The local projection method is applied to inf-sup stable discretisations of the Oseen problem. Error bounds of order r are proven for known inf-sup stable pairs of finite element spaces which approximate velocity and pressure by elements of order r and r− 1, respectively. In case of a positive reaction coefficient, the error constants are robust with respect to the viscosity but depend on the p...

We further develop the general theory of the area reactivity model that provides an alternative description of the diffusion-influenced reaction of an isolated receptor-ligand pair in terms of a generalized Feynman-Kac equation. We analyze both the irreversible and reversible reaction and derive the equation of motion for the survival and separation probability. Furthermore, we discuss the noti...

Over recent years, the high levels of air pollution have become a quite important problem due to their direct impact on human health. Due to these health risks, EU directive (2008/50/EC) recommends member states to ensure that timely information about actual and forecasted levels of pollutants are provided to the public. In order to follow these guidelines, prevent critical episodes and inform ...

purpose the aim of this study was to determine the effect of one night's sleep deprivation on anaerobic performance and reaction time of subjects in the morning of the following day. methods eighteen male college student athletes were studied twice in a balanced, randomized design. subjects were measured for peak power, mean power and reaction time. results the performance showed no significant...
