Determination Of Nitrate In Aqueous Media, Ebony Arauz Tellez, John Bohannon, Rebecca Mills, Virginia Tam, Isabelle Villarreal, Melissa C. Rhoten

Fall Showcase for Research and Creative Inquiry

Determining the amount of inorganic ions in aqueous media is important in the food industry and environmentally. In the environment high levels of ions like nitrate (NO₃^-), nitrite (NO2^-), and phosphate (PO₄^3-) can lead to unhealthy conditions for aquatic species. Similarly, high levels of nitrate and nitrite can cause health issues in humans. One method for determining nitrate levels in aqueous samples involves reducing the nitrate species to nitrite via a redox reaction with finely divided zinc powder followed by conversion to a diazonium salt and complexation with 1-napthylamine to form a …

Evaluating Our Reliance On Rare Earth Minerals And Platinum Group Metals Over The Period Of 2012 To 2021, Ryan Smith

Fall Showcase for Research and Creative Inquiry

Rare Earth Elements (REE’s) are minerals used in our everyday lives. They can be found in our household appliances, phones, computers, cars, as part of wind turbines and solar panels. The US relies on imports of these rare earths from several other countries (e.g. China, Estonia, Malaysia, and Japan) as we cannot mine a majority of the minerals (e.g. cerium, lanthanum, europium, etc) domestically. Since the year 2012, the US has imported approximately 3,000 metric tons of rare earths, and in recent years, this number significantly increased. As of 2021, the US now imports approximately 43,000 metric tons of rare …

Is It Useful? Orthophosphate Mapping Of An Excavated Cellar Of A Mid 1700’S Tavern In New London Va, Thomas M. Bender, Randy Lichtenberger

Faculty Publications and Presentations

The partially backfilled cellar of Mead’s Tavern (VDHR # 015-0120) a circa 1760’s building in New London Virginia, was studied by orthophosphate (PO₄³) mapping of the recently exposed, culturally sterile, subsoil floor. Prior studies of the cellar had exposed a hearth along with features that were speculated to be wall partitions for subdivision of the cellar. The full intended purpose for those exposed features is unknown. To further probe that exposed subsoil prior to a major engineering stabilization of the tavern’s foundation, a chemical mapping of surface PO₄^3- levels in the cellar was done. The …

Since we are living in a digital age, the need to protect ourselves and those who are vulnerable to cyber-attacks is paramount to prevent cyber attacks that steal information such as banking accounts and important sensitive information.

Our research team extensively investigated the five aspects of cybersecurity such as identity, protection, detection, and response. By conducting various interviews with cybersecurity professionals, we gathered information about these five aspects for example security intelligence or security operations and response, (thread hunting, response orchestration) identity access management, (identity management, and data protection), and risks (risk perspective). Our main goal is to look into …

The Living Breakwaters Pdr Efforts: Conceptual Scheduling, Calvin O. Walters Jr.

Publications and Research

On October 29, 2012, Superstorm Sandy caused nearly $19 billion in damages in New York City including 69,000 residential units across the five boroughs. This disaster precipitated a post-disaster-rebuilding (PDR) project including roughly $4.2 billion in a Community Development Block Grant allocated towards PDR projects. A portion of the grant was used to construct a living breakwater in Tottenville, Staten Island, consisting of a resiliency approach to risk reduction through erosion prevention, wave energy attenuation, and enhancement of ecosystems and social resiliency to improve resistance to storms for the community of Tottenville. The ridges of each breakwater are designed with …

To Adopt Blockchain Technology Or Not: Is The Decision-Making Process Immune To Covid-19?, Rebecca Jauch

Corrosion Prevention Of Aluminum Alloy, Andrea Brenner

Symposium of Student Scholars

Aluminum alloy (Al-alloy) is a widely used metal in construction, aerospace, aviation, and other necessary fields due to its lightweight and tweakable properties. However, corrosion is inevitable on metals and alloys, and that causes millions of dollars of revenue loss every year. Therefore, we propose to research fabricating coating to prevent corrosion on Al-alloy. This study uses an iron-based metal-organic framework (MOF) and polyurethane (PU) based composite coating to prevent corrosion on the Al-alloy. The makeup of the composite material is changed by varying the percentage of MOF. In addition, a binder is also used to enhance the homogenization between …

Rotoscoping Image Processing, David J. Blackstone

Student Scholar Showcase

I wrote a program to perform rotoscoping image processing. Rotoscoping is an animation technique that is used to turn real images into cartoon images. This is a lengthy process to do by hand, taking hundreds of hours. To make this job easier, I have written a program to do automated rotoscoping. This program uses many algorithms and techniques such as edge detection, blurring, directional detection, and edge tracking. What once would take hours by hand, takes seconds!

Mapping The Impact Of A Trailway System On The Amount Of Trash Present Within Two Watersheds Of Lynchburg City, Virginia, Lillian Smith

Student Scholar Showcase

Transportation of trash debris within water systems is a prominent occurrence which has been linked to natural and artificial processes such as wind, rain, and littering. Recreational areas, such as activities along greenway trails, have been determined to be a source of debris found in waterways. This study examines whether the presence of an established recreational trail system limits trash accumulation in the entirety of a watershed. Trash data collected at Blackwater Creek, which contains an established trail system, was compared to trash data collected at Fishing Creek, containing a non-established trail system, to answer this hypothesis. A distance of …

Mathematical Model Of Devil Facial Tumor Disease (Dftd) Spread In Tasmanian Devils, Abigail Collins

Scholars Week

Applications of disease models can lead to insight on spread of diseases, population movements, and wildlife health safety. This exploration of mathematical models sought to determine the spread of wildlife disease, specifically devil facial tumor disease (DFTD). Tasmanian devil populations have been negatively affected by DFTD. The basic SIR disease model was modified to better fit the spread of DFTD, along with a network model to inspect the rate of infectivity. It was found that the population of Tasmanian devils will continue to decrease in size and multiple populations are connected to each other. Models of wildlife disease have the …

Probing Small Heat Shock Protein Chaperoning Activity Through The Interaction Between Myoglobin And Guanidine Hydrochloride, Jacob Mcdowell

Celebration of Research

Myoglobin is a small biological protein found in most muscle tissues. When in the proper form (native/folded), myoglobin can serve its primary function: binding oxygen. However, like all proteins, myoglobin can denature through a variety of processes into a form that no longer binds oxygen. One denaturant, guanidine hydrochloride (GuHCl), is the biological product of protein metabolism. Another class of biological proteins is small heat shock proteins (sHSPs), which have the function of chaperoning other proteins to prevent the denaturing process. Previously, in physical chemistry lab, we explored the GuHCl-induced denaturing of myoglobin. Former Northwestern students used fluorescence correlation spectroscopy …

Participation In Curriculum And Cultural Ambassador Group To Enhance Student Belongingness, Jake Tuft, Jacob Schvaneveldt

Annual Research Symposium

COVID-19 negatively impacted students' abilities to participate in live, in-person events; students were unable to interact with peers or build relationships critical to success and well-being. Quarantine, social distancing and video conferencing did not create this problem however, it simply amplified the fact that dental students seemingly lack camaraderie and a sense of belongingness. The Curriculum and Cultural Ambassador group was created to allow students to bond over shared goals in the hopes of improving their experiences within dental school. This group gives students the ability to “Be the Change” on campus and enact real-time change to foster a sense …
