Geodesic infinitesimal deformations of generalized Riemannian space
(Birkhaeuser Verlag AG, 2022-05-11)
Infinitesimal deformations of subspaces of a generalized Riemannian
space are studied in this paper. Variations of some geometric
objects are found. Necessary and sufficient conditions which provide the
existence of a ...
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. ...
Boron-doped diamond electrode as efficient sensing platform for simultaneous quantification of mefenamic acid and indomethacin
Mefenamic acid and indomethacin, medicaments belonging to the group of non-steroidal anti-inflammatory agents, were determined separately and simultaneously at anodically prepared BDDE. Differential pulse voltammetry was ...
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 ...
Dinuclear silver(I) complexes with a pyridine-based macrocyclic type of ligand as antimicrobial agents against clinically relevant species: the influence of the counteranion on the structure diversification of the complexes
New dinuclear silver(I) complexes with N,N’,N’’,N’’’-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc), [Ag2(NO3)(tpmc)]NO3·1.7H2O (1), [Ag2(CF3SO3)2(tpmc)] (2), and [Ag2(tpmc)](BF4)2 (3) were synthesized ...
Evaluation of azamethiphos and dimethoate degradation using chlorine dioxide during water treatment
Chlorine dioxide (ClO2) degradation of the organophosphorus pesticides azamethiphos (AZA) and dimethoate (DM) (10 mg/L) in deionized water and in Sava River water was investigated for the first time. Pesticide degradation ...
Degradation Products, Mineralization, and Toxicity Assessment of Pesticides Malathion and Fenitrothion
The aim of this study was to investigate, analyze, and compare applied techniques suitable for achieving efficient removal of organophosphorus pesticides (OPPs) (malathion and fenitrothion) from aqueous solutions and analyze ...
Easily Prepared Co3O4 Doped Porous Carbon Material Decorated with Single‐wall Carbon Nanotubes Applied in Voltammetric Sensing of Antioxidant α‐lipoic Acid
The homemade, porous carbon material, thermolysis prepared from Novolac phenol-formaldehyde resin, in situ modified with Co3O4 nanoparticles and mixed with single-wall carbon nanotubes, was used in selective sensing of ...
First electrochemistry of herbicide pethoxamid and its quantification using electroanalytical approach from mixed commercial product
This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson ...
