Balancing Fracture And Fatigue Performance In Asphalt Pavements: A Hybrid Mechanistic And Statistical Modelling Approach, Danial Mirzaiyanrajeh Sep 2021

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, …


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 …


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 …

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. …


Microbiomes And Disease Suppressiveness Of Soils From Managed And Abandoned Orchards In New Hampshire, Madeleine Hassett Sep 2021

Microbiomes And Disease Suppressiveness Of Soils From Managed And Abandoned Orchards In New Hampshire, Madeleine Hassett

Master's Theses and Capstones

The soil microbiome is an essential component of ecosystem productivity. In agricultural systems, the soil microbiome significantly impacts plant health and the subsequent yield and productivity of those systems. Due to increasing demands on the food supply and the many challenges posed by climate change, soil fertility loss, and plant pathogens, modern agricultural systems often employ the use of chemical fertilizers and pesticides that can have detrimental effects on human health and the environment. These chemicals also significantly affect soil microbiomes, and although the extent of these effects are still unknown, changes in diversity or functionality of plant associated microbiomes …


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 …

Quantification Of Marine Acoustic Environments, Dylan Charles Wilford Sep 2021

Quantification Of Marine Acoustic Environments, Dylan Charles Wilford

Master's Theses and Capstones

The soundscape is an acoustic environment made up of all sounds arriving at a receiver. A methodology for the analysis of soundscapes was developed in an attempt to facilitate efficient and accurate soundscape comparisons across time and space. The methodology included generating and combining results from a collection of traditional soundscape metrics, statistical measures, and acoustic indices that were selected to quantify several salient properties of marine soundscapes: amplitude, impulsiveness, periodicity, and uniformity. The metrics were calculated using approximately 30 hours using semi-continuous passive acoustic data gathered in seven unique acoustic environments. The calculated values for each candidate metric were …


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 …

It is projected to face a decrease in production by as much as 50% by 2050, mainly due to rising temperature, changes in rainfall patterns, deforestation, and the spread of fungal pathogens and pests. Among the biological threats to coffee, the Coffee Leaf Rust (CLR) has the most destructive economic impact all around the world. The most recent widespread outbreak resulted in a 16% harvest loss in Central America and a 31% loss in Colombia during the 2012-2013 season, and a record of 50% loss was reported in Costa Rica …


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. Solute budgets for a portion of …

The Role Of Stat3 In Cisplatin Resistant Ovarian Cancer, Sarah Miseirvitch Sep 2021

The Role Of Stat3 In Cisplatin Resistant Ovarian Cancer, Sarah Miseirvitch

Master's Theses and Capstones

According to the American Cancer Society, approximately 21,410 women will receive a diagnosis of ovarian cancer, and 13,770 women will die from ovarian cancer in 2021. Typically, ovarian cancer is not diagnosed until it has reached stage III/IV in its progression. By later stages of disease, an ovarian cancer tumor has migrated to the peritoneum, existing either in single cell or spheroid form, and resulting in inflammation and buildup of ascites fluid, and metastasis of secondary tumors. Ascites fluid is comprised of many different secreted extracellular matrix (ECM) molecules, proteases and cytokines. The cytokine IL-6 is abundant in ascites fluid …


The Effect Of Wood-Fiber Substrates On Natural Disease Suppression And The Efficacy Of Rootshield®Wp Against Rhizoctonia Solani, Isobel Michaud Sep 2021

The Effect Of Wood-Fiber Substrates On Natural Disease Suppression And The Efficacy Of Rootshield®Wp Against Rhizoctonia Solani, Isobel Michaud

Master's Theses and Capstones

As by-products of the forest industry, wood fibers (WFs) are affordable and sustainable raw materials that have risen in popularity in the last decade to help meet the demand for soilless substrates. Wood fibers are high in hemicellulose and cellulose content yet have lower lignin content than Sphagnum peat, coconut coir, and tree bark-based growing medium components. Researchers have demonstrated that wood is more microbially active than peat and that WFs from pine and poplar have significantly greater fungal diversity and abundance than peat and coir, which can have higher bacterial diversity than WFs. However, the effects of WF-associated microbial …

Faculty Publications

Increasing climatic pressures such as drought and flooding challenge agricultural systems and their management globally. How agricultural soils respond to soil water extremes will influence biogeochemical cycles of carbon and nitrogen in these systems. We investigated the response of soils from long-term agricultural field sites under varying crop rotational complexity to either drought or flooding stress. Focusing on these contrasting stressors separately, we investigated soil heterotrophic respiration during single and repeated stress cycles in soils from four different sites along a precipitation gradient (Colorado, MAP 421 mm; South Dakota, MAP 580 mm; Michigan, MAP 893 mm; Maryland, MAP 1192 mm); …

Automatic Identification Of Internal Wave Characteristics Affecting Bathymetric Measurement Based On Multibeam Echosounder Water Column Data Analysis, Karolina Zwolak, Łukasz Marchel, Aileen Bohan, Masanao Sumiyoshi, Jaya Roperez, Artur Grządziel, Rochelle Ann Wigley, Sattiabaruth Seeboruth

Center for Coastal and Ocean Mapping

The accuracy of multibeam echosounder bathymetric measurement depends on the accuracy of the data of the sound speed layers within the water column. This is necessary for the correct modeling of ray bending. It is assumed that the sound speed layers are horizontal and static, according to the sound speed profile traditionally used in the depth calculation. In fact, the boundaries between varying water masses can be curved and oscillate. It is difficult to assess the parameters of these movements based on the sparse sampling of sound velocity profiles (SVP) collected through a survey; thus, alternative or augmented methods are …
