The low temperature geothermal resource at Klamath Falls,
Oregon is widely used for heating buildings. A common technique
for using this resource consists of a heat exchanger down in the
well inside a casing which extends the full length of the well.
Slots are cut in the casing to allow...
We are concerned here with well-posed problems for the partial differential equation uₜ(x, t) + yMuₜ(x, t) + Lu(x, t) = f(x, t) containing the elliptic differential operator M of order 2m and the differential operator L of order ≤2m. Hilbert space methods are used to formulate and solve an...
Purpose of the Study The purpose of this study was to: (1) develop a model for predicting high school students' occupational choice satisfaction by measuring the impact of vocational education programs on career decisions, and (2) to examine the validity and the efficiency of the model by testing it on...
Major and minor minerals have been separated from
three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin),
and Leedey). Olivine, hypersthene, diopside, feldspar,
troilite, chromite, phosphate minerals, and metallic
minerals were analyzed for major, minor and trace elements
using instrumental neutron activation analysis and radiochemical
neutron activation analysis techniques. Concentrations
df the...
The Pennsylvanian rocks in south-central Idaho and adjacent areas consist of three main facies: a platform facies, a shelf facies, and a marginal basin facies. The platform facies is represented by the Amsden, Quadrant, and Tensleep Formations, in southwestern Montana and western Wyoming, and contain Middle and probably Lower Pennsylvanian...
The objectives for this study were to determine the causes of
slime formation in activated sludge treatment and to recommend
possible control measures. The primary problem was a seasonal
filamentous bulking which was caused by the mold, Geotrichum
candidum. During the winter, mycelial fibers appeared and formed a
free floating...
A system consisting of two d-c generators, one exiting the other,
is controlled with an EAI 690 hybrid computer in an on-line operation.
The hybrid computer works as a predictive controller with an on-off
actuating signal. A fast-time, second-order model is used to determine
the switching time, and a small...
The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn,
Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61
individual chondrules (0.1-100 mg) separated from five Allende (C3)
meteoritic fragments ( 25g). Ti and V have been determined in 18
of these chondrules, and...
This study, dealing with the concept of career education, was
undertaken to:
1) develop a multi-media career education component for Phase I
of the undergraduate teacher education program at Oregon State
University.
2) measure the effect of that component on selected students.
3) compare their responses with students who had...
