At the start of a cohort, we assume that the barn is seeded with an amount of infectious dust D0 (mg).
Doing this can also damage the blade and generate an enormous amount of dust, which is an eye and mucus membrane irritant.
If there is a possibility of generating a significant amount of dust, conduct work in a fume hood.
"But, as the Apollo astronauts learned, you can have a devil of a time overcoming even a small amount of dust".
Dust sampling was not equally distributed among the seasons; whereas almost an equivalent amount of dust samples was taken during winter and spring (25% and 28%, respectively), less dust sampling was performed in the summer season (14%) and more during autumn (33%).
X-ray observations by the Chandra X-ray Observatory revealed six sources in the HDF, which were found to correspond to three elliptical galaxies: one spiral galaxy, one active galactic nucleus and one extremely red object, thought to be a distant galaxy containing a large amount of dust absorbing its blue light emissions.
Consequently, the impacts of interstellar dust have a potential ability to supply a significant amount of dust in the diffuse dust cloud in the asteroid belt.
In addition to the near-surface gases and the extensive sodium-potassium cloud detected around the Moon (see the section Effects of impacts and volcanism below), a small amount of dust circulates within a few metres of the lunar surface.
It is reported that the presence of a small amount of dust in atmosphere has a negligible effect on the performance of PV module (Siddiqui and Bajpai 2012).
Because sanding of wood floors liberates a large amount of dust, the sanding of a Fabulon-coated wood floor may account for the unusually high concentrations we measured in dust (more than 8 times higher than first dust sample) and blood observed in the female resident of home #1.
A certain amount of dust and Atlantic spray on the breeze, a sound system blaring Azonto – a local music sensation – just a bit too loud, fearless children lining up to show off their moves, and an orderly row of canopies where the hot and the tired sit down on plastic chairs and take stock.
