Polypropylene (PP) has a wide range of applications in the automobile bumpers due to its many excellent properties. Mechanical properties PP for are investigated through an artificial accelerated aging test. The rules after different years normal use and test analyzed. correlation between natural artificially is also explored. It provides reference study polymers automotive applications. Result...
Three kinds of fiber reinforced plastic (FRP) composites, including modified polyurethane resin (LGD), epoxy resin (E44) and modified unsaturated polyester resin (D33) glass-fiber reinforced plastics, were subjected to a 5000 h multi-factor accelerated aging test according to the power industry standard. To examine aging resistance and thermal stability of transmission towers made by these thre...
The aquatic ecotoxicity testing of nanoparticles is complicated by unstable exposure conditions resulting from various transformation processes of nanoparticles in aqueous suspensions. In this study, we investigated the influence of exposure timing on the algal test response to silver nanoparticles (AgNPs), by reducing the incubation time and by aging the AgNPs in algal medium prior to testing....
Background: Many of the old age problems result from unhealthy lifestyles in this stage of life. Focusing on successful aging and adopting Health-Promoting Behaviors (HPB) can prevent and decrease aging problems which in turn decreases the financial burden and related costs. Methods: This clinical trial study was conducted on 464 elderly people over 60 years who were admitted at Heal...
While successful aging is often defined as the absence of disease and disability or as life satisfaction, self-transcendence may also play an important role. The objective of this research was to test a nursing theory of successful aging proposing that transcendence and adaptation predict successful aging. In this cross-sectional exploratory study, a convenience sample of older adults (N = 152)...
