The volume of fat, alveolar ventilation rate, cardiac output, and blood/air partition coefficient were sampled according to informative prior distributions (Table 3).
Table 2 illustrates that system A showed best partition coefficient in all the three systems of PEG/ potassium phosphate.
Therefore, the effect of partition coefficient on sorption capacity of the materials is dominant under the conditions of the same inlet concentration and same material volume.
Sevoflurane has an onset time of 2 minutes, and, due to a low blood-gas partition coefficient (0.
For each anaesthetic (halothane, sevoflurane and isoflurane), a comparison was made between pregnant and non-pregnant rats for the blood/gas and tissue/gas partition coefficient for each of the tissues (brain, liver, kidney and heart), testing with the unpaired-samples t-test and corrected for multiple comparisons by the Bonferroni method.
Note that because the REE partition into apatite, the proportion of apatite precipitating must be large enough to remove P but small enough to keep the bulk partition coefficient for the REE less than one because their concentrations increase with differentiation.
Based on the fitted models, we evaluated the "variance partition coefficient (VPC)," which represents the fraction of the total residual variation that is due to the MCO level (Goldstein, Browne, and Rasbash 2002).
For the description of ozonation processes in a three-phase system gas/water/ solvent it is necessary to know the solubility coefficient of ozone in each of the liquid phases as well as its partition coefficient between the phases.
