Vascular resistance is a fluid layer in which at a distance δ, viscosity η is a function of δ written as η(δ), and these surrounding layers do not meet at the vessel centre in real blood flow. Instead, there is the plugged flow which is hyperviscous because holding high concentration of RBCs. Thurston assembled this layer to the flow resistance to describe blood flow by means of a viscosity η(δ) and thickness δ from the wall layer. The blood resistance law appears as R adapted to blood flow profile : where Blood resistance varies depending on blood viscosity and its plugged flow
The Resistance to Theory aesthetic approach to literary studies and those who uphold an historical approach both find theory inconvenient and challenging. They are the polemical opponents of theory. As theory is as much a linguistic construct as literature, it falls prey to the same problematics of literary language. De Man states that the resistance to theory may be "a built-in constituent of its discourse." The real debate of literary theory is henceforth "not with its polemical opponents but rather with its own methodological assumptions and possibilities." (p. 358) This is because "the resistance to theory is a resistance to the use of language
