The sudden collapse of a growing, viscous, gas-filled lava dome, as well as the spilling or "boiling over" of material from an eruptive vent can also trigger pyroclastic flows, particularly when the ground is steep enough, allowing gravitational forces to essentially drag them out.
The player grows slick with viscous, fresh blood, while that from earlier encounters darkens and dries; they are drenched, clogged, and caked with blood the deeper they progress.
Together, these results indicate that resistance should not spread within a microbial population under group-beneficial selection, even if grown in a viscous or spatially structured environment, as long as the colony-to-colony distance is smaller than the diffusion distance of secreted goods.
But for high injection concentration the miscible viscous fingers grow very fast and reach the oil bank.
Although the condition for the onset of the buckling instability of the film on a glass layer is the same as that for a compressively-stressed free-standing film, the instability of the film on the viscous substrate grows slowly, with a typically long characteristic time.
The elastic and viscous parts grow and decreases, respectively, to keep constant the total shear stress.
The addition of PMMA meant that the crystals were growing slowly in a more viscous medium and the retardation effect of the amorphous diluent on the kinetics of these processes resulted in the tendency to create stable and more perfectly ordered structures.
As a result, the elastic stress component grows along time, whereas the viscous stress part decreases.
Highly explosive eruptions such as occurred at Mount St. Helens commonly result from gas bubbles nucleating, growing, and rising in a highly viscous magma.
In this case, the adsorption is ruled by the intrinsic viscous forces within the growing particles rather than the hydrophobicity of the polymeric segments.
This leads to believe that the viscosity of polymer particles or viscous forces within the growing particles can create resistance to silica particle penetration into the growing polymeric particles.
