Isotopic Evidence For Dominant Secondary Production Of Hono In Near-Ground Wildfire Plumes, Jiajue Chai, Jack E. Dibb, Bruce E. Anderson, Claire Bekker, Danielle E. Blum, Eric Heim, Carolyn E. Jordan, Emily E. Joyce, Jackson H. Kaspari, Hannah Munro, Wendell W. Walters, Meredith G. Hastings

Faculty Publications

Nitrous acid (HONO) is an important precursor to hydroxyl radical (OH) that determines atmospheric oxidative capacity and thus impacts climate and air quality. Wildfire is not only a major direct source of HONO, it also results in highly polluted conditions that favor the heterogeneous formation of HONO from nitrogen oxides (NOx= NO + NO2) and nitrate on both ground and particle surfaces. However, these processes remain poorly constrained. To quantitatively constrain the HONO budget under various fire and/or smoke conditions, we combine a unique dataset of field concentrations and isotopic ratios (15N / 14N and 18O / 16O) of NOx …

Sediment Transport And The Temporal Stability Of The Seafloor In The Hampton-Seabrook Estuary, Nh: A Numerical Model Study, Katherine Vera Von Krusenstiern

Master's Theses and Capstones

Observations of sediment transport pathways and bathymetric change are often difficult to obtain over spatial and temporal scales needed to maintain economic and ecological viability in dynamic coastal and estuarine environments. As a consequence, numerical models have become a useful tool to examine the sediment transport and evolution of inlets, estuaries, and harbors. In this work, sediment transport at the Hampton-Seabrook Estuary (HSE) in southern New Hampshire is simulated using the Coupled Ocean Atmospheric Waves and Sediment Transport (COAWST) modeling framework to assess bathymetric change over a 5-year period from September 2011 to November 2016. Initial bathymetry and sediment grain …

Altered Alpha Oscillatory Power Dynamics Underlie Difficulties With Cognitive Flexibility, Nicole Forner

Doctoral Dissertations

Cognitive flexibility is an important mental faculty, but there are certain populations that experience reduced flexibility, which may be associated with altered neural activity. Rumination is when an individual becomes mentally stuck on a thought, and they experience difficulty shifting their attention away from the ruminative thought demonstrating reduced cognitive flexibility. In a similar manner, individuals diagnosed with substance use disorder show varying degrees of attentional bias towards drug related stimuli. The drug cues capture attention, and it is difficult for these individuals to shift attention away from thoughts related to drug cues. Both populations experience difficulty shifting attention when …

Transport, Species-Specific Resource Competition, And Shallow Water Effects In Coupled Bio-Physical Ecosystem Models For C. Polykrikoides Harmful Algal Blooms Off The Coast Of Korea, Jang-Geun Choi

Doctoral Dissertations

This thesis examines the role of transport and environmental variables in determining the occurrence or suppression of harmful algal blooms (HABs). In the first part, a simple 2-D diagnostic model is used to hindcast HABs occurring off the coast of Korea using observations of averaged environmental factors including nutrient concentration. Hindcasting results using the model show that physical transport of HABs is of the same order of importance as the environmental conditions in controlling HABs. The model reproduces the interannual variability of the observe HABs off the coast of Korea. The relative importance of the environmental factors based on limiting …

On The Images Of Braid Group Representations Coming From Braided Fusion Categories, Jason Allen Green

Doctoral Dissertations

Braided fusion categories are algebraic structures with strong ties to the representation theory of finite groups, Hopf algebras, and quantum groups. These structures also have strong connections with braid groups and low-dimensional topology. Recently, braid group representations coming from braided fusion categories have become a topic of interest in areas of condensed matter physics and topological quantum computation. Particularly interesting are the properties of the images of these representations.

Calculations to determine the finiteness of these images have been performed for a few cases. A class of braided fusion categories coming from finite groups (group-theoretical) has been shown to yield …

Cover Crop-Based No-Till For Small Farms: Tradeoffs Of Termination Time, Method, And Ecosystem Services, Natalie Lounsbury

Doctoral Dissertations

Agriculture must adapt to and mitigate multiple environmental crises including climate change, overuse of herbicides, and soil degradation. Cover crops are a promising tool to do so because they protect soil from erosion, increase perenniality (i.e. year-round plant cover) and carbon contributions to farming systems, capture, recycle, and fix nitrogen, and suppress weeds through multiple mechanisms. Terminating high-residue cover crops to produce an in situ mulch for no-till production has added benefits of eliminating the need for tillage, protecting soil against extreme precipitation events and drought, and contributing to weed suppression. However, there are few non-chemical ways to terminate cover …

Path Components And Elementary Orbits Of Um(2,R), Timothy A. Fill

Doctoral Dissertations

For any commutative ring R with identity, Um(2, R) is the set of all vectors α ∈ R^2 such that α^T β = 1 for some β ∈ R^2. Motivated by Hinson and Samuel, we endow Um(2, R) with a pseudo-graph structure and introduce a family of functions on the general ring R defined in terms of graph theoretic distance from a designated base-point or base-set. We propose a particular connected base-set whose quasi-Euclidean function exhibits the most computationally convenient properties. Unlike in Um(n, R), n ≥ 3, the relationship between path components of Um(2, R) and its orbits under …

Merging Ecology And Earth System Modeling: Biotic And Abiotic Controls Drive Soil Carbon And Nitrogen Cycling In Microbial-Explicit Soil Biogeochemistry Models, Emily Kyker-Snowman

Doctoral Dissertations

Ecological processes drive terrestrial biogeochemistry, yet the incorporation of ecology into the Earth system models that we use to understand and project global change remains. My dissertation focuses on expediting the incorporation of ecology into Earth system models, first by laying out a roadmap from initial assessment of ecological insights to eventual ESM incorporation, and then by demonstrating this roadmap using the example of microbially- controlled carbon and nitrogen cycling in soil. The paradigm around SOM formation and loss has shifted in recent decades away from a focus on the chemically recalcitrant leftovers of litter decomposition and towards a paradigm …

The Dissemination And Reproduction Of Dominant Ideologies On Social Media: Reddit Through The Lens Of Color-Blind Racism And Gender-Blind Sexism, Paul Anskat

Doctoral Dissertations

This dissertation explores the frameworks of color-blind racism and gender-blind sexism as they are disseminated through the social media site Reddit. I analyze data in the form of posts and comments submitted to the site. Qualitative discourse analysis reveals employment of the frames of color-blindness and gender-blindness as well as narratives which function to anchor the dominant ideologies to apparent lived experiences. This dissertation offers two major contributions to the scholarship of racism and sexism. First, the findings demonstrate that ideologies of race and gender are often articulated through common narratives and intertwined rhetoric, establishing a foundation for future research …

The Influence Of Third Parties, Perfectionism, And Familial Socioeconomic Status On College Student Mental Health And Perceptions Of Social Support, Amanda Fontaine

Doctoral Dissertations

Mental health has long been a fruitful area of sociological inquiry, and much remains to be illuminated about the ways in which the social context and intrapersonal factors intersect to impact individuals’ psychological wellbeing. Among college students particularly, stresses such as academic pressure and interpersonal conflicts contribute to the degradation of mental health. While sociological theories such as the stress process perspective have long been employed to study linkages between stress and mental wellbeing among this population, few studies have examined the specific characteristics of social relationships most beneficial to students in distress. Utilizing survey responses collected from both public …

Seneca, The Humors, And Revenge Tragedy, Andrew Stesienko

Doctoral Dissertations

This dissertation argues that moral and religious authorities of the Elizabethan and Jacobean periods adapted rules for emotional governance from Senecan philosophy. These Senecan rules helped institute a performance-based approach to managing emotion, which relied on programmatic meditation, rhetoric, and behavior to change one’s emotional state. This approach ostensibly offered more personal control over affective inclination, which according to the period’s Galenic paradigms, was heavily influenced by environmental and physiological factors. My project examines revenge tragedy to highlight Senecan-inspired affect management as practiced by aspiring avengers. Because revenging hopefuls must amplify and then mobilize their feelings in order to achieve …

Alkalinity And Buffering In Estuarine, Coastal And Shelf Waters, Christopher Hunt

Doctoral Dissertations

As anthropogenic climate change continues to elevate the amount of carbon dioxide (CO2) in the Earth’s atmosphere, the absorption of a large portion of this CO2 by Earth’s oceans has resulted in a steady decrease in pH. The consequent phenomenon of ocean acidification (OA) is a result of shifts in the carbonate chemistry system of the ocean- a system which can be analytically described by several factors, including total alkalinity (TA). TA in the oceans has been measured for over a century, but analytical and operational constraints have limited these measurements in time and space. Additionally, recent work has highlighted …

Balancing Fracture And Fatigue Performance In Asphalt Pavements: A Hybrid Mechanistic And Statistical Modelling Approach, Danial Mirzaiyanrajeh

Doctoral Dissertations

The asphalt mix design and evaluation approaches are divided into two main categories as empirical and mechanistic-empirical (M-E) methods. The empirical methods are based on empirical observations of in-service pavement performance, and they do not take into account engineering properties or failure criteria. The M-E methods were introduced as a new generation for design and evaluation approaches that consider fundamental mixture properties such as material stiffness to determine the pavement's structural response. However, the need for expensive and time-consuming performance-based laboratory tests and local calibration makes the M-E methods unsuitable for routing design. In addition, during the last few years, …

Economics Of Pest Control And Pollination Conservation: Perspectives From A Bioeconomic Model And A Choice Experiment, Linghui Wu

Doctoral Dissertations

The first chapter focuses on the need to reduce pollinator exposure to harmful pesticides has led to calls to expedite theadoption of integrated pest management (IPM). We make the case that IPM is not explicitly 'pollinator friendly', but rather must be adapted to reduce impacts on pollinators and to facilitate synergies between crop pollination and pest control practices and ecosystem services. To reconcile these diverse needs, we introduce a systematic framework for 'integrated pest and pollinator management' (IPPM). We also highlight novel tools to unify monitoring and economic decision-making processes for IPPM and outline key policy actions and knowledge gaps. …

Laboratory And Computational Mechanics-Based Framework For The Analysis And Design Of Cold Recycled Pavement Layers, Francesco Preti

Doctoral Dissertations

Cold recycling technologies are becoming increasingly popular for rehabilitation of asphalt pavements. These technologies allow construction of new pavement layers with minimal addition of heat and minimal need for transporting the material. In fact, Cold Recycled Mixtures (CRM) can be prepared in mobile plants or directly in place while using up to 100% of the milled material from an existing asphalt pavement (Reclaimed Asphalt Pavement or RAP) and without the need of heating up the aggregates. The products obtained through the use of cold recycling technologies are also commonly called Bituminous Stabilized Materials (BSM). BSM are considered to be partially-bonded …

Learning To Act With Robustness, Reazul Hasan Russel

Doctoral Dissertations

Reinforcement Learning (RL) is learning to act in different situations to maximize a numerical reward signal. The most common approach of formalizing RL is to use the frameworkof optimal control in an inadequately known Markov Decision Process (MDP). Traditional approaches toward solving RL problems build on two common assumptions: i) exploration is allowed for the purpose of learning the MDP model and ii) optimizing for the expected objective is sufficient. These assumptions comfortably hold for many simulated domains like games (e.g. Atari, Go), but are not sufficient for many real-world problems. Consider for example the domain of precision medicine for …

Self Defense And Sea Power: The Provincial Navies Of The British Atlantic World, 1689-1763, Benjamin Cameron Schaffer

Doctoral Dissertations

“Self Defense and Sea Power: The Provincial Navies of the British Atlantic World, 1689-1763,” explores the ways in which Anglo-American colonial governments in North America and the West Indies managed naval defense during imperial and border conflicts between the late seventeenth and mid-eighteenth centuries. With limited military assistance from the imperial government in London, provincial leaders built their own semi-permanent and temporary navies to protect commerce from Franco-Spanish privateers, pirates, and Native American naval forces. Provincial governments also utilized these fleets to spearhead sieges of enemy ports, support infantry operations on land, and to transport troops and supplies to warzones. …

Mechanistic Modelling Framework And Life Cycle Assessment Approach For Pavement Rehabilitation Using Asphalt Concrete Overlays, Katie Eileen Haslett

Doctoral Dissertations

Efficient and effective rehabilitation of existing roadways continues to be a top priority for local, state, and federal agencies to provide safe travel of people and goods. Asphalt concrete (AC) overlays on deteriorated Portland Cement Concrete (PCC) are a popular rehabilitation option to extend the service life of a roadway. However, the combination of load and environmentally induced movements at underlying joint locations can cause high amounts of stresses and strains, leading to the formation of cracks in the AC overlay. Ensuring that a suitable asphalt mixture (cracking resistance) and sufficient overlay structure (thickness) are selected is critical to avoid …

A Comprehensive Study Of The Hardware Trojan And Side-Channel Attacks In Three-Dimensional (3d) Integrated Circuits (Ics), Zhiming Zhang

Doctoral Dissertations

Three-dimensional (3D) integration is emerging as promising techniques for high-performance and low-power integrated circuit (IC, a.k.a. chip) design. As 3D chips require more manufacturing phases than conventional planar ICs, more fabrication foundries are involved in the supply chain of 3D ICs. Due to the globalized semiconductor business model, the extended IC supply chain could incur more security challenges on maintaining the integrity, confidentiality, and reliability of integrated circuits and systems. In this work, we analyze the potential security threats induced by the integration techniques for 3D ICs and propose effective attack detection and mitigation methods. More specifically, we first propose …

Repeatfs: A File System Providing Reproducibility Through Provenance And Automation, Anthony Stephen Westbrook

Doctoral Dissertations

Reproducibility is of central importance to the scientific process. The difficulty of consistently replicating and verifying experimental results is magnified in the era of big data, in which computational analysis often involves complex multi-application pipelines operating on terabytes of data. These processes result in thousands of possible permutations of data preparation steps, software versions, and command-line arguments. Existing reproducibility frameworks are cumbersome and involve redesigning computational methods. To address these issues, we developed two conceptual models and implemented them through RepeatFS, a file system that records, replicates, and verifies computational workflows with no alteration to the original methods. RepeatFS also …

Study Of Primary Cilia In Early Development, Pharmacology, And Brainwave Activity., Matthew Roderick Strobel

Doctoral Dissertations

The primary cilium is a unique cellular organelle that emanates from the mother centriole and extends out of the plasma membrane of nearly every mammalian cell. While originally believed to be a vestigial appendage, the cilium is now known to be a signaling hub where various intercellular communication pathways intersect to regulate morphogenesis, proliferation, polarity, differentiation, and homeostasis. Due to their importance in regulating cellular functions the cilium has become a growing focus of biomedical research as it has been linked to at least 35 human developmental disorders which have been termed ciliopathies. In the nervous system, primary cilia regulate …

The Propagation And Evolution Of Coronal Mass Ejection Driven Sheath Regions: Insight From Multi-Spacecraft Measurements And Statistical Approaches, Tarik Mohammad Salman

Doctoral Dissertations

The complexities of our nearest star, the Sun, are characterized by its magnetic field. In the absence of a magnetic field, diverse phenomena as the solar cycle, solar eruptions, solar wind, to name but a few, would be unknown to us. Coronal mass ejections, a large form of solar eruption, are an essential mechanism for the evolution of the Sun. CMEs provide a means by which the built-up magnetic flux and solar material over solar cycles are removed from the solar atmosphere into the solar wind. This spectacular phenomenon has repercussions throughout the heliosphere, driving a range of heliospheric, magnetospheric, …

Distribution Of Soil Enzyme Activity Across Soil Organic Matter Fractions: A Meta-Analysis, Christina Lyons

Master's Theses and Capstones

Enzymes are the drivers of organic matter degradation and biogeochemical cycling. Extracellular enzyme activity is often examined on a bulk soil level though some studies explore their activity within soil fractions. Across soil size fractions, organic matter turnover differs greatly suggesting that enzymes are either unevenly distributed across fractions or their activity or efficacy is concentrated in certain fractions, likely those with the greatest quantities of organic matter. By examining the distribution of soil enzyme activity across different size fractions, we can better understand the relative role individual particles and aggregate building blocks have on enzyme activity, and also the …

"It's Not Just Sailors And Bikers Anymore": How Tattoo Artists' Experiences Of Stigma Vary By Gender, Morgan Stevens

Master's Theses and Capstones

Past literature has largely focused on the stigmatization of those with tattoos, but the experiences of tattoo artists themselves have largely been overlooked. It is important to focus on tattoo artists given their critical position as the subjects of stigma and their role in challenging it. Tattoo artists are privy to their own experiences with tattoo stigma, the stigma of working in a deviant occupation, and are frequent observers of the stigma others experience for similar reasons. To explore these topics and how the occupation itself is gendered, thirteen semi-structured interviews were conducted with tattoo artists in New Hampshire. From …
