In the production method of the present invention, the polyamide is produced by the polycondensation of a diamine component and a dicarboxylic acid component comprising a straight-chain \u03b1,\u03c9-aliphatic dicarboxylic acid and an aromatic dicarboxylic acid. Each of the function parts provides a different function with respect to a signal input through the bus. The bracket includes several configurations that are tailored to the mounting conditions required. The first hole is formed in such a manner that the inserted fixing element in the first hole detachably couples the balancing weight element to the movable turbine part in a spatially fixed position. The invention describes compositions, vectors, and methods of use thereof, for the generation of transgenic cells, tissues, plants, and animals.
