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
The Resistance to Theory The Resistance to Theory "The Resistance to Theory" is an essay by Paul de Man (1919–83), a renowned literary critic and theorist belonging to the Yale School of Deconstruction, which appeared in "Yale French Studies" 63 (1982) and was widely anthologized. The essay later became part of the book by the same name. The essay remains a key statement in poststructuralist approaches to literary studies. Paul de Man says that the essay was written at the request of the Committee on the Research Activities of the Modern Language Association as a contribution to a collective volume entitled "Introduction to Scholarship
