The Einstein-Straus model consists of a Schwarzschild spherical vacuole in a Friedman-Lema^ tre-Robertson-Walker (FLRW) dust spacetime (with or without ). It constitutes the most widely accepted model to answer the question of the in uence of large scale (cosmological) dynamics on local systems. The conclusion drawn by the model is that there is no in uence from the cosmic background, since the spher- ical vac...
We apply the SIR model to study the evolution of Measles and Hepatitis C in Portugal using data from 1996 until 2007. Our results are potentially interesting to forecast the evolution of those viruses in subsequent years.
O presente trabalho investigou as propriedades antinociceptiva, antiinflamatória e antiulcerogênica do extrato etanólico dos galhos de E. erythropappus. Foram realizados os testes de contorções abdominais induzidas por ácido acético; tempo da lambida da pata induzida por formalina; placa quente; edema de pata induzido por carragenina; lesões ulcerativas induzidas por indometacina e etanol. As doses de 50, 100 e...
