Research ArticleOpen accessIn the abstractDevelopment 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 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization of Soybean Mosaic Virus NIa Protein and its Processing Event in Bacterial ExpressionBong K. Choi, Jae S. Park, Hye J. Ahn et al.Soybean mosaic virus (SMV)-CN18 is an Rsv resistance-breaking (RB) isolate to overcome soybean resistance genes Rsv1, Rsv3 and Rsv4. The aim of this study was to characterize nuclear inclusion protein a (NIa protein) of RB isolate at the molecular level and demonstrate its processing into genome-linked protein (VPg) and NIa-Pro domains in Esherichia coli containing a bacterial expression pET vector … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,906 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Ranking Capability of the Hyperlink Based Search Engines Using Heuristic ApproachHaider A. Ramadhan, Khalil Shihab, Jafar H. AliTo evaluate the informative content of a Web page, the Web structure has to be carefully analyzed. Hyperlink analysis, which is capable of measuring the potential information contained in a Web page with respect to the Web space, is gaining more attention. The links to and from Web pages are an important resource that has largely gone unused in existing … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,382 accessesView PDFCite

Among them, waste management extension is highly significant because of the millions of tons of annual waste in vegetal, animal, environmental and natural resources products as well as millions of hectors … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractValidity and Reliability of the Short Form- 36 Items Questionnaire as a Measure of Quality of Life in Elderly Iranian PopulationSeyed-Reza Eshaghi, Mohammad Arash Ramezani, Armindokht Shahsanaee, Arash PooyaThe utility of The SF-36 questionnaire for evaluation of health related quality of life was not clear in elderly people. The Cross-Sectional study was designed and Iranian version of The SF-36 was administered to random sample of 100 old subjects over 60 years old. Finding showed good internal consistency over 0.7 for all subscales of questionnaire. Convergent validity was obtained … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractHarmonics Study and Comparison of Z-source Inverter with Traditional InvertersB. Justus Rabi, R. ArumugamThis paper presents an Impedance Source Inverter for A.C electrical drives. The impedance source inverter employs a unique impedance network cable with inverter main circuit and rectifier. By controlling the shoot-through duty cycle, the z-source inverter system using MOSFETS provide ride-through capability during voltage sags, reduces line harmonics, improves power factor and high reliability, and extends output voltage range. Analysis, … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Traffic Flow and Management at Un-signalized, Signalized and Roundabout Road IntersectionsR. Kakooza, L.S. Luboobi, J.Y.T. MugishaTraffic congestion continues to hinder economic and social development and also has a negative impact on the environment. A simple mathematical model is used to analyze the different types of road intersections in terms of their Performance in relation to managing traffic congestion and to establish the condition for stability of the road intersections after sufficiently longer periods of time … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractPressure-sensitivity Effects on Toughness Measurements of Compact Tension Specimens for Strain-hardening SolidsAbdulhamid A. Al-AbduljabbarThe path-independent J-integral is used as a fracture prediction criterion for loading beyond the elastic limit as Linear Elastic Fracture Mechanics (LEFM) cannot be applied. While J was originally defined from an energy perspective, it was demonstrated that it could be inferred from load-displacement diagrams. Therefore, the Compact Tension (CT) specimen testing is used to compute J for materials. In … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,660 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,792 accessesView PDFCite
