Morphology, Molecules, Evolution and Phylogeny in Polychaeta and Related Taxa (Developments in Hydrobiology)

Book Description

Annelida, mainly consisting of marine Polychaeta and in faunal and partly parasitic Clitellata, is one the most significant metazoan taxa. Its more than 20.000 described species invade nearly all habitats and play a central role in marine benthic systems as well as in terrestrial soil communities. Annelids include all soft-bodied segmented worm-like organisms and have been recognized as a separate "phylum" for almost 200 years.

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships.

The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

Book Description

Polyunsaturated fatty acids are essential for human cell metabolism. As precursors of a very large and extremely versatile family of signaling compounds they play a key role in intracellular communication. Eicosanoids constitute one of the most abundant and prominent subfamilies of these fatty acid derivatives which are formed primarily along oxidative pathways. Prostaglandins, leukotrienes, and related eicosanoids have a modulatory function in mammalian cells and are responsible for tissue responses such as inflammation or wound repair. Increasing activity in eicosanoid research sheds new light on today's most common diseases including atherosclerosis, cancer, Alzheimer's, allergies, and rheumatic diseases. The recent advances already have far-reaching implications in medicine.

This detailed account, written by leading experts, covers the ground-breaking developments in recent eicosanoid research. The topics span eicosanoid biogenesis, new aspects of their pathophysiology, for example their influence on the cardiovascular system, as well as the clinical application of synthetic eicosanoids and their antagonists. Researchers and students working in biochemistry or in pharmaceutical, physiological, medicinal and neurochemistry will value this informative introduction to one of the most rapidly developing fields in cell biology.

Book Description

Nonlinear Systems is divided into three volumes. The first deals with modeling and estimation, the second with stability and stabilization and the third with control. This three-volume set provides the most comprehensive and detailed reference available on nonlinear systems. Written by a group of leading experts in the field, drawn from industry, government and academic institutions, it provides a solid theoretical basis on nonlinear control methods as well as practical examples and advice for engineers, teachers and researchers working with nonlinear systems. Each book focuses on the applicability of the concepts introduced and keeps the level of mathematics to a minimum. Simulations and industrial examples drawn from aerospace as well as mechanical, electrical and chemical engineering are given throughout.

Book Description

Presents and demonstrates stabilizer design techniques that can be used to solve stabilization problems with constraints. These methods have their origins in convex programming and stability theory. However, to provide a practical capability in stabilizer design, the methods are tailored to the special features and needs of this field. Hence, the main emphasis of this book is on the methods of stabilization, rather than optimization and stability theory. The text is divided into three parts. Part I contains some background material. Part II is devoted to behavior of control systems, taking examples from mechanics to illustrate the theory. Finally, Part III deals with nonlocal stabilization problems, including a study of the global stabilization problem.

Book Description

Switched linear systems have a long history in the control literature but-along with hybrid systems more generally-they have enjoyed a particular growth in interest since the 1990s. The large amount of data and ideas thus generated have, until now, lacked a co-ordinating framework to focus them effectively on some of the fundamental issues such as the problems of robust stabilizing switching design, feedback stabilization and optimal switching.

This deficiency is resolved by Switched Linear Systems which features:

• nucleus of constructive design approaches based on canonical decomposition and forming a sound basis for the systematic treatment of secondary results;

• theoretical exploration and logical association of several independent but pivotal concerns in control design as they pertain to switched linear systems: controllability and observability, feedback stabilization, optimization and periodic switching;

• a reliable foundation for further theoretical research as well as design guidance for real life engineering applications through the integration of novel ideas, fresh insights and rigorous results.

Primarily intended for researchers and engineers in the systems and control community, postgraduate students will also discover that this is perfect complementary reading especially for those studying intelligent, adaptive or robust control.

Book Description

On general grounds I deprecate prefaces. I have always thought that if an author cannot make friends with the reader, and explain his objects, in two or three hundred pages, he is not likely to do so in fifty lines. And yet the temptation of speaking a few words behind the scenes, as it were, is so strong that few writers are able to resist it. I shall not try.

Download Description

The episode with which this chapter is concerned is one that has often occurred on the out-post line of civilisation, and which is peculiarly frequent in the history of a people whose widespread Empire is fringed with savage tribes. A small band of soldiers or settlers, armed with the resources of science, and strengthened by the cohesion of mutual trust, are assailed in some isolated post, by thousands of warlike and merciless enemies. Usually the courage and equipment of the garrison enable them to hold out until a relieving force arrives, as at Rorke's Drift, Fort Chitral, Chakdara or Gulistan. But sometimes the defenders are overwhelmed, and, as at Saraghari or Khartoum, none are left to tell the tale.

A valid view.......2000-08-20

This is a book which I value tremendously. Rarely are books so well written as this; and whatever Churchill wrote in 1897 in this account still holds very much true, if not more so, for the context of this narrative. Were I to write an account on this subject today, it would hardly differ from Churchill's. His opinions are still very much valid, and those who value truthful methods of analysis are well aware of this. This book must not be spurned by experts. Given the nature of the current overall situation prevailing in this region and its effect on the rest of the world, this book becomes more important than ever as a reference primer.
