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 ...
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 ...
Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part II. Experimental demonstration
(Elsevier, Amsterdam, 2009)
This paper demonstrates an experimental application of the nonlinear frequency response (FR) method extension to determine adsorption isotherms of binary mixtures. This method, based on the analysis of the response of a ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Elsevier Science Bv, Amsterdam, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
Supercritical carbon dioxide extraction of carrot fruit essential oil: Chemical composition and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2007)
Isolation of carrot fruit (Daucus carrota L., cultivar "Chanteney") essential oil by supercritical carbon dioxide was investigated from the pretreatment of herbaceous matrix and extraction conditions to the chemical ...
A laboratory furnace for obtaining crystals
(Int Union Crystallography, Chester, 2004)
A design for a modular device ('crystallization shelf') installed in a laboratory furnace is presented. The setup allows regulation and simultaneous crystallization tests of several substances at different temperature ...
Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods
(Elsevier Sci Ltd, Oxford, 2008)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Behavior of composite ceramics after thermal ...
Crystallization shelf
(Blackwell Publishing, Oxford, 2007)
Integration of engineered cartilage
(Elsevier Sci Ltd, Oxford, 2001)
The structure and function of cartilaginous constructs, engineered in vitro using bovine articular chondrocytes, biodegradable scaffolds and bioreactors, can be modulated by the conditions and duration of tissue cultivation. ...
