(15) In these patients, left ventricular mass seems to be greater in non-dippers than in dippers among women, but not in men.
(16) However, a second pattern of a dipper-type swallow occurred, in which part of the bolus initially is positioned beneath the anterior part of the tongue.
(17) Strong evidence suggests that the NNN and NNK in snuff are at least partially responsible for the excess of oral cancer among snuff dippers.
(18) "Reverse"-cigar smokers (who hold the burning end of cigars within the mouth), dippers (who place a mixture of Khaini-tobacco and slaked lime into the lower gingival groove) and users of tobacco-containing toothpaste (gudakhu) in Orissa, India, were examined for precancerous oral lesions, the frequency of micronucleated cells at 3 different intra-oral sites, and levels of tobacco-specific nitrosamines (TSNA) in the saliva.
(19) The apparatus consisted of an enclosure with two levers, two loudspeakers (in different locations), and a dipper feeder.
(20) Rats were trained on a multioperant baseline to respond on three different levers that resulted in either a food pellet, the presentation of a water dipper or an infusion of morphine.

Definition:
(n.) One whi sips.
Example Sentences:
