than the molecular diffusivity in the turbulent core.
2. Fluid dynamics
- In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past stir bar. This phenomenon is most visible behind large objects in swift-flowing fluids. The concept of eddy is often used in turbulence flow.
With and without stir,① Relying only on molecular agitation

1.2 Structure of Planning for Security
Clearly, the subject of security has wide implications that reach far beyond the jurisdictional limits of the airport to central government itself. Planning to meet the needs of a security emergency requires the involvement of a number of organizations, such as:

Potential bio-accumulation of nanoscale particles.
Accumulation of a substance within a species can occur due to lack of degradationor excretion
Many nanoparticles are not biodegradable.
If nanoparticles enter organisms low in the food web, they may be expected to accumulate in organisms higher in the food web.
Very little is understood about possible health
