Application of Electrochemically Synthesized Ferrates (VI) for the Removal of Th(IV) From Natural Water Samples
The efficiency of the application of electrochemically generated Na2FeO4, for the purpose of the elimination of Th(IV) ions from water samples as coagulating agent was investigated. Th is a radioactive element often used ...
Influence of mode coupling on angular division multiplexing in seven-core plastic optical fibers
(IOP Science, 2020-05-11)
We propose an angular division multiplexing in new designed multicore plastic optical fiber
with seven cores arranged in a hexagonal array. The influence of mode coupling on two-channel
angular division multiplexing ...
A transmission length limit for space division multiplexing in step-index silica optical fibers
(Taylor & Francis, 2019-08-28)
By solving the power flow equation, we investigate the influence of mode coupling on space division
multiplexing capability of three multimode step-index silica optical fibres with a different strengths
of mode coupling. ...
Effective doses estimated from the results of Direct Radon and Thoron Progeny Sensors (DRPS/DTPS), exposed in selected regions of Balkans
The main contribution to population exposure is due to radon and thoron progenies and not radon itself. The aim of this study was therefore to estimate annual effective dose using the results of Direct Radon and Thoron ...
The total curvature of knots under second-order infinitesimal bending
(World Scientific Publishing Co. Pte. Ltd., 2019-01-03)
In this paper, we consider infinitesimal bending of the second-order of curves and
knots. The total curvature of the knot during the second-order infinitesimal bending is
discussed and expressions for the first and the ...
Infinitesimal bending of knots and energy change
(World Scientific Publishing Co. Pte. Ltd., 2019-09-12)
We discuss the infinitesimal bending of curves and knots in R3. A brief overview of the results on the infinitesimal bending of curves is outlined. Change of the Willmore energy, as well as of the Möbius energy under ...
First electrochemical investigation of organophosphorus pesticide azametiphos and its quantification using electroanalytical approach
In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. ...
Synthesis, characterization and biological study of new dinuclear zinc(II) and nickel(II) octaaza macrocyclic complexes
Two new nitrato complexes of zinc and nickel with 1,4,8,11-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc), have been synthesized and characterized. The IR spectral peaks showed that the coordinated and ...
Analysis of adaptive e‐learning systems with adjustment of Felder‐Silverman model in a Moodle DLS
(Wiley, 2020-05-07)
E‐learning, as a complex system, includes distance learning, teaching materials in various forms and shapes, group and individual learning processes, as well as interactive and tutorial work. To increase the effectiveness ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
