The taboo on death is at last breaking down. There is far greater receptivity to informed discussion about death and dying. Dying with dignity is one major issue: euthanasia and the 'natural death movement' are the latest stages in a debate first stimulated by the hospice movement. Media treatment of the bereaved, especially after disasters, has attracted some adverse criticism, yet after the decline of traditional customs of mourning, people seek new models of acceptable behaviour at a time of death. The book argues that attitudes to death and to disposal are culturally formed and examines the factors in the formation and decline of such attitudes by analysing specific issues over four centuries of death.

Whatever the field of human activity-domestic or scientific, work or leisure-it is likely that some knowledge of the behaviour of electrical circuits is required to keep the processes moving, the wheels turning. In many cases, a knowledge of Ohm's law may suffice. In others, an understanding of more complex relationships may be necessary. In this book an attempt is made to provide, in a concise manner, an introduction to the main methods of treating electrical networks, whether they be carrying direct (de) or alternating (ac) electrical currents. Clearly, the range of possible circuits is vast so that the simplifications which are demonstrated in the pages that follow are of great importance to the student. However, to gain the fullest benefit from such a concise presentation, the student must devote some time to the exercises which are provided in Appendix B. The units used throughout the book are those of the International System (or SI). The various quantities which are introduced-such as current and potential and resistance-are summarized in Appendix A together with the symbols used to represent them, the unit associated with each quantity and the formula used to derive that unit from four fundamental or MKSA units.
