This book is about some recent work in a subject usually considered part of "logic" and the" foundations of mathematics", but also having close connec tions with philosophy and computer science. Namely, the creation and study of "formal systems for constructive mathematics". The general organization of the book is described in the" User's Manual" which follows this introduction, and the contents of the book are described in more detail in the introductions to Part One, Part Two, Part Three, and Part Four. This introduction has a different purpose; it is intended to provide the reader with a general view of the subject. This requires, to begin with, an elucidation of both the concepts mentioned in the phrase, "formal systems for constructive mathematics". "Con structive mathematics" refers to mathematics in which, when you prove that l a thing exists (having certain desired properties) you show how to find it. Proof by contradiction is the most common way of proving something exists without showing how to find it - one assumes that nothing exists with the desired properties, and derives a contradiction. It was only in the last two decades of the nineteenth century that mathematicians began to exploit this method of proof in ways that nobody had previously done; that was partly made possible by the creation and development of set theory by Georg Cantor and Richard Dedekind.
Gaseous Air Pollutants and Plant Metabolism mainly talks about plants and air pollution. The publication of this book is inspired by a symposium on plants and pollution, which generated great interest among the personnel related to the field. The book begins with a brief background on air pollution and continues with a discussion on different types, effects, and solutions to the pollution. The book also features studies about the gaseous air pollution in North America, China, and Japan. The chapters that follow explore the different effects of pollution on chloroplasts, respiration, biochemistry, plant, and plant cells. The text is a valuable reference to undergraduates or postgraduates of chemistry and its related studies.
This volume investigates the links between the incidence of diet-related cancers and dietary patterns within Europe. It presents current understanding of the major cancers thought to be caused by diet alongside detailed data on regional variations in dietary composition, and collates these sets of information to illustrate associations between food
Intended as a text for the postgraduate students of political science, this well-researched book attempts to track the evolution of political ideas in the recent past and their background. It brings out the contemporary epistemological and methodological debates within the discipline and social sciences as a whole, and incorporates the latest developments in the field. Divided into forty chapters under eleven parts, the book deals with the core concepts and debates in political theory, and focuses on the state-society interactions. It tries to explain how the states, societies and cultures have responded to the emerging challenges thrown up by the social, economic and political factors, and the direction of the response. It also dwells on the impact of globalisation on current trends. Finally, the book analyses the ideas of modern Indian thinkers such as V.D. Savarkar, Jawaharlal Nehru, Ram Manohar Lohia, B.R. Ambedkar and Jayaprakash Narayan. Besides the postgraduate students of political science, the book would also be useful to the aspirants of civil services examinations and the initiated readers.
Asymmetric synthesis has become a major aspect of modern organic chemistry. The stereochemical properties of an organic compound are often essential to its bioactivity, and the need for stereochemically pure pharmaceutical products is a key example of the importance of stereochemical control in organic synthesis. However, achieving high levels of stereoselectivity in the synthesis of complex natural products represents a considerable intellectual and practical challenge for chemists. Written from a synthetic organic chemistry perspective, this text provides a practical overview of the field, illustrating a wide range of transformations that can be achieved. The book captures the latest advances in asymmetric catalysis with emphasis placed on non-enzymatic methods. Topics covered include: Reduction of alkenes, ketones and imines Nucleophilic addition to carbonyl compounds Catalytic carbon-carbon bond forming reactions Catalytic reactions involving metal carbenoids Conjugate addition reactions Catalysis in Asymmetric Synthesis bridges the gap between undergraduate and advanced level textbooks and provides a convenient point of entry to the primary literature for the experienced synthetic organic chemist.
