The Effect Of Z-Binding Yarns On The Electrical Properties Of 3d Woven Composites, Mohamed Nasr Saleh, Arief Yudhanto, Gilles Lubineau, Constantinos Soutis

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Electrical resistance monitoring (ERM) has been used to study the effect of the z-binding yarns on the initial electrical resistance (ER) and its change of three architectures of 3D woven carbon fiber composites namely (orthogonal "ORT", layer-to-layer "LTL" and angle interlock "AI") when tested in tension. Specimens are loaded in on-axis "warp" and off-axis "45°" directions. In situ ERM is achieved using the four-probe technique. Monotonic and cyclic "load/unload" tests are performed to investigate the effect of piezo-resistivity and residual plasticity on resistance variation. The resistance increases for the off-axis loaded specimens (∼90%) is found to be higher than that …

Data From: Target Sequence Capture Of Nuclear-Encoded Genes For Phylogenetic Analysis In Ferns, Paul G. Wolf, Tanner A. Robison, Matthew G. Johnson, Michael A. Sundue, Weston L. Testo, Carl J. Rothfels

Browse all Datasets

Premise of the study: Until recently, most phylogenetic studies of ferns were based on chloroplast genes. Evolutionary inferences based on these data can be incomplete because the characters are from a single linkage group and are uniparentally inherited. These limitations are particularly acute in studies of hybridization, which is prevalent in ferns; fern hybrids are common and ferns are able to hybridize across highly diverged lineages, up to 60 million years since divergence in one documented case. However, it not yet clear what effect such hybridization has on fern evolution, in part due to a paucity of available biparentally inherited …

The Future Of Nuclear Security: A Medical Physicist’S Perspective, Katharine E. Thomson

International Journal of Nuclear Security

Planning for the future of nuclear security is a vital and complex task, requiring cooperation and contribution from many disciplines and industries. This diversity of expertise should include the medical sector, which faces many of the same challenges as the nuclear industry: controlling access to dangerous material, creating a strong security culture, cooperating with the wider world and engaging the public.

Medical physicists, of which the author is one, oversee all aspects of small-scale radiation use. This paper discusses three key areas increasingly important to both medical and nuclear uses of radioactive materials: public engagement, prevention of nuclear and radiological …

An Evidence-Based Implementation Project On High Utilizers In The Emergency Department, Bernadette Martin Ruggles

Doctor of Nursing Practice (DNP) Projects

Abstract

Challenges have been presented to the Emergency Department (ED) over the last several years as the dramatic rise in health insurance enrollment continues. Although, with the Republican bill, the American Health Care Act, changes to Medicaid may alter the health program leaving many uncertainties (Kaplan & Pear, 2017). Evidence reflects EDs are inundated with even more patients taking advantage of the availability of a one-stop shop for their care and treatment. Costs of ED services and resource allocation are rising as a result of these unnecessary visits contributing to a total healthcare expenditure of approximately 17.6% of the US …

Teaching A Primary Prevention Falls Program: Using The Stop Elderly Accidents, Deaths, And Injuries (Steadi) Toolkit, Janice Mark

Doctor of Nursing Practice (DNP) Projects

Problem: Falls in the community dwelling older adult (CDOA) are a growing health concern, placing large financial and social burdens. Primary care providers (PCPs) are not engaging in falls assessment and prevention activities due to the lack of knowledge and time. Context: Falls are the leading cause of fatal and nonfatal injuries, and is projected to worsen with the increase in the aging population. STEADI is a fall assessment and prevention toolkit created by the CDC to tackle this problem designed to address the knowledge and practice gaps of PCPs. Interventions: A DNP project was crafted and implemented to train …

Leadership Development, Succession Planning And Simulation: A Succession Plan For Organizational Success, Beth Eichenberger

Doctor of Nursing Practice (DNP) Projects

Future executive nurse leaders must be identified and prepared for the challenges of 21st century health care. The literature suggests a lack of existing standardized succession plans for these leaders. Senior leaders are often faced with the complex issue of how to develop and validate the competencies required for these leadership roles (Dyess, Sherman, Pratt, & Chiang- Hanisko, 2016). Therefore, in the absence of a succession plan, creating a leadership development program, which provides a pipeline of new executive leaders, would alleviate this gap. The motivating force is an effort to promote current talent and provide a higher level of …

Evaluation Of Genetic Diversity And Stability Of Colocasia Cultivars Using Issr, Seukmin Hong

Electronic Theses and Dissertations

Using 44 ornamental Colocasia cultivars planted at Stephen F. Austin State University (Nacogdoches, TX), cultivar assessment, genetic diversity, stability, and relationship were examined with banding patterns produced from Inter-simple sequence repeat (ISSR) markers. Comparing banding patterns of vegetatively propagated clones of each cultivar, genetic stability was examined. Unweighted pair group method with arithmetic mean (UPGMA) and principal coordinate analysis (PCO) were performed to examine genetic relationship that can explain a need for the new classification Colocasia gigantea and recent movement of re-classifying Colocasia antiquorum. Average Shannon’s diversity index for all loci was found to quantify genetic diversity. The genetic …

Biteau, S. G. Blaess

Faculty Publications

We present a new method for probing the hadronic interaction models at ultrahigh energy and extracting details about mass composition. This is done using the time profiles of the signals recorded with the water-Cherenkov detectors of the Pierre Auger Observatory. The profiles arise from a mix of the muon and electromagnetic components of air showers. Using the risetimes of the recorded signals, we define a new parameter, which we use to compare our observations with predictions from simulations. We find, first, inconsistencies between our data and predictions over a greater energy range and with substantially more events than in previous …

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signal-to-noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars …

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much of which was not explored in initial LIGO. The search was made possible by the computing power provided by the volunteers of the Einstein@Home project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population, corresponding to a sensitivity depth of 48.7 …

Context-Dependent Chemosensory Signaling, Aggression And Neural Activation Patterns In Gravid Female African Cichlid Fish, Karen E. Field, Karen P. Maruska

Faculty Publications

© 2017. Published by The Company of Biologists Ltd . Social animals must constantly assess their environment to make appropriate behavioral decisions. The use of various sensory modalities is imperative in this process and it is hypothesized that the highly conserved brain nuclei comprising the social decisionmaking network (SDMN) integrates social information with an animal's internal state to elicit behavioral responses. Here, we used the highly social African cichlid fish, Astatotilapia burtoni, to investigate whether reproductively receptive (gravid) females show contextual chemosensory signaling, social behaviors and neural activation patterns within the SDMN. We exposed gravid females to different social contexts: …

Global Awakening Of Cryptic Biosynthetic Gene Clusters In Burkholderia Thailandensis, Ashish Gupta, Renesh Bedre, Sudarshan Singh Thapa, Afsana Sabrin, Guannan Wang, Maheshi Dassanayake, Anne Grove

Faculty Publications

© 2017 American Chemical Society. Many bacteria encode biosynthetic proteins that produce a vast array of natural products. These compounds are often synthesized during host invasion as they function as virulence factors. In addition, such secondary metabolites have yielded numerous molecular scaffolds with pharmaceutical and clinical importance. The gene clusters that encode proteins responsible for synthesis of these compounds are typically silenced or "cryptic" under laboratory growth conditions, hampering discovery of novel lead compounds. We report here that MftR is a global repressor of secondary metabolite synthesis in Burkholderia thailandensis and that urate functions as a physiologically relevant inducer of …

Characterization Of Pathogenic Vibrio Parahaemolyticus From The Chesapeake Bay, Maryland, Arlene J. Chen, Nur A. Hasan, Bradd J. Haley, Elisa Taviani, Mitch Tarnowski, Kathy Brohawn, Crystal N. Johnson, Rita R. Colwell, Anwar Huq

Faculty Publications

Vibrio parahaemolyticus is the leading cause of bacterial gastroenteritis associated with seafood consumption in the United States. Here we investigated the presence of virulence factors and genetic diversity of V. parahaemolyticus isolated from water, oyster, and sediment samples from the Chesapeake Bay, Maryland. Of more than 2,350 presumptive Vibrio collected, more than half were confirmed through PCR as V. parahaemolyticus, with 10 encoding both tdh and trh and 6 encoding only trh. Potentially pathogenic V. parahaemolyticus were then serotyped with O1:KUT and O3:KUT predominant. Furthermore, pulsed-field gel electrophoresis was performed and the constructed dendrogram displayed high diversity, as did results …

Invisible Invisibility, Eugina Song

Theses and Dissertations

White America assumes its culture is the default, and Asian culture as foreign and irrelevant. I address Asian invisibility by using canvas structure as a Western framing device of painting, and make this cultural barrier visible by breaking out of the frame. Deriving from Dansaekhwa, I challenge the Western painting structure with materiality.

Post-Representational Presence: Disruptive Actions & Visibility Politics In New Media, Christian Hendricks

Theses and Dissertations

This text is a written component to a master’s thesis in the fine arts. It is a research-intensive text that conventionally examines contemporary conditions of politics and modes of representation, and analyzes the most innovative artists and visual producers working in these areas. However, the text also includes exercise modules with “challenges” for the reader, similar to a textbook. In the modules, the examples provided are works of my own. I also include text, images, and documentation of my own work from my MFA thesis exhibition.

High-Di-High-Di-High-Di-High, Low-Di-Low-Di-Low-Di-Low, Daniel Figueredo

Theses and Dissertations

I am a believer in our image culture and its capacity to be liberating, exploratory, and critical. I also believe in its ability to overwhelm. My own work is a reaction to this over saturation. It is equally influenced by childhood exposure to remedial computer graphics and cartoons, as well as formative experiences traveling, an in-depth Art Historical education, and a love for art developed over time.
