Purpose
The purpose of this study was to investigate the effects of a required
mathematics content course upon prospective elementary school
teachers at Brigham Young University. The investigation consisted of
three major areas: (1) attitudes toward mathematics, (2) basic mathematical
understanding, and (3) the relationship between certain selected
variables.

Knowledge of a compound's degradation pathway is crucial to the assessment of risk at contaminated sites. Pentachlorophenol and its metabolic products can serve as model compounds to study the fate and transport of halogenated aromatic compounds in the environment. Acclimation of anaerobic sewage sludge to pentachlorophenol produced a microbial consortium...
Laboratory experiments and simulated field conditions were
utilized to gain a better understanding of the ecology of the clouded
salamander.
Animals collected in western Oregon were utilized for studies
in habitat selection, where it was shown that there was a significant
pattern of selection of litter types (rock, bark, and...
The purpose of this investigation was to determine if the level
of aspiration procedure consisting of knowledge of results plus goal-setting
possesses a motivational property as reflected in performance
on subject matter criterion instruments above that of knowledge of
results alone in an undergraduate biology course. In addition the
study...
As hardware becomes cheaper and cheaper, there is an
increasing interest in the implementation of distributed control
networks with microcontrollers. Such networks are usually
inexpensive and of high performance.
In this thesis work, a low-cost display control unit for COLAN, a
control-oriented network, is designed. The system is based on...
Nut drop in the filbert is a consequence of the senescence of the
husk. It is possible to accelerate this process by the application of
ethephon (2-chloroethyl)phosphonic acid after the nut has abscised
from the base of the husk. This study is an investigation on the physiological
effects of the...
