Water gels that are cap-insensitive are referred to under United States safety regulations as blasting agents. Water gel explosives have a jelly-like consistency and come in sausage-like packing stapled shut on both sides. [2] Water-gel explosives have almost completely displaced dynamite, [citation needed] becoming the most-used civil blasting ...
An example of a social trap is the use of vehicles and the resulting pollution. Viewed individually, vehicles are an adaptive technology that have revolutionized transportation and greatly improved quality of life. But their current widespread use produces high levels of pollution, directly from their energy source or over their lifespan.
In espionage, a sleeper agent is one who has infiltrated the target country and has "gone to sleep", sometimes for many years. The agent makes no attempt to communicate with the sponsor or any existing agents or to obtain information beyond what is public, and becomes active only upon receiving a pre-arranged signal or message from the sponsor or a fellow agent.
Once lowered and latched on the wellhead, a capping stack uses stored hydraulic pressure to close a hydraulic ram and stop the flow of hydrocarbons. [33] If shutting in the well could introduce unstable geological conditions in the wellbore, a cap and flow procedure would be used to contain hydrocarbons and safely transport them to a surface ...
The government's estimates suggested the cap and other equipment were capturing less than half of the oil leaking from the sea floor as of late June. [24] On July 10, robots removed the containment cap to replace it with a better-fitting cap ("Top Hat Number 10"); this meant all of the leaking oil would escape until the new cap was in place. [25]
In-situ capping has been effective in numerous locations. For example, in several places in the interior of Japan “in-situ capping of nutrient-laden sediments with sand” has worked very well in preserving water quality by reducing “the release of nutrients (nitrogen and phosphorus)” and oxygen depletion by bottom sediments.

Capping may refer to: the creation of five-prime (5') caps in a cell nucleus Capping enzyme; Cap (sport), making an appearance in a game at international level; Ambulance chasing, the practice of lawyers seeking clients at a disaster site; Jakugo, or capping phrase, a response to a Zen kōan; Capping stunt, a New Zealand university student prank
The attachment of these capping/stabilizing agents slows and eventually stops the growth of the particle. [5] The most common capping ligands are trisodium citrate and polyvinylpyrrolidone (PVP), but many others are also used in varying conditions to synthesize particles with particular sizes, shapes, and surface properties.
