As its icy surface roasted at about 1000 kelvin, the comet disgorged a surprisingly broad dust tail and a fainter but pronounced tail of ionized gas.
Steve Wells, president of the Desert Research Institute, said the intensity of the current dust storms in Iraq "probably doesn't have much to do with destruction of desert pavements, but I can't say for sure". The fine particles blowing around in broad dust storms can come from great distances away, he said.
the age of someone's father— and I trembled for your luck, for your broad, dusted back, half shirted, walking away; I should have dropped to my knees to thank God you were alive, o my God, in whom I don't believe.
Gao is a low-rise city with broad, dust-red streets.
Nevertheless, systematic environmental magnetic studies on material from broader dust source regions are still sparse.
It consists of 15 papers peer-reviewed by two or more experts, covering a broad range of dust topics: solar system dust, interstellar dust, and intergalactic dust as well as light scattering, in-situ analyser developments, and laboratory astrophysics.
Initially, SOFIA will fly with nine first-generation focal plane instruments that include broad-band imagers, moderate resolution spectrographs that will resolve broad features from dust and large molecules, and high resolution spectrometers capable of studying the chemistry and detailed kinematics of molecular and atomic gas.
The outer rings of Uranus may be similar to the G and E rings of Saturn as E ring is extremely broad and receives dust from Enceladus.
A population specific job-exposure matrix (JEM) was used to categorize each job title into three broad categories of agents: organic dust, mineral dust, or gases/fumes.
Answers were analyzed using a previously published specific job exposure matrix (JEM) that provided a semiquantitative estimate (none, low or high) of exposure to three broad categories of agents: organic dust, mineral dust, or gas/fumes [ 16, 17].
Cold winter winds blow dust down broad and empty streets lined with boarded-up buildings in many neighborhoods.
