Bulge mixing

One might note the striking similarity between Cases I and II. In both, a crucible failure allowed water to enter and mix with molten titanium. Steam (and hydrogen) formed and the pressure increased so as to bulge the crucible and rupture the safety discs. Tamping the water-metal mix by the fall of the electrode then caused a major explosion. No injuries resulted in the Case II incident because the vault walls provided protection. No data were available to allow an estimation of blast pressures, but as described, the vault construction maintained its integrity and the wave was forced to exit from the bottom.

Stored Foodstuffs Canned foods and unopened dry mixes will stay fresh for up to 2 years if stored in a cool, dry place away from any heat source. Cans that bulge or leak should be discarded. Flooded food supplies not in cans should be discarded. All stored food containers should be dated to monitor and rotate for maximum freshness. 

The solid-liquid interface in Fig. 18.55a bulges into the melt because of the transparency of the crystal. Buoyancy-induced melt convection (Fig. 18.55b) sharpens the interface, but the interface still protrudes downward. As crystal rotation is applied, as in Fig. 18.55c, mixed convection is induced within the high Prandtl number melt. Melt convection, in conjunction with solid-phase conduction and radiation, flattens the interface to a shape similar to those observed experimentally upon crystal rotation. The interface is further flattened with increased rotation, as in Fig. 18.55d. 

Figure 12-4 Differential binding of IRPl and IRP2 to natural IREs (Iron Responsive Elements). P-5 -RNAs (n = 29-30 nucleotides) were melted and annealed before mixing with recombinant IRP proteins (The proteins were kindly provided by E. A. Leibold, University of Utah, and W. E. Walden, University of Illinois). RNA-protein complexes were separated from RNA by electrophoresis in non-denatuiing polyacrylamide gels [20]. Per contains an internal loop/bulge (Figure 12-3), and TfR, eALAS, and m-aconitase IREs have C-bulges. Per mutation AU6 converts the Per internal loop/bulge to a C-bulge. Per ferritin TfR transferrin receptor eALAS erythroid amino-levulinate synthase and m-aconitase. No IRE/IRP complex was detectable.
