the aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). the training protocol was performed three sessions a week for 6 weeks. data analysis indicated a significant ...

the aim of the present study was to investigate the effect of contextual interference on balance of mentally retarded people. for this purpose, 40 educable and mentally retarded boys in qazvin city (mean age 24.45 ± 3.120) were randomly divided into two groups: blocked and random practice. after the pretest, given their practice arrangement, subjects in each group performed their workout for 4 ...

the purpose of present study was investigation of the effect of attentional focus of novice players’ self-statements in basketball free throw practice on their state anxiety in transfer test with spectators’ presence. therefore, 38 novice females (mean of the age=22 yrs.) who had intermediate trait anxiety were selected randomly by sports competitive anxiety test (scat). the participants were a...

the purpose of the present study was to investigate the effect of variability of attentional focus distance by self-talk on the learning of table tennis forehand in. after pretest, the participants performed 180 forehand strokes during 6 sessions with repeating the words “slightly rotation” in the internal focus group “slightly open” in the near external focus group, “over the net ” in the far ...

background: luteal phase support is mandatory in art (assisted reproductive technologies) for optimizing outcome, so the luteal phase is supported with either progesterone, addition of estradiol to progesterone, hcg or gonadotropin releasing hormone (gnrh) agonists. supplementation of luteal phase with progesterone is prescribed for women undergoing routine ivf treatment. objective: to compare ...

objective(s): the aim of this work was to investigate the effect of the natural and the chemically modified form of cyclodextrins namely; β-cyclodextrin (β-cd) and hydroxypropyl-β-cyclodextrin (hp-β-cd) respectively on the solubility and dissolution rate of aripiprazole; an antipsychotic medication showing poor aqueous solubility.   materials and methods: phase solubility of aripiprazole with t...

All Digital Phase locked loops (ADPLL) plays a major role in System on Chips (SoC). Many EDA tools are used to design such complicated ADPLLs. It operates on two modes such as frequency acquisition mode and phase acquisition mode. Frequency acquisition mode is faster compared to Phase acquisition, hence frequency synthesis is performed. The CMOS technology is used to design such a complex desig...

Many animal groups exhibit rapid, coordinated collective motion. Yet, the evolutionary forces that cause such collective responses to evolve are poorly understood. Here, we develop analytical methods and evolutionary simulations based on experimental data from schooling fish. We use these methods to investigate how populations evolve within unpredictable, time-varying resource environments. We ...
