    La saison s'annonce difficile pour l'équipe de foot féminine de Tottenham : avec leur terrain d'entraînement en rénovation, elles vont être obligées de partager celui des hommes. Alors qu'elles se battent déjà au quotidien pour être reconnues à leur juste valeur, elles devront en plus supporter les railleries de leurs homologues masculins ! 
    Pour Maja, la capitaine, cela ne fait que confirmer sa règle d'or : ne jamais sortir avec un joueur pro. De toute façon, elle ne correspond pas au cliché de la femme de footballeur ! Aucun risque de ce côté-là.
    Et pourtant, ne dit-on pas que les règles sont faites pour être brisées ?

  • The development of coherent radiation sources for sub-angstrom wavelengths - i.e. in the hard X-ray and gamma-ray range - is a challenging goal of modern physics. The availability of such sources will have many applications in basic science, technology and medicine and in particular, they may have a revolutionary impact on nuclear and solid state physics, as well as on the life sciences. The present state-of-the-art lasers are capable of emitting electromagnetic radiation from the infrared to the ultraviolet, while free electron lasers (X-FELs) are now entering the soft X-ray region. Moving further, i.e. into the hard X and/or gamma ray band, however, is not possible without new approaches and technologies.In this book we introduce and discuss one such novel approach -the radiation formed in a Crystalline Undulator - whereby electromagnetic radiation is generated by a bunch of ultra-relativistic particles channeling through a periodically bent crystalline structure. Under certain conditions, such a device can emit intensive spontaneous monochromatic radiation and even reach the coherence of laser light sources.Readers will be presented with the underlying fundamental physics and be familiarized with the theoretical, experimental and technological advances made during the last one and a half decades in exploring the various features of investigations into crystalline undulators. This research draws upon knowledge from many research fields - such as materials science, beam physics, the physics of radiation, solid state physics and acoustics, to name but a few. Accordingly, much care has been taken by the authors to make the book as self-contained as possible in this respect, so as to also provide a useful introduction to this emerging field to a broad readership of researchers and scientist with various backgrounds.This new edition has been revised and extended to take recent developments in the field into account. 

  • The classic Designing with Type has been completely redesigned, with an updated format and full color throughout. New information and new images make this perennial best-seller an even more valuable tool for anyone interested in learning about typography. The fifth edition has been integrated with a convenient website, www.designingwithtype.com, where students and teachers can examine hundreds of design solutions and explore a world of typographic information. First published more than thirty-five years ago, Designing with Type has sold more than 250,000 copies--and this fully updated edition, with its new online resource, will educate and inspire a new generation of designers.

  • Spanning two centuries, this collection documents the lives of fifteen remarkable Latinas who witnessed, defined, defied, and wrote about the forces that shaped their lives. As entrepreneurs, community activists, mystics, educators, feminists, labor organizers, artists and entertainers, Latinas used the power of the pen to traverse and transgress cultural conventions.

  • This book introduces readers to MesoBioNano (MBN) Explorer - a multi-purpose software package designed to model molecular systems at various levels of size and complexity. In addition, it presents a specially designed multi-task toolkit and interface - the MBN Studio - which enables the set-up of input files, controls the simulations, and supports the subsequent visualization and analysis of the results obtained. The book subsequently provides a systematic description of the capabilities of this universal and powerful software package within the framework of computational molecular science, and guides readers through its applications in numerous areas of research in bio- and chemical physics and material science - ranging from the nano- to the mesoscale.

    MBN Explorer is particularly suited to computing the system's energy, to optimizing molecular structure, and to exploring the various facets of molecular and random walk dynamics. The package allows the use of a broad variety of interatomic potentials and can, e.g., be configured to select any subset of a molecular system as rigid fragments, whenever a significant reduction in the number of dynamical degrees of freedom is required for computational practicalities. MBN Studio enables users to easily construct initial geometries for the molecular, liquid, crystalline, gaseous and hybrid systems that serve as input for the subsequent simulations of their physical and chemical properties using MBN Explorer.

    Despite its universality, the computational efficiency of MBN Explorer is comparable to that of other, more specialized software packages, making it a viable multi-purpose alternative for the computational modeling of complex molecular systems. A number of detailed case studies presented in the second part of this book demonstrate MBN Explorer's usefulness and efficiency in the fields of atomic clusters and nanoparticles, biomolecular systems, nanostructured materials, composite materials and hybrid systems, crystals, liquids and gases, as well as in providing modeling support for novel and emerging technologies.

    Last but not least, with the release of the 3rd edition of MBN Explorer in spring 2017, a free trial version will be available from the MBN Research Center website (mbnresearch.com).

  • This book introduces and reviews both theory and applications of polarizational bremsstrahlung, i.e. the electromagnetic radiation emitted during collisions of charged particles with structured, thus polarizable targets, such as atoms, molecules and clusters.
    The subject, following the first experimental evidence a few decades ago, has gained importance through a number of modern applications. Thus, the study of several radiative mechanisms is expected to lead to the design of novel light sources, operating in various parts of the electromagnetic spectrum. Conversely, the analysis of the spectral and angular distribution of the photon emission constitutes a new tool for extracting information on the interaction of the colliding particles, and on their internal structure and dynamical properties.
    Last but not least, accurate quantitative descriptions of the photon emission processes determine the radiative energy losses of particles in various media, thereby providing essential information required for e.g. plasma diagnostics as well as astrophysical and medical applications (such as radiation therapy).
    This book primarily addresses graduate students and researchers with a background in atomic, molecular, optical or plasma physics, but will also be of benefit to anyone wishing to enter the field.

  • Être joueur de football au sein d'un des plus grands clubs anglais n'est pas de tout repos. Cal Sparkles, 19 ans, ne dira pas le contraire : entraînements, restrictions alimentaires mais aussi fêtes et aventures d'un soir rythment son quotidien.
    Mais la vie de Cal est chamboulée lorsqu'il rencontre Gary Devlin, joueur prodige au physique de rêve. 
    Le doute commence à s'installer dans l'esprit de Cal, irrésistiblement attiré.... C'est le début d'un jeu dangereux entre les deux hommes.
