Toksičnost nikla i kadmijuma u četinama smrče: uticaj zasebnih i kombinovanih tretmana na peroksidaznu i superoksid-dismutaznu aktivnost / Toxicity of nickel and cadmium in spruce seedlings: Effect of separated and combined treatments on peroxidase and superoxide-dismutase activity
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 2003)
Proučavana je aktivnost slobodnih peroksidaza i superoksid-dismutaza izoenzimski profil peroksidaza i sadržaj metala u četinama dvogodišnjih smrča gajenih na zemljištu u koje su dodavani kadmijum i nikl u koncentracijama ...
Oxygen and light accelerate recovery from SO2-induced inhibition of leaf photosynthesis and from cytoplasmic acidification
(Elsevier GmbH, 2000)
Leaves of several plant species were illuminated either in air or in a gas atmosphere with reduced oxygen content, and photosynthesis and transpiration were recorded after brief exposure to high concentrations of SO2. ...
Estimation of neuronal population activity changes in rat cerebellum using one electrode
(Elsevier Science Inc, New York, 2004)
Activity of neuronal populations is usually measured with multielectrode systems. In this paper a procedure is described for estimating population activity changes in rat cerebellar cortex, using one microelectrode. Signals ...
Influence of the common varistor dopants (CoO, Cr2O3 and Nb2O5) on the structural properties of SnO2 ceramics
(Elsevier Science Inc, New York, 2004)
The influence of dopants commonly used in SnO2 varistor ceramics, such as CoO, Cr2O3 or Nb2O5, on the structural properties of SnO2 was investigated. Several SnO2-based ceramics containing only one of the dopants were ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Springer, New York, 2004)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Characterisation of dispersive systems using a coherer
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2002)
The possibility of characterization of aluminium powders using a horizontal coherer has been considered. Al powders of known dimension were treated with a high frequency electromagnetic field or with a DC electric field, ...
ZL-DHP lignin model compound at the air-water interface
(Elsevier, Amsterdam, 2002)
In this paper we present our surface chemistry studies of enzymatically polymerized, poly-coniferyl alcohol lignin model compound (dehydrogenate polymer a.k.a. ZL-DHP) at the air-water interface. Using the CHCl3/MeOH (5:1 ...
Study of the lignin model compound supramolecular structure by combination of near-field scanning optical microscopy and atomic force microscopy
(Elsevier, Amsterdam, 2004)
In this paper, we present a nanoscale study of the supramolecular structure of the dehydrogenate polymer (ZL-DHP) lignin model compound. The combination of near-field scanning optical microscopy (NSOM or SNOM) and atomic ...
Effect of bicarbonate on uptake and translocation of Fe-59 in two grapevine rootstocks differing in their resistance to Fe deficiency chlorosis
(Bundesanstalt Zuchtungs Forschung Kulturpflanzen, Siebeldingen, 2000)
In order to study the effect of high bicarbonate concentration in the root medium on root Fe-III reduction, Fe uptake and its translocation to the leaves, two rootstocks (Vitis riparia Michx., susceptible, and 41 B (Vitis ...
