Have you ever had to provide accurate costs for a new supermarket or a pub "just an idea...a ballpark figure..." ? The earlier a pricing decision has to be made, the more difficult it is to estimate the cost and the more likely the design and the specs are to change. And yet a rough-and-ready estimate is more likely to get set in stone. Spon's First Stage Estimating Handbook is the only comprehensive and reliable source of first stage estimating costs. Covering the whole spectrum of building costs and a wide range of related MandE work and landscaping work, vital cost data is presented as: costs per square metre elemental cost analyses principal rates composite rates. Compact and clear, Spon's First Stage Estimating Handbook is ideal for those key early meetings with clients. And with additional sections on whole life costing and general information, this is an essential reference for all construction professionals and clients making early judgements on the viability of new projects.
This volume comprises the proceedings of the International Workshop on Eco logical Goal Functions, held at the Schleswig-Holstein Cultural Center of Salzau, August 30 -September 4, 1996. The conference - first in a series - intended to be convened at Salzau at 1 -2 year intervals to address various aspects of theo retical and application-oriented ecology, was initiated, organized and carried out under the auspices of the Ecology Center of the Kiel University. It featured key note addresses, invited lectures, submitted papers, and posters. 32 contributions written by authors from eight countries, were selected to be presented in this book. From the very rich discussions of the workshop, some general characteristics emerged which might become important for a deeper understanding of the nature of evolving systems or, in other words, systems with a history, described by variables with a high degree of interdependence. These characteristics include the following: Speaking of 'goal functions' is a convenient 'fa on de parler', since a logical analysis of the formal structure of teleological and causal explanations shows that both are analogous with regard to the inherent structural typology and the basic mode of explanation. Teleological interpretations introduce motives or objectives of actors into the set of 'antecedens' conditions relevant for system evolution, and are consequently a subset of causal interpretations."
Mechanics plays a fundamental role in aeolian processes and other environmental studies. This proposed book systematically presents the new progress in the research of aeolian processes, especially in the research on mechanism, theoretical modelling and computational simulation of aeolian processes from the viewpoint of mechanics. Nowadays, environmental and aeolian process related problems are attracting more and more attention. We hope this proposed book will provide scientists and graduate students in aeolian research and other environmental research some mechanical methods and principles and introduce aeolian related problems of environment to mathematical and mechanical scientists.
This book discusses the practical applications of quorum sensing inhibitors for both human and plant health. Quorum sensing inhibitors that disrupt microbial biofilms can be employed to treat bacterial infections. The book describes the various bioactive molecules that can serve as quorum sensing inhibitors to combat deadly bacterial infections, in addition to several synthetic quorum sensing inhibitors. Quorum sensing is the mechanism through which bacteria develop antibiotic resistance. Intended to provide a clearer understanding of the practical applications of quorum sensing inhibitors, the book details how the problem of antibiotic resistance can be countered through the intelligent application of quorum sensing inhibitors.
The bioaccumulation of endocrine disruptors, persistent organic chemicals and other compounds of high environmental impact has become of increasing interest in most recent environmental research, risk analysis and toxicology. This volume gives an up-to-date overview and introduces the reader to the new concept of "internal effect concentration" linking bioaccumulation and biomagnification in the food chain to ecotoxicology and risk assessment.
This book reports on the first empirical validation of "AccuRate," Australia's national benchmark software tool for house energy ratings. The validation was conducted by the University of Tasmania in collaboration with Forest and Wood Products Australia, the Australian Government, the CSIRO and industry partners. The study presented here describes the results of graphical and statistical analysis of variations observed between the measured and simulated data from three different test buildings in Launceston, Tasmania. It shows that, while the AccuRate software is well suited to modeling energy flows, there are discrepancies between the simulated and measured temperatures of the test buildings. Moreover, it highlights possible connections between the discrepancies in all zones and the outside air temperature, wind speed, global and diffuse solar radiation, and possibly the ground model. Beyond its contribution to further investigations into the ongoing improvement and calibration of the Australian NatHERS-supported AccuRate software, this book also meticulously describes the methodology used in conducting the research, which is expected to pave the way for further studies of this type.

"Modeling the Dynamics and Consequences of Land System Change" introduces an innovative three-tier architecture approach for modeling the dynamics and consequences of land system change. It also describes the principle, modules and the applications of the three-tier architecture model in detail. The approach holds strong potential for accurate predictions of the land use structure at the regional level, simulating the land use pattern at pixel level and evaluating the consequences of land system change. The simulation results can be used for the planning of land use, urban development, regional development, environmental protection, and also serve as valuable information for decision making concerning land management and optimal utilization of land resources. The book is intended for the researchers and professionals in land use or land systems, regional environmental change, ecological conservation, as well as the land resource administrative agencies and environmental protection agencies. Professor Xiangzheng Deng is a senior research fellow at the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, China.
The last two decades have witnessed an ever growing partisan divide in US politics over climate change and global warming. Significant elements in the Republican Party became openly hostile to the scientific evidence and, following the election of George W. Bush, legislative action at the federal level effectively ground to a halt. This opened up space at the state and local level to develop climate change policies with cities such as Chicago, San Francisco and New York implementing a number of initiatives that brought real and substantive developments. The election of Barack Obama in 2008 seemed to open new possibilities for federal and global leadership once more and whilst the Obama administration has been criticised for a somewhat contradictory approach to the issue at times, there were nonetheless a number of substantive policy developments. Through a substantive and detailed analysis of the politics of climate change, this book places the evolution of US climate policy within broader debates on the nature of politics in the US and argues that there exists a latent potential, often obscured by the complexities of its political system, for America to act as a world leader on the issue. This work will appeal particularly to students and scholars in American Politics, but will also prove useful to those in the fields of general Politics, climate change, sustainability, and environmental studies.
Sliding Mode Control of Switching Power Converters: Techniques and Implementation is perhaps the first in-depth account of how sliding mode controllers can be practically engineered to optimize control of power converters. A complete understanding of this process is timely and necessary, as the electronics industry moves toward the use of renewable energy sources and widely varying loads that can be adequately supported only by power converters using nonlinear controllers. Of the various advanced control methods used to handle the complex requirements of power conversion systems, sliding mode control (SMC) has been most widely investigated and proved to be a more feasible alternative than fuzzy and adaptive control for existing and future power converters. Bridging the gap between power electronics and control theory, this book employs a top-down instructional approach to discuss traditional and modern SMC techniques. Covering everything from equations to analog implantation, it: Provides a comprehensive general overview of SMC principles and methods Offers advanced readers a systematic exposition of the mathematical machineries and design principles relevant to construction of SMC, then introduces newer approaches Demonstrates the practical implementation and supporting design rules of SMC, based on analog circuits Promotes an appreciation of general nonlinear control by presenting it from a practical perspective and using familiar engineering terminology With specialized coverage of modeling and implementation that is useful to students and professionals in electrical and electronic engineering, this book clarifies SMC principles and their application to power converters. Making the material equally accessible to all readers, whether their background is in analog circuit design, power electronics, or control engineering, the authors-experienced researchers in their own right-elegantly and practically relate theory, application, and mathematical concepts and models to corresponding industrial targets.
Transdisciplinarity is a new way of scientifically meeting the challenges of sustainability. Indeed, interdisciplinary collaboration and co-operation with non-academic 'practice partners' is at the core of this; creating contextualised, socially relevant knowledge about complex real-world problems. Transdisciplinary Research and Sustainability breaks new ground by presenting transdisciplinary research in practice, drawing on recent advances by the vibrant transdisciplinary research communities in the German-speaking world. It describes methodological innovations developed to address wide-ranging contemporary issues including climate change adaptation, energy policy, sustainable agriculture and soil conservation. Furthermore, the authors reflect on the challenges involved in integrating non-academic actors in scientific research, on the tensions that arise in the encounter of theory and praxis, and on the inherently normative, political nature of sustainability research. Highlighting the need for academic institutions to be transformed to reflect transdisciplinarity, this timely volume will appeal to postgraduate students and postdoctoral researchers interested in fields such as Sustainability Science, Transdisciplinary Studies and Philosophy of Science.
The public's attitude toward air pollution in the United States evolved substantially during the 1960s. One of the results of the nation's emerging environmental ethic was the creation of the U. S. Environmental Protection Agency (EPA) in December of 1970. Prior to this time, research was focused on the impacts of air pollution on human health and welfare and was largely conducted by several federal research agencies, which included the Department of Health, Education, and Welfare; the National Oceanic and Atmospheric Administration; and the U. S. Department of Agricul ture. After the creation of the EPA, much of this work was consolidated in one regulatory agency, which resulted in periodic evaluations of the various effects of atmospheric pollution on human health, materials, agriculture, and forest ecosystems. At the same time that environmental interest was growing in the United States, concern increased in the European scientific community and public over the ecological impacts of acidic deposition. As the magnitude of the damage to European lakes and streams and the widespread decline in Norway spruce and silver fir was reported, concern that similar problems were occurring in the United States increased substantially. This concern was heightened by press reports of high elevation spruce-fir forest declines in the Adirondack and Appalachian Mountains and the decline and death of sugar maples in the northeastern United States and Canada.
International concern in scientific, industrial, and governmental communities of xenobiotics in foods and in both abiotic and biotic environments over traces has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamina tion and toxicology. This series is reserved exclusively for the diversified litera ture on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tre mendous efforts worldwide have been mobilized to evaluate the nature, pres ence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest impor tant world literature produced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest infor mation is made available to them, all with minimal literature searching."
This book analyses the drivers of specific common pool resource problems, particularly in fisheries and forestry, examining the way in which private and public regulation have intervened to fight the common pool resource problem by contributing to the establishment and maintenance of property rights. It focuses on the various forms of regulation that have been put in place to protect fisheries and forestry over the past decades - both from a theoretical as well as from a policy perspective - comparing the concrete interaction of legal and policy instruments in eight separate jurisdictions.
The objective of this hugely important text is to contribute to the existing knowledge on soil pollution and remediation. Stress is given to the critical assessment of the used analyses and methods for study effects in combined chemical pollution (organic pollutants and pesticides, metals) on soil biota and fertility. Also featured is, among other things, an evaluation of specific aspects of risk assessment, and an assessment of advanced technologies for soil remediation.
Human impact on natural landscapes through urbanization and agricultural expansion are becoming more and more dramatic and are the cause of serious environmental problems. This volume examines the effect of landscape disturbance on plant and animal diversity in the five mediterranean-climate regions of the world. It begins with three introductory chapters broadly reviewing the issues of landscape degradation. Further contributions describe regional land use conflicts in each of the five regions. Landscape disturbance and plant diversity, and landscape disturbance and animal diversity are treated in separate chapters. Four contributions deal with demography and ecophysiology in vegetation succession following disturbance. The volume closes with a consideration of the future addressing aspects of environmental politics.
This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent."
The aim of the book is to present for non-specialist researchers as well as for experts a comprehensive overview of the background, key ideas, basic methods, implementation details and a selection of solutions offered by a novel technology for the optimisation of the location of dangerous offshore activities in terms of environmental criteria, as developed in the course of the BalticWay project. The book consists of two parts. The first part introduces the basic principles of ocean modeling and depicts the long way from the generic principles to the practical modeling of oil spills and of the propagation of other adverse impacts. The second part focuses on the techniques for solving the inverse problem of the quantification of offshore areas with respect to their potential to serve as a source of environmental danger to vulnerable regions (such as spawning, nursing or also tourist areas). The chapters are written in a tutorial style; they are mostly self-contained and understandable for non-specialist researchers and students. They are carefully peer-reviewed by international experts. The goal was to produce a book that highlights all key steps, methods, models and data sets it is necessary to combine in order to produce a practically usable technology and/or decision support system for a particular sea region. Thus the book is useful not only as a description and a manual of this particular technology but also as a roadmap highlighting the complicated technical issues of ocean modeling for practical purposes. It describes the approaches taken by the authors in an understandable way and thus is useful for educational purposes, such as a course in industrially and environmentally relevant applications of ocean modeling.

The potential application areas for polymer composites are vast. While techniques and methodologies for composites design are relatively well established, the knowledge and understanding of post-design issues lag far behind. This leads to designs and eventually composites with disappointing properties and unnecessarily high cost, thus impeding a wider industrial acceptance of polymer composites. Manufacturing of Polymer Composites completely covers pre- and post-design issues. While the book enables students to become fully comfortable with composites as a possible materials choice, it also provides sufficient knowledge about manufacturing-related issues to permit them to avoid common pitfalls and unmanufacturable designs. The book is a fully comprehensive text covering all commercially significant materials and manufacturing techniques while at the same time discussing areas of research and development that are nearing commercial reality.
Specifically written for contractors and small businesses carrying out small works, this second edition of Spon's Estimating Cost Guide to Small Groundworks, Landscaping Work and Gardening contains accurate information on thousands of rates, each broken down to labour, material overheads and profit.This is the first book to focus on this range of external work, including garden maintenance work on blocks of flats and individual houses, schools and sports fields, garden makeovers, laying patios and paths, small land drainage schemes on farmland, and small-scale local authority maintenance work. |
