Influence of disordered porous media in the anomalous properties of a simple water model

The thermodynamic, dynamic and structural behavior of a water-like system confined in a matrix is analyzed for increasing confining geometries. The liquid is modeled by a two dimensional associating lattice gas model that exhibits density and diffusion anomalies, in similarity to the anomalies present in liquid water. The matrix is a triangular lattice in which fixed obstacles impose restrictions to the occupation of the particles. We show that obstacules shortens all lines, including the phase coexistence, the critical and the anomalous lines. The inclusion of a very dense matrix not only suppress the anomalies but also the liquid-liquid critical point

Melhoramento do gado Canchim.

Este subprojeto consta de três experimentos que tem como objetivos: Avaliar a produtividade do rebanho Canchim da UEPAE/São Carlos no período de 1953 a 1976; estimar parâmetros genético em bovinos da raça Canchim; construir um índice de seleção que, após testado, possa ser utilizado pelos criadores de Canchim
