We measured inhalable, thoracic, and so-called "total" wood dust exposure in British Columbia lumber mill workers. Particle-size selective sampling was conducted using the GSP and Seven hole inhalable samplers, the PEM thoracic sampler and the 37-mm

In a lumber mill in the northern inland region of British Columbia, Canada, we measured inhalable particulate, resin acid, and monoterpene exposures, and estimated wood dust exposures. Potential determinants of exposure were documented concurrently,

Micronuclei in peripheral blood lymphocytes from British Columbia seasonal farmworkers and controls were evaluated using the cytokinesis-block technique. The farmworkers harvested berry crops and were likely occupationally exposed to pesticides. Subj

Measurements of the magnetically induced birefringence, linear dichroism, Faraday rotation, Faraday ellipticity and circular dichroism in a cobalt and a magnetite ferrofluid are reported. These results are interpreted in terms of the permittivity ten

The variation with applied magnetic field strength of the apparent parallel and perpendicular dichroism of graphite suspensions of various particle sizes has been measured. The component of the optical absorption that is independent of the state of p

The magnetic birefringence of various samples of Fe3O4 ferrofluids with particle sizes in the range of approximately 8.5-18.5 nm has been measured in field strengths of 5*10-4 to 5*10-1 T. For all the samples it has been found that in low fields the

For pt.I see ibid., vol.12, p.311 (1979). A method is described for measuring the rotary diffusion coefficient of ferrofluid particles, and hence their hydrodynamic size, by observing the decay of their birefringence after a magnetic field pulse. Det
