Probabilistic Model For Laser Damage To The Human Retina, David A. Wooddell Jr.

Theses and Dissertations

Understanding how lasers interact with media during propagation is a premiere field of physics. The subject area known as laser bioeffects explores laser interactions with biological cells, tissues, organs, and bodies. This research includes laser applications used in medicine, establishes safe exposure limits for industry and academia, and generally studies the many effects of laser light on living creatures. The bioeffects community relies heavily on deterministic modeling and simulation tools to support experimental research into damage thresholds and laser effects. However, recent laser applications require a probabilistic approach to support risk management and analyses methodologies. Some probabilistic models exist, but …

Comparative Analysis Of Two Biological Warfare Air Samplers Using Live Surrogate Agents, James C. Enderby

Theses and Dissertations

The United States Air Force has several high-volume biological air samplers, including the XMX/2L-MIL and the Biocapture 650. Limited information is available on either in terms of its collection of viruses and bacteria. However, previous research on the XMX/2L-MIL has determined that modifications to the secondary flow rate and the use of a virus preserving collection media may provide improved virus collection rates. In this thesis, these modifications were investigated to determine their impact on the collection of viral and bacterial aerosols. Additionally, relative collection rates were compared against those for the Biocapture 650. MS2 bacteriophage was the viral surrogate …

Effects Of Standard Labor-Wear On Swimming And Treading Water, John Amtmann, Edd, Les Harris, William K. Spath, Charles Todd, Phd

Applied Health Sciences

We tested the hypothesis that occupational clothing would impair performance during swimming. The sub questions included: (1) Will the standard work wear of a railway worker or laborer impede swimming ability? (2) Will this clothing impact the individual’s ability to tread water? We addressed the research questions with three hypotheses. Analysis showed statistically significant p-values and all three null hypotheses were rejected in favor of the three research hypotheses, showing strong evidence that standard labor wear had adverse effects on 11.43 meter/12.5 yard swim time, water treading time and rate of perceived exertion (RPE) during water treading. The mean swim …

Occupational Exposure And Risk Of Skin Cancer In A Multinational European Study, Simona Surdu

Legacy Theses & Dissertations (2009 - 2024)

Non-melanoma skin cancers (NMSC) comprise more than one third of all cancers, and are increasing worldwide. The most common NMSC are Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC). Studies on humans and animals suggest that sunlight and arsenic play important roles in the pathogenesis of these skin malignancies. However, the number of epidemiological studies focusing on NMSC in workers exposed to ultraviolet (UV) radiation or airborne arsenic is limited, and the findings are contradictory.

Click here for the English version of this report

Une nouvelle technologie d’alarmes de recul de véhicule lourd a fait récemment son apparition sur le marché. Cette technologie, basée sur l’utilisation d’un signal large-bande (bruit de type « pschitt- pschitt ») serait, selon le manufacturier, plus sécuritaire pour les travailleurs tout en causant moins de nuisance environnementale que l’alarme tonale conventionnelle (bruit de type « beep-beep »). Il demeurait toutefois difficile de se prononcer sur la supériorité de cette technologie puisqu’il existe très peu d’études scientifiques indépendantes et rigoureuses portant sur celle-ci.

Cette étude visait à comparer la nouvelle technologie …
