O livro intitulado Espectroscopia de Ressonância Magnética Nuclear é um texto atualizado destinado a químicos mas acessível a não especialistas que necessitem de alguns conhecimentos fundamentais desta hoje importantíssima técnica. O trabalho constitui uma atualização de um primeiro trabalho dos mesmos autores publicado alguns anos atrás, tendo em conta a importante evolução instrumental bem como das técnicas bidimensionais. Os autores esperam com este novo trabalho ter colocado à disposição dos leitores um trabalho que satisfaz os principais requisitos atuais de quem precisa da espectroscopia de ressonância magnética nuclear como um método de suporte à resolução de problemas estruturais.

This volume reflects on the unique status of the Western Mediterranean in the Bronze Age, considering the independence of its development and the existence of an indigenous maritime trade.

This is a new, basic introduction to polymer science. It is both comprehensive and readable. The authors are leading educators in this field with extensive backgrounds in industrial and academic polymer research. The text starts with a description of the types of microstructures found in polymer materials. This provides an understanding of some of the key features of the various mechanisms of homopolymerization and copolymerization which are discussed in following chapters. Also discussed in these chapters are the kinetics and statistics of polymerization, with a separate chapter on the characterization of chain structure by spectroscopic methods. The next part of the text deals with chain conformation, structure and morphology, leading to a discussion of crystallization, melting and glass transition. The discussion then moves from solid state to solution properties where solution thermodynamics is introduced. This provides the basis for discussion of the measurement of molecular weight by various solution methods. The final chapter deals with mechanical and rheological properties which are discussed from a phenomenological continuum approach and then in terms of a fundamental molecular perspective. Altogether, this new text provides a comprehensive, readable introduction to and overview of polymer science. It is well illustrated with schematics prepared for this text to help in the understanding of key concepts. It will provide a basic understanding of today's polymer science for technical and engineering personnel not already familiar with the subject, and a convenient update and overview for materials scientists.

This dictionary includes some 9200 terms, each with a definition and often and additional descriptive text in English, the terms being translated in French, German and Spanish. It is more complete than similar previously published dictionaries or glossaries, and contains all fields of soil science as well as some adjacent fields of other earth sciences, agriculture and engineering. Present concepts and definitions are detailed along with earlier concepts, not only for historical reasons but also for developing new ideas. Concepts, terms and definitions usual in literature of various countries are discussed and compared, to offer an appropriate exchange of ideas. Soil classifications and methodologies for soil investigation coming from a score of European, American and other countries and international organisations are presented, and correlations between names of soil taxa in different classifications are suggested. Readers active in all branches of soil science will find accessible answers to many of their questions, either directly referring to procedures used in the organisations where they work, or related to way of thinking in other countries. Readers active in other branches, but needing information on soils, will also find answers to this dictionary of great assistance to their research.* Over 9200 terms with definitions in English and translations in French, German, Spanish* Includes all fields of soil science and many connected sciences* All present-day terminology with inclusion of earlier, classical concepts and terms * Terminology in current USDA Soil Taxonomy, FAO World Reference Base or Soil Resources, and other documents from different countriesGranted the "N.Cernescu" award from the Romanian Academy on Agricultural and Forestry Sciences

"Surgical Management of Obesity" has been translated into Spanish. This brand-new resource presents the most comprehensive coverage of bariatric surgery. Individual chapters present the best surgical approaches, their outcomes, and other considerations involved.

Thinking Spanish Translation is a comprehensive and revolutionary 20-week course in translation method with a challenging and entertaining approach to the acquisition of translation skills.

Thinking Spanish Translationis a comprehensive and revolutionary 20-week course in translation method offering a challenging and entertaining approach to the acquisition of translation skills. It has been fully and successfully piloted at the University of St.Andrews. Translation is presented as a problem-solving discipline. Discussion, examples and a full range of exercise work enable students to acquire the skills necessary for a broad range of translation problems. Examples are drawn from a wide variety of material from technical and commercial texts to poetry and song. Thinking Spanish Translationis essential reading for advanced undergraduates and postgraduate students of Spanish. The book will also appeal to a wide range of languages students and tutors through the general discussion of principles, purposes and practice of translation.

This volume, as the seventh of the series Medicinal and Aromatic Plants of the World, deals with the medicinal and aromatic plant (MAPs) treasures of the so-called Southern Cone, the three southernmost countries (Argentina, Chile and Uruguay) of South America. Similarly to the previous volumes of the series, the main focus is to collect and provide information on major aspects of botany, traditional usage, chemistry, production / collection practices, trade and utilization of this specific group of plants. The contributors, who are recognized professionals and specialist of the domain, have collected and present state of the art information on 41 species. Most of these are not only of interest from the scientific point of view, but hold also a potential for the prospective utilization of the decreasing, occasionally overexploited / endangered medicinal plant resources of this huge continent. The book is expected to serve as a source of information also on some less known or less studied species. As such the volume is expected to support future research and public health professionals.
