Ter Brake, M.C. (author), Schuttelaars, H.M. (author)In many tidal embayments, bottom patterns, such as the channel-shoal systems of the Wadden Sea, are observed. To gain understanding of the mechanisms that result in these bottom patterns, an idealized model is developed and analyzed for short tidal embayments. In this model, the water motion is described by the depth- and width-averaged shallow...journal article 2009

Sorokin, D.Y. (author), Muyzer, G. (author)A possibility of dissimilatory MnO2 reduction at extremely high salt and pH was studied in sediments from hypersaline alkaline lakes in Kulunda Steppe (Altai, Russia). Experiments with anaerobic sediment slurries demonstrated a relatively rapid reduction of colloidal MnO2 in the presence of acetate and formate as electron donor at in situ...journal article 2009

Blinde, P.L. (author), Humble, R.A. (author), Van Oudheusden, B.W. (author), Scarano, F. (author)Stereoscopic particle image velocimetry is used to investigate the effects of micro-ramp sub-boundary layer vortex generators, on an incident shock wave/boundary layer interaction at Mach 1.84. Single- and double-row arrangements of micro-ramps are considered. The micro-ramps have a height of 20% of the unperturbed boundary layer thickness and...journal article 2009

Bakker, M. (author)A new analytic-element solution is presented for a well with a sinusoidal discharge pumping near cylindrical inhomogeneities. Both the transmissivity and the storage coefficient may be different inside each cylinder. The solution consists of separate series solutions inside and outside each cylinder; asymptotic expansions are presented for cases...journal article 2009

Zhou, J. (author), Qian, S. (author), Sierra Beltran, M.G. (author), Ye, G. (author), Van Breugel, K. (author), Li, V.C. (author)Nowadays limestone powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete, since the production of these two materials needs less energy and causes less CO2 emission than Portland cement...journal article 2009

Wijntjes, M.W.A. (author), Kappers, A.M.L. (author)It is known that our senses are influenced by contrast effects and aftereffects. For haptic perception, the curvature aftereffect has been studied in depth but little is known about curvature contrast. In this study we let observers explore two shapes simultaneously. The shape felt by the index finger could either be flat or convexly curved. The...journal article 2009

Haverkort, J.W. (author), Kenjeres, S. (author), Kleijn, C.R. (author)The aim of Magnetic Drug Targeting (MDT) is to concentrate drugs, attached to magnetic particles, in a specific part of the human body by applying a magnetic field. Computational simulations are performed of blood flow and magnetic particle motion in a left coronary artery and a carotid artery, using the properties of presently available...journal article 2009

Picoreanu, C. (author), Katuri, K.P. (author), Van Loosdrecht, M.C.M. (author), Head, I.M. (author), Scott, K. (author)Derivation of a mathematical model for microbial fuel cells (MFC) with suspended biomass and added electron-transfer mediator is described. The model is based on mass balances for several dissolved chemical species such as substrate, oxidized mediator and reduced mediator. Biological, chemical and electrochemical reactions can occur in the bulk...journal article 2009

Bakker, M. (author)A new accurate numerical solution is presented for aquifer storage and recovery (ASR) systems in coastal aquifers; flow is approximated as radial Dupuit interface flow. The radial velocities of points on the interface are a function of time, the vertical coordinate, and the dimensionless parameter D (the discharge of the well divided by the...journal article 2009

Van Langh, R. (author), Lehmann, E. (author), Hartmann, S. (author), Kaestner, A. (author), Scholten, F. (author)Until recently fabrication techniques of Renaissance bronzes have been studied only with the naked eye, microscopically, videoscopically and with X-radiography. These techniques provide information on production techniques, yet much important detail remains unclear. As part of an interdisciplinary study of Renaissance bronzes undertaken by the...journal article 2009

Merzari, E. (author), Ninokata, H. (author), Mahmood, A. (author), Rohde, M. (author)Geometries containing a narrow gap are characterized by strong quasi-periodical flow oscillations in the narrow gap region. The above mentioned phenomena are of inherently unstable nature and, even if no conclusive theoretical study on the subject has been published, the evidence shown to this point suggests that the oscillations are connected...journal article 2009

Verhagen, S. (author), Retscher, G. (author), Santos, M.C. (author), Ding, X.L. (author), Gao, Y. (author), Jin, S.G. (author)GNSS, InSAR and LIDAR are identified as important techniques when it comes to monitoring and remote sensing of our planet Earth and its atmosphere. In fact, these techniques can be considered as key elements of the Global Geodetic Observing System. Examples of applications are: environmental monitoring; volcano monitoring, land slides, tectonic...conference paper 2009

Gunter, B.C. (author), Wittwer, T. (author), Stolk, W. (author), Klees, R. (author), Ditmar, P. (author)In this study we address the question of whether regional gravity field modeling techniques of GRACE data can offer improved resolution over traditional global spherical harmonic solutions. Earlier studies into large, equatorial river basins such as the Amazon, Zambezi and others showed no obvious distinction between regional and global...conference paper 2009

(author)Gram-positive bacteria capable of nitrogen fixation were obtained in microoxic enrichments from soda soils in south-western Siberia, north-eastern Mongolia, and the Lybian desert (Egypt). The same organisms were obtained in anoxic enrichments with glucose from soda lake sediments in the Kulunda Steppe (Altai, Russia) using nitrogen-free alkaline...journal article 2009

Odijk, D. (author), Verhagen, S. (author), Teunissen, P.J.G. (author)The goal of Network RTK is to provide users with precise ionospheric corrections in order to conduct fast GPS ambiguity resolution and to get cm-level positioning results over medium-distance baselines. In this paper it is shown that a Network RTK user should apply the ratio test with fixed failure rate, having a threshold value that depends on...conference paper 2009

(author)The so-called Colombo-Nyquist (Colombo, The global mapping of gravity with two satellites, 1984) rule in satellite geodesy has been revisited. This rule predicts that for a gravimetric satellite flying in a (near-)polar circular repeat orbit, the maximum resolvable geopotential spherical harmonic degree (lmax) is equal to half the number of...conference paper 2009

Giorgi, G. (author), Teunissen, P.J.G. (author), Verhagen, S. (author), Buist, P.J. (author)GNSS Attitude Determination is a valuable technique for the estimation of platform orientation. To achieve high accuracies on the angular estimations, the GNSS carrier phase data has to be used. These data are known to be affected by integer ambiguities, which must be correctly resolved in order to exploit the higher precision of the phase...conference paper 2009

Koepsell, D.R. (author)Much of the discussion regarding nanotechnology centers around perceived and prosphesied harms and risks. While there are real risks that could emerge from futuristic nanotechnology, there are other current risks involved with its development, not involving physical harms, that could prevent its full promise from being realized. Transitional...journal article 2009
