Book Description
El presente trabajo analiza el servicio de un corredor de transporte público (TP) mixto operado por tranvía y autobuses. Este tipo de configuraciones se presentan en arterias principales de ciudades con alta demanda de movilidad, donde el espacio público y la segregación del vehículo privado son aprovechadas por los vehículos de TP con distintas características físicas y cinemáticas. Se ha estimado la velocidad comercial resultante en ambos medios de transporte, con un modelo macroscópico en función de las variables de diseño y operación del servicio: separación entre paradas, intervalos de paso, demanda de usuarios. Asimismo, se han modelizado las operaciones simultáneas de una línea de autobús y una línea de tranvía en un mismo corredor urbano, para posteriormente simular trayectorias deterministas de ambos modos (con el apoyo de una hoja de cálculo) y finalmente, analizar el grado de sensibilidad de las estrategias mediante el planteamiento de distintos escenarios de operación. Para cada estrategia, la performance del sistema mixto se ha evaluado en función de los costes de operación y tiempos de viaje (costes operador y costes usuario, respectivamente). A nivel particular, se ha investigado la influencia y potencialidades de la ubicación de apartaderos o puntos de avance para la parada de autobús a lo largo del corredor, según la distancia de alcance del tranvía al autobús y las diferencias de velocidades máximas. Finalmente, se recomienda la aplicación de estrategias colaborativas entre el autobús y el tranvía con separación de paradas de bus de 350 m o más. Y, concretamente, la separación más apropiada sería la de 400 m, ya que de esta forma, las paradas de tranvía y bus serían compartidas por ambos modos en toda la extensión del corredor integrado, reduciendo aún más los costes de operación, y los tiempos de transferencia entre modos para los usuarios. Por lo tanto, queda comprobado que la velocidad comercial del autobús se ve incrementada considerablemente a medida que aumenta la distancia entre paradas.

Book Description
This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Book Description
Cities of Tomorrow is a critical history of planning in theory and practice in the twentieth century, as well as of the social and economic problems and opportunities that gave rise to it. Trenchant, perceptive, global in coverage, this book is an unrivalled account of its crucial subject. The third edition of Cities of Tomorrow is comprehensively revised to take account of abundant new literature published since its original appearance, and to view the 1990s in historical perspective. This is the definitive edition, reviewing the development of the modern planning movement over the entire span of the twentieth century.

Book Description
Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.

Book Description
Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.

Book Description
A beautiful book on the famed Chinati Foundation in Marfa, Texas The Chinati Foundation, a world-famous destination for large-scale contemporary art, was founded by Donald Judd (1928-1994) to preserve and present a select number of permanent installations that were inextricably linked to the surrounding landscape in Marfa, Texas. This handsome publication, first published in 2010 and now available with a new chapter devoted to the permanent installation by Robert Irwin that was inaugurated in 2016 and a new foreword by Jenny Moore, director of the Chinati Foundation, describes how Judd developed his ideas of the role of art and museums from the early 1960s onward, culminating in the creation of Chinati. The individual installations featured here include work by John Chamberlain, Dan Flavin, David Rabinowitch, Roni Horn, Ilya Kabakov, Richard Long, Ingólfur Arnarsson, Carl Andre, Claes Oldenburg and Coosje Van Bruggen, and John Wesley, as well as by Judd himself. The book also features a complete catalogue of the collection and writings by Judd relating to Chinati and Marfa. Published in association with the Chinati Foundation/La Fundación Chinati
