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 ...
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 ...
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 ...
Cobalt impregnated pillared montmorillonite in the peroxymonosulfate induced catalytic oxidation of tartrazine
(Springer Netherlands, 2018)
Aluminum pillared montmorillonite impregnated with cobalt (CoAP) was synthesized and characterized using chemical analysis, XRD and N2-physisorption. CoAP was tested as a catalyst in the peroxymonosulfate (Oxone®) induced ...
