| bestiar equí |
horse (A large animal with four legs which people ride on or use for carrying things or pulling vehicles) |
|
| bestiar vaccí per a carn |
beef cattle (Cattle bred for the production of meat) |
|
| betum |
bitumen (A generic term applied to natural inflammable substances of variable colour, hardness, and volatility, composed principally of a mixture of hydrocarbons substantially free from oxygenated bodies. Bitumens are sometimes associated with mineral matter, the nonmineral constituents being fusible and largely soluble in carbon disulfide, yielding water-insoluble sulfonation products. Petroleum, asphalts, natural mineral waxes, and asphaltites are all considered bitumens) |
|
| bibligorafia |
bibliography (A complete or selective listing of documents by a given subject, author or publisher, often including the description and identification of the editions, dates of issue, titles, authorship, publishers or other written materials) |
|
| biblioteca |
library (Place where books and other literary materials are kept) |
|
| bicicleta |
bicycle (A vehicle with two wheels in tandem, pedals connected to the rear wheel by a chain, handlebars for steering, and a saddlelike seat) |
|
| bifenil halogenat |
halogenated biphenyl (Halogen derivatives of biphenyl) |
|
| bioacumulació |
bioaccumulation (1. The accumulation of pollutants in living organisms by direct adsorption or through food chains. 2. Accumulation by an organism of materials that are not an essential component or nutrient of that organism. Usually it refers to the accumulation of metals, but it can apply to bioaccumulation of persistent synthetic substances such as organochlorine compounds. Many organisms, such as plants, fungi and bacteria, will accumulate metals when grown in solutions containing them. The process can be employed usefully as a purification process to remove toxic heavy metals from waste water and contaminated land) |
|
| biocarburant |
biofuel (A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is beginning to be exploited to supply the ever-increasing energy demand around the world. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol) |
|
| biocenosi |
biocoenosis (A community or natural assemblage of organisms; often used as an alternative to ecosystem but strictly is the fauna/flora association excluding physical aspects of the environment) |
|
| biocida |
biocide (A diverse group of poisonous substance including preservatives, insecticides, disinfectants and pesticides used for the control of organisms that are harmful to human or animal health or that cause damage to natural or manufactured products) |
|
| bioclimatologia |
bioclimatology (The study of climate in relation to fauna and flora) |
|
| biodegradabilitat |
biodegradability (The extent to which a substance can be decomposed - or rotted - by bacteria and fungi. Implies that residues from degradation are nontoxic. One of the most misleading claims in business, because shoppers often assume a biodegradable product to be harmless. Some harmful compounds take much longer to degrade than others and the product can harm the environment while it is rotting. Biodegradation may also be incomplete, sometimes leaving residues in the environment which are more harmful than the original substance. Accumulation in the environment of nonbiodegradable (or poorly biodegradable) substances, such as some biocides, can cause serious problems) |
|
| biodegradació |
biodegradation (Breaking down of a substance by microorganisms) |
|
| biodiversitat |
biodiversity (1. Genetic diversity: the variation between individuals and between populations within a species; species diversity: the different types of plants, animals and other life forms within a region; community or ecosystem diversity: the variety of habitats found within an area - grassland, marsh, and woodland for instance. 2. An umbrella term to describe collectively the variety and variability of nature. It encompasses three basic levels of organisation in living systems: the genetic, species, and ecosystem levels. Plant and animal species are the most commonly recognized units of biological diversity, thus public concern has been mainly devoted to conserving species diversity) |
|
| biofiltratge |
biofiltration (The distribution of settled sewage on a bed of inert granular material through which it is allowed to percolate. In doing so, the effluent is aerated thus allowing aerobic bacteria and fungi to reduce its biochemical oxygen demand) |
|
| biofiltre |
trickling filter (A system of secondary sewage treatment which is similar to self-purification action of streams; it is more accurately a biological oxidizing bed; the effluent is placed on the stones in the bed and microorganisms present consume the solids as a food supply) |
|
| biofísica |
biophysics (The hybrid science involving the application of physical principles and methods to study and explain the structures of living organisms and the mechanics of life processes) |
|
| biogeografia |
biogeography (The science concerned with the geographical distribution of animal and plant life) |
|
| biogeoquímica |
biogeochemistry |
