Book excerpt: Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters.

Available in PDF, EPUB and Kindle. Book excerpt: An international conference. titled Nonlinear Phenomena in Chemical Dynamics was held in Bordeaux on September 7-11, 1981. The present volume contains the text of lectures and abstracts of posters presented during the meeting. This conference is part of a series of scientific multidisciplinary meetings in which chemistry is involved at various levels. Amongst the most recent ones let us mention Aachen 1979, Bielefeld 1979, New York 1979, Elmau 1981. In addition, this meeting is a direct extension of the first one that took place in Bordeaux in 1978 on the topic "Far from equilibrium: instabilities and structures," at the conclusions of which we could write (cf. Far fram Equilibrium, Springer Series in Synergetics, Vol. 3): "The three key words, far fram equilibriUm, instabilities and structuPes, best illustrate the new concepts which emerge from the description of the dynamics of various systems relevant to many different research areas. " The present proceedings show how much these remarks have remained true, even though substantial progress has been achieved during the three last years. To get a ,deeper experimental knowledge of open reacting systems, to model and simulate reaction-diffusion systems, to develop the mathematical theory of dynamical sys tems, these are the main direction~ in current investigations.

This book was released on 2012-12-06 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: With improved microscope and preparation techniques, studies of histo logical structures of plant organisms experienced a revival of interest at the end of the 19th century. From that time, histological data have sub stantially studies of the pioneers in botanical science. From the beginning of the 20th century, the microscope allowed research in cell structure, the general functional unit of living beings. Advances in cytology gradually influenced histology, at first, however, rather timidly. Only the new and spectacular progress in ultrastructural cytology and cytochemistry led to a great increase in modern work on the structures of vascular plants and the related ontogenical and physiological data, thanks to the use of the electron microscope and the contribution of molecular biology. Not only did new techniques lead to new approaches, but achieve ments in general biology shifted the orientation of research, linking in vestigation to the physiological aspects of cell and tissue differentiation. Among these, the demonstration of the general principles of develop ment, and the characterization of molecules common to plants and animals, which control and govern the main basic functions of cells and tissues, have widened the scope of modern research on plant struc tures. Present trends in biological research show that it is necessary to know the structures thoroughly, from the ultrastructural cytological scale to the scale of tissue and organ arrangement, even for physiological research on either cells, tissues, or whole organs. The study of growth factors, differ entiation, or organogenesis can be mentioned as an example.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geotectonics 8: The Structure of the Earth's Crust Based on Seismic Data covers the papers presented at an International Upper Mantle Committee (lUMC) symposium called ""Crustal Structure Based on Seismic Data"", held on July 30-31, 1971. The book focuses on the structure, composition, and characteristics of the earth's crust. The selection first offers information on the crustal structure of Central and Southeastern Europe by data of explosion seismology; structure of the earth's crust on the territory of the U.S.S.R.; and seismic studies of low-velocity layers and horizontal inhomogeneities within the crust and upper mantle on the territory of the U.S.S.R. The text also takes a look at the deep seismic investigations in the Baikal rift zone and crust of the arctic seas of Eurasia. Discussions focus on peculiarities of crustal structure, structure of the uppermost mantle, and method of investigation. The publication takes a look at the crustal structure of Japan as derived from explosion seismic data; crustal structure in the Matsushiro earthquake swarm area; and Soviet seismic studies of the earth's crust in the Pacific Ocean during the International Upper Mantle Project. The selection is a dependable source of information for readers interested in the structure of the earth's crust.

This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovative microscopic techniques, introduced during the last two decades, have contributed much to creating a new picture of the dynamic architecture of the cell, which can now be more exactly correlated with specific biochemical and physiopathological events. These developments have led to significant advances in our understanding of the physiomorphological and pathological aspects of the secretory mechanism, as well as the pharmacologic methods used to control, experimentally, the function of exocrine and endocrine glands. The integration of new ultrastructural methods such as freeze-fracture/etching, immunocytochemistry, scanning and high-voltage electron microscopy, cytoautoradiography, etc. , has proven to be of great value when applied to the study of endocrine cells and tissues. Because information on this topic has appeared in a variety of scientific and medical journals, this book: (1) reviews the results of an integrative approach presenting a comprehensive ultrastructural account of the main aspects of the field; (2) points out gaps or controversial topics in our knowledge; and (3) outlines pertinent directions for future research. The chapters, prepared by recognized authorities in the field, present traditional information on the topic in a concise manner and, with a valuable selection of original illustrations, show what the integration of new microscopic methods can contribute to the subject in terms of new concepts. This volume will be useful to cell biologists, anatomists, embryologists, histologists, pharmacologists, pathologists, and, of course, endocrinologists. It will also be of interest to students, practitioners of medicine, and to all others dealing with clinical research and diagnosis.
