Biofluid dynamics is also an example of a biological fluid. Types of Fluids Fluids can be classified into four basic types. They are: An Ideal Fluid is a fluid that has no viscosity, means it will offer no resistance, pragmatically this type of fluid does not exist. It is incompressible in nature. Real fluids are compressible in nature. They offer some resistance and thus have viscosity. All Fluids existing are real fluids. A Newtonian Fluid is a fluid whose viscous shear stresses (acting between different layers of fluid and between the fluid layer and surface over which it is flowing) are directly
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.
