Abstract: Some embodiments provide tools that allow a user to share content on one device with multiple other users using different devices. The content sharing tools allow the user to (1) create a shared stream that represents a set of shared content and (2) invite one or more recipients to subscribe to the shared stream. When a recipient subscribes to the shared stream, the set of content is streamed across one or more of his or her devices. In some embodiments, the content sharing tools are integrated into an operating system of a device.

Abstract: The invention concerns a cost-reduction method per action performed during an online interactive advertising campaign. The method implements the following steps: the cost of each keyword in the campaign is revalued (12), positive keywords are generated (16), negative keywords are generated (17), automatic performance tests (20) of the advertising campaign are conducted, the best messages (19) of the campaign are generated, the advertising campaign is sent to the Search Engine Media.

Abstract: A hexagonal ring structure whose internal contour conforms to the external contour of the reactor core rests on the periphery of the reactor diagrid and is constituted by a plurality of layers of metallic plates. The layers are maintained in relative positional relation by means of clamping members, the plates of one layer being angularly displaced with respect to the plates of adjacent layers. The bottom end-connectors of the elements constituting the lateral shield system are fitted in vertical through-holes formed in the ring structure.

Abstract: The upper portion of a hollow cylindrical spacer column is rigidly fixed to the reactor diagrid and supports a fuel assembly end-fitting by means of a removable sleeve having a conical bearing surface for sealing and centering the fuel assembly. The sleeve is engaged in interfitting relation with the column head and secured thereto by means of a removable annular weld connection.

Abstract: A self-propelled carriage for inspecting the primary vessel of a fast reactor is capable of displacement within the interspace between the primary vessel and the containment vessel in order to inspect and test any predetermined zone of the primary vessel, the carriage being associated with a drive mechanism and applied against the oppositely-facing wall of the containment vessel. The carriage is suspended from a composite cable actuated by a handling apparatus for introducing the carriage into the interspace and withdrawing it therefrom. The composite cable supplies electric power as well as the different fluids required for positioning and operation of the inspection devices which are mounted on the carriage.
