Assessment of landscape sensitivity based on geochemical characteristics of sediments (Kremna basin)
(Romania : Editura Universităţii din Oradea, 2018)
The scale of human impacts on the natural environment is now considerably larger than at any point in history. The concept of geomorphic sensitivity can help to understand the rate, magnitude and nature of landscape ...
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 ...

Printed Antenna Array with Flat-Top Radiation Pattern
(Berlin : Walter De Gruyter Gmbh, 2018)
printed antenna array consisting of 10 wide-band symmetrical pentagonal dipoles is presented. The feed network of impedance transformers is employed to provide appropriate amplitude and phase distribution necessary to ...
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 ...
Electrochemical supercapacitors: Operation, components and materials
(Association of Chemical Engineers of Serbia, 2018)
Supercapacitors are the best choice when there is a need to deliver high power to the consumer or to store energy. Hybrid supercapacitors with their beneficial characteristics can somewhat overcome the basic lack of ...
Antioxidant, Antimicrobial and Antiproliferative Activities of Synthesized 2,2,5,5-Tetramethyl-9-aryl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione Derivatives
(Croatian Chemical Soc, Zagreb, 2018)
Ten biologically active 2,2,5,5-tetramethy1-9-aryl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione derivatives were synthesized and their structures were confirmed by IR, H-1 and C-13 NMR spectroscopy and mass spectrometry. ...
Alkylamino and aralkylamino derivatives of avarone and its mimetic as selective agents against non-small cell lung cancer cells, their antibacterial and antifungal potential / Aлкиламино и аралкиламино деривати аварона и његовог миметика као селективни агенси према ћелијама неситноћелијског карцинома плућа, њихов антибактеријски и антифунгални потенцијал
(Serbian Chemical Society, 2018)
In this paper, the synthesis of fourteen alkylamino and arylamino derivatives of sesquiterpene quinone avarone and its model compound tert-butylquinone is described. Branched, cyclic, allylic and benzylic alkylamino/arylamino ...
Al,Fe,Ni-pillared bentonite in the catalytic wet peroxide oxidation of the textile dye Acid Yellow 99
(Springer Netherlands, 2018)
The main goal of this work was to prove that nickel containing Al,Fe pillared bentonites have enhanced catalytic properties. The chosen test system was the catalytic wet peroxide oxidation (CWPO) the Acid Yellow 99 dye ...
Uncertainty of using habitat fidelity in biomonitoring based on benthic diatoms - the Raška River case study
(Springer, 2018)
Epilithic diatoms are frequently recommended for river biomonitoring, while much less emphasis is placed on epiphytic communities.
This study considers use of epiphytic and epilithic diatom communities from the Raška River ...
