entry and continuation on food stamps increases. This study also documents that the macroeconomic effects on FSP transitions...

Agent Behavior under Risky and Uncertain Conditions. An Empirical Verification of Irving Fisher’s Notion of Time Preference
Provedor de dados: 31
Autores: Balgah,   Roland Azibo; Buchenrieder,   Gertrud.
Irving Fisher's theory on time preference in the 1930s arguably influenced the analysis of agents' current behavior with respect to future outcomes. By suggesting linear discount rates implying rational and self-interested motives of agents, Fisher substantiated neoclassical economic thinking. However, Fisher's notion of time preference, the choice between present and future enjoyment that actually integrates a psychological discounting component has not received similar attention in the scholarly literature. This paper aims at closing this gap. It empirically examines agent behavior under uncertain conditions culminating from natural shocks, and differentiates the psychic from the physical component. To empirically test Fisher's notion of time preference,...

The objective of this work was to evaluate the aggregate stability of tropical soils under eucalyptus plantation and native vegetation, and assess the relationships between aggregate stability and some soil chemical and physical properties. Argisols, Cambisol, Latosols and Plinthosol within three eucalyptus-cultivated regions, in the states of Espírito Santo, Rio Grande do Sul and Minas Gerais, Brazil, were studied. For each region, soils under native vegetation were compared to those under minimum tillage with eucalyptus cultivation. The aggregate stability was measured using the high-energy moisture characteristic (HEMC) technique, i.e., the moisture release curve at very low suctions. This method compares the resistance of aggregates to slaking on a...

Aggregation Issues in the Estimation of Linear Programming Productivity Measures
Provedor de dados: 31
Autores: Shaik,   Saleem; Mishra,   Ashok K.; Atwood,   Joseph A.
This paper demonstrates the sensitivity of the linear programming approach in the estimation of productivity measures in the primal framework using Malmquist productivity index and Malmquist total factor productivity index models. Specifically, the sensitivity of productivity measure to the number of constraints (level of dis-aggregation) and imposition of returns to scale constraints of linear programing is evaluated.  Further, the shadow or dual values are recovered from the linear program and compared to the market prices used in the ideal Fisher index approach to illustrate sensitivity.  Empirical application to U.S. state-level time series data from 1960-2004 reveal productivity change decreases with increases in the number of constraints.  Further,...

Aggression and dominance in cichlids in resident-intruder tests: the role of environmental enrichment
Provedor de dados: 83
Autores: Nijman,Vincent; Heuts,Boudewijn A.
When establishing dominance residents have a greater likelihood to dominate intruders than vice versa, partially because the resident has more to loose that the intruder has to win. This is known as the prior residency effect. In environmentally rich environments this effect should be stronger than in poor environments. Recently Kadry &amp;amp; Barreto (2010, Neotrop Ichthyol 8: 329-332) tested this in the pearl cichlid Geophagus brasiliensis (17 test pairs) and reported that environmental enrichment led to a reduction of aggression. We here present data on four other cichlids (332 test pairs) showing a stronger prior residency effect in enriched conditions, and, for two species, an increase in aggression. We discuss possible reasons for the differences...

Aggressive Pregnancy Tumor (Pyogenic Granuloma) with Extensive Alveolar Bone Loss Mimicking a Malignant Tumor: Case Report and Review of Literature
Provedor de dados: 77
Autores: Martins-Filho,Paulo Ricardo Saquete; Piva,Marta Rabello; da Silva,Luiz Carlos Ferreira; Reinheimer,Daniele Machado; Santos,Thiago de Santana.
Oral pyogenic granuloma is a hyperplastic inflammatory lesion commonly associated to local irritation or trauma. Females are more affected than men probably due to the vascular effects of hormones that occur during puberty, pregnancy and menopause. In the pregnancy, the lesions are known as "pregnancy tumor" and tend to occur more frequently during the second and third trimester. In the oral cavity, histopathological examination is required for diagnosis, since the lesion is clinically indistinguishable from other reactive lesions and, usually, there is no evidence of bone involvement. The authors report a rare case of pyogenic granuloma with destruction of alveolar bone mimicking a malignant tumor in a 20-year-old woman in the 19th week of pregnancy.

Autores: Cecílio,C.A.; Costa,E.H.; Simioni,P.U.; Gabriel,D.L.; Tamashiro,W.M.S.C.
The limited amount of information on the primary age-related deficiencies in the innate immune system led us to study the production of inducible nitric oxide synthase (iNOS), arginase, and cytokines in macrophages of young (8 weeks old) and old (72 weeks old) female BALB/c mice. We first evaluated iNOS and arginase inducers on peritoneal (PMΦ) and bone marrow-derived (BMMΦ) macrophages of young BALB/c and C57BL/6 mice, and then investigated their effects on macrophages of old mice. Upon stimulation with lipopolysaccharide (LPS), resident and thioglycolate-elicited PMΦ from young mice presented higher iNOS activity than those from old mice (54.4%). However, LPS-stimulated BMMΦ from old mice showed the highest NO levels (50.1%). Identical NO levels were...

Aglaenita (Hemiptera: Cicadellidae: Neocoelidiinae): a new species from Brazil
Provedor de dados: 103
Autores: Marques-Costa,Ana Paula.
Aglaenita Spinola, 1850 comprises fourteen species, all occurring in Brazil, including a new species, A. hambletoni sp. nov., which is described herein. The genus is close to Biza Walker, 1858 and Megacoelidia Kramer &amp;amp; Linnavuori, 1959. Aglaenita hambletoni sp. nov. can be distinguished from other Aglaenita species mainly by the characters of male genitalia, especially by the pygofer bearing an apical bifurcated process, the branches of the process pointed and sclerotized, the upper branch longer than the lower, tooth-like one; and by the aedeagus without processes and with the ventral margin without teeth. The diagnosis of the genus and the known geographical distribution of its species are also given

O projeto "Agricultura Apoiada pela Comunidade" (AAC) é uma alternativa de mercado utilizada na Europa e nos EUA. Neste mercado alternativo, os produtores oferecem a sua produção aos consumidores, sob a forma de cestas de alimentos, alguns meses antes de iniciarem a produção de suas culturas. Algum tempo depois, durante alguns meses, os consumidores irão receber os produtos. Atualmente, diversos países têm uma parcela significativa da sua população vivendo na pobreza. Por isso, diversas políticas públicas foram desenhadas nesses países com o objetivo de reduzi-la. O estímulo à agricultura urbana é uma dessas políticas. No entanto, frequentemente, os produtores urbanos pobres têm dificuldades para adquirir os insumos necessários para manter a sua produção....

O início da agricultura de precisão (AP) teve foco em máquinas dotadas de receptores GPS (Global Positioning System) e mapas de produtividade. Talvez, devido à essa fase, estabeleceu-se no Brasil, um senso comum de que o tema AP é uma área do conhecimento relacionada à sofisticação das máquinas agrícolas por meio de eletrônicas embarcadas e sistemas computacionais complexos, apesar do impacto final objetivar a sustentabilidade do agronegócio. A comunidade acadêmica, por sua vez, priorizou trabalhos iniciais voltados ao desenvolvimento de máquinas e equipamentos, por entender que ali estavam os principais desafios.

Agricultura e sustentabilidade
Provedor de dados: 25
Autores: Ricci, Écio A.; Rezende Filho, Cyro de B.; Fortes Neto, Paulo; Batista, Getulio T.
A agricultura como atividade econômica tem início na Pré-história. Essencial para a sedentarização da humanidade se desenvolveu para suprir as necessidades de alimentos e fibras que eram coletados na natureza. No período da Expansão Colonial européia, a atividade tornou-se empresarial na forma de plantation. A partir daí, aliado às formas primitivas de práticas agrícolas a atividade passa a ter caráter predatório. Considerando esse fato, vários autores destacados neste artigo, discutem a agricultura praticada de forma sustentável. Por outro lado, a Agricultura Familiar tem sido estudada por Veiga (1996), Gomes (2004), Pereira (2009), Caetano (2010) e Vargas (2010). Similarmente, a Agricultura Comercial foi analisada por Assad e Almeida (2004), Santos...

Agricultura em zonas ripárias do sul do Brasil: conflitos de uso da terra e impactos nos recursos hídricos.
Provedor de dados: 21
Autores: Martini, Luiz Carlos Pittol; Trentini, Élen Cristin.
O trabalho apresenta e discute a questão da proteção de zonas ripárias em áreas agrícolas do Sul do Brasil, em especial no Estado de Santa Catarina, em que predomina agricultura familiar praticada em pequenas propriedades. As exigências legais determinadas pelo Código Florestal brasileiro de 1965 são apresentadas frente às limitações para atendimento da lei impostas por fatores culturais, do meio físico e do tamanho das propriedades agrícolas. Para ilustração do problema, são confrontadas as duas correntes preponderantes no debate a respeito da utilização de áreas ripárias em Santa Catarina: aplicação dos dispositivos legais existentes versus flexibilização da lei para atender usos atuais em áreas de preservação permanente.

Agricultural Commercialization in the Uplands of Northern Vietnam: How to Achieve Both Poverty Reduction and Environmental Sustainability Goals?
Provedor de dados: 31
Autores: Keil,   Alwin; Saint-Macary,   Camille; Zeller,   Manfred.
Income growth and urbanization in developing countries have enlarged markets for highvalue agricultural commodities. However, there are concerns that lacking access to physical, financial, and human capital, as well as infrastructure and institutions limit the ability of the poor to participate in and benefit from such commercial agricultural activities. There may further be a trade-off between wealth enhancing effects of intensive commercial agriculture and adverse long-term effects on farmers’ livelihoods due to natural resource degradation. This study provides empirical evidence on these crucial issues and derives related policy recommendations using the example of Vietnam. Here, economic growth has boosted the demand for animal products and,...

Agricultural Contracting Update:  Contracts in 2008

Marketing and production contracts covered 39 percent of the value of U.S. agricultural production in 2008, up from 36 percent in 2001, and a substantial increase over 28 percent in 1991 and 11 percent in 1969. However, aggregate contract use has stabilized in recent years and no longer suggests a strong trend. Contracts between farmers and their buyers are reached prior to harvest (or before the completion stage for livestock)and govern the terms under which products are transferred from the farm. Contracts are far more likely to be used on large farms than on small farms, and they form one element in a package of risk management tools available to farmers. Production contracts are used widely in livestock production, while marketing contracts are...

Agricultural Costs of Carbon Dioxide Abatement via Land-use Adaptation on organic soils
Provedor de dados: 31
Autores: Schaller,   Lena; Kantelhardt,   Jochen; Droesler,   Matthias; Hoper,   Heinrich.
Increasing carbon dioxide emissions and related climate effects require mitigation strategies, thereby also emissions caused by agriculture are brought into the focus of political debate. In particular organic soil cultivation, inducing significant CO2 emissions is being discussed more and more. This study aims to answer the question of whether changes of organic soil management can serve as cost-efficient mitigation strategies for climate change. To this end we have built an economic model in which farm-individual and plot-specific CO2-abatement costs of selected landuse strategies are calculated by contrasting effects on the agricultural income with the related reduction in greenhouse-gas emissions. With respect to microeconomic data we use a dataset...

Agricultural Efficiency Gains and Trade Liberalization in Sudan
Provedor de dados: 31
Autores: Siddig,   Khalid H.A.; Babiker,   Babiker Idris.
The traditional agriculture in Sudan occupies 60% of the total cultivated land and employs 65% of the agricultural population. Nevertheless, it is characterized by its low crop productivity, which is mainly driven by low technical efficiency, while drought and civil conflicts threaten most of its areas countrywide.  Therefore, it has contributed only an average of 16% to the total agricultural GDP during the last decade. This paper addresses from an empirical point of view the sectoral and macroeconomic implications of agricultural efficiency improvement in Sudan and assesses the efficiency gains under the assumption of trade liberalization.

Agricultural efficiency, malaria incidence and health expenses among Ugandan farmers
Provedor de dados: 31
Autores: Ulimwengu,   John M.; Badiane,   Ousmane.
The importance of health in promoting economic development has been forcefully stated by the World Health Organization’s Commission on Macroeconomics and Health. In this paper, we look at the impact of own household health expenses on malaria incidence and ultimately on agricultural efficiency. We use a non-parametric method to estimate agricultural efficiency, therefore avoiding the issue of identification of the proper household agricultural production function. In addition the simar-wilson approach followed in this paper accounts for bias induced by serial correlation among farmers. A Tobit model with endogenous health production function is used to estimate the impact of malaria incidence on agricultural efficiency. Data come from the 2006 National...

Agricultural Market Performance in the EU after the 2000 and 2003 CAP Reform An Ex-post Evaluation based on AGMEMOD
Provedor de dados: 31
Autores: Banse,   Martin; van Leeuwen,   Myrna; Tabeau,   Andrzej A.; Salamon,   Petra; Ledebur,   Oliver von.
The paper investigates the CAP impacts on the EU agriculture by means of policy simulations conducted with the AGMEMOD model. To isolate the policy effects in the historical period 2000-2005, counterfactual simulations for this period are run. To simulate the response of the EU agriculture on different policy changes in the period 2006-2020, a ‘no-policy change’ baseline scenario is developed and then policy experiments are conducted such as the abolition of milk quota, the implementation of the regional payments and some budget cuts. To identify the policy effects, the policy scenarios are compared with the ‘no-policy change’ baseline.

Agricultural policy analysis in Finland with the AGMEMOD model: Lessons to be learnt?
Provedor de dados: 31
Autores: Niemi,   Jyrki S.; Kettunen,   Lauri.
The objective of this paper is to assess empirically the impacts of further reform of the Common Agricultural Policy (CAP) on the agri-food sector in Finland. To meet the objective, an econometric model for Finnish agriculture - built as a part of the AGMEMOD project - was utilised. The projection and policy simulations presented in the paper demonstrate that the model provides the basis for relatively straightforward baseline projection, and an initial framework for agricultural policy analysis. Yet, there remains substantial scope for further work on the model. In particular, the effects of big policy shocks are clearly not adequately captured by the model. The linear equations of supply together with low elasticities estimated from historical data...

Agricultural Price Transmission Across Space and Commodities During Price Bubbles
Provedor de dados: 31
Autores: Esposti,   Roberto; Listorti,   Giulia.
This paper analyses the horizontal transmission of cereal price shocks both across different market places and across different commodities. The analysis is carried out using Italian and international weekly spot (cash) price data and concentrating the attention on years 2006-2010, a period of generalized exceptional exuberance and consequent rapid drop of agricultural prices. The work aims at investigating how price transmission may be affected during price bubbles. The properties of price time series are firstly explored to assess which data generation process may have eventually produced the observed patterns. Secondly, the interdependence across prices is specified and estimated adopting appropriate cointegration techniques.

Agricultural Productivity and Policies in Sub-Saharan Africa
Provedor de dados: 31
Autores: Yu,   Bingxin; Nin Pratt,   Alejandro.
We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture between 1984 and 2006 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs. Policy interventions, including fiscal, trade and sector specific policies, appear to have played an important role in improving agriculture’s performance. Despite the improved agricultural performance, SSA...

Agricultural Productivity Growth in Africa: Is Efficiency Catching-up or Lagging Behind?
Provedor de dados: 31
Autores: Mugera,   Amin W.; Ojede,   Andrew.
Recent empirical studies on agricultural productivity growth in African countries have produced mixed results; some find that uptake of new technology (technical progress) is the main source of total factor productivity growth while others point to improved use of existing technology (efficiency catch-up). This study tests for efficiency catch-up in the agricultural productivity of 33 African countries from 1966 to 2001. We use recent advances in data envelopment analysis (DEA) to generate standard and bootstrap bias corrected technical efficiency scores. In general, we find no evidence of efficiency catching-up. The standard DEA overestimated the efficiency scores of some countries due to small sample bias.

Contexte  La rentabilité d'une exploitation est une condition essentielle pour assurer la réussite de la culture sans labourage dans la pratique.    Question expérimentale  Dans quelle mesure le travail réduit du sol se distingue t-il du labourage sur le plan des finances et de la gestion du travail?    Conclusion  �Dans l'essai de longue durée à Frick, le travail réduit du sol affiche de meilleurs résultats que le labourage.  Les coûts de production étant presque identiques, le rendement est le critère de jugement décisif.  Après trois ans, les premiers résultats des exploitations  pratiques ne confirment toutefois pas encore les avantages  économiques du travail du sol sans labourage.

Autores: Pfiffner, Lukas; Balmer, Oliver.
Par rapport à l'agriculture conventionnelle, l'agriculture biologique fournit sensiblement plus de prestations en faveur de la biodiversité. Selon l'altitude à laquelle elles se trouvent, les exploitations biologiques comptent entre 46 et 72 pour cent de surfaces proches de l'état naturel en plus, abritent 30 pour cent d'espèces en plus et 50 pour cent d'individus en plus que les exploitations non-biologiques. Grâce à la faible intensité d'exploitation et la proportion plus élevée de surfaces proches de l'état naturel, on rencontre encore beaucoup d'espèces végétales et animales régionales typiques sur les exploitations biologiques. Les agriculteurs peuvent ainsi profiter d'un écosystème intact et fonctionnant de manière durable.

The driving forces that determine the prospects of the agricultural sector are dominated by international and European developments related to the demand for and supply of products. In this context, European policy, (such as the CAP), and national policy (e.g. nature management) can greatly influence the development of the agricultural sector. A further reduction of the support by the government forms an important element in the expected future developments.

Agriculture’s inter-industry linkages, aggregation bias and rural policy reforms
Provedor de dados: 31
Autores: Lindberg,   Gunnar; Midmore,   Peter; Surry,   Yves R.
As agricultural policy reform and its effects have become increasingly territorialised, analyses which attempt to explain or predict impacts need to be more localised but also identify spillover effects. In addition to the predictions of policy shocks predicted by sectoral partial equilibrium models, local and regional general equilibrium approaches which establish the wider effects of such policy shocks have become popular. However, these neglect a major, underexplored difficulty: agriculture is usually described as a single sector in input-output accounts, whereas policy shocks with differential impacts have effects on other industries which are different to those implied by average input-output coefficients. Regionalisation of aggregated input-output...

Agri-environmental attitudes of Chinese farmers – The impact of social and cognitive determinants
Provedor de dados: 31
Autores: Weber,   Daniela.
Chinas’ successfully increased food production during the last 30 years has caused significant negative external impacts and subsequent escalating environmental costs (Ash and Edmonds, 1998). This dilemma has recently become a popular issue and the government attaches great importance towards a more sustainable agricultural production (UNDP, 2006). The challenge is to enhance well-grounded approaches that accomplish of effective agricultural trainings, encouraging farmers to adopt optimized practices. According to recent decision-making theories, a successful implementation is also closely related to the target group’s social and cognitive preferences. In order to get more information about farmers’ inherent decision-making factors an explorative...

Agri-Environmental Policies When the Spatial Pattern of Biodiversity Reserves Matters
Provedor de dados: 31
Autores: Bamiére,   Laure; David,   Maia; Vermont,   Bruno.
The aim of this paper is to compare different policy instruments for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as profit maximizers under technical and administrative constraints. Facing different policy measures, each farmer chooses its land-use at the field level, which determines the landscape at the regional level. A spatial pattern index (Ripley L function) is then associated to the obtained landscape, indicating on the degree of dispersion of the reserve. We compare a subsidy per hectare of reserve with an auction scheme and an agglomeration malus. We find that the auction is...

Agroforestry Survey: A Summary of Response
Provedor de dados: 21

This paper discusses the results of a survey conducted by the Organic Research Centre’s Agroecology Programme to gain an understanding of how landowners in the UK are currently using the woody components on their land, in order to assess whether there is potential from landowners to gain more both economically and ecologically from the woody components.   This survey was intended to reach a wide audience of landowners that practiced both organic and non-organic farming. Organisations that helped to distribute this survey are listed in Appendix 1.

Agroindústria familiar rural, qualidade da produção artesanal e o enfoque da teoria das convenções
Provedor de dados: 65
Autores: Nichele,Fernanda Severo; Waquil,Paulo Dabdab.
A agroindústria familiar rural surge como uma alternativa na busca de novos nichos de mercados, utilizando-se da maior diversidade de produtos e da diferenciação dos produtos através da transformação dentro da propriedade. Sua implantação é considerada uma alternativa eficaz como política de Desenvolvimento Rural, mas, com todos os esforços, existem muitas limitações neste setor, principalmente da legislação sanitária. A construção dos mercados e das regras que os regem, mesmo com o cumprimento das normas legais, vem de dentro do processo e com a colaboração de todos os atores: produtores, consumidores. A Teoria das Convenções baseia-se no reconhecimento mútuo e coletivo da qualidade ampla do produto e foi utilizada para explicar como funcionam as...

Autores: Cecílio Filho,Arthur B.; Rezende,Bráulio L.A.; Barbosa,José C.; Grangeiro,Leilson C.
Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercropped tomato and lettuce were evaluated during two seasons and compared to their sole cropping. The experimental design was a randomized complete block with nine treatments. The productivity and the classification of the tomato fruits were not influenced by having lettuce intercropped with it, but lettuce production was lowered when tomato was intercropped with it....

Autores: Camerini, M.; Taddei, F.; Bentivenga, G.; Melloni, S.; Aureli, G.; Quaranta, F.
In 2009/2010, eight durum wheat cultivars were compared in organic and conventional cropping system in two different locations of south - central Italy. A huge dataset was evaluated, including quality and agronomic traits.   As expected, grain protein content revealed to be the real Achille’s heel for organic productions, seen as average values were not far from the Italian national standard for durum wheat minimum value of protein content (11.5 %). Anyway, values lower than expected were obtained also in conventional management. Protein quality of organically produced grain was as good as the conventional one. No Deoxynivalenol (DON) contamination was recorded in organic durum wheat even in environments where significant DON levels (although clearly lower...

Aim of the breeding research in LIB-SP3 and the methods to  be used
Provedor de dados: 21
Autores: Merks, Jan.
‘Low input’ pig production systems are usually characterised by smaller herd size, more space per animal, lower capital investment, often outdoor management, provision of bedding, greater labour requirement and focus on animal welfare. Examples of ‘low input’ pig production systems are “Iberico” in Spain, “Neuland” pigs in Germany, “Scharrelvarkens” in The Netherlands, “Natura Farm” in Switzerland, “Label Rouge” in France and “Freedom Food” in United Kingdom.  Organic pig production systems have similar characteristics to those described for ‘low input systems’ above. However, organic farming standards prescribe e.g. low stocking densities, access to outdoor runs, restrict the level of ‘bought in, non-organic’ feeds etc, which usually results in higher...

Autores: Wesley Clint Hoffmann; USDA-ARS; Bradley K Fritz; USDA-ARS; Daniel E Martin; USDA-ARS.
spray drift associated with agrochemical operations is highly dependent upon the physical properties of the spray solution with respect to how they influence atomization.  This study examined two spray solutions across a wide range of solution temperatures for two nozzles spraying into two high speed airstreams.  The dynamic surface tension and viscosity of the spray solutions were also measured across the range of temperatures.  Generally as the solution temperature increased, the dynamic surface tension and viscosity both decreased.  This decrease in physical properties was directly related to the decrease in spray droplet size for all nozzles and airspeeds tested.  Monitoring of spray solution temperature throughout the spray system of a typical...

Provedor de dados: 18
Autores: Dungan, R.S.
Airborne endotoxin in occupational environments are a potential respiratory hazard to individuals.  In this study, total and inhalable airborne endotoxin samples were collected via filtration from inside animal housing units and downwind from agricultural production sites and a wastewater treatment plant.  Filter extracts were then diluted to examine the effect of interfering substances on the kinetic Limulus amebocyte lysate (LAL) assay.  In most cases, the overall endotoxin concentration was shown to decrease with increasing dilution up to 1,000-fold, suggesting the presence of enhancing substances in the filter extracts.  This dilution dependent effect was most prominent in the inhalable endotoxin samples, while total endotoxin samples displayed little...

Ajuste de parâmetros de transporte de solutos no solo utilizando Matlab 6.5
Provedor de dados: 70
Autores: Souza,Anderson L. de; Matsura,Edson E; Miranda,Jarbas H. de; Colombo,Alberto.
O sucesso na utilização de modelos matemáticos no estudo do transporte de íons no solo está intimamente ligado à precisão com que os parâmetros de transporte envolvidos neste processo são estabelecidos. De maneira geral, tais parâmetros são determinados mediante a resolução de um problema de otimização não linear em que os dados experimentais, obtidos em ensaios de deslocamento miscível, são ajustados a um modelo teórico. Neste sentido, a utilização de softwares de alta performance no ajuste destes parâmetros mostra-se vantajosa, uma vez que, além da consistência e da disponibilidade de ferramentas numéricas preexistentes, possibilita a incorporação de novas rotinas de acordo com o fenômeno que se queira simular. Sendo assim, este trabalho teve como...

Provedor de dados: 21
Autores: Sommer, Hendrik; Werner, Christina; Heine, Ulrike; Meemken, Diana; Blaha, Thomas; Sundrum, Albert.
Die Tiergesundheitssituation in der ökologischen Schweinehaltung ist seit Jahren als problematisch zu betrachten. Bei 42 Mastbetrieben, Ferkelerzeugern und geschlossenen Systemen wurde die Lage erneut untersucht. Ausgewählte Managementkriterien wurden erfasst und mit Ergebnissen vorhergehender Studien verglichen. Ferkelverluste in einer Größenordnung von 18 % (Spanne von 5-26,6%) wurden beobachtet. Obwohl etwa 80% der Betriebe ihre Ställe reinigen wird eine Desinfektion auf nur 50% der Betriebe durchgeführt. . Es besteht nach wie vor erheblicher Bedarf an der Umsetzung zielführender Managementmaßnahmen zur Verbesserung der Tiergesundheit und Reduzierung von Tierverlusten. Betriebe, die nicht in der Lage sind, ein tolerables Gesundheitsniveau zu...

Alabama Restaurant Preferences and Willingness to Pay for Local Food: A Choice Based Approach
Provedor de dados: 31
Autores: Reynolds-Allie,   Kenesha; Fields,   Deacue.
Direct marketing to restaurants has become increasingly popular as chefs desire high quality, fresh foods to meet the demand of their customers who are becoming more health conscious. Restaurants accounted for approximately 70 percent of the 2009 total food expenditures, and as a result represent a tremendous potential for developing a sustainable network with local growers.  This study seeks to determine restaurant/chefs’ preferences for local food in Alabama using choice based conjoint analysis, as well as, determine challenges faced by restaurants interested in purchasing locally.  Availability and lack of knowledge are found to be the major barriers to purchasing locally.  Results also suggest there is great potential for direct marketing to...

Alcoholic Beverages and Cigarettes: Complements or Substitutes? A Pseudo Panel Approach
Provedor de dados: 31
Autores: Koksal,   Aycan; Wohlgenant,   Michael K.
In this paper, using pseudo panel data we analyze the relation between cigarette and alcoholic beverage consumption within the rational addiction framework. We believe that pseudo panel data approach has many advantages compared to aggregate and panel data models. We found that alcoholic beverages are complements for cigarettes, while it is not the same the other way around. Moreover, we found that alcohol is a gateway for cigarette which further supports our conclusion concerning the reinforcing effect of alcohol consumption on cigarette consumption. We believe that drinking works as a trigger for smoking especially in social settings like bars while it is also possible (although less likely) that people who want to cut cigarette consumption might...

Alert at Maradi: Preventing Food Crises in West Africa by Using Price Signals
Provedor de dados: 31
Autores: Araujo,   Claudio; Araujo-Bonjean,   Catherine; Brunelin,   Stephanie.
The aim of this paper is to exploit grain price data to detect the warning signs of looming food crises in Mali, Burkina Faso and Niger. Firstly we identify which markets play a leading role at the national and regional level. The second step consists of identifying crisis periods and characterizing price movements during the period proceeding a crisis. This analysis leads to the identification of early warning indicators whose relevance is tested using panel data qualitative choice models. The results show that monitoring price movements on "leading markets" during crucial periods of the year can help in forecasting future crises.

This study aimed to obtain site-specific and controlled drug release particulate systems. Some particulates were prepared using different concentrations of sodium alginate (Na-Alg) alone and others were formulated using different proportions of Na-Alg with hydroxypropyl methylcellulose (HPMC) stearoxy ether (60M viscosity grade), a hydrophobic form of conventional HPMC, using diclofenac potassium (DP) by ion-exchange methods. Beads were characterized by encapsulation efficiency, release profile, swelling, and erosion rate. The suitability of common empirical (zero-order, first-order and Higuchi) and semi-empirical (Ritger-Peppas and Peppas-Sahlin) models was studied to describe the drug release profile. The Weibull model was also studied. Models were...

Alien species in the Finnish weed flora
Provedor de dados: 21
Autores: Hyvönen, Terho; Jalli, Heikki.
The present study aimed at assessing the invasion of alien weed species in Finland based on a review of their occurrence in the Finnish weed flora. The evaluation was conducted for the three phases of the invasion process, i.e. introduction, naturalization and invasion. The literature review revealed that 815 alien weed species occur in Finland of which 314 are regarded as naturalized. Based on their occurrence in different climate zones, the risk of naturalization of new harmful alien weed species was deemed low for those species not currently found in Finland, but higher for species occurring as casual aliens in Finland. In the latter group, 10 species of concern were detected. Exploration of the distribution patterns of naturalized species within...

Estudou-se o efeito de dietas elaboradas com silagem de grãos úmidos de milho e ácido fumárico sobre os desempenhos de porcas lactantes e suas leitegadas. Foram utilizadas 20 porcas de genética comercial em um delineamento de blocos ao acaso com quatro tratamentos - dieta basal (DB), elaborada a cada 24h; DB + 0,3% de ácido fumárico - (AF); DB + 0,6% AF; e DB + 0,9% de AF, e cinco repetições. As dietas contendo ácido fumárico foram elaboradas a cada 48 horas. O consumo médio diário da dieta das porcas lactantes foi de 7,42kg de matéria natural e não houve diferença (P&amp;gt;0,05) entre os tratamentos. A adição de 0,9% de ácido fumárico às dietas reduziu (P&lt;0,01) em 6% o pH do leite em relação à dieta-basal. A média de ganho diário e a média de peso dos...

Alimentation et déterminisme environnemental de la reproduction des huîtres perlières P. margaritifera sur l'atoll d'Ahe (Archipel des Tuamotu, Polynésie française)
Provedor de dados: 5
Autores: Fournier, Jonathan.
While pearl culture industry represents one of the dominant business sector of French Polynesia, it still entirely relies on natural reproduction and spat collection. A better knowledge of reproduction determinism is thus of particular interest for the black lip pearl oyster P. margaritifera. This work is based (i) on in situ studies of the pearl oyster diet and of the environmental determinism of reproduction; and (ii) on the application to the black lip pearl oyster of a bio-energetic and deterministic model of growth and reproduction based on the Dynamic Energy Budget theory. In Ahe atoll lagoon, plankton concentration and composition fluctuations were strongly linked to wind regimes. These variations had a great impact on the diet of pearl oysters...

Il risultato principale della nostra ricerca ha confermato che la comunicazione degli attributi etici addizionali offre a molte aziende biologiche una reale opportunità di differenziazione dei propri prodotti nel più vasto mercato biologico. Molti consumatori e produttori sono d’accordo sul fatto che la produzione biologica in conformità al regolamento UE sull’agricoltura biologica (834/2007) non rappresenta la ‘fase finale’ in riferimento a una produzione alimentare sostenibile ed etica.  Un numero crescente di consumatori acquista prodotti che siano realizzati secondo standard ‘etici’ non attualmente ricompresi nelle norme previste dal regolamento UE sull’agricoltura biologica o che – in ogni caso – vanno al di là degli standard minimi ivi previsti....

Allee effect in exotic and introduced blowflies
Provedor de dados: 82
Autores: Serra,H; Costa,Mis; Godoy,Wac.
We combined two models to investigate the theoretical dynamics of five exotic and native blowfly species in response to the Allee effect by using demographic parameters estimated from experimental populations. Most of the results suggest stabilization of dynamic behavior in response to the Allee effect. However, the results depended on the magnitude of the demographic parameters of each species, and also indicated chaotic fluctuations and limit cycles. The results are discussed in the context of larval aggregation, an important biological process for blowflies, which naturally incorporates the Allee effect.

Autores: Pradeep Sharma; Pooja Sharma; Manoj Saini; S. S. Singh.
Wheat is one of the most important staple food crops cultivated over 200 mha in the range of environment throughout the world. Wheat production must continue to increase by 2% annually, more particularly in developing world including south-east Asia. Besides increasing the inherent productivity of wheat, it is important to minimize the losses caused to production by various abiotic and biotic factors. Alpha&amp;#x2013;amylase inhibitors are attractive candidates for the control of seed weevils as these insects are highly dependent on starch as the energy source. They play an important role in the carbohydrate metabolism of many heterotrophic and autotrophic organisms. In this study, we aimed to make sequence comparison and phylogenetic relationship among...

The allelic frequencies of 12 short tandem repeat loci were obtained from a sample of 307 unrelated individuals living in Macapá, a city in the northern Amazon region, Brazil. These loci are the most commonly used in forensics and paternity testing. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture for the three parental groups (European, Native American and African) of, respectively, 46%, 35% and 19%. Comparing these allele frequencies with those of other Brazilian populations and of the Iberian Peninsula population, no significant distances were observed. The interpopulation genetic distances (F ST coefficients) to the present database ranged from F ST = 0.0016 between Macapá and Belém to F ST =...

Flowering time in bread wheat (Triticum aestivum L.) is controlled by vernalization and photoperiod response, and earliness per se genes. The genetic basis of flowering time has not been investigated in Pakistani bread wheat. This study was, therefore, conducted to determine the allelic composition at Vrn-A1, Vrn-B1, Vrn-D1, Vrn-B3 and Ppd-D1a loci of 59 Pakistani spring bread wheat cultivars. These cultivars, along with 4 isogenic lines for vernalization genes were characterized with previously reported DNA markers designed for detecting allelic variation at 4 Vrn (Vernalization) and 1 Ppd (Photoperiod) loci. Spring habit Vrn-A1a allele was found in 36% cultivars either alone or with spring habit Vrn-B1 and Vrn-D1 alleles. Two wheat cultivars had the...

Weed suppression is one of the several benefits achieved by soil incorporation of crop residues and such suppression is believed to be allelopathic in nature. The allelopathic potential of different crop residues: viz. sorghum (Sorghum bicolor [L.] Moench), sunflower (Helianthus annuus L.), brassica (Brassica campestris L.) was evaluated in rice (Oryza sativa L.) and jungle rice (Echinochloa colona [L.] Link). Chopped crop residues were soil-incorporated alone and mixed at 6 g kg-1 soil (12 t ha-1) and compared with a control without residues. Soil incorporation of residues substantially delayed germination of jungle rice. The time to start germination, time to 50% emergence, mean emergence time, emergence index, and final germination percentage were all...

The objective of this work was to evaluate the allelopathic potential of aqueous extracts of young and mature leaves from Sapindus saponaria on diaspore germination and seedling growth of barnyardgrass (Echinochloa crus-galli) and morningglory (Ipomoea grandifolia). The aqueous extract was prepared in a proportion of 100 g of dried, ground leaves dissolved in 1000 mL of distilled water, resulting in a 10% extract concentrate. Dilutions of this concentrate were made with distilled water to 7.5, 5.0 and 2.5%. In seedling growth tests, we compared the effect of these extracts with the herbicide nicosulfuron. Both extracts of mature and young leaves caused delays and reductions in diaspore germination and seedling length of barnyardgrass and morningglory, with...

Alliance Formation and Coercion in Networks
Provedor de dados: 31
Autores: Hiller,   Timo.
This paper presents a game-theoretic model of network formation, which allows agents to enter bilateral alliances and to extract payoffs from enemies. Each pair of agents creates a surplus of one, which allies divide in equal parts. If agents are enemies, then the agent with more allies obtains a larger share of the surplus. I show that Nash equilibria are of two types. First, a state of utopia, where all agents are allies. Second, asymmetric equilibria, such that agents can be partitioned into sets of different size, where agents within the same set are allies and agents in different sets are enemies. These results stand in contrast to coalition formation games in the economics of conflict literature, where stable group structures are generally symmetric....

Alliance Performances in the Dutch Biotechnology Sector
Provedor de dados: 31
Autores: Garbade,   Philipp J.P.; Fortuin,   Frances T.J.M.; Omta,   S.W.F. (Onno).
In the biotechnology sector small R&amp;D intensive firms play a fundamental role to keep innovation rates high. With less bureaucratic burdens, low level of hierarchy and high internal flexibility they are able to move fast and to make most efficient use of unique competences. Still their shortage in resources, related to company size, makes them dependent on a strong network of alliances to get access to missing competences and materials. This paper aims at establishing the influence of alliance characteristics on the innovation performance of firms in the biotechnology sector. It presents a conceptual model to clarify the special role of collaboration intensity and how human resource exchange is related to innovation performance of biotechnology...

Allium species poisoning in dogs and cats
Provedor de dados: 80
Autores: Salgado,BS; Monteiro,LN; Rocha,NS.
Dogs and cats are the animals that owners most frequently seek assistance for potential poisonings, and these species are frequently involved with toxicoses due to ingestion of poisonous food. Feeding human foodstuff to pets may prove itself dangerous for their health, similarly to what is observed in Allium species toxicosis. Allium species toxicosis is reported worldwide in several animal species, and the toxic principles present in them causes the transformation of hemoglobin into methemoglobin, consequently resulting in hemolytic anemia with Heinz body formation. The aim of this review is to analyze the clinicopathologic aspects and therapeutic approach of this serious toxicosis of dogs and cats in order to give knowledge to veterinarians about Allium...

ALLOCATING BIOSECURITY RESOURCES IN SPACE AND TIME
Provedor de dados: 31
Autores: Cacho,   Oscar J.; Hester,   Susan M.
Invasive species can cause significant damage to natural environments, agricultural systems, human populations and the economy as a whole. Biological invasions are complex dynamic systems which are inherently uncertain and their control involves allocation of surveillance and treatment resources in space and time. A complicating factor is that there are at least two types of surveillance: active and passive. Active surveillance, undertaken by pest control agencies, has high sensitivity but generally low coverage because of its high cost. Passive surveillance, undertaken by the public, has low sensitivity and may have high coverage depending on human population density. Its effectiveness depends on the extent to which information campaigns succeed in...

Allocation of CAP modulation funds to rural development measures at the regional level in Finland
Provedor de dados: 31
Autores: Hyytia,   Nina.
Further coordination and coherence of the EU funds and policies has been increasingly called for, implying that the territorial perspectives should be included as a major element in the future policies. In this paper, CAP modulation is considered in a framework of a regional development such that it compares the effects on modulation funds first, as they are allocated as income subsidies to farm related, diversified economic activities and second, as they are channeled from agriculture to increased regional investment demand. A rural-urban Social Accounting Matrix is used as a base year data for the CGE-model. The results suggest that transferring CAP payments from actual agriculture as income support to diversified activity does not promote rural...

Allometry and ontogeny in Callibia diana Stål (Mantodea: Acanthopidae)
Provedor de dados: 82
Autores: Avendaño,J; Sarmiento,CE.
The life-cycle of Callibia diana Stål is described and linear and geometric morphometrics are used for studying allometrics and shape changes throughout this neotropical mantid species' life-cycle. Significant changes were expected in the allometry and shape of the raptorial leg and abdomen, given the importance of hunting and reproduction. The allometric slopes were obtained by using total length as the independent variable. Geometric morphometrics of landmarks were used for frontal femur and tibia. Hunting and reproduction-related structures had the steepest slopes and positive allometries. Negative growth of both disc width and head width found in the last moulting event may be a consequence of prothoracic muscle growth which is responsible for...

Autores: Domingos,V.D.; Martins,D.; Costa,N.V.; Marchi,S.R.; Rodrigues-Costa,A.C.
O presente trabalho objetivou avaliar a alocação de biomassa em plantas de Brachiaria subquadripara em função de diferentes concentrações de N, P e K em solução nutritiva. O delineamento experimental utilizado foi inteiramente casualizado, com seis repetições, e os tratamentos constituíram-se de cinco níveis de N, P e K (0, 25, 50, 75 e 100% da concentração na solução-base) durante cinco épocas (intervalos de sete dias). A solução-base utilizada refere-se à diluição de 20% da solução nutritiva para culturas agrícolas. A ausência de N propiciou maior alocação de biomassa em raízes do que em colmos até a quarta semana (28 DAT). A adição de 25 e 75% de fósforo na solução condicionou acréscimos de biomassa de 6,6 e 5,8%, respectivamente, em relação à ausência...

Alterations in DNA repair gene expression and their possible regulation in rat-liver regeneration
Provedor de dados: 74
Autores: Wang,Gai-Ping; Xu,Cun-Shuan.
Rapidly proliferating tissue may require enhanced DNA repair capacity in order to avoid fixation of promutagenic DNA lesions to mutations. Partial hepatectomy (PH) triggers cell proliferation during liver regeneration (LR). However, little is known on how DNA repair genes change and how they are regulated at the transcriptional level during LR. In the present study, the Rat Genome 230 2.0 array was used to detect the expression profiles of DNA repair genes during LR, and differential expression of selected genes was confirmed by real-time RT-PCR. 69 DNA repair genes were found to be associated with LR, more than half of which distributed in a cluster characterized by a gradual increase at 24-72h and then returning to normal. The expression of base excision...

Provedor de dados: 52
Autores: El-Sheekh,Mostafa Mohamed; El-Otify,Ahmed Mohamed; Saber,Hani.
The effect of industrial wastewater on the Nile cyanobacteria Pseudanabaena limnetica and Anabaena wisconsinense was investigated. The data showed that P. limnetica was more sensitive to pollution than A. wisconsinense. The treatments with different levels of wastewater exerted pronounced reductions in protein and amino acids content. SDS-PAGE analysis revealed that the cyanobacteria grown in the industrial wastewater showed induction in the synthesis of certain polypeptides and repression of others. The treatments of P. limnetica with wastewater stimulated the appearance of six protein bands with molecular masses of 28, 30, 31, 32, 58 and 97 kDa. The same treatments caused the disappearance of 20, 38 and 56 kDa. The structural protein pattern of the...

Alternative Insurance Indexes for Drought Risk in Developing Countries
Provedor de dados: 31
Autores: Bobojonov,   Ihtiyor; Sommer,   Rolf.
The paper compares the risk coping potential of insurances that are based on indices derived from weather (rainfall and temperature) data as well as from crop model and remote sensing analyses. Corresponding indices were computed for the case of wheat production in the Aleppo region of northern Syria, representative for agricultural production systems in many developing countries. The results demonstrate that weather derivatives such as the rainfall sum index (RSI) and the rainfall deficit index (RDI) have a very good potential for coping with risk in semiarid areas. Crop simulation model index (CSI) on the other hand could serve as an alternative to RSI and RDI when historical farm yield data is not available or not reliable. In such cases we simulated...

Provedor de dados: 117
Autores: Javaid,Arshad; Ali,Sajjad.
Wild oat (Avena fatua L.) is a problematic weed of wheat (Triticum aestivum L.) in Pakistan. The present study was designed to evaluate the herbicidal activity of culture filtrates of four Trichoderma spp., namely T. harzianum, T. pseudokoningii, T. reesei and T. viride, against this weed species. In a laboratory bioassay, original (100%) and diluted (50%) culture filtrates of T. harzianum and T. pseudokoningii significantly reduced shoot and root growth of A. fatua seedlings. Only original culture filtrates of T. reesei exhibited significant effects, while the effect of filtrates of T. viride was insignificant against shoot and root growth of the target weed species. Generally, original concentrations of culture filtrates of all Trichoderma spp., except...

Alternative pathways for angiotensin II generation in the cardiovascular system
Provedor de dados: 56
Autores: Becari,C.; Oliveira,E.B.; Salgado,M.C.O.
The classical renin-angiotensin system (RAS) consists of enzymes and peptides that regulate blood pressure and electrolyte and fluid homeostasis. Angiotensin II (Ang II) is one of the most important and extensively studied components of the RAS. The beneficial effects of angiotensin converting enzyme (ACE) inhibitors in the treatment of hypertension and heart failure, among other diseases, are well known. However, it has been reported that patients chronically treated with effective doses of these inhibitors do not show suppression of Ang II formation, suggesting the involvement of pathways alternative to ACE in the generation of Ang II. Moreover, the finding that the concentration of Ang II is preserved in the kidney, heart and lungs of mice with an ACE...

The identification of alternative substrates that are suitable for the production of potted plants is very important. To this end, we studied the influence of different substrates on the growth and production of potted chrysanthemum (Dendranthema grandiflora Tzvelev cv. Funny). A completely randomized design with four treatments and twelve replicates was used. Each treatment consisted of the following substrates: i) carbonized rice husks; ii) commercial substrate; iii) mixture of vermiculite and carbonized rice husks in a 1:1 proportion; and iv) mixture of vermiculite and washed sand in a 1:1 proportion. Satisfactory results were obtained with alternative substrates, indicating that rice husks can be used as a sole or partial substrate for potted...

Alternative to Comprehensive Ecosystem Services Markets: The Contribution of Forest-Related Programs in New Zealand
Provedor de dados: 31
Autores: Bhatta,   Arun; Bigsby,   Hugh R.; Cullen,   Ross.
Due to the public goods characteristics of many ecosystem services and their vital importance to human welfare, various mechanisms have been put in place to motivate private landowners in the provision of ecosystem services. A common approach is to try to develop a comprehensive ecosystem services market where landowners can receive payments from beneficiaries of ecosystem services. Much research has been directed at developing methods for valuing the range of ecosystem services so that they can be incorporated into ecosystem services markets. However, valuation methods are difficult, expensive and time consuming. Other approaches to the provision of ecosystem services such as payments for ecosystem services usually focus on a single service like water or...

In organic farming there is an ongoing discussion on piglet castration without anaesthesia and possible alternatives to this practice due to animal welfare concerns. Consumer acceptance of alternatives to piglet castration without anaesthesia plays an important role in this discussion. This contribution examines organic consumers’ attitudes towards piglet castration without anaesthesia and the alternatives castration with anaesthesia and analgesia, immunocastration and fattening of entire males. Additionally, consumers’ willingness-to-pay for the alternatives is determined. The results show that animal welfare, food safety and health concerns influence consumers’ attitudes towards the alternatives. However, the individual perception of those aspects is...

Alternatives for the substitution of synthetic vitamin B2 or vitamin B2 produced from GMOs
Provedor de dados: 21
Autores: Oehen, Bernadette; Früh, Barbara; Schneider, Claudia.
Today in conventional food and feed production added vitamin B2 is produced almost exclusively from a GMO,1 namely the genetically modified Bacillus subtilis. Vitamin B2 applied in certified organic food and feed productions is an exception, as it is still synthesized conventionally. In fall 2007 and also recently, there has been a lack of non-GMO derived vitamin B2 on the European market, which has caused temporary supply problems for organic producers. This event triggered the political will to conduct new research in order to find alternative solutions for the substitution of synthetic vitamin B2 in organic agriculture.

Altimetry combined with hydrography for ocean transport estimation
Provedor de dados: 5
Autores: Gourcuff, Claire; Lherminier, Pascale; Mercier, Herle; Le Traon, Pierre-yves.
A method to estimate mass and heat transports across hydrographic sections using hydrography together with altimetry data in a geostrophic box inverse model is presented. Absolute surface velocities computed from AVISO altimetry products made up of a combination of sea surface height measurements and geoid estimate are first compared to Ship Acoustic Doppler Current Profiler (S-ADCP) measurements of the Ovide project along hydrographic sections repeated every 2 years in summer from Portugal to Greenland. The rms difference between S-ADCP and altimetry velocities averaged on distances of about a hundred km accounts to 3.3 cm s−1. Considering that the uncertainty of S-ADCP velocities is found at 1.5 cm s−1, altimetry errors are estimated at 3 cm s−1....

Autores: Sáenz-Romero,Cuauhtémoc; Beaulieu,Jean; Rehfeldt,Gerald E.
Climatic change will decouple the matching between genotypes and environments. Studying the patterning of genetic variation among pine populations along altitudinal gradients under simulated climatic change temperatures, would provide insights about how to realign the present populations to future environments. Fourteen Pinus patula populations from the forests of the Native Indian Community of Ixtlán de Juárez, state of Oaxaca, México, were collected in January-March 2005 and 2006 along an altitudinal gradient (2400 m to 3050 m, one population every 50 m of altitudinal difference). Seedlings were grown in growth chambers at the Laurentides Forestry Center, Quebec city, Canada, under two temperature treatments aiming to simulate: contemporary temperature...

The tropical legume Acaciella angustissima inoculated with or without Sinorhizobium mexicanum ITTG R7T strain was cultivated in an aluminium (Al) spiked soil to study its tolerance towards this metal. Seedlings of A. angustissima were grown in soil with 0, 2, 4 or 6 mg Al kg-1. The effect of Al and inoculation on growth, nodulation, and nitrogen and tannins content in the plants was monitored. Height and total and dry root weight of plantlets decreased significantly when soil was spiked with Al, but increased when inoculated. Al decreased the number of nodules. Inoculum increased total N and tannin content of the plantlets. It was found that Al reduced the growth of the tropical leguminous N2-fixing shrub A. angustissima, while inoculation with S....

Alzheimer&amp;#x27;s disease is a common neurodegenerative disorder. However, its exact etiology is still unknown. There were several mechanisms proposed such as the tau hypothesis and amyloid hypothesis. However, there is evidence challenging the above two hypotheses. Here, I propose the immune-amyloid hypothesis as a mechanism for Alzheimer&amp;#x27;s disease. Th17 related autoimmunity contributes to the disease pathogenesis. Accumulation of misfolded beta amyloid can trigger heat shock protein which in turn induces TH17 immunity. By microarray analysis of peripheral blood mononuclear cells, there is up-regulation of many TH17 related molecules after Alzheimer&amp;#x27;s disease. After knowing the exact disease pathogenesis, we can develop new...

Autores: Guedron, Stephane; Grimaldi, Michel; Grimaldi, Catherine; Cossa, Daniel; Tisserand, Delphine; Charlet, Laurent.
Total mercury (HgT) and monomethylmercury (MMHg) were investigated in a tropical head watershed (1 km(2)) of French Guiana. The watershed includes a pristine area on the hill slopes and a former gold mined flat in the bottomland. Concentrations of dissolved and particulate HgT and MMHg were measured in rain, throughfall, soil water and at three points along the stream. Samples were taken in-between and during 14 storm events at the beginning and middle of the 2005 and 2006 rainy seasons. Dissolved and particulate HgT concentrations in the stream slightly increased downstream, while dissolved and particulate MMHg concentrations were low at the pristine sub-watershed outlet (median = 0.006 ng L-1 and 1.84 ng g(-1), respectively) and sharply increased at the...

Ambient Endotoxin Concentrations and Assessment of Offsite Transport at Open-Lot and Open-Freestall Dairies
Provedor de dados: 18
Autores: Dungan, R.S.; Leytem, A.B.
Endotoxins are derived from gram-negative bacteria and are a potent inducer of inflammatory reactions in the respiratory tract when inhaled. To assess daily fluctuations of airborne endotoxin and their potential for transport from dairies, endotoxin concentrations were monitored over an 8-h period at upwind (background) and downwind (5 m from edge of dairy) locations on three separate days at two dairies. The dairies consisted of an open-lot or an open-freestall production system, both of which were stocked with 10,000 milking cows.  Upwind concentrations were stable throughout the sampling period, averaging between 1.2 and 36.8 endotoxin units (EU) m-3, whereas downwind concentration averages ranged from 179 to 989 EU-3. Downwind endotoxin concentrations...

Amblyomma dissimile Koch (Acari: Ixodidae) attacking Primolius maracana Vieillot (Psittaciformes: Psittacidae) in the Amazon region, state of Pará, Brazil
Provedor de dados: 82
Autores: Scofield,A; Bahia,M; Martins,AL; Góes-Cavalcante,G; Martins,TF; Labruna,MB.
The tick Amblyomma dissimile Koch feeds preferentially on reptiles (Squamata), although amphibians (Anura) also seem to be important hosts. We report an A. dissimile nymph infesting a blue-winged macaw, Primolius maracana, held in captivity in the Mangal das Garças Park, State of Pará, Brazil. Environmental observations suggest that free-living iguanas (Iguana iguana), which used to walk on the bird enclosure in the park, were the source of the A. dissimile tick that infested the blue-winged macaw. We provide the second world record of a bird host for A. dissimile, and the first bird record for this species in South America.

Autores: Bressoud, Frédérique; Parès, Laure.
L’agriculture biologique repose sur des apports fréquents de matière organique pour maintenir un bon fonctionnement du sol. Ces apports sont particulièrement importants en cas de reconversion de sol en maraîchage, les sols étant dans ce cas généralement appauvris en matière organique. Avec la raréfaction des ressources en fumier, des composts commerciaux conditionnés en bouchon sont fréquemment utilisés, ainsi que depuis quelques années les composts de déchets verts, économiquement très intéressants mais de composition mal connue.   Une expérimentation conduite sur du moyen terme (8 années) à l’INRA d’Alénya a permis de mieux connaître l’évolution des 2 types de compost fréquemment utilisés en système maraîcher sous abri. Ceci permettra  d’optimiser les...

Provedor de dados: 124
Autores: Alencar,Daniel Barroso de; Pires-Cavalcante,Kelma Maria dos Santos; Sousa,Márcia Barbosa de; Viana,Francisco Arnaldo; Saker-Sampaio,Silvana.
Muitas aminas são comumente encontradas em alimentos de origem vegetal e animal, porém apenas um pequeno número é de interesse por produzirem reações adversas se ingeridas e absorvidas no organismo humano. Dentre elas, a histamina e a tiramina podem desencadear sintomas de intoxicação. As algas marinhas são amplamente consumidas pelos povos orientais, e, no Ocidente, seu consumo encontra-se em expansão. O Brasil não tem esta tradição, mas a diversidade de espécies encontradas no litoral brasileiro as torna potencialmente úteis como alimento humano. Para promovê-las com essa finalidade, são necessários estudos químicos e bioquímicos. No presente trabalho, treze espécies de macroalgas marinhas coletadas na praia do Pacheco, no município de Caucaia - CE,...

Autores: Carrera,Constanza Soledad; Reynoso,Cora Marcela; Funes,Gustavo Javier; Martínez,María José; Dardanelli,Julio; Resnik,Silvia Liliana.
The objective of this work was to perform a quantitative analysis of the amino acid composition of soybean seeds as affected by climatic variables during seed filling. Amino acids were determined from seed samples taken at harvest in 31 multi-environment field trials carried out in Argentina. Total amino acids ranged from 31.69 to 49.14%, and total essential and nonessential amino acids varied from 12.83 to 19.02% and from 18.86 to 31.15%, respectively. Variance components expressed as the percentage of total variation showed that the environment was the most important source of variation for all traits, followed by the genotype x environment interaction. Significant explanatory linear regressions were detected for amino acid content regarding: average...

Amino acid features: a missing compartment of prediction of protein function
Provedor de dados: 17
Autores: Esmaeil Ebrahimie; Mansour  Ebrahimi; Mahdi  Ebrahimi.
Enormous computational efforts have been carried out to predict structure and function of protein. However, nearly all of these efforts have been focused on prediction of function based on primary nucleic acid sequence or modeling 3D structure of protein from its nucleic acid sequence. In fact, it seems that amino acid attributes, which is an intermediate phase between DNA/RNA and advanced protein structure, has been missed.&amp;#xd;&amp;#xa;From 2010, we examined the possibility of precise prediction of structural protein function based on amino acid features by improving the following three aspects of amino acid research: (1) Increasing the number of computationally calculated amino acid features, (2) Testing different feature selection (attribute...

Ammonia emissions in tunnel-ventilated broiler houses
Provedor de dados: 89
Autores: Lima,KAO; Moura,DJ; Carvalho,TMR; Bueno,LGF; Vercellino,RA.
Gas production in broiler houses and their emissions are closely related to the microclimate established inside the house according to air temperature, humidity, and velocity. Therefore, the internal house environment is influenced by building typology and ventilation system. The objective of the present study was to evaluate ammonia emission rates in broiler houses equipped with different ventilation systems (negative or positive pressure) and litter conditions (new or built-up). The environment of six commercial broiler houses was evaluated internal and external NH3 concentrations. Ventilation rates were recorded to estimate ammonia emission rates. The efficiency of circulation and exhaust fans was assessed, and higher ventilation rates were determined...

This study examined ammonia excretion at different life stages (eggs, larvae and juveniles) in silver catfish (Rhamdia quelen) and determined the influence of fasting time on ammonia excretion. Eggs and larvae were collected from incubators at different times after fecundation and placed in chambers. Juveniles were separated into two weight classes (2–50 g and 150-320 g) and placed in individual chambers after feeding. Water was collected from each chamber to determine ammonia excretion. Ammonia excretion by the eggs was low, but when hatching began approximately 28h after fecundation, excretion increased until 48h after fecundation. In fasting silver catfish juveniles, there was a significant negative correlation between ammonia excretion and weight....

Ampferkontrolle mittels Heissdampfinjektion
Provedor de dados: 21
Autores: Latsch, Roy; Sauter, Joachim; Kaeser, Alexandra.
A control method for broad-leaved dock (Rumex obtusifolius) with hot steam was tested in grasslands in Switzerland. More than 700 plants were treated with a mixture of hot water and steam at a temperature of 120°C and a pressure of 30 bar. The aim was to identify an optimum heating time, so that the plant mortality rate was more than 80 %. The necessary diesel and water consumption for the heating were measured.   The success of the method is strongly related to the soil moisture. The results show, that the intended mortality rate of 80 % at a soil moisture of 30 % can be realized at a calculated heating time of 30 seconds. For this treatment 2.4 litre of water and 0.046 litre of diesel were needed.

Amylase production by solid-state fermentation of agro-industrial wastes using Bacillus sp.
Provedor de dados: 58
Autores: Saxena,Rajshree; Singh,Rajni.
Solid state fermentation was carried out using various agro- industrial wastes with the best amylase producing strain isolated from soil. Different physicochemical conditions were varied for maximum enzyme production. The strain produced about 5400 units/g of amylase at 1:3 moisture content, 20% inoculum, after 72 h of incubation with Mustard Oil seed cake as the substrate. The optimum temperature and pH of the enzyme activity were found to be 50ºC and 6 respectively. The enzyme was found to be thermostable at 70ºC for about 2 h without any salt. It showed stability at pH range 5-7. The metal ions as Na+, Ca++, Mg++ and Co++ enhanced the enzyme activity.

Autores: Campbell, David; キャンベル, ディビッド.
In this paper I will share a simple four skills activity that can be set up in the Moodle database module that “kills many birds with one stone.” In many activities in the foreign language classroom there are logistical problems that need to be overcome when an instructor wishes to do communicative activities. For example, in a class with a large number of students, 40 or more, it can be difficult and time consuming to create pairs or groups. If you want people to have multiple partners, again there is the problem of moving students around and the delays involved in the process. If the activity is paper based then there is the problem of collecting and redistributing the paper. If the instructor wants to get an idea of the students’ output, there is the...

An adaptive view of caste differentiation in the neotropical wasp Polybia (Trichothorax) sericea Olivier (Hymenoptera: Vespidae)
Provedor de dados: 82
Autores: Desuó,IC; Souza-Galheico,CB; Shima,SN; Santos,GMM; Cruz,J D; Bichara Filho,CC; Dias,CTS.
The tribe Epiponini comprehends the swarm-founding Neotropical wasps, with several species endemic to Brazil, which are extremely important in studies of social evolution of wasps. The Epiponini diverge in several ways from the definitions of high eusociality, since caste syndromes range from species without morphological caste differentiation to those with complete caste dimorphism, and all species are polygynous. Frequently, indirect studies based on morphometry and physiology are the only solutions to collect data regarding the natural history and caste system in this tribe, since most species are extremely aggressive and build enveloped nests, usually in places of difficult access. We analyzed morphological parameters in seven colonies of the Epiponini...

An Agent-Based Model of Exurban Land Development
Provedor de dados: 31
Autores: Chen,   Yong; Irwin,   Elena G.; Jayaprakash,   Ciriyam.
In contrast to urban areas that are aptly characterized by a large population base and scarce land supply, exurban regions have limited households and plentiful land. This basic difference has far reaching implications for spatial equilibrium in exurban land markets. Rather than bidding their maximum willingness-to-pay and reaching a spatial equilibrium in which households are indifferent to location, as is the central condition of urban economic models, we argue that exurban households will be able to retain some amount of surplus in moving to an exurban location and therefore will choose the location that maximizes this locational surplus. In this paper, we first review the handful of structural spatial models of exurban land development that have been...

To insulate farmers against risks in agriculture, government has launched several schemes such as National Agricultural Insurance Scheme and weather index based crop insurance schemes. But their coverage seems to be limited among the farmers primarily due to lack of full information. This paper has reported the results of a survey of 600 farmers conducted to assess their perception about various facets of crop insurance schemes. The Probit and Tobit models have been employed to analyse the factors affecting awareness among the farmers. Crop diversification index has also been used to examine the farmers’ adjustment mechanism against risks. The survey has revealed that most farmers (65%) are aware of risk mitigation measures of the government. But, only...

Autores: Kawata, Yukichika.
In Hokkaido, Japan, the number of Yezo deer (Cervus nippon yesoensis) has recently increased drastically, causing a large number of deer-vehicle traffic accidents. This paper examines conditions related to deer-vehicle traffic accidents by analysing the following relationships: time of accident and lunar phase; time of accidents and time of sunrise/sunset; likelihood of accidents and rainfall patterns, temperature and season (particularly snow and hunting seasons). The results suggest that the potential for deer-vehicle traffic accidents increases during hunting and non-snow seasons when there is little or no rainfall, just before sunrise or just after sunset, or during a full, first quarter, or third quarter moon. A statistically significant relationship...

Autores: Diallo,   Amadou Sekou.
In most developing countries, historically, the main strategy for improving the food sector has focused on increasing farm-level production. But in recent years, with the emphasis on value chain analysis, there has been much more focus on subsector studies, demand-driven approaches, and improving vertical coordination to assure product quality to final consumption markets. Millet, sorghum, and later rice were the traditional leading three cereal crops produced and consumed in Mali. Maize has trailed them for more than two decades, but from mid 1990s on, it has been produced and consumed in much larger quantities. Given the potentials of maize, developing and better organizing its subsector has the potential to not only increase revenues for maize farmers,...

Red algae sulfated polysaccharides (SPs) have been widely described as anticoagulant and antithrombotic agents; however no description of antithrombotic activity regarding green algae SPs has been reported. Caulerpa cupressoides (Chlorophyta) has three different SPs fractions (SP1, SP2 and SP3). We investigated the effects of SP2 on thrombin activity by antithrombin and in an experimental model of venous thrombosis in rats. The inhibition of thrombin assay was evaluated using antithrombin (AT) in the presence of SP2 and the antithrombotic activity was investigated in rats with thromboplastin as the thrombogenic stimulus. The anticoagulant effects of SP2 are suggested be due to the potentiation of thrombin inhibition by antithrombin (IC50 ~ 10.0µg mL-1) and...

An application of the two-stage, semi-parametric approach with double bootstrap to analyze technical efficiency of Critical Access Hospitals
Provedor de dados: 31
Autores: Nedelea,   I. Cristian; Fannin,   James Matthew.
This study examines technical efficiency of Critical Access Hospitals (CAH) using a two-stage approach and bootstrap procedures for making valid inference about the impact of environmental variables on CAH efficiency.  In the first stage, a data envelopment analysis (DEA) efficiency estimator is used to estimate technical efficiency of each hospital in the sample.  In the second stage, efficiency scores are regressed on environmental variables using a truncated regression with bootstrap.  Alternatively, a double bootstrap procedure is used, where bias-corrected DEA efficiency scores, obtained by means of bootstrap in the first stage, are used in the second stage bootstrapped truncated regression.  While both procedures provide valid inference in the second...

Factorial experiments are widely employed in agricultural research. In these experiments, inferences related to the interaction between factors are fundamental. However, many researchers are still unable to analyze this type of experiment, and others do not consider the effect of interaction. This study aims to exemplify a scheme for unfolding the degrees of freedom and to demonstrate the relevance of this rearrangement when the interaction is significant. For these purposes, the response variable time of cooking bean grains was measured in minutes using a completely casualized experimental design, with two replications, arranged in a 2 x 2 x 3 x 2 x 2 factorial scheme (fivefold classification). The following factors were evaluated: bean genotypes (2...

An assessment of competition for biomass resources within the energy and transport sectors
Provedor de dados: 31
Autores: Graham,   Paul W.; Brinsmead,   T.S.; Reedman,   Luke J.
Bio-energy is expected to become increasingly attractive in the future owing to its potential to contribute to lowering greenhouse gas emissions, increasing rural and regional employment and improving energy security through substituting for oil imports. The volume of sustainable biomass resources that are economically competitive but do not significantly impact on food production is expected to slowly expand as new feedstock varieties and refining pathways are developed. However, these volumes will remain limited relative to total energy and transport sector fuel demand. Limited biomass resources will be allocated to the sector that is most able to afford them. This will depend on the price of existing fossil fuel products and the relative cost of...

An Assessment of the Interaction between High Tunnels and Crop Insurance for Specialty Crop Producers
Provedor de dados: 31
Autores: Belasco,   Eric J.; Chen,   Chen; Ponnaluru,   Srinivasa Sasdhar; Galinato,   Suzette P.; Marsh,   Thomas L.
Protective covers, such as high tunnels, are being used by specialty crop producers to enhance production quality and yields, expand or growing seasons, and protect crops from some extreme elements. While growing in popularity, one barrier to larger utilization includes the uncertainty regarding their practices and benefits. This paper recognizes that high tunnels can be used as a form of risk management and examines the relationship with crop insurance in order to better define optimal risk management strategies.

An attempt to modelling revenue insurance schemes at the farm level by means of Positive Mathematical Programming
Provedor de dados: 31
Autores: Severini,   Simone; Cortignani,   Raffaele.
Farmers face increasing income uncertainty and the debate is growing on the role of insurance schemes and of public support in this field. This paper applies a PMP modelling approach that takes into explicit consideration risk aversion behaviour to test its applicability to evaluating the potential impact of insurance schemes. This is done by introducing a revenue insurance scheme into a model developed on a small group of crop farms in Italy. The paper represents a preliminary assessment of the soundness of the proposed approach. It identifies some limitations that should be overcome to improve the proposed approach. Despite these limitations, it seems a useful tool to investigate the impact of insurance schemes and policy relevant parameters such as...

To study which method is more effective in complete compensation and zero compensation for rural land expropriation, we use economic models to analyze whether the government is benevolent and which compensation method can achieve the social optimal level. The results show that both complete compensation and zero compensation will lead to over-investment of land owners, and consequently result in loss of social welfare.

An economic analysis of MGNREG programme has been made in the Mysore district of Karnataka during the year 2009-10. The women participation among total registered workers in MGNREGS has been found significant at 47.8 per cent. Among the total number of works executed under MGNREGS in the sample villages, 96.8 per cent have been natural resource management works and 74.2 per cent community works. More number of natural resource management works are needed to be taken up on individual farmers’ fields to make MGNREGS complementary to agriculture. Among the total participants and non-participants of MGNREGS, 70 per cent in each case were agricultural labourers. In the total income earned by participants and non participants, a major proportion was from...

Soil erosion from construction sites can cause sedimentation of nearby water bodies. Mandatory sediment controls can reduce sedimentation. What determines the degree to which sediment controls meet regulatory standards for installation and maintenance? A conditional-multinomial logit model is estimated with data from 85 construction sites that were audited in 2001 or 2005 in Greenville County, SC to determine whether 147 sediment ponds or traps were installed correctly, properly maintained, or both. Sixty two percent of ponds and traps were installed incorrectly, maintained improperly, or both. Costs of clean out negatively affect the probability that a sediment pond or trap is properly maintained. Construction site distance from the county‘s regulatory...

An economic approach to collective management of endemic animal diseases
Provedor de dados: 31
Autores: Rat-Aspert,   Olivier; Krebs,   Stephane.
The control of animal diseases is an issue of particular interest in animal production chains. Because of their direct impact on production, animal diseases generate income shortfalls for farmers. In some cases, diseases may also have lead to human health problems and undermine market access conditions. Because of these potential negative impacts, some diseases are regulated. But for many communicable diseases, much latitude is given to individual control of the disease by farmers. In the case of a communicable disease, individual management therefore generates an externality, as individual decisions have an impact on the level of risk exposure of other farms to the disease. Thus, the collective result of individual management may differ from the...

An Economic-Psychological Model of Sustainable Food Consumption
Provedor de dados: 31
Autores: Lombardini,   Chiara; Lankoski,   Leena.
This paper proposes a novel economic-psychological model of individual food consumption and food waste that recognizes individuals as social and moral beings who are boundedly rational and have limited capacity for self-control. The model identifies five components of individuals’ utility that correspond to five modes of being or selves: the hedonic agent, the social agent, the moral agent, the health-conscious agent and the habits-driven agent. In the model, individuals maximize this composite utility given their budget and effort constraints. We apply the model to analyze policies that can support the adoption of sustainable food consumption practices.

Stakeholder participation is advocated widely, but there is little structured, empirical research into its influence on policy development. We aim to further the insight into the characteristics of participatory policy development by comparing it to expert-based policy development for the same case. We describe the process of problem framing and analysis, as well as the knowledge base used. We apply an uncertainty perspective to reveal differences between the approaches and speculate about possible explanations. We view policy development as a continuous handling of substantive uncertainty and process uncertainty, and investigate how the methods of handling uncertainty of actors influence the policy development. Our findings suggest that the wider frame...

Autores: Camaioni,   Beatrice; Materia,   Valentina Cristiana.
The aim of the paper is twofold: to present a preliminary analysis of the distribution of the Rural Development (RD) expenditure for specific measures related to human capital across EU and to investigate which factors may explain the variation of intensity of spending between the regions. In particular, a descriptive analysis of the budget and of the expenditure for EU 27 will be presented. A linear regression model (OLS) is also presented in order to verify which factors weigh more in determining the spending decisions for the European regions. The analysis is carried out taking into account the EAFRD expenditures for the measures related to human capital for the period 2007-2008 at NUTS2 level.

Small-scale fisheries, which are often associated with low levels of income and poor infrastructure, receive substantial funding from governmental institutions worldwide. Very few empirical studies have explored the outcomes of these investments for people and ecosystems. This paper presents the findings of a study aimed at assessing the social and ecological outcomes of government subsidies for small-scale fisheries through an analysis of 32 fishing villages, referred to as caletas, in Chile over a 12-year period. Findings suggest that the funding appears to be higher for those caletas with the highest value landings and is unrelated to socioeconomic need or poverty; that caletas in rural areas receive less investment than their urban counterparts; that...

An empirical examination of the gains in cost-effectiveness from the use of multiple environmental outcome conservation tenders
Provedor de dados: 31
Autores: Edwards,   Claire; Eigenraam,   Mark.
The production and consumption of environmental goods and services are subject to many of the problems associated with public goods. Due to their non-rival and non-excludable nature, incentives for individuals to invest in their production are often absent. To address this market failure, government agencies have used a number of policy mechanisms to procure the supply of environmental outcomes on behalf of society. Recently, conservation tenders focussing on private land have been a favoured policy instrument used by many government agencies to purchase environmental outcomes in the public interest. The majority of these environmental tenders have focussed on a single environmental outcome. It is contended in this paper that multiple environmental...

An Empirical Investigation of the Linkages between Government Payments and Farmland Leasing Arrangements
Provedor de dados: 31
Autores: Qiu,   Feng; Goodwin,   Barry K.; Gervais,   Jean-Philippe.
This article investigates the impacts of decoupled and coupled program payments on farmland rental contract choices for a subset of U.S. crop farms using a principal-agent model.We consider cash and share contracts as well as hybrid contracts, which represent an increasingly prominent feature of U.S. agriculture. The conceptual framework suggests that restrictions on payments between contracting parties are ineffective and induce an offsetting contractual rearrangement. Empirical results from a multinomial logit model confirm that government support programs have large, significant effects on contract choices and that these effects vary by types of programs.

An Environmental Trade Case Study: Agricultural Conservation Easement Pays Off Environmental Penalty
Provedor de dados: 31
Autores: Fisher,   Donald A.
Agricultural conservation easements have been traditionally used to transfer or extinguish development rights on farm and ranch land in order to preserve open space and conservation and natural resources. These transfers are typically made with governmental agencies or Internal Revenue Service qualified land trusts. Usually this process is initiated because the property owner wants to ensure future agricultural use as well as conserve natural resources in exchange for financial benefits in either payments and/or tax credits.

An Ethanol Blend Wall Shift is Prone to Increase Petroleum Gasoline Demand
Provedor de dados: 31
Autores: Qiu,   Cheng; Colson,   Gregory; Zhang,   Zibin; Wetzstein,   Michael E.
The US Environmental Protection Agency announced a waiver allowing an increase in the Fuel-Ethanol blend limit (the “blend wall” ) from 10% (E10) to 15% (E15) on October,2010.Justifications for the waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline, leading to energy security. In this paper, employing Monte Carlo simulations and Savitzky-Golay smoothing filter, an empirical study examines this waiver revealing an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are...

An evaluation of changes in stock productivity and consequences for management. An example based on North Atlantic albacore Thunnus alalunga
Provedor de dados: 5
Autores: Kell, Laurence T; Fromentin, Jean-marc.
Reference points are important elements of fisheries management and the supporting scientific advisory frameworks. However, fish stocks can fluctuate extensively over a large range of spatial and temporal scales independent of human exploitation and there has been a classical tendency to assume a dichotomy, i.e., that changes in fish populations are primarily attributable either to exploitation or to environmental variability. Therefore we look at variability in surplus production and examine the relative impacts of the environment and exploitation on the productivity of North Atlantic albacore (Thunnus alalunga). The analysis revealed that variations were driven by environmental effects. It was also found that substantial variations in time-series of...

This paper applies real options theory to establish an overseas oil investment evaluation model that is based on Monte Carlo simulation and is solved by the Least Squares Monte-Carlo method. To better reflect the reality of overseas oil investment, our model has incorporated not only the uncertainties of oil price and investment cost but also the uncertainties of exchange rate and investment environment. These unique features have enabled our model to be best equipped to evaluate the value of oil overseas investment projects of three oil field sizes (large, medium, small) and under different resource tax systems (royalty tax and production sharing contracts). In our empirical setting, we have selected China as an investor country and Indonesia as an...

An ex-ante analysis of distributional effects of the CAP on western German farm incomes
Provedor de dados: 31
Autores: Deppermann,   Andre; Grethe,   Harald; Offermann,   Frank.
This study is concerned with measuring impacts of the Common Agricultural Policy (CAP) on farm income distribution of western Germany. Not only the sheer contribution of market price support and direct payments as a proportion of income is taken into account, but also the impact of support on production incentives. For this purpose, we apply a modelling system consisting of a partial equilibrium model and a programming model. Based on a comparison of Gini coefficients and a decomposition of overall inequality effects we conclude that liberalization of the agricultural sector leads to a more unequal distribution of family farm income in relative terms, whereas a liberalized market provides a more equal situation in absolute terms.

Nanotechnology has come to the attention of food stakeholders in recent years. It offers many potential benefits to food companies and consumers, for example the ability to produce healthier food without compromising taste, but it has also generated much debate, in particular about potential unknown risks associated with food applications of nanotechnology. This research provides some insights into Irish consumer acceptance of food related applications of nanotechnology and details the determining factors framing consumers’ attitudes. Key issues investigated include consumers’ awareness of and attitudes towards nanotechnology, the subjective values (including perceived risk-benefit trade-offs) that frame these attitudes and the influence of new information...

An HPLC-UV method for the measurement of permeability of marker drugs in the Caco-2 cell assay
Provedor de dados: 56
Autores: Kratz,J.M.; Teixeira,M.R.; Koester,L.S.; Simões,C.M.O.
The Caco-2 cell line has been used as a model to predict the in vitro permeability of the human intestinal barrier. The predictive potential of the assay relies on an appropriate in-house validation of the method. The objective of the present study was to develop a single HPLC-UV method for the identification and quantitation of marker drugs and to determine the suitability of the Caco-2 cell permeability assay. A simple chromatographic method was developed for the simultaneous determination of both passively (propranolol, carbamazepine, acyclovir, and hydrochlorothiazide) and actively transported drugs (vinblastine and verapamil). Separation was achieved on a C18 column with step-gradient elution (acetonitrile and aqueous solution of ammonium acetate, pH...

An impact evaluation of technology adoption by smallholders in Sichuan, China: the case of sweet potato-pig systems
Provedor de dados: 31
Autores: Lapar,   Ma. Lucila A.; Ngoc Toan,   Nguyen; Zou,   Chengyi; Liu,   Jinyuan; Li,   Xianglin; Randolph,   Thomas F.
We employ propensity score matching (PSM) framework to examine the impact of sweet potato-based feed technology adoption on household-based pig production in Sichuan, China. An ex post survey in six villages was conducted in 2009, of which five villages were in project intervention sites (exposed area) and one village in the same township but not exposed to project intervention (non-exposed area). We randomly selected 111 households in the exposed areas from the list of households previously interviewed in a baseline survey and 53 households from non-exposed area. Matching estimators such as nearest neighbor matching (NNM), radius matching (RM) and kernel matching (KM) were used to estimate average treatment effects. Results indicate positive net benefit...

An Impact of Atmospheric Anomalies on Zooplankton Communities in the Northern Adriatic and Black Seas
Provedor de dados: 13
Autores: Piontkovski, S.A.; Fonda-Umani, S.; Stefanova, K.; Kamburska, L.; Olazabal, A. De.
The response of the zooplankton community to different types of atmospheric anomalies was analysed by the comparison of sampling series from the Adriatic Sea and the Black Sea. It was shown that the global scale atmospheric anomalies (exemplified by the North Atlantic Oscillation) could affect zooplankton communities entirely. An impact finds its way through the changes in the integrative characteristics of the zooplankton community (i.e. total copepod abundance and total mesozooplankton biomass). The mesoscale atmospheric anomalies (exemplified by the 2003 European Heat Wave) could affect zooplankton communities partially. Changes in integrative characteristics were not well pronounced. Instead, a community has responded through changes in the abundance...

Several extraction methods of genomic DNA for identification and characterization of genetic diversity in different plant species are routinely applied during molecular analysis. However, the presence of undesirable compounds such as polyphenols and polysaccharides is one of the biggest problems faced during the isolation and purification of high quality DNA in plants. Therefore, achievement of fast and accurate methods for DNA extraction is crucial in order to produce pure samples. Leaves of strawberry genotypes (Fragaria ananassa) have high contents of polysaccharides and polyphenols which increase the sample viscosity and decrease the DNA quality, interfering with the PCR performance. Thereby, in this study we evaluated the quality and amount of genomic...

An in vitro study of two GAG-like marine polysaccharides incorporated into injectable hydrogels for bone and cartilage tissue engineering
Provedor de dados: 5
Autores: Rederstorff, Emilie; Weiss, Pierre; Sourice, S.; Pilet, P.; Xie, F.; Sinquin, Corinne; Colliec-jouault, Sylvia; Guicheux, Jerome; Laib, S.
Natural polysaccharides are attractive compounds with which to build scaffolds for bone and cartilage tissue engineering. Here we tested two non-standard ones, HE800 and GY785, for the two-dimensional (2-D) and three-dimensional (3-D) culture of osteoblasts (MC3T3-E1) and chondrocytes (C28/I2). These two glycosaminoglycan-like marine exopolysaccharides were incorporated into an injectable silylated hydroxypropylmethylcellulose-based hydrogel (Si-HPMC) that has already shown its suitability for bone and cartilage tissue engineering. Results showed that, similarly to hyaluronic acid (HA) (the control), HE800 and GY785 significantly improved the mechanical properties of the Si-HPMC hydrogel and induced the attachment of MC3T3-E1 and C28/I2 cells when these...

An index number decomposition of profit change in two Australian fishing sectors
Provedor de dados: 31
Autores: Vieria,   Simon.
Changes in net economic returns in a fishery over time can provide some indication of which direction a fishery’s economic performance is moving. However, without information on the causes of those movements, it is difficult to say if a fishery is moving closer to or further away from a point associated with maximum economic yield. A further complication is that different drivers of profitability can cause profit to move in different directions and at variable magnitudes over time. The key variables that influence a fishery’s profitability include: prices received for catch; prices paid for inputs (such as crew and fuel); vessel productivity (that is, the ability of each vessel to convert its inputs into outputs or harvested catch); and the fishery’s stock...

An individual Based Model of anchovy early life stages in the Bay of Biscay: validation of vertical distribution and growth
Provedor de dados: 5
Autores: Huret, Martin; Petitgas, Pierre; Bourriau, Paul; Grellier, Patrick.
The objective of the study is a better understanding of recruitment variability in anchovy population. An Individual Based Model (IBM) is being developed for the full life cycle of anchovy. The early life stages are presented on this poster. The model is tested in a 1D-vertical framework for validation of the vertical distribution of modelled eggs and larvae against in-situ data. The dynamic Energy Budget (DEB) theory is the biological baseline for individual growth. We test its ability to simulate the observed growth curves between years with contrasted temperatures.

An (in)efficiency based measurement of economic resilience
Provedor de dados: 31
Autores: Mondelaers,   Koen; Lauwers,   Ludwig H.
The ecosystem and the economic subsystem are interlinked. In fact, it is the overconsumption of scarce resources or the overproduction of bad outputs at economic system level that causes a great part of the imbalances at the ecosystem level. Some imbalances do not originate at the economic system level, but are due to external factors. Given the possibility of external shocks, respecting static sustainability thresholds is not a guarantee for system sustainability. In a dynamic setting, the concept of resilience is therefore helpful. In this paper we show how this concept can complement the traditional efficiency approach to come to a sustainable value creating economic system.

Autores: Carillo,Maria; Formato,Andrea; Fabiani,Andrea; Scaglione,Giampiero; Pucillo,Giovanni Pio.
Background: With this research an inertizing and cooling process for grapes cryomaceration has been set up. The process in question has been performed by an innovative plant that cooled the grapes rapidly in about 8 sec until they reached the set cryo-maceration temperature, using direct injection of liquid CO2. It works with a grape flow of approximately 2-3 tons/h, with a maximum thermal gradient of 20 K between the grape inlet and outlet temperature. For this plant a vibrating device was set up that allowed that only one grape cluster layer to be formed on the ribbon conveyor after the grapes had been put into the feedbox. A numerical model was set up for the cooling tunnel, and numerical simulations were performed to investigate the operative...

AN INITIAL INVESTIGATION OF THE POTENTIAL FOR HERMETIC PURDUE IMPROVED CROP STORAGE (PICS) BAGS TO IMPROVE INCOMES FOR MAIZE PRODUCERS IN SUB-SAHARAN AFRICA
Provedor de dados: 31
Autores: Jones,   Michael; Alexander,   Corinne E.; Lowenberg-DeBoer,   James.
Pests like the larger grain borer (P. truncatus) and the maize weevil (S. zeamis) cause significant storage losses for African maize producers.  The value of storage protection to a market-oriented farmer is a function of price seasonality, value loss prevention, and their opportunity costs of capital.  Evidence suggests that hermetic technologies like Purdue Improved Crop Storage (PICS) bags can be effective against these key maize storage pests, but sustainable technology transfer requires that it be profitable for producers. This analysis references dry weight loss figures from key life science articles and builds on previous value loss research to provide a geographic model for potential storage technology adoption.  PICS bag profitability with one and...

This is the first record on the invasion of the Neotropical brown stink bug, Euschistus heros (F.) in Paraná County (latitude 31º 51' 9.6" S, longitude 60º 32' 11.2" W), Entre Ríos province, Argentina. Five adults were intercepted in 2009/2010, one in crop residues and four on soybean fields. The expanding range in the distribution of E. heros in the Southern Hemisphere is believed to be due to the increased commercial trade among countries, increase in the area cultivated with soybean, and the adoption of no-tillage cropping systems.

The impact of the fishing effort exerted by a vessel on a population depends on catchability, which depends on population accessibility and fishing power. The work investigated whether the variation in fishing power could be the result of the technical characteristics of a vessel and/or its gear or whether it is a reflection of inter-vessel differences not accounted for by the technical attributes. These inter-vessel differences could be indicative of a skipper/crew experience effect. To improve understanding of the relationships, landings per unit effort (lpue) from logbooks and technical information on vessels and gears (collected during interviews) were used to identify variables that explained variations in fishing power. The analysis was undertaken by...

An Iterative Auction for Spatially Contiguous Land Management: An Experimental Analysis
Provedor de dados: 31
Autores: Banerjee,   Simanti; Shortle,   James S.; Kwasnica,   Anthony M.
Tackling the problem of ecosystem services degradation is an important policy challenge.  Different types of economic instruments have been employed by conservation agencies to meet this challenge. Notable among them are Payment for Ecosystem Services (PES) schemes that pay private landowners to change land uses to pro-environmental ones on their properties. This paper focuses on a PES scheme – an auction for the cost-efficient disbursal of government funds for selection of spatially contiguous land management projects. The auction is structured as an iterative descending price auction where every bid is evaluated on the basis of a scoring metric – a benefit cost ratio. The ecological effectiveness and economic efficiency of the auction is tested with data...

A.N. Kolmogorov's defence of Mendelism
Provedor de dados: 74
Autores: Stark,Alan; Seneta,Eugene.
In 1939 N.I. Ermolaeva published the results of an experiment which repeated parts of Mendel's classical experiments. On the basis of her experiment she concluded that Mendel's principle that self-pollination of hybrid plants gave rise to segregation proportions 3:1 was false. The great probability theorist A.N. Kolmogorov reviewed Ermolaeva's data using a test, now referred to as Kolmogorov's, or Kolmogorov-Smirnov, test, which he had proposed in 1933. He found, contrary to Ermolaeva, that her results clearly confirmed Mendel's principle. This paper shows that there were methodological flaws in Kolmogorov's statistical analysis and presents a substantially adjusted approach, which confirms his conclusions. Some historical commentary on the Lysenko-era...

In 1995, a pioneering MD-PhD program was initiated in Brazil for the training of medical scientists in experimental sciences at the Federal University of Rio de Janeiro. The program’s aim was achieved with respect to publication of theses in the form of papers with international visibility and also in terms of fostering the scientific careers of the graduates. The expansion of this type of program is one of the strategies for improving the preparation of biomedical researchers in Brazil. A noteworthy absence of interest in carrying out clinical research limits the ability of young Brazilian physicians to solve biomedical problems. To understand the students’ views of science, we used qualitative and quantitative triangulation methods, as well as...

Autores: Duffa, Celine; Dufois, Francois; Coudray, Sylvain.
As part of its development of post-accident management tools, the French Institute for Radiological Protection and Nuclear Safety is setting up a model to simulate radionuclide dispersion in the Toulon marine area (one of France's main military ports). The model is based on the MARS 3D code developed by IFREMER. It reproduces hydro-sedimentation phenomena in the Bay of Toulon with a horizontal spatial resolution of 100 m and 30 vertical sigma levels and also factors in radioactive decay and dissolved/particulate distribution of the radionuclides studied. With no tide, the major currents in this area are generated by the wind. The model effectively reproduces the resulting hydrodynamic phenomena, which were measured throughout the summer of 2009 in the...

An Optimal Rule for Switching over to Renewable fuels with Lower Price Volatility: A Case of Jump Diffusion Process
Provedor de dados: 31
Autores: Sardana,   Kavita; Bhattacharya,   Subhra K.
This study investigates the optimal switching boundary to a renewable fuel when oil prices exhibit continuous random fluctuations along with occasional discontinuous jumps. In this paper, oil prices are modeled to follow jump diffusion processes. A completeness result is derived. Given that the market is complete the value of a contingent claim is risk neutral expectation of the discounted pay off process. Using the contingent claim analysis of investment under uncertainty, the Hamilton-Jacobi-Bellman (HJB) equation is derived for finding value function and optimal switching boundary. We get a mixed differential-difference equation which would be solved using numerical methods.

The 450-million-year-old interaction between the majority of land plants and mycorrhizal fungi is one of the most ancient, abundant, and ecologically important symbiosis on earth. The early events in the evolution of mycorrhizal symbioses seem to have involved reciprocal genetic changes in ancestral plants and free-living fungi. new data on the mechanism of action of specific signaling molecules and how it influence and is influenced by the membrane ions fluxes and cytoplasm ion oscillations which integrate the symbiotic ionome are improving our understanding of the molecular bases of the mycorrhization process.

Alien plants are known to occur in Brazil since the 18th century when African grasses started to be recorded in pastures near Rio de Janeiro. In the beginning of the 19th century two royal decrees (July, 1809 and July, 1810) offered grants and tax exemption to everyone who would introduce plants of economic value. Nowadays, there are 117 plant species recognized as invasive or established and with invasive potential in Brazil and an unknown number of introduced plant species. Some of the most pervasive invasive species are Artocarpus heterophyllus Lam. and Hedychium coronarium König in tropical ombrophilous forest, Hovenia dulcis Thunb. in subtropical ombrophilous forest and subtropical semi-deciduous forest, Pinus taeda L. and Pinus elliottii Engelm. in...

An overview of the development challenges and constraints of the Niger Basin and possible intervention strategies
Provedor de dados: 31
Autores: Namara,   Regassa E.; Barry,   Boubacar; Owusu,   Eric S.; Ogilvie,   Andrew.
The Niger River Basin covers 7.5% of the African continent and is shared between nine riparian countries. The human population of the basin is growing at an average annual rate of about 3%, which makes the Niger River Basin one of the areas with the highest fertility rates in the world. The desert margin is expanding; climate change is negatively impacting rainfall; and urbanization, industrialization, and the human and livestock population are threatening the quantity and quality of available water resources. The basin population already suffers from chronic poverty. Based on a literature review, this paper suggests some key water-related and other interventions that are capable of easing the basin's development challenges.

The Bacteria Domain experienced an explosion of novel lineages identified within the last decade, especially of lineages made entirely of uncultured members. Since numerous cultivable bacteria have been shown to be instrumental in human development, health, and diseases, it is reasonable to speculate that strains from uncultured groups, which comprise nearly 80% of the human gut and 68% of human oral microbial consortia, participate in similar functions. The study of human-associated uncultured bacteria, however, has many practical limitations, such as access to patient samples, unpredictable microbial composition, and low relative abundance, all of which challenge experimental promptness and reproducibility. We propose that uncultured bacteria from...

An Unusual Anatomic Variation of the Jugular Foramen with Doubled Posterior Condylar Canal
Provedor de dados: 77
Autores: Kapakin,Samet.
A case of unusual anatomical variation of the jugular foramen (JF) with doubled posterior condylar canal (PCC) is reported. According to the presence of bridging, the JF can be defined as Type I (one septation, two compartments) on the right side and Type IV (three septations, four compartments) on the left side. The dome of the jugular fossa is present on the right, absent on the left. The jugular foramen shows a canal-like structure with an external and an internal opening. The lengths of the longest and widest axes of the JFs are measured as 21.93 x 16.56 mm on the right and 16.75 x 15.14 mm on the left side. The right JF is larger. The PCC is doubled on the right side and there is only one on the left side. It is essential not only to know compartments...

An unusual, dwarf new species of Neotropical freshwater stingray, Plesiotrygon nana sp. nov., from the upper and mid Amazon basin: the second species of Plesiotrygon (Chondrichthyes: Potamotrygonidae)
Provedor de dados: 84
Autores: Carvalho,Marcelo R. de; Ragno,Maíra P.
A new species of the relatively poorly known Neotropical freshwater stingray genus Plesiotrygon Rosa, Castello &amp;amp; Thorson, 1987 is described from the main channel and smaller tributaries (Ríos Itaya and Pachitea) of the upper Amazon basin in Peru. The first specimen to be collected, however, was from much farther east in Rio Solimões in 1996, just down-river from Rio Purus (specimen unavailable for this study). Plesiotrygon nana sp. nov., is a very distinctive and unusually small species of freshwater stingray (Potamotrygonidae), described here mostly from three specimens representing different size classes and stages of sexual maturity. Plesiotrygon nana sp. nov., is distinguished from its only congener, P. iwamae Rosa, Castello &amp;amp; Thorson,...

An unusual reproductive mode in Hypsiboas (Anura: Hylidae)
Provedor de dados: 103
Autores: Moura,Mário Ribeiro de; Motta,Ana Paula; Feio,Renato Neves.
We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles. Herein, the bromeligenous behavior is reported for the first time in Hypsiboas Wagler, 1830. Although this reproductive behavior has been observed more than once here, we believe that it is not typical of Hypsiboas, being better characterized as an unusual reproductive mode for Hypsiboas, indicating the presence of plasticity in the reproductive modes of H. pardalis

An Update on the Consequences of EU Sugar Reform
Provedor de dados: 31
Autores: Moyo,   Sibusiso; Spreen,   Thomas H.
Since its formation the European Union (EU) has employed a rather complicated policy to ensure high prices to domestic sugar growers and trade preferences to certain sugar exporting countries, e.g. the African Caribbean and Pacific (ACP) group. One result of this policy is that the EU has been both the second largest importer and second largest exporter in the world market. Under pressure from the World Trade Organization (WTO), the EU agreed to reform its policies toward sugar in 2001, with the full effect of the reforms being fully implemented in 2006. In this paper, the impact of the sugar reform on EU production, consumption, imports, and exports is examined especially with regard to how it all affects the ACP countries who receive preferential...

An updated climatology of surface dimethlysulfide concentrations and emission fluxes in the global ocean
Provedor de dados: 5
Autores: Lana, A.; Bell, T. G.; Simo, R.; Vallina, S. M.; Ballabrera-poy, J.; Kettle, A. J.; Dachs, J.; Bopp, L.; Saltzman, E. S.; Stefels, J.; Johnson, J. E.; Liss, P. S.
The potentially significant role of the biogenic trace gas dimethylsulfide (DMS) in determining the Earth's radiation budget makes it necessary to accurately reproduce seawater DMS distribution and quantify its global flux across the sea/air interface. Following a threefold increase of data (from 15,000 to over 47,000) in the global surface ocean DMS database over the last decade, new global monthly climatologies of surface ocean DMS concentration and sea-to-air emission flux are presented as updates of those constructed 10 years ago. Interpolation/extrapolation techniques were applied to project the discrete concentration data onto a first guess field based on Longhurst's biogeographic provinces. Further objective analysis allowed us to obtain the final...

Anaerobic digestion as a tool to eliminate animal parasites and weed seeds
Provedor de dados: 21
Autores: Johansen, Anders; Hansen, Christian M.; Andreasen, Christian; Carlsgart, Josefine; Nielsen, Henrik Bangsø; Roepstorff, Allan.
Anaerobic digestion of residual materials from animals and  crops offers an opportunity to simultaneously produce bioenergy and plant fertilizers at single farms and in farm communities where input substrate materials and resulting digested residues are shared among member farms. A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pest like animal parasites, pathogens, and weed seeds. In the BIOCONCENS project (http://www.icrofs.dk/Sider/Forskning/foejoIII_bioconcens.html) batch experiments were performed, where survival of six species of weeds and the pigs large roundworm Ascaris suum (non-embryonated eggs) was assessed under conditions similar to biogas plants managed at meso- (37°C) and thermophilic (50°C)...

Autores: Silva,Vicente P. R. da; Pereira,Emerson R. R; Azevedo,Pedro V. de; Sousa,Francisco de A. S. de; Sousa,Inajá F. de.
Os dados diários de chuva de 600 estações meteorológicas foram analisados para avaliar a variabilidade da pluviometria na região Nordeste do Brasil. No estudo foram construídos mapas do número de dias chuvosos, do coeficiente de variação (CV) da precipitação pluvial e do número de dias chuvosos. A análise de correlograma também foi aplicada aos totais anuais da precipitação pluvial na região. Os resultados evidenciam que as áreas do semiárido da região de estudo têm os maiores valores de CV da precipitação pluvial e do número de dias chuvosos que as áreas localizadas no litoral e agreste. Os maiores valores de coeficiente de variação estão associados aos menores valores de precipitação pluvial e ao número de dias chuvosos. A variabilidade da precipitação...

Análise de um projeto agroindustrial utilizando a Teoria de Opções Reais: a opção de adiamento
Provedor de dados: 123
Autores: Nardelli,Paula Moreira; Macedo,Marcelo Alvaro da Silva.
O objetivo geral deste trabalho é analisar a viabilidade econômico­financeira de um projeto agroindustrial, através da Teoria de Opções Reais (TOR). A justificativa para utilização da TOR está centrada no fato de que os métodos tradicionais de análise de projetos (VPL e TIR) ignoram duas características importantes: a) a irreversibilidade e b) a possibilidade de adiamento da decisão de investir. Essas características, junto à incerteza sobre o futuro, fazem com que a oportunidade de investimento seja análoga a uma opção financeira. Com o intuito de aplicar estes conceitos, será realizado um estudo de caso, que consiste em um projeto agroindustrial de processamento de frutas, em que se pretende produzir sucos, polpas, geleias, doces e frutas desidratadas.

Quanto mais complexo for o ambiente que envolve o processo decisório, mais difícil este último se torna, uma vez que aumenta o número de variáveis a serem analisadas, bem como as relações possíveis entre as variáveis. No ambiente dos agronegócios o panorama observado não parece ser diferente. O objetivo deste estudo foi aplicar, em um estudo de caso (cadeia produtiva do biodiesel do Rio Grande do Sul), uma estrutura analítica desenvolvida para a análise de processos decisórios no agronegócio, visando verificar a existência de inter-relação teórica nos pressupostos utilizados e se a estrutura teórica se confirmava por meio da existência de correlações. Utiliza-se na base teórica: a) modelo de tomada de decisão de Simon (1977); b) especificidades presentes...

Dezesseis vacas mestiças Holandês × Zebu (grau de sangue variando de ½ a ¾ Holandês × Zebu) foram distribuídas segundo quatro quadrados latinos 4 × 4 para se avaliar a viabilidade econômica do aumento do nível de concentrado na dieta. As vacas de terceira ou quarta lactação, com produção anterior entre 2.500 e 3.000 kg, ajustada para 300 dias, foram manejados a pasto na época das águas, e com 110 dias de lactação no início do período experimental. Com os preços do leite e concentrado praticados no momento do estudo, não é interessante a utilização de concentrado na dieta de vacas leiteiras alimentadas com cana-de-açúcar. Contudo, considerando os aspectos produtivo e econômico conjuntamente, e os preços de R$ 0,70 e R$ 0,50 para o leite e o concentrado,...

Análise multivariada da divergência genética de genótipos de arroz sob estresse salino durante a fase vegetativa
Provedor de dados: 124
Autores: Benitez,Letícia Carvalho; Rodrigues,Isabel Corrêa da Silva; Arge,Luis Willian Pacheco; Ribeiro,Márcia Vaz; Braga,Eugenia Jacira Bolacel.
A salinidade, dos solos e da água de irrigação, constitui fator limitante para o cultivo do arroz, principalmente nos estágios iniciais do desenvolvimento e no período de floração. A utilização de fontes de água de má qualidade para irrigação resulta no acúmulo de sais no solo, causando toxicidade importante na cultura. Uma solução para o problema seria a introdução de variedades com tolerância à salinidade elevada. Assim, objetivou-se com este trabalho avaliar a divergência genética entre genótipos de arroz visando à seleção de genótipos tolerantes à salinidade durante a fase vegetativa. Sementes de 10 genótipos de arroz foram cultivadas in vitro, em meio MS acrescido de 0 e 136 mM de NaCl. Após 21 dias, foram avaliados seis caracteres morfológicos e os...

Análise termogravimétrica do óleo essencial de pimenta longa (Piper hispidinervium C. DC)
Provedor de dados: 36
Autores: Cremasco,Marco Aurelio; Nazareno,Braga Pina.
A pimenta longa (Piper hispidinervium C. DC.) é um arbusto originário da região amazônica, cujo óleo essencial é rico em safrol. O óleo essencial da pimenta longa é comercializado in natura, o que faz o processamento para a obtenção do safrol elemento fundamental de investigação científica e tecnológica. Uma importante etapa para a obtenção do safrol é a definição da estratégia da sua separação do óleo essencial a partir, por exemplo, da destilação. Neste caso, torna-se essencial o conhecimento de parâmetros termodinâmicos, tais como energia de ativação e calor latente de vaporização. Neste trabalho é utilizada a técnica termogravimétrica para a obtenção dos valores da energia de ativação e calor latente de vaporização do óleo essencial de P....

Provedor de dados: 32
Autores: Silva Pérez, Viridiana.
El maíz (Zea mays L.) es el cultivo básico más importante en México, y en los últimos años se ha secuenciado su genoma. En este trabajo se utiliza parte de la información genómica, 2,039 marcadores moleculares y se relaciona con el contenido de carotenos en líneas endogámicas recombinantes de maíz de la cruza B73 × Mo17  (IBM-RILs) para detectar loci de caracteres cuantitativos (QTLs). En la primera fase, se estudió el contenido de carotenos en las hojas, ya que éstos disipan la energía lumínica utilizada en la fotosíntesis, influyendo así en la tasa fotosintética y en el rendimiento de los cultivos. Se midió el contenido de luteína, β-caroteno, α-caroteno, β-criptoxantina y zeaxantina, y se encontró que β-caroteno representó 80% del total de carotenos. Se...

Análisis de alternativas para la eliminación de la sobreexplotación de acuíferos en el Valle de Guadalentín
Provedor de dados: 31
Autores: Calatrava-Leyva,   Javier; Guillem,   Amanda; Martinez-Granados,   David.
In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical programming model that maximises the farm net margin resulting from the use of the available water resources for irrigation in the area. Our results show that the buyback of groundwater pumping rights is the option with the greatest public budgetary cost and economic impact. On the contrary, the combination of an environmental tax on groundwater pumping and the substitution of groundwater by subsidised desalinised water allow eliminating aquifer overdraft in the area while...

The impacts of biofuel-based commodity price shocks on wheat and maize producers and consumers in Mexico are quantified with a two-region welfare economics model of the world wheat and maize markets. This model captures the international flow of wheat and maize between Mexico and the rest of the world, enabling measurement of price and quantity changes in both Mexican and global wheat and maize markets due to supply shocks in the grain markets. The drastic shifts in supply that accompanied grain markets in 2007/2008 are used to quantify the effects on Mexican consumer and producer well-being.

Autores: Abbott,L.; Pistorale,S.
Trece genotipos de Bromus catharticus se evaluaron, durante 3 años, utilizando un diseño experimental completamente aleatorizado con seis repeticiones. Por planta individual se analizaron el número de panojas, el número de semillas y el peso de 1000 semillas. La interacción genotipo x ambiente fue estadísticamente significativa e indica un comportamiento diferencial de los genotipos evaluados a través de los años. Una vez comprobada la interacción, se aplicaron tres metodologías para evaluar la estabilidad y adaptabilidad de los genotipos: la ecovalencia de Wricke, el índice de Lin &amp;amp; Binns y el modelo de Eberhart &amp;amp; Russell. Estas dos últimas metodologías coinciden en identificar como estables y adaptables a los mismos genotipos para los...

El nitrógeno (N) es uno de los elementos más importantes para la nutrición de las plantas, por lo cual es necesario tener métodos rápidos y confiables para determinar N en el suelo. El objetivo del presente estudio fue predecir la concentración de nitrógeno total (Nt) en suelos de una región tropical de México mediante espectroscopia de infrarrojo cercano (NIRS), en muestras dentro de una bolsa de polietileno y sin ésta. La ventaja de usar NIRS reside en la gran selectividad de la técnica para cuantificar un elemento químico en una mezcla compleja sin trabajo previo de separación. Además permite evaluar la cantidad de Nt en pocos minutos en muestras de diferentes suelos. En el trópico húmedo de Tabasco, México, se seleccionaron 156 muestras de suelo con...

Provedor de dados: 32
Autores: Flores Sánchez, Jorge Luis.
En México, el HLB inducido por ´Candidatus Liberibacter asiaticus´ (CLas) se detectó en Yucatán, en 2009. Debido al carácter devastador de esta enfermedad y que México es el principal productor de cítricos agrios, es necesario cuantificar el efecto de CLas en producción comercial. Este trabajo tuvo como objetivo estimar pérdidas productivas inducidas por CLas en limón persa (Citrus latifolia) mediante la evaluación de variables morfológicas y organolépticas. En Tizimin Yucatán, árboles de cuatro años de limón persa se seleccionaron por su condición de manejo y enfermedad verificada por PCR cuantitativo. Ocho variables morfológicas y organolépticas se evaluaron en un diseño de bloques con tratamientos apareados. Los valores de peso, tamaño, grosor de...

Análisis numérico del clima interior en un invernadero de tres naves con ventilación mecánica
Provedor de dados: 115
Autores: Flores-Velázquez,Jorge; Mejía-Saenz,Enrique; Montero-Camacho,Juan I.; Rojano,Abraham.
Uno de los principales problemas que enfrenta la agricultura en invernaderos, sobre todo en regiones de clima cálido, es moderar y controlar los problemas derivados del incremento de temperatura que ocurre en marcados periodos del año, ya que reducen la calidad y cantidad de la cosecha. Un método efectivo para el control del clima es la ventilación (natural o forzada) y aunque la ventilación forzada sea más predecible que la natural, su descripción es compleja y una simplificación obliga un mayor conocimiento del proceso. El objetivo de este trabajo fue validar y aplicar un modelo numérico basado en la dinámica de fluidos computacional (CFD) para el análisis climático de un invernadero cenital de tres naves sin cultivo y con ventilación forzada....

Deutschland ist nicht nur größter Absatzmarkt, sondern auch größter Produzent von Bio-Produkten in Europa. Trotzdem hat der deutsche Handel im Wirtschaftsjahr 2009/2010 je nach Produkt 2 bis 95 Prozent der abgesetzten Produkte, die auch von deutschen Erzeugern hätten produziert werden können, importiert. Dies zeigt dieses Projekt, welches Befragungsergebnisse, Haushaltspaneldaten, Produktions- und Flächendaten sowie Export- und Importmengen zusammengeführt und analysiert hat.  Ein überraschendes Ergebnis war der niedrige Importanteil von Getreide mit 15 Prozent. Von Weizen allerdings kamen 21 Prozent der Partien aus dem Ausland. Der Anteil variiert je nach Menge und Qualität der deutschen Ernte, jedoch besteht in Rumänien, Russland und der Slowakei noch...

Fodder production requires the highest energy input in dairy farming. Taking the  organic and conventional dairy farms from the project “climate effects of land use systems – evaluations on pilot farms” as an example we analyse the energy input for producing different fodder types and the influence of feeding strategies in Southern Germany. The results show that grazing is the most energy efficient form of feeding, followed by fresh grass and silage. Hay requires the highest energy input per unit forage energy. Maize silage has a lower energy input due to high yields. The higher the part of roughage in the ration the lower is the energy input for production of the ration.

Autores: Deneuville, Laurence.
Grâce à une enquête postale auprès de 1278 agriculteurs situés dans la région PACA, nous analysons les bénéfices non économiques de l’agriculture biologique (AB). L’analyse des réponses individuelles (N=267) démontre que pour la majorité de ces bénéfices, une proportion non négligeable des agriculteurs a choisi le niveau élevé. En revanche, la plupart des agriculteurs estiment que leur travail n’est pas reconnu à sa juste valeur par la société et par les autorités publiques. En outre, notre estimation économétrique (modèle probit bivarié)montre que le fait d’être en AB augmente la probabilité que les agriculteurs choisissent des niveaux élevés de satisfaction (personnelle et au travail) et favorise l’autonomie et le sentiment d’être en phase avec ses...

Analysis of Changes in Energy Consumption and Demand Trend in China’s Agricultural Production
Provedor de dados: 31
Autores: Zhu,   Li-zhi; Liu,   Jing; Xu,   Ran; Xiang,   Meng.
China’s energy consumption for agricultural production has relied on petroleum and coal with relatively low input from power and other types of energy for a long time. Projections indicate that as China’s existing development trend leads to substantial growth of energy demand for agricultural production, such a long term irrational energy consumption pattern would unlikely be able to meet the needs of the country’s developing agricultural sector. As such, it is recommended that China’s agricultural sector should follow the national energy development strategy guideline by gradually increasing the use of wind power, solar energy, biomass and other new energy sources while advancing technological innovations on traditional energy sources. Meanwhile, as the...

To this end, the proposal is an analysis of the reasons for choosing to consume this type of food or not, accompanied by a supplementary investigation, mostly to assess the relationship between consumption patterns and willingness to pay (WTP) for the most common categories of functional foods, such as milk fortified with CLA (conjugated linoleic acid). Our research shows that a proportion of the population is unaware of the existence of functional foods and their properties. Moreover, it shows that when the concept of functional foods is explained to consumers, this creates a greater willingness to pay for such food, which is strongly linked to...

Provedor de dados: 31
Autores: Chern,   Wen S.; Lin,   Huei-Ching.
This study attempts to evaluate the economic benefits of the country of origin labeling (COOL) in Taiwan.  A Vickrey second-price sealed-bid auction was conducted to estimate the consumer’s willingness to pay for Taiwan products vs. those from China and Vietnam. Our experiment was designed to investigate the impacts of product tasting on bidding behavior. The regression results show that tasting raised bids for Taiwan and China teas, but lowered bids for Vietnam tea. The econometric results show very high premiums for Taiwan products. Taiwanese consumers and food producers stand to benefit greatly with COOL.

Polybia scutellaris (White, 1841) is a social wasp of biological interest for its role as pollinator and maybe as biological control agent of sanitary and agricultural pests. This study examines the digestive tract contents of the larvae of P. scutellaris from four nests in Magdalena (Buenos Aires province, Argentina). Contents included both animal (arthropod parts) and plant (pollen, leaf and fruit epidermis) parts. The pollen content analysis showed that the wasps visited 19 different taxa of plants during the last active period of the colony before the nests had been collected. The range of sources used by P. scutellaris allows us characterizing the species as a generalist flower visitor. Wasps visited both native and exotic plants located nearby the...

Analysis of Elderly In-Migrants In Tennessee
Provedor de dados: 31
Autores: Zhou,   Xia (Vivian).
The idea of elderly in-migrants as an important factor or stimulus to local economic development (Serow, 2001) has been confirmed by quite a few studies such as Bennett (1993); Carlson, Junk, Fox, Rudzitis, &amp; Cann (1998); Day &amp; Barlett (2000); Hodge (1991); Serow &amp; Haas (1992); and Stallmann, Deller, &amp; Shields (1999).  Large-scale elderly in-migrants can bring several benefits to local economy.  First, they can increase property and sales taxes, counties' largest source of revenues, without directly increasing their greatest expense such as public education; also, in-migrant retirees as a large portion of elderly do not compete for jobs so that most of counties consider them as net economic assets (Day &amp; Barlett, 2000; Glasgow, 1991;...

In the United States, biomass is the largest source of renewable energy accounting for over 3 percent of the energy consumed domestically and is currently the only source for liquid, renewable, transportation fuels. Continued development of biomass as a renewable energy source is being driven in large part by the Energy Independence and Security Act of 2007, which mandates that by 2022 at least 36 billion gallons of fuel ethanol be produced, with at least 16 billion gallons being derived from cellulose, hemi-cellulose, or lignin. However, the market for cellulosic biofuels is still under development. As such, little is known about producer response to feedstock prices paid for dedicated energy crops. While there have been some studies done on factors that...

Analysis of Flue-cured Tobacco Supply Elasticity in Zimbabwe 1980-2010: An Error Correction Model Approach
Provedor de dados: 31
Autores: Pfumayaramba,   Tichaona.
Flue cured tobacco has been an important crop for the Zimbabwean economy historically in terms of foreign currency earnings and employment creation. Between 1980 and 2000, there is a general increase in tobacco output, followed by a sharp decline from 2001 up to 2008 and then output starts to increase again. Flue cured tobacco output as measured by the quantity that is delivered to the auction floors is used to estimate supply elasticity. The objective is to determine if flue-cured tobacco supply is price elastic and whether price incentives alone will boost supply in the short -run. Time series data on flue cured tobacco output, prices, production costs, prices of major competing crops, the exchange rates and inflation are analysed to model the price...

Stresses such as cold and drought can impair plant yield and induce a highly complex array of responses. Sugarcane (Saccharum spp.) is cultivated in tropical and subtropical areas and is considered a cold-sensitive plant. We previously showed that cold stress induces the expression of several genes in in vitro sugarcane plantlets. Here we characterize one of those genes, SsNAC23, a member of the NAC family of plant-specific transcription factors, which are induced by low temperature and other stresses in several plant species. The expression of SsNAC23 was induced in sugarcane plants exposed to low temperatures (4ºC). With the aim of further understanding the regulatory network in response to stress, we used the yeast two-hybrid system to identify...

We evaluated the efficiency of two methods of drying SPs (M I and II) extracted from Halymenia sp Rhodophyceae in order to compare the yield, purification and anticoagulant activity. The total SPs (TSPs) were first extracted with papain in 100 mM sodium acetate (pH 5.0) containing cysteine and EDTA (5 mM). The TSPs obtained were dried in an oven (M I) or lyophilized (M II) and then examined by ion exchange chromatography (DEAE-cellulose) using the NaCl gradient technique. The fractions were analyzed by 0.5% agarose gel electrophoresis and the in vitro anticoagulant activity was evaluated by the activated partial thromboplastin time test using normal...

Autores: Dallago,Rogério Marcos; Valduga,Alice Teresa; Luccio,Marco Di; Benin,Silvane; Tres,Marcus Vinícius.
The adulteration of the product Ilex paraguariensis with other Ilex species is a mAjor problem for maté tea producers. In this work, three species of Ilex were evaluated for their volatile composition by headspace solid phase microextraction coupled to gas chromatography and mass spectrum detector (HS-SPME/GC-MS). The adulterating species I. dumnosa and I. theizans Mart. ex Reissek presented a different profile of volatile organic compounds when compared to I. paraguariensis. Aldehydes methyl-butanal, pentanal, hexanal, heptanal and nonanal were detected only in the adulterating species. This result suggests that such compounds are potential chemical markers for identification of adulteration and quality analysis of products based on Ilex paraguariensis.

Analytical Techniques for the Doppler Signature of Sea Surfaces in the Microwave Regime-I: Linear Surfaces
Provedor de dados: 5
Autores: Nouguier, Frederic; Guerin, Charles-antoine; Soriano, Gabriel.
This paper is the first in a series of two papers on the use of combined improved hydrodynamic and electromagnetic analytical models for the simulation of the ocean Doppler spectrum at microwave frequencies. Under a linear assumption for the sea surface, we derive statistical expression for the main Doppler characteristics according to asymptotic scattering models. We consider classical models such as the Kirchhoff approximation and the two-scale model, as well as the more recent weighted curvature approximation (WCA). We recover two salient features of Doppler signature in the microwave regime. First, the Doppler characteristics are very sensitive to polarization, with higher mean Doppler shift in horizontal polarization. This is correctly rendered by the...

Analytical Techniques for the Doppler Signature of Sea Surfaces in the Microwave Regime-II: Nonlinear Surfaces
Provedor de dados: 5
Autores: Nouguier, Frederic; Guerin, Charles-antoine; Soriano, Gabriel.
This paper extends the results of a previous work by combining hydrodynamic and electromagnetic analytical models for the simulation of the ocean Doppler spectrum at microwave frequencies. We consider weakly nonlinear sea surfaces after the choppy wave model and incorporate them in classical and unified scattering models, namely, the Kirchhoff and weighted curvature approximations. We show that statistical expressions can be obtained for the Doppler spectrum in a way similar to the case of linear surfaces. As expected, the nonlinear nature of the sea surface dramatically impacts the Doppler spectrum at moderate to large incidence angles, with a shift of the central frequency and a broadening of the spectrum. Monte Carlo comparisons are performed with the...

Analyzing Farmer Participation Intentions and Enrollment Rates for the Average Crop Revenue Election (ACRE) Program
Provedor de dados: 31
Autores: Mitchell,   Paul D.; Rejesus,   Roderick M.; Coble,   Keith H.; Knight,   Thomas O.
The 2008 Farm Bill created the Average Crop Revenue Election (ACRE) program as a new commodity support program. We analyze actual county-level ACRE enrollment rates and a mail survey of farmers just before the ACRE sign-up deadline in Mississippi, North Carolina, Texas and Wisconsin. As discussions begin regarding the next Farm Bill, an understanding of the factors affecting ACRE participation can provide guidance as program changes are discussed. Our empirical analysis of the survey suggest that initial farmer plans to switch to ACRE in 2009 were driven by producer perceptions of whether or not ACRE would pay more than existing programs and whether or not it would provide more risk protection. On the other hand, planning to stay with existing programs in...

Provedor de dados: 17
Autores: Jonathan D. Victor; Daniel J. Thengone; Mary M. Conte.
Because the space of signals that the visual system encounters is high-dimensional, investigations of visual processing and perception must utilize a sampling strategy.  One kind of approach begins with a class of models for input-output relations, and then chooses a stimulus ensemble such as white noise that enables efficient determination of model parameters.  A second kind of approach begins with the explicit recognition that it is important to understand the visual system in the context of the inputs under which it functions and evolves; this motivates the use of naturalistic stimulus ensembles.  Neither approach alone is sufficient: models built from ensembles such as white noise provide only a fair account of responses to natural scenes, and the...

Autores: Jolejole-Foreman,   Maria Christina; Mallory,   Mindy L.
In the Philippines, where rice is considered the most important food crop, attempts to influence rice prices have been prevalent. The government, through National Food Authority (NFA) has sought to establish stocks and control imports to stabilize prices since its establishment in 1972 to support farm gate prices and reduce retail price of rice. But data shows divergence in retail prices and farm prices since mid 1960s. In this paper, we use vector autoregression (VAR) to analyze the movement of Philippine rice margins with government stocks and weather supply shocks to able to determine government effectiveness in actual times of market stress. Comparing VARs across regions, we are able to identify the regions in which price margins are significantly...

Provedor de dados: 31
Autores: Yu,   Tun-Hsiang (Edward); Larson,   James A.; Gao,   Yuan; English,   Burton C.
It is generally believed that preprocessing procedure can reduce the transportation and storage costs of biomass feedstock for biofuel production by condensing the feedstock’s size. However, the capital costs of preprocessing facilities could be significant in the feedstock logistics system. Applying a GIS and mixed-integer mathematical programming model, this study evaluates the economic values of a preprocessing technology, stretch‐wrap baling, in the biomass feedstock supply chain for a potential commercial-scale switchgrass biorefinery in East Tennessee. Preliminary results suggest that the stretch-wrap baling equipment outperforms the conventional hay harvest methods in terms of total delivered costs. Although the densification process involves...

This paper describes the digestive system of Caiman crocodilus, Melanosuchus niger and Paleosuchus palpebrosus based on anatomical and topographical inferences. The study involves two digestive systems of C. crocodilus, one of M. niger and one of P. palpebrosus, already fixed in 10% formaldehyde, belonging to the collection of the Wild Animal Research Laboratory (LAPAS) of the Federal University of Uberlândia. The work begins with a description of the digestive system of the aforementioned crocodilians, followed by topographical associations, aided by photographs taken with a SONY® DSC-H20 camera, X-rays of the gastrointestinal tract and a photograph of the digestive system of C. crocodilus prior to formaldehyding, which also belong to the LAPAS...

In humans, the right coronary artery is dominant. However, we did not find any citations in the literature concerning anatomical indicators of dominance among dogs. We used 30 hearts from mongrels of both sexes, fixed in 10% formalin. The branches of the coronary arteries were dissected with special attention to the levels that were considered to be reference points. In 96.7%, the circumflex branch of the left coronary artery reached or went beyond the crux cordis. The subsinuosus interventricular artery, ended before reaching the apex in 21 cases, at the apex in five cases and after the apex in four cases. The paraconal interventricular artery, ended before reaching the apex in two cases, at the apex in 11 cases and after the apex in 17 cases. The region...

Anatomical Study of Position of the Rib Head for Placing Anterior Vertebral Body Screws in a Chinese Population
Provedor de dados: 77
Autores: Li,X. H; Xu,D. C; Li,Z. J; Wang,X.
Instrumentation of anterior vertebral body screws has become an important approach for treatment of unstable fracture or curvature of the spine, but little attention has been paid to the starting point of placing the screws and variability of the rib head position. We analyzed the variability of rib head position in a Chinese population in terms of the spinal canal and vertebral body using computed tomography (CT). Images from transverse CT scan of the T4-T12 vertebral bodies of 30 normal individuals were 3D reconstructed, and analyzed for measurement of parameters, which included: 1) distance between the left (or right) anterior border of the rib head and the posterior (or anterior) margin of the vertebral body [L(R )ARHP(A)VB], 2) left (or right)...

Provedor de dados: 77
Autores: Farooqui,M. M; Archana,Chandrapal; Prakash,Ajay.
A study was conducted on 70 embryo/ foetii of goats to observe the descent of testis. These foetii were grouped into I (0-30 days), II (31-60 days), III (61-90 days), IV (91-120days) and V (121 days up to term, having 14 embryos/ foetii in each group. The genital ridge was observed at 1.2cm CRL (23 day) on the ventromedial aspect of mesonephros. At 42nd day, the genital ridge developed into cylindrical structure, the testis, located in the middle of metanephros. The abdominal migration was completed upto 88th day. The testes were situated in the inguinal canal from 89th to 95th day. From 90th day onward, scrotal migration had been observed, however the testis did not reach the base of the scrotum up to term. During the descent of testis, a peritoneal fold...

The reproductive system of male Phrynops geoffroanus adults is macroscopically described and the variation in testicular biometry is evaluated. A pair of oval testes is connected by the efferent ductules to the epididymis, which continue as deferent ducts, which emerge in the penis. The volume of the gonads showed the highest averages during spring and summer months. GSI varied significantly throughout the year, with the highest averages observed in the months that correspond to the end of spring and the beginning of summer, when the reproduction of the species takes place, and the lowest averages were seen in winter, suggesting a cyclical testicular activity.

Autores: Moudry, Jan; Konvalina, Petr; Stehno, Zdenek; Capouchova, Ivana; Moudry, Jan (Jr.).
Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer...

Ancyrocephalidae (Monogenea) of Lake Tanganyika: I: Four new species of Cichlidogyrus from Ophthalmotilapia ventralis (Teleostei: Cichlidae), the first record of this parasite family in the basin
Provedor de dados: 103
Autores: Vanhove,Maarten P. M.; Volckaert,Filip A. M.; Pariselle,Antoine.
Examination of gill parasites from Ophthalmotilapia ventralis (Boulenger, 1898) in Lake Tanganyika (Africa) revealed the presence of four new species of Monogenea, all members of Cichlidogyrus Paperna, 1960 (Ancyrocephalidae). In view of the systematic importance of haptoral structure, the fish host shows a remarkable diversity of morphological groups. Cichlidogyrus vandekerkhovei sp. nov. and C. makasai sp. nov. are especially characterized by the unusual length of the dorsal transverse bar auricles, while C. sturmbaueri sp. nov. is distinguished by the unique shape of the accessory piece of its male copulatory organ. Importantly, C. centesimus sp. nov. displays a number of features new to the genus, namely a spirally coiled thickening at the end of the...

The aim of this study was to identify the times of anesthetic induction and recovery in slender seahorses (Hippocampus reidi) that were exposed to the essential oil of Lippia alba (EO), as well as the efficacy of EO as a stress-reducing agent in the transport of this species. Slender seahorses were placed in 1-L aquaria containing different concentrations of EO (0, 10, 20, 50, 150, 300 and 450 µL L-1), and after induction, fish were transferred to aquaria that were free of anesthetic to evaluate their recovery time. In an additional experiment, slender seahorses were transported in plastic bags with 15 µL L-1 of EO for 4 or 24 h. The increased concentration of EO proportionally decreased the time required for the induction of anesthesia. EO treatment (15...

O Cerrado é o segundo maior bioma brasileiro e é considerado um dos mais importantes hotspots de biodiversidade. Neste bioma foram registradas cerca de 150 espécies de anuros, das quais 30% são endêmicas. Entretanto, existem muitas áreas ainda não inventariadas, nas quais não se conhece quase nada sobre a diversidade de anuros. Assim, neste estudo apresentamos informações referentes a anurofauna do sudoeste do Estado de Goiás (Brasil Central), a qual vem sendo modificada principalmente pela agropecuária. Nesta região, 45 corpos d'água foram amostrados entre os meses de novembro/2007 a fevereiro/2008 e novembro/2008 a março/2009, localizados próximos a plantações de soja, cana-de-açúcar, pastagem e vegetação nativa.

Durch die zunehmende Beliebtheit ökologischer Lebensmittel bei Verbrauchern steigt das Angebot. Gleichzeitig nimmt jedoch auch der Wettbewerb zwischen ökologischen Erzeugern zu. Viele Produkte werden mittlerweile unter Bedingungen erzeugt, die zwar noch den Minimalanforderungen der EU-Öko-Verordnung an die Produktion entsprechen, in denen aber die ursprünglichen Werte der ökologischen Bewegung kaum noch beachtet werden. Diese ursprünglichen Werte bestehen z. B. in fairen Arbeitsbedingungen, in der Integration von benachteiligten Menschen, in besonders artgerechter Tierhaltung oder in der Erhaltung von bäuerlichen Traditionen und den regionaltypischen Landschaften.

Angiotensin II induces NF-κB, JNK and p38 MAPK activation in monocytic cells and increases matrix metalloproteinase-9 expression in a PKC- andRho kinase-dependent manner
Provedor de dados: 56
Autores: Yaghooti,H.; Firoozrai,M.; Fallah,S.; Khorramizadeh,M.R.
Angiotensin II (ANG II), the main effector of the renin-angiotensin system, is implicated in endothelial permeability, recruitment and activation of the immune cells, and also vascular remodeling through induction of inflammatory genes. Matrix metalloproteinases (MMPs) are considered to be important inflammatory factors. Elucidation of ANG II signaling pathways and of possible cross-talks between their components is essential for the development of efficient inhibitory medications. The current study investigates the inflammatory signaling pathways activated by ANG II in cultures of human monocytic U-937 cells, and the effects of specific pharmacological inhibitors of signaling intermediates on MMP-9 gene (MMP-9) expression and activity. MMP-9 expression...

Angiotensin-II-induced reactive oxygen species along the SFO-PVN-RVLM pathway: implications in neurogenic hypertension
Provedor de dados: 56
Autores: Braga,V.A.; Medeiros,I.A.; Ribeiro,T.P.; França-Silva,M.S.; Botelho-Ono,M.S.; Guimarães,D.D.
Neurogenic hypertension has been the subject of extensive research worldwide. This review is based on the premise that some forms of neurogenic hypertension are caused in part by the formation of angiotensin-II (Ang-II)-induced reactive oxygen species along the subfornical organ-paraventricular nucleus of the hypothalamus-rostral ventrolateral medulla pathway (SFO-PVN-RVLM pathway). We will discuss the recent contribution of our laboratory and others regarding the mechanisms by which neurons in the SFO (an important circumventricular organ) are activated by Ang-II, how the SFO communicates with two other important areas involved in sympathetic activity regulation (PVN and RVLM) and how Ang-II-induced reactive oxygen species participate along the...

Angolatitan adamastor, a new sauropod dinosaur and the first record from Angola
Provedor de dados: 42
Autores: Mateus,Octávio; Jacobs,Louis L.; Schulp,Anne S.; Polcyn,Michael J.; Tavares,Tatiana S.; Buta Neto,André; Morais,Maria Luísa; Antunes,Miguel T.
A forelimb of a new sauropod dinosaur (Angolatitan adamastor n. gen. et sp.) from the Late Turonian of Iembe (Bengo Province) represents the first dinosaur discovery in Angola, and is one of the few occurrences of sauropod dinosaurs in sub-Saharan Africa collected with good chronological controls. The marginal marine sediments yielding the specimen are reported to be late Turonian in age and, thus it represents a non-titanosaurian sauropod in sub-Saharan Africa at a time taken to be dominated by titanosaurian forms. Moreover, Angolatitan adamastor is the only basal Somphospondyli known in the Late Cretaceous which implies in the existence of relict forms in Africa.

Ángulo de Inclinación del Fémur en el Hombre y su Relación con la Coxa Vara y la Coxa Valga
Provedor de dados: 77
Autores: Gusmão,Luiz Carlos Buarque de; Sousa Rodrigues,Célio Fernando de; Martins,Josefa Sileda; Silva,Anselmo José da.
Los autores realizan mediciones en fémures aislados, realizando comparación de los datos obtenidos con los resultados encontrados en la literatura investigada, con el objeto de determinar de forma porcentual los valores limítrofes para clasificar la coxa como vara o valga. Fueron analizados 56 fémures de cadáveres adultos, siendo determinado el ángulo de inclinación del fémur, que fue medido a través de un Goniómetro. Utilizamos el patrón poblacional normal de 66% (o test Z) para determinar cuál es el intervalo donde se encuentra el alineamiento ideal. En las mediciones de los ángulos de inclinación de los 56 fémures, los valores se encontraban entre 117,67 grados y 136,67 grados. Utilizando el patrón poblacional normal de 66% (o test Z), verificamos que...

Continuous development is needed within the farm to reach the goal of good animal health and welfare in organic livestock farming. The very different conditions between countries call for models that are relevant for different farming types and can be integrated into local practice and be relevant for each type of farming context. This article reviews frameworks, principles and practices for animal health and welfare planning which are relevant for organic livestock farming. This review is based on preliminary analyses carried out within a European project (acronym ANIPLAN) with participants from seven countries. The process begins with gathering knowledge about the current status within a given herd as background for making decisions and planning future...

Animal manure for biogas production - what happens to the soil?
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen , Anders; Pommeresche, Reidun; Riley, Hugh.
Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured.

Animal welfare and eggs - cheap talk or money on the counter?
Provedor de dados: 21
Autores: Andersen, Laura Mørch.
Marginal willingness to pay for eggs carrying labels indicating different productions methods is estimated using Danish purchase data on individual level. Among other things the labels indicate environmental features and different levels of animal welfare for the hens that produce the eggs. Results show that consumers are generally willing to pay for labels indicating animal friendly production methods. It also appears that consumers living in urban areas are willing to pay more for animal welfare than people in rural areas and that people who perceive the level of animal welfare in organic eggs as higher are willing to pay more not only for organic eggs but also for other labels indicating increased animal welfare. The age of the main buyer has no...

ANN Based Virtual Classification Model for Discriminating Active and Inactive Withanolide E Analogs against  Human Breast Cancer Cell Line MCF-7
Provedor de dados: 17
Autores: Om Prakash; Feroz Khan; R.S. Sangwan.
Withanolides are a group of natural C-28 steroids built on an ergostane skeleton and classified into two major groups according to their structural skeleton: (a) compounds with a beta-oriented side chain and (b) compounds with an alpha-oriented side chain. Withanolide E represents one of the members of the latter group. Classification of active compounds on the basis of pharmacophore against specific cancer cell line poses a serious concern at the primary stage of virtual screening. To overcome this problem we have developed an artificial neural network based virtual screening model for discriminating active and non-active Withanolide-E-like derivatives or analogs against human breast cancer cell line MCF-7. In the present work, a 2D chemical descriptors...

Due to the complexity of the direct and indirect effects of the atmospheric aerosols on the air quality and atmospheric radiation balance, complementary methods are necessary to assess the aerosol optical properties. In this sense the backscatter lidar methods are critical in aerosol vertical distribution study. This work presents the annual cycle of aerosol backscatter coefficient (ABC) and aerosol mixed layer (AML) height over Neuch&amp;#xe2;tel, Switzerland (47.00 N; 6.950 E, 485 m asl). The study is performed by a ground based backscatter lidar operating at 532 nm wavelength as part of  EARLINET program of EU. Atmospheric layering for this study is based on a classification of lower atmosphere from 1 km to 2 km above sea level (asl) and from 2 km to 5...

Annual cycles of chlorophyll-a, non-algal suspended particulate matter, and turbidity observed from space and in-situ in coastal waters
Provedor de dados: 5
Autores: Gohin, Francis.
Sea surface temperature, chlorophyll, and turbidity are three variables of the coastal environment commonly measured by monitoring networks. The observation networks are often based on coastal stations, which do not provide a sufficient coverage to validate the model outputs or to be used in assimilation over the continental shelf. Conversely, the products derived from satellite reflectance generally show a decreasing quality shoreward, and an assessment of the limitation of these data is required. The annual cycle, mean, and percentile 90 of the chlorophyll concentration derived from MERIS/ESA and MODIS/NASA data processed with a dedicated algorithm have been compared to in-situ observations at twenty-six selected stations from the Mediterranean Sea to...

Four sets of measurements performed between 2005 and 2010 in the deep central Atlantic, the deep north-western Mediterranean Sea, and in the Arctic Ocean revealed strange anomalies in the performance of the Aanderaa optode 3830 sensors mounted on RCMI I current meters in low current regimes (current speeds &gt; 10 cm s(-1)). All oxygen datasets collected during these deployments showed significant drops of oxygen (50-100 mu mol) affecting the data stability of the optode sensors in low hydrodynamic conditions. High correlations between all acquired parameters (temperature, turbidity, speed and direction of currents) verified that no unusual event occurred in the mooring areas during the periods of acquisition, although natural events responsible for such...

Adaptation or acclimation to hypoxia occurs via the modulation of physiologically relevant genes, such as erythropoietin, transferrin, vascular endothelial growth factor, phosphofructokinase and lactate dehydrogenase A. In the present study, we have cloned, sequenced and examined the modulation of the LDH-A gene after an Amazonian fish species, Astronotus crassipinis (the Oscar), was exposed to hypoxia and anoxia. In earlier studies, we have discovered that adults of this species are extremely tolerant to hypoxia and anoxia, while the juveniles are less tolerant. Exposure of juveniles to acute hypoxia and anoxia resulted in increased LDH-A gene expression in skeletal and cardiac muscles. When exposed to graded hypoxia juveniles show decreased LDH-A...

Autores: Hörning, Bernhard; Vössing, Ulrich; Trei, Gerriet.
Auf Grundlage von Interviews mit 16 laufenden Projekten im deutschsprachigen Raum sowie der Literatur wird ein Überblick über Alternativen für die ökologische Geflügelzucht gegeben. Bisherige Feldprüfungen von Hybridherkünften ergaben keine optimale Herkunft. Eine Zucht spezieller Ökohybriden durch die Zuchtunternehmen erscheint mittelfristig unrealistisch. Die Leistungen von Rassehühnern können gesteigert werden durch Selektion innerhalb der Rasse oder durch Kreuzungen (mit anderen Rasse- oder mit Hybridhühnern). Im Beitrag werden jeweils entsprechende Beispiele vorgestellt.

Autores: Suguituru,Silvia Sayuri; Silva,Rogério Rosa; Souza,Débora Rodrigues de; Munhae,Catarina de Bortoli; Morini,Maria Santina de Castro.
Secondary forests and exotic tree plantations are expanding across tropical landscapes. However, our current understanding of the value of these human-dominated forest landscapes for invertebrate biodiversity conservation is still very poor. In this paper, we use the leaf-litter ant fauna to assess invertebrate diversity in one commercially managed Eucalyptus plantation (four years old), two abandoned plantations of different regeneration ages (16 and 31 years), and one neighboring secondary Atlantic Forest in Southeastern Brazil. There was a clear gradient in species richness from the secondary forest to the managed Eucalyptus plantation; richness and diversity peaked in secondary forest and in the older regenerating Eucalyptus plantation. Significantly...

Antagonistic effect of chitin-degrading microfungi on thick-shelled pig helminth eggs
Provedor de dados: 21
Autores: Katakam, KIran Kumar; Thapa, Sundar; Meyling, Nicholai V.; Dalsgaard, Anders; Roepstorff, Allan; Thamsborg, Stig Milan.
The rising demand for pigs produced in organic farming systems, which require access to outdoor areas and associated increased risk of gastrointestinal nematode infections, is creating growing interest in alternative control strategies. Also development of anthelminthic resistance due to extensive use of anthelmintics is a concern in intensive pig production. Use of chitin-degrading microfungi is one of the options. Extensive research has been conducted on biological control of plant pathogenic nematodes using such fungi, and some fungal species are commercially available for plant protection. In contrast, there are only limited laboratory studies conducted on eggs from nematodes which are animal parasites. The aim of present study is to investigate the...

Different solvents were evaluated for the extraction of jabuticaba anthocyanin pigments, identifying, quantifying and verifying the stability of the anthocyanins, as well as the conduction of three antioxidant activity assays and determination of the vitamin C levels. The maceration with ethanol acidified with HCl 1.5 mol L-1 (85:15) provides better pigment extraction and stability. The skin is anthocyanin rich, presenting 1.59 and 2.06 g 100 g-1 of dry matter in the Paulista and Sabará varieties, respectively. Cyanidin 3-glucoside is the majority pigment of the skins, followed by delphinidin 3-glucoside. The highest level of vitamin C was found in the skins and seeds of both varieties. It was verified that the skins, presented more antioxidant activity,...

2-acetyl physcion (2-acetyl-1,8-dihydroxy-6-methoxy-3-methyl-9,10-anthraquinone, 2), a rare anthraquinone, was isolated from Senna macranthera var. nervosa (Vogel) H.S. Irwin &amp;amp; Barneby (Fabaceae). The chemical structure was elucidated and all ¹H and 13C NMR chemical shifts were assigned by NMR one- (¹HNMR, {¹H}-13CNMR, and APT-13CNMR) and two (COSY, NOESY, HMQC and HMBC) dimensional of this natural compound. Furthermore, the minor anthraquinones chrysophanol (3), chrysophanol-8-methyl ether (4) and physcion (5) were characterized by GC-MS analysis. The occurrence of the anthraquinones 3-5 confirms that S. macranthera is a typical representative of the genus Senna.

In this paper the realized niche of the Snowy Plover (Charadrius alexandrinus), a primarily resident Florida shorebird, is described as a function of the scenopoetic and bionomic variables at the nest-, landscape-, and regional-scale. We identified some possible geomorphological controls that influence nest-site selection and survival using data collected along the Florida Gulf coast. In particular we focused on the effects of beach replenishment interventions on the Snowy Plover (SP), and on the migratory Piping Plover&amp;#x9;(PP)&amp;#x9;(Charadrius&amp;#x9;melodus )&amp;#x9;and&amp;#x9;Red&amp;#x9;Knot&amp;#x9;(RK)&amp;#x9;(Calidris&amp;#x9;canutus ).&amp;#x9;Additionally, we investigated the potential differences between the SP breeding and wintering...

Our objective was to determine whether anthropometric measurements of the midarm (MA) could identify subjects with whole body fat-free mass (FFM) depletion. Fifty-five patients (31% females; age: 64.6 ± 9.3 years) with mild/very severe chronic obstructive pulmonary disease (COPD), 18 smokers without COPD (39% females; age: 49.0 ± 7.3 years) and 23 never smoked controls (57% females; age: 48.2 ± 9.6 years) were evaluated. Spirometry, muscle strength and MA circumference were measured. MA muscle area was estimated by anthropometry and MA cross-sectional area by computerized tomography (CT) scan. Bioelectrical impedance was used as the reference method for FFM. MA circumference and MA muscle area correlated with FFM and biceps and triceps strength. Receiver...

To contribute to the development of antibacterial products from propolis produced by native Brazilian bees, twenty-nine samples of propolis collected from hives in the state of Minas Gerais, Brazil, were screened for in vitro activity against Aeromonas hydrophila, Bacillus subtilis, Pseudomonas aeruginosa, and Staphylococcus aureus. Among the samples from native Brazilian bees, only that from Frieseomelitta varia (Lepeletier, 1836) inhibited in vitro bacterial growth. Consequently, this propolis underwent fractionation by chromatographic methods monitored through Agar-diffusion assays with these bacteria, which resulted in the isolation and identification of 3,5-diprenyl-4-hydroxycinnamic acid (artepillin C), which showed MIC of 62.5 and 250 µg/mL against...

Autores: Rezvanpanah,Shila; Rezaei,Karamatollah; Golmakani,Mohammad-Taghi; Razavi,Seyyed Hadi.
Antibacterial properties and chemical characterization of the essential oils from summer savory (Satureja hortensis) extracted by microwave-assisted hydrodistillation (MAHD) were compared with those of the essential oils extracted using the traditional hydrodistillation (HD) method. While MAHD at 660 W required half as much time as HD needed, similar antibacterial efficacies were found from the essential oils obtained by the two extraction methods on two food pathogens (Staphylococcus aureus, a gram positive bacterium, and Escherchia coli, a gram negative bacterium). Also, as it was the case with the essential oils extracted by HD, that of MAHD indicated greater influence on S. aureus than on E. coli. The compositions of the extracted essential oils were...

Antidepressant suppression of REM and spindle sleep impairs hippocampus-dependent learning and memory but fosters striatal-dependent strategies
Provedor de dados: 17
Autores: Alain Watts; Howard Gritton; Jamie Sweigart; Gina Poe.
REM sleep enhances hippocampus-dependent associative memory but has little impact on striatal-dependent procedural learning. Antidepressant medications like desipramine (DMI) inhibit rapid-eye-movement (REM) sleep but it is little understood how antidepressant treatments affect learning. We found that DMI strongly suppressed REM sleep in rats for several hours and impaired reconsolidation of a familiar maze and consolidation of moved baited positions (reversal learning) in a sleep-dependent fashion. Unexpectedly, DMI also reduced the spindle-rich transition-to-REM sleep state (TR) and spatial memory changes were more related to TR than to REM sleep. Working memory was unaffected, but overnight reference memory was significantly impaired and subjects...

Autores: Lavkush Dwivedi; Mansi Shrivastava.
Human immunodeficiency virus (HIV), with about 30 million deaths and double infections (in developing countries), is an open challenge today for global scientists. Developing safe and effective measurements against it has become the prime need of hour. Though, putting it at health priority, various efforts like chemotherapy, vaccines and others are attempted globally over last decade. Consequently, highly active antiretroviral therapy was introduced but fails to completely block the viral replication due to drug resistance and various other severe side effects. The antigenic variability and lack of appropriate experimental models is the major obstacle in the development of an ever effective treatment against HIV. However, to overcome the present hurdles...

Visceral leishmaniasis (VL), also known as kala-azar, is an important public health problem. If not treated, virtually all clinically symptomatic patients die within months. The diagnosis is based on the Montenegro skin test (MST) and anti-Leishmania titers. Nevertheless, the time required for cured individuals living in a leishmaniasis-endemic area to present a positive skin test and negative anti-Leishmania serology is known. To determine the cellular and humoral immune response profile in relation to different times post-VL cure, a cross-sectional study was conducted on subjects from a kala-azar endemic area in Paço do Lumiar, MA, Brazil, on the basis of 1995-2005 notifications reported by the National Health Foundation/Regional Coordination of...

The DT dichloromethane extract exhibited a strong anti-proliferative activity on MCF-7 and LNCaP cells, and was further fractionated and sub-fractionated by RP-HPLC. High resolution mass spectrometry and spectrophotometric analysis unequivocally identified violaxanthin as the most antiproliferative molecule present in DT DCM extract. Violaxanthin purified from DT induced MCF-7 dose- dependent growth inhibition in continuous and discontinuous treatments, at...

Provedor de dados: 74
Autores: Borges,Kleiton Silva; Brassesco,María Sol; Scrideli,Carlos Alberto; Soares,Ademilson Espencer Egea; Tone,Luiz Gonzaga.
Propolis is a resin formed by a complex chemical composition of substances that bees collect from plants. Since ancient times, propolis has been used in folk medicine, due to its biological properties, that include antimicrobial, anti-inflammatory, antitumoral and immunomodulatory activities. Glioblastoma is the most common human brain tumor. Despite the improvements in GBM standard treatment, patients' prognosis is still very poor. The aim of this work was to evaluate in vitro the Tubi-bee propolis effects on human glioblastoma (U251 and U343) and fibroblast (MRC-5) cell lines. Proliferation, clonogenic capacity and apoptosis were analyzed after treatment with 1 mg/mL and 2 mg/mL propolis concentrations for different time periods. Additionally,...

Autores: Silva,Ara; Morais,SM; Marques,MMM; Lima,DM; Santos,SCC; Almeida,RR; Vieira,IGP; Guedes,MIF.
In recent years, the search for natural plant products to fight viral diseases has been increasing. In this work, two Spondias species, namely S. mombin and S. tuberosa, found in Ceará state (Brazil), and their main phenolic components were evaluated against dengue virus. In vitro antiviral tests were performed against type-2 dengue virus by the MTT method and standard cytopathic effect reduction assay in C6/36 cells. Cytotoxicity was also evaluated by MTT. The presence of phenolic compounds quercetin, rutin, and ellagic acid in plant extracts was characterized by HPLC analysis. Both Spondias species extracts and components were nontoxic to the cells whereas rutin and quercetin displayed relevant antiviral activity with IC50 of 362.68 µg/mL and 500 µg/mL,...

Water-soluble sulfated polysaccharides isolated from two red algae Sphaerococcus coronopifolius (Gigartinales, Sphaerococcaceae) and Boergeseniella thuyoides (Ceramiales, Rhodomelaceae) collected on the coast of Morocco inhibited in vitro replication of the Human Immunodeficiency Virus (HIV) at 12.5 mu g/mL. In addition, polysaccharides were capable of inhibiting the in vitro replication of Herpes simplex virus type 1 (HSV-1) on Vero cells values of EC(50) of 4.1 and 17.2 mu g/mL, respectively. The adsorption step of HSV-1 to the host cell seems to be the specific target for polysaccharide action. While for HIV-1, these results suggest a direct inhibitory effect on HIV-1 replication by controlling the appearance of the new generations of virus and...

Effects of a synthetic Aluminium-Magnesium Silicate (AMS) on Avian Influenza Virus (AIV) were tested. Equal amounts of H5N1 AIV samples and of AMS were mixed, left one hour, at room temperature before centrifuging. The supernatants were remeasured and tested for viral titre, for Mean Death Time (MDT) and Embryo Mortality Rate (EMR) of chicken eggs. Volumes of the viral samples reduced at rate of 23.4 &amp;#xb1; 5.48 %. Viral titres reduced significantly (P from HA, 73 &amp;#xb1; 32.72 to 1.4 &amp;#xb1;0.43). Also, mortality of infected embryos reduced from 100 % to 65% while MDT of those that died, increased significantly (P = 0.001) from 76 &amp;#xb1; 4.38 to 130 &amp;#xb1;17.27 hours.

Estamos en un periodo de búsqueda de soberanía suramericana, pero también de modelos de transformación de nuestras sociedades, en el marco de reglas democráticas, donde los gobiernos tienen periodos y se renuevan por medio de procesos electorales, todo esto después de  muchísimos años de gobiernos arrodillados al norte.  Creo que la doctrina de la nueva izquierda todavía no está clara, hablar de socialismo del siglo XXI es una aspiración, pero no veo un cuerpo doctrinario suficientemente homogéneo.  Yo le hablé alguna vez al Presidente Hugo Chaves, y le dije que no me parece bien depender tanto de una persona, de un liderazgo individual, que hay que crear un partido que sea capaz de mantenerse en el poder, para eso son los partidos, para que las ideas...

Anuran amphibians' diversity in a northwestern area of the Brazilian Pantanal
Provedor de dados: 49
Autores: Pansonato,André; Mott,Tamí; Strüssmann,Christine.
In the Pantanal, the largest continuous floodplain in the world, the diversity and distribution of anuran amphibians vary in and across distinct subregions and distinct habitats occurring along inundation gradients. Permanent and natural aquatic habitats are relatively scarce in the Pantanal, and occurrence of temporary aquatic habitats varies seasonally, depending on rains. We here present results of evaluations of anuran's species richness and abundance in a seasonally flooded area in the northwestern section of the Pantanal (Fazenda Baía de Pedra, Cáceres municipality, state of Mato Grosso, Brazil), comparing values obtained in 10 plots systematically distributed over 5 km² with those obtained in additional aquatic plots in the study area.

Autores: Siqueira,Carla C; Vrcibradic,Davor; Dorigo,Thiago A; Rocha,Carlos F. D.
The anurofauna inhabiting higher montane Atlantic forest areas in southeastern Brazil, which often attain heights of more than 2000 m, is still insufficiently known. In this study, we present data on anuran species composition and abundances in two high-altitude (i.e. &gt; 1000 m) sites within the Parque Estadual dos Três Picos (PETP), in the state of Rio de Janeiro. Field surveys were done at altitudes between 1100 and 1900 m above sea level. We recorded 35 species during our study, adding 22 records to the set of anuran species previously known to occur within the PETP. The stability of the species accumulation curve, as well as the richness estimations, showed that the sampling methodology employed and the total sampling effort were appropriate to...

Provedor de dados: 49
Autores: Sabbag,Ariadne Fares; Zina,Juliana.
We surveyed anuran amphibians in a riparian forest fragment of the Córrego do Espraiado, located at the Universidade Federal de São Carlos, Municipality of São Carlos, state of São Paulo, southeastern Brazil. During March 2009 and February 2010 we did weekly surveys in which we recorded 13 anuran species. The species showed a seasonal reproductive activity. In addition, we found a positive correlation between the number of reproductively active species and photoperiod. We also found that the studied community was more similar to those of transitional areas between the Atlantic Forest and Cerrado than those of the nearby Cerrado fragments.

Anurofauna da floresta de restinga do Parque Estadual da Ilha do Cardoso, Sudeste do Brasil: composição de espécies e uso de sítios reprodutivos
Provedor de dados: 49
Autores: Vilela,Vívian Maria de Faria Nasser; Brassaloti,Ricardo Augusto; Bertoluci,Jaime.
O Parque Estadual da Ilha do Cardoso é uma área de grande importância para a conservação, pois abriga diferentes ecossistemas costeiros, como manguezais, dunas, restingas e mata atlântica de encosta, que, historicamente, estiveram sob forte pressão antrópica. A identificação duvidosa e a descoberta de novas espécies da anurofauna em ambientes costeiros, evidencia a escassez de estudos nessas regiões. Inventariamos a anurofauna da floresta de restinga do Parque Estadual da Ilha do Cardoso entre outubro de 2005 e outubro de 2007, por meio de 25 viagens mensais de dois dias de duração. Foram utilizados dois métodos: procura visual ativa em uma parcela permanente de 10 ha e procura visual e auditiva em nove sítios de reprodução. A anurofauna da área de estudo...

Autores: Provete,Diogo Borges; Garey,Michel Varajão; Silva,Fernando Rodrigues da; Rossa-Feres,Denise de Cerqueira.
A correta identificação de espécies normalmente é um obstáculo para estudos de conservação, manejo e licenciamento ambiental. Atualmente 37 espécies de cinco famílias de anfíbios anuros são registradas na área que abrange integralmente as Unidades de Gerenciamento dos Recursos Hídricos (UGRHIs) do Turvo-Grande e São José dos Dourados e parte das UGHRIs do Baixo Pardo, Baixo Tietê e Tietê-Batalha. Embora esta fauna venha sendo objeto de estudos quase ininterruptos desde a metade da década de 1960, nenhuma chave de identificação que incluísse todas as espécies reconhecidas na região estava disponível. Embora desenvolvida para uma anurofauna regional, esta chave tem ampla aplicação porque as espécies encontradas na área de abrangência do estudo são associadas...

Apigenin inhibits cell migration through MAPK pathways in human bladder smooth muscle cells
Provedor de dados: 47
Autores: Qingxin,Liu; Xianggui,Chen; Guolin,Yang; Xuewen,Min; Maoxian,Deng.
Apigenin, a nonmutagenic flavonoid, has been shown to possess free radical scavenging activities, anticarcinogenic properties, antioxidant and anti-inflammatory effects. Recently, apigenin was reported to cause gastric relaxation in murine. To assess possible effects of apigenin on migration of bladder smooth muscle (SM) cell, we isolated SM cells from peri-cancer tissue of human bladder and established a cell model that was capable to overexpress transiently MEKK1 (MEK kinase 1). Results showed that overexpression of active human MEKK1 by adenoviruses infection induced migration of human bladder smooth muscle (hBSM) cells and phosphorylation of MAPKs, ERK, JNK and p38, which are the downstream molecules of MEKK1. Then, hBSM cell overexpressing MEKK1 were...

Autores: Rodrigues,Alessandro; Araujo,João Paulo Campos de; Girardi,Eduardo Augusto; Scarpare,Fabio Vale; Scarpare Filho,João Alexio.
A videira 'Itália' (Vitis vinifera L.) é a cultivar de uva fina para mesa mais consumida no Brasil. A qualidade dos cachos é uma característica fundamental, sendo o tamanho das bagas o componente mais valorizado pelos consumidores. Uma das alternativas para incrementar a qualidade das bagas é o uso de biorreguladores. Avaliaram-se, em três ciclos de produção, os efeitos de doses de ácido giberélico (AG3) isolado e associado com forchlorfenuron (CPPU), na qualidade dos cachos de uva Itália produzida em Porto Feliz-SP. A aplicação dos biorreguladores foi realizada aos 25 dias após o florescimento, em delineamento experimental inteiramente casualizado, em fatorial 4X4 (zero, 10; 20 e 30 mg L-1 AG3 X zero, 5; 10 e 15 mg L-1 CPPU), com oito repetições para o...

Autores: Lima,Antonio Luís dos Santos; Lima,Keila dos Santos Cople; Gody,Ronoel Luiz de Oliveira; Araújo,Leandro Moreira; Pacheco,Sidney.
O tucumã (Astrocaryum vulgare Mart.) é um fruto nativo da Amazônia, de ocorrência principal no estado do Pará, mas também encontrado nos estados do nordeste e do centro-oeste brasileiro. O tucumã é considerado como uma excelente fonte de carotenóides com maior concentração em β-caroteno, precursor da vitamina A, e além dos carotenóides, também é importante fonte de vitamina B2 (riboflavina). Por este motivo, o presente trabalho objetivou analisar os efeitos da irradiação gama sobre o valor nutricional do tucumã. Os frutos de tucumã foram irradiados com as doses de 0,5, 1,0 e 2,0 kGy num irradiador com fonte de césio 137. Foram determinados os teores de carotenóides totais por espectrofotometria. As análises de α e β-caroteno, tiamina, riboflavina foram...

Autores: Oliveira,Marla Ibrahim Uehbe de; Funch,Ligia Silveira; Santos,Francisco de Assis Ribeiro dos; Landrum,Leslie Roger.
Para avaliar a utilidade de caracteres morfoanatômicos na identificação de materiais botânicos de Campomanesia Ruiz &amp;amp; Pavón, especialmente aqueles estéreis, o padrão de nervação foliar e a configuração do arco vascular no pecíolo de 15 táxons presentes no estado da Bahia foram analisados. O padrão de nervação secundário camptódromo-broquidódromo mostrou-se uniforme entre os táxons, assim como a nervação última marginal em arcos e a nervação terciária do tipo reticulada ortogonal. Diferenças foram observadas quando considerados a presença de nervuras intersecundárias e o tipo de aréolas na lâmina foliar, e a configuração do arco vascular e a natureza da bainha perivascular no pecíolo, podendo estes caracteres ser utilizados para fi ns taxonômicos.

Provedor de dados: 70
Autores: Nunes,Matheus A. G.; Kunz,Airton; Steinmetz,Ricardo L. R.; Paniz,José N. G.
Este trabalho avaliou o efeito da diluição do dejeto de suíno com o efluente tratado a 50% (v/v), com vistas a aumentar a desnitrificação via fornecimento de carbono ao processo. Considerando-se a diluição estudada, a concentração média de N-NO3- na mistura foi de 47,9 + 14,5 mg L-1, e a DQO da mistura, na faixa de 17.543 + 675 mg L-1, resultando numa relação DQO/N-NO3- de 366, extremamente favorável à ocorrência da atividade desnitrificante no tanque de homogeneização da mistura. A concentração de N-NO3- foi reduzida biologicamente a 0,5 mg L-1 (cerca de 1% da concentração inicial). O procedimento testado promoveu, ainda, uma melhora na etapa de separação sólido-líquido, empregando coagulantes naturais, onde foi observado um consumo de tanino inferior ao...

Aplicação de modelos múltiplos na determinação de níveis de prejuízo para a interação Solanum americanum e tomate de indústria
Provedor de dados: 87
Autores: Portugal,J.M; Moreira,I.
Este estudo apresenta um conceito unificador, que conjuga as teorias de densidade crítica e período crítico. Hipotetiza-se que não existe um valor fixo para a densidade crítica e para o período crítico, mas que os seus valores são interdependentes. A demonstração dessa hipótese é fundamentada em estudos de interferência entre Solanum americanum e o tomateiro. Aos resultados da produção de cinco ensaios, aplicaram-se modelos múltiplos de regressão, tendo como variáveis independentes a densidade e o número de dias de convivência entre a infestante e a cultura. A aplicação do Nível de Tolerância (NT) à representação gráfica num plano das equações estimadas a partir de modelos múltiplos permite responder à questão: Quanto tempo pode permanecer uma determinada...

Autores: Dutra Filho,João de Andrade; Melo,Luiz José Oliveira Tavares de; Resende,Luciane Vilela; Anunciação Filho,Clodoaldo José da; Bastos,Gerson Quirino.
Estudos sobre divergência genética são importantes na identificação de genitores potenciais para a obtenção de novos indivíduos com maior efeito heterótico. Em cana-de-açúcar esses estudos assumem fundamental importância, pois com o passar do tempo as variedades comerciais devem ser substituídas de suas áreas de cultivo, devido a sérios declínios agronômicos e industriais ocasionados pela degenerescência varietal. Sendo assim, o objetivo deste trabalho foi avaliar a divergência genética em progênies de cana-de-açúcar, através de técnicas multivariadas, com base em oito caracteres agroindustriais. O trabalho foi conduzido na área agrícola da Usina Santa Tereza, município de Goiana (PE), durante o ano agrícola 2007/2008. Foi utilizado o delineamento...

Aplicação do conceito do índice padronizado de precipitação à série decendial da diferença entre precipitação pluvial e evapotranspiração potencial
Provedor de dados: 53
Autores: Blain,Gabriel Constantino.
O monitoramento probabilístico e padronizado da variabilidade temporal dos totais de chuva, proposto pelo modelo do Índice Padronizado de Precipitação (SPI), tem sido utilizado por programas estaduais e federais na detecção de regiões com severos déficits de precipitação pluvial. Contudo, algumas questões conceituais, inerentes a um índice que utiliza apenas a precipitação pluvial como variável independente, tendem a distanciar esse índice dos interesses agrícolas. O objetivo do trabalho foi verificar a possibilidade de aplicação desse conceito de monitoramento probabilístico/padronizado, adotado/proposto pelo SPI, às séries decendiais da diferença entre precipitação pluvial e evapotranspiração potencial (P-ETP).

Apesar de ser uma área ainda pouco explorada, é crescente o número de estudos dessas espécies nativas, dentre eles, os que abrangem as técnicas de cultura de tecidos. Isso se deve uma vez que essa ferramenta biotecnológica permite a propagação de espécies com dificuldade de germinação, minimiza o problema de sementes recalcitrantes, promove a produção de mudas em larga escala, complementa bancos de germoplasma e facilita as trocas de materiais genéticos. Dessa maneira, esta revisão visa a sumarizar o histórico e panorama atual das aplicações da cultura de tecidos em fruteiras do cerrado, proporcionando...

As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding. The values estimated for the Nervión river in the city of Amurrio (Álava) indicate that the average expected damage will increase in 15 per cent as a consequence of CC (from €56,097 to €64,451). For an extreme episode the total loss could increase to €20 million. The second framework is oriented towards the valuation of the...

Autores: Alberti,Aline; Vieira,Renato Giovanetti; Drilleau,Jean Françoise; Wosiacki,Gilvan; Nogueira,Alessandro.
The aim of this work was to evaluate the nitrogen content in different varieties of apple musts and to study the effect of different nitrogen concentrations in apple wine fermentation. The average total nitrogen content in 51 different apples juices was 155.81 mg/L, with 86.28 % of the values above 100 mg/L. The apple must with 59.0, 122.0 and 163.0 mg/L of total nitrogen content showed the maximum population of 2.05x 10(7); 4.42 x 10(7) and 8.66 x 10(7) cell/mL, respectively. Therefore, the maximum fermentation rates were dependent on the initial nitrogen level, corresponding to 1.4, 5.1 and 9.2 g/L.day, respectively. The nitrogen content in the apple musts was an important factor of growth and fermentation velocity.

Application of a bioenergetic growth model to larvae of the pearl oyster Pinctada margaritifera L.
Provedor de dados: 5
Autores: Thomas, Yoann; Garen, Pierre; Pouvreau, Stephane.
We applied, for the first time, a dynamic energy budget (DEB) growth model to the larval phase in the pearl oyster Pinctada margaritifera var. cumingii (Linnaeus, 1758) to evaluate the impact of spatio-temporal variation in the atoll lagoon environment on its capacity for development. The specific parameters of the model, which represent ingestion, temperature effect and the relationship between length and biovolume of the larvae, were determined from experiments or taken from the literature. The interpretation of the values of these parameters allowed us to identify the underlying adaptive character trait: P. margaritifera larvae have a good capacity to exploit low food concentrations and a narrow range of thermal tolerance restricted to hydrobiological...

Applications and Interviews. A Structural Analysis of Two-Sided Simultaneous Search
Provedor de dados: 31
Autores: Wolthoff,   Ronald P.
Much of the job search literature assumes bilateral meetings between workers and firms. This ignores the frictions that arise when meetings are actually multilateral. I analyze the magnitude of these frictions by presenting an equilibrium job search model with an endogenous number of contacts. Workers contact firms by applying to vacancies, whereas firms contact applicants by interviewing them. Sending applications and interviewing applicants are costly activities but increase the probability to match. In equilibrium, contract dispersion arises and workers spread their applications over the different contract types. Estimation of the model on the Employment Opportunities Pilot Projects data set provides values for the cost of an application, the cost of an...

Issues on energy have recently dominated the economic decisions of several states across the U.S. economy and states in the southeastern region of U.S. are no exception. Almost all the states in the southeast import virtually all of their fuel resources from the Gulf Coast representing an annual financial diversion of several billions of dollars some of which could be used to develop domestic, alternative energy resources. The focus of this study was to determine the potential substitution between renewable energy and conventional energy forms in the southeast of U.S. We developed a system of factor share equations using translog cost function. The system of equations was estimated using a pooled iterative Non-linear Seemingly Unrelated Regression (SUR)...

We present a simple subtraction procedure of GDDSC as a modification of the original DSC and GDRDA methods. Genetically Directed Differential Subtraction Chain (GDDSC) is a process by which highly related genomes are compared in order to isolate tags carrying the polymorphisms. &amp;#xd;&amp;#xa;To detect specific DNA fragment (tag), we can then monitor offspring plants for efficient molecular breeding. The GDDSC protocol was applied to isolation of new sex related clones from cucumber plants (_Cucumis_ _sativus_ L.) and new tissue culture response clones from rye (_Secale_ _cereale_ L.). The newly identified tags, obtained by GDDSC represent pools of candidate genes and other sequences, which could serve as potential markers for requested traits.

This study presents a thorough discussion of the efficiency and effectiveness improvement from optimization models (Binary Linear Programming and Goal Programming), as applied to the Department of Defense’s Readiness and Environmental Protection Initiative. The OM models can yield 21% and 19.1% higher benefit scores respectively, spending $13,013,473 and $31,463,473 less total acquisition costs. To achieve the same level of conservation benefits for the current rank based approach, the REPI would spend additional $20.1 million and approximate 50% of the budget. A counterpart of OM- the cost-effective analysis is observed to be inefficient when the problem becomes complex. In a real world of political environment of the conservation programs, we suggest a...

Applying the Payment Card Approach to Estimate the WTP for Green Food in China
Provedor de dados: 31
Autores: Tian,   Xu; Yu,   Xiaohua; Holst,   Rainer.
This paper uses a payment card approach to reveal consumers‟ willingness to pay for green food in China. We first present a brief introduction of the payment card approach and introduce several methods to estimate the WTP with payment cards, which we subsequently use to estimate WTP values regarding green vegetables, green meat and green eggs in China. Our results indicate that consumers in big cities are willing to pay a higher premium for green food and that WTP values are relatively higher for more expensive food than for cheaper food. In addition, the ratios of premium to price range mainly between 25% and 50% and WTP values obtained from interval midpoint approach are relatively higher than those calculated by other approaches.

The Common Monitoring and Evaluation Framework (CMEF) provides a single framework for monitoring and evaluation of all EU Rural Development Programmes (RDP) in the current programming period (2007-2013). It provides continuity from previous periods and constitutes a significant simplification as regards assessment of results and impacts, while at the same time offering greater flexibility to Member States. The European Evaluation Network for Rural Development has published a Working Paper on Approaches for assessing the impacts of the Rural Development Programmes in the context of multiple intervening factors. The aim of the Working Paper is to inspire and to encourage programme evaluators, not to restrict or constrain them. From a methodological...

Aquaporinas: de canais de água a transportadores multifuncionais em plantas
Provedor de dados: 88
Autores: Gaspar,Marília.
Da identificação funcional da primeira aquaporina de plantas, em 1993, aos dias de hoje, uma grande quantidade de informações sobre a estrutura, a localização e a função dos diferentes membros desta família multigênica de proteínas de membrana foi disponibilizada pela comunidade científica. Inicialmente consideradas como "simples canais de água", as aquaporinas se mostraram capazes de transportar gases e pequenos solutos neutros, como glicerol, uréia e silício, revolucionando o conceito de transporte transmembrana. Devido à redundância dos genes de aquaporinas e à sua distribuição em todos os órgãos e tecidos vegetais, essas proteínas têm sido consideradas essenciais na manutenção de funções vitais, como absorção de água e nutrientes em raízes, germinação...

Der Arbeitszeitbedarf für Legehennen in Bodenhaltung unterscheidet sich kaum von dem in der Volierenhaltung: Gesamtarbeitszeitbedarf und Verteilung auf die einzelnen Arbeitsgänge sind annähernd gleich. Der größte Arbeitszeitbedarf liegt mit einem Anteil von 53 % bei der Produktgewinnung. Die Betriebsführung macht einen Anteil von 17% am Gesamtarbeitszeitbedarf aus. Bei beiden Arbeiten handelt es sich um tägliche, meist mit hohem manuellem Aufwand verbundene Tätigkeiten. Produktgewinnung, Betriebsführung, Fütterung und Auslaufbewirtschaftung summieren sich auf 92 % des Arbeitszeitbedarfs. Einfluss auf den Arbeitszeitbedarf haben vor allem die Bestandsgröße und der Anteil an manuellen Tätigkeiten.

The combination of bacteria and arbuscular mycorrhizal fungi (AMF) would be ideal for nutrient biodvnamics in soils and protection from soil-borne plant pathogens (SBPP). During the process of plant colonization AMF interact with bacteria where spores cytoplasm and hvphae provide specific niches for certain populations of bacteria. The clarification of the relationship AMF-bacteria has great potential for sustainable agriculture. The currently research aimed to isolate and characterize bacteria. Which we have designated most probable endobacteria (MPE) from an AMF spore. Three bacterial strains were taken from about 500 spores by using a 200 &amp;#xb5;m diameter hvpodermic needle.

Sie bilden ein engmaschiges Pilzfadengeflecht im Boden und geben lebensnotwendige Nährstoffe aus dem Boden an die Pflanzen weiter und schützen diese gegen Stress und Trockenheit.  Sie reduzieren Nährstoffverluste aus dem Boden und können durch Lebendverbauung Erosion vermindern und somit die Stabilität on Ökosystemen erhöhen. AM-Pilze scheinen als Bioindikatoren besonders geeignet zu sein, da diese Pilzgruppe mit bisher bekannten 230 Arten überschaubar klein ist und sowohl häufige als auch seltene Arten enthält.

Arbustos de la estepa patagónica: ¿adaptados a tolerar la sequía o el pastoreo?
Provedor de dados: 67
Autores: Golluscio,Rodolfo A; Cavagnaro,Fernando P; Valenta,Magalí D.
En zonas áridas, la sequía es la principal fuerza selectiva que actúa sobre las poblaciones vegetales. Sin embargo, las plantas de zonas áridas, aun las de sitios con corta historia evolutiva de pastoreo, serían tolerantes al pastoreo porque los caracteres que les proveen tolerancia a la sequía también les proveen tolerancia a la herbivoría. La historia evolutiva de pastoreo de las estepas del centro y noroeste de la Patagonia ha sido considerada corta y sus arbustos dominantes, muchas veces espinosos, han sido considerados adaptados a tolerar la sequía. En este trabajo presentamos evidencias experimentales que cuestionan ese modelo conceptual. (1) Los tres arbustos más conspicuos de la comunidad dominante en el sudoeste de Chubut (Mulinum spinosum,...

Archaeal Populations in Hypersaline Sediments Underlying Orange Microbial Mats in the Napoli Mud Volcano
Provedor de dados: 5
Autores: Lazar, Cassandre Sara; L'Haridon, Stephane; Pignet, Patricia; Toffin, Laurent.
Microbial mats in marine cold seeps are known to be associated with ascending sulfide- and methane-rich fluids. Hence, they could be visible indicators of anaerobic oxidation of methane (AOM) and methane cycling processes in underlying sediments. The Napoli mud volcano is situated in the Olimpi Area that lies on saline deposits; from there, brine fluids migrate upward to the seafloor. Sediments associated with a brine pool and microbial orange mats of the Napoli mud volcano were recovered during the Medeco cruise. Based on analysis of RNA-derived sequences, the "active" archaeal community was composed of many uncultured lineages, such as rice cluster V or marine benthic group D. Function methyl coenzyme M reductase (mcrA) genes were affiliated with the...

Arcobacter butzleri: first isolation report from chicken carcasses in costa rica
Provedor de dados: 58
Autores: Arias,Maria Laura; Cid,Adriana; Fernandéz,Heriberto.
Arcobacter butzleri isolation from chicken carcasses in Costa Rica is reported for the first time. The isolated strains (P and R) were presumptively identified by their phenotypic characteristics. Definitive identification was made using a multiplex PCR assay for the simultaneous detection and identification of Arcobacter butzleri, Arcobacter cryaerophilus and Arcobacter skirrowii. These first isolations indicate the necessity of further investigation about the prevalence, distribution, ecology and interactions with human beings of this and other Arcobacter species.

Are Agricultural Options Overpriced?
Provedor de dados: 31
Autores: Urcola,   Hernan A.; Irwin,   Scott H.
As agricultural options markets grow, perceptions of overpricing persist among market participants. This study tests the efficiency of corn, soybean, and wheat options by computing trading returns. Several call and put option strategies yield significant profits, but returns are influenced by movements in the futures price, and straddle trading does not lead to significant returns. The combined analysis of put, call, and straddle returns indicates that significant returns can be attributed to drifts in the underlying futures, and that the corn, soybean, and wheat options markets are efficient.

Are Competitors' Free Trade Agreements Putting U.S. Agricultural Exporters at a Disadvantage?
Provedor de dados: 31
Autores: Wainio,   John; Dyck,   John H.; Gehlhar,   Mark J.; Vollrath,   Thomas L.
The growing number of free trade agreements among U.S. competitors has prompted questions about whether U.S. agricultural exporters may lose a share of the global market. ERS research shows that the recently created ASEAN-China and ASEANAustralia/ New Zealand free trade agreements are likely to have modest adverse impacts on U.S. agricultural exports. The Mercosur-Colombia free trade agreement has reduced U.S. agricultural exports to Colombia; U.S. grain sellers face increasingly stiff competition due to preferential tariffs granted to Mercosur exporters.

Autores: Janssen, Meike; Hamm, Ulrich.
Since July 2010, prepacked organic food produced in the EU must be labelled with the new mandatory EU logo for organic food. However, there is a long tradition of voluntary organic certification logos in most European countries. In this paper we analyse the willingness-to pay (WTP) of European consumers for products with different voluntary organic certification logos to make recommendations for actors in the organic sector. Data was collected by means of choice experiments with 1,997 consumers of organic food in five EU countries, based on which a number of random parameter logit models were estimated. According to our results, there were great differences between the tested logos regarding the price premium that consumers were willing to pay compared to...

An analysis of published data on oceanic seabirds diets, show the predominance of muscular cephalopods with superficial distribution in the oceanic layers, but also important are the gelatinous and ammoniacal species restrict to layers below 300 m from the surface. In principle, it could be not expected that deep-sea cephalopods are common prey for seabirds like several authors have been concluded. It is proposed in this study that an indirect source, important and easily attainable, have been appeared with the beginning of tuna longline operations. The habit to feed upon viscera of the fishes captured by tuna longliners, that discard the gut contents to the water, may explain the probable equivocal conclusions that deep dwelling cephalopods are natural...

Autores: Kristensen, Hanne L.; Kidmose, Ulla; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Differences in nutrient availability and methods of pest management may affect crop growth and product quality. The question is whether conventional and organic cropping systems, which differ clearly in strategies for nutrient and pest management, influence the harvest and sensory quality of the products? With the aim to elucidate this question, lettuce and onion were grown in a conventional and three organic cropping systems with increasing levels of nutrient re-cycling and use of intercrops for natural pest management in the period of 2007-2009. The conventional and first organic system relied fully on external inputs in the form of NPK or liquid manure for nutrient management, respectively. In the second organic system, low external inputs of liquid...

Are larger and/or more symmetrical Drosophila melanogaster (Diptera, Drosophilidae) males more successful in matings in nature?
Provedor de dados: 92
Autores: Pavković-Lu&amp;#269;ić,Sofija; Kekić,Vladimir.
Are larger and/or more symmetrical Drosophila melanogaster (Diptera, Drosophilidae) males more successful in matings in nature? Sexual selection in Drosophila melanogaster, related to body size and fluctuating asymmetry in wing length and number of sex comb teeth in males, was tested in natural conditions. Males collected in copula were significantly larger than those collected as a single, while no difference in mean number of sex comb teeth between copulating and single males was observed. On the other hand, single males had greater asymmetry both for wing length and number of sex comb teeth than their mating counterparts. It looks like that symmetry of these bilateral traits also may play a role in sexual selection in this dipteran species in nature.

Are levels of digestive enzyme activity related to the natural diet in passerine birds?
Provedor de dados: 48
Autores: Ramírez-Otárola,Natalia; Sabat,Pablo.
Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence of a correlation between the morphology and physiology of the intestinal tract and chemical features of the natural diet. However, studies correlating the activity of digestive enzymes and the feeding habits at an evolutionary scale are scarce. We investigated the effect of dietary habits on the digestive physiological characteristics of eight species of passerine birds from Central Chile. The Order Passeriformes is a speciose group with a broad dietary spectrum that includes omnivorous, granivorous and insectivorous species. We...

Are Local Corn Prices Affected by the Location of Ethanol Biorefineries?
Provedor de dados: 31
Autores: Katchova,   Ani L.
This study examines whether the local competition for corn to produce ethanol has lead to significantly higher prices for farmers located close to ethanol biorefineries. If any, such price premiums for spatial closeness would be in addition to the general level of corn price changes experienced by farmers throughout the U.S. The difference-in-differences estimation method is used to account for both time and spatial differences in order to measure the interaction of time and spatial effects. Using the USDA’s ARMS data, the results show that while prices in real terms have changed over time, farmers located close to ethanol biorefineries have not received significantly higher prices than farmers living farther away from biorefineries. These findings...

Men&amp;#x27;s drive for group control and power appears to be an evolutionary inheritance, but it is females, and not males, who developed better abilities for prolonged control and group interaction while males have higher rates of ADHD and autism. This contradictory allocation of sex-related abilities describes the observable behavior, but not the internal meaning attribution leading to the motivation of men and women. Our study in Canada, China and Russia shows that men estimate power- and status-related concepts in significantly more positive terms than women, but give significantly more negative estimations to work-related and reality-related concepts. Men also have a consistent tendency to estimate concepts as less real (even...

Are Organic Farmers Really Better Off Than Conventional Farmers?

We employed the propensity score matching and estimated the causal effect of being certified organic crop producers on farm household income and its various components in the United States. Contrary to the standard assumption in economic analysis, certified organic farmers do not earn significantly higher household income than conventional farmers. Certified organic crop producers earn higher revenue but they incur higher production expenses. In particular, certified organic producers spend significantly more on labor expenses, insurance payments, and marketing charges than conventional farmers. The results suggest that early adopters of organic farmers have done so for non pecuniary reasons and the lack of economic incentives can be an important barrier...

This paper uses a non-market valuation study to elicit consumers’ preferences for a marine restoration programme in the Black Sea aiming to reduce the level of public health risk from bathing and improve water quality and the overall level of marine biodiversity. In this context, we administer a stated choice experiment in coastal settlements in Ukraine and Turkey and employ two tax revenue reallocation schemes as payment vehicles. One proposes the financing of the marine restoration programme by the reduction of the public budget for renewable energy and the second by the reduction of the public budget on training for civil servants. We examine the stated preferences and the subsequently derived economic value estimates in the two treatments with the aim...

Downy mildew caused by the obligate biotrophic oomycete Plasmopara viticola is one of the most important and devastating diseases of grapevine. Copper-based fungicides are used to control the disease in organic vineyards. However, since 2006, copper use has been limited by an European Commission regulation. In this study conducted from 2004 to 2007, we tested materials that might replace copper in organic viticulture, under controlled greenhouse and field conditions at two locations in Europe (northern Italy and Switzerland). We tested 112 different treatments, including biocontrol agents, materials of animal origin, homeopathic preparations, inorganic materials, microbial extracts, natural derivatives, plant extracts, physical methods and synthetic...

Are there Carbon Savings from US Biofuel Policies? Accounting for Leakage in Land and Fuel Markets
Provedor de dados: 31
Autores: Bento,   Antonio M.; Klotz,   Richard; Landry,   Joel R.
This paper applies the insights of the carbon leakage literature to study the emissions consequences of biofuel policies. We develop a simple analytic framework to decompose the intended emissions impacts of biofuel policy from four sources of carbon leakage: domestic fuel markets, domestic land markets, world land markets and world crude oil markets. A numerical simulation model illustrates the magnitude of each source of leakage for combinations of two current US biofuel policies: the Volumetric Ethanol Excise Tax Credit (VEETC) and the Renewable Fuel Standard (RFS). In the presence of both land and fuel market leakage, current US biofuel policies are unlikely to reduce greenhouse gases. Four of the five policy scenarios we consider lead to increases in...

An increase in the frequency and intensity of environmental crises associated with accelerating human-induced global change is of substantial concern to policy makers. The potential impacts, especially on the poor, are exacerbated in an increasingly connected world that enables the emergence of crises that are coupled in time and space. We discuss two factors that can interact to contribute to such an increased concatenation of crises: (1) the increasing strength of global vs. local drivers of change, so that changes become increasingly synchronized; and (2) unprecedented potential for the propagation of crises, and an enhanced risk of management interventions in one region becoming drivers elsewhere, because of increased connectivity. We discuss the...

Area response in wheat production: The Australian wheat-sheep zone
Provedor de dados: 31
Autores: Culas,   Richard J.
This paper investigates the key decision parameters of farmers related to the allocation of land between wheat production and pasture for sheep (wool) production. Wheat area supply response, is estimated across the Australian wheat-sheep zone using data for the period 1991 to 2004. Statistical results reveal that wheat growers in Western Australia are more price responsive than growers in the eastern states. Area adjustment is not significantly different between the regions. Rainfall has a positive influence on wheat production while time-related exogenous factors such as technical progress seemed to have little influence on the wheat yield over this period.

Autores: Tlapa Almonte, Margarita.
En el estado de Puebla, México, se decretaron siete Áreas Naturales Protegidas (ANP) periurbanas, una con categoría de Parque Estatal y seis Reservas Ecológicas. Su establecimiento fue una respuesta a problemas de conservación de recursos naturales y a la necesidad de establecer una área de regulación del crecimiento urbano de la ciudad de Puebla. Sin embargo, no se conoce que tan funcionales han sido estas ANP. La presente investigación tuvo como objetivo identificar y analizar los factores que inciden en el funcionamiento de las siete ANP periurbanas del estado de Puebla.

Provedor de dados: 14
Autores: PEDREIRA, B. da C. C. G.; FIDALGO, E. C. C.; UZEDA, M. C.; COSTA, M. D. A. da.
A região da bacia dos rios Guapi-Macacu, situada no contexto ambiental da Mata Atlântica do Rio de Janeiro, concentra expressivo percentual da produção agrícola fluminense e provê abastecimento de água para quase 2 milhões de pessoas. Os recursos naturais da região são protegidos pela presença de um conjunto de unidades de conservação de uso sustentável e de proteção integral em seu entorno. Entretanto, o processo desordenado de ocupação do solo associado às práticas de manejo e cultivo inadequadas empregadas na região concorre para a sua degradação ambiental, comprometendo a sustentabilidade de sua produção. Sob esse contexto, este estudo objetivou identificar áreas prioritárias para recuperação na região da bacia hidrográfica do rio Guapi-Macacu em...

Armadillo : la otra cara de la moneda del ITT (Opinión)

Mientras todo el mundo está entretenido con el tema del ITT en una esquina del Parque Nacional Yasuní, incluyendo los ambientalistas más radicales, en el otro extremo del mapa, en una zona al norte, colindante al Parque Nacional Yasuní, en un pequeño campo llamado marginal, se consagra la operación exterminio. Y se la consagra violando todas las normas constitucionales, acuerdos internacionales y mínimos derechos de un pueblo al que insistentemente, e intencionalmente, se lo oculta. ¿Por qué decimos esto? Pues porque mientras nos llenamos la boca con eso de que queremos proteger a los pueblos “sin contacto”, en un lugar donde se ha comprobado su presencia parece que no estamos dispuestos a proteger nada ni a nadie. Esa zona se llama Armadillo. Y está fuera...

Aromas potentiality of tuna cooking juice concentrated by nanofiltration
Provedor de dados: 5
Autores: Walha, Khaled; Ben Amar, Raja; Masse, Anthony; Bourseau, Patrick; Cardinal, Mireille; Cornet, Josiane; Prost, Carole; Jaouen, Pascal.
Tuna cooking juices contain high organic load preventing the rejection in the environment without treatment. But the effluents present an interesting fishy odour and it is worth recovering aroma compounds. In this work, two industrial tuna cooking juices were concentrated by nanofiltration. Nanofiltration performance was discussed in terms of permeation fluxes, organic matter retention and impact on the aromatic properties of juices. NF sharply decreases the global intensity of juices and modifies their aromatic equilibrium. However, the main characteristics and the marine nature of juices were kept. A pre-treatment by microfiltration (MF) induces a marked increase in permeation fluxes during NF concentration while it slightly affects the aromatic...

Arrhenius&amp;#x27; theory of partial dissociation and hydration of electrolytes in solutions replaces existing activity concepts
Provedor de dados: 17
Autores: Raji Heyrovska.
The author shows that Arrhenius&amp;#x27;s theory of partial electrolytic dissociation was immaturely displaced about eight decades ago by the empirical concept of ionic activities and the assumption of complete dissociation of electrolytes at all concentrations. The latter brought the theory of electrolytes over the next decades into a complicated state without any physical significance. Therefore, the author started a systematic investigation of the available data and could completely restore the original theory of partial dissociation. Now solution properties can be easily understood and quantitatively explained in terms of absolute concentrations and volumes of ions and ion pairs and hydration.

We analyzed variations in stable isotope ratios (15N/14N and 13C/12C) of fertilizers, plants, prey and generalist predators in organic and conventional farming systems in a long-term agricultural experiment [DOK trial (bioDynamic, bioOrganic, Konventionell)]. Two basal resources with pronounced differences in carbon isotope signatures, wheat litter (C3 plant) and maize litter (C4 plant), were used to uncover differences in food web properties between the two farming systems (conventional versus organic).  2 Predators incorporated significantly higher proportions of carbon from wheat...

Forensic Entomology research has been concentrated in only a few localities of the "Cerrado" vegetation, the Brazilian Savannah. The present study had, as its objective, an examination of the diversity of arthropod fauna associated with the carcasses of Sus scrofa (Linnaeus) in this biome. The study was conducted during the dry and humid periods in two Cerrado vegetation profiles of the State of Minas Gerais. The decaying process was slower and greater quantities of arthropods were collected during the dry period. Insects represented 99% of 161,116 arthropods collected. The majority of these were Diptera (80.2%) and Coleoptera (8.8%). The entomofauna belong to 85 families and at least 212 species. Diptera were represented by 31 families and at least 132...

Artificial nests as an alternative to studies of arboreal small mammal populations: a five-year study in the Atlantic Forest, Brazil
Provedor de dados: 103
Autores: Loretto,Diogo; Vieira,Marcus Vinícius.
Despite the great diversity of Brazilian Atlantic forest small mammals, natural history of most species is unknown due to their cryptic and nocturnal habits, but also due to the inadequacy of methods to capture some species, especially those of arboreal habits. A new technique, based on the use of artificial nests (AN) to record arboreal marsupials, is presented. Artificial nests were combined with traditional live traps to study the population ecology of four didelphid marsupial species. After 62 months of monitoring, 119 individuals were recorded 243 times (total success = 5.2%). Only 26 individuals (22%) were recorded by both AN and live trap methods, and two of the four species were never captured by live traps, only by AN. Live traps alone would have...

Autores: 姜, 興起; 野田, 英雄; Kyo, Koki; Noda, Hideo.
多くの経済時系列データは，トレンド，季節変動，循環変動などの複数の変動成分 を含むと考えられる．本稿では，循環変動がAR モデルで表現される場合の変動成分 (AR 成分) に着目する．モデル構築においてそうした経済時系列の構造が適切に反映さ れていなければ，分析の結果，誤った結論を導く危険性がある．本稿の目的は，AR 成 分を導入した季節調整モデルのパラメータを推定するための新たなアプローチを開発し， 従来のアプローチとの比較で我々の新規提案法の優位性を示すことである．新規提案の 逐次推定法と従来の同時最適化による同時推定法のアルゴリズムのパフォーマンスをシ ミュレーションによって検討した結果，逐次推定法のアルゴリズムの方がきわめて短い 計算時間で済み，かつ安定的な推定結果を導くことが確認された． In general, economic time series data consist of trend, seasonal variation, cyclical variation, and others. This paper focuses on a cyclical variation represented by an autoregressive (AR) model, that is, AR component. If such structure of economic time series is not appropriately reflected in modeling, then analytical results might be misleading. This paper aims to develop a new method for estimating...

O principal objectivo deste artigo é conhecer as atitudes dos agricultores face à produção agrícola, ao apoio político e ao projecto de rega de Alqueva numa micro-região mediterrânica do Sul de Portugal, no contexto da Política Agrícola Comum (PAC) de 2003 e do Health-Check. Simultaneamente, pretende-se conhecer as intenções comportamentais destes agricultores frente à inovação tecnológica e ao futuro regadio público neste contexto político. Os resultados destacam que a grande maioria destes agricultores constituem um grupo relativamente homogéneo face às suas atitudes. Este cluster mantém uma mentalidade muito produtivista, um forte desejo de manter um foco agrícola, rejeitando veementemente noções de liberalização política. Apesar de possuírem elevada...

AS condições climáticas e sua influência na sarna da macieira.
Provedor de dados: 14
Autores: ALVES, S. A. M.; MONTEIRO, J. E. B. de A.
Algumas variáveis climáticas dos últimos três anos são apresentadas na forma de gráficos nas figuras abaixo. O motivo de se pensar nos últimos três anos é devido à existência de dados desse período na rede de estações do INMET e, principalmente, a grande diferença da safra atual em relação às anteriores. A baixa incidência da sarna nesta primavera é algo que chama a atenção. A tendência natural é de aumento nos problemas fitossanitários ao longo dos anos em uma determinada quadra ou pomar. Isso acontece porque os fungos possuem estratégias de sobrevivência e a freqüência dos isolados mais adaptados aumenta. Na safra passada, a severidade da sarna foi bastante alta e a expectativa para essa safra era que o inóculo estivesse num nível elevado já no início da...

Ascertaining the Impact of the 2000 USDA Dietary Guidelines for Americans on the Intake of Calories, Caffeine, Calcium, and Vitamin C from At-Home Consumption of Nonalcoholic Beverages
Provedor de dados: 31
Autores: Dharmasena,   Senarath; Capps,   Oral, Jr.; Clauson,   Annette L.
Obesity is one of the most pressing and widely emphasized health problems in America today. Beverage choices made by households have impacts on determining the intake of calories, calcium, caffeine, and vitamin C. Using data from the Nielsen Homescan Panel over the period 1998–2003, and a two-way random-effects Fuller-Battese error components procedure, we estimate econometric models to examine economic and demographic factors affecting per-capita daily intake of calories, calcium, caffeine, and vitamin C derived from the consumption of nonalcoholic beverages. Our study demonstrates the effectiveness of the USDA 2000 Dietary Guidelines in reducing caloric and nutrient intake associated with nonalcoholic beverages.

Asian Rice Policies and WTO Commitments on Domestic Support Under Existing and Proposed Doha Round Provisions
Provedor de dados: 31
Autores: Yang,   Min-Hsien; Blandford,   David.
We examine current rice policies in four major Asian countries (China, Japan, Korea, and Taiwan), their relationship to current WTO disciplines, and to those proposed under the Doha negotiations. WTO disciplines have prompted some changes in rice policies, but disciplines of domestic support are unlikely to impose serious constraints in the future. Using the example of Taiwan, we examine how existing support policies could be changed to reduce domestic distortions and satisfy WTO commitments. Changing from existing amber box payments to those that would likely qualify for inclusion under the blue or green boxes could allow greater market orientation in Taiwan’s rice market, while satisfying food security and farm income support objectives.

Asimetría Fluctuante: Una herramienta morfo-funcional para Medir Estabilidad del Desarrollo
Provedor de dados: 77
Autores: Benítez,Hugo A; Parra,Luis E.
La capacidad de un organismo para producir un fenotipo ideal, pese a las perturbaciones encontradas durante su desarrollo, es el mecanismo causal de la estabilidad del desarrollo (ED). Esta capacidad es utilizada para evaluar variedad de tipos de estrés y la capacidad genotípica de corregirlos. La herramienta de medición más utilizada para estimar la ED es la asimetría fluctuante (AF), siendo esta una medida de las pequeñas desviaciones al azar que ocurren entre el lado izquierdo y derecho de rasgos bilateralmente simétricos. El estudio de AF, por su simplicidad de manejo y rapidez en la obtención de resultados, se ha convertido en un foco de interés para la biología, y durante los últimos años el aumento en artículos publicados usando AF para evaluar...

Asociación espuria en el modelo de regresión logística con series de tiempo
Provedor de dados: 115
Autores: Ramírez-Valverde,Gustavo; Islas-Monroy,J. Carlos; Ramírez-Valverde,Benito.
La asociación espuria en el modelo de regresión lineal ocurre cuando la variable independiente contribuye a explicar de manera importante la variabilidad de la variable respuesta de acuerdo con la prueba de hipótesis sobre el parámetro de la variable independiente, a pesar de que ambas variables no tienen ninguna relación. En modelos con variable respuesta categórica la presencia de asociación espuria no está reportado en la literatura. Por tanto, en este estudio se muestra empíricamente la existencia del fenómeno en regresión logística cuando los datos son generados por diferentes procesos de serie de tiempo que involucran series no estacionarias. El análisis de los resultados obtenidos indica que este fenómeno ocurre cuando el mecanismo generador de la...

A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats.

Autores: Saki,AA; Rahmati,MMH; Eskandarlou,A; Zamani,P; Hosseini Siyar,SA.
In this study, the effects of the inclusion of different vitamin C levels in the diet on bone mineral density (BMD) and eggshell quality was determined. Four experimental diets with four levels of vitamin C (0, 250, 500 and 750 mg/kg) were used. During the experiment, environmental temperature and humidity were 19±1°C and 55±5% respectively. Correlation coefficients of BMD index and shell characteristics with production parameters were also determined. Egg weight, egg mass, hen-day egg production and eggshell quality were not significantly influenced by vitamin C levels. BMD was not affected by vitamin C utilization. A positive correlation was observed between BMD and egg weight and hen-day egg production. A significant positive correlation between...

Assessing community values for reducing agricultural emissions to improve water quality and protect coral health in the Great Barrier Reef
Provedor de dados: 31
Autores: Rolfe,   John; Windle,   Jill.
Key policy issues relating to protection of the Great Barrier Reef from pollutants generated by agriculture are to identify when measures to improve water quality generate benefits to society that outweigh the costs of reducing pollutants. The research reported in this paper makes a key contribution in several key ways. First, it uses the improved science understanding about the links between management changes and reef health to bring together the analysis of costs and benefits of marginal changes, helping to demonstrate the appropriate way of addressing policy questions relating to reef protection. Second, it uses the scientific relationships to frame a choice experiment to value the benefits of improved reef health, and links improvements explicitly to...

Assessing Consumer Willingness to Pay for Value-Added Blueberry Products Using a Payment Card Survey
Provedor de dados: 31
Autores: Hu,   Wuyang; Woods,   Timothy A.; Bastin,   Sandra; Cox,   Linda J.; You,   Wen.
This study offers insights on consumer acceptance and willingness to pay for three value-added blueberry products. A modified payment card approach was used. The analytical framework adopted allows the researcher to attach straightforward economic interpretation to the estimated impacts of willingness to pay factors. Results show consumer socio-economic characteristics are important determinants but play different roles depending on the products. Information on health benefits may also be important. However, it is found that outside information or consumer self-stated awareness of blueberries’ health benefits have different impacts. These impacts may function as substitutes rather than complements to each other.

Assessing Domestic Demand for Organic and ‘Locally Grown' Produce on An ‘Organic Island': Dominica's Dilemma
Provedor de dados: 31
Autores: Boys,   Kathryn A.; Willis,   David B.; George,   Seraphine; Hammig,   Michael D.
The economy of Dominica faces a unique set of challenges.  As with many other Caribbean nations, Dominica has historically been dependent upon agriculture.  Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008).  Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008).  While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination.  Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

Assessing El Nino Southern Oscillation variability during the past millennium
Provedor de dados: 5
Autores: Khider, D.; Stott, L. D.; Emile-geay, J.; Thunell, R.; Hammond, D. E.
We present a reconstruction of El Nino Southern Oscillation (ENSO) variability spanning the Medieval Climate Anomaly (MCA, A. D. 800-1300) and the Little Ice Age (LIA, A. D. 1500-1850). Changes in ENSO are estimated by comparing the spread and symmetry of delta O-18 values of individual specimens of the thermocline-dwelling planktonic foraminifer Pulleniatina obliquiloculata extracted from discrete time horizons of a sediment core collected in the Sulawesi Sea, at the edge of the western tropical Pacific warm pool. The spread of individual delta O-18 values is interpreted to be a measure of the strength of both phases of ENSO while the symmetry of the delta O-18 distributions is used to evaluate the relative strength/ frequency of El Ni o and La Ni a...

The paper develops a mathematical programming model for assessing the impact of Environmental Policy instruments on French winegrowing farm’s adoption of pesticides-saving technologies. We model choices with regards to investment in precision farming and plant protection practices, in a multi-periodic framework with sequential decision, integrating uncertainty on fungal disease pressure and imperfect information on equipment performance. We focus on recursive models maximizing a Utility function. These models are applied on a representative sample of 534 winegrowers from the French Farm Accountancy Data Network (FADN). As expected, both ecotaxes and green subsidies make precision farming equipment more profitable, but the investment rate remains however...

The aim of this study was to estimate the values to protect the health of the Great Barrier Reef (GBR) at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from nearly 1,000 km to over 4,000 km from Brisbane. The results suggest that the average WTP across Australian households is $21.68 per household per annum for five years. There was some evidence of distance decay in values.

Assessing Participation in the Milk Income Loss Contract Program and its Impact on Milk Production
Provedor de dados: 31
Autores: D'Antoni,   Jeremy M.; Mishra,   Ashok K.
The MILC program, a counter-cyclical income support program, was designed to provide price support to dairy farmers. Since the inception of the MILC program it has been argued that the program is inefficient and rewards inefficiency by keeping high cost, small dairy farms in business. Large dairy producers have expressed concerns that the MILC payments have negatively affected their farming income. Using farm-level, ARMS data from 2005, this study investigated the factors that affect farmer’s decision to participate in MILC program and if participation in MILC has an impact on milk production. The results show that participation in MILC program is positively correlated with farmer’s educational attainment, organic certification subsidy, milk price,...

Autores: Szakács,Gabor Gyula Julius; Cerri,Carlos Clemente; Herpin,Uwe; Bernoux,Martial.
The growing demand of world food and energy supply increases the threat of global warming due to higher greenhouse gas emissions by agricultural activity. Therefore, it is widely admitted that agriculture must establish a new paradigm in terms of environmental sustainability that incorporate techniques for mitigation of greenhouse gas emissions. This article addresses to the scientific demand to estimate in a fast and inexpensive manner current and potential soil organic carbon (SOC) stocks in degraded pastures, using remote sensing techniques. Four pastures on sandy soils under Brazilian Cerrado vegetation in São Paulo state were chosen due to their SOC sequestration potential, which was characterized for the soil depth 0-50 cm. Subsequently, a linear...

Assessing structural change in agriculture with a parametric Markov chain model. Illustrative applications to EU-15 and the USA
Provedor de dados: 31
Autores: Piet,   Laurent.
The Markov chain model (MCM) has become a popular tool in the agricultural economics literature to explain the past evolution of and simulate the future developments in the number and size distribution of farms. In this paper, I show that the way MCMs have been implemented by agricultural economists so far suffers from the fact that transition probabilities are estimated as almost independent variables (up to adding-up to unity constraints). The alternative parametric MCM I propose addresses the deriving issues since (i) it is parsimonious in terms of parameters; (ii) it can be estimated with simple econometric techniques; (iii) it reveals detailed information on the structural change processes at hand. Applying it to experimentally controlled data with...

Autores: Targetti,   Stefano; Viaggi,   Davide; Cuming,   David; Sarthou,   J.P.; Choisis,   J.P.
Organic and low-input farming practices are considered keystones for the conservation of biodiversity in semi-natural systems. Accordingly, attention to the assessment of the benefits stemming from these activities is increasing in order to provide a solid base for the adoption of agro-environmental incentives and to support their monitoring and evaluation. The evaluation of the positive effects of organic and low-input farming activities on biodiversity is limited mainly by: the difficulty in proposing simple and widely-applicable indicators of biodiversity, and the substantial lack of data concerning the costs of measuring biodiversity - an essential element for a cost-effectiveness analysis. Moreover, the limited scientific literature available is based...

Autores: Bartolini,   Fabio; Latruffe,   Laure; Viaggi,   Davide.
Literature on innovation adoption mechanism has emphasised the positive effect of Single Farm Payments (SFP) and Rural Development Payments on adoption of new technologies. In this context, the expected process of CAP reforming after 2013 is likely to strengthen the role of innovation in the European Union (EU). The objective of this paper is to identify the determinants of the adoption of future innovation, in particular in connection to past innovation, and to assess the role of agricultural policy in the promotion of innovation adoption. The analysis is applied to two regions (Centre and Midi-Pyrénées) in France. Two separate Count models are developed in order to explain famers’ stated intention concerning different intensities of innovation adoption...

Provedor de dados: 31
Autores: Cai,   Ruohong; Bergstrom,   John C.; Mullen,   Jeffrey D.; Wetzstein,   Michael E.
In this paper, a dynamic optimization model was developed to simulate how farm-level realized price and profitability respond to yield change which was induced by climate change. Producers' acreage response was included in the dynamic model considering crop rotation effect. In the crop rotation model, a modified Bellman equation was used to dynamically optimize the net present value of farm profit for a five-year interval. This simulation process was repeated through the year 2050. Then yield, price, and acreage response were compiled to generate realized profit. Results generally indicated that reduction in crop yields due to climate change results in reduced farm profitability for most of the states studied. Predicted climate change is more likely to...

The country is facing one of the biggest challenges since its independence – the process of the EU accession. Taking into consideration that „forecasting important economic events is source of power“ (Howitt, 2005), the aim of this paper is to develop a model in order to assess the impact of the EU membership on the Macedonian agriculture. The model is recursive, dynamic, multi-product partial equilibrium model for the meat, dairy and cereals sector in the Republic of Macedonia. It follows the AGMEMOD principles, hence comprising the local features of the Macedonian agriculture. The baseline scenario shows a positive growth of the pig meat, lamb meat and cow milk sectors. On the other hand, in the EU scenarios the most positive effect is expected in the...

Concerns about nutrient loads into our waters have focused attention on poultry litter applications.  Like many states with a large poultry industry, Georgia recently designed a subsidy program to facilitate the transportation of poultry litter out of vulnerable watersheds. This paper uses a transportation model to examine the necessity of a poultry litter subsidy to achieve water protection goals in Georgia. We also demonstrate the relationship between diesel and synthetic fertilizer prices and the value of poultry litter.

Assessing the Opportunity Cost of Growing a Bioenergy Crop in California: a PMP Approach
Provedor de dados: 31
Autores: Yi,   Fujin; Merel,   Pierre R.; Lee,   Juhwan; Six,   Johan.
A significant increase in demand for fuel ethanol in California should be expected if all gasoline sold in the state were to be blended with 10% ethanol, as envisaged in the State Alternative Fuels Plan. This paper assesses the potential of California agriculture to supply biofuel feedstock in the form of switchgrass. We construct a fully calibrated, multi-region, multi-input and multi-output model of agricultural supply for California’s Central Valley based on the principles of Positive Mathematical Programming. We exploit the biogeochemical model DAYCENT to estimate production functions for switchgrass in each agricultural region. We then predict the extent and location of potential switchgrass production in the Central Valley. Our results suggest that...

Assessing the potential for beneficial diversification in rain-fed agricultural enterprises
Provedor de dados: 31
Autores: Kandulu,   John.
Climate change and climate variability induce uncertainty in yields, and thus threaten long term economic viability of rain-fed agricultural enterprises. Enterprise mix diversification is the most common, and is widely regarded as the most effective, strategy for mitigating multiple sources of farm business risk. We assess the potential for enterprise mix diversification in mitigating climate induced variability in long term net returns from rain-fed agriculture. We build on APSIM modelling and apply Monte Carlo simulation, probability theory, and finance techniques, to assess the potential for enterprise mix diversification to mitigate climate-induced variability in long term economic returns from rain-fed agriculture. We consider four alternative farm...

Assessing the public goods provided by organic agriculture: lessons learned from practice
Provedor de dados: 21
Autores: Smith, Laurence; Padel, Susanne; Pearce, Bruce; Lampkin, Nic; Gerrard, Catherine L; Woodward, Lawrence; Fowler, Sue; Measures, Mark.
The role of farms as providers of public goods has long been recognised, and measuring performance in this area is of increasing interest to policy makers, in light of the approaching Common Agricultural Policy reform. The Organic Research Centre has been working on this topic in recent years, through the development of sustainability assessment tools. The latest outcome from this process is a ‘Public Goods’ assessment tool, developed through a Natural England funded project which aimed to evaluate the benefits accruing from organic management and entering into an Organic Entry Level Stewardship (OELS) agreement. This paper describes the development of the Public Goods (PG) tool, and what has been learned in the process.

Assessing the Technical and Allocative Efficiency of Marketing Decisions by U.S. Organic Producers
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
We develop measures of technical and allocative efficiency of producers in marketing certified organic products. A stochastic output distance frontier and the associated revenue share equations are estimated using comprehensive U.S. data on certified organic producers. Farm-level measures of technical efficiency are calculated and factors which enhance performance are identified. Factors that systematically influence allocative efficiency are assessed. The revenue mix of organic producers is systematically inefficient as both male and female producers rely too heavily on revenue from organic markets relative to conventional outlets.

Assessment of agricultural land fund in the Czech Republic, importance and future
Provedor de dados: 31
Autores: Voltr,   Vaclav.
Assessment of land depends on the production function of soil and additional connections given by environmental requirements, by the evaluation of public goods or by the requirements for formation a fair tax policy and even by the interests of landowners. Analysis of coherences during the soil appraisal shows a relatively strong dependence on the development of year-by-year yields and cost including subsidy policy, which is strongly reflected in the grasslands. Development of subsidies does not basically influence a long- term return and costs ratio for the production on arable land. The requirements for formation of prices are given due to the need for stability of the mutual relations between the quality of soil and climatic conditions, which manifests...

Assessment of Environment Impact of CAP Reforms on European Agricultural Production Efficiency
Provedor de dados: 31
Autores: Serrao,   Amilcar.
The studies of performance and production efficiency have ignored additional products of most transformation processes classified as undesirable outputs. Without the inclusion of the undesirable outputs, the efficiency measurement is a purely technical measure, and it does not account for the interaction of the system with the environment and the impact of policy decisions on the system. Moreover, there are technological dependencies between the desirable and the undesirable outputs which have to be included in the analytical tools used to measure efficiency.  The relationships between the desirable and the undesirable outputs motivate the exploration of new areas of the measurement of efficiency to incorporate policy decisions and address new issues.

Autores: Pathak, Prabir Kumar; Chander, Mahesh.
Animal welfare has attracted widespread attention worldwide in recent times including within the conventional systems of intensive production in industrialized countries. It can be assessed in a number of ways, also, the yardstick of welfare may differ from people to people and region to region since OIE is only now considering development of more science-based internationally acceptable criteria for animal welfare. In this study, the organic livestock production standards, developed inter alia, the Government of India (GOI) under its National Programme for Organic Production (NPOP), were used to assess the practices being followed at farmers' level in India. Organic production standards are supposed to keep animal welfare as one of the top most...

Provedor de dados: 60
Autores: Jesus,Caroline Regina de; I-Ching,Lee; Neiva,Teresinha de Jesus Carvalho; Vituri,Cidônia de Lourdes.
Chronic Myeloid Leukemia (CML) is a myeloproliferative disease characterized by the presence of the Philadelphia chromosome (translocation between chromosomes 9 and 22), resulting in the formation of the hybrid BCR-ABL protein. Currently, the treatment of CML patients is performed with imatinib mesylate (IM), which promotes the elimination of leukemic cells by inhibiting the kinase activity of BCR-ABL. This study evaluated the effectiveness of IM by monitoring 22 CML patients in a chronic phase treated at the CEPON/SC with IM for a minimum follow-up period of two years. Cytogenetic Response (CR) and bone marrow biopsies (BMB) were evaluated before and after IM treatment. BMB were evaluated by detection of reticulin degree and vascularization. The results...

Autores: Davide,Livia Maria Chamma; Ramalho,Magno Antônio Patto; Figueiredo,Ulisses José de; Souza,João Cândido de.
Maize (Zea mays L.) cultivars with dent grains present higher starch and dry matter ruminal degradability than those with flint grains. This study aimed to assess genetic parameters of degradability in maize grains of different textures and to verify whether there is an association between grain indentation score and ruminal dry matter (RDM) degradability. The evaluated progenies were obtained from the cross between the varieties Cristal (flint) and Cunha (dent), previously selected for grain hardness. Progenies were evaluated for an indentation score using a visual grading scale ranging from 1 (flint) to 5 (dent). To assess the RDM degradability, 5 g were cut into halves, weighed (five grams), stored in bags made of 100% "failet" cloth and incubated for...

Limnoperna fortunei is an invasive gonochoristic and byssate freshwater bivalve originary from Southeast Asia. It shows great adaptive-reproductive ability, so knowledge of the gonadal cycle is an important factor for the prevention and control of this bioinvasion. This species is highly damaging to natural and human environments. We analyzed the distribution and maturity state of reproductive follicles in the mantle of both male and females. Male results are not shown but, in general, they followed the same pattern as that of females. Routine histological techniques included serial longitudinal sections and transversal sections in three body regions (anterior, middle and psoterior). Oocytes with conspicuous nucleoli were measured on both types of sections...

This work aimed to study the oxidation of leaves of Ilex paraguariensis St. Hil, in a process similar to the oxidation of Camellia sinensis, with the purpose of developing new products based on yerba maté. So far, no previous systematic study about the oxidation of yerba maté has been found elsewhere. A Plackett-Burman experimental design was used for the screening of the significant parameters that affected the oxidation. The oxidation was indirectly quantified by following the changes in the product color, water activity, and pH with the time of processing. The factors that most influenced the process were the age of the leaves and the relative humidity of the oxidation chamber. The differences between the treatments were more evident after 3, 6 12 and...

Assessment Of Response To Heart Failure Therapy: Ventricular Volume Changes Versus Shape Changes
Provedor de dados: 17
Autores: Srilakshmi Adhyapak; V.Rao Parachuri.
The prolate ellipsoid left ventricular geometry is crucial for its unique contraction and relaxation patterns. Perturbations in optimal cardiac function preceding overt heart failure ensue when this ellipsoid shape assumes a more spherical configuration. This stage of spherical configuration, prior to overt dilatation, is when therapy should be intensified. The dynamic shape changes during the cardiac cycle of systole and diastole in valvular regurgitations when ventricular volumes are within normal range have proved that shape changes are clearly dissociated from volume changes in the early stages. In the scenario of advanced heart failure, several therapeutic interventions have been tried with variable success. These therapies aim at decreasing the...

Assessment of selenium mineralization and availability from catch crops
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Thorup-Kristensen, Kristian; Young, Scott D.
Selenium (Se) release from four plant species (Indian mustard, fodder radish, Italian ryegrass and hairy vetch) was measured under controlled leaching conditions and in a pot incubation experiment as part of a study of the potential for using these plant species as Se catch crops. Catch crops may reduce Se leaching and, by subsequent release of Se from the plant material, increase the available Se for succeeding crops. Plants grown both without and with Se addition (250 g Se/ha) were tested. In the leaching experiment, frozen plant material was incorporated into soil columns and incubated at room temperature for up to 19 weeks. The results showed that Se concentrations in the leachate were higher when Se-enriched plant material was incorporated in the...

Assessment of the genetic risks of a metallic alloy used in medical implants
Provedor de dados: 74
Autores: Gomes,Cristiano C.; Moreira,Leonardo M.; Santos,Vanessa J.S.V.; Ramos,Alfeu S.; Lyon,Juliana P.; Soares,Cristina P.; Santos,Fabio V.
The use of artificial implants provides a palliative or permanent solution for individuals who have lost some bodily function through disease, an accident or natural wear. This functional loss can be compensated for by the use of medical devices produced from special biomaterials. Titanium alloy (Ti-6Al-4V) is a well-established primary metallic biomaterial for orthopedic implants, but the toxicity of the chemical components of this alloy has become an issue of concern. In this work, we used the MTT assay and micronucleus assay to examine the cytotoxicity and genotoxicity, respectively, of an extract obtained from this alloy. The MTT assay indicated that the mitochondrial activity and cell viability of CHO-K1 cells were unaffected by exposure to the...

Provedor de dados: 42
Autores: Meneghini,Rogério; Gamba,Estêvão C.
Several genome sequencing programs were launched in Brazil by the end of the nineties and the early 2000s.The most important initiatives were supported by the ONSA program (http://watson.fapesp.br/onsa/Genoma3.htm) and aimed at gaining domain in genomic technology and bringing molecular biology to the state of art. Two mainsets of data were collected in the 1996-2007 period to evaluate the results of these genome programs: the scientific production (Scopus and Web of Science databases) and the register of patents (US Patent and Trademark Office), both related to the progress of molecular biology along this period. In regard to the former, Brazil took a great leap in comparison to 17 other developed and developing countries, being only surpassed by China....

Assisting natural forest regeneration in Northern Ethiopia: one intervention is not enough
Provedor de dados: 17
Autores: Raf Aerts; Eva November; Martin Hermy; Jozef Deckers; Mitiku Haile; Bart Muys.
Management strategies aimed at rehabilitating degraded and cleared forests often rely on temporary or permanent exclusion of herbivores (wild animals, livestock or both).  But in many cases, this simple management technique is not sufficient to induce ecosystem restoration: many negative effects keep the ecosystem in a suboptimal, low biomass state.  The presence of such stable states requires restoration measures to act on multiple stress factors simultaneously.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Compensating for all limiting factors is neither practically nor economically feasible.  But detailed knowledge about the autoecology of tree species &amp;#x2013; i.e. their site requirements, regeneration strategies and recruitment dynamics &amp;#x2013; may be...

Association of PPARγ2 polymorphisms with carcass and meat quality traits in a Pietrain x Jinhua F2 population
Provedor de dados: 74
Autores: Chen,Zhe; Zhao,Xiaofeng; Jiang,Xiaoling; Guo,Xiaoling; Lv,Zunzhou; Zhou,Hongmei; Xu,Ningying.
The PPARγ2 gene is a key regulator of both proliferation and preadipocyte differentiation in mammals. Herein its genotype and allele frequencies were analyzed using PCR-SSCP in eight pig breeds (N = 416). Two kinds of polymorphisms of the PPARγ2 gene were detected, including a previously reported shift SNP A177G (Met59Val) in exon 1 and a novel silent mutation G876A in exon 5. The results revealed that European pig breeds carry a higher allele A frequency at the A177G locus and a fixed GG genotype at the G876A locus. Allele A at the G876A locus was only found in Jinhua pigs. The association between haplotype (A177G/G876A) and carcass and meat quality traits was analyzed in a Pietrain x Jinhua F2 population (N = 248). The PPARγ2 gene was found to be...

Association of the borer Spermophthorus apuleiae (Coleoptera; Curculionidae; Scolytinae) with the "pau-ferro" tree Caesalpinia ferrea (Leguminosae)
Provedor de dados: 49
Autores: Suesdek,Lincoln; Lima,Flávio Cesar Thadeo.
The weevil subfamily Scolytinae includes beetles which may feed on the bark, trunk or roots of both live and dead trees and are sometimes considered forest and silvicultural pests. Less frequently, some species feed on seeds and may be cause economic losses when associated to plant cultivars. Spermophthorus apuleiae Costa-Lima is a Neotropical Scolytinae formerly recorded to be "associated" with seeds of Caesalpinia ferrea var. leiostachya Benth, a Brazilian tree popularly known in Portuguese as "pau-ferro". Hitherto, it was not clear whether these beetles actually feed on the seeds of that plant. In order to investigate the ability of S. apuleiae to feed on seeds of "pau-ferro", observations were done and colonies of these beetles were established. Both...

Asymmetric Price Transmission and Non-linear Adjustment in the Iranian Mutton Market
Provedor de dados: 31
Autores: Falsafian,   Azadeh; Yazdani,   Saeed; Moghaddasi,   Reza.
This paper analyses the asymmetric price transmission and non-linear adjustment at the farm and retail levels in the Iran’s mutton market. We applied a multivariate threshold error correction mechanism for monthly price data. We tested the non-linear adjustment using sup-LR, sup-LM and sup-Wald tests. The results confirm the presence of non-linear cointegration relationship between the retail and farm prices. In short-run, the price transmission behavior reveals that reactions of both the retail and farm prices to positive and negative deviations from the long-run price spread are asymmetric. More specially, the retailers show more strong responses to the both positive and negative shocks imposed to the farmers.

Asymmetric Price Transmission in Food Supply Chains: Impulse Response Analysis by Local Projections
Provedor de dados: 31
Autores: Kuiper,   Erno; Bunte,   Frank H.J.
In this paper we set out Jorda’s (2005) method of local projections by which nonlinear impulse responses can be computed without the need to specify and estimate the underlying nonlinear dynamic system. The method is used to compute price reaction functions that show how the prices of the different stages in the supply chain dynamically respond to one another and whether or not these responses reveal any asymmetric patterns. Empirical applications for the US pork-meat and broiler composite chains illustrate the convenience of the method.

Provedor de dados: 95
Autores: Delgado,Liliana Ferreira; Barbedo,Claudio Jose.
Estudos de germinação após o fracionamento de sementes monoembriônicas de diversas espécies de Eugenia demonstraram seu potencial regenerativo. Entretanto, a formação de novas plântulas não ocorre de maneira espontânea em sementes intactas, sugerindo a presença de inibidores de germinação na semente germinante. Para investigar a presença de possíveis inibidores, seis concentrações de extratos de sementes de pitangueira (Eugenia uniflora) foram utilizados em testes de germinação, além do controle (água pura). O possível efeito osmótico desses extratos foram aferidos com soluções de PEG 6000 e de NaCl, de -0,05 a -0,40 MPa. Os extratos de pitanga não apresentaram inibição de germinação para a própria espécie. Contudo, para aquênios de alface e para sementes...

Provedor de dados: 17
Autores: Raji Heyrovska.
The three positron based chemical entities, analogous to hydrogen atom, hydrogen molecule and hydride, are drawing increasing attention in the literature. While a lot is known about the binding energies, not much is known about the radii of the atoms and ions and bond lengths and structures of these exotic entities. This article brings for the first time exact values of these structural properties which are comparable with known data. It is hoped that the results will be of help for a better understanding and further development of the chemistry and physics of these exotic compounds and of their possible role as intermediates in chemical and interfacial processes.

Com vista ao estudo de atração e penetração de Meloidogyne javanica (Treub) Chitwood e Heterodera glycines (Ichinoe) em soja (Glycine max L.), desenvolveu-se uma técnica empregando-se segmento de raiz com 2cm de comprimento. Nos segmentos de raiz de soja infectados, observou-se que a penetração de juvenis de segundo estádio (J2) de M. javanica ocorre pela coifa seguida de migração entre os feixes vasculares do cilindro central. Juvenis de H. glycines penetraram, aproximadamente, 15mm da coifa. A região seccionada da raiz de soja atraiu três vezes mais J2 de M. javanica do que a região da coifa, mas esta não foi tão atrativa para J2 de H. glycines. A obstrução conjunta da coifa e do local seccionado reduziu (83%) a penetração de J2, tanto de M. javanica...

Autores: Roque,Antoniane Arantes de Oliveira; Souza,Zigomar Menezes; Araújo,Fernando Silva; Silva,Gilka Rocha Vasconcelos da.
Com a adoção da colheita mecanizada no sistema de manejo da cana-de-açúcar, surge a preocupação da compactação do solo e seus efeitos danosos na disponibilidade de água às plantas. Uma recente técnica de manejo da mecanização agrícola denominada controle de tráfego representa uma alternativa para o cultivo de cana-de-açúcar, pois separa as zonas de tráfego das zonas em que há crescimento das plantas, concentrando a passagem de pneus em linhas delimitadas. O presente estudo teve por objetivo avaliar o efeito do controle de tráfego em áreas cultivadas com cana-de-açúcar, sobre a qualidade física do solo, no sistema de cana colhida mecanicamente sem queima (cana-crua).

Autores: Costa,Mônica S. S. de M.; Pivetta,Laércio A.; Costa,Luiz A. de M.; Pivetta,Laerte G.; Castoldi,Gustavo; Steiner,Fábio.
O sistema plantio direto (SPD) é uma técnica eficiente no controle da erosão do solo porém alguns estudos indicam a ocorrência de compactação, principalmente na camada superficial. Estratégias que elevem o teor de matéria orgânica, como a rotação de culturas e a adubação orgânica, podem ser utilizadas para resolver este problema. O objetivo do trabalho foi avaliar o efeito de sistemas de manejo (rotação e sucessão de culturas) e adubações (mineral, orgânica e organomineral) sobre as propriedades físicas do solo e a produtividade do milho, de 2006 a 2008. As avaliações foram realizadas em fevereiro de 2007, após a colheita do milho de verão, e em setembro de 2008, após a colheita do milho safrinha. A rotação de culturas promoveu redução na densidade e...

O uso conservacionista do solo tem-se instituído tema de crescentes discussões devido à remoção de biomas e seu posterior uso agrícola. Hipoteticamente, acredita-se que a avaliação da qualidade agronômica de um solo qualquer, por meio de indicadores conjugados, em vez de interpretações isoladas, é mais adequada para caracterização do efeito antrópico em sistemas agrícolas. Em função disso, objetivou-se diagnosticar alterações em um LATOSSOLO VERMELHO-AMARELO Distrófico típico sob monocultivo de soja e cerrado nativo com base em indicadores físicos e microbiológicos, amostrados de modo inteiramente casualizados na profundidade de 0 a 10 cm. Foi possível identificar degradações físico-microbiológicas significativas no ambiente antropizado, com reduções...

Atributos físicos e químicos de área degradada tratada com lodo de esgoto .
Provedor de dados: 14
Autores: SOUZA, M. D. de; LIGO, M. A. V.; SKORUPA, L. A.; PIRES, A. M. M.; FILIZOLA, H. F.
Resumo: O lodo pode fornecer às plantas, em quantidades satisfatórias, com exceção do potássio, todos os nutrientes essenciais para as culturas. A composição química do lodo é de suma importância na recomendação da quantidade a ser aplicada no solo. As recomendações são normalmente baseadas no teor de nitrogênio levando-se em consideração as concentrações de metais pesados presentes na massa de lodo, além da presença de patógenos. Assim, o conhecimento da taxa de mineralização do N orgânico é um dos principais fatores que determinam a quantidade de lodo a ser aplicada no solo. Apesar das vantagens do uso de lodo de esgoto para recuperar áreas degradadas, como apontado pela avaliação de outras variáveis neste estudo, deve ser salientado o inconveniente...

Atributos microbianos do solo após a adição de lodo anaeróbio da estação de tratamento de efluentes de parboilização do arroz
Provedor de dados: 90
Autores: Vieira,Giúlia D'Avila; Castilhos,Danilo Dufech; Castilhos,Rosa Maria Vargas.
O cultivo do arroz é destaque na região Sul, com 60 % da produção total desse cereal no país. A parboilização do arroz é um tratamento hidrotérmico que cozinha parcialmente os grãos ainda em casca, melhorando seu valor nutricional. Desse processo resulta um efluente rico em matéria orgânica e nutrientes, que pode ser utilizado como adubo orgânico na agricultura. O presente trabalho objetivou avaliar a qualidade de um solo com base nas alterações de alguns atributos microbianos decorrentes do acréscimo de lodo anaeróbio da estação de tratamento de efluentes de parboilização do arroz. Foram realizados dois experimentos, sendo o primeiro em casa de vegetação, por meio do cultivo de milho em um Argissolo acrescido de lodo (base seca) nas doses de 2,15; 4,31;...

Attending the First Organic Agriculture Course: Rudolf Steiner’s Agriculture Course at Koberwitz, 1924
Provedor de dados: 21
Autores: Paull, John.
Rudolf Steiner’s Agriculture Course held at Koberwitz (now Kobierzyce, Poland) in 1924 was arguably the world’s first organic agriculture course - although the terms ‘biodynamic agriculture’ and ‘organic farming’ appeared in the decades that followed. Ehrenfried Pfeiffer and others have stated that there were about 60 attendees at the course, while Rudolf Steiner and others have stated that there were about, or more than, 100 attendees. The present study examines the original attendance records to reveal that there were 111 attendees. There were 30 women and 81 men. They came from six countries: Germany (N=61); Poland (N=30); Austria (N=9); Switzerland (N=7); France (N=2); and Sweden (N=2). Of the 60% of enrolees who declared a profession, 38 could be...

Attention induces dynamic changes in coherence between monkey area V1 and V4
Provedor de dados: 17
Autores: Iris Grothe; Simon D. Neitzel; Sunita Mandon; Andreas K. Kreiter.
Neurons receive a vast number of synaptic inputs at the same time. To successfully process a relevant piece of information, a neuron needs to select relevant, while suppressing irrelevant signals. In order to dynamically route a meaningful set of signals through processing pathways, neurons need to have a fast and flexible mechanism to change their effective connectivity. Here, we hypothesize that attention changes effective connectivity by modulating the synchrony between neuronal populations.&amp;#xd;&amp;#xa;We investigated whether attention dynamically changes effective connectivity between area V4 neurons and their V1 input. Single unit activity, multi unit activity and local field potentials (LFP) were recorded simultaneously from macaque...

Attentional control and engagement with digital technology
Provedor de dados: 17
Autores: Tracy Alloway; Ross Alloway.
Multiple demands comprise the efficiency of attentional control. There is abundant evidence that when an individual attempts two or more attentionally demanding activities at the same time, the allocation of attention to the tasks is limited and performance suffers as a result. Yet, recent technological innovations require many individuals to manage multiple digital technologies simultaneously or to switch attentional control between tasks. The ability to multitask with various digital technologies involves dividing attention, switching between tasks, and keeping track of multiple strands of information in working memory.

Attitudes and behaviour towards food attributes and organic food – a triangular methodological investigation of occasional organic consumers
Provedor de dados: 21
Autores: Stolz, Hanna.
Organic food is increasingly available in the conventional food retail, where organic products are offered alongside with various other types of products and compete mainly with conventional and the so-called conventional-plus products. The latter are conventional products displaying particular quality attributes on the product packaging, such as ‘no artificial additives’, or ‘from animal welfare husbandry’. Often, these quality attributes also apply to organic products. Occasional organic consumers might prefer such conventional-plus alternatives that are perceived to be ‘between’ organic and conventional products.   The overall objective of this PhD thesis was to provide information about the segment of occasional organic consumers. In particular, the...

Energy consumption in the United Sates has been increasing and the cost of fossil fuels has been unstable in recent years. Expanding investment in renewable energy is one way to reduce the nation’s dependence on fossil fuels. However, the Not-In-My-Back- Yard (NIMBY) opposition and various concerns raised at public hearings may inhibit the expansion of wind energy in Illinois. This study aims to characterize the public beliefs and opinions toward wind energy in central Illinois.

Autores: Nagamoto,Nilson Satoru; Barbieri,Rafael Forti; Forti,Luiz Carlos; Cardoso,Sandra Regina de Sousa; Moreira,Sinara Maria; Lopes,Juliane Floriano Santos.
Leaves of copperleaf (Acalypha spp.) are greatly accepted by leaf-cutting ants and therefore used to maintain colonies in the laboratory. In order to determine the attractive potential of granulated bait of Acalypha wilkesiana leaves versus citrus pulp, currently used in commercial baits, an evaluation was performed, by using the leaf-cutting ant Atta sexdens rubropilosa as model. The handmade non-toxic baits contained powder (90% w/w) of either citrus pulp or A. wilkesiana were offered simultaneously in the foraging arena until the total loading of one of them. Results showed that copperleaf baits are less attractive than the citrus ones, which invalidates the viability of the substitution.

Auction Experiments and Simulations of Milk Quota Exchanges
Provedor de dados: 31
Autores: Brümmer,   Bernhard; Loy,   Jens-Peter; Requate,   Till.
Since 2000 Germany has introduced a fairly unique market mechanism to trade milk quotas between dairy farms. The two major features are: (1) a quasi auctioning system that produces excess demands which are covered by state reserves free of charge and (2) a price band that is used to exclude highest bids. For both features an experimental design is developed to study the impact in reference to a regular seller’s sealed bid double auction. Results show that both treatments lead to significant misallocations. These are due to the direct impact of regulations and due to an imperfect adjustment of bidding functions. The major goal of the market design to reduce quota prices is reached, however, at significant trade losses.

AUCTIONING OUTCOME-BASED CONSERVATION CONTRACTS
Provedor de dados: 31
Autores: Latacz-Lohmann,   Uwe; Schilizzi,   Steven; Breustedt,   Gunnar.
This paper explores two ideas to enhance the performance of agri-environmental contracting schemes: linking contract payments to environmental outcomes and putting the contracts up for tender. This paper investigates whether there are any gains to be had by combining the benefits of both approaches. Controlled lab experiments were run in two countries, systematically varying the rate at which payments are linked to environmental outcomes. This paper clarifies the conditions under which the benefits from combining tenders with incentive payments outweigh the costs.

Die Verfügbarkeit von ökologisch vermehrtem Saatgut bzw. der Sortenauswahl wird insbesondere bei Gemüse als unzureichend eingestuft. Die verwendeten Sorten sind bei vielen Gemüsekulturen zum überwiegenden Teil Hybriden, die für eine on-farm-Erhaltung ungeeignet sind oder im Falle von aus Zellfusion stammenden CMS-Hybriden nicht mehr fertil und auf Betrieben der Ökolandbauverbände per Richtlinie verboten sind. Diese beiden Aspekte der Saatgutfrage waren maßgebend für die Realisierung dieses Projektes.  Mit dem Ziel, die Eignung der Sorten für den ökologischen Gemüsebau zu prüfen, wurden 164 Saatgutmuster noch verfügbarer Populationssorten der Kulturen Kohlrabi (15), Möhren (86) und Porree (63) am europäischen Saatgutmarkt erworben und als Ausgangsmaterial...

Aumento da disponibilidade de N via deposição atmosférica e fenologia reprodutiva de Habenaria caldensis Kraenzl. (Orchidaceae) no Parque Estadual do Itacolomi (PEIT) - MG, Brasil
Provedor de dados: 49
Autores: Pylro,Victor Satler; Cruz,Eduardo dos Santos; Duarte,Gabriela Frois; Kozovits,Alessandra Rodrigues.
Ao lado do aumento da concentração de CO2, a deposição atmosférica de N é atualmente considerada um dos mais importantes fatores de alteração do funcionamento dos ecossistemas nativos, tendo já provocado drásticas mudanças na composição florística e na ciclagem de nutrientes no hemisfério norte. Entretanto, em sistemas tropicais e subtropicais, pouco se sabe sobre os efeitos do enriquecimento de N via deposição atmosférica, sobre o seu funcionamento. A compreensão da amplitude e da direção das respostas de orquídeas ao aumento da concentração de N disponível pode ajudar a alimentar modelos de dinâmica de populações rupícolas em resposta às mudanças globais. Avaliamos as respostas de floração e frutificação em plantas de Habenaria caldensis Kraenzl....

Aurotriquia adquirida em um canino da raça schnauzer
Provedor de dados: 65
Autores: Palumbo,Mariana Isa Poci; Machado,Luiz Henrique de Araújo; Torres Neto,Rafael.
Alterações adquiridas na coloração da pelagem de cães são raras. Schnauzers miniaturas podem apresentar desenvolvimento idiopático de coloração dourada do pelame, primariamente do tronco, chamada de aurotriquia. O presente trabalho relata a ocorrência de aurotriquia em um cão da raça schnauzer, de três anos de idade, sendo esse o primeiro relato de caso de aurotriquia em schnauzer no Brasil. Por se tratar de alteração de rara ocorrência, torna-se necessária maior atenção a características raciais e um melhor exame físico e anamnese, mesmo se tratando de alteração considerada meramente de fenótipo, pois existem as alterações de coloração bem piores, ligadas a doenças de prognóstico.

Ausweitung der individuellen Bedarfsdeckung mit Öko-Lebensmitteln – Identifikation von Sortimentslücken und produktspezifischen Kaufbarrieren für Öko-Käufer
Provedor de dados: 21
Autores: Buder, Fabian; Hamm, Ulrich.
Trotz weiter Verbreitung ökologischer Lebensmittel kaufen auch an Öko-Produkte gewöhnte Verbraucher den überwiegenden Teil ihrer Lebensmittel weiterhin in konventioneller Qualität. Die Ausweitung der Nachfrage nach ökologischen Lebensmitteln bei diesen Konsumenten bietet daher ein enormes Umsatzpotential für den Öko-Gesamtmarkt. Um das Marketing ökologischer Lebensmittel auf diese Zielgruppe ausrichten zu können sind Kenntnisse über die Gründe notwendig, die dazu führen, dass Öko-Konsumenten bestimmte Lebensmittel in konventioneller Qualität kaufen. Das Ziel des vorliegenden Forschungsvorhabens war es daher, zu ermitteln, ob Lücken in den Sortimenten des Handels bestehen oder ob individuelle Kaufbarrieren Öko-Konsumenten von einer Ausweitung ihrer...

Autores: Wild, Melanie; Demmel, Markus; Brandhuber, Robert; Gronle, Annkathrin; Böhm, Herwart; Lux, Guido; Schmidtke, Knut; Haase, Thorsten.
Die nachhaltige Erhaltung und Steigerung der Bodenfruchtbarkeit ist für ökologisch wirtschaftende Betriebe von höchster Bedeutung. Im Ökologischen Landbau hängt das Niveau der Bodenfruchtbarkeit – abgesehen von den kaum zu beeinflussenden standörtlichen Gegebenheiten – sehr von der Leistungsfähigkeit der Leguminosen ab. Vor allem durch ihre Fähigkeit, Luftstickstoff zu binden und diesen für ihr eigenes Wachstum sowie für die Folgekulturen verfügbar zu machen, bilden Leguminosen die Grundlage der Bodenfruchtbarkeit im Ökologischen Landbau. In der Konsequenz bedeutet dies, dass Beeinträchtigungen der Leistungsfähigkeit der Leguminosen nicht nur deren eigenen Ertrag sondern auch die Leistungsfähigkeit der gesamten Fruchtfolge am Standort begrenzen. Speziell...

Auswirkungen der Grünlandnachsaat in einer Kurzrasenweide bei Biologischer Bewirtschaftung
Provedor de dados: 21
Autores: Starz, Walter; Steinwidder, Andreas; Pfister, Rupert; Rohrer, Hannes; Schmied, Veronika.
Die Kurzrasenweide ist ein geeignetes Weidesystem für die Low-Input Milchviehhaltung und daher auch für die Biologische Landwirtschaft interessant. Weidehaltung bietet nicht nur wirtschaftliche Vorteile, sondern passt auch ideal zu den Werten der Biologischen Landwirtschaft. Bei der Umstellung eines Milchviehbetriebes auf ein Weide basiertes Fütterungssystem müssen vorher als Mähwiesen genutzte Flächen beweidet werden. Durch die Bewirtschaftungsänderung von einer Schnittwiese zur Kurzrasenweide sind Auswirkungen auf den Pflanzenbestand sowie auf die Mengen- und Qualitätserträge zu erwarten. Um diese Hypothesen zu überprüfen, wurde ein 3-jähriger Feldversuch am Bio Lehr- und Forschungsbetrieb des LFZ Raumberg-Gumpenstein von 2007-2009 angelegt. In dieser...

Autores: Pries, Martin; Rauch, Petra; Mersch, Ferdinand; Spiekers, Hubert.
Die im Versuch verabreichten Kraftfuttermengen spiegeln die Befunde aus der Praxis-untersuchung gut wider. Ausschlag gebend für die hohe Milchleistung in beiden Fut-tergruppen sind die Faktoren Grobfutterqualität und Futtertischmanagement, welche zu einer sehr hohen Grobfutteraufnahme führen. Auch in der ökologischen Milchvieh-haltung ergeben sich ökonomische sowie physiologische Vorteile, wenn in der Stall-haltungsperiode die Tiere gemäß ihrem Nährstoffbedarf mit entsprechenden Konzent-ratmengen versorgt werden. Bei Weidegang besteht eine höhere Verdrängung von Grobfutter durch Kraftfutter, so dass sich Einsparmöglichkeiten ergeben. Der einzelbe-triebliche Kraftfutteraufwand sollte ständig in Abhängigkeit des Leistungsniveaus des Betriebes, der...

Autores: Tyystjärvi, Esa; Nørremark, Michael; Mattila, Heta; Keränen, Mika; Hakala-Yatkin, Marja; Ottosen, Carl-Otto; Rosenqvist, Eva.
Automatic identification of crop and weed species is  required for many precision farming practices. The use of chlorophyll fluorescence fingerprinting for identification   of maize and barley among six weed species was tested. The plants were grown in outdoor pots and the fluorescence measurements were done in variable natural conditions.   The measurement protocol consisted of 1 s of shading followed by two short pulses of strong light photosynthetic photon flux density 1700 lmol m-2 s-1) with 0.2 s of darkness in between. Both illumination pulses caused the fluorescence yield to increase by 30–60% and to display a rapid fluorescence transient resembling transients obtained after long dark incubation.

First oceanographic data sets for the Black Sea available via Internet or on the digital data carriers appeared at the end of 1990-th. From this time their number has been growing tremendously. We started to review these data sources in June 1999 and repeated this work with the interval of 1.5 - 4 years. In this review we analyze the marine biological data because availability of this type of data is less known and attract more interest nowadays. We treat lists and check-lists of species as biological data as well although formally they are more metadata or information than data itself. In 1999 only three Black Sea biological data and information sources were available on Internet: (1) Black Sea Red Book that is still on-line at...

This experiment was conducted to determine the requirement of available phosphorus (aP) for pigs kept in hot environment. Seventy-two pigs (36 castrated males and 36 females) with initial weight of 15.10±0.31 kg were allotted in a completely randomized block design with six treatments (0.107, 0.214, 0.321, 0.428, 0.535, and 0.642% of aP), six replicates and two pigs (1 castrated male and 1 female) per experimental unit. Pigs were kept in a hot environment with temperature of 34.1±0.8 ºC. The levels of aP influenced the daily weight gain, which increased quadratically up to the estimated level of 0.477%, and feed conversion, which improved quadratically up to the estimated level of 0.457%. The levels of aP also influenced the content of phosphorus in the...

Avaliação agronômica de forrageiras.
Provedor de dados: 14
Autores: TOWNSEND, C. R.
O desenvolvimento de tecnologias em pastagens requer constantemente pesquisas no sentido de se obter diferentes níveis de conhecimento do comportamento e respostas de forrageiras (gramíneas e leguminosas) a fatores ambientais (abióticos e bióticos), de utilização e manejo. Para tanto, os pesquisadores dispõem de diversos métodos, meios e técnicas, adequados a diferentes circunstâncias e objetivos de pesquisa. Dentre estas alternativas, estão as 'provas agronômicas', ou seja, aquelas cujas principais informações são obtidas mediante cortes e/ou estimativas da vegetação ou em parte desta, com ou sem a introdução do efeito animal. Estas provas geralmente são de baixo custo e de fácil implantação, por isto são bastante difundidas. Muito embora a interpretação...

Avaliação da acurácia de um novo monitor oscilométrico desenvolvido para mensuração da pressão arterial em pacientes veterinários
Provedor de dados: 195
Autores: Rodrigues, J. C.; Teixeira Neto, F. J.; Campagnol, D.; Ozeki, L. M.; Cândido, T. D.
A monitoração da pressão arterial é requerida durante procedimentos cirúrgicos, de pesquisa e atendimento clínico de rotina. A mensuração direta da pressão arterial via cateterização fornece valores mais precisos, porém requer habilidade e não é isenta de riscos, tais como hemorragias, infecções secundárias, dentre outros. Por essas razões, muitos clínicos preferem empregar técnicas indiretas de determinação da pressão arterial na rotina anestesiológica. Clinicamente, os métodos não invasivos são considerados mais apropriados por serem simples e por causarem menos estresse ao paciente. Apesar de serem métodos práticos para avaliação de pressão arterial durante anestesia geral, os monitores Doppler e o Oscilométrico apresentam algumas desvantagens. O...

Avaliação da biodiversidade da Caatinga para controle de nematódeos gastrintestinais de caprinos e ovinos.
Provedor de dados: 14
Autores: NOGUEIRA, D. M.
Na produção animal, a verminose é um dos fatores limitantes da caprinocultura, sendo considerada a principal doença responsável pelas elevadas perdas econômicas no rebanho. Associado a esse problema está o uso indiscriminado de drogas anti--helmínticas alopáticas que é responsável pela seleção de nematódeos resistentes ou de nematódeos que desenvolvem resistência aos anti-helmínticos. Esta atividade teve como objetivos testar diferentes dosagens em caprinos e/ou ovinos de plantas medicinais já citadas na literatura como detentoras de ação anti-helmíntica e avaliar a eficácia das plantas medicinais da Caatinga conhecidas popularmente como anti-helmínticas, porém ainda não citadas na literatura. Foram utilizados caprinos e ovinos mestiços para cada...

Provedor de dados: 14
Autores: SANTOS, R. S. S. dos; LEOLATO, L. S.; GIUSTINA, P. G. D.; SOUZA, R. B. de.
O manejo de insetos-praga em pomares de macieira tem sido realizado pela coleta de informações da tlutuação das populações e adoção de medidas de controle a partir dos limites populacionais máximos toleráveis. Como ferramenta de manejo a estratégia química ainda prevalece na maioria das situações, quando são empregados inseticidas nas doses de registro para a cultura. Em algumas situações, mesmo após a intervenção química, é observada a presença de adultos em armadilhas de monitoramento em avaliações subseqüentes. A Grapholita molesta é um exemplo disto, suas populações, em alguns casos, permanecem elevadas mesmo após uma intervenção de controle, sugerindo resistência de suas populações. Este inseto pela constância de ocorrência ao longo das safras e danos...

Autores: Ritzinger,Cecília Helena Silvino Prata; Fancelli,Marilene; Cordeiro,Zilton José Maciel; Vieira,Rosiane da Silva; Ledo,Carlos Alberto da Silva.
Com a demanda pela produção integrada, o monitoramento torna-se fundamental para reduzir ou substituir insumos poluentes na fertilização e no manejo de pragas. Muitos produtos têm sido aplicados em áreas de produção, sem o devido registro ou conhecimento de sua eficiência ou de seu efeito sobre pragas e inimigos naturais. Nesta região, o uso de organomineral é preconizado como alternativa ao uso de fertilizante e possivelmente com efeito nematicida. As avaliações, para verificar o efeito deste produto, foram realizadas, por meio de cinco coletas, no período de 2008 a 2010, em três propriedades, em bananais, cv. 'Williams', introduzidos há oito e 13 anos, dentro do projeto de Irrigação de Formoso, em Bom Jesus da Lapa-BA. Foram coletadas dez amostras...

Provedor de dados: 14
Autores: SANTOS, R. S. S. dos; LEOLATO, L. S.
Grapholita molesta utiliza a estratégia da diapausa nas estações mais frias do ano, no sul do Brasil. Em hipótese, burrknots de macieira servem como refúgio durante a hibernação. O estudo teve por objetivo avaliar a ocorrência de lagartas de G. molesta em burrknots de macieira das cultivares Fuji e Gala. O trabalho foi realizado em agosto de 2008 e em agosto e outubro de 2009, em pomares de macieira localizados no município de Vacaria, RS. De um total de 616 unidades de burrknots extraídos e analisados no inverno, apenas 0,65% apresentaram lagartas em seu interior e 13,31% vestígios pupais do inseto, o que indica não ser este o sítio preferencial de hibernação da espécie.

Plaquetas são produzidas na medula óssea e são consideradas o principal responsável pela hemostasia primária. Assim, em todos os animais com suspeita de anormalidades hemostáticas, a contagem de plaquetas deve ser realizada rotineiramente (MEYER et al., 1995 e HACKNER, 1995). Existem vários métodos entre manuais e automatizados para realizar a contagem (TASKER et al., 2001), porém a realizada em câmara de Neubauer é considerada o método oficial de referência para a contagem plaquetária pelo Comitê Internacional para Padronização em Hematologia (ICSH) (TASKER et al., 2001), conhecida também como “prova-ouro”. Além do método de contagem aplicado, uma boa coleta é imprescindível para a confiabilidade dos resultados.

Avaliação de cloretos não tamponados como extratores de alumínio associado à matéria orgânica em solos da planície costeira do estado de São Paulo
Provedor de dados: 90
Autores: Coelho,Maurício Rizzato; Vidal-Torrado,Pablo; Otero Pérez,Xosé Luis; Martins,Vanda Moreira; Macías Vázquez,Felipe.
Pirofosfato de sódio é o extrator mais utilizado para a determinação do Al complexado à matéria orgânica do solo (MOS). Devido à sua falta de seletividade para algumas amostras de solos, extratores não tamponados de Cl têm sido recomendados em substituição ao pirofosfato. Com o objetivo de avaliar a eficácia dos cloretos não tamponados de Cu (CuCl2), lantânio (LaCl3) e potássio (KCl) como extratores de Al unido à MOS, analisaram-se amostras de 31 perfis de solos representativos das áreas sob vegetação de restinga do litoral paulista. Os resultados foram comparados àqueles obtidos com pirofosfato de sódio. O CuCl2, mais forte que o LaCl3 e KCl e menos eficaz que o pirofosfato, extraiu parte do Al de compostos inorgânicos amorfos e de complexos Al-húmus...

Os indicadores convencionais de fertilidade de solo, mais comumente utilizados, enfatizam o balanço ácido-base e o conteúdo de elementos químicos, mas não consideram adequadamente as propriedades biológicas do solo, responsáveis por grande parte do seu funcionamento. Os indicadores biológicos, ainda pouco difundidos, levam em consideração a atividade microbiana do solo que é mais sensível à dinâmica do solo. Em Marapanim-PA, e utilizando um desenho experimental inteiramente casualizado, com quatro repetições, avaliou-se o comportamento dos indicadores do solo carbono e nitrogênio da biomassa microbiana, fosfatase ácida, matéria orgânica, carbono orgânico e fósforo disponível, em um solo com cultivo sequencial de mandioca e milho, preparo com...

O uso de defensivos agrícolas na lavoura representa elevação no custo de produção da mesma e produz impacto ambiental indesejado, devido à contaminação do meio ambiente com produtos químicos. Nesse contexto, a utilização de genótipos com resistência a insetos é desejável, apresentando-se como uma alternativa ao uso de inseticidas no campo. Na cultura da soja, sabe-se que os percevejos causam grandes danos, afetando principalmente os grãos, que devido ao ataque de tais insetos, tornam-se manchados, deformados e até mesmo inviáveis.

Autores: Inoue,Luis Antonio Kioshi Aoki; Boijink,Cheila Lima; Ribeiro,Patrizia Teixeira; Silva,Ana Maria Dias da; Affonso,Elisabeth Gusmao.
O tambaqui é a principal espécie de peixe cultivado na Amazônia Ocidental. Porém durante o processo produtivo, práticas de manejo são necessárias para o monitoramento do crescimento e estado geral da sanidade dos animais. Para isso os animais devem ser anestesiados para maior segurança no trabalho. O eugenol, componente majoritário do óleo de cravo, tem sido bastante utilizado como anestésico alternativo para peixes por ser um produto natural e de baixo custo. Entretanto, estudos tratando de respostas metabólicas em peixes tropicais expostos a diferentes anestésicos são ainda necessários. Dentro desse intuito, o presente trabalho avaliou respostas metabólicas, detectadas por meio de alterações de parâmetros sanguíneos e plasmáticos do tambaqui, exposto ao...

Avaliação de Risco em Investimentos Florestais
Provedor de dados: 190
Autores: Simioni, Flávio José; UNIPLAC; Hoeflich, Vitor Afonso; Embrapa Florestas.
A avaliação econômica de projetos de investimentos é comumente utilizada como forma de buscar parâmetros indicativos de sua viabilidade. Entretanto, as condições de incertezas em relação ao ambiente econômico dificultam o processo de tomada de decisão. No caso dos plantios florestais, a complexidade é ainda maior em função do alto tempo de retorno do investimento. Uma das alternativas que pode ser utilizada pelos investidores é a transformação das incertezas em risco. Assim, o objetivo do artigo é verificar a adequação do emprego do Método de Monte Carlo (MMC) na avaliação do risco em plantios florestais de Pinus spp. O procedimento consiste na simulação da Taxa Interna de Retorno (TIR) e do Valor Presente Líquido (VPL) do projeto, a partir da simulação de...

A micropropagação de plantas é extremamente útil na multiplicação de novas cultivares em larga escala. O abacaxizeiro 'Vitória' é uma cultivar com a importante característica de ser resistente à fusariose. Após cultivo in vitro e aclimatização, é possível produzir mudas de diferentes tamanhos, entretanto um tamanho-padrão tem sido utilizado para comercialização. O uso de mudas de diferentes estádios de crescimento, após a aclimatização, pode interferir na qualidade final das mudas para o plantio no campo. O objetivo deste trabalho foi avaliar o efeito dos diferentes tamanhos de mudas do abacaxizeiro 'Vitória', após aclimatização, na qualidade dessas após o período de aclimatação.

A babesiose equina é uma doença causada pelos protozoários Theileria equi e Babesia caballi que frequentemente estão associados. A transmissão se dá principalmente por carrapatos (KNOWLES, 1983). Por ser uma doença intra-eritrocitária, causa problemas que diminuem a “performance” de animais atletas, além de prejuízos decorrentes de gastos com tratamento, abortos e mortes devido a infecções agudas ou congênitas (FRIEDHOFF, 1990). O tratamento recomendado para infecções de Babesia caballi é com Dipropionato de Imidocarb na dose de 2,2 mg/kg im, repetida após 24 horas. O rim regula a homeostase corporal, tem função excretória e reguladora de produtos finais do metabolismo e é a principal via de eliminação dos medicamentos. Sua função pode ser verificada...

Provedor de dados: 195
Autores: Carandina, L. S.; Araújo, M. M.; Carmagnani, T. C.; Coelho, V. S.; Coutinho, A. S.
A ingestão de substâncias cáusticas e corrosivas é ainda motivo de preocupação na medicina veterinária pela gravidade dos casos e pela grande ocorrência. Esse fato está relacionado ao fácil acesso dessas substâncias, que acarretam a gastrite aguda, levando à inflamação da mucosa gástrica e lesões ulcerativas. Outras causas comuns de gastrite aguda podem estar relacionadas à ingestão de materiais químicos, plantas tóxicas e intolerância alimentar ou alergia. O diagnóstico precoce é de suma importância. A avaliação clínica deve incluir lábios, mucosa oral, assoalho da boca, língua, palato, faringe e laringe, sendo também imprescindível a avaliação do esôfago, estômago e primeira porção do duodeno pela endoscopia digestiva alta.

Avaliação fenológica de frutos de café a partir da quantificação da expressão de genes marcadores - proposta de uma ferramenta complementar.
Provedor de dados: 14
Autores: MALUF, M. P.; GUERREIRO FILHO, O.
Entre as técnicas de biologia avançada, as que permitem a quantificação da expressão de genes em diversas situações biológicas têm tido importância crescente para Programas de Melhoramento. Essas técnicas, entre outras coisas, permitem avaliar genes-candidatos para transferência para outras plantas, genes que servirão como marcadores para seleção assistida de características desejáveis, ou então selecionar genes-marcadores que servirão para marcar uma fase de desenvolvimento específica. Uma das dificuldades para seleção de cafeeiros com características organolépticas definidas é a definição das fases fenológicas durante a frutificação do cafeeiro, associadas com os processos fisiológicos de maturação e amadurecimento dos frutos. Este documento, de cunho...

Autores: Gonçalves,F.M; Pires,A.V; Pereira,I.G; Garcia,D.A; Farah,M.M; Meira,C.T; Cruz,V.A.R.
Estimaram-se as herdabilidades para os efeitos genéticos direto e materno e as correlações genéticas entre essas variáveis para os pesos ao desmame (P205), ao ano (P365) e ao sobreano (P550) em um rebanho Nelore do norte de Minas Gerais. O modelo estatístico incluiu os efeitos aditivos direto e materno, os efeitos fixos de grupo de contemporâneos (fazenda, sexo, regime alimentar, estação (seca e água) e ano de nascimento do animal) e o efeito da covariável idade da vaca ao parto (linear e quadrático). Os componentes de variância e os valores genéticos foram estimados utilizando-se o método REML. A tendência genética foi obtida utilizando-se a regressão do valor genético médio anual em relação ao ano de nascimento dos animais. As estimativas de...

Avaliação histológica do grau de osteoartrite em cães com displasia da articulação do coxal
Provedor de dados: 195
Autores: Coelho, V. S.; Xavier, J. G.; Prada, T. C.; Araujo, M. M.; Carandina, L. S.; Zanco, N. A.; Coutinho, A. S.
A displasia da articulação do coxal (DCF) implica-se diretamente como uma das doenças mais observadas nessa região em cães, principalmente nas raças de grande porte, por apresentarem crescimento rápido. O diagnóstico da DCF é fidedigno através do exame radiográfico com as diferenciações do grau pelo índice de Norberg. Esse índice relaciona diretamente o nível da incongruência articular, associado à presença de Osteoartrite (OA) secundária à DCF. Uma das possibilidades de tratamento empregada é a cirurgia de colocefalectomia, por permitir o retorno do animal à função. Essa articulação é um importante meio de estudo histológico do grau de DCF e, também, da OA. O objetivo do estudo foi verificar as alterações histológicas na cabeça do fêmur e, também, a...

Avaliação histopatológica da margem cirúrgica no transoperatório associado à eletroquimioterapia em mastocitoma em cão
Provedor de dados: 195
Autores: Paiva, C. V.; Bertolacini, L.; Parra, A. C.; Peluso, T.; Oliveira, D. K.; Rangel, M. M.M.; Romano, L.
A avaliação histopatológica no transoperatório é realizada nos casos em que o cirurgião precisa decidir entre um procedimento simples ou um mais radical. A lentidão do processo convencional torna impraticável a avaliação transcirúrgica de uma lesão suspeita e, tratando-se de neoplasia maligna, esse fator pode ser decisivo entre o sucesso e o fracasso no tratamento. Neste cenário, pode-se lançar mão da eletroquimioterapia, permitindo que os impulsos elétricos atuem como meio de transporte das drogas para o interior das células afetadas sem comprometer o tecido saudável adjacente. O mastocitoma é uma neoplasia maligna considerada como o tumor de pele de maior incidência em cães, sendo graduado de um a três, de acordo com sua diferenciação. Apesar de ser bem...

O sistema convencional do cultivo de flores vem causando diversos problemas, como intoxicações, contaminação dos solos, das águas e alimentos. O objetivo deste trabalho foi avaliar o efeito de extratos vegetais sobre o desenvolvimento de fitopatógenos em flores. Os fitopatógenos Fusarium sp. e Botrytis sp. foram isolados de flores de Gerbera sp. e Rosa sp. com sintomas de doença. Foram avaliados os extratos acéticos e etanólicos de alecrim, cavalinha, gengibre, alho, camomila, louro, manjericão, menta e eucalipto. Observou-se que o extrato etanólico de camomila inibiu em 52% o crescimento micelial de Fusarium sp. O fungo Botrytis sp. foi inibido com os extratos acéticos de alecrim, eucalipto e menta. O potencial antifúngico, parcial ou total, dos extratos...

Autores: Lima, A. F.M.; Schmidt, E. M.S.; Dias, R. G.S.
época do ano e condições de manejo dos animais. Ancylostoma caninum é um nematódeo hematófago do intestino delgado de cães cuja principal forma de infecção é pela passagem de larvas pelo leite de cadelas lactantes contaminadas. Apesar de os animais jovens serem os mais comumente acometidos, ao longo da vida do animal a infecção continua pela penetração cutânea e ingestão de larvas juntamente com alimentos e água4. Toxocara canis é frequentemente encontrado no intestino delgado de cães. A principal via de infecção é pela passagem de larvas via transplacentária, que se encontram encistadas nos tecidos das cadelas gestantes. Assim, aproximadamente 80% dos cães com menos de seis semanas de idade possuem o parasito em seus intestinos, podendo ou não eliminar...

Autores: Andrade, Guilherme de Castro; Bognola, Itamar Antonio; Bellote, Antonio Francisco Jurado; Franciscon, Luziane; Waterloo, Maarten Johannes; Bruijnzeel, Leendert Adriaan.
No Brasil os plantios florestais ocupam 7 milhões de hectares que correspondem a 1% do território (68% com plantações de Eucalyptus e 25% com Pinus) O objetivo desse trabalho foi avaliar plantios de Eucalyptus urograndis. Estoques elevados de Ca e Mg no solo, sugerem uma lixiviação do calcário. A resistência do solo até os 60 cm de profundidade na linha de plantio foi menor do que na entrelinha, indicando que a subsolagem foi eficiente. Os valores de resistência do solo foram mais altos na entrelinha, distante 1 m da linha de plantio, até os 20 cm de profundidade, provavelmente pelo aumento da compactação na preparação da área. A biomassa da copa das árvores diferiu entre as classes de DAP, justificando o uso de equação para a sua estimativa. A variação...

Avanços na bananicultura brasileira
Provedor de dados: 94
Autores: Lichtemberg,Luiz Alberto; Lichtemberg,Paulo dos Santos Faria.
A bananicultura brasileira passou por transformação a partir do início do século passado, com o início das exportações do litoral paulista para o mercado platino e europeu. Ações da Secretaria da Agricultura de São Paulo permitiram uma mudança do simples semi-extrativismo para uma bananicultura com uso de técnicas agronômicas de manejo cultural, adubação e fitossanidade. A partir da década de 50, o Instituto Agronômico e o Instituto Biológico de São Paulo intensificaram as pesquisas com o cultivo da bananeira.

Avanços na cultura da macieira no Brasil
Provedor de dados: 94
Autores: Petri,José Luiz; Leite,Gabriel Berenhauser; Couto,Marcelo; Francescatto,Poliana.
A cultura da macieira no Brasil iniciou seu desenvolvimento comercial na década de 70, sendo que até esta data foram poucos os plantios comerciais, representando menos de 100 ha. Com a iniciativa de alguns produtores pioneiros, incentivos fiscais que permitiam aplicar parte do Imposto de Renda na implantação de pomares e pelo apoio dos governos estaduais com projetos de desenvolvimento, a cultura da macieira teve grande impulso a partir da década de 80. Destaca-se que, na década de 70, o Brasil dependia de importações, representando na época mais de 100 milhões de dólares. Nessa década, produzíamos 13.263 t, passando para 183.299 t e 857.615 t na década de 80 e 90, respectivamente. Atualmente, o Brasil conta com uma área em torno de 37.000 ha, com 3.450...

Avanços na fruticultura tropical no Brasil
Provedor de dados: 94
Autores: Meletti,Laura Maria Molina; Sampaio,Aloísio Costa; Ruggiero,Carlos.
Os principais aspectos que marcaram a evolução técnica das culturas do abacaxizeiro, mamoeiro e maracujazeiro no Brasil foram discutidos. Em abacaxizeiro, tem-se constatado uma inovação no sistema de comercialização da cv. Smooth Cayenne, que consiste no uso de caixas de papelão ondulado para o mercado interno, cujo objetivo é propiciar uma garantia de sabor inserida em uma marca. O recente lançamento de cultivares resistentes à fusariose, pela Embrapa (Imperial e Vitória) e IAC (Fantástico), traz novas perspectivas de produtividade. Em maracujazeiro, a maior contribuição aos pomares foi dada pelo melhoramento genético, inicialmente voltado apenas para ampliação da produtividade da cultura. No início dos anos 2000, o lançamento das primeiras cultivares de...

Avian biogeography on western Indian Ocean islands: eustatic sea levels, geological events and anthropogenic changes
Provedor de dados: 16
Autores: Hume, J.P.
The south-western Indian Ocean islands, excluding the microcontinent of Madagascar, are geologically complex and diverse. They have been subject to drastic sea level changes, volcanic events and anthropogenic changes, all of which have contributed to confuse understanding of their avian biogeography. An array of factors have affected these avifaunas, based on palaeontological, historical and molecular evidence,which together have shown that avian biogeography is not congruent with the relative age and size of the islands.

Autores: Sopeña, Mauro Barcellos; Ramos, Fernando de Souza.
O presente artigo está baseado em pesquisa de estágio profissional realizada em 2011, na Agrosul Agroavícola Industrial, empresa situada no município de São Sebastião do Caí, Rio Grande do Sul. O estudo foi desenvolvido em diferentes setores produtivos da avicultura de corte e pôde verificar in loco aspectos da estrutura produtiva do setor. A observação direta dos processos e das transações da empresa permitiu que, a partir de uma abordagem institucional, se determinasse com mais clareza que arranjos produtivos são criados naquele setor. Em sentido amplo, a agroavícola opera em meio a uma cadeia produtiva importante, com baixos custos de transação. A verticalização está fortemente presente em muitas operações da firma e não se verifica comportamento...

Autores: Cruz,Bruna Botti; Piratelli,Augusto João.
Este estudo teve como objetivo caracterizar a avifauna associada ao rio Sorocaba, um típico rio urbano, do sudeste do Brasil. Ele atravessa a cidade com o mesmo nome, ao longo do qual, várias atividades humanas são realizadas como recreação e pesca. Lá, várias espécies de aves devem encontrar locais para descanso, alimentação e nidificação. As aves foram observadas semanalmente, de setembro de 2008 a setembro de 2009 por meio de 16 pontos fixos (A1 a A16). O levantamento quantitativo registrou 65 espécies (32 passeriformes e 33 não - passeriformes), sendo que a família mais bem representada foi Tyrannidae (n = 9). As espécies mais freqüentes foram Egretta thula, Amazonetta brasiliensis, Vanellus chilensis, Pitangus sulphuratus, Ardea alba e Pygochelidon...

Autores: Andrade, Fabiano Timóteo de; Fisch, Simey Thury Vieira; Fortes Neto, Paulo; Batista, Getulio Teixeira.
As florestas tropicais brasileiras em especial a floresta Atlântica e Amazônica foram e continuam sendo alvos constantes de diversas ações antrópicas humanas, que ocasionaram a redução de seus territórios ou ainda sua total fragmentação. Um dos dados mais alarmantes é a perda de sua biodiversidade, que em muitas situações sequer foi conhecida, o que demanda a preocupação com a manutenção sustentável, de forma que várias espécies ainda possam sobreviver. Através de levantamentos na literatura especializada com o tema “o uso de biondicadores na qualidade ambiental em florestas tropicais”, foram elencados os mais utilizados para esse tipo de avaliação com enfoque na avifauna, uma vez que a mesma responde positiva ou negativamente a qualquer fator que altere...

Autores: Vogel, Huilquer Francisco; Universidade Estadual do Centro-Oeste; Metri, Rafael; Universidade Estadual de Maringá; Zawadzki, Claudio Henrique; Universidade Estadual de Maringa; Moura, Maurício Osvaldo; Universidade Estadula do Centro-Oeste.
This study examined the structure and species richness of the avifauna in CEDETEG campus of Universidade Estadual do Centro-Oeste (Unicentro), in the urban area of Guarapuava, at Paraná State. Data were monthly taken from July 2006 to June 2007 using transects. A total of 125 bird species belonging to 42 families and 16 orders was recorded. The absence of large frugivorous species reveals the destabilization of native vegetation, evidencing that the current floristic structure does not support more specialized species. However, from the total amount of registered birds, 47 (38%) are related to the forest environment in the study area and 25 species (20%) are exclusive of this environment, pointing out the strong relevance of this campus for the...

Az Agrárgazdasági Tanács állásfoglalása az agrárgazdaság 2010 évi helyzetéről
Provedor de dados: 31
Autores: Popp,   Jozsef; Szekely,   Csaba.
Összefoglalóan megállapítható, hogy 2010-ben kedvező fejlemény a gazdálkodók jövedelemhelyzetének javulása, valamint a növekvő mezőgazdasági és élelmiszer-ipari külkereskedelmi mérleg. Ugyanakkor továbbra is aggodalomra ad okot a kivitel és behozatal termékszerkezetének alakulása (feldolgozott termékek importhányada magas, exporthányada alacsony), a foglalkoztatás csökkenése, a növénytermelés és az állattenyésztés aránya, valamint a csökkenő támogatások hatására negatív jelenség volt a beruházások visszaesése. A jelentés pontos képet ad az élelmiszer-gazdaságról, azaz a termékpályáról, a dezintegráció és a nemzetközi versenyképesség problémáiról. A termékpálya szereplői mindaddig ki lesznek téve a hektikus ármozgásoknak, amíg nem jön létre közöttük bizalmi...

Az egykulcsos személyi jövedelemadó várható hatásai az agrárfoglalkoztatásra

Autores: Horvath,   Gabor; Paragi,   Marton.
A személyi jövedelemadó rendszert érintő 2011. évi változásokkal kapcsolatban elhangzott vélemények és értékelések rendkívül egysíkúak. A változások és az eredmények bemutatásakor az adózó magánszemélyt állították a középpontba, a magánszemélyeket érő pozitív és negatív hatásokat összevetve, s így mérleget vonva. Az intézkedések gazdaságpolitikai dimenzióit ugyanakkor figyelmen kívül hagyták: az ágazati szinten megnyilvánuló hatások számszerűsítése, illetve a makrogazdasági következmények összegzése és bemutatása nem történt meg. Az szja-változásokból fakadó nettóbér-csökkenést a munkáltatóknak kompenzálniuk kell. Az intézkedéssel jól járó munkavállalók ugyanakkor kizárólagosan élvezik nettó bérük növekményének hasznát. Ez ágazati szinten azt jelenti, hogy...

Az élelmiszer-ipari vállalkozások környezeti teljesítménye és a pénzügyi eredmények

Autores: Deak,   Zsuzsanna; Hajdu,   Istvanne.
Kutatásunk célja fényt deríteni arra, hogy a vállalkozások környezeti teljesítménye befolyásolja-e pénzügyi teljesítményüket, továbbá az, hogy milyen szerepet játszik ebben a média, hogyan változott az elmúlt időszakban a vállalkozások zöld erőfeszítéseinek megítélése? Megállapítható, hogy azokban a vállalkozásokban, amelyekben a média és a befektetők környezeti teljesítményüket kedvezően ítélik meg, magasabbak a megtérülési (ROE) mutatók, mint azokban, amelyeknek környezeti teljesítményét nem ítélik meg pozitívan. A magyarországi társadalomban a nem anyagi értékek iránti érzékenység és a környezettudatosság alacsony szintű. A társadalmi értékrendben alárendelt szerepet játszó környezetvédelmi gondolkozásra – reklámérték híján – a média mérsékelten hat. Ez...

Az élelmiszerlánc szereplői közötti kapcsolatok hazánkban
Provedor de dados: 31
Autores: Popp,   Jozsef; Juhasz,   Aniko.
Hazánkban a válság miatt a keresleti oldalról növekedni képtelen piacon a kiskereskedelmi szereplők a kötelező éves növekedést immár csak a piac újraosztásával érhetik el, ami a kiskereskedők között kíméletlen – horizontális – versenyt eredményez. Ennek eszköze az alapvető termékek esetében a minél alacsonyabban tartott ár. Ezért a kereskedelmi láncok és beszállítóik kapcsolata vegyes képet mutat. A nagy, tőkeerős, elsősorban nemzetközi élelmiszer-feldolgozók és mezőgazdasági beszállítók számára még így is jövedelmező lehet a kereskedelmi láncok által biztosított széles körű piaci jelenlét. Ezzel szemben a hazai szinten nagy, de nem elég tőkeerős hazai beszállítók alkupozíciója rendkívül kényes, számukra még veszteség mellett is létkérdés a kereskedelmi...

Autores: Solymos,   Rezso.
„Kísértet járja be Európát és Észak-Amerikát: az erdőpusztulás kísértete.” Ezzel a drámai hangvételű mondattal kezdődik a World Resources 1986. évi kötetének erdőkkel foglalkozó része, ami a 70-es években kezdődött nagyarányú erdőpusztulás világméretű „jajkiáltása” volt, melynek visszhangja: „Mentsétek meg a Föld erdeit – amíg nem késő, amíg van mit megmenteni és megőrizni!” Nemzetközi tudományos, világméretű társadalmi fórumok témájává vált az erdő. Az emberiség egyre jobban ráébredt arra, hogy az erdő az emberiség létfeltételeinek elengedhetetlen része. Ebben nagy jelentősége volt a Római Club állásfoglalásának a növekedés határairól. A Stockholmban rendezett első környezetvédelmi világértekezlet, majd a Brundtland Bizottság közös jövőnkről készített...

Az ökológiai gazdálkodás költség-jövedelem viszonyai

Az ökológiai gazdálkodás költség-jövedelem viszonyait a hagyományos termeléssel összehasonlítva, modellszámítások alapján vizsgáltuk. A modellépítéshez szükséges adatokat Hortobágy térségében működő egyéni gazdálkodók körében gyűjtöttünk. Az egy hektárra jutó költségek összegében a két gazdálkodási mód között jelentőseltérések nem voltak, a költségek szerkezete azonban markáns különbségeket mutatott, amely a technológiák eltéréseivel magyarázható. Az ökológiai növénytermelésben a hozamok jellemzően alacsonyabbak voltak, az önköltség és az értékesítési árak viszont magasabbak. Egyik termelési mód sem bizonyult életképesnek támogatások nélkül, a bruttó jövedelem különbségeit azonban nem a támogatások, hanem elsősorban az eltérő hozamok és értékesítési árak...

Bacteria have transient influences on marine corrosion of steel
Provedor de dados: 17
Autores: Robert E. Melchers; Robert Jeffrey.
The contribution of bacteria to the corrosion mass loss and to pitting of mild steel was observed over 2.5 years using parallel streams of unpolluted natural (biotic) and nominally sterilized (abiotic) Pacific Ocean coastal seawater. As also observed by others, in artificial laboratory exposures, corrosion mass loss within the first few days of exposure was much greater in the biotic stream. However, after only about 10 days the difference in mass losses were gradually reduced and were very similar up to about one year of exposure. Thereafter, the corrosion loss in the biotic stream again became more severe. Pitting corrosion in the biotic stream was more severe from the very first exposure throughout the 2.5 years. Corrosion in both seawater streams...

The present study aimed to describe the bacterial community present at an anaerobic up flow bioreactor with ANAMMOX activity, inoculated with the sludge from the anaerobic pond of a swine slurry treatment system. The description was based on the molecular DNA techniques using primers for amplification of complete 16S rRNA gene and also new primers to amplify smaller fragments from 16S rRNA. During the bioreactor operation time, the bacterial community changed significantly, increasing the nitrogen removal efficiency, reaching after 500 days a removal rate of 94%. The complete PCR amplification of 16S rRNA gene generated 17 clones, where three presented similarity with Candidatus Jettenia asiatica (97%), twelve with Janthinobacterium (99%) and two with...

Bacterial colonization of winter flounder Pseudopleuronectes americanus fed live feed enriched with three different commercial diets
Provedor de dados: 5
Autores: Seychelles, L. H.; Audet, C.; Tremblay, R.; Lemarchand, K.; Pernet, Fabrice.
The proliferation of bacteria in intensive aquaculture systems may be responsible for poor growth and mass mortality of marine fish larvae. Essential fatty acids provided in the diet could protect larvae by modulation of the immune response via arachidonic acid (AA) and eicosapentaenoic acid (EPA). Winter flounder Pseudopleuronectes americanus larvae were fed rotifers Brachionus plicatilis enriched with three commercial diets containing different fatty acid profiles. Bacterial colonization on the gills and skin and in the intestinal lumen was evaluated at the end of the rotifer feeding period (day 26), and growth was surveyed until metamorphosis. At 26 days post hatching, larvae fed rotifers containing the higher AA content and with a higher...

Autores: Galdiano Júnior,Renato Fernandes; Pedrinho,Eliamar Aparecida Nascimbém; Castellane,Tereza Cristina Luque; Lemos,Eliana Gertrudes de Macedo.
Bactérias produtoras de auxinas habitam raízes de orquídeas e podem trazer benefícios para a planta hospedeira. Plantas dessa família são multiplicadas em condições assimbióticas in vitro e pouco se conhece sobre a função desses microrganismos para a aclimatização ex vitro. Quatro rizobactérias isoladas da espécie Cattleya walkeriana foram avaliadas por sua capacidade de promoção do crescimento e sobrevivência de plântulas germinadas in vitro durante a aclimatização. Essas rizobactérias foram identificadas como Bacillus, Burkholderia, Enterobacter e Curtobacterium, com base no sequenciamento do gene 16S rRNA. A presença de compostos indólicos no sobrenadante filtrado de culturas líquidas foi quantificada por ensaios colorimétricos e cromatografia líquida...

Provedor de dados: 58
Autores: Teixeira,Mariana Carolina; Santana,Natália Fernanda; Azevedo,Júlio César Rodrigues de; Pagioro,Thomaz Aurélio.
Since the introduction of the Microbial Loop concept, many studies aimed to explain the role of bacterioplankton and dissolved organic carbon (DOC) in aquatic ecosystems. Paraná River floodplain system is a very complex environment where these subjects were little explored. The aim of this work was to characterize bacterial community in terms of density, biomass and biovolume in some water bodies of this floodplain and to verify its temporal variation and its relation with some limnological variables, including some indicators of DOC quality, obtained through Ultraviolet-visible (UV-VIS) and fluorescence spectroscopic analysis. Bacterial density, biomass and biovolume are similar to those from other freshwater environments and both density and biomass were...

Baixando à Terra: uma análise crítica de um projeto de comercialização de produtos florestais não madeireiros em uma comunidade da Amazônia Oriental
Provedor de dados: 190
Autores: Herrero-Jáuregui, Cristina; Pokorny, Benno; Casado, Miguel A.
Muitas organizações governamentais e não governamentais (ONGs) investem esforços consideráveis para apoiar as populações dependentes da floresta, na extração e comercialização de produtos florestais não madeireiros (PFNM), para gerar ganhos econômicos de forma ecologicamente sustentável. Porém, o sucesso destes esforços agora tem sido bastante modesto, sendo que muitas das iniciativas que recebem apoio externo são abandonadas quando o apoio acaba. Este artigo é uma reflexão crítica sobre as expectativas e as preocupações que surgem deste tipo de projetos de desenvolvimento, analisando em profundidade um projeto para a comercialização de óleos vegetais pela comunidade de Pedreira, situada na Amazônia Oriental Brasileira, que tem recebido apoio intensivo por...

Autores: SUJAYA, I-Nengah; MIKUMO, Dai; ORIKASA, Yoshitake; URASHIMA, Tadasu; ODA, Yuji; 浦島, 匡; 小田, 有二; 折笠, 善丈.
Twenty-two strains of Saccharomyces cerevisiae isolated from tape-mash for the production of brem, a traditional rice wine from Bali, Indonesia, were divided into three groups (I, II, and III) based on the sequences of the rDNA spacer region and SUC2 gene. DNA analyses suggested that the seventeen strains in groups II and III were taxonomically closer to baking strains than the five strains in group I. These differences were reflected in their leavening ability in dough with and without addition of 5% sucrose, and their α-glucosidase activity, although most of the strains did not leaven dough with addition of 30% sucrose. Strain S-10 in group II showed a high rate of CO2 production from sponge dough without addition of sugar and consumed fermentable sugar...

Balance crítico del plan de gobierno de Rafael Correa (Coyuntura)

Autores: Moncayo Gallegos, Paco.
Comienzo por aclarar que mi análisis parte de una posición ideológica cercana con la propuesta política de Alianza País. No puede ser de otra manera, dadas mis profundas convicciones social-demócratas, lo que no implica la inexistencia de algunas importantes diferencias. Por las coincidencias ideológicas, apoyé decididamente el proceso de construcción participativa de la Constitución de 2008, en el período en que la Asamblea estuvo dirigida por Alberto Acosta. Posteriormente expresé mis preocupaciones por la forma irregular con que los asambleístas de Montecristi concluyeron su trabajo y aprobaron la Carta Magna. No obstante, motivado por la consciencia de la necesidad de cambios profundos en nuestro país, respaldé su aprobación en el referéndum.  No omito...

Balance político del gobierno de Rafael Correa : nudos críticos y temas polémicos (Especial)
Provedor de dados: 122
Autores: Borja, Raúl.
La visión cíclica de la historia de las sociedades reconoce implícitamente que los cambios que se procesan en éstas tienen un carácter en el mejor de los casos evolutivo, de maduración de las condiciones del nuevo ciclo en “el seno” del anterior, de modo que casi siempre hay una sucesión de hechos y procesos que se cumplen en periodos de mediano plazo. En este caso, metodológicamente se impone primero una comparación de “avances” y “retrocesos” en el ciclo en cuestión, con respecto a los anteriores, método que surte a la postre el efecto de un balance del proceso. En una retrospectiva de la historia política del Ecuador de apenas medio siglo, se puede identificar una sucesión de ciclos en el proceso de cambios de régimen económico y político. El actual es...

La publicación del número 11 de la revista coincidirá con el momento de la consulta y el  referéndum, puesta a trámite en la Corte Constitucional por el Gobierno Nacional, con la intención de superar los problemas de la Función Judicial y así responder a la inseguridad ciudadana que se vive a diario en las principales ciudades del Ecuador. El Gobierno pretende con esta consulta obtener el apoyo del voto popular para realizar cambios constitucionales y legales, como la caducidad de la prisión preventiva, y cambios institucionales, como la reestructuración de la administración de la justicia, a fin de facilitar –según el régimen– el combate a la inseguridad pública.

Balancing noise and plasticity in gene expression
Provedor de dados: 17
Autores: Djordje Bajic; Juan F. Poyatos.
Coupling the control of expression stochasticity (noise) with the capacity to expression change (plasticity) can constrain gene function and limit adaptation. Which factors contribute then to modulate this coupling? Transcription re-initiation is generally associated with coupling and this is commonly related to strong chromatin regulation. We alternatively show how strong regulation can however lead to plasticity uncorrelated to noise. The character of the regulation is also relevant, with plastic but noiseless genes usually subjected to broad expression activation whereas plastic and noisy genes experience targeted repression. This differential action is similarly noticed in how histones influence these genes. In contrast, we find that translational...

Neste trabalho teve-se como objetivo a obtenção dos coeficientes de desoxigenação (K1) e reaeração (K2), no rio Turvo Sujo, em diferentes épocas do ano, e a comparação dos valores de K2 obtidos e estimados por meio de equações baseadas em variáveis hidráulicas. Para isso, realizaram-se coletas de água e medições de vazão em quatro épocas do ano. O coeficiente K1 foi obtido pelo ajuste de regressão não linear e os valores de K2 por meio da equação de Streeter &amp; Phelps. Observou-se que os valores estimados de K1 estão dentro dos valores citados na literatura para rios com águas limpas e, ou, efluentes secundários. Os valores de K2 aproximaram-se dos valores típicos de grandes rios com velocidade normal. Na época chuvosa, os valores de K1 foram mais altos...

Autores: Ludwig,Marcos Paulo; Maia,Manoel de Souza; Corrêa,Marciabela Fernandes.
As sementes de aveia preta (Avena strigosa Schreb.) possuem a capacidade de permanecer viáveis no solo de um ano de cultivo para outro. Dessa forma, o objetivo do trabalho foi avaliar o número de sementes de aveia preta resultantes de dois sistemas de manejo (colheita e ressemeadura natural), que poderão formar o banco de sementes do solo. Os ensaios foram realizados no município de Jari - RS, em uma área cultivada sob o sistema de "plantio direto". Foram coletadas 50 amostras em cada sistema de manejo, com um espaçamento de 10x20m, utilizando um amostrador de diâmetro de 0,05m e uma profundidade de 0,1m. O levantamento do número de sementes e da emergência das plântulas foi realizado no Laboratório Didático da Faculdade de Agronomia Eliseu Maciel (UFPel)....

Barbadocladius Cranston &amp;amp; Krosch, a new genus of Orthocladiinae (Diptera: Chironomidae) from South America
Provedor de dados: 82
Autores: Cranston,PS; Krosch,M.
Barbadocladius n. gen. is erected and described in larval, pupal and adult stages for two species: B. andinus sp. nov. and B. limay sp. nov., from Andean streams. The larva is distinctive by virtue of the very large ventromental 'beard' and the anterior parapods with a 'sleeve' of hooklets in addition to apical pectinate claws. The pupa has hooklets on some tergal and sternal intersegmental membranes. The adult, reported only in teneral specimens has hairy eyes, no antennal apical strong seta, no acrostichals, bare and unmarked wings, cylindrical 4th tarsomere subequal in length to the 5th, pulvilli about half the claw length, and hypopygium with anal point, lacking a virga. Molecular phylogenetic analysis eliminates relationships directly to the...

Bargaining Power in Relational Contracts: An Experimental Study
Provedor de dados: 31
Autores: Cordero Salas,   Paula.
This paper provides experimental evidence of the economic impact from shifting bargaining power in relational contracts. I implement an experimental design that adjusts the bargaining power of sellers (agents) and the enforceability of the contract. I find that the vast majority of contracts take the form of efficiency wage contracts instead of contingent performance contracts when enforcement is partially incomplete and sellers have more bargaining power than buyers. The total contracted and actual compensation increase with the bargaining power of the sellers. However, sellers' profits are found to increase only if a part of the total payment is third-party enforceable. In this case, observed surplus and efficiency are lower than predictions. When no...

BARRERAS E INCENTIVOS ECONÓMICOS PARA LA RESTAURACIÓN DE LA BIODIVERSIDAD
Provedor de dados: 37
Autores: GARCÍA-FRAPOLLI,EDUARDO; LINDIGCISNEROS,ROBERTO.
Uno de los aspectos fundamentales y menos considerados desde un punto de vista formal, es el de los costos asociados a la restauración ecológica y de los incentivos económicos para llevarla a cabo. A través del análisis de ensayos de restauración con una comunidad indígena en el occidente de México se analizan los aspectos económicos relacionados con proyectos de restauración concretos y con el contexto económico que incentiva la restauración ecológica. Concluimos que, mientras que la relación costo-beneficio del trabajo directamente relacionado con el proceso de restauración puede ser calculado de manera directa en algunos casos, los beneficios asociados a recuperar la diversidad de los ecosistemas restaurados representan mayor dificultad. En cuanto a los...

Barriers in the pelagic: population structuring of Calanus helgolandicus and C. euxinus in European waters
Provedor de dados: 16
Autores: Yebra, L.; Bonnet, D.; Harris, R.P.; Lindeque, P.K.; Peijnenburg, K.T.C.A.
Molecular studies of marine plankton have shown that ecological and/or environmental barriers play an important role in separating populations. Calanoid copepods are central in marine ecosystems, and dramatic biogeographical shifts in copepod assemblages associated with recent climate warming have been reported. We examined spatial population structuring in European waters of the Atlantic Ocean and Mediterranean Sea of Calanus helgolandicus and its sister species, C. euxi nus, from the Black Sea based on genetic and morphometric characters. The aims were to identify barriers to dispersal, relate these to hydrographic characteristics and infer historical patterns of distribution and demography. We analysed a 408 bp fragment of the mitochondrial 16S gene...

Basal defoliation and their influence in agronomic and phytopathological traits in tomato plants
Provedor de dados: 75
Autores: Silva,Laércio J da; Milagres,Carla do C; Silva,Derly José H da; Nick,Carlos; Castro,João Paulo A de.
The incidence of leaf diseases is one of the main factors limiting the tomato crop production, increasing the production cost due to excessive pesticide application. The basal leaf removal could reduce inoculum sources, disease severity and contribute to reducing the use of pesticide. Aiming to evaluate the efficiency of this practice on the reduction of tomato leaf diseases and the effect in the quality and in the productivity of the tomato plants for in natura consumption, two experiments were carried out to test four levels of basal leaf removal. Basal leaves removal, at fruit harvesting, is efficient in reducing the infected plant area by disease, what can mean smaller disease severity and least inoculum source in the field. Also, the all basal leaf...

Base temperature for leaf appearance and phyllochron of selected strawberry cultivars in a subtropical environment
Provedor de dados: 53
Autores: Rosa,Hamilton Telles; Walter,Lidiane Cristine; Streck,Nereu Augusto; Andriolo,Jerônimo Luiz; Silva,Michel Rocha da; Langner,Josana Andréia.
Leaf development is characterized by the appearance of new leaves and is related to crop leaf area index, which affects the interception of solar radiation used for photosynthesis and biomass production and ultimately defines crop yield. The objectives of this paper were to estimate the base temperature for leaf appearance and to determine the phyllochron of two strawberry cultivars considering several planting dates. A two-year field experiment was conducted during 2008 and 2009 in Santa Maria (RS). The cultivars Arazá (early) and Yvapitá (late) were used at three planting dates in both years. Base temperature (Tb) was estimated using the Mean Square Error (MSE) approach of the regression between accumulated leaf number (LN) and accumulated thermal time...

Bat assemblage in savanna remnants of Sonora, central-western Brazil
Provedor de dados: 49
Autores: Cunha,Nicolay Leme da; Fischer,Erich; Santos,Carolina Ferreira.
The Cerrado (savanna) is a wide Neotropical formation, but the knowledge on the occurrence and distribution of bat species for this phytogeographic region is scarce, especially in the western portion. Here we address what are the bat species and their relative abundances in a western Cerrado site, municipality of Sonora, Mato Grosso do Sul, Brazil. Bats were mist-netted in eight non consecutive months over the course of two years. Sampled bats (n = 507) belonged to 18 species. The estimator Jackknife 1 estimated 22 species, and diversity (H') was 1.6. Richness and diversity of bats in Sonora were slightly higher than in the southern Cerrado, and similar to or lower than in the central Cerrado. Frugivorous species predominated, as expected, however richness...

Batch and fixed-bed column biosorption of manganese ion by Sargassum filipendula
Provedor de dados: 69
Autores: Henriques,Cristiane Assumpção; da Costa,Antonio Carlos Augusto; dos Reis,Marcelo Martins; Costa,André Luiz Hemerly; Luna,Aderval Severino.
This paper presents experimental data of the biosorption of manganese onto Sargassum filipendula in both batch and fixed-bed column systems. Batch equilibrium data were used for nonlinear fittings of the Langmuir and Freundlich isotherms. A mathematical model based on mass balances in the fluid and in the sorbent was applied to represent the experimental fixed-bed column data. The utilization of isotherm parameters from the batch experiments in the breakthrough model implied a significant mismatch in relation to the laboratory data. Alternatively, additional fixed-bed column data provided new parameters for the isotherm evaluation, and the corresponding simulated profile of the breakthrough curve reached better agreement to the experimental results.

The animal breeding values forecasting at futures times is a relevant technological innovation in the field of Animal Science, since its enables a previous indication of animals that will be either kept by the producer for breeding purposes or discarded. This study discusses an MCMC Bayesian methodology applied to panel data in a time series context. We consider Bayesian analysis of an autoregressive, AR(p), panel data model of order p, using an exact likelihood function, comparative analysis of prior distributions and predictive distributions of future observations. The methodology was tested by a simulation study using three priors: hierarchical Multivariate Normal-Inverse Gamma (model 1), independent Multivariate Student's t Inverse Gamma (model 2) and...

Bayesian estimation of non-stationary Markov models combining micro and macro data
Provedor de dados: 31
Autores: Storm,   Hugo; Heckelei,   Thomas.
In this poster a Bayesian estimation framework for a non-stationary Markov model is developed for situations where sample data with observed transition between classes (micro data) and aggregate population shares (macro data) are available. Posterior distributions on transition probabilities are derived based on a micro based prior and a macro based Likelihood function thereby consistently combining previously separated approaches. Monte Carlo simulations for ordered and unordered Markov states show how observed micro transitions improve precision of posterior knowledge as the sample size increases.

The objective of this study was to estimate genetic parameters for survival and weight of Nile tilapia (Oreochromis niloticus), farmed in cages and ponds in Brazil, and to predict genetic gain under different scenarios. Survival was recorded as a binary response (dead or alive), during harvest time in the 2008 grow-out period. Genetic parameters were estimated using a Bayesian mixed linear-threshold animal model via Gibbs sampling. The breeding population consisted of 2,912 individual fish, which were analyzed together with the pedigree of 5,394 fish. The heritabilities estimates, with 95% posterior credible intervals, for tagging weight, harvest weight and survival were 0.17 (0.09-0.27), 0.21 (0.12-0.32) and 0.32 (0.22-0.44), respectively. Credible...

Autores: Movahedi,Zahra; Norouzi,Sayna; Mamishi,Setareh; Rezaei,Nima.
Bacillus Calmette Guerin (BCG) vaccine, which is administered to all newborns in some regions, could lead to serious complication ranging from local disease (known as BCGitis) to disseminated disease (BCGosis) in a group of patients with primary immunodeficiency diseases. We are reporting here a 3.5 year-old girl with a history of prolonged BCGitis, which developed to disseminated disease without any other special features. Immunological studies with nitro-blue tetrazolium test confirmed the diagnosis of chronic granulomatous disease in this patient. Chronic granulomatous disease should be considered in the list of differential diagnosis in all children with BCGosis, even in the absence of any other manifestations related to immunodeficiency.

Autores: Costa,Eula Maria de M. B; Pimenta,Fabiana Cristina; Luz,Christian; Oliveira,Valéria de; Oliveira,Marília; Bueno,Elda; Petrofeza,Silvana.
Beauveria bassiana genetic diversity and ability to synthesize quercetin 2,3-dioxygenase (quercetinase) were analyzed. B. bassiana isolates, obtained from Brazilian soil samples, produced quercetinase after induction using 0.5 g/L quercetin. B. bassiana ATCC 7159 (29.6 nmol/mL/min) and isolate IP 11 (27.5 nmol/ml/min) showed the best performances and IP 3a (9.5 nmol/mL/min) presented the lowest level of quercetinase activity in the culture supernatant. A high level of polymorphism was detected by random amplified polymorphic DNA (RAPD) analysis. The use of internal-transcribed-spacer ribosomal region restriction fragment length polymorphism (ITS-RFLP) did not reveal characteristic markers to differentiate isolates. However, the ITS1-5.8S-ITS2 region...

Bedbugs (Cimicidae infestation): the worldwide renaissance of an old partner of human kind
Provedor de dados: 55
Autores: Criado,Paulo Ricardo; Belda Junior,Walter; Criado,Roberta Fachini Jardim; Silva,Roberta Vasconcelos e; Vasconcellos,Cidia.
Bedbugs have been known as a human parasite for thousands of years, but scientific studies about this insect are recent and limited. Cimex lectularius, the common bedbug, was a well-known parasite in human dwellings until the end of the Second World War. Nowadays, bedbugs are considered uncommon in the industrialized world. Anecdotal reports suggest that bedbugs are getting more common in the United States, Canada, and United Kingdom. In Brazil, there are few reports about bedbug infestations in the literature. The aim of this article was to alert physicians, especially in Brazil, about this ectoparasitosis, including aspects of the bedbug biology, their parasitism in human host, treatment and prophylaxis.

Bedding choices for horses - an overview
Provedor de dados: 21
Autores: Saastamoinen, Markku.
Choose of the bedding material is important especially in the Northern climate conditions, because  the horses are kept most part of the day and year indoors during their life. Especially, the effect of  the bedding material on the quality of the stable air is of great importance. Based on their  properties, it seems that peat and straw pellets are the most suitable beddings for horse stables. Also  pelleted newspaper seems to have a good potential as a bedding material.

Autores: Oliveira,Ricardo Cardoso de; Barros,Sueli Teresa Davantel de.
The aims of the present work were to study the relationship between the fluxes, permeate quality, and fouling mechanism. A polysulfone membrane with 100 KDa and 0.12 m² of surface area was used. Permeate fluxes were measured for different pressures (0.5, 1.0, 1.5, and 2.0 bar) at the same temperature of 8 ºC. The fluxes measured for each pressure ranged from 22, 24, 27 and 30 kg h-1m-2 at 0.5, 1.0, 1.5 and 2.0 bar, respectively. Samples of the feed and permeate were analyzed for pH, color, turbidity, sugar, bitterness, and proteins. The fouling mechanisms observed were cake filtration, partial pore blocking, and complete pore blocking.

Bees as entomovectors and the biological control agent Gliocladium catenulatum J1446
Provedor de dados: 21
Autores: Muljar, Riin; Mänd, Marika.
There is a need for more environmentally friendly plant protection methods, since the increasing use of agrochemicals has led to pesticide residues and resistance problems in the control of Botryrtis cinerea. An alternative to chemical spraying is to use bees as entomovectors to disperse biological control agents. Prestop Mix is a biofungicide that contains spores of the parasitic fungus Gliocladium catenulatum J1446, which has been successfully used in the control of B. cinerea. In 2010 we conducted a field experiment to study the efficiency of using bees in dispersing G. catenulatum in Estonian conditions. The study was carried out in two strawberry plantations of Tartu County, strawberry varieties were `Sonata` and `Polka`. Honey bee hives were placed...

Begging test: uma avaliação da graduação da comunicação visual entre cães sem raça definida, cães de raça (Golden Retrievers) e humanos
Provedor de dados: 65
Autores: Martinez,Edilberto Nobrega; Boere,Vanner.
O begging test tem sido usado para testar a capacidade dos cães em interpretar a atenção humana. Pistas faciais, como o olhar e a posição da cabeça são os principais sinais na comunicação entre cães e humanos. Até o momento, a estrutura do begging test utilizado em pesquisas não permitiu verificar se há uma graduação na atenção. Desse modo, não é possível dizer se a cabeça e o olhar diretamente dirigidos (muita atenção) ao cão aumentam o desempenho em relação a somente a posição da cabeça, mas sem olhar diretamente (pouca atenção) ou cabeça plus olhar desviados (desatenção). Nesse sentido, um teste envolvendo 58 cães de raça pura (Golden Retrievers) e mista foi realizado, nas três condições de atenção, com homens e mulheres estranhos aos animais servindo...

Over the years, Salmonella Heidelberg (SH) has gained prominence in North America poultry production and in the poultry production of other countries. Salmonella Heidelberg has been isolated and reported from poultry and poultry products in Brazil since 1962, whereas Salmonella Enteritidis (SE) has only emerged as a serious problem in poultry and public health since 1993. These strains of Salmonella can cause intestinal problems in newly hatched chicks, and infection may persist until adulthood. Upon slaughter of chickens, Salmonella can contaminate carcasses, a condition that poses a threat to human health. The aim of this study was to compare the fecal excretion of Salmonella Enteritidis and Salmonella Heidelberg in newly hatched chicks (orally...

Autores: Matos-Moreira,Mariana; Niemeyer,Júlia Carina; Sousa,José Paulo; Cunha,Mário; Carral,Emilio.
The application of organic wastes to agricultural soils is not risk-free and can affect soil invertebrates. Ecotoxicological tests based on the behavioral avoidance of earthworms and springtails were performed to evaluate effects of different fertilization strategies on soil quality and habitat function for soil organisms. These tests were performed in soils treated with: i) slurry and chemical fertilizers, according to the conventional fertilization management of the region, ii) conventional fertilization + sludge and iii) unfertilized reference soil. Both fertilization strategies contributed to soil acidity mitigation and caused no increase in soil heavy metal content. Avoidance test results showed no negative effects of these strategies on soil...

Behavioral counter-strategies against infanticide in corn mouse females, Calomys musculinus
Provedor de dados: 81
Autores: Coda,José A.; Priotto,José W.; Steinmann,Andrea R.
Based on the hypothesis that in C. musculinus both female territorial behavior and promiscuity are counter-strategies against infanticide by females and males respectively, our objective was to test the following predictions: (1) mother aggression deters infanticide by females; (2) previous matings prevent infanticide by males. We conducted 116 behavioral encounters between mothers and intruders to study the nest related behaviors. Mother-pups units (Mu) were grouped in three treatments in relation to the intruder feature: 55 Mu were placed with siring males, 27 Mu and 34 Mu were housed with non-siring males and reproductively active females, respectively. We also calculated offspring survival rate for each treatment. The nest related behaviors varied...

Autores: Loiola,Geovanni Ribeiro; De Marco,Paulo.
Behavioral ecology of Heteragrion consors Hagen (Odonata: Megapodagrionidae): a shade-seek Atlantic forest damselfly. The intensity of the inter and intra-sexual selection can affect male behavioral traits as territorial fidelity and aggressiveness allowing the existence of different strategies. However, its differential success could be affected by environmental - as the diel variation in temperature - and physiological constrains - as the variation in thermoregulatory abilities. In this context, we present a behavioral analysis of Heteragrion consors (Zygoptera, Megapodagrionidae) trying to characterize its mating system, diel activity pattern, temporal budget, territoriality and reproductive biology. These data were obtained based on field observations...

The present work tested whether Triatoma pseudomaculata Corrêa &amp;amp; Espínola shows behavioral traits indicating that it is capable of feeding on arthropods. We consistently observed nymphs extending their proboscis in the direction of cockroaches and attempting to bite. Insects presented a preference for biting specific cockroach body parts. Our results suggest that arthropod hemolymph represents an alternative source of food that increases the survival of T. pseudomaculata individuals undergoing long starvation.

An approach combining laboratory experiments and numerical modelling was used to investigate the behaviour of a floc population during an idealized tidal cycle. The experiment was conducted on suspended sediments at a concentration of 93 mg l−1 collected in the field. It was based on a jar test device to reproduce tidal-induced turbulence and coupled with a CCD camera system and image post-processing software to monitor floc size distribution. At the same time, a 0D size-class based aggregation/fragmentation model (FLOCMOD) was developed to simulate changes in the floc population over the tidal cycle. Experimental results revealed strong variability of the behaviour of microfloc and macrofloc populations with respect to the varying shear rates observed in...

Behaviour of captive Ostrich chicks from 10 days to 5 months of age
Provedor de dados: 96
Autores: Amado,Marina Freire; Xavier,Diego Batista; Boere,Vanner; Torres-Pereira,Carla; McManus,Concepta; Bernal,Francisco Ernesto Moreno.
The behaviour of ostrich chicks bred in captivity was studied by using groups with 30 birds in five age groups: from 10 to 40 days of age; from 41 to 60 days of age; from 61 to 90 days of age; from 91 to 120 days of age and from 121 to 150 days of age. Six birds at each age were ringed around one of their feet and observed for four consecutive days for eight hours daily in three periods (in the morning, at noon and in the afternoon), following the "one-zero" method for sampling. The order for observation of behaviour of the six selected birds was performed randomly at every thirty minutes, totalling 16 periods or 80 minutes/bird/day. Fourteen types of behaviour were observed. There were differences among ages for behaviour like standing, walking, running,...

Engineered nano-sized Cu oxide particles are extensively used in diverse applications. Because aquatic environments are the ultimate "sink" for all contaminants, it is expected that nanoparticles (NP) will follow the same fate. In this study, two marine invertebrates Scrobicularia plana and Hediste diversicolor were chosen as ecotoxicological models. The aim was to evaluate behavioural (burrowing kinetics, feeding rate) and biochemical (biomarkers) responses of S. plana and H. diversicolor exposed in the laboratory to Cu (10 mu g L(-1)) added in natural seawater either in the form of engineered nanoparticles (NPs) of CuO or as dissolved Cu in 2% HNO(3). Exposure was characterized by considering (i) the physico-chemical fate of NP (ii) the fraction of...

Beheersing bonenvlieg
Provedor de dados: 21
Autores: van den Broek, Rob.
De bonenvlieg kan op biologische percelen grote schade aanrichten in gewassen als spinazie, pompoen en bonen. Kiemplanten lijden soms zo erg onder vraat, dat er opnieuw gezaaid moet worden. De bonenvlieg beschadigt zaden en/of wortels van vele soorten planten en gewassen. Vooral de eerste jaren na invoering van een teeltsysteem met niet-kerende grondbewerking lijken de kansen op  aantasting toe te nemen.  In dit rapport de onderzoeksresultaten naar beheersing van de bonenvlieg.

Beheersing valse meeldauw in de uienteelt
Provedor de dados: 21
Autores: Evenhuis, Bert.
Valse meeldauw (Peronospora destructor) in uien vormt een terugkerend probleem. Bij vroege aantasting en onvoldoende bestrijding leidt valse meeldauw tot nagenoeg volledig oogstverlies. In de praktijk komt het meestal niet zover, maar de schade kan toch aanzienlijk zijn. Biologische telers zijn voor de beheersing van valse meeldauw aangewezen op preventie. Alle maatregelen die primaire bronnen aanpakken resulteren in een latere start van de epidemie en geven het gewas een langere groeiperiode.    In dit rapport de onderzoeksresultaten naar beheersing van valse meeldauw in de uienteelt; warmwaterbehandelingen, afdekken van afvalhopen en branden van besmette percelen. En tips om aantasting door valse meeldauw te voorkomen.

Beheersing Wortelvlieg
Provedor de dados: 21
Autores: van den Broek, Rob; van Roozen, Klaas.
De larve van de wortelvlieg, Psila rosae, kan in een aantal schermbloemige gewassen grote schade veroorzaken. Het insect komt met name in de gematigde streken van het noordelijk halfrond voor, maar ook in sommige subtropische  streken. Overal in Nederland waar peen wordt geteeld, komt aantasting voor. In Nederland lijken de biologische telers goed met het probleem wortelvlieg om te gaan; het aantal meldingen van schade en afkeuring valt mee. Met slimme  teeltmaatregelen zijn de problemen beheersbaar en dankzij inzicht in de biologie en levenscyclus van de wortelvlieg kunnen passende maatregelen de schade beperken. In dit BioKennisbericht een overzicht en tips.

Autores: Meyling, Nicolai V.; Thorup-Kristensen, Kristian; Eilenberg, Jørgen.
The below- and aboveground communities of fungal  entomopathogens (Ascomycota: Hypocreales) were investigated in an experimental conventional and organic vegetable cropping system over two seasons in Denmark. The experimental design allowed for evaluating differences between farming practices in the occurrence of soil-borne fungal entomopathogens and as natural infections aboveground in arthropod hosts. Belowground, Metarhizium anisopliae dominated the agricultural field with Beauveria bassiana, Metarhizium flavoviride and Isaria fumosorosea being present at lower frequencies. Abundances of M. anisopliae were not different between conventional and organic soils. Aboveground, B. bassiana was the most common fungal entomopathogen in arthropod host cadavers....

Benchmarking the SPARC software program for estimating solubilities of naphthalene and anthracene in organic solvents
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
The SPARC software program was benchmarked for calculating the solubilities of two representative polyaromatic hydrocarbons (PAHs), naphthalene and anthracene, in a range of organic solvents at various temperatures. Although SPARC was able to reasonably approximate the solubilities of naphthalene in some organic solvents, gross errors were obtained for other solvents. For anthracene, poor prediction performance was observed in all solvents considered. Overall, the results suggest that SPARC is currently not suitable for accurately predicting the solubilities of representative PAHs relevant for the petroleum sector in various organic solvents.

Provedor de dados: 31
Autores: Asaduzzaman,   Md; Naseem,   Anwar; Singla,   Rohit.
Homestead vegetable gardening can play a significant role in improving food security for the resource poor rural households in developing country like Bangladesh. The present study quantifies costs/benefits of traditional and developed homestead vegetable production systems, and analyzes the underlying factors contributing to food security. The result suggests that developed gardening has better performances in terms of calorie intake and economic performances over traditional but the optimal calorie intake with least-cost technology could be a feasible livelihood strategy for resource poor people. The result also suggests that education, sex, and garden area have significant effect on food security. The occupation and family size are also positively...

The aim of this paper was to evaluate the automated acclimatization effects during pre-milking of cows on thermal conditioning, physiology, milk production and cost-benefit of the automated adiabatic evaporative cooling system (AECS). The treatments 20; 30; 40 min and control consisted of exposure time of pre-milking cows to the automated AECS. Sixteen cows were used with an average daily milk yield of 19 kg, distributed in a 4 x 4 Latin square design. The Tukey's test (P&lt;0.05) was used to compare the means. The environmental variables, dry bulb temperature (DBT, ºC) and relative humidity (RH, %), were recorded every minute, which allowed the determination of the system efficiency through the Temperature and Humidity Index (THI). The respiratory rate...

Autores: Herd,   Robert M.; Arthur,   Paul F.; Dibley,   K.; Mula,   D.; Snelgar,   T.; Thompson,   J.
This experiment investigated the benefits of feeding steers bred from parents known to be of high genetic merit for feed efficiency (HE; midparent net feed intake-estimated breeding value (NFI-EBV) ≤-0.3kg/day), medium efficiency (ME: midparent NFI-EBV &gt;-0.3 to 0.14 kg/day), or low efficiency (LE; midparent NFI-EBV ≥0.16kg/day). The steers were evaluated over a 251-day feeding period in a large commercial feedlot. Genetic superiority in NFI had a favourable impact on the commercial performance of Angus steers by reducing feed consumed with no adverse effect on final turnoff weight. Each HE steer consumed on average 2.60t of feed compared to 2.87t by the ME and LE steers, with no compromise in weight gain. The HE steers gained less subcutaneous ribfat...

Presently the value of the organic food market in Germany is approximately 5.8 billion Euros and is growing, but this growth is not reflected in the number of organic farmers. In order to raise the number of organic farmers, organic extension plays an important role. The extension system of organic farming is partly linked to the conventional system; for example organic extensionists are employed by the Chamber of Agriculture. In addition to this, a separate organic extension system exists, organized by the organic farm associations. The key questions of the study are: how to reach conventional apprentices and farmers from the organic-extension point of view, and how to enhance their decision-making authority in terms of conversion. The overall goal is...

Berberine, an isoquinoline alkaloid derived from plants, is a traditional medicine for treating bacterial diarrhea and intestinal parasite infections. Although berberine has recently been shown to suppress growth of several tumor cell lines, information regarding the effect of berberine on colon tumor growth is limited. Here, we investigated the mechanisms underlying the effects of berberine on regulating the fate of colon tumor cells, specifically the immorto Min mouse colonic epithelial (IMCE) cells carrying the Apcmin mutation, and of normal colon epithelial cells, namely young adult mouse colon (YAMC) epithelial cells. Berberine decreased colon tumor colony formation in agar, and induced cell death and LDH release in a time- and concentration-dependent...

Beregninger av nitrogenbalansen på 50 gårdsbruk i kommunene Midsund, Fræna, Gjemnes, Surnadal og Rindal
Provedor de dados: 21
Autores: Lyche, Arnar.
Landbruk Nordvest har gjennomført nitrogenbalanse-beregninger på 50 gårdsbruk ikommunene Midsund, Fræna, Gjemnes, Surnadal og Rindal. Dette er et ledd i ”klima-arbeidet” i de fem kommunene. På samtlige melke-produksjonsbruk i undersøkelsen ble det kjøpt inn langt mer nitrogen og fosfor enn hva som ble solgt ut igjen, slik at gårdene tilførte flere næringsstoffer enn hva de fjernet. Det er en betydelig variasjon mellom enkeltbruk. Nitrogen-balanseberegningene for de 4 sauebrukene med økologisk drift viser at det også her er overskudd på nitrogen.

Die Nachfrage nach Bio-Produkten wächst während die Erzeugung tendenziell stagniert. Das gilt für Hamburg, wie auch bundesweit. Um jedoch Entscheidungen zu gezielten Maßnahmen für die Stärkung eines regionalen Öko-Marktes zu treffen, werden Informationen über den Markt und seine Strukturen benötigt, die bislang in Hamburg fehlen.   Die vorliegende Studie der Universität Hamburg untersuchte daher im Auftrag der Behörde für Wirtschaft und Arbeit der Freien und Hansestadt Hamburg die aktuellen Angebots- und Vermarktungsstrukturen von Bio-Produkten in und um Hamburg. Ziel war es zunächst, eine Bestandsaufnahme der Hamburger Öko-Marktstrukturen vorzunehmen und ein Bild darüber zu zeichnen, welche Rolle die regionalen Bezugs- und Absatzwege in Hamburg spielen....

Autores: Tichter, Arne; Sweers , Weert; Müller, Jürgen; Dittmann, Lisa; Brinkmann, Jan; March, Solveig; Isselstein, Johannes.
Die Erzeugung hochwertiger Grobfuttermittel spielt für die Rentabilität und Nachhaltigkeit der Milcherzeugung im ökologischen Landbau eine entscheidende Rolle. Grobfuttermittel beeinflussen die Gesundheit und Leistung des Milchviehs auf verschiedene Art und Weise. Zudem variieren die standörtlichen Bedingungen des Futterbaus sowie die avisierten Leistungsniveaus der Milchviehhaltung in der Praxis erheblich (Haas et al. 2001, Brinkmann &amp; Winckler 2005, Müller-Lindenlauf et al. 2010). Ziel dieser Untersuchung ist es, die Variabilität der betrieblichen Konzepte der Grobfuttererzeugung überregional zu analysieren und etwaige Strategietypen zu identifizieren, die für weitergehende Analysen und Beratungsempfehlungen eine objektivierte Grundlage bieten.

This paper aims to present the results of an expert and stakeholder based Delphi approach for analysing the performance of Swiss organic agriculture in terms of sustainability. We analysed four different production systems: Bio Suisse standards, public organic standards, integrated farming and farming according to Swiss cross compliance standards. The study illustrated that none of the farming systems performs 100% sustainable against any of the indicators. However, organic production showed an about 1-20% better performance than conventional and integrated systems. Particularly high scores were achieved for product quality, animal welfare, and biodiversity, while performing below average regarding resource use, food security and climate change. We...

Bias Correction in Logarithmic Regression and Comparison with Weighted Regression for Nonlinear Models
Provedor de dados: 17
Autores: Wei Sheng Zeng; Shou Zheng Tang.
Non-linear models with heteroscedasticity are commonly used in ecological and forestry modeling, and logarithmic regression and weighted regression are usually employed to estimate the parameters. Using the single-tree biomass data of three large samples, the bias correction in logarithmic regression for non-linear models was studied and comparison between logarithmic regression and weighted regression was discussed in this paper. Firstly, the imminent cause producing bias in logarithmic regression was analyzed, and a new correction factor was presented with which three commonly used bias correction factors were examined together, and the results showed that the correction factors presented here and derived by Baskerville (1972) should be recommended,...

Biceps Brachii Muscle Innervation Zone Location in Healthy Subjects Using High-Density Surface Electromyography
Provedor de dados: 77
Autores: Guzmán,Rodrigo A; Silvestre,Rony A; Arriagada,David A.
Among the sequelae of central nervous system injury is spasticity which is difficult to manage in rehabilitation. Current treatments consider the administration of the botulinum toxin. However, results have proved highly variable in terms of effectiveness, attributable to the distance between the injection site and the innervations-zone (IZ). High Density sEMG (HDsEMG) has been used to gather information about muscle physiology and for location of the IZ. The aim of this study was to characterize the IZ of the biceps brachii muscle in healthy subjects during isometric contraction. We assessed the biceps brachii muscle of twenty healthy subjects (n=20) using a 64 surface electrodes matrix. The average location of the IZ was 34% distal to the line between...

Bidding behavior in environmental contract auctions with incomplete monitoring
Provedor de dados: 31
Autores: Romstad,   Eirik; Alfnes,   Frode.
It is well known from the compliance literature that whenever it costly to monitor agents' compliance to contract terms, compliance is likely to be incomplete. This paper goes one step further by examining the implications of incomplete monitoring on agent's sales offers in auctions for environmental contracts. From a monitoring perspective we show allocation contracts to least cost also produces another gain – that less resources need to be spend on monitoring and enforcement. To get full use of this insight one needs to have auction procedures that provide incentives for truthful revelation of agents' private alternate incomes. Our second result is that the incentives for truthful revelation is lost when monitoring is incomplete unless the expected value...

Bidding for WIC infant formula contracts: Do non-WIC customers subsidize WIC customers?
Provedor de dados: 31
Autores: Davis,   David E.
Although the WIC food assistance program purchases over one-half of all US infant formula, I find the program has little impact on the prices paid by non-WIC customers. I estimate infant-formula marginal cost and find that it is low compared to price, implying large price-cost markups. But, the WIC program is not to blame. Instead large price-cost markups are likely due to customer’s price insensitivity. WIC’s impact on non-WIC customers comes through an increase in sales owing to a WIC “spill-over” effect. The WIC approved brand attains a prominence in the market that makes it a natural choice for non-WIC customers, which makes attaining WIC approval valuable to firms. Firms bid with rebates to attain exclusive WIC approved status which results in...

Bienestar animal en la enseñanza de Medicina Veterinaria y Zootecnia: ¿Por qué y para qué?
Provedor de dados: 108
Autores: Aluja,Aline S. de.
Se revisan brevemente las razones del porqué el Bienestar animal actualmente es considerado una ciencia que debe ser incluida en el plan de estudios de las escuelas y facultades de Medicina Veterinaria y Zootecnia. Se menciona que los conocimientos actuales sobre anatomía, fisiología, neurobiología y otros, nos comprueban que el organismo animal y en especial su sistema nervioso central (SNC) tienen muchas similitudes con los del ser humano y que los estudios observacionales y de comportamiento animal demuestran que los animales se dan cuenta, sufren ansiedad, miedo, estrés y dolor. Se subraya la relación que tiene el bienestar de los animales con la producción y se concluye que es necesario que los médicos veterinarios y zootecnistas conozcan el...

Bifocal Distraction in Patient with Rheumatoid Arthritis and Severe Condylar Degeneration: Report of Case
Provedor de dados: 77
Autores: Chaves Neto,Henrique Duque de Miranda; Olate,Sergio; Mazzonetto,Renato; Spagnoli,Daniel B.
Facial involvement in patients with rheumatoid arthritis is variable depending on the type, onset, and duration of the disease. The treatment of patients with open bite resulting from degenerative changes on the condyles can be a challenge for the surgeon. Rheumatoid arthritis is a systemic disorder of unknown etiology characterized by chronic inflammation and proliferation of synovial tissue. Studies showed that patients with rheumatoid arthritis can developed progressive osteoarthrosis that result in gross radiographic changes in the condyles. With the development of distraction osteogénesis for treatment of mandible hypoplasia a new chapter has been opened in the surgical management of patients with rheumatoid arthritis associated with skeletal...

Big Defensins, a Diverse Family of Antimicrobial Peptides That Follows Different Patterns of Expression in Hemocytes of the Oyster Crassostrea gigas
Provedor de dados: 5
Autores: Rosa, Rafael D.; Santini, Adrien; Fievet, Julie; Bulet, Philippe; Destoumieux-garzon, Delphine; Bachere, Evelyne.
Background: Big defensin is an antimicrobial peptide composed of a highly hydrophobic N-terminal region and a cationic C-terminal region containing six cysteine residues involved in three internal disulfide bridges. While big defensin sequences have been reported in various mollusk species, few studies have been devoted to their sequence diversity, gene organization and their expression in response to microbial infections. Findings: Using the high-throughput Digital Gene Expression approach, we have identified in Crassostrea gigas oysters several sequences coding for big defensins induced in response to a Vibrio infection. We showed that the oyster big defensin family is composed of three members (named Cg-BigDef1, Cg-BigDef2 and Cg-BigDef3) that are...

Bigger is Better: Avoided Deforestation Offsets in the Face of Adverse Selection
Provedor de dados: 31
Autores: van Benthem,   Arthur A.; Kerr,   Suzi.
Voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines and participants will self-select into the program, adverse selection will reduce efficiency and possibly environmental integrity. In contrast, pure subsidies lead to full participation but require large financial transfers. We present a simple model to analyze this trade-off between adverse selection and infra-marginal transfers. We find that increasing the scale of voluntary programs both improves efficiency and reduces transfers. We show that discounting (paying less than full value for offsets) is inefficient and cannot be used to reduce the fraction of offsets that are...

Bilateralism in Agriculture when Countries use Distorting Domestic Policies
Provedor de dados: 31
Autores: May,   Daniel E.
A recent theoretical research proved that countries always have an incentive to deviate from global free trade when international markets are oligopolistic and when governments are politically biased. This result suggests that global free trade in agriculture (GFTA) cannot be reached as political bias and market power have both been identified. According to May (2011), bilateral agreements could eventually be used as alternative political tools to reach GFTA. This article extends the work of this author to determine whether bilateralism could also lead to GFTA in a realistic world where governments use distorting domestic policies to protect their agricultural sector.

Bioactive compounds and antioxidant capacities in the flavedo tissue of two citrus cultivars under low temperature
Provedor de dados: 61
Autores: Mohammadian,Mansour Afshar; Mobrami,Zeinab; Sajedi,Reza Hasan.
Antioxidants production is amongst the physiological responses of plants to protect their tissues from oxidative damages caused by chilling and freezing stresses. Indeed, cold tolerance of plants is related to production of reactive oxygen species (ROS) scavengers to combat oxidative stress. In this study, two citrus cultivars including Citrus sinensis 'Siavaraz' and Citrus limon 'Lisbon' grown at the north of Iran were examined to compare antioxidants changes including total flavonoid, total phenol and total antioxidant capacities (TAC) in the flavedo tissue of the fruits under various low temperature treatments of control (15 ºC), 3, 0, -3 and -6 ºC. The results indicated that total flavonoid content and TAC in Citrus limon 'Lisbon' was significantly...

Chemical control is the main method for controlling the tomato leafminer, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae). Reported techniques for the evaluation of insecticide toxicity to the tomato leafminer are not in agreement with field conditions and do not allow us to verify whether doses used in the field are efficient for control. Thus, the objective of this work was to develop a bioassay methodology to study the toxicity of insecticide formulations to T. absoluta that represent field conditions for fast-acting insecticides (neurotoxics and inhibitors of respiration) and slow-acting insecticides (Bacillus thuringiensis and insect growth regulators). The leaf-dip method was the most efficient method for toxicity studies of insecticides...

Autores: Bourgeault, Adeline; Gourlay-france, Catherine; Priadi, Cindy; Ayrault, Sophie; Tusseau-vuillemin, Marie-helene.
This study investigates the ability of the biodynamic model to predict the trophic bioaccumulation of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni) and zinc (Zn) in a freshwater bivalve. Zebra mussels were transplanted to three sites along the Seine River (France) and collected monthly for 11 months. Measurements of the metal body burdens in mussels were compared with the predictions from the biodynamic model. The exchangeable fraction of metal particles did not account for the bioavailability of particulate metals, since it did not capture the differences between sites. The assimilation efficiency (AE) parameter is necessary to take into account biotic factors influencing particulate metal bioavailability. The biodynamic model, applied with AEs...

Autores: Ippolito, J.A.; Lentz, R.D.; Novak M, J; Spokas, K.A.; Collins, H.P.; Streubel, J.
Soil fertility benefits of charcoal application have been reported as early as 1847 indicating that plant nutrients are sorbed within charcoal pores.  The use of biomass-derived black carbon or biochar, the solid byproduct from the pyrolysis processing of any organic feedstock, has garnered recent attention as a potential vehicle for carbon sequestration and a beneficial soil conditioner.  However, most of the past biochar research has focused on improving the physico-chemical properties of tropical (i.e. terra preta) and highly weathered soils, while little research has focused on improving arid or semi-arid soils of the USA.  Here, we present an overview of the potential benefits and drawbacks of biochar usage in western US agro-ecosystems based on...

Excessive copper concentrations in water systems can negatively impact biological systems.  Because copper can form strong associations with organic functional groups, we examined the ability of biochar (a carbon-enriched organic bioenergy by-product) to sorb copper from solution.  In a batch experiment, potassium hydroxide-steam activated pecan shell biochar was shaken for 24 hours in pH 6, 7, 8, or 9 buffered solutions containing various copper concentrations to identify effect of pH on biochar copper sorption.  Afterwards, all biochar solids from the 24 hours shaking period were air-dried and then analyzed using X-ray absorption fine structure spectroscopy to determine solid-phase copper speciation.  In a separate batch experiment, biochar was shaken...

Gyroxin, a thrombin-like enzyme isolated from Crotalus durissus terrificus venom and capable of converting fibrinogen into fibrin, presents coagulant and neurotoxic activities. The aim of the present study was to evaluate such coagulant and toxic properties. Gyroxin was isolated using only two chromatographic steps - namely gel filtration (Sephadex G-75) and affinity (Benzamidine Sepharose 6B) - resulting in a sample of high purity, as evaluated by RP-HPLC C2/C18 and electrophoretic analysis that showed a molecular mass of 30 kDa. Gyroxin hydrolyzed specific chromogenic substrates, which caused it to be classified as a serine proteinase and thrombin-like enzyme. It was stable from pH 5.5 to 8.5 and inhibited by Mn²+, Cu²+, PMSF and benzamidine. Human...

Provedor de dados: 74
Autores: Garcia,Daniel Fantozzi; Oliveira,Ticiano G.; Molfetta,Greice A.; Garcia,Luiz V.; Ferreira,Cristiane A.; Marques,Adriana A.; Silva Jr.,Wilson Araujo.
Butyrylcholinesterase (BChE) is a plasma enzyme that catalyzes the hydrolysis of choline esters, including the muscle-relaxant succinylcholine and mivacurium. Patients who present sustained neuromuscular blockade after using succinylcholine usually carry BChE variants with reduced enzyme activity or an acquired BChE deficiency. We report here the molecular basis of the BCHE gene underlying the slow catabolism of succinylcholine in a patient who underwent endoscopic nasal surgery. We measured the enzyme activity of BChE and extracted genomic DNA in order to study the promoter region and all exons of the BCHE gene of the patient, her parents and siblings. PCR products were sequenced and compared with reference sequences from GenBank. We detected that the...

The effects of sublethal concentrations of cadmium (0.64 µg/L), iron (0.043 mg/L) and zinc (0.31 mg/L) and a mixture of these metals on succinate dehydrogenase (SD) and alkaline phosphatase (AP) activity and on structural changes in the mitochondria of epithelium cells of the digestive tract were examined in the oligochaete Limnodrillus hoffmeisteri after 96 h of exposure in artificial sediments. SD activity was significantly inhibited, particularly in treatments with Cd alone (92.57%), while AP increased its activity with Cd alone (73.23%). However, when this metal was mixed with Fe and Zn, the inhibition of SD activity was lower (67.82%) than with Cd alone, showing an antagonistic effect and AP increased its activity (73.26%). Mitochondria were...

Autores: Queiroz,Rafaela Josemara Barbosa; Santos,Durvalina Maria Mathias dos; Ferraudo,Antonio Sergio; Carlin,Samira Domingues; Silva,Marcelo de Almeida.
For sugarcane (Saccharum spp.) crops, the effects of an environmental stress, especially water deficiency, may cause severe productivity reduction, inferring negatively in the sugarcane industry. The tolerance of two sugarcane cultivars to a lack of water was made by analyzing the levels of the osmoprotectors, trehalose and free proline, and the biometrical variables of their initial growth. Biochemical and physiological responses of the cultivars, when subjected to water stress, were assayed to determine how these plants tolerate drought. The study was conducted in an acclimatized greenhouse (29.7 ± 4.3ºC and 75.0 ± 10.1% relative humidity) during 100 days and was divided into random blocks using a factorial 2 × 3 × 2 design (sugarcane cultivars × water...

Provedor de dados: 52
Autores: Slivinski,Christiane Trevisan; Machado,Alex Vinicius Lopes; Iulek,Jorge; Ayub,Ricardo Antônio; Almeida,Mareci Mendes de.
In this work, glucoamylase was produced by Aspergillus niger in solid-state fermentation. The enzyme was partially purified by ammonium sulphate precipitation and ion exchange and gel filtration chromatographies. Its molecular mass was estimated as 118.17 kDa by electrophoresis. The partially purified enzyme had an optimum pH range of 4.5-5.0 and an optimum temperature of 60 °C, with average activity 152.85 U mL-1. Thermal and pH stability assays with the crude extract showed that more than 60 % of the activity remained at pH 4.6 and 60 °C, even after an exposition to these conditions longer than 24 h. Yet, after purification, the enzyme was stable at these for at least 4 h, which indicated that its purification for use in starch saccharification was...

Biochemical Trade-Offs: Evidence for Ecologically Linked Secondary Metabolism of the Sponge Oscarella balibaloi
Provedor de dados: 5
Autores: Ivanisevic, Julijana; Thomas, Olivier P.; Pedel, Laura; Penez, Nicolas; Ereskovsky, Alexander V.; Culioli, Gerald; Perez, Thierry.
Secondary metabolite production is assumed to be costly and therefore the resource allocation to their production should be optimized with respect to primary biological functions such as growth or reproduction. Sponges are known to produce a great diversity of secondary metabolites with powerful biological activities that may explain their domination in some hard substrate communities both in terms of diversity and biomass. Oscarella balibaloi (Homoscleromorpha) is a recently described, highly dynamic species, which often overgrows other sessile marine invertebrates. Bioactivity measurements (standardized Microtox assay) and metabolic fingerprints were used as indicators of the baseline variations of the O. balibaloi secondary metabolism, and related to...

Provedor de dados: 58
Autores: Tavassoli,Mosa; Pourseyed,Seyed Hassan; Ownagh,Abdulghaffar; Bernousi,Iraj; Mardani,Karim.
The pigeon tick Argas reflexus is a pathogen-transmitting soft tick that typically feeds on pigeons, but can also attack humans causing local and systemic reactions. Chemical control is made difficult due to environmental contamination and resistance development. As a result, there is much interest in increasing the role of other strategies like biological control. In this study, the efficacy of three strains (V245, 685 and 715C) of entomopathogenic fungus Metarhizium anisopliae for biological control of three life stages of pigeon tick A. reflexus including eggs, larvae, engorged and unfed adults was investigated under laboratory conditions. Five concentrations of different strains of M. anisopliae ranging from 10³ to 10(7) conidia/ml were used. All...

Biodegradability screening of soil amendments through coupling of wavelength-scanned cavity ring-down spectroscopy to multiple dynamic chambers
Provedor de dados: 21
Autores: Bai, Mo; Köstler, Martin; Kunstmann, Jürgen; Wilske, Burkhard; Gattinger, Andreas; Frede, Hans-Georg; Breuer, Lutz.
A system was developed for the automatic measurements of 13CO2 efflux to determine biodegradation of extra carbon amendments to soils. The system combines wavelength-scanned cavity ring down laser spectroscopy (WS-CRDS) with the open-dynamic chamber (ODC) method. The WS-CRDS instrument and a batch of 24 ODC are coupled via microprocessor-controlled valves. Determination of the biodegradation requires a known d13C value and the applied mass of the carbon compounds, and the biodegradation is calculated based on the 13CO2 mixing ratio (ppm) sampled from the headspace of the chambers. The WS-CRDS system provided accurate detection based on parallel samples of three standard gases (13CO2 of 2, 11 and 22 ppm) that were measured simultaneously by isotope ratio...

Autores: BORSATO, A. V.; FEIDEN, A.
Neste documento, trata-se a biodiversidade não apenas como uma coleção de componentes isolados em vários níveis, mas principalmente a maneira como eles estão organizados e como interagem, ou seja, as interações e processos que fazem os organismos, as populações e os ecossistemas preservarem sua estrutura e funcionarem em conjunto. Em sistemas complexos de produção agrícola (agroecossistemas) as plantas medicinais, aromáticas e condimentares podem desempenhar importantes funções no que se refere as práticas de manejo agronômico com base em princípios agroecológicos. Nestes agroecossistemas, o principal desafio é selecionar e manejar um conjunto relativamente restrito de espécies (nativas ou exóticas) para atender as funções chave que nos ecossistemas...

Biodynamic Agriculture: The Journey from Koberwitz to the World, 1924-1938
Provedor de dados: 21
Autores: Paull, John.
In the last year of his life, the Austrian philosopher Rudolf Steiner challenged the direction and practice of contemporary agriculture. This was an early response to the proliferation of chemical agriculture. Steiner laid the foundation for an alternative agriculture, one that would ‘heal the earth’, in the agriculture course, a series of eight lectures at Koberwitz (now Kobierzyce, Poland) in 1924. Steiner set in train a process that led to the development, articulation, and naming of biodynamic agriculture, culminating in the publication of 'Bio-Dynamic Farming and Gardening' by Ehrenfried Pfeiffer in 1938. Pfeiffer's book appeared in Dutch, English, French, German, and Italian, and fulfilled Steiner's injunction to bring his agricultural lecture course...

Autores: Menegassi,Sílvio Renato Oliveira; Barcellos,Júlio Otávio Jardim; Lampert,Vinícius do Nascimento; Borges,João Batista Souza; Peripolli,Vanessa.
It was evaluated the bioeconomic impact of the breeding soundness evaluation on beef cattle production in southern Brazil. Two similar production systems, with and without the use of breeding soundness evaluation, were compared during 4 years in the municipality of Júlio e Castilhos. The rate of unsound bulls in the first examination was 22.8%. By performing the examination, calf production increased by 31%, 13.8 calves/bull/year and 24 kg of calves/cow/year. The benefit/cost ratio on the investment with the breeding soundness evaluation was R$ 35.84. The breeding soundness evaluation improves bioeconomic aspects of beef cow-calf systems.

Bioethanol production by inherent enzymes from rye and  wheat with addition of organic farming cheese whey
Provedor de dados: 21
Autores: Kádár, Zsófia; Christensen, Anne Deen; Thomsen, Mette Hedegaard; Bjerre, Anne Belinda.
In organic farming, there is a strong effort to minimize  the share of non-renewable resources (e.g. fossil fuels) and use only (preferably on-farm produced) bio-based energy and renewable raw materials, with the aim of achieving sustainable production systems and to become self-sufficient in energy.   Throughout our studies, wheat and rye grain was used as raw material in bioethanol production with the purpose of producing in situ enzymes (during germination) for the hydrolysis of starch in the grains and compared with commercial amylase enzyme preparations. Whey permeate was incorporated into the grain in Simultaneous Saccharification and Fermentation (SSF) process to use a cheap nutrient and water source. The ethanol fermentations were completed by 190...

Biofilm formation for organic matter and sulphate removal in gas-lift reactors
Provedor de dados: 69
Autores: Pizarro,Carolina; Donoso-Bravo,Andrés; Jeison,David; Ruiz-Filippi,Gonzalo; Chamy,Rolando.
A start-up strategy was presented and evaluated to obtain a well-established biofilm in a gas lift-reactor capable both for the removal of organic matter and sulphate. Pumice stone was used as material support. The influence of shear forces, given by the biogas recirculation, the effect of the COD/SO4-2 ratio and the OLRs increase were evaluated on the reactor performance. From the first stages, cell colonization was observed along with the presence of extracellular polymeric substances. The COD and sulphate removal was over 70%, for all conditions. The increase of gas flow did not have an adverse effect on biofilm development even though there was some detachment. Specific methanogenic activity of the biofilm increased along the experiments. Operational...

Biofilm production using distinct media and antimicrobial susceptibility profile of Pseudomonas aeruginosa
Provedor de dados: 55
Autores: Perez,Leandro Reus Rodrigues; Barth,Afonso Luís.
Biofilm production is an important mechanism for bacterial survival and its occurrence together with antimicrobial resistance represents a challenge for clinical management. Here, we evaluated the ability for biofilm production among P. aeruginosa isolates from patients with or without cystic fibrosis (CF) using two distinct media, besides determining the antimicrobial susceptibility profile of these isolates for eight antimicrobial agents. The ability for biofilm production when TSB medium was used was higher than when used CF sputum media (p = 0.0198). However, P. aeruginosa isolates from CF have demonstrated similar performance for biofilm production, independently of the medium used. Besides, among the biofilm-producing isolates, those recovered from...

Bio-fortification and isotopic labelling of Se metabolites in onions and carrots following foliar application of Se and 77Se
Provedor de dados: 21
Autores: Kapolna, Emese; Laursen, Kristian Holst; Husted, Søren; Larsen, Erik H.
The aims were to bio-fortify onions by foliar application of selenium (Se) and to intrinsically label bioactive Se-metabolites in onion and carrot by enriched, stable77Se for use in human physiological studies. Onion bulbs and leaves were enriched in Se by repeated foliar spraying of 10 or 100 μg Se mL-1 solutions of sodium selenite (Se(IV)) or sodium selenate (Se(VI)). ICP-MS analysis of onion leaves and bulbs showed that the Se concentration was enhanced by up to a factor of approximately 50 and 200 in bulbs and leaves, respectively. HPLC-ICP-MS analysis of proteolytic plant extracts showed that foliar application of Se(IV) gave rise to bio-synthesis of a higher fraction of the desired organic Se species and was better tolerated by the plants than...

Biofuel Economics in a Setting of Multiple Objectives &amp; Unintended Consequences
Provedor de dados: 31
Autores: Jaeger,   William K.; Egelkraut,   Thorsten M.
This paper examines biofuels from an economic perspective and evaluates the merits of promoting biofuel production in the context of the policies’ multiple objectives, life-cycle implications, pecuniary externalities, and other unintended consequences. The policy goals most often cited are to reduce fossil fuel use and to lower greenhouse gas emissions. But the presence of multiple objectives and various indirect effects complicates normative evaluation. To address some of these complicating factors, we look at several combinations of policy alternatives that achieve the same set of incremental gains along the two primary targeted policy dimensions, making it possible to compare the costs and cost-effectiveness of each combination of policies. For example,...

Provedor de dados: 31
Autores: Baker,   Justin Scott; Murray,   Brian C.; McCarl,   Bruce A.
Biofuel expansion efforts and climate mitigation policy could fundamentally alter land management trends in U.S. agriculture and forestry (AF) by mandating biofuel feedstock production and providing incentives for greenhouse gas (GHG) emissions reduction and carbon sequestration from terrestrial sources. Research has shown that biofuel expansion can alter commodity markets, induce agricultural land expansion, and intensify production. Meanwhile, GHG mitigation efforts could limit agricultural expansion, reduce current cultivation, and lower management intensity by incentivizing GHG emissions reduction and carbon sequestration within AF. To date, little work has attempted to quantify biofuel and climate policy-induced shifts together along the extensive and...

Autores: Kádár, Zsófia; Christensen , Anne Deen; Oleskowicz-Popiel, Piotr; Heiske, Stefan; Thomsen , Mette Hedegaard; Schmidt, Jens Ejbye.
Organic agriculture is one sustainable alternative to avoid negative environmental effects often caused by conventional agriculture. The area for organic farming in Europe is increased rapidly in the last decades and Denmark is one of the top-ten countries in Europe as regards the organic share of the total cultivated area.  The production of bioenergy from local biological resources and the maintenance of soil fertility seem to have been opposing aims in organic agriculture. In organic farming, there is a strong effort to reduce the reliance on fossil fuels and decrease greenhouse gas emissions in organic agriculture.   Cheese whey is a by-product from the dairy industry, which has the highest market share of organic foods in Denmark. It generates...

Autores: Oleskowicz-Popiel, Piotr; Nielsen, Henrik Bangsø; Thomsen, Anne Belinda; Schmidt, Jens Ejbye.
The production of bioenergy in organic agriculture (OA) can reduce its dependency on fossil fuels and decrease greenhouse‐gases (GHG) emissions; consequently increasing the sustainability of organic farming. Different biomasses were characterized biologically and chemically for their biogas and bioethanol potential at organic farms in Denmark. Batch experiments indicated methane yield [GJ/ha]: 260.7 (fresh maize), 272.7 (maize silage), 127.1 (fresh rye), 169.7 (rye silage), 161.7 (dried rye), 110.5 (fresh clover), 117.8 (clover silage), 72.3 (dried clover), and 41.1 (dried vetch). Theoretical ethanol yield [GJ/ha] showed: 119.8 (fresh maize), 109.2 (maize silage), 36.9 (fresh rye), 39.9 (rye silage), 84.7 (dried rye), 28.9 (fresh clover), 24.4 (clover...

Autores: Reents, Hans Jürgen; Kimmelmann, Stefan; Kainz, Max; Hülsbergen, Kurt-Jürgen.
In 2004/05, a field experiment regarding the effect of crop rotations for biogas-production to yield and soil properties was established at the organic experimental station Viehhausen. The different aspect of energy and food production and soil protection of the 5 main crop rotations are explained. The wheat yield 2007-09 was affected by legume percentage in crop rotation, which means partly lower yields but higher protein. The biogas slurry manuring increases the protein content in general but better in rotations with legumes.

Autores: Almeida,Teodoro I. R; Calijuri,Maria do Carmo; Falco,Patrícia B; Casali,Simone P; Kupriyanova,Elena; Paranhos Filho,Antonio C; Sigolo,Joel B; Bertolo,Reginaldo A.
The Pantanal of Nhecolândia, the world's largest and most diversified field of tropical lakes, comprises approximately 10,000 lakes, which cover an area of 24,000 km² and vary greatly in salinity, pH, alkalinity, colour, physiography and biological activity. The hyposaline lakes have variable pHs, low alkalinity, macrophytes and low phytoplankton densities. The saline lakes have pHs above 9 or 10, high alkalinity, a high density of phytoplankton and sand beaches. The cause of the diversity of these lakes has been an open question, which we have addressed in our research. Here we propose a hybrid process, both geochemical and biological, as the main cause, including (1) a climate with an important water deficit and poverty in Ca2+ in both superficial and...

Biologia floral e polinização em girassol (Helianthus annuus L.) por abelhas  africanizadas
Provedor de dados: 22
Autores: Toledo, V. A. A.; Chambó, E. D.; Halk, A. L.; Faquinello, P.; Parpinelli, R. S.; Ostrowski, K. R.; Casagrande, A. P.B.; Ruvolo-takasusuki, M. C.C.
O girassol (Helianthus annuus  L.) é uma planta de polinização cruzada  e os seus principais polinizadores são as abelhas. Com a polinização por insetos o girassol produz sementes, sendo a abelha africanizada  Apis mellifera  L. o agente mais efetivo. A  performance desta abelha como polinizadora depende de vários fatores, sendo eles, a disponibilidade de pólen e néctar na flor, condições climáticas e aspectos físicos do solo. O girassol é pouco sensível às variações no fotoperíodo, fato este que permite seu escalonamento de produção em quase todo o território nacional. No Brasil uma grande parte do território é considerada apta para o cultivo por apresentar condições climáticas satisfatórias, sendo que atualmente esta oleaginosa é cultivada em todos os...

Biología reproductiva del lenguado Paralichthys orbignyanus: Maduración y potencial reproductivo en ejemplares cultivados y salvajes
Provedor de dados: 20
Autores: Radonic, M.
Intensive culture of teleost fish introduces changes over the environmental conditions found in their spawning grounds, leading to reproductive dysfunctions. The manipulation of these parameters (photoperiod, temperature) represents a common technique to alter the reproductive rhythms and enhance the spawnings in terms of quality and quantity. Nevertheless, for each species some modifications or adjustments have to be done according to their reproductive strategies. The advantages of manipulating those parameters are primarily to schedule the spawning for a desired period of time and to obtain good quality and quantity eggs. Many factors such as tank dimension, light intensity, nutritional status and husbandry of broodfish and minimum stress level have...

Provedor de dados: 58
Autores: Quadros,Cedenir Pereira de; Duarte,Marta Cristina Teixeira; Pastore,Gláucia Maria.
In this study, we investigate the antimicrobial effects of a mixture of a biosurfactant from Bacillus subtilis and an alkaline lipase from Fusarium oxysporum (AL/BS mix) on several types of microorganisms, as well as their abilities to remove Listeria innocua ATCC 33093 biofilm from stainless steel coupons. The AL/BS mix had a surface tension of around 30 mN.m-1, indicating that the presence of alkaline lipase did not interfere in the surface activity properties of the tensoactive component. The antimicrobial activity of the AL/BS mix was determined by minimum inhibitory concentration (MIC) micro-assays. Among all the tested organisms, the presence of the mixture only affected the growth of B. subtilis CCT 2576, B. cereus ATCC 10876 and L. innocua. The...

Autores: Queiroz,MR; Mamede,CC; Fonseca,KC; Canabrava,LCMN; França,LV; Silva,MC; Stanziola,L; Beletti,ME; Canabrava,HAN; Oliveira,F.
A myotoxin phospholipase A2 homologue, BmooMtx, was isolated from the venom of Bothrops moojeni by a combination of ion-exchange chromatography on DEAE-Sephacel column and gel filtration on Sephadex G-75. SDS-PAGE showed the enzyme to be a monomer with a molecular weight of 16,500. BmooMtx induced release of creatine kinase and morphological analyses indicated that it provoked an intense myonecrosis, with visible leukocyte infiltrate and damaged muscle cells 24 hours after injection. Anti-BmooMTx antibodies partially neutralized the myotoxic activity of BmooMtx and crude B. moojeni venom, as judged by determination of plasma creatine kinase levels and histological evaluation of skeletal muscle in mice. Anti-BmooMTx antibodies were effective in reducing the...

Biological efficiency of Agaricus brasiliensis cultivated in compost with nitrogen concentrations
Provedor de dados: 75
Autores: Siqueira,Félix G de; Martos,Emerson T; Silva,Evânia Geralda da; Silva,Romildo da; Dias,Eustáquio S.
The production of compost is one of the most important steps for the cultivation of any species of mushroom. For the Agaricus species, this step is even more complex because it depends on the performance of different microorganisms that act on the substrate, turning it into selective compost that promotes the growth of the fungus to be cultivated. Among the various factors that affect the microbial activity, the initial concentration of nitrogen is considered one of the most important. Due to the lack of conclusive studies about that, the aim of this study was to evaluate the productivity and biological efficiency of Agaricus brasiliensis in compost prepared with different initial concentrations of nitrogen, according to the composting methodology and to...

Autores: Nunes,Adrise Medeiros; Nava,Dori Edson; Müller,Fernanda Appel; Gonçalves,Rafael da Silva; Garcia,Mauro Silveira.
The objective of this work was to study the biology and parasitic potential of Doryctobracon areolatus on larvae of Anastrepha fraterculus. The egg-adult period, the sex ratio, the longevity, the pupal viability, and the parasitism rate of D. areolatus were determined in laboratory, using A. fraterculus as host. The parasitoid development from oviposition to adult emergence required 25.00±1.70 days, the sex ratio was 0.62±0.09, and the mean longevity was 16.36±3.62 days for males and 10.24±1.71 days for females. The mean parasitism rate was 53.50±8.93%, varying from 41.60 to 68.60%, which shows the potential of this parasitoid for biological control of A. fraterculus.

Biology of Bemisia tabaci (Genn.) B biotype (Hemiptera, Aleyrodidae) on tomato genotypes
Provedor de dados: 63
Autores: Oriani,Maria Auxiliadora de Godoy; Vendramim,José Djair; Vasconcelos,Cristina Jensen.
Brazil is one of the main tomato (Solanum lycopersicum) producers worldwide. Nevertheless, considerable part of the production is lost due to Bemisia tabaci (Genn.) B biotype attacks. Resistant plants can be an important method for controlling this pest in an integrated pest management. Tests for evaluating some biological aspects of B. tabaci were carried out on 18 tomato genotypes, in controlled laboratory greenhouse conditions. Thirty-day-old plants placed in plastic cages were infested with 20 whitefly pairs each, for 24 h. The development of at least 30 eggs in three leaflets per plant (repetition) was observed until adult emergence. The development period of insects grown in LA1335, PI365928 and LA722 genotypes took three days longer when compared to...

Biology of growth of Hoplias aff. malabaricus (Bloch, 1794) in a shallow pampean lake (Argentina)
Provedor de dados: 83
Autores: Balboni,Leandro; Colautti,Dario César; Baigún,Claudio Rafael Mariano.
The trahira Hoplias aff. malabaricus is a top predator in pampean shallow lakes and is highly appreciated by recreational anglers and artisanal fishermen. Trahira growth from Yalca shallow lake was determined by lepidological analysis and age validated by marginal increment. When growth was fitted to the von Bertalanffy model, annual classes exhibited a bimodal pattern as a result of the presence of spring and summer annual cohorts associated with a three month spawning season, each period in turn showing different growth patterns. The trahira population-age structure at Yalca shallow lake showed a truncated profile with very low numbers of large adults and few individuals older than three to four years, thus producing an unbalanced length-structure...

Autores: Lopes,Marcos Neves; Cândido,Magno José Duarte; Pompeu,Roberto Cláudio Fernandes Franco; Silva,Rodrigo Gregório da; Lopes,José Wellington Batista; Bezerra,Francisco Marcus Lima.
To evaluate biomass components of Massai grass under five doses of N (0, 150, 300, 450 and 600 mg N/dm³ soil) during three cycles of growth (establishment, regrowth 1 and regrowth 2) this study was carried out. The experiment was carried out in a greenhouse, in a completely randomized design with measures repeted over time and five replications. In the three cycles, nitrogen doses had increasing linear effect on green herbage dry matter (GHDM), green leaf dry matter (GLDM), on the tiller population density (TPD) and on forage density. Canopy height and foliage height were the highest ones in establishment of regrowth 2, respectively, and they decreased at the highest doses of nitrogen. Irrigation depth was the greatest at the highest doses and in regrowth...

Crop, weeds and arthropods were sampled in conventionally and organically cultivated spring- and winter-sown cereal fields. Weed biomass was much higher in organically cultivated fields, while arthropod biomass hardly showed any differences. Results from very weedy areas of organically grown fields indicate that a more extensive management allowing even more weeds may be favourable to insects and the animals feeding on them.

Biomimetic nano-assembly formation offers a convenient and bio friendly approach to fabricate complex structures from simple components with sub-nanometer precision. Recently, extract from cells of microorganism/plant origin have emerged as a simple and viable route for the synthesis of metal and inorganic material nano-particles. In the present study, we have extended biological synthesis of nano-particles to organic molecules, namely the anticancer agent, 5-fluorouracil (5-FU) using Aloe vera leaf extract. The formation of 5-FU nano- particles was assessed by UV, FT-IR and fluorescence spectroscopic techniques. Transmission electron microscopy and atomic force microscopic techniques confirmed nano-size of the synthesized particles. Importantly, the...

BioPax and SBML output from Reactome: where we are, where we are heading
Provedor de dados: 17
Autores: David Croft.
Reactome is a free, open-source, open access, pathway database. Currently, Reactome has over 5000 human proteins, involved in over 4000 manually curated reactions.  Additionally, it has nearly 30,000 reactions inferred by orthology projection from human to 20 other model organisms.  Facilities exist for exporting single pathways or the entire database to either BioPax or SBML.  SBML generation now uses libSBML, ensuring syntactic correctness, and has adopted MIRIAM URIs for references to external databases.  For the future, we anticipate that users will be able to submit a list of species to Reactome and obtain as an output customized BioPax or SBML, based on reactions extracted from Reactome.

Biophysical and Economic Uncertainty in the Analysis of Poverty Impacts of Climate Change
Provedor de dados: 31
Autores: Hertel,   Thomas W.; Lobell,   David; Verma,   Monika.
This paper seeks to understand the main sources of uncertainty in assessing the impacts of climate change on agricultural output, international trade, and poverty. We incorporate biophysical uncertainty by sampling from a distribution of productivity shocks reflecting the impacts of climate on agricultural yields in 2030. These shocks, in turn, affect the global economy. The response of economic agents to climate change is the second source of uncertainty in our estimates. We find that, even though it is difficult to predict where in the world agricultural crops will be favorably affected by climate change, we find that the responses of output and exports can be far more robust. This is due to the fact that supply and demand decisions depend on relative...

Forest transitions (FT) occur when socioeconomic development leads to a shift from net deforestation to reforestation; these dynamics have been observed in multiple countries across the globe, including the island of Puerto Rico in the Caribbean. Starting in the 1950s, Puerto Rico transitioned from an agrarian to a manufacturing and service economy reliant on food imports, leading to extensive reforestation. In recent years, however, net reforestation has leveled off. Here we examine the drivers of forest transition in Puerto Rico from 1977 to 2000 at two subnational, nested spatial scales (municipality and barrio) and over two time periods (1977-1991 and 1991-2000). This study builds on previous work by considering the social and biophysical factors that...

Biophysical Mechanisms Supporting Conscious Perception: Prospects for an Artificial Astrocyte
Provedor de dados: 17
Autores: Alfredo Pereira Jr.
In perceptual processes, signals carrying information about a stimulus are transmitted through multiple processing lines to populations of receptive neurons and thalamocortical circuits, leading to the formation of a spatial ensemble of local field potentials. This paper addresses the problem of how the brain integrates patterns embodied in local fields to (re)construct the stimulus in a conscious episode. Four examples of human perception are given to illustrate the requirements of the integrative process. Considering the strategic position of astrocytes, mediating somatic signals carried by blood flow and information carried by the neuronal network, as well as their intrinsic information processing capabilities, these cells are in an adequate condition...

Biophysical visual virtual reality in retinotopic visual areas
Provedor de dados: 17
Autores: Istv&amp;#xe1;n B&amp;#xf3;kkon; Jack Tuszynski; Vahid Salari.
Previously, we have pointed out that biophoton production can be a controlled process that originates from regulated redox/radical reactions. Our biophoton experiments support the notion that various visual related phenomena such as discrete retinal noise, retinal phosphenes as well as negative afterimages are due to biophotons. We have also suggested a new model, stating that the brain is able to create biophysical pictures in retinotopic visual areas via redox regulated biophotons of synchronized neurons. According to our interpretation, visualization (imagery) is a special kind of representation i.e., visual imagery requires peculiar inherent biophysical processes. Our idea of biophysical visual virtual reality in retinotopic areas may be a possible...

Autores: Andres Metspalu.
Biobanks are an important source to obtain samples and data for research purposes for a wide array of communities. In fact, sharing of bio-resources and data is an integral part of a biobank&amp;#x27;s role. For an effective partnership a list of requirements or needs have to be met, assuring quality of the resources shared as well as quality of the collaboration in general. Tracking and documenting bio-resource sharing and collaborations of a biobank can be seen as one indicator of the &amp;#x22;impact&amp;#x22; a biobank has to the field. As an example, the practice of the Estonian Genome Center of the University of Tartu is presented.

This paper explores whether regionally produced organic milk has a chance in the Berlin school milk market, i.e. the general offer and the level of acceptance of school milk as well as the opportunities and challenges of critical importance were analysed. Representatives of Berlin’s elementary schools and daycare centres were interviewed about their school milk situation and conclusions are drawn for a potential market entrance of local organic dairies: Daycare centres seem to be a good trading partner for organic dairies, due to their organisational structure and need for pure milk in larger packaging as well as their constant demand.

Autores: Erden,Emre; Kaymaz,Yasin; Pazarlioglu,Nurdan Kasikara.
In this study, lyophilized Trametes versicolor biomass is used as a sorbent for biosorption of a textile dye, Sirius Blue K-CFN, from an aqueous solution. The batch sorption was studied with respect to dye concentration, adsorbent dose and equilibrium time. The effect of pH and temperature on dye uptake was also investigated and kinetic parameters were determined. Optimal initial pH (3.0), equilibrium time (2 hrs), initial dye concentration ( 100 mg l-1) and biomass concentration (1.2 mg l-1) were determined at 26ï¿½C. The maximum biosorption capacity (q max) of Sirius Blue K-CFN dye on lyophilized T. versicolor biomass is 62.62 mg/g. The kinetic and isotherm studies indicated that the biosorption process obeys to a pseudo-second order model and Langmuir...

Recent publications on human appropriation of Net Primary Production (NPP) raise the question of how much of the biosphere&amp;#x2019;s productivity we can appropriate in a sustainable way.  This article brings the issue into the context of Siberian development.  In contrast to many other regions of the world, the population density in Siberia is still very low as compared to the NPP supplied by regional ecosystems. Hence, it is not too late to raise the question on how much of the NPP supplied by Siberian ecosystems we can appropriate in a sustainable way.

Fungi collected from Brazilian soil and decomposing plants were screened for pectinase production. R. microsporus var. rhizopodiformis was the best producer and was selected to evaluate the pectic enzyme production under several nutritional and environmental conditions. The pectinase production was studied at 40ºC, under 28 carbon sources-supplemented medium. The inducer effect of several agro-industrial residues such as sugar cane bagasse, wheat flour and corncob on polygalacturonase (PG) activity was 4-, 3- and 2-fold higher than the control (pectin). In glucose-medium, a constitutive pectin lyase (PL) activity was detected. The results demonstrated that R. microsporus produced high levels of PG (57.7 U/mg) and PL (88.6 U/mg) in lemon peel-medium.

Biotechnology in Agriculture and Forestry: Economic Perspectives
Provedor de dados: 31
Autores: van Kooten,   G. Cornelis.
Economists are rarely brought into the interdisciplinary research until the biophysical scientists have developed their models, made their measurements or completed their research task. The research economist is then brought in to do what amounts to a consulting task – provide some numbers that indicate impacts on the economy and employment. In this paper, I begin by illustrating cases from forestry where this leads to erroneous and costly policy outcomes. However, the main objective of this paper is to examine the role of genetic engineering in forestry and agriculture. In forestry, planting of genetically-modified (GM) tree species is nearly non-existent, with the exception of hybrid poplar that is used to produce pulp or fuel. However, as explored here,...

En 1994 se conformó un grupo de investigación científica y desarrollo tecnológico guiado por la demanda del sector agroindustrial de la región del noroeste argentino, que además de las consideraciones económicas intrínsecas del proceso productivo, tuvo en cuenta para sus investigaciones, aspectos sociales y ambientales. Las premisas conceptuales del trabajo científico fueron el estudio, la preservación y el aprovechamiento de la biodiversidad, en conjunción con la búsqueda continua de alternativas de manejo fitosanitario lo menos reñidas posible con la salud humana y ambiental. Fue así que en 1997 se inició el primer Programa Nacional de Mejoramiento Genético de la Frutilla en Argentina, que desde el INSIBIO (CONICET-UNT) en Tucumán coordinó el trabajo de...

Bird frugivory and seed germination of Myrsine umbellata and Myrsine lancifolia (Myrsinaceae) seeds in a cerrado fragment in southeastern Brazil
Provedor de dados: 49
Autores: Guerta,Rafael Soave; Lucon,Lucas Gustavo; Motta-Junior,José Carlos; Vasconcellos,Luís Augusto da Silva; Figueiredo,Rodolfo Antônio de.
Birds are known to be important dispersers of plants, since the passage of seeds through the digestive tract often has a positive influence on germination percentage and speed. In this study, proportions of germination in different substrates were compared between Myrsine (Myrsinaceae) seeds collected manually and those ingested by birds. The guilds of birds that fed on M. umbellata and M. lancifolia were identified and comprise 24 and 12 species, respectively. A higher germination proportion was found among seeds defecated by birds and sowed in the study area. The study also found differences between the guilds of frugivores in both synchronopatric species. Therefore, we suggest that M. umbellata and M. lancifolia are important food sources by birds that...

Bird surveys for REDD+: avian communities indicate forest degradation in a Peruvian coffee landscape
Provedor de dados: 17
Autores: Raf Aerts; Sarah Spranghers; Bruno Verbist; Luc Lens; Cagan Sekercioglu.
Shade coffee cultivation in the Peruvian Andes assists in reducing emissions from deforestation because it avoids conversion to non-forest land uses such as coca and sun grown coffee farming.  REDD+ is a potential finance mechanism which may provide incentives for local coffee cooperatives to maintain high shade tree cover.  REDD+ has potential multiple benefits other than carbon sequestration, including the conservation of biodiversity.  When monitoring for REDD+, surveys of bird biodiversity may prove to be particularly valuable: apart from their high intrinsic value and their value as essential ecosystem service providers, birds inhabiting forest habitats are extremely sensitive to forest loss and forest degradation and are therefore potential useful...

Birds from cerradão woodland, an overlooked forest of the Cerrado region, Brazil
Provedor de dados: 84
Autores: Cavarzere,Vagner; Moraes,Gabriel Parmezani; Dalbeto,Andreli Cristina; Maciel,Fernanda de Góes; Donatelli,Reginaldo José.
The Cerrado region still receives relatively little ornithological attention, although it is regarded as the only tropical savanna in the world considered to be a biodiversity hotspot. Cerradão is one of the least known and most deforested Cerrado physiognomies and few recent bird surveys have been conducted in these forests. In order to rescue bird records and complement the few existing inventories of this under-studied forest type in the state of São Paulo, we looked for published papers on birds of cerradão. Additionally we surveyed birds at a 314-ha cerradão remnant located in central São Paulo, Brazil, from September 2005-December 2006 using unlimited distance transect counts. Out of 95 investigations involving cerradão bird studies, only 17 (18%)...

Birds from open environments in the caatinga from state of Alagoas, northeastern Brazil
Provedor de dados: 103
Autores: Araujo,Helder Farias Pereira de; Rodrigues,Roberta Costa.
Even though the caatinga has been identified as an important area of endemism for South American birds, few studies have been conducted on the distribution, evolution and ecology of birds in this biome. Understanding how habitats contribute to maintain the regional bird diversity is extremely important. In this study, carried out in the backwoods of the state of Alagoas, we present a rapid survey of a caatinga area and discuss the composition of the avifauna in different habitats. From the record of 105 species, we estimated a local richness of 120 (± 5) species. Among the areas surveyed, the dense caatinga shrub areas contributed with more than 42% of the species, holding most of the forest-dependent birds. The open field areas and the vegetation patches...

Birds of the Grota do Angico Natural Monument in the semi-arid Caatinga scrublands of northeastern Brazil
Provedor de dados: 49
Autores: Ruiz-Esparza,Juan; Gouveia,Sidney Feitosa; Rocha,Patricio Adriano da; Beltrão-Mendes,Raone; Ribeiro,Adauto de Souza; Ferrari,Stephen Francis.
An inventory of the avian fauna of the Grota do Angico Natural Monument in the Caatinga of northern Sergipe, Brazil, revealed the presence of at least 140 species, including nine that are endemic to the Caatinga and seasonal forest adjacent. Despite the limited scope of the study (two expeditions in July and August, 2008), the species richness recorded at the site appeared to be typical of the region and the Caatinga biome.

Birth Control Does Not Significantly Alter Women&amp;#x2019;s Preferences for Variants of Men&amp;#x2019;s Voices
Provedor de dados: 17
Autores: Jason W. J. W. W. Whitaker; Ryan R. S. Setten; Ulv U. A. Ankerstjerne.
Research shows that women&amp;#x2018;s preferences for masculine voices (low pitch) vary as a function of the menstrual cycle, becoming positively augmented around ovulation. The proximate cause catalyzing this effect is attributed to fluctuating estrogen levels. Thus, the introduction of hormonally based birth control has been to shown to have a dampening effect in experiments researching women&amp;#x2018;s preference of dimorphic secondary sexual characteristics. However, this dampening effect has not yet been explored in respect to women&amp;#x2018;s preferences for masculine voice types. This experiment sought, first, to investigate the effect of birth control on subjects off and on birth control; and, second, to replicate past findings:...

Birth weight patterns by gestational age in Brazil
Provedor de dados: 42
Autores: Pedreira,Carlos E.; Pinto,Francisco A.; Pereira,Silvia P.; Costa,Elaine S.
BACKGROUND AND OBJECTIVES: We present an updated birth weight-for-gestational-age portrait, based on nearly 8 million observations of an ethnic-mixed population. It comprises the first comprehensive charts with Brazilian data. This contribution intends to assist clinicians in classifying fetal growth, to provide a reference for investigations of predictors and to show the consequences of small and large patterns for gestational age delivery. Most of the reference data for assessing birth weight for gestational age deal with insufficient sample size, especially at low gestational age. Population-based studies with considerably large sample size refer to data collected more than 15 years ago. METHODS: We accomplished a population-based study on births in all...

Autores: Lopes,P.C.F.; Nunes,N.; Dias,L.G.G.G.; Pereira Neto,G.B.; Almeida,R.M.; Souza,A.L.G.; Belmonte,E.A.
The effects of inspired oxygen fractions (FiO2) of 1 and 0.6 on bispectral index (BIS) in dogs with high intracranial pressure, submitted to a continuous rate infusion of propofol were evaluated. Eight dogs were anesthetized on two occasions, receiving, during controlled ventilation, an FiO2 = 1 (G100) or an FiO2 = 0.6 (G60). Propofol was used for induction (10mg.kg-1, IV), followed by a continuous rate infusion (0.6mg.kg-1.minute-1). After 20 minutes, a fiber-optic catheter was implanted on the surface of the right cerebral cortex to monitor the intracranial pressure, the baseline measurements of BIS values, signal quality index, suppression ratio number, electromyogram indicator, end-tidal carbon dioxide partial pressure, mean arterial pressure,...

Black Sea "Lake" reservoir age evolution since the Last Glacial - Hydrologic and climatic implications
Provedor de dados: 5
Autores: Soulet, Guillaume; Menot, Guillemette; Garreta, Vincent; Rostek, Frauke; Zaragosi, Sebastien; Lericolais, Gilles; Bard, Edouard.
Chronologies of sediments that document the last glacial history of the Black Sea "Lake" are hampered by issues relating to reservoir age. Regulated by basin hydrology, reservoir ages represent a tool that could potentially be used to better understand the response of Black Sea "Lake" hydrology to climate change. Therefore, deciphering reservoir age evolution is crucial both for better constraining the basin chronological framework and for providing new insights into our understanding of Black Sea "Lake" hydrology. By tuning a meaningful new high-resolution geochemical dataset (obtained from core MD04-2790) to a climate reference record, here, we propose a reliable chronology spanning the last 32 kyr BP. The chronology is compared to a large AMS...

Blackrot in appel: Effecten van verwijderen vruchtmummies
Provedor de dados: 21
Autores: Timmermans, Bart.
Blackrot is een schimmelaantas- ting bij appels die recent in Nederland ontdekt is en afkomstig lijkt uit zuidelijker landen. De schimmel overwintert onder meer op vruchtmummies en komt dan ook vooral voor op appelrassen die hun mummies lang vasthouden zoals Elstar. In een driejarig onderzoek is het effect van het ver- wijderen van de mummies als infectiebron op de aantasting bestudeerd. De resultaten zijn veelbelovend: Zo’n 60-90 procent afname van het aantal aangetaste appels bij de oogst.

Bladpootkreeften in Nederland, een overzicht (Crustacea: Branchiopoda: Phyllopoda)
Provedor de dados: 16
Autores: Soesbergen, M.P.
Vreemde levensvormen zoals trilobieten en degenkrabben hebben altijd al tot de verbeelding gesproken. In ons land hebben we de bladpootkreeften. Binnen deze groep zijn twee vormen te onderscheiden, vijf centimer grote trilobietachtige kreeften met een  groot schild en slanke, kleurrijke garnaalachtige dieren, die met de buikzijde omhoog zwemmen. Ze zijn beide aangepast aan het leven in een bijzonder biotoop: tijdelijke watertjes, zoals karresporen en snel opdrogende poelen. Ze komen al 200 miljoen jaar in onveranderde vorm voor en behoren tot de oudst levende soorten op aarde.

Blastodinium spp. infect copepods in the ultra-oligotrophic marine waters of the Mediterranean Sea
Provedor de dados: 5
Autores: Alves-de-souza, C.; Cornet, C.; Nowaczyk, A.; Gasparini, S.; Skovgaard, A.; Guillou, L.
Blastodinium are chloroplast-containing dinoflagellates which infect a wide range of copepods. They develop inside the gut of their host, where they produce successive generations of sporocytes that are eventually expelled through the anus of the copepod. Here, we report on copepod infections in the oligotrophic to ultra-oligotrophic waters of the Mediterranean Sea sampled during the BOUM cruise. Based on a DNA-stain screening of gut contents, 16% of copepods were possibly infected in samples from the Eastern Mediterranean infected, with up to 51% of Corycaeidae, 33% of Calanoida, but less than 2% of Oithonidae and Oncaeidae. Parasites were classified into distinct morphotypes, with some tentatively assigned to species B. mangini, B. contortum, and B. cf....

Blood glucose regulation during fasting in rats under food restriction since birth
Provedor de dados: 52
Autores: Vitoriano,Adriana de Souza; Malta,Ananda; Barrena,Helenton Christian; Furlan,Maria Montserrat Diaz Pedrosa; Bazotte,Roberto Barbosa; Gazola,Vilma Godoi.
The effect of severe food restriction since birth on regulation of fasting glycemia in male Wistar rats was investigated. The control group (CG) had free supply of chow, while the restriction group (RG) received 50% of the amount ingested by the CG. The experiments were done in adult (60 days) overnight fasted rats in which glycemia, liver free glucose levels and hepatic glycogen concentration were measured. In part of the experiments in situ liver perfusion was done. The results showed that livers from the RG had higher glycogenolysis rates but lower gluconeogenesis rates from L-alanine (10 mM). Since RG showed maintained glycemia during fasting, it could be concluded that livers from RG produced glucose preferentially from glycogenolysis in detriment of...

Blueberry pollination in southern Brazil and their influence on fruit quality
Provedor de dados: 94
Autores: Silveira,Tiago Madruga Telesca da; Raseira,Maria do Carmo Bassols; Nava,Dori Edson; Couto,Marcelo.
Blueberry (Vaccinium ashei) is a relatively new crop in cultivation under Southern Brazil conditions. The first collection introduced in the area was formed by rabbiteye cultivars which need insect pollinators and also pollinizers. The aim of this work was to observe if there were differences between pollinizers on fruit quality of the commercial cultivar and also to observe the most effective and frequent insect pollinators, under natural conditions. It was concluded that pollen source has an effect on quality of blueberry fruits. Bumblebees are the most efficient pollinators; however the species found in southern Brazil are different from the ones mentioned in the U.S. literature.

Bodenfruchtbarkeit im Öko-Betrieb. Untersuchungsmethoden
Provedor de dados: 21
Autores: Kolbe, Hartmut; Schuster, Martina.
In den ökologisch wirtschaftenden Gemischtbetrieben lässt sich die Bodenfruchtbarkeit durch die weitgehend geschlossenen Nährstoffkreisläufe relativ einfach absichern. Bei spezialisierteren Betriebsformen, bei viehloser Wirtschaftsweise oder auf Standorten mit geringer natürlicher Fruchtbarkeit besteht jedoch ein höheres  Gefährdungspotenzial.  Um die Bodenfruchtbarkeit langfristig zu erhalten, sollten die Struktur der Böden und die Nährstoff- und Humusversorgung regelmäßig überprüft werden. Nur durch vorsorgende Untersuchungen kann rechtzeitig bemerkt werden, ob ein Wachstumsfaktor ins Minimum gerät. Biologische, physikalische und chemische Kenngrößen dienen dabei als Kriterien für die Beurteilung der Bodenfruchtbarkeit.  Ziel der Broschüre ist es, im...

Bodenüberwachung nach der Umstellung des Guts Rheinau auf biologische Bewirtschaftung - Berichtsperiode 1999-2010
Provedor de dados: 21
Autores: Mäder, Paul; Pfiffner, Lukas; Fließbach, Andreas.
Mit der Umstellung des Gutes Rheinau von konventionell integrierter Bewirtschaftung auf bio-dynamische Wirtschaftsweise im Jahre 1998 wurde ein Monitoring der Bodenfruchtbarkeit begonnen, dass die biologische Veränderung im Boden während der Umstellungsphase dokumentieren sollte. Die ersten Bodenproben wurden 1999 auf drei Ackerschlägen und einer permanenten Naturwiese gezogen und dann wurden im Jahr 2002, 2005 und 2010 auf den in 1999 definierten Teilflächen je Schlag weitere Bodenproben entnommen. Neben mikrobiologischen Bodenparametern (mikrobielle Biomasse, Basalatmung, Dehydrogenaseaktivität) wurden die Regenwurmpopulationen und auch chemische Bodenparameter und lösliche und nachlieferbare Fraktionen wichtiger Nährstoffe ermittelt. Ausserdem erfolgte...

Body composition and net requirements of protein and energy for weight gain of Nellore and crossbreed steers finished under grazing
Provedor de dados: 96
Autores: Sant´Ana,N.F.; Fontes,C.A.A.; Silva,R.S.T.; Garcia,C.S.; Vieira,R.A.M.; Rocha,T.C.
The objective of this work was to evaluate body composition and net requirements of protein and energy for weight gain of Nellore and crossbred F1 Limousin-Nellore steers finished on Mombasa grass pastures. Mombasa grass (Panicum maximum) pastures were managed under intermitent stocking during the rainy season, with a forage offer of 8% of the body weight (BW) based on the dry matter of green leaves. Twenty-four steers were used: 12 were Nellore (386 kg SBW) and 12 were F1 Limousin-Nellore (397 kg SBW). Changes in body composition in a 104-day experimental period were evaluated according to the comparative slaughter method. After slaughter, all body components were weighed and representative samples of carcass (HH section) and non-carcass tissues were...

The objectives of the present study were to describe and compare the body composition variables determined by bioelectrical impedance (BIA) and the deuterium dilution method (DDM), to identify possible correlations and agreement between the two methods, and to construct a linear regression model including anthropometric measures. Obese adolescents were evaluated by anthropometric measures, and body composition was assessed by BIA and DDM. Forty obese adolescents were included in the study. Comparison of the mean values for the following variables: fat body mass (FM; kg), fat-free mass (FFM; kg), and total body water (TBW; %) determined by DDM and by BIA revealed significant differences. BIA overestimated FFM and TBW and underestimated FM. When compared...

Body Condition Scoring bei Milchziegen
Provedor de dados: 21
Autores: Aschenbach, Franziska; Rahmann, Gerold.
Body Condition Score kann eine Möglichkeit sein, den Ernährungszustand von Milchziegen besser einzuschätzen. In der Literatur liegen jedoch keine eindeutigen Aussagen über die Eignung für Milchziegen im Ökolandbau vor. Deswegen wurde 2009 mit der 80-köpfigen Milchziegenherde in Trenthorst (Schleswig-Holstein) untersucht, ob ein BCS oder die Wiegung als Bewertungsmaßstab für den Ergänzungszustand herangezogen werden soll.

Body measurements and serum lipid profile of overweight adult dogs fed diet with containing conjugated linoleic acid
Provedor de dados: 65
Autores: Rivera,Nancy Lorena Montaño; Félix,Ananda Portela; Ferreira,Fabiano Montiani; Silva,Ana Vitória Fisher da; Maiorka,Alex.
Studies with human beings and animals have shown that dietary conjugated linoleic acid (CLA) promotes changes in body structure, markedly, body fat reduction. This research aimed to assess the effect of CLA (60% of conjugated linoleic acid methyl ester, at the proportion of 1:1 of the 9, 11: 10, 12 isomers) on changes in body weight, subcutaneous tissue thickness, body fat mass and concentration of serum lipids (triacylglycerols, total cholesterol, LDL and HDL) in overweight dogs. Dogs of different breeds weighting 16.85±7.13 assigned in a randomized assay. Two types of diets were offered for 120 days: control (-CLA) and test (+CLA, 0.3%). There was no difference between control and test groups considering body weight and serum levels of triacylglycerols,...

Body size, symmetry and abundance of Euxesta stigmatias (Loew) and Euxesta sororcula (Wiedemann) (Diptera: Ulidiidae) in a natural reserve and in a guava orchard in Uberlândia, MG, Brazil
Provedor de dados: 82
Autores: Souto,KCFL; Pereira,CD; Lomônaco,C.
The aim of this study was to comparatively characterize the monthly variation and the sex ratio of Euxesta stigmatias (Loew) and Euxesta sororcula (Wiedermann) populations from a natural reserve and from a guava orchard. It was also investigated whether density and the climate factors affected the individuals' size and fluctuating asymmetry (FA). In both environments, E. sororcula predominated over E. stigmatias. The number of individuals of E. sororcula collected in the ecological station was significantly lower than the number of individuals caught in the orchard. However, the number of captured individuals of E. stigmatias did not differ between environments. Significant sex ratio differences were detected between the collection sites. Female's...

Body size, symmetry and courtship behavior of Dysdercus maurus distant (Hemiptera: Pyrrhocoridae)
Provedor de dados: 82
Autores: Jorge,AS; Lomônaco,C.
This study analyses the role of body size and symmetry in the sexual selection and courtship behavior of Dysdercus maurus Distant. Sexual conflicts signaled by coercive mating, female resistance, and pre-copulation fights illustrate the mating system. Male-female struggles were observed in all mating attempts. Females tried to reject males by pushing or running and even by vigorously shaking their bodies, in attempts to dislodge the male from their dorsum. In spite of sexual conflicts during courtship, females actively chose their mates based on morphological and behavioral traits. Larger males with more symmetrical tibiae and longer tarsi that are better copula imposers were more successful in sexual competition. Evidence is presented that sexual conflict...

Bønder som klimahelte: Kan og vil landbruget bidrage?
Provedor de dados: 21
Autores: Svendsen, Gert Tinggaard; Pedersen, Karin Hilmer.
Kan og vil landbruget bidrage til reduktion af drivhusgasser? Undersøgelser tyder på, at der i landbrugssektoren findes et stort og uudnyttet potentiale for relativt billig reduktion af drivhusgasser. Selvom måling af reduktion i udledning af drivhusgasser inden for landbrugssektoren er behæftet med omfattende usikkerhed, vil man ved at måle reduktion indirekte gennem relative ændringer i produktionsprocesser kunne inkludere landbrugssektoren i reguleringsordninger. Spørgsmålet er, hvordan man kan få landbruget til at bidrage? Vi overvejer brugen af standarder, grønne afgifter og omsættelige kvoter. Vi finder, at landbrugssektoren vil have en ikke ubetydelig interesse i at få tildelt kvoter og deltage i det europæiske kvotesystem, EU ETS. Landbrugets...

The objective of this study was to investigate the bone regeneration of a "gold standard" (autograft) from iliac crest associated with cellular therapy in rabbits. A bone defect was created with 10x5x5mm in 28 rabbit mandibles. The control group animals (n=14) were repaired with autograft of iliac crest and the experimental group animals (n=14) received iliac crest autograft in association with mononuclear cells from the bone marrow of the femur. Weekly radiographs were taken of the surgery region and histological analyses was performed in seven animals in each group at 15 days and in seven animals of each group at 30 days after the surgery. A gradual increase of bone density was observed and the experimental animals presented the bone bridge in 85.7%...

Autores: Paull, John.
Green Harvest is an introduction to four Australian organic farmers and gardeners. Each example is framed within the context of an historical account which is itself subsumed within Jones’ own “four key principles” of organics. At the outset, the author alerts us to her view that “History is both fact and fiction” (p.ix). It is a novel approach which will not appeal to all, and will be unsettling for some. The author states that: “Environmental history is the lens through which I have examined organic growers’ changing ideas about  health and environment” (p.ix). The author claims that: “I have identified four key principles, each founded on organic farmers’ and gardeners’ belief in the dependence of health on the biophysical environment. These four...

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-Border Trade in West Africa?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in...

This study examines the impact of border and distance on price transmission between tomato in Ghana and Burkina-Faso. The analysis applies a linear and a regime-switching vector error correction model to estimate wholesale prices of tomato in four tomato markets in Ghana and a producer market in Burkina-Faso. The estimated...

Bounded Learning Efficiency and Sources of Firm Level Productivity Growth in Colombian Food Manufacturing Industry
Provedor de dados: 31
Autores: Shee,   Apurba; Stefanou,   Spiro E.
The measurement of productivity fluctuations has been the focus of decades-long interest.  In addition to broad structural forces driving productivity changes, there is more recent interest in measuring and identifying the heterogeneous forces driving these changes.  A major force is learning-by-doing which is used by economists to describe the phenomenon of productivity growth arising from the accumulation of production experience by a firm.  This paper proposes a bounded learning concept with the learning progress function characterized by the degree of efficiency and the specification of the learning progress as a logistic function capturing both the slow start-up and the limit in learning progress. The inter-firm learning inefficiency is defined as the...

Bounds on Quantile Treatment Effects of Job Corps on Participants' Wages
Provedor de dados: 31
Autores: Blanco,   German; Flores,   Carlos A.; Flores-Lagunes,   Alfonso.
This paper assesses the effect of the U.S. Job Corps (JC), the nation's largest and most comprehensive job training program targeting disadvantaged youths, on wages. We employ partial identification techniques and construct informative nonparametric bounds for the causal effect of interest under weaker assumptions than those conventionally used for point identification of treatment effects in the presence of sample selection. In addition, we propose and estimate bounds on quantile treatment effects of the program on participants' wages. In general, we find convincing evidence of positive impacts of JC on participants' wages. Importantly, we find that estimated impacts on lower quantiles of the distribution are higher, with the highest impact being in the...

Bovine mastitis in the metropolitan area of Curitiba: antibiotic resistance and antimicrobial control of the infection
Provedor de dados: 52
Autores: Parada,José Luis; Gonçalves,Dicezar; Soccol,Vanete Tomaz; Lima,Marisa; Soccol,Carlos Ricardo.
A study from cows with mastitis was performed and Staphylococcus aureus was the predominant pathogen in 46.4 % among 153 studied strains from 276 milk samples of infected cows. Antibiotic resistance of 71 S. aureus isolates was determined in order to search resistant strains to antibiotics of clinical interest, as well as to determine their degree of multi-resistance. It was found that 60% of the S. aureus strains presented resistance to β-lactams, but none to oxacillin, teicoplamin or vancomycin. On the other hand, with the aim of reducing the use of current antibiotics and their associated resistance, a new formulation was introduced. The antimicrobial compounds (P22-P32), demonstrated to be effective in 55% of the 76 mastitis cases studied. The use of...

Bovine parthenogenotes produced by inhibition of first or second polar bodies emission
Provedor de dados: 47
Autores: Bevacqua,Romina J.; Fernandez-Martin,Rafael; Salamone,Daniel F.
Parthenogenetic embryos are an ethically acceptable alternative for the derivation of human embryonic stem cells. In this work, we propose a new strategy to produce bovine parthenogenetic embryos inhibiting the emission of the first polar body during in vitro maturation, and allowing the extrusion of the second polar body during oocyte activation. Cytochalasin B, an inhibitor of actin microfilaments, was employed during in vitro maturation to inhibit first polar body emission or during parthenogenetic activation to block second polar body emission. Only one polar body was inhibited in each strategy in order to keep the diploid chromosome set. In experiment 1, the effect of cytochalasin B on in vitro maturation of bovine oocytes was evaluated. Most oocytes...

Brachiaria species affecting soil nitrification
Provedor de dados: 90
Autores: Fernandes,Adalton Mazetti; Andrade,Gabriel José Massoni de; Souza,Emerson de Freitas Cordova de; Rosolem,Ciro Antonio.
Nitrification can lead to substantial losses of the applied N through nitrate leaching and N2O emission. The regulation of nitrification may be a strategy to improve fertilizer N recovery and increase its agronomic efficiency. The objective of this study was to evaluate the inhibiting capacity of nitrification in soil by Brachiaria species. The greenhouse experiment was conducted using pots with 10 dm³ of a Red Latosol sample. The treatments consisted of the cultivation of three forage species (Brachiaria brizantha, B. ruziziensis and B. decumbens) and four n rates (0, 100, 200, and 300 mg/pot), and the control (without plants). In the absence of the forage plants, all N fertilization levels raised the N-NO3- soil levels, as a result of nitrification. The...

Autores: Silva, Ariadne Josiane Castoldi; Carpanezzi, Antonio Aparecido; Lavoranti, Osmir José.
Erythrina crista-galli L., Fabaceae, a medium-sized N-fixing tree, is native to flooding soils of several Brazilian biomes. Its cultivation has interest for ornamental and ecological restoration purposes. Information on seed coat dormancy is conflicting and inexact, therefore the present work aimed to verify it and to define methods for its overcoming. The study was composed by two experiments, using seed lots collected in different dates. Seeds were subjected to inducing germination treatments by chemical scarification (ACS commercial sulfuric acid, d=1,84 g/cm³) and thermic scarification (hot water). Results demonstrated high germination under acid scarification (up to 95%) and inferior when submitted to thermic scarification (reaching up to 43%);...

Breaking the Impasse in International Climate Negotiations: A New Direction for Currently Flawed Negotiations and a Roadmap for China to 2050
Provedor de dados: 31
Autores: Zhang,   ZhongXiang.
China’s unilateral pledge to cut its carbon intensity by 40-45 percent by 2020 relative to its 2005 levels raises both the stringency issue, and given that China’s pledge is in the form of carbon intensity, reliability issues concerning China’s statistics on energy and GDP. Moreover, as long as China’s commitments differ in form from those of other major greenhouse gas emitters, China is constantly confronted with both criticism on its carbon intensity commitment being less stringent and the threats of trade measures. In response to these concerns and to put China in a positive position, this paper will map out a realistic roadmap for China’s specific climate commitments towards 2050, with its main distinguishing features including China taking on absolute...

Autores: Ghoshray,   Atanu; Kejriwal,   Mohitosh; Wohar,   Mark E.
This paper examines the Prebisch-Singer Hypothesis employing new time se- ries procedures that are robust to the nature of persistence in the commodity price shocks, thereby obviating the need for unit root pretesting. Speci…cally, the proce- dures allow consistent estimation of the number of structural breaks in the trend function as well as facilitate the distinction between trend breaks and pure level shifts. In comparison with past studies, we …nd fewer cases of commodities that display negative trends thereby weakening the case for the Prebisch-Singer Hypoth- esis. Finally, a new set of powerful unit root tests allowing for structural breaks under both the null and alternative hypotheses is applied to determine whether the underlying commodity price...

Breaks and Trends in OECD Countries’ Energy-GDP Ratios
Provedor de dados: 31
Autores: Liddle,   Brantley.
This paper uses the econometrics of endogenous structural breaks to examine changes in energy intensity for OECD countries over 1960-2009. Nearly all OECD countries currently have significant negatively trending energy-GDP ratios; but for several countries those negative trends are recent, and two countries have recent significant positive trends. For several countries, energy intensity had a significant positive trend followed by a break and then a significant negative trend. Those break-dates, however, appear to have little to do with level of development (GDP per capita). Instead, among the likely causes of break timing are the volatile energy prices of the 1970s and early 1980s and the increased concern for the environment in the late 1960s and early...

Polystictus superciliaris (Wied, 1831) is a small tyrant-flycatcher endemic to mountaintops in the highlands of eastern Brazil. In this paper we present the first description of the breeding biology of P. superciliaris and estimate its reproductive success from a population inhabiting rocky outcrops. This study was conducted during 2005 in the Parque Estadual da Serra do Rola Moça, municipality of Nova Lima (20°03'S, 44°00'W), state of Minas Gerais, southeastern Brazil. Fourteen pairs of P. superciliaris were banded and monitored. The onset of the breeding season in 2005 was assumed to have been sometime before the 26th of July, while it was assumed to have ended on the 23rd of November based on the last observation of a successful brood.

Breeding ecology and reproductive traits of Brown Booby _Sula leucogaster_ etesiaca in Gorgona Natural National Park, Colombia, were studied. Adults morphometrics, eggs dimensions, chicks growth and nesting site characteristics, were examined at three different locations in the park. As with other subspecies, Brown Booby in Gorgona presents inverted sexual dimorphism, with adult females being lengthier, wider and heavier than adult males. Breeding of S. l. etesiaca results in eggs from the first deposition bigger in weight and dimensions than eggs from the second or third deposition. Growth of brown boobies chicks fit to a natural log equation: bodymass(g) = 0.8773 ln(days) + 3.3895. A variety of spawning aggregations was found, and their relationship with...

Breeding, genetic and genomic of citrus for disease resistance
Provedor de dados: 94
Autores: Machado,Marcos A.; Cristofani-Yaly,Mariângela; Bastianel,Marinês.
Although the citriculture is one of the most important economic activities in Brazil, it is based on a small number of varieties. This fact has contributed for the vulnerability of the culture regarding the phytosanitary problems. A higher number of varieties/genotypes with potential for commercial growing, either for the industry or fresh market, has been one of the main objectives of citrus breeding programs. The genetic breeding of citrus has improved, in the last decades, due to the possibility of an association between biotechnological tools and classical methods of breeding. The use of molecular markers for early selection of zygotic seedlings from controlled crosses resulted in the possibility of selection of a high number of new combination and, as...

Autores: Gärber, Ute; Idczak, Elke; Behrendt, Ulrike.
Erreger des Falschen Mehltaus an Salat ist der Pilz Bremia lactucae. Der Pilz besitzt eine hohe Variabilität und hat durch die Entwicklung neuer Rassen mehrfach die durch Züchtung erzielte Resistenz durchbrochen. Die Befallsgefahr hat insbesondere im ökologischen Anbau zugenommen, da direkte Regulierungsmaßnahmen fehlen. Die Entwicklung ständig neuer Erregerformen sowie das lokale Vorkommen einer Vielzahl an Erregerformen, erschweren dem Anbauer, die "richtige", resistente Sorte auszuwählen. Daher soll eine Methode erprobt werden, die es dem Anbauer ermöglicht, entsprechend der regionalen Anbausituation die Sorten auszuwählen, für die im Feld eine nur geringe Anfälligkeit zu erwarten ist.

Autores: GUERRA, C. C.
Os países da Europa tinham, até os anos 1990, sistemas de ensino completamente estratificados e muito diferentes entre si. Com a centralização dos projetos de ensino e pesquisa da União Européia no programa Erasmus Mundus, ocorreu uma rápida adaptação e compatibilização das grades de ensino universitário e pósuniversitário, de modo que hoje, a formação em qualquer país da União Européia é compatível e reconhecida nos demais países. Relativamente à pós-graduação, houve um incentivo muito forte aos mestrados. As universidades praticamente aboliram os 'mestrados acadêmicos' e 'mestrados profissionais', substituindo-os por cursos unificados que oferecem, ao mesmo tempo, formação aprofundada e abrangente.

Brewer's spent grain and corn steep liquor as alternative culture medium substrates for proteinase production by Streptomyces malaysiensis AMT-3
Provedor de dados: 58
Autores: Nascimento,Rodrigo Pires do; Alves Junior,Nelson; Coelho,Rosalie Reed Rodrigues.
Brewer's spent grain and corn steep liquor or yeast extract were used as the sole organic forms for proteinase production by Streptomyces malaysiensis in submerged fermentation. The influence of the C and N concentrations, as well as the incubation periods, were assessed. Eight proteolytic bands were detected through gelatin-gel-electrophoresis in the various extracts obtained from the different media and after different incubation periods, with apparent molecular masses of 20, 35, 43, 50, 70, 100, 116 and 212 kDa. The results obtained suggest an opportunity for exploring this alternative strategy for proteinases production by actinomycetes, using BSG and CSL as economically feasible substrates.

Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies...

BRIF and Variant Databases
Provedor de dados: 17
Autores: Raymond Dalgleish.
Databases of sequence variation in human genes (LSDBs) are an important resource for biology and medicine. Currently, the measurement of importance is not as objective as it might be and the establishment of impact factors would be of benefit to those who curate LSDBs. Specific issues relating to such databases are discussed.

BROADACRE FARM PRODUCTIVITY AND PROFITABILITY IN SOUTH WESTERN AUSTRALIA
Provedor de dados: 31
Autores: Islam,   Nazrul; Xayavong,   Vilaphonh; Kingwell,   Ross S.
This paper examines broadacre farm performance in south-western Australia. This region has experienced pronounced climate variability and volatile commodity prices over the last decade or so. Relationships between productivity and profitability are explored using panel data from 50 farms in the study region. The data are analysed using non-parametric methods. Components of farm productivity and profitability are measured over the period 1998 to 2008. Economies of scale and scope are shown often to be positive contributors to productivity and profitability. However, the main finding is that technical change, much more so than technical efficiency, has supplied over 68 percent of the improvement in total factor productivity for farms in the different...

Brokers vs. Retailers: Evidence from the French Imports Industry of Fresh Produce.
Provedor de dados: 31
Autores: Latouche,   Karine; Rouviere,   Elodie.
There is little discussion in the literature about trade intermediaries because data is rare. Using very original data, our article sheds light on the behavior of trade intermediaries when importing fresh fruit and vegetables in France. To do so, we distinguish among direct and indirect imports respectively operated through brokers or retailers. We then investigate the impact of country level data on the share of indirect/direct flows of imports by country of origin at the 8-digit level that enter the french market. We show that brokers are more likely to operate in context when fixed and variable costs to trade are high whereas retailers are sensitive to tariffs and product sensitivity.

Como resultado de una investigación impulsada por la justicia, se analizaron muestras provenientes de un posible derrame intencional de plaguicidas sobre colmenas con abejas. En los análisis realizados se utilizó GC-MS previa extracción con solventes orgánicos. Debido a dificultades iniciales en la identificación de plaguicidas sobre tres de las muestras, se procedió al reprocesamiento de los cromatogramas utilizando selección de las relaciones de masas m/z 158, 173 y 143. Utilizando es herramienta analítica se obtuvieron los correspondientes cromatogramas, y los espectros de masas con coincidencia frente al divulgado para el producto de descomposición de bromadiolona (PDB), determinando que tanto las abejas como las colmenas habían tenido contacto con...

Bromatologic composition of the herbaceous species of the Northeastern Brazil Caatinga
Provedor de dados: 96
Autores: Silva,D.S.; Andrade,M.V.M.; Andrade,A.P.; Carneiro,M.S.S.; Oliveira,J.S.
The objective of this work was to evaluate the chemical composition of the pool and of four species of caatinga herbaceous vegetation in the rainy and dry seasons. The experiment was conducted in three selected shrub areas at different levels of conservation. Four samples of each species (Arachis pintoi, Boerhavia diffusa, Heliotropium ternatum, Aristida adscensionis) were collected in each area and from a pool of species for determination of bromatologic composition. In the dry season, only the pool of species and the grass Aristida adscensionis were evaluated. There was a significant effect of the studied area on the chemical composition of all analyzed species. The nutrient content found in the dry matter (DM) and the digestibility of the pool of...

Bromeliad ornamental species: conservation issues and challenges related to commercialization - doi: 10.4025/actascibiolsci.v34i1.7314
Provedor de dados: 3
Autores: Negrelle, Raquel Rejane Bonato; Universidade Federal do Paraná - UFPR; Anacleto, Adilson; Faculdade do Litoral Paranaense; Mitchell, Darcy; Royal Roads University.
Bromeliads grow almost exclusively in the New World tropics and subtropics, mainly in South America in the Brazilian Atlantic Forest (ca. 1200 species). Within the last few decades, their beautiful shapes and colors, low maintenance and easy adaptability to small gardens have brought bromeliads into worldwide use as ornamental plants. While the ornamental bromeliad trade could make significant contributions to household economies in rural areas, the trade may represent a significant threat in some of the bromeliad biodiversity hotspot countries such as Brazil, Bolivia and Colombia. This paper presents an overview of production volumes, analysis of the Brazilian bromeliads trade chain – at the state, national and international levels – and recommendations...

Provedor de dados: 14
Autores: AMORIM, E. P.; SEREJO, J. A. dos S.; FERREIRA, C. F.; SILVA, S. de O. e.
The 'BRS Platina' variety is a tetraploid hybrid (AAAB) developed by Embrapa Mandioca e Fruticultura, located in Cruz das Almas, Bahia, Brazil, originated from the cross between the 'Prata Anã' (AAB) cultivar and the M53 (AA) diploid. It presents good tillering, average stature and development and yield characteristics identical to the 'Prata Anã'. The fruits are also similar to those of this cultivar in terms of shape, size and flavor; however, they should be consumed with greener peel, just as for the varieties of the Cavendish subgroup. It differentiates from 'Prata Anã' for being resistant to yellow Sigatoka and Fusarium wilt. Average yield is around 20 t hao1 per year. Under fertile soils, average yield can reach 40 t ha-1per year.

To determine the frequency of anti-Brucella canis antibodies in dogs attended in veterinary clinics from Patos, Paraíba State, Brazil, as well as to identify risk factors and to isolate and identify the agent, 193 dogs were used. Agar gel immunodiffusion test (AGID) was used to detect B. canis antibodies in sera. Isolation of B. canis was carried out in blood and bone marrow from seropositive animals. Six animals tested seropositive in AGID, resulting in a frequency of 3.11%. B. canis was isolated from bone marrow of one seropositive animal, with confirmation by PCR. Lack of cleaning of the dog's environment was identified as risk factor (odds ratio = 7.91). This is the first report of isolation of B. canis in dogs from the Northeast region of Brazil.

Bruguiera (Rhizophoraceae) in the Indo-West Pacific: a morphometric assessment of hybridization within single-flowered taxa
Provedor de dados: 16
Autores: Duke, N.C.; Ge, X.-J.
The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular...

BSE Disease Outbreaks, Structural Change and Market Power in the Canadian Beef Industry
Provedor de dados: 31
Autores: Clark,   J. Stephen; Cechura,   Lukas; Berhanu,   Adugna.
This study examines farm to wholesale prices spreads to measure the impact of the Bovine Spongiform Encephalopathy (BSE) disease outbreak on the Canadian beef industry. The study uses structure break tests developed by Gregory and Hansen (1996) and Hansen (1992) examine possible breaks within cointegrating relationships. The study finds evidence that the industry began a realignment as a result of the UK BSE disease outbreak, and the Canadian BSE disease outbreak was simply the largest realignment of the process beginning with the UK disease outbreak. However, the only statistically significant break was the BSE disease outbreak itself in May 2003. Stability was not restored until the border was reopened in 2005. Specific results indicated that the...

Autores: Araújo,Isabela M. S; Silva-Falcão,Elisabeth C; Severi,William.
The present study aims to compare the buccal apparatus and gastrointestinal tract of early life stages of Centropomus undecimalis (Bloch, 1792), and relate them to its diet. A total of 190 individuals collected with a channel net in the Catuama estuary (07º40'9.9''S, 34º50'36.7''W), northern coast of the state of Pernambuco, were examined. Morphometrical and meristic data were analyzed for the two initial developmental periods (larval and juvenile). Their digestive tube was morphologically characterized and its content identified. The longest transverse axis of food items was measured, and compared to the standard length (SL) and mouth gape size (D) of the individuals. Body measurement regressions differed significantly (p&lt;0.001) between larvae and...

Building of the Amsterdam-Saint Paul plateau: A 10 Myr history of a ridge-hot spot interaction and variations in the strength of the hot spot source
Provedor de dados: 5
Autores: Maia, Marcia; Pessanha, Ivo; Courreges, Esther; Patriat, Martin; Gente, Pascal; Hemond, Christophe; Janin, Myriam; Johnson, Kevin; Roest, Walter; Royer, Jean-yves; Vatteville, Judith.
The Amsterdam-Saint Paul plateau results from a 10 Myr interaction between the South East Indian Ridge and the Amsterdam-Saint Paul hot spot. During this period of time, the structure of the plateau changed as a consequence of changes in both the ridge-hot spot relative distance and in the strength of the hot spot source. The joint analysis of gravity-derived crust thickness and bathymetry reveals that the plateau started to form at similar to 10 Ma by an increase of the crustal production at the ridge axis, due to the nearby hot spot. This phase, which lasted 3-4 Myr, corresponds to a period of a strong hot spot source, maybe due to a high temperature or material flux, and decreasing ridge-hot spot distance. A second phase, between similar to 6 and...

Autores: Böhm, Herwart; Buchecker, Kirsten; Dresow, Jana; Dreyer, Wilfried; Landzettel, Christian; Mahnke-Plesker, Sylvia.
In den Jahren 2007 bis 2009 wurde der Kartoffelanbau auf 270 ökologisch bewirtschafteten Kartoffelfeldern, auf denen die 3 fest kochenden Kartoffelsorten Princess, Nicola und Ditta angebaut wurden, in Nord- und Süddeutschland untersucht. Hierzu wurden Anbau- und Qualitätsdaten erhoben und in eine Web basierte Datenbank eingespeist. An Ernteproben wurden Bonituren auf die äußeren Qualitätsmerkmale durchgeführt und die Stärke- und Nitratgehalte sowie die sensorische Qualität gemessen. Die unterschiedlich hohen Nitrat- und Stärkegehalte konnten dabei oftmals auf die Länge der Wachstumsperiode und damit auf das Auftreten von Phytophthora infestans zurückgeführt werden. Die sensorische Analyse zeigte für die 3 Sorten unterschiedliche sensorische Profile, wobei...

Burseramyia braziliensis, a new species of gall midge (Diptera, Cecidomyiidae, Asphondyliini) associated with Swartzia langsdorffii Raddi (Fabaceae)
Provedor de dados: 49
Autores: Maia,Valéria Cid; Fonseca,Karina Figueiredo.
Burseramyia braziliensis Maia &amp;amp; Fonseca, a new species of Cecidomyiidae (Diptera) that induces leaf galls on Swartzia langsdorffii Raddi (Fabaceae) is described and illustrated (larva, pupa, male and female) based on material from restinga areas of Bertioga, São Paulo, Brazil. Until now, Burseramyia was known from one galling species, Burseramyia burserae Möhn, 1960, restricted to El Salvador. The genus is easily recognizable by the shape of the gonostylus (equally subdivided into toothed and setose portions). The new species differs from the previously described species mainly in the number and shape of terminal papillae (larva), shape of hypropoct (male) and method of pupation.

Business Establishment Growth in the Appalachian Region, 2000-2007:  An Application of Smooth Transition Spatial Process Models
Provedor de dados: 31
Autores: Xu,   Wan; Lambert,   Dayton M.
Business establishment growth in the Appalachian region (2000–2007) was regressed on industry sector composition controlling for demographic, physical, and economic determinants. We test the hypothesis that local response to growth determinants is geographically heterogeneous using Smooth Transition spatial process models. This class of models exhibiting endogenous regime switching behavior provides another tool for exploring the spatially heterogeneous effects of local determinants on economic growth.

Buyer Alliances as Countervailing Power in WIC Infant-Formula Auctions
Provedor de dados: 31
Autores: Davis,   David E.
State WIC agencies in infant-formula procurement auctions receive lower bids and final prices when they are in buyer’s alliances than when they are unallied. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) uses an auction to procure infant formula. Manufacturers bid on the right to be an agency’s sole supplier by offering a rebate on formula sold through WIC. A theoretical model of rebates shows that bidders may shade their bids and extract surplus from agencies. An empirical estimation shows that bids are lower to alliances suggesting that alliances countervail the power of bidders to extract surplus.

Autores: Ferreira,Elizabeth; Toledo,Joice H. de; Dantas,Antonio A. A.; Pereira,Rafael M.
Medium-resolution satellite images have been widely used for the identification and quantification of irrigated areas by center pivot. These areas, which present predominantly circular forms, can be easily identified by visual analyses of these images. In addition to identifying and quantifying areas irrigated by center pivot, other information that is associated to these areas is fundamental for producing cadastral maps. The goal of this work was to generate cadastral mapping of areas irrigated by center pivots in the State of Minas Gerais, Brazil, with the purpose of supplying information on irrigated agriculture. Using the satellite CBERS2B/CCD, images were used to identify and quantify irrigated areas and then associate these areas with a database...

Autores: Chaves,Lúcia Helena Garófalo; Tit,Gilvanise Alves.
Reactions of heavy metals with clay minerals are important in determining metal fates in the environment. However, the adsorption process of these metals by the bentonite has been extensively investigated. The objectives of this work were to assess the ability of bentonite clay to adsorb cadmium and copper and to study the effects of pH and particle size upon these metals adsorption. Adsorption isotherms were obtained from batch adsorption experiments, with increasing cadmium and copper concentrations (5-200 mg L-1). To find out the effects of pH and particle size on adsorption, the experiments were conducted at pH 4; 5 and 6 using particles sizes of &lt; 0.5 mm and 0.5 to 2.0 mm . The difference between initial and final cadmium and copper concentrations...

Cadmium-induced oxidative stress and antioxidative enzyme response in water hyacinth and salvinia
Provedor de dados: 61
Autores: Vestena,Silvane; Cambraia,Jose; Ribeiro,Cleberson; Oliveira,Juraci A.; Oliva,Marco A.
The reactive oxygen species generation, lipid peroxidation and antioxidative enzyme response of water hyacinth and salvinia to Cd were evaluated. Cadmium was absorbed/accumulated mainly in the roots, but significant amounts also translocated to the leaves. No Cd effect on dry weight was detected, although toxicity symptoms were visible. Superoxide and H2O2 concentrations increased, in addition to lipid peroxidation in both species, especially in the leaves of salvinia. In general, antioxidative enzyme activities were reduced in both species following Cd treatment, especially in salvinia. Glutathione peroxidase (GPX, EC 1.11.1.9) activity decreased in water hyacinth but increased in salvinia. Glutathione S-transferase (GST, EC 2.5.1.18) activity increased...

Objetivou-se avaliar os efeitos da aplicação de calcário e boro nos atributos químicos de um Latossolo, estado nutricional e produtividade da cultura do feijoeiro. As doses de calcário empregadas foram crescentes, considerando-se a saturação por bases igual a 70%, correspondendo às doses: zero; 0,6; 1,2 (v = 70%); 1,8 e 2,4 t ha-1. O calcário utilizado apresentava poder relativo de neutralização total (PRNT), poder de neutralização (PN) e reatividade (RE) de 131; 137 e 95%, respectivamente. As doses de boro estudadas foram iguais a 0 (zero); 0,6; 1,2; 1,8; e 2,4 mg dm-3 de B, sendo a referência para definição das mesmas a de 1,2 mg dm-3 de B (ou 1,2 kg ha-1 de B). Utilizou-se como fonte o ácido bórico (H3BO3) p.a. (17% B). Na época do florescimento foi...

Autores: Auler,Pedro Antonio Martins; Neves,Carmen Silvia Vieira Janeiro; Fidalski,Jonez; Pavan,Marcos Antonio.
O objetivo deste trabalho foi avaliar o efeito da calagem e de porta-enxertos sobre a quantidade de raízes, a nutrição e a produção de laranjeira 'Valência', em diferentes sistemas de preparo do solo. O experimento foi instalado em blocos ao acaso, com parcelas subsubdivididas e três repetições. As parcelas consistiram de dois sistemas de preparo do solo: convencional e com preparo mínimo. As subparcelas consistiram de níveis de calagem: com ou sem. As subsubparcelas consitiram de três porta-enxertos: limoeiro 'Cravo' (Citrus limonia), tangerineira 'Cleópatra' (Citrus reshni) e Poncirus trifoliata. O tratamento com calagem recebeu 3 Mg ha-1 de calcário dolomítico, antes da implantação, e 1,65 Mg ha-1 quatro anos após o plantio. A produção foi avaliada...

Provedor de dados: 5
Autores: Sun, Hanjie; Li, Tiegang; Sun, Rongtao; Yu, Xinke; Chang, Fengming; Tang, Zheng.
Two sediment cores, MD06-3050 and MD06-3047, were analyzed to study the Quaternary calcareous nannofossil and microtektite records. We dated bioevents and the microtektite impact event by calibrating with oxygen isotope stratigraphy. Seven calcareous nannofossil bioevents were identified over the past 2.36 Ma including the last appearance of data for Discoaster brouweri, Calcidiscus macintyrei, large Gephyrocapsa and Pseudoemiliania lacunosa, the first appearance of data for large Gephyrocapsa and Emiliania huxleyi, and the abrupt increase in the abundance of Gephyrocapsa caribbeanica. In addition, we fortunately observed that Australasian microtektites were distributed in core MD06-3050 from 1340 to 1374 cm.

Marine mollusc shell growth has been widely measured using fluorochrome marking. In order to test the efficiency and reliability of calcein staining on P. margaritifera shells and pearls, the present study examined two administration methods, different concentrations and several immersion times.Immersion in a 150 mg.L-1 calcein solution for 12 h to 24 h appeared to be the best method for marking P. margaritifera shells. For pearl marking, injection of a 200 mg.L-1 calcein solution into the pearl pouch was the optimal method. Calcein marking was then used to measure the influence of food resource levels on the shell growth. Groups of 23-month-old P. margaritifera were fed at three trophic levels for two months. The two highest food levels tested (6 000...
