This book was released on 2014-06-30 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: La Laguna de Yuriria localizada en la parte sur del Estado de Guanajuato, Mexico, sufre un fuerte proceso de eutroficacion originado por las descargas de agua residual provenientes de las localidades rurales situadas en su periferia, los arrastres de las precipitaciones pluviales producto de la pendiente natural del terreno y un deficit en el sistema de alcantarillado de la region, causando el detrimento de la flora y fauna acuatica. Se desarrollo una solucion preventiva para la proteccion y conservacion de este cuerpo lacustre mediante la implementacion de un sistema de tratamiento en cada localidad riberena basado en humedales artificiales. El diseno y construccion del sistema se fundamenta en principios de ingenieria, datos de campo y estudios extensos a nivel piloto. Para la experimentacion a nivel laboratorio se trabajo con Typha domingensis y se analizo su comportamiento en la remocion de contaminantes para humedales de flujo libre superficial y subsuperficial con la finalidad de validar los modelos resultantes mediante pruebas de campo que fueron realizadas en una planta piloto. Estos datos permitieron efectuar el escalamiento de la planta para las diferentes localidades."
Download or read book Water Pollution XIV written by S. Hernández and published by WIT Press. This book was released on 2018-08-21 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water pollution problems are of continued importance around the world, with an impact on both populated areas and the environment. This volume consists of papers presented at the 14th International Conference in the series of Monitoring, Modelling and Management of Water Pollution. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies requires the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement, to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential. Topics covered include: Water contamination; Monitoring, modelling and forecasting; Water management; Wastewater management; Groundwater and aquifers; Flood damage; Freshwater quality; Coastal and offshore pollution; Health risk studies; Agricultural contamination; Industrial pollution; Water reuse; Emerging technologies; Socio-economic-political consequences; Population and climate change; Education and training.

This book was released on 2021-06-25 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faced with chaotic environments, it is not possible to make totally efficient forecasts, especially when it is necessary to analyze events with multiple variables and micro, small, and medium enterprises (MSMEs) constantly face events that escape the laws of the market. The handling that has been given to the crisis caused by the coronavirus has been trial and error, and the economic, social, and environmental results remain to be seen. The markets and the world are chaotic. With the markets in chaos due to the COVID-19 pandemic, it is important to look at the methods used in these environments to promote business success. The Handbook of Research on Management Techniques and Sustainability Strategies for Handling Disruptive Situations in Corporate Settings elaborates on the skills, techniques, and tools that are more useful for these environments and identifies what makes companies that work well in organizational chaos and in chaotic economic environments perform better than companies that are well organized. Covering topics such as strategic management, multidimensional chaos approach, and the global unstable market, this book is essential for managers, executives, academicians, policymakers, entrepreneurs, researchers, undergraduate and graduate business students, and any person interested in state-of-the-art business issues.

Download or read book Wastewater Treatment in Constructed Wetlands with Horizontal Sub Surface Flow written by Jan Vymazal and published by Springer Science & Business Media. This book was released on 2008-07-15 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.

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 From Grammar to Meaning written by Ivano Caponigro and published by Cambridge University Press. This book was released on 2013-09-12 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the study of formal semantics and formal pragmatics has grown tremendously, showing that core aspects of language meaning can be explained by a few principles. These principles are grounded in the logic that is behind - and tightly intertwined with - the grammar of human language. In this book, some of the most prominent figures in linguistics, including Noam Chomsky and Barbara H. Partee, offer new insights into the nature of linguistic meaning and pave the way for the further development of formal semantics and formal pragmatics. Each chapter investigates various dimensions in which the logical nature of human language manifests itself within a language and/or across languages. Phenomena like bare plurals, free choice items, scalar implicatures, intervention effects, and logical operators are investigated in depth and at times cross-linguistically and/or experimentally. This volume will be of interest to scholars working within the fields of semantics, pragmatics, language acquisition and psycholinguistics.
