Data collected by personnel of the Geophysics Group at Oregon State
University and the Instituto Oceanografico of the Direccion General dé
Oceanografia are used to construct a free-air anomaly map for the central
part of the Pacific continental margin of Mexico, which shows the gravity
expression of major structural features...
Geophysical surveys in the Gulf of California provided
the data to construct contour maps of bathymetry, free-air
anomalies and total field magnetic anomalies for the area
north of 27° N. Major faults such as the Ballenas-
Salsipuedes, Tiburón, Guaymas, and the South Cerro Prieto
are clearly observable on these maps....
A study was conducted to determine the effect of dietary protein on
performance of commercial New Zealand White rabbits.
In Part I of this study, three levels of crude protein (17.5, 19
and 20.5%) were fed to lactating does and their offspring during a 12
month period. Total rabbits born...
The displacement of the free liquid surface in geothermal and
hydrologic reservoirs is an important capacitance factor. An
iterative approach to determining the drawdown of the free liquid
surface for a single sink region in a homogeneous, isotropic, Darcy-type
porous mediums is discussed. The iterative approach involves a
stepwise adjustment...
Using gravity, magnetic, bathymetric and seismic
refraction data, I have constructed a geophysical cross-section
of the central part of the northern Gulf of California. The
section exhibits a crustal thickness of 18 km and features an
anomalous block of high density lower basement (3.15 g/cm³)
which probably resulted from rifting...
A great potential for increasing upland rice production exists in
the savanna soils of Colombia. These vast areas are currently
underutilized. However, they have good soil structure, flat
topography, coupled with sufficient and well distributed rainfall,
making savanna soils ideal for upland rice cropping system. The major
constraints to upland...
Several studies have been conducted to examine the
utilization of non-protein nitrogen by the New Zealand
White rabbit.
Soybean meal (SBM) or urea added to a low protein (13%
CP) diet and a positive control diet were fed to does and
their offspring during a nine month experiment. Urea and...
An evaluation was made on the nutritive value of tropical forages
and by-product feeds for rabbit production. Digestibility of nutrient
fractions, feed preferences, growth, combination of forages, supplementation
of micro and macro nutrients and/or effects of drying temperature
on the quality of four groups of forages, namely woody legumes
(WL),...
Anomaly timescales for the last 90 million years, derived from
marine magnetic profiles and published prior to mid-1979, are summarized,
illustrated for comparison, and critically reviewed. A revised timescale
is constructed using calibration points which fix the ages of anomalies
2.3', 5.5, 24, and 29. An equation is presented for...
