Book Description
The Eye: Volume 2, The Visual Process is a compendium of papers that describes the physiology of the eye, particularly the visual functions, the photobiology of the visual process, and the visual pathway. One paper describes the light stimuli used in physiological experiments concerning vision in terms of their spectral energy distribution, particularly the amounts of light absorbed by the photosensitive substances contained in the retinal receptors. Another paper explains the mosaic-like arrangement of the receptors and the variations of this mosaic in the different regions of the retina, including the Purkinje phenomenon which can cause errors in visual measurements. One paper examines the directional properties of the rods at long wavelengths and the theory of the Stiles-Crawford effect. Other papers investigate the limits of the visible spectrum, the scotopic luminous efficiency, theories of dark-adaptation, as well as the minimum retinal illumination, the minimum flux of energy, and the minimum amount necessary for vision. One paper notes that whereas one rod can be stimulated by one quantum (a discrete process involving one pigment molecule), it is not sufficient to make a human subject see a light stimulus. The compendium is invaluable for researchers and investigators involved in physiology, psychology, ophthalmology, and in all branches of ocular physiology.

Book Description
During the last ten to fifteen years, researchers have made considerable progress in the study of inorganic scintillators. New scintillation materials have been investigated, novel scintillation mechanisms have been discovered, and additional scintillator applications have appeared. Demand continues for new and improved scintillation materials for a variety of applications including nuclear and high energy physics, astrophysics, medical imaging, geophysical exploration, radiation detection, and many other fields. However, until now there have been no books available that address in detail the complex scintillation processes associated with these new developments. Now, a world leader in the theory and applications of scintillation processes integrates the latest scientific advances of scintillation into a new work, Physical Processes in Inorganic Scintillators. Written by distinguished researcher Piotr Rodnyi, this volume explores this challenging subject, explains the complexities of scintillation from a modern point of view, and illuminates the way to the development of better scintillation materials. This unique work first defines the fundamental physical processes underlying scintillation and governing the primary scintillation characteristics of light output, decay time, emission spectrum, and radiation hardness. The book then discusses the complicated mechanisms of energy conversion and transformation in inorganic scintillators. The section on the role of defects in energy transfer and scintillation efficiency will be of special interest. Throughout, the author does not offer complicated derivations of equations but, instead, presents useful equations with practical results.

Book Description
This volume makes a significant contribution to both the study of Derrida and of modernist studies. The contributors argue, first, that deconstruction is not modern; neither is it postmodern nor simply modernist. They also posit that deconstruction is intimately connected with literature, not because deconstruction would be a literary way of doing philosophy, but because literature stands out as a modern notion. The contributors investigate the nature and depth of Derrida's affinities with writers such as Joyce, Kafka, Antonin Artaud, Georges Bataille, Paul Celan, Maurice Blanchot, Theodor Adorno, Samuel Beckett, and Walter Benjamin, among others. With its strong connection between philosophy and literary modernism, this highly original volume advances modernist literary study and the relationship of literature and philosophy.

Book Description
During his lifetime, Dante was condemned as corrupt and banned from Florence on pain of death. But in 1329, eight years after his death, he was again viciously condemned—this time as a heretic and false prophet—by Friar Guido Vernani. From Vernani’s inquisitorial viewpoint, the author of the Commedia “seduced” his readers by offering them “a vessel of demonic poison” mixed with poetic fantasies designed to destroy the “healthful truth” of Catholicism. Thanks to such pious vituperations, a sulphurous fume of unorthodoxy has persistently clung to the mantle of Dante’s poetic fame. The primary critical purpose of Dante & the Unorthodox is to examine the aesthetic impulses behind the theological and political reasons for Dante’s allegory of mid-life divergence from the papally prescribed “way of salvation.” Marking the septicentennial of his exile, the book’s eighteen critical essays, three excerpts from an allegorical drama, and a portfolio of fourteen contemporary artworks address the issue of the poet’s conflicted relation to orthodoxy. By bringing the unorthodox out of the realm of “secret things,” by uncensoring them at every turn, Dante dared to oppose the censorious regime of Latin Christianity with a transgressive zeal more threatening to papal authority than the demonic hostility feared by Friar Vernani.

Book Description
Electrical Processes in Organic Thin Film Devices A one-stop examination of fundamental electrical behaviour in organic electronic device architectures In Electrical Processes in Organic Thin Film Devices: From Bulk Materials to Nanoscale Architectures, distinguished researcher Michael C. Petty delivers an in-depth treatment of the electrical behaviour of organic electronic devices focused on first principles. The author describes the fundamental electrical behaviour of various device architectures and offers an introduction to the physical processes that play a role in the electrical conductivity of organic materials. Beginning with band theory, the text moves on to address the effects of thin film device architectures and nanostructures. The book discusses the applications to devices currently in the marketplace, like displays, as well as those under development (transistors, solar cells, and memories). Electrical Processes in Organic Thin Film Devices also describes emerging organic thin film architectures and explores the potential for single molecule electronics and biologically inspired devices. Finally, the book also includes: A detailed introduction to electronic and vibrational states in organic solids, including classical band theory, disordered semiconductors, and lattice vibrations Comprehensive explorations of electrical conductivity, including electronic and ionic processes, carrier drift, diffusion, the Boltzmann Transport Equation, excess carriers, recombination, doping, and superconductivity An overview of important electro-active organic materials, like molecular crystals, charge-transfer complexes, conductive polymers, carbon nanotubes, and graphene Practical considerations of defects and nanoscale phenomena, including transport processes in low-dimensional systems, surfaces and interface states In-depth examinations of metal contacts, including ohmic contacts, the Schottky Barrier, and metal/molecule contacts A systematic guide to the operating principles of metal/insulator/semiconductor structures and the field effect A set of problems (with solutions on-line) for each chapter of the book Perfect for electronics developers and researchers in both industry and academia who study and work with molecular and nanoscale electronics, Electrical Processes in Organic Thin Film Devices also deserves a place in the libraries of undergraduate and postgraduate students in courses on molecular electronics, organic electronics, and plastic electronics.
