Hacia una democracia mundial:

open access: yesRevista de Fomento Social, 2015
La expresión “autoridad mundial” fue usada por Juan XXIII en 1963 en su encíclica Pacem in terris, al servicio del bien común universal. Los grandes cambios en las relaciones internacionales exigen que para promover ese mismo bien común deba existir una

Quasiclassical frustration

open access: yes, 2005
We study the dissipative properties of a harmonic oscillator subject to two independent heat baths, one of which couples to its position and the other one to its momentum. This model describes a large spin impurity in a ferromagnet.

Realization of uniform synthetic magnetic fields by periodically shaking an optical square lattice [PDF]

open access: yes, 2016
Shaking a lattice system, by modulating the location of its sites periodically in time, is a powerful method to create effective magnetic fields in engineered quantum systems, such as cold gases trapped in optical lattices.

El pensamiento de Ignacio Ellacuría acerca de la función social de la universidad

open access: yesArbor: Ciencia, Pensamiento y Cultura, 2016
En un contexto histórico sorprendente, el de El Salvador (Centroamérica) de los años setenta y ochenta, con revueltas populares contra el sistema socioeconómico poscolonial, con una guerra civil que duró diez años, con asesinatos masivos de población ...

Characterization of Rod-like High-purity Fluorapatite Nanopowders Obtained by Sol-gel Method [PDF]

open access: yesJournal of Ultrafine Grained and Nanostructured Materials, 2013
high purity fluorapatite (FA) with rod-like and spherical-like morphology was synthesized via sol-gel method. Chemical characterization of FA powders was done by XRD and FTIR analyses. Crystallite samples were calculated using Scherer method.

Optimum sol viscosity for stable electrospinning of silica nanofibres [PDF]

open access: yes, 2013
Silica nanofibres have, due to their excellent properties, promising characteristics for multiple applications such as filtration, composites, catalysis, etc. Silica nanofibres can be obtained by combining electrospinning and the sol–gel process.

Del desarrollo integral del hombre a la ecología integral. Análisis comparativo de los conceptos de desarrollo integral del hombre (Populorum Progressio, Pablo VI, 1967) y de ecología integral (Laudato Si’, Francisco, 2015)

open access: yesRevista de Fomento Social, 2018
La teología ha ido incorporando a su acervo los diferentes retos a los que la humanidad se ha ido enfrentando a partir del magisterio pontificio y en los años sesenta el mundo se enfrentaba, entre otros, al tema del desarrollo.

Conductances in normal and normal-superconductor structures

open access: yes, 1999
We study theoretically electronic transport through a normal metal-- superconductor (NS) interface and show that more than one conductance may be defined, depending on the pair of chemical potentials whose difference one chooses to relate linearly to the

Layered Chaos in Mean-field and Quantum Many-body Dynamics [PDF]

open access: yes, 2019
We investigate the dimension of the phase space attractor of a quantum chaotic many-body ratchet in the mean-field limit. Specifically, we explore a driven Bose-Einstein condensate in three distinct dynamical regimes - Rabi oscillations, chaos, and self ...
