Research ArticleOpen accessIn the abstractPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Garbage Sorting MachineStephen Kwasi Adzimah, Simons AnthonyProblem statement: Domestic waste collection, sorting and disposal are major problems in many developing countries such as Ghana. It is an undeniable fact that the environment has been engulfed in filth. This filth comprises of the garbage and waste generated in homes, workplace and industrial setups. Most of this waste has found its way into the streets, gutters, in and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Time Variation on the Wear Sliding Behavior of CompositesWafaa M. Salih, Sanaa M. Salih, Myada M. SalihComposites materials are widely used in all industries all over the world, replacing many other engineering materials. Reasons for such popularity are many, among such, are their physical and mechanical properties in addition to the simplicity of their manufacturing processes. Machine elements that are made of polymeric materials are usually exposed to different causes of failure such as wear. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing the Urea-N Use Efficiency in Maize (Zea mays) Cultivation on Acid Soils using Urea Amended with Zeolite and TSPOsumanu Haruna Ahmed, Aminuddin Hussin, Husni Mohd Hanif Ahmad et al.Problem Statement: Ammonia loss significantly reduces urea-N use efficiency in crop production. Efforts to reduce ammonia loss are laboratory oriented, as such limited in reflecting actual field conditions. This paper reports the effects of urea amended with triple superphosphate (TSP) and zeolite (Clinoptilolite) on soil pH, soil nitrate, soil exchangeable ammonium, dry matter production, N uptake, fresh cob production and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeating Effects on Structural and Electrical Properties of PolyetherimideNissaf Mzabi, Hichem Smaoui, Hajer Guermazi et al.Problem statement: Polyetherimide (PEI) has several uses such as electrical insulation. It can undergo different constraints like heat or high voltage which influence its performances as insulator. In this study, the effects of heating on structural and electrical properties of polyetherimide (Ultem 1000) are studied. Approach: PEI samples were heated at different temperatures below the glass transition temperature (175, 190 … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Manufacturing Stresses to Die Attach Film Performance In Quad Flatpack No-Lead Stacked Die PackagesM. F. Rosle, I. Abdullah, S. Abdullah et al.Problem statement: Repeated heat cure during assembly processes affected the Die Attach Film (DAF) material properties and the effectiveness touched area that leads to weak die bonding and delamination. Suitable die attached condition and DAF material selection had been evaluated to achieve required reliability performance in the manufacturing of the 3D Quad Flat No-Lead (QFN) stacked die package. Approach: During … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength Modeling of Reinforced Concrete Beam with Externally Bonded Fibre Reinforcement Polymer ReinforcementN. Pannirselvam, P.N. Raghunath, K. SugunaThis research study presents the evaluation of the structural behaviour of reinforced concrete beams with externally bonded Fibre Reinforced Polymer (FRP) reinforcements. Three different steel ratios with two different Glass Fibre Reinforced Polymer (GFRP) types and two different thicknesses in each type of GFRP were used. Totally fifteen rectangular beams of 3 m length were cast. Three rectangular beams were … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,485 accessesView PDFCite
