Many marine ecosystems are under increasing pressure from multiple stressors. In the Baltic Sea, these stressors include oil and chemical spills from shipping, nutrient run-off from land and the introduction of non-indigenous species. All of these pressures have been growing over recent years. Increasing pressures lead to reductions in environmental quality, which produce negative effects on hu...

Quantum theory grew out based on experiments and radical theoretical proposals that were not based on accepted classical physics. In this new approach emerge nanostructures such as quantum wells, wires and dots in which electrons or holes are confined to an ultra-small region. The application of this nanostructures are still mostly confined to research laboratories, but they are remarkable and ...

Wellcome exists to improve health for everyone by helping great ideas to thrive. We are a global charitable foundation, both politically and financially independent. We support scientists and researchers take on big problems, fuel imaginations and spark debate. The health of the global population and the planet are inextricably linked but there is a poor ecological fit between what we are askin...

In this paper, we address the question of the hyperbolicity and the local wellposedness of the multi-layer shallow water model, with free surface, in two dimensions. We first provide a general criterion that proves the symmetrizability of this model, which implies hyperbolicity and local well-posedness in Hs(R2), with s > 2. Then, we analyze rigorously the eigenstructure associated to this mode...

Recent research suggests that establishing water clubs in care homes can counteract the dangers of dehydration and enhance residents' health and well-being. This study provided an experimental test of this idea, and also explored the possibility that it is the social interaction that clubs provide which delivers health-related benefits. Consistent with this hypothesis, the study found no eviden...
