Sage-Grouse Nests In An Active Conifer Mastication Site, Charles P. Sandford, David K. Dahlgren, Terry A. Messmer

The Prairie Naturalist

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) have experienced long-term range-wide population declines and now may occupy less than 50% of their historic range (Schroeder et al. 2004). Conifer encroachment into sagebrush (Artemisia spp.) habitat was identified as a major conservation threat by the United States Fish and Wildlife Service (USFWS) as the agency reviewed the listing status of the species for possible protection under the Endangered Species Act of 1973 (USFWS 2013).

Conifer encroachment into sagebrush habitats negatively impacts sage-grouse at landscape scales (Doherty et al. 2008, Casazza et al. 2011, Baruch-Mordo et al. 2013). Sage-grouse will utilize …

Distribution And Occurrence Of Bat Species In North Dakota, Josiah J. Nelson, Paul R. Barnhart, Erin H. Gillam

The Prairie Naturalist

Prior to 2009, a detailed survey of occurrence and distribution of bats in North Dakota had not been conducted. Localized surveys, occurrence reports, and museum specimens provided the only records of bats in the state. Ongoing habitat loss, exploitation of natural resources, and the impending spread of white-nose syndrome to the western United States are major threats to bat populations of the region. The objective of this study was to document presence and distributions of bat species resident in North Dakota. From 2009 to 2012, multiple mist-netting and acoustic surveys were conducted to document species presence across North Dakota. A …

Characterization Of Sbip68: A Putative Tobacco Glucosyltransferase Protein And Its Role In Plant Defense Mechanisms, Abdulkareem O. Odesina

Electronic Theses and Dissertations

Plant secondary metabolites are essential for normal growth and development in plants ultimately affecting crop yield. They play roles ranging from appearance of the plants to defending against pathogen attack and herbivory. They have been used by humans for medicinal and recreational purposes amongst others. Glycosyltransferases catalyze the transfer of sugars from donor substrates to acceptors. Glucosyltransferases are a specific type of glycosyltransferases known to transfer glucose molecules from a glucose donor to a glucose acceptor (aglycone) producing the corresponding glucose secondary metabolite or glycone, in this case glucosides. It was hypothesized that SBIP68, a tobacco putative glucosyltransferase-like protein glucosylated …

Navigating Gender Inequality In Musical Subgenres, Adria Ryan Mclaughlin

Electronic Theses and Dissertations

This study looks at female musicians performing in subcultural rock genres commonly considered non-gender-conforming, such as punk rock, heavy metal, noise, and experimental. Twenty-four interviews were conducted with female musicians who reflected on their experiences as musicians. Themes emerged on women’s patterns of entry into music, barriers they negotiated while playing, and forces that may push them out of the music scene. Once women gained a musician identity, their gender functioned as a master status. They negotiated sexism when people questioned their abilities, assumed men played better, expected them to fail, held them to conventional gender roles, and sexually objectified …

Effects Of Complex Formation Of Dna With Positively Charged Polyamines And Polypeptides On The Products Of Oxidative Damage To Dna 2-Deoxyribose By Hydroxyl Radicals, Modeste N. Tegomoh

Electronic Theses and Dissertations

It is known that histones and other DNA-binding polycations protect DNA from radiation damage mediated by hydroxyl radicals. Until recently, this protection of DNA has mainly been attributed to compaction and aggregation. It was hypothesized that chemical repair of DNA sugar radicals by donation of hydrogen atom from polycations also significantly contributes to DNA protection. To test this hypothesis, the relative yields of low-molecular weight characteristic products of oxidation of DNA sugar were compared in X-irradiated samples of naked DNA and DNA complexes with a number of polycations by using an HPLC-based method of DNA damage product quantification. The variation …

Shifts In Ritual Response To Loss Due To Death: An Assessment Of Funeral Service Mourning Trends Over Time, Lawrence D. Childress

Electronic Theses and Dissertations

Bereavement, while universal, is experienced and expressed uniquely; it is both ultimate and particular. As the predominant social expression of grief, funerals are purported to be waning and/or transitioning to emergent, less conventional ceremonial forms. In this research, the possible salutary utility of funerals is outlined, and trends relative to the cost, nature (type), and prevalence of funeral services are examined relative to an extant data set from two funeral homes of shared ownership in northeast Tennessee. This data analysis of specific funeral trends in south central Appalachia is juxtaposed against the broader backdrop of current theoretical, clinical, and socio-cultural …

Thermodynamic Modeling Of Aqueous Geochemistry Of Chlorine Salts: Application To Stability And Habitability Of Liquid Brines On Mars, Amira Elsenousy

Graduate Theses and Dissertations

The WCL (Wet Chemistry Lab) instrument on board the Mars’s Phoenix Lander has identified the soluble ionic composition of the soil at the landing site. Two important ions were detected at the landing site; perchlorates (ClO4-) with a concentration of ~ 2.4 wt% and chlorides (Cl-) with a concentration of 0.54 wt%. Between chloride and perchlorate ions three other oxidized ions exist and called chlorine ions: hypochlorite ClO - (ox. state +1), chlorite ClO2- (ox. state +3) and chlorate ClO3- (ox. state +5). These oxidized ions might be existed as intermediate species on the surface of Mars but remained undetected. …

A Physiologically-Based Pharmacokinetic Model For Vancomycin, Rebekah White

Undergraduate Honors Theses

Vancomycin is an antibiotic used for the treatment of systemic infections. It is given

intravenously usually every twelve or twenty-four hours. This particular drug has a

medium level of boundedness, with approximately fty percent of the drug being free

and thus physiologically eective. A physiologically-based pharmacokinetic (PBPK)

model was used to better understand the absorption, distribution, and elimination of

the drug. Using optimal parameters, the model could be used in the future to test

how various factors, such as BMI or excretion levels, might aect the concentration

of the antibiotic.

Evaluating The Impacts Of Respondent Errors In Arms: A Case Of Farm Service Agency Loans, Louise Nicole Mcminn

Graduate Theses and Dissertations

Many studies have used the U.S. Department of Agriculture’s (USDA) Agricultural Resource Management Survey (ARMS) to research various aspects involving the agricultural sector in the United States. Since nonresponse and inaccurate reporting may cause significant bias in statistical analysis, research was conducted to determine the magnitude of response error on the farm debt section of the ARMS Phase III. A multinomial logit model identified demographic, structural, and financial characteristics of FSA Farm Loan Program (FLP) borrowers who refused to indicate if they had end of year farm debt, or who accurately or inaccurately classified their farm operations as having end …

Ibuprofen Ameliorates Fatigue- And Depressive-Like Behavior In Tumor-Bearing Mice, Diana M. Norden, Donna O. Mccarthy, Sabahattin Bicer, Raymond Devine, Peter J. Reiser, Jonathan P. Godbout, Loren E. Wold

College of Nursing Faculty Research and Publications

Aims: Cancer-related fatigue (CRF) is often accompanied by depressed mood, both of which reduce functional status and quality of life. Research suggests that increased expression of pro-inflammatory cytokines is associated with skeletal muscle wasting and depressive- and fatigue-like behaviors in rodents and cancer patients. We have previously shown that treatment with ibuprofen, a nonsteroidal anti-inflammatory drug, preserved muscle mass in tumor-bearing mice. Therefore, the purpose of the present study was to determine the behavioral effects of ibuprofen in a mouse model of CRF.

Main methods: Mice were injected with colon-26 adenocarcinoma cells and treated with ibuprofen (10 mg/kg) in the …

Separation Of Oil From A Brackish Water Stream, Kayli A. Quinton

Chemical Engineering Undergraduate Honors Theses

In the past 40 years, a variety of enhanced oil recovery (EOR) methods have been developed and applied to mature and mostly depleted oil reservoirs. Chemical and sonic stimulation are two enhanced oil recovery methods in which emulsions are created either as a primary or secondary effect. The resulting emulsion viscosity is considerably lower than that of dry crude thus increasing permeability of and recovery from pay zones. During Chemical enhanced oil recovery, caustic or preformed surfactants are injected into oil reservoirs, which results in flooding and periodic breakthrough of stable oil-water emulsions. The emulsions from chemical enhanced oil recovery …

Computational Capacity And Energy Consumption Of Complex Resistive Switch Networks, Jens Bürger, Alireza Goudarzi, Darko Stefanovic, Christof Teuscher

Electrical and Computer Engineering Faculty Publications and Presentations

Resistive switches are a class of emerging nanoelectronics devices that exhibit a wide variety of switching characteristics closely resembling behaviors of biological synapses. Assembled into random networks, such resistive switches produce emerging behaviors far more complex than that of individual devices. This was previously demonstrated in simulations that exploit information processing within these random networks to solve tasks that require nonlinear computation as well as memory. Physical assemblies of such networks manifest complex spatial structures and basic processing capabilities often related to biologically-inspired computing. We model and simulate random resistive switch networks and analyze their computational capacities. We provide a …

Variation Between Peripheral And Center Achene Morphology And Attributes Of Achene Germination In The Invasive Species, Centaurea Melitensis, Kandee Bain

Electronic Theses, Projects, and Dissertations

Invasive species are often successful and problematic because of their ability to persist in disturbed and undisturbed environments despite weed management practices. Understanding reproduction and dispersal strategies in these species can aid in developing management approaches to help control their spread. Centaurea melitensis, a nonnative invasive with European origins, is found in disturbed areas of southern California. It produces three different types of flower heads that develop at different times and at different locations on the plant during the growing season. The chasmogamous (CH) flower heads are located at the top of the plant, the initial cleistogamous (iCL) heads …

Defining Treatment Response In Trichotillomania: A Signal Detection Analysis, David C. Houghton, Matthew R. Capriotti, Alessandro S. De Nadai, Scott N. Compton, Michael P. Twohig, Angela M. Neal-Barnett, Stephen M. Saunders, Martin E. Franklin, Douglas W. Woods

Psychology Faculty Research and Publications

The Massachusetts General Hospital Hairpulling Scale (MGH-HPS) and the NIMH Trichotillomania Severity Scale (NIMH-TSS) are two widely used measures of trichotillomania severity. Despite their popular use, currently no empirically-supported guidelines exist to determine the degrees of change on these scales that best indicate treatment response. Determination of such criteria could aid in clinical decision-making by defining clinically significant treatment response/recovery and producing accurate power analyses for use in clinical trials research. Adults with trichotillomania (N = 69) participated in a randomized controlled trial of psychotherapy and were assessed before and after treatment. Response status was measured via the Clinical …

Identifying And Predicting Rat Behavior Using Neural Networks, Jonathan A. Gettner

Master's Theses

The hippocampus is known to play a critical role in episodic memory function. Understanding the relation between electrophysiological activity in a rat hippocampus and rat behavior may be helpful in studying pathological diseases that corrupt electrical signaling in the hippocampus, such as Parkinson’s and Alzheimer’s. Additionally, having a method to interpret rat behaviors from neural activity may help in understanding the dynamics of rat neural activity that are associated with certain identified behaviors.

In this thesis, neural networks are used as a black-box model to map electrophysiological data, representative of an ensemble of neurons in the hippocampus, to a T-maze, …

Two-Phase Anaerobic Digestion To Reduce The Nox Emission Potential Of Biogas, Nathaniel Manuel Olivas

Master's Theses

Anaerobic digestion can be used to decrease the mass of organic wastes to be disposed of while producing useful biogas (CH₄ and CO₂) for heat or power production, but in air basins with strict emissions limits, biogas combustion is difficult to implement due to the high costs of controlling NOx emissions. NOx production can be minimized by blending H₂ gas with CH₄ at a volume ratio of 15:85 H₂:CH₄, which allows burning at ultra-lean air-to-fuel ratios. For biogas systems, a potential low-cost NOx control strategy is to produce H₂-CH …

Predicting Invasive Range Of Eucalyptus Globulus In California, Anthony J. Lopez

Master's Theses

Eucalyptus globulus is the subject of intense debate in California. Its invasive potential, aggressive growth, reproductive biology, and association with fire make the prediction of spread important in California. Two modeling simulations, Climex and Maxent, will illustrate the distribution and potential growth range of E. globulus in California based on climate and presence. Modeling the potential range of growth will predict invasive spread. The anticipated result is the continued spread of E. globulus in coastal regions with adequate moisture and suitable climate. Predicting the range of E. globulus in California dictates management strategy and is key for preventing further introduction, …

This article describes current practices and needs associated with water and gas conservation among Southern California greenhouse growers, Post-Harvest Processors (PHPs), and agricultural associations. Two communication forums were held with the goal of educating the local gas company and small growers and PHPs on the most compelling needs and best practices to support sustainability while improving profit. While some growers and PHPs have made significant investment in energy and water conservation advanced technologies, all participants expressed the desire to work with local utilities towards greater water and energy conservation opportunities that are customized to specific needs.

Best Practices In Community Garden Management To Address Participation, Water Access, And Outreach, Luke Drake, Laura Lawson

Journal of Extension

As community gardens expand across the U.S., Extension professionals can support them not only in horticultural education but also in planning and organization. Knowledge of community garden management is helpful in this regard. Existing research focuses on outcomes and criteria for successful gardens, but is less clear about how community gardens work. We use ethnographic methods to examine community garden management in New Jersey. Spatial and social contexts shape key issues such as water access, participation, and horticultural techniques. Extension professionals can more effectively support community gardens by tailoring their advice to these contexts.

Understanding Public Engagement In Water Conservation Behaviors And Knowledge Of Water Policy: Promising Hints For Extension, Pei-Wen Huang, Alexa J. Lamm

Journal of Extension

Sustaining water resources is a primary issue facing Florida Extension. The study reported here identified how experience with water issues and familiarity with water policies affected individuals' engagement in water conservation behaviors. A public opinion survey was conducted online to capture Florida residents' responses. The findings indicated experience with water issues and familiarity with water policies were predictors of individuals' engagement in civic water conservation behaviors. Given this, Extension educators developing programs and educational materials about water conservation behaviors should cover information related to water policies because participants will be more inclined to engage if they are familiar with policies.
