English

Subject field(s)
  • Compartment - ISO/IEC JTC 1 Information Technology Vocabulary
Universal entry(ies)
16.03.03 (2382)
ISO/IEC standard entry number
DEF

mean value of the information content of the events in a finite set of mutually exclusive and jointly exhaustive events, that is in mathematical notation H(X)=[...] p(xi) l(xi)=[...] p(xi) log 1/p(xi) where X={x1... xn</sub>} is the set of events xi(i=1... n), l(xi) are the information contents of the events xi, and p(xi), the probabilities of the occurrences of these events, subject to [...] p(xi)=1

OBS

Example: Let X = {a,b,c} be a set of three events and let p(a) = 0,5, p(b) = 0,25 and p(c) = 0,25 be the probabilities of their occurrences. The entropy of this set is H(X) = p(a) l(a) + p(b) l(b) + p(c) l(c) = 1,5 Sh

OBS

entropy; average information content; negentropy: terms and definition standardized by ISO/IEC [ISO/IEC 2382-16:1996].

DEF

espérance mathématique de la quantité d'information des événements d'un ensemble exhaustif d'événements s'excluant mutuellement, soit mathématiquement H(X) = [...] p(xi)l(xi) = [...] p(xi)log 1/p(xi) où X = {x1 ... xn} est l'ensemble des événements xi (i = 1 ... n), l(xi) sont les quantités d'information de ces événements et p(xi) leurs probabilités de réalisation, avec [...] p(xi) = 1

OBS

Exemple : Soit X = {a,b,c) un jeu de trois événements et p(a) = 0,5, p(b) = 0,25 et p(c) = 0,25 leurs probabilités de réalisation. L'entropie de ce jeu est H(X) = p(a) l(a) + p(b) l(b) + p(c) l(c) = 1,5 Sh

Record 5 2004-02-16

English

Subject field(s)
  • Environmental Studies and Analyses
  • Toxicology
OBS

EC; effect concentration: This [toxicological value] is generally followed by a number, which indicates the percentage of a population which experience the effect.

OBS

Typical levels are EC 10, EC 25, EC 50, EC 75, EC 100. NOEC: No observable effect concentration; LOEC: Lowest observable effect concentration.

CONT

Developing Hormosira banksii embryos, used as bioassays in toxicity studies, identified ammonium as a toxicant in secondary treated sewage effluent discharged at Boags Rocks, Victoria, Australia. Ammonium did not affect fertilization but had a significant effect on germination at 48 h and cell division at 72 h with most damage occurring in the first 48 h. Ammonium showed a similar effect as whole effluent(when expressed as mg N l-1 ammonium), sampled in June, September and November 1997, on developing H. banksii embryos. This similarity is further confirmed with comparable EC50(concentration causing an effect on 50% of the population tested) and LOEC(lowest observable effect concentration) values. Mean EC50 values for the ammonium bioassays were 3. 19 mg N l-1 for germination and 6. 14 mg N l-1 for cell division.

PHR

Effect concentration low (ECL), median effect concentration (EC50), lowest observable effect concentration (LOEC), no-observed-effect concentration (NOEC), threshold effect concentration (TEC).

French

Domaine(s)
  • Études et analyses environnementales
  • Toxicologie
CONT

Concentration entraînant un effet à long terme.

CONT

Concentration minimale produisant un effet.

CONT

Évaluation du rapport dose (concentration)-réponse (effet). L'objectif est de déterminer la concentration en dessous de laquelle la substance ne devrait pas avoir d'effets indésirables sur la composante de l'environnement considérée. Cette concentration est dénommée concentration prévue sans effet (PNEC). Toutefois, il se peut que dans certains cas il ne soit pas possible d'établir une PNEC et il faut alors effectuer une estimation qualitative de la relation dose (concentration)-réponse (effet). Pour calculer la PNEC, on peut appliquer un facteur d'évaluation aux valeurs provenant des essais effectués sur les organismes, par exemple à la DL50 (dose létale médiane), à la CL50 (concentration létale médiane), à la CE50 (concentration effective médiane), à la CI50 (concentration provoquant cinquante pour cent d'inhibition d'un paramètre donné, par exemple la croissance), au NOEL(C) (dose (concentration) sans effet observé), au LOEL(C) (dose (concentration) entraînant l'effet observé le plus faible) ou d'autres méthodes appropriées.
