We study the ages of a large sample (1802) of nearly face-on disk low sur-face brightness galaxies (LSBGs) using the evolutionary population synthesis (EPS)mode
The ability of Cocos nucifera L. water (CW) as non-toxic corrosion inhibitor for acid corrosion of aluminium in 0.5 mol/L HC1 has been studied using chemical te
The separation of enzymatic hydrolysis products of yeast RNA by ion-pair HPLC was studied. A modified chromatographic response function (MCRF) was proposed to a
