      The properties of materials at high temperature play a vital role in their processing and practical use. The real properties of materials at elevated temperatures are very often governed by defects in their structure. Lattice defects may consist of point defects like vacancies, interstitial atoms or substituted atoms. These classes are discussed in general and specifically for oxides, nitrides, carbides and sulfides. Defect aggregates, shear structures and adaptive structures are also described. Special attention is paid to hydrogen defects which seem to play an important role in several materials.Defects in solids lead to transport properties such as diffusion and conductivity. These themes are thoroughly treated in this book, with examples from various materials being provided. Special attention is paid to the transport properties of grain boundaries. In high temperature corrosion and other types of oxidation, the diffusion of atoms through the reaction products is often the rate limiting step of the reaction. This book takes the reader from the theoretical treatment of defects to applications in high temperature corrosion. Reactions between metals and pure oxygen lead to the formation of oxides on the surface, and the reaction rates may often be related to the diffusion coefficients of the oxide. However, in practical use alloys are subjected to other severe gaseous atmospheres which may often lead to accelerated attack on the material. The severest condition, namely where a salt deposit is combined with oxidizing gases, is called hot corrosion. This and other types of corrosion are also covered. Finally, a chapter is devoted to the prevention of corrosive attack on materials by the addition of rare earth metals.The book has been published in honour of Professor Per Kofstad on the occasion of his 60th birthday. Professor Kofstad has for many years been active in the field of high temperature chemistry in all its aspects, from basic and theoretical work to its application in high temperature corrosion of metals and alloys. The various chapters have been contributed by his friends and colleagues, all of whom are international experts in the field.

      Engineering Design contains papers given during the Summer School of Engineering Design held at the University of Nottingham, 21-24 September 1964. The School consisted of 18 lectures spread over four days. Design covers a vast range of subject matter for which only years of college and industrial training and experience can provide adequate equipment. In the 18 lectures, the lecturers attempted to highlight the important factors within their varied experience. The backcloth to design, covering company organization, planning, programming of design and development, were elaborated in the opening lectures. Another lecture summarized ideas on company design procedures; stressed the importance of always attempting to predict results in terms of numbers; and demonstrated how to develop a freedom of manipulating numbers, even when knowledge of rigorous mathematical processes is limited. Other lectures covered organization and design for mass production; the increasing importance of powder metallurgy as a manufacturing method; properties of materials; important aspects of the use of computers in design; and the design of major engineering projects: diesel engines, aircraft engines, and high-speed packaging machines.

      Biological Phosphate Removal from Wastewaters contains the proceedings of an International Association on Water Pollution Research and Control Specialized Conference held in Rome, Italy on September 28-30, 1987. Contributors review advances that have been made in the removal of biological phosphates from wastewaters, both at the fundamental scientific level and in the practical application of the process. Topics range from the fundamental microbiology and biochemistry of the enhanced biological removal of phosphate to the practical full-scale plant experiences with phosphorus removal and sludge handling from such processes. This text is comprised of 43 chapters; the first of which describes the utilization of polyphosphate as an energy reserve in Acinetobacter sp. and activated sludge. Attention then turns to metabolic control in polyphosphate-accumu... bacteria and its role in enhancing biological phosphate removal. The biochemistry and energetics of biological phosphorus removal are also considered. The next section is devoted to process modeling and includes chapters that explore the kinetics of biological excess phosphorus removal; factors affecting anaerobic stabilization during biological phosphorus removal; and the behavior of magnesium in biological phosphate removal. In the next section, bench/pilot-scale studies are presented; one of which investigated the reduction of returned phosphorus from a sludge treatment process. The book concludes with a discussion on phosphate removal mechanisms and pilot- and full-scale experiences. This book will be of interest to students, practitioners, and policymakers in water pollution control.

      These Proceedings consider all aspects of the environmental problems facing the world today - scientific, social, economic, philosophical and historical. Many of the discussions which followed paper presentations are included in the text. Along with scientific discussions of solutions to particular problems, the book argues for a new approach to thought and action in the use of natural resources. If a constructive global strategy towards the protection of the environment is to be socially compatible and economically sound, then it must be developed through an interdisciplinary approach which will avoid the impractical solutions which might be suggested by theoretical or unilateral considerations. Ecological, economic, social and cultural research must be accompanied by the development of a new mentality of respect for the environment which will inculcate a reasonable and moderate use of natural resources.

      Sources of Ignition: Flammability Characteristics of Chemicals and Products describes the flammability characteristics of substances and deals with the different sources of ignition. Case histories are presented for review and analysis. The book is comprised of six chapters and seven appendices. The introduction gives a basic description of the anatomy of fire and explosions, including the access to fuel and the interaction of oxygen and fuel. A description of the flammable limits of gases, dusts, mists, and mixtures and the method of estimating these follow. The text also explains the flash point of a substance and the method of calculating it, using citations from Fuji and Hermann. The ignition energy of a chemical, as well as how to estimate it using the method of Calcote et al., is also presented. The book explains that autoignition temperature of gases is dependent on different factors, such as time delay, oxygen concentration, and catalyst effects of materials, but may still be estimated citing Zabetakis, 1965 as reference. The formula is given in more detail. Finally, the energy sources for ignition are enumerated as mechanical, electrical, thermal, and chemical. The appendices deal with chemicals, self-heating substances, organic peroxides, substances prone to spontaneous combustions, unstable substances, flammability characteristics of dusts, and a checklist of possible sources of ignition. This book is beneficial to fire safety engineers, firemen, fire prevention maintenance administrators, fire hazard officers, and other personnel whose line of work is in fire safety and prevention.
