They said the F.B.I. harassed the defendants after some of them were spotted in rural Virginia playing "paint ball" -- a game in which players use pressurized guns to shoot capsules of paint at each other.
Start with storing hydrogen as a highly pressurized gas, which raises safety concerns.
The "Fruitcake Launch", a separate competition held on the same day, allows contestants to use mechanical devices, pressurized air guns and cannons to launch a two pound confection across an empty field in hopes of earning the coveted trophy and bragging rights for farthest travelling fruitcake.
Unusual features of these mechanisms include the controlled and rapid rupture of the pressurized squirt guns that allow the nearly instantaneous release of energy and discharge of the spores and sporangia.
Particles were delivered to RGCs from a helium-pressurized gun (BioRad) at approximately 40 psi (Morgan and Kerschensteiner, 2011).
Mechanisms include a catapult energized by surface tension that launches mushroom spores, the explosive eversion of a pressurized membrane in the artillery fungus, and the discharge of squirt guns pressurized by osmosis [7].
Mud volcanoes appear when sediments like silt and clay become pressurized by hot gas trapped underground.
After using pulse lavage, vacuum-mixed cement was injected directly from the cement gun and the cement was pressurized by a seal.
Other physical methods can also be used to increase in vivo gene transfer, including pressurized vascular delivery, laser, magnetic fields and gene gun delivery.
Because the gas is naturally pressurized, pumps are not needed to bring it to the surface.
A root Rx uses an air-spade gun to till the soil with highly pressurized air and mix in nutrients to create a potting medium without hurting fine roots.
