Ambient air concentrations are most often reported as an average concentration measured over an 8 h, 24 h or longer duration.
Cellulase production by brown rot fungi is different in that it is typically constitutive, not influenced by free glucose concentrations, and most often lacks exo-acting cellobiohydrolase [ 22, 23].
While concentration is most often presented, it has been suggested that load may more accurately describe the burden of exposure [ 24].
In the study of Hardarson et al. [ 13] the Mn concentration was also high in the Vestfirðir Peninsula, the Snæfellsnes County, the Dalir County and Areas IV and VII (on average 140-185 mg kg-1) whereas the Mn concentration was most often lower in other regions.
7, 8 E-R analysis, in its broad definition, includes PK/PD modeling as a special case where the exposure variable is drug concentration, but most often the term E-R refers to analyses that differ from PK/PD models in several aspects: I) The exposure variable is a summary variable such as area under the curve (AUC), rather than the concentration timecourse.
The concentration of polyisocyanates, most often HDI, varies from 40 to 95% depending on the manufacturers and the product lines.
The concentration of capsaicin most often used (1.6 mM) was obtained by a 10 times dilution of the 16 mM solution with physiological saline.
In the vast majority of these cases, vegans had the lowest concentration, whereas meat eaters most often had the highest concentrations of the acylcarnitines, glycerophospholipids, and sphingolipids, and fish eaters or vegetarians most often had the highest concentrations of the amino acids and a biogenic amine.
For the vast majority of these metabolites, vegans had the lowest concentrations and the meat eaters most often had the highest concentrations.
Third, the military wings maintain their own penal administration and control a network of detention facilities (most often concentration camps).
