چکیده
A system is disclosed for condensation particle counting in conjunction With modifying an aerosol to enhance the for mation and groWth of droplets of a selected Working ?uid, preferably Water. Before saturation With the Working ?uid, the aerosol is exposed to an aerosol modifying component, preferably a vapor including molecules that are adsorbed onto surfaces of the particles or other elements suspended in the aerosol. Adsorption alters the surface character of the suspended elements toWards increased a?inity for the vapor of the Working ?uid, to promote the formation and groWth of Working ?uid droplets. The droplets are optically detected to indicate numbers and concentrations of the suspended elements.

متن کاملSulfurihydrogenibium yellowstonense sp. nov., an extremely thermophilic, facultatively heterotrophic, sulfur-oxidizing bacterium from Yellowstone National Park, and emended descriptions of the genus Sulfurihydrogenibium, S. subterraneum and S. azorense
A novel thermophilic, sulfur-oxidizing Gram-negative bacterium, designated strain SS-5, was isolated from the Calcite Hot Springs in Yellowstone National Park, USA. The cells were motile rods (1?2–2?8 mm long and 0?6–0?8 mm wide). The new isolate was a facultative heterotroph capable of using elemental sulfur or thiosulfate as an electron donor and O2 (1–18 %; optimum 6 %, v/v) as an electron a...

متن کاملOn Gaussian Expectation Propagation
In this short note we will re-derive the Gaussian expectation propagation (Gaussian EP) algorithm as presented in Minka (2001) and demonstrate an application of Gaussian EP to approximate multi-dimensional truncated Gaussians. 1 On Gaussian Distributions Here we will summarise some important equalities about the Gaussian density. A Gaussian density in Rn is defined by N (x;μ,6) := (2π)− 2 |6|− ...

Two novel denitrifying bacteria, designated strains MI55-1 and E9I37-1, were isolated from deep-sea hydrothermal vent chimney structures at the Iheya North hydrothermal field in the Mid-Okinawa Trough, Japan. Both isolates were strict chemolithoautotrophs growing by respiratory nitrate reduction with H2, forming N2 as a metabolic product. Oxygen (at low concentrations) could serve as an alterna...
