This book was released on 2013 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: El presente libro, tiene como objetivo principal hacer una propuesta de evaluacion de los agregados para pavimentos de concreto. Se estudio el comportamiento de los agregados (grava y arena), para obtener las propiedades fisicas y mecanicas de los materiales utilizados en pavimentos de concreto con cemento Portland, y conocer la interrogante de los materiales que son deseables a los intereses y necesidades en las mezclas de concreto. Se clasificaron las diferentes plantas de concreto, se obtuvieron muestras de agregados para conocer sus propiedades, las cuales tienen una influencia en la calidad del concreto y son de gran interes. Lo anterior nos permitio deducir y evaluar el grado de calidad de las caracteristicas de los concretos y su posible comportamiento; pero se le dio mas enfasis a los agregados debido a que la eleccion de materiales apropiados tiene una mayor importancia en el aspecto tecnico y economico.

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 Times Gone By written by Vicente Pérez Rosales and published by Oxford University Press. This book was released on 2003-05-01 with total page 432 pages. 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.

Download or read book Soil Survey Manual U S Department of Agriculture Handbook No 18 written by U.S. Department of Agriculture and published by Lulu.com. This book was released on 2019-04-06 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Soil Survey Manual, USDA Handbook No. 18, provides the major principles and practices needed for making and using soil surveys and for assembling and using related data. The term ?soil survey? is used here to encompass the process of mapping, describing, classifying, and interpreting natural three-dimensional bodies of soil on the landscape. This work is performed by the National Cooperative Soil Survey in the United States and by other similar organizations worldwide. The Manual provides guidance, methodology, and terminology for conducting a soil survey but does not necessarily convey policies and protocols required to administer soil survey operations. The soil bodies contain a sequence of identifiable horizons and layers that occur in repeating patterns in the landscape as a result of the factors of soil formation as described by Dokuchaev (1883) and Jenny (1941).
Download or read book Weak and Diffuse Modernity written by Andrea Branzi and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Weak and Widespread, modernity stands as a contrasting operative practice when compared to that of the 20th century, which was based on finding definitive solutions to old and new problems of industrial society. Today's architecture and urban planning tends to operate through reversible solutions, taking their references from models that are incomplete, imperfect and elastic. Precisely for this reason they are capable of withstanding the continuous processes of innovation. In this book Branzi examines how transformations in the concept of modernity have changed project strategy following new territorial and social developments. He puts this into relation to his own projects and research from the mid-1960's with the radical experience of the Archizoom group until the present.
Download or read book Analogous and Digital written by Otl Aicher and published by John Wiley & Sons. This book was released on 2015-04-27 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Otl Aicher (1922-1991) was an outstanding personality in modern design, he was a co-founder of the legendary Hochschule fur Gestaltung (HfG), the Ulm School of Design, Germany. His works since the fifties of the last century in the field of corporate design and his pictograms for the 1972 Summer Olympics in Munich are major achievements in the visual communication of our times. "An integral component of Aicher's work is that it is anchored in a "philosophy of making" inspired by such thinkers as Ockham, Kant or Wittgenstein, a philosophy concerned with the prerequisites and aims, the objects and claims, of design. Aicher's complete theoretical and practical writings on design (which include all other aspects of visual creativity, such as architecture) are available with this new edition of the classic work. If Aicher prefers the analogous and concrete to the digital and abstract he does it with a philosophical intention. He relativizes the role of pure reason. He criticizes the rationality of Modernism as a result of the dominance of purely abstract thinking. Anyone who prefers the abstract to the concrete does not only misunderstand the mutual dependence of concept and view. In Aicher's judgement he is also creating a false hierarchy, a rank order that is culturally fatal. Things that are digital and abstract are not greater, higher and more important than things that are analogous and concrete." Wilhelm Vossenkuhl
Download or read book Fire Design of Concrete Structures Materials Structures and Modelling written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2007-01-01 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire design of concrete structures has emerged in recent years as a high profile subject of great interest to both experts and the public. This has been largely prompted by severe damage to concrete in a number of recent tunnel fires, as well as a considerable amount of research and development that has taken place world-wide. fib Task Group 4.3, "Fire Design of Concrete Structures", therefore took the initiative to develop this bulletin in order to present the results of this international research to a wider group of concrete professionals. The report presents a general brief outline of the effect of fire on both concrete material and concrete structures, with emphasis placed on the important developments of the past few years, namely: (a) the increasing use of high strength concrete (HSC) in buildings, tunnels and bridges; (b) the growing acceptance of the use of performance based fire engineering calculations for the structural analysis and design against fire; (c) the problem of, and solutions to, explosive spalling; and (d) fires in tunnels. This report is not intended to be an exhaustive review of the effect of fire on concrete and concrete structures, nor to present a database of properties at high temperature. Instead, the main aims of this document are to present recent trends and developments, highlight key influencing factors, bring together the disparate but related issues in one short document, highlight the deficiencies in current practice and point to the future. The basic principles of performance based codes and fire engineering are also presented on the assumption that the reader is not a specialist in this field.
Download or read book Application of Bacterial Pigments as Colorant written by Wan Azlina Ahmad and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand for natural dyes as natural dyes exhibit better biodegradability and generally have a higher compatibility with the environment. However, one of the limitations on the use of natural dyes or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw material). Therefore, the exploitation of other biological sources such as fungi, bacteria and cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins offer the advantage in terms of production compared to pigments extracted from vegetables or animals, due to its simple cell and fast culturing technique. This book offers interesting insight into initial works carried out to demonstrate the potential use of bacterial pigment as colorant for various applications.
Download or read book From Where We Stand written by Deborah Tall and published by Syracuse University Press. This book was released on 2016-05-05 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why does a particular landscape move us? What is it that attaches us to a particular place? Tall’s From Where We Stand is an eloquent exploration of the connections we have with places—and the loss to us if there are no such connections. A typically rootless child of several American suburbs, Tall set out to make a true home for herself in the landscape that circumstance had brought her—the Finger Lakes region of upstate New York. In a mosaic of personal anecdotes, historical sketches, and lyrical meditations, she interweaves her own story with the story of this place and its people—from the Seneca Nation of the Iroquois, to European settlers, to the many utopians who sensed and were inspired by a spiritual resonance here. This edition includes an introduction by William Kittredge and a foreword by Stephen Kuusisto, both highlighting the book’s significance and Tall’s exquisite skill in tracing the relationship between homelands and storytelling.
