Visualization in Scientific Computing (
VISC) is emerging as a major computer-based field, with a body of problems, a commonality of tools and terminology, boundaries, and a cohort of trained personnel.

Visc. (nv) Z10+++ Appearance clear
Called REX, the reactive-extrusion module can predict process parameters for peroxide "
visc breaking," grafting of monomers onto alpha olefms, and dynamic vulcanization.
The most apparent contrast between the two latexes is the [[phi].sub.w] where satisfactory
visc osities are attained.
