Download or read book Light Matter Interaction written by John Weiner and published by Oxford University Press. This book was released on 2013 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book draws together the essential elements of classical electrodynamics, surface wave physics, plasmonic materials, and circuit theory of electrical engineering to provide insight into the essential physics of nanoscale light-matter interaction and to provide design methodology for practical nanoscale plasmonic devices. A chapter on classical and quantal radiation also highlights the similarities (and differences) between the classical fields of Maxwell's equations and the wave functions of Schrödinger's equation. The aim of this chapter is to provide a semiclassical picture of atomic absorption and emission of radiation, lending credence and physical plausibility to the "rules" of standard wave-mechanical calculations. The structure of the book is designed around five principal chapters, but many of the chapters have extensive "complements" that either treat important digressions from the main body or penetrate deeper into some fundamental issue. Furthermore, at the end of the book are several appendices to provide readers with a convenient reference for frequently-occurring special functions and explanations of the analytical tools, such as vector calculus and phasors, needed to express important results in electromagnetics and waveguide theory.

Download or read book Light Based Therapies for Skin of Color written by Elma Baron and published by Springer Science & Business Media. This book was released on 2009-06-12 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light-based therapies have been a major component of dermatologic practice. Historically, these treatment modalities have been mainly tailored to the treatment of patients with light skin. Principles governing use of light therapies in skin of color are less defined. However, there is a tremendous need to understand the benefits and limitations of these therapeutic options for dark-skinned patients as well. Demographic data in the United States alone indicate that the population and recipients of health care are rapidly changing with regard to skin phototype. Physicians who are involved in the delivery of care for patients with cutaneous problems that can be addressed by light treatments need to be able to fully understand the mechanisms, applications, risks, efficacy, adverse events, and other pertinent issues in considering treatment options for their patients with pigmented skin.

Download or read book Light and Shadow written by Michael L. Galaty and published by Cotsen Institute of Archaeology Press. This book was released on 2013-12-31 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employing survey archaeology, excavation, ethnographic study, and multinational archival work, the Shala Valley Project uncovered the many powerful, creative ways whereby the men and women of Shala shaped their world: through dynamic, world-systemic relationships with the powers that surrounded but never fully conquered them. The Shala Valley Project presents the highlanders, the malesore, in the full complexity of their lives, while also unveiling a new, deeper history for the region--a history that reaches back to an unexpected fortified Iron Age site. Light and Shadow tells many stories. Archaeologists, historians, and students of tribes, of empires, of imperial-indigenous relations, of blood feud, of kinship, of the built landscape, of world-systems theory and sustainability science, and more, will find much here to digest. The people of Shala, to which Light and Shadow is dedicated, may serve as an example in our modern age, one in which persistent, tribal peoples still fight for their survival, and seek to preserve some degree of independence from capitalist economies bent on their incorporation.

Download or read book The Optical Clearing Method written by Luís Manuel Couto Oliveira and published by Springer Nature. This book was released on 2019-11-27 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the Optical Immersion Clearing method and its application to acquire information with importance for clinical practice and various fields of biomedical engineering. The method has proved to be a reliable means of increasing tissue transparency, allowing the investigator or surgeon to reach deeper tissue layers for improved imaging and laser surgery. This result is obtained by partial replacement of tissue water with an active optical clearing agent (OCA) that has a higher refractive index and is a better match for the refractive index of other tissue components. Natural tissue scattering is thereby reduced. An exponential increase in research using this method has occurred in recent years, and new applications have emerged, both in clinical practice and in some areas of biomedical engineering. Recent research has revealed that treating ex vivo tissues with solutions containing active OCAs in different concentrations produces experimental data to characterize drug delivery or to discriminate between normal and pathological tissues. The obtained drug diffusion properties are of interest for the pharmaceutical and organ preservation industry. Similar data can be estimated with particular interest for food preservation. The free water content evaluation is also of great interest since it facilitates the characterization of tissues to discriminate pathologies. An interesting new application that is presented in the book regards the creation of two optical windows in the ultraviolet spectral range through the application of the immersion method. These induced transparency windows open the possibility to diagnose and treat pathologies with ultraviolet light. This book presents photographs from the tissues we have studied and figures that represent the experimental setups used. Graphs and tables are also included to show the numerical results obtained in the sequential calculations performed.
Download or read book Living Color written by Nina G. Jablonski and published by Univ of California Press. This book was released on 2012-09-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living Color is the first book to investigate the social history of skin color from prehistory to the present, showing how our body’s most visible trait influences our social interactions in profound and complex ways. In a fascinating and wide-ranging discussion, Nina G. Jablonski begins with the biology and evolution of skin pigmentation, explaining how skin color changed as humans moved around the globe. She explores the relationship between melanin pigment and sunlight, and examines the consequences of rapid migrations, vacations, and other lifestyle choices that can create mismatches between our skin color and our environment. Richly illustrated, this book explains why skin color has come to be a biological trait with great social meaning— a product of evolution perceived by culture. It considers how we form impressions of others, how we create and use stereotypes, how negative stereotypes about dark skin developed and have played out through history—including being a basis for the transatlantic slave trade. Offering examples of how attitudes about skin color differ in the U.S., Brazil, India, and South Africa, Jablonski suggests that a knowledge of the evolution and social importance of skin color can help eliminate color-based discrimination and racism.

Download or read book Interaction Ritual Chains written by Randall Collins and published by Princeton University Press. This book was released on 2014-05-06 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex, smoking, and social stratification are three very different social phenomena. And yet, argues sociologist Randall Collins, they and much else in our social lives are driven by a common force: interaction rituals. Interaction Ritual Chains is a major work of sociological theory that attempts to develop a "radical microsociology." It proposes that successful rituals create symbols of group membership and pump up individuals with emotional energy, while failed rituals drain emotional energy. Each person flows from situation to situation, drawn to those interactions where their cultural capital gives them the best emotional energy payoff. Thinking, too, can be explained by the internalization of conversations within the flow of situations; individual selves are thoroughly and continually social, constructed from the outside in. The first half of Interaction Ritual Chains is based on the classic analyses of Durkheim, Mead, and Goffman and draws on micro-sociological research on conversation, bodily rhythms, emotions, and intellectual creativity. The second half discusses how such activities as sex, smoking, and social stratification are shaped by interaction ritual chains. For example, the book addresses the emotional and symbolic nature of sexual exchanges of all sorts--from hand-holding to masturbation to sexual relationships with prostitutes--while describing the interaction rituals they involve. This book will appeal not only to psychologists, sociologists, and anthropologists, but to those in fields as diverse as human sexuality, religious studies, and literary theory.
