Synthesis, characterization, antioxidant and antimicrobial activity of novel 5-arylidene-2-ferrocenyl-1,3-thiazolidin-4-ones
(Journal of Organometallic Chemistry, 2018-08)
Synthesis of twenty novel 5-arylidene-2-ferrocenyl-1,3-thiazolidin-4-ones has been achieved in good to excellent yields by the Knoevenagel condensation of 2-ferrocenyl-1,3-thiazolidin-4-ones with aromatic aldehydes. The ...
Synthesis, characterization and antimicrobial activity of novel 3-ferrocenyl-2-pyrazolyl-1,3-thiazolidin-4-ones
(Polyhedron, 2018-11)
A new series of ferrocene-containing thiazolylpyrazoles – 3-ferrocenyl-2-pyrazolyl-1,3-thiazolidin-4-ones have been synthesized using convenient one-pot three component condensation. Twelve newly synthesized compounds were ...
Synthesis of novel ferrocene-containing 1,3-thiazinan-2-imines: One-pot reaction promoted by ultrasound irradiation
(Tetrahedron Letters, 2018-09)
A simple one-pot synthesis of new ferrocene-containing 1,3-thiazinan-2-imines from 3-arylamino-1-ferrocenylpropan-1-ols and phenyl isothiocyanate has been developed. The key intermediate β-hydroxy thioureas were generated ...
The Non-Linear Regression - the Levenberg- Marquardt Algorithm for Assumption the Energy Losses of Hydraulic Transport in a Case of the Mine Trepca
(Thermal Science, 2019)
The main problem of hydraulic transport is the resistance generated during the mixture transport through the pipe-line. Testing the flow characteristics of mixtures, shown in this paper, are based on the principles of ...
Synthesis and Electrochemical Estimation of DNA-Binding Capacity of Novel Ferrocene-Containing Pyrrolidines
(The Electrochemical Society, 2020-01)
The design, synthesis, spectral and electrochemical characterization of a series of novel pyrrolidine derivatives have been described. The synthesis was achieved by 1,3-dipolar cycloaddition of azomethine ylides and ...
The proof of the Perepechko’s conjecture concerning near-perfect matchings on Cm x Pn cylinders of odd order
(Applicable Analysis and Discrete Mathematics, 2019-01)
For all odd values of m, we prove that the sequence of the numbers of near-perfect matchings on Cm x P2n+1 cylinder with a vacancy on the boundary obeys the same recurrence relation as the sequence of the numbers of perfect ...
Assessment of electronic system for e-patent application and economic growth prediction
(Physica A: Statistical Mechanics and its Applications, 2019-04)
Information system development is a complex endeavor, one which is fraught with peril if one do not follow a proven method. The Rational Unified Process (RUP) is one such method which could help to organize the development ...
Multivariate and multi-scale generator based on non-parametric stochastic algorithms
(Journal of Hydroinformatics, 2019)
A method for generating combined multivariate time series at multiple locations and at different time scales is presented. The procedure is based on three steps: first, the Monte Carlo method generation of data with ...
E-learning engineers based on constructive and multidisciplinary approach
(Computer Applications in Engineering Education, 2019-09)
In this study, we applied constructive approach to education supplemented with the innovation cycle approach. The main goal is to develop the innovative ideas from a clear start up to the implementation phase. Since multiple ...
Design of IIR Multiple-Notch Filters with Symmetric Magnitude Responses About Notch Frequencies
(Circuits, Systems, and Signal Processing, 2018-05)
A novel all-pass-based infinite impulse response (IIR) digital multiple-notch filter design method is presented in this paper. The proposed method ensures that, for an arbitrary pass-bands ripple value, specifications ...
