Numerous spaces considered in functional analysis are also algebras, e.g. the space C (0, 1) with pointwise multiplication of functions, or the space l1 with convolution multiplication of sequences. Theorems of the general theory of Banach algebras, applied to those spaces, yield several classical results of analysis, e.g. the Wiener theorem and the Wiener-Levy theorem on trigonometric series, or theorems on the spectral theory of operators. The foundations of the theory of Banach algebras are due to Gelfand. It was his astonishingly simple proof of the Wiener theorem that first turned the attention of mathematicians to the new theory. Certain specific algebras had been studied before, e.g. algebras of endomorphisms of Banach spaces, or weak-closed subalgebras of the algebra of endomorphisms of Hilbert spaces (the so-called von Neumann algebras or Wx algebras); also certain particular results had been obtained earlier. But the first theorem of the general theory of Banach algebras was the theorem on the three possible forms of normal fields, announced by Mazur in 1938. This result, now known as the Gelfand-Mazur theorem, is the starting point of Gelfand's entire theory of Banach algebras. Mazur's original proof is included in this volume; it is its first publication. The reader of this book is supposed to have some knowledge of functional analysis, algebra, topology, analytic functions and measure theory. The book is intelligible to first year university students, though certain sections are based on material which grew beyond the usual program of university mathematics, e.g. Chapter III makes use of the theory of analytic functions of several variables. However, the necessary notions and facts are always given explicitly and provided with references. -- Contents: 1 General Information about Banach Algebras [Notation, Basic Definitions, Theorems; Topological Algebras and Banach Algebras; Examples of Banach Algebras; Methods of Construction ol Banach Algebras; Mazur-Gelfand Theorem; Some Remarks on Algebras without Unit; Group of Invertible Elements of a Banach Algebra]; 2 Commutative Banach Algebras [Multiplicative Linear Functionals; General Form of Multiplicative Linear Functionals in Specific Banach Algebras; Maximal Ideal Space; Structure Space; Spectral Norm and the Radical; Semi-simple Algebras; Topological Divisors of Zero; Shilov Boundary]; 3 Analytic Functions in Banach Algebras [Analytic Functions of One Complex Variable; Spectrum and the Joint Spectrum; Characterization of Maximal Ideals in Banach Algebras; Analytic Functions of Several Complex Variables; Decomposition of a Commutative Banach Algebra into a Direct Sum of Ideals; Locally Analytic Operations.

The book examines how ceramics can play a crucial role in achieving a high standard of living, saving energy, and protecting the natural environment. It focuses on tailoring the properties and structures of ceramics to fit specific functions in devices and equipment, along with the need for adequate processing techniques to achieve desired outcomes. Pampuch delves into the multifaceted nature of ceramics, analysing the relationships between composition, microstructure, and the unique properties these materials exhibit. The book is structured into three parts: - The Constitution of Ceramic Materials - covering crystalline states, real crystals, amorphous solids, polycrystals, multiphase materials (such as cermets and composites), fibrous ceramics, and dispersed systems; - The Properties of Ceramic Materials - addressing mechanical behaviour such as deformation, creep, and sintering processes, along with heat transfer, thermal properties, degradation in severe environments, and magnetic and electrical properties; Tables of Properties of Ceramic Materials - providing comprehensive data for ceramic materials, aiding in practical applications and research. The text explores ceramic phases, surfaces, interfaces, polycrystals, and the response of ceramics to mechanical loads, heat, and aggressive environments. Detailed discussions of topics like thermal conductivity, electrical polarisation, and optoelectronics are provided, making the book suitable for students, researchers, and professionals in materials science and engineering. Diagrams, tables, and real-world examples further enrich the content, facilitating a deeper understanding of the applications of ceramic materials in fields such as electronics, aerospace, and biomedicine. -- Contents (an introduction + suggested reading in each chapter); I.

Acoustic Properties of the Sea [Velocity & Absorption & Scattering of Sound in the Sea; Introduction to the Ray Theory of Sound Propagation in the Sea] -- In trying to discover as much as possible about the marine environment, oceanography has split into many subdisciplines, each represented by innumerable publications. To date however, there has been no concise synthesis introducing readers to the whole array of physical processes in the sea, and showing how these processes are related to one another and to other natural phenomena. The author of Marine Physics aims to fill this gap. The book presents energy and mass transfer processes in the marine environment together with an explanation of their effects on other processes. The discussions begin with physical principles and culminate in an exposition of current research problems. The volume is completed with the presentation of basic quantities, equations, formulas and diagrams, as well as indexes and 576 literature references. It should be an invaluable resource to post-graduates and scientists in the fields of engineering and oceanography, and for those interested in the protection or exploitation of the marine environment. Professor Dera leads a research team investigating the interaction of solar radiation with the constituents of the marine environment. He is the author of many papers in the field and an experienced oceanographer who has participated in many research expeditions at sea. Besides his research work, he has lectured in marine physics at Gdansk University.

It begins with an updated overview of plate tectonics, reviewing the evolution of the theory from early continental drift models to the present consensus on lithospheric plate motion, spreading, collision and subduction. Through detailed paleomagnetic data and reconstructions, the authors trace the trajectories of continents across geological time, establishing a foundation for modelling crustal deformation and intraplate stresses. A major portion of the volume is dedicated to the structure and dynamics of the mantle, with emphasis on large-scale convection. Drawing on seismic tomography and gravity field analysis, the authors differentiate upper and lower mantle processes, discuss the layered nature of mantle convection and consider the implications of these flows for surface tectonics and thermal evolution. The existence of deep mantle plumes, the potential for whole-mantle versus layered convection and the mechanical coupling between lithosphere and asthenosphere are all examined with reference to observational datasets and numerical models. Another key theme is the stress field of the lithosphere. The book analyses stress using three independent approaches: theoretical modelling based on mechanical and thermal structure; inference from surface observables such as gravity and topography; and inversion of seismic moment tensors. These methodologies converge to reveal a complex picture of stress propagation from mantle convection to crustal deformation, highlighting the interconnection of deep processes with observable tectonic phenomena like rifting, subduction and orogenic compression. Thermodynamic principles are used to address irreversible processes such as mantle differentiation, core formation and secular cooling. The authors explore how non-equilibrium thermodynamics and entropy production models can be applied to long-term geological processes, particularly to explain self-organisation, internal ordering and the emergence of structured heterogeneities in the Earth's interior. Core-mantle interactions and the role of chemical stratification in the lower mantle are also addressed through both theoretical and empirical lenses. Later chapters return to the observational record, using paleomagnetic and geomagnetic data to track Earth's field reversals, secular variation and the geodynamo process. This links outer core dynamics to observable magnetic signatures, offering a valuable window into deep-Earth processes. The study also includes comparisons with other terrestrial bodies, such as the Moon and Mars, highlighting differences in thermal history, tectonic activity and interior evolution that inform our understanding of Earth's uniqueness in the solar system. Throughout, the volume maintains a focus on integrating geophysical, thermodynamic and geochemical data with advanced computational methods. Its broad scope makes it highly relevant for geoscientists working on mantle dynamics, tectonic modelling, planetary geology and Earth system science. Appendices provide detailed data on tectonic plate motion, stress tensors, gravity anomalies and heat flow, making the work a useful reference for both researchers and graduate students. The book synthesises decades of research to offer a coherent model of the Earth's long-term evolution, linking deep interior processes with surface dynamics and planetary context.

It brings also an insight into the evolution of the planets, especially of the planetary interiors, like core formation, heat transfer and formation of minerals. Approaching different problems of the evolution of the Earth and Planets, we were forced to look upon this evolution as a part of the evolution of the Solar System, or even further as a part of the physical evolution of matter. Abundances of chemical elements can be explained only when we go back to the formation of planets and earlier to the nucleosynthesis process. In studying the formation and growth of the Earth's core, it was necessary to make a comparison with other planets, which are at different relative age of development. Two trends dominate in the research on the evolution of the Earth and the Planets. One, based on cosmology, is aimed at explaining their formation and early evolution. The other uses Plate Tectonics as a framework for describing more advanced evolutionary processes of their lithospheres and interiors. In this volume we give a cosmological insight into evolution of the Planetary System and of the Earth. The consecutive chapters present a synopsis of achievements of cosmology, a review of primordial nucleosynthesis and a discussion on formation of structures in the Universe - galaxies, stars and planetary systems, further, we present theories of planet formation and their early evolution: heat transfer, chemical and mineralogical processes, core formation and, finally, the generation of their magnetic field.

Across nine comprehensive chapters, Cymborowski blends extensive original research with critical engagement with global literature to explore the role of hormones in the life cycle of insects. The book opens with a conceptual and historical introduction to insect endocrinology, including key problems such as hormonal feedback, circadian rhythms, and molecular regulation of metamorphosis. A detailed anatomical survey follows, mapping the structure and function of the neuroendocrine system - from neurosecretory cells and corpora allata to the prothoracic glands. Chapter 3 outlines a broad range of technical approaches - including endocrine gland ablation, parabiosis, in vitro culture, autoradiography, and multiple bioassay protocols - that together provide a foundation for experimental endocrinology in invertebrate systems. Chapters 4-8 present richly detailed discussions of how specific hormones, including PTTH, juvenile hormone, ecdysone, bursicon, and others, orchestrate developmental transitions, reproductive processes, diapause, and behavioural changes. These analyses synthesise hormonal interactions within ecological and physiological contexts, highlighting the interplay between endocrine signalling and environmental factors like temperature, photoperiod, and nutrition. The final chapter turns to applied entomology, addressing the use of insect hormones and analogues as a new generation of insecticides. Cymborowski offers a prescient discussion of juvenoids, ecdysoids, and hormone inhibitors, evaluating their mechanisms of action. With its blend of classical theory, methodological rigour, and applied relevance, Insect Endocrinology continues to be a valuable resource for anyone working in invertebrate physiology, developmental biology, or integrated pest management. -- Contents [Summary & References in each chapter]: 1.

Edge-worn dust jacket shows shelfworn marks and short tears; creases on both flaps. -- The book presents applications of Mathematical Programming to non-linear static analysis of skeletal structures (trusses, frames, grillages, etc.). It is demonstrated that under the assumption of small displacements, a broad class of structural analysis problems exhibit the same internal structure. Such is the case with elastic analysis in the presence of unilateral supports or tension-only members, elastic-plastic analysis in both holonomic and non-holonomic formulations and, finally, ultimate load analysis. Throughout the book a clear and uniform methodology of presentation is used. First a complete set of governing relations is derived for a particular problem. Then that set is shown to be equivalent to a certain minimax problem (the saddle point problem), that in turn can be replaced by a pair of constrained extremum problems (dual MP-problems). Thus the complementary energy principles are established, furnishing the basis for the development of methods of numerical solution. Numerous examples illustrate the theory, while a catalog of finite elements and a collection of FORTRAN subroutines given in the Appendix allow the reader to gain his own experience in applying the proposed approach. -- Contents: Introduction; 1.

This monograph provides an extensive analysis of over 200 species of Phthiracaroidea worldwide. Niedbala's work primarily revolves around morphological features and evolutionary tendencies, applying a cladistic approach to establish a natural classification. His research is significant in the study of soil mites, particularly moss mites, and spans over 20 years. The author divides the Phthiracaroidea into two families, three subfamilies, five tribes, nine genera, and four subgenera, providing diagnoses for superior taxa and comments on synonymous genera. The book offers species inventories in two parts: the first covers 223 species personally studied by the author (with drawings and geographic distribution), while the second focuses on 116 additional species and subspecies, including uncertain forms. Niedbala also delves into neotrichy (an increase in setae or hair-like structures), zoogeography, and the ecological characteristics of the Phthiracaroidea. Keys for determining species, genera, and subgenera are provided, making this a valuable resource for taxonomists and ecologists alike. The book includes lists of species localities from various global regions, offering important data for understanding species distribution. It further highlights Professor Niedbala's role as a leading expert in the taxonomy of moss mites (Oribatida), particularly his contributions to understanding their ecological and evolutionary roles in various habitats, with special attention to arboreal mites. -- Contents: Preface; 1.
