One of the most active areas of contemporary organic chemistry involves the search for new catalysts that borrow concepts, strategies and even components from enzymes but yet are not found in nature. Such artificial enzymes not only give enormous insights into the mechanisms of enzyme catalysis but also offer the potential for catalyzing a wide range of chemical reactions with no counterpart in nature. Several approaches have been taken in the deVelopment of new catalysts, some based on biological methods and others on synthetic techniques. Site directed mutagenesis has allowed the direct...

'the oldest biography of Spinoza', La Vie de Mr. Spinosa, which in the manuscript copies is often followed by L'Esprit de M. Spinosa. Margaret Jacob, in her Radical Enlightenment, contended that the Traite was written by a radical group of Freemasons in The Hague in the early eighteenth century. Silvia Berti has offered evidence it was written by Jan Vroesen. Various discussions in the early eighteenth century consider many possi ble authors from the Renaissance onwards to whom the work might be attributed. The Trois imposteurs has attracted quite a bit of recent attention as one of the most...

This book is the result of many years of research in Non-Euclidean Geometries and Geometry of Lie groups, as well as teaching at Moscow State University (1947- 1949), Azerbaijan State University (Baku) (1950-1955), Kolomna Pedagogical Col lege (1955-1970), Moscow Pedagogical University (1971-1990), and Pennsylvania State University (1990-1995). My first books on Non-Euclidean Geometries and Geometry of Lie groups were written in Russian and published in Moscow: Non-Euclidean Geometries (1955) Ro1], Multidimensional Spaces (1966) Ro2], and Non-Euclidean Spaces (1969) Ro3]. In Ro1] I...

Edith Stein has become almost a legend in recent years largely because of her heroic personality and her death in Auschwitz at the hands of the Nazis. She is known also as an eminent German-jewish-Christian intellectual and feminist, but more in the realm of the sacred than of the secular. Both are essential to understanding her. To know the real Edith Stein one must have some knowledge of her as philosopher, for philosophy was central to her very being. For this reason the present work is designed to be of interest to the general reader as well as to philosophers. Many of the latter have...

The astronomer Jan Hendrik Oort (1900-1992) left behind an extensive collection of notes and correspondence, both on his research and on matters that concerned him in a variety of official functions. Upon Oort's death, the collection was augmented by more personal papers, letters, journals, and diaries. The resulting collection forms a rich source of information on many aspects of twentieth-century astronomy, in which Oort played such an important role. The scientific and personal material covers the entire span of time from Oort's early youth until his death. To make these papers accessible...

Relevant to philosophy, law, management, and artificial intelligence, these papers explore the applicability of nonmonotonic or defeasible logic to normative reasoning. The resulting systems purport to solve well-known deontic paradoxes and to provide a better treatment than classical deontic logic does of prima facie obligation, conditional obligation, and priorities of normative principles.

Dry granular materials, such as sand, sugar and powders, can be poured into a container like a liquid and can also form a pile, resisting gravity like a solid, which is why they can be regarded as a fourth state of matter, neither solid nor liquid. This book focuses on defining the physics of dry granular media in a systematic way, providing a collection of articles written by recognised experts. The physics of this field is new and full of challenges, but many questions (such as kinetic theories, plasticity, continuum and discrete modelling) also require the strong participation of...

Polymers, main components of plastics and rubbers, are being discarded in increasing quantities. But this waste can also be considered as plastic gold'. Public concern, coupled with the inherent value of the material, means that recycling is imperative. The present book presents a survey of current knowledge in the form of case studies, including current legal and educational issues. Topics covered also include regulation and practice in NATO countries, the economics of recycling, the reprocessing of single polymers and mixtures, and future prospects and strategies. Audience: ...

A general and introductory survey of foams, emulsions and cellular materials. Foams and emulsions are illustrations of some fundamental concepts in statistical thermodynamics, rheology, elasticity and the physics and chemistry of divided media and interfaces. They also give rise to some of the most beautiful geometrical shapes and tilings, ordered or disordered. The chapters are grouped into sections having fairly loose boundaries. Each chapter is intelligible alone, but cross referencing means that the few concepts that may not be familiar to the reader can be found in other chapters...
