Research ArticleOpen accessIn the abstractInvestigation of the Dimensions Design Components for the Rectangular Indirect Resistance Electrical FurnacesSalah K. JawadProblem statement: The objective of this study was to study the Indirect Resistance Electrical Furnaces (IREF) based on analytical and experimental analyses. The analytical analysis focused on a constant set of equations representing the internal and external flow of heat energy in the furnace, which demonstrated, relatively with the surface area of walls, heat transferring inside the furnace chamber to … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmune Response and Pasteurella Resistance in Rabbits Fed Diets Containing Various Amounts of Black Cumin SeedsNabiela M. El Bagir, Imtitha T.O. Farah, Safia M.B. Elhag et al.Problem statement: The consumption of black cumin (Nigella sativa) seed has immunomodulatory and anti-bacterial activity, but in rabbits this had not yet been tested. Approach: In the present studies, rabbits were fed diets without or with black cumin seed and antibody production, phagocytotic activity, hypersensitivity and resistance against Pasteurellosis were assessed. Results: Feeding black cumin seed significantly increased serum concentrations … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistological Study of Cervix Uteri in Caspian Miniature HorseM. Rezaian, S. HamediProblem statement: Uterine cervix which separates the uterus from the vagina, shows remarkable anatomical and histological differences among mammalian species. Since no cleared observations have been found in regards with the Caspian miniature horses’ cervix, the aim of the present study was to supplement this missing information which could be helpful for providing a stricter basis in detecting reproductive diseases … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Coupled Mathematical Model for a Temperature Dependant Blood Perfusion in Heterogeneous Biological Tissues during Microwave HeatingE. A. Adebile, B. N. Akintewe, K. M. OwolabiProblem statement: The temperature variation in heterogeneous three layered biological tissues was investigated. Approach: The blood perfusion was considered to be temperature dependent. The heating modalities were taking to go on simultaneously in each of the regions on the one hand and also sequentially in another arrangement. The asymptotic series solution was modified for the three layers and the matching … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 6,580 accessesView PDFCite

Science and Research Branch of Islamic Azad University, Punak Tehran for approval and financial support to finish this project. Problems statement: The purpose of this research was to determine the biological effect of cartilage graft as a bone defect filler and osteogenetic stimulation to speed up … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,430 accessesView PDFCite
Research ArticleOpen accessIn the abstractNoise Control Using Coconut Coir Fiber Sound Absorber with Porous Layer Backing and Perforated PanelRozli Zulkifli, Zulkarnain, Mohd Jailani Mohd NorProblem statement: Noise control was one of the major requirements to improve the living environment. One of the methods to do that is provided by sound absorber. Commonly, multi-layer sound absorbers are applied to absorb broadband noise that was composed of perforated plates, air space and porous material. However, multi-layers sound absorbers effectiveness depends on their construction. This study was … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 14,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified Center Interpolation Net for Classification of Composite Structures Tested Using Low Frequency Electronic TappingMahmoud Z. IskandaraniProblem statement: Most exhaustive NDT techniques require large capital equipment, are difficult to apply to complex geometric structures and, above all, are time-consuming to use and some take a considerable time to complete. As a solution to the problems associated with NDT applications, there is a need to establish an intelligent analysis system that supports a portable testing environment, which … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Optimization of a 1.55 µm Waveguide Based on Silicon Planar Photonic CrystalsR. Bchir, A. Bardaoui, M. Machhout et al.Background: Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Objective: First, we varied the thickness of the Silicon slab and the pore radius in order to obtain optimum design parameters … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,461 accessesView PDFCite
