This book is a collection of sixteen papers on various aspects of rotation in the solar system. Topics discussed include the evolution of rotation in the early history of the solar system, the interaction of rotation and magnetic field in the solar system, the rotation of the Sun, the primeval axis of rotation of the Moon, tidal friction in the Earth-Moon system, the determination and interpretation of fluctuation in the Earth's rotation and polar motion, rotation of the atmospheres of the Earth and planets, rotation in the Jovian, Saturnian and Uranian systems, and the rotation of asteroids and cometary nuclei.
Protozoal diseases continue to exact a tragic toll of human life in many tropical and subtropical countries. The potential importance of immunoprophylactic measures in parasite infections is immense, though this goal has remained elusive. This volume records papers presented at a Royal Society Discussion Meeting held in February 1984 concerned with the application of recent technical advances to the study of human protozoal diseases and the development of practical and effective vaccines.
This volume describes the nature of five major biological minerals (calcium carbonates, calcium phosphates, silica, iron oxides and ice) and the organic molecules that are found to be associated with them. Biological minerals are in fact usually composites and their form is not characterized by the known crystal habits of the inorganic microcrystals from which they are made. The underlying chemistry and physics of the composite minerals described here shows that their beauty hides very sophisticated functional properties. The papers also describe the ways in which the materials are synthesized in controlled ways. The likely pattern of future research is highlighted repeatedly by the description of new methods.
This volume examines the neural mechanisms of nociception and pain. Neurochemical mechanisms have been illuminated by the new techniques of immunocytochemistry and the explosion of knowledge of the neuropeptides. These developments in basic knowledge are reviewed in accounts of nociceptive systems in trigeminal, visceral, thalamic and cerebral cortex. The book concludes with an account of mechanisms of endogenous antinociception.
