Kinetic and theoretical study on nucleofugality in the phenolysis of 3-nitrophenyl and 4-nitrophenyl 4-cyanophenyl thionocarbonates
(Elsevier, 2013)
The phenolysis of 3-nitrophenyl 4-cyanophenyl thionocarbonate (1) and 4-nitrophenyl 4-cyanophenyl thionocarbonate (2) are subjected to a kinetic investigation in order to evaluate the nucleofugality of the corresponding ...
Theoretical study of solvent effects in the 1,3 rearrangement in the allyl–fluoride system in polar media
(1989)
The influence of electrostatic solvent effects on the barrier for the internal return rearrangement in the allyl–fluoride model system has been analyzed. The solvent was modeled through the self‐consistent reaction field ...

Aurophilic attraction in binuclear complexes with Au(i) and Au(iii). A theoretical study
(2004)
Model compounds are used to study the aurophilic attraction among gold atoms in the different oxidation states Au(i)-Au(i), Au(i)-Au(iii) and Au(iii)-Au(iii). An attraction is found for all models and there is a reasonable ...
Towards a theoretical approach to national systems of innovation
(Universidad de Chile. Facultad de Economía y Negocios, 1995-12)
The purpose of this paper is to formulate a theoretical framework as an alternative to the neoclassical one in order to find a more consistent explanation to the phenomenon of innovation and the process of growth. This new ...
Learning Activity as a Means of Developing Theoretical Thinking Capacities
(2020-12-14)
The main purpose of this article is to discuss the development of capacities linked to theoretical thinking during the formation process of Learning Activity in students of the early years of elementary school. It considers ...
Theoretical model and experimental analysis of glulam beam reinforced with FRP
(2006-12-01)
This work present a study of glulam beams reinforced with FRP. It was developed a theoretical model that calculates strength and stiffness of the beams. The model allows for the calculation of the bending moment, the ...
Meta-Theoretical Contributions to the Constitution of a Model-Based Didactics of Science
(Springer, 2016-07)
There is nowadays consensus in the community of didactics of science (i.e. science education understood as an academic discipline) regarding the need to include the philosophy of science in didactical research, science ...
