Laplacian Growth on Branched Riemann Surfaces (Lecture Notes in Mathematics #2287)
by Björn Gustafsson Yu-Lin LinThis book studies solutions of the Polubarinova–Galin and Löwner–Kufarev equations, which describe the evolution of a viscous fluid (Hele-Shaw) blob, after the time when these solutions have lost their physical meaning due to loss of univalence of the mapping function involved. When the mapping function is no longer locally univalent interesting phase transitions take place, leading to structural changes in the data of the solution, for example new zeros and poles in the case of rational maps. This topic intersects with several areas, including mathematical physics, potential theory and complex analysis. The text will be valuable to researchers and doctoral students interested in fluid dynamics, integrable systems, and conformal field theory.

Large Camel Farming: A Care-Management Guide from Breeding to Camel Products
by Bernard Faye Gaukhar Konuspayeva Cécile MagnanThis practical guide is intended for all actors in the sector who work with large camelids, whether in breeding, technical advice or veterinary care. It successively describes the general aspects of the species, the physiological bases of reproduction, lactation and feeding, the main production processes, and health and hygiene management in camel breeding. Chapters on slaughter, important camel products and their processing complete the volume.Large camels (camels and Bactrian camels) are domestic animals that are increasingly used in Western countries, as well as in Africa and Asia, for tourism, sport, and production of milk, meat, and wool. In addition, camel husbandry systems are changing, taking a greater share of sedentary systems, specializing in breeding, and intensifying production. At the same time, many veterinarians and breeders are not familiar with the animal, its needs, physiology, diseases, and management, which is often based on practices introduced for cattle and proving ineffective.This work is a practical aid for all interested readers who want to embark on the adventure of working with large camelids in a cultural context where they are not yet a dominant element of the agricultural landscape. The numerous photographs and drawings that support the text make it a unique and entertaining read.
Large Dams: Dealing With The Social, Environmental And Political Costs (Water Resources Development and Management)
by Thayer ScudderThis book highlights the first comparative long-term analysis of the negative impacts of large dams on riverine communities and on free-flowing rivers in Africa, the Middle East and Asia. Following the Foreword by Professor Asit K. Biswas, the first section covers the 1956–1973 period, when the author believed that large dams provided an exceptional opportunity for integrated river basin development. In turn, the second section (1976–1997) reflects the author’s increasing concerns about the magnitude of the socio-economic and environmental costs of large dams, while the third (1998–2018) discusses why large dams are in fact not cost-effective in the long term.
Large Dams in Asia
by Marcus NüsserThis book explores the multi-dimensional asymmetries of scale, time, and directions in the large dam controversy with a regional focus on Asia, especially on India and China. Whereas the concept of large-scale transformation of fluvial environments into technological hydroscapes originated in the West, widespread construction of large dams started in the countries of the Global South in the period after decolonisation. Construction and operation of large dams are amongst the most prestigious but also most sensitive development issues, often accompanied by massive resistance of adversely affected people and civil society organisations. Based on the notion of a contested politicised environment, various case studies are analysed to identify the dominant narratives and imaginations that shape the large dams debate. This volume largely contains contributions related to several subprojects from within the Cluster of Excellence 'Asia and Europe in a Global Context: Shifting Asymmetries in Cultural Flows', based at Heidelberg University, with several expert contributions from external researchers.

Large Outdoor Fire Dynamics
by Keisuke HimotoLarge Outdoor Fire Dynamics provides the essential knowledge for the hazard evaluation of large outdoor fires, including wildland, WUI (wildland-urban interface), and urban fires. The spread of outdoor fires can be viewed as a successive occurrence of physical and chemical processes – solid fuel combustion, heat transfer to surrounding combustibles, and ignition of heated combustibles – which are explained herein. Engineering equations frequently used in practical hazard analyses are derived and then integrated to implement a computational code predicting fire spread among discretely distributed combustibles. This code facilitates learning the procedure of hazard evaluation for large outdoor fires. Chapters cover underlying assumptions for analyzing fire spread behavior in large outdoor fires, namely, wind conditions near the ground surface and fundamentals of heat transfer; the physical mechanism of fire spread in and between combustibles, specifically focusing on fire plumes (both reacting and non-reacting) and firebrand dispersal; and the spatial modeling of 3D objects and developing the computational framework for predicting fire spread. The book is ideal for engineers, researchers, and graduate students in fire safety as well as mechanical engineering, civil engineering, disaster management, safety engineering, and planning. Companion source codes are available online.
