Available in PDF, EPUB and Kindle. Book excerpt: Radiation Measurement in Photobiology deals with the measurement of optical radiation and its application in photobiology. Optical radiation detectors as well as the calibration of light sources and detectors are discussed, together with techniques for spectroradiometry and broadband radiometry. Action spectroscopy and ultraviolet radiation dosimetry are also considered. Comprised of nine chapters, this volume begins with an introduction to the basic principles of light measurement, followed by a survey of optical radiation detectors based on physical principles and the problems associated with calibration. The next three chapters deal with important applications and extensions of these radiant measurements, including a short review of biological and medical users of lasers. The final three chapters on specialized studies and developments illustrate the wide diversity that exists in photobiology. These cover ultraviolet radiation dosimetry using polymer films, computer modeling of terrestrial ultraviolet radiation, and the "diffusion optics" in biological media. This book should be of interest to photobiologists.

Available in PDF, EPUB and Kindle. Book excerpt: It is not always the case that the subject of a scientific book and its relevance to everyday li fe are so timely. Photobiology and its si ster subject Radiobiology are now a must for understanding the environment we live in and the impact light, ultraviolet light, and radiation have on all aspects of our life. Photobiology is a true interdisciplinary field. Photobiology research plays a direct role in diverse fields, and a glance at the topics of the symposia covered in this book by over 100 articles shows the breadth and depth of knowledge acquired in fundamental research and its impact on the major issues and applied problems the world is facing. Half a century of photobiology research brought about an understanding of the importance of light to life, both as a necessary source of energy and growth as weIl as its possible dangers. Research in photochemistry and photobiology led to the discoveries of ceIlular repair mechanisms of UV induced damages to DNA and this led to understanding of the effects of hazardous environmental chemieals and mutagenecity , and to the development of genetic engineering. This topic was given due emphasis in several symposia and chapters in this book.
Download or read book Photobiology written by Lars Olof Björn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology. This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.
Download or read book Beyond the Visible written by Pedro J. Aphalo and published by Helsingin yliopisto. This book was released on 2012-11-02 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beyond the Visible: A handbook of best practice in plant UV photobiology presents methods for research on the responses of plants to ultraviolet (UV) radiation. The knowledge needed to make informed decisions about manipulation and quantification of UV radiation is summarized. Practical recommendations for obtaining reliable and relevant data and interpretations are given. The handbook covers research both on terrestrial and aquatic plants and it deals with experimentation on ecological, eco-physiological and physiological questions. The handbook includes 115 figures, mostly in colour, 19 tables and 12 text boxes. It is the result of the activities of COST action FA0906 "UV4growth", and it includes contributions by 17 authors. From the foreword by Dr. Marcel A. K. Jansen: This book ... is an important contribution towards such sound experimental design, promoting both "good practice" in UV-B manipulation, as well as "standardisation" of methodologies. Writing an authoritative book that will steer experimental approaches over the coming years, can not easily be done by an individual, but rather requires the concerted effort of a team of expert scientists. ... This is surely an excellent example of a concerted, Europeanwide activity that will boost the plant UV-B research field in Europe and beyond, for years to come.
Download or read book The Science of Photobiology written by K. C. Smith and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecosystems Evolution and Ultraviolet Radiation written by Charles Cockell and published by Springer Science & Business Media. This book was released on 2001-05-25 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: From microbial to plant ecosystems, this book examines how changes in UV radiation, caused by anthropogenic ozone depletion, as well as changes in radiation levels throughout the evolution of life on Earth, can alter species composition and interspecies competitiveness. It focuses on the evolutionary aspects of the effects of UV as well as the various synergistic interactions of UV radiation with other environmental factors. Because our knowledge of UV effects on whole ecosystems is still at a relatively early stage, an important part of each chapter is an overview of future research directions and indications of where new date and knowledge is needed.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.
Download or read book Photobiological Techniques written by Dennis Paul Valenzeno and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fIrst edition of the Science 0/ Photobiology edited by Kendric C. Smith (plenum Press, 1977) was a comprehensive textbook of photobiology, devoting a chapter to each of the subdisciplines of the fIeld. At the end of many of these chapters there were brief descriptions of simple experiments that students could perform to demonstrate the principles discussed. In the succeeding years some photobiologists felt that a more complete publica tion of experiments in photobiology would be a useful teaching tool. Thus, in the 1980s the American Society for Photobiology (ASP) attempted to produce a laboratory manual in photobiology. Cognizant of these efforts, Kendric Smith elected to publish the second edition of The Science o/Photobiology (1989) without experiments; anticipating the comple tion of the ASP laboratory manual. Unfortunately, the initial ASP efforts met with limited success, and several years were to pass before a photobiology laboratory manual became a reality. One of the major stumbling blocks to production of an accurate and reliable laboratory manual was the requirement that the experiments be tested, not just by the author who is familiar with the techniques, but by students who may be quite new to photobiology. How could this be accomplished with limited resources? Many ideas were considered and discarded, before a workable solution was found. The catalyst that enabled the careful screening of all experiments in this book was a NATO Advanced Study Institute (ASI) devoted entirely to this purpose.
Download or read book UV B Radiation written by Vijay Pratap Singh and published by John Wiley & Sons. This book was released on 2017-02-02 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet-B (UV-B) is electromagnetic radiation coming from the sun, with a medium wavelength which is mostly absorbed by the ozone layer. The biological effects of UV-B are greater than simple heating effects, and many practical applications of UV-B radiation derive from its interactions with organic molecules. It is considered particularly harmful to the environment and living things, but what have scientific studies actually shown? UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth presents a comprehensive overview of the origins, current state, and future horizons of scientific research on ultraviolet-B radiation and its perception in plants. Chapters explore all facets of UV-B research, including the basics of how UV-B's shorter wavelength radiation from the sun reaches the Earth's surface, along with its impact on the environment's biotic components and on human biological systems. Chapters also address the dramatic shift in UV-B research in recent years, reflecting emerging technologies, showing how historic research which focused exclusively on the harmful environmental effects of UV-B radiation has now given way to studies on potential benefits to humans. Topics include: UV-B and its climatology UV-B and terrestrial ecosystems Plant responses to UV-B stress UB- B avoidance mechanisms UV-B and production of secondary metabolites Discovery of UVR8 Timely and important, UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth is an invaluable resource for environmentalists, researchers and students who are into the state-of-the-art research being done on exposure to UV-B radiation.
