The objective of this work was to estimate the antioxidant capacity of some fruits extracts containing anthocyanins (strawberry, raspberry, elderberry, mulberry, blackberry, bilberry, black and red currant) using an electrochemical technique and three classical chemical methods based on reaction between antioxidants and a chromogen compound. evaluation of antioxidant activities of extracts was ...
here, the concept of electric capacity on finsler spaces is introduced and the fundamentalconformal invariant property is proved, i.e. the capacity of a compact set on a connected non-compact finslermanifold is conformal invariant. this work enables mathematicians and theoretical physicists to become morefamiliar with the global finsler geometry and one of its new applications.
Background and aims: Maximal oxygen uptake (VO2max) represents physical work capacity. Therefore in physically demanding jobs like firefighting, precise evaluation of employees' aerobic capacity is critical in order to ensure their physical capabilities and fitness for work duties. The aim of this study was to evaluate the maximal aerobic capacity and its associated factors in firefighters. ...
Introduction: Measurement of Maximum aerobic capacity (VO2-max) is important in physiologically fitting the workers to the job. The objective of this study was to investigate the effect of anthropometric and demographic factors on physical work capacity. Methods: Methods: In this study 60 students of Ahwaz University of Medical Sciences were selected voluntarily. A checklist consisted of two s...
musculoskeletal disorders have devoted a high percentage of occupational injuries and is one of the leading causes of occupational injuries and disabilities in industrialized and developing countries. the aims of this study were to evaluate exposure of musculoskeletal disorders risk factors by quick exposure check (qec) technique and to determine prevalence of musculoskeletal disorders and thei...
In this paper we evaluate the system performance and capacity of single carrier ultra-wideband (UWB) networks over 60GHz wireless personal area network (WPAN) channel. Symbol error rate is derived for both single user and multiple access scenario with a general system capacity and performance evaluation approach based on moment generation function. System outage probability and network throughp...
