Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effects of Light on Plants: A Literature Review, 1950 Extreme variability is one outstanding characteristic of daylight. The voluminous observational data available show that many variables are involved. At noon, on a clear day, at sea level, the skylight accounts for as much as 15 percent or more of the total solar radiation received on a horizontal surface. 'just after sunrise and just before sunset its energy value, although low on an absolute basis, actually exceeds that of direct sunlight. Skylight is richer in shorter light rays than direct sunlight. However, in dealing with effects of sunlight on plant growth consideration usually is given only to the combined energy values of the diffused and the direct-light fractions.

Download or read book Light and Plants written by Robert Jack Downs and published by Forgotten Books. This book was released on 2017-10-28 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Light and Plants: A Series of Experiments Demonstrating Light Effects on Seed Germination, Plant Growth, and Plant Development; January 1961 Vegetative growth of plants is to a large degree controlled by light. Plants grown in total darkness have very long internodes, small leaves, and are yellow in color because no chlorophyll is formed. If the dark grown plants are exposed to weak light for a minute or two each day, the plants have shorter internodes and normal-size leaves, although they may still be yellow and without visible chlorophyll. Daily exposures of the plants to light of higher intensities or for a longer duration may not change the size of the leaves or inter nodes of the plants from that obtained with brief exposures to light of low intensity, but the plants turn green as chlorophyll is formed.

Download or read book Effects of Light on Materials in Collections written by Terry T. Schaeffer and published by Getty Publications. This book was released on 2001-08-16 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Optical science and engineering affect almost every aspect of our lives. Millions of miles of optical fiber carry voice and data signals around the world. Lasers are used in surgery of the retina, kidneys, and heart. New high-efficiency light sources promise dramatic reductions in electricity consumption. Night-vision equipment and satellite surveillance are changing how wars are fought. Industry uses optical methods in everything from the production of computer chips to the construction of tunnels. Harnessing Light surveys this multitude of applications, as well as the status of the optics industry and of research and education in optics, and identifies actions that could enhance the field's contributions to society and facilitate its continued technical development.
Download or read book The Age of Edison written by Ernest Freeberg and published by Penguin. This book was released on 2014-01-28 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sweeping history of the electric light revolution and the birth of modern America The late nineteenth century was a period of explosive technological creativity, but more than any other invention, Thomas Edison’s incandescent light bulb marked the arrival of modernity, transforming its inventor into a mythic figure and avatar of an era. In The Age of Edison, award-winning author and historian Ernest Freeberg weaves a narrative that reaches from Coney Island and Broadway to the tiniest towns of rural America, tracing the progress of electric light through the reactions of everyone who saw it and capturing the wonder Edison’s invention inspired. It is a quintessentially American story of ingenuity, ambition, and possibility in which the greater forces of progress and change are made by one of our most humble and ubiquitous objects.

Available in PDF, EPUB and Kindle. Book excerpt: "Life Is Bottled Sunshine" [Wynwood Reade, Martyrdom of Man, 1924]. This inspired phrase is a four-word summary of the significance of photosynthesis for life on earth. The study of photosynthesis has attracted the attention of a legion of biologists, biochemists, chemists and physicists for over 200 years. Discoveries in Photosynthesis presents a sweeping overview of the history of photosynthesis investigations, and detailed accounts of research progress in all aspects of the most complex bioenergetic process in living organisms. Conceived of as a way of summarizing the history of research advances in photosynthesis as of millennium 2000, the book evolved into a majestic and encyclopedic saga involving all of the basic sciences. The book contains 111 papers, authored by 132 scientists from 19 countries. It includes overviews; timelines; tributes; minireviews on excitation energy transfer, reaction centers, oxygen evolution, light-harvesting and pigment-protein complexes, electron transport and ATP synthesis, techniques and applications, biogenesis and membrane architecture, reductive and assimilatory processes, transport, regulation and adaptation, Genetics, and Evolution; laboratories and national perspectives; and retrospectives that end in a list of photosynthesis symposia, books and conferences. Informal and formal photographs of scientists make it a wonderful book to have. This book is meant not only for the researchers and graduate students, but also for advanced undergraduates in Plant Biology, Microbiology, Cell Biology, Biochemistry, Biophysics and History of Science.
Download or read book Hidden Costs of Energy written by National Research Council and published by National Academies Press. This book was released on 2010-05-26 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the many benefits of energy, most of which are reflected in energy market prices, the production, distribution, and use of energy causes negative effects. Many of these negative effects are not reflected in energy market prices. When market failures like this occur, there may be a case for government interventions in the form of regulations, taxes, fees, tradable permits, or other instruments that will motivate recognition of these external or hidden costs. The Hidden Costs of Energy defines and evaluates key external costs and benefits that are associated with the production, distribution, and use of energy, but are not reflected in market prices. The damage estimates presented are substantial and reflect damages from air pollution associated with electricity generation, motor vehicle transportation, and heat generation. The book also considers other effects not quantified in dollar amounts, such as damages from climate change, effects of some air pollutants such as mercury, and risks to national security. While not a comprehensive guide to policy, this analysis indicates that major initiatives to further reduce other emissions, improve energy efficiency, or shift to a cleaner electricity generating mix could substantially reduce the damages of external effects. A first step in minimizing the adverse consequences of new energy technologies is to better understand these external effects and damages. The Hidden Costs of Energy will therefore be a vital informational tool for government policy makers, scientists, and economists in even the earliest stages of research and development on energy technologies.

Available in PDF, EPUB and Kindle. Book excerpt: "The impact of technology on society is clear and unmistakeable. The influence of society on technology is more subtle. The 13 essays in this book have been written by a diverse group of scholars united by a common interest in creating a new field - the sociology of technology. They draw on a wide array of case studies - from cooking stoves to missile systems, from 15th-century Portugal to today's Al labs - to outline an original research program based on a synthesis of ideas from the social studies of science and the history of technology. Together they affirm the need for a study of technology that gives equal weight to technical, social, economic, and political questions"--Back cover.
Download or read book Flipped written by Wendelin Van Draanen and published by Ember. This book was released on 2003-05-13 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classic he-said-she-said romantic comedy! This updated anniversary edition offers story-behind-the-story revelations from author Wendelin Van Draanen. The first time she saw him, she flipped. The first time he saw her, he ran. That was the second grade, but not much has changed by the seventh. Juli says: “My Bryce. Still walking around with my first kiss.” He says: “It’s been six years of strategic avoidance and social discomfort.” But in the eighth grade everything gets turned upside down: just as Bryce is thinking that there’s maybe more to Juli than meets the eye, she’s thinking that he’s not quite all he seemed. This is a classic romantic comedy of errors told in alternating chapters by two fresh, funny voices. The updated anniversary edition contains 32 pages of extra backmatter: essays from Wendelin Van Draanen on her sources of inspiration, on the making of the movie of Flipped, on why she’ll never write a sequel, and a selection of the amazing fan mail she’s received. Awards and accolades for Flipped: SLJ Top 100 Children’s Novels of all time IRA-CBC Children’s Choice IRA Teacher’s Choice Honor winner, Judy Lopez Memorial Award/WNBA Winner of the California Young Reader Medal “We flipped over this fantastic book, its gutsy girl Juli and its wise, wonderful ending.” — The Chicago Tribune “Van Draanen has another winner in this eighth-grade ‘he-said, she-said’ romance. A fast, funny, egg-cellent winner.” — SLJ, Starred review “With a charismatic leading lady kids will flip over, a compelling dynamic between the two narrators and a resonant ending, this novel is a great deal larger than the sum of its parts.” —Publishers Weekly, Starred review
