The community of research workers interested in solitons and signal processing came to realize that there is more to the behaviour of crystals displaying second-order nonlinearity than creating second-harmonic sources. It turns out that there are also soliton - or, more correctly, solitary wave - solutions to the coupled equations which involve a balance between the fundamental wave and the co-propagating second-harmonic wave. Second-order nonlinearity, then, is attracting a lot of interest, both in the more traditional phase-matching requirements needed to generate second-harmonic waves very efficiently - see the drive to the blue laser or its alternatives - and in the new area of solitary waves.

The validity and utility of employment tests have become entangled in the debate over the 1991 Civil Rights Bill. Worried about compliance with new federal guidelines for test validity, and concerned about possible lawsuits, the business world became wary of pre-employment testing in the early 1980s, but the use of employment testing increased throughout that decade.

Designed for daily use by professionals responsible for caring for patients with renal disease, this long-awaited primer provides a simplified, up-to-date review of peritoneal dialysis. Dealing concisely with all aspects of PD, it is written in such a style that even beginners with elementary knowledge of the subject could benefit from its use, and thus it is the perfect text for trainees or new and junior staff members. It is also an ideal text for nurses, a virtual how-to guide on PD.

Since 1975, and the identification of the solar 5-minute oscillations as global acoustic modes, helioseismology has proven to be a very active field. It enabled thorough investigation of the physical processes occurring inside the stars. In 1995, a step was achieved with the completion of the GONG network and the launch of the SoHO satellite, increasing by several order of magnitude the quality of the available data.

This book contains lectures presented by mathematicians and mathematical physicists at the NATO Advanced Research Workshop on noncompact Lie groups held in San Antonio, Texas in January 1993. It touches almost every important topic in the modern theory of representations of noncompact Lie groups and Lie algebras, Lie supergroups and Lie superalgebras, and quantum groups. It also includes several of the applications of this theory.

Complex Systems Science in Biomedicine will address the fundamentals of complex systems science, its applicability and relevance to biological and medical grand challenges and its potential for the development of novel research tools as well as innovative diagnostic and treatment strategies. This textbook focuses on the importance of complex systems science in biomedical research and its impact on clinical problem solving. In Parts I and II, the book describes general topics in complex systems science with implications for biomedicine so that the interested, non-specialist, is able to understand the underlying hypothesis as well as the approaches and techniques used in the following sections. The core of the book (Part III) features the application of the aforementioned techniques to specific biomedical topics, starting with the molecular and cellular levels, to whole organ systems (such as the brain and the immune system), leading to the description of dynamical disease processes such as cancer and aging. These examples have been chosen because of their importance and impact for the future (e.g., cancer, HIV, aging). The last part of the book (Part IV) discusses emergent technolog

This is one of two volumes which together comprise about 40 papers coming from the most outstanding contributions to the fourth European Quantum Systems in Chemistry and Physics workshop held in Marly, France, in 1999. These books cover a broad spectrum of scientific research work from quantum-mechanical many-body methods to important applications and computational developments, and from atoms and molecules to condensed matter. The first volume is subtitled Basic Problems and Model Systems, which includes the following topics: density matrices and density functionals, electron correlation effects, relativistic formulations and effects, valence theory and nuclear motion. The second volume is subtitled Advanced Problems and Complex Systems and covers the following topics: response theory, reactive collisions and chemical reactions and condensed matter.

Since 1984 and 1988, when meetings were held on the topic of primary and secondary metabolism of plant cell cultures, there has been a clear shift of the focus of ongoing research. While the cell culture itself and the production of secondary metabolites and the biosynthetic pathways and the activity of enzymes were major topics, now these aspects are linked with genes, i.e. molecular biology becomes more prominent. This book has contributions on such subjects as fermentation, enzymology of secondary metabolism, catabolism of secondary metabolites, elicitation of pathways and genetic modification of metabolic pathways. It includes contributions on the most recent achievements in the research on among other things tropane and indole alkaloids, phenolics, (iso)flavonoids, terpenes and cardenolides. It should be a useful review of the progress made in the past years and a perspective on the future developments.

Loch Lomond has long held a special place in the hearts of all the people of Scotland not only for its historic significance but also for the beauty of its countryside. Less widely known is the ecological importance of the area. It is the largest stretch of freshwater in Britain and the only loch to be crossed by the Highland Boundary Fault, one of the country's most important geological features.

The Advanced Study Institute brought together researchers in the main areas of special functions and applications to present recent developments in the theory, review the accomplishments of past decades, and chart directions for future research. Some of the topics covered are orthogonal polynomials and special functions in one and several variables, asymptotic, continued fractions, applications to number theory, combinatorics and mathematical physics, integrable systems, harmonic analysis and quantum groups, Painleve classification.

This text highlights the importance of human factors in speech technologies and presents and demonstrates the use of human factors, principles, methods, techniques, and tools in the design of speech-enabled applications. Coverage of automatic speech recognition and synthetic speech is included.

Single Photon Emission (Computer) Tomography (SPECT or SPET) is an important tool in nuclear medicine. The volume presents a basic guideline to the technology involved and discusses the application of the method to the investigation of various anatomical regions of the body.

The application of genomic markers is the mapping, diagnosis and eventual molecular cloning of loci and is of medical, biological of economic interest. The purpose of this manual is to provide new investigators in this area with an introduction and a basic practical description of how to proceed.

This work offers an outlook on the derivation and interpretation of control constructions. From data and observations, it argues that obligatory control comes in two varieties: exhaustive or partial control, the latter obtaining when PRO properly includes the controller.

Covers the areas in the physics of the solar system, with emphasis on gravitational dynamics. This work's gist is the rational, in particular mathematical, understanding of the main processes at work. It focusses on the variety of objects in the planetary system and their long-term evolution.

The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com- parative aspects of energy metabolism. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals.
