Evaluating The Enzymatic Activity Of Transformed X. Cucurbitae, Emily Beger, Iris Lee, Sarah Hind

PRECS student projects

Introduction

  • The United States’ pumpkin industry exceeds one billion dollars [1], with Illinois contributing to over 90% of processing pumpkin production.
  • Pumpkin growers face a rising concern due to the increasing occurrence of Xanthomonas cucurbitae , the pathogen that causes bacterial spot disease in cucurbits, including pumpkins.
  • X. cucurbitae infection leads to the appearance of small, sunken, beige spots on cucurbit fruits and leaves.
  • Over time, the bacterium can compromise fruit integrity by breaking down the epidermis and cuticle. • Bacterial spot disease also creates opportunities for other bacteria and fungi to infiltrate the affected fruits, leading to fruit rot …

Environment and Society Faculty Publications

This paper analyzes the end uses—food, feed, fiber, fuel, and exports—of biomass production in the U.S. in 1997, 2002, 2007, and 2012. They are also analyzed at the state level in 2012. Biomass production is measured as human appropriation of net primary production (HANPP), an ecological footprint measured as carbon fixed through photosynthesis, derived from data on crop, timber and grazing yields. HANPP was allocated to end uses using publicly available sources from the U.S. Department of Agriculture and internet-based sources publishing data on agricultural trade. HANPP was 717–834 megatons (MT) of carbon per year, which comprised 515–615 MT of …

Unlocking Potential: The School-To-Prison Pipeline For Students With Disabilities, Navena F. Chaitoo

Dissertations, Theses, and Capstone Projects

This research uses quasi-experimental, matched sampling to examine the school-to-prison pipeline for students with disabilities using data from the National Longitudinal Study of Adolescent to Adult Health. This study presents novel insights into an at-risk group that has faced disproportionate rates of school discipline and incarceration. The study finds school suspension to be associated with future involvement in the criminal legal system and lower educational attainment. Disability was not found to mediate the relationship between suspension and future involvement in the criminal legal system or the relationship between suspension and academic outcomes. However, disability was found to be a statistically …

Historical And Future Projections Of Supercell Precipitation Contributions To The Hydroclimate Of The United States, Aaron Zeeb Jan 2023

Historical And Future Projections Of Supercell Precipitation Contributions To The Hydroclimate Of The United States, Aaron Zeeb

Graduate Research Theses & Dissertations

Rotating storms, or supercells, are frequent producers of significant tornadoes, hail, and nontornadic winds and an underappreciated genitor of extreme precipitation rates and flash floods. Little research has examined the precipitation contributions from supercells to the overall hydroclimate of the CONUS and, provided that these storms and their precipitation rates may shift in the future due to climate change, it is important to understand their characteristics from both historical and future perspectives. This research seeks to understand supercell precipitation characteristics across the CONUS using high-resolution, convection-permitting, dynamical-downscaled simulations for three, 15-year epochs. Epochs include a historical end-of-20th-century period (1990–2005) and …

Capstone Showcase

Mass shootings in America have been a recurring issue for years. In this project, we examine mass shootings that have occurred in the United States from 1966 to 2022. Through exploratory data analyses, we explore patterns and trends in shooting events, as well as various patterns in shooters, such as their mental health status, relationship status, social media usage, evidence of trauma in adulthood, and ongoing stressors during the time of the shooting. We also utilize natural language processing (NLP) tools to analyze text information in the dataset, such as the shooters' school performance, community involvement, and past signs of …


Convolutional-Neural-Network-Based Des-Level Aerodynamic Flow Field Generation From Urans Data, John P. Romano, Oktay Baysal, Alec C. Brodeur Jan 2023

Convolutional-Neural-Network-Based Des-Level Aerodynamic Flow Field Generation From Urans Data, John P. Romano, Oktay Baysal, Alec C. Brodeur

Mechanical & Aerospace Engineering Faculty Publications

The present paper culminates several investigations into the use of convolutional neural networks (CNNs) as a post-processing step to improve the accuracy of unsteady Reynolds-averaged Navier–Stokes (URANS) simulations for subsonic flows over airfoils at low angles of attack. Time-averaged detached eddy simulation (DES)-generated flow fields serve as the target data for creating and training CNN models. CNN post-processing generates flow-field data comparable to DES resolution, but after using only URANS-level resources and properly training CNN models. This document outlines the underlying theory and progress toward the goal of improving URANS simulations by looking at flow predictions for a class of …

United States Department of Agriculture Wildlife Services: Staff Publications

Chagas disease, a significant public health concern in the Americas, is caused by a protozoan parasite, Trypanosoma cruzi. The life cycle of T. cruzi involves kissing bugs (Triatoma spp.) functioning as vectors and mammalian species serving as hosts. Raccoons (Procyon lotor) and opossums (Didelphis virginiana) have been identified as important reservoir species in the life cycle of T. cruzi, but prevalence in both species in the southeastern United States is currently understudied. We quantified T. cruzi prevalence in these two key reservoir species across our study area in South Carolina, USA, and …
