This book was released on 2006 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Formal pension systems are an important means of reducing poverty among the aged. In recent years, however, pension reform has become a pressing matter, as demographic aging, poor administration, early retirement, and unaffordable benefits have strained pension balances and overall public finances. Pension systems have become a source of macroeconomic instability, a constraint to economic growth, and an ineffective and/or inequitable provider of retirement income."

Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Applications of Activated Sludge Models written by Damir Brdjanovic and published by IWA Publishing. This book was released on 2015-02-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.

Download or read book Automotive Fuels Reference Book written by Paul Richards and published by SAE International. This book was released on 2014-03-05 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first two editions of this title, published by SAE International in 1990 and 1995, have been best-selling definitive references for those needing technical information about automotive fuels. This long-awaited new edition has been thoroughly revised and updated, yet retains the original fundamental fuels information that readers find so useful. This book is written for those with an interest in or a need to understand automotive fuels. Because automotive fuels can no longer be developed in isolation from the engines that will convert the fuel into the power necessary to drive our automobiles, knowledge of automotive fuels will also be essential to those working with automotive engines. Small quantities of fuel additives increasingly play an important role in bridging the gap that often exists between fuel that can easily be produced and fuel that is needed by the ever-more sophisticated automotive engine. This book pulls together in a single, extensively referenced volume, the three different but related topics of automotive fuels, fuel additives, and engines, and shows how all three areas work together. It includes a brief history of automotive fuels development, followed by chapters on automotive fuels manufacture from crude oil and other fossil sources. One chapter is dedicated to the manufacture of automotive fuels and fuel blending components from renewable sources. The safe handling, transport, and storage of fuels, from all sources, are covered. New combustion systems to achieve reduced emissions and increased efficiency are discussed, and the way in which the fuels’ physical and chemical characteristics affect these combustion processes and the emissions produced are included. There is also discussion on engine fuel system development and how these different systems affect the corresponding fuel requirements. Because the book is for a global market, fuel system technologies that only exist in the legacy fleet in some markets are included. The way in which fuel requirements are developed and specified is discussed. This covers test methods from simple laboratory bench tests, through engine testing, and long-term test procedures.

Download or read book Boundaries written by Christine E. Gudorf and published by Georgetown University Press. This book was released on 2010-04-15 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.

Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Download or read book Democracy in America Complete written by Alexis de Tocqueville and published by Library of Alexandria. This book was released on 2020-09-28 with total page 1320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amongst the novel objects that attracted my attention during my stay in the United States, nothing struck me more forcibly than the general equality of conditions. I readily discovered the prodigious influence which this primary fact exercises on the whole course of society, by giving a certain direction to public opinion, and a certain tenor to the laws; by imparting new maxims to the governing powers, and peculiar habits to the governed. I speedily perceived that the influence of this fact extends far beyond the political character and the laws of the country, and that it has no less empire over civil society than over the Government; it creates opinions, engenders sentiments, suggests the ordinary practices of life, and modifies whatever it does not produce. The more I advanced in the study of American society, the more I perceived that the equality of conditions is the fundamental fact from which all others seem to be derived, and the central point at which all my observations constantly terminated. I then turned my thoughts to our own hemisphere, where I imagined that I discerned something analogous to the spectacle which the New World presented to me. I observed that the equality of conditions is daily progressing towards those extreme limits which it seems to have reached in the United States, and that the democracy which governs the American communities appears to be rapidly rising into power in Europe. I hence conceived the idea of the book which is now before the reader. It is evident to all alike that a great democratic revolution is going on amongst us; but there are two opinions as to its nature and consequences. To some it appears to be a novel accident, which as such may still be checked; to others it seems irresistible, because it is the most uniform, the most ancient, and the most permanent tendency which is to be found in history. Let us recollect the situation of France seven hundred years ago, when the territory was divided amongst a small number of families, who were the owners of the soil and the rulers of the inhabitants; the right of governing descended with the family inheritance from generation to generation; force was the only means by which man could act on man, and landed property was the sole source of power. Soon, however, the political power of the clergy was founded, and began to exert itself: the clergy opened its ranks to all classes, to the poor and the rich, the villein and the lord; equality penetrated into the Government through the Church, and the being who as a serf must have vegetated in perpetual bondage took his place as a priest in the midst of nobles, and not infrequently above the heads of kings. The different relations of men became more complicated and more numerous as society gradually became more stable and more civilized. Thence the want of civil laws was felt; and the order of legal functionaries soon rose from the obscurity of the tribunals and their dusty chambers, to appear at the court of the monarch, by the side of the feudal barons in their ermine and their mail. Whilst the kings were ruining themselves by their great enterprises, and the nobles exhausting their resources by private wars, the lower orders were enriching themselves by commerce. The influence of money began to be perceptible in State affairs. The transactions of business opened a new road to power, and the financier rose to a station of political influence in which he was at once flattered and despised. Gradually the spread of mental acquirements, and the increasing taste for literature and art, opened chances of success to talent; science became a means of government, intelligence led to social power, and the man of letters took a part in the affairs of the State. The value attached to the privileges of birth decreased in the exact proportion in which new paths were struck out to advancement. In the eleventh century nobility was beyond all price; in the thirteenth it might be purchased; it was conferred for the first time in 1270; and equality was thus introduced into the Government by the aristocracy itself.

Download or read book Cradle to Cradle written by William McDonough and published by North Point Press. This book was released on 2010-03-01 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.

Download or read book Early Greek Science written by G E R Lloyd and published by Random House. This book was released on 2012-09-30 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this new series leading classical scholars interpret afresh the ancient world for the modern reader. They stress those questions and institutions that most concern us today: the interplay between economic factors and politics, the struggle to find a balance between the state and the individual, the role of the intellectual. Most of the books in this series centre on the great focal periods, those of great literature and art: the world of Herodotus and the tragedians, Plato and Aristotle, Cicero and Caesar, Virgil, Horace and Tacitus. This study traces Greek science through the work of the Pythagoreans, the Presocratic natural philosophers, the Hippocratic writers, Plato, the fourth-century B.C. astronomers and Aristotle. G. E. R. Lloyd also investigates the relationships between science and philosophy and science and medicine; he discusses the social and economic setting of Greek science; he analyses the motives and incentives of the different groups of writers.

Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. 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.
