Buch. Zustand: Neu. Neuware - Combustion under sufficiently fuel-lean conditions can have the desirable attributes of high efficiency and low emissions, this being particularly important in light of recent and rapid increases in the cost of fossil fuels and concerns over the links between combustion and global climate change. Lean Combustion is an eminently authoritative, reference work on the latest advances in lean combustion technology and systems. It will offer engineers working on combustion equipment and systems both the fundamentals and the latest developments in more efficient fuel usage and in much-sought-after reductions of undesirable emissions, while still achieving desired power output and performance. This volume brings together research and design of lean combustion systems across the technology spectrum in order to explore the state-of-the-art in lean combustion and its role in meeting current and future demands on combustion systems. Readers will learn about advances in the understanding of ultra lean fuel mixtures and how new types of burners and approaches to managing heat flow can reduce problems often found with lean combustion such as slow, difficult ignition and frequent flame extinction. The book will also offer abundant references and examples of recent real-world applications.…

Buch. Zustand: Neu. Neuware - The 20th century has experienced environmental changes that appear to be unprecedented in their rate and magnitude during the Earth's history. For the first time, Stable Isotopes as Indicators of Ecological Change brings together a wide range of perspectives and data that speak directly to the issues of ecological change using stable isotope tracers. The information presented originates from a range of biological and geochemical sources and from research fields within biological, climatological and physical disciplines covering time-scales from days to centuries. Unlike any other reference, editors discuss where isotope data can detect, record, trace and help to interpret environmental change.…

Buch. Zustand: Neu. Neuware - In Chapter 1 Dudley Creagh writes on 'synchrotron radiation and its use in art, archaeometry, and cultural heritage studies'. Loic Bertrand has written in Chapter 2 on synchrotron imaging for archaeology and art history, conservation, and palaeontology. Dr. Bertrand is Archaeology and cultural heritage officer at the new French synchrotron, Synchrotron Soleil (Orme les Mesuriers, Gif-sur-Yvette, France). He is charged with the task of raising the awareness of cultural heritage scientists to the use of synchrotron radiation for their research. Chapter 3 has been written by Ivan Cole and his associates Dr David Paterson and Deborah Lau. This is concerned with the holistic modelling of gas and aerosol deposition and the degradation of cultural objects. Dr. Cole is Deputy Chief of the Novel Materials and Processes Division of the Commonwealth Scientific and Industrial Research Organization (Melbourne, Australia). He has over twenty years experience in involvement in projects concerned with the preservation of cultural heritage. Ivan is an internationally recognized leader in the field of the life cycle of materials and the development of protective coatings for metals. In Chapter 4, Giovanna Di Pietro describes two different types of experiments she has undertaken in the study of the mechanisms underlying the degradation of photographic media. In the first Dr. Di Pietro describes the degradation of old back-and-white plate. In the second she outlines her attempts to understand the mechanisms by which comparatively modern motion picture film degrades. A significant part of this project involved trying to ascertain exactly what dyes were used by Kodak in their motion picture film from about 1980 onwards. An entirely new technique for the remote investigation of the pigments in paintings is presented by Maria Kubik in Chapter 5. This technique will significantly enhance the ability of conservators to study the palette of pigments used by artists, check for repairs by others, and detect fraudulent paintings.…

Buch. Zustand: Neu. Neuware - Forensic Neuropathology provides superior visual examples of the more commonly encountered conditions in forensic neuropathology and answers questions that arise regarding neuropathological findings. The work includes values for frequently-encountered clinical assessments, and contains a more comprehensive summary of aging/dating of various neuropathological processes than is available in any other single current source. General pathology residents, forensic pathology and neuropathology fellows, and general pathologists and clinicians involved in referred cases will find this book extremely useful, as will individuals in allied fields such as law enforcement officers and attorneys. Forensic Neuropathology aims to: (1) provide a concise summary of practical information frequently needed in forensic neuropathology cases; (2) include selected material previously known but perhaps not significantly emphasized in current literature; and (3) where possible, to suggest aging/dating parameters for certain neuropathological findings relevant to forensic neuropathology testimony. As a selective reference, the volume emphasizes practical issues and focuses on the most commonly encountered issues among neuropathology and medical examiner professionals.…

Buch. Zustand: Neu. Neuware - Optical spectroscopy has been instrumental in the discovery of many lanthanide elements. In return, these elements have always played a prominent role in lighting devices and light conversion technologies (Auer mantles, incandescent lamps, lasers, cathode-ray and plasma displays). They are also presently used in highly sensitive luminescent bio-analyses and cell imaging. This volume of the Handbook on the Physics and Chemistry of Rare Earths is entirely devoted to the photophysical properties of these elements. It is dedicated to the late Professor William T (Bill) Carnall who has pioneered the understanding of lanthanide spectra in the 1960's and starts with a Dedication to this scientist. The following five chapters describe various aspects of lanthanide spectroscopy and its applications. Chapters 231 presents state-of-the-art theoretical calculations of lanthanide energy levels and transition intensities. It is followed by a review (Chapter 232) on both theoretical and experimental aspects of f-d transitions, a less well known field of lanthanide spectroscopy, yet very important for the design of new optical materials. Chapter 233 describes how confinement effects act on the photophysical properties of lanthanides when they are inserted into nanomaterials, including nanoparticles, nanosheets, nanowires, nanotubes, insulating and semiconductor nanocrystals. The use of lanthanide chelates for biomedical analyses is presented in Chapter 234; long lifetimes of the excited states of lanthanide ions allow the use of time-resolved spectroscopy, which leads to highly sensitive analyses devoid of background effect from the autofluorescence of the samples. The last review (Chapter 235) provides a comprehensive survey of near-infrared (NIR) emitting molecular probes and devices, spanning an all range of compounds, from simple chelates to macrocyclic complexes, heterometallic functional edifices, coordination polymers and other extended structures. Applications ranging from telecommunications to light-emitting diodes and biomedical analyses are assessed.…
