(author)This paper reports on the corrosion performance of composite zinc layers (~ 8µm) on a steel substrate, considering the influence of nano-aggregates and Cr(III) conversion layers, compared to control (only Zn layers) conditions. The main factors, influencing the corrosion performance of Zn in this study are: a) the effect of two concentrations of...journal article 2011

(author), Zonneneberg, B.A. (author), Van den Ingh, T.S.G.A.M. (author), Van het Schip, A.D. (author)Purpose The aim of this study is to evaluate the toxicity of holmium-166 poly(l-lactic acid) microspheres administered into the hepatic artery in pigs. Methods Healthy pigs (20–30 kg) were injected into the hepatic artery with holmium-165-loaded microspheres (165HoMS; n?=?5) or with holmium-166-loaded microspheres (166HoMS; n?=?13). The...journal article 2008

De Wit, S.I. (author)The term genius loci—“the prevailing character or atmosphere of a place,” as the Oxford English Dictionary defines it—has long been used to interpret landscape characteristics. Lately, however, it is being used, and abused, as a justification in just about any discourse. For spatial, aesthetic, and ecological discussions and social, cultural,...journal article 2011

Koleva, D.A. (author), Van Breugel, K. (author), Boshkov, N. (author), Mol, J.M.C. (author), De Wit, J.H.W. (author)This work reports on monitoring chloride-induced corrosion in reinforced mortar specimens, with and without addition of polymeric nano-aggregates in the mortar mixture. The investigation is a novel approach to control steel corrosion in reinforced concrete, hereby reporting the preliminary results, related to one of the main objectives: studying...journal article 2010

(author)Bij het werken aan historische tuinen heeft de landschapsarchitect niet alleen te maken met de vele tijdslagen die een ontwerp hebben veranderd in wat het nu is – ook andere disciplines spreken zich uit over de waarde en waardevolle elementen die er in voorkomen. Dat leidt tot soms starre voorschriften die de objecten geen goed doen. Een...journal article 2011

Koleva, D.A. (author), Van Breugel, K. (author), De Wit, J.H.W. (author), Fraaij, A.L.A. (author), Boshkov, N. (author)The present study explores the formation of corrosion products on the steel surface in reinforced concrete in conditions of corrosion and subsequent transformation of these layers in conditions of cathodic protection (CP). Of particular interest was to investigate if the introduced pulse CP (as cost- effective alternative of CP) will lead to...journal article 2007

Radermacher, M. (author), Van der Goot, F. (author), Rijks, D.C. (author), De Wit, L. (author)One of the potential environmental issues associated with dredging in the marine environment is the increase of suspended sediment concentrations (SSC) by generation and dispersion of sediment plumes. This can be mitigated by source control or by the installation of containment barriers like silt screens. This article focusses on hanging silt...journal article 2013

Tu, H. (author), Tamminga, G.F. (author), De Wit, J. (author), Van der Berg, W. (author)The evacuation clearance time is one of the key indicators in an evacuation plan and is determined by the expected behavior of the endangered residents and roadway network characteristics. The city of Almere has developed an evacuation plan in case of the emergency of a flooding, but assumes a normal driving behavior of the evacuees. In this...journal article 2010
