This volume represents an effort to bring together communities of land-based hydrogeology and marine hydrogeology. The issues of submarine groundwater discharge and its opposite phenomenon of seawater invasion are discussed in this book from the geophysical, geochemical, biological, and engineering perspectives. This is where land hydrogeology and marine hydrogeology overlap. Submarine groundwater discharge is a rapidly developing research field. The SCOR and LOICZ of the IGBP have recently established a working group for this research. IASPO and IAHS under IUGG also recently formed a new joint committee "Seawater/Groundwater Interactions" to collaborate with oceanographers and hydrologists.

The other articles introduce frontier research topics in more typical land and marine environments, such as fluid flow in karst aquifers, the biological aspects of fluids in sedimentary basins and submarine sedimentary formations, respectively, and vigorous fluid flow in subsea formations and their significance in global tectonics. Geochemical characteristics of hydrothermal activities at a number of active continental margins are also reviewed, and multidisciplinary geophysical constraints of the permeability of young igneous oceanic crust are summarized. A variety of driving mechanisms for fluid flow is discussed in land and subsea formations; terrestrial hydraulic gradient, buoyancy driven free convection, tidally induced flow, flow induced by tectonic strain, flow due to sediment compaction.

This book will be of vital interest to all engineers and designers concerned with centrifugal pumps and turbines. Including statistical information derived from 20000 pumps and 700 turbines with capacities of 5gpm to 5000000gpm, this book offers the widest range and scope of information currently available. Statistical analyses suggest practical methods of increasing pump performance and provide valuable data for new design aspects.

The relevant techniques, vocabulary, currently available hardware architectures, and programming languages which provide the basic concepts of parallel computing are introduced in this book. In the future, we can expect to see massively parallel teraflop machines. These machines will be supported by gigabit network which allow grand-challenge problems to be solved by using several supercomputers and parallel machines concurrently.

Life cycle design is a proactive approach for integrating pollution prevention and resource conservation strategies into the development of more ecologically and economically sustainable product systems. Cross media pollutant transfer and the shifting of other impacts can be avoided by addressing the entire life cycle, which includes raw materials acquisition, materials processing, manufacturing and assembly, use and service, retirement, disposal and the ultimate fate of residuals.
The goal of life cycle design is to minimize aggregate risks and impacts over this life cycle. This goal can only be attained through the balancing of environmental, performance, cost, cultural, legal, and technical requirements of the product system. Concepts such as concurrent design, total quality management, cross- disciplinary teams, and multi-attribute decision making are essential elements of life cycle design that help meet these goals.
The framework for life cycle design was developed to be applicable for all product domains. It was written to assist not only design professionals but all other constituents who have an important role in life cycle design including corporate executives, product managers, production workers, distributors, environmental health and safety staff, purchasers, accountants, marketers, salespersons, legal staff, consumers, and government regulators. A coordinated effort is required to institute changes needed for successful implementation of life cycle design.
Part I seeks to promote the reduction of environmental imparts and health risks through a systems approach to design. The approach is based on the product life cycle, which includes raw materials acquisition and processing, manufacturing, use/service, resource recovery, and disposal. A life cycle design framework was developed to provide guidance for more effectively conserving resources and energy, preventing pollution, and reducing the aggregate environmental impacts and health risks associated with a product system. This framework addresses the product, process, distribution, and management/information components of each product system.
Part II describes the three components of a life cycle assessment (inventory analysis, impact analysis, and improvement analysis) as well as scoping activities, presents a brief overview of the development of the life cycle assessment process, and develops guidelines and principles for implementation of a product life cycle assessment. The major states in a life cycle are raw materials acquisition, manufacturing, consumer use/reuse/maintenance, and recycle/waste management. The basic steps of performing a life cycle inventory (defining the goals and system boundaries, including scoping; gathering and developing data; presenting and reviewing data; and interpreting and communicating results) are presented along with the general issues to be addressed. The system boundaries, assumptions, and conventions to be addressed in each stage of the inventory are presented.

This encyclopedia contains more than 5000 integer sequences, over half of which have never before been catalogued. Because the sequences are presented in the most natural form, and arranged for easy reference, this book is easier to use than the authors earlier classic "A Handbook of Integer Sequences. The Encyclopedia gives the name, mathematical description, and citations to literature for each sequence. Following sequences of particular interest, thereare essays on their origins, uses, and connections to related sequences (all cross-referenced). A valuable new feature to this text is the inclusion of a number of interesting diagrams and illustrations related to selected sequences.
The initial chapters are both amusing and enlightening. They serve as a delightful introduction to the subject and a short course on how to identify and work with integer sequences. This encyclopedia brings Sloanes ground-breaking "Handbook up to date, more than doubling its size, and linking both the old and the new material to an extensive bibliography (over 25 pages long), of current and classic references. An index to all the sequences in the book is also available separately on disk in Macintosh and IBM formats.
Key Features
* Contains more than 5000 integer sequences
* Gives the name and mathematical description of each sequence
* Provides citations to literature for each sequence
* Extensively cross-referenced
* Lists a bibliography of more than 25 pages

The book presents surveys describing recent developments in most of the primary subfields of
General Topology and its applications to Algebra and Analysis during the last decade. It follows freely
the previous edition (North Holland, 1992), Open Problems in Topology (North Holland, 1990) and
Handbook of Set-Theoretic Topology (North Holland, 1984). The book was prepared in
connection with the Prague Topological Symposium, held in 2001. During the last 10 years the focus
in General Topology changed and therefore the selection of topics differs slightly from those
chosen in 1992. The following areas experienced significant developments: Topological Groups, Function Spaces, Dimension Theory, Hyperspaces, Selections, Geometric Topology (including
Infinite-Dimensional Topology and the Geometry of Banach Spaces). Of course, not every important topic
could be included in this book.

Except surveys, the book contains several historical essays written by such eminent topologists as:
R.D. Anderson, W.W. Comfort, M. Henriksen, S. Mardeŝić, J. Nagata, M.E. Rudin, J.M. Smirnov (several reminiscences of L. Vietoris are added). In addition to extensive author and subject indexes, a list of all problems and questions posed in this book are added.

List of all authors of surveys:
A. Arhangel'skii, J. Baker and K. Kunen, H. Bennett and D. Lutzer, J. Dijkstra and J. van Mill, A. Dow, E. Glasner, G. Godefroy, G. Gruenhage, N. Hindman and D. Strauss, L. Hola and J. Pelant, K. Kawamura, H.-P. Kuenzi, W. Marciszewski, K. Martin and M. Mislove and M. Reed, R. Pol and H. Torunczyk, D. Repovs and P. Semenov, D. Shakhmatov, S. Solecki, M. Tkachenko.

This series provides a variety of different discussions on topics within the field of growth factors and cytokines in health and disease.

The book summarizes present scientific knowledge in plant physiology with regards to plant production. The authors, mainly professors of plant physiology at agricultural universities in Czechoslovakia, present the individual fields of plant physiology with regard to the demands of agricultural practice and education of students and doctorani at these universities.
The first chapters discuss metabolism ie. photosynthesis, respiration, mineral and heterotrophic nutrition, and water regime of plants. What follows is a discussion of the physiology of plant growth, development and movements, and finally resistance of plants against unfavourable abiotic and biotic effects.
The book shows how to increase the yield of crops by manipulating photosynthesis and also studies the possible flow of photosynthetic products to the commercially valuable parts of the biomass. Rational plant production, however, cannot do without knowledge of plant nutrition and water regime as a theoretical basis for fertilization and irrigation. The reader will find this knowledge detailed as well as information about the ecological and physiological principles of the resistance of plants against drought, frost, heat, diseases and other unfavourable effects.

Breast cancer research has never been in such an exciting and hopeful phase as today. From a clinical perspective, the discovery of genetic markers of risk in a proportion of familial breast cancer cases has opened up new vistas for understanding and ultimately preventing this disease. On the other hand, aggressive - even daring - therapies are being proven to be effective against advanced breast cancer. For the breast cancer experimentalist, this is also a time of great advance. Although animal and cell culture breast cancer models have proven to be of great use, there are now increasing opportunities to test the concepts developed in these models in actual clinical samples and cases. It is gratifying to see how well these concepts "translate" into the clinical setting. A very active area of research that is linking the laboratory to the clinic is the dissection of the biology and elucidation of the significance of proliferate breast disease and the identification of true, "high risk" or "preneoplastic" legions within the previously ill-defined spectrum of fibrocystic or benign breast disease. One anticipates that discoveries made here will also lead to earlier detection, intervention and prevention of life-threatening cancer.
Even, however, as we look with optimism to the eventual eradication of breast cancer, we are once again forced to face the reality that we have not yet achieved our goal. Thus, we are saddened by the much too premature death of Dr. Helene Smith from breast cancer. Helena's work was at the forefront of efforts to understand the biology of human breast cancer at the molecular level. Her insight, open-mindedness, and refusal to sacrifice relevance for convenience will continue to set the standard for all breast cancer researchers. This volume is dedicated to her memory.

This is a practical textbook written for use by engineers, scientists and technicians. It is not intended to be a rigorous scientific treatment of the subject material, as this would fill several volumes. Rather, it introduces the reader to the fundamentals of the subject material, and provides sufficient references for an in-depth study of the subject by the interested technologist. The author has a lifetime teaching credential in the California Community College System. Also, he has taught technical courses with the American Vacuum Society for about 35 years. Students attending many of these classes have backgrounds varying from high-school graduates to Ph.D.s in technical disciplines. This is an extremely difficult class profile to teach. This book still endeavors to reach this same audience. Basic algebra is required to master most of the material. But, the calculus is used in derivation of some of the equations. The author risks use of the first person "I," instead of "the author," and "you" instead of "the reader." Both are thought to be in poor taste when writing for publication in the scientific community. However, "I" am writing this book for "you" because the subject is exciting, and I enjoy teaching you, perhaps, something new. The book is written more in the vein of a "one-on-one" discussion with you, rather than the author lecturing to the reader. There are anecdotes, and examples of some failures and successes I have had over the last forty-five years in vacuum related activities, I'll try not to understate either.
Lastly, there are a few equations which if memorised will help you as a vacuum technician. There are less than a dozen equations and half that many "rules of thumb" to memorize, which will be drawn on time an again in designing, operating and trouble-shooting any vacuum system.

Since its inception in the famous 1936 paper by Birkhoff and von Neumann entitled "The logic of quantum mechanics" quantum logic, i.e. the logical investigation of quantum mechanics, has undergone an enormous development. Various schools of thought and approaches have emerged and there are a variety of technical results.
Quantum logic is a heterogeneous field of research ranging from investigations which may be termed logical in the traditional sense to studies focusing on structures which are on the border between algebra and logic. For the latter structures the term quantum structures is appropriate.
The chapters of this Handbook, which are authored by the most eminent scholars in the field, constitute a comprehensive presentation of the main schools, approaches and results in the field of quantum logic and quantum structures. Much of the material presented is of recent origin representing the frontier of the subject.
The present volume focuses on quantum structures. Among the structures studied extensively in this volume are, just to name a few, Hilbert lattices, D-posets, effect algebras MV algebras, partially ordered Abelian groups and those structures underlying quantum probability.
- Written by eminent scholars in the field of logic
- A comprehensive presentation of the theory, approaches and results in the field of quantum logic
- Volume focuses on quantum structures

This book aims to help the reader to understand what motivates people to engage in risk taking behavior, such as participating in traffic, sports, financial investments, or courtship. The consequences of risk taking may be positive, or result in accidents and injuries, especially in traffic. The wealth of studies and theories (about 1000 references) is used to offer a cohesive, holistic view of risk motivation. The risk motivation theory is a dynamic state-trait model incorporating physiological, emotional and cognitive components of risk perception, processing and planning. If a deficit exists between desired and perceived risk, risk compensation behavior results. A feedback loop provides new information for the next perception-motivation-behavior process. Assumptions were tested and support was found with 120 subjects in a longitudinal study. The concepts and findings are discussed in relation to psychological theories and their meaning for our daily lives.

Recent decades have seen a very rapid success in developing numerical methods based on explicit control over approximation errors. It may be said that nowadays a new direction is forming in numerical analysis, the main goal of which is to develop methods ofreliable computations. In general, a reliable numerical method must solve two basic problems: (a) generate a sequence of approximations that converges to a solution and (b) verify the accuracy of these approximations. A computer code for such a method must consist of two respective blocks: solver and checker.
In this book, we are chiefly concerned with the problem (b) and try to present the main approaches developed for a posteriori error estimation in various problems.
The authors try to retain a rigorous mathematical style, however, proofs are constructive whenever possible and additional mathematical knowledge is presented when necessary. The book contains a number of new mathematical results and lists a posteriori error estimation methods that have been developed in the very recent time.
- computable bounds of approximation errors
- checking algorithms
- iteration processes
- finite element methods
- elliptic type problems
- nonlinear variational problems
- variational inequalities

In 1974 the editors of the present volume published a well-received book entitled Latin Squares and their Applications''. It included a list of 73 unsolved problems of which about 20 have been completely solved in the intervening period and about 10 more have been partially solved.
The present work comprises six contributed chapters and also six further chapters written by the editors themselves. As well as discussing the advances which have been made in the subject matter of most of the chapters of the earlier book, this new book contains one chapter which deals with a subject (r-orthogonal latin squares) which did not exist when the earlier book was written.
The success of the former book is shown by the two or three hundred published papers which deal with questions raised by it.

This is the third volume in a series on membrane protein transfer. Membrane protein transport underlies the topological disposition of many proteins within cells and it is this disposition that allows for the co-ordination of the central cellular processes, such as metabolism.

Research of the past ten years has made it increasingly clear that domestic animals and wild animals differ in their nutritional requirements. Nutritional management, beneficial to domestic animals, may actually be life-threatening to wild ones. This new edition of Wildlife Feeding and Nutrition has been thoroughly updated to reflect recent insights, especially with regard to wildlife nutrition essential to successful management either in the wild or in captivity.
Zoological garden and laboratory personnel, wildlife biologists, ecologists, animal nutritionists, and veterinarians will benefit from this new edition.

Why a Second Edition?
The Second Edition provides practical answers to the general question, "How can I obtain useful sequence information from my protein or peptide?" rather than the more specific question asked in the first edition, "How can I obtain the N-terminal sequence?" Important new methods include ways of dealing with blocked N termini, computer analysis of protein sequences, and the recent revolution in mass spectrometry.
Key Features
Highlights of the Second Edition:
* Mass spectrophotometric characterization of proteins and peptides
* N-terminal sequencing of proteins with blocked N termini
* Internal amino acid sequence analysis after protease digestion in-gel and on-blot
* Improved microscale peptide purification methods
* Computer analysis of protein sequences
* New protocols tested and refined through everyday use in authors' laboratories
* Updated reference chapter covering all aspects of protein microsequencing

New models for dislocation structure and motion are presented for nanocrystals, nucleation at grain boundaries, shocked crystals, interphase interfaces, quasicrystals, complex structures with non-planar dislocation cores, and colloidal crystals. A review of experimentally established main features of the magnetoplastic effect with their physical interpretation explains many diverse results of this type. The model has many potential applications for forming processes influenced by magnetic fields.

The need for clean air has probably never been greater. Many industrial employees need to avoid exposure to airborne particulates, while certain industrial processes demand clean air of exceptional quality. Medical and biological fields rely on sterile air, while filtration can improve air quality in offices, homes and all types of transport. Filters act in a variety of complex and subtle ways. Each chapter introduces its subject matter simply, before tackling the problem in greater depth. The book therefore provides an excellent basis for detailed study, but is also invaluable to anyone needing an overview of the subject. Essential reading for industrial hygienists and engineers requiring an understanding of filtration, and for anyone whose work involves the maintenance or monitoring of air quality.
