It can be used in contexts discussing the release or production of substances, such as gases or sounds, in a specific manner or environment.
Example: "The pollutants are emitted in a controlled manner to minimize environmental impact."
Alternatives: "are released in a" or "are discharged in a".
Field emission displays (FEDs) are based on the idea that electrons are emitted in a grid, rather than from a single source as in a television.
These vibrating molecules heat up and create a burning sensation, akin to touching a hot light bulb.The microwaves are emitted in a tight beam that can be swept across a crowd or directed at specific individuals.
The diffracted X-rays are emitted in a 2θ cone and collected on the imaging plate, from which the diffractogram is extracted.
The theory describes the particles that make up ordinary matter: the electrons that whiz around in atoms, the up quarks and down quarks that make up the protons and neutrons in atomic nuclei, the neutrinos that are emitted in a type of radioactivity, and two sets of heavier cousins of these particles that emerge in particle collisions.
The calls are emitted in a variety of stressful circumstances such as presence of humans, falling trees, terrestrial predators, and after aggression between group members.
While some signals, like many morphological ornaments, are always "on," most signals like song, advertisement calls, and motor displays are emitted in a way that optimizes transmission to intended receivers [1].
These lines can only be emitted in a high vacuum.
It is assumed that the intervals are so small that the probability of two or more particles being emitted in a single interval is negligible.
Photons also can be emitted in a free state, in which case they may be observed as light or other forms of electromagnetic radiation.
Reanalyzing data beamed back a quarter century ago by the Viking lander, Dr. Joseph Miller of the University of Southern California concluded that gases from the soil were emitted in a cyclical manner resembling the circadian "day-night" rhythms of living creatures on earth -- adjusted for the length of the Martian day, 24.66 hours.
By July 1943 two essential and encouraging pieces of experimental data had been obtained plutonium did give off neutrons in fission, more than uranium-235; and the neutrons were emitted in a short time compared to that needed to bring the weapon materials into a supercritical assembly.
