The feldspars form the most abundant group of minerals in the crust of the Earth and Moon and also occur in many meteo­ rites. They playa fundamental role in all rock-forming processes at shallow depths, but are rare or absent from the upper mantle. Their detailed study is thus essential for the understan­ ding of such varied processes as magma genesis and differentia­ tion, metamorphism, al teration, erosion and sedimentation. This interest i...

Of all major branches of organic chemistry, I think none has undergone such a rapid, even explosive, development during the past twenty-five years as organic photochemistry. Prior to about 1960, photochemistry was still widely regarded as a branch of physical chemistry which might perhaps have oc­ casional applications in the generation of free radicals. Strangely enough, this attitude to the subject had developed despite such early signs of p...

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is no...

Where do you begin to look for a recent, authoritative article on the diagnosis or management ofa particular malignancy? The few general onco­ logy textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive, these are more often prelimi­ nary reports on a very limited number of patients. Certain general journals frequently publish good indepth reviews of cancer topics, and published symp...

The year is 1793, the eve of the Napoleonic Wars, and Horatio Hornblower, a seventeen-year-old boy unschooled in seafaring and the ways of seamen, is ordered to board a French merchant ship and take command of crew and cargo for the glory of England. Though not an unqualified success, this first naval adventure teaches the young midshipman enough to launch him on a series of increasingly glorious exploits. This novel-in which young Horatio get...

The Tenth International Conference on General Relativity and Gravitation (GR10) was held from July 3 to July 8, 1983, in Padova, Italy. These Conferences take place every three years, under the auspices of the International Society on General Relativity and Gravitation, with the purpose of assessing the current research in the field, critically discussing the prog­ ress made and disclosing the points of paramount im­ portance which deserve fur...

That there have been remarkable advances in the field of molecular electronic structure during the last decade is clear not only to those working in the field but also to anyone else who has used quantum chemical results to guide their own investiga­ tions. The progress in calculating the electronic structures of molecules has occurred through the truly ingenious theoretical and methodological developments that have made computationally tracta...

Modulated Structure Materials arise in two basic ways. One is through the natural tendency that certain materials have to develoo stable modulations. Tynical examples of this catenory are the lonn oeriod superlattices, the spinodal alloys and other ordered structures. Another way to introduce nodulation into a basic is throuqh our own intervention, that is ~v artificial structure techninues. Such examples as the conposition nodulated films and...

The production of rice has increased considerably in recent years due to the release of improved varieties and the adoption of better fertilization practices. Nevertheless, the production and use of inorganic N fertilizer involves costly investments in terms of energy and transport, the need for complex manufacturing plants, as well as the potential for environmental pollution. The use of agricultural systems that include dinitrogen fixing org...

At the First International Symposium on Aquatic Oligochaete Biology in Sidney, B. C. , the suggestion was made to hold the second in Pallanza, on Lake Maggiore, at the C. N. R. -Istituto Italiano di Idrobiologia. At the same time it was decided that there should be a symposium every third year. The organization of the symposium was made considerably easier by the Senior Editor's having been in personal contact with several Russian colleagues (...

The Seventeenth Jerusalem Symposium focused on dynamics on surfaces, a subject of interest in the areas of chemistry, physics and material sciences. The Symposium reflected the high standeds of these distinguished scientific meetings, which convene yearly at the Israel Academy of Sciences and Humanities to discuss a specific topic in the broad area of quantum chemistry and biochemistry. Molecule-surface dynamics constitutes a fast developing, ...

This ASI was planned to make a major contribution to the teaching of the principles and methods used in liquid phase ~esearch and to encourage the setting up of collaborative projects, as advocated by the European Molecular Liquids Group (secretary: Dr J. Yarwood, University of Durham, U. K. ). During the past five years considerable progress has been made in studying molecular liquids. The undoubted advantages of international collaboration l...

The general objective of the Tenth Canadian Fracture Conference was to respond to progress in the engineering sciences - in particular with r- pect to rapidly developing new trends in the theory and methodology of researcr and designing - and to the resulting needs of practical engineering in the specific field of fracture mechanics and related areas of engineering mechanics. The basic underlying issue is the theory and practice of physical an...

This book constitutes the edited proceedings of the Advanced Studies Institute on Boundary Element Techniques in Computer Aided Engineering held at The Institute of Computational Mechanics, Ashurst Lodge, Southampton, England, from September 19 to 30, 1984. The Institute was held under the auspices of the newly launched "Double Jump Programme" which aims to bring together academics and industrial scientists. Consequently the programme was more...
