INDEX MATURITY [7 records]

Record 1 2020-06-04

English

Subject field(s)
  • Animal Biology
  • Fish
CONT

The gonadosomatic index, abbreviated as GSI, is the calculation of the gonad mass as a proportion of the total body mass... It is a tool for measuring the sexual maturity of animals in correlation to ovary development and testes development.

French

Domaine(s)
  • Biologie animale
  • Poissons
CONT

L'indice gonadosomatique […], révélateur du potentiel reproducteur des poissons, a été calculé par le rapport : (poids des gonades / (poids corporel total - poids des gonades)) x 100.

Key term(s)
  • indice gonado-somatique

English

Subject field(s)
  • Geochemistry
DEF

A measure of the progress of a clastic sediment in the direction of chemical or mineralogic stability.

OBS

For example, a high ratio of quartz + cherts to feldspar + rock fragments indicates a highly mature sediment.

Key term(s)
  • index of maturity

French

Domaine(s)
  • Géochimie
CONT

On établit un «index de maturité» qui exprime la différence qui existe entre le dépôt final sédimenté et la roche primitive broyée.

English

Subject field(s)
  • Biological Sciences
  • Agriculture - General
CONT

There were significant differences between varieties, while no significant interaction was found between planting method and variety. On the other hand, transplanting seedling increased the number of days to flowering, number of days to maturity, panicle length, number of fertile tillering, number of spikelet per panicle, number of grain per panicle, 1000-seed weight, harvest index, hectoliter weight, brown rice width, total milled rice, alkali digestion degree, while it decreased plant height, the number of panicle/m², sterility and biological yield.

Domaine(s)
  • Sciences biologiques
  • Agriculture - Généralités
CONT

Pour se développer, les plantes ont besoin d'eau et d'éléments minéraux, notamment d'azote. Mais la majeure partie de cet azote n'est pas directement consommable par les végétaux. Cette matière organique doit auparavant être transformée par les organismes vivants du sol, d'où la notion de fonctionnement biologique des sols. Cette fonction est remplie par une diversité d'organismes dont les plus actifs sont les bactéries, les champignons et les actinomycètes. Comme pour tous les organismes vivants, leurs efficacité dépend très étroitement de la quantité de matière organique dont ils se nourrissent et de la qualité de l'environnement, ici le sol, dans lequel ils travaillent (humidité, aération etc...). Le «rendement biologique» d'un sol peut être amélioré par des apports de matière organique, des périodes de jachère et un travail du sol adapté.

Record 5 2000-12-18

English

Subject field(s)
  • Chemical Elements and Compounds
DEF

The ratio of the amounts of odd-carbon n-alkanes to those of even-carbon n-alkanes.

CONT

Carbon Preference Index(CPI). Generally the ratio of abundance of odd over even carbon number paraffins, specifically calculated over the C24-C34 range. Hydrocarbons derived predominantly from terrestrial sources and/or at low maturity exhibit a predominance of odd-numbered alkanes(resulting in a high CPI) ;this feature disappears with increasing maturation level(CPI approaches 1. 0).

CONT

... case studies show that in ancient detrital sediment the predominance of the original odd n-alkanes of high molecular weight is preserved mainly in relatively shallow shales and silts, where degradation of kerogen has not yet started... With increasing maturity, and odd-even preference(also known as CPI : carbon preference index) of about 5 : 1 in shallow detrital material is reduced to around unity in the zone of oil formation, as a result of thermal degradation and the introduction of new alkanes, which dilutes the original odd-even predominance.

French

Domaine(s)
  • Éléments et composés chimiques
DEF

Quotient des alcanes en chaîne droite ayant un nombre impair d'atomes de carbone et des alcanes en chaîne droite ayant un nombre pair d'atomes de carbone.
