Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...

objective: to compare efficacy, safety and tolerance of combination of mifepristone and misoprostol versus misoprostol-only in induction of late intrauterine fetal death (iufd). materials and methods: this prospective study included a consecutive series of 52 women gravid up to fourth with iufd after 28 weeks of gestation between january 2008 and june 2011. women were divided into two groups. f...

objective: the aim of this study was to evaluate and compare the population of natural killer t lymphocyte (nkt) in the uterus and spleen of the hyperstimulated and control mice at the seventh day of pregnancy. materials and methods: the superovulated and control mice were put individually in a cage with a male mouse. in the next morning they were considered for observing the vaginal plag. the...

aim and background: the behavioral inhibition system (bis) and the behavioral activation system (bas) are considered as factors to verify the effects of personality significance on cortical activity. the present study explored the effects of the bis and bas on frontal asymmetry in response to affect stimuli. methods and materials: this study included 36 individuals (18 with high bas sensitivity...

background: the purpose of this study was to compare the three different strategies, intravenous (iv) hydroxylethyl starch (hes), iv human albumin (ha), and oral cabergoline (cb) in the prevention of ovarian hyperstimulation syndrome (ohss). materials and methods: in this prospective randomized clinical trial, 91 women at high risk of developing ohss were allocated into the three groups, group ...

background: chitin is an abundant natural polysaccharide found in fungi, algae, and exoskeleton of insects. several bacterial species are capable of utilizing chitin as their carbon source. these bacteria produce chitinases for degradation of chitin into n-acetyl-d-glucosamine. so far, regulation of the chitinase encoding genes has been studied in different bacterial species. among bacillus spe...

voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. this phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. in this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...

background: the retrieval of good quality oocytes that is accomplished with selection of the best induction ovulation protocol on the basis of patients condition, age and cause of infertility, is one of the most important aspects of art cycles. the objective was to evaluate the efficacy of low dose, long acting gnrh-a (decapeptyle) for pituitary desensitization and outcome of art compared to lo...
