| Terms for subject Environment (6533 entries) |
| atmospheric ozone (A triatomic molecule of oxygen; a natural constituent of the atmosphere, with the highest concentrations in the ozone layer or stratosphere; it is found at a level between 15 and 30 km above the Earth, which prevents harmful ultraviolet B radiation, which causes skin cancer and threatens plant life, from reaching the ground. The fragile shield is being damaged by chemicals released on Earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons (CFCs), which are used in refrigerators, aerosols and as cleaners in many industries and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine) | ozon atmosferic | |
| atmospheric particulate (A concentration of fine liquid or solid particles, such as dust, smoke, mist, fumes or smog, found in the atmosphere) | particulă atmosferică | |
| atmospheric physics (The study of the physical phenomena of the atmosphere) | fizică atmosferică | |
| atmospheric pollution (The presence in the air of one or more contaminants in such a concentration and of such duration as to cause a nuisance or to be injurious to human life, animal life or vegetation) | poluare atmosferică | |
| atmospheric pollution | poluarea aerului | |
| atmospheric precipitation (The settling out of water from cloud in the form of dew, rain, hail, snow, etc.) | precipitaţii atmosferice | |
| atmospheric process (Atmospheric processes are distinguished in physical and chemical processes and both types may be operating simultaneously in complicated and interdependent ways. The physical processes of transport by atmospheric winds and the formation of clouds and precipitation strongly influence the patterns and rates of acidic deposition, while chemical reactions govern the forms of the compounds deposited) | proces atmosferic | |
| atmospheric science (The atmospheric sciences study the dynamics, physics and chemistry of atmospheric phenomena and processes, including the interactions of the atmosphere with soil physics, hydrology and oceanic circulation. The research focuses on the following areas: turbulence and convection, atmospheric radiation and remote sensing, aerosol and cloud physics and chemistry, planetary atmospheres, air-sea interactions, climate, and statistical meteorology) | ştiinţa atmosferei | |
| atmospheric structure (The gaseous area surrounding the planet is divided into several concentric spherical strata (layers, like shells) separated by narrow transition zones. The boundaries are know as "pause". More than 99% of the total atmospheric mass is concentrated in the first 40 km from the Earth's surface. Atmospheric layers are characterized by differences in chemical composition that produce variations in temperature) | structură atmosferică | |
| atrazine (Herbicide belonging to the triazine group, widely employed and particularly in maize crops. It is highly toxic for phytoplancton and freshwater algae and, being highly soluble in water, it easily contaminates aquifers) | atrazină | |
| attribute (A distinctive feature of an object. In mapping and GIS applications, the objects are points, lines, or polygons that represent features such as sampling locations, section corners (points); roads and streams (lines); lakes, forest and soil types (polygons). These attributes can be further divided into classes such as tree species (Douglas-fir and ponderosa pine) for forest types and paved and gravel for road types. Multiple attributes are generally associated with objects that are located on a single map layer) | atribut | |
| attribution (Under certain circumstances, the tax law applies attribution rules to assign to one taxpayer the ownership interest of another taxpayer) | atribuire | |
| auction monitor | autoritate de monitorizare a licitațiilor | |
| audio-visual presentation (An exhibition, performance, demonstration or lecture utilizing communication media directed at both the sense of sight and the sense of hearing) | prezentare audiovizuală | |
| audiovisual equipment (Equipment designed to aid in learning and teaching by making use of both hearing and sight) | echipament audio-vizual | |
| audiovisual media (Any means of communication transmitted to both the sense of hearing and the sense of sight, especially technologies directed to large audiences) | media audio-vizuală | |
| audit (The periodic or continuous verification of the accounts, assets and liabilities of a company or other organization, often to confirm compliance with legal and professional standards) | audit | |
| audit frequency | periodicitate în auditare | |
| authorisation (An official certification of competence or a transfer of the right and power to act, including permission from government to use state funds for a particular program or project) | autorizare | |
| authority body (An organized assemblage of authorized persons or officials empowered to implement and enforce laws, oversee jurisdictions, settle disputes, adjudicate or make some other legal determination) | organ executiv |
