Background: India, the second most populous country is facing demographic transition. cognitive decline one of normative changes aging; however, this may impact both physical and mental health an individual. Quality life measures successful aging. This study was conducted to correlate level cognition quality in elderly population. Our aim assess geriatric population using OPQOL-35 assessment by...
In this article, we conduct research on the effect of corrosion tests hydrogen diffusion process in gas steel electrochemical permeability tests. This show that a long test time reduces coefficient by an order magnitude, indicating formation aging defects steel. During operation, decreases two orders which also indicates large number Consequently, based change material, it is possible to assess...
An accurate and real-time knowledge of temperatures in insulated-gate bipolar transistor modules is crucial for reliability analysis thermal management power electronic converters. For this purpose, paper establishes an integrated equivalent circuit model comprising self-heating impedances cross-heating to provide a temperature profile the junction solder joints during various operations case a...
skin aging is a continuous process that exhibits fine and deep wrinkles, thin and transparent skin, loss of underlying fat, dry skin and itch, following decreased collagen and elastin synthesis. both extrinsic and intrinsic agents are considered in the pathogenesis on skin aging. extrinsic factors such as sun exposure, windy and dry weather, nutrition, and lifestyle may induce premature aging,...
The temperature in the southwest Castel highland area is relatively low, and asphalt concrete on road surface a low-temperature state all year round. Strong ultraviolet radiation will interfere with material cause it to fracture damage. This paper uses bending test thermal stress constrained specimen (TSRST) performance of mixtures different gradation types under (UV) aging conditions. Existing...
female fertility begins to decline many years prior to the onset of menopause despite continued regular ovulatory cycles. age related infertility is due to oocyte abnormalities and decreased ovarian reserve. treatment of infertility when the cause is limited to decreased ovarian reserve is empirical at present except for oocyte donation. this mini review of the literature covers all available e...
background aging is an irreversible natural process characterized by a decline in both the physical and mental status of individuals. because of multiple factors, this process and its consequences vary greatly between individuals. a successful aging (sa) is the target of current health policies and well-being of individuals. knowing the factors that contribute to sa and its barriers would trans...
collection of multiple processes that increase the chronological age of an organism leading to death is defined as aging, and even though important, it is poorly understood. recent research has shown that aging is due to biochemical and genetic changes, in interaction with environmental effects, including diet and nutrition. most knowledge on aging is based on genetic model system, but its mol...
background: lower limbs antigravity muscles weakness and decreased functional ability have significant role in falling. the aim of this study was to find the effects of aging on muscle strength and functional ability, determining the range of decreasing strength and functional ability and relationship between them in healthy women. methods: across-section study was performed on 101 healthy wome...
background chronological aging is associated with a decrease in physical activity levels and consequently a decline in physical fitness, which may contribute to adverse conditions such as cardiovascular disease, hypertension, obesity and physical impairment. objectives this study sought to examine the effects of an 8-week physical activity intervention program on nutritional status and health-r...
