Work Stress in Norwegian Trawler Fishermen

The regular patterns of activity as well as the average energy expenditure were quite similar in the two trawlers examined and there was a high degree of reproducibility in the circulatory strain in the same subject in different on-duty shifts.

Abstract

The authors have realised vertically tapered and antireflection-coated waveguides in InP/InGaAsP with 1.7 dB coupling loss and relaxed alignment tolerances to lensed single-mode fibres with spot diameters of 3.8 mu m. The waveguide tapers are fabricated by a dip-etch process that is well suited for integration with optical waveguide circuits
