Volume 18 in the CGL-Studies series, entitled "Environmental Policy and Landscape Architecture", is the result of an international symposium held in Jerusalem in March 2011 which was organised by the Van Leer Jerusalem Institute in collaboration with the Centre of Garden Art and Landscape Architecture. The symposium focused on how the many different facets of landscape architecture could help towards solving environmental problems. Sustainable Development and Landscaping, Environmental Policy and the Contribution of Landscape Architecture at a Local Level, Designing Public Open Spaces and Social Sustainability, Spatial Planning and Landscape Architecture in Israel/Palestine, and Water and Soil: Crisis and Conservation are the key chapters in this volume. The authors address a wide range of issues including the significance of religions in ideas about environmentalism in historical and current debates, how Palestinian society can meet challenges posed by the dynamic development of urban structures through capacity building in landscape architecture, and economically meaningful strategies for soil conservation in arable fields as part of agricultural sustainability in semi-arid areas. A key objective of the symposium was also to determine opportunities for cooperation in the field of environment and landscaping for Israelis, Palestinians, Muslims, Jews and Christians in a region marked by huge tension and conflicts. The authors are scholars of various disciplines such as landscape architecture, urban planning, technology assessment, philosophy of science, environmental communication and ecology, and come from Israel, Palestine, USA, Norway and Germany.

The flexible use of prefabricated concrete products requires a continuously increasing diversity with regard to fresh concrete mix designs and properties, moulding processes, surface finishes and product characteristics.This trend imposes ever-higher requirements on manufacturers of the associated production equipment and on precast plants. The main goal is to implement a flexible production system in all processing stages. The relevant correlations and interactions need to be thoroughly considered and evaluated in order to ensure that concrete products and precast elements are manufactured to the required quality standard.To date, no comprehensive description of these correlations has been published in the relevant literature. This richly illustrated book closes the gap by describing the basic principles of the production processes, the fundamentals of materials, the composition of the concrete mix, and the equipment used for concrete production. Clearly arranged chapters detail the production processes and equipment used to manufacture small concrete products, concrete pipes and manholes, and precast elements.The authors have used their many years of experience in the field of precast technology and their close ties to the industry. Their aim was to integrate modern testing and calculation methods from neighbouring disciplines into precast technology. This includes, for instance, modelling and simulation of the workability behaviour of mixes, implementation of the latest advancements in machine dynamics to the design and engineering of production equipment, and the use of stateof-the-art measuring and automation technology for quality control purposes.

When used as an addition and binder component, fly ash has become an indispensable construction material for many concrete applications. The conditions produced in power stations when firing fine pulverized coal result in the formation of a reactive, flour-fine, pozzolanic mineral material from the accompanying rock in the coal. Owing to its specific characteristics it has a positive impact on the properties of fresh and hardened concrete and facilitates cost-effective production of high-grade, durable concretes.The authors of this handbook have combined the latest discoveries from the field of research with practical experience of the use and effects of fly ash in concrete. This handbook provides the necessary information and makes interesting suggestions for selective use of fly ash in concrete.

Este libro ha sido escrito con objeto de proporcionar a los dibujantes técnicos en particular y a los estudiantes en general un tratado de las cuestiones más importantes de la Geometría descriptiva y sus aplicaciones en las distintas ramas de la Ingenieria.

When George I, Elector of Hanover, was crowned King of England in 1714, he established a dynastic union between the two countries that endured until 1837, leaving many cultural and political accomplishments to posterity. The 300th anniversary of this union led the Institute of Landscape Architecture, Technische Universitat Dresden, and the Centre of Garden and Landscape Architecture (CGL), Leibniz Universitat Hannover, to take a critical look at the gardens that resulted. The symposium "Hanover and England: a union of state and garden / German and British garden culture between 1714 and today" was sponsored by the Lower Saxonian Ministry of Science and Culture. The resulting papers dealt with far more than garden history, addressing as well the background and channels by which ideas on art, agriculture, commerce, technology, literature and politics were exchanged. Given the encyclopedic interests of late 18th century thinkers, it was necessary to invite several academic disciplines to participate, in order to describe and discuss the cultural transfer between Great Britain and Hanover. The transfer of horticultural and artistic ideas very often flourished in the 19th century at different places. For this reason, the conference focused on two key aspects: the Hanoverian-British exchange between 1714 and 1837 (the period of the actual royal union) and the Anglo-German relations that endure to the present day.Als Georg I., Kurfurst von Hannover, 1714 zum Konig von England gekront wurde, begrundete dies eine Personalunion zwischen den beiden Landern, die bis 1837 bestand und der Nachwelt eine Vielzahl kultureller und politischer Errungenschaften hinterlie. Das 300-jahrige Jubilaum dieses Zusammenschlusses nahmen das Institut fur Landschaftsarchitektur der Technischen Universitat Dresden und das Zentrum fur Gartenkunst und Landschaftsarchitektur (CGL) der Leibniz Universitat Hannover zum Anlass, sich kritisch mit den in dieser Zeit entstandenen Garten auseinanderzusetzen. Das Symposium "Hanover and England: a union of state and garden / German and British garden culture between 1714 and today" wurde vom Niedersachsischen Ministerium fur Wissenschaft und Kultur gefordert. Die Beitrage beschaftigten sich nicht nur mit Gartengeschichte, sondern widmeten sich auch dem Austausch von Ideen zu Kunst, Landwirtschaft, Handel, Technologie, Literatur und Politik. So schien es sinnvoll, unterschiedliche akademische Disziplinen zur Teilnahme einzuladen, um den kulturellen Transfer zwischen Grobritannien und Hannover zu untersuchen und zu diskutieren. Die Konferenz konzentrierte sich auf zwei Schlusselaspekte: den hannoverisch-britischen Austausch zwischen 1714 und 1837 (die Zeit der Personalunion) und die deutsch-englischen Beziehungen, die bis heute andauern.

Volume 27 of the CGL-Studies "Jewish Horticultural Schools and Training Centers in Germany and their Impact on Horticulture and Landscape Architecrture in Palestine / Israel" presents the results of a symposium which was held in September 2016 at the Leo Baeck Institute Jerusalem, jointly organized by the Leo Baeck Institute, the Faculty of Architecture and Town Planning of the Technion, Haifa, and the Center of Garden Art and Landscape Architecture of Leibniz University Hannover.The volume presents four main chapters. The first, "Hachsharot in Context", deals with the context and changing role of Jewish agricultural training in Germany and Hachsharot in the time of the Nazi dictatorship. In the next chapter, "Perceptions of Nature", ideas of the Jewish youth movement about nature and landscape and the perceptions of nature among Hachshara members are discussed. "Hachsharot in Germany and Palestine", the third chapter, presents papers on Jewish horticultural training centers in Germany in the regions of Hannover and Berlin/Brandenburg, as well as on Gross-Gaglow, a cooperative Jewish settlement located near Cottbus, and on Kfar Ruppin and Sde Eliyahu, a secular and a religious Kibbutz in Israel, respectively. The papers in the concluding chapter "Beyond Hachsharot", deal with the lives and work of female Jewish gardeners and garden architects in Vienna, and with the Ahlem memorial and documentation center, established at the site of the former Israelitische Gartenbauschule Ahlem (Jewish Horticultural School Ahlem) in Hannover.
