Sulfur (S) is an essential mineral for animals and serves many important biological functions in the animal’s body. However, when excess S is present in ruminant diets, neurological problems can occur. When feed and water containing high levels of S (greater than 0.40% of diet DM) are fed to ruminants, a condition called polioencephalomalacia (PEM) can occur. Polioencephalomalcia is caused by n...

This paper presents the new geochemical isotopes Sr and Nd, and the mineralization data for the south Neyshabour volcanic rocks located in NE Iran. Based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. All the analyzed volcanic rocks display enrichment in light rare earth elements (LREE) relative to th...

Sulphur can be present in mineral insulating oil and manifest stable, highly reactive corrosive form. The sulphur reacts with the copper conductor transformer forms semi conductive sulphide at surface of conductor. paper insulation used on may get damaged due to sulfide deposits which also affect partial discharge activities prevalent paper-oil insulation. model is studied online measurement Di...

kalchoye copper-gold deposit is located about 110 kilometers east of esfahan province and within the eocene volcano sedimentary rocks. sandy tuff and andesite lava are important members of this complex.the form of mineralization in area is vein and veinlet and quartz as the main gangue phase. the main ore minerals are chalcopyrite, chalcocite, galena and weathered minerals such as goethite, iro...
