Abstract: An audio-visual live content delivery system includes a client having access to a provider network via a gateway, an audio-visual live content delivering equipment comprising a multicaster for transmitting audio-visual live contents in multicast form via the provider network, a de-multicaster being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster, and a controller managing routing of requests to get audio-visual live contents. The client performs a discovery procedure aiming at receiving information on potential presence and availability of the de-multicaster. When the client intends receiving a targeted audio-visual live content, the client sends to the controller a request providing indication of presence and availability, or not, of the de-multicaster. Then the controller decides how redirecting the client to fulfill the request, according at least to the indication of presence and availability, or not, of the de-multicaster.

Abstract: Method for thermally treating a scrolling steel strip (5), said method comprising the following steps: heating the strip (5) in a zone for heating with a direct flame (10); temperature homogenisation of the strip (5) in a homogenisation chamber (20) comprising at least one radiant heating tube (25), so as to homogenise the strip (5) in temperature after the passing thereof into the zone for heating with a direct flame (10) of the preceding step; oxidation of the strip (5) in an oxidation chamber (30) with an oxidising atmosphere having an oxygen volume concentration greater than 1%; reduction of the strip (5) in a reduction zone (40).

Abstract: A universal decontamination formulation is disclosed based on the in situ generation dioxirane(s) under non-corrosive neutral conditions for the neutralization of chemical and biological warfare (CBW) agents. The composition relates to the generation of dioxiranes by mixing a monopersulfate-containing compound in the presence of a ketone in water buffered with a carbonate-type buffer, producing a pH neutral formulation that provides effective reactivity towards CBW agents over a wide range of temperatures.

Abstract: A system and method facilitates reliance among members of a community that communicates electronically. Each member has a private credential for use in a computing environment. Each member obtains the credential in accordance with a credential-issuance process. The process need not include a certification authority. Credentials may be generated directly by the members themselves. They system includes a database that contains at least one credential entry for each member . The system also includes a management process with authority to sanction (e.g., approve) reliance by the community on a member's credential. Such sanction authority is separate from the credential-issuance process. The system also includes a rule set defining a scope of reliance the community may make on a member's credential.

Abstract: This bath reboiler-condenser (4), of the brazed plate type, includes vaporization passages (11) subdivided into a plurality of stacked vaporization regions (13A to 13C) each of which is immersed in a partial height bath (28A to 28C), and means for feeding the top vaporization region (13C) with liquid. The vaporization regions (13A to 13C) are spaced vertically and each region is entirely open at its top and bottom ends. Application to the main reboiler-condensers of double air distillation columns.

Abstract: A wafer of indium phosphide is disposed between two electrodes (102, 104) in a heated enclosure (100) into which ducts (110 and 112) admit nitrogen and ammonia. A high frequency electricity generator (108) forms a plasma between the electrodes which etches the exposed surface of the wafer. The invention is applicable, in particular, to forming semiconductor lasers emitting in the infrared for telecommunications purposes.
