The present invention relates to a process for preparing low-viscosity reaction products of polyisocyanates containing activated, ethylenically unsaturated groups which react, with polymerization, on exposure to actinic radiation. The decoration plate includes a cover plate, a conductive ring, an insulating layer, and a conductive element. Alternatively, or in addition, the non-hybrid screening method identifies a peptide that is capable of rescuing the cell, tissue or organism from cell death or inducing a cell, tissue or organism to grow. The present invention can improve quality of services through service differentiation based on priorities of service classes and buffer management based on characteristics of the corresponding service traffics. The first pair of the four side wall portions have a locking hole locked by a locking claw on the locking wall portions.
