The Environment And Population Differences In Anjan Grass (Cenchrus Ciliaris) In Western India, S C. Pandeya

IGC Proceedings (1977-2023)

Cenchrus ciliaris (anjan or buffel grass) is a gregarious fodder species with high nutritive value. The species is an inhabitant of drier sandy areas throughout Africa, Canary Island, Madagascar and eastwards to India, where it mostly occurs in western parts of the country, constituting the States of Gujarat, Rajasthan, Hayana and the adjoining portions of Punjab, U ttar Pradesh and Madhya Pradesh ( called here in as Western India). In Western India, Cen­chrus ciliaris (Cc) variously dominates the nat­urally occurring grazing lands exhibiting great morphological variations with respect to habit. and spike characters. The ecoclimate of Western India is arid …

Elemental Analysis Of Upper Devonian To Lower Mississippian Organic-Rich Mudstone Cores From Kentucky By Portable X-Ray Fluorescence (Pxrf), Alex M. Washburn

KGS Research Data Set

This dataset contains high-density portable X-ray fluorescence (pXRF) elemental analyses of 1,867 m (6,125 ft) of Upper Devonian to Lower Mississippian organic-rich mudstone cores from Kentucky. Analyses were collected from cores across the Illinois Basin, Cincinnati Arch, and Appalachian Basin to support regional evaluation of elemental variability, chemostratigraphy, and redox-sensitive trace-metal enrichment in Devonian–Mississippian mudstone successions. All measurements were conducted using a Bruker Tracer 5 pXRF analyzer with the factory “Mudrock Air” calibration, using analytical settings optimized for both low-atomic-number elements and transition metals/redox-sensitive trace elements. Reference materials SARM-41 and SGR-1 were analyzed throughout the analytical sequence to monitor instrument …

Soft Korsi: An Embodied Spatial Interior System For Communal Warmth, Faezeh Panahandeh

Graduate Final Projects

ABSTRACT

Soft Korsi: An Embodied Spatial Interior System for Communal Warmth reconceptualizes the historic Iranian Korsi as an innovative textile-based interior system. Traditionally, the Korsi functioned not only as a heating device but also as a spatial, material, cultural, and embodied system, which brought people together around a shared warm focal point. The integration of a heat source, textile coverings, floor seating arrangements, closeness of bodies, and domestic traditions related to warmth made possible a collective experience, rather than an individual or environmental one.

This design project seeks to address the disappearance of the Korsi from contemporary domestic environments as …

Research And Assessment Of Needs For Sign And Signal Maintenance, Megan White, Eric Green

Kentucky Transportation Center Research Report

Kentucky Transportation Cabinet (KYTC) sign and signal crews have expressed multiple concerns related to compensation, expertise, and having the financial and personnel resources needed to help the agency comply with Manual on Uniform Traffic Control Devices (MUTCD) guidelines while continuing to perform routine job duties. Internal reorganizations and personnel changes have reduced staffing and budgets available to underwrite the activities of sign and signal crews even as workloads have remained steady or increased. To document the challenges facing sign and signal crews and associated engineering staff, Kentucky Transportation Center (KTC) researchers administered a statewide survey. Respondents gave their perspectives on …

Building And Facility Asset Inventory Assessment And Maintenance, Catherine Keathley, Bethany Paris, Jon Wilcoxson

Kentucky Transportation Center Research Report

The Kentucky Transportation Cabinet (KYTC) manages approximately 1,500 buildings statewide, including facilities such as office buildings, maintenance and equipment garages, and storage sheds. Because managing buildings and properties requires considerable effort, agency decision makers need reliable monitoring and management tools that generate and organize data which can be used to determine the best course of action for facility maintenance and replacement. In addition to assessing the Cabinet’s building inventory, this report advances recommendations to improve the collection, management, and reporting of facility-related data. Assessment of the inventory managed by KYTC included geolocation of all properties and the buildings therein. Once …

Kytc Crash Modification Factor Recommendation List Online Tool, William Staats, Reginald Souleyrette, Teng Alex Wang, Mohammad Zana Majidi

Kentucky Transportation Center Research Report

Transportation practitioners use crash modification factors/functions (CMFs) to calculate the number of crashes expected once a countermeasure has been implemented. When evaluating design alternatives, CMFs can be used in conjunction with safety performance functions (SPFs) to derive crash predictions. The Federal Highway Administration (FHWA) maintains the CMF Clearinghouse as a repository for CMFs. Contributions are submitted by researchers across the U.S., Canada, and throughout the world. Typically, individual countermeasures are associated with multiple CMFs. Some CMFs only apply to a specific facility or crash types. CMF quality varies, and some only apply to a specific facility and/or crash types, regions, …

Development Of Kytc’S Context Classification Network, Jill Asher, Megan White, Eric Green, Christopher Van Dyke

Kentucky Transportation Center Research Report

Transportation agencies have adopted context-based classification systems that classify roadways based on the surrounding environment and user types. This offers a more comprehensive and multimodal perspective than traditional functional classification. While the Kentucky Transportation Cabinet (KYTC) has begun using project-level context classification, the agency will benefit from introducing network-level context classification. This will improve guidance, enhance project prioritization, and support the development of projects that better address the needs of all users. Responding to this need, Kentucky Transportation Center (KTC) researchers, in conjunction with KYTC staff, created a GIS-based model to build a context classification network that covers all state-maintained …

From Lineage Discovery To Conservation Prioritisation, Zachary G. Macdonald, Joscha Beninde, Julian R. Dupuis, Thomas W. Gillespie, H. Bradley Shaffer, Gregory F. Grether

Entomology Faculty Publications

Accurate inferences of diversification and evolutionary processes depend on knowing how many independently evolving lineages exist within nominally widespread taxa. Uncertainty in lineage number and composition also limits our ability to meaningfully prioritise conservation efforts. Addressing these knowledge gaps requires frameworks that sequentially identify distinct lineages, assess mechanisms that contribute to their divergence, and quantify spatial and environmental determinants of their genomic diversity. With these goals in mind, we apply whole-genome, ecological, and morphological analyses to the American rubyspot damselfly (Hetaerina americana), a widespread and well-studied North American insect that has been long regarded as a single species of least …

Use Of Function Diagrams In Physiology Education, Thad E. Wilson, Brian A. Jackson, B. Peter Sawaya

Physiology Faculty Publications

Function diagrams focus on physiological concepts rather than associated structures and can serve as elaboration tools and mnemonic aids. A function diagram prototype of the gastrointestinal system was recently described (Wilson TE, Barrett KE. Adv Physiol Educ 45: 264-268, 2021). In this article, a functional diagram of the glomerulus, nephron, urinary system, and bladder is proposed. Colloquially named "Nessie the Nephron" to loosely capture the looping structure and elusive understanding of renal blood flow, glomerular filtration, and epithelial transport for the student, not to mention the nearly mythical countercurrent multiplier. "Navigating the Lochs" references Nessie's possible habitat and more importantly …

Since 2016, the Alzheimer's Association and the Fondation Alzheimer have hosted Global Alzheimer's Leadership Series (GoALS) global think tanks, with world-leading experts for innovative discussions to advance Alzheimer's disease (AD) research and care. The second GoALS think tank, held in June 2024 in Paris, focused on the relationship between biological changes and clinical manifestations of AD in the context of the evolving therapeutic landscape. Discussions spanned real-world experiences of providers, patients, and their families, theoretical considerations, and health system challenges. The lived experience perspective was central to these discussions. The importance of shared decision-making, clear and transparent communication, and the …

School Renewal And School Well-Being, Jianping Shen, John Lane, Patricia Reeves, Siche Feng, Xin Ma

Educational, School, and Counseling Psychology Faculty Publications

In this longitudinal case study, we examined school well-being during the change process. We operationalized the change process as the school renewal model and viewed school well-being from the perspective of the PERMA (positive emotion, engagement, relationships, meaning, and accomplishment) model. We found that all elements of the PERMA model were manifested in the school renewal process and that the school renewal process was not dominated solely by conflict and tension, as the literature typically suggests about the change process. The findings of the study suggest the possibility of reframing tension as productive rather than detrimental in the school renewal …

Grassland Development In Japan And Other Asian Countries, I Nikki

IGC Proceedings (1977-2023)

Only since World War II has attention been directed to grassland injapan. Forage crops were introduced on dairy farms for feeding cattle . Acreages have increased and now equal 15 % of the total field area. Forage crops are second to :rice as a major crop . The New Grassland Law, approved in 1950, has led to "grassland improvement" and development of established pastures. J apa:n, situated in the most northern part of the Asian Monsoon Area, is warm as a rule and has much rainfall. Miscanthus sinen­sis Steud. and Zoysiajaponica Steud. are the dominant representative species of natural grassland. …

Collections Of Western Wheatgrass And Blue Grama And Associated Nematode Genera In The Western Dakotas, R E. Barker, J D. Berdahl, J M. Krupinsky, E T. Jacobson

IGC Proceedings (1977-2023)

Western wheatgrass (Agropyron smithii Rydb.) and blue grama (Bouteloua gracilis[Willd. ex H.B.K.J Lag. ex Griffiths) are widely distributed throughout the U.S.A. They arc two of the predominant native grasses in rangelands in the northern Great Plains. Because suitable cultivars are not always available for reseeding disturbed areas, we collected plants of the two species and evaluated phenotypic variability to determine potential for breeding improvement. We also sampled the nematode popula­tion associated with the collections. Sampling sites were systematically chosen by establishing a grid pattern 19 .3 km apart in the western halves of North Dakota and South Dakota. …

Assessing Legacy Collections: Analyzing The Preservation, Recovery, And Interpretive Value Of Archaeobotanical Remains From Site 15le70 (Pine Crest Rockshelter), Lee County, Kentucky, Jennifer Carroll

Graduate Final Projects

This paper uses the archaeobotanical assemblage from Site 15Le70, a multi-excavated and extensively looted rockshelter in eastern Kentucky, while opening new lines of inquiry into gendered labor and practice during the Archaic-Woodland transition. Because legacy collections are often dispersed across institutions and/or research projects, the materials from any single site may be fragmented, as was the case for 15Le70. Such collections can be overlooked, yet this investigation into 15Le70’s archaeobotanical assemblage demonstrates that partial or scattered datasets can yield meaningful results and hold the potential to fill gaps in the archaeological record left by looting.

In this study, a small …

Postoperative Stress Accelerates Atherosclerosis Through Inflammatory Remodeling Of The Hdl Proteome And Impaired Reverse Cholesterol Transport, Dominique M. Boucher, Victoria Lorant, Valerie Rochon, Abigail Carter, Cameron Stotts, My Anh Nguyen, Thomas Laval, Christina Emerton, Nathan Joyce, Nysa Vinayak, Marlena Scaffidi, David Cook, Katey J. Rayner, Rebecca C. Auer, Scott M. Gordon, Mireille I. Ouimet

Physiology Faculty Publications

Over 10 million patients undergoing non-cardiac surgery each year face major cardiovascular complications within 30 days, many due to destabilized atherosclerotic plaques. Reverse cholesterol transport (RCT), driven by HDL and Apoa1, protects against plaque progression, but the effects of surgical inflammation on this pathway remain unclear. Using an abdominal laparotomy model in ApoE^−/− mice on a Western diet, we isolated the impact of surgical inflammation without confounding blood loss. Surgery acutely impaired RCT and cholesterol efflux, with inflammatory remodeling of HDL marked by elevated SAA1/2 and reduced Apoa1. Plaques exhibited higher intracellular lipids, PLIN2 expression, and cleaved caspase-3, indicating …

Liquefaction Susceptibility And Brittleness Of Coal Ash - A State Parameter Approach, Suafa'i Manson, Benoit Wentzinger, Scott Lines

World of Coal Ash Proceedings

Limited data exists on the liquefaction susceptibility of combined fly ash and bottom ash deposits. Their low plasticity and settling density pose a risk of liquefaction under certain triggers. The liquefaction potential is linked to the in-situ state, defining its shearing behaviour as dilative or contractive based on relative density and effective confining stress. This can be assessed using the state parameter (Ψ) concept from critical state soil mechanics theory. This paper presents findings from a follow-up to our 2021 study, which used cone penetration test (CPT) based methods to estimate the in-situ state parameter and perform liquefaction susceptibility screening. …

Sustainability And Waste Diversion At Tva Shawnee "Project Phoenix", Bryan Jacob, Shane Harris

World of Coal Ash Proceedings

An engineered turf closure system can serve as an ideal foundation for a solar energy system to be installed atop coal combustion residual (CCR) impoundments. This approach not only enables productive power generation during the post-closure period, it also preserves opportunities for recovery and beneficial use of CCR material in the future. “Project Phoenix” at TVA’s Shawnee Fossil Plant offers an illustrative example. This paper will cover the sustainability benefits of the companion ClosureTurf® and PowerCap® systems installed at that site as well as waste diversion activities undertaken during construction to recycle as much as practical and minimize waste destined …

Demystifying Large Language Models: How Ai Is Transforming Data, Compliance, And Decision-Making In Coal Ash And Environmental Management, Scott Pfeiffer

World of Coal Ash Proceedings

The environmental and coal combustion residuals (CCR) industries generate vast amounts of information—from groundwater monitoring reports and RCRA documentation to closure plans and analytical data. Managing, interpreting, and communicating this information is a growing challenge for utilities, regulators, and consultants alike. Large Language Models (LLMs), such as OpenAI’s GPT architecture, represent a breakthrough in how organizations can interact with their technical data. These models use deep neural networks trained on billions of words to understand, summarize, and generate language with human-like accuracy. When securely adapted for enterprise use, LLMs can automate routine reporting, extract data from technical documents, generate regulatory …

Calibration Refinement Of Aashto Paveme For Kentucky Asphalt Overlays, Clayton S. Cook, Kean H. Ashurst Jr., Clark Graves

Kentucky Transportation Center Research Report

The Kentucky Transportation Cabinet (KYTC) uses AASHTOWare’s Pavement ME Design Version 3.0 (PaveME) to develop mechanistic-empirical designs for new and reconstructed pavements. Transfer functions used for estimating pavement distress in PaveME rely on national calibration values derived from the Long-Term Pavement Performance (LTPP) database. However, these often fail to reflect Kentucky’s local conditions, materials, and practices. To address this issue, Kentucky Transportation Center (KTC) researchers completed local calibrations for several key transfer functions (rutting, reflective fatigue cracking, and roughness (IRI)) to improve the predictive accuracy of and reduce bias in pavement performance models developed for rehabilitation projects that involve placing …

Earth and Environmental Sciences Faculty Publications

The southern Appalachian orogen preserves a complex distribution of metamorphism and deformation varying in timing, magnitude, and spatial extent. These complexities give rise to disparate interpretations for southern Appalachian tectonic evolution, which complicates the testing and interpretation of tectonic models in this system. New monazite (Mnz) and xenotime (Xtm) laser ablation split stream (LASS) analyses alongside Mnz-Xtm thermometry in the orogenic core in the eastern Blue Ridge (EBR), western Inner Piedmont (WIP), and Cat Square terranes (CST) of North Carolina yield new constraints that define distinct pro- and retrograde metamorphic events. The EBR preserves two prograde thermal events: the Taconic …

Election Fraud In The American Mind, Mitchell Brown, Spencer Goidel, Soren Jordan, Bridgett A. King, Isaac Westfall, Ryan Williamson

Political Science Faculty Publications

Objective: Disputes over election fraud have become a defining feature of contemporary American politics, yet it remains unclear whether partisans are disagreeing about the same underlying phenomenon. This article examines how Americans understand and interpret the phrase “election fraud” and whether partisan divisions reflect differences in concern about fraud or differences in what the term itself is taken to mean. Methods: We use novel survey questions included in our team's module of the 2024 Cooperative Election Study (N = 1000). An open-ended question captures respondents’ own top-of-mind associations with the phrase “election fraud,” while a closed-ended item asks respondents to …

Case Report: Gangrene After One Dose Of Investigational Stannic Pentetate Radiopharmaceutical, Zin W. Myint, Riham H. El Khouli, Bryan P. Lemieux, Charles A. Kunos

Radiology Faculty Publications

Introduction – Bone-seeking radiopharmaceuticals are the treatment of choice with clinical benefits for patients with extensive skeletal metastases, but they can also cause serious radiation-related adverse events (rrAEs). Management of rare and severe radiopharmaceutical rrAEs remains challenging because of incomplete knowledge of their natural history and pathogenetic mechanisms. We report a case of unlikely related gangrene following a protracted hospitalization after one dose of investigational [117mSn]tin-117m-diethylenetriaminepentaacetic acid (Sn-117m-DTPA) for treatment of extensive skeletal metastases from castration-resistant prostate cancer (mCRPC). Case presentation – An 80-year-old man with innumerable painful skeletal metastases from mCRPC developed anorexia and bilateral ankle edema with serous-draining …

Plasmons Enable Ultralow Threshold Solid-State Triplet Fusion Upconversion With A 2d Sensitizer, Seamus S. Lowe, Satya P. Butler, John E. Anthony, Saien Xie, Barry P. Rand

Chemistry Faculty Publications

Solid-state triplet–triplet annihilation (TTA) upconversion has significant potential for application in light harvesting, optoelectronic devices, and bioimaging. However, the high optical powers required to achieve efficient upconversion have inhibited its adoption. In this work, we demonstrate plasmon-enhanced near-infrared (NIR)-to-blue TTA upconversion in a monolayer WSe2/organic heterojunction. Under far-field excitation, the device reaches a threshold of 19 mW/cm2 and an external quantum efficiency (EQE) of 0.17% with an anti-Stokes shift of 1.1 eV. Plasmon excitation lowers the threshold to 0.9 mW/cm2 and improves the EQE to 3.6%. We attribute the plasmon enhancement to surface plasmon polariton (SPP) near-field enhancement and dark-exciton …
