Building And Characterizing A Lab-Scaled Aquifer Storage And Recovery System, Murat Can Kayabas

USF Tampa Graduate Theses and Dissertations

To use Aquifer Storage and Recovery (ASR) as a water treatment and storage method, we must understand the fate and behavior of potential contaminants in the system. Knowing more about the aquifer properties such as dispersivity will enable us to assess how the target chemicals behave in the system. Characterizing the aquifer by using a tracer is a good way to estimate dispersivity since the tracer is not adsorbed or degraded. This study aims to build a lab-scale physical model of a confined aquifer to simulate an ASR system, verify its hydraulic functionality, and characterize the hydraulics of the aquifer …

Consumerism And Pride: The Fate Of Paris’ Marais “Gayborhood”, Christina M. Csensich

USF Tampa Graduate Theses and Dissertations

In the 1980s the Marais neighborhood in Paris, France, became a haven for queer people, specifically gay, white men, filled with queer-owned and queer-centric businesses. By the year 2020, however, these businesses had been priced out by name-brand international corporations. In the 1990s, French television commercials and programs would not speak the word ‘homosexual,’ even when a character was openly queer. By the 2010s, companies regularly featured queer people and gay pride imagery and slogans in their advertising. The queer community in Paris has a unique relationship with the consumer economy, one that ties aspects of queer identity directly to …

Passive Nitrifying Biofilters For Onsite Treatment Of Saline Domestic Wastewater, Daniel Arnulfo Delgado

USF Tampa Graduate Theses and Dissertations

The infrastructure to support the growing world population has polluted many water bodies with nitrogen from urban and agricultural runoff and failing wastewater systems, such as improperly sited and maintained septic systems. Septic systems present a low energy and maintenance option to treat domestic wastewater and is a treatment option that can be done far from a centralized grid. This further reduces cost, maintenance, and energy as it reduces the need to build and maintaining sewage piping and the infrastructure to move the water longer distances. However, these systems tend to fail when their upkeep is left to homeowners that …

The Influence Of Maternal Body-Shaming Comments And Bodily Shame On Portion Size, Savannah R. Flak

USF Tampa Graduate Theses and Dissertations

Young adult women are more likely to be dissatisfied with their bodies (Wansink et al., 2017) and engage in disordered eating patterns when they have a history of receiving parental comments about their bodies during childhood (Fortesa & Ajete, 2014). Furthermore, high bodily shame mediates the relationship between receiving critical messages about eating from parents during childhood and disordered eating behaviors for young adult women (Oliveira et al., 2019). Altogether, this suggests that bodily shame is a distinct pathway linking parental influence during adolescence to eating disturbances. However, little research has examined the unique roles that bodily shame, internalized weight …

Bait-And-Kill: Targeting A Novel Heme Biochemical Pathway In Hundreds Of Cancers, Christopher G. Marinescu

USF Tampa Graduate Theses and Dissertations

Cancer cells are characterized by their ability to grow and proliferate in rates that far exceed normal cells by modifying their iron/heme metabolisms to levels higher than normal. This imbalance of heme biosynthesis can lead to cancer cells having a flux of heme intermediates to the point where they enter a state called heme-overdrive. Heme-overdrive is a process unique to a variety of cancers but absent in normal tissues. With this enhanced production, heme can act as an epigenic regulator for signaling proliferation (18). Through the novel strategy called ‘bait-and-kill,’ cancer cells will be coerced into a state of heme …

Promoting Hpv Vaccination With Vaccine-Hesitant Parents Using Social Media: A Formative Research Mixed-Method Study, Silvia Sommariva

USF Tampa Graduate Theses and Dissertations

Vaccine hesitancy, the refusal or delay in complying with set immunization schedules, has been proclaimed one of the “ten threats to global health” by the World Health Organization in 2019. Since then, the COVID-19 pandemic has reinforced the importance of vaccine promotion and management of vaccine hesitancy. While anti-vaccine arguments have not surprisingly evolved much over the past decades, the speed at which those ideas spread has. Web-based technologies, such as social network sites (SNSs), provide a fertile ground for vaccine-related misinformation to spread. Therefore, SNSs are a primary channel to scale efforts to address vaccine hesitancy, using customized approaches. …

Drug Candidates Targeting Hsp90/Cdc37 For The Treatment Of Neurodegenerative Disease, Ryan Martin

USF Tampa Graduate Theses and Dissertations

Neurodegenerative disease refers to the death of specific populations of neurons that canresult in dementia, loss of voluntary muscle motility, and other abnormalities. Two major neurodegenerative diseases are Alzheimer’s disease (AD) and Parkinson’s disease (PD), which are linked to abnormalities in Tau and a-synuclein proteins, respectively. Currently, there is no cure for these diseases. Our group and others have shown that chaperone proteins play a critical role in the processing of Tau and a-synuclein. The inhibition of the Hsp90/Cdc37 chaperone complex is shown to affect the levels of these two proteins. Hence, we hypothesized that a drug molecule, conglobatin (Cb), …

Young Adolescents’ Opportunity To Develop Concept Images Of Polygons In Middle School Mathematics Textbooks, Megan N. Cannon

USF Tampa Graduate Theses and Dissertations

Young adolescents build notions of figures through experiences. When young adolescentsbegin middle school mathematics, they already have prior assumptions and conceptualizations about shapes (Herbst, Fujita, Halverscheid, & Weiss, 2017). Over years of experiences, interactions, and exposures with a particular concept, these students develop concept images consisting of all the visual information, pictures, mental images, or properties associated with the particular mathematical concept (Vinner, 1983). Seminal works in the field of mathematics education research found that without an opportunity to engage with varied representations, young adolescent students may not develop robust concept images (Aspinwall, Shaw & Presmeg, 1997; Hasegawa, 1997; Mesa, …

Does Time-Weighted Averaging For Wbgt And Metabolic Rate Work For Work-Recovery Cycles?, John W. Flach

USF Tampa Graduate Theses and Dissertations

Heat stress affects thousands of works annually by causing heat-related illnesses. Wet bulb globe temperature (WBGT) is a widely accepted metric to assess the environmental contributions to heat stress. WBGT-based occupational exposure limits (OELs) include the ACGIH TLVs and the NIOSH RELs. The OEL threshold is adjusted downward with increasing metabolic rate. Further, there is an OEL for acclimatized and non-acclimatized workers. An often-recommended intervention found within a heat stress management program is work-recovery cycles to manage exposure. To prescribe work-recovery cycles, the common practice is to use time-weighted averaging (TWA) for the WBGT and the metabolic rate. The purpose …
