Research ArticleOpen accessIn the abstractBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Bio-Oil into High-Value Hydrocarbons via HydrodeoxygenationMurni M. Ahmad, M. Fitrir R. Nordin, M. Tazli AzizanProblem statement: World energy consumption is forecasted to grow significantly for the foreseeable future with fossil fuel remains the governing energy source. The demand in the need to explore alternative fuel source was further triggered by the overwhelmingly inconsistent cost of gasoline. Bio-oil is an alternative energy source produced from pyrolysis of biomass. However it is undesirable as a ready … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractMitochondrial Energy-Deficient Endophenotype in AutismJ. Jay Gargus, Faiqa ImtiazWhile evidence points to a multigenic etiology of most autism, the pathophysiology of the disorder has yet to be defined and the underlying genes and biochemical pathways they subserve remain unknown. Autism is considered to be influenced by a combination of various genetic, environmental and immunological factors; more recently, evidence has suggested that increased vulnerability to oxidative stress may be … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 11,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractIR Laser Plasma Interaction with GlassRabia Qindeel, Noriah Bidin, Yaacob Mat DaudThe interaction of laser plasma with respect to glass surface is reported in this paper. A Q-switched Nd:YAG laser was used as ablation source. Glass material is utilized as target specimen. Aluminum plate is used as a rotating substrate. The dynamic expansion of the plasma was visualized by using CCD video camera and permanently recorded via image processing system. The … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Flow Structure of A Thermal Plume Evolving in an Unlimited and in A Semi-Enclosed EnvironmentJamil Zinoubi, A. Ould Mohamed Mahmoud, Taoufik Naffouti et al.The basic objective of this study was to better knowledge the fine flow structure of thermal plume created by a heated disk, evolving in an unlimited and in a semi-enclosed environment. The flow visualization and the study of the temperature fluctuations spectrum show clearly a considerable change of the turbulent structure of the internal flow in comparison with the free … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Geothermal Energy Potential of Ruwan Zafi, Adamawa State and Environs, Northeastern Nigeria, using High Resolution Airborne Magnetic DataIbe Stephen Onyejiuwaka, Uche Kelvin IdumaThe aeromagnetic dataset over Ruwan Zafi, Adamawa State and environs, Northeastern Nigeria, was interpreted in this study, in order to map out places with the potentials for application of geothermal energy for electricity generation and geothermal direct heating. The analysis of the spectral of the magnetic dataset delineated the range of the sediment thickness as 4273.58 and 8693.32 m and … …Current Research in Geoscience, Vol. 10, Issue 1 · 4 Dec 2020 · 12,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Modeling the Prosthetic Foot from Suitable Composite MaterialsHasan Saad Mohammed, Jasim Mohammed SalmanThis work concerns developing a composite material, which can be used in manufacturing prosthetic feet with a reasonable cost and satisfying mechanical properties. The characteristics were investigated by mechanical tests of tensile properties and Charpy impact strength. The study of date palm wood and its effects on the mechanical properties of polyethylene have received little attention. It was found that … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 12 Sep 2020 · 7,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractComprehensive Investigation into the Exergy Values of Six Rice HusksYaning Zhang, A.E. Ghaly, Bingxi LiExergy is a measurement of how far a certain system or material deviates from a state of equilibrium with the environment and it is a useful tool for improving the efficiency of energy-resource use. Based on the previous work, the exergy values of six rice husks were investigated in this study. The effects of physical and chemical properties were also … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 10 Jun 2013 · 7,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Wheat Straw Varieties Cultivated Under Different Climatic and Soil Conditions in Three ContinentsYaning Zhang, A. E. Ghaly, Bingxi LiOver 500 million tonnes of wheat straw are produced annually worldwide, the majority of which are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to loss of a valuable resource. Wheat straw is abundantly available and renewable and can be used as an energy source in gasification and combustion systems. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 26 Jun 2012 · 21,096 accessesView PDFCite
