The United States Air Force has published a few mandatory standards regarding Emission Security:

Emission levels of formaldehyde have been found to be not more than 10 % of the criteria of key national standards.

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

* Emission standards

* Texas Low Emission Diesel standards

Emission standards for passenger cars and light commercial vehicles are summarised in the following tables.

Structured illumination can improve resolution by around two to four times and techniques like stimulated Emission Depletion microscopy are approaching the resolution of electron microscopes.

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 ).

Other names for emissions permits are carbon credits, Kyoto units, assigned amount units, and Certified Emission Reduction units ( CER ).

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

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.

Similarly, introduction of a Carbon Emission Trading Scheme may feel good, but may be counterproductive if the cost of carbon is priced too low, or if large emitters are given " free credits ".

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.

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.

Metals are commonly measured by atomic spectroscopy and mass spectrometry: Atomic Absorption Spectrophotometry ( AAS ) and Inductively Coupled Plasma Atomic Emission ( ICP-AES ) or Inductively Coupled Plasma Mass Spectrometric ( ICP-MS ) techniques.

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.

( 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.

Thus, Earth observation or weather satellite collection platforms, ocean and atmospheric observing weather buoy platforms, monitoring of a pregnancy via ultrasound, Magnetic Resonance Imaging ( MRI ), Positron Emission Tomography ( PET ), and space probes are all examples of remote sensing.

Note that the lava flows are crosscut by faults and graben, indicating that the faults are younger than the flows ( Thermal Emission Imaging System | THEMIS VIS ).

Emission from HH objects is caused by shock waves when they collide with the interstellar medium, but their motions are complicated.

where is the breakdown potential in volts DC, and are constants that depend on the surrounding gas, represents the pressure of the surrounding gas, represents the distance in centimetres between the electrodes, and represents the Secondary Electron Emission Coefficient.

VCA are also responsible for the production of the New Car Fuel Consumption and Emission Figures booklet, published annually and available free of charge from all new car dealers, or direct from VCA.

Once approved, these units are termed Certified Emission Reductions, or CERs.

Emission intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data.

The global carbon market is dominated by the European Union, where companies that emit greenhouse gases are required to cut their emissions or buy pollution allowances or carbon credits from the market, under the European Union Emission Trading Scheme ( EU ETS ).

Under schemes such as the European Union Emission Trading Scheme, EU Emission Allowances ( EUA ’ s ), which represent the right to release carbon dioxide into the atmosphere, are issued to all the largest polluters.

A Kyoto Certified Emission Reduction unit ( CER ), produced by a carbon project that has been certified by the UNFCCC's Clean Development Mechanism Executive Board, or Emission Reduction Unit ( ERU ) certified by the Joint Implementation project's host country or by the Joint Implementation Supervisory Committee, are accepted by the EU as equivalent.

* Emission standard, requirements that set specific limits to the amount of pollutants that can be released into the environment

The vehicles constructed to meet the PZEV requirements must achieve both SULEV ( Super Ultra Low Emission Vehicle ) exhaust emissions and zero evaporative ( fuel system ) emissions.

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.

* Emission control devices and systems, carburetor make and specification, and engine assembly details changed over the years to comply with market requirements and preferences.

These efficiency improvements have been enough to satisfy the government of South Korea's " Korea Ultra-Low Emission Vehicle " ( KULEV ) requirements.
