In ditches a great variety of materials may act as sorbents for organic contaminants: grass, leaves, wood debris or sediments.
Chemical analysis and particle size distribution showed that MGR is a non-reactive material and may act as a filler.
After droplet etching, the nanohole openings are surrounded by walls that are crystallized from droplet material and may act as quantum rings [19, 22 25].
Conversely, a number of studies suggest that certain factors, particularly greater access to social and material resources, may act as buffers and predispose individuals to less severe trajectories of depression.
Furthermore, Reticulitermes incorporates termicin and GNBP2 in nest materials that may act as an external recognition system.
Ultramarine is still used as a pigment of building materials, and, it may act as a non-traditional pozzolanic material as well.
However, in some cases impurities of differing valence (that is, possessing different numbers of bonding electrons) may be included in the material, and these impurities may act as donors or acceptors of electrons.
Clearly the share price performance of Lloyds between now and 5 June 2009 may act as a material determinant of acceptance levels.
An exogenous material capable of reducing peptide toxicity may act by two opposite, postulated mechanisms: (1) by decreasing monomer nucleation and hence blocking aggregation, which would result in a reduction in the formation of ADDLs, fibrils, and plaques; or (2) by disaggregating amyloid plaques or fibrils.
A special product (CaLoSiL®-Micro) contains calcium hydroxide particles with a particle sizes of 1 3 micrometres which may act as a crack-bypassing material in the porous building material.
