Abstract The relaxation time approximation (RTA) is a well known method of describing the evolution statistical ensemble by linking distributions variables interest at different stages their temporal evolution. We show that if all occurring in RTA have same functional form quasi-power Tsallis distribution which depends on its control parameter, nonextensivity q ( t ), then it more convenient to...

the hypotensive effect of garlic has been well-documented in human subjects and animals. since endothelial activity regulates vascular reactivity in physiological and pathophysiological conditions, the aim of the present study was to investigate the effect of garlic on endothelium-dependent and independent relaxation of rat aorta for elucidation of mechanism of the garlic anti-hypertensive effe...

In this study, for the first time, a comparison of single-relaxation-time, multi-relaxation-time and entropic lattice Boltzmann methods on non-uniform meshes is performed and application of these methods for simulation of two-dimensional cavity flows, channel flows and channel flows with sudden expansion is studied in the slip and near transition regimes. In this work, Taylor series expansion a...

background: fatigue is one of the important factors in nursing performance because it affects the quality of care provided to the patients. in this regard, some complementary interventions such as benson relaxation techniques may relieve fatigue. this study aimed to evaluate the effect of benson relaxation on fatigue of nurses working in intensive care units. methods: this is an experimental st...

The analytic center cutting plane method (ACCPM) is one of successful methods to solve nondifferentiable optimization problems. In this paper ACCPM is used for the first time in the vehicle routing problem with time windows (VRPTW) to accelerate lagrangian relaxation procedure for the problem. At first the basic cutting plane algorithm and its relationship with column generation method is clari...
