The nature of the bioluminescence of Gonyaulax catenella is
similar to that observed for other dinoflagellates in culture, showing
photoperiod-entrained rhythms of luminescence and stimulability
with relatively constant luminescent capacity during scotophase. G.
catenella is very sensitive to stimulation and photoinbibition. The
nature of the response to stimulation by bubbling...
Reproductive characteristics of introduced eastern cottontail
rabbits, Sylvilagus floridanus (J. A. Allen), were determined from
486 rabbits collected between January 1, 1968 and June 30, 1969,
near Corvallis, Oregon.
Sex ratios were 1:1 for all rabbits collected and for all embryos
20 days or more gestation. On the basis of...
Purpose of the Study
The basic purpose of this study was to examine the attitudes and
opinions of community college personnel toward faculty involvement
in policy formulation.
Procedures
The statistical and subjective data for this study were obtained
from two major sources. (1) A statistical questionnaire was
developed to identify...
This study was undertaken to determine the sorts of polygalacturonases
present in the culture filtrate of Fusarium oxysporum
f. sp. lycopersici, to purify and characterize these enzymes, and to
study any complexes that may form between polygalacturonase and
carbohydrate not degraded by the enzyme.
The polygalacturonase in culture filtrate consists...
The relationship of x-ray tube housing temperature to duty
cycle was studied for a superficial therapy x-ray installation, a
dental radiographic installation, and a rotating-anode medical diagnostic
installation. Thermistors were used to measure the tube
housing temperature at points selected to be representative of
thermal conditions on the surface of...
This analysis concerns the life and scientific work of Henry
Augustus Rowland (1848-1901), organizer and the first chairman of
the physics department at The Johns Hopkins University in 1876.
Special materials used in this research included three pieces of
Rowland's experimental apparatus which are extant in the Smithsonian
Institution Division...
This thesis reports the results of a study on the influence of biologically
stabilized kraft mill effluent (SKME) on the food relations and
production of juvenile chinook salmon, Oncorhynchus tschawytscha
(Walbaum), in laboratory streams. Experiments were conducted at
the Oak Creek Fisheries Research Laboratory, Oregon State University,
during 1967 and...
Studies were initially conducted to determine the action of
intravenous serotonin on perfused segments of human umbilical
cords in vitro. Intravenous serotonin, via bolus injection or
continuous infusion, was found to elevate venous perfusion pressure,
while intra-arterial serotonin failed to alter venous pressure.
Norepinephrine, administered to the venous perfusate, was...
