Potential Impact Of Contour Bunds On Diclofenac Removal For Stormwater Control In Rangeland Applications, Braden Alan Whitehead Sep 2021

Potential Impact Of Contour Bunds On Diclofenac Removal For Stormwater Control In Rangeland Applications, Braden Alan Whitehead

Master's Theses

Diclofenac (DCF) and other emerging contaminants have been found in environments worldwide. These contaminants may enter the environment due to the application of treated wastewater, biosolids and direct excrement related to veterinary application. Leakage from the soils toward the groundwater is largely controlled by sorption and microbial degradation. Most studies on the environmental fate of DCF have focused on degradation during wastewater treatment processes. However, little is known about their behavior in soil. In this study, the combined effect of adsorption and degradation of diclofenac has been investigated in four (4) 24 ft3 agricultural soil-filled beds designed to mimic …

Subclinical Atherosclerosis Quantified Through Cumulative Shear Measurement, Margaret Lynne Papka Aug 2021

Subclinical Atherosclerosis Quantified Through Cumulative Shear Measurement, Margaret Lynne Papka

Master's Theses

With the high mortality rate of cardiovascular disease, it is important to study the early signs. The early detection of cardiovascular disease can lead to saved lives. Currently the most prevalent detection methods are the Framingham Risk Score and the carotid intima media thickness, both of which are insufficient. The necessary tool for early detection requires a uniform quantification system. The stimulus leading to endothelial dysfunction, the most significant predictor of a major adverse cardiovascular event (MACE)—and subsequently subclinical atherosclerosis—is reduced shear stress. Increased surface relative roughness affects the flow profile transition from laminar to turbulent resulting in reduced shear …

Forgotten Crime And Cultural Boom: New York And Brazil's Coffee Trading Relationship In The Early Twentieth Century, Collin Green

The Forum: Journal of History

In the United States of America, coffee and its ever-evolving culture has become a focal point of everyday life. However, we did not just stumble upon this phenomenon; the popularity of coffee was carefully calculated by leaders of the wealthiest coffee companies of the early 20th century in America’s biggest city, New York. In this paper, the history of the powerful coffee trading relationship between Brazil and New York is analyzed on two different levels. Firstly, I examine how New York's big coffee companies successfully participated in criminal activity on an international and national level. Secondly, my focus shifts to …


Not So Dystopian: A Historical Reading Of Eugenics In Science Fiction, Riley Sanders Jun 2021

Not So Dystopian: A Historical Reading Of Eugenics In Science Fiction, Riley Sanders

The Forum: Journal of History

Broadly, this paper is an effort in complicating traditional readings of eugenic themes in science fiction. Two landmark novels, Wells’ The Island of Dr. Moreau (1896) and Huxley’s Brave New World (1932), are highlighted as representative of the early and late stages of eugenics. By focusing on the troubling historical context surrounding these authors, I denounce the simple reading of these works as merely “dystopian”. Scholars like Francis Fukuyama advance these simplistic readings by instinctively assuming that Wells and Huxley were against eugenics. This paper continues the tradition that David Bradshaw popularized in his book The Hidden Huxley, which argues …


Stigma On Campus: The Precarious Situation Of Iranian Students At Cal Poly, November 1979, Chance Coates Jun 2021

The Forum: Journal of History

Exploring the ways in which the seizure of the American embassy and subsequent hostage situation of American nationals within Tehran in 1979 transcended international boundaries, this paper discusses the backlash that Iranian students at Cal Poly faced during this pivotal geopolitical crisis. In doing so, I review various protests and public statements that gave rise to a distinct social discourse that stigmatized Iranian students, effectively transforming this group into an “Other.” Further, I explore the ways in which the university as an institution contributed to this stigmatization. The paper overall concludes that the Iranian students on campus were, like the …


The Purpose Of Shanties From The Time Of Sailors To The Musical Masters Of The Twentieth Century, Madison Grant Jun 2021

The Purpose Of Shanties From The Time Of Sailors To The Musical Masters Of The Twentieth Century, Madison Grant

The Forum: Journal of History

The folk songs of the high seas traveled across hundreds of ships, changed in sound and lyric, and ultimately became known today as maritime folk music. Although many historians choose to analyze maritime history through physical artifacts, one less-appreciated aspect of the sea is known as the sea shanty. With modern musicians paying homage to their older nautical counterparts, the revival of shanty tunes sprung forth an almost lost appreciation into the lives of both historians and musicians alike. Referenced in this essay is the James Madison Carpenter Collection, an array of recorded and inscribed sources of shanty tunes that …

Los Zetas, Neoliberalism, And Popular Opposition: A Study In Linkages, Gina R. Lyle Jun 2021

Los Zetas, Neoliberalism, And Popular Opposition: A Study In Linkages, Gina R. Lyle

Master's Theses

Los Zetas are considered by security analysts to be a transformative force within transnational criminal organizations (TCO), exporting their unique model throughout Mexico. Los Zetas’ idiosyncratic interventions include their diversification of criminal operations, professionalization of TCO security, sophisticated use of media and technology, extreme forms of violent coercion, and decentralized command structure. This project aims to complicate the narrative that Los Zetas emerged because of top leaders’ sadistic tendencies or due to an inherently violent culture in Mexico by reframing the group’s evolution within historical processes. Moving beyond Los Zetas, this project examines how persons affected by Los Zetas’ indiscriminate …


Upending The "Racial Death-Wish": Black Gay Liberation And The Culture Of Black Homophobia, Kailyn Pope Jun 2021

Upending The "Racial Death-Wish": Black Gay Liberation And The Culture Of Black Homophobia, Kailyn Pope

Master's Theses

This thesis analyzes the origin and impact of Black homophobia found in activist spaces of mid- to late-twentieth-century American society. Black gay Americans were subjected to intersecting forms of systemic and cultural oppression that were exceedingly hard to escape due to both the homophobia in Black spaces and the racism in gay spaces. Black gay activists and artists thus had to create their own avenues of expression where they and others could fully embrace what it meant to be Black and gay. This work utilizes a Black feminist framework to explore the roots of Black homophobia and how this type …

Effects Of Plant Growth-Promoting Bacteria And Fungi On Strawberry Plant Health, Fruit Yield, And Disease Susceptibility, Mary Maher Jun 2021

Effects Of Plant Growth-Promoting Bacteria And Fungi On Strawberry Plant Health, Fruit Yield, And Disease Susceptibility, Mary Maher

Master's Theses

Studies on plant growth-promoting rhizobacteria (PGPR) and fungi (PGPF) as biostimulants have shown significant positive effects on plant health, fruit yield, or pest management. However, very few published studies to date have been specific regarding their effects on strawberries (Fragaria × ananassa), particularly on soilborne disease prevalence in organically grown strawberries. Empirical data on the results of using these products in commercial growing applications under various conditions would be highly valuable, especially for organic growers who have limited synthetic chemical pesticides, herbicides and fertilizers registered for use. The objective of this study is to evaluate the efficacy of …


The Effect Of Reaction Conditions On The Nucleation And Particle Growth Of A Colloidal Covalent Organic Framework, Brendan Posson Jun 2021

The Effect Of Reaction Conditions On The Nucleation And Particle Growth Of A Colloidal Covalent Organic Framework, Brendan Posson

Master's Theses

Covalent organic frameworks (COFs) are a novel class of crystalline materials with regular porosity, high specific surface area, and various linkage chemistries. Conventional chemical syntheses of these materials lead to the formation of bulk powders characterized as polycrystalline aggregates. Synthesizing these materials as colloidal systems is an effective means to prevent aggregation and achieve larger single-crystalline domain sizes. In this thesis, I describe the effect of temperature and transimination catalyst strength on COF particle nucleation and particle growth. Morphology and crystallinity of the COF-300 particles were confirmed using X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The onset of colloidal …
