« La pourriture grise s'est manifestée de tous temps, d'une façon plus ou moins grave, dans le vignoble français ; mais c'est surtout depuis une vingtaine d'années, depuis que le vignoble a été reconstitué par la voie du greffage, que ses rav

Le Botrytis cinerea est devenu actuellement, dans certaines régions viticoles au moins, le parasite le plus redoutable de la vigne. De nombreux travaux ont déjà été consacrés à ce champignon, mais de nouvelles recherches s'avèrent indispensab

Free-Space Laser Communications XXXIII.
We present the status of ongoing work at NASA-Goddard Space Flight Center (GSFC) to build a low-cost flexible ground terminal for optical communication. Previous laser communication missions at NASA have been supported by one-of-akind ground terminal

The use of epoxies in space-based instruments is often unavoidable in situations where the bonding of dissimilar materials such as glass and metal is required. While there are epoxies that exhibit low total mass loss (TML) and collected volatile cond

Free-Space Laser Communications XXXI.
Photonic lanterns provide an efficient way of coupling light from a single large-core fiber to multiple small-core fibers. This capability is of interest for space to ground communication applications. In these applications, the optical ground receiv

Free-Space Laser Communication and Atmospheric Propagation XXX.
Fiber amplifiers have been used in many laser communication applications due to their compactness and high efficiency. However, fiber amplifiers for free space laser communications have been limited to low peak power communication formats due to nonl
NASA is planning to launch the next generation of a space-based Earth relay satellite sometime in the middle of the next decade to join the current Space Network, consisting of Tracking and Data Relay Satellites in space and the corresponding infrast
