The dynamics of a cross-flow, packed tower were investigated
as a new alternative for gas-liquid contacting.
At the present time there are two methods of gas-liquid
contact, co-flow, and counter-flow, both having known
limitations. This investigation studies cross-flow contact
in an effort to eliminate the lower limits of gas-liquid
flow...
Covers July 1, 1970 to June 30, 1971. Reports on studies of spawning and larval rearing of Manila littleneck clams, native littleneck clams, butter clams and gaper clams, including field work. "Field studies comparing growth and survival of laboratory-reared and imported Pacific and Kumamoto oysters were completed. We continued studies...
Cores taken from the ridge areas of the Gorda-Juan de Fuca
plate have a sedimentation rate that is appropriate for the study of
late Quaternary stratigraphy. An analysis of the clay and silt
mineralogy of the cores using X-ray diffraction methods and by
noting changes in the foraminiferan-radiolarian abundances in...
The study of parent attitudes in Portland, Oregon, elementary
schools was designed to accomplish three purposes: (1) To identify
the attitudes of Non-Negro parents toward integration of Negroes into
the schools and community, (2) To measure the effects of socioeconomic
classes (low, middle, upper), of schools (control versus
transfer), and...
This study evaluates the Earth Resources Technology Satellite-
One (ERTS-1) multispectral scanner (MSS) as a means of predicting
lacustrine trophic state and the magnitude of selected trophic state
indicators.
Numerical classificatory methods are employed to ascertain the
trophic character of 100 lakes in Minnesota, Wisconsin, Michigan,
and New York using...
The main objective of this research was to determine the professional
in-service development needs of fourth, fifth, and sixth grade
teachers in the metropolitan school districts of Portland and Seattle.
The primary objectives for conducting this research investigation were
as follows:
