background and purpose: two important clinical education methods are problem-based and student-centered. however, education of “clinical decision-making skills” and “application of clinical knowledge” is important. usually training these cases is done in small groups . in this study, new method of scientific textbooks with four factors mentioned above has been implemented in large education gro...

extract: physical mobility and exercise are necessary for people health. for patient with mobility limitation this issue has more importance because these exercises help them to return to normal function more effectively. since the individual planning for each patient is not time effective, so we could plan group exercises and perform properly in orthopedic wards. the important goals of this pl...

background: the effects of estrogene on central nervous system are still controversial. objective: we aimed to investigate the effects of raloxifene on the antioxidant enzyme [superoxide dismutase (sod) and catalase (cat)] activities and malondialdehyde (mda) levels in brain homogenates of ovariectomized female rats and its effect on cognitive process of learning. materials and methods: female ...

objective: to evaluate the efficacy and side effects of oxybutinin in comparison to tolterodine in treatment of overactive bladder (oab) with detrussor overactivity (doa) in iranian women. materials and methods: one hundred iranian old women with clinical symptoms of oab who show ido in the filling cystometry participated in this randomized double-blinded parallel-group by using two kinds of th...

background: according to recent studies comparing magnetic resonance enterography (mre) with ileocolonoscopy for assessing inflammation of small bowel and colonic segments in adults with active crohn’s disease (cd), we aimed to compare the accuracy of these two diagnostic methods in iranian population. method: during 2013-2014 a follow-up study was done on 30 patients with active cd ina gastroe...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

background: failure in reaching the predetermined goals of education can be considered as one of the most important problems of educational systems. today, it is believed that active teaching methods are more effective than lecturing which lead to effective teaching. participation of students in education is one of the major factors of active learning. the purpose of the present study is to det...

surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...

active carbons were produced from bagasse, millet and sorghum straws by chemical activation with h3po4. carbon precursors with particle size of 1180 î¼m were used, in order to overcome difficulties caused by low density and high ash content. the influence of preparation conditions (temperature, residence time, and acid impregnation ratio) on the yield of the active carbons was examined. the imp...

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...
