(Universidade Federal de Minas GeraisUFMG, 2014-04-14)
In Chapter 1, begins the study of algebraic equations, more specifically of cubic equations. The chapter begins with a brief historical introduction which illustrates the challenges faced by mathematicians to reach a ...
Caracterización estructural, espectroscópica y termoquímica del C2CL4 de interés medioambientalStructural, spectroscopic and thermochemical characterization of C2CL4 of environmental concern
(Universidad Nacional de Asunción. Facultad de Ciencias Exactas y Naturales, 2015-12)
El desarrollo del sector industrial en Paraguay es relativamente reciente, por lo tanto actualmente no existe una problemática medioambiental pronunciada. No obstante, la amplia aplicación del tetracloroetileno, C2 Cl4, ...
Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.
(Taylor & Francis Ltd, 2009-12)
The singlet oxygen (1O2) quenching and free radical (DPPH+, ABTS and O2 +) scavenging ability of three structurallyrelated flavonoids (7-hydroxyflavanone HF, 2´,4´-dihydroxychalcone DHC and 3,7-dihydroxyflavone DHF) present ...
Mechanistic insights into the reaction between VO2+ and propene based on a DFT study
(Amer Chemical Soc, 2006-03-27)
Calculations based on density functional theory have been carried out to investigate the free energy profiles at singlet and triplet electronic states associated with the gas-phase ion/molecule reactions of VO2++ ((1)A(1)/(3)A) ...
