A heterojunction bipolar transistor is doped in the sub-collector layer with phosphorus. The edge of each cutting instrument is oriented away from a resting surface so as to reduce or avoid the dulling of the edge. The plurality of longitudinal connecting members may include one or more pairs of closely-spaced longitudinal connecting members aligned substantially parallel to the longitudinal axis of the implantable frame. In the method according to the invention, at least one impregnated blended cloth is used to disinfect at least a portion of a body. The received light is subjected to data decoding so as to reproduce read-only holograms.
