Recent advances in electrochemistry and materials science have opened the way to the evolution of entirely new types of energy storage systems: rechargeable lithium-ion batteries, electrochroms, hydrogen containers, etc., all of which have greatly improved electrical performance and other desirable characteristics. This book encompasses all the disciplines linked in the progress from fundamentals to applications, from description and modelling of different materials to technological use, from general diagnostics to methods related to technological control and operation of intercalation compounds. Designing devices with higher specific energy and power will require a more profound understanding of material properties and performance. This book covers the status of materials and advanced activities based on the development of new substances for energy storage.
This book discusses a particular aspect of brain function, that of storage and retrieval of memory of past experience, in terms of neuronal plasticity. In discussing this aspect of brain functions, however, it discusses brain mecha nisms in their wider sense as well. Clearly, the central nervous system is a highly interconnected system from all points of view, and it would not be possible to understand function in terms of only a single event or only a sin gle neurotransmitter. This is true for any biochemical activity that accompanies neuronal functional activity and accompanies behavior. The authors have commendably recognized this complexity, and recognize still more the need to present i...
Nanoporous materials are critical to various fields of research, including ion exchange, separation, catalysis, sensor applications, biological molecular isolation, and purification. In addition, they offer new opportunities in such areas as inclusion chemistry, guest-host synthesis, and molecular manipulations and reactions at the nanoscale. In St
Although individually and collectively Americans have many histories, the dominant view of our national past focuses on the colonial era. The reasons for this are many and complex, touching on stories of the country's origins and of the founding fathers, the privileged position in history granted the thirteen original colonies, and the ways in which the nation has adjusted to change and modernity. But no matter the cause, the result is obvious: images and forms derived from and related to America's colonial past are the single most popular form of cultural expression. Often conceived solely in architectural terms, from the red-brick and white-trimmed buildings that recall eighteenth-century ...
Animal models represent experimental investigations developed in one species for the purpose of studying phenomena in another species and provide numerous advantages for preclinical research. They allow scientists greater control and isolation of important experimental variables. Animal models are safe, reproducible strategies by which to evaluate and design new pharma cological treatment strategies, while also allowing direct central nervous system intervention to alter the course of the aberrant behavior. Animal models have been developed for a number of mental illnesses; in this particular domain, they hold the promise to shed light on the still obscure etiologies of these illnesses and u...

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 18 contains literature published in 1976 and received before March 1, 1977; some older liter ature which was received late and which is not recorded in earlier volumes is also included.
