Existence And Multiplicity Of Positive Solutions For One-Dimensional P-Laplacian With Nonlinear And Intergral Boundary Conditions, Xiao Wang

Theses and Dissertations

In this dissertation, we study the existence and multiplicity of positive solutions to classes of one-dimensional singular p-Laplacian problems with nonlinear and intergral boundary conditions when the reaction termis p-superlinear or p-sublinear at infinity. In the p-superlinear case, we prove the existence of a large positive solution when a parameter is small and if, in addition, the reaction term satisfies a concavity-like condition at the origin, the existence of two positive solutions for a certain range of the parameter. In the p-sublinear case, we establish the existence of a large positive solution when a parameter is large. We also investigate …

A Machine Learning Approach To Predicting Seafloor Properties And Their Application In Estimating A Global Methane Hydrate Inventory, Taylor Runyan Lee

Theses and Dissertations

Seafloor properties, including total organic carbon (TOC) and the vertical thickness (isochores) of geological units, are sparsely measured on a global scale and spatial interpolation (prediction) techniques are often used as a proxy for observations. Previous geospatial interpolations of seafloor TOC exhibit gaps where little to no observed data exists. Recent machine learning techniques, based upon a suite of geophysical and geochemical properties (e.g., seafloor biomass, porosity, distance from coast) show promise in making globally complete, comprehensive, and statistically robust geospatial seafloor predictions. Here I apply a non-parametric (i.e., data-driven) machine learning (ML) algorithm, specifically k-nearest neighbors (kNN), to estimate …

Characterizing Flooding Regimes In The Lower Mississippi Alluvial Valley Over Recent Two Decades, Xichun Zhou

Theses and Dissertations

The Lower Mississippi Alluvial Valley (LMAV) was once the largest floodplain in the United States. Flooding regimes in the LMAV have strong impacts on the soil biogeochemical processes, nutrient cycling, forest species distribution, agricultural production, and wildlife habitat. This study characterized the LMAV flooding regimes using the 8-day-composite Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance product from 2001 - 2018. The results showed significant spatial variations in the annual flooding duration in the LMAV, and the flooding area showed remarkable seasonal variations in the northern and central LMAV with the peak flooding area in winter and early spring. Digital Elevation …

Temporal Alterations In Bovine Placental Capacity During Compromised Pregnancies, Zully E. Contreras

Theses and Dissertations

The circadian rhythms are not solely regulated by photoperiod but are also influenced by feed regimen. Therefore, maternal nutrient restriction during gestation could potentially impact the fetal circadian rhythm. Melatonin, a circadian rhythm modulator hormone, has shown to act as an antioxidant reducing reactive oxygen species during stress exposure; and two potential mechanisms have been proposed for melatonin causing vasoconstriction and vasodilation regulating blood flow. In livestock species, nutrient restriction during gestation reduces uterine blood flow, limiting nutrients availability to the fetus for growth and development. Therefore, this project aimed to use beef heifers to evaluate the maternal nutrient restriction …

Penstemon's Centromeric Histone 3 Variation And The Impact Of Soil Steaming On High Tunnel Tomato Production, Xin Ye

Theses and Dissertations

We evaluated the genetic diversity of Penstemon's Centromeric Histone 3 (CENH3), which localizes to chromosome centromeres in eukaryotes. From RNA extractions of 56 species, we successfully amplified two CENH3s (termed CENH3a and CENH3b), which share approximately 69% sequence homology across the length of the gene and about 85% across the histone fold domain (HFD). CENH3a is generally 72 bp longer than CENH3b and contains seven exons while CENH3b is made of five. Unlike studies of CENH3 in other plants, Penstemon's CENH3 N-tail was found to be highly conserved, indicative that the genus has undergone a short evolutionary history. Surprisingly, of …

Money Matters: Factors Associated With Receipt Of Financial Aid Among Youth Who Have Experienced Foster Care, Jacob P. Gross, Jennifer M. Geiger, Greg King, Samuel King

Journal of Student Financial Aid

Despite high aspirations, youth formerly in foster care may face significant barriers (e.g., academic preparedness, adult mentoring) to obtaining a postsecondary credential. Better understanding the relationship between affordability and postsecondary access for youth formerly in foster care (YFFC) merits attention from researchers because finances often present a barrier to success for this population of students. This exploratory study asks the question: What factors influenced whether YFFC received financial aid and do those factors change over time? Using event history analysis and national longitudinal on foster care and youth outcomes, we explore what factors impact whether a YFFC receives financial aid.

An Update On The Assessment And Management Of Pediatric Abdominal Pain., Craig A. Friesen, Jennifer Colombo, Amanda D. Deacy, Jennifer Verrill Schurman

Manuscripts, Articles, Book Chapters and Other Papers

Chronic abdominal pain is very common in children and adolescent and results in high personal and social costs. Most youth with chronic abdominal pain fulfill criteria for a functional abdominal pain disorder (FAPD) as defined by Rome criteria. These are complex conditions with a wide array of biological, psychological, and social factors contributing to the experience of pain. The purpose of the current review is to provide an overview of the pathophysiology of FAPDs and an up-to-date summary of the literature related to FAPDs in children and adolescents, with additional focus on several areas (eg, diet and probiotics) where patients …

Confronting Space Debris Through The Regime Evolution Approach, Gershon Hasin

International Law Studies

This article examines the complex policy problem of space debris and elaborates a proposal for a bottom-up cooperative regime for its mitigation. While debris proliferation generates costs and threatens the safety of personnel and equipment, this policy problem is compounded by the realization that debris constitutes a by-product of desirable space activities which facilitate national progress and domestic increases in values. It is further complicated by increased private participation, conflicting interests of participants, and a global order susceptible to outlier behavior.

Scholars attempting to tackle this policy problem have failed to appreciate the complex legislative process through which international rules …

The functional role of long noncoding RNAs (lncRNAs) in inherited metabolic disorders, including phenylketonuria (PKU), is unknown. We demonstrated that the mouse lncRNA Pair and human HULC associate with phenylalanine hydroxylase (PAH). Pair-knockout mice exhibited excessive blood phenylalanine, musty odor, hypopigmentation, growth retardation, and progressive neurological symptoms including seizures, which faithfully models human PKU. HULC depletion led to reduced PAH enzymatic activities in human induced pluripotent stem cell (hiPSC)-differentiated hepatocytes. Mechanistically, HULC modulated the enzymatic activities of PAH by facilitating PAH-substrate and PAH-cofactor interactions. To develop a therapeutic strategy for restoring liver lncRNAs, we designed GalNAc-tagged lncRNA mimics that …

Agricultural and Environmental Sciences Faculty Research

Management of plant diseases is a subject of concern for researchers as well as growers. Different management practices are being developed and used to combat the rising number of plant pathogens, which threaten nursery crop production. Use of cover crops for sustainable management of soilborne diseases is being explored as an alternative strategy to the chemicals. However, the potential threat of these cover crops acting as a secondary host of these devastating soilborne pathogens has not been described. We studied the response of the major cover crops being used by woody ornamental growers in the Southeastern United States to Phytopythium …

Automatic Identification Of Internal Wave Characteristics Affecting Bathymetric Measurement Based On Multibeam Echosounder Water Column Data Analysis, Karolina Zwolak, Łukasz Marchel, Aileen Bohan, Masanao Sumiyoshi, Jaya Roperez, Artur Grządziel, Rochelle Ann Wigley, Sattiabaruth Seeboruth

Center for Coastal and Ocean Mapping

The accuracy of multibeam echosounder bathymetric measurement depends on the accuracy of the data of the sound speed layers within the water column. This is necessary for the correct modeling of ray bending. It is assumed that the sound speed layers are horizontal and static, according to the sound speed profile traditionally used in the depth calculation. In fact, the boundaries between varying water masses can be curved and oscillate. It is difficult to assess the parameters of these movements based on the sparse sampling of sound velocity profiles (SVP) collected through a survey; thus, alternative or augmented methods are …

Cytokines That Serve As Embryokines In Cattle., Alan D Ealy, Savannah L Speckhart, Lydia K Wooldridge

Faculty Research 2021

The term "embryokine" has been used to denote molecules produced by the endometrium, oviduct, or by embryo itself that will influence embryo development. Several cytokines have been identified as embryokines in cattle and other mammals. This review will describe how these cytokines function as embryokines, with special emphasis being placed on their actions on in vitro produced (IVP) bovine embryos. Embryokines are being explored for their ability to overcome the poor development rates of IVP embryos and to limit post-transfer pregnancy retention efficiencies that exist in IVP embryos. This review will focus on describing two of the best-characterized cytokines, colony-stimulating …

Quantitative Trait Mapping In Diversity Outbred Mice Identifies Novel Genomic Regions Associated With The Hepatic Glutathione Redox System., Rebecca L Gould, Steven W Craig, Susan Mcclatchy, Gary A Churchill, Robert Pazdro

Faculty Research 2021

The tripeptide glutathione (GSH) is instrumental to antioxidant protection and xenobiotic metabolism, and the ratio of its reduced and oxidized forms (GSH/GSSG) indicates the cellular redox environment and maintains key aspects of cellular signaling. Disruptions in GSH levels and GSH/GSSG have long been tied to various chronic diseases, and many studies have examined whether variant alleles in genes responsible for GSH synthesis and metabolism are associated with increased disease risk. However, past studies have been limited to established, canonical GSH genes, though emerging evidence suggests that novel loci and genes influence the GSH redox system in specific tissues. The present …

Masters Projects

Abstract

Introduction

Lung cancer is considered one of the most common cancers in the United States, with the second most common type of lung cancer located in the right lung²⁴. Providing a more aggressive approach to treatments while meeting the needs of the patients would positively impact outcomes. Working in Radiation Oncology since 2013 as a radiation therapist and now a Medical Dosimetrist I seek to compare the efficacy of IMRT, VMAT and hybrid IMRT/VMAT techniques in the treatment of right lung cancer. The purpose of this study was to evaluate if the hybrid plan would be superior …

Disability In Lee Han's Social Integration Films, Dasom Han

Theses and Dissertations

The thesis examines four films by Lee Han—Wandeugi (2011), Thread of Lies (2013), A Melody to Remember (2016) and Innocent Witness (2019)—that highlight disability problems in contemporary South Korea. While exposing the prejudice against and misunderstanding of people with disabilities embedded in society, these motion pictures promote social integration through development of trusted relationships and effective communication within familial structures. The representations of disability indicate that the cinematic images of exclusion can reinforce disabled characters' marginalized identity and promote inclusive efforts among the viewer at the same time. Through textual, cultural, theoretical analysis, it is argued that the films progressively …

Protein-Based Nanofibers And Thin Films For Drug Delivery Applications, Christopher R. Gough

Theses and Dissertations

Corn zein and silk are both widely available, easy to extract proteins making them valuable replacements for synthetics. Zein and silk are also promising biomaterials in several applications. This work explores the use of both proteins as drug delivery vehicles by loading 1-Dimensional micro-nanofibers and 2-Dimensional thin films with model drugs or the topical therapeutic sodium citrate. Using a formic acid solvent, powdered zein protein or silk fibers were dissolved into solution and then casted into 2D films or spun into 1D fibers through air-spraying. During dissolution, therapeutic products are added. SEM images showed that fibers maintain their small diameter …
