The Formation Of The Diminutive In Brazilian Portuguese, Cristina M. Newell
The Formation Of The Diminutive In Brazilian Portuguese, Cristina M. Newell
Theses and Dissertations
Although the Portuguese diminutive has been analyzed for centuries, there is a lack of descriptive experimental data regarding how native speakers form the diminutive including participants from each state in Brazil. For this study, 1,053 native speakers from each of the 26 states and the federal district of Brazil filled out an online survey, providing information about their age, gender, birth state, and current state of residence in Brazil. Participants selected the form(s) of the diminutive which they would use for 60 test words. Results indicate that the most influential factors in the formation of the diminutive are the age …

The Impact Of Inkjet Parameters And Environmental Conditions In Binder Jetting Additive Manufacturing, Trenton Miles Colton
The Impact Of Inkjet Parameters And Environmental Conditions In Binder Jetting Additive Manufacturing, Trenton Miles Colton
Theses and Dissertations
Binder jetting is an additive manufacturing process in which a part is fabricated layer-by-layer using inkjet technology to selectively dispense binder into powder layers in a designated area. The approach gives this process significant advantages over other additive manufacturing processes such as lower cost, capability to print in a wide range of materials, and little to no heat applied. Although binder jetting has many advantages and has been successful implemented in various industries its overall rate of adoption is slow compared to other processes. This is largely due to poor mechanical properties and consistency in printing which stems from a …

Language Maintenance In Utah: Spanish Heritage Speakers' Attitudes And Language Use, Perla Y. Escobar Rodriguez
Theses and Dissertations
The current study quantitatively and qualitatively investigated Spanish maintenance among 45 Spanish heritage language (SHL) speakers in Utah who completed a survey about their linguistic background, their attitudes toward Spanish, their self-rated Spanish proficiency, and their current Spanish usage. Nine participants were also interviewed to expound on their linguistic experience. Previous studies on language maintenance (Alba et al., 2002; Carreira & Kagan, 2011; Lanier, 2014; Lynch, 2000; Mejías et al., 2002; Potowski, 2004; Silva-Corvalán, 1994; Zentella, 1997) have analyzed different sociolinguistics factors that relate to Spanish maintenance and usage in areas with high Hispanic populations. Nevertheless, little research has been …
'Across The Sea': The Narrative Function Of Medieval Bridal Sea Voyages In Marie De France’S “Guigemar” And “Eliduc", Rebekah Olsen
'Across The Sea': The Narrative Function Of Medieval Bridal Sea Voyages In Marie De France’S “Guigemar” And “Eliduc", Rebekah Olsen
Student Works
This paper analyzes the common medieval trope of the sea voyage in Marie de France's medieval romances, "Guigemar" and "Eliduc." Through framing both texts through an ecocritical lens tied to the associated symbolism of water and feminity, the paper highlights the importance of the sea due to it's association with female passivity in the medieval era. However, this paper focuses primarily on the narrative tropes found in the two stories and shows that throughout the lais, Marie both implements and subverts the assumptions of the Medieval sea voyage trope, which is clearly defined in Albrecht Classen’s article “Sea Voyages in …

Figures Of Virtue: Margaret Fell And Aemilia Lanyer's Use Of Decorum As Ethical Good Judgment In The Construction Of Female Discursive Authority, Kirsten Marie Osmani
Theses and Dissertations
Understanding how the Renaissance rhetorical curriculum taught style as behavior makes it possible to unite the study of women writers' identities with formal criticism. Nancy L. Christiansen shows that early modern humanists built on the Isocratean tradition of teaching rhetoric as an ethical practice because they adopted and developed lists of rhetorical figures so extensive as to encompass all human discourse, thought, and behavior. For them, knowing, selecting, and applying these various forms was the ethical practice of good judgment, also called decorum. This type of decorum plays an important role in the rhetorical function of two key texts by …
Minimizer Of A Free Boundary Problem, Mingyan Zhao
Minimizer Of A Free Boundary Problem, Mingyan Zhao
Theses and Dissertations
We study a free boundary problem with initial data given on three-dimensional cones. In particular, we study when the free boundary is allowed to pass through the vertex of the cone, which depends on the cone’s slope, determined by a parameter c. With a mix of analytical and computational methods, we show that the free boundary may pass through the vertex of the cone when c ≤ 0.43.
Spline-Based Contact: Algorithms And Applications, Pulama Bhattacharya
Spline-Based Contact: Algorithms And Applications, Pulama Bhattacharya
Theses and Dissertations
Contact is one of the most challenging nonlinearities to solve in solid mechanics. In traditional linear finite element analysis, the contact surface is only C^0 continuous, as a result, the normal to the contact surface is not continuous. The normal contact force is directed along the normal in the direction of the contact surface, and therefore, the contact force is discontinuous. This issue is tackled in linear finite element analysis using various surface smoothing techniques, however, a better solution is to use isogeometric analysis where the solution space is spanned by smooth spline basis functions. Unfortunately, spline-based isogeometric contact analysis …
Electrocatalytic Oxidation Of Carbohydrates Via Surface Immobilized Viologen, Dallin D.V. Scott
Electrocatalytic Oxidation Of Carbohydrates Via Surface Immobilized Viologen, Dallin D.V. Scott
Theses and Dissertations
Earths most abundant biomolecules, carbohydrates, offer tremendous potential forelectricity production. Carbohydrate fuel cells are electrical fuel cells that can harvest the stored electrons in carbohydrates and offer a cheap and efficient method that could help solve growing energy demands, while providing a renewable green energy source. Viologen-mediated carbohydrate fuel cells have demonstrated the ability to accelerate carbohydrate oxidation while decreasing partial or incomplete oxidation products reducing the electricity production. Subsequent studies suggested polymeric viologen compounds could improve the efficiency by increasing the local concentration of viologen. This thesis presents the utility of surface-immobilized viologen mediators for the oxidation of simple …
Working Knowledge: An Analysis Of Innovation In K-6 Charter Schools, Jennifer Lynn Price
Working Knowledge: An Analysis Of Innovation In K-6 Charter Schools, Jennifer Lynn Price
Theses and Dissertations
This three-article dissertation explores educational innovation in charter schools. A common frame of reference for each article is the consideration of the influence of Dr. Benjamin Bloom's 2 sigma problem--the observation that one-on-one tutoring, though often cost prohibitively expensive, produces outcomes two standard deviations higher than traditional group-directed instruction. The first article is a literature review of the types of charter school innovations most commonly found in the literature and the type of effect those innovations can have on student learning outcomes. The research suggests that three of the top studied new innovations from charters are technology-based virtual schools, specific …
Phylogeny And Visual System Evolution In Sap Beetles (Coleoptera: Cucujoidea: Nitidulidae), Gareth S. Powell
Phylogeny And Visual System Evolution In Sap Beetles (Coleoptera: Cucujoidea: Nitidulidae), Gareth S. Powell
Theses and Dissertations
Coleoptera is currently the most diverse lineage of life on Earth with more than 400,000 described species. The group also contains unbelievable ecological and morphological variation that has been evolving since the early Carboniferous (>350 MYA). The group provides the perfect playground to test evolutionary hypotheses with large-scale phylogenies. First, a newly developed bioinformatics tool is presented that allows for the critical assessment of the stability of phylogenetic nodes with even minor changes in taxon sampling (i.e. a single taxon jackknifed). The tool, TANOS, is capable of performing tests on large genomics-scale datasets. The case study included is a …
Galectin-1: Development Of A Novel Protein Therapy For Lgmd2b, Mary Lorena Vallecillo Munguia
Galectin-1: Development Of A Novel Protein Therapy For Lgmd2b, Mary Lorena Vallecillo Munguia
Theses and Dissertations
Muscular dystrophies are a heterogeneous group of genetic diseases that involve mutations in genes leading to progressive muscular weakness. Limb-Girdle Muscular Dystrophy 2B (LGMD2B) is a subset of muscular dystrophy caused by mutations in the DYSF gene, which encodes for dysferlin protein and has an incidence of 1/100,000-1/200,000 people, or 1/300 people of Libyan Jewish descent. Since there is no effective treatment that can cure or reverse effects of LGMD2B once diagnosed, our goal is to investigate and develop a protein therapy that mitigates effects of this disease in patients. Galectin-1 (Gal-1) is a small, soluble 14.5 kDa protein with …

Microwave-Promoted Iminyl Radical Fragmentations And The Total Synthesis Of Yaku'amide A And Its Simplified Analogues, Concordia Lo
Microwave-Promoted Iminyl Radical Fragmentations And The Total Synthesis Of Yaku'amide A And Its Simplified Analogues, Concordia Lo
Theses and Dissertations
The first project in this dissertation describes the use of microwave-promoted iminyl radical fragmentations to form functionalized nitriles. Nitrogen-centered radical chemistry is a useful tool to construct valuable C-N bonds commonly found in pharmaceuticals and biologically active molecules. Classically, these reactions require the use of toxic initiators and propagators. Iminyl radical chemistry has been gaining momentum as a means of avoiding these harsh conditions. This project utilizes the fragmentation of cyclic iminyl radicals via irradiation of O-phenyl oxime ethers to produce a synthetically useful nitrile tethered to an alkyl radical in the absence of metal catalysts and redox chemistry. The …
Quantitative Stem: A Method For Measuring Temperature And Thickness Effects On Thermal Diffuse Scattering Using Stem/Eels, And For Testing Electron Scattering Models, Paul S. Minson
Theses and Dissertations
In the last two decades, advances in the dark field detectors and microscopes of scanning transmission electron microscopy (STEM) have inspired a resurgence of interest in quantitative STEM analysis. One promising avenue is the use of STEM as a nanothermometric probe. In this application, thermal diffuse scattering, captured by a CCD camera or an annular dark field detector, acts as an indirect measurement of the specimen temperature. One challenge with taking such a measurement is achieving adequate sensitivity to quantify a change in scattered electron signal on the order of 1% or less of the full electron beam. Another difficulty …

Cyanobacteria And Phytoplankton Responses To Nutrients In Deep-Water Montane Reservoirs, Madeleine Paige Malmfeldt
Cyanobacteria And Phytoplankton Responses To Nutrients In Deep-Water Montane Reservoirs, Madeleine Paige Malmfeldt
Theses and Dissertations
Mountains play an important role in providing water resources from snow and ice to downstream urban population centers. In Utah, USA, nearly 86% of the state's population resides in the rapidly growing urban corridor along the Wasatch Front. Water along the Wasatch Front is stored in several deep reservoirs in the Provo River Watershed. Additions of nutrients, into these reservoirs, may stimulate the growth of primary producers (e.g., total phytoplankton and cyanobacteria) potentially attenuating water quality. To determine the influence of nutrients on primary producers in the Provo River's reservoirs, identify whether cyanobacteria are transported downstream, and quantify nutrient thresholds …
Non-Linear Optical Characterization Of Stressed Materials, Kaylee N. Rellaford
Non-Linear Optical Characterization Of Stressed Materials, Kaylee N. Rellaford
Theses and Dissertations
Interactions between materials, their surfaces, and applied stresses are involved in every man-made construction in the world. Therefore, finding ways to interact without altering inherent properties of materials is of great interest. Surface spectroscopies, including second harmonic generation (SHG) and sum frequency generation (SFG), are inherently noninvasive testing methods. Both SHG and SFG are well-developed techniques that can be used in various applications including the characterization of material state. Both of these techniques allow for a noninvasive analysis of various materials, such as metals and polymers. We have used SHG as a method to characterize the change in signal strength …
Understanding Factors Influencing Seed Germination Of Seven Wildflowers In Sub-Alpine Ecosystems, Alyssa Joy Brown
Understanding Factors Influencing Seed Germination Of Seven Wildflowers In Sub-Alpine Ecosystems, Alyssa Joy Brown
Theses and Dissertations
This thesis explores the seed germination of seven wildflowers native to sub-alpine ecosystems. Wildflowers are an essential functional group in native plant ecosystems. Also known as forbs, these plants offer a myriad of benefits in addition to being aesthetically pleasing. They provide habitats for anthropods and small mammals, support native pollinator populations, and grow well with other plant functional groups (especially perennial grasses and shrubs). Healthy plant communities make use of the limited resources in our native ecosystems, competing with invasive species that can otherwise dominate the landscape. Germination involves the transition from seed to an actively growing plant. Following …

The Rusty Butler Archive: Revelations Of Cultural Repression During The Brazilian Military Dictatorship, Calla J. C. Knapp
The Rusty Butler Archive: Revelations Of Cultural Repression During The Brazilian Military Dictatorship, Calla J. C. Knapp
Theses and Dissertations
The twenty-one years of military dictatorship in Brazil were marked by severe repression as government censors controlled every aspect of the media and artistic production. During these tense years from 1964 to 1985, many journalists, academics, writers, and artists struggled to voice their opposition to oppressive military control. In this same period, many playwrights turned to protest theater as a way to speak out against the dictatorship's abuses. Unsurprisingly, some of the plays produced at this time were heavily censored or shut down. In the late 1960s and early 1970s, a young Brazilianist scholar, Ross "Rusty" Butler, befriended, interviewed, and …
Investigating The Influence Of Available Drinking Water On Wildlife In Utah's West Desert, Danielle K. Finlayson
Investigating The Influence Of Available Drinking Water On Wildlife In Utah's West Desert, Danielle K. Finlayson
Theses and Dissertations
The availability of water is a limiting resource for many wildlife species in arid and semi- arid environments. Free water is essential for critical life stages for numerous species, including migration, reproduction, survival, and habitat selection. Riparian areas in the desert occur relatively infrequently, but support a disproportionally large percentage of plant and wildlife species found in arid environments. Our study covered two aspects of water use in the west desert of Utah. The first was assessing the impacts of nonnative ungulates (specifically feral horses and cattle) on natural springs, and how they influenced water quality, vegetation, and wildlife diversity …
Development And Evaluation Of An Improved Microbial Inactivation Model For Analyzing Continuous Flow Uv-Led Air Treatment Systems, Cole Holtom Thatcher
Development And Evaluation Of An Improved Microbial Inactivation Model For Analyzing Continuous Flow Uv-Led Air Treatment Systems, Cole Holtom Thatcher
Theses and Dissertations
This thesis discusses the development of an improved microbial inactivation model for analyzing continuous flow UV-LED air treatment systems and use of the model to evaluate the impact of several treatment system design parameters on inactivation. Model development includes three submodels: a radiation submodel, a fluid flow submodel, and an inactivation kinetics submodel. Radiation modeling defines the UV irradiance throughout the system. Fluid flow modeling provides the residence times that microbes spend exposed to the UV irradiation while passing through the system. Inactivation modeling combines irradiance and residence times with inactivation kinetics to calculate species-specific inactivation in a treatment system. …
