(n.) Freedom from passion; moderation.
(n.) Condition with respect to heat or cold, especially as indicated by the sensation produced, or by the thermometer or pyrometer; degree of heat or cold; as, the temperature of the air; high temperature; low temperature; temperature of freezing or of boiling.
(n.) Mixture; compound.
Example Sentences:
(1) Carbon dioxide (CO2) levels, volumes, and temperatures of expired gas were measured from the tracheal and esophageal tubes.
(2) Spectral analysis of spontaneous heart rate fluctuations, a powerful noninvasive tool for quantifying autonomic nervous system activity, was assessed in Xenopus Laevis, intact or spinalized, at different temperatures and by use of pharmacological tools.
(3) The fraction of the viral dose which became cell associated was independent of the incubation temperature and increased with increasing target membrane concentration.
(4) These are typically runaway processes in which global temperature rises lead to further releases of CO², which in turn brings about more global warming.
(5) The high transition enthalpy for kerasin is ascribed to a lesser accommodation of gauche conformers in the hydrocarbon chains just below the transition temperature.
(6) From these data it is possible to predict theoretically the apparent temperature difference as seen by an infrared scanner or radiometer with a detector of which the spectral detectivity, D (lambda), is known.
(7) Augmentation of transformation response was generally not seen at 40 degrees C; incubation at that temperature was associated with decreased cellular viability.
