Frequency-response-controlled multiple-resonator-based harmonic analysis
(Hertford : The Institution of Engineering and Technology, 2018)
This Letter proposes a modified method for the dynamic harmonic analysis of signals with non-stationary harmonics, which is based on the previously proposed multiple-resonator observer structure. An optimisation technique ...
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 ...
Assessment of arsenic and mercury contamination in the Tisa River sediments and industrial canal sediments (Danube alluvial formation), Serbia
(Taylor and Francis Inc., 2012)
The purpose of this study was to examine the levels of As and Hg and mobility of these contaminants in the sediments of the River Tisa and canal sediments (alluvial formation of the Danube River, Serbia), in order to ...
Trace element study in Tisa River and Danube alluvial sediment in Serbia
(Irtces, Beijing, 2013)
The contaminated sediment serves as a long-term source of toxic elements, since that mobility and transport in the environment of these elements are strongly influenced to associated solid phase. In this study, the modified ...
Comparative Spectroscopic Characterization of the Basic and the Higher Fullerenes
(Taylor & Francis Inc, Philadelphia, 2013)
The basic C-60 and C-70, and the higher fullerenes, mainly C-76 and C-84, were extracted by original procedures, with p-xylene and the mixture of xylenes from the samples of initial carbon soot, produced in electrical arc. ...
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 ...
Accumulation and seasonal variation of toxic and trace elements in tissues of Cyprinus carpio from semi-intensive aquaculture ponds
(Edp Sciences S A, Les Ulis Cedex A, 2018)
The aim of this study was to assess the accumulation and seasonal variations of 20 toxic and trace elements in the abdominal and dorsal muscle (DM), liver and gut contents (GCs) of Cyprinus carpio, and in the sediments and ...
Synthesis, characterization and biological activities of N-heteroaromatic hydrazones and their complexes with Pd(II), Pt(II) and Cd(II)
(Springer, Dordrecht, 2010)
Condensation derivatives of ethyl hydrazinoacetate with 2-formylpyridine and quinoline-2-carboxaldehyde were synthesized. Pd(II), Pt(II) and Cd(II) complexes with the 2-formylpyridine derivative and a Cd(II) complex with ...
Implications of oxidative stress in occupational exposure to lead on a cellular level
(Taylor & Francis Ltd, Abingdon, 2015)
The aim of this study was to determine oxidative alterations leading to cellular dysfunctions in Pb-exposed subjects by evaluating damage to all major classes of biomolecules in the cell, lipid peroxidation, protein and ...
A Comparative Study of DNA Binding and Cell Cycle Phase Perturbation by the Dinuclear Complex of Cd(II) with the Condensation Product of 2-Acetylpyridine and Malonic Acid Dihydrazide N ',N ' 2-bis[(1E)-1-(2-pyridyl) ethylidene] propanedihydrazide
(Wiley-Blackwell, Malden, 2011)
Organometallic Cd(II) compounds have recently attracted attention for their anticancer activity. The interaction of the dinuclear complex of Cd(II) with the condensation product of 2-acetylpyridine and malonic acid ...
