introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...

As a pre-treatment method of refractory gold ore, carbonaceous matter (C-matter) flotation was investigated with multi-stage by rougher, scavenger, and cleaner stages. Different dosages kerosene MIBC (4-Methyl-2-pentanol) were applied the optimum dosage selected testing in each stage. With combination stage, four circuit designs suggested, which single-stage rougher (R), rougher-scavenger (R+S)...

Scavenger receptors act as membrane-bound and soluble proteins that bind to macromolecular complexes and pathogens. This diverse supergroup of proteins mediates binding to modified lipoprotein particles which regulate the initiation and progression of atherosclerotic plaques. In vascular tissues, scavenger receptors are implicated in regulating intracellular signaling, lipid accumulation, foam ...
