Over the last two decades, obesity has reached epidemic proportions in the world, resulting in suffering and premature death. Morbid obesity is a chronic medical illness that has long-reaching consequences and is caused by multiple factors. Bariatric surgery and other non-invasive procedures in carefully selected patients are effective treatments for obesity. It is the only tool for sustained and effective long-term weight loss. The field of surgery is developing rapidly offering innovative options for patients who have failed to lose weight by diet, exercise and pharmacological methods. The editors review problems that the patients face in the perioperative period and in the long term, as well as their adjustments in lifestyle and healthcare management. The text is authored by authorities who participate in the multidisciplinary care of bariatric patients. It will address the assessment and selection of patients' treatment before surgery, options for surgical intervention and postoperative medical management.
This is a short tract on the essentials of differential and symplectic geometry together with a basic introduction to several applications of this rich framework: analytical mechanics, the calculus of variations, conjugate points & Morse index, and other physical topics. A central feature is the systematic utilization of Lagrangian submanifolds and their Maslov-Hörmander generating functions. Following this line of thought, first introduced by Wlodemierz Tulczyjew, geometric solutions of Hamilton-Jacobi equations, Hamiltonian vector fields and canonical transformations are described by suitable Lagrangian submanifolds belonging to distinct well-defined symplectic structures. This unified point of view has been particularly fruitful in symplectic topology, which is the modern Hamiltonian environment for the calculus of variations, yielding sharp sufficient existence conditions. This line of investigation was initiated by Claude Viterbo in 1992; here, some primary consequences of this theory are exposed in Chapter 8: aspects of Poincaré's last geometric theorem and the Arnol'd conjecture are introduced. In Chapter 7 elements of the global asymptotic treatment of the highly oscillating integrals for the Schrödinger equation are discussed: as is well known, this eventually leads to the theory of Fourier Integral Operators. This short handbook is directed toward graduate students in Mathematics and Physics and to all those who desire a quick introduction to these beautiful subjects.
Veronica Franco (whose life is featured in the motion picture Dangerous Beauty) was a sixteenth-century Venetian beauty, poet, and protofeminist. This collection captures the frank eroticism and impressive eloquence that set her apart from the chaste, silent woman prescribed by Renaissance gender ideology. As an "honored courtesan", Franco made her living by arranging to have sexual relations, for a high fee, with the elite of Venice and the many travelers—merchants, ambassadors, even kings—who passed through the city. Courtesans needed to be beautiful, sophisticated in their dress and manners, and elegant, cultivated conversationalists. Exempt from many of the social and educational restrictions placed on women of the Venetian patrician class, Franco used her position to recast "virtue" as "intellectual integrity," offering wit and refinement in return for patronage and a place in public life. Franco became a writer by allying herself with distinguished men at the center of her city's culture, particularly in the informal meetings of a literary salon at the home of Domenico Venier, the oldest member of a noble family and a former Venetian senator. Through Venier's protection and her own determination, Franco published work in which she defended her fellow courtesans, speaking out against their mistreatment by men and criticizing the subordination of women in general. Venier also provided literary counsel when she responded to insulting attacks written by the male Venetian poet Maffio Venier. Franco's insight into the power conflicts between men and women and her awareness of the threat she posed to her male contemporaries make her life and work pertinent today.
