Catalyst Design for Tailor-Made Polyolefins
1st Edition
Volume 89
M. Terano + 1 more
English
Recent development of olefin polymerization catalysts has caused marked changes in both industrial and academic research. Industrial use of homogeneous metallocene catalysts has already begun in the fields of high density polyethylene and syndiotactic polypropylene. Moreover, important data have been obtained from academic investigations which have proved useful for understanding conventional heterogeneous Ziegler-Natta catalysts. From the industrial viewpoint, however, heterogeneous high-yield catalysts seem to be more important.The present volume contains invited lectures and contributed papers. The following topics are covered: (1) Heterogeneous Catalysts, (2) Metallocene Catalysts and (3) New Trends in the Polyolefin Industry.

Solid base catalysts are also gaining increasing recognition as potential catalysts. Both acidic and basic catalysts are promising not only with respect to acid and base-catalyzed reactions but also in materials sciences, such as the production of adsorbents, sensors, ceramics, etc.The present volume presents the text of 21 invited oral presentations and 58 poster presentations. The material covers a wide range of aspects on acid-base catalysis, from quantum chemistry to industrialized processes.
Aquaculture Water Reuse Systems: Engineering Design and Management
1st Edition
M.B. Timmons + 1 more
English
The demand for high quality aquacultured products and an increasing concern for resource conservation has led individuals and large corporations to invest time and money in commercial scale recirculating production systems. However, there are relatively few reports of profitable recirculating production systems in operation. There is little doubt that most fish reared in ponds, floating net pens, or raceways can be produced in commercial scale recirculating systems.The objective of this book is to provide basic information and analytical skills for the reader so that they may make the proper design or investment decisions concerning water reuse and recycle systems. The chapters of this book are sequenced to provide continuity to a basic approach that would be used in designing a water reuse or recycle system. The chapter authors contributing to this book have written extensively in the literature already on the particular subject being addressed in their chapter.Considerable background information on the basic processes being presented is also given in each chapter to supplement the basic design information being provided. These chapters should provide the reader with essentially all the information required in order to design and manage a water reuse system.The book is written for engineers and biologists working in the area of intensive fish culture. The text should also prove useful as a design manual for practising aquaculturists and as a resource of current "state-of-the-art" methodologies associated with water reuse systems.

The Self-Organizing Brain: From Growth Cones to Functional Networks
1st Edition
Volume 102
M.A. Corner + 3 more
English
This book concentrates on the organizational level of neurons and neuronal networks under the unifying theme "The Self-Organizing Brain - From Growth Cones to Functional Networks". Such a theme is attractive because it incorporates all phases in the emergence of complexity and (adaptive) organization, as well as involving processes that remain operative in the mature state.The order of the sections follows successive levels of organization from neuronal growth cones, neurite formation, neuronal morphology and signal processing to network development, network dynamics and, finally, to the formation of functional circuits.
Nordic Radioecology
The Transfer of Radionuclides through Nordic Ecosystems to Man
1st Edition
Volume 62
H. Dahlgaard
English
The present treatise is the final milestone in the radioecology programme, RAD, carried out from 1990 to 1993 under the Nordic Committee for Nuclear Safety Research, NKS. The book, one of the few in its field to have achieved international publication, is centred on the contamination of Nordic environments with radionuclides from the Chernobyl accident. It contains 30 contributions mainly describing the flow of radiocaesium through aquatic, agricultural, forest, and alpine ecosystems, as well as quality assurance and doses to man. A series of original papers on various aspects of Nordic post-Chernobyl radioecology by leading Nordic scientists is also included, along with terms & units definitions, indexes, and an executive summary.The volume will be invaluable to all scientists and professionals in radioecology, radiation protection, trace element cycling and environmental contamination. It will also be relevant to general evironmental management/human contamination/civil defence officials.
Homing Mechanisms and Cellular Targeting
1st Edition
Volume 9
B.R. Zetter
English
While some cells divide, live, and die all in the same tissue locale, others travel freely throughout the body, originating in one site and taking up residence at another. Many of these cells are targeted to specific locations. Embryonic cells travel in precise routes as the embryo develops. Inflammatory cells, such as neutrophils and monocytes, travel in the circulation to specific inflammatory sites, bypassing other normal tissues. Similarly, lymphocytes travel in the circulation and selectively emigrate through specific channels in lymph nodes or Peyers patches. Metastatic tumor cells also migrate in a selective manner from their primary site of origin to selected secondary organs. Until recently, information concerning cellular targeting was generally descriptive, consisting primarily of patterns of migration without any molecular detail as to the mechanisms of the targeting process. In the past several years, advances in cell and molecular biology techniques along with the development of monoclonal antibodies have enabled researchers to identify many of the molecules that mediate cellular homing and of metastatic tumor cell targeting to secondary sites. Consequently these two fields comprise the bulk of the chapters in this volume. In general, however, the contributions made in one field have not been rapidly transferred to other fields in which cell targeting has been studied, Although more descriptive information exists concerning pattern development and cell migration in the embryo, the study of the molecular mechanisms of such patterns has not developed as rapidly as that concerning mechanisms of leukocyte homing, for example. One important reason for assembling the diverse contributions to this volume is to bridge that gap and allow researchers and students of these different fields to compare the progress that has been made in each area, and to compare the molecules that have been discovered. This can often be quite productive as it appears that many of the adhesion molecules involved in inflammatory cell homing may also play a role in the dissemination of tumor cells to specific distant organs.
The Data Analysis Handbook
1st Edition
Volume 14
I.E. Frank + 1 more
English
Analyzing observed or measured data is an important step in applied sciences. The recent increase in computer capacity has resulted in a revolution both in data collection and data analysis. An increasing number of scientists, researchers and students are venturing into statistical data analysis; hence the need for more guidance in this field, which was previously dominated mainly by statisticians.This handbook fills the gap in the range of textbooks on data analysis. Written in a dictionary format, it will serve as a comprehensive reference book in a rapidly growing field. However, this book is more structured than an ordinary dictionary, where each entry is a separate, self-contained entity. The authors provide not only definitions and short descriptions, but also offer an overview of the different topics. Therefore, the handbook can also be used as a companion to textbooks for undergraduate or graduate courses.1700 entries are given in alphabetical order grouped into 20 topics and each topic is organized in a hierarchical fashion. Additional specific entries on a topic can be easily found by following the cross-references in a top-down manner. Several figures and tables are provided to enhance the comprehension of the topics and a list of acronyms helps to locate the full terminologies. The bibliography offers suggestions for further reading.

Solid State Magnetic Sensors
1st Edition
Volume 2
C.S. Roumenin
English
I am profoundly convinced that notwithstanding the great progress made in solid-state magnetic sensors, they are as yet in their cloudless infancy, whereas there is still so much lying ahead in a world, unlimited in time and space ... Good Heavens! They are a whole Universe into themselves.So expounds the author in his preface to this second volume in the exciting new series, Handbook of Sensors and Actuators. The publication presents a balanced view of the overall progress made in the field, whilst summing up scientific achievements as the groundwork for further development.Readers will find, for the first time, collected in one book, detailed information regarding the physical mechanisms of the origin of magnetosensitivity, the geometry and design of devices, operating modes, basic parameters and methods for their determination, the incorporation of transducers in circuits and smart solutions, many varied applications and other problems relevant to all the current Hall sensors, magnetodiodes, magnetotransistors, carrier-domain magnetometers, SQUID's (Superconducting Quantum Interference Devices) and similar transducers of magnetic energy. Particular attention is devoted to semiconductor magnetosensitive sensors and their microelectronic versions since development rates in this area signify a dominant research trend for the future.Undoubtedly this book will become a vital reference tool for the ever widening circle of researchers and engineers interested in solid-state magnetosensors. It also makes a fundamental contribution to the handbook series as a whole.
