A design flux injector for NMR superconducting magnets : results of operation with superconducting insert cells
… and above. Such systems generally require an HTS insert to be placed in the inner high-field region of a low temperature superconducting (LTS) magnet. Among the problems in the presently available HTS technology are splice resistance and index dissipation, which make it essentially impossible for …

Laboratory investigation of in-field influences on spectral noise attenuation and comfort of insert and circumaural hearing protectors
Laboratory-obtained, manufacturer-supplied hearing protector attenuation ratings typically overestimate the workers' protection level In the workplace. In addition, several work-related in-field factors often degrade protection performance of the hearing protection devices (HPDs), posing the threat …
