Characterization Of Cucurbitacin-Inspired Estrone Analogues As Novel Inhibitors Of Human Atp- Binding Cassette Proteins (Abcb1 And Abcc1), Jennifer Kyeremateng
Electronic Theses and Dissertations
ATP-binding cassette (ABC) transporters are a large class of integral membrane proteins that contribute to key physiological functions in all organisms by utilizing ATP binding and hydrolysis to transport diverse substrates across membrane barriers. P-glycoprotein (P-gp/ ABCB1) and Multidrug Resistance protein 1 (MRP1/ABCC1) are widely reported ABC transporters associated with multidrug resistance in cancer. Multidrug resistance (MDR) mediated by P-gp and MRP1 is responsible for treatment failures of many metastatic cancers as a result of reduced accumulation, bioavailability and diminished potency of anticancer drugs. Currently, known P-gp and MRP1 inhibitors are limited due to toxicity, lack of selectivity and low …

Go Talk To Your Employee: A Sequential Mediation Analysis Of Leader Communication Frequency And Employee Turnover Intent, Max Weaver
Electronic Theses and Dissertations
Employee turnover has significant negative costs to healthcare organizations. While leadership communication styles and quality have been empirically supported to reduce turnover intentions, our understanding of specific modalities of leader intervention is not well understood. This paper sought to understand how the specific act of communication frequency reduces turnover. Through the lens of Leader-Member Exchange (LMX) and role dynamic theories, mediating effects of LMX quality and job satisfaction were investigated to further understand this proposed relationship in a sample of healthcare workers in the Midwest/US. Results indicate that communication frequency was negatively related to turnover intent. Furthermore, while LMX and …

Development Of A Probabilistic Multi-Class Model Selection Algorithm For High-Dimensional And Complex Data, Madeline Anne Ausdemore
Development Of A Probabilistic Multi-Class Model Selection Algorithm For High-Dimensional And Complex Data, Madeline Anne Ausdemore
Electronic Theses and Dissertations
The development of quantifiable measures of uncertainty in forensic conclusions has resulted in the debut of several ad-hoc methods for approximating the weight of evidence (WoE). In particular, forensic researchers have attempted to use similarity measures, or scores, to approximate the weight of evidence characterized by highdimensional and complex data. Score-based methods have been proposed to approximate theWoE for numerous evidence types (e.g., fingerprints, handwriting, inks, voice analysis). In general, scorebased methods consider the score as a projection onto the real line. For example, the score-based likelihood ratio evaluates and compares the likelihoods of a score calculated between two objects …

Investigating The Development Of Fecal Bacterial Communities In Growing Dairy Calves, Emily Fowler
Electronic Theses and Dissertations
The gut development of young calves is crucial for the producer and the calf's future. Many factors can affect the development of a young calf's gastrointestinal system, and there has been little research into the fecal microbiome development of calves from 0 to 12 weeks of age. To gain further insight into this process, development of the fecal microbiome in 12 dairy calves was investigated. Fecal bacterial composition was determined at four time points (weeks 0, 4, 8 and 12) using the 16S rRNA gene through PCR-amplification of the V1-V3 regions from fecal microbial genomic DNA, followed by Illumina MiSeq …

A Speciation Modeling Study Of Heavy Metal Adsorption To Plastic In Municipal Wastewater Treatment Plant Units, Kaitlyn Hague
Electronic Theses and Dissertations
Microplastics are an emerging concern due to their harmful effect to organisms and their ability to facilitate transport of contaminants including heavy metals. Microplastics can enter the environment through wastewater treatment plants, landfill leachate, and littering. Once in the environment microplastics can be distributed throughout rivers, the ocean, and lakes. In order to understand the adsorption of heavy metals to microplastics a geochemical modeling study was completed using Visual Minteq. Lab tests were completed to better understand what constituents are available in wastewater at four different locations: influent, clarifiers, digesters, and effluent. These constituents were then used to observe how …
Improved Biochar Based Controlled-Release Nitrogen Fertilizers For Sustainable Corn Production, Robiul Islam Rubel
Improved Biochar Based Controlled-Release Nitrogen Fertilizers For Sustainable Corn Production, Robiul Islam Rubel
Electronic Theses and Dissertations
Nitrogen use efficiency (NUE) is an essential factor to increase crop yield. When conventional nitrogen fertilizer (e.g. Urea, Ammonium Sulphate, etc.) is applied in the field, generally over 50% of the N of these fertilizers may lose into the air due to vaporization, or run-off and leaching in rivers and lakes. The N losses lead to not only low NUE but also serious environmental problems. The consequence of N losses results in insufficient N available to meet the demand of crop growth at the growing stages. Lack of sufficient N for crop growth puts a threat of nutrient deficiency and …

Masculinity And Cold War Fairy Tales: Eudora Welty, Vladimir Nabokov, Donald Barthelme, And Ross Macdonald, Susan E. Wood
Masculinity And Cold War Fairy Tales: Eudora Welty, Vladimir Nabokov, Donald Barthelme, And Ross Macdonald, Susan E. Wood
Electronic Theses and Dissertations
This dissertation examines the use of fairy-tale allusions to explore masculinity in four novels published during the Cold War period. This notable focus on men and masculinity held in common across these four novels from four different decades is interesting because it suggests that the shift in focus to women and feminist ideals in fairy-tale revisions of the 1970s and after is even more stark a shift than has yet been recognized by scholars. This dissertation finds that Eudora Welty’s novella The Robber Bridegroom (1942), Vladimir Nabokov’s novel Lolita (1955), Donald Barthelme’s novel Snow White (1967), and Ross Macdonald’s novel …

Enhanced Electrochemical And Light-Driven Co2 Reduction By Incoporating Pendant Functionality In The Second-Coordination Sphere Of Molecular Catalysts, Sayontani Sinha Roy
Electronic Theses and Dissertations
With the increase in global population and rapid industrialization, a gigantic amount of greenhouse gases is being released into the atmosphere each year. The catastrophic effect of these accumulated greenhouse gases is driving global climate change and adversely impacting our ecosystem. Popularizing the traditional renewable energy sources (such as solar and wind energy) can mitigate the problem by cutting down anthropogenic CO2 emissions, which is the major contributor to this global problem. However, the intermittent nature of these energy sources is problematic to reliably power society throughout the year. Therefore, converting CO2 to various value-added chemicals with the aid of …
Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar
Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar
Electronic Theses and Dissertations
Gram-negative unicellular myxobacteria, along with their multicellular lifestyle andbiologically active specialized metabolites, are known for the predatory interactions with Gram-negative/ Gram-positive bacteria and fungi. Although myxobacterial predation range have been exploited extensively, little is known about the prey associated molecules contributing to myxobacterial predator-prey dynamics. By employing transcriptomics and untargeted metabolomics approaches, we demonstrate two structurally distinct classes of signaling molecules from Gram-negative bacterial prey elicit significant omics responses from myxobacteria, Myxococcus xanthus and Cystobacter ferrugineus. An overlapping and general response to acylhomoserine lactones, whereas a distinctive response to a quinolone signaling molecule is observed from both myxobacteria. Similarly, by …

Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon
Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon
Electronic Theses and Dissertations
The selection pressure of predation has encouraged the development of defense traits that can make an individual species more environmentally stable. In addition to biotic pressures, abiotic factors could lead to disruption of predator-prey balance within ecosystems. Consequently, it is significant to better understand how environmental factors can influence predator-prey interactions and how responses may, in turn, affect communities. A current challenge within microbial communities is to understand which intraspecific traits associated with such defense strategies are important for microbial-prey responses to predation, and how the responses vary across environments revealing GxE interactions. In this study, I examined microbial-predator prey …

Electronic Theses and Dissertations
After the passage of the Civil Rights Act of 1964, student and faculty activists at public, flagship universities used existing civil rights organizations and founded new activist groups to bring attention to barriers that hindered their equal power and participation within higher education. African Americans, Mexican Americans, Puerto Ricans, and women created grassroots campaigns and worked within institutional structures to reform universities between 1964 and 1985. Activists worked separately and across gender, racial, and ethnic lines in attempts to gain authority, power, and self-determination within the university system. Students and faculty asserted that flagship universities needed to serve the needs …
Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh
Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh
Electronic Theses and Dissertations
In the rhizosphere, plants curate and maintain distinct rhizobiome, some of which serve as secondary defense mechanisms against pathogenic microorganisms. Additionally, in response to biotic stress, plants generate phytohormones which regulate signaling pathways to activate systemic resistance. These phytohormones contribute to the chemical space within the rhizosphere in addition to other low-molecular-weight metabolites used for cell-to-cell communication within species and across kingdoms. However, little is known about the influences of stress-related phytohormones on beneficial bacteria even though biocontrol strategies abundantly explore plant-beneficial microorganisms to manage pathogens in agricultural systems. Myxobacteria are competent predators of plant pathogens and have demonstrated responses …
