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...
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...
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...
