The effect of perpendicularly oriented magnetic field on the formation of very disperse iron structures / Uticaj vertikalno orijentisanog magnetnog polja na formiranje veoma disperznih struktura gvožđa
(Serbian Chemical Society, 2006)
Iron deposits obtained without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). It was found that the iron deposit obtained under a perpendicularly oriented magnetic ...
The chemical characteristics of soil which determine phosphorus partitioning in highly calcareous soils / Hemijske karakteristike visoko-krečnjačkih zemljišta koje određuju raspodelu fosfora
(Serbian Chemical Society, 2006)
Phosphorus fractions from three highly calcareous soils (average, 24.9 ± 4.8 %CO3 2-) from sampling sites with a Mediterranean climate were isolated by sequential extraction. In order to provide a more reliable basis for ...
Influence of chloride ions on the open circuit potentials of chromium in deaerated sulfuric acid solutions / Uticaj hloridnih jona na potencijal otvorenog kola hroma u deaerisanim rastvorima sumporne kiseline
(Serbian Chemical Society, 2006)
Open circuit potential measurements and cyclic voltammetry of chromium in deaerated aqueous H2SO4 solution of pH 1 without and containing NaCl in the concentration range 0.5 - 4 M revealed that chromium exhibits two stable ...
Reduction of carbon monoxide emission from a solid-fuel thermo-accumulation furnace
(VINCA Institute of Nuclear Sciences, 2006)
Many households in Serbia, using electric thermo-accumulation furnaces for heating, have been forced to find an alternative solution, due to a significant increase in electricity prices during the last decade. A possible ...

(Belgrade : Vinča Institute of Nuclear Sciences, 2006)
The paper presents the results achieved by the project financed by Ministry of Science and Environmental Protection of Serbia during the period 2003-2005. The purpose of the project was determination methodology for designing ...
Preparation of sedimentary organic matter concentrates by microbiological methods / Pripremanje koncentrata organske supstance primenom mikrobioloških metoda
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
Investigation on combined bacterial demineralization of sediments i.e. removal of silicates (desilicification) by Bacillus circulans and removal of pyrite (depyritization) by Acidithiobacillus ferrooxidans are reviewed in ...
(1->3)-β-D-glucan from saccharomyces cerevisiae, preparation, characterization and chemical modification: Introducing carbonyl groups into the polysaccharide chain / (1->3)- β-D-glukan iz saccharomyces cerevisiae - dobijanje, karakterizacija i hemijska modifikacija uvođenjem karbonilnih grupa u polisaharidni niz
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
A number of polysaccharides with [3-glycosidic linkage are widespread in a variety of sources. All have a common structure, the (1->3)- β -D-glucan backbone is essential. They have attracted attention because of bioactive ...
