heat stress particularly  at  outdoor  workplaces in hot-dry    climates can  disrupt    the physical or mental functions and effect negatively on human performance. we aimed to study the effect of heat stress on productivity loss among workers of brick workshops in qom province – central iran. this cross-sectional descriptive and analytic study was performed on 184 workers in 40 brick workshop...

The difference in the potential energy in an elastic three-dimensional domain with a V-notch with and without a small crack ( δΠ ) under a general mixed mode I+II+III loading is provided as an asymptotic series. It involves the V-notch edge stress intensity functions, the area of the formed crack, and special geometrical functions that can be pre-computed and tabulated. Importantly, the stress ...

A comprehensive understanding of the cellular functions of the Hsp90 molecular chaperone has remained elusive. Although Hsp90 is essential, highly abundant under normal conditions, and further induced by environmental stress, only a limited number of Hsp90 "clients" have been identified. To define Hsp90 function, a panel of genome-wide chemical-genetic screens in Saccharomyces cerevisiae were c...

It is widely accepted that chronic stress, which is considered a risk factor for several neuropsychiatric disorders, may have detrimental effects on prefrontal functions. In animal models, chronic stress produces morphological, physiological and functional alternations in the rat medial prefrontal cortex (mPFC). Specifically, repeated restraint stress results in mPFC dendritic atrophy that is a...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...

We compute the disk potential of Gelfand–Zeitlin monotone torus fiber in a quadric hypersurface by exploiting toric degenerations, Lie theoretical mirror symmetry, and structural result Fukaya category.
