it is well established that the active continuous recovery is preferred to passive recovery. but the active period of this recovery is long (20-60 minutes) and the intensity is not controlled. furthermore, most severe trial exercises need short-term active recovery for better performance so that the athletes can return more rapidly to their normal state and more desirable performance. however, ...
Background and Aim: Blood donation causes changes in physical and physiological characteristics. The purpose of this study was to investigate the effects of blood donation on the exercise performance and some of hematologic parameters in physically active and non-active women. Materials and Methods: In this experimental study, 14 active women with history of physical exercises more than ...
colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. in this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (pbs) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. the pbs nanocrystals (qds) were synthesized in a non-coordinating solvent, 1-oc...
This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
