... the UAB [University of Alabama at Birmingham] team probed deeper into the welding process and made a fundamental metallurgical discovery-constitutional liquid film migration-a phenomenon that Dr. Thompson says would not have been found without the Gleeble. In the 1980's, researchers working in solid state electronic devices discovered diffusion-induced grain boundary migration, in which diffusion of elements from the top layer of a device would cause the grain boundaries to move in unpredictable directions. Five years later, other investigators found that running a liquid along the grain boundary could also cause it to move. Then, in the course of their NASA-related research, Dr. Thompson and his colleagues discovered that liquid film migration of grain boundaries occurred naturally during welding as the result of precipitates liquating in the heat affected zone. The UAB team further found that the migration distance was an order of magnitude greater than previously observed and that new grains were actually formed during the process. Spurred on by this discovery, the UAB researchers looked at real-world welding processes and found that constitutional liquid film migration could be found there too.  1, record 1, English, - liquid%20film%20migration%20of%20grain%20boundaries

The Advanced Camera for Surveys(ACS) was installed in the Hubble Space Telescope(HST) during Servicing Mission 3B, launched aboard the Space Shuttle Columbia(STS-109) 1 March 2002 6 : 22 am EST. The ACS increases the discovery efficiency of the HST by a factor of ten. It consists of three electronic cameras and a complement of filters and dispersers that detect light from the ultraviolet to the near infrared(1200-10, 000 angstroms).  2, record 2, English, - advanced%20camera%20for%20surveys

De nouveaux instruments ultra sophistiqués vont donner une nouvelle jeunesse à l'observatoire. Le télescope va par exemple être équipé d'une nouvelle caméra numérique, la caméra de technologie avancée pour observations panoramiques (ACS), qui pourra réaliser des images du ciel deux fois plus grandes avec une sensibilité cinq fois supérieure à celle des instruments précédents, ce qui multipliera donc par dix les capacités d'observation du télescope!  2, record 2, French, - cam%C3%A9ra%20de%20technologie%20avanc%C3%A9e%20pour%20observations%20panoramiques

The speed of virus spread is much slower than most people expect. This means that the logging of occurrences is important, even with a significant margin of error in reporting the time of discovery. Place of discovery is more difficult to get wrong and can also be used in plotting the progress of the spread of a virus. Electronic communications are making the plotting of the virus spread more difficult, since a user can contract a virus from a program downloaded from bulletin boards one mile away or 10, 000 miles away equally easily.  1, record 3, English, - virus%20spread

La vitesse de propagation d'un virus est beaucoup plus lente qu'on ne le pense généralement. Il est donc important d'enregistrer les occurrences même avec une marge d'erreur significative dans la signalisation de l'heure de la découverte. Le lieu de la découverte est plus facile à déterminer et permet également de suivre la propagation du virus.  1, record 3, French, - propagation%20du%20virus
