Many alpine torrents convey regularly debris flows of high destructive hazard. After several granular events observed in Bruchji’s torrent near the Blatten village in the Swiss Alps, it was decided to manage the risk of similar debris flows by designing and constructing a control structure inside the torrent bed. Associated with a breach in the right bank side of the torrent, this control struc...

The IP3R calcium release channel has been simulated using a stochastic simulation algorithm (SSA;Gillespie algorithm) and De young-Keiser model. A set of different concentration for Cat' and IP3 havebeen used. Considering the Number of molecules in each state, a non linear behavior of the system can beseen clearly. The inhibiting role of the Ca+2 on the open state (X110) has been studied. The d...

Introduction: we have recently reported the presence of two potassium currents with 598 and 368 pS conductance in the rough endoplasmic reticulum (RER) membrane. The 598 pS channel was voltage dependent and ATP sensitive. However, the 368 pS channel was rarely observed and its identity remained obscure. Since cationic channels in intracellular organelles such as mitochondria and RER play imp...
