Age And Water-Quality Characteristics Of Groundwater Discharge To The South Loup River, Nebraska, 2019, Christopher M. Hobza, John E. Solder

United States Geological Survey: Water Reports and Publications

Streams in the Loup River Basin are sensitive to groundwater withdrawals because of the close hydrologic connection between groundwater and surface water. The U.S. Geological Survey, in cooperation with the Upper Loup and Lower Loup Natural Resources Districts, and the Nebraska Environmental Trust, studied the age and water-quality characteristics of groundwater near the South Loup River to assess the possible effects of a multiyear drought on streamflow.

Groundwater sampled in wells screened in Quaternary-age deposits displayed a wide range of mean ages (27 to 2,100 years), fraction modern, and susceptibility index values. Groundwater with higher concentrations of chloride and higher …

Karst Spring Discharge Modeling Based On Deep Learning Using Spatially Distributed Input Data, Andreas Wunsch, Tanja Liesch, Guillaume Cinkus, Nataša Ravbar, Zhao Chen, Naomi Mazzilli, Hervé Jourde, Nico Goldscheider

KIP Articles

Despite many existing approaches, modeling karst water resources remains challenging as conventional approaches usually heavily rely on distinct system knowledge. Artificial neural networks (ANNs), however, require only little prior knowledge to automatically establish an input–output relationship. For ANN modeling in karst, the temporal and spatial data availability is often an important constraint, as usually no or few climate stations are located within or near karst spring catchments. Hence, spatial coverage is often not satisfactory and can result in substantial uncertainties about the true conditions in the catchment, leading to lower model performance. To overcome these problems, we apply convolutional neural …

Economic Implications Of The Mexican Fruit Fly Infestation In Texas, Samuel D. Zapata

Journal of Extension

The Texas citrus industry is threatened by the presence of Mexican fruit fly. The objective of this study was to estimate the economic losses caused by this invasive pest. Economic impact is estimated in terms of loss in revenue and increase in operating costs. Under current quarantined areas and pest management strategies, the Texas citrus industry could experience an annual economic loss of $5.79 million. The analysis was extended to evaluate the economic impact associated with different quarantined area scenarios. This article can be used to increase awareness and adapted to estimate the economic impact of emerging invasive pest outbreaks.

Fad Diets: Professional Development Needs Among Nutrition Agents In Select Southern States, Abigail P. Mcalister, Vicky L. Green, Simone Camel, Mary C. Fontenot, Janet F. Pope

Journal of Extension

Because FCS agents teach communities about dietary guidelines, it is important that they are aware of the latest nutrition research. This study assessed FCS agents’ knowledge of popular fad diets (low-carbohydrate, intermittent fasting, detoxes and cleanses) and their potential adverse effects, and its relationship among location, certifications, years of experience, professional association memberships, and education. Agents in Louisiana, Texas, Arkansas, and Mississippi were emailed a survey. RDN, DTR, and CHES certifications had significant associations (p = 0.03) with knowledge of adverse effects of fad diets. Agents who hold these credentials may have more knowledge about adverse effects of fad diets.

A Needs Assessment Survey Of Southern California Pest Management Professionals, Siavash Taravati

Journal of Extension

Pest Management Professionals were surveyed in training workshops/meetings in Southern California between 2015 and 2017 to understand their needs, challenges, and view of integrated pest management. The most encountered pests by pest control technicians were ants, cockroaches, rodents, spiders, termites, and bed bugs. The most challenging pest groups to control were bed bugs, cockroaches, ants, and rodents. The main challenges that professionals faced in doing their work were regulations, followed by managing pests, and customer-related problems. Most participants had a favorable view of IPM. However, they faced several challenges in implementing IPM, among which customer-related issues were the most common.

Toxicological Assessment Of Zinc Oxide And Titanium Dioxide On Staghorn Coral, Acropora Cervicornis, Katherine E. Meurer

All HCAS Student Capstones, Theses, and Dissertations

Coral reefs are one of the most diverse and biologically significant ecosystems on the planet. However, anthropogenic impacts have led to a global decline in overall reef health in recent years. To address concerns that organic ultraviolet filters in sunscreen may contribute to reduced coral health, the mineral UV filters, zinc oxide (ZnO) and titanium dioxide (TiO₂), have become more common in sunscreen formulas as they are often considered “reef safe” despite limited information on the toxicological effects of these compounds in corals. This study evaluated the effects of exposure to unmodified forms of zinc oxide or titanium …

An Analysis Of Suspended Microplastics In Sewage Outfalls, Inlets, And Coastal Waters Of Broward County, Florida, Katrina A. Smith

All HCAS Student Capstones, Theses, and Dissertations

The widespread use of plastics has led to a surplus of plastic waste in landfills and the ocean. The degradation of these plastics produces microplastics, which are detrimental to the environment. Microplastics can be introduced into the ocean in several ways, including runoff and sewage outfalls; both pathways can concentrate microplastics and promote adsorption of environmental contaminants to the plastic's surface. South Florida has six sewage outfalls, and nine inlets, whose proximity to the Florida Reef Tract increases the potential exposure of microplastics to sensitive environments, such as the coral reef. A quantitative assessment of microplastics introduced into the ocean …

Supply Chain Disruption: A Conceptual Framework On Decision Making Using Neuroscience, Sadiya Siddique

Theses

The simplest definition of supply chain is the delivering of goods and/or services to the consumers required by the organization. In the late 1950s it was identified that the supply chain system was becoming more uncertain due to the changes in demands and inventory. Due to globalization and other business factors, supply chain has become more complex now due to which the likelihood and impact of disruption has increased. These disruptions can vary between known-unknowns and controllable to unknown-unknowns and uncontrollable ones. In recent years, the major disruptions happening in the supply chain and its effects on bottom line of …

Sederoff, Hairong Wei, Ping Zhu, Fay Wei Li, Ray Ming

Michigan Tech Publications, Part 1

To date, little is known about the evolution of fern genomes, with only two small genomes published from the heterosporous Salviniales. Here we assembled the genome of Alsophila spinulosa, known as the flying spider-monkey tree fern, onto 69 pseudochromosomes. The remarkable preservation of synteny, despite resulting from an ancient whole-genome duplication over 100 million years ago, is unprecedented in plants and probably speaks to the uniqueness of tree ferns. Our detailed investigations into stem anatomy and lignin biosynthesis shed new light on the evolution of stem formation in tree ferns. We identified a phenolic compound, alsophilin, that is abundant in …

Performance Projection Of A High-Temperature Co2 Transport Membrane Reactor For Combined Co2 Capture And Methane-To-Ethylene Conversion, Xin Li, Kevin Huang, Noah Van Dam, Xinfang Jin

Faculty Publications

Direct conversion of methane into ethylene through the oxidative coupling of methane (OCM) is a technically important reaction. However, conventional co-fed fixed-bed OCM reactors still face serious challenges in conversion and selectivity. In this paper, we apply a finite element model to simulate OCM reaction in a plug-flow CO₂ /O₂ transport membrane (CTM) reactor with a directly captured CO₂ and O₂ mixture as a soft oxidizer. The CTM is made of three phases: molten carbonate, 20% Sm-doped CeO₂ , and LiNiO₂ . The membrane parameters are first validated by CO₂ /O₂ flux …

Adoration Above Objectification: The Promotion Of Other In Black, Mexican And Arabic Love Poetry, Joycelynn L. Baker

Honors Projects

This paper analyzes the philosophical fundamentals of sexual objectification and presents opposing literature, written in the 20th century, by Black, Mexican and Arabic male poets in contrast. In vigorous patriarchal environments that provide more opportunities to practice sexual objectification, the poets reframe male metaphysical perception and behavior in romantic or sexual contexts by promoting the autonomy and agency of women above themselves, and displaying their enjoyment of that situation. This paper will discuss how Western metaphysical philosophy impacts self-perception and belief in contemporary romantic contexts.

Heterogeneity Of Gene Expression In Peanut-Allergic Cells May Be Related To Differing Cell Subpopulations, Sophia R. Tekorius

Honors Projects

Peanut allergies can have severe and life-threatening complications. By understanding the biology of individuals struggling with this disease, better treatments can be developed. This project explores the possibility of two phenotypically distinct cell types within CD154+ cell types in patients with peanut allergy. Previous studies show that there is a Th2 cell subpopulation associated with allergies, and within effector CD4+ memory populations two distinct phenotypes have been found. This project expands upon this research at the genetic level and through bioinformatic analyses, including the production of heatmaps, the project has found evidence for differing gene expression in two cell subpopulations. …

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

Scientific success in the field of chemistry depends upon the mastery of a wide range of soft skills, most notably scientific writing and speaking. However, training for scientific communication is typically limited at the undergraduate level, where students struggle to express themselves in a clear and logical manner. The underlying issue is deeper than basic technical skills; rather, it is a problem of students’ unawareness of a fundamental and strategic framework for writing and speaking with a purpose. The methodology has been implemented for individual mentorship and in our regional summer research program to deliver a blueprint of thought and …

Modern Monetary Theory: Merits, Critiques, And Contemporary Implications, Rebecca Singleton, Thomas Herndon

Honors Thesis

The study of macroeconomics is a diverse field, with conflicting opinions and numerous camps of thought. The election of 2016 brought this to the public attention, as the appointment of Stephanie Kelton as Senator Bernie Sanders’s campaign economic advisor brought Dr. Kelton’s heterodox school of macroeconomic policy to the attention of mass media. In particular, Modern Monetary Theory became a public discussion, particularly in the wake of stimulus spending during the COVID-19 pandemic. Modern Monetary Theory (MMT), a heterodox macroeconomic theory most discussed in far-left and post-Keynesian academic circles, has faced backlash from a centrist mass media. I investigate the …

Engaging The Adult College Student: A Case Study On Improving Nontraditional Students’ Persistence, Conzolo L. Migliozzi

Instructional Design Capstones Collection

Nontraditional students, defined as those age 25 and older, had a first-year persistence rate of just 46.8% in 2019 (National Student Clearinghouse, 2021). The Education Fund, a large non-profit that provides training and tuition assistance to healthcare workers, is acutely aware of this problem as its membership is made up almost entirely of nontraditional learners. The Education Fund has many college readiness programs, and in an effort to improve upon their outcomes, requested this study on student persistence. Research on nontraditional student persistence was conducted and key Education Fund staff were interviewed as part of this project. While the literature …
