Solvent and Structure Effects on Electronic Absorption Spectra of the Isomeric Pyridinecarboxylic Acids
(Springer, New York, 2014)
Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze ...
Characterization of polyaniline-based ammonia gas sensors prepared by means of spray coating and ink-jet printing
(American Scientific Publishers, 2014)
This work deals with the process of ammonia gas sensor fabrication and its detailed characterization. The sensor active layer was deposited from a polyaniline dispersion. The prepared polyaniline dispersion is based on ...
Metals in the sediment and liver of four fish species from different trophic levels in Tisza River, Serbia
(Taylor & Francis Ltd, Abingdon, 2014)
In aquatic environments metals originate from various natural and anthropogenic sources. The degree of contamination in fish tissues depends on the pollutant, fish species, their mode of feeding, sampling site and trophic ...
Non-isothermal reduction of silica-supported nickel catalyst precursors in hydrogen atmosphere: a kinetic study and statistical interpretation
(Springer, New York, 2014)
A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni mole ratios (0.20, 0.80 and 1.15). Non-isothermal reduction of Ni catalyst precursors was investigated by temperature-programmed ...
Heavy metal and trace element bioaccumulation in target tissues of three edible predatory fish species from bovan reservoir (Serbia)
(Parlar Scientific Publications, 2014)
Pikeperch (Sander lucioperca), catfish (Silurus glanis) and pike (Esox lucius) were collected from the Bovan Reservoir (Southeast Serbia), and samples of muscle, liver and gills were analyzed for Cu, Zn, Pb, Cd, Hg, Cr and ...
Dose-dependent survival of K562 cells subjected to irradiation, time course of endogenous enzyme activity and protective effect of applied superoxide dismutase
(Zerbinis Publications, 2014)
Purpose: Irradiation-generated reactive species are proven to affect the cell survival and antioxidant enzyme levels. Radioresistance is a phenomenon which includes many cell mechanisms and signaling pathways. Superoxide ...
Assessment of lipophilicity of some biologically active arylpiperazines by rptlc and multivariate analysis
(Taylor & Francis Inc, Philadelphia, 2014)
The chromatographic behavior of arylureas and arylacetamides derivatives with observed biological activity toward dopamine D-2 and 5-hydroxytryptamine 5HT(1A) receptors were examined by high-performance thin-layer ...
Chemical Composition of the Essential Oil of Geum rhodopeum
(Springer, New York, 2014)
Organic geochemical study of the lower miocene kremna basin, Serbia
(Polish Geological Soc, Krakow, 2014)
The Kremna Basin is located in south west Serbia, in the Zlatibor area, which is part of the Internal Dinarides. This basin is note worthy because of the type of bedrock drainage, which it represents. It was formed on ...
Preservation of diagenetic products of beta-carotene in sedimentary rocks from the Lopare Basin (Bosnia and Herzegovina)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2014)
Sedimentary rocks from the saline formation of the Lopare Basin were investigated. Sediments contain a moderate amount of immature to marginally mature algal organic matter deposited under slightly reducing to anoxic and ...
