Offering an confrontation of the uncritical choice of the 'nation-state' as a unit of analysis in postwar social science, this book utilises specially collected data from 14 regions across five European states to explores how citizens define and pursue collective goals at regional scale as well as at the scale of the 'nation-state'.

A Guide to Laser Safety is a practical guide to the safe use of lasers in science, education, industry, telecommunications, medicine and entertainment. It explains the nature of laser hazards, the requirement of international safety standards and the effective implementation of safety controls. A Guide to Laser Safety is divided into three sections. Part One gives an overview of the essentials of laser safety, briefly describing the nature of laser technology, the hazards of laser radiation, the system of laser classification and general approaches to hazard control. Part Two presents the background to laser safety in greater detail, discussing laser operations, the measurement of laser emission and exposure, the biological effects of laser radiation, the management of health and safety, and the quantitative assessment of laser hazards. Part Three considers the practical implementation of laser safety in specific areas of application, covering the use of lasers in science and engineering, industrial processing, medicine, telecommunications and entertainment.

Electrical Networks focuses on the principles, methodologies, practices, and approaches involved in electrical networks, including transformers, polarity, Zobel networks, and Fourier series. The book first elaborates on d.c. currents and voltages and varying currents and voltages. Discussions focus on voltage and current sources, energy and power, voltage and current division, star-delta transformation, direction and polarity, periodical quantities, capacitors and inductors, and energy stored in capacitors and inductors. The manuscript then takes a look at some properties of networks and magnetic coupled inductors. Topics include equivalent circuits for magnetic coupled coils, voltage and the current transformer, mutual induction, impedance transformation, current direction, voltage polarity and the mode of winding, polar diagrams, resonance, and Zobel networks. The publication examines networks containing switches, complex frequency, and Fourier series. Considerations include frequency spectrum, finite Fourier series, capacitor discharges over a resistor, natural oscillations, and discontinuity. The monograph is a valuable source of information for electricians and researchers interested in electrical networks.
