Since medical practice is one of the stressful occupations as a result of high work-load, sleepless conditions and hyposomnia, management of severely ill patients and occasionally death of them, this study was performed to determine the rate of stress in a group of specialists and residents of different fields in Shaheed Beheshti University of Medical Sciences. The descriptive and cross-sectio...

Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...

Electromagnetic fields (EMF), in both ELF (extremely low frequency) and radio frequency (RF) ranges, activate the cellular stress response, a protective mechanism that induces the expression of stress response genes, e.g., HSP70, and increased levels of stress proteins, e.g., hsp70. The 20 different stress protein families are evolutionarily conserved and act as 'chaperones' in the cell when th...
