    • 1st Edition
    • Volume 43

    • English
    Piperidine, one of the simplest heterocyclic systems, is found in nature as part of several alkaloid compounds. Both natural and especially unnatural piperidine derivatives present interesting pharmacological properties. From a structural viewpoint, the conformation of piperidine has been the subject of one of the fiercest controversies in structural organic chemistry in the last few years. As a result of the combined use of several spectroscopic techniques, the conformational behavior of most types of piperidine-related compounds has been clarified. Some piperidine derivatives, namely, N-acylpiperidine, &agr;-cyanopiper... and piperidones are extremely useful and versatile intermediates in organic synthesis. The present book offers an updated and integrated view of all these topics. The aim of the book is twofold. Firstly, to reveal to the reader the combined use of different spectroscopic data, to facilitate an insight into the structure and conformational properties of any new piperidine derivative. Secondly, to establish a consistent link between conformation and reactivity for a variety of piperidine derivatives. Such a bridge is a key step for stereocontrol when dealing with the application of piperidine derivatives as synthetic intermediates. The book is conceived so that most of the information comes from visual inspection of the very abundant graphic material. An exhaustive subject index of more than 450 entries is also included.

    • English
    The use of fluidized bed coal combustion technology has been developed in the past decade in The Netherlands with a view to expanding the industrial use of coal as an energy supply. Various research groups from universities, institutes for applied science and from boiler industries participated and contributed to this research area. Comprehensive results of such recent experimentation and development work on atmospheric fluidized bed combustion of coal are covered in this volume. Each chapter, written by an expert, treats one specific subject and gives both the theoretical background as well as experimental results and verifications.Though the contents deal primarily with coal combustion, much information proved applicable and relevant for the combustion or incineration of other solid fuels and waste in a fluidized bed. Results of extended research and fundamental backgrounds are presented in order to provide the designer and operator of fluidized bed combustors with more complete and systematic information needed for an optimal design and operation. The design and operating experience of a full scale fluidized bed boiler are discussed and compared with the results of theoretical and experimental research on pilot plant scale.

  • Structure and Dynamics of Solutions

    • 1st Edition
    • Volume 79
    • Hideyuki Ohtaki + 1 more
    • English
    Recent advances in the study of structural and dynamic properties of solutions have provided a molecular picture of solute-solvent interactions. Although the study of thermodynamic as well as electronic properties of solutions have played a role in the development of research on the rate and mechanism of chemical reactions, such macroscopic and microscopic properties are insufficient for a deeper understanding of fast chemical and biological reactions. In order to fill the gap between the two extremes, it is necessary to know how molecules are arranged in solution and how they change their positions in both the short and long range. This book has been designed to meet these criteria.It is possible to develop a sound microscopic picture for reaction dynamics in solution without molecular-level knowledge of how reacting ionic or neutral species are solvated and how rapidly the molecular environment is changing with time. A variety of actual examples is given as to how and when modern molecular approaches can be used to solve specific solution problems. The following tools are discussed: x-ray and neutron diffraction, EXAFS, and XANES, molecular dynamics and Monte Carlo computer simulations, Raman, infrared, NMR, fluorescence, and photoelectron emission spectroscopic methods, conductance and viscosity measurements, high pressure techniques, and statistical mechanics methods. Static and dynamic properties of ionic solvation, molecular solvation, ion-pair formation, ligand exchange reactions, and typical organic solvents are useful for bridging the gap between classical thermodynamic studies and modern single-molecule studies in the gas phase.The book will be of interest to solution, physical, inorganic, analytical and structural chemists as well as to chemical kineticists.

  • Mechanics

    • 1st Edition
    • Volume 27
    • B. Skalmierski
    • English
    Since mechanics is the science of motion, studies in this field now cover a wider range of problems than has been the case in earlier classical approaches. This has been achieved by the inclusion of aspects relating to the mechanics of continuous media, or strength problems. The topics covered in this book present a comprehensive treatment of the subject providing a broader perspective to the meaning of mechanics, in the modern sense of the word.Problems in the areas of strength of materials, hydromechanics and theory of elasticity are examined. The author has also endeavoured to show a certain universality of some methods seemingly specific to mechanics by tackling some problems involving electrical or electromechanical systems but based on Lagrange's equations.The book has been designed to emphasize that mechanics is a deductive system, where the aim is not only to present mechanics as the science of motion but also to show that it serves as a bridge between mathematics and its applications, in the broadest sense of the word. Mechanical problems have inspired great mathematicians to come to grips with new mathematical problems, an excellent example here being the problem of the brachistochrone which initiated the development of the variational calculus. The book gives a comprehensive overview on new theoretical findings, and gives many applications which will prove indispensable to all those interested in mechanical and allied problems.

  • Probabilistic and Convex Modelling of Acoustically Excited Structures

    • 1st Edition
    • Volume 39
    • I. Elishakoff + 2 more
    • English
    This book summarises the analytical techniques for predicting the response of linear structures to noise excitations generated by large propulsion power plants. Emphasis is placed on beams and plates of both single-span and multi-span configurations, common in engineering structural systems. Since the natural frequencies and the associated normal modes play a central role in the random vibration analysis of a continuous dynamical system, rather detailed discussions are devoted to their determination. Material covered in the first chapter provides a useful reference for the subsequent discussion of multi-span structures. Also included in this volume is a hybrid probabilistic and convex-uncertainty modeling approach in which the upper and lower bounds of the cross-spectral densities of the acoustic excitation are obtained on the basis of measured data. The random vibration of a structure is treated, for the first time, as an "anti-optimization" problem of finding the least favourable value of the mean-square response.

  • Mine Openings: Stability and Support

    • 1st Edition
    • Volume 40
    • J. Aldorf + 1 more
    • English
    In this book, the authors present a review of the methods used for the solution of problems of stability and support of mine workings, based on the study and analysis of the validity conditions of individual theoretical computing procedures. The classification of these methods, based on the analysis of factors determining the behaviour of a system of mine openings, should contribute to the greater objectivity of decisions connected with the management and control of mining operations and, from the educational point of view, enable the intricate problems of stability to be better understood. Chapters dealing with support structures and technologies of support review the present state of the art with special reference to problems prevailing in Europe where mining is carried out under continuously deteriorating and less favourable natural conditions.The authors have assembled the theoretical and practical knowledge necessary for those to whom the book is addressed, namely, practising mining engineers and project managers, and students and graduates in mining colleges and schools.
