Eine der größten Herausforderungen für die Entwicklung zukünftiger schadstoffarmer Gasturbinenkraftwerke ist die Gewährleistung eines stabilen Verbrennungsprozesses. Um die immer strikter werdenden Emissionsrichtlinien, vor allem hinsichtlich NOx, zu erfüllen, führte die Gasturbinenindustrie die Mager-Vormisch-Verbrennung ein.

Four divers were investigated simulating a diving of 350m with saturated heliox under compression, performed in Jan 1989 at Navy Medical Institute. Changes in hearing threshold, brainstem evoked response and acoustic impedance were observed. The 4 divers experienced no tinnitus, hard of hearing and earache during compression and decompression ...
