Bromide Removal From Surface Waters By Silver Impregnated Activated Carbon, Chen Chen Jan 2015

Bromide Removal From Surface Waters By Silver Impregnated Activated Carbon, Chen Chen

All Theses

Bromide is a precursor of disinfection by-products (DBPs) during potable water treatment, because it causes the formation of brominated DBPs that are more cyto- and geno-toxic than their chlorinated analogues. Due to the potential health risks of DBPs, the United States Environmental Protection Agency (USEPA) has been imposing increasingly stringent regulations for controlling the DBPs. Therefore, removal of bromide ions from source waters becomes critical for controlling the DBPs formation. In my study, it was hypothesized that silver impregnated activated carbon (SIAC) can be a promising adsorbent for bromide removal from water. The main research objectives of this study were …

Physicocehmical Properties And Pre-Exposure Processes Govern Gold Nanoparticle Accumulation In Freshwater Species, Austin Thomas Wray

All Dissertations

Monitoring the distribution and subsequent effects of nanoparticle (NP) contaminants in aquatic ecosystems will be pivotal to developing regulations that minimize their environmental footprint. Regulators are in a unique position to take a proactive role in shaping how we produce and consume nanomaterials as opposed to the reactive role they have had to adopt with other contaminants. Over the last few decades, researchers have made great strides in describing the fate, behavior, and toxicity of NPs in environmental systems. Recent initiatives have made the transition to scenarios with greater environmental relevance, yet important aspects of fate and behavior remain unexplored. …

The Effects Of Conjugated Linoleic Acid Supplementation On Lipopolysaccharide-Challenged Synoviocytes, Allison Millican

All Theses

Osteoarthritis is one of the leading causes of lameness in the athletic horse. Cases of equine osteoarthritis typically present with synovitis, or inflammation of the synovium. This inflammation in the synovium leads to the production of inflammatory cytokines and eicosanoids. Although these downstream products can be beneficial, overproduction can lead to degradation of cartilage and joint disease. Opportunities to help mitigate or decrease inflammation within the joint are of current interest to the equine industry. One method being investigated is nutritional supplementation. The anti-inflammatory effects demonstrated by CLA supplementation make it a potential prospect for utilization in mitigating joint inflammation. …

Inhibition Of Vibrio Cholerae Biofilm Formation By Water-Soluble Cranberry Extracts, Daniel Pederson Dec 2014

Inhibition Of Vibrio Cholerae Biofilm Formation By Water-Soluble Cranberry Extracts, Daniel Pederson

All Theses

Vibrio cholerae, a Gram-negative bacterium found in natural aquatic environments, is the causative agent of cholera, a severe diarrheal disease most commonly spread through drinking water. An essential component to this pathogen's success and persistence in the environment is its ability to attach to both biotic and abiotic surfaces via biofilm formation. Biofilms not only aid in surface attachment, but also provide a barrier that protects and enhances survival. Water-soluble extracts from the North American cranberry (Vaccinium macrocarpon) were found to dramatically inhibit V. cholerae biofilm formation at a low concentration of 2mg/ml. This inhibition was not due to acidification …

Popular American News Media Explained Through Visual Arts: Using Drawing As A Tool For Humorous And Obligatory Cultural Critique, Joel Murray Dec 2014

Popular American News Media Explained Through Visual Arts: Using Drawing As A Tool For Humorous And Obligatory Cultural Critique, Joel Murray

All Theses

Through my drawings, I focus on jostling the passive American viewer out of her/his complacent acceptance of the images delivered by popular media outlets. Using humor as a multi-functional tool, I combine and reinterpret recognizable media artifacts to comment on the content that makes up American culture. This body of work is a cultural critique, pitting the ridiculous and superficial entertainment we (Americans) so easily ingest against current and crucial moments in time (i.e: political protests, violence, death, etc). Often times, the current media landscape is saturated with fast-cycling images and stories that do not promote careful contemplation. Instead, these …

Invisible Labor And The Preservation Of Dignity, Laken Bridges Dec 2014

Invisible Labor And The Preservation Of Dignity, Laken Bridges

All Theses

My art seeks to question the social value of labor. Throughout history, labor hierarchies influenced by social class and economic stigmas have informed how laborers are viewed in the United States. Physical jobs such as menial and domestic work are a common form of invisible labor that experience debasement and stereotyping. In my art, I use labor-based and ordinary objects as a metaphor for the worker, linking the value or disposability of the object to the societal value of labor. This critique of labor is enhanced by the manipulation of text, by the formal tools of scale and perspective, and …

What Adds Up To Being: The Work Of Tanna Burchinal, Tanna L. Burchinal Dec 2014

What Adds Up To Being: The Work Of Tanna Burchinal, Tanna L. Burchinal

All Theses

My practice takes form around embodied experience. I affect signifiers of the human body within the ordered grid, the scientific text, and the logic of the machine, to highlight the interdependencies of physical bodies and those social constructs that produce and influence identity. We are a part of these constructs that both extend and limit; we are enacting and interacting with them. I do not aim to eradicate these structures of power (without them, our identities are in chaos). Instead, I point out the pitfalls of these constructs that are perceived as unchanging, by making interaction and experience integral to …

Microneedle Arrays For Injection Seeding Of Tissue Engineered Scaffolds, Katelyn Michelle Rye Dec 2014

Microneedle Arrays For Injection Seeding Of Tissue Engineered Scaffolds, Katelyn Michelle Rye

All Theses

Tissue engineered constructs have proven to possess comparable mechanical and physical characteristics to autologous tissues making them suitable replacements fordiseased anatomy when autologous tissue transplants are unavailable. However, difficulty in reseeding the constructs with cells prevents the tissue-engineered scaffoldsfrom becoming an adequate, equivalent replacement for diseased tissues when compared to autologous transplants. Cells adhere to the outer surfaces of scaffolds but are incapable of penetrating the constructs to provide complete cellularization. If cells were able to populate the inner layers of the tissue, then they could likely diffuse into the intimal and external layers of the construct to create a …

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang Dec 2014

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang

All Theses

Shiga toxin-producing Escherichia coli (STEC), a member of Enterobacteriaceae family, has been recognized as emerging pathogens. Dairy compost is commonly applied to farmland as a soil amendment. Despite the agricultural benefit of manure-based soil amendment, the inadequately treated compost can contribute to fresh produce contamination on the farm. Moreover, the epidemiological results showed that the non-O157 STEC cases have surpassed those of E. coli O157. Therefore, it is critical to evaluate the behavior of non-O157 STEC strains in the dairy manure-based compost. The objectives of this study were to: 1) optimize a culturing method for detecting non-O157 STEC from dairy …
