Exploration Of Non-Chemically Amplified Resists Based On Dissolution Inhibitors For 193 Nm Lithography, Burak Baylav

Theses

Research described in this work includes exploration of new resist systems that can be used for 193 nm lithography. Most of the conventional 193 nm resists rely on chemical amplification in which a small amount of photogenerated acid can catalyze many reactions. Even though the sensitivity is improved drastically with such a mechanism, the printed profiles are known to be suffering from line edge roughness (LER) and image blurring. Furthermore, the resolution is limited by the diffusion length of the generated acid. For sub-32 nm technology nodes, specified LER criterion cannot be satisfied by utilizing chemically amplified resists (CAR). However, …

The Bachelor Narrator Motif In The Sketches Of Nathaniel Hawthorne, Carol L. Anderson

Theses, Dissertations and Culminating Projects

This thesis examines the bachelor narrator motif in seven of Nathaniel Hawthorne’s sketches, published between 1831 and 1843. Hawthorne’s narrators are artists, alienated from society in general, and from women in particular. Moreover, they are modeled upon the figure of the European flaneur, the idle ‘man about town’ who believes he can read the character of the stranger in the crowd. In these first person narrations, Hawthorne explores the problems of subjectivity (involving self-concept, including the split between the conscious and the unconscious, and the gap between the mind and the material world) and the problem of knowledge (involving the …

Multi-walled carbon nanotubes (MWNTs) are a relatively new allotrope of carbon that have potentially useful properties that may improve polymer composites. The work of this thesis explores the interactions between MWNTs and functionalized MWNTs within epoxy matrix and the properties of the MWNT/epoxy composite. These interactions were characterized with an emphasis on finding how well the MWNT/epoxy composite flows and how conductive it is after curing.

A Continuous Mathematical Model Of The One-Dimensional Sedimentation Process Of Flocculated Sediment Particles, Sebastian Fernando Torrealba

University of Kentucky Doctoral Dissertations

A new continuous one-dimensional sedimentation model incorporating a new continuous flocculation model that considers aggregation and fragmentation processes was derived and tested. Additionally, a new procedure to model sediment particle size distribution (PSD) was derived. Basic to this development were three different parametric models: Jaky, Fredlund and the Gamma probability distribution (GPD) were chosen to fit three different glass micro-spheres PSDs having average particle sizes of 7, 25 and 35 microns. The GPD provided the best fit with the least parameters. The bimodal GPD was used to fit ten sediment samples with excellent results (< 5% average error). A continuous flocculation model was derived using the method of moments for solving the continuous Smoluchowski coagulation equation with fragmentation. The initial sediment PSD was modeled using a bimodal GPD. This new flocculation model resulted in a new general moments’ equation that considers aggregation and fragmentation processes, which is represented by a system of ordinary differential equations. The model was calibrated using a genetic algorithm with initial and flocculated PSDs of four sediment samples and four anionic polyacrylamides flocculants. The results show excellent correlation between predicted and observed values (R² > 0.9878). A new continuous …

Audio Scene Segementation Using A Microphone Array And Auditory Features, Harikrishnan Unnikrishnan

University of Kentucky Master's Theses

Auditory stream denotes the abstract effect a source creates in the mind of the listener. An auditory scene consists of many streams, which the listener uses to analyze and understand the environment. Computer analyses that attempt to mimic human analysis of a scene must first perform Audio Scene Segmentation (ASS). ASS find applications in surveillance, automatic speech recognition and human computer interfaces. Microphone arrays can be employed for extracting streams corresponding to spatially separated sources. However, when a source moves to a new location during a period of silence, such a system loses track of the source. This results in …

Control Force Estimation In Seismic Building Design, Xiaozhe Zhang, Franklin Y. Cheng

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This paper presents two approaches of estimating the control force magnitude in the building structure's seismic design. One is by spectrum average in frequency domain, and the other is by nondeterministic Monte Carlo analysis in time domain. the spectrum method is proposed to find the estimation by averaging the system's frequency response with an earthquake spectrum as a weighting factor. the nondeterministic method is based on sets of potential ground motions generated numerically. the approaches are developed in the concept of performance design, with studies based on the site potential seismic hazard and presenting results at different levels of displacement …

Wireless Sensor Network Radio Power Management And Simulation Models, Michael I. Brownfield, Theresa Nelson, Scott Midkiff, Nathaniel J. Davis Iv

Faculty Publications

Wireless sensor networks (WSNs) create a new frontier in collecting and processing data from remote locations. The IEEE 802.15.4 wireless personal area network-low rate (WPAN-LR) WSNs rely on hardware simplicity to make sensor field deployments both affordable and long-lasting without maintenance support. WSN designers strive to extend network lifetimes while meeting application-specific throughput and latency requirements. Effective power management places sensor nodes (or motes) into one of the available energy-saving modes based upon the sleep period duration and the current state of the radio. The newest generation of WPAN-LR-based sensor platform radios operates at a 250 kbps data rate and …

Turbulent Mixing In A Strongly Forced Salt Wedge Estuary, David K. Ralston, W. Rockwell Geyer, James A. Lerczak, Malcolm Scully

OES Faculty Publications

Turbulent mixing of salt is examined in a shallow salt wedge estuary with strong fluvial and tidal forcing. A numerical model of the Merrimack River estuary is used to quantify turbulent stress, shear production, and buoyancy flux. Little mixing occurs during flood tides despite strong velocities because bottom boundary layer turbulence is dislocated from stratification elevated in the water column. During ebbs, bottom salinity fronts form at a series of bathymetric transitions. At the fronts, near-bottom velocity and shear stress are low, but shear, stress, and buoyancy flux are elevated at the pycnocline. Internal shear layers provide the dominant source …

Bundling Public And Private Goods: The Market For Sustainable Organics, Margot J. Pollans

Elisabeth Haub School of Law Faculty Publications

Modern agriculture has vast environmental externalities. The pesticides, fertilizers, and sediments in irrigation runoff pollute surface and groundwater; single-crop farms destroy biodiversity; and massive amounts of fossil fuels are burned in agricultural production, post-harvest processing, and shipping. Nevertheless, farming operations have largely escaped the post-1970 expansion of federal environmental regulation. Compounding the problem, federal farm policy has encouraged the very farming practices that most cause this degradation.

In 1990, Congress passed the Organic Foods Production Act (OFPA), which created an organic food certification and labeling system. While OFPA's primary purposes are to facilitate the growth of the organic sector and …

Siting Green Infrastructure: Legal And Policy Solutions To Alleviate Urban Poverty And Promote Healthy Communities, Alexandra Dapolito Dunn

Elisabeth Haub School of Law Faculty Publications

Green infrastructure is an economically and environmentally viable approach for water management and natural resource protection in urban areas. This Article argues that green infrastructure has additional and exceptional benefits for the urban poor which are not frequently highlighted or discussed. When green infrastructure is concentrated in distressed neighborhoods—where it frequently is not—it can improve urban water quality, reduce urban air pollution, improve public health, enhance urban aesthetics and safety, generate green collar jobs, and facilitate urban food security. To make these quality of life and health benefits available to the urban poor, it is essential that urban leaders remove …

Together, these nations account for nearly 50 percent of the world’s population. The article discusses environmental justice issues associated with contaminated drinking water and insufficient sanitation and explores the role that public versus private ownership of water infrastructure plays in ensuring access to clean water for the lower-income echelons of society. It articulates the importance of the rule of law and sound environmental governance in this arena and …

Practically Grounded: Convergence Of Land Use Law Pedagogy And Best Practices, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

The changing dynamics in the field of land use and sustainable community development law demand that land use law professors rethink the way in which we prepare law students to practice law in this area. This needed paradigm shift converges with the growing momentum of the best practices movement which urges law schools to dramatically revise the curricular approach to legal education, arguing that traditional models are no longer effectively serving the goal of producing competent and fully prepared new lawyers. A perfect storm is present and a unique opportunity exists through the application of many “best practices” concepts for …

We Can Work It Out: Co-Op Compulsory Licensing As The Way Forward In Improving Access To Anti-Retroviral Drugs, Horace E. Anderson

Elisabeth Haub School of Law Faculty Publications

This Article explores the social and developmental underpinnings of the access problem and describes the legal framework that provides the backdrop for the Waiver's licensing scheme. Part III examines the various lenses, humanitarian, economic, and political, through which the underutilization problem may be viewed and explained. Part IV sets out the structural heart of the Waiver scheme's deficiencies: the notion of the “compulsory” license itself. Part V posits a co-op scheme of licensing that aligns the concerns, goals, and incentives of IP owners, importers, exporters, and consumers. Finally, the Article relates the proposed scheme to more general trends in thinking …

Emerging Law Addressing Climate Change And Water, Elizabeth Burleson

Elisabeth Haub School of Law Faculty Publications

The World Economic Forum recognizes that while restrictions on energy affect water systems and vise versa, energy and water policy are rarely coordinated. The International Panel on Climate Change predicts that wet places will become wetter and dry places will become dryer. Transboundary water, energy and climate coordination can occur through international consensus building.

Amino Acid Transport In Thermophiles: Characterization Of An Arginine-Binding Protein In Thermotoga Maritima, Matthew S. Luchansky, Bryan S. Der, Sabato D'Auria, Gabriella Pocsfalvi, Luisa Iozzion, Daniela Marasco, Jonathan D. Dattelbaum

Chemistry Faculty Publications

Members of the periplasmic binding protein superfamily are involved in the selective passage of ligands through bacterial cell membranes. The hyperthermophilic eubacterium Thermotoga maritima was found to encode a highly stable and specific periplasmic arginine-binding protein (TM0593). Following signal sequence removal and overexpression in Escherichia coli, TM0593 was purified by thermoprecipitation and affinity chromatography. The ultra-stable protein with a monomeric molecular weight of 27.7 kDa was found to exist as both a homodimer and homotrimer at appreciable concentrations even under strongly denaturing conditions, with an estimated transition temperature of 116 °C. Its multimeric structure may provide further evidence of …

Amino Acid Transport In Thermophiles: Characterization Of An Arginine-Binding Protein In Thermotoga Maritima. 2. Molecular Organization And Structural Stability, Andrea Scirè, Anna Marabotti, Maria Staiano, Luisa Iozzion, Matthew S. Luchansky, Bryan S. Der, Jonathan D. Dattelbaum, Fabio Tanfani, Sabato D'Auria

Chemistry Faculty Publications

ABC transport systems provide selective passage of metabolites across cell membranes and typically require the presence of a soluble binding protein with high specificity to a specific ligand. In addition to their primary role in nutrient gathering, the binding proteins associated with bacterial transport systems have been studied for their potential to serve as design scaffolds for the development of fluorescent protein biosensors. In this work, we used Fourier transform infrared spectroscopy and molecular dynamics simulations to investigate the physicochemical properties of a hyperthermophilic binding protein from Thermotoga maritima. We demonstrated preferential binding for the polar amino acid arginine …

Tuning Σ-Holes: Charge Redistribution In The Heavy (Group 14) Analogues Of Simple And Mixed Halomethanes Can Impose Strong Propensities For Halogen Bonding, Kelling J. Donald, Bernard K. Wittmaack, Chad Crigger

Chemistry Faculty Publications

Halogen bonding between halide sites (in substituted organic molecules or inorganic halides) and Lewis bases is a rapidly progressing area of exploration. Investigations of this phenomenon have improved our understanding of weak intermolecular interactions and suggested new possibilities in supramolecular chemistry and crystal engineering. The capacity for halogen bonding is investigated at the MP2(full) level of theory for 100 compounds, including all 80 MH₄-_nX_n systems (M = C, Si, Ge, Sn, and Pb; X = F, Cl, Br, and I). The charge redistribution in these molecules and the (in)stability of the σ-hole at X as …

The Third Tear In Everyday Aesthetics, Katya Mandoki

Contemporary Aesthetics (Journal Archive)

Although totally overlooked by mainstream aesthetic theory, various paths were nevertheless left open for addressing everyday aesthetics, a natural yet surprisingly controversial topic. Why they were never taken until recently, when the theme of everyday aesthetics is now becoming fashionable, can be explained not only by the obvious fact of philosophical aesthetics’ restrictive focal point on art but, among other reasons, by a kind of fetishism that demands an object of recognized value for legitimating an aesthetic inquiry. This new popularity entails, however, certain theoretical risks such as clinging to traditional art-centric and beauty-centric categories to explain the everyday and …
