Mr. Palmieri said it appeared that a lack of reactive power, measured in what are known as VAR's, led to low voltage on transmission lines and threatened the stability of the system.
The EndoPAT system (endothelium pulse amplitude tonometry) will be used to give a measure of Reactive Hyperemic Index (RHI), a measure of endothelial function designed to be used in conjunction with FMD measurement of reactive hyperemia.
In addition, the production of reactive oxygen species measured by 3,3′-diaminobenzidine (DAB) staining was significantly decreased in transgenic cultured cells under salt stress.
Partial pressures of reactive gases are measured by differentially pumped mass spectrometers or by optical emission spectroscopy (OES), optical emission monitoring (OEM), and plasma emission monitoring (PEM).
The signal intensity of reactive bands was measured with a phosphorimager (GS-710, Bio-Rad, Hercules, CA, USA).
Finally, mean levels of reactive oxygen species measured in vivo showed a significant non-linear relationship with ND5 deletion level, a pattern that may be driven by among-isolate variation in antioxidant or other compensatory mechanisms.
The study sample size determination was based on data from a previous study by Harris et al. who enrolled nine patients to detect an increase of reactive hyperemia, as measured by flow-mediated dilation of the brachial artery, immediately after 45 min of exercise on a treadmill at 50% of their VO2 peak.
Obese individuals have demonstrated markers indicative of oxidative stress, including elevated measures of reactive oxygen species (ROS) [2] and diminished antioxidant defense, which is associated with lower antioxidant enzymes [3].
The RPQ [ 12, 14] includes 23 items that were based on previous teacher-rating measures of reactive aggression and proactive aggression, and on conceptual and theoretical relevance.
Both the TNBS assay and modified Ellman's test measure the number of reactive functional groups and are a measure of "hapten equivalences" and not hapten density per se.
