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
German resistance to Nazism German resistance to Nazism German resistance to Nazism (German: "Widerstand gegen den Nationalsozialismus") was the opposition by individuals and groups in Germany to the National Socialist regime between 1933 and 1945. Some of these engaged in active resistance with plans to remove Adolf Hitler from power by assassination and overthrow his regime. The term "German resistance" should not be understood as meaning that there was a united resistance movement in Germany at any time during the Nazi period, analogous to the more coordinated Polish Underground State, Greek Resistance, Yugoslav Partisans, French Resistance, Dutch Resistance, Norwegian resistance movement and Italian Resistance.
