(Društvo ekonomista Beograda, Beograd, 2013)
Uneven regional development in Serbian economy is the one of the most complex problems of its economic development. Even the regional development problems were in the past too, but it is now very important and very actual ...
Uniaxial tension of drying sieves / Jednoosno zatezanje sušnih sita
(Association of Chemical Engineers of Serbia, 2013)
Although the literature contains numerous studies that have been developed to describe the nonlinear behavior of drying sieves operation, there are no papers that report deeper investigation of the drying sieve behavior ...
Correlation of liquid-liquid equilibria of non-ideal binary systems using the non-random, two-liquid model / Korelisanje ravnoteže tečno-tečno neidealnih binarnih sistema pomoću NRTL modela
(Serbian Chemical Society, Belgrade, 2013)
The non-random, two-liquid (NRTL) model with three different forms of temperature dependant parameters was used to correlate the liquidliquid equilibrium data for systems of alcohols with alkanes, and alcohols with two ...
Prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomials / Predskazivanje termofizičkih i transportnih svojstava trojnih organskih neelektrolitnih sistema, uključujući vodu, pomoću polinoma
(Serbian Chemical Society, Belgrade, 2013)
The description and prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomial equations are reviewed. Empirical equations of Radojković et al. (also known ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...

The thermal degradation of some polymeric di-alkyl esters of itaconic acid / Termička razgradnja nekih polimernih dialkil estara itakonske kiseline
(Serbian Chemical Society, Belgrade, 2013)
One group of polymers that may help relieve the dependence on crude oil is based on itaconic acid, the biotechnological production of which has become feasible. Itaconic acid and its derivatives can easily be incurporated ...
Asymmetric hydrogel membranes for heavy metal adsorption
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we ...
Asymmetric polyethersulfone membranes with crosslinked poly(glycidyl methacrylate) particles
(Belgrade : Serbian Chemical Society, 2013)
Polyethersulfone (PES) is frequently used for high-performance ultrafiltration membranes. Functionalization of PES membranes is required to introduce new groups for specific applications, such as affinity membranes for ...
