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.
Fireflies appear to light up for a variety of reasons. The larvae produce short glows and are primarily active at night, even though many species are subterranean or semi-aquatic. Fireflies produce defensive steroids in their bodies that make them unpalatable to predators.
