Elimination of quantifiers of a theory of real closed rings.
(2022-10-09)
Let T* be the theory of lattice-ordered subrings, without minimal (non zero) idempontents, convex in von Neumann regular real closed rings that are divisible-proyectable and sc-regular. In this paper, a local divisibility ...
Spectral and kinetic properties of radicals derived from oxidation of quinoxalin-2-one and its methyl derivative
(MDPI AG, 2014)
© 2014 by the authors licensee MDPI Basel Switzerland.The kinetics and spectral characteristics of the transients formed in the reactions of • OH and •N3 with quinoxalin-2(1H)-one (Q), its methyl derivative, 3-methylquinoxalin- ...
On skew braces
(EMS Publishing House, 2018-02)
Braces are generalizations of radical rings, introduced by Rump to study involutive non-degenerate set-theoretical solutions of the Yang-Baxter equation (YBE). Skew braces were also recently introduced as a tool to study ...
Electrochemical approach to the radical anion formation from 2′-hydroxy chalcone derivatives
(2006)
Three 2′-hydroxy chalcone derivatives were electrochemically reduced to the radical anion by a reversible one-electron transfer followed by a chemical dimerization reaction. Under suitable conditions of the medium, the ...
Combinatorial solutions to the reflection equation
(Academic Press Inc Elsevier Science, 2020-05)
We use ring-theoretic methods and methods from the theory of skew braces to produce set-theoretic solutions to the reflection equation. We also use set-theoretic solutions to construct solutions of the parameter dependent ...
Rate constant of the reaction between CH3O2 and OH radicals
(Elsevier Science, 2013-12)
The rate constant of the reaction (R1)OH+CH3O2→products has been measured at 294 K by simultaneous coupling of Laser Induced Fluorescence (LIF) and cw-Cavity Ring Down Spectroscopy (cw-CDRS) to laser photolysis. OH ...
Local divisibility and model completeness of a theory of real closed rings
(2021-01)
Let T∗ be the theory of lattice-ordered rings convex in von Neumann regular real closed f-rings, without minimal idempotents (non zero) that are divisible-projectable and sc-regular. I introduce a binary relation describing ...
Polymer cosolvent system
(1985)
Both preferential adsorption coefficient ? and intrinsic viscosity [?] for poly (di-o-alkylphenyl methacrylates) /Tetrahydrofuran (THF)/water have been determined. The results are discussed in relation to the steric effect ...
