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 the H …

Occupational Risks And Hazards Associated With Firefighting, Laura Walker

Graduate Theses & Non-Theses

Annually about 100 firefighters die in the line duty, in the United States. Firefighters know it is a hazardous occupation. Firefighters know the only way to reduce the number of deaths is to change the way the firefighter (FF) operates. Changing the way a firefighter operates starts by utilizing traditional industrial hygiene tactics, anticipating, recognizing, evaluating and controlling the hazard. Basic information and history of the fire service is necessary to evaluate FF hazards. An electronic survey was distributed to FFs. The first question was, “What are the health and safety risks of a firefighter?” Hypothetically heart attacks and new …

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

USF Tampa 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

USF Tampa 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 …

Efficiency Evaluation Of N95 Ffrs Under Cyclic And Constant Flows, Ali Bahloul, Fariborz Haghighat, Reza Mostofi, Alireza Mahdavi, Claude Ostiguy

Rapports de recherche scientifique

On trouve des particules ultrafines (PUF), soit des particules dont le diamètre (D_p) est inférieur à 100 nm, dans de nombreux milieux de travail industriels, où leur inhalation peut, à long terme, causer de graves problèmes de santé. Dans certains contextes, les mesures d’ingénierie et les contrôles administratifs sont insuffisants pour protéger adéquatement les travailleurs contre l’exposition aux PUF. Un dispositif de protection personnel est alors requis, et les appareils de protection respiratoire à pièce faciale filtrante (APR) de type N95 sont ceux qu’utilisent le plus couramment les travailleurs de l’industrie et de la santé.
