Sol-gel processing is a low temperature, low cost wet chemistry route to a range of different materials, particularly glassy and ceramic oxides, including nanoparticles and powders, fibers, thin films and membranes, or monoliths and composites. Thin films and coatings represent by far the most important category of sol-gel derived products with optical, electronic and magnetic functionalities, for example photoresist and dielectric spin-on-glass layers, flat screen displays, anti-reflection, conducting and magnetic disk coatings, as well as photochromic, electrochromic and photovoltaic coatings. Sol-gel derived materials are homogeneous at the molecular level and are a good example of a bottom-up approach to materials synthesis. There is increasing need of new optical and photonic materials with improved performance, where molecular level homogeneity and easy fabrication in film form may be especially convenient, highlighting a decisive advantage of sol-gel over other more established technologies to obtain graded index optical components, solar control coatings, phosphors, glass ceramics or multilayer photonic structures.

There is no book available yet which focuses in particular on optical and photonic sol-gel derived materials. This is what makes this book unique at this point for those especially or exclusively interested in optical and photonic functional materials and applications. This book represents an important tool to update scientists and engineers with recent advances in the rapidly evolving field of optical and photonic materials, components and devices. Our target audience are those working in materials science, physics, engineering and chemistry disciplines, in particular academics and researchers working in advanced optical/photonic processing technologies, research and development engineers in high technology industries and research project leaders. This book will also be an essential tool for graduate students pursuing a PhD or even a Master's degree.

Complementing a burgeoning area of interest and academic study, Roc the Mic Right explores the central role of language within the Hip Hop Nation (HHN). With its status convincingly argued as the best means by which to read Hip Hop culture, H. Samy Alim then focuses on discursive practices, such as narrative sequencing and ciphers, or lyrical circles of rhymers. Often a marginalized phenomenon, the complexity and creativity of Hip Hop lyrical production is emphasised, whilst Alim works towards the creation of a schema by which to understand its aesthetic.Using his own ethnographic research, Alim shows how Hip Hop language could be used in an educational context and presents a new approach to the study of the language and culture of the Hip Hop Nation: 'Hiphopography'. The final section of the book, which includes real conversational narratives from Hip Hop artists such as The Wu-Tang Clan and Chuck D, focuses on direct engagement with the language.A highly accessible and lively work on the most studied and read about language variety in the United States, this book will appeal not only to language and linguistics researchers and students, but holds a genuine appeal to anyone interested in Hip Hop or Black African Language.

Kombucha: Technology, Traceability, and Health-Promoting Effects covers both conventional and unconventional sources for the development of kombucha analogues, along with their sensory, functional, and nutritional aspects. Topics include process conditions, their escalation and impact on the chemical composition, the biochemistry to produce scoby, and the functionality of the drinks. Regulatory aspects in different countries, as well as myths and realities of kombucha’s bioactivities, are also covered. Users will find a great resource that also documents the probiotic potential of this popular drink, highlighting metabiotics, nutribiotics, and the pharmabiotics present.This book will serve as a valuable resource for researchers in food science and beverage science, especially those interested in fermentation.

Includes aspects of technology and scaling to obtain kombucha and its analogues, as well as the development of a biofilm (scoby)Summarizes the biochemical aspects involved in the process of creating fermented beveragesDiscusses regulatory aspects and as well as health claims, separating myth from fact

Signal detection theory--as developed in electrical engineering and based on statistical decision theory--was first applied to human sensory discrimination 40 years ago. The theoretical intent was to provide a valid model of the discrimination process; the methodological intent was to provide reliable measures of discrimination acuity in specific sensory tasks. An analytic method of detection theory, called the relative operating characteristic (ROC), can isolate the effect of the placement of the decision criterion, which may be variable and idiosyncratic, so that a pure measure of intrinsic discrimination acuity is obtained. For the past 20 years, ROC analysis has also been used to measure the discrimination acuity or inherent accuracy of a broad range of practical diagnostic systems. It was widely adopted by methodologists in the field of information retrieval, is increasingly used in weather forecasting, and is the generally preferred method in clinical medicine, primarily in radiology. This book attends to both themes, ROC analysis in the psychology laboratory and in practical diagnostic settings, and to their essential unity. The focus of this book is on detection and recognition as fundamental tasks that underlie most complex behaviors. As defined here, they serve to distinguish between two alternative, confusable stimulus categories, which may be perceptual or cognitive categories in the psychology laboratory, or different states of the world in practical diagnostic tasks.This book on signal detection theory in psychology was written by one of the developers of the theory, who co-authored with D.M. Green the classic work published in this area in 1966 (reprinted in 1974 and 1988). This volume reviews the history of the theory in engineering, statistics, and psychology, leading to the separate measurement of the two independent factors in all discrimination tasks, discrimination acuity and decision criterion. It extends the previous book to show how in several areas of psychology--in vigilance and memory--what had been thought to be discrimination effects were, in reality, effects of a changing criterion. The book shows that data plotted in terms of the relative operating characteristic have essentially the same form across the wide range of discrimination tasks in psychology. It develops the implications of this ROC form for measures of discrimination acuity, pointing up the valid ones and identifying several common, but invalid, ones. The area under the binormal ROC is seen to be supported by the data; the popular measures d' and percent correct are not. An appendix describes the best, current programs for fitting ROCs and estimating their parameters, indices, and standard errors. The application of ROC analysis to diagnostic tasks is also described. Diagnostic accuracy in a wide range of tasks can be expressed in terms of the ROC area index. Choosing the appropriate decision criterion for a given diagnostic setting--rather than considering some single criterion to be natural and fixed--has a major impact on the efficacy of a diagnostic process or system. Illustrated here by separate chapters are diagnostic systems in radiology, information retrieval, aptitude testing, survey research, and environments in which imminent dangerous conditions must be detected. Data from weather forecasting, blood testing, and polygraph lie detection are also reported. One of these chapters describes a general approach to enhancing the accuracy of diagnostic systems.
