Cell phone performing a normal Google search, the battery drains very fast. The reason is that when sending a query to and fetching the results from Google, cell phone keeps communicating …

Gene Expression And Physiological Analyses To Study Metabolic Shifts In Medicago Truncatula Subjected To Biotic Stresses, Michelle Ryan Martin

Graduate Theses and Dissertations

Plants are frequently under attack from pests and deploy various defense mechanisms to fight off predators. Many plant defenses are induced following herbivory or pathogen infection. An investment in defense could potentially lead to a diversion of metabolic resources away from primary metabolism, including reduction in plant commitment to photosynthesis. In this thesis, changes in expression levels of representative genes for primary and secondary metabolism were studied using real-time polymerase chain reaction (PCR) in Medicago truncatula Gaertner subjected to beet armyworm (Spodoptera exigua H¨¹bner) damage or Phoma medicaginis Malbr. & Roum. infection. Photosynthetic yield was also measured using chlorophyll fluorescence …

Perception Of Aquifer Depletion And The Effects Of Land Use Change Across The Madaba Plain, Jordan, Mohammad Salem

Graduate Theses and Dissertations

In Jordan, demand for water for agricultural purposes has put a high strain on aquifer resources. Water mining, erosion, and desertification have all increased as global temperatures rise. This along with fragmentation of the landscape have altered the environment in a profound way. The Madaba Plain was chosen for this study due to the agricultural activities that take place there, as well as the proximity to a number of population centers. The purpose of the study is to examine how fragmentation of irrigated landscape has affected the aquifers underneath, while taking into account perceptions of risk of the local population. …

Can Antioxidant-Rich Berries Improve Risk Factors Associated With Cardiovascular Disease In Postmenopausal Smokers?, Jordan Alaine Teeple

Graduate Theses and Dissertations

The purpose of this study was to examine the effects of smoking on risk factors associated with cardiovascular disease (CVD) and determine the efficacy of antioxidant-rich berries in ameliorating these risk factors in postmenopausal smokers. Menopause and cigarette smoking have been identified as major risk factors for CVD due to a decrease in antioxidant protection, increase in inflammation and oxidative stress, and adverse changes in serum lipids. Antioxidants, specifically flavonoid compounds found in blackberries and blueberries, have been shown to prevent low-density lipoprotein cholesterol oxidation and thus prevent downstream inflammation and oxidative stress. Healthy, postmenopausal nonsmokers (n=14) and smokers (n=31) …

World Languages, Literatures and Cultures Undergraduate Honors Theses

Through the examination of the interactions between modern and alternative healthcare practices in five Latin American countries (Peru, Ecuador, Chile, Mexico, and Cuba), this thesis explores the strengths of a variety of indigenous medical practices while laying the foundation for building bridges to the modern medical establishment in the United States as a means to benefit the health of both immigrants and native citizens.

Visualizing The Spatial Localization Of Active Matrix Metalloproteinases (Mmps) Using Maldi Imaging Ms, Sasirekha Muruganantham

Graduate Theses and Dissertations

Biomaterial implantation induces the foreign body response (FBR). Development of longer-term implants relies on the thorough understanding of the FBR. The progression of the FBR is regulated by a number of biomolecules including cytokines, chemokines, and matrix metalloproteinases (MMPs). The nature of the FBR requires the spatial and temporal regulation of these mediators. MMPs are an extremely large and diverse group of enzymes that play key roles in regulating the FBR. Precise spatiotemporal regulation of MMPs defines their proteolytic activities. The aim of this project is to develop a new bioanalytical method to visualize the localization of active MMPs at …

Participants (n=7) included master's level counselors-in-Training (CITs), all female, and ranging in age from 23 to 44. Data generated by the formal interviews gained support for using mandalas as a creative approach in triadic supervision as they revealed the potential to impact the working alliance and the goals, task, and bond therein. Of further importance was the finding that the bond between paired CITs in triadic supervision sessions was also impacted by the …

A Nietzschean Account Of Human Flourishing: Affirming The Will To Power Inside The Contours Of Friendship, Christian Joshua Roos

Graduate Theses and Dissertations

In this dissertation, I examine Friedrich Nietzsche's notion of the will to power, his account of friendship and his understanding of human flourishing. Through textual analysis, I offer a new way of interpreting the will to power, as the achieving of self-realization. The process of achieving self-realization is undergirded by the satisfaction of seven existential needs that are rooted in the paradoxical human conflict between instincts and consciousness. The existential needs are the need for a frame of orientation, the need for devotion, the need for unity, the need for rootedness, the need for stimulation, the need for effectiveness and …

Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt

Graduate Theses and Dissertations

The impacts of an April 2007 spring freeze event on the productivity of deciduous broadleaf forest were analyzed using geographic information system (GIS) tools. Forest productivity was modeled using the Enhanced Vegetation Index (EVI), as recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor. Measures of spatial autocorrelation were used to quantify the degree of spatial congruence between a map depicting the severity of the freeze event, and maps modeling forest productivity throughout the year. The results show a geographic correlation between the unseasonably low minimum temperatures sustained during the freeze and the unusually low forest productivity that followed. …

Muslim Women And The West: Faith, Feminism, And The Quest For Gender Equality, Kelly Haller

Graduate Theses and Dissertations

For centuries the West has seen the Muslim woman as an entire group of people in need of saving. Lacking a thorough understanding of Islam and an incredibly diverse Middle Eastern society, Western powers endeavored to shape women of the Middle East into secular, modern examples of "liberated" women. Completely unacknowledged in this pursuit are the grass roots movements that emerged out of nationalist movements in the early twentieth century. An attempt to understand why the West is so incredibly fascinated by Muslim is undertaken in this scholarly pursuit. Additionally, a case study on the nation of Egypt shows not …

Detection Of Two Pathogens Of High Importance To The National Poultry Improvement Plan: Salmonella Spp. And Mycoplasma Spp., Robin Levi Jarquin

Graduate Theses and Dissertations

In 1935, the National Poultry Improvement Plan (NPIP) was created to control Salmonella gallinarum and Salmonella pullorum . These two pathogens were devastating economically for poultry producers. Through cooperative efforts using vaccination and strict biosecurity, these two pathogens were eradicated from the United States. Currently, the NPIP program is targeting two other poultry pathogens, Salmonella enterica serovar Enteritidis and Mycoplasma . In the broiler industry it targets 2 specific Mycoplasma species (synoviae, gallisepticum). Vaccinations for these bacteria are available, but are not fully effective at controlling all strains and serovars. Thus, constant monitoring systems and strict biosecurity measures are necessary …

Subcritical Water Hydrolysis Of Whey Proteins, Ashley Dawn Espinoza

Graduate Theses and Dissertations

Hydrolyzing food by-products is a unique approach to potentially increase by-product value and reduce waste. An abundant by-product of cheese production, whey, contains all essential amino acids and some distinctive peptides with functional and nutraceutical properties. Typically, proteins from whey are tailored for specific uses by chemical or enzymatic hydrolysis; however, subcritical water hydrolysis is a novel alternative used successfully to hydrolyze various substrates. Nevertheless, minimal research exists on: (1) the hydrolysis of whey protein; (2) the incorporation of additives; (3) the hydrolysis of whole whey; and (4) the production of volatiles when using subcritical water hydrolysis.

Therefore, whey protein …

Effect Of Supplemental Trace Mineral Source (Organic Versus Inorganic) On Bull Semen Quality, Matt Rowe

Graduate Theses and Dissertations

Studies indicate that organic forms of trace minerals can improve cow reproductive performance, particularly during periods of stress. However, limited information is available on the effects of organic trace mineral supplementation on bull fertility. The objective of this study was to evaluate the effect of organic versus inorganic trace mineral supplementation on bull semen quality before and after freezing, as measured by computer-assisted sperm analysis (CASA). Angus and Balancer bulls were assigned to inorganic (n = 9) and organic (n = 10) trace mineral treatments, based on initial semen quality, breed, body weight, and age. The bulls were maintained in …

Earthworms Of Arkansas And Contributions Of Earthworm Evolutionary Origin And Ecological Group To Nitrogen Cycling In A Model Soil And Tall Fescue System, Peter John Tomlinson

Graduate Theses and Dissertations

Evolutionary origin and ecological niche may impact how earthworm species affect N cycling. Tall fescue (Lolium arundinaceum (Schreb) S. J. Darbysh) infection with the toxic endophyte Neotyphodium coenophialum Glenn, Bacon & Hanlin (E+) may influence earthworm communities in soil compared to non-toxic endophyte (NE+) infected tall fescue. Conversely, different earthworms may contribute different amounts of N to E+ vs. NE+ tall fescue. A field survey was conducted from January 2007 to January 2008 to determine the impact of E+ and NE+ tall fescue, planting date, and seasonal variables, e.g. soil temperature and moisture, on earthworm species, abundances, and population …

The Thundering Throne: Personality, Poetics, And Gender In The Court Of King Henry Viii, Rebecca Marie Moore

Graduate Theses and Dissertations

This work examines gender in the court of King Henry VIII, focusing specifically on the role that the power and weight of Henry's personal decisions played in shaping the contemporary Social definitions of femininity, masculinity, and courtiership. The space of courtiership is particularly open to such inquiry because this space was so often one that revealed the fissures and failures in attempts to maintain the strict binaries that privileged hegemonic masculinity under Henry. These definitions, then, will be reflected in, as well as shaped by, court poetry and, as explored in the final chapter, prose. Literature produced within the context …

Effect Of Soyasaponin Fractions On Human Colon Cancer Cells, Joseph Tyler Salyer

Graduate Theses and Dissertations

Group B saponins, the predominant form of saponins in heat-treated soy products, have been shown to possess hypocholesterolemic, antimutagenic, and anticarcinogenic properties. Previous studies have evaluated crude mixtures of soyasaponins, but studies evaluating a single purified soyasaponin as an anticarcinogenic agent are limited. The goal of this study is to examine the effects of purified soyasaponins I and III as well as their aglycone form, soyasapogenol B, as anticarcinogenic agents on the human colon adenocarcinoma cell line Caco-2. Experiments were conducted to determine the effects of purified soyasaponins on cell proliferation, Protein Kinase C (PKC) activity, and cell morphology in …

Defining, Executing And Visualizing Representative Workflows In A Retail Domain, May Zeineldin

Graduate Theses and Dissertations

Our lives are filled with routine activities that we do more or less on auto-pilot such as driving to work and cooking. This thesis explores a workflow representation as a way to represent such activities of daily living. The domain of a retail store environment is used. Workflows are initially expressed in a structured English representation, then translated into a Petri net notation and implemented in mix of Petri nets, Lua, and C so that the resulting workflows can be displayed as the actions of collections of avatarbots (avatars controlled by programs) in a 3D virtual world, Second Life. One …

The Role Of Atpase In The Development Of Idiopathic Pulmonary Arterial Hypertension In Broilers, Jessica Worley

Biological Sciences Undergraduate Honors Theses

The goal of this study was to assess the ATPase activity in the vascular walls of the pulmonary artery, 1A arteriole, and 2A arteriole of the lung of broilers susceptible to idiopathic pulmonary arterial hypertension. This was achieved through the modification of tryptophan in the diet and through the examination of the ATPase activity in the different pulmonary vessels. A QuantiChrom ATPase assay quantified the amount of phosphate ion correlating to the amount of ATPase activity, which was normalized for vessel size using the Coomassie and MicroBCA Protein Assays (giving ?M of phosphate/?g of protein per mL). One way repeated …

Over $10 billion losses in the poultry industry were caused by avian influenza (AI) so far. Rapid and specific detection of avian influenza virus is urgently needed with the concerns over the outbreaks of highly pathogenic H5N1 influenza virus and cases of animal and human infection. Aptamers are oligonucleic acid or peptide molecules that bind a specific target molecule with good affinity. They show better thermal stability than antibodies. The goal of this research was to select DNA-aptamers as the specific recognition element of AI H5N1virus to be used in detection assays specific for field application. In this study, Systematic …

Toward A Constructive Engagement: Agricultural Biotechnology As A Public Health Incentive In Less-Developed Countries, Chidi Oguamanam

Journal of Food Law & Policy

Discourses on global public health crises, especially as they impact the less-developed world, focus mostly on the issue of access to life-saving drugs for needy populations. Also, they implicate the misalignment of global pharmaceutical research and development (R&D) agenda with the health needs of the poor. Equally attracting significant attention is the role of intellectual property in driving up the cost of drugs and exacerbating the drug access freeze to needy populations. More often, the conceptual strings of these discussions are woven around a complex interaction of themes, including those of globalization, the development narrative, and strategic changes in international …

Legitimate Exercises Of The Police Power Or Compensable Takings: Courts May Recognize Private Property Rights, Terence J. Centner

Journal of Food Law & Policy

Under their police power, governments regulate nuisances and take actions in emergency situations. For protecting humans, animals, and plants from diseases and other pests (jointly referred to as diseases), governments order inoculations, quarantine items and people, and seize and destroy property.' With respect to plants and animals, the United States Secretary of Agriculture is authorized to prohibit the importation and movement of items than may be infested. The Secretary also has the authority to hold, treat, and destroy items to prevent the dissemination of plant and animal pests. State governments take additional actions to prevent the introduction and dissemination of …

Current And Emerging Issues In The New Urban Agriculture: A Case Study, Kathryn A. Peters

Journal of Food Law & Policy

Urban agriculture takes many forms, including individual gardens on privately owned land, neighborhood gardens, community gardens, and gardens located on church and school grounds, housing developments, and other publicly owned property. The most essential factors for successful urban agriculture efforts include land acquisition, zoning ordinances, access to affordable water, infrastructure, and support services such as education and outreach. Cities across the United States have formed task forces with the mission of making their cities more sustainable or strengthening the local food supply system; urban agriculture is instrumental in both of these missions. Major cities across the United States are recognizing …

The Tragedy Of The Horse, American Icon, Tim Opitz

Journal of Food Law & Policy

Whether a prohibition on slaughter improves the welfare of the American horse population is the focus of this article. At the time it was written, winter of 2010-2011, a confluence of Federal and State legislative action had ended domestic slaughter. These actions are detailed in the body of this article. Since 2007, the legal status of horse slaughter remained static. Just as Sir Isaac Newton's first law of motion explained, an object at rest tends to stay at rest. Legislative inertia is the perspective from which this article was originally written. However, Newton's first law also stated that the object …

United States Food Law Update: Moving Toward A More Balanced Food Regulatory Regime, A. Bryan Endres, Nicholas R. Johnson

Journal of Food Law & Policy

For decades, the federal government has played a significant role in promoting healthy eating. In the early 1900s, the United States Department of Agriculture (USDA) promoted a foundational diet of milk, proteins, fruits and vegetables, and grains. Most Americans are at least somewhat familiar, although perhaps confused, with the more nuanced healthy eating recommendations contained in the food pyramid - first employed in 1992. And virtually every American has experienced the federally supported school lunch program. In the first half of 2011, these two iconic programs underwent significant change as part of a stepped-up effort to improve the health of …
