Global emergent responses of stream microbial metabolism to glacier shrinkage
Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Nicola Deluigi, Tyler Joe Kohler, Michail Styllas
Most cryospheric ecosystems are energy limited. How their energetics will respond to climate change remains largely unknown. This is particularly true for glacier-fed streams, which interface with the cryosphere and initiate some of Earth's largest river s ...
Berlin2024A moored profiling platform to study turbulent mixing in density currents in a large lake
David Andrew Barry, Ulrich Lemmin, François Mettra, Rafael Sebastian Reiss, Valentin Kindschi, Benjamin Daniel Graf
During calm cooling periods, differential cooling can induce winter cascading which is an important process for littoral-pelagic exchange and deep water renewal in large, deep lakes (Fer et al., 2001; Peeters et al., 2003). Generated in the shallow near-sh ...
2023Fully rehabilitation: integrating a small hydro cascade into a water supply system
A rehabilitation scheme at the more than 100 year-old Fully hydro scheme, where the penstock had shown signs of ageing, has involved converting the original single power station into a cascade of three plants, which have been integrated in a municipal wate ...
2016Ligand-Centred Fluorescence and Electronic Relaxation Cascade at Vibrational Time Scales in Transition-Metal Complexes
Majed Chergui, Enrico Pomarico, Mahsa Silatani
Using femtosecond-resolved photoluminescence up-conversion, we report the observation of the fluorescence of the high-lying ligand-centered (LC) electronic state upon 266 nm excitation of an iridium complex, Ir(ppy)(3), with a lifetime of 70 +/- 10 fs. It ...
Amer Chemical Soc2015Snowpack regimes of the Western United States
Snow accumulation and melt patterns play a significant role in the water, energy, carbon, and nutrient cycles in the montane environments of the Western United States. Recent studies have illustrated that changes in the snow/rainfall apportionments and sno ...
American Geophysical Union2014IR-UWB transmitter
Jean-Yves Le Boudec, Catherine Dehollain, Edmund James Colli-Vignarelli
A generator of very short pulses where a cascade of inverters of arbitrary length characterized in that said inverters are adapted to produce pulses on their power supply line instead of their usual output. ...
2012Fluid-Structure Coupling Effects on the Dynamic Response of Pump-Turbine Guide Vanes
Hydraulic pump-turbines are subject to a high periodic excitation due to the Rotor-Stator Interaction, RSI. Basically, the RSI is caused by the impeller blade passage in the wake of the guide vanes in generating mode, or upstream from the guide vanes in pu ...
EPFL2012Are there "dragon-kings" events (i.e. genuine outliers) among extreme avalanches?
Predicting the occurrence and spatial extent of extreme avalanches is a longstanding issue. Using field data pooled from various sites within the same mountain range, authors showed that the avalanche size distribution can be described using either an extr ...
