The low-cost production of urea in large quantities has been widely studied by chemical engineers, and a number of processes have been developed, both in this country and abroad, which reflect considerable sophistication in engineering technology and in the use of specialized allo

However, because of the technical problems involved, its application to metallic systems has not been generally realized. Such considerations as operating at fairly ele

Puppetry and the Spanish Civil Warhe laboratory has greatly increased with work on the solid state of matter. Frequently, the crystals must be of a specific lattice orientation for determination of physical and mechanical properties in the various crystallographic directions. An urgent need for such oriented single crystals led to t

Dynamic Behavior of the Isothermal Well-Stirred Crystallizer with Classified Outletysis and is one of the most difficult to operate continuously in a steady state manner. One problem which makes the control of crystallizers difficult is their sensitivity to small upsets and their tendency toward unstable behavior characterized by low frequency cyclic fluctuations of the particle size (6, .).
