## Abstract We study the asymptotic behaviour in time of incompressible nonโNewtonian fluids in the whole space assuming that initial data also belong to __L__^1^. Firstly, we consider the weak solution to the powerโlaw model with nonโzero external forces and we find the asymptotic behaviour in tim

The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a relaxation time, z, consistent with the observation that the timescales of both volume and shear relaxa
A new way of investigating the relaxation processes of polymeric systems confined between solid surfaces is presented here. The test is based on draining experiments by means of a surface force apparatus and consists in monitoring the hydrodynamic force release following a drainage motion. Experimen
