The dynamics of mechanical rigid-body mechanisms is a highly developed discipline. The model equations that apply to the tremendous variety of ap- plications of rigid-body systems in industrial practice are based on just a few basic laws of, for example, Newton, Euler, or Lagrange. These basic laws can be written in an extremely compact, symmetrical, and esthetic form, simple enough to be easily learned and kept in mind by students and engi- neers, not only from the area of mechanics but also from other disciplines such as physics, or mathematics, or even control, hydraulics, or electronics....

When discussing the drug, the bug, and the host in the past, emphasis was laid mainly upon the interaction between antibiotics and bacteria or the reaction of the host to the invading organism. Today, however, standardized immunologic parameters are available for evaluating cellular and humoral responses and an increasing number of publications deal with the host reaction to the antibiotics administered. Some re searchers and clinicians felt that the time had come to bring together investigators studying the influence of antibiotics on the host-parasite relationship. The first section of this...

Integrating the history of Paris with the history of consumption, the press, publicity, advertising and spectacle, this book traces the evolution of the urban core districts of consumption and explores elements of consumer culture such as the print media, publishing, retail techniques, tourism, city marketing, fashion, illustrated posters and Montmartre culture in the nineteenth century. Hahn emphasizes the tension between art and industry and between culture and commerce, a dynamic that significantly marked urban commercial modernity that spread new imaginary about consumption. She argues...
