Syntectonic fluid-flow along thrust faults: Example of the South-Pyrenean fold-and-thrust belt

21 mars 2014

During compressive events, deformation in sedimentary basins is mainly accommodated by thrust faulting and related fold growth. Thrust faults are generally rooted in the basement and may act as conduits or barriers for crustal fluid flow. Most of recent studies suggest that fluid flow through (...)

Polyphasic analysis of a middle ages coprolite microbiota, belgium.

11 mars 2014

Paleomicrobiological investigations of a 14(th)-century coprolite found inside a barrel in Namur, Belgium were done using microscopy, a culture-dependent approach and metagenomics. Results were confirmed by ad hoc PCR - sequencing. Investigations yielded evidence for flora from ancient (...)

Unprecedented changes in mollusc assemblages of the littoral zone in the two largest peri-Alpine lakes since the last 4500 years

27 février 2014

This paper presents changes in mollusc assemblages in the two largest peri-Alpine French lakes, i.e. Lakes Bourget and Annecy, in eastern France during the late Holocene. It is based on new mollusc data obtained in Lake Bourget (1) from three sediment cores spanning the late Holocene period and (...)

Hydrochemistry, a tool for understanding karst groundwater flows

26 février 2014

Karst is a highly heterogeneous medium (i.e. properties vary from one point to another one), and can be studied by variations of water chemical composition, which reflect in space and time differences in origin (runoff on impervious media, diffuse seepage, inflows from evaporites...) or (...)

hydrogeology and water balance in karst terrain

26 février 2014

Hydrogeology and water balance in karst terrain Jacques Mudry Chrono-Environnement, Besançon (France) 1 Introduction Karst is defined as "all superficial and underground landforms produced by dissolution of specific rocks, mainly limestone". At the same time, it is a morphological structure (...)

Application of isotopic tracers as a tool for understanding hydrodynamic behavior of the highly exploited Diass aquifer system (Senegal)

26 février 2014

The Diass horst aquifer system located 50 km east of Dakar (Senegal) is exploited in two main aquifers covered by a sandy superficial aquifer: the confined/unconfined Palaeocene karstic limestone and the confined Maastrichtian sandstone aquifer underneath. This system has experienced intensive (...)

Using the genetics of Echinococcus multilocularis to trace the history of expansion from an endemic area.

26 février 2014

: Alveolar echinococcosis, caused by the cestode Echinococcus multilocularis, is the most serious parasitic disease for humans in Europe, with a sylvatic life cycle generally between small rodents and red foxes. General expansion of the range of E. multilocularis has been observed across Europe (...)

Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options.

8 février 2014

OBJECTIVE: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and (...)

Depth-specific responses of a chironomid assemblage to contrasting anthropogenic pressures: a palaeolimnological perspective from the last 150 years

15 janvier 2014

1. The specific effects of three types of anthropogenic forcing (nutrient concentrations, climate change and fisheries management practices) on the benthic invertebrate community over the last 150 years in a re-oligotrophicated large, deep subalpine lake were investigated using chironomid (...)

Mid-crustal shear zone formation in granitic rocks: Constraints from quantitative textural and crystallographic preferred orientations analyses

14 janvier 2014

This paper presents quantitative microstructural and crystallographic preferred orientation (CPO) analyses of an Alpine amphibolite facies shear zone developed in the Fibbia metagranite (Gotthard massif, Central Alps). The weakly deformed metagranite and orthogneiss at the margins of the shear (...)

Influenza outbreaks management in a French psychiatric hospital from 2004 to 2012.

9 janvier 2014

OBJECTIVE: Influenza epidemics can have consequences in terms of morbidity and mortality for the patients. This work assesses influenza outbreaks in order to validate and optimize alert and control measures in a psychiatric hospital. METHOD: The prospective monitoring of influenza episodes was (...)

Introduction of a multiagent paradigm to optimise a case-based reasoning system designed to personalise three-dimensional numerical representations of human organs

5 janvier 2014

The Case-Based Reasoning (CBR) approach consists of retrieving solutions from similar past problems and adapting them to new problems. Interpolation tools can easily be used as adaptation tools in CBR-systems. The accuracies of interpolated results depend on the set of known solved problems (...)

Carbon sinks in small Sahelian lakes as an unexpected effect of land use changes since the 1960s (Saga Gorou and Dallol Bosso, SW Niger)

27 novembre 2013

For several decades, global change has resulted in an increase in runoff in the Sahelian belt, provoking major changes in the quality and quantity of sediments transported by drainage networks. One of the astonishing consequences is the establishment of numerous permanent lakes. The origins of (...)

Dispersal, landscape and travelling waves in cyclic vole populations.

23 novembre 2013

Travelling waves (TW) are among the most striking ecological phenomena emerging in oscillating populations. Despite much theory, understanding how real-world TW arise remains a challenge for ecology. Herein, we analyse 16-year time series of cyclic vole populations collected at 314 localities (...)

Association between Ambient Noise Exposure and School Performance of Children Living in An Urban Area: A Cross-Sectional Population-Based Study

23 novembre 2013

Most of the studies investigating the effects of the external noise on children's school performance have concerned pupils in schools exposed to high levels due to aircraft or freeway traffic noise. However, little is known about the consequences of the chronic ambient noise exposure at a level (...)

Case-Based Reasoning adaptation of numerical representations of human organs by interpolation

29 mai 2013

Case-Based Reasoning (CBR) and interpolation tools can provide solutions to unknown problems by adapting solutions from other problems already solved. We propose a generic approach using an interpolation tool during the CBR-adaptation phase. The application EquiVox, which attempts to design (...)
