Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4+ T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants …


Hexavalent Chromium Exposure To Military Aircraft Painters, Doug Rosaaen Jul 2017

Hexavalent Chromium Exposure To Military Aircraft Painters, Doug Rosaaen

Graduate Theses & Non-Theses

Military aircraft routinely operate in harsh, corrosive environments that necessitate aggressive maintenance methods and products to prevent deterioration. Three primary tasks associated with corrosion control of these aircraft are abrasive blasting, sanding, and primer paint application. The most frequently used primer paints for these applications contain chromium VI (Cr VI) in the form of barium chromate and strontium chromate. Due to aircraft size and the nature of these tasks, control of Cr VI exposures is often difficult.

Numerous studies of chromate related industries have identified worker exposures in excess of the OSHA PEL of 5 μg/m3. Long-term analysis of chromate …


Ability Of Physiological Strain Index To Discriminate Between Sustainable And Unsustainable Heat Stress, Dwayne Wilson Jun 2017

Ability Of Physiological Strain Index To Discriminate Between Sustainable And Unsustainable Heat Stress, Dwayne Wilson

USF Tampa Graduate Theses and Dissertations

Introduction: Assessment of heat strain is an alternative approach to assessing heat stress exposures. Two common measures of heat strain are body core temperature (TC) and heart rate (HR). In this study TC was assessed by rectal temperature (Tre). Physiological Strain Index (PSI) was developed to combine both Tre and HR into one metric. Data collected from progressive heat stress trials were used to (1) demonstrate that PSI can distinguish between Sustainable and Unsustainable heat stress; (2) suggest values for PSI that demonstrate a sustainable level of heat stress; and (3) determine if clothing or …

La conception sécuritaire des excavations souterraines requises pour l’exploitation minière nécessite une bonne connaissance de l’état des contraintes naturelles du massif rocheux.

À ce jour, la seule façon de connaître ces contraintes avec une justesse acceptable consiste à réaliser des mesures in situ. Or, les techniques de mesure de contraintes couramment utilisées dans les mines du Québec se heurtent à des limites importantes sur le plan de la fiabilité et de la précision, ce qui laisse toujours planer un doute sur la validité des résultats obtenus, exposant par le fait même les travailleurs miniers à des risques potentiels …


Influence Of Environmental Parameters On Mold Sampling Results, Benjamin Fishman Jun 2017

Influence Of Environmental Parameters On Mold Sampling Results, Benjamin Fishman

USF Tampa Graduate Theses and Dissertations

Mold is a type of fungus present in nearly all environments. Mold thrives under several environmental parameters such as high humidity and an adequate food source. A professional, such as an industrial hygienist, can measure mold in indoor and outdoor environments. Industrial hygienists commonly use a cascade impactor with a culture plate to capture air within a sampling area. While collecting air samples, environmental parameters such as temperature, humidity, and carbon dioxide are recorded. A laboratory then cultures and analyzes the samples, identifying the types and amounts of viable mold found in the sampling area.

In this study, a data …

Exploring The Health Effects Of Precarious Employment By Sex/Gender Using Mixed Methods, Kathleen Flandrick Jun 2017

Exploring The Health Effects Of Precarious Employment By Sex/Gender Using Mixed Methods, Kathleen Flandrick

Dissertations and Theses

Employment in the United States has changed dramatically since the mid-1970s. Labor market forces like globalization and diversification of the American workforce have led to a heavily segmented labor market where new types of flexible employment such as temporary, contingent, and nonstandard work arrangements are increasingly common. These newer types of work are often on the lower end of the precarious employment continuum, categorizing jobs by their degree of: 1) temporariness, 2) disempowerment, 3) vulnerability, 4) compensation (wages), 5) rights, and 6) ability to exercise worker rights. The increase in precarious employment likely disproportionately affects women when compared to men, …


Effects Of Temperature On The Emission Rate Of Formaldehyde From Medium Density Fiberboard In A Controlled Chamber, William Swankie Jun 2017

Effects Of Temperature On The Emission Rate Of Formaldehyde From Medium Density Fiberboard In A Controlled Chamber, William Swankie

USF Tampa Graduate Theses and Dissertations

Formaldehyde is a colorless gas that is found naturally in the environment. It is a popular additive in many consumer products including composite wood products. Composite wood products are engineered wood panels produced from pressing pieces, chips, particles, or fibers of wood together at high temperatures held together with a bonding agent. This bonding agent is often formaldehyde-containing resins that are known to release formaldehyde over time. This is concerning because of the carcinogenic classification of formaldehyde, the wide spread application of composite wood products, and the increasing amount of time spent in the indoor environment.

A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein

Dissertations, Theses, and Capstone Projects

The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels and …

• Electronic cigarettes (e-cigarettes or e-cigs) are battery-powered devices that deliver vaporized nicotine and other substances, such as flavorings, to users without smoke or combustion. They are commonly marketed as smoking cessation tools and, as such, are promoted as being a healthier alternative to smoking.

• A common misperception is that that e-cigarettes only release water vapor. In reality, though, these devices release nicotine and other chemicals in a vapor form that can expose both the user (a.k.a., the vaper), as well as those in the immediate vicinity, to those contaminants. While the health risks of e-cigarettes compared to regular …
