Download or read book Radiation Trapping in Atomic Vapours written by Andreas F. Molisch and published by Oxford University Press. This book was released on 1998 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation can be absorbed and re-emitted many times in atomic vapors before it reaches the boundaries of the container encasing the vapor. This effect is known as radiation trapping. It plays an important role practically everywhere atomic vapors occur, whether in spectroscopy, gas lasers, atomic line filters, the determination of atomic lifetimes, measurements of atomic interaction potentials, or electric discharge lamps. This book is the first to assemble all of the information necessary to handle practical problems related to radiation trapping, and it emphasizes both physical insights and mathematical methods. The introduction reviews resonance radiation and collision processes in atomic vapors. This is followed by detailed explanations of the physical effects and mathematical methods for various types of problems (e.g., with or without saturation, particle diffusion, reflecting cell walls). The last part of the book describes the applications of these methods to a variety of practical problems, such as cross-section measurements and the design of discharge lamps.

Download or read book Optical Trapping and Manipulation of Neutral Particles Using Lasers written by Arthur Ashkin and published by World Scientific Publishing Company Incorporated. This book was released on 2006 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important volume contains selected papers and extensive commentaries on laser trapping and manipulation of neutral particles using radiation pressure forces. Such techniques apply to a variety of small particles, such as atoms, molecules, macroscopic dielectric particles, living cells, and organelles within cells. These optical methods have had a revolutionary impact on the fields of atomic and molecular physics, biophysics, and many aspects of nanotechnology.In atomic physics, the trapping and cooling of atoms down to nanokelvins and even picokelvin temperatures are possible. These are the lowest temperatures in the universe. This made possible the first demonstration of Bose-Einstein condensation of atomic and molecular vapors. Some of the applications are high precision atomic clocks, gyroscopes, the measurement of gravity, cryptology, atomic computers, cavity quantum electrodynamics and coherent atom lasers.A major application in biophysics is the study of the mechanical properties of the many types of motor molecules, mechanoenzymes, and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Unique in vitro and in vivo assays study the driving forces, stepping motion, kinetics, and efficiency of these motors as they move along the cell's cytoskeleton. Positional and temporal resolutions have been achieved, making possible the study of RNA and DNA polymerases, as they undergo their various copying, backtracking, and error correcting functions on a single base pair basis.Many applications in nanotechnology involve particle and cell sorting, particle rotation, microfabrication of simple machines, microfluidics, and other micrometer devices. The number of applications continues to grow at a rapid rate.The author is the discoverer of optical trapping and optical tweezers. With his colleagues, he first demonstrated optical levitation, the trapping of atoms, and tweezer trapping and manipulation of living cells and biological particles.This is the only review volume covering the many fields of optical trapping and manipulation. The intention is to provide a selective guide to the literature and to teach how optical traps really work.

Book excerpt: NATIONAL BESTSELLER | NEW YORK TIMES NOTABLE BOOK OF THE YEAR. From an eminent international security scholar, an urgent examination of the conditions that could produce a catastrophic conflict between the United States and China—and how it might be prevented. China and the United States are heading toward a war neither wants. The reason is Thucydides’s Trap: when a rising power threatens to displace a ruling one, violence is the likeliest result. Over the past five hundred years, these conditions have occurred sixteen times; war broke out in twelve. At the time of publication, an unstoppable China approached an immovable America, and both Xi Jinping and Donald Trump promised to make their countries “great again,” the seventeenth case was looking grim—it still is. A trade conflict, cyberattack, Korean crisis, or accident at sea could easily spark a major war. In Destined for War, eminent Harvard scholar Graham Allison masterfully blends history and current events to explain the timeless machinery of Thucydides’s Trap—and to explore the painful steps that might prevent disaster today.

Book excerpt: Camera trapping in wildlife management and research is a growing global phenomenon. The technology is advancing very quickly, providing unique opportunities for collecting new biological knowledge. In order for fellow camera trap researchers and managers to share their knowledge and experience, the First International Camera Trapping Colloquium in Wildlife Management and Research was held in Sydney, Australia. Camera Trapping brings together papers from a selection of the presentations at the colloquium and provides a benchmark of the international developments and uses of camera traps for monitoring wildlife for research and management. Four major themes are presented: case studies demonstrating camera trapping for monitoring; the constraints and pitfalls of camera technologies; design standards and protocols for camera trapping surveys; and the identification, management and analyses of the myriad images that derive from camera trapping studies. The final chapter provides future directions for research using camera traps. Remarkable photographs are included, showing interesting, enlightening and entertaining images of animals 'doing their thing'.
Download or read book Introduction to Light Trapping in Solar Cell and Photo detector Devices written by Stephen Fonash and published by Academic Press. This book was released on 2014-09-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Approaches to Light Trapping in Solar Cell Devices discusses in detail the use of photonic and plasmonic effects for light trapping in solar cells. It compares and contrasts texturing, the current method of light-trapping design in solar cells, with emerging approaches employing photonic and plasmonic phenomena. These new light trapping methods reduce the amount of absorber required in a solar cell, promising significant cost reduction and efficiency. This book highlights potential advantages of photonics and plasmonics and describes design optimization using computer modeling of these approaches. Its discussion of ultimate efficiency possibilities in solar cells is grounded in a review of the Shockley-Queisser analysis; this includes an in-depth examination of recent analyses building on that seminal work.
Download or read book The Ant Trap written by Brian Epstein and published by . This book was released on 2015 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in a world of crowds and corporations, artworks and artifacts, legislatures and languages, money and markets. These are all social objects - they are made, at least in part, by people and by communities. But what exactly are these things? How are they made, and what is the role of people in making them? In The Ant Trap, Brian Epstein rewrites our understanding of the nature of the social world and the foundations of the social sciences. Epstein explains and challenges the three prevailing traditions about how the social world is made. One tradition takes the social world to be built out of people, much as traffic is built out of cars. A second tradition also takes people to be the building blocks of the social world, but focuses on thoughts and attitudes we have toward one another. And a third tradition takes the social world to be a collective projection onto the physical world. Epstein shows that these share critical flaws. Most fundamentally, all three traditions overestimate the role of people in building the social world: they are overly anthropocentric. Epstein starts from scratch, bringing the resources of contemporary metaphysics to bear. In the place of traditional theories, he introduces a model based on a new distinction between the grounds and the anchors of social facts. Epstein illustrates the model with a study of the nature of law, and shows how to interpret the prevailing traditions about the social world. Then he turns to social groups, and to what it means for a group to take an action or have an intention. Contrary to the overwhelming consensus, these often depend on more than the actions and intentions of group members.

Download or read book Trapping and the Detection Control and Regulation of Tephritid Fruit Flies written by Todd Shelly and published by Springer. This book was released on 2014-10-06 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on four broad topics related to trapping of agriculturally important tephritid fruit flies, namely i) lures and traps, ii) invasion biology and detection of infestations, iii) attract and kill systems, and iv) trade regulations and risk assessment. This comprehensive structure progresses from the biological interaction between insect and lures/traps to the area-wide use of trapping systems to the utilization and impact of trapping data on international trade. The chapters include accounts of earlier research but are not simply compendia and instead evaluate past and current work as a tool for critical analysis and proposal of productive avenues for future work. At present there is no book available that deals with fruit fly trapping in such a broad context. Our book fills this gap and serves as a global reference for both those interested in fruit flies specifically as well as anyone dealing with the threat of invasive agricultural insects in general.
