In this thesis the author extends the standard techniques of differential geometry to the case of distributional (in the sense of Schwartz) pseudoriemannian structures. A new definition of flows for distributional vector fields is developed using generalized paths which are essentially nonlinear-distributional measures, and an existence theorem is proved when...
Subterranean clover (Trifolium subterraneum L.) seed production
practices in Oregon are different from those in Australia.
There, seed is produced on fields which are managed primarily for
forage. In Oregon, seed fields are managed for seed as the primary
product and forage is of secondary concern.
Some sheep grazing is...
Tests were carried on in growth chambers and in the field to
determine if the harvest of daylength-sensitive long-day cereals
grown during the winter in Arizona could be hastened 30 days by the
use of night interruption.
Two durum lines which were near-isogenic for sensitivity to
daylength were used throughout...
Storage of water for water quality control is one of the alternative
means of achieving water quality objectives. Authorities in
the field of water quality management disagree regarding the use of
precious water for the dilution of wastes.
The costs of achieving water quality objectives by treatment
of wastes at...
The purpose of this study was to determine the need
for mathematics inservice training for untrained and
trained teachers in K-7 rural schools in Manicaland,
Zimbabwe. The auxiliary teachers do not have any
professional preparation before entry into the teaching
profession. The study sought to determine the mathematics
areas needed...
A method was developed for converting the food producing capabilities
of Oregon's soils to numerical data from which state and county
carrying capacities for human populations could be calculated. Another
method was developed for converting the needs for housing and related
support construction to numerical data which would consume cultivated...
