Download or read book Management and Ecology of Freshwater Plants written by Joseph Caffrey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
Download or read book Hydrogeology written by Bernward Hölting and published by Springer. This book was released on 2018-06-25 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a complete introduction to Hydrogeology. It is a comprehensive reference for earth science professionals involved in groundwater exploitation as well as for geotechnical engineers. This English translation of the German textbook "Hydrogeologie" by Hölting & Coldewey, which has been published in its 8th edition, provides insights into the sources and reservoirs of groundwater, the dynamics of fluid flow, and the physical and chemical composition of groundwater. It also gives an overview about the economic value of groundwater and its exploitation and use. A consistent use of the internationally accepted SI units as well as the formula symbols in the text contributes to the understandability.
Download or read book Potash written by D.E. Garrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potash is the term generally given to potassium chloride, but it is also loosely applied to the various potassium compounds used in agriculture: po tassium sulfate, potassium nitrate or double salts of potassium and magne sium sulfate (generally langbeinite, K S0 • 2MgS0 ). Sometimes the var 2 4 4 ious compounds are differentiated by the terms muriate of potash, sulfate of potash, etc. When referring to ores, or in geology, all of the naturally found potassium salts are called "potash ores". However, originally potash referred only to crude potassium carbonate, since its sole source was the leaching of wood ashes in large pots. This "pot ash" product was generally recovered from near-seacoast plants, such as the saltwort bush, whose ashes were richer in potassium than sodium carbonate. Inland plant's ashes were generally higher in sodium carbonate, giving rise to the word alkali from the Arabic word for soda ash, al kali. The term was then carried over after potassium was discovered to form the latin word for it, kalium. The recovery of potash from ashes became a thriving small cottage industry throughout the world's coastal areas, and developing economies, such as the early set tlers in the United States were able to generate some much-needed income from its recovery and sale. This industry rapidly phased out with the advent of the LeBanc process for producing soda ash in 1792, and the discovery about the same time of the massive sodium-potassium nitrate deposits in the Atacama Desert of Chile.
Download or read book System of Environmental economic Accounting for Water written by United Nations. Statistical Division and published by . This book was released on 2012 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System of Environmental-Economic Accounting for Water, commonly referred to as SEEA-Water, is a conceptual framework for the organization of physical and economic information, developed with the purpose of providing an integrated conceptual framework to support water policy design and evaluation. It uses concepts, definitions and classifications coherent with those of the System of National Accounts. SEEA-Water is a subsystem of the System of Environmental-Economic Accounting (SEEA), which provides internationally agreed standards for the compilation of measures about the environment and its interactions with the economy. After a rigorous consultation process, SEEA-Water was adopted in 2007 by the United Nations Statistical Commission (UNSC). Part I of SEEA-Water has been adopted as an interim international statistical standard subject to re-evaluation when the SEEA is adopted as an international statistical standard.

Download or read book Alternative Energy Sources written by Efstathios E. Stathis Michaelides and published by Springer Science & Business Media. This book was released on 2012-01-16 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alternative Energy Sources is designed to give the reader, a clear view of the role each form of alternative energy may play in supplying the energy needs of the human society in the near future (20-50 years). The two first chapters on "energy demand and supply" and "environmental effects," set the tone as to why alternative energy is essential for the future. The third chapter gives the laws of energy conversion processes, as well as the limitations of converting one energy form to another. The section on exergy gives a quantitative background on the capability/potential of each energy source to produce power. The fourth, fifth and sixth chapters are expositions of fission and fusion nuclear energy, the power plants that may produce power from these sources and the issues that will frame the public debate on nuclear energy. The following five chapters include descriptions of the most common renewable energy sources (wind, solar, geothermal, biomass, hydroelectric) some of the less common sources (e.g. tidal and wave energy). The emphasis of these chapters will be on the global potential of each source, the engineering/technical systems that are used in harnessing the potential of each source, the technological developments that will contribute to wider utilization of the sources and environmental effects associated with their wider use. The last three chapters are: "energy storage," which will become an important issue if renewable energy sources are used widely. The fourteen chapters in the book have been chosen so that one may fit a semester University course around this book. At the end of every chapter, there are 10-20 problems and 1-3 suggestions of semester projects that may be assigned to students for further research.
