The "silent cycle" involves adding fast-growing plants and relying on them to consume the nitrogen, filling in for the bacteria work until their number increases.

Biogeochemical cycles always involve hot equilibrium states: a balance in the cycling of the element between compartments.

The initial cycle involved four-hour infusions given daily for five days.

One such cycle involves the nitrogen oxide species, which are the most responsible for ozone depletion in the stratosphere.

This cycle involves getting close, pulling away, and then getting close again.

Modal driving cycles involve protracted periods at constant speeds.

During passive carbonatogenesis, two metabolic cycles can be involved, the nitrogen cycle and the sulfur cycle.

The female reproductive system is extremely complex and the menstrual cycle involves several different hormones.

However, the cycle may involve transport and paratenic hosts.

The catalytic cycle for the Heck reaction involves a series of transformations around the palladium catalyst.
