Relationship between monitored elements and prescribed ventilator setting modifications in critically ill children

Les pédiatres intensivistes ont plusieurs éléments disponibles pour guider leurs décisions par rapport à la ventilation mécanique. Par contre, aucune étude prospective ne décrit les éléments auxquels les intensivistes se réfèrent pour modifier les paramètres du respirateur. Objectifs : Décrire la pratique actuelle de la modification des paramètres du respirateur aux soins intensifs du CHU Sainte-Justine, un hôpital pédiatrique tertiaire. Hypothèse : 80% des modifications des paramètres du respirateur influant sur l’épuration du CO2 sont liées à l’analyse de la PCO2 ou du pH et 80% des modifications des paramètres d’oxygénation sont liés à l’analyse de l’oxymétrie de pouls. Méthodes : En se servant d’un logiciel de recueil de données, les soignants ont enregistré un critère de décision primaire et tous les critères de décision secondaires menant à chaque modification de paramètre du respirateur au moment même de la modification. Résultats : Parmi les 194 modifications des paramètres du respirateur influant sur l’épuration du CO2, faites chez vingts patients, 42.3% ±7.0% avaient pour critère primaire la PCO2 ou le pH sanguin. Parmi les 41 modifications de la pression expiratoire positive et les 813 modifications de la fraction d’oxygène inspirée, 34.1% ±14.5% et 84.5% ±2.5% avaient pour critère primaire l’oxymétrie de pouls, respectivement. Conclusion : Les médecins surestiment le rôle de la PCO2 et du pH sanguins et sousestiment le rôle d’autres critères de décision dans la gestion de la ventilation mécanique. L’amélioration de notre compréhension de la pratique courante devrait aider à l’éboration des systèmes d’aide à la décision clinique en assistance respiratoire.

The Constitutional basis of aboriginal rights

Aboriginal rights are rights held by aboriginal peoples, not by virtue of Crown grant, legislation or treaty, but “by reason of the fact that aboriginal peoples were once independent, self-governing entities in possession of most of the lands now making up Canada.” It is, of course, the presence of aboriginal peoples in North America before the arrival of the Europeans that distinguishes them from other minority groups in Canada, and explains why their rights have special legal status. However, the extent to which those rights had survived European settlement was in considerable doubt until as late as 1973, which was when the Supreme Court of Canada decided the Calder case.2 In that case, six of the seven judges held that the Nishga people of British Columbia possessed aboriginal rights to their lands that had survived European settlement. The actual outcome of the case was inconclusive, because the six judges split evenly on the question whether the rights had been validly extinguished or not. However, the recognition of the rights was significant, and caught the attention of the Government of Canada, which began to negotiate treaties (now called land claims agreements) with First Nations in those parts of the country that were without treaties. That resumed a policy that had been abandoned in the 1920s, when the last numbered treaty was entered into.

Les réseaux militaires comme acteurs des relations internationales : le cas du Multinational Interoperability Council

Depuis plus de cinquante ans, les puissances occidentales ont créé toutes sortes de réseaux militaires internationaux, afin de renforcer leurs liens et harmoniser leurs techniques, leurs équipements et leurs façons de faire. Jusqu’à ce jour, ces regroupements sont demeurés largement ignorés de la discipline des relations internationales. Or, la mondialisation des échanges et l’essor des technologies de l’information ont ouvert les processus politiques à de nouveaux acteurs, y compris en matière de sécurité, jetant un éclairage nouveau sur le rôle, la mission et les responsabilités que les États délèguent à ces réseaux. En menant une analyse approfondie d’un réseau militaire, le Multinational Interoperability Council, cette recherche a pour objectifs de définir les réseaux militaires internationaux en tant que catégorie d’analyse des relations internationales, de documenter empiriquement leur fonctionnement et de mieux comprendre leur rôle dans le champ de la sécurité internationale. Pour ce faire, la démarche propose de recourir à l’appareil conceptuel de l’institutionnalisme relationnel, de la théorie des champs et du tournant pratiques en relations internationales. Cette combinaison permet d’aborder les dimensions institutionnelle, cognitive et pratique de l’action collective au sein du réseau étudié. L’analyse nous apprend que, malgré une influence limitée, le MIC produit une identité, des capacités, des préférences et des effets qui lui sont propres. Les acteurs du MIC ont eux-mêmes généré certaines conditions de son institutionnalisation, et sont parvenus à faire du réseau, d’abord conçu comme une structure d’échanges d’informations, un acteur intentionnel du champ de la sécurité internationale. Le MIC ne peut agir de façon autonome, sans contrôle des États. Cependant, les relations établies entre les militaires qui y participent leur offrent des capacités – le capital social, politique et d’expertise – dont ils ne disposeraient pas autrement, et qu’ils peuvent mobiliser dans leurs interactions avec les autres acteurs du champ.

Science and technology of rubber reclamation with special attention to NR-based waste latex products

A comprehensive overview of reclamation of cured rubber with special emphasis on latex reclamation is depicted in this paper. The latex industry has expanded over the years to meet the world demands for gloves, condoms, latex thread, etc. Due to the strict specifications for the products and the unstable nature of the latex as high as 15% of the final latex products are rejected. As waste latex rubber (WLR) represents a source of high-quality rubber hydrocarbon, it is a potential candidate for generating reclaimed rubber of superior quality. The role of the different components in the reclamation recipe is explained and the reaction mechanism and chemistry during reclamation are discussed in detail. Different types of reclaiming processes are described with special reference to processes, which selectively cleave the cross links in the vulcanized rubber. The state-of-the-art techniques of reclamation with special attention on latex treatment are reviewed. An overview of the latest development concerning the fundamental studies in the field of rubber recycling by means of low-molecular weight compounds is described. A mathematical model description of main-chain and crosslink scission during devulcanization of a rubber vulcanizate is also given.

Effect of Diphenyldisulfides with Different Substituents on the Reclamation of NR Based Latex Products

The latex industry has expanded over the years to meet the world demands for gloves, condoms, latex thread etc. Because of the strict specifications for the products and the unstable nature of the latex, as high as 15%, of the final latex products are rejected. Since waste latex rubber (WLR) represents a source of high quality rubber hydrocarbon, it is a potential candidate for generating reclaimed rubber of superior quality. Two types of WLR with different amounts of polysulfidic bridges are used in these experiments, which are reclaimed with variation of the concentration of the reclaiming agents, the reclamation temperature and time, Di phenyldisultide, 2-aminophenyldisulfide and 2,2'-dibenzamidodiphenyldisulfide (DBADPDS) are used as reclaiming agents, and the effect of diphenyldisulfides (DPDS) with different substituents, on the reclamation efficiency of WLR is investigated. A kinetic study of the reclamation reaction with the three reclaiming agents is done. The reaction rates and activation energies are calculated and compared with literature values. The comparative study of the three different reclaiming agents shows that (DBADPDS) is able to break the crosslinks at temperature levels 20'C below the temperature levels normally used with DPDS. Another advantage of this reclaiming agent is the reduced smell during the reclamation process and of the final reclaims, one of the most important shortcomings of other disulfides used for this purpose.

Occurrence of filamentous algae and soil characteristics in the paddy fields of Kuttanad and Kole lands of Kerala

The present work is the study of filamentous algae in the paddy fields of Kuttanad and Kole lands of Kerala. This investigation was initiated by sampling of filamentous algae in Kuttanad during December 2010 to February 2011. A second phase of sampling was done from November 2011 to February 2012. The sampling periodicity corresponded to the crop growth starting from field preparation through sowing, and continued till the harvest. Sampling locations were selected from the active paddy cultivation regions of the six agronomic zones of Kuttanad. The numbers of sampling locations were proportional to the area of each zone. Algae of the Kole lands were collected during from October 2011 to January 2012. It was observed that blue-green algae dominated in both Kuttanad and Kole lands. Thirty two species of blue-green algae and eight species of green algae were identified from Kuttanad. The highest number of algal species was observed from Kayal lands in Kuttanad throughout the cropping season. Among the thirty two species of blue-green algae twenty five species are nonheterocystous and seven species are heterocystous. Twenty eight species of blue-green and six species of green algae were identified from Kole lands, and highest number of species was observed in Palakkal throughout the cropping season. Among the twenty eight species of blue-green algae collected from Kole lands twenty one species are non-heterocystous, and only seven species are heterocystous filamentous algae. Blooms of Spirogyra were observed during the second phase of sampling in Kuttanad and also in the Kole lands. The results of the germination study revealed that the extract of Spirogyra sp. inhibited seed germination and reduced seedling vigour. The growth of the treated seedlings was evaluated by pot experiments. The results clearly showed that Spirogyra sp. can negatively affect the seed germination, seedling vigour, and the yield of rice.

Changes in amino acid enantiomers and microbial performance in soils from a subtropical mountain oasis in Oman abandoned for different periods

An important feature of maintaining the agricultural stability in millennia-old mountain oases of northern Oman is the temporary abandonment of terraces. To analyse the effects of a fallow period on soil microbial performance, i.e. microbial activity and microbial biomass, samples of eight terrace soils abandoned for different periods were collected in situ, assigned to four fallow age classes and incubated for 30 days in the laboratory after rewetting. The younger fallow age classes of 1 and 5 years were based on the records of the farmers’ recollections, the two older fallow age classes of 10–20 and 25–60 years according to the increase in the D -to- L ratio of valine and leucine enantiomers. The increase in these two ratios was in agreement with that of the D -to- L ratio of lysine. The strongest relationship was observed between the increase in the D -to- L ratio of lysine and the decrease in soil microbial biomass C. However, the most stringent coherence between the increase in fallow age and soil properties was revealed by the decreases in cumulative respiration and net N mineralisation rates with decreasing availability of substrate to soil microorganisms. During the 30-day incubation following rewetting, relative changes in microbial activity (respiration and net N mineralisation) and microbial biomass (C and N)indices were similar in the eight terrace soils on a fallow age-class-specific level, indicating that the same basic processes occurred in all of the sandy terrace soils investigated.
