Absolute resonance strengths in the 6,7Li(alpha,gamma)10,11B reactions
The absolute strengths of the Ea=1175keV resonance in the 6Li(a,g)10B
reaction and of the Ea=814 keV resonance in the 7Li(a,g)11B reaction have been
measured to =366+-38 meV and =300+-32 meV,
respectively, in good agreement with previous values.
These resonances can be used to measure the absolute acceptance of the recoil
separator ERNA to a precision of about 10%.Comment: 6 pages, 5 figures, to appear in European Physical Journal

Grand Canonical Adaptive Resolution Simulation for Molecules with Electrons: A Theoretical Framework based on Physical Consistency
A theoretical scheme for the treatment of an open molecular system with
electrons and nuclei is proposed. The idea is based on the Grand Canonical
description of a quantum region embedded in a classical reservoir of molecules.
Electronic properties of the quantum region are calculated at constant
electronic chemical potential equal to that of the corresponding (large) bulk
system treated at full quantum level. Instead, the exchange of molecules
between the quantum region and the classical environment occurs at the chemical
potential of the macroscopic thermodynamic conditions. T he Grand Canonical
Adaptive Resolution Scheme is proposed for the treatment of the classical
environment; such an approach can treat the exchange of molecules according to
first principles of statistical mechanics and thermodynamic. The overall scheme
is build on the basis of physical consistency, with the corresponding
definition of numerical criteria of control of the approximations implied by
the coupling. Given the wide range of expertise required, this work has the
intention of providing guiding principles for the construction of a well
founded computational protocol for actual multiscale simulations from the
electronic to the mesoscopic scale.Comment: Computer Physics Communications (2017), in pres

Algunas relaciones entre investigación, práctica pedagógica y formación inicial: relatos de una experiencia
Desde la perspectiva del Proyecto Curricular de Licenciatura en Biología (PCLB), la Investigación se convierte en un elemento de vital importancia en la formación inicial de profesores de Biología, desde una mirada crítica y transformadora que repercute en el diseño y ejecución de los “Proyectos de práctica pedagógica” y posteriormente en los Trabajos de Grado
Learning Entrepreneurship with Serious Games - A Classroom Approach
The use of educational games for pedagogical practice can provide new
conceptions of teaching-learning in an interactive environment stimulating the
acquisition of new knowledge. The so-called serious games are focused on the
goal of transmitting educational content or training to the user. In the
context of entrepreneurship, serious games appear to have greater importance
due to the multidisciplinary of the knowledge needed. Therefore, we propose the
adoption of the Entrexplorer game in the context of a university classroom. The
game is a cloud-based serious game about the theme of entrepreneurship where
users can access learning contents that will assist them in the acquisition of
entrepreneurial skills. The organization of the game in eight levels with six
additional floors let students learn the different dimensions of an
entrepreneurship project while progressing during the gameplay.Comment: 6 page
