Investigations on the specific effects of blue light on plants began some fifty years ago. In re cent years the growing awareness of blue-light-in duced phenomena in plants, microorganisms, and animals has accelerat ed and expanded this research into an ever-increasing variety of blue light effects in biological systems. In 1977, J .A. Schiff and W .R. Briggs proposed a specific meeting to present and summarize the various blue-light effects and to discuss their mechanisms and possible photoreceptors. In view of the variety of re sponses and the range of organisms affected by blue light the term Blue Light Syndrome seemed to be the only appropriate one for the meeting. With the help of the International Advisory Committee (W.R. Briggs, Stanford; J. Gressel, Rehovot; W. Kowallik, Bielefeld; S. Miyachi, To kyo; W. Rau, Munich, and J.A. Schiff, Waltham), and the very generous financial support provided by the Deutsche Forschungsgemeinschaft as well as by the Bundesministerium fur Forschung und Technologie, the Kultusminister des Landes Hessen, and the Philipps-Universitat Marburg, the "International Conference on the Effect of Blue Light in Plants and Microorganisms" was held in July 1979 in the Philipps-Universitat Mar burg."

Based on extensive interviews with forty women working as prostitutes, Red Light, Blue Light examines a variety of personal developmental experiences and socio-situational factors that can combine to make prostitution neither an inevitable nor inescapable circumstance but a rational occupational choice. This book attempts to analyze why women enter the world of prostitution, how the skills and values of the business are transmitted and how the individuals themselves subjectively define, perceive and rationalise their activity. As opposed to the traditional stereotypical depiction of prostitutes as hopeless, downtrodden victims of male exploitation living lives of poverty, misery and wretchedness, the picture that emerges in this study is of an independent occupational group organizing and controlling the business in which they work. The book also presents a profile of clients of prostitutes and discusses the role of the police. Written in accessible style, the resulting monograph presents a fascinating, unique and comprehensive account of street prostitution in a northern city.

Four years ago The Blue Light Syndrome was published as the Proceed ings of the 1 st International Conference on the Effect of Blue Light in Plants and Microorganisms. Subsequently the interest in this fascinating and growing field of re search has further increased, as is reflected by numerous publications. Blue light effects cover such a wide spectrum of organisms, responses and methods that communication among scientists with backgrounds in biology, biochemistry, and biophysics is particularly necessary. These facts not only justified, but demanded calling the "Blue Light Family" together again. In spite of many fmancial problems, the second confer ence attracted 113 active members from 19 countries. The 2nd International Conference on The Effect of Blue Light in Plants and Microorganisms was held in July 1984, like the first at the University of Marburg. The organizer could again rely on the help of the International Advisory Committee (W. Briggs, Stanford; M. Furuya, Tokyo; J. Gressel, Rehovot; S. Miyachi, Tokyo; W. Rau, Miinchen; J. Schiff, Waltham; P .-S. Song, Lubbock). The very generous financial as sistance from the DFG and the support of the Philipps-Universitat Mar burg and its Sonderforschungsbereich "Zellenergetik and Zelldifferen zierung" were the prerequisites to organizing the conference. The present book consists of 56 original papers. The partitioning into eight chapters is always a problem. The grouping of different aspects of the papers into these chapters has not always been obvious, so that one or the other contribution could possibly fit in another chapter.

The Photobiology of Higher Plants offers a comprehensive, balanced coverage of both photosynthesis (including physiology and global aspects) and photomorphogenesis in plants.

Each chapter includes numerous references to provide a useful starting point for those wishing to learn more about the subject. * Provides combined coverage of both photosynthesis and photomorphogenesis in plants. * Includes an extensice glossary designed to provide easy access to key * Aimed at students in Botany, Plant Science, Agriculture and Forestry * A useful reference for postgraduates and researchers working in the field

Discover the revolutionary power of low-level laser therapy (aka photobiomodulation) for the pain-free treatment of arthritis, psoriasis, hair loss, acne, cold sores, joint pain, scarring, and more. Red light therapy is dramatically changing the world of health care. Studies show using red and near-infrared light can have incredible effects, from managing chronic pain to even slowing the signs of aging. This natural, drug-free, red light therapy treatment can be found at your doctor’s office, spa, and even in the comfort of your own home. These at-home lights are increasing in popularity as they become more affordable and accessible online, but using them safely and effectively is crucial. With so many different devices, online advisories, and treatment options, this book is your go-to guide to understanding the ins and outs of this revolutionary therapy. Inside you’ll find information about: - How light therapy works - Easy-to-understand breakdown of recent studies - Different light source devices and types - The importance of correct dosage - Treatment of chronic pain, skin aging and other conditions, joint pain, and more With patient testimonials and interviews with leading health professionals, Healing with Red Light Therapy will give you all the tools you need to harness the healing power of light therapy.

The second edition of this popular work provides a comprehensive account of all aspects of stomatal biology. The substantially revised text is thoroughly up to date and well illustrated with numerous line illustrations, photographs and comprehensive tables. The theory of gaseous diffusion through stomata is reviewed in a new chapter and sections on signal perception and transduction, guard cell ionic relations and guard cell metabolism have been added. A concluding chapter reviews the genetics and molecular biology of stomata. This work provides a comprehensive reference text which will appeal to advanced students, post-graduates and lecturers in plant physiology.

Stephen Pople, one of today's most respected science authors, has created a totally new physics book to prepare students for examinations. Complete Physics covers all syllabuses due to a unique combination of Core Pages and Further Topics. Each chapter contains core material valid for all syllabuses. Further Topics at the end can be selected to provide the right mix of pages for the syllabus you are teaching. Key Points: · Totally new book constructed from an analysis of all GCSE Physics syllabuses including IGCSE, CXC, and O'Level · Sets the traditional principles of physics in a modern and global perspective and uses illustrations with a worldwide context · Extra topics to give a truly rounded curriculum · Double-page spread format · Ideal for those students intending to take physics to a more advanced level
