The perihelion advance of the orbit of Mercury has long been one of the observational cornerstones for testing General Relativity (G.R.). The main goal of this paper is to discuss how, presently, observational and theoretical constraints may challeng

Despite its great importance for solar physics, mainly in the fields of solar fundamental astrometry, helioseismology, planetary motions and relativistic effects, the successive zonal harmonics of the Sun still remain elusive and subject to some cont

The main objectives of the space mission Picard, currently scheduled for the end of 2003 and under construction, are to measure simultaneously the solar diameter, differential rotation and its total irradiance (and according to the choice of the orbi

We use Singular Spectrum Analysis (SSA) to analyze total solar irradiance variations and CERGA radius measurements. Total solar irradiance has been monitored from space for more than two decades, whilst ground-based radius measurements are available

The modeling of the quadrupole moment J 2 and of the oblateness e, two key solar parameters, derives from the development in successive spherical harmonics of the gravitational potential. These harmonics are representative of the shape of the Sun, by

In this paper we first emphasize why it is important to know the successive zonal harmonics of the Sun's figure with high accuracy: mainly fundamental astrometry, helioseismology, planetary motions and relativistic effects. Then we briefly comment wh

The solar limb is potentially a sharp spatial reference with which we can detect the effects of solar oscillations (both pression and gravitation modes), the quadrupole moment -and higher moments if any-, the true shape of the helioid (the oblateness

Cases of Mycoplasma hominis infections after allograft are rare. We report a case of M. hominis wound infection after a vascular allograft. The allograft was positive before having any contact with the recipient, and our investigation suggests that M

En chirurgie non cardiaque, une elevation de la troponine est associee a une augmentation de la morbi-mortalite d'origine cardio-vasculaire a court et a long terme. La mortalite d'origine cardiaque est proportionnelle au pic du biomarqueur. L'IRM car
