The present invention relates to substituted 1,2-ethylenediamines of general formula wherein the groups R1 to R15, A, B, L, i as well as X1\u2014X4 are defined as in the specification and claims and the use thereof for the treatment of Alzheimer’s disease and similar diseases. The color representation is generated by displaying at least one color characteristic related to a movement parameter of the structure, such as mean velocity or mean strain rate. Each memory access query has a different result table which is based on different fields. The source and drain films are made of an alloy of silicon and germanium. Consequently the combination has much lower toxicity than the known vanadium compound alone, which is a crucial advantage of the former for its use in the treatment andor prevention of Diabetes mellitus. The diffusion film cooling hole includes a first sidewall having a first radius of curvature about an axis generally orthogonal to a centerline of cooling fluid flow through the diffusion film cooling hole and a second sidewall having a second radius of curvature about an axis generally orthogonal to the centerline of cooling fluid flow through the at least one diffusion film cooling hole.
