conclusions the study findings highlight the importance of the mental aspect of fatigue in this working group. these results have possible implications for workers’ health and well-being and for the design of shift work systems, for industrial workers. background shift work is a well-recognized occupational health hazard in both industrialized and industrially developing countries. prolonged wo...
هدف از تحقیق حاضر، بررسی تغییراتی بود که در ترجمه انگلیسی به فارسی گروه های اسمی دارای پیش توصیفات طولانی در متون پزشکی رخ می دهد. در این تحقیق سعی بر آن شد که به دو پرسش پاسخ داده شود: (الف) چه نوع تغییراتی در ترجمه انگلیسی به فارسی گروه های اسمی دارای پیش توصیفات طولانی در متون پزشکی رخ می دهد؟ و (ب) بیشترین نوع تغییر کدام میباشد؟ ازنظریه کتفورد در زمینه ی تغییرات ترجمه (translation shifts) ب...
Background: Shift work is one of the inevitable consequences of technology in which in the recent years numerous studies have been done about its effect on health. Somatic, psychological and social disturbances are among the problems that are seen more in people with shift work than other people. The current study aims to determine the prevalence of these disturbances in one of the LPG and gas ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Effect of water gas shift reaction (CO+H2O=CO2+H2) on wustite reduction has been investigated by a transient, non-isothermal mathematical model based on grain model. In this model, wustite porous pellet is reduced using Syngas, namely a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor. For this purpose, governing equations containing continuity equation of species and energy...
Approach • Complete reverse kinetics and Computational Fluid Dynamics (CFD) modeling to optimize reactor geometry for forward reactions • Measure forward kinetics in quartz & Inconel reactors to determine reactor wall catalysis • Measure forward kinetics in reactor packed with membrane material to determine catalytic activity • Measure membrane H2 permeability in presence of clean syngas compon...
Background and objective: Benzene is one of the main pollutants in air and one of the most extensive chemical compound used in both natural and industrial processes. Benzene exposure leads to the most dangerous adverse health effects, particularly blood cancer. The aim of this study was to evaluate the gas station workers’ exposure to benzene by measuring benzene in breathing air and urinary tr...
