The present work gives an insight into the internal heat management system of the terrestrial snail Xeropicta derbentina, which has to cope with extreme climate conditions in its habitat. The oxygen consumption of inactive ...
In this work we study the classical heat equation in $R^n$ if the initial data is given by the characteristic function $1_D$ of a compact set $D$ in $R^n$. Physically this means that at the beginning of the evolution we ...
