introduction: physiological, anthropometrical and thermal perceptual are the most important factors affecting thermoregulation of men and women in workplaces. the purpose of this study was determining the validity of a questionnaire method for assessing women’s heat strain in workplaces. methods: this cross‑sectional study was carried out on 96 healthy women. data were continuously collected ov...

Abstract The dynamic necking of ductile metallic rods with large strain reverse loading history has received little attention in the published literature. A novel bespoke real time control setup is constructed to apply directly specimen gauge section up a maximum level ± 0.16. 304L stainless steel used as model material this study. subsequent tensile tests loaded specimens are performed from qu...

This article briefly reviews the history of coronavirus detection and states structural characteristics pathogenesis SARS-CoV-2 strain. Following conclusion that cellular senescence is thought to contribute susceptibility, this continues review structure function telomeres. Finally, it link between COVID-19 telomeres caused by

The probability of brain injury during an accident is dependent on the force history acting on brain tissue. The mostly used criterion for the injury probability assessment, the Head Injury Criterion (HIC), is based on the time integral of force (acceleration) history curve. HIC is used in the work for the assessment of helmet performance. Because of limited weight of the helmet, current design...

Batra [1] used a linear relationship between the second Piola-Kirchhoff stress tensor S and the Green-St. Venant strain tensor E to study finite simple shearing and finite simple extension deformations of an elastic body. In each case he found that the tangent modulus (i.e. the slope of the shear stress vs. the shear strain curve or the slope of the axial stress vs. the axial stretch curve) is ...

BACKGROUND Magnetic resonance (MR) imaging has established its usefulness in diagnosing hamstring muscle strain and identifying features correlating with the duration of rehabilitation in athletes; however, data are currently lacking that may predict which imaging parameters may be predictive of a repeat strain. PURPOSE This study was conducted to identify whether any MR imaging-identifiable ...
