Tens of thousands of miles above Earth's atmosphere, orbiting this planet like pieces from a child's giant erector set, NASA's massive International Space Station slowly takes shape. When completed, as many as 16 countries will provide crew members for this orbiting international community. But while this will not be the first extended stay of humans in space-Skylab, Mir Space Station, and Shuttle-Mir missions all involved extended-stay periods-it will give birth to some new questions about one of space exploration's biggest concerns: providing adequate nutrition essential to good physical and mental health in space. Nutrition in Spaceflight and Weightlessness Models consolidates nutritional observations from 38 years of human spaceflight. It is a compilation of nutritional knowledge and accomplishments from the early 1970's to the recent Shuttle-MIR program. It provides basic nutritional concepts, as well as broad coverage, of the effect of space and weightlessness on nutrition status and physiology. Nutrition in Spaceflight and Weightlessness Models addresses the utility of ground-based weightlessness simulations; the role of electrolytes, calcium, protein, iron, and micronutrients in optimal nutrition; and energy utilization by space crews. The book also explores regenerative life-support and food systems for space and planetary missions; the results of basic research in metabolism that illustrate the physiological changes that occur during spaceflight; new concepts and recommendations for astronaut nutrition in future spaceflights; and, the lab capabilities of the International Space Station.
This book focuses on all of the major problems associated with the absence of body weight in space, by analyzing effects, adaption, and re-adaptation upon returning to Earth, using sound scientific principles embedded in a historical context. Serious problems for space travelers range from Space Motion Sickness (SMS) to recently discovered ocular effects that may permanently impair vision. Fluid loss and shifts, spinal changes, and bone and muscle loss are also all results of weightlessness. Starting with a brief definition and history of weightlessness, the authors then address in detail each problem as well as the countermeasures aimed at alleviating them. In some cases, alternative hypotheses regarding what can and should be attempted are also presented. As plans for long-term missions to the Moon and Mars develop, it will be essential to find countermeasures to weightlessness that are effective for missions that could span years.

"As a child, author Ray Rizzo suffered a head injury that left him with severe headaches and occasional visionary states. At seventeen, he began to study yoga and to practice fasting, meditation, and shamanism, which alleviated his chronic symptoms. In his own recovery, he discovered an ability to assist others in their healing processes-a quest that would culminate in a traditional shamanic apprenticeship deep in the Amazon jungle. There, after nearly a month of isolation and using more than ten years of experience in the healing arts, he developed his unique synthesis. " The style is no style. The goal is to practice what is most efficient and effective. "Weightlessness" includes guidance on a number of techniques and topics, including the Sun Salute; the Swimming Dragon; hatha yoga; essential Pilates; secret chi kung forms; therapeutic exercises; optimal nutrition; breathing; metaphysics. Whether you are an athlete, yoga practitioner, dancer, or martial artist-or even if you are new to movement-this guide can help you, in as little as fifteen minutes a day, to transform your body-mind, deepen your practice, increase energy, overcome injuries, and discover the feeling of "Weightlessness."
This work discusses the problem of physical meaning of the three main dynamical properties of matter motion, namely gravitation, inertia and weightlessness. It considers that Newtonian gravitation and Galileo’s inertia are the centrifugal effects of interaction energy of a self-gravitating n-body system and its potential field. A self-gravitating celestial body appears to be an excellent natural centrifuge that is rotated by the energy of interacting elementary particles. Weightlessness is a consequence of the centrifugal effect of elementary particles interaction that appears at differentiation of a body matter with respect to density. The author analyzes the problem of creation of mass particles and elements from the elementary particles of “dark matter”, and discusses the basic physics of the Jacobi dynamics from the viewpoint of quantum gravitation. Chapters assert that the fundamentals of Jacobi dynamics completely correspond to conditions of natural centrifuges. The centrifuge is an excellent experimental model for the study of dynamical effects in solving the many body problem. In this book, readers may follow the demonstration of some of those studies and follow derivations, solutions and conclusions that provide a solid basis for further research in celestial mechanics, geophysics, astrophysics, geo- and planetary sciences.

This volume includes edited versions of papers presented to the Third International Conference of the European Science Education Research Association, held in Thessaloniki, Greece, in August 2001. The aim of the Conference was to present various perspectives of research in science education in the context of the rapidly developing knowledge-based society. It offers a global presentation of issues under study for improving science education research in the context of the knowledge-based society at a European and international level. The first chapters handle several theoretical approaches, research overviews and research methodologies as well as the popular topic of teaching and learning of science. The following chapters are devoted to studies related to the development, use and integration of I.C.T. in science education, as well as to science teachers' knowledge and aspirations and to the linking of research to teaching practices. The volume closes with a review of completed or current international research projects which are being undertaken by groups from different countries.

The implications of weightlessness as encountered in space flight are discussed, and the known research dealing with the psychological and physiological effects of zero gravity is critically reviewed. Topics are grouped under the headings of orientation, psychomotor performance, and physiological functions, with a special section on methods of research. The major problem area indicated is the effect of weightlessness on gravity oriented sensory mechanisms, particularly the vestibular apparatus, and consequently on both physiological functions and psychomotor performance. An extensive bibliography is included.
If someone told you the path to unburdening your body and mind requires more weight, would you listen? In Pursuit of Weightlessness is a journey through the trenches of mind-body fitness. Tom Fazio explores principles of peace, power, and enlightenment under the iron fists of Shaolin monks, high on hallucinogenic mushrooms, amid unexpected homelessness, and through random dice-dictated experiments. Along the way you'll discover the most effective techniques to burn fat, build muscle, bulletproof the body, overcome personal challenges, and liberate your mind from all that holds you back. This is not a mere physical training manual or a simple guide to meditation and 'inner peace.' This is a gritty, pragmatic prescription for living with passion. The reader will learn exactly what's required to transform the body, unburden the mind, and become weightless.

Since our first manned space flights we have learned much about how the human body adapts to the space environment and in particular, to the absence of gravity. Today, space research provides a better understanding of our physiological response mechanisms to microgravity. Space and Life: An Introduction to Space Biology and Medicine describe
