The purpose of this monograph is to provide a summary for those who are active in the field of phthalocyanine research. This volume allows the reader to quickly-and at a reasonable cost-determine what is being accomplished so that he may plan his own research programs. It covers such topics as synthesis, reactions, inks, energy systems, coatings, toners, and electrophotographic plates and developers, just to name a few. Packed with over 40 structural drawings of phthalocyanine molecules, this one-of-a-kind reference provides the necessary description and visualization to stimulate further research. This work is an indispensable resource for researchers and practitioners, both novice and experienced, in the field of phthalocyanine science and technology.
The stars that form a halo around our Galaxy are intriguing; they have abundances of elements that suggest they are old. The properties of these 'hot stars' and similar stars in other galaxies challenge the well-established theory of stellar evolution in many ways. Studying the collective properties of these stars provides important input to many areas of astrophysics - including the formation of our Galaxy, stellar evolution and the stellar populations of other galaxies. The study of hot stars in the halo of our Galaxy is undergoing an exciting renaissance owing to important new observations with the Hubble Space Telescope and ASTRO1 and to techniques recently developed for ground-based observations. Advances in computers have also recently led to a far more detailed and complete theoretical understanding of stellar evolution. This volume, first published in 1994, draws together the proceedings of a conference held in Union College, New York, which gathered experts in the field in question.
Thoroughly revised and updated by internationally recognized experts, the Third Edition of this popular and widely used atlas reflects twelve years of vital advances in electrodiagnosis of neurologic function in neonates. The authors have distilled the vast, complex literature on neonatal EEG to provide a practical, contemporary, superbly illustrated guide to performing EEG in neonates and interpreting both common and unusual patterns.
This edition includes digital as well as analog EEG and features over 200 brand-new, full-sized reproductions of EEG tracings. The authors demonstrate state-of-the-art improvements in recording technique and highlight recent advances in the understanding of normal and abnormal brain development.
