Research ArticleOpen accessIn the abstractFolding of Trefoil Knot and its GraphM. El-Ghoul, A. I. Elrokh, M. M.A. ShamiriIn this study, we introduce the effect of the folding, conditional folding, retraction and conditional retraction on trefoil knot and its graph. We introduce the sheeted trefoil knot and the folding and retraction of this type and present the limit of foldings. We study how to obtain the types of link graph by adjacency matrix for any number of vertices … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Optimal Software Rejuvenation Schedule via Semi-Markov Decision ProcessHiroyuki Eto, Tadashi DohiSoftware rejuvenation is a preventive and proactive maintenance policy that is particularly useful for counteracting the phenomenon of software aging. In this study we consider an operational software system with multiple degradations and derive the optimal software rejuvenation policy minimizing the expected operation cost per unit time in the steady state, via the dynamic programming approach. Especially, we show analytically … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecreational Viagra Use and Sexual Risk among Drug Abusing MenDennis G. Fisher, Robert Malow, Rhonda Rosenberg et al.Until recently, the Viagra connection to HIV was anchored in older adults. However, CDC investigation showed stability in 50+ HIV diagnoses on the heels of upward trends in risk indicators among men who have sex with men (MSM) and substance abusing populations. Signs have increasingly pointed to recreational drug use among younger populations, to which Viagra is being added to … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 10,610 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterventions and Patterns of Risk in Adolescent HIV/AIDS PreventionRobert M. Malow, Rhonda Rosenberg, Geri Donenberg, Jessy G. DévieuxMid-way through the third decade of experience in preventing HIV/AIDS among adolescents, behavioral interventions and outcomes for high risk subgroups have generated evidence extremely instructive for navigating future priorities in reducing transmission risk behavior. Youth who abuse alcohol or drugs, who are detained or incarcerated, or have mental health co-morbidity such as externalizing disorders, represent the most significant challenge to … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractAction of Calciotropic Hormones on Bone Metabolism-Role of Vitamin D3 in Bone Remodeling EventsCatharine Andresen, Ellen Olson, Chudy I. Nduaka et al.Vitamin D3 is known to have immunosuppressive effects that can be beneficial for treatment of immune disorders and transplant rejection, however therapeutic application is limited due to hypercalcemia and hypercalcuria. The goal of our studies was to explore both the acute and steady state effects of vitamin D3 on bone remodeling as potential limiting factors to broader use of vitamin … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 8,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioceramics for Tissue Engineering Applications-A ReviewSunho Oh, Namsik Oh, Mark Appleford, Joo L. OngThree dimensional (3-D) scaffolds have been explored in an attempt to persuade the body to heal or repair tissues that do not do so spontaneously. Considerable advances in tissue engineering and regeneration have been accomplished over the last decade. However, the material and 3-D scaffolds ideal for optimal regeneration of missing or lost tissues has not been identified. While current … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 10,423 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Transcutaneous Electrical Stimulation on the Healing of Radial Fracture in RabbitD. Sharifi, P. Yunessi, F. Sasani, S. MohitmafiThe study was performed on 10 New Zealand white rabbits 6 months old and weighing 3.0 to 4. 5 kg so as to evaluate the effects of Transcutaneous Electrical Stimulation (TES) on the right radial fracture healing. A piece of 0. 5 cm full thickness of right midshaft of radial bone was removed in all rabbits under general anesthesia. They … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 6,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating Soil Contamination with Kriging Interpolation MethodFatima Zohra Benmostefa LarguecheThe main objective of this study was to investigate whether Kriging is a useful tool to estimate the spatial distribution of ground pollutants in contaminated land. The second objective of this work was a more practical one. It consists on the identification of areas that should be subjected to remedial actions and also on deciding which contaminant needs to be … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 8,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Software Quality Model for Evaluating COTS ComponentsAdnan Rawashdeh, Bassem MatalkahStudies show that COTS-based (Commercial off the shelf) systems that are being built recently are exceeding 40% of the total developed software systems. Therefore, a model that ensures quality characteristics of such systems becomes a necessity. Among the most critical processes in COTS-based systems are the evaluation and selection of the COTS components. There are several existing quality models used … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 11,425 accessesView PDFCite
