摘要:
The present invention relates to a flexible sealing membrane that is particularly useful for covering roofs. The flexible sealing membrane is usable for sealing substantially planar surfaces such as roofs or the like, said membrane being essentially water- and steam-tight, characterized in that said membrane does not contain any bitumen or bitumen derivative and also characterized in that said membrane is essentially formed of at least one thermoplastic (co)polyurethane or thermoplastic (co)polyamide, thus ensuring the essentials of said sealing functions, said thermoplastic (co)polyurethane(s) or thermoplastic (co)polyamide(s) each containing at least one natural monomer that is integrated into the (co)polymer during the polymerization(s) thereof.
摘要:
The invention relates to a novel discriminating molecule family for neutron and gamma radiation and to the preparation method thereof. Said molecules are also useful for detecting radiation (X, gamma, electrons, protons, ions), and thus for manufacturing radar and industrial or medical dosimetry instruments.

摘要:
The invention relates to a chemical reactor having a nanometric structure and including at least one member in which is formed at least one reaction chamber, said chamber being at least partially filled with a high specific-surface material having a specific surface higher than 5 m 2 /g, characterised in that said high specific-surface material is selected from nanotubes or nanofibres. The nanotubes or nanofibres are preferably selected in the group comprising β-SiC nanotubes or nanofibres and TiO 2 nanotubes or nanofibres. They can be deposited on an intermediate structure selected in the group comprising glass fibres, carbon fibres, SiC foams, carbon foams, cellular β-SiC foams, said intermediate structure at least partially filling the reaction chamber of the reactor.

摘要:
The invention relates to at least one marking reagent of the formula (1) in which: R1 is at least one detectable marker; L and A are each a bonding arm; n is an integer equal to 1; and u is an integer between 0 and 2. The invention also relates to a method for the synthesis of said markers and to applications for marking biological cells, in particular nucleic acids, with a marking reagent bearing diazo and nitro functions. The invention can preferably be used in the field of diagnosis.
摘要:
The invention relates to a flexible endoscope device comprising an elongated flexible body having an end segment bearing or defining the endoscope head, and provided with an optical system and that can be curved or bent in at least two mutually perpendicular directions, said elongated body being functionally connected at the other end thereof to a control means capable of controlling at least the movements and/or the arrangement of said end segment. The device (1) is characterised in that it further comprises automatic flexion and positioning means of the end segment (3) by visual control, said means essentially comprising a video processing means (6) for receiving the images or video signals provided by the optical system (4) of the endoscope head (3') using a computer means (7) capable of carrying out visual control operations on the basis of the processed video signals and of transmitting control signals, and actuation means (8, 8') that are part of or associated with the control means (6) capable of controlling the end segment (3) and receiving the control signals supplied by the computer means (7).
