dead yeast cells are an abundant residue of the brazilian ethanol industry and the industries still don’t have a proper or desirable destiny for all these cells, which means tons of vitamins and proteins that have not a major end. in the other hand, heavy metal residues are a problem, especially for leather industry, where brazil is also a great producer. in this work, dead yeast cells were us...
One of the pollutants produced by gas and petrochemical industries in Assaluyeh region is heavy metals which, by entering of these industries into the Persian Gulf, has caused water and aquatic pollution. Therefore, in the present study were investigated the concentration of non-carcinogenic hazard quotient index (NHQI) of heavy metals (Fe, Cr, Pb, Cu, Zn, Cd, Se, Ni) in Persian Gulf waters and...
One of the main concerns of all industries such as mine industries is to increase their profit and keep their customers through improving quality level of their products; but increasing the quality of products usually releases air pollutants. Nowadays the management of air pollutant emissions with harmful environmental and health effects is one of the most pressing problems. In this paper, auth...
Today, the growth of population, the excessive growth of cities and subsequently, the industries development in all parts of the planet are evident. Such development leads to the entrance of chemical martials with various compounds, particularly heavy metals, in aquatic ecosystems. In this study, the contamination of the sediments around the Mighan wetland basin with heavy metals such as lead, ...

Combustion of solid particles from the two aspects of "safety of industries related metal particles" and "optimization of combustion in solid fuels engines " is important. At this article the effect of strain rate on the counterflow premixed flame of aluminum particles is studied. Energy equations for counterflow combustion of metal particles derived and analytically solved. Curve of flame...
