Abstract: A platform for a computer network for managing and sharing mostly unstructured data passing through said network, and having an infrastructure including an information system having a database and/or data servers, as well as terminals from which the users generate, modify or consult data of the information system, where the information system includes unique data to be shared and is insulated from the terminals of the users by an application that manages the accessibility to said information system and/or the security of the unique data contained by the same by a physical disconnection of the network protocol used for communication between the information system and the terminals of the users.

Abstract: A device for guiding pivoting of variable-pitch vanes in a turbomachine, each vane having a pivot formed by a cylindrical axial shank which is guided in a cylindrical chimney of the casing and in a cylindrical orifice of a stationary element which surrounds the outside of the casing and which is centered and fixed relative thereto. The invention improves pivotal guidance of variable-pitch vanes.
