Synthesis and spectral characterization of asymmetric azines containing a coumarin moiety: The discovery of new antimicrobial and antioxidant agents
(2018-10-25)
Nine unsymmetrical azines containing a coumarin moiety were prepared by the reaction of the hydrazone of 4-hydroxy-3-acetylcoumarin with differently substituted aromatic aldehydes. The azines were fully spectrally ...
Total Normalcy of Knots
(Faculty of Sciences and Mathematics, University of Niš, 2019-01-01)
In this paper we consider first order infinitesimal bending of curves and knots. The total
normalcy of the knot during the first order infinitesimal bending is discussed and expressions for the first variation of the total ...
A new longipinane ketone from Achillea abrotanoides (Vis.) Vis.: chemical transformation of the essential oil enables the identification of a minor constituent
(Wiley-VHCA AG, Zurich, Switzerland, 2019-12-10)
Introduction: Minor plant constituents are difficult to identify due to the challenging
isolation and acquiring of reliable spectral data. Essential oils abound in such minor
constituents that might be of high importance ...
Speaker Recognition Using Constrained Convolutional Neural Networks in Emotional Speech
(Molecular Diversity Preservation International, 2022-03-16)
Speaker recognition is an important classification task, which can be solved using several
approaches. Although building a speaker recognition model on a closed set of speakers under neutral speaking conditions is a ...
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 ...
Design of a 2-Bit Neural Network Quantizer for Laplacian Source
(Molecular Diversity Preservation International, 2021-07-22)
Achieving real-time inference is one of the major issues in contemporary neural network applications, as complex algorithms are frequently being deployed to mobile devices that have constrained storage and computing power. ...
Optimization and validation of the kinetic spectrophotometric method for quantitative determination of the pesticide atrazine and its application in infant formulae and cereal-based baby food
(Wiley-VHCA AG, Zurich, Switzerland, 2019-05-11)
BACKGROUND: Pesticides are potentially toxic to humans and can produce both acute and chronic health effects, depending on the quantity and the ways in which a person is exposed. Exposure to pesticides can cause serious ...
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 ...
Boron-doped diamond electrode-a prestigious unmodified carbon electrode for simple and fast determination of bentazone in river water samples
Bentazone (BZ) is selective contact-past herbicide with suspected reproductive toxicity potential for human due to possible contamination of ground and surface waters. This work presents simple, rapid, sensitive and accurate ...
