Sentence examples for for dust alignment from inspiring English sources
The amount of Δ χ para required for dust alignment has been quantitatively discussed based on laboratory experiments using orthopyrox-ene grains containing a low concentration (~1 mol.%) of Fe3+ ions; orthopyroxene has been detected in circumstel-lar regions by infrared emission spectroscopy (Honda et al., 2003).
The validity of a dust alignment model based on diamagnetic anisotropy is quantitatively examined by obtaining mΔχ dia values at sizes equivalent to those of dust particles.
A simple model was sufficient to fit the near-infrared polarimetric data, but the dust alignment mechanism remains unknown and the dust properties are not well constrained.
In diffuse clouds, the concentrations of magnetic ions in the dust particles are considered to be too low to cause dust alignment.
As mentioned above, it is essential to determine the dust alignment mechanism to obtain reliable field directions from polarimetry data, because the dust alignment mechanism determines the relationship between the magnetic field direction and the polarization.
In these regions, dust alignment may be caused by Δχ dia (Chihara et al., 1988; Uyeda et al., 2003b).
For dust you are and to dust you will return.
Environmental dust samples were analyzed for dust mite, cockroach, rodent urinary protein, endotoxin, and fungi.
Finally, researchers and risk assessors estimate exposure to chemicals in dust by multiplying dust concentrations by highly uncertain exposure factors for dust ingestion (U.S. Environmental Protection Agency 2011).
Sweep the floor for dust and debris.
