Fatal decompression sickness following therapeutic hyperbaric environment (author's transl)

In Hannover/Germany in 1976 a so called "Society for Regenerative Hyperbaric Therapy" (Gesellschaft für Regenerative Uberdruck-Therapie) subjected 20 patients within two coupled multi-place chambers to a simulated hyperbaric environment, equivalent to a maximum of 4 ata, followed usually by gradual reductions of the pressure. The patients were of an average age of 67.2 years and were afflicted by various disorders. During one of the "dives" a patient developed air embolism of the central nervous system. During ensuing confusion of the chamber was opened suddenly, with resultant explosive reduction of the high pressure. This resulted in five letal accidents of decompression sickness. Post mortem examination revealed diffuse distribution of gas bubbles throughout the entire body. By elecronmicroscopy each bubble was covered by an osmiophilic coat. Post mortem findings are discussed and correlated with well-known and new clinical symptomes. These observations present for the first time fatal accidents of decompression sickness in humans, associated with hyperbaric air-therapy.     

Diversity as a policy goal: The case of television

Diversity in communications is most appropriately understood as a free flow of ideas. In order to implement diversity, a comprehensive model of the communication process must be used for policy research, so that the various participants in the process can be properly restrained from abridging the free flow of ideas. The setting of priorities for implementing diversity has been illustrated using available studies of broadcast and cable television.     

“TOTALS”: Transfer of technology approached logically and systematically

Most efforts in transferring technology to a specific location are carried out following essentially a research approach. However, imposing the research approach onto a situation for which a specific solution needs to be created or restructured represents an inappropriate transfer of technology. A planning and design approach (PDA) is called for. “TOTALS” is based on planning and design concepts adapted to solving the problems of technology transfer. It is composed of six time-based and repeating phases, comprised of nineteen steps. It is based on four important concepts: a systems view of technology, a Technology Transfer Equation, five different purposeful perspectives regarding technology transfer activities, and a holistic PDA. No particular approach, technique, model or body of knowledge can be said to be predominant.
