abstract despite sophisticated conventional medical treatment and the continued development and improvement of coronary revascularization modalities in recent years, a significant number of patients still suffer from refractory angina pectoris and cannot be successfully managed. advances in therapeutic options have led to an increase in the average of life expectancy even in such no-option pati...

background: cryopreservation and in vitro maturation (ivm) of oocyte is becoming an important technique in infertility treatment and fertility preservation. also it has been proposed to establish a genetic resource bank for endangered or commercially important animal species. objective: the aim of this study was to evaluate viability, maturation and fertilization rate of mouse immature oocytes ...

the aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel moldpowders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samplescontaining such compositions as mno, fe2o3, li2o, tio2 and zno, as well as another fluorine-free samplecontaining a combination of fe2o3 and tio2, were prepared in this research...

arginine (arg) requirements of male broilers (ross 308) reared at high altitude (2100 mabove sea level) during the 1-to 3-week period was estimated in a graded supplementationmethod, in which six diets (230 g kg-1 cp and 3200 kcal me kg-1) with arg increments of1.25 g kg-1 were applied to four pens of fifteen birds each. dietary arg content of theexperimental groups ranged from 10 g kg-1 (80% o...

this paper presents a new strategy based on multi-stage fuzzy (msf) pid controller based on artificial bee colony (abc) for damping power system stabilizer (pss) in multi-machine environment. the recent studies in artificial intelligence demonstrated that the abc optimization is strong intelligent method in complicated stability problems. also, finding the parameters of pid controller in power ...
