Background and purpose: The purpose of this study was to compare ultrasound and urine analysis and shock index with CT scan in the diagnosis of intraabdominal injury (IAI) in blunt abdominal trauma (BAT). Material and Methods: During 2011/3/21 to 2012/3/20, all adult patients with BAT presenting to the Emergency Department of Imam Hossain Hospital were studied. The sensitivity, specificity, po...
In this paper, we empirically investigate the relationship between oil price changes and output in a group of oil exporting countries. The dynamics of business cycles in Libya, Saudi Arabia, Nigeria, Kuwait, Venezuela and Qatar are modeled by alternative regime switching models. We show that the extension of uni-variate Markov Switching model in order to include oil revenue improves dating busi...
Introduction:This study examined the effects of administration of subcutaneous β-estradiol on PTSD-like symptoms (the enhanced conditioned fear response, CFR) that induced by a single-prolonged stress (SPS) and shock in rats. Adult male Wistar rats were exposed to SPS procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. Then the rats were placed in fear conditioning syste...
In recent years, some research has focused on the importance of the origin of an oil shock for macroeconomic dynamics in both oil-exporting and importing countries. The existing literature lacks a proper open Stochastic Dynamic General Equilibrium (DSGE) framework to investigate the effect of the origins of oil shocks on macro variables in a two-country model consisting of an oil-exporting coun...
Protecting armored vehicles from mine explosion can lead to the survival of thousands of people exposed to this risk. Very purpose, shock absorbers such as honeycomb structures can be applied for crashworthiness improvement. In this study, graded honeycomb structure is primarily introduced as a shock absorber, followed by the introduction of its absorbed energy and the force and acceleration ap...
In this article, the stress-time or speed-time relation for a steady intense shock wave front and effective parameters on it in solid metals (except alkaline metals) were studied. First, the parameters relevant to the deformation of a pure material were identified and a relation between them was found. Then with simplifying assumptions, a stress change equation was obtained. Afterwards, the mod...
This study investigated the asymmetric effects of financial instability shocks on economic growth and monetary policy shocks on financial instability in Iran. For this purpose,data 1991:3 to 2017:1 and nonlinear auto-regressive distributed lag (NARDL) approach has been used. For this purpose, three models have been estimated. In the first model, the asymmetric effects of fiscal instability shoc...
Sepsis is the systemic response to severe infection in critically ill patients. Sepsis, septic syndrome & septic shock represent the increasingly severe stages of the same disease. Despite the remarkable improvements in outcome, sepsis & septic shock remain an important cause of morbidity & mortality in children. This is a retrospective study among the patients who were admitted in the pediatri...
This study examines the effects of demographic changes including decreasing fertility and increasing life expectancy and retirement age on the financial sustainability of the pension fund in Iran using the overlapping generation model and the Stochastic Dynamic General Equilibrium (DSGE) approach. The results of simulation and evaluation of impulse response functions and evaluation of correlati...
