While foaming at low temperature (40 °C) leads to foams with the highest cell density (∼1012 1014 cells/cm3), the foam expansion is restricted (d∼0.7 0.8 g/cm3).
For example, in pollen tubes and root hairs which undergo polarized cell growth, expansion is restricted to the tip of the elongating cells.
This moss is particularly well suited for plant polarized cell growth studies, as in its protonemal phase, expansion is restricted to the tip of its cells.
If so, should such knowledge expand in parallel with other biomedical information, or should any such expansion be restricted by its relevance to changes in clinical performance (the 'barefoot doctor' model)?
Expansion of Highbury was restricted because the East Stand had been designated as a Grade II listed building and the other three stands were close to residential properties.
The turbine Parsons invented in 1884 utilized several stages in series; in each stage the expansion of the steam was restricted to the extent that allowed the greatest extraction of kinetic energy without causing the turbine blades to overspeed.
Italy was one of the European refugia during the Last Glacial Maximum, but the post-glacial expansion of its refugial populations was restricted by the Alps to the North [24].
Thus, the expansion of CD45RA+CD25dimcells with aging was restricted to the CD4+ T cell compartment.
The western and eastern Cytb clades within the marsh rice rat may represent expansions from different glacial refugia which the species was restricted to during a glacial period.
