We have performed a systematic, large-scale simulation study of granular media in two and three dimensions, investigating the rheology of cohesionless granular particles in inclined plane geometries, i.e., chute flows. We find that over a wide range of parameter space of interaction coefficients and inclination angles, a steady-state flow regime exists in which the energy input from gravity bal...

We present fully nonlinear time-dependent simulations of a thin liquid film flowing down an inclined plane. Within the lubrication approximation, and assuming complete wetting, we find that varying the inclination angle considerably modifies the shape of the emerging patterns: Finger-shaped patterns result for the flow down a vertical plane, while saw-tooth patterns develop for the flows down a...

In inclined U-notches, the mixed mode (I + II) loading occurs and the mode ratio can be increased by varying the notch angle. In this paper, the effect of the inclined U-notch geometry, i.e. the notch depth, the notch angle, the notch root radius, and the position of the notch with respect to supports, on the mode ratio (KII/KI) have been studied. Three-point bending and plane strain condition ...

The future of muscle weakness is frequently observed in cerebral ischemia, and a common complaint in human. So the animal test for the pathophysiology study and development of drug therapies is necessary. Various methods have been developed and widely used to examine muscle strength in motor performance. In animal model, most of these methods were observed by observers, and they converted the r...

We present two 2-dimensional approaches to studying the properties of a ball moving down a rough inclined plane (a 3 dimensional system). The rst is a molecular dynamics simulation which has exposed several interesting characteristics of the two dimensional system that are absent in three dimensions. The second is a simpliied stochastic model based on the equations of motion. This model faithfu...

Introduction: resent studies have been shown that normobaric hyperoxia (HO) can induce excitotoxicity and stress oxidative tolerance (ETT) in variety of organs such as brain. In this study, we examined the intermittent dose of normobaric hyperoxia (HO) on neurologic deficit, and superoxide dismutase activity in brain tissue of Huntington animal model. Method: The rats were divided to three...
