Classical genetic studies have identified many cases of pleiotropy where mutations in individual genes alter many different phenotypes. Quantitative genetic studies of natural genetic variants frequently examine one or a few traits, limiting their potential to identify pleiotropic effects of natural genetic variants. Widely adopted community association panels have been employed by plant genetics communities to study the genetic basis of naturally occurring phenotypic variation in a wide range of traits. High-density genetic marker data—18M markers—from 2 partially overlapping maize association panels comprising 1,014 unique genotypes grown in field trials across at least 7 US states and scored for 162 …

Stillness And Motion On The Coffee Table: Photochemical Motion Pictures In Gilded Age Periodical, Amy E. Borden

School of Film Faculty Publications and Presentations

My research suggests that in addition to local practices, American film historians should continue to be attentive to mass experiences determined not only by location but, in this case, by 19th century periodical reading habits. I focus on the first four years of US public photochemical motion picture exhibition to consider the similarities I found in the use of still photographs to explain and introduce the machines and development processes used to introduce photochemical motion pictures to middle-class reading publics, effectively inviting readers to mentally animate the images themselves in imitatiion of a screening apparatus. I argue that the use …

Unveiling The Mask Of Post-Race Legitimacy: Preserving White Supremacy Through The Use Of Colorblind Racism In Policy Preference, Vanessa Gonzalez

Senior Theses

Recent literature has brought attention to an avoidance of race-talk among Whites that not only attributes social inequalities to non-racial factors, but challenges the existence of racism at all, and reinforces the power of white supremacy in a way that is hard to detect. The paradigm shift from Jim Crow to colorblind racism simply demonstrates a practice of oppression that has been redefined and reshaped, but the foundation of our society that has been built on white supremacy and racial inequality has yet to change. In order to preserve this foundation, colorblind ideology has been used to implement coded language …

Due to the intrusion of magmatic rock, the original coal seam is baked and transformed into natural coke. In this study, samples of natural coke from various areas were collected to study its macroscopic and microscopic characteristics. The industrial analysis, geochemical parameters, …

Nanopore Structure And Surface Roughness In Brittle Tectonically Deformed Coals Explored By Atomic Force Microscopy, Zhang Ningyuan, Yao Suping

Coal Geology & Exploration

The pore structure of coal is the key to coalbed methane (CBM) exploration and exploitation, and coal mining safety. Compared to primary coals, tectonically deformed coals (TDCs) have stronger heterogeneity and are of great importance in coal reservoir study. Here, the pore structure and surface roughness of brittle TDCs were obtained with atomic force microscopy (AFM) and NanoScope Analysis and Gwyddion software. The results show that tectonic deformation generally promotes the pore development in brittle TDCs, but the extent of tectonic impact varies greatly among different brittle TDCs. As a result, two stages in brittle TDCs were identified: weak brittle …

Toward An Environmental History Of The First Great Awakening, David Blakely

History Theses, Dissertations, and Student Creative Activity

The events that came to be known as “The First Great Awakening” began in the wake of Enlightenment ideas that emphasized secular rationalism. Among Christian leaders in the British colonies in North America there was a general perception that passion for religion had grown stale. Itinerant Christian preachers began to travel from town to town and organize large outdoor meetings where they preached forcefully about each individual’s responsibility for their salvation from sin. Many of these revival meetings included spontaneous outbursts of religious fervor from members of the crowd that took the form of shouting, weeping, speaking in tongues, dancing, …
