Research ArticleOpen accessIn the abstractEffect of Covers and Rainfall on Soil and Water Conservation Using a Tilting Flume ModelS. Compliew, L. Suwanchai, N. KrongwiengThe effect of stone and vegetative covers was evaluated for soil and water conservation in a waterway on salty soils in the Northeast of Thailand. Experiments were conducted on a hydraulic tilting flume under simulated unit flow (120 and 45 cm2s-1), rainfall (120 mm/hr) and slope (0, 1.2,1.4,1.6,1.8,2.0, 2.2, 2.4, 2.6, 2.8 and 3.0%) conditions. The depth of soil was … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Vitamin C on the Metabolic Parameters of Experimental Diabetes MellitusMariam Al-Shamsi, Amr Amin, Ernest AdeghateThe role of vitamin C on diabetes mellitus is unknown. The purpose of this study was to examine the effect of oral administration of vitamin C on some of the metabolic parameters of diabetic rats. Diabetes was induced by intraperitoneal injection of STZ (60 mg kgˉ1 body weight at 12 weeks of age). Vitamin C (10, 50, 100 mg kgˉ1 … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 1 · 31 Mar 2007 · 8,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiamond Pressing on the Wear Resistance and the State of Heat Treated Alloy Steel SurfacesUbeidulla Al-QawabehaIn manufacturing processes, surfaces and their properties are as important as the bulk properties of the materials. Surface treatment is an important aspect of all manufacturing processes. It has been used to impart certain physical and mechanical properties, such as appearance, corrosion, friction, wear and fatigue resistance. Widely used methods of finishing treatment that create necessary parts with the given … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,099 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 abstractLow Complexity Performance Effective Task Scheduling Algorithm for Heterogeneous Computing EnvironmentsE. Ilavarasan, P. ThambiduraiA heterogeneous computing environment is a suite of heterogeneous processors interconnected by high-speed networks, thereby promising high speed processing of computationally intensive applications with diverse computing needs. Scheduling of an application modeled by Directed Acyclic Graph (DAG) is a key issue when aiming at high performance in this kind of environment. The problem is generally addressed in terms of task … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 9,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in Erucic Acid Concentration of Rape Seeds in Advanced GenerationsSelim Aytaç, Şahin Gizlenci, Mustafa Acar, Ali ÜstünThis study was carried out to determine the extend of changes in erucic acid concentration of rapeseeds which were grown in Carsamba and Bafra Plains of Central Blacksea Region. In addition to field experiments, the same experiment was conducted in the greenhouse to avoid polen transfer from other sources. The first material used was 00 type rapeseed cultivars. In order … …OnLine Journal of Biological Sciences, Vol. 6, Issue 2 · 31 Dec 2006 · 6,626 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunological Evidence for Peptide-Carbohydrate Mimicry with a Group A Streptococcus Polysaccharide-Mimetic PeptideSilvia Borrelli, Rehana B. Hossany, Susan Findlay, B. Mario PintoThe immunogenicity of a peptide-protein conjugate developed by linking a peptide mimic DRPVPY of the Group A Streptococcus cell-wall polysaccharide (GAS-CWPS), to tetanus toxoid (TT) was examined. BALB/c mice were immunized three times subcutaneously following homologous or heterologous prime/boost strategies at 4- or 6- week intervals in two different experiments. DRPVPY-TT, CWPS-TT, heat-killed, pepsin-treated GAS bacteria (with exposed polysaccharide) and … …American Journal of Immunology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractPathophysiology of Adipocyte Defects and Dyslipidemia in HIV Lipodystrophy: New Evidence from Metabolic and Molecular StudiesAshok Balasubramanyam, Rajagopal V. Sekhar, Farook Jahoor et al.Despite a burgeoning mass of descriptive information regarding the epidemiology, clinical features, body composition changes, hormonal alterations and dyslipidemic patterns in patients with HIV lipodystrophy syndrome (HLS), the specific biochemical pathways that are dysregulated in the condition and the molecular mechanisms that lead to their dysfunction, remain relatively unexplored. In this paper, we review studies that detail the metabolic basis … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,608 accessesView PDFCite
