โฆ Synopsis
Dynamic sealing
that require long piston strokes.
Moulded elastomeric diaphragms are tough versatile dynamic seals and have high sensitivity and negligible hysteresis.
The overall industry for moulded diaphragm seals continues to increase significantly --from 5%-7% annually --with most of this growth being attributed to new product uses and expanded market segments. The irrigation market alone already represents a S 1-S2m market opportunity lor DiaCom, with special emphasis on irrigation valves.

Mutations in the cysB and cysE genes of Escherichia coli K12 cause an increase in resistance to the gyrase inhibitor novobiocin but not to coumermycin, acriflavine and rifampicin. This unusual relationship was also observed among spontaneous novobiocin resistant (Novr) mutants: 10% of Novr mutants i
