| Terms for subject Environment (6297 entries) |
| أنيون | anion (An ion that is negatively charged) | |
| أهداف إدارة الوقاية من الحرائق | fire management objective | |
| أهلية تشريعية | legislative competence (The skill, knowledge, qualification, capacity or authority to make, give or enact rules with binding force upon a population or jurisdiction) | |
| أوراق النبات | foliage (The green leaves of a plant) | |
| أوروبا | Europe (The second smallest continent, forming the W extension of Eurasia: the border with Asia runs from the Urals to the Caspian and the Black Sea. The coastline is generally extremely indented and there are several peninsulas (notably Scandinavia, Italy and Iberia) and offshore islands (including the British Isles and Iceland). It contains a series of great mountain systems in the south (Pyrenees, Alps, Apennines, Carpathians, Caucasus), a large central plain, and a N region of lakes and mountains in Scandinavia) | |
| أوروبا الشرقية | Eastern Europe (A geographic region of the European continent west of Asia and east of Germany and the Adriatic Sea, traditionally consisting of countries that were formerly part of the Soviet Union, such as Poland, the Czech Republic, Slovakia, Hungary, Romania, Serbia, Croatia and Bulgaria) | |
| أوروبا الغربية | Western Europe (A geographic region of the European continent surrounded by the North Sea, Atlantic Ocean and the Mediterranean Sea, including Belgium, France, Germany, Great Britain, Greece, Italy, Luxembourg, Netherlands, Portugal, Spain and other member countries of the Western European Union) | |
| أوزون الطبقات السفلى من الغلاف الجوي | tropospheric ozone (Tropospheric ozone is a secondary pollutant formed from emissions of nitrogen oxides, non-methane volatile organic compounds and carbon monoxide. Ozone scars lung tissue, makes eyes sting and throats itch. It has been implicated as a contributor to forest dieback, damage to agricultural crops, etc.) | |
| أوزون الغلاف الجوي | 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) | |
| أوقيانيا | Oceania (The islands of the southern, western and central Pacific Ocean, including Melanesia, Micronesia, and Polynesia. The term is sometimes extended to encompass Australia, New Zealand, and the Malay Archipelago) | |
| أول أكسيد الكبريت | sulphur monoxide (A gas at ordinary temperatures; produces an orange-red deposit when cooled to temperatures of liquid air; prepared by passing an electric discharge through a mixture of sulfur vapor and sulfur dioxide at low temperature) | |
| أول أكسيد الكربون | carbon monoxide (Colorless, odourless, tasteless, non-corrosive, highly poisonous gas of about the same density as that of air. Very flammable, burning in air with bright blue flame. Although each molecule of CO has one carbon atom and one oxygen atom, it has a shape similar to that of an oxygen molecule (two atoms of oxygen), which is important with regard to it's lethality, CO) | |
| أول أكسيد النيتروجين | 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.) | |
| أولوية بيئية | environmental priority | |
| أوليات - أحاديات الخلايا | protozoan (A diverse phylum of eukaryotic microorganisms; the structure varies from a simple uninucleate protoplast to colonial forms, the body is either naked or covered by a test, locomotion is by means of pseudopodia or cilia or flagella, there is a tendency toward universal symmetry in floating species and radial symmetry in sessile types, and nutrition may be phagotrophic or autotrophic or saprozoic) | |
| أيام العمل الأسبوعية | duty week | |
| أيديولوجيا | ideology (A body of ideas that reflects the beliefs and interest of a nation, political system, etc. and underlies political action) | |
| أيديولوجيا سياسية | political ideology (A belief system that explains and justifies a preferred economic and governmental order for society, offers strategies for its maintenance or attainment and helps give meaning to public events, personalities and policies) | |
| أيروسول | aerosol (A gaseous suspension of ultramicroscopic particles of a liquid or a solid) | |
| أيروسول الغلاف الجوي | atmospheric aerosol (Particulate matter suspended in the air. The particulate matter may be in the form of dusts, fumes, or mist. Aerosols in the atmosphere are the form in which pollutants such as smoke are dispersed) |
