Various physical and chemical properties of individual plastics presently used for welded construction are completely covered in this volume, with regard to their use in chemical and allied processing. All presently known techniques of welding are covered in detail and there are many step-by-step procedures with photographs. One of the most complete corrosion resistance tables yet published is included, plus a concise guide for the choice of an appropriate plastic construction material. This text will be of substantial help to engineers and manufacturers who are interested in present and potential applications in the process industries. LUBRICAUON

This book represents Volume II in the Transactions of the American Society of Lubrication Engineers, constituting a valuable group of papers on widely diverse fields of lubrication. The papers are all written by leaders in their respective fields giving a source of reference not only for those concerned directly with lubrication, but also to many industrial research engineers and designers.

ATOM AND THE ENERGY REVOLUTION,
by Norman 6 X 9” in. brary,‘19.58.
Lansdell. 200 pages, plates, New York, Philosophical LiPrice, $6.00.
In this book Lansdell presents a balanced study of the role of atomic energy in the world of today and tomorrow. He concerns himself only .with the peaceful uses of energy, including t.he atom. The issue is the reorientation of human life and society, the impact of power development on other spheres of activity (on other industrial techniques, private industry, and the balance of world trade). The book is addressed to the specialist to acquaint him with other disciplines, to the business man who must adjust to the new industrial and commercial factors introduced by atomic energy, to the citizen to show him the social and political implications of the

new sources of energy, their potentialities, demands, and possible cost. The serious problems which must arise during the next fifty years, arising from the world pattern of energy demand, are neither the same nor equally crucial all over the world. New sources of energy are required 011 different scales (large stations delivering power and/or heat, medium and small fixed units, and mobile units). Such sources are wind and water power, vegetable resources, solar energy, electro-chemical generation of energy, direct conversion of radiation into electric current, nuclear fission, nuclear fusion, and the annihilation of matter. Present atomic energy developments relate mainly to large units. The structure of the atom and its energy are analyzed. The study of the methods of releasing atomic energy is illustrated with 32 plates. Lansdell shows the sources of natural materials for atomic energy development, the exploitation of atomic energy, the political and commercial organizations for atomic energy development, national and international. radiation Asks, and insurance against them. MATHEMATICAL METHODS OF OPERATIONS RESEARCH, by Thomas L. Saaty. 421 pages, diagrams, 6 X 9 in. New York, McGraw-Hill BookCo., Inc. 1959. Price, $10.00. Operationsresearch-thescientificapproach to operational problems for the greater fulfillment of objectives-is a parallel development to an increased realization of the usefulness of staff planning and analysis functions. The implementation of these functions has led to rapid development of new methodology, and application of old methodology to new problems. The book requires for background a course in calculus, some advanced calculus and rudimentary matrix theory, and some analytical experience. Part I of this study gives background perspective. The chapter on mathematical models illustrates, by brief discussions and examples, how the need for such tools arises, and some types of related theoretical questions. Part II treats of optimism and some of its problems, linear and quadratic programming, and the theory of games.
