Depleted uranium mobility and fractionation in contaminated soil (Southern Serbia)
(Springer Heidelberg, Heidelberg, 2008)
Goal, Scope and BACKGROUND: . During the Balkan conflict in 1999, soil in contaminated areas was enriched in depleted uranium (DU) isotopic signature, relative to the in-situ natural uranium present. After the military ...
Cell immobilization: past, present and future prospects

Impact of the population of spoilage microflora on the growth of Listeria monocytogenes on frankfurters
(Int Assoc Food Protection, Des Moines, 2006)
Approximately 100 CFU/cm(2) of a five-strain mixture of Listeria monocytogenes was coinoculated onto frankfurters with three different concentrations (10(2), 10(4), and 10(6) CFU/cm(2)) of an undefined spoilage microflora ...
Oak acorn, polyphenols and antioxidant activity in functional food
(Elsevier Sci Ltd, Oxford, 2006)
In this paper, are presented the results of physical and chemical investigations of differently treated samples of oak acorn. The aim of this investigation is to estimate the influence of thermal treatment on physical and ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Transformation of petroleum saturated hydrocarbons during soil bioremediation experiments
(Water, Air, and Soil Pollution, 2008)
This paper presents transformations of saturated hydrocarbons of petroleum type pollutants during ex situ bioremediation of soil on the pilot heap (halde), during a period of 6 months, within the grounds of Petroleum ...
The mutual effect of extracellular Ca2+, abscisic acid, and pH on the rate of stomatal closure
(New York Acad Sciences, New York, 2005)
An analysis of the rate of stomatal closure in epidermal strips of Commelina communis L. induced by different calcium concentrations (10 nM to 1 mM) demonstrated a biphasic dependency, the initial process of closure being ...
Barium titanate screen-printed thick films
(Elsevier Sci Ltd, Oxford, 2002)
Barium titanate (BT) thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. After homogenization and milling in a high-energy vibro mill, the powders were calcined at 700 degreesC for 2 h ...
Effects of the acrylic polyol structure and the selectivity of the employed catalyst on the performance of two-component aqueous polyurethane coatings
(MDPI, BASEL, 2007)
Two kinds of aqueous acrylic polyols (single step and multi step synthesis type) have been investigated for their performance in the two-component aqueous polyurethane application, by using more selective catalysts. The ...
Spectroscopic characteristics of highly selective manganese catalysis in acqueous polyurethane systems
(MDPI, BASEL, 2006)
The latest investigations on producing more efficient catalytic aqueous polyurethane systems are in the domain of metal complexes with mixed ligands. In our previous research works, the high selectivity for the isocyanate-hydroxyl ...
