Water reservoir systems have important role to control the surface water and provide various demands, such as irrigation, domestic, industrial and hydroelectric power generation. Therefore, it is necessary to study the behavior of these systems to provide demand satisfactorily. Assessment the reservoir system behavior during the drought periods is very important. Water release, always is less then the demand during the drought period. This study, assess the performance of within-year and over-year reservoir systems under different values of vulnerability index. Sustainability index was used to obtain the optimal performance of reservoir systems. Reservoir system was simulated using modified SPA method. Assessment of reservoir performance under different values of vulnerability index in sites showed that the sustainability for within-year system is generally maximum at 25% vulnerability and for over-year system is maximum at 35%-40% vulnerability.

Background and objectives: Carpal Tunnel Syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. Conventional electro diagnosis studies have been useful in the diagnosis of this condition. The Terminal Latency Index (TLI) is a derived neurophysiological value that adjusts the Distal motor Latency (DL) for the terminal distance and motor nerve Conduction Velocity (CV).Several studies have suggested utility of the median TLI for diagnosis of CTS.The goal of this study is to evaluate prospectively the sensitivity of the median TLI in the diagnosis of CTS and compare it with other electrodiagnosis techniques.Material and Methods: This study was done on 111 patients as CTS group & 62 healthy subject as control group. In all groups five selected tests of electrodiagnosis were done and all of them were compared with TLI sensitivity.Results: The mean TLI was 0.3±0.05 in the CTS group and 0.42±0.03 in the control group. The sensitivity of TLI was 73% The TLI wasn't statistically better than the other tests, but in three cases from the CTS group, the TLI was the only abnormal test.The 7 and 14 cm method had meaningful sensitivity in contrary to other tests.Conclusion: The sensitivity of TLI has no meaningful difference with other routine electro diagnostic tests in diagnosis of CTS.The median TLI is a useful but not more sensitive electrodiagnostic test for CTS.

Introduction: Three methods of OCRA Index, Strain Index (SI), and ACGIH HAL have been proposed for the assessment of risk factors of upper limb musculoskeletal disorders. Investigating the correlation and consistency of these three methods are of prominence importance in the workplaces. Thus, this study aimed to determine the correlations of the results of the above mentioned methods. Materials and Methods: In this cross-sectional study, a total of 150 tasks were studied in four industries. For each task, a video taping of a full working cycle was prepared and evaluated according to the instructions of each method. The level of risk exposure to musculoskeletal disorders was analyzed with correlation and Kappa agreement coefficient tests using SPSS (version 16) and R software packages.Results: The correlation between the results of risk assessments of OCRA and SI methods for right and left hands were acceptable and equal to 0.751 and 0.726, respectively (p<0.001). Meanwhile, the coefficients of agreement between OCRA and HAL methods for left and right hands were 0.526 and 0.595, respectively.Conclusion: These findings partly confirmed the agreement between the methods of risk assessment. The origin of this partial agreement can be the number and type of variables and their impacts on the final score of the methods.

Background- Coronary artery bypass grafting (CABG) is a common surgical procedure performed in the world. Coronary artery disease (CAD) has become prevalent in Iran, and the aim of this study is to assess the effects of CABG on LV systolic and diastolic function indices. We also attempted to disclose the CABG effect on the myocardial performance (Tei) index.Methods- 50 patients were enrolled in this study, all of whom were given instructions about the research program. They were admitted to our center electively for CABG; the first echocardiography was taken just prior to surgery, and the second TTE was performed between 1 and 43 weeks after surgery (mean=11 weeks).Results- CABG had dramatic effects on the patients, as their mean left ventricular ejection fraction (LVEF) rose from 48.88% to 52.54% (P<0.001). It was more obvious in patients with preoperative LVEF less than 40%, Tei index<0.49, male gender and those with complete revascularization. LVEF had no change in the case of incomplete revascularization. MPI (Tei) decreased significantly after CABG from 0.4992 to 0.4462 (P=0.001), which was more pronounced in those whose preoperative Tei index was equal or more than 0.49 and in patients with triple vessel or left main CAD. Diastolic function recovery had a time-dependent manner with no change or even deterioration during the first few days after CABG, but after 4 weeks nearly half of the patients had normal diastolic function. History of systemic hypertension and old age (>60 years old) are both associated with more preoperative diastolic dysfunction and are negative predictors for diastolic function recovery after CABG. Isovolumetric relaxation time (IVRT), E-wave deceleration time (EDT), peak E-wave velocity (PEV) and peak A-wave velocity (PA) all show significant improvement after CABG. There was no mortality in our series.Conclusion- CABG has important positive and significant effects on many LV systolic and diastolic indices including LVEF, LVESV, IVRT, PEV, PAY and EDT as well as on the myocardial performance (Tei) index.

Introduction: J.E.Hirsch introduced H Index to scientometric domain, representing actual scientific profitability quality of a researcher’s publications; and is equal to effective index for researchers. Literature review: Studies showed that documents database have provided different H scores for each researcher and for different scientific fields. Despite the utmost advantages of H-index it also have some flaws such as need to use complementary indices such as m, r, g index. Conclusions: The strength point of H index, is its ability to use in limited levels which is an complementary for other bibliomeetric exist indexes. This Index, with others, could be a suit index to improvement scientific levels for researchers, scientist, and scientific board members.
