Deuterated forms of N-{3-5–2–1,3-thiazol-4-yl-2-fluorophenyl}-2,6-difluorobenzenesulfonamide and pharmaceutical compositions containing the same. The tool is of a concentric tube configuration comprising first and second elongated bodies, in which the second elongated body can be retracted into the first elongated body. The sun collector therefore provides the double function of a sun collector with a partially transparent sun protection device. The haptic effect may optionally be encoded into a data file on a first device. The sleeve pipe, which will be fused to the optical fibers, is fitted on the fixing part.
