The Viruses: Catalogue, Characterization, and Classification (The Viruses)

by Heinz Fraenkel-Conrat

During the past two decades, virus taxonomy has advanced to the point where most viruses can be classified as belonging to families, genera, or groups of related viruses. Virus classification is primarily based on chem­ ical and physical similarities, such as the size and shape of the virion, the nature of the genomic nucleic acid, the number and function of com­ ponent proteins, the presence of lipids and of additional structural fea­ tures, such as envelopes, and serological interrelationships. The families, genera, or groups of viruses that have been defined on the basis of such criteria by the International Committee on Taxonomy of Viruses (ICTV) will be described in some detail in this catalogue and illustrated by elec­ tron micrographs. In my present attempt to list most if not all well es­ tablished and studied viruses in alphabetical order, I have largely confined myself to identifying them only in such taxonomic terms, generally without quoting specific data reported for individual viruses. If the latter data do not at times agree closely with those given for the taxon or group, it is difficult to decide to what extent this is attributable to misclassi­ fication due to insufficient data and errors in the analytical procedures and descriptions, or to what extent this is an expression of Nature's free­ dom of choice and abhorrence of restrictive classifications.

Vision in Vertebrates

by M. A. Ali

When Dr. Katherine Tansley's "Vision in Vertebrates" appeared in 1965, it filled a real void that had hitherto existed. It did so by serving at once as a text-book: for an undergraduate course, a general introduction to the subject for post-graduate students embarking on research on some aspect of vision, and the interested non-specialists. Gordon Walls' "The Vertebrate Eye and It. s Adaptive Radiation" and A. Rochon-Duvigneaud's "Les Yeux et la Vision des Vertebres" have served as important sources of information on the subject and continue to do so even though it is 40 years since they appeared. However, they are essentially specialised reference works and are not easily accessible to boot. The genius of Katherine Tansley was to present in a succinct (132 pages) and lucid way a clear and an interesting survey of the matter. Everyone liked it, particularly the students because one could read it quickly and understand it. Thus, when it seemed that a new edition was desirable, especially in view of the enormous strides made and the vast literature that had accumulated in the past 20 years, one of us (MAA) asked Dr. Tansley if she would undertake the task. Since she is in retirement and her health not in a very satisfactory state both she and her son, John Lythgoe (himself a specialist of vision), asked us to take over the task.

The Vitamins: Their Role in Medical Practice

by J. Marks

This book has been designed, as its title implies, as a practical book for medical practitioners, although it should be of interest to medical students and nutritionists. It attempts to provide essential information about this important group of substances rather than be an all embracing monograph on the subject. For this reason biochemical and physiological considera­ tions have been kept to a minimum, and aspects of animal disorders and animal husbandry have not been considered. The material is often presented in a rather dogmatic fashion and, with rare exceptions, references are not included since this makes reading more difficult. The exceptions, where references are provided, are the therapeutic claims, and the series of recent studies which have indicated that vitamin deficiencies are still widely present among certain groups of the population of many industrially developed countries. To add to this reference list there is a reading list which has been selected to give key books, reviews with extensive bibliography and important articles over the past 10 years. From this reading list it is possible to trace most of the literature on the vitamins since they were first described over half a century ago.

Walking Machines: An Introduction to Legged Robots (Chapman and Hall Advanced Industrial Technology Series)

by D. J. Todd

The first chapter of this book traces the history of the development of walking machines from the original ideas of man-amplifiers and military rough-ground transport to today's diverse academic and industrial research and development projects. It concludes with a brief account of research on other unusual methods of locomotion. The heart of the book is the next three chapters on the theory and engineering of legged robots. Chapter 2 presents the basics of land loco­ motion, going on to consider the energetics of legged movement and the description and classification of gaits. Chapter 3, dealing with the mechanics of legged vehicles, goes into leg number and arrangement, and discusses mechanical design and actuation methods. Chapter 4 deals with analysis and control, describing the aims of control theory and the methods of modelling and control which have been used for both highly dynamic robots and multi-legged machines. Having dealt with the theory of control it is necessary to discuss the computing system on which control is to be implemented. This is done in Chapter 5, which covers architectures, sensing, algorithms and pro­ gramming languages. Chapter 6 brings together the threads of the theory and engineering discussed in earlier chapters and summarizes the current walking machine research projects. Finally, the applications, both actual and potential, of legged locomotion are described. Introduction Research into legged machines is expanding rapidly. There are several reasons why this is happening at this particular time.

Walking On Glass

by Iain Banks

Her eyes were black, wide as though with some sustained surprise, the skin from their outer corners to her small ears taut. Her lips were pale, and nearly too full for her small mouth, like something bled but bruised. He had never seen anyone or anything quite so beautiful in his life.'Graham Park is in love. But Sara Fitch is an enigma to him, a creature of almost perverse mystery. Steven Grout is paranoid - and with justice. He knows that They are out to get him. They are. Quiss, insecure in his fabulous if ramshackle castle, is forced to play interminable impossible games. The solution to the oldest of all paradoxical riddles will release him. But he must find an answer before he knows the question.Park, Grout, Quiss - no trio could be further apart. But their separate courses are set for collision.

Water and Ions in Biological Systems

by Alberte Pullman V. Vasilescu L. Packer

As the First International Conference on Water and Ions in Biological Systems (Bucharest, June 25-27, 1980) was appreciated as a success, a second one was organized in the fall of the year 1982 under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Romanian Academy of Medical Sciences, the Romanian Biophysical Society (Union of Societies for Medical Sciences in the Socialist Republic of Romania) and in co­ operation with the International Union for Pure and Applied Bio­ physics (IUPAB). The responsibility for the scientific program and organization of the Second Conference on Water fell on an International Scientific Committee which included Prof. J. Tigyi (Pees), President of the UNESCO Expert Committee on Biophysics, Prof. K. Wuthrich, Secretary General of IUPAB and Prof. H. Eisenberg, (member of the IUPAB Council) under the guidance of an Executive Board whose members were Prof. J. Jaz (representative of UNESCO), Prof. B. Pullman (Vice­ President of IUPAB) and Prof. V. Vasilescu (President of the Romanian Biophysical Society). The Meeting was attended by more than 250 specialists including 150 Romanian participants and others from Bulgaria, Czechoslovakia, England, the Federal Republic of Germany, the German Democratic Republic, Greece, Hungary, India, Israel, Italy, Japan, the Netherlands, Nigeria, Poland, Sweden, Switzerland, USSR, USA, Venezuela, Yugoslavia. The proceedings of the Conference took place in the Medical Faculty of Bucharest. The theoretical and practical importance of the Meeting was pointed out by the speakers, among whom were Prof.

Water Quality Management: A Review of the Development and Application of Mathematical Models (Lecture Notes in Engineering #11)

by M.B. Beck

During 1978-1982 the International Institute for Applied Systems Analysis (IIASA) was responsible for a research project on Environmental Quality Control and Management. The project was begun under the direction of Professor O. F. Vasiliev (from the Institute of Hydrodynamics of the Siberian Branch of the USSR Academy of Sciences) and was subsequently led by myself. This review is very much a re'fiection of that IIASA project. The major themes of the IIASA project were: (i) research into the methodological aspects of modeling river and lake sys­ tems [some of the principal results of this research appear in M. B. Beck and G. van Straten (eds. ) (1983), Uncertainty and Forecasting of Water Quality (Springer, Berlin (West)), and in K. Fedra (1983), Environmental Modeling Under Uncertainty: Monte Carlo Simulation (IIASA Research Report RR-83-28)]; (ii) case studies in the application of mathematical models to lake eutrophi­ cation control [results of which are summarized in L. Somlyody, S. Hero­ dek, and J. Fischer (eds. ) (1983), Eutrophication of Shallow Lakes: Model­ ing and Management (The Lake Balaton Case Study) (IIASA Collaborative Proceedings CP-83-S3), and in K. Fedra (1983), A Modular Approach to Comprehensive System Simulation: A Case Study of Lakes and Watersheds (in W. K. Lauenroth, G. V. Skogerboe, and M. Flug (eds. ), Analysis of Ecological Systems: State-of-the-Art in Ecological Modelling, pp. 195-204. Elsevier, Amsterdam)]; iv (iii) a policy study of operational water qua,lity management [M. B. Beck (1981), Operational Water Quality Management: Beyond Planning and Design (IIASA Executive Report ER-7)].

Water Waves and Ship Hydrodynamics: An Introduction (Mechanics of Fluids and Transport Processes #5)

by R. Timman A.J. Hermans G.C. Hsiao

In the spring of 1971, Reinier Tirnrnan visited the University of Delaware during which time he gave a series of lectures on water waves from which these notes grew. Those of us privi­ leged to be present during that time will never forget the experience. Rein Tirnrnan is not easily forgotten. His seemingly inexhaustible energy completely overwhelmed us. Who could forget the numbing effect of a succession of long wine filled evenings of lively conversation on literature, politics, education, you name it, followed early the next day by the appearance of the apparently totally refreshed red haired giant eager to discuss our mathematical problems with keen insight en remarkable understanding, ready to lecture on fluid mechanics or optimal control theory or a host of other subjects and ready to work into the evening until the cycle repeated. He thought faster, he knew more, he drank more and he slept less than any of us mortals and he literally wore us out. What a rare privilege indeed to have participated in this intellectual orgy. Tirnrnan's lively interest in almost every­ thing coupled with his buoyant enthusiasm and infectious op­ timism epitomized his approach to life. No delicate nibbling at the fringes, he wanted every morsel of every course. In these times of narrow specialization truly renaissance figures are, if not extinct, at least a highly endangered species. But Tirnrnan was one of that rare breed.
