Ecological Consequences of Artificial Night Lighting by Catherine Rich,Travis Longcore Pdf

While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.

The Effects of Constant Light on Visual Processes by Theodore P. Williams Pdf

" ... And the evening and the morning were the third day ... And God made two great lights; the greater light to rule the day and the lesser light to rule the night ... And the evening and the morning were the fourth day." The First Book of Moses, called Genesis (1: 13,16,19). There was daytime and nighttime before there was a sun or a moon. An interesting thought: How long were each of those first three days? Without a sun to reckon its length, a day could have been longer or shorter than 24 hours. Animals, says Genesis, appeared on the fifth day and by that time the sun and moon were illuminating the earth, presumably in cyclic fashion and with a period of 24 hours. A good thing, too, as readers of this monograph will as certain. The papers collected into this volume are written versions of 45 minute talks given at a symposium on "The Effects of Constant Light on Visual Processes", held at The Florida State University in Tallahassee on April 25-27, 1979. The conference was supported by the Psychobiology Program and handled, logistically, by the Center for Professional Development and Public Services. It was recognized that limitations on time and funds made prohibitive the invitation of others who may be doing interesting and related work. But, our earnest hope is that what is compiled here is a good blend of "true" light-damage and "relevant related" work.

Essayism by Brian Dillon Pdf

A compelling ode to the essay form and the great essaysists themselves, from Montaigne to Woolf to Sontag. Essayism is a book about essays and essayists, a study of melancholy and depression, a love letter to belle-lettrists, and an account of the indispensable lifelines of reading and writing. Brian Dillon’s style incorporates diverse features of the essay. By turns agglomerative, associative, digressive, curious, passionate, and dispassionate, his is a branching book of possibilities, seeking consolation and direction from Michel de Montaigne, Virginia Woolf, Roland Barthes, Theodor Adorno, Walter Benjamin, Georges Perec, Elizabeth Hardwick, and Susan Sontag, to name just a few of his influences. Whether he is writing on origins, aphorisms, coherence, vulnerability, anxiety, or a number of other subjects, his command of language, his erudition, and his own personal history serve not so much to illuminate or magnify the subject as to discover it anew through a kaleidoscopic alignment of attention, thought, and feeling, a dazzling and momentary suspension of disparate elements, again and again.

Visual and Non-Visual Effects of Light by Agnieszka Wolska,Dariusz Sawicki,Małgorzata Tafil-Klawe Pdf

The introduction of artificial lighting extends the time of wakefulness after dark and enables work at night, thus disturbing the human circadian rhythm. The understanding of the physiological mechanisms of visual and non-visual systems may be important for the development and use of proper light infrastructure and light interventions for different workplace settings, especially for shift work conditions. Visual and Non-Visual Effects of Light: Working Environment and Well-Being presents the impact of lighting in the working environment on human health, well-being and visual performance. The physiological explanation of the visual and non-visual effects of light on humans which discusses the biological bases of image and non-image forming vision at the cellular level may be of particular interest to any professional in the field of medicine, physiology, and biology. It is one of the intentions of this book to put forward some recommendations and examples of lighting design which take into account both the visual and non-visual effects of light on humans. These may be of particular interest to any professional in the field of lighting, occupational safety and health, and interior design. "What effects on health can a light ‘overdose’ or light deficiency have? What is bad light? The authors of the monograph provide answers to these questions. Just as for a physicist, the dual nature of light comprises an electromagnetic wave and a photon, the duality of light for a physician comprises visual and non-visual effects." --------------------------------------------------------Prof Jacek Przybylski, Medical University of Warsaw "This is a unique publication in the field of lighting technology. The authors have skillfully combined both the technical and biomedical aspects involved, which is unprecedented in the literature available. As a result, an important study has been created for many professional groups, with a significant impact on the assessment of risks associated with LED sources." --------------------------------------------Prof Andrzej Zając, Military University of Technology, Warsaw

Light Science by Thomas D. Rossing,Christopher J. Chiaverina Pdf

Intended for students in the visual arts and for others with an interest in art, but with no prior knowledge of physics, this book presents the science behind what and how we see. The approach emphasises phenomena rather than mathematical theories and the joy of discovery rather than the drudgery of derivations. The text includes numerous problems, and suggestions for simple experiments, and also considers such questions as why the sky is blue, how mirrors and prisms affect the colour of light, how compact disks work, and what visual illusions can tell us about the nature of perception. It goes on to discuss such topics as the optics of the eye and camera, the different sources of light, photography and holography, colour in printing and painting, as well as computer imaging and processing.

Effects of Light on Materials in Collections by Terry T. Schaeffer Pdf

The impact of light on works of art and archival materials has long been an issue of concern to conservators and other museum professionals, yet the literature on this subject has never been systematically reviewed. This volume fills that gap by providing a survey of the impact of exposure to light with an emphasis on photoflash and reprographic sources. The information provided will assist the professional audience, especially conservators and collections managers, in assessing the risk to art and archival objects of such exposures. The text surveys relevant photophysical and photochemical principles, photometric and radiometric measurement, and the spectral outputs of several light sources. Materials discussed include colorants and natural fibers; pulp, paper, and wood; natural and synthetic polymers; fluorescent whitening agents; photographic and reprographic materials; and objects containing combinations of materials. Approximations and assumptions used in the evaluation process are discussed in some detail, with examples of the different types of calculations. The Research in Conservation reference series presents the findings of research conducted by the Getty Conservation Institute and its individual and institutional research partners, as well as state-of-the-art reviews of conservation literature. Each volume covers a topic of current interest to conservators and conservation scientists.

Blue Light Effects in Biological Systems by H. Senger Pdf

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.
