Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities
Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities
Stander Symposium Projects
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 …

Stander Symposium Projects
Memristor,the forth fundamental circuit element, has opened new phase in the realm of thin film semiconducting device. The non-volatility of memristors, used as Resistive switching RAM, is promising for applications such as DRAM, hard disks etc. The implementation of a memristor device with Tungsten Oxide (WOx) is presented in this work. The presentation addresses fundamental electrical characterization of the memristor devices for their switching performance. Resistive switching in WOx is bipolar in nature. The Pd/WOx/W made memristors become more conductive (resistive) when applied with a positive (negative) bias voltage. The conductance or resistance change is controlled by the re-distribution of …
A Portfolio Weighting Strategy For A Portfolio Of 9 Large Cap Healthcare Stocks: The Case For Capture Ratios, 2010 - 2015
Stander Symposium Projects
The Capital Asset Pricing Model (CAPM) indicates that individual stocks are systematically influenced by overall price movements in the market. One way of measuring these systematic movements is through capture ratios. In this study I utilize upside/downside capture ratios to develop portfolio weights for 9 large cap Health Care stocks which make up the largest overall weight in the Health Care Sector XLV. I test the following hypotheses: (1) The upside/downside capture ratio weighted portfolio outperforms the market (S&P 500), (2) the upside/downside capture ratio weighted portfolio outperforms XLV. (3) The performance of the upside/downside capture ratio weighted healthcare portfolio …

Finding Physicians Fast: Making Finding A Doctor Easier For Esl Students
Stander Symposium Projects
In the realm of healthcare, it is often difficult to decipher how to locate personal and primary physicians. Those living in the United States are familiar with the role of family care physicians, however, individuals who have immigrated to the U.S. may not fully understand how to find a family physician. The topic of family physicians is important because many other countries do not have primary care physicians that require appointments. For our project, we took two documents that tested at a reading level of 12th grade. We did this by testing the original documents with the SMOG test and …
Producer Prices, Cost-Push-Inflation And Stock Market Returns
Producer Prices, Cost-Push-Inflation And Stock Market Returns
Stander Symposium Projects
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 …
Effect Of Combination Ice And Compression Socks On Resting Calf Blood Flow In Trained Male Athletes
Effect Of Combination Ice And Compression Socks On Resting Calf Blood Flow In Trained Male Athletes
Stander Symposium Projects
Compression socks are common tools that are utilized in the realm of athletics. The purpose of the compression is to increase blood flow to the lower extremities, thereby increasing oxygen and energy sources needed for increased skeletal muscle function and/or recovery. Recently, a product has been marketed that combines the compression element and cryotherapy, with the goal being increased blood flow to the lower extremities while reducing inflammation post-workout to quicken recovery. However, to our knowledge, direct measures of blood flow using this type of product have not been performed. Thus, this study looks at the effects of compression with …
Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin
Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin
Stander Symposium Projects
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 …
Creating Value Through Sustainable Manufacturing
Creating Value Through Sustainable Manufacturing
Stander Symposium Projects
To support movement toward a more sustainable worldview, increasing manufacturing efficiency or productivity to improve business profitability and return to shareholders alone is no longer sufficient. Today, leading manufacturers employ business practices that generate sustainable value—that is, creating economic, environmental, and societal value for all stakeholders. Progressive company culture, environmental and energy management systems, carbon neutrality, and becoming landfill free are all valuable outcomes of sustainable manufacturing. This poster outlines the the value of these outcomes as well as methods to achieve sustainable manufacturing.
Role Of Axial Patterning Genes In Growth Regulation During Eye Development
Role Of Axial Patterning Genes In Growth Regulation During Eye Development
Stander Symposium Projects
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 fate selectors forms …
Design And Fabrication Of Fourier Spectral Filter Array For Multispectral Imaging
Design And Fabrication Of Fourier Spectral Filter Array For Multispectral Imaging
Stander Symposium Projects
Multispectral imaging has the capability to identify the state of objects based on their spectral characteristics. These are features not available with conventional color imaging based on metameric RGB (red, green and blue) colors alone. Current multispectral imaging systems use narrowband filters to capture the spectral content of a scene, which necessitates different filters to be designed and applied for each application. We have demonstrated the concept of Fourier multispectral imaging which uses filters with sinusoidally varying transmittance by time multiplexed switchable filter array in our previous paper [1, 2]. In this paper, we designed and built a five channel, …
Research Exercise: Tired Of Rubber Landfills: From Environmental Hazard To Sustainable Use Potential Of Discarded Tire Materials
Stander Symposium Projects
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 instance, …

Stander Symposium Projects
The purpose for this project was to redesign a past General Chemistry Laboratory experiment with emphasis on student learning objectives in support of lecture material. The experiment was first introduced into the second semester CHM124L course in 1997 as “Preparation and Investigation of Salt Solutions”. For the Fall 2016 curriculum, the modified experiment will be conducted in the first semester General Chemistry course CHM123L as “Equilibrium of Salt Solutions”. This experiment was chosen for modification because the concept of equilibrium, especially when applied to pH of salt solutions, is one that many students find difficult to understand. Experiencing the concept …
Portfolio Weighting Strategies For A Concentrated Portfolio Of Consumer Discretionary Stocks: An Empirical Analysis, 2010-2015
Stander Symposium Projects
Recent interest by investment managers in Portfolio Weighting Strategies other than market capitalization has led to a rapid increase in fundamental based indexing. In their study I use the price dynamics of firms relative to the market (S&P 500) to weight a 10 stock portfolio of Consumer Discretionary firms. The weighting model is based on the capture ratio of the price changes for each stock compared to the S&P 500. In particular, an upside/downside capture ratio is developed for each stock based on a years worth of daily price changes. The following hypotheses are tested: 1) Firms with higher upside/downside …
Effects Of Body Weight Loading On Arch Height
Effects Of Body Weight Loading On Arch Height
Stander Symposium Projects
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 taken …
Portfolio Weights And Capture Ratio Analysis: A Look At Performance In The Consumers Staples Sector 2010-2015
Stander Symposium Projects
Since the recession in 2008, the stock market has experienced periods of extreme volatility, with market moves of 200-400 points on almost a daily basis. One sector that should do well when market volatility is high and rising is consumer staples. In this study I use a dynamic pricing model to determine the portfolio weights for the 10 largest value weighted stocks in the consumer staples sector. The model relies on the upside/downside Capture Ratios (U/D) for each stock to calculate the portfolio weights and dollar investment in each stock. I test the following hypotheses: (1) Stocks with higher U/D …
Robust Nonlinear Adaptive Control For Longitudinal Dynamics Of Hypersonic Aircraft Vehicle Model
Robust Nonlinear Adaptive Control For Longitudinal Dynamics Of Hypersonic Aircraft Vehicle Model
Stander Symposium Projects
A hypersonic aircraft vehicle is a highly complex nonlinear system, which includes uncertainties in the dynamics. This paper presents the design of robust nonlinear adaptive control for a hypersonic aircraft vehicle model. The complexity of the dynamic system is considered into the design structure of the control in order to address robustness issues. Design of a robust control system should decouple the longitudinal and lateral dynamics to handle the flight of hypersonic vehicle under certain specific conditions. In this paper, we only consider longitudinal dynamics, which are divided into aircraft speed subsystem and flight-path angle subsystem. A robust control design …
Inflation Trends In Personal Consumption Expenditures, 2001-2015
Inflation Trends In Personal Consumption Expenditures, 2001-2015
Stander Symposium Projects
The Federal Reserve, as a key element in its monetary policy, uses a 2% target inflation rate to determine if the federal funds rate needs to be increased. The purpose of this study is to evaluate long, intermediate, and short term trends in inflation to determine if the inflation policy objective has been reached. My inflation metric is Personal Consumption Expenditure (PCE) and the period of analysis is 2001-20015. I develop linear trend equations for both PCE and PCE less food and energy using the b coefficients from the regressions as a proxy for the PCE inflation rate. Out of …
Avoiding The Guillotine: The Need For Balance And Purpose In Determining Fundamental Rights Under The Fourteenth Amendment
Stander Symposium Projects
This paper argues the need for a balanced approach between traditionalism (including history) and rationalism to determine fundamental rights under the Fourteenth Amendment of the U.S. Constitution. The issue of how to determine fundamental rights has intrigued the Supreme Court of the United States since 1798. The Supreme Court has desired an “objective” approach to determine what rights are “fundamental.” However, the Supreme Court has had difficulty finding an objective approach. This is because, as E.O. Wilson and Joshua Greene observed, rights are naturally subjective creations of an individual’s values. Thus, any test to determine fundamental rights will be subjective …
State Initiatives, Ballot Language, And The Media: Do They Overlap?
State Initiatives, Ballot Language, And The Media: Do They Overlap?
Stander Symposium Projects
State Initiatives are seen throughout every state, some more than others, but every election brings them. However, not every election is equal when it comes to turnout, depending on if it is a presidential or midterm year. Some are given more media attention, some are given minimal attention, if at all. The fundamental question is what role doe’s media play in turnout during elections and does any amount of roll-off occurs during presidential or governor’s elections? Does this poll-off or turnout have to do with media (or lack of) attention, or is there something more going on? Besides looking at …
Identification Of Potential Acrab-Tolc Efflux Pump Inhibitors In Escherichia Coli Using An Ethidium Bromide Method.
Stander Symposium Projects
Many bacteria are known to exhibit antibiotic resistance through overexpression of efflux pumps. In this experiment, inhibition of a bacterial efflux pump through the physical binding of small molecule inhibitor compounds was explored as a way to combat substrate expulsion. 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 …
Wage Costs And Inflation Trends: An Empirical Analysis 2001-2015
Wage Costs And Inflation Trends: An Empirical Analysis 2001-2015
Stander Symposium Projects
Rising wage costs have often been used as a leading indication of inflation in national economies. In the US since the 2008 recession wage costs growth has, to say the least, been erratic with no discernible upward trend. In 2015, however, wage cost growth showed some signs of picking up steam suggesting that overall spending in the economy will likely pick up. In this study we examine trends in the employee cost index (ECI) from 2001 to 2015, the long term trend period, and 2009 to 2015, an intermediate term period after the 2008 recession. Linear trend equations are developed …
Examining Factors Associated With High Leadership Self-Efficacy Among International Women College Students In The U.S.
Stander Symposium Projects
Leadership self-efficacy is an area of self-efficacy related to the level of confidence one has in his or her knowledge, skills, and abilities to lead others (Bandura, 1997). When leadership self- efficacy is placed within the context of student development, it has the ability to contribute to or negate from a student’s motivation to persist and succeed in leadership associated tasks (Bandura, 1993; Stage, 1996). The goal of this research is to explore how international female undergraduate students perceive their leadership abilities in relation to their personally constructed definition of leadership. Through qualitative interviews with six international female undergraduate students, …
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
Stander Symposium Projects
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 to indirectly increase the physical …
