A special case of a parallel multiprocessor scheduling (MP) problem
is investigated. A set of jobs with a known process time and a.resource
requirement is scheduled on machines controlled by processors,and
the total changeover cost between jobs is to be minimized. Each processor
may control up to two machines and...
The loss of all deuterium labels from previous feedings of [2-²H]-,
[3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy
of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the
biosynthesis of the streptolidine portion of streptothricin F (la).
In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]-
arginine (32) was...
