Facies Architecture And Provenance Of The Highly Progradational, Fluvial Dominated Deltaic Depositional System Of The Cretaceous Nanushuk Formation On The North Slope Of Alaska, Sarah N. Naone Dec 2022

Facies Architecture And Provenance Of The Highly Progradational, Fluvial Dominated Deltaic Depositional System Of The Cretaceous Nanushuk Formation On The North Slope Of Alaska, Sarah N. Naone

Theses and Dissertations

The Cretaceous Nanushuk Formation of northern Alaska records extremely rapid shoreline progradation across the Colville Basin during the Albian-Cenomanian epochs. Additionally, it records a period of tectonic realignment in the region, as the main sediment source began to transition from the Chukotkan orogeny to the west to a more local sediment source of the proximal Brooks Range to the south. Through detailed outcrop characterization and 3-D modeling of three exposed outcrops along the axial trend of the Colville Basin on the North Slope and the Upper section of the Nanushuk, this study clarifies the relative timing of the early Brookian …

Teachers’ Perceptions Of Students’ Writing Skills: An Examination Of The Agreement Between Teachers’ Judgments And Curriculum-Based Measurement In Written Expression, Emily Ann Watts

Theses - ALL

Nearly 75% of students in the United States of America are not meeting grade-level standards in the area of writing (NCES, 2012; Persky et al., 2003), despite this skill impacting students’ performances in other academic areas (Ray et al., 2016), and limiting students’ access to higher education (Addison & McGee, 2010), and opportunities for jobs in the adult workforce (National Commission on Writing, 2005). Because difficulties with early writing skills are associated with later writing skills deficits (Juel, 1988), it is crucial that educators accurately identify students in need of additional support in order to provide them with appropriate instruction. …

Standardization Of A Latent Blood Visualizer Based Upon Dna Degradation, Kailey M. Van 'T Hoff Dec 2022

Standardization Of A Latent Blood Visualizer Based Upon Dna Degradation, Kailey M. Van 'T Hoff

Honors Projects

Latent blood visualizers have been used in forensic science since 1937 beginning with Luminol. These visualizers through different types of reactions react with trace amounts of blood that cannot be seen with the naked human eye. These different reactions produce color that can then be seen by examiners. The four types of latent blood visualizers that were compared is luminol, leuco crystal violet, fluorescein, and bluestar. Luminol and bluestar use chemiluminescence, fluorescein uses florescent, and leuco crystal violet uses oxidation to react with iron in hemoglobin. At crime scenes when blood is detected which includes with the blood visualizers the …

Methods For Engineers To Understand, Predict, And Influence The Social Impacts Of Engineered Products, Phillip Douglas Stevenson Dec 2022

Methods For Engineers To Understand, Predict, And Influence The Social Impacts Of Engineered Products, Phillip Douglas Stevenson

Theses and Dissertations

Engineered products can impact the day-to-day life of their users and other stakeholders. These impacts are often referred to as the product's social impacts. Products have been known to impact the people who use them, design them, manufacture them, distribute them, and the communities where they exist. Currently, there are few methods that can help an engineer identify, quantify, predict, or improve a product's social impact. Some companies and organizations have tried to identify their impacts and, for example, set goals for achieving more sustainable business practices. However, engineers, in large part, do not have methods that can help improve …

Evaluation Of Yttrium Stabilized Zirconium Thin Films With Secondary Ion Mass Spectrometry, Jeff Serfass Dec 2022

Evaluation Of Yttrium Stabilized Zirconium Thin Films With Secondary Ion Mass Spectrometry, Jeff Serfass

Seton Hall University Dissertations and Theses (ETDs)

Fuel Cells using solid oxides for the electrolyte material, or Solid Oxide Fuel Cells (SOFCs), can operate at high temperatures and have many benefits when compared to other electrolyte material-based fuel cells. SOFCs can, however still have problems when operating at these high temperatures. (~1,000 degrees Celsius) At high temperatures, the SOFC electrolyte resistivity goes up making the ionic conductivity decrease and therefore a loss of performance. The inclusion of low level Yttria to Zirconium Oxide (the electrolyte material) has been known to help reduce the resistivity at high operating temperatures. In this study, a series of Yttria stabilized Zirconium …

Toward A More Humane Public Policy: How The Humanities Can, And Should, Inform The Creation And Analysis Of Public Policy, Eric Celler Dec 2022

Toward A More Humane Public Policy: How The Humanities Can, And Should, Inform The Creation And Analysis Of Public Policy, Eric Celler

Master of Arts in Professional Writing Capstones

This capstone investigates how the methodologies of the humanities can inform the creation and analysis of public policy. Since the mid-twentieth century, public policy has increasingly turned away from humanistic questions and toward technical questions. The result has been a public policy regime that focuses too much on manipulable variables and not on the humans that the policies are impacting. By applying humanistic methodologies to public policy, we are more likely to appreciate the inarticulable elements of human social organization and therefore devise public policy that is less harmful and more humble.

Screening Anti-Pd-L2 Peptides As Antitumor Ligands Using Phage Display, Chien Tran Phuoc Dec 2022

Screening Anti-Pd-L2 Peptides As Antitumor Ligands Using Phage Display, Chien Tran Phuoc

Honors Projects

Cancer still remains one of the top leading causes of death in America. Recently, programmed cell death protein 1 (PD-1) blockades have been demonstrated to be highly effective against various types of cancer. By blocking PD-1 from binding with their ligands (PD-L1 and PD-L2), the “off” signal to the immune system is inhibited, hence reinvigorating the immune cells to kill tumor cells. To date, despite PD-L1 and PD-L2 both interacting with PD-1, research efforts have only been focused on developing anti-PD-L1 inhibitors. Therefore, the work of this honor project has focused on finding anti-PD-L2 peptides by phage display, with the …

Real-Time Hybrid Testing Of A Floating Offshore Wind Turbine Using A Surrogate-Based Aerodynamic Emulator, Edward Ransley, Scott Brown, Emma Edwards, Tom Tosdevin, Kieran Monk, Alastair Reynolds, Deborah Greaves, Martyn Hann Dec 2022

Real-Time Hybrid Testing Of A Floating Offshore Wind Turbine Using A Surrogate-Based Aerodynamic Emulator, Edward Ransley, Scott Brown, Emma Edwards, Tom Tosdevin, Kieran Monk, Alastair Reynolds, Deborah Greaves, Martyn Hann

School of Engineering, Computing and Mathematics

Abstract Physical modelling of floating offshore wind turbines (FOWTs) is challenging due to the complexities associated with simultaneous application of two different scaling laws, governing the hydrodynamic and aerodynamic loading on the structure. To avoid these issues, this paper presents a real-time hybrid testing strategy in which a feedback-loop, consisting of an on-board fan, and control algorithm, is utilised to emulate the aerodynamic forces acting on the FOWT system. Here, we apply this strategy to a 70th-scale IEA Wind 15MW reference wind turbine mounted on a version of the VolturnUS-S platform. Unlike other similar methods, which directly simulate the aerodynamic …

A Brief Review Of Dns, Root Servers, Vulnerabilities And Decentralization, Mallory Runyan

Cybersecurity Undergraduate Research Showcase

Since the 1980’s and creation of the World Wide Web, Internet utilization is a common and arguably, necessary, part of daily life. The internet is young and still relatively new, but as of 2016, 3.4 billion people were online, and that number has since grown [1]. This is a significant number, but as such a common part of daily life, how elements of the internet or its infrastructure work is complex. The world would very likely be thrown into dark ages if DNS or any other significant aspect of the internet's infrastructure were to succumb to an attack. The Colonial …

Winter Territoriality Of The American Redstart In Oil Palm Plantations, Samuel L. Oliveira, David J. Flaspohler, Jared D. Wolfe Dec 2022

Winter Territoriality Of The American Redstart In Oil Palm Plantations, Samuel L. Oliveira, David J. Flaspohler, Jared D. Wolfe

Michigan Tech Publications, Part 1

Aspects of territorial behavior of Nearctic-neotropical migratory birds during the nonbreeding period are poorly studied. Information about territoriality, site persistence, between-year site fidelity, and territory sizes are not available for most birds, especially in tropical agroecosystems. Given the rapid expansion of oil palm in the neotropics, determining how oil palm affects the territorial behaviors of overwintering migratory birds is an important line of inquiry with conservation implications. The American Redstart (Setophaga ruticilla) is considered a model species for the study of population dynamics in the neotropics; however, territory size for American Redstart has only been assessed in native habitats. In …

Resilience Monitoring For Multi-Filter All-Source Navigation Framework With Assurance, Jonathon S. Gipson, Robert C. Leishman Dec 2022

Resilience Monitoring For Multi-Filter All-Source Navigation Framework With Assurance, Jonathon S. Gipson, Robert C. Leishman

Faculty Publications

The Autonomous and Resilient Management of All-source Sensors (ARMAS) framework monitors residual-space test statistics across unique sensor-exclusion banks of filters (known as subfilters) to provide a resilient, fault-resistant all-source navigation architecture with assurance. A critical assumption of this architecture, demonstrated in this paper, is fully overlapping state observability across all subfilters. All-source sensors, particularly those that only provide partial state information (altimeters, TDoA, AOB, etc.), do not intrinsically meet this requirement. This paper presents a novel method to monitor real-time overlapping position state observability and introduces an observability bank within the ARMAS framework, known as stable observability monitoring (SOM). SOM …

Diversifying And Perennializing Plants In Agroecosystems Alters Retention Of New C And N From Crop Residues, Marshall D. Mcdaniel, Jeffrey A. Bird, Jennifer Pett-Ridge, Erika Marin-Spiotta, Tom M. Schmidt, A. Stuart Grandy

Faculty Publications

Managing soils to retain new plant inputs is key to moving toward a sustainable and regenerative agriculture. Management practices, like diversifying and perennializing agroecosystems, may affect the decomposer organisms that regulate how new residue is converted to persistent soil organic matter. Here we tested whether 12 years of diversifying/perennializing plants in agroecosystems through extended rotations or grassland restoration would decrease losses of new plant residue inputs and, thus, increase retention of carbon (C) and nitrogen (N) in soil. We tracked dual-labeled (13C and 15N), isotopically enriched wheat (Triticum aestivum) residue in situ for 2 years as it decomposed in three …

Actively Guided Cansats For Assisting Localization And Mapping In Unstructured And Unknown Environments, Cary Chun, M. Hassan Tanveer Dec 2022

Actively Guided Cansats For Assisting Localization And Mapping In Unstructured And Unknown Environments, Cary Chun, M. Hassan Tanveer

Symposium of Student Scholars

When navigating in unknown and unstructured environments, Unmanned Arial Vehicles (UAVs) can struggle when attempting to preform Simultaneous Localization and Mapping (SLAM) operations. Particularly challenging circumstance arise when an UAV may need to land or otherwise navigate through treacherous environments. As the primary UAV may be too large and unwieldly to safely investigate in these types of situations, this research effort proposes the use of actively guided CanSats for assisting in localization and mapping of unstructured environments. A complex UAV could carry multiple of these SLAM capable CanSats, and when additional mapping and localization capabilities where required, the CanSat would …

Hydrogen Bonding In Small Model Peptides; The Dft And Mp2 Study, Gracie Smith, Martina Kaledin Dec 2022

Hydrogen Bonding In Small Model Peptides; The Dft And Mp2 Study, Gracie Smith, Martina Kaledin

Symposium of Student Scholars

Formamide is a small model compound for the study of the peptide bond. The peptide bond links amino acids together, specifies rigidity to the protein backbone, and includes the essential docking sites for hydrogen-bond-mediated protein folding and protein aggregation, namely, the C=O acceptor and the N-H donor parts. Therefore, the infrared C=O (amide-I) and N-H (amide-A) vibrations provide sensitive and widely used probes into the structure of peptides. This computational chemistry work, we study hydrogen bonds in formamide dimer isomers. We evaluate the accuracy of the density functional theory (DFT) and many-body perturbation theory to the 2nd order (MP2) …

Investigating The Electrochemical Behavior Of Dihydropyrrolopyroles For Use As Anodically Coloring Electrochromes, Perry Skiouris, Ally Kisiel, Valentino Sorto, Julia Mauro, Graham Collier

Symposium of Student Scholars

Electrochromic materials have found widespread use in consumer electronics, energy saving windows, and military applications. They contain unique electronic properties allowing them to undergo a color change in a redox reaction. One classification of these molecules is known as anodically coloring electrochromes (ACEs). When in solution, these compounds are transmissive in the neutral (ground) state and absorb visible light upon oxidation, by the formation of a radical cation, thus making them colored. The focus of this study is the electronic transitions of this radical cation and how chemical modifications to the structures produce a variable color profile. To design prospective …
