Research ArticleOpen accessAll words, across the recordEvaluation and Beneficiation of Bentonitic Clays from Pindiga Formation in Benue TroughB. B.M. Dewu, I. I. Funtua, M. O.A. Oladipo et al.Problem statement: This study aimed at evaluating and beneficiating Bentonitic clays of Pindiga Formation from the upper Benue trough in northeastern Nigeria to meet the standard required for use in oil well drilling. This will reduce the dependence on imported Bentonite into the country, increase foreign exchange, improve the country’s economy and create employment opportunities. Approach: Three clay samples from … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 16 Jan 2012 · 8,566 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordGeneralization Aspect of Neural Networks on Upgrading Assimilation Structure into Accommodating SchemeWaleed, A. J. Rasheed, Hamza A. AliProblem statement: Generalization feature enhancement of neural networks, especially feed forward structural model has limited progress. The major reason behind such limitation is attributed to the principal definition and the inability to interpret it into convenient structure. Traditional schemes, unfortunately have regarded generalization as an innate outcome of the simple association, referred to by Pavlov and had been modeled by … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,149 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDevelopment and Early Score Validation of the Malaysian Educator’s Information Technology Attitude Scale (MEITAS)Wong Su LuanThe purpose of this study was to develop and provide initial validation evidence for an instrument to measure educators’ attitudes toward IT. Data were collected from 817 participants comprising both pre and in-service teachers in four phases. Two separate factor analyses were conducted for the pre-service teacher data and in-service teacher data. Principle component analysis, with varimax rotation, suggested three … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,204 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Development of A New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part I: Design of the Detection System and ApplicationsEric Carnes, Ebtisam WilkinsA portable, flow-through amperometric immunoassay system utilizing a newly designed immunosensor has been developed for the detection of bacteria. A sandwich scheme of immunoassay involving two stages of immunoreaction was employed using Escherichia coli as a model. E. coli antibodies were immobilized on Toray carbon paper to create a disposable immunofiltration membrane. Detection of the bacteria was achieved through the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2006 · 6,363 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,868 accessesView PDF Cite
