Ekogenotoksikološka procena kvaliteta površinskih voda komet testom na različitim tkivima klena (Squalius cephalus L.) / Ecogenotoxicological evaluation of surface water quality with comet assay on different tissues of european chub (Squalius cephalus L.)
(Univerzitet u Beogradu, Biološki fakultet, 2016)
Intenzivni procesi proizvodnje i oslobađanje velikog broja hemijskih agenasa, kao i metala u spoljašnju sredinu, najvećim delom u rečne tokove, dovela je do potrebe za primenom testova koji će detektovati njihov genotoksični ...
Uticaj rastvora amonijum-nitrata i natrijum-sulfata na mehanička svojstva i strukturu geopolimera na bazi elektrofilterskog pepela termoelektrana / Effects of ammonium nitrate and sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
Geopolimeri na bazi tri različita uzorka elektrofilterskog pepela izloženi su dejstvu koncentrovanog rastvora NH4NO3 (480 g/dm3) i rastvora Na2SO4 (50 g/dm3) u periodu od 18 meseci. Promene mehaničkih svojstava geopolimera ...
Magnetna i električna svojstva keramičkih kompozitnih materijala na bazi nikl-cink-ferita i barijum-titanata dobijenih postupkom auto-sagorevanja / Magnetic and electric properties of ceramic composite materials based on nikel-zinc ferrite and barium titanate obtained by the auto-combustion route
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2017)
U ovoj doktorskoj disertaciji ispitivana su magneto-električna svojstva kompozitnih materijala koji se sastoje od magnetne faze, nikl-cink ferita, i feroelektrične faze, barijum titanata u razlicitim masenim odnosima. ...
Actinobacteria may influence white truffle (Tuber magnatum Pico) nutrition, ascocarp degradation and interactions with other soil fungi
(Elsevier Sci Ltd, Oxford, 2013)
To test the hypothesis that truffle-associated bacteria may improve truffle nutrition, we isolated bacteria from white truffle ascocarps and tested Actinobacteria for their ability to solubilise phosphate and iron, nutrients ...
Use of Chenopodium murale L. transgenic hairy root in vitro culture system as a new tool for allelopathic assays
(Elsevier Gmbh, Munich, 2012)
We investigated Chenopodium murale transgenic hairy root in vitro culture system as a new tool for allelopathic assays. Transgenic hairy roots were induced by Agrobacterium rhizogenes A4M70GUS from roots, cotyledons, leaves, ...
Kinetics of the hydrogen evolution reaction on Ni-(Ebonex-supported Ru) composite coatings in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The hydrogen evolution reaction (HER) was studied on Ni, Ni-Ebonex and Ni-(Ebonex-Ru) coatings in 1 mol dm(-3) NaOH solution at 25 degrees C. The composite coatings were electro-deposited from a nickel Watts-type bath ...
Effects of mixed saline and alkaline stress on the morphology and anatomy of pisum sativum l.: the role of peroxidase and ascorbate oxidase in growth regulation
(Srpsko biološko društvo, Beograd, i dr., 2013)
The effects of hyperalkaline, thermo-mineral water from Slatina on the morphology and anatomy of pea plants (Pisum sativum L.), were examined after eleven days of treatment with a mixture of tap water and Slatina water in ...
Linking oxidative and salinity stress tolerance in barley: can root antioxidant enzyme activity be used as a measure of stress tolerance?
(Springer, Dordrecht, 2013)
A causal relationship between salinity and oxidative stress tolerance and a suitability of using root antioxidant activity as a biochemical marker for salinity tolerance in barley was investigated. Net ion fluxes were ...
Decalcification resistance of alkali-activated slag
(Elsevier Science Bv, Amsterdam, 2012)
This paper analyses the effects of decalcification in concentrated 6 M NH4NO3 solution on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/A-S 42.5 N) was used as a ...
Electrodeposition of Zn-Mn alloys at high current densities from chloride electrolyte
(Springer, New York, 2013)
The Zn-Mn alloy electrodeposition on a steel electrode in chloride electrolyte was investigated with the aim of obtaining deposits with as high as possible Mn percent. It was found that the deposition current density and ...
