This section is a bit of a mixed bag! Rheology is everywhere with many subsets twists and turns. Below are three presentations that concentrate on different areas of rheology. **Shear Thinning** is a very common feature of complex fluids where the general trend for a wide range of fluids is rather similar; however the reason for the shear thinning can be very fluid specific.

Rheology is everywhere with many subsets twists and turns. Below are three presentations that concentrate on different areas of rheology. **Shear Thinning** is a very common feature of complex fluids where the general trend for a wide range of fluids is rather similar; however the reason for the shear thinning can be very fluid specific. The presentation below puts the topic into perspective and it also introduces an initially surprising result that the apparent viscosity of a suspension can, in some ces fall below that of the matrix fluid.

The second presentation is about **Extreme Rheology **where one the one hand, linear viscoelastic measurements are made on very low viscosity fluids at very high frequency in order to detect short relaxation time viscoelastic behaviour. Whilst at the other end of the spectrum, extensional flow data is obtained for very high viscosity polymer melts.

Finally a presentation on **“The Rheology of Swallowing” **is given where the rheology of so called dysphagia fluids are presented, together with a laboratory “human throat”!
