For a concentration close to zero, the value of the flux should be close to zero as well.
However, in the subgroup without asthma, the effect of flued versus unflued gas heater exposure on eNO concentrations was close to zero [0.03 ppb (95% CI, −0.68 to 0.74), p = 0.93].
In the early stage of the transport experiment, the HDTMA effluent concentration was close to zero while the counterion Br− concentration was about 50% of the input concentration, indicating a complete removal of HDTMA but only a partial removal of bromide.
Because XRF measurement of bone lead concentration can, due to measurement uncertainty, produce negative point estimates when the true bone lead concentration is close to zero, in our analysis, we kept all point estimates (including negative values) of bone lead concentrations, which yields less bias and more efficient comparisons (Kim et al. 1995).
From the experimental analysis, we noted that, as the sAMS concentration increases to a large value (~103 μM), the measured relative cell concentration becomes close to zero [ 53].
For the latter, the cation concentration is close to zero.
Apparent reaction order with respect to SO2 concentration was close to zero when attrition was taken into consideration.
In this case, the computed value of the Patent Blue V concentration is close to zero.
Using concentrations close to their IC10 IC20 values, combination of the three drugs showed strong synergistic cytotoxicity.
In order to experimentally confirm LoQ, six standard solutions with concentrations close to the LoQ were prepared and analysed.
