This item is printed on demand - it takes 3-4 days longer - Neuware -The increasing scale and intensity of modern blast-furnace operation, combined with a simultaneous reduction in coke rate, have led to more stringent coke quality requirements with a greater emphasis on the coke's (1 2) role as a burden spacer ' - Accordingly, coke quality data limited to chemical composition, initial size grading and ambient size stability are insufficient to predict the coke's behaviour in use. A realistic assess ment of the likely performance of coke should also take into consideration its resistance to degradation in the chemical and thermal environment of the blast furnace. A test is, therefore, needed which simulates as far as possible the mechanical, chemical and thermal conditions of the smelting process and measures the resultant changes in size distribution of the coke, and hence in its bulk permeability to gas flow, using representative samples of the feed coke as charged to the furnace. Moreover, new developments in coke production make it necessary to reassess coke testing so as to guide the coke producer in making the best use of available coals. The mode of mechanical coke breakage at ambient temperature has been extensively characterised and related to changes in the coke's bulk permeability(3). In contrast, the causes of deterioration in the hot strength and size of bulk coke arising from its partial gasification with carbon dioxide and reheating to high temperature are relatively less explored. The present paper describes the v. 352 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From the beginning, the systems research movement has shown a high potential for offering a conceptual framework for the understanding of social systems. Much of this potential has been realized, but a major gap remains with regard to operational investigative aids. Developments of the last ten years with a method ological orientation and emphasis seem finally to be filling this gap. The purpose of this book is to describe the most advanced of these developments and to make them available to a wider audience. The emphasis is on developments that are primarily oriented toward interaction with expertise in the social sciences and that thus hold the most promise for social systems investigation. In particu lar, attempts have been made to provide substantiation and illustration of three main points: (1) the common motivation and essential integrability that systems research provides for developments and considerations along a very broad spec trum of interests; (2) the very diverse nature of the types and forms of considera tions that may be meaningfully integrated; and (3) the operational and usable nature that developments in systems methodology represent for research in the social sciences. The book is divided into three parts with a generally increasing degree of specificity. The first part (Chapters 1, 2, and 3) deals with foundational issues associated with modeling and methodology as areas worthy of study in their ix X PREFACE own right. 208 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The thrust here is for those who want to know more than the answer to an exam question - an approach to disease diagnosis and treatment which emphasizes thoughtful consideration of alternatives, finding ones way through uncertainties and lack of knowledge. The annual seminar on which this volume is based has evolved into a forum for open discussion of puzzling questions - actually old questions in the light of new data. To me, the adventure of life is in recognizing the openendedness of all things. So you thought that a certain disease was a settled question In medicine a 'settled' question is a transient conclusion. Even the solutions to the so-called simplest problems have another side. Our aim this year was to air out concepts and conclusions about hypertension, fluid-electrolytes, and tubulopathies. The stars were Drs. Juan Rodriguez-Soriano, Alan Gruskin, and Donald Potter, along with Drs. Gustavo Gordillo, Ronald Kallen, and Antonia Novello as guest faculty. Local stars included Drs. Mary Jane Jesse, Jacques Bourgoignie, and Carlos Vaamonde. Their contributions added to those of the other faculty and registrants, coalesced into vibrant exchanges which are reproduced here for the reader's perusal. 292 pp. Englisch.

Au cours des recherches effectuees a partir de cette nouvelle technique il s'est tres vite avere que le champ d'applications etait 3 considerable et qu'il fallait completement reviser certaines theories anterieures. Avec des observations au niveau de quelques centimetres 3 il n'est plus possible d'etudier des phenomenes isolement et3 quel que soit le pole d'interet fixe il est necessaire aussi d'etudier 3 conjointement les autres aspects du systeme. Tres vite3 il est alors apparu que les recherches potentielles relatives a ce type d'observa tions ne se bornaient pas seulement aux applications lunaires mais pouvaient recouvrir un domaine plus vaste en Astronomie Geodesie 3 3 Geophysique Cosmologie etc . . . C'est ainsi qu'est ne le programme 3 3 international EROLD avec comme but plus specifique l'etude de la 3 rotation terrestre mais avec des aspects connexes lies en particulier 3 a la dynamique du systeme Terre-Lune dans son ensemble. Il etait alors naturel de faire le bilan a un niveau eleve de ces annees de recher 3 3 ches dans cette nouvelle phase de la connaissance. Par ailleurs d)autres types de techniques modernes ont egale 3 ment vu le jour durant cette derniere decennie avec entre autres 3 applications la determination de la rotation de la Terre. 378 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Modern philosophy has benefited immensely from the intelligence and sensitivity, the creative and critical energies, and the lucidity of Polish scholars. Their investigations into the logical and methodological founda tions of mathematics, the physical and biological sciences, ethics and esthetics, psychology, linguistics, economics and jurisprudence, and the social sciences - all are marked by profound and imaginative work. To the centers of empiricist philosophy of science in Vienna, Berlin and Cambridge during the first half of this century, one always added the great school of analytic and methodological studies in Warsaw and Lw6w. To the world centers of Marxist theoretical practice in Berlin, Moscow, Paris, Rome and elsewhere, one must add the Poland of the same era, from Ludwig Krzywicki (1859-1941) onward. (From our preface to Wiatr [1979p. Other movements also have been distinctive in Poland. Phenomenology was developed in the impressive school of Roman Ingarden at Cracow, semiotics from the early work of the philosopher and psychologist Kazimierz Twardowski at Lw6w in the 1890's, with masterful develop ment by his disciples Kotarbinski and Ajdukiewicz onward, conceptual foundations of physics in the incisive methodological reflections of Marian Smoluchowski, and mathematical logic from Jan I:.ukasiewicz and Stanislaw Lesniewski to Tarski, Mostowski, and many others. 520 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The design of asynchronous circuits is increasingly important in solving problems such as complexity management, modularity, power consumption and clock distribution in large digital integrated circuits. Since the second half of the 1980s asynchronous circuits have been the subject of a great deal of research following a period of relative oblivion. The lack of interest in asynchronous techniques was motivated by the progressive shift towards synchronous design techniques that had much more structure and were much easier to verify and synthesize. System design requirements made it impossible to totally eliminate the use of asynchronous circuits. Given the objective difficulty encountered by designers, the asynchronous components of electronic systems, such as interfaces, became a serious bottleneck in the design process. The use of new models and some theoretical breakthroughs made it possible to develop asynchronous design techniques that were reliable and effective. Algorithms for Synthesis and Testing of Asynchronous Circuits describes a variety of mathematical models and of algorithms that form the backbone and the body of a new design methodology for asynchronous design. The book is intended for asynchronous hardware designers, for computer-aided tool experts, and for digital designers interested in exploring the possibility of designing asynchronous circuits. It requires a solid mathematical background in discrete event systems and algorithms. While the book has not been written as a textbook, it could nevertheless be used as a reference book in an advanced course in logic synthesis or asynchronous design. Algorithms for Synthesis and Testing of Asynchronous Circuits also includes an extensive literature review, which summarizes and compares classical papers from the 1960s with the most recent developments in the areas of asynchronous circuit design testing and verification. The validity and utility of employment tests have become entangled in the debate over the 1991 Civil Rights Bill. Worried about compliance with new federal guidelines for test validity, and concerned about possible lawsuits, the business world became wary of pre-employment testing in the early 1980s, but the use of employment testing increased throughout that decade. 480 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Weeds are a fascinating study for specialists, not only because of their economic importance, but also since in this case biology must be combined with history and agriculture (and its economic aspects). Thus, weed scientists may be concerned with pure basic research, concentrating on general aspects, or with applied science, i.e. having a practical orientation. One of the aims of this book is to create a synthesis between these two branches of study and to review the literature of both fields. The agrestals, the weeds of arable land ~ the most important group from an economic point of view ~ was chasen as the main topic. Other weed groups could only be mentioned briefly (e.g. grassland weeds), or superficially (e.g. aquatic weeds), or had to be omitted completely (e.g. ruderals, because they are so heterogeneous), to keep this volume to an acceptable size and price. Nevertheless, nearly all subsections of botanical science have been treated. 472 pp. Englisch.
