The purpose of this study was to make a preliminary
investigation of the productivity of some of the soils
within the Willamette catena under different systems of
soil management. The study was carried out at four experimental
sites near Corvallis, Oregon, during the 1962 growing
season. The soil at each...
Subterranean clover was grown in nutrient solution and S
deficient Steiwer soil in the greenhouse. Plants were harvested at
15, 30, 45 and 60 days after emergence.
When subterranean clover was grown in nutrient solution significant
yield response to each increment of added sulfate (SO₄-S)
occurred in 15, 30, 45...
A knowledge of the time rates for intermediate reactions
during the photolysis of nitrogen dioxide enables one to deduce the
possible intermediate reactions which are responsible. An experiment has been devised and constructed which will measure the time
rates for photochemical reactions occurring in ranges of one micro
second to...
This thesis contains a collection of properties of the greatest integer part function which were obtained by an extensive literature search. A few original properties are stated and proved and some of the properties which were found unproved in the literature are proved.
Purpose of the Study
The basic purpose of this study was to examine the attitudes and
opinions of community college personnel toward faculty involvement
in policy formulation.
Procedures
The statistical and subjective data for this study were obtained
from two major sources. (1) A statistical questionnaire was
developed to identify...

Bdellovibrio bacteriovorus is a small parasitic bacterium present
in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative
bacteria, an important role in soil ecology has been suggested
for this organism. A study of effects of herbicides upon
Bdellovibrio might consequently be of considerable value.
In this study...
Acetaldehyde is known to be responsible for the green
or yogurt-like flavor defect of lactic cultures. This study was undertaken
to extend the knowledge of acetaldehyde production and utilization
by microorganisms normally found in mixed-strain butter cultures.
It is anticipated that the resulting information will contribute
to a more thorough...
This study was designed to identify and describe home management
tasks, perceived managerial competency, and related social,
psychological, and economic consequences for a sample of retired
couples.
Managerial tasks were defined as essential, periodic activities
which (1) sustain the living patterns of a person or family in a common
household,...
The purposes of this investigation were twofold:
1. To determine important criteria for making a selection of
course content in general biology.
2. To ascertain what should be the content emphasis in
biology for the purposes of general education at the freshman
college level.
The literature pertinent to the problem...
1. Distribution: A general map of distribution is given in the introduction, showing the range of the genus as a whole. A second, composite map, provides collection localities for the three species studied. Other maps indicate sites of collection for each individual species, including nests of P. longicaudus and P....
