Las guerras del agua. Privatización, contaminación y lucro
by Vandana Shivasociedad para analizar la histórica erosión de los derechos de acceso al agua por parte de las comunidades humanas. Al analizar el comercio internacional del agua, incluyendo su embalsamiento y extracción, así como la acuicultura, Shiva pone al descubierto la destrucción de la tierra y la pérdida de derechos de los pobres del planeta, a medida que se les niega el acceso a un invaluable bien común. Vandana Shiva revela cómo muchos de los más importantes conflictos actuales a menudo enmascarados como guerras étnicas o religiosas, como el conflicto israelí-palestino, son de hecho disputas por recursos naturales escasos y necesarios. Las guerras del agua resalta la función espiritual y tradicional que el agua ha tenido en comunidades históricas, y alerta acerca de la privatización que amenaza culturas y formas de vida universales. Vandana Shiva es una de las pensadoras más dinámicas y provocadoras del mundo en temas relacionados con el medio ambiente, con los derechos de la mujer y con cuestiones internacionales. Física, ecologista y activista, en 1993 fue distinguida con el Right Livelihood Award, el Premio Nobel alternativo. Es directora de la Fundación para la Investigación de las Ciencias, la Tecnología y la Política de Recursos Naturales.

Laser - Surface Interactions
by Rashid A. GaneevThis book is about the interaction of laser radiation with various surfaces at variable parameters of radiation. As a basic principle of classification we chose the energetic or intensity level of interaction of laser radiation with the surfaces. These two characteristics of laser radiation are the most important parameters defining entire spectrum of the processes occurring on the surfaces during interaction with electromagnetic waves. This is a first book containing a whole spectrum of the laser-surface interactions distinguished by the ranges of used laser intensity. It combines the surface response starting from extremely weak laser intensities (~1 W cm-2) up to the relativistic intensities (~1020 W cm-2 and higher). The book provides the basic information about lasers and acquaints the reader with both common applications of laser-surface interactions (laser-related printers, scanners, barcode readers, discs, material processing, military, holography, medicine, etc) and unusual uses of the processes on the surfaces under the action of lasers (art conservation, rangefinders and velocimeters, space and earth explorations, surface engineering and ablation, and others). The scientific applications of laser-surfaces interactions (surface optical nonlinearities, surface enhanced Raman spectroscopy, surface nanostructuring, nanoripples and clusters formation, X-ray lasers and harmonic generation from the surfaces) are discussed from the point of view of the close relations between the properties of surface and matter, which is a cornerstone of most of studies of materials. The novelty of the approach developed in Laser - Surface Interactions is related with the interconnection of scientific studies with numerous applications of the laser-surface interactions separated in different chapters by the ranges of laser intensities. We present most recent achievements in this field. The book provides valuable information for different ranges of reader's preparedness to the laser-related topics (from unprepared readers, to students, engineers and researchers, professionals and academics).

Laser Cladding of Metals
by Pasquale CavaliereLaser cladding is an additive manufacturing technology capable of producing coatings due to the surface fusion of metals. The selected powder is fed into a focused laser beam to be melted and deposited as coating. This allows to apply material in a selected way onto those required sections of complex components. The process main properties are the production of a perfect metallurgically bonded and fully dense coatings; the minimal heat affected zone and low dilution between the substrate and filler material resulting in functional coatings that perform at reduced thickness, so fewer layers are applied; fine, homogeneous microstructure resulting from the rapid solidification rate that promotes wear resistance of carbide coatings; near net-shape weld build-up requires little finishing effort; extended weldability of sensitive materials like carbon-rich steels or nickel-based superalloys that are difficult or even impossible to weld using conventional welding processes; post-weld heat treatment is often eliminated as the small heat affected zone minimizes component stress; excellent process stability and reproducibility because it is numerical controlled welding process. The typical applications are the dimensional restoration; the wear and corrosion protection; additive manufacturing. The wide range of materials that can be deposited and its suitability for treating small areas make laser cladding particularly appropriate to tailor surface properties to local service requirements and it opens up a new perspective for surface engineered materials. The main key aspect to be scientifically and technologically explored are the type of laser; the powders properties; the processing parameters; the consequent microstructural and mechanical properties of the processed material; the capability of fabrication of prototypes to rapid tooling and rapid manufacturing.Distills critical concepts, methods, and applications from leading full-length chapters, along with the authors’s own deep understanding of the material taught, into a concise yet rigorous graduate and advanced undergraduate text;Reinforces concepts covered with detailed solutions to illuminating and challenging industrial applications;Discusses current and future applications of laser cladding in additive manufacturing.

Laser Desorption Ionization Mass Spectrometry Based on Nanophotonic Structure: From Material Design to Mechanistic Understanding (Springer Theses)
by Moon-Ju KimThis book presents innovative laser desorption ionization (LDI)-active nanophotonic structures for addressing the challenges that matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) is currently facing and for enhancing LDI efficiency. It presents a variety of cutting-edge nanophotonic structures to satisfy the mass-analytical needs of sensitivity, reproducibility, and quantification. As opposed to the commercialized, conventional organic matrix used in MALDI-MS, these nanostructures are validated to be highly effective in detecting small metabolites and drugs, highlighting their considerable potential in the mass spectrometry field. It also systematically elucidates fundamental LDI processes in terms of the photo-thermal, electronic, and structural characteristics of nanophotonic structures, offering mechanistic knowledge of LDI-MS. Even though LDI-MS performance is heavily influenced by a number of nanostructure parameters, relatively little is known about the LDI processes associated with those characteristics. An in-depth understanding of nanostructure characteristics and LDI mechanisms thus paves the way for more effective, rational design and development of nanostructures with improved LDI capabilities. Further, with a focus on multiple cascades in nanostructure functions in response to laser pulse stimuli, this book provides detailed, step-by-step procedures to design and construct a nanophotonic, LDI-active platform, which may serve as a roadmap for graduate students in the field of mass spectrometry. Readers, including graduate students, researchers, and experts working in the related areas of mass spectrometry, nanophotonics, and material science and material engineering, will find a wealth of useful information in this book.
