The main aim of the study was to prepare GSE by solvent – solvent extraction method, identifying various phytochemical compounds present in the extract, examining

SEPARATION OF ZINC FROM MANGANESE BY SOLVENT EXTRACTION FROM ACIDIC LEACHATES OF SPENT ZINC-MnO 2 DRY CELLS USING NEUTRAL ORGANOPHOSPHORUS EXTRACTANTS.. Vinício Francisco Ibiapina a

Here, we consider a general regenerative process that includes Smith’s model and show that it is important to consider finite time quantities instead of asymptotic ones and

The sewage treatment station achieved a significant efficiency index in the elimination of fecal coliforms, and in the rainy period there was a reduction of 99.8% and

The methods under study differed mainly in the mass of the sample, solvent, time, and temperature used for the extraction of γ -oryzanol and the separation of impurities

Network simulation module 157 The first steps consist in determine the efficiency value computed by EPANET for each variable- speed pump in all periods of time (considering
