This COSPAR Colloquium Series deals with the main achievements that were accomplished through the collaborative efforts among ISTP participants; the plasma dynamics of magnetic reconnection in a thin plasma sheet, the action of the solar wind on the plasma population in the plasma sheet and around the magnetotail boundary layer, the relationship between the substrom expansion region and the X-line formation in the magnetotail, and the temporal evolution of the dipolarization from from the near-Earth to the distant tail.

Pushed out of her village, Sage's only option is to begin the grueling trek to the city, a place so evil in her imagination that she might be better off if she didn't make it. The dangers she faces and the challenges she must meet on her trek are only the beginning of the much greater journey she has begun, carried on the sound of the hooves of the Plainsrunner.

The 6th ESLAB Symposium, organised by the Space Science Department (formerly ESLAB) of the European Space Research and Technology Center, was held in Noord wijk from 26-29 September 1972. This year the theme was "Photon and Particle Interactions with Surfaces in Space". More than 60 scientists attended mainly from ESRO Member States and from America. The first part of the Symposium was devoted to introductory lectures and to papers on interactions with spacecraft. The second half dealt with the photon and particle interactions with celestial objects, and ended with a general discussion and presenta tions of areas where new developments are required. The purpose of this Symposium was to throw light on the importance of the prob lems which are evoked by E. A. Trendelenburg in his introductory remarks, and to sum up our present understanding of these phenomena. It is hoped that this book will prove useful to physicists and engineers who are actually involved in space ex periments and are concerned with interactions of these types. R. J. L. GRARD OPENING ADDRESS Gentlemen, I should like to welcome you to the 6th ESLAB Symposium. In the past we have always organised this Symposium jointly with our sister in stitute, ESRIN, in Frascati, but unfortunately reductions in the scientific budget have forced ESRO to terminate the activities of that laboratory. Nevertheless, we have decided to carryon the tradition, and we shall continue on our own organising this series of symposia on specialised subjects.

The pile construction technologies are considered in the context of the compact urban development in case of new construction and reconstruction. Their advantages and disadvantages are set forth. The pile pe-netration technology using the jacking-down method is discussed. Special consideration is given to the modern technology of constructing replacement and displacement piles. Besides, screw steel piles are discussed that recently have been brought into active use in production and civil con-struction including the construction of foundations for country and low-rise houses. The last chapter is dedicated to the quality control of piling works. The Appendices to this Manual include the technical features of rigs and accessories for the penetration of driven, jacked, screw, replacement and displacement piles. This Manual is intended for the students of civil construction institu-tions of higher education who study building disciplines, students of up-grading qualification institutes and engineers and technicians who specialize in geotechnical engineering.

The magnetosphere is the region where cosmic rays and the solar wind interact with the Earth's magnetic field, creating such phenomena as the northern lights and other aurorae. The configuration and dynamics of the magnetosphere are of interest to planetary physicists, geophysicists, plasma astrophysicists, and to scientists planning space missions. The circulation of solar wind plasma in the magnetosphere and substorms have long been used as the principle paradigms for studying this vital region. Charles F. Kennel, a leading scientist in the field, here presents a synthesis of the convection and substorm literatures, and an analysis of convection and substorm interactions; he also suggests that the currently accepted steady reconnection model may be advantageously replaced by a model of multiple tail reconnection events, in which many mutually interdependent reconnections occur. Written in an accessible, non-mathematical style, this book introduces the reader to the exciting discoveries in this fast-growing field.
