Overcoming challenges in the classification of deep geothermal potential [PDF]

open access: yes, 2015
The geothermal community lacks a universal definition of deep geothermal systems. A minimum depth of 400 m is often assumed, with a further sub-classification into middle-deep geothermal systems for reservoirs found between 400 and 1000 m.

Revisiting the EU's Democratic Deficit: Archival Insights From Maximalist Federalists

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This article explores the history of democratic problematisation of European integration, rather than taking part in the normative debate on the European Union's democratic legitimacy deficit that emerged in the 1990s. We focus on the narratives of non‐institutional actors who have considered that European integration should be a democratic ...

Changements à long terme des paysages forestiers dans cinq parcs nationaux métropolitains et le futur parc national des forêts de Champagne et Bourgogne

open access: yesRevue Forestière Française, 2017
Les parcs nationaux métropolitains, qui ont connu une forte progression de leur surface forestière depuis le milieu du XIXe siècle, s’intéressent depuis plusieurs années aux forêts anciennes.

Forming European Political Awareness and Facilitating Civic Engagement? Mainstream Europarties in Social Media

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This study investigates how mainstream Europarties utilise social media to communicate with the public. According to EU law, Europarties are expected to strengthen the EU's legitimacy, mainly by fostering European political awareness and facilitating civic engagement.

Impact of forest management regimes on ligneous regeneration in the Sudanian savanna of Burkina Faso [PDF]

open access: yes, 2007
Annual early fire, selective tree cutting and grazing exclusion are currently used to manage the State forests of the Sudanian savanna of Burkina Faso, West Africa. Such prescriptions, however, are not based on experimental evidence.

SiO excitation from dense shocks in the earliest stages of massive star formation

open access: yes, 2014
Molecular outflows are a direct consequence of accretion, and therefore they represent one of the best tracers of accretion processes in the still poorly understood early phases of high-mass star formation.

A single nucleotide polymorphism genotyping panel for efficient genetic stock identification of the Teno river Atlantic salmon (Salmo salar) population complex

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new single nucleotide polymorphism (SNP) panel for genetic stock identification in the Teno river Atlantic salmon, Salmo salar L., fishery was developed, with a view to improving on an existing microsatellite panel. Twenty‐two genetically differentiated reporting units were proposed based on population genetic analyses of 1212 individuals ...

The limited contribution of large trees to biomass dynamics in an old-growth tropical forest [PDF]

open access: yes, 2018
Although the importance of large trees regarding biodiversity and carbon stock in old-growth forests is undeniable, their annual contribution to biomass dynamics and carbon uptake remains poorly studied at the stand level.

Evolution and excitation conditions of outflows in high-mass star-forming regions [PDF]

open access: yes, 2013
Theoretical models suggest that massive stars form via disk-mediated accretion, with bipolar outflows playing a fundamental role. A recent study toward massive molecular outflows has revealed a decrease of the SiO line intensity as the object evolves ...
