International conference on terrain and geohazard challenges facing onshore oil and gas pipelines : Evaluation, routing, resign, construction, operation ; Proceedings of a three day international conference on terrain and geohazard challenges facing onshore oil and gas pipelines, organised by the Institution of Civil Engineers in association with BP Exploration and held at the Institution of Civil Engineers, London, UK, on 2 – 4 June 2004
To access global oil and gas deposits, major pipelines must traverse remote regions with extreme terrains. There are a significant number of pipeline projects, active or planned, in tropical jungles, mountains and deserts, in permafrost and in areas of wetland. Each of these natural environments is associated with a range of geohazards, which may include landslides, soil erosion, karst, river migration, and seismic or volcanic activity. At the same time, society demands increasing availability and reliability of supply, together with improved environmental standards, all making for substantial challenges.
Biodiversity and Ecophysiology of Yeasts
In the last few decades more and more yeast habitats that were not investigated earlier, spanning cold climates to tropical regions and dry deserts to rainforests, have been explored. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. The recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.
Arid Dune Ecosystems: The Nizzana Sands in the Negev Desert
Sand dune dynamics plays a key role in many arid deserts. This volume provides a synthesis of a specific sand dune ecosystem, the Nizzana site in the Negev Desert. Describing its climate and geophysical/geochemical properties of soils, geological history, flora and fauna, and past/present land-use patterns, it elucidates ecological and geomorphological processes and their interrelations, based on long-term monitoring, in situ experiments and satellite imagery. Particular attention is drawn to the impact of the topsoil biological crust in controlling water availability at local/regional scales. The interdisciplinary approach adopted in this case study offers a good example of a highly complex and dynamic system, which could easily be applied to other sandy ecosystems.
Arabian Deserts : Nature, origin and evolution
This is the first comprehensive survey of all the deserts of Arabia, based largely on the author's 50 years of experience there. The text deals with every kind of desert in the region, from vast sand seas to clay pans and stony plains to volcanic flows.
