Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The ratio of the pressure over an imaginary surface in a sound wave to the rate of particle flow across the surface.
- ‘The harmless waves are aimed at the part to be examined, and reflections are detected from tissue components in proportion to their acoustic impedance.’
- ‘From the acquired measurements of sound speed and acoustic impedance, the important physical properties of in situ density and adiabatic compressibility could be calculated.’
- ‘Dipping energy of the strength portrayed by the ILP lines must represent parallel layers of contrasting acoustic impedance.’
- ‘Signal processing procedures have been developed that estimate acoustic impedance and compressional wave attenuation with depth beneath the sea floor.’
- ‘These invariably cause seismic waveform scattering and degeneration as a result of factors such as surface geometry and acoustic impedance contrasts through the lavas.’
We take a look at several popular, though confusing, punctuation marks.
