Role Of Nucleation In Cortical Microtubule Array Organization: Variations On A Theme, Erica A. Fishel, Ram Dixit Jul 2013

Role Of Nucleation In Cortical Microtubule Array Organization: Variations On A Theme, Erica A. Fishel, Ram Dixit

Biology Faculty Research

The interphase cortical microtubules (CMTs) of plant cells form strikingly ordered arrays in the absence of a dedicated microtubule-organizing center. Considerable research effort has focused on activities such as bundling and severing that occur after CMT nucleation and are thought to be important for generating and maintaining ordered arrays. In this review, we focus on how nucleation affects CMT array organization. The bulk of CMTs are initiated from γ-tubulin-containing nucleation complexes localized to the lateral walls of pre-existing CMTs. These CMTs grow either at an acute angle or parallel to the pre-existing CMT. Although the impact of microtubule-dependent nucleation is …

Lessons From Japan: Resilience After Tokyo And Fukushima, Michelle L. Spencer Jul 2013

Lessons From Japan: Resilience After Tokyo And Fukushima, Michelle L. Spencer

Journal of Strategic Security

In the spring of 1995 Japan experienced the world’s first major terrorist attack using chemical weapons by a little-known religious cult called Aum Shinrikyo. The attack on the Tokyo subway, which killed 13 people, was the first lethal case of a non-state actor using a chemical agent against a civilian population. In March 2011, following a 9.0 magnitude earthquake in Japan, the Fukushima Daiichi nuclear reactor experienced a full meltdown releasing radiation into the surrounding area. The seemingly unhurried government reaction provided conflicting information to Japanese citizens, slowing evacuation and protective actions. Government failure is cited as a significant factor …

Survey Of Well Water Contamination In A Rural Southwestern Pennsylvania Community With Unconventional Shale Gas Drilling, Shyama Karen Alawattegama Jul 2013

Survey Of Well Water Contamination In A Rural Southwestern Pennsylvania Community With Unconventional Shale Gas Drilling, Shyama Karen Alawattegama

Electronic Theses and Dissertations

The recent increase in unconventional shale gas extraction (USGE) using hydraulic fracturing and associated claims of ground water contamination has raised awareness of ground water issues. The Woodlands, a community that relies on well water, reported changes in water quality and yield concurrent with USGE activities. In an effort to determine the extent of the issues and if a correlation existed, residents participated in a survey and well water samples were collected and analyzed. Base maps of the study area were created identifying current horizontal wells, legacy operations (e.g., gas and oil wells, coal mining), and topography. Fifty-six out of …

Environmental Law, Travis M. Trimble Jul 2013

Environmental Law, Travis M. Trimble

Mercer Law Review

In 2012, the United States Court of Appeals for the Eleventh Circuit, deciding an issue of first impression, held that a party that enters a consent order to settle potential liability under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is not entitled to pursue a cost recovery action against other potentially responsible parties under section 107 of the Act, but may only seek contribution from those parties under section 113(f) of the Act. The court also affirmed a decision by the Bureau of Ocean Energy Management to approve an exploration plan for oil and gas drilling in the …

Same-Sex Divorce In The United States: Protecting The Interests Of The Children, Joan Catherine Bohl Jul 2013

Same-Sex Divorce In The United States: Protecting The Interests Of The Children, Joan Catherine Bohl

University of Miami Race & Social Justice Law Review

In light of recent political, legal, and legislative developments, the status of same-sex couples across the United States has become increasingly complex. This article focuses on the issue of same-sex divorce in a mobile society. When a same-sex couple moves from a state recognizing same-sex marriage—or from Canada—to a state that does not expressly recognize same-sex marriage, dissolution of that marriage can become a byzantine problem much more complex than a state’s “official” position on same-sex marriage. Relevant factors can range from the state’s legislative and executive pronouncements affecting homosexual citizens in areas such as pension benefits and health plans …

Removal Of The Impediment: The State Of Transgender Marriage In Montana, Wesley Parks Jul 2013

Removal Of The Impediment: The State Of Transgender Marriage In Montana, Wesley Parks

Montana Law Review

As of the date of this article, no Montana court has explicitly addressed transgender marriage. Of the numerous state courts outside Montana that have addressed transgender marriage, traditional, objective definitions of sex were used that fail to protect the privacy of transgender people and fail to apply laws equally throughout the entire transgender community. This article surveys in depth those out-of-state cases to illustrate the inconsistent reasoning courts have applied when addressing transgender marriage. Then, this article examines contemporary Montana cases regarding gay and lesbian privacy and equal protection. Synthesizing these sources, this article suggests that Montana pioneer transgender marriage …

Exploring Epigenetic Regulation Of Fear Memory And Biomarkers Associated With Post-Traumatic Stress Disorder, Stephanie A. Maddox, Glenn E. Schafe, Kerry J. Ressler Jul 2013

Exploring Epigenetic Regulation Of Fear Memory And Biomarkers Associated With Post-Traumatic Stress Disorder, Stephanie A. Maddox, Glenn E. Schafe, Kerry J. Ressler

Publications and Research

This review examines recent work on epigenetic mechanisms underlying animal models of fear learning as well as its translational implications in disorders of fear regulation, such as Post-traumatic Stress Disorder (PTSD). Specifically, we will examine work outlining roles of differential histone acetylation and DNA-methylation associated with consolidation, reconsolidation, and extinction in Pavlovian fear paradigms. We then focus on the numerous studies examining the epigenetic modifications of the Brain-derived neurotrophin factor (BDNF) pathway and the extension of these findings from animal models to recent work in human clinical populations. We will also review recently published data on FKBP5 regulation of …

Does Boyer’S Integrated Scholarships Model Work On The Ground? An Adaption Of Boyer’S Model For Scholarly Professional Development, William E. Boyd Jul 2013

Does Boyer’S Integrated Scholarships Model Work On The Ground? An Adaption Of Boyer’S Model For Scholarly Professional Development, William E. Boyd

International Journal for the Scholarship of Teaching & Learning

Boyer’s model of four scholarships as an integrated system engaging and integrating the scholarships of discovery, integration, application, and teaching is being increasingly adopted both by individual scholars and institutions. Here I reflect on my own adoption of this approach almost a decade ago, and I describe one application, its use in defining my professional academic profile. While this does not directly address issues of pedagogy, it provides a sound basis for improved pedagogical practice in higher education. I assess my adoption of Boyer’s model against several benchmarks grounded in the social life of academe: success of promotion; mentoring peers …

Analysis Of Synephrine Content In Bitter Orange (Citrus Aurantium L.) Dietary Supplements, Martha L. Newell Jul 2013

Analysis Of Synephrine Content In Bitter Orange (Citrus Aurantium L.) Dietary Supplements, Martha L. Newell

Theses and Dissertations

Many Americans are either currently taking, or have recently taken, non-prescription dietary supplements. These supplements claim to help prevent or relieve any number of ailments, but are not regulated by any governing body. One common use of dietary supplements is to aid in weight loss. Synephrine, the most abundant active component in bitter orange (Citrus aurantium L.) extracts, became a regular ingredient in weight loss supplements after the 2004 ephedra ban. The initial goal of this research was to use reverse phase high performance liquid chromatography (HPLC) to determine the synephrine content of five dietary supplements and compare …

Fiber Pigtailed Thin Wall Capillary Coupler For Excitation Of Microsphere Wgm Resonator, Haining Wang, Xinwei Lan, Jie Huang, Lei Yuan, Cheol-Woon Kim, Hai Xiao Jul 2013

Fiber Pigtailed Thin Wall Capillary Coupler For Excitation Of Microsphere Wgm Resonator, Haining Wang, Xinwei Lan, Jie Huang, Lei Yuan, Cheol-Woon Kim, Hai Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we demonstrate a fiber pigtailed thin wall capillary coupler for excitation of Whispering Gallery Modes (WGMs) of microsphere resonators. The coupler is made by fusion-splicing an optical fiber with a capillary tube and consequently etching the capillary wall to a thickness of a few microns. Light is coupled through the peripheral contact between inserted microsphere and the etched capillary wall. The coupling efficiency as a function of the wall thickness was studied experimentally. WGM resonance with a Q-factor of 1.14 x 104 was observed using a borosilicate glass microsphere with a diameter of 71 µm. The …

Microwave Assisted Reconstruction Of Optical Interferograms For Distributed Fiber Optic Sensing, Jie Huang, Lei Hua, Xinwei Lan, Tao Wei, Hai Xiao Jul 2013

Microwave Assisted Reconstruction Of Optical Interferograms For Distributed Fiber Optic Sensing, Jie Huang, Lei Hua, Xinwei Lan, Tao Wei, Hai Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

This paper reports a distributed fiber optic sensing technique through microwave assisted separation and reconstruction of optical interferograms in spectrum domain. The approach involves sending a microwave-modulated optical signal through cascaded fiber optic interferometers. The microwave signal was used to resolve the position and reflectivity of each sensor along the optical fiber. By sweeping the optical wavelength and detecting the modulation signal, the optical spectrum of each sensor can be reconstructed. Three cascaded fiber optic extrinsic Fabry-Perot interferometric sensors were used to prove the concept. Their microwave-reconstructed interferogram matched well with those recorded individually using an optical spectrum analyzer. The …

From Questions To Effective Answers: On The Utility Of Knowledge-Driven Querying Systems For Life Sciences Data, Amir H. Asiaee, Prashant Doshi, Todd Minning, Satya S. Sahoo, Priti Parikh, Amit P. Sheth, Rick L. Tarleton Jul 2013

From Questions To Effective Answers: On The Utility Of Knowledge-Driven Querying Systems For Life Sciences Data, Amir H. Asiaee, Prashant Doshi, Todd Minning, Satya S. Sahoo, Priti Parikh, Amit P. Sheth, Rick L. Tarleton

Kno.e.sis Publications

We compare two distinct approaches for querying data in the context of the life sciences. The first approach utilizes conventional databases to store the data and provides intuitive form-based interfaces to facilitate querying of the data, commonly used by the life science researchers that we study. The second approach utilizes a large OWL ontology and the same datasets associated as RDF instances of the ontology. Both approaches are being used in parallel by a team of cell biologists in their daily research activities, with the objective of gradually replacing the conventional approach with the knowledge-driven one. We describe several benefits …

Increase In Acc Oxidase Levels And Activities During Paradormancy Release Of Leafy Spurge (Euphorbia Esula) Buds, Wun S. Chao, Marcelo Serpe, Jeffrey C. Suttle, Ying Jia Jul 2013

Increase In Acc Oxidase Levels And Activities During Paradormancy Release Of Leafy Spurge (Euphorbia Esula) Buds, Wun S. Chao, Marcelo Serpe, Jeffrey C. Suttle, Ying Jia

Biology Faculty Publications and Presentations

The plant hormone ethylene is known to affect various developmental processes including dormancy and growth. Yet, little information is available about the role of ethylene during paradormancy release in underground adventitious buds of leafy spurge. In this study, we examined changes in ethylene evolution and the ethylene biosynthetic enzyme ACC oxidase following paradormancy release (growth induction). Our results did not show an obvious increase in ethylene during bud growth. However, when buds were incubated with 1 mM ACC, ethylene levels were higher in growing than non-growing buds, suggesting that the levels of ACC oxidase increased in growing buds. Real-time qPCR …

Distinct Iron Isotopic Signatures And Supply From Marine Sediment Dissolution, William B. Homoky, Seth G. John, Tim M. Conway, Rachel A. Mills Jul 2013

Distinct Iron Isotopic Signatures And Supply From Marine Sediment Dissolution, William B. Homoky, Seth G. John, Tim M. Conway, Rachel A. Mills

School of Geosciences Faculty and Staff Publications

Oceanic iron inputs must be traced and quantified to learn how they affect primary productivity and climate. Chemical reduction of iron in continental margin sediments provides a substantial dissolved flux to the oceans, which is isotopically lighter than the crust, and so may be distinguished in seawater from other sources, such as wind-blown dust. However, heavy iron isotopes measured in seawater have recently led to the proposition of another source of dissolved iron from ‘non-reductive’ dissolution of continental margins. Here we present the first pore water iron isotope data from a passive-tectonic and semi-arid ocean margin (South Africa), which reveals …

Carnivore Use Of Avocado Orchards Across An Agricultural-Wildland Gradient, Theresa M. Nogeire, Frank W. Davis, Jennifer Duggan, Kevin R. Crooks, Erin E. Boydston Jul 2013

Carnivore Use Of Avocado Orchards Across An Agricultural-Wildland Gradient, Theresa M. Nogeire, Frank W. Davis, Jennifer Duggan, Kevin R. Crooks, Erin E. Boydston

AES Faculty Publications and Presentations

Wide-ranging species cannot persist in reserves alone. Consequently, there is growing interest in the conservation value of agricultural lands that separate or buffer natural areas. The value of agricultural lands for wildlife habitat and connectivity varies as a function of the crop type and landscape context, and quantifying these differences will improve our ability to manage these lands more effectively for animals. In southern California, many species are present in avocado orchards, including mammalian carnivores. We examined occupancy of avocado orchards by mammalian carnivores across agricultural-wildland gradients in southern California with motion-activated cameras. More carnivore species were detected with cameras …

Resonant Characteristics Of Rectangular Hammerhead Microcantilevers Vibrating Laterally In Viscous Liquid Media, Jinjin Zhang, Fabien Josse, Stephen M. Heinrich, Nicholas J. Nigro, Isabelle Dufour, Oliver Brand Jul 2013

Resonant Characteristics Of Rectangular Hammerhead Microcantilevers Vibrating Laterally In Viscous Liquid Media, Jinjin Zhang, Fabien Josse, Stephen M. Heinrich, Nicholas J. Nigro, Isabelle Dufour, Oliver Brand

Civil and Environmental Engineering Faculty Research and Publications

The resonant characteristics of laterally vibrating rectangular hammerhead microcantilevers in viscous liquid media are investigated. The rectangular hammerhead microcantilever is modeled as an Euler-Bernoulli beam (stem) and a rigid body (head). A modified semi-analytical expression for the hydrodynamic function in terms of the Reynolds number, Re, and aspect ratio, h/b, is proposed to rapidly evaluate the sensing characteristics. Using this expression, the resonance frequency, quality factor and normalized surface mass sensitivity are investigated as a function of the dimensions of the microcantilever and liquid properties. Guidelines for design of hammerhead microcantilever geometry are proposed to achieve efficient sensing platforms for …

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Solomon Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek Jul 2013

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Solomon Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek

Forest Management Faculty Publications

Recent research on mountain-dwelling species has illustrated changes in species' distributional patterns in response to climate change. Abundance of a species will likely provide an earlier warning indicator of change than will occupancy, yet relationships between abundance and climatic factors have received less attention. We tested whether predictors of counts of American pikas (Ochotona princeps) during surveys from the Great Basin region in 1994-1999 and 2003-2008 differed between the two periods. Additionally, we tested whether various modeled aspects of ecohydrology better predicted relative density than did average annual precipitation, and whether risk of site-wide extirpation predicted subsequent population counts of …

Animals Represent The Past And The Future, Thomas R. Zentall Jul 2013

Animals Represent The Past And The Future, Thomas R. Zentall

Psychology Faculty Publications

It has been proposed by some that only humans have the ability to mentallytravel back in time (i.e., have episodic memory) and forward in time (i.e., have the ability to simulate the future). However, there is evidence from a variety of nonhuman animals (e.g., primates, dolphins, scrub jays, rats, and pigeons) that they have some ability to recover personal memories of what-where-when an event occurred (an earlier requirement of the ability to recover an episodic memory) and answer unexpected questions (another requirement to distinguish between semantic and episodic memory). Also, perhaps more critically, according to Tulving’s more recent definition of …

How Folk Beliefs About Free Will Influence Sentencing: A New Target For The Neuro-Determinist Critics Of Criminal Law, Emad H. Atiq Jul 2013

How Folk Beliefs About Free Will Influence Sentencing: A New Target For The Neuro-Determinist Critics Of Criminal Law, Emad H. Atiq

Cornell Law Faculty Publications

Do recent results in neuroscience and psychology that portray our choices as predetermined threaten to undermine the assumptions about "free will" that drive criminal law? This article answers in the affirmative, and offers a novel argument for the transformative import of modern science. It also explains why a revision in the law's assumptions is morally desirable. Problematic assumptions about free will have a role to play in criminal law not because they underlie substantive legal doctrine or retributive theory, but because everyday actors in the sentencing process are authorized to make irreducibly moral determinations outside of the ordinary doctrinal framework. …

Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan Jul 2013

Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan

Master's Theses or Doctor of Nursing Practice

The objective of this project was to determine the degree and direction of association between the amount of mud/salt flat area and shorebird abundance during spring and early summer. This study used Landsat 5 to indirectly measure mudflat and salt flat areas at two wetland complexes within Kansas over a period of several years (1991-2008). These measurements were compared to shorebird surveys conducted by several individuals at both Quivira National Wildlife Refuge and Cheyenne Bottoms Wildlife Area. A correlation analysis showed that significant relationships exist between mud/salt flat area and the abundance of certain shorebird species. Correlation coefficients for individual …
