Mechanism Of By Product Formation From Different Water Matrices By Chlorination And Chloramination, Victoria Jane Hawkes

Master's Theses and Capstones

Application of chlorine-based disinfection to drinking water and wastewater leads to the formation of disinfection by-products that are harmful to human health. This paper presents research performed on the formation mechanisms of trihalomethanes (THMs) and nitrosamines (specifically NDMA) from chlorine-based disinfection practices. The formation of THMs and nitrosamines was investigated under a range of water matrices and disinfection conditions by developing a set of laboratory prepared water matrices containing natural organic matter (NOM), bromide and ammonium. In addition, two pretreated surface waters and one secondary treated wastewater effluent were selected to link experimental results to practice. THMs and nitrosamines were …

Going Beneath The Surface: The Ecology Of Metalimnetic Cyanobacteria Layers In Three New Hampshire Lakes, Sabina Perkins

Master's Theses and Capstones

Cyanobacteria blooms take different forms: surface scums, subsurface epilimnetic blooms, benthic mats, and in some lakes, metalimnetic layers. There is limited field research on the seasonal behavior of metalimnetic layers and the contribution of layer-produced cyanotoxins to the overall toxin profile of New Hampshire lakes. Three lakes in New Hampshire were monitored monthly pre-summer stratification through post-fall mixis in 2018, tracking the formation and persistence of deep-water cyanobacteria layers and the physical/chemical/light environments where they were found. Cyanobacteria abundance and dominance were quantified through cell counts using an Imaging Flow Cytobot (IFCB) and with phycocyanin fluorescence estimates. Persistent, nearly monospecific …

Missed Moments: Kodak’S Failure To Define The Consumer Market For Digital Photography, Paul T. Moon Jr

History Theses

The focus of this thesis is to provide an expanded interpretation of the decline of the Eastman Kodak Company. Kodak is a company synonymous with cameras, pictures, and photography. The American photographic giant created a vast empire that was able to dominate the industry for the better part of the Twentieth Century. Yet, it missed the opportunity to develop its digital camera technology. This makes Kodak an interesting study in business decision making in the face of advancing disruptive technology.

In a historical context, there is a lack of work that deeply inspects the fall of the Kodak company in …

Sex Differences In Ethanol Modulation Of Dopamine Release In The Mesolimbic Reward System, Mandy Parsons

Undergraduate Honors Theses

This thesis seeks to synthesize previous studies that have shown sex differences in response to drugs of abuse, specifically cocaine and alcohol. These differences have been noted through the study of behavior, nitric oxide levels in the medial amygdala, and dopamine release within the mesolimbic system. Importantly, it has been consistently found that these differences seem to correlate with the changing hormonal environment produced by the estrus cycle in females. Furthermore, this thesis examines new research on how the estrus cycle modulates dopamine release within the reward circuit through the utilization of fast scan cyclic voltammetry and microdialysis techniques. A …

Including Indigenous Knowledge Systems In Environmental Assessments: Restructuring The Process, Rachel Arsenault, Carrie Bourassa, Sibyl Diver, Deborah Mcgregor, Aaron Witham

Articles & Book Chapters

Indigenous peoples around the world are concerned about the long-term impacts of industrial activities and natural resource extraction projects on their traditional territories. Environmental impact studies, environmental risk assessments (EAs), and risk management protocols are offered as tools that can address some of these concerns. However, these tools are not universally required in jurisdictions, and this Forum intervention considers whether these technical tools might be reshaped to integrate Indigenous communities’ interests, with specific attention to traditional knowledge. Challenges include unrealistic timelines to evaluate proposed projects, community capacity, inadequate understanding of Indigenous communities, and ineffective communicatio, all of which contribute to …

More Than Things, Scarlet Galvan

Scholarly Papers and Articles

The often invisible labor of serials, technical services, metadata, and electronic resources workers sits in the space between required and preferred, assessment and surveillance. Although libraries and information workers did not explicitly create the systems many of us live in, we are responsible for their everyday functioning. In many ways the narratives from technical services to the library are centered in objects: item counts, COUNTER stats, door counts, discovery, and other transactional data. And yet, we are stewards and maintainers, innovators and storytellers of the countless ways these objects are experienced. How can we help our colleagues understand the outreach …

Cybersecurity Paradigm Shift, The Risk Of Net Neutrality Repeal To Energy Reliability, Public Safety, And Climate Change Solutions, Catherine J. K. Sandoval

Faculty Publications

This Article contends that the Federal Communications Commission’s (FCC) January 2018 repeal of net neutrality rules creates cybersecurity vulnerabilities for the energy sector and other critical infrastructure. Unbridled from enforceable net neutrality rules, Internet Service Providers (ISPs) create systemic supply chain risks as the Internet has become embedded into the energy sector’s distributed ecosystem. This Article argues that cybersecurity has been primarily viewed from a “hacker paradigm” that obscures systemic threats such as those posed by an ISP since firewalls and traditional cybersecurity techniques do not protect against ISP conduct. The Article contends that the FCC’s failure to consider the …

The Functional And Structural Analysis Of Drosophila Robo2 In Axon Guidance, Lafreda Janae Howard

Graduate Theses and Dissertations

In animals with complex nervous systems such as mammals and insects, signaling pathways are responsible for guiding axons to their appropriate synaptic targets. Importantly, when this process is not successful during the development of an organism, outcomes include catastrophes such as human neurological diseases and disorders. It is vital to determine the underlying causes of such diseases by understanding the development of the nervous system. There are many pathways that have been identified to play a role in this, however, we lack an understanding of how these pathways can promote such diverse outcomes in different populations of neurons. These pathways …

Phylogenetic Analysis Of Palisota (Commelinaceae) Using Chloroplast And Nuclear Regions, Alexandra H. Crum

Masters Theses

Palisota (Commelinaceae) differs from other Commelinaceae genera in androecial and pollen characters, a fleshy berry-type fruit, and anatomical characters. Palisota has been divided into two sections based on uniseriate vs. biseriate seed arrangement. Molecular phylogenetic analyses in Commelinaceae have placed Palisota near the base within the family, although its precise position is unclear. We sequenced chloroplast (matK, rbcL, rps16, and trnL-trnF, psbI-psbK, atpB-rbcL, atpF-atpH and psbA-trnH intergenic spacers) and nuclear (AT103) regions in 15 of approximately 26 species of Palisota and 15 outgroup species. Phylogenetic analyses were performed using maximum likelihood and Bayesian methods, with the …

The Association Between Dietary Niche Variation In Rodents And Climate Change Across The Paleocene-Eocene Thermal Maximum, Hannah K. Vermeer

Masters Theses

Mammalian teeth play a crucial role in food acquisition and breakdown and are therefore closely tied to dietary niche. This study reconstructed the diet of early Paleogene paramyid rodents across the Paleocene-Eocene Thermal Maximum (PETM) climatic event in an effort to understand the role of climate in mammalian dietary niche change. Dietary niches were quantified using three dental topographic measures: Dirichlet normal energy, relief index, and orientation patch count rotated. A Kruskal-Wallis test was conducted over eight time periods to determine if each of the dental topographic measures (i.e., diet) varied over time. Regression analysis of these measures with climatic …

Habitat Use And Tributary Occupancy Of The Threatened River Redhorse (Moxostoma Carinatum) In The Grand River, Mi, Usa., Nicholas Michael Preville

Masters Theses

The resiliency of our aquatic ecosystems hinges on our ability to protect the native species that reside within them. The river redhorse (Moxostoma carinatum) is one such example and populations have become low enough to warrant listing by the State of Michigan. Causes of decline include overfishing, habitat alteration, and lack of knowledge of basic life-history attributes including their use of non-spawning habitat and spawning locations. In order to understand the river redhorse’s habitat use we implanted 15 individuals with radio transmitters and tracked their locations over the course of a summer. Tagged river redhorse were found to …

Biological Invasions On A Large Scale: Investigating The Spread Of Baby’S Breath (Gypsophila Paniculata) Across North America, Sarah K. Lamar

Masters Theses

Invasive species are a serious threat to biodiversity worldwide. While the impacts of invasive species increase annually, many gaps in our understanding of how these species invade, adapt, and thrive in the novel ecosystems into which they are introduced remain. This thesis aimed to add to our knowledge of invasion science, using the perennial forb Gypsophila paniculata as a study system. Gypsophila paniculata is a shrub native to the Eurasian steppe that was introduced into North America in the late 1800’s. After introduction, G. paniculata quickly spread and now occupies diverse ecosystems across N. America. In chapter II of this …

Using Landscape Genetics To Understand Connectivity Of An Island Population Of Eastern Massasauga Rattlesnakes (Sistrurus Catenatus), Nathan Kudla

Masters Theses

Populations that experience low levels of gene flow commonly display increased levels of inbreeding, lower genetic diversity, and reduced adaptive potential. Landscape genetics allows for spatial and genetic information to be analyzed simultaneously to better understand how the landscape influences gene flow. The eastern massasauga rattlesnake (Sistrurus catenatus) is a federally threatened viper found in wetlands throughout the Great Lakes region. Many remaining populations are small and isolated due primarily to habitat loss. Atypical from a range-wide perspective, eastern massasaugas on Bois Blanc Island (BBI), Michigan live in a relatively undisturbed landscape with a potential for high connectivity …

Evaluating Remote Site Incubators To Support Restoration Of Arctic Grayling In Michigan, Alan J. Mock

Masters Theses

Remote site incubators (RSIs) have been used to rear salmonid fish eggs along streams in the Pacific Northwest since the 1980s. Recently, the successful use of RSIs for Arctic Grayling Thymallus arcticus restoration in Montana has sparked a renewed interest to reestablish the species in Michigan. To support future reintroduction efforts of Arctic Grayling in Michigan, I evaluated RSIs in three Michigan streams during 2018 and 2019 using Rainbow Trout Oncorhynchus mykiss eggs (as surrogates for Arctic Grayling). My objectives were to: (1) compare hatching success between two different RSI designs (19-L vs. 265-L RSIs), and (2) test whether the …

Assessing Bioavailability, Metal Fractionation, Magnetic Susceptibility, And Organic Matter Interactivity In Mine-Waste Contaminated Sediments In Turkey Creek, Joplin, Missouri, Zachary Joseph Collette

Graduate Theses/Dissertations

Joplin, Missouri, part of the Tri-State Mining District (TSMD), has a long history of mining that resulted in mine waste piles proximal to the mines throughout the area. A local lead smelter also resulted in smelter fallout in Joplin. Mine waste pile runoff and local smelter fallout resulted in contamination of sediments, soils, and waterways. In the 1990s, remediation of residential soils and play areas began after blood lead levels in children were much higher than the national average. Soon afterwards, the chat piles were removed and used for beneficial reuse purposes. In May of 2011, an EF5 tornado devastated …

The Use Of An Individualized Levels System And Extinction To Increase Task Compliance And To Decrease Aggressive Behavior With A Child With Autism, Savanna A. Chojnacki

Graduate Theses/Dissertations

In a token economy level system, as an individual progresses from one task level to the next, there is an increase in the demand of tasks and an increase in the magnitude of reinforcers earned. The motivation for the individual in level systems stems from the increasing of value of reinforcers earned at each level. In this study a level system in concordance with an extinction procedure for aggressive behaviors was employed as a behavioral intervention. In this single-subject design study, a 5-year-old boy with autism was observed across a variety of 15 minute teaching sessions, implementing synchronously, the reinforcement …

Al Qaeda and the Islamic State of Iraq and Syria (ISIS) have demonstrated the intent and capability of chemical …

Geomorphic And Land Use Controls On Headwater Channel Morphology In Mark Twain National Forest, Grace F. Roman

Graduate Theses/Dissertations

Prescribed burning has been used over the past two decades to manage forests and restore shortleaf pine-oak woodlands in Mark Twain National Forest (MTNF). While soil studies have been completed, no assessments of burning practices on small drainage channel systems have yet been done. Headwater streams may account for more than two-thirds of total stream length and are important to the maintenance of hydrologic connectivity in watersheds. This study’s focus is on understanding the relationship between frequency of forest burning and channel morphology (size, shape, and substrate) of headwater streams (km²). A combination of field measurements, geo-processing methods, …

Elucidating Immune Signaling Of Influenza A Virus And Aspergillus Fumigatus Co-Infections Through Pioneered Model Development, Meagan Danyelle Rippee-Brooks

Graduate Theses/Dissertations

Bacterial co-infections with influenza A virus (IAV) are extremely serious and life-threatening. However, there exists limited understanding about the importance of fungal infections with IAV. Clinical case reports indicate that fungal co-infections do occur and suggest the IAV pandemic of 2009 had a propensity to predispose patients to secondary fungal infections more than previous IAV strains. IAV-fungal co-infections are marked by high mortality rates of 47 to 61% in previously healthy individuals between the ages of 20 and 60. Yet, the variables involved in this co-infection remain undetermined. I achieved effective recapitulation of this co-infection using a C57Bl/6 murine (mouse) …

Mothers Of Intention: Women In The Ku Klux Klan And Massive Resistance, 1954-1968, Michele R. Johnson

Graduate Theses and Dissertations

This dissertation examines women in the Massive Resistance movement and the Ku Klux Klan of the classic Civil Rights period, 1954-1968. Specifically, it illustrates the way in which these women used their assigned gender roles as women, and specifically as mothers, to further white supremacist goals. White women have been an integral part of white supremacy in the United States from the beginning, yet are rarely portrayed as such. White supremacist movements are most often viewed through a male lens and gender in white supremacy is most often focused on how white men perform gender within the movements. While that …

Influences Of Autism Spectrum Disorder On Sensory And Emotional Responses To Smell And Taste Cues, Asmita Singh

Graduate Theses and Dissertations

Autism spectrum disorder (ASD) is a developmental disability that causes social, communication, behavioral and sensory challenges. The prevalence has been on a rise, with the latest reports stating 1 in 59 children is diagnosed with ASD. These challenges play a significant role in feeding behavior, leading to reduced nutrition among individuals. Much research in this field has been attributed to children, however, this study was focused on the adult population, in an attempt to improve their quality of life. Building on previous findings and knowledge gaps, the objectives of this thesis were two-fold: To better understand the sensory experiences of …

Normative Pragmatic Selfhood: A Pragmatist Conception Of Value For Marginal Cases, Sam Noel Johnson

Graduate Theses and Dissertations

I develop a theory of personal ontology called normative pragmatic selfhood (NPS) to explain what persons are and how they are morally valuable. I also demonstrate the applicability of NPS theory by using it to assess the moral status of marginal cases in bioethical dilemmas. I begin by discussing the concept of intrinsic value and why it is problematic when it comes to persons. I then draw upon John Dewey’s theory of value, specifically the concept of growth, and Kant’s concept of humanity to show that persons are objectively yet extrinsically valuable. Next, I discuss and argue how the psychological …

The Transcriptome Of The Veiled Chameleon (Chamaeleo Calyptratus): A Resource For Studying The Evolution And Development Of Vertebrates, Brendan John Pinto, Daren C. Card, Todd A. Castoe, Raul E. Diaz Jr., Stuart V. Nielsen, Paul A. Trainor, Tony Gamble

Biological Sciences Faculty Research and Publications

Purpose

The veiled chameleon (Chamaeleo calyptratus) is an emerging model system for studying functional morphology and evolutionary developmental biology (evo‐devo). Chameleons possess body plans that are highly adapted to an arboreal life style, featuring laterally compressed bodies, split hands/ft for grasping, a projectile tongue, turreted independently moving eyes, and a prehensile tail. Despite being one of the most phenotypically divergent clades of tetrapods, genomic resources for chameleons are severely lacking.

Methods

To address this lack of resources, we used RNAseq to generate 288 million raw Illumina sequence reads from four adult tissues (male and female eyes and gonads) …
