The extraintestinal pathogenic Escherichia coli (ExPEC) H30 subclone of sequence type 131 (ST131-H30) has emerged abruptly as a dominant lineage of ExPEC responsible for human disease. The ST131-H30 lineage has been well described phylogenetically, yet its plasmid complement is not fully understood. Here, single-molecule, real-time sequencing was used to generate the complete plasmid sequences of ST131-H30 isolates and those belonging to other ST131 clades. Comparative analyses revealed separate F-type plasmids that have shaped the evolution of the main fluoroquinolone-resistant ST131-H30 clades. Specifically, an F1:A2:B20 plasmid is strongly associated with ...

A variety of paint products are used for their aesthetic and anti-corrosive properties. Isocyanates are consistently found in automobile paint products, particularly in clear coat polyurethane products. Clear coat is typically sprayed via pressurized air by means of an auto-spray robot. In clear coat repair situations, manual, air-powered spray guns are used, and manual spray Operators administer the clear coat material. The isocyanates are a primary anti-corrosive agent in polyurethane products. The Occupational Safety and Health Administration (OSHA) has not established a Permissible Exposure Limit (PEL). The National Institute for Occupational Safety and Health (NIOSH) and American Conference of Governmental ...


Assessment Of Prolonged Occupational Exposure To Heat Stress, Ximena Garzon-Villalba Garzon-Villalba 2016 University of South Florida

Assessment Of Prolonged Occupational Exposure To Heat Stress, Ximena Garzon-Villalba Garzon-Villalba

Graduate Theses and Dissertations

Heat stress is a recognized occupational hazard present in many work environments. Its effects increase with increasing environmental heat loads. There is good evidence that exertional heat illness is associated with ambient thermal conditions in outdoor environments. Further, there is reason to believe that risk of acute injury may also increase with the ambient environment. For these reasons, the assessment of heat stress, which can be done through the characterization of the wet bulb globe temperature (WBGT), is designed to limit exposures to those that could be sustained for an 8-h day. The ACGIH Threshold Limit Value (TLV) for heat ...

Assessing Excessive Noise Exposure Of Music-Oriented Nightclub Employees, Aiyanna Fitzgerald

Graduate Theses and Dissertations

Much research has gone into noise-induced hearing loss (NIHL) and the effects of high intensity noise levels on the hearing mechanism of individuals. A study by the National Institutes of Health has established that high intensity sounds can cause hearing damage of either a temporary, or worse, a permanent nature; regardless of the age of the person. While sound levels below 75 decibels are considered comparatively harmless and have been found not to cause any kind of permanent hearing loss; sound levels greater than 85 decibels and regular exposure of approximately 8 hours per day, on an average, has been ...

Workplace Predictors Of Perceived Quality Of Care In Nursing Homes, Winnie Chin, Laura Punnett, Rebecca Gore, Laura Kernan

UMass Center for Clinical and Translational Science Research Retreat

Nursing home quality of care (QOC) is a matter of public concern and public policy. Higher nurse-to-patient ratios have been shown to decrease rates of adverse outcomes. Positive nurse-doctor relationships also have a positive effect, which might translate to other clinical staff, such as nursing aides, who perform the majority of direct care tasks in nursing homes. This cross-sectional study examined whether workplace factors in nursing homes were associated with QOC as evaluated by staff members themselves. Surveys were distributed to personnel in 24 nursing home facilities in the Northeast U.S. A total of 1463 respondents provided ratings of ...

Evaluation Of A Sprinkler Cooling System On Inhalable Dust And Ammonia Concentrations In Broiler Chicken Production, Sarah Ashlee Williams Ischer

Theses and Dissertations

Indoor air contaminants such as dust and gases are present in concentrations that may be hazardous to worker health in poultry production. Poultry dust may contain inflammatory agents (e.g., endotoxin) and inhalation exposure has been associated with pulmonary symptoms. The current control practice to reduce worker exposure to poultry dust is the use of respiratory protection (e.g., filtering face-piece respirators). Limited research has been conducted to evaluate engineering controls to reduce dust concentrations in broiler chicken production. Therefore, the purpose of this research was to evaluate the effectiveness of a water sprinkling system to reduce inhalable dust and ...
