Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effectiveness of Quality Circle Participation in Industrial and Service Organizations in MalaysiaT. R. Abo-Alhol, M. Y. Ismail, S. M. Sapuan, M. M. HamdanQuality Circle (QC) proponents suggest a wide array of positive results when this participation technique is used either in manufacturing or in service sector. This study is to determine whether QCs in one sector are performing more effectively than the other. This assessment includes technical aspects, length of participation, training, members' feelings about QCs, job satisfaction and job commitment. The … …Journal of Social Sciences, Vol. 1, Issue 1 · 6 Mar 2005 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractED-XRF Analysis of Total Suspended Particulates from Enamelware Manufacturing IndustryJ. A. Sonibare, F. A. Akeredolu, O. Osibanjo, I. LatinwoConcentration and elemental composition of the total suspended particulates (TSP) emitted due to manufacturing activities of an enamelware industry in Lagos, Nigeria were investigated. Gravimetric method was used in mass concentration determination and an energy dispersive x-ray fluorescence (ED-XRF) analyzer was employed in the multi-elemental analysis. The Federal Ministry of Environment (FMENV, Nigeria's environment regulating body) set limit of 250 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Cellulase from Oil Palm Biomass as Substrate by Solid State BioconversionMd. Z. Alam, Nurdina Muhammad, Mohd E. MahmatSolid state bioconversion (SSB) of lignocellulosic material oil palm biomass (OPB) generated from palm oil industries as waste was conducted by evaluating the enzyme production through filamentous fungus in lab-scale experiment. OPB in the form of empty fruit bunches (EFB) was used as the solid substrate and treated with the fungus Trichoderma harzianum to produce cellulase. The results presented in … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,440 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 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of the Effect of Aspect Ratio on the Airfoil PerformanceM. Kopaç, M. Yılmaz, T. GültopThe effect of aspect ratio on the airfoil performance is investigated for airflow about axially symetric wings as a function of the angle of attack. The magnitudes of aerodynamic forces and moments on airfoils resulting from the incompressible viscous flow fields are determined experimentally. The TE54 wind tunnel used for the experiments is an open conduit and has a 300x300 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,682 accessesView PDFCite

SapuanIn this study, a study of conceptual design for the polymeric-based composite automotive pedal box system is presented. This study describes the importance of the concurrent engineering technique in the total design activity. Several idea generation methods like the extension of the search space, the morphological chart, the exploitation of experiences, the gallery method and the voice of customer had … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Cellulosic Membrane Containing Pyrrolidone Moiety Via Radiation Induced Grafting and its Application in Wastewater TreatmentA. S. Aly, H. H. Sokker, A. Hashem, A. HebeishRadiation induced grafting of vinyl pyrrolidone onto cellulose wood pulp was carried out in heterogeneous and homogenous media using gamma radiation. Cellulose wood pulp was used in different forms; a) in a homogenous solution by dissolving the wood pulp in N,N- dimethylacetamide/Lithium chloride (DMAc/LiCl) mixture , b) in a membrane form, by precipitating the cellulose solution in water and c) … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy and Carbon Flux Coupling: Multi-ecosystem Comparisons Using Artificial Neural NetworkAssefa M. Melesse, Rodney S. HanleyA multi-ecosystems carbon flux simulation from energy fluxes is presented. A new statistical learning technique based on Artificial Neural Network (ANN) back propagation algorithm and multi-layer perceptron architecture was used in the CO2 simulation. Four input layers (net radiation, soil heat flux, sensible and latent heat flux) were used for training (calibration) and testing (verification) of model outputs. The 15-days … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew.
