Symmetry principles for the design of radiofrequency pulse sequences in the nuclear magnetic resonance of rotating solids.
In 1930, the authorities installed sedimentation tanks which allowed the heavier solids to deposit.
The higher inorganic content of the biofilm may have resulted from deposition of inorganic solids owing to the lower flow velocities applied in this study.
On the following day, the sample with crucible was weighed and total solids were estimated by difference.
The singularities are known as disclinations and are the orientational analogues of dislocations in solids.
Two-dimensional polygons and threedimensional polyhedra (curved or linear) are widely recognized examples of solids.
Because glasses are metastable solids, they can support a considerable mechanical stress, especially over short periods of time.
