Emerging Diseases, Abiotic Disorders, And Macrophomina Root Rot Management Of California Strawberry, Cooper Calvin

Master's Theses

Strawberry is an economically important crop in California, with an estimated value of $2.68 billion in 2023. In California strawberry production, mitigation of low plant health and yield often focuses on major soilborne pathogens, while the contribution of minor pathogens and abiotic disorders to production shortcomings are often overlooked. The objectives of the first project in this thesis are to determine the pathogenicity of multiple minor pathogens and quantify other biotic and abiotic factors that can reduce plant health such as viruses and soil salinity. Two pathogens of the black root rot complex, Pythium spp. and Rhizoctonia spp. as well …

Red Raspberries Attenuate Blood Glucose Spike Of A High Glycemic Load Breakfast Cereal, Dante J. Martin

Master's Theses

Blood glucose (BG) spikes increase chronic disease risk in those with and without diabetes. The fiber and phytonutrient content of fruit, such as raspberries has the potential to attenuate the BG spike of a high glycemic load (HGL) meal. We examined the effect of red raspberries (RRs) on the BG spike when added to a HGL meal. In this randomized cross-over trial, 16 university students were given breakfast cereal and almond milk (control), the control breakfast with 140g added RRs, and the control breakfast with sugar equivalent to the sugar content of the RRs (50% sugar increase from control).

Deciphering The Contribution Of Microglia To Neurodegeneration In Friedreich's Ataxia, Sydney N. Gillette

Master's Theses

Friedreich's ataxia (FRDA) is the most prevalent inherited ataxia, affecting one in every 50,000 individuals in the United States. This hereditary condition is caused by an abnormal GAA trinucleotide repeat expansion within the first intron of the frataxin gene resulting in decreased levels of the frataxin protein (FXN). Insufficient cellular frataxin levels results in iron accumulation, increased reactive oxygen species production and mitochondrial dysfunction. Tissues most heavily impacted are those most dependent on oxidative phosphorylation as an energy source and include the nervous system and muscle tissue. This is evident in the clinical phenotype which includes muscle weakness, ataxia, neurodegeneration …

Morp: Monocular Orientation Regression Pipeline, Jacob Gunderson

Master's Theses

Orientation estimation of objects plays a pivotal role in robotics, self-driving cars, and augmented reality. Beyond mere position, accurately determining the orientation of objects is essential for constructing precise models of the physical world. While 2D object detection has made significant strides, the field of orientation estimation still faces several challenges. Our research addresses these hurdles by proposing an efficient pipeline which facilitates rapid creation of labeled training data and enables direct regression of object orientation from a single image.

The objective of this study was to compare the vertical distribution of water-soluble (WS) soil P and other nutrients from a synthetic-wastewater-derived electrochemically precipitated struvite (ECST) to that from a chemically precipitated struvite (CPST), triple superphosphate (TSP), monoammonium phosphate (MAP), and a control in six soils from Arkansas (AR; loam [L] and silt loam [SiL]), Missouri (MO; SiL 1 and SiL 2), and Nebraska …

Preference Of Dhurrin-Free Sorghum By Ewes, Shelby M. Gruss, Keith D. Johnson, John Scott Radcliffe, Ronald P. Lemenager, Mitchell R. Tuinstra

Animal and Food Sciences Faculty Publications

Sorghum [Sorghum bicolor (L.) Moench] is a resilient forage crop due to its drought tolerance and adaptation to low-N environments. Sorghum produces a cyanogenic glucoside called dhurrin. The breakdown of dhurrin leads to the release of hydrogen cyanide (HCN), which can cause cyanide toxicity in livestock. Dhurrin-free sorghum lines have been developed through chemical mutagenesis by mutagenizing the gene for the first enzyme, CYP79A1, in the biosynthetic pathway. The CYP79A1 mutation was bred into sorghum lines to create a dhurrin-free experimental hybrid. Grazing preference of ewes was assessed when allocated to the dhurrin-free hybrid and three commercial hybrids. Near isogenic …

Snowstorm, Caleb Shafer

Masters Theses

This thesis explores the connection between memory and place-building, focusing on how personal narratives and physical models compress details to reveal their core essence. Memories serve as a bridge between time and space, allowing for a non-linear experience of time and offering a unique perspective on the existence and transformation of places. Although this compression involves some loss, it generates new narratives and insights into life while examining the power structures and cultural systems inherent in representation.

Architecture As A Carbon-Based Practice, Qixin Yu

Masters Theses

Carbon serves as both a silent protagonist and a looming antagonist in the narrative of architecture, shaping not only the physical structures we inhabit but also the ecological legacy we leave behind.

Centuries of human exploitation of the environment have led to climate and material crises. Shifting this dynamic requires action at micro (matter), meso (material), and macro (materiality) levels. Biogenic materials offer significant potential for carbon sequestration and present opportunities for the building industry to collaborate with nature rather than merely extract from it.

This thesis establishes a research and manufacturing practice that prioritizes material innovation, carbon sequestration, environmental …

Modern Times, Will Beattie

Masters Theses

At the intersection of glass, photography and sound lies issues of perspective, framing, and information. These factors as well as the conceptual space between object and image offer an opportunity to explore the way we register narrative through contradicting signifiers. Glass historically has been used as an instrument to reveal spaces, moments, and phenomena previously imperceptible to the human eye. This rendering of previously unseen spaces through language, technology or vision, may work to reorient the viewers’ perspective and allow for a new understanding of the world. The power of disruption as a potential catalyst is central to my studio …

Searching For The Hyperobject: Crystals As Transscalar Vehicles, Jay Costello

Masters Theses

When I touch the street outside my house, I'm touching Los Angeles—a contiguous vector of material bisecting a continent. A slab, a stone, dust and oil, a googolplex of tightly packed anisotropic particles... At nightfall, I sneak to the edge of the highway and break off a piece. 'What does it mean for a worm to be aware of the scale of the planet?' Bruno Latour's evocative questioning of scalar jumps prompts an existentialism that places me somewhere between the hyperlocal and the massively distributed. Like a cosmic traveler floating through the universe, I feel adrift. I look around, grasping …

Small Islands Commons: Retrieving Territory, Identity And Rights In The Bahamas, Fangzhou Zhao

Masters Theses

The Earth’s surface area comprises 71% ocean and 29% land. This vast disparity has led to the conceptualization of the Earth as a collection of interconnected islands, a perspective that challenges traditional views which often portray islands as isolated, marginal, or primitive. These narratives have been further complicated by the effects of climate change, which positions islands as vulnerable and in need of attention.

This research seeks to explore new socio-cultural contracts with territories to achieve bio-socio-spatial justice. It aims to maintain sustainable and equitable relationships between governments and local communities, focusing on addressing historical inequalities. By examining landscape-based strategies …

Memory And Experiential Lab, Yufan Xu

Masters Theses

In the tapestry of our lives, there exist moments and places that we can never revisit, scenes etched into our memories that fade with the passage of time. These experiences and memories are treasures, provide us with an anchor to our past. Unfortunately, many of these moments are like fireflies in the night, here one moment and gone the next. Yet, they remain invaluable, forever etched in our hearts and minds. I wonder if it is possible to trigger cherished past experiences and memories in our daily lives, allowing individuals to re-experience similar moments, thereby nourishing the spiritual world. Therefore, …

Timeless Teachings & Unbridled Possibilities, Ruijie Tai

Masters Theses

I am looking at is process of TRANSLATING AND BRIDGING.

Qi, traditionally understood as the vital force that flows through and animates living beings and the environment, lies at the edge of our perceptual capabilities.

The notion that what we cannot "see" holds significant influence over our world suggests that there are aspects of reality and forces at play beyond our direct sensory experience. AI, with its capacity for analyzing vast amounts of data and recognizing patterns beyond human capability, offers a unique tool for exploring these unseen forces.

The potential of AI to perceive and understand Qi could open …

Spirit Of Place: Examining Chinese Principles Of Place-Making In A Contemporary Urban Context, Junyi Shi

Masters Theses

Cities are carriers of both spiritual civilization and physical space. The concept of Chinese cities has existed for about four thousand years, embodying China’s extensive cultural and philosophical heritage. Feng Shui is a specialized theory in Chinese urban planning. Therefore, discussing Chinese cities inevitably involves examining the role of Feng Shui in urban construction.

However, contemporary Chinese urban planning development has almost abandoned traditional Feng Shui. As a result, Chinese cities have become homogenized by Western models, losing their distinctiveness and cultural expression.

Given this issue, this thesis project will use traditional Chinese philosophy as a foundation to study the …

Through processes of observation, collection, archiving, and re-contextualization, I elevate what is often overlooked as mundane and fleeting. This thesis not only uncovers the narrative potential of ordinary objects but also repositions them as protagonists in their own right, urging viewers to reconsider their conventional roles not as …

Bridge Between Calligraphy And Architect, Tianhao Zhong

Masters Theses

The tradition of calligraphy is divided by time, categorized by eras rather than by years, months, or days. As an art, calligraphy is the tangible manifestation of human spiritual ideals, an organic blend of an individual's calligraphic skills and spiritual philosophy. The strokes and lines of calligraphic art imbue Chinese characters, "carved into a single aspect," with a form of movement, enriched with musical rhythm. The structure of the characters symbolizes the laws of universal movement, embodying a beauty that captures the essence of all, hence known as "the sound of silence" and "the form of the formless." It is …

“Touching The Untouchable”: Time As Material And The Fragmented Self In The Maximodern Era Shori V. Sims © 2024 Shori V. Sims All Rights Reserved Shorisims., Shori V. Sims

Masters Theses

In the conventional division of disciplines, film/video/moving images and stationary sculpture are categorized as formal and conceptual opposites. In my work and in this thesis, I am arguing that moving images constitute a form of sculpture in the style of assemblage by the manipulation of time around them. Yes, the image is flat and stationary on its own: but the cut of time which it represents exists multi-dimensionally (spatially and temporally) to be combined in a collage-like manner. In my practice, moving images constitute a form of assemblage that manipulates time and space in ways normally attributed to sculpture.

Beyond The Rational: Exploring Transrational And Embodied Knowledge Through Ceremony And Nature, Dimitris A. Alexakos

Dissertations, Theses, and Capstone Projects

This thesis explores transrational and embodied knowledge gained through my experience within ceremony and nature. This thesis uses transrational to mean “information and experience that does not readily fit into standard cause and effect logical structure” (Bernstein, 2005, p. xv). By reflecting on personal experiences and embodied sensations during ceremonies in nature, the thesis outlines a framework for exploring transrational and embodied knowledge within nature. I offer heuristics, a phenomenological tool to “explore, focus, and raise awareness” (Alexakos, 2015) to provide context for my experience in nature, ceremonies and ceremonies in nature.

The research investigates transrational and embodied knowledge through …
