Valley Bottom Inundation Patterns In Beaver-Modified Streams: A Potential Proxy For Hydrologic Inefficiency, Karen Bartelt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For centuries river management and land use actions in North America have caused widespread stream degradation where water now flows downstream with artificially high efficiency. When present, beaver dams slow the flow of water and decrease the efficiency of water conveyance through the landscape. These effects are often to the benefit of the function of natural physical processes and ecology of the stream. The benefits provided by beaver dams have been well studied at small scales, but the methods that these studies rely on are often expensive and time consuming and consequently not feasible to deploy at larger spatial scales …

Achieving A Sequenced, Relational Query Language With Log-Segmented Timestamps, M. A. Manazir Ahsan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a relational temporal database, typically each row of each table has a period timestamp to indicate the lifetime of that row. In order to evaluate a query in a temporal database, sequenced semantics comes into play. The semantics stipulates that the query must be evaluated simultaneously in each time instant using the data rows available at that point of time. Existing researches have proposed changes in the query evaluation engine to achieve sequenced semantics. In this paper we show a way to support sequenced semantics without modifying the query engine. We propose a noble construction log-segmented label to represent …

Injection Of Iodoacetic Acid Into Pre-Rigor Bovine Muscle Simulates Dark Cutting Conditions, Jared Forrest Buhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Following the harvest of an animal, muscle will continue to produce energy in an attempt to stay alive, primarily through the pathway of glycolysis. This occurs in the form of anaerobic (oxygen-free) metabolism of glucose and glycogen, which causes the meat to acidify. This acidification process is important for proper meat quality development and when insufficient glycolysis occurs it can cause a meat defect known as dark cutting. This defect causes the color of the muscle to become very dark, increases the water-holding capacity of the meat, and causes it to feel firm and dry on the surface because the …

Balance Control And Exercise-Based Interventions In Older Adults, Youngwook Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Loss of balance and consequential falling, caused by natural degenerations in the sensory and motor systems with aging, are critical issues that require constant research exploration to ultimately improve the quality of life in older populations. Balance can be simply classified into static and dynamic balance, and the latter is more associated with common causes of falling in older adults. There are numerous ways to improve dynamic balance, and exercise training has been considered the most beneficial intervention for that purpose. Specifically, aquatic exercises have been suggested as a promising modality because several properties of water, including buoyance and hydrostatic …

Candidate Ideology And Small Donor Contributions, Ryan Kobe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

While individual citizens are the biggest source of campaign fundraising in Senate and House elections, previous research has focused on individuals donating over the reporting limit of $200. The Federal Elections Committee now makes available data on individuals who donate less than $200, and as these donors take on a bigger role in congressional fundraising, a new analysis of donor motivations is needed. This thesis investigates if and how candidate ideology is related to amount contributed. Specifically, I ask whether the dollar amount of contributions changes depending on how conservative or liberal a candidate is. These results have important implications …

Through the course of this research the conclusion asserts that Mustafa Kemal Ataturk was a more capable man than Soleimani to ascend to a position …

A Comparison Of The Ecology Of Resident And Translocated Beavers Used For Passive Restoration In Degraded Desert Rivers, Emma Doden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ecosystem engineers are species that create, destroy, modify, or maintain habitat. As ecosystem engineers, beavers have the potential to assist in stream restoration. Translocation is the capture and relocation of an animal to another area. Translocation of nuisance beavers has become a popular method to reduce human-wildlife conflict and restore waterways. However, few projects monitor beavers after release and compare behavior to naturally occurring resident beavers. Translocations to desert rivers are also rare. We captured, tagged, and monitored 47 beavers which we translocated to desert river restoration sites on the Price and San Rafael Rivers, Utah, USA. We compared translocated …

The Effect Of Bit Depth On High Temperature Digital Image Correlation Measurements, Steven Robert Jarrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Digital Image Correlation (DIC) is a camera-based method of measuring mechanical displacement and strain which is commonly used in high-temperature experiments due to its ability to take contactless measurements. High-temperature DIC is challenging due to light emitted from the sample which can saturate the camera sensor. Blue-DIC and UV-DIC have been developed to minimize this effect, but the maximum sample temperature range of DIC remains a function of the camera and camera settings. Bit depth, also referred to as color depth or number of bits, is an important camera setting which affects the dynamic range of an image, but which …

Transformation Groups And The Method Of Darboux, Brandon P. Ashley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the study of partial differential equations (PDE), one is often concerned as to whether or not explicit solutions can be obtained via various integration techniques. One such technique, known as the method of Darboux, has had particular success in solving nonlinear problems as demonstrated by the classical works of Goursat. Recently, Anderson, Fels, and Vassiliou provided a far-reaching generalization of Vessiot’s group-theoretic interpretation of the method of Darboux. This generalization allows for the characterization of Darboux integrable systems in terms of fundamental geometric invariants as well as the construction of Darboux integrable systems in general.

In this work, we …

Methods To Improve Our Understanding Of Aspen Regeneration And Aspen Distribution Across The Intermountain West, Robert Joseph Julius Bidner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quaking aspen (Populus tremuloides) is the dominant broadleaf tree and an ecologically important species at upper elevations in the Intermountain West. Recent large-scale forest mortality events have raised questions about how physiological and climatic factors influence aspen’s distribution across the western U.S. Aspen is particularly well-known for reproducing asexually from its root sprouts, leading to the formation of large clonal stands. In addition, as a wind-dispersed species, aspen sexual reproduction plays an important role in how it is distributed at a landscape scale. My research focuses on questions relating to both sexual and asexual reproduction of aspen.

Intraspecific Variation In Prey Susceptibility Mediates The Consumptive Effect Of Predation: A Case Study Of Yellowstone Elk And Wolves, Lacy M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reintroduction of wolves (Canis lupus) to Yellowstone National Park starting in 1995 is an important case study for understanding the consequences of predation on a prey population. Simulation studies conducted prior to and shortly after wolf reintroduction predicted that wolf predation of elk (Cervus canadensis) would have a modest influence on elk abundance. Predation of elk by wolves has been well documented and elk have remained the primary prey for wolves despite a decline in elk abundance. I used two quantitative approaches to estimate the influence of wolf predation on adult female elk survival and …

Efficacy Of Professional Development Models In Dismantling Scientific Misconceptions, Tyler Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scientific misconceptions held by educators are both common and well documented. As science education becomes more and more important to students, it is evident that there is a need to not only identify scientific misconceptions held by teachers as a means of bettering the education of students, but also determine effective methods of deconstructing them. Although studies have indicated that professional development can assuage the prevalence of misconceptions held by teachers, there is a dearth in the literature of what makes these professional developments effective. Therefore, this study investigated which models of professional development are most effective in dismantling misconceptions …
