Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -MBRl'OLOGl' studies the succession of transformations undergone by the fertilized E egg in the formation of a new individual. Development of the embryo is directed by morphogenetic mechanisms ruled by a strict chronology. Survival of the egg, its -transport in the genital tract, and the adaptation of the maternal organism to its presence are controlled by hormonal actions. Knowledge of these subjects is proving to be increasingly important for the medical practitioner. Such information helps to explain anatomic correlations; organ relation ships also illuminate the etiology of numerous pathologic conditions. Disturbances of prenatal development engender congenital malformations and constitute an important cause of perinatal mortality and postnatal morbidity. We are gratef'ul to numerous student.~ and colleagues whose cooperation has aided preparation of this book. THE AUTHORS. TRANSLATOR'S PREFACE Translation of this work was undertaken in order to make available in English this excellent and unusual aid for the teaching arid study of mammalian, primarily human, embryology. This hook emphasizes visual presentations. It combines the use of exceptionally clear and instructive drawings with photomicrographs and concise but complete text 111 an exposition of the dynamic aspects of development. Thus, the three volumes of this book will be of help in preparation and review for students, research workers, medical practitioners such as obstetricians and pedia tricians, and-others who are concerned with embryology. Analysis of the precise timing of various stages of human development makes it especially useful for all who are interested in the study and prevention of congenital malformations. 168 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This monograph is a revised set of notes on recent applications of the theory of cones, arising from lectures I gave during my stay at the Centre de recherches mathematiques in Montreal. It consists of three chapters. The first describes the basic theory. The second is devoted to applications to mathematical programming and the third to matrix theory. The second and third chapters are independent. Natural links between them, such as mathematical programming over matrix cones, are only mentioned in passing. The choice of applications described in this paper is a reflection of my p«r9onal interests, for examples, the complementarity problem and iterative methods for singular systems. The paper definitely does not contain all the applications which fit its title. The same remark holds for the list of references. Proofs are omitted or sketched briefly unless they are very simple. However, I have tried to include proofs of results which are not widely available, e.g. results in preprints or reports, and proofs, based on the theory of cones, of classical theorems. This monograph benefited from helpful discussions with professors Abrams, Barker, Cottle, Fan, Plemmons, Schneider, Taussky and Varga.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 108 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The human face is invariably interesting, even as an object of embryologic analysis. The early embryonic growth processes are located around the developing sense organs, among which the nose holds a key position. The first indication of the development of the nose is the formation of the placodes, oval areas of thick ened and condensed ectoderm, one on each side of the head. Each of these placodes is transformed, via the nasal groove, into the nasal tube, sometimes indicated as primitive nasal cavity. In the literature this transformation has been described as an isolated process that changes the superficial facial region. Some authors, including Wolgensinger (1950), think that the active component of this trans formation primarily is the ectoderm of the nasal placode. Others, i. e. Hochstetter (1891), Kallius (1905) and Vermeij-Keers (1967), assume this component be located in the mesenchyme. Peter (1913, 1949), Patten (1953, 1961), Warbrick (1960), and Andersen and Matthiessen (1967) hold both these components to be active. In the first and last of these three concepts the ectoderm of the nasal placode and the nasal groove respectively, is thought to invade the mesenchyme in the posterior direction. Invading ectoderm has also been considered to form - independent of the transformation - the organ of Jacobson and the naso lacrimal duct and to separate the conchae (e. g. Born, 1876; Legal, 1883; Kallius, 1905; Peter, 1913, 1949; Streeter, 1948; Andersen and Matthiessen, 1967). 32 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -If one takes the intuitive point of view that a system is a black box whose inputs and outputs are time functions or time series it is natural to adopt an operator theoretic approach to the stUdy of such systems. Here the black box is modeled by an operator which maps an input time function into an output time function. Such an approach yields a unification of the continuous (time function) and discrete (time series) theories and simultaneously allows one to formulate a single theory which is valid for time-variable distributed and nonlinear systems. Surprisingly, however, the great potential for such an approach has only recently been realized. Early attempts to apply classical operator theory typically having failed when optimal controllers proved to be non-causal, feedback systems unstable or coupling networks non-lossless. Moreover, attempts to circumvent these difficulties by adding causality or stability constraints to the problems failed when it was realized that these time based concepts were undefined and; in fact, undefinable; in the Hilbert and Banach spaces of classical operator theory. 284 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The rather excessive public preoccupation of the immediate past with what has been labeled the 'environmental crisis' is now fortunately being replaced by a more sus tained and rational concern with pollution problems by public administrators, engineers, and scientists. It is to be expected that members of the engineering profes sion will in the future widely be called upon to design disposal systems for gaseous and liquid wastes which meet strict pollution control regulations and to advise on possible improvements to existing systems of this kind. The engineering decisions involved will have to be based on reasonably accurate quantitative predictions of the effects of pollutants introduced into the atmosphere, ocean, lakes and rivers. A key input for such calculations comes from the theory of turbulent diffusion, which enables the prediction of the concentrations in which pollutants may be found in the neighborhood of a release duct, such as a chimney or a sewage outfall. Indeed the role of diffusion theory in pollution prediction may be likened to the role of applied mechanics (,strength of materials') in the design of structures for adequate strength. At least a certain group of engineers will have to be proficient in applying this particular branch of science to practical problems. At present, training in the theory of turbulent diffusion is available only at the gra duate level and then only in a very few places. 264 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume is intended to give an overall picture of research in pro gress in the field of generative grammar in various parts of Europe. The term 'generative grammar' must, however, be understood here rather broadly. What seemed to be an easily definable technical term several years ago is becoming more and more vague and imprecise. Research in generative gram mar is carried on according to rather diversified methodological principles and being a generative grammarian is often more a matter of confession than any adherence to the common line of methodology which can be traced back to the conception of grammatical description initiated by Noam Chomsky. The direct or indirect influence of this conception is, however, clearly recog nizable in most of the papers of this volume. The most difficult thing was, naturally enough, to select appropriate papers in the realm of semantics. Apart from the special trend in generative grammar referred to as 'generative semantics' (though here, too, we might ponder on what 'generative' really means) the term 'generative' is hardly employed in semantics. The search for semantic primes, the application of the methods of mathematical logic, the inquiry into the intricate relationships between syntax and semantics and the utilization of syntactic information in semantics are perhaps the most charac teristic traits of contemporary semantics. All of this, of course, is at no variance with the principles of generative grammar, on the contrary, most of it has been made possible through the achievements of generative grammar. 704 pp. Englisch.…
