Micro-Biosensor Devices For Biochemical Analysis Applications, Han Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A biosensor is an analytical device integrating a biological element and a physicochemical transducer that convert a biological response into a measurable signal. The advantages of biosensors include low cost, small size, quick, sensitivity and selectivity greater than the conventional instruments. Biosensors have a wide range of applications ranging from clinical diagnostics through to environmental monitoring, agriculture industry, et al.

The different types of biosensors are classified based on the sensor device as well as the biological material. Biosensors can be broadly classified into (piezoelectric, etc.), electrochemical biosensors (potentiometric, amperometric, etc.), and optical types of biosensors (fiber optics, etc.).

Pollution Prevention And Water Reuse At Utah Department Of Transportation Facilities, Amanda Stoudt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As stormwater flows over roads, sidewalks, and other impervious surfaces, it picks up pollutants that are deposited on these surfaces. One common pollutant transported by stormwater is road salt. While the application of road salt is crucial for wintertime public safety, road salt has a host of negative environmental impacts. Road salt has been linked to increasing levels of dissolved solids in groundwater, vegetation damage, and behavioral changes in aquatic organisms. Studies have shown that these impacts are concentrated around salt storage facilities. As a result, the United States Environmental Protection Agency issued many state departments of transportation municipal separate …

Abstention And Costly Information Acquisition In Elections, Jacob Meyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Voter turnout rates are low in the United States. Even among citizens who show up to the polls, many do not vote in every race on the ballot. This is especially true for low-profile elections, and races where political party is not on the ballot. Both low turn out and incomplete ballots could be caused by high costs of information. Voters and non-voters have time constraints that can prevent them from researching every candidate or proposition on the ballot. One proposed solution to increase citizen informedness is to make voting mandatory. Mandatory voting imposes a penalty (usually a fine) if …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore relationship between individuals’ characteristics, experiences, personality traits, and thought processes in the contexts of casual sexual behaviors. According the principles of Sexual Script Theory, personality traits and personal thought are creations of cultural beliefs and individual experiences. A sample of 1,142 emerging adults between the ages of 18-24 who had a hooking up experience (i.e., sexual activity outside of romantic relationships).

It was found that the emerging adults in this study could be grouped into three (3) distinct groups based upon their personality traits and their motivations for hooking up. The first …

Arsenic Release From Surface Soils Induced By Stormwater Bioretention, Kaisa H. Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Arsenic is a naturally occurring element known for its chronic and acute toxicity. The solubility of arsenic is highly dependent on environmental conditions. The soils of Cache Valley, UT, contain naturally occurring arsenic.

Bioretention systems rely on a combined plant-soil system to remove pollutants carried by stormwater, typically nitrogen, phosphorus, dissolved organic carbon, and select metals. Phosphate from stormwater potentially increases arsenic mobility, which makes stormwater pollutant loading an important factor for evaluating risks associated with stormwater bioretention. Pollutant removal in these systems occurs through sorption of contaminants onto the soils, physical filtration by the soil media, and uptake by …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tweets containing the popular hashtag #ThisIsWhatAnxietyFeelsLike were analyzed in this study. Six themes emerged from our phenomenological analysis of relational experiences with anxiety as conveyed by the Twitter users including: (a) deflated self in relation to others and their perceptions; (b) fear, worry and avoidance behaviors that influence relationships; (c) negative emotional responses leading to feeling misunderstood, lonely, and like a failure (self-fulfilling prophecy); (d) social triggers; (e) anxiety management strategies; and (f) things for others to avoid. This paper will highlight how anxiety symptoms affect relationships and interactions with others, and implications for clinical work and future research.

The Environmental Impact Of Immigration In The United States, Guizhen Ma

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth increases pressure on the environment. Immigration may be harmful to the environment because it is the major force of population growth in the United States. However, this argument has not been supported by research findings. A few studies on this topic show that locations with higher numbers of immigrants experience better air quality than locations with greater proportions of U.S.-born residents. This research investigated the environmental impact of immigration through three independent studies. First, I tested the relationship between U.S.-born population, foreign-born population, and air quality across all the U.S. continental counties. This study analyzed the air quality …

Model-Based Properties Of Earth's Protective Shield: Relating Ut-Based Dependencies Of The Open/Closed Boundary, Cutoff Latitude, And L-Shell Parameter With Polar Cap Absorption Events, David A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

High frequency radio continues to be an important communications medium. For example, commercial airlines use high frequency radios as their primary communications mode during transpolar crossings. It has been estimated that over 7000 transpolar flights occur each year. Unfortunately, during geomagnetic storms high frequency communications can become unreliable, especially near Earth's Polar Regions.

Space weather forecasters are burdened with the responsibility of predicting how radio signals might be affected during geomagnetic storms and passing that important information on to commercial airlines, allowing them to adjust flight plans accordingly. Such adjustments can be costly, but are necessary to ensure safety of …

Family Development And The Marital Relationship As A Developmental Process, J. Scott Crapo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the commonly held idea that families develop, there is not a theory in common use within the family science field that is developed specifically for the study of the development of the family. Family development theory, developed in the post-World War II era, was used previously, but an inability to be adapted to contemporary families and a lack of scientific utility have kept it from use. Additionally, research on how families develop has not considered how relationships may develop over time.

In this dissertation, I seek to address these holes in the family studies field. I do this over …

Effect Of Thermosonication On Viscosity Of Milk Concentrates And Milk Quality And Shelf Life, Vidita Deshpande

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thermosonication is the application of soundwaves at temperatures ≥50°C. It can be used to improve functional properties, overall quality, and shelf life of dairy products. Milk is concentrated before being spray dried and currently milk concentration is limited by increased viscosity. Decreasing the viscosity of concentrates prior to spray drying could be economically beneficial to dairy processors. Results from this study showed that that thermosonication significantly reduced the viscosity of concentrates such as reconstituted milk protein concentrate (rMPC) and reconstituted skim milk powder (rSMP). This would allow for spray drying of these concentrates at a higher total solids with a …

Rural Sustainability In The Intermountain West, Mary L. Oliver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Assessing the sustainability of communities is important for planners and citizens alike. Sustainability plays a central role in forming healthy, successful communities and in planning for responsible growth and development. Most current sustainability evaluations favor urban environments due to their high densities and resulting efficiencies, leaving rural areas labeled “unsustainable” because of their decentralized growth patterns. Characterized as “not urban,” they fall short of urban sustainability benchmarks (Isserman, 2005). The importance of rural sustainability to both small communities and regions leads to the question: how can rural sustainability be characterized and assessed?

This study applies a comparative assessment model to …

From Theory To Practice: Establishing The Classroom As The Setting For Race Talk Through The Intentional Analysis And Discussion Of Poems By Authors Of Color, Cree Taylor

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Modern-day racism exists in mostly subtle ways and is often felt most keenly in the classroom. When schools began the legal integration process in 1954, Black teachers were fired, all-Black schools were closed, and Black students were bused to the formerly all-White schools. In this new environment, Black students and all Students of color were forced to accept and adapt to an educational system that favored Whites over all other racial groups. Today, White Supremacy in education affects the establishment of state and national standards, school and district boundaries, and the un-fair disciplinary action taken against Students of Color. In …

Harvest: Poems, Brittney Allen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Louise Glück wrote, “the actual making of art is a revenge on circumstance.” The risk, she goes on, is in the possibility of shame. Writing poetry then becomes an act of courage, purchased with sacrifice or loss. “Courage, in this usage, alludes to a capacity for facing down the dark forces.”

In Harvest, a poetry chapbook, the speaker takes revenge on the circumstances of her life by being blunt, bare, and brave on the page. She contends with a male-dominated society and abusive childhood as she moves into adulthood and the supposed saving grace of a marriage. The speaker confesses …

Salinity Tolerance In Kentucky Bluegrass Hybrids, Paul G. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diminishing water sources in the Intermountain West have led to increased use of alternative sources of water. These sources, such as reclaimed water, generally have elevated salinity levels that may slow growth, and cause a decline in turfgrass quality. Kentucky bluegrass (Poa pratensis L.) is sensitive to salt stress, but is otherwise very well adapted to many turfgrass areas because of its dark color, durability, ability to recover from wear, and soft texture. Because of these positive traits, it has been the subject of selection for salt tolerance. This study was designed to evaluate the salt tolerance of hybrids …

Acute Mechanical Stress In Primary Porcine Rpe Cells Induces Angiogenic Factor Expression And In Vitro Angiogenesis, Farhad Farjood, Amir Ahmadpour, Sassan Ostvar, Elizabeth Vargis

Biological Engineering Faculty Publications

Background

Choroidal neovascularization (CNV) is a major cause of blindness in patients with age-related macular degeneration. CNV is characterized by new blood vessel growth and subretinal fluid accumulation, which results in mechanical pressure on retinal pigment epithelial (RPE) cells. The overexpression of RPE-derived angiogenic factors plays an important role in inducing CNV. In this work, we investigated the effect of mechanical stress on the expression of angiogenic factors in porcine RPE cells and determined the impact of conditioned medium on in-vitro angiogenesis.

Results

The goal of this study was to determine whether low levels of acute mechanical stress during early …
