Immobilization of yeast cells in PVA particles for beer fermentation
(Elsevier Sci Ltd, Oxford, 2007)
In this study, the potential of application of non-aggressive LentiKat (R) technique for brewer's yeast immobilization on polyvinyl alcohol was assessed. High cell loads of about 109 cells/ml were achieved by this procedure ...
Determination of the protective properties of electrodeposited organic epoxy coatings on aluminium and modified aluminium surfaces
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces (anodized, phosphatized and chromatized-phosphatized aluminium) have been ...
Spray drying of Gentiana asclepiadea L. root extract: Successful encapsulation into powders with preserved stability of bioactive compounds
(Industrial Crops and Products, 2021)
Willow gentian as a source of bitter compounds is traditionally used for digestive disorders. Gentiana root extract was spray dried using five different carriers (maltodextrin, whey protein, pectin, starch, gelatine) at ...
Osmotic and activity coefficients of {yNa(2)So(4)+ (1-y)ZnSO4}(aq) T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2005)
The osmotic coefficients of the mixed electrolyte solution {y Na2SO4 + (1 - y)ZnSO4} (aq) have been measured by the isopiestic method, at T = 298.5 K. The experimental results were treated by Scatchard's, Pitzer-Kim's and ...
Nonlinear properties and stability of SnO2 varistors prepared by evaporation and decomposition of suspensions
(Elsevier Sci Ltd, Oxford, 2005)
SnO2 varistors doped with CoO, Cr2O3 and Nb2O5 were prepared by evaporation and decomposition of suspensions. The composition of the varistors was optimized to improve electrical properties, such as nonlinearity, leakage ...
Prediction of the Lee retention indices of polycyclic aromatic hydrocarbons by artificial neural network
(Elsevier, Amsterdam, 2006)
A quantitative structure retention relationship technique using an artificial neural network (ANN) has been used for the prediction of the Lee retention indices for PAHs on SE-52 and DB-5 stationary phases. The selected ...
Estimation of single solute adsorption isotherms applying the nonlinear frequency response method using non-optimal frequencies
(Elsevier, Amsterdam, 2008)
In order to estimate single solute adsorption isotherms, the nonlinear frequency response (FR) of a chromatographic column is analyzed experimentally and evaluated using the concept of higher order frequency response ...
A novel approach to determination of carbonyl groups in DMAc/LiCl-insoluble pulps by fluorescence labeling
(Springer, Dordrecht, 2006)
The CCOA method for profiling of carbonyl groups by fluorescence labeling has meanwhile become an established procedure for dissolving pulps and rag papers. High molecular weight pulps, such as certain paper pulps, could ...
Effect of temperature on the excess molar volumes of some alcohol plus aromatic mixtures and modelling by cubic EOS mixing rules
(Elsevier, 2006)
Densities of the (methanol + benzene), (ethanol + benzene), (methanol + chlorobenzene) and (ethanol + chlorobenzene) mixtures have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K) and ...
Characterization of microflora in homemade semi-hard white Zlatar cheese
(Elsevier Science Bv, Amsterdam, 2007)
The Zlatar cheese belongs to the group of traditionally homemade cheeses, which are produced from nonpasteurized cow's milk, without adding of any bacterial starter culture. Changes were followed in lactic acid bacteria ...
