Određivanje veštačkog zaslađivača saharina u uzorcima otpadne vode / Determination of artificial sweetener saccharin in wastewater samples
(Beograd : Beogradska politehnika, 2019)
Široka primena veštačkih zaslađivača u prehrambenoj i farmaceutskoj industriji počela je početkom osamdesetih godina prošlog veka. Većina ovih jedinjenja se ne metaboliše u ljudskom telu i izlučuje se uglavnom nepromenjena. ...
Effect of Polyhedral Oligo Silsesquioxanes (Poss) Particles on Cavitation Resistance of Hybrid Composite Films
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2019)
The objective of this study is to investigate the influence of the polyhedral oligo silsesquioxanes (POSS) structure on cavitation erosion of hybrid acrylate composite films. Cavitation is used as a method for estimation ...

Distribution of saturated hydrocarbons in unweathered and erosional landforms
(Lodz University of Technology, 2019)
Badlands are worldwide erosional landforms. The
formation of different badland morphologies is due to
the type of sedimentary bedrock, especially texture
and cementation degree, as well as climate.
In this study badlandes ...
