Varijabilnost preživljavanja i rasta sadnica različitih klonova crne topole (Populus nigra L.) u plavnim uslovima Velikog ratnog ostrva
(Univerzitet u Beogradu, Šumarski fakultet, 2021)
Crna topola (Populus nigra L.) pripada ugriženim vrstama Srbije koje rastu na vlažnim staništima. Ovo istraživanje je sprovedeno na Velikom ratnom ostrvu, koje se nalazi na ušću reke Save u Dunav, na teritoriji grada ...
CONTRIBUTION OF DIFFERENT INTERACTIONS TO THE EXCESS GIBBS ENERGY OF MIXING IN AQUEOUS ELECTROLYTE SOLUTIONS
(Society of Physical Chemists of Serbia, 2021)
The thermodynamic properties of the mixed electrolyte solutions are conveniently described in terms of excess quantities. The excess Gibbs energy of mixing, presents the difference between the excess free energy of a mixed ...
Influence of anodization voltage on photocatalztic activity of TiO2 nanotubes
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
TiO2 under UV light generates charge carriers (electrons and holes) that take part in the process of decomposition of pollutants, which is a well-known fact for the past few decades. For this reason, TiO2 is used for ...
Preliminary results on the assessment of Danube River fish species migration behavior in relation to Iron Gate I and II dam using acoustic telemetry equipment
(Danube Delta National Institute for Research and Development, Babadag Street 165, 820112 Tulcea, Romania, 09-2021)
The dam’s construction without fish passes had a major impact, obstructing migratory fish populations from moving between different parts of the river systems and utilizing their key habitats. Fish species and fish populations ...
Assembly of tetraspanins, galectin-3, and distinct N-glycans defines the solubilization signature of seminal prostasomes from normozoospermic and oligozoospermic men
(Upsala Medical Society, 2021)
Background: Prostasomes, extracellular vesicles (EVs) abundantly present in seminal plasma, express distinct
tetraspanins (TS) and galectin-3 (gal-3), which are supposed to shape their surface by an assembly of
different ...
Narrowing of laser beam propagating through biological suspension
(Institute of Physics Belgrade, Pregrevica 118, 11080 Belgrade, Serbia, 2021)
In the experiments, the 532 nm CW laser beam is directed to the glass cuvette that is filled either with the medium or with algae suspended in the medium. We have monitored the laser beam diameter at the entrance and exit ...
MECHANICAL ENERGY HARVESTING POTENTIAL OF BiFeO3-PVDF FLEXIBLE COMPOSITES
(Faculty of Technology, University of Novi Sad, 2021)
Bismuth ferrite (BiFeO3) powders were synthesized by sol-gel methods and incorporated into flexible composites by hot pressing with polyvinylidene fluoride (α-PVDF). Several metal ions with various valances were used to ...
