  • Methods of Treatment of Unstable Ground

    • 1 Edición
    • F G Bell
    • Inglés
    Methods of Treatment of Unstable Ground focuses on the methods of treatment that have been adopted by engineers in their attempts to make unstable ground usable. These methods are meant to stabilize ground, either temporarily as in ground-water lowering or freezing techniques, or permanently as in grouting. This book is comprised of 11 chapters. The first of which reviews some of the modern techniques in addressing problems caused by unstable ground, including those caused by water in excavations, instability of natural or excavated slopes, the settlement of structures on soft or loose soils, and subsidence due to extraction of minerals from the ground. These techniques range from ground-water lowering to the use of an impermeable barrier around the excavation to prevent inflow and at the same time maintain the surrounding water table at its normal level. Attention then turns to the use of electro-osmosis and electrochemical stabilization in ground engineering; control of groundwater by excluding it through grouting; and fundamental conditions governing the penetration of grouts. The remaining chapters explore grout selection based on engineering performance; ground conditions in mining areas; clay grouting and alluvial grouting; and ground freezing. Finally, the use of cement to stabilize soil and of vibroflotation to improve poor ground below foundations of structures is described. This book should prove useful to engineers engaged in ground engineering.

  • Ecology of the Northern Lowland Bogs and Conifer Forests

    • 1 Edición
    • James A. Larsen
    • Inglés
    Ecology of the Northern Lowland Bogs and Conifer Forests is a book on the ecology of bogs and conifer swamps and, to some extent, the marshlands. The chapters that follow are, for the most part, a review of what is known about the northern bogs and lowland forests, written in the terminology of science in the hope, as well as the expectation, that such knowledge will be of value to those who appreciate the beauty of bogs and marshlands, to ecologists and other biological scientists, naturalists, wildlife conservationists, hunters, trappers, construction engineers, as well as to others whose vocations or avocations take them afield. The discussion is devoted, at least primarily, to the ecology of one kind of wetland—the lowland bogs and conifer forests—and treats only in passing the marshlands and other kinds of vegetational communities that are also classified as wetlands. Of particular concern are the lowland peat bogs and forests, especially those that have developed to a point where their identity is indisputable for the simple reason that no other review of accumulated knowledge on these vegetational communities is presently available.

  • Basic Water and Wastewater Treatment

    Butterworths Basic Series
    • 1 Edición
    • T H Y Tebbutt
    • Inglés
    Basic Water and Wastewater Treatment discusses the water cycle, flow measurement, physical treatment processes, chemical treatment processes, biological treatment process, and sludge handling and treatment. The book also describes the use of the BASIC computer program to calculate problems involving water pollutants. Flow measurements involve the use of a gauging structure, velocity measurements of a known cross-section, or dilution gauging. To evaluate, in quantitative terms, the effects of a certain pollutant discharged and received by a body of water, the investigator can employ a tool in chemical dilution gauging—the mass balance analysis. Many microorganisms, organic and inorganic compounds degrade in a natural process of self-purification; their decay can be modeled as an exponential function. One standard of water treatment facility or wastewater treatment plant cannot be built to deal with all the various components of water pollution. The book cites relevant standards such as the EC Directive 80/778/EEC: "Quality of Water Intended for Human Consumption" in the EU; the "Safe Drinking Water Act" in the U.S.A.; and the "Guidelines for Drinking Water Quality" issued by the World Health Organization. The book describes water quality parameters, water supply sources, and wastewater collection, including its treatment and disposal.

    Lakes of New York State, Volume I: Ecology of the Finger Lakes describes the state of Finger Lakes, which is a group of eleven elongated bodies of water of glacial origin in the west-central portion of New York, and its respective watershed. This book assesses the structure of the Finger Lakes’ plant and animal communities and how these communities interact with the abiotic components of the environment. The condition of the lakes from the standpoint of fish population dynamics are also analyzed, including an examination of the various physical, chemical, and biological aspects of the lakes' ecosystem. This text ranks the Finger Lakes into a unilateral trophic list by tabulating their trophic information according to three commonly used indicator measurements— average summer Secchi disc depth, average summer chlorophyll a concentration, and average winter total phosphorus level. This publication is valuable to limnologists and ecologists working on temperate zone freshwater lakes.

    The Red Sea is a unique and fragile environment. All but landlocked between Africa and Arabia, its peculiar oceanographic conditions, its geographical position and its geological history all conspire to make it particularly vulnerable to the side-effects of human civilization. In places, it is already a key environment under threat. What makes the Red Sea unique? What are the threats to this environment? Where should future research be directed? These are just three of the major questions addressed by the scientists contributing to this book.

    • Inglés
    Of the vast area of structurally similar vegetation that forms the Far Eastern tropical rain forest block, only the forests of peninsular Malaysia lie on the mainland of Asia. Although showing some influence from this source, the flora and fauna are distinctive and exceedingly rich in species. Among other factors, this richness reflects the complex structure of the vegetation, justly famous for the extensive stands of tall trees that create the conditions to which many smaller plants, fungi and a huge variety of animals are adapted. After a century of scientific investigation, it is now possible to understand peninsular Malaysia's complex ecosystem as an essential prerequisite to the successful management for conservation and long-term productivity in the area. Compiled by authors with personal experience of the region, this book constitutes the most authoritative account of this diverse and fragile region. It is essential reading for all those interested in Malaysia and its conservation.

    Visualization in Modern Cartography explores links between the centuries-old discipline of cartography and today's revolutionary developments in scientific visualization. The book has three main goals: (1) to pass on design and symbolization expertise to the scientific visualization community - information that comes from centuries of pre-computer visualization by cartographers, and their more recent experiences with computerizing the discipline; (2) to help cartographers cope with the dramatic shift from print cartography to a dynamic virtual cartography for which their role is changing from that of map designer to one of spatial information display (and/or interface) designer; (3) to illustrate the expanded role for cartography in geographic, environmental, planning, and earth science applications that comes with the development of interactive geographic visualization tools. To achieve these goals, the book is divided into three parts. The first sets the historical, cognitive, and technological context for geographic/cartograp... visualization tool development. The second covers key technological, symbolization, and user interface issues. The third provides a detailed look at selected prototype geographic/cartograp... visualization tools and their applications.

    This new volume from the SETAC (Society of Environmental Toxicology and Chemistry) Special Publications Series examines the phenomenon of persistent pollutants in the seas and oceans. Unlike the highly visible and obvious effects caused by oil, certain chemicals have unseen but long-term and far-reaching effects on the marine ecosystem. They often have long half-lives, are carried great distances and pass easily through the food chain from prey to predator. The behaviour and effects of these persistent pollutants on each type of marine animal (invertebrates, vertebrates, fish, mammals and fish-eating birds) are described. A final overview draws the observations and conclusions together presenting a work that provides a foundation for understanding the behaviour of persistent pollutants in the marine environment.

    • Inglés
    A Review of the Radiosensitivity of the Tissues in Bone is a report prepared by the Task Group for the International Commission on Radiological Protection Committees 1 and 2. The book reviews a biological indicator of the maximum permissible radiation dose. Data shows that an induction of malignant change should be considered as the limiting factor in maximum permissible levels for the bone. The risk of carcinogenesis in cells is connected with the proliferative potential of the cells. These cells are on bone marrow surfaces, in hematopoietic marrow, and in certain epithelial cells close to bone surfaces. The text also reviews the changes in the patterns of distribution resulting from growth and remodeling of bone. The book examines the effect of distribution of alkaline earth, of plutonium, of thorium, of americium, and of phosphorus in bone growth. The book also evaluates the comparative tumorigenic effects of external and internal irradiation of bone and the factors to be considered in determining the dose limitation from bone-seeking radionuclides. This book can prove beneficial to researchers and practitioners in the fields of radiology, internal medicine, or oncology.
