A New Fluid-Structure Interaction Point-Projection Method, Philip Robert Ivancic

Theses and Dissertations

A new point-projection method was developed to transfer loads and displacements in a two-way coupled fluid-structure interaction problem. The existing method involved projecting the load at each computational fluid dynamics (CFD) node onto a corresponding computation structural dynamics (CSD) element. The load is distributed to the CSD nodes on that element. However, the solution is not unique and will vary the projection. In the new method, a rigid pyramid element is built upon the CSD element and that encompasses the CFD node. Thus, the CFD load will be uniquely distributed to the CSD nodes. After the CSD code updates the …

Thermomechanical Performance Assessment of Bio-based PU Adhesives Derived from Castor Oil

An Abstract of the Thesis by

Anand V. Patel

Adhesives play a critical role in binding diverse materials, thereby promoting structural integrity and functional versatility across numerous daily applications. A significant challenge remains in developing polyurethane adhesives that exhibit exceptional bonding strength, as many are derived from petroleum products. To reduce dependence on non-renewable resources and offer sustainable and affordable alternatives, vegetable oils are being utilized to create a range of polyurethane adhesives. These oils are preferred due to their low toxicity, cost-effectiveness, and reduced environmental impact. This research …

Reforming The U.S. Intelligence Community: Successes, Failures And The Best Path Forward, Christopher John Sheehy

Senior Honors Projects, 2010-2019

In the wake of the 9/11 and Iraqi WMD catastrophes, an increased spotlight was placed upon the U.S. Intelligence Community (IC). The widespread criticism of the IC, from both government and public sources, ultimately culminated in the Intelligence Reform and Terrorism Prevention Act (IRTPA) in 2004. Today, with a wide array of transnational threats to the homeland, as well as the complex, globalized, high-tech world they thrive in, the role of intelligence remains essential to the national security apparatus.

A new shape for the intelligence reform debate is necessary, one that recognizes the unique role the IC plays in policy …

Discrimination Of Duration Differences Of Typically Developing Children And Children With Suspected Childhood Apraxia Of Speech, Susan B. Ingram

Dissertations, 2014-2019

The speech sound disorder, childhood apraxia of speech (CAS), has perplexed clinicians and researchers for many years. The perplexity has stemmed, in part, from questions about identifying characteristics that distinguish it from other childhood speech disorders. Given the reported vowel duration deficits cited in the speech production of children with sCAS, the research for this population is deficient in assessing the ability of these children to discriminate vowel duration differences. The present study represents an initial attempt to address duration discrimination in a systematized experimental design for a group of school-age TD children (n = 21) and a smaller group …

The Interaction Of Patience And Resistance To Miserly Information Processing On Life Outcomes, Tristan Kirkman

Masters Theses, 2010-2019

This study examined the relationships between three factors: patience, resistance to miserly information processing (RMIP), and life outcomes. Patience, or the ability to delay gratification in exchange for a larger reward, has been associated with having fewer negative life outcomes— those who are able to wait tend to have better lives. RMIP involves the tendency to think analytically instead of using heuristics (mental shortcuts). RMIP has had only limited study in terms of its relationship to actual life outcomes, but what has been examined so far has also suggested a positive relationship. In the present study, it was found that …

An Exploration Of The Experience Of In-Home Counseling Services, Greg Czyszczon

Dissertations, 2014-2019

This qualitative study explores the lived experience of in-home counseling services by using a phenomenological method. In-home counseling services are used in situations where families experience extreme emotional distress, in part owing to the problematic behavior of a child. A semi-structured interview was used to elicit parents’ experience of in-home services in a geographical area that included a large portion of Virginia. The study found that the whole of parents’ experience of in-home services was dynamically influenced by constituent parts including the parent’s experience of the child, their experience of parenting, their experience of systems of care, and their experience …

Weighing In: Therapeutic Benefits Of Online Communities For Individuals With Eating Disorders, Cheri L. Greenfield

Educational Specialist, 2009-2019

The treatment of eating disorders involves a complex approach. In recent years, a number of websites have developed in an attempt to meet the needs of individuals struggling with this set of disorders. Some of these websites are nationally recognized organizations dedicated to improve treatment and provide educational resources, while other websites have been authored by individuals with eating disorders in an attempt to create a safe community of support. This project explores various components found in online communities, examines characteristics of eating disorders, and evaluates the worth of such resources, even when in perceived contrast with traditional treatment. Rather …

Comparison: Perception And Knowledge Of Protein Consumption In Female Athletes For Post Weight Lifting Recovery, Samantha Jane Lofton

Senior Honors Projects, 2010-2019

A study was conducted on James Madison University’s campus to assess the knowledge, beliefs, perceptions and habits of protein consumption post resistance training in female student athletes. Sixty-two female athletes who regularly partake in resistance training filled out a recovery-cue questionnaire containing 10 statements/questions on the subject of protein consumption. The data was analyzed using IBM SPSS, Version 21.0 and Microsoft Office Excel. Eight percent of respondents stated they are aware of how much protein they should be consuming post workout, and 21% feel what they consume post workout is an adequate amount of protein for muscle recovery. Forty-six percent …

The Effects Of Academic Libraries’ Resource, Expenditure, And Service Decisions On Library Use: An Analysis Of Acrl And Nces Data, Jody C. Fagan

Dissertations, 2014-2019

Academic libraries are key contributors to the instructional and research missions of their parent institutions, but often struggle to demonstrate specifically what they do and how that affects institutional outcomes. High-impact educational practices are one area where libraries make a difference, but where explicit connections between activities and outcomes are not always articulated. Faculty and graduate student research is another area where libraries’ contribution makes logical sense, but specific relationships are not necessarily drawn. Libraries may place different emphasis on these two areas, effectively choosing different business strategies, to support their institutions’ missions. Two national surveys collect data about library …

The Relationship Between Riparian Zone Width And Floristic Quality In Shenandoah County, Virginia, Jamie D. Smith

Masters Theses, 2010-2019

Riparian zones harbor an above average plant biodiversity. This biodiversity is threatened by invasive species and increasing human disturbance, the latter of which includes deforestation from agriculture and urban development. In this study, I examine relationship between the width of a forested riparian zone and the vegetation growing there. By using floristic quality assessment as a measure of anthropogenic disturbance, one can determine if wider riparian zones foster exclusion of non-native species while providing higher quality habitats for native plants. A randomized block design was used with three forested riparian treatments: deforested, moderately forested (woody vegetationstream), and extensively forested (woody …

Profile Of The Unfolded Protein Response In C. Elegans Depleted Of The Translational Chaperone, Nac., Caylin S. Murray

Masters Theses, 2010-2019

The function of a protein is a direct consequence of its final structure, which is achieved by protein-folding processes that generate a tertiary state through the juxtaposition of locally formed secondary structures. Because all cells need functional proteins to survive, each contains robust and redundant mechanisms that regulate the folding of newly forming proteins, and the refolding of misfolded proteins that are often generated during stress. Essential to these mechanisms, chaperones are proteins that aid in protein folding of nascent and misfolding protein without being incorporated in the final structure. One chaperone complex, the nascent polypeptide-associated complex (NAC), aids in …

Colloidal And Biological Properties Of Triscationic Amphiphiles With One Or Two Tails, John N. Marafino

Masters Theses, 2010-2019

The decline in the development of novel antimicrobials, combined with the misusage and over prescription of antibiotics, has contributed to the increasing prevalence of antimicrobial-resistant infections. Thus development of effective novel disinfectants could reduce the transmission of pathogens and decrease the risk of infection by antibiotic resistant organisms. The antimicrobial activity of amphiphiles, compounds with hydrophobic and hydrophilic regions, was first reported in 1935, and has influenced the synthesis of amphiphiles with variations in structure. In this study, three series of amphiphiles were synthesized by two subsequent Menshutkin reactions. Each amphiphile contains one or two hydrocarbon tails ranging from 8 …

Characterization Of Vibrio Vulnificus Strains Using Phenotypic And Genotypic Assays, James Conrad

Masters Theses, 2010-2019

In this study 143 V. vulnificus isolates of clinical and environmental origin, were examined for growth on differential media, identified to species and tested for antibiotic resistance. A multiplex PCR was created and optimized, and phylogenetic analysis was conducted. The first objective was to compare phenotypic methods to identify V. vulnificus. Colony colors of confirmed V. vulnificus isolates on selective media (Vibrio vulnificus agar, thiosulfate citrate bilesalts sucrose agar, CHROMAgar Vibrio (CAV), and colistin polymyxin B cellobiose agar), mostly matched those characteristic of V. vulnificus. To test the ability of these media to select for V. vulnificus, new presumptive V. …

Performance Quantification Of Extensive Green Roof Substrate Blend: Expanded Shale And Biochar, James Sheats

Masters Theses, 2010-2019

Urban stormwater management practices often involve the redirection of runoff to local waterbodies. As such, the quality of runoff directly affects the condition of these receiving waters. Green roofs offer many benefits to the urban environment including attractive aesthetics, thermal insulation for buildings and stormwater runoff reduction. Unfortunately, in order to promote the spread of vegetation, fertilization is often practiced that can lead to elevated nutrient concentrations in runoff and, ultimately, nearby streams, rivers and bays. Different amounts of biochar, pyrolyzed biomass, were added to model green roof trays to test for the ability of this charcoal-like substance to prevent …

An Analysis Of U.S./Canadian Fisheries Policy In Regards To Pacific Salmon And The Preservation Of Indigeneity In The Pacific Northwest, Michael James Lockwood

Masters Theses, 2010-2019

For more than 160 years, the Pacific salmon has been an important resource for the United States and Canada. However, it has been overexploited. Proper management of the species is essential not only for maintaining healthy populations but also maintaining the interests of diverse stakeholders. One set of stakeholders consists of the indigenous peoples of North America because the Pacific salmon are crucial to their food, social, and ceremonial traditions.

This thesis explores the impacts of Canadian and U.S. public policies on the cultural integrity of native peoples in the Pacific Northwest, specifically as those peoples rely on wild Pacific …

Polyculture Bioremediation: An Analysis Of Potential Nitrogen Assimilation And Removal By Mya Arenaria, Gracilaria Tikvahiae And Ulva Lactuca Harvests In The Corsica River, Md, Kathleen Hemeon

Masters Theses, 2010-2019

An analysis of nitrogen bioremediation in a tidal tributary of the Chesapeake Bay by the use of a hypothetical bivalve and macroalgae polyculture covering 1%, 3% and 5% of the Corsica River bottom area. This study was performed to illustrate the role ecosystem services play in managing diffuse watershed pollution, particularly nitrogen, resulting in water quality and living resource degradation. Excess concentrations of nitrogen in the Corsica River estuary lead to seasonal eutrophication and subsequent hypoxic events. Mya arenaria L. and Gracilaria tikvahiae (McLachlan, 1979) were chosen for this theoretical study due to their high assimilative capacities for nitrogen and …
