BACKGROUND Wet swallows cause a greater esophageal contraction amplitude and duration than dry swallows. In Chagas' disease there is a reduction in amplitude of esophageal contraction but we do not know if the difference between wet and dry swallows is seen in the disease. AIM To compare the esophageal contractions after wet and dry swallows in patients with Chagas' disease. METHODS We meas...

The objective of the study was to determine the influence of simulated microgravity by exposure to dry immersion on the craniomandibular system. Twelve healthy male volunteers participated in a 3-day dry immersion study. Before and immediately after exposure we measured maximal bite force using piezoresistive sensors. The mechanical properties of the jaw and cervical muscles were evaluated befo...

A dry clutch model with thermal dynamics is added to a driveline model of a heavyduty truck equipped with an automated manual transmission. The model captures driveline oscillations and can be used to simulate how different clutch-control strategies affect vehicle performance, drivability and comfort. Parameters are estimated to fit a heavy-duty truck and the complete model is validated with re...

already conversant with the author's writings that it is characterised by wide erudition and a marked historical sense, and written in the racy and incisive style which we expect from him. The book is practically a compendium of the history of medicine, and without being unduly condensed, and in consequence dry, it is yet remarkable for the amount of information which is contained within the co...

OBJECTIVE To determine the economic burden of malaria in a rural Tanzanian setting and identify any differences by socioeconomic status and season. METHODS Interviews of 557 households in south eastern Tanzania between May and December 2004, on consumption and malaria-related costs. RESULTS Malaria-related expenses were significantly higher in the dry, non-malarious season than in the rainy...
