Abstract: The present invention relates to a method for stimulating the resistance of plants to biotic stress by radiation exposure of at least one spot of a plant characterized in that the radiation exposure is performed by UV-C rays alone or UV-B rays alone or a combination thereof with an exposure duration being less or equal to one second and the radiation exposure being repeated at least once with an interval of time between one hour and one month. The invention will find an application for stimulating natural defenses of plants to biotic stress as pests, bacteria, fungus or virus. The invention could be used directly on plants growing in fields for agriculture and the food industry.

Abstract: An attenuation device for attenuating sound waves, and a corresponding system and method, generated by a source emitting sound waves having frequencies between f1 and f2 and wherein the pressure levels are between n1 and n2. The attenuation device comprising at least one acoustic absorber comprising at least one non-linear membrane; the attenuation device being configured in such a way that the first face of the absorber is in acoustic communication with the source. The attenuation device also comprises at least one coupling element for coupling the second face with the source, the coupling element being configured to transmit to the second face sound waves according to the sound waves emitted by the source, and of which the phase and/or the amplitude leads to a pressure differential of the sound waves arriving respectively on the first and second face at the same time.

Abstract: A device for extraction of pollutants by multichannel tubular membrane containing at least one fluid channel allowing the fluid to go through a feed inlet to an outlet end characterized in that membrane comprises at least an extraction channel filled with molten salt in order to adsorb said pollutants having to be extracted from the said fluid. Advantageously, the membrane is a ceramic membrane. An application is for the treatment of traces of pollutants in a liquid or gaseous fluid. For example, the removal of small pollutants as volatile organic compounds from an aqueous stream in industrial wastewater treatment or other water treatment applications, or the separation of aromatic compounds form an hydrocarbon feed in petrochemical applications. Another application is in the removal of water traces in products of high added value as pharmaceutical, cosmetic or biocarburant for example.

Abstract: The invention relates to a novel use of compounds having formula (I), including mifepristone (RU 486 or RU 38 486) and the derivative salts thereof, for the preparation of a medicament that can modulate(activate or inhibit) the Hedgehog protein signalling pathway, which is intended for the treatment of pathologies involving a tissue dysfunction linked to deregulation of said pathway.

Abstract: Modified recombinant protein derived from Streptococcus pneumoniae PBP2x, referred to as mini-PBP2x, consisting of a concatenation of the fragments corresponding, respectively, to the amino acids located between positions 74 to 90, 186 to 199, 218 to 228 and 257-750, with reference to the sequence of the PBP2x protein of the strain R6 (SWISSPROT P14677 or GENBANK 18266817), each one of said fragments being preceded by a peptide fragment of 1 to 7 amino acids, and uses of said mini-PBP2x protein for selecting and identifying antibiotics which are active on ?-lactam-resistant strains of S. pneumoniae.
