Nanostructured Diatom Biosilica Stationary Phase for Thin-layer Chromatography Separation of Polar, Ionic Analytes

Creator:: Kraai, Joseph A.
Abstract:: Despite an expansive selection of available thin-layer chromatography (TLC) stationary phases, almost none are well-suited for separation of polar, ionic analytes. This work demonstrated that a highly porous stationary phase layer comprised solely of nanostructured biosilica frustules, isolated from living Pinnularia sp. diatom microalgae, improved TLC separation of the polar,...

Effects of High-docosahexaenoic Acid Microalgae and Choline in the Hen Diet on Egg Production and Lipid Metabolism

Creator:: Yonke, Joseph A.
Abstract:: The objectives of the current study were to 1) investigate the effect a high-docosahexaenoic acid (C22:6 n-3, DHA) microalgae product (MAL), and choline dosage in diets containing MAL, on egg production performance, physical egg quality, and nutritional parameters, and 2) determine whether choline dosage influences hepatic lipid metabolism of...

Spatiotemporal Phytohormone Distributions in Developing Pinot Noir Berries and the Effects of Two Viticulture Practices Thereon

Creator:: Schmidt, Joseph A.
Abstract:: In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...

Equal contrast tint progressions for computer cartography

Creator:: Bernert, Joseph A.
Abstract:: A psychophysical bisectioning experiment was performed to evaluate equal steps within tint progressions on a high resolution graphics terminal. In the bisectioning experiment each respondent partitioned a tint progression by interactively defining colors that were perceptually equidistant between two previously defined colors. Twenty test subjects performed the test on the...

Development of a land evaluation and site assessment (LESA) model for forestry in Lane County, Oregon

Creator:: Pepi, Joseph A.
Abstract:: A Land Evaluation and Site Assessment (LESA) Model was developed for the forested soils of Lane County, in western Oregon, based on soil potential ratings and indexes of parcel size and adjacent and surrounding land use conflict. Lane County's economy is heavily dependent on resource production uses of land for...

Precipitation estimation in mountainous terrain using multivariate geostatistics

Creator:: Hevesi, Joseph A.
Abstract:: Estimates of average annual precipitation (AAP) are-needed for hydrologic modeling at Yucca Mtn., Nevada, site of a proposed, high-level nuclear waste repository. Historical precipitation data and station elevation were obtained for stations in southern Nevada and southeastern California. Elevations for 1,531 additional locations were obtained from topographic maps. The sample...

Object oriented simulation tools for discrete-continuous, stochastic-deterministic simulation models

Creator:: Fisher, Joseph A.
Abstract:: In this thesis an introduction to simulation and object oriented programming discusses the need for the creation of several classes which directly support object oriented simulation. The author places no restrictions on the type of simulations that can be conducted and simulation practitioners will find that the classes provided lay...

How well do professional developers test with code coverage visualizations? : an empirical study

Creator:: Lawrance, Joseph A.
Abstract:: Professional software developers do not test code adequately, even though testing tools are widely available. Until developers realize the deficiencies in their tests, inadequate testing of software seems likely to remain a major problem. To support developers writing tests, industry and researchers have proposed systems that visualize “testedness” for end-user...
