Salinity, temperature, oxygen phosphate, nitrate and silicate
observatIons were taken by Oregon State University on 21 hydrographic
cruises in the Northeastern Pacific Ocean during 1968. Alklinity , pH
and total CO2 were taken on special occasions. Fifteen cruises were
taken along the Newport line. The rest were special cruises made...
The model-reference, adaptive control concept is based on the
precept that desired control system performance is a known design
requirement and can be obtained from a representative model. Control
system parameters are adjusted by the adaptive controller through a
minimizing operation on a function of the error (i.e., performance
index)...
Steroid organoboranes have been found to be useful synthetic
intermediates. Attempted pyrolyses, based on simple trialkylborane
cyclizations, have not yielded C-19 or C-18 functionalized steroids,
but have produced isomerized systems not otherwise available.
Thus, hydroboration of cholesterol followed by pyrolysis at
215° gives 31% of 2-cholestene-6α-ol and 49% of a...
