| Terms for subject Environment (6533 entries) |
| new technology (Electronic instruments and devices which have recently been developed and are been introduced into industry. New technologies have been introduced often in almost total ignorance or disregard of the biological and ecological systems that they subsequently disturb, and of the dynamic and evolving nature of living systems) | tehnologie nouă | |
| new town (Any of several recent urban developments that constitute small and essentially self-sufficient cities with a planned ordering of residential, industrial, and commercial development) | oraş nou | |
| newsgroup (A discussion group on a specific topic maintained on a computer network, frequently on the Internet) | grup de ştiri | |
| newsletter (A printed periodical bulletin circulated to members of a group) | scrisoare de informare | |
| 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) | nichel | |
| NIMBY aptitude (aptitude "not in my back yard"; Not In My BackYard: phrase used to describe people who encourage the development of agriculture land for building houses or factories, provided it is not near where they themselves are living) | atitudinea "Nu în curtea mea" | |
| nitrate (Any salt or ester of nitric acid, such as sodium nitrate) | nitrat | |
| 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) | nitrificare | |
| nitrite (A salt or ester of nitric acid, included in compounds such as potassium nitrite, sodium nitrite and butyl nitrite) | nitrit | |
| 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) | compus azotic | |
| 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) | azot | |
| 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) | ciclu al azotului | |
| 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) | dioxid de azot | |
| 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) | fixare a azotului | |
| 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.) | monoxid de azot | |
| nitrogen oxide (A colorless gas that, at room temperature, reacts with oxygen to form nitrogen dioxide; may be used to form other compounds, NOx) | oxid de azot | |
| nitrogen oxide | oxid de azot | |
| 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) | oxizi de azot | |
| nitrogen trifluoride | trifluorură de azot | |
| nitrogenous fertiliser (Fertilizer materials, natural or synthesized, containing nitrogen available for fixation by vegetation, such as potassium nitrate or ammonium nitrate) | îngrăşământ azotos |
