| Terms for subject Environment (6533 entries) |
| manipulare reproductivă | reproductive manipulation (The technology involved in altering in some prescribed way the genetic constitution of an organism. Typically "useful" genes, i.e. very short sequence of DNA, are isolated from one organism and inserted into the DNA of a bacterium of yeast. These microorganisms multiply rapidly and can be cultured easily, enabling large quantities of the gene product to be obtained. Reproductive manipulation has been used for the large-scale production of antibiotics, enzymes, and hormones (e.g. insulin). Organisms into which foreign DNA has been artificially inserted are called "transgenic organisms") | |
| mapă informativă | information kit (A set or collection of materials compiled to convey knowledge on some subject and usually placed in some type of container) | |
| maquis | maquis (A low evergreen shrub formation, usually found on siliceous soils in the Mediterranean lands where winter rainfall and summer drought are the characteristic climate features. It consists of a profusion of aromatic species, such as lavender, myrtle, oleander and rosemary and often includes abundant spiny shrubs. It has been suggested that the maquis is a secondary vegetation, occupying the lands cleared of their natural evergreen oak forests by human activity) | |
| mare | sea (1. In general, the marine section of the globe as opposed to that of the land. 2. The name given to a body of salt water smaller than an ocean and generally in proximity to a continent) | |
| mare adâncă | deep sea (Region of open ocean beyond the continental shelf) | |
| Marea Caspică | Caspian Sea (No definition needed) | |
| Marea Mediterană | Mediterranean Sea (The largest inland sea between Europe, Africa and Asia, linked to the Atlantic Ocean at its western end by the Strait of Gibraltar, including the Tyrrhenian, Adriatic, Aegean and Ionian seas, and major islands such as Sicily, Sardina, Corsica, Crete, Malta and Cyprus) | |
| Marea Neagră | Black Sea (No definition needed) | |
| Marea Wadden | Wadden Sea (The Wadden sea is a shallow sea extending along the North Sea coasts of The Netherlands, Germany and Denmark. It is a highly dynamic ecosystem with tidal channels, sands, mud flats, salt marshes, beaches, dunes, river mouths and a transition zone to the North Sea, the offshore zone. Most parts of the Wadden Sea, in particular in The Netherlands and Lower Saxony, are sheltered by barrier islands and contain smaller or wider areas of intertidal flats. The present form of the Wadden Sea is the result of both natural forces and action by man. Twice a day, on average, 15 km3 of sea water enter the Wadden sea. With the water from the North Sea, large amount of sand and silt are imported which settle in places with little water movement. During low tides large parts of the Wadden Sea emerge. These so-called tidal flats cover about 2/3 of the tidal area and are one of its most characteristic features. Nowhere in the world can such a large unbroken stretch of tidal flats be found. They accountfor 60% of all tidal areas in Europe and North Africa) | |
| maree | tide (The periodic rise and fall of the water resulting from gravitational interaction between the sun, moon and earth. In each lunar day of 24 hours and 49 minutes there are two high tides and two low tides) | |
| maree roşie | red tide (Sea water which is covered or discoloured by the sudden growth of algal bloom or by a great increase in single-celled organisms, dinoflagellates. Red tides are often fatal to many forms of marine life and, in some cases, can result in human deaths because the dinoflagellates are eaten by clams and mussels which concentrate the paralysing toxins which they produce) | |
| maree verde | green tide (A proliferation of a marine green plankton toxic and often fatal to fish, perhaps stimulated by the addition of nutrients) | |
| maricultură | mariculture (Cultivation of marine organisms in their natural habitats, usually for commercial purposes) | |
| marină comercială | merchant shipping (Transportation of persons and goods by means of ships travelling along fixed navigation routes) | |
| marketing | marketing (A related group of business activities whose purpose is to satisfy the demands for goods and services of consumers, businesses and government. The marketing process includes estimating the demand, producing the product, pricing the product to satisfy profit criteria, and promoting and distributing the product) | |
| marmură | marble (Metamorphic rock composed of recrystallized calcite or dolomite) | |
| marsupial | marsupial (Type of Australian mammal with a pouch in which the young are carried. Marsupials give birth to young at a much earlier stage of development than other mammals so that the young need to be protected in the mother's pouch for some months until they become able to look after themselves) | |
| maşini | machinery (A group of parts or machines arranged to perform a useful function) | |
| maşini agricole | agricultural machinery (Machines utilized for tillage, planting, cultivation and harvesting of crops. Despite its benefits in increasing yields, mechanisation has clearly had some adverse environmental effects: deep ploughing exposes more soil to wind and water erosion; crop residues can be removed as opposed to ploughing back into the soil; removal of residues can lead to a serious loss of organic content in the soil, which may increase the risk of soil erosion) | |
| mass media | mass media (The means of communication that reach large numbers of people, such as television, newspapers, magazines and radio) |
