The movement characteristics of five landslides are
compared and interpreted based on records of approximately
10-years duration. Condon landslide in the Oregon Coast
Range has consistently exhibited brief (1 - 8 days) movement
episodes in wet winter months, separated by long periods of
no movement. The translatory movement is probably...
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...
Previous research has shown a gap between chemistry students' conceptual
and computational understandings of chemistry topics such as gas laws,
equilibrium, and reactions. This qualitative study examined the conceptual and
computational understandings of stoichiometry of college students enrolled in a
large lecture Introductory Chemistry course. Factors that might influence students'...
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...
