Lead 68

Edited Proceedings, Third International Conference on Lead, Venice

Lead 68: Edited Proceedings, Third International Conference on Lead Venice focuses on the compositions, characteristics, uses, and reactions of lead. The selection contains the proceedings of the Third International Conference on Lead held in Venice on September 17-20, 1968. The book first reviews the lead sheathed cables in France and Italy, including the utilization of lead sheathed cables in Italian telephone companies; lead sheathed power cables in France; and experience of Les Cables de Lyon on lead sheathing submarine cables. The text examines the influence of lead sheath thickness on service performance of power cables. The selection takes a look at developments in the quality control of extruded lead sheath cables. The seam-failure phenomena in cable sheaths and the techniques in testing seam strength are underscored. The text also offers information on the characteristics of lead alloys for oil-filled cable sheathing; the metallurgical investigations on a Pb-Sn-Sb alloy for cable sheathing; and studies on semi-sealed lead-acid batteries. The book also discusses the chemical and other applications of lead. Increase in resistance of lead to creep stress by reaction products formed in the melt and anodic and chemical corrosion of lead base alloys in sulfuric acid solutions are discussed. The selection is a vital source of data for readers interested in the compositions, characteristics, reactions, and uses of lead.

J. E. BOWERS, in reply, said that regarding the inner profile of the barrel used in
the model screw extrusion machine it was important to note that there were
limitations imposed by the requirement that the machine should dismantle

Information Technology Research and Development

Critical Trends and Issues

Information Technology Research and Development: Critical Trends and Issues is a report of the Office of Technology Assessment of the United States Government on the research and development in the area of information technology. The report discusses information technology research and development - its goals, nature, issues, and strategies; environment and its changes; the roles of the participants; and the health of its field. The book then goes on to four selected case studies in information technology: advanced computer architecture; fiber optic communications; software engineering; and artificial intelligence. The text also talks about the effects of divestiture and deregulation on research; education and human resources for research and development; foreign information technology research and development; and technology and industry. The text is recommended for students and researchers of information technology who wish to know more about the state of research and development in this field and the applications of this research in different areas.
