The till was selected to be representative of material used in Saxony and Brandenburg, areas with a history of using clay barriers to protect buildings [6].
The method establishes a series of selection criteria that ensure that the data used in the statistical analysis are significant and truly representative of material behavior.
Repeatability and reproducibility of the evaluation method is ensured to facilitate the representative ranking of materials based on droplet impact erosion resistance being a key material property for durable steam turbine blade designs.
The complex hydride NaAlH4 is representative of novel materials under development and will be used as the basis for properties, such as temperature dependent kinetics, which influence the integrated system configurations and component sizing.
It is interesting to notice how thin some of the layers are (1 2 μm). Figure 3 shows some spectra representative of the materials identified in the samples VIC 2, VIC 5 and VIC 7. In order to obtain information on the distribution of both organic and inorganic materials, layers were selectively sampled (when possible) using tungsten needles [21] under the stereomicroscope.
As the representative of base materials [10, 12, 13], Fe3O4 magnetic nanoparticles (MNPs) have attracted a significant amount of interest during the past few decades owning to their merits, such as good stability, facile synthesis, high surface area, low toxicity, good biocompatibility, and especially unique magnetic responsivity [14].
This implies that central data from compositional analysis, animal feeding studies and overall risk assessment performed by industry and submitted to national and international regulatory bodies as evidence as safety, is not representative of the materials actually produced by farmers and delivered onto the commercial market.
Sediment CRMs are freeze-dried and thus potentially not representative of sediment materials normally extracted.
"It's not clear how well meteorites are representative of the material in the solar system," says Akira Fujiwara, a planetary scientist with Japan's Institute of Space and Astronautical Science ISASS).
We can approximate the surface elastic constant as S = E bulk × r 0, where r 0 is a characteristic length-scale representative of the material structure.
