This Practical Guide to Rock Tunneling fills an important void in the literature for a practical guide to the design and construction of tunnels in rock. Practical Guide to Rock Tunneling takes the reader through all the critical steps of the design and construction for rock tunnels starting from geotechnical site investigations through to construction supervision. The guide provides suggestions and recommendations for practitioners on special topics of laboratory testing, durability of rock and acceptance for unlined water conveyance tunnels, overstressing or deep and long tunnels, risk-based evaluation of excavation methods, contract strategies, and post-construction inspections. Key considerations and lessons learned from selected case projects are presented based on the author's extensive international experience of over 30 years and 1000 km of tunneling for civil, hydropower, and mining infrastructure, including some of the most recognized projects in the world to date. Instead of revisiting all theory and concepts that can be found in other sources, this book contains the hard learned lessons from the author's experience in the field of Rock Tunneling, gathered over 30 years of service.

Results and conclusions of the "IEA-SSPS High Experiment" are presented together with the thermodynamic theory of the Advanced Sodium Receiver. During the experiment, flux distributions, surface temperature distributions, efficiencies and losses, were measured and calculated in a power range of 0.8-3.5 MW at different sodium inlet/outlet temperatures. The design heat flux of 1.4 MW/m2 was increased to 2.5 MW/m2 resulting in a slightly increased total receiver efficiency of over 90%.

Microbes are the predominant form of life on the planet due to their broad range of adaptation and versatile nutritional behavior. The ability of some microbes to inhabit hostile environment incompatible with most forms of life means that their habitat defines the extent of the biosphere and delineates the barrier between the biosphere and geosphere. The direct and indirect role of microbes that include bacteria, fungi, actinomycetes, viruses, mycoplasma, and protozoans are very much important in development of modern human society for food, drugs, textiles, agriculture, and environment. Furthermore, microorganisms and their enzyme system are responsible for the degradation of various organic matters. Microbes for Sustainable Development and Bioremediation emphasizes the role of microbes for sustainable development of ecosystem. Environmental microbiology role in biogeochemical cycle and bioremediation of environmental waste is major theme, which comprises the following aspects: Bacterial phytoextraction mechanism of heavy metals by native hyperaccumulator plants from complex waste-contaminated site for eco-restoration Role of microbial enzyme for eco-friendly recycling of industrial waste Field-scale remediation of crude oil-contaminated desert soil and treatment technology Microbial technology for metal recovery from e-waste printed circuit board Impact of genomic data on sustainability of ecosystem Methane monooxygenases: their regulations and applications Role of microbes in environmental sustainability and food preservation This book will be directly beneficial to researchers and classroom students, in areas of biotechnology, environmental microbiology, molecular biology, and environmental engineering with specialized collection of cutting-edge knowledge.

The energy crisis in 1973 and 1979 initiated a great number of activities and programs for low and high temperature applica tion of solar energy. Synthetic fuels and chemicals produced by solar energy is one of them, where temperatures in the range of 600-1000 DegreesC or even higher are needed. In principle such high temperatures can be produced in solar towers. For electricity production, the feasibility and operation of solar tower plants has been examined during the SSPS - project (Small Solar Power System) in Almeria, Spain. The objective of Solar Thermal Energy Utilization is to extend the experience from the former SSPS - program in to the field of solar produced synthetic fuels. New materials and technolo gies have to be developed in order to research this goal. Metallic components now in use for solar receivers need to be improved with respect to transient operation or possibly replaced by ceramics. High temperature processes, like steam-methane reforming, coal conversion and hydrogen produc tion need to be developed or at least adapted for the unconven tional solar operation. Therefore Solar Thermal Energy Utiliza tion is a long term program, which needs time for its develop ment much more time than the intervals expected in between further energy crisis. The "Studies on Technology and Applica tion on Solar Energy Utilization" is a necessary step in the right direction in order to prepare for the energy problems in the future.

The particular behavior of trace metals in the environment is determined by their specific physico-chemical form rather than by their total concentration. The introduction of atomic absorption spectrometry has lead to a plethora of scientific papers and reports in which metal concentrations in the environment are only reported as total concentrations. Only recently has the need for improved knowledge on the various forms and bioavailability of metals been realised. Considerable research effort is now devoted to measuring the concentrations of trace metals in surface waters. Efforts are made to couple chemical analytical techniques to process-related biological problems. The proceedings of the workshop on "The Speciation of Metals in " "Water, Sediment and Soil Systems" held in Sunne, Sweden, comprise these efforts and show aspects for further cooperation between analytical chemists and biologists.

Nuclear power issues have long been controversial, and often discussed from an inadequate or mistaken understanding. This book is a factual description of the whole fuel cycle, with individual chapters on specific topics from uranium mining, through the manufacture and use of fuel, to recycled products, waste disposal and progress towards a cleared site. Basic principles, environmental radioactivity (both natural and artificial) and provisions for safety are also covered. The level is pitched at a general scientific readership not necessarily familiar with the concepts, and although the viewpoint is naturally pro-nuclear, the aim is to inform rather than persuade. Where options are disputed, as whether used fuel should br reprocessed or discarded directly, both are described. The account is mainly of current practices, with the reasons for them. A final chapter suggests possible changes in the near or more distant future.

Discusses the global evolution of the earth, such as core- mantle separation, mantle-crust evolution, origin of ocean- atmosphere system, on the basis of isotope earth science and paleomagnetism, where recent devlopment in planetology and astrophysical theories are extensively taken into account.

There is currently no clear strategy for dealing with large-scale contamination projects without causing obstacles to dealing with small-scale ones (brownfields). Following the Love Canal incident, CERCLA, the Comprehensive Environmental Response, Compensation, and Liability Act (or Superfund) was legislated, and the Environmental Protection Agency (EPA) was authorized to clean up contamination from past disposal practices that pose risks to human health or the environment. It is estimated that at least 200,000-500,000 sites (brownfields) in the United States contain polluted soil or groundwater that may require remediation to overcome the negative effects of past industrial operations. The book aims to evaluate the program's ability to cope with the uncertainties at large contaminated sites while still being able to achieve flexibility for the redevelopment of comparatively smaller parcels.

Ten years ago the author, together with eight co-authors, edited a textbook Remote Sensing for Environmental Sciences within the series on Ecological Studies of Springer-Verlag. At that time there were not yet many books available on remote sensing. The decade that has elapsed was marked by a spectacular development in this field. This development took place in many directions: by widening the areas of application, by improvements of the methods and the sensors, by the introduction of new versatile platforms, but also by deepening the knowledge of the theoretical foundations. This evolution improved the ability to explain the interaction between electromagnetic radia tion and natural objects, which, in its turn, allowed for better modelization and for the creation of refined mathematical tools in the processing of remotely sensed data and in the determination of the physical status of remote objects. The community of research workers engaged in development and use of remote sensing methods changed accordingly from a modest group of scientists in the early 1970's to a considerable branch of specialized and interdisciplinary activity. The training of students had to be adapted to cope with the increasing number of people entering this new field and with the increasing quality of the material to be presented."

The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication.

The book guides specialists and non-specialists from around the world on how or whether anaerobic processes can be part of solutions for the management of municipal and industrial solid, semi-solid, and liquid residues. The simple self-learning presentation style is designed to encourage deep understanding of the process principles, plant types and system configurations, performance capabilities, operational and maintenance requirements, post-treatment needs, and management options for coproducts without complex biochemical terminologies and equations. It describes key aerobic biological treatment processes used in conjunction with anaerobic biological treatment in feedstock pre-treatment and in post-treatment of by-products. Practical pre-treatment processes, techniques and operations are described alongside additional treatment techniques of biogas, digestates and treated effluents for various end use options. Effective applications in developing countries are also considered, enabling practitioners and plant operators to effectively apply technology in temperate and warm climatic conditions.

This book states the harsh truth: that despite best intentions, our current environmental practices are doing more harm than good, and that the solution lies in creating supply chains of the future that design, produce, consume, and reuse materials in a manner that is balanced economically and environmentally. One billion beverage containers are used on a daily basis in the United States, with at least 600 million of them ending up in landfills. Even the 400 million that are recycled-at a great cost-are not accomplishing the task of helping the environment. This economic and environmental catastrophe cannot be solved by recycling programs. From his experience as a leader in the American consumer beverage industry and a researcher in Sweden, author Jack Buffington has developed a transformational solution that seeks to not just mitigate the environmental damage but jumpstart the economy while actually achieving zero waste. The Recycling Myth tells the story of how our current environmental practices are unintentionally doing more harm than good and how we need to create a radically different supply chain of the future that must, as best as possible, copy the natural system of growth, decay, and regrowth, and discontinue a disastrous pattern of material design and use. Backed by irrefutable evidence, the book destroys our comfortable notions of the recycling status quo; explains why recycling will never work in the United States, despite decades of attempts; and introduces a new system that will actually work-without asking consumers to consume less. Supplies an informed perspective from a leader in the consumer beverage industry at one of the world's largest producers of packaged beverages and a researcher in Sweden in the fields of environmental science and supply chain logistics Presents a bold counterargument to the idea that recycling and sustainability programs are inherently beneficial and introduces a new system that will benefit both our environment and economy-without asking consumers to consume less Explains why recycling and sustainability programs are ineffective because they focus solely on doing less harm rather than improving both the economy and the environment

During 1978-1982 the International Institute for Applied Systems Analysis (IIASA) was responsible for a research project on Environmental Quality Control and Management. The project was begun under the direction of Professor O. F. Vasiliev (from the Institute of Hydrodynamics of the Siberian Branch of the USSR Academy of Sciences) and was subsequently led by myself. This review is very much a re'fiection of that IIASA project. The major themes of the IIASA project were: (i) research into the methodological aspects of modeling river and lake sys tems [some of the principal results of this research appear in M. B. Beck and G. van Straten (eds. ) (1983), Uncertainty and Forecasting of Water Quality (Springer, Berlin (West)), and in K. Fedra (1983), Environmental Modeling Under Uncertainty: Monte Carlo Simulation (IIASA Research Report RR-83-28)]; (ii) case studies in the application of mathematical models to lake eutrophi cation control [results of which are summarized in L. Somlyody, S. Hero dek, and J. Fischer (eds. ) (1983), Eutrophication of Shallow Lakes: Model ing and Management (The Lake Balaton Case Study) (IIASA Collaborative Proceedings CP-83-S3), and in K. Fedra (1983), A Modular Approach to Comprehensive System Simulation: A Case Study of Lakes and Watersheds (in W. K. Lauenroth, G. V. Skogerboe, and M. Flug (eds. ), Analysis of Ecological Systems: State-of-the-Art in Ecological Modelling, pp. 195-204. Elsevier, Amsterdam)]; iv (iii) a policy study of operational water qua,lity management [M. B. Beck (1981), Operational Water Quality Management: Beyond Planning and Design (IIASA Executive Report ER-7)].

Transportation Tunnels, 2nd Edition provides a comprehensive text on tunneling and tunnel engineering applicable in general to all types of tunnels, with more detailed information on highway and railway tunnels. While the First Edition of the book was confined to deal with railway and highway tunnels, the Second Edition is also extensively considering the latest trends in use of tunnels in different other fields. The book has been revised to provide coverage of water conveyance, navigation and material conveyance tunnels also and deals with these subjects in more detail. It covers all aspects of investigation, design, construction, monitoring and maintenance of tunnels. Special emphasis has been laid on the geotechnical investigations, interpretation of findings and relating the same to the design as well as the construction of tunnels. The book reflects the advancements in the knowledge of ground behaviour and rock mechanics and also in construction technology, including use of TBM in the last two decades. It covers in sufficient detail the basic requirements of tunnel profile, the geometric parameters, clearance requirements, aerodynamics, and cost economics in fixing alignments with different design parameters like curvature, gradient and operational requirements. It discusses in detail alternative forms of the cross section / profile and illustrates design methodology with examples. The different methodologies that have been used in the past using timber or steel supports by stage wise expansion of cross sections and modern methodologies used for boring full profile using new tunneling methods and Tunnel Boring Machines are also comprehensively discussed. Requirements of tunnels in respect of ventilation, lighting and drainage are adequately covered. Separate chapters have been included on 'Instrumentation' and 'Tunnel Inspection and Maintenance'. The expanded text on the use and advantages of methodologies and equipment for dealing with various aspects of construction of tunnels is based on observations through site visits, discussions with, and experiences of people as recorded on large number of tunneling works which have been taken up recently for railways, highways and urban transport subway projects. The book can serve as a textbook for undergraduate and graduate students and as a reference book for practicing engineers.

Constructed Wetlands (CWs) are among the few natural treatment systems that can guarantee an efficient wastewater treatment and an appealing green space at the same time. However, they require large areas for their construction, which is not available in many cases. In this thesis, two domestic wastewater treatment options were designed and studied with the purpose of having a low space requirement: the Duplex-CW and the Constructed Wetoof (CWR). The Duplex-CW is a hybrid CW composed of a vertical flow CW on top of a horizontal flow filter. The stacked arrangement is the key for reducing the CW footprint. The CWR is a shallow HF CW placed on the roof of a building, thus it does not occupy any land. Several modifications and improvements have been tested, in addition to the study of the treatment performance, in order to select the most appropriate Duplex-CW and CWR design. Overall, this thesis contributes to the development of two efficient domestic wastewater treatment technologies. The Duplex-CW area requirement is still higher than many CWs and therefore further improvements are necessary. The CWR is the foremost option to save land areas since it requires 0 m2 of land per person equivalent.

The enormous public interest of specialists as well as of engaged and concerned citizens in the energy problem can be understood in view of the fact that the future of national and world-wide economy depends on the availability of sufficient primary energy. The questions arising are: which forms of primary energy exist principally? by what means and at what cost can they be brought to useful application? and what is their possible role in the present and future energy scenario? Another reason which may not be so obvious, but which eventually may prove to be of great importance as far as public acceptance of energy technologies is con cerned, lies in the fact that the existing conscious or subconscious fears arising from confrontation with scientific and technological progress - to which even for the educated layman intellectual access is diffi cult - have been sublimated onto the energy problem and especially onto the problem of nuclear energy. Un like other developments, the emergence of nuclear ener gy has brought to our notice the ambivalence of ad vancing science and technology, which may either be used peacefully or misused militarily. Nuclear energy can help to overcome the increasing hunger for energy in the world, but it can also lead to the extinction of human life from the surface of this plant. More and more, mankind is confronted with chances and risks of new discoveries.

As society becomes stressed by economic and population pressures, in turn, nature's renewable resources become stressed by harvesting pressures. For our own survival and euphoria, it is paramount that such resources remain as their name implies and not be driven to extinction through short term programs of over exploitation. Consideration of the harvesting of renewable resources leads to a simple question that was the theme of the workshop and is the focus of these proceedings: SUPPoRe you are assigned the role of manager for a specific renewable resource eco system. How would you decide on harvesting policies so that the system can be exploited economically yet at the same time maintain the integrity of the system? This, of course, is a loaded question. First of all, it is not clear that there is ever anyone single decision maker who is able to set the rules for all of the harvesters in an exploited ecosystem. The political process is complicated and to some extent unpredictable. This aspect of the question is recognized to be important, but could not be addressed here. Assuming then that someone really is in charge, what would be involved in the * decision making process? As Clark points out, "there is no alternative but first to model the system. " We agree. However, if the original question was loaded, modeling is the adulterate."

A major problem confronting the United States in the 21st century is the 20th centurys legacy of toxic waste. The weapons that fought the Cold War, the facilities that manufactured those weapons, and the factories that fueled a prosperous economy left behind a trail of pollution. Seven previously unpublished essays examine the problem of toxic waste in the United States, what is being done about it, and what should be done about it. W. Henry Lambright and Agnes Gereben Schaefer, Dianne Rahm, Sevim Ahmedov, Charles Davis, Robert A. Simons and Kimberly Winson, Santa Falcone, and Toddi A. Steelman and JoAnn Carmin write about such issues as community based environmental management, regional EPA offices and the regulation of hazardous wastes, "brownfields, " nuclear and chemical weapons destruction, environmental contamination and the nuclear weapons complex, the privatization of nuclear waste clean-up, and WIPP, Yucca, and hazardous waste transport. The future of humanity demands careful thought about these matters.

Zsuzsa Gille combines social history, cultural analysis, and environmental sociology to advance a long overdue social theory of waste in this study of waste management, Hungarian state socialism, and post Cold War capitalism. From 1948 to the end of the Soviet period, Hungary developed a cult of waste that valued reuse and recycling. With privatization the old environmentally beneficial, though not flawless, waste regime was eliminated, and dumping and waste incineration were again promoted. Gille s analysis focuses on the struggle between a Budapest-based chemical company and the small rural village that became its toxic dump site."
