Research ArticleOpen accessIn the abstractConstruction of an Integrated Object Oriented System for Temporal GISSouheil Khaddaj, Abdul Adamu, Munir MoradThe development of temporal GIS systems capable of dealing with the evolution of geographical objects is still a challenging task. Although many successful GIS systems have been implemented, comparatively little has been done on how to determine and analyze the patterns of continuous changes of geographical objects. The aim of this paper is to construct a GIS system using an … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong Cycles in Employment, Inflation and Real Unit Wage Costs, Qualitative Analysis and Quantitative AssessmentPeter Flaschel, Goeran Kauermann, Timo TeuberThis study provided some theoretical foundations for the empirical hypothesis. At first presented two simple prototype models of inflation, stagflation and disinflation. We concluded that there are cycles with a phase length much longer than the ordinary business cycle (in fact approximately five times as long as we saw in the empirical phase plots of the paper) which are not … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 18 Dec 2005 · 8,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Geometry and Dimensionless Parameters on Heat Transfer Characteristics of a Closed–end Oscillating Heat-pipe at Vertical PositionS. Rittidech, K. PhalasinThis heat transfer characteristics of a closed-end oscillating heat-pipe (CEOHP) depend on a number of parameters. They are the number of turns, inner diameter of the tube, aspect ratio and the dimensionless parameters of heat transfer. The CEOHPs used to employ a copper tube with inner diameter of 0.66, 1.09 and 2.03 mm. The lengths of the evaporator, adiabatic and … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractEclecticism Beyond Orthodoxies: African Social Science Research in the Fight Against HIV/AIDSAmbe-Uva T. NomThis study examines the importance of social science research on HIV/AIDS in Africa. There is a dearth of social science research on HIV/AIDS epidemic in Africa as available literature focus essentially on biomedical and epidemiological aspect of HIV/AIDS research and behavioral changes. In Africa however, efforts at preventing and mitigating the impact of HIV/AIDS epidemic will have to consider the … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,973 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Different Doses of Irradiation on Oxidant and Antioxidant Systems in the Brain of Guinea PigsYildiz Guney, Ayse Bilgihan, Ayse Hicsonmez et al.The purpose of this study was to establish the impact of oxidative stress in the damaged brain tissue, irradiated with two different dose levels, a single dose of 8 and 15 Gy. In addition, the histological findings caused by ionizing radiation in the early period was investigated. The levels of MDA, GSH, SOD, CAT, GSH-Px and selenium were estimated in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthetic Pyrethroid Resistance in Field Strains of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) in Tamil Nadu, South IndiaP. Duraimurugan, A. RegupathyResistance to synthetic pyrethroids was diagnosed in the field population of American bollworm, Helicoverpa armigera (Hubner) from Coimbatore, Tamil Nadu, South India during 2003-2004 cropping seasons. A Discriminating Dose (DD) bioassay technique was used to monitor fortnightly changes in resistance at Coimbatore where number of crops served as host plants for this pest. The resistance level of various synthetic pyrethroids … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Routing Algorithm for Ad hoc Mobile NetworksHamed S. Al-BdourThis research has examined the issues of routing in multi-hop wireless networks of mobile nodes without the need for any existing network infrastructure or administration. This is called ad hoc. The key point of this research article are selecting routing protocols which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreased Production of Nitric Oxide Contributes to Renal Oxidative Stress in Endotoxemic RatBahar Tunçtan, Belma Korkmaz, Hatice Yıldırım et al.Overproduction of reactive oxygen and nitrogen species leads to oxidative stress and decreased total antioxidant capacity, which is responsible for high mortality from several diseases such as endotoxic shock. Nitric oxide (NO) produced by inducible NO synthase (iNOS) during endotoxemia is the major cause of vascular hyporeactivity, hypotension and multiple organ failure. In this study, we investigated whether increased production … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 8,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergetic Aspects Related to Heavy Metals Adsorption on the Surface of Volcanic Tuff I. The Influence of Activation Parameters in Cu2+ AdsorptionLeonard Mihaly-Cozmuta, Teodor Visan, Anca Mihaly-Cozmuta et al.The article develops some physico-chemical aspects presented along of copper ions adsorption in treatment of wastewaters using volcanic tuff. In the experiments volcanic tuff from Stoiana Pâglişa (Romania) has been used. Different concentrations of NaCl and HCl solutions were used for activation of tuff. The increase of activation solutions' concentrations indicates an intensification of specific adsorption of copper as consequence … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,675 accessesView PDFCite
