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 ...
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, ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production
(Srpsko hemijsko društvo, Beograd, 2005)
Fe-Mo alloys were electrodeposited from a pyrophosphate bath using a single diode rectified AC current. Their composition and morphology were investigated by SEM, optical microscopy and EDS, in order to determine the ...
Investigation of sintering kinetics of NiO using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2004)
Sintering kinetics of NiO was investigated using photoacoustic spectroscopy. This method was used to follow the change of phase and amplitude of the photoacoustic signal of nickel-oxide samples sintered at 1373 K for 15-240 ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
An EPR spin-probe and spin-trap study of the free radicals produced by plant plasma membranes
(Srpsko hemijsko društvo, Beograd, 2005)
Plant plasma membranes are known to produce superoxide radicals, while the production of hydroxyl radical is thought to occur only in the cell wall. In this work it was demonstrated using combined spin-trap and spin-probe ...
Visualization of artificial lignin supramolecular structures
(Hindawi-Wiley, 2000)
In this paper we are presenting the results of our environmental scanning electron microscopy (ESEM) investigation of the lignin model compound-enzymatically polymerized coniferyl alcohol, also known as dehydrogenate polymer ...
Starosne promene u sadržaju insulin - sličnom faktora rasta i u mozgu pacova / Age-related changes in the content of insulin: Like growth factor-l in rat brain
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2002)
Vršena su istraživanja insulinu sličnog faktora rasta (IGF-I) na mišićno i koštano tkivo, ali je posvećena mala pažnja efektu na mozak u toku starenja. Mi smo ispitivali sadržaj IGF-I u moždanom tkivu pacova različite ...
Oxygen reduction at platinum nanoparticles supported on carbon cryogel in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2007)
The oxygen reduction reaction was investigated in 0.1 M NaOH solution, on a porous coated electrode formed of Pt particles supported on carbon cryogel. The Pt/C catalyst was characterized by the X-ray diffraction (XRD), ...
Antioxidant Properties of Phenolics in Castanea sativa Mill. Extracts
(University of Zagreb, 2009)
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against ...
