Evidence for the Potential Hybridization of Ammophila breviligulata and Ammophila arenaria in the Pacific Northwest.

Creator:: Borland, Joshua J.
Abstract:: Coastal dunes are dynamic and unique ecosystems. On the Pacific coast, dunes are generally dominated by the beach grasses, Ammophila breviligulata and Ammophila arenaria, two invasive species introduced in the early 1900’s to stabilize sand and create foredunes that serve to protect people who live behind them. Recently, a novel...

Studying the ancient parasitic cnidarian, Sphaerospora elegans, leads to better understanding of oligochaete diversity and myxozoan discovery

Creator:: Lehrburger, David J.
Abstract:: Myxozoans are microscopic parasites, related to corals and jellyfish. Most Myxozoa probably have two-host lifecycles that require a vertebrate (typically fish) and invertebrate (annelid or bryozoan). However no life cycle is known from the Sphaerospora lineage. I hypothesized that the life cycle of Sphaerospora elegans, a myxozoan parasite of three-spined...

Nutrient limitation of dune grasses in a U.S. Pacific Northwest coastal dune system

Creator:: Barker, McKenzie J.
Abstract:: Coastal dunes provide many functions and services including coastal protection, recreation, and habitat. Vegetation contributes to dune growth and stability, thereby increasing the coastal protection value of dunes. On the U.S. Pacific Northwest coast, the dominant dune grasses are the introduced non-native American beachgrass (Ammophila breviligulata) and the native American...

Engineering a Profiling System for a Robotic Oceanographic Surface Sampler

Creator:: Shannon, Robert J.
Abstract:: ROSS (Robotic Oceanographic Surface Sampler) is an autonomous boat, equipped with oceanographic sensors, used for studying the ocean’s surface. One of its advantages over traditional research vessels is its ability to sample near glaciers, an area too dangerous for manned ships. In order to properly ascertain deep ocean heat’s effect...

PCR-based Sequencing System across Chlamydia trachomatis

Creator:: Roetcisoender, Jake
Abstract:: Chlamydia trachomatis is an obligate intracellular pathogen that affects millions of people worldwide via ocular or reproductive tract infection. Despite obvious differences in site of infection, there has been shown to be high levels of sequence conservation across C. trachomatis. This high level of sequence conservation is hindered with a...

Advanced Solvent Purification Process Design using Aspen HYSYS and Feasibility Studies

Creator:: Meeuwsen, Rachel M.
Abstract:: High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...

Effect of Substrate to Inoculum Ratio on Outcomes of In Vitro Rumen Fermentation Studies

Creator:: Remy, Jon D.
Abstract:: The objective of this study was to identify the varying effects of altering the rumen fluid: substrate ratio on the outcomes of in vitro rumen fermentation. In vitro fermentation is a useful tool for evaluating the energy value of feedstuffs and the effect of feed additives on Volatile Fatty Acid...

Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

Creator:: Trobough, Nathaniel D.
Abstract:: This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

Preliminary deployment and evaluation of geophone sensors for monitoring wave activity: GeoMoteShield

Creator:: Lathrop, Eve
Abstract:: This study focuses specifically on the investigation of a new, inexpensive geophone system and its application to monitor wave activity. Studies of seismic observations of coastal cliffs suggest that ground motions generated from local ocean waves may provide a surrogate to limited wave buoy data to quantify the wave contact...

Exploring maize pollen with microscopy: confocal, fluorescence and time-lapse imaging

Creator:: Hartman, Rogue D. J.
Abstract:: Pollen, the male product of the flower, is a crucial component in plant reproduction, as it transmits the sperm cells to the female structures, enabling fertilization and subsequent seed production. A major transition of the pollen life cycle, triggered upon pollination of female floral tissue, is from a dormant pollen...
