Research ArticleOpen accessIn the abstractSustainable Development through Waste Heat RecoveryP. S. Bundela, Vivek ChawlaProblem statement: Waste Heat Recovery (WHR) steam Technology is a proven Technology pioneered by Japanese for cement plant and it is economically viable. Electrical Power can be generated by adopting the latest technology in this field. It used a medium to low temperature (120-350°C) Turbine technology (standard thermal power plants run on steam temp-500°C). Approach: It requires treat exchangers (Hx) … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Single-Pass Photovoltaic-Thermal Air Collector with Rectangle Tunnel AbsorberGoh Li Jin, Adnan Ibrahim, Yee Kim Chean et al.Problem statement: Photovoltaic solar cell generate electric by receiving sun light or solar irradiance. But solar cell received heat from solar irradiance as well and this will reduced the efficiency of the solar cell. The heat trap at the solar photovoltaic panel become waste energy. Approach: The solution for this was by adding a cooling system to the photovoltaic panel. … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Programmable Gate Array -Based System-on-Chip for Real-Time Power Process ControlAhmed Karim Ben Salem, Slim Ben Othman, Slim Ben SaoudProblem Statement: Nowadays Real-Time (RT) embedded control applications require not just higher performance but more flexibility as well without increasing cost and resources. Approach: In this study we presented a promising co-design and implementation of control solution. We developed flexible solution using software control algorithms coupled with an embedded RT kernel on powerful embedded processor cores, combined with reconfigurable logic … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Variability of Irrigation Water Percolation Rates and Its Relation to Rice ProductivityW. Aimrun, M.S.M. Amin, A. GholizadehProblem statement: Study on spatial variability of vertical saturated hydraulic conductivity or percolation loss was conducted within a plot of an area of 1.2 ha paddy plot to find out the relationship between percolation rate and rice productivity. A paddy soil condition that permits percolation rate of 10-20 mm irrigation water day-1 was recommended in order to get high yield … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study on the Effect of Different Levels of Zeolit and Water Stress on Growth, Development and Essential Oil Content of Moldavian Balm (Dracocephalum moldavica L.)A. Gholizadeh, M.S.M. Amin, A.R. Anuar et al.Problem statement: In order to meet the ever increasing demand of medicinal plants, for the indigenous systems of medicine as well as for the pharmaceutical industry, some medicinal plants need to be cultivated commercially and moldavian balm (Dracocephalum moldavica) is one of them. Approach: To determine the effects of zeolite and water stress on aforementioned plant's phisiomorphological characteristics, an experiment … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,276 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
Research ArticleOpen accessIn the abstractEvaluation of Some Organic Pollutants Transport into the Shallow Groundwater and Surface Water of Jiaxing Landfill AreaSouleymane Keita, Zhonghua Tang, Shaogang Dong, Yuehua JiangProblem statement: Hangjiahu regions belong to the Yangtze River Delta region in Zhejiang Province in China. The vast majority of this region is flat, so surface and groundwater both have a low flow rate. With the rapid economic development of the area, a large number of industrial and domestic garbage are generated. These landfill or garbage are exposed and stacked. … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Delaying Sporulation by Addition of Ammonium Sulphate on the Fermentation of Palm Kernal Cake Based Substrate by Aspergillus nigerK. H. Swe, A. R. Alimon, M. RaminProblem statement: Asexual sporulation is a common reproductive mode for a diverse group of fungi and the ultimate limiting factor in fungal biomass production. Approach: Delaying sporulation may increase the biomass in terms of mycelial production and the same time increase production of enzymes. Results: In order to delay the sporulation different levels of ammonium sulphate (10, 12 and 14%) … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Constitutive Model for Multi-Line Simulation of Granular Material Behavior Using Multi-Plane PatternS. A. Sadrnejad, A. Saedi Daryan, M. ZiaeiProblem statement: Improper understanding of material behavior prevents the efficient and correct usage of available materials and consequently, increases the construction and maintenance costs and even unsuitable construction.
