Buch. Zustand: Neu. Neuware - Demonstrates the wide scope of cycloaddition reactions, including the Diels-Alder reaction, the ene reaction, 1,3-dipolar cycloadditions and [2+2] cycloadditions in organic synthesis. The author, a leading exponent of the subject, illustrates the ways in which they can be employed in the synthesis of a wide range of carbocyclic and heterocyclic compounds, including a variety of natural products of various types. Special attention is given to intramolecular reactions, which often provide a rapid and efficient route to polycyclic compounds, and to the stereochemistry of the reactions, including recent and developing work on enantioselective synthesis.…

Taschenbuch. Zustand: Neu. Neuware - The journal Chemometrics and Intelligent Laboratory Systems has a specific policy of publishing tutorial papers, (i.e. articles aiming to discuss and illustrate the application of chemometric and other techniques) solicited from leading experts in the varied disciplines relating to this subject. This book comprises reprints of tutorials from the first 5 volumes of this journal, covering the period from late 1986 to mid 1989. The authors of the papers include analytical, organic and environmental chemists, statisticians, pharmacologists, geologists, geochemists, computer scientists and biologists, which reflects the strong interdisciplinary communication. The papers have been reorganized into major themes, covering most of the main areas of chemometrics. This book is intended both as a personal reference text and as a useful background for courses in chemometrics and laboratory computing.…

Buch. Zustand: Neu. Neuware - During the past two decades, there has been a dramatic increase in interest in the study of aging-related changes in cognitive abilities. In this volume researchers from a variety of theoretical perspectives discuss adult age differences in a wide range of cognitive skills. Of special interest is the extent to which aging effects on performance are related to variations in the representation, organization, and utilization of knowledge, broadly defined. Recent research and theory in the field of aging has emphasized the need to examine such processes more closely in order to provide a more complete understanding of aging effects on cognitive behavior.…
