Studies in Natural Products Chemistry
In Volume 18 of this well-established series, Professor Atta-ur-Rahman again brings together the work of several of the world's leading authorities in organic chemistry. Their contributions demonstrate the rapid, ongoing development of this field by illustrating many of the latest advances in synthetic methods, total synthesis, structure determination, biosynthetic pathways, and biological activity.The opening chapter presents an overview of strategies for the synthesis of several classes of natural products with an emphasis on complex polycyclic systems. Subsequent chapters discuss the synthesis of specific classes of compounds, including morphine, polyketides, acetogenins, nonactic acid derivatives, complex spirocyclic ethers, ä-lactam and pyridone derivatives, inositol phosphates, sphingolipids, brassinosteroids, Hernandia lignans, and dimeric steroidal pyrazine alkaloids. Finally, the ever stronger links between chemistry and biology are reinforced by chapters on the origin and function of secondary metabolites, bioactive conformations of gastrin hormones, and immunochemistry.
Alkaloids: Chemical and Biological Perspectives
Volume 13 of this series presents five timely reviews of research on alkaloids such as new developments in the chemistry and biology of alkaloids from amphibian skins. It provides a synopsis and tabulation of the hundreds of alkaloids that have been detected, with an emphasis on occurrence, structure, dietary origins, and biological activity. Alkaloids containing the 1, 2, 3, 3a, 8, 8a - hexahydropyrrolo [2,3b] indole ring system and the cyclotryptamines are discussed. An exhaustive list of available structures is provided. The chemical and biological structures have been evaluated critically so as to identify existing errors and expose irregularities in appearance or biological function. In...

Migrations and Dispersal of Marine Organisms
This book represents the Proceedings of the 37th European Marine Biology Symposium, held in Reykjavík, Iceland, 5-9 August 2002. The main themes of the symposium were Migrations and Dispersal of Marine Organisms. These themes are highly relevant today. There is widespread man-aided dispersal (e.g. by ballast water) of marine plants and animals, which may have substantial effects on the regions receiving new species. The new introductions may result in reduced diversity of plants and animals and may affect natural resources in the countries receiving toxic algae and other foreign elements. Studies of changes in distribution and dispersal of marine animals and plants are also highly relevant with reference to the changing climate taking place. The study of dispersal has recently gained new impetus with the discovery of the remarkable communities found on isolated hydrothermal vents and cold water seeps in the world's oceans.
The Surface Waters Acidification Programme
This 1991 volume presents the results of a major study of the mechanism and consequences of surface water acidification. It provides an overview of the chemical process involved in acidification and of its biological impact on freshwater life. The surface waters acidification programme (SWAP) has drawn together the many facets of this complex phenomenon.
Progress in the Chemistry of Organic Natural Products
The objective of this ASI was to bring together specialists in several complex variables (many of whom have contributed to complex potential theory) and specialists in potential theory (all of whom have contributed to several complex variables) together with young researchers and graduate students for an interchange of ideas and techniques. Not only was the status of current research presented, but also the relevant background, much of which is not yet available in books. The following topics and interconnections among them were discussed: 1. Real and Complex Potential Theory. Capacity and approximation, basic prop erties of plurisubharmonic functions and methods to manipulate their singular...
Progress in Heterocyclic Chemistry
This is the fifteenth annual volume of Progress in Heterocyclic Chemistry, which covers the literature published during 2002. The volume opens with three reviews on current heterocyclic topics. The highlight chapters in Volume 15 are all written by leading researchers in their field and these chapters constitute a systematic survey of the important original material reported in the literature on heterocyclic chemistry in 2002. As with previous volumes in the series, Volume 15 will enable the reader to keep abreast of developments in heterocyclic chemistry in an effortless way. A critical review of the heterocyclic literature published during 2002 Opens with three specialized reviews on new developing topics of interest to heterocyclic chemists. Subsequent chapters review advances in the formation and reaction of heterocyclic rings Chapters all written by leading researchers in their field

Fungicides
Fungicides are a class of pesticides used for killing or inhibiting the growth of fungus. They are extensively used in pharmaceutical industry, agriculture, in protection of seed during storage and in preventing the growth of fungi that produce toxins. Hence, fungicides production is constantly increasing as a result of their great importance to agriculture. Some fungicides affect humans and beneficial microorganisms including insects, birds and fish thus public concern about their effects is increasing day by day. In order to enrich the knowledge on beneficial and adverse effects of fungicides this book encompasses various aspects of the fungicides including fungicide resistance, mode of action, management fungal pathogens and defense mechanisms, ill effects of fungicides interfering the endocrine system, combined application of various fungicides and the need of GRAS (generally recognized as safe) fungicides. This volume will be useful source of information on fungicides for post graduate students, researchers, agriculturists, environmentalists and decision makers.
Petroleum Biotechnology
This book is one of a kind in the field of petroleum biorefining and biological upgrade of petroleum; it presents a critical review as well as an integrated overview of the potential biochemical processes, bridging the gap between academia and industry. It addresses today's demanding production challenges, taking into account energy efficient and environmentally friendly processes, and also looks at the future possibility of implementing new refinery systems. Suitable for those practitioners the petroleum industry, students and researchers interested in petroleum biotechnology.* Covers a new application field for biotechnology* Looks at innovative processes for the petroleum industry* Presents examples of modern environmental processes
