Dust Collection Characteristics of Porous Filter Mediums

Lab and Field Scale Modeling of Near Miscible CO2 Injection in Different Porous Mediums

The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

Compression behavior of porous dust agglomerates

Context. The early planetesimal growth proceeds through a sequence of sticking collisions of dust agglomerates. Very uncertain is still the relative velocity regime in which growth rather than destruction can take place. The outcome of a collision depends on the bulk properties of the porous dust agglomerates. Aims. Continuum models of dust agglomerates require a set of material parameters that...

Molecular Hydrogen Formation on Porous Dust Grains

Recent laboratory experiments on interstellar dust analogues have shown that H2 formation on dust grain surfaces is efficient in a range of grain temperatures below 20 K. These results indicate that surface processes may account for the observed H2 abundance in cold diffuse and dense clouds. However, high abundances of H2 have also been observed in warmer clouds, including photon-dominated regi...

Bronchographic Contrast Mediums.

In a study of 102 bronchograms for purposes of comparing the contrast medium Visciodol(R) (a mixture of iodized peanut oil and powdered sulfanilamide) with Iodochlorol(R) (an iodized poppyseed oil), it was observed that Visciodol is more readily administered, produces better bronchograms with less alveolar filling and clears from the lungs far more rapidly and completely than does Iodochlorol. ...
