EE accompanies the relaxation of these unequilibria. The relaxation can be stimulated e.g. by slight heating or longwave illumination, not causing emission from untreated samples. Accordingly, thermo and photostimulated EE TSEE, PSEE are distinguished. Thus, EE is an electron emission analogue of such optical phenomena as phosphorescence , thermo and photostimulated luminescence .

Proton emission also known as proton radioactivity is a type of radioactive decay in which a proton is ejected from a atomic nucleus nucleus . Image Zerfallsschema.png left thumb 300px The decay of a proton rich nucleus A populates excited states of a daughter nucleus B by emission or electron capture EC . Those excited states that lie below the separation energy for protons Sp decay by emission towards the groundstate of daughter B. For the higher excited states a competitive decay channel of proton emission to the granddaughter C exists, called delayed proton emission. Proton emission can occur from high lying excited states in a nucleus following a beta decay , in which case the process is known as beta delayed proton emission, or can occur from the ground state or a low lying nuclear isomer isomer of very proton rich nuclei, in which case the process is very similar to alpha decay . For a proton to escape a nucleus, the proton separation energy must be negative the proton is therefore unbound, and Quantum tunneling tunnels out of the nucleus in a finite time. Proton emission is not seen in naturally occurring isotopes proton emitters can be produced via nuclear reaction s, usually utilising some kind of particle accelerator . Although prompt i.e. not beta delayed proton emission was observed from an isomer in Cobalt Isotopes Cobalt 53 as early as 1969, no other proton emitting states were found until 1981, when the proton radioactive ground states of Lutetium Isotopes Lutetium 151 and Thulium Isotopes Thulium 147 were observed at experiments at the Gesellschaft f r Schwerionenforschung GSI in West Germany.

Zero emission refers to an engine , electric motor motor , or other energy source, that emits no waste products that pollutes the environment or disrupts the climate. Zero emission engines Vehicles and other mobile machinery used for transport over land, sea, air, rail and for other uses agricultural, mobile power generation, etc. contribute heavily to climate change and pollution, so zero emission engines are an area of active research. These technologies almost in all cases include an Electric motor electric engine powered by an energy source compact enough to be installed in the vehicle. These sources include hydrogen fuel cell s, Traction battery batteries , supercapacitors , and flywheel energy storage devices. In some cases, such as Air engine compressed air engines , the engine may be mechanical rather than electrical. This mechanical engine is then powered by a passive energy source like compressed air , or a combustible non polluting gas like hydrogen . The above engines can be used in all vehicles, from cars to boats to propeller airplanes. For boats, energy sources such as nuclear power and Photovoltaics solar panels can also be a viable option, in addition to traditional sail s and turbosail s. A concept like vegetable oil economy produces emissions however, the only emissions are things that were first taken out of the atmosphere when the plants were growing. So there is no net emission.

Nasal emission is the abnormal passing of oral air through a palatal cleft , or from some other type of Velopharyngeal inadequacy velopharyngeal inadequacy VPI , during the production of a consonant that requires a buildup of oral air pressure for proper pronunciation , such as p or s . The escaping air tends to reduce the oral air pressure and impede the proper production of the consonant. Secondary effects sometimes noted with nasal emission are the development of improper compensatory pronunciation habits, including using a very soft voice that uses less breath pressure. Nasal emission can be detected by a number of simple techniques, such as looking for the fogging of a mirror held under the nares ref http www.asha.org about publications leader online archives 2006 060207 060207c.htm Kummer, A.

An otoacoustic emission OAE is a sound which is generated from within the inner ear . Having been predicted by Thomas Gold in 1948, its existence was first demonstrated experimentally by David Kemp hearing David Kemp in 1978 ref Kemp DT. Stimulated acoustic emissions from within the human auditory system. J Acoust Soc Am. 1978 64 1386 1391, doi 10.1121 1.382104 ref and otoacoustic emissions have since been shown to arise by a number of different cellular mechanisms within the inner ear . Fact date July 2008 Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health. Broadly speaking, there are two types of otoacoustic emissions spontaneous otoacoustic emissions SOAEs , which can occur without external stimulation, and evoked otoacoustic emissions EOAEs , which require an evoking Stimulus physiology stimulus . Mechanism of occurrence OAEs are considered to be related to the amplification function of the cochlea . In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the production of sound. Several lines of evidence suggest that, in mammals, outer hair cells are the elements that enhance cochlear sensitivity and frequency selectivity and hence act as the energy sources for amplification. One theory is that they act to increase the discriminability of signal variations in continuous noise by lowering the masking effect of its cochlear ampli cation. ref Lilaonitkul W, Guinan JJ Jr. 2009 .

Basic process A Nonlinear optics nonlinear crystal is used to split photon s into pairs of photons that, in accordance with the law of conservation of energy , have combined energies and momenta equal to the energy and momentum of the original photon, are phase matching phase matched in the frequency domain, and have correlated polarization waves polarizations . The state of the crystal is unchanged by the process. If the photons share the same polarisation it is deemed Type I correlation if they have perpendicular polarisations it is deemed Type II. The fundamental reason why some of the photons are split is not understood. ref L. Gilder, The Age of Entanglement , Vintage Books, New York, 2008, p. 299. ref SPDC is stimulated by random vacuum fluctuation s, and hence the photon pairs are created at random times.
