Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Available in PDF, EPUB and Kindle. Book excerpt: This book takes stock of where we are in science education research, and considers where we ought now to be going. It explores how and whether the research effort in science education has contributed to improvements in the practice of teaching science and the science curriculum. It contains contributions from an international group of science educators. Each chapter explores a specific area of research in science education, considering why this research is worth doing, and its potential for development. Together they look candidly at important general issues such as the impact of research on classroom practice and the development of science education as a progressive field of research. The book was produced in celebration of the work of the late Rosalind Driver. All the principal contributors to the book had professional links with her, and the three sections of the book focus on issues that were of central importance in her work: research on teaching and learning in science; the role of science within the school curriculum and the nature of the science education we ought to be providing for young people; and the achievements of, and future agenda for, research in science education.

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.

Available in PDF, EPUB and Kindle. Book excerpt: These memoirs trace the wild and adventurous life of Pérez Rosales from his childhood up to the 1860s. During that approximately half-century he saw and did more than a dozen ordinary men. At age eleven in Argentina he witnessed the executions of Luis and Juan Jose Carrera. From there, his activities and adventures took him on several journeys on sailing vessels around Cape Horn; to Paris, where he witnessed the July revolution of 1830; to various commercial endeavors including a distillery, the practice of medicine, and cattle smuggling; into service as an advisor to an Argentine warlord; as a miner for precious metals in the north of Chile; as participant in the California Gold Rush in 1849; as director of the government's project for German immigration and settlement in the wild south of Chile; and also as Chilean consul and immigration agent in Hamburg. Around the world, Rosales lived through many of his era's watershed moments. His exciting memoirs offer a chance to relive the rush and chaos of these times--from a much safer vantage.

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.

Book excerpt: Walter Lippmann wrote his "Public Opinion" at a time when something like the 'mass media' was coming into existence. Prior to the age of electronic communication, the only mechanism for reaching large numbers of individuals was the newspapers. In World War I, he saw how opportunistic nations used the newspapers to serve their often nefarious aims. Lippmann, however, believed that in the hands of super-intelligent, disinterested, omni-benevelont 'experts, ' the 'mass media' could bring about world peace. The school system, the advent of radio, and of course, the television, were arriving or coming along shortly. Each allowed a small group of people the ability to manage a much larger group, inspiring optimism among liberals and progressives that with the right forumula, the horrors seen in World War I would never occur again. Lippmann wrote "Public Opinion" in 1922, shortly after World War I. In 1924, a certain Adolf Hitler would be spending time in jail. If this merited any mention in any newspaper, it is doubtful that no expert paid it any mind. 1939 was, after all, a long way off.
