Associate degrees, which usually require two years of study, provide a broad base in general education as well as a specific concentration.
But carbon dioxide has been in a specific concentration in our atmosphere -- within the range of 170 to 300 parts per million -- for 800,000 years.
Although we set the counterfactual concentration to be drawn from a uniform distribution with a lower bound of 5.8 μg/m and an upper bound of 8.8 μg/m, we are not suggesting that there is convincing evidence that PM2.5 mortality and ALRI risk is zero below any specific concentration based on biological considerations (Brook et al. 2010).
Alternatively, PrPSc accumulation might proceed in animals inoculated with PrPSc when the PrPSc concentration is below a specific cut-off, but the animals might not develop the disease within their lifetimes.
Recent measurements in the terra firme Amazonian rain forest provide evidence that more short-chain aldehydes and the corresponding organic acids were taken up from the air than produced, although release was observed when ambient concentrations were below a specific level (Rottenberger et al., 2008).
There is no specific concentration of CK above which renal impairment definitely occurs; concentrations below 20,000 U/l are unlikely to be associated with a risk of renal impairment, unless there are other contributing risk factors.
Electronic devices are required to operate below a specific temperature for functionality and high reliability.
For example, to turn on a heater, the temperature should be below a specific threshold.
Training procedure continues until an amount of increase in likelihood falls below a specific threshold.
This result is in accordance with data from a screening study in Gothenburg, Sweden, in which no man with a prostate specific antigen concentration below 1.0 ng/ml was diagnosed as having prostate cancer during three years of follow-up.
