La durabilidad y el desempeño de capas de rodadura de pavimentos en concreto asfáltico dependen de múltiples factores. Aunque el control de calidad convencional evalúa la respuesta mecánica (capacidad portante y deformabilidad), hay características que no son debidamente estudiadas (composición química y mineralógica de los agregados pétreos; estructura interna del concreto asfáltico). Para complementar la evaluación de concretos asfálticos utilizados para pavimentación vial, se implementan técnicas poco convencionales en la ingeniería civil como los análisis petrográficos, mineralógicos y químicos. En este libro se exponen los aspectos más relevantes relacionados con el...
Las construcciones rurales, y en general las obras de infraestructura rural en países en vías de desarrollo, presentan ciertas características particulares del contexto: requieren grandes inversiones y su rentabilidad es baja; además, quienes deben implementarlas en su mayoría son personas de medianos a bajos recursos. Por otra parte, la dispersión de los sistemas productivos en pequeños terrenos aumenta los costos —si se compara con las grandes explotaciones intensivas de otras regiones— y, adicionalmente, la rentabilidad de su implementación depende de muchos aspectos técnicos, los cuales son difíciles de integrar. Estas características hacen que sea necesario conocer los fu...
Caracterización química, morfológica y estructural de materiales es una obra que está enfocada a la descripción de técnicas de caracterización de materiales sólidos. El libro brinda al lector la oportunidad de conocer los principios fisicoquímicos involucrados en las técnicas de caracterización que se abordan, ilustra sobre la configuración y funcionamiento de los equipos y finalmente describe los métodos de análisis adecuados para la obtención de información química, morfológica y estructural de los materiales. El libro describe técnicas usadas para determinar la composición química elemental de la superficie de una muestra como son la espectroscopia Auger y el análisi...
VI. The U.S role
This book is the standard reference manual of cancer registration methodology and uses. It provides guidelines on all aspects, such as the establishment of a registry, collection, coding, verification and analysis of data, and the uses to which cancer registry data may be put. Emphasis is on population-based registration, which provides information on a defined population and permits calculation of incidence rates. Such registries are useful in cancer epidemiology (identification of possible aetiological factors), in planning future health services, and in monitoring the effectiveness of cancer prevention and treatment.
Written for both researchers and advanced students, this Handbook provides a state-of-the-art survey of the field of Spanish linguistics. Balancing different theoretical perspectives among expert scholars, it provides an in-depth examination of all sub-fields of research in Hispanic linguistics, with a focus on recent advances.
Fundamental Astronomy is a well-balanced, comprehensive introduction to classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. This is the fifth edition of the successful undergraduate textbook and reference work. It has been extensively modernized and extended in the parts dealing with extragalactic astronomy and cosmology. You will also find augmented sections on the solar system and extrasolar planets as well as a new chapter on astrobiology. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference work for dedicated amateur astronomers.
Winner of the Montserrat Ordóñez Prize 2018 This book provides an original and exciting analysis of Colombian women’s writing and its relationship to feminist history from the 1970s to the present. In a period in which questions surrounding women and gender are often sidelined in the academic arena, it argues that feminism has been an important and intrinsic part of contemporary Colombian history. Focusing on understudied literary and non-literary texts written by Colombian women, it traces the particularities of Colombian feminism, showing how it has been closely entwined with left-wing politics and the country’s history of violence. This book therefore rethinks the place of feminism in Latin American history and its relationship to feminisms elsewhere, challenging many of the predominant critical paradigms used to understand Latin American literature and culture.
Focusing on how to provide clean water for all - one of the key Millennium Development Goals, this book integrates technical and social perspectives. A broad, international range of case studies are provided, from developed, middle income and developing countries, in Europe, Asia, Africa, and the Americas.
