Sunlight is part of everyday life and we accept it as good-and good it is in a number of ways. The sun is our source of warmth, and of the light by which we see. It is, in fact, the source of the energy with which life continues on earth. It furnishes energy for photosynthesis, and the pro ducts of photosynthesis constitute our food, building materials, and fuel. A steady state of balance and fine interrelationships exists between life on earth and all the forces and stresses in nature. This book will pin point the balance and relationships we share with sunlight. Our primary focus will be on the ultraviolet radiation of the sun, and on the ultraviolet photobiology of life on earth. This is the story of the effects of the sun's ultraviolet radiation, both good and bad, on all of us and all of life. We will explore the nature of the sun's ultraviolet radiation as it reaches the earth's surface today, and as it probably affected the earth in the distant past; and examine the effect of such radiation on all life, unicellular organisms as well as multicellular plants and animals. The effects of the sun's ultraviolet rays are primarily a result of their action upon cells, and secondarily, a result of their interactions between cells. The cell of a multicellular organism-man included-is also part of the tissue of an organ, and the organ is part of the whole organism.

The book, as originally conceived, was to be limited to technical considerations, but the scientific course of event has been so interwoven with non-scientific, but nevertheless related events, the authors felt necessary to include an account of this situation. Accordingly, the book is divided into five sections entitled: Stratospheric ozone Atmospheric processes influencing stratospheric ozone Does man influence stratospheric ozone Effects and research Public policy

This volume contains the formal record of the lectures presented at the 9th Course of the International School of Radiation Damage and Protection held at the "E . Majorana" International Centre for Scientific Culture in Erice (Italy) from May 9 to May 20, 1989. This course was the last of a series of 4 courses, started in 1981, that were dedicated to the assessment of risk hazard from non-ionizing radiation. The proceedings of these courses were all published by Plenum Press with the following headings: 1) M. Grandolfo, S. M. Michaelson and A. Rindi, Eds. : "Biological Effects and Dosimetry of Nonionizing Radiation; Radiofrequency and Microwave Energy", Plenum Press, New York, NATO ASI Series A Life Sciences, Vo1. 49 (1983); 2) M. Grandolfo, S. M. Michaelson and A. Rindi, Eds. : "Biological Effects and Dosimetry of Static and ELF Electromagnetic Fields", Plenum Press, New York, E. Majorana International Science Series, Life Sciences, Vol. 19 (1985) ; 3) M. H. Repacholi, M. Grandolfo and A. Rindi, Eds. : "Ultrasound; medical applications, biological effects and hazard potential", Plenum Press, New York (1987). We hope that all these volumes together may represent a complete textbook and a reference for the students and scientists interested in the physics, biology, measurement and dosimetry, health effects and standard setting, in short, the risk assessment of that wide field of radiation presently classified as non-ionizing radiation. We are indebted to the Associa?ione Italiana Protezione dalle Radiazioni (AIRP), The Internat:l.

Although there are several excellent books covering a few of the specialized areas of photobiology, at the present time there is no book that covers all areas of the science of photobiology. This book attempts to fill this void. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. The first 14 chapters of this book deal with those subspecialty areas, each written by a leader in the field. Chapter 15, entitled "New Topics in Photobiology," highlights areas of research that may be desig nated sUbspecialties of photobiology in the future. This book has been written as a textbook to introduce the science of photobiology to advanced undergraduate and graduate students. The chapters are written to provide a broad overview of each topic. They are designed to contain the amount of information that might be presented in a one-to two-hour general lecture. The references are not meant to be exhaustive, but key refer ences are included to give students an entry into the literature. Frequently a more recent reference that reviews the literature will be cited rather than the first paper by the author making the original discovery. Whenever practical, a classroom demonstration or simple laboratory exercise has been provided to exemplify one or more major points in a chapter.

Make thunder in a can and lightning in a pan, watch the wind at work, learn snow facts and folklore and much, much more! In 10 easy-to-follow chapters, children in grades 1-4 are introduced to the many faces of weather, investigating their environment and making exciting discoveries along the way! Each chapter features indoor and outdoor learning opportunities from experiments and sky watching to discovery centers and extension activities. The hands-on learning tasks are accompanied by lively scientific facts, trivia and lore, and the unique format enables educators to connect weather themes to all areas of the curriculum. Here's a complete approach to learning that opens the doors to discovery and is guaranteed to make children "weather wise."

Dr. Rosenfeld spells out the details on how to prevent, treat, and/or slow down virtually every disorder and complication of aging, including Alzheimer's, cancer, heart disease, impotence, cataracts, osteoarthritis, osteoporosis, stroke, and loss of vision.

Surya Namaskar is a magical name in Indian history and now becoming popular all over the world, it has become a global household name. Surya Namaskar has many references in the Vedas and Puranas. Since that time this yoga has been practiced by many people all over the world. To begin one’s day with the Surya Namaskar is very beneficial as it connects the individual with the cosmos. Out of so many people interested in yoga and spirituality some persons have taken Suryanamaskar as their life style. One such person is Krzysztof Stec from Poland who loves this practice. I remember that as soon as he arrived at Vishwatmak Jangli Maharaj Ashram almost 10 years ago he was talking about and encouraging everyone to start practicing Suryanamaskar. He has been practicing it every day for many years, and in a little more than two hours he performs in excess of 1008 rounds of Suryanamaskar. Such feat is astonishing and worth praising. He has built tremendous stamina and extraordinary endurance over the years with such regular and disciplined practice. The medical practitioners in the nearby town of Kopargaon have examined him and came to conclusion that he has the physiological parameters of 25 year old youngster (as of today he is running 59 years old). Only two years ago he completed a demanding two years’ master degree program at the department of physical education at one of the primary universities of India, at Banaras Hindu University, Varanasi. There he had to compete and work-out with colleagues who were one third his age! Last year when he undertook 42 days’ complete fast for the Gurupurnima (anusthan), he began without water (or any food) and continued for full 23 days and later, to complete the fast, he drank only water. In spite of such severe tapasya (discipline and austerity), when most other people usually stay in bed and barely move or to help themselves get several I.V., he was so energetic and full of vitality that he was swimming daily the distance of 5 to 8 kilometers.

The Danes may have their hygge and the Norwegians their back to the land culture, but the Swedes have 'lagom': an even-keeled approach to a life of balance. Dr Bertil Marklund - a doctor and researcher at the Gothenburg University with over forty years of experience - provides the most cutting-edge research to explain the ten areas we should focus on to better our chances of a long life. This compact guide provides wisdom from the Nordics, a region long known for its healthy and progressive lifestyle. It debunks myths on things we have been told are not good for us but actually can be: did you know drinking coffee will promote your health? Or that more people die of lack of Vitamin D than they do of skin cancer? By providing pragmatic and realistic advice, Dr Marklund gives you the power to make a difference in your own life today and for the future.
