background: exercise and consumption of green tea affect the aging process. however, the effect of exercise training combined with green tea extract on leukocyte telomere length, quality of life (qol) and body composition in aging has so far been unclear and inconsistent. objective: the aim of the present study was to determine the effectiveness of aerobic training intervention and green tea ex...

objective: recently, a wide variation has been reported in delivery of the target torque by spring-style mechanical torque limiting devices (mtlds) but the effect of aging on their accuracy has not been independently evaluated. the purpose of this study was to determine the effect of aging on the accuracy of spring-style mtlds. methods: in this in-vitro experimental study, 15 new spring-style m...

The aim of this study is to investigate effects of isothermal aging on mechanical properties of fiber metal laminates (FMLs) and glass/epoxy composites. For this purpose, both materials were fabricated using the wet lay-up manufacturing technique under vacuum pressure. Both the glass/epoxy composites and the FML specimens were then subjected to isothermal aging (130°C, dried air) for up to 5 we...

modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. this paper present the effect of there novel modifier as precipitated calcium carbonate (pcc) and two type of nanoclay on rheological properties of bitumen binder. various blends of modifier and bitumen were selected and...

Reliability, a crucial requirement in any modern microprocessor, assures correct execution over its lifetime. As mission critical components are becoming common commodity systems, e.g., control of autonomous cars, the demand for reliable processing continues to grow. The latest process technologies have aggravated situation by causing microprocessors be highly vulnerable reliability concerns. T...

This study was conducted to evaluate the effect of Purslane hydro alcoholic extract on blood urea nitrogen (BUN), creatinine (Cr) and kidney histopathology of kidney aging model induced by D-galactose in female mice. In this experimental study, 72 female Naval Medical Research Institute (NMRI) mice (30-35 g) were randomly divided into six groups including: control, Purslane, D-galactose, D-gala...
