Technology Overview. Rammed Aggregate Piers are a patented/proprietary ground improvement system that uses compacted aggregate to create stiff pier elements. The installation process modifies the soil surrounding the piers.
Foxfire, also sometimes called fairy fire, is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to luciferase, an oxidative enzyme, which emits light as it reacts with luciferin.
Hot objects glow and give off light, just as the coils of a toaster glow red, or the wood and coals of a fire give off light. The colors of a flame actually indicate the local temperature of the gases. At temperatures above 1000 oF objects will glow and give off visible light that we call incandescent. This thermal radiation has only a small portion in the visible (about 5% for a fire) while most of the rest is infrared radiation. You can feel infrared radiation as the heat from a fire. Thermal radiation is the name for electromagnetic radiation emitted by the huge numbers of electrons in hot objects and as such, if the wavelengths of the light are examined, there is a continuous distribution of all wavelengths or frequencies present.
