Further degradation product of hyperforin from Hypericum perforatum (St. John's Wort)
(Elsevier, 2003)
Repeated examination of the aerial parts of Hypericum Perfomtum yielded a new degradation product of hyperforin (1) namely deoxyfurohyperforin A (2), together with the previously identified furohyperforin (3), furoadhyperforin ...
Catalytic incineration of ethylene oxide in the packed bed reactor
(Elsevier, 2006)
Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions ...
The determination of quantitative jugolone content dynamics and the antioxidant activity in the extract of green walnut (Juglans regia L.) fruits / Određivanje dinamike kvantitativnog sadržaja juglona i antioksidativne aktivnosti u ekstraktu ploda mladog oraha (Juglans regia)
(Journal of Scientific Agricultural Research, 2007)
Fruits from three walnut cultivars were picked in three terms with the aim to determine the optimal harvesting time of green walnut fruits for the improvement fruit brandies. Quantity of juglone and its antioxidant activity ...

Malaria is one of the most deadly diseases in world affecting more than 500 million people with over 2 million deaths per year. Four species of Plasmodium cause human disease: Plasmodium vivax (P. vivax), Plasmodium malarie ...
Carbon-supported hydrous ruthenium oxide composite as electrochemical supercapacitors. 3 - Capacitive Properties of the Composites / Kompozitni materijal hidratisani rutenijum oksid / ugljenik kao elektrohemijski superkondenzator 3. Kapacitivna svojstva kompozita
(Association of Chemical Engineers of Serbia, 2007)
Preparation of hydrous ruthenium oxide/carbon black nanocomposite material was performed by the impregnation method starting from hydrous RuO2 sol as a precursor. Black Pearls 2000 (R) (BP) and Vulcan (R) XC-72 R (XC) was ...
Morphology and phase composition of Ni-Co alloy powders electrodeposited from ammonium sulfate-boric acid electrolyte
(Materials Science Forum, 2006)
In this paper the morphology of Ni-Co powders electrodeposited from ammonium sulfate-boric acid containing electrolyte is investigated as a function of alloy powder composition. Composition of the electrolyte, i.e. the ...
A QSAR study of acute toxicity of N-substituted fluoroacetamides to rats
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Acute toxicity in vivo toward rats, of nineteen N-alkyl and N-cycloalkyl fluorocetamides [F-CH2-C(O)-NH-R] was correlated with their structure-dependent properties. Used descriptors are: molecular weights (M-w) and heat ...
Hydrogen Evolution on Zeolite Supported Platinum Clusters
(Wiley-VCH, 2003)
NaX type zeolite was loaded with platinum, by the thermal decomposition of Pt(II) acetylacetonate, up to the Pt/NaX mass ratio 0.174. The sample, dispersed on a glassy carbon rotating disc, was used in slightly acidic ...
Kvalitet podzemnih voda u području Zapadnobačkog okruga / The Quality of Underground qaters in the Region of West Bačka
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The population and the industry in the region of West Backa are supplied with underground water which is specific in its quality due to higher content of organic substance, higher pH values, the presence of hydrogen-sulphide ...
Relevance of the capacity of phosphorylated fructose to scavenge the hydroxyl radical
(Elsevier, 2009)
The hydroxyl radical (radical dotOH) has detrimental biological activity due to its very high reactivity. Our experiments were designed to determine the effects of equimolar concentrations of glucose, fructose and mannitol ...
