(Serbian Chemical Society, Belgrade, 2009)
Solvent effects on the reactivity of cycloalkenecarboxylic, cycloalkeneacetic, 2-substituted cyclohex-1-enecarboxylic, 2-substituted benzoic, 2-substituted cyclohex-1-eneacetic, 2-substituted phenylacetic, 2-phenylcycloh ...
The Influence of Brewer’s Yeast Autolysate and Lactic Acid Bacteria on the Production of a Functional Food Additive Based on Beetroot Juice Fermentation
(University of Zagreb, 2004)
The importance of »functional foods« in the world is increasing, and the procedures for their production are under intense development. The goal of this paper is to optimise the production of a functional food additive ...
Modeling of the substrate and product transfer coefficients for ethanol fermentation
(WILEY-VCH Verlag GmbH & Co., 2008)
The transfer phenomena of the substrate and product for ethanol fermentation with immobilized biocatalyst were investigated. Fermentation was carried out with a biocatalyst consisting of Ca-alginate gel in the form of ...
Numerical modeling of ductile fracture initiation in structural steel / Numeričko modelisanje inicijalizacije daktilne frakture u strukturnom čeliku
(University of Niš, 2001)
Numerical modeling of ductile fracture initiation on a precracked geometry, taking into account the behaviour of simple uncracked material, has been done in the scope of micromechanical analysis. Numerical simulation has ...
Antifreeze life cycle assessment: II. Mathematical modelling / Životni ciklus antifriza: II. Rezultati matematičkog modelovanja
(Association of Chemical Engineers of Serbia, 2005)
A mathematical model based on the mass and energy balances of all the processes included in antifreeze life cycle assesment (LCA) was defined in the first part of this study [1]. The part of energy that can be transformed ...

(Savez inženjera i tehničara tekstilaca Srbije, 2002)
Razmatrane su neke metode i uređaji za ispitivanje ponašanja tekstilnih materijala pri jednostrukom i višestrukom dejstvu spoljašnjih aksijalnih sila čiji je intenzitet manji od prekidnog. U radu su prikazani različiti ...
INVESTIGATION OF DIELECTRIC PROPERTIES AND ELECTRIC RESISTANCE OF SOME TEXTILE MATERIALS
(Belgrade : Serbian Physical Society, 2003)
It is well known that textile materials are mostly dielectrics. Dielectric properties of textile materials condition the phenomenon of static electricity during their contact with other objects. This often has a negative ...
