A method for measuring the spark-shower radiance of metals
when abraded on an abrasive grinding wheel was developed for
evaluating their sparking tendency. One hundred metals were tested
and rated relative to commercially pure iron. The radiance was
measured in units of energy per solid angle per area of the...
The purpose of this study was to investigate the relationship
between the weaving performance and the visual perception abilities
of primary school children. The sample population consisted of 50
first-graders, 26 boys and 24 girls.
A measure was developed to test weaving performance; the
children participated in a weaving lesson...
The purpose of this descriptive research was twofold: 1) to
determine the expressed concerns, feelings, and needs of a selected
group of expectant fathers; and 2) to categorize those expressed
concerns, feelings, and needs into broad areas and to develop a
priority listing of those items as a basis for...
This thesis documents a method of proving that Turing machines
work for every case, if the construction of the Turing machine is
known. Mathematical Induction is used to construct the proof that the
Turing machine for binary addition will work in every well-formed case
of the input that it receives....
Examination of polished sections of manganese micronodules
from metalliferous sediments from the Bauer Deep reveals sequences
of ferromanganese deposition which are consistent for micronodules
from a single sediment sample and imply a common depositional
history for members of such assemblages. The relatively simple
'stratigraphy' of manganese micronodules, as compared to...
Rhyacophila is one of the largest genera of caddisflies, containing
about 465 species. Approximately 100 species are found in
North America with 83 occurring in the west, The larvae of 24
western North American species are associated for the first time,
making a total of 38 species for which larvae...
Cable logging systems are being applied frequently in thinning young-growth forests, but the dynamics of these systems are relatively unknown. This study is part of a research project to develop aerial logging systems for thinning and to analyze them for economic, silvicultural, and environmental implications. The objectives of my study...
