A Numerical Solution Of A Model Of Diabetes, Malle R. Schilling, Nathan D. Volk Apr 2016

A Numerical Solution Of A Model Of Diabetes, Malle R. Schilling, Nathan D. Volk

Stander Symposium Posters

Many researchers use mathematical models to understand and predict the behavior of biological systems. In this work we consider a mathematical model for diabetes mellitus presented by Hussain and Zadeng to study a metabolic disease for the regulation of glucose in the body by pancreatic insulin. The mathematical models consists of two ordinary differential equations for glucose concentration and insulin concentration. In particular, this study attempts to numerically solve the model using the Runge-Kutta methods of order 2 and 4. We will also perform a qualitative analysis on the behavior of the system

Capture Ratio Analysis And The Materials Sector Xlb: A Performance Review For 2010-2015, Nicholas C. Jacobs

Stander Symposium Posters

The materials sector performance has had a challenging time over the last few years. A slow down in China and Europe certainly have been contributing factors in XLB's weak performance. In this study, I evaluate a portfolio weighting model based on capture ratios. The covariance in price peformance between large-cap stocks in the materials sector and the market (S&P 500). In this study I use a concentrated portfolio of the 10 biggest cap-weighted stocks in XLB and weight their position in the portfolio by upside/downside capture ratios. I then test the following hypotheses; 1.)The 10 materials stocks portfolio weighted by upside/downside capture ratios outperforms the market (S&P 500) 2.) The upside/downside capture ratio weighted concentrated portfolio of materials stocks outperforms XLB and 3.) The concentrated portfolio of materials stocks ...

Honor's Thesis Proposal: Effects Of Tactile Versus Electronic Games On Attention, Distraction, And Understanding, Samantha A. Malick

Stander Symposium Posters

The ability to attend to relevant information and resist attention to distractors is important for children’s cognitive development. Difficulties with attention can impede memory development and impact learning. Much has been written in the news about the impact of electronic media on children’s development of attention skills, but little research has been done explicitly comparing children’s attention to relevant information and resistance to distractions across activities that are presented in either tactile or electronic format. The goal of this study is to compare levels of attention and distraction among preschool-aged children while they engage in a common ...


Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin, Thomas L. Bennett Apr 2016

Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin, Thomas L. Bennett

Stander Symposium Posters

Porphyrins are a specific class of aromatic, heterocyclic compounds that are either naturally occurring or artificially synthesized. Porphyrins have demonstrated robust antibacterial properties, which arise from the generation of singlet oxygen. However, most porphyrins are photodynamic, meaning they require activation by light at an optimal wavelength. A novel porphyrin, developed by Dr. Shawn Swavey (UD Chemistry Department) has shown exceptional antibacterial efficiency against Pseudomonas aeruginosa, even without photoactivation. As P. aeruginosa infections are often the root cause behind lung diseases, such as cystic fibrosis, identifying a way to safely control bacterial presence is a major concern. The ability of this ...

Stander Symposium Posters

How do you dispose of your used car tires? Although answering this on an individual level doesn’t seem to be hard, the sheer amounts of old tires disposed of as a byproduct of a growing car market in the United States have grown to make a significant impact on the environment. Each year, over 350 million tires are consumed and only about 70% of the accruing waste is properly recycled at their end of life. The storage of tires in landfills, or improper methods of disposal, such as burning and waterbody displacement causes hazardous emissions and health problems. For ...

Dissecting The Sex-Dependent Neurochemical Effects Of The Rapid-Acting Antidepressant Drug Ketamine With In Vivo Brain Microdialysis In Mice, Jonathon P. Sens, Connor F. Thelen

Stander Symposium Posters

Major depression is a devastating mental disorder that affects nearly 20% of the world’s population. Notably, women experience major depression at roughly twice the rate of men and respond differently to different types of antidepressant drugs. However, the neurobiological mechanisms underlying this sex-differentiated responsiveness remain a largely neglected area of experimentation with current treatments based almost exclusively on research conducted in males. Most importantly, currently marketed antidepressant drugs take anywhere from weeks to months in order to elicit their therapeutic effects, thus leading to increased drop-out rates. Ketamine is a unique, rapid-acting antidepressant drug that alleviates depressive symptomatology in ...


Producer Prices, Cost-Push-Inflation And Stock Market Returns, Anthony J. Bello Apr 2016

Producer Prices, Cost-Push-Inflation And Stock Market Returns, Anthony J. Bello

Stander Symposium Posters

Although the Fed looks at the Consumer Price Index (CPI) and the Personal Consumption Expenditure index (PCE) as the key measures of inflation, in this study I focus my attention on Producer Prices (PPI) as a leading indicator of inflation in final goods produced. I want to test three hypotheses. First there is a high pass through rate for prices in the 4 basic stages of production identified by the Bureau of Labor Statistics (BLS). Using regression analysis to measure the pass through rate, I expect the b coefficients to be greater than zero and close to one. This would ...

Developing Trend Equations For Cpi:As Empirical Analysis 2001-2015, Daniel J. Whitehead

Stander Symposium Posters

Since the 2008 recession, overall inflation as measured by CPI has been perceived to be almost non existent. In recent months, however, inflation is picking up, which in a perverse sort of way is seen as good for the economy. The purpose of this study, therefore, is to more clearly understand CPI trend inflation. To that end, I looked at a long term trend, 2001-2014, two intermediate term trends, 2001-2007 and 2009-2014 and a short term trend, 2013-2014. Monthly and yearly linear trend equations were developed for the long and intermediate term time periods. For the shorter time period both ...


The Use Of A Molecular Probe To Investigate The Details Of Pria Helicase Function, Luke F. Bugada Apr 2016

The Use Of A Molecular Probe To Investigate The Details Of Pria Helicase Function, Luke F. Bugada

Stander Symposium Posters

During DNA replication in both eukaryotic and prokaryotic cells, the replication machinery (replisome) invariably encounters structural DNA damage, an event that can result in disbanding of the replisome and the creation of a collapsed replication fork. In order for DNA replication to continue, the replisome must be reloaded onto the DNA strand, a process that often begins with unwinding of double-stranded (duplex) DNA by the primosome protein PriA. Little is known about the mechanism through which PriA unwinds DNA and begins replisome recruitment. We seek to shed new light on this mechanism through the use of a PriA inhibitor, compound ...


Role Of Axial Patterning Genes In Growth Regulation During Eye Development, Neha Gogia Apr 2016

Role Of Axial Patterning Genes In Growth Regulation During Eye Development, Neha Gogia

Stander Symposium Posters

An important question in developmental biology is that how axial patterning genes work with growth and patterning to form any three-dimensional organ. In any multicellular organism, Organogenesis, requires axial patterning i.e. formation of Antero-Posterior (AP), Dorso-Ventral (DV), Proximo-Distal (PD) axes. Any deviation in these axes during development leads to genetic birth defects. We use Drosophila melanogaster (a.k.a fruit fly), eye as our model. As the genetic machinery between flies and human is conserved, any insights generated in flies can be extrapolated into humans. In Drosophila, DV patterning marks first lineage restriction event where expression of dorsal, ventral ...

Changes that graduate international students face in acculturating to U.S. educational environments can often impact the ways they engage on campus, and their subsequent personal and career success. This poses the question of “What are the key themes that institutions can build upon to better support and encourage their growth?” In conducting a mixed-methods study on the lived experiences of graduate students from India, main findings suggested that mentoring relationships, social ties, and factors of perception were crucial to influencing students’ academic and social engagement.


Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities, Sydney E. Kirk Apr 2016

Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities, Sydney E. Kirk

Stander Symposium Posters

DNA damage can cause the process of DNA replication to stall and this can lead to dissociation of the DNA replication enzymes from the DNA. In bacteria, a protein called PriA recognizes this, unwinds a portion of duplex DNA at the site where replication stalled, and reloads the replication enzymes to restart DNA replication. PriA has multiple structural domains that are closely associated with one another to give rise to a compact globular protein. The winged helix domain, however, is connected to the remainder of the protein by a long, flexible portion of polypeptide, akin to a tether. I examined ...

Greek Life And Catholic Universities: Do The Values Of Greek Life Match With Those Of The Catholic Church?, John A. Goebel

Stander Symposium Posters

Greek Life organizations face many negative stipulations across the United States due to several allegations of disrespectful actions. Due to these negative actions, there are Catholic institutions across the United States that do not allow Greek Life organizations on their respective campus. Such reasons Catholic institutions give is that Greek Life is not needed on campus for students to live out Catholic values. Instead, students have service, special interest and sports clubs to join to live out Catholic values. As a student apart of Greek Life on the University of Dayton’s campus feel that the values between Greek life ...

Stander Symposium Posters

Listeria monocytogenes is an infectious bacterium that is known to cause severe diseases in people who are pregnant, elderly, or generally immunocompromised through consumption of contaminated food products. To help develop preventative strategies to protect these high-risk individuals, our lab focuses on the approach of enhancing the chemical barrier naturally existing in the intestinal tract to block L. monocytogenes from interacting with the human intestinal epithelium and causing fatal infections. The chemical environment inside the human intestinal lumen is rich with fermentation acids produced by the endogenous microbes. In my research project, I tested the efficacy of propionic acid, one ...

Effects Of Body Weight Loading On Arch Height, Anastasia Bjelopetrovich

Stander Symposium Posters

Foot functionality is integral to normal human locomotion. The most commonly assessed area of the human body studied during locomotion is the medial longitudinal arch and its deformation. The Arch Height Index Measurement System (AHIMS) is the most reliable tool to measure this arch. This system typically measures arch deformation in two baseline conditions, sitting and standing. The sitting condition is considered unweighted and approximately 10% of a person’s body weight. The standing condition is considered a loaded condition and represents 50% of body weight. The first aim of this study was to see if the baseline measurements traditionally ...

Can The Color Red Improve Men’S Perceived Mate Value?: Examining The Interactive Effects Of Facial Masculinity And Color On Female Evaluation Of Potential Mates, Alejandro Trujillo

Stander Symposium Posters

We manipulated facial masculinity (masculine-morph/feminine-morph) and color (red/white) through two independent studies—one in-lab at the University of Dayton and one online using Amazon’s MTurk—to examine its effect on social status and attractiveness for men when rated by women. We specifically aimed to see if the color red could serve a compensatory effect for feminine-faced men, who were least likely to be found attractive by women at peak fertility. When paired with red, women rated the masculine and feminine faces higher in social status. Through this increase in social status, the color red was also able ...

The TolC protomer of the AcrAB-TolC efflux pump in Escherichia coli was targeted in a virtual screen for novel small molecule inhibitor compounds. PyRx AutoDock Vina was used to virtually dock the various small molecules to the TolC protein and rank the compounds based on favorable binding energies. Five lead-compounds from the virtual screen were ultimately selected for in vivo ...


Design And Prototyping Of A Variable Geometry Extrusion Die To Exhibit Significant Alteration In Shape, David C. Bell Apr 2016

Design And Prototyping Of A Variable Geometry Extrusion Die To Exhibit Significant Alteration In Shape, David C. Bell

Stander Symposium Posters

Extruded parts are conventionally made by forcing melted plastic through a steel die having a fixed opening that matches the shape of the part. Plastic parts made by extrusion include weather stripping, PVC pipe, and composite lumber. Variable geometry dies can change their opening shape during the extrusion process. Developing shape-changing dies technology offers the possibility of making parts with varying cross-sections that currently need to be made through injection molding. This is desirable as, compared to molding, extrusion tends to be faster and less expensive. Variable geometry extrusion dies have been designed and prototyped by the University of Dayton ...
