    Since the search for hydrocarbon resources in the Arcticstarted in the 1930's the exploration activity has expandedinto many of the Arctic regions, and several of the Arcticsedimentary basins have proven to be important sources ofhydrocarbon. Nevertheless, the Arctic continental margins andadjacent onshore areas are still largely unexplored in thecontext of petroleum, and are therefore considered to be oneof the few regions in the world where significant undiscoveredsources of hydrocarbon may exist. The aim of the book is togive an updated overview of the geology of the Arcticsedimentary basins and their petroleum potential. Although thedifferent basins vary significantly as regards sedimentary fill and tectonic evolution, many of the basins share some ofthe characteristics needed to become prolific oil and gasprovinces.The book contains 45 extensively illustratedarticles. It starts with papers on the Mesozoic source rocks,and oceanic natural gas clatrates in the Arctic, respectively.Then follow articles on the regional and petroleum geology ofthe main regions; Greenland, North American Arctic, SovietArctic and the Barents Sea. Particular emphasis is placed onthe Barents Sea. The two last chapters comprise articles onsalt dynamics and methods. The book closes with a paper oninternational law in the Arctic. This volume will be ofinterest to both students and professional earthscientists/petr... explorationists working in the northernlatitudes. It will allow the readers to stay abreast of thedevelopment in this climatic region of the world.

  • Dictionary of the Printing and Allied Industries

    In English (with definitions), French, German, Dutch, Spanish and Italian
    • 2nd Edition
    • F.J.M. Wijnekus + 1 more
    • English
    The first edition of this dictionary, compiled by F.J.M. Wijnekus and published in 1967, was the result of years of systematic collection and preparation of thousands of terms and expressions which were until then not to be found in any other dictionary. The material was correlated for use in his daily work and, as the reputation of his private collection spread, there was an increasing demand for access to these findings. Until 1967 there was no comprehensive multilingual dictionary on the subject; former publications were incomplete and out of date and lacked clear definition - often leading to disastrous misunderstandings. Furthermore, the subject of printing, paper and ink technology had never been dealt with, in dictionary form, in relation to other aspects of the graphic industry.This new work, prepared by F.J.M. Wijnekus and his son, has been considerably up-dated. Much time has been devoted to checking the material against the most reliable and authoritative sources. The usefulness of the work has been further enhanced by the addition of Spanish and Italian to the original languages of English, French and German.The first edition was received with much enthusiastic praise and this new dictionary will undoubtedly continue to be an invaluable tool for all those working with the printed word in the widest sense. It is a reference work which should be in the hands of all those in any way connected with the printing industry, paper manufacturers, ink manufacturers, printers, bookbinders, publishers, lithographers, lay-out men and graphical research institutes.

  • Cyclic Deformation and Fatigue of Metals

    • 1st Edition
    • Volume 78
    • M. Bílý
    • English
    An integral review is given in this book on the fatigue phenomenon covering the fundamentals of fatigue damage initiation, relevant factors influencing fatigue crack propagation and fatigue life, random load analysis, and simulation for theoretical and experimental fatigue life assessment. The entire chain of problems related to fatigue of metals and structural components is covered. Specifically, it describes the low-cycle plastic properties and statistically interprets the material stress reaction, examining original results of investigations on inelastic deformations under high cycle cyclic loading and correlating them with a number of use parameters. The limit states of bodies with primary defects and their resistance to fatigue crack propagation are discussed. Measurements, analysis and real-time modelling of operating loads for experimental fatigue life verification are reviewed as well as introducing some new fatigue damage accumulation hypotheses based on dissipated energy. Various operating and environmental factors of the fatigue life are analyzed, including temperature, metal structures, corrosive environment, stress-strain amplitudes and their changes, random load (strain) properties, stress gradient frequency, mean level, etc. The work is intended for all those involved in research and development in the metal, machine and structure fields.

    • English
    The International Teletraffic Congress (ITC) is a recognized international organization taking part in the work of the International Telecommunications Union. The congress traditionally deals with the development of teletraffic theory and its applications to the design, planning and operation of telecommunication systems, networks and services. The contents of ITC 14 illustrate the important role of teletraffic in the current period of rapid evolution of telecommunication networks. A large number of papers address the teletraffic issues behind developments in broadband communications and ATM technology. The extension of possiblities for user mobility and personal communications together with the generalization of common channnel signalling and the provision of new intelligent network services are further extremely significant developments whose teletraffic implications are explored in a number of contributions. ITC 14 also addresses traditional teletraffic subjects, proposing enhancements to traffic engineering practices for existing circuit and packet switched telecommunications networks and making valuable original contributions to the fundamental mathematical tools on which teletraffic theory is based. The contents of these Proceedings accurately reflect the extremely wide scope of the ITC, extending from basic mathematical theory to day-to-day traffic engineering practices, and constitute the state of the art in 1994 of one of the fundamental telecommunications sciences.
