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 concept of "Resistenz" leads to a levelling down of fundamental resistance against the system on the one hand and actions criticizing more or less accidental, superficial manifestations on the other: the tyrannicide appears on the same plane as the illegal cattle-slaughterer". Moreover, Hofter noted that the things that Broszat labeled "Resistenz" had no effect within the grander scheme of things on the ability of the Nazi regime to accomplish its objectives within Germany. Another of Broszat's critics, the German historian Klaus-Jürgen Müller argued that the term "Widerstand" should apply only to those having a "will to overcome the system" and
