Research ArticleOpen accessIn the abstractDihydrobiopterin (BH2): Key Determinant in Influencing Arginine Mediated Endothelial Tolerance and DysfunctionSrinidi Mohan, Harsh Patel, Jorge Bolinaga et al.The redox-sensitive tetrahydrobiopterin (BH4) is an essential cofactor that is required by endothelial Nitric Oxide Synthase (eNOS) for L-arginine (ARG) mediated Nitric Oxide (NO) generation. Oxidation of BH4 causes cofactor insufficiency and uncoupling of eNOS, resulting in product switching from NO to O2⋅– production. Here we tested the hypothesis that eNOS uncoupling is not simply a consequence of BH4 insufficiency, … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Diversity of Some Saudi Barley (Hordeum Vulgare L.) Landraces Based on Two Types of Molecular MarkersMohamed Abdel Hamid Mohamed El-Awady, Adel Ahmed El-Sayed El-Tarras, Salah El-Din El-AssalProblem statement: Very little is known about the genetic diversity and morphological variability present in barley landrace in KSA, a country experiencing loss of biodiversity because of replacement of landraces with modern landraces. Approach: The molecular markers RAPD and ISSR were used as an efficient tools to estimate the intra-and inter-cultivar polymorphism among six barley KSA landraces collected from different … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Concept of Event-Driven TimeSergey K. AityanThe most fascinating feature of time is that there is no time at all. This study introduces the concept of event-driven time. Time is considered a count of changes or events that set up a local “clock” in each system. With such an approach, every system runs its own local time. Time does not exist without changes in the system. … …Physics International, Vol. 2, Issue 2 · 26 Jan 2012 · 8,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractEntropyomics as the Blueprint of the Logic of Normal Cell Division and MalignancyKambiz AfrasiabiProblem statement: In this article I propose a blueprint based on one of the most fundamental laws governing the known universe, namely the second law of thermodynamics and I present support for its central role in initiation of mitosis and relationship of the other sub cellular compartments and their organization. Approach: Life is considered to be the most sophisticated antientropy … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 10,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractSessile Drop Evaporation and Leidenfrost PhenomenonA. K. Mozumder, M. R. Ullah, A. Hossain, M. A. IslamProblem statement: Quenching and cooling are important process in manufacturing industry for controlling the mechanical properties of materials, where evaporation is a vital mode of heat transfer. Approach: This study experimentally investigated the evaporation of sessile drop for four different heated surfaces of Aluminum, Brass, Copper and Mild steel with a combination of four different liquids as Methanol, Ethanol, Water … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Bidding Strategies for a Small Generation Company in a Day-Ahead Electricity Market with Bilateral Contracts Taken into AccountAzmi Saleh, Takao Tsuji, Tsutomu OyamaProblem Statement: Deregulation power systems have been force to change their structures, from vertically integrated to open market systems. Each generation company (Genco) is required to compete with rivals through bidding in a pool market and making a bilateral contract with a distribution company (Disco) or consumers to maximize its own profits. A unit commitment becomes responsible for each Genco … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractDNA Code Word Design for DNA Computing with Real-Time Polymerase Chain ReactionMuhammad Faiz Mohamed Saaid, Zuwairie Ibrahim, Mohamad Shukri Zainal Abidin et al.Problem statement: A number of DNA computing models to solve mathematical graph problem such as the Hamiltonian Path Problem (HPP), Traveling Salesman Problem (TSP), and the Shortest Path Problem (SPP), have been proposed and demonstrated. Normally, the DNA sequences used for the computation should be critically designed in order to reduce error that could occur during a computation. We have … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation Into The Behavior of Circular Pad Shallow Foundations Supported By Geogrid Reinforced SandS. M. Marandi, M. H. Bagheripour, R. Rahgozar, A. R. GhirianThis study seeks to widen the pool of knowledge on the use and characteristics of geosynthetics, specifically in the area of circular foundations supported by geosynthetic reinforced sand. The main objective of the work was to increase the awareness of circular foundation systems and thus increase the accuracy of current laboratory methods. Also, compare the results with that of previous … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Psychology Undergraduate Curriculum in Developing Countries: A Personal Note with Illustrations from BrazilCharles I. Abramson, Amauri B. BartoszeckIn this article we suggest various ways in which the undergraduate curriculum for psychology students can be improved in developing countries. Suggestions based on the author's experience in the northeast of Brazil include forming psychology clubs, creating community outreach programs, establishing a human subject pool, skills training, developing research-based courses and seeking outside funding. …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,328 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Recipe Based Service Composition in Ubiquitous Smart SpacesJunaid A. Chowdary, Seung-Kyu Park, Suk-Kyo HongWe present a recipe based service composition scheme in smart spaces. We discuss real time problems of highly synchronized and user customizable processes with the help of an example. On-the-fly Quality of Service (QoS) shows up as a major issue in such environment. Furthermore the QoS of a dynamically composed service depends upon the aggregate QoS of its developing components. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,760 accessesView PDFCite
