Subject field(s)
  • Industrial Techniques and Processes
  • Food Industries
  • Water Treatment (Water Supply)
  • Microbiology and Parasitology
DEF

A technique for removing or concentrating particles including micro-organisms(but not free viruses) from fluids by filtration through a filter of known pore size.

CONT

The major applications of membrane filtration in the juice industry are for clarification and concentration. Several ultrafiltration (UF) systems have been installed to clarify apple juice, and systems are also in place for pears, peaches, cranberries and grapes. Besides the elimination of diatomaceous earth filter aid, membrane clarification typically provides 96% to 98% juice recovery ...

OBS

The technique has various physico-chemical and micro-biological applications, such as the "sterilization" of liquids and gases and the separation of micro-organisms from free viruses for their separate examination and/or quantitative assessment.

OBS

membrane filtration: term and definition standardized by ISO.

French

Domaine(s)
  • Techniques industrielles
  • Industrie de l'alimentation
  • Traitement des eaux
  • Microbiologie et parasitologie
DEF

Technique d'élimination ou de concentration des particules des fluides, incluant les micro-organismes (mais non les virus libres), par filtration à travers un filtre de porosité connue.

OBS

La technique a de multiples applications physico-chimiques et microbiologiques, telles que la «stérilisation» de liquides et de gaz et la séparation des micro-organismes des virus libres pour leur examen séparé et/ou leur évaluation quantitative.

OBS

filtration sur membrane : terme et définition normalisés par l'ISO.

DEF

Técnica para eliminar o concentrar partículas, incluidos microorganismos (pero no virus libres) de los fluidos mediante filtración a través de un filtro de tamaño de poro conocido.

OBS

La técnica tiene diversas aplicaciones fisicoquímicas y microbiológicas, tales como la "esterilización" de líquidos y gases y la separación entre microorganismos y virus libres para examinarlos por separado, para evaluación cuantitativa, o ambos.

Record 4 2007-09-28

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

An isothermal snowpack(or any part of a given snowpack deemed isothermal) is 0°C throughout, has free water at all depths, and contributes to the snowmelt hydrograph of its given basin.... An isothermal snowpack is the result of melt metamorphism... This process is initiated by the introduction of liquid water into the snowpack(either from snowmelt or rainfall), which can be distributed to the full-depth of the snowpack by the propagation of water through pore spaces and along strata within the snow structure...

CONT

In much of British Columbia, we now have an isothermal, weak (0°C, wet) snowpack at some amazing elevations. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

The term "isothermal snowcover" is rarely used in avalanche bulletins.

OBS

isothermal snowpack; isothermal snowcover: terms officially approved by the Avalanche Bulletin Terminology Standardization Committee.

Key term(s)
  • isothermal snow-pack
  • isothermal snow pack
  • isothermal snow-cover
  • isothermal snow cover

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
CONT

Dans presque toute la Colombie-Britannique, on trouve un manteau neigeux fragile, humide et isotherme (0 °C) à des altitudes surprenantes. [Exemple entériné par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.]

OBS

manteau neigeux isotherme : terme uniformisé par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.

Cadmium can exist in the water column as free ions in pore water as well as bound to other sediment fractions.

CONT

In natural waters, copper undergoes complex reactions and can be present in solution as cupric ions or complexed with inorganic or organic ligands.

French

Domaine(s)
  • Éléments et composés chimiques
CONT

Le cadmium peut exister sous forme d'ions libres dans l'eau interstitielle ou complexé à d'autres fractions des sédiments.

CONT

Dans les eaux naturelles, le cuivre est l'objet de réactions complexes et peut être présent en solution sous forme ionique ou complexé à des ligands organiques ou inorganiques.

Record 6 1989-12-18

English

Subject field(s)
  • Biological Sciences
CONT

The gel entrapment method involves entrapping of the enzymes within the interstitial spaces of crosslinked water insoluble polymer gels.... The usual method of gel formation is to polymerize acrylamide in an aqueous solution of the soluble enzyme and a crosslinking agent such as N, N-methylenebis(acrylamide). The resulting gel block can be mechanically dispersed into particles of desired size. The broad distribution of pore size of the gel inevitably results in leakage of the entrapped enzyme even after prolonged washing whilst the generation of free radicals in the course of the reaction may affect the activity of the entrapped enzymes.

OBS

See record "entrapment".

French

Domaine(s)
  • Sciences biologiques
CONT

Les enzymes sont en général immobilisées soit par fixation covalente sur un support membranaire, soit par utilisation d'un agent de pontage qui provoque la réticulation des molécules de protéine active ou la coréticulation de l'enzyme avec une protéine inerte. Les techniques d'inclusion dans un gel ou de confinement d'enzymes en solution sont progressivement remplacées pas les méthodes chimiques d'immobilisation. Les capteurs sont le plus souvent de type électrochimique.
