Geophysical data collected in 1975 and 1976 reveal major
crustal and tectonic elements of the continental margin of southern
Baja California. Gravity, magnetic, seismic reflection and bathymetric data show seaward extension of the islands enclosing Magdalena
and Almejas Bays. A seismic reflection profile, oriented
approximately normal to the trend of...
An inelastic scattering experiment was done in which 17-MeV
protons from the Oregon State University cyclotron were scattered
from ¹⁴N
and ¹⁵N gas targets. Angular distributions are shown for
the ground, 6.32-, 7.56-, 8.31-, and 8.57 -MeV states and the 5.3- and
7.2-MeV unresolved doublets of ¹⁵N, and for the...
Diffusion of short chain n-alkanes was found to be faster in the
polydimethylsilicone elastomer SE-30 than in the polydimethylsilicone
oil SF-96-2000. The opposite was true for the longer chain n-alkanes
suggesting that choice of stationary phase for gas chromatography
would depend on the chain length of sample components. The dependence...
Studies were conducted in 1969 and 1970 to evaluate the
effectiveness of an experimental herbicide, SD 30053 (alanine,
N-benzoyl-N-(3, 4-dichlorophenyl)-, ethyl ester), for wild oat
(Avena fatua L.) control in winter cereals.
The 1969 field studies showed that postemergence applications
of SD 30053 were effective in controlling wild oats. Wild...
The study on a p-n junction gallium arsenide avalanche photodiode
is reported. The procedures of the fabrication of the diodes
and the measurement of the device performance in terms of photomultiplication
factors are described. The photodiode is mesa type
with an active diameter of 60 microns, and the junction depth...
Gravity, magnetic and seismic data indicate that the oceanic
crust is 9.7 km thick west of the Continental Borderland. The top
of the mantle is about 12 km deep under the Borderland, and deepens
to 27 km beneath the Peninsular Ranges of Baja California. The
mantle is about 20 km...
Greenhouse and growth chamber experiments were conducted with
the following objectives: (a) to study the effects of N-1-naphthylphthalamic
acid (naptalam) on shoot and tuber production, rhizome transformation,
and growth of yellow nutsedge (Cyperus esculentus L.) plants;
(b) to study the effects of N-phosphonomethyl glycine (glyphosate) on
nutsedge plants at different...
The traditional Hicks-Allen theory was presented and modified
by (1) formulating the consumer's budget constraint with a weak
inequality, (2) deriving the Slutsky equation in matrix notation and
(3) demonstrating that the income and substitution effects could be
derived directly from the partial derivatives of the consumer's
demand functions. Two...
The asymptotic boundary layer problem involving an axial
incompressible Newtonian fluid flow past a circular cylinder parallel
to its axis was investigated by Stewartson (1955). He addressed hiself
primarily to the Mangler's (1948) derivation, namely, the
character of the boundary layer on a circular cylinder is equivalent to
that on...
The experiments in this thesis are reported as two journal
articles. The first article. The effect of rootstock and scion on
above- and below-graft leaf mineral nutrient content of sweet cherry,
is a field sampling experiment dealing with the effect of Stockton-
Morello and F 12-1 mazzard rootstocks on 'Royal...
The length of time that atmospheric pollutants released from low-level
sources in the midwestern United States can expect to remain in
the atmosphere is discussed. The pollution is assumed to be removed
from the atmosphere by dry deposition and precipitation scavenging.
Layer-average trajectories originating from Kansas City, Missouri are
used...
An introduction to the generalized measures of deformation-
rates involving not only velocity gradients but also
acceleration gradients is given and constitutive equations
using these measures have been discussed. These new constitutive
equations are then used to study torsional
flows of viscoelastic fluids between two infinite parallel
planes. In order...
Direct digital control is becoming quite common in the control
of industrial processes. However, due to the relatively high accuracy
of both analog and conventional digital systems for controlling the
speed of a dc motor, there has been a reluctance to try DDC for
this purpose. This thesis describes a...
We investigate in this thesis, the problem of stability
of thermo-viscoelastic fluid flow between rotating
coaxial cylinders. By using the thermo-viscoelastic
constitutive equations given by Eringen, we reduce the
equations of motion into a form suitable for stability
analysis. The course of reduction which we follow yields
some interesting intermediate...
