Partitioning of cellulolytic activity in the polyethylene glycol/dextran two-phase systems / Raspodela celulolitičke aktivnosti u dvofaznim sistemima polietilenglikol/dekstran
(Faculty of Technology, Novi Sad, 2012)
This study is concerned with the partitioning of cellulolytic activity in the polyethylene glycol/dextran two-phase systems. In the system of 10% (w/w) polyethylene glycol 1500/5% (w/w) dextran 500,000/80% (w/w) crude ...
Intellectual property related to traditional and modern agriculture in Serbia / Intelektualna svojina u tradicionalnoj i modernoj poljoprivredi Srbije
(Naučno društvo agrarnih ekonomista Balkana, Beograd; Institut za ekonomiku poljoprivrede, Beograd i Akademija ekonomskih nauka, Bukurešt, 2012)
Agricultural progress has been the most important factor which leads to humans' civilization. The world has progressed in such a rapid manner that traditional agriculture has aggressively been replaced by modern agricultural ...
Cavitation resistance of composite polyester resin/basalt powder
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The paper presents the results of research on cavitation resistance of the composite based on unsaturated polyester resin and basalt powder, as reinforcement. Basalt powder was obtained by grinding and micronising basaltic ...

(Institute of Pesticides and Environmental Protection, 2013)
In the present work, the efficiencies of three different sample preparation methods for GC/ MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum spelta) samples fermented by Lactobacillus ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Preparation of glass-ceramic in Li2O-Al2O3-GeO2-P2O5 system
(University of Novi Sad, 2013)
The results of preparation and structural characterization of glass-ceramics from the system Li2O-Al2O3-GeO2-P2O5 are shown in this paper. The crystallization behaviour of the selected glass was examined under non-isothermal ...
Intellectual property and regulation of functional foods
(Economics institute, Belgrade, 2012)
Today, there exist scientific evidences that functional foods have favorable physiological and psychological effects as well as additional functions in relation to health, apart from the basic nutritional effects, thus ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
Assessment of the integrity of welded pipes / Procena integriteta zavarenih cevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The subject of the paper is analysis of the integrity of welded pipes made of API J55 steel by high frequency contact welding (HF). Experimental research on the mechanical properties of the base material was conducted on ...
Treatment of waste sulfuric acid copper electrolyte / Tretman otpadnog sumporno-kiselog elektrolita bakra
