Repeatfs: A File System Providing Reproducibility Through Provenance And Automation, Anthony Stephen Westbrook Sep 2021

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 Sep 2021

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 Sep 2021

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 Sep 2021

"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 …

Condors And Capitalism: Changing Interactions Between Presidents And Indigenous Movements In The 21st Century In Ecuador, Bolivia And Peru., Heather E. Austin Sep 2021

Condors And Capitalism: Changing Interactions Between Presidents And Indigenous Movements In The 21st Century In Ecuador, Bolivia And Peru., Heather E. Austin

Master's Theses and Capstones

Indigenous social movements began proliferating across Latin America in the late 20th century. Since then, scholars have focused analyses on the factors shaping indigenous movement-state dynamics, with little consideration for how these interactions impact the larger indigenous population. This work addresses the question of how changing indigenous movement-presidential relationships affect indigenous political attitudes and behavior in Ecuador, Bolivia and Peru, qualitatively using comparative historical analysis, and quantitatively using binomial logistical and ordinal logistical regressions. I conclude first that the inclusion of indigenous movements represents a democratic deepening, but has a destabilizing effect, as the system must expand and adapt to …

The Presence Of Sea Lice On Steelhead Trout At A Marine Farm In Nh Waters And The Utilization Of Lumpfish As A Biological Delouser, Michael Brian Doherty Sep 2021

The Presence Of Sea Lice On Steelhead Trout At A Marine Farm In Nh Waters And The Utilization Of Lumpfish As A Biological Delouser, Michael Brian Doherty

Master's Theses and Capstones

Sea lice are copepodid ectoparasites that infect fish, and cost salmonid farmers millions of dollars each year in damaged product and mitigation efforts. Conventional treatments can unintentionally impact the ambient environment and lead to the lice developing resistance to the treatments. In recent years, lumpfish (Cyclopterus lumpus) have been utilized successfully to naturally clean sea lice from infected salmonids in European and Atlantic Canadian farms, however this technology has yet to be used in US farms. In New Hampshire coastal waters, New Hampshire Sea Grant and the University of New Hampshire operate an experimental steelhead trout (Oncorhynchus mykiss) farm, AquaFort. …

Seasonal Feeding And Movement Responses Of Resident Sculpin In The Canadian Arctic, Nathan Thomas Hermann Sep 2021

Seasonal Feeding And Movement Responses Of Resident Sculpin In The Canadian Arctic, Nathan Thomas Hermann

Master's Theses and Capstones

Environments change across space and time, requiring organisms to adapt behaviorally and/or physiologically. In the Arctic, where productivity varies greatly among seasons, many marine species exploit a resource pulse associated with annual ice melt. Melting sea-ice releases zooplankton on and within the ice into open water causing many consumers to migrate with the receding ice; however, resident species may too rely on the ephemeral prey source. Fourhorn Sculpin (Myoxocephalus quadricornis) and Slimy Sculpin (Cottus cognatus) are residents of Tremblay Sound, Nunavut Canada which is known as a seasonally productive system in the Arctic. I characterized the seasonal behavior of sculpin …

Short & Long-Term Restoration Dynamics Of Created Freshwater And Estuarine Wetlands, James Grant Mckown Sep 2021

Short & Long-Term Restoration Dynamics Of Created Freshwater And Estuarine Wetlands, James Grant Mckown

Master's Theses and Capstones

The restoration of tidal and freshwater wetlands either through compensatory mitigationor voluntary efforts have become a major strategy to conserve remaining wetland resources after historic losses and in the face of current unprecedented threats. Prior efforts of wetland restoration have often fallen short of expectations due to the reliance of a compliance success framework, which requires short monitoring timeframes, misapplies successional theories, and defines success of projects into a yes or no dichotomy. Decades of advancement in restoration ecology theory and its application to wetland ecology and botany have led to the development of a functional success framework to improve …

Master's Theses and Capstones

This research explores the effects of processing history and compressive strain on a microstructurally flexible high entropy alloy (HEA), Fe42Mn28Co10Cr15Si5 (in at%) – named DP-5Si-HEA. The material was characterized by electron backscatter diffraction (EBSD), scanning electron microscopy (SEM), and neutron diffraction. The as-rolled material had metastable gamma austenite (γ), stable sigma (σ), and stable epsilon martensite (ε) phases at room temperature. Friction stirrer processing (FSP) at different tool speeds changed the microstructure by decreasing the grain size and varying the phase fractions because of the low stacking fault energy of the chosen HEA. The HEA exhibited peak ultimate tensile strength …

Biogeochemical Stressors And Ecological Response In Great Bay Estuary, Nh/Me, Anna Lowien Sep 2021

Biogeochemical Stressors And Ecological Response In Great Bay Estuary, Nh/Me, Anna Lowien

Master's Theses and Capstones

Estuaries are threatened by eutrophication due to increasing anthropogenic nutrient loading from surrounding coastal watersheds. The Great Bay Estuary, NH/ME, has been designated as nitrogen impaired primarily due to a 44% loss in eelgrass coverage since 1996. Since 2014, wastewater treatment plants in the watershed have begun upgrading to reduce nitrogen loads to Great Bay. This region has also experienced changes in climate, with multiple, consecutive years of low annual precipitation totals. The loss of eelgrass, increased variability in precipitation, and continued anthropogenic land-use influence on the region have biogeochemical consequences for Great Bay.

Permeafor Testing Of Granular Soils, Alex Lefebvre Sep 2021

Permeafor Testing Of Granular Soils, Alex Lefebvre

Master's Theses and Capstones

There are currently several in situ and laboratory methods of determining hydraulic conductivity of soils, however, it remains a difficult parameter to obtain accurately and economically. Current laboratory tests are performed on soil specimens that are disturbed by the sampling process and only represent a portion of the overall site. Some in situ testing methods are also available such as the pump test but are expensive and provide an average value of conductivity for the site. As a result of this averaging, critical zones of high or low hydraulic conductivity in the profile could be missed and represented by a …

Coronal Hole Detection And Open Magnetic Flux, Jon A. Linker, Stephan G. Heinemann, Manuela Temmer, Mathew J. Owens, Ronald M. Caplan, Charles N. Arge, Eleanna Asvestari, Veronique Delouille, Cooper Downs, Stefan J. Hofmeister

Coronal Mass Ejection Research Group

Many scientists use coronal hole (CH) detections to infer open magnetic flux. Detection techniques differ in the areas that they assign as open, and may obtain different values for the open magnetic flux. We characterize the uncertainties of these methods, by applying six different detection methods to deduce the area and open flux of a near-disk center CH observed on 2010 September 19, and applying a single method to five different EUV filtergrams for this CH. Open flux was calculated using five different magnetic maps. The standard deviation (interpreted as the uncertainty) in the open flux estimate for this CH …
