The method requires the measurement of the storage modulus (G′) and the loss modulus (G″) at a certain frequency (w) by oscillating viscosity measurements.
The gelation of different carrageenans in aqueous solutions was investigated by ultrasound at 7.8 MHz and by oscillating rheological measurements.
However, the gelation of ι-carrageenan, which could be detected by the oscillating rheological measurement, did not cause detectable changes in the ultrasonic measurement.
The resulting diamond-like carbon (DLC) films were characterized tribologically by nanoindent hardness measurements, oscillating ball-on-disc friction and wear tests as well as impact and scratch adhesion tests.
A first set of measures has been performed during the steady state, allowing the study of the new discovered property calledsound intensity polarization, which accounts for the amount of energy oscillating thorugh the measurement point.
Further, lower crosstalk between topography and potential images in HAM-KPFM compared to that in FM-KPFM is due to the first and second resonance signals being separated from each other using low- and high-pass filters in HAM-KPFM; on the other hand, the potential and topography signals are difficult to separate because the first resonance of the cantilever was oscillated in both measurements.
For the PM2.5 surface, we computed the annual geometric average for 2002 from 14 Ministry of the Environment of Ontario (MOE) stations, equipped with tapered element oscillating microbalance monitors (hourly measurements).
Fat has multiple spectral components, and this single measurement of T2 decay curve is not adequate (such a measurement yields oscillating signal behavior) (16).
This is because the method produces an unbiased (Todd et al. 2002) point estimate of the true concentration that oscillates, because of measurement uncertainty, around the true bone lead concentration.
After the laser is turned on the transmission intensity rises up to line B and then rises for the second time to line A. Afterwards, the measurement oscillates only between the two lines.
