Background and Aim: The recently emerged symptoms of population aging have raised serious concerns in some developed countries. A recent report by the United Nations (UN) indicates that aging is more rapidly growing and is even more serious in developing countries than it is in certain other countries. Therefore, this study is aimed to determine the impression of aging on non-oil economic g...
conclusions regular aerobic exercise could increase plasma klotho levels, and this could be an explanation for exercise-related anti-aging effects. background klotho is an anti-aging protein that is predominantly secreted by the kidneys. objectives the aim of the study was to measure and compare the circulating klotho levels in the serum of trained athletes and in healthy, non-athlete controls....
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Objective: To explore perceptions of aging among Korean undergraduate nursing students. Methods: The participants for the study were 102 undergraduate nursing students, selected from two universities in Korea. The questions were non-structured, open-ended in order for the students to make sufficiently complete statements regarding their experiences with aging. Results: The collected materials w...
The thermogravimetric analysis (TGA) and the differential thermal analysis (DTA) were applied to investigations of aging processes in some electroinsulating polymeric materials (glass reinforced epoxy resin, NBR ( two sorts), styrenated unsatured polyester resin, hydrogenated NBR (T80), polychloroprene rubber , EPR) and to the measurement of aging reaction rates. It is shown that thermal analys...
Background and Objective: Aging like many complex traits is the result of interaction between genome and environmental factors and epigenetic mechanisms as a central connector links these two markers. So far, investigations on age-related characteristics and biomarkers predicting survival and risk of death have been carried out, none of which led to an overall consensus among the researchers. I...
Background and Aim: Although the physical properties of modern glass ionomers have been extensively reported, few studies have examined how these parameters change with age. This experimental study aimed to investigate the effect of aging on the compressive strength of resin-reinforced glass ionomers. Material and Methods: Two glass ionomers (Fuji IX GP Fast, GC, Japan, and Ketac Universal, 3M,...
deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...
Aging phenomena often play a key role in realistic rendering: excepting when the desired result is specifically a brand-new virtual object, their absence can lead to non-realistic surfaces, looking too clean and smooth. To solve these problems, artists either compose multiple textures manually, or directly modify object geometries. However, such techniques may not be suitable to obtain realisti...
