In the process developed by Franks's group, cells are undercooled, without the use of a cryoprotectant, down to -30|C in droplets that are suspended in an inert oil emulsion.
This power-law relation has been observed between dendritic growth and degree of undercooling in undercooled melts.
If disc cavity temperatures are under the limits that they are controlled to then the engine is being overcooled; if they are over the limits then the engine is being undercooled. The trends should be plotted for a range of ambient conditions and engine load variations.
An effective blending is inhibited when temperature and viscosity contrasts between two magmas are large and when the proportion of the mafic/intermediate end-member magma is small (typically < 50%), because the mafic/intermediate magma is undercooled to form isolated magmatic inclusions or enclaves in the felsic magma (Eichelberger, 1980; Bacon, 1986; Sparks and Marshall, 1986; Vernon et al., 1988; Stimac et al., 1990; Clyne, 1999; Gencalioglu Kuccu and Floyd, 2001; Coombs et al., 2002; Alpaslan et al., 2005).
Politecna della Marche, Italy) concentrate on the applicability of models, mainly concerned with achieving reliable values for thermal conductivity coefficients and dynamic viscosity coefficients of organic liquids in their saturated or slightly undercooled state.

Some rooms on the second floor were slightly undercooled for both systems during 100% operation.
Rather it is a continuous optimization across a wide spectrum of conditions that can include fan failures, extreme CPU use, swappable components, and various environmental conditions ranging from overcooled to undercooled to facility cooling failure.

A comparison between HWRF SST forecasts and climatological buoy data performed by HRD (Cione and Uhlhorn 2012) suggested that the HWRF ocean undercooled in the wake of tropical cyclones.
Indeed, in all the cases it has been observed that spherulites appear and grow when the storage modulus is still constant at the first plateau value (representative of G' for the undercooled melt at [T.sub.c]).
