|
| neutralizazio |
neutralisation (To make a solution neutral by adding a base to an acidic solution, or an acid to a basic solution) |
|
| nikel |
nickel (A malleable ductile silvery-white metallic element that is strong and corrosion-resistant, occurring principally in pentlandite and niccolite: used in alloys, especially in toughening steel, in electroplating, and as a catalyst in organic synthesis) |
|
| nitrato |
nitrate (Any salt or ester of nitric acid, such as sodium nitrate) |
|
| nitrifikazio |
nitrification (The process by which ammonia compounds, including man-made fertilizer and the humus provided by organic matter or plant and animal origin, are converted into nitrites and then nitrates, which are then absorbed as a nutrient by crops. Excess nitrate can be leached into surface waters and groundwaters, causing pollution. Excess nitrate may also be converted by microbes back into gaseous nitrogen, which is an important greenhouse gas, and released back into the atmosphere. The ultimate source of nitrogen in the ecosystem is the molecular nitrogen in the atmosphere. To a very limited extent, some dissolves in water. However, none is found in rock) |
|
| nitrito |
nitrite (A salt or ester of nitric acid, included in compounds such as potassium nitrite, sodium nitrite and butyl nitrite) |
|
| nitrogeno |
nitrogen (An essential nutrient in the food supply of plants and the diets of animals. Animals obtain it in nitrogen-containing compounds, particularly amino acids. Although the atmosphere is nearly 80% gaseous nitrogen, very few organisms have the ability to use it in this form. The higher plants normally obtain it from the soil after micro-organisms have converted the nitrogen into ammonia or nitrates, which they can then absorb) |
|
| nitrogeno organiko |
organic nitrogen (Essential nutrient of the food supply of plants and the diets of animals. Animals obtain it in nitrogen-containing compounds, particularly aminoacids. Although the atmosphere is nearly 80% gaseous nitrogen, very few organisms have the ability to use it in this form. The higher plants normally obtain it from the soil after microorganisms have converted the nitrogen into ammonia or nitrates, which they can then absorb. This conversion of nitrogen, known as nitrogen fixation, is essential for the formation of amino acids which, in turn, are the building blocks of proteins) |
|
| nitrogenoII oxido |
nitrogen oxide (A colorless gas that, at room temperature, reacts with oxygen to form nitrogen dioxide; may be used to form other compounds, NOx) |
|
| nitrogenoIV oxido |
nitrogen dioxide (A reddish-brown gas; it exists in varying degrees of concentration in equilibrium with other nitrogen oxides; used to produce nitric acid, NO2) |
|
| nitrogenoI oxido |
nitrogen monoxide (A colourless gas, soluble in water, ethanol and ether. It is formed in many reactions involving the reduction of nitric acid, but more convenient reactions for the preparation of reasonably pure NO are reactions of sodium nitrite, sulphuric acid, etc.) |
|
| nitrogeno-finkatze biologiko |
biological nitrogen fixation |
|
| nitrogeno-konposatu |
nitro compound (Any one of a class of usually organic compounds that contain the monovalent group, -NO2 (nitro group or radical) linked to a carbon atom) |
|
| nitrogeno-oxidoak |
nitrogen oxides (Oxides formed and released in all common types of combustion; they are formed by the oxidation of atmospheric nitrogen at high temperatures. Introduced into the atmosphere from car exhausts, furnace stacks, incinerators, power stations and similar sources, the oxides include nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen pentoxide and nitric acid. The oxides of nitrogen undergo many reactions in the atmosphere to form photochemical smog) |
|
| nitrogenoaren finkapen |
nitrogen fixation (Assimilation of atmospheric nitrogen by a variety of microorganisms which live freely in soil. Once the nitrogen has been captured by one of the microorganisms, there are many different routes by which it is handled. Some is retained in the soil as decomposing plant matter, waiting to be released and taken up by new crops as a nitrate. That nitrate is produced by nitrifying bacteria living in the soil that thrive on ammonia, which is produced by decaying plant and animal material. In processing nitrogen the nitrifying bacteria produce nitrate that can be absorbed by the roots of plants) |
|
| nitrogenoaren ziklo |
nitrogen cycle (The complex set of processes by which crops acquire the large amount of nitrogen they need to make proteins, nucleic acids and other biochemicals of which they are composed, and how the nitrogen returns to the atmosphere) |
|
| nitrosamina |
nitrosamine (Any one of a class of neutral, usually yellow oily compounds containing the divalent group = NNO) |
|
| nomada |
nomad (1. A member of a people or tribe who move from place to place to find pasture and food. 2. Nomads include gypsies, desert tribes such as the Bedouin and the many primitive tribes in the Americas, Asia and Australia. Herding survives as a way of life around the Sahara, in the Middle East, in Asia as far east as western India, and in the Asian parts of the USSR. The end of pastoral nomadism would be regrettable not merely on account of the independence and distinctiveness of this way of life but because this type of economy may be a more rational means of raising large numbers of animals under arid conditions than is capital-intensive ranching) |
|
| nomenklatura |
nomenclature (A system of names or terms, particularly those related to a specific area of science or art, or the assignment of names to things) |
