Introduction: Although noise characteristics such as intensity and frequency are the main cause of detrimental effects, it is important to pay attention to the personality traits of individuals as the host of adverse health effects. The aim of this study was to investigate the effect of personality traits on sensitivity, annoyance and loudness perception due to exposure to high frequency sound....
An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...
introduction: ultrasonography is currently being used as one of the diagnostic modalities in various medical emergencies for screening of trauma patients. the diagnostic value of this modality in detection of traumatic chest injuries has been evaluated by several studies but its diagnostic accuracy in diagnosis of pulmonary contusion is a matter of discussion. therefore, the present study aimed...
The known ore deposits and mineralization trends are important key exploration criteria in mineral exploration within a specific region. Fry analysis has conventionally been considered as a suitable method to determine the mineralization trends related to linear structures. Based upon literature sources, to date, no investigation has been carried out that includes the Sensitivity Analysis of Fe...

Analysis of economic losses from natural hazards assumes greater importance as societies expand, while extreme natural phenomena become more variable. The economic impact, of electricity outages resulting from an earthquake, has been simulated using a CGE model. The economic region is Memphis, Tennessee, which suffered the most powerful earthquake ever recorded in the US. Several sets of policy...
تجارب دانش آموزان دبیرستانی در مورد پیش بینی کننده های مصرف دخانیات : یک تحلیل محتوی کیفی نظریه محور
Background and Objectives: Tobacco use is one of the most important risk factors that increases the burden of diseases worldwide. Based on the increasing speed of tobacco use, the aim of the present study was to explain the experiences of high school students about the determiners of use and non-use of tobacco (cigarettes and hookah) based on the theory of protection motivation. Materials an...
background: the present study aims to evaluate the cost-effectiveness of dynamic interspinous spacer (coflex®) and static spacer (x-stop ®) compared to laminectomy (lami) in patients with lumbar spinal stenosis. methods: a decision-analysis model was developed to estimate the cost-effectiveness. the effectiveness parameters were obtained from a systematic literature review in relevant databas...
