The principal text translated in this volume is the "Ta'rikh Al-sudan" of the 17th-century Timbuktu scholar, 'Abd al-Rahman al-Sadi. The other documents include an English translation of Leo Africanus's description of West Africa and some letters relating to Sa'dian diplomacy.
A wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, and radiofrequency and microwave techniques. On the fundamental side the book focuses on physical principles and the impact of spectroscopy on our understanding of the building blocks of matter, while in the area of applications particular attention is given to those in chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophyscis. The Fourth Edition also provides the reader with an update on laser cooling and trapping, Bose-Einstein condensation, ultra-fast spectroscopy, high-power laser/matter interaction, satellite-based astronomy and spectroscopic aspects of laser medicine.
Charles Messier's catalog of nebulae and star clusters, published in 1784, marked the start of a new era of deep-sky astronomy. Today, this tradition of observing galaxies and clusters is kept alive by dedicated amateur astronomers. Nearly all the objects are visible in a small telescope, and many, such as the Crab Nebula and the Andromeda galaxy, are among the most fascinating objects in the universe. Kenneth Glyn Jones has revised his definitive version of Messier's catalog. His own observations and drawings, together with maps and diagrams, make this a valuable introduction to deep-sky observing. Historical and astrophysical notes bring the science of these nebulae right up to date. This is a unique handbook, unlikely ever to be equaled in its completeness and importance to the telescope owner.

Similarly, all kinds of parts of mathematics serve as tools for other parts and for other sciences. Applying a simple rewriting rule to the quote on the right above one finds such statements as: 'One service topology has rendered mathematical physics .. .'; 'One service logic has rendered com puter science .. .'; 'One service category theory has rendered mathematics .. .'. All arguably true. And all statements obtainable this way form part of the raison d'etre of this series.
According to the presented studies, the health condition of animals in rearing and breeding should be regularly monitored. This would allow early detection of delicate deviations in the body of clinically healthy individuals. Unfortunately, regular monitoring of the health of animals in commercial production is not performed. It follows that this type of research should be an introduction to further, more inquisitive steps. This can form the basis for further courses of action, indicating which organs or tissues field doctors or researchers should be interested in and what to pay attention to in order to find the correct answer, concerning the situation in the animal body. In the future, we ...
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 aresolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts airns 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 ...
The human body is composed of several systems and organs, consisting of millions of cells that need relatively stable conditions to function and contribute to the survival of the body as a whole. The maintenance of stable conditions for the cells against the variations of the external environment is an essential function of the body and is called homeostasis. As a consequence of the loss of homeostasis, a disease is manifested. This book aims to provide the reader with an up-to-date view of the self-regulatory mechanisms that are activated to achieve homeostasis, the pathways that are altered during the disease process, and how medicine can intervene to restore balance in critical patients.
