in this study, modeling and optimization of coagulation and flocculation processes in cod removal of galvanized wastewater treatment plant of mobarakeh steel complex (msc) were studied. experiments of this study were designed using response surface method which is one of the most efficient methods in experimental design. the variables assessed in this study, are four factors including ph, input...

BACKGROUND & OBJECTIVES Rodents belonging to Gerbillinae subfamily are the main reservoir hosts of zoonotic cutaneous leishmaniasis (ZCL) in Iran. Regarding the important role of these rodents in the maintenance of Leishmania major in the nature, their identification with morphometric, cytogenetic and molecular methods seems to be essential. The karyotype study of these species, captured from a...

  A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...

Obtaining temperature distribution data of slabs under rolling is essential as the mechanical and metallurgical properties of the metal under this process vary with temperature. Using the control volume method, a mathematical model is employed in this study to predict slab temperature in the hot roll process at Mobarakeh Steel Company. The effects of different parameters including the heat resu...

Water is the key of national development. Wherever a spring has been dried out or a river has changed its course, the area’s people have migrated and have been scattered and the area’s civilization has lost its brilliance. Today, air pollution, global warming and ozone layer damage are as the problems of countries, but certainly in the next decade the shortage and pollution of waters will be im...
