This classic work has been a unique resource for thousands of mathematicians, scientists and engineers since its first appearance in 1902. Never out of print, its continuing value lies in its thorough and exhaustive treatment of special functions of mathematical physics and the analysis of differential equations from which they emerge. The book also is of historical value as it was the first book in English to introduce the then modern methods of complex analysis. This fifth edition preserves the style and content of the original, but it has been supplemented with more recent results and references where appropriate. All the formulas have been checked and many corrections made. A complete bibliographical search has been conducted to present the references in modern form for ease of use. A new foreword by Professor S.J. Patterson sketches the circumstances of the book's genesis and explains the reasons for its longevity. A welcome addition to any mathematician's bookshelf, this will allow a whole new generation to experience the beauty contained in this text.

This study examines how two minorities - the Quaker and Anglo-Jewish communities - engaged with the sciences. With their roots in the mid-seventeenth century, both communities maintained their religious and social norms throughout the eighteenth and nineteenth centuries, while standing outside the hegemony of the Anglican Church and being subject to various forms of discrimination. Yet for both Quakers and Jews science offered educational and career opportunities and participation in the wider society. They adopted their own scientific interests, with Quakers being attracted principally to the observational sciences. Drawing on a wealth of documentary material, much of which has not been analysed by previous historians, Geoffrey Cantor charts the involvement of Quakers and Jews in many different aspects of science: scientific research, science education, science-related careers, and scientific institutions ranging from the Royal Society to the Great Exhibition."--BOOK JACKET.
A prince in one of Russia's most exalted noble families, Grigorii N. Trubetskoi was a unique and contradictory figure during World War I. A lifelong civil servant and publicist, he began his diplomatic career in Constantinople, where he served as first secretary of the embassy there for several years. He became one of the leaders of an important political orientation among the liberals that began to express opposition to the tsar, not only on questions of political freedom and domestic political reform, but also by criticizing the tsar's foreign policy on nationalistic grounds. Trubetskoi possessed significant influence over Russian foreign policy and was instrumental in pushing the regime toward an aggressive annexationist stand in the Balkans. When the Russian ambassador to Serbia died suddenly in June of 1914, Trubetskoi was appointed as his replacement—situating him at the center of Russian diplomacy during the decisive period of Russia's entry into the war. His account of this period serves as an important reference for the study of the war's outbreak. Trubetskoi also discusses how he drafted the proclamation on Poland and gives a revealing account of its origins. A valuable source on the major historical problem of the entry of Turkey into the war, the narrative provides interesting details about agreements with Britain and France. Translated by Trubetskoi's granddaughter, Elizabeth Saika-Voivod, and featuring Trubetskoi's original photographs, this fascinating memoir provides an inside look at Russian foreign policies during crucial points of the war. It will appeal to scholars, students, and general readers interested in World War I and Russian history.
Microbial physiology, biochemistry and genetics allowed the formulation of concepts that turned out to be important in the study of higher organisms. In the first section, the principles of bacterial growth are given, as well as the description of the different layers that enclose the bacterial cytoplasm, and their role in obtaining nutrients from the outside media through different permeability mechanism described in detail. A chapter is devoted to allostery and is indispensable for the comprehension of many regulatory mechanisms described throughout the book. Another section analyses the mechanisms by which cells obtain the energy necessary for their growth, glycolysis, the pentose phosphate pathway, the tricarboxylic and the anaplerotic cycles. Two chapters are devoted to classes of microorganisms rarely dealt with in textbooks, namely the Archaea, mainly the methanogenic bacteria, and the methylotrophs. Eight chapters describe the principles of the regulations at the transcriptional level, with the necessary knowledge of the machineries of transcription and translation. The next fifteen chapters deal with the biosynthesis of the cell building blocks, amino acids, purine and pyrimidine nucleotides and deoxynucleotides, water-soluble vitamins and coenzymes, isoprene and tetrapyrrole derivatives and vitamin B12. The two last chapters are devoted to the study of protein-DNA interactions and to the evolution of biosynthetic pathways. The considerable advances made in the last thirty years in the field by the introduction of gene cloning and sequencing and by the exponential development of physical methods such as X-ray crystallography or nuclear magnetic resonance have helped presenting metabolism under a multidisciplinary attractive angle.
This book, first published in the U.K. by T&T Clark, expands on the authors' prestigious Glasgow Gifford Lectures of 1995-6. Brooke and Cantor herein examine the many different ways in which the relationship between science and religion has been presented throughout history. They contend that, in fact, neither science nor religion is reducible to some timeless "essence"--and they deftly criticize the various master-narratives that have been put forward in support of such "essentialist" theses. Along the way, they repeatedly demolish the clichés so typical of popular histories of the science and religion debate, demonstrating the impossibility of reducing these debates to a single narrative, or of narrowing this relationship to a paradigm of conflict.
Informed and Healthy: Theoretical and Applied Perspectives on the Value of Information to Health Care focuses on two major issues: the value attributed to information by users and its effect on health care; and, a new model of information behavior in which the value of information drives various information activities (unlike many information models which tend to give prominence to information needs). The inductive development of the model is explained, with associated implications for theory and transferability or applicability elsewhere. The book uses a case study of the health information system in Uganda and expands the analysis by comparing it to other systems utilized by different countries in diverse levels of development. Topics such as access and use of information; value attribution and effect on health outcomes; and modelling information behavior and its implications on health informatics are discussed in detail. This book is a valuable resource for health professionals, planners, and policy makers, as well as researchers interested in health information systems and their applicability in different environments. - Provides a new model of information behaviour that emerges inductively from qualitative data - Focuses on value of information rather than information needs - Explains in detail the methodological approach used to value attribution - Serves as a valuable resource for health professionals, planners, and policy makers, as well as researchers interested in health information systems and their applicability in different environments
This handbook aims at providing a comprehensive resource on solar energy. Primarily intended to serve as a reference for scientists, students and professionals, the book, in parts, can also serve as a text for undergraduate and graduate course work on solar energy. The book begins with availability, importance and applications of solar energy, definition of sun and earth angles and classification of solar energy as thermal and photon energy. It then goes onto cover day lighting parameters, laws of thermodynamics including energy and exergy analysis, photovoltaic modules and materials, PVT collectors, and applications such as solar drying and distillation. Energy conservation by solar energy and energy matrices based on overall thermal and electrical performance of hybrid system are also discussed. Techno-economic feasibility of any energy source is the backbone of its success and hence economic analysis is covered. Some important constants, such as exercises and problems increase the utility of the book as a text.
Pure and Applied Mathematics, Volume 79: The Method of Summary Representation for Numerical Solution of Problems of Mathematical Physics presents the numerical solution of two-dimensional and three-dimensional boundary-value problems of mathematical physics. This book focuses on the second-order and fourth-order linear differential equations. Organized into two chapters, this volume begins with an overview of ordinary finite-difference equations and the general solutions of certain specific finite-difference equations. This text then examines the various methods of successive approximation that are used exclusively for solving finite-difference equations. This book discusses as well the established formula of summary representation for certain finite-difference operators that are associated with partial differential equations of mathematical physics. The final chapter deals with the formula of summary representation to enable the researcher to write the solution of the corresponding systems of linear algebraic equations in a simple form. This book is a valuable resource for mathematicians and physicists.
