Euler-Lagrange Elasticity: Differential Equations for Elasticity without Stress or Strain  [PDF]
H. H. Hardy
Journal of Applied Mathematics and Physics (JAMP) , 2013, DOI: 10.4236/jamp.2013.17004
Abstract:

Differential equations to describe elasticity are derived without the use of stress or strain. The points within the body are the independent parameters instead of strain and surface forces replace stress tensors. These differential equations are a continuous analytical model that can then be solved using any of the standard techniques of differential equations. Although the equations do not require the definition stress or strain, these quantities can be calculated as dependent parameters. This approach to elasticity is simple, which avoids the need for multiple definitions of stress and strain, and provides a simple experimental procedure to find scalar representations of material properties in terms of the energy of deformation. The derived differential equations describe both infinitesimal and finite deformations.

New era in cancer immunotherapy: Twenty years to the discovery of monoclonal antibodies harnessing the immune system to eradicate tumors  [PDF]

Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.44A005
Abstract:

The better understanding of the mechanism in which the immune system responds to the developing cancer provided the outcome in a new era in cancer immunotherapy. The tumor suppressive effect on the immune system is caused by negative T cell receptor signaling that abrogate immunity against the cancer cells. Novel monoclonal antibodies that target co-inhibitory receptors on T cells block the tumor induced inhibition of the immune system and enable the immune system to eradicate the tumors. The development of such antibodies started twenty years ago by the preparation of a monoclonal antibody termed BAT. A single administration of the antibody to tumor bearing mice resulted in striking anti tumor activity that was mediated by the lymphocytes. These studies provided a basis for the new era of cancer immunotherapy. The present review summarizes twenty years to the discovery of monoclonal antibodies harnessing the immune system to eradicate tumors.

Euler-Lagrange Elasticity with Dynamics  [PDF]
H. H. Hardy
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.213138
Abstract: The equations of Euler-Lagrange elasticity describe elastic deformations without reference to stress or strain. These equations as previously published are applicable only to quasi-static deformations. This paper extends these equations to include time dependent deformations. To accomplish this, an appropriate Lagrangian is defined and an extrema of the integral of this Lagrangian over the original material volume and time is found. The result is a set of Euler equations for the dynamics of elastic materials without stress or strain, which are appropriate for both finite and infinitesimal deformations of both isotropic and anisotropic materials. Finally, the resulting equations are shown to be no more than Newton's Laws applied to each infinitesimal volume of the material.
Linear Algebra Provides a Basis for Elasticity without Stress or Strain  [PDF]
H. H. Hardy
Soft (Soft) , 2015, DOI: 10.4236/soft.2015.43003
Abstract: Linear algebra provides insights into the description of elasticity without stress or strain. Classical descriptions of elasticity usually begin with defining stress and strain and the constitutive equations of the material that relate these to each other. Elasticity without stress or strain begins with the positions of the points and the energy of deformation. The energy of deformation as a function of the positions of the points within the material provides the material properties for the model. A discrete or continuous model of the deformation can be constructed by minimizing the total energy of deformation. As presented, this approach is limited to hyper-elastic materials, but is appropriate for infinitesimal and finite deformations, isotropic and anisotropic materials, as well as quasi-static and dynamic responses.

Recherche et Pratiques Pédagogiques en Langues de Spécialité : Cahiers de l'APLIUT , 2012,
Abstract: Les dix textes publiés dans ce volume sur les supports filmiques au service de l’enseignement des langues étrangères traitent de films de cinéma, de séries télévisées, de documentaires, de courts métrages d’animation et de vidéos disponibles sur la toile. Quel que soit le support ou l’angle d’approche, ces différents médias visuels facilitent la construction des apprentissages linguistiques et culturels car ils captent l’attention et stimulent l’imagination. Surtout, ils offrent aux didac...

Recherche et Pratiques Pédagogiques en Langues de Spécialité : Cahiers de l'APLIUT , 2011,
Abstract: Ce volume des Cahiers est consacré aux actes du XXXIe Congrès de l’APLIUT qui s’est tenu à Dijon du 11 au 13 juin 2009. Les différentes contributions traitent de l’élaboration des dictionnaires, de leur contenu et de leur utilisation dans l’enseignement/apprentissage des langues vivantes. Il appara t clairement, au fil des textes, que les recherches récentes en lexicologie, sémantique, terminologie, analyse de discours, linguistique de corpus, etc., ont modifié profondément la dictionnairique...

Recherche et Pratiques Pédagogiques en Langues de Spécialité : Cahiers de l'APLIUT , 2011,
Abstract: Le présent volume des Cahiers ainsi que le prochain sont consacrés aux problématiques relatives à la phonétique et à la phonologie dans l’enseignement/apprentissage des langues de spécialité. Les quatre premiers articles concernent l’anglais, les trois suivants le fran ais langue étrangère (FLE). Tous soulignent que les difficultés rencontrées par les apprenants proviennent essentiellement d’interférences avec leur langue maternelle et proposent des pistes pour aider les apprenants à entend...
