Coronal plates of the sea urchin Strongylocentrotus purpuratus have a microstructure typified by smooth textured trabeculae. When plates were decorated with calcite crystals each rhombohedron had the same orientation regardless of its location on the

The reasons for the low recovery of thiamine from flour fortification mixtures containing ingredients used for the treatment of flour, in addition to iron, vitamins and chalk, are examined. The presence of potassium bromate and chalk is shown to be t

The effect of pressure to 300 kbar has been measured on the lattice parameters of Al2O3. Corundum has a rhombohedral unit cell and is relatively incompressible (∼9% in 300 kbar). Perhaps the most intersting feature involves an increase of the rhomb
