To remain competitive in the international marketplace,
soft white wheat cultivars grown in the Pacific Northwest
must have consistent and predictable flour properties
including kernel texture. As a consequence, there is a need
to develop wheat cultivars for specific end uses. Wheat
cultivars with very soft kernels are used largely...
Measuring the source and magnitude of components of variation has important
applications in industrial, environmental and biological studies. This thesis considers
the problem of constructing confidence intervals for variance components in Gaussian
mixed linear models. A number of methods based on the usual ANOVA mean squares
have been proposed for...
There was a linear relationship of [alpha]-amylase activity
from 2 to 12 hours incubation in both freeze-dried and fresh
'd'Anjou' pear fruit tissue. Activity was greater, however,
in fresh as compared with freeze-dried tissues. [alpha]-Amylase
activity from both types of samples was not detected until
60 minutes incubation. After 90...
The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze
the partition of energy and distribution of water over land surfaces. The combination of
remotely sensed data and ground instrument networks over the large-scale in situ experiment
allowed investigation of spatial and temporal variation of such hydrologic parameters as the...
The objective of this research project was to identify the limitations associated
with schedule-based Material Requirements Planning (SBMRP) and to
present a knowledge-based expert system (KBES) approach to solve these problems.
In SBMRP, the basic strategy is to use backward or forward scheduling
based on an arbitrary dispatching rule, such...
In site index studies, the hypothesis that height
growth of most conifers is independent of stand density
is commonly accepted. However, some studies have shown
height growth to be influenced by density particularly
on medium to poor sites.
In this study two locations representing a high
quality site (Hoskins area,...
In recent years the conversion of agricultural lands to more
intensive non-rural land uses has become a focus of increasing public
awareness and concern. The growing attention to farmland conversion
is manifested in increasing public policies and legilsation to protect
agricultural and forestry land uses. Nevertheless, our understanding
of the...
The toxicity of chlorobenzene (CB) was investigated in rainbow
trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil)
and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously
flowing system for 15 and 30 days.
In the acute study, overt toxicity...
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...
