Kidney disease is a common complication of monoclonal immunoglobulin (MIg)-secreting B-cell disorders and predominantly occurs in patients who do not meet the criteria for an overt hematological disease. To distinguish this situation from monoclonal gammopathy of undetermined significance, which lacks organ damage, the term monoclonal gammopathy of renal significance (MGRS) was introduced to depict the association of a small, otherwise indolent B-cell clone, with renal disease induced by the secreted MIg. The spectrum of renal disorders in MGRS is wide, encompassing both tubular and glomerular disorders, classified according to the composition of deposits and their ultrastructural pattern of organization.

Millions of tons of zinc plant leach residues (ZPLR) have been stockpiled in Iranian hydrometallurgical zinc plants during the last few decades. Due to the low grades of zinc, lead, and silver in these residues, these residues have been abandoned without treatment. The authors of this paper studied zinc plant leach residues (ZPLR) to propose a flotation process for separating and producing lead and silver concentrate.

Chalcopyrite has evolved into a crucial source of copper pollution, and xanthates inevitably coexisted with chalcopyrite in mine environments. However, the effect of xanthate on chalcopyrite bio-dissolution has not been illustrated yet. To fill this knowledge gap, the effect of potassium amyl xanthate (KAX) on copper release from chalcopyrite mediated by Acidithiobacillus ferrooxidans was investigated.

Relative rate studies of the gas-phase reaction of amyl methacrylate, CH═C(CH)C(O)O[CH]CH, with OH radicals were performed at (298 ± 2) K and 1000 mbar. The experiments were conducted in an atmospheric Pyrex chamber coupled to Fourier transform infrared spectroscopy (FTIR). The rate coefficient obtained from the average of several experiments was = (8.
