1.   The free-running ratchet mechanism allow changes of direction to be made with finger and thumb, without releasing the handle.

2.   The mechanism allows for great variation and complexity in magma chamber sedimentation.

3.   What mechanism allows toadstools -- essentially very soft and squashy items -- to push through two inches of asphalt?

4.   This mechanism also allows for the encoding of composite works such as anthologies, in which individual texts may have different structural properties.

5.   Also, the foot mechanism allows some heel-to-toe bend, storing and giving off energy as the wearer walks.

6.   Electricity rates have been frozen for the last year, and a new rate mechanism would probably allow companies to raise rates this year, helping earnings.

7.   This important mechanism at least allows each country to monitor the flow of arms sales.

8.   Various mechanisms allow states to shield their citizens from prosecution, although the United Nations can slap sanctions on countries that harbor fugitives.

9.   We also need a mechanism to allow for our development.

10.   While the Higgs mechanism does allow particles to have mass, each value has to be individually determined from experiments and plugged into the theory.
