Article Reference C source code Exchange processes and nitrogen cycling on the shelf and continental slope of the Black Sea basin.
A 3D coupled biogeochemical-hydrodynamical model has been applied to the Black Sea to simulate nitrogen cycling and to estimate the exchange of biogeochemical components at the shelf break and between the continental slope and the deep sea. It was found that biological processes on the northwestern shelf are in approximate balance. Primary production is fueled by river discharge, nitrate input from the open sea at the shelf break, and in situ remineralization. The input of nitrate from the open sea is roughly equivalent to the river nitrate discharge but is half the nitrate export from the shelf toward the open sea. Also, the Black Sea shelf acts throughout the year as a nitrate source for the open sea. The amount of shelf production not remineralized in the euphotic layer is 22.2% and is exported to lower layers (20%) or offshore (2.2%). We estimate that the export of carbon from the shelf to the interior of the basin represents 2.5% of the new production of the open sea. The upper slope adjoining the northwestern shelf is the site of downwelling events responsible for the downward transport to the intermediate layer of the continental slope of biogeochemical components exported from the shelf in the upper layer. The shelf has been found to be an efficient trap for the refractory material discharged by the Danube.

Article Reference Experiences with low and high cost 3D surface scanner.
The increasing importance of virtual techniques in archaeology and anthropology puts the question of adequate hardware and software applications for a digitalization of collections for museums and institutions into the focus. Especially the market for mobile 3D scanning developed rapidly during the last years and provides a range of different models suitable for scientific purposes today. As the requirements for archaeological and anthropological applications are very high and differentiated - due to the, in some cases very complex surface morphologies of the objects and the different textures from shiny obsidian to porous bone - the decision for a scanner model is often complicated. The Neanderthal Museum and the Royal Belgian Institute of Sciences have been testing six different surface scanner from four companies during the last months concerning their suitability for archaeological and anthropological objects. Quality of the 3D models was rated by the visibility and exactness of standard attributes used for classification of the object type in archaeology or anthropology. Results are presented here. Generally, all types of archaeological and anthropological objects can be digitalized with surface scanner. If a high end or a low budget model should be used depends on the texture of the object and the intended purpose.

Article Reference Experimental exposure to cadmium affects metallothionein-like protein levels but not survival and growth in wolf spiders from polluted and reference populations
Both local adaptation and acclimation in tolerance mechanisms may allow populations to persist under metal pollution. However, both mechanisms are presumed to incur (energetic) costs and to trade-off with other life-history traits. To test this hypothesis, we exposed Pardosa saltans (Lycosidae) spiderlings originating from metal-polluted and unpolluted sites to a controlled cadmium (Cd) treatment, and compared contents of metal-binding metallothionein-like proteins (MTLPs), internal metal concentrations, and individual survival and growth rates with a reference treatment. While increased MTLP concentrations in offspring originating from both polluted and unpolluted populations upon exposure indicates a plastic tolerance mechanism, survival and growth rates remain largely unaffected, independent of the population of origin. However, MTLP and Cd concentrations were not significantly correlated. We suggest that MTLP production may be an important mechanism enabling P. saltans populations to persist in ecosystems polluted with heavy metals above a certain level. (C) 2010 Elsevier Ltd.

Phdthesis Reference Exploitation des ressources végétales et pratiques alimentaires dans le nord de la France entre les Xe et XIIe siècles : études carpologiques de la motte castrale de Boves (Amiens, Somme) et des sites environnants
Les analyses carpologiques d’un ensemble de six sites situés, pour la plupart, en région Picardie, nous permettent d’appréhender l’exploitation des ressources végétales et les pratiques alimentaires de la France septentrionale entre le Xe et le XIIe siècle. En dépit de biais taphonomiques importants, dus à un matériel conservé par minéralisation et carbonisation, très érodé, une grande variété d’espèces a pu être identifiée. Les assemblages carpologiques montrent que les Blés nus et le Seigle sont les céréales dominantes. De nombreuses légumineuses sont mentionnées mais le Pois et la Vesce cultivée sont les plus abondants, accompagnés de la Féverole. La grande quantité des restes de fruitiers retrouvés, souligne une fructiculture en plein essor de telle sorte que la question sur la mise en culture des « petits fruits des bois » ou l’exploitation des milieux forestiers pour ces denrées est posée. La Vigne semble très bien implantée dans la région. Des restes récurrents de figue nous questionnent sur le statut importé de méditerranée des fruits ou cultivé localement de l’arbre. Sur les six sites étudiés, quatre sont de milieux aisés. Les indices carpologiques caractéristiques du niveau socio-économique d’un site sont principalement discutés à la lumière des pratiques alimentaires. Enfin, le processus de minéralisation est abordé et son induction par des pratiques d’assainissement au sein des latrines/fosses dépotoirs est suggérée. Archaeobotanical investigations of six medieval sites in Northern France (Picardy) have provided charred and mineralised plant remains (seeds and fruits). Despite some taphonomical constraints of the different preservation of these plant assemblages, archaeobotanical analysis revealed valuable information on the diet, the agriculture and the horticultural production of the medieval population in Northern France between 10th and 12th Century AD. The archaeobotanical results were influenced by the different types of features from which macro-remains were retrieved and by the reliability of the samples. The main crops plants were naked wheat and rye. The pulses, pea and common vetch are the major common crops with field bean. Fruits are very abundant and attest a wide-spread fructiculture. The number of recorded remains from the “wild forest fruits” raises the question of their probable cultivation or of their exploitation in forest. The Vineyard seems very well implanted in the region. Recurring macrorests of fig question about the status imported of Mediterranean fruits or cultivated locally by the tree. The social context of 4 archaeological sites is high. The potential of archaeobotanical data helping to identify social differences by defining archaeobotanical indicators of social level is to be discussed from the food practices and the diet. Finally, the mineralization process is approached and its induction by practices of purification within latrines / pits garbage dumps is suggested.
