Emission spectroscopy developed in the late 19th century and efforts in theoretical explanation of atomic emission spectra eventually led to quantum mechanics.

Interaction with electromagnetic radiation is used in fluorescence spectroscopy, protons or other heavier particles in Particle-Induced X-ray Emission and electrons or X-ray photons in Energy-dispersive X-ray spectroscopy or X-ray fluorescence.

Emission spectroscopy is often referred to as optical emission spectroscopy, due to the light nature of what is being emitted.

* Emission ( electromagnetic radiation ), the process by which the energy of a photon is released by another entity

* Emission theory ( vision ), the proposal that visual perception is accomplished by rays of light emitted by the eyes

To separate and analyze them, the fluorescent radiation is passed through an Emission monochromator, and observed selectively by a detector.

ICAO is currently opposed to the inclusion of aviation in the European Union Emission Trading Scheme ( EU ETS ).

Historically, the word " maser " is derived from the original upper-case acronym MASER, which stands for " Microwave Amplification by Stimulated Emission of Radiation ".

Emission nebulae emit spectral line radiation from ionized gas ( mostly ionized hydrogen ); they are often called HII regions ( the term " HII " is used in professional astronomy to refer to ionized hydrogen ).

Detailed Thermal Emission Imaging System | THEMIS daytime infrared image mosaic of Olympus Mons. Olympus Mons lies at the edge of the Tharsis bulge, a vast volcanic plateau that is very ancient.

The European Pollutant Emission Register is a type of PRTR providing access to information on the annual emissions of industrial facilities in the Member States of the European Union, as well as Norway.

In the 1990s, researchers began to use Electroencephalography ( EEG ), Positron Emission Tomography ( PET ) and more recently functional Magnetic Resonance Imaging ( fMRI ), which is now the most widely used imaging technique to help localize personality traits in the brain.

* Emission indicates that radiative energy is released by the material.

For greenhouse gases the largest is the European Union Emission Trading Scheme, whose purpose is to avoid dangerous climate change.

* Emission is the unwanted generation of electromagnetic energy by some emitter or source.

The principal source of noise in DFAs is Amplified Spontaneous Emission ( ASE ), which has a spectrum approximately the same as the gain spectrum of the amplifier.

The initial spontaneous emission is therefore amplified in the same manner as the signals, hence the term Amplified Spontaneous Emission.

A much higher quality DEM from the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) instrument of the Terra satellite is also freely available for 99 % of the globe, and represents elevation at a 30 meter resolution.

Field Emission Electric Propulsion ( FEEP ) is an electrostatic propulsion concept based on field ionization of a liquid metal and subsequent acceleration of the ions by a strong electric field.

Emission of isoprene is also observed in some bacteria and this is thought to come from non-enzymatic degradations from DMADP.

Emission is the opposite of absorption, it is when an object emits radiation.

Emission from the Sun at centimetric ( radio ) wavelength is due primarily to coronal plasma trapped in the magnetic fields overlying active regions.

One trademark product of urea solution, also referred to as Diesel Emission Fluid ( DEF ), is AdBlue.

Emission of radiation is typically described using semi-classical quantum mechanics: the particle's energy levels and spacings are determined from quantum mechanics, and light is treated as an oscillating electric field that can drive a transition if it is in resonance with the system's natural frequency.

Emission lines from hot gases were first discovered by Ångström, and the technique was further developed by David Alter, Gustav Kirchhoff and Robert Bunsen.

The core of the TRIUMF nuclear medicine program is Positron Emission Tomography or PET imaging, a technique whereby tiny amounts of radioactive nuclei known as radioisotopes are combined with certain bio-molecules and injected into the body.

* Emission security ( EMSEC ): Protection resulting from all measures taken to deny unauthorized persons information of value which might be derived from intercept and analysis of compromising emanations from crypto-equipment, automated information systems ( computers ), and telecommunications systems.

A new investigation in the early 1980s, by a team under Dr. Thomas Cahill at the University of California, Davis, using Particle-Induced X-ray Emission ( PIXE ) found that only trace amounts (< 0. 0062 % by weight ) of titanium appeared to be present in the ink, which should have been too little for some of McCrone's analyses to detect.

Emission nebulae often have dark areas in them which result from clouds of dust which block the light.

After Spirit stopped working scientists studied old data from the Miniature Thermal Emission Spectrometer, or Mini-TES and confirmed the presence of large amounts of carbonate-rich rocks, which means that regions of the planet may have once harbored water.

From ITU, 1. 145 Spurious emission: Emission on a frequency or frequencies which are outside the

* Emissions trading scheme, a scheme which helps developed countries to meet their emissions reduction targets set by the Kyoto Protocol ( see also European Union Emission Trading Scheme, EU ETS )

In addition companies can purchase Certified Emission Reductions ( CERs ) which result from mitigated carbon emissions from UNFCCC approved projects for voluntary purposes.

Emission is a process by which a substance releases energy in the form of electromagnetic radiation.

Emission can occur at any frequency at which absorption can occur, and this allows the absorption lines to be determined from an emission spectrum.

Emission is maximal in the plane perpendicular to the dipole and zero in the direction of wires which is the direction of the current.

ASTER ( Advanced Spaceborne Thermal Emission and Reflection Radiometer ) is a Japanese sensor which is one of five remote sensory devices on board the Terra satellite launched into Earth orbit by NASA in 1999.

( Not to be confused with Hydrogen Fuel Cell Electric Vehicles which are certified as ZEV or Zero Emission Vehicles ) In addition to the 15 year or 150, 000 mile warranty for zero evaporative ( fuel system ) emissions, and SULEV tailpipe emissions, PHEVs must also warranty their traction battery for 10 years or 150, 000 miles.

In addition, these BMW vehicles were certified as Partial Zero Emission Vehicles ( PZEV ): they meet the SULEV tailpipe emission standard, which is approximately 1 / 5 of the ULEV standard, and they conform to the Zero Evaporative Emissions requirements.

They later spun off their FED efforts to " Field Emission Technologies ", which continued to aim for a 2009 release.

After Spirit stopped working scientists studied old data from the Miniature Thermal Emission Spectrometer, or Mini-TES and confirmed the presence of large amounts of carbonate-rich rocks, which means that regions of the planet may have once harbored water.

An often-shown program is La Grosse Emission which helped popularize the comedians troupe named Les Robins des Bois ( The Robinhoods ).

The Boston College Law School study also cites proceedings in which an Arizona dentist, " is facing sanctions for advocating alternative materials ", a California dentist lost his license, " for running an advertisement entitled: " Mercury Emission from Silver Filings Unsafe by Government Standards ", and a Maryland dentist, " was sanctioned for writing an article on dental amalgam removal ".

The Clean Development Mechanism ( CDM ) is one of the flexibility mechanisms defined in the Kyoto Protocol ( IPCC, 2007 ) that provides for emissions reduction projects which generate Certified Emission Reduction units which may be traded in emissions trading schemes.
