The immobilization of lipase on Sepabeads: Coupling, characterization and application in geranyl butyrate synthesis in a low aqueous system
(Association of the Chemical Engineers of Serbia, 2008)
Lipase from Candida rugosa immobilized on Sepabeads EC-EP was shown to catalyze the esterification of geraniol with butyric acid in a predominantly organic system. The immobilization procedure was adjusted to optimize the ...
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 ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(University of Belgrade, Technical Faculty, Bor, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
Polymer optical fibers today / Polimerna optička vlakna danas
(Association of Chemical Engineers of Serbia, 2000)
Polymer optical fibers (so called POF) are already in wide use in a large number of fields. This paper gives an overview including a background of the development of polymer optical fibers, their advantages, various types ...
Starter cultures for semi hard cheese / Starter kulture za polutvrdi sir
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
29 starter cultures for semi hard cheese are formed from natural isolates of lactic acid bacteria. They are isolated from traditionally home made cheese produced without the addition of starter cultures. Natural isolates ...
Eksperimentalna proizvodnja fermentisanog mlečnog napitka sa probiotičkim svojstvima
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd i Poslovno udruženje za stočarstvo - grupacija za mlekarstvo, Beograd, 2002)
Kiselomlečni napici se proizvode fermentacijom laktoze dejstvom bakterija mlečne kiseline. One svojom aktivnošću povećavaju svarljivost proizvoda i sprečavaju aktivnost drugih patogenih mikroorganizama. Poboljšanje efekata ...
Rotating disk alumina precursor fiber formation process stability determination using image analysis
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Precursor fibers are made from the aluminium-hydroxide chloride based sols. The process stability can be influenced both by the fiber formation conditions and the rheology of the sol. The distance from the disk canter is ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
Effect of low-temperature plasma and chitosan treatment on wool dyeing with acid red 27
(John Wiley & Sons Inc, Hoboken, 2005)
This study examines in detail the influence of low-temperature plasma and biopolymer chitosan treatments on wool dyeability. Wool knitted fabrics were treated and characterized by whiteness and shrink-resistance measurements. ...
Nonlinear frequency response of a chromatographic column. part I: Application to estimation of adsorption isotherms with inflection points
(Taylor & Francis Inc, Philadelphia, 2005)
A new method to determine adsorption isotherms is suggested. The method is based on analysis of the nonlinear frequency response of a chromatographic column. Due to the fact that higher order frequency response functions ...
