The comparison of sample extraction procedures for the determination of cations in soil by IC and ICP-AES
(Versita, Warsaw, 2011)
This paper presents the extraction of cations from a soil sample, type ranker on serpentinite, in deionized water, by use of three different extraction techniques. The first extraction technique included the use of a rotary ...
Electrochemical synthesis and corrosion behavior of polyaniline-benzoate coating on copper
(Elsevier Science Sa, Lausanne, 2011)
Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25 mA cm(-2), from aqueous solution of 0.3 mol dm(-3) sodium ...
Simultaneous Determination of Pb and Cd Traces in Water Samples by Anodic Stripping Voltammetry Using a Modified GC Electrode
(Wiley-Blackwell, Malden, 2011)
The determination of Pb and Cd with a Nafion-modified glassy carbon electrode and Cu-DPABA complex (Cu-DPABA NA/GCE; DPABA is methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl-benzoate) as an alternative electrode for ...
Correlation between structure, retention and activity of cholic acid derived cis-trans isomeric bis-steroidal tetraoxanes
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
Both quantitative structure-retention (QSRR) and quantitative structure-activity relationship (QSAR) studies have been performed to correlate the molecular characteristics of seven pairs of cis-trans isomeric bis-steroidal ...
Annulations of isoquinoline and beta-carboline ring systems: synthesis of 8-oxoprotoberberine derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Annulation processes of isoquinoline and p-carboline compounds have been investigated leading to synthetic routes for the preparation of 8-oxoprotoberberine derivatives. The key steps combined a diene formation/Diels-Alder ...
Removal of Cu2+ ions using hydrogels of chitosan, itaconic and methacrylic acid: FTIR, SEM/EDX, AFM, kinetic and equilibrium study
(Elsevier, 2011)
A removal of Cu2+ ions from aqueous solutions onto hydrogels of chitosan. itaconic and methacrylic acid has been investigated using batch adsorption technique. The extent of adsorption was investigated as a function of pH, ...
Fatty Acid Profiles of Four Wild Mushrooms and Their Potential Benefits for Hypertension Treatment
(Mary Ann Liebert Inc, New Rochelle, 2011)
Mushrooms are useful in balancing human diet and treating different health problems. The main determinant of the fluidity of erythrocyte membranes and rheologic properties of blood is the lipid composition of the membrane, ...
Investigation of bioremediation potential of zymogenous bacteria and fungi for crude oil degradation
(Springer Heidelberg, Heidelberg, 2011)
Bioremediation potential of bacteria and fungi isolated from sludge samples has been investigated (Danube alluvium, Panevo, Serbia). Total isolated microorganisms were divided into three parts. One part was added with ...
Blackberry Seed Extracts and Isolated Polyphenolic Compounds Showing Protective Effect on Human Lymphocytes DNA
(Wiley-Blackwell, Hoboken, 2011)
The tentative identification of seed extracts from 3 cultivars of blackberry (blackberry seed extracts [BSEs]) constituents was performed by LC/UV/MS technique. The identified compounds belonged to ellagitannins, galic ...
Composition of the Defensive Secretion in Three Species of European Millipedes
(Springer, Dordrecht, 2011)
Three European julid species, Cylindroiulus boleti, Leptoiulus trilineatus, and Megaphyllum bosniense, secrete mixtures of up to 12 different quinones. The major components in these species are 2-methoxy-3-methyl-1,4-benzoquinone ...
