For low volume ENMs with bulk material of known ecotoxicity, comprehensive investigation has to be performed.
For low volume ENMs where no bulk material is available, the bulk material shows no ecotoxicity, or ecotoxicity of the ENMs is expected due to their physico-chemical properties, a screening test has to be performed.
Thus, the BFR provides a relative measure of the enrichment of the corresponding parental allele in the appropriate bulk (LDN for the low bulk and RSL65 for the high bulk).
However, drawbacks such as grate blocking, channeling, and bridging are found in the downdraft gasifiers, typically for feedstock with low bulk density.
The in vitro total lung dose of insulin microparticles was improved and favored for powders with low bulk density and small primary particle size, with reduction of deposition in the extrathoracic region.
A possible explanation for the relatively low bulk density of mixture B could be an optimised pore space closure in order to limit outward expansion and swelling pressure of the compacted mass.
Combining both libraries, a total of 53.4 and 61.2 million paired end reads were produced for the High and Low bulk, respectively.
Moreover, V-shaped curve also appears at low bulk concentration for C8PO3EO3S and C8PO6EO6S with addition of NaCl.
When quantified using the change in bulk density, having an initially low bulk density compensated for large increases in bulk density during conveying and powder with lower bulk density pre-transport showed better wettability post transport.
Bilobate comets are thought to be primordial because they are rich in supervolatiles (for example, N2 and CO) and have a low bulk density, which implies that their formation requires a very low-speed accretion of two bodies.
