The Function Of Carmil1 In Migrating Cells, Marc Edwards

All Theses and Dissertations (ETDs)

This dissertation describes the physiological role of the Capping Protein- CARMIL interaction in migrating cells. I establish the CARMIL-CP complex as a key regulator of lamellipodial actin assembly and of lamellipodial dynamics. Membrane ruffling at the leading edge of motile cells and macropinocytosis were also found to be dependent on the CARMIL1-CP interaction. This is consistent with macropinocytosis and ruffling being dependent on a functional and dynamic lamellipodium.: Kerr and Teasdale, 2009).

In chapter two I demonstrate that the CBR of CARMIL1 is competent to inhibit CP in cells. I show that overexpression of the CBR in cells leads to …

Understanding Crx-Associated Retinopathies Using Animal Models, Nicholas Minh Abell Tran

All Theses and Dissertations (ETDs)

Cone-rod homeobox: CRX) protein is a "paired-like" homeodomain transcription factor that is essential for regulating rod and cone photoreceptor transcription. Mutations in human CRX are associated with the dominant retinopathies Retinitis Pigmentosa: RP), Cone-Rod Dystrophy: CoRD) and Leber Congenital Amaurosis: LCA), with variable severity. The goal of my dissertation project was to develop and characterize animal models to understand genetic mechanisms of phenotypic diversity in CRX-associated disease. Heterozygous Crx Knock-Out: KO) mice: "+/-") have normal vision as adults and fail to model the dominant human disease.

Leave Prejudice Behind, Pei-Chen Chien

Theses

In this thesis, I strive to expose societal rules and regulations that constrict and restrict our social interactions in a way that promotes prejudice and xenophobia. Through interacting with the series of sculptures, viewers are given the opportunity to question these societal norms and start a process of self- reflection to truly understand the freedom that comes without prejudice. Interaction is the main element that ties the series of works together, to form a seamless journey of self-discovery. The following artists are discussed in relation to this series of work: Niki de Saint Phalle and Björk Guðmundsdóttir. Their art works …

Bugchaser: Protective Measures, Scott Laforce

Theses

Using photographic installation and new media, Bugchaser: Protective Measures examines risk in response to perceived danger as engaged by bug chasers (or bugchasers) and suburbanites in the United States. The work explores this theme through the contrasting nature of queer social networks and the physical boundaries of the suburban landscape.

Ultimately, this work uproots conventional notions of intimacy as conscribed by the suburban middle-class and de-stigmatizes unconventional behaviors by challenging boundaries that needlessly divide. I have taken liberty with metaphor and used it in an attempt to reverse some of the damages brought forth through historical practices. If the viewer …

Private Flashbulb Memories: The Case Of Coming Out Memories, Gabrielle Weber

Undergraduate Honors Thesis Collection

Participants (N = 83) from Butler University and communities in Indianapolis, IN answered a three part questionnaire regarding their experience revealing their homosexual identity to their parents that included: a narrative, a set of probe questions, and a short demographic section. The narrative and probed recall data were scored in a similar fashion to flashbulb memory narratives with canonical features. The memory of revealing homosexuality to parents displayed flashbulb-like qualities. We found that those most confident in their probed recall answers were those with moderate arousal and few recounts. Also, those reporting moderate affect and fewer recounts had better memory …

Using Lagrangian Coherent Structures To Study Coastal Water Quality, Laura A. Fiorentino

Open Access Dissertations

The accumulation of pollutants near the shoreline can result in low quality coastal water with negative effects on human health. To understand the role of mixing by tidal flows in coastal water quality, we study the nearshore Lagrangian circulation of four recreational beaches in Miami, FL, who, despite close proximity, have varying microbial levels. Specifically, we reveal Lagrangian Coherent Structures (LCSs), i.e., distinguished material curves which shape global mixing patterns and thus act as skeletons of the Lagrangian circulation. We show how these material curves, which shape circulation and mixing patterns, can be used to explain the incongruous states of …

Investigations Of Cost-Effective Biodiesel Production From High Ffa Feedstock, Lesly N. Lesmes Sanchez

Electronic Thesis and Dissertation Repository

Commercial production of biodiesel from refined vegetable oils has been widely practiced. However, more economic raw materials are required in order to make biodiesel competitive in the fuel market. This is a challenge since low-cost lipid feedstock contains high concentrations of free fatty acids (FFA) and water, which inhibit transesterification. This work investigates new catalyst combinations and method configuration to develop a cost-effective and suitable process utilizing refined canola oil and canola oil with high oleic acid content. Results suggest that potassium carbonate is more tolerant to water in the feed and enhances phase separation when compared to traditional catalyst, …

Online Information Search, Market Fundamentals And Apartment Real Estate, Prashant Das

Real Estate Dissertations

Using a system of multi-step equations, I examine the association between online rental searches and fundamental apartment real estate market variables namely, vacancy rates, rental rates and real estate asset price returns. I find that consumer real estate searches are significantly associated with the market fundamentals after controlling for known determinants of these variables. In particular, I show that apartment rentals related online searches are endogenously and contemporaneously associated with reduced vacancy rate. However, the association between the searches and rental rates is not significantly detected. The searches are contemporaneously associated with positive return on the appraised values of multifamily …

However, the film cooling effectiveness has almost reached plateau, resulting in a bottleneck for continuous improvement of gas turbines' efficiency.

In this study, an innovative cooling scheme, mist film cooling is investigated through experiments. A small amount of tiny water droplets with an average diameter about 10-15 …

A Wedge Impact Theory Used To Predict Bow Slamming Forces, Ashok Benjamin Basil Attumaly

University of New Orleans Theses and Dissertations

The pressures and impact forces acting on a hull while experiencing bow wave slamming is analyzed using Vorus' Impact Theory. The theory extends the hydrodynamic analysis of planing hulls from simple wedges to irregular shapes using a Boundary Element Method. A Fortran-based code developed by the Author is used to analyze hullforms. Linear strip theory is used to extend the analysis over a three dimensional hull. Post-processing of output data gives hull pressure distributions at different time steps and is visually presentable.

A Numerical Study Of High Temperature And High Velocity Gaseous Hydrogen Flow In A Cooling Channel Of A Ntr Core, Sajan B. Singh

University of New Orleans Theses and Dissertations

Two mathematical models (a one and a three-dimensional) were adopted to study, numerically, the thermal hydrodynamic behavior of flow inside a single cooling channel of a Nuclear Thermal Rocket (NTR) engine. The first model assumes the flow in the cooling channel to be one-dimensional, unsteady, compressible, turbulent, and subsonic. The working fluid (GH₂) is assumed to be compressible. The governing equations of the 1-D model are discretized using a second order accurate finite difference scheme. Also, a commercial CFD code is used to study the same problem. Numerical experiments, using both codes, simulated the flow and heat transfer …

Dynamic User Defined Permissions For Android Devices, Christopher D. Stelly

University of New Orleans Theses and Dissertations

Mobile computing devices have become an essential part of everyday life and are becoming the primary means for collecting and storing sensitive personal and corporate data. Android is, by far, the dominant mobile platform, which makes its permissions model responsible for securing the vast majority of this sensitive data.

The current model falls well short of actual user needs, as permission assignments are made statically at installation time. Therefore, it is impossible to implement dynamic security policies that could be applied selectively depending on context. Users are forced to unconditionally trust installed apps without means to isolate them from sensitive …

Intraurban Variability Of Ambient Particulate Matter, Varun Yadav

All Theses and Dissertations (ETDs)

An understanding of spatial and temporal variability in ambient particulate matter: PM) is important for effective air quality management and for assessing potential exposure misclassification in epidemiological and exposure studies used to support health-based standards. Spatiotemporal variability of PM in urban areas can be influenced by many factors, such as local sources of primary PM; source locations and their emission profiles; topographic barriers; meteorological patterns; behavior of semi-volatile components; and measurement errors. Intraurban variability is often gauged by conducting measurements at a network of monitoring stations across the region of interest. While certain statistical metrics are commonly used and interpreted …

A Multi-Gene By Environment Perspective Of Adhd Symptomatology In Young Children, Amber L. Allison

University of New Orleans Theses and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a heritable disorder, which has detrimental effects on childhood development and is associated with maladaptive functioning in adulthood. Despite this, we are far from an understanding of the etiology and possible trajectories of ADHD, possibly due to investigations focusing on the contribution of single genes. In fact, single genes are likely not influential enough to alter behavior, but the additive effect of many genes may predispose an individual toward certain behaviors. Further, environmental input can activate or suppress genetic expression, thereby leading to vast individual differences in both normative behavior and psychopathological illness, including …
