Effects of pH and sugar concentration in Zygosaccharomyces rouxii growth and time for spoilage in concentrated grape juice at isothermal and non-isothermal conditions
(Elsevier, 2013-09)
The effect of pH (1.7–3.2) and sugar concentration (64–68 °Brix) on the growth of Zygosaccharomyces rouxii MC9 using response surface methodology was studied. Experiments were carried out in concentrated grape juice ...
Concentration of EPA and DHA from refined salmon oil by optimizing the urea-fatty acid adduction reaction conditions using response surface methodology
(MDPI AG, 2019)
This research focused on obtaining eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) (EPA+DHA) concentrates from refined commercial salmon oil (RCSO). Independent variables of the complexation ...
Effect of dexmedetomidine on the minimum alveolar concentration of isoflurane in cats
(2012-04-01)
This study reports the effects of dexmedetomidine on the minimum alveolar concentration of isoflurane (MAC iso) in cats. Six healthy adult female cats were used. MAC iso and dexmedetomidine pharmacokinetics had previously ...
Toward pH-controllable bioelectrocatalysis for hydrogen peroxide based on polymer brushes
(2013-04-01)
In the present work, a biosensor was built with smart material based on polymer brushes. The biosensor demonstrated a pH-sensitive on-off property, and it was further used to control or modulate the electrochemical responses ...
Optimization of a synbiotic formulation of soy yoghurt containing yacon extract by response surface methodology
(2010-12-01)
A synbiotic yoghurt based on a combination of soymilk and yacon water extract (from yacon root tubers) was developed as a novel food product fermented with a probiotic culture of Enterococcus faecium CRL 183 and Lactobacillus ...
Optimization of temperature, sugar concentration, and inoculum size to maximize ethanol production without significant decrease in yeast cell viability
(Springer, 2009-06-01)
Aiming to obtain rapid fermentations with high ethanol yields and a retention of high final viabilities (responses), a 2(3) full-factorial central composite design combined with response surface methodology was employed ...
Plasma concentrations of progesterone, 17 beta-estradiol and androstenedione and superovulatory response of nelore cows (Bos indicus) treated with FSH
(Butterworth-heinemann, 1996-03-01)
Progesterone (P-4), 17 beta- estradiol (E2) and androstenedione (A4) plasma concentrations were correlated with palpated corpora lutea (CL), recovered embryos and viable embryos in 13 Nelore cows induced to superovulate ...
Pentraxin-3 concentration in the amniotic fluid of women at term, in spontaneous preterm labor and when not in labor
(Elsevier B.V., 2014-05-01)
Objective: To evaluate the concentration of PTX3 in amniotic fluid (AF) during the final weeks of normal pregnancies and in pregnancies complicated by preterm delivery (PTD).Study design: A cross-sectional study was conducted ...
