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 ...
Bioactive Compounds in Wild, In vitro Obtained, Ex vitro Adapted, and Acclimated Plants of Centaurea davidovii (Asteraceae)
(Natural Products Inc, Westerville, 2015)
In vitro cultures were initiated from a single seed of Centaurea davidovii. Whole plantlets were regenerated and cultivated for several months on agar-solidified nutrient media differing by their composition: basal MS ...
An adsorption-based mercury sensor with continuous readout
(Springer, New York, 2013)
A novel readout procedure for a mercury sensor has been proposed. The sensor is based on the surface adsorption. Mercury vapor is adsorbed at the surface of a thin gold layer patterned into four meanders which are connected ...
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 ...
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 ...
An Assessment of the Chemical Characteristics of Early Diagenetic Processes in a Geologically Well-defined Brown Coal Basin
(Taylor & Francis Inc, Philadelphia, 2015)
The characteristics of early diagenetic processes, which influenced the composition of the organic matter of coals from the Krepoljin coal basin, Serbia, Miocene age was assessed by statistical correlation analysis and ...
Degradation of azithromycin using Ti/RuO2 anode as catalyst followed by DPV, HPLC-UV and MS analysis
(Versita, Warsaw, 2017)
The electrodegradation of azithromycin was studied by its indirect oxidation using dimensionally stable Ti/RuO2 anode as catalyst in the electrolyte containing methanol, 0.05 M NaHCO3, sodium chloride and deionized water. ...
Evaluation of heavy metal contamination in sediments using the method of total digestion and determination of the binding forms-Tisa River Basin, Serbia
(Taylor and Francis Inc., 2010)
This paper describes an approach for the evaluation of metal contamination in sediment, using the determination of binding forms of elements (sequential extraction method), the total element content (digestion method), as ...
P-nitrophenol electro-oxidation on a btma(+)-bentonite-modified electrode
(Clay Minerals Soc, Chantilly, 2012)
Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, ...
