Marvelous bending/straightening effects of two-way shape memory alloy (TWSMA) help their employment in design and manufacturing of new medical appliances. Constrained ageing with bending load scheme can induce two-way shape memory effect (TWSME). Scanning electron microscope (SEM) analysis, electrical resistivity measurement (ERM) and differential scanning calorimetry (DSC) are employed to dete...

U-7.5Nb-2.5Zr cladded in Zircaloy-4 is one of the most studied fuel prototypes. The Nb and Zr are added to U stabilize body-centered cubic (BCC) gamma phase grant mechanical swelling resistance. undergoes α′′ transformation, generating compressive stresses due volume reduction. also can transform a combination α + γ2 (equilibrium phases), which known be hard brittle. This work had objective tes...

apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. in...

introduction: women are facing inequalities including health, thus their health deserves attention. investigating people’s health status from their viewpoints is an important measure in terms of public health of society and an indicator to determine the efficiency of health system.  this study aimed at evaluating the self-assessed health of older women living in shiraz and yasuj. methods: this ...

introduction: ageing brings different experiences for individuals. any individual learn about ageing from childhood whatever formal or informal. no matter they learn, what and how they learn is important. this study aimed to assess impact of an educational program on ageism in those people lower 20 years of age. methods: this interventional study was conducted among school and university studen...

Most industrialised societies face rapid population ageing over the next two decades, including sharp increases in the number of people aged 85 years and over. As a result, the supply of and demand for aged care services has assumed increasing policy prominence. The likely spatial distribution of the need for aged care services is critical for planners and policy makers. This article describes ...

Leaf longevity (LL) varies more than 20-fold in tropical evergreen forests, but it remains unclear how to capture these variations using predictive models. Current theories of LL that are based on carbon optimisation principles are challenging to quantitatively assess because of uncertainty across species in the 'ageing rate:' the rate at which leaf photosynthetic capacity declines with age. He...

This research was carried out to study the effect of ageing on antioxidant and biochemical changes of wheat (Triticum aestivum L.) seeds. The experiment laid out in completely randomized design (CRD) with four replications in Islamic Azad University, Boroujerd Branch, Boroujerd, Iran in 2015. The seeds of wheat (cv Sardari) were harvested at maturity and ageing treatments were done at 43° C wit...

The paper aims to examine the population ageing as a new phenomenon effecting rural areas in Iran. Population ageing is going up throughout the country especially in the rural areas by 6.8 percent. fertility decline, increase in the youth migration to cities, and coming back to rural areas after retiring are the major factors which involve in rural ageing. This may jeopardize the communities. f...
