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.

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.

* National Emission Ceiling, part of EU Directive 2001 / 81 / EC regarding air pollution

* PZEV ( Partial Zero Emission Vehicle ): Meets SULEV tailpipe standards, has a 15-year / 150, 000 mile warranty, and zero evaporative emissions.

Maximum wavelengths of absorption (≈ excitation ) and emission ( for example, Absorption / Emission = 485 nm / 517 nm ) are the typical terms used to refer to a given fluorophore, but the whole spectrum may be important to consider.

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.

* Distributed emission regeneration family-Designator, Electromagnetic Emission, IFF / ATC / NAVAIDS, Underwater Acoustic, Supplemental Emission / Entity State ( SEES )

The ACC has published criteria for Single-Photon Emission Computed Tomography Myocardial Perfusion Imaging ( SPECT MPI ), Cardiac Computed Tomography ( CCT ) and Cardiac Magnetic Resonance ( CMR ) Imaging, resting transthoracic and transesophageal echocardiography ( TTE / TEE ) and echocardiography.

Excitation / Emission spectra of Hoechst dyes.

KEA sells its Emission Certified Diesel and Spark ignited engines from 6 to 100 hp in the US and Central / South America.

) The European Commission has oversight of the NAP process and decides if the NAP fulfills the twelve criteria set out in the Annex III of the Emission Trading Directive ( EU Directive 2003 / 87 / EC ).

Available spacecraft data include, in particular, retrievals of temperature and dust / water ice optical ticknesses from the Thermal Emission Spectrometer onboard NASA's Mars Global Surveyor and the Mars Climate Sounder onboard NASA's Mars Reconnaissance Orbiter.

no: Thermal Emission Imaging System

Emission theories obey the principle of relativity by having no preferred frame for light transmission, but say that light is emitted at speed " c " relative to its source instead of applying the invariance postulate.

* Standardized Uptake Value, a measure used in Positron Emission Tomography for quantification

It is also used as a measure of environmental emissions ( by mass ) per MWh of electricity generated, see: Emission factor.

Tropospheric Emission Spectrometer or TES is a satellite instrument designed to measure the state of the earth's troposphere.

* Sounding of the Atmosphere using Broadband Emission Radiometry ( SABER ): Multichannel radiometer designed to measure heat emitted by the atmosphere over a broad altitude and spectral range, as well as global temperature profiles and sources of atmospheric cooling.

* ICP-AES ( Inductively Coupled Plasma-Atomic Emission Spectrometry ), a machine to measure electromagnetic radiation emitted by atoms at a wavelength characteristic of a particular element

Emission spectra indicated Af calcium and all other impurities much lower.

* Emission spectroscopy, photoemission spectroscopy, flame emission spectroscopy and other types of spectroscopy

Emission can also be induced by other sources of energy such as flames or sparks or electromagnetic radiation in the case of fluorescence.

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.

In November 2009, Abbott resigned from shadow ministerial responsibilities due to the Liberal Party's position on the government's Emission Trading Scheme ( ETS ), leading to the resignation of other shadow ministers.

Emission test results from individual vehicles are in many cases compiled to evaluate the emissions performance of various classes of vehicles, the efficacy of the testing program and of various other emission-related regulations ( such as changes to fuel formulations ) and to model the effects of auto emissions on public health and the environment.
