Vascular resistance recent results showing the sheath flow surrounding the plug flow in a vessel, the sheath flow size is not neglectible in the real blood flow velocity profile in a vessel. The velocity profile is directly linked to flow resistance in a vessel. The viscosity variations, according to Thurston, are also balanced by the sheath flow size around the plug flow. The secondary regulators of vascular resistance, after vessel radius, is the sheath flow size and its viscosity. Thurston, as well, shows that the resistance R is constant, where, for a defined vessel radius, the value η(δ)/δ is constant in the
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.
