(author)One of the challenges in river flow simulation modelling is increasing the accuracy of forecasts. This paper explores the complementary use of data-driven models, e.g. artificial neural networks (ANN) to improve the flow simulation accuracy of a semi-distributed process-based model. The IHMS-HBV model of the Meuse river basin is used in this...journal article 2009

(author)This study reports on a comparative investigation of the corrosion behavior of zinc (Zn) and nano-composite zinc (ZnC) galvanic layers in 5% NaCl solution. The metallic matrix of the ZnC layers incorporates nano-sized, stabilized polymeric aggregates, formed from the amphiphilic tri-block co-polymer: poly(2-hydroxyethyl methacrylate) - poly ...journal article 2008

(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).

Degradation of myocardial perfusion SPECT images caused by contaminants in thallous (201Tl) chlorideStaelens, S.G. (author), De Wit, T.C. (author), Lemahieu, I.A. (author), Beekman, F.J. (author)Purpose Thallous (201Tl) chloride is a single-photon emission computed tomography (SPECT) tracer mainly used for assessing perfusion and viability of myocardial tissue. 201Tl emits X-rays around 72 keV and gammas at 167 keV, and has a half-life of 73 h. Regulations allow an intrinsic contamination up to 3–5%, which is mainly caused by 200Tl (368...journal article 2008

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

Zhan, H. (author), Mol, J.M.C. (author), Terryn, H.A. (author), De Wit, J.H.W. (author)Application prospects in automotive and aerospace industry have led to extensive studies on AA6xxx alloys in recent years because of their attractive combinations of properties. The benefits include formability, weldability, high strength to weight ratio and low cost. The main alloying elements in the commercial AA6xxx are Mg, Si, Fe and Cu. Mg...journal article 2007
