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
Resistance to interrogation Abu Ghraib resembled the techniques used in RTI training. Resistance to interrogation Resistance to interrogation, RTI or R2I is a type of military training to British and other NATO soldiers to prepare them, after capture by the enemy, to resist interrogation techniques such as humiliation and torture. The trainees undergo practices such as hooding, sleep deprivation, time disorientation, prolonged nakedness, sexual humiliation and deprivation of warmth, water and food. Many of these techniques are against international law if used in interrogations. In such interrogation sessions, the subjects must maintain dead silence regardless of the practice being inflicted on them. Only
