The photosynthetic activities, the pigmentation and the chloroplast
membrane polypeptides of several mutants of the green alga, Scenedesmus
obliquus, with complete or limited deficiencies in the light-harvesting
complex of photosystem II are characterized and compared to those of the
normal phenotype.. The principal phenotype examined in this study, K0 -9,...
The Department of Nuclear Engineering at Oregon State University has recently introduced a neutron radiography facility (OSNRF). The facility is dependent on a neutron source established by the OSU TRIGA® Reactor (OSTR). It was unknown how accurately a computerized model of the OSTR in conjunction with the OSNRF could represent...
Micropaleontological data have been analyzed through mathematical
and statistical procedures, in order to: (1) establish the distribution
pattern of radiolarian assemblages in the surface sediments,
(2) establish the relationship of these assemblages with oceanographic
variables, (3) determine the faunal composition down-core with
respect to the faunal surface pattern, and (4)...
This thesis
is concerned
with the
problems
which
need
consideration
when
designing
a
nanosecond
pulse
generator
having
a
repeatable
pulse
width
and
amplitude
output.
The
basic
circuit
is
first
presented
and
analyzed
and
the
reasons
for
wide
variations
in
pulse
width
with
replacement
of
transistors
are
pointed
out.

The purpose of this study was to explore some of the practices
of home economics teachers in the use of auxiliary personnel as
expressed by city and state supervisors. A second purpose was to
discover the beliefs of city and state supervisors regarding the use
of auxiliary personnel in home...
Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...
The implementation of concurrent engineering into many large
companies has greatly improved their product development processes.
These companies have seen significant gains in quality and customer
satisfaction with reduced product costs, defects, and time-to-market
(Lake, 1992). Many large companies have successfully employed this
relatively new product development philosophy. However, smaller...
Studies of the diel behavior of phytoplankton are numerous,
however, little work has been done on diel changes in neuston, the
organisms inhabiting the surface microlayer. Sampling of the
neuston and plankton of Sequim Bay, Washington was conducted on
18-19 August 1983 at four hour intervals. Neuston samples (upper 50...
