Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractLONG-REACH OPTICAL ACCESS NETWORKS (LR-OANS): A PROMISING CANDIDATE FOR FUTURE OPTICAL ACCESSI.M.M. Mohamed, M.S. Ab-RahmanThe ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, creates the motivation to upgrade the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs). Beside the need for more bandwidth per user, a further extension in the range and an increase in the split … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Aug 2014 · 6,704 accessesView PDFCite

Research ArticleOpen accessIn the abstractDESIGN AND DEVELOPMENT OF A RECOMMENDER SYSTEM FOR E-LEARNING MODULESBaseera, SrinathExtensive literature review revealed that, different recommender systems for E-learning were developed. A preliminary version of the development was undertaken and evaluated in an experiment during an introduction psychology course in an open university. The activities were integrated in to a model which operates on a network. No curriculum structure was assigned and the users were allowed to undergo learning … …Journal of Computer Science, Vol. 10, Issue 5 · 26 Dec 2013 · 7,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of E100 to Fuel a Used 4-Stroke MotorcycleT. SuthisripokProblem statement: Though ethanol and gasohol are proved to be used as alternative fuels in vehicles, 4-stoke motorcycles used nationwide mainly consumed gasoline 91/95. Approach: The motorcycle tested, the used Honda Wave125 model, was properly tuned at the rich relative air-fuel ratio (λ) 0.85, which theoretically gave the maximum power output. For the use of E100, the engine required richer … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 23 Feb 2012 · 9,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomarkers of Oxidative DNA Damage and Soluble Fas/Fas Ligand in Type 2 Diabetic PatientsMohamed H. Mahfouz, Ibrahim A. Emara, Ghada A. OmarProblem statement: Involvement of oxidative stress in the pathogenesis of diabetic complications has been proposed. 8-hydroxy-2'-deoxyguanosine (8-OHdG) has been reported to serve as a new sensitive biomarker of the oxidative DNA damage in vivo. Apoptosis via Fas/Fas Ligand (FasL) interactions has been proposed to be a major T-cell-mediated effector mechanism in autoimmune diabetes. This study was undertaken to investigate whether … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 3 Feb 2012 · 7,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,772 accessesView PDFCite
