the glass transition temperature (tg) and the melting temperature (tm) of gelatin at water contents between 7 and 14% were measured using differential scanning calorimetry. the plasticisation of the polymer by water led to a decrease in tg and tm. the tg of partially crystalline gelatin was higher than that of the amorphous one obtained by quenching from the melt. the enthalpy relaxation occur...
increasing of the aging population in most of the developed countries should be more attention to the health issues of this aged group. in iran, the ageing program has been launched and some institutes or organizations have been in charge of this program. the coordination of health policies and activities in elderly care programs and ageing networks could be helped to improve of elderly life sp...
in the present work, the influence of aging temperature on mechanical properties and sound velocity of maraging steel m350 was investigated. for this purpose, first, samples were solution annealed at 825◦c for 2 hours and then age hardened at 510◦c-600◦c for 3 hours. hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
background: increased life expectancy and the growing phenomenon of aging can lead to increased burden of chronic diseases (cds) which adversely affects the overall health of elderly, their sexuality in particular. sexual life of aged population is overlooked in many of the societies. in the present narrative review, we aim to assess the impact of cds on sexual function of elderly people. mater...
introduction: motor skills play an important role during life span, and older adults need to learn or relearn these skills. the purpose of this study was to investigate how aging affects induction of improved movement performance by motor training. methods: serial reaction time test (srtt) was used to assess movement performance during 8 blocks of motor training. participants were tested in two...

This paper reviews the potential role of honey as a therapeutic antioxidant to reduce oxidative stress and improve cognitive ageing. All articles indexed to PubMed Central (PMC) were searched using the following key words: honey, antioxidant, memory and ageing. Honey is a natural insect-derived product with therapeutic, medicinal and nutritional values. Antioxidant properties of honey quench bi...
The 17-4PH alloy is a martensitic stainless steel with 3–5 wt% Cu, strengthened by the precipitation hardening. Due to excellent mechanical properties, corrosion resistance and ease of heat treatment, this alloy has unique applications in nuclear power plants and marine constructions. In this paper, the influence of ageing heat treatment, solution annealing followed by ageing at 480, 550 and 62...
The living of the elderly has been turned into a problematic issue affected by social, cultural and economic changes, however, this problematic is not registered in policy makings and there is not appropriate social polices associated to the elderly. The subject of the current study is observe social policies in the context of development plans after the Revolution, to discover overt and covert...
