Magnetic-based purification system with simultaneous sample washing and concentration
Simultaneous washing and concentration of magnetic microparticles was demonstrated using a rotational magnetic system under a continuous-flow condition. The rotation of periodically arranged permanent magnets close to a fluidic channel carrying a suspensio ...
Springer-Verlag2010Toe protection for spill-through and vertical-wall abutments
Anton Schleiss, António Heleno Cardoso
This study addresses the design of riprap aprons as a scour countermeasure near abutments under clear-water conditions. It deals with the lateral extent of riprap aprons and the geometry of the scour hole prevailing at the apron edge. The study applies to ...
2010Taste and odour problems generated in distribution systems: a case study on the formation of 2,4,6-trichloroanisole
A taste and odour (T&O) episode in a Swiss town, where consumers complained about a musty odour in their drinking water, was investigated. The application of a combined organoleptic and instrumental method for T&O analysis allowed the identification of 2,4 ...
2009Simultaneous E-coli inactivation and NOM degradation in river water via photo-Fenton process at natural pH in solar CPC reactor. A new way for enhancing solar disinfection of natural water
Bacteria inactivation and natural organic matter oxidation in river water was simultaneously conducted via photo-Fenton reaction at "natural" pH (similar to 6.5) containing 0.6 mg L-1 of Fe3+ and 10 mg L-1 of H2O2. The experiments were carried out by using ...
2009Lanthanide chelates of (bis)-hydroxymethyl-substituted DTTA with potential application as contrast agents in magnetic resonance imaging
A novel bis-hydroxymethyl-substituted DTTA chelator N¢-Bz-C4,4¢-(CH2OH)2-DTTA (1) and its DTPA analogue C4,4¢-(CH2OH)2-DTPA (2) were synthesized and characterized. A variable-temperature 1H NMR spectroscopy study of the solution dynamics of their diamagnet ...
2009Elimination of Organic Micropollutants in a Municipal Wastewater Treatment Plant Upgraded with a Full-Scale Post-Ozonation Followed by Sand Filtration
Urs von Gunten, Juliane Hollender, Hansruedi Siegrist
The removal efficiency for 220 micropollutants was studied at the scale of a municipal wastewater treatment plant (WWTP) upgraded with post-ozonation followed by sand filtration. During post-ozonation, compounds with activated aromatic moieties, amino func ...
2009Equilibrium desorption isotherms of water, ethanol, ethyl acetate and toluene on a sodium smectite clay
John Christopher Plummer, Pascal Clausen
Desorption isotherms for water, ethanol, ethyl acetate and toluene from a sodium smectite clay have been determined by both dynamic vapor sorption (DVS) measurements and Knudsen thermogravimetry (KTGA), at the exception of toluene that was measured only by ...

Philippe Renaud, Thomas Michael Braschler, Ana Valero, Anja Kunze, Ludovica Colella, Joël Theytaz, Grazia Loche
Controlling alginate gel formation by diffusion of Ca ions through a filter barrier, a layer-by-layer deposition technique with resolution on the size scale of a single cell is presented. It gives the possibility of exposing cells under biocompatible condi ...
2009Characterization of different water pools in solid-state NMR protein samples
We observed and characterized two distinct signals originating from different pools of water protons in solid-state NMR protein samples, namely from crystal water which exchanges polarization with the protein (on the NMR timescale) and is located in the pr ...
SPRINGER2009Flow in a Pelton Turbine Bucket: Numerical and Experimental Investigations
François Avellan, Mohamed Farhat, Alexandre Perrig
The aim of the paper is to present the results of investigations conducted on the free surface flow in a Pelton turbine model bucket. Unsteady numerical simulations, based on the two-phase homogeneous model, are performed together with wall pressure measur ...
