Abstract: The invention concerns a method for obtaining data related to data packets exchanged during at least one communication in a network (R) comprising a plurality of sub-networks (R1, R2, R3, R4, R5). The method is suitable for generating a request comprising a piece of time information and a terminal identifier and for obtaining a response comprising at least one dated dataset related to at least one data packet, said at least one set being selected by a second entity (S2) of at least one second sub-network (R2), from a plurality of datasets related to data packets received by at least one entity of said at least one second sub-network (R2), depending on the time information and the terminal identifier. The invention also relates to an entity (S1I) of a sub-network (R1) implementing the obtaining method.

Abstract: The present invention relates to a method for manufacturing hydrophilic biopolymers, particularly hydrophilic cellulosic material, particularly cellulose nanofibers like micro- or nanofibrillated cellulose, as described in claim 1; to novel materials comprising hydrophilic biopolymers and to the use of such hydrophilic biopolymers.

Abstract: A fibrous substrate material for producing a porous coating base paper or prepreg comprises a planar impregnatable structure made of cellulose fibers, which contains at least one pigment species and optionally contains further additives conventional for paper. The cellulose fibers contain a proportion of 1 to 20 wt.-% of nanofibrillated cellulose (NFC). A method for producing the fibrous substrate material comprises the steps of: providing an aqueous suspension containing a cellulose containing material and an admixture of said pigment species and, optionally, further additives conventional for paper, sheet forming, drying. The cellulose containing material contains a proportion of 1 to 20 wt.-% of NFC with a specific surface (SSA) of at least 125 m2/g.

Abstract: In a method for improving the acoustic properties of spruce resonance wood for musical instruments at least one resonance wood blank is subjected to a treatment with Physisporinus vitreus under controlled, sterile conditions. The previously sterilized resonance wood blank is immersed into a liquid medium enriched with fungus myecelium and kept therein in the dark for an exposure time and finally sterilized, wherein during the exposure time a temperature of 18 to 26° C. and a relative humidity of approximately 60 to approximately 80% are maintained. Due to the fact that the liquid medium contains nanofibrillated cellulose (NFC) in an amount of 200 to 300 g per liter, a reproducible, uniform improvement of the acoustic properties of the resonance wood free from local defects is ensured.

Abstract: The invention relates to a telecommunication system including a plurality of terminals divided into groups such that within each group each terminal can send multidestination messages to the other members of the group. Each terminal of a group is associated with encryption and decryption means so that each terminal can send multidestination messages that can be decrypted only by the other terminals of the group. The system includes a central server for distributing to each encryption and decryption means keys for secure transmission of communications within each group.

Abstract: The invention relates to a photocatalyst comprising a cellular foam selected from carbon foam and the foam of a carbon material, such as a polymer, and a photocatalytically active phase, deposited directly on said cellular foam or on an intermediate phase deposited on said cellular foam. The average size of the cells is between 2500 ?m and 5000 ?m. The foam can comprise nanotubes or nanofibers (in particular TiO2).

Abstract: A method in accordance with the invention applies to an access network or a satellite infrastructure network supporting sub-networks grouping different terminal stations in which each packet is associated with an addressing header and in which each terminal station is associated with a satellite terminal or with a ground station that is located in the coverage of a particular spot of a particular satellite. The addressing header of each packet further contains a “label” field containing an identifier characteristic of a sub-network to which said terminal station and the spot in which the satellite terminal or the ground station with which it is associated is located belongs.

Abstract: A system is dedicated to controlling processes associated with streams of application data for a communication network including communication stations adapted to exchange data streams and connected to communication terminals provided with at least one application and one core containing information representative of the applications. The system includes processing arrangements which, on receiving a message designating an application, deliver service data representative of at least one process associated with the designated application. The system also includes extraction arrangements which, on receiving a stream of data sent by a communication terminal, access the core of the terminal to determine the application associated with the received stream and then deliver to the processing means a message designating the determined application.
