Soroprevalência da arterite viral equina em mesorregiões paulistas entre 2007 e 2008

This study investigated the occurrence of equine arteritis virus antibodies using neutralization test in 1,400 horses from Campinas and macro metropolitan paulista mesoregions located at São Paulo State, between 2007 and 2008. Eighty (5.7%) samples showed antibodies to virus (titers from 4 to 4,096). Among the 42 cities, 15 (35.7%) presented at least one seropositive animal to equine arteritis virus. of the 238 farms analyzed 41 showed at least one seropositive animal. The occurrence was higher in sport horses like jumping horses, Quarter horses and was similar for female and male. The rate of seropositive was higher in animals older than 24 months of age. These results suggest the virus circulation among horse population in studied farms, and the need for continuing epidemiological surveillance studies.

Microstructural and optical characterization of CaWO4 and SrWO4 thin films prepared by a chemical solution method

Stoichiometric CaWO4 and SrWO4 thin films were synthesized using a chemical solution processing, the so-called polymeric precursor method. In this soft chemical method, soluble precursors such as strontium carbonate, calcium carbonate and tungstic acid, as starting materials, were mixed in an aqueous solution. The thin films were deposited on glass substrates by means of the spinning technique. The surface morphology and crystal structure of the thin films were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Nucleation stages and surface morphology evolution of the thin films on glass substrates were studied by atomic force microscopy. The films nucleate at 300 degreesC, after the coalescence of small nuclei into larger grains yielding a homogeneous dense surface. XRD characterization of these films showed that the CaWO4 and SrWO4 phases crystallize at 400 degreesC from an inorganic amorphous phase. No intermediate crystalline phase was identified. The optical properties were also studied. It was found that CaWO4 and SrWO4 thin films have an optical band gap, E-gap=5.27 and 5.78 eV, respectively, of a direct transition nature. The excellent microstructural quality and chemical homogeneity confirmed that this soft solution processing provides an inexpensive and environmentally friendly route for the preparation of CaWO4 and SrWO4 thin films.

Marine Protected Areas in Brazil: An ecological approach regarding the large marine ecosystems

The objective of this study was to address the importance of implementing Coastal and Marine Protected Areas in Brazil and to examine their distribution, based on the delimitation of Large Marine Ecosystems. Out of a total of 336 protected areas identified in Brazilian coastal and marine areas, the North Platform has the largest protected area, but the ecosystem with the largest number of protected area, predominantly sustainable areas, was the East Coast followed by the South Platform. One of the reasons the eastern coast of Brazil to have more protected areas is the fact that there is a largest amount of coral reefs. Additionally there was political opportunities for the creation of protected areas for sustainable use. The coastal region of Brazil has achieved the goal proposed by the Seventh Conference of the Parties to the Convention on Biological Diversity - 7, but only then through the category V of the International Union for Conservation of Nature, which is not the best efficient means of conserving resources. The goal for marine conservation shows only the area above the recommended under protection in North Platform. The Marine portion of the East Coast and the South Platform has few protected areas, regardless of category management. We consider the coastal region the range of 12 nautical miles from baselines determined in accordance with the United Nations Convention on the Law of the Sea. As for the number of strategies permitted by law and used for the conservation of coastal and marine systems, coastal systems show a higher number when compared with the marine system. We suggest that the Brazilian government should specify strategies for the protection of marine systems and expand the protected areas of all Large Marine Ecosystems. © 2013 Elsevier Ltd.

Energy and lysine for broilers from 44 to 55 days of age

An experiment was conducted to evaluate the performance and carcass yield of broilers at 55 days of age fed diets with different levels of metabolizable energy and lysine. Evaluated data of performance were weight gain, feed intake, energy intake, lysine intake, caloric conversion and feed conversion. Carcass assessment was performed based on data from carcass yield, breast weight, whole wings, whole legs, back, head + neck, feet and abdominal fat. A 3 x 3 factorial arrangement was used, with 3 levels of metabolizable energy (3,200; 3,400 and 3,600 kcal ME/kg) and 3 lysine levels (0.95%; 1.05% and 1.15%). There was no interaction between the two factors. Nevertheless, increasing levels of metabolizable energy improved weight gain (745 g; 841 g and 910 g, respectively) and feed intake was higher in broilers receiving the diets with 3,200 and 3,600 kcal ME/kg. Overall performance was not affected by lysine levels. Feed conversion values were 2.69, 2.42 and 2.14 for birds fed diets with 3,200; 3,400 and 3,600 kcal ME/kg, respectively. Carcass yield and breast weight increased with higher levels of energy and lysine in the diets.

Qualidade fisiológica de sementes de milho-doce BR 400 (bt) em função do teor de água na colheita e da temperatura de secagem

O objetivo deste estudo foi avaliar a qualidade fisiológica das sementes de milho-doce em função do teor de água na colheita e da temperatura de secagem em espiga. O experimento foi instalado na área experimental da FCA/Unesp, Botucatu-SP. Utilizou-se a cultivar BR 400 (bt) 'Super doce'. O delineamento experimental empregado foi o de blocos ao acaso com seis repetições, constituindo os tratamentos as épocas de colheitas. As colheitas das espigas foram iniciadas após a maturidade fisiológica; após despalhadas e divididas em duas porções, as espigas foram submetidas a secagem em estufas com circulação forçada nas temperaturas de 30 e 40ºC. Foi utilizada uma testemunha com sementes secadas no campo com 10,1% de teor de água. Foram determinados os teores de água das sementes, inicial e após a secagem, de todas as colheitas. Após a secagem, as espigas foram debulhadas manualmente, as sementes acondicionadas em saco de papel e armazenadas em condições ambientais de laboratório. As avaliações da qualidade fisiológica das sementes (emergência de plântulas no campo, índice de velocidade de emergência, matéria seca de plântulas, germinação, vigor-primeira contagem do teste de germinação, envelhecimento acelerado, teste de frio, condutividade elétrica e teores de Ca, Mg, K e Na lixiviados na solução do teste de condutividade elétrica) foram realizadas antes e após seis meses de armazenamento. As sementes de milho-doce cultivar BR 400 (bt), com teor de água igual ou menor do que 35%, podem ser submetidas à secagem em espiga a temperatura de 30 ou 40ºC, sem perdas significativas em sua qualidade fisiológica.

Effects of gamma-irradiation on caprolactam level from multilayer PA-6 films for food packaging: Development and validation of a gas chromatographic method

A gas chromatographic method to determine caprolactam in multilayer PA-6 films used for meat foodstuffs and cheese was developed and validated. A wide linear range (0.8-400 mu g/ml), RSD <= 4.1% and recovery higher than 90.0% were obtained for the chromatographic system, while precision and accuracy of the method showed RSD <= 3.8%, recovery from 95.5-100.0% and LOQ of 32 mu g/g. Irradiated (3, 7 and 12 kGy) and non-irradiated commercial films were analyzed. Most of them increased caprolactam levels with the increase of irradiation doses. (C) 2008 Elsevier Ltd.
