Synthetic aptamers as potential novel efflux pump inhibitors of the TolC channel in E. coli strains.
Venicia Alhawach
Antibiotic resistance is more than ever one of the most contemporary challenges threatening the health system worldwide. According to World Health Organization, previous cases of bacterial infections - once treatable with antibiotics - can now be lethal due to the uncontrolled misuse of these agents. The emergence of resistance to antibiotics and the dearth of novel drugs currently under development urge the need to search for new effective antibacterials. One of the main triggers of bacterial resistance is the over-expression of multi-drug resistant (MDR) efflux pumps. These pumps allow the bacterium to pump antibiotics out of the cell and therefore desensitizes the cells to the antibacterial inhibitory effect. In this project, we propose to design small chains of nucleic acids called aptamers to bind to and block the outer membrane channel of the efflux pump, which is a protein called TolC, as one effective way to impede antibiotic resistant bacteria from effluxing antibiotics. To generate the DNA aptamers exhibiting a binding specificity to E. coli cells, the method of a whole-cell Systemic Evolution of Ligands by Exponential Enrichement (SELEX) was applied to a random single-stranded DNA library. Whether these aptamers were able to impede the efflux activity of the E. coli pump was then evaluated using an in-vivo efflux assay.

Technical Analysis and S&P 500 Sector Returns, 2010-2016
John Tausch Gizzie
The efficient market hypothesis suggests technical analysis has no role to play in determining stock or portfolio returns. In practice, however, a large number of investment managers employ technical analysis to generate excess returns or alpha relative to the market. In this study, I test an intermediate, to long-term horizon technical analysis measure, the 200 day moving average (MA200), to determine if it generates portfolio alpha. The top ten stocks by market value in the SPDR sectors Consumer Discretionary (XLY), Information Technology (XLK), and Health Care (XLV) are treated as stock portfolios and each stock’s MA 200 is used as the portfolio weighting metric. The weighting decision rules are: (1) P>MA200 receives higher weights and (2) PS&P 500 ETF (SPY).

Teen Pregnancy: An ongoing trending the Dayton area
Sami Marie Rossiter
Teenage pregnancy can lead to a number of negative consequences related to child health and well-being. Teenage pregnancy in the Dayton area is a continuing issue from year to year. It is just one effect of social inequality that stems from people living in poverty with limited access to adequate education and opportunities. The goal of my poster is to identify the past and current trends of teenage pregnancy in Dayton, as well as give sight to what could be done in the future to improve what needs to be adjusted. There are multiple approaches that I will explore that could be used to ameliorate teenage pregnancy. To start, we must fully understand the extent of the issue and what the root causes of teenage pregnancy are.

Temperature dependent refractive index measurements for gallium nitride with implications for phase matched and quasi-phase matched optical frequency conversion devices
Jack David Kunkel
Gallium nitride is a valuable material for optical and electronic applications due to its wide band gap and high thermal conductivity. Gallium nitride has the potential for being a valuable material in frequency conversion devices such as frequency doublers and optical parametric oscillators. Optical and mechanical characterization of gallium nitride, including the dependence of the refractive index on wavelength and temperature, is important for predicting the performance of devices using this material. The method of minimum deviation was used to measure the refractive index for wavelengths ranging from 0.400 to 5.20 microns and in temperatures ranging from 20 to 225°C. Results of this characterization will be presented along with calculations relating to phase matching and quasi-phase matching in optical parametric oscillators.

The Application of Neurologically-Controlled Robotics to Actuated Feeding Arms
Timothy Edward Dombrowski
The medical industry is constantly performing research and trying to combat various diseases that afflict humans. Despite advancements in technology, there still remain diseases that have no cure but seem prime candidates for neurologically controlled robots. One such category of diseases consists of various muscular dystrophic diseases. Diseases such as ALS and Parkinson’s have limited options regarding treatment, but by brain controlled interfaces (BCI’s), robotics can help mitigate the impact on a patient’s quality of life. By utilizing a functioning mind, an electroencephalographic (EEG) helmet can be used to control various exoskeletal systems and even prosthesis in order to compensate for a damaged motor system. Through the use of neurologically controlled robotics, a user’s motor control and motor strength can be rehabilitated and maintained despite the effects of muscular dystrophic diseases. The goal of this project is to use this experiment to demonstrate the current effectiveness of brain actuated robotics and telepresence that utilize an EEG Sensor. From this assessment, recommendations and further improvements can be made to this existing technology for it to be better suited for electrical engineering and biomedical applications, while simultaneously taking the technology into a new realm of application.

The comparison of FD and RBFs collocation methods for the solution of the heat equation
Lijun Lin
The heat equation is widely used in various fields such as in industry and medicine for thermal treatment of the tumor. In this work, we are going to use two different numerical methods to solve the heat equation. It is known that Finite Difference (FD) and Radial Basis Functions (RBFs) collocation methods are both trustworthy for solving heat equation. To show the difference between the two methods, we would like to display the comparison by the final results, the error between approximate solution and exact solution, and other parameters in those methods.

The Development of a Deeper Understanding of Cantera for use in the Simulation of Modern Combustion Problems
Shane Thomas Kosir
The emergence of computing, such as multiprocessing and raw processing speed, allows for opportunities to simulate chemical models with relative ease. An open source software module, Cantera, is increasing in popularity within the combustion community as well as among other chemistry and chemical engineering disciplines. This software module can be easily integrated into Python or MATLAB and is often used to simulate problems involving thermodynamics, transport phenomena, and/or chemical kinetics. The purpose of this research is to develop a deeper understanding of physically controlling autoignition processes. The time for a fuel to autoignite, often referred to as ignition delay, is an important measure as it describes the reactivity of a fuel under given conditions. Experiments, such as rapid compression machines and shock tubes, can measure this parameter. These experimental values can be compared to simulations performed in Cantera or CHEMKIN, another chemical kinetic software similar to Cantera, to validate chemical kinetic models of given fuel species. It is of interest to investigate ignition delay as it is a contributing factor to the overall chemical timescale relating to lean blowoff (LBO) in a typical gas turbine engine. LBO represents the lowest possible fuel/air mixture, relative to the stoichiometric ratio, before a flame is not self-sustained and becomes extinguished. A better understanding of the time scales leading to LBO could allow it to be used as a criterion for the approval of alternative (non-petroleum) jet fuels.

The Effectiveness of a Personalized Peer Health Physical Education Program (PPHPEP) on the Health Related Physical Fitness, Diet, and Attitudes Toward Wellness of Students Enrolled In A University Personal-Community Health Course
Christi Michelle Begeman, Zachary John Burneka, George M DeMarco, Lenny Michael Froehlich, Megan Elizabeth Gerrity, Troy Grabowski, Megan Irene Grace, Reilly Alexzandra Madsen, Kevin Patrick McNamara, Alex George Medich, Michael Joseph Turner, Samuel Tutu, Ellison Wenzinger, Tre Alexander Whittaker
The purpose of this major course research project was to determine the effectiveness of a Personalized Peer Health Physical Education Program (PPHPEP) on the cardiovascular endurance, muscular strength/endurance, flexibility, diet, and attitudes toward wellness of students enrolled in a university personal and community health course (N=11). In the spirit of pioneering exercise physiologist and researcher T.K. Cureton, who believed that the “true laboratories in physical education [were] the pools, playfields, gymnasiums . . . ,” this study was field based and conducted primarily at the University of Dayton RecPlex. During the 2018 spring semester, students in one section of an undergraduate Personal Community Health course offered in the Department of Health and Sport Science exercised w/peers during 5 separate sessions. Team members participated in five (5) sessions conducted during class time and five (5) sessions conducted outside of class. Two of the (2) sessions included pre- and post-testing. All in exercise and testing sessions were conducted at the University’s RecPlex. Data from Pre and Post Test Fitness Testing Sessions were analyzed and compared using descriptive statistics. Qualitative data from students’ weekly Health Wellness Review Reflections (HWRR) were analyzed and compared to Insell-Roth (2016) Dimensions of Wellness Theoretical Framework to determine the effectiveness of the PPHPEP. Note: Data analysis for the PPHPEP is a Work in Progress (WIP)

The Effect of Music on Running Pace, Heart Rate and Rating of Perceived Exertion (RPE)
Alyssa Kathleen Boman, Mitchell Leonard Hester, Olivia Kathleen Lizanich, Megan Elizabeth Nemecek
The purpose of this study is to investigate how music affects different exercise variables. The variables that are being compared are running pace, heart rate, and the rate of perceived exertion. These variables will be compared when the subjects listen to music and when they do not listen to music during exercise. The goal of this study is to find out if music has a profound effect on overall athletic performance. This investigation is important for people who currently exercise often, those who are looking to lose weight as well as those who are looking to begin exercise programs for the first time. By comparing the effect of listening to music to the effect of not listening to any music on running pace, RPE and heart rate, both the benefits and setbacks of running with or without music will be presented. This, in turn, will allow us to find improvements for exercise/training and ways to improve running pace while keeping RPE low. In order to carry out this investigation, 20 students will run ½ mile while listening to "Call on Me - Ryan Riback Remix" on one day and run ½ mile without any music on a different day. Their ½ mile times, heart rate and RPE will be recorded each day following the run. The data will be collected from college students and the results will be compared. Once the data is compiled and analyzed, it will either confirm or deny the hypothesis that music will have a positive effect on running pace, heart rate and rate of perceived exertion.

The Effect of Music Tempo on Running Performance in College Students
Christian Umberto Fay, Chelsea Renee Jones, Alexandra Nicole Malsch, Megan Estelle Murray
This research aims to determine a relationship between music tempo and running performance. It has been concluded that the presence of music correlates with lower rating of perceived exertion and more positive affect than the absence of music (Hutchinson, Karageorghis, & Jones, 2014). The findings of this study would be of interest to any college student interested in learning whether his or her music choice can improve running performance. Participants will complete three, one mile runs, each with a randomly assigned condition. The conditions include listening to fast tempo music, slow tempo music, or no music. The pace of a fast-tempo song is measured at 200 beats per minute and the pace of a slow-tempo song is measured at 70 beats per minute (Edworthy & Waring, 2006). Athletic performance will be assessed by measuring mile time, rating of perceived exertion using the Borg scale, and post-workout heart rate. We hypothesize that the higher-tempo music will result in the participant to perform better on their running pace. The study is in progress and the findings will be reported at the symposium.

The Effect of Porosity on Short Beam Shear Strength of Fiberglass Composites
Kyle Alexander Lach
The presence of porosity is a well known and difficult-to-avoid defect in laminated composite materials. Excessive porosity can significantly reduce the mechanical properties of composite structures and is therefore a source of concern. In this study we investigated methods of preparing fiberglass/epoxy composite panels with the goal of being able to control the amount of porosity in the final panel, e.g. some panels with low porosity, some with high porosity. The panels were then tested for short beam shear strength, which is a property that is usually heavily influenced by interlaminar porosity. Our results indicated that, for the material system tested, the strength values were reduced only when the amount of porosity achieved a very high level. This implies that a low level of porosity can be tolerated with this material system.

The Effect of Quadriceps Strength on Abnormal Movement Patterns After ACL Reconstruction; A Systematic Review
Mark D Bugada
The current literature is replete with evidence of quadriceps femoris strength deficits after anterior cruciate ligament reconstruction (ACLR), but there is a lack of clear understanding about its relationship to movement patterns following ACLR. Elucidating the role of quadriceps strength relative to movement patterns is a vital step for improving the rehabilitation process. As a systematic review, this study aims to identify, assess, and synthesize the evidence regarding the relationship between quadriceps femoris strength and abnormal movement patterns in patients after ACLR. To achieve this, PubMEd and EBSCOhost (SPORTDiscus) databases were searched to identify studies for this review based on the following eligibility criteria: 1) available in English, 2) human subjects following an ACLR, and 3) original research examining the relationship between quadriceps femoris strength and dynamic movement patterns. From these criteria, the reviewed articles were selected, data was extracted, and results were synthesized to draw conclusions. This study found that the majority of the literature on this topic shows that quadriceps strength is related to abnormal movement patterns, with increasing strength leading to increasing in performance or decreases in asymmetry. However, the results yielded variable outcomes for lower dynamic patterns, such as walking gait, and patterns where body positioning has a greater impact on the results, like the horizontal hop and Y-Balance tests. The results of this systematic review increases understanding on the information in present literature on how quadriceps femoris strength deficits after ACLR affect movement patterns following ACLR. Understanding this relationship is vital for clinicians to develop and improve rehabilitation protocols to increase success in patient outcome.

The Effects of Adolescent Housing Condition and Voluntary Exercise on Alcohol Intake and Stress Response in Male Long-Evans Rats
Caroline A Lynch
Can regular exercise during adolescence, combined with living in a social environment, decrease both the negative effects of chronic stress and alcohol intake later in life? The aim of this research is to answer this question using a rat model that introduces a novel behavioral intervention in the form of regular voluntary exercise in order to counteract the negative effects of chronic stress caused by socially-isolated housing during adolescence. Chronic stress has been linked to the development of alcohol use disorders (AUDs) in humans, and this study attempts to both model and hamper this phenomenon in rats using voluntary exercise. Gaining an understanding of how housing conditions and exercise can play a role in subsequent alcohol intake and stress hormone levels may be useful for the advent of new pharmacotherapies for individuals with an AUD.

The Effects of Oral Rehydration Solutions (Sports Drinks) on Strength, Speed, and Endurance - A Field Study
Andrea Lynn Wisniewski
This project will study the effects of orally consumed sports drinks on physical performance on field-based tests. Dehydration happens quickly during intense exercise in hot, humid environments. Mild dehydration, noticed by a 2% drop in body weight, can cause a decrease in performance. Intense dehydration, a 10% drop in body weight, causes death. Because athletes and military personnel experience dehydration on a regular basis, having a better understanding of the best sports drinks will lead to better rehydrating programs and potentially save lives. Most sports drinks contain carbohydrates and ions to refuel the body after it burns through its endogenous stores. Gatorade, the most popular commercially available drink, is mostly table sugar, salt, and potassium. This study will into how if CeraSport can prevent dehydration better than Gatorade. CeraSport is not commercially available and uses rice-sugar instead of table sugar. By putting athletic, college-aged men through a series of field tests over three consecutive weekends and feeding them just an ion drink with no sugar, Gatorade, and CeraSport, will help demonstrate if there is a difference in performance. After a 12-hour fast, all participants will be given a standardized breakfast then will run for 90 minutes will a 40-pound pack, do sets of push-ups, a 40-yard dash, vertical leap and finally, run a mile. During this, weight, and urine output will be measured. Each weekend the participants will be given a different drink and who receives what will be randomized throughout the trials. To make sure all participants are fit enough to complete the protocol, they will be pre-screened with a body-fat percentage measured and endurance test.

The Effects of Short Chain Fatty Acids on the Ability of Listeria monocytogenes to Form Biofilm
Jake Edward Thomas
Introduction. Listeria monocytogenes is a common food borne pathogen that can be fatal to those who with compromised immune systems. To combat food borne pathogens, short chain fatty acids are added as food to preservatives. Purpose. The purpose of this experiment was to determine the effects of short chain fatty acids (SCFAs) on the growth of Listeria monocytogenes. Specifically, this research looked at the impact of varying amounts of acetate, butyrate, and propionate on the ability of Listeria to grow in a biofilm, both aerobically and anaerobically, in polypropylene (PP) and polystyrene (PS) in microwell plates. Results. Under anaerobic, but not aerobic, conditions, Listeria planktonic growth increased when SCFAs were added in the culture medium. However, I did not detect consistent results when Listeria was growing in the microwell plates. Conclusion. As indicated by these results, Listeria monocytogenes planktonic growth can be increased when grown anaerobically with SCFAs. However, future research is necessary to assess the effects of SCFAs on biofilm growth.

The Effects of State Anxiety on Olfactory Function in Healthy Young Adults
Lauren Taylor Olson
The specificity of the interaction between the olfactory and emotional systems in the human brain remains unclear due to contradictory research findings. Prior studies have found both positive and negative associations between levels of anxiety and odor detection sensitivity, identification ability, and hedonic ratings. To address this lack of conclusive findings, the present study utilized a within- and between-subjects experimental design to investigate the effects of anxiety induction on olfactory threshold, identification accuracy, and hedonic ratings among 40 undergraduate University of Dayton students. The experimental procedure tested several hypotheses regarding changes in measures from baseline to post-induction: Participants in the anxiety induction group will exhibit a significant decrease in post-induction odor threshold scores, compared to baseline scores, while odor threshold scores will remain stable in the control group,. Participants in the anxiety induction group will exhibit a significant increase in their post-induction odor identification accuracy scores, compared to baseline scores, while odor identification accuracy will remain stable in the control group. Participants in the anxiety induction group will rate post-induction neutral odors as significantly more unpleasant compared to control ratings. Understanding the specific effects of anxiety on olfactory perception is critical in expanding the understanding of reactive emotional processes and may help future researchers who wish to study anxiety and emotional dysfunction in relation to perceptual processes.

The Effects of Tsetse Fly Beta 2 Tubulin on the Fruit Fly Axoneme
Elizabeth Marie Kramer
There are constraints on the evolutionary process. A big question is how nature can generate alternate forms of a protein without interfering with its function. The beta tubulin protein of the fruit fly spermtail is an example of a protein that has not evolved for millions of years. The ultimate goal of this research is to determine how it evolves when it does. To do this, we need to first determine if beta tubulin tolerates change by testing the ability of a related but different beta tubulin to support the fruit fly sperm tail. In this case, the goal is to determine if Glossina morsitans (tsetse fly) beta 2, which is 14 amino acids different, can replace Drosophila beta 2 and generate motile sperm. Using genetic techniques we have expressed tsetse fly beta 2 in the fruit fly Drosophila melanogaster. We now need to selectively mate fruit flies to generate a fly that is a homozygote for both tsetse fly B2 and the null mutation for fruit fly B2. These flies will then be tested for fertility, TEM cross sections will be taken of the testis, and the testis morphology will be analyzed. If the resulting fruit flies are infertile with immotile sperm, then it is likely that the beta protein co-evolved with another component of the sperm tail. Having to wait for a second protein to evolve would slow the evolutionary process and explain why beta 2 has not evolved for 60 million years. But if the resulting fruit flies are fertile, then evolution took a very narrow path that maintained D. melanogaster beta 2 function in the face of 14 amino acid changes.

The Experience of Interaction With and Reporting To the Dean of Students Office among African American Law Students at a Private, Midwestern University
Nikeya Lynn Sharp
The Dean of Students office is a primary advocate for students, providing services and programming that support students in achieving academic and personal success. The office utilizes several departments that it houses as means to connect with and support students. These resources include the offices of Advocacy and Intervention, Community Standards and Civility, Sexual Violence Prevention Education, LGBTQ+ Services, and the Center for Alcohol and Other Drug Resources and Education. Methods for reaching out to and engaging students within each of these offices look different, but all of them include educational programming and unique supports for students. Ideally, these resources would be utilized by all students; however, there seem to be sub-populations of students who tend to take advantage of these services less frequently. One such sub-population is African American law students. Williams (2000) found that African Americans have difficulty reaching out for help from resources due to the fear of being labeled on top of current race related stigmas (p. 243). This purpose of this qualitative, survey research study is to explore the experiences of reporting to and interaction with the Dean of Students office, or reasoning for the lack thereof, among African American law students at private, religiously-affiliated, mid-sized, Midwestern research university. The findings of this anonymous online survey provide helpful indicators for how we can better support these students and ensure they are receiving adequate and equitable support. Having a case management position located within the university Law School could make students more inclined towards reporting concerns of crisis as well as feel more supported.

The FUN(gi) Kind of Colonization: effects of micronutrients on mycorrhizal association with little blue stem.
Kiersten Paige Angelos, Beth Margaret Fuchs, Kaitlin Marie Gawkins, Shania E Hurst, Emily E Jones, Ryan William Reihart
Arbuscular mycorrhizal (AM) fungi are ubiquitous throughout the plant kingdom, and particularly important in grasslands. AM fungi deliver mineral nutrients such as nitrogen (N) and phosphorus (P) to plants in exchange for carbohydrates. Despite this important role in N and P cycling, their interactions with micronutrients, like calcium, are largely unexplored. Interactions with calcium (Ca) may be particularly important because of its role in the intracellular signaling system that helps hyphal tip growth. We determined how additions of Ca both alone and in conjunction with N and P affect the colonization rates of AM fungi in little blue stem (Schizachyrium scoparium). This perennial grass is a dominant graminoid in prairies across the US, including our study site, a coastal tallgrass prairie in Texas. Using a carbon steel soil auger (7.2cm diameter), we sampled S. scoparium roots in a large-scale (30m x 30m plots), factorial-designed fertilization experiment that manipulated Ca and N&P (n=8 replicate plots x 4 S. scoparium individuals x 4 treatments=128 total root samples). Each sample was washed to isolate root samples and stained with trypan blue, and we determined AM fungal colonization by quantifying the number of arbuscules, hyphae, and vesicles for each individual. We saw that Ca with N&P had significant effects on the overall rate of AM fungal colonization. We also saw independent effects of each nutrient on the degree of hyphal and vesicle colonization in the roots of S. scoparium. Taken together, these results suggest that AM fungi may benefit from Ca inputs, but this does not extend to an increased positive effect on the plant. Better understanding its role in belowground and aboveground processes is crucial to maintaining ecosystem functioning. This work represents an important first step to understand more fully the effects of micronutrients on mycorrhizal fungi in terrestrial ecosystems.

The Impact of Benzene as a Chaotropic Agent in Surfactant Based Multicomponent Self-Assembling Systems
Sean Ernest Cedeno, Kasia Maria Solomianko
Self-assembly is a fascinating field that provides endless possibilities for chemical manipulation. This experiment investigates what effect benzene has during the self-assembly of micelles in various carbon chain solutions. Upon omission of delivering benzene from the solution, the system displayed the formation of an irreversible liquid crystal relatively quickly. IR spectroscopy was performed on one solution with benzene and one solution without benzene to try to understand what kind of role benzene plays within the system. Upon examination of the IR spectra, there was a clear difference in IR peaks. It was theorized that benzene has some sort of interaction with the tetraethyl orthosilicate (TEOS) that allows the system to form micelles that can reverse when left alone. Future experiments may include investigating the effect of water on the system as well as the effect of stirring on the system.
