At least some accretion discs produce jets, twin highly collimated and fast outflows that emerge in opposite directions from close to the disc ( the direction of the jet ejection must be determined either by the angular momentum axis of the disc or the spin axis of the black hole ).

The primary advantage of the long-stroke system, beyond design simplicity and robustness, is that the mass of the piston rod adds to the momentum of the bolt carrier enabling more positive extraction, ejection, chambering, and locking ; Also as the gas is not directed back into the chamber the weapon stays cleaner longer thus reducing the likelihood of jams.

Thermionic emission occurs when the thermal energy exceeds the metal's work function, while field electron emission occurs when the electric field at the surface of the metal is high enough to cause tunneling, which results in the ejection of free electrons from the metal into the vacuum.

It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor as it transitions into the superconducting state.

As a result, about one third of the volume of the transient crater is formed by the ejection of material, and the remaining two thirds is formed by the displacement of material downwards, outwards and upwards, to form the elevated rim.

It is found that increasing the intensity of the incident radiation ( so long as one remains in the linear regime ) increases only the number of electrons ejected, and has almost no effect on the energy distribution of their ejection.

They may line the ejection channel, stopping the slime from sticking to the organism when it is secreted ; or they may slow the drying process long enough for the slime to reach its target.

A coronal mass ejection ( CME ) is an ejected plasma consisting primarily of electrons and protons ( in addition to small quantities of heavier elements such as helium, oxygen, and iron ), plus the entraining coronal closed magnetic field regions.

Critical events of Henry's reign are well described, including the dismissal of Peter des Roches ( after a politically loaded riddle by Roger Bacon is answered by Henry ), the ejection of Poitevins from England, the conflict with Hubert de Burgh, the marriage of Eleanor with Simon de Montfort, and finally the accession of Henry's son, Edward I after the battle of Evesham.

The ink system requires active solvent regulation to counter solvent evaporation during the time of flight ( time between nozzle ejection and gutter recycling ), and from the venting process whereby air that is drawn into the gutter along with the unused drops is vented from the reservoir.

So intense is the cold in this part of Tibet that these springs are sometimes represented by columns of ice, the nearly boiling water having frozen in the act of ejection.

The first 29 cantos of Aniara had previously been published in Martinson's collection Cikada ( 1953 ), under the title Sången om Doris och Mima ( The Song of Doris and Mima ), relating the departure from Earth, the accidental near-collision with an asteroid ( incidentally named Hondo, another name for the main Japanese isle where Hiroshima is situated ) and ejection from the solar system, the first few years of increasing despair and distractions of the passengers, until news is received of the destruction of their home port ( and perhaps of Earth ).

Ionization consists of the ejection of one or more electrons from the atom, and may occur if the atom is exposed to radiation with an energy greater than its ionization potential.

While a flintlock, for example, is immediately ready to reload once it has been fired, adopting brass cartridge cases brought in the problems of extraction and ejection.

These knives are set into the slots and covered in a compressible material, typically foam rubber, the function of which is the ejection of the cut puzzle pieces.

An often cited shortcoming of bullpups is that, by design, their ejection ports are close to the face, generally making it difficult for left-handed shooters to use because firearms in general have their ejection port on the right-hand side and eject spent cartridge casings towards the right.

Urination, also known as micturition, voiding, peeing, weeing, pissing, and more rarely, emiction, is the ejection of urine from the urinary bladder through the urethra to the outside of the body.

Douglas was a pioneer in related fields, such as ejection seats, air-to-air, surface-to-air, and air-to-surface missiles, launch vehicles, bombs and bomb racks.

Martin-Baker Aircraft Co. Ltd. is a manufacturer of ejection seats and safety related equipment for aviation.

His pistol was manufactured in three distinct variations ( differences related mainly to methods of spent cartridge ejection ) between 1867 and about 1880.

This movie shows the particle flow around the Earth as a coronal mass ejection strikes.

Electrospray techniques are used to control satellites, since the fine-controllable particle ejection allows precise and effective thrusts.

Upon ejection the kinetic energy of the Auger electron corresponds to the difference between the energy of the initial electronic transition and the ionization energy for the electron shell from which the Auger electron was ejected.

Thermionic emission occurs when the thermal energy exceeds the metal's work function, while field electron emission occurs when the electric field at the surface of the metal is high enough to cause tunneling, which results in the ejection of free electrons from the metal into the vacuum.

Often, instead of X-ray emission, the excess energy is transferred to a third electron from a further outer shell, prompting its ejection.

The bolt eventually reaches a velocity of zero and the kinetic energy from the recoil impulse is now stored in the fully compressed spring ( some energy loss does occur due to friction and the extraction and ejection sequences ).

However, one must expect that vaporization and ejection of material by hypervelocity impacts would cause a deviation from a linear relationship.

Rockets are used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight and exploration of other planets.

These ions, under the influence of the electric field, are accelerated into the cathode surface containing the sample, bombarding the sample and causing neutral sample atom ejection through the process known as sputtering.

This results in ejection of an ionised atom from the sample surface at a known time.

In August 1954, " Blues " leader LCDR Ray Hawkins became the first naval aviator to survive an ejection at supersonic speeds when his F9F-6 became uncontrollable on a cross-country flight.

# Motio (" removal ") or ejectio e senatu (" ejection from the Senate "), or the exclusion of a man from the ranks of senators.

Upon his ejection, Mr. Sianis uttered, " The Cubs, they ain't gonna win no more.

This in turn required the development of ejection seats so the pilot could escape and G-suits to counter the much greater forces being applied to the pilot during maneuvers.

: Cable locks are a popular type of chamber lock that usually threads through the breech and ejection port of repeating-action firearms ; they generally prevent full cycling of the action, especially preventing a return to " battery ", with the breech fully closed.

He associated himself with Presbyterianism, and was on the celebrated committee for the ejection of " scandalous and ignorant ministers and schoolmasters " during the Commonwealth.

In early 1942, prisoners at Dachau concentration camp were used by Rascher in experiments to perfect ejection seats at high altitudes.

The ejection was perceived by some as a particularly brutal action, and rumours circulated exaggerating its severity, though no evidence of anyone being killed in the course of it has come to light.

Recent work tries to take into account the roles of differences in parent bodies and the specifics of their orbits, ejection velocities off the solid mass of the core of a comet, radiation pressure from the sun, the Poynting – Robertson effect, and the Yarkovsky effect on the particles of different sizes and rates of rotation to explain differences between meteor showers in terms of being predominantly fireballs or small meteors.

* Inkjet printers, which use piezoelectrics or thermal bubble ejection to deposit ink on paper.

Also, note the spade grips, pintle mount and rapid cartridge case ejection.

The distinguishing features of this technology are the absence of ammunition feed and casing ejection systems ( the only moving parts are the projectiles ), and the electronic ignition of the propellant charges.
