Are they what they eat? A stable GIT microbiome characterized in P. resecata

Creator:: Gustafson, Tarah N.
Abstract:: Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...

Dielectric Properties of Perovskite Ceramics Based on BaTiO3 and Bi(Mg1/2Ti1/2)O3

Creator:: Sundahl, Christopher S.
Abstract:: The properties of (1-x)BaTiO3-xBi(Mg1/2Ti1/2)O3 (BT-BMT) ceramics were fabricated from reagent-grade ceramic powders by solid-state methods and investigated for solubility, relative permittivity, dielectric loss, polarization, and electromechanical strain. The solubility limit was found to be between x = 0.3 and 0.4. Ba-deficient samples were fabricated, corresponding to stable single-phase compositions; these...

Investigation of MoS2 with Ambient Pressure X-ray Photoelectron Spectroscopy

Creator:: Dardzinski, Derek P.
Abstract:: Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...

Thermoelectric Characterization of SiliconWafers and Cu₁₂Sb₄S₁₃ Variant Thin Films

Creator:: Snyder, Rodney Austin
Abstract:: The Van der Pauw method for transport measurements of conductivity and carrier concentration were tested on indium-tin-oxide (ITO) films and silicon wafers, and then implemented on Cu10xAgxZn2Sb4S13 thin films. ITO was used as a test case for high temperature transport measurements because it a well characterized semi-metal. The mobility of...

Anaerobic Dehalogenation of Trichloroethene by Encapsulated Dehalococcoides mccartyi

Creator:: Lukens, Eileen P.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) like trichloroethene (TCE) were mostly used to replace drying cleaning fluids which contained hydrocarbons like benzene, and were highly flammable. Through improper disposal, storage, and spills, TCE and its downstream products, like cis-dichloroethene (cDCE) and vinyl chloride (VC), leached into groundwater and threaten human and environmental...

Hacking RFID Tags to Produce Economical Soil Moisture Sensors

Creator:: Stoddard, Brett S.
Abstract:: Currently available soil moisture sensors have intrinsic limitations that limit their adoption by industry. Depending on the technology, these limitations may include high costs, battery requirements, precice manual installation, high cost, and/or constrictive legislation that regulates their use. A passive soil moisture sensing system based around RFID technology would allay...

Using Community Voice to Build Trust in State Systems

Creator:: Yasui, Kendra M.
Abstract:: The COVID-19 pandemic has highlighted the importance of community trust in state systems. Consideration of community concerns by public health agencies may help to establish more equitable policies, engaging community in emergency response and promoting inclusivity and trust. This paper outlines varying definitions of trust, then describes key considerations in...

Environmental Transformations in Hydrophobicity of TiO2 P-25 Nanoparticles in Alsea River Waters

Creator:: Boenisch, Kylie
Abstract:: Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...

A Java implementation of the elliptic curve digital signature algorithm using NIST curves over GF(p)

Creator:: Stadick, Rhea
Abstract:: The Elliptic Curve Digital Signature Algorithm (ECDSA) is a public key cryptosystem used for creation and verification of digital signatures in electronic documents. In this thesis, we created a Java applet that provides the functionality of the ECDSA using all of the NIST elliptic curves over GF(p). This applet was...

The Creation of a Bilingual Children’s Book to Promote Mental Health Services among U.S. Latin@s

Creator:: Tolmach, Oresta S.
Abstract:: Although U.S. Latin@s are more affected by major depressive disorder than non-Latin@ whites, they are less likely to utilize mental health services. The purpose of this project is to create a children’s book that promotes the utilization of mental health services among U.S. Latin@s with major depressive disorder. This book...
