This paper is a continuation of William Zell's thesis, A Model of Non-Euclidean Geometry in Three Dimensions. The purpose of that thesis was to show that the axioms of non-Euclidèan geometry are consistent if Euclidean geometry an& hence arithrnetic is consistent. Mr. Zell. discussed the axioms of connection and order...
The primary objective of this study was to develop a prototype
instrument of procedures and criteria to be used by community college
s for self-analysis and evaluation purposes. The study grew out of
the recognized need to assess and improve the effectiveness and pertinence
of community college philosophies, roles and...
Studies were conducted from 1962 to 1966 to investigate the
effectiveness of several practices in manipulating medusahead
(Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated
ecosystems by releasing competition in favor of perennial grasses.
Several herbicide treatments were evaluated for selective
control of medusahead and cheatgrass (Bromus tectorum L. )...
In a search for new therapeutic agents, a series of Mannich bases
derived from the following 2-phenylindolizines were prepared: 2-phenylindolizine, 1, 2-diphenylindolizine, 3-methyl-2-phenylindolizine,
3-ethyl-2-phenylindolizine, and 1-(2-hydroxyethyl)-2-phenylindolizine.
The investigation was based on the speculation that indolizine
analogs of physiologically active indoles might be useful medicinally.
A certain group of indoles, all...
The brine shrimp, Artemia, was used as an experimental
organism to study the effects of ⁶⁰Co gamma irradiation on the reproductive
performance of an animal population. The total reproductive
ability of the brine shrimp was fractionated into various components
and the effects of irradiation on each of these components
was...
A sequence of soils derived from tuffaceous rocks was sampled
on the H. J. Andrews Experimental Forest and adjacent U. S. Plywood
land to determine some genetic and stability relationships. The
less than two micron size fraction from each sample was characterized
by x-ray diffraction with respect to crystalline clay...
