Study of Dielectric Behavior and Electrical Properties of Hematite alpha-Fe2O3 Doped with Zn
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Quantitative determination of poly(vinylpyrrolidone) by 'On-line' pyrolysis coupled with gas chromatography / Kvantitativno određivanje poli(vinilpirolidona) primenom 'On-line' pirolize kuplovane sa gasnom hromatografijom
(Savez hemijskih inženjera, Beograd, 2012)
'On-line' pyrolysis coupled with gas chromatography (GC) was performed for quantitative determination of poly(vinylpyrrolidone) (PVP) in wastewater sample. Gas chromatography-mass spectrometry (GC-MS) showed that the main ...

The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Molecular Characterization of LMW-GS Genes from C, N, U and S-s Genomes among Aegilops Species
(Akademiai Kiado Zrt, Budapest, 2012)
In this work, 9 novel LMW-GS genes (6 LMW-m and 3 LMW-i type) from 4 diploid and 1 tetraploid Aegilops species were amplified and cloned by allelic-specific PCR. Analysis of the deduced amino acid sequences showed that 7 ...
Bionomy of spruce bud scale, Physokermes piceae (schrank) (Hemiptera: Coccidae) in the Belgrade area, Serbia
(Srpsko biološko društvo, Beograd, i dr., 2012)
Spruce bud scale, Physokermes piceae, develops on the genus Picea. Large colonies of this species are constantly present on Picea abies in green areas in the Belgrade territory, causing the drying of needles, branches and ...
