A survival hook consisting of a pair of hooks rotationally attached to a plate which is itself provided with fastening means to retain the plate over clothing, typically over the forearm of a user. Of the two tubes, at least one tube serves as a measuring tube conveying flowing medium and the other tube is mechanically connected with the tube by means of a first coupling element to form an inlet-side coupling zone and by means of a second coupling element to form an outlet-side coupling zone. For each pair of adjacent openings of the at least one column of openings, the shading panel comprises a first shading louver and a second shading louver, the first shading louver being positioned closer to the opening of the pair of openings closest to the upper border, the second shading louver being positioned closer to the opening of the pair of openings closest to the lower border. A turbine blade creep elongation strain measuring apparatus 20 comprises a first fixed end 21, a second fixed end 22, and a dial gauge 24. A third photomask process is conducted to pattern a transparent conductive layer for forming a pixel electrode. The described invention also includes methods of making such pyrimidine derivatives as well as methods of using the same in the treatment of hyperproliferative diseases.
