In the 1970s, members of the U.S. National Committee on Tunneling Technology (USNCTT) recognized a need to review and improve contracting practices for underground construction. The committee conducted an intensive study and several workshop reviews, ultimately publishing a set of recommended practices in 1974.

Convincing interpretations of many ancient glacimarine sequences depend on studies of analogous processes active in modern glacimarine environments. Studies of both ancient glacimarine sequences and modern glacimarine environments have increased in recent years. The time therefore seemed ripe to hold a meeting to bring workers on the contemporary and ancient record together, and so the meeting which generated this volume was conceived. The two-day meeting, organized on behalf of the Marine Studies Group of the Geological Society of London, in conjunction with the International Glaciological Society, and promoted under the aegis of IGCP Project 260, was held in March 1989 at Burlington House in Piccadilly, the London home of the Geological Society. Many of the papers presented at the meeting are contained within this volume <...>

Encyclopedia of Earth and Space Science is a twovolume reference intended to complement the material typically taught in high school Earth science and astronomy classes, and in introductory college geology, atmospheric sciences, and astrophysics courses. The substance reflects the fundamental concepts and principles that underlie the content standards for Earth and space science identified by the National Committee on science Education standards and Assessment of the National Research Council for grades 9–12.

Inorganic oxysalts represent one of the most important and widespread groups of inorganic compounds. They constitute more than half of the mineral species known today, they form in the environment around us, their structure and properties determine a wide range of natural and technological processes. This book deals with the crystallography of inorganic oxysalts, i.e. with a description of the organization of atoms in their crystal structures.

Landforms and landscapes vary enormously across the Earth, from high mountains to endless plains. At a smaller scale, Nature often surprises us by creating shapes which look improbable. Many physical landscapes are so immensely beautiful that they have received the highest possible recognition—they hold the status of World Heritage properties. Apart from often being immensely scenic, landscapes tell stories which not uncommonly can be traced back in time for tens of million years and include unique events.

Обобщены результаты многолетних исследований изменений физико-технических свойств и химического состава торфа на всех стадиях технологического процесса добычи торфа. Представлены данные о количественных и качественных изменениях компонентного состава (углеводов, гуминовых веществ, битумов) различных видов торфа в условиях антропогенно нарушенной торфяной залежи в результате осушения, в процессе влагоудаления при сушке, а также хранении добытого торфа.

Investment decisions are critical part of a company’s success, and capital budgeting is a central topic of financial management. However, in contrast to other strategic decisions in business, decisions on capital projects are decentralized, from corporate to divisions, divisions to operations, from operations to departments. Engineers at various levels within the organization who make a capital proposal are contributing to the strategic success of the organization. This book will assist engineers to contribute strategically to the organization, so that they can contribute to the success of their company and can make a success of their careers.<...>
