Leaf-Based Varietal Categorization Of Sweetpotato (Ipomoea Batatas L. Lam.), A Potentially Healthful Vegetable, Using Image Processing And K-Means Clustering, Shahidul Islam, Md Towfiqur Rahman, Md Hamidul Rahman, Abdul Momin

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Sweetpotato (Ipomoea batatas Lam) leaves contain higher concentrations of phenolic compounds, flavonoids, and carotenoids that are remarkable in health promotion. However, the nutrient content in sweetpotato leaves varies from variety to variety, and leaf shape and color are the key identifying factors for the varietal classification of sweetpotatoes. So, detecting sweetpotato leaves is essential for the in-situ identification of sweetpotato varieties and for developing intelligent agricultural systems. This study aimed to create a leaf-shape-based varietal classification technique for sweetpotato using image processing techniques coupled with a K-means clustering algorithm. 38 leaf images (RGB) of two sweetpotato cultivars were collected …

In-Season Nitrogen Mmanagement: Leveraging Data Visualization For Precision Agriculture, Chathurika Harshani Narayana

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Effective nitrogen management is vital for sustainable agriculture, impacting both crop yield and environmental health. Traditional methods often use fixed application rates set before planting, which do not adapt to changing crop needs during the season. This can lead to over- or under-application, reducing efficiency and sustainability. While modern tools like sensors, satellites, and UAVs provide valuable real-time data on crop and field conditions, integrating and using this data to guide timely nitrogen decisions remains a major challenge. In-season nitrogen management offers a solution by allowing for dynamic adjustments to nitrogen applications, addressing crop needs as they arise. This approach …

Supporting English Language Learners In Agricultural Education: A Document Analysis, Ellie Chitwood

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

In Nebraska’s rural agricultural education classrooms, increasing numbers of students learn English as a second language, yet support tailored for these learners remains limited. This study explores how English Language Learner (ELL) resources are organized, accessed, and utilized within Nebraska’s agricultural education system. Drawing on Bandura’s Social Learning Theory and leadership education frameworks, a qualitative document analysis examined state policies, Educational Service Unit (ESU) supports, and professional development materials. Findings reveal a coherent statewide policy overshadowed by uneven regional implementation and limited agricultural contextualization. Despite resource disparities and technological constraints, agricultural educators demonstrate leadership by innovating bilingual supports and fostering …

Integrated pest management uses a variety of tools coupled with historical, current, and projected information for economical pest protection of crops and other resources while accounting for risk to humans and the environment. Following the 1972 US Federal IPM Policy, funding for integrated pest management programming has continued for 50+ years. However, multifaceted changes during this time have significantly affected state-level integrated pest management infrastructure, prompting a comprehensive survey to assess conditions, limitations, and growth potential of US integrated pest management programs. A survey was sent to 50 US states and 3 territories with integrated pest management programs in November …

Reconciling Jekyll And Hyde: The Future Of Masculinity Research Within The Domestic Violent Extremism Context, Sam T. Hunter, Brett H. Neely, Carter Welch, Amanda N. Moeller

Department of Management: Faculty Publications

Violence among young men in the United States has escalated in recent years, leading to two contrasting perspectives of young men—either as (a) agentic aggressors or (b) by-products of societal shifts that have caused disadvantage. The first perspective characterizes men as entitled and reactionary, prone to aggression when their societal expectations are unmet. This view aligns with the frustration-aggression hypothesis in which unmet desires lead to hostile behaviors, particularly among individuals who perceive a loss of status and significance. Conversely, the second perspective views men as victims of rapid societal changes, such as job displacement, educational disparities, and shifting gender …

Cover Crops Can Reduce Greenhouse Gas Emissions From No-Till Maize In Southern Brazil: Insights From A Long-Term Field Experiment, Guilherme Rosa Da Silva, Adam J. Liska, Cimélio Bayer

Adam Liska Papers

Brazil is one of the countries that has the most agricultural area under no-till (NT) management. This research study aims to evaluate life-cycle greenhouse gas (GHG) emissions from maize (M) grain production in agroecosystems that used different cover crops under NT management in southern Brazil. The data for this study were from a long-term 41-year field experiment in southern Brazil. The long-term experiment evaluated the effects of fallow (F) and cover crops (oat (O), vetch (V), cowpea (B), pigeon pea (P), and lablab (L)) on nitrous oxide and methane emissions and soil carbon (C) sequestration in maize agroecosystems. Five cropping …

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 …

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.

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 …

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 …

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 …

Distribution And Ecology Of The Cedar Keys Mole Skink (Plestiodon Egregius Insularis), Kevin M. Enge, Louis A. Somma, Paul E. Moler, Travis M. Thomas, Matthew T. Fedler, John M. Matter, Dennis C. Haney

Papers in Herpetology

We conducted surveys for the Cedar Keys Mole Skink, Plestiodon egregius insularis (Mount), during 1989– 1999 and 2015–2024, examined museum vouchers, and compiled personal observations from others to determine the status and distribution of this subspecies, which has the smallest geographic distribution of the five subspecies and is being considered for federal listing. We observed Cedar Keys Mole Skinks on Airstrip Island, Atsena Otie, Cedar Point, Deer Island, North Key, Scale Key, Seahorse Key, Snake Key, and possibly Dog Island. We have anecdotal reports of Mole Skinks on Way Key, which contains the most potential habitat and is the main …

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 …

The Black-Market Commodification Of Human Organs And Bones: A Marxist Perspective, Erik Schulz

Nebraska Anthropologist

The trade and treatment of human remains, while seemingly straightforward, have increasingly become subjects of ethical and moral debate. Over time and in light of recent events, questions have emerged regarding the appropriateness of how human remains are handled and exchanged. This paper examines these issues through the lens of Marxist framework and the perspective of forensic anthropology. The objective is to provide contextual understanding and encourage a reevaluation of current practices, particularly within academic settings, to ensure that human morals, dignity and ethical standards are upheld.

Review Of The Land Of Open Graves: Living And Dying On The Migrant Trail, Lillie Turpin
