Transmission dynamics of Norovirus GII and Enterovirus in Switzerland during the COVID-19 pandemic (2021-2022) as evidenced in wastewater

Tamar Kohn, Timothy R. Julian, Htet Kyi Wynn, Shotaro Torii, Charles Zeng Gan

Noroviruses and enteroviruses are major causes of endemic gastrointestinal disease associated with substantial disease burden. However, viral gastroenteritis is often diagnosed based on symptoms, with etiology infrequently tested or reported, so little inf ...

Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria

Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler, Htet Kyi Wynn, Céline Terrettaz, Laura José Costa Henriques

Aerosol transmission remains a major challenge for control of respiratory viruses, particularly those causing recurrent epidemics, like influenza A virus (IAV). These viruses are rarely expelled alone, but instead are embedded in a consortium of microorgan ...

Rapid changes in river plume dynamics caused by advected wind-driven coastal upwelling as observed in Lake Geneva

David Andrew Barry, Ulrich Lemmin, Htet Kyi Wynn, Frédéric Charles Soulignac, Seyed Mahmood Hamze Ziabari, Benjamin Daniel Graf

Based on field investigations carried out in Lake Geneva during summer stratification in 2019, this study documents, for the first time, the rapid change of negatively buoyant river inflow dynamics caused by the passing of a coastal upwelling. Under calm c ...

Substance flow analysis as a tool for mitigating the impact of pharmaceuticals on the aquatic system

Luca Rossi, Jonas Margot, Sylvain Coutu, Htet Kyi Wynn

Pharmaceuticals constitute an important environmental issue for receiving waters. A holistic approach, taking into consideration the sources of these compounds (hospitals, domestic use), discharges (wastewater effluent, combined sewer overflows) and relate ...

Identifying and quantifying unexpected deep zooplankton diel vertical migration in a large deep lake

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

Diel Vertical Migration (DVM), a widespread zooplankton behavior in freshwater and marine systems, affects ecological interactions and biogeochemical cycles. In lakes, DVM has mainly been studied in the upper 50 m of the water column. However, based on aco ...

A low-cost, autonomous mobile platform for limnological investigations, supported by high-resolution mesoscale airborne imagery

David Andrew Barry, Ulrich Lemmin, Anton Ivanov, Htet Kyi Wynn, Stepan Tulyakov, Abolfazl Irani Rahaghi, Ludovic Zulliger, Jean-Luc Liardon, Philippe Olivier Paccaud, Beat Marcel Geissmann

Two complementary measurement systems – built upon an autonomous floating craft and a tethered balloon – for lake research and monitoring are presented. The autonomous vehicle was assembled on a catamaran for stability, and is capable of handling a variety ...

Tracing Unconfined Nearfield Spreading of a River Plume Interflow in a Large Lake (Lake Geneva): Hydrodynamics, Suspended Particulate Matter, and Associated Fluxes

David Andrew Barry, Ulrich Lemmin, Htet Kyi Wynn, Frédéric Charles Soulignac, Violaine Florette Piton, Benjamin Daniel Graf

River inflows have a major influence on lake water quality due to their input of sediments, nutrients and contaminants. After leaving the river channel, river waters form a plume and interact with ambient lake waters. Strong hydrodynamic changes take place ...

From Particles to Flocs: Revealing Where Flocculation Occurs in the Nearfield of a Negatively-Buoyant River Plume in a Large Lake (Lake Geneva)

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

The dynamics of sediments entering lakes in river plumes is virtually unknown. This field study provides unprecedented evidence of the initiation and evolution of suspended sediment flocculation in the nearfield of the negatively-buoyant Rh & ocirc;ne Rive ...

Temporal dynamics of antibiotics in wastewater treatment plant influent

David Andrew Barry, Luca Rossi, Sylvain Coutu, Htet Kyi Wynn, Vera Wyrsch

A yearlong field experimental campaign was conducted to reveal time scales over which antibiotic fluxes vary in the influent of a wastewater treatment plant (WTP). In particular, sampling was carried out to ascertain the amplitudes of monthly, daily and ho ...
