Research ArticleOpen accessIn the abstractThe Preparation and Investigation of Magnetic Properties of Magnesium Zinc ferritesA. Rittidech, N. Sinthorn, A. NoisaguanMg0.7Zn0.3Fe2O4 (MZF) is a ferrites material, displaying interesting magnetic properties. It has a wide range of magnetic coils and electronic devices. In this research, MZF ceramics was prepared by solid state reaction route and interested on sintering temperature that have effective on phase formation of MZF, microstruce and magnetic properties. The phase identification of ceramic ferrites was performed using X-ray … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies on Metal Microbe Interaction of Three Bacterial Isolates From East Calcutta WetlandV. K. Adarsh, Madhusmita Mishra, Sanhita Chowdhury et al.The present paper put forth the isolation and complete characterization of three bacterial isolates from different sites of East Calcutta Wetland (ECW). These isolates show tolerance to heavy metals like Ag, Al, Cu, Cr, Co, Ni, Pb and were found to be efficient metal accumulators as evident from Energy Dispersive X Ray Fluorescence (EDXRF) analysis and Transmission Electron Microscopy (TEM). … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 9,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractShed Skin of Ophiophagus hannah: Structural Topography and In Vitro Permeation of Nicotine and PhenolA. Priprem, T. Pongjanyakul, C. Khamlert et al.Scales of the dorsal portions of shed skin of king cobras (Ophiophagus hannah) was used as the barrier membrane for in vitro permeation of nicotine and phenol at toxic or irritable concentration levels. The scales were placed between solutions of nicotine or phenol in a donor solution at pH 5.6 and a receptor solution at pH 7.4. Cumulative amounts of … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractIR Laser Plasma Interaction with GlassRabia Qindeel, Noriah Bidin, Yaacob Mat DaudThe interaction of laser plasma with respect to glass surface is reported in this paper. A Q-switched Nd:YAG laser was used as ablation source. Glass material is utilized as target specimen. Aluminum plate is used as a rotating substrate. The dynamic expansion of the plasma was visualized by using CCD video camera and permanently recorded via image processing system. The … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Spatial ARM (Spatial Association Rule Mining) for Geo-Decision Support SystemRanjana Vyas, Lokesh Kumar Sharma, U. S. TiwaryGeographical Decision Support System (Geo-DSS) is a demanding field, since enormous amount of spatial data have been collected in various applications, ranging form Remote Sensing to GIS, Computer Cartography, Environmental Assessment and Planning. Although some efforts were made to combine spatial mining with Spatial Decision Support System but mostly researchers for spatial database are using a popular data mining approach-Apriori … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Arabic Hand Written Text Recognition SystemIsmael Ahmad JannoudDespite of the decent development of the pattern recognition science applications in the last decade of the twentieth century and this century, text recognition remains one of the most important problems in pattern recognition. To the best of our knowledge, little work has been done in the area of Arabic text recognition compared with those for Latin, Chins and Japanese … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Different Image Sizes for Recognizing Unconstrained Handwritten Tamil Characters using SVMN. Shanthi, K. DuraiswamyThis study describes a system for recognizing offline handwritten Tamil characters using Support Vector Machine (SVM). Data samples are collected from different writers on A4 sized documents. They are scanned using a flat bed scanner at a resolution of 300 dpi and stored as grey scale images. Various preprocessing operations are performed on the digitized image to enhance the quality … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlatelet Derived Growth Factor-A mRNA Levels in Diabetic and Nondiabetic Subjects at Risk of Coronary Heart DiseaseSalman A.H. AlrokayanCoronary heart disease (CHD) is the number one cause of death in developed countries. We investigated the quantity of platelet derived growth factor-A mRNA (PDGF-A mRNA) among four different groups of diabetic and nondiabetic Saudi subjects (n = 40) at risk of CHD. Total RNA was derived from peripheral blood mononuclear cells (PBMN) and PDGF-A mRNA reverse transcribed into cDNA … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,502 accessesView PDFCite
