Effect of spilling from adjacent orifices on the velocity field and pressures in front of needle stop-logs

Giovanni De Cesare, Azin Amini, Cédric Bron, Ivan Stojnic

In this study, the effect of spilling from neighboring sluice gates on stop-logs was experimentally investigated on a 1:65 physical scale model comprised of a double arch dam, a reservoir area, six spillway orifices and two stop-logs. Two types of measurem ...

Identification of above-zone pressure perturbations caused by leakage from those induced by deformation

Victor Vilarrasa Riano

Pressure changes in the above zone, i.e., the overlying aquifer of an injection zone separated by a sealing caprock, are usually attributed to leakage through wells. However, pressure changes can be induced geomechanically due to rock deformation without a ...

Carbon integration and transfer by the photosynthetic symbiotic dinoflagellates of the planktonic foraminifer Orbulina universa observed by TEM-nanoSIMS techniques

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

The planktonic foraminifera Orbulina universa is living in the photic zone of marine water columns and it possesses photosynthetic microalgae symbionts in its cytoplasm (dinoflagellates). The transfer of carbon compounds from the symbiotic microalgae to th ...

Assemblages and paleo-diet variability of subfossil Chironomidae (Diptera) from a deep lake (Lake Grand Maclu, France)

François Gillet

The heterogeneity of the subfossil chironomid deposition (in terms of assemblages and paleo-diet) has to be studied to assess the reliability of paleolimnological interpretations (i.e., spatial representativeness). We collected 31 cores in the deepest part ...

Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis

Andrea Rinaldo, Andrea Giometto, Amos Maritan, Florian Altermatt

Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...

3D modelling of dreissenid mussel impacts on phytoplankton in a large lake supports the nearshore shunt hypothesis and the importance of wind-driven hydrodynamics

Damien Bouffard

A three-dimensional hydrodynamic model (ELCOM) coupled with a biological model (CAEDYM) was calibrated with field data from Lake Simcoe (2008) and used to examine the expected impact of dreissenid mussels on the distribution of phytoplankton and nutrients, ...

Use of silicate minerals for pH control during reductive dechlorination of chloroethenes in batch cultures of different microbial consortia

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

In chloroethene-contaminated sites undergoing in situ bioremediation, groundwater acidification is a frequent problem in the source zone, and buffering strategies have to be implemented to maintain the pH in the neutral range. An alternative to conventiona ...

Bulk velocity measurements by video analysis of dye tracer in a macro-rough channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Steep mountain rivers have hydraulic and morphodynamic characteristics that hinder velocity measurements. The high spatial variability of hydraulic parameters, such as water depth (WD), river width and flow velocity, makes the choice of a representative cr ...

Optimizing Mix-zone Coverage in Pervasive Wireless Networks

Jean-Pierre Hubaux, Murtuza Jadliwala, Igor Bilogrevic

Location privacy is a major concern in pervasive networks where static device identifiers enable malicious eavesdroppers to continuously track users and their movements. In order to prevent such identifier-based tracking, devices could coordinate regular i ...

Catchment-scale herbicides transport: Theory and application

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

This paper proposes and tests a model which couples the description of hydrologic flow and transport of herbicides at catchment scales. The model accounts for streamflow components' age to characterize short and long term fluctuations of herbicide flux con ...
