Infrared analysis showed a similar lack of crystalline order about the PO4 anions in the ACP structure [7].
The lack of sharp peaks indicates the absorbance of any ordered crystalline structure, confirming the results from the silica activity index and the lack of crystalline phase.
Basaltic volcanic ash is generally considered unlikely to be a respiratory health hazard due to its often coarse nature (with few particles sub-10 μm diameter) and lack of crystalline silica.
Thermal and spectroscopic properties of the annealed cast syndiotactic polystyrene (SPS) films were investigated and it was shown that the sample annealed at lower temperature than 170°C exhibited the presence of a conformational order but lack of crystalline regularity.
It needs to be emphasised however, that the lack of crystalline silicate features in the infrared spectrum does not mean that the crystalline silicates are absent; in particular in optically thin dust shells, they may simply be colder than the amorphous silicates (Kemper et al., 2001).
The most pronounced effect was the existence of an intense birefringence which lacked any sign of crystalline structure as observed by polarized light microscopy as well as the existence of a non-birefringent area in some of the same samples.
Hot spots North Norfolk North Norfolk doesn't have particularly good rail links, is patchy in terms of its housing provision and the sea lacks the crystalline freshness of the west coast.
The lack of identifiable crystalline cellulose-binding domains and the poor performance of the identified enzymes on crystalline cellulose – despite active degradation of this substrate by whole cells – has led to the hypothesis that cellulose degradation by this species relies on an unusual degree of cell-enzyme synergy [56], and perhaps even utilizes a cell-based, non-enzymatic process [22].
The novel, about a 12-year-old boy growing up in Southern California in the 1980's, lacks the crystalline style of "The Hours," but it shares the later novel's gallant interest in women's emotional lives.
Although the real proteins form crystalline or paracrystalline lattices on the cell surface [41], we are restricted at this time to using an aqueous group additivity model for lack of a crystalline analog.
