Research ArticleOpen accessIn the abstractCombustion Analysis of a CI Engine Performance Using Waste Cooking Biodiesel Fuel with an Artificial Neural Network AidGholamhassan NAJAFI, Barat GHOBADIAN, Talal F. YUSAF, Hadi RAHIMIA comprehensive combustion analysis has been conducted to evaluate the performance of a commercial DI engine, water cooled two cylinders, in-line, naturally aspirated, RD270 Ruggerini diesel engine using waste vegetable cooking oil as an alternative fuel. In order to compare the brake power and the torques values of the engine, it has been tested under same operating conditions with diesel … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractStabilization of Tyrosinase-Bovine Serum Albumin Crystals by GlutaraldehydeD. Norouzian, A. Akbarzadeh, M.H. Abnosi et al.Tyrosinase and bovine serum albumin were co-crystallized by saturated ammonium sulfate solution(65%) and 20% polyethylene glycol ( PEG) 6000 and n-propanol as co-solvents .The obtained crystals were cross linked by glutaraldehyde solution(1% v/v).Polyethylene glycol 6000 was found to be better co-solvent than n-propanol. The developed biocatalyst could be recycled 6 times without further loss of tyrosinase activity. No loss of … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hydroponic System for Purification of Anaerobically Treated Dairy Manure and Production of Wheat as a Nutritional Forage CropA. E. Ghaly, H.A. Farag, M. VermaA hydroponic system was developed and used for purification of an anaerobically treated dairy manure and production of forage crops. The effect of light duration, seeding rate and wastewater application rate on the crop yield and pollution potential reduction were studied. The results indicated that a wheat forage crop can be produced in 21 days from germination to harvest in … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractAd Hoc Mobile Wireless Networks Routing Protocols - A ReviewGeetha Jayakumar, G. GopinathMobile ad hoc networks(MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad-hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad-hoc network is not a new one, having been around in various forms … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 115,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vivo Anti-malarial Tests of Nigella sativa (Black Seed) Different ExtractsH.A.A. Abdulelah, B.A.H. Zainal-AbidinNigella sativa (black seed) seeds have been used as a traditional medicine for the treatment of a variety of sicknesses including parasitic diseases. Intraperitoneal and oral administrations of ethanol, chloroform and aqueous seed extracts (50, 100, 200 and 400 µL kg-1) of N. sativa, were screened in the 4-day suppressive assays for their anti-malarial properties against Plasmodium berghei in mice. … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 8,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,164 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Trivalent Aluminum and Divalent Zinc in Drinking Waters by Differential Pulse Stripping VoltammetryAhmed HassanA Sensitive and precise differential- pulse stripping voltammetric method at static mercury dropping electrode (SMDE) has been applied to measure zinc(II) by anodic stripping at pH~¼4 and aluminum(III) by adsorptive cathodic stripping mode in presence of 1&Cross10-3M N,N` -bis-2-hydroxyethyl-2-amino-ethane sulphonic acid (BES) buffer at pH~7.1 and 2⨯10-5 M of alizarin red S as a ligand in drinking water samples purchased … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characterization of Al Bond Pad Surface Treatment in Electroless Nickel Immersion Gold (ENIG) DepositionM.K. Md Arshad, A. Jalar, I. Ahmad, G. OmarThis study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment to achieve successful nickel deposition and provide reliable interconnection of under bump metallurgy in advanced packaging. During this treatment process, the aluminum pad was cleaned, activated and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Framework for Distributed Dynamic Load Balancing in Heterogeneous ClusterNeeraj Nehra, R. B. Patel, V. K. BhatDistributed Dynamic load balancing (DDLB) is an important system function destined to distribute workload among available processors to improve throughput and/or execution times of parallel computer in Cluster Computing. Instead of balancing the load in cluster by process migration, or by moving an entire process to a less loaded computer, we make an attempt to balance load by splitting processes … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 8,725 accessesView PDFCite
