Earth Dynamics

An ideal definition of a reference coordinate system should meet the following general requirements:1. It should be as conceptually simple as possible, so its philosophy is well understood by the users.2. It should imply as few physical assumptions as possible. Wherever they are necessary, such assumptions should be of a very general character and, in particular, they should not be dependent upon astronomical and geophysical detailed theories.3. It should suggest a materialization that is dynamically stable and is accessible to observations with the required accuracy.

The focus of discussion in Working Group 3 was on the Thermodynamic Properties as determined spectroscopically, including the observational techniques and the theoretical modeling of physical processes responsible for the emission spectrum. Recent advances in observational techniques and theoretical concepts make this discussion particularly timely. It is wise to remember that the determination of thermodynamic parameters is not an end in itself and that these are interesting chiefly for what they can tell us about the energetics and mass transport in prominences.

La légionellose, un problème de tourisme? La légionellose est une maladie assez rare, mais elle suit souvent un cours prolongé et compliqué, même chez des patients immunocompétents. Le diagnostic est important pour des raisons thérapeutiques et épidémiologiques. De 1998 à 2001 on a observé à l'hôpital cantonal de Coire six cas de légionellose, dont quatre étaient associés aux voyages et un autre concernait un employé d'un hôtel local. Par suite de l'augmentation de la mobilité internationale les recherches épidémiologiques sur la localisation de la source infectieuse et les procédés hygiéniques deviennent plus difficiles. Une organisation européenne, le «European Working Group for Legionella Infections» (EWGLI/www.ewgli.org) a étudié ce problème. La question de la forme sous laquelle le public doit être informé des sources de légionelles fait l'object d'une discussion.
