Although of course we Italians would be foolish to even try to emulate our Swedish friends as far as efficiency of organization is concerned, we decided at the very beginning that, as far as the Proceedings were concerned, the VIIIth I

Shear-Thinning Effects in Creeping Flow about a Spheretagnation points and the volume of fluid far from the sphere do not contribute significantly to the total drag of a sphere, then a power law description of the flow field may yield an acceptable result for the drag.

A Two-Dimensional Asymmetric Flow of a Viscoelastic Fluid in a T-Geometry interest towards problems which are industrially relevant has focused attention on flows associated with abrupt changes in geometry. Numerical treatments of such flows have appeared in the literature. since 1976.

About a Possible Cause of Viscoelastic Turbulencennel flow in a plane capillary is investigated. The spatial variation of shear velocity causes a complication of the theory which is avoided by first studying the stability of plane Couette-flow between parallel plates. Then it is shown that the same mechanism for instability, found here, is also responsible for instability of plane channel flow.
