Techniques for high-accuracy straightness measurement, precision leveling, and absolute distance metrology are described, together with approaches to compensation for the effects of atmospheric refraction.
The benefits of the three-wire circuit include intrinsic bridge balance, automatic compensation for the effects of lead wire temperature changes on the bridge balance and increased measurement sensitivity compared to the two-wire configuration.
According to the authors, the reduction in PME activity may have been caused by compensation for the effects of over-expression, however down-regulation of PME and increase in stem elongation is consistent with the hypothesis presented here.
The economic benefits determined in this study for the CONTOUR® TS system may be more pronounced in clinical practice due to the additional benefits of the system, such as compensation for the effects of oxygen and maltose, which were not included in this analysis.
The LiCor Li6400 contains a barometric pressure sensor that allows for compensation of the effects of changes in partial pressure on measurements over a range of 65 115 kPa with an accuracy of and resolution of 0.002 kPa.
Neither the mean level nor the laminar distribution of COMT mRNA was related to the Val108/158 Met genotype, suggesting that the feedback regulation of mRNA level is not a compensation for the functional effect of the COMT polymorphism.
Counter-gradient patterns in thermal performance typically involve some form of metabolic compensation for the negative effect of thermal gradients on particular traits [20], [21].
Compensation for this effect is particularly important for accurate tumour activity quantification.
This illustrates why, even if all cases and all controls from a country are included in an analysis, structure can still generate false-positive associations unless there is compensation for the confounding effects of their unequal distribution.
