The nature of time has long puzzled physicists and philosophers. Time potentially has very fundamental yet unknown properties. In 1993 a new model of multi-dimensional time was found to relate closely to properties of the cosmological redshift. An international conference was subsequently convened in April 1996 to examine past, current and new concepts of time as they relate to physics and cosmology. These proceedings incorporate 34 reviews an...

This is the first publication of the 170 letters written by the Abbé Dominique Chaix to Dr. Dominique Villars between 1772 and 1799, when they were collaborating on the publication of the first flora for the old province of Dauphiné. The letters reveal the uncertainties of plant classification in the late 18th century, but, more generally, the penetration of the Enlightenment into a remote, alpine region of France. Both botanists were of recen...

A logically organized advanced textbook, which turns the reader into an active participant by asking questions, hinting, giving direct recommendations, comparing different methods, and discussing "pessimistic" and "optimistic" approaches to numerical analysis. Advanced students and graduate students majoring in computer science, physics and mathematics will find this book helpful.

A survey of recent developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. Current national R&D, plans are summarized. The actinide-fuelled critical reactors are associated with control problems, since they tend to have a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. Current thinking is turning to accelerator-driven subc...

The contributions to this book are based on our current knowledge of solar corona physics and on the prospects for future total eclipse observations, focusing on the eclipse of August 11, 1999 - the last this century - which forecasters believe will occur at precisely the maximum of solar activity. The results of past eclipse observations are reviewed, including coronal hot and cold structures, coronal heating, public education and instrumenta...

The volume presents an overview of recent developments in the thermal management of electronic systems. This is increasingly recognised as an important factor in current design methodology. The topics covered include thermal management in general, analytical and computational thermal modelling, thermal characterisation of components, single and multiphase convective cooling, measurement techniques, thermomechanical modelling and thermally indu...

Americanist Culture History reprints thirty-nine classic works of Americanist archaeological literature published between 1907 and 1971. The articles, in which the key concepts and analytical techniques of culture history were first defined and discussed, are reprinted, with original pagination and references, to enhance the use of this collection as a research and teaching resource. The editors also include an introduction that summarizes the...

In 1992 a Concerted Action Programme (CAP) was initiated by Peter Sijmons with the purpose of intensifying collaborations between 16 European laboratories working on plant-parasitic nematodes. The four-year programme entitled `Resistance mechanisms against plant-parasitic nematodes' focused on molecular aspects of the interaction between sedentary nematodes and plants on the model system Arabidopsis and on novel resistance strategies. Funding ...

This book is divided into three parts. In the first part, Action, are collected papers that concern the formal theory of action, the logic of norms, and the theory of rational decision. The papers in the second part, Belief Change, concern the theory of belief dynamics. The third part, Cognition, concerns Fitch's knowability paradox as well as problems concerning the graphic representation of information.

This Symposium on fundamental stellar properties was held to honour Emeritus Professor Robert Hanbury Brown on the occasion of his 80th birthday. The speakers described recent advances in interferometry, astrometry, spectroscopy and in theoretical models of stellar atmospheres and interiors. The emphasis was on the critical assessment of the quality, accuracy, and prospects for improvement of the observational data and theoretical models, on t...
