The long term response of surface waters to changes in sulphur deposition and afforestation is investigated for three upland river systems in the Galloway region of south-west Scotland.From 1984-1999, these rivers exhibited a statistically significant decline in non-marine sulphate concentrations in response to reduced acid deposition.This reductio

In this work, some phenomenological growth models based only on the population information (macroscopic level) are deduced in an intuitive way.These models, for instance Verhulst, Gompertz and Bertalanffy-Richards models, are introduced in such a way that all the parameters involved have a physical interpretation.A model based on the interaction Ho
Abstract Background Given the importance of inflammation as a predictor of poor outcomes in End Stage Renal Disease (ESRD), reductions in inflammatory biomarkers have been proposed as a critical target in this population.This study targets chronic periodontitis, an oral inflammatory disease of microbial etiology causing persistent inflammation in E
