Planning, Engagement And Construction Of Blue-Green Systems: Creating Connected And Multi-Beneficial Solutions For The Road Right-Of-Way In Vancouver, Dr. Tugce Conger, Connor Redman

Salish Sea Ecosystem Conference

In 2019, Vancouver City Council adopted the Rain City Strategy, committing to capture and clean 90% of rainfall that falls within the City, and in doing so, transforming urban watersheds for present and future generations. At the same time, Vancouver is continuing to densify. With increasing density, there is a growing demand for space in the road right-of-way –rainwater management, more and larger servicing utilities, vehicles, transit, bikeways, and wider sidewalks are all competing for spaces. Blue-Green Systems (BGS) are an emerging green infrastructure typology that help the City to meet multiple objectives in the same space. The City and …

How To Guard An Art Gallery: A Simple Mathematical Problem, Natalie Petruzelli

The Review: A Journal of Undergraduate Student Research

The art gallery problem is a geometry question that seeks to find the minimum number of guards necessary to guard an art gallery based on the qualities of the museum’s shape, specifically the number of walls. Solved by Václav Chvátal in 1975, the resulting Art Gallery Theorem dictates that ⌊n/3⌋ guards are always sufficient and sometimes necessary to guard an art gallery with n walls. This theorem, along with the argument that proves it, are accessible and interesting results even to one with little to no mathematical knowledge, introducing readers to common concepts in both geometry and graph …

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

Foldamers Reveal And Validate Therapeutic Targets Associated With Toxic Α-Synuclein Self-Assembly, Jemil Ahmed, Tessa C. Fitch, Courtney M. Donnelly, Johnson A. Joseph, Tyler D. Ball, Mikaela M. Bassil, Ahyun Son, Chen Zhang, Aurélie Ledreux, Scott Horowitz, Yan Qin, Daniel Paredes, Sunil Kumar

Chemistry and Biochemistry: Faculty Scholarship

Parkinson’s disease (PD) is a progressive neurodegenerative disorder for which there is no successful prevention or intervention. The pathological hallmark for PD involves the self-assembly of functional Alpha-Synuclein (αS) into non-functional amyloid structures. One of the potential therapeutic interventions against PD is the effective inhibition of αS aggregation. However, the bottleneck towards achieving this goal is the identification of αS domains/sequences that are essential for aggregation. Using a protein mimetic approach, we have identified αS sequences-based targets that are essential for aggregation and will have significant therapeutic implications. An extensive array of in vitro, ex vivo, and in vivo assays …

Topological Data Analysis With Mapper, Gretchen Langenbahn

Honors Projects

This project is an introduction and overview of Mapper. Mapper is a method of high dimensional data visualization. Data visualization is a very important part of data analysis as it allows for further interpretation and exploration of data.

Carbohydrate Metabolism In Bacteria: Alternative Specificities In Adp-Glucose Pyrophosphorylases Open Novel Metabolic Scenarios And Biotechnological Tools, Jaina A. Bhayani, Maria Josefina Iglesias, Romina I. Minen, Antonela E. Cereijo, Miguel Ballicora, Alberto A. Iglesias, Matias D. Asencion Diez

Chemistry: Faculty Publications and Other Works

We explored the ability of ADP-glucose pyrophosphorylase (ADP-Glc PPase) from different bacteria to use glucosamine (GlcN) metabolites as a substrate or allosteric effectors. The enzyme from the actinobacteria Kocuria rhizophila exhibited marked and distinctive sensitivity to allosteric activation by GlcN-6P when producing ADP-Glc from glucose-1-phosphate (Glc-1P) and ATP. This behavior is also seen in the enzyme from Rhodococcus spp., the only one known so far to portray this activation. GlcN-6P had a more modest effect on the enzyme from other Actinobacteria (Streptomyces coelicolor), Firmicutes (Ruminococcus albus), and Proteobacteria (Agrobacterium tumefaciens) groups. In addition, we …

Synthesis, Characterization, And Thermal Investigation Of Metal Phosphites And Potential Implications For Astrobiology, Kimberly Faye Meyberg

Master of Science in Chemical Sciences Theses

The role of phosphorus in biochemistry is well understood. However, the route by which phosphorus was incorporated into early biomolecules on the prebiotic Earth is uncertain. Phosphate, the most prevalent species of phosphorus found in Earth’s geological record, is insoluble and unreactive with organics in aqueous environments. While the most abundant biogenic elements (C, N, H, O, and S) can be found in a volatile phase under terrestrial conditions, phosphorus cannot, suggesting that minerals must have been the main sources of phosphorus on the early Earth. One possible explanation is that phosphite was a major source of reduced, reactive phosphorus …

Sharp Inequalities Of The X-Ray Transform And The Competing Symmetries Argument, Arthur D. Dressenwall

Mathematics, Statistics, and Computer Science Honors Projects

We examine the $k=1$ case of a conjecture by Baernstein and Loss pertaining to the operator norm of the $k$-plane transform from $L^p(\R^d)$ space to $L^q(\M)$ space. Previous work on this problem by Carlen and Loss, as well as by Drouot, has used an iterative technique known as the ``competing symmetries argument’’ to prove this conjecture in the $q=2$ and $q=d+1$ cases. We summarize the conjecture and this proof technique, then perform work that strongly suggest that no sufficiently ``nice” transformation exists that can be used to apply the competing symmetries argument to other cases of the conjecture.

Expanding The Library Of Planet Building Materials In Magrathea, Rosalie Chaleunsouck, Tristan Benally

Undergraduate Research Symposium Posters

Exoplanets are often modeled with fully-differentiated layers of iron, silicates, water, and gas. The large pressure and temperature ranges within each layer results in changes of phase and mineral equilibrium. MAGRATHEA is an open-course planet interior structure code with a large library of equations of state for planet building materials. This allows for the user to build detailed planet models and test differing measurements of the equation of state. We extend MAGRATHEA's library to include upper-mantle materials and various phases of iron cores. We show the impact of these materials on the characterization of rocky planet interiors.

Sustainability In Web Development Through Energy Efficiency, Hannah Bebinger

Honors Projects

As global internet usage expands, websites are growing in both size and complexity. Contrary to the common belief that the internet is immaterial and “environmentally friendly”, web pages have significant negative environmental impacts (Frick, 2015). Websites contribute to global greenhouse gas (GHG) emissions and electricity consumption. Considering the current climate crisis, it is crucial that web developers be aware of the impact that their work has on the environment and actively work to improve site energy efficiency. With a lack of regulation and awareness, the environmental impact of websites has remained unchecked despite growing concerns for sustainability. Further research and …

An Investigation Of Water Obstructions And Related Weather Conditions For Nebraska Roadways, Logan Bundy

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Roadway resilience across the 10,000 miles of road and 3,500 bridges in Nebraska is critical to the economic success of production and logistics. In a state where historical flooding scenarios, such as the one in March 2019 that caused $150 million in damage, could potentially be increasing, it has become essential to understand the spatial and temporal distribution of high-frequency water obstruction areas on roadways. Using Nebraska Department of Transportation (NDOT) historical water obstruction data from June 2016 through August 2021, statistical and spatial analyses were conducted to quantify the relationship between water obstructions and their associated meteorological conditions, and …

Geology Of The Kurucaşile - Cide Region, Nw Türkiye, Okan Tüysüz

Bulletin of the Mineral Research and Exploration

The lowest unit of the Cide-Kurucaşile region is the Carboniferous coal-bearing terrestrial sediments. Permian aged terrestrial Çakraz Formation and the Triassic lacustrine Çakrazboz Formation unconformably overlie the Palaeozoic sequence. Dogger-aged Himmetpaşa Formation represents a short-period marine invasion. The transgression started in the Kimmerician has led to the development of a carbonate platform, which has risen and demised after the Berriasian. A second carbonate platform, much more limited than the previous one, developed in the Late Barremian, and then the whole region deepened. The Cenomanian is a period of regional uplift and erosion. The first effective volcanic activity in the region …

Eye-Tracking Using Deep Learning, Sam Trenter

Theses

Eye-tracking can be valuable for researchers in many domains. Most eye-tracking technologies require an extra piece of costly hardware. Several other available eye-tracking solutions are usually not very accurate and require a costly subscription. Our project was oriented at creating a free and open-source alternative that does not require additional equipment. We developed a deep learning-based solution as a prototype for this project. Specifically, we developed a deep learning model to predict a user’s gaze position on the screen. We created our training data set using a commercially available eye-tracker to train the model. Each training sample consists of a …

Bounding Projective Hypersurface Singularities, Benjamin Castor

Arts & Sciences Electronic Theses and Dissertations

We first provide background necessary for understanding monodromy and spectra. We then compare several different methods involving Hodge-theoretic spectra of singularities which produce constraints on the number and type of isolated singularities on a projective hypersurface of fixed degree. In particular, we introduce a method based on the spectrum of the nonisolated singularity at the origin of the affine cone on such a hypersurface, and relate the resulting explicit formula to Varchenko’s bound. We then provide a purely combinatorial interpretation of our theorems and our conjecture.

The Connections Between Innovation, Culture, And Expertise In Water Infrastructure Organizations, Alice Brawley-Chesworth

Dissertations and Theses

Infrastructure organizations are notoriously conservative and resistant to change, even when faced with wicked problems that cannot be solved with the same thinking used in the past. In the water sector, this resistance to change has been linked to an industry culture that is based in a single, engineering-oriented knowledge system. Scholars have suggested that diversification of knowledge systems is necessary for implementation of innovations that will move the sector forward to solve wicked problems.

This research used a qualitative case study approach comparing two water sector organizations in Portland, Oregon. One organization included members who shared an engineering knowledge …

Meas: Exploring Links Between Implementation And Standards Mastery, Noah Silver

Honors Projects

In order to effectively enhance a student’s mathematical understanding and development in the field of mathematics, students need to engage in problem solving. Model eliciting activities, or MEAs, provide students with tasks that promote higher level thinking and the ability to utilize mathematics outside of the classroom; they also align and promote the utilization of the Common Core State Standards and Standards for Mathematical Practice. Research suggests that the language and motivation promoted by MEAs enriches engagement and increases student ability and performance of traditional and real-world mathematics. Use of technology further supports these goals. Through the analysis of checkpoint …

Low-Cost Adsorbent For Disinfection Byproduct Removal From Drinking Water, Savanna Vacek, Suraj Pochampally

Undergraduate Research Symposium Posters

Disinfection byproducts (DBPs) are harmful contaminants that are unintentionally created in disinfected water after chlorination. Activated carbon, often expensive and difficult to acquire in low-income and rural areas, has previously been used to remove DBPs from drinking water. Biochar is made from agricultural waste (i.e. feedstock) and has been identified as a low-cost yet effective adsorbent to remote contaminants from drinking water. This work focuses on the efficacy of biochar and activated carbon to remove DBPs from drinking water for the purpose of treating drinking water after emergency chlorination. This study has the potential to help water distributors and disadvantaged …
