The phrase "a range of pm" is not entirely clear in its context, but it is grammatically correct and can be used in written English.
You can use it when referring to a variety of time periods or specific times in the afternoon or evening, typically in a scheduling or planning context.
Example: "The meeting is scheduled to take place between a range of pm, from 2:00 to 4:00."
Alternatives: "a variety of pm" or "a selection of pm".
As a result, the current increased linearly with the miRNAs concentration over a range of 10 fM–5 pM, and a detection limit of 3 fM was achieved.
We computed the sensitivity and specificity for a range of threshold PM values and plotted the ROC curve i.e. sensitivity versus (1 - specificity) (see Figure 10).
By invariant, we mean that there exists some ranking number n such that all positions with ranking higher than n retained a ranking higher than n (independent of order) over a range of PD, PM and the leave-one-out analysis.
The study was designed to evaluate a range of ambient PM concentrations.
In the present work, we investigated short- and long-term effects of particle exposure on DNA methylation in peripheral blood DNA from workers with well-characterized exposure to a wide range of PM levels in an electric steel furnace plant.
Although we were able to enrich the concentration of PM 6- to 8-fold, variation in ambient levels resulted in a wide range of PM exposures between 50 and 682 μg/m.
The marked changes of PM air pollution before, during, and after the Beijing 2008 Olympic Games provided a unique opportunity to investigate the effect of a wide range of PM exposure on cardiac autonomic function.
These cells were suspended in RPMI 1640 culture medium containing a range of concentrations of PM-17.
In the present study on foundry workers exposed to a wide range of PM levels, we investigated the association of blood MtDNAcn with exposures to airborne PM and its metal components.
Similar relationships have been reported in locations reflecting a wide range of PM and of gaseous copollutant concentrations (Goldberg et al. 2001; Koken et al. 2003; Linn et al. 2000; Sunyer et al. 2003; Zmirou et al. 1998).
