single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. when an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. these methods either reduce the voltage of the st...

case presentation the studied patient was a 32-year-old g1p1 woman with abdominal pain who was diagnosed with a large ovarian cyst during ovulation induction, which could possibly raise the risk of ovarian torsion. she had a 2-year secondary infertility and had received three cycles of ovulation induction with letrozole 6 months earlier. an emergency laparoscopy showed large complex ovarian cys...

dna polymerase gene from thermus aquaticus strain yt1 was amplified using venttm dna po-lymerase and cloned under the control of x.pr promoter and expression was induced by a shift in tern perature. the culture was then sonicated, and after centrifugation the lysate was treated with poly ethyleneimine followed by a salting-out step. finally the protein was precipitated with ammonium sulfate and...

background: the aim of the present study was to induce salivation in haemaphysalis longicornis to increase saliva production and to characterize the collection of proteins present in the collected saliva using on-chip-electrophoresis. methods: saliva of adult female engorged h. longicornis was collected by treatment with 0.2% dopamine hydrochlo­ride. all protein samples were characterized by sd...

objective: in this study efficacy of sub lingual misoprostol was examined in comparison to oxytocin (i.v.) for inducing of labor in term pregnancy. materials and methods: seventy patients were allocated by blocked randomization to groups a (n=35, sub lingual misoprostol 25 μg four hourly to maximum of 5 doses) and b (n=35, continuous oxytocin infusion). results: delivery active phase and total ...

background: clomiphen citrate (cc) is the first line therapy for women with infertility and poly cystic ovary syndrome( pcos). however, 20-25% of women are resistant to cc and do not ovulate. objective: the objective of this study was to evaluate the efficacy of sequential treatment of metformin and incremental doses of letrozole in induction of ovulation in cases of cc-resistant pcos patients....

the purpose of this study is to show the effect of extraamniotic administration of corticosteroids to shorten the times to either active labor and/or delivery. this is a double blind randomized study. 65 patients who were candidates for the termination of pregnancy between the ages of 16-45, with intact membranes and unripe cervix were randomly divided into two groups, a study group (n=34) and ...
