This item is printed on demand - it takes 3-4 days longer - Neuware -Although interactions between nanoparticles and microorganisms in the environment are unavoidable and commonplace, it is still not clear what potential effects they may have. Metallic Nanocrystallites and their Interface with Microbial Systems not only illustrates how microbes and these particular nanoparticles interact but also it describes the consequences of these interactions. This brief discusses the impact of gold, silver, zinc oxide, and cerium oxide nanoparticles on the growth and viability of both Gram-negative and Gram-positive bacterium is discussed. Moreover, it analyses the relationship between bacterial growth inhibition, reactive oxygen species generation, the regulation of transcriptional stress genomes, and the toxicity of these materials. Finally, it reviews the specific metallic nanomaterials and highlights their modes of synthesis, reactivity at surfaces, and the importance of assay procedures in determining their toxicity levels. Various microscopy techniques used to determine their mechanisms of action are also presented. Metallic Nanocrystallites and their Interface with Microbial Systems will be a valuable source to the scientific and industrial community as well as to students and researchers in microbiology, biotechnology, nanotechnology, toxicology, materials science, biomedical engineering, cell and molecular biology. 84 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Public concern about the safety and healthfulness of the food supply grew markedly during the 1980s. Numerous government, academic, interest group, and media reports questioning the adequacy of the food safety regulatory system formed the basis for this increase in concern. While public concern focused most directly on pesticide residues in food, scientists emphasized the risks of illness associated with microbiological contamination of food. Much additional attention was focused on the food supply as a result of the striking consensus on dietary recommendations that emerged in the late 1980s based on increased scientific knowledge of linkages between diet and health. Relatively little research on the economic aspects of food safety and nutrition issues had been conducted up to the mid-1980s. These aspects are complex. On the consumer demand side, they include consumers' perceptions of the risks associated with particular food products, how demographic characteristics influence consumers' processing of risk information and subsequent changes in food demand behavior, and the monetary value consumers might place on changes in the risk profiles of products. The economic benefits and costs associated with current food consumption patterns are a major determinant of demand for improved food safety and dietary change through government regulation. While a more complete picture of risks, benefits, and costs has been emerging recently, much is yet unknown. 372 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Synthetic polymers make excellent specimens for light microscopy. Despite this, the use of the technique, at least in its advanced forms, is not so widespread as might be expected. Although reliable and relevant data are difficult to find and quantify, it seems that in other fields of materials science and technology there is a greater readiness to tum to the microscope in research, in industrial problem solving, or for quality assessment and control. It also seems that the reasons for the present situation are partly historical, partly the result of the structure of the plastics and rubber industries, and partly the education and training background of senior staff who tend to be chemistry or engineering based. In neither field does light microscopy feature strongly in the basic training. The primary aim of this book is to provide some insight into the range oflight microscopy techniques applicable to polymeric specimens, and to highlight typical applications to commercial polymers and polymer products. Where appropriate, the optical techniques involved are discussed in some detail. However, it has not been the intention to produce a light microscopy textbook dealing with the principles and design of the basic instrument. Many such texts are available, and selected examples are cited in the reference list at the end of most chapters. 300 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -One of the most exciting prospects for optical fibres made from fluoride glasses is the possibility of providing long distance optical communication systems without the need for repeaters. This objective has stimulated much of the work into fluoride glasses over the past ten years, and has prompted the writing of this book. It has also emerged that fluoride fibres can transmit both visible and infrared energy (from about 0.5 to 5 ,urn) and that they have many applications outside the field of telecommunications. These include optical fibre sensors (particularly in remote infrared spectroscopy), laser surgery and fibre lasers. Several companies are now established in the field, and good quality fluoride fibres are available from sources throughout the USA, Europe and Japan. Moreover, the first commercial instruments based on fluoride fibres are finding their way to the market place and these fibres will undoubtedly form the basis of many more instruments yet to be developed. The work presented in this book represents the field both from an academic understanding of the materials and ways to convert them into fibre, and from a practical and commercial viewpoint. The principal author and some of the co authors are based at the British Telecom Research Laboratories in the UK. 280 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I would like to present some definitions which will be helpful in understanding the purpose of this book. From The American Heritage Dictionary of the En glish Language: Engineer 1. A person who skillfully or shrewdly manages an enterprise. 2. To plan, construct, and manage, as an engineer. 3. To plan, manage, and put through by skillful acts, or contrivance. Engineering 1. The application of scientific principles to practical ends as the design, con struction, and operation of efficient and economical structures, equipment and systems. 2. The profession of, or work performed by an engineer. Some words encountered in the definitions of engineer and engineering are Skillfully, Plan, and Manage. This book is concerned with engineering the man ufacture of printed circuit boards, and is dedicated to those people engaged in designing, planning, manufacturing, and achieving quality assurance in printed circuits. In The Handbook of Printed Circuit Manufacturing (Van Nostrand Reinhold, 1985), I presented detailed practical and theoretical information on the opera tions involved in manufacturing printed circuits. It is possible to perform each operation in an optimum fashion, and still leave room for improvement. Much of that room for improvement requires the skillful application of scientific prin ciples, planning, and management. It is the goal of this book to provide a sound background in industry standards and specifications, blueprint comprehension, artwork inspection, processes and tolerances, planning and quality assurance. 260 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The impetus to create this book originated from several concerns. One of these was the perceived value to the industry of a collection in one volume of a wide range of information pertinent to the reasons and techniques for de fluxing printed wiring assemblies (PWAs). This book is expected to be of use not only to those engaged in the electronics packaging industry but also to those in related fields seeking information concerning viable methods of dealing with one of the en vironmental issues of our time: the destruction of the ozone layer surrounding and protecting the planet with which we have been entrusted. The volume of information relative to providing PW As free of residues ad versely impacting operation, reliability, and life of electronic products is grow ing, and it will continue to expand at an accelerated rate as we seek to match our technology needs and desires with our environmental responsibilities. At the time ofthis writing, which has spanned the latter portion of 1989 and early 1990, the issue of choosing a new approach to producing PW As free of detrimental residues while using environmentally acceptable manufacturing techniques ap peared to be the major concern of the vast majority of those involved in the printed wiring assembly industry. To many this meant the use of different clean ing media and/or process or equipment enhancements; to others it meant the elimination of the need to clean through materials or process changes. 244 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The title of this book is Techniques in Corporate Manpower Planning: Methods and Applications. Manpower planning, also called personnel plan ning, implies the analysis of possible discrepancies in the future between personnel demand and supply. Personnel demand will also be called person nel requirement; and personnel supply, personnel availability. The notion of corporate manpower planning refers to the planning of personnel on the level of an industrial or governmental organization. As such, it does not stand for manpower planning for branches of industries or labor market studies of countries or international communities. One type of manpower planning is the planning of short-term succes sions of managers or the assignment planning of positions for individual employees for the next year. In fact, this type of short-term manpower plan ning is always executed, whether formally or informally, centrally or other wise. Another type of manpower planning, however, may be executed to match the requirement for and availability of personnel for the medium and long term. This type of manpower planning considers groups of employees rather than individuals. Our goal is to consider medium- and long-term manpower planning for groups of employees. We call this the multicategory vii Vlll PREFACE approach to manpower planning. In our view, this medium-and long-term personnel planning provides the conditions for individual manpower plan ning or for personnel development. 200 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Over the last decade, Africa has taken a central position in the search for the timing and mechanisms leading to modern human origins, and the rich archaeological and human paleontological record of North Africa is critical to this search. In this volume, we bring together new research into the archaeology, human paleontology, chronology, and environmental context of modern human origins in North Africa. The result is a volume that better integrates the North African record into the modern human origins debate and at the same time highlights the research questions that are currently the focus of continued work in the area. 268 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this book is to provide a new insight on Neanderthal behaviour using the data recovered in level J of Romaní rockshelter (north-eastern Spain). Due to the sedimentary dynamics that formed the Romaní deposit, the occupation layers are characterized by a high temporal resolution, which makes it easier to interprete the archaeological data in behavioural terms. In addition, the different analytical domains (geoarchaeology, lithic technology, zooarchaeology, taphonomy, anthracology, palaeontology) are addressed from a spatial perspective that is basic to understand human behaviour, but also to evaluate the behavioural inferences in the framework of the archaeological formation processes. 428 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In many respects, Brentano conducted pioneering analyses of problems that are currently in the focus of cognitive science and artificial intelligence: from the problem of reference to that of representation, from the problem of categorial classification to ontology and the cognitive analysis of natural language.Brentano, in fact, dealt with and wrote on questions concerning the auditory stream (temporal apprehension), visual perception (continua, point of view, three-dimensional construction of phenomenal objects), intentionality, imagery, and conceptual space, considering these pertaining to a metaphysical enquiry. Moreover, Brentano displayed clear awareness of the complexity of problems and of the interrelations among different areas of inquiry. From this point of view, his theory, however complex, offers elements for the treatment of problems currently under investigation.Brentano's work is an antidote against physicalism and logicism, which dominated the 20th century epistemology, and as such appears to be a good philosophy candidate for cognitive science.'A set of knotty questions are implied in the very title of Brentano's work 'Psychology from an empirical standpoint'. To solve them, Albertazzi guides us systematically through Brentano's life and works, investigating into the inherent complexity of both his view of mental life and the related methodology. In so doing, she discloses a number of threads into the open texture of modern philosophy of mind.'Lia Formigari, Ordinary professor of Philosophy of Language, La Sapienza, Rome, Italy 392 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since we produced Fats and Oils: Chemistry and Technology in 1980, the trend we anticipated to up-date the classical texts of oils and fats has manifested itself. Bailey's famous textbook has been completely revised and a second edition of Bernardini's work has been produced. The present text is an attempt to provide some insight into the current state of the art. Chapter 1 discusses the physical properties of oils and fats with special reference to those properties which can be monitored to give an in dication of the suitability of fats for chocolate production. The physical properties of the fats are often determined by the order in which the fatty acids are attached to the glyceride molecule. Ram Bhati, in the last article he wrote before his death, showed how mass spectrometry and chemical methods could be used to determine the sequence of fatty acids. Ram's essentially practical approach to the problem is exemplified by the section dealing with the experimental details of the techniques. Chapter 3 outlines some of the problems which can arise in industry when the lipid part of a foodstuff undergoes oxidation, whilst in Chapter 4 Patterson describes the major technique, hydrogenation, which is used to circumvent the problems caused by oxidation of the unsaturated fatty acids. In Chapter 4 the essentials of the theory are given to enable the reader to appreciate the design features of the apparatus. Chapter 5 deals with the analysis, mainly chromatographic, of lipids. 204 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fiber optics is a transmission technique that uses electrical signals to modulate a light source and thereby produce an optical signal proportional to the electrical signal. These optical signals contain information that is transmitted via a glass waveguide to a light-sensitive receiver. Fiber optics has a distinct advantage over copper networks for some applications. The objective of this book is to explore monomode, as opposed to multimode, applications of fiber optics to local area networks (LANs), which have become a rather important aspect of this technology because of the ever-increasing growth of LANs. Monomode fiber optics requires the use of coherent light sources such as laser diodes, YAGs, and HeNe lasers, to name just a few. It has some distinct advantages over multimode that this text will investigate in a cursory manner. (The author's previous book on multimode fiber optics, Fiber Optic Design and Applications, published by Reston, would be helpful but not necessary to aug ment this text.) Monomode (or single-mode) fiber optics is the present direction of the state of-the-art because of its superior performance. Since a few problems existed that limited the growth of monomode technology at the time this book was being written, several sections of the text will be devoted to examining the shortcom ings as well as the performance advantages of this technology. 508 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Surface Mount Technology is not a technology of tommorrow but a technology of today. It provides a quantum jump in the packaging tech nology to produce state-of-the-art miniaturized electronic products. How ever, in order to take advantage of this technology, a complete infrastruc ture must be put in place. This requires considerable investment in human and capital resources. Intel corporation has made these investments to keep its customers for components and systems on the leading edge of technology. Based on the experience of putting this infrastructure in place for system products, this book is written for managers who need to manage the risk during its implementation, and the practicing engineers who need to improve the design and manufacturing processes for improved yield and cost reduction. To accomplish this task, I have not only culled the infor mation from published materials, but have also depended on input from both my colleagues in Intel and such outside organizations as the Institute of interconnecting and Packaging electronic Circuits (IPC) , the Electronics Industries Association (EIA), and the Surface Mount Council. But the underlying basis for this book has been my first-hand experience in im plementing this technology for Intel Systems Group and my experience at Boeing, my previous employer. In a fast-changing technology like SMT, it is very easy to have obsolete information even before the book is published. For this reason, I have concentrated on the basic principles and practice of the technology. 640 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this text is to increase your understanding of the methods employed for improving the quality of printed circuit boards (PCBs) in a practical manufacturing environment, by discussing printed circuit board faults and the test strategies implemented to detect these faults. This text emphasizes in-circuit testing as a prime test and diagnostic technique. Test strategies are described - implementing functional board testers, in-circuit board testers, in-circuit analyzers, and loaded board shorts testers. Also discussed are in-circuit tester's hardware, software, fix turing, and programming. Specific attention has been given to the in-circuit tester's capabilities and limitations, features and benefits, advantages and disadvantages. Chapter 5, as part of the total production testing process, discusses rework stations, network ing, and test area management. Chapter 8 is devoted to discussing the benefits derived by employing in-circuit testing in the service repair arena. This text concludes with chapters on vendor investiga tion and a financial justification. Additional emphasis is placed on having design engineering acquire an interest in manufacturability, testability, and the importance of consulting with manufacturing early in the design process. This book is designed for ease of reading and comprehension for all levels of interest: ATE students, fust-time ATE users, as well as those involved in test, manufacturing, quality control or assurance, production, engineering, and management. 268 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Society is a nexus of individual perceptions. The world is as we each see it, no more and no less. To hope that we shall all agree on what is good or bad is to hope in vain. This is not solipsism transferred to moral philosophy; it is realism born of observation. This book tries to remind its readers that you can be responsible only if you understand the basis of your responsibility; that you can exercise responsibility only if you have the power to do so; that you cannot lay down a conceptual framework of behavior in business if you have no framework of life; that every facet of your conduct as a manager and employee involves a delicate balance between rebellion and absolute conformity. Indeed, it may be that the hardest lesson is that of learning that compliance and silence and obedience are frequently more desirable than protest when all stands to be lost. To gamble on a poor card hand is the act of either an excessively foolish or a supremely clever man; since the proper judgment of risk is an uncommon facility, poor hands are normally lost. There is no such thing as a corporate attitude, just as there is no such thing as the will of the people. 244 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This textbook covers essentials of traditional and modern fluid dynamics, i. e. , the fundamentals of and basic applications in fluid mechanics and convection heat transfer with brief excursions into fluid-particle dynamics and solid mechanics. Specifically, it is suggested that the book can be used to enhance the knowledge base and skill level of engineering and physics students in macro-scale fluid mechanics (see Chaps. 1-5 and 10), followed by an int- ductory excursion into micro-scale fluid dynamics (see Chaps. 6 to 9). These ten chapters are rather self-contained, i. e. , most of the material of Chaps. 1-10 (or selectively just certain chapters) could be taught in one course, based on the students' background. Typically, serious seniors and first-year graduate students form a receptive audience (see sample syllabus). Such as target group of students would have had prerequisites in thermodynamics, fluid mechanics and solid mechanics, where Part A would be a welcomed refresher. While introductory fluid mechanics books present the material in progressive order, i. e. , employing an inductive approach from the simple to the more difficult, the present text adopts more of a deductive approach. Indeed, understanding the derivation of the basic equations and then formulating the system-specific equations with suitable boundary conditions are two key steps for proper problem solutions. 640 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volu~e contains the complete proceedings of the second NATO Advanced Study Institute organised to relate co~uni cation theory with allied subjects, and thus to single out themes which, though peripheral at present, are gaining in importance because of recent developments in theoretical investi gations by communication experts. In 1974 we attempted to promote an interchange of ideas between specialists in Signal Processing and in Control and System Sciences \*. This time we tried to concentrate on probabilistic aspects of communication theory and practice and of the allied science of random process theory, with its novel and exciting approach to the mathematical foundations of noise phenomena. The topics presented here have been chosen with the above in view, to enlarge ideas and to diffuse results in the two allied subjects, by providing the opportunity for gaining insight in depth into new developments. These topics fall broadly into 10 distinct parts. Each starts with two or more basic presentations of a tutorial nature, followed by one or more detailed exa~inations of particular aspects of the subject. In addition, some parts are concluded with reports of panel dis cuss~ons organised to consider a particularly pertinent issue. 996 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Second Volume of 'Equilibrium between Phases of Matter', when compared with the First Volume, by H.A.J. Oonk and M.T. Calvet, published in 2008, amounts to an extension of subjects, and a deepening of understanding. In the first three sections of the text an extension is given of the theory on isobaric binary systems. The fourth section gives an account of the thermodynamic analyses of four isobaric binary key systems, highlighting the power of empirical, (exo)thermodynamic correlations. The fifth section is devoted to the thermodynamic description of ternary systems. The last three sections concentrate on the properties of materials, and the phase behaviour of systems under the conditions of high temperature and high pressure - conditions that prevail in the interior of the Earth. A new equation of state is the subject of the sixth section. In the seventh section a move is made to statistical thermodynamics and vibrational models; the description of the systems has changed from mathematical to physical. The last section is on the system MgO - SiO2, looked upon from a geophysical point of view.Throughout the work high priority is given to the thermodynamic assessment of experimental data; numerous end-of-section exercises and their solutions are included. Along with the First Volume, the work is useful for materials scientists and geophysicists as a reference text.AudienceVolume II is a lecture book for postgraduate students in chemistry, chemical engineering, geology and metallurgy. It is highly useful as a recommended text for teachers and researchers in all fields of materials science. 308 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph has its origins in a two-day meeting with the same title held in London, England in the spring of 1987. The idea for the meeting came from members of the UK Mineral and Rock Physics Group. It was held under the auspices of, and made possible by the generous support of, the Mineralogical Society of Great Britain and Ireland. Additional financial assistance was provided by ECC International pIc and the Cookson Group pIc. The aims of the London meeting were to survey the current state of knowledge about deformation processes in non-metallic materials and to bring together both experts and less experienced Earth scientists and ceramicists who normally had little contact but shared common interests in deformation mechanisms. This monograph has similar aims and, indeed, most of its authors were keynote speakers at the meeting. Consequently, most of the contributions contain a review element in addition to the presentation and discussion of new results. In adopting this format, the editors hope that the monograph will provide a valuable state-of-the-art sourcebook, both to active researchers and also to graduate students just starting in the relevant fields. 444 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is more and more evident that our living system is completely disturbed by human intrusion. Such intrusion affects the functioning of entire systems in ways we do not yet fully understand. We use paradigms such as the disturbance to cover large and deep gaps in our scienti c knowledge. Human ecology is an uncertain terrain for anthropologists, geographers, and ecologists and rarely is expanded to include the social and economic realms. The integration of different disciplines and the application of their many paradigms to problems of environmental complexity remains a distant goal despite the many efforts that have been made to achieve it. Philosophical and semantic barriers are erected when such integration is pursued by pioneering scientists. Recently, evolutionary ecology has shown great interest in the spatial processes well described by the emerging discipline of landscape ecology. But this interest takes the form of pure curiosity or at worst, of skepticism toward the real capacity of landscape ecology to contribute to the advancement of ecological science. The past two centuries have been characterized by huge changes occurring in the entire ecosphere. Global changes are the effects of human intervention at a planetary scale, with consequent degradation of the environment creating an e- logical debt for future generations. On the other side of the issue, new technologies have improved the welfare of billions of people and have given hope to many other billions that they may also see such improvement in the near future. 184 pp. Englisch.

It includes chapters on anatomy, physiology and optics to explain the simple elements of the basic sciences that are needed to understand ophthalmology. The section on examination describes the common investigations in an eye department in the hope that reports from ophthalmologists may become more easily understood. The clinical chapters represent 5 years of ophthalmic referrals by local family doctors in a part rural and part suburban area. This selection of eye disease therefore excludes some of the rare conditions, but includes those common problems that can worry not only the busy family doctor, but also the hard pressed medical student. 7 Anatomy and Physiology The sense of vision depends on the integrity of a set of Internal Eye anatomical and physiological factors, a study of which The eye consists of three concentric layers.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The economics of forestry has always fascinated me as one of the most brain-taxing cases in economics. As an investment forestry is different from many other projects as it has unusually long gestation periods. For example, in the United Kingdom it takes over 40 years to grow coniferous and over 100 years for deciduous timber. These long gestation periods make it very clear how import ant are the magnitude of the discount rate and the method of discounting in the evaluation of investment projects. Any errors in these will misguide investors in forestry one way or the other. In addition, forestry redistributes income between gener ations. Its long gestation periods make it obvious that more than one generation will be involved in any venture. When we plant trees we know that the bulk of the benefits will be captured by future generations. Conversely, when we fell trees we reap the benefit of projects which were established in the past, mostly by generations who are long gone. So far most economists have devoted their time and energy to analysing income distribution in an intragenerational context, and this is a very sensitive and controversial issue. After all, most revolutions have taken place because of the uneven income distribution which was oppressive for the majority. Forestry helps us to study the case from the viewpoint of different generations. Forestry necessitates estimating timber prices a long time ahead. 200 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is directed towards post-graduates who have passed Part I of the examination for Membership of the Royal College of Physicians and are preparing for Part II. However, it is hoped that physicians at all stages of their careers will find some parts that interest them. Most of the material has appeared in the Hospital Update series, 'Preparation for MRCP', but this has been modified and expanded; many useful points arising from correspondence relating to the series have been included, and the authors would like to express their thanks to those who have written. It is not intended that this should be used as a work of reference, although there is detailed discussion of some subjects. Only the written part of the examination is dealt with in detail, but the introduction contains hints on tackling the clinical sections which the authors hope the candidates will find valuable. There is, however, no substitute for clinical practice under supervision. The questions in Vll PREFACE the written section of the examination require short answers so that marking may be easy and objective. This book contains questions similar to those that may be encountered in the examination, but the answers have been expanded as a basis for discussion. It is hoped that this will encourage the candidate to read around the subjects covered, and the authors recommend that the questions are used as a basis for group discussion, as answers other than those in the text may be considered. 200 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -THE HABITAT Nairobi National Park lies to the south-southeast of the capital of Kenya, Nairobi, where the Athi Plains meet the Eastern escarpment of the Rift Valley. These plains form part of the semi-arid highland plateau lying between the coast and the Rift Valley. Both the city itself, and the Park bordering it, are a meeting place of two generally distinct types of landscape and climate. While to the east-southeast are semi-arid plains with grasslands and scattered trees, the western-north western parts are higher, hilly, cooler, more humid and support lush forests. The combination of latitude-a little over one degree south of the Equator -and altitude-average of 1600 m. (5000-5500 ft.) -combine to give Nairobi a most equable climate where the temperature varies during the year between about 11 degrees and 27 degrees centigrade (mean minimum and mean maximum for eight years). However, considerable changes are usually experienced within each day and a rise from 14 degrees C at 0600 hours to 22 degrees at 1100 hours is not unusual. Nairobi Park has a unique concentration of wild animals living in their natural habitat less than 10 km. from the centre of a modern city of half a million people. The only interference with the natural course of events in the Park is that normally required for the proper management of a game park, such as maintenance of roads and dams, and, in this particular case, partial fencing towards the city. 164 pp. Englisch.

No plant or animal lives in isolation. They all belong to one or other community and fit into this community. 2. The environment allows only one biocoenosis which harmonises with its properties. It provides the community with place, food, water and energy. 3. Every biocoenosis is organized in the space on and in the soil, needs a minimum area, and has only a limited number of contact communities. 4. All functions are organized in time, as shown by daily, seasonal and other rhythms. s. There is an endogenous, functional organisation which allows only a limited number of plants or animals to live together. 6. The result of a sociological structure is work, as shown by the renova tion of the community, the production of organic compounds, the for mation and transformation of soil. 7. All normal biocoenoses are harmonic. LITERATUUR TUXEN, R.: Vegetations-und standortskundliche Grundlagen flir Rekulti vierungsmaBnahmen in Tagebaugebieten. - Natur u. Landschaft 34 (3): 34/5.
