Swelling kinetics and impregnation of PLA with thymol under supercritical CO2 conditions / Kinetika bubrenja PLA i njegova impregnacija timolom upotrebom natkritičnog uglenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The present work was aimed to study swelling kinetics of polylactic acid (PLA) and its impregnation with thymol in supercritical carbon dioxide (scCO2) medium. The influences of temperature and soaking time on the swelling ...
Simultaneous crystallization testing in a crucible furnace
(University of Kragujevac, Faculty of Science, 2012)
An air-cooled test tube, with a series of modular and movable rings (cylindrical-multilateral, folding-matryoshka 'crystallization comb-key'), installed in a laboratory crucible furnace is presented. The setup allows easy ...
Air pollutant emission forecasting in Belgrade using artificial neural networks / Predviđanje emisija odabranih zagađujućih materija vazduha u Beogradu korišćenjem veštačkih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2013)
Intensive industrial development has led to the increase of pollutants in the air, water and land. In order to gain a clear insight into the sources of emissions, many countries have implemented registers of pollutants in ...
Analysis of copper losses throughout weak acid effluent flows generated during off-gas treatment in the new copper smelter RTB Bor
(Association of Metallurgical Engineers of Serbia, 2013)
The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter ...
Gelatin as a carrier system for delivery of polyphenols compounds / Želatin kao nosač za isporuku polifenolnih komponenata
(Savez inženjera i tehničara Srbije, Beograd, 2017)
In the present study, the influence of different encapsulation techniques (lyophilization and spray drying) on gelatin, as a carrier system for delivery of polyphenols compounds, on wild thyme extracts and on encapsulated ...
Ultrasound as a physical treatment of stillage for lactic acid fermentation / Ultrazvuk kao fizički tretman za pripremu džibre za mlečno-kiselinsku fermentaciju
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2016)
In this study, the stillage from the bioethanol production on wasted bread has been used as a substrate for fermentation by lactic acid bacteria. Ultrasound has been studied as a physical treatment of wasted bread stillage ...
Lactic acid production on brewers' spent grain hydrolysate by lactobacillus Rhamnosus and Lactobacillus fermentum / Mlečno-kisela fermentacija hidrolizata pivskog tropa pomoću lactobacillus Rhamnosus i Lactobacillus fermentum
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2014)
Brewers' spent grain (BSG) is the major by-product of the brewing industry, representing around 85% of the total by-products generated. Per 100 L of beer produced 20 kg of brewer's spent grain are obtained. BSG is a ...
Competitive sorption of silver, zinc and copper ions on different types of sorbent / Komparativna sorpcija jona teških metala na različitim tipovima sorbenata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
In this master thesis the sorption of heavy metals on activated carbon and zeolite was analyzed. The chosen heavy metals (Ag+, Cu2+, Zn2+) have been analyzed separately and as a mixture in order to check their sorption ...
Dioxins in soil: Sources of pollution and distribution / Dioksini u zemljištu - izvori zagađenja i raspodela
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2013)
The term dioxins is commonly used to refer to group of polychlorinated organic compounds, that includes 75 congeners of dibenzo-p-dioxins (PCDDs) and 135 congeners of dibenzo-furans (PCDFs). They are classified as the most ...
The application of the zeolyte powder for the construction of the dense composite membranes for the carbon-dioxide separation / Primena zeolitnih prahova za izradu kompozitnih polimernih membrana za separaciju ugljen-dioksida
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
