The primary purpose of this investigation was to characterize
the lipids of the spores and vegetative cells of Cl. botulinum. A
second purpose was to explore the possibility that lipids might serve
as a means of differentiating the chiefly proteolytic Cl. botulinum
type B from the nonproteolytic Cl. botulinum types...
The purpose of this study was to investigate whether or not
change has occurred in the scholastic background and academic ability
of students attending the junior high school summer sessions of
the Santa Monica Unified School District, California, between the
years 1956 and 1962.
Applying a Fisher and Yates Table...
Taste responses of the Columbian black-tailed deer,
Odocoileus hemionus columbianus (Richardson), were determined
by use of the two-choice preference test method, where the choices
were tap water and tap water-chemical solutions in ascending
concentrations. The chemicals tested were: the sugars, glucose
and sucrose; the sodium salts of chloride (NaC1) and...
An intensive chemical investigation, that includes the
determinations of salinity, oxygen, nutrients, pH, alkalinity, and
total carbon dioxide of the Columbia River plume off the Oregon
coast in July 1967 shows the following unique features:
1. Along the axis of the river plume both the salinity minimum and
temperature maximum...

The diffusion process in a variable density, turbulent
flow is a factor which greatly influences the waste
disposal characteristics of tidal estuaries. Waste disposal
from cities and industries, is posing an increasing
threat to the estuarine environment. Accurate prediction
of the effects of proposed waste outfalls in well-mixed
estuaries (which...
Monthly samples of nutrients, phytoplankton and zooplankton
were taken in the Columbia River estuary over a period of 16 months
in order to determine distribution with season and salinity, and interrelationships
between plankton and nutrients.
Nitrate and phosphate levels in the river water entering the
estuary are high in the...
