Expansion Of The Performance Capabilities Of The Usf Inhalation Challenge Chamber, Laura Riley
Expansion Of The Performance Capabilities Of The Usf Inhalation Challenge Chamber, Laura Riley
USF Tampa Graduate Theses and Dissertations
The purpose of this research was to evaluate the capability and performance of the University of South Florida’s (USF) Human Exposure Chamber (HEC) using aerosols in the thoracic range. The goals of this research were two-fold: to obtain an average particle size of 10 µm (thoracic-size range) inside the chamber during dust production and to test for evenness of dust concentration within the chamber. The USF HEC can be used for studies using gases and/or particulates. The chamber measurements are 4.16 ft x 2.67 ft x 6.75 ft, for a total volume of 75 ft3 or 2.13 m3 …
Environmental And Community Health In South San Diego County: A Behavior Analysis Of Recreational Ocean Users Along Imperial Beach, California, Trista Brophy
USF Tampa Graduate Theses and Dissertations
Garbage & sewage runoff into the Pacific Ocean at the shoreline along the U.S./Mexico Border region poses serious health and environmental threats. The purpose of this study was to analyze the current beach users’ behavioral factors that may be linked to illness prevalence from Coronado Island to the U.S./Mexico border at Imperial Beach in San Diego County. It is a continuation of a study completed by Wildcoast and Imperial Beach Clinic in 2011. The study tried to answer the following two major questions: How have the number of illnesses reported by users along South San Diego County beaches changed in …
Statistical Modeling Of Carbon Dioxide And Cluster Analysis Of Time Dependent Information: Lag Target Time Series Clustering, Multi-Factor Time Series Clustering, And Multi-Level Time Series Clustering, Doo Young Kim
USF Tampa Graduate Theses and Dissertations
The current study consists of three major parts. Statistical modeling, the connection between statistical modeling and cluster analysis, and proposing new methods to cluster time dependent information.
First, we perform a statistical modeling of the Carbon Dioxide (CO2) emission in South Korea in order to identify the attributable variables including interaction effects. One of the hot issues in the earth in 21st century is Global warming which is caused by the marriage between atmospheric temperature and CO2 in the atmosphere. When we confront this global problem, we first need to verify what causes the problem then we …
Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Ceramic Proppant, Humairat H. Rahman
Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Ceramic Proppant, Humairat H. Rahman
USF Tampa Graduate Theses and Dissertations
Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. Male workers (n = 100) from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected …
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh
USF Tampa Graduate Theses and Dissertations
Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser, electrically conductive product. The final product, calcined coke, is primarily used to make carbon anodes for the aluminum industry and recarburizing agent for industries such as the steel industry. If not appropriately controlled, the calcining process could lead to excess production of particulate emissions from either handling or storing of raw coke, or from the …
Investigating The Determinants Of Recycling Behavior In Youth By Using Theory Of Planned Behavior., Tejaswini Gadiraju
Investigating The Determinants Of Recycling Behavior In Youth By Using Theory Of Planned Behavior., Tejaswini Gadiraju
USF Tampa Graduate Theses and Dissertations
The aim of this study is to understand the determinants that influence the youth recycling behavior intention. In other words, this study wants to know the motivations and barriers behind university students’ recycling behavior. The Theory of Planned Behavior (TPB), which provides a theoretical framework for systematically identifying the determinants of recycling behavior, is the basis for this study. Along with the TPB variables, additional predictor variables (moral norm, past experience, knowledge of how and what to recycle, knowledge of consequences, and inconvenience) that can influence behavior intentions were tested in the study. Online survey was used to collect the …
Comparison Of Urinary Pahs Among Firefighters And Asphalt Pavers, Theodore Aquino
Comparison Of Urinary Pahs Among Firefighters And Asphalt Pavers, Theodore Aquino
USF Tampa Graduate Theses and Dissertations
Firefighters and asphalt pavers are exposed to polycyclic aromatic hydrocarbons (PAHs) during various work activities. The purpose of this study was to evaluate urinary PAH levels and compare these bio-monitoring levels among firefighters, asphalt pavers, and non-occupationally exposed individuals. The National Institute of Standards and Technology (NIST) urinary PAH levels were used for non-occupationally exposed controls. When compared to the NIST standard for smokers and non-smokers, firefighters demonstrated statistically significant differences in urinary concentration differences for the following metabolites: 2-OH-fluorene, 3-OH-fluorene and 1-OH-pyrene, which were lower in firefighters than the NIST mean for smokers. 1-OH-phenanthrene, 2-OH-phenanthrene and 3-OH-phenanthrene were higher …
