Step-Rate Manipulation For Improved Running Economy At A Performance, Noah Clemens

Honors Theses

The relationship between step rate (SR) and oxygen consumption (VO2) is non-linear, with an individual’s optimal SR minimizing VO2. Prior studies suggest highly trained runners do not self-select this optimal SR, though most research has focused on submaximal speeds. This study assessed whether highly trained male distance runners self-optimize SR at a performance pace. Twelve participants (22.5 ± 3.7 years) completed nine 4-minute treadmill trials at 4.96 m/s. The first trial was self-paced; remaining trials were metronome-cued (170–200 steps/min). VO2 was plotted against SR and modeled with a second-order polynomial to estimate optimal SR. Four participants were excluded due to …

Investigating Macrophage Interactions With Listeria Monocytogenes Grown Under Different Conditions, Patrick J. Hurst

Honors Theses

Listeria monocytogenes is a Gram-positive, intracellular pathogen responsible for the deadly foodborne illness listeriosis. It is known to express different virulence factors in response to different environmental factors, influencing how the pathogen interacts with the host immune system. From food packaging to digestion, L. monocytogenes is exposed to many different environmental conditions. My honors thesis research focused on two conditions—cold storage and the presence of antimicrobial food additives—and how these conditions affect immune responses against L. monocytogenes. One of the first immune defenses that L. monocytogenes encounters in the body is the phagocytic macrophage. Macrophages can exhibit different shapes or …

Design And Optimization Of Lattice-Integrated Plif Cages Using Additive Manufacturing And Finite Element Modeling, Olivia Draughn

Honors Theses

The customization, characterization, and development of biomedical implants through additive manufacturing (AM) and finite element methods (FEM) becomes imperative to the success of surgical operations and long-term patient satisfaction. To combat stiffness mismatches and prevent stress shielding between implant and bone tissue, lattice structures can be implemented within bone implant design to reduce the effective Young’s modulus (EYM) of the implant and to promote osteointegration within bone tissue. Lattice structures are highly customizable, three dimensionally repeated patterned unit cells that can be manipulated to mimic the porous nature of bone tissues to increase implant-bone interface longevity. The study presents the …

Optimizing A Perfusion-Compression Bioreactor Via Python Integration, Umamah Amer

Honors Theses

Bioreactors are widely used in tissue engineering to support cell and tissue growth under controlled conditions. Perfusion-compression bioreactors, like the one developed in our lab, can be used to replicate the physiological loading of bone on 3D-printed scaffolds. When seeded with osteogenic cells and subjected to mechanical loading, these scaffolds serve as a model to study osteogenesis. To simulate physiological conditions, the bioreactor must apply 1000 compression cycles at forces up to 200 N, three times daily over 14 days. Upon implementation, validation testing and experimental studies exposed several limitations in the bioreactor’s control code. The system was initially programmed …

Speed Of Shear Waves As A Function Of Frequency In Micellar Fluid, Michael Basha

Honors Theses

The purpose of this experiment was to investigate the frequency dependence of shear wave speed in a micellar fluid. A high-concentration CTAB-NaSal micellar fluid seeded with microspheres was used in the experiment. Shear waves were generated using a wave driver and a function generator, while a high-speed camera captured video recordings. Since the frequency of the wave driver producing the shear waves in the micellar fluid is a constant value set by the experimenter, changes in shear wave speed can be determined by measuring their wavelengths at different frequencies.The captured video was then broken down into frames using MATLAB. These …

Balancing Parental Rights And Child Welfare In Custody Decisions Involving Mental Health, Colette Methling

Honors Theses

This thesis examines the evolving intersection of parental rights, child welfare, and mental health within the context of termination of parental rights proceedings. Historically, mental illness was often viewed as a categorical disqualifier for parenting, with courts relying on stigmatized assumptions rather than individualized evaluations. These early judicial approaches, influenced by eugenics and social biases, as exemplified by Buck v. Bell (1927), led to systemic injustices and overly broad state interventions into family life.

Through a doctrinal and historical legal analysis, this thesis traces how U.S. courts have gradually moved from rigid, diagnosis-based determinations toward more nuanced, evidence-based standards. It …

The Effect Of Lithium On Intracellular Myo-Inositol Levels In Human Lymphoblasts Of Bipolar Disorder Patients, Ntakirutimana Francine

Honors Theses

Bipolar disorder is a chronic disorder characterized by mood swings of mania and depression. Bipolar I is characterized by intense mania, while bipolar II is characterized by hypomania and depression. Currently, there is no cure for bipolar disorder; however, one mainstay of treatment is lithium, which is hypothesized to alleviate symptoms by reducing myo-inositol.

In this study, the effect of lithium on intracellular myo-inositol was determined in lymphoblasts derived from bipolar disorder patients and compared to that of lymphoblasts from a neurotypical individual. At 1mM lithium, the data showed increased myo-inositol levels across cell lines; however, the results were not …

Honors Theses

Homeostasis is essential for the health and development of all organisms, serving as a universal defense mechanism that ensures the stability of physiological processes faced with external and internal stimuli in the form of health challenges (Archana et al., 2017). Maintaining homeostasis is crucial for our health, as it helps keep the body's internal balance. However, this delicate equilibrium is challenged by various environmental factors, such as diet, exposure to chemicals, and fluctuations in temperature (Collier et al., 2017). These disruptions can lead to dysfunction in cellular processes, particularly affecting the production and regulation of proteins vital for biological functions. …

The Effect Of Female Athlete Menstrual Cycles On Their Athletic Performance, Millie Allgood

Honors Theses

Previous research studying the effects of the menstrual cycle on athletic performance has focused on women who do not participate in any athletic activity or participate at a recreational or professional level (Dupuit et al., 2023; Ekenros et al., 2022). Few studies have tested collegiate athletes and those which have examined theoretical effects or psychological impacts rather than direct performance outcomes (Carmichael et al., 2021). It is widely agreed upon that reproductive hormones have broad influences throughout the body including body composition, response to stress, appetite, energy expenditure, and blood-glucose regulation. These factors directly contribute to physiological abilities such as …

Antioxidant Activity Of Pamam Dendrimer Stabilized Ascorbic Acid, Gabriella Srikureja

Honors Theses

Ascorbic acid (vitamin C) is an essential micronutrient for human health. It acts as an enzymatic cofactor in anabolic biochemical pathways such as the synthesis of collagen, dopamine, and norepinephrine. Unfortunately, this versatility comes at the cost of a high degradation rate both in and outside of the food matrix. Previous research exploring stabilizing aqueous ascorbic acid through Poly(amidoamine) (PAMAM) dendrimers found success in reducing the rate of degradation.

To confirm the antioxidant activity of ascorbic acid in its stabilized dendrimer complex, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assays examined via Cary 5000 UV-Vis-NIR spectrophotometer found that performing the DPPH assay under aqueous conditions …

Assessing A Possible Effect Of Males' Pheromones In The Phonotaxis Of Female Acheta Domesticus, Addy Rodriguez Velasco

Honors Theses

Acoustic communication in crickets is crucial for reproduction. Females respond phonotactically to the male's call. Prior research evaluating the selectivity of phonotaxis in these females, has focused on females that have been isolated from males from day 1 after metamorphosis. However, assessing phonotaxis in females raised in the presence of males, remains to be done. This study aims to investigate the phonotactic response of female Acheta domesticus that were housed with males prior to testing.

Results indicate that on average, male-exposed females respond phonotactically to a wider range of calls that those females in the control group. These results rule …

It also examines predisposing factors, diagnostic tools, and interventions used to manage these conditions. Furthermore, the review considers how intersecting social factors- such as race, low socioeconomic status, education, culture, and barriers to healthcare- contribute to disparities in …

The Prillwitz Mammoth: Taxonomy, Sex, Age, & Delayed Skeletal Maturation Of A Geologically Young Mammoth, Anna Rybachek

Honors Theses

The Prillwitz mammoth, a nearly complete mammoth skeleton found in Southwest Michigan in 1962, is one of the geologically youngest mammoths from North America (AMS C-14 date: 11,300 ± 100 BP). Bones are well preserved; some long bones show post-mortem flaking, scratches, or grooves of unknown origin. All long-bone epiphyses remain unfused except the distal humerus, suggesting it was < 28 years old at death. In contrast, the skull and mandible preserve M3s and m3s, respectively, that are in mid-wear, indicating an Asian Elephant Year dental age of ~45-50 years. Long bone size and inferred shoulder height are consistent with the size of a large woolly mammoth (Mammuthus primigenius) or small to mid-sized Columbian mammoth (Mammuthus columbi), but dental evidence is most consistent with M. columbi.

Pelvic dimensions suggest it is a male. The ≥ 17-year mismatch between age inferred from tooth progression and wear (~45 Asian Elephant Years) and age inferred from epiphyseal fusion (< ~28 Asian EY if male) may indicate either substantially accelerated dental progression or delayed skeletal maturation for this mammoth; we deem the latter more likely. Based on modern analogs, delayed maturation could have been due to severe malnutrition, hormonal imbalance, illness, or genetic factors. Given the geologically young age of the Prillwitz mammoth (likely near the time of mammoth extinction), we speculate that delayed skeletal maturation may have been attributed to environmental stressors near the end of the Pleistocene. Further work is warranted on very late mammoths.

Distracted But Still Listening: How Cognitive And Perceptual Load Affect Multisensory Integration, Eddie Lee

Honors Theses

There is an ongoing debate about whether multisensory integration (MSI) occurs automatically and before attention is allocated or if multisensory integration occurs after attention is allocated and is subject to top-down attentional control. A recent study investigated this by manipulating the availability of attentional resources in a dual-task paradigm, finding that when the demands of the secondary task increased, susceptibility to the Sound-Induced-Flash-Illusion, a non-speech audiovisual illusion, also increased (Michail & Keil, 2018). This was taken as evidence for the role of post-attentive, top-down control during MSI. In the present study, we extend this logic to explore the role of …
