The authors present a novel lumped model for laminated cores considering the ID eddy current problem in a conducting ferromagnetic lamination. The model is based on a polynomial spatial expansion of the induction and the magnetic field throughout the thickness of the lamination, of order n and n + 2 respectively, such that the governing partial differential equation is satisfied (for any n greater than or equal to 0). The magnetic constitutive law is weakly imposed, leading to a system of 1 + n/2 nonlinear differential equations. The method is elaborated and validated for both the linear and the nonlinear case. A fast convergence towards the exact solution (n = infinity) is observed when increasing n. [less ▲]

Malgré des histoires et configurations coloniales hautement contrastées, des modèles sociétaux irréductibles, la situation belge s’inscrit à n’en pas douter dans les rails de l’« hiver impérial français » (Mbembe, 2010). La forte racialisation des personnes issues des ex-colonies afro-subsahariennes, le color-blindness étatique ou la marginalisation académique de la critique postcoloniale en sont les indicateurs majeurs. Pour autant, en Belgique, le modèle républicain, et ses prétentions universalistes, ne peut expliquer les dynamiques identitaires ni les imaginaires autochtones dont procède l’impensé de la race. Comme nous le verrons, la logique séparatiste d’une métropole en mal de légitimité impériale - qui dissocia avec force colonie et métropole et refusa de penser non seulement l’installation des Congolais en Belgique mais leur mobilité sociale - offre une lisibilité de la façon dont les frontières raciales informent, à date contemporaine, les anxiétés postcoloniales de l’autochtonie. Nous discuterons alors, à partir de données recueillies depuis une dizaine d’années au sein des milieux congolais, politiques, associatifs, religieux et artistiques, la façon dont la situation belge peut, ou pas, reformuler la particularité française sous l’angle d’une posture impériale francophone.

BACKGROUND AND METHODS: We studied the effect of volume resuscitation on lung fluid balance and systemic oxygen extraction during septic shock in eight anesthetized dogs. Sepsis was induced using a 2-hr continuous infusion of Escherichia coli endotoxin at 0.25 micrograms/min.kg. Relationships between oxygen uptake (VO2) and oxygen supply (DO2) were performed acutely during stepwise controlled decrements in cardiac output by progressive inflation of an intracardiac balloon. At each stage, DO2 and corresponding VO2 were measured independently and the individual critical DO2 level was referred to as the point below which the relationship held. The slope of such a constructed relationship was defined as the maximal oxygen extraction ratio. Lung fluid balance was assessed by measurements of extravascular lung water. All values were studied at baseline, after endotoxin insult, and after reversing hypotension by a 10% dextran infusion. RESULTS: Endotoxin infusion led to a shock state that associated hypotension (from 135 to 63 mm Hg) with increases in blood lactate (from 0.53 to 3.9 mmol/L). The mean critical DO2 and maximal oxygen extraction ratio were significantly altered from 7.9 to 17.8 mL/min.kg and from 0.81 to 0.38, respectively. After reversing hypotension by 28 mL/kg colloid infusion, the critical DO2 (11.4 mL/min.kg) and maximal oxygen extraction ratio (0.48) were significantly improved. However, restoration of normal values required a state of fluid overload by further dextran infusion (8 mL/kg). At the end of the fluid challenge, extravascular lung water significantly increased from 6.4 to 17.4 mL/kg. CONCLUSIONS: These data suggest that volume loading may reverse endotoxin-induced peripheral perfusion abnormalities. However, substantial pulmonary edema may occur, possibly jeopardizing the beneficial effects of fluid expansion. [less ▲]

Background Induced sputum is a non-invasive method to investigate airway inflammation, which has been used to assess pulmonary inflammatory diseases. However, this procedure has not been studied in the context of hematopoietic stem cell transplantation (HSCT). Methods We monitored lung function in 182 patients who underwent HSCT and measured airway inflammation by sputum induction in 80 of them. We prospectively measured FEV1, FVC, DLCO, KCO, TLC, RV, exhaled nitric oxide (FeNO) as well as sputum cell counts before and 3, 6, 12, 24 and 36 months after HSCT. Results For the whole cohort there was a progressive decrease in TLC, which was significant after 3 years (p < 0.01). By contrast, there was no change in other lung functions parameters or in FeNO. Baseline sputum analysis revealed increased neutrophil counts in patients {Median (IQR): 63% (38–79)} compared to healthy subjects matched for age {Median (IQR): 49% (17–67), p < 0.001} but there was no significant change in any type of sputum cell counts over the three years. When comparing myeloablative (MA) vs non-myeloablative (NMA) conditioning, falls in FEV1, FVC and DLCO, and rise in RV and sputum neutrophils were more pronounced over the first year of observation in those receiving MA. Conclusions There was a progressive loss in lung function after HSCT, featuring a restrictive pattern. Myeloablative conditioning was associated with early rise of sputum neutrophils and greater alteration in lung function over the first year. [less ▲]

Ozone is a well-known oxidant air pollutant, inhalation of which can result in oxidative stress, and lead to pulmonary inflammation. The aim of this study was to evaluate the time-course events after a single ozone exposure in transcription-coupled repair defective Csb and wild type mice. Mice were exposed for 3 h to 2 ppm ozone and biological parameters related to oxidative stress and inflammation were examined in the lungs at 0, 4, 9, 24 and 48 h after exposure. In addition the procoagulant and thrombomodulin activities were explored by a combination of assays for tissue factor and thrombin generation.This study revealed a significant biological response to ozone, for both Csb and wild type mice. The onset of inflammation in Csb mice, as indicated by an increase in interleukin-6, tumor necrosis factor-alpha and total cell influx, occurred earlier compared with those seen in wild type mice. On the other hand, Csb mice showed a delayed antioxidant reaction compared with wild type mice. Both genotypes developed a procoagulant reaction characterized by a stably increased tissue factor activity and a progressive increase in thrombin generation after 2 days.These experiments have shown that ozone, a well-known toxic substance from the environment, induces not only inflammation, but also procoagulant reactions in the lungs of mice. These results have implications for understanding the systemic effects induced by oxidant air pollutants. [less ▲]

The respiratory tract is continuously exposed to both innocuous airborne antigens and immunostimulatory molecules of microbial origin, such as LPS. At low concentrations, airborne LPS can induce a lung DC-driven Th2 cell response to harmless inhaled antigens, thereby promoting allergic asthma. However, only a small fraction of people exposed to environmental LPS develop allergic asthma. What prevents most people from mounting a lung DC-driven Th2 response upon exposure to LPS is not understood. Here we have shown that lung interstitial macrophages (IMs), a cell population with no previously described in vivo function, prevent induction of a Th2 response in mice challenged with LPS and an experimental harmless airborne antigen. IMs, but not alveolar macrophages, were found to produce high levels of IL-10 and to inhibit LPS-induced maturation and migration of DCs loaded with the experimental harmless airborne antigen in an IL-10-dependent manner. We further demonstrated that specific in vivo elimination of IMs led to overt asthmatic reactions to innocuous airborne antigens inhaled with low doses of LPS. This study has revealed a crucial role for IMs in maintaining immune homeostasis in the respiratory tract and provides an explanation for the paradox that although airborne LPS has the ability to promote the induction of Th2 responses by lung DCs, it does not provoke airway allergy under normal conditions.
