Midgard is situated halfway between Niflheim on the north, the land of ice, and Muspelheim to the south, the region of fire.
Tenability for the downstream region of fire is not the main focus of this research because vehicles can generally drive out of the tunnel at a higher speed than that of the smoke flow, and local damper smoke extraction can help keep a tenable condition in the downstream region beyond the local fire zone, in case there is a congestion in the downstream region of the fire.
In the investigated region of northern California, both the drought index and the regions of extreme fire risk have increased steadily since 1979.
DOM LC11 was shown to be more accurate than the commonly used S4 quadrature scheme, especially in anisotropic regions of the fire domain.
This led us to use double thermocouples to measure fluctuating temperatures in the continuous flame region of a fire plume.
Regions of both surface fire and crown fire were captured and are compared.
Profiles of mean and rms fluctuations are radially resolved across the fire plume, both within the hydrocarbon-rich vapor-dome region near fuel pool, and higher within the actively burning region of the fire.
Crown fire resulted in a significant increase in integrated radiative preheating, by a factor of ∼1.75, as well as greater flow sheltering in the downstream region of the fire front.
Within the actively burning region of the fire, soot is observed to occupy a limited temperature range between ∼1000 and 2000 K, with peak soot concentration occurring at 1600 1700 K across the full radial extent of the fire plume, despite marked changes in the local temperature pdf across the same spatial extent.
We also analyzed local services (for instance, the General Council of the Hautes-Alpes region, Regional Fire and Rescue Service, Police Center, Technical Regional Direction, National Forestry Authority) as we assumed that their local administrative level would be directly involved in crisis management.
The increased mRNA abundance was not greater at the regions of early origin firing (e.g., four origins are found in chromosome 10; OBR:10 0.80, OBR:10 1.25, OBR:10 1.92, and OBR:10 2.65; Figure 4), suggesting that it is not linked to replication.
