Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

A comparative analysis of morphological, physiological, and biochemical adaptation to abiotic stress in intertidal porcelain crabs, genus Petrolisthes

Creator:: Stillman, Jonathon Harris
Abstract:: Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...

Mapping Wildlife-Relevant Snow Properties in Arctic-Boreal North America; Novel Modelling, Remote-Sensing, and Ground Observation Approaches

Creator:: Cosgrove, Christopher Liam
Abstract:: Arctic-boreal regions are exhibiting the symptoms of profound ecological shifts as they experience pronounced warming. Wildlife in high-latitudes are one such harbinger of change, and their populations are undergoing range-shifts, declines, and extinctions in response to their rapidly altering habitats. As the circumpolar and boreal north is snow-covered for up...

A National Five-Year Exploratory and Descriptive Analysis of Two-Year Public College Graduation Rates at Branch Compared to Non-Branch Campuses

Creator:: Harrison, Faimous J. L.
Abstract:: Branch campuses play an important part in postsecondary degree attainment by providing place-bound students from diverse socioeconomic backgrounds in different geographical regions access to education that is convenient. Their heterogeneousness structures, including enrollment size, communities, and populations served, are not accurately reflected in the majority of the research. Currently, there...

Roles of homeodomain transcription factors during organogenesis

Creator:: Xu, Jun
Abstract:: The spatial and temporal patterning of sequence specific transcription factors (SSTFs) contributes to cell type specification and organ formation during embryogenesis. Homeodomain transcription factors are evolutionally conserved among invertebrate and vertebrate animals. They are responsible for body segmentation and organogenesis. Lbx1 and Pitx2 both are homeodomain transcription factors contributing to...

Indicators of Success in Hispanic College Students

Creator:: Schulthes, Gretchen M.
Abstract:: Over the last few decades, Hispanic enrollment in postsecondary education has increased significantly. Despite increased access to higher education, there are still clear issues of educational equity when graduation and persistence rates are evaluated. While these alone are imperfect measures, they shed light on a burgeoning issue within the American...

Effects of pasture and management variables on forage intake by grazing sheep

Creator:: Lewis, Robert David
Abstract:: Grazing experiments were conducted in summer, autumn and winter to assess the effects of stock density, grazing duration, pre-grazing pasture mass and stock type on forage intake by sheep grazing at high stock densities for short durations. In summer and winter, sheep were stocked at 200 sheep/ha on 0.1 ha...

The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc

Creator:: Wall, Kellie T.
Abstract:: The imposing andesite stratovolcano is the characteristic expression of subduction zone magmatism, posing hazards to coastal populations and bearing insight into deep Earth processes. On a map of a typical volcanic arc, one can easily distinguish the approximately linear alignment and regular spacing of these major edifices that stand out...

The GED certificate as a credential for entry into and retention in the workforce : recipient and employer perceptions

Creator:: Mason, Roy B.
Abstract:: The purpose of this research was to assess the use of the General Educational Development Tests (GED) as an alternative high school credential in Oregon. A study was conducted of 469 Oregon GED recipients' and 646 private sector employers' perceptions of the GED. Both quantitative and qualitative measurements were used...
