Selective elimination of enterovirus genotypes by activated sludge and chlorination

Enteroviruses, which are commonly circulating viruses shed in the stool, are released into the sewage system and only partially removed or inactivated, resulting in the discharge of infectious enteroviruses into the environment. Activated sludge and chlori ...

Colloidal transport and deposition through dense vegetation

David Andrew Barry, Li Chen, Congrong Yu

The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...

ACACIA: a new method to produce on-the-fly merger trees in the RAMSES code

Mladen Ivkovic

The implementation of ACACIA, a new algorithm to generate dark matter halo merger trees with the Adaptive Mesh Refinement code RAMSES, is presented. The algorithm is fully parallel and based on the Message Passing Interface. As opposed to most available me ...

Suspended sediments in Lake Geneva: Observations, settling behaviour and mechanisms in the Rhône River plume

David Andrew Barry, Ulrich Lemmin, Htet Kyi Wynn, Violaine Florette Piton, Valentin Kindschi

In estuaries and marine environments, primary particles are frequently transported as large flocculated particles. This study provides, for the first time, evidence of in situ flocculation in Lake Geneva, a glacier-fed freshwater lake on the Swiss/French b ...

Nano-sized iron oxides supported on polyester textile to remove fluoroquinolones in hospital wastewater

Sami Rtimi

In this study, we examined the removal kinetics of two fluoroquinolones (FQs), flumequine (FLU) and ciprofloxacin (CIP), in synthetic wastewater (SWW) and real hospital wastewater (RHW) using FeOx thin films, peroxymonosulfate (PMS) and visible light. Nano ...

Self-Propulsion of Active Colloids via Ion Release: Theory and Experiments

Ignacio Pagonabarraga Mora, Samuel Sanchez

We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical phoretic models. This leads to a numbe ...

New approach for time-resolved and dynamic investigations on nanoparticles agglomeration

Francesco Stellacci, Antonia Neels, Alex Dommann, Urszula Beata Cendrowska, Claudio Toncelli

Nanoparticle (NP) colloidal stability plays a crucial role in biomedical application not only for human and environmental safety but also for NP efficiency and functionality. NP agglomeration is considered as a possible process in monodispersed NP colloida ...

Tissue Factor-Independent Coagulation Correlates with Clinical Phenotype in Factor XI Deficiency and Replacement Therapy

Christian Heinis, Vanessa Carle, Alessandro Aliotta

Background In factor XI (FXI) deficiency, bleeding cannot be predicted by routine analyses. Since FXI is involved in tissue factor (TF)-independent propagation loop of coagulation, we hypothesized that investigating the spatiotemporal separated phases of c ...

The effect of different organic substrates on the microbial communities of aerobic granular wastewater treatment sludge

Aline Sondra Adler

Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conven- tional activated sludge system, allowing space and energy savings. This process is particularly suited for biological phosphorus removal, avoiding use of coagulant ...

Interplay of hyporheic exchange and fine particle deposition in a riverbed

David Andrew Barry, Pei Zhang

Hyporheic flow transports fine particles into the riverbed, which can lead to clogging of the bed and in turn affect hyporheic flow and exchange processes. Field measurements and numerical simulations show the formation of a low-permeability layer (LPL) ne ...
