Objectives In recent decades, it has become important to approach aging issues from the point of view that can ensure older adults’ Quality of Life (QoL). As a result, countries have adopted a positive perspective with regard to aging, including active aging. The fact is that indigenous understanding of active aging is an unavoidable necessity for every society. Thus, the current study&rs...
Objectives: The beliefs and perceptions regarding aging have an important effect on the well-being of the elderly population. A self-regulation model is one of the useful theoretical models to explain the role of perceptions and beliefs about aging in determining the health outcomes of elderly people. The aim of this study was to determine the relationship between aging-related perception ...
The present study was undertaken to investigate the effect of pre-aging and aging parameters (time and temperature) on the mechanical properties of Al-Mg-Zn (7075) alloys. Ultimate tensile strength, 0.5% offset yield strength and % elongation measurements were carried out on specimens prepared from cast and heat treated 7075 alloys. Aging treatments were carried out for the as solution treated ...

The aging behavior is investigated for thin films of atactic polystyrene through measurements of complex electric capacitance. During isothermal aging process the real part of the electric capacitance increases with aging time, while the imaginary part decreases with aging time. This result suggests that the aging time dependence of the real and imaginary parts are mainly associated with change...
background: aging population and prevalence of diseases like cancer among them have affected general health of the elderly, so that one of the influential factors on health components of elderly patients with cancer is death anxiety, which has important consequences in them. methods: in this cross-sectional (descriptive correlational) study, 130 elderly patients with cancer undergoing chemother...
We present an effective time approach to predict long and short time rheological behavior of soft glassy materials from experiments carried out over practical time scales. Effective time approach takes advantage of relaxation time dependence on aging time that allows time-aging time superposition even when aging occurs over the experimental time scales. Interestingly, experiments on a variety o...
