The growing demand for water in the arid regions of the West
increases the need for optimal allocation of water among competing
uses. An efficient allocation of water between instream and out-of-stream
uses has been impeded by institutional constraints and the
scarcity of information regarding instream flow benefits. The
objectives...
A modeling technique for simulating the noise
performance of chopper-stabilized switched-capacitor
filters using SPICE2 is presented. A method for
selection of switched-capacitor network (SCN) stages
to be chopped and an op amp topology for low noise
applications are also outlined. Validity of the
modeling is verified by the close agreement...
A short-circuit-protected line-driver circuit is
particularly adapted for use in a CMOS differential line-driver
system, where one line-driver circuit provides a
true output signal, and another line-driver circuit
provides a complementary false output signal. A short-circuit
is sensed by measuring current through a secondary
pull-up transistor, and disabling a primary...
The objective of this thesis is to assess four winter feeding programs of spring-calving brood cows that may improve profitability to ranching operations of the Harney Basin, Oregon. The four feeding strategies include strip grazed rake-bunched hay, supplemented range grazing, strip grazed meadow pasture, and baled hay feeding. These first...
A comparative study was done on data collected by Weyerhaeuser
Company on l,6144 second-growth Douglas-fir, Pseudotsuga menziesii,
trees. The variable used in the study was the percent difference,
positive or negative, between the volumes given by each of three
different log rules and the standard tree volumes determined by
Weyerhaeuser...
A comparison of alternative pharmacy fee systems in a
community hospital was studied.
A retrospective analysis of FY 80 financial reports for
an 83 bed community hospital was used. This data base was used
to determine the economic impact of various pharmacy charging
systems in a typical community hospital and...
Three approaches for evaluating mode I interlaminar strain energy release rates in graphite/epoxy composites were compared using experimental data from double cantilever beam specimens. Expressions for evaluating strain energy release rates were arrived at based on assumptions regarding specimen geometry and material behavior. The calculations included the direct method of...
Two new concepts have been explored in solving the neutron
diffusion equation in one and two dimensions. At the present time,
the diffusion equation is solved using source iterations. These
iterations are performed in a mathematical form which has a great
deal of physical significance. Specifically, the neutron production
term...
The purpose of this study was to assess the attitudes of students, teachers, and principals toward skills taught in consumer and
homemaking education. The sample included 35 principals, 58
teachers, and 272 students in Oregon secondary schools. Respondents'
attitudes were assessed by analyzing the data on the basis of the...
This study was a comparison of the prevalence of infectious
gastrointestinal disease and the quality of construction of individual,
surface source water systems in Lincoln County, Oregon.
Two measurement instruments were developed for this study. An
objective instrument was developed to determine if the water systems
observed in the study...
While there are many people who feel it is impossible to place a monetary value on a recreation resource, economists argue that not only is it possible to do so but also necessary because so many recreation sites are publicly provided. There have been various methods used to value non-market...
Computer codes for versions of STORM, capable of calculating power distributions in a three-dimensional quarter-core of a boiling water reactor, were developed by using both a modified one-group and two-group diffusion theory model with several different power calculation schemes. Several numerical examples that demonstrate the high efficiency of the coarse-mesh...
Concerns regarding the most effective means of evaluating
segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method
were grown in a replicated yield trial. The effectiveness of each
method was measured in terms...
The purpose of this research was to compare two instructional
programs of inservice training on Personal Hygiene for hospital foodservice
employees for knowledge retention and cost effectiveness.
The two instructional methods used were lecture discussion with a
script and transparencies and the individual instruction with cassette
tape and slides.
The...
In 1968, a study conducted by the sanitarians of the State Health Division and Benton County Health Department revealed a high failure rate of on-site sewage disposal systems in Southwest Corvallis. The survey team concluded that sewage disposal in this area was inadequate, and a significant health hazard existed due...
