[1] We show how to predict flow properties for a variety of porous media using pore-scale modeling with geologically realistic networks. Starting with a network representation of Berea sandstone, the pore size distribution is adjusted to match capillary pressure for different media, keeping the rank order of pore sizes and the network topology fixed. Then predictions of single and multiphase pr...

Mixed wettability develops naturally on a pore scale in oil reservoirs after primary drainage. The invading fills interiors that become oil-wet by asphaltene deposition, while the residual water retreats into corners, masking them and retaining their wetness. This alteration hinders mobilization during secondary waterflood. Therefore, proper understanding of conditions controlling pore-scale im...

active as cloud condensation nuclei (CCN) and susceptible to wet deposition. However, an outstanding problem is whether the effects of chemical aging on their CCN activity are preserved when mixed with other organic or inorganic compounds exhibiting greater water-solubility. In this work, the CCN activity of laboratory-generated biomass burning aerosol (BBA) surrogate-particles exposed to OH an...

reduced adsorption of NO3–N and NH4–N by anionic and cationic resins, respectively. Kjonaas (1999) also Ion exchange resins have widely been used in mineralization studies observed no detectable effect of freezing on resin staof organic materials. However, the stability of resin (anionic and cationic) under changing physical environmental conditions is not bility. Lehmann et al. (2001) have obs...

The aim of this study was to investigate the characteristics of fundus autofluorescence (FAF) in patients with wet (exudative) age-related macular degeneration (AMD). Color fundus photographs, fundus fluorescein angiograms, indocyanine green angiograms, and FAF images were obtained from 61 patients (72 eyes) with exudative AMD. The FAF results for different patterns of exudative AMD were compar...

The 1993 flood of the Missouri River led to the abandonment of agriculture on considerable land in the floodplain. This abandonment led to a restoration opportunity for the U.S. Federal Government, purchasing those lands being sold by farmers. Restoration of this floodplain is complicated, however, by an imperfect understanding of its past environmental and vegetative conditions. We examined en...
