The overall goal of this research project was to assess the feasibility of investigating the effects of microgravity on mineralization systems in unit gravity environments. If possible to perform these studies in unit gravity earth environments, such as earth, such systems can offer markedly less costly and more concerted research efforts to study these vitally important systems. Expected outcomes from easily accessible test environments and more tractable studies include the development of more advanced and adaptive material systems, including biological systems, particularly as humans ponder human exploration in deep space. The specific focus of the research was the design and …

Historically, colonizers, immigrants, and enslaved Africans served as carriers of Islamic culture to Puerto Rico, and today, that Islamic element is often unassumingly intertwined with the Puerto Rican culture. Using Bourdieu's concept of habitus as the framework, this dissertation engages customs and mannerisms of Puerto Ricans to reveal the imprint and legacy of Muslim Spain and the Islamic heritage of West Africa in Puerto Rico. It makes a study of the Spanish language to include vocabulary, proverbs, songs, and games that carry vestiges of Arabic language and culture. Most importantly, it also addresses an inherited religious and cultural tradition rooted …

This dissertation theorizes Bad Faith Rhetorics, or, rhetorical gestures that work to derail, block, or otherwise stymy knowledge-building efforts. This work explores the ways that interventions against existing social hierarchies (i.e., feminist and antiracist interventions) build knowledge (that is, are epistemologically active), and the ways that bad faith rhetorics derail such interventions. This dissertation demonstrates how bad faith rhetorics function to defend the status quo, with its social stratification by race, gender, class, and other intersectional axes of identity. Bad faith argumentative maneuvers are abundant in online environments. Consequently, this dissertation offers two case studies of the comment sections of …

Situated within seminal debates on the questions of liberation and justice viewed from the postcolonial context, this dissertation evaluates freedom narratives from both sides of the colonial divide during the period of high imperialism. Creating a transnational grouping of three diverse historical figures, E. M. Forster, M. K. Gandhi, and James Joyce, I argue for similarities in these writers’ narrative construction of “freedom” against colonial modernity. I argue that despite these writers’ widely disparate historical and cultural determinations, which uniquely particularize each of their freedom formulas as well as freedom “ideals” – the ideal of culture for Forster, renunciation for …

According to the World Health Organization, cancer is one of the leading causes of death around the world. Although early diagnostics using biomarkers and improved treatments with targeted therapy have reduced the rate of cancer related mortalities, there remain many unknowns regarding the contributions of the tumor microenvironment to cancer progression and therapeutic resistance. The tumor microenvironment plays a significant role by manipulating the progression of cancer cells through biochemical and biophysical signals from the surrounding stromal cells along with the extracellular matrix. As such, there is a critical need to understand how the tumor microenvironment influences the molecular mechanisms …

Personal histories are deeply rooted into my way of existence, far before my brain became ready to challenge such notions. While Americans have been witnesses to the splintering effects of colonialism and patriarchy on socialization, I ask two questions: (1) Where to stand within a society that promotes the marginalization of both women and brown bodies? And (2) how to combat these harsh realities and protect those most affected? Being both Black and woman, I decided to embark upon a quest of self-actualization in this document. “Ain’t She Sweet: A Critical Choreographic Study of Identity & Intersectionality,” tracks the creative …

The aim of this research study is to develop a passive architectural design morphology, tuned to the Sonoran Desert, which redefines Desert Modernism and integrates: (a) mitigation of heat transfer through the exterior envelope, and (b) use of daylight to inform appropriate architectural massing. The research investigation was delimited to mid-nineteenth century European modernist examples, and ends with mid-twentieth century modern architecture in the southwestern United States as viewed through the lens of environmental design. The specific focus was on Desert Modernism, a quasi-architectural movement, which purportedly had its beginnings in 1923 with the Coachella Valley, Popinoe Desert Cabin. A …

The objective of this study was to evaluate possible bioremediation strategy for aerobic aquifers by combining ZVI chemical reduction and microbial reductive dechlorination for TCE and ClO4-. To achieve this objective, continuous flow-through soil columns were used to test the hypothesis that bioaugmentation with dechlorinating enrichment cultures downstream of the ZVI injection can lead to complete reduction of TCE and ClO4- in aerobic aquifers. We obtained soil and groundwater from a Superfund site in Arizona. The experiments consisted of 205 cm3 columns packed with soil and ZVI, which fed 1025 cm3 columns packed with soil, biostimulated with fermentable substrates and …

Wearable assistive devices have been greatly improved thanks to advancements made in soft robotics, even creation soft extra arms for paralyzed patients. Grasping remains an active area of research of soft extra limbs. Soft robotics allow the creation of grippers that due to their inherit compliance making them lightweight, safer for human interactions, more robust in unknown environments and simpler to control than their rigid counterparts. A current problem in soft robotics is the lack of seamless integration of soft grippers into wearable devices, which is in part due to the use of elastomeric materials used for the creation of …

Despite the fact that machine learning supports the development of computer vision applications by shortening the development cycle, finding a general learning algorithm that solves a wide range of applications is still bounded by the ”no free lunch theorem”. The search for the right algorithm to solve a specific problem is driven by the problem itself, the data availability and many other requirements. Automated visual inspection (AVI) systems represent a major part of these challenging computer vision applications. They are gaining growing interest in the manufacturing industry to detect defective products and keep these from reaching customers. The process of …

Ideas from coding theory are employed to theoretically demonstrate the engineering of mutation-tolerant genes, genes that can sustain up to some arbitrarily chosen number of mutations and still express the originally intended protein. Attention is restricted to tolerating substitution mutations. Future advances in genomic engineering will make possible the ability to synthesize entire genomes from scratch. This presents an opportunity to embed desirable capabilities like mutation-tolerance, which will be useful in preventing cell deaths in organisms intended for research or industrial applications in highly mutagenic environments. In the extreme case, mutation-tolerant genes (mutols) can make organisms resistant to retroviral infections. …

The study of soft magnetic materials has been growing in popularity in recent years. Driving this interest are new applications for traditional electrical power-management components, such as inductors and transformers, which must be scaled down to the micro and nano scale while the frequencies of operation have been scaling up to the gigahertz range and beyond. The exceptional magnetic properties of the materials make them highly effective in these small-component applications, but the ability of these materials to provide highly-effective shielding has not been so thoroughly considered. Most shielding is done with traditional metals, such as aluminum, because of the …

Cancer is a serious health concern. Current treatments are limited due to certain subpopulations of cancer cells being resistant to chemotherapy and radiation. These subpopulations have been qualitatively identified but much work remains to quantify the abnormalities they exhibit such as irregular nuclear shape. This dissertation seeks to determine physical science methods which can identify and quantify the biological characteristics of cancer and non-cancer cells. For the first project, the deoxyribonucleic acid (DNA) and chromatin of cancer and non-cancer esophageal cells were quantified using spectrophotometry and atomic force microscopy. Then the cellular nucleus shape, chromocenters, nucleoli, and nuclear speckles were …

Officials employed in the criminal justice system have a duty to serve, protect, and uphold the law. Nevertheless, previous research has found problematic drinking and illegal substance use exists among criminal justice system employees. Criminal justice employees may be more likely to use substances due to strains or due to increased access to drug. On the other hand, self-selection and screening processes may result in a pool of employees who fewer substances than the general population. Using waves 1 through 17 of the National Longitudinal Survey of Youth 1997, the current research examines substance use patterns of criminal justice system …

This dissertation will cover two topics. For the first, let $K$ be a number field. A $K$-derived polynomial $f(x) \in K[x]$ is a polynomial that factors into linear factors over $K$, as do all of its derivatives. Such a polynomial is said to be {\it proper} if its roots are distinct. An unresolved question in the literature is whether or not there exists a proper $\Q$-derived polynomial of degree 4. Some examples are known of proper $K$-derived quartics for a quadratic number field $K$, although other than $\Q(\sqrt{3})$, these fields have quite large discriminant. (The second known field is $\Q(\sqrt{3441})$.) …
