Abstract: The present invention relates to skin care compositions comprising one or more inorganic particulate materials selected from the group consisting of delaminated talc, delaminated bentonite, an alkaline earth metal carbonate or sulphate, such as calcium carbonate, magnesium carbonate, dolomite, gypsum, a hydrous kandite clay such as delaminated kaolin, halloysite or ball clay, an anhydrous or calcined kandite clay such as metakaolin or fully calcined kaolin, mica, perlite or diatomaceous earth, or magnesium hydroxide, or aluminium trihydrate, or combinations thereof; and/for wherein the inorganic particulate material has a BET surface area of least about 10.0 m2/g. The present invention further extends to the use of such compositions.

Abstract: Nanovectors are disclosed that make it possible to simultaneously target, image, and treat cancerous cells using photodynamic therapy. Also disclosed are novel molecules (I) derived from porphyrins, silica-based nanoparticles comprising the same, and their use in photodynamic therapy.

Abstract: This invention relates to porphyrin compounds used to destroy or impair the functioning of a target biological material in photodynamic therapy, in particular against virus, tumoral cells, bacteria, tumorous tissues. The invention also relates to compositions containing such compounds and to a method in vitro to photosensitize detroy or impair the functioning of such target biological material.

Abstract: A practice projectile includes a body formed from assembling a number of sectors. The sectors are made of plastic and designed to be received in a receptacle of a base. The body is held together during handling by a holder. The holder is designed to release the sectors once they exit the barrel of a weapon when the projectile is fired.

Abstract: A cooking vessel produced from a disc (3) of light alloy or metal includes a bottom (1) intended to be placed on a cooking plate, a burner or the like. The bottom (1) includes a plate (2) made of a metal having properties different from those of the metal of the disc (3). This plate (2) is completely or partially embedded in the bottom (1) and its periphery is preferably adjacent to a groove (4). The bottom of such a cooking vessel exhibits improved resistance to deformation.

Abstract: The chamfering device comprises a frame to be centered and fixed coaxially within the pipe. A tool and its support are mounted concentrically around the frame and are movable along and about the axis in both translation and rotation by drive motors, and its position is detected and fixed before chamfering. The entire operation proceeds automatically without visual control or manual action, so that it can be performed in a radioactive environment.

Abstract: Apparatus for replacing thermal sleeves in pressurized-water nuclear power station circuits in a rapid, automatic manner producing minimal debris. A two-part frame is fixed to the outer wall of the sleeve coaxially therewith, each part of the frame carried one part of a two-part rotatable element, which in turn carries a support for a cross-cutting tool. The tool support is moved toward the axis of the frame but stopped just before the too breaks into the interior space of the sleeve.

Abstract: Process of replacing a sleeve mounted within a pipe, and devices for carrying out that process. The process consists in making a pair of cross cuts in the pipe (1'), withdrawing the section thus obtained and the sleeve (5'), machining chamfers on the free ends of the pipe (1'), checking the position and the geometry of the blocks (6'), welding into the gap in the pipe (1') a new section, onto the internal wall of which one of the ends of a new sleeve (5') has previously been welded. The invention can be applied to the circuits of pressurized-water nuclear power stations.
