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,...

Breeding for Fusarium resistance in Phaselous vulgaris.pdf

Creator:: Schmidt, Joseph A.
Abstract:: Fusarium solani is a chronic disease that causes root rot which affects bean production worldwide. Recently, a QTL map was generated which identified several SNPs which were found to be associated with resistance to the pathogen. To be useful in a breeding program, INDELs must be identified which co-seggregate with...

Embryonic and Larval Zebrafish Bioassays for Biomedical Research : The Larval Photomotor Response Screening Assay and Phenotype

Creator:: Fisher, Joseph A.
Abstract:: Laboratories around the world are using the zebrafish model for biomedical research and conducting investigations using morphological, physiological, behavioral, and genomic endpoints. All assays provide information, but physiological and behavioral endpoints or phenotypes are a fast way to understand how an animal is responding to its environment. We investigate the...

Methods to improve the reliability and resiliency of near/sub-threshold digital circuits

Creator:: Crop, Joseph A.
Abstract:: Energy consumption is one of the primary bottlenecks to both large and small scale modern compute platforms. Reducing the operating voltage of digital circuits to voltages where the supply voltage is near or below the threshold of the transistors has recently gained attention as a method to reduce the energy...

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...

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...

Information foraging in debugging

Creator:: Lawrance, Joseph A.
Abstract:: Programmers spend a substantial fraction of their debugging time by navigating through source code, yet little is known about how programmers navigate. With the continuing growth in size and complexity of software, this fraction of time is likely to increase, which presents challenges to those seeking both to understand and...

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...

Vegetation, Bryophytes, Lichens, Environment, and Stand Dynamics in Forests of the Swan Valley, Montana

Creator:: McCune, Bruce and Antos, Joseph A.
Abstract:: We sampled vegetation, bryophytes, lichens, environment, and stand dynamics in 56 plots in the Swan Valley, Montana in 1975-1978. The data include complete inventory of trees in 375 m2 plots, with whole-plot ocular estimates of plant cover by species, transect sampling of the ground layer bryophytes and lichens with microplots,...

Abstract:: Objectives: Parental pediatric vaccine decisions are influenced by parents' health provider networks. Complementary and alternative medical providers may be key influences in the networks of those parents who do not vaccinate their children. Methods: From March to July 2013, we conducted semi-structured interviews of Oregon complementary and alternative medical providers...

Effect of metformin exposure on growth and photosynthetic performance in the unicellular freshwater chlorophyte, Chlorella vulgaris

Creator:: Cummings, Brittany M., Needoba, Joseph A., and Peterson, Tawyna D.
Abstract:: Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers are poorly known. We exposed cultured isolates of a freshwater...

Development of an economical, autonomous pHstat system for culturing phytoplankton under steady state or dynamic conditions

Creator:: Golda, Rachel L., Golda, Mark D., Hayes, Jacqueline A., Peterson, Tawnya D., and Needoba, Joseph A.
Abstract:: Laboratory investigations of physiological processes in phytoplankton require precise control of experimental conditions. Chemostats customized to control and maintain stable pH levels (pHstats) are ideally suited for investigations of the effects of pH on phytoplankton physiology, for example in context of ocean acidification. Here we designed and constructed a simple,...
