Diversity, Generalization, and Specialization in Plant-Pollinator Networks of Montane Meadows, Western Cascades, Oregon

Creator:: Helderop, Edward
Abstract:: Despite the importance of plant-pollinator interactions for ecological communities, few long-term observational studies have been conducted of plant-pollinator networks. Using four years of plant-pollinator interaction data from 18 meadows in the Willamette National Forest, Oregon, this thesis examined how meadow size, the amount of nearby meadow habitat, weather, degree days,...

Comparing Random and Nonrandom Spatial Patterns of Artifacts within Lithostratigraphic Unit 3 at Cooper’s Ferry, Idaho

Creator:: Gregory, Alex R.
Abstract:: Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...

Improving the representation of large landforms in analytical relief shading

Creator:: Marston, Brooke E.
Abstract:: Relief shading is the most common type of cartographic relief representation for print and digital maps. Manual relief shading results in informative and visually pleasing representations of terrain, but it is time consuming and expensive to produce. Current analytical relief shading can be created quickly, but the resulting maps are...

Evaluating the presence of radium-226 in soil surrounding a coal-fired power plant using the multi-agency radiation survey and site investigation manual (MARSSIM)

Creator:: Herring, Thomas A. (Thomas Andrew)
Abstract:: Coal-fired power plants constitute a significant source of energy production for the United States, and are projected to do so for decades to come. Most of the scrutiny coal-fired power plants receive is in the form of environmental concerns regarding green house gas emissions of carbon dioxide, sulfur dioxide, and...

Neutron Flux-Energy Spectral Characterization of a Deuterium-Tritium Neutron Generator at Oregon State University

Creator:: Eastman, Abigail L.
Abstract:: The neutron flux-energy spectral characterization of a Thermo Fisher MP320 deuterium-tritium neutron generator was performed for two shielding configurations, one with substantial moderator between the source and the sample and one without such moderator. The STAYSL PNNL spectral adjustment code was utilized in conjunction with MCNP modelled reference spectra and...

Quantification of dry concentration factor for Cs-134 in marine diatom Thalassiosira Weissflogii

Creator:: Krzyaniak, Nathan Anthony
Abstract:: The Fukushima Daiichi nuclear disaster of 2011 made it apparent that releases of fission products to marine environments is a very real possibility. Additional data on the movement of material through marine environments can be used by radioecology personnel to assist with both ecosystem protection as well as environmental cleanup...

Locating and Quantifying Contamination Deposited in Radiation Puncture Wounds

Creator:: Wehmann, Nicholas K.
Abstract:: Internal dosimetry models show a representation of how radionuclides move through the body. This study takes a look at radiation wounds by modelling a puncture wound to the hand using Microshield software. An analysis of these models provides a triangulation method that could be used to investigate wound characteristics, as...

A Historical and Archaeological Evaluation of Fort Yamhill's Hospital Site (35PO75)

Creator:: Wesseler, Kimberly A.
Abstract:: During the summer of 2016, Oregon State University conducted preliminary excavations of the hospital at Fort Yamhill, Oregon (35PO75). Fort Yamhill (1856-1866), has long been a focus of OSU’s field schools, offering glimpses into garrison life through the eyes of the officers and the enlisted men. However, up until recently,...

Dosimetric Evaluation of Nasal Cavity Basal Cell Layer during Radiotracer Administration

Creator:: Flora, Rigel
Abstract:: New delivery methods for radiotracers are constantly being proposed. Two key properties of the delivery method must be analyzed: dose to patient and effectiveness of delivery. In this work, the localized skin dose for intranasal administration of 18F was determined utilizing MCNP code. An anatomically accurate nasal cavity was constructed...

Computational Fluid Dynamics Benchmark Analysis of an Historical Sodium Loop Experiment

Creator:: Moore, Thomas M.
Abstract:: Sodium cooled nuclear reactors are being considered for the next generation of nuclear power plants to provide clean electricity to the world. To prove the safety of these reactors, the fuel must be shown to safely handle large neutron fluxes that cause a spike in the thermal output of the...
