    Dans le courant de l’année 2010, un dépôt d’objets métalliques datés de la fin de l’âge du Bronze final a été découvert au lieu-dit « la Chapelle des Roches » en la commune du Châtellier dans l’Orne. La parcelle concernée se situe au sein d’un environnement particulier, puisqu‘il s’agit d’un promontoire rocheux, formant un petit éperon dominant le cours de La Varenne d’une cinquantaine de mètres. La découverte se présentait sous la forme d’un regroupement de soixante-quinze objets contenus da..

    A one point integration rule over star convex polytopes

    In this paper, the recently proposed linearly consistent one point integration rule for the meshfree methods is extended to arbitrary polytopes. The salient feature of the proposed technique is that it requires only one integration point within each n-sided polytope as opposed to 3n in Francis et al. (2017) and 13n integration points in the conventional approach for numerically integrating the weak form in two dimensions. The essence of the proposed technique is to approximate the compatible strain by a linear smoothing function and evaluate the smoothed nodal derivatives by the discrete form of the divergence theorem at the geometric center. This is done by Taylor's expansion of the weak form which facilitates the use of the smoothed nodal derivatives acting as the stabilization term. This translates to 50% and 30% reduction in the overall computational time in the two and three dimensions, respectively, whilst preserving the accuracy and the convergence rates. Th

    Bioethical and juridical aspects of transsexualism

    O transexualismo tem sido muito discutido atualmente, tanto na área médica como jurídica. Diferentes aspectos relativos à readequação sexual dos portadores de transexualismo estão envolvidos nesta discussão, enfatizando-se, sobretudo, o direito à identidade sexual, que é um direito fundamental. Em 1997, o Conselho Federal de Medicina editou uma Resolução que estabelece critérios diagnósticos de transexualismo e critérios para a realização da cirurgia de transgenitalização. A cirurgia é uma das etapas do processo de readequação sexual.Currently, transsexualism is a widely discussed matter in both the fields of medicine and law. This discussion involves different aspects related to the sexual readaptation of carriers of transsexualism, with special emphasis on the right to sexual identity, which is a fundamental right. In 1997, the Federal Council of Medicine of Brazil passed a resolution establishing diagnostic criteria for transsexualism and for the carrying out of surgery for sex reassignment. The surgery is one of the steps of the process of sexual readaptation

    A new one point quadrature rule over arbitrary star convex polygon/polyhedron

    Get PDF
    The Linear Smoothing (LS) scheme \cite{francisa.ortiz-bernardin2017} ameliorates linear and quadratic approximations over convex polytopes by employing a three-point integration scheme. In this work, we propose a linearly consistent one point integration scheme which possesses the properties of the LS scheme with three integration points but requires one third of the integration computational time. The essence of the proposed technique is to approximate the strain by the smoothed nodal derivatives that are determined by the discrete form of the divergence theorem. This is done by the Taylor's expansion of the weak form which facilitates the evaluation of the smoothed nodal derivatives acting as stabilization terms. The smoothed nodal derivatives are evaluated only at the centroid of each integration cell. These integration cells are the simplex subcells (triangle/tetrahedron in two and three dimensions) obtained by subdividing the polytope. The salient feature of the proposed technique is that it requires only nn integrations for an nn- sided polytope as opposed to 3n3n in~\cite{francisa.ortiz-bernardin2017} and 13n13n integration points in the conventional approach. The convergence properties, the accuracy, and the efficacy of the LS with one point integration scheme are discussed by solving few benchmark problems in elastostatics.

    Chaste: a test-driven approach to software development for biological modelling

    Get PDF
    Chaste (‘Cancer, heart and soft-tissue environment’) is a software library and a set of test suites for computational simulations in the domain of biology. Current functionality has arisen from modelling in the fields of cancer, cardiac physiology and soft-tissue mechanics. It is released under the LGPL 2.1 licence.\ud \ud Chaste has been developed using agile programming methods. The project began in 2005 when it was reasoned that the modelling of a variety of physiological phenomena required both a generic mathematical modelling framework, and a generic computational/simulation framework. The Chaste project evolved from the Integrative Biology (IB) e-Science Project, an inter-institutional project aimed at developing a suitable IT infrastructure to support physiome-level computational modelling, with a primary focus on cardiac and cancer modelling

    Chaste: an open source C++ library for computational physiology and biology

    Get PDF
    Chaste - Cancer, Heart And Soft Tissue Environment - is an open source C++ library for the computational simulation of mathematical models developed for physiology and biology. Code development has been driven by two initial applications: cardiac electrophysiology and cancer development. A large number of cardiac electrophysiology studies have been enabled and performed, including high performance computational investigations of defibrillation on realistic human cardiac geometries. New models for the initiation and growth of tumours have been developed. In particular, cell-based simulations have provided novel insight into the role of stem cells in the colorectal crypt. Chaste is constantly evolving and is now being applied to a far wider range of problems. The code provides modules for handling common scientific computing components, such as meshes and solvers for ordinary and partial differential equations (ODEs/PDEs). Re-use of these components avoids the need for researchers to "re-invent the wheel" with each new project, accelerating the rate of progress in new applications. Chaste is developed using industrially-derived techniques, in particular test-driven development, to ensure code quality, re-use and reliability. In this article we provide examples that illustrate the types of problems Chaste can be used to solve, which can be run on a desktop computer. We highlight some scientific studies that have used or are using Chaste, and the insights they have provided. The source code, both for specific releases and the development version, is available to download under an open source Berkeley Software Distribution (BSD) licence at http://www.cs.ox.ac.uk/chaste, together with details of a mailing list and links to documentation and tutorials

    Port-en-Bessin-Huppain, Commes – Le Mont Castel

    Depuis quatre ans, le site du Mont Castel fait l’objet de fouilles archéologiques programmées à la fin de l’été. En 2018 la fouille a concerné l’étude d’un vaste horreum et l’étude des abords du rempart, à proximité de l’habitat de l’âge du Bronze. C’est dans ce secteur qu’a été mis au jour, en début de campagne, un dépôt du Bronze final 3a comportant une trentaine d’objets en bronze dans un vase en céramique. Ce dépôt est une découverte de premier plan au niveau national puisque intègre et e..
