Glacial Lake Reflectance As A Proxy For Changing Glacial Conditions And Impacts On Streamflow, Lance Diangelis

Theses and Dissertations

Climate change continues to manifest itself through increased temperatures across the Western United States. Subsequently glaciers in the Wind River Range of Wyoming have been in decline since the end of the Little Ice Age and continue to lose mass during the annual ablation season. Understanding these changes is of paramount importance for water resource managers. This study uses data from Landsat 5, 7 and 8 over a 33-year period from 1984-2017 to determine the long-term change in water color for lakes in the range related to glacial flour discharge. Water color can be used to indicate changes in the …

Effect Of Cisplatin On Metallothionein Expression In Urotsa Cells Malignantly Transformed With Arsenite Or Cadmium, Brooke Alexandra Freeberg

Theses and Dissertations

Heavy metals Arsenite (As3+) and Cadmium (Cd2+) are known human carcinogens and exposure to them occurs through cigarette smoking, industrialization, and contaminated water sources. Epidemiological studies have shown that prolonged exposure to these heavy metals are associated with several health issues, including bladder cancer. With survival rates directly correlated to detection age and tumor stage, the demand for early detection would effectively cut costs and improve the patient prognosis of human bladder cancer.

Metallothioneins (MT) play an essential role in metal regulation, heavy metal detoxification, and cellular redox chemistry in cellular biological systems and tissues. Previous studies in literature have …

Modeling Threats To Honey Bees In North Dakota From Land-Use Change And Pesticide Applications, Daniel Dixon

This thesis explored landscape scale pesticide use trends from both spray applied and seed treated insecticides on lands within 1.6km of ~13,000 registered apiaries North Dakota from 2001 to 2015. The regional application of five spray applied insecticides was collectively modeled using InVEST’s Habitat Quality Model during years of heightened land-use change. In these models, regional application rates were converted …

The Impact Of Implicit Attitudes On Behavioral Intentions To Prevent Suicide, Julio Brionez

Theses and Dissertations

The suicide rate in the United States of America continues to climb despite national strategies to reduce it (Centers for Disease Control and Prevention & National Center for Health Statistics, 2016; U.S. Department of Health and Human Services (HHS) Office of the Surgeon General & National Action Alliance for Suicide Prevention, 2012). What the strategies lack is mechanisms to target implicit attitudes (IAs) about suicide. This omission is important as IAs have been effective at predicting future suicide attempts (Nock et al., 2010). This study used an implicit association test of attitudes to suicide (IAT-SUICIDE) to examine IAs to suicide …

Wild And Domestic: Short Stories, Sara E. Dupree

Theses and Dissertations

Wild and Domestic is a collection of short stories set in rural northwestern Minnesota that center around themes of parenting, family, and the desire for stability and security. This desire for domestic harmony often comes into conflict with the characters’ strong desire for personal freedom, self-expression, sexual gratification, and a deeper connection to the natural world—desires that are linked to the concept of wild. The collection also invites readers to reflect on its animal characters. In many of the stories, animal characters, both wild and domestic, play a role in setting up the crisis or climax of the story by …

Faculty And Staff Perceptions About Concealed Carry Initiatives And Their Effect On Campus Safety: A Multi-State Examination, Heidi Marie Ahl-Quanbeck

Theses and Dissertations

Concealed carry on campus is a polarizing debate affecting higher education today. Concealed carry refers to the carrying of a weapon in public while concealed from view. Prompted by isolated instances of gun violence as well as the changing gun culture within our society, ten states now permit weapons on campus as a result of legislation or institutional policy. Yet, little is known about faculty and staff perspectives on concealed carry on campus initiatives or how weapons could affect perceptions about campus safety. The purpose of this study is to better understand faculty and staff perspectives on concealed carry, to …

Juror Perceptions Of Child Witness Testimonial Aids, Rachael Sophia Mickelson Hendrickson

Theses and Dissertations

The goal of the present study is to assess the affect testimonial supports have on mock jurors’ perceptions of child witnesses in a sexual abuse case. In general jurors’ perceptions operate on a two-factor model. The two factors are child competency and honesty. Jurors perceive children’s competency and honesty differently based on the child’s age and the mock juror’s gender. Testimonial supports have been suggested as a way to relieve some of the stress that a trial brings on a child. However, this seems to exacerbate the negative perceptions jurors already hold of child witnesses. The current juror perceptions of …

Mitigating Environmental Impacts Of Terminal Lake Flooding: A Case Study Of Devils Lake, North Dakota, Afshin Shabani

Theses and Dissertations

Devils Lake is an endorheic lake in the Red River of the North basin in northeastern North Dakota. During the last two decades, the lake water level has risen by nearly 10 m, causing floods that have cost more than 1 billion USD in mitigation measures. Another increase of approximately 3.0 m in the lake water level would cause spillage into the Sheyenne River. To alleviate this potentially catastrophic spillage, two artificial outlets were constructed. However, the artificial drainage of water into the Sheyenne River raises water quality concerns because the Devils Lake water contains significantly higher concentrations of dissolved …

Using Thermal Imaging To Characterize Groundwater Seepage In A North Dakota Fen, Ogochukwu Ozotta

Theses and Dissertations

Groundwater flow and its dissolved mineral transport plays a fundamental role in the ecology of many wetlands. Installation of equipment to map groundwater seepage, however, is invasive and may damage vegetation and potentially affect biodiversity. By mapping surface temperature remotely in the late summer, when the differential between warm soil and cold groundwater is the greatest, the temperature patterns may reveal areas of greatest upward gradient and flow.

To test the hypothesis, the effect that hydraulic gradient has on surface temperature in a fen located at the north end of the Cherry Lake Aquifer, Eddy County, ND (47.73, -98.66) was …

The Involvement Of Polyol Pathway In Hypgerglycemia And Cadmium Toxicity In The Establishment Of Diabetic Neprhopathy, Bethany Anne Davis

Theses and Dissertations

Diabetic nephropathy (DN) is a major cause of end-stage renal disease (ESRD), where prolonged exposure to hyperglycemia induces damage to proximal tubule cells of the kidney. Since progression to ESRD correlates to pathological changes in the tubular segments of the kidney, the effects of hyperglycemia in the PT portion of the nephron may be particularly relevant to the progression of DN. Development of this disease also is likely to occur in the context of exposure to other renal toxins, and the heavy metal cadmium (Cd2+) may be the most relevant due to the accumulation of this metal in the major …

Bystander Self-Efficacy To Prevent Sexual Assault: An Evaluation Of The Impacts Of Online And In-Person Bystander Intervention Training, Morgan Paige Devine

Theses and Dissertations

To address the alarming rates of sexual assaults on college campuses, the 2013 Campus Sexual Violence Elimination Act required publicly funded colleges to provide some form of sexual assault intervention training to college students. While bystander intervention training is the most common form of primary prevention, there is little research indicating whether online or in-person bystander training is more effective at producing strong bystander self-efficacy and whether bystander intervention is actually occurring. Utilizing data from the 2017 Multi College Bystander Education Efficacy survey taken online by undergraduate students (N = 387) at a Midwestern university, an analysis of self-reported bystander …

Theses and Dissertations

College alcohol use remains a major public health concern, particularly on campuses in the Midwest. Heavy drinking has been linked to a number of deleterious consequences, ranging from poor academic performance and early school exit to injury or death. Many of the negative consequences linked to alcohol use carry with the possibility of regret. The purpose of this study is to explore the types of alcohol-related regret, any gender and class level differences in regret, and whether students become hesitant to drink alcohol after such a regret occurs. Data used for the study came from semi structured interviews with undergraduates …

Amyloid Precursor Protein And Insulin Homeostasis, Joshua Kulas

Theses and Dissertations

Alzheimer’s disease (AD) is a neurodegenerative disease in which the brain progressively deteriorates resulting in cognitive decline, language impairment, diminished spatial awareness, memory loss and ultimately, death. AD is the most prevalent neurodegenerative disease and the number of people afflicted by AD is expected to more than double in the next 30 years. AD is characterized in part by the formation of amyloid plaque deposits in the brain. It is known that these plaques are composed of the peptide Aβ, which aggregates as a function of age and is produced locally within the brain by cleavage of the Amyloid precursor …

Enhancement Of Phoshorus Removal Via Bioretention Cells Amended With Low Cost Materials, Nick Lindstrom

Theses and Dissertations

As bioretention systems are becoming an increasingly popular low impact development (LID) application for stormwater mitigation, they lack mechanisms that demobilize phosphorus (P) especially dissolved phosphorus (DP). In many cases, these LIDs release more P than is input due to a high P index derived from the plant material inherent within bioretention systems. The objectives of this project are to utilize low-cost water treatment residuals (WTR) as bioretention amendments to capture P. The adsorption characteristics are observed by means of batch level experiments to observe the P adsorption potential without the influence of hydraulic parameters, and column experiments to observe …

Women Engineering Majors' Choice To Stay: A Phenomenological Exploration Of Persistence Experiences, Victoria Morrissette

Theses and Dissertations

The historical underrepresentation of women in engineering persists for women engineering majors in college and once they enter the workforce. While some engineering disciplines have seen an increase in women students, overall the numbers still have fallen well behind other STEM disciplines despite years of research. Most studies on this issue have been quantitative and have looked at factors associated with why women leave engineering. This qualitative study, in contrast, gave women engineering majors the opportunity to share their experiences in answer to the question of why women choose to stay in an engineering major. Phenomenological methods, including semi-structured interviews, …

Plate Vibration Dispalcement Curve Measurement Using Pvdf, Aniket Nandkumar Pinjan

Theses and Dissertations

Beam and plate dynamics are often measured using accelerometers and in some cases laserbased systems. Natural frequencies, mode shapes, and deflections are then derived from these measurements. The work presented here describes a method to directly measure the deflection curve of a vibrating beam and plate using piezoelectric films. The sensor consists of constant shape segment of PolyVinyliDene Fluoride (PVDF) films bonded to the surface of the structure. We show in here that each segment of the sensor measures the deflection slope at its particular location. The overall lateral displacement curve of the structure (beam/plate) is calculated from these slopes …

The Role Of The Cholesterol Metabolite, 27-Hydroxycholesterol, In Colon Cancer Cells, Jessica A. Warns

Theses and Dissertations

Colorectal Cancer (CRC) is a major health concern with more than 600,000 deaths worldwide each year. Several risk factors for CRC exist including a diet rich in fat and cholesterol. However, the link between cholesterol and CRC is controversial. It is possible that oxysterols, which are active cholesterol metabolites, may correlate better with CRC than cholesterol itself. The most abundant oxysterol in the plasma is 27-hydroxycholesterol (27-OHC), which is a ligand for the nuclear receptors estrogen receptor (ER) and liver-x-receptor (LXR). 27-OHC has been shown to be involved in breast and prostate cancers, but its role in colon cancer remains …

Examining Determinants Of Patient Activation In Chronic Obstructive Pulmonary Disease: A Cross-Sectional Survey Study, Marnie M. Wetzstein

Theses and Dissertations

Introduction: Self-management plays a central role in the treatment chronic obstructive pulmonary disease (COPD). However, the patient characteristics necessary for effective self-management are not understood. The skills, confidence, and knowledge to engage in chronic disease self-care, known as patient activation, may play a key role in the capacity of people to self-manage COPD. How the complex, systemic nature of COPD influences patient activation has not been explored. Therefore, the purpose of this study was to examine the relationships among patient characteristics and health outcomes as determinants of patient activation among community-dwelling adults in the U.S. with COPD. The Revised Wilson …

Reliability Of The Styku 3d Whole Body Scanner For The Assessment Of Body Size In College Athletes, Joseph Daniel Derouchey

Theses and Dissertations

3-dimensional (3D) anthropometrics, such as volumes and surface area, have been shown to be important in predicting sport performance, and assessing health status, but most commercially available whole-body scanners are cost prohibitive. The main purpose of this study was to determine the test-retest reliability of a commercially available single camera 3D body scanning system to assess whole body and segmental circumferences, surface areas, and volumes of healthy collegiate athletes and students.

Cross-Country Comparisons In Health-Related Fitness Among European Children And Adolescents, Kevin Carver

Theses and Dissertations

Physical fitness is an important indicator of general health and sporting/athletic success. Several studies have highlighted large between-country differences in cardiorespiratory endurance, with little known about differences in other fitness components. A systematic review identified papers that reported descriptive Eurofit test results for apparently healthy (free from known disease/injury) 9- to 17-year-olds Europeans. An overall fitness index for each country was calculated as a population-weighted mean test-age-sex-specific z-score. Spearman’s correlations were used to calculate the association between country-specific fitness indices and broad socioeconomic/health indices. Performance indices were calculated for 18 countries using data collected on 2,779,165 children aged 9-17 years …

Genomic Regulation Of Abiotic Stress Response In The Soil Nematode Oscheius Tipulae, Riley Mcglynn

Theses and Dissertations

Oscheius tipulae is a species of free-living soil nematode that can be found in ecosystems worldwide. Because of this, individuals must be able to respond to heat, freezing, and desiccation stresses in order to survive. They do this by producing a suite of cellular responses, some of which are necessary to survive multiple stresses, and some are stress-specific. While these cellular responses are well known, the ways in which they are regulated in a genome-wide context are not. In this project, multiple high throughput sequencing and bioinformatics analyses were utilized to answer this question. First, the O. tipulae genome was …
