Studies of PM in indoor heritage environments have generally focused on dust, which is one of the characteristic sizes -the largest- of PM.
Federal investigators focused on dust from the mixing and drying of synthetic rubber and other ingredients as a possible explanation for the explosion.
Numerous studies have been performed on dust lifting, however, very few investigations have focused on dust layers with high volume fractions.
The research presented in this paper is focused on dust explosions of coarse and fine flocculent (or fibrous) samples of wood and polyethylene.
They focused on dust transported long distances, as these particles are small and light enough to be lifted and carried through the atmosphere for days before settling thousands of kilometers away from their source.
With a new tablet (the 8 inch Tablet Z3 Compact), the Xperia Z3 Mini, and the flagship Xperia Z3, the Japanese company has continued with the aluminium and glass design of previous Xperia hardware, and focused on dust and waterproofing, as well as reducing the weight while increasing the performance.
To date, a variety of methods have been used to assess pesticide exposure among farmworker families, mostly focusing on dust and handwipe samples.
Our findings agree with other research showing relationships between bed dust exposures and respiratory symptoms, although many of the previous studies have focused on dust mite allergens (Garrett et al. 1998; Marks et al. 1995a, 1995b; van den Bemt et al. 2004).
The research team focused on dust-mite-induced allergies because dust mites are ubiquitous and thrive in warm, humid climates.
As a tiger sinks its teeth into the world's neck, we focus on the dust bunnies under the bed and the floorboards that need replacing on the deck.
