Particulate Matter Identification in Lung Tissue from Deployers, Positive, and Negative controls Using Scanning Electron Microscopy and Energy Dispersive Spectroscopy (2013-2016) We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. Backscattered electron and secondary electron images of particulate matter in lung tissue were acquired. Inorganic particulate matter in the field of view of the image was analyzed using energy dispersive spectroscopy and subsequently identified and cataloged.

It is a table of values representing the square meters of each land cover type (NLCD 2016) present in the floodplain boundary (EPA enviroatlas 100 year) within NHDPlus medium resolution catchments identified by FEATUREID. In addition to square meters of land cover type, the percent of the total floodplain containing natural land cover (as determined by land cover classes 11, 12, 31, 41, 42, 43, 51, 52, 71, 72, 73, 74 90, and 95) and disturbed land cover (as determined by land cover class values 21, 22, 23, 24, 81, 82) is calculated.

The Haywired Earthquake Scenario This map shows the potential of widespread slope failures, in terms of landslide probability, triggered by a M7.0 scenario earthquake on the Hayward Fault in the 10-county area surrounding the San Francisco Bay region, California. The likelihood of landsliding was evaluated using an equation developed by Jibson and others (2000) that estimates landslide probability as a function of predicted Newmark displacement. Based on this equation, four landslide probability categories are established with their corresponding percent likelihood and displacement ranges: Low (0-2%; 0-1 cm), Moderate (2-15%; 1-5 cm), High (15-32%; 5-15 cm), and Very High (>32%; >15 cm).The seismic-landslide probability map covers the counties...
