Sentence examples for depopulation rate from inspiring English sources

For states with values of n close to 30, photoionisation accounts for approximately 8%% of the blackbody-radiation induced depopulation rate in a 300 K environment [18, 106, 121].

After summing the transition rates to all neighbouring Rydberg states, the total blackbody depopulation rate for H atoms in the absence of external fields at n=30 can be determined to be ∼12 400 s −1 which corresponds to a time constant of ∼80 μs.

Under the assumption that approximately one third of the blackbody-radiation-induced transitions are Δ M J =−1 transitions one can conclude that ∼33%% of the blackbody-radiation-induced depopulation rate results in trap loss, leading to an expected decay time greater than 100 μs.

However, while the overall blackbody depopulation rates of the initially prepared Stark states are expected to be similar to those for H or D, the effects of these transitions on the decay of the H2 molecules from the trap are different.

After a decade of high unemployment rates and depopulation, the city's proximity to the Hibernia, Terra Nova and White Rose oil fields has led to an economic boom that has spurred population growth and commercial development.

Here, the rise of the grey singleton is blamed on the breakup of the extended family, rural depopulation and the rising divorce rate among middle-aged and retired couples.

The weak emission intensity from these Chls b prevents accurate estimation of the rate of their depopulation.

Assuming that only nonradiative and radiative processes are essentially involved in the depopulation of the 5D0 state,η can be defined by radiative transition rate (Ar) and nonradiative transition rate (Anr) [39], Ar can also be obtained by summing over the radiative rates A0J for each 5D0 → 7F J JJ = 0 4) transitions of Eu3+.

The structural problems were evident then to sociologists at Wayne State University in 1963, who predicted the depopulation precisely and sadly the way it happened, with the city losing productive taxpayers at the rate of a half-million per decade.

If these replacement bees die at a rate that exceeds the colony's ability to replace them, the result would be rapid depopulation, a reduction in the bee-to-brood ratio, and eventually colony failure.

Control policies based on flock depopulation (such as in Period I) are expected to have a direct impact on the effective within-flock contact rate while control involving depopulation plus preventive vaccination of flocks (such as in Period II) will contribute with the added impact on the properties of the natural history of infection.
