Substance flows through environment and society, the equilibrium — time interaction of the ecosystem. Analysis of such differences has equal validity in drawing lessons for materials use in human societies as the recognition of the broader generalisations

Ernst Ulrich Von Weizsäckersystem of mixed sign under periodic boundary conditions are performed using a fast special-purpose computer for molecular dynamics (GRAPE9). Clustering of point vortices of like sign is observed and a columnar dipole structure appears as an equilibrium state. These numerical results are explained fr

Helias Udo De Haes,Gjalt Huppes,Geert De Snoowater jet is investigated by experimental observation and numerical simulations. Using a high-speed video camera with a frame rate of approximately . fps, it is found that high-pressure pulses are formed by collapsing bubble clouds, and that those pulses rise at a few microseconds before the cloud c
