PARTICULATE ANALYSIS [7 records]

Record 1 2013-12-11

English

Subject field(s)
  • Medical Imaging
CONT

Single Particle Analysis is a group of related computerized image processing techniques used to analyze images from transmission electron microscopy(TEM). These methods were developed to improve and extend the information obtainable from TEM images of particulate samples, typically proteins or other large biological entities such as viruses. Individual images of stained or unstained particles are very noisy, and so hard to interpret. Combining several digitized images of similar particles together gives an image with stronger and more easily interpretable features. An extension of this technique uses single particle methods to build up a three dimensional reconstruction of the particle.

Domaine(s)
  • Imagerie médicale
CONT

L'analyse de particules isolées est une méthode de microscopie électronique en transmission (MET) permettant l'étude de la structure d'assemblages macromoléculaires in vitro (p. ex. protéines, ribosomes, virus).

  • Solid Fossil Fuels
CONT

Maceral analysis can be made on blocks of coal cut vertically to the bedding plant representing column sections of seams and on representative samples of particulate coal.

French

Domaine(s)
  • Combustibles fossiles solides
CONT

L'analyse macérale consiste à déterminer la proportion des principaux constituants en balayant l'échantillon [...] L'opérateur définit le macéral qui se trouve au centre du réticule et totalise sa fréquence d'apparition. La norme préconise 500 prélèvements pour estimer la proportion des différents macéraux, à savoir essentiellement l'exinite, la vitrinite, la fusinite, la semi-fusinite et l'inertinite.

CONT

L'analyse macérale d'un charbon peut être établie, soit à partir d'un pilier de veine perpendiculaire à la stratification, soit à partir d'un échantillon granulaire moyennement représentatif. L'on utilise la méthode de comptage par points.

CONT

High levels of zinc deposition from the stack dust has decimated the landscape along parts of the Appalachian Trail that skirt the smelter.

CONT

However, analysis of stack dust from one of the nickel-copper smelters in the Sudbury area by Cox and Hutchinson(1981) indicated that 77% of the particulate nickel was in water-soluble forms.

CONT

Toutefois, une analyse de la poussière de cheminée d'une des fonderies de nickel-cuivre situées dans la région de Sudbury, effectuée par Cox et Hutchinson (1981), a indiqué que 77 % du nickel particulaire se trouvait sous des formes solubles dans l'eau.

Subject field(s)
  • Dust Removal
CONT

Dust and particulate collector. Particulates from a paint application and especially from a spray booth, can be of major concern....

CONT

General techniques for gas sensors and air quality monitors. Wetted surface high efficiency atmosphere particulate collector. A variety of instruments have been devised over the years for the collection of particulates for off-line analysis. These include membrane filters, impactors, elutriators and centrifuges. Each has its own advantages and disadvantages, but one key disadvantage that they all share is that their efficiency varies according to the size of the particles.

PHR

Advanced hybrid particulate collector (AHPC), flue gas particulate collector, high efficiency atmosphere particulate collector.

CONT

Recueillir et analyser les particules en suspension dans l'atmosphère : - fabriquer un collecteur de particules avec une bande de carton de 5 x 25 cm perforée de 5 trous de 2,5 cm de diamètre; coller une bande de ruban adhésif transparent sur l'une des surfaces en couvrant les trous. Le côté adhésif du ruban recueillera les particules présentes dans l'air. Mettre le collecteur témoin à l'abri de toute poussière.

PHR

Collecteur de particules atmosphériques, collecteur de particules humides.

Record 7 1986-05-09

English

Subject field(s)
  • General Mechanics (Physics)
CONT

During transport through the soil, sulphuric acid can dissolve some of the soil material, in particulate carbonate-based materials. The acid will be neutralized to some degree. However, significant amounts of acid are expected to remain for transport down toward the groundwater table. The analysis used here neglects these retarding factors.

OBS

"retarding potential" (phys): A potential which causes the speed of a moving particle to be reduced.

French

Domaine(s)
  • Mécanique générale (Physique)
OBS

L'adjectif "retardateur" serait le plus approprié mais il a été rejeté pour des raisons phoniques : "facteur retardateur" choque l'oreille.

OBS

"retardateur, trice", adj. : Qui retarde, ralentit un mouvement. (Phys). "Force retardatrice" (...) "Potentiel retardateur".

OBS

"freinage" : Action de créer une force retardatrice. (source : LAROG); "force de freinage" : terme relevé dans DORSC.
