Research ArticleOpen accessIn the abstractThree Dimensional Hydrodynamic Model With Multiquadtree MeshesGregorio Posada Vanegas, Rodolfo Silva Casarín, Sébastien de BryeThis study presents a three dimensional model for the transport of conservative contaminants, which can be used for bodies of water which are affected by winds and/or tides. The model solves the equation of mass transport, based on results obtained using a hydrodynamic model for shallow waters that works in a finite volume scheme and a type of hierarchical grid, … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation Into The Behavior of Circular Pad Shallow Foundations Supported By Geogrid Reinforced SandS. M. Marandi, M. H. Bagheripour, R. Rahgozar, A. R. GhirianThis study seeks to widen the pool of knowledge on the use and characteristics of geosynthetics, specifically in the area of circular foundations supported by geosynthetic reinforced sand. The main objective of the work was to increase the awareness of circular foundation systems and thus increase the accuracy of current laboratory methods. Also, compare the results with that of previous … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat Transport Modeling in an Aquifer Downgradient a Municipal Solid Waste Landfill in ItalyRajandrea Sethi, Antonio Di MolfettaHeat generation inside municipal solid waste (MSW) landfills is due to aerobic and anaerobic exothermic reactions occurring inside the waste. The result of heat generation and transport inside sanitary landfill leads to a temperature field that varies from mesophylic range (optimum at 30-40°C) to thermophylic range (optimum at 50-60°C). Due to high temperatures at the bottom of the landfill, liner … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element and Experimental Serviceability Analysis of HSC Beams Strengthened with FRP SheetsSeyed Hamid Hashemi, Reza Rahgozar, Ali Akbar MaghsoudiThe use of externally bonded composite sheets or laminates is by now a diffuse technique to strengthen existing RC structures. However, some aspects of flexural condition still need experimental and numerical analysis; furthermore, especially for serviceability checks, there is a lack of code provisions. Six reinforced high strength concrete (HSC) beams strengthened with FRP sheets were fabricated and tested, the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,977 accessesView PDFCite
Research ArticleOpen accessIn the abstractHiding a Large Amount of Data with High Security Using Steganography AlgorithmNameer N. EL-EmamThis study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 8,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffective Coagulation Technology for Treatment of Grease Filter WashwaterAbdel E. Ghaly, A. Snow, B.E. FaberThe treatment of grease filter washwater by chemical coagulation and sedimentation using different dosages of aluminum sulfate was investigated. Pollutant removal efficiency was measured in terms of total solids, pH and optical density. The process was found to be effective at the room temperature and the filter washwater pH (9.5). The optimum aluminum sulfate dosage was 2 g/L. The treatment … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 6,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Vibration Analysis of a Cross-Ply Laminated Composite Beam on Pasternak FoundationR. A. Jafari-Talookolaei, M. T. AhmadianIn this study, free vibration analysis of a cross-ply laminated composite beam (LCB) on Pasternak foundation was investigated. Natural frequencies of beam on Pasternak foundation are computed using finite element method (FEM) on the basis of Timoshenko beam theory. Effect of both shear deformation and rotary inertia are implemented in the modeling of stiffness and mass matrices. The model was … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformatics and Physics Models of Recognitions of DNA Replication and Their Biological ApplicationsKang Cheng, Chang Hua ZouWe initially propose concepts of Informative Intensity, Informative Response Intensity and Informative Flux, with different expressions. In a special expression of electrostatics, we describe Informative Intensity, Informative Response Intensity and Informative Flux in terms of electric field intensity, electric field force and electric field flux respectively. In a special expression of quantum mechanics, we originally propose a concept of Probability … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,873 accessesView PDFCite
