Behavioral And Physiological Responses Of Heifers With No Prior Exposure And Those Adapted To Grazing Endophyte-Infected Tall Fescue, Tyler A. Purvis

Theses and Dissertations--Animal and Food Sciences

Data from year one of a three-year experiment was used to determine behavioral and physiological responses of heifers adapted to grazing endophyte-infected fescue (E+TF) compared to heifers naïve to grazing E+TF. In May, yearling beef heifers from KY (n=15) and MT (n=30) were stratified by body weight, hair coat score, and disposition into nine pastures and assigned to one of three treatments: KY grazing E+ (KY-E+), MT grazing E+ (MT-E+), or MT grazing endophyte-free tall fescue (E-TF) (MT-E-). Prior to grazing, two heifers per pasture were selected to be outfitted with a RumiWatch® halter (Itin+Hoch GmbH, Liestal, Switzerland) for monitoring …

This article presents the latest results of our Atacama Large Millimeter/submillimeter Array (ALMA) program to study circumstellar disk characteristics as a function of orbital and stellar properties in a sample of young binary star systems known to host at least one disk. Optical and infrared observations of the eccentric, ∼48 yr period binary DF Tau indicated the presence of only one disk around the brighter component. However, our 1.3 mm ALMA thermal continuum maps show two nearly equal-brightness components in this system. We present these observations within the context of updated stellar and orbital properties, which indicate that the inner …

Water’S Effect On The Decomposition Of Baptisia Australis, Jackson Whiteside, Adeline Beckham, Jeremy Little, Reese Cobb, Darlene Panvini

Science University Research Symposium (SURS)

Detritus, dead organic matter, is an essential part of nutrient cycling in Earth’s ecosystems. If dead organic matter could not be decomposed, dead matter would be amassed everywhere, and its nutrients could not be returned to the soil to nourish living species. Detritivores decompose this dead matter and return its nutrients to the soil. How quickly matter decomposes is influenced by a variety of abiotic factors. One abiotic factor which is of interest to decomposition is water quantity and frequency. This study aimed to test if Baptisia australis decomposes faster in dry or wet conditions. The expected results are that …

Potential Impacts Of Construction On Bat Populations In Warner Parks, Nashville, Tennessee, Jackson Whiteside, Wyatt Fooks, Jeremy Little

Science University Research Symposium (SURS)

Human development continues to alter natural landscapes, often with significant consequences for wildlife populations. Among the most sensitive taxa to such disturbances are bats, which serve vital ecological roles as insect predators, pollinators, and seed dispersers. Because bats depend on specific roosting and foraging habitats, even minor environmental changes can strongly influence their activity and diversity. A new road is proposed through an area of Warner Parks, Nashville, Tennessee which is otherwise untouched. This may affect the biodiversity and the populations of bats as a result. Wildlife Acoustic MiniBat 2 acoustic monitoring equipment was used to gather echolocation calls of …

The Relationship Between Trait Empathy And The Involuntary Mimicry Of Emotion: An Electromyographical Study Of Facial Suppression, Madison E. Dawes, Karlie Souder, Eddie Broad, Htoo Aye, Sian Huai

Science University Research Symposium (SURS)

Abstract

Facial expressions are one of the main communication styles that signify emotion and meaning across cultures and individuals. Despite it being one of our main forms of communication, in many social situations, people are required to suppress or control their emotional expressions to act in a socially acceptable manner. However, research has shown that a person’s facial muscles continue to exhibit subtle muscle and move in expressivity even when attempting to suppress emotions from others. To support this, Dimberg et al. (2002) found that electromyography (EMG) technology can detect these subtle facial movements even if they may be invisible …

Functionalizing Silver Nanoparticles With Histamine, Noah J. Deblanco

Science University Research Symposium (SURS)

Silver nanoparticles (AgNPs) are of increasing interest in biomedical research due to their antimicrobial properties, biocompatibility, and high surface-area-to-volume ratio. A major challenge, however, lies in stabilizing AgNPs under physiological conditions and understanding how their surface interactions influence potential medical applications. This project explores the synthesis of AgNPs using the Turkevich method and investigates their behavior when exposed to varying biological conditions, including changes in pH and temperature. In addition, preliminary efforts are being made to functionalize AgNPs with small biological signaling molecules to evaluate their effects on nanoparticle stability and surface interactions. Characterization is performed primarily through UV-Vis spectrophotometry, …

Theses, Dissertations and Capstones

Minority groups, including people from lower socioeconomic backgrounds, various ethnicities or races, gender non-conforming individuals, and others who are not part of the societal majority, face daily challenges due to unequal access to digital technology. From elementary school through college, the gap between students with better access to digital tools and those without becomes evident in how these technologies are used in classrooms. International students, who may be a majority group in their home country, become part of a minority in their host country as they seek better educational opportunities. These technologies, such as social networking sites, often reflect the …

Effects Of In-Stream Large Woody Debris Management On Riparian Salamander Population Dynamics, Sydney Hermann

Theses, Dissertations and Capstones

The addition of large woody debris (LWD) into streams is an increasingly common habitat restoration method used to support brook trout populations and other sensitive freshwater species. Wood jams create localized reductions of water velocity, increase organic matter retention, intensify overbank flows, and promote habitat heterogeneity. These changes enhance interaction between the floodplain and the stream which can influence forest habitat variables such as leaf litter, soil pH, moisture, and invertebrate abundance. Salamander demographics reflect the stability of these forest habitat variables, and population declines can be indicative of environmental disturbance, stress, or change. Evaluating how this trout-targeted management effects …

Implementation Of The Nurse-Driven Palliative Care Referral Protocol: A Quality Improvement Project, Khrystyna Lacombe

Doctor of Nursing Practice Scholarly Projects

Implementation of the Nurse-Driven Palliative Care Referral Protocol

Background and Purpose: Palliative care enhances quality of life, symptom management, and patient–family communication for individuals with serious illness. Despite strong evidence and national recommendations for early integration, referrals remain inconsistent and often occur late. At Advocate Sherman Hospital, only 17.9% of eligible oncology inpatients received palliative care consults. The absence of standardized referral criteria, reliance on provider discretion, and misconceptions equating palliative care with hospice contributed to delayed or missed consults. The purpose of this quality improvement (QI) project was to increase palliative care referrals by 20% within eight weeks through …

Jammed Disks Of Two Sizes In A Channel: Segregation Driven By Steric Forces, Dan Liu, Michael Karbach, Gerhard Müller

Physics Faculty Publications

Disks of two sizes are confined to a long and narrow channel. The axis and the plane of the channel are horizontal. The channel is closed off by pistons that freeze jammed microstates out of loose disk configurations, agitated randomly at calibrated intensity and subject to moderate pressure. Disk sizes and channel width are such that under jamming no disks remain loose and all disks touch one wall. The protocol permits disks to move past each other prior to jamming, which facilitates randomness in the sequence of large and small disks. We present exact results for the characterization of jammed …

Structural Impacts Of Canonical And Non-Canonical Oligonucleotide Modifications, Deepak Shrestha

Wayne State University Dissertations

Nucleic acids, including DNA (deoxyribonucleic acid) and RNA (ribonucleic acids), are the fundamental building blocks of living organisms. The events that cause modification of DNA/RNA are of interest because they impact the nucleic acid function. Targeting DNA is important for treating diseases such as cancer. Cisplatin (cisPt) is a well-studied drug that targets DNA and blocks replication, but its use is limited by adverse side effects and cellular resistance. Prevoius research addressed some of these challenges through development of platinum analogues such as carboplatin and oxaliplatin. Amino acid-linked platinum analogues (AAPt) are the focus of this thesis work. AAPt complexes …

Mass Spectrometry Combined With Chemical Biology To Study Human Ailments, Eric Thomas Jacquerio Davis

Wayne State University Dissertations

Post-translational modifications (PTMs) are essential as chemical changes that regulate protein function, activity, stability, interactions, and localization after protein synthesis. PTMs, such as phosphorylation, acetylation, and ubiquitination, can activate or deactivate proteins, influence their interactions with other molecules, and determine their cellular location. This regulation is vital for numerous biological processes, such as cell cycle control, signal transduction, and gene expression. Abnormal PTMs are linked to various diseases in humans, including parasitic infection, blood disorders, cancers, and neurodegenerative diseases, making their study crucial for understanding disease mechanisms and developing targeted therapies. In the Pflum lab, we are interested in the …

An Auto-Historia-Teoria Of Kismet Encounters: Building Bridges Between Multiple-Marginalized Identites - Queer, Latine, And Disabled - In A Colonial Education System, Rachel Torres

Wayne State University Dissertations

Existing education research has identified a series of factors that impact student identity formation, belonging, and academic performance in secondary and post-secondary education. Such research usually focuses on one to two identity groups - like ethnicity and gender or sexuality and disability. However, very few center on the experiences of queer, disabled, students of color. Using a decolonial methodological approach to qualitative research. This dissertation uses Chicana/Indigenous epistemologies as research methodologies to identify challenges students of multiple marginalized identities encounter in schooling and how they might find strength in their elders and cultural stories. The findings encourage educators to normalize …

Reducing Acute Care Visits In Oncology: A Pilot Quality Improvement Project, Judy Metropulos

Doctor of Nursing Practice Scholarly Projects

Abstract

Background: Patients receiving high-toxicity chemotherapy are at risk for post-infusion complications, which can result in unplanned hospital visits or admissions. Structured post-infusion follow-up may improve symptom management and reduce these events.

Local Problem: At North Region hospital, the 30-day post-infusion revisit rate was 31%, substantially exceeding the national average of 14.7%. A pilot program launched in 2021 reduced hospital visits by 7%; however, following its discontinuation due to staffing shortages and inadequate data collection, the rate subsequently increased, underscoring the need for sustainable interventions.

Methods: A quality improvement project was conducted in two, ten weeks phases. Phase 1 included …

The Role Of Radiation Therapy In Managing Brain Metastases, Kaylie Skovira

Medical Imaging Senior Posters

This project explores brain metastases and the critical role of radiation therapy in managing this condition. It provides an overview of general statistics, radiation therapy types, treatment options, expected outcome and prognosis. Brain metastases rank as the tenth major leading cause of death among men and women, and occur in 20-40% of patients diagnosed with cancer. Radiation therapy for brain metastases primarily involves external radiotherapy, which delivers ionizing radiation from outside of the body to targeted brain regions. Internal radiotherapy is less commonly used due to anatomical constraints.Common treatment options include: CyberKnife stereotactic radiation therapy, whole-brain radiation therapy, intensity-modulated radiotherapy, …

Magnetic Resonance Imaging Safety And Considerations, Lauren Mosier

Medical Imaging Senior Posters

Abstract

Magnetic Resonance Imaging (MRI) is considered to be a safe, non-invasive diagnostic modality. However, the presence of a strong magnetic field creates inherent risks when safety protocols are not followed. This project examines MRI safety, with particular focus on the recent fatality in New York, where a person was killed by a projectile accident in the scanner room. Such events highlight the catastrophic consequences that can result from lapses in screening procedures, inadequate staff training, or poor enforcement of zone protocols. By reviewing this incident in the context of MRI safety protocols, this project emphasizes the ongoing need for …
