Alkaline tailings from a salt work and a soda plant have been pumped into the southernmost part of Traunsee at Ebensee for many decades. A survey in 1981 showed an accumulation of more than 3 × 106 m3 alkaline mud in the Bay of Ebensee and the existence of slumping structures and turbidites in the profundal zone of the lake. A new survey of the industrial tailings has been performed in 1999. Compared to the earlier survey, the accumulation in the Bay of Ebensee has grown to >4 × 106 m3, which suggests an average yearly input of 90 000 m3. Slumping structures and turbidites document the unstable situation of the tailings near the waste inlet. The lake area occasionally affected by the turbidity currents in the profundal zone has increased to 19%. Within the central profundal area these tailings reach <1 m in thickness. 相似文献

This paper describes a new dynamic testing procedure of individual lift capability and its laboratory evaluation with 39 subjects. In test-retesting, the isoinertial “LIFTEST” proved to be less variable than standard isometric lift tests. 相似文献

Body dimensions are main determiners of equipment dimensions. Design for the “average user” is not suitable. Selected percentile values at the lower and upper extremes of the variable distribution determine minimum and maximum equipment dimensions or adjustment ranges. Interactions among design variables must be considered. This paper applies this rationale to the determination of major equipment dimensions of video display terminal (VDT) workstations. While the approach is generally usable, the specific data describing the U.S. population used in this paper indicate design ranges appropriate for North America. Since American body dimensions are quite comparable to most European data, the equipment dimensions should also be suitable for use in Europe. 相似文献
