the aim of this investigation was to compare the level and the pattern of attention demands of a volleyball jumping serve using a probe reaction time (rt) technique. 14 junior elite volleyball players performed 60 jumping serves (js) with their preferred hand. jumping serve was performance as the primary task and verbal rt that was administered in four probe positions (pp) as secondary task. re...

introduction ventilator-associated pneumonia (vap)  is one of the most serious and  prevalence of  complication  among patients in the intensive care unit nosocomial infections, which are often recognized after detecting symptoms. to date, there has been no proper clinical and diagnostic marker for early detection of this disease. in this study, two hcn4 and adam8 genes in patients with vap wer...

background: leishmaniasis is a parasitic disease caused by different species of leishmania parasites with a wide range of clinical manifestations . antimonial compounds such as meglumine antimoniate (glucantime) are the first line drugs for the treatment of leishmaniasis. however, according to reports of the drug resistance of parasites, the efficacy of antimonial compounds is low. the atp-bind...

OBJECTIVES To evaluate the effect of concussion on clinically measured reaction time (RT(clin)) and in comparison to a computerized reaction time measure (RT(comp)). DESIGN Prospective, repeated measures observational study. SETTING Athletic training clinic at a National Collegiate Athletic Association (NCAA) Division I university. PARTICIPANTS Data are reported for 9 collegiate athletes ...

This study examines the impact of a resistance-band functional exercise program, compared with a recreational exercise program, on physical fitness and reaction times in persons older than 60 years. Fifty-four community-dwelling volunteers (71.76 ± 6.02 years) were assigned to a specific exercise program: Functional activity program (focused on resistance-band multi-joint activities; experiment...

PURPOSE To compare reaction time (RT) to rod incremental and decremental stimuli expressed in physical contrast units or psychophysical threshold units. METHODS Rod contrast detection thresholds and suprathreshold RTs were measured for Rapid-On and Rapid-Off ramp stimuli. RESULTS Threshold sensitivity to Rapid-Off stimuli was higher than to Rapid-On stimuli. Suprathreshold RTs specified in ...

Evidence suggests that Reaction time (RT) is affected by human behaviour in that stimuli are processed and conducted faster and more accurately when they are presented directly to the specialised hemisphere and responded to more quickly when stimulus and response are mediated by the same hemisphere. The purpose of the current study was to investigate the effect of laterality using one parameter...

The paper was conducted to assess the importance and challenges encountered in the current machine evaluation system in an electronics company as perceived by the respondents. In addition, it also sought to understand the acceptability of the new developed Real-Time Auto-locked Software for Electronics Company (RT-ASEC). The new automated machine evaluation software can detect any irregular mac...
