Research ArticleOpen accessEvery word in the titleA New Method of Generating Index Label for Dynamic XML DataJayanthi Paramasivam, Tamilarasi AngamuthuProblem statement: The processing of the XML queries needs an efficient indexing method. The index generation includes the labeling of the nodes. But for the dynamic data, when the changes are made, the re-computation of the labeling is needed. Approach: Based on the structural indexing used the performance of the query processing system will be affected. The dynamic XML document … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,835 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAccurate Determination of Nonlinear Refractive Index for Some Binary Glass SystemsElSayed MoustafaProblem statement: This study investigates the relation between the nonlinear optical susceptibility (χ(3)) and the ratio (α1/αo-2), then the nonlinear index determination for some binary glass systems. Recently suitable relationship between the oxidation polarizability and the nonlinear optical properties was established for simple oxides glasses. So in this study more attention and investigation is paid to the trend of that … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,692 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,546 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Specific Index for Measuring the Association between Periodontal Conditions and Coronary Artery DiseaseNavabi Nader, Farzaneh MehdizadehProblem statement: There is increasing evidence that periodontal disease could play a role in the Progression of coronary heart disease although there are conflicting results about this association in the literature and the difference of used periodontal scoring systems among the studies might be a reason. The purpose of this study was to evaluate a specific scoring system Periodontal Index … …Current Research in Dentistry, Vol. 1, Issue 1 · 30 Jun 2010 · 8,019 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalytical Studies on Water Quality Index of River LandzuJ. Yisa, T. JimohProblem statement: River Landzu is of particular importance in the study of surface water pollution because effluents from cottage industries, municipal sewage, agricultural and urban run-off are discharged into it bringing about considerable change in the water quality. Approach: This study aimed at using the application of Water Quality Index (WQI) in evaluating the quality of River Landzu for public … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 11,612 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Influence of pH on Nonlinear Refractive Index of Bromophenol BlueF.Z. Henari, K.G. CulliganProblem statement: Bromophenol blue is a pH indicator, a kind of chemical that changes colour when pH goes up or down over a narrow linear dynamic range of 3.0-4.6 pH units. Therefore a good approach must be taken to extend the linear response of the indicator in order to have simple calibration and precise measurements of PH sensors. The purpose … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,948 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Distance and Heterosis through Evaluation Index in the Silkworm, Bombyx mori (L.)Ebrahim Talebi, G. SubramanyaProblem statement: Synthesis of new-gene combinations by genetic manipulation is one of the powerful tools in exploiting the commercial qualities of plants and animals. Hybrid performance is evaluated from extensive yield trials that are costly and time consuming. Approach: Four silkworm races belonging to two different voltine groups (two multivoltine races namely Pure Mysore and Nistari and two bivoltine races … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,157 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Damsites Groutability Using Secondary Permeability Index, Rock Classification (Case Studies)R. Ajalloeian, F. MoeinProblem statement: The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. There fore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid negative seepage pressure in borrow materials, so grouting is used. Grouting means injected materials like cement … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,411 accessesView PDFCite
