This IUTAM Symposium was the first international conference on asymptotic methods for turbulent shear flows. It was the aim of this Symposium to bring together the experts and research workers to discuss recent work in this field. There was general consensus among the participants of the Symposium, that the asymptotic methods provide powerful tool for turbulence modelling, which ought to be used more intensively in practice in addition to the numerical meth ods. This was the Scientific Committee: K. Gersten (Germany, Chairman) A. Kluwick (Austria) J. - P. Guiraud (France) F. T. Smith (United...

This book is a collection of papers presented at the international symposium on forest sector analysis held in Miyazaki, Japan, in 1998. It is structured with three themes: understanding global forest sector issues, discussing the contribution of modeling efforts to forest sector analysis, and discussing the role of Japanese forest policy in a global sense. The most important features are the case studies using various types of forest sector models. From a modeling perspective, changes in modeling efforts include more detail of spatial and multiple market levels, intergenerational welfare...

The quality of human life has been maintained and enhanced for generations by the use of trees and their products. In recent years, ever rising human population growth has put a tremendous pressure on trees and tree products; growing awareness of the potential of previously unexploited tree resources; and environmental pollution have both accelerated the development of new technologies for tree propagation, breeding and improvement. Biotechnology of trees may be the answer to solve the problems which can not be solved by conventional breeding methods. The combination of biotechnology and...

This book volume has been divided into three sections and contains a total of 23 chapters. Section A contains eleven chapters covering topics such as studies of embryo development and cell biology of white spruce, proliferative somatic embryogenesis in woody species, somatic embryo germination and desiccation tolerance in conifers, performance of conifer somatic seedlings, apoptosis during early somatic embryogenesis, water relation parameters in conifer embryos, image analysis of somatic embryos, somatic embryogenesis in woody legumes, cold storage and crypreservation, and commercialization...

Providing a unique, state-of-the-art review of both traditional and emerging themes in the economics of natural forest disturbances, this book shows how neo-classical economic principles can be integrated with ecosystem analysis and modern econometric methods to uncover the causes and consequences of natural forest disturbances.

Accurate assessment of environmental hazards and related risks is a primary prerequisite for effective environmental health protection, at both the individual and collective level. National and regional policies on environmental health need to be guided by knowledge about the risks to the populations involved; as the Environmental Action Plan for Europe notes, 'priority setting requires the comparative assessment of risks to health of different environmental factors against the cost of controlling them.' In recent years this has assumed particular importance, for with the encouragement of the...

The research that has culminated in the pUblication being introduced . worldwide) save by one or two of this Manual was in the first place undertaken private conifer enthusiasts. My own efforts at 1 for a new edition of the book Manual of Cultivated recording data at Devizes made possible the Conifers by P. den Ouden and Dr B. K. Boom appearance in 1979 of a larger book: Manual of (both now deceased), published in 1965. Dwarf Conifers. That book was clearly in effect The claim in that book to have included every a partial up-dating of the den Ouden and Boom cultivar published since 1753 was...

World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world's supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees....
