Investigation Of Dna Variability And Phylogenetic Relationships Of Perlesta (Plecoptera: Perlidae) In Mississippi, James C. Valentine, Mac H. Alford

Master's Theses

The genus Perlesta Banks, 1906 (Plecoptera: Perlidae) consists of 35 species, 33 native to the United States and Canada and two native to China. For over a century these small, brown stonefly adults and freckled yellow nymphs have gone by the name of the type species of the genus, Perlesta placida, but taxonomic work in the genus since 1989 has resulted in the recognition of additional species. These species were mostly recognized and described using morphological characteristics, but two areas that are lacking include (1) linking nymphs to adults and (2) phylogenetic analysis of all species occurring in Mississippi …

Induced Spawning Of Captive Tripletail Lobotes Surinamensis, Nicholas Adams

Master's Theses

The Tripletail, Lobotes surinamensis, is an emerging candidate species for U.S. marine aquaculture. This work aimed to address two bottlenecks for hatchery production of the species by developing a hormonal induction protocol to obtain fertile spawns from captive brooders and a method for sex identification of candidate brooders.

Single pairs selected among a captive-held broodstock conditioned under a natural photothermal cycle were induced with one of five treatments (n = 5 or 6 replicates per treatment). Control (no hormone) and hCG (1,100 IU.kg^-1 for females, 550 IU.kg^-1 for males) pairs did not spawn. Pairs treated with GnRHa …

Recovery From Minor Tropical Cyclones: The Response Of Faith-Based Organizations And Government Agencies To Minor Tropical Cyclones In Biloxi, Mississippi, Camilla Witherspoon

Master's Theses

The impacts of major hurricanes are extensively researched in Disaster Resilience literature and the field of Human Geography; in contrast, the aftermath of minor tropical cyclones is understudied. Along the Gulf Coast in 2020 and 2021, more minor tropical cyclones made landfall then major hurricanes (NOAA, 2021). Despite the frequency of minor tropical cyclones, few studies have considered the resources and actors involved in recovery from minor tropical cyclones.

This thesis uses qualitative methods, including semi-structured interviews and document collection, to examine how Faith-based Organization (FBO) and government agency leaders in Biloxi, Mississippi provide resources to residents, interact with each …

Bon Appѐtit: Faunal Subsistence At Fort Tombecbe (1su7)​, Sarah Coffey

Master's Theses

The frontier fort known as Tombecbe is situated on the Tombigbee River in present day Epes, Alabama. Tombecbe was constructed in 1736 as a staging point for Bienville’s campaign against the Chickasaw and to block encroachments by the British military. Following the Treaty of Paris, the fort was occupied successively by the British and then Spanish in the eighteenth century. Fortunately, historic documents and physical modifications to the fort suggest that it is possible to isolate and examine the French, British, and Spanish separately, however the breadth of the faunal analysis leaves this for future research. The soldiers at Tombecbe …

Experimental Investigation Of Material Flood Damage To Support Multi-Scale Flood Damage Prediction, Anna Katya Opel

Master's Theses

Current practice of flood loss prediction presents limitations in accurately predicting building flood losses at multiple scales. While whole-building estimates can more accurately predict high-level losses (i.e., large groups of buildings), a significant analysis error is revealed with small-scale (i.e., individual, or small groups of buildings) investigation. This research presents a robust, data driven, building damage model seeking to elucidate a more fundamental understanding of flood damage of material components commonly used in residential construction. The framework of the model is based on a component-level damage database composed of data collected from experimental analysis. Structures with standard residential construction materials …

Analytic Hierarchy Process Is Not A Suitable Method For The Comprehensive Rating, Sai Nethra Betgeri

Master's Theses

The Pipeline Assessment and Certification Program (PACP) was developed by the National Association of Sewer Service Companies, the industry-accepted protocol for condition rating of sewer pipes in the US. The PACP method relies exclusively on visual inspections performed using Closed-Circuit Television (CCTV), where existing structural and operation and maintenance (O&M) defects are observed by certified operators. A limitation of the PACP method is that it does not use pipe characteristics, depth, soil type, surface conditions, pipe criticality, and capacity, nor the distribution of structural defects or history of preventative maintenance to determine the condition rating of the sewer pipe segment. …

Exploring Ransomware On The Oculus Quest 2, Michael Mahan

Master's Theses

Virtual Reality Head Mounted Displays, also coined VR headsets, have breached barriers that held back widespread adoption and usage in the past. While covering the reasons for this large-scale spread, the idea is introduced that HMDs, which are standalone units, can become targets for malware. This work explores how applicable Android ransomware is to the Oculus Quest 2’s attack surface, due to the Quest’s usage of Android 10 as a base operating system. Existing ransomware samples are evaluated to determine an abstract definition of ransomware. This work also introduces SRS, Simple Ransomware Sample, which acts as a Proof-of-Concept, a minimum …

Analysis Of Selection Bias In Online Adversarial Aware Machine Learning Systems, Victor Barboza Morais

Master's Theses

As is evident in areas of privacy, security, and ethics, the hindrances to research is the lack of validated real-world data. Therefore, people resort to creating their own dataset and/or artificially increasing the size of existing datasets. However, in areas like countermeasures of phishing, this is not only insufficient but could introduce bias in the dataset in the process.

To raise the awareness of bias in Machine Learning (ML) / Artificial Intelligence (AI) and its consequences, this work tries to gauge one of its occurrences reliably, namely selection bias when generating more samples from existing samples in a dataset. However, …

How The Notch Signaling Pathway And Mediator Work Together To Regulate Hasc Self-Renewal, Taylor Teach

Master's Theses

Obesity is a serious medical condition resulting from excess body fat that triggers changes in both quantity and quality of various cells that reside in adipose tissue, including adipose stem cells. Adipose derived stem cells are multipotent, self-renewing cells that have the ability to differentiate. This process can be controlled by environmental stimuli, transcription factors, and signal cascades that lead to gene transcription and protein expression specific to the cell’s fate. The Mediator complex and the Notch signaling pathway are two complexes that allow this to occur. There is still much unknown about the Mediator complex, the Notch signaling pathways, …

A Research Framework And Initial Study Of Browser Security For The Visually Impaired, Elaine Lau, Zachary Peterson

Master's Theses

The growth of web-based malware and phishing attacks has catalyzed significant advances in the research and use of interstitial warning pages and modals by a browser prior to loading the content of a suspect site. These warnings commonly use visual cues to attract users' attention, including specialized iconography, color, and an absence of buttons to communicate the importance of the scenario. While the efficacy of visual techniques has improved safety for sighted users, these techniques are unsuitable for blind and visually impaired users. This is likely not due to a lack of interest or technical capability by browser manufactures, where …

'As Vivid As Blood In A Sink': (Re)Reading Queerness And Repression In Teju Cole's Open City, Jack Hoda

Master's Theses

Teju Cole’s Open City (2011) is an exemplar work of contemporary fiction. For its complex representation of subjectivity, hypnotic narrative tone, and global political scope, the novel has been praised by readers and critics alike. Julius, the text’s first-person narrator, guides us along seemingly innocent wanderings throughout New York City, ruminating on history, art, and politics while presenting himself as the enlightened, cosmopolitan ideal. However, the shocking penultimate revelation that Julius raped a young woman from his past alters our encounter with the text and its narrator. We come to realize that this meandering novel is, in reality, a carefully …

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed …

Master's Theses

Though the Great Depression and Second World War were consecutive eras and overlapped in numerous aspects, scholarship often overlooks the commonalities between these periods. To demonstrate these eras’ shared qualities, this thesis examines the relationship in emotional-cultures—the cultural norms that dictated how individuals felt and demonstrated their emotions—among Civilian Conservation Corps (CCC) enrollees and U.S. Army enlistees during WWII.

The broad intent of this undertaking is to place the cultural history of the Great Depression and WWII in conversation and to show the advantage of inter- and multidisciplinary work by applying anthropological and historical theories of emotion. Though the historical …

Sensitivity Of A Lamp Assay For Detection Of The Dinoflagellate Amyloodinium Ocellatum In Simulated Field Conditions And Freeze Tolerance Of The Parasite, Robert Gonzales

Master's Theses

The obligate parasitic dinoflagellate Amyloodinium ocellatum causes amyloodiniosis in warm water marine fishes. The prolific parasite, which has a direct, three-stage life cycle, is highly infectious and can cause heavy losses in aquaculture. Prevention, biosecurity, and early detection are vital for control. In this work, microscopy and a loop-mediated isothermal amplification (LAMP) assay were compared for early diagnosis of A. ocellatum in cultured stocks, and the freeze tolerance of tomonts was assessed to determine if frozen wild fish used as fish food can serve as a potential vector for the parasite.

The lowest dinospore concentration that could be detected by …

A Comparison Of Natural, Living, And Hardened Shorelines Ability To Prevent Coastal Erosion And Maintain A Healthy Ecosystem, Gabrielle Spellmann

Master's Theses

It is important to find a suitable method to protect the U.S. Gulf Coast shoreline, since its’ low elevation and the Loop current make it vulnerable to sea level rise. I focused on two manmade methods, hardened, and living shorelines, of coastal protection for when the natural marsh suffers excess erosion rates. Living shorelines are a suite of shoreline conservation and restoration techniques that usually involve some sort of hardened structure that dampens wave energy so that the native vegetation behind it can take root and stabilize the shoreline. This study looked at six different sites, all containing a natural, …

Acl Risk Data Comparison And Turnout Analysis Of Female Dancers Trained In Ballet And Female Traditional Jumping Sport Athletes, Samantha A. Campbell

Master's Theses

INTRODUCTION: An increase in participation in females sports has created an increase of female athletes at risk for injuring their Anterior Cruciate Ligament(ACL)[12,21,29,44]. Traditional jumping sports have the highest rate of non contact ACL injuries, due to the use of movements of cutting, pivoting and landing on one foot[5,8,32,33,38]. ACL injuries can also be attributed to neuromuscular deficits such as the ‘Ligament Dominance Theory’, ‘Quadricep Dominance Theory’, ‘Trunk Dominance Theory’ and the ‘Leg Dominance Theory’[24,33]. The neuromuscular deficits are muscle strength, power or activation patterns that can cause an individual to have an increased risk of ACL injury[33]. Female traditional …

Optimization Of A Novel Nipam-Based Thermoresponsive Copolymer For Intramuscular Injection As A Myoblast Delivery Vehicle To Combat Peripheral Artery Occlusive Disease, Quentin R. Klueter

Master's Theses

There is a need for a minimally invasive delivery method to enable cell therapies to combat peripheral artery occlusive disease (PAOD) in end stage patients. Myoblasts show promise as a cell mediated therapy but warrant an improved delivery method to increase cell retention in the region of interest because of their adherent nature, relative to previously used BM-MNC’s that are non-adherent. Contemporary issues with achieving successful cell therapies of vasculature can be mainly characterized by the lack of clinical translation from promising animal studies and absence of cell delivery scaffolding. Naturally, polymers have been widely experimented with as grafts to …

Impact Of Primary Myoblasts On Macrophage Polarization In-Vitro, Olivia Welch

Master's Theses

Peripheral artery disease (PAD) is characterized by the development of atherosclerotic plaques on arterial walls, leading to the narrowing of blood vessels, resulting in ischemia in the downstream tissue. In the United States, 12% of the adult population is affected by PAD and its related symptoms. Current surgical revascularization techniques can be effective in part of the patient population, but there is a need for other options. Alternatively, collateral blood vessels, or natural bypass arteries, enlarge to increase blood flow to the ischemic tissue in a process called arteriogenesis, which has been studied as a therapeutic option. Cell-based therapies, such …

System Performance Model And Control System For A Small-Scale Horizontal Axis Wind Turbine, Niko Banks

Master's Theses

Predicting the performance of wind turbines is a key part of the turbine design process and operation, as predictive models play a large role in determining potential power output and efficiency at different operating conditions to help maximize production. On small-scale wind turbines performance models become more complex, as the rotor aerodynamic performance depends not only on the tip speed ratio, but also on the flow Reynolds number. An accurate predictive model that includes this behavior on small-scale wind turbines can be used to find the optimal operating conditions for power output, and is also a critical component of the …

Evaluation Of Cost-Effective Alternative Designs For Rural Expressway Intersections, Jonathan Howard

Master's Theses

Despite numerous studies demonstrating the effectiveness of Restricted Crossing U-Turn (RCUT) intersection design, its implementation remains uneven and close to zero in some large states such as California. This research provides a comprehensive framework to estimate the operational and safety performance of future RCUT designs in California. The framework is demonstrated for five intersections located on high-speed rural expressways in California using VISSIM microsimulation models to measure operational performance for each intersection including the base condition with the existing Two-Way Stop-Controlled (TWSC) intersection and two RCUT designs. To evaluate future safety performance, the microsimulation models were further utilized to compile …
