The last twenty years have seen an enormous growth in the number of studies on the role of complexes in free-radical polymerization. New possibilities for polymerization initiation and the significant influence on the kinetics of the elementary polymerization reactions, such as propagation, chain transfer, and termination, are the main areas which have attracted attention from specialists in this field. The most important breakthrough has probably been made in the regulation of free-radical polymerization by various complex-forming substances. Advances in this area have not only contributed to the better understanding of the kinetics and mechanism of radical chain reactions, but they have also created a background for the solution of some practical problems associated with the synthesis of new polymeric materials. This volume provides a survey of the latest achievements in the field of free-radical polymerization. The scope of the volume permits the presentation of these extensive problems in a concise form only, nevertheless it contains an invaluable source of information on topical questions relating to the participation of complexes in free-radical polymerization.

Complex groups of associations arising out of the unconscious have been known and described in all cultures and are integral to the healthy psyche. Breuer first coined the term complexes to describe certain personalities. Jung developed the concept further, assigning the shell of the complex with its amplifications and associations to the personal unconscious and postulating a core that is archetypal in nature and rooted in the collective unconscious. In this book, Hans Dieckmann fills a lacuna by developing a general theory of the complexes that gives both the student and the practicing analyst an overview of this concept for the purposes of diagnosis and therapy. Illustrated throughout with clinical vignettes and diagrams, Complexes provides a clear and orderly path through the chaotic contents of analysis. CONTENTS: The Complex Structure of the Psyche The Structure of Complexes The Relationship of the Ego-complex to the Individual Complexes The Shell of the Complex and the Trigger Situation The Core of the Complex Diagnosing Positive and Negative Parental Complexes The Pathology of the Positive Mother Complexes The Formation of and Dealing with Symbols in the Complex Core, Exemplified in Two Borderline Cases The Oedipus Complex in Analytical Psychology

Stability constants are fundamental to understanding the behavior of metal ions in aqueous solution. Such understanding is important in a wide variety of areas, such as metal ions in biology, biomedical applications, metal ions in the environment, extraction metallurgy, food chemistry, and metal ions in many industrial processes. In spite of this importance, it appears that many inorganic chemists have lost an appreciation for the importance of stability constants, and the thermodynamic aspects of complex formation, with attention focused over the last thirty years on newer areas, such as organometallic chemistry. This book is an attempt to show the richness of chemistry that can be revealed by stability constants, when measured as part of an overall strategy aimed at understanding the complexing properties of a particular ligand or metal ion. Thus, for example, there are numerous crystal structures of the Li+ ion with crown ethers. What do these indicate to us about the chemistry of Li+ with crown ethers? In fact, most of these crystal structures are in a sense misleading, in that the Li+ ion forms no complexes, or at best very weak complexes, with familiar crown ethers such as l2-crown-4, in any known solvent. Thus, without the stability constants, our understanding of the chemistry of a metal ion with any particular ligand must be regarded as incomplete. In this book we attempt to show how stability constants can reveal factors in ligand design which could not readily be deduced from any other physical technique.

Following the Soviet invasion in 1979, the Mujahideen defenders of Afghanistan developed and reinforced many natural cave systems to use as supply bases and defensive positions. The Taliban and Al Qaeda further strengthened these positions in the 1990s. Following the events of September 11, 2001, these cave systems have once more come to prominence and sites such as Tora Bora and Zhawar Kili have featured in news headlines around the world. This title provides an analysis of these caves and underground systems, and discusses the U.S.-led Coalition's tactical approach to dislodging the enemy from these fortified positions.

Quelque chose a changé dans notre rapport aux animaux. La « cause animale » est à l'ordre du jour, et le vivant humain est désormais plus essentiellement animal qu'humain. Cela s'appelle un zoocentrisme : au centre de notre humanité, l'animalité. En apparence, nous avons tout à gagner à cette nouvelle image de l'homme. Elle nous vient de la biologie de l'évolution, qui nous a situés, quelque part dans l'ordre des primates, en bonne compagnie avec nos cousins les grands singes. Elle est aussi un appel à réformer et à moraliser nos relations avec les animaux que nous exploitons : on respecte d'autant mieux qui nous ressemble. Enfin l'animalité humaine fait de nous des esprits forts, qui ont su en finir avec les dualismes et les grands partages métaphysiques d'antan. Bref : c'est à tous égards une pensée progressiste, car ouverte à la science, généreuse envers les animaux, et philosophiquement éclairée. Il se pourrait pourtant que ces raisons d'en finir avec la différence homme-animal ne soient qu'un ensemble de pensées bancales qui, entre oubli des sciences humaines, réduction de la vie humaine à sa seule vulnérabilité et déni de ce que nous vivons en première personne, composent finalement le portrait idéologique d'un progressisme stérile. Pouvons-nous échapper au « complexe des trois singes », ces trois façons de méconnaître ce que nous vivons et faisons comme vivants humains ? Et pouvons-nous imaginer un progressisme de vérité conscient de tout ce que nous devons aux animaux sans pour autant renier ce que nous sommes ?

The interaction of transition metals with unsaturated molecules has led to fundamental insights in the nature of the chemical bond which, in turn, has provided the basis of important present-day applications such as transition metal mediated synthesis or homogeneous and heterogeneous catalysis. This slim volume outlines the chemistry and discusses the bonding in of some of the most important classes of organometallic compounds: the complexes of transition metals with Pi-ligands such as alkenes, alkynes, arenes, and cyclopentadienyl and allyl ligands. The material covered follows on from Organometallics I which covers the chemistry of complexes with metal-carbon delta-bonds. Synthetic and reactivity aspects of each class of compounds are illustrated with pertinent examples from the recent chemical literature. Highlighted excursions relate the fundamental chemistry to current synthetic or catalytic applications. Undergraduates, graduate students and lecturers will find this book to be a wonderful resource.

Drawing from several thousand cases of actual past-life memories recalled during regression, Walsh creates an essential sourcebook that not only illustrates the astrological foundation of the karmic scripts one is born with, but also how healing from unresolved issues from the past unlocks the evolutionary potential of the soul.

A graph complex is a finite family of graphs closed under deletion of edges. Graph complexes show up naturally in many different areas of mathematics. Identifying each graph with its edge set, one may view a graph complex as a simplicial complex and hence interpret it as a geometric object. This volume examines topological properties of graph complexes, focusing on homotopy type and homology. Many of the proofs are based on Robin Forman's discrete version of Morse theory.
