The present investigation was designed to test two major hypotheses
and five sub-hypotheses. The two major hypotheses were:
(1) Parental models influence the shaping of children's responses to
frustration, and (2) There is a positive relation between parental
consistency in responses to frustration and children's imitation of
parental responses. Three...
Statistical data from breeding experiments suggested that a
reciprocal chromosomal translocation had spontaneously occurred in
a line of S. C. White Leghorn fowl. Approximately 50% of the
embryos from matings between suspected translocation heterozygotes
and normal birds died early during incubation. In an effort
to obtain cytological proof of this...
At liquid nitrogen temperature the spectra of sublimed
films of NH₄NCS, both as phase I (the usual form stable at
room temperature) and phase II (the low temperature form),
exhibit detail usually reserved for gases at low pressures.
In both phases the symmetry of ammonium ion has degenerated
from tetrahedral...
One purpose of this study was to evaluate three commercial
detergents by comparing their removals at 70 and 120°F. of palmitic
acid and clay components of a simulated natural soil which had been
applied to wool yarns by immersion and abrasion methods. These
detergents were a built soap and two...
The central purpose of this comparison was to determine the
congruence or difference between two teaching techniques, the television
method and the conventional lecture method as used in teaching
General Hygiene on the freshman college level at Oregon State University.
Sub-problems associated with this study were, (a) the development
of...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
To learn more about the role β-galactosidase plays in rate of
acid production in milk by lactic acid bacteria, several lactobacilli
were examined for this enzyme. Cells from different species were
grown in lactose broth to induce β-galactosidase activity. The specific
activities of whole, solvent treated cells, and of cell-free...
