Research ArticleOpen accessIn the abstractSurface Properties of Cell-treated Polyethylene TerephthalateBing Shi, Hong Liang, Thomas B. Kuhn, Lawrence K. DuffyThe materials used in artificial joints undergo degradation through fatigue and corrosive wear in human body. The lifetime for well-designed artificial joints like hip joints is at most 12 years and a patient will usually have two total joint replacements during his/her lifetime. Tissue engineering, an alternative to total joint implantation, is the replacement of damaged tissue with the tissue … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Wear Map for the Sliding and Rotational Wear behavior of ShaftsAl-mahasne Mayas MohammadThis study was an attempt to study the wear calculation method for rotating shaft in the friction couple type shaft-cuff in conditions of oiling in high dusty environment. The size and quantity of abrasive particles that go into the clearance between friction surfaces, definition of the pressure including the load in conjugate that is given by the cuff spring as … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractCPI-1189 Protects Against Dextran Sulfate Sodium-induced Colitis in MiceBeverley Greenwood-Van Meerveld, Karl R. TylerNitrone-related therapeutics (NRTs) represent a new class of small molecules potentially effective in the treatment of inflammatory bowel disease (IBD) by protecting cells from damage caused by excess inflammation and/or oxidative stress. The goal of this study was to determine the efficacy and potency of CPI-1189, a novel therapeutic agent, in dextran sulfate sodium (DSS)-induced colitis in mice. Mice received … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 3 · 30 Sep 2006 · 6,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrocontroller Based Power SupplyTanvir Singh Mundra, Er. Satwinder Singh Sachdeva, K.S. KahlonThese days, majority of electronic devices work on DC power source, so there was a requirement of a reliable and customized power supply. Generally, the requirements are not too varied, but still they require every time a new hardware designing. The idea presented here is to build a microcontroller controlled power supply[1] that is flexible enough to meet different customer … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Modern Appraisal of Ancient Etruscan Herbal PracticesA. P. Harrison, E. M. BartelsIndividuals in antiquity would have been exposed to both cheese and red wine and perhaps as many as 10-40% of the population would have suffered at some time in their life from a migraine headache. Furthermore, individuals in antiquity would also have been exposed to their fair share of childhood stress and therefore would have been predisposed to arthritis in … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 2 · 30 Jun 2006 · 7,481 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 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Changing Pathology of NeuroAIDS Associated with Drug Abuse in the Era of HAARTE Bell Jeanne, C. Anthony Iain, Simmonds PeterCompliance with highly active antiretroviral therapy (HAART) arrests HIV induced immune collapse and reduces the prevalence of severe central nervous system (CNS) complications, including HIV associated dementia and encephalitis. However minor cognitive disorders remain common and recent autopsy studies have demonstrated the presence of subtle neuropathological abnormalities in HAART treated individuals, including persistent neuroinflammation and enhanced deposition in the brain … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,446 accessesView PDFCite
