(author), TNO Kwaliteit van Leven (author)Aim: The aim of this study was to gain insight into contraception practised and related to breastfeeding duration. Methods: Mothers with infants up to 6 months received a questionnaire on infant feeding (breast or formula feeding) and contraception (hormonal or non-hormonal methods).

Asadi, K. (author), de Boer, T.G. (author), Blom, P.W.M. (author), de Leeuw, D.M. (author), TNO Industrie en Techniek (author)Organic non-volatile resistive bistable diodes based on phase-separated blends of ferroelectric and semiconducting polymers are fabricated. The polarization field of the ferroelectric modulates the injection barrier at the semiconductor-electrode contact and, hence, the resistance of the comprising diodes. Comparison between the on- and off...article 2009

van den Berg, F. (author), van der Eerden, F.J.M. (author), TNO Industry and Science, Acoustics Department, Stieltjesweg 1, 2628 CK Delft, Netherlands (author)Large weapons, such as armor, artillery or demolitions, create a high-energy blast wave. It has a low frequency content, typically between 15 and 125 Hz, and can propagate over large distances. As a result it is a relative important cause for annoyance. Mitigation measures need to be close to the source for best effectiveness, but due to the...conference paper 2007

(author), TNO Kwaliteit van Leven (author)When plastics are collected for recycling, possibly contaminated articles might be recycled into food packaging, and thus the contaminants might subsequently migrate into the food. Multilayer functional barriers may be used to delay and to reduce such migration. The contribution of the work reported here is to establish reference values (at 40°C...article 2006

Dittrich, M.G. (author), van Beek, P.J.G. (author), TNO Industrie en Techniek (author)Road traffic noise is one of the major environmental noise sources that is known to cause health problems. Despite existing noise reception items, the continuing growth of traffic causes higher levels than the lims allow. Consequently, excessive costs are incurred for noise barriers along roads and motorways. It's therefore essential to...conference paper 2006

Often, neither the presence nor the identity of the contaminants is known, so that safety assessment of the materials has to rely on predictive tools...article 2006
