The Effects Of Microfluidization And Homogenization On The Composition And Structure Of Liposomal Aggregates From Whey Buttermilk And Commercial Buttermilk, Tracey Mai T. Nguyen

Master's Theses

Milk derived ingredients from the production of cheese and butter can be used as vehicles for nutrients. Buttermilk is a nutritious product of milk that comes from the churning of cream into butter. One of the advantages of buttermilk is that it is enriched in milk fat globule components, such as phospholipids and forms emulsions with fat when treated with high shear. The objective of this work was to explore the effects of shear on regular buttermilk and whey buttermilk in terms of liposomal aggregate size and chemical composition. The effects of microfluidization at 2000 psi and homogenization at 2000 …

The Design And Fabrication Of An Electrostatically Actuated Diaphragm With A Silicon-On-Insulator Wafer, Elizabeth L. Brooks

Master's Theses

Electrostatically actuated silicon membranes were designed, modeled, fabricated, and characterized. The intended application was for use in a microspeaker. Fabrication issues necessitated the use of thick diaphragms with a large gap between the electrodes. The devices did not function as speakers but did show actuation with a high DC voltage. Device dimensions were chosen by examining membrane mechanics, testing the processing steps required for device fabrication, and modeling with COMSOL. Several adhesives were researched to fabricate the device sidewalls, including BCB, PMMA, and TRA-Bond F112. A method for patterning PMMA through photolithography was found using a scanning electron microscope. Masks …

Analysis Of Post-Cranial Traits For The Assessment Of Biological Distance Among Temporally Distinct New World Populations Of African Descent, Claire Marie Dansereau

Master's Theses

This investigation examines change in post-cranial osteometric markers in temporally distinct New World populations of African ancestry: Newton Plantation series (17th-19th century Barbados; N = 16); two subsamples from the Hamann-Todd (HT) series (U.S.) based on birth year, 1865-1900 (N = 66) and 1901-1915 (N = 62); and the Forensic Databank Collection (FDB) (20th century U.S.; N = 137). It was anticipated that individuals from Newton would exhibit less admixture than those from H-T or FDB. They were also predicted to demonstrate greater skeletal robusticity due to mechanical loading. Additionally, it was expected that stature would increase over time due …

Comparative Analysis Of Antiviral Responses In Mouse Embryonic Stem Cells And In Mesenchymal Stem Cells, Jundi Wang

Master's Theses

Embryonic stem cells (ESCs) are cells that have unlimited capacity for selfrenewal and differentiation. These properties make ESCs a great cell source for application in regenerative medicine. When used for cell therapy, ESC-derived cells could be placed in a wounded area that is likely to be exposed to various pathogens. However, it is not well-understood whether ESCs and ESC-derived cells have active antiviral responses against infectious agents from the environment. To answer this important question, I comparatively analyzed the antiviral responses of ESCs and mesenchymal stem cells (MSCs, C3H10Tl/2 cell line) to infectious agents. Using the expression of type I …

Characterizing The Persistence Of Sewage Enterococci In Mississippi Coastal Waters, Kimberly Anne-Marie Lewis

Master's Theses

Enterococci are microbiological indicators of marine recreation water quality.
Their reliability as fecal indicators is questioned as they are shown to persist in the environment. Multiple laboratory studies on their persistence have been done but few under natural environmental conditions. The purpose of this study was to investigate how long sewage enterococci and enterococcal DNA persist in beach water and to determine whether there is a difference in the genetic diversity and hardiness of sewage vs. environmental isolates. To study persistence, sewage was diluted with beach water, placed in microcosms, and deployed at a beach site in Longbeach and Pass …

Madness, Scalawagery, And Reconstruction: Dr. William M. Compton And Civil War Era Politics, Eugene Allan Branstiter

Master's Theses

This thesis seeks to advance scholars' understanding of Civil War era Mississippi through an examination of the often overlooked role former Whigs and scalawags played in the state's postwar politics. Using the Mississippi State Lunatic Asylum and the career of its scalawag superintendent Dr. William M. Compton as lenses, this paper examines Civil War era Mississippi's political, social, and cultural history. In doing so, this thesis seeks to complicate the historical memory of the era—a memory often dominated by images of irreconcilable Redeemer Klansmen and Radical Republicans—by arguing that moderate white Mississippians played a powerful role in rebuilding their society …

Molecular Detection Of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds And Ruminants, Nabanita Mukherjee

Master's Theses

Ticks are hematophagous arthropods and capable of inoculating various infectious agents to their vertebrate hosts. Ticks attached to birds and ruminants are capable of carrying tick-transmitted microorganisms. In our study, the prevalence of tick-borne pathogens was examined in ticks infesting migratory songbirds and Pakistani ruminants. During spring migration seasons, ticks were removed from northward-migrating songbirds in Louisiana and identified as Amblyomma Jongirostre, Amblyomma nodosum, Amb/yomma ca/caratum, Amblyomma maculatum, and Haemaphysalis species, all are considered as Neotropical ticks. Ticks removed from ruminants were identified as Hya/omma anatolicum, Hyalomma dromedarii, Rhipicephalus microplus, and Rhipicephalus sanguineus. A total of 112 and 72 bacterial …

Adolescent Narcissism And Prosocial Behavior As A Function Of Peer, Parent, And Self-Perception, Rebecca Lynn Kauten

Master's Theses

The association between narcissism and aggression has been empirically supported in adults and adolescents, but it is unclear whether narcissism might also be related to prosocial behavior. The current study aimed to investigate different facets of narcissism in adolescents and their association with self-, parent-, and peer-reported prosocial behavior. In a sample of 175 at-risk adolescents ages 16-18 (151 males, 24 females), it was expected that reports of the individual's engagement in prosocial behavior would vary as a function of the informant and the specific facet of narcissism (i.e., adaptive or pathological). However, no main effects or interactions emerged with …

Development Of A Genetic Monitoring Program For Stock Enhancement Of Mississippi Spotted Seatrout (Cynoscion Nebulosus), Carly Renee Somerset

Master's Theses

The spotted seatrout is a coastal sciaenid fish that is intensively exploited in the northcentral Gulf of Mexico. A stock enhancement research program was initiated in 2004 to develop methods to culture juveniles and release them in natural habitats to increase recruitment in the fishery. The goal of this study was to initiate a genetic monitoring program for stock enhancement activities. Assays for 15 microsatellite loci were optimized. Simulations indicated that this panel of molecular markers was sufficient to identify recaptured hatchery fish with high confidence assuming genetic data on broodfish spawned to produce released fish were available. Stock structure …

An Insight Into The Microbial Diversity And Expression Of Cysteine Protease Inhibitors (Cystatin) In Rickettsia Parkeri Infected Amblyomma Maculatum, Khemraj Budachetri

Master's Theses

Amblyomma maculatum (Gulf Coast tick) is an emerging tick species of public health significance in United States. It is a competent vector of Rickettsia parkeri, an etiological agent of a human rickettsiosis. In this study, we investigated the spotted fever group of rickettsial diversity in A. maculatum based on rickettsial ompA gene PCR. Our results showed A. maculatum harbors R. parkeri, R. amblyommii, and R. endosymbiont of A. maculatum. While only R. parkeri was detected in female salivary glands which suggest its ability to traffic from midgut to salivary glands via hemocoel. The presence of R. parkeri was further …

Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera

Master's Theses

The efficient delivery of potable water for a community through its distribution system has historically been the backbone of nearly all metropolitan developments. Much of these systems are comprised of pipe networks made of various materials including concrete, iron, PVC, and even steel. As these communities expand and urbanize, water demand and population density simultaneously increase. This develops higher strains and stresses in the community‟s water distribution network causing pipes to corrode, crack, or rupture prematurely while in service. As a result, the deterioration of water distribution systems in growing cities is increasingly becoming a major concern for our nation. …

The Effects Of Variation In Collagen D-Spacing On Compact Bone Viscoelasticity: A Finite Element Analysis, Miguel A. Mendoza

Master's Theses

The D-spacing that is characteristic of collagen and its structural arrangement was previously thought to be a constant value. Much research is revealing that it is actually a distribution of values in biological tissues. Recent ovine experimentation has also shown that the D-spacing distribution is significantly altered following estrogen depletion. While ewes contain some major biological differences between their human counterparts, they are an economical and robust large animal model for postmenopausal osteoporosis. So, the exploration of the possible implications that D-spacing has on the mechanical properties of the whole bone utilizing animal models and computational methods is warranted. Six …

The Effect Of Social Networking On Grief, Heather Margaret Gianatassio

Master's Theses

Death and loss are complicated issues. They are further complicated by the Internet and the increased usage of social media; however, there is little research on the effects of social media on grief. This project's goal was to gather information about grieving via online social networking sites. Data was collected from 20 in memoriam profile webpages on Facebook and MySpace. The deceased were between the ages of six months and 32 years. Results indicate that society is using social media as a form of support and comfort in times of loss.

Sandcastles In The Sand: Liminality At The Seashore In Carolyn Wells's Marjorie At Seacote, Olivia Jeanne Bushardt

Master's Theses

The American beach at the turn of the twentieth century became a popular site for middle-class families to escape the urban squalor of the cities and play during the summer months. Although relatively unknown today, Carolyn Wells's 1912 novel Marjorie at Seacote depicts how the beach as a liminal space destabilizes the traditional adult and child roles and creates discomfon and ambivalence over these new roles. I first discuss Carolyn Wells and Marjorie at Seacote in terms of historical context and within the framework of girls' series fiction published at the turn of the century. I then explain how the …

Genetic Determinants Of Habitual Physical Activity And Overweight And Obesity, Harold Lee

Master's Theses

We tested 6 single nucleotide polymorphisms (SNPs) associated with obesity from genome wide association studies for their association with physical activity (PA). Healthy European-American women (n=265) and men (n=230) (23.5±0.3yr, 24.6±0.2kg•m^-2) were genotyped for MC4R (rs17782313), FTO (rs9939609), TMEM18 (rs6548238), NEGR1 (rs2815752), SH2B1 (rs7498665), and KCTD15 (rs11084753), and completed the Paffenbarger PA Questionnaire. We examined gene interactions by summing the number of obesity effect alleles. RESULTS: Normal weight subjects with MC4R T expended 1981.2±741.7kcal∙wk^-1 less than non-carriers in total PA (p=0.008), 1825.9±650.2 kcal∙wk^-1 less in sports/recreation (p=0.027), and 1231.3±552.7 kcal∙wk^-1 less …

The Effects Of A Model Androgen 5a-Dihydrotestosterone On Mummichog (Fundulus Heteroclitus) Reproduction Under Different Salinities, Chelsea O'Connor Blatchley

Master's Theses

Abstract

Endocrine disrupting substances (EDSs) have the potential to disrupt sensitive hormone pathways, including those involved in development and reproduction. Both fresh and estuarine water bodies receive inputs of EDSs from a variety of sources, including sewage effluent, industrial effluent, and agricultural runoff. Based on limited available literature, freshwater species appear to respond to lower levels of EDSs than estuarine or marine species. To address this potential difference, a short-term reproductive bioassay was carried out under low and high salinity conditions using mummichog (Fundulus heteroclitus), a euryhaline species that is native to the east coast of North America. …

Metamaterial Enhanced Wireless Power Transmission System, Travis Jade Heffernan

Master's Theses

Nikolai Tesla's revolutionary experiments demonstrated the possible benefits of transmitting power wirelessly as early as 1891. Applications for the military, consumers, emergency personnel, remote sensors, and others use Tesla’s discovery of wireless power. Wireless power transmission (WPT) has the potential to be a common source of consumable energy, but it will only receive serious consideration if the transmit and receive systems are extremely efficient and capable of delivering usable amounts of power. Research has been conducted to improve the efficiency and performance of nearly every aspect of WPT systems, but the relatively new field of metamaterials (MTMs) has yet to …

Evaluation Of Post-Residency Treatment Protocol Changes: A Web-Based Survey, John B. Gilbreth

Master's Theses

Clinical decision making in dentistry is multifactorial. Few studies have evaluated the influence of residency training on clinical treatment practices in dentistry. This study sought to explore the impact of resident training on post-graduate clinical protocol and the practitioner's rationale when making these decisions. Following IRB approval, a survey of 87 graduates from the Division of Endodontology at the University of Connecticut Health Center from 1978 to 2012 was administered. The method of temporization following nonsurgical endodontic therapy, dilution of sodium hypochlorite, instrumentation, treatment planning and endodontic sealer choice were evaluated and compared to the respondent’s residency training.

Surgical Tooling Designed For The Direct Anterior Approach To Total Hip Arthroplasty, Jon-Peter Meckel

Master's Theses

Surgical Tooling Designed for the Direct Anterior Approach to Total Hip Arthroplasty Jon-Peter Meckel

Total hip arthroplasty (THA) is becoming more and more common in the US as people continue to live longer and more active lives. The main reason that a THA is required is due to the “wear and tear” affliction of osteoarthritis, which in the year 2000 had at least 3% of the population over 30 showing symptoms. A revitalized approach to THA is the direct anterior approach, or Smith-Petersen approach, which limits the amount of musculature affected by the surgery and creates a very stable joint …
