Manchester Snow Emergency Analysis: Who Is Being Towed From Where And Why, Michael James Pelletier

Master's Theses and Capstones

This Capstone paper analyzes the City of Manchester, New Hampshire’s policy and community impacts when their Towing Snow Emergency procedures are implemented. While the public expects their city streets and sidewalks to be cleared of snow during and following snow storms, the process to do so in the city streets requires vehicles to be re-located from parking on the street. This process requires privately owned vehicles to be ticketed or towed during the worst of weather during the winter. Although the city administration has attempted to avoid having to tow vehicles as the report shows, there is still a historical …

High-Frequency Broadband Seafloor Backscatter In A Sandy Estuarine Environment, Eric J. Bajor

Master's Theses and Capstones

Seafloor backscatter collected with high-frequency (> 100 kHz) hydrographic echosounders has become an important aspect of seafloor characterization for benthic ecologists and other scientists. The mechanisms that control acoustic scattering at these high frequencies are not completely understood, although surficial roughness and the presence of discrete particles (e.g., shell hash) are likely contributors. To further our understanding of the impact these mechanisms have on seafloor scattering, broadband (100-250 kHz) acoustic measurements were taken at a grazing angle of 45° in a shallow-water, sandy environment with a known presence of shell hash. Stereo imagery was collected simultaneously to quantify the surficial …

Law, Justice, And All That Jazz: An Analysis Of Law's Reach Into Musical Theater, Amy Oldenquist

Master's Theses and Capstones

Narratives or stories are present in many facets of life. Narratives especially are seen in the media, fiction and nonfiction alike. These stories, seen in media, fiction, and nonfiction alike, have an immense impact on their audience. This influence displays the importance of continued research into media’s narratives, especially legal narratives. Much of past research looked at the social construction of these stories and its framing. Framing refers to how a subject is discussed in the media. While there is much research on media, framing, and legal narratives, very few researchers have examined live entertainment, including musical theater. My study …

Quantifying Glacier Sensitivity To Late Glacial And Holocene Climate Changes In The Southern Peruvian Andes, Elizabeth Grace Huss

Master's Theses and Capstones

Tropical glaciers are highly sensitive to small-amplitude climate changes, implying that paleoglacier positions are valuable proxies for reconstructing paleoclimate conditions. However, it is still unknown how glaciers in different regions along the Andes responded to changes in specific climate parameters, and in particular, to changes in the dominating influences of temperature and precipitation. To identify the dominant controls on tropical paleoglacier mass balance, a surface energy balance model (SEBM), coupled with an ice dynamics model, was applied to three valleys in the Cordillera Vilcabamba of southern Peru. These valleys contain present-day glaciers and preserve evidence for the areal extents and …

The test embankment was built with variable drain spacing and embankment geometry in order to determine effective and efficient treatment for long term ground settlement. Findings from this study are to be implemented in future applications in the New Hampshire seacoast where soft marine clay is present. Using data collected from several in situ and laboratory tests, this thesis investigates the use of finite element analysis to predict total settlement and time rate of consolidation …

Effects Of Substrate Material On Marine Fouling Community Composition And Ascidian Larval Settlement, Anna Lindsey Chase

Master's Theses and Capstones

Driven by the rising global population and shoreline development, man-made marine structures are becoming ubiquitous in coastal areas. These alterations may have enormous ecological consequences, as anthropogenic structures provide novel habitat for marine organisms and often host communities that differ from those on natural substrates. These community differences are frequently driven by non-native species, which can be more prevalent on man-made marine structures than on adjacent natural surfaces. Although multiple factors, including light intensity, surface orientation, predation exposure, and habitat type, are known to contribute to these patterns, relatively few studies have directly examined the influence of substrate material on …

The Effects Of Temperature On Cyp19a1a, Foxl2, Dmrt1 And Amh Expression During Sex Differentiation In Summer Flounder (Paralichthys Dentatus), Catherine Curro Caruso

Master's Theses and Capstones

Female summer flounder grow considerably faster and larger than males, and a tremendous increase in performance can therefore be realized through production of monosex female populations. Rearing temperature has been shown to affect sex differentiation in other teleost species by influencing expression of genes encoding transcription factors, hormones or enzymes involved in endocrine function such as cyp19a1a, foxl2, dmrt1 and amh. These genes have been linked to female (cyp19a1a, foxl2) or male (dmrt1, amh) development, and exhibit sexually dimorphic expression in some species. In the present study, summer flounder (37 days post hatch; DPH) were raised at 13°C, 16°C or …

Creating A Smartphone Application For Measuring Responses Of An Experimental Structure At Multiple Locations And For K-12 Stem Outreach Related To Structural Engineering, Kyle David Wyatt

Master's Theses and Capstones

Structural health monitoring (SHM) systems are used to measure and analyze structure data (e.g., floor accelerations and strains in structural members) to identify damage (or structural changes) to a structure. With aging infrastructures and collapses of recent structures such as the 2007 I-35W Mississippi River Bridge and the 2013 clothing factory in Bangladesh, SHM can help address an important societal issue in structural safety and reliability. In the current practice, SHM systems include dedicated sensors linked (via wires or wirelessly) to data acquisition systems. These sensing systems are typically costly and impractical for many educational curriculums. A lack of exposures …

Invasive Plant (Alliaria Petiolata; Garlic Mustard) Homogenizes Fungal Communtiy Composition And Increases Fungal Richness, Mark Anthony

Master's Theses and Capstones

Non-native invasive plants can disrupt native plant communities and soil function (e.g., C and N cycling), but few studies have examined how soil microbial community structure differs in association with invasion. This work focused on Alliaria petiolata (garlic mustard), a non-mycorrhizal Brassicaceae that can displace native plants and reduce aboveground diversity. Garlic mustard produces toxic phytochemicals that can suppress mycorrhizal fungi, but we currently do not know if garlic mustard invasion affects the general fungal community, including specific mycorrhizal fungi, saprotrophic fungi, and plant pathogens and parasites. The objective of this work was to compare uninvaded and invaded soils from …

Molecular Dynamics Studies Of Nucleic Acids And Ribonucleoprotein Complexes, Tyler James Mulligan

Master's Theses and Capstones

Molecular simulations of protein-nucleic acid complexes, as well as the HIV-1 Trans Activation Response Element (TAR) RNA molecule, were conducted. First, three different molecular dynamics techniques were studied on the molecule HIV-1 TAR RNA. The three techniques studied were classical molecular dynamics, steered molecular dynamics (SMD), and metadynamics. The classic molecular dynamics simulations were used to equilibrate the HIV-1 TAR RNA system, as well as every other system studied in this thesis. The SMD technique was used in order to observe the breaking force of the nucleotide interactions within TAR. This breaking force averaged to about 100pN. The metadynamics technique …

Establishment Of The Multicolored Asian Lady Beetle, Harmonia Axyridis, As A Model System For The Evolution Of Phenotypic Variation, Lindsay Havens

Master's Theses and Capstones

The mechanisms behind the evolution and maintenance of striking visual phenotypes are as varied as the species that display these phenotypes. Multiple study systems have been well characterized and provide critical information about the evolution of these traits. However, new study systems in which the phenotype of interest can be easily manipulated and quantified are essential to answer many questions about the functionality of core evolutionary processes. One such model is elytral spot number of the multicolored Asian lady beetle, Harmonia axyridis (Chapter 1). I describe Harmonia axyridis as a potential novel model species for examining extreme phenotypic evolution. To …

Implementing A Checklist & Hourly Huddles To Increase Situational Awareness During The Second Stage Of Labor-A Perinatal Quality Improvement Project, Kelly Knowles

Master's Theses and Capstones

Background: Current management of the second stage of labor often follows tradition-based routines rather than evidence-based practices. A lack of situational awareness and tunnel vision can limit medical decision-making. Northern New England Perinatal Quality Improvement Network (NNEPQIN) has listed Second Stage Situational Awareness as a priority initiative. Standardized checklists are useful for maintaining situational awareness. Regular debriefings using a standardized tool have been shown to improve communication and team based care, which generally leads to improved patient outcomes. Based on this evidence, developing a standardized checklist including regular hourly care team “huddles” is valuable and could result in improved birth …

The underlying mechanisms driving the coupled interaction of organic matter quantity and uptake of inorganic nitrogen are not well understood, particularly in surface waters. To determine the relationship between background dissolved organic carbon (DOC) quantity and nitrate (NO3-) uptake kinetics in streams, a series of NO3- TASCC additions were performed in four sites within the Lamprey River Watershed, New Hampshire, with a wide range in background DOC concentrations (1 mg C/L - 8 mg C/L). Experiments were performed between the 2013 and 2014 growing seasons. Across all sites and experimental dates, ambient and dynamic uptake velocity (Vf) correlated negatively with …

Effect Of In Vivo Polybrominated Diphenyl Ether (Pbde) Treatment On Hepatic Glyceroneogenesis And Lipid Metabolism, Kylie Rose Cowens

Master's Theses and Capstones

Polybrominated diphenyl ethers (PBDEs) are flame-retardant chemicals that contaminate the environment. Through ingestion and inhalation, these chemicals get into the human body, where they affect the liver by suppressing the metabolic enzyme phosphoenolpyruvate carboxykinase (PEPCK), which is partially responsible for glyceride-glycerol production via glyceroneogenesis. This study investigated the effects of PBDE-induced hepatic PEPCK suppression on glyceroneogenesis, and the associated perturbations in liver lipid metabolism. Twenty-eight male, weanling Wistar rats were treated daily with 14 mg/kg body weight PBDE mixture, DE-71 (TRT, n=14) or corn oil vehicle (CON, n=14) for 28 days. After a 48-hour fast, rats were sacrificed and blood …

The Benefits Of Recreational Fishing In Adolescence, Sarah Elaine Leonard

Master's Theses and Capstones

Little attention has been given to how different leisure activities affect adolescents. The purpose of this study therefore was to investigate how one specific leisure activity, recreational fishing, can provide potential benefits to adolescents. Youth attending a one week fishing camp at the 4-H Barry Conservation Camp in July of 2014 were surveyed on multiple dimensions of well-being. Results indicate significant improvements in resilience, optimism, and self-esteem following the fishing camp experience. Youth reported that while fishing they engaged in a number of skillful activities (patience, self-discipline, etc.), many of which are beneficial to the positive development of youth. The …

A sample of campers (n= 189) between the ages of 8-15 participated (mean age = 11.9 years old). A modified version of Guilford’s Alternate Uses Task (1967) was used for both pre and post-tests. Examples of questions asked were: “Name all the uses for a plate” and “Name all the uses for a brick”. Campers took the divergent thinking pre test the first full day of camp and the post test was administered on the last full day of camp. Paired t-tests …

Unique Features Of Identity Development In Transnational Adoptions, Minori Haga Stefon

Master's Theses and Capstones

Identity formation has been defined as the process by which an individual develops a coherent self-definition of one’s uniqueness (Erikson, 1968). Arnett (2000; 2014) proposed the concept of emerging adulthood (between ages 18 and 29) as the developmental stage of later adolescence at which an individual is both cognitively and psychologically best suited for identity formation. Emerging adults who had been adopted transnationally as children often struggle to articulate their ethnic identity as a dimension of their broader individual identity (Schwartz et al., 2013) because they have characteristics that do not fit into those of the majority (Adams & Marshall, …

A Coplanar Edge-Fed Optically-Transparent Microstrip Patch Antenna Operating In The 5-6 Ghz Frequency Spectrum, Eric Escobar

As wireless communications infiltrates our daily lives, there is a growing need for unobtrusive antennas. Utilizing optically transparent and electrically conductive material for antenna fabrication satisfies this demand. Optically transparent antennas have infiltrated applications in wireless communications where it is desired to reduce an antenna's visual or spatial impact. Their use in automotive applications preserves car aesthetics, while their integration onto solar cells of small satellites reduces size and thus weight. This work presents the development of a coplanar edge-fed optically transparent microstrip patch antenna, composed of highly conductive thin mesh wires designed to operate in the 5 to 6 …

Development Of A Biaxial Loading Frame For Thin Sheet Cruciform Specimens, Joseph Frederick Wilson

Master's Theses and Capstones

Characterization of the evolving yield loci and forming limit diagrams for sheet materials under biaxial loading is necessary for the development of accurate sheet metal forming process simulations. Biaxial tension testing has been shown to have significant advantages over the current computational and experimental methods for such material characterization; however, the few commercially available loading frames are far too large and expensive to be practical for most metal forming research laboratories. To address this problem, the University of New Hampshire’s Mechanics, Materials, and Manufacturing Lab is working to design a practical servohydraulic biaxial loading frame for such metal forming laboratories. …

Hardware Attack Detection And Prevention For Chip Security, Jaya Dofe

Master's Theses and Capstones

Hardware security is a serious emerging concern in chip designs and applications. Due to the globalization of the semiconductor design and fabrication process, integrated circuits (ICs, a.k.a. chips) are becoming increasingly vulnerable to passive and active hardware attacks. Passive attacks on chips result in secret information leaking while active attacks cause IC malfunction and catastrophic system failures. This thesis focuses on detection and prevention methods against active attacks, in particular, hardware Trojan (HT). Existing HT detection methods have limited capability to detect small-scale HTs and are further challenged by the increased process variation. We propose to use differential Cascade Voltage …
