The Impact Of Sickle Cell Disease On Gingival Bleeding And Oral Health Of Adults, Natalie Roa
The Impact Of Sickle Cell Disease On Gingival Bleeding And Oral Health Of Adults, Natalie Roa
Honors Undergraduate Theses
Oral health may serve as an indicator of overall systemic health, with each disease or condition manifesting differently in the oral cavity. Sickle cell disease (SCD) is a genetic disorder in which sickled red blood cells cause blood vessel occlusion and potentially bleeding in specific sites (e.g., gastrointestinal and intracranial bleeding). With SCD being one of the most common hereditary diseases in the world, it is essential to understand the disease and improve awareness to better treat this population. While studies have been done to evaluate the oral health of persons with SCD, few have explored the occurrence of gingival …

Serotonin's Proliferative Effects On Lung Cancer Cell Lines, Jessy K. Ntabo
Serotonin's Proliferative Effects On Lung Cancer Cell Lines, Jessy K. Ntabo
Honors Undergraduate Theses
Serotonin has been widely explored in the brain. Recently, there have been new findings on how serotonin works in the periphery. Serotonin is introduced to the periphery by the enterochromaffin cells and metabolized by the liver and lung. Studies have shown that serotonin plays a role in controlling lung cancer. However, the mechanism by which it initiates tumor formation has not been fully explored. Cell viability was measured in several lung adenocarcinoma cell lines treated with serotonin to study this effect. In GFP-labelled cells, fluorescence intensity was measured for quantification of cell viability. Our data showed an overall increase in …

Assessing The Feasibility, Acceptability, Appropriateness, Barriers, And Facilitators To Implementing Naloxone Distribution In Residential Areas At Ucf, Isabella S. Arguello-Howe
Honors Undergraduate Theses
With the rise of accidental fentanyl overdoses and recreational opioid use in college-aged populations, the need for campus-based overdose prevention and harm reduction measures is at an all-time high. Naloxone, an opioid antagonist, is an FDA-approved, lifesaving, medication which can be intranasally delivered by laypersons. Naloxone reverses opioid overdose, essentially buying time until an overdosing individual receives emergency medical attention. While some previous studies have examined access to naloxone on college campuses, to my knowledge no study has explored distribution of naloxone in residential college areas, such as dormitories and within Greek housing. Therefore, the purpose of this thesis was …

A New Form Of Catfishing: An Analysis Of The Inauthentic Racial And Ethnic Self-Presentation On Social Media, Britney R. Raymond
A New Form Of Catfishing: An Analysis Of The Inauthentic Racial And Ethnic Self-Presentation On Social Media, Britney R. Raymond
Honors Undergraduate Theses
Trends in self-presentation in social media (i.e., Twitter and Instagram) constantly fluctuate as fads come and go, especially when one’s image is being commodified. Specifically, numerous instances of celebrities and social media influencers altering their images to fit popular online trends and “aesthetics” contribute to increased blackfishing, Asianfishing, and Hispanicfishing. Some celebrities and influencers accused of “-fishing” in the presentation of ethnicity include the Kardashians, Ariana Grande, Addison Rae, Iggy Azalea, Selena Gomez, and Gigi Hadid. The present study (N = 685) investigated gender, personality, fame appeal, self-esteem, and need to belong in relation to attitudes towards the “-fishing” culture. …
Associations Between Shame And Guilt, Self-Esteem, And Health Risk Behavior Among Undergraduate Students, Hanya Irfan
Associations Between Shame And Guilt, Self-Esteem, And Health Risk Behavior Among Undergraduate Students, Hanya Irfan
Honors Undergraduate Theses
Health Risk Behavior (HRB) is defined as behavior that increases the likelihood of adverse outcomes: injury, morbidity, or mortality. University students are particularly susceptible to HRB due to their age, academic pressures, social environment, and newly unsupervised lifestyle. Despite major efforts by university campaigns to make students aware of the potential health risks of HRB, students continue to consistently engage in behavior that risks both their short-term and long-term health. Previous literature indicates the importance of self-esteem in positive decision-making and the inhibiting role of shame in increasing withdrawal and social isolation. Shame and guilt are distinct self-conscious emotions often …
Effects Of Mental Health Disorders On Time Perception, Mirella S. Galliano-Rechani
Effects Of Mental Health Disorders On Time Perception, Mirella S. Galliano-Rechani
Honors Undergraduate Theses
Research suggests a relationship between time distortion and mental health disorders, and the present study sought to examine this proposition. Prior research suggests that negative emotions are associated with the slowing down of time. Because mental health disorder symptomology is associated with more negative emotions, it was predicted that negative emotions would mediate the relationship between mental health disorder symptomology and time distortion. A survey was administered to university students that contained measures of anxiety, depression, emotional experiences, and time perception. Mental health disorder symptomology was found to be related to negative emotions. However, negative emotions and mental health disorder …

Exploring The Relationship Between Nutrition And Cribra Orbitalia: The Comparison Of Dietary Stable Isotope Comparisons Of Juveniles From Kuelap, Peru, Lissette S. Osorio
Exploring The Relationship Between Nutrition And Cribra Orbitalia: The Comparison Of Dietary Stable Isotope Comparisons Of Juveniles From Kuelap, Peru, Lissette S. Osorio
Honors Undergraduate Theses
A juvenile’s dependency on their caregiver is significant to the overall development of nutritionally related pathological lesions. However, not all skeletal pathology is caused by nutritional stress; despite anemia being the usual inferred cause, the origin of Cribra Orbitalia (CO) – lesions on the orbital roofs of the cranium– is undetermined. The purpose of this research is to compare the reconstructed diets of juveniles with and without CO and explore connections to dietary patterns (inferred from stable isotope ratios of carbon and nitrogen). Rib bone samples of 79 juveniles with and without CO were sampled from the Kuelap archaeological site …

Mechanical Understanding And Optimization Of Template Guided Core Needle Biopsy, Isaac Girgis
Honors Undergraduate Theses
Prostate cancer is the second highest cause of cancer related deaths among men. According to the diagnostic pathway for prostate cancer, a prostate biopsy is performed if an individual showed signs of lesions through high prostate-specific antigen (PSA) concentration or suggestive digital rectal exam (DRE) results. The core biopsy mechanism involves inserting a beveled needle into the organ and removing a cylindrical fragment of tissue. Many factors affect the histological quality of the sample, including fragmentation, needle deflection, and needle insertion velocity. If a biopsy core is not clinically viable, an alternative core will need to be taken, resulting in …

Modeling And Simulation Of A Power Plant Boiler Including The Dynamics Of Swell And Shrink, Richard Perman
Electronic Theses and Dissertations, 2020-2023
Renewables such as photovoltaics and wind turbines have seen consistent growth in markets across the globe. While renewables increase grid capacity and reduce the use of fossil fuels, their generation rates fluctuate subject to external factors. As the ratio of renewables to nonrenewables increases, so does variability of net load on intermediate and peaking power plants. Power plants with heat recovery steam generators (HRSG) constitute a significant proportion in these categories. There are several interconnected systems within HRSGs, including drum boilers which exhibit interesting transient phenomena known as swell and shrink. Improved understanding, dynamic modeling, and real-time simulation (RTS) of …
Flame-Generated Turbulence For Flame Acceleration And Detonation Transition, Rachel Hytovick
Flame-Generated Turbulence For Flame Acceleration And Detonation Transition, Rachel Hytovick
Electronic Theses and Dissertations, 2020-2023
Detonations are a supersonic mode of combustion witnessed in a variety of applications, from next-generation propulsion devices to catastrophic explosions and the formation of supernovas. Detonations are typically initiated through the deflagration to detonation transition (DDT), a detailed process where a subsonic flame undergoes rapid acceleration increasing compressibility until a hotspot forms on the flame front inciting a detonation wave to form. Due to the complex nature of the phenomena, DDT is commonly investigated in three stages – (i) preconditioning, (ii) detonation onset, and (iii) wave propagation and stability. The research presented explores each of these stages individually, with a …

Although, most of the deployable propeller blades that have been designed in studies have the …
Experimental And Computational Heat Transfer Study Of Sco2 Single Jet Impingement, John Richardson
Experimental And Computational Heat Transfer Study Of Sco2 Single Jet Impingement, John Richardson
Electronic Theses and Dissertations, 2020-2023
The present study experimentally investigates the heat transfer capability of supercritical carbon dioxide (sCO2) single-jet impingement. The evaluated jet Reynolds number range is between 80,000 and 1,000,000, with a non-dimensional jet-to-target surface spacing of 2.8. CO2-impinging jet stagnation conditions were maintained at approximately 20 MPa and a temperature of 673 K for most experiments. The goal is to understand how changes in the aforementioned parameters influence heat transfer between the working fluid and the heated surface. Additionally, due to the elevated Reynolds numbers and difference in thermodynamic properties between air and CO2, air-derived impingement correlations may not be appropriate for …
