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, ...
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 ...
Contribution of Frenkel's theory to the development of materials science
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
The original and comprehensive research of Yakov Rich Frenkel in physics and physical chemistry of condensed states, nuclear physics, electrodynamics, science of sintering has significantly contributed to the development ...
Comparison of the swelling kinetics of a partially neutralized poly(acrylic acid) hydrogel in distilled water and physiological solution / Poređenje kinetike bubrenja hidrogela delimično neutralisane poli(akrilne) kiseline u destilovanoj vodi i fiziološkom rastvoru
(Srpsko hemijsko društvo, Beograd, 2007)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in distilled water and physiological solution at temperatures ranging from 20 to 40 ºC were determined. The possibility of applying both the ...
The influence of zeolite type added to cigarette blend on the changes of pyrolitic temperatures
(Savez hemijskih inženjera, Beograd, 2009)
Reduction of harmful tobacco smoke compounds, such as nitrosamines and polycyclic aromatic hydrocarbons (PAHs) could be particularly controlled by adjusting the cigarette pyrolitic conditions. One possible way to do that ...
Partial root drying irrigation technique: Practical application of drought stress signaling mechanism in plants / Tehnika delimičnog sušenja korenova - praktična primena signalnih mehanizama suše kod biljaka
(Srpsko biološko društvo, Beograd, i dr., 2009)
Partial root-zone drying (PRD) technique, a novel approach to watering crops, was developed on the basis of knowledge of root-to-shoot signaling in drying soil. The aim of the present paper was to investigate the effects ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
A survey of aphid parasitoids (Hymenoptera : Braconidae : Aphidiinae) of Southeastern Europe and their aphid-plant associations
(Springer Japan Kk, Tokyo, 2004)
The present work covers original information on the aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) of Southeastern Europe. The individual parasitoid species were reared from identified host aphid and plant ...
Total phenolics and phenolic acids content in low (Chrysopogon gryllus) and mediocre quality (Festuca vallesiaca) forage grasses of Deliblato Sands meadow-pasture communities in Serbia
(Czech Academy Agricultural Sciences, Prague, 2005)
Chrysopogon gryllus and Festuca vallesiaca are components of a number of meadow-pasture communities in Serbia. We performed the analyses of phenolics that influence quality and digestibility of grasses to a great extent. ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
