The increase in the number of red blood cells produced increases the viscosity of the blood.
We learn to sense how calorie-packed a food is by its sweetness and viscosity.
In contrast, in the presence of viscosity, there is no such equivalence.
Uncertainties in the magnetized plasma viscosity remain as an obstacle to unambiguous tests of the results in the case of real plasmas.
Flow approaching the sphere from upstream accelerates, forms a vortex jump beyond the equator and then decelerates slowly downstream under the action of viscosity.
There is a large increase in potential vorticity generated by the artificial viscosity, which again results in layers of enhanced static stability near the boundaries.
The dynamical system is determined by travelling-wave solutions of the associated viscosity equation.
