Materials Science and Engineering Faculty Research & Creative Works

Zirconium diboride was irradiated with 5 MeV Au^2 + , 7 MeV Au⁴⁺ and 10 MeV Au³⁺ ions at room temperature and 570 °C to doses from 1 to 8 displacements per atom (dpa). Grazing incidence X-ray diffraction (GIXRD) analysis revealed no secondary phase formation. Rietveld analysis of the GIXRD data indicated an accumulation of microstrain at low dpa and room temperature. Dislocations observed in transmission electron microscopy (TEM) cross-sections are likely the main contributor to the microstrain. High dpa and high-temperature samples exhibit lower lattice distortion than lower dpa samples, suggesting the presence of enhanced defect …

Materials Science and Engineering Faculty Research & Creative Works

Using first-principles calculations and companion experimental validations, we demonstrate that the valence electron concentration (VEC) can be used to self-consistently parameterize the bonding characteristics of high-entropy diborides (HEBs) and in turn predict their mechanical properties. When VEC is 10.0 per formula unit (f.u.), HEBs enter the superhard category where Hv>40GPa because bonding states are optimally filled to resist shear deformation. Conversely, above or below a VEC of 10.0, the hardness decreases due to the filling of antibonding or the emptying of bonding states of the HEBs, respectively. This result is supported by analyses of the electronic structure, bonding, antibonding, …

Evaluating The Feasibility Of Recycled Asphalt Pavement And Warm Mix Asphalt In California Highway Construction, Ryan A. Milanesa

Construction Management

California’s highway infrastructure faces increasing material costs, limited aggregate availability, and aggressive greenhouse gas reduction mandates. Reclaimed Asphalt Pavement (RAP) offers a practical solution to reduce virgin binder demand and improve sustainability. However, Caltrans maintains conservative RAP limits due to concerns regarding stiffness related cracking and long term durability. This research evaluates the feasibility of increasing RAP content to approximately 40% when combined with Warm Mix Asphalt (WMA) technologies under California performance standards. A performance based framework was developed by reviewing federal guidance, peer-reviewed fatigue studies, life cycle cost analysis, and environmental assessment literature. Findings indicate that high RAP mixtures …

Improving Equity Within The Holistic Admission Process Through Race-Neutral Holistic Review: A Before And After Cross-Sectional Study, Megan Eikenberry, Kylie Scott, Jaime González, Josh Subialka, Lacey Frankland, Patrice Ayala, Mark Kargela, Byron Russell

Physical Therapy Faculty Publications

Introduction: The US Physical therapist (PT) workforce lacks racial and ethnic diversity, which may contribute to health disparities. Holistic review (HR) admission methods may improve workforce diversity by evaluating applicants' academic metrics, experiences, and personal attributes. Holistic review processes must adapt following the 2023 Supreme Court ruling prohibiting race-based admission criteria.

Review of literature: Holistic review criteria are program-specific and align with institutional and programmatic goals. While HR is shown to improve student body diversity, most PT education programs heavily emphasize academic metrics, which may disadvantage racial and ethnic minority (REM) applicants from acceptance. This study examines the racial and …

Artificial intelligence tools are entering K–12 literacy classrooms at an unprecedented rate, yet most have not undergone independent validation. This brief examines how educators can evaluate AI tools through the lens of cognitive science and instructional design. Drawing on the Expanded Instructional Hierarchy (Odegard & Gierka, 2025), we present a framework that links learning phases to the memory systems and cognitive processes that underlie literacy development.

2025 Late-Season Bell Pepper Production In High Tunnels, Lewis Jett

Midwest Vegetable Trial Reports

Bell peppers (Capsicum annuum) are widely grown as an open-field vegetable crop in West Virginia.  There is limited production of bell peppers in high tunnels.  However, the high tunnel protected microenvironment may accelerate maturity and improve quality of colored bell peppers for late-season bell peppers.  Late season peppers have high market value since open-field production has completed by the first frost in mid-October.  The objective of this research was to evaluate 7 bell pepper cultivars planted within a high tunnel in early August for late fall harvest in West Virginia in 2025.   The bell peppers were once-over harvested …

How Teachers Can Apply Learning Theories To The Five Pillars Of The Science Of Reading, Jennifer Renn

Science of Reading

This brief provides an introduction to six learning theories and guidance on how they can be used to teach the pillars of the science of reading (SOR). Because SOR is rooted in a broad range of interdisciplinary research and covers several key competencies, classroom teachers may be overwhelmed and uncertain of how to best meet students’ needs. There is also a tendency to use instructional strategies and techniques that include student repetition and recognition of information. While these approaches can help students learn to read and write, teachers should consider using a range of learning theories to better align instruction …

Here, we conduct a dual-molecular investigation into frozen squid and imitation crab products sold at American, Asian, and Hispanic grocery stores in Los Angeles, California, to assess label integrity under current U.S. Food & Drug Administration (FDA) guidance. Forty-eight squid samples from 13 retailers underwent DNA barcoding and yielded high percentage matches to 10 species across six genera. Despite broad labeling as ‘squid’, all samples matched FDA Acceptable Market Names with a 0 % mislabeling …

Situation Mouse All Floxed Up: Exploring Phenotypic Abnormalities In Bdnf Floxed Mice, Marissa A. Burkman

All NMU Master's Theses

Animal research is a contentious topic in both the scientific and general communities.  It is essential that our animal models accurately and predictably depict intended phenotypes, necessitating careful colony monitoring and maintenance.  Volunteer animal staff in the Ottem Laboratory became concerned when mice with LoxP sites flanking the BDNF gene depicted anxiety-like behaviors such as aggression, difficulty handling, and increased agitation.  Though many studies have noted behavioral and phenotypic abnormalities related to large gene inserts, few have noted abnormalities with small gene inserts such as the 34 bp LoxP site.  Brandt (2018) performed a three-stage behavioral protocol on these mice …

Time-Dependent Amplification Of Growth Rates In A Plankton-Oxygen Model, Rapha Coutin

Master's Theses

Near-bottom hypoxia occurs when dissolved oxygen levels drop to a level that is harmful to marine biology, creating biological dead zones along the ocean floor. Recent years have seen a dramatic increase in the percentage of coastal, near-bottom, hypoxic water, with the average in 2021 nearly double that of the average from 2009 to 2018 and about twenty-eight times the average from 1950 to 1980. Recent literature has linked this increase in oceanic hypoxia to the increase in upwelling-favorable winds caused by climate change. Upwelling brings low-oxygen, nutrient-rich water up to the surface, leading to plankton blooms and mass consumption …

Toxic Immortality: Rethinking Decline And Plastics With Lucretius, Jessica Croteau

Environmental Studies Faculty Scholarship

Much of contemporary environmental thought operates within paradigms of conservation, sustainability, and resilience—frameworks that assume the goal of ecological politics must be to prevent loss, preserve stability, and mitigate decline. However, these frameworks inadequately address cases where persistence and abundance, rather than disappearance, are the source of harm. By contrast, this article argues that an ecological ethic oriented toward decline, unbecoming, and decomposition reveals an alternative set of political and material stakes: not the conservation of things but their proper dissolution. Drawing from the materialist philosophy of Lucretius, the article critiques the prevailing assumption that endurance is inherently beneficial, highlighting …

La Bayadère: An Examination Of The Romantic Era In The Modern-Day, Charlene O. Font, Autumn Eckman

The Kennesaw Journal of Undergraduate Research

The Romantic Era of art saw a shift from male to female dancers on stage. The female dancer became associated with mysticism and fantasy for the benefit of the male audience. With the onset of mysticism, came the idealization of death which was a common theme in many Romantic Ballets. The ballet, La Bayadère, is a Romantic Era ballet that has been adapted multiple times within the past half-century. However in an effort to preserve its relevance to the modern-day audience, three ballerinas - Marianela Nuñez, Natalia Osipova, and Tamara Rojo - have altered the original choreography to present the …

Model For Analyzing Floorplate Morphology That Optimizes Daylighting And Cost, Andrew G. Welch, Ermal Shpuza Phd

The Kennesaw Journal of Undergraduate Research

One key method to improve the energy efficiency of a building is to enhance daylight levels, which reduces the need for artificial lighting. Elevated daylight levels are also associated with increased productivity and well-being of building occupants. Daylight levels are inversely proportional to the building compactness, where shallow floorplates and elongated buildings are associated with higher daylight levels. However, creating buildings that have more natural light comes with a greater construction cost due to larger envelope areas as well as greater operating costs due to the energy loss through the exterior envelope area. This research identifies the basic design strategies …
