Characterization Of Bacteriophage Targeting Bacillus Licheniformis In Milk Processes And Thermal Stability Of Bacteriophage During Htst Pasteurization, Jeremy Robert Arbon Dec 2021

Characterization Of Bacteriophage Targeting Bacillus Licheniformis In Milk Processes And Thermal Stability Of Bacteriophage During Htst Pasteurization, Jeremy Robert Arbon

Theses and Dissertations

An array of Bacillus licheniformis strains were isolated from a commercial powdered milk process. Bacteriophages exhibiting activity against B. licheniformis were isolated from cattle manure and effluent samples destined for a lagoon at a dairy farm. After sequencing, 8 of the 10 phages were found to be novel and genetically differentiated. Transmission electron scanning microscopy (TSEM) was performed. All bacteriophages were of the family Herelleviridae with contractile tail sheaths ranging from 80µm to 150µm and, surprisingly, survived a common fluid milk processing treatment used to inactivate vegetative cells. The survival of the phage after high temperature short time pasteurization of …


Whooping Crane (Grus Americana) Family Consumes A Diversity Of Aquatic Vertebrates During Fall Migration Stopover At The Platte River, Nebraska, Andrew J. Caven, Keith D. Koupal, David M. Baasch, Emma M. Brinley Buckley, Jenna Malzahn, Michael L. Forsberg, Mariah Lundgren Dec 2021

Whooping Crane (Grus Americana) Family Consumes A Diversity Of Aquatic Vertebrates During Fall Migration Stopover At The Platte River, Nebraska, Andrew J. Caven, Keith D. Koupal, David M. Baasch, Emma M. Brinley Buckley, Jenna Malzahn, Michael L. Forsberg, Mariah Lundgren

Western North American Naturalist

The Aransas-Wood Buffalo population of Whooping Cranes (Grus americana) migrates approximately 4000 km through the central Great Plains biannually, between their breeding and wintering grounds. Whooping Cranes depend on stopover sites to provide secure resting locations and the caloric resources necessary to complete their migration, such as the USFWS-designated critical habitat area in the Central Platte River Valley (CPRV) of Nebraska. This area includes braided river habitat characterized by low-elevation and submerged sandbars, which provide important roosting and foraging opportunities for migrating Whooping Cranes. We used long-range photography, videography, and behavioral scan sampling to document forage items consumed …

Atypical Sensory Processing And Semantic Language In Autistic Children, Charlene L. Cooper Dec 2021

Atypical Sensory Processing And Semantic Language In Autistic Children, Charlene L. Cooper

Theses and Dissertations

Autistic children demonstrate a constellation of traits with varying degrees of severity in areas including language differences, restrictive and repetitive behaviors, and sensory processing differences. However, the relationship between sensory processing and these other behaviors are not well understood especially their neurobiological underpinnings. Therefore, this research examined behavioral measures of semantic language, sensory traits, and associated brain networks in 20 autistic children (ages 6-11) and 22 typically developing (TD) age matched peers. Mann-Whitney U tests revealed a strong correlation between sensory traits and general composite and semantic language in both groups of participants. Sensory seeking traits were most significantly correlated …

The Impact Of Inkjet Parameters And Environmental Conditions In Binder Jetting Additive Manufacturing, Trenton Miles Colton Dec 2021

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 Dec 2021

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 …


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 Dec 2021

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 …


Microwave-Promoted Iminyl Radical Fragmentations And The Total Synthesis Of Yaku'amide A And Its Simplified Analogues, Concordia Lo Dec 2021

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 …


Field Investigations And Numerical Modeling Of Earthquake And Tsunami Risk At Four Vulnerable Sites In Indonesia, Claire E. Ashcraft Dec 2021

Field Investigations And Numerical Modeling Of Earthquake And Tsunami Risk At Four Vulnerable Sites In Indonesia, Claire E. Ashcraft

Theses and Dissertations

Maps and models of seismic and tsunami risk are constructed from a variety of measurements taken in Indonesia, which have the potential to reduce loss of life and infrastructure. The first study uses the multichannel analysis of surface waves (MASW) method to calculate the time-averaged shear wave velocity to 30 m depth (Vs30). These measurements were taken at 58 sites in the city of Pacitan, Java and on the islands of Lombok, Ambon, and the Banda Islands. Vs30 calculations are compared with local geologic maps to extrapolate site class for locations not measured directly. Site class maps are then compared …

Cyanobacteria And Phytoplankton Responses To Nutrients In Deep-Water Montane Reservoirs, Madeleine Paige Malmfeldt Dec 2021

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 …


Understanding Factors Influencing Seed Germination Of Seven Wildflowers In Sub-Alpine Ecosystems, Alyssa Joy Brown Dec 2021

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 Dec 2021

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 …


Development And Evaluation Of An Improved Microbial Inactivation Model For Analyzing Continuous Flow Uv-Led Air Treatment Systems, Cole Holtom Thatcher Dec 2021

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. …

Identifying Sinorhizobium Meliloti Genes That Determine Fitness Outcomes, Alexander B. Benedict Dec 2021

Identifying Sinorhizobium Meliloti Genes That Determine Fitness Outcomes, Alexander B. Benedict

Theses and Dissertations

The remarkable metabolic capacity of the soil-dwelling bacterium Sinorhizobium meliloti is encoded on its three circular replicons: the chromosome and two large megaplasmids, pSymA and pSymB. Despite making up 45% of the genome, the pSymA and pSymB megaplasmids can be cured from S. meliloti. This unique attribute provides an opportunity to study the essentiality of chromosomal genes in the presence or absence of nearly half the genome. By interrogating chromosomal genes via massively parallel transposon insertion sequencing (Tn-seq) in the presence and absence of pSymA and pSymB, we identified 307 genes as being essential for viability regardless of the genomic …


Witnessing "Story Truth" And The Narrative Of The Resurrection: Reintegration After Crisis In Tim O'Brien's The Things They Carried, Hayley E. Langton Dec 2021

Witnessing "Story Truth" And The Narrative Of The Resurrection: Reintegration After Crisis In Tim O'Brien's The Things They Carried, Hayley E. Langton

Theses and Dissertations

Sarah Bachelard describes crisis as a turning point during which all previous frameworks collapse. The narrative structure of the resurrection reveals the influential role of narrative in reintegrating such crises back into a place of meaning and wholeness. Using the resurrection narrative as an interpretive framework for Tim O'Brien's The Things They Carried reveals how "story truth" acknowledges the transcendent meaning that lies beyond all texts and circumstances, and so reintegrates crisis and redeems meaning for Tim and his fellow soldiers. The transcendent and transformative qualities of story truth illustrate the latter's innately spiritual nature, even within secular texts. Story …
