This book was released on 2002 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este proyecto tuvo como objetivo evaluar técnica y económicamente dos sistemas de riego por aspersión, Pivote central y Cobertura total en remolacha, instalados en el kilómetro 8 camino Coihueco, octava región del Bío-Bío, con el propósito de dar respuesta de la conveniencia de su instalación y al manejo de estos equipos. La evaluación técnica demostró que el pivote central se encuentra operando en buenas condiciones, según resultados de coeficiente de uniformidad del 84,7%, eficiencia de distribución total del 73,3% eficiencia de aplicación del agua del 89,1% y una eficiencia de reposición de agua del 77,9% todas ellas consideradas adecuadas, al igual que la programación del riego. para el equipo de cobertura total los resultados de coeficiente de uniformidad del 71,8%, eficiencia de distribución total del 74,6%, eficiencia de aplicación de agua del 81,2% y eficiencia de reposición de agua de 61,8% permiten establecer que, en general, el riego no es adecuado y que la cantidad de agua aplicada no cumple satisfactoriamente con las necesidades del cultivo para ese suelo. Es recomendable aumentar el tiempo de riego o disminuir la frecuencia de éste, para mantener un mayor contenido de humedad entre cada riego. El costo anual equivalente por hectárea del equipo de cobertura total se encuentra entre 18,4 y 21,7 U.F./año, estos valores son mayores que para el equipo de pivote central que oscila entre 16,1 y 19,1 U.F./año, según varía la tasa de interés y valores residuales considerados. Se concluye que desde el punto de vista económico y de deficiencias en el riego, es más conveniente implementar el equipo de pivote central.

Download or read book Glosario Del Banco Mundial written by World Bank and published by World Bank Publications. This book was released on 1996 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Download or read book Therapeutic Landscapes written by Allison Williams and published by Routledge. This book was released on 2017-05-15 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The therapeutic landscape concept, first introduced early in the 1990s, has been widely employed in health/medical geography and gaining momentum in various health-related disciplines. This is the first book published in several years, and provides an introduction to the concept and its applications. Written by health/medical geographers and anthropologists, it addresses contemporary applications in the natural and built environments; for special populations, such as substance abusers; and in health care sites, a new and evolving area - and provides an array of critiques or contestations of the concept and its various applications. The conclusion of the work provides a critical evaluation of the development and progress of the concept to date, signposting the likely avenues for future investigation.
Download or read book A Tale of Seven Scientists and a New Philosophy of Science written by Eric Scerri and published by Oxford University Press. This book was released on 2016-10-10 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his latest book, Eric Scerri presents a completely original account of the nature of scientific progress. It consists of a holistic and unified approach in which science is seen as a living and evolving single organism. Instead of scientific revolutions featuring exceptionally gifted individuals, Scerri argues that the "little people" contribute as much as the "heroes" of science. To do this he examines seven case studies of virtually unknown chemists and physicists in the early 20th century quest to discover the structure of the atom. They include the amateur scientist Anton van den Broek who pioneered the notion of atomic number as well as Edmund Stoner a then physics graduate student who provided the seed for Pauli's Exclusion Principle. Another case is the physicist John Nicholson who is virtually unknown and yet was the first to propose the notion of quantization of angular momentum that was soon put to good use by Niels Bohr. Instead of focusing on the logic and rationality of science, Scerri elevates the role of trial and error and multiple discovery and moves beyond the notion of scientific developments being right or wrong. While criticizing Thomas Kuhn's notion of scientific revolutions he agrees with Kuhn that science is not drawn towards an external truth but is rather driven from within. The book will enliven the long-standing debate on the nature of science, which has increasingly shied away from the big question of "what is science?"
Download or read book Encounters with Popular Pasts written by Mike Robinson and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the recognition that heritage is popular and popular culture is now readily transformed into heritage, whose meanings and myths reshape social life and political and economic realities, as well as re-make "tradition". The papers in this volume consider: What does popular heritage look like? To whom does it speak? Is it active in dissolving class and cultural boundaries or just in reproducing new ones? How do societies manage a heritage that is fluid, immediate and that straddles extremes of serious conflict and hedonistic frivolity? When and under what circumstances is the creation and expression of new cultural forms - popular culture - capable of being transformed into heritage?
