the aim of the present study was to investigate the manipulation of senses and speed on the performance of bimanual dynamic coordination. thus, 15 physical education students of shahid beheshti university with age range of 18-25 years performed in-phase and anti-phase patterns from slow to fast speed in five different sensory conditions. to investigate two motor patterns anova with repeated mea...
a high performance liquid chromatography method was studied for determination of 18 ?-glycyrrhetinic acid in glycyrrhiza glabra l. (licorice) extract. the operating condition were c-18 reversed phase column (vp-ods, (250×4.6 mm, 5 mm)) at room temperature, acetonitril/phosphoric acid (3/1) as mobile phase, at flow rate of 0.6ml/min (0-8min), 0.4ml/min (8-20min) and uv detection at 230 nm. the r...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
the purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor kr) groups. they practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respec...
