Research ArticleOpen accessIn the abstractReduced Order Models of a Current Source Inverter Induction Motor DriveIbrahim K. Al-AbbasProblem Statement: The current source inverter induction motor (CSI-IM) drive was widely used in various industries. The main disadvantage of this drive was nonlinearity and complexity. This work was done to develop a simple drive systems models. Approach: The MATLAB/SIMULINK software was used for system modeling. Three reduced models were developed by choosing specific frame, neglecting stator transients and ignoring … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,865 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPopulation Growth, Climate Change and Water Scarcity in the Southwestern United StatesAmy c. Fuller, Michael O. HarhayProblem statement: In a simple economic model, water scarcity arises as a result of an imbalance between the supply of and demand for water sources. Distribution in this setting is the source of numerous conflicts globally. Approach: Already, the Southwestern United States (US) suffers from annual drought and long-standing feud over natural water resources. Results: Population growth in the Southwestern … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 10,042 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAccumulation and Effect of Manganese on Chloroplasts and Antioxidant Responses in Arabidopsis ThalianaJun Xing, Xue Yang, Cailing YuanIn this study, 5-day-old seedlings of Arabidopsis thaliana were exposed to 0, 0.5, and 1.0 mmol/L MnCl₂ for 6 days by using three independent biological replicates. The results indicated that Mn content in roots exhibited a dose-dependent increase with rising external Mn supply. The elevated Mn levels led to significant reductions in the nutrient content of K, Ca, Na, and … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 18 Jul 2026 · 824 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAntioxidant and Photosynthetic Responses in Plants Under Boron Toxicity: A ReviewLucia Guidi, Alberto Pardossi, Elena Degl’Innocenti, Marco LandiBoron (B) is a micronutrient that has long been known essential not only for plants and animals. Otherwise, in crop plants the range of B concentration from essentiality to toxicity appears extremely narrow. Although B deficiency has been well investigated, during recent years many researchers have also investigated boron toxicity effects, making progress in the comprehension of boron transport within … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Jul 2012 · 12,762 accessesView PDF Cite
