Testing The Efficiency Of Vertically Aligned Gold Nanowires On A Titanium Needle Implantable Neural Electrodes In The Rattus Norvegicus Hippocampus, Lauren Kegley

Electrical Engineering Undergraduate Honors Theses

Miniaturized multi-electrode arrays are MEMS devices that have found use as neural prosthetics (Neuro-MEMS). As implants they can interface with neurons as sensors or actuators and help compensate for loss of sensory input, motor control, or cognitive function. The micro-electrodes, studied here, were developed in-house. They have a vertically aligned gold nanowire array and are mounted on a sturdy fine gauge titanium needle. Hence, the bill of materials and design characteristics encourage its use as neural probe. For this study, a probe was tested in vivo for signal acquisition in the hippocampus of a Rattus Norvegicus (Sprague Dawley Rat). Using …

Integrating Human Variables In Cross-Boundary Monitoring Of Aberdare Preserves In Kenya, Peter K. Njuguna

Graduate Theses and Dissertations

This research critically examines extant data systems and their linkage of scientific research to policy and public education in east African highland forest conservation preserves. The research indicates that the current state of data and monitoring systems in the region imposes substantial limitations on the ability to manage these preserves. Major outcomes of those constraints manifest in unprecedented cross-boundary pressure such as encroachment and conversion of forest to agriculture, increased human-wildlife conflicts, and constrained relations among primary stakeholders. Current monitoring is biodiversity focused within preserves and fails to capture human dimensions in adjoining areas across preserve boundaries. This study proposes …

Pixel; Ghost, John Christopher Kelley

Graduate Theses and Dissertations

Pixel; Ghost is an exhibition of video and sound installations that explore the creation, change, and degradation of memory, transitional states of mind, and family. The pieces are structured around cinematic clichés such as dream sequences, flashbacks and establishing shots, using them as a language to translate personal experience into something more universal.

In my work, Pixel refers to the individually active component of a larger system. A pixel itself changes and has its own characteristics, though these are ultimately subservient to its role in the larger system of a screen. The purpose and meaning of a pixel comes not …

Dental Microwear Texture Analysis Of Pliocene Bovids From Four Early Hominin Sites In Eastern Africa: Implications For Paleoenvironmental Dynamics And Human Evolution, Jessica Renee Scott

Graduate Theses and Dissertations

Many researchers have suggested that Plio-Pleistocene climate change was a motive force for human evolution. The basic idea was that a shift toward drier, more open settings, led to adaptations for bipedality and the consumption of savanna resources, including large grazing mammals. However, more recent paleoenvironmental reconstructions suggest that Pliocene hominins occupied variable or mosaic habitats including both open and closed settings. Many techniques have been used to refine our understanding of the paleoenvironments of eastern Africa; however these have not led to consensus reconstructions. At Kanapoi, ecological diversity analysis indicates that at least part of the site was composed …

Cornography: Perverse Incentives And The United States Corn Subsidy, Anthony Kammer

Journal of Food Law & Policy

Among the most important functions we have afforded to the U.S. Congress is the power to reshape social and economic incentive structures through legislation. Proceeding from the enumerated powers under the Constitution and using a complex toolbox of legislative and regulatory innovations, the federal legislature has enormous power to transform the types of behavior that people will perceive as self-interested throughout our economy and thus how those same people are likely to act. Congress can, among other things, create new forms of criminal and civil liability, establish entitlement systems, subsidize industries, encourage behavior through the tax code, regulate interactions among …

The Evolution Of Rural Farming In The Scottish Highlands And The Arkansas Delta: Investments And Inequalities, Madalyn Watkins

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

The development and evolution of an agricultural system is influenced by many factors including binding constraints (limiting factors), choice of investments, and historic presence of land and income inequality. This study analyzed the development of two farming systems: mechanized, “economies of scale” farming in the Arkansas Delta and crofting in the Scottish Highlands. The study hypothesized that the current farm size in each region can be partially attributed to the binding constraints of either land or labor. In Scotland, it was found that the continuous binding constraint was the availability of arable land. In Arkansas, the binding constraint began as …

Investigation Of A Locus On Chromosome 9 For Contributions To Pulmonary Hypertension Syndrome In Broilers, Sriram Krishnamoorthy

Graduate Theses and Dissertations

Although the ascites syndrome in chickens has been investigated for years, it continues to inflict financial losses to the world poultry industry. It is estimated that 8% of the 361 million broiler deaths are due to ascites leading to losses of millions of dollars annually. Efforts to curb the incidence of ascites are typically designed to slow early growth. This limits the birds' ability to show its true genetic potential and impacts later yields. In 1994 lines divergent for susceptibility to ascites were established from a commercial sire line through sibling selection of birds reared at local altitude after testing …

A Comparative Analysis Of Free Trade Between The U.S. And The Eu : A Case Study Of The U.S./Chile Fta And The Eu/Chile Fta, Misti Dawn Sharp

Graduate Theses and Dissertations

Unlike many studies that assess the impacts of free trade agreements (FTAs), this thesis is a study of the negotiated outcomes in FTAs between the United States (U.S.) and Chile, and the European Union (EU) and Chile. Existing negotiation literature pertains to multilateral trade talks, dispute settlements or bilateral one good trade agreements. Studies regarding the negotiation process and other factors influencing outcomes in comprehensive FTAs are rare. In order to address this gap in the literature, this thesis is an analysis of how and why the FTA between Chile and the U.S. differs from the FTA between Chile and …

The Truth Between The Teeth: An Analysis Of Interproximal Tooth Wear At The Ables Creek Cemetery, Amy Reynolds Warren

Graduate Theses and Dissertations

Current archaeological knowledge suggests that, by the Late Mississippian period, inhabitants of the southeastern United States had adopted maize agriculture and that maize was a key component of the normal diet. However, in some regions where wild food resources were easily attainable, there is evidence that the transition to agriculture was delayed or did not occur at all. This thesis examines Late Mississippian skeletal collections from two sites in eastern Arkansas, Ables Creek and Upper Nodena. Analysis of differences in interproximal tooth wear facet size and caries rates between the two populations reveals that the diets at these roughly contemporary …

Characterization Of Novel Histone H2b Mutants Associated With Chromosome Segregation Defects In Saccharomyces Cerevisiae, Thiruchelvam Rajagopal

Graduate Theses and Dissertations

Histones are small basic proteins that associate with DNA to form the basic unit of chromatin, the nucleosome. Histones H3 and H4 form a tetramer that is bound by two H2A-H2B dimers to form the histone octamer, to which approximately 146 bp of DNA wrap around to form the nucleosome. High resolution structural information and recent advances in the understanding of histone post-translational modifications have illuminated the many regulatory functions chromatin exerts in the cell, from the transcriptional control of gene expression to chromosome segregation. However, the specific role that histones play in these processes is not well understood. Previous …

The health benefits and the nutritional values of soyfood products have expanded the demand for food-grade soybean varieties. For whole soyfood products such as natto, small seeded varieties with proper texture are essential. Seed calcium content and hardness are main factors in determining the seed texture. Utilizing molecular markers associated with quantitative trait loci (QTL) for marker assisted selection (MAS) has been an efficient technique for breeders. To find molecular markers associated with a trait is an initial step. The confirmation of QTL in different environments and in different genetic backgrounds is important for MAS. The objectives of this research …

The Effect Of Natural Antioxidants On Cla Yield During The Photoisomerization Of Soy Oil Linoleic Acid, Camille Schaffner

Food Science Undergraduate Honors Theses

Dietary conjugated linoleic acid (CLA) is known to be effective in avoiding many obesity related diseases. Conjugated linoleic acid is a product of ruminant fermentation and 3.4g/day are needed to obtain the clinical benefits. However, it is difficult to obtain sufficient CLA to realize these benefits from a healthy diet containing dairy and beef products, without increasing levels of dietary cholesterol and saturated fat. A 20% CLA soy oil with low saturated fat and no cholesterol has been produced by the photoisomerization of linoleic acid in the triacylglyceride oil. Further increasing the CLA yields has been possible by addition of …

Exploring The Differences Of The Grocery Experience Between Spain And The United States: Is It More Than Just Potato, Patata, Tomato, Tomate?, Madison Dowell

Marketing Undergraduate Honors Theses

With the increasing globalization of the world economy, companies looking to take part in this trend must pay attention to the differences between aspects of their home country and the country in which they are trying to sell products. Being well informed on criteria that could affect the purchase decision of foreign consumers is essential to avoiding self reference criterion and ethnocentrism, or the unconscious referral to and focus on one’s own culture rather than the targeted culture. “Sociologic differences around the world largely outweigh the similarities. People in the global community are influenced and driven by different things. Lack …

Effect Of Enzymatic Treatments On The Physiochemical Properties Of Different Corn Starches, Curtis Robert Luckett

Graduate Theses and Dissertations

Amylose readily reassociates to form films and crystalline structures that are resistant to digestion by amylolytic enzymes and known as resistant starch type III (RS3). This study investigated the RS3 formation and cereal coating properties from enzyme-modified corn starches with varying amylose contents, including Hylon VII (70% amylose), Hylon V (50% amylose), and common corn (25% amylose). For RS3 formation, corn starches were first gelatinized and then hydrolyzed using β-amylase to varying degrees. The resultant hydrolyzed starch was debranched with isoamylase and then exposed to 3 times of temperature cycling at 135/133/133°C for 30 min and 95°C for 24 hr …

Territories,Territoriality, And Conservation Of The Louisiana Waterthrush And Its Habitat, The Watershed Of The Upper Buffalo National River, Leesia Cheryl Marshall

Graduate Theses and Dissertations

The Louisiana Waterthrush, Parkesia motacilla, is a migratory wood-warbler and breeding season resident of the eastern United States. Males defend breeding territories that extend linearly along clear, fast-flowing, gravel-bottomed, forest streams. Defense includes two song types, primary and extended song. As riverine specialists, birds rely upon aquatic invertebrates as prey and riparian habitat features for nesting. They use a unique foraging maneuver, leaf-pulling, that involves picking up or pulling a leaf from water, and turning it over to search for prey. Their relationship with riparian habitat introduces potential for Louisiana Waterthrushes to serve as indicators of stream health. The …

Biological Strategies And Mathematical Approaches For Limiting Bacterial Contaminants And Chemical Pollutants In Bioethanol Fermentations, Alia Chahed Ep Limayem

Graduate Theses and Dissertations

During the most recent decades increased interest in fuel from biomass in the United States and worldwide has emerged each time petroleum derived-gasoline registered well publicized spikes in price. The willingness of the U.S. government to face the issues of more heavily high-priced foreign oil and climate change has led to more investment on plant-derived sustainable biofuel sources. Biomass derived from corn has become one of the primary feedstocks for bioethanol production for the past several years in the U.S. However, the argument of whether to use food as biofuel has led to a search for alternative non-food sources. Consequently, …

Feed Supplementation With Natural Extracts Of Cranberry And Its Efficacy On Campylobacter Colonization In Poultry, Ann Woo-Ming

Graduate Theses and Dissertations

Campylobacter spp. has been identified as one of the leading causative agents of food borne diarrheal illness. Epidemiological evidence has shown that poultry is the main source for human infection. Poultry are asymptomatic carriers of Campylobacter within their gastrointestinal tract, with colonization levels reaching 106-108 cfu/g cecal content. Surveys of domestic poultry flocks have estimated that approximately 90% of flocks are positive for Campylobacter colonization. Risk assessment studies have determined that by reducing levels of Campylobacter colonization during rearing, incidences of human infection will be significantly reduced. Currently there are no consistently effective treatments to eliminate Campylobacter from poultry flocks. …
