The invention concerns a set for fixing a soft tissue, such as a ligament or tendon on a bone, comprising two nails and a member for positioning and setting the nails in the superimposed soft tissue and bone. Anhydrates and solvates of 17\u03b1-ethynyl-5\u03b1-androstane-3\u03b1,17\u03b2-diol include Form III anhydrate and Form I solvate. Thus, the copper wiring pattern becomes less susceptible to disconnection, and it is possible to provide a flex TCP semiconductor device with high manufacturing yield. The angle of the linear structuring element which produces an eroded image having the greatest surface area is designated as the skew angle. Apparatus related thereto are also disclosed. Furthermore, the gas diffusion layer is positioned proximate the first electrode layer or between first and second portions of the first electrode layer.
