Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:: Bell, Nicole C. S.
Abstract:: Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Radioactive Isotope Matching for an Embedded System

Creator:: Wagner, Samuel T.
Abstract:: The goal of this project is to create a lightweight radioactive isotope identification program for an embedded system using the C programming language to perform isotope matching on a subset of isotopes. First, the physics behind radioactive spectra and their key features are explained. Next, the characteristics of the spectra...

The Effect of HSA and Hematocrit on the Cake Collapse Temperature of Lyophilized Red Blood Cells

Creator:: Runyon, Daniel E.
Abstract:: Freeze-drying, or lyophilization, has shown great promise in addressing many of the logistical challenges of storing and preserving red blood cells (RBCs). A crucial part of any future RBC lyophilization protocol is the primary drying temperature, which affects the sample drying rate and the dried cake’s ability to form a...

Testing a Theoretical Model that Predicts Extinction of Populations Forced by Random, Episodic Disturbances

Creator:: Olsen, Conner J.
Abstract:: We do not fully understand reasons behind extinction of populations and species. Consequently, our ability to anticipate extinction (which can be considered a permanent type of an ecological threshold) has remained elusive. In particular, it is not clear how the attributes of episodic disturbance regimes can elicit extinction. In this...

The Mathematics of Critical Shifts in Ecological Networks with Alternative Stable State Theory, A Potential Framework for Early Warning Indicators

Creator:: Kupperman, Michael D.
Abstract:: A long running problem in mathematical biology is the prediction of extinction events, a specialized case of the larger global stability problem found in differential equations and dynamical systems theory. A central technical question is how to introduce the randomness observed in real ecological systems not accounted for in deterministic...

“A Fool For His Client:” Religion, Law, and Insanity in Nineteenth-Century America

Creator:: Reck, Logan A.
Abstract:: When Charles Guiteau killed U.S. President James Garfield, he claimed that God had ordered him to do so. During his trial, Guiteau’s lawyers plead not guilty by reason of insanity, and the question of Guiteau’s innocence or guilt quickly became a question about the very nature of insanity itself. In...

Comparing the autoignition performance of chemical kinetic models for toluene using data extracted from the literature

Creator:: Mayer, Morgan
Abstract:: Real transportation fuels contain a wide range of hydrocarbon species, and this complexity poses challenges for modeling. Surrogates with a simpler blend of hydrocarbon reference fuels can approximate the physical and chemical characteristics of real fuels and enable practical simulation of the reacting flows that occur in engines and combustors....

Evaluating the Toxicity of Organophosphate Flame Retardants in Zebrafish

Creator:: Britsch, Kimberly A.
Abstract:: Flame retardants are in many home products including couches, chairs, and electronics. The most commonly used flame retardants contained polybrominated diphenyl ethers (PBDEs) until 2004, when the majority of these chemicals were phased out. PBDEs were found to be persistent, bioaccumulative, and toxic to both humans and the environment. Organophosphate...

Old Crops in a New World: Bringing Andean Tuber Crops to the Pacific Northwest

Creator:: Reers, Michelle
Abstract:: Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua...

Analysis of Mercury Content in Dried Urine of Individuals with Amalgam Fillings Through theUtilization of Direct Mercury Analysis

Creator:: Kapur, Suchit
Abstract:: Mercury exposure is widely common throughout the world, ranging from sources such as dental amalgams, fish and seafood consumption, industrial mining, and medicine. A straightforward, efficient, and affordable protocol to measure urine mercury content would greatly contribute to assessing one’s mercury exposure and in categorizing populations that are more vulnerable...
