O síndrome da morte súbita, inesperada e inexplicada do lactente (MSIL) ocorre normalmente entre 1M e 1 A de vida, com um máximo entre os 2 e os 4M, constituindo a principal causa de morte pós-neonatal nos países desenvolvidos.A MSIL ocorre quase sempre no domicílio e constitui em geral um achado isolado numa família, embora ocasionalmente se repita em irmãos. Em Portugal foi já observada uma família com 6 caso...
Animal performance is affected by high air temperature and it is known that shade reduces the absorption of radiant temperature, and water for immersion facilitates heat loss. This study intends to find preferences of resources that contribute for the well-being of cattle and how they alterdaily behaviour. During summer, six Caracu and six Red Angus bulls were submitted to two different treatments: availability...
Objectives: Access to evaporative cooling system can increase production in dairy cows due to improve thermal comfort. The aim of this study was to evaluate the impact of ambient temperature on thermoregulation, cortisol and IGF-I, and determine the efficiency of evaporative cooling system on the physiological responses in different weather patterns. Materials and Methods: 24 Holstein cows were housed in two gr...
The shade is an important resource in the extensive production systems in tropical regions. The aim of this study is to understand through behavioral analysis, the preferences of animals for resources for environmental protection. The experiment was conducted in the Biometeorology and Ethology Laboratory of FZEA-USP. Six male of Caracu and Red Angus cattle breeds were used. The animals were submitted to 2 diffe...

Relataram-se dois casos em que a penectomia com transposição peniana perineal foram as técnicas cirúrgicas de escolha e que resultaram em 50% de sucesso. Quatro casos em que as cistotomias seguidas de cistostomias apresentaram 100% de sucesso, um caso em que só a cistotomia foi realizada e não se obteve sucesso, um caso em que apenas o tratamento clínico foi eficiente e dois casos em que houve 100% de insucesso...
Many approaches have been made during the past years to the gas sensing task. It may be addressed using one sensor or a set of arranged sensors. Solid state chemical sensing has been systematically used for the development of gas sensor devices, based on semi conducting metal oxides. There are three major issues related to chemical sensing: sensitivity, selectivity and stability. Selectivity may be improved by ...
