propofol is a widely used anesthetic drug because of its minor complication and also its fast effect. one of most popular complication in using this drug is pain during injection that is more sever in new generation of its components (lipid-free microemulsion). other complications of propofol are bradycardia and hypotension. this study compares 3 drugs with placebo in control of these complicat...

one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...

pain in neonates can be associated with various risks and it seems essential to find a simple and acceptable method for relieving pain. pharmacologic agents are not recommended in neonates for pain relief in minor procedures but orally administered glucose solution is found to be effective. the objective of this study was to assess the efficacy of oral 30% glucose during intramuscular injection...

abstract the aim of this study was to eliminate zn deficiency and increasing yield in grapevine (vitis vinifera l) cv, askari، via trunk injection method. the experiment was carried out in the cisakht region; in randomize complete blocks design with four treatments and four replications. treatments included of zinc trunk injection in concentration 0.15, 0.3 and 0.5% amount of 500 cc was injecte...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...

laboratory and field experiments were conducted to determine the efficacy of some insecticides on the control of sarta longhorned beetle, aeolesthes sarta solsky adults and larvae. in the laboratory, three pairs of mated and non-oviposited adults were released on the logs of field elm, ulmus minor mill that had been treated with chlorpyrifos, carbaryl, permethrin or imidacloprid. in the field e...

in order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. in this field, computational tools like cfd and engine cycle simulation play a fundamental role. therefore, the goal of the present work is to simulate a high speed di diesel engine and study the combustion and major diesel engine emissions with more details,...

if an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. this mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. howeve...

background: improvement of assisted reproductive technique (art) results in higher pregnancy rates from positive beta hcg to take home baby statistics. despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. this study aimed to compare their reproductive outcomes.   methods : this pro...
