There is a lack of available information concerning availability,
usability and utilization of school-owned land in western Oregon,
southwestern Washington and northwestern California. It would be
helpful to know if land is available for agricultural use, how it is used,
and ways that it can be used to give experience...
The emergence of a new generation of remote sensing and geopositioning technologies, as well as increased capabilities in image processing, computing, and inferential techniques, have enabled the development and implementation of increasingly efficient and cost-effective multilevel sampling designs for forest inventory. In this paper, we (i) describe the conceptual basis...
The purpose of this study is to review Pennsylvania's
use of paper money through two distinct periods: the first
seven years of currency issues starting in 1723 and
concluding in 1730, and the second period encompassed by
the French and Indian War in 1755-63. They represent two
significant periods affecting...
In 1962 a large amount of data was collected in an effort to
establish the existence of subsurface ocean currents off the coast of
Oregon. The presence of several phenomena, including tides and
measurement errors not directly associated with the hypothetical
currents, complicates the interpretation of the data and the...
The purpose of this study was to provide information
pertaining to performance levels of Dvorak keyboard operators
through retraining. More specifically, the purposes of
this study were:
1. To compare operator performance rates on the
Dvorak keyboard with operator performance
rates on the Qwerty keyboard.
2. To determine whether keyboard...
The presence in rat liver microsomes of an enzyme system
which demethylates N-methylhydrazines and azo compounds to formaldehyde
has been reported. Some of the compounds found to be
substrates were monomethylhydrazine, N-isopropyl-α-(2-methylhydrazino)-
p-toluamide and the azo derivative of the latter hydrazine. This
enzyme can be classified as a mixed function...
The purpose of this study was to assist the development of an
improved industrial arts curriculum and laboratory facilities that
reflect the industrial technology. The project attempted to
ascertain which of the process operations of the technology may
become curricular components in the curriculum. In addition, it
attempted to identify...
A rheostat is an adjustable resistor so constructed that its resistance may be changed without opening the circuit in which it may be connected. Conventional rheostats are adjusted mechanically. This thesis presents a method of adjusting resistance electrically by varying the light intensity incident on the surface of a photoconductive...
The purposes of the study were to determine the relationship which existed between higher cognitive level question wait-time range and student achievement, and whether students perceived biology student teachers who used a 1-4 second wait-time range as being either more or less effective than biology student teachers who used a...
An experimental investigation has been made of the effect of
vibration on heat transfer from a cylinder in crossflow. The
cylinder used was 3/16-inch in diameter and was sinusoidally
oscillated in the vertical direction by a mechanical drive mechanism
while immersed in an open water channel. Nominal amplitude
ratios, a/d,...
