Epidemiological and animal experimental studies of the fibrogenic and carcinogenic properties of natural mineral fibres in human lungs resulted in the development of man-made mineral fibres as substitutes for asbestos containing material. To evaluate the fibrogenic and neoplastic potency of man-made mineral fibres, rockwool fibres were investigated...

The objective of this doctoral thesis is to clarify the exact causes of the production of CO and HC emissions relevant for the partial-load range of the engine and to indicate capabilities of reducing the same. For this purpose exhaust gas samples were taken at 264 locations within the flame tube of a DART tubular combustion chamber and analyzed fo...

Several aspects of classical and quantum mechanics applied to a class of strongly chaotic systems are studied. The latter consists of single particles moving without external forces on surfaces of constant negative Gaussian curvature whose corresponding fundamental groups are supplied with an arithmetic structure. It is shown that the arithmetical ...

This paper studies tandem cascades which make possible variations on the cross section ratios in overlapping regions by changes in the circumference and rotation in the second cascade row. Particular value is attached here to the influence of the overlapping regions of both cascade rows, without changing the geometrical measurements in the deflecti...
