The conference provided an ideal forum for automatic control researchers from around the world to present their results and exchange both ideas and experience. The aim of the conference was to report recent research on various aspects of system analysis and applications, to identify future trends in this area and to promote applications of the structural approach of control theory.…

Buch. Condizione: Neu. Neuware - The series Advances in Dendritic Macromolecules aims to cover the synthesis and supramolecular chemistry of dendritic or cascade super-molecules as well as their less perfect hyperbranched cousins.In Volume 3, Chapter 1 describes the synthesis and characterization of dendrimers and hyperbranched polyesters, both based on 2,2-bis(hydroxymethyl)propionic acid, as the AB2-monomer. Chapter 2, discusses the advantages and drawbacks of dendritic molecular architectures necessary to create polymeric organic magnetic materials. In Chapter 3, Balzani and colleagues delineate their contributions to the field of polynuclear transition metal complexes in the design and construction of dendritic nanostructures; these luminesence and redox-active complexes suggest their role as photochemical molecular devices operating by photoinduced energy and electron transfer processes. Chapter 4, reviews the overall progress on redox-active dendrimers, especially as redox catalysts, organic conductors, modified electrodes, and models for electron transfer proteins. Chapter 5, summarizes the pioneering research in organometallic dendritic macromolecules and then delineates the redox properties of a series of silicon-based ferrocenyl-containing dendrimers.…

Buch. Condizione: Neu. Neuware - The aim of this text is to provide reviews and monographs on topics involving molecular similarity, ranging from the fundamental physical properties underlying molecular behaviour to applications in industrially important fields such as pharmaceutical drug design and molecular engineering. The editors hope that this series will encourage new ideas and approaches, help to systematize the rapidly accumulating new chemical information, and make chemistry better understood and better applied.…

Buch. Condizione: Neu. Neuware - Volume 5 of Biomembranes covers an important group of membrane proteins, the ATPases. The P-type ATPases couple the hydrolysis of ATP to the movement of ions across a membrane and are characterized by the formation of a phosphoyrlated intermediate. Included are the plasma membrane and muscle sarcoplasmic reticulum Ca2+ -ATPases, the (Na+ -K+) -ATPase, the gastric (H+ -K+) -ATPase, the plasma membrane H+ -ATPase of fungi and plants, the Mg2+ - transport ATPase, the Salmonella typhimurium, and the K+ -ATPase of Escherichia coli, KdpB. The other important classes of ATPase in eukaryotic systems are the vacuolar H+ -ATPases and the F0F1 ATP synthase, and, in bacteria, the anion-translocating ATPases, responsible for resistance to arsenicals and antimonials, and the (Na+ -Mg2+) -ATPase of Acholeplasma. Finally, eukaryotic systems contain a variety of ectonucleotidases important, for example, in hydrolysis of extracellular ATP released as a cotransmitter from cholinergic and adrenergic nerve terminals. Volume 5 of Biomembranes explores structure-function relationships for these mebrane-bound ATPases.…

Buch. Condizione: Neu. Neuware - A comprehensive reference work for teaching at graduate level and research in empirical finance. The chapters cover a wide range of statistical and probabilistic methods applied to a variety of financial methods and are written by internationally renowned experts.

Buch. Condizione: Neu. Neuware - Volume 11 of this series presents five timely reviews on current research on alkaloids. Chapter 1 by Paul L. Schiff, Jr. is a monumental survey of research that has been carried out over the past decade on the Thalictrum alkaloids. Forty-six new alkaloids are described from fifteen species of the genus Thalictrum, as well as 116 alkaloids of known structure from thirty-six species and subspecies of the genus. The chapter includes discussions of isolation and structure elucidation, analysis, biosynthesis, cell culture, and pharmacology. Also featured are inclusive compilations of botanical sources, alkaloids by alkaloid types, and calculated molecular weights of the Thalictrum alkaloids.Chapter 2 by Giovanni Appendino provides a fascinating treatment of Taxine, a collective name referring to a mixture of diterpenoid alkaloids from the yew tree (genus: Taxus). Taxine is responsible for the toxic properties of the yew tree that has been documented in historical and fictional literature, from Julius Caesar to Shakespeare, and from Agatha Christie to T.S. Eliot. The chapter treats the history, isolation techniques, structure elucidation, chemistry, and pharmacology of Taxine.Chapter 3 by Mary D. Menachery surveys the alkaloids of South American Menispermaceae (moonseed family). Many different structural types are included in this family. The alkaloid-bearing plants are woody-vines, shrubs, or small trees. Several of these species possess potent curare activity. The chemistry as well as pharmacology of these alkaloids is summarized.Chapter 4 by Russell J. Molyneux, Robert J. Nash, and Naoki Asano treats the chemistry and biological activity of the calystegines and related nortropane alkaloids. These polyhydroxylated bicyclic alkaloids represent another class of compounds that inhibit glycosidases, producing profound effects in biological systems by disrupting the essential cellular function of glycoprotein processing.Chapter 5, a related chapter by Robert J. Nash, Naoki Asano, and Alison A. Watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. Topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.…

Buch. Condizione: Neu. Neuware - In the last decade parallel computing has been put forward as the only computational answer to the increasing computational needs arising from very large and complex fluid dynamic problems. Considerable efforts are being made to use parallel computers efficiently to solve several fluid dynamic problems originating in aerospace, climate modelling and environmental applications.Parallel CFD Conferences are international and aim to increase discussion among researchers worldwide.Topics covered in this particular book include typical CFD areas such as turbulence, Navier-Stokes and Euler solvers, reactive flows, with a good balance between both university and industrial applications. In addition, other applications making extensive use of CFD such as climate modelling and environmental applications are also included.Anyone involved in the challenging field of Parallel Computational Fluid Dynamics will find this volume useful in their daily work.…

Buch. Condizione: Neu. Neuware - The very latest information on adverse drug effects from the international literature, compiled by an international team of experts. New reports are presented of adverse drug effects, critically analysed in context, in terms of clinical relevance and importance, and cross-referring to previous reports where necessary. New adverse effects are reported and evaluated, and previously reported adverse effects are re-evaluated in the light of the most recent information.

Two separate indexes enhance the use of the book, allowing the reader to access information by drug name or by, adverse effects.…

Buch. Condizione: Neu. Neuware - Vertisols, one of the eleven established soil orders, are clay soils with unusual and interesting properties. They cover more than 350 million hectares of land in the world and in tropical Africa alone there are over 100 million hectares. Because of their very small particle size and high surface area, these soils have higher physical and chemical reactivity than other soils. Their interaction with agrochemicals/industrial wastes, has been, increasingly, the subject of research especially in the last two decades. Vertisols create special problems when used for engineering purposes.This book is intended to provide comprehensive and state-of-the-art information about Vertisols worldwide. Special attention is given to the use and management of soils such as fertilizer use, crop selection, soil tillage, water restriction on land including irrigation, and soil erosion. A special chapter has been added to deal with geotechnical engineering of Vertisols.Vertisols have great potential for agricultural production but many, especially in the developing world, are underutilized due to a lack of understanding regarding their behaviour and management.This book is written by leading scientists worldwide. It is expected that this monograph will be of great use to soil scientists and agronomists, graduate and senior graduate students.Improvement of their management may solve the current food deficiency in the world.…
