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...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...

Evaluating desiccated cyanobacteria Aphanizomenon flos-aquae for use as a biofertilizer on Swiss Chard

Creator:: Turk, Douglas E.
Abstract:: Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta...

Beyond the Carpetbagger: The Emergence of Racialized Terms as a Political Weapon in the Reconstruction Era South

Creator:: Farrington, Caprial E.
Abstract:: The Reconstruction era, beginning in 1863, was a time of radical change and movement in American politics and society. A significant number of northern Republicans migrated southwards, for various purposes, including political involvement. To white Democratic southerners who believed they had just fought a war of northern aggression and now...

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....
