This paper presents results of the last five years of landslide detection and landslide susceptibility mapping in the Central and Southern Tien Shan. Landslide inventories have been compiled for areas of major interest in the Kyrgyz Republic. For those areas, landslides were first mapped manually using KFA satellite images and aerial photographs. Recently, a landslide detection method has been developed in order to map landslides automatically. This method is based on a neural network scheme applied to detect particular slope failure features from remote sensing data. Multi-spectral and/or panchromatic ASTER and SPOT images as well as digital elevation models (DEMs) are used as inputs. This automatic method is designed to map medium-size mass movements (105-107 m3). This approach supplements the manual mapping of large slope failures and helps to complete the inventory of mass movements and related landslide susceptibility/hazard maps for large areas within the Tien Shan. Size-frequency analyses have been applied to the two existing regional landslide inventories. These size-frequency analyses revealed the incompleteness of the respective inventories (in the low-size domain) as well as regional and local differences due to natural and anthropogenic influences. To be able to perform reliable susceptibility and size-frequency analyses, the completed inventories need to be verified. At present, we perform local verification by manual mapping and control, but automatic verification methods are being developed. They will also allow us to determine the level of uncertainties. Ongoing research is focused on the propagation of uncertainties throughout the chain of processing. [less ▲]

This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments. This constitutive model constitutes an effective tool for modelling the thermo-hydro-mechanical (THM) behaviour of geomaterials involved in the confinement of nuclear waste disposal. [less ▲]

Un modèle constitutif thermo-hydro-mécanique dédié aux sols fins a été développé afin de prédire le comportement des géomatériaux intervenant dans la problématique du confinement des déchets nucléaires en couche géologique profonde. Ce modèle considère l’aspect couplé des processus thermique, hydrique et mécanique. Les équations constitutives sont présentées. L’implémentation de cette loi de comportement dans deux logiciels d’éléments finis a permis une étude rigoureuse de plusieurs scénarios rencontrés dans les sols entourant les futurs déchets radioactifs. Les enseignements de chacune de ces études ainsi que l’apport du modèle utilisé sont présentés. [less ▲]

Fish models are increasingly being used for hearing research investigations. Aminoglycoside antibiotics that are used for damaging the inner ear hair cells can have systemic side effects leading to death of study animals. This study aimed to compare two methods: (i) systemic (intravenous) and (ii) local (intrasaccular) gentamicin administration for induction of inner ear hair cell damage in the Atlantic cod, Gadus morhua (L.). Hair cell damage was assessed using scanning electron microscopy; hair cell density, prevalence of immature hair cells and kinocilia length were measured. Gentamicin-treated fish were compared with control and sham fish. Intravenous gentamicin led to dose-dependent mortality caused by nephrotoxicity. The only visible effect after treatment was more immature hair cells and shorter kinocilia, the effect on hair cell density was equivocal. Following intrasaccular gentamicin treatment, fish mortality was negligible, and hair cells were damaged regardless of dose. Here, we observed decreased hair cell density, high prevalence of immature hair cells, and significantly shortened kinocilia. Conclusion: intrasaccular injection is preferable to intravenous injection of gentamicin for the study of ototoxicity in the Atlantic cod. [less ▲]

The effect of chronic exposure to a low concentration (0.5 microg l(-1)) of cadmium ions was investigated on escape behaviour of sea bass, Dicentrarchus labrax, using video analysis. Observations were also performed on the microanatomy of lateral system neuromasts. When fish were exposed for 4h per day over 8 days to the cadmium ions, most of both types of neuromasts observed remained intact. However, some of them presented damaged sensory maculae. Whereas before cadmium exposure, fish responded positively to nearly all the lateral system stimulations, after exposure they decreased by about 10% their positive responses to stimulations. From the 15th day after the beginning of cadmium exposure, neuromasts presented progressively less damage, cadmium accumulation in gills and scales decreased significantly and fish escape behaviour had recovered. This study presents a new concept in ecotoxicology: using behavioural change to reveal the effects of pollution levels, scarcely detectable by currently used techniques (physiological responses).

Off the coast of Saintes-Marie-de-la-Mer, in the confluence of one of the ancient branches of the Rhone, eleven wrecks transporting mainly iron have been discovered. Dated from the turn of our era (the end of the first century BC - first century AD), each one delivers between 20 and 150 tons of iron which break down into eight standardized semi-finished products (types and subtypes included), sometimes stamped. We propose to specify these typological and epigraphic characteristics through archeometric studies undertaken on around fifty of these bars. Metallographic and chemical characteristics are then established in each unit. They make it possible to understand the technical reality of a complex typology and to refine our knowledge of the ferrous production networks in the Roman Mediterranean world. [less ▲]

Four brachiopod species from the upper Givetian of Ferques are described of which two are new: Cupularostrum minimum n. sp. (Rhynchonellida) and Cleiothyridina blacourti n. sp. (Athyridida). The third, which is assigned to Stringocephalus aff. fontanus Veevers, 1959, corresponds after revision to S. sp. (in Brice & Loones 2002) pro parte. The fourth is Stringodiscus giganteus (Sowerby, 1840) which is recorded for the first time in France. Material originates mainly from the Couderousse Member of the Blacourt Formation, dated by conodonts from the “Middle-Upper varcus Zone”, but exclusively for S. aff. fontanus and St. giganteus. Some rare specimens of C. minimum and Cl. blacourti have been collected in the lower part of the Bastien Member, upper part of the Blacourt Formation. Cl. blacourti is very common in the upper Givetian of Ferques, so the genus Cleiothyridina appears as soon as the upper Givetian as in Spain and not in the Famennian as it is reported in the “Treatise revised” (Alvarez & Rong, 2002).
