Drawing on the theories of limit equilibrium and finite-element strength reduction, this paper explores instability modes stability change laws slope in zones E, W, S Jiajika spodumene mine, through rock mechanics tests, field survey, numerical simulation. The results show that sliding mode is circular arc or + plane sliding. Overall, final open-pit mine generally stable under current design, s...

We address the question of transport heat, in out-of-equilibrium systems. The experimental set-up consists two coupled granular gas Non-Equilibrium Steady State (NESS) heat baths, which Brownian-like rotors are imbedded. These electro-mechanically thanks to DC micro-motors, through a resistor $R$, such that energy flows between them. average flux depends linearly difference baths' temperature. ...
