Brook Trout Behavioral Thermoregulation And Habitat Selection In A Small Michigan Coldwater Stream: Implications For Successful Management, Justin Emory Wegner

Masters Theses

Global warming and conversion of forests for urbanization, agriculture and mineral extraction are increasing water temperatures throughout Brook Trout’s range causing population declines; particularly in populations persisting in marginal habitats and in the southern limits of their distribution. The Brook Trout is an ectotherm that can cope with elevated water temperature by moving to coldwater refuge such as groundwater seeps, coldwater tributary confluences, and headwaters. Availability of coldwater refuge is vital for the survival of Brook Trout populations threatened by increasing water temperatures. I used radio telemetry to study the movement, habitat use, and behavioral thermoregulation of Brook Trout living …

The Effect Of Dietary Specialism And Generalism On Evolutionary Longevity In An Early Paleogene Mammalian Community, Samantha Glonek

Masters Theses

This study examines the relationship between relief index (RFI) on first and second mandibular molars and longevity of the genus. The molars were extracted from small-bodied, arboreal mammals during the late-Paleocene, early-Eocene in the Bighorn Basin in Wyoming. This study site is a well-known location to research and study fossil mammals of this time period. The study was conducted and analyzed at the genus level due to the relatively small number of specimens available and identifiable at the species level. Dietary breadth, or how broad or narrow a dietary preference is for a mammal, is an area of concentration within …

Surveying The Circular Rep Encoding Single Stranded (Cress) Dna Viral Consortium Found In Invasive Quagga Mussels (Dreissena Rostriformis Bugensis) And Sediments Of The Central Lake Michigan Benthos, Nicholas Gezon

Masters Theses

Globalization and resulting increases in international trade has allowed for the movement of species between almost all ecosystems on Earth. The Great Lakes in particular has seen a number of high impact invasive species that have moved in following the opening of the lakes to intercontinental shipping trade. This research specifically focuses on the benthic community of Lake Michigan which has seen significant community shifts including declines of the amphipods Diporeia spp. and the expansion of invasive quagga mussels (Dreissena rostriformis bugensis). Little is known about the viral community in the benthos of Lake Michigan and how …

Radiofrequency Processing For Inactivation Of Salmonella Spp. And Enterococcus Faecium Nrrl B-2354 In Whole Black Peppercorn And Ground Black Pepper, Xinyao Wei

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Black pepper has been implicated in several foodborne illness outbreaks and food product recalls due to Salmonella contamination. Conventional decontamination methods for black pepper are challenged by harmful residues or quality deterioration. Radiofrequency (RF) heating reduces the come-up time which allows to design a high-temperature short-time processing to inactivate Salmonella with minimal deterioration in product quality. The objectives of this study were to investigate RF heating for inactivation of Salmonella in whole black peppercorn and ground black pepper samples, evaluate Enterococcus faecium NRRL B-2354 as a surrogate for Salmonella, and assess quality deterioration during RF heating of whole black peppercorn …

Increasing Cis-Lycopene Content Of The Oleoresin From Tomato Processing Byproducts Using Supercritical Carbon Dioxide And Assessment Of Its Bioaccessibility, Lisbeth Vallecilla Yepez

Department of Food Science and Technology: Dissertations, Theses, and Student Research

In recent years, health- and wellness-promoting foods have been one of the major focus of consumers; therefore, the food industry is increasing its efforts in developing these food products. Tomatoes, tomato-food products and their byproducts have gained special attention in virtue of the carotenoids-rich source that they represent, especially lycopene (~90%). The role of lycopene in human diet has been highlighted as a result of its direct relationship with the decrease of chronic diseases. Nevertheless, lycopene is water-insoluble making its extraction simple with organic-toxic solvents; in addition, lycopene degrades easily with light, time, and storage. Lycopene exist in nature mostly …

Effects Of Environmental Enrichment On Self-Administration Of The Short-Acting Opioid Remifentanil In Male Rats, Rebecca S. Hofford, Jonathan J. Chow, Joshua S. Beckmann, Michael T. Bardo

Psychology Faculty Publications

Background

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil.

Methods

Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of …

Creativity and Change Leadership Graduate Student Master's Projects

PROJECT ABSTRACT

Rebranding Visual Feedback as a Product

Why do visuals work and why do they have such impact on the process of change? Because visuals connect directly with feelings, they have the power to improve the life of others. They have the power to improve and enrich communication. They have the power to handle information overload and they have the power to bridge cultural differences. ‘Images speak louder than words’ because images are connected with emotions in our long term memory. When ten different persons look at one single image, they see ten different things. Like a mirror, the …

On The Influence Of Spatio-Temporal Analysis On Clustering And Recommendation, Madhuri Debnath

Computer Science and Engineering Dissertations - Archive

In this dissertation, we propose efficient frameworks to analyze spatio-temporal data. In the first part of the dissertation, we use a clustering based method to mine useful information from trajectory data. Existing trajectory clustering algorithms have focused on geometric properties and spatial features of trajectories. In contrast to existing algorithms, we propose a new framework to cluster sub-trajectories based on a combination of spatial and non-spatial features. In the second part of dissertation, we propose a unified framework to build recommendation systems by analyzing human movement data. We propose recommendation frameworks to recommend POI locations and travel routes that use …

Life-Long Creativity: Changing The Narrative Of Aging And Retirement, Jennifer K. Gippel Dr

Creativity and Change Leadership Graduate Student Master's Projects

The current narratives and stereotypes around retirement and aging are both inaccurate and incomplete. The popular media regularly portrays retirees and older citizens as blissfully happy but bland; or physically feeble and forgetful. Rarely are they portrayed as achievers and vibrant problem solvers. Instead they are perceived by policy makers as a problem to be solved. This project offers a different narrative ― one that presents retirement and aging as a unique time of creative opportunity, possibility, and freedom to choose. The primary outcome of the project is two chapters of a book entitled: Retirement by design: How to discover …

Pcb-Associated Steatohepatitis And The Role Of Nuclear Receptors., Heather Brooke Clair

Electronic Theses and Dissertations

Metabolic diseases, including fatty liver disease, hyperglycemia, and obesity, result when body systems responsible for managing allostasis (dynamic homeostasis across systems) are pressured beyond their collective compensatory reserve. Nutritional excess contributes to this state, the capacity of which is limited by genetic variation, and failure of one system will gradually lead to pathological overload in the others. Agents which act directly on the communication machinery linking these connected systems can also change the point at which allostatic load becomes allostatic overload. Environmental exposure to polychlorinated biphenyls (PCBs), a class of persistent organic pollutant, is associated with a specific form of …

Role Of Human Arylamine N-Acetyltransferase 1 In Tumorigenesis And Cancer Biology., Marcus William Stepp

Electronic Theses and Dissertations

Human arylamine N-acetyltransferase 1 (NAT1) is a well-known phase II metabolic enzyme that has been associated with carcinogenesis. Its role in the biotransformation of aromatic and heterocyclic amine carcinogens has been investigated for many years, but more recent investigations focus on a possible endogenous role of human NAT1 in cancer initiation and progression. To further explore and understand possible endogenous roles for NAT1, we conducted in vitro enzymatic reactions, in vivo studies using homozygous high (rapid) or low (slow) NAT2 activity congenic F344.WKY rats, and genetically modified human breast cancer cell lines. Human NAT1 and rodent NAT2 hydrolyzed acetyl-coenzyme …

Farmscapes : Picturing Land Transformation In Nineteenth-Century America., Eileen L Yanoviak

Electronic Theses and Dissertations

This dissertation examines American farmstead imagery of the nineteenth-century and how those images reflect the environmental history of the North. In this study, images of farms illustrate, through the landscape, the transition from subsistence farming to agribusiness that fundamentally changed American life and the land over the century. By comparing the actual ecological and economic conditions of the farm and farmer to the images depicted by artists, it is possible to see both representations of change and the persistence of the agrarian myth in spite of dramatically different realities. This study focuses on the process of change in the American …

Metabolic Regulation Of Myocardial Adaptation To Exercise., Andrew Alan Gibb

Electronic Theses and Dissertations

While the benefits of exercise affect several organs, a significant adaptive response occurs within the heart. Exercise promotes cardiac growth, increases angiogenesis, and enhances cardiac function and these adaptations are associated with a cardioprotective phenotype. Additionally, extensive evidence shows that exercise dynamically regulates myocardial metabolism. This can be attributed to both changes in hormonal stimulation, increases in bioenergetic demand, and the bioavailability of circulating substrates. However, it is unclear whether these changes in metabolism contribute to physiologic cardiac growth. We reason that exercise-induced changes in metabolism are required to balance the catabolic and anabolic reactions needed for growth. Specifically, we …

Electronic Theses and Dissertations

Teachers are important to student achievement. The selection of teachers in most schools in the United States is the responsibility of the principal. This study examined preferences of school leaders for teacher applicant characteristics. An exploratory factor analysis of the results (N = 209) of the Preferred Teacher Applicant Characteristics Survey (PTACS) determined four underlying dimension of the PTACS instrument: personal characteristics, professional characteristics, ancillary characteristics, and demographic characteristics. These became the dependent variable in a series of linear multiple regression analyses to examine the relationship between a school’s characteristics – poverty, school performance category, average teacher experience, and the …

Effect Of Total Body Iron On Metabolic Dysfunction Among U.S. Females In The Nhanes 2003-2010, Aged 12-49., Joseph Michael Carhart

Electronic Theses and Dissertations

Experimental and epidemiological studies have reported positive associations between iron parameters and metabolic dysfunction including: Type 2 diabetes mellitus (T2DM) (1-6), metabolic syndrome (7-15), non-alcoholic fatty liver disease (NAFLD) (16-22) and insulin resistance (23,24) with a number of studies showing that reductions in total body iron via dietary modification (e.g., reducing red meat intake) or phlebotomy lead to increases in insulin sensitivity (25), decreases in insulin resistance (26), and reductions in the prevalence of complications associated with T2DM (5, 27), metabolic syndrome (28) and NAFLD (22, 29). Moreover, the risk associated with these outcomes and total body iron differ between …

This Is Just A Phase : The Impact Of Population Structure On Haplotype Phasing And Linkage Disequilibrium Measures At Functional Genetic Sites., Roxanne Kaaren Leiter

Electronic Theses and Dissertations

The block-like structure of the human genome has been the subject of many scientific papers and is of practical significance in large-scale genome-wide association studies. How stringent haplotype block boundaries are within and between populations has been the subject of ongoing debate within human population genetics. This thesis will contribute to the description of universal and population-specific haplotype blocks at functional sites, namely across the IL-10 gene family (including IL-10, IL-19, IL-20 and IL-24), which is involved in a number of immune system processes, and MAPKAP-K2, an adjacent and functionally significant kinase gene. Beyond the description of blocks across these …

Electronic Theses and Dissertations

Seeking to understand the media’s influence over society, and the way the media motivate us to conform to specific ideals, this thesis focuses on how female bodies in particular are consistently idealized and objectified in mainstream media. Through television, print, and the internet, the media serve as our world’s main means of mass communication. Noting this, this text seeks to understand the female body’s historical objectification through art history and genres of the nude, how this has transferred to contemporary media, and finally states that these stereotypes and norms can be challenged through the work of contemporary artists. By reclaiming …

This thesis includes the novel’s introductory scene and its first principle section, “Food of the Gods.”

The Role Of Kinases And Phosphatases In The Pathobiology Of Porphyromonas Gingivalis., Sarah Whitmore

Electronic Theses and Dissertations

Periodontal diseases result from the interplay between the dysregulation of the host inflammatory response and the actions of a dysbiotic bacterial community. These chronic inflammatory conditions affect persons on a worldwide scale. P. gingivalis is strongly implicated as a key periodontal pathogen in the more severe manifestations of periodontal diseases such as periodontitis. A core element of P. gingivalis pathogenicity is its dysregulation of innate immunity, including suppression of IL-8 production by gingival epithelial cells. The NF-κB family of related transcription factors plays a central role in regulating many important aspects of innate immune responses. NF-κB RelA/p65 homodimers regulate transcription …

Deficiency Of Rdh10 Causes Cleft Secondary Palate In Mouse., Swetha Raja

Electronic Theses and Dissertations

The focus of this project is to understand the role of Retinoic Acid (RA) produced by RDH10-mediated metabolism of Vitamin A in palate development. For 80 years now, we have known that dietary restriction of RA/Vitamin A can cause cleft palate but we have failed to understand how RA deficiency causes cleft palate. Our gap in knowledge about how RA deficiency causes cleft palate is mainly owing to the fact that we lack a model system to study such defects. The aim of this thesis research project was to determine if conditional inactivation of the Vitamin A metabolic gene Rdh10 …

Examining The Relationships Between Prenatal Tobacco Exposure, Temperament, And Cognitive Ability In Early Childhood, Sam Pérez-González

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prenatal tobacco exposure (PTE) has been extensively researched and consistently associated with outcomes indicative of self-regulation deficits (e.g., ADHD, behavioral problems, and impaired cognitive function). Self-regulation is a multifaceted construct critical to children’s successful behavioral, emotional, and academic adjustment and involves the integration of a cognitive component (executive function) and a temperamental component (effortful control). Previous research suggests temperament may be a pathway through which PTE affects children’s future behavior and cognitive outcomes, but such studies have been limited to infancy and have not included measures of executive function. Thus, the current study had three aims: a) to examine clusters …
