introduction : cerebral autoregulation (ca) and mean cerebral blood flow velocity in males and females are still under controversy. the present study was scheduled to address the effect of sex on these parameters. materials and methods : the present study was interventional and performed on 30 healthy volunteers (15 males aging from 20-30 yrs and mean age of 23.9±3 years old and 15 females agin...

Flow-rate measurement in rivers under different conditions is required for river management purposes including water resources planning, pollution prevention, and flood control. This study proposed a new discharge estimation method by using a mean velocity derived from a 2D velocity distribution formula based on Tsallis entropy concept. This procedure is done based on several factors which refl...

the aim of this study was to assess the effect of external focus of attention instruction during walking training on old women’s gait kinematic parameters including stride length, velocity, variability of velocity, cadence and double support percent. for this purpose, 16 old women (mean age 69.8+4 years) were selected and randomly assigned to experimental and control groups (each group 8 subjec...
