Among workers 60 64 years of age at entry, the risk was elevated only in the conductor group but not statistically significantly.
Because 8 kHz is central to all definitions of audiometric notches, this small difference probably explains the occurrence of more notches in the train driver and conductor group than in the reference group, despite the small difference in hearing between the groups and the reference group.
In our retrospective cohort study of 54,973 railroad workers, we also observed a similarly elevated relative risk (RR) of 1.41 (95% CI, 1.27 1.55) for COPD mortality between 1959 and 1996, comparing workers in the engineer and conductor group in 1959 with workers in the unexposed group (Garshick et al. 2004).
Hazard ratios (referred to as RRs) and 95% CIs are presented separately for engineers, conductors, and shop worker groups and for the engineer and conductor groups combined compared with unexposed workers based on job code on entry into the study in 1959.
The association of lung cancer mortality with duration of exposure as a surrogate for cumulative dose was assessed as a time-varying covariate, based on yearly job code and service months, starting in 1959 in the combined engineer and conductor groups, and was grouped in 5-year exposure categories.
This measurement of conductor preload results in minimising any associated uncertainties, assumptions and the corresponding over-conservatisms carried over from the design stage, hence streamlining the repair and rehabilitation strategies to the most critical well-conductor groups in the field, thus significantly reducing the costs and resources for operators in extending life of aged wells.
Cable, in electrical and electronic systems, a conductor or group of conductors for transmitting electric power or telecommunication signals from one place to another.
On a good night with the Fall, Smith acts like a lightning conductor to group and audience.
Correction: December 14 , 2002 Saturday An obituary on Dec. 1 about Noel Regney, who wrote the Christmas song "Do You Hear What I Hear?" misspelled the surname of the chorale arranger and conductor whose group recorded it.
Performing without conductor, the group is vibrantly led from the violin by Richard Tognetti, but the excellent contributions from many individuals, right down to the characterful double-bassist, made the lack of a listing seem unjust.
Led by Kristjan Jarvi, its rock star conductor, the group is on a current tour that features bold re-imaginings in a program called "Absolute Bach Re-invented," which they performed with the pianist Simone Dinnerstein for a large and enthusiastic crowd at Le Poisson Rouge on Friday evening.
