  • Wetlands of Bottomland Hardwood Forests

    • 1st Edition
    • Volume 11
    • J.R. Clark + 1 more
    • English
    These Proceedings comprise two parts. Part I contains eight contributed papers on hydrology, fauna, soils, forests, agriculture and ecology. Part II comprises reports resulting from the five interdisciplinary workgroups whose participants included ecologists, botanists, zoologists, engineers, hydrologists, agrologists, dendrologists, resource managers and other specialists. Their aim was to evaluate conservation and management practices for wetland portions of the bottomland forests of the southeastern United States and to provide technical advice to responsible federal agencies. Thus the book is a state-of-knowledge review of scientific literature and current research, particularly that necessary to understand the effects of alterations such as forest clearing, land drainage or levee building that impair natural functions, i.e. production of timber, maintenance of water quality, flood water storage, support of migrating waterfowl and fish, carbon dioxide balance of the atmosphere etc.

  • Controlled Atmosphere and Fumigation in Grain Storages

    The symposium was organised by Co-operative Bulk Handling Limited and the Australian Grain Institute Incorporated in collaboration with the Commonwealth Scientific and Industrial Research Organisation and Food and Agricultural Organisation of the United Nations. The meeting attracted 270 participants from 28 countries, and as it was devoted to the practical aspects of the subject, it included a field trip to sites in various stages of the sealing exercise in order to provide coverage of the broad aspects of grain handling, storage, transport and quality control. These proceedings contain the 49 papers presented, together with a description of the field visits, plus records and discussions.

  • Platinum-Group Element Exploration

    • 1st Edition
    • Volume 26
    • D.L. Buchanan
    • English
    The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium and osmium. They are currently receiving world-wide attention as an attractive exploration target because they offer the dual attraction of rare, high value precious metals as well as major industrial applications. Platinum has aesthetic qualities, combined with a permanent lustre, which encourage its use in the manufacture of jewellery and, like gold, it also finds an investment role. Platinum, rhodium and palladium have important applications as catalysts, enabling petroleum and other fuels and chemicals to be produced efficiently from crude oil. This book gives a practical set of guidelines for implementing a programme of PGE exploration, detecting subtle indications of mineralization and assessing the economic potential of a group of mafic or ultramafic rocks. Background material is given on the economic and geological framework of the PGE in the first chapter, while theoretical aspects of magma chemistry are covered in the next three. Chapters 5 and 6 review current world-wide exploration activity within the context of available reserves of PGE, and in Chapter 7 factors which need to be considered in exploration for new deposits are outlined. The last chapter discusses evaluation guidelines.As the PGE are both costly and almost indestructible they are normally recycled; nevertheless, a substantial annual input of new metal is needed to replace process losses, to permit increases in capacity in the dependent industries and to provide for new uses. For example, a major new market for platinum will be created if the European Community countries are required to fit catalytic converters to new cars. At present, South Africa and the USSR are the sources of most of the western world's newly mined PGE, with virtually all the South African production derived from the Bushveld Complex. Much of the material presented in this book is based on the author's experience of these rocks, and emphasis is given to the dominant role played by magmatic sulphides as potent collectors of PGE. Consumers of minerals and metals, however, prefer to have a diversity of supply and a new PGE producer is therefore likely to attract a ready market.Not only does the book provide a wealth of practical information for mining geologists, it also contains much of interest to those in natural resource management and investment.

    ANABIOTEC '92 focused on the further integration of biotechnology and analytical chemistry. The results of this symposium clearly demonstrated that a substantial progress could be reported in the application of both conventional and new analytical techniques, the latter essentially based on natural analytical tools such as biomolecules. The main themes covered during this meeting are fermentation monitoring, chromatography, instrumental analysis, biosensors and bioanalysis.

  • Regional and Specific Deposits

    • 1st Edition
    • Volume 9
    • Bozzano G Luisa
    • English
    Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 9: Regional and Specific Deposits focuses on the processes, methodologies, principles, and approaches involved in the identification of regional and specific ore deposits. The selection first elaborates on the timing of mineralization in stratiform copper deposits, oolitic iron formations, and metalliferous deep-sea sediments. Discussions focus on marine distribution and nature of surface and near-surface deposits, structural setting and associated deposits, principal types of deep-sea metal-enriched sediments, chronological development of oolitic-inland-sea iron formation, and complementary sources and transport mechanisms. The text then tackles heavy-metal accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits. Topics include lithological associations, oxidation and supergene alteration of ores, temporal and tectonic setting, dissolved metal concentrations in large freshwater systems, and transport phases of heavy metals in river water. The publication examines strata-bound tin deposits, geology of the Pine Point lead-zinc district, and genesis of the Rammelsberg ore deposit near Goslar/Upper Harz in the Federal Republic of Germany. The selection is a valuable reference for researchers wanting to explore ore deposits.

  • Shrub-Steppe

    Balance and Change in a Semi-Arid Terrestrial Ecosystem
    • 1st Edition
    • Volume 20
    • Alec Rickard + 3 more
    • English
    Owing to man-made intervention, the shrub-steppe now represents a rapidly disappearing landscape in the arid regions of North America. This book represents a systems-level study of ecological variables affecting water balance, and responses to perturbation. The study focused on a very large, protected, landscape unit, comprising a natural ``watershed'' area located in the semi-arid western United States. Long-term and concurrent data sets were established with a view towards establishing system-level responses to manipulative interventions, and natural perturbations like wildfire. These data sets were established for micrometeorology, climatology, mineral cycling in soils, nutrient and mineral pathways in springs and streams, vegetational dynamics, and population changes on the site. In synthesizing nearly twenty years of data, the more interesting ecosystem level responses concerned vegetational recovery and water balance. For instance, the synthesis uniquely demonstrates the interaction of biotic and non-biotic factors and their integrated effect on regional water balance. However, special attention was also paid to species diversity and the genetic resource pool represented at this site.This book will be of primary interest as a reference resource to land managers and wildlife specialists, and as a research study for scientists interested in systems-level ecology. Conservation-minded citizens who take more than a cursory interest in ecology will also find it interesting.

    • English
    Corrosion Guide presents a list of corrosive agents and the trade names of materials, including metallic and non-metallic materials as well as alloys. The book provides guidance in using the tabulated information. This reference also lists relevant publications that deal with the properties of various materials. This new edition provides more data that are not included in the previous edition. The former edition fails to present enough information as the provided properties of the corrosive agents varies and other data are not available. The release aims to minimize missing information about the subject matter. This compilation of tabulated data provides description of each group of corrosive agents. Elements and compounds under each group are listed, along with their properties such as room temperature, corrosion rate, and composition. The list of trade names of materials also describes the composition of each material. The information contained in this book is intended to help practicing engineers deal with corrosion.
