Review of Mechanisms and Theories of Aging
Several factors have incentive role for study of aging which includes increasing of the average and maximum of human life span, the increase in percentage of elderly in the societies and proportion of the national expenditure utilized by them. The Recent views of aging indicating that aging is extremely a complex multifactorial process despite of earlier views about definite cause aging like ge...
متن کاملVascular Aging and Diseases: Molecular Mechanisms and Influences
Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...

A cheap and fast method of providing long term accommodating insoles is described. Room temperature vulcanizing (RTV) silicone rubber is used, with suitable coverings, to provide pain relief and support for feet and ankles. The combination of physical properties of the finished item provides a useful balance between support and flexibility which results in these insoles being readily accepted b...
متن کاملAccelerated Aging Effect on Epoxy-polysiloxane-Rice Husk Ash Polymeric Insulator Material
The performances of outdoor polymeric insulators are influenced by environmental conditions. The use of polymeric materials in a particular composition can be produced insulators that are resistant to environmental influences. This paper presents the effect of artificial tropical climate on the hydrophobicity, equivalent salt deposit density (ESDD), surface leakage current, flashover voltage, a...
