Book excerpt: Tunnelling has become a fragmented process, excessively influenced by lawyers'notions of confrontational contractual bases. This prevents the pooling of skills, essential to the achievement of the promoters' objectives. Tunnelling: Management by Design seeks the reversal of this trend. After a brief historical treatment of selected developments, th

Download or read book Quantum Tunnelling in Enzyme catalysed Reactions written by Rudolf K. Allemann and published by Royal Society of Chemistry. This book was released on 2009 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been an explosion in knowledge and research associated with the field of enzyme catalysis and H-tunneling. Rich in its breath and depth, this introduction to modern theories and methods of study is suitable for experienced researchers those new to the subject. Edited by two leading experts, and bringing together the foremost practitioners in the field, this up-to-date account of a rapidly developing field sits at the interface between biology, chemistry and physics. It covers computational, kinetic and structural analysis of tunnelling and the synergy in combining these methods (with a major focus on H-tunneling reactions in enzyme systems). The book starts with a brief overview of proton and electron transfer history by Nobel Laureate, Rudolph A. Marcus. The reader is then guided through chapters covering almost every aspect of reactions in enzyme catalysis ranging from descriptions of the relevant quantum theory and quantum/classical theoretical methodology to the description of experimental results. The theoretical interpretation of these large systems includes both quantum mechanical and statistical mechanical computations, as well as simple more approximate models. Most of the chapters focus on enzymatic catalysis of hydride, proton and H" transfer, an example of the latter being proton coupled electron transfer. There is also a chapter on electron transfer in proteins. This is timely since the theoretical framework developed fifty years ago for treating electron transfers has now been adapted to H-transfers and electron transfers in proteins. Accessible in style, this book is suitable for a wide audience but will be particularly useful to advanced level undergraduates, postgraduates and early postdoctoral workers.

Download or read book Tunnelling and Negative Resistance Phenomena in Semiconductors written by D. K. Roy and published by Elsevier. This book was released on 2014-05-09 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tunnelling and Negative Resistance Phenomena in Semiconductors presents a critical review of tunneling theory and shows how this leads to the negative resistance phenomena in pn junctions. The physics, technology, and circuitry of semiconductor negative resistance devices are surveyed. The book challenges the conventional assumptions of tunneling theory and proposes an alternative approach that allows the possibility of a change in energy during tunneling. It also introduces the reader to the manufacture, operation, and applications of semiconductor negative resistance devices. Comprised of five chapters, this volume begins by presenting a logical physical interpretation of the wavefunction with its so-called ill-behaved nature and considering other consequences of the energy distribution effect. The next chapter is devoted to the tunneling effect through tunnel diodes along with other properties of this device. The circuitry and technology of tunnel diodes as well as backward and Zener diodes are then examined, along with negative conductance devices that are used as microwave sources. The final chapter is concerned with negative conductance switching devices. This book is intended for students and practitioners in the fields of physics and electronics.

Download or read book Tunnelling 94 written by Vidar Aarvold and published by Springer. This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now more than twenty years since a proposal was first mooted to hold an international tunnelling symposium in Britain. At the time of the first symposium, held in London in 1976, the Channel Tunnel pro ject had just been shelved. Last weekend a charity walk was held in the finished tunnel, which will be open for business later in the year. Tunnels have figured prominently, and at times spectacularly, in the development of national and international links and it is hoped that such links gather pace in the future. It is particularly pleasing that Alastair Biggart of Storebrelt has agreed to deliver the twenty-sixth Sir Julius Wernher Memorial Lecture of the Institution of Mining and Metallurgy, entitled 'The changing face of tunnelling', at the start of this event. * Although almost every edition of the technical journals on tunnelling reports another £1 billion scheme somewhere in the world, it would be unfair of me to suggest that tunnelling is restricted to these prestigious schemes for major transport links. Much of the work that makes mod ern life possible receives hardly a mention outside the technical press and one suspects that society at large applies the 'out of sight, out of mind' attitude even more readily to underground construction than it does to other forms of engineering. Clearly, there is a contiiming need to improve the capacity and performance of our infrastructure, while hav ing a careful regard for the environment.

Download or read book Quantum Tunnelling in Condensed Media written by Yu. Kagan and published by Elsevier. This book was released on 2012-12-02 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essays in this book deal with of the problem of quantum tunnelling and related behavior of a microscopic or macroscopic system, which interacts strongly with an "environment" - this being some form of condensed matter. The "system" in question need not be physically distinct from its environment, but could, for example, be one particular degree of freedom on which attention is focussed, as in the case of the Josephson junction studied in several of the papers. This general problem has been studied in many hundreds, if not thousands, of articles in the literature, in contexts as diverse as biophysics and quantum cosmology. The editors have grouped together papers which are representative of the main trends in this area in the last fifteen years or so and sufficiently related in general spirit and terminology that common themes can be discerned. The contributions are primarily theoretical, but the comparison with experiment is discussed wherever possible.

Download or read book Tunnel Boring Machines Trends in Design and Construction of Mechanical Tunnelling written by A. Schulter and published by CRC Press. This book was released on 2020-08-26 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past ten years there was a worldwide trend towards increased use of Tunnel Boring Machines (TBM's). This trend covers a broad variety of applications ranging both from small diameters for sewers and other utilities to large diameters for double track railway and even three-lane highway tunnels. The response to this has been the development of both hard rock machines in the direction for application in soft ground, and soft ground TBM's to be used in soft rock. Parallel to the technical development of TBM's towards applications for longer tunnels, running through changing geological conditions, there are needs for the development of lining methods. 'TBM Tunnel Trends' an international lecture serie collection, aims to present the latest scientific and practical state of the art of TBM tunnelling, taking into consideration interactions between machinery and lining. 26 international highly recognized papers.

Download or read book Building Response to Tunnelling written by Construction Industry Research and Information Association and published by Thomas Telford. This book was released on 2001 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to predict the potential damage to buildings accurately and to have confidence in the chosen protective measures is of increasing importance for the viability of urban tunnelling. The Jubilee Line Extension Project (JLEP) presented a unique opportunity to capture reliable field measurements of the effects of tunnelling on a wide range of buildings. Building response to tunnelling: Case studies from the Jubilee Line Extension, London is the result of this work. Volume 1 describes the relevant part of the JLEP, the methods of settlement prediction and building damage assessment used on the project, and the objectives of the research. Further chapters provide accounts of the geology and historical development of more of the case study buildings (between Green Park and Canada Water stations of the JLE route). Full transcriptions are included of the before-the-event and independent best practice predictions of surface and at-depth ground movements at two greenfield sites and the settlement of four buildings, which were made specially for the research. The concluding chapter of Volume 1, written by Professor John Burland, presents the overall findings of the research to date. Volume 2 presents, in their geographical sequence, the twenty-seven case studies; from Green Park in the west to London Bridge, and then eastward to Canada Water station. These case studies include two instrumented greenfield sites and several examples of prestigious buildings in London's west end that were protected by compensation grouting. The case studies present descriptions of the buildings, the works that affected them and measurements made to record their response. This valuable and informative two volume book has been written by the experts who participated in the research and is generously illustrated with numerous line drawings, graphs, pictures and maps. Building response to tunnelling: Case studies from the jubilee Line Extension, London will be essential reading to tunnelling and geotechnical engineers and all those who have an interest in this successful and interesting underground project.
