An alternative route for valorization of valuable metals from jarosite residue / Alternativna metoda za valorizaciju vrednih metala iz jarosit ostatka
(Savez inženjera i tehničara Srbije, Beograd, 2019)
This paper aims to consider the treatment of jarosite residue using a different reducing agents, aluminum, magnesium, and carbon. The jarosite residue is not standard-it contains higher amounts of Pb and Ag, as well as in, ...
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 ...
Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Nedestruktivno praćenje stanja građevinskih objekata se bazira na merenju vibracija objekata pri dinamičkim ispitivanjima ili u toku njihove eksploatacije. U ovu svrhu se sve više koriste mreže bežičnih senzora koje čine ...
Simulation of blast furnace operation during the substitution of coke and pulverized coal with granulated waste plastic / Simulacija rada visoke peći prilikom supstitucije koksa i sprašenog uglja granulisanom otpadnom plastikom
(Savez inženjera i tehničara Srbije, Beograd, 2014)
The possibility of using the waste plastic as reducing agent in blast furnace for obtaining pig iron is in focus for the past couple year. The simulation of blast furnace process in BFC software has been performed in order ...
Fluorescence analysis of liposomal membranes permeability / Fluorimetrijska analiza permeabilnosti lipozomalnih membrana
(Savez inženjera i tehničara Srbije, Beograd, 2019)
The present study provides insight into changes in the liposomal membrane fluidity as a result of variation of structural components (two types of standard phospholipids - 1,2-dipalmitoyl-sn-glycerero3-phosphocholine, i.e. ...
