A solar cell module includes a base body, a plurality of solar cell elements arranged at intervals over the base body, a resin layer disposed on the solar cell elements and comprising a plurality of recesses on its surface facing opposite to the solar cell elements, and a protective sheet disposed on the resin layer. The novel reagent enables the characterization, purification, inhibition and screening of Ca2+-binding proteins, as well as the preparation of a new affinity chromatography matrix and a new protein biosensor. The deposited portion includes an air bearing surface, an end surface, and at least one other surface. Tooling is provided to allow for simultaneous tightening or loosening of all bolts on a single combustor. If the load is to be decreased, the length threshold is randomly decreased according to a certain probability.
