Research ArticleOpen accessIn the abstractModification of Carbon Steel by Laser Surface Melting: Part II: Effect of Laser Beam Power on Microstructural Features and Surface HardnessHashem F. El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe surface hardness has an important effect on the wear resistance of different materials. The present study aims to improve the surface hardness of carbon steel through the application of laser surface melting with suitable conditions. The laser beam power and travelling speed are the main factors that affect the properties of the treated zone. In this study, three different … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 30 Jan 2014 · 7,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Biological Dietary Feed Supplement for Laying Hens with Microelements Based on Duckweed (Lemna minor)Zuzanna Witkowska, Agnieszka Saeid, Katarzyna Chojnacka et al.In this study the applicability of enriched duckweed (Lemna minor) as a dietary supplement witch microelements is reported. In our previous studies, the technology of new feed additives with microelements based on duckweed biomass was elaborated. Here, we report the evaluation of the properties of a new product. The effect of duckweed enriched with microelements on the productivity parameters of … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 31 Jan 2013 · 8,549 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow-doping Effects of Nanostructure ZnO: Sn tin films annealed at different temperature in Nitrogen ambient to be applied as an Anti-reflecting coating (ARC)H. Abdullah, M.N. Norazia, S. Shaari et al.Problem statement: The focus of this research is to discover the significant influences of substituting low concentration Sn at Zn-site as an Anti-Reflecting Coating (ARC) for Zn1-xSnxO compound. The effects of tin dopants on the structural and morphology properties of ZnO thin films prepared using the sol-gel method were investigated. Approach: The effects of annealing temperature on the deposited films … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractNematic and Smectic Mesophase from Calamitic Bisazobenzene Liquid Crystal: Synthesis and Characterization of 1- Methoxyhexyloxy-4'-(4-Phenylazo) Azobenzene Hybrid MoleculeSidik Silong, Abdulsalam Abubakar Salisu, Muhamad Zaki Ab Rahman et al.A new hybrid calamitic liquid crystal material with rod-shape bisazobenzene moieties as a core has been synthesized and characterized by spectroscopic methods. The mesomorphic properties were investigated by differential scanning colorimetry, polarizing optical microscopy and X-Ray diffraction. The rod-shaped molecule 1- methoxyhexyloxy-4`-(4-phenylazo)azobenzene was prepared by diazotization of 4-phenylazoaniline, coupling with phenol and subsequent etherification of 1-Bromohexyloxy-4`-(4-phenylazo)azobenzene in methanol. The presence … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrostructural Study of Al-Si-Mg Alloy Reinforced with Stainless Steel Wires Composite via Casting TechniqueMazlee Mohd. Noor, Shamsul Baharin Jamaludin, Kamarudin HussinThe microstructural study of Al-Si-Mg alloy reinforced with stainless steel wires (Al-Si-Mg/SSw) has been investigated and focused on the both microstructures in the matrix and near to the interface and also the wetting condition at the interface. The wettability of solid metals by liquid metals is very important in determining the needed properties of the composite systems. In this study, … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,655 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Flexible, Real-Time Algorithm for Simulating Correlated Random Fields and Its PropertiesMichael A. Kouritzin, Fraser Newton, Biao WuContemporary real-time problems like CAPTCHA generation and optical character recognition can be solved effectively using correlated random fields. These random fields should be produced on a graph in order that problems of any dimension and shape can be handled. However, traditional solutions are often too slow, inaccurate or both. Herein, the Quick Simulation Random Field algorithm to produce correlated random … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 29 Sep 2017 · 7,069 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Vitamin A on Growth Performance, Antioxidant Status and Blood Constituents in Lactating Grey GoatWeiren Yang, Ping Wang, Yuanqiang Jing et al.Problem statement: It is regarded that vitamin A protects cells from damage by radicals which are believed to contribute to certain chronic diseases and regulates immune function of animals by protection of mucosal epithelium acting as the first defense barrier. All these properties of vitamin A may be attributable to its antioxidant activity. This study was to evaluate the effects … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,674 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effect of Electrical Properties by Texturing Surface on GaAs Solar Cell EfficiencyH. Abdullah, A. Lennie, M. J. Saifuddin, I. AhmadProblem statement: This project discusses on the method to resolve the optical losses problem that have been hindering the totality efficiency of the photovoltaic. Solar cell simulation could be useful for time saving and cost consumption. The Silvaco software is not widely used in designing the 2D solar cell devices because there is lots of 1D, 2D and 3D-simulation beside … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,785 accessesView PDFCite
