Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
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
