Evaluation of Soil and Rock Properties PDF Author: P. J. Sabatini
Publisher:
ISBN: 9781410217615
Category : Technology & Engineering
Languages : en
Pages : 392

Book Description
This document presents state-of-the-practice information on the evaluation of soil and rock properties for geotechnical design applications. This document addresses the entire range of materials potentially encountered in highway engineering practice, from soft clay to intact rock and variations of materials that fall between these two extremes. Information is presented on parameters measured, evaluation of data quality, and interpretation of properties for conventional soil and rock laboratory testing, as well as in situ devices such as field vane testing, cone penetration testing, dilatometer, pressuremeter, and borehole jack. This document provides the design engineer with information that can be used to develop a rationale for accepting or rejecting data and for resolving inconsistencies between data provided by different laboratories and field tests. This document also includes information on: (1) the use of Geographical Information Systems (GIS) and Personal Data Assistance devices for the collection and interpretation of subsurface information; (2) quantitative measures for evaluating disturbance of laboratory soil samples; and (3) the use of measurements from geophysical testing techniques to obtain information on the modulus of soil. Also included are chapters on evaluating properties of special soil materials (e.g., loess, cemented sands, peats and organic soils, etc.) and the use of statistical information in evaluating anomalous data and obtaining design values for soil and rock properties. An appendix of three detailed soil and rock property selection examples is provided which illustrate the application of the methods described in the document.

Introduction to Industrial Polypropylene

Introduction to Industrial Polypropylene PDF Author: Dennis B. Malpass
Publisher: John Wiley & Sons
ISBN: 111846320X
Category : Technology & Engineering
Languages : en
Pages : 290

Book Description
This introductory text is an important resource for new engineers, chemists, students, and chemical industry personnel to understand the technical aspects of polypropylene which is the 2nd largest synthetics polymer in manufactured output. The book considers the following topics: What are the principal types of polypropylene and how do they differ? What catalysts are used to produce polypropylene and how do they function? What is the role of cocatalysts and how have they evolved over the years? How are industrial polypropylene catalysts tested and the resultant polymer evaluated? What processes are used in the manufacture of polypropylene? What are the biopolymer alternatives to polypropylene? What companies are the major industrial manufacturers of polypropylene? What is the environmental fate of polypropylene?

Wetlands

Wetlands PDF Author: Committee on Characterization of Wetlands
Publisher: National Academies Press
ISBN: 0309587220
Category : Science
Languages : en
Pages : 329

Book Description
"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Winds of Change

Winds of Change PDF Author: Transportation Research Board
Publisher: Transportation Research Board
ISBN: 9780309051040
Category : Business & Economics
Languages : en
Pages : 420

Book Description
Commercial aviation was one of the first industries affected by the controversial regulatory reforms that began in the 1970s. Beginning in 1975, administrative reforms of the Civil Aeronautics Board gave carriers greater freedom in discounting prices and serving new markets. The Airline Deregulation Act of 1978 removed restrictions on entry, pricing, and routes. Still unresolved in policy and practice, however, is the question of the appropriate role of government. In the interest of informing the public debate about deregulation, the Executive Committee of the Transportation Research Board convened a committee of 15 experts to review air passenger service and safety since deregulation. The findings of the committee and its recommendations are presented in this report.

History of Jacksonville, Florida and Vicinity, 1513 to 1924

History of Jacksonville, Florida and Vicinity, 1513 to 1924 PDF Author: T. Frederick Davis
Publisher: Jazzybee Verlag
ISBN: 3849660400
Category : History
Languages : en
Pages : 588

Book Description
Two times there was a wholesale destruction of Jacksonville's official records – in the War Between the States and by the fire of May 3, 1901. The author's effort in this work was to collect all of the available authentic matter for permanent preservation in book form. The record closes as of December 31, 1924. The record is derived from many sources – long forgotten books and pamphlets; old letters and diaries that have been stored away as family memorials of the past; newspapers beginning with the St. Augustine Herald in 1822 (on file at the Congressional Library at Washington) fragmentary for the early years, but extremely valuable for historical research; almost a complete file of local newspapers from 1875 to date; from the unpublished statements of old residents of conditions and outstanding events within the period of their clear recollection; and from a multitude of other sources of reliability. The search through the highways and the byways for local history was in the spare moments of the author stretching over a period of a score of years, a pastime "hobby" with no idea of making money out of it. No attempt has been made to discuss the merits of any incident, but only to present the facts, just as they were and just as they are, from the records and sources indicated.
