Paleocene Depositional History Of The Cretaceous-Paleogene Impact Basin, Yucatan Peninsula, Mexico, Katherine E. O'Malley Dec 2020

Paleocene Depositional History Of The Cretaceous-Paleogene Impact Basin, Yucatan Peninsula, Mexico, Katherine E. O'Malley

Geosciences

In the spring of 2016, the International Ocean Discovery Program set out on Expedition 364 to recover core from the peak ring of Chicxulub Impact Crater at Site M0077. In total, 829 m of core was collected spanning granite to Paleogene sedimentary rocks. From this core, we have a well-preserved record of the Paleocene, which represents ~10 million years post impact in just under 10 m of sedimentary rock record. This has presented an incredible research opportunity, as we have gained invaluable information on how the environment responded and recovered from the global catastrophe that was the Chicxulub Impact. The …

Geochemical, Spatial, And Temporal Relationships Of The Intrusives And Meta-Intrusives Of The Pogo Deposit, Eastern Interior, Ak, William D. Thompson Dec 2020

Geochemical, Spatial, And Temporal Relationships Of The Intrusives And Meta-Intrusives Of The Pogo Deposit, Eastern Interior, Ak, William D. Thompson

Geosciences

The Pogo deposit is an intrusion-related gold deposit (IRGD) located approximately 90 km southeast of Fairbanks, Alaska. It consists mainly of shallowly NW dipping quartz veins hosted in amphibolite facies paragneiss and predominately granite orthogneiss bodies. To date the deposit has produced over 4 million ounces of gold. U-Pb zircon dating of the orthogneisses shows they have Devonian-Mississippian protolith ages. Dates from the metamorphic zircons, established by microprobe Th data and cathodoluminescence studies, constrain a mid-Cretaceous metamorphic event to ~116 Ma. Recrystallization of kyanite to sillimanite and zircon recrystallization indicates this was a large fluid flux event that predated mineralization …

Servant Leadership In Education-Based Nonprofits, Charline Rivera '21 Dec 2020

Servant Leadership In Education-Based Nonprofits, Charline Rivera '21

Independent Study

The presence of Servant Leadership within our communities is undeniable; organizations such as The Container Store, Southwest Airlines, and Starbucks dominate our everyday lives, providing services that serve various communities within their own unique ways. However, what makes organizations based on Servant Leadership distinct and successful lies in both the impact and those running the organizations. Every employee, manager, or volunteer must maintain a certain connection to values and self-awareness, and be flexible and prepared for change in any work they do. This being said, internal motivations and desires always come second to the needs of the community being served, …

Mortgage Discrimination And District Manipulation: Deterrents To Minority Mobility, Megan M. Rice Dec 2020

Mortgage Discrimination And District Manipulation: Deterrents To Minority Mobility, Megan M. Rice

Honors Theses

This paper explores the relationship between gerrymandering and home loan discrimination. Gerrymandering, the process of manipulating district plans for political gain, and discrimination in mortgage lending are both illegal; and yet, they still occur in today’s society. By using individual loan application data from the HMDA’s website, a series of regressions will be run using applicant characteristics to measure loan discrimination at the state level. Once a state level model has been constructed, a measure of gerrymandering called the Efficiency Gap will be added into the regression in order to explore the relationship between home loan discrimination and gerrymandering. Regression …

Thermally Stable Fluorogenic Zn(Ii) Sensor Based On A Bis(Benzimidazole)Pyridine-Linked Phenyl-Silsesquioxane Polymer, Chamika U. Lenora, Nai-Hsuan Hu, Joseph C. Furgal

Chemistry Faculty Publications

A 2,6-bis(2-benzimidazolyl) pyridine-linked silsesquioxane-based semi-branched polymer was synthesized, and its photophysical and metal-sensing properties have been investigated. The polymer is thermally stable up to 285 °C and emits blue in both solid and solution state. The emission of the polymer is sensitive to pH and is gradually decreased and quenched upon protonation of the linkers. The initial emission color is recoverable upon deprotonation with triethylamine. The polymer also shows unique spectroscopic properties in both absorption and emission upon long-term UV irradiation, with red-shifted absorption and emission not present in a simple blended system of phenylsilsesquioxane and linker, suggesting that a …

When The Great Equalizer Shuts Down: Schools, Peers, And Parents In Pandemic Time, Francesco Agostinelli, Matthias Doepke, Giuseppe Sorrenti, Fabrizio Zilibotti Dec 2020

When The Great Equalizer Shuts Down: Schools, Peers, And Parents In Pandemic Time, Francesco Agostinelli, Matthias Doepke, Giuseppe Sorrenti, Fabrizio Zilibotti

Cowles Foundation Discussion Papers

What are the effects of school closures during the Covid-19 pandemic on children’s education? Online education is an imperfect substitute for in-person learning, particularly for children from low-income families. Peer effects also change: schools allow children from different socio-economic backgrounds to mix together, and this effect is lost when schools are closed. Another factor is the response of parents, some of whom compensate for the changed environment through their own efforts, while others are unable to do so. We examine the interaction of these factors with the aid of a structural model of skill formation. We find that school closures …

Marine Science

Hydrogen chloride (HCl) is the most abundant (more than 95 %) among inorganic chlorine compounds Cly in the upper stratosphere. The HCl molecule is observed to obtain long-term quantitative estimations of the total budget of the stratospheric chlorine compounds. In this study, we provided HCl vertical profiles at altitudes of 16 100 km using the Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) from space. The HCl vertical profile from the upper troposphere to the lower thermosphere is reported for the first time from SMILES observations; the data quality is quantified by comparison with other measurements and via theoretical error analysis. We used …

Publications and Research

Many studies examine the correlation between the use of resources such as water, energy and land, and the production of food. These nexus studies focus predominantly on large scale systems, often considering the social dimensions only in terms of access to resources and participation in the decision- making process, rather than individual attitudes and behaviours with respect to resource use. Such a concept of the nexus is relevant to urban agriculture (UA), but it requires customisation to the particular characteristics of growing food in cities, which is practiced mainly at a small scale and produces not only food but also …

Effect Of Airfoil-Preserved Undulations On Wing Performance And Wingtip Vortex, Faith A. Loughnane Dec 2020

Effect Of Airfoil-Preserved Undulations On Wing Performance And Wingtip Vortex, Faith A. Loughnane

Honors Theses

The effect of undulation placement (leading edge, trailing edge, leading and trailing edge) on the wing performance and the wingtip vortex was investigated. Experiments were performed at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) on undulated wings where the NACA 0012 airfoil cross-section is preserved along the wingspan. Sensitivity studies were done on the undulation wavelength along the span (λ/c 0.31, 0.21 and 0.15) and undulation placement (leading edge, trailing edge, and both leading and trailing edge). The leading edge undulations delayed stall until higher angles of attack, however, the maximum aerodynamic efficiency was reduced. The trailing edge …
