TRIVALENT [16 records]

Record 1 2012-03-21

English

Subject field(s)
  • Chemistry
  • Water Treatment (Water Supply)
CONT

The higher the valency, the more effective the coagulation action will be. When choosing a coagulant, its harmlessness and its cost must be taken into account. Thus, trivalent iron or aluminium salts have been and continue to be widely used in all water coagulation treatments.

Key term(s)
  • trivalent aluminum salt

French

Domaine(s)
  • Chimie
  • Traitement des eaux
CONT

La coagulation est d'autant plus efficace que la valence du cation est élevée. Le choix du coagulant doit tenir compte de l'innocuité du produit choisi et de son goût. Ainsi, les sels de fer ou d'aluminium trivalents ont été, et continuent d'être, largement utilisés dans tous les traitements de coagulation d'eau.

Subject field(s)

CONT

Three-valued logic is an extension to traditional logic that involves an additional value "unknown" in addition to "true" and "false."

Key term(s)
  • 3-valued logic

French

Domaine(s)
  • Mathématiques
  • Mathématiques informatiques
OBS

Quand, dans une condition logique élémentaire d’une requête SQL, un attribut de valeur nulle est testé, la valeur logique rendue par la condition n'est ni «vrai», ni «faux», mais «inconnu» (unknown). Cela a nécessité d’étendre la logique de Boole à une logique à trois valeurs : «true», «false» et «unknown».

Subject field(s)
  • Genetics
DEF

Pattern formed by three homologous chromosomes, after their partial opening and the joining of the corresponding segments. This phenomenon occurs at the zygotene or pachytene stages and is reversible.

CONT

(Chromosome mutation) The three homologous chromosomes in the trisomic parent may pair in a variety of ways forming either a bivalent and a univalent, or a trivalent or they may fail to pair so that three univalents are formed.

Domaine(s)
  • Génétique
DEF

Figure formée par trois chromosomes homologues, après leur ouverture partielle et l'accolement des segments correspondants. Ce phénomène apparaît aux stades zygotène et pachytène, et est réversible.
