At first glance, the averaged dyad of velocity components is symmetrical, == However, if averaging is performed over the plane with normal nj, the principle of commutation is lost. As a result, the stress tensor asymmetry j is determined by other factors that participate in the angular ...
The principle of conservation of angular momentum states that angular momentum is conserved if no net torques are involved. Angular momentum is of particular interest to the musculoskeletal clinician as joints move using angular motion around a joint axis. This angular momentum is often referred to ...
−(w, d(ρν ⊗ ν)), (3.21) 4 Other Fluid Models The above calculation establishes the principle that allows us to obtain equations in conservation form by playing off the terms gained from the variational principle in (3.8) with those obtained by an infinitesimal change of variables ...
Unlike energy, momentum has units that are not given a special name in either system of units. Therefore, the units of momentum are kg·m/s and slug·ft/s. In order to consider the conservation principle associated with momentum, let us reconsider Newton's second law,∑F = ma, in ...

In principle, this could be ascribed either to an arrest transition or to the transition from the Hughes regime to the Saffman-Delbruck37 regime, as the latter predicts a weak loga- rithmic dependence of the diffusion coefficient on the radius R. However, we rule out this latter hypothesis, ...
