The phrase "a common concentration of" is correct and usable in written English.
It can be used when discussing the typical amount or level of a particular substance or element found in a specific context, such as scientific or environmental discussions.
Example: "In this region, there is a common concentration of nitrogen in the soil, which supports the growth of various plants."
Alternatives: "a typical level of" or "a frequent amount of".
The titration experiment showed that the cisplatin concentration and the fluorescence signal change ratios (F0/F) exhibited a consistent linear correlation within the 1 to 10 μM range with a limit of detection of 720 nM, which was even lower than the common concentration of cisplatin in chemotherapy patients' urine (54.3 to 321 μM).
But a new experiment has shown that fairly common concentrations of ozone, the eye-stinging ingredient in smog, can sharply impede this process.
Iodine concentrations in soil ranges from 0.5 40 μg/g with common concentrations of 1 5 μg/g, a value much greater than that of underlying rocks (0.05 0.5 μg/g; Fuge et al., 2005; Hou et al., 2009b).
C content was not measured directly, but if we assumed similar levels to previous studies (e.g. Rytter [18] used a common C-concentration of 500 mg g−1 biomass [62]) we can derive C accumulation levels in the crop of 0.79 1.17 t ha−1 year−1 below ground and 5.21 6.93 t ha−1 yeaboveabove ground, with the greatest potentials for both pools being in Endurance.
8 This is a subtle but important issue that CytoSolve is aware of, which becomes apparent during the Controller's evaluation of a common species concentration, across a set of models.
Gini coefficient is a common measure of concentration that varies from 0 to 1.
A common time-pattern of concentration change during recovery was revealed for the two M2 specific cytokines, TGFβ1 and IL-10: concentrations in the medium at day zero were significantly higher (p < 0.01 for IL-10, and p < 0.001 for TGFβ) than in the medium from controls, which suggested that microglia release these cytokines during OGD.
Ronald S. RonoNietupskipski, MBA'67, recently received the Coleman Foundation/DePaul University inventor/invention of the year award for his product QUIT'M, an inhaler that contains a formulated concentration of a common food flavorant that makes cigarettes taste bad.
