By analogy with what astronomers presently observe to happen in regions of star formation, it is thought that the solar system began as a cloud of gas and dust comprising such preexisting elements.
Further, the dust fractions comprised both noble and valuable metals but also contaminants that need to be taken into account when further processing is planned.
This group, as identified on the book's dust jacket, comprises Mary McCarthy, Edmund Wilson, Philip Rahv, Robert Lowell, Jean Stafford, Elizabeth Hardwick, Hannah Arendt, Allen Tate, Caroline Gordon and Diana Trilling.
Industrial processes handling combustible dusts usually comprise numerous pieces of equipment, such as grinders, mixers, dryers, classifiers, dust collectors, and storage hoppers, interconnected by a more or less complex network of pipes and conveying systems.
This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming.
Various authors show that the increase of dust mass in the Milky Way ISM is mainly governed by grain growth through the accretion of gas phase metals onto the grains (elements comprised of dust grains are referred to as "metals") (Dwek, 1998; Inoue, 2003; Zhukovska et al., 2008; Draine, 2009; Inoue, 2011; Asano et al., 2013).
If grip is important but you still require a wooden look, then there are many composite manmade decking boards comprised of wood dust and resin that look very realistic.
The Mourdi Depression (Dépression du Mourdi) is "a corridor of sand and dunes swept by the harmattan," a cold dry trade wind comprised of sand, dust, and grit.
The baseline data for the present study were collected between May and August 2009, and comprised personal total dust measurement, spirometry and a questionnaire on respiratory symptoms.
This debris layer, comprising rock fragments of all sizes down to fine dust, is called regolith.
Preindustrial δ34S signatures in Greenland ice cores were comprised of marine biogenic emissions, continental dust sources, background volcanism, and continental biota [7].
