The peristence of European unemployment stands in striking contrast to the cyclical pattern of unemployment in the US. Many people attribute the rise in European unemployment to increased imbalances between the pattern of labour demand and supply - in other words, to greater mismatch, but existing mismatch indicators do not support this view. However, the obvious inference is not legitimate because the evidence is based on trended data, and th...

In this book we present the main results on the asymptotic theory of ordinary linear differential equations and systems where there is a small parameter in the higher derivatives. We are concerned with the behaviour of solutions with respect to the parameter and for large values of the independent variable. The literature on this question is considerable and widely dispersed, but the methods of proofs are sufficiently similar for this material...

Advanced composite materials have been a major research focus for the past forty years. As a reinforcement for conventional materials including glass, ceramics and polymers, carbon has proved to be the most successful. Carbon gives these materials flexibility so that they may be produced in bulk form with a wide variety of properties. Whereas carbon/carbon composites are the most effective materials in extreme temperature conditions. Applicati...

, h In the XIX century, mathematical physics continued to be the main source of new partial differential equations and ofproblems involving them. The study ofLaplace's equation and ofthe wave equation had assumed a more systematic nature. In the beginning of the century, Fourier added the heat equation to the aforementioned two. Marvellous progress in obtaining precise solution repre­ sentation formulas is connected with Poisson, who obtained ...

The emergence and spectacularly rapid evolution of the field of atomic and molecular clusters are among the most exciting developments in the recent his­ tory of natural sciences. The field of clusters expands into the traditional disci­ plines of physics, chemistry, materials science, and biology, yet in many respects it forms a cognition areaofits own. The identifying attributes ofthis area reflect the specificity ofthe objects, subjects, pr...

As the regional models required to understand and control the generation, distribution and deposition of air pollutants become more precise, the need to understand the detailed effects of hilly and mountainous terrain becomes more acute. The Alpine regions and the mountainous Mediterranean coasts have large effets on the way the pollutant burden is spread in their areas. Similarly an understanding of the effects of chemical and physical proces...

Forty chapters deal with various aspects of tissue culture, in vitro manipulation, and other biotechnological approaches to the improvement of maize. They are arranged in eight sections: - In Vitro Technology, Callus Cultures and Regeneration of Plants, Somatic Embryogenesis. - Wide Hybridization, Embryo, Ovule, and Inflorescence Culture, in Vitro Fertilization. - Production of Haploids and Double Haploids, Anther and Pollen Culture. - Protop...

Like the previous nine volumes published between 1988 and 1996, Medicinal and Aromatic Plants X is unique in its approach. It comprises 22 chapters dealing with the distribution, importance, conventional propagation, micropropagation, tissue culture studies, and the in vitro production of important medicinal and pharmaceutical compounds in various species of Actinidia, Alkanna, Arnebia, Campanula, Catharanthus, Centella, Chenopodium, Cornus, C...

This book is motivated largely by a desire to solve shape optimization prob­ lems that arise in applications, particularly in structural mechanics and in the optimal control of distributed parameter systems. Many such problems can be formulated as the minimization of functionals defined over a class of admissible domains. Shape optimization is quite indispensable in the design and construction of industrial structures. For example, aircraft an...

Glaucoma Update VI comprises the latest progress in scientific glaucomatology. Forty-one articles of highly reputed experts in the field cover the genetics and other risk factors of the disease and provide new insights into the pathophysiology of blood flow, visual function and optic neuropathy in glaucoma. Special emphasis is placed on innovative treatment options, both medical and surgical.

Hadron colliders probe physics at new energy frontiers and search for new particles and forces. In addition, hadron colliders now provide also an environment for precision physics. The present volume collects the results from recently completed runs at major colliders as well as new ideas about collider physics and techniques. It will serve as the main source of reference in the field for many years to come.

approaches to the experimental problems that still face us in understanding this most fascinating of organs. Too many people contributed to the completion of this volume to allow acknowledg­ ment of all the individual efforts, but we particularly thank the reviewers whose input into the editorial process was invaluable and the authors of these chapters who revised their text, sometimes more than once, to bring it to the high standards set by t...

This book represents the first European effort to provide a collection of test descriptions used in evaluation of the compatibility of biomaterials in contact with tissues and blood. The urge to compile this book arose from the fact that it is the properties of the material which ultimatively seem to determine the functional outcome of a medical device, almost regardless of how ingenious the construction of the very device is. The longer the e...

Dem Werkzeugbau kommt in der Industrie als Schnittstelle von Organisation und Technologie eine Schlüsselstellung zu. Verursacht durch den wachsenden Wettbewerbsdruck gewinnt eine Steigerung der Wettbewerbsfähigkeit auch in diesem Bereich zunehmend an Bedeutung. Vor diesem Hintergrund wird in dem vorliegenden Buch eine Vielzahl von "Best-Practice"-Lösungen für die organisatorische und technologische Gestaltung im Werkzeugbau vorgestellt. Von be...

In the summer of 1999, an international group of experts convened in Jerusalem, Israel, in order to define the major environmental challenges facing humanity at the dawn of the new millennium and - where possible - propose ways of addressing them. Almost 50 selected articles are collected in the present book, which constitutes a striking interdisciplinary combination of state-of-the-art science with the latest views on environmental law, educa...

Cardiovascular disease affects 20% of all Americans and is the leading cause of death in the USA. Every year approximately 1, 500.000 Americans suffer from an acute myocardial infarction, and over 25% of the total number of deaths in this country are attributable to coronary artery disease. Unstable angina causes over 650, 000 hospital admissions, and in the absence of medical therapy, the rate of progression from unstable angina to infarction...

The concept of macroscopic waves and patterns developing from chemical reaction coupling with diffusion was presented, apparently for the first time, at the Main Meeting of the Deutsche Bunsengesellschaft fur Angewandte Physikalische Chemie, held in Dresden, Germany from May 21 to 24, 1906. Robert Luther, Director of the Physical Chemistry Laboratory in Leipzig, read his paper on the discovery and analysis of propagating reaction-diffusion fro...

It is a truism that turbulence is an unsolved problem, whether in scientific, engin­ eering or geophysical terms. It is strange that this remains largely the case even though we now know how to solve directly, with the help of sufficiently large and powerful computers, accurate approximations to the equations that govern tur­ bulent flows. The problem lies not with our numerical approximations but with the size of the computational task and th...

The pilot boat just moved away and'its lights are already fading towards the coast of Northeastern Queensland over which Saturn is going to set. There is still quite some time to go before dawn. The big ship has now regained her cruise speed following its roughly northwesterly route in the South Coral Sea along the chain of nearby reefs. Few people are around at this time, except a dozen early birds sharing some 'shipshaping' exercise on the t...

Fahreigenschaften und Fahrleistungen eines Automobils werden massgeblich von der Aerodynamik geprägt, ebenso aber auch der Komfort seiner Insassen und die Funktion seiner Aggregate. Die fahrzeug-Aerodynamik ist vorwiegend empirischer Natur und interdisziplinär. Daran orientiert sich dieses Buch. Wo immer möglich, werden aus dem Erfahrungsschatz der Autoren allgemeingültige Aussagen über strömungsmechanische Phänomene abgeleitet und Auswirkunge...
