Research ArticleOpen accessIn the abstractInfluence of Fasteners Disposition on Behaviour of Timber-Framed Walls with Double Fibre-Plaster Coating BoardsM.Kuhta, M.PremrovThis paper provides experimental analysis of timber-framed walls, coated with double fibre-plaster coating boards fastened to the timber frame. As the walls under a horizontal load actually behave like a deep composite beam, the fasteners disposition is very important and directly influences bearing capacity and stiffness of the wall. Therefore, three different groups of test samples with staple distances of … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Parameters of a Power Generating System with Shared LoadRitu Gupta, S.K. Mittal, C.M. BatraThis study presents a model, based on power generating system with shared load. The whole generating system consists of three subsystems viz: subsystem A , subsystem B and subsystem C. The subsystem A consists of one generating unit and one inbuilt transformer. The subsystem B also contains the same units and is connected in parallel to subsystem A. The output … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnomalies in a Fetus Exposed to Methotrexate in the First TrimesterLandon B. Lorenz, Eric J. KnudtsonThe increasing use of methotrexate for multiple indications in reproductive age women will likely lead to more frequent incidence of fetal exposure. Methotrexate is sometimes used for medical termination of first trimester pregnancy in combination with misoprostol. Teratogenesis in women exposed to low-dose methotrexate used for treatment of rheumatic conditions has been reported, but it has also been suggested that … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractCo-expression of Apoptosis-Related Molecules on Activated CD8+ CD38+ T-cells is Associated with HIV-1 Disease ProgressionJosé W. Rodríguez, Luis A. Rodríguez, Griselle Font et al.CD8+ T cells play a major role in controlling HIV-1 infection through the release of soluble lytic and non-lytic antiviral factors. Their decrease or defective function contributes to the HIV-1 disease progression. HIV-1 disease progression has been associated with a remarkable increase of CD38 expression on CD8+ T-cells. It has been also documented that a significant distribution of HIV-specific CD8+T-cells … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractCollapsibility and Volume Change Behavior of Unsaturated Residual SoilAzlan A. Aziz, Faisal H. Ali, chioong F. heng et al.Residual soils occur in most countries of the world but the greater areas and depths are normally found in tropical humid areas. In these places, the soil forming processes are still very active and the weathering development is much faster than the erosive factor. Most residual soil exhibit high suctions for most of the year. The absence of positive pore … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element and Experimental Serviceability Analysis of HSC Beams Strengthened with FRP SheetsSeyed Hamid Hashemi, Reza Rahgozar, Ali Akbar MaghsoudiThe use of externally bonded composite sheets or laminates is by now a diffuse technique to strengthen existing RC structures. However, some aspects of flexural condition still need experimental and numerical analysis; furthermore, especially for serviceability checks, there is a lack of code provisions. Six reinforced high strength concrete (HSC) beams strengthened with FRP sheets were fabricated and tested, the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Aorta Artery Aneurysms Using Active Electronic CircuitKamran Hassani, Mahdi Navidbakhsh, Mostafa RostamiThe fusiform and saccular aneurysms in different aorta artery sections were studied using an electronic circuit of cardiovascular system. The geometrical model of each artery section including thoracic and abdominal were generated in accordance with original anatomical data. By increasing the rate of aneurysm in each studied section, the pressure drop were calculated using CFD method, furthermore the compliance variations … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractRapamycin Inhibits Cystogenesis by Cystic Epithelial Cells Derived from Human Autosomal Dominant Polycystic KidneysGerard Elberg, Teresa V. Lewis, Lijuan Chen, Martin A. TurmanAutosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic disorders and carries a high health burden since it progresses to renal failure in half of the afflicted individuals by the 6th decade of life. Currently, there is no effective treatment to slow the progression of ADPKD. Rapamycin, a drug most commonly used as an immunosuppressive agent … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2006 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,482 accessesView PDFCite
