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...
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...
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...
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...
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...
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...
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...
Noise induced hearing loss is a subject of growing
concern. Over the past 15 years, several well-documented
studies have been completed which express the relationships
between industrial noise exposure and damage to normal and
pathological ears. This research has provided knowledge of
considerable importance to developing successful hearing
conservation programs....
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...
This is an interdisciplinary study combining the areas of
Sociology, Religious Studies, and Adult and Community Education.
Drawing from these disciplines, an investigation was made into
the religious and socio-economic variables of development and
their relation to family planning policies in the Muslim world.
The primary focus in this study...
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...
As an increase in Americans seek their leisure experience in
rationalized forms of play, certain symptoms of non-enjoyment, non-flow
achievement are present; i.e., aggression. This relationship between
aggression and rationalized play has widely manifested in university
intramural sports settings. The review of literature provides the
logical development for this relationship...
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 analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
The chopper-stabilized operational amplifier has good low
frequency noise properties. Unfortunately a simple technique for
simulation of the chopper-stabilized operational amplifier has
not been available.
This thesis describes the implementation of a differential
amplifier using chopper stabilization and its circuit modeling
for the SPICE simulation. This circuit has been designed...
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...
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...
