Lakes As Buffers Of Stream Dissolved Organic Matter (Dom) Variability: Temporal Patterns Of Dom Characteristics In Mountain Stream-Lake Systems, K. J. Goodman, Michelle A. Baker, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Lakes within fluvial networks may affect dissolved organic matter (DOM) dynamics in streams by dampening spring DOM snowmelt flushing responses and/or by increasing summer DOM production. We assessed the temporal variability of dissolved organic carbon (DOC) concentration and DOM characteristics (specific ultraviolet absorbance (SUVA254); DOC:dissolved organic nitrogen (DOC:DON)), as well as DOC export in seven paired lake inflows and outflows in the Sawtooth Mountain lake district, Idaho. We hypothesized that lakes would decrease stream DOM temporal variability and increase DOM export as a result of autotrophic production. We correlated DOM variability with landscape factors to evaluate potential drivers of DOM …

Health Literacy Dallas, Matthew C. Gayer, Mary C. Corey, Austin Prentice, Michael G. Hammack, Stephen T. Armstrong, Vanessa Mavec, Patrick Probst, Vincent J. Rossi

Big iDeas 2011 Proposals

Health literacy is a major issue in American health. Health literacy pertains to how patients obtain, understand, and use health information, as well as how medical professionals communicate medical information to their patients and the public. The economic costs of health literacy are conservatively estimated at over $70 billion annually in the United States. With recent alterations to the JCAHO standards, as well as pressure from new medical reimbursement legislation, the economics of health communication are only increasing in importance. More importantly though, is the human impact health literacy issues have on Americans. One in seven Americans struggle t read …

Carbon Offshoring: The Legal And Regulatory Framework For Coal Exports, Daniel M. Firger, Robert Denicola, Katherine English, Daniel Raichel, Ross Wolfarth, Kennan Zhong

Sabin Center for Climate Change Law

This report examines the legal and regulatory framework for U.S. coal exports, focusing in particular on the significant improvements in railroad and port infrastructure that will be necessary in order to boost the volume of overseas coal shipments to the degree anticipated by recent industry projections. While existing railroads and ports have the capacity to handle current coal export volumes, much more infrastructure will be needed to meet surging foreign demand. A wide variety of new construction projects are under consideration to expand capacity and relieve congestion. These range from double-tracking existing Class I railroad rights of way to dredging …

Memorandum On China’S Measures For Addressing Sea Level Change, Zhang Zhongmin

Sabin Center for Climate Change Law

This paper describes the current state of China’s recognition of sea level rise in the context of global climate change. The author analyzes official state documents addressing sea level rise, including the annual China Sea Level Communiqué, and compares them with local government initiatives and perspectives from non-governmental sources such as academia, NGOs and the general public. The paper concludes that, while China has taken many commendable steps towards addressing sea level rise, there are still considerable obstacles to be overcome. Finally, the author recommends that local governmental and non-governmental actors play a larger and better defined role. The author …

Paraffin: An Economic And Ecological Alternative For Bone Conservation, Victoria E. Luksha

Graduate Student Theses, Dissertations, & Professional Papers

Fragile bone materials are ubiquitous in archaeological museum and forensic settings. Although there are many chemical and industrial options for conservation, these may adversely affect the bone objects undergoing preservative treatment. Here, paraffin is explored as a biologically friendly alternative to bone material conservation. Modern domestic pig ribs were subjected to paraffin treatment and then to isotopic analysis to quantify and investigate the chemical effects of paraffin. Although the results showed that paraffin had a limited impact, the sample size proved too small to display the definitive parameters of paraffin’s effects. The results were nevertheless compelling enough to warrant more …

Corticosterone As A Mediator Of The Tradeoff Between Survival And Reproduction, Stephen Harold Patterson

Graduate Student Theses, Dissertations, & Professional Papers

Organisms cannot simultaneously maximize their investment in survival and reproductive success, thus these traits are said to trade off against one another. The physiological mechanisms that help guide these investment decisions are not fully understood. Stress-induced corticosterone is a strong candidate mechanism, because it is thought to promote survival-oriented behavior and physiology at the expense of non-critical functions such as reproduction. In this dissertation, I studied multiple components of corticosterone physiology (baseline corticosterone and stress-induced corticosterone) in several species of passerine birds to address this question from a variety of angels. I first provide direct support for corticosterone playing a …

Evaluating Repeat Photography In Documenting Natural And Cultural Landscape Changes: A Changing Crown Of The Continent Ecosystem Between 1899 And 2010, Dusty Leigh Waltner

Graduate Student Theses, Dissertations, & Professional Papers

Photography can be an invaluable tool in human geographical research, for example, to better understand the importance of place to people. Increasingly, geographers are looking at how photography can play an active role in the construction of geographical knowledge, that is, how photographs are seen rather than what they show. This study examines the use of repeat photography as a research method by conducting a case study on landscape change in the Crown of the Continent Ecosystem. Grounded in extensive archival research on the past, present, and future uses of photography as a research method, a repeat photography survey was …

Synthesis Of NB-Aryl-Aspartamides, NA-Arylamide-Aspartates, And Hydroxy-L-Proline Derivatives As Inhibitors Of Amino Acid Transport For Evaluating The Glutamine / Glutamate Cycle, Brent Russell Lyda

Graduate Student Theses, Dissertations, & Professional Papers

The glutamate / glutamine cycle is most traditionally described as the recycling of L-glutamate and L-glutamine via a concerted effort by a variety of cell membrane spanning amino acid transporters and amino acid converting enzymes, glutaminase and glutamine synthetase. This work details the design and synthesis of amino acid analogs, based off of an L-aspartate or L-proline scaffold, to be evaluated as inhibitors of the amino acid transporters ASCT (subtypes 1 & 2) and the excitatory amino acid transporters EAATs (subtypes 1-3), both involved in the glutamate / glutamine cycle. Furthermore, we have identified a number of potent substrate and …

Listen To The Bones: An Analysis Of The Variation Within The Faunal Remains At The Bridge River Site, Ogden Wyatt Ward

Graduate Student Theses, Dissertations, & Professional Papers

Analysis of faunal material from the 2008 and 2009 excavations at the Bridge River site (EeR14) show that variation exists within the assemblages, particularly through time between the occupation phases of Bridge River 2 and Bridge River 3. The data show that reliance on anadromous salmon (Oncorhynchus sp.) remain an important food source between Bridge River (BR) 2 and Bridge River 3 occupation phases, while reliance on important secondary resources, particularly deer (odocoileus sp.) increases. A shift in the distribution of elements from deer remains suggests a change in subsistence strategies that were used to harvest theses animals. It is …

Microbial Community Assembly And Diversification Of The Genus Chloroflexus Along An Alkaline Hot Spring Gradient, Michael Louis Weltzer

Graduate Student Theses, Dissertations, & Professional Papers

This research aims to achieve a greater understanding of the structure of bacterial communities present in alkaline hot springs in Yellowstone National Park. I focus specifically on White Creek and Rabbit Creek in the Lower Geyser Basin. I show that, overall, the bacterial communities of both creeks are non-randomly assembled. However, at finer taxonomic scales, bacterial groups differ in their community assembly patterns. Specifically, phototrophic groups show the strongest evidence for non-random assembly, most likely due to competition for light. A major exception to this pattern is the genus Chloroflexus, a major member of these communities. Members of this genus …

Dose-Dependent Thresholds Of 10-Ns Electric Pulse Induced Plasma Membrane Disruption And Cytotoxicity In Multiple Cell Lines, Bennett L. Ibey, Caleb C. Roth, Andrei G. Pakhomov, Joshua A. Bernhard, Gerald J. Wilmink, Olga N. Pakhomova

Bioelectrics Publications

In this study, we determined the LD50 (50% lethal dose) for cell death, and the ED50 (50% of cell population staining positive) for propidium (Pr) iodide uptake, and phosphatidylserine (PS) externalization for several commonly studied cell lines (HeLa, Jurkat, U937, CHO-K1, and GH3) exposed to 10-ns electric pulses (EP). We found that the LD50 varied substantially across the cell lines studied, increasing from 51 J/g for Jurkat to 1861 J/g for HeLa. PS externalized at doses equal or lower than that required for death in all cell lines ranging from 51 J/g in Jurkat, to 199 J/g in CHO-K1. Pr …

Nanosecond Pulsed Electric Field Induced Cytoskeleton, Nuclear Membrane And Telomere Damage Adversely Impact Cell Survival, Michael W. Stacey, P. Fox, S. Buescher, Juergen F. Kolb

Bioelectrics Publications

We investigated the effects of nanosecond pulsed electric fields (nsPEF) on three human cell lines and demonstrated cell shrinkage, breakdown of the cytoskeleton, nuclear membrane and chromosomal telomere damage. There was a differential response between cell types coinciding with cell survival. Jurkat cells showed cytoskeleton, nuclear membrane and telomere damage that severely impacted cell survival compared to two adherent cell lines. Interestingly, disruption of the actin cytoskeleton in adherent cells prior to nsPEF exposure significantly reduced cell survival. We conclude that nsPEF applications are able to induce damage to the cytoskeleton and nuclear membrane. Telomere sequences, regions that tether and …

The Panic Defense And Model Rules Common Sense: A Practical Solution For A Twenty-First Century Ethical Dilemma, Teresa M. Garmon

Georgia Law Review

The attorney-client relationshipremains one of the most
highly regarded associations in society and is of
indispensable importance for criminal defendants, but it
is not a relationship that lasts forever. The Model Rules of
Professional Conduct (Model Rules) not only allow
breaking this affiliation, but also sometimes demand it.
Yet, in other circumstances, the Model Rules and judicial
custom may force an attorney to proceed with a
representation-even in the face of fundamental
disagreement with the core defense in a criminal case.
Through the avenue of the gay panic defense, this Note
explores how attorneys can become trapped between their
own …

Seen But Not Heard: An Argument For Granting Evidentiary Hearings To Weigh The Credibility Of Recanted Testimony, Michael M. Hill

Georgia Law Review

The case of Troy Davis shows how difficult it is for a
convicted criminal defendant to obtain postconviction
review of witness recantations. Convicted of murder on
the testimony of nine eyewitnesses, Davis spent over a
decade petitioning for judicial review of the recantations of
seven of those witnesses before the U.S. Supreme Court
ordered an evidentiary hearing in 2009. Concurrently, the
DNA revolution continued to prove the innocence of an
increasing number of convicted inmates across the nation,
and the majority of those convictions had relied on
eyewitness testimony. If these scientific advances suggest
that eyewitness identification is not as …

Targeted Identification Of Metastasis-Associated Cell-Surface Sialoglycoproteins In Prostate Cancer, Lifang Yang, Julius O. Nyalwidhe, Sigi Guo, Richard R. Drake, O. John Semmes

Bioelectrics Publications

Covalent attachment of carbohydrates to proteins is one of the most common post-translational modifications. At the cell surface, sugar moieties of glycoproteins contribute to molecular recognition events involved in cancer metastasis. We have combined glycan metabolic labeling with mass spectrometry analysis to identify and characterize metastasis-associated cell surface sialoglycoproteins. Our model system used syngeneic prostate cancer cell lines derived from PC3 (N2, nonmetastatic, and ML2, highly metastatic). The metabolic incorporation of AC₄ManNAz and subsequent specific labeling of cell surface sialylation was confirmed by flow cytometry and confocal microscopy. Affinity isolation of the modified sialic-acid containing cell surface proteins …

An Apoptosis Targeted Stimulus With Nanosecond Pulsed Electric Fields (Nspefs) In E4 Squamous Cell Carcinoma, Wei Ren, Stephen J. Beebe

Bioelectrics Publications

Stimuli directed towards activation of apoptosis mechanisms are an attractive approach to eliminate evasion of apoptosis, a ubiquitous cancer hallmark. In these in vitro studies, kinetics and electric field thresholds for several apoptosis characteristics are defined in E4 squamous carcinoma cells (SCC) exposed to ten 300 ns pulses with increasing electric fields. Cell death was [95% at the highest electric field and coincident with phosphatidylserine externalization, caspase and calpain activation in the presence and absence of cytochrome c release, decreases in Bid and mitochondria membrane potential (Δψm) without apparent changes reactive oxygen species levels or in Bcl2 and Bclxl levels. …

The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Heat Stress: Evidence For Differential Thermal Sensitivities, Loredana Serafini

Master's Theses

The sea squirts Ciona intestinalis and C. savignyi have disparate distribution patterns, which may result from differences in their thermal tolerance limits. Because C. intestinalis, an almost cosmopolitan species, has a more widespread distribution, it is thought that it is better adapted to endure a wide range of temperatures. In order to compare the heat stress response between these two congeners, we studied global changes in protein expression, using a proteomics approach. To characterize the response to extreme heat stress, animals of both species were exposed to temperatures of 22°C, 25°C, and 28°C for 6 h, and then were …

Can Sheep Control Leafy Spurge Without Compromising Efforts To Restore Native Plants?, Eva S. Masin

Graduate Student Theses, Dissertations, & Professional Papers

This thesis includes two studies on the ecological effects of using sheep to control Euphorbia esula (leafy spurge). While sheep can effectively reduce E. esula when used as a long-term management strategy, little is known about their impacts on native plants. The efficacy of sheep grazing for restoration depends both on its potential for controlling undesirable plants and its ability to promote native species that provide key ecosystem goods and services. I investigated the effects of sheep grazing on native plants at both seed and mature-plant stages. To assess impacts on seedling establishment, I measured density of forb and graminoid …
