According to one embodiment, an electronic apparatus includes a housing having a receptacle, a disk drive removably housed in the receptacle of the housing, and a shock-absorbing rubber member, which is elastically deformable and interposed between the receptacle and the disk drive. The light receiving portions are formed inside electrode opening port portions which are formed through an electrode. The refarming control signal is related to a reuse of a frequency resource of a first communication technology by a second communication technology. In other embodiments, the interrogation systems include variations of metal instruments and sponges employed therewith. Thus, systems and methods are provided for the recombinant expression of dirigent proteins andor pinoresinollariciresinol reductases. The catheter includes a braided conductive member at its distal end that can be radially expanded.
