Manganese has been known to be essential for photosynthesis
for almost 30 years. Subsequent experimentation
indicated a definite function for manganese in oxygen evolution.
However, the mode of action of manganese and
further localization of its...

The reaction of certain purin-8-ols with phosphorus
oxychloride and N,N-diethylaniline are described.
9-Amino-6-chloropurin-8-ol monohydrate reacted with
phosphorus oxychloride and N, N-diethylaniline to yield
the phosphorus oxychloride adduct....

Four surface and three subsurface horizons of agriculturally
important Oregon soils were exposed to excessive volumes of anhydrous
ammonia and reequilibrated with the atmosphere for several
time periods prior to extraction with water. The carbon...

The examination in some detail of the relationships between
air quality and the thermal structure of the lowest layers of the atmosphere
constituted the primary objective of this thesis. Data for
the study were assembled during April-June 1965 at...

This study was undertaken to determine the role Leuconostoc
citrovorum may play in carbon dioxide production in milk. The
ability of L. citrovorum strains to produce gas was studied by two
methods. A qualitative method used visual measurement of...

In this study subcutaneous, inter- and intramuscular fats from 42
Hereford steers were analyzed for their fatty acid composition using
gas-liquid chromatography. The same tissues were analyzed from one
pair each of identical twins of Angus and...

A soil’s capillarity, associated with the parameter sorptivity, is a dominant control on
infiltration, particularly at the onset of rainfall or irrigation. Many mathematical models
used to estimate sorptivity are only valid for dry soils. This...

The development of a least squares model for the
determination of compliance constants from various combinations
of vibration frequency, mean square amplitudes
of vibration and centrifugal distortion data is discussed.
The resultant model is...

In freshwater the crayfish, Pacifasticus leniusculus, maintains
sodium balance by absorbing sodium against a large concentration
gradient. The site of uptake is the gills. The rate of uptake is
regulated and can be increased by depleting the...

A design for an agricultural airplane is developed and evaluated,
A biplane configuration was adopted since it provides better maneuverability
and stall characteristics than a monoplane of comparable
size and design simplicity. The airplane,...

A comparison of the various endocrine glands, in addition to
other anatomical measurements, was made on 19 normal and 21
dwarf 2-3-month-old females and 20 normal and 20 dwarf 7-13-month-old females of the White Leghorn breed. At both ages,...

Leptarctia californiae (Walker) was studied on clear and semi-forested southern slopes in the Coast Range Mountains of Benton County,
Oregon. The spring of 1965 had an unusually long warm period (21 days)
resulting in adult emergence approximately...

Experiments were designed to reveal the accuracy and precision of
four types of automatic sampler prototypes after initial testing indicated
that the single tube vibrator sampler was not drawing a complete
cross section of the seed flow in a...

A study was conducted to determine what effects the type of
pollutants, storage conditions, storage time, and method of sample
conditioning have on the reported weight of an air pollutant collected
by filtration. Samples were collected from a...

The purpose of this study was to isolate and characterize any
segregants of the heterogenotes formed from sexduction by an F'
donor. Following the mating of F' W4520, carrying an F' gal₁⁺
gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a...

Concern regarding the large numbers of personal bankruptcies
in Oregon prompted this study. Although information was available
from a few studies in other parts of the United States, none was
available for Oregon. Very little data has been...

A comparative study was made on the effect of urea denaturation
of bovine serum albumin (BSA), polyglycyl BSA and poly-L-phenylalanyl
BSA. The denaturation process was followed by ultraviolet
spectrophotometry and optical rotation.
A blue shift in...

Temporal and spatial patterns of daytime cloudiness in the
Willamette Valley of Oregon were studied by utilizing monthly and
daily sky cover data published by the U. S. Weather Bureau for the
Portland, Salem, and Eugene stations. The 15-year...

The purpose of this research was to study the effect of capillary
tube dimensions on the apparent viscosity of an unstable dispersion
of two immiscible liquids. The study was limited to laminar
flow at a constant temperature.
The dispersions were...
