The paper proposes a study of the phenomenology driving the ageing mechanisms of electrochemical double layer supercapacitors (SCs) during their most common operating conditions. In particular, the paper focuses on the so-called life endurance (LE) and power cycling (PC) stresses. The paper first provides a description of the variables governing the SC behaviour at the microscopic scale (i.e., ...

Abstract: Cold working performed before an aging treatment has a significant effect on size and amount of precipitate produced. This could be caused by the increase in defect density, such as vacancies and dislocations. In this research, the Al-Cu-Si alloy was solution-treated, wear-tested and then artificially aged for a period of 1–5 h. Changes in the amount of precipitate, in the lattice par...

background physical activity is an important component of health in old age that provides personal independence, physical ability, and quality of life. objectives the current study aimed to evaluate physical activity and associated factors among the elderly population in kashan, iran. patients and methods this is a descriptive cross-sectional study. the sample was 400 elderly people (aged more ...

PURPOSE It was to test the validity and reliability of an online version of the Female Sexual Function Index (FSFI). METHODS An online version of the FSFI was compared to the pen and paper traditional version. Physiotherapy students in three cities were randomly allocated to two groups - G-pp/ol (n=126) and G-ol/pp (n=147). G-pp/ol women replied to th FSFI using the traditional pen and paper ...

Loss of brain function is one of the most negative and feared aspects of aging. Studies of invertebrates have taught us much about the physiology of aging and how this progression may be slowed. Yet, how aging affects complex brain functions, e.g., the ability to acquire new memory when previous experience is no longer valid, is an almost exclusive question of studies in humans and mammalian mo...

PURPOSE The purpose of this study was to investigate expectations regarding aging by middle-aged women in the community, and identify factors contributing to their expectations about aging. METHODS Participants in the survey for this study were 303 middle-aged women from community health centers and religious facilities in Seoul, Gyeonggi Province, and Chungcheongbuk Province. Data were colle...

Aging is the biggest risk factor for idiopathic Alzheimer's disease (AD). Recently, the National Institutes of Health released AD research recommendations that include: appreciating normal brain aging, expanding data-driven research, using open-access resources, and evaluating experimental reproducibility. Transcriptome data sets for aging and AD in humans and animal models are available in NIH...

This study investigated whether 184 volunteers from 20 to 79 years of age could perform eight timed balance tests and examined the relationship between test performance and age. All subjects were able to balance with their feet together and eyes closed for 30 seconds. The ability to balance on the right and left legs did not differ significantly. Subjects over 60 years of age were unable to bal...

The high integration level, complexity and performance achieved in new nanometer technologies make IC (Integrated Circuits) products very difficult to test. Moreover, long-term operation brings aging cumulative degradations, and new processes and materials lead to emerging defect phenomena. The consequence is obtaining products with increased variability in their behavior, more susceptible to d...
