results the results showed that the average hr at resting, sitting (32℃ ± 0.1℃), and light workload (30℃ ± 0.1℃) were 78.52 ± 12.10, 69.74 ± 11.98, and 110.78 ± 17.91 beat/min, respectively. the average of ear canal temperature was estimated at 36.70℃ ± 0.36℃ for sitting workload and at 36.71℃ ± 0.27℃ light workload. conclusions the findings of this study illustrated that the average hr and the...

conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...

Perceptual closure is one of the principles by which the visual system groups disjointed contour segments belonging to a single object. Recently it has been reported that grouping based on perceptual closure operates only upon contour elements of a consistent contrast sign and is eliminated when closed contours contain contrast reversing segments [Elder, J. & Zucker, S. (1994) A measure of clos...

Salmonella enterica serovar Infantis is one of the prevalent Salmonella serovars worldwide. Different emergent clones of S. Infantis were shown to acquire the pESI virulence-resistance megaplasmid affecting its ecology and pathogenicity. Here, we studied two previously uncharacterized pESI-encoded chaperone-usher fimbriae, named Ipf and Klf. While Ipf homologs are rare and were found only in S....

The present study was designed to assess the effects of the Transcendental Meditation (TM) program on strength of the nervous system, perceptual reactance, reaction time, and auditory threshold. Three reaction time indices of strength of the nervous system were utilized: 1) Nebylitsyn's index, 2) the slope index, and 3) the low level stimulation index. Absolute auditory threshold was the fourth...

Perceptual learning, improvement in perceptual skill with practice, can improve both accuracy and consistency of perceptual reports. Regression statistics can quantify ongoing calibration of perceptible scalar properties (i.e., improvements in accuracy and consistency) because, ideally, actual and perceived values are linearly related. Changes in variance accounted for (r2) track changes in con...
