In recent years the subject of pollution of natural waters by aquaculture has received considerable attention. With increasingly stringent regulation of wastewater quality from fish farms around the world, those involved in the industry need to be aware of the causes of pollution from fish and shellfish farms and of methods by which this pollution may be prevented. This book aims to bring the principles of wastewater treatment and other poll...

Fuzzy Sets in Decision Analysis, Operations Research and Statistics includes chapters on fuzzy preference modeling, multiple criteria analysis, ranking and sorting methods, group decision-making and fuzzy game theory. It also presents optimization techniques such as fuzzy linear and non-linear programming, applications to graph problems and fuzzy combinatorial methods such as fuzzy dynamic programming. In addition, the book also accounts for a...

The advent of low temperature superconductors in the early 1960's converted what had been a laboratory curiosity with very limited possibilities to a prac­ tical means of fabricating electrical components and devices with lossless con­ ductors. Using liquid helium as a coolant, the successful construction and operation of high field strength magnet systems, alternators, motors and trans­ mission lines was announced. These developments ushered ...

In many of nowadays web-based environments for electronic marketing and commerce, that present large multimedia product and service catalogues, it becomes more and more difficult to provide naive end users, such as private consumers or commercial business partners, with intuitive user interfaces to access the large multimedia collections describing the presented products and services. The same holds for marketing managers and other employees r...

This is the first thorough examination of weakly nonlocal solitary waves, which are just as important in applications as their classical counterparts. The book describes a class of waves that radiate away from the core of the disturbance but are nevertheless very long-lived nonlinear disturbances.

The problems of modern society are complex, interdisciplinary and nonlin­ ear. ~onlinear problems are therefore abundant in several diverse disciplines. Since explicit analytic solutions of nonlinear problems in terms of familiar, well­ trained functions of analysis are rarely possible, one needs to exploit various approximate methods. There do exist a number of powerful procedures for ob­ taining approximate solutions of nonlinear problems su...

In every scientific discipline there are milestones - periods of significant accom­ plishment when it is appropriate to pause and summarize the state of the field. Such is the case for the study of the behavior of cosmic rays in the heliosphere. We are just passing through solar minimum conditions, when the heliosphere has a well-ordered and relatively simple configuration. We have been fortunate to have an array of spacecraft - unprecedented ...

Written at a time when the transformation from urban to suburban lifestyle was underway, this work established the principle that in urban affairs, public policy follows the market. Greer poses major questions of urban existence, such as the gains and losses caused by urbanization.

The introduction of synthetic organic chemicals into the environment during the last few decades has given rise to major concern about the ecotoxicological effects and ultimate fate of these compounds. The pollutants that are considered to be most hazardous because of their intrinsic toxicity, high exposure level, or recalcitrant behavior in the environment have been placed on blacklists and other policy priority lists. The fate of synthetic c...

This volume is the selected, edited proceedings of the International Taurine Sympo­ th sium held in Tucson, Arizona, in July 1997. The meeting was a satellite symposium ofthe 16 Biennial Meeting of the International Society for Neurochemistry, which was held in Boston immediately following the Tucson meeting. In view of the desert location of Tucson, the meeting was advertised tongue-in-cheek as being the hottest scientific meeting ever. As th...

An intensive development of the theory of generalized analytic functions started when methods of Complex Analysis were combined with methods of Functional Analysis, especially with the concept of distributional solutions to partial differential equations. The power of these interactions is far from being exhausted. In order to promote the further development of the theory of generalized analytic functions and applications of partial differenti...

Over the weekend of 21-23 February 1997, a small group gathered in Tallahassee, Florida, at the invitation of Ted Williams, to discuss "photo stasis and related topics." The majority of participants were former students and colleagues of Ted's, but an occasional outsider such as myself was generously included. The papers presented there are collected in this volume. The theory of photo stasis was first outlined in a landmark paper by John Penn...

The letters of Confederate soldier Eli Pinson Landers.

This bibliography is a review of available information on indicators of sustainable land management and land quality. The report compiles, organizes, and summarizes available data and information on indicators and makes them accessible through the World Wide Web, email, and as printed reports. It is useful for research on indicators of sustainability, as well as for decisionmakers faced with implementing a sustainable land management component...

For all that new non-X-ray technologies such as MR and ultrasound and its various manifestations have made an enormous impact in recent years on the practice of medical imaging, the use of X-rays and X-ray contrast-enhancing agents has retained an important position at the heart of the process. Indeed, with its frequent requirements for high total dose regimes, CT has increased the use of contrast agents. Even helical/spiral CT which, it was i...

The cover picture of this volume displays one of the most advanced products of he­ lioseismic research: a view into the deep interior of the sun, revealing its distinctly non-uniform rotation throughout the entire depth of the convection zone. Just over 20 years ago, the first successful helioseismic experiment disclosed an increase of ro­ tation velocity in the uppermost one dozen megameters below the photosphere. The stunning progress in dep...

If present trends continue, most climatologists agree that the concentration of carbon dioxide in the atmosphere will have doubled by the year 2050. This increase in CO 2 will have a major effect on the global climate and substantially alter the physical, chemical and biological characteristics of lakes throughout the world. In recent years, it has become clear that year-to-year changes in the weather have a major effect on the seasonal dynami...

Intended for Key Stage 1 and 2 levels, this chart features a table of all the elements in their correct groups. Useful for whole-class teaching, it also contains information about the structure of an atom and the discovery of the Periodic Table. The groups are colour-coded for easy readability and differentiation.

When the author purchased a dilapidated South Carolina plantation in 1989 and began refurbishing it, he also found himself taking part in an act of cultural reclamation: piecing together the story of the Hardy family, who purchased the tract along the Tyger River in 1786 and farmed it for two centuries. 16 illustrations.

The last several years have been a landmark period in the ubiquitin field. The breadth of ubiquitin's roles in cell biology was first sketched, and the importance of ubiquitin-dependent proteolysis as a regulatory mechanism gained general acceptance. The many strands of work that led to this new perception are re­ counted in this book. A consequence of this progress is that the field has grown dramatically since the first book on ubiquitin was...
