This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book The Soils of Mexico written by Pavel Krasilnikov and published by Springer Science & Business Media. This book was released on 2013-02-12 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.

Download or read book Silvopastoral Systems in Southern South America written by Pablo Luis Peri and published by Springer. This book was released on 2016-03-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

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 Improving Science Education written by Millar, John and published by McGraw-Hill Education (UK). This book was released on 2000-12-01 with total page 382 pages. 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.

Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Download or read book Mahatma Gandhi written by Dennis Dalton and published by Columbia University Press. This book was released on 2012-02-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.

Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.
