However, such extractions yield a complex mixture of different lipid classes which have to be purified further for quantitative analysis. Moreover, the crude lipid extract will be contami nated by other hydrophobic molecules, e.g. by intrinsic membrane proteins. Of the various types of separation processes, thin layer and column chromatography are most useful for intact lipids. High performance liquid chromatography (HPLC) is also rapidly becoming more popular, especially for the fractionation of molecular species of a given lipid class. The most powerful tool for quantitation of the majority of lipids is gas liquid chromatography (GLC). The method is very sensitive and, if adapted with capillary columns, can provide information with regard to such subtle features as the position or configuration of substitutions along acyl chains. By coupling GLC or HPLC to a radioactivity detector, then the techniques are also very useful for metabolic measurements. Although research laboratories use generally sophisticated analytical methods such as GLC to analyse and quantify lipid samples, chemical derivatie:ations are often used in hospitals. For these methods, the lipid samples are derivatized to yield a product which can be measured simply and accurately-usually by colour. Thus, total triacylglycerol, cholesterol or phospholipid-phosphorus can be quantitated conveniently without bothering with the extra information of molecular species, etc. which might be determined by more thorough analyses.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Over the years 1984 to 1989, we published a series of articles on the molding of thermoplastics, and of thermosetting materials, in the monthly magazine British Plastics and Rubber (B P & R). These articles were very well received and we also received a large number of requests for reprints. The articles were also translated into languages other than English. In order to cater for what is obviously a need in both the ther moplastics, and the thermosetting, molding industries, we there fore brought the information together and produced it in book form. To make the material easier to handle we produced it in the form of several books and this is one of them. We can only hope that the information so presented, serves you well and that you find the information useful. We in turn would like to thank the editor of the magazine B P & R for helping us in this matter. Thanks are also due to our many friends and colleagues throughout the molding industry for their useful help and advice: in particular, the company Moldflow (Europe) limited deserve a special mention as they allowed us to extract information from their extensive data base. 192 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Investigations of archaeological intrasite spatial patterns have generally taken one of two directions: studies that introduced and explored methods for the analysis of archaeological spatial patterns or those that described and analyzed the for mation of spatial patterns in actuaiistic-ethnographic, experimental, or natu ral-contexts. The archaeological studies were largely quantitative in nature, concerned with the recognition and definition of patterns; the actualistic efforts were often oriented more toward interpretation, dealing with how patterns formed and what they meant. Our research group on archaeological spatial analysis at the University of Wisconsin-Madison has been working for several years on both quantitative and interpretive problems. Both lines of investigation are closely related and are important complements. In order to demonstrate the convergence of archaeological and actualistic studies for the understanding of intrasite spatial patterns, we organized a sympo sium at the 52nd Annual Meeting of the Society of American Archaeology in Toronto, Canada, in May 1987. The symposium, titled 'The Interpretation of Stone Age Archaeological Spatial Patterns,' was organized into two sessions. The six papers presented in the morning session, five of which comprise Part I of this volume, focused on ethnoarchaeological and experimental research. Michael Schiffer was the discussant for this half of the symposium. Our intention for the ethnoarchaeological contributions to the symposium and volume was the delin eation of some of the significant accomplishments achieved thus far by actualistic studies regarding the formation of spatial patterns. 336 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains papers presented at the International Conference on Organic Superconductivity which was held May 20-24, 1990, at the Stanford Sierra Conference Center, South Lake Tahoe, California. In the twenty years since the First Conference on Organic Superconductivity was held (Hawaii, 1969), there has been remarkable progress in the field. At present, development is accelerating with contributions from many groups in many countries worldwide. The discovery of high Tc superconductivity by G. Bednorz and K. Muller in 1986 and subsequent developments in the ceramic superconductors have had an enormous impact on the field of superconductivity as a whole. This discovery occurred in an area entirely different from that of conventional superconduc tivity, underscoring the importance of the search for and study of novel materials of all kinds. We believe that the organics, with their wide range of structural, chemical, and physical properties, belong in this category of novel materials. This book reflects the efforts of researchers from various disciplines: physicists, chemists, and materials scientists. It addresses the normal and superconducting properties of organic materials, as well as the search for new compounds and new syntheses. We are pleased to note that one of these papers reports on the discovery of a new organic superconductor with a record high Tc in this class. One chapter is devoted to a comparison of organic superconductors and the cuprates, another, to the prospects of discovering other novel conducting or superconducting compounds. 404 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Companies succeed in international markets because of their competitive competence which, in large measure, is based on the level of knowledge and skill they bring to their international marketing activities. Public organizations in the export development and promotion field play a facilitating role in this process. Their mandate is to enhance the know-how of exporters and thereby assist foreign market entry, development and expansion. The interaction between these public organizations and the companies they exist to serve is the subject of this book. The book is wide-ranging and up-to-date. The work ofresearchers from 11 countries (in both the developed and developing world) is represented which means that a variety of perspectives are contained in the book. These contributions present the latest thinking on this important matter. The authors of each chapter are objective in their approach. Consequently, considerable attention is paid to the performance of the public organization support programs and activities. Each researcher comes to his/her own conclusions based on the individual work undertaken, but readers will fmd that certain common themes run through many ofthe chapters. The key objectives of the book are: 1. To provide academic researchers with a current and comprehensive treatment of the role played by public organizations in export development and promotion. 2. To expose professional readers (officials in relevant public organizations, consultants in the private sector or in international agencies) to a view of their field of interest that might be broader and more critical than normal. 388 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This treatise is focused on early aspects of fungal pathogenesis in plant and animal hosts. Our aim in choosing the topics and contributors was to demonstrate common approaches to studies of fungal-plant and fungal-animal interactions, particularly at the biochemical and molecular Ievels. For example, the initial events of adh'sion of fungal spores to the exposed surface tissues of the host are essential for subsequent invasion of the plant or animal and establishment of pathogenesis. A point of consensus among investigators who have directed their attention to such events in plants, insects, and vertebrates isthat spore adhesion to the host cuticle or epithelium is more than a simple binding event. lt is a complex and potentially pivotal process in fungal-plant interactions which 'may involve the secretion of ftuids that prepare the infection court for the development of morphological stages of the germling' and subsequent invasion of the host (Nicholson and Epstein, Chapter 1). The attachment of the fungal propagule to the arthropod cuticle is also 'mediated by the chemical components present on the outer layer of the spore wall and the epicuticle . . . . Initial attachment may be reinforced further by either the active secretion of adhesive materials or the modification of spore wall materiallocated at the [fungal spore arthropod] cuticle interface (Boucias and Pendland, Chapter 5). 586 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It was just over ten years ago, at Aspeniisgarden near Gothenburg, Sweden, that Pro fessor Alexandr Sergeevich Davydov presented his soliton theory for the storage and transport of biological energy in protein to scientists from Europe, North America and Japan. Since then, his ideas have been vigorously studied and investigated throughout the world. Many feel that Davydov's theory is an important contribution to biomolecu lar dynamics, but others caution that neglected dispersive effects may destroy the energy localization that arises ill his theory. It was to discuss these differences of opinion that we organized a NATO Advanced Research Workshop on 'Self-trapping of Vibrational Energy in Protein' from July 30 to August 5, 1989 at Hanstholm, Denmark. In addition to substantial financial support from the Special Programme on 'Chaos; Order and Patterns' of the NATO Scientific Affairs Division, we received it generous grant from the Danish Natural Science Research Council. We also acknowledge invalu able assistance provided by the interdepartmental center of nonlinear studies ('MIDIT' is the Danish acronym) as well as the Laboratory of Applied Mathematical Physics, both at the Technical University of Denmark. It is a particular pleasure to thank Lise Gudmandsen and Dorthe Th Ct. gersen for many forms of assistance before, during, and after the workshop. 548 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Of the three organizers of this NATO Advanced Research Workshop on 'Neocortex: Onto geny and Phylogeny', one derived most of his knowledge about neocortex from studies on birds, another had never studied any animal but the cat and could probably recognize not more than ten animal species, and the third had very limited experience with mountaineering. They had in common the belief that evolutionary thinking permeates what biologists do, but that evolution of species and structures cannot be directly experimentally addressed. Although the fossil record can provide some major insights, the inroad to the evolution of the brain is indirect, via comparative anatomy and developmental biology. By identifying similarities and differences between brain structures in the species at hand, comparative anatomy generates hypotheses of evolutionary transformations. By understanding the rules of morphological transformation, developmental biology can, in principle, estimate the likelihood that a given transformation may have actually occurred. The meeting was a way to check if this notion is viable, by gathering together scientists from these two fields. Standing, left to right: F. Ebner, V. Caviness, M. Weisskopf, B. Fritszch, N.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy The few general oncology text books are generally out of date. Single papers in specialized journal are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good in-depth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfortunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes that aim to meet this need. It is an attempt to establish a critical mass ofoncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, and easily available on a single library shelfor by a single personal subscription. We have approached the problem in the following fashion: first, by dividing the oncology literature into specific subdivisions such as lung cancer, genitourinary cancer, pediatric oncology, etc.;and second, by asking eminent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basic biology, and more. 196 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this volume we aim to present an easy-to-read account of the genus Saccharomyces that we hope will be of value to all students and researchers wishing to exploit this important genus, be it for academic or commer cial purposes. Individual chapters have been commissioned to cover specific aspects of the biology of Saccharomyces species: growth, genetics, and metabolism, with the emphasis on methodology. Basic principles are discussed without an over-detailed, step-by-step breakdown of specific techniques, and lengthy discussions of standard molecular, biological, and biochemical techniques (e. g. , polyacrylamide gel electrophoresis, protein purification, DNA sequencing) have been avoided. We hope the volume will provide a quick reference to the current status of a wide range of Saccharomyces-specific methodologies without focusing ex clusively on recent developments in molecular techniques which can be found in the ever increasing numbers of 'cloning manuals. ' By necessity, much of what is described in this volume concentrates on one particular species of Saccharomyces, namely Saccharomyces cerevisiae. This is not just a reflection of the authors' interests, but indicates the extent to which this simple eukaryote has been studied by biologists from all walks of life, for all sorts of reasons. If this volume can provide a broader knowledge base to the experienced yeast researcher, or ease the path of someone just starting work with Saccharomyces, then we will have achieved our aim. 348 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -S. Henin Versailles, France It was a pleasure for me to take part in the NATO Advanced Study Workshop for studies of 'Soil Colloids and their Associations in Soil Aggregates'. The meeting provided me with a welcome opportunity to renew acquaintances with respected colleagues in the various fields of Soil Science, to listen to their presentations, and be involved in discussions which were at the frontiers of the science which deals with the structures and the associations of the soil colloidal constituents. In my view the rapid advances in Soil Science, and the great benefits to agriculture from these, have their origins in the emerging understanding of the structures and the associations of the different soil colloids. It is clear that much research is still needed before the molecular details of the most important of the structures and of the interactions are fully understood. The associations between the soil colloids, and the manner in which they bind to or hold the other constituents of soils in aggregates is fundamental to soil fertility. and the Modem intensive agriculture leads to the degradation of soil structure subsequent loss through erosion of a resource that is vital for the production of food. This degradation is considered to result primarily from the biological oxidation of the indigenous soil organic matter, and from the failure to return to the soil sufficient organic residues to compensate for such losses. 620 pp. Englisch.
