Abstract: An aerosol collection system and method. The system includes a bio-aerosol delivery device configured to supply bioparticles in a gas stream, a moisture exchange device including a partition member coupled to the gas stream and configured to humidify or dehumidify the bioparticles in the gas stream, and an aerosol collection medium downstream from the moisture exchange device and configured to collect the bioparticles. The method includes delivering bioparticles in a gas stream, humidifying or dehumidifying the bioparticles in the gas stream by transport of water across a partition member and into a vapor phase of the gas stream, and collecting the bioparticles by a collection medium.

Abstract: Computer-implemented methods and non-transitory computer readable storage media facilitate calculating outflow of water from a selected catchment. A computer-implemented method calculates an outflow of water from a selected catchment is calculated. An identification of a selected catchment from a plurality of catchments within a geographical area is received from a user workstation. A database of multilayered data is accessed, where the data includes hydrological data, geophysical data, and meteorological data for each of the plurality of catchments within the geographical area. From the multilayered data, one or more additional catchments are automatically identified within the plurality of catchments, to identify a group of navigated catchments that drain into the selected catchment. For a given time period, a model is generated determining an outflow of water from the selected catchment and the group of navigated catchments.

Abstract: A remote plasma enhanced CVD apparatus and method for growing semiconductor layers on a substrate, wherein a intermediate feed gas, which does not itself contain constituent elements to be deposited, is first activated in an activation region to produce plural reactive species of the feed gas. These reactive species are then spatially filtered to remove selected of the reactive species, leaving only other, typically metastable, species which are then mixed with a carrier gas including constituent elements to be deposited on the substrate. During this mixing, the selected spatially filtered reactive species of the feed gas chemically interacts, i.e., partially dissociates and activates, in the gas phase, the carrier gas, with the process variables being selected so that there is no back-diffusion of gases or reactive species into the feed gas activation region. The dissociated and activated carrier gas along with the surviving reactive species of the feed gas then flows to the substrate.

Abstract: A real-time rasterization system for converting plural polygonal pattern data into respective bits of a two-dimensional bit-map, wherein the respective bits of the bit-map and the locations thereof within the bit-map correspond to the shapes and locations of the polygons in a two-dimensional field and wherein the bit-map is divided into plural data stripes, each including plural scan lines having plural bits.
