Stability of gold nanowires at large Au - Au separations

The unusual structural stability of gold nanowires at large separations of gold atoms is explained from first-principles quantum mechanical calculations. We show that undetected light atoms, in particular hydrogen, stabilize the experimentally observed structures, which would be unstable in pure gold wires. The enhanced cohesion is due to the partial charge transfer from gold to the light atoms...

Extending DUNE: The dune-xt modules

We present our effort to extend and complement the core modules of the Distributed and Unified Numerics Environment DUNE (http://dune-project.org) by a well tested and structured collection of utilities and concepts. We describe key elements of our four modules dune-xt-common, dune-xt-grid, dune-xt-la and dune-xt-functions, which aim at further enabling the programming of generic algorithms wit...

Analyse critique de l’évolution du rôle de l’infirmière praticienne au Canada

Cet article propose une analyse critique de l’évolution du rôle de l’infirmière praticienne (IP) au Canada, en prenant pour exemple la province de l’Ontario. Il repose sur deux modèles théoriques choisis dans le but de mettre en évidence son développement historique et de dégager des pistes pour l’avenir. L’évolution du rôle d’IP comporte deux stades essentiels : le lancement et l’interruption ...

Modelling a Dune Field

We present a model to describe the collective motion of barchan dunes in a field. Our model is able to reproduce the observation that a typical dune stays confined within a stripe. We also obtain some of the pattern structures which ressemble those observed from aerial photos which we do analyse and compare with the specific field of Laâyounne.
