Abstract: A device for surface brachytherapy includes a base configured for positioning a source with respect to a target area, an aperture defined in the base, and a shield body configured for coupling with the base, so that the source is secured within the base proximate or adjacent the aperture. The aperture is configured to transmit radiation emitted by the source, where the radiation is directed toward the target area. The base and shield body are configured to absorb at least a portion of the radiation emitted by the source, where the radiation is not directed toward the target area.

Abstract: The manufacturing method makes it possible to manufacture a tire (10) comprising: a tread (14), an airtight internal layer (18), and at least one layer of a self-sealing product (80) extending circumferentially radially on the inside of part of the airtight internal layer (18). During the method, a strip or a bead (200) of a self-sealing product is wound through multiple circumferential turns (Nai, Nbj) radially on the inside of the airtight layer (18) of the tire, which does not have the layer of self-sealing product (80) yet, and at least partially in line with the tread (18). The winding step is carried out according to a law for winding the strip or the bead (200) in circumferential turns. During the winding step, at least one parameter of the winding law making it possible to axially vary the thickness of the layer of self-sealing product (80) is varied.

Abstract: The tire comprises a tread comprising a main circumferential cut (52, 54, 56, 58) and a rib (62, 64, 66, 68, 70), an airtight internal layer, and a layer of a self-sealing product (80) comprising: an axial portion extending in line with the main circumferential cut (52, 54, 56, 58) and having an average thickness Ea>0, and an axial portion extending in line with the rib (62, 64, 66, 68, 70) and having an average thickness Eb?0 of self-sealing product such that Eb<Ea.

Abstract: The tire comprises a tread (14) comprising a deeply cut rib (68, 70) and a slightly cut rib (62, 64, 66), and a layer of a self-sealing product (80) comprising: a portion (90?, 92?) extending in line with the deeply cut rib (68, 70) and having an average thickness Ec > 0 of self-sealing product, and a portion (100?, 102?, 104?) extending in line with the slightly cut rib (62, 64, 66) and having an average thickness Eb ? 0 of self-sealing product such that Eb <Ec.

Abstract: A tire having an adhesive sealant applied to the radial interior of the tire in the region of the belt reinforcements of the crown with a noise-dampening foam ring having circumferential grooves in the radial outside surface of the foam is applied to the adhesive sealant. The grooves of the foam are laterally aligned with the circumferential grooves of the tire such that the foam touches the sealant on areas that are not laterally aligned with the longitudinal grooves of the tire.

Abstract: A novel treatment method is disclosed, wherein a patch configured to be placed on a patient's skin is activated, before placement, to deliver localized radiotherapy to a diseased area of the skin. The disclosed devices and methods minimize or prevent collateral damage to the neighboring tissues. In most cases, the disclosed devices and methods include coating a contoured, solid, flexible or conformal substrate with one or more lanthanide elements and then activating (e.g. neutron irradiation) the elements such that its resulting radioisotope emits beta-particles into the diseased skin surface when applied to the patient's skin. Novel processes are described for fabricating and irradiating the lanthanide-based skin patch, for example a holmium-based skin patch.
