(author)In order to sustain human life for extended periods of time in deep space one cannot solely rely on support from Earth. It'll be essential to become self-sustaining through a combination of in situ resource utilization, waste recycling, and space farming. The latter can provide astronauts and colonists with locally grown food and biogenic...journal article 2019

Felz, S. (author), Vermeulen, Pascalle (author), van Loosdrecht, Mark C.M. (author), Lin, Yue Mei (author)Biofilm structure and functionality depend on extracellular polymeric substances (EPS), but analytical methods for EPS often lack specificity which limits progress of biofilm research. EPS were extracted from aerobic granular sludge and analyzed with frequently applied colorimetric methods. The colorimetric methods were evaluated based on...journal article 2019

(author), Van Der Wal, Maarten (author)Longitudinal training dams (LTDs) are a promising alternative for river groynes. Here we summarize findings of a recent study focused on the along river transition from a series of river groynes to an LTD, where the flow divides between the fairway and the side channel between the LTD and the river bank. A scale model is setup using...journal article 2018

Vermeulen, B. (author), Pyka, A. (author), la Poutré, J.A. (author), de Kok, A.G. (author)In recent literature, there is disagreement over the temporal pattern of vertical governance of firms over the product life-cycle. We use a novel neo-Schumpeterian agent-based simulation model to investigate emerging patterns of vertical governance for different levels of imitability and substitutability of capabilities.

(author)Background Resuscitation at birth with 100% oxygen is known to increase the oxidative burden with concomitant deleterious effects. Although fractions of inspired oxygen (FiO2)?<?100% are widely used in preterm infants, starting resuscitation at a (too) low FiO2 may result in hypoxia. The objective of this study is to compare the safety and...journal article 2012
