Presidential Leadership in the Space Age

Mankind’s quest to reach the moon consisted of many people in leadership positions. In the US, however, many of the decisions behind the space race, especially funding for it, were made by four men: Dwight D. Eisenhower, John F. Kennedy, Lyndon Baines Johnson, and Richard Nixon. While some presidents (namely Kennedy) receive more credit than others for their work on bringing man to the moon, each of them passed influential policy that was vital in the development of Apollo: Eisenhower founded NASA and began research on the Saturn V, Kennedy gave vision and urgency to the program, Johnson gave massive funding to it, and Nixon oversaw the program and decided what would come next

To Bigotry No Sanction, To Persecution No Assistance: Jews in the American Revolutionary Period

While Jews were a small minority in the American colonies, they nonetheless participated in the American Revolution on both sides. This paper aims to evaluate the role of Jewish people in the conflict, contextualizing the experiences of this small minority within the larger narrative of the American Revolution and establishing their importance in the development of religious freedom in the United States. Through the examination of these topics, this paper aims to explore the Revolutionary period from the perspective of the Jewish-American, discussing their often-overlooked experiences in this watershed period within U.S. history

Beneath the Tower: The Story of a Campus Icon

A history of Glatfelter Hall, one of the most iconic buildings on the Gettysburg College campus. This paper also aims to compare Glatfelter with a similarly iconic building on the campus of UVA, the Rotunda. Finally, it proposes a series of interpretive markers about the history of Glatfelter Hall both in terms of content and placement

Dr. Seuss and Uncle Sam

This is an examination of the WWII era political cartoons of Theodor Geisel (aka Dr. Seuss), which covered a variety of topics ranging from isolationism to anti-Axis propaganda to racism and bigotry at home. The project further investigates the attitudes of German-Americans towards Hitler, using Geisel\u27s very vocal hatred of the Nazi leader to compare his sentiments with many of his contemporary peers

Radical and ion molecule mechanisms in the polymerization of hydrocarbons and chlorosilanes in RF plasmas at low pressures ( 1.0 torr)

The ion-molecule and the radical-molecule mechanisms are responsible for the dissociation of hydrocarbons, and chlorosilane monomers and the formation of polymerized species, respectively, in the plasma state of a RF discharge. In the plasma, of a mixture of monomer with Ar, the rate determining step for both dissociation and polymerization is governed by an ion-molecular type interaction. Additions of H2 or NH3 to the monomer Ar(+) mixture transforms the rate determining step from an ion-molecular interaction to a radical-molecule type interaction for both monomer dissociation and polymerization processes

Homogeneous reactions of hydrocarbons, silane, and chlorosilanes in radiofrequency plasmas at low pressures

The ion-molecule and radical-molecule mechanisms are responsible for the dissociation of hydrocarbon, silane, and chlorosilane monomers and the formation of polymerized species, respectively, in an RF plasma discharge. In a plasma containing a mixture of monomer and argon the rate-determining step for both dissociation and polymerization is governed by an ion-molecule type of interaction. Adding hydrogen or ammonia to the monomer-argon mixture transforms the rate-determining step from an ion-molecule interaction to a radical-molecule interaction for both monomer dissociation and polymerization

Correlations between plasma variables and the deposition process of Si films from chlorosilanes in low pressure RF plasma of argon and hydrogen

The dissociation of chlorosilanes to silicon and its deposition on a solid substrate in a RF plasma of mixtures of argon and hydrogen were investigated as a function of the macrovariables of the plasma. The dissociation mechanism of chlorosilanes and HCl as well as the formation of Si in the plasma state were studied by sampling the plasma with a quadrupole mass spectrometer. Macrovariables such as pressure, net RF power input and locations in the plasma reactor strongly influence the kinetics of dissociation. The deposition process of microcrystalline silicon films and its chlorine contamination were correlated to the dissociation mechanism of chlorosilanes and HCl

Monuments of Legitimacy: 17th Century Tokugawa-Sponsored Architecture as Political Objects

This work aims to synthesize art history, historical memory, and Tokugawa-era Japanese politics with an art history approach and cultural analysis. It takes a more complete look at the politics of Tokugawa Ieyasu’s death and the significance of memorial and religious architecture as political works. It examines the utilization of architecture as a way to elevate and legitimize the Tokugawa, demonstrating that policy was not the only way for the Tokugawa to solidify their legacy and suggesting that key figures like Ieyasu were more important to the religious and political structures of Tokugawa Japan in death than they were in life. This paper begins by discussing the immediate political effects of Ieyasu’s death and the establishment of the Nikko Toshogu before discussing the physical aspects of the shrine and comparing it with the Ise Shrine to establish the relationship between the shogun and the Emperor. Finally, it examines the mausoleum of Sūgen-in, Tokugawa Iemitsu’s mother, in order to contextualize the shift of the architectural style of female mausoleums to emulate those of their male counterparts, showing a growing inclusivity towards women in establishing the legacy of the Tokugawa during the early Edo Period

Proximity Drawings of High-Degree Trees

A drawing of a given (abstract) tree that is a minimum spanning tree of the vertex set is considered aesthetically pleasing. However, such a drawing can only exist if the tree has maximum degree at most 6. What can be said for trees of higher degree? We approach this question by supposing that a partition or covering of the tree by subtrees of bounded degree is given. Then we show that if the partition or covering satisfies some natural properties, then there is a drawing of the entire tree such that each of the given subtrees is drawn as a minimum spanning tree of its vertex set
