Assessment of heavy metal pollutants accumulation in the Tisza river sediments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Tisza River and its tributaries, and thereby used the sequential extraction method, geochemical normalization, the ...
Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
Antioxidant properties of raspberry seed extracts on micronucleus distribution in peripheral blood lymphocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
This study addresses in vitro effects of raspberry (Rubus idaeus) seed extracts (RSE) on the frequency of micronuclei. We evaluated the effects of three different extracts (50%, 80%, and 100% methanol) in doses of 1.4, ...
Statistical design of experiments of acid activation of smectite clay from Serbia and its bleaching capacity
(Wiley, Hoboken, 2009)
BACKGROUND: Serbian smectite clay has been activated using a response surface method with central composite design. Because, among the criteria of an edible oil, colour is the most important factor in the commercial value ...
Allergenicity and immunogenicity of the major mugwort pollen allergen Art v 1 chemically modified by acetylation
(Wiley-Blackwell Publishing, Inc, Malden, 2009)
Treating allergies with modified allergens is an approach to make the treatment safer and more efficient. Art v 1 is the most prominent allergen of mugwort pollen and a significant cause of hayfever around Europe. The aim ...
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 ...
Oxidation of formaldehyde and ethanol on Au(1 1 1) and Au(1 1 1) modified by spontaneously deposited Ru in sulfuric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The oxidation of formaldehyde and ethanol on both pure Au(1 1 1) and Au(1 1 1) modified by approximately 0.3 monolayer (ML) of spontaneously deposited Ru was studied by cyclic voltammetry (CV) in 0.5 M H2SO4 solution ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
Freshwater cyanobacterial blooms and primary liver cancer epidemiological studies in Serbia
(Journal of Environmental Science and Health - Part C Environmental Carcinogenesis and Ecotoxicology, 2009)
A large part of Central Serbia experiences continual shortage of sufficient ground water resources. For that reason, more than 20 reservoirs serve as drinking water suppliers. Significant and persistent cyanobacterial ...
Synthesis and characterization of self-assembled polyaniline nanotubes/silica nanocomposites
(American Chemical Society (ACS), 2009)
Self-assembled semiconducting, paramagnetic polyaniline nanotubes have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium in the presence of colloidal silica particles ...
