This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
The ultrastructure of the oviduct and the hormonal induced
alterations in the cellular organelles of prepubertal and ovariectomized
rabbits have been studied with electron-microscopic histochemical
methods.
The pseudostratified epithelium of the oviduct in prepubertal
rabbits contained both ciliated and secretory cells. The secretory
cells showed apocrine projections filled with electron-dense...
Two methods of separating sugars and acids of Bartlett pears
were compared to decide upon a working method for later studies
involving identification and quantitation of sugars and acids during
ripening of pears and in the production and storage of pear concentrate.
The first method involved precipitation of acids with...
The anchor-last mooring procedure is investigated in order to determine the transient forces in the mooring line and the velocities of the anchor. Transient forces were determined and the results showed that no severe snap loads occurred for the cases investigated. In addition, it was found that the vertical velocity...

There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
A major problem of this study was to assess a model for predicting attitudes and behavior of vocational teacher trainees toward handicapped learners. A second problem was to determine whether or not both attitudes and behavior of vocational teacher trainees toward handicapped learners could be changed. The sample for this...
The purpose of this study was to determine a student's attitudes toward
business, his level of occupational aspiration, and the degree of correlation
between them. Two questionnaires were used: Student Attitudes Toward Business
and Level of Occupational Aspiration.
The business attitude questionnaire elicited student reactions to 87
business-related statements. The...
Two experiments were conducted to determine the effects of
moisture stress on physiological changes that occur during the vegetative
and reproductive stages of the wheat (Triticum aestivum L.)
plant, and to relate these effects to seed yield, quality and performance.
In a field experiment, different levels of moisture stress were...
Hop varieties were compared under field and greenhouse conditions to determine their relative susceptibility to the twospotted spider mite, Tetranychus urticac Koch. A fertility schedule was prepared for mites on resistant and susceptible varieties, and tests were conducted to compare sex ratio, oviposition rate, survival rate, and developmental rate of...
Three kkeeyy variables are examined to determine their influence on
the process of community planning at Corvallis, Oregon. These are
(1) the setting of priorities, (2) organization and (3) external
reference. Interactions of goals program participants were recorded
as the community responded to comply with Oregon Senate Bill #100's
requirement...
At weights of 81.5-90.5 kg, 187 prepuberal crossbred gilts were
subjected to specific environmental stimuli, for up to 17 days, to
determine which stimuli or combinations of various ones would initiate
onset of estrus in prepuberal gilts. The stimuli used were:
movement to new building, mixing or non-mixing of gilts,...
This study examines two major issues: (1) to what extent have the
conditions at non-reservation Indian boarding schools, as described by
the Meriam Report of 1928, been in evidence from the beginning?; and
(2) to what extent have these conditions improved since 1928?
The conditions examined are: (1) General Conditions...
In 1906, applying Charles Darwin's evolutionary theories to the human race, Sir Francis Galton introduced the concept of eugenics, "the science of the improvement of the human race by better breeding." The rediscovery in 1900 of Mendel's laws of genetic inheritance and an upsurge in hereditarian thought set the stage...
The study was devoted to formulating answers to the following
questions:
1. What factors did students report to be influential in their
choice of a community college major ?
2. What factors influenced students in the selection of a
community college to attend?
3. What factors influenced students to continue...
This investigation was concerned with the work values of tenth
grade girls and their relationship to the girls' aspirations and expectations
for future education and marriage-career roles.
The instrument employed for the value measurement was the
Work Values Inventory of Super (1968). An original questionnaire was
developed by the researcher...
Sodium ligninsulfonate, a water soluble wide-range molecular
weight polymeric by-product of the paper pulping industry, is
added as waste effluent to water ways or burned, causing extreme
pollution. The polymer is highly resistant to biodegradation. Therefore,
modification of the structure to a more readily biodegradable
form would be desirable, to...
Purpose of the Study
The purpose of the study was to determine whether there were
significant differences in students' career maturity as a result of
exposure to the concepts of career education. The study evaluated the
relative effectiveness of a developing comprehensive career education
project to help students attain increased...
Jean Baptiste Lamarck (1744-1829) is considered here in the
context of the Enlightenment effort to develop a science of man. His
Philosophie zoologique (1809) and the Systeme analytique (1820) are
the two principal relevant works examined in depth to discover how
he meant to base a science of man on...
Purpose of the Study The purpose of this study was to: (1) develop a model for predicting high school students' occupational choice satisfaction by measuring the impact of vocational education programs on career decisions, and (2) to examine the validity and the efficiency of the model by testing it on...
This thesis research consists of an investigation of the human
influences on wildlife in Belize. The study was accomplished by the
collection and analysis of data with respect to land use, habitat
characteristics, and wildlife status in Belize. Requirements and
status of many species are tabulated in order to give...

The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
