This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.
This is the first volume of new book series on biophysics and biocybernetics, initiated by the Istituto Italiano per gli Studi Filosofici.A main problem in biophysics is the interaction of light information with functional living structures, in order to shape the organism's behaviour. Although the processes of photoreception and phototransduction are articulated in various ways in different living beings — as it is seen in the subdivision of the topics in this volume on microorganisms, invertebrates, and vertebrates — general ways of light signal reception and transduction through light energy, i.e., photosensitive molecule interactions, could be observed. Highly sophisticated advanced techniques are employed in this research field.
The first edition of The Science of Photobiology was published in 1977, and was the first textbook to cover all of the major areas of photobiology. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. In this edition, however, the topics of phototechnology and spectroscopy have been com bined in a new chapter entitled "Photophysics." The other subspecialty areas remain the same, i.e., Photochemistry, Photosensitization, UV Radiation Effects, Environmental Photobiology, Photomedicine, Circadian Rhythms, Extraretinal Photoreception, Vision, Photomorphogenesis, Photomovement, Photosynthesis, and Bioluminescence. This book has been...
The book describes the significant multidisciplinary research findings at the Università Politecnica delle Marche and the expected future advances. It addresses some of the most dramatic challenges posed by today’s fast-growing, global society and the changes it has caused. It also discusses solutions to improve the wellbeing of human beings. The book covers the main research achievements in the different disciplines of the physical sciences and engineering, as well as several research lines developed at the university’s Faculty of Engineering in the fields of electronic and information engineering, telecommunications, biomedical engineering, mechanical engineering, manufacturing technologies, energy, advanced materials, chemistry, physics of matter, mathematical sciences, geotechnical engineering, circular economy, urban planning, construction engineering, infrastructures and environment protection, technologies and digitization of the built environment and cultural heritage. It highlights the international relevance and multidisciplinarity of research at the university as well as the planned research lines for the next years.
The Biology of Euglena, Volume III: Physiology covers areas of investigation on Euglena, focusing in particular on its physiology. The book demonstrates the wide utilization and research on the members of the genus, especially Euglena gracilis. The book discusses, in particular, the essential features of organelle distribution and structure in Euglena, and euglenoid surfaces. It presents circadian rhythms reported for Euglena, as well as the organism's movement and locomotion. It also explains the various aspects of sensory responses of Euglena gracilis to photic, chemical, and mechanical stimuli. In addition, the book addresses the stimulation and inhibition of the metabolism and growth of Euglena gracilis. Lastly, the Euglena chloroplast membrane, including its structure, function, and photocontrol of its development are described.
The main purpose of this book is to unify approaches and ideas in the field of aneural sensory transduction. This field has recently come to the attention of several research groups in various disciplines, and their number seems to be growing. Unfortunately, because of the diverse scientific backgrounds of the researchers in the field, the apparent heterogeneity of experimental techniques (i. e. , behavioral response analysis, sophisticated biochemical and genetic manipulations, conventional and pulsed laser spectroscopy) and theoretical approaches may be discouraging, for both the experienced worker and the new comer. Actually, this heterogeneity is more apparent than real, and unifying con...
This volume or1g1nates from a NATO Advanced Study Institute on "Photoreceptors" dedicated to M.G.F. Fuortes, held in Erice 1-12 July 1981. The lectures given at the course provided a general review of the photoreceptors functions in both vertebrate and inver tebrate eyes. Elaborating on the most recent hypotheses the lec tures also added new and interesting details. In order to preserve the novelty and freshness of the subject matter and thus ensure the usefulness of the volume, the authors in their written contributions emphasize more specific findings of their current research rather than the tutorial nature of the lectures actually presented. The contributors of this volume wish to dedicate their papers to the memory of Mike Fuortes, who has been for many of them an inspiring collegue and friend. Five papers that do not strictly pertain to the topics of the course are also included in the volume, the authors could not attend the meeting, but wanted to contribute an article to this memorial volume.
This volume contains the lectures given at the NATO Advanced Study Institute on "Biophysics of Photoreceptors and Photomovements in Microorganisms" held in Tir renia (Pisa), Italy, in September 1990. The Institute was sponsored and mainly funded by the Scientific Affairs Division of NATO; the Physical Science Committee and the Institute of Biophysics of National Research Council of Italy also supported the School and substantially contributed to its success. It is our pleasant duty to thank these institu tions. Scientists from very different backgrounds contributed to the understanding of this fast developing field of research, which has seen considerable progress during the last years. The ...
This first complete resource on photosensory receptors from bacteria, plants and animals compiles the data on all known classes of photoreceptors, creating a must-have reference for students and researchers for many years to come. Among the editors are the current and a former president of the American Society for Photobiology.
