Utilizing Legumes To Improve Production And Nutritive Value Of Intermountain West Pastures, Jacob T. Briscoe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pastures in the Intermountain Western United States mainly consist of cool-season grasses which lack production without supplemental nitrogen. Legumes provide nitrogen at reduced cost compared to nitrogen fertilizer. There is a need for proven methods of inter-seeding legumes into existing cool-season grass pastures as well as knowledge of how animals prefer legumes to grasses and how the nutritive value of forages change throughout the growing season. This research provides a resource for effective integration of legumes into pastures of the Intermountain West. Alfalfa, birdsfoot trefoil, and cicer milkvetch were inter-seeded into existing cool-season grass pastures following pretreatments of light tillage, …

Using Social Network Analysis To Examine The Intersection Of Adolescent Friendships And Health Behavior, Emily Long

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescence marks a vulnerable developmental period for health behavior, and research demonstrates that social context and interpersonal relationships impact the health behavior choices of adolescents. In addition, theories of adolescent development suggest a bidirectional relationship between environmental factors, including social relationships, and health. Friendships are one of the most salient relationships during adolescence, and new methods from the field of social network analysis allow researchers to explicitly examine the mechanisms through which friends influence health behavior, and simultaneously, how health and health behavior impacts the formation of friendships. Importantly, social network methods (e.g., stochastic actor-based models, exponential random graph models) …

"Full On Toy Story": Exploring The Belief In Object Sentience In Western Culture, Amelia Mathews-Pett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis considers, from a folklorist’s perspective, the people in Western society who believe that everyday objects have feelings. It establishes these people as a cohesive group for study, referred to as “people to experience the belief in object sentience,” then analyzes their personal accounts of the experience to find both commonalities and differences. From this analysis and discussion of folkloristic perspectives on belief, the main argument is established: people in this group have generally been marginalized and could benefit from a more careful consideration of their beliefs.

Comparative Pollination Efficacies Of Bees On Raspberry And The Management Of Osmia Lignaria For Late Blooming Crops, Corey J. Andrikopoulos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Unlike other rosaceous fruit crops such as apple and cherry, commercial raspberry cultivars are largely self-fertile and can set fruit in the absence of pollinators. However, their floral morphology often prevents complete self-pollaintion. Incomplete pollination yields unmarketable small or crumbly fruits. Insect visitation is therefore essential to maximizing raspberry yield. Honey bees are typically used to pollinate commercial raspberry; however, escalating prices for hive rentals coupled with increasing acreage encourage evaluation of other manageable pollinators. Bumble bees (Bombus spp.) and several mason bees (Osmia spp.) are promising raspberry pollinators. Five bee species were evaluated and compared for their …

Using Anthropogenic Risks To Inform Salmonid Conservation At The Landscape Scale, Andrew W. Witt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The expansion and industrialization of humanity has caused many unforeseen consequences to the natural world. Due to the importance of freshwater for people, rivers have been particularly altered to meet human needs, often at the expense of the natural world. Supplying water for farms, industries, and cities has reshaped the natural state of rivers by altering river paths, chemistry, and species compositions. These changes have harmed many species that prospered before widespread human alterations, including the native trout and salmon of western North America. As human populations continue to grow, new threats will surface for rivers, and the trout and …

Gps Denied Localization Using Ultra-Wideband Radios, Joshua P. Vanfleet

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

GPS denied environments cause each unmanned ground vehicle (UGV) in an autonomous convoy to lose positional accuracy which can lead to inoperability, or even damage. In order for autonomous convoy systems to fill the needs of any particular field, a well-performing system must be designed such that a convoy can operate in any environment. Ultra-wideband (UWB) radios are a proposed solution to GPS denied localization. The main objective of this research is to use UWB radios to localize a leader vehicle within a convoy situation while in a GPS denied environment.

Understanding Plant Secondary Metabolites; Above And Below Ground, Andrea K. Clemensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants naturally produce primary and secondary metabolites. Primary metabolites are directly involved with plant growth and metabolic function. Plant secondary metabolites (PSM) were once thought of as metabolic waste products, and more recently viewed as toxins to herbivores. However, ongoing research shows that PSM are beneficial to herbivores at low doses, and PSM aid plants by attracting pollinators, recovering from injury, protecting from ultraviolet radiation, increasing drought tolerance, and aid in defense against pathogens, diseases, and herbivores. Plant secondary metabolites also influence soil nutrient cycling, and can increase the sustainability of agroecosystems. Endophyte-infected tall fescue (Festuca arundinacea Schreb.), which …

Ultraviolet Diffraction Assisted Image Correlation (Uv-Daic) For Single-Camera 3d Strain Measurement At Extreme Temperatures, Ethan K. Nickerson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Digital Image Correlation (DIC) is a technique which uses images taken before and after deformation to determine displacement and strain data over the surface of the sample. In order to obtain this data for both in-plane as well as out-of-plane direction, multiple views of the sample are required. Typically, this is accomplished using multiple cameras, but it is possible to use diffraction gratings to bend the light coming from the specimen in order to allow a single camera to capture multiple views. This technique is referred to as Diffraction Assisted Image Correlation (DAIC) and has been previously demonstrated at room …

Impact Of Basal Diet On Obesity Phenotype Of Recipient Mice Following Fecal Microbiome Transfer From Obese Or Lean Human Donors, Daphne Michelle Rodriguez Jimenez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The composition of the gut microbiome can be affected by environmental factors, such as diet. The Western dietary pattern is associated with microbiome dysbiosis and adverse health outcomes, including obesity and metabolic disorders. The objective of this study was to examine the effect of gut microbiota from lean or obese human donors on metabolism and weight gain in recipient mice fed one of three basal diets: 1) the standard AIN93G diet, which promotes rodent health; 2) the total Western diet (TWD), which mimics the American dietary pattern and promotes inflammation-associated colorectal carcinogenesis; and 3) a 45% high fat diet-induced obesity …

Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extreme heat events are the deadliest natural hazard in the United States and will continue to get worse in the coming years due to the effects of climate change. As a result, more people will experience deadly heat conditions. This highlights the need for decision-makers to develop better strategies for preventing future losses. How badly individuals are affected by extreme heat depends on many circumstances, such as how high temperatures actually are, weather conditions, and location. For example, a dry 90 °F day in Phoenix is probably more tolerable than a humid 90 °F day in New Orleans for most …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Integrating real data into a classroom is one of the recommendations in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) college report which lays out guidelines for an introductory statistics course (Committee, GAISE College Report ASA Revision, 2016). In order to assess the effect of using real data in a classroom, the students received physical activity trackers to wear during an undergraduate introductory statistics course taught in the summer. This tracker, a Fitbit, enabled students to monitor and record their steps, calories, and active time throughout the class. Collecting personal activity data (PAD) creates a large database which …

A Complicated Peace: Nationalism And Antisemitism In Interwar Poland, Joanna Dobrowolska

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examines the roots of antisemitic rhetoric expressed by Polish nationalists between 1918 and 1939. I argue that nationalist rhetoric and political campaigns during this period focused on calling for Poles to defend themselves against Jewish economic and political domination. The first half of this work utilizes pamphlets, books, newspaper articles, and other written works wherein Polish nationalists, in particular members of the National Democratic Party(NDP), expressed a fear of Polish Jews and called for their eviction from the country. Fear that Poland, a country that had been partitioned by surrounding empires for the past two centuries, would not …

On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thermal bowing, often referred as bulging or out-of-plane wall deflection, is a common issue on sandwich panel walls caused by a temperature differential between a building interior temperature and the environment. The stresses caused by temperature changes in concrete members are widely known in the practice of bridge design, but not on sandwich wall panels. For sandwich wall panel applications, it is common to have non-composite panels when the designer expects a high temperature gradient, what yields a less economical design, but reduces the bowing.

This project aimed to validate current assumptions regarding the heat flow in sandwich wall panels …

Relationships Among Invasive Coqui Frogs, The Small Indian Mongoose And Rat Species In Hawaii, Shane A. Hill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Non-native species are increasing globally, and with this increase, it is likely that there will be new, unique relationships found among non-natives as well as additional impacts on native species. Rats and mongooses have been introduced to islands throughout the world where they impact native species, including birds, reptiles, and amphibians. The coqui frog was introduced to Hawaii in the 1980’s, where there were already abundant rat and mongoose populations. Previous research suggests that the high densities of coqui frogs may provide enough of a new food source for mongooses and rats that their populations would grow larger than they …

Split Latency Allocator: Process Variation-Aware Register Access Latency Boost In A Near-Threshold Graphics Processing Unit, Asmita Pal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the last decade, Graphics Processing Units (GPUs) have been used extensively in gaming consoles, mobile phones, workstations and data centers, as they have exhibited immense performance improvement over CPUs, in graphics intensive applications. Due to their highly parallel architecture, general purpose GPUs (GPGPUs) have gained the foreground in applications where large data blocks can be processed in parallel. However, the performance improvement is constrained by a large power consumption. Likewise, Near Threshold Computing (NTC) has emerged as an energy-efficient design paradigm. Hence, operating GPUs at NTC seems like a plausible solution to counteract the high energy consumption. This work …

Assessment Of Microchimerism Following Somatic Cell Nuclear Transfer And Natural Pregnancies In Goats (Capra Aegagrus Hircus), Kirsten Karen Gash

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Somatic cell nuclear transfer (SCNT) is a powerful tool for production of transgenic animals for various biomedical and agricultural applications. For instance, our group is using SCNT to produce transgenic goats to study the role of cardiac fibrosis in initiation and progression of atrial fibrillation. There is a possibility of cell transfer from a transgenic fetus to its non-transgenic surrogate mother, known as fetal microchimerism; from a transgenic mother to non-transgenic fetus, maternal microchimerism and from a transgenic twin to non-transgenic twin in utero. Initially, we have assessed the presence of fetal microchimerism in tissue samples from non-transgenic surrogates …

Integrated Management Of Billbugs (Coleoptera: Dryophthoridae) In Intermountain West Turfgrass, Madeleine M. Dupuy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Billbugs are a serious pest of turfgrass in the Intermountain West. Billbug larvae severely discolor and eventually kill turfgrass by feeding in stems, on roots, and on crowns of the plant. Billbugs are typically managed with preventive, calendar-based applications of insecticides. Most of our knowledge on the biology and management of billbugs comes from research in the eastern U.S, and little is known about billbug biology and best management practices in the Intermountain West. First, I examined the seasonal activity of billbug life stages in Intermountain West turfgrass and developed a predictive degree-day model to better time management strategies against …

Conformal Inkjet Printed Antennas For Small Spacecraft, Muhammadeziz Tursunniyaz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although small spacecraft are small in size and light in weight compared to the conventional satellites, they can offer lots of possibilities for space exploration, scientific observation, data collection and telecommunication. Also, they cost a lot less money than the conventional satellites, and the scientific missions can be planned in a relatively short period of time by using the COTS (Commercial Off-The-Shelf) materials. However, there is a big challenge for the small spacecraft that is the limited surface area of the small spacecraft and the outnumbered components to be mounted on the surface of the small spacecraft. The most obvious …

Investing In Agribusiness Stocks And Farmland: A Boom Or Bust Analysis, Asif Rasool

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As intelligent investors, we should always consider holding assets of different classes. Investing in assets from various classes allows us to minimize portfolio risks. In this paper, we recommend a better way of devoting money, especially for the investors who are interested in the agricultural sector. Historically fund managers use Markowitz framework to create financial portfolios. However, that framework has some fundamental limitations. A copula is a modern approach that counters the disadvantages of the Markowitz framework, to deal with portfolio construction. Copula also identifies the downside risk (the maximum amount of money you can lose) of a portfolio.

We …
