Epoxy resins are often exposed to prolonged periods of sub-Tg temperatures which cause physical aging to occur. Because physical aging can compromise the performance of epoxies and their composites and because experimental techniques cannot provide all of the necessary physical insight that is needed to fully understand physical aging, efficient computational approaches to predict the effects o...

Introduction: Taking into account the growth of increase in the elderly population in Iran and the world, and the emergence of the phenomenon of feminization of aging, the present study has been conducted, with aim of examining the relationship between anxiety about aging and the perceived  and experienced gender inequality among the women of Shiraz city (Iran). Methods: This cross-sectional s...

Physical aging refers to structural relaxation of the glassy state toward the metastable equilibrium amorphous state, and it is accompanied by changes in almost all physical properties. These changes, which must be taken into account in the design, manufacture, and use of glassy polymer materials and devices, present a daunting challenge to theorists.

aging has negative effects on motor and cognitive functions, therefore finding appropriate strategies to prevent the decline of these functions is necessary. it seems that cardiovascular fitness obtained by aerobic activity is a physiological mediator that explains the relationship between physical activity and improved cognitive performance. the aim of this research was to assess the effects o...

Introduction: Health care providers play a central role as the main members of the health care service providers team for the elderly and their knowledge and attitudes towards the aging phenomenon can play an important role in the quality of health care services provision for the elderly. Therefore, the present study aims to comparatively investigate knowledge and attitude of health care provid...
