Partial dealcoholization of red wine by nanofiltration and its effect on anthocyanin and resveratrol levels
(SAGE Publications Inc., 2016)
The present work studies the use of nanofiltration for the production of red wine concentrate with low alcohol content. Factorial design was applied to measure the influences of transmembrane pressure (10-20 bar) and ...
Determination of pKa values of some butyrophenones, their sensitive LC-UV analysis in pharmaceutical dosage forms and stress degradation behavior under ICH-recommended stress conditions
(2013)
In this study, pKa values of some ionizable butyrophenones, namely, benperidol, droperidol, and haloperidol were determined using by the dependence of the retention factor on pH of the mobile phase. The effect of the mobile ...
Arbitrarily long factorizations in mapping class groups
(Oxford University Press, 2015)
Abstract. On a compact oriented surface of genus g with n ≥ 1 boundary components, δ1, δ2, . . . , δn, we consider positive factorizations of the boundary multitwist tδ1 tδ2 · · ·tδn , where tδi is the positive Dehn twist ...
