تعريف nitrous oxide في الإنجليزية الإنجليزية القاموس.
A non-flammable gas (N2O) commonly used in surgery and dentistry for its anaesthetic and analgesic effects
– a type of gas that can be used to induce anxiolysis or conscious sedation
one of the three major greenhouse gases responsible for climate change (see greenhouse gases) Soils and oceans are the primary natural sources of nitrous oxide Humans contribute to nitrous oxide emissions through soil cultivation and the use of nitrogen fertilizers, nylon production and the burning of organic material and fossil fuels Combustion and biomass burning are sources of nitrous oxide emissions Agricultural practices may stimulate emissions of nitrous oxide from soils and play a major role in the build-up of nitrous oxide in the atmosphere
Gas found in the atmosphere that contributes to the greenhouse effect Sources for nitrous oxide include: land-use conversion; fossil fuel combustion; biomass burning; and soil fertilization Chemical formula for nitrous oxide is N2O
A gas consisting of two nitrogen atoms and one oxygen atom It is an important greenhouse gas
Colorless gas, formula N2O, released by bacterial activity at the earth's surface It has an atmospheric lifetime of about 160 years and is currently present at a level of about 330 ppb Its atmospheric significance is that it is transported into the stratosphere, where its reaction with excited oxygen atoms (O1D) is the major source of active nitrogen; it is also a major greenhouse gas In large amounts, it has anesthetic properties (laughing gas)
An important greenhouse gas, with a global warming potential of 320 times as much as carbon dioxide according to the IPCC The primary source of N2O emissions under current conditions are estimated to come from agricultural soils that have high nitrogen levels due to the application of fertilizers at times or in amounts that exceed the ability of vegetation to quickly absorb the nitrogen into plant metabolism The conversion of cropland to forest, accompanied by a significant reduction in the use of commercial fertilizers, may be an important contributor to reducing emissions of N2O from that land, but scientific methods of estimating that impact are not well developed at this time Therefore, NCOC will not attempt to calculate the impact of afforestation projects on N2O emissions at this time
A greenhouse gas given off mainly by current agricultural methods; its direct global warming potential over 100 years is 270 times greater than that of carbon dioxide per volume
a composed of two nitrogen molecules and one oxygen molecule It is a bi-product of the natural process of vegetation decay, particularly rice paddies It is released by nitrogen-based fertilizers which are heavily used today Nitrous oxide is also produced by the burning of coal and the exhaust from cars Nitrous oxide has the same effects of CFCs, but N2O molecules absorb 250 times as much heat as carbon dioxide
Nitrous oxide is a compound that is made up of two parts oxygen to one part nitrogen A gas at room temperature and a liquid under pressure When heated, it breaks down into its two elements
Nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight) When the nitrous oxide is heated it breaks down and releases extra oxygen, However, it is not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel By burning more fuel, higher cylinder pressures are created and this is where most of the additional power is realized Illegal to use in any NASCAR stock car series Both A J Foyt's and Darrell Waltrip's qualifying times in the 1976 Daytona 500 were thrown out because of evidence of Nitrous Oxide use
A powerful greenhouse gas with a global warming potential of 320 Major sources of nitrous oxide include soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning
A powerful greenhouse gas Its major sources include soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning
A controlled mixture of nitrogen and oxygen gases (N2O) that is inhaled by the person in order to decrease sensitivity to pain and/or anxiety Also referred to as laughing gas Click here for more about nitrous oxide
A potent greenhouse gas, the primary anthropogenic emissions of which are thought to come from agricultural fertilizers, and to a lesser degree, fossil fuel combustion and biomass burning It is considered to be 320 times as powerful a greenhouse gas as CO2 over a 100-year time frame Should be differentiated from oxides of nitrogen (NOx)
A gaseous emission that comes from sources such as automobile emissions and other fossil fuel burning sources Recently enacted federal emissions standards for nitrous oxide will have a major impact on Ohio's coal-fired generating plants
A colorless, sweet-tasting gas, NO, used as a mild anesthetic in dentistry and surgery. a type of gas used by dentists to reduce pain = laughing gas. or laughing gas Inorganic compound, one of the oxides of nitrogen. A colourless gas with a pleasantly sweetish odour and taste, it has an analgesic effect when inhaled; it is used as an anesthetic (often called just "gas") in dentistry and surgery. This effect is preceded by mild hysteria, sometimes with laughter, hence the name laughing gas. It is also used as a propellant in food aerosols and as a leak detector
An inhalant, also known as "laughing gas " Nitrous oxide is a weak anesthetic that does not produce unconsciousness
is released by industrial processes, the burning of fossil fuels, and by fertilizer use Nitrous oxide evenutually breaks down into its components, nitrogen and oxygen, but the process takes about 120 years
A powerful greenhouse gas emitted through soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning This GHG is listed in Annex A of the Kyoto Protocol
A controlled mixture of nitrogen and oxygen gases (N2O) that is inhaled by the patient in order to decrease sensitivity to pain Also referred to as laughing gas
Produced biologically in oceans and soil Activities by humans such as vehicle exhausts, biomass burning, industrial combustion, and chemical fertilizers produce nitrous oxides Nitrous oxide is also used as a mild anesthetic in dentistry and surgery commonly know as "laughing gas"
