The Integration Of 18th And 19th Century Subsistence Farming Practices Into The Planning And X-Zoning Laws Of The City And County Of Baltimore, Clayton A. Hayes Dec 2013

The Integration Of 18th And 19th Century Subsistence Farming Practices Into The Planning And X-Zoning Laws Of The City And County Of Baltimore, Clayton A. Hayes

Masters Theses, 2010-2019

The Industrial Revolution divorced the majority of urban dwellers from the land in the United States. Today, people rely upon industrial food products from global food systems. These systems cause environmental pollution, land degradation, and loss of biodiversity. Additionally, there is unequal food distribution in these systems with poor farmers growing for production and not consumption. The rigid distribution system through grocery stores often leaves poor economic areas without access to fresh, healthy food. The solution to these problems is a return to local food systems, where people can grow or have access to fresh, local food. However, local food …

Spatial Analysis Of Air Velocity Distribution As Affected By House Size And Design In Commercial Broiler Production Facilities, Brian David Luck Dec 2013

Spatial Analysis Of Air Velocity Distribution As Affected By House Size And Design In Commercial Broiler Production Facilities, Brian David Luck

Theses and Dissertations

Tunnel ventilation is the design practice of placing exhaust fans and air inlets on opposite ends of animal production facilities and moving air through the building via negative pressure. Increasing air velocity within tunnel ventilated broiler production facilities increases sensible cooling and reduces the need for latent cooling (panting), which improves production efficiency. An air velocity measurement system was developed and measurement density analysis for quantifying air velocity distribution was performed in a 12.19 x 121.9 m commercial broiler production facility. Results showed that axial measurement distances of 3.05 m and 40 measurement points per cross-section produced the most descriptive …

Determining A Developmental Window For The Effect Of Polychlorinated Biphenyl (Pcb) On Ultrasonic Vo, Hannah Duffy Dec 2013

Determining A Developmental Window For The Effect Of Polychlorinated Biphenyl (Pcb) On Ultrasonic Vo, Hannah Duffy

Honors Projects

Commercial manufacturing and widespread use of polychlorinated biphenyl (PCB) in the United States has left lasting negative effects today. These persistent contaminants continue to bioaccumulate in the food web because of their stable structure, long half-life, and high lipophilicity. Adding PCB to the diet of Sprague-Dawley rats during pregnancy and lactation alters the thyroid status of offspring, and the behavior of the dams and pups. To determine a critical period or “window” of development with the greatest impact of PCB exposure of females on offspring fitness, female Sprague-Dawley rats were mated and fed PCB diet (25 ppm PCB 47 and …

Analysis Of Morphology And Fauna Of Geometrinae (Lepidoptera: Geometridae) Of The Caribbean Region, David M. Plotkin Dec 2013

Analysis Of Morphology And Fauna Of Geometrinae (Lepidoptera: Geometridae) Of The Caribbean Region, David M. Plotkin

Theses and Dissertations

The Geometrinae, commonly known as emerald moths, are a diverse group of Lepidoptera with over 450 Neotropical species. However, Caribbean Geometrinae have received relatively little attention compared to the Geometrinae of mainland Central and South America. Using the method of Lee and Brown (2006), whole body mounts of descaled specimens of both Caribbean and mainland Neotropical Geometrinae were prepared. Morphological variation of exo- and endoskeletal characters among species, genera, and tribes of Neotropical Geometrinae is described. A faunistic study of Caribbean Geometrinae was also conducted using material from museums and private collections. The study includes definitions of species of Caribbean …

Determination Of Beta-Carotene Content And Consumer Acceptability Of Sweet Potato Cookies By Adults And Preschool Children, Aja Marie Stokes Dec 2013

Determination Of Beta-Carotene Content And Consumer Acceptability Of Sweet Potato Cookies By Adults And Preschool Children, Aja Marie Stokes

Theses and Dissertations

Vitamin A deficiency is recognized as a major health concern worldwide, especially in developing countries. Sweet potatoes are a cash crop that is abundantly grown and available, providing an excellent source of the carotenoid, beta-carotene. Carotenoids are precursors to vitamin A (retinol). Three sweet potato cookie products were developed: glutenree, wheat-containing, and glutenree with extra sweet potato. Products were evaluated by adults and pre-school aged children based on appearance, aroma, texture, flavor, and overall acceptability. Results showed that overall the children liked both the glutenree and wheat-containing cookies (p<0.05). Adults preferred (p<0.05) the glutenree with extra sweet potato and the wheat-containing products. The glutenree cookie contained 10.1 parts per million of beta-carotene as determined by high-performance liquid chromatography.

Differentiating The Characteristic Response Of The Brain After Exposure To Blunt And Blast Trauma, Mark Gregory Tejada Begonia Dec 2013

Differentiating The Characteristic Response Of The Brain After Exposure To Blunt And Blast Trauma, Mark Gregory Tejada Begonia

Theses and Dissertations

Military personnel often experience mild traumatic brain injury (mTBI) from exposure to improvised explosive devices (IEDs). Soldiers typically endure blast trauma from the IED pressure wave as well as blunt trauma from ensuing head impacts. Researchers have not reached a consensus on whether the biomechanical response from blunt or blast trauma plays a more dominant role in mTBI because the specific biomechanical sources of injury are often undetermined. Consequently, the goal of this dissertation was to conduct three separate studies in order to characterize the mechanical behavior of the brain after exposure to mTBI conditions. For Study 1, mild blunt …

Meta-Heuristic Optimization Of Antennas For Biomedical Applications, Aaron Zachary Hood Dec 2013

Meta-Heuristic Optimization Of Antennas For Biomedical Applications, Aaron Zachary Hood

Theses and Dissertations

Given the proper conditions, antennas applied in medicine can offer improved quality of life to patients. However the human body proves hostile to typical, analytical antenna design techniques as it is composed entirely of frequency- and temperature-dependent lossy media. By combining optimization techniques with numerical methods, many of these challenges may be overcome. Particle swarm optimization (PSO) models the solution process after the natural movement of groups such as swarms of bees as they search for food sources. This meta-heuristic procedure has proven adept at overcoming many challenging problems in the electromagnetics literature. Therefore, this dissertation explores PSO and some …

Impact Of Oxidative Stress On Female Fertility., Tasha Harris Dec 2013

Impact Of Oxidative Stress On Female Fertility., Tasha Harris

Undergraduate Honors Theses

This study examined nutritional status and fecundity of women and was approved for patient enrollment by the ETSU Institutional Review Board (IRB). Once enrolled, participants filled out two food frequency questionnaires (FFQ, fruit/vegetable intake, fat intake), self-reported anthropometric data, and had one 5 mL vacutainer of whole blood (EDTA) collected for measures of oxidative stress (OS), coenzyme Q10 level, and fatty acid profile of the red blood cell (RBC) membrane. Participants were either designated to the case group (13 women experiencing fertility problems and an anti-mullerian hormone level of 1 ng/ml or less (AMH, <1 ng/mL)) or the control group (13 women experiencing normal ovulation cycles and no evidence of polycystic disease). This study hypothesized that the case group would have poorer plasma antioxidant status, consume more dietary saturated fat and have lower levels of omega-3 and higher levels of omega-6 fatty acids in the RBC membrane. Results showed that case participants had significantly higher body mass index (BMI) when graduating from high school, BMI upon enrollment in the study, and trended to gain more weight since high school. Antioxidant status of the plasma tended to be higher for the case group. This result was surprising as case participants consumed significantly fewer servings of fruits and vegetables (sources of antioxidants) than control subjects. FFQ results indicated that case participants consumed significantly higher amounts of total fat (g), saturated fat (g), unsaturated fat (g), and their diets had a higher dietary fat percent. No significant differences were noted in the individual fatty acids isolated from the RBC membrane or in calculated ratios of fatty acid between case and control groups. The fatty acid profile from RBC membranes are in agreement with self-reported fat intake from FFQ data and may provide a rationale for no differences observed between the two groups.

Effects Of Nurr1 Genotype And Aging On Dopamine Neurotransmission And Behavior, Evangel Kummari Dec 2013

Effects Of Nurr1 Genotype And Aging On Dopamine Neurotransmission And Behavior, Evangel Kummari

Theses and Dissertations

Nurr1 is a transcription factor essential for the establishment, development, terminal differentiation and maintenance of mesencephalic dopamine neurons. Nurr1 is thought to coordinate the expression of dopamine neurotransmission genes. Nurr1-null heterozygous (+/-) mice have reduced Nurr1 function, which impacts dopamine neuron function in a region specific manner. Since aging can affect Nurr1 expression, we hypothesize that aging and +/- genotype will have significant effects on dopamine regulation and dopamine related behaviors. To test this hypothesis, regional neurochemistry and behavioral tests of wild type (+/+) and +/- mice at 3 months of age (young) and 12-16 months of age (aged)was performed. …

Dispersal And Management Of Invasive Aquatic Plants In Mississippi Waterways, Amanda Louise Fernandez Dec 2013

Dispersal And Management Of Invasive Aquatic Plants In Mississippi Waterways, Amanda Louise Fernandez

Theses and Dissertations

To understand the flow of water as a factor that influences aquatic vegetation communities and aquatic plant dispersal, custom-made Global Positioning System (GPS) drones were used to monitor the movement of water in Aliceville Lake, Columbus Lake, and Ross Barnett Reservoir, MS. In each reservoir, the drones drifted in the wind-generated surface current. Analysis of wind speeds suggests that a certain wind speed may be necessary to overcome gradient flow. Wind direction and wind speed should be incorporated in future spatial simulation models for aquatic plant dispersal and distribution. An herbicide evaluation on Cuban bulrush (Oxycaryum cubenese) was conducted to …
