Introduction: Nuclear radiation is potentially harmful to humans and soil contamination with radionuclides is the main source of human radiation exposure. These radionuclides can., enter to human body through the food chain. In this study, 34 soil samples were collected from between Arak city and Shazand Power Plant over 20 km length and analyzed. Materials and Methods: The specific activities ...

nezam-abad area is located in southwest of shazand (arak) which is a part of sanandaj-sirjan zone. major intrusive rocks of nezam-abad are quartz diorite and minor amount of granodiorite. leucogranitic, pegmatite dykes and quartz-tourmaline veins were intruded the quartz diorite. quartz diorites are mainly composed of plagioclase, hornblende, biotite, quartz and pyroxene as major minerals. majo...

Background: One of the main sources of exposure to radiation is terrestrial radionuclides in the environment. These radioisotopes are present in the Earthchr('39')s crust and can be increased by human activity such as mining of coal, oil, and minerals. Materials and Methods: In this study, 39 soil samples including virgin and cultivated were collected from around of the Shazand Refinery Complex...

Industrial process control system due to integration of equipment, existing material and energy recycle streams and their effects are extraordinary importance. The process in terms of safety, product quality and control stability have a challenge when there was defects in a process control system. The isomerization process is gaining importance in the presence of refining context due to upgradi...

conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...

The aim of this research was to investigate the effect of index species, Astragalusammodendron on the associated plants of Agropyron tauri and Bromus tomentellus fromdifferent aspects in Shazand rangeland in southwest of Markazi province. The effects ofspecies density and distribution pattern and then index species on the soil properties werestudied. Based on the randomized – systematic method,...
