The fi nal product of a post-volcanic activity is the exhalation of a low-temperature (<100°C) deep origin mofette gas, which contains mostly carbon dioxide. Examples of mofettes are the Torjai-Büdös cave in Transylvania, Romania [1] or the CO2 seepage in Mátraderecske, Hungary [2]. The term ‘mofette’ derives from the Latin word ‘mephitis,’ which means smelly exhalation [3]. Along its path to t...

Speech and variation of respiratory chest circumferences of eight French dyads were monitored while reading texts with increasing constraints on mutual synchrony. In line with previous research, we find that speakers mutually adapt their respiratory patterns. However a significant alignment is observed only when speakers need to perform together, i.e. when reading in alternation or synchronousl...

AIM To test the hypothesis that complications of neonatal intensive care are related to increased oxygen derived free radical activity, using breath pentane as a marker of lipid peroxidation. METHODS Exhaled breath was collected daily from 57 ventilated preterm infants and pentane concentration measured by gas chromatography. RESULTS High peak pentane exhalation was significantly associated...

Objectively assessing respiratory health in longitudinal social science surveys would involve collecting pulmonary function measures on research participants, either in clinic settings or at home. These measures include indicators of volume (e.g., maximal amount of air blown in the first second of a forced exhalation) and airflow (maximal speed air is exhaled during a forced exhalation). Equipm...
