A multiscale method is developed to study the failure of carbon fiber reinforced composites. In order to capture the intra-laminar failure, a non-local mean-field homogenization (MFH) method accounting for the damage evolution of the matrix phase of the composite material [1] is considered. In that formulation, an incremental-secant MFH approach is used to account for the elastic unloading of the fibers during the strain softening of the matrix. In order to avoid the strain/damage localization caused by the matrix material softening, an implicit non-local method [2] was reformulated to account for the composite material anisotropy. As a result, accurate predictions of the composite softening behavior and of the different phases response is possible, even for volume ratios of inclusions around 60%. In particular it is shown that the damage propagation direction in each ply follows the fiber orientation in agreement with experimental data. The delamination process is modeled by recourse to a hybrid discontinuous Galerkin (DG)/ extrinsic cohesive law approach. As for the extrinsic cohesive law (ECL), which represents the fracturing response only, and for which cohesive elements are inserted at failure onset, the method does not suffer from a mesh-dependent effect. However, because of the underlying discontinuous Galerkin method, interface elements are present since the very beginning of the simulation avoiding the need to propagate topological changes in the mesh with the propagation of the delamination. Moreover, the pre-failure response is accurately captured by the material law though the DG implementation, by contrast to usual intrinsic cohesive laws. As a demonstration of the efficiency and accuracy of the method, a composite laminate with a quasi-isotropic sequence ([90/45/-45/90/0]S) and an open-hole geometry is studied using the multiscale method [3] and the results are compared to experimental data. The numerical model is found to predict the damage bands along the fiber directions as observed in the experimental samples inspected by X-ray computed tomography (XCT). Moreover, the predicted delamination pattern is found to match the experimental observations. REFERENCES [1] L. Wu, L. Noels, L. Adam, I.

Two women, aged 44 and 29 years, respectively, were admitted to the hospital in early 1987 for recurrent pneumothorax, dyspnea and a diffuse reticulonodular pattern evidenced on the chest x-ray film. Lung biopsy confirmed LAM in both patients. Both were treated sequentially with medroxyprogesterone and a LHRH agonist (buserelin) to achieve reversible medical castration. Neither subjective nor objective improvement was noted after 13 and 5 months, respectively, of buserelin therapy (900 micrograms/day, nasal spray) despite an effective suppression of the pituitary-gonadal axis. Medroxyprogesterone also was ineffective. Buserelin thus failed to control pulmonary LAM in these two patients, in spite of effective medical castration. [less ▲]

A practical methodology has been developed for predicting flows generated by dam failures or malfunctions in a complex or a series of dams. A twofold approach is followed. First, the waves induced in the downstream reservoirs are computed, as well as hydrodynamic impacts induced on downstream dams and dikes are estimated. Second, the flood wave propagation and the inundation process are simulated in the downstream valley, accounting for possible dam collapse or breaching in cascade. Two complementary flow models are combined: a two-dimensional fully dynamic model and a simplified lumped model. At each stage, the methodology provides guidelines to select the most appropriate model for efficiently computing the induced flows. Both models handle parametric modeling of gradual dam breaching. The procedure also incorporates prediction of breach formation time and final width, as well as sensitivity analysis to compensate for the high uncertainties remaining in the estimation of breach parameters. The applicability of the modeling procedure is demonstrated for a case study involving a 70m-high gravity concrete dam located upstream of four other dams. [less ▲]

We investigated in a preclinical canine model of hematopoietic cell transplantation (HCT) whether preemptive donor lymphocyte infusion (DLI) given 1 month after HCT could prevent late graft rejection that was the rule in historical dogs given suboptimal conditioning with 1 Gy of total body irradiation (TBI) before and immunosuppression with cyclosporine (CSP) and either mycophenolate mofetil (MMF; n = 6) or rapamycin (n = 5) after dog leukocyte antigen (DLA)-identical marrow transplantation. Nine dogs given DLA-identical marrow after I Gy of TBI followed by postgrafting MMF and CSP were studied. A single DLI was given 28-36 days after HCT, either with (n = 5) or without (n = 4) preceding treatment with the immunosuppressive drug pentostatin. Two of the 4 dogs given DLI only maintained stable mixed donor-host chimera beyond 30 weeks after HCT, whereas 2 rejected their grafts, on weeks 10 and 15 after HCT. One of the 5 dogs given pentostatin before DLI maintained a stable mixed donor-host chimera beyond 30 weeks, whereas 4 rejected their grafts, at weeks 8, 12, 12, and 16 after HCT. The 30-week probability of stable mixed chimerism, was 33% among dogs given DLI, versus 0% among 11 historical dogs (P = .003). In conclusion, DLI was only moderately effective in preventing graft rejection in this model. Additional immunosuppression with pentostatin did not improve that outcome. The model might be useful in developing potential strategies aimed at preventing graft rejection in patients with low donor chimerism, levels.

Divergent results have been reported on the effects of lipopolysaccharides (LPS) on the activation of equine polymorphonuclear leukocytes (PMN). We therefore attempted to determine whether LPS alone can stimulate equine PMN or whether plasma factors are necessary. PMN were isolated from citrated blood on a discontinuous density gradient of Percoll. The luminol (10(-3) mol/L)-enhanced chemiluminescence (CL) of 1.25 x 10(6) cells was measured after addition of Escherichia coli LPS (0.001-10 micrograms/ml) alone or after incubation in autologous plasma (1 h, 37 degrees C). After direct stimulation with LPS, there were random variations of CL in 16 horses that were not reproducible from one sample to the next for the same horse. LPS which had been incubated in plasma gave a dose-dependent stimulation of the CL of the PMN, which did not occur if the plasma had been heat inactivated (1 h, 56 degrees C). These results indicated a role for plasma factors, which were unlikely to be cytokines, as there were no monocytes or lymphocytes in the plasma incubated with LPS, but might have been complement fragments or LPS ligands, such as LPS binding protein. Studies using specific antibodies against these factors are needed to clarify this question. [less ▲]

Financial indicators have been widely used in the business failure literature in order to predict the risk of failure of firms (Beaver, 1966; Altman, 1968; Barnes, 1987; Aziz et al., 1988). In contrast, financial ratios have been less commonly used in a more preventive perspective to failure (Van Wymeersch and Wolfs, 1996; Van Caillie, 2000; Balcaen and Ooghe, 2006). Nevertheless, in a preventive perspective to small business failure, it is important to better understand how financial symptoms combine over time (Ooghe and Van Wymeersch, 1986) and to identify if relationships can be traced between the fundamental causes of failure and specific financial indicators. Considering this last statement and with reference to the explanatory business failure patterns (EBFPs) identified by Crutzen (2009) amongst a sample of small firms, this paper tests a series of hypotheses which aim at determining if these (causal) patterns can be associated with some specific financial indicators and, if so, if small distressed firms can be associated to one particular EBFP on the basis of the financial information published in the annual accounts. If each EBFP leads to some specific financial symptoms, then it will be possible to get a proxy information about the fundamental problems inducing failure without having any access to internal information, this identification being considered as a crucial step in the elaboration of any recovery or takeover plan (Argenti, 1976; Gaskill et al., 1993).

The problem of columns submitted to fire is discussed in the intoduction with an emphasis on the differences between the case of a column acting as a single element or being part of a frame. In the latter case, failure of the column does not necessarily lead to the failure of the structure. The basic principles of the arc-length technique are given, first for the way it is applied traditionally at room temperature, then for the way it can be applied to extend a numerical simulation beyond the moment of local failures in case of fire. The technique is then applied to the case of restrained columns and it is shown how it is possible to obtain a safe estimate of the critical temperature of the column leading to the failure of the structure, even if the degree of restraint apllied to the column is unknown.
