The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors
as the introduction of new theories, the demands
and needs of our society and the personnel responsible for teaching.
These changes
are reflected in the curriculum as witnessed
by a historical...
Vegetation as a soil-forming factor was studied under forest
transition and grass while attempting to keep other soil forming factors
constant in the western part of the Willamette Valley, Oregon. The
physiographic units consist chiefly of the interior foothills and slopes
formed from an old basaltic flow with some interspersed...
The Risø data were analyzed for variations in the surface roughness
lengths. The method of analysis was tested on the Wangara data
and proved satisfactory at this homogeneous site.
Annual mean surface roughness lengths were determined for
three wind speed categories and three stability categories. The decrease
in surface roughness...
In the spring and summer of 1975 a study was conducted under natural conditions to determine whether wild adult Dermacentor andersoni Stiles would transmit Anaplasma marginale to cattle. The ticks were collected from the range pasture of Squaw Butte Experiment Station where anaplasmosis is enzootic and D. andersoni is indigenous....
Average characteristics of subsidence inversions associated with
the Pacific High have only been documented for areas along the U.S.
West Coast and over the tropical eastern North Pacific Ocean. This
study, which is based on 3414 upper-air soundings for June through
September of 1964 and 1965, shows the average summer...
The thesis examines the applicability of a two-dimensional flow acceleration model to describe a terrain-induced flow perturbation as measured at Yaquina Head on the central Oregon coast. The geometry of Yaquina Head together with the upstream wind values were used in estimating hilltop winds. These estimates compare well with the...
2, 4-Decadienal was autoxidized by subjecting a purified sample to an atmosphere of pure oxygen for 14 hours. A qualitative analysis of the autoxidative degradation products was made utilizing tandem gas chromatography and mass spectrometry. Additional information was obtained from the determination of the melting point of the DNP-hydrazone derivative...
Flavor problems associated with the use of cheddar cheese
whey in the formulation of ice cream and other food products were
investigated. During spray drying of whey, which transforms bulky
liquid whey into an easily transportable and storable powder,
various degrees of off-flavor development may occur depending on
the care...
The effect of clipping and supplemental nitrogen application on
seed production of Linn perennial ryegrass and Merion Kentucky bluegrass
was studied. Clipping and nitrogen treatments did not significantly
affect the seed yield of Linn perennial ryegrass during the 1967
growing season. The seed yield of Merion Kentucky bluegrass was
significantly...
