Book excerpt: The Human Eye and the Sun, ""Hot"" and ""Cold"" Light is a translation from the Russian language and is a reproduction of texts from Volume IV of S.I. Vavilov, president of the U.S.S.R. Academy of Sciences. The book deals with theoretical and practical developments in lighting techniques. The text gives a brief introduction on the relationship of the human eye and the sun, describing the properties of light, of the sun, and of the human eye. The book describes hot (incandescence) and cold light (luminescence) as coming from different sources. These two types of light are compared. The text also discusses the chemical production of light such as that produced when hydrogen peroxide and potassium ferricyanide are added to a solution of triaminophthalic hydrazide with alkali. A blue light will emanate, lasting for hours or days, and more importantly, the temperature of the vessel containing the mixture is relatively low. The book also evaluates the efficiency of the electric bulb in terms of conversion from the source — power producing coal — to line distribution, and actual luminescence. The book expounds on the benefits of a lighting method in the form of fluorescence. It also explains the properties of fluorescence. The book is of interest to students of physics, electronics, and electrical engineering. It can also be appreciated by the general reader with some interest in history and scientific discoveries.

Download or read book Life Under the Sun written by Peter A. Ensminger and published by Yale University Press. This book was released on 2008-10-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Which fungus is as sensitive to light as the human eye? What are the myths and facts about the ozone hole, tanning, skin cancer, and sunscreens? What is the effect of light on butterfly copulation? This entertaining collection of essays explores how various organisms -- including archaebacteria, slime molds, fungi, plants, insects, and humans -- sense and respond to sunlight. The essays in Peter A. Ensminger's book cover vision, photosynthesis, and phototropism, as well as such unusual topics as the reason why light causes beer to develop a "skunky" odor. He introducec us to the kinds of eyes that have evolved in different animals, including those in a species of shrimp that is ostensibly eyeless; gives us a better appreciation of color vision; explains how plowing fields at night may be used to control weeds; and tells about variegate porphyria, a metabolic disease that makes people very sensitive to sunlight and may have afflicted King George III of England. These engaging essays present a complicated yet fascinating subject in an accessible way. The book will be treasured by anyone interested in the wonders of biology.

Download or read book Polarized Light and Polarization Vision in Animal Sciences written by Gábor Horváth and published by Springer. This book was released on 2014-10-30 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell’s window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. This Part also examines polarized “light pollution” induced by anthropogenic factors such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.

Download or read book Handbook of Advanced Lighting Technology written by Robert Karlicek and published by Springer. This book was released on 2016-05-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Advanced Lighting Technology is a major reference work on the subject of light source science and technology, with particular focus on solid-state light sources – LEDs and OLEDs – and the development of 'smart' or 'intelligent' lighting systems; and the integration of advanced light sources, sensors, and adaptive control architectures to provide tailored illumination which is 'fit to purpose.' The concept of smart lighting goes hand-in-hand with the development of solid-state light sources, which offer levels of control not previously available with conventional lighting systems. This has impact not only at the scale of the individual user, but also at an environmental and wider economic level. These advances have enabled and motivated significant research activity on the human factors of lighting, particularly related to the impact of lighting on healthcare and education, and the Handbook provides detailed reviews of work in these areas. The potential applications for smart lighting span the entire spectrum of technology, from domestic and commercial lighting, to breakthroughs in biotechnology, transportation, and light-based wireless communication. Whilst most current research globally is in the field of solid-state lighting, there is renewed interest in the development of conventional and non-conventional light sources for specific applications. This Handbook comprehensively reviews the basic physical principles and device technologies behind all light source types and includes discussion of the state-of-the-art. The book essentially breaks down into five major sections: Section 1: The physics, materials, and device technology of established, conventional, and emerging light sources, Section 2: The science and technology of solid-state (LED and OLED) light sources, Section 3: Driving, sensing and control, and the integration of these different technologies under the concept of smart lighting, Section 4: Human factors and applications, Section 5: Environmental and economic factors and implications

Download or read book The Overfat Pandemic written by and published by Simon and Schuster. This book was released on 2017-09-12 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research demonstrates that up to 76 percent of the world’s population—or 5.5 billion people—are overfat, defined as having sufficient excess body fat to impair health. This includes nearly 90 percent of Americans—one of the highest percentages worldwide. In The Overfat Pandemic, Dr. Philip Maffetone reveals common misconceptions regarding the real meaning of “overfat,” factors that helped cause this global pandemic, and ways individuals can remedy the situation with the proper food and exercise. Other major points in the book include: • The distinction between “overweight” and “overfat” • How normal-weight people can be overfat • Why those who exercise can still be overfat, including athletes • Why waist measurement is better than the bathroom scale • How individuals can take charge of their body fat • How the overfat pandemic can be remedied through simple lifestyle changes and without diets As little as 14 percent of the world’s population has a normal body-fat percentage, and that number may be shrinking. This book aims to curtail the overfat epidemic by exposing a decades-long problem and offering a research-based, practical solution to help prevent and treat it.

Download or read book Spaceflight Associated Neuro Ocular Syndrome written by Andrew G. Lee and published by Academic Press. This book was released on 2022-07-16 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration's (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions. - Written in an easy-to-read manner, the book adopts a translational approach and explores the science and the clinical manifestations of Space flight associated neuro-ocular syndrome. It is also multi-disciplinary and suitable for both clinicians and researchers in ophthalmology, neurology, and aerospace medicine interested in SANS - SANS is a unique space flight disorder that has no terrestrial equivalent. The book involves contributions from international experts across multiple disciplines to tackle the problem of SANS - Summarizes and reviews the current findings of SANS, including possible mechanisms and potential etiologies, clinical manifestations, current reports on the in-flight and terrestrial human and animal research, and ocular imaging findings

Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES EDITORS’ CHOICE • A novelist discovers the dark side of Hollywood and reckons with ambition, corruption, and environmental collapse in “a darkly satirical reflection of ecological reality” (Time) LONGLISTED FOR THE JOYCE CAROL OATES PRIZE • ONE OF THE BEST BOOKS OF THE YEAR: The New York Times Book Review, Time, Los Angeles Times, The Philadelphia Inquirer, Vulture, Thrillist, Literary Hub “An urgent novel about our very near future, and a deeply addictive pleasure.”—Katie Kitamura, author of Intimacies Novelist Patrick Hamlin has come to Los Angeles to oversee the film adaptation of one of his books and try to impress his wife and daughter back home with this last-ditch attempt at professional success. But California is not as he imagined. Drought, wildfire, and corporate corruption are everywhere, and the company behind a mysterious new brand of synthetic water seems to be at the root of it all. Patrick finds an unlikely partner in Cassidy Carter—the cynical starlet of his film—and the two investigate the sun-scorched city, where they discover the darker side of all that glitters in Hollywood. Something New Under the Sun is an unmissable novel for our present moment—a bold exploration of environmental catastrophe in the age of alternative facts, and “a ghost story not of the past but of the near future” (The New York Times).

Download or read book Staring at the Sun written by Irvin D. Yalom and published by Scribe Publications. This book was released on 2008-03-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written in Irvin Yalom’s inimitable story-telling style, Staring at the Sun is a profoundly encouraging approach to the universal issue of mortality. In this magisterial opus, capping a lifetime of work and personal experience, Dr Yalom helps us recognise that the fear of death is at the heart of much of our day-to-day anxiety. This reality is often brought to the surface by an 'awakening experience' — a dream, a loss (such as the death of a loved one, a divorce, or the loss of a job or home), illness, trauma, or ageing. Once we confront our own mortality, Dr Yalom writes, we are inspired to rearrange our priorities, communicate more deeply with those we love, appreciate more keenly the beauty of life, and increase our willingness to take the risks necessary for personal fulfillment. This is a book with tremendous utility, including the provision of techniques for dealing with the most prevalent kinds of fears of death — especially by living in the here and now, and by embracing what Dr Yalom calls ‘rippling’, the influence and impact we all have that has a life beyond our own.
