→ skos:note → "A 'stagnation zone' is an area of a flow where some part of it
is for a long time or permanently retained. As a result, the effective
capacity of the flow is reduced, although formally all of it remains in the
system. Consequently, the introduction of dead spots results in the actual
absorption of harmful flow into the pathway."@en

some part of it is for a long time or permanently stagnant, to a flow
containing such areas."@en
→ skos:example → "A respirator.<br/> Harmful dust is trapped in the filter (a
typical dead zone), technically staying in the system but causing no
harm."@en
