This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerosas carreteras en el mundo son reparadas, se corrige su trazado o se renuevan sus capas. Ello genera una importante cantidad de mezcla asfáltica fresada, que constituye un material que tratado adecuadamente es reciclable. La valorización de materiales reciclados en la construcción es beneficiosa tanto para el medio ambiente como para la economía. Diferentes departamentos de transporte estatales de EE. UU., así como varias administraciones europeas permiten el uso de áridos reciclados asfálticos como materiales para las capas de firme en distintos porcentajes mezclado con áridos naturales. Con el objetivo de valorizar los áridos reciclados producidos en las obras de carreteras, este estudio evalúa la mezcla de áridos reciclados asfálticos y áridos reciclados de hormigón de baja calidad estabilizados con cemento, para ser utilizada como material granular en las capas de firmes de carretera. Así mismo se evalúa la capacidad portante de dichas mezclas sin ligante también con el propósito de utilizarlas en capas de firmes. De estos tipos de mezcla existen pocos datos. El estudio de suelo-cemento se llevó a cabo en muestras de 100% áridos reciclados de hormigón y con mezclas de áridos reciclados de hormigón y áridos reciclados asfálticos, las cuales contienen 10%, 25% y 50% áridos reciclados asfálticos. Las muestras fueron ensayadas en el laboratorio para caracterizar el material y clasificar el uso del mismo como material granular estabilizado con cemento, según establece el artículo 513 del PG-3 vigente, también se realizaron ensayos de laboratorio para determinar las propiedades mecánicas: proctor modificado, resistencia a la compresión, módulo de elasticidad y capacidad de soporte CBR. Los resultados obtenidos en las diferentes muestras cumplen las exigencias de la norma española para un material granular tratado con cemento SC40 y también sin cemento. Debido a que el estudio fue realizado con un árido de baja calidad, intentado tener unas condiciones adversas, el por ciento de cemento requerido para alcanzar la resistencia exigida es un tanto superior al por ciento comúnmente utilizado en los suelocemento, pero aún por debajo del máximo recomendado. Algo interesante en el estudio es que a medida que aumenta la incorporación de árido reciclado asfáltico aumenta la resistencia a compresión y disminuye la capacidad soporte CBR, a pesar de esto el menor valor de CBR obtenido en la muestra que contiene el 50% de árido reciclado asfáltico es considerado bueno y está por encima del mínimo exigido por el PG-3. Por último, con los resultados obtenidos en las diferentes muestras se realizó un ejercicio de dimensionamiento de firme utilizando el método AASHTO-1993, los resultados fueron comparados con los exigidos por la norma española de secciones de firme, los cuales cumplen con los mínimos espesores exigidos para la sección analizada.

Book excerpt: From the author of The Campaign and No Rules of Engagement… Pamela Wright will never forgive her sister for dying in the Afghanistan war, or the Army for Laura’s death, or anyone else for making it okay for Laura to go halfway around the world to fight for reasons Pam has never fathomed. Numb with grief, she buries her sister but not her rage. Among the mourners is Trish Tomlinson, who loved Laura long ago and has found the news of Laura’s death sharply painful. She remembers Pam as an unwelcome third wheel, but now finds comfort in the company of the young medical resident, and in the details of Laura’s journal that Pam shares. Brought together by grief, something more grows. Guilt and anger cloud their feelings and jeopardize any chance at a future. How can love blossom in the shadow of death?

Available in PDF, EPUB and Kindle. Book excerpt: This book is number two in a series for Primates in Fragments. In this volume, ten years after the first http://www.springer.com/social+sciences/anthropology+%26+archaeology/book/978-0-306-47696-9, we continue to address issues regarding primates within a fractured landscape. There are seven sections based on specific categories of primates in fragments. In the Introductory section, authors discuss the issues surrounding primates in remnant habitats as well as encourage discussion about what we mean by fragmentation on a landscape scale. In the Long-Term and Regional Studies section, authors present information on changes that have occurred during longer studies as well as changes that have occurred over regions. In the Landscape, Metapopulations and the Matrix section, authors cover topics from dry to moist forests, and from metapopulations to single species use of multiple fragments locations. In Feeding and Behavioral Ecology, authors take a closer look at the flexibility and responsiveness of primates in fragments in terms of their food choices, resource use, and behavioral changes. In Endemic, Endangered, and Nocturnal Primates authors uncover details involving critical primates living in major city centers to the heights of the Himalayas. In Genetics, Disease and Parasites authors cover topics including population viability, disease and parasite transmission between primates in fragments and humans. Finally, in the Conservation and Ecology: Threats and Management section, we synthesize information in this volume and make recommendations for the future of work in this field and the survivability of primates in fragments.
