Computers A garbled communication between 2 devices in a local area network (LAN) that results when both attempt to transmit data simultaneously; after colliding, each device waits for a period of time and retries; increased devices on a LAN increase the likelihood of collision
Obstetrics A mechanical obstruction to the birth of twins, such that the lay of one foetus impedes the engagement of the other; the most extreme collision is known as interlocking
Public health Road traffic accident/motor vehicle accident
Radiation physics The interaction between 2 particles—e.g., photons, atomic nuclei, electrons—during which energy, momentum, and charge may be altered

collision

Obstetrics A mechanical obstruction to the birth of twins, such that the lay of one fetus impedes the engagement of the other; the most extreme collision is known as interlocking, see there Public health Motor vehicle accident. See MVA.

As mentioned above, in order to account for the behavior of several ions in the Second Solar Spectrum, collisional depolarization mechanisms have been invoked (see [72] and references cited therein).
Generalized dispersion equation is obtained at arbitrary inclination angles of both external magnetic field and wave vector of an incident EM waves in the turbulent collisional magnetized plasma.
From their analysis, it is concluded that the compression and heating of the gas due to the presence of high-velocity flows can directly affect the chemical abundance determinations due to: (a) an overestimation of the collisional de-excitation effects on emission lines arising from levels with low critical densities; and (b) the use of too high [T.sub.e] values for deriving abundances due to contamination from emission of the leading working surface.
Collisional evolution refers to changes in the size and number of asteroids as collisions repeat over time.
In this presentation, we will present the first experimental evidence supporting the use of such models for weakly collisional plasmas which are relevant to various space and astrophysical plasma environments.
The plasma is assumed to be homogeneous, steady-state and collisional. The thickness of the plasma is d, which is set to 45 mm in the following numerical simulations.
The quenching takes place through a collisional process and also by ground-state complexation between fluorophore and quencher molecules (5).
This difference becomes larger as the energy of the proton beam is increased, which means that it subsides towards the ends of proton tracks, where nuclear elastic scatterings that give rise to atomic displacements become more probable than electronic collisional events.
The timing of the eruptions and pooling the plutons mostly coincides with and postdates a series of continental collisional events in the northern Bitlis-Zagros Suture Zone region [1, 2].
