Background: Aerobic exercise with Blood Flow Restriction (BFR) plays an important role in skeletal muscle adaptation; however, the effects of this type of exercise on mitochondrial dynamics proteins are unclear. Objective: The purpose of this study was to investigate the effect of aerobic exercise with and without BFR on mitochondrial dynamics proteins of human skeletal muscles.  Methods: Pa...

conjugated polymer actuators can be employed to achieve micro and nano scale precision, and have a wide range of applications including biomimetic robots, and biomedical devices. in comparison to robotic joints, they do not have friction or backlash, but on the other hand, they have complicated electro-chemo-mechanical dynamics which makes modelling and control of the actuator really difficult....

many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

Molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of Kob-Anderson binary Lennard-Jones (BLJ) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. The presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...

اگرچه زمینه های تفکر و نگرش سیستمی را می توان در آثار دانشمندان قدیم یافت ، اما ورود جدی آن به عرصه عملی و کاربردی عمدتاً به دوران معاصر باز می گردد . یکی از جالبترین موارد کاربرد نگرش سیستمی ، ایجاد رشته جدیدی به نام پویایی سیستم ( system Dynamics) است . پس از انتشار کتاب پویایی صنعتی (Industrial Dynamics) در سال 1961 ، توسط جی . دبیلو فارستر (Jay. W. Forrester) مطالعات پویایی سیتم در زمینه های...
