Research ArticleOpen accessIn the abstractA New Architecture for Improving Location Management in PCS NetworksHaidar Safa, Samuel PierreThis study proposes a new architecture for improving the location management in PCS networks. The proposed architecture employs several HLRs as opposed to one HLR in the IS-41 and GSM models. Indeed, the new architecture associates with each MU two types of HLRs ; a resident HLR that serves the location areas in which the MU often resides and a … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiology and Seasonal Pattern of Malaria in an Irrigated Area of Eastern SudanYousif El-Safi Himeidan, Efatih. M. Malik, Ishag AdamEpidemiological patterns of malaria are widely different; such information can help programs to design interventions relevant to situation. This cohort study investigated the epidemiology of malaria in Dipaira camp, an irrigated area, in eastern Sudan during the period July 2004 to Jun 2005. At baseline, the relevant socio-demographic factors and the monthly malaria parasitological surverys were carried-out. Thirty- six (4.1%) … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractHumoral Immune Response in Tuberculous PleuritisPrabha C., Kripa V. Jalapathy, Sulochana D. DasTuberculous pleuritis is a good human model to understand the local and protective immune response against tuberculosis, due to the self-limitedness of the disease. Although the cellular immune response has been well characterised in tuberculous pleurisy, much less is known about the humoral immune response operating at the site of infection. To understand the humoral immune response, B cells were … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Gamma Irradiation on the Structure Diffusion Coefficient of Co-Zn Doped FerriteDalal Mohammed HemedaA series of the ferrite system Co0.6Zn0.4MnxFe2-xO4 with (x = 0.7, 0.8, 0.9 and 1) were prepared by general ceramic method. The X-ray diffraction patterns confirmed the formation of the cubic single phase structure. The lattice parameter and the crystal size increased after irradiation which was attributed to the formation of ferrous ions of larger radius than that of ferrous … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,728 accessesView PDFCite

Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite
