The thermal degradation of aqueous polyurethanes with catalysts of different selectivity
(Elsevier Science Sa, Lausanne, 2007)
The thermal,ability of aqueous polyurethanes has been measured by applying the thermogravimetric analysis, The aqueous polyurethanes (aqPUR) with catalysts of different selectivity have been studied by use of the dynamic ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier Science Bv, Amsterdam, 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier Sci Ltd, Oxford, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
Boron uptake by the root cortex symplast of tomato and pea plants: evidence for low-boron-induced active transport
(Csiro Publishing, Clayton, 2007)
The objective of this research was to test the hypothesis of the existence of an active boron ( B) uptake into the cortical cells induced by low B supply. The uptake of B was characterised in two tomato ( Lycopersicon ...
Kinetics of Cu2+ binding to the poly(acrylic acid) hydrogel
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Isothermal kinetics of copper (ion) binding to poly(acrylic acid) (PAA) hydrogel at 20, 25, 35 and 45 C was investigated. Isothermal conversions and kinetic curves of Cu2+ binding to the PAA hydrogel were determined. It ...
Analysis of self-(in)compatibility in apricot cultivars using fluorescence microscopy
(Taylor & Francis Ltd, Abingdon, 2007)
Self-incompatibility is a common feature in fruit species of the genus Prunus, especially in sweet cherries and almonds. In apricot (Prunus armeniaca L.), although cultivars of the European ecogeographical group are generally ...
Weeding of cultivated chamomile in Serbia
(Int Soc Horticultural Science, Leuven 1, 2007)
Survey of weeds occurring in cultivated chamomile was conducted at three sites of the northern east and central west region in Serbia, differing in climate, soil and applied fertilizers, in order to estimate diversity and ...
Synthesis and characterization of novel Cd(II), Zn(II) and Ni(II) complexes with 2-quinolinecarboxaldehyde selenosemicarbazone. Crystal structure of bis(2-quinolinecarboxaldehyde selenosemicarbazonato)nickel(II)
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
New complexes of Cd(II), Zn(II) and Ni(II) with 2-quinolinecarboxaldehyde selenosernicarbazone (Hqasesc) were synthesized and structurally characterized. The structure of the ligand, Cd(II) and Zn(II) complexes was determined ...
In vitro effect of plant essential oils on growth of some soil-borne pathogens
(Int Soc Horticultural Science, Leuven 1, 2007)
A study of antifungal and antibacterial activity of 17 commercially available essential oils was carried out in vitro using cultures of Pythium sp., Fusarium oxysporum f, sp. lycopersici, F. oxysporum f. sp. pisi, Verticillium ...
Choosing type of chamomile harvester based on current value of usage costs
(Int Soc Horticultural Science, Leuven 1, 2007)
The harvesting is a very important phase during the process of chamomile production and has to be carried out in optimal agro-technical terms in order to achieve better quality of chamomile, i.e. high content of ether oil. ...
