Integrating Microfluidics and Integrated Circuits toward a CMOS-Based Cell Counter

Creator:: Bishop, Kevin W.
Abstract:: Cell counting is a key tool used in biological and clinical laboratories, but at present, commercial cell counters are large and expensive. CMOS technology is a promising platform for creating small, low-cost sensors but currently lacks a robust method of directly interfacing these sensors with the microfluidic networks needed for...

Soil Property Effects on Willamette Daisy (Erigeron decumbens) within William L. Finley National Wildlife Refuge

Creator:: Day, Emily S.
Abstract:: Plant species diversity plays an important role in maintaining ecosystem function and the services that ecosystems provide. Diversity is threatened by habitat loss, invasive species, and global climate change. Willamette Daisy (Erigeron decumbens), an endangered species, has been reintroduced at two different sites (Field 29 and 8N) within William L....

Pollen fidelity of Apis mellifera L. during pollination of Limnanthes alba Hartw. ex Benth. ssp. alba, Limnanthaceae

Creator:: Watkins, Ann J.
Abstract:: Limnanthes alba, commonly known as meadowfoam is a popular commercial crop because its seed oil is composed of long carbon chains that provide it with high oxidative stability and consequently make it a desirable ingredient in cosmetic products. As a commercial pollinator, the western honey bee, Apis mellifera, may be...

Lamb growth and pasture production in agrivoltaic production system

Creator:: Andrew, Alyssa C.
Abstract:: Grasslands and croplands located in temperate agro-ecologies are ranked to be the best places to install solar panels for maximum energy production. Therefore, agrivoltaic systems (agricultural production under solar panels) are designed to mutually benefit solar energy and agricultural production in the same location for dual-use of land. However, both...

Experimental Design Approach for Evaluation of Airfoil-Driven Energy Harvesting

Creator:: Strahl, Jordan D.
Abstract:: An experimental setup has been partially developed to investigate the impact of an actively controlled trailing edge component upon the energy harvesting performance of an oscillating airfoil in a pitching and heaving regime. While previous and current efforts have and continue to function to characterize the performance of such a...

Isolating Non-Blackbody Radiation Spectra from Low-Bandgap LEDs near Zero Bias

Creator:: Teo, YiPeng
Abstract:: The study of carrier transport in light-emitting diode (LED) has been researched extensively in the past. However, most studies were implementing voltages above the turn-on voltage of the LED. Research on LEDs well below the turn-on voltage threshold is comparatively scarce for good reasons. When the supply voltage is below...

The Management Control System in a Growing Family Firm

Creator:: Henderson, Kali L.
Abstract:: Many firms start off as small family businesses which are controlled through the culture imprinted on employees by the founder. As the business grows, family owners and the executives that they hire, face a dilemma – how do they manage the trade-off between wanting to control the business in order...

A taxonomy of biomolecular features

Creator:: North, Jacob L.
Abstract:: The scientific method applies hypothesis testing to material samples through experimentation, measurement, and data analysis, which produce representations—or features—that describe phenomena of interest. Biomolecular features come in numerous forms such as values, matrices, graphs, three-dimensional structures, trajectories, and molecular surfaces. Researchers have tested thousands of features related to protein molecules...

Modeling of Power Efficiency in a Magnetohydrodynamic Generator

Creator:: Redle, Michael T.
Abstract:: The introduction of an Magnetohydrodynamic (MHD) generator in coal or natural gas energy plants could significantly increase the efficiency by converting kinetic and thermal energy of the combustion exhaust to electrical energy by the generation of a Faraday and Hall current. The traditional MHD system was transformed into a simplified...

Effects of thermal stressing on the turbulent flame speed of jet fuel

Creator:: Alkhalifa, Ammar M.
Abstract:: Gas turbine engines for propulsion applications can use fuel as a coolant, exposing the fuel to high temperatures well within the ranges associated with thermal decomposition. Species produced as a result of these processes have been shown to correlate with changes in the combustion performance of the fuels. In this...

Environmental Transformations of Nanoparticles in Natural Water Systems using a Hydrophobic and Hydrophilic Dye Assay

Creator:: Turnquist, Macklin C.
Abstract:: Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...

Comparison of three diagnostic assays in the detection of Pseudoloma neurophilia in zebrafish

Creator:: Kreul, Taylor G.
Abstract:: As the zebrafish (Danio rerio) becomes increasingly popular as a biomedical model for various laboratory studies, the need for efficient and accurate diagnostic assays for the pathogens that infect it has grown. The most common pathogen infecting laboratory zebrafish is Pseudoloma neurophilia, a microsporidium that has been known to cause...

Using 16S rRNA Gene Amplicon Sequencing and quantitative PCR (qPCR) to Evaluate Microbial Community and Pathogen Dynamics in Acropora cervicornis Corals

Creator:: Patel, Shalvi H.
Abstract:: Coral reefs are diverse ecosystems and serve many purposes including preventing erosion on coastlines and acting as a source of food, income, and culture. Acropora cervicornis, a staghorn coral, has faced a significant 80-89% decline in the Caribbean, attributed to a poorly-characterized epizootic, White Band Disease (WBD). Previous studies showed...
