(author), Dusek, U. (author)Radiocarbon analysis is a widely-used tool for source apportionment of aerosol particles. One of the big challenges of this method, addressed in this work, is to isolate elemental carbon (EC) for 14C analysis. In the first part of the study, we validate a two-step method (2stepCIO) to separate total carbon (TC) into organic carbon (OC) and EC...article 2017

Traversari, A.A.L. (author), Bottenheft, C. (author), van Heumen, S.P.M. (author), Goedhart, C.A. (author), Vos, M.C. (author)Background: Switching off air handling systems in operating theaters during periods of prolonged inactivity (eg, nights, weekends) can produce a substantial reduction of energy expenditure. However, little evidence is available regarding the effect of switching off the air handling system during periods of prolonged inactivity on the air quality...article 2016

(author), van der Klink, J.J.L. (author)In this cross-sectional study associations were examined between eight shift schedule characteristics with shift-specific sleep complaints and need for recovery and generic health and performance measures. It was hypothesized that shift schedule characteristics meeting ergonomic recommendations are associated with better sleep, need for recovery...article 2016

(author), Bültmann, U. (author)This study examined associations of chronotype and age with shift-specific assessments of main sleep duration, sleep quality and need for recovery in a cross-sectional study among N = 261 industrial shift workers (96.6% male). Logistic regression analyses were used, adjusted for gender, lifestyle, health, nap behaviour, season of assessment and...article 2016

Tajdari, F. (author), Berkhoff, A.P. (author), de Boer, A. (author)The present work describes the electrical, mechanical and acoustical behavior of a thin honey-comb structure as an acoustic source. The acoustic source has to operate in the low frequency, quasi-static regime and is driven by a piezoelectric stack actuator. In addition, a two-way energy flow between the actuator and a connected amplifier is...conference paper 2016

(author)Study Design Prospective cohort design using data derived from usual care. Background It is important that patients are able to function independently as soon as possible after total hip replacement. However, the speed of regaining activities differs significantly. Objectives To develop a risk stratification model (RSM) to predict delayed...article 2016

Lueks, W. (author), Everts, M.H. (author), Hoepman, J.H. (author)Service providers are often reluctant to support anonymous access, because this makes it hard to deal with misbehaving users. Anonymous blacklisting and reputation systems can help prevent misbehaving users from causing more damage. However, by the time the user is blocked or has lost reputation, most of the damage has already been done. To help...conference paper 2016

Niks, I.M.W. (author), Gevers, J.M.P. (author), de Jonge, J. (author), Houtman, I.L.D. (author)It is well-known that recovery from work and job resources can counteract negative effects of high job demands, but less is known about how off-job recovery and job resources are related to each other. In this two-level daily diary study, 67 employees filled out daily surveys over the course of 8 days to examine this issue. Consistent with our...article 2016

(author)Background: To recover from work stress, a worksite health program aimed at improving physical activity and relaxation may be valuable. However, not every program is effective for all participants, as would be expected within a "one size fits all" approach. The effectiveness of how the program is delivered may differ across individuals. The aim...article 2016

Klimkowski, Ł. (author), Nagy, S. (author), Papiernik, B. (author), Orlic, B. (author), Kempka, T. (author)Natural gas from the Załęcze gas field located in the Fore-Sudetic Monocline of the Southern Permian Basin has been produced since November 1973, and continuous gas production led to a decrease in the initial reservoir pressure from 151 bar to about 22 bar until 2010. We investigated a prospective enhanced gas recovery operation at the Załęcze...article 2015

Muller, C. (author), Maldonado, A.G. (author), Varnek, A. (author), Creton, B. (author)Each oil reservoir could be characterized by a set of parameters such as temperature, pressure, oil composition, and brine salinity, etc. In the context of the chemical enhanced oil recovery (EOR), the selection of high performance surfactants is a challenging and time-consuming task since this strongly depends on the reservoir's conditions.

Leeuwenburgh, O. (author), Hofstee, C. (author), Wilschut, F. (author)The displacement of heavy oil by water flooding is characterized by instable features known as viscous fingers. These fingers may form at very small scales, as can be observed in laboratory experiments and predicted from instability theory. Explicit representation of such features in large-scale reservoir models is practically impossible because...conference paper 2015
