✦ Synopsis

To set granular media in motion inter particular-forces have to be overcome. A discrete particle-particle model was used to calculate the torque in a two blade solid stirrer. In the context of a qualitative parameter study the influence of damping coefficient c, Young's Modulus E, number of particles n and the iteration time t on the moment was studied. The experimental data with glass spheres agrees satisfactorily with the model values.

## Abstract This article deals with the impact of water content of solid waste on biogas production kinetics in landfills. This impact has been proved in the laboratory thanks to anaerobic biodegradation experiments on paper/cardboard waste samples. A strong dependence with the moisture level was o

This paper presents a general framework for the formulation of constitutive models that incorporate a localized dissipative mechanism. The formalism of strong discontinuities is employed, allowing for the decoupling of the constitutive characterization of the continuum and localized responses of the
