The Entrainment of Small Particles by a Turbulent Spot,recorded using high-speed photography (at 2000 frames/s). Scanning the films using a motion-analyser shows several types of particle movement and the measured entrainment velocities and heights indicate the particles stay within the spot structure.

Essener Beitr?ge zur Mathematikdidaktikether, and how, such models should be amended to incorporate the effects of ambient wind shear. As is desirable, the proposed changes do not materially alter the simplicity of box models, which is their most important practical advantage.

It is also shown how such models can be used to provide more general information on the detailed turbulence structure within a heavy gas cloud. A currently available 3D heavy gas dispersion model is also described, and examples given of typical applications.

Funktionalismus und Neofunktionalismus layer, even after the short gravity spreading phase..As expected, vertical diffusion coefficients are distinctively smaller as in the atmospheric boundary layer..Turbulence induced by the vapour cloud has a noticeable effect on diffusion..More data are needed and must be evaluated to support these findings.

Zur Autonomie der Literaturwissenschaft,rtaken to assess the validity of the wind tunnel modelling technique as a dispersion prediction method [1]. The comparative data used was that obtained from the field trials carried out at Porton Down in 1976/7. In addition a number of scaling experiments were carried out in order to further investigate the modelling technique.
