Acoustic Emission AE is a naturally occurring phenomenon whereby external stimuli, such as mechanical loading, generate sources of elastic wave s. AE occurs when a small surface displacement of a material is produced. This occurs due to stress wave s generated when there is a rapid release of energy in a material, or on its surface. The wave generated by the AE source, or, of practical interest, in methods used to stimulate and capture AE in a controlled fashion for study and or use in inspection, quality control, system feedback, process monitoring and others. Acoustic Emission phenomena AEs are commonly defined as transient elastic waves within a material caused by the release of localized stress energy. Hence, an event source is the phenomenon which releases elastic energy into the material, which then propagates as an elastic wave. Acoustic emissions can be detected in frequency ranges under 1 kHz, and have been reported at frequencies up to 100 MHz. Rapid stress releasing events generate a spectrum of stress waves starting at 0 Hz and typically falling off at several MHz. AE is related to an irreversible release of energy, and can be generated from sources not involving material failure including friction , cavitation and impact force impact . Additionally, events can also come quite rapidly when materials begin to fail, in which case AE activity rates are studied as opposed to individual events. AE events that are commonly studied among material failure processes include the extension of a fatigue material fatigue crack , or fiber breakage in a composite material .

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. Fact date December 2007 Research in the field flourished after this breakthrough, and to date more than 25 isotopes have been found to exhibit proton emission. The study of proton emission has aided the understanding of nuclear deformation, masses and structure, and it is a wonderfully pure example of quantum tunneling .

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.
