New Approaches In Geomagnetism And The Earth S Rotation

The rotation of the Earth and its relation to geomagnetism are topics that have been under debate for more than a century. In this volume both of these phenomena are discussed in the light of new approaches. Keith Runcorn presents a survey of the papers and concluding remarks. F Richard Stephenson gives a thorough review of the history of the Earth's rotation whilst Stig Flodmark finds an explanation for the Chandler wobbles and the drift of the polar axis. A New Approach to Polar Motion by Losito et al. gives another view of the same theory. The fascinating idea of a single-crystal inner core is discussed by Flodmark and Weber and magnetic rigidity in the Earth is a new concept dealt with by Mörner. The mechanisms behind magnetic reversals, ice ages and earthquakes are other subjects under debate. It is hoped that the present volume will encourage forthcoming debates on these subjects.

Containing the proceedings of the tenth International Conference on Advances in Fluid Mechanics it follows the success of all previous conferences in the series, the first of which took place in 1996. The field of fluid mechanics is vast and has numerous, diverse applications. This book covers a wide range of topics, including basic formulations and their computer modelling as well as the relationship between experimental and analytical results. The emphasis is on new applications and research currently in progress. Topics covered include: Computational methods; Hydrodynamics; Fluid structure interaction; Multiphase flow; Bio-fluids; Electronic components; Environmental fluid mechanics; Heat and mass transfer; Industrial applications; Energy systems; Nano and micro fluids; Turbulent flow; River hydraulics; Combustion problems; Jets; Fluidics; Bubble and drop dynamics.

Classically orbital cycles have been recognized in pelagic and lacustrine sequences characterized by quiet sedimentation, not disturbed by tectonics. Hoiwever, there is now increasing recognition that orbital cycles do influence climate and oceanography in general terms. There is also increasing acceptance of the possibility at least that the effect should be felt over large parts of the Earth's surface and that orbital cycles may well leave signs in other sedimentary environments that are commonly considered to be dominated by tectonics and eustasy. Containing thirty-one papers from a symposium held at the International Sedimentological Congress in Nottingham in 1990, this volume spans a range of topics from the astronomical theory behind orbital forcing, to field studies dealing with a broad range of sedimentary environments, and to modelling and simulation. State-of-the-art research papers. International expert authorship. The latest research in the highly topical subject of orbital forcing.

Temperature and precipitation increase and decrease because of natural causes. However, anthropogenic changes, such as an enhanced greenhouse effect, may result in alterations in the regional climate and in relative sea level. Serious changes in climate and sea level-with adverse effects particularly along low-lying coasts-would affect millions of people. Climate Change takes an in-depth, worldwide look at coastal habitation with respect to these natural and anthropogenic changes. No universally applicable coastal model can be used to describe climatic changes. This unique book provides individual discussions of beaches and barrier islands, cliffs, deltas, tidal flats and wetlands, reefs, and atolls. The impact of climatic change on coastal ecology and agriculture is investigated, and human responses to the effects of climatic change along the world's coasts are included.

The NATO ASI held in the Geophysical Institute, University of Alaska Fairbanks, June 17-28, 1991 was, we believe, the first attempt to bring together geoscientists from all the disciplines related to the solar system where fluid flow is a fundamental phenomenon. The various aspects of flow discussed at the meeting ranged from the flow of ice in glaciers, through motion of the solar wind, to the effects of flow in the Earth's mantle as seen in surface phenomena. A major connecting theme is the role played by convection. For a previous attempt to review the various ways in which convection plays an important role in natural phenomena one must go back to an early comprehensive study by 1. Wasiutynski in "Astro physica Norvegica" vo1. 4, 1946. This work, little known now perhaps, was a pioneering study. In understanding the evolution of bodies of the solar system, from accretion to present-day processes, ranging from interplanetary plasma to fluid cores, the understanding of flow hydrodynamics is essentia1. From the large scale in planetary atmospheres to geological processes, such as those seen in magma chambers on the Earth, one is dealing with thermal or chemical convection. Count Rumford, the founder of the Royal Institution, studied thermal convection experimentally and realized its practical importance in domestic contexts.

This volume provides an updated understanding of the progress and current problems in the interplay between fundamental physics, astrophysics and cosmology.In the last years, the cross section between these fields has been increasing, both at the theoretical and experimental levels: particle physics experiments, astronomical observations, space satellite data. Such interplay has fruitfully influenced research activity setting up Astrofundamental physics.Topics covered in this volume are: early universe, large scale structure of the universe, dark matter problem, cosmic microwave background radiation, gravitational wave astronomy and neutrino astrophysics. The inter-relation between these topics is important and a source of problems at the frontiers of present knowledge and experimental limits. Latest available data are constraining theory and models in these topics. The book reviews achievements, confronts theory and models with observations and provides information on the latest developments and discussions on future prospects.It also includes a section on stellar spectroscopy and spectrophotometry which covers Daniel Chalonge's work as well as present progress and future prospects in these fields.
