Objetivo: Este trabalho tem como objetivo, testar e comparar três técnicas coproparasitológicas para o diagnóstico de parasitos intestinais de seres humanos. Métodos: Foram realizadas 141 análises de amostras fecais de pessoas com variadas idades, utilizando três metodologias: método de Hoffman, Pons e Janer-adaptado por Katagiri S e Oliveira-sequeira TCG (2007), método de Willis-Mollay (1921) e a técnica de Gordon e Whitlock-modificada (ou OPG). Resultados: A prevalência de helmintíases utilizando o método de Hoffman, Pons e Janer-adaptado foi de 14,18% (20), para o método de Willis-Mollay foi de 15,32% (19) e para a técnica de OPG foi de 12,94% (15). Conclusão: Os resultados mostraram que o método de Willis-Mollay recuperou um número maior de gêneros de parasitos instestinais e demonstrou ser mais rápido e de fácil execução. E com a realização das três metodologias, pode-se observar que as espécies de Ascaris lumbricoides e Trichuris trichiura foram às de maior prevalência neste estudo.
The infiltration of water in the floodplain of the Paraíba do Sul river is a natural mechanism that promotes the conservation of the hydrographic basin water resources by decreasing the loss of water by runoff or evaporation. The two main economic activities developed in the floodplain of the Paraíba do Sul river are irrigated rice crop and sand mining. Both cause great loss of surface water by evaporation due to large plots of rice and abandoned sand mining pits filled with water. This research aimed to investigate water infiltration into the soil covered with different cover types in the floodplain of the Paraíso sand extraction port, Tremembé municipality, Paraíba do Sul river basin. Five infiltration tests were conducted in the area, including: close to the rice plot, abandoned and operational port sand sites. In general, the soil had low permeability and the infiltration velocity was practically insignificant. However, in the area of natural forest and pasture vegetation the permeability was higher than in the rice and sand pits.
O artigo objetiva apontar alguns limites quanto ao uso da noção de “necropolítica” no tocante à leitura da letalidade violenta. Como referência para análise, proponho analisar o problema das mortes ocasionadas por intervenção policial em duas escalas: uma local, referente a um “caso” ocorrido no Morro da Providência; outra mais ampla, que diz respeito à lógica espacial das mortes ocasionadas pela polícia na metrópole carioca. Defendo a ideia de que tal problema possui particularidades no Rio de Janeiro, não sendo possível universalizar os significados da morte quando pensamos na chave específica das ações letais praticadas pelo Estado.

Soybean (Glycine max) is a crop of high economic power in the world, being used to produce vegetable oil, as well as a source of food for animals and humans. Recent research indicates that nutrient application in the seed stage contributes to the early and productive development of crops. Since silicon (Si), as a nutrient for plants, acts in the cellular structure and the formation and performance of plant architecture, the aim of this study was to evaluate the influence of silicon application via seeds on the initial growth of three soybean cultivars. The experimental design was a randomized block. The treatments were replicated three times and distributed in a 3×5 factorial scheme, composed by three soybean cultivars (C1 - FTR 1186 IPRO, C2 - FTR 1192 IPRO and C3 - FTR 3190 IPRO) and five silicon doses (0, 30, 60, 90 and 120 g per 100 kg of seeds). The data were submitted to ANOVA by F-test and polynomial regression analysis for the silicon doses; the cultivars response was evaluated through the Tukey mean test. The treatment of soybean seeds with silicon did not positively influence the root dry mass of the FTR 1192 IPRO, nor the root length and root diameter of the FTR 1186 IPRO. The application of silicon did not influence the FTR 3190 IPRO.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
