The endothelium in the coronary arteries is subject to wall shear stress and vessel wall strain, which influences the biology of the arterial wall. This study presents vessel-specific fluid–structure interaction (FSI) models of three coronary arteries, using directly measured experimental geometries and boundary conditions. FSI models are used to provide a more physiologically complete representation of vessel biomechanics, and have been extended to include coronary bending to investigate its effect on shear and strain. FSI both without- and with-bending resulted in significant changes in all computed shear stress metrics compared to CFD (p = 0.0001). Inclusion of bending within …

Climate Change, Site Formation, And Indigenous Use Of Coastlines In Barbuda, Isabel C. Rivera-Collazo, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This article explores the landscape dynamics at the island of Barbuda in the context of changing climate to understand (1) the environmental setting of indigenous settlements; (2) the impacts of current coastal processes; and (3) the potential threats moving forward toward increasing pressure of climate change. Focusing on the site of Seaview, on the east coast of Barbuda, we use geoarchaeological methods to reconstruct the ancient geomorphological setting, investigate changes post-abandonment, and identify the hazards faced under future sea-level projections. Our study shows that (1) sea level stabilization after the Mid-Holocene allowed the formation of coral reefs, seagrass beds and …

Fusarium Species Structure In Nebraska Corn, Yuchu Ma

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Fusarium species are known to infect corn and cause significant yield losses and mycotoxin contamination worldwide. In this study, we investigated the diversity of Fusarium species infecting corn in Nebraska and their potential to produce fumonisins and trichothecenes. A total of 259 Fusarium isolates were collected from different corn tissues (ear, stalk, and root), revealing a significant association between the various Fusarium species complexes and different plant parts (p < 0.05). Fusarium incarnatum-equiseti species complex (FIESC) was the most widespread and abundant, followed by the Fusarium sambucinum (FSAMSC) and Fusarium fujikuroi species complexes (FFSC). In the subsequent analysis, we investigated the mycotoxin …

Crystalline–Amorphous Nanostructures: Microstructure, Property And Modelling, Binqiang Wei, Lin Li, Lin Shao, Jian Wang

Department of Mechanical and Materials Engineering: Faculty Publications

Crystalline metals generally exhibit good deformability but low strength and poor irradiation tolerance. Amorphous materials in general display poor deformability but high strength and good irradiation tolerance. Interestingly, refining characteristic size can enhance the flow strength of crystalline metals and the deformability of amorphous materials. Thus, crystalline–amorphous nanostructures can exhibit an enhanced strength and an improved plastic flow stability. In addition, high-density interfaces can trap radiation-induced defects and accommodate free volume fluctuation. In this article, we review crystalline–amorphous nanocomposites with characteristic microstructures including nanolaminates, core–shell microstructures, and crystalline/amorphous-based dual-phase nanocomposites. The focus is put on synthesis of characteristic microstructures, deformation …

Protease Inhibitor Asp Enhances Freezing Tolerance By Inhibiting Protein Degradation In Kumquat, Hua Yang, Ke-Wei Qiao, Jin-Jing Teng, Jia-Bei Chen, Ying-Li Zhong, Li-Qun Rao, Xing-Yao Xiong, Huang Li

Center for Plant Science Innovation: Faculty Publications

Cold acclimation is a complex biological process leading to the development of freezing tolerance in plants. In this study, we demonstrated that cold-induced expression of protease inhibitor FmASP in a Citrus-relative species kumquat [Fortunella margarita (Lour.) Swingle] contributes to its freezing tolerance by minimizing protein degradation. Firstly, we found that only cold-acclimated kumquat plants, despite extensive leaf cellular damage during freezing, were able to resume their normal growth upon stress relief. To dissect the impact of cold acclimation on this anti-freezing performance, we conducted protein abundance assays and quantitative proteomic analysis of kumquat leaves subjected to cold acclimation …

Blurred Lines: An Analysis Of Karel Husa's Music For Prague, 1968 Using Fuzzy Serialism, Sydney Wilson

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The wind band work Music for Prague, 1968 by Karel Husa is a well-respected work that has withstood the test of time. Husa, a native of then-Czechoslovakia, composed the piece in less than a year from the United States. The piece serves as a method of expressing his feelings regarding the invasion of his homeland where his family was still residing. Husa accomplished this expression through the use of a nationalistic theme, the Hussite War Song, and his own integration of twelve-tone serialism.

This study looks at pre-existing literature surrounding Husa’s use of serialism, including an analysis by Husa himself. …

Experimentation On Nebraska Farms For Sustaining Soil Health Management, Fernanda Souza Krupek

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Soil health management practices have increasingly been promoted across US agroecosystems to address many interrelated environmental and economic food system challenges. Sustaining conservation behavior – through farmer’s adoption and continued use of practices – is key for achieving many soil health-related intended social-ecological benefits. Using a range of scientific methods, from lab-based experiments to on-farm research to farmer interviews, the overall objective of this dissertation research was to explore soil and human dimension considerations to design farming and knowledge transfer systems for sustaining soil health management in the US Midwest. In a multivariate analysis of ten on-farm research sites, we …

“Evolving Homes, Not Revolving Doors”: Examining Lesbian, Gay, And Bisexual Foster Parents’ Discursive Construction And Negotiation Of Identity Layers And Identity Gaps, Lucas Hackenburg

Department of Communication Studies: Dissertations, Theses, and Student Research

The United States foster care system serves more than half a million children each year (U.S. Department of Health and Human Services [DHH], 2023). The purpose of this study was to examine how LGB foster parents discursively construct and navigate their identities in the fostering context. The researcher undertook in-depth interviews with 18 LGB people who were currently fostering or had previously fostered at least one child from the foster care system. The researcher analyzed the interview data using Braun and Clarke’s reflexive thematic analysis (2019).

Consistent with the Communication Theory of Identity (Hecht, 1993; 2015; Hecht & Phillips, 2022), …

Die Deutsche Nationalversammlung Und Weimar: On The Creation Of Democracy In Weimar Germany, Jason Wendling

Honors Program: Senior Projects (Public)

This paper is a historical analysis of the creation of the Weimar Republic, as well as a political analysis of the Weimar Republic’s constitution. In reviewing both Weimar’s history as well as the constitution, I hope to inspire learners to look back to the Weimar Republic, and not focus primarily on the failures that led to the rise of the Nazi Regime, but rather celebrate the successes that the drafters of the constitution were able to achieve. I review the history of the 1918 November Revolution, the history and party programs of the three important parties of the Weimar Republic, …

Diverse Portfolios: Investing In Tributaries For Restoration Of Large River Fishes In The Anthropocene, Kristen L. Bouska, Brian D. Healy, Michael J. Moore, Corey G. Dunn, Jonathan J. Spurgeon, Craig P. Paukert

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Rehabilitation of large Anthropocene rivers requires engagement of diverse stakeholders across a broad range of sociopolitical boundaries. Competing objectives often constrain options for ecological restoration of large rivers whereas fewer competing objectives may exist in a subset of tributaries. Further, tributaries contribute toward building a “portfolio” of river ecosystem assets through physical and biological processes that may present opportunities to enhance the resilience of large river fishes. Our goal is to review roles of tributaries in enhancing mainstem large river fish populations. We present case histories from two greatly altered and distinct large-river tributary systems that highlight how tributaries contribute …

Differentiating Between Urban Flood Risk As A Unitary Problem And As A Strand In A Braided Problem Set: Implications For Administrative Coordination, Sarah Michaels

Department of Political Science: Faculty Publications

Flood protection is a leading priority for urban water sustainability. Making cities more resilient to flooding has become urgent as the climate changes and as cities increasingly become the loci of human population and resources. Reducing the risk of future flooding in cities often necessitates different jurisdictions working together. They may do so because they confront a shared problem. This was the case in the City of Lincoln, Nebraska, USA, when partnering agencies shared a single focus on reducing flood risk from Beal Slough to the Nebraska State Penitentiary. In contrast, entities may band together to confront braided problems, intertwined …

Carbon Farming: A Preliminary Economic Analysis Of Carbon Credits For No-Till And Cover Crops, Drew Havens, Richard K. Perrin, Lilyan E. Fulginiti

Cornhusker Economics

Summary Based on experimental data about the amount of carbon sequestered and estimated implementation costs, our preliminary results show that the average cost of sequestering carbon via no-till (about $22 per ton of CO₂e) appears to be much lower than the $51 per ton social value of sequestering that ton. In contrast, our preliminary results show that the average costs of sequestration via adoption of cover crops is much higher, about $60 per ton. Depending on how accurate soil carbon models are in predicting sequestration on individual fields to qualify them for enrollment, reimbursement costs for planting cover …

How Do Land Use And Land Cover Changes After Farmland Abandonment Affect Soil Properties And Soil Nutrients In Mediterranean Mountain Agroecosystems?, Estela Nadal-Romero, Makki Khorchani, Leticia Gaspar, José Arnáez, Erik Cammeraat, Ana Navas, Teodoro Lasanta

School of Natural Resources: Faculty Publications

Mediterranean mountains are sensitive agroecosystems that have suffered intense land use and land cover changes (LULCC) during the last century. From the middle of the twentieth century, most of the cultivated lands in Mediterranean mountains were abandoned, allowing the recovery of vegetation (through natural revegetation and afforestation programmes). To examine the effects of farmland abandonment, secondary succession (natural revegetation) and afforestation, an intensive soil sampling was carried out in the Aragu´as catchment (Central Spanish Pyrenees) including sparsely vegetated areas (badlands), grasslands, shrublands and afforested sites. LULCC were mapped, and soil physico-chemical properties were analysed in reference sites (unaltered areas during …

Soybean GmSaul1, A Bona Fide U-Box E3 Ligase, Negatively Regulates Immunity Likely Through Repressing The Activation Of GmMpk3, Jun-Mei Li, Mei-Yan Ye, Chaofeng Wang, Xiao-Han Ma, Ni-Ni Wu, Chen-Li Zhong, Yanjun Zhang, Ninghui Cheng, Paul A. Nakata, Lirong Zeng, Jian-Zhong Liu

Center for Plant Science Innovation: Faculty Publications

E3 ubiquitin ligases play important roles in plant immunity, but their role in soybean has not been investigated previously. Here, we used Bean pod mottle virus (BPMV)-mediated virusinduced gene silencing (VIGS) to investigate the function of GmSAUL1 (Senescence-Associated E3 Ubiquitin Ligase 1) homologs in soybean. When two closely related SAUL1 homologs were silenced simultaneously, the soybean plants displayed autoimmune phenotypes, which were significantly alleviated by high temperature, suggesting that GmSAUL1a/1b might be guarded by an R protein. Interestingly, silencing GmSAUL1a/1b resulted in the decreased activation of GmMPK6, but increased activation of GmMPK3 in response to flg22, …

Nebraska Politics And The Environment: Framing Political Communication In The State Of Nebraska In Comparison To National Level Discourse, Samuel Taylor

Honors Program: Senior Projects (Public)

Environmental public policy has seen little change on the national level in recent decades due to Congressional gridlock. Politicians on both sides of the aisle have entrenched their opposing viewpoints, and their communication on the topic utilizes issue frames to help sway the public to see their side. On the Republican side, these issue frames take the form of the “scientific uncertainty” and “economic consequences” frames. This study, based on issue framing, surveys the communication of Nebraska’s Republican State Senators to determine if they utilize the same issue frames or if they diverge from their national counterparts. By analyzing recent …

With Liberty And Justice For The Wealthy: The Criminalization Of The American Poor, Ashlyn Dickmeyer

Honors Program: Senior Projects (Public)

The last phrase of the Pledge of Allegiance states “with liberty and justice for all”. However, not everyone has access to this liberty and justice. Liberty and justice can be bought in this country for a price, and those who can’t afford to pay it are often left in the hands of those who can. One of the most prominent ways to see this is by analyzing the criminal justice system. Despite clauses in the Fourteenth Amendment and court cases like Gideon v. Wainwright (1963) establishing and upholding that the poor are entitled to equal treatment within the criminal justice …
