The neutrons were timed to arrive just as the plutonium reached half of its peak density.
The ionisation degree of the metal vapour is a strong function of the peak current density of the discharge.
However, seeds reached their peak density while still under the canopy of their parent.
In the modern era, it has a "period" somewhere between four to twelve years and a peak spectral density around five years.
On definition (a), the peak spectral density occurs at a frequency of 160.2 GHz, corresponding to a 1.873 mm wavelength.
A full 99 percent of the ingested calcium, whether through food or supplements, goes into the skeleton, which reaches its peak density at around age 30.
Zooplankton in the Canary Current reach their peak density in autumn when upwelling intensity decreases.
Voltage - the measure of the peak density of the steps (the highest density of arrows that ever appear on the screen at once).
The zebra mussels are Exhibit A. At peak densities, they outweigh all other organisms in their territory combined.
