S’il y a une chose que notre société doit retenir de la pandémie Covid-19, c’est l’impérieuse nécessité, pour les personnes âgées plus particulièrement, maintenir du lien physique. C’est le message Vincent Rebeille, médecin généraliste exerçant depuis trente-sept ans en quartier prioritaire1. À travers...

L’expérience de la pandémie, notamment l’épisode du confinement printemps 2020 et l’état d’urgence sanitaire, rend plus visible, parmi des questionnements qui lui préexistaient, mais dont l’opinion publique voire les chercheurs n’avaient pas tellement pris mesure l’urgence ou l’importance, les questions suivantes&#160...

Reflectivity synthetic seismograms demonstrate that the type, layering and orientation of 1-D anisotropy influences strongly the coda of teleseismic P waves at periods T\1 sec, particularly P-SH converted waves. We assume the simplest form of anisotropy described by an elastic tensor with a symmetry axis ŵ of arbitrary orientation. The resulting phase velocities vary as cos 2j with respect to t...

The coupling between seismic and electromagnetic waves in a fluid-saturated porous medium is essentially controlled by the electrokinetic effect. The inverse effect of the seismoelectric conversion, the electroseismic conversion, is investigated experimentally in the laboratory. The electric field induces movement of the ions in a pore fluid relative to the solid matrix. The interaction between...

We present a comprehensive set of stellar evolution models for Procyon A in an effort to guide future measurements of both traditional stellar parameters and seismic frequencies towards constraining the amount of core overshoot in Procyon A and possibly other stars. Current observational measurements of Procyon A when combined with traditional stellar modeling only place a large upper limit on ...
