Rock veneers are typically distinguished through six variables : particle size, particle density, stability characteristics, potential for storing mobile sediments, degree of abrasion, and varnishing.
22.
However, a variety of definitions of particle density are available, which differ in terms of whether pores are included in the particle volume, and whether voids are included.
23.
The nondimensionalization is in order to compare the driving forces of particle motion ( shear stress ) to the resisting forces that would make it stationary ( particle density and size ).
24.
If a small sample of powder is allowed to settle in this column, it will come to rest at the point where the liquid density is equal to the particle density.
25.
The rings have numerous gaps where particle density drops sharply : two opened by known moons embedded within them, and many others at locations of known destabilizing orbital resonances with G Ring.
26.
The particle densities tend to be in the range of 10 18 to 10 22 m " 3 and the linear dimensions in the range of 0.1 to 10 m.
27.
By increasing the particle density to close to the required energy, this technique improved the beam quality and, inter alia, brought the discovery of W and Z bosons within reach.
28.
Unique optical properties have been uncovered in dense hyperuniform materials, wherein light of a wavelength specific to the material is able to propagate forward despite high particle density due to microscopic order.
29.
However, since collisions do occur, the particle density in the phase-space volume d ^ 3 \ bf { r }'d ^ 3 \ bf { p } changes, so
30.
Where \ rho is the particle density, d is the grain diameter, \ dot { \ gamma } is the shear rate and \ mu is the dynamic viscosity of the interstitial fluid.
