Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
Optimization of the process of calcium-carbonate dispersion stabilization for paper industry needs / Proces dobijanja stabilne disperzije kalcijum-karbonata za potrebe papirne industije
(Savez inženjera i tehničara Srbije, Beograd, 2018)
This paper presents the optimized technological process for obtaining stable calcium carbonate dispersion (CaCO3) in accordance to the standard prescribed in the paper industry. The reason for using CaCO3 in paper production ...
Effect of lactic acid fermentation on the quality of brewer's spent grain as ruminant feed / Uticaj mlečno-kiselinske fermentacije na kvalitet pivskog tropa kao hraniva za preživare
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2020)
Brewer's spent grain (BSG) was used in this study as a support for the immobilization of Lactobacillus paracasei NRRL B-4564, thus enabling the recirculation of immobilized biomass in repeated-batch fermentation. The ...
Examination of mechanical properties of acrilyc composite materials with different AL2O3 reinforcement by brazil test / Ispitivanje mehaničkih svojstava akrilatnih kompozitnih materijala sa različitim AL2O3 ojačanjima brazilskim testom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different ...
