Directional Solidification of Steel Castings
1st Edition
R. Wlodawer
English
Directional Solidification of Steel Castings summarizes the results of a large number of investigations, mostly scientific in character, on the directional solidification of steel castings. The influence of design on the technical possibilities of producing casting in the foundry is examined. Diagrams, simple basic rules, and formulae are provided, along with many practical examples. This book is comprised of 16 chapters and begins with an introduction to the technical and psychological aspects of steel casting before turning to a discussion of the influence of shape and dimensions on the time it takes for castings to solidify. The thermal gradient, feeder heads, and cavities in steel castings are then considered. In particular, the effect of the thermal gradient on solidification and feeding range are examined. Methods for increasing the thermal gradient in the casting are described, including the use of mold heating pads, breaker cores or Washburn cores; external cooling (iron chills); cooling fins; internal chills; and exothermic pads. Cavities in steel castings which are commonly mistaken for true shrinkage cavities are also analyzed. This monograph is particularly suitable for foundry managers, foremen, technicians, casting designers, and students.
The Mechanical Behaviour of Engineering Materials

1st Edition

English
The Mechanical Behaviour of Engineering Materials aims to relate properties and structure, and to provide a theoretical basis upon which to extrapolate when conditions or materials outside previous experience arise. The present text refers primarily to metals and alloys, other (non-crystalline) solids are treated rather less fully. This is largely dictated by the state of knowledge at the present time, for although there is a large mass of data concerning the properties of non-metallic materials, much of this is empirical and a full explanation is made difficult by the complexities of an irregular initial structure. The book can be divided into the three sections covering constitution, properties, and significance of test data. Separate chapters discuss properties such as heterogeneity, elasticity, plasticity, and fracture. Subsequent chapters deal with tensile and hardness tests; creep, fatigue and impact tests; and the selection of engineering materials. Throughout the text the author has endeavored to confine the discussion to those aspects of materials science which appear to be reasonably well understood at the present time.

English
Man and His Environment, Volume 2 covers the proceedings of the Second International Banff Conference of Man and His Environment, held in Banff Springs Hotel, Alberta, Canada on May 19-22, 1974. The conference addresses the broad environmental issues in relation to man and his natural environment. This book is organized into six sessions encompassing 17 chapters. The first session deals with the continuing development of the Canadian mineral resources and the role of the National Energy Board in the country's energy management. This session also provides an overview of the world hydrocarbon energy resources. The second session discusses various problems in overpopulated and industrially and technologically underdeveloped countries and developments in the environmental restraints on production practices to protect the environment. The subsequent two sessions look into the effects of human activities on his environment. Topics covered in these sessions include the use and misuse of technology; social, economic, and political impact of urbanization; and government environmental policies. The concluding sessions outline the ethical structure of Western Society and the development of a theoretical model of public morality. These topics are followed by discussions on the essential nature of the environmental problems and the systematic relations between the Western culture and Western environment.

These topics are followed by a discussion on the application of chemical shift to organic compound analysis and the principles of the spin-spin coupling .The final chapter considers the applications of time- dependent phenomena in NMR spectroscopy. This book will prove useful to analytical chemists and researchers in the allied fields.
Disaster Technology
An Annotated Bibliography
1st Edition
Diana H. Manning
English
Disaster Technology: An Annotated Bibliography presents an annotated bibliography of disaster technology. The references are arranged in the following sections: relief organization, medical aspects (planning, general, nutrition), sociological aspects, and physical aspects (general, earthquakes). The abstracts are arranged alphabetically by author's name in each section. Some of the controversial issues and the areas related to disaster technology are reviewed. This volume consists of seven chapters, the first of which introduces the reader to general aspects of relief work especially international disaster aid. Logistic, administrative, political, and economic factors are highlighted. The next three chapters deal with medical aspects of relief work and cover hospital disaster planning and surgical triage, medical problems arising from disasters, and nutritional problems of relevance to development as well as to disasters. Attention then turns to sociological studies of disasters that have been carried out in industrialized societies in general and America in particular. Some work on psychological and psychiatric factors is considered. The chapters on physical aspects of disaster relief includes literature on public health engineering, design for disaster (including emergency shelter), and prevention and warning techniques. Earthquakes are considered separately in the final chapter. This book is written to supply relief agencies with information on the published and unpublished literature available concerning technical aspects of disaster relief and prevention with special emphasis on developing countries. It is also intended to provide those involved in relevant research with information on disaster topics from other disciplines.
Elements of Theoretical Mechanics for Electronic Engineers

1st Edition
Franz Bultot
English
Elements of Theoretical Mechanics for Electronic Engineers deals with theoretical mechanics, which is considered one of the fundamental branches of instruction essential to training an engineer. This book discusses the oscillatory motions and their counterparts in electrical circuits and radio, and provides an introduction to differential operators of vector field theory. Other topics covered include systems and functions of vectors; dynamics of a free point; vibrations and waves; and statics. Worked examples and many notes on the application of most sections of the theories to electrical developments are also provided in this text. This publication is valuable to students taking a Higher National Diploma or Diploma in Technology, as well as students in the final year of the Higher National Certificate in electrical engineering.

A Course of Mathematics for Engineers and Scientists, Volume 5 presents the solutions of differential equations by obtaining the results in different forms. This book discusses the significant branch of mathematics generalizing the elementary ideas of function, integration, and differentiation. Organized into four chapters, this volume begins with an overview of the use of Fourier series that leads to solutions consisting of infinite series. This text then discusses the fundamental advantage of Laplace and Fourier transformation. Other chapters consider the technique of obtaining the solutions of ordinary, and several partial, differential equations from definite integrals. This book discusses as well the mathematical basis underlying the transformation methods connecting Laplace and Fourier transformations, which is given by the advancement of complex variable theory. The final chapter deals with the series of devices for inverting the transformation functions. This book is a valuable resource for scientists, engineers, mathematicians, and undergraduate students.
