Introduction: Industrial accident is one of the most minatory elements for worker’s health, productivity and organizational performance. Unsafe behavior is the main reason associated with occurrence of accidents. The main goal of this study was application of participatory techniques to achieve control measures of these behaviors. .Material and Method: Using safety behavior sampling techn...

Background and Objectives: Few investigations on polycyclic aromatic hydrocarbons (PAHs) in surface sediments have reported medium to high petrogenic contamination at the southwest coasts of the Caspian Sea. The aim of this study was to investigate distribution and potential sources of 16 PAH compounds in surface sediments of the southwest coasts of the Caspian Sea (Gillan province). Materials ...

  Analysis of the Characteristics of Sultry Days in Iran   Extended Abstract Sultry phenomenon occurs due to the combined effect of high temperature and humidity. Sultry intensity increases with increasing relative humidity and decreases with decreasing temperature. This phenomenon has a tremendous impact on comfort and other human activities. Various indices have been used to study this ph...

Stage – discharge relationship is mainly developed from measured data in any hydrometry station. Measured data usually obtain in low to medium flow discharge, because in most cases it is very difficult to measure the flow discharge during flood. Therefore, the stage–discharge is extrapolated beyond the measured data to compute the flood which may estimate low or higher value. This is because du...
