Research ArticleOpen accessIn the abstractExtracts of Pumpkin (Cucurbita pepo L.) Seeds Suppress Stimulated Peripheral Blood Mononuclear Cells in vitroChristiana Winkler, Barbara Wirleitner, Katharaina Schroecksnadel et al.In the traditional medicine in North America and Mexico, pumpkin seeds have been used as an anthelmintic agent and for supportive treatment in functional disorders of the bladder. Also anti-inflammatory and cardioprotective activity of pumpkin seeds is discussed. Three different extracts of pumpkin seeds were prepared and effects were investigated in unstimulated human peripheral blood mononuclear cells and in cells … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 10,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotovoltaic Technology of Electricity Generation for Desert CampingShafiqur Rehman, Ali A. Shash, Omar S. Baghabra Al-AmoudiThis study presents a case study on the utilization of global solar radiation data on horizontal surface to perform economical feasibility of using Photovoltaic (PV) panels with battery backup to meet a small load for a camping site in Saudi Arabia. The analysis considers three scenarios with daily average energy demands of: (i) full load, (ii) 75% load and (iii) … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractVegetation Dynamics in the Tafileh Woodlands of Southern JordanSaleh Al-Qura'nWoodland vegetation in the Tafileh highlands of southern Jordan was investigated and quantitatively surveyed to determine the patterns of vegetation dynamics associated with altitude and topography. Three tree species (Juniperus phoenicea L. (evergreen needle-leaved woodland resistant to cold), Pistacia atlantica Desf. and Quercus aegilps L. (cold-deciduos broad-leaved woodland) and five shrubs (Colutea istria Miller, Gomphocarpus sinaicus R. Br., Thymelaea hirsute … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganizations and Activities of a New Leading Farmer Extension Model in TurkeyGürel AydinWith this study, the organization and the activities of four leading farmer association established in Thrace Region of Turkey in 1986, in the center of Tekirdag and in Muratli, Corlu and Malkara districts of Tekirdag, were discussed as the result of the common studies between Turkish Agricultural Chamber Union (TZOB) and German agriculture unit (Deutsche Landwirtschafts-Gesellschaft, DLG), German Agricultural Technical … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractBy-pass Devices as Effective Means of Protection from the Hydraulic HammerKhalid S. Al-RababaSwitching-off the parallel working pump units causes sudden discharge changes in parallel pipe lines, as a result of that hydraulic shocks takes place. The damping of these shocks can be achieved by the installation of the by-pass devices between the parallel lines of the piping system. The analytical calculations demonstrate that the reduction in hydraulic shocks reaches 40% and considerable … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of the Output and Employment Conversion Matrices of Australia's EconomyAbbas Valadkhani, Tim RobinsonBased on two snapshots taken from the Australian economy, this study quantifies the impacts of final demand aggregates on output and employment in various sectors using the 1989 and 1997 conversion matrices. The sectoral output and employment are linked with final demand deliveries in such a way that one can measure the impacts on changes in each component of aggregate … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal Time Hybrid Controller Implementation for Switched Reluctance Motor DriveS. Paramasivam, R. ArumugamThis study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under soft chopping operation. The … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractCivil Liberties and Computer MonitoringKevin Curran, Steven McIntyre, Hugo Meenan et al.Civil Liberties-the term used for the fundamental liberties and rights of a country's citizen is the right of free speech, thought and action. This is the fundamental building block of a democratic society. This research essay outlines the current measures western governments are taking to ensure our safety and the associated costs of civil and human rights. …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,956 accessesView PDFCite
