Kvalitet podzemnih voda u području Zapadnobačkog okruga / The Quality of Underground qaters in the Region of West Bačka
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The population and the industry in the region of West Backa are supplied with underground water which is specific in its quality due to higher content of organic substance, higher pH values, the presence of hydrogen-sulphide ...
Bifidogenic effect of the infant formulas: In vitro investigations / In vitro ispitivanje bifidogenog efekta infant formula
(Zbornik radova Tehnološkog fakulteta, Leskovac, 2007)
Bifidogenic effect is growth stimulation of bifidogenic bacteria - probiotics in the intestinal tract by the effect of food ingredients which are prebiotics for these bacteria. Beside nutritive and biological values, ...

(Zbornik radova Tehnološkog fakulteta, Leskovac, 2007)
We examined effect of α-tocopherol addition and influence of nitric oxide from sodium nitroprusside (SNP) on free thiol content and SOD activity in exponentially growing K562 cells (human erythroleukaemia) in RPMI 1640 ...
Interactions of the anti-tumor sesquiterpene hydroquinone avarol with DNA in vitro / Interakcije antitumorskog seskviterpenskog hidrohinona avarola sa DNA in vitro
(Serbian Chemical Society, 2007)
Changes in electrophoresis pattern after interaction of supercoiled plasmid pBR322 DNA with avarol was studied at a micromolar concentration of reactants under mild reaction conditions. Interactions of avarol with linear ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...

(Serbian Chemical Society, 2007)
Six newly synthesized heterocyclic (2-nitrophenyl)piperazines, with a specific structure of the heteroaryl group, whichmimics the catechol moiety of dopamine (benzimidazoles and substituted benzimidazoles), were evaluated ...
Radical reactions of xanthates: Annulation of the cyclopentene ring / Radikalske reakcije ksantata : anelacija ciklopentenovog prstena
(Belgrade : Serbian Chemical Society, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Determination of adsorption capacity under static conditions / Odredjivanje adsorpcionog kapaciteta u statičkim uslovima
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The adsorption process are more and more frequently applied in water treatments. The choice of the adsorption medium depends on the adsorption capacity. The adsorption capacity in statical conditions should always preceeds ...
Oxidation of dibenzothiophene as a model substrate for the removal of organic sulphur from fossil fuels by iron(III) ions generated from pyrite by Acidithiobacillus ferrooxidans / Oksidacija dibenzotiofena kao model-supstrata za izdvajanje organskog sumpora iz fosilnih goriva dejstvom gvožđe(III)-jona generisanog iz pirita pomoću Acidithiobacillus ferrooxidans
(Serbian Chemical Society, 2007)
Within this paper a new idea for the removal of organically bonded sulphur from fossil fuels is discussed. Dibenzothiophene (DBT) was used as a model compound of organicmolecules containing sulphur. This form of ...
