Sharp transition in modes of dynamic crack propagation in dry-snow slab avalanche

Dry-snow slab avalanche release can be separated in four distinct phases : (i) failure initiation in a weak snow layer, (ii) onset, (iii) dynamics of crack propagation in the weak layer and eventually (iv)slab release. While a lot has been done to study th ...

Pioneer plant Phalaris arundinacea and earthworms promote initial soil structure formation despite strong alluvial dynamics in a semi-controlled field experiment

Claire Guenat, Pascal Turberg, Renée-Claire Le Bayon, Andreas Cedric Schomburg, Muhammad Riaz

Soil structure formation is among the most important processes in riverfloodplains which are strongly influ-enced by alluvial dynamics. In the context of river restoration projects, a better understanding of soil structureformation in habitats adjacent to ...

El sistema operacional MINERVE para la previsión de crecidas en el Cantón de Valais, Suiza

Javier García Hernández, Alain Tommy Foehn

In recent decades, the watershed of the Rhône River, upstream of Lake Geneva in Switzerland, has suffered three major floods that have caused damages for over 500 million dollars. This led to the third correction of the Rhône River, which aims to improve f ...

Monitoring of steel-lined pressure shafts considering water-hammer wave signals and fluid-structure interaction

Fadi Hachem

High head pressure tunnels and shafts of hydropower plants with low rock overburden have to be steel-lined. Since the water can reach in an uncontrolled way the rock surface in case of failure of these water-conveying systems, high damages due to landslide ...

Climate Change and Tourism in Switzerland: a Survey on Impacts, Vulnerability and Possible Adaptation Measures

Cecilia Matasci, Juan Carlos Altamirano Cabrera

The tourism industry is particularly affected by climate change, being very climate- and weather- dependent. Moreover, particularly in the Alpine region, it is specially exposed to natural hazards. Nonetheless, this industry is an important pillar of the S ...

Climate Change and Tourism in Switzerland : Impacts, Vulnerability and Possible Adaptation Measures

Cecilia Matasci

Climate change is a global phenomenon, but its effects occur on a local scale. An example is provided by tourism. Tourism is closely interlinked with climate change both as culprit and as victim. On the one hand, it is responsible for a large portion of GH ...

Suppression of leakage currents in GaN-based LEDs induced by reactive-ion etching damages

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Julien Dorsaz, Antonino Francesco Castiglia, Mauro Mosca

Forward and reverse leakage currents in GaN/InGaN multi-quantum well light-emitting diodes (LEDs) are caused by reactive-ion etching (RIE) damages during device patterning. A method to recover the damaged surfaces, based on a chemical etch in KOH: ethylene ...

Assessment of existing steel structures. A guideline for estimation of the remaining fatigue life

Alain Nussbaumer

In many countries and regions, traffic infrastructure projects suffer from low funding. The budget is tight for new infrastructure building and, thus, the importance of inspection, maintenance and assessment of the existing traffic infrastructure increases ...

Earthquake Induced Damage Estimation in Steel Buildings

Gustavo Cortes

This work presents a method for estimating the expected damage caused by an earthquake on steel buildings in Puerto Rico. Since Puerto Rico is located between a series of tectonic faults, buildings could suffer the damages caused by a major earthquake. The ...

Antioxidant Sensors Based on DNA-Modified Electrodes

Hubert Girault, Christophe Roussel

TiO2/ITO modified electrodes were developed to quantitatively photooxidize adsorbed ds-DNA and to study the effect of antioxidants as ds-DNA protecting agents. TiO2 films are used for efficient ds-DNA immobilization, for ds- DNA oxidation through photogene ...
