The portion of the East Pacific Rise (EPR) between 5° and 12°S
can be subdivided into three areas by fracture zones that offset the
rise axis at about 6.5°S and 9°S. In all three regions, the spreading
axis of the EPR is defined by a topographic block 300 to 350...
I have developed an analytical method for the determination of
molecular hydrogen in seawater. It is based on the change of hydrogen
concentration in a 30 cc. volume of air as it is equilibrated with a
one-liter sample of seawater. The change in hydrogen concentration in
the air is measured...

Consider the situation where one is faced with a sequence of knapsack type problems which involves additional constraints on the permissible number of certain types of knapsack fillers to be used over the sequence. This research is concerned with determining good and perhaps optimal solutions which maximize the total value...
For continuous time, finite state and action, Markov decision
chains, optimal policies are studied; (i) a procedure for transforming
the terminal reward vector is given and it is established that this
transformation does not alter optimal policies, (ii) decision chains
with absorbing states are studied and the results obtained are...
It can be hypothesized that the degree to which students value
learning in the visual arts influences the amount of involvement in
art oriented activities that will be pursued in later years. This
investigation has compared former college students° valuations of the
Basic Design course with levels of art interest...
During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...
Observed intensity fluctuations in the emission of Starkperturbed
Ly-α and Ly-β radiation from beam-foil formed atomic
hydrogen are compared with theoretical calculations to yield information
on the relative cross sections for creation of a hydrogen atom into
the various l -levels for n = 2 and n = 3. It...
Investigations with ram semen were conducted to develop procedures
of cyrogenic preservation that would provide long-term
retention of fertilizing capacity in ram spermatozoa.
An isotonic extender consisting of egg yolk, sodium citrate,
lactose, glycerol, and a broad spectrum antibiotic was selected from
among several extenders tested in pilot studies. Using...
