The tosylhydrazones of exo-3-deuteriocamphor and 2- deuterio-2,4-dimethy1-3-pentanone were treated with Nbromosuccinimide (NBS) and pyruvic acid to regenerate the parent ketones. The ketones from the pyruvic acid cleavage show a significant loss of deuterium. The ketones from the NBS cleavage show no loss of deuterium, indicating that stereochemical integrity at.

Models were developed that described cohort strength of female
Dover sole (Microstomus pacificus) and female English sole (Parophrys
vetulus) in stocks off the Columbia River as functions of environmental
variables. The environmental variables considered were those
that could hypothetically influence spawning success or survival.
