Means of cutting down cost feed resources in order to bridge the wide gap between demand and supply animal protein livestock production is a great concern poultry industry. This study was conducted investigate effect feeding diets containing soaked fermented Baobab seed meal (BSM) on growth performance broiler starter chicks. A total 150, one-day old chicks were randomly distributed into five t...

In this paper we describe a new approach for the detection of fine structures in an image. This approach is based on the computation of the topological gradient associated to a cost function defined from a regularization of the data (possibly noisy). We get this approximation by solving a fourth order PDE. The study of the topological sensitivity is made both in the cases of a circular inclusio...

We review twentieth century and projected twenty-first century changes in climatic and hydrologic conditions in the northeastern United States and the implications of these changes for forest ecosystems. Climate warming and increases in precipitation and associated changes in snow and hydrologic regimes have been observed over the last century, with the most pronounced changes occurring since 1...

Setting up generic and fully transparent distributed services for clusters implies complex and tedious kernel developments. More flexible approaches such as user-space libraries are usually preferred with the drawback of requiring application recompilation. A second approach consists in using specific kernel modules (such as FUSE in Gnu/Linux system) to transfer kernel complexity into user spac...

Background: The rising global emergence of Gram-negative bacteria (GNB) producing ?-lactam hydrolysing enzymes in clinical infections constitutes a growing public health threat. This study investigated the occurrence co-production extended spectrum ?-lactamase (ES?L), AmpC ?-lactamases, and carbapenemases among GNB isolated from HIVinfected patients two tertiary healthcare facilities southwest ...
