For 10Be, the limit of detection in terms of the isotopic abundance ratio 10Be/9Be is 6 × 10−15 at at−1 and the total efficiency of counting atoms in the sample cathode is 1/8500 (0.012%).
For each published meta-analysis, as a measure of the efficiency of the method, we counted the number of articles selected at each threshold and compared this with the number of articles screened by the authors of the meta-analysis.
In this study, the HML has simulated the respiration motion using a 4D non-uniform rational b-spline (NURBS -based Cardiac-Torso (NURBS -basedm and determined the impact of that motion on the counting efficieNCATof their lung counting system during measurement.
Perhaps most impressive is the efficiency of the stewarding - count all those slack-jawed bystanders in luminous bibs enjoying the spectacle but refusing to get involved.
Wages amount to just 20% or so of a car's cost; the efficiency of the supply chain counts for a lot more.
The counting efficiency of incorporation of [H]glucose was determined to be ∼50% by using internal standards.
Additionally, diffusion losses in the whole system (including the neutralizer) are considered via the 'effective length', as well as the counting efficiency of the CPC in particular with respect to their lower cut-off diameters50.
Preconditioning the polydisperse sample using a thermodenuder at 100 or even 250 °C slightly increased the counting efficiency of the N-WCPC, but this still remained below the counts of the butanol CPC.
The test results show that the counting efficiency of 0.3μm gear is above 70%, 0.5μm gear and 1.0μm gear are both reached more than 90%, and the dispersion coefficient of each gear is very nearly the same, compared with the standard machine of Kanomax 3886 under the particle spraying flow of 2.5SCFH, 3.0SCFH, 3.5SCFH.
The Human Monitoring Laboratory (Canada) has looked at parameters (lung volume, lung deposition pattern, etc). that can affect the counting efficiency of its lung counting system.
