A steady state analysis of the system driven only by a pump input amplitude ϵ reveals that below a critical threshold (|epsilon| < epsilon_{mathrm{th}} = frac{kappasqrt{kappa_{p}}}{4 chi}) the system as a unique fixpoint with (alpha_{s}=alpha_{i}=0) and (alpha_{p} = -frac{2epsilon}{sqrt{kappa_{p}}}).
This Schmidt law breaks down, however, at densities below a critical threshold value.
However, in order to avoid fast degradation, tars concentrations have to be below a critical threshold.
Rainfall intensity also increases surface resistance especially as the water depth diminishes below a critical threshold.
MEK uptake was precluded in epoxies whose Vh was below a critical threshold value of ∼68 Å3.
The data enables to estimate the contamination to be expected and to design methods keeping blanks below a critical threshold.
Once immunisation falls below a critical threshold within a population, "herd immunity" is lost and the virus is able to take hold and spread.
The commentary predicts it could be only two years before the number of floats drops below a critical threshold of 3,200, which would "considerably undermine the ability of the observing system to monitor and measure the global ocean".
Additionally, should the blood levels at a local hospital get below a critical threshold, the system automatically sends SMS alerts to the appropriate individuals at the centralized blood bank.
Half of the volunteer couples were treated according to the existing guidelines, with the infected partner being offered drug treatment only if his or her condition (as measured by the level of a particular immune-system cell in the bloodstream) dropped below a critical threshold, or if he or she developed actual symptoms of AIDS.
These tracks are only preserved at temperatures below a critical threshold temperature that is specific for each mineral.
