Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
Memorial to the German Resistance the German resistance in the broader sense. Historians agree that there was no united, national resistance movement in Nazi Germany at any time during Hitler's years in power (1933–45). Joachim Fest describes it as "the resistance that never was." Nevertheless, the term German Resistance ("Deutscher Widerstand") is now used to describe all elements of opposition and resistance to the Nazi Regime, including the underground networks of the Social Democrats and Communists, The White Rose, opposition activities in the Christian churches (e.g. the Confessing Church), and the resistance groups based in the civil service, intelligence organs and armed forces.
