What does «desecación» mean in Spanish?
- Action and effect of drying or drying out. Elimination of the moisture contained in something.
Examples of use in Spanish: "La Laguna de los Cisnes presenta una gran desecación durante las temporadas de verano".
"esta crema es muy buena hidratante y previene la desecación que se produce al exponerse al sol".
"La piel del cadáver se observa dura, como cuero curtido y su volumen es mucho menor debido al proceso de desecación".
- In veterinary medicine, an accident that occurs in the hoof surrounding the horse's foot.
- In Botany, operation that removes moisture from plants to preserve them in herbariums.
- In agriculture, artificial drainage of a field or land that is too wet to be used for any purpose.
Examples of use in Spanish: "métodos y modos de desecación de terrenos húmedos por excesivas precipitaciones y acumulación de agua".
- In chemistry, the removal of water contained in certain substances by raising their vapor tension to a point above that in the environment, which may be achieved either by heating the substance to increase the vapor tension of the retained water or by decreasing the total pressure that gravitates on the substance. Since the total pressure is equal to the sum of the partial pressures of the components, a hygroscopic material, such as sulfuric acid or calcium chloride, which absorbs moisture from the environment, will reduce the total pressure gravitating on the substance. The water present in the substance, having a higher vapor pressure than that of the medium, will tend to escape and will be absorbed by the hygroscopic material. The process will continue until this material is so diluted that it has lost its absorption capacity. Desiccation can also be carried out by lowering the pressure with the aid of a vacuum pump or by blowing dry air over the wet substance.
- In industry, a state of extreme dryness or the process of extreme drying. A desiccant is a hygroscopic (attracts and retains water) substance that induces or sustains such a state in its vicinity in a moderately sealed container. Desiccation is widely employed in the oil and gas industry. These materials are obtained in a hydrated state, but the water content leads to corrosion or is incompatible with further processing. Water removal is achieved by cryogenic condensation, absorption in glycols and absorption in desiccants such as silica gel.
- In biology and ecology, it refers to the desiccation of a living organism, such as when aquatic animals are removed from water, slugs are exposed to salt, or when plants are exposed to sunlight or drought. Ecologists frequently study and assess the susceptibility of various organisms to desiccation. For example, in one study researchers found that Caenorhabditis elegans dauer is a true anhydrobiotic that can resist extreme desiccation and that the basis for this ability lies in trehalose metabolism.
- (desecación del suelo) The process of forming polygonal cracks in compacted soil as water and moisture are lost during periods of drought.
