Aimed to study the relationship between scrotal temperature on semen quality by use of infrared thermography in Nelore bulls bred extensively. There were scrotal thermography and semen collection. Climatic data were collected by means of globe thermometer. The thermograms of the scrotum were obtained by digital infrared thermography. We carried out ejaculates through electroejaculation for analysis of quantitative and qualitative characteristics. For the data, we used analysis of variance and subsequently applied the Tukey test at 5%. (p <0.05) between animals for sperm vigor, sperm motility between animals and between crops, sperm concentration, total sperm and total viable sperm between groups, between harvests for the scrotum temperatures and climate data. It was concluded that the surface temperatures of the scrotum and climatic factors influence the quality of semen. Thermography is recommended as a complementary test in the evaluation of reproductive bulls.

The objective of this work was to evaluate the sediment production in the initial part of the Pardo River Basin - Botucatu/SP from 1994 to 1999, using the mathematical hydrological model SWAT. It was used topographic maps and satellite data manipulated in GIS using the software SPRING 5.1.6. The simulation of sediment production was generated with the aid of an interface between the hydrological model SWAT 2009 with ArcView ®, version 9.3. The maps of Soil, Land Use and Digital Elevation Model (DEM) were generated in the GIS-SPRING 5.1.6 and exported to ArcSWAT 2009. The tabular data related to the parameters of soil and meteorological parameters were entered directly to the SWAT. The model allowed to estimate the sediment production. A sediment average production rate of 33.866 ton ha-1 over the six years of study was computed in the point of discharge of the basin.

The aim of this work is to discriminate vegetation classes throught remote sensing images from the satellite CBERS-2, related to winter and summer seasons in the Campos Gerais region Paraná State, Brazil. The vegetation cover of the region presents different kinds of vegetations: summer and winter cultures, reforestation areas, natural areas and pasture. Supervised classification techniques like Maximum Likelihood Classifier (MLC) and Decision Tree were evaluated, considering a set of attributes from images, composed by bands of the CCD sensor (1, 2, 3, 4), vegetation indices (CTVI, DVI, GEMI, NDVI, SR, SAVI, TVI), mixture models (soil, shadow, vegetation) and the two first main components. The evaluation of the classifications accuracy was made using the classification error matrix and the kappa coefficient. It was defined a high discriminatory level during the classes definition, in order to allow separation of different kinds of winter and summer crops. The classification accuracy by decision tree was 94.5% and the kappa coefficient was 0.9389 for the scene 157/128. For the scene 158/127, the values were 88% and 0.8667, respectively. The classification accuracy by MLC was 84.86% and the kappa coefficient was 0.8099 for the scene 157/128. For the scene 158/127, the values were 77.90% and 0.7476, respectively. The results showed a better performance of the Decision Tree classifier than MLC, especially to the classes related to cultivated crops, indicating the use of the Decision Tree classifier to the vegetation cover mapping including different kinds of crops.

A qualidade de vida para o ser humano depende do resultado das relações entre os processos biológicos, ecológicos, culturais e socioeconômicos que acontecem no espaço. Assim, a preocupação com a influência de zonas urbanas sobre o meio ambiente e a população tem sido um tema de crescente importância no Brasil, associando o desenvolvimento de novas políticas de gestão e reestruturação de grandes cidades. Nessa discussão, incluiu-se a questão da transformação da paisagem em ambientes urbanos, com impacto na manutenção dos serviços ecossistêmicos e na qualidade de vida da população humana. Este estudo propôs a caracterização da evolução da cobertura e uso do solo para a cidade de Carapicuíba, na Grande São Paulo, através da elaboração de seis mapas temáticos de uso e ocupação do solo do município, entre o período de 1962 e 2013. Além disso o projeto também pretendia fazer a modelagem de cenários futuros de mudanças, através de uma abordagem baseada no uso integrado de sensoriamento remoto, sistema de informações geográficas e modelos espaciais dinâmicos. Os mapas temáticos foram elaborados através de três mosaicos de fotografias aéreas adquiridas em 1962, 1972 e 1994, uma imagem orbital do sensor Ikonos de 2002, um mosaico de ortofotos aéreas adquirido em 2008, e uma imagem do sistema orbital RapidEye adquirida em 2013, para avaliação da dinâmica de ocupação da superfície da terra. As datas de imageamento disponíveis conseguiram representar momentos diferentes na história do município, referentes a acontecimentos importantes e que influenciaram significativamente na alteração da paisagem urbana: o grande crescimento demográfico e a construção das vias de acesso a Carapicuíba. As análises de dados e discussões apontam que o tipo de via de acesso à Carapicuíba e o tipo de uso do solo urbano, influenciaram na estratificação socioeconômica e na conservação de cobertura vegetal...
