Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

This book was released on 2002-03-14 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.

This book was released on 2009-05-07 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study is a slightly revised version of my PhD thesis which was accepted at the Economics Department of Dresden University of Technology in July 2008. It has a long and a short history. For it began, as suggested theme, as a fundamental evaluation of evolutionary economics for ecological economics, asking, especially, for what the two ?elds actually constitutes and, eventually, relates. In several years of unfruitful dwelling, however, neither of these two young, non-mainstream ?elds proved as constituted at a fundamental level as yet. Rather, ecological economics, founded at the end of the 1980s as an attempt to combine social and natural s- ence approaches(in particular economics and ecology) to study especially long-run environmental problems in an encompassing manner, has mainly developed into an interdisciplinary research forum on environmental-economicissues. Particularly uni?edbycertainnormativestances sharedwithinits community,it constitutes,well understood, a new discpline of its own right, distinct from economics, with its own scienti?c standards, questions, methodologies and institutions (Baumgartner ̈ and Becker 2005). Modern evolutionaryeconomicson the other hand has been a quarter of a century after its inception with Nelson and Winter (1982) still a mainly h- erogeneousendeavor, linked by a (rather amorphous) common interest in economic “evolution” and a critical stance towards neoclassical mainstream economics, with a certain strength in applied studies on industrial dynamics (Heinzel 2004, 2006).

Book excerpt: Coal is a natural resource that is highly valued for its energy content. The steel and cement industries depend on coal for the extraction of iron from iron ore and for the manufacture of cement. The process of extracting coal from a coal pit is known as coal mining. The technical and economic feasibility of a coal extraction process depend on coal seam continuity, thickness, quality, depth, overburden characteristics, topography, surface drainage patterns, etc. Mining can be done on the surface or deep underground. Strip mining, contour mining and mountaintop removal mining are the three primary types of surface mining. There have been several strides in technological advancements in coal mining in recent times. The use of sophisticated sensing equipment for monitoring air quality, hazardous gas monitoring, gas drainage, improved mining techniques, and the employment of highly skilled task force adept at the use of complex state-of-the-art equipment has made coal mining productive and safe. This book provides comprehensive insights into coal mining. It discusses the fundamentals as well as modern approaches of coal mining. Those in search of information to further their knowledge will be greatly assisted by this book.

Available in PDF, EPUB and Kindle. Book excerpt: This is a study of how, and why, the British economy has changed since 1951. It covers the Golden Age of 1945-1973 when unemployment was below one million; when governments built millions of council houses and flats; when electricity, telephones, and gas were supplied by nationalised monopolies; when income and wealth inequality were narrowing; and when the UK was not a member of the European Economic Community. Moving through the inflation, rising unemployment, and rapid contraction of the manufacturing industry from the mid- 1970s, Changing Times examines the transfer of assets which was effected in the privatisation of public housing and nationalised industries from the early 1980s. The role of the State changed as public investment fell. The financing of old-age care, of state pensions, and of the National Health Service became of increasing concern and were less politically amenable to the approach of using private finance (the Private Finance Initiative and tuition fees) to fund former public obligations. Changes were made to the system of taxation, but public expenditure changed little as a share of national income, although the government now built little. Difficulties emerged in ensuring adequate housing for a growing population, and uncertainty grew as to where future investment in necessities like electricity supply would come from. Having narrowed in the Golden Age, inequality of income and wealth widened. Environmental concerns also grew, from the local smogs of the 1950s, through the concern with acid rain from the 1960s, to the current global concern with climate change. The financial crash of 2008 and the decision to 'Brexit' in the referendum of 2016 reduced economic growth and highlighted the extent of economic change since 1951. This is a study of that change.
