Pain is a phenomenon in which subjectivity plays a major part. It can be experienced as the contrary to pleasure, or said to be a displeasure coming from the exterior that must be gotten rid of. Otherwise it can be an inner experience that lasts and becomes chronic to the subject's detriment but through which, concurrently, he defines himself. In this case it is closer to «negative» enjoyment that imposes itself on the subject in space and time. An eminently psychosomatic experience, pain in psychical economy as well as an existential experience is a function of the subjective experience. We will draw our clinical material from chronic lumbago and develop the idea that the status of pain depends for a great part on what the patient does with it. Either it is a biological, psychical or social fate or it is a symptom of his difficulty of being.

A 12-month active biomonitoring study was performed in 2008-2009 on a northern French river system using the freshwater mussel Dreissena polymorpha as a sentinel species. Allochtonous mussels originating from a reference site (Commercy) were caged at four sites (Bouy, Sept-Saulx, Fismes, Ardre) within the Vesle River basin. The main objective of the study was to characterize the influence of biotic (sex, food availability) and abiotic (temperature, chemicals) factors on the reproductive and energy reserve (glycogen, lipids) cycles of exposed mussels. Both cycles were markedly disturbed at the Bouy and Sept-Saulx sites where the lowest chlorophyll a levels were recorded during the study. At these sites, mussels obviously faced a negative energy balance, as confirmed by the impairment of their physiological state and byssal attachment. At other exposure sites, reproductive and energy reserves cycles were less impacted but were still dependent on the nutritional state of mussels. The latter appeared as a significant natural confounding factor in ecotoxicological survey performed in low polluted areas. © 2011 Elsevier Ltd.

This is a summary of the Ph. D. thesis defended by the author in December 2009 at École des Mines de Nantes and Universidad de los Andes in Bogotá. The thesis was advised by Christelle Guéret and Andrés L. Medaglia and co-advised by Bruno Castanier and Nubia Velasco. The manuscript is written in English and it is available from the author upon request. The focus of the dissertation is to study real-world vehicle routing problems (VRPs) in uncertain environments. First, the thesis proposes a set of new methods for the VRP faced by a public utility and reports how these methods were embedded into a decision support system. Second, the thesis introduces a stochastic VRP widely found in practice but never studied in the literature before: the multi-compartment VRP with stochastic demands (MC-VRPSD). To solve the problem the dissertation proposes a set of solution methods that offer different tradeoffs between accuracy, speed, simplicity and flexibility. Lastly, the thesis proposes two multiobjective approaches to address the risk behavior of decision makers towards the cost spread in stochastic routing problems and applies them to the MC-VRPSD. © 2010 Springer-Verlag.

The project is a concept which is very much in vogue and which is indicative of a search for meaning in hospitals. It is a fragile undertaking steeped in challenges and threatened by three major trends: voluntarism, idealism and technicism. Projects must create the conditions which enable the individual or collective existence to give itself meaning to build and rebuild. © 2013 Published by Elsevier Masson SAS.

To characterize the eel contamination by dioxin-like (dl) and non dioxin-like (ndl) polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), sixty-two eels from the Loire estuary (France) were analyzed. PCB contamination significantly increased from glass eel stage (3.71±1.85 and 15.2±4.2ngg-1 dw) to other life stages (for yellow eels: 62.8±34.4 and 382±182ngg-1 dw; for silver eels: 93.7±56.3 and 463±245ngg-1 dw respectively for dl and ndl-PCBs). An inter-site variability based on PCB levels and profiles was observed among the three studied sites. For glass eels, the profile was mainly characterized by less chlorinated PCBs contrary to the other eels, displaying a different bioaccumulation pathway. Overall, the contamination level in the eels from this estuary was shown to be low for PCDD/Fs and intermediate for dl and ndl-PCBs, compared to other international/national areas. However, more than 60% of the studied silver eels displayed higher values for PCDD/F and dl-PCB WHO2005 TEQ than the EU permissible level of 10pgg-1 ww. This statement suggests a potential exposure to PCBs through eel consumption, especially with silver eels, and also points out apparent contamination that could eventually affect the reproductive success of the species. © 2013.
