Extension of Wu-Peters bounds to Catmull-Clark and 4-8 subdivision

La méthode de subdivision Catmull-Clark ainsi que la méthode de subdivision Loop sont des normes industrielle de facto. D'autre part, la méthode de subdivision 4-8 est bien adaptée à la subdivision adaptative, parce que cette méthode augmente le nombre de faces ou de sommets par seulement un facteur de 2 à chaque raffinement. Cela promet d'être plus pratique pour atteindre un niveau donné de précision. Dans ce mémoire, nous présenterons une méthode permettant de paramétrer des surfaces de subdivision de la méthode Catmull-Clark et de la méthode 4-8. Par conséquent, de nombreux algorithmes mis au point pour des surfaces paramétriques pourrant être appliqués aux surfaces de subdivision Catmull-Clark et aux surfaces de subdivision 4-8. En particulier, nous pouvons calculer des bornes garanties et réalistes sur les patches, un peu comme les bornes correspondantes données par Wu-Peters pour la méthode de subdivision Loop.

L’extinction de l'extension juridique des conventions collectives dans le secteur manufacturier au Québec : le cas de l'industrie du vêtement

RÉSUMÉ Le gouvernement du Québec a adopté en novembre 1999 le projet de loi 47, relatif à la Loi concernant les conditions de travail dans certains secteurs de l’industrie du vêtement et modifiant la Loi sur les normes du travail (1999, c. 57). Son entrée en vigueur eut pour effet d’abroger au 30 juin 2000 les quatre (4) décrets sectoriels de convention collective qui régissaient les conditions d’emploi d’approximativement 23 000 travailleurs affectés à la production de vêtements (gant de cuir, chemise pour hommes et garçons, confection pour hommes et pour dames). Cette recherche démontre que bien qu’inscrit dans une logique étatique de dérégulation du travail visant à favoriser la compétitivité, le maintien de normes de substitution aux décrets dans le cas du vêtement québécois ne dérive pas pour autant d’une déréglementation strictement néolibérale. Au plan plus théorique, l’émergence et le sort du régime de conditions d’emploi étudié dévoilent la nature politique du processus d’élaboration des règles salariales, qu’il soit d’origine législative ou contractuelle. Cette dynamique repose sur le caractère mouvant des relations de pouvoir et d’influence des agents engagés dans la régulation institutionnelle, où l’État est appelé à jouer un rôle de catalyseur ─ et non de tiers arbitre indépendant ─ à l’endroit des tensions qui procèdent du rapport salarial et du mode de production au sein duquel il s’inscrit.

Effect of albumin dialysis on intracranial pressure increase in pigs with acute liver failure: a randomized study.

BACKGROUND: Increased intracranial pressure (ICP) worsens the outcome of acute liver failure (ALF). This study investigates the underlying pathophysiological mechanisms and evaluates the therapeutic effect of albumin dialysis in ALF with use of the Molecular Adsorbents Recirculating System without hemofiltration/dialysis (modified, M-MARS). METHODS: Pigs were randomized into three groups: sham, ALF, and ALF + M-MARS. ALF was induced by hepatic devascularization (time = 0). M-MARS began at time = 2 and ended with the experiment at time = 6. ICP, arterial ammonia, brain water, cerebral blood flow (CBF), and plasma inflammatory markers were measured. RESULTS: ICP and arterial ammonia increased significantly over 6 hrs in the ALF group, in comparison with the sham group. M-MARS attenuated (did not normalize) the increased ICP in the ALF group, whereas arterial ammonia was unaltered by M-MARS. Brain water in the frontal cortex (grey matter) and in the subcortical white matter at 6 hrs was significantly higher in the ALF group than in the sham group. M-MARS prevented a rise in water content, but only in white matter. CBF and inflammatory mediators remained unchanged in all groups. CONCLUSION: The initial development of cerebral edema and increased ICP occurs independently of CBF changes in this noninflammatory model of ALF. Factor(s) other than or in addition to hyperammonemia are important, however, and may be more amenable to alteration by albumin dialysis.

Association of reduced extracellular brain ammonia, lactate, and intracranial pressure in pigs with acute liver failure.

We previously demonstrated in pigs with acute liver failure (ALF) that albumin dialysis using the molecular adsorbents recirculating system (MARS) attenuated a rise in intracranial pressure (ICP). This was independent of changes in arterial ammonia, cerebral blood flow and inflammation, allowing alternative hypotheses to be tested. The aims of the present study were to determine whether changes in cerebral extracellular ammonia, lactate, glutamine, glutamate, and energy metabolites were associated with the beneficial effects of MARS on ICP. Three randomized groups [sham, ALF (induced by portacaval anastomosis and hepatic artery ligation), and ALF+MARS] were studied over a 6-hour period with a 4-hour MARS treatment given beginning 2 hours after devascularization. Using cerebral microdialysis, the ALF-induced increase in extracellular brain ammonia, lactate, and glutamate was significantly attenuated in the ALF+MARS group as well as the increases in extracellular lactate/pyruvate and lactate/glucose ratios. The percent change in extracellular brain ammonia correlated with the percent change in ICP (r(2) = 0.511). Increases in brain lactate dehydrogenase activity and mitochondrial complex activity for complex IV were found in ALF compared with those in the sham, which was unaffected by MARS treatment. Brain oxygen consumption did not differ among the study groups. Conclusion: The observation that brain oxygen consumption and mitochondrial complex enzyme activity changed in parallel in both ALF- and MARS-treated animals indicates that the attenuation of increased extracellular brain ammonia (and extracellular brain glutamate) in the MARS-treated animals reduces energy demand and increases supply, resulting in attenuation of increased extracellular brain lactate. The mechanism of how MARS reduces extracellular brain ammonia requires further investigation.
