Vessel traffic places the sensitive environmental, natural, and cultural resources of Washington’s outer coast at risk of oil or hazardous materials spills. In 1995, International Maritime Organization established the Area to be Avoided off the Washington Coast (ATBA) to reduce this risk. Annual estimates of vessel compliance with the ATBA...
The Oregon State University Mars MM5 was used in a comprehensive high-resolution study of northern polar summertime circulations. Three simulations (Ls = 120, Ls = 135, and Ls = 150) characterize the changing circulation. The atmosphere is dry, and model dynamics are hydrostatic. A modified TES thermal inertia map provides...
Modeling of slope flow circulations in idealized axisymmetric craters is used to understand (1) the large surface pressure amplitude observed in Gale Crater by the Rover Environmental Monitoring Station and (2) the shallow convective boundary layer (CBL) suggested by Curiosity imagery. Air temperatures vary within craters with greater amplitudes than...

For a key season in the annual water cycle (L[subscript s]~120°) a mesoscale model is used to study atmospheric water vapor and water ice clouds in the northern polar region of Mars. Model results at high-resolution (15 km) allow the examination of various mesoscale aspects of the circulation in this...
Clostridium difficile is the causative agent of the majority of antibiotic associated diarrheas. C.
difficile spores are recognized as the morphotype of transmission, infection and persistence.
However, there is a lack of knowledge on how C. difficile spores interact with the host’s
epithelial surfaces. In this context, we have characterized...
Clostridium perfringens type A is the causative agent of a variety of histotoxic and enteric diseases. The ability of C. perfringens spores to germinate in vivo might be due to the presence of nutrient germinants in the host tissue and blood. In the current study, we investigated the ability of...
