Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Chemical Admixtures on the Engineering Properties of Tropical Peat SoilsBujang B.K. Huat, Thamer A. Mohamed, Shukri MaailThis research describes a study on the effect of chemical (cement and lime) admixtures on the index and engineering properties (compaction and unconfined strength) of tropical peat soils. The ordinary Portland cement and hydrated lime were used. The amounts cement and lime added to the peat soil sample, as a percentage of the dry soil mass was in the range … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Pressure Pulses in the Jerk Fuel Injection SystemsR. A. Baker, T. FirozComputer software has been developed and described in the present study of thorough parametric analysis and design of a mechanical diesel fuel injection system. The method is based on the numerical solution of one dimensional, unsteady, incompressible flow equations through the fuel pipe along with appropriate initial condition, pump end boundary condition and nozzle end boundary condition. Method of characteristics … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Vibrations in Switched Reluctance Motor DrivesS. Balamurugan, R. ArumugamThis study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Geosta Addition on Cement-stabilised Chicoco Mud of the Niger DeltaOlujide OmotoshoChicoco is a very soft and extremely compressible organic marine mud found extensively and to considerable depths within the saline tidal flat or mangrove swamp of the Niger delta in southern Nigeria. Natural chicoco is highly undesirable, barely able to support a human of average weight but air-dried chicoco has been used successfully by the indigeneous people for shore protection, … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Optimal Medium in Which the ‘Celalettin-Field Quantum Observation Tunnel’ Operates: The Polarised Electron Cloud’s Emergence from the Laboratory Based Rubidium-87 to Helium-3; InvizicloudMetin Celalettin, Horace KingThis study discusses the previously mentioned Polarized Electron Cloud, its progression to ‘INVIZICLOUD’ as in the real word Rubidium-87 can only be used in the lab, whereas the molecule that is INVIZICLOUD© is made of is Helium-3 mixed with an atomic inert alkaline. It is the medium in which the ‘Celalettin-Field Quantum Observation Tunnel’ (CFQOT) operates. When a quantum qubit … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 21 Mar 2019 · 8,350 accessesView PDFCite
