in a Posidonia oceanica meadow and unvegetated sediments of Magalluf Bay (Mallorca Island, Spain) to determine gross primary production (GPP), community respiration (R), and net community production (NCP). From June 2001 to October 2002, we also measured fluxes of dissolved inorganic carbon (DIC) and total alkalinity (TAlk). The yearly integrated metabolic rates based on DO changes show that the P. oceanica communities are net autotrophic while the metabolic rates in the unvegetated benthic communities are nearly balanced. Higher calcium carbonate (CaCO3) cycling, both in terms of production and dissolution, was observed in P. oceanica communities than in unvegetated benthic communities. In the P. oceanica meadow, the annual release of CO2 from net CaCO3 production corresponds to almost half of the CO2 uptake by NCP based on DIC incubations. In unvegetated benthic communities, the annual uptake of CO2 from net CaCO3 dissolution almost fully compensates the CO2 release by NCP based on DIC incubations. CaCO3 dynamics is potentially a major factor in CO2 benthic fluxes in seagrass and carbonate-rich temperate coastal ecosystems. [less ▲]

Même si elles peuvent contribuer de manière très spectaculaire à la maîtrise de la qualité microbiologique des aliments, les techniques de conservation elles-mêmes ne sont pourtant qu’un moyen de maîtrise parmi d’autres… Deux facteurs principaux sont tout simplement la qualité initiale –en particulier la qualité microbiologique- des aliments ou des ingrédients qui les constituent et l’hygiène observée au cours de leur production, de leur transformation et de leur distribution. De plus, un effet « obstacle » n’est reproductible que dans des conditions précises, par exemple pour ce qui concerne le nombre de microorganismes, la composition de l’aliment, les conditions d’ambiance, etc… Une technique de conservation doit donc être validée dans des conditions données (p.ex. par validation de la durée de vie microbiologique permettant d’estimer la D.L.C. d’un produit). Toute modification de ces conditions ne permet plus de garantir la maîtrise de la qualité microbiologique. Il convient par ailleurs d’évaluer l’effet d’une contamination accidentelle de la denrée par un microorganisme pathogène, au cours de sa production, de sa transformation ou de sa distribution (test de croissance après inoculation artificielle de la denrée, encore appelé « challenge testing »). L’établissement et le respect de critères microbiologiques, de bonnes pratiques de fabrication et de procédures d’assurance qualité sont des points clés de la maîtrise de la qualité et de la sécurité sanitaire des aliments. Des progrès significatifs sont en cours et sont encore attendus dans les prochaines années. [less ▲]

The faunaʼs overexploitation in the Congo basin in general and within logging concessions in particular case still appears as a crucial problematic. Commercial poaching threats not only mammal biodiversity but also long-term food safety of local populations. Strangely, this situation is generating a new and collective answer from stakeholders having opposite interests. Administrative authorities, international NGOs of conservation, logging companies have found in the context of wood certifi cation a common deal to begin an anti-poaching action on large landscapes. This study analyses interests of each stakeholder and discusses the place given to populations in this social blending around wildlife. [less ▲]

Lit-on encore les poètes romantiques ? Naufragés de la modernité commençante, ils ont tenté de reprendre souffle dans un monde désenchanté et les voilà engloutis dans les anthologies et les explications de texte convenues. Lamartine ? On ne se souvient guère que du « Lac ». Sainte-Beuve ? Le critique dont Proust a basculé la redondante statue a tué le poète. Vigny ? Trop sévère et trop sensuel à la fois pour nos hédonismes obligatoires. Hugo ? Il n’est plus question que du romancier. Musset ? On le joue encore au théâtre, sa poésie est dévaluée. Nerval ? Trop grandi, il est la victime de l’hermétisme qu’on lui suppose. Les « petits romantiques » ? Nous ne les connaissons plus guère que par Baudelaire interposé. La poésie moderne est incompréhensible coupée du moment romantique qui la propulse en premier et avec lequel elle rompra les amarres. Baudelaire, Lautréamont, Rimbaud, Mallarmé, Apollinaire même seront tous comptables de l’effraction que le romantisme a produite au sein du champ littéraire de la première moitié du siècle. Un sujet, un monde, un langage. Et entre ces instances, une circulation, des médiations, mais aussi des tensions et des blocages. C’est de ce romantisme-là, loin des mythes et des routines, qu’il s’agit ici de retrouver l’énergie et la force d’invention. Au plus près des textes et de leur mise en dialogue, et dans le rapport si complexe qu’ils entretiennent avec l’histoire. Histoire d’un sujet lyrique, qui se dit et qui se pense. Histoire d’un monde qui se transforme et que la poésie tente de sonder. Il faut prendre la poésie au sérieux : voilà ce que les romantiques, les premiers à l’âge moderne, ont fait savoir. Voilà pourquoi il faut aussi les prendre au mot. [less ▲]

This text, wihch is conceived as a historical-critical introduction to Heinrich Rickert's polemical article "The Two ways of the Theory of Knowledge" (Kant-Studien, 1909), is a substantive commentary on the Rickert-Husserl relationship. Discussed topics include: antipsychologism and the view of logic as a normative or theoretical science, theory of obviousness (is obviousness a mere subjective feeling? or is it something else? what is its function in our knowledge procedures?), nature of judgement and truth (what kind of "act" do we perform when we perform a judgement? what is a true judgement? is truth analysable in terms of the correspondance-theory? or is truth a "transcendent" value, which is merely assumed - or not - by the judging agent?), heterological relation between subject and object, etc. Those topics are examined within a broader framework, namely starting from the methodological distinction between "noetical analysis" (or act-analysis) and "noematical analysis" (content-analysis), which can be regarded at some extend as common to Husserl and Rickert.

Acetaldehyde is the first active breakdown product (i.e., metabolite) generated during alcohol metabolism. It has toxic properties but also exerts other actions on the body (i.e., has pharmacological properties). Recent studies have shown that the direct administration of acetaldehyde, especially into the brain, induces several effects that mimic those of alcohol. High doses of acetaldehyde induce sedative as well as movement-and memory-impairing effects, whereas lower doses produce behavioral effects (e.g., stimulation and reinforcement) that are characteristic of addictive drugs. When acetaldehyde accumulates outside the brain (i.e., in the periphery), adverse effects predominate and prevent further alcohol drinking. To investigate the role of acetaldehyde in mediating alcohol's effects, investigators have pharmacologically manipulated alcohol metabolism and the production of acetaidehyde within the body (i.e., endogenous acetaldehyde production). Studies manipulating the activity of the enzyme catalase, which promotes acetaldehyde production in the brain, suggest that acetaldehyde contributes to many behavioral effects of alcohol, especially its stimulant properties. However, it remains controversial whether acetaldehyde concentrations obtained under normal physiological conditions are sufficient to induce significant pharmacological effects. Current evidence suggests that the contribution of acetaldehyde to alcohol's effects is best explained by a process in which acetaidehyde modulates, rather than mediates, some of alcohol's effects.

The increased concern about environmental effect of off-target deposits of pesticides use has resulted in the development of numerous spray drift models. Statistical models based on experimental field studies are used to estimate off-target deposits for different sprayers in various environmental conditions. Random-walk and computational fluid dynamics (CFD) models have been used to predict the effect of operational parameters and were extensively validated in wind tunnel. A third group, Gaussian dispersion models have been used for several years for the environmental assessment of the pesticide spray drift, mainly for aerial application. When these models were used for the evaluation of boom sprayer spray drift, their predictions were found unreliable in the short range, were the initial release conditions of the droplets have a significant effect on the spray deposits. For longer ranges, the results were found consistent with the field measurements as the characteristics of the source have a reduced influence on the small droplets drift. Three major parameters must be taken into account in order to define realistic initial conditions of the droplets in a spray drift model: the spray pattern of the nozzle, the boom movements and the effect of entrained air and droplet velocities. To take theses parameters into account in a Gaussian model, the nozzle droplet size distribution measured with a Malvern laser particle analyser was used to divide the nozzle output into several size classes. The spray deposits of each diameter class was computed for each successive position of the nozzle combining the nozzle spray distribution with drift computed with a Gaussian tilting plume model. The summation of these footprints resulted in the global drift of the nozzle. For increasing droplet size, the release height used in the Gaussian model was decreased from nozzle height to ground level using an experimental law to take into account the effect of entrained air and droplet initial velocity. The experimental law was adjusted on 2m/s wind tunnel measurements and robustness was evaluated for 1 and 4 m/s. [less ▲]

Relative drift potential was evaluated for three types of hydraulic nozzles (a flat-fan nozzle, a hollow cone nozzle and an air induction nozzle) spraying different liquids: water, emulsifiable concentrate (EC) and suspension concentrate (SC) formulations of phenmedipham dispersed in water, with or without addition of 4 different tank-mix adjuvants. The droplet size spectra were measured for these 15 spray mixtures using a Malvern Particle Sizer and characterised by the Volume Median Diameter (VMD) and the percentage of liquid contained in droplets less than 100 m (% < 100 m). Horizontal ground drift was measured in a wind tunnel, on glass fibre collectors using a fluorescent tracer dye technique. The relative drift of each spray mixture was characterised by the Drifted Part (DP) which is the part of the sprayed volume drifted between 2 and 6 metres. Although the nozzle type was the predominating parameter regarding to the droplet size spectra and the DP, differences were observed due to the liquids characteristics. The EC formulation produced a smaller droplet size and a greater DP than the SC formulation whatever the tank mix adjuvant used. For the different spray mixtures, the DP was poorly correlated to the VMD or the % < 100 m. However, correlations between the VMD, the % < 100 m and the DP of the flat-fan nozzle and of the hollow cone nozzle were significant. This suggests that a reference nozzle could be used to estimate the drift potential of other nozzle with a similar liquid sheet break-up mechanism. [less ▲]

Les pouvoirs adjudicateurs désirant avoir une consommation responsable, favorable au développement durable, hésitent souvent à insérer des considérations "autres que strictement économiques" dans leurs procédures d'achat et donc à valoriser les spécificités des entreprises d'économie sociale. Mais d'où vient cette hésitation? L'argument généralement avancé est le fait que l'insertion de considérations autres que strictement économiques va à l'encontre de la logique de marché imposée par la législation nationale, le droit communautaire ou encore l'Accord sur les marchés publics.

BACKGROUND: Patients with schizophrenia are at high risk of developing metabolic abnormalities. METHOD: A prospective study focusing on metabolic disturbances in patients with schizophrenia, including an oral glucose tolerance test, is currently ongoing at our University Hospital and affiliate services. The prevalence of metabolic abnormalities at baseline was assessed in a cohort of 415 patients with schizophrenia. The sample was divided into 4 groups according to duration of illness: first-episode patients (<1.5 years), recent-onset patients (between 1.5 and 10 years), subchronic patients (between 10 and 20 years) and chronic patients (>20 years). RESULTS: Metabolic abnormalities were already present in first-episode patients, and considerably increased with increasing duration of illness. When compared to the general population matched for age and gender, much higher rates of the metabolic syndrome (MetS) and diabetes were observed for patients with schizophrenia. For MetS, the increase over time was similar to that of the general population. In contrast, the difference in the prevalence of diabetes in patients with schizophrenia and the general population dramatically and linearly increased from 1.6% in the 15-25 age-band to 19.2% in the 55-65 age-band. CONCLUSION: Thus, the current data suggest that on the one hand metabolic abnormalities are an inherent part of schizophrenic illness, as they are already present in first-episode patients. On the other hand, however, our results suggest a direct effect of the illness and/or antipsychotic medication on their occurrence. The data underscore the need for screening for metabolic abnormalities in patients diagnosed with schizophrenia, already starting from the onset of the illness. [less ▲]

La prescription de plus en plus fréquente du dextropropoxyphène (DP) et du tramadol, deux antalgiques opioïdes, a conduit les membres du groupe de travail "Toxicologie hospitalière" de la Société Française de Toxicologie Analytique (SFTA) à étudier leur toxicité clinique observée. L'étude a consisté en l'analyse des cas où l'une ou l'autre de ces molécules a été identifiée au décours d'un screening toxicologique réalisé durant l'année 2004 dans les laboratoires hospitaliers des membres de ce groupe. Pour chaque patient ont été recueillis les données démographiques, les concentrations plasmatiques en dextropropoxyphène, norpropoxyphène (NP) ou tramadol, la concentration plasmatique en paracétamol, les médicaments associés et les signes cliniques (digestifs, respiratoires, cardiaques et neurologiques). Aucune relation entre les concentrations plasmatiques de dextropropoxyphène et de paracétamol, ni entre celles de dextropropoxyphène ou de tramadol et la gravité clinique n'a été observée. Les concentrations plasmatiques observées en dextropropoxyphène sont faibles mais doivent attirer l'attention sur une éventuelle intoxication au paracétamol. Les concentrations plasmatiques en tramadol peuvent être élevées mais les intoxications sont dans l'ensemble peu sévères et les concentrations toxiques semblent très supérieures à la concentration de 1 mg/L.
