The field of rheology of foods is extensive and a researcher in the field is called upon to interact with a diverse group of scientists and engineers.  In arranging this symposium for the AIChE meeting in Chicago in November 1990 the papers were carefully selected to highlight this diversity.  All but two of the chapters in this book are based on papers which were presented at this symposium, the additional paper was presented at the Conference on Food Engineering, Chicago, March 1991, and the book opens with an introductory overview.  All the papers are peerreviewed research contributions.  The chapters cover a range of applications of food rheology to such areas as food texture, stability, and processing.  This volume will be a reference source for workers within this wide and varied field.

As LANs have proliferated, new technologies and system concepts have come to the fore. One of the key issues is how to interconnect networks. One means of interconnection is to use a 'bridge'. Other competing technologies are repeaters, routers, and gateways. Bridges permit traffic isolation, connect network segments together and operate at the MAC layer. Further, because they operate at the MAC layer, they can handle a variety of protocols such as TCP/IP, SNA, and X.25.

This report focuses on the specific technology of bridging two networks and the competing approaches of spanning tree [backed by DEC] and the source route technology [backed by IBM]. Both of these approaches are compared and their strengths and weaknesses described and contrasted. Other approaches that combine the two approaches as well as novel approaches to this problem are described.

In a world of increasing complexity of networks, it is imperative that the user understand the possible means of bridging two networks and the capabilities of the various vendors products. The report focuses itself on developing that critical understanding.

Non-sag (NS) tungsten is a dispersion-strengthened microalloy with elemental potassium, which is contained as microscopic bubbles in the tungsten lattice. Under working conditions in an incandescent lamp the potassium is a gas under high pressure. These gas bubbles essentially prevent the recrystallization of the tungsten wire and are responsible for the outstanding creep resistance of NS tungsten at the extremely high temperatures of a glowing lamp filament. More than 90% of NS tungsten is used for incandescent lamps. In addition, small amounts are used as defroster heating wires in automobile windshields and as heating wire coils for aluminium evaporation in metallization applications.<p>The presented papers deal with the chemical reactions and the chemical compounds occurring along the path from tungsten raw materials to the final NS tungsten filament; a compendium of present knowledge on the different chemical aspects of NS tungsten manufacture is presented. It is composed of nine individual papers, each of them written by experts working in the field.

Making maps dates back at least four thousand years and it is widely recognised that many maps are of great historical value and present a skilled method of summarising the real world on a sheet of paper. Less well known is the judgement involved in the selection and simplification of features, the complex transformation of space and the exacting standards which are needed in cartography.  This book is primarily a tribute to Professor F.J. Ormeling, former President and Secretary/Treasurer of the ICA and gives a wide ranging review of the current status of cartography, how this status was attained and the way in which the subject is expected to evolve over the next decade. It is composed of two main sections. In the first, the present state of cartography in different countries is examined. The second section is a thematic view in which some of the major issues and developments in cartography are discussed in turn, including art and science in cartography, the character of historical cartography, the role of map making in developing countries, the impact of a possible ideal computer mapping facility and how cartography has changed in recent years.  There are international contributions from authors distinguished and internationally recognised in cartography and related fields and who have had a significant input to the ICA.

This report, produced between 1984 and 1987 in a bilingual edition (English and French), provides a wealth of information on a wide variety of cartographic applications which are being developed to make effective use of new data that is now being collected by Earth observation satellites.  At a time when natural resource development and environmental problems have to be taken into account in their entirety, satellites provide an exceptional means of evaluating, synthesizing and creating geographic information. The production of new images, such as the Landsat Thematic Mapper, the SPOT High Resolution Visible Sensor and the adoption meteorological images such as AVHRR sensors on NOAA satellites, which have been extended to thematic domains such as agriculture and glaciology, have led to many new developments as well as problems for the cartographer. These problems are numerous and varied and recur frequently depending on the images and themes being processed e.g. how to select the graphic specification of maps and legends and account for classification accuracy; how to introduce the minimum of topographical data into an image in order to supply users with an adequate geographic reference; when using a physical terrain image, on which, by definition there are no `blanks' and where no details have been eliminated, how to overcome conceptual difficulties e.g. the side by side placing of different semiological information; the interpretation levels left to reader; achieving a balance between objectivity and readability. Obviously the cartographers role is of prime importance in solving these problems.  In order to illustrate the way in which this information is presented, the report provides samples from 33 thematic applications taken from 13 different categories, including agriculture, town planning and water resources. Each application is provided with a descriptive note both in English and French indicating the objective, method and results obtained. This volume provides an important record of current developments in thematic mapping from satellite imagery and should be essential reference for all cartographers.

Colloids in the Aquatic Environment covers the proceedings of the International Symposium by the same title, held at the University College London on September 7-9, 1992, organized by the SCI Colloid and Surface Chemistry Group.   This book is divided into 20 chapters and begins with an introduction to the fundamentals of surface structure and reactivity. The succeeding chapters deal with molecular mass determination of humic substances from natural waters, the biospecific mechanism of double layer formation, the dynamics of colloid deposition in porous media, and the evaluation of surface area and size distributions of soil particles. These topics are followed by discussions of the transport and capture of colloids; colloidal stability of natural organic matter; the hydrolytic precipitation and modeling ion binding by humic acids; and the thermodynamic aspects and photoelectrophoresis of colloids. Other chapters explore the colloidal transfer in several aquatic environments. The final chapters consider the mechanism of colloid detachment, speciation, partitioning, and stability. These chapters also look into a hybrid equilibrium model of solute transport in porous media in the presence of colloids.  This book will be of great value to civil and environmental engineers.

Topographic mapping plays a basic and important role within the extensive field of cartography.  In recent years, this type of mapping has become somewhat neglected and available literature is normally restricted to details concerning the programmes of individual countries often presented in the form of monographs.  Topographic maps are essential tools for use in development projects, resource exploitation, the planning of construction, infrastructure and recreation.  They also give detailed illustration of the relative degrees of development of areas within a landscape and are thus unique in demonstrating the cultural status of a country. This book is the second of three volumes and gives details and examples of topographic maps from Central and South America and Africa. The information supplied for each country consists of a text, including a brief history of the development of topographic mapping, geodetic data, map scales and series, as well as extracts of maps and index sheets illustrating the present status of map coverage within that country.  There is currently no other work employing the approach adopted in assembling this inventory. This work is a comprehensive and important reference and source book for information in the field of topographic mapping.

New Approaches to the Study of Behavioural Choice

# data[].attributes.description
The traditional view of motor systems as a linear chain of elements switched on and off by command neurons has become increasingly difficult to maintain in the face of accumulating evidence against the existence of command elements. So far, however, the general formulation of an alternative approach has been lacking. This book, by summarising the evidence against the linear approach to motor systems, argues forcefully against it. Analyses are presented of motor systems ranging from the lobster stomatogastric system through molluscan systems, leech movement, insect singing and locomotion, fish and amphibian behaviour, to goal-directed a movements in primates and volitional movements in humans. Comparison of these motor systems reveal the existence of some general principles underlying motor control and behavioural choice such that motor systems appear generally to be parallel, distributed processing networks. By discussing the treatment of motor systems in terms of parallel distributed processing systems, this book presents in concentrated form an alternative to the earlier view of motor systems. As such, the book is a must for all neuroscientists interested in the organisation of motor systems and the neuronal substrates of behavioural choice.
