Austin, P.C. (author), White, I.R. (author), Lee, D.S. (author), van Buuren, S. (author)Missing data is a common occurrence in clinical research. Missing data occurs when the value of the variables of interest are not measured or recorded for all subjects in the sample. Common approaches to addressing the presence of missing data include complete-case analyses, in which subjects with missing data are excluded, or mean-value...article 2021

Veraar, R.G. (author), Wieling, W.P.W. (author)Solid Fuel Ramjet (SFRJ) technology is a very attractive propulsion option to extend the range of gun launched projectiles mainly due to the combination of high specific impulse inherent to airbreathing propulsion and mechanical properties of the solid fuel capable of withstanding the very high launch loads in the gun. In 2004, the Netherlands...conference paper 2018

Vakili, V. (author), Brinkman, W.P. (author), Morina, N. (author), Neerincx, M.A. (author)In the last two decades, several effective virtual reality-based interventions for anxiety disorders have been developed. Virtual reality interventions can also be used to build resilience to psychopathology for populations at risk of exposure to traumatic experiences and developing mental disorders as a result, such as for people working in...article 2014

Beurskens-Comuth, P.A.W.V. (author), Verbist, K. (author), Brouwer, D. (author), TNO Kwaliteit van Leven (author)Objectives: There is a growing awareness of the potential risks for human health of exposure to ultrafine particles or nanoparticles. In that context, workplace air measurements become important, and various strategies have been developed to monitor exposure. In addition, observations and time/activity registrations are part of the exposure...article 2011

(author), TNO Kwaliteit van Leven (author)Previously, the contact allergen dinitrochlorobenzene (DNCB) was identified as a sensitizer by inhalation in BALB/c mice; in addition, DNCB induced a lymphocytic infiltrate in the larynx of dermally sensitized Th1-prone Wistar rats upon a single inhalation challenge. In the present study, repeated inhalation exposures to DNCB were investigated...article 2010

(author), TNO Kwaliteit van Leven (author)Purpose: The prevalence of asthma symptoms among preschool children is difficult to determine with accuracy because no gold standard is available for diagnosis. The aim of this study was to compare parent-reported wheezing or shortness of breath among infants as assessed by questionnaire and physician-interview. Methods: We studied 1,202...article 2010

Normal breathing frequency is close to this frequency. There is some evidence for synchronization of breathing with this stimulus frequency. If this enforced breathing takes place over a larger frequency range (0.05-0.8 Hz) and whether this contributes...article 2009

Mert, A. (author), Bles, W. (author), Nooij, S.A.E. (author), TNO Defensie en Veiligheid (author)Introduction: In motion sickness desensitization programs, the motion sickness provocative stimulus is often a forward bending of the trunk on a rotating chair, inducing Coriolis effects. Since respiratory relaxation techniques are applied successfully in these courses, we investigated whether these repetitive trunk movements by themselves may...article 2007
