This paper deals with the use of eXtended Finite Element Method (XFEM) to perform local effects in three-dimensional reinforced composites. This method was first introduced to model cracks. It is based on the partition of unity concept and the description of discontinuities like the location of holes and material interfaces is often realized by the level-set method. The approach considered allows (i) to easily model the real geometry of reinforcing fibers (not idealized), (ii) to impose arbitrary Dirichlet and Neumann boundary conditions on the implicit defined boundaries and (iii) to introduce models of degradation. Numerical applications are presented on some academic tests. [less ▲]

This paper presents some extensions of flexible multibody formalisms for mechatronic applications. The software implementation is realized in a general purpose finite element code, and three specific subjects are discussed: (i) nonlinear model reduction techniques for flexible multibody systems, (ii) integrated modelling of mechatronic systems, (iii) time-integration algorithms for coupled problems. The relevance of those developments are demonstrated for the dynamic analysis and the control design of an experimental lightweight manipulator. [less ▲]

We present several types of extended formulations for integer programs, based on irreducible integer solutions to Gomory’s group relaxations. We present algorithmic schemes based on an iterative reformulation technique using these extended formulations. We give computational results for benchmark problems, which illustrate the primal and dual effect of the reformulation. [less ▲]

The effective thermal conductivity of nanocomposites constituted by nanoparticles and homogeneous host media is discussed from the point of view of extended irreversible thermodynamics. This formalism is particularly well adapted to the description of small length scales. As illustrations, dispersion of Si nanoparticles in Ge (respectively, SiO2 in epoxy resin) homogeneous matrices is investigated, the nanoparticles are assumed to be spherical with a wide dispersion. Four specific problems are studied: the dependence of the effective thermal conductivity on the volume fraction of particles, the type of phonon scattering at the interface particle-matrix, the radius of the nanoparticles and the temperature. © 2015 The Author(s) Published by the Royal Society.

We previously reported data from 103 patients with hematologic malignancies (median age 54 years) who received peripheral blood stem cell (PBSC) grafts from HLA-matched unrelated donors after nonmycloablative conditioning and were given postgrafting immunosuppression consisting of mycophenolate mofetil (MMF; administered from day 0 until day + 40 with taper through day + 96) and cyclosporine (CSP; given from day -3 to day + 100, with taper through day 180) (historical patients). The incidences of grade II-IV acute and extensive chronic graft-versus-host disease (aGVHD, cGVHD) were 52% and 49%, respectively, and the 1-year probabilities of relapse, nonrelapse mortality (NRM), and progression-free survival (PFS) were 26%, 18%, and 56%, respectively. Here, we treated 71 patients with hematologic malignancies (median age 56 years) with unrelated PBSC grafts and investigated whether postgrafting immunosuppression with an extended course of NMF, given at full dosing until day + 150 and then tapered through day + 180, and a shortened course of CSP, through day + 80, would promote tolerance induction and reduce the incidence of GVHD (current patients). We observed 77% grade ll-1V aGVHD and 45% extensive cGVHD (P =.03, and P =.43, respectively, in current compared to historical patients). The 1-year probabilities of relapse, NRM, and PFS were 23%, 29%, and 47%, respectively (P =.89, P =.02, and P =.08 compared to the historical patients). We conclude that postgrafting immunosuppression with extended MMF and shortened CSP failed to decrease the incidence of GVHD among unrelated PBSC recipients given nonmyeloablative conditioning.

Extended spectrum beta-lactamases (ESBL)-producing Escherichia coli have emerged worldwide in animal husbandry and they were reported from different ecosystems. The purpose of this study was firstly, to investigate the presence of ESBL-producing E. coli in the gastrointestinal (GIT) and reproductive (RT) tracts of broiler breeding roosters, and secondly to study the impact of an ESBL-producing E. coli on artificially infected semen. A total of seventeen ESBL-producing E. coli strains were isolated from the gastrointestinal and reproductive tracts of nine broiler breeding roosters. All isolates were identified to the species level by API 20E system and MALDI-TOF, serotyped, and genetically characterized for ESBL production. Semen was artificially infected with E. coli ATCC25922 or with an ESBL-producing E. coli strain recovered from the reproductive tract. A computer aided semen analyzer (CASA) was used to compare different spermatozoa motility parameters in each sample. All ESBL-producing E. coli isolates could not be typed with the currently used sera and they were harboring a blaCTX-M gene alone or in combination with a blaTEM gene. The semen quality was notably less affected in samples infected with ESBL-producing E. coli strain compared to the control and sample infected with E. coli ATCC25922. The present study revealed that ESBL-producing E. coli can be isolated from both reproductive and digestive tracts of broiler breeding roosters. Contamination of the reproductive tract with ESBL-producing E. coli could lead to contamination of semen and could be an important factor in the dissemination of ESBL-producing E. coli in poultry.

A new mathematical model is developed, describing size-dependent subcontinuum thermoelectric properties from an extended thermodynamic point of view. This model takes into account the non-local effects of heat transfer through phonons and electrons that are important at nanometric scales. These phenomena are extended to apply also for electric transfer as well as the Seebeck coefficient. This model includes at nanoscale size-dependent electron and phonon thermal conductivities, electric conductivity, Seebeck coefficient and carrier concentrations. We compared nanofilms to nanocomposites and assessed their thermoelectric performances in the form of a figure of merit using as an example Bismuth and BismuthTelluride materials. It appeared that the figure of merit increases considerably for nanofilms and nanocomposites with respect to bulk materials. This is caused by the scattering of phonons and electrons. Our model shows that this scattering effect is not only present at the boundary or particle-matrix interface of the nanosized material, but also within it. The effect of particle size and surface specularity has been investigated, showing that a decreasing value of the particle size and specularity increases the scattering effect and improves the thermoelectric properties. An extension towards thin films of nanocomposite has been presented. © 2015. [less ▲]
