In Italia le bollette sono tra le più care d'Europa. È la dipendenza dall'estero a condannarci, come se dalla crisi energetica non avessimo imparato nulla. Eppure, sappiamo che il fossile è responsabile dello sconvolgimento climatico. E che liberarsi di gas, petrolio e carbone è l'unico modo per risanare il pianeta e il nostro portafogli. Ma su quali fonti conviene investire? Se c'è un tema che lascia interdetti è proprio quello dell'energia. Le questioni sono tante e chi ha interessi in gioco non fa che confondere le acque.

Starlet ha diciassette anni, i capelli viola e vive a Riccione. È un'estate degli anni novanta «veloce e immortale», e lei e i suoi amici si aggirano per viale Ceccarini esibendo bizzarre acconciature, ciglia metallizzate e scarpe Buffalo con la para altissima, davanti allo sguardo scandalizzato delle famiglie in vacanza. Starlet, Nina, Moni e Edie abitano in una specie di futuro marzianeggiante e policromatico, un Cabaret Voltaire a cielo aperto parecchio distante dal piattume attuale: un futuro che non sarebbe mai arrivato - e che, come questo libro ormai mitologico racconta, sembra aver raggiunto in quegli anni l'apice della propria espressività.

Questa è la storia di Demon e Davi, diciottenni celestiali e perverse che vivono al contrario. Dormono di giorno e si svegliano di notte, come pipistrelli; lavorano in un night club di Zurigo e assumono il Luminal, potente e leggendario barbiturico con il quale, si dice, sia morta Marilyn Monroe. Sui loro corpi esili ed eterei, che pattinano flessuosamente per le strade gelate, c'è sempre la luna, «così appesa sopra un concerto di David Bowie», centro ipnotico e madre che le ha partorite lasciandole cadere dall'alto.

All'uscita di questo libro, nel 1996, Alessandro Baricco scrisse: «Meglio se le vostre cellule cerebrali non hanno più di quarant'anni, se no rischiate di scivolarci sopra come una mano su una grattugia». È la storia di Misty, una venticinquenne che si trasferisce dall'Adriatico a Londra per prestare strani servizi a domicilio, praticando voyeurismo con uomini e donne esibizionisti. Si veste di tulle, latex e «tacchi a spillo blu codeina», beve collutorio e si annichilisce platealmente nelle esperienze più estreme - ma anche nel tumulto di una cultura anarchica e antagonista, tra un disco di Courtney Love, un manga, un anime e una sigaretta francese.

Solid Mechanics: A Variational Approach, Augmented Edition presents a lucid and thoroughly developed approach to solid mechanics for students engaged in the study of elastic structures not seen in other texts currently on the market. This work offers a clear and carefully prepared exposition of variational techniques as they are applied to solid mechanics. Unlike other books in this field, Dym and Shames treat all the necessary theory needed for the study of solid mechanics and include extensive applications. Of particular note is the variational approach used in developing consistent structural theories and in obtaining exact and approximate solutions for many problems. Based on both semester and year-long courses taught to undergraduate seniors and graduate students, this text is geared for programs in aeronautical, civil, and mechanical engineering, and in engineering science. The authors’ objective is two-fold: first, to introduce the student to the theory of structures (one- and two-dimensional) as developed from the three-dimensional theory of elasticity; and second, to introduce the student to the strength and utility of variational principles and methods, including briefly making the connection to finite element methods. A complete set of homework problems is included.

This textbook offers an introduction to modeling the mechanical behavior of solids within continuum mechanics and thermodynamics. To illustrate the fundamental principles, the book starts with an overview of the most important models in one dimension. Tensor calculus, which is called for in three-dimensional modeling, is concisely presented in the second part of the book. Once the reader is equipped with these essential mathematical tools, the third part of the book develops the foundations of continuum mechanics right from the beginning. Lastly, the book’s fourth part focuses on modeling the mechanics of materials and in particular elasticity, viscoelasticity and plasticity. Intended as an introductory textbook for students and for professionals interested in self-study, it also features numerous worked-out examples to aid in understanding.

The theory of center manifold reduction is studied in this monograph in the context of (infinite-dimensional) Hamil- tonian and Lagrangian systems. The aim is to establish a "natural reduction method" for Lagrangian systems to their center manifolds. Nonautonomous problems are considered as well assystems invariant under the action of a Lie group ( including the case of relative equilibria). The theory is applied to elliptic variational problemson cylindrical domains. As a result, all bounded solutions bifurcating from a trivial state can be described by a reduced finite-dimensional variational problem of Lagrangian type. This provides a rigorous justification of rod theory from fully nonlinear three-dimensional elasticity. The book will be of interest to researchers working in classical mechanics, dynamical systems, elliptic variational problems, and continuum mechanics. It begins with the elements of Hamiltonian theory and center manifold reduction in order to make the methods accessible to non-specialists, from graduate student level.

In this book, we give a rational treatment of multicomponent materials as intera- ingcontinua.Weoffertwoderivationsoftheequationsofmotionfortheinteracting continua; one which uses the concepts of continua for the components, and one which applies an averaging operation to the continuum equations for each c- ponent. Arguments are given for constitutive equations appropriate for dispersed multicomponent ?ow. The forms of the constitutive equations are derived from the principles of continuum mechanics applied to the components and their int- actions. The solutions of problems of hydromechanics of ordinary continua are used as motivation for the forms of certain constitutive equations in multicom- nent materials. The balance of the book is devoted to the study of problems of hydrodynamics of multicomponent ?ows. Many materials are homogeneous in the sense that each part of the material has the same response to a given set of stimuli as all of the other parts. An example of such a material is pure water. Formulation of equations describing the behavior of homogeneous materials is well understood, and is described in numerous standard textbooks. Many other materials, both manufactured and occurring in nature, are not - mogeneous. Such materials are often given names such as mixtures or composites.

Molecular Theory of Solvation presents the recent progress in the statistical mechanics of molecular liquids applied to the most intriguing problems in chemistry today, including chemical reactions, conformational stability of biomolecules, ion hydration, and electrode-solution interface. The continuum model of "solvation" has played a dominant role in describing chemical processes in solution during the last century. This book discards and replaces it completely with molecular theory taking proper account of chemical specificity of solvent.
