The Effects Of Parathyroid Hormone And Bisphosphonate On The Cartilage And Subchondral Bone Of The Temporomandibular Joint, Alexandro De Araujo Lima Dec 2018

The Effects Of Parathyroid Hormone And Bisphosphonate On The Cartilage And Subchondral Bone Of The Temporomandibular Joint, Alexandro De Araujo Lima

Master's Theses

Introduction:Parathyroid hormone increases bone strength primarily by stimulating bone formation, whereas Bisphosphonate, an antiresorptive drug, reduce bone resorption by blocking osteoclast activity. Here we examined the effects of alendronate (ALN), a type of bisphosphonate, and we also examine the effects of parathyroid hormone (PTH), which has an anabolic effect and increases bone remodeling when treated intermittently (I-PTH). I-PTH treatment leads to increased bone volume fraction, tissue density and trabecular thickness of the subchondral bone. I-PTH treatment also increases proteoglycan synthesis with a concomitant increase in mineralization of the Mandibular Condyle Cartilage (MCC). We hypothesize that combined treatment of I-PTH …

Groundwater Model Parameter Estimation With Simultaneous And Sequential Use Of Hydraulic Head And Travel Time Measurements, Mohsen Kheirabadi Dec 2018

Groundwater Model Parameter Estimation With Simultaneous And Sequential Use Of Hydraulic Head And Travel Time Measurements, Mohsen Kheirabadi

Master's Theses

This study is an effort to investigate two parameter estimation approaches in groundwater modeling, sequential and combined. Most researches imply that simultaneous use of flow and transport observations would be more beneficial in parameter estimation, however some other researchers rise questions about this approach. They believe due to the differing geological properties of aquifers and consequently differing mathematical basis of groundwater flow compared to transport simultaneous use of different observations might not be useful in every cases. Despite the fact that parameter estimation or inverse modeling is not a new method in groundwater modeling, most modelers tend to use forward …


Shakespeare's Adaption Of Cinthio's "Un Capitano Moro" Into Othello, Cleveland A. Williams Dec 2018

Shakespeare's Adaption Of Cinthio's "Un Capitano Moro" Into Othello, Cleveland A. Williams

Master's Theses

Abstract

William Shakespeare’s Othello is an adaptation of Giovanni Battista Giraldi Cinthio’s “Un Capitano Moro,” that was written in 1565; taken from his novella collection ‘Gli Hecatommithi,’ Decad.III., Novella 7. Cinthio’s story of the Moor of Venice fits the classification of the Italian novellas which grew to prominence during the fifteenth and sixteenth centuries due to the popularity of Boccaccio’s Decameron.

Shakespeare liberated this story from its state of oblivion and utilized it as his framework for Othello; as the plot exposes some of the most intricate of human emotions – love, hate and jealousy, which are all …

Master's Theses

This MS thesis research has focused on the profiling feasibility of flat thin mm-sized soil moisture sensor (termed as MSMS) through field tests at UConn farm and Ethiopia farms. By etching on gold compact disc (CD), MSMS has the distinct merits of small size (mm-carbon interdigitated with 0.5 mm thickness), high accuracy of soil moisture measurement (10 kΩ-10 MΩ for 10%-50% soil moisture), good correlation of resistance readings with soil moisture, long stability (stable at least for half a year in lab tests) and easy fabrication (sensor), and low cost (


Tall Tales Of Danger And Security: How A Critical Human Security Approach Can Address Major Contradictions Revealed Through A Critical Narrative Analysis Of Dominant U.S. Security Strategies, Stephen Schneider Dec 2018

Tall Tales Of Danger And Security: How A Critical Human Security Approach Can Address Major Contradictions Revealed Through A Critical Narrative Analysis Of Dominant U.S. Security Strategies, Stephen Schneider

Master's Theses

Over many generations, humans have developed many perspectives and practices regarding the best ways to recognize and address what they perceive to be dangerous. Stories are used to help shape and narrate perceptions about the world, and they serve to pass on vital information that impacts how a society responds to threats and vulnerabilities. These narratives of danger and security are subjective to the experiences and political intentions of society, and therefore in many ways are partial and biased in their assessments and policies. This results in flawed security practices that may actually exacerbate threats or create new insecurities. What …

Looming Large: An Analysis And Evaluation On The Growth Of The Urban Informal Economy In Nigeria., Tamunotonye A. Sekibo Iii

Master's Theses

The Informal Economy looms large! The importance, magnitude and significance of the vast range of socio-economic activities taking place within and across diverse spaces of informality, particularly in nations situated in the Global South; can neither be overstated or underestimated. According to the International Labor Organization (ILO, 2018 p.v), approximately 60% of the world’s employed population - 2 billion people - obtain their source of income through their engagement in informal spaces.


Electropolymerization Of Polyaniline In The Presence Of Ferricyanide: Electrochemical, Spectroscopic And Gravimetric Studies, Lucas Marinelli Dec 2018

Electropolymerization Of Polyaniline In The Presence Of Ferricyanide: Electrochemical, Spectroscopic And Gravimetric Studies, Lucas Marinelli

Master's Theses

In this work, ferricyanide-doped polyaniline (PANI) is electropolymerized by constant current and cyclic voltammetry (CV) measurements with simultaneous monitoring of mass changes using electrochemical quartz crystal microbalance (eQCM). Raman spectroscopy, Fourier transform infrared spectroscopy and CV measurements confirm the incorporation of the ferricyanide into the film and indicate modified electrical conductivity. UV-Vis absorbance spectroscopy and Raman spectroscopy confirm the conducting ‘emeraldine-salt’ state and confirm the presence of polarons, i.e. charge carriers.

The addition of ferricyanide during electropolymerization of the PANI film results in an increase of polymerization rate as confirmed using eQCM. A decrease in counter ion ingress/egress and an …

Social Capital And Resilience In Times Of Disaster: A Case Of Leyte Province In The Philippines, Karmela Beatriz Galura

Master's Theses

Social capital and its elements such as trust, reciprocity, and collective action have always been linked to a community’s resilience during and after natural disasters. Using a qualitative approach, I explore the role social capital played in the recovery of communities in the province of Leyte in the Philippines after Typhoon Haiyan in 2013. I also examine whether trust was a key element in the role social capital played. Through surveys and interviews, I explore the ways in which trust and perceptions of it could be the materialization of certain values and practices in local Filipino culture which contributed to …


Engineering Yeast To Evaluate Human Proteins Involved In Selective Rna Packaging During Hiv Particle Production, Ryan M. Bitter Dec 2018

Engineering Yeast To Evaluate Human Proteins Involved In Selective Rna Packaging During Hiv Particle Production, Ryan M. Bitter

Master's Theses

Despite recent advances in antiretroviral therapy, nearly 37 million people continue to live with human immunodeficiency virus (HIV). Basic and applied research on the assembly of HIV could be enhanced by using a genetically tractable organism, such as yeast, rather than mammalian cells. While previous studies showed that expression of the HIV Gag polyprotein in Saccharomyces cerevisiae spheroplasts resulted in the production of virus-like particles (VLPs), many questions regarding the utility of yeast in HIV assembly remain uninvestigated. Here, we report use of S. cerevisiae for both the production of VLPs with selectively packaged RNA and to evaluate the human …


Presence Of Antibiotic Resistant Salmonella Spp. In Backyard Poultry And Their Environment, Nicole Land Dec 2018

Presence Of Antibiotic Resistant Salmonella Spp. In Backyard Poultry And Their Environment, Nicole Land

Master's Theses

As keeping backyard poultry rises, human contact with zoonotic pathogens will increase. One such pathogen that backyard enthusiasts have exposure risks to is Salmonella spp. which may cause a potential public health threat due to its increasing multidrug resistancy. Salmonella spp. were present in 33 of 50 samples collected from 29 sites with backyard poultry coops in San Luis Obispo County during March to May in 2014. Two different Hardy-CHROME™ Salmonella Selective Media plates were used to culture and isolate positive samples of Salmonella spp.. Each positive isolate was tested for antimicrobial sensitivity to 6 standard antibiotics: Ampicillin, Bacitracin, …


Assessing Risk In Iot Devices, David Levitsky Dec 2018

Assessing Risk In Iot Devices, David Levitsky

Master's Theses

The explosive growth of the Internet of Things ecosystem has thrust these devices into the center of our lives. Unfortunately, the desire to create these devices has been stronger than the one to secure them. Recent attacks have shown us ignoring security in Internet of Things devices can cause severe harm in both a digital and physical sense. This thesis outlines a framework for developers and managers to assess the risk of IoT devices using a weighted scoring system across five different categories. Our case studies suggest that devices with higher security considerations have a better security posture and lower …


Investigating The Effect Of An Upstream Spheroid On Tandem Hydrofoils, Joel Tynan Guerra Dec 2018

Investigating The Effect Of An Upstream Spheroid On Tandem Hydrofoils, Joel Tynan Guerra

Master's Theses

This thesis documents a series of three dimensional unsteady Reynolds Averaged Navier-Stokes CFD simulations used to investigate the influence of an upstream prolate spheroid body on tandem pitching hydrofoils. The model is validated by performing separate CFD simulations on the body and pitching hydrofoils and comparing results to existing experimental data. The simulations were run for a range of Strouhal numbers (0.2-0.5) and phase differences (0-π). Results were compared to identical simulations without an upstream body to determine how the body affects thrust generation and the unsteady flow field.

The combined time-averaged thrust increases with Strouhal number, and is highest …

Characterizing Ecological And Genetic Patterns Of The Colonizing Species Dubautia Scabra On The Big Island, Hawaii, Samantha Kaleigh Naibauer

Master's Theses

The Hawaiian Silversword Alliance (HSA) is a group of approximately 35 endemic species found on the Hawaiian Islands. The HSA is of particular interest due to the vast adaptive responses of its members across the Hawaiian Islands. Each of these plant species is generally limited to a very specific habitat type with a unique morphology and physiology. Dubautia scabra is the first angiosperm colonist of new lava flows, arriving in as few as two years after lava cools. The critical role D. scabra plays in this ecosystem gives a unique starting point for understanding downstream ecological processes such as seed …


An Investigation Of Enzymes Capable Of Activating Cannabinoid Prodrugs, Brittney J. Morgan Dec 2018

An Investigation Of Enzymes Capable Of Activating Cannabinoid Prodrugs, Brittney J. Morgan

Master's Theses

The plant Cannabis sativa contains a class of terpenophenols called cannabinoids which, in their active form, have been shown to have antiproliferative, anti-metastatic, anti-angiogenic, and pro-apoptotic effects on several types of cancer cells both in vitro and in vivo. Cannabinoids have been shown to not exert this apoptotic activity in healthy cells and they do not elicit the usual side effects seen with conventional chemotherapies. However, naturally occurring prodrugs from Cannabis must first be converted into the active form to induce the apoptotic and other physiological activities. Although humans do not possess the enzyme(s) necessary for this conversion, several different …

Ecological Stoichiometry: What Role Does It Play In The Competition And Spatial Distribution Patterns Of Aedes Albopictus And Aedes Aegypti?, James Deerman Dec 2018

Ecological Stoichiometry: What Role Does It Play In The Competition And Spatial Distribution Patterns Of Aedes Albopictus And Aedes Aegypti?, James Deerman

Master's Theses

Ecological stoichiometry is the balance of chemical substances within animal bodies through interactions and processes within their ecosystem. Though relatively underexplored, it provides a wealth of information linking interactions across different levels of organization. Detritus is the base of the food web within the small aquatic ecosystems occupied by the mosquitoes Aedes albopictus and Aedes aegypti. Nutrient content of detritus varies, but it can have a negative effect on mosquito growth and survival if nutrient thresholds are not met. I investigated nutrient environments and species abundance in cemetery vases in New Orleans, LA to assess detrital heterogeneity and its …


Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor Dec 2018

Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor

Master's Theses

Contact with the pectoral fin facilitates formation and maintenance of social relationships between dolphins (Dudzinski & Ribic, 2017). Additionally, several studies have shown that bottlenose dolphins have distinct personalities that are consistent across time and situation (e.g., Highfill & Kuczaj, 2007; Kuczaj, Highfill, & Byerly, 2012), and it has been suggested that these individual differences (i.e., personality) may influence tactile behavior exchanges. The current study therefore aimed to determine if bottlenose dolphin personality traits predict whether and how dolphins initiate contact as a rubber or rubbee during pectoral fin contact exchanges, and to identify whether the effects of personality traits …


The Return Of The Dead: Resurrecting Chappell's Family Gathering, Jonathan Moore Dec 2018

The Return Of The Dead: Resurrecting Chappell's Family Gathering, Jonathan Moore

Master's Theses

This thesis examines Fred Chappell’s virtually overlooked collection of poetry Family Gathering (2000), and how the poems operate within the mode of the grotesque. I argue that the poems illuminate both the southern grotesque and Roland Barthes’s theory of photography’s Operator, Spectator, and Spectrum. I address Family Gathering as a family photo album full of still shots, snapshots, and even selfies, which illumines how Chappell’s use of the grotesque in this collection derives more from its original association with visual arts rather than only depicting the grotesque typically associated with characteristics deemed explicitly shocking or terrifying. I argue that …


Freshwater Invertebrate Assimilation Nutrients From Detrital Biofilms Under Light And Phosphorus Manipulation, Taylor Price Dec 2018

Freshwater Invertebrate Assimilation Nutrients From Detrital Biofilms Under Light And Phosphorus Manipulation, Taylor Price

Master's Theses

Anthropogenic influences are increasing algal biomass and activity within aquatic ecosystems, stimulating debate regarding interactions between “green” and “brown” food webs. Specifically, in forested streams, the removal of forest canopy or riparian zones increases light exposure and nutrient fluxes to streams affecting primary productivity and carbon (C) flows across aquatic food webs. Further understanding the synergistic effects of light and nutrients on detrital biofilms may explain how aquatic detritivores respond to anthropogenic change. The objective of this study was to employ C and phosphorus (P) isotopic radiolabels to understand how microbial biofilm constituents (i.e heterotroph and autotroph) contribute C and …


A Computational Analysis Of The Gradient Concentration Profile Of Deet And The Mosquito Behavioral Response, Brandon Carver Dec 2018

A Computational Analysis Of The Gradient Concentration Profile Of Deet And The Mosquito Behavioral Response, Brandon Carver

Master's Theses

DEET is a common active ingredient in most spatial repellents. DEET is also a volatile organic compound. DEET prevents mosquitoes from detecting and coming into contact with an human individual. Gas sensing technologies such as metal oxide semiconductor sensors can detect VOCs. The World Health Organization provides the majority of efficacy testing methods. This research adapts methods from the WHO and use of MOS sensors to further understand how and why DEET affects mosquitos. A custom developed system is used to measure DEET dissipation and observe mosquito behavioral response to the DEET. DEET dissipations and mosquito behavior is measured within …

Venom Composition Of Little Known Mountain Rattlesnakes And Predator-Prey Interactions Of Crotalus Pricei Pricei And Its Natural Prey, Sceloporus Jarrovii, Emily Grabowsky

Master's Theses

The Crotalus intermedius clade is a small group composed of four species: C. intermedius, C. transversus, C. pricei, and the recently identified C. tancitarensis (Alvarado-Díaz and Campbell, 2004; Reyes-Valesco et al. 2013). Though these species are restricted to high elevations of Sky Islands of southern Arizona and throughout México, little has been reported about their natural history and basic biology, including venom composition. Specifically, the Western Twin-spotted Rattlesnake (C. pricei pricei) is a small lizard specialist restricted to the more northern Sky Islands of México, with isolated populations in southern Arizona, where they are a protected species. …


Amplifying The Prediction Of Team Performance Through Swarm Intelligence And Machine Learning, Erick Michael Harris Dec 2018

Amplifying The Prediction Of Team Performance Through Swarm Intelligence And Machine Learning, Erick Michael Harris

Master's Theses

Modern companies are increasingly relying on groups of individuals to reach organizational goals and objectives, however many organizations struggle to cultivate optimal teams that can maximize performance. Fortunately, existing research has established that group personality composition (GPC), across five dimensions of personality, is a promising indicator of team effectiveness. Additionally, recent advances in technology have enabled groups of humans to form real-time, closed-loop systems that are modeled after natural swarms, like flocks of birds and colonies of bees. These Artificial Swarm Intelligences (ASI) have been shown to amplify performance in a wide range of tasks, from forecasting financial markets to …


Art As Invitation: The Effects Of Including Art Education In The Curriculum Of A Preschool Classroom Of Refugee Students, Nancy Heckmann Erekson Dec 2018

Art As Invitation: The Effects Of Including Art Education In The Curriculum Of A Preschool Classroom Of Refugee Students, Nancy Heckmann Erekson

Master's Theses

This study is about how art constitutes an invitation for marginalized people. Refugees are the uninvited, and often remain on the periphery of host communities. This research examines how artmaking acts as an invitation for refugee preschool students and their families to connect with the broader community. I approached data collection through the method of educational connoisseurship and educational criticism and the theory of relational aesthetics. I analyzed data from observations conducted in a refugee preschool classroom and from interviews with six families. Further, I analyzed observations and surveys from a public exhibit of children’s art. These sources provided data …

Vitality Of Water/Vitalidad Del Agua: Our Sacred Connection To Water And How We Can Interpret The Importance Of Water Through Artistic Inquiry, Jenifer Fogarty

Master's Theses

Water has appeared in the work and study of artists for centuries. There are countless aspects of water to be explored, from the sheer physical qualities of water to the spiritual, political, and practical associations with water. Water is what gives us life, and yet the vitality of this precious resource has been threatened over time. This exploration highlights important aspects of the study of water through art-making. My exploration began in the studio while making my own work. I sought to create a multi-sensory environment where viewers could participate and be immersed in the work itself. The site-specific installation …


Investigating Possible Scurvy In The Postclassic Maya Of Tipu, Emmalea Gomberg Dec 2018

Investigating Possible Scurvy In The Postclassic Maya Of Tipu, Emmalea Gomberg

Master's Theses

Although residing in a tropical environment, numerous researchers have posited the possibility of scurvy in the Maya in recent years. The historic population of Tipu in western Belize dating to AD 1541-1638 is one of the largest and best preserved Maya series, and was therefore evaluated for possible presence of scurvy since the diet appears typical of the pre-contact Petén populations. The temporal bones and greater wings of the sphenoid were analyzed for scorbutic activity in 143 individuals, along with periodontal disease and antemortem tooth loss to determine if there was a co-occurrence with scurvy.

Overall, 27% of the sample …


Pseudomonas/Brachypodium As A Model System For Studying Rhizosphere Plant Microbe Interactions Under Water Stress, Janiece Mcwilliams Dec 2018

Pseudomonas/Brachypodium As A Model System For Studying Rhizosphere Plant Microbe Interactions Under Water Stress, Janiece Mcwilliams

Master's Theses

In contrast to well-studied mechanisms of drought tolerance in plants, the interactions between plants and their microbiome during water stress are still poorly understood. This missing knowledge is crucial for the exploitation of beneficial microbial communities to improve the sustainability of agriculture under changing climatic conditions. The research described here bridged this gap by focusing on the molecular interactions between beneficial rhizobacterium Pseudomonas synxantha 2-79 and annual grass Brachypodium distachyon Bd21. 2-79 exemplifies a group of rhizobacteria associated with dryland wheat, while B. distachyon originates from the Middle East and has emerged as a model for valuable biomass, food, forage, …


Cold Acclimation Response Of Non-Native Italian Wall Lizard (Podarcis Siculus) Populations From New York And California, Daniel Haro Dec 2018

Cold Acclimation Response Of Non-Native Italian Wall Lizard (Podarcis Siculus) Populations From New York And California, Daniel Haro

Master's Theses

Understanding how organisms respond to climatic variability and novel conditions is becoming an increasingly important task for ecologists. For ectotherms in the northern hemisphere, the response to cold is of special interest, considering that poleward range expansion events and increasing variability of temperatures during winter are already being observed as consequences of a warming planet. Though direction of change in physiological variables in response to cold is well studied in ectotherms, the extent to which traits can change and the rate at which they can change is not.

We compared the extent and rate of change in cold tolerance (CT …


Cleaver: Classification Of Everyday Activities Via Ensemble Recognizers, Samantha Hsu Dec 2018

Cleaver: Classification Of Everyday Activities Via Ensemble Recognizers, Samantha Hsu

Master's Theses

Physical activity can have immediate and long-term benefits on health and reduce the risk for chronic diseases. Valid measures of physical activity are needed in order to improve our understanding of the exact relationship between physical activity and health. Activity monitors have become a standard for measuring physical activity; accelerometers in particular are widely used in research and consumer products because they are objective, inexpensive, and practical. Previous studies have experimented with different monitor placements and classification methods. However, the majority of these methods were developed using data collected in controlled, laboratory-based settings, which is not reliably representative of real …
