It is possible that any changes observed were due to the receipt of educational materials on the appropriate use of quinolones, since both groups of physicians received educational materials.
The corrosion studies' results for nanopowders of borides and carbides are shown in Figs. 1 and 2. It was noted that, in both groups of compounds, corrosion resistance of materials was comparable and attributable primarily to the electrolyte acidity.
Thus, birds at both sites had access to all groups of materials, but the degree of access may have differed between sites and may influence the differences in nest morphology and composition that we observed.
Both groups of individuals represent highly interesting material for further analysis, in particular the latter group whose resistance could be ascribed to a different mechanism which does not involve the presence of viniferins.
The two groups of materials most often spotlighted in this strategy are nano-scale pigments, which are used in sunscreens and cosmetics, and nano-silver particles.
These two groups of materials were compared, moreover the impact of microwave radiation on their physicochemical properties was checked.
The main groups of materials used in aircraft construction have been wood, steel, aluminum alloys with, more recently, titanium alloys, and fiber-reinforced composites.
Three different groups of materials were tested: (1) fusible alloys such as BiSn and BiSnZn, (2) thermoplastic polymers called Rigidax®, and (3) fixturing waxes.
Several groups of materials (composites, nanocomposites, nanocrystalline metals, wood) are considered with view on the effect of nanostructured interfaces on their properties.
