Instrumented Nanoindentation Studies Of Deformation In Shape Memory Alloys, Sudhir Rajagopalan

Electronic Theses and Dissertations

Near equi-atomic nickel titanium (NiTi) shape memory alloys (SMAs) are a class of materials characterized by their unique deformation behavior. In these alloys, deformation mechanisms such as mechanical twinning and stress induced phase transformation between a high symmetry phase (austenite) and a low symmetry phase (martensite) additionally occur and influence mechanical behavior and thus their functionality. Consequently, applications of SMAs usually call for precise phase transformation temperatures, which depend on the thermomechanical history and the composition of the alloy. Instrumented indentation, inherently a mechanical characterization technique for small sampling volumes, offers a cost effective means of empirically testing SMAs in …

Contributions To Automatic Particle Identification In Electron Micrographs: Algorithms, Implementation, And Applications, Vivek Singh

Electronic Theses and Dissertations

Three dimensional reconstruction of large macromolecules like viruses at resolutions below 8 Ã… - 10 Ã… requires a large set of projection images and the particle identification step becomes a bottleneck. Several automatic and semi-automatic particle detection algorithms have been developed along the years. We present a general technique designed to automatically identify the projection images of particles. The method utilizes Markov random field modelling of the projected images and involves a preprocessing of electron micrographs followed by image segmentation and post processing for boxing of the particle projections. Due to the typically extensive computational requirements for extracting hundreds of …

The study of vibration behavior of CNTs is important because of their potential engineering applications such as nano-mechanical resonators and tips of scanning probe instruments where they are subjected to mechanical vibrations. Continuum modeling is based on an elastic beam model. The interlayer van der Waals interactions are represented by Lennard-Jones potential. In finite element …

Step-Pool Morphology Of A Wilderness Headwater Stream Of The Buffalo River, Arkansas, Aaron M. Nickolotsky

Graduate Theses/Dissertations

Step-pool and cascade morphology reflect the geological and climatic factors affecting channels in mountain watersheds. This study uses longitudinal and cross-section surveys of a headwater stream in the Boston Mountains of the Ozarks Plateau region in northwest Arkansas to describe channel form and develop quantitative models for comparisons with other regions. The Bowers Hollow Creek watershed (3.5 km2) is located within the boundaries of the Forest Service’s Upper Buffalo Wilderness Area. Step-pool morphology varies with the influence of lithology and sediment supply in the Boston Mountains. However, step height and wavelength relationships are generally similar to other regions. Distribution of …

Geospatial Analysis Of Gravel Bar Deposition And Channel Migration Within The Ozark National Scenic Riverways, Missouri (1955-2003), Derek J. Martin

Graduate Theses/Dissertations

Historical land clearing is believed to be responsible for present-day channel instability in main stem reaches in the Ozark National Scenic Riverways (ONSR) in south-central Missouri. The nature of instability is related to the delivery of excess amounts of gravel sediment to stream channels and higher rates of lateral bank erosion. These conditions are of concern to resource managers because of the potential damaging effects on recreational facilities and aquatic habitat. The purpose of this study is to develop a geographic information systems (GIS)/remote sensing (RS) based methodology to monitor spatial patterns of gravel deposition and lateral channel migration within …

Use Of Force After 9/11, Stephen G. Rademaker

Chicago Journal of International Law

The events of September 11, 2001, revealed to America and the world a new threat, qualitatively different than the dangers that have faced us in the past. This new threat has required us to adopt new policies to confront it. President Bush eloquently described the threat and the Administration's policy response in an address delivered at the National Defense University on February 11 of this year. He stated: In the Cold War, Americans lived under the threat of weapons of mass destruction but believed that deterrents made those weapons a last resort. What has changed in the 21st century is …

Level And Source Of Supplemental Selenium For Beef Steers, Scott Fry, Elizabeth B. Kegley, M. Ellen Davis, Michael D. Ratcliff, Douglas L. Galloway, Ron A. Dvorak

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Selenium (Se) is deficient in many Arkansas soils; therefore, an experiment was conducted on steers to evaluate the effects of two supplemental Se sources on performance, blood metabolites, and immune function. Thirty Angus-crossbred steers were blocked by weight and assigned within block to one of 15 pens (two steers/pen). Pens were assigned randomly within blocks to one of three dietary treatments consisting of a corn-soybean meal supplement devoid of supplemental Se (negative control, NC) or corn-soybean meal supplements providing 1.7 mg supplemental Se/d as sodium selenite (inorganic Se, ISe) or as Se yeast (organic Se, OSe). Steers were offered fescue …

Incorporating Glass Transition Concepts To Explain Rice Milling-Quality Reductions During The Drying Process, Derek A. Schluterman, Terry J. Siebenmorgen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Previous research has indicated that while drying rough rice using air temperatures above the glass transition temperature (Tg), head rice yield (HRY) reductions are incurred if a state transition occurs when severe intra-kernel moisture content (MC) gradients are present. State transitions can occur by extended drying using high-temperature air or by cooling kernels below Tg before sufficient tempering has occurred. The objectives of this experiment were to determine the maximum MC removal per initial drying pass and the associated tempering durations required to prevent HRY reduction. Two long-grain cultivars, ‘Francis’ and ‘Wells’, at two harvest moisture contents (HMC) were used. …

Methods For Correcting Topographically Induced Radiometric Distortion On Landsat Thematic Mapper Images For Land Cover Classification, David Michael Rosen

Geography Masters Research Papers

Satellite imagery is commonly used to study land-use, land-cover change in mountainous areas. Classification of land-cover types is particularly difficult in this type of terrain because topography affects the spectral response of surface features. Several techniques have been developed to help compensate for this topographic effect and to increase classification accuracy.

The purpose of this study is to compare topographic correction methods to determine which produces the most accurate results. Method 1 does not use any topographic correction, serving as a control. Method 2 is based on the Lambertian model, and uses topographical data as variables in an equation. Method …

Citizen And Citizenship Within And Beyond The Nation, Tayyab Mahmud

Cleveland State Law Review

The Latina/o Critical Legal Theory (LatCrit) movement, whose point of departure was the ground furnished by Legal Realism, Critical Legal Studies, Feminist Legal Theory, and Critical Race theory, has over time incorporated teachings of Queer Theory, Postcolonial Studies, Culture Studies, and Subaltern Studies. The three contributions to this cluster in the Symposium are worthy exemplars of this legacy as they open new avenues to broaden and deepen the project of critical legal scholarship. Jointly, the three interventions constitute a formidable spatial and temporal canvas. One explores the past, one interrogates the present, and one contemplates the future. One has the …

Molecular Dynamics Simulations Of Biological Membranes In The Presence Of Cryoprotectants, Dinesh Pinisetty

LSU Master's Theses

Cryopreservation is a process that is characterized by the transport of water and cryoprotectants through the cell membrane. This phenomenon has been studied in extensive detail at the macroscopic (µm) scale but in a somewhat more limited fashion at the microscopic (nm) scale. In this study we develop several lipid bilayer models to approximate a cell membrane (nm) and present the effect of several different cryoprotectants on the structural characteristics of these lipid bilayers using molecular dynamic simulations. The lipid bilayer models included dipalmitoylphosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC) and palmitoyleylphosphatidylcholine (POPC) while the cryoprotectants included methanol and dimethylsulfoxide (DMSO). The molecular …

"Sacred Duties": How Historical Constructs Of Gender And Work Inform Women's Involvement In U.S. Higher Education, Amber Leigh Vlasnik

LSU Master's Theses

This thesis explores how arguments about gender and labor roles have determined women's exclusion from or acceptance to the academy throughout the history of the United States. Race, gender, and class are identified as interlocking identities that shape experiences and women's gendered relationship to labor is demonstrated through the use of a materialist feminist framework. By tracing the distinct eras of colonial and United States history, the thesis illustrates the debates and public mindset of each time period and how they relate to women and higher education. The thesis concludes that popular social conceptions of the female body and women's …

Within the field of neuroethics, leading scientists, ethicists, and humanists are exploring the implications of efforts to image, study, treat, and enhance the human brain.

This article focuses on one aspect of neuroethics: the confidentiality and privacy implications of advances in functional magnetic resonance imaging (“fMRI”). Following a brief orientation to fMRI and an overview of some of its current and proposed uses, this article highlights key confidentiality and privacy issues raised by fMRI in the contexts …

Hospital Chaplaincy Under The Hipaa Privacy Rule: Health Care Or "Just Visiting The Sick?", Stacey A. Tovino

Scholarly Works

Approximately seventy-nine percent of Americans believe that praying can help people recover from illness, injury or disease, and nearly seventy-seven percent of American patients would like spiritual issues discussed as part of their care. Despite Americans' strong beliefs in the health-related benefits of religious and spiritual practices and traditions, the preamble to the federal Department of Health and Human Services' ("HHS") health information privacy rule (the "Privacy Rule") explains that health care "does not include methods of healing that are solely spiritual" (the "preamble"). The preamble concludes that, "clergy or other religious practitioners that provide solely religious healing services are …

Book Review: "The Birth Of Surrogacy In Israel", Stacey A. Tovino

Scholarly Works

Instead of analyzing Israel’s Surrogate Motherhood Agreements Act from a purely legal or theoretical perspective, D. Kelly Weisberg weaves individuals, events, and other factors into a fascinating story about the Israeli legislative process. A case in point: Weisberg begins by exploring the private lives of Rachel and Benjamin, the biological parents of twin babies carried by Sarah, the first surrogate moth to carry a baby under Israel’s surrogacy law. Weisberg also explores the story of Naomi and Dan, the biological parents of a baby boy carried by Hanna, the second surrogate mother to carry a baby under the legislation. Readers …

The Life And Work Of Nick Fofonoff, T. J. Mcdougall, R. W. Schmitt, G. Veronis, F. Webster

Journal of Marine Research

Nicholas Paul Fofonoff was born August 18, 1929, and raised on a small farm near Queenstown in Alberta, Canada. His parents spoke only Russian at home, so Nick did not learn English until he attended the two-room school that served the first six grades for the town of 200. He was the second born of four, the prince among three sisters. The small school meant he was exposed to several grades at a time and could advance quickly. He also learned many practical skills on the farm from a clever father and the necessity to be self-sufficient. It was a …

The Material Derivative Of Neutral Density, Trevor J. Mcdougall, David R. Jackett

Journal of Marine Research

An expression for the rate of change of neutral density following a fluid parcel (the material derivative) is derived and checked numerically. This expression can be used to quantify the degree to which neutral density varies even under purely adiabatic and isohaline motions. We also present an approximate form of neutral density, namely a rational function of only two variables, either salinity and conservative temperature or salinity and potential temperature.

Diffusively-Driven Overturning Of A Stable Density Gradient, Andrew F. Thompson, George Veronis

Journal of Marine Research

We present the results of an experimental study on the formation and propagation of thermohaline intrusions from an initial state that is stably stratified in two diffusing components. The intrusions form in a layer that contains compensating horizontal gradients of the two components and that lies above a denser reservoir layer that is homogeneous. In the initial state, a vertical barrier separates the upper layer into two half layers each with a different concentration but with the same density. Differential diffusion of solute from the reservoir into the upper layer initiates intrusions that are separated by an interface and that …

Preformed Phosphate, Soft Tissue Pump And Atmospheric Co2, Takamitsu Ito, Michael J. Follows

Journal of Marine Research

We develop a new theory relating atmospheric pCO₂ and the efficiency of the soft tissue pump of CO₂ in the ocean, measured by P*, a quasi-conservative tracer. P* is inversely correlated with preformed phosphate, and its global average represents the fraction of nutrients transported by the export and remineralization of organic material. This view is combined with global conservation constraints for carbon and nutrients leading to a theoretical prediction for the sensitivity of atmospheric pCO₂ to changes in globally averaged P*. The theory is supported by sensitivity studies with a more complex, …
