Operating regime of a biphasic oil/aqueous hollow-fibre reactor with immobilized lipase for oil hydrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Lipase from Candida rugosa was immobilized on Cuprophane membrane in a hollow-fibre module for possible application for oil hydrolysis. A simple immobilization technique was applied and 154.8 mg m(-2) lipase was immobilized ...
Possibilities of recycling of magnesium and magnesium alloys
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper are presented results of experimental investigation of processing of non oil-contaminated metal scrap based on magnesium and its alloys. These are the firs investigations of magnesium scrap recycling in Serbia ...
Optical fibers with composite magnetic coating for magnetic field sensing
(Elsevier Science Bv, Amsterdam, 2004)
The investigated system for optical fiber sensor was multi-mode optical fiber with magnetic composite coating. Polymer component of composite coating was poly (ethylene-co-vinyl acetate)-EVA, and the magnetic component was ...

Reversible addition fragmentation chain transfer polymerization - RAFT / Radikalna polimerizacija sa ravnotežnim adiciono-fragmentacionim prenosom lančane aktivnosti - RAFT
(Association of Chemical Engineers of Serbia, 2004)
The fundamentals of controlled radical polymerization are presented in this review. The paper focuses on reversible addition fragmentation chain transfer (RAFT) polymerization. The mechanism and specifics of this type of ...
Characterization and antimicrobial activity of bacteriocin 217 produced by natural isolate Lactobacillus paracasei subsp paracasei BGBUK2-16
(Int Assoc Food Protection, Des Moines, 2004)
The strain Lactobacillus paracasei subsp. paracasei BGBUK2-16, which was isolated from traditionally homemade white-pickled cheese, produces bacteriocin 217 (Bac217; similar to7 kDa). The onset of Bac217 biosynthesis was ...
Viscoelastic properties of Na-alginate solution
(Association of Chemical Engineers of Serbia, 2004)
The evolution of oscillatory-induced structure of Na-alginate solutions was studied for various frequencies and concentrations. The specific rate of elastic modulus increase, as well as the specific rate of loss modulus ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...
