4.   It is likely that in these experiments there was a local unstable region in the entry boundary layer, but with subsequent decay of the amplified disturbances.

5.   However, the lowest values of the Reynolds number at which transition occurs are well below the minimum value at which theory indicates the existence of an unstable region.

6.   And these are issues that are magnified when fabs are located in politically unstable regions, analysts say.

7.   Azerbaijan wants to develop its oil reserves, but foreign companies are reluctant to invest or build vulnerable pipelines in an unstable region.

8.   Berisha, for a long time viewed by the United States and other western governments as a model of stability in an unstable region, leads the Democratic Party.
