Mass Contacts is an astounding story that says that Contact has begun from one who knows. A detailed report of contacts with human type aliens on the Adriatic coast, which answers many of our questions, this book is a milestone for ufologists wh study Contact. They were here and many look like us! It's time for disclosure. Paola Leopizzi Harris-Researcher and Author: Connecting the Dots; Making Sense of UFO Phenomena; Exopolitics: How Does One Speak to a Ball of Light? This book is a true milestone in the spreading of the reality of contacts between our humanity and extraterrestrials, both in the past and now; it gives rise to vital importants, hints in order to understand the epoch-making events that are waiting for us, and inteat with them in the best way. Tom Bosco-NEXUS Magazine-Edizione Italiana Eng. Stefani Breccia and I are friends, and have been responsible keepers of truths that not always were sharable with other people. Both of us have dedicated a significant part of our lives to UFO's, myself trying to spread this reality in the best way. Stefano trying to understand its roots, both being aware of how important the phenomenon is. And so I have acted as a midwife to the important result of Stefano's work, being convinced that reading this book is at the same time necessary and useful. Roberto Pinotti-Director, Centro Ufologico Nationale (CUN), Italy This book, based upon memories of experiences covering a period of many years, is charming above all for it concerns the contact, first, and then the coexistence of humans and aliens, working toward a single goal.

As mechanical systems become more complex so do the mathematical models and simulations used to describe the interactions of their parts. One area of multibody theory that has received a great deal of attention in recent years is the dynamics of multiple contact situations occurring in continuous joints and couplings. Despite the rapid gains in our understanding of what occurs when continuous joints and couplings interact, until now there were no books devoted exclusively to this intriguing phenomenon. Focusing on the concerns of practicing engineers, Multibody Dynamics with Unilateral Contacts presents all theoretical and applied aspects of this subject relevant to a practical understanding of multiple unilateral contact situations in multibody mechanical systems. In Part 1, Professor Pfeiffer and Dr. Glocker provide an exhaustive review of the laws and principles governing the dynamics of unilateral contacts in multibody mechanical and technical systems. Among the topics covered are multibody and contact kinematics, the dynamics of rigid body systems, multiple contact configurations, detachment and stick-slip transitions, frictionless impacts, impacts with friction, and the Corner law of contact dynamics. In Part 2, the authors present numerous applications of the theories presented in Part 1. Each chapter in this part is devoted to a different law, theory, or model, such as discontinuous force laws, classical impact theory, Coulomb's friction law, and mechanical and mathematical models of impacts and friction. In addition, each chapter features several practical examples that allow engineers to observe the concepts described in action. Examples are drawn from a broad array of fields and range from hammering in gears as occurring in a synchronous generator to impacts and friction as observed in a child's woodpecker toy, from a demonstration of classical impact theory using an automobile gear box example, to Coulomb's friction law as applied to a turbine blade damper. Multibody Dynamics with Unilateral Contacts is an indispensable resource for mechanical engineers working on all types of multibody systems and the friction and vibration problems that can occur in them. It is also a valuable reference for researchers studying nonlinear dynamics. The only book devoted entirely to the theory and applications of onE of the most crucial aspects of multibody system design. This is the first book to focus exclusively on the theory and applications of multiple contact situations occurring in continuous joints and couplings in multibody systems. As such, it is a valuable resource for engineers working on mechanical systems with interrelated multiple parts. Multibody Dynamics with Unilateral Contacts * Provides a comprehensive examination of the laws and principles governing the dynamics of unilateral contacts in multibody mechanical and technical systems. * Presents the latest mathematical models and simulation techniques for describing the interactions of joints and couplings in multibody systems. * Describes practical applications for all the concepts covered. * Includes numerous examples drawn from a wide range of fascinating and enlightening real-world demonstrations, including everything from an airplane's landing gear to a child's toy.

Seventeen distinguished historians and political scientists discuss the phenomenon of Indian Nationalism, one hundred years after the founding of the Congress party. They offer important new interpretations of Nationalism's evolution during more than six decades of crucial change and rapid growth. As India's foremost political institution, the National Congress with its changing fortunes mirrored Indian aspirations, ideals, dreams, and failures during the country's struggle for nationhood. Many difficulties face by the pre-independence Indian National Congress are critically examined for the first time in this volume. Major times of crisis and transition are considered, as well as the tension between mass action and political control and the problem of creating and maintaining unity in the face of divisive social and economic interests and between deeply hostile religious communities. A composite portrait of the Congress Party emerges. We see a coalition of often conflicting communities and interests much like India itself, struggling to stay together, tenuously united by little more at times than a common "enemy," the imperial British Raj. But linked together in precarious, seemingly haphazard fashion, shifting networks of elite political entrepreneurs manage to keep India's National Congress alive long enough to convince the British that it would be easier to "Quit India" than to try to hang on to it by force. With the abrupt transfer of power form the British to the independent Dominions of India and Pakistan in 1947, Congress provided institutional sinews for the administration of what had been British India and over five hundred Princely States. By contributing to a deeper understanding of India's nationalist experience, this volume may illuminate the experience of other Third World states. Essays by:S. BhattacharyaJudith M.

Since the 1970s symposia or colloquia devoted to recent research on close binaries have been held around the world almost annually. At meetings of the General Assembly of the International Astronomical Union this topic has also been discussed in detail at presentations in various commission meetings and also as invited talks by leading astronomers in the field. In recent years, fundamental changes have taken place in the study of close binaries due to the improvements in observational techniques, extension of observations from X-ray to radio regions of the electromagnetic spectrum, and advances in theoretical studies. For more than a decade, a group of astronomers at Ege University Observatory has been concentrating on active close binaries with particular emphasis on the behaviour of the light curves of chromospherically active systems. Thus, we decided to organize an international meeting in Western Anatolia, where this part of Turkey had been the cradle for great developments in science during antiquity. KUljadasi, located only minutes away from Ephesus, one of the seven wonders of the world, was selected to be the meeting site. Close binary systems constitute a very rich source of information about the physical properties of the component stars. Some systems are eclipsing variables, where periodic recurrences of eclipses are observed as comparatively brief decreases in the total brightness of the binary system. Precise methods of photometric observations make it possible to obtain the light variations of these systems because of eclipses and other phenomena.

The history of musical instruments is nearly as old as the history of civilization itself, and the aesthetic principles upon which judgments of musical quality are based are intimately connected with the whole culture within which the instruments have evolved. An educated modem Western player or listener can make critical judgments about particular instruments or particular per formances but, to be valid, those judgments must be made within the appro priate cultural context. The compass of our book is much less sweeping than the first paragraph might imply, and indeed our discussion is primarily confined to Western musical instruments in current use, but even here we must take account of centuries of tradition. A musical instrument is designed and built for the playing of music of a particular type and, conversely, music is written to be performed on particular instruments. There is no such thing as an "ideal" instrument, even in concept, and indeed the unbounded possibilities of modem digital sound-synthesis really require the composer or performer to define a whole set of instruments if the result is to have any musical coherence. Thus, for example, the sound and response of a violin are judged against a mental image of a perfect violin built up from experience of violins playing music written for them over the centuries. A new instrument may be richer in sound quality and superior in responsiveness, but if it does not fit that image then it is not a better violin.
