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
German resistance to Nazism Lieutenant Heinrich Graf von Lehndorff-Steinort: “The assassination must be attempted, "coûte que coûte" [whatever the cost]. Even if it fails, we must take action in Berlin. For the practical purpose no longer matters; what matters now is that the German resistance movement must take the plunge before the eyes of the world and of history. Compared to that, nothing else matters.” In retrospect it is surprising that these months of plotting by the resistance groups in the Army and the state apparatus, in which dozens of people were involved and of which many more, including very senior Army officers, were
