Research ArticleOpen accessIn the abstractThe Use of Taguchi Method to Determine Factors Affecting the Performance of Destination Sequence Distance Vector Routing Protocol in Mobile Ad Hoc NetworksHazura. Mohamed, Muhammad Hisyam Lee, Mazalan Sarahintu et al.In this study, Taguchi method was used to identify the several factors that may affect the performance of Destination Sequence Distance Vector (DSDV) routing protocol. The performance of DSDV routing protocol in mobile ad hoc networks were greatly influence by factors such as node speed, node pause time and traffic load. Problem statement: By using orthogonal experimental design and analysis … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Integration of Network-Based Models for Spill Response and Homeland SecurityDavid E. Amstutz, Rakesh Bahadur, Jonathan M. Pickus et al.The integration of three hydraulic GIS (Geographic Information System) applications is presented which represent the water infrastructures of cities and urban areas and US streams and rivers. The water infrastructures include drinking water distribution systems, wastewater collection systems and source water. The National Research Council[1] states that problems dealing with the collective behavior of networks such as river systems, water … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesizing Behavioral Model of Event-Based RequirementsSeyyed M. BabamirProblem Statement: in the software engineering field, satisfaction of user's requirements by software has been a matter of concern. Therefore, monitoring software behavior against user's high-level requirements has already received a considerable and significant attention. However, the gap between low-level software behavior and high-level requirements has put an obstacle in the way of monitoring. Approach: to overcome the obstacle, we … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrochemical Differentiation of Salinisation Process of the Water in Endoreic Semi-Arid Basin: Case of Rémila Basin, AlgeriaHouha Belgacem, Kherici Nacer, Kachi Slimane, Valles VincentThe aim of this study is to determine and treat a hierarchical basis of the various mechanisms responsible for the space variation of the water quality in a endoreic semi-arid basin. The water chemistry showed a large variability in space and time. The total dissolved solid (TDS) in water increases from upstream to downstream due to the effect of the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetinoids and Opioids: Factors in the Development of HIV-Related Neurological DiseaseWalter Royal, III, Joseph L. BryantNeurological disease occurs frequently in HIV-infected individuals and may occur at even higher rates among infected drug users. Among the potential mechanisms that promote such impairment, retinoid deficiency may have selective effects that could both lead to alterations in immune function and enhanced replication of HIV. Studies are currently underway to examine the possible selective effects of retinoid receptor activation … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 6,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Frequency of Polymorphisms affecting Lead and Mercury Toxicity among Children with AutismShannon Rose, Stepan Melnyk, Alena Savenka et al.Individual risk of developmental neurotoxicity with exposure to environmentally relevant levels of lead and mercury is likely to be determined by genetic susceptibility factors as well as additive interactions with other environmental pollutants, cumulative dose, and the developmental stage of exposure. The apparent increase in autism diagnosis over the last 15 years has enhanced interest in the possibility that an … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic and Non-Hormetic Dose-Response Functions in Stress Effects on Memory and Synaptic Plasticity: Issues and MechanismsPhillip R. Zoladz, David M. DiamondOver a century of behavioral research has shown that stress can exert both positive and negative effects on memory. We have explored the idea that the complex effects of stress on learning and memory can be characterized by hormetic- and non-hormetic dose-response functions, in which stress may either stimulate or impair brain memory mechanisms, depending, in part, on the timing … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractElucidating the Mechanism(s) of Hormesis at the Cellular Level: The Universal Cell ResponsePaul S. AgutterMany environmental stressors elicit biphasic effects from single cells. Such cellular hormesis may be interpreted in terms of (a) the superimposition of simple biochemical processes or (b) the non-specific behaviour of the cell. The latter approach is emphasized in this article and identified with the universal cell response (UCR); however, the importance of identifying molecular-level concomitants of the UCR is … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 13,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractMedical Consequences of Drug Abuse and Co-occurring Infections: A Brief ReviewJag H. KhalsaToday substance abuse remains one of the major problems in the world with millions of people abusing legal and illegal drugs. In addition, almost one-third of the world population of 6.7 billion people may also be infected with one or more infections. Both drugs of abuse and infections are associated with enormous burden of social, economic and health consequences.
