commercially in a new continuous-process plant at South Charleston, W. Va. Page 1665. • Compression distillation and electrical membrane processes for conversion of salt water to potable will be studied under two new Department of Interior contracts. Page 1666. • Physiological d a m a g e from exposure t o radiation can be explained through application of biochemical techniques. Page 1666. • The absolute thermodynamic s c a l e should be based on a single fixed point, according to recommendations of t h e National Research Council and the Bureau of Standards. Page 1668. • S o v i e t nuclear physics is embroiled in a political controversy similar to the Lysenko case in genetics. Page 1672. ^ A new group of vulcanization a c c e l e r a t o r s ,
the alkyl sulfenyldithiocarbamates derived from secondary amines, offer exceptional scorch resistance and faster curing. Page 1676. ^ Almost 1 1 % more c o t t o n s e e d oil and 5.4% more edible oils would b e available to the U. S. with an industry-wide shift from the hydraulic to the prepress-solvent process. Page 1678. Y A recording ellipsomefer which permits continuous measurement of adsorbed layers may give more complete answers to problems on adsorption properties of surfaces. Page 168G. ^ Lifting the U. S. e m b a r g o on exports t o Red China will undoubtedly be discussed at the Geneva conference. Page 1682. V O L U M E
