They are generally low-pressure machines designed to overcome friction and either suction or discharge-system pressure.
The feeders operate by either friction or suction.
Friction can be either induced by micro-slipping or macro-slipping.
Nature is full of non-smooth nonlinearities that are usually related to either friction phenomena or the discontinuous characteristics of intermittent contacts.
Friction was measured either on areas much smaller than the diameter of the tubes, which was determined from height profiles or on areas larger than the tube diameters, but smaller than the curvature radius of the AFM tip.
"[M]ost of the people who were [causing the friction] are either out of the White House or going," Dean said.
In sum, the Supreme Court's Noel Canning decision upholds the D.C. Circuit's outcome, but repudiates its reasoning and leaves the elected branches with pretty much the same tools already available to them to foster either friction or cooperation.
As a preliminary step, Proposition 2 first confirms that higher levels of either friction prompt an increase in the equilibrium price.
The possibility of friction with either the authoritarian state or non-state actors (political and religious extremists) often makes for a degree of self-censorship.
It might be attributed to either mechanical friction of the wooden planks or aging of the binding medium.
