(author)Objectives: Exposure-outcome studies, for instance on work-related low-back pain (LBP), often classify workers into groups for which exposures are estimated from measurements on a sample of workers within or outside the specific study. The present study investigated the influence on bias and power in exposure-outcome associations of the sizes of...article 2015

(author), Stuerwald, S. (author)A comparison of topography measurements of aspherical surfaces was carried out by European metrology institutes, other research institutes and a company as part of an European metrology research project. In this paper the results of this comparison are presented. Two artefacts were circulated, a small polymer coated aspherical lens with a clear...article 2015

Brouwer, D.H. (author), Lidén, G. (author), Asbach, C. (author), Berges, M. (author), van Tongeren, M. (author)The production of nanomaterials and nano-enabled products is associated with the potential for workers' exposure to (manufactured) nano-objects' agglomerates and aggregates (NOAA). Workplace air monitoring studies have been conducted to assess the actual exposure; however, the methods and strategies applied to measure concentrations of NOAA in...bookPart 2014

van Wendel de Joode, B. (author), Brouwer, D.H. (author), Kromhout, H. (author), van Hemmen, J.J. (author), TNO Voeding (author)This paper describes a new method (DREAM) for structured, semi-quantitative dermal exposure assessment for chemical or biological agents that can be used in occupational hygiene or epidemiology. It is anticipated that DREAM could serve as an initial assessment of dermal exposure, amongst others, resulting in a ranking of tasks and subsequently...article 2003
