(17) IJPs disrupt the regular pattern of myenteric potential oscillations.
(18) The oscillations displayed a period averaging 9 minutes.
(19) The effect of the drugs on respiratory resistance (Rrs), measured using a forced oscillation technique, was measured both before and after the inhalation of a dose of capsaicin which caused less than two coughs.

Reverberation
Definition:
(n.) The act of reverberating; especially, the act of reflecting light or heat, or reechoing sound; as, the reverberation of rays from a mirror; the reverberation of rays from a mirror; the reverberation of voices; the reverberation of heat or flame in a furnace.
Example Sentences:
(1) The reverberation times were 2.1 and 1.6 s. In quiet conditions at normal speech level (60 dBA), the perception was better without earmuffs than with them.
(2) In addition, several cells showed unusual firing patterns, such as delayed responses and reverberating afterdischarges.
(3) The proposed physical process by which the metaorganization principle is implemented is based on oscillatory reverberation.
(4) The fact, that following the cooling or ablation of the auditory cortex the rhythmic afterdischarge to sound clicks as well as spontaneous spindle bursts keep arising in the medial geniculate body without changing their patterns, militates also against the possibility of thalamocortical reverberation.
(5) In situations with reverberation and less background noise the difference is less marked.
(6) For the reverberant condition, the sentences were played through a room with a reverberation time of 1.2 s. The CVC syllables were removed from the sentences and presented in pairs to ten subjects with audiometrically normal hearing, who judged the similarity of the syllable pairs separately for the nonreverberant and reverberant conditions.
(7) The fossil fuel resistance, like the fossil fuel industry, is protean and sprawling – and each win reverberates for decades to come, because that’s how long pipelines and coal mines are built to last.
(8) There are reverberating circuits between the fundus caudati and the medial groups of the nigra characterized by their small cells, between the putamen and the postero-lateral cell groups of the nigra, between the caudatum and the rostral cell groups of the nigra, presumably with the specialization that the lateral caudatum is in two-way connection with the rostro-lateral cell groups of the nigra as is the medial caudatum with the rostro-medial cell group.
(9) Speech recognition was assessed under three levels of room reverberation, each in quiet and noise, for subjects with varying amounts of sensorineural hearing impairment.
