The purpose of this investigation was to evaluate the effects of
a six week residential summer program of differential education for
gifted high school students. It was designed to determine the extent
to which participants in the program were proficient in aspects of
critical and creative thinking, and in the...
A cytogeographical study was made of populations of tetraploid
(n=18) and hexaploid (n=27) Achillea millefolium (Compositae-
Anthemideae) from the Pacific Coast states. There is a complex
distributional pattern, involving overlapping ranges, mixed populations,
migration of one form into areas occuplied by the other,
pentaploid hybrids, and septaploid and octoploid plants....
Biochemical studies of phenylmercuric acetate (PMA) and
mercuric acetate toxicity in rats carried out during this investigation
were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral
ingestion,
(2) the effect on some
soluble enzyme activities and determinations of ²⁰³Hg binding in the
enzyme fractions,...
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...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
Purpose of the Study
In most liberal arts colleges, the majority of students enrolled
are primarily interested in a liberal education. To meet the requirements
of its students, several colleges have introduced a relatively
new program in the sciences; this program is the integrated
science course. This study attempts to...
A fluorescent dye, 1-dimethylaminonaphthalene-5-sulfonyl
chloride (dansyl chloride), was covalently bonded to polylysine. The
dansyl tagged polylysine was complexed to DNA by gradient dialysis.
The polarization and intensity of fluorescence of the dansyl and the
turbidity of the complex were measured as a function of salt concentration
for a variety of...
The purpose of this study was to assist the development of an
improved industrial arts curriculum and laboratory facilities that
reflect the industrial technology. The project attempted to
ascertain which of the process operations of the technology may
become curricular components in the curriculum. In addition, it
attempted to identify...
The purpose of the study was to determine the current status
of provisions being made to provide for appropriate utilization of
the increasing quantities of audiovisual equipment and materials
available in the public schools of Oregon. The ultimate objective of
the study was to identify activities and programs essential to...
Reports of investigations on nucleases in arterial tissue are
few in number. The present study is concerned with the purification
and characterization of an aortic ribonuclease.
An endonuclease (ARNase I) isolated from the bovine aorta has
been purified 4611 fold by means of fractionation with ethanol, acid
extraction, isoionic precipitation,...
