Abstract: A fiber-reinforced composite material having a sensor array of a plurality of sensors for structural health monitoring of the composite material, and also having electrical conducting paths incorporated in the composite material and extending through the composite material. The electrical conducting paths are arranged in a first group and in a second group different from the first group, with the first group extending in a first direction, and the second group extending in a second direction and intersecting the electrical conducting path of the first group. The intersecting paths form together with the conducting paths of first group a network of n row conductors and m column conductors. There is also a signal processing means for monitoring at least one electrical characteristic of the conducting paths.

Abstract: In a fiber-reinforced composite material (1) comprising a sensor array of a plurality of sensors for structural health monitoring of the composite material (1), wherein electrical conducting paths (4, 5) are incorporated into the composite material (1) and extend through the composite material, the electrical conducting paths are arranged in a first group and in a second group different from the first group, wherein the electrical conducting paths of the first group extend in the same direction, the electrical conducting paths of the second group also extend in the same direction and intersect the electrical conducting paths of the first group and thus form together with the conducting paths of the first group a network of n row conductors (4) and m column conductor (5), and a signal processing means for monitoring at least one electrical characteristic of the conducting paths is provided, the state of the composite material (1) as well as damages, for example by fiber cracks, should be detected spatially res

Abstract: Solid and liquid pharmaceutical preparations containing cilansetron or its acid addition salts as active substance which include an amount sufficient to stabilize cilansetron against racemization, of a physiologically compatible water-soluble acid additive selected from monobasic or multibasic organic acids having 2 to 12 carbon atoms with a first p.sub.s value between 1.1 and 4.8, acid salts of the aforementioned multibasic organic acids, and acid salts of multibasic mineral acids having a first available pK.sub.s value between 1.5 and 7.5, as well as the use of such acid additives for stabilizing cilansetron against racemization in pharmaceutical preparations.
