If you are not a Mac user, or if you are not interested in any of the following topics: X ray microscopy, X ray tomography, X ray microcinematography, 3D reconstruction, diffusion processes in solid and/or liquids, then discard this message: lassi.sea.hqx is NOT for you. BUT, if you are still reading this message, then you may download on your mac (BINARY mode) the file named "Lassi.sea.bin" which is on zippy.nimh.nih.gov in the folder pub/image/contrib. After self-extracting the data, you should get a folder "LASSI-DEMO" which contains a file READ.ME giving instructions on how to see an animated (including quicktime movies) presentation of the main aspects of the research of Pr. Jacques CAZAUX's lab (LASSI means Laboratory for Analysis of Solids, Surfaces and Interfaces) located in Reims (France). Acknowledgments must be given to Wayne, the creator of the NIH-Image program which has been (and is still) extensively used by our lab. Enjoy the show and next time you drink a bottle of Champagne, remember Reims! Pierre Trebbia (e-mail: pierre.trebbia@univ-reims.fr)
