Primitive Meteorites and Asteroids: Physical, Chemical, and Spectroscopic Observations Paving the Way to Exploration covers the physical, chemical and spectroscopic aspects of asteroids, providing important data and research on carbonaceous chondrites and primitive meteorites. This information is crucial to the success of missions to parent bodies, thus contributing to an understanding of the early solar system. The book offers an interdisciplinary perspective relevant to many fields of planetary science, as well as cosmochemistry, planetary astronomy, astrobiology, geology and space engineering. Including contributions from planetary and missions scientists worldwide, the book collects the fundamental knowledge and cutting-edge research on carbonaceous chondrites and their parent bodies into one accessible resource, thus contributing to the future of space exploration.

The paradox of U.S. involvement in Southeast Asia The Obama administration's pivot-to-Asia policy establishes an important place for Southeast Asia in U.S. foreign policy. But Washington's attention to the region has fluctuated dramatically, from the intense intervention of the cold war era to near neglect in more recent years. As a consequence, countries in Southeast Asia worry that the United States once again will become distracted by other problems and disengage from the region. This book written by an astute observer of the region and U.S. policy casts light on the sources of these anxieties. A main consideration is that it still is not clear how Southeast Asia fits into U.S. strategy for Asia and the broader world. Is the region central to U.S. policymaking, or an afterthought? Ambivalent Engagement highlights a dilemma that is becoming increasingly conspicuous and problematic. Southeast Asia continues to rely on the United States to play an active role in the region even though it is an external power. But the countries of Southeast Asia have very different views about precisely what role the United States should play. The consequences of this ambivalence will grow in importance with the expanding role of yet another outside power, China.

It's happening now-plans are being formulated under the coordination of NASA to launch a permanent, manned space station by the year 1990. Studies surveying user requirements, system attributes, and architectural options have been conducted, and you're on the top of these far-reaching considerations on the next big step taken within space! Now that the Shuttle and Spacelab are realities, NASA has set sights on a new horizon-a permanent, manned space station in the high frontier. The precedents have been set-Skylab hosted human visits for up to 84 days, and the Soviet's Salyut was and is a temporary base for cosmonaut crew. The differences are the term and scope of space station living and the accomplishments that can be realized with a permanent site and continuous experimentation within its facilities. Brian O'Leary, writer, astrophysicist, and former astronaut, describes the "tinkermodules" that will be carried to the earth's orbit to be assembled as a space station. His inside track information also lay

An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Profitability and socioeconomic impact of mining operations are influenced by the choice of cut-off grades. Cut-off grades play a key role in estimating mineral reserves that can be publicly reported.

This new edition is easier to read and of greater practical interest to practitioners. The relationship between optimization of net present value, capacity constraints, and opportunity cost is explained in greater detail. A new section discusses blending strategies, which play a critical role in an increasing number of mining operations.

Author Jean-Michel Rendu, an internationally recognized expert in the management, estimation, and public reporting of mineral resources, provides practical insights. As a manager in major mining companies, a consultant, and an educator, Rendu has acquired considerable experience in all aspects of mining engineering, experience that was incorporated into this publication.

This is a must-read for mine managers, analysts, geologists, mining engineers, and public policymakers who want to stay on the leading edge of their profession.
