(2019-04-17)
The Fusarium oxysporum species complex (FOSC) is an important group of filamentous fungi that are able to infect both animals and plants. Based on its economic importance, an effort has been made to better understand the ...
The Effects of Community Partnerships on K-12 Computer Science Education
(2019-04-17)
Technology is a critical component of the American economy. Analysts have claimed it is imperative that the United States maintain its status as a worldwide leader in technology or its economy, standard of living, and ...
Testing Erosion Potential of Heterogeneous Lithologies to Understand Atypical Valley Morphology in the Buffalo National River Watershed, Arkansas
(2019-04-17)
The effect of heterogeneous lithologies on valley morphology in tectonically stable landscapes is
an unresolved question in fluvial geomorphology. The upper reaches of the Buffalo National River
incise the Mississippian ...
Building Better Graphs for Climate Change Communication: Evidence from Eye-Tracking
(2019-04-17)
Reducing harm from global climate change will require public participation and therefore public education. Visual data representations such as graphs are often used for communication with public audiences but they are ...
Design Guidelines for Creating Visual Hand Management Board Games
(2019-04-17)
This thesis develops a design guideline for a visual hand management board game. There are more and more board game players all over the world. However, in an independent survey with one thousand respondents, 25% people ...
Hamilton Cycles In Multipartite Graphs With Two Associative Classes
(2019-04-17)
In this dissertation, the following two problems are considered: the embedding problem of when a k-edge-coloring of a multipartite graph G can be embedded into a Hamilton decomposition of multipartite graph H containing ...
Use of metabolic assays to assess thermal and hypoxia stress of freshwater mussel species from central Texas
(2019-04-17)
Warming temperatures are a major concern for freshwater mussels as they are limited in range, mobility, and potential to seek refuge from heat stress. Unionid mussels are ectothermic organisms, and the temperature of their ...
Exploring an Explanatory Child Speech Intelligibility Model Using Phonetically Contrasted Word Productions
(2019-04-17)
Purpose: In clinical practice, there is no standard measure of intelligibility that explains the kinds of difficulties that listeners who are inexperienced with child speech may encounter. This study aimed to investigate ...
Knowledge and Treatment of the Down Syndrome Population in Speech-Language Pathology: A National Survey
(2019-04-17)
The purpose of this study was to determine the extent to which speech-language pathologists possess both knowledge of Down syndrome and confidence in their clinical abilities to treat the population and their families. ...

(2019-04-17)
CHAPTER 1 Synthesis of functionalized p-terphenyl-containing macrocycles as key intermediates in the synthesis of functionalized [n]CPPs
Strategically designed, substituted para-terphenyl-containing macrocycles are ...
Impact of Tree Inoculation by Leptographium terebrantis on Soil Microbial Communities in Commercial Loblolly Pine Stand
(2019-04-17)
A variety of abiotic and biotic stressors, including root-feeding bark beetles and pathogenic ophiostomatoid fungi, are associated with root disease of Pinus spp. Our research goal was to analyze if a tree inoculation by ...
Evaluation of an Algal Turf Scrubber™ (ATS) Approach for the Remediation of Perfluoroalkyl Substances (PFAS)
(2019-04-17)
Per- and polyfluoroalkyl substances are a large group of synthetic organic chemicals ubiquitous and persistent in the environment due to their fluorinated alkyl chains. Existing methods for remediation of mixtures of PFAS ...
Sod-Based Rotation Systems: Research for Whom?
(2019-04-17)
Over the last two decades, a Southeastern multi-institutional, multidisciplinary research team developed a low-input sod-based rotational system with integrated cattle (SBRC) to improve sustainability for small- to medium-size ...
A Study of Electrochemical Impedance Spectroscopy of β-alumina Na2O·11Al2O3 and NASICON Type Li1.3Al0.3Ti1.7(PO4)3
