Item type:Item, Unfolding in One Breath: Exploring Free-form and Continuous Narratives in Violin Repertoire(2026) Liu, Yuan-ju; Salness, David; Music; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this dissertation is to provide further context for the three-recitalperformance project by Yuan-ju Liu, which examines single-movement violin repertoire. Titled Unfolding in One Breath, the project centers on violin works characterized by free-form narratives and continuous musical structures within a single-movement framework. The three themed performances—Poèmes and Ballades, Dramatic Monologues, Fantasies and Popular Sounds—each explore diverse violin repertoire while maintaining the unifying criterion of the single- movement form within the themes. This dissertation seeks to accomplish three main objectives. First, it aims to explore the evolving desire to experiment and adapt to modern culture and audience expectations, making classical programming accessible and relatable to the community. Second, it examines the historical and compositional backgrounds of each work, with particular attention to the influence of the composers’ creative processes. Third, it offers a performer’s perspective on preparation and interpretation of each performance and includes surveys gathered from audiences across the three performances. Video recordings for this dissertation can be accessed in the Digital Repository at the University of Maryland (DRUM).Item type:Item, HUNGARIAN AND KLEZMER MUSIC: FINDING FOLK ELEMENTS WITHIN THE CONTEMPORARY VIOLIN REPERTOIRE(2026) Kushubar, Zoe; Salness, David; Music; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Classical composers often utilize stylistic elements from folk music to create unique soundscapes in their music and/or affirm their cultural identity as artists within the realm of Western music. Some composers integrate folk melodies into their pieces while others write with particular elements of folk song and dance in mind, depending on their familiarity with the musical tradition. However, classical performers with Westernized conservatory training often lack the research background to determine how to identify these unique elements in classical music and how they relate to the original music traditions. Without the proper consultation of primary sources and field recordings, we may overlook and/or over-exoticize elements that serve an entirely different function in the music’s original context. And while most folk music was not originally intended to be shared in a concert hall, it is important to acknowledge the sociocultural and emotional context in which these pieces were written, especially when we find them in modern repertoire like that of Bartók and Bloch. For this dissertation project, I will prepare and present a series of three violin recitals featuring repertoire from Hungarian and klezmer or Jewish folk traditions. I chose these two musical idioms to examine potential geographical and cultural overlap, as these traditions have spread across central and Eastern Europe through Hungarian, Romani, and Jewish diasporas. In the first few chapters, I will provide general background on these folk musics in terms of style, general structure, and cultural function. In the later chapters, I will provide comprehensive overviews for each recital in terms of the following: 1) repertoire selection, 2) a historical, analytical, and interpretive overview of each piece, and 3) research and performance challenges.Item type:Item, The effects of land cover and climate change on wetness and runoff partitioning of small catchments(2026) Mullen, Jennie-Jin; Prestegaard, Karen; Geology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Climate change has altered precipitation patterns increasing annual precipitation and the frequency of short duration storms. In addition, urban areas have expanded altering the distribution and transport of water within a catchment. In this study, I examined temporal relationships in water balance components, focusing on inter-annual variations in runoff and wetness partitioning for 25 Maryland USGS gaged sites with varying urban, forest, and agricultural land cover. First, I quantified systematic inter-annual variations of baseflow and stormflow as a function of land use. Forested catchments exhibited the largest baseflow inter-annual variations, associated with variations in cold season precipitation. Urban catchments have lower inter-annual variations in baseflow due to limited infiltration caused by impervious cover. Next, I examined the response of groundwater and baseflow to the timing and magnitude of 2 precipitation inputs: 2012 Hurricane Sandy and 2018 wet year. These data indicate that both groundwater and baseflow in forested catchments respond directly to small, more frequent storms, but not large, isolated warm-season storms. Urban basins had reduced seasonal baseflow and groundwater cycles and were not responsive to either storm type. Groundwater and baseflow recharge were only present during the 2018 wet year, but in subsequent years, groundwater and baseflow peaks steadily declined although annual precipitation was near normal. The decline may reflect the shift in precipitation events to short duration, high magnitude storms suggesting that storm characteristics may affect groundwater recharge and stream baseflow.Item type:Item, COLLECTING WITH CARE: COLLABORATIVE COLLECTION STRATEGIES AND THE CRM CURATION CRISIS IN THE PACIFIC NORTHWEST(2026) Haddad, Jordan Leigh; Palus, Matthew M; Anthropology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Archaeological repositories face long-recognized pressures from the accumulation ofCRM-generated collections, including storage limitations, underprocessed materials, and longterm stewardship burdens. These pressures reflect not only logistical problems, but also inherited assumptions about archaeological objects as scientific data that should be collected and curated indefinitely. This thesis explores how preservation professionals view the feasibility and need for collaborative collection strategies, and whether they see them as a way to improve stewardship and address the curation crisis. The project draws on decolonizing, Indigenous, and community archaeologies to question archaeologists’ default authority over material culture. To assess professional perspectives, this study uses an exploratory survey of preservation professionals regarding collaborative collection strategies, no-collection approaches, selective retention, and perceived feasibility. The project initially aimed for national reach but ended up being framed within the Pacific Northwest. Responses suggest that collaborative collection strategies are needed in the field of CRM and may help address the curation crisis through better stewardship, though the specifics of collection policies will need to be addressed on a project-by-project basis. The thesis contributes to CRM practice by reframing collection policies as early-stage stewardship tools rather than after-the-fact repository problems.Item type:Item, 3D-PRINTED MICROFLUIDIC CAPILLARIC CIRCUITS FOR THE AUTOMATION OF RADIOPHARMACEUTICAL SYNTHESIS(2026) Rosser, Mark Alexander; Sochol, Ryan D.; Mechanical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Positron emission tomography (PET) offers a powerful means of tracking transplantedmesenchymal stem cells in vivo, but the radiopharmaceuticals required for PET-based tracking, such as [89Zr]Zr-SCN-Bn-DFO, are currently synthesized and handled manually. This manual process exposes laboratory personnel to prolonged, close-proximity radiation during pipetting, mixing, and incubation, approaching regulatory dose limits under ALARA guidelines. This thesis presents the design, fabrication, and experimental validation of a novel capillaric microfluidic circuit platform for autonomous, pump-free radiopharmaceutical synthesis, distinguished from prior sequential-release, absorption-based capillary circuit systems by its simultaneous-release, product-recovery architecture. Two capillaric chip designs, Chip 1 and Chip 2, were developed and independently fabricated for two fluid systems, fluorescent surrogate dyes and radioactive synthesis reagents, yielding four unique chip geometries validated across this work. Chip geometries were derived from governing capillary pressure, hydraulic resistance, and diffusion-based mixing equations, using fluid properties obtained from literature and, where unavailable, experimentally back-calculated using the chips themselves as tensiometers. Chips were fabricated via LCD-based vat photopolymerization on an Elegoo Mars 5 printer using biocompatible Liqcreate Bio-Med Clear resin, with fabrication accuracy validated through SEMbased feature characterization and surface wettability confirmed through contact angle measurements following oxygen plasma treatment and Pluronic F-108 functionalization. Chip performance was first validated using fluorescent surrogate fluids, confirming simultaneous reservoir release and diffusion-driven mixing via fluorescence imaging. Radioactive synthesis was subsequently evaluated across four test sessions alongside conventional cuvette controls. In final testing, the chip platform achieved radiolabeling efficiencies exceeding 94% within 5 minutes, compared to 20 minutes required by the cuvette method to reach comparable efficiency, a fourfold reduction in synthesis time. MSC labeling was additionally demonstrated with cell viability comparable to unlabeled controls, confirming the biocompatibility of the platform and its potential to substantially reduce radiation exposure while maintaining clinically relevant synthesis performance.
