Trois tudes de zones ont t conduites en 1997/1998 dans le bassin de Marennes-Olron (Charente-Maritime). Deux concernaient la contamination des coquillages fouisseurs de la Seudre et du banc de Ronce-Perquis. La troisime concernait la contamination des coquillages filtreurs des bouchots moules des Saumonards (Ile d'Olron). Ces tudes avaient pour objet d'valuer les niveaux de contamination microbiologique et chimique de ces zones de production de coquillages afin que l'Administration puisse en effectuer le classement sanitaire conformment l'arrt du 21 juillet 1995. La Seudre, l'aval de la rivire, a montr, pour les fouisseurs, une qualit microbiologique de catgorie B et une qualit microbiologique de catgorie C pour la partie amont. De son ct, le Banc de Ronce-Perquis a prsent, pour les fouisseurs, une qualit microbiologique de catgorie B. Enfin, la catgorie microbiologique des moules des bouchots des Saumonards est de type A. Le suivi du mercure total, du cadmium et du plomb dans la chair des coquillages a mis en vidence des teneurs infrieures aux valeurs seuil.

The quality of fish cultured using recycling units may differ from that of fish from outdoor farming units due to a range of deviating environmental determinants. This applies not only to flesh quality but also to morphological (processing) traits. This study evaluates processing yields of sibling fish cultured in two different farming units: (i) an outdoor pond aquaculture system with a flow-through regime (24.6 0.2C), and (ii) indoor tanks using a recirculation aquaculture system (RAS; 26.0 1.0C). Clear differences were observed in the most important processing traits, i.e. skinned trunk and fillet yields, which were both significantly higher (P < 0.01) in RAS fish due to significantly smaller (P < 0.05) head weight in fish of the flow-through system. Skin represented a significantly higher (P < 0.01) proportion of total weight in both RAS males and females. The most obvious difference was in the deposited fat weight, which was significantly higher (P < 0.01) in RAS fish. Visceral fat deposits were significantly higher (P < 0.01) in females and ventral and dorsal fat deposits higher (P > 0.05) in males.

A locational duality in port-related distribution activities is emerging. In some regions, distribution activities have moved from ports to inland locations, driven in part by push factors such as port congestion and scarcity of land for container handling activities, or by pull factors such as the growth of intermodal corridors, the influence of inland terminals and the changing economic geography in the hinterland. In other regions, ports retain their traditional role as centres of distribution and warehousing activity. More recently, the focus on port-centric logistics is indicative that some regions are refocusing on ports as potential locations for large distribution centres. The result has been a growing competition, but also complementarity, between ports and inland locations concerning the location of distribution activities, driven not only by market forces but also by institutional settings and the governance relations between the actors involved. This report provides an overview of regional differences across the world in order to develop a framework identifying for which type of distribution activities ports are suitable locations and which activities are best suited to the hinterland, taking into account geographical, economic and logistics settings. Empirical evidence is derived from a variety of regions in Europe, North America, South America, Southern Africa and Asia.

En este artculo se analizan representaciones sobre lo indgena manifiestas en un sector de la poblacin no indgena de Colombia, donde el chamanismo es un tema recurrente y donde las culturas indgenas son representadas como poseedoras de una sabidura espiritual, alternativa y benfica para la sociedad occidental. El anlisis de este tipo de ideas permite advertir similitudes con los discursos utilizados en diferentes latitudes para representar otras alteridades tnicas, lo cual no se debe a semejanzas objetivas entre los grupos tnicos, sino a similitudes socioculturales existentes entre las personas que se representan as lo tnico. Los resultados llevan a concluir que este indigenismo es la manifestacin local de una ideologa globalizada, centrada en los ideales y necesidades del yo moderno.

L'acclration des changements dans tous les domaines, qu'il s'agisse d'environnement, de technologies ou de la vie des socits humaines, est une donne majeure de notre temps. Jusqu'au XIXe sicle, les hommes gardaient une relative matrise des rvolutions, qu'elles soient techniques (la vapeur, l'lectricit, l'atome, ... ) ou sociales (la dmocratie, le communisme, etc). A la fin du XXe sicle, la complexit des socits humaines, le foisonnement des dcouvertes scientifiques rapidement exploites par l'industrie des fins conomiques et l'interdpendance croissante de toutes les activits dans des cosystmes fragiliss ont conduit les communauts humaines davantage subir les rvolutions: mondialisation d'une conomie de plus en plus immatrielle, explosion de l'informatique dans tous les secteurs, volution du climat, bouleversement des modes de vie et de la vie mme (actions sur les gnomes animaux, voire humains) ... Aussi, cette acclration des changements rend d'autant plus indispensable une capacit d'anticiper les tendances et les enjeux qui dterminent l'avenir afin de disposer d'une libert de rflexion et d'action indpendante de la stricte contrainte des vnements.

The main idea I would like to develop and assess in this paper was upheld and defended by Paul Ricoeur in his famous dictum that To say self is not to say I, and its corollary that the shortest route from self to self is through the other. That there is an implicit dialectic is underlined in another short passage taken from Ricoeurs book Oneself as Another:

Il sagit ici dexplorer le plaisir pris la lecture des romans policiers, lecture qui implique la participation du lecteur des reprsentations violentes et cruelles. Dans son rcit autobiographique Les Mots, Jean-Paul Sartre dclare en conclusion dun passage consacr ce quil appelle les vraies lectures de son enfance ces lectures lui sont donnes par les livres daventures et les magazines pour enfants, il les oppose aux lectures savantes : Cette double vie na jamais cess: aujourdhui encore, je lis plus volontiers les Srie Noire que Wittgenstein.

Interactions between photosynthetic and non-photosynthetic microorganisms play an essential role in natural aquatic environments and the contribution of bacteria and microalgae to the nitrogen cycle can lead to both competitive and mutualistic relationships. Nitrogen is considered to be, with phosphorus and iron, one of the main limiting nutrients for primary production in the oceans and its availability experiences large temporal and geographical variations. For these reasons, it is important to understand how competitive and mutualistic interactions between photosynthetic and heterotrophic microorganisms are impacted by nitrogen limitation. In a previous study performed in batch cultures, the addition of a selected bacterial strain of Alteromonas sp. resulted in a final biomass increase in the green alga Dunaliella sp. as a result of higher nitrogen incorporation into the algal cells. The present work focuses on testing the potential of the same microalgaebacteria association and nitrogen interactions in chemostats limited by nitrogen. Axenic and mixed cultures were compared at two dilution rates to evaluate the impact of nitrogen limitation on interactions. The addition of bacteria resulted in increased cell size in the microalgae, as well as decreased carbon incorporation, which was exacerbated by high nitrogen limitation. Biochemical analyses for the different components including microalgae, bacteria, non-living particulate matter, and dissolved organic matter, suggested that bacteria uptake carbon from carbon-rich particulate matter released by microalgae. Dissolved organic nitrogen released by microalgae was apparently not taken up by bacteria, which casts doubt on the remineralization of dissolved organic nitrogen by Alteromonas sp. in chemostats. Dunaliella sp. obtained ammonium-nitrogen more efficiently under lower nitrogen limitation. Overall, we revealed competition between microalgae and bacteria for ammonium when this was in continuous but limited supply. Competition for mineral nitrogen increased with nitrogen limitation. From our study we suggest that competitive or mutualistic relationships between microalgae and bacteria largely depend on the ecophysiological status of the two microorganisms. The outcome of microalgaebacteria interactions in natural and artificial ecosystems largely depends on environmental factors. Our results indicate the need to improve understanding of the interaction/s between these microbial players
