Transformation of a petroleum pollutant during soil bioremediation experiments
(Srpsko hemijsko društvo, Beograd, 2008)
The experiment of ex situ soil bioremediation was performed at the locality of the Oil Refinery in Pancevo (alluvial formation of the Danube River, Serbia) polluted with an oil type pollutant. The experiments of biostimulation, ...
A study of the adsorption thermodynamics of n-hexane on ion-exchanged X zeolites / Termodinamika adsorpcije n-heksana na jonski izmenjenim X zeolitima
(Srpsko hemijsko društvo, Beograd, 2005)
In this work, the free energy changes and entropy changes of adsorption of n-hexane on zeolites of the MxNa87-2xX (M=Co,Ni,Zn,Cd) type were determined using their isosteric sorption heats. It was found that the exchange ...
Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...
The effect of different levels of organic selenium on body mass, bodyweight gain, feed conversion and selenium concentration in some gilts tissues / Uticaj različitih nivoa organskog selena na telesnu masu, prirast, iskorišćavanje hrane i koncentraciju selena u pojedinim tkivima kod svinja
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2006)
Thirty-nine gilts, 82 days old, divided into 3 groups, were fed the main diet supplemented by 0; 0.3 and 0.6 mg Se/kg in the form of Seenriched yeast during 99 days. Selenium levels of 0.3 and 0.6 mg/kg diet led to no ...
Floral nectaries of basil (Ocimum basilicum): Morphology, anatomy and possible mode of secretion
(Elsevier Science Bv, Amsterdam, 2007)
Floral nectaries of Ocimum basilicum L. were studied using light, fluorescence and scanning electron microscopy. Each nectary forms an asymmetrical four-lobed disc at the base of the outer surface of the ovary. The three ...
