| Terms for subject Environment (5179 entries) |
| àcid sulfhídric | hydrogen sulphide (Flammable, poisonous gas with characteristic odour of rotten eggs, perceptible in air in a dilution of 0.002 mg/l. It is used as a reagent in chemical analysis; extremely hazardous; collapse, coma and death from respiratory failure may come within a few seconds after one or two inspirations; low concentrations produce irritation of conjunctiva and mucous membranes. Headache, dizziness, nausea, lassitude may appear after exposure, H2S) | |
| àcid sulfúric | sulphuric acid (A toxic, corrosive, strongly acid, colorless liquid that is miscible with water and dissolves most metals, and melts at 10C; used in industry in the manufacture of chemicals, fertilizers and explosives, and in petroleum refining) | |
| acidesa | acidity (The state of being acid that is of being capable of transferring a hydrogen ion in solution) | |
| acidesa forta | strong acidity (High degree of ionization of an acid in water solution) | |
| acidificació | acidification (Addition of an acid to a solution until the pH falls below 7) | |
| acidificació del sòl | soil acidification (A naturally occurring process in humid climates that has long been the subject of research, whose findings suggest acid precipitation effects. The generally accepted impact of soil acidification on the productivity of terrestrial plants is summarised as follows: as soil becomes more acidic the basic cations (Ca, Mg) on the soil exchange are replaced by hydrogen ions or solubilized metals. The basic cation, now in solution, can be leached through the soil. As time progresses the soil becomes less fertile and more acidic. Resultant decreases in soil pH cause reduced, less-active population of soil microorganisms, which in turn slow decomposition of plant residues and cycling of essential plant nutrients) | |
| acord | agreement (The coming together in accord of two minds on a given proposition. In law, a concord of understanding and intention between two or more parties with respect to the effect upon their relative rights and duties, of certain past or future facts or performances. The consent of two or more persons concerning respecting the transmission of some property, right, or benefits, with the view of contracting an obligation, a mutual obligation; legal) | |
| acord comú | common agreement (A system of law established by following earlier judicial decisions and customs, rather than statutory or legislatively enacted law) | |
| acord internacional | international agreement (Cooperation in international efforts to support global environmental goals. Solutions to environmental problems such as trans-boundary airborne and waterborne pollution, ozone depletion and climate change require action by all responsible countries) | |
| acord multilateral | multilateral agreement (Multilateralism stands for a long-held but rarely achieved ideal, namely the voluntary co-operation of nations for peace and development. Multilateral initiatives are undermined or diluted by ultra-nationalist, bilateral and regional initiatives. Multilateralism may be undercut by the uncoordinated decisions of those contributing to it. Multilateralism constitutes the democracy of international society. An enlightened multilateralism enhances the specific interests of states while advancing their common cause) | |
| acord sobre depòsit en embalatge | arrangement for a deposit on packaging (Agreement to provide refunds or payments in exchange for used bottles or packaging materials) | |
| acta | chart (A formal written record of transactions, proceedings, etc., as of a society, committee, or legislative body; act) | |
| acte administratiu | administrative deed (Any formal and legitimate step taken or decision made on matters of policy by a chief or other top-level officer within an organization) | |
| acte comunitari | Community act | |
| acte de comerç | commercial transaction (The conduct or carrying on of trade, business or a financial matter to a conclusion or settlement) | |
| acte governamental il·legal | wrongful government act (A deed performed by a government official or agent in exercise of police, constitutional, legislative, administrative or judicial powers that infringes upon the rights of another and causes damage, without protecting an equal or superior right) | |
| acte il·legal | wrongful act (An act contrary to the rules of natural or legal justice) | |
| acte jurídic | juridical act (Acts relating to the administration of justice) | |
| actes | act (1. Something done voluntarily by a person, and of such a nature that certain legal consequences attach to it. 2. Documents, decrees, edicts, laws, judgments, etc.) | |
| actini | actinium (A radioactive element of the actinide series, occurring as a decay product of uranium. It is used as an alpha particle source and in neutron production) |
