A basic problem for the interconnection of communications media is to design interconnection networks for specific needs. For example, to minimize delay and to maximize reliability, networks are required that have minimum diameter and maximum connectivity under certain conditions. The book provides a recent solution to this problem. The subject of all five chapters is the interconnection problem. The first two chapters deal with Cayley digraphs which are candidates for networks of maximum connectivity with given degree and number of nodes. Chapter 3 addresses Bruijn digraphs, Kautz digraphs,...

Most fluid flows of practical importance are fully three-dimensional, so the non-linear instability properties of three-dimensional flows are of particular interest. In some cases the three-dimensionality may have been caused by a finite amplitude disturbance whilst, more usually, the unperturbed state is three-dimensional. Practical applications where transition is thought to be associated with non-linearity in a three- dimensional flow arise, for example, in aerodynamics (swept wings, engine nacelles, etc.), turbines and aortic blood flow. Here inviscid cross-flow' disturbances as well as...

Many dynamical systems are described by differential equations that can be separated into one part, containing linear terms with constant coefficients, and a second part, relatively small compared with the first, containing nonlinear terms. Such a system is said to be weakly nonlinear. The small terms rendering the system nonlinear are referred to as perturbations. A weakly nonlinear system is called quasi-linear and is governed by quasi-linear differential equations. We will be interested in systems that reduce to harmonic oscillators in the absence of perturbations. This book is devoted...

The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of 13 countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France; and Zaragoza, Spain) provide postgraduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops...

For investigators engaged in the study of toxins generally, and host-specific toxins in particular, it is a rare treat to attend a meeting in which toxins involved in plant pathogenesis are emphasized. A gathering of this type provides opportunity to consider the discovery of new toxins, their chemical structures, genes encoding enzymes that control their biosyntheses, their sites of action and physiological effects on plants, and their roles (if any) in pathological processes. Having acknowledged the inspiration fostered by a 'toxin meeting', however, it is important to point out that the...

Advances in Rice Blast Research provides a complete overview of the research undertaken on the rice-blast pathosystem. This book gathers in one volume the most recent works on rice blast fungus genetics and molecular biology of pathogenicity, rice blast fungus population studies, and genetics and molecular biology of rice resistance to blast, including resistance gene cloning. It also presents the latest results on resistance breeding and resistance management strategies, epidemiology and disease management. This book is a must for plant pathologists and breeders working on...

Oral Discourse and Education examines spoken language as a field of study, looking at the various ways in which we can both theorise the place of talk in education, and examine the way talk is actually done in educational settings. Given the centrality of literacy-based practices in schools, a book focusing on talk brings quite different and important perspectives to the study of education. Talk is something that has all too often been devalued and taken for granted. What becomes evident throughout the papers included in this volume is that talk is of central importance in...

Emphasis in this second volume of Advances in Downy Mildew Research is on the biology of compatible interactions, forecasting and epidemiology, host specialisation, genetic variability amongst pathogen populations, novel methods for detection and systematics, and induced resistance. Two chapters focus on the related oomycete Albugo candida, which shares many pathogenic characteristics with the downy mildews and provides a valuable comparative pathosystem. Contributions on specific downy mildews include Bremia lactucae, Peronospora destructor, Peronospora sparsa,...

This volume addresses, specifically, priority fields of science in which joint, multidisciplinary research should be developed, encompassing rational use of natural resources and regional sustainable development, as well as the monitoring of the biosphere's ecosystem state and the risks of natural and anthropogenic hazards, and the creation of new materials and technologies. The list of priorities includes Siberia's economic, social and humanitarian problems, as well as the development of information systems for the rapid exchange of scientific data. The contributors suggest that there is a...

Members of the gastropod family Littorinidae are common throughout the world. They form a very abundant component of many intertidal and shallow subtidal ecosystems and, by their grazing, often play a central role in shaping these communities. They also display a wide range of life history strategies and many are polymorphic, making them attractive model organisms for ecologists, evolutionary biologists and physiologists alike. Areas of particular interest include ecological interactions with other animals and with algae, the effects of pollutants and the use of littorinids as sentinel...
