The recent upsurge in placebo research has demonstrated the sound neurobiological substrate of a phenomenon once believed to be only patient mystification, or at best a variable to control in clinical trials, bringing about a new awareness of its potential exploitation to the patient's benefit and framing it as a positive context effect, with the power to influence the therapy outcome.
The signaling activity by airborne sound and substrate vibration of isolated males was continuously recorded during the night in a rainforest gap, at different times within the lunar cycle.
However, there is a risk of removing sound tooth substrate, when a tooth is treated by a restorative approach, while, the procedure for sealing is much less invasive.
The second simulation was for a two-layer medium consisting of a less elastic surface (20 μm thick) on top of the sound enamel substrate.
Behavioral responses were greater toward decayed pine substrates (UV-reflective) than sound pine substrates suggesting that decayed pine can be a useful foraging cue.
Insect pupae are generally considered inactive and quiescent, but some of them generate air-borne sounds and/or substrate-borne vibrations.
The results demonstrate that the use of the SiC + SiO2 powder mixture produces a severe damage on the base material, whereas the use of the SiC + Si mixture leads to the formation of sound coatings without substrate damage.
The contradictory high vapour permeability and low sorptivity of Lithomex, presumably attained using specific additives, highlights the need for a sound understanding of substrate material.
From our results it was not possible to determine explicitly whether the vibrational signals were detected as air-borne sound or as substrate vibrations induced in the leaf.
Afferent activity of receptors either sensitive to air-borne sound or to substrate vibration was therefore recorded under natural noise conditions in the respective transmission channel, and the reliability of detecting the signal determined.
The speed of sound in LiNbO3 substrate is approximately 3900 m/s, leading to a resonant frequency around 13 MHz.
