The enclosed thesis presents an algorithm, programmed
in FORTRAN IV, which generates the radii for
the objective of an astronomical refracting telescope.
The results are analyzed by the Trigonometric Ray
Trace, and found to have tolerable amounts of spherical
aberration, chromatic aberration and coma.
This paper presents an exposition of the stochastic models
for the Brownian motion. The results of Einstein and Wiener are
presented, together with the Uhlenbeck-Ornstein process which
gives a more realistic model of the Brownian motion of a particle.
Finally, applying a one-one transformation on the forward
Kolmogorov equation we...
Research was initiated to find a secondary bleach to remove brown discoloration on sulfur dioxide brined sweet cherries. In addition, studies were carried out to determine the effects on texture of not only the secondary bleaches, but also the primary bleach (sulfur dioxide). Three bleaches were found to remove the...
A strain of Aphanizomenon flos-aquae Born. et Flah. has been
introduced into culture and maintained since August of 1964 in completely
defined media. It exhibits the planktonic, colonial flake form
found in nature, and both heterocysts and akinetes are present. The
color and size of the flake and general appearance...
The ecological and silvicultural importance of snowbrush,
Ceanothus velutinus, in the areas west of the summit of the Oregon
Cascades was studied. Particular attention has been given its nitrogen-
fixing ability under both field and greenhouse conditions.
On west slopes of the Oregon Cascades snowbrush occurs above
2, 500 feet...
Experiments are reported which demonstrate that a cobalt deficiency
in R. meliloti results in a decreased cytochrome content of
bacterial cells. It is concluded that the effect of cobalt deficiency
on cytochrome content of Rhizobium cells and on the leghemoglobin
content of nodules possibly may be explained by an effect...
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...
