Corrosion Prevention Of Aluminum Alloy, Andrea Brenner Apr 2022

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 Apr 2022

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 Apr 2022

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 Apr 2022

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 Apr 2022

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 ...

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 ...

Ingredient Classification Using Food Ontology, Ricky Flores

Student Research and Creative Activity Fair

A food label provides some of the most crucial information for a food product. The food label is a key resource for many health-conscious consumers for understanding ingredients. It is also vital for individuals to avoid food allergens or help patients follow dietary recommendations. While the food labels in the United States are regulated by the Food and Drug Administration (FDA) many labels contain additional information or statements that are not regulated. Moreover, the food label may be complex or contain terminology that the layperson may not understand. Evidence has indicated that consumers often find nutrition labels confusing, especially when ...

Remote sensing methods provide tools to identify and map non-native plants. Biophysical characteristics of plants can be utilized to recognize and distinguish non-native invasive plants from other native plant species. Kudzu is an invasive plant, which causes economic loss and decreases biodiversity. Moreover, kudzu doubles emission of nitric oxide and increases ozone pollution. The impact of human activities on the spread of noxious plant species like kudzu can be assessed utilizing remote sensing and geographic information systems (GIS) tools. Kudzu spread in the USA was mapped using in situ data including the actual coordinates of kudzu sites. Geographic distribution of ...


Pilot Study Exploring The Impact That Laboratory ​Instruction Has On A Student's Stem Professional Identity​ ​, Datiel Dayani, Dr. Michelle Head Nov 2021

Pilot Study Exploring The Impact That Laboratory ​Instruction Has On A Student's Stem Professional Identity​ ​, Datiel Dayani, Dr. Michelle Head

Symposium of Student Scholars

STEM professional identity serves as one lens through which researchers have used to study factors that influence achievement in chemistry courses and persistence in a STEM major. The literature has proposed that the high attrition rate among STEM majors may result from the student’s evolving professional identity, motivational factors, and how they correlate a STEM career to their future aspirations. There is limited insight into how laboratory classes and teaching practices affect a student’s professional identity development. To investigate this, this study employed James Marcia’s identity development theory to understand the relationship between a student's identity ...
