Optimization Of In-Vessel Food Waste Composting: Enzyme Activity And Microbial Dynamics, Ayawovi Selom Ametepe

Graduate Theses and Dissertations

A series of greenhouse-based, rotary-drum bioreactor experiments was designed to study microbial dynamics and enzyme activity during optimization of food waste composting. This work aims to optimize food waste composting by defining the best food waste-to-bulking agent proportion controlling conditions and by evaluating the food waste composting process when inoculated by a bacterial inoculant product compared to uninoculated compost. Three experiments were run in total. The two first experiments were conducted for 48 days with sampling at each step of composting, while the third experiment last 50 days and included one extra sampling date. In the first experiment, 50:50, 65:35 …

Polerovirus Genomic Variation And Mechanisms Of Silencing Suppression By P0 Protein, Natalie M. Holste

School of Biological Sciences: Dissertations, Theses, and Student Research

The family Luteoviridae consists of three genera: Luteovirus, Enamovirus, and Polerovirus. The genus Polerovirus contains 32 virus species. All are transmitted by aphids and can infect a wide variety of crops from cereals and wheat to cucurbits and peppers. However, little is known about how this wide range of hosts and vectors developed. In poleroviruses, aphid transmission and virion formation is mediated by the coat protein read-through domain (CPRT) while silencing suppression and phloem limitation is mediated by Protein 0 (P0)—a protein unique to poleroviruses. P0 gives poleroviruses a great advantage amongst plant viruses and diversifies polerovirus species, but the …

A Path To Data-Driven Health Care Enforcement, Jacob T. Elberg

Utah Law Review

The Department of Justice (“DOJ”) has a long-stated goal of encouraging companies to engage in what the author refers to as “compliant behaviors”—maintenance of an effective pre-existing compliance program, post-enforcement adoption of an effective compliance program, cooperation with a government investigation, and self-disclosure of misconduct. Substantial DOJ guidance over the past two decades, along with the concrete incentive structure of the United States Sentencing Guidelines, have increasingly made clear to organizations when and how such behaviors will be rewarded in criminal matters. Recently, DOJ has made transparency and clarity regarding the benefit of compliant behaviors a priority in calculating and …

Zoning Cyberspace: Protecting Privacy In The Digital Upside Down, Raymond H. Brescia

Utah Law Review

Over fifty years ago, Charles Reich posited that we should extend property protections to what he would call “government largess”: that array of interests—from licenses to welfare benefits—that often form the bases for one’s economic existence in the modern world. Reich considered such protections essential to the preservation of individual autonomy, the independence that is critical to a functioning democracy. Today, our most personal information and even our thoughts, as reflected in our online activities and digital existence, are subject to “private largess.” Private entities possess information central to the identity of those individuals who utilize their services. This information …

Regulatory Challenges For Treating Failure To Disclose Fcoi As Research Misconduct In Public Health Research, Tammy M. Frisby

Utah Law Review

It is unlikely that a court would find that current HHS regulations provide legal authority for PHS funding-agencies to address “serious noncompliance” with FCOI disclosure requirements as research misconduct. With one exception—the culpability standard for research misconduct—the administrative law governing bias and integrity in PHS-funded research does not support treating even the most serious cases of failure to disclose FCOI in itself as research misconduct in violation of PHS regulations. Indeed, there are at least four features of that law which would support a claim that an HHS action to treat FCOI nondisclosure as research misconduct was “arbitrary and capricious.” …

Embedding Metaliteracy In The Design Of A Post-Truth Mooc: Building Communities Of Trust, Thomas P. Mackey

Communications in Information Literacy

Metaliteracy is examined as a comprehensive framework to develop learners as informed consumers and active producers of information in collaborative communities of trust. In today's post-truth society, personal and political beliefs have often diminished the meaning and impact of truth and objective reasoning. Metaliteracy prepares reflective learners to responsibly consume and ethically produce information in participatory social environments. As civic-minded citizens, metaliterate learners take control of their learning while mindfully participating in cooperative and productive communities. The innovative Massive Open Online Course (MOOC), Empowering Yourself in a Post-Truth World, is analyzed as part of this pedagogical strategy to prepare …

Punishing Pill Mill Doctors: Sentencing Disparities In The Opioid Epidemic, Adam M. Gershowitz

Faculty Publications

Consider two pill mill doctors who flooded the streets with oxycodone and other dangerous opioids. The evidence against both doctors was overwhelming. They each sold millions of opioid pills. Both doctors charged addicted patients hundreds of dollars in cash for office visits that involved no physical examinations and no diagnostic tests. Instead, the doctors simply handed the patients opioids in exchange for cash. To maximize their income, both doctors conspired with street dealers to import fake patients — many of them homeless — so that the doctors could write even more prescriptions. Both doctors made millions of dollars profiting off …

The Resilience Of Female Survivors Of Intimate Partner Violence In Southwest Nigeria: An Interdisciplinary Analysis, Tobi F. Oloyede

Electronic Theses and Dissertations

Female survivors of intimate partner violence (IPV) in Nigeria endure harsh and traumatic experiences that affect their rights as women and their well-being. As the phenomenon of IPV persists in Nigeria, it is not only a family problem but a critical social and psychological problem. This study examined Nigerian female survivors’ hidden strength, agency, and resilience, rather than their powerlessness and vulnerability.

Longitudinally Extensive Transverse Myelitis: A Sub-Saharan Conundrum, Antonina Obayo, Sylvia Mbugua, Sayed Karar

Internal Medicine, East Africa

Spinal cord schistosomiasis is a rare, underdiagnosed manifestation of schistosomiasis. We present the case of a 36-year-old male who presented to our institution with a one-week history of low back pain with rapidly progressive lower limb weakness, loss of sensation, and flaccid paraparesis. An MRI of the spine showed a longitudinally extensive transverse myelitis from T6 to L1, with enhancement at the cauda equina region. Further review of the images and serological tests eventually led to diagnosis of spinal schistosomiasis. He was treated with praziquantel and high-dose steroids, with minimal improvement in his symptoms.

Water-Soluble Polymers With Ceramic/Metal Nanoparticles For Use As Anode Materials In Lithium-Ion And Sodium-Ion Batteries, Roberto Orrostieta Chavez

Theses and Dissertations

Aqueous solutions of poly(vinylpyrrolidone) (PVP) with 20, 25, and 28 wt.% concentrations were successfully spun into fibers by centrifugal spinning. The pristine PVP fibers were annealed and carbonized to produce flexible carbon fibers for use as binder-free anodes in lithium-ion and sodium-ion batteries. These flexible carbon fibers were prepared by developing a novel three-step heat treatment to reduce the residual stresses in the pristine PVP precursor fibers and to prevent fiber degradation during carbonization. The average diameters of the pristine, annealed, and carbonized fibers were obtained using scanning electron microscopy (SEM), which showed that the average diameter of the carbon …

Department of Medical Oncology Faculty Papers

Uveal melanoma is a rare and aggressive malignancy and up to half of all patients will develop metastatic disease despite the effective treatment of the primary tumor. Insulin-like growth factors I/II play a fundamental role in the cell migration, proliferation, and apoptosis. IMC-A12, a mAb specifically targets insulin-like growth factor type I receptor, has shown promise in preclinical studies. We performed a multicenter phase II study for patients with metastatic uveal melanoma administered IMC-A12 10 mg/kg IV every two weeks until disease progression or unacceptable toxicity. The primary endpoint was objective response (proportion of patients with complete or partial response), …

Development Of A Self-Powered Weigh-In-Motion System, Athanassios Papagiannakis, Sarah Ahmed, Samer Dessouky, Reza Khalili, Gopal Vishwakarma

Publications

This report describes the development of a novel weigh-in-motion (WIM) system that utilizes piezoelectric elements for sensing load and powering an ultra-low power microcontroller unit (MCU) that serves as its data acquisition system. A system of 4 piezoelectric (PZT) stacks serves as the energy harvester, while load sensing is done via a set of 4 PZT elements connected in parallel. Two alternative MCUs were considered, with various data handling capabilities and power consumption requirements. These MCUs have very short “wake-up” times allowing vehicle sensing without the need for inductive loops commonly used in conventional WIM systems. Special electric circuits were …

Climate Change Is Likely To Increase The Development Rate Of Anthelmintic Resistance In Equine Cyathostomins In New Zealand, Christian W. Sauermann, Dave M. Leathwick, Mark Lieffering, Martin K. Nielsen

Maxwell H. Gluck Equine Research Center Faculty Publications

Climate change is likely to influence livestock production by increasing the prevalence of diseases, including parasites. The traditional practice of controlling nematodes in livestock by the application of anthelmintics is, however, increasingly compromised by the development of resistance to these drugs in parasite populations. This study used a previously developed simulation model of the entire equine cyathostomin lifecycle to investigate the effect a changing climate would have on the development of anthelmintic resistance. Climate data from six General Circulation Models based on four different Representative Concentration Pathways was available for three New Zealand locations. These projections were used to estimate …

Sex Differences In Fatigability Following Exercise Normalised To The Power–Duration Relationship, Paul Ansdell, Jacob Skarabot, Elliott Atkinson, Sarah Corden, Amber Tygart, Kristy M. Hicks, Kevin Thomas, Sandra K. Hunter, Glyn Howatson, Stuart Goodall

Exercise Science Faculty Research and Publications

Due to morphological differences, females demonstrate greater fatigue resistance of locomotor muscle during single-limb and whole-body exercise modalities. Whilst females sustain a greater relative intensity of single-limb, isometric exercise than males, limited investigation has been performed during whole-body exercise. Accordingly, this study established the power–duration relationship during cycling in 18 trained participants (eight females). Subsequently, constant-load exercise was performed at critical power (CP)-matched intensities within the heavy and severe domains, with the mechanisms of fatigability assessed via non-invasive neurostimulation, near-infrared spectroscopy and pulmonary gas exchange during and following exercise. Relative CP (72 ± 5 vs. 74 ± 2% P …

The Case Of Limbo: The Search For Identity In Sylvia Plath’S Short Fiction And The Bell Jar, Kristin Lyons

Undergraduate Honors Theses

Though Sylvia Plath’s poems and novel undergo frequent scholarly research, her short fiction is often overlooked. Plath’s journals influenced her short fiction writing, and her stories reflected Plath’s lived experiences. Plath’s short fiction, like her other works, explore themes of identity and detachment. Each of her protagonists exist in a personal limbo, and they strive to find their identities and to fit the roles in which they occupy. This thesis focuses on “Mary Ventura and the Ninth Kingdom,” stories from Johnny Panic and the Bible of Dreams, and additional research from scholarly journals and biographies, with comparisons to identity struggles …

Technology Aiding In Neonatal Lung Developmental Care, Megan Kirk

Undergraduate Honors Theses

In this paper, old as well as new technological findings to decrease premature infant mortality are reviewed. This paper discusses fetal development throughout pregnancy from conception to full-term status as well as fetal lung development specifically from conception until full-term status. Several ideas to rapidly develop and mature fetal lungs are discussed such as mothers ingesting artificial surfactant supplements, either independently or coupled with antenatal corticosteroids, as well as intra-amniotic instillation prior to 28 weeks gestational. Drawbacks regarding these two are mentioned as well such as the fetus’s lungs not being mature enough to use the artificial surfactant leading into …
