Numerical modelling of hydro‐mechanical behaviour of collapsible soils
Authors: Costa L. M. , Pontes I. D. S. , Guimarães L. J. N. , Ferreira S. R. M. 
Published: November 2007

AbstractThis paper presents a numerical simulation of the response of unsaturated soil under different loads, with special attention devoted to the phenomenon of pore collapse during wetting. A coupled hydro‐mechanical formulation, implemented in the computational code CODE_BRIGHT, is first presented. Then the model is applied to assess material parameter from laboratory tests and to simulate, as boundary value problems, new and appealing in situ tests designed in the Federal University of Pernambuco. The soil considered is a collapsible soil located in the semi‐arid region of the northeast of Brazil. Two situations are analysed: (i) the soil is initially at its natural water content and then flooded at some determined stress level, (ii) the soil is previously flooded and then loaded. Comparison between output results of numerical simulations and experimental data shows a very good agreement, which validate to some extent the proposed experimental procedure and the model formulation.

Space–time discontinuous Galerkin method for dynamics of solids
Authors: Aksoy H. G. , Şenocak E. 
Published: November 2007

AbstractIn this study, a space–time discontinuous Galerkin formulation is derived for dynamic analysis of solids. Numerical implementation of proposed formulation is presented, and numerical examples are provided for shock wave propagation problems. Numerical results are compared with that of the known exact solutions of the problems and numerical results obtained from a commercial finite element code. The proposed space–time discontinuous Galerkin formulation is found to be robust and successful in modelling transient problems, i.e. shock wave propagation problems.

Natural killer T cells and innate immune B cells from lupus‐prone NZB/W mice interact to generate IgM and IgG autoantibodies
Authors: Takahashi Tsuyoshi , Strober Samuel 
Published: November 2007

AbstractLupus‐prone NZB/W F1 mice develop glomerulonephritis after T helper cell‐dependent isotype switching of autoantibody secretion from IgM to IgG at about 6 months of age. We compared innate immune natural killer (NK) T cells and conventional T cells for their capacity to help spontaneous in vitro immunoglobulin and autoantibody secretion of innate immune (B‐1 and marginal zone) and conventional (follicular) B cell subsets from NZB/W F1 mice. We found that purified NKT cells not only increased spontaneous secretion of IgM and IgM anti‐double‐stranded (ds)DNA antibodies by B‐1 and marginal zone B cells, but also facilitated secretion of IgG anti‐dsDNA antibodies predominantly by B‐1 B cells. Few IgM or IgG anti‐dsDNA antibodies were secreted by follicular B cells, and conventional T cells failed to provide potent helper activity to any B cell subset. All combinations of T and B cell subsets from normal C57BL/6 mice failed to generate vigorous IgM and IgG secretion. NZB/W NKT cell helper activity was blocked by anti‐CD1 and anti‐CD40L mAb. In conclusion, direct interactions between innate immune T and B cells form a pathway for the development of IgM and IgG lupus autoantibody secretion in NZB/W mice.
