What's In Your Soil? A Comparative Assessment Of Total Lead In Soils In Southwest Side And North Side Chicago Communities, Jennifer Garcia
What's In Your Soil? A Comparative Assessment Of Total Lead In Soils In Southwest Side And North Side Chicago Communities, Jennifer Garcia
DePaul Discoveries
In Chicago, city officials continue to locate polluting industries in predominately Black and Hispanic/Latinx neighborhoods. Lower income families are disproportionately exposed to greater amounts of toxic chemicals such as lead (Pb). While the City of Chicago focuses its effort in removing industrial sites from the North Side, a predominately white community area, sources of industrial pollution are more likely to be found in communities of color. Due to the prevalent sources of Pb on the Southwest side, residential soil is often highly disturbed and contaminated. Pb is a serious neurotoxin, and ingestion or inhalation of Pb contaminated soil and dust …

Optimization Of Dye Molecules For Use In Studying Inflammatory Caspase Enzymes, Josiah D. Stewart, Phasu Sirinit
DePaul Discoveries
Inflammatory caspases are important enzymes in the initial immune response to pathogens. A common method of studying caspase activity is through the use of fluorogenic assays, in which the cleavage of a substrate by an enzyme results in the emission of fluorescence. Fluorogenic assays require the use of fluorophores: molecules that will fluoresce upon the cleavage of a substrate. Different fluorophores have different characteristics, and these characteristics can be analyzed in order to determine which fluorophores will be most suitable for activity assays. Two commercially available fluorophores were compared for use in fluorogenic assays of inflammatory caspases: MCA and EDANS. …

Triangulation And Finite Element Method For A Variational Problem Inspired By Medical Imaging, Tim Komperda, Enrico Au-Yeung
Triangulation And Finite Element Method For A Variational Problem Inspired By Medical Imaging, Tim Komperda, Enrico Au-Yeung
DePaul Discoveries
We implement the finite element method to solve a variational problem that is inspired by medical imaging. In our application, the domain of the image does not need to be a rectangle and can contain a cavity in the middle. The standard approach to solve a variational problem involves formulating the problem as a partial differential equation. Instead, we solve the variational problem directly, using only techniques available to anyone familiar with vector calculus. As part of the computation, we also explore how triangulation is a useful tool in the process.
Insignificant Impacts Of Covid-19 Stay-At-Home Orders On Chicago Air Quality, Adam W.T. Steffeck
Insignificant Impacts Of Covid-19 Stay-At-Home Orders On Chicago Air Quality, Adam W.T. Steffeck
DePaul Discoveries
With the onset of the COVID-19 pandemic, reports of air quality improvements around the world resulting from the stay-at-home orders were widespread. However, for Chicago, no significant air quality improvements occurred despite large reductions in private vehicle transportation due to the lack of commuters. The city of Chicago is a nexus for long-haul transportation by trucks and trains, which did not decrease during the pandemic. These transportation sources use mostly diesel fuel engines and emit NOX, a precursor to tropospheric ozone, and PM2.5, both of which are harmful air pollutants. Using open access EPA air quality …

Sports And The Environment: A Life Cycle Assessment Of Children’S Football And Hockey Equipment, Emma Casey
DePaul Discoveries
Life-cycle assessment (LCA) is a technique that can be used to assess the environmental implications associated with all of the stages of a product’s life, including raw material extraction, product creation, transportation, use, and disposal. This process can be used by designers to develop a more sustainable approach to their product or by consumers to become more informed on the environmental impacts of the product they are purchasing. Since the sporting goods industry and its products have significant environmental impact through energy use and emissions, this study aims to analyze the contribution of the life cycle stages of youth hockey …

Jewelry is unique in that it is not a necessity, yet it holds sentimental and material value to the owner. Jewelry sales in the US have increased throughout time, meaning the demand for gold has almost always been increasing, as well. With more than half of the gold mined going towards the production of jewelry, it is the product with the highest demand of the resource. However, mining for the metals to produce a piece of jewelry, specifically gold, has negative consequences on both the environment and the people working in or living near mines. This study is a life …

United States Population Future Estimates And Long-Term Distribution, Sean P. Brogan
DePaul Discoveries
The population of the United States has always increased year over year. Even now with decreasing birth rates, the overall population continues to grow when looking at conventional models. The present study specifically examines what would happen to the U.S. population if we were to maintain the current birth and survival rates into the future. By 2050, our research shows that the U.S. population will become much older and cease to grow at all.

The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
DePaul Discoveries
While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …

How To Impress: Coordinating A Large Video Data Set For A Collaborative Project, Noah-Kee Marks, Rita Dawod
DePaul Discoveries
Though many different research methods involve mass quantities of video/audio data, there is little discussion of best practices for organization, especially when the research is collaborative. The guidelines we provide here were created while conducting educational research on the IMPRESS project, an integrated metacognitive program for at risk STEM majors at Rochester Institute of Technology (RIT). Our hope is to encourage large-scale, collaborative research of qualitative video data by using our project as an example and providing enough information for readers to make a judgment on the efficacy of this process for their own projects.

Financial need is a major stressor for individuals who are reentering the community after substance abuse and/or incarceration. Family members and friends make up a great majority the support networks from which reentering people can receive financial support. However, that financial support could possibly contribute to drug use when the individual is actively using. The goal of this study was to further understand the implications of material and financial support specifically being transmitted from family members. This study looks at psychosocial predictors in relation to money spent on drugs in the last 30 days of 270 individuals entering substance abuse …

The Effect Of Hydrogen Peroxide On Leishmania Amazonensis Promastigotes, Debra Eluobaju
DePaul Discoveries
Leishmaniasis is a disease caused by the parasite Leishmania. The disease causes lesions to the skin and face; when visceral it becomes fatal to its host. Leishmanias are transmitted through the female blood-sucking sand fly into its mammalian host, where it infects macrophages. Within the macrophages, Leishmania differentiates from a motile, rod shaped, nonvirulent promastigotes to a non-motile, spherical shaped, virulent amastigotes. Differentiation is due to the high temperature of the mammalian host body, in addition to the low pH of the macrophage. In vitro, the cells are differentiated in Graces medium (pH 5.3) at 33◦C. I investigated whether …
