Provided is a photoelectric conversion element that has an nip structure formed of amorphous silicon and that is improved in energy conversion efficiency by a structure in which an n+-type a-Si layer is in contact with a transparent electrode formed by an n+-type ZnO layer. A therapeutic agent and method for preventing an acute rejection in a transplanted organ and improving prognosis are provided. Operated at supersonic speeds, the inlet stabilizes an obliquenormal shock system in the gasdyanamic flow path formed between the gas compression ramp on a strake, the shock capture lip on the adjacent strake, and captures the resultant pressure within the stationary external housing while providing a diffuser downstream of the compression ramp. The blocking occurs when the mailed task was mailed to an idle third thread. The detection system then identifies the group of the target image based on the group identifier of the target hash code.
