Purpose - This paper seeks to develop a sub-domain perturbation technique to efficiently calculate strong skin and proximity effects in conductors within frequency and time domain finite element (FE) analyses. Design/methodology/approach - A reference eddy current FE problem is first solved by considering perfect conductors. This is done via appropriate boundary conditions (BCs) on the conductors. Next the solution of the reference problem gives the source for eddy current FE perturbation sub-problems in each conductor then considered with a finite conductivity. Each of these problems requires an appropriate volume mesh of the associated conductor and its surrounding region. Findings - The skin and proximity effects in both active and passive conductors can be accurately determined in a wide frequency range, allowing for precise losses calculations in inductors as well as in external conducting pieces. Originality/value - The developed method allows one to accurately determine the current density distributions and ensuing losses in conductors of any shape, not only in the frequency domain but also in the time domain. Therefore, it extends the domain of validity and applicability of impedance-type BC techniques. It also offers an original way to uncouple FE regions that allows the solution process to be lightened, as well as efficient parameterized analyses on the signal form and the conductor characteristics.

Abscesses can occur after appendectomy. With the increasing use of laparoscopy, this risk has increased in the same way as the incidence of abscesses related to dropped gallstones increased after laparoscopic cholecystectomy. However, this occurrence has been rarely reported. We describe here the case of a young patient who developed retroperitoneal abscess one year after laparoscopic appendectomy. [less ▲]

HIV infection remains a major problem of public health in Belgium as well as globally. The number of new diagnosies of HIV infection in Belgium remains between two and three daily. Given the dramatic effect of antiretroviral therapy on the mortality due to HIV infection, the number of patients is constantly increasing. The different problems related to HIV care are also changing. Aging of the patients and chronic exposure to antiretroviral medications have induced new complications. We will present in this brief article several new experimental and clinical approaches in which our centre has participated during the last two years. [less ▲]

Abstract To test whether a thymidine analog zidovudine (=AZT), is able to modify the radiosensitizing effects of (E)-2'-Deoxy-(fluoromethylene)cytidine (FMdC). A human colon cancer cell line Widr was exposed for 48 hours prior to irradiation to FMdC. Zidovudine was added at various concentrations immediately before irradiation. We measured cell survival and the effect of FMdC, AZT and FMdC + AZT on deoxynucleotide triphosphate pool. FMdC results in a significant increase of radiosensitivity. The enhancement ratios (ER =surviving fraction irradiated cells/surviving fraction drug treated and irradiated cells), obtained by FMdC or AZT alone are significantly increased by the combination of both compounds. Adding FMdC to AZT yields enhancement ratios ranging from 1.25 to 2.26. FMdC reduces dATP significantly, with a corresponding increase of TTP, dCTP and dGTP. This increase of TTP, dCTP and dGTP is abolished with the addition of AZT. Adding AZT to FMdC results in a significant increase of the radiosensitizing effect of FMdC. This combination appears to reduce the reactive enhancement of TTP, dCTP and dGTP induced by FMdC while it does not affect the inhibitory effect on dATP. [less ▲]

OBJECTIVES: The local mechanical environment influences early peri-implant tissue formation. It is still unclear whether immediate loading limits or promotes peri-implant osteogenesis and which mechanical parameters are important herein. The present study evaluated the influence of well-controlled mechanical stimuli on the tissue response around immediately loaded cylindrical turned titanium implants at two different observation periods. MATERIAL AND METHODS: A repeated sampling bone chamber, consisting of dual-structure perforated hollow cylinders with a cylindrical implant, was installed in the tibia of 14 rabbits and used to conduct three displacement-controlled immediate loading experiments: (i) 30 microm - 400 cycles/day - 1 Hz frequency - 2 x/week - 6 weeks; (ii) 30 microm - 400 cycles/day - 1 Hz - 2 x/week - 6 weeks, followed by another 6 weeks with a 50 microm - 800 cycles/day - 1 Hz - 2 x/week loading protocol; and (iii) 0 microm implant displacement for 12 weeks. A linear mixed model and logistic mixed model with alpha=5% were conducted on the data set. RESULTS: The tissue area fraction was significantly the highest after 12 weeks of loading. The bone area fraction was significantly different between all three loading conditions, with the highest values for the 12-week loading experiment. Twelve-week stimulation resulted in a significantly higher mineralized bone fraction than 6 weeks. Loading did have a significantly positive effect on the mineralized bone fraction. The incidence of osteoid-to-implant and bone-to-implant contact increased significantly when loading the implant for 12 weeks. CONCLUSION: Immediate loading had a positive effect on the tissue differentiation and bone formation around cylindrical turned titanium implants. Controlled implant micro-motion up to 50 microm had a positive effect on the bone formation at its interface. [less ▲]

Voltaire n'a pas ménagé le pays de Liège. État clérical, berceau de la Fête-Dieu, la principauté était symbolisée par l'Almanach de Mathieu Laensbergh, dont les prédictions entretenaient un fatalisme obscurantiste. Le présent ouvrage montre une réalité plus contrastée, où s'entrecroisent industrie de la contrefaçon littéraire, séjours d'écrivains en cavale et grandes entreprises typographiques, pour former une toile de fond sur laquelle se détache une véritable révolution des mentalités. L'impulsion fut-elle donnée par la création en 1756 du Journal encyclopédique? L'imprimeur Bassompierre avait-il auparavant ouvert la voie en publiant Diderot, l'École de la volupté du matérialiste La Mettrie ou le Code de la nature, sorte de charte pré-socialiste? Le règne de Charles d'Oultremont installe-t-il une parenthèse pieuse avant qu'apparaisse en 1772 son successeur Velbruck, franc-maçon et modèle de «prince-évêque éclairé»? Telles sont quelques-unes des questions discutées ici. Figurant parmi les capitales européennes de la contrefaçon du livre, Liège et sa filiale maastrichtoise participeront aux premières tentatives d'édition des oeuvres complètes des philosophes : Voltaire (en trente-deux volumes!), Helvétius, Montesquieu, Beaumarchais, Raynal. L'imprimeur Clément Plomteux se spécialisera dans d'ambitieux projets de totalisation du savoir, dont une refonte de l'Encyclopédie. La poésie, réveillée par le long séjour qu'effectue à Liège l'écrivain Léonard, stimulera l'idéal d'une régénération de l'homme par le retour à la nature. La Société Libre d'Émulation (1779) fournira la caisse de résonance que réclamaient un puissant souci collectif de modernité et l'avènement d'une «société des talents». S'y joignirent des revendications de justice sociale qui se lisent dans la littérature des procès opposant nobles et communautés, ou dans l'Histoire des deux Indes de Raynal et Diderot. L'«embrasement inévitable» de 1789 n'était plus loin. [less ▲]

L'objectif de ce travail est de se réapproprier la contribution de Heinrich Rickert au programme critique de fondation de l'ontologie. Il est apparu que cette contribution résidait dans l'analyse des structures formelles du jugement et, plus exactement, dans l'analyse du jugement existentiel. À la suite de Rickert, il a fallu déployer cette analyse sur deux versants: le versant noétique ou la théorie des actes judicatifs (Der Gegenstand der Erkenntnis, 1892-1928) et le versant noématique ou la théorie des propositions - ou "teneurs" - judicatives (Die Logik des Prädikats und das Problem der Ontologie, 1930). J'ai montré que cette double analyse permet non seulement de dégager deux concepts formels de l'être (l'être comme "Jaform" et comme "Urprädikat"), mais aussi de jeter les bases d'une théorie des catégories embrassant à la fois les étants sensibles et les étants non sensibles.

The erythrocyte, as an oxygen carrier, is submitted to areas where oxidative stress is important. The maintenance of the structure and fluidity of its membrane is essential to its function. Indeed, oxygen must diffuse through the membrane and the deformability of the cell is essential to its progression through capillaries. The structure and, as a consequence, the fluidity of the membrane influence these properties. The red blood cell presents antioxydant capacities, but in some cases, free radical production is increased and exceeds antiradical defences leading to irreversible defects of the membrane, and, as a consequence, of its function. Horse erythrocyte seems to be more sensitive to oxidative stress than other species and resulting hemorheological changes could have tissular and organic consequences. [less ▲]
