conclusions these results revealed that cirrhosis produce prolonged qt interval and sour cherry extract has an ameliorating effect on qt prolongation probably via its antiarrhythmic property. results results were analyzed by using student t-test and one-way anova. p < 0.05 was considered as significant level. the qt interval was calculated using the bazettʼs formula and corrected qt (qtc) was o...

abstract shortage and improper distribution of rainfall in tea growing period are important growth limiting factors in tea fields in northern part of iran. if there is not any other limited factors, supplemental irrigation by sprinkler can increase tea yield. this study was carried out in order to investigate the optimum sprinkler irrigation interval on yield and water use efficiency of tea. th...

background: the aim of this study was to investigate the effects of high-intensity interval training (hiit) on nitric oxide metabolites (no2 - , no3 - ) and myocardial infarct size after ischemia/reperfusion (i/r) injury in healthy male rats. methods: a total of 44 wistar rats were randomly divided into 4 groups including hiit (n=8), hiit + ir protocol (n=14), control (n=8), and control + ir (n...

data envelopment analysis (dea) is a non-parametric technique for evaluation of relative efficiency of decision making units described by multiple inputs and outputs. it is based on solving linear programming problems. since 1978 when basic dea model was introduced many its modifications were formulated. among them are two or multi-stage models with serial or parallel structure often called net...

intelligent wells provide the ability for monitoring and control of downhole environment of the wells. downhole monitoring is achieved through sensors while control is realized with downhole valves. recovery from intelligent wells can be improved by proper selection of candidate wells/fields and optimizing the number, location and performance of the installed interval control valves. design cri...
