Research ArticleOpen accessEvery word in the titleSimulation of Airflow and Aerodynamic Forces Acting on a Rotating Turbine VentilatorA.S. Farahani, N.M. Adam, M.K.A. AriffinProblem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,719 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleComputation of a Single-phase Shell-Type Transformer Windings Forces Caused by Inrush and Short-circuit CurrentsM. B.B. Sharifian, R. Esmaeilzadeh, M. Farrokhifar et al.This research studies the forces on the windings of transformer due to inrush current. These forces are compared with the corresponding forces due to short-circuit of the windings. Two-dimensional finite element computation of a single-phase shell-type transformer is carried out based on the maximum permissible inrush current value where its amplitude is the same as the rated short-circuit current. To … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 7,437 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Evolution Force of Genome Reduction in Carnivorous PlantsMing-Yue Ma, Tao Tan, Xin-Xin Yin et al.The introns are widely present in the genome of eukaryotes and the distribution of intron varies greatly among different organisms or different genes. Generally, introns loss is an important way for uneven distribution of intron during genome evolution. In this study, two closely related carnivorous plants (Genlisea aurea and Utricularia gibba) were chosen, their genome were relatively integrity and high … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 26 May 2018 · 10,348 accessesView PDF Cite
