French transportable laser ranging station: scientific objectives, technical features, and performance.

The French Transportable Laser Ranging Station (FTLRS) is a highly mobile satellite laser ranging (SLR) system unit that weighs 300 kg and is housed in eight containers. This telemetry laser station is dedicated to the tracking of geodetic satellites equipped with retroreflectors. There are fascinating uses in the geosciences for such a system: in tectonics, oceanography, terrestrial reference frames, and precise positioning.

[Generalized adenomyomatosis of the gallbladder: ultrasonographic appearance in one case (author's transl)].

Ultrasonographic images were correlated with radiological and pathological findings in a case of generalized adenomyomatosis of the gallbladder. Emphasis is placed on the importance of the methods employed for filling the biliary tracts with opaque medium, to confirm a suspected diagnosis suggested by the heterogeneous irregular thickening, with a fringed internal limit, of the gallbladder wall.
