Weed vegetation of small grain crops in Serbia: environmental and human impacts
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2009)
Weed flora of winter and spring small grain crops (wheat, barley, oats, and rye) was surveyed in lowland and mountainous areas of the central part of Serbia, which are dissimilar in environmental conditions, primarily ...
Oilseed rape (Brassica napus L.) genotypic variation in response to boron deficiency
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2012)
Boron efficiency of 16 oilseed rape genotypes was tested using both hydroponic and pot-soil growing techniques. From the nutrient solution experiment (0.1 and 10 mu M B), 4 representative contrasting genotypes were selected ...
Intracellular pH as an indicator of viability and resuscitation of Campylobacter jejuni after decontamination with lactic acid
(Elsevier, Amsterdam, 2009)
The aim of the study was to determine intracellular pH (pH(i)) as an indicator of the physiological state of two Campylobacter jejuni strains (603 and 608) at the single cell level after bactericidal treatment with lactic ...
Comparison of tillage systems according to fuel consumption
(Pergamon-Elsevier Science Ltd, Oxford, 2010)

Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2012)
The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average ...
The investigation of phenol removal from aqueous solutions by zeolites as solid adsorbents
(Elsevier, Amsterdam, 2010)
This work reports results on phenol adsorption from aqueous solutions on synthetic BEA (beta) and MFI (ZSM-5) zeolites, studied by heat-flow microcalorimetry. For the sake of comparison, the adsorption was performed on ...
Oxidation of CO over Ru containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2006)
Perovskite type catalysts La0.7Sr0.3Cr1-xRuxO3 (0.025 lt = x lt = 0.100) were synthesized by annealing a mixture of metal oxides and carbonates gradually up to 1000 degrees C in air, and characterized by XRPD, XPS, TPD, ...
