van Berchum, E.C. (author), de Vries, P.A.L. (author), de Kort, R.P.J. (author)The Galveston Bay Area is under significant risk from hurricane induced flooding. Ever since Hurricane Ike caused billions of damage back in 2008, the option of closing off the Galveston Bay from the Gulf of Mexico was investigated. This report, commissioned by Texas A&M University in Galveston, explores the opportunities and options for the...report 2016

Al-Attar, S. (author), Yu, Y. (author), Pinkse, M.W.H. (author), Hoeser, Jo (author), Friedrich, Thorsten (author), Bald, Dirk (author), de Vries, S. (author)Cytochrome bd is a prokaryotic terminal oxidase that catalyses the electrogenic reduction of oxygen to water using ubiquinol as electron donor. Cytochrome bd is a tri-haem integral membrane enzyme carrying a low-spin haem b<sub>558</sub>, and two high-spin haems: b<sub>595</sub> and d. Here we show that besides its oxidase activity,...journal article 2016

Sterlini, Paul (author), de Vries, Hylke (author), Katsman, C.A. (author)Data from 21 years of satellite altimeter measurements are used to identify and understand the major contributing components of sea surface height variability (SSV) on monthly time-scales in the North East Atlantic. A number of SSV drivers is considered, which are categorised into two groups; local (wind and sea surface temperature) and...journal article 2016

(author), Sokolich, Marko (author)A Corbino ring geometry is utilized to analyze edge and bulk conductance of InAs/GaSb quantum well structures. We show that edge conductance exists in the trivial regime of this theoretically predicted topological system with a temperature-insensitive linear resistivity per unit length in the range of 2 kΩ/μm. A resistor network model of the...journal article 2016

Hoonhout, B.M. (author), de Vries, S. (author)Aeolian sediment transport is influenced by a variety of bed surface properties, like moisture, shells, vegetation, and nonerodible elements. The bed surface properties influence aeolian sediment transport by changing the sediment transport capacity and/or the sediment availability. The effect of bed surface properties on the transport capacity...journal article 2016

(author), van Lohuizen, Maarten (author)EZH2 inhibitors have gained great interest for their use as anti-cancer therapeutics. However, most research has focused on EZH2 mutant cancers and recently adverse effects of EZH2 inactivation have come to light. To determine whether colorectal cancer cells respond to EZH2 inhibition and to explore which factors influence the degree of response...journal article 2016

van Breukelen, D.H.J. (author), Michels J, Koen (author), Schure, Frank A. (author), de Vries, M.J. (author)This paper presents a pretest-posttest design study that compares conceptual learning gains of 237 students, divided into two groups, exposed to a modified and remodified Learning by Design (LBD) task. LBD uses design contexts to learn skills and conceptual knowledge where research around the year 2000 showed high skill performances but...journal article 2016

Roël-Looijenga, A. (author), Klapwijk, R.M. (author), de Vries, M.J. (author)One of the core activities of Design and Technology Education is designing, which is a thinking activity that benefits greatly from expression. Verbal expression serves interaction. A teacher can induce verbal expression in pupils by inviting them to interact about familiar subjects. This interaction is a stepping stone towards an integration of...journal article 2017

Wardenier, J. (author), de Vries, P.A. (author), Timmerman, Gerrit (author)This paper is part of an evaluation of fatigue cracks in a crane runway girder with full penetration welds between the web and flange. The fatigue analysis of this actual crane runway girder is described in [1]. The investigation described in this paper deals with additional experimental tests on equivalent welded I sections on scale of...journal article 2017

Cohn, Nicholas (author), Ruggiero, Peter (author), de Vries, S. (author), García-Medina, Gabriel (author)Seasonal variability in wave conditions drive corresponding cycles of erosion and accretion along sandy beaches. Despite the fact that these oscillations are well documented at numerous sites throughout the world, the physical processes driving beach recovery remain poorly understood. Using field data from a low sloping, dissipative beach in the...conference paper 2017

Vos, S.E. (author), Lindenbergh, R.C. (author), de Vries, S. (author)Sandy coasts are vulnerable to predicted climate change, but also need to safeguard coastal housing, recreation, safety and ecology. “Building with Nature” is an important approach for resilient coastal maintenance, but corresponding predictive modelling tools are partly inconclusive, due to a lack of measurements over multiple spatial and...conference paper 2017

de Schipper, M.A. (author), Darnall, John (author), de Vries, S. (author), Reniers, A.J.H.M. (author)Five years of beach topography data were examined to map the spatio-temporal patterns in beach scarp existence. Data of the Sand Engine were used, a mega scale nourishment implemented in 2011 at the Dutch coast. Topographic data were automatically and manually analyzed to recognize scarps in the dataset. Moments of destruction and persistence of...conference paper 2017

de Vries, G. (author)We are shaken almost weekly by reports of the threat of terrorism. But just how real is this threat, and how is it experienced by the general public? It is not unlikely that there is a gap between the threat of terrorism and people's perception of the risk. A new research project by Doctor Gerdien de Vries of TU Delft, in which researchers from...report 2017
