Research ArticleOpen accessIn the abstractEpoxy Insulators’ Lifetime Prediction Implementing Neural Network TechniqueL. S. Nasrat, A. M. IbrahimDue to wide implementation of Epoxy insulators in industrial applications and its economic implications; development of various Epoxy insulator materials has to be evaluated along with a reliable prediction methodology of their lifetimes. In this study, a new methodology based on Artificial-Neural-Networks (ANN) is developed to predict Epoxy insulators lifetime using laboratory measurements of their surface leakage current under accelerated … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 7 Aug 2012 · 7,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainability Education-A Challenge for South-East Asia and EuropeRenate Kärchner-Ober, Uwe DippelProblem statement: South-East Asia and Europe face rapid changes in social, economical and political terms. Though starting points are different, both regions experience similar problems. We see a strong slowdown of economic growth; changing proportions of the population through migration, natural disasters, economic reasons and aging populations. Problems and conflicts occur in the first decade of the new millennium, as … …Journal of Social Sciences, Vol. 7, Issue 1 · 18 Dec 2010 · 8,630 accessesView PDFCite

Research ArticleOpen accessIn the abstractIn vitro and In vivo Antioxidant Activity of Aphanamixis polystachya BarkAlluri V. Krishnaraju, Chirravuri V. Rao, Tayi V.N. Rao et al.Problem statement: Free radical stress leads to tissue injury and progression of disease conditions such as arthritis, hemorrhagic shock, atherosclerosis, diabetes, hepatic injury, aging and ischemia, reperfusion injury of many tissues, gastritis, tumor promotion, neurodegenerative diseases and carcinogenesis. Safer antioxidants suitable for long term use are needed to prevent or stop the progression of free radical mediated disorders. Approach: Many … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Mild Stresses Known to Increase Longevity in Drosophila melanogaster Flies do not Increase Resistance to Oxidative StressÉric Le BourgExposure to a mild stress at a young age (hypergravity, cold or heat) increases longevity and resistance to heat shocks in Drosophila melanogaster flies and it may also delay behavioral aging and increase resistance to other stresses. The effect of these mild stresses on resistance to oxidative stress has not been studied. Flies were thus fed on a saccharose solution … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,301 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mathematical Modeling Approach to Characterize Hormesis, Caloric Restriction and Toxicity in Mortality Data from Toxicity StudiesPatricia J. NeafseyThe mortality of a population reflects the combined effects of natural aging with environmental insults (e.g. toxicant exposure, caloric restriction, over feeding, infections, etc.). No single endpoint, such as carcinogenesis, completely describes toxicant-induced effects in laboratory animals. Mathematical models of mortality and time-dependent exposure to toxicants can yield indices of net injury from all causes. With careful manipulation of diet … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomedicine and Informatics Model of Alzheimer's DiseaseKang Cheng, Chang-Hua ZouIn a perspective of biomedicine and informatics, the mechanism of Alzheimer's, senile amnesia, or other aging-associated and cognitive impairment related diseases involve four important informative processing procedures: propagation, consolidation, retrieval and cognition, In this study, we systematically model the four procedures based on published experimental data. When modeling the propagation, we develop an equivalent circuit of biological membrane to describe … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 28 May 2007 · 6,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeuropsychological Dysfunction among HIV Infected Drug AbusersRamani S. Durvasula, Charles H. HinkinHuman immunodeficiency virus (HIV) has been documented to cause direct and indirect central nervous system dysfunction that can be observed as a progressive decline in neuropsychological functioning in a large proportion of persons with HIV and AIDS. Neuropsychological decline in individuals with HIV is characterized by cognitive and motor slowing, attentional deficits, executive dysfunction and memory impairment (characterized by intact … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,155 accessesView PDFCite
