An important aspect in device technology is the
processing of GaAs to produce highly-resolved etch
patterns on the substrate. This is done typically on the
GaAs(100) surface. Recently, a number of methods, all
using chlorinated vapor reactants, have been applied to
fabrication of GaAs devices. In spite of these
technological...
The purpose of this study was to validate a field
test of cardiorespiratory fitness for men with mental
retardation. The subjects were 19 healthy men with
moderate mental retardation whose mean age was 26 years
with a mean IQ of 48. Each subject underwent a
maximal treadmill test utilizing a...
The effects of erect leaf canopies on enhancing grain yield in wheat is not
understood. The main objective of this study was to understand the effect of leaf
angle on grain yield by comparing randomly derived-lines from crosses of erect
and droopy leaf spring wheats. Nine traits associated with canopy...
The objective of this study was to develop a numerical model for the movement
and fate of chlorinated phenols in groundwater. In the first part, a numerical model for
several different equilibrium and nonequilibrium sorption processes under isothermal
conditions is developed for one-dimensional, steady-state water flow in soil columns.
The...
Kanter (1977) conceptualized five dimensions of the
interdependence between work and family: occupational
subculture, job absorption, time and timing, rewards and
resources, and the emotional climate of work. Each of
these dimensions affects the functioning and satisfaction
of families and marriages. This research examined how
four of these dimensions (occupational...
The purpose of this study was to determine: 1) the ideal
vocational agriculture summer program activities as perceived by
teacher educators and state supervisors nationwide, and 2) if
there were differences in perceptions towards vocational
agriculture summer program activities among selected groups
impacting vocational agriculture programs in the state of...
This study had two purposes. The first purpose was to
determine whether certain aspects of the Japanese language
were reflected in examples of the Japanese cultural
construct of contemporary essays. The second purpose was
to show how these aspects of the Japanese language reflect
the intuitive, non-logical nature of Japanese...
Winters in north-temperate climates impose high
thermogenic demands upon small birds which are met by
seasonal acclimatization. This thesis investigates the
extent and mechanisms of seasonal acclimatization in darkeyed
juncos (Junco hyemalis) inhabiting western Oregon.
Although insulation is significantly increased in
winter, acclimatization is primarily metabolic. Increased
metabolism is required...
The CARS apparatus at OSU was modified to permit studies in the 0-500 cm⁻¹ spectral region. The new low frequency capabilities were then used to study molecular clusters formed in free expansion jets of carbon dioxide. A strong cluster band was observed at 73 cm⁻¹, with a weaker shoulder at...
The National Agricultural Statistical Service (NASS) conducts quarterly surveys for estimation of some primary commodities produced on farms and ranches. The commodities often have highly skewed distributions with a few farms producing very large amounts. NASS uses dual sampling frames comprised of the list frame for efficient stratification and the...
