The Relationship Between ACE2 and the ABO Blood Groups in SARS-CoV-2 Infection Rates
No full text37 leaves : illustrations.Includes bibliographical references (leaves 33-37).The COVID-19 pandemic is one of the most brutal pandemics mankind has had to endure. The novel coronavirus has taken the world by storm, with millions of deaths in just a year. Further research has indicated that the coronavirus responsible, SARS-CoV-2, may attribute to outlasting health defects, such as cardiovascular or pulmonary problems. The survival rate for people infected with this virus is grim, depending on where you are in the world, if there are any comorbidities present, or if variants are present in the area. Emerging literature on ABO blood groups suggest that there may be a correlation between a certain blood group and SARS-CoV-2 susceptibility. The objective of this study was to investigate the rate of infection according to ABO blood groups. In this study, data was compiled and analyzed in a meta-analysis to calculate odds-ratios. Our results show that blood group A individuals may be more susceptible to SARS-COV-2 infection while blood group O individuals may have a protective effect against the virus. This study may provide further insight into how blood groups may affect SARS-CoV-2 susceptibility.I.

A new radio census of neutron star X-ray binaries
Full text link24 pages with color illustrations.We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day sensitivities. These sources include 13 weakly magnetized (B < 1010 G) and 23 strongly magnetized (B ≥ 1010 G) NSs. 16 of the latter category reside in high-mass X-ray binaries, of which only two systems were radio-detected previously. We detect four weakly and nine strongly magnetized NSs; the latter are systematically radio fainter than the former and do not exceed LR ≈ 3 × 1028 erg s−1. In turn, we confirm the earlier finding that the weakly magnetized NSs are typically radio fainter than accreting stellar-mass black holes. While an unambiguous identification of the origin of radio emission in high-mass X-ray binaries is challenging, we find that in all but two detected sources (Vela X-1 and 4U 1700-37) the radio emission appears more likely attributable to a jet than the donor star wind. The strongly magnetized NS sample does not reveal a global correlation between X-ray and radio luminosity, which may be a result of sensitivity limits. Furthermore, we discuss the effect of NS spin and magnetic field on radio luminosity and jet power in our sample. No current model can account for all observed properties, necessitating the development and refinement of NS jet models to include magnetic field strengths up to 1013 G. Finally, we discuss jet quenching in soft states of NS low-mass X-ray binaries, the radio non-detections of all observed very-faint X-ray binaries in our sample, and future radio campaigns of accreting NSs
Ancient Coins in the Hendricks Bequest: Identification and Worth
No full text193 pages; illustrations193 leaves : illustrations.Includes bibliographical references (leaves 188-193).The Hendricks Bequest totals 314 ancient Greek and Roman coins. I have fully identified, cataloged, and photographed these coins. A discussion the theoretical concepts of value within an academic collection, the interdisciplinary uses of numismatics, and the Hendricks Bequest’s future conclude this thesis.Introduction -- Numismatic History of the Wheaton College Permanent Collection -- History of the Hendricks Bequest -- Introduction to Project -- Identification of Ancient Coins -- Dating of Ancient Coins -- Sources and Citations --Tables -- Data Presented -- Notation in the Coin Tables -- Numismatic Terms of Note -- Greek Coins -- Roman Coins -- From Augustus to Diocletian Pre-Reform -- From Diocletian (Post-Reform) to Arcadius -- Misc.

Mechanochemical Synthesis of Thiolactams with Lawesson's Reagent
No full text32 pages, illustrationsThiolactams have proved to be an essential class of compounds in medicine, agriculture,
and chemical synthesis. These compounds can be reliably synthesized with 2,4-bis(4- methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-dithione a thionation reagent that has widely become known as Lawesson's reagent (LR). In this study mechanochemistry, a new subfield of solid-state chemical synthesis which has proven useful because of its environmentally friendly nature and highly optimizable reaction conditions is used to develop the first known mechanochemical synthesis with Lawesson's reagent to produce thiolactams ring sizes 5 through 8
Naming matters : 'Anglo-Saxon' from Hengist and Horsa to Charlotte the WASP Princess.
No full text45 leaves.Includes bibliographical references (leaves 43-45).In 2019, medievalist and scholar, Mary Rambaran-Olm, delivered a very public resignation from her position as second vice president of The International Society of Anglo-Saxonist due to the society’s refusal to change its name. This triggered a larger conversation about the use of the term “Anglo-Saxon.” Not only has “Anglo-Saxon” been used incorrectly, but recently it has been adopted by white supremacists that have incited violence and racism behind their use of the term. This thesis examines the origins of “Anglo-Saxon” up until the 20th century through the term W.A.S.P. (White, Anglo-Saxon, Protestant) as well as the origins of Anglo-Saxon studies within the English Curriculum. I also discuss the controversy surrounding the name change in 2019 which leads me to discussing why naming matters with a term like “Anglo-Saxon,” specifically in a field that has a history of being alienating towards Black and POC scholars
Functional morphology of the Ocean Sunfish (Mola mola) Pharyngeal Jaw
No full text39 pages; illustrations39 leaves : illustrations.Includes bibliographical references (leaves 35-39).This study looked at the functional morphology of the ocean sunfish (Mola mola) pharyngeal jaw by looking at the general morphology, behavior under force, and the gelatinous prey retention of the pharyngeal jaws and teeth. This study demonstrates a novel use of pharyngeal teeth in fish, similar to structures found throughout the vertebrates that prevent the loss of ingested food and newly acquired prey items. We also discovered a functionally unique muscle to control the eversion of these teeth and other morphological characteristics (high safety factor, tooth replacement) that highlight the critical role of these teeth to the mola. Lastly, this study demonstrated that these teeth are likely only useful in adult fish, which follows the known ontogenetic diet shift
