Spectrofluorimetric and HPLC Determination of Morin in Human Serum
(Slovenian Chemical Society, 2009)
Morin is a flavonol antioxidant. In ethanol-water mixtures (70 wt% of ethanol) it reacts with Al3+ to give Al(Morin)(2) in the pH range 3-6. The conditional stability constant of this complex at 298 K was found to be log ...
Thermal Diffusivity of Single Crystal Bi0.9Sb0.1
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (001) were determined from PA photoacoustic phase and ...
Different roles of radical scavengers - ascorbate and urate in the cerebrospinal fluid of amyotrophic lateral sclerosis patients
(Taylor & Francis Ltd, Abingdon, 2010)
Ferrous iron, released from iron deposits in the motor cortex and other brain regions of amyotrophic lateral sclerosis (ALS) patients, participates in the Fenton reaction in cerebrospinal fluid (CSF) alongside H2O2, which ...

Moss species of the family Brachytheciaceae, Kindbergia praelonga (Hedw.) Ochyra and Kindbergia stokesii (Turn.) Ochyra, were preliminarily analysed for their fatty acid composition with the aim of studying the chemical ...
The anthropogenic impact on water quality of the river danube in Serbia: microbiological analysis and genotoxicity monitoring
(Srpsko biološko društvo, Beograd, i dr., 2011)
The aim of this work was to examine the impact of urban wastewaters on the water quality of the Danube River in Serbia. Samples of water and sediments for microbiological analysis and genotoxicity monitoring were collected ...
SiC Synthesis Using Natural Mg-Silicates
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600 degrees C). Carbothermal reduction process is greatly ...
Does overhead irrigation with salt affect growth, yield, and phenolic content of lentil plants?
(Srpsko biološko društvo, Beograd, i dr., 2012)
Overhead irrigation of lentil plants with salt (100 mM NaCl) did not have any significant impact on plant growth, while chlorophyll content and chlorophyll fluorescence parameter F-v/F-m were affected. Under such poor ...
