Since there are variations in the reaction times of athletes in different sports, the aim of the present study was to evaluate the effectiveness of a specific training program on a simple reaction time of male gymnasts. In this longitudinal study, fourteen adolescent gymnasts (mean age 12.6 ± 2.1 years) were randomly selected to work out for 15 months in the artistic group. Simple reaction ti...
Introduction: Due to the increasing development of science and technology in today’s world and updates in organizational factors, staff development becomes more essential. An educational program could be considered effective if it could appropriately change in participants’ knowledge and behavior. The aim of this study is to assess the training course of working with ECT (DC Shock device) for n...
the kinetics and mechanism of the reaction between benzaldehyde 1, malononitrile 2 and dimedone 3 in a mixture of ethanol and water as solvents in the presence of fructose as a biodegradable catalyst has been studied by the spectroscopic method (uv-vis spectrophotometry method). the influence of various parameters (temperature, solvent and concentration) was studied on the reaction by means of ...
M\Iany workers have observed that various species of clostridia can use molecular oxygen as a hydrogen acceptor (Aubel and Houget, 1939; Bard, 1949; Stadtman and Barker, 1949). These reactions are of interest in view of recent growth studies (Holman, 1955), which support the early theory (McLeod and Gordon, 1923b) that growth inhibitory concentrations of peroxide are formed when catalase-negati...
The overall rate constants of the NO reaction with chloroalkylperoxy radicals derived from the Cl-initiated oxidation of several atmospherically abundant alkenes-ethene, propene, 1-butene, 2-butene, 2-methylpropene, 1,3-butadiene, and isoprene (2-methyl-1,3-butadiene)-were determined for the first time via the turbulent flow technique and pseudo-first-order kinetics conditions with high-pressur...
Beta band oscillations (13-30 Hz) are a hallmark of cortical and subcortical structures that are part of the motor system. In addition to local population activity, oscillations also provide a means for synchronization of activity between regions. Here we examined the role of beta band coherence between the internal globus pallidus (GPi) and (motor) cortex during a simple reaction time task per...
