Research ArticleOpen accessIn the abstractDelftia Acidovorans Bacteremia in an Intravenous Drug AbuserRocco J. Perla, Eric L. KnutsonDelftia acidovorans (Comamonas acidovorans) is an aerobic, non-fastidious, non-fermentative gram-negative bacillus classified in the Pseudomonas rRNA homology group III that is generally regarded as an environmental organism found in soil and water and as a non-pathogen. We report the first case of systemic D. acidovorans infection in a patient without a long-term immunosuppressive condition where D. acidovorans has been recovered … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion. VEGF has been shown to be … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,318 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model of 4-Quadrant DC Electric Drive with 6-Pulse Dual ConverterKosmas ZdrozisMathematical model simulating the operation of DC electric drive hoisting mechanism has been developed. The study illustrates the capabilities of the developed model for investigation both normal and abnormal modes of operation of the converter and the supplying voltage. Large attention was given to the thyristor converter and its firing system so that fast-proceed micro-processes occurring in the converter can … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Vibrations in Switched Reluctance Motor DrivesS. Balamurugan, R. ArumugamThis study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,826 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 abstractLaser Interaction and Related Plasma PhenomenaFrederick Osman, Peter Evans, Peter Toups et al.Computations are to be performed using the laser driven inertial fusion energy option based on volume ignition with the natural adiabatic self-similarity compression and expansion hydrodynamics [1]. The numerical work includes the establishing of a multi-branch reaction code to be used for simultaneous fusion reactions of D-D, D-T D-He3 and mutual nuclear reaction products. This will permit the studies of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Voltage Stability and Alleviation Through Knowledge Based SystemA. Arunagiri, B. VenkateshModern power systems are large sized and rapidly growing. They require constant attention to monitor their performance. Attention is also required to ensure that the voltage stability margin of the power system is above a desired level. In order to achieve the objective, this study proposes a knowledge-based system. It computes using simple Fast De-Coupled Load Flow (FDLF), the state … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,816 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.
