According to characteristics of gas deflagrations, this work developed a gas explosion temperature measurement system whose response time to temperature is approximate 10 μs.
Arrhenius-type ignition delay correlations were developed for temperatures greater than 1025 K which relate ignition delay time to temperature and concentration of the mixture.
The Tmax method used the time to temperature maximum while a novel temperature ratio method (TmRatio) used the ratio of the temperature maxima at the downstream and side probes.
The primary outcome of the study, time to maximum antipyresis, and the secondary outcome of time to temperature reduction by at least 1°C were analyzed by one-way ANOVA.
The continuous infusion regimen, however, was associated with a significantly shorter time to temperature normalization (1.2 ± 0.8 days versus 2.4 ± 1.5 days; P = 0.012) and a trend toward faster normalization of the white blood cell count (2.8 ± 2.4 days versus 3.9 ± 2.2 days; P = 0.065).
In the first 24 hours we recorded the time to temperature first falling below 37.2°C (fever clearance), the time spent without fever over 24 hours, and the proportion of children without fever associated symptoms: discomfort, reduced activity, reduced appetite, and disturbed sleep.
