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 · 6,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Reconstructed Basins Using Pattern Spectrum ProcedureP. RadhakrishnanSeveral classical and Fractal binary shapes, which are akin to geophysical shapes such as basins, lakes, and pore-grain spruce, are analyzed and characterized by employing various mathematical morphological transformations, and methods. By employing rhombus, square and octagon structuring elements, these shapes are decomposed into their skeletal networks and their corresponding skeletal network subsets are dilated to the respective degree by … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractOOST: An Object Oriented Tool for Satellite Orbit DesignA. A. Salem, M. Zaki, A. A. WahdanIn this study the problems of satellite orbit design and simulation are tackled and an object oriented satellite tool OOST is developed. The tool with its three main modules enables the user to plan and design different satellite missions. It performs all orbital calculations needed, simulates the target orbit and performs analysis on the current active satellite(s). The simulation module … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Light Weight Ceramics Teils from Local MaterialsGhazi Al-MarahlehThis study covers the feasibility of production lightweight ceramics teils (light weight clay bricks) by adding local various types of combustible materials to the clay. It was found those substantial quantities of bagasse, sawdust, rice husks and straw are suitable for the production of lightweight bricks and distributed combustible materials finely was mixed with clay and molded into bricks. During … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring Water Quality Parameters of the Transboundry River NestosPsilovikos Aris, Margoni Sophia, Psilovikos AntoniosThe Nestos/Mesta river, shared by Greece and Bulgaria, needs monitoring system along its course for sustainable management and environmental preservation. Such a system, known as R.E.MO.S., was installed in the year 2000 and operates since then on a 24 h basis at a station in the river deltas channel. It records water level, water and air temperature, conductivity, redox potential … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractScheme for ISDN/DECT Wireless Internetworking and VerificationMaher Dababneh, Ibrahim QatawnehA novel scheme to access the basic rate service of the Integrated Service Digital Network (ISDN) using the Digital Enhanced Cordless Telephone (DECT) radio interface standard is presented. The S-interface in the ISDN reference configuration has been used for the ISDN interface and the unprotected class 0 transmissions are used for the DECT interface. The design of a state of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn a Problem Connected with Navier-stokes Equations in Non Cylindrical DomainsJ. Limaco, S. B. de Menezes, C. Vaz, J. F. MontenegroIn this study we showed the existence of weak solutions of equations that represent flows of a non-homogeneous viscous incompressible fluids in a non cylindrical domain in R3 . The classical Navier-stokes equation is a particular case of the equations here considered. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,610 accessesView PDFCite
