Synoptic meteorology, the study of large-scale weather systems and forecasting using observation, and dynamic meteorology, the study of the laws of physics involved in air movement, are treated in this major new text in two volumes. The author, a meteorologist noted for his research on tornadoes and severe storms, based his work on material he has taught for the past 14 years at the University of Oklahoma. There are no modern texts on the topic. Volume II covers the formation, motion and climatology of extratropical weather systems in the context of the quasigeostrophic theory and "IPV" thinking, the formation and structure of fronts and jets, applications of semigeostrophic theory, and the observed structure and dynamics of precipitation systems in midlatitudes.

Nueva edición de una obra única dentro de este campo, que abarca con su contenido el programa completo de la asignatura de Citología e histología vegetal y animal. NOVEDADES DE LA CUARTA EDICIÓN: Se han reelaborado y actualizado todos los temas. Dicha revision ha supuesto cambios en la estructura interna de los capitulos, que subrayan las conexiones entre la morfologia clasica y el avance constante en los conocimientos funcionales. Para ofrecer una vision completa de la celula, se han incluido aspectos propiamente moleculares, como las señales entre celulas y la regulacion del ciclo celular. Tambien se ha procurado resaltar algunos aspectos de la biologia comparada en el apartado de histologia, e introducir conceptos mas practicos en el apartado de histologia vegetal. En el apartado de Histologia vegetal se ha mejorado el texto que relaciona la estructura con la funcion, para darle un caracter mas funcional y no solo morfologico. Todo ello ha llevado a renovar parte de la iconografia, basada en micrografias de microscopia optica y electronica, esquemas y dibujos a todo color que facilitan y simplifican la comprension del texto. Se ha hecho tambien un esfuerzo por proporcionar al lector un resumen de la bibliografia mas apropiada para profundizar en los diferentes aspectos tratados. Se ha añadido un apendice con el significado de las siglas utilizadas a lo largo del texto.

With the demands of quality management and process control in an industrial environment machine vision is becoming an important issue. This handbook of machine vision is written by experts from leading companies in this field. It goes through all aspects of image acquisition and image processing. From the viewpoint of the industrial application the authors also elucidate in topics like illumination or camera calibration. Attention is paid to all hardware aspects, starting from lenses and camera systems to camera computer interfaces. Besides the detailed hardware descriptions the necessary software is discussed with equal profoundness. This includes sections on digital image basics as well as image analysis and image processing. Finally the user is introduced to general aspects of industrial applications of machine vision, such as case studies and strategies for the conception of complete machine vision systems. With this handbook the reader will be enabled not only to understand up to date systems for machine vision but will also be qualified for the planning and evaluation of such technology.

A comprehensive, unified treatment of present-day nuclear physics-the fresh edition of a classic text/reference."A fine and thoroughly up-to-date textbook on nuclear physics . . . most welcome." -Physics Today (on the First Edition).What sets Introductory Nuclear Physics apart from other books on the subject is its presentation of nuclear physics as an integral part of modern physics. Placing the discipline within a broad historical and scientific context, it makes important connections to other fields such as elementary particle physics and astrophysics.Now fully revised and updated, this Second Edition explores the changing directions in nuclear physics, emphasizing new developments and current research-from superdeformation to quark-gluon plasma. Author Samuel S.M. Wong preserves those areas that established the First Edition as a standard text in university physics departments, focusing on what is exciting about the discipline and providing a concise, thorough, and accessible treatment of the fundamental aspects of nuclear properties.

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect.With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered.FeaturesExplores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of:1,4-Dioxane (mature in its emerging contaminant life cycle)Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant)Hexavalent chromium (former emerging contaminant with evolving science)1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle)Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.
