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

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

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

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
