English

Subject field(s)
  • Statistical Graphs and Diagrams
  • Scientific Research
  • General Medicine, Hygiene and Health
DEF

A scatter diagram in which each point represents a study, relating the estimate of effect and the sample size(or another indicator of the precision of the study).

OBS

In the absence of publication bias, the scatter diagram will form an inverted funnel. A hole in the lower left corner of the funnel indicates the presence of publication bias.

OBS

funnel plot: term and definition standardized by the Health Technology Assessment (HTA) Glossary English Editorial Board and the Translation Bureau.

French

Domaine(s)
  • Diagrammes et graphiques (Statistique)
  • Recherche scientifique
  • Médecine générale, hygiène et santé
DEF

Diagramme de dispersion dans lequel chaque point représente une étude, mettant en relation l’estimation de l’effet et la taille de l’échantillon (ou un autre indicateur de la précision de l’étude).

OBS

En l’absence de biais de publication, le nuage de points formera un entonnoir renversé. Un trou dans le coin inférieur gauche de l’entonnoir indique la présence d’un biais de publication.

OBS

diagramme en entonnoir; diagramme de dispersion des études : termes et définition normalisés par l'Institut national d'excellence en santé et en services sociaux (INESSS) et le Bureau de la traduction.

Universal entry(ies)
potentia hydrogenii
Latin
DEF

Logarithm of the reciprocal of the hydrogen-ion concentration in a solution (-log10[H+]) used as a measure of the degree of acidity or alkalinity of this solution.

CONT

Roughly, pH can be divided into the following ranges: pH 0-2: Strongly acidic; pH 3-5: Weakly acidic; pH 6-8: Neutral; pH 9-11: Weakly basic; pH 12-14: Strongly basic. Under the Controlled Products Regulations, materials with pH values of 0-2 or 11.5-14 may be classified corrosive.

OBS

A pH of 7 is regarded as neutral (pure water), a pH less than 7 corresponds to an acid solution and a pH greater than 7 corresponds to an alkaline solution.

OBS

It should be noted that the pH scale is a logarithmic scale; a substance with a pH of 4 is more than twice as acid as a substance with a pH of 5. Similarly, a substance with a pH of 9 is much more than twice as alkaline as a substance with a pH of 8.

PHR

pH buffer solution, control, decline, diagram, electrode, gradient, indicator, limit, measurement, meter, modifier, probe, range, scale, unit, value.

French

Domaine(s)
  • Unités de mesure et métrologie

potentia hydrogenii
Latin
DEF

Indice exprimant l'activité (ou la concentration) de l'ion hydrogène dans une solution à l'aide d'une échelle logarithmique.

OBS

Si le pH est inférieur à 7, la solution est acide; s'il est supérieur, elle est alcaline.

PHR

valeur de pH.

Entrada(s) universal(es)
potentia hydrogenii
Latin
DEF

Cologaritmo de la concentración de iones hidrógeno en una solución (-log10[H+]) utilizado como medida del grado de acidez o alcalinidad de esta solución.

OBS

Un pH de 7 se considera neutro (agua pura), un pH inferior a 7 corresponde a una solución ácida y un pH superior a 7 a una solución alcalina.

PHR

valor de pH.

Record 3 2000-02-29

English

Subject field(s)
  • Thermodynamics
DEF

Pressure-volume diagram tracing condition of gas in a compressor or engine cycle in terms of pressure and volume displaced.

DEF

A diagram, produced mechanically or electrically, indicating the variations of pressure and volume in the cylinder of a compressor or engine.

Key term(s)
  • indicator chart

French

Domaine(s)
  • Thermodynamique
DEF

Diagramme, relevé mécaniquement ou électriquement, indiquant les variations de pression et de volume dans un cylindre de compresseur ou de moteur.

CONT

Le diagramme d'indicateur, appelé aussi «diagramme de Watt», permet de déterminer le travail indiqué du compresseur frigorifique. C'est le travail que le compresseur effectue sur le fluide frigorigène pendant la durée d'un cycle complet, c'est-à-dire pendant les courses aller et retour du piston.
