Record 2 2010-02-16

English

Subject field(s)
  • Microbial Ecology
DEF

A small, immobilized bed, microbe bioreactor.

CONT

The bioreactor "plug" is made of slotted PVC pipe which is screw cap sealed at each end. Each plug is loaded with an inert porous material which serves as a structural support matrix for the microorganisms. The seed cultures in the bioplugs are a mixture of microorganisms selected for their abilities to biodegrade the contaminants of concern... The bioplugs are strategically inserted into the contaminated zone(s). Liquids then flow through the plugs by a pressure gradient created using compressed air. This flow acts to accelerate the movement of ground or irrigation water through the immobilized bed; thereby, facilitating the mineralization of organics within the aqueous phase and the bulk generation of biomass which bleeds off the bed.

French

Record 4 1995-04-20

English

Subject field(s)
  • Medical Imaging
CONT

Only two dimensions of a three dimensional object are visible on plain roentgenograms. Therefore, on gross inspection of antero-posterior and lateral roentgenograms, a screw may project as being safely within the head of the femur even though penetration has occurred. This region may be referred to as a "blind zone".

French

Domaine(s)
  • Imagerie médicale
CONT

L'ensemble des points situés à l'extérieur de la sphère (tête fémorale) dont les projections orthogonales se confondent avec celles des points situés à l'intérieur de la sphère constituent donc une zone "aveugle". A l'inverse, les points situés dans la sphère, trop près de la zone sous-chondrale, sont dans une zone dite "d'insécurité radiologique" puisqu'on peut les confondre avec les projections radiologiques des points situés à l'extérieur de la tête fémorale.
