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.

Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book One Welfare in Practice written by Tanya Stephens and published by CRC Press. This book was released on 2021-10-25 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal welfare has long been recognised as central to the role of the veterinary professional, but this is increasingly aligned with the welfare of humans and the broader environment in which we co-exist. This is the first book dedicated to the role of the veterinarian in One Welfare, a concept that recognises the interconnections between animal welfare, human wellbeing, and the environment. The book demonstrates, through a wide range of international case studies, why professional ethics and the use of good evidence is integral to this role. Contributors bring a rich variety of writings, each with their own perception of the role of the veterinarian in improving animal welfare and human wellbeing. One Welfare in Practice: The Role of the Veterinarian emphasises the importance of interdisciplinary collaboration and solutions: it is essential that veterinary practitioners recognise when other professionals or disciplines need to be consulted to benefit both animals and humans. With its multiple, fascinating approaches to One Welfare, this book will inform and inspire the veterinarian to find areas where collaborative action reaps the greatest rewards. This unique book shows how veterinarians can and are contributing to improving animal and human welfare, offering practical advice as to how the profession can further engage in One Welfare in a range of settings.

Download or read book Innovative Wastewater Treatment Resource Recovery Technologies Impacts on Energy Economy and Environment written by Juan M. Lema and published by IWA Publishing. This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

Download or read book The Extent of Poverty in Latin America written by Oscar Altimir and published by . This book was released on 1982 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work originated in a research project for the measurement and analysis of income distribution in the Latin American countries, undertaken jointly by the Economic Commission for Latin America and the World Bank. The present paper presents estimates of the extent of absolute poverty for ten Latin American countries and for the region as a whole in the 1970s, on the basis of available household surveys and population censuses. They are based on country-specific poverty lines representing minimum acceptable levels of private consumption, drawn according to a food-based method. Such poverty lines - ranging from 150 to 250 dollars of annual household consumption per capita - express a normative definition of the absolute dimensions of poverty, partly based on expert appraisals and partly reflecting the actual behavior of low income households facing the life style projected by Latin American development. According to these estimates, 40 percent of Latin American households were poor at the beginning of the 1970s, the incidence of poverty being 26 percent in urban areas and 60 percent in rural areas. Urban poverty extended to more than one-third of urban households in some countries (Brazil, Colombia, Honduras) while affecting between 20 and 30 percent in others (Peru, Mexico, Venezuela), about 15 percent in Costa Rica and Chile and less than 10 percent in Argentina and Uruguay. The extent of poverty in rural areas would not be less than 20 percent in any case and would reach more than 60 percent in some countries. The corresponding poverty gaps were also estimated; in terms of total household income, they may represent manageable proportions (around 2-3 percent) in the better-off countries, but are in the 4-8 percent range in the bigger countries of the region and reach as much as 12 percent in Peru and 17 percent in Honduras.

Download or read book Food Provisioning in Complex Societies written by Levent Atici and published by University Press of Colorado. This book was released on 2023-03-15 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through creative combinations of ethnohistoric evidence, iconography, and contextual analysis of faunal remains, this work offers new insight into the mechanisms involved in food provisioning for complex societies. Contributors combine zooarchaeological and historical data from global case studies to analyze patterns in centralization and bureaucratic control, asymmetrical access and inequalities, and production-distribution-consumption dynamics of urban food provisioning and animal management. Taking a global perspective and including both prehistoric and historic case studies, the chapters in the volume reflect some of the current best practices in the zooarchaeology of complex societies. Embedding faunal evidence within a broader anthropological explanatory framework and integrating archaeological contexts, historic texts, iconography, and ethnohistorical sources, the book discerns myriad ways that animals are key contributors to, and cocreators of, complex societies in all periods and all places. Chapters cover the diverse sociopolitical and economic roles wild animals played in Bronze Age Turkey; the production and consumption of animal products in medieval Ireland; the importance of belief systems, politics, and cosmologies in Shang Dynasty animal provisioning in the Yellow River Valley; the significance of external trade routes in the kingdom of Aksum (modern Sudan); hunting and animal husbandry at El Zotz; animal economies from two Mississippian period sites; and more. Food Provisioning in Complex Societies provides an optimistic roadmap and heuristic tools to explore the diverse, resilient, and contingent processes involved in food provisioning. The book represents a novel and productive way forward for understanding the unique, yet predictably structured, provisioning systems that emerged in the context of complex societies in all parts of the world. It will be of interest to zooarchaeologists and archaeologists alike. Contributors: Joaquin Arroyo-Cabrales, Fiona Beglane, Roderick Campbell, Kathryn Grossman, Patricia Martinez-Lira, Jacqueline S.

Download or read book Petrochronology written by Matthew J. Kohn and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-11-05 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petrochronology is a rapidly emerging branch of Earth science that links time (ages or rates) with specific rock-forming processes and their physical conditions. It is founded in petrology and geochemistry, which define a petrogenetic context or delimit a specific process, to which chronometric data are then linked. This combination informs Earth’s petrogenetic processes better than petrology or geochronology alone. This volume and the accompanying short courses address three broad categories of inquiry. Conceptual approaches chapters include petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry. Methods chapters address four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS. Mineral-specific chapters explore applications to a wide range of minerals, including zircon (metamorphic, igneous, and detrital/Hadean), baddeleyite, REE minerals (monazite, allanite, xenotime and apatite), titanite, rutile, garnet, and major igneous minerals (olivine, plagioclase and pyroxenes). These applications mainly focus on metamorphic, igneous, or tectonic processes, but additionally elucidate fundamental transdisciplinary progress in addressing mechanisms of crystal growth, the chemical consequences of mineral growth kinetics, and how chemical transport and deformation affect chemically complex mineral composites. Most chapters further recommend areas of future research.
