    The whole of the experimental methods described (animal preparation, achievement of a precise physiological technique, dosimetry, biological information processing) allowed us to follow the changes for 15 days in the spontaneous and evoked electroencephalogram activities of rabbits submitted to a non-lethal 400 rads whole-body gamma-irradiation. Behavioural troubles, changes in the arousal state and the spontaneous electrical activity of the neo-cortex and hippocampus were noticed constantly together with an enhanced cortical excitability, and the appearance of elements of the paroxystic series sometimes in contrast with a general decrease in amplitude. After a visual stimulus the general morphology of evoked activities at the level of the primary visual areas and hippocampus was unchanged, but enhanced latencies and delays, less systematic modifications in amplitudes seemed to show out a direct effect of radiations on the nervous system and sensorial activities; these troubles seemed to occur independently from the basic electrical activity. As a whole, the changes observed were usually transitory and varied with each individual. Finally an assumption is made to explain the mechanism of arousal troubles and the general evolution of spontaneous electrical activity in the brain. (author) [French] 'L'ensemble des methodes experimentales decrites (preparation des animaux, mise au point d'une technique physiologique precise, dosimetrie, traitement de l'information biologique) a permis de suivre, pendant 15 jours, chez le lapin soumis a une irradiation gamma globale non letale de 400 rads, les modifications des activites electroencephaliques spontanees et evoquees. De facon constante, on note des troubles du comportement, des modifications de la vigilance et de l'activite electrique spontanee du neo-cortex et de l'hippocampe, ainsi qu'une augmentation de l'excitabilite corticale, l'apparition d'elements de la serie

    Full Text Available Alors qu�elle est actuellement oubliee dans les pays developpes, la syphilis congenitale se voit encore chez nous faute du depistage antenatal. Ses formes cliniques sont polymorphes et orientent a tord vers d�autres pathologies surtout en periode neonatale. Le diagnostic n�est donc pas toujours facile. La revelation d�une syphilis congenitale par une fracture spontanee est exceptionnellement decrite. Nous rapportons dans ce travail le cas d�un nourrisson de 2 mois ramene en consultation pour limitation douloureuse des mouvements du bras droit. Le diagnostic est evoque sur les donnees radiologiques et confirme par la serologie syphilitique. Le traitement a repose essentiellement sur l�administration de la penicilline G avec une bonne evolution clinique.

    oesophageal perforation, CT showed the presence of a intramural haematoma in one case, oesophageal fluid distension with gas and a small peri-oesophageal fluid effusion (Mallory-Weiss syndrome) in another, and oesophageal rapture (Boerhaave syndrome) in the last case. Conclusions: Our experience shows that in patients with suspected traumatic and spontaneous oesophageal perforation, standard cervical and chest radiography may suggest a suspected oesophageal perforation in only a small proportion of cases, whereas oral contrast oesophagography has a higher sensitivity. Through the careful analysis of suggestive and specific signs of oesophageal perforation, a correct CT examination enables an accurate and timely diagnosis which significantly affects prognosis and provides valuable indications for treatment. [Italian] Scopo: Presentare la nostra esperienza relativa al ruolo della TC nello studio delle perforazioni traumatiche e spontanee dell'esofago. Materiale e metodi: Da marzo 2001 a maggio 2003 sono giunti alla nostra osservazione 12 pazienti (7 di sesso maschile, 5 di sesso femminile, di eta' compresa tra 25 e 66 anni, eta' media 43,5) con sospetta lesione esofagea da incidente stradale (in 4 casi), ferita d'arma bianca (un caso), post-intubazione (2 casi), da indigestione di corpo estraneo (2 casi) e di tipo spontaneo (3 casi). Cinque pazienti praticavano l'esame standard del torace e della regione cervicale. In 2 pazienti con sospetta indigestione di corpo estraneo veniva somministrato gastrografin per os. In tutti i 12 casi veniva eseguito l'esame TC del collo-torace-addome senza e con mdc ev e con mdc idrosolubile per os in 4 casi. Risultati: Nei 5 pazienti con trauma cervico-toracico-addominale l'indagine TC evidenziava oltre a lesioni traumatiche pleuro-parenchimali (pneumotorace, versamento pleurico ed enfisema sottocutaneo) anche reperti suggestivi di perforazione esofagea: aria mediastinica in sede periesofagea (5 casi), fluido

  1. L’activité peut-elle être objet d’ “analyse”? = A atividade pode ser objeto de “análise”?

    Directory of Open Access Journals (Sweden)

    Schwartz, Yves

    2015-01-01

    Full Text Available Dans le cadre d’une confrontation entre divers chercheurs de sciences humaines sur le concept d’activité, ce texte trace d’abord une brève histoire de ce concept tel que la démarche ergologique l’a progressivement construit, à partir de son histoire philosophique et des rencontres que ses protagonistes ont pu faire depuis plus de trente ans. Avec le concept d’activité comme dramatique d’usage d’un corps-soi, une vision anthropologique s’est peu à peu imposée: l’activité comme renégociation permanente des normes générées et/ou instituées dans l’histoire apparaît comme la forme spécifiquement humaine du vivre, le travail étant en son sein un lieu particulièrement dense de débats avec ces normes dont le corps-soi est le creuset. Le texte propose alors d’approfondir les implications de ce concept de débat de normes, comme fabricateur d’histoire, comme reproblématisant le champ de l’épistémologie, comme convoquant un univers axiologique au creux de tout agir individuel et collectif. A l’approcher ainsi, ce concept déplace le problème des rapports micro/macro, déterminations sociales/ créativités singulières, des divers empans temporels où nous avons à traiter ces débats, des niveaux innombrables où ils se jouent au sein de notre corps-soi. Ce texte en conclut que si le concept d’activité est ainsi approché, l’idée qu’on puisse en avoir des “méthodes d’analyse” paraît peu acceptable. Par contre, avec l’aide de toute méthode désimplifiant le travail, l’effort d’analyse du travail comme activité nous paraît à développer, pour donner visibilité et avenir aux réserves d’alternative que tout agir humain produit sans relâche

    The changes of bioactive constituents were analyzed for Puhuang-Wulingzhi before and after compatibility and the antiplatelet and antithrombin activitives were evaluated in order to elucidate the scientific and reasonable of Puhuang-Wulingzhi compatibility. UPLC-QTOF-MA-Markerlynx, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis were used for data analysis and tracking changes of chemical composition during the decocting process. In vitro platelet aggregation induced by ADP, thrombin time(TT) and prothrombin time (PT) were investigated for Puhuang-Wulingzhi before and after compatibility. The results showed that significant differences were found between the mixed decoction and codecoction of Wulingzhi and Puhuang. Five compounds changed obviously were identified as typhaneoside, naringenin, isorhamnetin-3-O-ruinoside, quercetin-3-O-neohesperidoside, kaempferol-3-O-neohesperidoside. The codecoction, comparing with the single decoction, was more significant in antiplatelet aggregation and could prolong thrombin time. In the same crude drug dose, the thrombin time (TT) elongation were greater. These data could provide references for elucidation of bioactive components for this herb pair. PMID:26790290

The use of a 4{pi} counter permits to get the absolute activity of all beta radioactive source, susceptible to be put as thin leaf and of period superior than some minutes. The method is independent of the spectra of the measured radioelement. we will describe in the second part some applications which use neutron densities measurement, neutron sources intensities and ratio of cross sections of capture of thermal neutrons.

    S i, en première approche, on définit l'entrepreneuriat du luxe comme celui qui vise l'exploration et l'exploi-tation d'opportunités d'affaires intenses en savoir-faire, alors on obtient une opposition entre activités tirées par les hautes technologies « High tech » et celles poussées vers ces savoirs indissociables des acteurs qui les portent ou « Human tech ». Cette opposition est factice et va à l'encontre même d'une transversalité des disciplines pour la conduite des organisations. Autrem...

    Des enregistrements continus d'activité locomotrice ont été effectués sur des souris mâles isolées des lignées Balb/c et C57bl/6, vivant en cages d'élevage ou en milieu semi- naturel. Les résultats montrent que les différences entre ces deux situations ne sont pas perçues de la même façon par les animaux des deux lign'ees: alors qu'en cages d'élevage les souris des deux lignées experiment la même quantité totale d'activaté, en milieu semi-naturel les souris Balb/c sont plus actives que les C57bl/6. En outre, l≐s différences observées entre les lignées pour la repartition de l'activité au cours du nycthèmere s'inversent lorsque l'on passe d'une situation à l'autre. L'étude de la variabilité fait aparaître une dispersion plus grande des performances dans la lignée C57bl/6 en cages d'élevage, alors qu'en milieu semi-naturel la dispersion est plus chez Bal/c.

    The present account based on experience acquired in the Biology Service, in measuring feeble activities of tritium and carbon-14 has been prepared for the benefit hose who have to carry out measurements of feeble activities using ionization chambers. Precision are given on the behaviour and actual performance of vibrating condenser electrometers, based on approximately two years operating experience. It is shown that the possibilities of utilisation are not limited as is generally believed by insufficient sensitivity and stability of the electronic equipment, but by the existence of various parasitic phenomena coming from the ionization chamber itself, which make very difficult the measurement of ionization currents which are less than 10{sup -14} A.

Il donne des precisions sur le comportement et les performances reelles des electrometres a condensateur vibrant, basees sur environ deux ans d'utilisation, et demontre que les possibilites de mesure ne sont pas limitees - comme on le croit generalement - par l'insuffisance de sensibilite et de stabilite de l'appareillage electronique, mais par l'existence de divers phenomenes parasites dont la chambre d'ionisation est le siege et qui rendent tres difficiles la mesure de courants d'ionisation inferieurs a 10{sup -14} A.

    Full Text Available Le journaliste professionnel est défini en France par une loi de 1935 dont les dispositions sont inscrites dans le Code du travail. Il est notamment caractérisé par rapport à « l’exercice de [sa] profession » dont le contenu n’est pas précisé. Depuis 1936, une commission paritaire (CCIJP est chargée de délivrer une carte d’identité de journaliste professionnel (carte de presse. En cas de refus, le demandeur peut s’adresser à une commission d’appel (CSCIJP puis à la juridiction administrative. Ces acteurs opérationnalisent la définition du journaliste professionnel en évaluant à partir de cas concrets en quoi consiste l’activité journalistique. À partir d’une analyse qualitative du « travail juridique » de ces acteurs en charge de délivrer la carte de presse (entretiens, observations, décisions des instances et jurisprudence du Conseil d’État, on montre qu’ils ne peuvent se fonder uniquement sur une application concrète de la loi. Leur évaluation de la nature de l’activité doit être justifiée. Les arguments (dans les discours et dans les décisions ont été classés « à la main » selon un « arbre de classification » qui fait apparaître plusieurs regroupements qui se rattachent au même principe d’évaluation.

    Full Text Available Glossina palpalis gambiensis et G. tachinoides sont des vecteurs majeurs des trypanosomoses humaines et animales en Afrique de l’Ouest. Sur une partie de leur aire de répartition, elles sont présentes en sympatrie, mais très peu d’informations sont disponibles sur leurs interactions. Nous avons capturé ces deux espèces en utilisant un système attractif composé d’écrans de tissu noir/bleu/ noir muni de film adhésif, afin de retenir toutes les glossines posées et de pouvoir mesurer la hauteur à laquelle elles se sont posées, ainsi que leur rythme d’activité en fonction de l’heure de la journée. L’étude a eu lieu dans deux zones du sud du Burkina Faso : Kartasso en amont du fleuve Mouhoun, où seule G. p. gambiensis est présente, et Folonzo sur le fleuve Comoé, où les deux espèces cohabitent. Les résultats, sur 3 800 glossines capturées, montrent une forte prédominance des captures de G. tachinoides par rapport à G. p. gambiensis à Folonzo (84 % contre 16 % des captures respectivement. À Kartasso, où elle est seule, G. p. gambiensis est capturée en moyenne à 46 cm du sol. À Folonzo, G. p. gambiensis est en moyenne attrapée à une hauteur de 65 cm, et G. tachinoides à 55 cm, ces différences de hauteurs étant significatives. Les femelles sont capturées en général plus haut que les mâles. Les deux espèces montrent un rythme d’activité similaire en fonction de l’heure de capture, mais seule G. p. gambiensis réduit sa hauteur de vol aux heures les plus chaudes. Plusieurs hypothèses, non exclusives, sont évoquées pour expliquer ces hauteurs de capture différentes : la nature de la galerie forestière, un comportement d’approche qui différerait entre espèces, mais aussi la possibilité de phénomènes de compétition interspécifique en relation avec l’utilisation de ressources énergétiques limitées (métabolisme lié à la proline. Sont également discutées les conséquences possibles

Les 4 groupes de cobayes nommés A, B, C et D en raison de 3 cobayes par groupe, ont chacun reçu d’abord une surcharge en glucose en concentration égale. En plus, les différents groupes ont reçu respectivement la solution du glibenclamide (A, l’extrait aqueux des feuilles de Vitex madiensis (B, la solution du résidu méthanolique (C et l’eau distillée (D. Avec le glibenclamide, on constate une diminution de la glycémie de plus de 25 % dès la 75e minute après une augmentation de 113,2% à la 30e minute tandis qu’avec l’extrait aqueux de feuilles de Vitex madiensis on a une diminution de la glycémie de 13 % dès la 75e minute après une augmentation de 130% à la 30e minute. Avec le résidu méthanolique et l’eau distillée il y a une diminution respective de la glycémie à la 120e minute et à la 210e minute après une augmentation importante à la 30e minute. Les résultats trouvés montrent que le traitement par l’extrait aqueux des feuilles de Vitex madiensis a donné des effets similaires à ceux obtenus avec le glibenclamide sur les cobayes surchargés en glucose, ceci nous a poussés à dire que l’extrait aqueux de cette plante est doué d’une activité hypoglycémiante remarquable. Our study had the objective to estimate the hypoglycemic activity of Vitex madiensis, a plant used in antidiabetic phytotherapy, on animals of laboratory chosen as material of experience. Four groups of guinea pigs named A, B, C and D in reason of 3 guinea pigs by group, receive at first an excess load in glucose concentration.

Le pouvoir antioxydant est évalué par le test au DPPH et le test de blanchissement du β-carotène. L’activité antibactérienne vis-à-vis de neuf souches bactériennes (deux à Gram positif et sept à Gram négatif est évaluée par la méthode des aromatogrammes et la méthode de dilution d’agar pour déterminer les CMI. L’extraction a donné un rendement moyen de 1,34±0,012%. Cette huile essentielle a montré des propriétés antioxydante et antibactérienne importantes. La concentration efficace qui réduit 50 % du DPPH en solution est de 0,09±0,001 µg/ml qui exprime une activité antioxydante plus importante que celle de α-tocopherol, ce résultat a été confirmé par le test de blanchissement du β-carotène. Les bactéries testées ont montré une sensibilité à l’huile essentielle. Ces activités sont liées à la richesse de l’huile essentielle en monoterpènes (81,01%.

    Full Text Available Il est généralement admis que la compétence langagière est un facteur de réussite des études supérieures. Or, plusieurs professeurs d’université soulèvent l’incompétence d’un nombre croissant de leurs étudiants en ce qui a trait à la maîtrise du français. Malheureusement, même si elle est reconnue comme cruciale à l’université et malgré les problèmes évidents des étudiants universitaires concernant la compétence langagière, cette dernière n’y est pas enseignée et même rarement évaluée dans le cadre des cours disciplinaires. C’est dans cette optique que nous nous sommes intéressées à la place accordée à la compétence langagière dans des programmes professionnels dans le secteur de l’éducation. Notre objectif de recherche est donc de caractériser les activités d’évaluation de la compétence langagière. L’utilisation d’analyses de construits a révélé des différences dans l’évaluation par rapport aux caractéristiques suivantes : 1 composantes linguistique et communicative ; 2 évaluations formatives et sommatives ; 3 productions orale et écrite ; et finalement 4 évaluation individuelle ou collaborative.It generally accepted that superior language skills are an important factor when it comes to succeeding in post-secondary education. Even though it is recognized that superior language skills are important for academic achievement and that most new students do not possess these skills, these are not being taught and are rarely evaluated in undergraduate courses. Most university professors are finding that an increasing number of students have inferior or low level language skills in French language. Our research examines the importance placed on language skills in teacher education programs with the objective of analyzing the characteristics of activities used to evaluate language skills in these programs. Our findings show that there are differences in the evaluation

    Durante la Edad del Bronce en Europa occidental, el aumento drástico de la producción de cobre apenas está documentado en las actividades mineras y metalúrgicas de transformación. En este contexto, el yacimiento minero y metalúrgico de Saint-Véran, Hautes-Alpes constituye un testimonio privilegiado de la producción en masa a fines del III milenio, ya que las obras mineras dan cuenta de una explotación a gran escala, con una producción de casi 7 t de cobre al año. Numerosos sitios de metalurgia extractiva puede haber estado asociados con ella. Desde hace 20 años, diversos equipos, como en el que participan los autores, han emprendido o emprenden investigaciones para intentar documentar el sitio y su actividad. El objetivo de este artículo es presentar el estado actual de la cuestión sobre el yacimiento. Los resultados principales son la puesta en evidencia de la actividad de producción en masa y su cuantificación. Además se ha descrito por primera vez la organización de la producción, poniendo en evidencia la sucesión de fases entre la actividad minera y metalúrgica, así como las técnicas metalúrgicas innovadoras puestas en práctica. El yacimiento revela un estallido muy marcado de la actividad metalúrgica en el espacio que no deja de plantear interrogantes. Igualmente, la cuestión del destino de la producción sigue abierta por completo. Por otro lado, los motores para una implantación semejante en un territorio de alta montaña han comenzado a identificarse. Así se invocan determinismos naturales ya se trate de la mineralización particular de un yacimiento como de la evolución del clima.

    Full Text Available De nombreuses publications font l'état de l'action négative du cadmium (Cd++ sur la vitellogenèse chez les poissons. Le mécanisme d'action de ce métal n'étant pas clairement établi, une étude a été entreprise afin de déterminer si l'effet du cadmium passait par une action sur l'activité biologique du récepteur des oestrogènes de la truite arc-en-ciel (rtER. Cette étude a été réalisée dans un système de levures recombinantes, exprimant de manière stable rtER, et dans des hépatocytes de truite en culture primaire. Dans la levure, rtER activé par l'oestradiol (E2 contrôle spécifiquement l'expression d'un gène rapporteur codant pour l'enzyme ß-Galactosidase. Une concentration en Cd++ de 10 µM diminue de 45 % l'expression stimulée par l'oestradiol du gène rapporteur dans les levures recombinantes. De même, dans les hépatocytes, l'expression du gène de la vitellogénine (VTG, gène sous le contrôle positif de E2, est diminuée de 65 %. Le cadmium n'affecte pas la liaison de E2 à son récepteur et seule l'activité hormonodépendante est affectée par ce métal. Les résultats de cette étude montrent que l'effet négatif du cadmium sur l'action de l'oestradiol passe vraisemblablement par une action directe de ce métal sur la fonction de transactivation hormono-dépendante de rtER.

À cette fin, il essaiera surtout de suggérer quelques pistes de travail et des moyens de les poursuivre. Il commencera par dégager quelques traits essentiels de cette notion et en proposera un modèle. Cette notion sera aussi articulée à celle de règle. La deuxième partie montre comment le modèle de régulation proposé permet d’éclairer l’analyse de l’activité, en même temps que celle-ci amène à enrichir ce modèle. Elle fera apparaître, notamment, la multiplicité des boucles de régulation susceptibles d’être exploitées dans l’exécution d’une tâche et le rôle important que peut jouer la métarégulation dans l’organisation de l’activité. La troisième partie, plus concrète, examinera quelques types d’usage de la régulation dans des études d’orientation ergonomique. Elle en donnera un petit historique, puis abordera des thèmes autour desquels se sont organisées de telles études, en particulier, la place des cadres temporels, les activités collectives et la formation. La conclusion reviendra sur l’intérêt d’un bon usage de la notion de régulation et indiquera quelques limites à son utilisation.The following text aims to show the benefit for activity analysis obtained through a better knowledge of the concept of regulation, which is often poorly defined. To achieve this, it above all tries to suggest some avenues of study and some means for following these avenues. It begins by identifying some essential characteristics of this concept, and proposes a model for it. This concept will also be articulated with that of a rule. The second part shows how the proposed regulation model elucidates activity analysis at the same time that the latter enriches this model. It reveals the many regulation loops that can be used

    Full Text Available Le grand commerce est un secteur d’activité où la performance économique se mesure à l’échelle des volumes de marchandise distribuée. Derrière cet indicateur se cachent des politiques de gestion des ressources humaines largement déterminées par les questions de productivité du travail. En effet, ces entreprises commerciales ont à résoudre une équation majeure consistant à placer la bonne quantité de personnel au bon endroit et au bon moment, du fait de la forte irrégularité des affluences de la clientèle dans leurs points de vente. L’usage du temps de travail acheté constitue donc une variable fondamentale dans la maîtrise des coûts de production. Les solutions choisies ne sont pas sans incidences sur les conditions temporelles d’exécution du travail des salariés dans les magasins. Leur activité oscille entre intensité et débordement, ce qui impacte fortement leur manière d’appréhender leurs tâches, leurs relations avec la clientèle et leur capacité à vivre sereinement leur travail.Mass retail is a sector where economic performance tends to be measured by the volume of goods distributed – an indicator built upon human resource management policies that are largely rooted in the productivity of labour. Commercial companies are constantly seeking to move large numbers of staff members to the right place at the right time, a complicated exercise given customers’ irregular presence at points of sale. The way that companies use the working time that they have purchased therefore constitutes a key variable in controlling production costs. The solutions they choose will affect the temporal conditions determining employees’ in-store execution of tasks. Such activities tend to fluctuate between intensity and overflow. In turn, this strongly affects how staff members apprehend tasks; relations with customers; and their sense of serenity at work.El comercio masivo es un sector de actividad cuyos resultados

    Full Text Available L’article présente la problématique de ce dossier sur les temps sexués de l’activité. Il s’agit d’aborder l’activité − dans une acception large du travail, rémunéré ou non, plus ou moins visible, dans son articulation avec l’ensemble des sphères de la vie − comme miroir de l’imbrication du genre et des temporalités. Deux postures y contribuent. La plus classique consiste en une sociographie de la division sexuelle du travail où le temps sert à mesurer les inégalités. Il faut la compléter par une deuxième qui interroge les catégories temporelles : on montre ainsi que les temporalités sont au principe du système de genre. Ici le temps, appréhendé dans sa diversité et notamment ses dimensions qualitatives, résulte des pratiques et est posé comme producteur de rapports de pouvoir. La domination masculine repose sur la construction du rapport au temps : la naturalisation des compétences dites féminines s’appuie sur une temporalité basée sur le rapport à l’autre et l’engagement dans la durée. Les perspectives théoriques autour du care et de la présence sociale permettent de montrer les implications morales de l’engagement pour autrui dans ses dimensions temporelles (sens de l’anticipation, disponibilité à l’autre, ancrage dans la durée, temporalisation. Les auteurs exposent ensuite la manière dont chacune des contributions du numéro alimente cette discussion.We introduce this issue on the gendered times of work, broadly understood – i.e. paid or unpaid, and more or less visible – which, in conjunction with the other spheres of life, mirror the intricate interplay of Gender and Temporality. Two positions are highlighted. The more classical one is a Sociographics of the gendered division of labour in which time serves to measure existing inequalities.

    Full Text Available In this study, reaction pathway of a woody biomass under hydrothermal conditions is investigated in order to further understand reactions that occur during the thermochemical liquefaction of a lignocellulosic biomass. A multitechnique analytical approach combining chromatographic and spectroscopic techniques has been developed in order to characterize both chemical structure and molecular weight of the products. From our experiments, we can assume that the holocellulosic and the ligneous fractions of biomass have different reactivity under hydrothermal condition. Although hydrothermal conversion of holocellulose and lignin occur both according to a complex pathway composed of competitive fragmentation and condensation reactions, holocellulose reacts first by total fragmentation to low molecular weight compounds followed by the condensation of the fragment to heavy molecular weight compounds, whereas lignin reacts essentially by partial depolymerisation. Since compounds produced from both the holocellulosic and the ligneous fraction are together in the reaction medium then they condense each other during the conversion of lignocellulosic material. Ce travail porte sur l’étude des voies réactionnelles accompagnant la liquéfaction thermochimique du bois et de ses constituants lignocellulosiques lors d’un traitement hydrothermal. Pour ce faire, une approche analytique multi-technique originale combinant des méthodes chromatographiques et spectroscopiques complémentaires a été développée afin de caractériser les structures et les masses moléculaires des produits. Les résultats obtenus montrent que la fraction holocellulosique et la fraction ligneuse de la biomasse ont des réactivités très différentes. Bien que les deux matériaux réagissent selon des schémas réactionnels complexes faisant intervenir de nombreuses voies de fragmentation et de condensation compétitives, la fraction holocellulosique réagit par une première

En adoptant le point de vue de l’activité, nous montrons que la compréhension et la prévention de ce risque nécessitent de connaître et de comprendre l’activité de travail. En effet, l’activité de conduite est une activité de travail et le risque qui lui est lié est un risque au travail. Pour prévenir ce dernier, il est donc nécessaire de dépasser la simple approche comportementale de l’activité de conduite et de prendre en considération l’ensemble des déterminants de l’activité de travail qui font que le conducteur de travaux se déplace et prend des risques sur la route. Nous retiendrons que les aspects organisationnels (prescription, organisation de la production, politique de ressources humaines, matériel (véhicule, outils de communication et interentreprises (relationnel client affectent l’activité de conduite et que la prévention du risque routier nécessite donc une approche globale (aux niveaux individuel et collectif, dans l’entreprise et avec les entreprises extérieures qui touche à ces différents domaines.This paper presents the results of a study on the occupational road risk of workers for whom driving is not their job but who drive frequently: Public Works site supervisors.

In fact, driving is a work activity and the related risk is an occupational risk. To prevent the latter, it is necessary to go beyond the simple behavioural driving activity approach and consider all the determinants of the work activity that cause the work supervisor to drive and take risks on the road

    The measurement and location by gamma spectroscopy of human body internal contaminations at maximum permissible levels, and, in certain cases, at lower activities such as that due to {sup 40}K was investigated. The characteristics of the high-sensitivity apparatus used are given, and several assemblies using large-volume NaI(Tl) scintillators are described. The relatively light shielding required for natural radioactivity permitted construction of mobile assembly. Conditions of use are described, and the results are given. All gamma emitting elements were measured in 15 min at levels lower than the tolerance dose. Gamma spectroscopy was also used to determine fission products in the earth and to study radioactive elements in the presence of other emitters. (author) [French] La spectrographie gamma du corps humain permet la mesure et la localisation des contaminations internes au niveau des doses de tolerance et, dans certains cas, celle d'activites plus faibles comme la radioactivite naturelle due principalement au potassium 40.

Les éléments dégagés indiquent que l'utilisation d'Antidote peut être vecteur d'apprentissage et offrent quelques pistes permettant de concevoir des activités de révision assistée par ordinateur qui s'inscrivent dans le cadre d'une didactique de la production scripturale.This study explores learners' cognitive processes when using the grammar assistant software Antidote during the revision phase of their composition. Analysing data obtained using a hybrid form of verbal protocols, it shows how computer-assisted revision activity can lead learners to manipulate, build or reinforce declarative and procedural knowledge. We argue that using grammar assistant software can be conducive to learning. The results of the analysis provide an insight into how such a tool can be integrated into classroom activities, contributing to writing quality and the acquisition of revision strategies.

    This article presents the results of a study which concerns Instrumented Collective Learning Situations (ICLS) used in higher education and according to different actors's point of view (instructional designer and tutor). Considered actors have been involved in ICLS conception or in their use with students. We determine several forms of ICLS (in terms of scenario, tools, kind of activity) and what educational approaches are adopted by educational actors in their practices. We detail the results of our study, mainly by highlighting the "home-made" approach of the actors, that is based on an opportunist and pragmatic use of available tools in order to fit into the educational contexts.

    In Quebec, hydraulic represents an undeniable source for energy production and therefore needed an engine for economic development. Therefore, proper design and ongoing inspections are necessary to ensure the stability and safety of these structures. Thus, abnormalities in embankment dams should be located in the shortest time. The internal erosion is the main cause of the failure of embankment dams. Consequently, the infiltration of water in dams, which generates the internal erosion, should be detected. Several non-destructive methods have been developed to auscultate these structures and determine the groundwater level in the embankment works. In this project, the self-potential (SP) method was adopted. This method consists in measuring a passive electric field at the surface of the sail. The phenomenon is defined by the electrofiltration circulation water into the porous matrix of a material which generates a measurable electric current to the ground surface. Laboratory tests at the Universite de Sherbrooke were performed to determine the effect of water flow on the electrical properties for different materials. Plexiglas pipe was used for testing and the theoretical model is the Helmholtz-Smoluchowski. During the tests, the influence of hydraulic loading and temperature on the electrical properties of the materials has been checked. The experiments aim at determining the primary relationship between the coupling coefficient and zeta potential using the self-potential (SP) method. The experimental results were compared with values from the literature to confirm the model and protocol used. Thus since that the experimental data are consequent with those theoretical, experimental model adopted can be considered as reliable. This project is a prerequisite for future research that will develop an inversion algorithm to identify and locate anomalies in the embankment dams. Experimental studies have demonstrated that the hydraulic load had a significant effect on the electrical properties of different materials. The coupling coefficient and the zeta potential vary proportionally to the hydraulic load. In addition, the electrical properties underwent change depending on the fluid temperature. Finally, the coupling coefficient and zeta potential of different materials have fluctuated proportionally to the uniformity of each material. For a more uniform material, the coupling coefficient is lower and the zeta potential is higher.

En s’appuyant sur les travaux d’Elias, il s’agit d’étudier la façon dont la messagerie électronique imprime une unité de temps qui structure l’ensemble des activités des cadres et les transforme. L’analyse proposée s’appuie sur une étude de cas qui interroge les transformations des rôles dédiés aux cadres et plus spécifiquement aux cadres de la fonction publique territoriale à travers l’usage du mail. Les résultats mettent en lumière dans un premier temps la façon dont la messagerie structure d’un point de vue temporel les pratiques professionnelles. Celles-ci s’articulent autour de la gestion et de la hiérarchisation continue d’informations reçues sur le mode du flux continu. Ainsi, ce sont des activités de temporation et de synchronisation de l’information qui constituent les nouvelles formes d’exercice de l’activité. En effet, la particularité du travail des cadres au travers de la messagerie est d’intégrer dans une même unité de temps des données au caractère contradictoire. Si l’outil facilite l’intégration en temps réel des multiples niveaux d’activités, il crée paradoxalement une nouvelle forme de dépendance temporelle qui questionne l’autonomie traditionnellement déléguée au cadre.The paper seeks to determine how e-mail helps to restructure supervisory activities. In France, socio-professional categories such as professionals, managers and executives are all classified as supervisors. Based on Elias’ conception of time, the study analyses how e-mail creates time units that structure and transform supervisory activities. A case study involving a local authority is then mobilized to ask questions about how email use has transformed dedicated supervisory roles. Findings reveal that e-mail tends to structure professional practices along

    Full Text Available Nous avons suivi- au moyen de la microscopie électronique à balayage environnementale (MEBE la diffraction X et la spectroscopie d’absorption des rayons X sous rayonnement synchrotron (XANES- la réactivité de certaines phases SiO2 lors du processus de la Réaction Alcali Silice (RAS. Cette réactivité est étroitement liée à la structure locale autour des atomes de silicium ainsi qu’à la présence d’impuretés comme le fer. Dans le cas du silex brut, la raie blanche du seuil K du fer ressemble davantage à celle de Fe3O4 ce qui permet de déduire la présence d’un mélange de Fe2+/Fe3+ dans le silex de départ. Après réaction, l’allure du spectre d’absorption des rayons X au seuil K du fer du silex est conservée avec un léger déplacement de la raie blanche vers les hautes énergies. Cette augmentation montre une prédominance de la valence Fe3+ au détriment de la valence Fe2+. Les résultats montrent que le fer participe à la stabilisation de la structure des phases formées. Cette étude peut être étendue à d’autres éléments traces présents dans la structure du silex de départ. In this study the reactivity of some SiO2 phases under Alkali Silica Reaction (RAS process is followed, using the environmental scanning electron microscopy (ESEM X-ray diffraction and absorption spectroscopy X-ray synchrotron radiation (XANES. This reactivity is closely related to the local structure around the silicon atoms and the presence of impurities such as iron. In the case of flint raw skate white iron K line is more like that of Fe3O4 which allows to deduce the presence of a mixture of Fe2+ / Fe3+ in the flint to start. After reaction, the shape of the spectrum of X-ray absorption K edge of iron in the flint is retained with a slight displacement of the white stripe to high energies. This increase shows a predominance of the valence Fe3+ at the expense of Fe2+ valence. The results show that iron is involved in stabilizing the

L’application de la combustion en boucle chimique (CLC aux combustibles solides est actuellement étudiée à l’Université du Kentucky, au Centre de Recherche de l’Energie Appliquée (CAER dans le but de développer un procédé de gazéification/combustion en boucle chimique pressurisé (PCLC/G afin de générer de l’électricité à partir de charbon. Un des principaux aspects de la combustion en boucle chimique de combustibles solides est la compréhension de l’effet des cendres sur la réactivité des porteurs d’oxygène (OCs. L’effet des cendres sur la capacité de transfert d’oxygène et sur l’aptitude à oxyder le charbon est étudié avec deux porteurs d’oxygène à base d’oxydes de fer. Les cendres utilisées sont des cendres volantes provenant d’une centrale thermique au charbon. Les expériences sont réalisées dans un système composé d’une thermo-balance couplée à un spectrographe de masse (TGMS dans lequel on utilise d’abord 500 mg d’un mélange de cendres/porteurs d’oxygène à différentes concentrations de cendres allant jusqu’à 75 %. Le gaz réducteur est composé de 10 % de H2, 15 % de CO, 20 % de CO2 et de 55 % de Ar; et le gaz oxydant est composé de 20 % de O2 dans Ar. Les réactions d’oxydation/réduction sont quasi totales. D’après ces expériences, les cendres ont une activité propre de porteur d’oxygène, liée à la présence de fer dans les cendres, confirmée par les analyses DRX. Cela génère une augmentation du gain ou de la perte de masse du mélange pendant l’oxydation/réduction. Les vitesses d’oxydation/réduction augmentent avec la concentration des cendres à cause de l’augmentation de la porosité du mélange de porteurs d’oxygène avec les cendres, ce qui permet un meilleur accès des gaz réactifs sur les sites actifs des porteurs d’oxygène.

    This document details the activities, results and achievements of the CSNSM (Center of Nuclear Spectrometry and of Mass Spectrometry) for the 2004 - 2007 period. This document is divided into 8 sections as CNSMS is divided into 8 research groups: 1) nuclear structure, 2) induced fission and exotic nuclei, 3) nuclear astrophysics, 4) atomic masses, 5) solid state astrophysics (micro-meteorites), 6) mass spectrometry through accelerators, 7) solid state physics, and 8) physical and chemical effects of radiations (PCI). An important part of the activities of the CNSMS is linked to the Spiral-2 project that is today's major nuclear program in France. The main contributions are that to the Agata gamma tracking program, to the Desir platform, and to the Super-separator spectrometer S3. In astrophysics, most activities are focused on the understanding of gamma rays emission in the universe and on the enigma of the lithium-6/lithium-7 ratio. In solid state physics, important contributions have been made to the Edelweiss 1 and 2 programs dedicated to the detection of dark matter. PCI activities have focused on crystallo-chemistry of uranium dioxide, and on radiation effects in oxide ceramics, in carbides and in metallic nano-clusters. (A.C.)

    Full Text Available Backgound and Objectives: Psychoneuroimmunology is one of the areas in charge of nurses, as it provides the implementation of an individualized and humanistic practice, perceiving the patient as a whole and aiming at physical and psychological aspects. The objective of this study was to evaluate the activity of Natural Killer (NK cells in women with breast cancer when the relaxation technique was used in nursing interventions and assess the association between the activity of NK cells and the pattern of behavior for stress and coping. Method: This is an experimental study with a quantitative approach, carried out with mastectomized women submitted to chemotherapy. Results: It was observed that NK cell levels, at the 1st measurement, were not statistically different between the control and experimental groups, demonstrating that the control and experimental groups were initially homogeneous. However, the same groups showed significant differences at the 2nd measurement. Conclusion: The nursing intervention using the relaxation technique modified the activity of NK cells, as the women in the experimental group showed increased activity after learning and practicing relaxation techniques.

    Objective: To investigate the effect of spinal cord stimulation (SCS) on pain behavior and activition of microglia in spinal dorsal hom of rate with neuropathic pain (NP). Methods; 20 adult rats were randomly divided into 4groups: (1) control group; (2) SCS group: normal rats with SCS; (3) SNL + shamSCS group;the SCS device was implanted but without SCS; (4) SNL + SCS group: SNL rate with SCS. Mechanical withdrawal threshold (MWT) was detected for 3 consecutive days pre-operation and on the 5 d post-operation. Rats in SCS and SNL + SCS groups received SCS during 2-5 d after the operation, 8 hours each day. Besides, both of SCS group and SNL + SCS group were given a 90 min test before 8 hours SCS, which meant that SCS was applied for 30 rain and the withdrawl thresholds of the ipsi lateral hind paw were assessed at time of 0, 15, 30, 45, 60 and 90 rain. After SCS on the 5 d of post-operation, rats were sacrificed. Immunohistochemistry combined with average optical density ( AOD) analysis was performed to examine the expression of OX- 42 (marker of microglia) in the L5 segment spinal dorsal horn of rats of all 4 groups. Result; (1) The behavior results showed that the MWT in SNL + shamSCS group and SNL + SCS group reduced significantly from 26.00 ± 0.0 g pre-operation to 5.50 ± 0.96 g and 6.40 ± 0.40 g respectively on the 5 d of post-operation (P <0.05). What's more, 30 min after cessation of SCS, the MWT decreased obviously to the pre-SCS level. ( 2) Immunohistochemical results demonstrated that on the 5 d of postoperation, the expression of OX- 42-immunoreactivi-ty in SNL + SCS group was more lower than SNL + shamSCS group, but both of them showed more immunoreactivity than control group and SCS group. The results of AOD analysis also showed that the spinal dorsl hom AOD of SNL + SCS group (1.29 ± 0.28) was remarkably lower than SNL + shamSCS group ( 2.66 ± 0.38, P < 0.05 ) , but still higher than control group(0.14±0.21)and SCS group(0. 24 ±0

    The main direction of research of the Institute of Nuclear Physics at Orsay was the physics of nuclei far from stability line. The high value of the results obtained is due mainly to development of MUST detectors, LISE3 and SPEG spectrometers and use of large size germanium crystals. Important findings in radioactivity, elastic and inelastic scattering, in transfer reactions (in {sup 11}Be for the first time), Coulomb excitation and use of on-line gamma labelling technique, especially applied to neutron rich nuclei around N=20 and 28, are mentioned. Collaborations to projects like EXOGAM, VAMOS, LISE2000 at GANIL as well as the studies on nuclei around {sup 132}Sn at ISOLDE are reviewed. Very promising appear the results obtained with hot nuclei, produced in heavy ion collisions at 30-200 MeV/n and with the new nuclear species produced in relativistic heavy ion collisions. The studies on hadrons in nuclear matter conducted at CERN LHC and GSI at Darmstadt concerned mainly the quark-gluon plasma. The results on J/{psi} suppression obtained by NA50 collaboration appear to signal this state. The studies on hadron structure with the GRAAL experiment at ESRF opened the domain of strange baryon resonances. This first part of the IPNO Report of activity on 1998-1999 has the following content: 1. Accelerators. 2. Targets, sources and injectors. 3. Detectors and related instrumentation. 4. Electronics and data acquisition. In the first chapter there are presented works on R and D on superconducting RF cavities, the contributions to the LHC and IPHI projects, the status of Tandem accelerator and the activities on techniques associated with accelerators. The second chapter deals with the SELPOM polarized electron source, the CIRIL electron irradiator, the production of neutron rich radioactive atoms at PARRNE 1 and 2, the SILFRA laser ion source and the SIHL stable ion separator, HD polarized targets and TANCREDE project. The chapter three reports studies on the chambers of ALICE dimuon spectrometer and for HADES experiment. Also the progress in developing the equipment for G0 experiment, VAMOS spectrometer, the large surface annular telescope and EUROBALL 4 detector is described. Finally in the chapter four there are reported works on developing a peak sensing ADC, a VXI D size card for EXOGAM,and data acquisition systems. The first volume begins with short reports of activity from the technical and general servicing departments. The second volume of the IPNO Report presents the results of the Research Division.

    Among the significant technological achievements of 1998-99, we will note in particular the manufacture of a lower hybrid antenna. This has large size and is shielded from the plasma by side protection incorporating the same technology that is used in the limiter of the CIEL project. This antenna was tested successfully in the autumn 1999; its capacity is 4 MW steady state. Substantial progress was achieved in testing the 118 GHz gyrotrons that are intended to deliver 400 kW with a pulse length of 210 seconds. Pulses lasting some 15.5 seconds were obtained on load during the summer 1999 and were limited only by the performance of the load and by out-gassing. At these pulse lengths, the parameters of the tube are already quasi-stationary. The tests will begin again in the Spring of 2000 with a more suitable load. The very first tests on plasma took place in the Autumn of 1999 showing a strong absorption of the waves by the plasma. Work in the field of the high frequency heating systems focused on problems of local power deposition close to the antenna. This problem is exacerbated, both at the lower hybrid and at the ion cyclotron frequencies, by the need to carry out long pulse discharges. Modelling the localised effects that have been observed contributes to the evolution of the design of both types of antenna and holds out the prospect of fully-validated solutions for the 'next step'. Using the technology developed for the CIEL project in the field of the high heat flux components also made it possible to implement side protections for the antennas that can withstand the temperature rise related to these local effects. Studies in various modes of heating or current drive were continued, in order to explore the corresponding scenarios but also to make progress in modelling the phenomena of wave propagation and absorption. In the field of ion cyclotron waves, the implementation of {sup 3}He minority heating made it possible to identify the conversion of the fast wave into a Bernstein wave. The scenario of coupling the fast wave to the electrons was also studied from the point of view of scenarios relevant to the conditions of the 'CIEL' project. In the field of the lower hybrid waves, we will note in particular the use of the hard X-ray cameras to observe the spatial and energy distribution of the fast electrons, coupled with the observation of the electron cyclotron radiation. This made it possible to carry out fine observations related to the absorption of the hybrid waves. In particular, the reality of the transition to the LHEP mode and the improvement of confinement which it represents, were clearly established. The DRFC carried out a certain number of studies relating to confinement in various modes of plasma. A good confinement mode was obtained with high density and ion cyclotron minority heating. This mode, which brings to mind certain aspects of the 'Enhanced Radiation' mode, developed by the physicists of TEXTOR, has performance equivalent to the 'Elmy-H' mode, foreseen as the basis for ITER. An active programme of research is underway to elucidate the reasons for this good confinement. In particular, the respective roles played by magnetic shear and rotational shear in the stabilisation of turbulence are being studied. (author)

    The 2000-2001 period has seen many facts of importance for the EURATOM-Cea association. The first outstanding fact is the positive evolution of the ITER project because of both the willingness of the partners and the French proposition to the European Union to consider the Cadarache site as the European site. The second outstanding fact is both the installation on Tore-Supra of a new generation of plasma-facing component: the Ciel project and the launch of the Cimes project whose aim is to allow Tore-Supra to reach discharge up to 1000 s. The third outstanding fact is the continuation of experiments in Jet after 1999, end date of the Jet Joint Undertaking. These new provisions aim at maintaining in activity the spearhead of the European program, waiting for a clarification of the ITER situation. Among the results obtained in Jet operations, we can quote those having a direct influence on the ITER performances: - the beneficial effect of a high triangularity on the ELM (edge localized modes) and on the confinement factor at high density, - the real time control of advanced tokamak discharges at quasi steady state, and the theoretical explanation of the current hole (in lower hybrid advanced scenarios, a region with vanishing current density that appears in the plasma centre).

    The Institute of Nuclear Sciences in Grenoble is a merged research unit formed of the IN2P3 of CNRS and Joseph Fourier University of Grenoble. Founded in 1960, to foster theoretical and experimental nuclear physics it evolved continuously particularly in 90`s when its activity got concentrated on the main topics of the research fields `Quarks and Leptons`, `Particles and Nuclei in Universe`, `Hadron Physics`, `Nuclear Matter` and `New Systems in Nuclear Power Generation`. In the first field, research on massive right-handed neutrinos and on supersymmetric particles were initiated in 1996-1997. The experiments for measuring the neutrino magnetic moment are now operational and first results are expected in 1998. To study antimatter and dark matter in the Universe a magnetic spectrometer was built and is to be installed on the future international space station. In Hadron Physics first results are reported on the {eta} photoproduction and t{sub 20} experiment at TJNAF, representing important advances in the field of short-range nucleon-nucleon interaction. The work conducted by the fusion-fission group allowed to get new insight in the mechanisms of fusion of asymmetric systems. Also, important results concerning the superdeformed exotic nuclei were obtained by the nuclear structure team. Finally, the ISNG project on `Accelerator-driven sub-critical reactors` has advanced strongly in the last two years, in the framework of TARC experiment at CERN (collaboration RUBBIA) and SARA. The programs MUSE at MASURCA (Cadarache) utilizing the future accelerator GENEPI, simulation of sub-critical configurations and other relating programs recorded also important progress. In the field of theoretical physics few body problems, quarks or nucleons, particularly for A = 4 have recorded original developments, with significant insights on the meson properties in the nuclear environment

    1997-10-01

    SUBATECH (Laboratory of Subatomic Physics and Associated Technologies) has been created in 1994 by three founding fathers, the Ecole des Mines de Nantes, the University of Nantes and the Institute IN2P3/CNRS. The challenging new idea was to house under one roof groups working in fundamental research as well as those working in applied research. During the first year the experimental activities focused on nuclear collisions at lower energies, e.g. reactions mechanism studies with the detector INDRA at GANIL. The laboratory specialized in the analysis of two particle correlations which allows to study the dynamics and the geometry aspects of the reaction mechanism. In the area of subatomic Physics our teams study the collisions of heavy ions at different energies to investigate the multifragmentation of nuclei or to search for the quark gluon plasma. In the area of associated TECHnologies the accent is on the problems related to nuclear waste, from the `treatment of nuclear waste with new method (GEDEON)` or its interaction with bacteria to the research of the chemistry of Tc, Ac-225 and Bi-213 and the program of alpha-immunotherapy on micro-tumors. In the field of fundamental science, in parallel to the work on simulations for the new projects, the Subatech scientists could start work on prototypes for the experiments ALICE at the LHC at CERN (scheduled for the year 2005) and STAR at RHIC at Brookhaven (scheduled for 1999). The experimental groups work closely together with the theory groups of Subatech. The author of the VENUS model works in Subatech. This internationally known model is amongst the most important code capable to describe many of the SPS data. Another theory group works on the analysis of multiparticle correlations in the WA98 data with the wavelet theory. Finally, a third group is currently studying the multifragmentation in the final state at GANIL

    1998-04-01

    This report presents the activity of `Laboratoire de Physique Corpusculaire` of Caen from July 1993 to June 1995. From its inception, at GANIL the nuclear physicists aimed at creating far off-equilibrium nuclear systems in order to obtain a better understanding of their properties as well as of nuclear matter. The first direction of research was the study of the excited nuclear matter i.e. the way in which the energy of heavy ion collisions is deposed in the compound system and nuclear fragments and the corresponding channels of their de-excitation. By means of NAUTILUS data and from comparisons of data with simulations it is now possible to measure life-times (down to 10{sup -22} s), the nuclear flow and the form of fragment emitters. These methods will be extensively used in the analysis of data taken with INDRA, which already has made evident a vaporization threshold. A second direction of research is based on the possibility to produce by fragmentation nuclei with a very anomalous neutron and proton composition. LISE, SISSI, and SPIRAL are used to re-accelerate the exotic or radioactive ions. By utilisation of DEMON the neutron halos of several nuclei has been studied, among which the one-neutron halo in {sup 19}C. The laboratory has participated also in large collaborations (NEMO) which investigated the neutrino nature and its rest mass which are important problems related to the validity of the particle physics standard model and, in turn, to the problem of the dark matter of the universe. A significant effort was attached to the realization of the utilized detectors and associated electronics. A special neutron detector was conceived and certified for COGEMA. The help of other institutions among which IN2P3, an CNRS institute, is acknowledged. There financial support as well as that obtained through ISMRA and the university has permitted the fruitful integration of LPC Caen in large national and international collaborations

    Robert, I.; Arnould, E. [Comite Wallon de demergement, Liege (Belgium)

    2004-10-01

    As early as 1880, pumping stations have been the responsibility of coal-mining companies and local Councils. After the Meuse river caused a dramatic flooding of the valley in 1926, it was decided to put in place new techniques and methods, and a Water Elimination Committee, consisting of three experts, was created. In association with local organisations (AIDE in the Liege area, Igretec for Charleroi and IDEA in Mons-Borinage), the missions of the Water Elimination Committee were redetermined in 1987 and in 1991, with a legal definition of the water elimination works and the way that they are financed: 83% for the investments and 75% for the work expenses by the Walloon government; the remaining parts being paid by the local Councils. The author gives various examples of works in the concerned areas. In conclusion, even if the situation seems to be under control, as was the case during the last flood in 1993, new studies are required in order to better define the risks and the risk management. For the last 75 years, 500 million euros have been spent and 100 million will be spent in the future, to increase the protection of the concerned areas. It is, however, also necessary to renovate the old installations and this will cost about 600 million euros in the next 60 years, at 10 million euros per year. (authors)

    Full Text Available Dengue Haemorrhagic Fever (DHF is a major health problem in Tembalang sub district, Semarang City. Fogging with insecticide applications was done frequently as an effort to control Dengue vectors. The use of insecticides from the same class in a long time can lead to resistance in mosquitos’ population. The research aimed to observe the activity of monooxygenases in Aedes aegypti populations in Tembalang Subdistrict, Semarang. The study was conducted during February-November 2014 with a cross-sectional design in 10 villages in Tembalang Subdistirict, Semarang City. Field strains of Ae. aegypti eggs were collected using ovitraps. The collected eggs were grown under standard condition to adult mosquitoes. Mosquitos’ homogenate were stored at -85C and used for biochemical assays. The results showed there was increased monooxygenases activity in Ae. aegypti populations. Resistance to synthetic pyrethroid insecticide in Ae. aegypti mosquitoes population in Tembalang Subdistrict might be caused by the mechanism of detoxification enzymes in particular monooxygenases

    The LPC (Laboratoire de Physique Corpusculaire) dedicated the major part of its 50 years activity to the Physics of Heavy Ions research conducted at GANIL. The activity in last two years on which this report is focused refers to this domain. Of special priority was the topics of hot and /or compressed nuclear matter aiming at understanding the physics of multifragmentation.The new ionization chambers INDRA and development of control programming required special efforts. A second direction of activity was the study of exotic nuclei particularly of halo nuclei. Specific equipment like the multi-detectors of DEMON and TAPS were designed for approaching the hot nuclei. Projects based on SPIRAL beams and collaborations dedicated to investigation of different new branches of exotic radioactivity ({beta}, xn: TONNERRE project) or mechanisms of induced fusion by radioactive nuclei to produce superheavy nuclei are reported on. The LPC was implied also in two important research programs, PRACEN and GEDEON (treatment of radioactive wastes) which made clear the evolution of research for the next two years: the correct understanding of the mechanisms of light particle production in neutron induced collisions at 20 to 200 MeV. In the frame of NEMO Collaboration that approaches topics related to the weak interactions the Laboratory has developed and tested the trigger system of NEMO3. A program utilizing ion trapping on SPIRAL for efficient studies on {beta}-neutrino angular correlations in superallowed decays will be thus feasible. Contracts like COGEMA and DAMRI oriented toward applied research are also mentioned

    This report describes the activity of Linear Accelerator Laboratory at Orsay on 1996, 1997, and 1998. The physics research is focused onto three issues. The first has as objective the precise test of standard model in the sector of gauge boson interactions at LEP (ALEPH, DELPHI) and HERA (H1) and in the sector of matter properties (tau lepton, b quark, CP violation and neutrino mass). The second is a search for high energy new particles, particularly the Higgs boson and the particles predicted by supersymmetry. Finally, there is an astrophysics program aiming at gravitational wave detection and precise measurement of the relic background radiation by gravitational lensing and of high energy photon showers. The LAL plays a foremost role in the construction of the large experiments ATLAS, NEMO, VIRGO (especially mechanics) and BABAR and LHCb (electronics). The computing sector entered a new phase of critical mutations (relating to new tools and languages). Reported are also the LAL contributions to the TTF injector, the test station installed at Hamburg for the future superconductor e{sup +}e{sup -} collider TESLA and the effort in superconductor accelerator R and D of the DAPNIA-IN2P3 French collaboration. An illustration of the LAL efforts for developing applications is the electron beam project ELYSE designed for chemical utilizations, based on the experience with the photon triggered gun CANDELA.

    Full Text Available This article outlines the results on the antimicrobial action of electrochemically activated water solutions (anolyte/catholyte, produced in the anode and cathode chamber of the electrolitic cell. Under laboratory conditions the cell culture and suspensions of classical swine fever (CSF virus were treated with the anolyte. After inoculating them with cell cultures, the viral presence (the presence of viral antigen was measured using the immunoperoxidase technique. It was found that anolyte did not affect the growth of the cell culture PK-15; viral growth during the infection of a cell monolayer with a cell culture virus was affected in the greatest degree by the anolyte in 1:1 dilution and less in other dilutions; whereas the viral growth at the infection of a cell suspension with the CSF virus was affected by the anolyte in dilution 1:1 in the greatest degree, and less by other dilutions; viral growth at the infection with a virus in suspension of the cell monolayer was affected by the anolyte in all dilutions. Unexpectedly, the stronger biocidal effect of the catholyte was observed when a strain of E. coli DH5 was treated by the anolyte and catholyte, respectively. In order to provide additional data about the antiviral activity of the electrochemically activated water and the distribution of H2O molecules according to the energies of hydrogen bonds, the non-equilibrium energy spectrum (NES and differential non-equilibrium energy spectrum (DNES of the anolyte and catholyte were measured.

    The A.C.R.O. is an association law 1901 declared at the Calvados prefecture at the date of 14. october 1986 and registered as environment protection. It was created, by more than 900 persons, in the months following the Chernobylsk accident in reaction to a lack of information and means of independent radiation monitoring. The particularity of the association is to own a laboratory of radioactivity analysis. Since the end of the nineties, the concerns include the natural sources of irradiation as the radon and apply to the consequences, out of nuclear industry, of the use of ionizing radiation or radioactive matter. On this last point, the affair of the orphan industrial site Bayard at Saint-Nicolas-d'Aliermont, massively contaminated by radium-226 devoted to the fabrication of alarm clocks, and the appearance of exemption threshold in the European law are elements at the origin of this evolution.

University research laboratories and engineering schools created the Ameth network in order to share their means and competences in heat transfer research, to draw bridges between different subjects and to organize coordinated projects. In 1997 the Ameth laboratories have carried out 10 projects grouped into three themes: the thermal hydrodynamic instability and the limit boundary control, the transfers with liquid/vapor phase change and the transfers with solid/liquid phase changes. These projects and their first results are reported in this book of proceedings. This conference day was jointly organized by the thermal engineering university group (GUT) and the French society of thermal engineers. The ten communications presented in this book deal successively with: `the active control of a Poiseuille flow in the presence of volume heating`; `the control of instabilities, transition and thermo-convective flow transfers in cavities: application to the ventilation of rooms`; `the control of heat transfers during space-time flow disturbances in cylindrical channels`; `the characterization of surface heat transfers using transient methods improved for boiling in pool applications`; `the intensification of heat exchanges during boiling in confined medium`; `the evaporation and boiling in porous media`; `the characterization of heat transfers in micro-heat pipes`; `the AmETh 3-1 operation: experimental and numerical analysis of thermal resistances at the polymer-mould contact and developing during solidification`; `the analysis of solidification phenomena at the interface between a substrate and a melted medium`; and `the heat transfers with solid-liquid phase change`.

    The French law from December 30, 1991 has defined an ambitious 15 years program of researches in order to explore the different possible paths for the long-term management of long-lived high and intermediate level radioactive wastes. The law foresees also that at the end of the 15 years research program, a project of law will be prepared by the French government and transmitted to the European parliament in 2006. A public debate has been organized and emceed in 2005 in order dialogue with the general public and to gather its questions, remarks and fears. In the framework of their contribution to this debate, the ministries of industry and environment have prepared this document which answers some key questions about radioactive waste management: where do wastes come from, what are the risks, how are they managed today in France and in foreign countries, what are the results of the researches carried out during 15 years, what are the advantages and drawbacks of each waste management solution considered, what is the perspective of application of each solution, what is the position of experts, what will be the decision process. This synthetic document supplies some reference marks to better understand these different points. Some pedagogical files about radioactivity, fuel cycle, and nuclear industry activities are attached to the document. (J.S.)

    We find here the progress report for the two years 1994 and 1995 for institute of nuclear sciences at Grenoble. In the field of quarks and leptons, three teams are invested in CERN programmes: A.T.L.A.S. near the L.H.C., D.E.L.P.H.I; the neutrino team has achieved the building of the detector in the M.U.N.U. collaboration. In the theme Hadrons physics we have G.R.A.A.L. at E.S.R.F., C.E.B.A.F. and W.A.89. Physicists are implied in the project E.L.F.E at D.E.S.Y. The study of superdeformed states go on with E.U.R.O.G.R.A.M. New techniques have been used near the programme S.A.R.A. The programme P.I.A.F.E. saw the resolution of the difficult problem of the transformation 1+ gives N+ ions of 30 KeV and their transport on long distances. The team of hybrid reactors have shown that it was possible to amplify energy by a sub critical accelerator-reactor hybrid system, experience initiated by C. Rubbia at C.E.R.N. (N.C.).

    The A.C.R.O. continues to play an indispensable role through both additional objectives which guide its activities: the environmental surveillance and the public information. In 2004, these objectives are translated by numerous actions which join the continuity of the orientations taken for several years, as for example the periodic publication of all the analysis results via our quarterly review and our www.acro.eu.org web site, but also our participation at commissions, working groups and groups of institutional experts or not. Year 2004 marks the beginning of our commitment in Belarus, country still strongly marked by the disaster of Chernobylsk, to work with the population of the contaminated territories. The project aims to set up a surveillance of the contamination at the inhabitants disposal and to promote the distribution of information and knowledge in radiological protection, essentially turned to the young people, the housewives and the pregnant women. The peculiarity of this project is to give the coordination to the inhabitants, so that they can pursue it in any autonomy. On the day before the 20. anniversary of the disaster, this commitment seems to us important and meaningful as the international community seems to have forgotten Chernobylsk; beyond the help which we can bring over there, we also have many things to be learnt to pass on and testify around us. As regards the environmental surveillance, the A.C.R.O. decided in 2004 to melt again its programs of surveillance and evaluation led on the scale of the big West to form only one. Key project of year 2004, the launch of the network citizen of the wakefulness, information and radioecological evaluation (R.I.V.I.E.R.E.) allows to understand the levels and the tendencies of the aquatic ecosystems radioactivity on the scale of the Seine Normandy pond: from Nogent-sur-Seine to La Hague and from the Mont-Saint-Michel to Penly. The peculiarity of this network, which also makes its strength, is to associate strictly all those who wish to appropriate the knowledge of the radioactivity levels 'around them'. With R.I.V.I.E.R.E, the citizen is at the same moment an author and an actor of the surveillance of his environment as his information, a initiative which we defend for a long time. Finally, on the sector of the training, the itinerant operation led this year within the framework of the 'feast of the science', has allowed to introduce 800 young people of our region to the radioactivity measure in our mobile 'laboratory', but also to make sensitive the general public in the surveillance citizen of environment.

    A.C.R.O. (Association pour le Controle de la Radioactivite dans l'Ouest) is a French non governmental organisation that operates a laboratory for radioactivity analysis. It was created in 1986 as a response to people demands for information and reliable, independent testing. The organisation mainly carries out missions of information and training for its correspondents and more generally for a wide audience, particularly for people who worry about problems of environment, health, management of radioactive waste and emissions. Thanks to its structure, it enables citizens to involve themselves together with scientists so as to gain access to information that was hither to reserved to specialists. The organisation can vouchsafe its independence from the diversity of its members and volunteers, as well as from the diversity of its money resources. Besides its headquarters situated on the city of Caen area (Normandy), three branches situated in North Normandy, in Touraine and North Cotentin enable A.C.R.O. to assert its presence in the west of the French country. The association is run by a 30-plus team of volunteers and employees, structured in four committees : science, information, secretarial offices and management. Certified for the Protection of the Environment, the association was granted a technical qualification certificate for its testing and measurement activities by the French Health Authorities, according to decree n. 88 715 of May 9, 1988. In connection with all the human and technical know-how that it has links up over the years, the A.C.R.O. has developed such expertise as has made it an essential player in public debate; it has also led it to take part in numerous work groups and official committees and improve the public information through the regular publication of 'the nuclear chronicle'. Several actions are to be noticed: Radio ecological follow through of the aquatic environment both continental and marine of the sea-coast of Normandy from 2001 to 2003; Radio ecological monitoring of the environment of the Cogema la Hague building site in the Moulinets cove;Inventory of the radioactivity of the catchment area and the Brest Harbour (achieved in march 2003); Radiological measures of the earthly environment of the establishment of the G.I.P.

    This work concerns the quantitative analysis of hydrogen isotopes in of H2/D2/T2 and H20/D20/T20 mixtures. The radioactivity of tritium and its nuclear environment explain the need for distant analysis. Spontaneous Raman spectroscopy has been chosen as analytical tool because it can differentiate all the isotopic molecules we are interested in. The possibility to record spectra distantly with optical fibers makes it a good solution for the two cases we are presenting. For tritiated water analysis we have used a multi-fiber probe which penetrates the glovebox and allows to record the water spectrum through the closed glass flask which contains it. In two minutes we can detect 0.56 molar % of H20 and D20, and 0.056 molar % of 120 (1800 i/l). For gaseous hydrogen mixtures we have developed a multipass cell connected to the Raman installation with one hundred meter optical fibers. Each of the six molecular species resulting of isotopic exchanges are detected in two minutes until partial pressures of 2O mbar. (author) 80 refs.

    This thesis deals with the understanding of the spontaneous electroweak symmetry breaking mechanism in the ATLAS experiment at LHC collider, by studying two complementary topics: the search for the Higgs boson in the H {yields} {gamma}{gamma} channel, and a search for extra dimensions in the gluon sector. Tests of the electronic of the electromagnetic calorimeter allowed us to validate various cards that were under the responsibility of the LPNHE. Using full simulation data of the detector allowed us to precisely compute mass resolution of the di-photon system. Due to recent theoretical improvements, signal and background have been studied at the next order of the perturbative development, which increases cross-sections. With regards to the jet background, a study has been done using discriminating variables in order to obtain, for a 80 % photons efficiency, a rejection factor of 7000. The discovery potential benefits from this change of cross-sections and increases by 50 % in comparison with the same analysis done at the leading order. In addition to this, a new analysis using a maximum likelihood method allowed us to increase by 40 % the discovery potential in comparison with our classical analysis. In conclusion, the Higgs boson of 120 GeV/c{sup 2} can be now discovered in this channel with an integrated luminosity of 10 fb{sup -1}. Furthermore, the consistency of the problem of the Higgs boson mass can be solved by introducing extra dimensions in which gluons can propagate. We have shown that it was possible to discover extra-dimensions up to a compactification scale of 15 TeV. (author)

    Iron industry provides blast-furnace slag production as waste. Blast-furnace slag are made of non ironic elements, flux and coke ash. These elements might have binding properties such as cement. Usually, only blastfurnace slag chemical composition is considered to evaluate its quality as a binder. Other properties such as crystal phases amount, grading, specific area or temperature are not considered Some studies have shown that binding properties exist when the blast-furnace slag is quenched and crushed in very fine grains, and that an increase of the temperature has a benefit aspect on the kinetic of the reaction. We have used X ray diffraction, SEM observations with micro analysis on different samples of blast-furnace slag that undergone different cure modes. At low temperature, only non complete crystal phases appear. At room temperature, calcium sulphate and hydrated aluminium sulphate (ettringite) exist such as for Portland cement while setting. Under a steam curing mode, there is very few lime in the blast-furnace slag because lime has reacted with silicate, therefore there is much more CSH in the binder. No ettringite can be detected, on the other hand, the steam curing mode produce formation of hydrated calcium aluminate. Les laitiers de haut fourneau sont des sous produit de l'élaboration de la fonte. lis sont formés de constituants non ferreux, des fondants et des cendres de coke. Leur composition chimique laisse présager des propriétés liantes comme celles que l'on obtient avec les ciments. Les qualités hydrauliques de ces matériaux sont actuellement estimées par des calculs basés sur leur composition chimique. Elles ne tiennent pas compte d'autres paramètres tels que le caractère vitreux ou cristallin, la granulométrie ou la surface spécifique, la température entre autres. Les propriétés liantes apparaissent lorsque le laitier est trempé et broyé très finement, la température augmentant la cinétique. Les produits formés analysés par diffraction X et observés au MEB couplé à une micro analyse sont, pour des températures faibles, des phases semi cristallines. Dans les produits étuvés, la chaux est en plus faible quantité, elle a réagi avec la silice: les CSH sont en plus grande quantité. Le sulfate de calcium et d'aluminium hydraté (ettringite) apparaît à température ambiante comme dans le cas de la prise des ciments Portland mais est absente dans le ciment au laitier étuvé. A l'inverse, la formation de l'aluminate de calcium hydraté est favorisée par l'étuvage.

    Full Text Available Impacts of gravel extraction activities in Southern Benin: Residents' perception. Gravel extraction activities in Southern Benin are carried out without formal license from the state authorities. The majority of sites are rented from landowners and located near other forms of land use including human settlements. This study aims at assessing the perception by the residents of these gravel extraction operations. The results show the social services and damages of this industry. An ordinal logit regression revealed significant influences of the respondents' ethnic group, occupation, education level, marital status and age on the perception of road infrastructure, dust pollution, loss of agricultural land and school drop-out. Therefore, it is important that the local authorities undertake mitigation actions in particular in order to prevent road dust occurrence and to restore abandoned sites so that these sites are again available for agriculture.

    The new regulation in matter of radiation protection, coming from the transposition of the European directive 96/29/EURATOM modifies the code of the public health and the labour code. The exposures to natural radioactivity by the very fact of human activities are the object of specific dispositions. These new dispositions apply to professional areas that were, until now, little concerned by the regulation relative to ionizing radiations. The S.F.R.P., in relationship with the Minister in charge of labour, and the A.F.T.I.M. (French organisation of safety technicians and engineers and labour physicians) organizes two days of information and exchange on the subject. This meeting concerns industry and research departments but also inspectors and labour physicians and other actors having a look on the risk management in societies. After some reminder on radioactivity and its effects, the regulation and the global risk management on working place, several actual examples are presented, covering the different known situations of exposure to the natural radioactivity ( radon, cosmic rays, use of radioactive material in an industrial process, production of radioactive waste). The days finish by a round table conference on the stakes and practical entailment of the new regulation. (N.C.)

    Our work aims to study tools offered to students and tutors involved in face-to-face or blended project- based learning activities. Project-based learning is often applied in the case of complex learning (i.e. which aims at mak- ing learners acquire various linked skills or develop their behaviours). In comparison to traditional learning, this type of learning relies on co-development, collective responsibility and co-operation. Learners are the principal actors of their learning. These trainings rest on rich and complex organizations, particularly for tutors, and it is difficult to apply inno- vative educational strategies. Our aim, in a bottom-up approach, is (1) to observe, according to Knowledge Management methods, a course characterized by these three criteria. The observed course concerns project management learning.

    In the eighties photographs from cloud chambers where used in the French physics curriculum of grammar schools to study particle collisions inside a magnetic field. This was a simple but efficient means to illustrate elastic and non-elastic collisions and energy and momentum conservation laws. The teachers used transparent abacus to determine the radius of curvature from which particle's linear momentum was deduced. Now photographs have been digitized and a software has been created to determine the value of the radius by simple mouse click. This pedagogical tool has become easier to use and remains a very interesting means to make students touch concrete and surprising physics. (A.C.)

    To improve anaerobic digestion of pig manure, solubilization of the solid fraction was studied as the rate limiting step in the biomethanation process in an experimental completely mixed digester. The performance of conventional digesters should anaerobic microflora were inefficient in degrading complex biopolymers such as plant fibers. For pectin or cellulose, the use of digestible co-substrates accelerated methanation by increasing the yield of methane and a doubling of the apparent first order solubilization rate constant (Kp = 0.090/d). Lignin should methanation by decreasing methane yield and reducing the rate constant (Kp = 0.035/d). This inhibition was unrelated to volatile fatty acid accumulation. Nine strains of pectinolytic and/or cellulolytic bacteria were isolated. Chitin, a structural constituent of many final species, was effectively solubilized dining anaerobic digestion of pig manure. Seven strains of chitinolytic bacteria were isolated by high chitnese activity. The mycolytic power of fermenting manure processes acting through lytic microflora has been shown to be an effective antagonist of soil borne phytopathogenic fungi, as well as a fertilizer. In greenhouse trails, this compiled fraction demonstrated its ability to control flux unit. Keratin enhanced methane production, and increased H{sub 2}S nearly six-fold. Bacterial strains able to solubilize keratin were also used in autoclawed feather meal to extract the amino acids. (KJD)

    Full Text Available Abundance and Distribution of Great Apes and Human Activities in the Campo Ma'an National Park, South Cameroon. The Campo Ma'an National Park (CMNP located in South Cameroon, has a rich biodiversity and is part of the priority areas of the Central Africa Network of Protected Areas. In order to improve the knowledge on great apes in this park, an inventory was conducted between October and November 2011 using the linear transect technique. In total, 103 transects, 2.5 km each, were established and surveyed. The results of the study confirm the presence of the two species of great apes in the CMNP, chimpanzees (Pan troglodytes troglodytes and gorillas (Gorilla gorilla gorilla. The inventory suggested that chimpanzees had a nest density of 0.158 nest∙km-2, allowing an estimated density of 0.555 indiv.km-2, for a total population estimated at 1466 animals weaned throughout the Park. Chimpanzees were mainly located in the northern part of the Park, near the hilly area of Niété. Gorillas had an estimated average encounter rate of 1.080 sign per km. They also appeared to be more concentrated around the area of Niété. Poaching was the preferred type of human activity in the Park and was located in the northern part of the Park. It is strongly recommended to implement the results of this study by performing regular surveys, about every 3 months, in order to monitor the demography of the great apes populations in the Park.

    Measurements of superficial tension of n-alkyltrimethylammonium bromides in air/water-orthophosphoric acid interface have been made by “stripping method". Data were evaluated by approximation to the Von Szyszkowski equation. Thermodynamic parameters as (Γmax, F, A, B, Δ G^circ_A, Δ GM and CMC) at different concentrations of orhophosphoric acid (0 at 3 M) are calculted. The CMC values of the homologous series in relation to the chain length were determined. They showed a good correlation with the Klevens equation. A minimum of CMC and (-ΔGM) was observed for the n-octadecyltrimethylammonium bromide, which has been attributed to the cosolvant effect and the change of medium properties. L'adsorption, de bromure de n-alkyltriméthylammonium à l'interface air/eau-acide orthophosphorique, a été étudiée par la mesure de tension superficielle en fonction du nombre d'atomes de carbone du groupement alkyle et de la concentration en acide orthophosphorique (0 à 3 M). L'analyse des résultats a été effectuée à l'aide de l'équation de Von Szyszkowski. Les grandeurs et paramètres thermodynamiques (Γmax, F, A, B, Δ G^circ_A, Δ GM and CMC) ont été déterminés et discutés selon l'équilibre de forces de répulsion électrostatique entre les têtes polaires et d'attraction hydrophobe des chaînes aliphatiques. Les valeurs des CMC obéissent à l'équation de Klevens. Dans le cas du bromure de n-octadécyltriméthylammonium les valeurs de la CMC et de (-ΔGM) présentent un minimum, attribué au changement des propriétés du binaire eau-acide orthophosphorique.

    The Global Partnership Against the Spread of Weapons and Materials of Mass Destruction was launched by the heads of state and government of the G8 at the G8 summit in Kananaskis in June 2002. Fourteen other countries have since joined this G8 initiative. The aim of this partnership is to 'prevent terrorists, or those who harbor them, from acquiring or developing nuclear, chemical radiological and biological weapons, missiles, and related materials, equipment and technology'. Within the framework of the Partnership, the participants have agreed to support cooperation projects, starting with Russia, to promote non-proliferation, disarmament, the fight against terrorism and nuclear safety. The destruction of chemical weapons, the dismantling of decommissioned nuclear submarines, the disposal of fissile materials and the employment of former weapons scientists are among the priority concerns expressed. Ukraine has also been a beneficiary of this partnership since 2004. The participants in this initiative have agreed to contribute up to 20 billion dollars (up to 750 million euros from France) to support these projects over a period of ten years from 2002. A group of experts from the G8 on the Global Partnership (the GPWG = Global Partnership Working Group) meets regularly and gives an account of the progress made with this initiative in its annual report to the G8. These annual reports are published at the G8 summits. This document is the 2004 to 2006 activity report of the G8 global partnership.

    Full Text Available The communication activity, in its most diverse forms, is an important component of public administration activities, having an instrumental value related to the activities of public administration. The success in achieving objectives by public authorities depends, in part, on the efficiency of communication undertakings, which are differently addressed by the authorities in the context in which the law only includes generic obligations to this end. Thus, communication practices are being developed at institutional level, which reflects the level of awareness of public authorities with regard to the functions of communication and the need to communicate, especially with their public.

    The international traceability of antimony 124, in term of activity, is very limited. The results of {sup 124}Sb activity measurements sent to the SIR (BIPM - International System of Reference, BIPM.RI(II)-K1.Sb-124.) are scarce. Up to now, only three laboratories have contributed. Two of them carried out measurements using the 4pibeta-gamma coincidence counting technique and the third one using the 4pigamma method with a well-type crystal detector. The first two results are in agreement but the last one differs significantly from them, by 2 %. The decay scheme consistency cannot be excluded when trying to explain those discrepancies. In other respects, this nuclide emits high-energy gamma rays, and then could be selected as a valuable standard radionuclide for the calibration of gamma-ray detectors in that energy range, given well known photon intensities. Those considerations led to the proposal of an international exercise and to the realisation of this Euromet project, registered as project no. 907, coordinated by CEA-List-LNE/LNHB. The first part of this exercise was dedicated to activity measurements and to their comparison. For this purpose, participants were asked to make use of all the direct measurement techniques available in their laboratory in order to confirm or not the existence of possible biases specific to some measuring methods. In addition, this exercise offered the opportunity of improving the uncertainties of the gamma-ray intensities. Then, participants were asked, in the second part of the exercise, to carry out X-ray and gamma-ray intensity measurements. These results have been compared to previous published values and new decay scheme data are proposed. Eight international laboratories participated in this exercise. (authors)

    Classically, radiation injuries results in a peripheral inflammatory process, and we have previously observed an early systemic interleukin 6 (IL-6) release following whole-body irradiation. Besides, we have demonstrated an early decrease of rat or primate brain acetylcholinesterase (AChE) activity a gamma exposure. The object of the present study is to find possible IL-6 systemic effects on the brain AChE activity. We show that, though intravenous (i.v.) or intra-cerebro-ventricular (ICV) injection of IL-6 can induce a drop in rat brain AChE activity, this cytokine induces only a slight decrease of the AChE release in cultured brain cells.

    2007-12-15

    A national survey was made at the 2008 la Baule Symposium 'nuclear medicine facing major public health challenges'. The aim was to evaluate the activity in the fields of clinical specialities involved in these challenges : cancerology, cardiology and neurology. The response rate was 62%. The total number of PET scans performed in France during the year 2007 was about 100,000 including 97.5% of cancer indications. The mean number of PET scans per center was 1285, with a maximum of 3500 scans. The first indications were lung cancer (27%), lymphoma (20%) and colorectal cancer (14%). The registered number of cardiac examinations was 170,387 extrapolated to a total number of about 250,000 examinations in one year. The number of registered brain SPECT was 11,215 corresponding to about 100 examinations per center in one year. The survey pointed out large variations of PET activity between centers and suggested potentialities in extending and diversifying the field of PET. Brain scintigraphy appeared as a minor sector out of proportion with the challenge of degenerative brain pathology. Performing again these evaluations in the next years should allow to better describe the capabilities of nuclear medicine to face the major challenges and the evolution of public health.

    Full Text Available MINSHALL et KUEHNE ont signalé que, dans la « Région des lacs » en Angleterre, alors que la faune typique d'un ruisseau à fond pierreux peut monter jusqu'aux sources dans les montagnes, il y a des zones où la faune est pauvre, hormis les Plécoptères. Dans ces dernières eaux, le pH et le taux en calcium sont faibles, comme l'ont montré SUTCLIFFE et CARRICK qui pensent qu'il s'agit d'une pollution atmosphérique. De telles communautés habitent les affluents de la Rivière Lune. La rivière elle-même traverse une gorge où, grâce aux éboulis, le fond est stable. La faune actuelle est riche en espèces et en individus, surtout en larves de Tricoptères avec filet. C'est presque la seule région où les mollusques ne risquent pas d'être écrasés par les pierres roulantes. En aval, dans une longue plaine alluviale, le substrat est instable et, en conséquence, les espèces sont peu nombreuses bien que les individus de quelques-unes soient abondants. Une augmentation de l'enrichissement actuel provenant des villes et des prairies cultivées pourrait provoquer une croissance excessive des algues filamenteuses. Celles-ci font disparaître la vraie faune lithicole et disparaissent elles-mêmes en temps de crue, en emportant vers l'aval les animaux qu'elles hébergent. Au-delà de la plaine, la rivière traverse une région à pierre meulière, sur un lit plat et lisse. Entre deux barrages, ce lit est couvert de mousses habitées par 4 espèces d'éphémères qui ne se trouvent ailleurs, que dans de petites baies où le courant est faible. On a remarqué dans une rivière voisine la disparition de telles espèces après l'amélioration du lit par les ingénieurs.

The chemical composition of the essential oils obtained by hydrodistillation of dry leaves from Cymbopogon citrates (DC. Stapf, Ocimum canum Sims, Ocimum gratissimum L. var 'gratissimum' L. and Thymus vulgaris L. cultivated in Cameroon were analyzed and their larvicidal activity against fourth instar larvae of Anopheles gambiae Giles were determined. The yields of extraction indicate that T. vulgaris (0.95% was richer in essential oil than C. citratus (0.67%. O. canum and O. gratissimum have approximately the same content in volatile constituents (0.59% and 0.60%, respectively. The analyses by GC and GC/MS showed that these oils are monoterpenic (86.8-97.4%. Oxygenated monoterpenes predominate in C. citratus and O. canum (81.6% and 68.9%, respectively while O. gratissimum oil contains a majority of monoterpene hydrocarbons (61.0%. T. vulgaris is characterized by the same proportion of monoterpene hydrocarbons (45.6% and oxygenated monoterpenes (48.9%. The main compounds found in the essential oil of C. citratus are acyclic monoterpenes such as geraniol (15.6%, geranial (39.3%, neral (21.9% and myrcene (14.0%. The essential oil of T. vulgaris is characterized by p-menthane structures given by thymol (40.1%, p-cymene (23.4% and γ-terpinene (15.1%; p-cymene (32.1% and thymol (24.3% were also the constituents quantitatively important in O. gratissimum essential oil while linalool (56.3% and limonene (10.9% were predominant in O. canum. Bioassay test done by the World Health Organization standard protocol revealed that these essential oils have remarkable larvicidal properties as they could induce 100% mortality in the larvae of A. gambiae at the concentration of 100 ppm for C. citratus, 200 ppm with T. vulgaris, 350 ppm for O. gratissimum and 400 ppm for O. canum. Their LC50 and LC80 show the same reactivity order. The essential oil of C. citratus was found to be the most efficient, with respective values of: LC50 = 18 ppm and LC80 = 25 ppm.

    The law from December 30, 1991, precisely defines 3 axes of researches for the management of high level and long-lived radioactive wastes: separation/transmutation, surface storage and underground disposal. A global evaluation report about these researches is to be supplied in 2006 by the French government to the Parliament. A first synthesis of the knowledge gained after 14 years of research has led the national commission of the public debate (CNDP) to organize a national debate about the general options of management of high-level and long-lived radioactive wastes before the 2006 date line. The debate comprised 4 public hearings (September 2005: Bar-le-Duc, Saint-Dizier, Pont-du-Gard, Cherbourg), 12 round-tables (October and November 2005: Paris, Joinville, Caen, Nancy, Marseille), a synthesis meeting (December 2005, Dunkerque) and a closing meeting (January 2006, Lyon). This document is a summary of the main questions tackled during this debate from its preparation to its closing meeting and dealing with: the acceptation of the debate, the progress of the debate, the socio-technical problem of gathering the different points to be debated with respect to the different areas in concern, the general questions about the overall nuclear wastes and materials (radioactivity, health, radioprotection, management, reprocessing, control, actors organization, knowledge sharing, perenniality of the financing), the specific questions about long-lived wastes (inventory, separation-transmutation feasibility, nuclear energy and energy policy, management solutions, storage and geologic disposal feasibility, impact of debates on the 2006 law, long-lived waste territories), the conclusions for the 2006 law: mastering the overall nuclear wastes and materials and step-by-step building up of a solution for long-lived wastes (difficulties, lessons learnt from foreign experience, first draft of the 2006 law). Some opinions expressed by some participants about these proposals conclude the document. (J.S.)

This document is a status of the general organisation and progress of the debate from its preparing to its end in mid-January 2006. It shows the challenges the CNDP had to take up to treat the scientifical and technical questions in an accessible way, allowing the participation and the hearing of the large public. A status is made of the deception and satisfaction of the public. A lack of confidence in public authorities and scientists has been expressed several times. No pro-nuclear/anti-nuclear shock has occurred and the debate has revealed a remarkable richness in its content. One contribution of the debate to the future project of law is its enlargement to the overall nuclear wastes and valorizable materials and not only to the high/intermediate-level and long-lived wastes.

    In tokamaks such as Tore Supra, the plasma confinement magnetic structure can be severely affected when Magnetohydrodynamic (M.H.D.) instabilities are destabilized. Experimentally, these instabilities are detected as magnetic fluctuations with captors located against the inner wall of the vacuum vessel. Fourier analysis provides amplitude, frequency and wave numbers of magnetic modes. In case of fast or transient phenomena, the analysis of magnetic fluctuations is completed using the singular value decomposition. In this dissertation, these analysis techniques are used to study two specific examples of M.H.D. activity related to the m = 2, n = 1 mode. On Tore Supra, the onset of this mode have strong consequences on the stability of partially or fully non inductive discharges. A regular and persistent sawtooth-like regime is observed on the electronic temperature leading to a significant degradation of the central confinement. Heat exhaust and particle balance are also essential parameters to achieve stationary discharges. On Tore Supra, these are studied with the ergodic divertor which produces stochastic magnetic field lines at the plasma edge. For optimal operating conditions of the ergodic divertor, the growth of the m = 2, N = 1 mode can lead to sudden destruction of magnetic equilibrium. For both cases, understanding and characterization of mechanisms leading to the observed m = 2, n = 1 M.H.D. activity are fundamental to obtain stationary discharges. (author). 115 refs.

    Full Text Available Lorsqu’une catastrophe humanitaire fait la une des médias, la communauté internationale se mobilise à réduire les conséquences les plus sérieuses. La population du Tchad connaît cependant des crises endémiques qui ne sont liées à aucun élément déclencheur particulier# ; elle ne reçoit pas l’assistance internationale nécessaire pour faire face à ces problèmes. La présente étude concerne 111 ménages de migrants de la région du centre du Tchad, qui ont, à cause de la guerre et de la sécheresse, tout perdu, et qui vivent désormais dans de N’Djamena et de Mongo#; ces familles sont confrontées à la précarité et à d’autres éléments qui menacent leurs moyens de subsistance. Des méthodes qualitatives et quantitatives ont été combinées dans l’étude pour révéler l’histoire intrigante de leur vie quotidienne au milieu de crises complexes et endémiques. Des données anthropométriques et sanitaires ont été utilisées pour déterminer l’état nutritionnel des mères et de leurs enfants de moins de cinq ans. Des narrations de vie, des entretiens en profondeur et des observations participatives ont permis aux chercheurs de déterminer les stratégies de négociation que ces familles adoptent pour accéder à leur nourriture et à leurs abris, leur expérience de l’insécurité alimentaire et de la vulnérabilité sanitaire, ainsi que les conséquences que ces éléments ont sur leur vie quotidienne. Les résultats indiquent que 62% des ménages sont dirigés par des femmes, qu’il existe de forts taux de malnutrition aiguë (40-50% et chronique (35-40% et que 46% des mères sont sous-alimentées et anémiées. Les taux de mortalité infantile se sont avérés également élevés#: de 30% à 42%. 97% des enfants n’ont pas été complètement vaccinés, voire pas vaccinés du tout, dans certains cas. Aucun des ménages n’a accès à l’eau potable et aux services sociaux de base. La corruption endémique et l’abus manifesté par les autorités tchadiennes ont été identi$és comme sources d’insécurité quotidienne. Ces migrants considèrent cette situation misérable comme normale.

    NATURAL SCIENCES IN KINDERGARTEN: A SOCIO-COGNITIVE FRAMEWORK FOR LEARNING AND TEACHING - The present study presents a socio-cognitive framework for the construction of the scientific knowledge of natural phenomena among pre-school children and for the development of science activities at kindergarten. It involves elements from theories of social interaction; social psychology of development and cognitive functioning; and research in natural-science teaching methods which acknowledge the importance and fundamental role of social interaction in the development of cognitive operations and learning. The study also presents some of the more significant results of the research carried out on different aspects of this topic. The discussion unfolded here supports the hypothesis that the construction of natural-scientific knowledge at the pre-school age and corresponding scholastic activities are necessary and effective.

    After the diachronic cartographic analysis of Marin Bay (Martinique), the conceptors discovered a quick progradation of the shore in the bay. Measurements of erodibility were taken on the square metre scale, in different vegetal covers then extrapolated to the watershed scale. It appears that cultivated areas mostly intensively release the biggest contents of soil particles. But bathymetric and current aspects do not aid the evacuation of these particles when they settle in the bay. One can conclude that the transformations of the natural landscape (accretion of coasts) are linked with the transformations of soil occupation modes.

    In red blood cells, a modulation of the level of the allosteric effector of hemoglobin, 2,3-diphosphoglycerate (2,3-DPG) would have implications in the treatment of ischemia and sickle cell anemia. Its concentrations is determined by the relative activities of the synthase and phosphatase reactions of the multifunctional bis-phosphoglycerate mutase (BPGM). In this report we develop first a more direct synthase assay which uses glyceraldehyde phosphate to suppress the aldolase and triose phosphate isomerase reactions. Secondly we propose a radioactive phosphatase assay coupled to chromatographic separation and identification of the reaction products by paper electrophoresis. Such identification of these products allows us to show that the multifunctional BPGM expresses its mutase instead of its phosphatase activity in conditions of competition between the 3-phosphoglycerate and the 2-phospho-glycolate activator in the phosphatase reaction. These two more precise procedures could be used to study the effects of substrate and cofactor analogues regarding potential therapeutic approaches and could be used for clinical analyses to detect deficiency of BPGM.

    In complex industrial process control, causal reasoning appears as a major component in operators` cognitive tasks. It is tightly linked to diagnosis, prediction of normal and failure states, and explanation. This work provides a detailed review of literature in causal reasoning. A synthesis is proposed as a model of causal reasoning in process control. This model integrates distinct approaches in Cognitive Science: especially qualitative physics, Bayesian networks, knowledge-based systems, and cognitive psychology. Our model defines a framework for the analysis of causal human errors in simulated naval nuclear power plant fault management. Through the methodological framework of critical incident analysis we define a classification of errors and difficulties linked to causal reasoning. This classification is based on shallow characteristics of causal reasoning. As an origin of these errors, more elementary component activities in causal reasoning are identified. The applications cover the field of functional specification for man-machine interfaces, operators support systems design as well as nuclear safety. In addition of this study, we integrate the model of causal reasoning in a model of cognitive task in process control. (authors). 106 refs., 49 figs., 8 tabs.

    Synopsis Two thirds of the population suffer more or less severely from dandruff, a dermatological disease associated with the yeast Pityrosporum ovale. This paper demonstrates the anti-fungal activity of two substances commonly used in hair cosmetics: zinc pyrithione and piroctone olamine, at several concentrations. Based on an optimum concentration, two shampoos were formulated in order to determine the cutaneous tolerance of the finished cosmetics. A profilometry study was carried out using negative impressions obtained from skin prints to calculate the cutaneous tolerance. This study revealed the superiority of the piroctone olamine as an anti-fungal substance and its cutaneous tolerance was also better. PMID:19250498

    Full Text Available The gatering activity of wild bees (Hymenoptera Apoidea on flowers of maize at Yaound (Cameroon and further considerations on pollination of the tropical Gramineae. At Nkolbisson (Yaounde, Cameroon, in May 1991, flowers of maize (Zea mays L; Poaceae were observed for the study of pollen gathering by five different species of wild bees: one Apidae Meliponinae (Dactylurina staudingeri and four Halictidae Nomiinae (Lipotriches andrei, Lipotriches langi, Lipotriches notabilis and Leuconomia granulata. Each of these Apoidea is well attracted by pollen of maize. The larger number of bees foraging at the same time on a panicle varies from one with Dactylurina staudingeri to four with Lipotriches andrei and Lipotriches notabilis. Generally, bees forage maize during the whole day and during the full flowering period but visits are more numerous in the morning and during the period of intense flowering. Median duration of a visit on a male spikelet varies from 1 sec with Dactylurina staudingeri to 7 sec with Lipotriches andrei. These Apoidea have an elaborated behaviour when gathering pollen of maize. Dactylurina staudingeri however seems less adapted to the floral morphology of Poaceae comparing with Lipotriches. When foraging maize, all these bees are regular visitors to flowers of this plant, even in the presence of other flower species in the vicinity of the crop. Bees studied have a positive impact on the yield of grains due to a complementary action with the well known one of the wind. The influence is indirect as the bees are seldom visiting the stigmates. The explanation is that when the bees are very common on the panicles they shake the anthers, inducing the release of pollen grains in the atmosphere even in the days without wind. The part of wild bees in the increase of yields is estimated to 3/ while the one of the domestic bees (Apis mellifera is estimated to 21/ in that locality. The authors are reviewing existing literature on grass crop pollination and on Poaceae in general by various species of bees. For a better integrated crop management of maize in Cameroon, it is suggested to conserve the nesting sites of Lipotriches in surrounding areas of crops and to avoid unjustified use of pesticides during the flowering period.

Como bioindicadores, utilizou-se a respiração microbiana, quantificando a emissão de CO2 aos 2, 4, 8, 12, 16, 20 e 24 dias após incubação, a atividade da enzima desidrogenase e a hidrólise de diacetato de fluoresceína (FDA, aos 8 e 28 dias. Bentazon e a mistura de imazethapyr+lactofen na maior concentração e o haloxyfop-methyl nas duas concentrações apresentaram efeitos inibitórios na respiração edáfica, embora diferentes em época e duração do efeito. Nenhum dos tratamentos herbicidas afetou a hidrólise da FDA. A atividade da desidrogenase foi inibida, o que foi verificado em análise realizada aos oito dias,nas amostras de solo com alta concentração de bentazon e imazethapyr; no entanto, foi estimulada nos tratamentos com baixa concentração de metolachlor e imazethapyr e na maior concentração de glyphosate. A respiração basal e a atividade da desidrogenase mostraram maior sensibilidade na detecção de efeitos dos herbicidas sobre a microbiota do solo que as determinações da hidrólise de FDA. Apenas foi encontrada correlação significativa entre a atividade da desidrogenase e a respiração basal aos oito dias de incubação. Os resultados destacam a importância da consideração de múltiplos indicadores na avaliação dos efeitos de herbicidas na microbiota do solo.Effects of bentazon, metolachlor, trifluralin, imazethapyr, imazethapyr+lactofen, haloxyfop-methyl, glyphosate and chlorimuron-ethyl at rates of 2 and 10 times the equivalent commercial dose on soil microbial activity was evaluated in soil samples extracted from a field never treated before. Global soil microbe respiration, estimated by CO2 production at 2, 4, 8, 12, 16, 20, 24 and 28 days of soil incubation and enzymatic activities (dehydrogenase and fluorescein diacetate hydrolysis at 8 and 28 days were used as bioindicators. Bentazon and mixture imazethapyr+lactofen at the highest rate and haloxyfop-methyl at both rates, inhibited soil respiration although with differences in timing and duration. None of the herbicides affected FDA hydrolysis. Dehydrogenase activity was inhibited at 8 days of incubation with bentazon and imazethapyr at high rates but it was stimulated by metolachlor and imazethapyr at low rate and glyphosate at the highest rate. Herbicide effects on soil microbial activity was detected with higher sensitivity by global soil microbe respiration and dehydrogenase activity than by FDA hydrolysis. Only dehydrogenase activity and soil respiration estimations at 8 days of soil incubation had significant correlation. Results indicated the need of multiple estimations when evaluating herbicides effects on soil microbiota

These new datings in connection with a detailed stratigraphic study in the deep canyons around the volcanoes has revealed an exceptional recurrence of flank destabilizations of the Fuego de Colima during the last 45000 years. The cumulated volume of debris in the whole Colima massif is estimated to 60-100 km{sup 3}. The correlation between Landsat satellite pictures and the distribution and age of the debris flows shows that both volcanoes are made of several post-destabilization remaining structures, and that both volcanoes were active and simultaneously collapsed 18500 years ago. The numerous fluvial-lacustrine sequences intercalated between the successive flows indicate that the debris flow were partially sedimented under water and could have led to catastrophic tsunamis towards the Pacific coast. Implications of this work are important because a population of more than 200000 inhabitants is living in a zone covered by several debris flows. (J.S.).

Il apparaît que l'amplitude et la fréquence des mouvements sont le plus élevées d'octobre à décembre, pendant la période de reproduction. Les migrations vers l'amont (max. : 25 km ont principalement lieu en octobre et pendant la première quinzaine de novembre et sont déclenchées par des variations combinées du niveau d'eau et de la température, dans une gamme thermique précise (10°C à 14°C. Le frai (de la deuxième quinzaine de novembre à la fin décembre a lieu dans le cours principal (largeur maximale : 10 m ou dans de petits affluents. Les truites qui survivent effectuent un homing post-reproducteur rapide (max. : 9 200 m en 24 h et précis. En dehors du contexte de la reproduction, les déplacements sont moins longs et correspondent essentiellement à des changements alternés de gîtes dans un domaine vital bien défini dont la longueur est corrélée avec la taille des truites. En mars et juin, certaines truites effectuent des migrations unidirectionnelles de grande amplitude vers l'amont dont la signification biologique est inconnue. Les résultats sont discutés dans le contexte des stratégies de vie de la truite et de la gestion des populations.

    The p53 tumour suppressor protein has a highly complex pattern of regulation at transcriptional and posttranslationallevels. The discovery of p53 isoforms has added another layer of complexity to the mechanisms thatregulate p53 functions. Indeed, p53 is expressed as 12 isoforms that differ in their N- and C-terminus due toalternative splicing, promoter or codon initiation usage. So far, there is limited understanding of the patterns ofexpression and of the functions of each of these isoforms....

    2001-12-01

    During the 20th century, the mean temperature of the air at the ground level has increased by 0.6±0.2 °C and the warmest air temperatures occurred after 1980. These were significantly warmer than those of the last millennium. Simultaneously, rain and drought, cold and heat wave frequencies have changed, mountain glaciers retreated and the sea-level increased by ˜10 cm. This warming was at least in part induced by human activities and will continue during the next decades. Its amplitude will depend on the rate of greenhouse gas and sulphate aerosols emissions, i.e. on energetic scenarios. Pending scientific uncertainties include cloud variations and interactions between the physical parts of the climate system and the biogeochemical cycles and the biosphere.

    At the present time, a great effort of research is made on the identification and the design of enzymes insensitive or low sensitive to O{sub 2}. In parallel, it seems important to understand the inhibition mechanisms in order to propose mutations able to limit this inhibition. The Protein Film Voltametry allows to obtain data which can not be observed or quantitatively obtained by other techniques. The enzyme is immobilized directly on the electrode and the electronic transfer is direct. The redox state of the enzyme depends on the potential of the electrode and the catalytic current is proportional to the enzyme activity. The data obtained for the Ni-Fe hydrogenase (Desulfovibrio fructosovorans) and for the Fe hydrogenase (Clostridium Acetobutylicum) will be compared to the data obtained for hydrogenases of other organisms, by Protein Film Voltametry as well as by other techniques.

    In this report by the research, development and demonstration (RD+D) programme coordinators the objectives, activities and main results in the area of solar heating and heat storage in Switzerland are presented for 2003. In a stagnating market environment the strategy of the Swiss Federal Office of Energy mainly consists in improving the quality and durability of solar collectors and materials, optimizing combisystems for space heating and domestic hot water preparation, searching for storage systems with a higher energy storage density than in the case of sensible heat storage in water, developing coloured solar collectors for more architectonic freedom, and finalizing a seasonal heat storage project for 100 dwellings to demonstrate the feasibility of solar fractions larger than 50% in apartment houses. Support was granted to the Swiss Testing Facility SPF in Rapperswil as in previous years; SPF was the first European testing institute to perform solar collector labeling according to the new rules of the 'Solar Keymark', introduced in cooperation with the European Committee for Standardization CEN. Several 2003 projects were conducted within the framework of the Solar Heating and Cooling Programme of the International Energy Agency IEA. Computerized simulation tools were improved. With the aim of jointly producing high-temperature heat and electric power a solar installation including a concentrating collector and a thermodynamic machine based on a Rankine cycle is still being developed. Seasonal underground heat storage was studied in detail by means of a validated computer simulation programme. Design guidelines were obtained for such a storage used in the summer time for cooling and in the winter time for space heating via a heat pump: depending on the ratio 'summer cooling / winter heating', cooling requires a cooling machine, or direct cooling without such a machine is possible. The report ends up with the list of all supported RD+D projects.

    Among the body's defence mechanisms, the programmed cellular death or apoptosis is an important safeguard way which allows the body to get rid of the injured cells before they acquire steady genetic modifications leading to an anarchistic multiplication. As p53 tumor suppressor gene plays a predominant role within this process, this research report first presents the p53 protein, its structure, its activities as a transcription factor, its modifications and the implications on its functional activities, its biological activities, and describes the p53 intracellular rate regulation and the use of this protein in radiology, particularly in 'in vivo' investigations on irradiated mice. It also presents the p53 family. Then, the author reports experimental investigations on possible other genes which could be trans-activated by p53. A gene is identified as a new target gene. She also demonstrates a new p53 activation path induced by another member of the p53 family, the p73 alpha protein.

    In the general framework of the safety of nuclear wastes of low and intermediate activity, we studied the effects of organic compounds on the solubilization of metallic cations. Organic compounds originate from the degradation of cellulose in concrete interstitial waters. Degradation reactions generate a number of products, among which carboxylic acids. These acids are known for their chelating properties. We first analysed the degradation of cellulose in alkaline conditions: we qualitatively and quantitatively determined the degradation products for various reaction progress indices, including a dozen of carboxylic acids. The principal goal of our work was the prediction of the behaviour of metallic cations in such cellulose degradation solutions. Owing the complexity of the system, a priori theoretical calculation are not possible. We have thus decided to choose tetra hydroxy pentanoic acid as a reference compound in order to simulate as accurately as possible the behaviour of more complex acids which contain similar functional groups. We have experimentally determined the complexing properties of this reference acid toward divalent cobalt and copper, and trivalent samarium and europium. Simple and mixed complex (hydroxyl) have been evidenced in alkaline medium. Their stability constants have been determined and extrapolated at zero ionic strength using the SIT theory. These results allowed us to theoretically predict the behaviour of our four reference cations in cellulose degradation products formed in concrete interstitial waters. In parallel, we have measured their solubility in real cellulose degradation solutions. Solubility predictions are correct for transition metals, but not for rare earth cations. In this case the complexes which have been identified with tetra hydroxy pentanoic acid are not stable enough to dissolve metallic hydroxides. In real degradation solutions, other compounds would account for the enhancement of rare earth elements solubility.

    Full Text Available Research and Comparative Study of Proteasic Activities of Neutral Castes of Termite Macrotermes subhyalinus (Termitidae, Macrotermitinae and its Symbiotic Fungus Termitomyces sp. Crude extracts from neutral castes of the termite Macrotermes subhyalinus, its symbiotic fungus Termitomyces sp. and its comb are not able to hydrolyze acyl-pNA tested on acid medium. However, these substrates on alkaline medium are hydrolysed, indicating that these enzymatic sources possess proteolytic activities. Hydrolyzed acyl-pNA are Gly-pNA, LeupNA, Met-pNA, Phe-pNA, Pro-pNA, Lys-pNA, ArgpNA and Asp-pNA. The highest proteolytic activities were obtained with Leu-pNA and BA-pNA with a Macrotermes subhyalinus termite worker. It is therefore more active than the soldier. Proteolytic activities were higher in small soldiers than in large ones. The proteolytic activities of the fungus are higher than those of the fungus comb, its growth backbone. Mutal competition studies among the best hydrolysed substrates by symbiotic fungus and worker have shown that trypsic activities (Arg-pNA, Lys-pNA and BA-pNA are derived from the same enzyme. This enzymatic reaction has also been observed with Leu-pNA, MetpNA and Ala-pNA.

    The purpose of this work is to analyze the concept of competitiveness of companies and nations in the upstream sector of the international oil industry, trying to identify the possibilities of future development of this sector as well as the interactions that may exist between different actors such as governments, consumers and oil companies to boost or re-launch the competitive position of their enterprises and countries in the international context of the industry. In order to attain that, we analyze the developments of the most important economic attributes that characterize the oil activity as well as its most crucial political aspects. We develop a model of `oil competition` and a definition of `oil competitiveness` that take clearly into consideration both the differences between various oil actors and the dynamic aspects linked to the evolution of the oil industry. We do so by constructing an evolutionist model of competition and competitiveness. This approach emulates a `biological process` where firms and the economic environment interact with each other within a process similar to `natural selection` with the survival of the fittest. This evolutionist model adopts some analytical instruments established by Michael Porter, from the University of Harvard, to interpret the changes and the dissimilarities of behavior of various oil actors as well as to explain their respective role in the new oil world that is being organized. Thus, we introduce the notions of `dominant form of competition` and `generic strategy of enterprises`. Then, we use our methodology to analyze the past of the oil industry (the stability and the instability). We conclude this work by discussing about the future evolution of the oil activities in the context of a new long term cycle of investment for the sector. (author).

For this reason, the search for green fertilizers and the assessment of the behaviour and fate of organic pollutants in soil have become major research topics. It was in this regard that the present work was undertaken. I...

    According to the estimations of the report more than 450 transport of materials including about 40 tons of plutonium circulate in France during one year. The nuclear matters transported are a source of danger. The risks in relation with the handling and transport of plutonium touch the criticality risk, its great toxicity, and the problem of proliferation. To these risks it is necessary to add terrorists attacks. Three scenarios of accidents have been developed to illustrate the risk potential. A scenario of train accident, with derailment in a tunnel then crash with an other train; a simple scenario occurring to a lorry of plutonium powder; then a scenario of an accident following a terrorist act. These scenarios should be studied by I.R.S.N and the results should be given to the public and to elected people confronted to the transport of plutonium. (N.C.)

    Following the recent stratigraphic works carried out on the Jurassic-Cretaceous boundary in the external Rif chain (Mesorif area and Bou Haddoud nappe), numerous submarine volcanism traces have been discovered in Upper Oxfordian to Upper Berriasian deposits. These traces display various aspects: volcaniclastic complexes incorporated within Upper Berriasian marls; volcanic lavas and basalt clasts included in the breccias with clay matrix of Upper Oxfordian to Lower Berriasian age, or in brecciated Lower Tothonian calcareous beds of the Early Tithonian. These submarine volcanic activities took place in a carbonate platform environment during the Kimmeridgian to Early Tithonian interval or in a pelagic basin from Late Tithonian onwards. They caused an intense brecciation of Upper Jurassic carbonate formations and a general dismantling of marly calcareous alternations of Upper Tithonian-Lower Berriasian. Therefore, the Upper Tithonian-Lower Berriasian deposits are marked by frequent stratigraphic gaps in many outcrops of Mesorif, Prerif areas and in the Bou Haddoud nappe.

The coordination of research and innovation activities relative to an emergent technology: the case of batteries for electric and hybrid vehicles; La coordination des activites de recherche et d'innovation dans les phases d'emergence: le cas des batteries pour vehicules electriques et hybrides

    In this thesis, we try to provide elements of a non-deterministic view of the coordination of research activities in the phase of emergence. Firstly, we try to identify the variables that determinate the strength and the characteristics of the imperative of coordination in this very preliminary period of an innovation process. Secondly, we try to evaluate the institutional arrangements that can effectively sustain the coordination of the activities of the various interdependent actors more or less involved in the innovation process. The basic idea of the thesis is that technological innovations do not originate as isolated according to a hypothetical underlying 'nature of the technology', especially when they are controversial and subject to great uncertainties as is the case with regard to batteries for Electric and hybrid Vehicles (EVs). Innovations appear to be generated by means of the interactions of a number of organizations belonging to different 'spheres' (different industries, scientific disciplines, public institutions, etc.). In order to validate a new area of opportunity which is still very uncertain at this preliminary stage, the competences and interests of these different organizations must be coordinated. Because of the complex mix of economic and technological barriers faced by the actors taking part in this innovation process, the area of batteries for electric and hybrid vehicles is the 'perfect laboratory' to investigate the institutional arrangements that can sustain the coordination of research and innovation activities relating to an emerging technology. The empirical and theoretical investigations are mainly focused on pre-competitive research consortia such as the United-States Advanced Battery Consortium (USABC). This case study is conducted through in-depth interviews with key-actors of the area of batteries and electric vehicles. We also use the results of an on-line experts opinions survey we performed.

    In France, spent fuels are in most cases reprocessed. The aim of the reprocessing is to separate the recyclable fissile materials (for instance, uranium and plutonium) of radioactive wastes. The industrial process used until now is the Purex (Plutonium Uranium Refining by EXtraction) process. Recently (1991), the CEA has undertaken researches on the fields of separation and transmutation of long-lived radionuclides as minor actinides. Some molecules with an amide function have been at first considered especially for the uranium extraction. In order to rationalize the research of new extracting molecules, some molecular modeling methods (quantum chemistry calculations, molecular mechanics) have been used. In fact, there are three determining parameters for a molecule to be a good extractant: it has to own: (1) one or several sites which present a sufficient electron density in order that the metallic cation be complexed (2) the smallest possible substituents to avoid interferences with the complexation (3) a sufficient lipophilic effect.

    Full Text Available Sustainable management of sites affected by past industrial activities in Wallonia: the stakes and the challenges of “risk assessment” within the framework of the new policy developments on (local soil pollutions. Risk-based land management is a concept that stands out more and more frequently in soil policies adopted by different European countries, as well as within the framework of the future European directive on soil protection. This concept intends to act as a lever for sustainable solution development in terms of rehabilitation by ensuring the following principles: (1 reduction of risks (human health, ecosystems allowing sites to be reused safely (concept of “fitness for use”; (2 prevention of any pollutant dispersion risk (concept of “environmental protection”; (3 long-term care while minimising the burden of controlling, maintenance and monitoring. These ideas have been taken as backdrop for the Walloon decree “on soil remediation and rehabilitation of disused economic activity sites”. Risk control has been taken as a key point for any decision related to historically polluted sites. However, to be effective, this option stands out that reliable and efficient methodological tools are available for land evaluation (risk assessment. Three decision-making tools, specifically developed for the intended applications in the Walloon Region, are presented in the paper: (1 a global risk evaluation method allowing ranking of polluted sites; (2 a method to decide, at the end of the first step of the investigation procedure (preliminary soil investigation, whether further investigations are required or not; (3 a methodological procedure to proceed to a detailed risk assessment at the end of the in-depth investigation step. Perspectives are proposed to improve these first tools. It has also been shown that the challenge of sustainable solutions for the management of polluted sites finally depends on answers that will be progressively developed by the scientific community. These have to take into account all aspects of the Walloon context.

    A French Act of Parliament passed on 30 December 1991 set out the main areas of research required to prepare solutions for the long-term management of high-level, long-lived radioactive waste. The three avenues of research listed in the Act included a feasibility study of the deep geological disposal of these waste, with responsibility for steering the study given to ANDRA, France National Agency for Radioactive Waste Management. Following government decisions taken in 1998, the study focused on two types of geological medium, clay and granite. The clay formations study is essentially based on results from an underground laboratory sited at the border between the Meuse and Haute-Marne departments, where the Callovo-Oxfordian argillite beds are being investigated. No site has yet been chosen for an underground laboratory for the granite study, so for the time being this will draw on generic work and on research carried out in laboratories outside France. ANDRA has decided to present an initial report on the results of its research programme, publishing a dossier on the work on clay formations in 2001 with a second dossier covering the work on granite due for release in 2002. This dossier is thus a review of the work carried out by ANDRA on the feasibility study into a radioactive waste repository in a clay formation. It represents one step in a process of studies and research work leading up to the submission of a report due in 2005 containing ANDRA conclusions on the feasibility of a repository in the clay formation.

    Selenium is an essential micro-nutrient for most of living organisms. However, toxic effects in several ecosystems have been reported in the literature. Toxicity comprehension is difficult due to the complexity of Se oxidation states in the environment. The aim of this thesis work was to acquire knowledge on the physiological and environmental factors involved in bioaccumulation and toxicity processes in the freshwater filter-feeding bivalve C. fluminea. The aims were: i) to define what the factors involved in Se bioaccumulation processes in the bivalve are, ii) to characterize Se bioaccumulation at different biological organisation levels, iii) to investigate Se toxic effects. First experiments, carried out for short term exposure duration (3 days), have permitted to underline the importance of Se chemical speciation in bioaccumulation processes in C. fluminea. It has been shown that the organic form, seleno-methionine, was much more bio-available than the inorganic forms, selenite and selenate. Moreover, the route of transfer was determinant in those processes. Inorganic forms have been better extracted by trophic route, whereas seleno-methionine has been better extracted by the direct route. In our experimental conditions, ventilation of the bivalve has not been a limiting factor for Se bioaccumulation by the direct route, whereas it has been for bioaccumulation by the trophic route. Ventilation has been largely modified by the presence of dissolved selenite and seleno-methionine. We have shown that the kinetics of seleno-methionine bioaccumulation are much more fast than those of selenite. Moreover, when introduced as SeMet, internalized Se appeared to be relatively remanent in soft tissues of C. fluminea in comparison with Se internalized when introduced as selenite. Subcellular and molecular distributions of these forms were very different. Finally, it has been shown that seleno-methionine and selenite could generate weak alterations of the anti-oxidant status and the genetic expression in C. fluminea. On the other hand, important ultrastructural modifications of gill tissues have been observed after selenite and seleno-methionine exposure. (author)

    Strains Rhodococcus is a metabolically versatile genus, commonly found in soils and sea water, markedly solvent tolerant and capable of catalyzing diverse transformation reactions of compounds present in crude oil. Among these, oxidation and catabolism of alkanes and aromatics, sulfur removal from aryl- and alkyl-sulfonates and other organo-sulfur compounds are useful characteristics. To better exploit the performance of strains exhibiting biotransformation of oil components (in particular desulfurization and hydrocarbon oxidation) we have developed efficient genetic tools for the engineering of Rhodococcus strains. Strong and constitutive promoters have been isolated and characterized. Strains have been constructed in which the careful overexpression of selected components of the desulfurization pathway leads to the enhancement of the sulfur removal activity in model systems.

    Using SAXS, conductivity and phase behaviour determination we show that concentrated solutions of extractants are organised in reverse oligomeric aggregates which have many features in common with reverse micelles. The aggregation numbers of these reverse globular aggregates as well as their interaction potential are determined experimentally. The sticky sphere interaction is responsible for the de-mixing on the oil phase when in equilibrium with excess oil. Prediction of conductivity as well as formation condition for the third phase is possible using standard liquid theory applied to the reverse micelles. The attractive interaction, modeled with the sticky sphere model proposed by Baxter, is the balance of steric stabilisation introduced by the hydrophobic tails of the extracting molecule and the Van der Waals forces between the highly polarizable water core of the reverse molecule concentration, number of carbon atoms of aliphatic solvents, as well as proton and Neodymium cation concentration. It is shown that van der Waals interactions with a Hamaker constant of 2.5 kT explains the behaviour of DMDBTDMA in dodecane. (author) 184 refs.

    The initial stage of a high level nuclear waste disposal will be characterised by a large heat release within the near-field environment of the canisters. This heat flux caused by radioactive decay will lead to an increase of temperature and a subsequent thermal gradient between the `hot` canisters and the `cold`geological medium. In addition, this thermal gradient will decrease with time due to the heat decay although it could last hundred years. What will be the consequences of such a thermal field varying both on space and time for the alteration of the different constituents of the near field environment. In particular, what could be the effects on the radionuclides migration in the accidental case of an early breach of a canister during the thermal stage? This study brings significant answers to these questions in the light of a performance assessment study. This work is supported by a triple methodological approach involving experimental studies, modelling calculations and a natural analogues study. This complete work demonstrates that a thermal gradient leads to a large re-distribution of elements within the system: some elements are incorporated in the solid phases of the hot end (Si, Zr, Ca) whereas some others are in those of the cold end (Fe, Al, Zn). The confrontation of the results of very simple experiments with the results of a model built on equilibrium thermodynamics allow us to evidence the probable mechanisms causing this mass transport: out-of-equilibrium thermodiffusion processes coupled to irreversible precipitation. Moreover, the effects of the variation of temperatures with time is studied by the way of a natural system which underwent a similar temperature evolution as a disposal and which was initially rich in uranium: the Jurassic Alpine bauxites. In addition, part of the initial bauxite escaped this temperature transformations due to their incorporation in outer thrusting nappes. They are used as a reference. (author)

    Pyrochemical separation methods using high temperature molten salt media could emerge as promising and valuable routes compared with aqueous methods for separation and transmutation strategies for long-lived radionuclides. A good knowledge of the molten salt chemistry is essential for controlling these separations, and elementary data are required for molten halide salts, which can be readily provided by electrochemical methods. Applying the chemical principles of aqueous solutions to the molten salt media, Pourbaix diagrams - called in this case potential-oxo-acidity (pO{sup 2-}) - can be plotted. They offer a rapid and comprehensive view of the thermodynamic properties of selected elements in a solvent of interest. Two methods are available for preparing these diagrams. The first is based on available thermodynamic data on pure element oxide (and oxychloride) compounds and on element chloride activity coefficients in melt (which can be electrochemically determined). In this method, we consider the oxide anion exchange reactions between the pure compounds, water and hydrogen chloride. The second method is a direct and experimental determination of the oxo-acidic properties of the studied element chlorides in melts. Use of an Yttria-Stabilised Zirconia Membrane (YSZM) electrode (oxide anion selective electrode) helps determine the nature of the stable oxide compounds in melts as well as their stabilities. The YSZM is used with a silver/silver chloride reference system, and was developed 25 years ago. Two examples of Potential-acidity diagrams. Employing the first method and the determination of the standard potential of plutonium in LiCl-KCl and NaCl-KCl eutectic mixtures, potential-oxo-acidity diagrams were plotted for these melts at various temperatures. It was found that the stability domain for plutonium chloride depends on the melt composition (influence of oxide anion solvation). We also used the Omega acidity function - based on reaction (1) - which is a function of state, since it is only dependent on gas partial pressures. The pO{sup 2-} entity characterizing the melt oxo-acidity is accordingly related to Omega. The knowledge of the equilibrium constant K allows calibration of the pO{sup 2-} scale with respect to the universal Omega scale. Note also that while pO{sup 2-} and pK depend on the melt temperature and composition, this is not the case for the term involving the partial pressures of hydrogen chloride and water, so that Omega can be set independently of the working temperature. Universal potential-acidity diagrams were thus prepared. In the first method, the oxychloride is assumed to be insoluble. We therefore preferred to determine experimentally the stabilities of the element oxychloride and oxide and their physical state (solvated or precipitated) in the melt, considering the second method. For instance, the well-known cerium system was used to validate the YSZM electrode operating procedure, and potentiometric titrations of cerium chloride with carbonate anion serve to characterize the speciation of cerium in the melts as a function of acidity. Similar experiments are planned with plutonium and americium compounds. (author)

    The influence of the size of molybdenum disulfide particles supported on alumina on hydro-desulfurization and hydrogenation reactions has been studied. Different methods have been used to modify the length and the stacking of MoS{sub 2} slabs. MoS{sub 2} slab length measured from Electron Microscopy is increased from 20 to 40 angstroms by increasing loading from 4 to 22 % pds in Mo. These catalysts have been tested and characterised by different techniques. Increasing the sulfiding temperature also leads to an increase in MoS{sub 2} slab length. Bulk MoS{sub 2} and MoS{sub 2}/Al{sub 2}O{sub 3} showing high MoS{sub 2} slab stacking have been prepared from ammonium tetra-thio-molybdate salt. Sulfide phase characterisation results and an hexagonal MoS{sub 2} slab model have been used to estimate a number of edge and corner Mo ions. Catalysts have been characterised by Temperature Programmed Reduction and by CO adsorption at low temperatures (infra-red). Edge and corner Mo ions site densities determined by these techniques are linearly correlated with the number of sites calculated from the hexagonal MoS{sub 2} slab model and the characterisation results. Catalysts have been tested at 350 deg. C, under a total pressure of 4,5 MPa for dibenzo-thiophene hydro-desulfurization and 1-methyl naphthalene hydrogenation in the presence of nitrogen compounds. Linear correlations have been obtained between the catalytic activity and the number of edge and corner Mo sites estimated from different techniques. These results obtained from independent techniques clearly show the essential part played by edge and corner sites on catalytic activity. MoS{sub 2} slab length has no influence on the selectivity hydrogenation/hydro-desulfurization of tested catalysts. On the other side, the increase o stacking of MoS{sub 2} slab un-favours the hydrogenation reaction when compared to the hydro-desulfurization reaction. (author) 169 refs.

    This study deals with a new method that makes it possible to measure very low tritium quantities inside radioactive waste drums. This indirect method is based on measuring the decaying product, {sup 3}He, and requires a study of its behaviour inside the drum. Our model considers {sup 3}He as totally free and its leak through the polymeric joint of the drum as two distinct phenomena: permeation and laminar flow. The numerical simulations show that a pseudo-stationary state takes place. Thus, the {sup 3}He leak corresponds to the tritium activity inside the drum but it appears, however, that the leak peaks when the atmospheric pressure variations induce an overpressure in the drum. Nevertheless, the confinement of a drum in a tight chamber makes it possible to quantify the {sup 3}He leak. This is a non-intrusive measurement of its activity, which was experimentally checked by using reduced models, representing the drum and its confinement chamber. The drum's confinement was optimised to obtain a reproducible {sup 3}He leak measurement. The gaseous samples taken from the chamber were purified using selective adsorption onto activated charcoals at 77 K to remove the tritium and pre-concentrate the {sup 3}He. The samples were measured using a leak detector mass spectrometer. The adaptation of the signal acquisition and the optimisation of the analysis parameters made it possible to reach the stability of the external calibrations using standard gases with a {sup 3}He detection limit of 0.05 ppb. Repeated confinement of the reference drums demonstrated the accuracy of this method. The uncertainty of this non-intrusive measurement of the tritium activity in 200-liter drums is 15% and the detection limit is about 1 GBq after a 24 h confinement. These results led to the definition of an automated tool able to systematically measure the tritium activity of all storage waste drums. (authors)

    The government decided to engage France in a firm action of reducing the pollutant emission damaging the environment or producing the greenhouse effect. To this aim the taxation upon the consumptions of rare resources the use of which results in an important pressure upon environment, as the energy for instance, constitutes an essential complement to other tools, as for instance, regulations, technical norms, ecological labels, assistance for investments, etc. Thus the fiscal policy constitutes a perennial lever of inciting actors, particularly those acting in economy, to optimize and control their energy consumption or to reduce their greenhouse gas emission. Any pollutant emission avoided represents not only a supplementary protection of the environment but also, in time, the avoidance of a reparatory expenditure for the entire society. To this aim the Parliament has approved in 1999 the creation of a general tax on polluting activities (TGAP) intended to prevent first the local and diffuse pollutions which will be enlarged since 2001 to prevent the global pollutions, first of those resulting from greenhouse gas emissions. France engaged itself in the frame of Kyoto conference protocol, adopted in December 1997, to stabilize in 2010 its gas emissions to the level attained in 1990. Actually, taking into account the prospects for economic growth, this engagement needs supplementary efforts. The government's decision, announced last 20 May, of enlarging the TGAP since 2001 to intermediary energy consumptions, is a contribution to this objective. Concerned about the France industry competitiveness, namely to the particular situation of the intensive energy enterprises, exposed to international competition, the government judged advisable to proceed in a large consultation of the concerned economic actors before implementing this enlargement. The White Book makes this engagement concrete. The accuracy of the answers given to the questions, posed in its second part, will allow clarifying the choices of the government in implementing this reform. Tool of inciting and preventing, the enlarged TGAP, allows add to the dividends obtained for environmental protection the resources of a second dividend, the dividend for employment. By substituting for other mandatory taxes pressing on labour, the TGAP will be entirely allotted to lower the social employment quotas. The document presents the government's program, introduces the principles of ecological fiscal policy and the topics of greenhouse effect.

    Nuclear industry pays a particular attention to structures integrity problems: well-aware of the possible catastrophic consequence of a major accident, everything is carried out to minimise the risk of such a situation. From the design, and during all the operating life of the plant, a high level of safety is required and checks by the safety authorities, on the basis of reports made by the operator. These two entities ask for R and D activities to support the improvement of the knowledge of the phenomena already identified (as in the case of the vessel of the PWR) or to bring some element of understanding to situation not considered yet, up to the first incident (as in 1998 with the fatigue problems in the thermal mixing zone, at the origin of the Civaux arrest). Among the CEA teams concerned with these problems, the Laboratory of the Structures Integrity and of Normalisation aims to study the integrity problems in metallic nuclear structures leaning on exceptional experimental means: the RESEDA platform allows the realisation of large-scaled tests on analytical tests (representative of analysed phenomena) to reproduce the industrial situation, linked to various and accurate equipment for the measures and the analyses. Three industrial thematics represent to main part of my research activities at CEA in the fracture mechanics field: - the industrial case of the PWR vessel is related to brittle fracture of the ferritic steels, - the piping components, related to ductile tearing and fracture in the brittle-to-ductile domain, - the high temperature fracture mechanics for the components submitted to very complex loadings.

Estudio descriptivo, prospectivo, de 27 meses, incluyéndose 563 pacientes, valorando carga de trabajo según Nursing Activities Score. Existieron diferencias significativas en la carga de trabajo al ingreso y en el alta entre los grupos de pacientes, siendo superior en ambos momentos la de pacientes con insuficiencia respiratoria aguda y sepsis frente a pacientes coronarios. Durante los siete primeros días de estancia se mantuvo esta diferencia, desapareciendo a partir del octavo día, equilibrándose la carga de trabajo para los tres grupos. Para conseguir una adecuada dotación de personal es fundamental contar con instrumentos para medir las necesidades de cuidados y conocer la carga de trabajo de los distintos grupos de enfermos que ingresan con mayor frecuencia en las unidades de terapia intensiva.O objetivo deste estudo foi avaliar a carga de trabalho na admissão e alta dos pacientes de três grupos (síndrome coronária aguda, insuficiência respiratória aguda e sepsis em cuidados intensivos. Trata-se de estudo prospectivo, descritivo, que decorreu durante 27 meses, incluindo 563 pacientes. Para a avaliação da carga de trabalho utilizou-se a escala Nursing Activities Score. A partir dos resultados do estudo parecem existir diferenças significativas na carga de trabalho no dia da admissão e alta entre os grupos de pacientes, sendo a carga maior em ambos os tempos a dos pacientes com insuficiência respiratória aguda e sepsis. Durante os primeiros sete dias de internamento essa diferença manteve-se, desaparecendo no oitavo dia, o que equilibrou a carga de trabalho para os três grupos. Conclui-se que para se conseguir os recursos adequados é essencial dispor de instrumentos para medir as necessidades de cuidados e conhecer a carga de trabalho dos diferentes grupos de pacientes que passam com mais frequência pelas unidades de cuidados intensivos.The purpose of this study was to assess the nursing workload at admission to and discharge from intensive care of three groups of patients (i.e., acute coronary syndrome, acute respiratory failure, and sepsis. A prospective, descriptive study was performed over a 27-month period and included 563 patients. The workload was assessed using the Nursing Activities Score scale. Significant differences in the workload were determined on the days of admission and discharge: the workload was higher in both cases for patients with acute respiratory failure and sepsis compared with patients diagnosed with acute coronary syndrome. This difference was maintained over the first seven days of their hospital stay. From day 8 on, the difference disappeared, and a workload balance was achieved in the three groups. Good staffing requires adequate tools for measuring care needs and understanding the workload required in the groups of patients who are most frequently admitted to intensive care.

    In the days following high-dose radiation exposure, damage to small intestinal mucosa is aggravated by changes in the bile acid pool reaching the gut. Intestinal bile acid malabsorption, as described classically, may be associated with altered hepatic bile acid biosynthesis, which was the objective of this work. The activity of the main rate-limiting enzymes implicated in the bile acid biosynthesis were evaluated in the days following an 8-Gy {gamma} Co{sup 60} total body irradiation of rats, with concomitant determination of biliary bile acid profiles and intestinal bile acid content. Modifications of biliary bile acid profiles, observed as early as the first post-irradiation day, were most marked at the third and fourth day, and resulted in an increased hydrophobicity index. In parallel, the intestinal bile acids' content was enhanced and hepatic enzymatic activities leading to bile acids were changed. A marked increase of sterol 12-hydroxylase and decrease of oxy-sterol 7-hydroxylase activity was observed at day 3, whereas both cholesterol 7-hydroxylase and oxy-sterol 7-hydroxylase activities were decreased at day 4 after irradiation. These results show, for the first time, radiation-induced modifications of hepatic enzymatic activities implicated in bile acid biosynthesis and suggest that they are mainly a consequence of radiation-altered intestinal absorption, which induces a physiological response of the entero-hepatic bile acid recirculation.

    We have studied prospectively the usefulness of HMPAO [sup 99m]Tc leucocytes scan in patients with Crohn's disease and ulcerative colitis. Abdominal scans were performed 1 h and 2 h 30 after injection of an autologous leukocyte preparation containing 100-200 MBq of Technetium 99m. The extent of bowel involvement, evaluated on the 2 h 30 scan, was compared to X-rays and endoscopic findings. The disease activity was quantified by the intensity of intestinal radionuclide uptake on the 2 h 30 scan and compared with the Crohn's disease activity index (CDAI) sedimentation rate. Forty-five examinations were performed in 40 patients with Crohn's disease or ulcerative colitis. The correlation of the number of locations between leukocyte scan and other diagnosis procedures was good in 40 cases. CDAI was significantly correlated with radionuclide index. Two fistulae and one abscess and small bowel involvement were correctly visualized. This technique provides images of excellent quality, superior to those obtained with indium 111. Therefore, we believe that this test can be useful in the follow-up of patients with Crohn's disease and ulcerative colitis.

    The aim of this work is to determine the effect of irradiation on the alteration of high level nuclear waste forms matrices. The matrices investigated are UO{sub 2} to simulate the spent fuel, the hollandite for the specific conditioning of Cs, and the inactive glass SON68 representing the nuclear glass R7T7) The alpha irradiation experiments on UO{sub 2} colloids in aqueous carbonate media have enabled to distinguish between the oxidation of UO{sub 2} matrix as initial and dissolution as subsequent step. The simultaneous presence of carbonate and H{sub 2}O{sub 2} (product resulting from water radiolysis) increased the dissolution rate of UO{sub 2} to its maximum value governed by the oxidation rate. ii) The study of hollandite alteration under gamma irradiation confirmed the good retention capacity for Cs and Ba. Gamma irradiation had brought only a little influence on releasing of Cs and Ba in solution. Electronic irradiation had conducted to the amorphization of the hollandite only for a dose 1000 times higher than the auto-induced dose of Ba over millions of years. iii) The experiences of glass irradiation under alpha beam and of helium implantation in the glass SON68 were analyzed by positon annihilation spectroscopy. No effect has been observed on the solid surface for an irradiation dose equal to 1000 years of storage. (author)

    Whatever the level in an organization, the management needs safety indicators to assist decision making on safety. As an indicator, PSA (Probabilistic Safety Assessment) through PHRA (Probabilistic Human Reliability Assessment) accounts for some aspects of human reality. In spite of the limitations of PSAs as a tool in assisting the processing of safety problems, three possible channels for development and progress are suggested ``internal`` improvement of PSAs, by enhancing data and human-behaviour models; extension of the classical applications of PSAs for the purpose of reflection and speculation, and for querying the potential influence of a certain number of factors concerning human behaviour; the extension of PSAs themselves, by developing organizational indicators. Research has been undertaken to evaluate the feasibility of using methods developed for analysis of the psychosocial climate of a company to set up a ``safety culture`` or ``safety climate`` indicator. Such an organizational indicator would reflect perception and opinion of the personnel at a given time, and make it possible to follow their evolutions; effective interpretation of the results needs to be done with the staff concerned. PSA and other indicators are only tools for analysis and aids for decision making, they cannot replace any part of the technical and scientific debate which must be on-going for all aspects of safety.

Decne: competitive effect of the aqueous extracts of the plant and the testosterone propionate on castrated immature rats. The anti-androgenic activity and the evaluation of competitiveness between the extracts of Leptadenia hastata and the testosterone propionate (TP were studied on Wistar immature castrated rats. The first group received only 0.04; 0.4; 4; 40; 400 and 1,000 µg.kg-1 of TP and the second group received simultaneously these different doses of TP and 200 mg.kg-1 of L. hastata. The various treatments showed a significant increase (p < 0.05 of the weight of androgeno-dependent organs and the level of plasmatic testosterone. At low dosis of TP, the dosis of 200 mg.kg-1 of L. hastata inhibited TP effects, whereas at high doses of TP L. hastata extracts potentiated TP effects. In conclusion, the anti-androgenic effect of the extract of L. hastata is expressed when the TP amounts are weak.

    The surveillance of the temporal evolution of radon and helium concentrations in the carbon dioxide of crater fumaroles and gaseous emanations is performed since 1992 on the Irazu, Arenal, Poas and Rincon de la Vieja volcanoes in Costa-Rica. The {sup 3}He/{sup 4}He ratio is used as an indicator of the deep origin of the volcanic gas while radon is an indicator of the CO{sub 2} flux. Radon measurements performed on the Irazu show a continuous decay of radon concentration in the intra-crater fumaroles with an important increase of the gaseous flux since 1992. On the contrary, the external fumaroles on the NW flank were characterized by an important increase in radon concentration in 1994 with a stable flux. The radon surveillance performed in soils around the volcano has shown an intense increase of the diffuse gaseous flows probably linked to the micro-seismic activity of the volcano. Similar observations are reported for the Rincon de la Vieja volcano and correlated with its eruptive history and its phreatic and phreato-magmatic activity. Short paper. (J.S.).

    Modern oceanographical studies shown that most of the ocean heat content in the North Atlantic Western Boundary Current region is stored in the upper 400 meters. To study past heat content and Gulf Stream activity, we performed coupled analyses of oxygen isotopic and trace elemental composition on several foraminifera species to reconstruct upper water column temperature and salinity. Calcification depths of Globorotalia inflata, Globorotalia truncatulinoides and Pulleniatina obliquiloculata have been constrain by correlating modern hydrographic data to oxygen isotopic measurement of North Atlantic core-top samples. We found that the three deep-dwelling foraminifera species have a preferred habitat at the base of the seasonal thermocline (Cleroux et al, 2007). The same set of North Atlantic core-tops has been used to define relationships between trace elemental compositions and temperature. We established calibrations between Mg/Ca ratio or Sr/Ca ratio and temperature for the three deep-dwelling foraminifera (Cleroux et al, submitted). We apply this strategy on the core MD99-2203 located off Cape Hatteras where the Gulf Stream separate from the United States coast. High-resolution surface reconstructions over the Holocene show low amplitude periodic temperature and salinity changes that could be related to NAO type mechanisms. Large hydrological changes in sub-surface reflect variations of Labrador current and Mode Water influences. Using recent studies on Mode Water formation and Gulf Stream heat advection, we interpret our results in term of ocean heat content and Gulf Stream activity. (author)

    Full Text Available Storici dell’arte ed esperti del settore museale lamentano la difficoltà del pubblico a “leggere” le opere esposte in un museo di arti visive. Guardare e cogliere gli aspetti relativi alla grammatica visiva di un oggetto sono abilità che si apprendono, in generale non sono innate o spontanee. I fruitori potrebbero beneficiare di un metodo che sviluppa e potenzia le loro capacità visive. Lo scopo di questo articolo è presentare e valutare se un modello basato sul priming percettivo, una forma di memoria implicita, possa migliorare la metodologia per leggere gli aspetti visivi del patrimonio artistico. A complemento del lavoro proposto, vengono qui introdotti anche alcuni risultati preliminari di un nuovo promettente approccio sperimentato, che consiste nella analisi dei segnali elettroencefalografici dei soggetti coinvolti, raccolti attraverso un dispositivo per EEG durante la fase di verifica dell’esperimento sul priming percettivo. Art historians and museum practitioners complained about the lack of “reading skills” in observing artworks by museum visitors. Reading and analysing visual grammar aspects of an artistic object are skills that require learning: not innate or spontaneous. Museum goers could benefit from method developing and enhancing their visualization skills. The purpose of this article is to present and assess whether a model based on “visual-perceptual priming”, a form of implicit memory, could improve the methodology of reading visual aspects of artworks. We also introduce some preliminary results obtained from a promising new approach consisting the analysis of electroencephalographic signals from individuals, collected through an EEG device during the experiment on the visual-perceptual priming
