(Wiley, 2024)This study reports a rapid and efficient synthesis of four novel aryl Schiff base derivatives. Biological activity and molecular modeling studies were conducted to evaluate the inhibitory effects of these compounds on human ... -
The impact of the limit q-durrmeyer operator on continuous functions
(Springer, 2024)The limit q-Durrmeyer operator, D-infinity,D-q, was introduced and its approximation properties were investigated by Gupta (Appl. Math. Comput. 197(1):172-178, 2008) during a study of q-analogues for the Bernstein-Durrmeyer ... -
Anisotropic local structure of SrFe2-xNixAs2 (x=0.00, 0.16, and 0.23) superconductor probed by polarized X-ray absorption fine structure measurements
(MDPI, 2024)We have investigated the effect of the Ni substitution on the local structure and the valence electronic states of the SrFe2-xNixAs2 (x = 0.00, 0.16, and 0.23) superconductor with a multi-edge extended X-ray absorption ... -
Analysis of codon usage bias of exonuclease genes in invertebrate iridescent viruses
(Elsevier, 2024)Invertebrate iridescent viruses (IIVs) are double-stranded DNA viruses that belong to the Iridoviridae family. IIVs result diseases that vary in severity from subclinical to lethal in invertebrate hosts. Codon usage bias ... -
A facile ultrasonic synthesis approach to 3-H-quinazolinethione derivatives and their urease inhibition studies
