The phase transformation from liquid to solid is a phenomenon
central to a wide range of manufacturing and natural processes. The
presence of phase transformation can drive convection in the melt
through the liberation of latent heat, the rejection of solute, and
the change of density upon freezing. The fluid mechanics itself can
playa central role; the phase transformation can be strongly
altered by convective transport in the liquid through the
modification of the thermal and solutal environment of the
solid-liquid interface; these local fields control the freezing
characteristics at the interface. The convection can be generated
naturally by buoyancy forces arising from gradients of temperature
and concentration in the liquid, by density changes upon freezing,
and by thermocapillary and solutocapillary forces on liquid-solid
interfaces. The interactive coupling between solidification and
convection forms the subject of this volume. Such coupled processes
are significant on a large range of scales. Among the applications
of interest are the manufacture of single crystals, the processing
of surfaces using laser or molecular beams, and the processes of
soldering and welding. One wants to understand and predict
macrosegregation in castings, transport and fractionation in
geological and geophysical systems, and heat accumulation in energy
redistribution and storage systems. This volume contains papers
presented at the NATO Advanced Research Workshop on "Interactive
Dynamics of Convection and Solidification" held in Chamonix,
France, March 8-13, 1992.

If you are looking for your typical zombie story, then this isn't
it....it's way more fun A soldier who grew up hating zombie films
and lore is thrown into his worst nightmares come to life, but with
the whole world at stake, the dead aren't the only things nipping
at his heels.
