The Optimization Of A T-Cell Resonator: Towards Highly Sensitive Photoacoustic Spectroscopy For Noninvasive Blood Glucose Detection, Thasin Mohammad Zaman, Md Rejvi Kaysir, Shazzad Rassel, Dayan Ban

Electrical and Computer Engineering Faculty Research

Noninvasive blood glucose monitoring is crucial for diabetes management, and photoacoustic spectroscopy (PAS) offers a promising solution by detecting glucose levels through human skin. However, weak acoustic signals in PAS systems require optimized resonator designs for enhanced detection sensitivity. Designing such resonators physically is complex, requiring the precise identification of critical parameters before practical implementation. This study focused on optimizing a T-shaped photoacoustic resonator using finite element modeling in a COMSOL Multiphysics environment. By systematically varying the geometric design parameters of the T-cell resonator, a maximum increase in the pressure amplitude of 12.76 times with a quality factor (Q-factor) of …

Taraxacum Officinale Effect On The Reduction Of Pro-Inflammatory Cytokines Il-6 And Tnf-A, Bailee Bad Heart Bull, Kat Kraemer, Kira Mccallum, Ruth Teeple

Undergraduate Research Symposium 2025

Dandelion (Taraxacum officinale) is a ubiquitous plant found in every continent except Antarctica. Despite its condemnation as a weed, it has been used for centuries in traditional European, Indian, and Chinese herbal medicine for its purported digestive and diuretic properties. Its leaves contain antioxidants and bioactive compounds like taraxasterol, which have been reported to reduce reactive oxygen species production and inhibit nitric oxide production. There have been claims that taraxasterol can reduce inflammation by reducing the production of pro-inflammatory cytokines; a cytokine is a small protein released by immune cells that helps regulate inflammation, immune responses, and cell communication. Our …

Investigating The Effects Of Palmitoylation In Ovcar3 Cells, Bethany Knopp, Emu Suzuki

Undergraduate Research Symposium 2025

Ovarian cancer is a disease characterized by the abnormal growth of cells in the ovaries often due to mutations in our DNA. Because ovarian cancer is typically diagnosed at advanced stages, the survival rate is less than 40% over a five-year period. One significant influence of this cancer is palmitoylation - a post- translational modification in which fatty acid chains are added to specific cysteine residues in proteins. This modification alters protein localization, stability, and function. When dysregulated, as seen in ovarian cancer, palmitoylation can promote irregular cell growth, mutations, and ultimately cancer. However, the role of palmitoylation in cancer …

Patient To Nurse Ratios And Their Effects On Patient Care, Katalina White

2025 Celebration of Student Scholarship - Poster Presentations

While working on a medical surgical unit at hospital A, I noticed that many nurses received upwards to 7 patients per shift. This led to many patient care activities not being able to be accomplished, unsatisfactory patient outcomes, nursing dissatisfaction, and nurse turnover rates increasing. Patient care was brought into question as the nurses on the unit felt overworked and understaffed. So the objective of this project is to introduce a 4-1 ratio of patients to nurses to improve patient safety, patient outcomes, and overall patient care. QSEN thrives for patient safety and quality improvement, so implementation of this standard …

Breaking Down Terminology Of Clojure Error Messages For Beginner Programmers, John Walbran, Jaydon Stanislowski, Tristan Kalvoda

Undergraduate Research Symposium 2025

The Clojure programming language has educational potential for beginner programmers due to its clean, simple syntax and its strong focus on functional programming, an important aspect of CSci education. However, one weakness of Clojure lies in its error messages, which are messages that programmers receive when a program goes wrong. The terminology and shorthands used to convey necessary information for understanding the error are often confusing to novices. The issue is exacerbated by the fact that the error messages are phrased in terms of the underlying programming language – Java – which beginner programmers may typically be unfamiliar with. A …

2025 Celebration of Student Scholarship - Poster Presentations

CLIMBS P2 (Climate Learning, Prediction, and Building Response Systems Project 2: Paleo-perspectives) focuses on improving our understanding of historical flooding and landslide events in Kentucky using paired Holocene paleoclimate and sedimentary records. To date, few published paleoclimate records exist (Liu et al., 2013; Nunez Otano et al., in prep.). As an initial step in meeting the aims of P2, the OPaL lab at Morehead State University is focusing on completion of an in-progress latest Pleistocene - early Holocene palynology-based paleoclimate record derived from sediments in legacy Andrews/KGS cores from Big Bone Lick in Northern Kentucky. This region is the birthplace …

Effect Of Nordic Hamstring Exercise On Knee Flexor Torque In Female Athletes: A Pilot Study, Jarrod Plank, Lucy Singleton, Manuel Probst

2025 Celebration of Student Scholarship - Poster Presentations

PREVALENCE Female athletes experience Anterior Cruciate Ligament (ACL) injuries 5-6x more often than male counterparts.

PREDISPOSITIONAL FACTORS The Q-angle refers to the pull vector exerted by the quadriceps muscle on the patella which results in greater valgus load on the knee ligaments.2,3,4,5,6 Females also possess lower levels of testosterone which yield decreased ligamentous strain tolerances.

MUSCULAR IMBALANCES Sufficient hamstring contraction during the landing phase decreases ACL strain by >70%, thereby limiting anterior tibial translation (ATT) force exerted by the quadriceps. As stated by Hewett et al., females present an absence of increased hamstring/quadricep torque ratio compared to males, resulting in …

The Effectiveness Of Turn Teams In Reducing The Incidence Of Hospital Acquired Pressure Injuries, Abigaile Blackburn

2025 Celebration of Student Scholarship - Poster Presentations

It is commonly known in healthcare that pressure injuries (PIs) result in higher morbidity and mortality rates for the adult population. PIs include a range of intact, open, and deep tissue injuries related to prolonged immobility. To reduce the incidence of PIs, it is highly recommended to turn patients, usually alternating among the left side, the back, and the right side. Additionally, it is standard across most hospitals to enforce mandatory turning schedules, which is at least every two hours. The objective of the project is to investigate the effectiveness of using turn teams in hospitals and nursing homes. The …

Just Plain(S) Native: Isolating Experiences Of Non-Plains Native Students At A Primarily Plains Nasnti, Bryne Qavvik Croyle Johnson

Undergraduate Research Symposium 2025

Higher education institutions have historically underserved the needs of Native students, even when active efforts are made to the improvement of services and support. Sense of belonging is a particularly ephemeral point of student’s engagement with a campus community, and studies about Native students don’t always account for the vast cultural differences between the different tribes and villages. My aim with this study is to present for consideration the isolating effects of culturally nonspecific services and groups on Native students at the University of Minnesota, Morris, a Native American-Serving Non-Tribal Institution (NASNTI). Employing ethnographic interview methods and discursive analysis, I …

Breaking The Cycle: Reducing Maternal Mortality Disparities In Minnesota, Grace Hambike

Undergraduate Research Symposium 2025

A comparative analysis of Minnesota's maternal mortality rates with states implementing successful maternal health initiatives and a review of policies supporting doulas, midwives, and culturally competent care models. Conclusions show that addressing maternal mortality disparities requires systemic healthcare reforms and culturally competent interventions. Expanding access to doulas, midwives, and community-based care can significantly improve maternal outcomes. Future research should focus on long-term effects of policy changes and continued surveillance of maternal health disparities.

Investigating The Effect Of Soil Origin On Antibiotic Production In Streptomyces, Emu Suzuki

Undergraduate Research Symposium 2025

Streptomyces bacteria produce antibiotics that inhibit competing microorganisms. We hypothesized that Streptomyces from the rhizosphere (around plant roots) would be more likely to produce antibiotics than those from bulk soil (further away from roots). Soil samples were collected from rhizosphere and bulk soils in transitional and long-term organic fields of corn and alfalfa. Streptomyces from these soils were cultured on glucose-asparagine agar media. Their antibiotic production was evaluated by testing whether they could inhibit the growth of two target Streptomyces strains. No significant effects of soil type (rhizosphere vs. bulk), crop, or management on antibiotic production were observed for one …

An Introduction To The Sphecidae Of Eastern Kentucky, Dawn Barnett, Kyah Brinegar, Gracie Burdette, Sean O'Keefe

2025 Celebration of Student Scholarship - Poster Presentations

The Sphecidae are solitary wasps that can be used to assess biodiversity on a larger scale. Sphecidae are called solitary because they do not live in colonies but rather in dirt burrows, constructed nests, and existing cavities. Their behavior reflects their name as they rarely sting people and do not mind them much, as they commonly nest near or on human dwellings. Sphecidae occur worldwide and include four subfamilies: Sphecinae, Crabroninae, Nyssoninae, and Philanthinae. Of the 10,220 known species, 1200 occur in North America. Sphecidae prey on various invertebrates, including spiders, caterpillars, and bees. Members of the subfamily Sphecinae genera …
