Interferon-Γ Medaites Lung Damage Through The Hyper-Activation Of Ccr2+ Inflammatory Monocytes During Influenza Virus Infection, Mitchell Anthony Klomp

Theses and Dissertations

Influenza viruses (IV) have caused untold morbidity and mortality throughout the previous centuries. These viruses have caused several pandemics that have witnessed the loss of millions of lives. Today, IVs continue to circulate annually, and the efficacy of influenza virus vaccines are limited. As IV pandemics in 1918, 1957, and 2009 have shown the world, the push for a universal influenza vaccine has never been more relevant. While much research has been devoted to understanding the virology around IVs, the immunopathology of the host-pathogen axis has been less studied. Recently, there has been much attention on the role of the …

Contribution Of Intestinal Dysfunction To Alzheimer’S Disease Progression, Mona Sohrabi Thompson

Theses and Dissertations

Longer life expectancies, due to advanced medical care, social, and environmental conditions, helped increase the number and percentage of Americans aging to ≥85. The number of individuals with Alzheimer’s disease (AD) age 65 or older is projected to be 7.1 and 13.8 million by 2025 and 2050, respectively. The total annual health care expense for AD patients is estimated to increase from $290 billion in 2019 to more than $1.1 trillion in 2050 (Association, 2019). Conclusively, AD is expected to become a more common cause of death and a major public health predicament due to aging of the baby boom …

At-Home Childcare Providers’ Perceptions Of Gardening With Children, Erin Lauckner

Theses and Dissertations

Children do not consume recommended amounts of fruits and vegetables, which has been correlated with negative health consequences. Gardening with children has been shown to positively impact children’s consumption of these foods. While research investigating gardening with children exists, much of this has been conducted with teachers and children in schools, and limited research has been conducted with childcare providers and preschool-aged children. Little research has been conducted about this topic with in-home childcare providers and the children under their care. This pilot study utilized a cross-sectional mixed methods research design through an online survey instrument. A convenience sample of …

Electron Beam Irradiation As A Potential Lipid Decontamination Technique For Life Detection Instruments, Denise Kathleen Buckner

Theses and Dissertations

In the search for extraterrestrial life, identification of molecular biosignatures is a key technique. Lipids are important molecular biosignatures: they are ubiquitous to terrestrial life, survive for billions of years in the geologic record, can form biotically and abiotically (bearing molecular features indicating biogenicity), and are detected throughout the Solar System. Lipid-based life detection instruments require stringent contamination control to prevent false positives, but traditional decontamination techniques are unlikely to sufficiently remove lipid contamination without compromising instrument materials. This thesis investigates Electron Beam Irradiation (EBI) as a potential decontamination technique; five representative lipid standards, including palmitic acid, oleic acid, heneicosane, …

Automated Fractional Snow Cover Monitoring From Near-Surface Remote Sensing In Grassland, Anai Caparo Bellido

Theses and Dissertations

Snow cover is an important variable in both climatological and hydrological studies because of its relationship to environmental energy and mass flux. However, variability in snow cover can confound satellite-based efforts to monitor vegetation phenology.

This research explores the utility of the PhenoCam network cameras to estimate Fractional Snow Cover (FSC) in grassland. The goal is to operationalize FSC estimates from PhenoCams to inform and improve satellite-based determination of phenological metrics.

The study site is the Oakville Prairie Biological Field Station, located near Grand Forks, North Dakota. I developed a mostly semi-automated process to estimate FSC from PhenoCam images through …

The Impact Of Clinician Attachment Style On Burnout And Job Satisfaction: Introducing Mindfulness As A Mediator, Jill Marie Calderon

Theses and Dissertations

Attachment style is theorized to develop in childhood, as a result of the bonds that develop between child and caregiver. The research has shown individuals with an insecure attachment style are more at risk for job burnout and less satisfied with their jobs. This study proposed, mindfulness may be the internal process influencing the relationship between attachment style, burnout and job satisfaction. Mindfulness is defined as paying attention on purpose, in the present moment, nonjudgmentally and has found to be positively correlated with secure attachment styles. Additionally, mindfulness has shown to have a negative relationship with burnout and a positive …

Influences On The Development Of Ethical Decision-Making In Speech-Language Pathology Students: A Phenomenological Study Of Graduate Students And Clinical Supervisors, Joni K. Mehrhoff

Yet, limited research is available to define the development of student ethical decision-making. The purpose of this study was to explore what influences SLP graduate students and clinical supervisors ascribe to in the development of ethical decision-making. Participants included five SLP graduate students and six SLP clinical supervisors from accredited …

Physical Activity And Depression In Mothers Of A Child With A Special Health Care Need: Informing Future Interventions, Brianna Jean Black

Theses and Dissertations

In the United States, approximately 20 percent of all children have a special health care need. Additionally, mothers of a child with a special health care need have worse overall well-being, mental and physical health compared to mothers of typically developing children. Physical activity may improve depressive symptoms and overall health in these mothers; however, little is known about the acceptability of physical activity interventions for mothers of a child with a special health care need. Therefore, the primary aim of this study was to understand more about mother’s desire to use physical activity to improve depressive symptoms after having …

A Study Of The Feasibility Of Growth, Extraction, And Industrial Scale Up Processing Of Microalgae Lipids., Jasmine Oleksik

Theses and Dissertations

The interest in microalgae as a plausible alternative to crop oils as a raw material in the form of triglycerides and free fatty acids (FA oils) for renewable fuels and chemicals is increasing and it is a widespread research topic at the lab scale. Microalgae contain a higher lipid content on a dry weight basis compared to oilseeds such as soybeans. Additionally, the growth and cultivation cycle of microalgae is 15 days, in comparison to soybeans where the cycle occurs once or twice annually. Despite these advantages, to date it has been uneconomical to produce microalgae oils in a world-scale …

Bio-Regenerative Life Support Systems Functional Stability And Limitations, A Theoretical Modeling Approach, Curt I. Holmer

Mapping Land Use And Land Cover Change And Its Impact On Landscape Structure And Amphibian Functional Connectivity In The Prairie Pothole Region, Taylor Holm

Theses and Dissertations

Monitoring land use and land cover (LULC) change and its effect on habitat availability and connectivity is crucial for species conservation and management. This is most efficiently accomplished at a sufficiently broad scale using remote sensing technology. Current approaches benefit from freely available data sources such as National Land Cover Database (NLCD), derived from 30 m Landsat imagery. However, temporal frequency and spatial resolution of NLCD may be insufficient for some applications. Specifically, 30 m resolution data may not detect small or narrow landscape features that may be important habitat for small animals such as amphibians. Other available data sources, …

Mountain Lions In North Dakota: A Public Opinion Survey, Theodore A. Darnell

Theses and Dissertations

Breeding mountain lion (Puma concolor) populations currently inhabit the western portion of North Dakota. In recent years, apparent increases in human-lion interactions across North Dakota, and other Midwest states, have challenged wildlife managers who strive to balance biological and social carrying capacities of these animals. In 2019, we surveyed 2,000 residents of North Dakota, USA, using a self-administered mail survey to discern knowledge of and attitudes towards mountain lions, and to explore whether the presence of these animals would influence decisions to recreate in western North Dakota. Our questionnaire included 12 questions designed to ascertain respondent attitudes towards mountain lions. …

Optimization Of Electrospray Ionization For Liquid Chromatography Time-Of-Flight Mass Spectrometry Analysis Of Preservatives In Wood Leachate Matrix, Kukowski Klara, Gysbers Brianna, Stephen Fisher, Alena Kubatova

Chemistry Faculty Publications

Triazoles and 3-iodo-2-propynyl butylcarbamate (IPBC) are commonly used wood preservatives active against a wide range of fungi and bacteria. As they are prone to leaching, their amounts need to be monitored by the industry to determine preservative loss from the products and for environmental impact assessment. Therefore, a liquid chromatography–electrospray–time-of-flight mass spectrometry (LC–ESI–TOFMS) method was developed and optimized for simultaneous quantification of triazoles and IPBC in aqueous wood extracts, specifically wood leachate. Analyte pre-concentration on a solid-phase extraction cartridge prior to the analysis yielded > 94% recoveries. ESI method parameters (e.g., solvent system, electrolyte type, electrolyte concentration, capillary and fragmentor voltages) …

Barefoot Running: Effects On Emg Activity Of Gluteus Medius And Tensor Fascia Latae In Habitually Shod Runners, Bailey Neubauer, Zach Drevlow, Alexandra Gerlach

Physical Therapy Scholarly Projects

Purpose/Hypothesis: Running has been a common practice in humans since the species’ dawn. Due to its relative ease and low cost, running continues to be one of the most popular forms of exercise today. Although running provides many benefits such as disease prevention, injury prevalence in running is high. The trend of minimalist shoes and barefoot training has gained popularity over the decade as a return to a more natural form of running. Some researchers hypothesize that barefoot running can reduce injury rate by changing the biomechanics of the runner. In this study we propose a different hypothesis: barefoot running …

Red Oak Seedlings As Indicators Of Deer Browse Pressure: Gauging The Outcome Of Different White-Tailed Deer Management Approaches, Bernd Blossey, Paul Curtis, Jason Boulanger, Andrea Davalos

Biology Faculty Publications

After decades of high deer populations, North American forests have lost much of their previous biodiversity. Any landscape‐level recovery requires substantial reduc‐ tions in deer herds, but modern societies and wildlife management agencies appear unable to devise appropriate solutions to this chronic ecological and human health crisis. We evaluated the effectiveness of fertility control and hunting in reducing deer impacts at Cornell University. We estimated spring deer populations and planted Quercus rubra seedlings to assess deer browse pressure, rodent attack, and other factors compromising seedling performance. Oak seedlings protected in cages grew well, but deer annually browsed ≥60% of unprotected …
