An Object-Oriented Approach For Modeling And Simulation Of Crack Growth In Cyclically Loaded Structures, D. Cojocaru, Anette M. Karlsson

Mechanical Engineering Faculty Publications

We present an object-oriented modeling frame for simulating crack propagation due to cyclic loadings. Central to the approach is that the crack propagates when a user-defined propagation criterion is fulfilled, i.e., the crack propagation rate is not prescribed but predicted. The approach utilizes the commercial finite element software package ABAQUS and its associated Python based scripting interface. The crack propagation is simulated by a generalized node release technique. If the propagation criteria are satisfied in the end of a cycle, the crack is allowed to propagate. The incremental crack growth is inferred from an iterative investigation of the propagation criteria. …

Transforming Perspectives Through Service-Learning Participation: A Case Study Of The College Counts Program, James O. Peacock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A case study has been conducted on the College Counts program, a well-integrated service-learning program, to examine the experiential learning of 10 former participants. It was the objective of this investigation to view the learning of 10 college students, through the lens of transformational learning, as they reflect on their experiences as participants in the College Counts program. Transformational learning theory was used as a lens to determine if high school students have the ability to engage in transformative learning. Students reported in their own voices transformative learning in one or more of the following forms: increased cultural inclusiveness, commitment …

Effects Of Olfactory And Visual Predators On Nest Success And Nest-Site Selection Of Waterfowl In North Dakota., Jennifer S. Borgo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is difficult because predators use differing tactics to locate nests, such as olfactory or visual cues. I investigated several components of waterfowl nest-site selection and success on sites with shelterbelts (planted tree-rows) in North Dakota, during the 2006 and 2007 nesting seasons.

I found that meteorological conditions impacted nest depredation; artificial nests were more likely to be depredated when either temperature or dew point was …

Predator-Prey Relationships And Spatial Ecology Of Jaguars In The Southern Pantanal, Brazil: Implications For Conservation And Management, Sandra Maria Cintra Cavalcanti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Pantanal wetland of Brazil is an important area for the conservation of jaguars (Panthera onca) and a stronghold for the species. Although our knowledge of jaguar ecology has increased since the first field studies in the mid 1980’s, a detailed study of this cryptic species remains challenging. In the following chapters, we investigated the ecology of jaguars in the southern Pantanal of Brazil. In Chapter II, we examined the foraging ecology of jaguars, documenting predation rates, patterns, and species killed. We found individual jaguars differed in the selection of their prey. There were differences in the proportion …

Factors Related To Success And Participants’ Psychological Ownership In Collaborative Wildlife Management: A Survey Of Sage-Grouse Local Working Groups, Lorien R. Belton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Declines of sage-grouse (Centrocercus spp.) across the western United States have prompted the formation of numerous collaborative stakeholder partnerships, known as local working groups. These voluntary groups create and implement local sage-grouse management plans and projects, often in the hopes that their efforts may help avert a federal Endangered Species designation for the bird. Using a mail survey of participants in 54 local working groups, I examined the importance of psychological ownership in working group dynamics. Psychological ownership is conceptualized as a latent, multidimensional variable consisting of responsibility, control, and caring elements. Multiple regression analysis showed early-stage group success, representative …

Inter-Religious Marriage And Migration, Maggie Y. Bohm

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study analyzes the influence of 1) inter-religious marriage and 2) differing levels of church attendance within a married couple on migration behavior. The study draws from previous research on inter-racial marriage for a framework to examine whether there is reason to expect a relationship between migration and inter-religious marriage. We hypothesize that the propensity for migration is higher for inter-religious couples than for couples constituted by individuals of the same religion and for couples who attend church at different frequencies. To examine the hypotheses, this study uses age, education, and length of residence as controls in logistic models.

In the present work, a versatile micromechanics modeling framework, namely, the Variational Asymptotic Method for Unit Cell Homogenization (VAMUCH), has been invented and various micromechancis models have been constructed in light of this novel framework. Considering the periodicity as a small parameter, we can …

Integrating Surface And Sub Surface Flow Models Of Different Spatial And Temporal Scales Using Potential Coupling Interfaces, Alphonce Chenjerayi Guzha

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objective of this research was to develop and utilize a coupled surface water groundwater model to simulate hydrological responses of watersheds. This was achieved by coupling the U.S. Geological Survey (USGS) groundwater flow model, MODFLOW, and the rainfall runoff model, TOPMODEL, in one case study and coupling MODFLOW with a networked version of TOPMODEL called TOPNET in another case study. The model coupling was achieved using the InCouple approach, which utilizes Potential Coupling Interfaces (PCIs) that are abstractions from model flow diagrams that expose only those aspects of a model relevant to coupling. Coupling the rainfall-runoff models to …

Family Involvement In Three Utah Adolescent Residential Treatment Centers, Wesley W. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Family participation in residential treatment for disturbed adolescents has increased over time. A general sense of this movement is that this is beneficial. However, there are no common descriptions of family involvement in residential treatment in the literature. In order to be able to better understand which components of family involvement are most beneficial, we need to first understand how residential treatment centers (RTCs) define and describe family involvement. This study compiled data from interviews with nine participants, one each from administration, therapy staff, and direct care staff level of three northern Utah RTCs that claimed family involvement in youth …

A detailed mathematical analysis of each design was performed. MATLAB code based on the analyses was written. The MATLAB simulations were compared to Agilent Advanced Design System …

Framing Anti-War Theatre: Public Perceptions Of Embedded, Jeremy Gordon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extending research of framing anti-war protest is framed in the public sphere, this study examines theatre critics' reviews and viewers' responses to Tim Robbins' anti-war play Embedded. My research examines how two groups of publics interpreted Embedded: (1) professional theatre reviewers and (2) a sample of Utah State University students. It is important to note that the majority of the students who participated in this study are members of The Church of Jesus Christ of Latter-day Saints (Mormon), a consistently social and political conservative religious sect. Thus, how this specific group of viewers deciphered Embedded is of special …

An Investigation Of The Effects Of Differential Reinforcement Of Alternative Behavior On Students With Mild/Moderate Disabilities In A School Classroom, Katrina Spangenberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the effects of differential reinforcement of alternative behavior (DRA), a behavior reduction procedure, on problem behavior exhibited by three elementary school students in a general education classroom. DRA involves reinforcement of an alternative behavior while withholding reinforcement for the inappropriate behavior. The three participants were classified as experiencing mild/moderate disabilities but received most services (and participated in this research) in a general education classroom. Problem behaviors included off-task, talk-outs, and inappropriate touching. Alternative behaviors included on-task and hand-raising to get teacher attention. Results indicated that DRA decreased off-task and talk-out behavior for two participants, although effects were …

Academic Performance As A Predictor Of Student Growth In Achievement And Mental Motivation During An Engineering Design Challenge In Engineering And Technology Education, Nathan Mentzer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this correlational research study was to determine if students’ academic success was correlated with: (a) the student change in achievement during an engineering design challenge; and (b) student change in mental motivation toward solving problems and critical thinking during an engineering design challenge. Multiple experimental studies have shown engineering design challenges increase student achievement and attitude toward learning, but conflicting evidence surrounded the impact on higher and lower academically achieving students.

A high school classroom was chosen in which elements of engineering design were purposefully taught. Eleventh-grade student participants represented a diverse set of academic backgrounds (measured …

Analysis Of Chemical Bonding In Clusters By Means Of The Adaptive Natural Density Partitioning, Dmitry Yu Zubarev

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Models of chemical bonding are essential for contemporary chemistry. Even the explosive development of the computational resources including, both hardware and software, cannot eliminate necessity of compact, intuitive, and efficient methods of representing chemically relevant information. The Lewis model of chemical bonding, which was proposed eleven years before the formulation of quantum theory and preserves its pivotal role in chemical education and research for more than ninety years, is a vivid example of such a tool. As chemistry shifts to the nanoscale, it is becoming obvious that a certain shift of the paradigms of chemical bonding is inescapable. For example, …

Mountain Pine Beetle Fecundity And Offspring Size Differ Among Lodgepole Pine And Whitebark Pine Hosts, Donovan Gross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whitebark pine (Pinus albicaulis Engelmann) is a treeline species in the central Rocky Mountains. Its occupation of high elevations previously protected whitebark pine from long-term mountain pine beetle outbreaks. The mountain pine beetle, however, is currently reaching outbreaks of record magnitude in high-elevation whitebark pine. We used a factorial laboratory experiment to compare mountain pine beetle (Dendroctonus ponderosae Hopkins) life history characteristics between a typical host, lodgepole pine (Pinus contorta Engelmann), and whitebark pine. We tested the effects of natal host and brood host on beetle fecundity, offspring size, and brood sex-ratio. We reared mountain pine beetles …

Intergranular Phases In Cyclically Annealed Yba2cu3o7-X And Their Implications For Critical Current Densities, Andrew Peter Clarke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We report changes in the intergranular material and grain morphology of YBa₂Cu₃O_7-x during cyclic anneals between 780 and 980 ºC in oxygen at atmospheric pressure. Two endothermic reactions were detected: (a) the eutectic reaction of YBa₂Cu₃O_7-x with CuO and BaCuO₂ at 900 ºC (enthalpy ∆H_a) and (b) the peritectic reaction of YBa₂Cu₃O_7-x with CuO at 950 ºC (∆H_b). During the first anneal, only reaction (b) is detected, and although it should only occur if there is an excess of CuO, …

Utah Off-Highway Vehicle Owners' Specialization And Its Relationship To Environmental Attitudes And Motivations, Jordan W. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Off-Highway Vehicle (OHV) use has grown enormously on Utah’s public lands and is one of the most contentious and difficult issues for federal, state, and local land management agencies to address and provide for. Despite OHV use’s meteoric rise in popularity and its ongoing public conflicts, little is known about OHV recreationists. This thesis develops a typology that identifies within-activity differences related to recreation specialization; it also determines differences in OHV owners’ environmental attitudes and motivations. Findings show Utah’s owners comprise a range of use along the recreation specialization continuum. Results also indicate that an OHV owners’ specialization level is …

Dechlorinating And Iron Reducing Bacteria Distribution In A Trichloroethene Contaminated Aquifer, Carmen Lourdes Yupanqui Zaa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Operable Unit 5 (OU 5) area of Hill Air Force Base currently has two trichloroethene-contaminated groundwater plumes underneath residential areas in Sunset and Clinton, Utah. Bioremediation by biological reductive dechlorination can be an important mechanism for the removal of chlorinated compounds from the plumes. The presence of suitable bacteria to carry on reductive dechlorination is the key in the bioremediation process. The goal of this study was to determine the distribution and population density of the 16S rRNA genes of Bacteria, Dehalococcoides ethenogenes, Desulfuromonas michiganensis, Geobacter spp and Rhodoferax ferrireducens-like bacteria, as well as the functional genes trichloroethene reductive …

The Consciousness Of Damnation : A Hermeneutical Phenomenology Of The Fall Of The Self In Matthew Lewis's "The Monk"., Becky Lee Meadows

Electronic Theses and Dissertations

When Ambrosio in Matthew Lewis's 1796 gothic masterpiece, The Monk , signs a contract relegating his soul to Satan and eternal damnation, he has reached the culmination of 442 pages of mental anguish, of his self wrestling with his conscience to overcome what philosopher Paul Ricoeur terms the "servile will" (The Symbolism of Evil 151). In the novel, Ambrosio, a monk the reader discovers has become the pawn of Satan, hurls himself down a path to damnation in consciousness, a phenomenological path that leads to the damnation of his own self. The purpose of this dissertation is to explore this …

Ethylene Synthesis And Sensitivity In Crop Plants, Joseph F. Romagnano

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The gaseous plant hormone ethylene is a small molecule that regulates developmental change. Research was conducted in three areas: sensitivity, synthesis, and alterations to synthesis. Vegetative pea plants were more sensitive than radish plants to atmospheric ethylene. Light intensity did not affect ethylene sensitivity. Ethylene synthesis rates were measured for unstressed cotton, corn, soybean, and tomato plants. The per-plant ethylene synthesis rate ranged from 0.1-80 pmol plant^-1 s^-1. However, when normalized to net photosynthetic rate, this range was 1-4 µmol of ethylene synthesis per mol of CO₂ uptake. Diurnal cycles in ethylene synthesis were present in …

The Role Of Hsp90 In Pc-12 Cell Survival., Christina Blume Clark

Electronic Theses and Dissertations

The chaperone heat shock protein 90 (Hsp90) regulates physiologically and pathological cellular processes, by binding and stabilizing kinases involved in basal cellular functions and in cellular responses to stress, respectively. I hypothesize that Hsp90 binding to kinases Akt and Raf-l and to co-chaperone Cdc37 and Akt-dependent phosphorylation of Hsp90 regulate PC-12 cell survival. Hsp90 binding was inhibited using the classical Hsp90 inhibitor, Geldanamycin (GA). Disruption of Hsp90 binding by GA correlated with similar cell death at normoxia (RA) and at 0.1 % O2 sustained hypoxia (SH), suggesting that Hsp90 binding plays a role in cell survival. Indeed, GA cytotoxicity is …

Voting System Risk Assessment Via Computational Complexity Analysis, Dan S. Wallach

William & Mary Bill of Rights Journal

Any voting system must be designed to resist a variety of failures, ranging from inadvertent misconfiguration to intentional tampering. The problem with conducting analyses of these issues, particularly across widely divergent technologies, is that it is very difficult to make apples-to-apples comparisons. This paper considers the use of a standard technique used in the analysis of algorithms, namely complexity analysis with its "big-O" notation, which can provide a high-level abstraction that allows for direct comparisons across voting systems. We avoid the need for making unreliable estimates of the probability a system might be hacked or of the cost of bribing …
