this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...
introduction: assessing quality of life for patients with shoulder instability may be essential because of the negative impacts of the disease on patient’s life. the aim of the present study, therefore, was to assess the internal validity and consistency, test-retest reliability, and convergent validity of the persian version of the oxford shoulder instability score (osis). material ...
the resistant* of patesa against lateral displacement (le. the stability), was studied tinder a range of conditions in vitro, at a range of knee flexion angles. muscle forces were applied in physiological directions along the separate quadriceps muscles. normal muscle actions with constant tension showed constant patellar stability up to sixty degrees knee flexion, and then a significant increa...
in this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. the pipe is considered as a timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the winkler-model and the shear constant of the pasternak-model. the external flow force, acting on the beam in the direction of the flexural displacement is...
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...
Divorce and separation demolish family as a basic unit of a society. This research aim was the survey of Confidence and Intimacy in Predicting of Marital Instability. This is a descriptive-correlation research. 90 male and 90 female were randomly selected. The Instruments were Walker Intimacy Scale, Confidence Scale and Marital Instability Questionnaires. Pearson Correlation method and step by ...
Regarding to the importance of the relationship between macroeconomic instability and exchange rate pass-through, present study by using EGARCH and smooth transition regression (STR) model has examined the nonlinear effect of macroeconomic instability on the exchange rate pass-through of Iran during the period 1963-2010. For this, firstly the macroeconomic instability index has been estimated u...
Introduction: Ankle sprain is one of the most common injuries among the athletes. According to some research, balance deficit and ankle instability are reported in those with chronic ankle instability. The aim of this study was studying the effect of 6 weeks' new balance training in the land and water on balance, instability index and pain in the athletes with chronic ankle instability. Metho...
The main objective of this study is to evaluate the impact of maritime transportation instability on international trade instability based on wavelet smoothing and spatial panel data econometric method during the period 1990-2012. The results showed that the spatial effects have an impact on international trade instability. So that a sudden 100 percent increase in international trade in the nei...
conclusion significant functional performance deficits were observed in the fai group in all tests except single hop test with greater deficits observed in the fai-gw group. hence, these tests can be used to determine the presence of fai. however no deficits were identified for the test involving sagittal plane functional activities suggesting that this test can not be used as a criterion to di...
