The purpose of this study was to analyze and describe
the opinions and characteristics of black students enrolled
in Portland Community College.
Data were obtained through a random sampling of two
groups of subjects who were invited to participate in the
study as follows: (1) Black subjects were 109 students...
Spatial, diel and seasonal variations in dissolved oxygen and
temperature were measured in Triangle Lake, Oregon. Spatial dissolved
oxygen and temperature variations measured in the stratified
lake are presented to illustrate the horizontal uniformity of the lake
and to demonstrate the applicability of the one dimensional assumption
for sampling and...
The Purposes of the Study
The primary purpose of this study was to identify common professional
education competencies needed by public school district
vocational education leaders. Other purposes were to (1) determine
if significant differences existed in vocational education leadership
competencies among respondents as categorized by state, type of
position...
The purpose of the study was to analyze the effects of teaching
elementary and secondary students the Gallagher Topic Classification
System as a technique for constructing and analyzing questions.
The subjects for the study were the students of three groups of
randomly selected teachers from Coos and Douglas Counties of...
When the ambient temperature drops, air-source heat
pumps deliver less heating per unit of power input and
usually cannot provide for the heating load. Therefore,
dual-source heat pumps can offer an attractive alternative.
In the context of this work, a dual-source heat pump
operates as an air-source unit under normal...
The foundation upon which any cooperative rests is the economic need for it as a business enterprise. The existence of such a need cannot by itself provide the basis for a thriving cooperative. Not only mus.t the need exist, but the members or the promoters must through realistic and diligent...
A simulation method using a hybrid computer is developed in
this dissertation to enhance the study of wind-driven ocean circulation.
The simulation is based on the mathematical model developed by
Ekman. Pure digital simulation is not economical due to excessive
computer time required for the solution of the partial differential...
Muitiregion annular geometry is a basic feature of energy removal
systems ranging from advanced heat exchangers to fission reactor fuel
rods. For the symmetric cases, the heat conduction through annular regions
is well defined. However, for a shift of an annular region, analysis
of the system must be made in...
