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...

Multi-echo Dixon VIBE contained in LiverLab provides liver fat fraction values which are corrected for the effects of transversal relaxation. By doing this, it also provides a simultaneous estimation of that transversal relaxation time T2*, which is corrected for fat signal effects, herefafter called T2c*. The reciprocal value of this estimate, fat-corrected R2c* = 1/ T2c*, can be used, within ...

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 article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

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...
