The single-cross and most F₂ progenies of 19 genotypes of
tall fescue (Festuca arundinacea, Schreb. ) were used to study the
breeding behavior of forage yield. Parental genotypes were selected
for high self-sterility, high chromogen and high crude protein. These
were studied in two groups of nine intermediate and ten...
A liquid sulfur dioxide battery, such as K/KCl SbCl₅ (0.25
molar) + IBr₃ (15 %wt) + SO₂ (1)/carbon matrix is shown to have an
open circuit voltage greater than 3.70 volts and an initial voltage of
3.15 volts, decreasing to 2.40 volts in 10 minutes at a current density
of...
Some forms of bacterial respiration do not involve molecular
oxygen but instead utilize other hydrogen acceptors for oxidation
of the substrate. Various organic and inorganic acceptors may be
used. In the present study, the inorganic radicals, nitrate and
nitrite, were investigated. Preliminary evidence indicated that
nitrate and oxygen are able...
Because the life processes of the plant are related in a complex
way to the balance between the water demand of the atmosphere and
the water availability to the plant root, an exploration of the dynamic
status of water in the plant is very important. The stomata constitute
the main...
Cardicola alseae is a blood dwelling trematode found in the
fishes Salmo clarki henshawi and Salmo gairdneri gairdneri. Eggs
which were ovoid in shape and non-operculate left the adult and passed
to the gill capillaries of the secondary lamellae. The miracidium was
ovoid, 0.070 mm. long by 0.052 mm. wide,...
A method of calculating the normal vibrations of polymer molecules
is presented in detail. The method is based on that used by
Schachtschneider and Snyder in their analysis of polypropylene but
has not heretofore been published. The factoring of the infinite matrix
and reduction to the coordinates of the unit...
A biochemical study of aging was conducted on mitochondria
from the embryo axes of germinating new and old soybean seeds.
Differential phosphorylative efficiency, an average P/O ratio of 3.03
of the new material compared to 1.44 of the old, was obtained when
all the co-factors and substrate were provided. No...
Prevailing concepts relating to the non-enzymatic gaseous
loss of nitrite from soil are thought to be inadequate as regards
to the mechanisms involved. The conventional explanation for
nitric oxide formation i.e., the acid decomposition of nitrite,
is held to be insufficient in substrates of only mild or slight
acidity. A...
The incitant of Verticillium wilt of peppermint (Verticillium
dahliae Kleb.) causes disease symptoms only in the genera Mentha
(the mints) and Monarda. This fungus is unable to grow saprophytically
through natural soil. V. dahliae survives in soil by colonizing
and forming microsclerotia in susceptible plants, living root tissue
of many...
This investigation was undertaken to characterize and evaluate
the forage production and utilization of the successional vegetation
of the mixed conifer forest.
Field studies were carried out during the summers of 1962
through 1964 at the Eastern Oregon Experiment Station Hall Ranch
which is located 12 miles southeast of Union,...
The effect of a pulse produced by an acoustic or electromagnetic
line source oriented parallel to the edge of a perfectly conducting
half plane is considered. The Green's functions for the modified
Helmholtz equation are found by solving for the Green's functions
for a cylinder of sectorial cross-section, then allowing...
Preparation of a cytochrome c-cytochrome oxidase complex
was achieved, using crystalline beef cytochrome c and purified
cytochrome oxidase from beef heart muscle, or from the
Keilin-Hartree preparation. Succinate oxidase was reconstituted
with the complex.
A mixture of cytochrome oxidase, solubilized with nonionic
detergent, and excess cytochrome c was exposed to...
Although much information is available on lipids in serum and
red cells, only limited data have been reported for white cells and
platelets. In a recent investigation in this laboratory, the concentrations
of cholesterol in the several blood fractions were compared.
The high amounts of cholesterol found in white cell-platelet...
Three realms of deposition, Marine, Fluviatile, and Marine-
Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of
sediment texture and mineralogy. The Marine Realm extends 1.5
miles into the entrance of the estuary and is typified by normal
marine salinity and vigorous tidal action. Sediments of this realm...
A series of four animal experiments utilizing 129 pigs
and associated laboratory studies was conducted to study the causes
of the lowered performance on high barley rations fed to swine. Previous
work at this Station has shown barley to have a value of 80-85
percent of corn for swine, and...
The purpose of this study was to study in some detail
host factors which influence the population dynamics of
bark beetle. The dissertation objectives were to ascertain
the applicability of utilizing osmotic pressure
values and relative turgidity values of phloem tissue as
indicators which reflect upon the physiological profile
of...
