Effects Of Cellular Heterogeneity And Immune Cells In Angiotensin Ii-Infused Hemorrhaged Ascending Aortas, Kyung Sik Jung

Theses and Dissertations--Toxicology and Cancer Biology

A previous thoracic aortic aneurysm time course study from our laboratory determined that ascending aortic dilation was significantly increased by day 5, and reached a plateau by day 28 of angiotensin II (AngII) infusion. We also found that mice had hemorrhage localized to the ascending aortas by day 5 of AngII infusion. The purpose of these studies was to provide mechanistic insight into the development of AngII-induced ascending aortic hemorrhage.

Male C57BL/6 mice fed normal diet were subcutaneously infused with either AngII (1000 ng/kg/min) or saline for 5 days. To examine cellular heterogeneity, hemorrhaged ascending aortas were collected and sectioned …

Locative Media, Augmented Realities And The Ordinary American Landscape, Andrew Boulton

Theses and Dissertations--Geography

This dissertation investigates the role of annotative locative media in mediating experiences of place. The overarching impetus motivating this research is the need to bring to bear the theoretical and substantive concerns of cultural landscape studies on the development of a methodological framework for interrogating the ways in which annotative locative media reconfigure experiences of urban landscapes. I take as my empirical cases i) Google Maps with its associated Street View and locational placemark interface, and ii) Layar, an augmented reality platform combining digital mapping and real-time locational augmentation. In the spirit of landscape studies’ longstanding and renewed interest in …

Re-Placing Sprawl: Mapping Place In An American Suburb, Ryan M. Cooper

Theses and Dissertations--Geography

In the post-World War II era land development in the United States has largely been focused on the expansion away from urban centers and out into the surrounding suburbs. While the development of suburbs began with utopian ideals of spiritual wholeness, their actual manifestation on the American landscape has been subject to harsh critiques about their long-term economic and environmental feasibility, fostering of social alienation, and general placelessness. In this thesis I address the criticism of suburbs as placeless, asking ―What are the particular practices of place-making in North American suburbs?‖ Examining interviews, cognitive map surveys, participant observation, archival materials, …

Neoliberalizing The Streets Of Urban India: Engagements Of A Free Market Think Tank In The Politics Of Street Hawking, Priyanka Jain

Theses and Dissertations--Geography

This dissertation looks into the processes by which neoliberalism is mutating with various local and global discourses in order to transform urban space for marginalized street hawkers in the Global South, specifically Delhi, India. Following the current engagements in geographic literature on neoliberalism that focus on the contextually embedded character and the path-dependent process of the spread of free market ideas, I make free market advocacy think tanks--a rather unknown and under-investigated accomplice to this process--my main entry point. Corporate funded think tanks are often found advocating a neoliberal doctrine of free markets, minimal government intervention, and privatization. A self-professed …

Evaluation Of Chemical Additives For The Separation And Recovery Of Bacteria From Food Matrices, Jennifer Leanne Frederick, Stephen P. Walker, Czarena L. Crofcheck, Melissa Newman, Frederick Payne

Biosystems and Agricultural Engineering Faculty Publications

The microbiological testing of foods is a well-established science. Due to the severity of foodborne pathogen illnesses, the widespread use and implementation of rapid detection methods in food testing labs is increasingly important. The first step for successful testing is sampling. Surfactants have been widely used in food microbiology, but there is not much, if any, published research about the use of fatty alcohols and chemical dispersants as aids in microbial separation and recovery. The microbial extraction efficiency of Escherichia coli K12 and Listeria innocua from three representative food matrices (hot dogs, spinach, and milk) was measured using chemical additives …

The Impact Of Discontinuing Coverage Of Second Generation Antihistamines In A Managed Care Organization, Matthew D. Harman

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

ABSTRACT Background: Second generation antihistamines (SGAs) are approved to treat seasonal and/or perennial allergic rhinitis (AR) and chronic idiopathic urticaria (CIU). It is estimated that 82% of Americans with AR use antihistamines, with the majority using SGAs due to their low side effect profile. As policy, over-the-counter (OTC) SGAs were not covered in this health plan population (cetirizine and loratadine products were available OTC prior to the study period, while fexofenadine products became available OTC during the study period). On January 1, 2012, the policy was extended to remove coverage of prescription-only SGAs (included desloratadine and levocetirizine products). Objectives: To …

Impact Of Direct-Fed Microbials On Nutrient Utilization In Beef Cattle, Nicole Kenney

Theses and Dissertations--Animal and Food Sciences

The impact of lactate producing direct-fed microbial (DFM) on growth performance and rumen fermentation in beef cattle was explored in four studies. Experiment 1 studied the interaction between DFM and degradable intake protein (DIP) supply in receiving cattle. No differences (P≥0.06) in intake, morbidity, or immune response were observed; however, during the first 28 d gain and efficiency responses to DFM were dependent on DIP (DIP×DFM P≤0.05). Experiment 2 showed that in vitro gas production and select endpoint metabolites differed (P≤0.04) with DFM application. Experiment 3 compared lactate producing DFM to a lactate producing/utilizing DFM in finishing cattle. No differences …

Detection Of Antibodies Against Parascaris Equorum Excretory-Secretory Antigens, Steffanie V. Burk

Theses and Dissertations--Animal and Food Sciences

Parascaris equorum is a nematode parasite that infects young horses, sometimes causing unthriftiness, respiratory signs, or intestinal impaction in severe cases. Infection can be diagnosed by detection of eggs in feces, but this is only possible after the worms are fully mature. The goal of this study was to develop an antibody-based test for prepatent diagnosis of P. equorum infection. To produce western blot (WB) antigen, P. equorum larvae were cultured for collection of excretory-secretory antigens (ESA). Sera from 18 pregnant broodmares, their subsequent foals, and a group of 12 older mares and geldings were analyzed. In order to check …

Analysis Of Antiviral And Chemoprotective Effects Of Strawberry Anthocyanins, Jennifer A. Willig

Theses and Dissertations--Animal and Food Sciences

This study investigated the antiviral, chemoprotective and proliferative effects of strawberry anthocyanins on herpes simplex virus type-1, cancerous cell lines HT-29 and AGS, and normal cell lines Hs 738.St/Int and CCD-18Co. Antiviral properties were measured by infecting vero cells from adult grivet (Cercopithecus aethiops) with herpes simplex virus type-1 (HSV-1) and treating with a concentration of 1.25-20 µg/mL of strawberry anthocyanins. Infectivity and replication were quantified for herpes simplex virus type-1 using the direct plaque assay and reporting PFU/mL. Strawberry anthocyanins (>20 µg/mL) inhibited the herpes simplex virus infectivity in vero cells by 100% (p<0.05). Strawberry anthocyanins at concentrations of 5, 10 and 20 μg/mL were reduced to 75.36, 57.98, and 31.46 percent of the control (100%) (p<0.05).

Witnessing The Web: The Rhetoric Of American E-Vangelism And Persuasion Online, Amber M. Stamper

Theses and Dissertations--English

From the distribution of religious tracts at Ellis Island and Billy Sunday’s radio messages to televised recordings of the Billy Graham Crusade and Pat Robertson’s 700 Club, American evangelicals have long made a practice of utilizing mass media to spread the Gospel. Most recently, these Christian evangelists have gone online. As a contribution to scholarship in religious rhetoric and media studies, this dissertation offers evangelistic websites as a case study into the ways persuasion is carried out on the Internet. Through an analysis of digital texts—including several evangelical home pages, a chat room, discussion forums, and a virtual church—I investigate …

The Everyday Spaces Of Humanitarian Migrants In Denmark, Malene H. Jacobsen

Theses and Dissertations--Geography

Furthermore, it examines how humanitarian migrants experience their everyday life in the Danish asylum system. An examination of state practices in conjunction with humanitarian migrants’ narratives of space and everyday practices, offers an opportunity to explore what kind of politics and political subjectivities that can emerge in the space of humanitarian migrants. This research contribute to our understanding of first, how the securitization of migration has direct impact …

Audience Response To The Nature/Society Binary In Kurosawa’S Dersu Uzala: An Observational Online Ethnography, Laura L. Sharp

Theses and Dissertations--Geography

Geographers researching cinema have predominantly been interested in how geographic meaning is constructed and negotiated within film, but have been less productive in accounting for how these constructs are received by viewers. Using the method of observational online ethnography, I therefore investigate how fans in online reviews have interpreted the nature/society binary in the film Dersu Uzala. Working from a social constructionist view of nature I begin by deconstructing the binary as it appears in Dersu Uzala before proceeding to illustrate the way this constitutive absence is made up for by the visuality of the film’s landscapes and techniques of …

Moveable Feasts: Locating Food Trucks In The Cultural Economy, Jessa M. Loomis

Theses and Dissertations--Geography

In this thesis, I consider the emergence of a new generation of food trucks and question their popularity, narration and representation. I examine the economic and cultural discourses that have valorized these food trucks, and pay attention to the everyday material and embodied practices that constitute them. This research is situated in Chicago, where proposed changes to the existing mobile food vending ordinance spurred contentious debates about food safety, regulations, rights to the city and livelihoods. I follow the myriad actors involved in the food truck movement to understand the strategies employed to change the mobile food vending ordinance on …

Biological Control Of Manganese In Water Supplies In The Presence Of Humic Acids, Michael S. Snyder

Theses and Dissertations--Civil Engineering

The main objective of this study was to improve our understanding of biological filtration (biofilm type) treatment for manganese (Mn) removal in drinking water. Biological filtration treatment involves biofilms of Mn(II)-oxidizing microorganisms attached to solid filter material that remove and immobilize dissolved Mn(II) in raw water by conversion to black MnO_2(s) precipitates. Mn-biological filtration is an emerging green technology that can serve as an alternative to conventional physicochemical treatments but its full potential is hindered by various factors. These include lack of understanding the: (1) optimal removal conditions for Mn, (2) mechanisms for Mn releases of the accumulated Mn …

Noninvasive Near-Infrared Diffuse Optical Monitoring Of Cerebral Hemodynamics And Autoregulation, Ran Cheng

Theses and Dissertations--Biomedical Engineering

Many cerebral diseases are associated with abnormal cerebral hemodynamics and impaired cerebral autoregulation (CA). CA is a mechanism to maintain cerebral blood flow (CBF) stable when mean arterial pressure (MAP) fluctuates. Evaluating these abnormalities requires direct measurements of cerebral hemodynamics and MAP. Several near-infrared diffuse optical instruments have been developed in our laboratory for hemodynamic measurements including near-infrared spectroscopy (NIRS), diffuse correlation spectroscopy (DCS), hybrid NIRS/DCS, and dual-wavelength DCS flow-oximeter. We utilized these noninvasive technologies to quantify CBF and cerebral oxygenation in different populations under different physiological conditions/manipulations. A commercial finger plethysmograph was used to continuously monitor MAP. For investigating …

Unsaturated Soil Parameters From Field Stiffness Measurements, Jason M. Curd

Theses and Dissertations--Civil Engineering

The behavior of unsaturated soils depends heavily on material properties and soil conditions. In Geotechnical Engineering, compacted soils are frequently used as fill material, and quality control is vital to the construction process. There are few methods available to estimate the parameters associated with unsaturated soils based on field measurements, and a relationship between these factors could reduce testing time and lower construction costs. Undrained triaxial tests were performed on four clays representing a range of material properties in an effort to reach the maximum dry density, which provides the highest bearing capacity. Each clay was compacted at optimum moisture …

Water Quality Sensor Placement Guidance For Small Water Distribution Systems, Stacey L. Schal

Theses and Dissertations--Civil Engineering

Water distribution systems are vulnerable to intentional, along with accidental, contamination of the water supply. Contamination warning systems (CWS) are strategies to lessen the effects of contamination by delivering early indication of an event. Online quality monitoring, a network of sensors that can assess water quality and alert an operator of contamination, is a critical component of CWS, but utilities are faced with the decision of what locations are optimal for deployment of sensors. A sensor placement algorithm was developed and implemented in a commercial network distribution model (i.e. KYPIPE) to aid small utilities in sensor placement. The developed sensor …

A Three-Dimensional Quantitative Understanding Of Short Fatigue Crack Growth In High Strength Aluminum Alloys, Wei Wen

Theses and Dissertations--Chemical and Materials Engineering

The behaviors of short fatigue crack (SFC) propagation through grain boundaries (GBs) were monitored during high cycle fatigue in an Al-Li alloy AA8090. The growth behaviors of SFCs were found to be mainly controlled by the twist components (α) of crack plane deflection across each of up to first 20 GBs along the crack path. The crack plane twist at the GB can result in a resistance against SFC growth; therefore SFC propagation preferred to follow a path with minimum α at each GB. In addition to the grain orientation, the tilting of GB could also affect α.

An experiment …

Visual Semantic Segmentation And Its Applications, Jizhou Gao

Theses and Dissertations--Computer Science

This dissertation addresses the difficulties of semantic segmentation when dealing with an extensive collection of images and 3D point clouds. Due to the ubiquity of digital cameras that help capture the world around us, as well as the advanced scanning techniques that are able to record 3D replicas of real cities, the sheer amount of visual data available presents many opportunities for both academic research and industrial applications. But the mere quantity of data also poses a tremendous challenge. In particular, the problem of distilling useful information from such a large repository of visual data has attracted ongoing interests in …

The United States And The Congo, 1960-1965: Containment, Minerals And Strategic Location, Erik M. Davis

Theses and Dissertations--History

The Congo Crisis of the early 1960s served as a satellite conflict between the United States and the Soviet Union during the Cold War. Scholars have argued about U.S. motivations and interests involved in the Congo Crisis. The major division between scholars is between those who contend the United States acted for national security reasons and those scholars who argue the United States desired to establish a neocolonial regime to protect economic interests pertaining to vast Congolese mineral wealth. The argument of this thesis is that the United States policy in the Congo between 1960 and 1965 focused on installing …

Instruments Of Righteousness: The Intersections Of Black Power And Anti-Vietnam War Activism In The United States, 1964-1972, Amanda L. Higgins

Theses and Dissertations--History

Instruments of Righteousness investigates the class-, race-, and gender-based identities and intersections of women and men in the Black Power movement and their various organizing activities to gain certain and defined concessions from federal, state, and local governments. It argues that the intersections of Black Power and anti-Vietnam War activism created changing definitions of black masculinity and femininity, expressed through anti-draft and anti-war work. Black Power and anti-war activism cannot and should not be investigated separate from one another. The experiences of Black Power soldiers, antiwar members of the Student Nonviolent Coordinating Committee (SNCC), the Black Panther Party, and the …
