The principles of continuum mechanics provide a consistent
framework for the derivation of mathematical statements describing
transport of water and solute, and growth in plant tissue. These
derivations are based upon the explicit consideration of the tissue as
a mathematical continuum composed of a cell wall matrix, water, and
solute...
Spatial flux profiles were calculated in idealized,
optically-thin ( 1 mfp) cell systems using integral
transport theory. Numerical accuracy improvement and
convergence efficiency in computing these spatial flux
profiles was the primary concern. Toward these ends, kernel
volume-averaging techniques for curvilinear cell systems, a
reflective angular-dependent edge source boundary condition...
Persistent infections with infectious pancreatic necrosis virus
(IPNV) were established in two salmonid cell lines and in live brook
trout. Virus inocula containing high concentrations of defective
interfering IPNV enhanced but were not a requirement for the establishment
of persistent infections in cell lines derived from steelhead
trout (STE-137) and...
In 1976 and 1977 I examined three broad problems associated with the recruitment of young mallards, Anas platyrhynchos, in the Prairie Pothole Region of North Dakota. The three problems studied were: the effects of interspecific nest parasitism on production; the chronology and magnitude of total-brood loss during the brood-rearing period;...
The purpose of this research was to investigate the relationship
of internality and structural variables such as sex, socio-economic
status, and academic achievement to the extensiveness and effectiveness
of vocational exploratory behavior during college.
The sample utilized in this study consisted of 108 male and
female seniors who were in...
The major objective of this study was to determine why certain
winter wheat cultivars, when hybridized, will produce a greater proportion
of desirable plants in subsequent, segregating generations.
Three winter wheat parents were chosen as the experimental material,
based on their known performance as parents. Yamhill and
Pullman Selection 101...
The purpose of this study was to investigate the effectiveness of a guidance-based career exploratory program related to skilled trades and technical occupations for internal-external locus of control middle school females in Murray, Kentucky. The problem was to determine the change in career interests resulting from the interaction between a...
