Measuring flame, air, and soil temperatures during wildland fires, including wildfires and controlled burns in land management contexts, is crucial for research and applications in fire ecology, safety, and management in a wide array of ecosystems, from grasslands to forests. However, open-source and commercial systems are needed for measuring and logging flame and air temperatures that are user-friendly, economical, modular, and customizable. This paper details the design, development, and validation of the FireLog system. Laboratory validation experiments demonstrated high measurement accuracy, with a minimum coefficient of determination (R2) of 0.98 and the highest observed root mean square error (RMSE) of …

The Overlooked Dynamics Of Sibling Violence: Sociological Perspectives And Intervention Strategies, Rowland Edet

Department of Sociology: Faculty Publications

Sibling violence (SV) represents a pervasive yet underexplored dimension of family violence, encompassing physical, emotional, and psychological abuse. This paper critically examines the intersection of gender dynamics, societal norms, and family structures in shaping SV behaviors. Using social learning theory (SLT) as a foundational framework, the analysis explores how gendered expectations and traditional roles influence the prevalence and forms of aggression, with boys more likely to exhibit overt physical aggression and girls engaging in relational aggression. The paper critiques the deterministic tendencies of SLT, highlighting the agency of individuals in rejecting modeled behaviors, and incorporates intersectionality to address the interplay …

Inactivation Of Zika Virus With Hydroxypropyl-Beta-Cyclodextrin, Cory R. Hewitt, Nicholas J. Wixon, Arthur Gallegos, You Zhou, Victor C. Huber, M. Scott. Killian

Nebraska Center for Biotechnology: Faculty and Staff Publications

Background/Objectives: Zika virus (ZIKV) infection is associated with life-threatening diseases in humans. To date, there are no available FDA-approved therapies or vaccines for the specific treatment or prevention of ZIKV infection. Variation in the ZIKV envelope protein (Env), along with its complex quaternary structure, presents challenges to synthetic approaches for developing an effective vaccine and broadly neutralizing antibodies (bnAbs). We hypothesized that beta-cyclodextrin (BCD) could be used to uniquely inactivate infectious ZIKV without disruption of Env.

Methods: ZIKV was propagated in Vero cells and admixed with BCD. The BCD-treated ZIKV was evaluated for infectivity using immunofluorescence and quantitative …

Microscopic Analysis Of Temperature Effects On Surface Colonization And Biofilm Morphology Of Salmonella Enterica, Zachariah Vice, You Zhou, Sapna Chitlapilly Dass, Rong Wang

Nebraska Center for Biotechnology: Faculty and Staff Publications

Salmonella enterica represents a diverse group of pathogens commonly associated with food contamination including red meat. Even though pre- and post-harvest cleaning and sanitization procedures are widely implemented at meat processing plants to mitigate the hazard, S. enterica cells may escape the process by colonizing, on contact, surfaces in the form of a biofilm that functions as an aggregated microbial community to facilitate mutual protection, antimicrobial resistance, proliferation and dissemination. Biofilm development is a complex process that can be affected by a variety of factors including environmental temperature. We developed methods using scanning electron microscopy and confocal microscopy with a …

Characterization Of Multispecies Microbial Communities At Beef And Pork Processing Plants And Their Impact On Pathogen Stress Tolerance, Rong Wang, Sapna Chitlapilly Dass, Vignesh Palanisamy, You Zhou, Tatum Katz, Joseph M. Bosilevac

Nebraska Center for Biotechnology: Faculty and Staff Publications

Escherichia coli O157:H7 and Salmonella enterica are major foodborne pathogens. Biofilm formation may potentially contribute to product contamination by these pathogens at meat processing facilities. Further, pathogen stress tolerance may vary significantly due to the interactions with the multispecies microbial community at meat plants, which may be affected by processing activity, animal species, and the local selective pressure caused by sanitization practices.

We characterized natural microorganisms collected from floor drains at various areas at three beef plants and two pork plants and analyzed their impact on pathogen sanitizer tolerance.

The pathogen strains were able to integrate efficiently into the multispecies …

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

Helminth Parasites Of Galápagos Mammals: A New Cestode Of The Genus Raillietina From The Endemic Rice Rat Nesoryzomys Swarthi And A Summary Of Parasites From Both Endemic And Invasive Rodents, Scott Lyell Gardner, Emma K. Chesley, Michael C. Friedle, Altangerel Tsogtsaikhan Dursahinhan

Scott L. Gardner Publications

In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from a species of Nesoryzomys and summarize the extent of helminth parasitism in both oryzomyine endemics and introduced species of Rattus. Up to the current time, no helminth parasites have been reported from rodents of the Galápagos, and little work has yet been done describing and synthesizing Galápagos parasite diversity. In historical times, several species of autochthonous rodents have occupied the islands including: Nesoryzomys narboroughi Heller 1904, N. fernandinae Hutterer and Hirsch …

Scalable Machine Learning Framework For Adaptive Irrigation Management Of Maize And Soybean In The U.S. Midwest, Precious N. Amori, Derek M. Heeren, Yeyin Shi, Eric Wilkening, Ivo Z. Goncalves, Guillermo R. Balboa, Daran R. Rudnick, Abia Katimbo, Randall S. Ritzema

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Conventional soil water balance (SWB) irrigation scheduling tools, such as FAO-56-based Spreadsheets and the Spatial Evapotranspiration Modeling Interface (SETMI), rely heavily on manual inputs and periodic field measurements, leading to delayed recommendations and missed opportunities to prevent crop stress. More critically, these tools lack the computational scalability and adaptability to leverage the high-frequency, high-volume datasets now available through modern sensing technologies. As precision irrigation increasingly depends on integrating spatially and temporally nuanced field information, there is a pressing need for decision-support systems that can process Big Data efficiently and respond in real-time. To overcome these limitations, we developed and validated …

Identification Of Benzothiophene-Derived Inhibitors Of Flaviviruses By Targeting Rna-Dependent Rna Polymerase, Leah Liu Wang, Shazeed-Ul Karim, Aidan Hand, Ryan Brunkhorst, Mackenna Petersen, Sarah Altam, Yi Liu, Luwen Zhang, Fengwei Bai, Shi-Hua Xiang

School of Biological Sciences: Faculty Publications

Flaviviruses such as Dengue, West Nile, and Zika viruses are mosquito-borne RNA viruses that can cause serious diseases in humans. To develop effective drugs for treating these viruses’ infections, we create a new approach for developing common or shared drugs that may work for several different viral species of flaviviruses. It is based on the conserved RNA-dependent RNA polymerase (RdRp), which is the key enzyme for viral replication. We built up a common structure of RdRps (POLcon) from their consensus sequence. A conserved Triple-D structural motif was identified at the active site of POLcon that has been used for virtual …

McDonald’s Corporation has experienced rapid growth and expansion across the United States and globally, entering diverse markets despite evolving regulations, dietary trends, and consumer preferences. The company’s marketing strategies and ability to adapt have been strongly influenced by the leadership of its CEOs over time. Most recently, CEO Chris Kempczinski has been tasked with guiding the company through a post–COVID-19 market marked by staffing shortages, economic pressures, declining customer service, and rising consumer expectations. While McDonald’s continues to hold a significant share of the market, it must invest in improved customer service, innovative marketing, and healthier menu options to remain …

Wrongful Birth After Dobbs And The Limits Of Tort Law In Areas Of Dissensus, E. Travis Ramey

Nebraska Law Review

As the abortion debate has raged in this country, a secondary debate over wrongful birth has accompanied it. Wrongful birth is a medical-malpractice-like claim brought by parents who allege that a medical provider negligently failed to provide accurate information about the fetus and that had they received accurate information they would have terminated the pregnancy. Courts rejected the tort theory until Roe v. Wade was decided. Post-Roe, courts were heavily divided over whether to recognize the claim and what damages were recoverable. Now, after Dobbs v. Jackson Women’s Health Organization, the continued viability of wrongful birth is …

Diversity Statements, Academic Freedom, And The First Amendment, Keith E. Whittington

Nebraska Law Review

Diversity statements have become a common component of applications for faculty positions and student admission at universities across the country. They have also become politically controversial, with several states banning the use of such requirements at public universities. The use of diversity statements also raises difficult constitutional questions under the First Amendment at public universities and academic freedom questions at both public and private universities. Although there are versions of such statements that might pass constitutional muster, as commonly designed and implemented, the use of diversity statements likely violates both First Amendment and academic freedom principles. Indeed, diversity statement requirements …

Democracy’S Fundamentals: Efficacy, Equality, And The Supreme Court, Jenny Breen

Nebraska Law Review

When assessing courts in a democratic regime, we must begin by asking substantial questions about what it means for any democratic nation to allocate such important functions to an often unelected branch of government. Courts must fit within a democracy, not democracies within a judicial system. This Essay identifies two fundamental predicates of democratic rule—efficacy and equality—and examines the decisions of the United States Supreme Court in light of both of those key categories, finding that its recent decisions have been consistently undermining both. These observations on the United States Supreme Court are prefaced by overviews of the scholarly literature …

Dreamers And The Fda: Article Iii Standing In Immigration Cases After Fda V. Alliance, Madeline Hutchison

Nebraska Law Review

States historically challenge federal executive policy through litigation. One recent example is Texas’ challenge to the Deferred Action for Childhood Arrivals (“DACA”) policy for the second time in two years. The validity of DACA was challenged in the Fifth Circuit due to immigration concerns by Texas, where the court ultimately held Texas had Article III standing to sue. However other courts, and the Supreme Court in particular, have begun closing the door on plaintiffs that demonstrate only broad injuries related to government regulations and policies. The June 2024 Supreme Court ruling in FDA v. Alliance may open the door for …

The Jurisprudence Of Statutory Interpretation: A Framework For The Logical Restraints Of Legal Positivism And Textualism, K. A. Stenseng

Nebraska Law Review

Since President Donald Trump’s first term in office, the Supreme Court has become increasingly dominated by justices who identify as textualists. In recent years, the Court’s environmental decisions (and the Court itself) have become the center of public scrutiny. As President Trump proceeds through his second term in office, how can legal experts and policymakers better understand the trajectory of the current court? Answering this question is vital as the legal community faces new questions surrounding the Rule of Law.

This Article centers on recent Supreme Court case law, including the Court’s controversial Clean Water Act (“CWA”) decision in Sackett …

Escaping The Pedagogical Cabin In The Woods, Tony Kemerly, Davis Ritenour

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The American educational system, because of its seemingly innocuous yet ubiquitous nature, has become, to borrow a term from Roland Barthes, naturalized. By being naturalized, it has become a system that has somehow slipped beneath the radar of the American populace and operates on an autopilot of sorts that allows it to employ practices that don’t necessarily have the best interests of its constituents at heart. Murray Rothbard (1979) argued that compulsory schooling is not guided by altruism, but rather a desire to coerce the population into a mold that is desired by those possessing power in society. This need …

Fandoms, Postfandoms In The Convergence Of Digital Media: A Case Study Of Youth Cultures From Two Afro-Boricua Musical Genres, Mariely Rivera-Hernández

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The purpose of this work is to analyze the relation between media convergence and a series of habitual activities of youth groups belonging to fandoms. We have established two pedagogical objectives: on the one hand, to analyze the link between media convergence and the participatory culture of fandoms and postfandoms and, on the other, to learn about the cultural consumption of youth cultures in social media and digital platforms. The activity generated in digital communities by several sectors related to the Afro-Boricua musical genres of bomba and plena have led us to the work of cultural ambassadors who circulate and …

Seeing The Strange: Science Fiction, Critical Pedagogy, And Future Teachers, Jeremy Delamarter

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Critical pedagogy, which is the branch of critical theory devoted to uncovering hidden power differentials in educational settings, is too often taught in abstract terms, and future educators fail to understand its relevance to praxis in their future classrooms. As a genre, science fiction is particularly adept at helping students consider the power structures and dynamics occasioned by scientific advances. Even more specifically, science-fiction is a powerful tool for teaching future educators the fundamentals of critical pedagogy. This article provides a philosophical exploration of why science fiction is such a useful tool for teaching critical pedagogy and uses the specific …

Two Birds, Two Stones: Separating Biodiversity Conservation From Patent Law, Jessie Sadlon

Nebraska Law Bulletin (Selected Issues)

The current decline in biodiversity is faster than any other point in human history.[1] Overexploitation is the leading driver of biodiversity loss; species are harvested at unreplenishable rates. Government, non-government, and industry representatives are searching for direction in addressing this rapid species loss. In particular, the World Intellectual Property Organization (“WIPO”) is looking to channel biodiversity conservation through patent systems by instituting an origin disclosure requirement within the patent application process. This paper explores the intersection of biodiversity and innovation, contending the origin disclosure requirement is an unjustified, ineffective mechanism to effectuate biodiversity conservation.

Part II describes the biodiversity crisis …

Parepally, Jun Oki, Fancy Thomas, Helen R. Thorsheim, Abraham J. Al‑Ahmad, Thomas J. Abbruscato, Per Ask, David S. Hage, Peter J. Robinson

David Hage Publications

Background Cerebral blood flow normally places a limit on the magnitude of brain vascular permeability (P) that can be measured in vivo. At normal cerebral blood flow, this limit falls at the lower end of lipophilicity for most FDAapproved CNS drugs. In this study, we report on two methods that can be used to overcome this limitation and measure brain vascular permeability values that are up to ~1000 times higher using the in situ brain perfusion technique.

Methods Rat brain was perfused with physiological saline at increased flow rate and in the presence of various concentrations of plasma protein, serum …

Enhancing Civil Infrastructure Performance Through Lidar-Based Dynamic Monitoring And Phased-Construction Bridges, Khalid Hossam Alkady

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation aims to enhance the performance and structural integrity of civil infrastructure systems through two primary goals. The first goal is to develop and rigorously validate end-to-end frameworks for full-field monitoring of the dynamic response of civil structures via Ground-based Lidar (GBL) scanners. GBL can be employed to sample point clouds at a high sampling rate for dynamic data collection, which addresses the limitations of using contact-based sensors in structural health monitoring (SHM) applications used for early-detection of structural damage.

The second goal of this dissertation concerns the challenges associated with constructing bridges in phases, so they can remain …
