Dissolution, translocation, and disposition have been shown to play a key role in the fate and effects of inhaled particles and fibers. Concepts that have been applied in the micron size range may be usefully applied to the nanoscale range, but new challenges are presented based on the small size and possible change in the dissolution:translocation(More)
The filtration efficiencies of respirator filters and filtering facepieces have been tested against radon daughters in a fluorspar mine. The test method involved the use of sampling filters exposed to natural radon daughters in air filtered by the test respirators. Respirators with a filtration efficiency high enough for them to be considered suitable for(More)
The protection of apples against damage by the codling moth,Laspeyresia pomonella (L.), by applications of the granulosis virus ofL. pomonella was assessed in apple orchard tests at 4 locations in Canada in 1974–1978. Sprays containing 3×109 to 4×1010 granules/litre, applied 2 or 3 times per generation of codling moth larvae, reduced injury to apples by 44(More)

The antiinflammatory activity of two new steroids synthesized by modifying the 17 beta-ketol side chain of prednisolone to the glycolate and glyoxylate methyl esters has been investigated in the carrageenin pedal edema test in rats. The two ester derivatives retained anti-inflammatory potency, nearly equivalent to that of the parent compound, when(More)
