Ekstrakcija estrogenih hormona iz vode korišćenjem ugljeničnog kriogela kao sorbenta
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2021)
Za ekstrakciju estrogenih hormona (estrona, 17β-estradiola i 17α-etinilestradiola) iz vodenih rastvora metodom ekstrakcije na čvrstoj fazi, u ovom radu korišćen je ugljenični kriogel kao sorbent. Metoda ekstrakcije na ...
Application of unmalted raw materials in brewing
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2021)
The huge popularity of beer arises from its pleasant sensory attributes and favorable nutritional
characteristics as well as its lower cost, compared to other types of alcoholic beverages. The most important raw materials ...
SiO2 and TiO2 -Hybrid Material for Removal of As(V) and Pb(II) Ions from Aqueous Solution
(Serbian Chemical Society, 2021)
The aim of this research was to investigate As(V) and Pb(II) adsorption behaviour onto mineral heterostructures based on the mixture of Si and Ti-oxides (MHO). Heavy metals are discharged into water bodies from various ...
Phoenix spectra for determination of the fundamental stellar parameters
(Institute of Physics, Belgrade, SerbiaAstronomical Observatory Belgrade, Serbia, 2021)
We present a set of calculated spectra for stellar atmospheres. Temperature is
varied from 2500-10000K, log g from 0.5 to 5.5, z from 0.5 to 2.5 and alpha
enhancement -0.2 to +0.8. Our aim is to use these spectra as ...
Synthesis and biological evaluation of some azo dyes based on 3-cyano-6-hydroxy-4-methyl-1-propyl-2-pyridone / Sinteza i biološka svojstva nekih azo boja na bazi 3-cijano-6-hidroksi-4-metil-1-propil-2-piridona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2021)
Azo dyes are the most important group of organic synthetic dyes. High molar extinction coefficients, which characterize azo compounds, contribute to their wide use in traditional dyeing of various materials, as well as the ...
Kardiovaskularni lekovi u rečnoj vodi Beograda
(Akademija tehničkih strukovnih studija Beograd, 2021)
Glavni put dospevanja lekova u životnu sredinu su komunalne otpadne vode. U regionu
Beograda, otpadne vode se direktno ispuštaju u reke Savu i Dunav, što negativno utiče na kvalitet
rečne vode. Zbog svoje postojanosti i ...
