The competition or rivalry for the use of water resources
among economic sectors of the Pacific Northwest and among geographical
regions of the western United States has intensified in recent
years. This rivalry and the long run prospects for water shortages
have increased the demand for research concerning the productivity...
The study evaluates performances of three multiple time series
(MTS) forecasting methods; investigates possible improvements in
MTS forecasting operations, and proposes a multiple time series
based forecasting system. Time series considered are finite,
linear, covariance stationary, and discrete.
Specific objectives for the thesis were: (a) conducting comparative
studies of MTS...
Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis.
These inbred lines originated from three random-bred stocks: OR,
TX and CD. The experiment was conducted as a completely randomized
design. Experimental material consisted of parental lines and F₁ populations maintained...
The hypotheses of this study stated the following:
Interaction with the computer game will significantly
increase the class means in: (1) mathematical
achievement, (2) attitudes toward mathematics, and (3)
graphing ability in high school advanced algebra.
ALGEBRA ARCADE is a computerized simulation game
played on a coordinate grid. One can...
The effects of erect leaf canopies on enhancing grain yield in wheat is not
understood. The main objective of this study was to understand the effect of leaf
angle on grain yield by comparing randomly derived-lines from crosses of erect
and droopy leaf spring wheats. Nine traits associated with canopy...
Three distinct studies using an ethidium bromidedigitonin
fluorometric assay were conducted to determine
if the fertilizing ability of individually caged broiler
breeder males (BBM) could be enchanced by nutrition,
breeding and semen extender viscosity.
The first study evaluated the effects on the
spermatozoal quality of BBM by feeding corn-soybean meal...
To understand the influence of selective harvesting on
the adaptive capacity of fish populations in changing
environments, a computer simulation model was developed. In
the model, hypothetical populations were composed of five
different life histories, which were genetically determined.
Each life history type had its own rate of survival and...
