Sentence examples for time using calibration from inspiring English sources

The column pressure was set at 8.22 p.s.i., and the initial flow rate was 1.0 ml per min. The molecular structures of VOCs were determined by a spectral library match (and not by retention time using calibration mixtures) using the standard modular set.

We chose the delta-delta Ct method [ 9] for real-time PCR measurement rather than using calibration curves.

As a result we also estimated divergence times using a relaxed molecular clock using calibration points based on best estimates of divergence times in the fossil record for Bison and Yak (2.0 and 1.7 MYA, respectively).

AMS (Accelerator Mass Spectrometry) radiocarbon ages were determined by the BETA Analytic Laboratory and are corrected for variations in atmospheric CO2 reservoirs over time using the SHCal13 calibration (Hogg et al. 2013).

Although it is possible to acquire CCS values directly from drift-times using conventional IMS [27], calibration of the travelling-wave IMS device with ions of known CCS is required [28 30].

For this, we combine sequence data of the Telmatherinidae with data of representatives of the Melanotaeniidae, the closely related rainbowfishes from Australia and New Guinea [ 22- 25], and estimate divergence times using both indirect and geological calibration points, and substitution rates suggested by [ 24] as telmatherinid fossils are missing.

This can be exploited to directly calculate substitution rates and divergence times using the sampling age as tip calibration in a Bayesian framework analysis.

In turn, these three time estimates were used as calibrations for estimating other divergence times using least-squares and penalized likelihood methods, and the 95% confidence intervals were used as nodal constraints for the Bayesian analysis.

The concentrations of doxorubicin throughout the releasing time were calibrated using the calibration equation.

PBGD and onfFN transcripts of 18 FTC and 48 PTC samples were then quantified by real-time PCR using the calibration curve made of diluted cloned controls.

The results in Table 4 imply that our inference differs considerably from the calibration times used by Yoder et al. All times inferred by us on the Laurasiatheria clade (C4 C7) are wildly underestimated as compared to the reported calibrations, although the relative edge lengths on the clade seem to agree.
