The Effects Of The Nat Turner Slave Revolt On The Health And Welfare Of 19th-Century Slaves In Southeastern Virginia, Jeffrey Clifford Auerbach

Master's Theses

The Nat Turner Slave Revolt stands as a major turning point in the history of American slavery and represents a fundamental shift in the master slave relationship. This event shattered the previous paternalistic view and caused a fundamental reorganization of slave life. Included in this reorganization was a shift in the subsistence practice, moving away from morenutritious food grown by the slaves themselves to poor quality rations provided by the masters. This change in subsistence practices dealt a serious blow to the nutritional health of those living in the area surrounding the revolt.

By examining stature recorded in the County …

Treatment Of Nitrogen Oxides By Chlorella Vulgaris Algae In Photobioreactors, Steven Shihady

Master's Theses

The effectiveness of algae to treat NO₂and NO in simulated flue gas was tested using Chlorella vulgaris in photobioreactors (PBRs) using NO_xconcentrations between 30 ppm to 780 ppm. NO_xdissolved and reacted in water to form NO₃^-and NO₂^-in the PBR growth medium, providing a nitrogen source that the algae readily assimilated for cell synthesis. Three 20-L photobioreactors were inoculated with a pure culture of C. vulgaris prepared in Bristol growth medium and algae were grown in the PBRs at 25°C and pH of 7.0 in a modified Bristol medium …

A Multicultural Nutrition And Culinary Intervention For Middle School Students: Pink And Dude Chefs, Phase 2, Jaime Lynn Lockhart

Master's Theses

The prevalence of adolescent obesity in the United States has more than quadrupled in the past 30 years, growing from 5% to nearly 21% in 12-19 year olds. Although obesity has many interrelated causes, a lack of knowledge and practical skill to prepare healthy food from scratch is an important factor. Research indicates that nutrition and culinary interventions based on behavioral change theories may improve mediators of healthful eating in adolescents.

Pink and Dude Chefs, Phase 2, an eight-week after-school nutrition and culinary intervention targeted towards middle school students in a predominantly low-income, Hispanic community, was developed and evaluated. The …

Effects Of Water Parameters On Container Mosquito (Diptera: Culicidae) Oviposition And Performance, Stephanie Sue Schelble

Master's Theses

Water body parameters have a considerable effect on the communities that develop within them. In small container habitats like tires, the depth, surface area, and volume effect the development and success of the mosquito communities. This study investigated the choices of the adult female mosquitoes, Aedes albopictus and Culex quinquefasciatus, between different depths and surface areas. In addition, larval performance was determined under differing depth and larvae densities. Oviposition studies showed that Ae. albopictus had a preference for deeper habitats (χ²= 14.2902, p= 0.0139) but did not prefer any surface areas (χ²= 7.2321, p= 0.0649) though …

The Effect Of Temperature And Extraction Technique On The Binding Interactions And Hydrolysis Of Β-Lactoglobulin With Milk Fat Globule Membrane (Mfgm), Corbin R. Kembel

Master's Theses

Whey protein, containing predominately b-Lactoglobulin (b-LG), is a popular choice among consumers looking for an excellent protein source. Likewise, fat is a natural component in milk and dairy products. Lipids are packaged within a membrane called the Milk Fat Globule Membrane (MFGM). The MGFM contains a variety of lipids and proteins. Although b-LG has been extensively characterized, the function of the protein is largely unknown. The objectives of this study were to assess the enzymatics of b-LG in an isolated system, evaluate the propensity of b-LG to bind to MFGM, determine the effects of temperature and fat extraction method on …

Effects Of Ovariectomy And Anatomical Position On The Compact Bone As Seen In Three Month Summer Ovine Model, Bryan C. Kraft

Master's Theses

The purpose of this study is to characterize the compact-bone remodeling response to an ovariectomy model of human postmenopausal osteoporosis. Animal models are a beneficial practice allowing for the evaluation of the effectiveness of medical therapies and devices on diseases. The ovine model was chosen for this study due to its large size, similar bone remodeling to humans, and cost effectiveness. The main obstacle to overcome with the use of the ovine model was the lack of natural menopause experienced by this species. To overcome this, it was necessary to perform an ovariectomy to create estrogen depletion and artificially induce …

Cayucos Community Health Plan, Jennifer Joyce Franich

Master's Theses

Recent, mounting research shows that chronic disease, the leading causes of death and primary driver of health care costs, cannot be effectively addressed through education or preventative health alone. A physical environment that promotes health—through access to healthy food, opportunities for physical activity, quality housing, transportation options, and safe schools—is an integral part of making our communities healthier. This research and accompanying Healthy Community Plans will serve as a way for the County to begin looking in-depth at the ways the built environment (our streets, parks, and neighborhoods) contribute or detract from the health of the community. Though the creation …

Optimization Of Growth Parameters For Algal Regrowth Potential Experiments, Chadwick D. Boggess

Master's Theses

Water cost is one of the key deterrents in making algal biofuels a feasible alternative to traditional petroleum fuels. Research into recycling of algal media was conducted in a laboratory setting at the California Polytechnic State University in San Luis Obispo. A growth assay was created to allow for algal cultures, specifically Ward’s Chlorella sp., to proliferate in sealed culture vessels. Bold’s Basal Medium (BBM) was selected as the media due to its extensive use with freshwater algal strains. However, this medium can limit algal growth through nutrient limitation and it became necessary to augment the original recipe. 50mM …

Recognizing Specific Errors In Human Physical Exercise Performance With Microsoft Kinect, Ryan Staab

Master's Theses

The automatic assessment of human physical activity performance is useful for a number of beneficial systems including in-home rehabilitation monitoring systems and Reactive Virtual Trainers (RVTs). RVTs have the potential to replace expensive personal trainers to promote healthy activity and help teach correct form to prevent injury. Additionally, unobtrusive sensor technologies for human tracking, especially those that incorporate depth sensing such as Microsoft Kinect, have become effective, affordable, and commonplace.

The work of this thesis contributes towards the development of RVT systems by using RGB-D and tracked skeletal data collected with Microsoft Kinect to assess human performance of physical exercises. …

The Effect Of Pretreatment Methods On Methane Yield And Nutrient Solubilization During Anaerobic Digestion Of Microalgae, Alexander Scott Hill

Master's Theses

Microalgal biomass is a candidate feedstock for biofuel production. To improve the sustainability of algae biofuel production, following biofuel recovery, the biomass nutrients should be recycled for additional algae growth. Anaerobic digestion of algae or oil-extracted algae is a means of recovering carbon and other nutrients, while offsetting algae production electricity demand. The major limiting factor in microalgae digestion is the low biodegradability of the cell walls. In the present study, various pretreatment technologies were tested at bench scale for their ability to improve raw, non-lipid-extracted algae biodegradability, which was assessed in terms of methane yield, volatile solids destruction, and …

An Examination Of An Environmental Change In Beverages Available To High School Students In Santa Maria, California On Their Consumption Behavior, Susan Eileen Klucker

Master's Theses

Hypothesis: "By an environmental change in high school vending machines, making water available, students will choose water over the sugar sweetened sodas."

This document highlights a case study analysis of vendor-provided refill data for forty-five beverage vending machines at two campus sites in one high school district in 2003 and 2004. The innovative study and publicized negotiated soda contract of a 50:50 (healthy to unhealthy) beverage ratio stipulation became the “Win-Win-WEAN” compromise, in which exposure to healthier beverage options for students might prove to provide the same income opportunity for the school district.

An overview of the political …

With this in mind, it has become imperative to identify product attributes that drive consumption so they can be replicated in …

Development Of Novel Anti-Microbial Plant Essential-Oil Treatments To Reduce The Postharvest Incidence Of Botrytis Cinerea Of Strawberries, Ryan C. Brantley

Master's Theses

Fresh strawberries have grown into a multi-billion dollar industry over the last few decades in California. Botrytis cinerea or grey mold, is the worst pathological disorder affecting strawberry fruit causing cull rates of up to 30% in the worst seasons. Strawberry fruits are fragile and have a short shelf-life making timely harvest, cooling, and marketing an absolute necessity. The current industry standard is to ship strawberries in an overwrapped CO₂-enriched headspace pallet in refrigerated trucks at 33 °F. However, B. cinerea has the ability to grow at very low temperatures and continues to plague the strawberry industry during postharvest storage …

Typhoons And Lower Birth Weight In The Philippines, Sarah Morrow

Master's Theses

Do typhoons impact birth weights of infants exposed to a typhoon while in utero? This research exploits the exogeneity and randomness of typhoons in the Philippines to estimate the impact of typhoon exposure as determined by wind speed on birth weights. Using four waves of the Demographic and Health Survey (DHS) data from the Philippines combined with temperature, precipitation, and rainfall data from the Philippines, I can empirically estimate the impact of a 1 m/s increase in wind speed on birth weights. I find that for certain subgroups of the population, specifically children born to mothers with primary education or …

Matrilineal Asset Inheritance, Female Bargaining Power, And Household Welfare In Malawi, Nicholas T. Garcia

Master's Theses

Matrilineal inheritance practices in Malawi exogenously determine female land holdings at the time of marriage, allowing for the identification of the effect of increased female bargaining power on household consumption decisions. I use the matrilineal ethnicity of the head of household as an instrument for the share of total household land inherited by the female head or male head’s wife. I find that child’s height-for-age decreases with female assets, and evidence suggesting increased consumption from households’ own production. Since the food basket from own consumption is high in carbs but not nutritious, long-term child health suffers despite receiving more resources …

Impact Of Typhoons On Children's Human Capital Investments In Filipino Households, Kate Zitelli

Master's Theses

Typhoons are a unique type of natural disaster affecting both developing and developed countries, causing both short and long-term destruction. Typhoons are random both in intensity and frequency, making them difficult to predict their strength and when they will strike. With global climate change, typhoons are expected to increase in both frequency and magnitude, making it important to understand their impacts. This study uses DHS data from the Philippines and a unique Filipino typhoon data set covering they years 1989-2008 to explore how typhoons affect household allocation of basic human capital investments, such as breastfeeding duration. Using OLS estimation and …

The Stress Response To An Acute Heavy Resistance Exercise Protocol, Adam J. Sterczala

Master's Theses

Exercise has been shown to induce significant stress and a subsequent inflammatory response characterized by changes in circulating leukocyte populations and inflammatory cytokines and has been well documented following aerobic exercise. Research in regards to the effects of resistance exercise on the stress induced inflammatory response is less prevalent and has shown divergent results, likely due to differences in the exercise protocols used, the time points measured and the subjects involved. Therefore, the purpose of this investigation was to analyze the stress response to an acute heavy resistance exercise protocol (AHREP) in resistance-trained men. Specifically, we examined effects on circulating …
