This invention relates to novel substituted diazabicyclo derivatives useful as monoamine neurotransmitter re-uptake inhibitors. Then, a verifyread operation is conducted by using potential Vbi\u2032. The inner side of the reflector facing towards the light source is at least partially embodied in such a way that it forms a first focal point in the position of the light source and reflects light radiated from the light source to an incident light surface of the light decoupling element facing way from the light exiting surface. A key block is then fit into the grove, thereby holding the geomembrane in place by the tension created between the base and the key block. The environmentally acceptable fluid loss control additives are comprised of ethoxylated hydroxyethylcellulose having a reduced molecular weight.
