Isopiestic investigation of the osmotic and activity coefficients of {yMgCl(2)+(1-y)MgSO4}(aq) and the osmotic coefficients of Na2SO4 center dot MgSO4(aq) at 298.15 K
(Springer/Plenum Publishers, New York, 2008)
Isopiestic vapor-pressure measurements were made for {yMgCl(2) + (1-y)MgSO4}(aq) solutions with MgCl2 ionic strength fractions of y = (0,0.1997,0.3989,0.5992,0.8008, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Fermentation processes by immobilized cell systems in beverage production
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
Immobilized cell technology has been investigated and used in various bio-industries as well as in processes based on alcoholic fermentation, like beer, wine and cider fermentation processes. Some of the most important ...
Densities and excess molar volumes of the ternary mixture 2-butanol plus chloroform plus benzene and binary mixtures 2-butanol plus chloroform, or plus benzene over the temperature range (288.15 to 313.15) K
(Amer Chemical Soc, Washington, 2008)
Densities rho and excess molar volumes V(E) of the 2-butanol + chloroform + benzene ternary mixtures and two binaries, 2-butanol + chloroform and 2-butanol + benzene, have been determined. Experimental rho measurements ...
Corrosion stability of epoxy coatings on aluminum pretreated by vinyltriethoxysilane
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The electrochemical and transport properties and adhesion of epoxy coatings electrodeposited on aluminum pretreated by vinyltriethoxysilane (VTES) were investigated during exposure to 3% NaCl. The VTES films were deposited ...
Assessment of viscoelastic crack bridging toughening in refractory materials
(Elsevier Sci Ltd, Oxford, 2008)
Viscoelastic bridges can be formed in refractory ceramics while cooling from high temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress intensity factors leading to higher resistance ...
The optimization of zinc dialkyldithiocarbamates synthesis and determination of their antioxidant activity
(Association of the Chemical Engineers of Serbia, 2008)
A two-step optimized laboratory synthetic method of zinc dialkyldithiocarbamates is presented. In the course of the first phase, a sodium salt of dialkyldithiocarbamic acid has been synthesized from the dialkylamines, ...
Influence of chain length and degree of branching of alcohol plus chlorobenzene mixtures on determination and modelling of V-E by CEOS and CEOS/G(E) mixing rules
(Elsevier Science Bv, Amsterdam, 2008)
The densities of binary mixtures of (1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol+chlorobenzene) have been measured at temperatures 288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K and atmospheric pressure while ...
Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
Kinetics and specificity of Lipozyme-catalysed oil hydrolysis in supercritical CO(2)
(Inst Chemical Engineers, Rugby, 2008)
Blackcurrant seed oil is rich in linoleic and linolenic acids. Selective enzyme-catalysed oil hydrolysis was studied with aim to obtain different levels of alpha- and/or gamma-linolenic acid in the mixture of liberated ...
Characterization of Intestinal Isolates of Lactic Acid Bacteria with Potential Probiotic Ability from Premature Born Nursling
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
Five samples of feces from premature born nursling were taken from Institute of Neonatology (Belgrade). Three different media based on MRS was used for isolation of intestinal isolates of lactic acid bacteria. From 25 ...
