Mapping Quantitative Trait Loci Associated With Resistance To Bacterial Spot (Xanthomonas Arboricola Pv. Pruni) In Peach, Nannan Yang

All Dissertations

Bacterial spot, caused by Xanthomonas arboricola pv. pruni (Xap), is a serious disease that can affect peach fruit quality and production worldwide. This disease causes severe defoliation and blemishing of fruit, particularly in areas with high rainfall, strong winds, high humidity and sandy soil. The molecular basis of its tolerance and susceptibility in peach is yet to be understood. To study the genetics of the peach response to Xap, an F2 segregating population between two peach cultivars, `Clayton', a resistant phenotype, and `O'Henry', which is very susceptible to Xap, was created. Phenotypic data for leaf and fruit response to Xap …

Villager Participation In The Relocation Of El Gourna, Egypt, Paul Duggan

All Dissertations

ABSTRACT
In 2005, approximately 850 families from the historic village of El Gourna, Egypt were relocated to a new village. The relocation was part of a government initiative to protect ancient records and artifacts from Egypt's Middle Kingdom contained in the Tombs of the Nobles that lay beneath the houses of the village. A special feature of the relocation was an effort made the local authorities to involve of local village leaders and residents in the process.
In the 1990s, about 8 to 10 million people per year were involuntary relocated due to large development projects, or about 100 million …

Serious Tourism And Consumer Preference For Sustainable Tourism Certifications, Richard Lacher

All Dissertations

Demand for sustainability oriented vacation options is on the rise as consumers become more aware of the negative effects that their travel may have on various destinations. Certifying tourism businesses as sustainable (much in the way organic food or fair trade coffee is certified) has been proposed as a means to ensure that ecotourism operations actually follow the principles of sustainable development. This study uses a serious tourism framework and a stated preference choice modeling approach to evaluate consumers' preferences for different types of sustainable tourism certifications. Additionally, willingness to pay (WTP) for different types for certifications is important so …

Genetic Engineering Of Turfgrass For Enhanced Performance Under Environmental Stress, Man Zhou

All Dissertations

Turfgrass species are agriculturally and economically important perennial crops that are susceptible to biotic stress (e.g. fungal pathogens) and abiotic stress (e.g. salinity and drought). Every year, environmental stress significantly influences turfgrass quality and production causing economic loss globally. My research explores the feasibility of using two novel transgenes - Penaeidin4-1 (Pen4-1) from the shrimp, Litopenaeus setiferus, and microRNA319a (miR319a) from the rice, Oryza sativa, to genetically engineer turfgrass for enhanced tolerance to environmental stress.
The antimicrobial peptide - Pen4-1 has been reported to possess in vitro antifungal and antibacterial activities against various economically important pathogens. In this study, two …

Ambiguous Science And The Visual Representation Of The Real, Curtis Newbold

All Dissertations

The emergence of visual media as prominent and even expected forms of communication in nearly all disciplines, including those scientific, has raised new questions about how the art and science of communication epistemologically affect the interpretation of scientific phenomena. In this dissertation I explore how the influence of aesthetics in visual representations of science inevitably creates ambiguous meanings. As a means to improve visual literacy in the sciences, I call awareness to the ubiquity of visual ambiguity and its importance and relevance in scientific discourse. To do this, I conduct a literature review that spans interdisciplinary research in communication, science, …

The Nutritional And Microbiological Characteristics Of An Equol-Enriched Table Egg Produced In A Free-Range Or Conventional Production System, Michelle Parisi

All Dissertations

The specialty foods market has grown by 30% since 2006 with specialty eggs now making up about 5% of all eggs sold at retail. Specialty eggs like those produced in alternative production systems and enhanced in beneficial nutrients can provide a profitable opportunity for egg producers while meeting consumer demands for nutritious, safe, and humanely-produced eggs. Isoflavone-enriched eggs can be marketed as a new specialty egg that would offer a valuable source of health-promoting isoflavones, nutrients that are typically lacking in diets of Western culture. Equol, a potent soy isoflavone is found naturally in eggs of laying hens and can …

Endocrine Control Of Ovulation And Coordination Of Fetal And Uterine Interrelationships In Dairy Cattle, Jillian Fain

All Dissertations

Assessing pitfalls in reproductive efficiency of dairy cattle is often confounded by milk production, animal health, energy balance, and animal management practices, among others. Methods to reduce inefficiencies are classified in the following studies as maternal endocrine management, conceptus recognition, and uterine environment. The goal was to derive some insight into the mechanisms pre and post conception that can alter rates of pregnancy establishment. The initial study ascertained the ability to reduce progesterone (P4) dominance through additional PGF2-alpha (PGF) supplementation on efficiency of timed artificial insemination (TAI) in the Ovsynch® program. The single PGF animals received the standard Ovsynch® protocol …

The Racial Rhetoric Of Cuteness As Decorative Decorum, Nicole Mcfarlane

All Dissertations

This work looks at the trope of cuteness as a means of investigating the topological phenomena of race and public space, particularly in regards to African American rhetorical modes of visual and spatial practice. By introducing a sociological coinage known as the 'teddy-bear effect,' this work explores how racialized expressions of cuteness give off the impression of a demurring civility surrounding the social expectations associated with the cultural norms of gender and class. As a preferred characteristic of information design and strategically deployed for the tactic of racialized passings in the face of increasingly regulated forms of 'post-racial' gate-keeping and …

Nature-Based Recreationists' Perceptions Of Climate Change And Attitudes Towards Climate Change Mitigation In Natural Environments, Matthew Brownlee

All Dissertations

Novel biophysical impacts from a rapidly changing climate are influencing resources in many parks and protected areas that host nature-based recreation. In addition to climate impacts, renewable energy initiatives (e.g., wind farms) aimed to mitigate climate change are increasingly converging with nature-based recreation areas. Climate impacts and climate change mitigation efforts in nature-based recreation areas have the capacity to influence individual and collective experiences, attitudes, and potentially behaviors. However, little is known about nature-based recreationists' interactions with climate-influenced resources, and how these interactions may influence perceptions of climate change and attitudes towards mitigation efforts. This dissertation addresses this lack of …

Timing Of Exposure To Toxic Tall Fescue: Effects On Beef Cattle Reproduction, Matthew Burns

All Dissertations

Tall fescue [Schedonorus phoenix (Scop.) Holub] is a native grass of Europe and was not widely used in the U.S. until the early to mid 1900's. Toxic tall fescue (E+) is the predominate, cool-season forage used in beef cattle production in the southern U.S., but grazing this forage is known to negatively impact growth and may impair reproductive performance. Two- and 3-yr old (young) beef cattle respond differently to synchronization protocols and have higher energy requirements compared with mature cows under normal management conditions. Interestingly, limited data indicate that young cattle reproductive performance is negatively impacted to a greater extent …

Quantitative, Spatial Imaging Based Measurements To Assess Cellular Health And Oxygenation In A Tissue Engineered Test System, Erik Bland

All Dissertations

Three-dimensional in vitro tissue test systems are employed to examine cell behavior, test responses to drugs and vaccines, and answer basic biological questions. These systems are more physiologically relevant than two-dimensional cell cultures, and are more relevant, easier and less expensive to maintain than animal models. However, methods used to measure cell behavior and viability have been developed specifically for two-dimensional cell cultures or animal models, and are often not optimally translated to three-dimensional in vitro test systems. The purpose of this work was to aid in the development of three-dimensional, spatially controlled in vitro test systems, and to develop …

Nanopillar Based Electrochemical Biosensor For Monitoring Microfluidic Based Cell Culture, Rajan Gangadharan

All Dissertations

In-vitro assays using cultured cells have been widely performed for studying many aspects of cell biology and cell physiology. These assays also form the basis of cell based sensing. Presently, analysis procedures on cell cultures are done using techniques that are not integrated with the cell culture system. This approach makes continuous and real-time in-vitro measurements difficult. It is well known that the availability of continuous online measurements for extended periods of time will help provide a better understanding and will give better insight into cell physiological events.
With this motivation we developed a highly sensitive, selective and stable microfluidic …

Bioengineering Approach To Understanding Tmj Pathobiology, Jonathan Kuo

All Dissertations

The temporomandibular joint (TMJ) is a load-bearing joint consisting of the condyle of the mandibular bone, the fossa eminence of the temporal bone, and a fibrocartilaginous disc held in between the bone surfaces by ligaments. The TMJ disc serves to distribute stress, lubricate movement, and protect the articular surfaces of the joint. Over ten million Americans suffer from TMJ disorders (TMD) that affect the movement and function of the joint, making everyday tasks like talking and eating difficult and painful. A wide variety of treatments and surgeries have been proposed and undertaken with limited success based on the varying degree …

Concentration And Separation Of Lipids From Renewable Resources, Lance Beecher, David E. Brune

Clemson Patents

Disclosed are methods that can advantageously utilize the natural consumptive and conversion processes of an aquatic organism culture system to concentrate and separate microbial plant-generated lipids. For instance, an aquatic organism culture can be maintained and/or grown upon an algal biomass. The natural conversion processes of the animals allows for uptake and processing of the components of the algal biomass into animal lipid. The aquatic animal culture can then be easily harvested such that a high percentage of the converted algal-generated lipid can be extracted using a low cost, simple and quick process. The disclosed processes provide an efficient oil …

Choline Supplementation And Dna Methylation In The Hippocampus And Prefrontal Cortex Of Rats Exposed To Alcohol During Development, Nicha K H Otero, Jennifer D. Thomas, Christopher Saski, Xiaoxia Xia, Sandra Kelly

Publications

BACKGROUND:

Some of the most frequent deficits seen in children with fetal alcohol spectrum disorders (FASD) and in animal models of FASD are spatial memory impairments and impaired executive functioning, which are likely related to alcohol-induced alterations of the hippocampus and prefrontal cortex (PFC), respectively. Choline, a nutrient supplement, has been shown in a rat model to ameliorate some of alcohol's teratogenic effects, and this effect may be mediated through choline's effects on DNA methylation.

METHODS:

Alcohol was given by intragastric intubation to rat pups during the neonatal period (postnatal days 2 to 10) (ET group), which is equivalent to …

Predicting The Physiological Performance Of Ectotherms In Fluctuating Thermal Environments, Michael W. Sears, A C. Niehaus, M J. Angilletta, C E. Franklin, R S. Wilson

Publications

Physiological ecologists have long sought to understand the plasticity of organisms in environments that vary widely among years, seasons and even hours. This is now even more important because human-induced climate change is predicted to affect both the mean and variability of the thermal environment. Although environmental change occurs ubiquitously, relatively few researchers have studied the effects of fluctuating environments on the performance of developing organisms. Even fewer have tried to validate a framework for predicting performance in fluctuating environments. Here, we determined whether reaction norms based on performance at constant temperatures (18, 22, 26, 30 and 34°C) could be …
