The examination of grazing incidence reflectivity data of X-rays shows a relatively simple empirical relationship between reflectivity, angle of reflection and wavelength, which is valid over more than 2 orders of magnitude of these parameters. It is demonstrated that the reflectivity does not depend on the atomic number, or other constants of the reflector, but depends only on the number of electrons participating in the reflection event. In the neighbourhood of the absorption edges a dispersion effect is shown to exist.

The study aims to report on the functioning and evolution of a few topicalisation markers (about/on. ), focusing in particular on the phenomena of gain/loss of autonomy, which vary according to the level of analysis at which: the internal structure of the expression or its functioning vis-à-vis the rest of the statement. In this respect, it will be interesting to compare the functioning of these expressions and the elements they introduce with that of detached buildings of different types on the left: "Paul, he doesn't telephone"/"Paris, carnival was a success this year". ; International audience ; The study aims to report on the functioning and evolution of a few topicalisation markers (about/on. ), focusing in particular on the phenomena of gain/loss of autonomy, which vary according to the level of analysis at which: the internal structure of the expression or its functioning vis-à-vis the rest of the statement.

Il sera à cet égard intéressant de comparer le fonctionnement de ces expressions et des éléments qu'elles introduisent avec celui des constructions détachées à gauche de différents types : « Paul, il n'a toutjours pas téléphoné » / « Paris, le carnaval a été une réussite cette année ».
