A subproblem technique is applied to dual thin shell finite element formulations. Both the magnetic vector potential and magnetic field formulations are considered. The subproblem approach developed herein couples three problems: a simplified model with only inductors, a thin region problem using approximate interface conditions and a correction problem to improve the accuracy of the thin shell approximation, in particular near their edges and corners. Each problem has its own geometry and is solved on its associated finite element mesh. [less ▲]

We address the problem of locating new facilities of a firm or franchise that enters a market where a competitor operates existing facilities. The goal of the new entrant firm is to decide the location and attractiveness of its new facilities that maximize its profit. The competitor can react by opening new facilities, closing existing ones, and adjusting the attractiveness levels of its existing facilities, with the aim of maximizing its own profit. The demand is assumed to be aggregated at certain points in the plane and the new facilities of both the firm and the competitor can be located at predetermined candidate sites. We employ the gravity-based rule in modeling the behavior of the customers where the probability that a customer visits a certain facility is proportional to the facility attractiveness and inversely proportional to the distance between the facility site and demand point. We formulate a bilevel mixed-integer nonlinear programming model where the firm entering the market is the leader and the competitor is the follower. We propose heuristics that combine tabu search with exact solution methods. [less ▲]

Introduction Un acide gras (AG) est un acide carboxylique avec une longue chaine aliphatique, qui peut être saturé ou insaturé. Récemment, le rôle des AG, particulièrement, celui des oméga-3 et oméga-6, a émergé comme facteur de risque cardiovasculaire dans la littérature. Le but de ce travail était de comparer les taux d’AG mesurés dans une population saine avec ceux obtenus chez des patients admis aux urgences pour un infarctus du myocarde. Matériels et méthodes Cinquante quatre sujets sains (33±11ans, 31 femmes) ont été sélectionnés comme population de référence. Ces derniers ont été sélectionnés selon leur mode de vie (alimentation, tabac, etc). En parallèle, nous avons dosé les AG chez 33 patients (55±9 ans, 12 femmes) admis dans le service d’urgence de notre institution pour infarctus aigu du myocarde (AMI). Le sang était prélevé sur EDTA. Avant l’analyse, les échantillons étaient lavés et transméthylés. Le dosage des AG était réalisé par chromatographie gazeuse couplée à un détecteur à ionisation de flamme (GCFID). Après le dosage, nous avons réalisés une comparaison des taux, sommes et rapport entre les différents AG ainsi que l’index oméga-3 (somme de l’acide eicosapentaénoïque et docosahexaénoïque) obtenus dans les 2 groupes. Résultats. Des valeurs de référence ont été obtenues pour notre population de référence via le logiciel de statistique MedCalc. Dans le groupe AMI, les taux d’oméga-6 étaient significativement plus élevés (p<0.05) pour C18:2n6 (Figure 1) et C18:3n6 (Figure 2)comparés aux résultats obtenus dans la population de référence. Par contre les taux d’oméga-3 étaient significativement plus bas (p<0.01) par rapport aux sujets de référence pour le C22 :6n3 (Figure 3). L’index oméga-3 montrait une valeur plus basse et le rapport oméga-6/oméga-3 était plus élevé dans le groupe AMI comparé aux sujets de référence. Conclusion Le dosage des AG est un nouvel outil que le laboratoire peut proposer aux cliniciens afin de stratifier les patients présentant le plus de risque cardiovasculaire avant ou après un infarctus du myocarde. Ces patients pourraient ainsi être supplémenté en acides gras oméga-3 afin d’éviter les récidives d’infarctus du myocarde ou de diminuer la formation de la plaque d’athérosclérose avant le premier accident.

The aim of this study was to determine results of kidney transplantation (KT) from controlled donation after cardio-circulatory death (DCD). Primary end-points were graft and patient survival, and post-transplant complications. The influence of delayed graft function (DGF) on graft survival and DGF risk factors were analyzed as secondary end-points. This is a retrospective mono-center review of a consecutive series of 59 DCD-KT performed between 2005 and 2010. Overall graft survival was 96.6%, 94.6%, and 90.7% at 3 months, 1 and 3 years, respectively. Main cause of graft loss was patient's death with a functioning graft. No primary nonfunction grafts. Renal graft function was suboptimal at hospital discharge, but nearly normalized at 3 months. DGF was observed in 45.6% of all DCD-KT. DGF significantly increased postoperative length of hospitalization, but had no deleterious impact on graft function or survival. Donor body mass index >/=30 was the only donor factor that was found to significantly increase the risk of DGF (P < 0.05). Despite a higher rate of DGF, controlled DCD-KT offers a valuable contribution to the pool of deceased donor kidney grafts, with comparable mid-term results to those procured after brain death.

Within the framework of policies to promote the diversity, the use of quota is more and more discussed, what besides brings to the foreground tensions about this issue. There is no uniform model about that in the European countries. This article realizes an inventory of fixtures, in Belgium and in France, on the laws concerning the usage of the quota and the arguments (positive and negatives) in this issue. This research participates to show that the development of the quote in Europe joins in the passage of a regulation " soft law " towards one " hard law ". [less ▲]

Estimating the orientation of the observed person is a crucial task for home entertainment, man-machine interaction, intelligent vehicles, etc. This is possible but complex with a single camera because it only provides one side view. To decrease the sensitivity to color and texture, we use the silhouette to infer the orientation. Under these conditions, we show that the only intrinsic limitation is to confuse the orientation q with the supplementary angle (that is 180°-theta), and that the shape descriptor must distinguish between mirrored images. In this paper, the orientation estimation is expressed and solved in the terms of a regression problem and supervised learning. In our experiments, we have tested and compared 18 shape descriptors; the best one achieves a mean error of 5:24°. However, because of the intrinsic limitation mentioned above, the range of orientations is limited to 180°. Our method is easy to implement and outperforms existing techniques. [less ▲]

Organic dust contains pathogen-associated molecular patterns (PAMPs) which can induce significant airway diseases following chronic exposure. Mononuclear phagocytes are key protecting cells of the respiratory tract. Several studies have investigated the effects of PAMPs and mainly endotoxins, on cytokine production. However the sub-lethal cytotoxicity of organic dust components on macrophages has not been tested yet. The novel technology of high content analysis (HCA) is already used to assess subclinical drug-induced toxicity. It combines the capabilities of flow cytometry, intracellular fluorescence probes, and image analysis and enables rapid multiple analyses in large numbers of samples. In the present study, HCA was used to investigate the cytotoxicity of the 3 major PAMPs contained in organic dust, ie. endotoxin (LPS), peptidoglycan (PGN) and β-glucans (zymosan) on THP-1 monocyte-derived macrophages. LPS was used at concentrations of 0.005, 0.01, 0.02, 0.05, 0.1 and 1 μg/ml; PGN and zymosan were used at concentrations of 1, 5, 10, 50, 100 and 500 μg/ml. Cells were exposed to PAMPs for 24 h. In addition, the oxidative burst and the phagocytic capabilities of the cells were tested. An overlap between PGN intrinsic fluorescence and red/far-red fluorescent dyes occurred, rendering the evaluation of some parameters impossible for PGN. LPS induced sub-lethal cytotoxicity at the lowest dose (from 50 ng/ml). However, the greatest cytotoxic changes occurred with zymosan. In addition, zymosan, but not LPS, induced phagosome maturation and oxidative burst. Given the fact that β-glucans can be up to 100-fold more concentrated in organic dust than LPS, these results suggest that β-glucans could play a major role in macrophage impairment following heavy dust exposure and will merit further investigation in the near future.

Concrete is a complex composite material. Hence, the main components of concrete on meso-scale should be considered when studying its global elastic properties. As a main ingredient of concrete, aggregate will exert influences on the elastic properties of concrete. In the present study, particularly particle shape and particle packing are considered of relevance. The densely packed structure of arbitrary shaped aggregate is simulated by a concurrent algorithm-based discrete element modelling (DEM) system. A comparison is pursued of data, produced by numerical models, either based on arbitrary angular-shaped particles or on spherical ones. This will be accomplished by means of the finite element method (FEM). The results can be used to evaluate the adequacy for this purpose of conventional numerical or analytical models based on spherical aggregates. The influences exerted on the elastic properties of concrete by other factors, such as the mechanical and physical properties of the aggregate, the ITZ and the matrix will also be addressed in this study.

Although Bharati Mukherjee is famous, or rather infamous, for her shameless embrace of America and its melting-pot ideology, in Desirable Daughters India, the homeland, is unexpectedly made to re-enter the stage of immigrant identity construction. In many respects it would seem that it has now become untenable to represent immigrant identity in terms of a one-directional movement from “India” to “America.” In Desirable Daughters the rise of India, the accelerated time/space compression of late capitalism, the post-90s paradigm shift in matters of transnational migration, the emphasis on return migrations and the emergence of a new global interaction indeed dramatically outflank Mukherjee’s previous narrative of American “exceptionalism” – which suddenly seems dated by comparison. By portraying the complex transnational network of connections operating between RIs (Resident Indians) and NRIs (Non Resident Indians), Mukherjee’s book gestures towards the “de-spatialization” of immigrant identity construction and its consequent “re-metaphorization” in terms of “time zones.” What is more, the increasingly compelling influence of contemporary India on the Indo-American diasporic subjectivity marks a “back to the future” return of the repressed which temporally repositions migrant identity between a ghostly time of repetition and a “hauntology” of new becomings. What Mukherjee suggests, I will contend, is that immigrant agency and self-fashioning cannot be associated anymore with the “pioneering spirit” of forward-looking characters that discard their “Indianness” upon (geographical) entry into the West. In my reading of Desirable Daughters the protagonist’s zigzagging path to self-transformation will be emphasized, so that it will become apparent that time has become the fourth space through which new spaces for diasporic identity can be renegotiated.
