Research ArticleOpen accessAll words, across the recordINVESTIGATING EFFECTS OF INTRODUCTION OF CORNCOB ASH INTO PORTLAND CEMENTS CONCRETE: MECHANICAL AND THERMAL PROPERTIESAntonio Price, Ryan Yeargin, Ellie Fini, Taher Abu-LebdehThe purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC) with Corncob Ash (CCA) blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2) emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO) from limestone (CaCO3) commonly known as … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 31 Mar 2014 · 9,813 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEFFECTIVE BLACK HOLE ATTACKS IN MANETSRaja Azlina Raja Mahmood, Zurina Mohd Hanapi, Sazlinah Hasan, AsadIqbal KhanBlack hole or packet drop attack is a denial of service attack on routing protocols in which malicious nodes fabricate routing information, attract packets routed through them and then deliberately drop these packets. Most of the black hole attack simulations are performed by constantly fabricating routing information and thus consistently attracting packets to them, which can be easily detected by … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,932 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTWO PHASE CLUSTERING METHOD FOR LEACH PROTOCOL FOR EFFECTIVE CLUSTER HEAD SELECTIONRathi, ViswanathanA Wireless Sensor Networks (WSN) comprise of a huge quantity of clusters of sensor nodes that can inter communicate with all nodes and with the base station through a wireless link. All clusters are corresponding to a cluster head to provide a direct communication to the base station and in addition with other cluster heads. Obviously well-organized selection of cluster … …Journal of Computer Science, Vol. 10, Issue 3 · 21 Nov 2013 · 7,122 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,836 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLeptospirosis in the Tropics: When Prevention Doesn't Easily Sell as a Ton of CureRoger Lee MendozaProblem statement: Human leptospirosis -- the most widespread zoonotic disease -- thrives in tropical and subtropical climates. It is seldom addressed ex ante or prior to an outbreak or expected outbreak by governments of high-risk countries. Whether common, post-exposure treatment with antimicrobial drugs is more cost-efficient than reducing animal reservoir populations was the overarching question that guided this study. A … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 8,378 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Quercetin Encapsulated Liposomes via Nasal Administration: A Novel Cognitive EnhancerTerdthai Tong-un, Supaporn Muchimapura, Wathita Phachonpai, Jintanaporn WattanathornProblem statement: Demand for cognitive-enhancing drugs is growing. Numerous medicinal plants possessing antioxidant activity have received much attention as food supplement to improve cognitive function. Quercetin is a potent free radical scavenger and antioxidant. However, the limitations of quercetin: Rapidly metabolized is an obstacle to its use for a cognitive enhancer. In addition, the burden of blood brain barrier can … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,498 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Supplemental Lysine and Methionine on Growth Performance and Body Composition for Grass Carp (Ctenopharyngodon idella)Hui Jun Yang, Yong Jian Liu, Li Xia Tian et al.Problem statement: The utilization of crystalline amino acids was detected for growth performance and body composition of juvenile grass carp (Ctenopharyngodon idella). Approach: L-Lysine sulphate and Methionine Hydroxy Analog-Ca (MHA-Ca) were selected for determination. Two diets were formulated with or without amino acids supplementation. Each diet was assigned to 10 tanks in a completely randomized design for 8 weeks. Results: … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,657 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSingle Beam Z-Scan Measurements of Nonlinear Refraction and Nonlinear Absorption Coefficients in Silver Nano-FluidEsmaeil Shahriari, W. Mahmood Mat YunusProblem statement: The nonlinear refractive index and nonlinear absorption are two important optical phenomena which are extensively used in optical switching, optical limiting and labeling. Approach: In the present research we had measured nonlinearity of Ag nano-fluid prepared using γ-irradiation method. The measurement was carried out using a single beam z-scan technique. Under a CW laser beam excitation operated at … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,635 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Blood Turbulent Flow in Carotid Artery Including the Effects of Mural Thrombosis Using Finite Element ModelingM. Arab-Ghanbari, M. M. Khani, A. Arefmanesh, F. Tabatabai-GhomsheArterial thrombosis is an extremely significant health problem. As a result of numerous factors involved in such problem, describing the role of hemodynamics in thrombogenesis has been asserted to be one of the most demanding and complicated challenges in biomechanics. An axisymmetric model considering fluid-structure interactions (FSI) was introduced and numerically solved for an artery with a thrombosis to perform … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,408 accessesView PDFCite
