Background: post operative pain is an essential problem. Epidural infusion of two different doses of bupivacaine in pain management of post orthopedic surgeries was studied. Methods: In this double blinded randomized clinical trial we studied two groups of 42 patients undergone knee surgery. Based on block randomization, patients received two different concentration of bupivacaine (0.1% or 0.1...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
This study investigates whether the emotional effects of music can be manipulated by social influence in an online music listening setting. More than 5000 participants listened to five randomly chosen music excerpts (of a total of 23 excerpts) and, after each one, rated induced emotions along arousal and valence dimensions. By providing different labels for the same information about the emotio...
L2 written corrective feedback has been investigated from different perspectives in SLA research (e.g. Ahmadian & Tajabadi, 2015; Bitchener & Knoch, 2010; Ferris, 2006). Taking the cognitive and sociocultural paradigms into account, the aims of the current study are twofold: Firstly, it attempts to find if corrective feedback is effective in improving the linguistic accuracy of L2 learners' ten...
BACKGROUND The effect of aminophylline on maximum respiratory muscle strength in patients undergoing upper abdominal surgery was investigated. METHODS An open pilot study was performed in which aminophylline was administered continuously for 48 hours after surgery (protocol I). In a second group of subjects aminophylline was given for 24 hours after cholecystectomy in a double blind placebo c...
myocardial injury was induced in 25 dogs by infusing isoprenaline, 2-4 microgram per kg per minute for the duration of six hours. 10 dogs served as controls which received only physiological saline. animals receiving isoprenaline 2 microgram per kg per minute were labelled as experimental group a and other receiving microgram per kg per minute as experimental group b. histopathological observat...
Background and Objectives: Previous studies have indicated that lithium may increase the level of the brain-derived neurotrophic factor (BDNF), which in turn improves the recovery of patients with stroke. In this controlled trial we evaluated the effect of lithium on BDNF serum level in patients with ischemic stroke. Methods: In this randomized controlled...
Responsible gambling tools (e.g., limit-setting tools, pop-up messages, and personalized feedback) have become increasingly popular as a way of facilitating players to gamble in a more responsible manner. However, relatively few studies have evaluated whether such tools actually work. The present study examined whether the use of three types of information (i.e., personalized feedback, normativ...
We study the stability of voluntary cooperation in response to varying group growth rates. Using a laboratory public-good game, we construct a situation where increasing group size yields potential efficiency gains, but only with sustained cooperation. We then study the effect of exogenously varying growth rates on cooperation. Slow growth yields higher cooperation rates and welfare than fast g...
