Nebraska's Hidden Goldmine: Wind Power On Farms, Adelaide Witte

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Nebraska’s been hesitant to go all in on wind energy. People often worry about things like noise, how turbines look, or even potential impacts on human health. Community concerns are valid and should always be acknowledged. However, addressing them doesn’t require putting all development on hold.

The Myth Of Clean Manufacturing, Andrea Phan

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

We must act now and reform renewable energy credits to reflect real progress. This means tightening Scope 2 rules so that renewable claims are tied to additional, time and location matched, clean power. It means rewarding measurable integration, so that real emissions are avoided, not waived by retroactive certificates. RECs can still play a role, but only in a system that demands we use the tools we already have.

Illustrated Key To Third Instar Larvae Of Forensically Important Calliphoridae From Costa Rica, Roberto Esteban Morales-Montero

Department of Entomology: Distance Master of Science Projects

Forensic entomology in Costa Rica formally began by the end of the 1990s decade, however, the keys utilized to identify the species of Calliphoridae, the most important family of flies that colonize decomposing bodies in Costa Rica, are a compendium of work done by different authors that not include all the species present in the country, and are not adequately illustrated, which could make the analyses difficult for people without the proper knowledge of the carrion flies, or may lead to errors in the identification. The objective of this work is to put together a properly illustrated key for third-instar …

Upland Switchgrass Cultivars Have Similar Bioethanol Production Profile Under Separate Hydrolysis And Fermentation: A Course Based Undergraduate Research Experience (Cure) In Biofuel Production, Kadyn Berg, Derek Follett, Adelyn Jackson, Mark Kalyegira, Jaleigha Kambeitz, Nathaniel Lanthier, Elaina Merfeld, Nathan Nelson, Sara Parliament, Peyton Plagman, Thomas Poegel, Alex Schemek, Sajan Mathew, Brady Steffen, Chloe Van Heuveln, Keerthi Mandyam, Arvid Boe, Ananda K. Nanjundaswamy

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

The modified Course-Based Undergraduate Research Experience (CURE) in bioenergy research evaluated four upland switchgrass cultivars namely Carthage, NE2010, RC Sundance, and Sunburst for bioethanol production using a separate hydrolysis and fermentation (SHF) process. The cultivars were not different in their biomass composition, sugar and ethanol yields. Carthage produced the highest ethanol yield (10 g/L), followed by Sunburst (9 g/L). A strong correlation was observed between glucose concentration at 48 hours (maximum glucose release) and ethanol yield at 72 hours. Ethanol production increased after 48 hours, and by 72 hours, residual glucose levels in the fermentation medium were negligible. The fermentation …

A Previously Unrecognized Species Of Celastrina From The Southeastern Coastal Plain Region Of The United States (Lycaenidae: Polyommatinae) Named In Honor Of The Memory Of Iryna Zarutska, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

New species Celastrina iryna is described from the southeastern coastal plain of the United States. This species is most similar to C. neglecta but differs by possession of the unique dorsal overlay of clear wing scales found in C. ladon males. It is hypothesized that this may be a hybrid species. Some aspects of its life history remain unknown and call for further field research. The species name is a tribute to Iryna Zarutska, of Charlotte, North Carolina.

A History Of Native People In Nebraska, Part I, Gabriel Bruguier

Truth and Reconciliation History Project

The following isn’t a comprehensive history; the aim is to highlight important events and the ideas of those whose actions brought forth the history of the region and eventually the state of Nebraska. Using an analogy from the book The Nebraska State Constitution, we can think of how the state developed as a sort of fence, a way of separating what is “mine” and “yours”, who is “us” and “them,” and who the “insiders” and “outsiders” are.9 In examining the period leading up to the formation of Nebraska Territory, it is instructive to point to how outside forces desired and …

Voices Of Latinidad: A Truth And Reconciliation Movement To Preserve Latino And Latina History, J.S. Onésimo (Ness) Sándoval

Truth and Reconciliation History Project

This chapter began as a quest to tell the story of Latinidad in Nebraska. It is not meant to be a historical account of Latinos or Latinidad, nor a socioeconomic analysis. Instead, it has evolved into an accessible narrative highlighting the accomplishments of Latinos in Nebraska. The accounts and data presented serve as a public testimony and starting point for discussions that acknowledge Latinos’ presence. These accounts were not designed as an academic treatment for scholarly work but aim to inspire future scholars to research the lives and accomplishments of Latinos in Nebraska. Latinos have long been an integral part …

Native Americans, Part Ii, Kevin Abourezk

Truth and Reconciliation History Project

The Civil Rights Movement of the 1950s and 1960s – aimed at abolishing legalized racial segregation and discrimination across the United States – found expression in Nebraska in many ways. From college protests to marches in Lincoln, the movement found a home within the youth and counterculture communities of Lincoln and Omaha. But less known is the way the movement impacted Native American populations, especially those in remote Nebraska communities. “Just as young Hispanics, Asians, and Native Americans across the nation were learning the lessons of the black experience of the 1960s and expressing their identity as they sought to …

Introduction To Roots Of Justice: A History Of Race And Racism In Nebraska, M. Dewayne Mays, Paul Olson

Truth and Reconciliation History Project

Nebraska has made racism a way of life through most of its history. It is still the way of life for many. In 2020, a Nebraska columnist wrote the following about Nebraska: “[T]he issues stemming from racism can seem like foreign concepts, confined to the larger cities (or the American South) and relics of a distant past.”2 The column goes on to show that these issues were not confined to large cities or to the South; they rested on our back door in Nebraska. Yet, one often heard back as far as one could remember that Nebraska is not and …

A History Of African Americans In Nebraska, Preston Love Jr., Adam Fletcher Sasse, Le Clara Gilreath, Portia Love, Heather Fryer

Truth and Reconciliation History Project

Black people have been present in Nebraska from its earliest days as a U.S. territory. The first U.S. Census of Nebraska, conducted in 1860, counted eighty-one Black people who, together, formed .28 percent of the young territory’s 28,841 residents. That number grew to 3,443 Black residents in 1900, representing 3.5 percent of the 102,555 residents of the state of Nebraska. The number and location of Black Nebraskans varied greatly through the twentieth century, comprising 13.7 percent of the state’s population in 1940 and 11.8 percent in 2020. Although African Americans have been relatively small in numbers, the historical record reflects …

Exclusion From The Good Life: The Impact Of Anti-Asian Racism On Asian Nebraskans, Heather Fryer, Sharon Ishii-Jordan

Truth and Reconciliation History Project

To understand how Americans of Asian descent experienced, adjusted, and overcame negative experiences in Nebraska, recognizing the external forces on their lives is paramount. The experiences of Asians in their diaspora across the U.S. and Nebraska during a 150-year span have been shaped by both external (global and domestic) and internal (personality and resilience) factors. The presence of stereotypes specifically targeted toward Asian Americans due to exotic imaginings, pseudoscience, and economic fears, in addition to the images created by national media, gave rise to society’s acceptance of stereotypes. These external factors contributed to a belief that continues to this day …

Zea E-Books Collection

There is much to understand about the history of Nebraska and how the past shapes the present. This book attempts to bring into clearer focus the triumphs and trials of five broad groups whose lives have often been overlooked when the state’s history is told. The authors know some of this history of racism firsthand: Most of them have lived as people of color in Nebraska. They’ve experienced “the good, the bad and the ugly” that makes up our state story. We encourage educators, scholars and family historians to continue to dig, to document and to tell these stories. And …

Exploring Identity Through Six-Panel Memoirs With Collegiate And Secondary Students, Ewa Mcgrail, Lisa York

SANE journal: Sequential Art Narrative in Education

Memoir writing helps to provide mirrors and windows (Bishop, 1990) into the larger human experience by conveying narratives that center on actual life experiences. While memoirs are a well-established genre in literature and literary criticism (Aronowicz, 2024; Kleinbauer, 2007), only recently have graphic novels, including graphic novel memoirs, gained popularity and respect not only among teens, librarians and educators but also among the public (Williams, 2022). In this article, we describe a six-panel memoir assignment completed by collegiate and secondary students and analyze a sampling of memoir creations by both groups of students. Specifically, we are interested in the expressions …

Assessment Of Microbial Quality And Safety, Including Aflatoxin B1, In Buckwheat Flour And Groats, La Fontaine Bahatsi

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

Buckwheat (Fagopyrum esculentum), a gluten-free pseudocereal, has gained popularity in global food markets for its nutritional value and functional properties. However, despite its health-promoting potential, buckwheat is vulnerable to microbial contamination and mycotoxin accumulation during cultivation, processing, and storage. These factors present significant food safety concerns that remain understudied, particularly in North America.

This study investigated the microbiological quality and mycotoxin contamination of buckwheat flour and groats collected from different suppliers via online sourcing. Samples were collected in two consecutive years (2024-2025). Microbiological quality, including aerobic plate counts (APC), Enterobacteriaceae, coliforms, E. coli, yeasts, and molds, was evaluated …

First Confirmed Nebraska Breeding Record Of The Common Raven (Corvus Corax) Since The 19th Century, Eugene A. Huryn, Jacob C. Cooper

Nebraska Bird Review

In Nebraska, the Common Raven was likely widespread prior to 1900, being codistributed with the American Bison (Bison bison). Records in this time are spotty, but consistent. Thomas Say reported a nearly fledged brood—the only confirmed breeding record in this period—at Fort Calhoun in Washington County on May 12, 1820. A Common Raven was collected at Fort Randall, on the Missouri River just north of the modern Nebraska–South Dakota border, in the fall of 1857 during the Lieutenant Warren Expeditions. Another specimen, now lost, was collected by J. B. Hasty in 1899 in Arapahoe, Furnas County. Bruner et …

An Economic Assessment Of Precision Conservation With On-Farm Precision Experiment Data, Karina A. Schoengold, Badri Khanal, Taro Mieno, David S. Bullock

Cornhusker Economics

Using a novel dataset that includes within field variation in productivity, we find that partial field retirement for a prairie strip can not only provide conservation benefits, but can also be economically beneficial. We note that these results are for a single field with one year of data, and that additional years of production and fields are essential to determine how much these results can be generalized. We also note that precision systems can be costly, and a comparison of outcomes with and without this information is essential to determine if investing in such systems is profitable. However, variable rate …

Managing Undesirable Vegetation Transitions On The Landscape: A Study Of Perceptions Of Conservation Professionals In Nebraska And Montana, Anubrata Deka, Simanti Banerjee, Theresa Floyd

Cornhusker Economics

In this bulletin, we have provided a descriptive analysis of the perceptions of conservation professionals in Nebraska and Montana, two states where the rangeland ecosystem is facing a large-scale transition from native grasses to invasive trees and grasses. This analysis provides an initial understanding of the different factors that can influence adoption of policy initiatives by conservation professionals. When considered alongside insights into the management behaviors of ranchers—whose productivity and profitability are adversely affected by these transitions—this information helps form a more comprehensive picture of the ecological and economic impacts of UVTs, as well as strategies for their mitigation. In …

Development Of A Machine Learning Framework For An Irrigation Decision Support System, Eric Wilkening, Derek M. Heeren, Yeyin Shi, Laila A. Puntel, Guillermo R. Balboa, Abia Katimbo, Kuan Zhang, Precious Nneka Amori, Bruno Lena

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Currently used irrigation scheduling techniques often require significant human intervention and are time consuming, particularly for variable rate irrigation. This research aimed to develop a conceptual framework that incorporates disparate data sources leveraging both mechanistic and machine learning (ML) approaches. The overarching objective is to utilize the growing availability of data and technology to manage irrigation more precisely, which will minimize negative impacts of irrigation on our water resources. An initial irrigation machine learning model was proposed and tested in this study as a key component of an edge-cloud computing and federated learning decision-making framework. The specific objectives were (1) …

Mapping Sedimentary And Crustal Thicknesses In The Northern Atlantic Ocean From Public Domain Geophysical Data, Hermione Lofton

College of Arts and Sciences: Undergraduate Theses and Other Student Projects

The Northern Atlantic Ocean is a complex region that contains many inactive and active tectonic features. These features include the Jan Mayen Microcontinent, Jan Mayen Fracture Zone, Aegir Ridge, Kolbeinsey Ridge, the Greenland-Iceland-Faroe Ridge, the Voring Plateau, the Voring Spur, and the Iceland Hotspot. This project is motivated by the region’s complex geology and its highly debated tectonic history and disputed crustal affinity. This study aims to evaluate tectonic elements of the Northern Atlantic Ocean with three major objectives. The first objective is to develop a map of crustal thickness from publicly available seismic refraction data. For the second objective, …

Exploring The Landscape Of Collective Leadership Practice In Rural Nebraska: A Qualitative Sequential Multimethod Study, Haden Myles Botkin

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Rural communities across Nebraska face a myriad of complex challenges that cannot be solved by individual, heroic leaders. As such, collective leadership has begun to emerge in these communities as actors coalesce around local issues. However, little is known about collective leadership practice and development in rural contexts, resulting in a theory-to-practice gap. To that end, this qualitative sequential multimethod study sought to explore how rural community leaders and community development educators perceive, describe, and make meaning of collective leadership practices in rural Nebraska. Three phases comprise this study.

Phase I, the QUAL phase, was guided by the question, How …

Two Essays On Index-Based Risk Management In U.S. Rangeland And Livestock Production, Wajdi Belgacem

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

This dissertation investigates two distinct but complementary dimensions of risk management in United States rangeland agriculture. Essay 1 measures spatial variation in basis risk within the Pasture, Rangeland, and Forage (PRF) rainfall-index program for 176 Nebraska grid cells (1988–2023). By linking official NOAA rainfall indices with 30-m Rangeland Analysis Platform biomass estimates, we find rainfall–forage correlations that peak at 0.45 but display pronounced heterogeneity. The probability that neither insured interval triggers during an actual forage loss averages 12%, rising to nearly 30% in several Sandhills cells, whereas optimally pairing late-spring and summer intervals reduces complete misses below 10%. These results …
