Indication of spatially random infection of chlamydia-like organisms in Bufo bufo tadpoles from ponds located in the Geneva metropolitan area

Stéphane Joost, Oliver Michele Selmoni, Séverine Vuilleumier Varisco, Estelle Rochat, Elia Vajana, Ivo Widmer

Occurrence of bacteria belonging to the order Chlamydiales was investigated for the first time in common toad (Bufo bufo) tadpole populations collected from 41 ponds in the Geneva metropolitan area, Switzerland. A Chlamydiales-specific Real-Time PCR was us ...

FROG: rapid prototyping of collaborative learning scenarios

Pierre Dillenbourg, Louis Pierre Faucon, Stian Haklev, Thanasis Hadzilacos

We describe FROG, an integrated environment for authoring and running collaborative learning scenarios, called Orchestration Graphs. We describe the pedagogical background and the technical architecture, and present a case study of a teacher using FROG to ...

Reindustrializing Europe

Roberto Sega, Ianira Vassallo

“For a European Industrial Renaissance” it’s the title of the European Commission Communication in January 2014 which promotes the reintroduction of production of goods and services in Europe and wants to implement a solid industry base through specific po ...

Performance analysis of jump-gliding locomotion for miniature robotics

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey

Recent work suggests that jumping locomotion in combination with a gliding phase can be used as an effective mobility principle in robotics. Compared to pure jumping without a gliding phase, the potential benefits of hybrid jump-gliding locomotion includes ...

Mixtures of Chemical Pollutants at European Legislation Safety Concentrations: How Safe Are They?

Kristin Schirmer

The risk posed by complex chemical mixtures in the environment to wildlife and humans is increasingly debated, but has been rarely tested under environmentally relevant scenarios. To address this issue, two mixtures of 14 or 19 substances of concern (pesti ...

Fluidized States of Vibrated Granular Media Studied by Mechanical Spectroscopy

Daniele Mari, Gérard Gremaud, Alessandro Luigi Sellerio

We investigate the jamming transition observed in vibrated granular systems composed of millimeter size glass beads. When a granular system is submitted to vibrations with decreasing intensity, it evolves in a way similar to glass-forming liquids: from a l ...

Glass transition associated with the jamming of vibrated granular matter

Daniele Mari, Gérard Gremaud, Alessandro Luigi Sellerio

We investigate a vibrated granular system composed of millimeter-size glass beads. When the system is submitted to a perturbation with decreasing intensity, below the fluidization limit, it evolves in a way similar to glass-forming liquids until it reaches ...

Brain energy metabolism and neurotransmission at near-freezing temperatures: In vivo 1H MRS study of a hibernating mammal

Rolf Gruetter

The brain of a hibernating mammal withstands physiological extremes that would result in cerebral damage and death in a non-hibernating species such as humans. To examine the possibility that this neuroprotection results from alterations in cerebral metabo ...

Amphibian conservation in human shaped environments

Flavio Zanini

Global biodiversity is experiencing a worrying decline. Habitats destruction, associated to their degradation and fragmentation are among the greatest causes. Amphibians are particularly interesting because they are more threatened and decline more rapidly ...

Fluid and glassy phases of vibrated granular matter studied with a torsion oscillator

Patrick Mayor

Granular matter submitted to external perturbations exhibits various behaviors depending on the vibration intensity: when strongly vibrated, the granular system has a fluid aspect, whereas under low intensity perturbations, it is in a quasi-solid phase. In ...
