Historical Structural Analysis Of The Rileyville Quadrangle, Page County, Virginia, Sydney Fergen

2024 Symposium

The Northwest corner of Virginia, within the Appalachian Mountains, formed during a collision of continents called the Alleghenian Orogeny roughly 250 million years ago(Ma). This event caused tectonic plates to collide, reforming the fractured continental crust back into a new supercontinent, Pangaea. This process took over 100 Ma and closed the Rheic Ocean. These large-scale compressional tectonics had several effects including formation of the Allegheny Plateau and Taconic Mountain range, which has gradually eroded exposing a series of plunging folds and imbricated thrust faults. This poster presents a structural analysis of the Rileyville quadrangle to help decipher regional geologic history …

U/Pb Zircon Ages Of Saltese Upland Conservation Area, Priest River Core Complex, Jessica M. Lawrence, Natalie Potter, Chad Pritchard

2024 Symposium

The Saltese Upland Conservation Area provides a window into the Priest River Core Complex with Lake Hauser gneiss grading to migmatite, garnet-baring amphibolite juxtaposed with felsite to orthogneiss rocks. U/Pb ages from LA-ICP-MS of separated zircon grains show trends very similar to detrital 207Pb/206Pb ages of the Belt Supergroup. The amphibolite displays a much stronger peak at 1.4 to 1.5 Ga , possibly related to the emplacement of Mesoproterozoic dikes. The amphibolite and granitic rocks also contain a number of grains with 238U/206Pb around 60 Ma preserving events from the uplift of the Priest River Complex in the Spokane area. …

Paleohydraulic Analysis Of Megaripples From Outburst Floods In Omak, Washington, Jessica M. Lawrence

2024 Symposium

Located in Omak, Washington atop what is observed to be a gravel point bar are giant current ripples associated with outburst floods that took place during the Pleistocene (O’Connor et al. 2020 and Minard 1985). Thorough breakdown of these giant current ripples was conducted using their geomorphologies associated with stream flow mechanisms for gravel bedforms such as hydraulic radius of cross- sectional area and velocity using Manning’s equation to determine Froude’s Number (USDA 2007). Ripple index associated with ripple wavelength and height was then compared to additional megaripples located throughout Scablands of Washington that have been correlated to the Great …

Synthesis And Analysis Of Borazine Polymers, Kayla M. Besel

2024 Symposium

Plastics and polymers are incredibly useful and ubiquitous in our daily lives but they are incredibly persistent in the environment, killing more than 1.1 million seabirds and animals each year and the global production of plastic has doubled since 1950.¹ A potential path to eliminate this problem is to create polymers that biodegrade or breakdown over time or in certain conditions. Three distinct degradable polymers were synthesized. The synthesis, characterization, and kinetics monitored by UV/Vis over a range of pH’s will be discussed.

Microplastic Accumulation In The Marsh Periwinkle (Littoraria Irrorata), Sarah Keaton, Hannah Lukhard, Eli Windy, Manar Hasan

DePaul Discoveries

Contamination of oceans by microplastics (mm) currently poses a major threat to aquatic and terrestrial ecosystems worldwide. Recent attention towards this issue has raised questions about the extent to which microplastics have accumulated in the environment, and has led to an increase in studies on the effects of microplastics in various organisms. However, levels of contamination in protected natural areas are still largely unexplored, yet can offer an important empirical perspective on the issue. In addition, little is known about the potential effects of microplastics on behavior in the field. This research was conducted within the protected ACE Basin National …

Pharmaceutical contaminants in water are becoming increasingly prevalent. This could have potentially harmful effects on human health and aquatic environments, even at low concentrations. Acetaminophen, the active ingredient of Tylenol ®, was the target compound for this study, and the aim was to determine is presence and concentration in various aquatic samples in and around the city of Cádiz, Spain. It was predicted that acetaminophen would be detected in low concentrations in river water, drain outflow, University of Cádiz saltwater flow, and lagoon water, but undetectable in the University of Cádiz sink water and fountain water. The presence and concentration …

Spatial And Temporal Analysis Of Pm 2.5 Concentrations In Chicago Along The Lakefront Trail Using Wearable Air Quality Sensors, Jacob A. Johnson

DePaul Discoveries

Mass urbanization and transportation practices have resulted in high amounts of air pollution. Air pollution can have detrimental effects on human health causing respiratory issues as well as other health complications. Certain areas of cities experience more exposure to air pollution which can also cause them to have more health issues and lower life expectancy. These areas are often associated with disinvestment and minoritized communities of color. This research explores patterns of air quality related to environmental justice areas using low-cost wearable air quality monitoring sensors attached to a bicycle. Data was collected along the Lakefront Trail stretching from Irving …

A Seasonal Decomposition Comparison Between Forest And Turf Habitats: Implications For Climate Change, Amanda Shirmer

DePaul Discoveries

Decomposition is an essential ecosystem service in which microorganisms breakdown organic matter. This process improves soil health and acts as a vital step in global carbon cycles. In this study, we examined decomposition rates and associated soil properties in turf and forest habitats across summer and fall seasons in order to determine how land management practices and climate change may be altering local decomposition regimes. Our study determined that there was a statistically significant difference between decomposition rates in turf and forest ecosystems (P=0.003) and a significant difference in decomposition rate across season (P

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …

The Impacts Of Urbanization On Soil: The Effect On Decomposition Rates And Microbial Communities, Maximus C. Halekakis

DePaul Discoveries

The anthropogenic impacts of industrialization have left many ecosystems polluted. Soil, being an imperative actor for ecosystem functions, is important to observe under anthropogenic change. My study examined soil organic matter decomposition, microbial biomass carbon(MBC) and the fungal to bacteria ratio(F:B) across an urban-suburban-exurban landuse gradient in San Luis Obispo, California. A cotton strip assay as well as microBIOMETER® testing was performed on three geographic locations in and outside of the city. The cotton strip decomposition acts as an indicator for organic matter breakdown as microorganisms break down the cellulose in the strips causing them to lose mass and tensile …

Disentangling Drivers Of Metacommunity Structure For Small Mammals Throughout Paraguay, William T. Szromba

DePaul Discoveries

Paraguay is home to a unique precipitation gradient, receiving progressively more precipitation from east to west. It has previously been suggested that metacommunity structures for order Chiroptera assemble along precipitation gradients such as this one. Metacommunities have also been shown to assemble along other bioclimatic gradients such as temperature. This study seeks to expand upon other findings by using a larger dataset, partitioned bioclimatic variables, and more mammalian orders. It also seeks to determine how metacommunities assemble along this gradient in Paraguay, investigate the differences between different ecological metacommunity assemblages, and to further understand which bioclimatic variables have the greatest …

Everyday Exposure: A Qualitative Study Of The Impact Of Gun Violence On The Lives Of Depaul Students, Sara Johnson, Hannah Tariq, Jessica Jerome

DePaul Discoveries

This study examined a novel data source: the contents of letters that students wrote to local, state, or national politicians about gun control for a class assignment in order to collect evidence of the impact of direct and indirect gun violence on the lives of DePaul students. For the study, we coded and analyzed 83 de-identified student letters for themes pertaining to the experience of exposure to gun violence and mass shootings. Our findings include a high prevalence of student exposure to direct incidences of gun violence; strong negative emotions surrounding the fear of gun violence intruding into students’ daily …

Increasing The B-Chromatic Number Of Complete Bipartites By Deleting Edges, Daniel Gawel

DePaul Discoveries

A b-coloring of a graph, G=〈V,E〉, is a proper coloring in which each color has at least one vertex that is adjacent to every other color. The b-chromatic number for G, denoted φ(G), is the largest number of colors you can use to make a b-coloring. For most graphs, φ(G), is around the m-index, an upper bound for φ(G) based on the graph's degree sequence. However, for the complete bipartite graph K_m,n, φ(K_m,n)=2 even though the m-index can be arbitrarily large. In this paper …

Exploring Total Graphs Of Complete Bipartite Graphs, Dominic L J Morgan

DePaul Discoveries

In a proper vertex coloring for a graph G, we call a vertex a b-vertex whenever this vertex is adjacent to at least one vertex of every color class. The b-chromatic number of a graph is defined to be the greatest integer k such that there exists a proper coloring on the graph with k colors where there is at least one b-vertex in every color class. This paper is on the b-chromatic number of the total graphs of complete bipartite graphs. We find bounds of the b-chromatic number for the total graphs of complete bipartite graphs and provide …

The B-Chromatic Number Of Super Cycles, Blair E. Johnson

DePaul Discoveries

The b-chromatic number, a characteristic studied in graph theory, was introduced less than 25 years ago, and while some statistics have been gathered of its properties, the b-chromatic number has yet to be explored in many graphs and circumstances. Before the Undergraduate Summer Research Program, I had no exposure to graph theory, let alone b-colorings. Throughout the program, I developed a fundamental understanding of the subject and began to pursue my own research inquiries. While this objective was difficult to attain at the beginning, I learned strategies and methods to hone my ability to delve into different graphs, and soon …

B-Chromatic Number Of The Graph Power Of The Star Graph, Erik Dahlen

DePaul Discoveries

In this paper we focus on the newly introduced b-colorings of a graph G. A b-coloring is a proper coloring such that for each color class, there exists at least one vertex which is adjacent to every other color. The b-chromatic number of a graph G is the largest number k such that G admits a b-coloring with k colors. This paper will introduce the b-chromatic number of some interesting graphs. Several operations of graphs are defined, and the b-chromatic number of those operations are found. All graphs in this paper are simple, connected, …

DePaul Discoveries

Female human bones dated to the 6^th - 8^th century CE were uncovered in Greding Germany after archaeologists discovered a medieval cemetery. Age-at-death estimates have been determined, and data from several techniques are currently being analyzed to learn more about these samples. The purpose of this project is to study the diaphyses of the second metacarpal (mc2) bones excavated using wide-angle x-ray scattering data collected at beamline 1-ID of the Advanced Photon Source at Argonne National Laboratory. The diffraction data were refined using the Rietveld method to obtain lattice (‘a’ and ‘c’) parameter values …

Framing The Path To Fitness: Age Differences In Response To Framed Exercise Messages, Iliya Sherif, David B. Taullahu, Alyssa R. Minton, Joseph A. Mikels

DePaul Discoveries

Physical activity is one of the most protective health behaviors one can engage in, yet 75% of active adults in the US, meaning those who exercise regularly, fall short of the recommended levels of physical activity, with an even greater percentage of older adults living inactive lives, meaning they exercise minimally and engage in prolonged sedentary behavior (CDC, 2019). The goal of the current study was to explore different types of message framing targeted at encouraging older and younger adults to exercise. We recruited older adults (n = 184; Mage = 69.45 years, age range: 65- 80 years) and younger …
