Download or read book Acid Toxicity and Aquatic Animals written by R. Morris and published by Cambridge University Press. This book was released on 1989-03-16 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews and presents recent research on acid waters and their effects on aquatic animals. Starting with the environment, in order to assess why the problems have arisen in particular areas, the volume then deals with field and survival studies on invertebrates and vertebrates; examines the extent of the biological problem and the attempts that have been made to relate water quality and the susceptibility of animals. The natural progression of environmental and field studies, toxicity, and survival tests provide the background information for the physiological studies that follow. These form the major component of the book and they seek to analyze the toxic effects of acid waters and trace metals with cardiovascular and endocrinological effects.

Download or read book Advances in Historical Ecology written by William L. Balée and published by Columbia University Press. This book was released on 2012-09-18 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology is an attempt to understand the reciprocal relationship between living and nonliving elements of the earth. For years, however, the discipline either neglected the human element entirely or presumed its effect on natural ecosystems to be invariably negative. Among social scientists, notably in geography and anthropology, efforts to address this human-environment interaction have been criticized as deterministic and mechanistic. Bridging the divide between social and natural sciences, the contributors to this book use a more holistic perspective to explore the relationships between humans and their environment. Exploring short- and long-term local and global change, eighteen specialists in anthropology, geography, history, ethnobiology, and related disciplines present new perspectives on historical ecology. A broad theoretical background on the material factors central to the field is presented, such as anthropogenic fire, soils, and pathogens. A series of regional applications of this knowledge base investigates landscape transformations over time in South America, the Mississippi Delta, the Great Basin, Thailand, and India. The contributors focus on traditional societies where lands are most at risk from the incursions of complex, state-level societies. This book lays the groundwork for a more meaningful understanding of humankind's interaction with its biosphere. Scholars and environmental policymakers alike will appreciate this new critical vocabulary for grasping biocultural phenomena.
Download or read book The Sunken Billions written by World Bank and published by World Bank Publications. This book was released on 2009-02-25 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The Sunken Billions: The Economic Justification for Fisheries Reform' shows the difference between the potential and actual net economic benefits from marine fisheries is about $50 billion per year, or some $2 trillion over the last three decades. If fish stocks were rebuilt, the current marine catch could be achieved with approximately half the current global fishing effort. This illustrates the massive overcapacity of the global fleet. The excess competition for the limited fish resources results in declining productivity, economic inefficiency, and depressed fisher incomes. The focus on the deteriorating biological health of world fisheries has tended to obscure their equally critical economic health. Achieving sustainable fisheries presents challenges not only of biology and ecology, but also of managing political and economic processes and replacing pernicious incentives with those that foster improved governance and responsible stewardship. Improved governance of marine fisheries could regain a substantial part of this annual economic loss and contribute to economic growth. Fisheries governance reform is a long-term process requiring political will and consensus vision, built through broad stakeholder dialogue. Reforms will require investment in good governance, including strengthening marine tenure systems and reducing illegal fishing and harmful subsidies. Realizing the potential economic benefits of fisheries means reducing fishing effort and capacity. To offset the associated social adjustment costs, successful reforms should provide for social safety nets and alternative economic opportunities for affected communities.

Download or read book Practical Food Rheology written by Ian T. Norton and published by John Wiley & Sons. This book was released on 2010-12-01 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheology is fundamentally important in food manufacturing in two major senses. Understanding the way in which a substance moves and behaves is essential in order to be able to transport and mix it during processing. Secondly, the rheology of a product dictates much of the consumer experience, e.g. in relation to texture and mouthfeel. This book doesn’t overwhelm the reader with complex mathematical equations but takes a simple and practically-focused approach, interpreting the implications of rheological data for use in different food systems. Through this approach industry-based food developers / rheologists, students, and academics are given clear, concise interpretation of rheological data which directly relates to actual perceived functionality in the food. The functionality may relate to texture, structure and mouthfeel, and may result as a function of temperature, pH, flocculation, concentration effects, and mixing. The interpretative view is based on the principle that the food rheologist will produce a graph, for example of viscosity or gelation profiling, and then have to extract a practical meaning from it. For example, if viscosity falls with time as a function of pH, this knowledge can be used to tell the customer that the viscosity can be followed with just a pH meter and a stopwatch. Rheological measurements have shown that once the pH has dropped 1 unit after 10 minutes, the viscosity has been halved. This is the type of practical and valuable information for customers of the industrial food rheologist which the book will enable readers to access. Key features: A uniquely practical approach to the often difficult science of food rheology Includes chapters introducing the basics of food rheology before moving on to how data can be usefully and easily interpreted by the food scientist Can be used as a teaching aid on academic or industry-based courses
Download or read book Anaerobic Digestion Model No 1 ADM1 written by IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes and published by IWA Publishing. This book was released on 2002-02-01 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.
